<p>PURPOSE:To enable both transmission and reflection type by movably providing a light emitting window and a photoreceiving window by a flexible photowaveguide line. CONSTITUTION:A light emitting element 3 and a photoreceptor 4 are mounted and bonded on a substrate with leads 1. A housing case movable unit 7 made of light shielding resin supported by a housing case board 5 made of light shielding resin and a support is coated. Condensing lenses 10 are provided in the light emitting window 8 and the photoreceiving window 9 of the unit 7, and a photowaveguide line 11 having flexibility is contained. With the thus construction, since the windows 8, 9 can be freely altered in the directions, they can be used as light transmission and reflection type sensors. Further, they can countermeasure the variations in the distance between the reflector and the sensor and the inclination.</p> |
