Abstract
An apparatus that can be loaded with a film cartridge provided with a light-blocking door for opening and closing a film intake/outlet slot, comprises an opening/closing mechanism that opens and closes the light-blocking door, a cartridge chamber where the film cartridge is housed, a cartridge chamber lid that opens and closes a cartridge insertion access of the cartridge chamber, an operating device that is capable of moving between a non-allowing position at which opening of the cartridge chamber lid is prevented and an allowing position at which opening of the cartridge chamber lid is allowed, and a locking mechanism that becomes displaced to a state in which the operating device is prevented from moving to the allowing position and to a state in which the operating device is free to move to the allowing position, with an operation of the opening/closing mechanism.
