Abstract
A cutter blade moving mechanism moves a cutter blade to a forward position by a low output drive motor without an urging member urging the cutter blade to the forward position where media is cut. The first cutter blade moving mechanism has a drive gear that moves the first cutter blade forward and back; a drive motor; and a compound gear to which rotation of the drive motor is transferred. The intermittent teeth part of the compound gear meshes with a transfer gear after turning the compound gear is started by drive power from the drive motor, completing a rotation transfer path. Because there is a delay between when driving the drive motor starts and when the path transferring rotation from the drive motor to the drive gear is completed, rotational kinetic energy is stored in the compound gear during this delay. The transfer gear can therefore be turned with greater drive power (rotational kinetic energy) when the compound gear and transfer gear mesh.
