Abstract

An ink jet type printer includes a recording head that performs recording on a paper sheet by ejecting ink, a carriage that reciprocates in a width direction while supporting the recording head, and a power supply unit that supplies electricity to driving targets including a driving source of the carriage and the recording head. The power supply unit is disposed such that at least a part thereof overlaps with a moving region of the carriage on an upper side.

First claim

What is claimed is:

1. A recording apparatus comprising:
a recording head that performs recording on a recording medium by ejecting a liquid;
a carriage that reciprocates in one direction while supporting the recording head; and
a power supply unit that supplies electricity to driving targets including a driving source of the carriage and the recording head,
wherein the power supply unit is disposed such that at least a part thereof overlaps above in a vertical direction with a moving region of the carriage such that the moving direction is below the at least part of the power supply unit in the vertical direction.

2. The recording apparatus according to claim 1 , further comprising:
a liquid supply path through which the liquid is supplied from below the moving region to the recording head,
wherein the liquid supply path passes below the power supply unit and causes the liquid to be supplied to the recording head.

3. The recording apparatus according to claim 2 ,
wherein the liquid supply path curves downward and is connected to the carriage after passing below the power supply unit and passing a height position at an upper end of the power supply unit.

4. The recording apparatus according to claim 1 ,
wherein the power supply unit is disposed at a position where the power supply unit does not overlap with a standby position of the carriage in a vertical direction.

5. The recording apparatus according to claim 1 ,
wherein an image reading section that reads an image of a document is disposed above the power supply unit, and
wherein a heat insulation member is disposed between the power supply unit and the image reading section.

6. The recording apparatus according to claim 1 ,
wherein a heat dissipation section that dissipates heat generated in the power supply unit is disposed on a lower surface of the power supply unit.

7. The recording apparatus according to claim 1 ,
wherein a rib extending in a direction that intersects with the one direction is provided at an upper end portion of the carriage.

8. The recording apparatus according to claim 1 ,
wherein the power supply unit is disposed at a position where the power supply unit corresponds to an end portion of the moving region of the carriage in the one direction, and at least a lower surface and a side surface on a center portion side of the moving region of the carriage in the one direction are shielded.

9. The recording apparatus according to claim 8 ,
wherein the power supply unit has an opening for communicating with an outside on a surface other than the shielded surface.

10. The recording apparatus according to claim 9 ,
wherein the power supply unit has a fan that discharges inside air to the outside from the opening.

11. The recording apparatus according to claim 9 ,
wherein the power supply unit has a fan that sucks in outside air from the opening.

12. The recording apparatus according to claim 11 , further comprising:
a supply section that supplies the recording medium at a rear portion of the apparatus,
wherein the opening is disposed on the supply section side and the fan sucks in air from the supply section.

13. The recording apparatus according to claim 11 ,
wherein the power supply unit accommodates a power supply substrate mounted with a converter which is a heat generating component and a heat sink which is in contact with the converter, and
wherein the heat sink is disposed along a surface on which the fan is disposed in the power supply unit.
