Problems to be Solved by the Invention However, in the above-mentioned conventional cordless button telephone device, the base unit 2a%...2nz slave unit 3a's
...Since the same identification code (hereinafter referred to as ID code) is fixedly assigned to both 3n and 3n to prevent interference with other cordless button telephone devices, there were the following problems. .

+1) Since base units 2a1...2n and slave units 8a%...3n with different ID codes cannot be used together, base units 2a,...
It is necessary to manage the pairing of 2n and slave unit 3a%...3n, which is troublesome.

(2) For example, as shown in FIG. 4 (al), the handset 3a, which has the same ID code (IDI) as the base unit 2a, is talking to the central office line ■, and the handset 3a, which has the same ID code (IDI) as the base unit 2b, Handset 3
b is in the middle of a call with the central office line ■, and now, as shown in Figure 4 fbl, the call with the handset 3a is ended and the handset 3a is in the middle of a call, and is returned to the base phone 3b with a different I5D code. Suppose we did.

Here, the base unit 3b is configured so that the installed slave unit 3a is its own slave unit 3.
Since there is no function to confirm whether or not it is the ID code, when the slave unit 3a is returned, the base unit 3b uniquely disconnects the call held by itself. When handset units 3a%...3n having different ID codes are returned to base units 2a1...2n during a call, the call is erroneously disconnected.

The present invention solves the problems of the prior art as described above, and can automatically initialize the identification codes of the base unit and slave unit. It is not necessary to manage the identification codes of each pair of handset units, and the identification codes can be confirmed between the base unit and handset, so even if handset units with different identification codes are returned. It is possible to prevent accidental disconnection of a call, and if a handset with a different identification code is returned, the identification codes of the base unit and handset can be changed so that they match after the call ends. An object of the present invention is to provide a cordless button telephone device that eliminates the need to return the handset to the base unit from which it was initially set, and that improves the convenience of use. It is.

A combination of pairs is performed. Therefore, at the time of factory shipment and construction, the parent unit ta2a,...2n and the slave unit 3a1
...It is possible to eliminate the need for management of combining 3n into pairs.

Next, the operation of returning the slave units 3a and 3b to the base units 2a and 2b upon termination of a call will be described with reference to the flowchart shown in FIG. 2.

Assume that the slave units 3a and 3b are returned to the base units 8a and 3b after the call ends (step 31). Along with this, base unit 2a
, 2b reads the ID code stored in the memory section of the control section 20 of the handset 3a, 3b that has been returned and placed as described above, and transmits this information via the interface 7, 5. and transmits the information to the key telephone main device 1. Based on this information, the control unit 6 of the button telephone main device 1
Check the ID codes of a and 3b (step 32),
It is determined whether the ID code of the slave device 3a%3b matches the ID code of the original base device 2as2b that has been paired with the above initialization (step 33). At this time, the control unit 6 returns the slave units 3a and 3b to the original base unit 2a s 2 b that has been paired as a pair due to the initialization as described above,
When it is determined that both ID codes match, the parent units 2a, 2b and both slave units 3a are transferred via the interfaces 5 and 7.
, 3b to standby (initialize) state (S1
1 step 34). Accordingly, the main unit 2a, 2tLD control unit 11 transmits the status of the handset 3a, 3b and itself to the key telephone main unit 1 via the interfaces 7, 5 (step 39). Thereafter, the power supplied from the button telephone main device 1 is applied to the charging circuit 12 of the main unit 2a, 2b, the charging terminal 13,
Handsets 3 a z via the charging terminals 22 of handsets 3 a and 3 b
3b battery 21 is charged with power (step 40)
. On the other hand, if the slave unit 3a is not returned to the original base unit 2a with which it is paired after the above initialization, but is returned to another base unit 2b as shown in FIG. 3
3, the control unit 6 of the key telephone main device 1 determines that the ID codes do not match, and subsequently returns the returned base device 2b.
The status of the original slave device 3b paired with the device 3b is checked (step 35). Here, the control unit 6 of the button telephone main device 1 converts the original handset 3b to another base phone 2a in the same manner as described above.
(Step 36), after ending both calls, the built-in 1
9 Rewrite and change the stored contents of the ID code memory 23 to match the returned handsets 3a and 3b, and
Avoid creating multiple base units with the same ID code as a and 2b (step 37). Thereafter, the control unit 6 of the key telephone main unit 1 moves to step 34 to place the parent units 2a, 2b and both slave units 3a, 3b in a standby state in the same manner as described above. In the above step 36, the control unit 6 of the button telephone main device 1 does not return the original handset 3b to another base unit 2a, and the handset 3b also has the paired base unit 2b.
If it is determined that a call is in progress using
A is placed in a standby state (step 38), and the process then proceeds to step 39 described above.

After that, when you return the slave unit 3b to the vacant base unit 2a (
step 31), steps 32, 33, 3 as above
5, 36, 37 and then parent unit 2b-, 2a I
The D code memory 23 is rewritten to match the ID code of the returned handset 3a, 3b, and the process moves to step 34.

Note that, contrary to the above embodiment, the slave units 3a13b1...3
A similar effect can be obtained by providing a rewritable ID code memory 23 in the base unit 2a12b1...2n and changing it to match the ID code of the base unit 2a12b1...2n. By providing the ID code memory 23 in 2a12b1...2n, the handset 3a13b
There is an advantage that the size can be reduced by 1...3n.

Effects of the Invention As described above, according to the present invention, when a child device is placed on a base device, its identification code is written into the rewritable identification code memory section via the interface section, and the initial identification code is changed. Once the settings have been made and the handset is returned to the base unit with a different identification code after the call, the key phone main device will determine the call route based on the handset information sent from the base unit. Control is carried out, and at the end of the 14-day conversation, the identification code in the rewritable identification code memory section can be rewritten so that the identification codes of the parent device and the child device match, and the device can be put into a standby state. In this way, the initial setting of the identification codes of the parent device and the slave device can be performed automatically, and therefore, there is no need to manage the identification codes of each pair of the parent device and the slave device during the production process and installation work. In addition, the identification code can be confirmed between the base unit and handset, so even if a handset with a different identification code is returned, the call path can be controlled by the key phone main unit, preventing erroneous call disconnections. It can be prevented. Additionally, if handsets with different identification codes are returned, the identification codes of the base unit and handset can be changed to match after the call ends. There is no need to return the child device to the parent device, and the convenience of use can be improved.

Further, by providing a rewritable ID code memory on the base unit side, the slave unit can be made smaller.
