Digital Camera Patent Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application is claiming priority of Korean Patent
Application No. 10-2004-0025347, filed on Apr. 13, 2004, the content
of which is herein incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a mobile communication
terminal capable of easily photographing with a digital camera equipped
therein. More specifically, the invention relates to a mobile communication
terminal having two longitudinal pivoting parts provided by dividing
a terminal cover into two covers. One of the pivoting parts has
a limited pivoting range within an angle of about 90.degree. relative
to a terminal main body.
[0004] 2. Description of the Related Art
[0005] Mobile communication terminals according to the prior art,
like a cellular phone, a wireless communication terminal and a PDA
(Personal Digital Assistant), etc. comprise a folder-type mobile
communication terminal wherein a cover hinge-connected to a main
body thereof can be pivoted longitudinally, and a folder-rotating
type (which is also referred to as "rotary type") mobile
communication terminal wherein a cover hinge-connected to a main
body thereof can be pivoted longitudinally and, simultaneously,
rotated horizontally.
[0006] Meanwhile, many of mobile communication terminals that are
recently released have camera functions in addition to their inherent
communication functions according to a multi-function tendency of
the mobile communication terminal.
[0007] In a folder-rotating type mobile communication terminal
having a digital camera function, a camera lens of the digital camera
may be fixed to a side surface of the mobile communication terminal.
In the folder-rotating type mobile communication terminal, since
a terminal cover loading a terminal screen can be horizontally rotated
relative to a terminal main body, a user can take a photograph while
looking at an image of a subject for photography displayed on the
terminal screen even though a camera lens of the digital camera
is positioned to a side surface of the terminal.
[0008] FIG. 1 shows a folder-rotating type mobile communication
terminal with a digital camera equipped to a side surface thereof
according to the prior art. And FIG. 2 shows a state that a cover
of the mobile communication terminal shown in FIG. 1 is pivoted
longitudinally and thus opened, and then again horizontally rotated.
[0009] As shown in FIG. 1, the prior folder-rotating type mobile
communication terminal is constructed such that a terminal cover
20 covering a terminal main body 10 can be folded by pivoting longitudinally
relative to the terminal main body 10 with a pivoting hinge shaft
30, and at the same time can be horizontally rotated relative to
the terminal main body 10 with a rotating-hinge shaft 40. A digital
camera 50 is equipped to a side surface of a hinge part 12 of the
terminal main body.
[0010] FIG. 2 shows a state that a cover of the mobile communication
terminal is pivoted longitudinally and thus opened, and then again
horizontally rotated. The longitudinal pivoting of the terminal
cover 20 is achieved through the pivoting-hinge shaft 30 and the
horizontal rotating is made through the rotating-hinge shaft 40.
Meanwhile, in FIG. 2, a camera lens of the digital camera 50 is
positioned to take a photograph of a subject facing a paper surface
and, therefore, it cannot be seen from the FIG. 2.
[0011] As shown in FIG. 2, a user can take a photograph while identifying
an image of a subject for photography through a terminal screen
22 by rotating the terminal screen 22 horizontally to be faced in
a direction opposite to the lens of the camera lens.
[0012] In this case, the pivoting-hinge shaft 30 is connected to
the terminal main body 10 by a first hinge body 32 to be pivoted
longitudinally. And the terminal cover 20 is connected to the pivoting-hinge
shaft 30 by a second hinge body 42 to be rotated horizontally.
[0013] Meanwhile, the mobile communication terminal of the prior
folder-rotating type as shown in FIG. 2 has a large angle between
the terminal cover 20 and the terminal main body 10 enough to a
telephone call.
[0014] Like this, when the terminal cover 20 is horizontally rotated
under state that the terminal cover 20 is opened to the large angle,
the terminal screen 22 is inclined at a certain angle, rather than
being horizontal or vertical relative to the terminal main body
10. Accordingly, it is difficult for a user to capture an erect
image of the subject for photography.
[0015] Needless to say, the terminal cover 20 and the terminal
main body 10 may be adjusted to be vertical when the terminal cover
20 is pivoted relative to the terminal main body 10 in the prior
mobile communication terminal. However, the attentiveness is required
to set the vertical state. In addition, the vertical state is apt
to be inclined since there is no a constituting element supporting
the vertical state, even after setting the vertical state.
[0016] Accordingly, if a user wishes to take a photograph by using
the prior folder-rotating mobile communication terminal having a
digital camera to a side surface thereof, a user should perform
the photography while putting up with the situation in which the
image displayed on the screen is seen to be inclined, otherwise
paying attention to adjust the cover to the vertical state and to
maintain the vertical state relative to the terminal main body.
SUMMARY OF THE INVENTION
[0017] Accordingly, the present invention has been made to solve
the above-mentioned problems occurring in the prior art. The object
of the present invention is to provide a folder-rotating type mobile
communication terminal having two longitudinal pivoting parts provided
by separating a terminal cover into two covers and thus being capable
of easily capturing an erect image of a subject for photography
even though a digital camera is equipped to a side surface of a
terminal main body.
[0018] In order to accomplish the objects, there is provided a
mobile communication terminal comprising a terminal main body; a
first terminal cover hinge-connected to the terminal main body and
pivoting longitudinally relative to the terminal main body; a connecting
shaft hinge-connected to the first terminal cover and pivoting longitudinally
relative to the first terminal cover; and a second terminal cover
connected to the connecting shaft so as to horizontally rotate relative
to the connecting shaft and provided with a terminal screen on a
surface facing the terminal main body.
[0019] Preferably, if the first terminal cover is pivoted to an
angle of about 90.degree. relative to the terminal main body, it
is prevented from being further pivoted.
[0020] Meanwhile, it is preferred that a limiting protrusion, which
is contacts with an upper end of the terminal main body when the
first terminal cover is pivoted to the angle of about 90.degree.
relative to the terminal main body, is formed on a rear surface
of the first terminal cover as the means for limiting the pivoting
of the first terminal cover.
[0021] According to the invention, it is preferred that the digital
camera is mounted to one of a side surface of the first terminal
cover, a side surface of the terminal main body and a front surface
of the second terminal cover.
[0022] According to the invention, it is preferred that if the
digital camera is provided to the side surface of the first terminal
cover, an extension part for mounting the digital camera is formed
protrudingly on a top of the first terminal cover.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0032] Hereinafter, preferred embodiments of the present invention
will be described with reference to the accompanying drawings. In
the following description of the present invention, a detailed description
of known functions and configurations incorporated herein will be
omitted when it may make the subject matter of the present invention
rather unclear.
[0033] FIG. 3 shows a state that components of a mobile communication
terminal according to an embodiment of the invention are disassembled,
and FIG. 4 shows two side views of a state that a mobile communication
terminal of which cover is closed according to an embodiment of
the invention.
[0034] As shown in FIGS. 3 and 4, a mobile communication terminal
according to an embodiment of the invention comprises a terminal
main body 100, a first terminal cover 200, a connecting shaft 300
and a second terminal cover 400.
[0035] The first terminal cover 200 is connected to the terminal
main body 100 to be pivoted longitudinally relative to the terminal
main body 100. The connecting shaft 300 is connected to the first
terminal cover 200 so that it can be pivoted longitudinally. The
second terminal cover 400 is connected to the connecting shaft 300
so that it can be horizontally rotated.
[0036] Hereinafter, each of the components will be described specifically.
[0037] The terminal main body 100 is provided with various input
keys typically. Hinge parts 120 for connecting to the first terminal
cover 200 are formed at both upper sides of the terminal main body
100.
[0038] The first terminal cover 200 is provided with a protrusion
part 210 on a rear surface thereof to be connected to both the hinge
parts 120 of the terminal main body 100. The protrusion part 210
is provided with a first pivoting hinge shaft 220. The first pivoting
hinge shaft 220 is inserted into a recess 121 formed in the hinge
part 120 of the terminal main body 100, so that the first terminal
cover 200 can be pivoted relative to the terminal main body 100.
[0039] In addition, the first terminal cover 200 is provided with
hinge parts 230 at both lower sides thereof in which a recess 231
is formed.
[0040] It is preferred that the first terminal cover 200 can be
opened up to an angle of about 90.degree. relative to the terminal
main body 100. To this end, the first terminal cover 200 is provided
with a limiting protrusion 201 on the rear surface thereof, which
contacts with an upper surface 101 of the terminal main body 100
when the first terminal cover 200 is pivoted to an angle of about
90.degree., and thus prevents the first terminal cover 200 from
being further pivoted.
[0041] The connecting shaft 300 is connected to the both hinge
parts 230 formed in the first terminal cover 200 so as to be pivoted
relative to the first terminal cover 200. To this end, the connecting
shaft 300 is provided a second pivoting hinge shaft 310. The second
pivoting hinge shaft 310 is inserted into the recess 231 formed
in the hinge part 230 and thus performs a hinge-function.
[0042] In addition, a rotating hinge shaft 320 is formed in a middle
of the connecting shaft 300.
[0043] A terminal screen 410 is mounted to an inner surface of
the second terminal cover 400, which faces the terminal main body
100 during the state that the mobile communication terminal is not
used. The second terminal cover 400 may be rotated horizontally
relative to the connecting shaft 300 owing to be connected to the
rotating hinge shaft 320 formed in the middle of the connecting
shaft 300.
[0044] A digital camera 50 may be mounted to one of a side surface
of the terminal main body 100, a side surface of the first terminal
cover 200 and a front surface of the second terminal cover 400 (i.e.,
an opposite surface of the terminal screen 410). The embodiments
shown in FIG. 3 and FIG. 4 are the cases in point that the digital
camera 50 is provided to the side surface of the first terminal
cover 200. To this end, an extension part 240 for mounting the digital
camera 50 is formed on a top of the first terminal cover 200. In
case that the digital camera 50 is mounted to a side surface of
the terminal main body 100 or a front surface of the second terminal
cover 400, it does not need to form the extension part 240.
[0045] Meanwhile, we consider the case that the digital camera
50 is mounted to the front surface (an opposite surface of the terminal
screen 410) of the second terminal cover 400. In this case, if a
user maintains the horizontal state of the terminal main body 100
after pivoting the first terminal cover 400 to an angle of about
90.degree. relative to the terminal main body 100, the user may
be easily capture an erect image of a shape of a subject for photography
through the terminal screen 410.
[0046] In this case, the terminal screen 410 faces straightly (vertically)
to a user, and the digital camera 50 captures a subject for photography
which is in a same direction as the user looks at.
[0047] FIGS. 5 to 8 show using states of the mobile communication
terminal according to an embodiment of the invention in case that
the digital camera 50 is mounted to the side surface of the first
terminal cover 200. The using states of the mobile communication
terminal shown in FIGS. 5 to 8 may also be applicable to the case
that the digital camera 50 is mounted to the side surface of the
terminal main body 100.
[0048] An operation of the mobile communication terminal will be
described with reference to FIGS. 5 and 6.
[0049] When it is taken a photograph using the digital camera 50
mounted to the side surface of the terminal main body 100, the first
and second terminal covers 200, 400 may be pivoted upwardly relative
to the terminal main body 100 firstly. In this case, when the first
terminal cover 200 is pivoted to an angle of about 90.degree. relative
to the terminal main body 100, the limiting protrusion 201 (see
FIG. 3) formed on the rear surface of the first terminal cover 200
contacts with the upper end 101 of the terminal main body 100. As
a result, the first terminal cover 200 cannot be further pivoted,
so that it stops pivoting under a state of being opened to the angle
of about 90.degree..
[0050] Under these conditions, as shown in FIG. 6, if a user rotates
the second terminal cover 400 horizontally relative to the connecting
shaft 300, the terminal screen 410 of the second terminal cover
400 faces to the user.
[0051] Thus, the second terminal cover 400 maintains its vertical
state relative to the terminal main body 100 and the terminal screen
400 faces toward the exact opposite to a camera lens of the digital
camera 50 and, therefore, the user may take a photograph with capturing
an erect image of a subject for photography easily. In addition,
the user may precisely perform a zooming or composing operation
for the subject.
[0052] Meanwhile, if a user wishes to make a telephone call with
the mobile communication terminal of the invention, it just needs
pivoting the second terminal cover 400 to a further upward position
to be suitable for the call from the state as shown in FIG. 5. That
is, by pivoting the second terminal cover 400 and the connecting
shaft 300 upwardly relative to the first terminal cover 200 secondarily,
the second terminal cover 400 achieves a suitable angle for the
telephone call relative to the terminal main body 100 as shown in
FIG. 7.
[0053] A technical composition which limits pivot angle between
a terminal cover and a terminal main body in the prior folder-rotating
type mobile communication terminal may also be applicable to the
mobile communication terminal of the invention in order to achieve
the suitable angle for the telephone call between the second terminal
cover 400 and the terminal main body 100.
[0054] FIG. 7 shows that the connecting shaft and the second terminal
cover of the mobile communication terminal shown in FIG. 5 are pivoted
upwardly relative to the first terminal cover secondarily, and FIG.
8 shows that the second terminal cover of the mobile communication
terminal shown in FIG. 7 is horizontally rotated.
[0055] As shown in FIG. 8, the mobile communication terminal of
the invention may also take a photograph even if the second terminal
cover 400 is completely pivoted relative to the terminal main body
100. In this case, since the second terminal cover 400 has an inclined
angle instead of vertical angle relative to the terminal main body
100, the mobile communication terminal takes a photograph under
a state that the terminal screen 410 is inclined like the prior
art.
[0056] The mobile communication terminal may reach to a state shown
in FIG. 8 by either pivoting the connecting shaft 300 upwardly relative
to the first terminal cover 200 secondarily from the mobile communication
terminal shown in FIG. 6 or rotating the second terminal cover 400
horizontally relative to the connecting shaft 300 from the mobile
communication terminal shown in FIG. 7.
[0057] As described above, the folder-rotating type mobile communication
terminal of the invention has two longitudinal pivoting parts by
dividing the terminal cover into two covers. A pivot angle of one
of the pivoting parts may be limited to less than about 90.degree.
relative to the terminal main body.
[0058] Thus, according to the invention, since it is possible to
easily control and maintain the terminal screen to the angle of
about 90.degree. relative to the main body, a user can easily capture
an erect image of a subject for photography even if the digital
camera is provided to the side surface of the terminal main body.
[0059] While the invention has been shown and described with reference
to certain preferred embodiments thereof, it will be understood
by those skilled in the art that various changes in form and details
may be made therein without departing from the spirit and scope
of the invention as defined by the appended claims. |
