Film feeding control device and method for camera

A photo film feeding control device for a camera, having a feeding motor by use of which photo film is fed, wherein said photo film has plural groups of perforations formed therein, and arranged along one edge thereof and regularly at a first distance one group from another, each of said perforation groups being associated with one frame, and including two of said perforations arranged at a second distance therebetween, said photo film feeding control device comprising:

• a pulse generator for generating a pulse in synchronism with feeding of said photo film;
• a sensor, disposed to confront with said photo film, for detecting said perforations in said photo film being fed;
• a pulse counter for counting said pulse from said pulse generator while said photo film is fed by said first or second distance, said pulse counter starting counting said pulse upon movement of a first one of said perforations past said sensor, and finishing counting said pulse upon detection of a second one of said perforations at said sensor;
• a comparator for comparing a counted number of said pulse counted by said pulse counter with a first reference value upon finish of counting said pulse, said comparator generating a first comparison signal if said counted number is equal to or more than said first reference value;
• and
• a controller for driving said feeding motor after an exposure is taken and for effecting a stopping control of said feeding motor being driven, wherein said stopping control decelerates said feeding motor if said first comparison signal occurs while said photo film is fed, and stops said feeding motor upon detection of a third one of said perforations at said sensor, and wherein if said pulse counter finishes counting said pulse without occurrence of said first comparison signal while said photo film is fed, said controller still drives said feeding motor without effecting said stopping control.
