ABSTRACT:
A handwritten letter recognition system comprises a reading unit and a recognition unit which are connected to a local area network. In the reading unit, a handwritten letter is read by a reading section to change the read handwritten letter into handwritten letter information, and the information is compressed by a compressing/expanding section and transmitted to the recognition unit via an interface through a transmission path. In the recognition unit, the transmitted information is expanded by a compressing/expanding section and recognized by a recognition section, and the recognition result is compressed by a compressing/expanding section in response to a request for transmission sent from one of terminal units provided on the local area network including the reading unit and sent through the transmission path to the terminal unit which sent the transmission request.
