PROBLEM TO BE SOLVED: To provide a method for displaying a main spindle processing a printed circuit board capable of easily identifying the main spindle processing the printed circuit board. SOLUTION: In this method for displaying a main spindle processing a printed circuit board to process an identification hole for identifying the main spindle on the printed circuit board, a number of identification holes Hi to be processed is varied every main spindle 6i. In this manner, the processed main spindle can be identified at a glance by counting the number of the identification holes Hi processed on the printed circuit board 9. Also, a diameter of the identification hole need to have a visually identifiable size, so that a processing area of the identification hole Hi can be made small. COPYRIGHT: (C)2008,JPO&INPIT
