Claims

[Claims for Utility Model Registration] 1. A roll sheet holder configured to hold both ends of a roll sheet with a pair of holding frames, each holding frame having a plurality of grooves in its axial direction at both ends. An expansion collet that has claws formed by cutting and is inserted into the end of the core tube of the roll sheet to support the core tube, and an expansion collet that is attached to the outer end of the expansion collet and expands the expansion collet inside it. A flange equipped with an expansion protrusion that guides to the side, an operating shaft that passes through the center of the flange, and a collet expansion member that is attached to the inner end of the expansion collet and connects one end of the operating shaft. and a rotary operation handle fixed to the other end of the operating shaft. A holder for a roll sheet, characterized in that the collet is configured to be fixed within a core tube of the roll sheet. 2. The roll sheet holder according to claim 1, wherein the elastic restoring force of the outer end claw of the expansion collet is weaker than the elastic restoring force of the inner end claw.
