The photographic film F set in this camera is rotated in a light room by a motor or the like, and the photographic film F of the patrone 2 is wound on the winding shaft 1 to complete the setting.

Use of Camera The film-integrated camera having such a configuration is compact, and in the film-integrated camera, the unexposed portion of the photographic film F is set at the position of the screen frame 11 from the beginning, so that the user needs It is possible to immediately obtain a photographable state without any prior operation.

Then, in the film-integrated camera in a photographable state, when the release button 26 is pressed, the operating member 72 activates the shutter mechanism 90 to take a picture, and the winding knob 51 is wound up in a counterclockwise direction, whereby the photographic film F is wound up. One screen feed, the sprocket 54 rotates and the film counter 60 rotates, the operating member 72 returns to the initial position, the shutter charge and the film counter operate, and the next frame can be photographed. In this case, the photographer does not need to wind the photographic film to perform the photographing operation, which is convenient.

Then, the release button 26 is at the rotation position of the last photographing frame, and does not return to the initial position even if the photographic film F is wound up. After the last photographing frame, the release button 26 cannot be operated and photographing is not performed.

The above is the action of the user, but if the user or the processor continues to take several shots thereafter, the entire photographic film F is wound up on the winding shaft of the patrone 2 and can be taken out.

In the light room, the processor can remove the cover 30 from the engagement with the main body 10 and easily separate it after being pryingly joined by a driver or the like. The photographic film F which is wound and shielded can be taken out and processed.

[Effect of the Invention] As described above, according to the first aspect of the present invention, the movement of a member interlocked with the winding of the photographic film due to the rotation of the winding shaft through the opening of the camera body is detected, and the number of windings is determined. By counting and controlling the winding amount of the winding shaft based on the number of windings, the winding amount of the photographic film can be easily and reliably controlled in a bright room from the outside of the camera body.

According to the second aspect of the invention, the number of windings is counted by detecting the movement of a member interlocked with the winding of the photographic film by the rotation of the winding shaft through the opening of the camera body, and the number of windings is calculated from the number of windings. By controlling the winding amount of the take-up shaft, the winding amount of the photographic film can be easily and reliably controlled in a bright room from the outside of the camera body.
