Abstract
PURPOSE:To prevent sustained running of a motor, and permit the operation of a camera by putting a spurious perforation signal to a counter when there are no films in a film feed circuit. CONSTITUTION:When there is a film in the photographing position of a camera, a switch SW2 opens, and the pulses from an oscillator OSC as a spurious perforation signal enter a counter CUT by passing through an AND circuit AND2 and an OR circuit OR2, and a motor M stops when the counter CUT goes 8, although an FF1 is set at the rise of the output of a shutter driving circuit 2. In this case, the oscillator OSC may be generated by the revolutions of a spool or may be run free. With such constitution, not only the sustained running of the motor is prevented, but also the operation of the camera such as film winding is accomplished.
