Abstract
In connection with a printer, a platen roller is configured to rotate in a first direction and to transport a recording medium. A print head facing the platen roller includes a head body portion having a printing portion to perform printing on the recording medium when the platen roller transports such medium. A supporting mechanism supports the head body portion, presses the head body portion against the platen roller, and moves the head body portion by rotation of the platen roller. An urging unit urges the head body portion toward the platen roller. When the platen roller rotates in a second direction opposite to the first direction, the supporting mechanism moves the head body portion by the rotation of the platen roller, and a contact position of the head body portion with respect to the platen roller is shifted while maintaining the head body portion pressed against the platen roller.
