Camera including jam detection and correction mechanism for automatic film feed cartridge system

摘要

A camera for thrusting a film from a film cartridge by rotationally driving a spool in the film cartridge has a measuring construction for measuring the amount of the film thrust from the film cartridge, a sensing construction for sensing the position of a leader of the film thrust from the film cartridge, and a determining circuit for determining whether the film is moving properly, based on the measured thrust amount of the film and the sensed position of the leader of the film.
