Abstract

PURPOSE:To prevent a double exposure which is caused by a careless push of the shutter button, by providing a means to lock the shutter when the film is in the consecutively winding state. CONSTITUTION:When no cartrige is loaded, a cartridge detecting lever 37 is pulled by a spring 91 and turned clockwise. Thus a pin 37a is set free, and a changeover knob 39 is pulled by a spring 41. Under such conditions, a shutter button 99 can be pushed. When a cartridge is loaded, the lever 37 is pushed and turned counterclockwise. Thus the knob 39 is moved toward an arrow A by the pin 37a. Under such conditions, the projected part 39b of the knob 39 goes under the shutter button 99. Thus a shutter actuating lever cannot be pushed down to the working position although the button 99 is pushed. When the winding of film is over, the knob 39 is further moved toward the arrow A. Then the button 99 is put into push-down feasible state.
