Claim 14:
15. A method of operating a sheet stacker, comprising:
moving a sheet stacking portion in a stacking direction, the sheet stacking portion including a bundle of sheets stacked in the stacking direction;
regulating a position of the bundle of sheets in a width direction using a pair of sheet restrictors, the regulating including moving the pair of sheet restrictors in the width direction of the bundle of sheets orthogonal to the stacking direction;
feed a top sheet of the bundle of sheets at a sheet feeding position in a sheet feeding direction orthogonal to the stacking direction and the width direction using a sheet feeder, the sheet feeding position at a top of the bundle of sheets in the stacking direction; and
detect a position of the pair of sheet restrictors in the width direction using a position detector, the position detector between the pair of sheet restrictors in the width direction and above the sheet feeding position in the stacking direction, wherein
the position detector is attached to a stay, the stay at a center of the pair of sheet restrictors in the width direction and above the sheet feeding position.
