Abstract

PURPOSE:To easily discriminate address information part and make possible the reduction of a read area for the postal matter in which communications are stated on the same surface as the surface where the address information is stated by providing the 1st and 2nd read parts and a character density deciding circuit. CONSTITUTION:When postal matter P is conveyed in an arrow (a) direction and opposes to the 1st read part 1, the surface of the postal matter P is read and scanned by the 1st read part 1, and the output thereof is supplied to a character density deciding circuit 30. Divided regions are then set on the surface of the postal matter P by the circuit 3 and according to the character densities of the divided regions, an address information part is discriminated. On the other hand, when the postal matter P opposes to the 2nd read part 21, said postal matter P is read and scanned by the 2nd read part 21, and the output thereof is supplied to a recognizing part 40. In the recognizing part 40, an electrical mask is applied on the output of the 2nd read part 21 by the output of the circuit 30, by which the address information part on the postal matter P is made a read region. In this way, the recognizing part 40 recognizes the read characters in the address information part region.
