PURPOSE:To obtain a transmission system which uses a conventional start-stop synchronous type device and further improves transmission efficiency by employing a transmission format which is not restricted by a transmission code. CONSTITUTION:A data part A except STX and ETX is converted on specific basis to obtain a bit pattern different from a communication control code. Namely, information A is inputted and on/off states of top bits are transferred to a 16-bit buffer B at intervals of 14 pieces 8-bit data. Then, this buffer B is added to the top of every 14 pieces of data of the information A to obtain a buffer C. With regard to the whole information A, said operation is repeated. Lastly, tip bits of 8-bit data in the buffer C are all turned on and the STX and ETX are added to obtain a buffer D. This buffer D is sent out as output data to a circuit. |
