A printer having one roller of a transportation roller pair attached to cover renders the mechanism pressing the transportation roller pair together and the damping mechanism used when opening the cover using few parts, compactly, and at low cost. A damper spring 27 prevents the cover unit 3 of the printer 1 from opening suddenly and forcefully. A roller support lever 38 having the first follower roller 33b disposed to the distal end thereof is attached rotatably and movably to the cover unit 3. The roller support lever 38 is urged by the damper spring 27, and the first follower roller 33b on the distal end thereof is pressed to the first transportation roller 33a on the printer frame 11 side. The damper spring 27 functions as the damping mechanism when the cover unit 3 opens, and as the pressure mechanism of the first transportation roller pair 33 when the cover unit 3 is closed. |
