Abstract

PURPOSE:To prevent erroneous photographing work when an original is not correctly placed by controlling photographing operation by combining the detection signal of the time when the original is in a photographing region and the detection signal of the time when it is outside the region. CONSTITUTION:An original is placed within the indices 5 showing the photographable region of an original placing plate 1a, and is detected with the 1st detector 6 having a phototransistor 6a, but if it is outside the region, it is detected by the 2nd detectors 7-10. If with this constitution the original is within the indices 5, the 1st detector 6 is non-conducting and the 2nd detectors 7-10 are conducting. An AND gate 21 goes to the high level by the prescribed circuits and the gate 21 opens, thereby operating the shutter. When the original deviates to the position of the detector 7, the detector 7 goes to the low level to prevent the gate 21 from opening, thereby inhibiting the shutter operation. Thereby, the photographing of the time when the original is not correctly placed is prevented.
