Abstract

A photographic camera is provided with a cartridge chamber in which a film cartridge is loaded. A chamber lid is movable between an opening position in which it opens an entrance opening to the cartridge chamber and a closed position in which it closes the entrance opening. A lock lever is moved to a locking position in response to movement of the chamber lid to the closed position to lock the chamber lid in the closed position and is moved to an unlocking position to release the chamber lid in response to an operation for opening the chamber lid. The lock lever is urged toward the locking position by a spring. A lifter is disposed in a first position where it is brought into abutment against the film cartridge when the film cartridge is loaded in the cartridge chamber, is moved by the film cartridge in response to loading of the film cartridge in the cartridge chamber to a second position where it can be brought into abutment against the chamber lid when the chamber lid is moved to the closed position, and is moved, by the chamber lid in response to movement of the chamber lid to the closed position, to a third position where it is away from the film cartridge. the lifter is urged toward the first position by the spring which urges the lock lever.
