Abstract:
PURPOSE: To provide a film feeding controller which can control so that the position of perforation and the position of a photographic image plane become a desirable relative position even when film is fed at high speed.
CONSTITUTION: The film 4 is fed by a motor(M) 16 driven by a motor driving circuit 15. The specified amount of movement from a feeding start position is detected by a moving amount detecting part 12, thereafter, the reference position of the perforation is detected by a perforation detecting part(photointerrupter) 11.
