Title:
FILM FEED CONTROLLER FOR CAMERA
Document Type and Number:
Japanese Patent JP2948036
Kind Code:
B2
Abstract:
PURPOSE: To shorten the winding time and the rewinding time of a final frame by stopping the winding of film at the 1st perforation only in the case of the final frame when the final frame of the film can be recognized.
CONSTITUTION: A photoreflector 7 inputs two perforation signals per frame. A control circuit 50 prepares for stopping by performing DUTY control to a motor driving circuit 58 after detecting the 1st perforation signal, and stops the driving of a motor by detecting the 2nd perforation signal. Furthermore, the photoreflector 7 inputs the perforation signal, and the control circuit 50 prepares for the stopping by performing the DUTY control to the circuit 58 after detecting the 1st perforation signal. However, in the case of the final frame, the second perforation signal is not detected, so that the driving of the motor is stopped after the elapse of a fixed time.
