Abstract

Abstract An ink jet recording apparatus includes a recording head (111) including a liquid passage (107) having an ejection energy generating element for generating energy for ejecting ink, an ejection outlet (108) defining member having an ejection outlet communicating with the liquid passage (107), the ejecting outlet (108) defining member having a surface from which the ink is ejected through the ejection outlet (108), and a member (109) covering at least a part of the surface away from the ejection outlet (108); a wiping member for contacting the surface to wipe it; a driver for imparting relative movement between the surface and the wiping member to wipe the surface; and a controller for providing a relatively low speed of the relative movement at least when the surface being wiped by the wiping member.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 123 words
An ink jet recording apparatus, comprising: a recording head including a liquid passage having an ejection energy generating element for generating energy for ejecting ink, an ejection outlet defining member having an ejection outlet communicating with the liquid passage, said ejecting outlet defining member having a surface from which the ink is ejected through the ejection outlet, and a member covering at least a part of the surface away from the ejection outlet; a wiping member for contacting said surface to wipe it; means for imparting relative movement between said surface and said wiping member to wipe said surface; and control means for providing a relatively low speed of the relative movement at least when said surface being wiped by said wiping member.
Claim 2
Dependent Claim 123 words
An ink jet recording apparatus, comprising: a recording head including a liquid passage having an ejection energy generating element for generating energy for ejecting ink, an ejection outlet defining member having an ejection outlet communicating with the liquid passage, said ejecting outlet defining member having a surface from which the ink is ejected through the ejection outlet, and a member covering at least a part of the surface away from the ejection outlet; a wiping member for contacting said surface to wipe it; means for imparting relative movement between said surface and said wiping member to wipe said surface; and control means for providing a relatively low speed of the relative movement at least when said surface being wiped by said wiping member.
Claim 3
Dependent Claim 29 words
An apparatus according to Claim 1, wherein said wiping member has a first wiping member for wiping said surface and a second wiping member for wiping said covering member.
Claim 4
Dependent Claim 34 words
An apparatus according to Claim 2, further comprising supporting means for supporting said first wiping member movable between a first position for contact with said surface and a second position out of contact therewith.
Claim 5
Dependent Claim 64 words
An apparatus according to Claim 3, further comprising means for confining a wiping direction of said wiping means so as to wipe in a direction from a side of said ejection outlet in which a distance between said ejection outlet and said covering member is small to a side thereof in which the distance between said ejection outlet and said covering member is large.
Claim 6
Dependent Claim 27 words
An apparatus according to Claim 1, 2, 3 or 4, wherein said ejection energy generating element includes an electrothermal transducer for producing thermal energy as said energy.
