Abstract

A printer includes a transport unit, a recording unit, a cutter unit, and a control unit. The transport unit is capable of transporting two pieces of roll paper in parallel. The cutter unit is movable in a width direction intersecting a transport direction, and is capable of cutting the two pieces of roll paper. The cutter unit is capable of cutting roll paper PR in both a forward path and a return path of the movement in a width direction. The control unit is capable of setting a standby position of the cutter unit to a position between the two pieces of roll paper.

First claim

What is claimed is:

1. A recording device, comprising:
a transport unit configured to transport two long media in parallel;
a recording unit configured to perform recording on the two long media transported in parallel;
a cutting unit disposed downstream the recording unit in a transport direction of the long medium, configured to move in a width direction intersecting the transport direction, and configured to cut the two long media; and
a control unit configured to control the transport unit, the recording unit, and the cutting unit, wherein
the cutting unit is configured to cut the long medium in both a forward path and a return path of the movement in the width direction,
the control unit is configured to set a standby position of the cutting unit to a position between the two long media, and
the cutting unit includes:
a main body portion provided movably in the width direction,
a first cutting blade provided on one side with respect to a center in the width direction of the main body portion and configured to cut the long medium in the width direction, and
a second cutting blade provided on another side with respect to the center in the width direction of the main body portion and configured to cut the long medium in the width direction.

2. The recording device according to claim 1 , wherein
the control unit is configured to set a standby position in the width direction of the cutting unit to a first position on an outside in the width direction with respect to the long medium, and to a second position between the two long media.

3. The recording device according to claim 2 , wherein
the control unit is configured to change the second position in the width direction, in accordance with a size in the width direction of the long medium being transported.

4. The recording device according to claim 1 , wherein
the control unit returns the cutting unit to a position between the two long media after the cutting unit cuts any one of the two long media.

5. The recording device according to claim 1 , wherein
the control unit does not return the cutting unit to a position between the two long media when, after one of the two long media is cut, and subsequently the one of the long media is cut.

6. The recording device according to claim 1 , wherein the cutting unit further includes
a guide unit provided between the first cutting blade and the second cutting blade in the main body portion, and configured to guide the long medium cut by one of the first cutting blade and the second cutting blade in a direction away from another of the first cutting blade and the second cutting blade.

7. The recording device according to claim 1 , comprising:
a transmission unit configured to transmit position information in the width direction of the cutting unit to the control unit, wherein
the control unit, based on the position information, when at least a part of the cutting unit is positioned inside a transport region of the long medium, stops transport of the long medium by the transport unit.

8. A control method for a recording device including
a transport unit configured to transport two long media in parallel,
a recording unit configured to perform recording on the two long media transported in parallel, and
a cutting unit disposed downstream the recording unit in a transport direction of the long medium, configured to move in a width direction intersecting the transport direction, and configured to cut the two long media,
the cutting unit being configured to cut the long medium in both a forward path and a return path of the movement in the width direction,
the cutting unit including:
a main body portion provided movably in the width direction,
a first cutting blade provided on one side with respect to a center in the width direction of the main body portion and configured to cut the long medium in the width direction, and
a second cutting blade provided on another side with respect to the center in the width direction of the main body portion and configured to cut the long medium in the width direction, the control method comprising:
setting a standby position of the cutting unit to a position between the two long media; and
causing the cutting unit to cut the two long media on which recording was performed.
