PURPOSE:To allow plural users to operate a commander simultaneously by sending a command signal in a different timing from plural controllers corresponding to a reference signal from a reference signal generating circuit. CONSTITUTION:A reference signal with a prescribed period from a reference signal generating circuit 13 is sent to terminal equipments 2A-2C via a common bus 3. When a command signal from commanders 24A-24C is sent, the controllers 23A-23C convert the command signal into a compressed command signal and the controllers 23A-23C output the compressed command signal after a delay time specific to respective terminal equipments elapses after the reference signal is received. Thus, even when the commanders 24A-24C are operated simultaneously by plural users, collision of the command signals does not take place through the common bus 3. |
