    摘要： A sheet stacking device includes a pair of first sheet stackers, a pair of sheet alignment members, a second sheet stacker, a sheet removal portion, and control circuitry. The first sheet stackers stack both end portions of a sheet in a direction orthogonal to a sheet ejecting direction. The sheet alignment members contact both ends of the sheet in the orthogonal direction to align the sheet on the first sheet stackers. The second sheet stacker is disposed lower than the first sheet stackers and stacks the sheet dropped from between the first sheet stackers. The sheet removal portion is disposed on one side in the orthogonal direction. The control circuitry causes one of the first sheet stackers and one of the sheet alignment members to move toward an opposite side of the sheet removal portion in the orthogonal direction after the sheet is dropped from between the first sheet stackers.

    摘要： A CPU checks a detecting state of a document set sensor at a point when the trailing end of a document sheet is assumed to pass through a separating position at which the document sheet is separated by a separation roller, based on a document length determined based on a detecting output from an abutting sensor. If the document set sensor does not detect a document sheet, the CPU determines that the next document sheet is not present. If the document set sensor detects a document sheet, the CPU checks a detecting state of the document presence detecting sensor. If the document presence detecting sensor detects a document sheet, the CPU determines that the next document sheet is present.

    摘要： A sheet stacker includes a sheet ejector, a sheet stack portion, and air blowers. The sheet ejector ejects a sheet. The sheet stack portion stacks the sheet ejected by the sheet ejector. The air blowers blow air from blow ports toward the sheet ejected from the sheet ejector. Each of the air blowers includes an air generator, an air guide, a first blow portion, a second blow portion, and a switcher. The air generator generates the air. The air guide guides the air to each of the blow ports. The first blow portion blows the air toward the sheet. The second blow portion blows the air in a direction different from a direction in which the first blow portion blows the air. The switcher performs switching so that the air guide guides the air to one of the first blow portion and the second blow portion.
