DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an analog cordless telephone, a digital cordless telephone (for example, PHS).
The present invention relates to a telephone (hereinafter, referred to as a “mobile telephone” in the present application) that carries a call-in / out operation through a wireless channel, such as a slave station, a mobile telephone, and the like.

[0002]

2. Description of the Related Art In general, a portable telephone has an antenna at the top, a receiver at an upper front, a transmitter at a lower front, and a receiver at a lower portion of a housing structure that can be gripped by a user. It has an appearance in which an operation unit (keypad or the like) and a display unit (LCD or the like) are provided in the space between the transmitters. Some products have a structure that is folded during non-calling but expands during talking to have the above-described appearance. In any case, conventionally known portable telephones have a limit to miniaturization because a transmitter, a receiver, an operation unit, and a display unit are provided on a front surface of a housing.

[0003]

SUMMARY OF THE INVENTION Regarding the technology for reducing the size of a portable telephone, the present applicant assigns a portion represented by a numeric key or the like to a sliding-type operable member in an operation portion which has conventionally been a keypad. A technology has been already proposed (Japanese Patent Application No. 9-267099) in which the sliding-type operable member is provided on the side surface of the housing (for example, at the position where the thumb of the wearer touches). Japanese Patent Application No. 9
Further, Japanese Patent No. 267099 discloses that by using a wireless type earphone instead of a receiver, the size of a portable telephone can be further reduced, and a portable telephone having a small size that can fit completely in a human palm can be realized. doing.

One of the objects of the present invention is as described in Japanese Patent Application No. 9-267.
By extending a part of the idea shown in Japanese Patent Application No. 099, it is possible to provide a method which contributes to the miniaturization of a portable telephone more than the invention according to Japanese Patent Application No. 9-267099, and furthermore, a hand-held matching type, wristwatch It is an object of the present invention to realize a small-sized mobile phone suitable for carrying.

In order to achieve such an object, the present application proposes an invention relating to a portable telephone provided with an operation unit, an input unit, a receiving unit, and a transmitting unit. Among these functional parts, the operation unit is operated by the user at the time of a response operation for answering a call from another telephone-related device or a call operation for making a call to another telephone-related device. Preferably, a sliding operable member or the like according to Japanese Patent Application No. 9-267099 is used, and the occupied area on the front surface of the housing is small. The input means is a member for inputting a signal to be transmitted to another telephone-related device, for example, a transmitter or a data input port. The receiving means is a member for receiving a self-addressed call and a speech signal emitted from another telephone-related device, and the transmitting means wirelessly transmits a call to another telephone-related device in response to a call operation and during a call. Is a member for wirelessly transmitting a signal input by the input means to another telephone-related device.

One of the features of the present invention resides in that a re-radiation function is provided in the receiving means. That is, the receiving means of the present invention re-radiates a self-addressed call and talk signal wirelessly received from another telephone-related device in a weak electric field. The re-radiated call and talk signals are wirelessly received by a portable device having the function of wirelessly receiving the call and talk signals and carried by the same person, and in this portable device, the person It is reproduced in a form that can be perceived or understood. in this way,
According to the present invention, the wirelessly received call and talk signals are transferred from the portable telephone to the portable device carried by the same person. It becomes possible to abolish the receiver and the like, and to abolish the vibrator and the like provided in the housing, so that the so-called handset can be reduced in size.

Further, according to the present invention, since the portable telephone and the above-mentioned portable device are wirelessly connected, it is not necessary for the carrier to bring his / her ear to the portable telephone during a call. This alleviates restrictions on the usage pattern. Furthermore, compared to a configuration in which a signal line is connected between the portable telephone and the other portable device through a wired connection (for example, a configuration in which a wired earphone is connected to the portable telephone), the signal line for the wired connection is more portable. The present invention is more useful in that it does not cause problems related to usability, such as clinging to the body of a person and troublesome to clear the signal line when not in use. Furthermore, by wirelessly connecting the portable telephone with the other portable device, the distance between the radiating portion of the portable telephone (such as an antenna forming the receiving means and the transmitting means) and the user's ear or brain can be improved. Therefore, it is possible to reduce or eliminate the user's concern about the influence of the electromagnetic wave on the human body, and to alleviate the obstacle to the spread of the portable telephone.

Further, according to the present invention, since the portable telephone and the portable equipment are carried by the same person and the distance between them is at most about several tens of centimeters, the connection between them is limited. May be a weak electric field as described above. Therefore, despite the new technique of re-radiation, the re-radiation has no or no effect on the human body at all.

Further, in the present invention, a receiver, a buzzer, a vibrator, and the like conventionally provided in a portable telephone are detached from the portable telephone, and a function corresponding thereto is transferred to another portable device. Therefore, it is possible to realize a small-sized portable telephone having a convenient appearance, such as a palm-aligned type, a wristwatch type, or the like. That is, the shape of the housing on which the operation unit, the input unit, the reception unit, and the transmission unit are provided on or on the surface thereof,
It can be a round housing that fits in the palm of the user, or a wristwatch-type housing that can be worn on the wrist like a wristwatch. In particular, a wristwatch-type mobile phone can be more easily carried because it does not require a clothing pocket or a special case when carrying. This effect can be further enhanced particularly by using a sliding-type operable member described in Japanese Patent Application No. 9-267099.

According to the present invention, it is possible to prevent the occurrence of new problems such as an increase in the volume of another portable device due to the transfer of functions from the portable telephone to another portable device. That is, by effectively utilizing the functions that the other portable device has conventionally provided, the total volume of the portable telephone and the other portable device can be reduced, and a more portable device can be realized. . In recent years, the same person carries multiple devices simultaneously (for example, PHS
Since a mobile station and a portable CD player are frequently carried around, a portable telephone (PHS in the above example) is used.
It is effective to reduce the overall volume of the mobile station and other portable devices (in the example, a portable CD player) in total to reduce the burden on the user. The present invention relates to a portable information device realized in such a manner, that is, a portable information device in which the portable telephone according to the present invention and the portable device are wirelessly connected by the signal of the weak electric field related to the re-radiation. Such an invention can also be grasped and expressed.

There are several types of portable equipment constituting the portable information device according to the present invention. The first type is
A caller that wirelessly receives a call re-emitted from a mobile phone and emits sound, vibration, or light in response to the call, and wirelessly receives a speech signal re-emitted from the mobile phone and converts the speech signal to sound or text. This is a combination with a handset provided to the user. That is, a wireless type caller is used instead of a conventional portable telephone built-in type caller (buzzer, vibrator, lamp, etc.), and a wireless type handset (eg, wireless This is a configuration using an earphone or a character display device similar to a pager terminal).

In the second type, a call and a speech signal re-radiated from a portable telephone are received by radio, and sound, vibration or light is emitted in response to the radio reception of the call, while a speech signal received by radio is transmitted by a weak electric field. This is a combination of a re-radiating caller and a receiver that receives a speech signal re-radiated from the caller by radio, converts the speech signal into sound or text, and provides the converted sound to a user. One of the differences with respect to the first type is that the handset does not receive the talk signal directly from the portable telephone but via a caller.

A third type is a caller which receives a call and a speech signal re-radiated from a portable telephone by radio, emits sound, vibration or light in response to the radio reception of the call, and outputs the received speech signal by wire. And a receiver that converts a speech signal, which is a wired output of the caller, into sound or text and provides the sound to a user. One of the differences between this type and the second type is that a wired connection is made between the calling device and the handset.

A fourth type is a method of receiving a call and a speech signal re-radiated from a portable telephone by radio and emitting sound, vibration, or light in response to the radio reception of the call, while converting the received speech signal into sound or text. It is a single portable device that is converted to and provided to the user.

Advantages common to these types are a portable broadcast receiver for receiving broadcasts and reproducing audio or text images, a portable audio device for reproducing audio from a portable recording medium, and an image from a portable recording medium. In addition, a portable video device or the like that reproduces audio can be used as the above-described caller (first to third types) or a single portable device (fourth type). That is, these portable broadcast receivers, portable audio devices, and portable video devices all have a function of reproducing and outputting audio or video, and the function of notifying the function according to the reception of a call and a talk signal. Or a function equivalent to a buzzer, etc.
Can be added without additional parts.

Further, in the first and second types, since three separate devices such as a portable telephone, a caller and a receiver are connected only by wireless connection, problems such as clinging of signal lines occur. There is an advantage of not. Further, in a portable broadcast receiver or the like, since a usage mode of converting an audio signal into electro-acoustic sound using a (wired or wireless) earphone and providing the converted sound signal to a carrier is generally used, the second and third sound signals are used.
According to the type, a function corresponding to a handset or the like can be added without extra circuits or parts. Further, since a function of displaying a character on a screen is generally provided in a portable video device or the like, according to the fourth type, a function of receiving a speech signal and displaying a character is provided by a special circuit. add to·
Can be added without additional parts.

[0017] For example, the following is a device for improving the usability of the portable telephone and the portable information device according to the present invention.

First, according to the present invention, a call and a speech signal are re-radiated from a portable telephone with a weak electric field, and are received by another portable device by radio. Therefore, it is desirable to devise a method for enabling the other portable device to appropriately receive the call and talk signals even when the surrounding radio wave environment is not so good. For example, the receiving means of the portable telephone may add an identification code unique to the portable telephone or an identification code unique to the portable device on the receiving side at the time of re-radiation. In this way, for example, when one person is using the mobile phone according to the present invention and another person is also using the mobile phone according to the present invention, the mobile phone is used by one person. It is possible to prevent a portable device (a caller or the like) carried by the other person from responding to the re-radiation from the portable telephone set.

Next, when an interfering wave arrives in a frequency band to which re-radiation from the portable telephone belongs (for example, when another person is using the portable telephone according to the present invention nearby).
It is desirable to devise measures to prevent abnormal operation that may be caused by this interference wave. For example, at the time of re-radiation from the receiving means of the portable telephone, if the spectrum of the signal is spread within a predetermined occupied frequency band, it is easy to eliminate the influence of the interfering wave even when it exists. As a method of spreading a spectrum, a method of directly spreading or frequency hopping using a predetermined pseudo-noise code can also be adopted. There is a method of modulating the frequency or phase of a signal with a modulation factor.

Further, means for monitoring a frequency band to which a signal related to re-radiation belongs may be provided in the portable telephone. That is, although neither a call nor a speech signal is transmitted and received wirelessly with another telephone-related device, an electromagnetic wave (interference wave) having an intensity equal to or higher than a predetermined upper limit level exists in a frequency band to which a signal related to re-radiation belongs. If the re-radiation and the wireless transmission of the call to other telephone-related devices are prohibited during the communication, the possibility that the portable telephone malfunctions due to the interference wave is reduced. Further, it is desirable that the monitoring means be provided with a function of releasing the prohibition of wireless transmission of calls to other telephone-related devices when the carrier performs a predetermined emergency call operation using the operation unit.

It is desirable to provide a means for monitoring the frequency band to which the signal related to the re-radiation belongs in the caller, the receiver, and the like. For example, when an electromagnetic wave of a predetermined upper limit level or more is detected in a frequency band to which re-radiation from a portable telephone belongs, a notification to that effect is given to a wearer in a form that can be distinguished from notification of wireless reception of a call. Further, when an electromagnetic wave of a predetermined upper limit level or higher is detected in a frequency band to which re-radiation from the portable telephone belongs, a process of converting a speech signal into sound or text is prohibited.

As a handset (wired or wireless)
When using the earphone, it is not necessary to reduce the volume in advance to avoid hearing by surrounding people.
In addition, it is desirable that the earphone has a function of collecting sounds emitted in the surroundings in response to an instruction from a wearer and outputting the sounds together with a speech signal. The carrier can listen to the surrounding sounds and sounds while talking, and can interrupt the surrounding sounds and sounds when he / she wants to concentrate on the call.

When the portable device is a device having a sound reproducing function and a sound output function of a call / speech signal, while receiving a call or a speech signal, the received broadcast sound or reproduction from a portable storage medium is performed. It is desirable to provide the portable device with a function of forcibly reducing or blocking the volume of audio. As a result, even when the carrier is listening to the reproduced sound, it is possible to immediately answer the call and start talking in a favorable environment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone according to a preferred embodiment of the present invention will be described below. Note that the same reference numerals are given to configurations common or corresponding to the embodiments, and description thereof will be omitted.

(1) First Embodiment FIG. 1 shows the appearance of a portable telephone according to a first embodiment of the present invention. In this embodiment, an antenna 12 is provided on the top of a slightly rounded casing 10 so as to match with the human palm, and a display unit 1 such as an LCD is provided on the front of the casing 10 in order from the top.
4. It has a structure in which a button 16 pressed by the wearer and a transmitter 18 for converting the sound of the wearer into an electric signal are arranged.

One of the points that this embodiment differs from the structure which has been widely known from the viewpoint of appearance is that the number of buttons conventionally provided on the front surface of the casing 10 is reduced, and That is, only the buttons 16 are provided (three in the figure). This is because a slide switch (for example, a shuttle key having an up contact, a down contact, etc.) 20 is provided on the side surface so that a person can input numbers by operating the slide switch 20. This is because there is no need to provide numeric buttons. A switch other than the slide switch 20, for example, a jog dial, may be used if dimensional restrictions permit.

Another difference in appearance is that a receiver for voice output is not provided. One of the features of the present embodiment is that a receiver is not provided, and more specifically, there is no need to provide a receiver on or inside the housing 10. Furthermore, as described later, in the present embodiment, it is not necessary to provide a member for calling, such as a buzzer or a vibrator, on the surface of or inside the housing 10.

As described above, in addition to the provision of the slide switch 20 to reduce the number of buttons 16,
By providing a buzzer, a vibrator, and the like outside the housing 10, in the present embodiment, it is possible to realize a small-sized mobile phone that can fit completely in a human palm.

FIG. 2 shows a functional configuration of the portable telephone according to the present embodiment. One of the basic functions of a portable telephone is to receive a call transmitted from another telephone-related device, for example, another portable telephone, directly or wirelessly through a base station, and to receive the received call addressed to itself. If the call is a call, the function notifies the carrier of the reception of the call. Under the control of the wireless control unit 24, the remote communication wireless unit 22 receives the wirelessly transmitted call using the antenna 12. Voice control unit 26
When the signal received by the remote communication radio unit 22 is a signal related to a call, this signal or a signal generated based on this signal is transmitted to the near-field communication transmission unit 30 under the control of the main unit control unit 28. Supply. Proximity communication transmitter 30
Modulates a signal from the audio control unit 26 under the control of the main body control unit 28, and radiates this signal with a weak electric field from the antenna 32 provided inside the housing or integrally with the antenna 12. I do. That is, the signal related to the call is re-emitted with a weak electric field.

The other of the basic functions of the portable telephone is that when a person who has been notified of a call performs a response operation or performs a call operation, the person directly or at a base station. This function calls another telephone-related device via a station or initiates a call with the device. The operation unit 34 is the button 1
6 and a slide switch 20 which are operated by the wearer.
This function is realized by controlling the wireless control unit 24 and the like in accordance with an instruction from a carrier supplied via the. Also, while the call is established, the main body control unit 28
The voice control unit 26 receives a signal from the transmitter 18, performs predetermined processing on the signal, and supplies the signal to the remote communication wireless unit 22 under the control of. Let it. In addition, instead of the input from the transmitter 18,
The data signal from the data input port 36 may be transmitted as a wireless signal. In the figure, the data signal is input to the audio control unit 26, but this is only for convenience of illustration.

Further, the portable telephone according to the present embodiment
The presence or absence of an interfering wave in the frequency band to which re-radiation from the near-field communication transmitting unit 30 and the antenna 32 belongs is determined by the antenna 3
In order to perform monitoring and detection by using the monitor 8, a monitoring receiver 40 is provided. In addition, the antenna 3
2 and 38. Monitoring receiver 4
If the level (received electric field strength) of the signal received due to 0 is equal to or higher than the predetermined upper limit level, the main body control unit 28 determines that a high-level interfering wave is present. , It is considered that the re-radiation from the portable telephone according to the above is relatively strong, and the operation related to the wireless transmission and reception including the re-radiation by the short-range communication transmitting unit 30 is prohibited, and the calling operation by the operating unit 34 is performed. And so on.
However, even in this case, emergency transmission is possible.
That is, when the emergency call button 42 in the operation unit 34 is operated, the main body control unit 28 shifts to a state of accepting an operation related to emergency call such as a call operation, and restarts operations related to wireless transmission and reception. The emergency call button 42 is specifically one of the buttons 16.

FIG. 3 shows a functional configuration of a wireless caller suitable for use with the portable telephone according to the present embodiment. The wireless paging apparatus shown in this figure has a paging signal receiving section 44 for receiving a signal radiated from the antenna 32 of the portable telephone by using the antenna 46. The caller controller 48 causes the buzzer 50 to sound or the vibrator 52 to generate vibration when the signal received by the call signal receiver 44 is a signal related to a call. Buzzer 5
0 and the vibrator 52 may be operated together, but in the example of this figure, the buzzer notification mode and the vibrator notification mode can be switched and set by the switch 54 by the wearer. That is, the caller control unit 48 operates one of the buzzer 50 and the vibrator 52 designated by operating the switch 54.

Further, the caller control unit 48 turns on the incoming call lamp 56 when the signal received by the call signal receiving unit 44 is a signal related to a call, and turns on the busy lamp when the signal is a talk signal. Turn on 58. If the level of the signal received by the paging signal receiving section 44 is equal to or higher than the predetermined upper limit level, a high-level interference wave is present = a portable telephone according to the present invention used by another person nearby. It is considered that re-radiation from the user is relatively strong, and the busy lamp 58 is turned on even if no talk signal is received.

FIG. 4 shows a functional configuration of a wireless earphone suitable for use with the portable telephone according to the present embodiment. The wireless earphone shown in this figure uses a signal radiated from an antenna 32 of
And a speech signal receiving unit 60 to be supplied to the voice control unit 64 by using the voice signal. When the signal received by the talk signal receiving unit 60 is a talk signal, the earphone control unit 66 performs processing on the talk signal using the voice control unit 64, and
The sound is output from the speaker 70 via the speaker 8.

The earphone control unit 66 includes a talk signal receiving unit 60
If the level of the received signal is equal to or higher than the predetermined upper limit level, a high-level interfering wave is present = re-radiation from the portable telephone according to the present invention used by others nearby. The sound output is cut off under the control of the sound control unit 64 or the mixer 68, assuming that the user has a relatively strong feeling. The mixer 68 mixes a signal related to the surrounding sound collected by the microphone 72 with a speech signal, and
This allows the wearer to hear surrounding sounds even during a call. However, a function of inhibiting the mixing of the input of the microphone 72 by operating the microphone on / off switch 74 is also provided so that surrounding sounds can be cut off.

As described above, according to this embodiment, the buzzer and the handset conventionally provided in the portable telephone are eliminated,
In place of this, a wireless calling device and a wireless earphone are provided, so that the restrictions on the use form are eased, and the operation of lowering the volume in advance to avoid hearing by surrounding people becomes unnecessary, and the size of the portable telephone is reduced. Can be reduced, and the concern by the consumer that the radiation of the antenna 12 may affect the human body can be solved. Furthermore, since the three separate devices, the portable telephone, the wireless calling device, and the wireless earphone, are connected only by wireless connection, it is troublesome for the cord to cling to the wearer of the carrier and to clear the cord when not in use. It won't be. Further, as shown in FIG. 2, an earphone charging terminal 76 is provided on the mobile phone, and a battery 75 built in the mobile phone is provided.
A battery (not shown) built in the wireless earphone may be charged with a discharge output supplied from the power supply circuit 78 via the power supply circuit 78 or power supplied from an external power supply (not shown) via the power supply circuit 78 and the charging terminal 80. it can. If the dimensional restrictions are relaxed, a conventional handset may be provided.

Further, since the distance between the portable telephone and the wireless calling device and the wireless earphone is about several tens of cm, close-field electromagnetic communication is performed.
The influence on the human body by the re-radiation can be prevented, and the oscillator constituting the near-field communication transmitting unit 30 can have a simple (although slightly unstable) circuit configuration.

Further, two persons sitting next to each other may carry the portable telephone according to the present embodiment. Also, when a call is placed or made on one of the two portable telephones, there is a concern that the other wireless paging device or wireless earphone may react. . However, the distance between a person and his neighbor is usually much larger than the distance between his mouth and ear, that is, the distance between the portable telephone and the earphone during a call. Therefore, even if a signal re-radiated from a neighbor's portable telephone arrives at a person's wireless paging device or wireless earphone, the reception level is the same as when a signal re-radiated from the person's portable telephone is received. The level is only lower than the reception level by 10 dB or more. Therefore,
Problems such as interference and malfunction are unlikely to occur.

In addition, as described above, re-radiation is performed in a weak electric field, and when an interfering wave having a high reception level is received, the busy process is performed accordingly. As a result, it is possible to further suppress the occurrence of troubles such as interference and malfunction. Further, by modulating the signal in the near-field communication transmitter 30 and spreading the spectrum, even when an interfering wave exists, the influence of the interfering wave can be easily eliminated. In particular, by modulating the frequency (or phase) with a high degree of modulation, the circuit configuration can be simplified. For example, if a VHF band is used, the modulation degree may be 10 kHz or more.
In addition, the near field communication transmitting unit 30 adds an identification code unique to the portable telephone or an identification code unique to the portable device on the receiving side to the beginning of the signal to further prevent interference and the like. It can be avoided suitably.

Further, by making the display form by the busy lamp 58 different from the display form when the telephone is actually busy, the wearer can know the superiority and the superiority of the surrounding electromagnetic wave environment. Since the emergency call is made possible in response to the operation of the emergency call button 42, there is no problem such as being unable to make a call in an emergency.

Further, since the wireless earphone is provided with the microphone 72 and its on / off switch 74, it is possible to listen to the surrounding sound and voice while talking, or conversely, to concentrate on the call, the surrounding sound and voice can be changed. It can also be turned off.

FIG. 5 shows a configuration of a circuit that can be used as the monitoring receiver 40, the call signal receiver 44, and the talk signal receiver 60 in this embodiment. For the detailed function and operation of the circuit shown in this figure, please refer to Utility Model Registration No. 526776. In the figure, an antenna 82 is an antenna corresponding to the above-described antennas 38, 46, and 62, and a signal received by the antenna 82 is supplied to an RC filter 86 after being band-limited by a BPF 84. As described above, the received signal is frequency-modulated, and the RC filter 86 converts the frequency modulation into amplitude modulation. The output of the RC filter 86 is amplified by the amplifier 88, rectified by the rectifier circuit 90, further removed of the high-frequency component by the LPF 92, and input to the differential amplifier 94 as a bias voltage. Further, the output of the differential amplifier 94, that is, the demodulated output is low-pass filtered by the LPF 96 and attenuated by the attenuator 98, and then used to control the gain of the amplifier 88 (AGC). In this circuit, while the output of the LPF 92 is small, the differential amplifier 94 operates at the maximum gain.
Therefore, a stable demodulated output can be obtained irrespective of temperature and frequency fluctuations. Further, when the input to the differential amplifier 94 is lower than the predetermined lower limit level, the differential amplifier 94 does not operate, so that radiation from other mobile telephones used far away (that is, having a low reception level) may be captured. Also less. Further, since it is not necessary to use a capacitor having a large capacity, integration into an integrated circuit is easy.

(2) Second Embodiment FIG. 6 shows a configuration of a wireless paging apparatus that can be used in a second embodiment of the present invention. In this embodiment, the call signal receiving unit 44 used in the first embodiment is used.
And a call signal control unit 102 having a function of discriminating a signal type is provided in place of the call signal control unit 48, and further, a call signal for re-radiating the received talk signal. Transmitter 104 and antenna 1 for re-radiation
06 is provided. That is, in this embodiment, when the signal received by the call signal talk signal receiving unit 100 is a signal related to a call, the call control unit 1
02 performs the same operation as that of the call control unit 48 in the first embodiment, and when the signal is a speech signal, performs no processing such as sounding of the buzzer 50 or generation of vibration by the vibrator 52, and Send a talk signal.
On the wireless earphone side, the same circuit configuration as in the first embodiment can be used. However, what is received by the talk signal receiving unit 60 of the wireless earphone is a talk signal radiated from the wireless calling device.

According to this embodiment, the same effects as in the first embodiment can be obtained. Further, by configuring the speech signal receiving unit 60 and the earphone control unit 66 of the wireless earphone so that the wireless earphone does not respond to the speech signal re-emitted from the portable telephone, the relay function by the wireless caller is realized. Therefore, the probability that the wireless earphone erroneously responds to radiation from another portable telephone can be reduced.

(3) Third Embodiment FIG. 7 shows a functional configuration of a wireless calling device that can be used together with a portable telephone in a third embodiment of the present invention, and FIG. 8 shows a functional configuration of an earphone. In this embodiment, a signal processing unit 108 and a wired output terminal 110 are provided instead of the talk signal transmitting unit 104 and the antenna 106 in the second embodiment. Also, as an earphone,
Instead of a wireless earphone including the talk signal receiving unit 60 and the antenna 62, a wired earphone including the wired input terminal 112 is used. That is, in this embodiment, the speech signal among the signals received by the call signal speech signal receiving unit 100 is processed via the signal processing unit 108, and then transmitted through the wired output terminal 110, the code (not shown) and the wired input terminal 112. The audio signal is input to the audio control unit 64 and the earphone control unit 66, and is converted into sound from the speaker 70 and output. As described above, even with a configuration in which the caller and the earphone are wiredly connected, effects such as miniaturization of the portable telephone can be obtained. Further, depending on the circuit configuration, the voice control unit 64, the earphone control unit 66, the mixer 68, the microphone 72, and the switch 74 shown in FIG. 8 can be provided in the caller. In that case, the configuration of the earphone becomes very simple, and low-cost implementation becomes possible.

(4) Fourth Embodiment FIG. 9 shows a configuration of a wireless paging apparatus that can be used together with a portable telephone according to a fourth embodiment of the present invention. The caller shown in this figure is different from the caller according to the second embodiment in that a speech signal transmitter 104 and an antenna 106 are replaced with a character generator 11.
4 and a display unit 116 are provided. In this embodiment, it is possible to provide a caller with information on a speech signal to a portable person without using a wireless earphone or a wired earphone. That is, when the signal received by the call signal talk signal receiving unit 100 is a talk signal, the caller control unit 102 controls the character generating unit 114 to display characters on the screen of the display unit 116. Such a configuration is effective, for example, when implementing the present invention using a portable telephone and a pager terminal. That is, the present embodiment can be realized by adding a function of receiving a call signal and a talk signal re-radiated from the portable telephone to the pager terminal.

(5) Fifth Embodiment FIG. 10 shows a configuration of a pager terminal that can be used with a portable telephone according to a fifth embodiment of the present invention.
