arranged to the back surface perpendicular to the optical axis O
of the fixing frame 41.
[0056] The LCD display unit 11 has an LCD which displays the picked-up
image or various information data, and is adhered by a both-side
adhesive tape and is fixed to the back surface of the unit attaching
plate 48 while the LCD display surface is perpendicular to the optical
axis O and is directed to the back. The LCD display unit 11 is partly
projected in the side direction of the back of the fixing frame
41 of the lens barrel 3 in the fixing state.
[0057] Another part of the image pickup circuit and a connector
62 for connection to the electric substrate (B)7 are mounted on
the image pickup substrate 10, and are connected to the CCD substrate
9 via a flexible printed board 47. The image pickup substrate 10
is positioned in the space sandwiched by the projected portion of
the lens driving unit 13 and the left projected portion of the fixing
frame 41 of the LCD display unit 11, and is fixed and supported
to the fixing frame 41 with the principal plane thereof in parallel
with the optical axis O and with the longitudinal direction thereof
along the vertical (up/down) direction.
[0058] As mentioned above, in the assembling unit 70 around the
lens barrel, the image pickup substrate 10, the unit attaching plate
48, and the LCD display unit 11 are assembled, as a unit, to the
fixing frame 41 of the lens barrel 3 to which the lens driving unit
13 and the CCD substrate 9 are attached.
[0059] Upon assembling the components of the camera 1 to the camera
case 2 of the camera 1, referring to FIG. 4, the strobe light-emitting
unit 5 is adhered and fixed into the inner surface of the front-cover
unit 2A. Further, the lens barrier 15 is inserted in the guide groove
22a and is slidably attached.
[0060] The assembling unit 70 around the lens barrel, as a unit,
is attached, via the unit attaching plate 48, to the middle frame
24 to which the electric substrates (A)6, (B)7 and (C)8 are fixed
and supported, and is assembled as a camera including block. That
is, a screw is inserted in the screw inserting hole 24b of the middle
frame 24 and another screw inserting hole (not shown). Further,
screws are screwed to the screw hole 48c of the upper bend projected
portion of the unit attaching plate 48 and the screw inserting hole
48d of the down left projected portion, thereby integrating the
middle frame 24 and the assembling unit 70 around the lens barrel.
The screw inserted in the screw inserting hole 8a arranged to the
DC terminal side of the electric substrate (C)8 is screwed to the
screw hole 48e of the unit attaching plate 48, and the end of the
electric substrate (C)8 is fixed to the unit attaching plate 48.
The connector 62 for connection of the image pickup substrate 10
is connected to the connection connector 61 of the electric substrate
(B)7. Further, a finder unit is attached and is fixed and supported
to the upper portion of the fixing frame 41 of the lens barrel 3.
[0061] Blocks incorporated in the camera including the electric
substrates and the assembling unit 70 around the lens barrel are
covered, sandwiching in the front-cover unit 2A and the back-cover
unit 2C. A screw (not shown) is inserted to the back-cover frame
26 and is screwed into a screw hole (not shown) of the front-cover
frame 22, thereby completing the camera 1.
[0062] In the camera assembling state, the front end of the fixing
frame 41 of the lens barrel 3 is fit and is attached to the inner
circumference of the front ring 31 attached to the front-cover unit
2A. The packing 44 arranged to the outer circumference of the fixing
frame 41 is modified into a U-shaped cross section and is inserted
to the inner circumference of the front ring 31, thereby setting
the fitting space between the lens barrel 3 and the front-cover
unit 2A to be watertight. The moving frame 42 of the inserted lens
barrel 3 is fit to the opening 31a for taking lens of the front
ring 31 via a watertight packing (not shown), thereby being advanced/returned
at shooting positions projected in the front direction from the
collapsible mount position at which the shooting is impossible.
Further, when the moving frame 42 is at the collapsible mount position,
the front surfaces of the moving frame 42 and the taking lens 43
are covered by the lens barrier 15. When the lens barrier 15 is
slid at the releasing position for sheltering from the front surfaces
of the moving frame 42 and the taking lens 43, the moving frame
42 is automatically moved to the shooting position. When the lens
barrier 15 is at the closing position for covering the front surface
of the taking lens 43 and then the lens barrier 15 is pressed by
a user, the end of the lens barrier 15 comes into contact with the
projected portion 31b of the front ring 31, thereby preventing the
modification of the metallic thin-plate front-cover plate 21.
[0063] Here, a description is given of an arranging positional
relationship of components in the camera 1 in the assembling state
