Abstract: A wiping device includes a wiping member and a moving part. The wiping member wipes a liquid off a nozzle surface of a recording head. The moving part moves the wiping member along the nozzle surface in a predetermined moving direction. The wiping member performs a first wiping operation in which the wiping member is moved while not coming into contact with the nozzle surface but coming into contact with the liquid adhering to the nozzle surface, and a second wiping operation in which the wiping member is moved while coming into contact with the nozzle surface after the first wiping operation.

Abstract: A laser scanning unit includes a rotary polygon mirror, a shaft support portion, a plurality of light application portions, and a plurality of scanning lenses. The plurality of light application portions are configured to cause light beams to be incident at a plurality of incidence positions different in an axial direction parallel to the rotary shaft on the rotary polygon mirror. In the laser scanning unit, the following relationship is satisfied: when, of the plurality of light beams, a specific light beam incident at the incidence position that is most distant from the shaft support portion on the rotary polygon mirror passes through an optical axis of the corresponding scanning lens, an angle between the specific light beam incident on the rotary polygon mirror and the optical axis of the scanning lens is closest to a reference angle defined in advance as a usage condition of the scanning lens.

Abstract: An optical scanning apparatus includes a reflecting mechanism, a light receiving element and a restricting mechanism. The reflecting mechanism reflects a light beam such that the irradiation point of the light beam moves in a predetermined scanning direction. The light receiving element is arranged in a movement plane defined by the light beam reflected by the reflecting mechanism, and the light receiving element outputs a light reception signal for adjusting the irradiation timing of the light beam in accordance with reception of the light beam reflected by the reflecting mechanism. The restricting mechanism positions the light receiving element relative to the movement plane.

Abstract: The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.

Abstract: An inkjet recording apparatus includes a recording head, a wiper member, a cleaning liquid supply device, a cleaning liquid flow path, and a controller. The cleaning liquid flow path includes a vertical tubular member connected to the cleaning liquid supply device and extending upward, and a horizontal tubular member connected to an upper end of the vertical tubular member and extending in a horizontal direction. The controller extrudes a cleaning liquid in at least a part of the cleaning liquid flow path from a cleaning liquid supply port before control of a cleaning operation for wiping an ink ejection surface of the recording head, thereby performing control of an air bubble release operation of the cleaning liquid flow path.
