The pen comprises an elongated housing having a light aperture at one end. A plurality of light-emitting diodes is mounted in the housing, and means are provided for focusing the light from such diodes at the light aperture. In use, the pen is held against a coded label and moved therealong. Light from the light-emitting diodes strikes the coded information, so as to produce a light pattern. Lenses in the housing focus the reflected light onto a detector which produces electrical signals in accordance with the light pattern.
