摘要

PROBLEM TO BE SOLVED: To easily recognize visually an image pickup position in the case of focusing by irradiating an observed position of a printed circuit board being an object with a red visual layer beam. SOLUTION: A printed circuit board inspection device 25 supports a camera 2 with a support section 26 slidably in the vertical direction with an operation knob 27 and a magnified video image of the printed circuit board 50 being an inspection object placed on an inspection object placing base 24 is displayed on a display section 5 consisting of a CRT. A fluorescent light 11 is fitted to a tip of a camera 2 to light an observed position. An optical pointer 3 provides an output of the red visual layer beam, which penetrates a throughhole 12 of the fluorescent light 11 to irradiate an observed position of the printed circuit board 50 to indicate a marker indicating the image picked up position. The laser beam is in crossing obliquely with an optical axis of the camera 2 to be adjusted at a desired cross angle. For example, a magnification is set low to the camera 2 and at the camera position to focus the image pickup position, the marker is matched with the center of the image pickup range.
