  • Publication number: 20210107755
    Abstract: A sheet transport device includes a sheet storage unit that stores a sheet and that is disposed in a housing having a bottom plate such that a gap is provided between the sheet storage unit and the bottom plate, the gap extending horizontally; a sheet transport unit that feeds the sheet from the sheet storage unit and transports the fed sheet along a transport passage including a reversing transport path along which the sheet is transported downward and then upward to reverse the sheet front to back, the reversing transport path extending vertically and being connected to the gap; and a first gate unit that prevents passage of the sheet that has entered the reversing transport path when the sheet free falls and allows passage of the sheet when the sheet receives a sheet transport driving force from the sheet transport unit.

  • Publication number: 20210107306
    Abstract: A sheet tray includes a sheet storage unit that stores a sheet, the sheet storage unit being capable of being pulled out of a housing in a forward direction and pushed into the housing in a rearward direction to a position such that a gap is provided below the sheet storage unit; and a sheet moving portion fixed to the sheet storage unit, the sheet moving portion moving together with the sheet storage unit when the sheet storage unit is pulled out, thereby moving a sheet that has entered the gap in the forward direction.

  • Publication number: 20210094783
    Abstract: An image forming apparatus includes a drawer unit, a sheet inverting unit, a sheet guide plate, and a projection. The drawer unit is drawable from an apparatus body. The sheet inverting unit is disposed in the apparatus body, and pulls a sheet into a lower portion of the drawer unit to invert the sheet. The sheet guide plate is disposed on the sheet inverting unit to face the drawer unit, and includes a recess extending in a pull-out direction of the drawer unit that crosses a direction in which the sheet is transported. The projection protrudes toward the recess from a portion of a lower surface of the drawer unit facing the sheet guide plate near a pull-out start point in the pull-out direction and on a rear of a transport area of the sheet.

  • Patent number: 9738474
    Abstract: An orientation correcting device includes a first transporting unit that nips and transports a sheet; a detecting unit that detects a tilt of the sheet that is transported by the first transporting unit; a second transporting unit that nips and transports the sheet that has been transported by the first transporting unit; a flexure forming unit that, with the second transporting unit stopped, forms a flexure in the sheet as a result of causing the sheet that is transported by the first transporting unit to strike against the second transporting unit; and a moving unit that, with the second transporting unit stopped and the flexure formed in the sheet by the flexure forming unit, moves the second transporting unit in a crossing direction that crosses a transport direction of the sheet in accordance with an amount and a direction of the sheet tilt detected by the detecting unit.
