FIGS. 7 and 8 show flowcharts when the return call device is used. The operation of the return call device will be described with reference to FIGS. FIG. 7 shows an example of a case where a call is made on the transmitter 10 side. After turning on the power switch 14 on the transmitter 10 side, the call button 13 is pressed (step 10).
1), the signal is sent to the transmitter control circuit 43, and the transmitter control circuit 43 drives the signal transmission circuit 41 to output a calling signal to the receiver 20 by FM radio waves (step 1).
02).

After that, the transmitter control circuit 43 takes a certain waiting time (step 103), and within the waiting time, a calling response signal is transmitted from the receiver 20 by FM radio wave, and the response signal receiving circuit 42 receives it. It is determined whether or not it has been performed (step 104). When the call response signal is sent, the transmitter control circuit 43 blinks the green reception lamp 11 (step 105). If the call response signal has not been sent within the standby time, the red reception impossible lamp 12 blinks (step 106). In any case, the transmitter control circuit 43 blinks the lamp 11 or 12 for a predetermined time, and then ends (step 107).

On the receiver 20 side, when the calling signal is received by the signal receiving circuit 52 (step 111), the receiver control circuit 53 immediately drives the response signal transmitting circuit 51 to send back the calling response signal by FM radio wave ( Step 112). Then, the chime sound is called from the chime sound recording circuit 55, and the reproduction circuit 56 is operated to reproduce the chime sound from the speaker 24 (step 113). Then, the reproduction circuit 56 is operated and the IC is recorded in the storage circuit 54. The audio signal is reproduced (step 114). The reproduction of the chime sound and the audio signal is repeated up to three times, and when the third time ends (step 115), a series of operations is ended (step 116).

FIG. 8 shows an example in which the transmitter 10 performs confirmation. When the confirmation button 14 is pressed on the transmitter 10 side (step 201), the transmitter control circuit 43 recognizes this and drives the signal transmission circuit 41 to output a reception confirmation signal to the receiver 20 by FM radio waves (step 201). 202).

Thereafter, the transmitter control circuit 43 takes a predetermined standby time (step 203), and within the standby time, an acknowledgment signal is transmitted from the receiver 20 by FM radio wave and received by the response signal receiving circuit 42. Is determined (step 204). When the acknowledgment signal is sent, the transmitter control circuit 43 blinks the green reception lamp 11 (step 205). If the acknowledgment signal has not been sent within the standby time, the red reception disabled lamp 12 flashes (step 206). In each case, the predetermined time,
After blinking the lamp 11 or 12, the process is terminated (step 207).

On the receiver 20 side, when the receiver control circuit 53 receives the reception acknowledgment signal by the signal reception circuit 52 (step 211), it immediately drives the response signal transmission circuit 51 to send back the acknowledgment signal by the FM radio wave. (Step 21
2), end (step 213). The power switch 29 of the receiver 20 is normally turned on when the child goes out. However, if the necklace 22 is automatically turned on when the child is put on the neck of the child, forgetting to turn on the power can be prevented.

When a voice signal is recorded by the receiver 20, when the IC recording button 31 is pressed and voice is input from the microphone 28, the content is stored in the storage circuit 54 by the receiver control circuit 53. When it is desired to check the stored contents, when the play button 32 is pressed, the audio signal recorded under the control of the receiver control circuit 53 is output from the speaker 24 by the operation of the play circuit 56. If you want to protect the recorded content, after recording is completed, lock switch 3 for IC recording
0 is turned on.

According to the configuration of the return call apparatus of the present embodiment as described above, 1) a set of a transmitter and a receiver is used to play a receiver corresponding to a specific transmitter. The child can be notified of the "return call" by FM radio wave. 2) The receiver is a pendant type that can be made small and lightweight, and has an IC recording / reproducing function. 3) The receiver can reproduce from the speaker the "return call message" and the "chime" stored in the ROM, which have been IC-recorded in advance by a signal from the transmitter. Reproduction is automatically repeated a plurality of times (three times in the above description).

4) The message content of the IC recording can be protected by a lock switch. 5) Transmitter and receiver are specified IDs by tone signal etc.
Because they recognize each other by numbers, no interference occurs between similar models. 6) Signals used by the transmitter and the receiver are, for example, tone signals, and are transmitted and received as analog or digital signals. In the case of an analog signal, the receiving side recognizes the analog signal as one pattern. In the case of digital signals, the receiving side recognizes them by performing digital / analog conversion.

7) Since the receiver side is all automatic reception and automatic reproduction and automatic stop, the child wearing the receiver does not need to perform special processing or operation only by listening to the message. 8) Since the transmitter has a mechanism capable of determining whether or not the receiver is within a range where the signal can be received, the transmitter can determine whether or not the child has gone far away. 9) Since there is a mechanism on the surface of the receiver to put emergency information and pictures, it is possible to contact even if you get lost. Etc.

The present invention is not limited to the above embodiment, but can be variously modified. For example, a transmitter,
Although the communication between the receivers has been described as being carried by carrying an analog or digital tone signal on the FM radio wave, the present invention is not limited to this, and the signal format can be freely selected. In particular, if the transmission power is within the range of a weak radio wave for the purpose of using the present invention, there is no restriction on the frequency or the communication format, and any communication method may be adopted. It is also possible to provide a plurality of types of contents of the voice signal stored in the IC and to call them separately by a calling signal.

In the above embodiment, the receiver is a pendant type. However, various shapes such as a broach type to be attached to clothes and a waist porch type to be fastened to a belt can be used. Can be selected. In the case of the pendant type, the necklace can be used as an FM radio wave antenna of the receiver. In addition, by incorporating a game function and a watch function into the receiver, it is possible to configure a receiver that the child is willing to carry.

[0030]

As described above, according to the present invention, a child is provided with a pendant-type receiver, and a FM transmitter is transmitted from a home transmitter.
Since a voice signal recorded by IC is reproduced by a signal transmitted by radio wave to encourage the child to return home,
A relatively inexpensive, simple, compact and lightweight device that does not place a lot of burden on the possession of a child, can easily encourage a child who is out of home to return home, and whether a child who is out is in the neighborhood It can be easily confirmed by a response signal to the FM radio wave.
