Since it is configured to perform wireless communication with the wireless base stations 37 and 38 connected to the terminal 39, the POS terminal 32 and the display / input device 34 are used to change the layout of the seat area or the layout of the kitchen. In addition, it is possible to easily move the printing device 35, and it is not necessary to perform an operation such as changing wiring, and therefore, it is possible to easily change the layout at low cost and in a short time.

  Moreover, since multiplex and bidirectional radio is used, such as time division duplex having a plurality of full-duplex channels described in this embodiment, for example, the system control device 36 Since the print data can be transmitted to the printing device 35 to which the wireless terminal 43 is connected by wire at the same time as receiving the order, the transmission waiting time is short, the collision of radio waves can be reduced, and the business can be performed efficiently. In addition, it is possible to easily increase the number of wireless portable terminals and wireless terminals to be used.

  Further, since the communication protocol described in the RCR-STD 28 is circuit switching, for example, before transmitting order information from the wireless terminal 41 to the wireless base station 37, first, the wireless terminal 41 changes the telephone number of the wireless base station 37. It is necessary to set and transmit, and establish a wireless connection between the wireless terminal 41 and the wireless base station 37. Therefore, if control for establishing a wireless connection is performed before transmitting the order information from the wireless terminal 41, a waiting time of several seconds is required.

  On the other hand, in this embodiment, since the wireless terminal 41 and the wireless base station 37 connected to the POS terminal 32 are always in a wireless connection state, information transmission between the POS terminal 32 and the system control device 36 is not possible. When a transmission / reception request occurs, information can be transmitted immediately. That is, wireless communication between the POS terminal 32 and the system control device 36 can be performed quickly.

In this embodiment, the wireless terminal 41 connected to the POS terminal 32 and the wireless base station 37 are always in a wireless connection state. However, the present invention is not limited to this, and the wireless terminal 42 connected to the display / input device 34 is not limited to this. Alternatively, the wireless terminal 43 and the wireless base station 37 connected to the printing device 35 may be always in a wireless connection state.
Furthermore, by allocating a plurality of slots in the time division duplex system to this communication, the transmission speed can be multiplied by the number of the allocated slots, and the wireless communication can be further speeded up.

  In addition, since the wireless portable terminal 33 and the wireless terminals 41, 42, and 43 perform wireless communication with the wireless base station 37 using a full-duplex wireless link, for example, the wireless portable terminal 33 transmits and receives order data wirelessly. At the same time, without affecting this, the clerk having the wireless portable terminal 33 can have an inquiry function of wirelessly receiving information such as empty table information and remaining order information necessary for the clerk. Efficiency can be improved and clerks can provide more detailed services to customers. In addition, it is also possible for each clerk to communicate with each other using the wireless portable terminal in the store, and the business can be quickly performed without spoiling the atmosphere in the store.

  Further, by using the time division duplex method, the radio base station 37 has a plurality of full-duplex channels, so that the radio base station 37 can perform radio communication simultaneously with a plurality of radio portable terminals and radio terminals. Becomes possible. Therefore, even if the number of wireless portable terminals and wireless terminals increases, or the wireless transmission rate of each terminal increases, and the wireless usage rate increases, collision of radio waves and transmission waiting do not occur frequently.
