Abstract
PURPOSE:To enable accurate marking in a marking machine with punching holes by detecting the holes by an adjacent photoelectric sensor, comparing its amplified value coincident point with a reference signal generating time point and controlling the speed of the machine. CONSTITUTION:A reference signal generator 20 receives light passed through arbitrary hole 5 of a disc 4 rotating synchronously with a hole punching machine at adjacent photodetectors 7a, 7b, detects the coincident point by a subtractor 22 through amplifiers 21a, 21b, respectively, and outputs a reference signal P from a monostable multivibrator 23 at the time point X. On the other hand, a mark position detector 24 similarly detects the hole B of a sheet A to be printed via photodetectors 11a, 11b, amplifies the lights, stores them in memory circuits 26a, 26b at the signal P generating time point X, applies a difference signal Q from the subtractor 27 to a comparator 30, which compares a pulse signal of the multivibrator 23 with a converted voltage signal to detect the delay speed, thereby controlling the rotating speed of a servo motor 12 through a drive circuit 31.
