Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to cordless telephones.

[0002]

2. Description of the Related Art Conventionally, under the Radio Law, the same identification number (hereinafter referred to as ID
(Referred to as a code) is stored, and it is stipulated that only the parent device and the child device having the same ID code are wirelessly connected,
It is also specified that a check code calculated by a BCH code is added to the ID code so that error correction and detection can be performed.

In addition, in a conventional general cordless telephone, it is possible to register a plurality of cordless handsets. As such a plurality of cordless handsets, a cordless handset registered in advance and an additional cordless handset can be added later. There is a cordless handset that can be used (hereinafter referred to as an extension cordless handset). When registering a plurality of slave units to one master unit, in order to allow the user to distinguish and use the plurality of slave units, each slave unit has a specific number (hereinafter referred to as a slave unit). (Referred to as a number), and this slave unit number is stored in each of the master unit and the slave unit similarly to the ID code and check code. For this reason, when the user operates the master unit and tries to make an extension call with a specific slave unit, the master unit can determine whether or not the slave unit exists, and the slave unit that does not exist can be determined. If you call, you can notify the user as an error,
Further, when the existing child device is called, only the child device having the same child device number designated by the user is called from among a plurality of child devices having the same ID code.

In the cordless telephone configured as described above, when the slave unit is registered later in the master unit, the master unit stores the added slave unit number and the expanded slave unit stores Since it is necessary to store the same ID code and check code as the parent machine to be registered and the unregistered child machine number, an extension mode for performing such a storage operation and means for shifting to the extension mode are referred to as the parent machine. I had it with the child machine respectively.

The operation of adding a slave unit to the master unit later will be described below. First, when a specific operation is performed on each of the master unit and the slave unit, the master unit and the slave unit are switched to the expansion mode, and the number of the slave unit to be expanded is requested by the master unit, and the input is made according to the request. The registered number is recognized as the cordless handset number to be registered, and the ID code and check code stored in advance and the cordless handset number input are transmitted.
Then, the ID code transmitted from the parent device in the child device,
When it is determined that the check code and the slave unit number have been correctly received, and when it is determined that the check code and the slave unit number have been correctly received, the received ID code, check code, and slave unit number are stored. Wireless connection is possible.

In addition, when an extension child device once added to the parent device is added to another parent device, the same operation as described above is performed, and the parent device and the child device are switched to the extension mode again to add the extension device. The ID code, check code, and child device number of the new parent device have been stored in the child device.

[0007]

By the way, in the conventional extension cordless telephone of the cordless telephone, since the ID code, the check code and the cordless handset number of the parent unit to be added at the time of the extension mode are written, they are not written. It has been put on the market, and nothing works in that state. Therefore, it is necessary to shift the extension slave unit to the extension mode when the ID code is not written. However,
In the above-mentioned conventional device, there is a problem in that it is difficult to use because a specific operation is always required to shift to the extension mode regardless of these states, and the operation is complicated and difficult to understand. .

An object of the present invention is to provide a cordless telephone capable of easily registering an extension cordless handset.

[0009]

In order to achieve the above object, the invention according to claim 1 comprises a master unit connected to a telephone line, and a slave unit wirelessly connected to the master unit, When the identification numbers stored in the master unit and the slave unit respectively match, in the cordless telephone that wirelessly connects the master unit and the slave unit, the master unit, an operation input means for shifting to the extension mode, While providing a transmitting means for transmitting the identification number stored in advance in accordance with the shift to the extension mode by the operation inputting means, the storage means for storing the identification number in the slave unit and the identification number correctly stored in the storing means. It is provided with a discriminating means for discriminating whether or not it is stored, and a control means for shifting to an extension mode in which the identification number transmitted from the parent device is stored in the storage means based on the discrimination result by the discriminating means.

According to a second aspect of the present invention, the master unit is provided with a detecting unit for detecting an idle slave unit number, and when transmitting the identification signal stored in advance by the transmitting unit, the empty unit detected by the detecting unit. While the slave unit number is also transmitted, the storage unit stores the identification number and the slave unit number transmitted from the master unit.

According to a third aspect of the present invention, the slave unit is provided with operation input means for clearing the stored content of the storage means, and the storage means clears the stored content based on the operation of the operation input means. Is.

[0012]

Therefore, according to the first aspect of the present invention, the operation input means of the master unit is operated and the master unit shifts to the extension mode, whereby the identification number stored in advance is transmitted by the transmission unit. When the discrimination means in the slave unit determines that the identification number is not correctly stored in the storage means, the control means shifts the slave unit to the extension mode, and in such extension mode of the slave unit, the identification transmitted from the master unit. When the received number is stored in the storage means, the received identification number can be registered.

According to the second aspect of the present invention, the operation input means of the base unit is operated and the base unit shifts to the extension mode, whereby the detection unit detects the idle handset number and the transmission unit preliminarily operates. The stored identification number and the slave unit number detected by the detecting means are transmitted. When the discriminating unit in the slave unit determines that the identification number is not correctly stored in the storage unit, the control unit shifts the slave unit to the extension mode,
When the slave unit number and the identification number transmitted from the master unit are received in the expansion mode of the slave unit, the additional slave unit is registered by storing the received identification number and the slave unit number in the storage means. In addition to being able to do so, it is possible to register the slave unit to an empty number.

According to the third aspect of the present invention, the storage means clears the stored content based on the operation of the operation input means, whereby the determination means determines that the identification number is not correctly stored in the storage means, The control unit shifts the slave unit to the expansion mode based on the result of the determination, so that the registered slave unit can be added to the new master unit as an expansion slave unit.

The transmission / reception control unit 19b and the memory read / write unit 19c are controlled, and the operation control unit 19e is configured to determine an empty slave unit number based on the slave unit number read by the memory read / write unit 19c.

The transition operation to the extension mode and the operation in the extension mode in the cordless telephone having the above-mentioned configuration will be described.

First, in the parent device, the memory read / write unit 19c controls the memory 17 to store the ID code,
The operation control unit 1 by reading the check code and the cordless handset number
9e (step F1), and when the expansion button of the operation panel 18 is operated in this state (step F2), the operation panel controller 19d outputs an operation command based on the operation to the operation controller 19e, Operation control unit 19
The e shifts to the extension mode based on the operation command (step F3).

Then, when the operation control unit 19e shifts to the extension mode, the operation control unit 19e discriminates an idle handset number based on the handset number read by the memory read / write unit 19c (step F4). , The younger one of the available slave unit numbers is set as the slave unit number to be registered. If it is determined that there is no unused cordless handset number, an error signal is emitted to the outside and whether or not the cordless handset is added by an external display, and what number to register when adding the cordless handset, etc. Is selected (step F5), and the slave unit number to be registered and the extension mode are canceled by the operation according to the instruction.

After the slave unit number to be registered is set, the operation control unit 19e operates the transceiver control unit 19b, and the memory read / write unit 19c reads the ID code, check code, and setting from the memory 17. The slave unit number that has been output is output to the transceiver 15, and the transceiver 1
After converting the information into a predetermined control signal, the signal 5 is transmitted via the antenna 16 (step F6).

When it is determined that the slave unit has been registered by transmitting / receiving a predetermined signal to / from the slave unit, the ID code, check code and slave unit number transmitted by the memory read / write unit 19c are stored in the memory 17. The writing (step F7) and the extension mode are canceled and the normal mode is set (step F8).

On the other hand, also in the slave unit, the memory read / write unit 8b controls the memory 6 to read the stored ID code, check code and slave unit number, and the ID discrimination unit 8c.
(Step F11), and the ID discrimination section 8c determines whether or not the read ID code is correct (step F12). At this time, when the cordless handset is sold as an extension cordless handset and is in an unregistered / unused state, the memory 6 does not store the ID code, the check code, the cordless handset number, etc. When the memory 8 is controlled by the unit 8c to read the stored contents,
A meaningless data string is read.

Therefore, regarding the read ID code, I
When BCH decoding is performed in the D discriminating unit 8c, when the ID code, the check code, and the cordless handset number are stored in the memory 6, the read ID code is determined to be correct, and the ID code and the check are stored in the memory 6. If the code and the cordless handset number are not stored, it is determined as an erroneous ID code, and the determination result is output to the operation control unit 8e, and the operation control unit 8e uses the extension mode based on the determination result from the ID determination unit 8c. (Step F13).

When the operation control unit 8e shifts to the extension mode, the operation control unit 8e operates the transceiver control unit 8a to receive the control signal transmitted from the master unit, and the received control signal. Is output to the operation control unit 8e. Then, the operation control unit 8e extracts the ID code, the check code, and the slave unit number from the control signal received by the transceiver 2, outputs them to the ID discrimination unit 8c, and performs BCH decoding on the ID discrimination unit 8c to extract them. It is determined whether the ID code is correct (step F14).

When the ID discrimination unit 8c determines that the ID code is correct, the operation control unit 8e outputs the ID code, the check code, and the cordless handset number to the memory read / write unit 8b based on the determination result. At the same time, the memory read / write unit 8b is operated and its ID
The code, the check code, and the cordless handset number are written in the memory 6 (step F15), and the extension mode is canceled to set the normal mode (step F16).

Therefore, when the ID code, the check code, the slave unit number, etc. are not stored in the memory 6 of the slave unit,
When the slave unit is automatically shifted to the extension mode and the master unit operation panel 18 is operated in this state to shift the master unit to the extension mode, the slave unit that has been shifted to the extension mode is set to the extension mode. The slave unit is registered in the master unit, and the slave unit can be registered in the empty slave unit number in the master unit.

In addition, when registering a slave unit whose ID code, check code, and slave unit number are stored in the memory 6 as a new master unit as an additional slave unit, the memory is operated by a predetermined operation on the operation panel 7 of the slave unit. By clearing the contents of 6, the extension slave unit mode can be automatically set.

[0035]

As described above, according to the invention described in claim 1, when the ID number, the check code, and the identification number such as the handset number are not correctly stored in the handset, the extension mode is automatically set. In order to make the transition, when purchasing an extension slave unit and registering it in the master unit, only the master unit needs to be shifted to the extension mode by a predetermined operation by the user. It is possible to simplify the predetermined operation performed by the device and reduce the registration error of the extension child device caused by the complicated operation.

According to the second aspect of the present invention, when registering the additional slave unit, the master unit searches for an empty slave unit number and registers the additional slave unit with the empty slave unit number obtained by the search. Therefore, it is possible to further simplify the predetermined operation performed by the user for registering the additional child device and further reduce the error in registering the additional child device due to complicated operation.

According to the third aspect of the invention, the memory content of the slave unit is cleared by a predetermined operation, and the slave unit is shifted to the extension mode accordingly. Therefore, the slave unit is shifted to the extension mode. A configuration in which a registered slave unit can be registered in a new master unit as an additional slave unit by simply adding a configuration for giving a reset signal to a memory without providing a processing circuit for Therefore, the circuit can be simplified and the cost can be reduced.
