Abstract

Staple removal equipment is provided. The staple removal equipment has a detecting unit which detects a position of a staple stapling a paper bundle, a striking portion which strikes the staple, and a removing unit which removes the staple from the paper bundle.

What is claimed is: 
     
         1 . Staple removal equipment comprising:
 a detector to detect a position of a staple stapling a paper bundle;   a striking portion to strike the staple; and   a removing unit to remove the staple from the paper bundle.   
     
     
         2 . The equipment according to  claim 1 ,
 wherein the removing unit includes an auxiliary roller to curve the paper bundle, a blade to rotate about a rotary shaft serving as a rotation center so as to remove the staple from the paper bundle, a pair of guide rollers to guide conveying of the paper bundle and to convey the paper bundle to an ink erasing device, and a collecting mechanism to collect the removed staple.   
     
     
         3 . The equipment according to  claim 2 , wherein the striking portion includes a striking block to strike the staple using an elastic member to be released from a compressed state so as to accelerate the striking block to strike the staple, a striking base to be provided at a position facing the surface of the striking block striking the staple and a sensor to detect an leading end of the paper bundle, and
 wherein the striking block strikes the staple in response to detection of the leading end of the paper bundle by the sensor.   
     
     
         4 . The equipment according to  claim 3 ,
 wherein the striking portion moves to a position detected by the detecting unit and strikes the staple.   
     
     
         5 . The equipment according to  claim 4 ,
 wherein the striking block is a tool steel and the elastic member is a spring.
