Abstract
PURPOSE: To read assuredly the postal zone number described within the window of the postal matter, by detecting the window and then setting the reading region according to the result of detection.
CONSTITUTION: The postal matter P receives the read scanning at the reading part 1, and the reflected light is led to the line array 4 via the image-formation lens 3. The array 4 delivers the signal of logic 1 in accordance with the reflected light from the window W covered with the cellophane, and then delivers the signal of logic O to the weak reflected light of the other areas respectively. In such way, the reading signal is sent to the window detecting part 20 to detect the window W. On the other hand, the reading part 11 contains the deflecting lenses 181W183 to eliminate the surface reflected light from the cellophane of the window W. At the same time, the reading region is set according to the result of the window detection. Accordingly, the character recognizing part 30 applies the electrical mask to the reading signal supplied from the part 11 and based on the output of the part 20. As a result, the postal zone number within the region of the window W can be recognized assuredly for the postal matter P.
