Abstract

PURPOSE: To make a light reception element respond without time lag by arranging light emission and light reception elements both into a reflection type and by making a transparent substance semicircular.
CONSTITUTION: Light emission 1 and light reception element 2 are arranged on lead terminals 3 and 4. By transparent substance 5, both elements 1 and 2 are molded into a semicircle shape. Reflective coating 6 is formed covering transparent substance 5. By opaque container 7, reflective coating 6, and lead terminals 3 and 4 are molded. Light emitted from the light emission element is reflected at the interface between the reflective coating and transparent substance and then, reaches the light reception element directly, so the light reception element will respond to the light emission element without time delay
