(57) According to an embodiment, a paper sheet processing apparatus includes a stacking
device which stacks paper sheets and a wrapping device which wraps a stacked paper
sheet bundle by winding a band thereon. The wrapping device includes a band winding
device which winds the band on the stacked paper sheet bundle and tightens it, a hand
assembly (96) which grasps the stacked paper sheet bundle by holding an end thereof,
a hand assembly drive mechanism (98) which draws the bundle to an arbitrary position
by reciprocating the hand assembly in a direction perpendicular to the bundle stacking
direction, detectors (118a, 118b, 118c) which detect a plurality of drawn-in positions
of the hand assembly, and a control unit which stops the hand assembly at an arbitrary
drawn-in position detected by the detectors and adjusts a band winding position on
the bundle.
