Abstract

The present invention provides an information transmitting / receiving system, by which it is possible to receive all information data by putting priority rank to the information when all information data cannot be transmitted at one time due to a limitation in the communication means. The information transmitting / receiving system comprises handwritten information extracting means 405 for dividing the information to a set of a plurality of data, a data transmission setting unit 406 for setting a timing to transmit a plurality of divided data to a plurality of data transmitting units, communication units 402 for transmitting the divided data from an information data transmitting unit 407 via a transmitting / receiving server 416, and a mobile information system 403, which comprises a handwritten / image data receiving unit 410 for receiving the data, a handwritten / image data processing unit 411 for restoring the received data to the initial information, and a handwritten / image data display unit 412.
