PURPOSE:To compress the code information and to transmit it with high efficiency, by dividing the code information into component elements of said information and obtaining the difference of these component elements to transmit it serially. CONSTITUTION:A character output part 11 supplies the transmission information 12 to a code memory 13, and the memory 13 converts the information 12 into an ASCII code. The code information 14 obtained after conversion is stored at a code buffer 15, and arithmetic circuit 16 designates successively every two adjacent elements out of the information 14 stored in the buffer 15 and supplies them as the adjacent code information 17. The ASCII code of an advance element is defined as ''X1X2H'' out of the adjacent code information 17, and the element ''Y1Y2H'' follows the code ''X1X2H''. The circuit 16 carries out an operation and delivers the arithmetic information 18. A binary coding circuit 19 binary codes the information 18 into a transmission signal 21. |
