Abstract
PURPOSE:To detect the position of a print resistance body even in the case of the contrast of the color on a work surface by the respective measurement result of a variable filter and fixed filter by dividing the reflection light from a work into two optical pathes. CONSTITUTION:A half mirror 13 is placed just before the filter of a detection optical system to divide a reflection light 32 in two optical pathes. Namely, it is divided into the optical path I detecting the brightness from a work 10 converted into the light strength in proportion to a light spot position via a variable filter 14 and the optical path II detecting via a fixed filter 15 only the brightness from the work 10. Since these optical path I, II includes the reflection, etc., from the surface of the work 10 as well the optical spot position detection signal only in proportion to the optical spot position is obtainable excluding the reflection, etc. from the surface of the work 10 by taking the ratio of the detection signal from the optical path I and that from the optical path II.
