Abstract

An inkjet recording apparatus includes a processing liquid head ejecting a processing liquid, an ink head ejecting an ink, a processing liquid wiper wiping the processing liquid head, an ink wiper wiping the ink head, and an ink container including a first opening receiving the ink. A movement range of the processing liquid wiper during the wiping is set to a position without a region directly above the first opening.

Claims (71)

1 . An inkjet recording apparatus, comprising:

a treatment liquid head configured to eject treatment liquid;

an ink head configured to eject ink;

a treatment liquid wiper configured to wipe the treatment liquid head;

an ink wiper configured to wipe the ink head;

an ink container with a first opening, the first opening being configured to receive the ink; and

a treatment liquid container with a second opening, the second opening being configured to receive the treatment liquid,

wherein a movement range of the treatment liquid wiper at a time of wiping is set at a position without a region directly above the first opening,

wherein the treatment liquid container is located at a position covering a part of an upper side of the first opening, and

wherein the movement range of the treatment liquid wiper at the time of wiping is set at a position directly above the second opening.

2 . The inkjet recording apparatus according to claim 1 ,

wherein the first opening and the second opening are located in series in a direction along a movement direction of the treatment liquid wiper at the time of wiping, and

wherein the movement direction of the treatment liquid wiper is set at a direction away from the first opening.

3 . The inkjet recording apparatus according to claim 2 , further comprising:

a cleaning area where the ink wiper is cleaned; and

a removal portion configured to remove ink adhering to the ink wiper or a support member thereof,

wherein in a movement direction of the ink wiper to the cleaning area, the second opening is located downstream of the first opening, and

wherein the removal portion is located upstream of the second opening.

4 . The inkjet recording apparatus according to claim 1 ,

wherein the treatment liquid wiper is configured to move along a predetermined movement path when wiping is performed, and

wherein an entirety of the movement path is set at a position without a region directly above the first opening.

5 . The inkjet recording apparatus according to claim 1 , further comprising a cleaning area where the treatment liquid wiper and the ink wiper are cleaned,

wherein in a movement direction from an area where wiping is performed to the cleaning area, the treatment liquid wiper is located at a position closer to the cleaning area than the ink wiper.

6 . The inkjet recording apparatus according to claim 1 , further comprising, a cleaning area where the treatment liquid wiper is cleaned,

wherein a movement direction of the treatment liquid wiper at the time of wiping is set at a direction in which the cleaning area is located.

7 . The inkjet recording apparatus according to claim 1 , further comprising a printing area where ink is ejected from the ink head to form an image,

wherein in a movement direction from the printing area to an area where wiping is performed, the treatment liquid wiper is located at a position closer to the printing area than the ink wiper.

8 . The inkjet recording apparatus according to claim 1 , further comprising a support plate configured to support the treatment liquid wiper and the ink wiper,

wherein in a shape of the support plate in a top view, a support region of the support plate, the support region being configured to support the treatment liquid wiper, protrudes in a movement direction at the time of wiping compared to other regions of the support plate.

9 . The inkjet recording apparatus according to claim 1 , further comprising a support plate configured to support the treatment liquid wiper and the ink wiper,

wherein in a shape of the support plate in a top view, the support plate includes a plurality of protruding portions each corresponding to a respective one of the treatment liquid wiper and the ink wiper, and

wherein the treatment liquid wiper and the ink wiper are located at a respective one of corresponding protruding portions.

10 . The inkjet recording apparatus according to claim 1 , further comprising a support plate configured to support the treatment liquid wiper and the ink wiper,

wherein in a shape of the support plate in a top view, the support plate comprises a plurality of protruding plates protruding in a movement direction at the time of wiping and recessed portions each between the protruding plates, and

wherein the treatment liquid wiper and the ink wiper are respectively located at an end edge of a protruding plate of the plurality of protruding plates or an end edge of a recessed portion of the recessed portions.

11 . The inkjet recording apparatus according to claim 1 ,

wherein the treatment liquid wiper and the ink wiper are different from each other in terms of shape or material.

12 . The inkjet recording apparatus according to claim 1 ,

wherein the ink wiper comprises an ink blade extending in a direction intersecting a movement direction at the time of wiping, and

wherein the ink blade is located to be inclined, and a first end portion on a side where the treatment liquid container is present protrudes in the movement direction compared to a second end portion on the opposite side of the first end portion.

13 . The inkjet recording apparatus according to claim 1 , wherein

the treatment liquid wiper comprises a treatment liquid blade extending in a direction intersecting a movement direction at the time of wiping, and

the treatment liquid blade is located to be inclined, and a third end portion on a side where the ink container is present protrudes in the movement direction compared to a fourth end portion on the opposite side of the third end portion.

14 . The inkjet recording apparatus according to claim 1 ,

wherein the treatment liquid head and the ink head are located at a position where the treatment liquid head and the ink head entirely overlap each other in a movement direction at the time of wiping.

15 . An inkjet recording apparatus, comprising:

a treatment liquid head configured to eject treatment liquid;

an ink head configured to eject ink;

a treatment liquid wiper configured to wipe the treatment liquid head;

an ink wiper configured to wipe the ink head;

an ink container with a first opening, the first opening being configured to receive the ink; and

a cleaning area where the treatment liquid wiper and the ink wiper are cleaned,

wherein a movement range of the treatment liquid wiper at a time of wiping is set at a position without a region directly above the first opening, and

wherein in a movement direction from an area where wiping is performed to the cleaning area, the treatment liquid wiper is located at a position closer to the cleaning area than the ink wiper.

16 . The inkjet recording apparatus according to claim 15 ,

wherein the treatment liquid wiper is configured to move along a predetermined movement path when wiping is performed, and

wherein an entirety of the movement path is set at a position without a region directly above the first opening.

17 . An inkjet recording apparatus comprising:

a treatment liquid head configured to eject treatment liquid;

an ink head configured to eject ink;

a treatment liquid wiper configured to wipe the treatment liquid head;

an ink wiper configured to wipe the ink head;
