Abstract
In a roll film carrier for rewinding the roll film wound on a supply reel onto a take-up reel there are provided a signal generating means which detects the rotation of the supply reel shaft and outputs a corresponding signal, a means for generating a pulse synchronously with the passage of the roll film and a means for controlling the driving of the roll film through comparison of the number of pulses generated in the signal generating period of the signal generating means with a predetermined number and it is so arranged that the driving of the roll film is stopped when the number of generated pulses has agreed with the predetermined number.
