PURPOSE:To simplify the operation after taking out materials of double feed, where information should be recorded, and prevent malfunctions, by interlocking with the release mechanism of the driving stop to inhibit photographing and the operation of a number counter for a constant time. CONSTITUTION:When a double feed detector 9 is provided in such position that the detector 9 is turned off for one material 2, where information should be recorded, and is turned on for two or more materials 2 by the other end 11' of a holding arm, the double feed of materials 2 is detected. A releasing means F consists of a release detector 10 connected to a storage means E where the detection of the double feed is stored; and when the release detector 10 is operated, the releasing means F releases the operation of a double feed detector 9 through the storage means E. If the double feed is detected by the double feed detector 9, the driving of a photographing device, a driving device for microfilm, and a feeding device for materials where information should be recorded is inhibited. After that, when the release detector 10 is operated, the storage device E is released, and the inhibition of driving of the feeding device 1 is released. |
