Mechanism for locking cartridge compartment cover of camera

摘要

A cover-locking mechanism for locking a cover with respect to a cartridge compartment so that the cover is prevented from being opened when a film cartridge is accommodated inside the cartridge compartment with a film thereof being outside the film cartridge. The cover-locking mechanism is operated by using a driving force to drive either a film-feeding mechanism or a light-intercepting door of the cartridge disposed at an entrance/exit of the film thereof. If the mechanism is of a type of being operated by the driving force of the film-feeding mechanism, it is constructed to be controlled by a driving force to drive the film-feeding mechanism so that the cover is prevented from being opened when the film is outside the cartridge. Meanwhile, if the mechanism is of a type of being operated by the driving force of the light-intercepting door, it is constructed so as to be synchronized with the operation of the light-intercepting door; namely, the light-intercepting door is opened and the compartment cover is prevented from being opened when the film is fed outside the film cartridge, while the light-intercepting door is closed and the compartment cover can be opened when the film is rewound inside the film cartridge.
