This wireless call system outputs a wireless signal when the customer operates the wireless transmitter attached to each table, and the wireless receiver receives and demodulates this wireless signal to make it easy for waitress to see it. By displaying the call on the attached display unit, quick service is provided.

An outline of a conventional wireless call system used in a restaurant is shown in FIG. The wireless call system includes a wireless transmitter 1 and a wireless receiver 2. The wireless transmitter 1
Is installed on the table of a restaurant, and when the call button of the transmitter 1 is operated when requesting a service such as when a customer calls a waitress, a wireless signal is transmitted. This wireless signal is a call control signal that includes information on the ID code corresponding to each installed table.

The wireless receiver 2 is provided with an antenna, receives and demodulates the wireless signal, and based on the demodulated signal, displays the requested table number on the display 2a.

The wireless receiver 2 includes a receiving circuit 21 for receiving and demodulating the call control signal from the wireless transmitter 1, a call display processing circuit 22, an ID code registration table 23, a call display processing memory 24, and a plurality of latches. The display device 2a includes a means 2b and a display window 2c.

The ID code registration table 23 has an ID corresponding to each wireless transmitter 1 included in the call control signal.
It is a storage unit that holds the correspondence between the D code and the display data as a table number to be displayed on the display window 2c of the display 2a. The call display processing memory 24 is a storage unit that holds the ID code included in the call control signal in the order of calling.

The call display processing circuit 22 receives an ID contained in the call control signal each time the call control signal is received.
While adding the code to the last column of the call display processing memory 24, when the waitress responds to the customer who called and clears the ID code corresponding to the customer table, the corresponding ID code is displayed. Erase and carry up all other ID codes.

Further, the call display processing circuit 22 sequentially reads the call display processing memory 24, and displays the display data corresponding to each read ID code in the ID code registration table 2.
It is read out from 3 and output to the display 2a. The latch means 2b of the display device 2a is means for holding display data as a table number output from the call display processing circuit 22, and the display window 2c is means for displaying only one table number, and the corresponding latch. The display data stored in the means 2b is displayed.

With such a configuration, the conventional wireless call system can display the table numbers in the display frame 2c of the display 2a in the order in which they are called by the call control signal. Therefore, the waitress can see the display 2c. As a result, it is possible to promptly and fairly serve customers in the order in which they are called.

[0009]

Here, the above-mentioned ID code must be a code unique to each wireless transmitter, but it is set redundantly when the user makes a setting or adds a transmitter. Then, it cannot operate normally. In order to avoid such duplication of ID code,
As the ID code, an ID code unique to all wireless transmitters is set at the time of production or factory shipment. For this reason, the ID code is generally configured as a code having a relatively long bit length. For example, if 19 bits are adopted as the ID code length, it is possible to set 500,000 or more unique ID codes. You can

On the other hand, as described above, the conventional wireless call system is configured to store the ID codes included in the call control signals in the order of reception in the ID code registration table 23. When the code was cleared, all ID codes after that rank were rewritten. For this reason, a large amount of data needs to be rewritten for the rewriting, and the call control processing circuit 22 takes time to rewrite and the processing speed of the entire device decreases, while the call control processing circuit 22 performs high-speed processing. If such a configuration is possible, there is a problem that the price of the system becomes expensive. Also, because of such a problem, it is not easy to add an additional function.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a wireless call system that operates at high speed at low cost. Further, in the conventional wireless call system, the table numbers displayed on the display device 2a can be displayed only in the order in which the call control signals are received, but even within the same store, each table is handled differently. Sometimes you want to.

For example, when it is desired to give priority to each table in the same store to serve customers, to divide each table into groups, or to respond quickly to customers who call many times. There are cases. The present invention has been made in view of the above circumstances, and provides a wireless call system in which the table numbers displayed on the display can be handled differently for each table and which operates at high speed. Also for the purpose.

Further, when the display unit is installed in a restaurant or the like, there is a case where it is desirable to arrange the back surfaces of the two display units so that the display contents can be viewed from both directions. Has a display unit 2a integrally formed with a circuit section including the receiving circuit 21, and unnecessary radio waves called spurious emission are radiated from the back surface of the display unit.

Therefore, when the two wireless receivers 2 are arranged close to each other, the radio wave radiated from one display unit causes the other receiving circuit 21 to malfunction, or the radio wave is hard to reach. On the other hand, preparing a dedicated unit for such a case leads to cost increase. The present invention has been made in view of the above circumstances, and an inexpensive display unit for a wireless call system that solves the problem of mutual interference between the display units when two wireless receivers 2 are arranged close to each other. It is also intended to be provided to.
