ABSTRACT:
A photographic camera has a cartridge chamber in which is loaded a film cartridge having a roll film entirely rolled to its leading end around a spool in a cartridge body and a light-shielding shutter member for opening and shutting a film exit slit formed in the cartridge body, an entrance opening to the cartridge chamber, and a chamber lid which is mounted on the camera to be moved between an opening position where it opens the entrance opening and a closed position where it closes the entrance opening. A shutter lock member moves to a shutter locking position, where it prevents release of the shutter of the camera, in response to operation of a rewind button. A holding member holds the shutter lock member in the shutter locking position, and a release member causes the holding member to release the shutter lock member after closure of the light-shielding shutter member of the film cartridge in response to opening of the chamber lid.
