A wireless signal having the frequency of the physical channel is generated and transmitted from the antenna 34a.

  Further, the counter device 1 includes a charging unit that charges the wireless receiver 3 when the wireless receiver 3 is attached to the attachment mechanism. This charging means is a contactless charging circuit, and oscillates the oscillation circuit 35 in accordance with a control signal from the CPU 31 to control the field effect transistor 37 on and off. As a result, the power from the commercial power source 4 in FIG. 1 is supplied to the primary coil 38 from the power source 36 that has been stepped down, rectified, smoothed and stored, and the voltage is applied to the secondary coil of the charging circuit 25 of the wireless receiver 3. Induce. FIG. 3 shows only a single primary coil 38, but there are as many primary coils 38 as the number of mounting mechanisms of the counter device 1.

  In such a counter device 1, the CPU 31 stores the ID number of the wireless receiver 3 attached to the mounting mechanism in the storage unit 32 for each contact switch 33. Thus, the CPU 31 determines the contact signal from which contact switch 33 has been input when the wireless receiver 3 is detached from the counter device 1, thereby obtaining the ID number of the removed wireless receiver 3. recognize.

  In addition, when the wireless receiver 3 is detached from the mounting mechanism, the CPU 31 receives the contact signal indicating that from the contact switch 33 of the mounting mechanism, and the count number currently stored in the storage unit 32 A new count number is issued by incrementing by one. The new count number is supplied to the wireless communication unit 34 together with the ID number of the wireless receiver 3 removed from the mounting mechanism and the transmission command for the count number setting signal. The wireless communication unit 34 transmits a count number setting signal including the ID number of the wireless receiver 3 removed from the mounting mechanism and the new count number to the wireless receiver 3. Thus, when the counter device 1 detects a predetermined operation that the wireless receiver 3 is removed from the mounting mechanism and the charging is released, a new count number is assigned to the wireless receiver 3 that has performed the predetermined operation. Can be stored and displayed.

  As shown in FIG. 1, the wireless transmitter 2 is in a counter in the food court, and is operated by a store clerk to perform an operation for calling a store visitor. The wireless transmitter 2 includes a display unit 2a, a number operation unit 2b, and a call operation unit 2c, and further includes an antenna and a radio communication unit (not shown). The wireless transmitter 2 stores the ID number of the wireless receiver 3 to be used, and receives a wireless signal including a new count number and ID number issued by the counter device 1. Thereby, the wireless transmitter 2 stores the correspondence between the ID number and the count number.

  When the store clerk calls the customer by the store clerk, when the count number is input via the number operation unit 2b and the call operation unit 2c is input, the input count number and the A call notification signal including an ID number corresponding to the count number is transmitted. It should be noted that the input content may be displayed on the display unit 2a as necessary when the store clerk inputs the count number. As a result, the call notification signal is received by the wireless receiver 3 having the ID number included in the call notification signal, and is notified that the call is being called by a store clerk. In this description, the case where both the count number and the ID number are included in the call notification signal will be described. However, the wireless transmitter 2 does not include the count number if the ID number is included in the call notification signal. A call notification signal may be transmitted.

  Next, in the wireless call system configured as described above, refer to FIG. 4 for the operation from when the wireless receiver 3 is detached from the counter device 1 until the wireless receiver 3 is attached to the counter device 1 again. To explain. FIG. 4 shows the relationship between the operation on the counter side where the counter device 1 and the wireless transmitter 2 are provided and the operation on the passenger seat side which is the operation of the wireless receiver 3.

  First, in step ST1, the counter device 1 detects whether or not the wireless receiver 3 has been removed from the mounting mechanism, and inputs a contact signal indicating that the wireless receiver 3 has been removed from the contact switch 33 by the CPU 31. If so, the process proceeds to step ST2, and if the wireless receiver 3 is not removed, this determination is repeated every predetermined time.

  The counter device 1 recognizes the ID number of the wireless receiver 3 when the wireless receiver 3 is removed from the mounting mechanism. The process of recognizing the ID number of the removed wireless receiver 3 is, for example, receiving a wireless signal notifying the ID number of the wireless receiver 3 when the wireless receiver 3 is attached to the counter device 1. Thus, the correspondence relationship between the contact switch 33 that outputs the contact signal at the time of mounting and the ID number is acquired, and the wireless receiver 3 removed from the contact signal of the contact switch 33 from which the wireless receiver 3 was removed is obtained. ID number can be recognized. Further, when the wireless receiver 3 is detached from the counter device 1, the wireless receiver 3 receives a wireless signal that notifies the ID number of the wireless receiver 3, thereby acquiring the ID number of the wireless receiver 3. good. Further, in the case of the wireless receiver 3 that transmits and receives a wireless signal only when it is detached from the counter device 1, the wireless signal is broadcast from the counter device 1 to the plurality of wireless receivers 3, and the removed wireless reception is performed. By receiving the ACK from the device 3, the ID number of the removed wireless receiver 3 may be obtained.

  In step ST2, the CPU 31 of the counter device 1 increments the current count number stored in the storage unit 32 to issue a new count number that is incremented by 1 from the most recently issued count number. Update the count number of 32. For example, when the most recently issued count number is “15”, a count number “16” that is incremented by 1 from the “15” is set as a new count number.

  In the next step ST3, the CPU 31 of the counter device 1 counts including the new count number “16” updated in step ST2 and the ID number of the wireless receiver 3 removed from the counter device 1 recognized in step ST1. The number setting signal S1 is transmitted from the wireless communication unit 34. The count number setting signal S1 is also received by the wireless transmitter 2, and the correspondence relationship between the ID number and the count number “16” is stored by the wireless transmitter 2.

  When the CPU 10 of the wireless receiver 3 receives the count number setting signal S1 in step ST11, if the ID number included in the count number setting signal S1 is its own ID number stored in the EEPROM 23, The count number “16” included in the count number setting signal S 1 is extracted and stored in the EEPROM 23. In step ST <b> 11, the CPU 10 causes the display unit 20 to display the count number “16”.

  Thus, when a new count number “16” is issued by the counter device 1 and the count number “16” is displayed by the wireless receiver 3, the store side confirms the count number “16”, The wireless receiver 3 is delivered to the customer. Accordingly, the count number “16” can be associated with the ordered product, and the ordered product can be prepared according to the order of the count number, that is, the order received.

  In the next step ST4, for example, in order to deliver the ordered product to the customer holding the wireless receiver 3 with the count number “16”, the number operation unit 2b of the wireless transmitter 2 is operated on the counter side, and the count number When “16” is input and the call operation unit 2 c is operated, the wireless transmitter 2 acquires an ID number corresponding to the input count number “16”, and the ID number and the count number “16”. A call notification signal S2 including The call notification signal S2 includes the ID number and the count number. However, only the ID number may be used as long as the wireless receiver 3 can perform a call operation in the order of the count number.

  When the CPU 10 of the wireless receiver 3 receives the call notification signal S2 in step ST12, in step ST13, the CPU 10 determines whether or not the ID number included in the call notification signal S2 is its own ID number stored in the EEPROM 23. If it is the self ID number, the process proceeds to step ST14, and if it is not the self ID number, the process returns to step ST12 to wait for reception of the call notification signal S2.

  In step ST14, the CPU 10 of the wireless receiver 3 determines whether or not the count number included in the call notification signal S2 received in step ST12 is the count number “16” stored in the EEPROM 23, and is stored in the EEPROM 23. If the count number is “16”, the process proceeds to step ST15. If the count number is not “16” stored in the EEPROM 23, the process returns to step ST12 to wait for reception of the call notification signal S2. It becomes a state.

  In step ST <b> 15, the CPU 10 of the wireless receiver 3 performs a call operation for notifying that a call has been made from the store by controlling the sound generator 19. As a result, the visitor can carry the wireless receiver 3 and go to the store where he / she ordered and receive the ordered item.

  Thereafter, when the wireless receiver 3 is returned to the mounting mechanism of the counter device 1 and reattached, the counter device 1 detects the contact signal from the contact switch 33 by the CPU 31 in step ST5, and the wireless receiver 3 Is detected, the process proceeds to step ST6, and the count number “16” is reset. In this reset process, the correspondence between the current count number “16” and the ID number of the wireless receiver 3 is deleted.

  At the same time, in step ST16, the wireless receiver 3 is attached to the counter device 1 by the CPU 10 when the charging state detection unit 26 detects that the charging circuit 25 has received power from the counter device 1 and started charging. When this is detected, the process proceeds to step ST17, and the count number “16” stored in the EEPROM 23 is reset to be erased.

  As described above in detail, according to the wireless call system to which the present invention is applied, when the counter device 1 is detached from the wireless receiver 3, the latest count number is incremented and a new count number is issued. A plurality of wireless receivers 3 removed from the apparatus 1 can store consecutive count numbers, and the wireless receivers 3 can be given count numbers in the order in which the wireless receivers 3 are delivered to the customers. For example, it is possible to provide an association between the ordered item, the order of order, and the count number of the wireless receiver 3 in a kitchen in a food court. Thereby, it is possible to avoid mistakes before and after the order order as in the case where the unique number of the wireless receiver 3 is different from the order order.

  Further, according to this wireless call system, since the call notification signal includes the count number and is transmitted from the wireless transmitter 2 to the wireless receiver 3, operation input to the wireless transmitter 2 is performed using the count number. Therefore, it is possible to avoid a malfunction as compared with a case where a customer is called by the ID number of the wireless receiver 3.

  Furthermore, according to this wireless call system, the count number is incremented in conjunction with a predetermined operation of removing the wireless receiver 3 from the state where the wireless receiver 3 is attached to the counter device 1 and being charged. Therefore, the operation for incrementing the count number is simple, and the trouble of forgetting the operation for incrementing the count number like other operations can be avoided.

  Furthermore, according to this wireless call system, when the wireless receiver 3 is attached to the counter device 1 and an operation for starting charging is performed, or the wireless receiver 3 is detached from the counter device 1 to release the charge. When the operation is performed, a number setting signal is transmitted to the wireless receiver 3 and a count number is assigned to the wireless receiver 3, so that it is possible to avoid a transmission error such as being out of the communication range of the counter device 1. .

  The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment.
