Light receiving device
专利汇可以提供Light receiving device专利检索，专利查询，专利分析的服务。并且PURPOSE:To extend the reaching distance of infrared rays, by providing a constitution wherein the back surface of an attaching part to which an infrared ray receiving element is attached is covered by a metal case and the front surface is opened, widening the incident angle to the light receiving element, and increasing the amount of the incident light. CONSTITUTION:A PIN photodiode 13 made of plastic mold, which is a infrared ray receiving element, is attached to the front surface of a printed substrate 11 in parallel with the substrate 11. Circuit parts constituting an amplifier are attached to the substrate at the same time. A plurality of projections 17, which are provided on a metal case 12, are inserted into holes 18 of the substrate 11 and soldered. Thus, only the back surface of the substrate 11 is covered by the case 12.，下面是Light receiving device专利的具体信息内容。
