As shown in FIG. 5, a response key 20, a response content setting switch 21, a response signal generation unit 22, a response signal transmission unit 23, and a response signal transmission antenna 24 are added to the receiver 2 according to claim 1. The response content setting switch 21 is a switch for not only replying surely when receiving a response but also for replying a response content such as a simple affirmative response, negative response, or immediate return or no immediate return. is there. When the response setting switch 21 is set and the response key 20 is pressed, the reason for calling and the requirement are read from the function display section 14, and the response signal generating section 22 displays a personal identification similar to the transmission data 17 as shown in FIG. The response data 26 including the code 15 and the response content code 25 is generated. On the other hand, as shown in FIG. 7, the transmitter 1 includes a response signal receiving antenna 27, a response signal receiving / demodulating unit 28, a response data decoding unit 29, a personal identification code match detecting unit 30, a response notifying unit 31, and a response content display unit 32. Add. When the response signal receiving antenna 27 receives the response signal, the response signal receiving / demodulating unit 28 demodulates and outputs the response data 26 shown in FIG. The personal identification code 15 transmitted at the time of calling is recorded in the transmission data encoding unit 5 and input to the response data decoding unit 29. Similar to the operation of the receiver, it is compared with the personal identification code 15, and if they match, it is understood that there is a response from the response notifying section 31. Further, the response content is found from the response content display section 32.

The present invention according to claim 3 will be described. As shown in FIG. 8, the transmitter 1 according to claim 1 generates all-person call key portion 18 to be pressed when calling all persons, and individual identification codes 15 of all persons are sequentially generated at fixed time intervals only when the key 18 is pushed down. , A personal identification code sequential generation unit 19 which is sequentially generated from the beginning is added. When calling all members of a specific group, it is possible to call all members of the specific group in the same manner by setting the group key 33. On the receiver side, the same receiver is used without changing the receiver described in claim 1. With such a configuration, it is possible to receive the calling signal at a constant cycle while the key 18 is being pressed.

The present invention according to claim 4 will be described. As shown in FIG. 9, a transmitter code generation unit 34, a priority determination unit 35, and a transmission data selection unit 36 are added to each transmitter. An active TX signal 37 indicating whether or not the call key 3 of its own transmitter and another transmitter is pressed is connected to the priority determination unit 35. The transmission data selection unit 36 is connected with transmission data 38 from its own transmitter and other transmitters. When the call key 3 is pressed, the transmission data 17 in which the transmitter code 45 is added to the function code 16 as shown in FIG. 11 is created and transmitted. Details of the priority determination unit 35 and the transmission data selection unit 36 are shown in FIG. The active TX signal 37 of each transmitter will be described as TX1, TX2, TX3, ..., TXk, and the transmission data 38 will be described as DA1, DA2, DA3 ,. . The active TX signal 37 is a negative logic signal, and when the call button 3 of an arbitrary transmitter is pressed, the priority transmitter determination unit 49 generates an address signal of the transmission data selection unit 36. The transmission data selection unit 36 selects and outputs the transmission data 38 corresponding to the designated address. If the call button 3 of any transmitter is pressed immediately after the call button 3 of any transmitter is pressed, the OR circuit 46, which prevents the transmission data 38 of the previously pressed transmitter from being changed, The inverter 47 and the timer circuit 48 lock the address signal output from the priority transmitter determination unit 49 for a certain period so as not to change it. On the other hand, on the receiver side, a transmitter code storage section 44 is added as shown in FIG. The transmitter code storage section 44 is a storage section for recording the transmitter code 45 included in the ringing signal transmitted from the transmitter, and when the response key 20 is pressed, as shown in FIG. The response data 26 added with the received transmitter code 45 is created and transmitted. Since the transmitter code 45 is included in the response signal, it is possible to configure so that the transmitters other than the called transmitter do not react even when receiving the response signal.

[Effect of the invention]

 As described above in detail, according to claim 1 of the present invention, the called party can instantly confirm the reason for calling and the requirement on the spot. This is a very useful function without the need to check the case. According to claim 2 of the present invention, the called party can reply to the calling party without delay, and it is not necessary to wait for the calling party to make a confirmation call, and the message is correctly transmitted. Since it is uncertain whether or not it is possible to save the trouble of calling again. The pager system or the pager system on the premises, which has been practically used in the past, does not have a response function, so the transmitter could not recognize whether or not the called person received the message reliably. According to the present invention, when there is no response, it is sufficient to call again after a certain period of time, or to call another person, and the work efficiency can be greatly improved. According to claim 3 of the present invention, it is very effective in the case where all the people are desired to be gathered at one place at the same time for the purpose of gathering everyone. According to claim 4 of the present invention, in the case of a store having a large sales floor area or a store spread over a plurality of floors, by appropriately arranging a plurality of transmitters, the communication range can be expanded even if the transmission power is weak. It is possible to call all employees from any place where the transmitter is installed.
