    摘要: A sheet feeder includes a stacker, a sheet feeding member, an aligner, a switcher, a size specifying unit, and circuitry. The sheet feeding member contacts and feeds a sheet stack on the stacker. The aligner is movable to align a position in a sheet width direction of the sheet stack on the stacker. The switcher switches the aligner from a separation state to a contact state without waiting for a feeding start instruction after the sheet stack is stacked on the stacker. The circuitry delays a switching completion time when the size in the sheet width direction of the sheet stack specified by the size specifying unit is smaller than a given size, to be later than the switching completion time when the size in the sheet width direction of the sheet stack is equal to or greater than the given size.

    摘要: Provided is a sheet storage apparatus including: an apparatus body; a sheet storage section; a top cover; a sheet feeding section; a restricting cursor; a blowing device; a sheet holding-down member; and a moving mechanism. The sheet storage section includes a sheet supply port, and a sheet stacking portion. The top cover is pivotable to an opening position and to a closing position. The blowing device includes a fan and a vent. The sheet holding-down member includes a restricting piece. The moving mechanism is coupled to the sheet holding-down member, moves the sheet holding-down member to a restricting position by coming into contact with the top cover under a state in which the top cover has come to the closing position, and moves the sheet holding-down member to a retracted position by separating from the top cover when the top cover is moved to the opening position.
