略平行になるように配設されていた。Prior Art FIG. 7 shows a conventional disc camera IA, in which a disc-shaped film cartridge 4A is completely housed in a cartridge storage chamber 3A formed within the camera body 2A. The back cover, which forms the cartridge storage chamber 3A together with the camera body 2A, has a protruding claw (not shown) attached to the rear side (a). The back cover is locked in the closed position through the opening 6A, and the opening/closing operation section 7A of the exposure window by the cover member provided on the cartridge 4A is operated when the back cover is locked. When locked in the closed position, it is arranged so as to be substantially parallel to the upper surface of the main body upper wall 5A from the viewpoint of operability.

けられなかった。However, when the camera IA is configured as described above, the height of the cartridge is Ll, and the thickness of the upper wall and lower wall of the main body is III+I'4%, as shown in Fig. 7. If the height of the opening/closing operation section protruding from the upper surface of the upper wall of the main body is L8, then the opening for locking the back cover with a height of L is between the upper edge of the screw 4A and the upper wall of the main body 5A. Since the distance between the upper edge and the inner surface of the upper wall of the main body must be set larger than the distance between the upper edge and the inner surface of the main body, the overall height of the camera
It was inevitable that Ll would be slightly larger than the sum of Ll and up.

のである。The invention aims to solve the problem by making the dimension between the top and bottom walls of the camera body smaller than the dimension of the cartridge in the same direction, without completely storing the entire cartridge inside the camera body, as in conventional disk cameras. However, the objective is to obtain a device that can reduce the appearance of the camera and the overall height of the camera.

と当接したロック位置で回転を停止される。The cover drive member 2 is connected to the gear portion 18e of the back cover opening/closing member 18 via the intermediate gear 22 in conjunction with this rotation.
3 is rotated counterclockwise, and simultaneously moves the cover member (not shown) that opened the exposure window 13a of the cartridge 13.
The exposure window 13a is moved to a position where it is shielded from light. At the same time, the tip bent claw portion 25a of the back cover opening/closing member 18 is inserted into the retaining groove 15 formed on the lower surface of the engagement protrusion 15 of the back cover protrusion 12.
The locking claw 26 is moved in the direction of releasing the locking with a.
a is connected to the free end 27 by the engagement protrusion 15 of the back cover protrusion 12.
a passes behind the bent branch portion 2'7b of the plate spring member 27 pressed into the recess 20a of the shielding protrusion 20 (see FIG. 5), and then the tip bent claw portion 25a passes through the engagement groove 15a.
The bond with the person is released. At this time, the exposure window 13 has already been shielded from light by the cover member Zo. Therefore, the back cover 3, which has been released from the back cover opening/closing member 18, engages the engagement protrusion 15 with the free end 27a of the leaf spring member 27. The cartridge storage chamber 14 is automatically opened by pressing the front wall 15c of the cartridge storage chamber 14. When the back cover 3 is opened, the plate spring member 27, which is released from the pressure by the engagement protrusion 15, is moved toward the back cover 3 by elastic action, so that the bent branch 27b
This is because the locking claw 26a enters the rotational trajectory of the locking claw 26a and locks the locking claw 26a of the back cover opening/closing member 18, which is biased clockwise by the spring 21, against the biasing force of the spring 21.
(See FIG. 5), the back cover opening/closing member 18 is held in the open position. Therefore, the cartridge 13 loaded in the cartridge storage chamber 14 can be removed from the open part of the back cover 3 and the IJ screw 13 can be attached to the new car. When the back cover 3, which is pivotally attached to the lower wall 2b of the camera body 2, is pressed in the direction of closing around the pivot portion, the engagement protrusion 15 of the back cover protrusion 12 engages the body protrusion 11. Since the free end 27& of the leaf spring member 27 is inserted into the notch 16 and pushed into the recess 20& of the shielding protrusion 20 by the front wall 15o against its biasing force, the bent branch 27b is formed as shown in FIG. The locking pawl 26a is moved from the rotation locus indicated by the solid line to outside the rotation locus illustrated by the dashed-dotted line. As a result of this retraction, the back cover opening/closing member 18, which had been held in the open position against the biasing force of the spring 21, is released, and is rotated clockwise by the biasing force of the spring 21, so that the tip bending claw portion 25a into the engagement groove 15a of the back cover 3, and with the back cover 3 locked in the closed position, the protrusion 18d formed on the lower surface of the operating section 18b engages the upper wall 2a of the camera body 2.
Rotation is stopped at the lock position where it comes into contact with.
