US 2002/0171004 A1 · Photosensitive material roll

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.

Dependent claims

A photosensitive material roll which can be mounted in a predetermined machine via an adapter, comprising:

a hollow, cylindrical winding core;
an elongated photosensitive material sheet wound-up on the winding core;
an annular member installed in an opening of the winding core;
and
a spacer mounted to an inner peripheral wall of the opening of the winding core on an imaginary extension, along a direction of installing the annular member, of an installing side distal end portion of the annular member, so as to be positioned at a position which is separated by a predetermined distance from the distal end portion,
wherein the annular portion and the spacer can respectively work to integrally connect the winding core and the adapter.
