ABSTRACT:
In an apparatus for processing embossed characters on an embossed card, a sensing head has sensing wires extending generally parallel with each other in a first direction, the tips of the sensing wires disposed at different positions along a second direction orthogonal to the first direction. The sensing wires are repeatedly actuated toward their tips. Advancement of each sensing wire exceeding a predetermined distance is detected and electrical signals indicating the results of detection are produced. The embossed card is moved relative to the sensing head in a third direction orthogonal to the first and second directions, with the surface of the embossed card held parallel with the second and third directions, and close to the tips of the sensing wires. The sensing wire is repeatedly actuated toward the embossed card so that the tip of each sensing wire hits or does not hit the surface of the embossed card before exceeding the predetermined distance depending on whether or not the sensing wire is confronting an embossment or not.
