Abstract
A cutter blade drive mechanism reliably returns a cutter blade from a forward position to a retracted position. A rotation transfer mechanism 34, which transfers rotation of a drive motor 31 to a drive gear 32, has a cutter blade return gear 50 that meshes with the drive gear 32, a compound gear 40 to which rotation from the drive motor 31 is transferred, and a transfer gear 51 that meshes with the compound gear 40 and the cutter blade return gear 50. While an intermittent teeth part 43a of the compound gear 40 and the transfer gear 51 are meshed, the cutter blade 21 moves to the forward position 21A. When the intermittent teeth part 43a and the transfer gear 51 are not meshed and the compound gear-side protrusion 44b of the compound gear 40 is in contact with a cutter blade return protrusion 50b of a cutter blade return gear 50, the cutter blade return gear 50 rotates in unison with the compound gear 40, the drive gear 32 turns in the opposite direction, and the cutter blade 21 returns to the retracted position 21B.
