Abstract
PURPOSE:To perform an automatic and high-precise inspection of a relative position relation between perforations, by a method wherein parallel light is projected to each of a plural number of perforations in an object to be inspected to detect radiating light by a two-dimensional coordinate detector located facing and opposite to their respective perforations. CONSTITUTION:After an object 3 to be inspected is placed on a base stand 6, a casing 7 is lowered, light radiated from light sources 13a, 13b is produced into parallel light by lenses 11a, 11b, and enters 4-split semiconductors 16a, 16b after passing through axial holes 5a, 5b. The output signals SA-SD, SA'-SD' are inputted to an operational controller 25 through a preamplifier 22, a multiplexer 23, and an AD converter 24. From a ratio of a difference between two corresponding outputs to the sum of them, center coordinates (x1, y1), (x2, y2), for dividing a distance between output electrodes 21c, 21d and 21a, 21b into two equal parts, are found, a distance r, found from a square root of a square sum of an x- and a y-coordinate, is displayed in a display 26, and if it exceeds a reference value, it is unpassed. This allows to perform an automatic and high- precise inspection of relative position relation between perforations.
