Claims

[Claims for Utility Model Registration] (1) A rotating platen roller with printing paper attached to its outer periphery, a lever whose rotation center is at a position different from the rotation center of the platen roller on the end face of the platen roller, and the platen. A clamp mechanism comprising a clamper that extends horizontally between the levers parallel to the longitudinal direction of the rollers and presses the printing paper against the outer periphery of the platen roller by rotational displacement of the levers. (2) The scope of the utility model registration claim is that the lever is configured to be engaged with and driven by a drive member provided outside the platen roller when the platen roller is in a position where the printing paper is fed. The clamp mechanism according to item 1. (3) The lever is configured to be driven by the driving member to displace the clamper and separate it from the platen roller to a position that does not interfere with paper detection by the paper detection means when the printing paper is at a position where the printing paper is fed. A clamping mechanism according to claims 1 and 2 of the utility model registration claims.
