PROBLEM TO BE SOLVED: To synchronize outputs from a plurality of communication circuits and to reduce the circuit scale by taking synchronization among data transmission means based on a transmission timing signal sent from a transmitter side synchronization means. SOLUTION: A transmitter side timing generating circuit 16 is a transmitter side synchronization means in common to all data transmission sections 10-1-10-n and a transmission timing signal is simultaneously sent to the data transmission sections 10-1-10-n. All the data transmission sections 10-1-10-n are synchronized by providing the common transmitter side timing generating circuit 16 to the data transmission sections 10-1-10-n. Thus, serial data are sent simultaneously to data reception sections 20-1-20-n, then the data reception sections 20-1-20-n take synchronization of outputted parallel data as a result. |
