Abstract
A camera with a cartridge chamber for accepting a film cartridge with film and a cover for covering the cartridge chamber. The camera has a locking mechanism that locks the cover when the cover is in a closed state and a releasing device for releasing the cover from a closed state. The locking mechanism includes a pivotable member having on one end a locking portion engageable with the cover to lock the cover in the closed state and on the other end a contact portion. A biasing member urges the pivotal member in a locking direction so that the locking portion engages the cover. The releasing member includes a motor is used to open the cover. The motor drives a crank member that is connected to an unlocking member via a link member, which is operable to rotate the pivotal member in a direction opposite to the cover closing direction to open the cover.
