Letter sorting installation for mail items with horizontally and vertically arranged address information

摘要

A postal letter sorting system feeds letters continuously past an optical detector (6). Associated with the main image detecting process is a further detector (8) that identifies a coding block, either horizontally or vertically positioned on the surface of the letter. When in the vertical position, the block information is rotated through ninety degrees and is then superimposed upon the main letter display on a screen. The code-sensing unit has an associated processor to identify the area. ADVANTAGE - Processes mixed horizontal and vertical address information.
