DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone capable of arbitrarily adding a slave unit, and more particularly to a method of adding a slave unit.

[0002]

2. Description of the Related Art Recently, cordless telephones in which one master unit is combined with several slave units are commercially available.
Furthermore, it is possible to add additional slave units arbitrarily. To add an additional unit, if both the master unit and the slave unit are set to the extension mode and the expansion operation is performed in a predetermined order, the master unit and the slave unit can be distinguished from each other. The exchange of data including the code is performed, the child device data is stored in the memory of the parent device, and the parent device data is stored in the memory of the child device.
After registration, the master unit compares the data sent from the slave unit with the slave unit data stored in the memory, and the slave unit stores the data sent from the master unit and the memory in the memory. The data is compared with the parent device data, and a wireless communication between the parent device and the child device or a communication with the other party via the telephone line from the child device via the parent device can be performed by matching the data.

In a home where a plurality of telephone lines are provided, for example, when a user wants to reconnect an additional child device registered as a parent and a child to a certain parent device to another parent device, for example, etc. In consideration of such usage and the like, in the conventional method of adding a slave unit, the memory contents of the slave unit are updated, that is, the master unit is updated by performing a normal addition operation between the slave unit and an arbitrary master unit. The device data is rewritten so that the parent device can be registered between the child device and an arbitrary parent device.

[0004]

As described above, according to the conventional method of adding a slave unit, even if a slave unit that has been registered as a parent and child by an extension operation is operated with another arbitrary master unit, another slave unit can be added. Because it is possible to re-register with the parent machine, for example, as a service to customers in a restaurant, if you can make a telephone at the rental table, if you inadvertently remove the child machine, there is a concern that There is a problem that the service cannot be used for various services and its use is restricted.

[0005]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above problems, the master unit data to perform the exchange of respective data between the master unit and the slave unit Te to an expansion mode Oite in the memory of said child machine, a Mataue Noriko machine data to the cordless phone to register a parent-child relationship between them by storing each in a memory of the base unit, said child

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below in detail.

FIG. 1 is a flow chart of a method for adding a cordless telephone handset according to an embodiment of the present invention when adding a cordless telephone, FIG. 2 is a flowchart when the data is deleted, and FIG. The figure is shown.

In FIG. 3, a base unit 1 includes a line unit 2 connected to a telephone line including an incoming call detecting unit and a line closing unit.
A handset having a speaker 4 and a microphone 5; a transmitting / receiving unit 6 for exchanging signals with a slave unit to be described later; an antenna 7; The system includes a key input unit (switch group) 8 having function keys and the like, a memory unit 9 for storing data including an identification code, and a control unit 10 for controlling each of the above units.

On the other hand, the extension slave unit 11 includes a transmission / reception unit 13 for exchanging signals with the transmission / reception unit 6 of the base unit 1 via the antennas 7 and 12, and a sound control unit for controlling a sound signal. A key input unit (switch group) 15 having dial keys, function keys, and the like; a memory unit 16 for storing data including an identification code; and a control unit 17 for controlling the above units. It has a microphone 18 and a speaker 19.

Next, a method of adding a slave unit in the cordless telephone will be described. Now, the child device 11 is
For example, if the user wants to add or register as the third slave unit, the slave unit 11 selects the expansion mode by operating a predetermined key on the key input unit 15. Then
The control unit 17 detects that the extension mode has been selected based on a signal from the key input unit 15, reads out a program for the extension mode, and executes the extension operation thereafter.
The operation will be described with reference to the flowchart shown in FIG.

In the extension mode, whether the extension mode is the normal extension mode or the one-time extension mode (the slave unit extension method according to the present invention) is selected (step m1). If it is assumed that the normal extension mode is set, it is confirmed that there is no registration in the one-time extension mode (step m2). Key. If it is the third time, the number "3" is keyed in (step m3), and a password for confirming the master unit is further keyed in (step m4). Then, the control unit 17 temporarily stores the slave unit number and the password, and
The process shifts to a standby state of waiting for data from the master unit 1 (step m5).

Next, when the expansion mode is selected by a predetermined key operation on the key input section 8 of the base unit 1, the control section 10 detects that the expansion mode is selected by a signal from the key input section 8, Thereafter, a program for the extension mode is read to execute the extension operation. As shown in the flowchart of FIG. 1B, after selecting the extension mode, the slave unit number input on the slave unit side by key operation is selected. And the same number as the password. Then, the control unit 1
“0” temporarily stores the slave unit number and the password entered by the key input (steps n1 and n2), the slave unit number and the security number, and an identification code unique to the master unit and predetermined to the master unit. The base unit data including the data and the like is wirelessly transmitted via the transmission / reception unit 6 and the antenna 7 (step n3), and thereafter, the process shifts to a data standby state from the slave unit 11 (step n4).

The master unit data transmitted from master unit 1 is received by antenna 12 of slave unit 11 and transmitted and received by transmitting / receiving unit 13.
Is input to the control unit 17 via the
In response to the reception of the master unit data, the slave unit data and the personal identification number temporarily stored, and the slave unit data including the identification code unique to the slave unit that is predetermined for the slave unit are transmitted and received by the transmitting / receiving unit 13. While transmitting wirelessly via the antenna 12 (step m6), the other party is confirmed by collating the slave unit number and password included in the master unit data with the previously stored slave unit number and password. Then, after the other party is confirmed, the identification code included in the parent device data and the fact that the device is the third child device with respect to the parent device are stored (step m8).

On the other hand, the slave unit data transmitted from the slave unit 11 is received by the antenna 7 of the master unit 1 and is input to the control unit 10 via the transmission / reception unit 6. (Step n), the slave unit number and the password included in the slave unit data are compared with the previously stored slave unit number and the password to confirm the other party (step n).
5) After confirming the partner, the identification code included in the slave unit data is stored in the memory unit 9 as the identification code of the third slave unit (step n6).

With the above operation, the master unit 1 and the slave unit 1
After the registration, the master unit 1 checks the identification code sent from the slave unit 11 with the slave unit identification code stored in the memory unit 9, and checks the slave unit 11. The master device identification code sent from the master device 1 is compared with the master device identification code stored in the memory unit 16, respectively.
A wireless communication between the parent and child, a telephone call from the child device via the parent device via the telephone line, and the like can be performed by matching the identification codes.

In such a normal extension mode, the data collation is performed only with the key number and the personal identification number to be keyed, so that the parent-child relationship registered in the normal extension mode can be arbitrarily changed. Now, for example, when it is desired to add a slave unit having a registration relationship with the master unit A to another master unit B, the registration procedure in the normal extension mode described above is performed between the slave unit and the master unit B. Is updated from the identification code of the master unit of A to the identification code of the master unit of B, and the identification code of the slave unit is registered in the memory unit of the master unit of B. , The parent-child relationship between the two is registered.

Next, a method of adding a slave unit in the one-time addition mode will be described.

First, in the slave unit 11, the key input unit 15
The extension mode is selected by a predetermined key operation in and the one-time extension mode is subsequently selected by a key operation (step m1). Thereafter, in the slave unit 11, steps p2 to p
Step 5 is performed, and then in the base unit 1, steps n1 to n5 are performed in the same manner as in the normal extension mode described above. Further, steps p6 to p8 are performed in the slave unit 11, and step n5 is performed in the base unit 1. , N6, the child device 1 is registered with the parent device 11 in the one-time addition mode.

The contents of steps p2 to p8 are substantially the same as the contents of steps m2 to m8, and a description thereof will be omitted. However, in step p6, the slave unit data transmitted to the master unit once includes a code indicating the one-time addition mode in addition to the slave unit number, the password, and the identification code. The memory unit 9 stores a slave unit number, a slave unit identification code, and a code indicating the one-time addition mode. On the other hand, a code indicating the one-time addition mode is also stored in the memory unit 16 of the slave unit 11 together with the slave unit number and the identification code.

Therefore, once the slave unit 11 is added to the master unit 1 once in the extension mode, the slave unit 11 is not only connected to other master units not in the parent-child registration relationship but also to the master unit in the parent-child registration relationship. Also, the contents of the memory unit 16 cannot be rewritten, and the registration relationship cannot be changed. That is, in the normal extension mode, in step m2, and in the one-time extension mode, in step p2, it is determined whether or not registration has been performed in the one-time extension mode. Become.

The slave unit 11 once registered in the one-time extension mode
If it is desired to change the registration relationship, the contents of the memory unit 16 of the slave unit 11 need to be erased, and the erasing operation is performed according to the flowchart shown in FIG.

In the slave unit 11, an erase mode is selected by a predetermined key operation on the key input unit 15. Then, the control unit 17 detects that the erasing mode is selected by the signal from the key input unit 15, and thereafter reads out the erasing mode program to execute the erasing operation.

In the erasing mode, the slave unit number set at the time of registration is entered by a key (step s1), and a password for confirming the master unit is further entered by a key (step s2). Then, the control unit 17 temporarily stores the slave unit number and the password, and shifts to a standby state waiting for data from the master unit 1 (step s3).

Next, in the base unit 1, when the erase mode is selected by a predetermined key operation on the key input unit 8, the control unit 10 detects that the erase mode is selected by a signal from the key input unit 8, Thereafter, the program for the erase mode is read to execute the erase operation.

After selecting the erasing mode, the same numbers as the slave unit number and the password entered on the slave unit side are sequentially input by key operation. Then, the control unit 10 temporarily stores the slave unit number and the password entered by the key input (step r1,
r2), wirelessly transmits master unit data including a slave unit number and a password, an identification code unique to the master unit, and a code indicating registration in the one-time addition mode via the transmitting / receiving unit 6 and the antenna 7 ( Step r3), and thereafter, a transition is made to a data standby state from the slave unit 11 (step r4).

The master unit data transmitted from master unit 1 is received by antenna 12 of slave unit 11 and
Is input to the control unit 17 via the
In response to the reception of the master unit data, the slave unit data including the temporarily stored slave unit number and personal identification number, an identification code unique to the slave unit, and a code indicating registration in the single extension mode are transmitted and received. 13. While transmitting wirelessly via the antenna 12 (step s4), the remote unit number and password included in the base unit data are compared with the previously stored remote unit number and password to identify the other party. Confirm (Steps
5), after confirmation of the other party, data such as an identification code included in the master unit data, a slave unit number for the master unit, and a code indicating registration in the one-time extension mode, and an identification code of the master unit stored in the memory unit 16 Collate with data such as (s
6) As a result, when all data match, the contents of the memory unit 16 are erased (step s7).

On the other hand, the slave unit data transmitted from the slave unit 11 is received by the antenna 7 of the master unit 1 and is input to the control unit 10 via the transmission / reception unit 6. (Step r), the slave unit number and the password included in the slave unit data are compared with the slave unit number and the password previously stored temporarily to confirm the other party.
5) After identification of the other party, data such as an identification code, a slave number and a code indicating registration in the one-time extension mode included in the slave data, and data such as an identification code of the slave stored in the memory unit 9 (R6), and when all the data match, the contents of the memory unit 9 are deleted (step r7).

By the above operation, all data related to registration in the single extension mode stored in the memory units 9 and 16 of the master unit 1 and the slave unit 11 are deleted. After erasing,
As is apparent from the above-described erasing operation in which the slave unit 11 can be additionally registered to another desired master unit, the contents of the memory unit 16 of the slave unit 11 are erased between the master unit and the master unit not having a parent-child registration relationship. At this point, the data such as the identification code becomes inconsistent and cannot be erased.

Therefore, when the cordless telephone handset is used, for example, for a table service for a restaurant customer, it is necessary to register once in the extension mode and to make sure that the extension cannot be registered with another base unit. If the user is informed by the above method, the child device will not be taken away and can be used for the service with confidence.

The present invention is not limited to the embodiment described above and shown in the drawings, but it is needless to say that the present invention can be appropriately modified and implemented without departing from the scope of the invention.

[0033]

As described above , according to the present invention , the child device
The parent device data stored in the memory is
Unless erased by exchanging data,
Child units registered as parent and child cannot be registered as parent and child units with other parent units
If the child unit registered as a parent and child is
If removed, another parent of the removed child device
Parent-child registration to the machine can be prohibited. Thus, for example, when you use the telephone service to the customers in the restaurant, that can not be connected to the other of the parent unit, if tighten known in advance some kind of way, the less concern that the handset is taken away, as well as anti-theft measures are effective, can be used with confidence in services, etc. to customers.
