Beschreibung
Zusammenfassung:	A distance measuring sensor includes an LED emitting light, a projection lens receiving the light from the LED to direct the light to illuminate an object, a light receiving lens collecting light reflected by the object, and a PSD receiving at a location light collected by the light receiving lens to output a signal corresponding to the location. The light receiving lens and the PSD are configured to have an adjustable distance therebetween, as seen along an optical axis from the light receiving lens to the PSD. A distance measuring device and electronics equipped therewith can thus be obtained that can rapidly provide information on a distance of an object over a wide range and be configured of a reduced number of components.
