is rotated 1c11, and the film is sequentially rewound. Then, since the part of the second cam part 30c with a large lift +lj comes into contact with the bottle 33K, the lever 32rj,
Against the action of the tel 34, the holder 36 is rotated to the left by f, and its retaining portion 32c engages with the lock pawl 40.

Next, open the table 4 and take out the cartridge 27 -1
- However, for this purpose, it is sufficient to rotate the clip member 10, the engagement member 11, and the member 12 integrally. '1'', that is, pull the locking member 12 in the direction of the arrow (FIG. 3) against the action of the spring 11 to remove the engagement between the notch 12a and the protrusion 13a of the protrusion 13.

'f That is, at this time, the protrusion 3a and the protrusion 30a are in a positional relationship in which they do not come into contact with each other, and the interlocking plate 30 is moved to the right in FIG. This is because the lever 32 is rotated to the right due to the action of the lever 33 and the spring 34. Further, since the interlocking plate 30 moves to the right and the first cam portion 30b maintains the rewinding interlocking shaft 24 in the raised position, the retaining portion 2
4a is not engaged with the spool engaging portion 27a of the cartridge 27. Therefore, even if rotational force is applied to the knife 5 during photographing, the cartridge 27 will not be affected. The clip member 10 and the retainer 11-0 member 12 (t:j) serve as a holding portion (grip) of the camera body 1.

As described above, in the preferred embodiment of the present invention (91J), the back cover (12) 4 equipped with the self-top type waterproof seal 6 is set to 15K < L, and the grip part 4: A10 is held as a lever. (Usage) Also, opening the back cover 4 is easy. In other words, the free end of the clip part (10) is the input part, the shaft 11 is the fulcrum, and the protrusion 10a is the output part. Since it is relatively large, a large output can be obtained by applying only a small amount of force, and 93 and 4 can be easily turned.

In addition, in this embodiment, in addition to the 15 clips 4′ and 1°, there are also 15 clips that can be snapped onto the camera body 1.
1 part (412 was adopted, so grip Ru8-4 i
This ensures that the camera back 4 remains closed in relation to the camera body 1.

However, it is essential to provide 12 locking members on the clip member i o vL, and
Even in combination with normal protrusions and recesses, when the clip member 10 is locked to the camera body 1, the condition will definitely be fixed. It's good.

As described above, according to the present invention, when the back cover is closed, water intrusion into the camera body is effectively prevented by the sealing member of the self-sealing set 11, and the back cover is closed by the lever of the clip member. Since it is easily opened by the action, the effect of expediting the replacement of the film, etc. is achieved.
