Abstract: PURPOSE:To easily determine an optimum irradiation point of laser for a signal path with a simple constitution by providing a transparent reflective film for the one to be formed on a mounting print plate side surface of electrophoto- crystal arranged in contact with or in the vicinity of the signal path to detect signal wave on the mounting print plate. CONSTITUTION:A transparent reflective film 12 is provided for the one to be formed on a mounting print plate 1 side surface of a electrophoto-crystal 10. By introducing laser into the crystal 10, a part of it is irradiated on a print plate 1 through the reflective film 12. This laser is reflected on the surface of the print plate 1 and is introduced via the crystal 10, a light path separation means 8 and a detection means 16 into light detection means 17. If the laser is irradiated to a signal path 15 and its surroundings by scanning, the intensity of the laser reflected on the print plate 1 is different between the signal path 15 and its surroundings. By maintaining polarity of the laser reflected on the reflective film 12 without giving electric field to the photo-crystal 10 during the scanning of laser, an electric signal corresponding to the reflection intensity from the print plate 1 is obtained in the light detection means 17, and an optimum radiation point of laser is detected.
