ABSTRACT:
In a printer capable of performing recording on a recording medium such as an optical disk, a tray on which the recording medium is set is sent upstream or downstream by being nipped by a driving transfer roller rotatably driven by a motor and a driven transfer roller driven and rotated contacting it. When the tray is in a stillness state in a set position where the recording medium can be set, the assist control means generates rotation torque T1. When an external force F comes in effect on the tray, rotation torque T2is generated by friction between the driving transfer roller and the tray, but the rotation torque T1 becomes an assist force, and the driving transfer roller rotates while any slip between the tray and the driving transfer roller does not occur.
