Abstract
Abstract A magazine for belt-shaped photosensitive material in which the photosensitive material is in the form of a roll and is rotatably supported by a casing of the magazine. The photosensitive material is pulled through a slot formed in the casing and a small tab piece is attached to at least one of two lateral edges of the photosensitive material so that the small piece protrudes in the widthwise direction of the photosensitive material. The sum of the length of the protruding small piece and the width of the photosensitive material is larger than the length of the slot. A leading end protector is detachably mounted to the casing. The protector extends along the widthwise direction along the front end portion of the photosensitive material and prevents the front end portion from being bent or deformed.
