Abstract

A recording apparatus includes a carriage which is capable of moving along a first direction, a first sliding section that is provided in the carriage, on one side in a second direction, which intersects the first direction, a second sliding section that is provided, in an arm section, which extends from the other side, protruding in the second direction, a tube that supplies the liquid, which is delivered from a liquid accommodation section, to the carriage, extends in a direction that intersects the second direction by extending out from the carriage, and extends in an opposite direction by turning back in a vertical direction, in which the tube extends in the direction that intersects the second direction by passing at least one of above and below the arm section.

First claim

What is claimed is:

1 . A recording apparatus comprising:
a recording head that performs recording by discharging a liquid onto a target recording medium; a carriage, on which the recording head is provided, and which is capable of moving along a first direction; a first sliding section that is provided in the carriage, on one side in a second direction, which intersects the first direction; a second sliding section that is provided in the carriage, in an arm section, which extends from the other side in the second direction, protruding in the second direction; a first guide member that extends in the first direction and supports the carriage by coming into contact with the first sliding section, and guides movement of the carriage; a second guide member that extends in the first direction, is disposed at an interval from the first guide member in the second direction, supports the carriage by coming into contact with the second sliding section, and guides the movement of the carriage; a liquid accommodation section that accommodates the liquid; and a tube, which is a tube that supplies the liquid, which is delivered from the liquid accommodation section, to the carriage, extends in a direction that intersects the second direction by extending out from the carriage, and extends in an opposite direction by turning back in a vertical direction, wherein the tube extends in the direction that intersects the second direction by passing at least one of above and below the abovementioned arm section.

2 . The recording apparatus according to claim 1 ,
wherein the first sliding section retains the carriage in the second direction by the first guide member being inserted between the carriage and the first sliding section in the second direction, wherein the second sliding section is supported from below by the second guide member, and wherein the tube is disposed in a position at which a distance from the first sliding section in the second direction is longer than a distance from the second sliding section.

3 . The recording apparatus according to claim 2 ,
wherein the tube is connected to the carriage above the arm section as a result of curving and turning back passing below the arm section.

4 . The recording apparatus according to claim 1 ,
wherein the first sliding section is provided in a lower section of the carriage.

5 . The recording apparatus according to claim 1 ,
wherein a distance between the tube and the first sliding section in the second direction is shorter than the distance between the first sliding section and the second sliding section.

6 . The recording apparatus according to claim 1 , further comprising:
a regulation unit that is provided in the arm section, and regulates separation of the second sliding section from the second guide member.

7 . The recording apparatus according to claim 6 ,
wherein the second guide member further includes a support section that supports by coming into contact with the second sliding section, and a facing section that is provided above the support section, and faces the support section, and wherein the regulation unit is provided with a third sliding section that comes into contact with the facing section and is capable of sliding.

8 . The recording apparatus according to claim 7 ,
wherein the regulation unit further includes a biasing member that biases the third sliding section toward the facing section.

9 . The recording apparatus according to claim 6 ,
wherein the regulation unit further includes a magnetic member, and wherein the magnetic member draws the second guide member to a second sliding section side using a magnetic force.

10 . The recording apparatus according to claim 1 ,
wherein a plurality of the tubes are provided, wherein, in the tubes, turnback portions, which curve, follow the movement of the carriage in the first direction, wherein a tube diameter conversion member is provided in a position that is shifted from a movement region of the turnback portions in the first direction, and wherein a tube diameter from the liquid accommodation section to the tube diameter conversion member is greater than a tube diameter from the tube diameter conversion member to the carriage through the turnback portions.

11 . The recording apparatus according to claim 1 ,
wherein a plurality of the tubes are arranged along the second direction, and a diameter of a tube that is closest to the first sliding section in the second direction is greater than those of the other tubes.

12 . The recording apparatus according to claim 11 ,
wherein the liquid is ink, and wherein the tube with the widest diameter supplies black ink to the recording head.

13 . The recording apparatus according to claim 11 ,
wherein a plurality of the liquid accommodation sections are provided along the second direction, wherein, among the plurality of liquid accommodation sections that are provided, at least a part of a liquid accommodation section that is positioned closest to the second sliding section in the second direction, and at least a part of the tube with the widest tube diameter are in the same position in the second direction, and wherein the liquid accommodation section that is positioned closest to the second sliding section is connected to the tube with the widest tube diameter.

14 . The recording apparatus according to claim 1 , further comprising:
a tube guide member that extends along the first direction, and guides the tube, wherein the tube guide member is arranged below the arm section.

15 . The recording apparatus according to claim 14 , further comprising:
a retaining member that extends along the first direction, and retains an ejection roller, which ejects the target recording medium, wherein the tube guide member and the retaining member are separated.

16 . The recording apparatus according to claim 1 ,
wherein the arm section extends in a lower section of the carriage protruding in the second direction from a center of the carriage in the first direction, and a tip end thereof extends downward.
