PROBLEM TO BE SOLVED: To provide a good printing quality by enhancing a printing precision of a rear end of a printing device (movement of a recording paper feed roller by a recording paper rear end). SOLUTION: A rotation load variable method to the recording paper feed roller is carried out by a power transmission path to the recording paper feed roller. The rotation load variable method to the recording paper feed roller varies a load to the periphery of the recording paper feed roller. A means is set for changing an application method of the load to the recording paper feed roller by recording papers. The application method of the load to the recording paper feed roller by recording papers is made variable by a thickness of the recording papers. COPYRIGHT: (C)2004,JPO
