  • Patent number: 11906922
    Abstract: A sorting device includes a base portion and a tray portion. The tray portion is supported on the base portion to be reciprocatable between a first shift position, where the tray portion is located at one side in the sheet width direction, and a second shift position, where the tray portion is located at the other side in the sheet width direction. The tray portion has a cutout portion. The cutout portion is formed by cutting away, with a predetermined width, an end part of the tray portion in the sheet width direction inward across the tray portion. With the tray portion at the second shift position, the cutout portion is located below one side end edge of the sheet in the sheet width direction, of sheets stacked on the tray portion.

  • Patent number: 11427426
    Abstract: A sorting device is mounted, in an image forming apparatus, in a sheet discharge space open at its front and sheet-discharge-direction downstream side, insertably or extractably at the downstream side. The sorting device includes a base portion, a tray portion, and a flexible member. The base portion is mounted, with the tray portion, in the base portion. The base portion has, in its upstream part in sheet discharge direction, a base inclined portion inclined upward downstream. With the base portion mounted in the bottom portion, the base inclined portion faces, across a predetermined gap, a bottom inclined surface inclined upward downstream in discharge direction. The tray portion is supported on the base portion to be reciprocatable in sheet width direction orthogonal to discharge direction. The flexible member is fitted to the base inclined portion and fills the gap between the base inclined portion and the bottom inclined surface.

  • Patent number: 11415924
    Abstract: A sorting device includes a base portion, a tray portion, and a tray driving portion. The tray driving portion includes a motor, a supporting shaft, an input member, an output member, a link mechanism, and an urging member. The input member includes a first boss portion movably supported on the supporting shaft, and is reciprocatable up and down along the supporting shaft. The output member has a second boss portion coupled with the first boss portion via a ratchet mechanism. The link mechanism converts a rotary motion of the output member to a linear motion of the tray portion. The ratchet mechanism operates such that, when a predetermined or heavier load is applied to the output member via the tray portion, the input member is pushed down against the urging force of the urging member and engagement between the first and second ratchet teeth is released.
