METHOD FOR DETECTING DEVIATION OF PUNCHING POSITION OF PUNCH SHEET

摘要

PROBLEM TO BE SOLVED: To provide a method for detecting the deviation in punching position of a punch sheet in which a worker can correctly judge the deviation in the punching position. SOLUTION: In this method, a bar code 13 of a punch sheet whose image is picked up in a stopped condition is represented as a stationary image on a display screen 29 of an image processor 27, and the center of a box cursor 31c having the function of a two-dimensional cursor is set at the position at which the corner of the bar code 13 is displayed on the display screen 29 in a condition where no deviation is present in punching the punch sheet. When the deviation of the corner of the bar code 13 successively displayed on the display screen 29 from the center of the box cursor 31c is out of the allowable range, the deviation is judged to be rejected.
