Abstract
PURPOSE: To increase not only the velocity but the efficiency of the character reading, by detecting the rectangular window frame through which the character information on the reading subject is read and then deciding the line direction of the character in accordance with the result of the above detection.
CONSTITUTION: The postal matter P is conveyed in the a-direction to receive the read scanning at the position of the reading part 1, and this output is supplied to the deciding part 20. At the part 20, the horizontal and vertical projections A and B are obtained for the window frame W of the matter P with a comparison given between the lengths of A and B. And in case B is longer than A, it is decided that the matter P is parallel to the longer direction of the frame W. On the other hand, a read scanning is given to the matter P arrived at the reading part 11, and this output is supplied to the recognizing part 30. At the part 30, the read character, i.e., the postal zone number N in this instance, is recognized by the outputs of the parts 20 and 11. Accordingly, the frame W is detected with its shape decided, and thus the describing direction of the number N can be decided. As a result, not only the reading velocity but the reading efficiency can be increased for the character.
