<p>PROBLEM TO BE SOLVED: To provide a label printer wherein a ground paper is wound up, while the paper is being pulled under certain tension, and the forward end of the paper can be easily attached to a bobbin. SOLUTION: The label printer includes a shaft member 303 rotabably supported by a vertical wall 11a, a cylindrical bobbin body 304 which rotates together with the member 303, a lever member 305 which is disposed between the bobbin body 304 and the shaft member 303 so as to be slidably supported by the member 303 in the axial direction, a spring 308 which urges the lever member 305 to the wall 11a, guide grooves 305c, 305c which upwardly guide the lever member 30 when it is moved toward the wall 11a to hold a mounting paper between the member 305 and the bobbin body 304, and a second protrusion 305e which fixes the member 305 to a predetermined location where the member 305 is pulled out to the side in opposition to the wall 11a against the urging force of the spring 308.</p> |
