Description of the Related Art As is well known, an autofocus camera incorporates a passive autofocus module that couples a subject to a one-dimensional image sensor through a lens, processes the video signal, and measures the distance to the subject. Have been. 3 and 4 show an assembly structure of a conventional autofocus module. In the drawings, 1 is an autofocus IC, 2 is a pair of left and right separator lenses, and 3 is equipped with a separator lens 2 for autofocus. This is a light-shielding box combined with the light receiving surface side of IC1. In addition, the above-mentioned auto focus IC 1
In this example, an IC chip provided with a pair of photosensor arrays arranged in a straight line is accommodated in a clear mold or ceramic package 1a, and a light receiving window 1b is formed in the center of the upper surface of the package 1a. Reference numeral 1c denotes an external lead pulled out of the package 1a.
