Abstract

A liquid ejecting apparatus includes a liquid ejecting head which ejects a liquid from a plurality of nozzles disposed on a nozzle surface; an absorbing member which makes contact with the nozzle surface and can absorb a liquid which is adhered to the nozzle surface; and a pressing member which causes the ink absorbing member to contact the nozzle surface by pressing the absorbing member from a side which opposes a side which contacts the nozzle surface. In the liquid ejecting apparatus, a pressure applied to a nozzle peripheral region within the nozzle surface due to the absorbing member which is pressed by the pressing member making contact with the nozzle surface is smaller than a pressure applied to a region other than the nozzle peripheral region within the nozzle surface.

Claims (43)

1. A liquid ejecting apparatus comprising:

a liquid ejecting head which ejects a liquid from a plurality of nozzles disposed on a nozzle surface;

an absorbing member configured to contact the nozzle surface and absorb the liquid adhering to the nozzle surface; and

a pressing member configured to press the absorbing member to bring the absorbing member into contact with the nozzle surface, wherein

the pressing member has an outer surface and a recessed portion that is recessed from the outer surface,

when the pressing member brings the absorbing member into contact with the nozzle surface, the outer surface brings the absorbing member into contact with a peripheral region other than a nozzle peripheral region where the nozzle is provided,

the pressing member has a cylindrical large-diameter portion that forms the outer surface and a cylindrical small-diameter portion that has a small diameter than the large-diameter portion and that forms the recessed portion.

2. The liquid ejecting apparatus according to claim 1 , wherein

the recessed portion is provided at a position corresponding to the nozzle peripheral region.

3. The liquid ejecting apparatus according to claim 1 , wherein

the absorbing member wipes the nozzle surface by moving in a wiping direction while the absorbing member is in contact with the nozzle surface,

the nozzle surface has the peripheral region sandwiching the nozzle peripheral region in an intersecting direction intersecting the wiping direction,

the outer surface brings the absorbing member into contact with the peripheral region.

4. The liquid ejecting apparatus according to claim 1 , wherein

a pressure exerted on the nozzle surface from the absorbing member due to the recessed portion of the pressing member is smaller than a pressure exerted on the nozzle surface from the absorbing member due to the outer surface of the pressing member.

5. The liquid ejecting apparatus according to claim 1 , wherein

the nozzle surface has a nozzle forming surface on which the nozzle is formed, and a cover that covers the nozzle forming surface,

the cover is provided with an opening for exposing the nozzle,

the recessed portion is provided at a position corresponding to the opening.

6. The liquid ejecting apparatus according to claim 5 , wherein

when the pressing member brings the absorbing member into contact with the nozzle surface, the outer surface brings the absorbing member into contact with the peripheral region of the nozzle surface other than the opening.

7. A liquid ejecting apparatus comprising:

a liquid ejecting head which ejects a liquid from a plurality of nozzles disposed on a nozzle surface;

an absorbing member configured to contact the nozzle surface and absorb the liquid adhering to the nozzle surface; and

a pressing member configured to press the absorbing member to bring the absorbing member into contact with the nozzle surface, wherein

the pressing member has an outer surface and a recessed portion that is recessed from the outer surface,

when the pressing member brings the absorbing member into contact with the nozzle surface, the outer surface brings the absorbing member into contact with a peripheral region other than a nozzle peripheral region where the nozzle is provided, and a pressing member side of the absorbing member is further from the nozzle surface at the nozzle peripheral region than the peripheral region.

8. The liquid ejecting apparatus according to claim 7 , wherein

the recessed portion is provided at a position corresponding to the nozzle peripheral region.

9. The liquid ejecting apparatus according to claim 7 , wherein

the absorbing member wipes the nozzle surface by moving in a wiping direction while the absorbing member is in contact with the nozzle surface,

the nozzle surface has the peripheral region sandwiching the nozzle peripheral region in an intersecting direction intersecting the wiping direction,

the outer surface brings the absorbing member into contact with the peripheral region.

10. The liquid ejecting apparatus according to claim 7 , wherein

the pressing member has a cylindrical large-diameter portion that forms the outer surface and a cylindrical small-diameter portion that has a small diameter than the large-diameter portion and that forms the recessed portion.

11. The liquid ejecting apparatus according to claim 7 , wherein

a pressure exerted on the nozzle surface from the absorbing member due to the recessed portion of the pressing member is smaller than a pressure exerted on the nozzle surface from the absorbing member due to the outer surface of the pressing member.

12. The liquid ejecting apparatus according to claim 7 , wherein

the nozzle surface has a nozzle forming surface on which the nozzle is formed, and a cover that covers the nozzle forming surface,

the cover is provided with an opening for exposing the nozzle,

the recessed portion is provided at a position corresponding to the opening.

13. The liquid ejecting apparatus according to claim 12 , wherein

when the pressing member brings the absorbing member into contact with the nozzle surface, the outer surface brings the absorbing member into contact with the peripheral region of the nozzle surface other than the opening.
