  • Publication number: 20160176211
    Abstract: An inkjet recording apparatus includes a control section, a conveyance section, a recording head, a gap forming section, and a negative pressure applying section. The gap forming section is disposed upstream of the recording head in a conveyance direction of a recording medium to form a narrow gap with a conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. The control section adjusts a distance across the narrow gap in the direction perpendicular to the conveying surface to a first distance in image formation. Upon receiving an instruction to clean the gap forming section, the control section adjusts the distance across the narrow gap in a direction perpendicular to the conveying surface to a second distance that is greater than the first distance and causes the negative pressure applying section to start applying negative pressure to the narrow gap.

  • Publication number: 20160159114
    Abstract: An inkjet recording apparatus includes a recording head, a conveyance section, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium placed on a conveying surface thereof to the recording head. The negative pressure applying section includes an airflow chamber and causes the recording medium to be sucked onto the conveying surface by negative pressure through holes in an upper wall of the airflow chamber and holes in the conveying surface. Negative pressure applied through first holes in a first region is greater than that applied through second holes in a second region. The first region is located upstream of a head facing region in a conveyance direction of the recording medium. The second region is located downstream of the first region in the conveyance direction of the recording medium and includes the head facing region.

  • Publication number: 20160129712
    Abstract: An inkjet recording apparatus includes a recording head, a conveyance section, a plate member, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium to a position of image forming by the recording head and has a conveying surface on which the recording medium is to be placed. The plate member is located upstream of the recording head in a conveyance direction of the recording medium to form a narrow gap with the conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. A distance across the narrow gap in a direction perpendicular to the conveying surface is set so as to allow air flowing into the narrow gap from surrounding space to have a higher flow velocity in the narrow gap than before flowing into the narrow gap.

  • Patent number: 8646774
    Abstract: A sheet transport device includes a registration section, a first sheet transport path and a second sheet transport path the two transport directions of which are substantially perpendicular to the sheet transport direction of the registration section, a confluence transport path, and a first guide member. The confluence transport path merges the first sheet transport path and the second sheet transport path. The first guide member may rotate toward the first sheet transport path when the sheet is fed from the first sheet transport path to the confluence transport path. The first guide member may rotate toward the second sheet transport path when the sheet is fed from the second sheet transport path to the confluence transport path.

  • Patent number: 8573587
    Abstract: A sheet material feeding device includes a send-out means that is pressed to contact with the uppermost surface of the sheet material stacked on the sheet material stacking member to move the contact surface in a predetermined direction for sending out the sheet material, a lift up/down means that moves the sheet material stacking member between a feeding position and a separate position, a member to be detected that can move in the up and down direction when the sheet material stacking member moves, a detecting member that can output a detection signal when the member to be detected moves to a predetermined position, and a cassette that supports the sheet material stacking member and can be attached and detached from an apparatus main body. The cassette has an engaging portion for moving the member to be detected to the predetermined position when being attached to the apparatus main body.
