Title:
AUTOMATIC RANGE FINDER
Document Type and Number:
WIPO Patent Application WO/1981/001610
Kind Code:
A1
Abstract:
An automatic range finder for measuring the distance to an object on the basis of the triangulation principle, including a light-emitting diode (16) for projecting the emitted light toward an object whose distance is to be measured, and a plurality of light-receiving elements (8a, 8b, 8c, 8d) being so arranged on a substrate (12) that either one of them can receive the reflected light from the object. The light-emitting diode (16) is electrically connected with planar, electrically conductive frames (20) (22) and is so molded by use of transparent material (26) as to be formed unitarily with the electrically conductive frames. The light-emitting diode (16) thus formed into one unit is mounted on the substrate through the electrically conductive frame.
