ABSTRACT Apparatus for detecting contours and measuring dimensions of an objects employs a plurality of light transmitting means for trans- mitting a scan of an equal plurality of light rays, and also em- ploys an equal plurality of light receiving means, each arranged to receive light from only a complementary one of the light trans- mitting means. The object is moved through the light rays such that the objects prevents the light receiving means from receiving light shining on one side of the contours of the object. Counter means are employed for counting the number of light receiving means which receive light from corresponding light transmitting means. The light transmitting means and light receiving means are disposed in a configuration enabling a more sensitive detection of the contours yet avoiding the risk of "cross-talk" between adjacent light receivers.
