Abstract
According to one embodiment, a sheet stacking apparatus comprises a conveyance path, a plurality of stackers, a plurality of gates, a skew sensor, and a control unit. The gates are arranged in a number corresponding to the number of stackers, and guide the sheets from the conveyance path into the stackers, respectively. The skew sensor detects the skew of the sheet conveyed along the conveyance path. The control unit drives a gate corresponding to a stacker, in which the sheet is to be stacked, in accordance with the skew value of the sheet detected by the skew sensor upstream of the gate corresponding to the stacker, in which the sheet is to be stacked, in the direction in which the sheet is conveyed along the conveyance path.

A sheet stacking apparatus comprising:
- a conveyance path which conveys sheets;
- a plurality of stackers which stack the sheets;
- a plurality of gates which are arranged in a number corresponding to the number of stackers and which guide the sheets from the conveyance path into the stackers, respectively;
- a skew sensor which detects a skew of the sheet conveyed along the conveyance path;
- and
- a calculation unit which calculates a predicted skew value when the sheet reaches the gate corresponding to the stacker in which the sheet is to be stacked, based on the skew of the sheet detected by the skew sensor upstream of the gate corresponding to the stacker in which the sheet is to be stacked;
- a control unit which controls driving of the gate corresponding to the stacker in which the sheet is to be stacked, based on the predicted skew value calculated by the calculating unit.
A sheet stacking apparatus comprising:
- a conveyance path which conveys sheets;
- a plurality of stackers which stack the sheets;
- a plurality of gates, the plurality of gates respectively corresponding to the plurality of stackers, and each gate guiding selected sheets from the conveyance path into the corresponding stacker;
- a skew sensor arranged along the conveyance path at a location upstream and at a distance from at least one gate of the plurality of gates and the stacker corresponding to the one gate, the skew sensor respectively detecting skews of the sheets conveyed along the conveyance path;
- a calculation unit calculating a predicted skew value for each sheet when each sheet reaches the one gate and the corresponding stacker in which the selected sheets are to be stacked, based on the skew for each sheet detected by the skew sensor;
- and
- a control unit driving the one gate corresponding to the stacker in which the selected sheets are to be stacked, based on the predicted skew value for each sheet calculated by the calculating unit.
