Cartridge loading chamber of camera

摘要

A camera loading chamber into which a film cartridge is loaded by dropping the cartridge into an opening of the camera against the urging force of an urging member. The film cartridge is held within the loading chamber by a trapdoor which is closed over the loaded cartridge and held in its closed position by a locking mechanism. Upon releasing the locking mechanism, the cartridge is urged toward the exterior of the camera and causes the trapdoor to open under the urging force of the urging member. A stopping member causes the trapdoor to stop at a position between its closed position and its fully open position so that the cartridge is prevented from jumping out of the cartridge loading chamber.
