The relative positional relationship between the FPC board 60 and the
Does not change as it moves back and forth, so that the guide rollers 68, 69 do not need to rotate and may be fixed rollers. Alternatively, the folding guide 65 may be composed of a structure other than a roller. When the shutter block 23 moves back and forth, the position of the movable turnback portion 60b changes back and forth. The protruding portion of the FPC board 60 from the rear portion of the FPC guide plate 63 is drawn to extend rearward in FIGS. 1 and 2, but in reality, the FPC board 6 is guided to the front side of the camera body.
It can be bent forward along the bending guide 70 of 0.

内において確実にガイドされる。When the zoom motor 5 is driven in the camera of the above configuration,
The cam ring 14 rotates, and the advancing / retreating lens barrels 16 and 18 move in the optical axis direction in accordance with the cam grooves 20 and 21 to perform zooming and macro photography. Along with the movement of the advancing / retreating lens barrel 16, the shutter block 23 mounted therein also moves in the optical axis direction. Therefore, the FPC board 60 having the connection pattern 61 connected and fixed to the shutter block 23 extends according to the movement of the shutter block 23, but this extension is performed only by the change in the position of the movable folding portion 60b. That is, the FPC board 60 has the connection pattern 62 at its rear end connected and fixed to the CPU of the camera body, and the intermediate portion is guided by the FPC guide plate 63. Since the fixed folded portion 60a is fixedly guided by the guide rollers 68 and 69, when the shutter block 23 moves and the position of the connection pattern 61 at the tip of the FPC board 60 changes, the position of the movable folded portion 60b. Only second
As shown in FIG. 4 and FIG. 4, it moves back and forth. Therefore
The FPC board 60 has an annular space 64 between the cam ring 14 and the decorative frame 22.
It is surely guided inside.

Face the gap between. Therefore, the light entering the lens system is
Reflection on the FPC board 60 may cause harmful internal reflection. To prevent this, the FPC board 60 has a fifth
As shown in the figure, it is desirable to stack the antireflection sheet 71 on the inner surface, that is, the surface on the optical axis side. The antireflection sheet 71 can be made of, for example, matte black paper or the like, and by stacking it on the FPC board 60, it is possible to reliably prevent internal reflection.

The viewfinder field is changed and the strobe irradiation angle (light intensity) is changed in conjunction with the change in the focal length of the. The zoom motor 5 is used as a power source for that purpose. A pinion 50 different from the pinion 7 is meshed with the gear gear member 15 of the cam ring 14, and a shaft 51 of the pinion 50 is extended to the rear of the base plate 6 and a reduction gear train 52 is provided at the rear end thereof. ing. The final gear 52a of the reduction gear train 52 meshes with the rack 53a of the cam plate 53. The cam plate 53 is slidable to the left and right, and the lower bent portion 53 at the rear end
A rack 53a is integrally provided at the tip (lower end) of b.
The reduction gear train 52 reduces the rotation of the gear gear member 15 to reduce the movement of the cam ring 14 and apply the reduced movement to the cam plate 53. The cam plate 53 has a variable magnification cam groove 55 for the finder device 8.
, Parallax correction cam groove 56, and strobe device 9
A strobe cam groove 57 is provided.

している。The lens system of the finder device 8 is basically composed of a fixed subject-side lens unit L3, an eyepiece lens unit L4, and a movable variable-magnification lens unit L5, and further includes a deflection prism P1 for macro photography. I have it. The variable-magnification lens unit L5 includes a photographing screen by a variable-magnification operation of the lens barrel block 1,
The field of view is matched with each other, and the deflection prism P1 advances on the optical axis only during macro photography to correct parallax in particular. That is, as described above, the parallax is unavoidable in the lens shutter type camera, and the amount becomes larger as the close-up shooting is performed. However, the camera of this embodiment is capable of macro shooting, and at this time, the parallax amount is increased. Since it becomes large, only in macro photography, a wedge-shaped deflection prism P1 having a thick lower portion and a thin upper portion is inserted into the optical path to bend the optical path downward so that a portion closer to the photographed portion can be observed.
