Abstract
PURPOSE: To eliminate the disadvantage that the release takes place when the film is not completely wound up, by generating feed signals in rsponse to the shift of film to control the counting operations so that the count may take place only when the feed of the film is normal.
CONSTITUTION: At the end of the film winding operation, high level signals are fed to a gate 67, and counters 21 and 22 are supplied with pulses and advance stepwise so that the indicated levels of elements 41 and 42 are renewed. When the release takes place before the termination of the idle feeding operation, an FF 13 is reset, but a one-shot circuit 92 is left untriggered so that the front plane of the shutter is left stationary. When the release takes place in case the film feed is not accomplished normally, an FF 66 feeds high level signals to gates 71 and 91. Thus, even if a switch S7 is turned on by the release, the output of the gate 91 is left at a low level to leave the circuit 92 untriggered so that no current is fed to a magnet Mg1 to leave the front plane stationary.
