PURPOSE:To attain a quick data transmission processing by providing an address register to send same transmission command and data in parallel to each transmission line, sending an individual address from the address register at the transmission of terminal address and sending the same content to plural transmission line in parallel. CONSTITUTION:A required line address is designated at first sequentially, a terminal address is set to corresponding address registers 20-1-20-n to set the line adaptor bit of a line register 23. In sending a transmission command while setting sequentially a command word and a data word sequentially to a transmission register 6, they are inputted to signal switches 2-1-2-n via switches 21-1-21-n. An address transmission control section 22 sets an output line synchronously with the transmission period of the terminal address part of the command word and uses the signal to change over the switches 21-2-21-n to the position of the registers 20-1-20-n for the shift and sends the terminal address signal to signal lines 1-1-1-n. Thus, the data of the same text is sent to all the transmission lines at the same time.
