ABSTRACT:
The apparatus includes a light source section, a recognizing section, a moving device, and an operating section. The light source section is disposed transversely of a board so as to illuminate one side of the board. The recognizing section includes lenses, which are disposed transversely of the board so as to face the board from an opposite side relative to the light source section. The recognizing section also includes line image sensors disposed transversely of the board for receiving light rays from the lenses. The moving device is operable to move both the light source section and the recognizing section without changing the relative positions of these sections but moves them in such a way as to change their respective positions relative to the board. The operating section is operable to calculate image data for the entire board from image information obtained by the recognizing section and from position information obtained by the moving device.
