Abstract
An inkjet printing apparatus includes: a print head having an ejection opening surface on which an ejection opening for ejecting ink is provided; a wiping unit configured to wipe the ejection opening surface; a moving unit configured to move the wiping unit in a first direction; and a treatment liquid holding portion having a holding member for holding a treatment liquid and an applying member for applying the treatment liquid to the wiping unit by coming into contact with the wiping unit, wherein a plurality of treatment liquid holding portions are arranged in a second direction crossing the first direction such that adjacent treatment liquid holding portions are not in contact with each other.
Claims14
An inkjet printing apparatus comprising:
- a print head having an ejection opening surface on which an ejection opening for ejecting ink is provided;
- a wiping unit configured to wipe the ejection opening surface;
- a moving unit configured to move the wiping unit in a first direction;
- and
- a plurality of treatment liquid holding portions each having a holding member for holding a treatment liquid and an applying member for applying the treatment liquid to the wiping unit by coming into contact with the wiping unit moved by the moving unit, the plurality of treatment liquid holding portions being arrayed in a second direction orthogonal to the first direction and a boundary between the adjacent applying members being inclined with respect to the first direction so that the adjacent applying members overlap each other in the second direction and in the first direction,
- wherein at least a part of the wiping unit is configured to have the treatment liquid applied from both of adjacent applying members by moving past the boundary in a case where the moving unit moves the wiping unit in the first direction.
A treatment liquid holding unit used for an inkjet printing apparatus including a print head having an ejection opening surface on which an ejection opening for ejecting ink is provided, a wiping unit configured to wipe the ejection opening surface, and a moving unit configured to move the wiping unit in a first direction, the treatment liquid holding unit comprising:
- a plurality of treatment liquid holding portions each having a holding member for holding a treatment liquid and an applying member for applying the treatment liquid to the wiping unit by coming into contact with the wiping unit moved by the moving unit, the plurality of treatment liquid holding portions being arrayed in a second direction orthogonal to the first direction and a boundary between the adjacent applying members being inclined with respect to the first direction so that the adjacent applying members overlap each other in the second direction and in the first direction,
- wherein at least a part of the wiping unit is configured to have the treatment liquid applied from both of adjacent applying members by moving past the boundary in a case where the moving unit moves the wiping unit in the first direction.
An inkjet printing apparatus comprising:
- a print head having an ejection opening surface on which an ejection opening for ejecting ink is provided;
- a wiping unit configured to wipe the ejection opening surface;
- a moving unit configured to move the wiping unit in a first direction;
- and
- a plurality of treatment liquid holding portions each having a holding member for holding a treatment liquid and an applying member for applying the treatment liquid to the wiping unit by coming into contact with the wiping unit moved by the moving unit,
- wherein the plurality of treatment liquid holding portions is arrayed in spaced-apart positions in a second direction orthogonal to the first direction, with each treatment liquid holding portion being separated in the second direction from an adjacent treatment liquid holding portion by an inclined boundary between adjacent treatment liquid holding portions,
- wherein the inclined boundary between adjacent treatment liquid holding portions is inclined with respect to the first direction so that the adjacent treatment liquid holding portions overlap each other in the second direction and in the first direction, and
- wherein at least a part of the wiping unit is configured to have the treatment liquid applied from both of adjacent applying members by moving past the inclined boundary in a case where the moving unit moves the wiping unit in the first direction.
