PURPOSE:To check the movement of moving members which move at the exposure in photographing by providing such photoelectric elements which receive the light reflected from a film outside the optical path entering the film plane past a photographing lens. CONSTITUTION:Such a photoelectric element 7 which receives the light reflected from the film plane is provided outside the optical path entering the film plane by passing a photographing lens 1. Otherwise, a photoelectric element which detects the movement of the moving members at the photographing through the photographing lens is provided. The outputs of these photoelectric elements B-D input to operational amplifier circuits F-H, which send the signals to a comparator by receiving the output of the photoelectric element A for setting exposure conditions, so that the signal whether the movement of the moving members was accomplished or not is displayed in the display part or the operation command signal is sent to a control circuit. Thereby, the movement of the moving members is checked. |
