    摘要: In a drop-in loaded camera, a back lid is opened to its predetermined open position by magnetic repulsion produced by magnetic members disposed on the back lid and the camera body when releasing a back lid latch that keeps the back lid closed. The back lid thus opened is held in that open position by magnetic attraction, in which a film supply chamber is exposed at the bottom of the camera for the insertion of a patrone with a leader previously withdrawn therefrom. In that open position there is also provided a slot for the threading of the leader in an exposure position. The back lid is free to move farther open, beyond that predetermined open position, but against that magnetic attraction. In this way, the lid when released automatically seeks that partially open positon for film loading and unloading, but is more fully openable merely by pulling it farther open against the same magnetic force that tends to maintain it in the partially open position. Thus the camera can be fully opened for inspection, repair, etc. without the need to provide any additional structure.
