When the back cover 3 is opened from the state in which the back cover 3 is stored and the back cover 3 is closed, an operating finger is hooked on the tip inclined surface 18c of the operation unit 18b of the back cover opening / closing member 18 to move the operation unit 18b. When is pulled up, the back lid opening / closing member 18 is rotated counterclockwise around the pivot portion of the substrate 17 against the biasing force of the spring 21. Interlocking with this rotation, the cover drive member 23 connected to the gear portion 18e of the back lid opening / closing member 18 via the intermediate gear 22 is rotated counterclockwise, and the cartridge 13 is rotated.
The cover member (not shown) that has opened the exposure window 13a is moved together and moved to a position where the exposure window 13a is shielded from light. At the same time, the tip bending claw portion 25a of the back lid opening / closing member 18
Is moved in a direction to release the engagement with the engagement groove 15a formed on the lower surface of the engagement protrusion 15 of the back lid protrusion 12, and the locking claw 26a is engaged with the engagement protrusion 15 of the back lid protrusion 12. The free end 27a passes behind the bent branch portion 27b of the leaf spring member 27, which is pressed by the concave portion 20a of the shielding projection 20 by the portion 15 (see FIG. 5), and then the tip bending claw portion 25a The engagement with the engagement groove 15a is released. At this time, the exposure window 13
Is already shielded from light by the cover member.

Open up. When the back cover 3 is opened, the engaging protrusion 1
The leaf spring member 27 released from the pressing force of 5 is moved to the back cover 3 side by the elastic action, so that the bent branch portion 27b is formed.
Enters the turning locus of the locking claw 26a and locks the locking claw 26a of the back lid opening / closing member 18 biased clockwise by the spring 21 against the biasing force of the spring 21 ( (See FIG. 5), the back lid opening / closing member 18 is held in the open position. Therefore, the cartridge ledge 13 loaded in the cartridge storage chamber 14 can be taken out from the open portion of the case back 3 and a new cartridge ledge 13 can be attached.

Since the portion 15 is fitted into the notch 16 of the main body protrusion 11 and pushes the free end 27a of the leaf spring member 27 into the recess 20a of the shielding protrusion 20 against the biasing force of the front wall 15c, the portion 15 is folded. The bent branch portion 27b is retracted from the rotation locus of the locking claw 26a shown by the solid line in FIG. 5 to the outside of the rotation locus shown by the alternate long and short dash line. Due to this retreat, the back lid opening / closing member 18 held in the open position against the biasing force of the spring 21 is released from the lock, and the tip bending is rotated clockwise by the biasing force of the spring 21. The projection 18d formed on the lower surface of the operation portion 18b is inserted into the engaging groove 15a of the back cover 3 and the back cover 3 is locked at the closed position.
The rotation is stopped at the lock position where it abuts.

とがないから、カメラの小型化を妨げることはない。Therefore, the dimension l 1 between the upper and lower walls of the camera is set to the cartridge edge 13.
Even if it is smaller than the dimension l 2 in the same direction of the camera body 2,
The cartridge 1 is placed in a cartridge storage chamber 14 formed by the main body projection 11, the back cover 3 and the back cover projection 12.
3 can be loaded, so that not only the appearance of the camera but also the height H of the entire camera can be reduced to miniaturize the camera for the disc-shaped film cartridge. In this case, the tip bending claw portion 25a of the back lid opening / closing member 18 that opens and closes the back lid 3 is disengaged from the engagement groove 15a formed in the lower surface of the engagement protrusion 15 of the back lid protrusion 12. Since it does not project above the main body projecting portion 11 and the back cover projecting portion 12, the miniaturization of the camera is not hindered.
