Claims

[Claims for Utility Model Registration] 1. In a printing device equipped with a feed roller 8 that is rotated to feed printing paper to a printing position, a position where the feed roller 8 is engaged and a position where the feed roller 8 is disengaged. a presser roller 21 that is movably disposed on the frame 12 near the feed roller and rotates following the feed roller 8 when placed in the engagement position; an operating member 23 rotatably supported by the frame 12 to move between positions; and an operating member 23 supported by the frame 12 at one end and extending in a direction substantially perpendicular to the radial direction of the feed roller 8. It comes into contact with a part of the presser roller 21 at the end, and is connected to the operating member 23 at the intermediate portion, and as the operating member 23 rotates, the presser roller 21 is engaged with the feed roller 8. 1. A printing device comprising a leaf spring 25 that can be switched between a position where a pressing force is generated for printing and a position where the pressing force is released. 2. A utility model registration request characterized in that the presser roller 21 is movably disposed on the printing position side of the feed roller 8, and the other end of the leaf spring 25 extends substantially vertically. The printing device according to scope 1.
