Abstract
A cutter blade drive mechanism reliably returns a cutter blade from a forward position to a retracted position. A rotation transfer mechanism, which transfers rotation of a drive motorto a drive gear, has a cutter blade return gearthat meshes with the drive gear, a compound gear (controller)to which rotation from the drive motoris transferred, and a transfer gearthat meshes with the compound gearand the cutter blade return gear. While an intermittent teeth partof the compound gearand the transfer gearare meshed, the cutter blademoves to the forward positionA. When the intermittent teeth partand the transfer gearare not meshed and the compound gear-side protrusionof the compound gearis in contact with a cutter blade return protrusionof a cutter blade return gear, the cutter blade return gearrotates in unison with the compound gear, the drive gearturns in the opposite direction, and the cutter bladereturns to the retracted positionB.
