Abstract: A printer includes a print head, a platen roller, a frame, a release lever, and a spring. The print head performs printing on recording paper. The platen roller conveys the recording paper held between the platen roller and the print head. The print head and the platen roller are placed on the frame. The frame includes a side plate in which a frame groove is formed. The release lever moves relative to the frame. The spring is provided between the frame and the print head to urge the print head toward the platen roller. The platen roller is placed on the frame while being held between the frame groove and the release lever. The release lever moves to unblock the frame groove.
