Abstract

PURPOSE:To achieve an accurate irradiation and detection of reflected light by providing a mask in a lighting optical system of an inspection head covering a lighting source to form a slit exposure window in such a manner as to be linear at the position of closely approaching a panel surface. CONSTITUTION:A panel 14 such as offset printing plate is placed on a punching plate 13 and an optical inspecion head 10 is reciprocated to measure the area of a patter. At this point, the inspection head 10 is provided with a mask 30 covering two linear lighting sources 23 in such a manner that it is formed having a curved section 31 with a reflecting surface and a liner section 32 with a non- reflecting surface at the position of closely approaching the panel 14. Then, a slit exposure is performed while a reflected light is received with a sensor 27 of light shielding boxes 26 arranged in a line. This enables accurate irradiation of an irradiating light in the detection area of the panel 14 while performing accurate detection of the reflected light thereby improving the accuracy.
