PURPOSE:To report the approximate queuing time to a customer at a window of a bank or the like to improve the service, by providing a display device for queuing time, an operation device for queuing time, and a communication device for sending a calculated queuing time to the display device. CONSTITUTION:A time counting device 16 is used for updating the queuing time in accordance with the elapse of time. Carrier waves of frequencies different from one another are assigned to respective queuing time display equipments 3 for the purpose of designating display equipments 3. When a terminal controller (TC) 1 sends queuing time information to a specific display equipment 3, the TC1 sets the assigned frequency to a frequency variable transmitting part 15 and transmits information with its carrier wave. The display equipment 3 receives only the carrier wave of a frequency set to a receiving part 34. Thus, the TC1 selects only one of plural display equipments 3 to transmit queuing time information. |
