Abstract

A liquid ejecting apparatus includes a liquid ejecting head including a nozzle which ejects liquid, and an opening face to which the nozzle opens; a cap which forms a closed space between the cap and the opening face; and a holder which holds the cap so as to move in a tilting manner in a direction which goes along the opening face.

First claim

What is claimed is:

1. A liquid ejecting apparatus comprising:
a liquid ejecting head including a nozzle which ejects liquid, and an opening face to which the nozzle opens;
a cap which forms a closed space between the cap and the opening face, the cap including a plurality of engaging portions that are capable of engaging with a surface of the liquid ejecting head different from the opening face; and
a holder which holds the cap, the cap being rotatable around an axis that intersects a plane along the opening face until the liquid ejecting head engages with the plurality of engage portions.

2. The liquid ejecting apparatus according to claim 1 , further comprising:
a plurality of the liquid ejecting heads;
a plurality of the caps which are provided corresponding to the plurality of liquid ejecting heads, individually;
a plurality of the holders which are provided corresponding to the plurality of caps, individually; and
a support member which supports the plurality of holders.

3. The liquid ejecting apparatus according to claim 1 ,
wherein the cap is capable of moving between a capping position at which the closed space is formed and an open position which is separated from the capping position.

4. The liquid ejecting apparatus according to claim 1 , further comprising:
a carriage which reciprocates in a state in which the liquid ejecting head is mounted thereon; and
a support member which supports the holder,
wherein the cap moves along with the support member in conjunction with a movement of the carriage.

5. The liquid ejecting apparatus according to claim 1 , further comprising:
a support member which supports the holder; and
an urging member which is provided between the holder and the support member, and urges the cap in a direction of getting closer to the opening face through the holder.

6. The liquid ejecting apparatus according to claim 1 , further comprising:
a cap urging member which is disposed between the cap and the holder,
wherein the liquid ejecting head includes a side wall which extends in a direction which intersects the opening face,
wherein the cap includes a plurality of the engaging portions, and
wherein the cap urging member urges the cap in a direction in which the plurality of the engaging portions get closer to the side wall.

7. The liquid ejecting apparatus according to claim 6 , further comprising:
a second urging member which is disposed between the cap and the holder,
wherein, when the side wall is set to a first side wall, the engaging portion is set to a first engaging portion, and the cap urging member is set to a first urging member, the liquid ejecting head includes a second side wall which extends in a direction which intersects both of the opening face and the first side wall,
wherein the cap includes a plurality of second engaging portions, and
wherein the second urging member urges the cap in a direction in which the plurality of the second engaging portions get closer to the second side wall.

8. The liquid ejecting apparatus according to claim 1 ,
wherein the liquid ejecting head ejects the liquid in an ejecting direction, and
wherein the holder holds the cap, the cap being movable in the direction which goes along the opening face and tillable about the ejecting direction upon engagement of the cap with the liquid ejecting head.

9. The liquid ejecting apparatus according to claim 1 , wherein a plane along the surface of the liquid ejecting head different from the opening face intersects a plane along the opening face.

10. A liquid ejecting apparatus comprising:
a liquid ejecting head including a nozzle which ejects liquid, and an opening face to which the nozzle opens;
a cap which forms a closed space between the cap and the opening face, the cap including a plurality of the engaging portion that is capable of engaging with a surface of the liquid ejecting head different from the opening face; and
a holder which holds the cap,
wherein the cap rotates around an axis that intersects a plane along the opening face until the liquid ejecting head engages with one engaging portion and then engages with other engaging portion.

11. A liquid ejecting apparatus comprising:
a liquid ejecting head including a nozzle which ejects liquid, and an opening face to which the nozzle opens;
a cap which forms a closed space between the cap and the opening face, the cap including at least one engaging portion that is capable of engaging with a surface of the liquid ejecting head different from the opening face;
a holder which holds the cap, the cap being rotatable around an axis that intersects a plane along the opening face when the engaging portion engages with the liquid ejecting head; and
a spring urging member which urges the cap in a direction of getting closer to the opening face.
