Further, the coordinate detecting unit such as a tablet forming the input screen 100 always operates in parallel with other functional units so that writing can be always performed. Here, when the character string "today" is entered in the first line of the initial screen shown in FIG. 2 using the pen 3 of FIG. 1, the coordinates are detected by the display-integrated coordinate input unit 1 and detected. When the coordinate information is displayed on the LCD constituting the input screen 100, the handwriting "Kyowa" is displayed as shown in FIG. At this time, when the display-integrated coordinate input unit 1 detects the coordinate information of the handwriting input as described above, character recognition is performed based on the detected coordinate information, and the character recognition result is also displayed on the input screen 100. The character recognition result, the input position information, and the like are transferred to the first information transfer unit 11 shown in FIG. 4, and a data shaping process for transferring to the information storage processing unit 2 is performed here.

The first information transfer unit 11 transfers the data-formed information to the second information transfer unit 21 of the information storage processing unit 2 via the cable 5 according to a predetermined communication protocol. The communication protocol is used for the display-integrated coordinate input unit 1 and the information storage processing unit 2 to identify each other or to increase the reliability of information to be transferred, and is widely used in, for example, a computer network. TCP
A communication protocol such as / IP can be used. The second information transfer unit 21 of the information storage processing unit 2 receives the information transferred from the display-integrated type coordinate input unit 1 according to the communication protocol, analyzes the received information, and then transfers the information to the information processing management unit 22. send. The information processing management unit 22 converts the sent information into a predetermined format and converts the information into the information storage unit 2.
