PURPOSE:To prevent the damage of a shutter and to realize a high performance shutter by executing an opening control characteristic of the cover for fitting the film, opening a shutter, and closing the shutter in accordance with the closing control characteristic of the cover before the film is wound up. CONSTITUTION:When a rear cover is closed, a switch SW (in a rear cover opening closing detecting device 3) is turned on by interlocking t the cover, and the rear cover opening signal is inputted through a resistance R1 to a CPU6, and therefore, the energizing to a solenoid 22 is stopped, a charging force for the pre-action is released and the shutter is opened. Thus, the shutter can not be damaged. When the rear cover is closed after the film fitting, etc., are executed, interlocking to it, the switch SW is turned off by interlocking to them and therefore, the CPU6 outputs a shutter closing signal to a solenoid 23 for a post-action trigger.
