Abstract

Provided is a recording device that includes a recording head that ejects a liquid, a discharge unit that discharges a recorded recording medium, a discharge tray that receives a discharged recording medium, a first blowing unit that is disposed above the discharge unit and blows air toward one surface of the recording medium to be discharged to the discharge tray, and a second blowing unit that is disposed between the discharge unit and the discharge tray and blows air toward the other surface of the recording medium to be discharged to the discharge tray, and a control unit that controls the first blowing unit and the second blowing unit, in which deformation of the recording medium to be discharged is suppressed by the wind of the first blowing unit and the second blowing unit and the recording medium is discharged.

First claim

What is claimed is:

1. A recording device comprising:
a recording head that records by ejecting a liquid onto a recording medium;
a discharge unit that discharges the recording medium recorded by the recording head;
a discharge tray that receives, from a lower side in a vertical direction, the recording medium discharged from the discharge unit in a discharge direction;
a first blowing unit that is disposed above the discharge unit in the vertical direction and blows air, from upstream toward downstream in the discharge direction, to one surface of the recording medium to be discharged to the discharge tray;
a second blowing unit that is disposed between the discharge unit and the discharge tray in the vertical direction, the second blowing unit having a discharge unit side that is a side closest to the discharge unit and a discharge tray side that is a side closest to the discharge tray, the second blowing unit blowing air toward the discharge unit side in an upward direction, from upstream toward downstream in the discharge direction, to the other surface of the recording medium to be discharged to the discharge tray; and
a control unit that controls the first blowing unit and the second blowing unit, wherein
deformation of the recording medium to be discharged is suppressed by wind of the first blowing unit and the second blowing unit and the recording medium is discharged, and
wherein the air blowing directions of the first blowing unit and the second blowing unit are changeable, and the control unit causes the first blowing unit and the second blowing unit to blow air to the recording medium in a state of being discharged to the discharge tray, toward a downstream end portion in the discharge direction and side end portion in the width direction that intersects with the discharge direction.

2. The recording device according to claim 1 , further comprising:
a third blowing unit that is disposed between the discharge unit and the discharge tray in the vertical direction and blows air to the recording medium in a state of being discharged to the discharge tray, toward an upstream end portion.

3. The recording device according to claim 2 , wherein
the control unit causes the third blowing unit to blow air toward the side end portion in the width direction that intersects with the discharge direction in the recording medium.

4. The recording device according to claim 2 , wherein
the control unit causes the first blowing unit and the third blowing unit to continue to blow air continuously during a period when the recording medium is discharged from the discharge unit.

5. The recording device according to claim 4 , wherein
the control unit causes the first blowing unit and the third blowing unit to stop blowing air based on removal of the recording medium from the discharge tray or a lapse of predetermined time after the recording medium is last discharged from the discharge unit when the recording medium is continuously discharged from the discharge unit.

6. The recording device according to claim 1 , further comprising:
a fourth blowing unit that is disposed above the discharge unit in the vertical direction and blows air to the recording medium in a state of being discharged to the discharge tray, toward an upstream end portion.

7. The recording device according to claim 6 , wherein
the fourth blowing unit is disposed outside the first blowing unit in the width direction that intersects with the discharge direction, and the control unit causes the fourth blowing unit to blow air toward the side end portion in the width direction in the recording medium.

8. The recording device according to claim 6 , wherein
the control unit causes the fourth blowing unit to start to blow air as the upstream end portion in the recording medium is discharged from the discharge unit.

9. The recording device according to claim 8 , wherein
when the recording medium is continuously discharged from the discharge unit, the control unit causes the fourth blowing unit to stop blowing air after a preceding recording medium is discharged from the discharge unit until the downstream end portion of a succeeding recording medium to be discharged from the discharge unit succeeding the preceding recording medium starts to be discharged from the discharge unit.

10. The recording device according to claim 8 , wherein
the control unit causes the fourth blowing unit to stop blowing air based on removal of the recording medium from the discharge tray or lapse of predetermined time after the recording medium is last discharged from the discharge unit when the recording medium is continuously discharged from the discharge unit.

11. The recording device according to claim 6 , wherein
the control unit causes the first blowing unit and the fourth blowing unit to change air blowing directions in accordance with a position of the side end portion in the width direction that intersects with the discharge direction in the recording medium in the state of being discharged from the discharge tray.

12. The recording device according to claim 1 , wherein
the control unit causes the second blowing unit to blow air after the downstream end portion in the recording medium starts to be discharged from the discharge unit until an upstream end portion in the recording medium is discharged from the discharge unit and causes the second blowing unit to stop blowing air as the upstream end portion in the recording medium is discharged from the discharge unit.

13. The recording device according to claim 1 , wherein
the first blowing unit and the second blowing unit are disposed above an upper limit of stacking height of the recording medium to be stacked on the discharge tray in the vertical direction.

14. The recording device according to claim 1 , wherein
the control unit causes the first blowing unit and the second blowing unit to change air blowing directions in accordance with a length, in the discharge direction, of the recording medium to be discharged from the discharge tray.

15. The recording device according to claim 14 , wherein
the control unit causes the first blowing unit and the second blowing unit to change air blowing directions following a position of the downstream end portion in the recording medium to be discharged from the discharge tray.

16. A recording device comprising:
a recording head that records by ejecting a liquid onto a recording medium;
a discharge unit that discharges the recording medium recorded by the recording head;
a discharge tray that receives, from a lower side in a vertical direction, the recording medium discharged from the discharge unit in a discharge direction;
a first blowing unit that is disposed above the discharge unit in the vertical direction and blows air, from upstream toward downstream in the discharge direction, to one surface of the recording medium to be discharged to the discharge tray;
a second blowing unit that is disposed between the discharge unit and the discharge tray in the vertical direction and blows air to the discharge unit side of the vertical direction, from upstream toward downstream in the discharge direction, to the other surface of the recording medium to be discharged to the discharge tray;
a third blowing unit that is disposed between the discharge unit and the discharge tray in the vertical direction and blows air to the recording medium in a state of being discharged to the discharge tray, toward an upstream end portion; and
a control unit that controls the first blowing unit and the second blowing unit, wherein
deformation of the reco
