At the same time, control data for driving the buzzer B of each display operation device 3 to be transmitted is transmitted to the display operation device 3 having the name display section 4 to make the buzzer B sound to inform that it is calling. Here, the person or the agent who knows that this ringing and the call is being made by blinking operates the response switch SWb of the nearby display operation device 3 and the operation section 5 corresponding to the name display section 4 being blinked. . That is, when the operation data of the response switch SWa is received, the operation data of the operation unit 5 of the display operation device 3 that is subsequently transmitted is accepted, and the controller 1 receives the operation data of the display operation device 3 having the name display unit 4 by this reception. Since the control data for returning the blinking operation of the name display 4 to the original display operation and the control data for stopping the ringing operation of the buzzer B are transmitted to 3, the state of each display operation device 3 is returned to the original state. is there. By this return, it can be seen that the calling person has confirmed the calling. Here, since the ringing operation of the buzzer B is noisy in the display operation device 3 or the like located in a place unrelated to the calling person, it may be desired to cancel this ringing. In that case, it suffices to push the operation stop switch SWc. In this case, the controller 1 is interrupted by an interrupt.
To the display operation unit 3, operation data for instructing to stop the ringing of the buzzer B is returned, and the controller 1 receiving this operation data transmits the control data for stopping the ringing of the buzzer B to the display operation unit 3. Stop buzzer B ringing. In this case, the blinking operation of the name display section 4 is continued.

If you want to cancel the call, cancel switch S
It is sufficient to operate Wd. In this case, the response switch SWb
The same operation as when is operated is performed, the blinking operation of the name display portion 4 is restored, and the ringing of the buzzer B is stopped.
