Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone having a power source unit removable.

[0002]

2. Description of the Related Art Unlike wire telephones, portable telephones that can talk to anyone anytime, anywhere have become popular in recent years, mainly by business people. This mobile phone has become smaller and smaller, and it has become easier to carry.
For this reason, people other than mobile phone line usage contractors often use this mobile phone without permission, and line usage charges due to people other than the contractor using the mobile phone. There are various security problems such as the line subscriber having to pay. In order to solve these problems, let the station that calculates the line usage charge know who is using this line, then enable the line usage of this mobile phone and There is a system that slightly collects the line usage fee from the users. It is not possible for the line users to correspond to each mobile phone, but it is possible to talk only when the ID code corresponding to each person who wants to use the line is sent to the base station that connects the mobile phone and the general public phone by exchange connection. The system charges the call charge to the registrant of the personal ID code.

Conventionally, the input method of this ID code is
There have been considered a method of inputting from the ten-key pad provided in the mobile phone and a method of completing the input of the ID code by mounting the ID card in which the ID code is previously stored in the mobile phone.

However, from such a numeric keypad, the ID
The portable telephone which inputs the code has a problem that it is very troublesome that the user has to input the ID code every time a call is made. In order to eliminate such trouble, mobile phones using ID cards have come to be used. Although the user is certainly free from the hassle of entering the ID code for each call,
A person using a mobile phone often carries a spare battery for fear that the power of the mobile phone will be consumed during a call. In addition to that, no matter how small the phone becomes when carrying an ID card, the number of accessories makes it inconvenient for the user to always carry. In addition, the mobile phone requires an insertion portion for mounting the ID card, which complicates the structure.

[0005]

As described above, in order to use the conventional portable telephone, in addition to the battery for supplying the power source, the ID storing the ID code unique to the user is stored.
The card is necessary, and there is a drawback that the user who uses this phone feels troublesome to carry these.

In addition, since the structure of a mobile phone for mounting a battery and an ID card has become complicated and miniaturization has been spurred, the number of parts is large due to the integration of parts. This will hinder miniaturization.

Therefore, the present invention simplifies the structure of the mobile phone by reducing the number of accessories attached to the mobile phone as much as possible, simplifying the input of the unique information indicating the line usage contractor into the main body of the mobile phone. The purpose is to provide a mobile phone.

[0008]

In order to achieve the above object, in the present invention, as a structure of a mobile phone, a mobile phone main body having a transmitting / receiving section and a power source for supplying power to the mobile phone main body are provided. The power supply unit is detachably attached to the mobile phone body. The power supply unit is provided with a storage unit that stores unique information indicating a line usage contractor for supplying to the transmission / reception unit. The mobile phone main body referred to here is the mobile phone excluding the power supply unit.

[0009]

[Function] The power supply unit of the mobile phone is provided with a storage unit that stores unique information indicating a line user contractor. When the power supply unit is attached to the main body of the mobile phone, the unique information is stored in the storage unit. It is read out and transmitted to the transmitting / receiving unit. Therefore, it is not necessary to provide a memory or the like for storing this unique information separately from the mobile phone, but it can be realized compactly, and if the power supply unit is attached to the main body of the mobile phone, this unique information is automatically read. Since it is transmitted to the transmission / reception unit provided in the main body of the mobile phone, it is possible to save the trouble of inputting unique information.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of a portable telephone which is an embodiment of the present invention. The mobile phone 1 is roughly divided into a mobile phone body 2 and a power supply unit 3. This mobile phone main body 2 is, like a general mobile phone,
When you receive a call or make a call, the call button 6 has the same operation as raising the handset when you are on a wired telephone, the push button 7 for entering a telephone number, and talking and listening during a call. There is provided a microphone 4 and a speaker 5, and an antenna 8 for transmitting and receiving radio waves.

In the present invention, the power supply unit 3 is provided with an ID code storage unit for storing an ID code which is unique information of the user, and the power supply unit 3 is used as the portable telephone main body 2.
And sends this ID code to a base station (not shown) via the antenna 8. Then, the base station uses this ID code as the charge for the call using the mobile phone 1.
It is used as information for charging a person corresponding to the D code. That is, there is no need to add a configuration for inputting information for identifying a person who has used the mobile phone 1 separately from the configuration of a normal mobile phone, and the configuration provided for a normal mobile phone can be used. It aims to provide a mobile phone that can be used effectively and can be realized compactly. The operation briefly described above will be described below as a specific configuration with reference to the block diagram of the mobile phone shown in FIG. As shown in the figure, when the power supply unit 3 is attached to the mobile phone body 2 of the mobile phone 1, the power supply 9 of the power supply unit 3 controls the control unit 11 and the transceiver unit provided in the mobile phone body 2. Power is supplied to 12. Then, when the telephone number is input via the push button 7 after pressing the call button 6 provided in the mobile phone 1, these signals are input to the control unit 11. At this time, the signal representing the telephone number is not directly transmitted from the transmitting / receiving unit 12 via the antenna 8, but before that, the control unit 11 outputs the control signal to the ID code storage unit 10. In the ID code storage unit 10 to which the control signal is input, the ID code reading unit 14 reads the ID code stored in the memory 13, and the ID code is output to the control unit 11 via the output interface 15. After that, the control unit 11 transmits the ID code and the signal representing the telephone number from the transmission / reception unit 12 via the antenna 8. The transmitted ID code is handled on the side of the base station (not shown) as information for billing the call from the corresponding line usage contractor. Then, the other party having the transmitted telephone number and the user of the mobile phone can talk via the base station. The user of the mobile phone 1 can talk from the microphone 4 and hear the other party's talk from the speaker 5. The signal processing from the voice to the signal and the signal to the voice is performed by the control unit 11 and the transmission / reception unit 12 as in a general mobile phone. And the antenna 8
These signals are also transmitted and received via.

In the above description, the ID code is transmitted simultaneously with the signal representing the telephone number.
As long as the D code is read from the inside of the power supply unit 3 and transmitted from the antenna 8, it does not matter when the ID code is transmitted. In other words, if this ID code can be used as information for billing from the line usage contractor on the base station side, the original purpose is almost achieved.

Next, a case will be described below in which the power supply is turned off and the power supply unit 3 is charged when a call is made for a certain period of time. In this case, as long as the third party can charge the power source section 3 at any time by anyone of the power source section 3, a person who is not a line user contractor can charge the power source section 3 any number of times to semipermanently It is possible to make an illegal call by using the number 3. Figure 3
This is a device devised for the charger shown in. FIG. 3 shows a block diagram when the power supply unit 3 is attached to the charger 20 and the power supply unit 3 is ready to be charged. The power supply unit 3 has the same configuration as that described so far. First, the ID code input unit 1 provided in the charger 20
From 6, for example, enter the ID code with a numeric keypad or the like. The input ID code is input to the ID code comparison unit 17. On the other hand, the control unit 18 outputs a control signal to the ID code storage unit 10 of the power supply unit 3. I input the control signal
In the D code storage unit 10, the ID code stored in the memory 13 in the ID code storage unit 10 is read from the ID code reading unit 14 and output to the control unit 18 via the output interface 15. ID input to the control unit 18
The code is input to the ID code comparison unit 17. The ID code comparison unit 17 compares the ID code input from the ID code input unit 16 with the ID code input from the control unit 18 for coincidence. This is because if the input ID code and the ID code stored in the power supply unit 3 match, it is found that the power supply unit 3 is the owner. Then, only at this time, the control unit 18 outputs the control signal to the charging unit 19 to bring the charging unit 19 into the operating state. As a result, electricity is supplied from the charging unit 19 to the power source 9 of the power source unit 3, and the power source unit 3 is charged. From the above, even if the power supply unit 3 is lost while being attached to the mobile phone body 2, the mobile phone will be illegally used by a third party until the power supply of the power supply unit 3 is lost. However, after the power supply is turned off, when the power supply unit 3 is charged, the power supply unit 3 cannot be charged unless the ID code is input from the charger 20 and the stored ID code does not match. It is possible to prevent unauthorized use by a third party after recharging the part 3.

In this embodiment, the ID code has been described as an example of the information indicating the line usage contractor, but other alternative information can be realized as long as it is unique information indicating the line usage contractor.

[0016]

As described above in detail, according to the present invention, the storage in which the unique information for identifying the line user contractor is stored in the power supply unit of the portable telephone having the detachable power supply unit. Since the mobile phone body reads the unique information stored in the storage unit and sends it to the base station,
A reading portion for reading an ID card storing an ID code, which has been conventionally required, is not needed in the mobile phone, and the mobile phone can be further downsized. Further, if the power source unit is attached to the mobile phone main body, this unique information is transmitted to the transmission / reception unit provided in the mobile phone main body, which saves the labor of inputting the unique information.
