Claims

[Claims for Utility Model Registration] (1) A cylindrical core on which a long photosensitive material is wound, a flange body is brought into close contact with both ends of the core, and a leader paper having a light-shielding property connected to the tip of the long photosensitive material is wrapped around the core. In the roll-shaped photosensitive material formed by rolling the above,
A roll-shaped photosensitive material characterized in that a wide leader paper is connected to the tip of the elongated photosensitive member so that both edges of the leader paper protrude in the width direction. (2) Utility model registration claim 1, wherein an annular projection is provided on the outer periphery of the outer surface of the flange body, and both edge portions of the leader paper are wound around the outer periphery of the annular projection.
The roll-shaped photosensitive material described in . (3) Practical use in which a concentric stepped portion bulging outward is provided on the outer periphery of the flange body, and a flexible member having light-shielding properties that is bitten by both edges of the leader paper is attached to the stepped portion. A roll-shaped photosensitive material according to claim 1 of the patent registration claim. (4) A spacer is attached to the center of the inner surface of the flange body, and a flexible member having a light-shielding property that is bitten by both edges of the leader paper is attached to the outer periphery of the spacer. A roll-shaped photosensitive material according to scope 1. (5) The roll-shaped photosensitive material according to any one of claims 1 to 4 of the utility model registration claim, wherein the leading end side of the leader paper has the same width as the photosensitive material.
