Abstract
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 springprevents the cover unitof the printerfrom opening suddenly and forcefully. A roller support leverhaving the first follower rollerdisposed to the distal end thereof is attached rotatably and movably to the cover unit. The roller support leveris urged by the damper spring, and the first follower rolleron the distal end thereof is pressed to the first transportation rolleron the printer frameside. The damper springfunctions as the damping mechanism when the cover unitopens, and as the pressure mechanism of the first transportation roller pairwhen the cover unitis closed.
