Abstract

PURPOSE:To develop only a remaining part by discarding an unexposed part other than a film part rewound into a cartridge, by providing a means of manually releasing a member which stops the motion of a rear cover opening and closing member. CONSTITUTION:A rear cover 60 is locked to a camera body until a cam plate 61 rotates according to the rotation of a cartridge 35 to rewind all of a photographic film around the cartridge 35 by the lock lever of a stopping member, the pin 65a of an opening and closing pawl 65, etc. When a changeover knob 64 is moved manually as shown by an arrow C at an optional point in time in photography, the lever 62 rotates and the cover 60 is unlocked by the pawl 65 released from being stopped by the lever 62. Thus, the cover 60 is opened and only the remaining part of the photographic film other than an unexposed part is developed.
