Binding processing device and image forming system

Abstract

A binding processing device includes: a binding processing unit that performs binding processing by moving binding teeth toward a paper bundle to apply pressure to the paper bundle; and a control unit that controls a movement of the binding processing unit, in which the control unit increases a pressure-applying force of the binding teeth in a case where movement of the binding teeth in the binding processing of the paper bundle does not reach a predetermined amount of movement.

What is claimed is: 
     
         1 . A binding processing device comprising:
 a binding processing unit that performs binding processing by moving binding teeth toward a paper bundle to apply pressure to the paper bundle; and   a control unit that controls a movement of the binding processing unit,   wherein the control unit increases a pressure-applying force of the binding teeth in a case where movement of the binding teeth in the binding processing of the paper bundle does not reach a predetermined amount of movement.   
     
     
         2 . The binding processing device according to  claim 1 ,
 wherein the control unit increases the pressure-applying force of the binding teeth in a case where the movement of the binding teeth does not reach a predetermined amount of movement in a predetermined time setting.   
     
     
         3 . The binding processing device according to  claim 2 ,
 wherein the control unit performs control to end the binding processing in a case where the movement of the binding teeth does not reach a predetermined amount of movement in a predetermined time setting, and increases the pressure-applying force of the binding teeth in a case where the control is performed a predetermined number of times.   
     
     
         4 . The binding processing device according to  claim 1 ,
 wherein the control unit sequentially increases the pressure-applying force of the binding teeth until a predetermined upper limit value is reached, and determines whether the movement of the binding teeth has reached the predetermined amount of movement.   
     
     
         5 . The binding processing device according to  claim 4 ,
 wherein the control unit controls the binding processing unit to perform the binding processing using the increased pressure-applying force as a new setting value in a case where the movement of the binding teeth has reached the predetermined amount of movement.   
     
     
         6 . The binding processing device according to  claim 1 ,
 wherein the control unit sets an amount of movement of the binding teeth based on information regarding the number of sheets to be bound in the paper bundle and a location where the binding processing is to be performed on the paper bundle, and   the pressure-applying force is increased by a predetermined amount of increase.   
     
     
         7 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to  claim 1  that binds the paper on which the image is formed by the image forming apparatus.   
     
     
         8 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to  claim 2  that binds the paper on which the image is formed by the image forming apparatus.   
     
     
         9 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to  claim 3  that binds the paper on which the image is formed by the image forming apparatus.   
     
     
         10 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to  claim 4  that binds the paper on which the image is formed by the image forming apparatus.   
     
     
         11 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to  claim 5  that binds the paper on which the image is formed by the image forming apparatus.   
     
     
         12 . An image forming system comprising:
 an image forming apparatus that forms an image on paper; and   the binding processing device according to claim  6  that binds the paper on which the image is formed by the image forming apparatus.
