Abstract

PURPOSE:To make accurate area measurement integrally with a printing line possible by processing the detection outputs of the reflected light of the light irradiated by two sets of light sources consisting of plural photodiodes on the substrate front side and spaced at prescribed distances from a printing surface by means of circuits including a multiplexer on the rear side. CONSTITUTION:If the position of a detecting head 10 is adjusted with guide rails and the like as a guide, the height (x) of two sets of symmetrical fluorescent lamps 11, 12 spaced by a distance (k) from the center of plural photodiodes S0- on the front side of the substrate of a head 10 from a printing plate 20 is made equal to the distance (k). By this adjustment, the illuminance change in accordance with position deviations owing to thermal strains and ruggednes during working of the plate 20 in an object inspection area P is made slight. hence, an amplifier group 41, a multiplexer 42, an A/D converter 44, an I/O controller 49, etc. provided on the rear side of the substrate of the head 10 are controlled by CPU44, by which the detection outputs of the diodes S0- are processed successively, and the prescribed operations are carried out. As a result, the pattern areas of various printing plates are accurately measured integrally with the printing line.
