Abstract

PURPOSE: To simplify the constitution of a frame feeding device, by electronically controlling the motor depending on the shutter opening detection signal and closing of frame feeding switch.
CONSTITUTION: When the film is fed by a motor 2, and a detecting shutter 7 is turned by the motor 2 near the end of the frame, and the emission of light emitting device 9 is detected by a photoelectric transducer 10, a high level output from a waveform shaping circuit 11 is supplied to a switch 12 which is connected to a contact 12b, so that FF 13 is reset. By this reset output or FF 13, a transistor 15 in a motor cnotrol circuit 14 becomes OFF, and the motor 2 stops, so does the film. When the frame feeding switch 16 is closed after closing the shutter, the FF 13 is set, and the transistor 15 is made to conduct, so that the frame feeding of the film is started by the motor 2. Therefore, driving and stopping of the motor are electronically controlled, so that the constitution of the frame feeding device may be simplified.
