Abstract
Device for detecting a position of an edge includes a row of light-emitting elements forming an angle with the edge, an optoelectric transducer disposed adjacent the light emitter elements for receiving light emitted by the light emitting elements, first means for guiding the edge between the row of light-emitting elements and the optoelectric transducer, second means for pulsatingly energizing the light-emitting elements sequentially, and third means for scanning an output voltage of the optoelectric transducer in synchronism with the pulsating energization of the light-emitting elements.
Claims9
Device for detecting a position of an edge comprising a row of a multiplicity of light-emitting elements forming an angle with the edge, a single optoelectric transducer disposed adjacent said light emitter elements for receiving light emitted by said light emitting elements, first means for guiding the edge between said row of light-emitting elements and said optoelectric transducer, second means for pulsatingly energizing said light-emitting elements sequentially, and third means for scanning an output voltage of said optoelectric transducer in synchronism with the pulsating energization of said light-emitting elements.
