Title:
ROLL FILM CAMERA
Document Type and Number:
Japanese Patent JPH04152328
Kind Code:
A
Abstract:

PURPOSE: To surely stop a film at a prescribed position and to prevent overrunning by arranging plural film hole detecting means in the feeding direction of the film and controlling the feeding of the film with a signal sequentially generated from a detecting means.

CONSTITUTION: Before the film is fed, a detecting element 8A detects a detecting hole, and a detecting circuit 9A outputs a H-signal and sends it to a CPU 11. The CPU 11 drives a motor 13 with the H-signal via a driver 12, and deeds the film. Then, when the feeding is advanced, and the detecting element 8B detects the detecting hole, a detecting circuit 9B outputs the H-signal and the CPU 11 intermittently operates the motor 13, to reduce speed. Further, when the feeding is advanced, and the element 8A detects the detecting hole, the driver 12 is braked to stop the motor 13. Thus, the feeding of the film is controlled with the signal from the detecting element, so that the film is surely stopped at the prescribed position and the overrunning can be prevented.
