Digital Camera Patent Description
BACKGROUND OF THE INVENTION
[0001] This application claims the priority of Japanese Patent
Application No. 2005-124904, filed on Apr. 22, 2005 in the Japanese
Patent Office, the disclosure of which is incorporated herein in
its entirety by reference.
[0002] 1. Field of the Invention
[0003] The present invention relates to a digital camera wherein
a user can take a picture of an object by looking at a screen of
a display unit while holding the digital camera by hand.
[0004] 2. Description of the Related Art
[0005] Recently, for users' convenience, smaller and slimmer digital
cameras have been manufactured. Digital camera display units such
as liquid crystal displays (LCDs), however, are required to be large
to improve visibility of an image when determining a photograph
range during photographing, or checking or processing a photographed
image. Also, the size of a user grip of a miniaturized slim digital
camera inevitably becomes small and, thus, the user cannot stably
support the digital camera when photographing. Therefore, a small
and slim digital camera with an improved grip is required.
[0006] Japanese Patent Laid-Open Publication No. 2004-309740 discloses
a digital camera having a rotatable grip, of the same thickness
as the main body of the digital camera, separately mounted on a
side of the main body. Thus, the grip can protrude further outward
than the main body by rotating the grip. As a result, a user can
hold the grip, and take a photograph of an object while the digital
camera is in a stable state. Also, the digital camera can be slim,
since the grip can be disposed so that it does not protrude from
the main body when not photographing. Although this digital camera
provides an improved grip, a separate grip having the same thickness
as the main body of the digital camera is required. Therefore, such
a digital camera has an undesirable increased width.
[0007] Japanese Patent Laid-Open Publication No. 2004-266694 discloses
a digital camera having a main body of the digital camera, a rotation
axis formed at the rear of the main body and that coincides with
an optical axis, and a display cabinet (display unit) that is rotatably
coupled to the main body to be able to rotate with respect to the
rotation axis. Thus, a user can rotate the display cabinet to place
it in a location convenient for the user to see the display cabinet.
In such a digital camera, the display cabinet can be rotated with
respect to the main body of the digital camera and the main body
protruding by the rotation of the display cabinet can be used as
the grip. This digital camera, however, is not as stable as desired.
SUMMARY OF THE INVENTION
[0008] The present invention provides a small and slim digital
camera with an improved grip and a large display unit.
[0009] According to an aspect of the present invention, there is
provided a digital camera comprising a case including a main body
in which a lens unit is formed on a front surface of the main body;
a side portion of the case that is pivotably coupled to the main
body to be able to pivot toward the lens unit with respect to the
main body; and a manipulating unit that is exposed to the outside
between the main body and the side portion at a rear surface of
the case when the side portion is pivoted.
[0010] Because the side portion of the case is pivotable toward
the lens unit, a user may pivot and hold the side portion during
photographing, using the extended side portion as a grip. In addition,
since the side portion is pivoted toward the lens unit, a contact
area between the palm of the user holding the side portion and an
outer surface of the side portion is greatly increased.
[0011] Moreover, the manipulating unit between the main body and
the side portion is exposed to the outside at the rear surface of
the case when the other side is pivoted. The manipulating unit can
be accommodated in the case as the other side returns to its original
location.

DETAILED DESCRIPTION OF THE INVENTION
[0022] The present invention will now be described more fully with
reference to the accompanying drawings, in which exemplary embodiments
of the invention are shown.
[0023] Referring to FIGS. 1 and 2, a digital camera A according
to an embodiment of the present invention includes a case 1, a lens
unit 2, and a display unit 3. The display unit 3 can be, for example,
a flat panel display (FPD). The case 1 is shaped substantially like
a hexahedron and forms the exterior of the digital camera A. The
lens unit 2 is installed in a front surface 1a of the case 1 to
obtain an image of an object. The display unit 3 is installed in
a rear surface 1b of the case 1.
[0024] Referring to FIGS. 1 thorough 3, the case 1 includes a first
case unit 4, a second case unit (i.e., a side portion) 5, and a
hinge unit 6. The second case unit 5 is installed at one side of
the case 1. The hinge unit 6 is installed near the front surface
1a of the case 1 at the border between the first and second case
units 4 and 5. The hinge unit 6 contacts the first case unit 4 so
that the second case unit 5 can be pivoted.
[0025] As illustrated in FIG. 3, the first case unit 4 includes
a main body 7, protrusion unit 8, the lens unit 2 installed in the
front surface 7a of the main body 7, and the display unit 3 shaped
in a rectangular flat panel and that is installed in a rear surface
7b of the main body 7. The main body 7 is formed substantially like
a hexahedron. The protrusion unit 8 is formed on a side surface
7e of the main body 7 that is closer to the second case unit 5.
[0026] The protrusion unit 8 protrudes in a direction perpendicular
to the side surface 7e of the main body 7 that is closer to the
second case unit 5. A cross section of the protrusion unit 8 is
shaped like a fan. The protrusion unit 8 includes a flat side surface
8a, a curved side surface 8b, and top and bottom surfaces 8c and
8d covering the top and bottom ends of the flat and curved side
surfaces 8a and 8b. The flat side surface 8a is disposed close to
the front surface 7a of the main body 7 along the direction in which
the protrusion unit 8 extends. The curved side surface 8b, which
connects the side surface 7e of the main body 7 and the flat side
surface 8a, is curved like an arc with an axis 01 of the hinge unit
6 as its center.
[0027] The flat side surface 8a is disposed closer to the front
surface 7a of the main body 7 than the rear surface 7b of the main
body 7. A part of the curved side surface 8b contacting the side
surface 7e of the main body 7 is disposed closer to the rear surface
7b of the main body than the front surface 7a of the main body 7.
The top and bottom surfaces 8c and 8d are parallel to the top and
bottom surfaces 7c and 7d of the main body 7. The top surface 8c
of the protrusion unit 8 is disposed closer to the top surface 7c
of the main body 7 than the bottom surface 7c of the main body,
and the bottom surface 8d of the protrusion unit 8 is disposed closer
to the bottom surface 7d of the main body 7 than the top surface
7c of the main body 7.
[0028] The second case unit 5, shaped substantially like a hexahedron,
includes a side surface 5a that is close to the first case unit
4. An aperture 5b is formed in the side surface 5a. A groove 5e
is formed in a corner 5d where the side surface 5a and a front surface
5c of the second case unit 5 meet. The cross section of the groove
5e is concave. The radius of the groove 5e is equal to the radius
of first, second, and third cylindrical members 6a, 6b, and 6c of
the hinge unit 6, which will be described later.
[0029] The hinge unit 6 includes two protruding pieces 6d and 6e,
an axis rod 6f shaped like a cylindrical rod, and the three cylindrical
elements 6a, 6b, and 6c, as illustrated in FIGS. 2 and 3. The protruding
pieces 6d and 6e are perpendicularly formed on the side surface
7e of the main body 7 to protrude toward the second case unit 5.
The protruding pieces 6d and 6e are flat and their outer circumferences
are shaped like circular arcs, and communicating holes 6g are respectively
formed in each of the protruding pieces 6d and 6e. The axis rode
6f passes through the protruding pieces 6d and 6e. The protruding
pieces 6d and 6e are disposed near the front surface 7a of the main
body 7, and parallelly extend respectively from the top and bottom
surfaces 7c and 7d of the main body 7. The axis rod 6f is inserted
into the first, second, and third cylindrical members 6a, 6b, and
6c, and is fixed when a top end 6h and a bottom end 6i of the axis
rod 6f are respectively inserted into the protruding pieces 6d and
6e.
[0030] One of the cylindrical members (e.g., the first cylindrical
member 6a) among the three cylindrical members 6a, 6b, and 6c is
disposed roughly at the center of the height of the bottom surface
7d of the main body 7, and the outer circumferential surface of
the one of the cylindrical members is integrated with the main body
7. The outer circumferential surfaces of the other two cylindrical
members (e.g., the second and third cylindrical members 6b and 6c)
are integrated with the groove 5e of the second case unit 5. The
first and second case units 4 and 5 are connected by inserting the
axis rod 6f into the first, second, and third cylindrical members
6a, 6b, and 6c. At the same time, the second cylindrical member
6b is disposed above the first cylindrical member 6a and the third
cylindrical member 6c is disposed below the first cylindrical member
6a to support the second case unit 5.
[0031] In the above-described structure, the second case unit 5
can pivot with respect to the axis 01 of the hinge unit 6 (i.e.,
the axis of the axis rod 6f); that is, the second case unit 5 can
be pivoted toward the lens unit 2 in the first case unit 4 since
the hinge unit 6 is disposed near the front surface 1a of the case
1. When the second case unit 5 is not pivoted, the side surface
5a of the second case unit 5 in which the aperture 5b is formed
contacts the side surface 7e of the main body 7 near the second
case unit 5 so that the second case unit 5 is aligned with the main
body 7 of the first case unit 4. The protrusion unit 8 can be accommodated
in the aperture 5b of the second case unit 5 because the width and
height of the protrusion unit 8 is slightly smaller than the width
and height of the main body 7. When the second case unit 5 is pivoted,
an end 5f of the side surface 5a of the second case unit 5 facing
the hinge unit 6 pivots with respect to the axis 01 of the hinge
unit 6, and thus the second case unit 5 is pivoted in a circular
line without contacting the curved side surface 8b of the protrusion
unit 8.
[0032] A cylindrical power supply button 10 that can be pushed
in a direction perpendicular to the side surface 7e is formed on
the side surface 7a of the main body 7 near the second case unit
5. The power supply button 10 acts as a detecting element 13 (see
FIG. 6) that detects whether the second case unit 5 is pivoted.
The detecting element 13 detects that the power supply button 10
is pushed into the main body 7 and transmits a signal to a switching
element 15 (see FIG. 6), which will be described later, based on
the detected results to turn off a power supply unit of the digital
camera A. Conversely, when the power supply button 10 is protruded
from the side surface 7e, the detecting element 13 detects the power
supplying button 10 protruding outward and transmits a signal to
the switching element 15 to turn on the power supply unit. Therefore,
the power supply button 10 can turn on or off the power supply unit.
[0033] A manipulating unit 11 is provided at the protrusion unit
8. The manipulating unit 11 includes zoom buttons 11a, setting buttons
11b, and a recording medium inserting unit 11c in which a rectangular
aperture is formed. The zoom buttons 11a used during photographing
and the setting buttons 11b for setting various settings are disposed
near the main body 7 on the curved side surface 8b. The recording
medium inserting unit 11c for installing a recording medium therein
is formed in the curved side surface 8b near the flat side surface
8a.
[0034] The manipulating unit 11 also includes a shutter release
button 11d formed on top of the top surface 8c of the protrusion
unit 8 and a groove 12 (see FIGS. 4 and 5) formed on the bottom
surface 8d of the protrusion unit 8. The shutter release button
11d protrudes in a direction perpendicular to the top surface 8c.
The groove 12 is made along the circumference of the curved side
surface 8b, and first, second, and third hemispherical indents 12a,
12b, and 12c are lined in the groove 12 at fixed intervals. The
first, second, and third hemispherical indents 12a, 12b, and 12c
are sequentially lined from near the first case unit 4 to the second
case unit 5. The second and third hemispherical indents 12b and
12 act as the detecting element 13 that detects to which step the
second case unit 5 is pivoted. When a hemispherical protrusion 14d
is coupled to one of the first, second, and third hemispherical
indents 12a, 12b, and 12c, an electrical signal, for example, is
generated and, based on the detection results of the electrical
signal, a signal is transmitted to the switching element 15 to turn
on or off the system power of the digital camera A.
[0035] As illustrated in FIGS. 3 through 5, a plate element 14
is fixed on a top surface 5i of a bottom surface 5g of the second
case unit 5. The plate element 14 includes an oval shaped portion
14b in which two holes 17e are formed, and a protruded portion 14c,
which extends from a circular circumference of the oval shaped portion
14b.
[0036] The hemispherical protrusion 14d protruding in a direction
perpendicular to a top surface of the protruded portion 14c is formed
on top of an end of the protruded portion 14c that is further away
from the oval shaped portion 14b. The plate element 14 is fixed
to the bottom surface 5g of the second case unit 5 via a pin 14e
inserted into one of the holes 14. The other hole 17e is disposed
in line with the third cylindrical member 6c of the hinge unit 6
and the protruding piece 6e that parallelly extends from the bottom
surface 7d of the main body 7, and the axis rod 6f is inserted in
the hole 17e. The hemispherical protrusion 14d is disposed above
the top surface 5i of the bottom surface 5g. Thus, when the first
case unit 4 and the second case unit 5 are coupled to each other
via the hinge unit 6, the hemispherical protrusion 14d is coupled
to the groove 12 formed in the bottom surface 8d of the protrusion
unit 8 of the first case unit 4.
[0037] Referring to FIG. 6, in the digital camera A according to
the present embodiment, the lens unit 2 includes a zoom lens for
controlling magnification of an object, an iris for controlling
the size of an aperture control, and a focus lens for controlling
focus of the object. Motors 20, which respectively control the zoom
lens, the iris, and the focus lens, are connected to motor drivers
21 inside the first case unit 4 to perform focus, aperture, and
magnification adjustments of the digital camera A.
[0038] A charged coupled device (CCD) 22, which focuses an image
of the object obtained, is connected to the lens unit. The CCD 22
is connected to an analog-to-digital (A/D) converter 23 via a correlated
double sampling (CDS) amplifier AMP 24. The A/D converter 23 converts
an analog signal of the obtained image into a digital signal, and
the CDS-AMP 24 removes noise included in the analog signal output
from the CCD 22; then amplifies the analog signal. The A/D converter
23 is connected to an image signal processor 25. The image signal
processor 25 receives the digital signal of the image from the A/D
converter 23, performs color temperature compensation, gamma compensation,
edge enhancement, etc., on the image, converts a resolution of image
data into a preset resolution, and compresses and encodes the image
data.
[0039] The image signal processor 25 is connected to a first central
processing unit (CPU) 26, a synchronous dynamic random access memory
(SDRAM) 27, and a video random access memory (VRAM) 28 via a bus
line 29 in a motherboard. The display unit 3 is also connected to
the bus line 29 via a liquid crystal display (LCD) driver 30, and
a recording medium 23 is connected to the bus line 29 via a media
controller 31.
[0040] The first CPU 26 is connected to each of the motor drivers
21, a timing generator 33, and the CDS-AMP 24. The first CPU 26
controls each of the motor drivers 21, the timing generator 33,
and the CDS-AMP 24 based on, for example, various processes performed
by the image signal processor 25. The timing generator 33 is connected
to the CCD 22 to generate various horizontal or vertical driving
signals to drive the CCD 22 or signals used in analog front processing
in synchronization with a reference clock.
[0041] A second CPU 34 is connected to the first CPU 26. The detecting
element 13 of the power supply button 10 or the hemispherical indents
12b and 12c, the switching element 15, and the manipulating unit
11 provided in the protrusion unit 8 illustrated in FIGS. 3 through
5 are connected to the second CPU 34. The second CPU 34 receives
an output signal from the manipulating unit 11 to control various
operations together with the first CPU 26. Also, the second CPU
34 receives an output signal from the detecting element 13 to control
switching of the power supply unit of the digital camera A from
on to off or vice versa.
[0042] The operation and effects of the digital camera A constructed
as above will now be described.
[0043] First, when the digital camera A does not perform photographing,
the side surface 7e of the main body 7 near the second case unit
5 and the side surface 5a of the second case unit 5 in which the
aperture 5b is formed contact each other, as illustrated in FIGS.
1 through 3. In the present state, the protrusion unit 8 on which
the manipulating unit 11 is formed is accommodated in the second
case unit 5. As a result, the digital camera A can be maintained
in a small and slim state. The side surface 5a of the second case
unit 5 pushes the power supply button 10 formed on the side surface
7e of the main body 7 into the first case unit 4 and, thus, the
power supply unit of the digital camera A is turned off. Also, in
the present state, the hemispherical protrusion 14d of the plate
element 14 installed in the second case unit 5 is inserted into
the first hemispherical indent 12a.
[0044] When the user uses the digital camera A to take a picture
of an object, the user holds the digital camera A by the second
case unit 5 with his or her hand 35 and pivots the second case unit
5 with respect to the axis 01 of the hinge unit 6, as illustrated
in FIG. 7. By pivoting the second case unit 5, the hemispherical
protrusion 14d of the plate element 14 is released from the first
hemispherical indent 17e and moves along the groove 12 so that the
second case unit 5 moves toward the lens unit 2. As the second case
unit 5 is pivoted, the side surface 5a of the second case unit 5
simultaneously moves away from the side surface 7e of the main body
7. As a result, the power supply button 10 is no longer pushed into
the first case unit 4, and an output signal regarding the current
release of the power supply button 10 is transmitted to the second
CPU 34. Thereafter, the second CPU 34 transmits a signal to the
switching element 15 to turn on the power supply unit of the digital
camera A. When the hemispherical protrusion 14d, which moves along
the groove 12 by the pivoting operation of the second case unit
5, is inserted into the second hemispherical indent 12b, the first
step of the pivoting operation of the second case unit 5 is completed.
[0045] In the present embodiment, the shutter release button 11d,
the zoom buttons 11a, and the setting buttons 11b of the manipulating
unit 11 disposed on the curved side surface 8b of the protrusion
unit 8, which are required for photography an image, are exposed
to the outside between the main body 7 of the first case unit 4
and the second case unit 5 at the rear surface 1b of the case 1,
as illustrated in FIG. 7.
[0046] The user takes a photograph of an object by directing the
front surface 1a of the case 1 toward the object while holding the
digital camera A by the second case unit 5 pivoted toward the lens
unit 2 with his or her hand 35. Since the second case unit 5 is
pivoted toward the lens unit 2, the user touches a larger area of
an outer surface 5j of the second case unit 5. Also, the user can
operate the manipulating unit 11, such as the shutter button 11d,
the zoom buttons 11a, or the setting buttons 11b, using his or her
index finger 35a or thumb 35b while holding the digital camera A
by the second case unit 5.
[0047] As illustrated in FIG. 6, a signal output when the user
manipulates, for example, the shutter release button 11d is transmitted
to the second CPU 34, and the second CPU 34 transmits an operating
order to the motor 20 via the first CPU 26 and the motor driver
21. Accordingly, the magnification, focus, or aperture adjustment
is performed, then an image of the object is obtained. The image
of the object is focused in the CCD 22, and an analog signal of
the focused image is converted into a digital signal via the A/D
converter 23 and transmitted to the image signal processor 25. The
image signal processor 25 performs various processes and transmits
the digital signal to the display unit 3 via the LCD driver 30 to
display an image on the display unit 3. User confirms the image
displayed and memorizes the displayed image to a recording medium
32 via a media controller 31.
[0048] When the second case unit 5 is pivoted further toward the
lens unit 2 as illustrated in FIGS. 3 through 6, the hemispherical
protrusion 14d inserted into the second hemispherical indent 12b
is released as the second case unit 5 is pivoted and moves along
the groove to be inserted into the third hemispherical indent 12c.
In the current state, the second step of the pivoting operation
of the second case unit 5 is completed.
[0049] In the present embodiment, the recording medium inserting
unit 11c is exposed to the outside as the second case unit 5 is
pivoted from the first step to the second step. The power supply
unit of the digital camera A should be off when the recording medium
32 is inserted in or removed from the recording medium inserting
unit 11c. Therefore, when the semis spherical protrusion 14d is
inserted into the third hemispherical indent 12c, the detecting
element 13 outputs a signal to the second CPU 34. Thereafter, the
second CPU 34 transmits a command to the switching element 15 to
turn off the power supply unit of the digital camera A. Thus, the
power supply unit of the digital camera A is automatically turned
off when the user pivots the second case unit 5 to the second step
to insert or remove the recording medium 32 to or from the recording
medium inserting unit 11c.
[0050] When the second case unit 5 is pivoted from the second step
to the first step, the detecting element 13 detects the hemispherical
protrusion 14d inserted into the second hemispherical indent 12b
and, consequently, the power supply unit of the digital camera A
is turned on. Also, as the second case unit 5 is pivoted from the
first step to a state in which the side surface 5a of the second
case unit 5 contacts the side surface 7e of the main body 7, the
power supply button 10 is once again pushed into the first case
unit 4, thereby turning off the power supply unit of the digital
camera A.
[0051] Therefore, in the digital camera A constructed as above,
because the second case unit 5 can be pivoted toward the lens unit
2 with respect to the axis 01 of the hinge unit 6, the second case
unit 5 can be used to hold the digital camera A when photographing
an object and, at the same time, greatly increase the contact area
between the palm of the user holding the second case unit 2 and
the outer surface of the second case unit 5. As a result, the digital
camera A can be stably supported while photographing an object.
[0052] When the second case unit 5 is not pivoted, the second case
unit 5 is aligned with the case 1 of the digital camera A. The protrusion
unit 8 in which the manipulating unit 11 is formed is accommodated
inside the second case unit 5 and, thus, the digital camera A is
maintained in a small and slim state.
[0053] The components of the manipulating unit 11 can be sequentially
exposed to the outside as the second case unit 5 pivots from the
first step to the second step and the exposure range of the manipulating
unit can be determined depending on the pivoting step. As a result,
at least a portion of the manipulating unit 11 does not need to
be formed on an outer surface of the case 1 and exposed to the outside
and, thus, the area occupied by the operating unit 11 on the outer
surface of the case 1 can be decreased. Consequently, the size of
the display unit can be increased.
[0054] As the second case unit 5 is pivoted, the power supply unit
of the digital camera A is simultaneously automatically turned on
or off by the power supply button 10. In addition, since the power
supply unit of the digital camera A can be automatically turned
on or off depending on the step to which the second case unit 5
is pivoted, the convenience of using the digital camera A increases.
[0055] While the present invention has been particularly shown
and described with reference to exemplary embodiments thereof, it
will be understood by those of ordinary skill in the art that various
changes in form and detail may be made therein without departing
from the spirit and scope of the present invention as defined by
the following claims. For example, although the second case unit
5 is pivoted to two steps in the embodiment described above, the
second case unit 5 can be pivoted to more than two steps. Also,
the pivoting operation of the second case unit 5 can be pivoted
without going through a special step, and when the second case unit
5 is pivoted in multiple steps, the second case unit 5 need not
be structured to include the groove 12 and the hemispherical protrusion
14d that is inserted into the first through third hemispherical
indents 12a through 12c arranged in a single line in the groove
12.
[0056] Also, in the embodiments of the present invention described
above, the components of the manipulating unit 11 used for photographing
an object are exposed to the outside when the second case unit 5
is pivoted to the first step and the recording medium inserting
unit 11c in or from which the recording medium 32 is inserted or
removed is exposed to the outside when the second case unit 5 is
pivoted to the second step. The types or number of components of
the manipulating unit 11 that are exposed to the outside as the
second case unit 5 is pivoted, however, need not be limited to the
above description. Also, in the digital camera A, other manipulating
elements that are always exposed to the outside in addition to,
the ones that are exposed to the outside by the pivoting operation
of the second case unit 5, may be installed on the first case unit
4 or the second case unit 4. Related to this, referring to FIG.
9, buttons 11e exposed to the outside are formed on the outer surface
of the second case unit 5 to perform various operations of the digital
camera A by pressing them while the side surface 5a of the second
case unit 5 and the sides surface 7e of the main body 7 contact
each other. For example, the power supply unit of the digital camera
A can be turned on or off, an image that was photographed can be
displayed on the display unit 3, or the displayed image can be processed.
The display unit 3 or a light-emitting element such as a light-emitting
diode (LED) for checking access of the recording medium 32 may be
exposed to the outside by the pivoting operation of the second case
unit 5, in addition to the manipulating unit 11. In this case, as
the display unit 3 or the light-emitting element is exposed to the
outside, an image can be simultaneously displayed on the display
unit 3 or the light-emitting element may be lit.
[0057] Regarding the structure of the digital camera A in which
the power supply unit is automatically turned on or off depending
on the step to which the second case unit 5 is pivoted, the detecting
element 13 need not be limited to the power supply button 10 and
the first, second, and third hemispherical indents 12a, 12b, and
12c. For example, a sensor that senses the pivoted angle of the
second case unit 5 may be installed in the digital camera A to detect
the pivoted angle of the second case unit 5 and turn the power supply
unit on or off by the switching element 15 based on the sensed result.
[0058] According to the embodiments of the present invention described
above, the image of the object obtained using the digital camera
A is a still image. The image, however, may also be a moving picture.
[0059] According to the digital camera of the present invention,
a side portion of the case that is pivoted when photographing an
object can be used as a grip. Also, since the side portion of the
case is pivoted toward a lens unit, a contact area between a palm
of a user and an outer surface of the side portion of the case is
increased and, thus, the digital camera can be stably supported
when photographing the object.
[0060] In addition, a manipulating unit is exposed to the outside
by the pivoting operation of the side portion of the case and the
manipulating unit is accommodated inside the side portion of the
case by pivoting the side portion of the case backward. As a result,
an area occupied by the manipulating unit that is formed on an outer
surface of the case is reduced and, thus, the digital camera can
be maintained in a small and slim state. Further, the size of the
display unit can be increased. |
