Abstract
A post-processing apparatus that rotates a rotation paddle in which a fin having flexibility is cantilevered by a holder to apply a conveying force along a rotation direction to a sheet to align the sheet, wherein the holder includes a recess in which a peripheral surface part from a support position of the fin to an upstream side in the rotation direction is recessed from a circumscribed circle of the holder, and when the fin elastically turns while being pressed against the sheet with rotation of the rotation paddle, turning of the fin is allowed until the fin comes into contact with a surface of the recess.
Claims19
A post-processing apparatus that rotates a rotation paddle in which a fin having flexibility is cantilevered by a holder to apply a conveying force along a rotation direction to a sheet to align the sheet, wherein
- the holder includes a recess in which a peripheral surface part from a support position of the fin to an upstream side in the rotation direction is recessed from a circumscribed circle of the holder, and
- when the fin elastically turns while being pressed against the sheet with rotation of the rotation paddle, turning of the fin is allowed until the fin comes into contact with a surface of the recess.
A post-processing apparatus that rotates a rotation paddle in which a fin having flexibility is cantilevered by a holder to apply a conveying force along a rotation direction to a sheet to align the sheet, wherein
- a support recess that fixedly supports a base end part of the fin at a bottom part is provided on an outer peripheral surface of the holder, and when a part of a free end part of the fin existing in the support recess is defined as a first part, a side wall on an upstream side in the rotation direction of the support recess is separated from the first part of the fin to which no external force is applied to the upstream side in the rotation direction through a space, and
- when the fin elastically turns while being pressed against the sheet with rotation of the rotation paddle, turning of the fin is allowed until the first part of the fin comes into contact with the side wall of the support recess.
A rotation paddle that is used in a post-processing apparatus that aligns a sheet and applies a conveying force along a rotation direction to the sheet, the rotation paddle comprising:
- a fin having flexibility;
- and a holder that supports the fin in a cantilever manner, wherein
- the holder includes a recess in which a peripheral surface part from a support position of the fin to an upstream side in the rotation direction is recessed from a circumscribed circle of the holder, and
- when the fin elastically turns while being pressed against the sheet with rotation of the rotation paddle, turning of the fin is allowed until the fin comes into contact with a surface of the recess.
