ABSTRACT:
A camera has a cover member for opening and closing a film cartridge-retaining chamber, and a detecting member movable to effect automatic setting of the film sensitivity or automatic change-over of a filter. The film cartridge has a signal element on its side wall of a predetermined size which may be engaged by the detecting member when the film cartridge is charged into the camera for effecting the automatic setting of the film sensitivity or of the automatic change-over of a filter. After the detecting member has engaged the signal element, and thus tends to tilt the film cartridge, the detecting member is moved in a direction away from the signal element due to a closing operation of the cover member, or the detecting member is released from a force which urges the detecting member toward the signal element, thereby eliminating the influence of the force acting to tilt the film cartridge.
