    摘要: Provided is a sheet stacking apparatus including an aligning member lifting-lowering device configured to lift and lower aligning members between an aligning position where the aligning members abut to and align the sheets and a retreating position where the aligning members are lifted from an upper surface of the sheets, an aligning member moving device configured to move the aligning members in a sheet width direction, and a stack tray lifting-lowering device configured to lift and lower a stack tray based on a detection result of a sheet surface detecting device. A controller lifts the aligning members to the retreating position with the aligning member lifting-lowering device after the sheets stacked on the stack tray is aligned at the aligning position, and stops lifting-lowering operation of the stack tray lifting-lowering device while the aligning members are moved in the sheet width direction with the aligning member moving device.

    摘要: A conveying roller conveys a sheet. A sheet holding portion receives a sheet from below and holds the received sheet with keeping its forward end upward and its rear end downward. The sheet holding portion has: a storing guide provided in a vertical state and having a guide surface configured to guide the received sheet upward; a conveying guide provided to face the guide surface and having a curved surface portion whose distance from the guide surface increases in the upward direction; and a holding member provided between the guide surface and the curved surface portion and configured to roll on the curved surface portion toward the guide surface to nip the received sheet with the guide surface. An inclination angle of the curved surface portion with respect to the guide surface decreases with distance from the guide surface.

    摘要: A finisher 100 includes a pair of bundle discharge rollers 130, a lower stack tray 137, and a width-direction aligning portion 200. The width-direction aligning portion includes a pair of aligning members 1 and a driving motor. The aligning member includes a pair of first aligning members 91 that is rotatably supported while being movable in the sheet width direction orthogonal to the discharge direction and a pair of second aligning members 92. The driving motor rotates the pair of first aligning members and moves the pair of first aligning members in the width direction. When the pair of first aligning members rotates and one of the pair of second aligning members abuts on the sheet, the pair of second aligning members forms opposite surfaces in which the sheet can be aligned in the width direction, and the pair of first aligning members align the sheet by the opposite surfaces.

    摘要: This invention provides a sheet storage device, which can enhance sheet taking-out property in taking out of a sheet from a sorting device and sheet visibility. A sheet storage device 300 is equipped with sheet storage portions 330a to 330e which are provided in an upper portion of a copying machine body 130 and receive sheets P, conveyed in sequence from the copying machine body 130, from downward and store the sheets P in such a state that the sheets P stand. The sheet storage portions 330a to 330e are relatively rotatably supported in sequence and parallel. Each sheet storage portion receiving the sheet from the copying machine body 130 is rotated to be held in the rotational position. According to this constitution, the sheet taking-out property in taking out of the sheet from the sheet storage portions 330a to 330e and the sheet visibility are enhanced.

    摘要: To provide a sheet stacking apparatus and image forming system capable of improving alignment characteristics also in the case where an aligning section is not able to act on a sheet discharged onto a stacking tray, the sheet stacking apparatus and image forming system include a stacking tray stacking discharged sheets, a pair of aligning sections capable of shifting in a width direction to align the width direction crossing a direction in which the sheet to stack on the stacking tray is discharged, and a control section that controls a relative position of the aligning sections and the sheet to discharge so that one of the pair of the aligning sections regulates a shift of the sheet stacked on the stacking tray to one direction side in the width direction, when a sheet with a predetermined width in the width direction of the sheet is discharged to the stacking tray.
