Abstract
A light-shielded photosensitive material roll is provided in which a length of a light-shielding flanged cylinder is a length of an extent which enables easy insertion, industrially, of the flanged cylinder into a winding core of the photosensitive material roll, and also, the photosensitive material roll can be stably supported at any of various types of driving shafts. In the light-shielded photosensitive material roll, a spacer sheet, which has substantially a same thickness as a thickness of the light-shielding flanged cylinder, is bonded and fixed to an inner side wall surface of the winding core corresponding to a position at which a distal end portion of a cylindrical portion of the flanged cylinder is extended.
