AbstractBar symbols having different bar width for representing information are grouped and recorded on a surface of an object. A light-responsive sensor is swept automatically to repetitively scan the density of the surface-reflected light along the direction in which thegrouped bar symbols are arranged, while the object is moved orthogonally thereto. Electrical signals indicative of the bar width derived from the sensor are processed thereafter for the read-in of the coded data.
