    摘要： A sheet feeder includes a lift table, a first sheet-side restricting member, a second sheet-side restricting member, a suction conveyor, a rear-end restricting member, an upper distance-measuring sensor, a lower distance-measuring sensor, and processing circuitry. The first sheet-side restricting member and the second sheet-side restricting member restrict first ends and second ends opposite to the first ends, respectively, of sheets. The suction conveyor sucks and conveys a sheet floated. The rear-end restricting member restricts the sheets from moving in a longitudinal direction of the sheets. The upper distance-measuring sensor and the lower distance-measuring sensor measure a first distance and a second distance, respectively, to the first sheet-side restricting member or the second sheet-side restricting member. The processing circuitry compares measurement results of the first distance and the second distance to determine whether a distance between the first sheet-side restricting member and the second sheet-side restricting member is adequate.

    摘要： A sheet stacking device includes a sheet stacker, a pair of sheet restrictors, and a stacking adaptor. The sheet stacker has a first sheet stacking face on which a bundle of sheets is stacked. The sheet stacker includes a leading end support to support a leading end of the bundle of sheets in a feeding direction by a second sheet stacking face and a pair of cutouts disposed upstream from the leading end support. The pair of sheet restrictors slide in the pair of cutouts in a width direction orthogonal to the feeding direction to regulate a position of the bundle of sheets. The stacking adaptor is detachably attached to the sheet stacker to cover the pair of cutouts. The stacking adaptor has a third sheet stacking face to support a portion of the bundle of sheets disposed at the pair of cutouts.
