Claims

[Claims for Utility Model Registration] (1) A device for attaching a tape take-up reel hub to a reel-to-reel type tape running device, comprising: a base member coupled to a reel flange of the tape running device; a pressing member that is movably assembled and has a pressing protrusion on its outer periphery that can come into contact with the outer surface of the reel hub through a guide groove on the inner periphery of the reel hub; an elastic member that presses and biases; a ring-shaped elastic body that is interposed between the base member and the pressing member and whose diameter can be expanded and brought into contact with the inner periphery of the reel hub by rotating the pressing member; In the tape take-up reel hub fixing device, an arc-shaped sliding member that can come into contact with the inner periphery of the ring-shaped elastic body and is divided into a plurality of parts in the circumferential direction is disposed, and a sliding member is arranged between the sliding member and the base member. A sliding guide portion is formed to allow the sliding member to move in the radial direction, and the sliding member is moved in the radial direction by rotation of the pressing member between the sliding member and the pressing member. A tape take-up reel hub fixing device, characterized in that a cam portion is formed that allows a ring-shaped elastic body to expand in diameter. (2) A cam portion is formed between the base member and the pressing member to maintain concentricity with the base member and guide the pressing member in the axial direction and the circumferential direction. Tape take-up reel hub fixing device.
