PURPOSE:To increase both the operability and the portability of a camera, by providing a means to hold the detecting part of a detecting mechanism at a prescribed phase in case no film is loaded into the camera. CONSTITUTION:When a film is loaded into a camera, a projected part 38a of a sprocket cam 38 is set at a position as shown in the diagram and the driving force is transmitted from a driving source M to turn the cam 38 counterclockwise. The engagement is impossible between a pin 37 implanted to a lever 35 and a fall part 41a of a slide lever 41 as long as a projection 18b of a slide lever 18 presses an end 31a of a lever 31 although the part 38a and the lever 35 are in contact with each other. As a result, both the cam 38 and lever 18 move continuously. When the part 38a and the lever 35 are in contact with each other, the engagement is released between a clutch plate 5 and a clutch lever 44 since the projection 18b is detached from the part 31a. As a result, the feed of the film is stopped to obtain a steady state. |
