Abstract

PURPOSE: To enhance the S/N by providing a cylindrical lens on the array light receiving surface so that the focal faces of the cylindrical lens may coincide substantially with each other.
CONSTITUTION: Positive cylindrical lens 5 is provided in front of a primary array 3 so that the bus may be parallel to x axis. Stop 6 is provided near image forming lens 2 along with a circular aperture. Then lens 5 is located so as to form the image of stop 6 on the receiving surface of array 3, and the luminous flux of area AA' corresponding to the aperture of lens 5 is put into the element of array 3. Accordingly, the luminous flux increases by an amount equivalent to the ratio between the size of array 3 in the direction y and the width of lens 5. Thus the sensitivity can be increased.
