Abstract
A measuring head for detecting the location of an object such as a moving sheet of paper is disclosed. An elongated sensor having multiple light-sensitive elements is located perpendicular to the path of the object. A source of light is directed at the sensor, and those light-sensitive elements which are not in the shadow of the object produce a high output, while those in the shadow produce a low output. Circuit means are provided to provide a count of the elements and to store the count corresponding to the transition between the high and low values. This stored count, which represents the location of the object, is then displayed.
