Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call signal transmission device for causing a calling device to output a calling alert when an incoming call signal is input to a portable mobile communication device such as a mobile phone or a pager from the outside. .

[0002]

2. Description of the Related Art A portable mobile communication device such as a mobile phone or a pager has a built-in call alarm device for informing a user that a radio signal has arrived. The call alert device is configured to issue a call alert such as sounding an alarm or vibration of a vibrator when a wireless signal is received by a portable mobile communication device. Portable mobile communication devices such as mobile phones and pagers are usually formed in a small size so that the user can easily carry them when moving. However, despite its small size, it is not as small as an accessory, such as a tie pin or earring. For this reason, it is unexpected that the user can easily recognize that the incoming radio signal has arrived, such as carrying a portable mobile communication device in his hand or putting it in his clothes pocket. It's annoying.
In particular, in the summer season when there are many cases in which a jacket or the like is taken off, or in the case of women who are concerned about their style, they are often carried around in a bag such as a bag.

A user may carry a portable mobile communication device even when he is in a place where many people are mixed, such as in a train. However, in a crowded place, many people in the surroundings also own a portable mobile communication device in units of several people. For this reason, the alarm of another person's mobile communication device often sounds at a fairly close position.

[0004]

[Problems to be Solved by the Invention] Even when a portable mobile communication device receives a radio signal and the call alarm device is activated, the owner is
There is a problem that you cannot communicate without noticing that. In addition, baggage items such as bags are often placed at a position away from the body, but if the owner puts the mobile communication device in the bag or the like, the problem that the call alert is not noticed further occurs.

Further, when a portable mobile communication device owned by oneself is put in a bag or the like and a ringing alarm sound is produced in the surroundings, the mobile communication device owned by oneself emits a ringing alarm sound. I do not know whether it is calling or the mobile communication device owned by another person is making a ringing alert sound, and when I can not get it, I try to take out my own mobile communication device from the bag etc. There are quite a few things that do not.

In view of the above problems, the present invention allows the user to recognize the incoming of a wireless signal to the portable mobile communication device by storing the portable mobile communication device in the bag. An object of the present invention is to provide an incoming signal transmission device for surely recognizing an incoming wireless signal even in a difficult state. Further, the present invention, even in a crowded place,
An object of the present invention is to provide an incoming signal transmission device that enables a user to recognize whether or not a wireless signal is input to a portable mobile communication device owned by the user.

[0007]

In view of the above-mentioned problems, the invention according to claim 1 has a fixing portion fixed to a portable receiver main body for receiving a wireless signal, and a wireless signal to the portable receiver main body. A receiving relay device having a receiving unit for inputting an incoming signal generated from the portable receiving device main body when an incoming call is received, and a transmitting unit for transmitting a calling radio signal based on the receiving unit inputting the incoming signal.

Therefore, even in a situation where the portable receiving device body is located away from the owner's hand,
When the wireless signal arrives at the main body of the portable receiving device, the receiving relay device generates a calling wireless signal, and the calling device outputs a calling signal (alarm alarm) based on the calling wireless signal. Therefore, even if the portable receiving device itself is in a state where it is difficult to recognize the incoming of the wireless signal, if the user keeps the calling device at hand, the user can surely recognize the calling signal (alarm alarm) from the calling device. It will be possible.

According to the invention of claim 2, in addition to the invention of claim 1, since the calling device is provided at a position distant from the main body of the portable receiving device, for example, a tie with which the user wears the calling device. If it is provided on a decorative article such as a pin, it can be easily carried and can be easily noticed when a wireless signal is received by the portable receiving device.

Further, in the invention described in claim 3, in addition to the invention described in claim 1 or 2, since the receiving portion is provided with a signal processing means for amplifying and rectifying and smoothing the incoming signal, the receiving portion The incoming signal from the main body of the portable receiver can be converted into a better signal for reliable signal processing.

Further, the invention according to claim 4 is, in addition to the invention according to claim 1 or 2, provided with power supply means for supplying power to the transmitting portion only when the incoming signal satisfies a predetermined value. . In other words, since the power is configured to be supplied to the transmitter only by detecting the incoming signal generated from the portable receiver main body, the transmitter is normally not supplied with power. The power consumption of the reception relay device can be suppressed.

Furthermore, the invention of claim 5 is, in addition to the invention of claim 1, 2, or 3, wherein the incoming signal is composed of a voice signal from a sounding body, and the voice signal is received by the receiving section. Since the sound collecting microphone is provided, it is possible to receive an incoming signal generated from the portable receiver main body with a simple configuration.

Further, the incoming signal of the portable receiving device may be constituted by the vibration of the vibrating body. However, the invention of claim 6 is in addition to the invention of claim 1, 2 or 3,
The incoming signal is composed of the vibration signal from the vibrating body, and the acceleration sensor for detecting the vibration signal is provided in the receiving unit, so that the portable receiving device body can generate the incoming signal without sounding the sounding body, The accelerometer can receive incoming signals.

Further, in the invention described in claim 7, in addition to the invention described in claim 4, the receiving section generates the output signal only when the generation time of the incoming signal is longer than a preset set time, A timer circuit for activating the power supply means is provided. That is, when an incoming signal is input to the timer circuit, the timer circuit activates the power supply means, but when a signal with a short generation time such as noise generated around the incoming signal is input to the timer circuit, The circuit does not activate the power supply means. With this configuration, it is possible to prevent the power supply unit from being activated due to the influence of noise.

In addition to the invention according to claim 1 or 2, the invention according to claim 8 is characterized in that the transmitting section has a specific code set in advance when a radio signal arrives at the main body of the portable receiving device.

The code signal is transmitted to the calling device as a calling radio signal. Therefore, the calling radio signal is
Since it is composed of a code signal having a preset specific code, it is possible to more reliably prevent malfunction of the calling device due to noise and an incoming signal from another person's portable mobile communication device. That is, even if there is noise around the sound pressure level and voice generation time that satisfies a predetermined value (level), this noise must match the calling radio signal having a preset code. Since there is nothing, the transmitter is not activated. Further, even if the incoming call signal transmitting apparatus of the present invention becomes widespread in the future, the calling apparatus of the incoming call signal transmitting apparatus owned by itself will generate the calling signal only by the calling radio signal having a specific code. .

Further, in the invention described in claim 9, in addition to the invention described in claim 8, the code signal generating circuit is constituted by an M sequence generator for generating a specific code, and the M sequence generator thereof is provided.

BEST MODE FOR CARRYING OUT THE INVENTION An incoming signal transmission device according to a first embodiment of the present invention and a transmission system using the device will be described in detail with reference to FIGS. 1 to 7. Figure 1
An incoming signal transmission device according to any one of the above embodiments, and a transmission system using the device, including a mobile phone main body 1 serving as a mobile reception device main body, a thin plate-like reception relay device 2, and a decorative article such as a tie pin. And a calling device 3 incorporated therein. It should be noted that this incoming signal transmission device is equivalent to the reception relay device 2
And a calling device 3, and the reception relay device 2 is fixed to the mobile phone body 1 by a fixing portion 2a.
It is adhesively fixed to the outer surface of the mobile phone body 1 via (see FIG. 7).

A receiving antenna 5 for receiving a radio signal 4 generated from a radio base station is provided on a part of the outer surface of the mobile phone body 1 so as to project therefrom. The radio signal 4 received by the receiving antenna 5 is appropriately modulated and amplified by a signal modulation circuit (not shown) built in the mobile phone body 1. As described above, the sound producing speaker 6 as a sound producing body produces a sound signal by producing sound based on the modulated and amplified radio signal 4. The pronunciation speaker 6 is fixed in the mobile phone body 1 and communicates with the outside by a plurality of cutout holes 7 provided in the mobile phone body 1. Therefore, when the wireless signal 4 arrives at the mobile phone body 1, a sound of the sound producing speaker 6, that is, a sound signal is generated toward the outside. This sound (sound signal) serves as a call warning sound (alert sound) as a call signal to the user who owns the mobile phone body 1. The ringing alarm sound generated from the mobile phone body 1 also serves as an incoming signal 8 generated toward the reception relay device 2.

The reception relay device 2 is fixed in the vicinity of the cutout hole 7 on the outer surface of the mobile phone body 1 thus constructed. This reception relay device 2 is formed in a thin plate shape, and one surface thereof is a fixing portion 2a to which an adhesive is applied. The fixing portion 2a is fixed to the mobile phone body 1 by adhesion. Then, the reception relay device 2 receives the incoming signal 8 as shown in FIG. 2, the transmitting unit 10 for transmitting the calling radio signal 23 to the calling device 3, and the transmitting unit 1
It is mainly composed of a power supply circuit section 11 which is a means for supplying power to 0, and a battery 12.

The reception unit 9 of the reception relay device 2 has a battery 12
Power is always supplied from. Therefore, the reception relay device 2 is ready to input the incoming signal 8 from the mobile phone body 1. The receiving unit 9 includes a sound guide tube 13 (see FIGS. 1 and 7) for collecting the ringing alert sound from the mobile phone body 1, that is, the incoming signal 8, a sound collecting microphone 14, and a printed circuit board. It is mainly formed of the formed incoming signal reception circuit section 15. The sound guiding tube 13 is provided so as to project further outward than the end of the thin plate-like reception relay device 2, and the tip of the sound guiding tube 13 facilitates collection of the incoming signal 8 from the sound producing speaker 6 to a mobile phone. It is formed so as to extend to a position facing the cutout hole 7 (see FIG. 1) formed in the main body 1. The incoming signal 8 thus collected is received by the sound collecting microphone 14 and is electrically processed and input to the incoming signal receiving circuit unit 15. The input signal of the incoming call signal 8 is subjected to the signal processing described later, and the reception relay device 2 detects that the incoming call signal 8 is generated from the mobile phone main body 1.

That is, the incoming signal 8 is input to the incoming signal receiving circuit section 15 and the incoming signal receiving circuit section 1 is received.
The signal processing means provided in 5 appropriately performs rectifying and smoothing processing. The incoming signal receiving circuit unit 15 includes an incoming signal amplifying circuit 16 for amplifying the incoming signal 8 from the mobile phone body 1.
And a rectifying / smoothing circuit 17 for rectifying and smoothing the output waveform of the incoming signal 8 amplified by the incoming signal amplifying circuit 16, and a timer circuit 18. The timer circuit 18 is connected to the rectifying / smoothing circuit 17 so that the incoming signal 8 appropriately processed by the signal processing means is input. Then, the timer circuit 18 receives the incoming signal signal from the rectifying / smoothing circuit 17 only when the incoming signal 8 satisfies a predetermined sound pressure level and the state is generated longer than a predetermined time t1. A timer signal 19 as an output signal of 15 is generated for the power supply circuit unit 11.

Specifically, as shown in FIG. 3, a microphone input signal 20 from the sound collecting microphone 14 and a smoothing output 21 from the rectifying / smoothing circuit 17 correspond to the incoming signal 8 emitted from the sound producing speaker 6. Is output. For example, when the incoming signal 8 from the sound producing speaker 6 is continuously output for a predetermined time t1 or longer, the microphone input signal 20 is also continuously output for a predetermined fixed time t1 or longer. At this time, that is, when the microphone input signal 20 is continuously output for t1 time, that is, when the smoothed output 21 is continuously output for t2 time or more, the timer signal 19 is output from the timer circuit 18. Become. The rise of the timer signal 19 is detected, and the power supply circuit unit 11 is activated. Then, as described later, the calling radio signal 23 is transmitted from the transmitting unit 10 to the calling device 3.

If the incoming signal 8 generated from the sound producing speaker 6 is not continuously output for a predetermined fixed time t1 or more and the output is stopped midway, naturally the microphone input signal 20 and the smoothed output 21 are also output. The output will be stopped midway. In this case, the timer signal 19 is not output from the timer circuit 18, so the power supply circuit unit 11 is not activated. The fixed time t1 is a time set for distinguishing the incoming signal 8 received by the mobile phone body 1 from the simple noise generated in the vicinity of the receiving unit 9 of the reception relay device 2, and has an arbitrary length. It can be operated in various ways,
Since normal noise has a large length within about 300 msec (millisecond), it is preferable to set the predetermined constant time t1 from 300 msec or more to about several seconds.

On the other hand, the power supply circuit section 11 includes a battery 12
Power is always supplied from. Then, the power supply circuit unit 11 uses the timer signal 1 from the timer circuit 18.
9 is input, and when the rising of the input is detected, the power of the battery 12 is supplied to the transmission unit 10,
Together with the battery 12, it serves as a power supply means for the transmitter 10.

Further, as shown in FIG.
It is composed of a transmission circuit section 22 and a transmission antenna 24 which serves as transmission means for transmitting the calling radio signal 23 generated from the transmission circuit section 22 to the calling device 3. The transmission circuit unit 22 includes a code signal generation circuit 25,
It mainly includes a code signal modulation circuit 26 and a code signal amplification circuit 27.

Further, the code signal generating circuit 25 has an ID storage circuit 2 for generating a special code such as an ID code.
8 are connected. The code signal generation circuit 25 in this embodiment is composed of an M sequence generator. This M-sequence generator is for generating a specific code which is often used for word synchronization called M-sequence or PN code. M in this embodiment
As shown in FIG. 4, the sequence generator includes three flip-flops 29, 30, 31 connected in cascade, three EX-OR means 32, 33, 34, and flip-flops 29, 30 ,.
Four shift registers R whose output state changes according to the arrangement position of the flip-flop in 31 which is turned on
1, R2, R3, R4.

Then, switches 35, 36, 37 which are turned on and off by pattern cutting or the like are added to the M-sequence generator.
Is connected to the decoder 38. Here, the decoder 38 functions as an ID storage circuit. Then, for example, when the switch 37 is cut and the input signal to the flip-flop 31 is set to the high state, that is, "1", the EX-OR means 34 operates. As a result, the output P2 from between the shift register R3 and the shift register R4 and the output P1 from the shift register R4 are input to the EX-OR means 34, and the output P is input to the shift register R1. . A specific PN code can be obtained by taking the output from any one of the shift registers R1 to R4 configured as described above. In addition,
The EX-OR means 32, 33, 34 perform input / output as shown in FIG. 4 (B). That is, when the input P1 is "1" and the input P2 is "1", the output P is "0".
When the inputs P1 and P2 are "0" and "1" and "1" and "0", respectively, the output P is "1" and the inputs P1 and P2 are both "0".
When it is "0", the output P becomes "0". The output thus retrieved is shown in FIG. As shown in FIG. 5, a random code consisting of 15 bits can be obtained from any of the shift registers R1 to R4. Then, after one cycle of outputting 15 bits is completed, a signal of 15 bits is obtained in the same arrangement order in the next cycle.

This M-sequence generator is operated by an EX-OR.
The position of the means 32, 33, 34 uniquely determines the order of the random numerical values. That is, what turns on the flip-flop 31 between the shift register R3 and the shift register R4 and operates the EX-OR means 34 is represented by PN (4,3), and its random function is represented by f (3). And On the other hand, when the flip-flop 29 between the shift register R1 and the shift register R2 is turned on and the EX-OR means 32 is operated, the output states of the shift registers R1 to R4 are as shown in FIG.
The random number differs from that shown in FIG. The structure that turns on the flip-flop 29 can be expressed as PN (4,1) in the above expression form, and its random function can be expressed as f (1). In this way, the M-sequence generator can generate a random function f (i) that differs depending on the arrangement position of the operating EX-OR means 32, 33, 34. It should be noted that PN (4,2) cannot generate a random numerical value that makes one cycle with 15 units,
It is a random numerical value composed of a number with one cycle being small.
Also, if the number of shift registers is 5, one cycle is 3
A signal consisting of one bit can be generated. By arranging more shift registers in this way, it is possible to obtain a signal composed of a larger number of bits.

When the decoder 38 inputs a 3-bit binary code instead of the switches 35, 36, 37 for pattern cutting or the like, it sets the output of the number corresponding to the input code among the eight outputs to 1, EX-OR of the output destination
It may be a circuit for turning on one of the means 32, 33, 34. The longest sequence code (PN code) pattern output in this way can be used as an ID code. That is, a special code such as an ID code can be obtained by generating the code pattern as it is from the code signal generating circuit 25. Then, this ID code is the EX-OR means 3
It depends on the operating positions of 2, 33, and 34.

That is, this I
A specific signal pattern is set by the D memory circuit 28. In this state, the code signal generating circuit 25 generates a signal which is a source of the calling radio signal 23. Note that in this embodiment, the generation of the specific signal pattern is performed by pattern cutting in which a part of the switches 35, 36, 37 connected to the decoder 38 serving as the ID storage circuit 28 is cut on the printed circuit board as described above. This is done by cutting by a method called. This code signal generation circuit 25
The signal generated in 1 is output to the code signal modulation circuit 26. The code signal modulation circuit 26 includes an oscillator circuit 39.
And is supplied with a high frequency which is the basis of modulation from the oscillation circuit 39.

The code signal input to the code signal modulation circuit 26 is modulated by the code signal modulation circuit 26 and output to the code signal amplification circuit 27. Further, the code signal forming this specific signal pattern is amplified by the code signal amplifier circuit 27 and transmitted from the transmitting antenna 24 to the calling device 3 as the calling radio signal 23. The calling radio signal 23 at this time is continuously transmitted to the calling device 3 while the timer signal 19 is being output. The output time of the timer signal 19 is set in consideration of the conditions described later.

The transmission time of the calling radio signal 23 is, for example, four codes of 64 bits when the ID code portion is set as a set of four codes having 64 bits and is transmitted at a speed of 3 kbps (kilobit per second). Minutes,
That is, it takes about 0.1 second (100 msec) only for the 256-bit ID code part. When transmitting such an ID code, the transmission time of the signal of the preamble portion for causing the calling device 3 to confirm that it is the calling radio signal 23 is about 200 msec, and the transmission of the calling radio signal 23 is terminated. Since it takes about 50 msec for the signal portion to be transmitted, the transmission time for one set of the calling radio signal 23 is 350 msec in total.
It will be about. Then, in the present embodiment, the transmission of one set of the call radio signal 23 is set to be repeated about three times. By transmitting three times in this way, even if the calling device 3 is in a state where it is difficult to receive a radio wave, the calling device 3 can reliably receive the signal of the preamble part at least once. When the calling device 3 receives the signal of the preamble part, the calling device 3
Will receive the signal of the code ID code portion consisting of four 64-bit codes. In this manner, the calling radio signal 23 including one set of four 64-bit codes is transmitted to the calling device 3, whereby the calling device 3 receives the code 4 of the ID code portion of the calling radio signal 23. At least one of the pieces can be surely recognized.

The transmission time is a 64-bit ID.
Is a minimum time required for transmitting at 3 kbps (kilobit per second), and it can be set to transmit during the time when the timer circuit 18 is operating, and other times can be freely set. Also, the transmission speed is 3
Instead of kbps (kilobits per second), if you set it to another speed or set the number of bits of the ID code to another value,
This minimum time will also be different.

Call radio signal 2 thus transmitted
When 3 is received by the calling device 3, the calling radio signal 23 is amplified by a signal amplification circuit (not shown) built in the calling device 3. And call radio signal 23
Outputs a calling signal such as an alarm sound to the outside through the output means in the amplified state. The calling device 3 is of a very small size and is formed so that it can be attached to a decorative item such as a tie pin or an earring.

A specific shape of the reception relay device 2 of the incoming signal transmission device thus configured will be described with reference to FIG. The reception relay device 2 is formed in a thin plate shape so as to be adhesively fixed to the flat surface portion of the mobile phone body 1. In FIG. 7, the reception relay device 2 has a thin plate-shaped transmission antenna 24 formed on the upper surface and a fixing portion 2a for fixing the mobile phone 1 on the lower surface. An electric circuit portion 40 is adhered and fixed to a part of the surface portion of the transmitting antenna 24.
The sound guide tube 13 is formed so as to protrude toward the outside of 0. The transmitting antenna 24 is formed of a conductive copper foil and has its surface coated with a plastic material so that any portion can be easily cut according to the outer diameter shape of the mobile phone body 1. It has become. As a result, the portion where the transmitting antenna 24 projects outward from the outer diameter portion of the mobile phone body 1, that is, the protruding portion can be cut to save space. Further, the electric circuit section 40 is formed on the printed circuit board, and in FIG. 2, the incoming signal receiving circuit section 15, which is a part of the receiving section 9 already described, the power supply circuit section 11, and the transmitting section. Transmission circuit section 2 which is a part of 10
2 and a battery 12 are incorporated. Further sound guide tube 13
Is connected to the electric circuit portion 40 at one end side,
The other end side extends outward from the outer edge of the reception relay device 2. Furthermore, the other end of the sound guide tube 13 is connected to the mobile phone body 1
It is configured to be cut at a position facing the notch hole 7.

The operation of the incoming signal transmission system using the incoming signal transmitting apparatus according to the embodiment of the present invention thus configured will be described. First, when a radio signal 4 is generated from the radio base station to the mobile phone body 1, the radio signal 4 is received by the receiving antenna 5 of the mobile phone body 1. Then, the radio signal 4 is appropriately modulated and amplified by a signal modulation circuit (not shown) built in the mobile phone body 1. In this way, the sounding speaker 6 fixed in the mobile phone body 1 is sounded appropriately based on the modulated and amplified radio signal 4. The sound of the sound producing speaker 6 becomes a call alert sound and at the same time becomes an incoming signal 8 transmitted to the reception relay device 2 by a voice signal.

The incoming signal 8 is received by the sound collecting microphone 14 through the sound guiding tube 13 into the reception relay device 2, and then electrically processed by the signal processing means including the incoming signal amplifying circuit 16 and the rectifying / smoothing circuit 17. Will be processed. That is, the incoming signal 8 is
The signal is amplified by the incoming signal amplification circuit 16, and then the output waveform is rectified and smoothed by the rectification and smoothing circuit 17 and output. At this time, when the incoming signal 8 generated from the sound producing speaker 6 to the reception relay device 2 is continuously output for a predetermined fixed time t1 or longer, the microphone input signal 20 generated from the sound collecting microphone 14 is fixed. The time t1 or more is output, and as a result, the smoothing output 21 generated from the rectifying / smoothing circuit 17 is also continuously output for a predetermined time t2 or more. When the smoothed output 21 is continuously output for t2 or more, the timer signal 19 as an output signal is output from the timer circuit 18. In this way, when the timer signal 19 is generated from the timer circuit 18,
The rise of the timer signal 19 is detected, the power supply circuit unit 11 is activated, and power is supplied to the transmission unit 10.

As described above, when the power supply circuit unit 11 is activated, the power supply circuit unit 11 receives power from the transmission unit 10. And this transmitter 10
The code signal generating circuit 25 generates a code signal having a specific signal pattern. This code signal generation circuit 2
The code signal generated by the M-sequence generator of 5 is modulated by the code signal modulation circuit 26, and then the code signal amplification circuit 27.
Amplified by The code signal thus modulated and amplified is transmitted as a calling radio signal 23 from the thin plate-shaped transmitting antenna 24 toward the calling device 3.

When the calling radio signal 23 having the specific signal pattern is received by the calling device 3, the calling device 3 determines whether or not the calling radio signal 23 has a desired code. . At this time, the calling device 3 stores in advance the same code as the code signal having the specific code generated by the M-sequence generator of the code signal generating circuit 25, and compares it with the received call radio signal 23. . When the code stored in advance and the code of the received call radio signal 23 match a predetermined value, for example, 70% or more, an alarm sound as a call signal is output. At this time, the reason why the ringing signal is set to be output when the signs of both are equal to or more than 70% is due to the following problem. That is, if this ratio is made too low, the recognizability of the code becomes uncertain. On the other hand, if this ratio is increased too much, when noise is generated around the receiving unit 9, it is determined that the input code signal is not the calling radio signal 23, and thus there is a high probability that the calling signal is not generated. turn into. Therefore, it is a balance between the two. This value can be set higher or lower depending on the usage environment.

The calling device 3 is preferably attached to a decorative article worn by the user of the mobile phone body 1, such as a tie pin or earring. When the calling device 3 is incorporated in such a decorative article, the wireless signal 4 is received by the mobile phone main body 1 and, as described above, when the warning sound as the calling signal is output from the calling device 3, the user receives the mobile phone main body. It becomes possible to surely know that the wireless signal 4 has arrived at 1.

By the way, when the incoming signal 8 transmitted from the sound producing speaker 6 to the receiving relay device 2 is output for a time shorter than a predetermined constant time t1 for some reason, or when noise is momentarily generated. When picked up by the sound collecting microphone 14, the microphone input signal 20 generated by the sound collecting microphone 14 and the smoothed output 2 generated by the rectifying and smoothing circuit 17
1 also has a short output of a predetermined fixed time t1 or less than t2, and the timer circuit 19 does not output the timer signal 19. If the timer signal 19 is not output, the power supply circuit unit 11 does not start, so the incoming signal 8 is not transmitted to the transmitting unit 10, and the calling radio signal 23 is transmitted from the transmitting unit 10 to the calling device 3. Not done. Therefore, the calling device 3 does not output an alarm sound as a calling signal.

In the above-described first embodiment, an example in which the reception relay device 2 of the incoming signal transmission device is fixed to the mobile phone main body 1 has been described. However, as shown in FIG. 8, the mobile reception device main body is in a pocket. A bell main body 101 may be used, and the reception repeater 2 may be fixed to the pager main body 101, which will be described as a second embodiment.

A reception antenna 103 for receiving a radio signal 102 generated from a radio base station is provided on the surface of the pager body 101. The radio signal 102 received by the receiving antenna 103 is appropriately modulated and amplified by a signal modulation circuit (not shown) built in the pager main body 101. Based on the radio signal 102 amplified in this way, the sound producing speaker 104 produces a sound. This pronunciation speaker 1
