| (54) | Sheet material stacking apparatus and method of stacking sheet material |
| (57) The present invention provides a sheet material stacking apparatus (100) that includes
a sheet material stacking base (102) on which sheet materials (49) induced by a sheet
material conveying unit (36) are stacked, a first guide member (122A) disposed along
the conveyance direction of the sheet materials to the sheet material stacking base
(102) and sorts the end surfaces at one end with respect to the width direction (W)
thereof, a second guide member (122B) which is disposed in parallel and opposite to
the first guide member (122A) having the sheet material stacking base (102) therebetween,
a pusher (126A) that constitutes at least a portion of the first guide member (122A)
and is displaced between a reference position in which the distance (D) to the second
guide member (122B) is equal to the width of the sheet material and a separating position
in which the distance to the second guide member is larger than the width of the sheet
material, and a driving unit (136) that displaces the pusher (126A) and places side
by side both ends of the sheet materials (49) in the axis direction.
