    • 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.
    • 具有连接到盖的输送辊对的一个辊的打印机使得将输送辊对压在一起的机构和当使用少量零件打开盖时所使用的阻尼机构紧凑且低成本。 减震器弹簧27防止打印机1的盖单元3突然且强力地打开。 具有设置在其远端的第一从动辊33b的辊支撑杆38可旋转地并可移动地附接到盖单元3.辊支撑杆38被阻尼弹簧27推动,并且第一从动辊33b在远端 其端部被按压到打印机框架11侧上的第一输送辊33a。 当盖单元3打开时,减震弹簧27用作阻尼机构,并且当盖单元3关闭时用作第一输送辊对33的压力机构。
