ABSTRACT:
A film cartridge loading mechanism includes a cartridge chamber into which a film cartridge is loaded, an eject member capable of traveling between a housing position at which the loaded film cartridge is held inside the cartridge chamber, and a take-out position at which a portion of the film cartridge projects out of the cartridge chamber, that travels to the housing position as the film cartridge is loaded and travels to the take-out position by an eject operation, a pressure applying member which presses the film cartridge which has been completely loaded in the cartridge chamber, in the direction of the longitudinal axis, to regulate a movement of the film cartridge, and a toggling force applying mechanism that applies a force to the eject member. The toggling force applying mechanism changes a direction of force application thereto while the eject member moves, in such a manner that the eject member at the housing position is held at said housing position and the eject member at the take-out position is held at the take-out position.
