れる。The transmission device 11 is a control transmission device for adjusting the time of other transmission devices 12 to 4, and has the configuration shown in FIG. In FIG. 1, the time measured by a timer 20 is supplied to a decoder 21 and a CPU 22. The decoder 21 decodes the time from the timer 20, and when this time reaches a preset time such as 0:000 minutes every day, it generates an interrupt signal IRQ and supplies it to the CPU 22. CPU
22 outputs a time set command when supplied with the interrupt signal IRQ from the decoder 21, and this time set command is sent to the network 10 from the terminal 24 through the transmitting/receiving section 23.
