Abstract
A mail sorting apparatus includes a video signal conversion section for photoelectrically converting and quantizing characters, codes, and the like on a mail item into a video signal, a blank area detection section for detecting a blank area where characters, codes, and the like are not described on the basis of the video signal output from the video signal conversion section, a printing area designation section for designating a bar code printing area in the blank area detected by the blank area detection section, and a bar code printing section for printing a bar code corresponding to an address of the mail item on the printing area designated by the printing area designation section. Further, the printing area designation section designates the bar code printing area from a blank area obtained by excluding a window area detected by a window position detection section from the blank area detected by the blank area detection section.
