Then, the wireless transmission destination ID is acquired (ST51), and the data is wirelessly transmitted to the management wireless slave station (for example, 40A) (ST52). On the contrary, data is wirelessly received from the management wireless slave station (for example, 40A) (Y in ST53).
Then, the acquired wireless transmission source ID is added (ST54), and the data is transmitted to the host device 10 by wire (ST55).

On the other hand, in the management wireless slave station (for example, 40A), when the wireless transmission request is received by wire from the terminal (T / M) 30A (YES in ST60 of FIG. 14), the wireless transmission source ID is obtained (ST61). ) And wirelessly transmits to the wireless base station 20A (ST62). When the data is wirelessly received from the wireless base station 20A (YES in ST63), it is confirmed that the wireless slave station (40A) is in question (Y in ST64).
After S), wire transmission to the terminal device 30A (ST6
5) Do it.

In such a wireless communication system, the wireless base station (2
0A), there is a certain limitation on the radio wave propagation distance that allows stable radio communication, that is, the radio wave stable area AR. Therefore, when installing a large number of terminal devices 30, it is necessary to install a plurality of wireless base stations 20.

For example, as shown in FIG. 12, a plurality of terminal machines (for example, 30A to 30A) arranged in a sales floor area F1.
A radio base station 20A having a radio wave stable area AR1 is provided for each of the management radio slave stations 40A to 40C in C), and similarly, a radio wave stable area AR2 (F) of the radio base station 20B is provided.
2) Management radio slave stations 40D to 40F are provided in the radio base station 20C (20D) to stabilize radio waves AR3 (AR4).

When the data is wirelessly received, the common data is formed so that the common data can be wirelessly transmitted to the unmanaged wireless slave station stored in the unmanaged wireless slave station storage means, and the unmanaged wireless slave station is configured to perform the relay wireless communication. The commodity sales registration data processing device is configured to be capable of wirelessly receiving common data wirelessly transmitted from the relay wireless slave station stored in the slave station storage means.

According to the above invention, when the relay wireless slave station wirelessly receives the common data wirelessly transmitted from the wireless base station without designating the wireless slave station, the relay wireless slave station performs the wired transmission to the terminal device as well as the unmanaged wireless slave station. Wirelessly transmits to the unmanaged wireless slave station stored in the station storage means. When the unmanaged wireless slave station wirelessly receives this common data from the relay wireless slave station stored in the relay wireless slave station storage means, the common data can be transmitted to the unmanaged terminal device by wire.

Therefore, in addition to the same operational effects as in the case of the inventions of claims 1 and 2, common data can be set for the non-management terminal machine as in the case of the management terminal machine. Because it is possible, the usability can be further enhanced.
