Abstract
A cutting device which carries out cutting operations in a width direction of a tape-like member, includes: a cutter operation mechanism which causes the cutting operations, a full cutting and a half cutting, to be carried out with one mechanism; and a tape discharge mechanism having a tape discharge roller which, by rotating, causes the tape-like member to move to a discharge side, wherein the tape discharge mechanism comes in conjunction with the cutter operation mechanism, and the tape discharge roller rotates only after the cutting operation at a time of the full cutting finishes.
Claims3
A cutting device which carries out cutting operations in a width direction of a tape-like member, comprising:
- a cutter unit having a cutter blade;
- a cutter operation mechanism which causes the cutter unit to carry out both a full cutting operation and a half cutting operation, the cutter operation mechanism including
- a rotating circular plate which rotates by means of power input from a drive portion,
- a cam projection formed on the rotating circular plate, and
- a rotating gear formed on the rotating circular plate;
- and
- a tape discharge mechanism having a tape discharge roller which, by rotating, causes the tape-like member to move to a discharge side, wherein
- the tape discharge mechanism includes
- a transmission gear train which transmits power causing the tape discharge roller to rotate, and
- a clutch portion having a clutch gear portion, which transmits the power caused by the rotation of the transmission gear train, causing the tape discharge roller to rotate, and a fixed gear portion, which cuts off the power caused by the rotation of the transmission gear train, prohibiting the rotation of the tape discharge roller, and
- the tape discharge mechanism is such that the clutch portion and cam projection come into engagement, configuring a cam mechanism with the rotating circular plate, while the transmission gear train and rotating gear come into engagement, configuring a transmission mechanism with the rotating circular plate, and by means of the rotation of the rotating circular plate, the cam mechanism and transmission mechanism engage, causing the tape discharge roller to operate.
