Abstract

PURPOSE: To improve dielectric strength between input side and output side without increasing the space between the light emitting device and photo detector but by increasing the distance of the interface between the transparent resin and opaque resin across the luminous side frame to the light receiving side frame.
CONSTITUTION: Increase the distance of the interface from the transparent resin 14 to opaque resin 15 across the luminous side frame to the light receiving side frame without increasing the space between light emitting device 12 and photo detector 22, thus increasing the dielectric strength between input and output.
