PURPOSE: To improve performance by storing as sequential input movement of a first plate to be perforated and automatically feeding it for perforation according to the postsequence.
CONSTITUTION: A first substrate (a) is set on a moving table 8, and after a set key 21a of a change-over switch 21 is pressed, the moving table 8 is returned to zero point of a feed mechanism 10, and then a switch 24 is turned on to enter the coordinate position of the zero point into a memory 25 by linear scales 19, 19'. The moving table 8 is moved and the substrate (a) is displayed on a scope 4; whenever the substrate (a), enlarged mark (b) and register mark (b') come together, the table 8 is stopped, and a switch 6 is turned on to perforate the substrate (a) at every predetermined position by a drill 5' of a perforator 5.
