PROBLEM TO BE SOLVED: To exactly perform punch hole detection and punching processing even without work for highly accurately matching the optical axis of a light emitter/receiver, the interval of the light emitter/receiver and a puncher and the axis of the puncher or the like. SOLUTION: The detection error of a punch hole is found by detecting the position of the punch hole on a first card for correction, on which the punch hole is opened at a specified position beforehand, (S31-S42), a punching error is found by punching a second card for correction at a specified position and detecting the position of that punch hole (S42-S62), the detected position of the punch hole on the card of a real processing object is corrected by this error information, and a target punching position is corrected. |
