DELIVERY CONTROL DEVICE AND METHOD FOR LONG SIZED PHOTOGRAPH FILM

摘要

PROBLEM TO BE SOLVED: To provide a device and method for manufacturing a photograph roll film capable of easily changing photograph roll films of two or more sizes in manufacture. SOLUTION: A controller calculates the winding diameter of a film roll 116A or 116B in accordance with the rotating speed of a driving motor 112 at the time when a long sized photograph film 110 is delivered at a preset length corresponding to a preset film size from the film roll 116A or 116B on which the long sized photograph film 110 is wound. It has a rotation control means 190 for dividing the rotating speed to deliver the long sized photograph film 110 at a preset length within a preset time in accordance with the winding diameter in order to set a corrected rotating speed De, and a motor control circuit 202 for feedback control so that the rotating speed Sa of the driving motor 112 becomes the corrected rotating speed De within a preset time while comparing the corrected rotating speed De from the rotation control means 190 with the current rotating speed Sa of the driving motor 112.
