Abstract

PURPOSE:To make it possible to transmit and receive various information, by forming the system so that the transmission by both the functions of a standard mode and a high picture quality mode can be executed from the terminal equipment to the center equipment. CONSTITUTION:The picture information which has been read by the picture reading part 11 is accumulated into the main memory 13 after it has been compressed by the data compressing part 12. This compressed data is sent out from the external circuit to the terminal equipment through the communication control and transmission circuit network control part 14. The terminal equipment which has received it decodes the picture information by expanding the data by the data compressing and expanding part 22, records it in the recording part 20, and executes a regular facsimile communication. On the other hand, in case of transmission from the terminal equipment, after executing binary encoding or multilevel encoding of the picture information which has been read by the picture reading part 21, by means of the encoder, and removing the redundancy, it is sent out to the center equipment from the external circuit through the communication control and transmission circuit network control part 24. The center equipment records it in the recording part 10 after the receiving processing.
