An antenna for communication with the wireless tag is on an outer peripheral surface of the shaft. A wiring is on the outer peripheral surface of the shaft and connects to the antenna. A protective sleeve is provided to be between the shaft and the mounted ink ribbon roll. The protective sleeve covers an end portion of the shaft and the wiring at the end portion. A bearing is outside the protective sleeve. The bearing is rotatable about the protective sleeve. A printing unit is configured to perform printing on a medium to be printed with ink ribbon drawn out of the ink ribbon roll.
