受光ヘツド。[Claims for Utility Model Registration] Two parallel light guides 18, 20 and one prism 2 in a single casing to form a light path from the light beam inlet 36/38 to the light beam outlet 38/36.
4 are disposed, and the end face 26 of one of the light guides and the end face 28 of the prism facing it are spaced apart in the optical axis direction to form an optical path defective portion 30, and a portion of the casing corresponding to the optical path defective portion is formed. In the light transmitting/receiving head 10 of an optical smoke concentration sensor for an internal combustion engine, the optical path cutout 30 is provided with a transverse cutout 32 so that internal combustion engine exhaust gas can pass across the cutout. heater element 42
The heater element has a ceramic body 44 consisting of a pair of cylindrical heads 46, 48 spaced apart in the optical axis direction and a connecting part 50 connecting them, each head having a at least one notch 52/54 passing through the head; a heating resistance wire 58 printed and routed to the outer end face 56/60 of the head;
6/60 is sandwiched between a light guide 18 and a prism 24 such that the light guide 6/60 is in close contact with the end faces 26, 28 of the one light guide and the prism.
