Abstract
Line portions of the character pattern in a character recognition device which have a thickness less than a selected standard value are thickened by a thickening circuit to the selected value. The line thickness of the character is then uniformly thinned by a thinning circuit and the thickening process is repeated. A correction circuit may be provided to prevent the continuity of the character from being broken in the thinning circuit.
