Abstract
PURPOSE:To prevent a rolled photosensitive material from being wasted by displaying the length from the final cut front end of the rolled photosensitive material to its rear end numerically on a display part. CONSTITUTION:The material length of the rolled photosensitive material R is measured and controlled by an encoder 8 and a main control part 16. The encoder 8 rotates associatively with a paper feeding motor M1 and, therefore, rotates in synchronism with a conveyor roller couple 10a, the pulse counted value of the encoder 8 indicates the circumferential length of the conveyor roller couple 10a, and the circumferential length indicates the material length of the rolled photosensitive material R. Here, the rear end of the rolled photosensitive material R is detected to display the actual material length which remains at the time of the detection, thereby enabling an original to be replaced corresponding to the actual material length. Consequently, the rolled photosensitive material R is prevented from being wasted.
