Paper sheet binding apparatus

Abstract

According to one embodiment, a paper sheet binding apparatus includes a pressing member( 1 ) that presses object to be bound(T′) with a plurality of paper sheets stacked in a stacking direction of the paper sheets to move the object to be bound in the stacking direction, a feed unit( 20 ) that feeds a binding belt(f) in a direction orthogonal to the stacking direction ahead of a moving direction of the object to be bound, a press member( 3,4 ) that folds the binding belt along a back end in the moving direction of the object to be bound which is pressed by the pressing member and around which the binding belt is wound while pressing the back end of the object to be bound, and a welding and cutting unit( 7 ) that welds the folded binding belts with each other and cuts the same.

1 . A paper sheet binding apparatus, comprising:
 a pressing member that presses an object to be bound with a plurality of stacked paper sheets in a stacking direction of the paper sheets to move the object to be bound in the stacking direction;   a feed unit that feeds a binding belt in a direction orthogonal to the stacking direction ahead of a moving direction of the object to be bound;   a press member that folds the binding belt along a back end of the moving direction of the object to be bound which is pressed by the pressing member and around which the binding belt is wound, and presses the back end of the object to be bound; and   a welding and cutting unit that welds the folded binding belts with each other and cuts the binding belts.   
     
     
         2 . The paper sheet binding apparatus of  claim 1 , wherein
 the pressing member comprises a fixed pressing member and a movable pressing member movable with respect to the fixed pressing member, and the movable pressing member is arranged so as to be pressed down by the pressing member in a state of pressing the back end.   
     
     
         3 . The paper sheet binding apparatus of  claim 1 , wherein
 the welding and cutting unit is provided in the press member.   
     
     
         4 . The paper sheet binding apparatus of  claim 3 , wherein
 the welding and cutting unit comprises two pressing members separately arranged along the binding belt and a welding member that welds the binding belts with each other between the two pressing members.   
     
     
         5 . The paper sheet binding apparatus of  claim 1 , wherein
 a supporting member that supports the object to be bound is provided with a movable guide, and is arranged so as to be capable of holding a side surface of the object to be bound.
