ABSTRACT:
A camera using a film cartridge of the type that the spool shaft of the film cartridge is turned to initially feed the photographing film,in which, even if no film cartridge is loaded in it, the shutter can be charged and released, and it is unnecessary to charge and release the shutter during the initial film feeding operation. In the case where, in a camera, a film cartridge has been loaded with its rear cover closed, a clutch gear for driving a charge gear is spaced away from a winding gear, so that the shutter is held released. On the other hand, when no film cartridge has been loaded in the camera, the clutch gear for driving the charge gear is moved by a second engaging lever to engage with the winding gear, so that the shutter can be charged and released.
