摘要：<p>PURPOSE:To eliminate the control for the position of a masking member, by installing the masking member at the holding part of a reflecting member and a photoelectric transducer in a body. CONSTITUTION:A light receiving construction 10 of a unified frame mold form includes a reflecting member 11, a masking member 12, and a connecting member 13 which connects the members 11 and 12 together at a lower part. A light masking part 12a projected by a prescribed length is formed at the inside opposite to the member 11 at the upper part of the member 12, and a stage part 12b is formed at the outside of the construction 10 to hold a light masking member 18 of bottom part. A photometric photoelectric transducer 8 is provided in a body with an IC chip 7. The IC chip 7 is fitted to the constructuion 10 from the lower part to be held at a prescribed position by means of a positioning stage part 15a. Thus the phtoelectric transducer is positioned accurately and as prescribed to a reflective surface 11a and the part 12a.</p>
