FILM TAKE-UP DEVICE

摘要

PURPOSE:To prevent a film from being taken up helically or tremblingly by making the external diameter of a reel larger at a part close to a pawl engaging perforations than at the top part. CONSTITUTION:The take-up reel 8 is larger in external diameter at the internal part 8a close to the pawl 9 than at the tip part by the thickness of a both- surface adhesive tape 10 by winding the both-surface adhesive tape 10 around the part close to the inside of the pawl 9 and adhering a rubber cylinder 11 to the wound part and unwound part as the tip entirely. The film wound around by engaging the pawl 9 with perforations tends to deviate to the larger diameter part of the take-up reel, but this is specified by the flank of the pawl 9, so the winding position of the film becomes stable and the flim is wound securely without helical winding nor trembling winding.
