PURPOSE:To release the lock state of a rear cover, even if an emergency state such as the damage of a film, etc., is generated, by constituting the titled device so that a lock control member detains a rear cover lock member and sets a rear cover to a lock state, only in case of winding the film, and it can be moved to a non-engaged position to the rear cover lock member by a manual operation. CONSTITUTION:When an emergency state such as the damage of a film, etc., is generated in the course of winding the film, and it is desired to open a rear cover 31, it can be executed by depressing a pressure operating part 22b of a lock control member 22 by a manual operation, from the pressure hole 51 of a lock member cover 45. In this way, the lock control member 22 slides in the direction B, therefore, the detention of a detained projecting piece 22c by a tip key part 50 is released, and the rear cover lock member 35 can slide downward. Accordingly, when the rear cover member 35 is depressed by an operating member 43, the engagement of the key spatula parts 48 and 49 is released, and the lock of the rear cover 31 is released, therefore, the film can be taken out.
