MAGAZINE FOR PHOTOGRAPHIC PAPER AND PHOTOGRAPHIC PRINTING PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress an increase in the load on a drive mechanism and the tension on photographic paper even if a drawing out operation is going to be started during rewinding of the photographic paper. SOLUTION: This magazine has a winding central port 4a of rolled paper 4' wound in a roll form, an winding roll 18 rotated by the friction with the inside wall surface of the winding central port 4a and first and second spring members 21 and 22 which store the rotation of the winding core roll 18 during delivering of the photographic paper 4 as elastic force so as to act as the energizing force (back tension) in the winding direction. The elastic force of these spring members 21 and 22 are so set as to be weak in the initial period of rotation and to be stronger in the end period of rotation.
