ABSTRACT:
In a module which consists of optical systems and sensors, a pair of first line sensors are arranged vertically to a pair of second line sensors, and each of the line sensors is provided with a lens which projects an object image thereon. One of the first line sensors and one of the second line sensors intersect each other at right angles, and share an object lens which projects an object image onto them. In such a construction, the number of lenses, and the space for the line sensors are reduced, so that the module can be downsized.
