  • Patent number: 12109818
    Abstract: A recording apparatus includes a wiper, a recording head having a step portion and an ejection port surface supporting an ejection port, and a moving unit to relatively move the wiper and the recording head so that the wiper moves with respect to the recording head in relative movement in a first direction. In a first wiping, the relative movement causes the wiper to stop at or in vicinity of the step portion, or pass at or in the vicinity of the step portion at a speed lower than a speed at which the wiper wipes an area in which the ejection port is arranged. In a second wiping performed after the first wiping, the relative movement causes the wiper to pass through the step portion of the recording head and wipe the recording head in the first direction toward the area, and thereafter wipe the area.

  • Patent number: 12083800
    Abstract: A recording apparatus includes a recording head having an ejection port surface and a step portion, a blade to wipe the ejection port surface, and a moving unit. A plurality of ink ejection ports is arranged on the ejection port surface. The moving unit performs relative movement of the blade and the recording head by moving the blade or the recording head in a first direction to cause the blade to wipe a wiped surface including the ejection port surface, from the step portion to an area in which the plurality of ink ejection ports is arranged. The moving unit performs the relative movement so that a first relative velocity of the relative movement when the blade passes the step portion is higher than a second relative velocity of the relative movement when the blade, that has been in contact with the wiped surface, is separated from the wiped surface.

  • Patent number: 12067736
    Abstract: A unit derives displacement amounts of feature points in an entire region of a face shape. A unit derives separated displacement amounts, each of which is a displacement amount of each feature point for every deformation pattern of a partial region of the face shape, based on the displacement amounts of the feature points in the entire region of the face shape and deformation degrees for every deformation pattern of the partial regions. A unit derives normalized and separated displacement amounts, which are obtained by normalizing the separated displacement amounts, for every deformation pattern of the partial regions. A unit generates weight values of the feature points in the entire region of the face shape based on the normalized and separated displacement amounts for every deformation pattern of the partial regions of the face shape and the deformation degrees for every deformation pattern of the partial regions.
