摘要： A sheet stacking device includes sheet stacking portion, electric motor, current detecting portion, abnormality determining portion, and updating portion. The sheet stacking portion is supported to be movable in up-down direction and configured to stack sheets thereon. The electric motor outputs, to the sheet stacking portion, a driving force for moving the sheet stacking portion in up-down direction. The current detecting portion detects a current value of the electric motor. The abnormality determining portion determines that the sheet stacking portion is in abnormal state when the detected current value is greater than a predetermined threshold. The updating portion updates the threshold based on the current value that was detected by the current detecting portion while the sheet stacking portion with a predetermined set amount of sheets stacked thereon was being moved by the driving force received from the electric motor.

摘要： A sheet feeding apparatus includes a containing unit, a lifting and lowering unit, a loosening unit, a feed unit, a sheet-surface detection unit, an aligning member, a trailing-edge detection unit, a double-feed detection unit, and a control unit. Sheets, of a sheet bundle contained in the containing unit and lifted and lowered, are loosened by blowing air into the sheet bundle and fed. An end face of the contained sheet bundle is aligned on a trailing-edge side. The trailing-edge detection unit moves with the aligning member and detects a sheet surface of a top of the sheet bundle on the trailing-edge side. Where double feed from the containing unit is detected, a detection operation detects, in consideration of a trailing-edge detection unit result, whether the aligning member is located at a position at which the end face of the sheet bundle on the trailing-edge side is aligned.
