When the user operates the operation unit 10 to instruct erasure of the already stored telephone directory data, an erasure mark is added to the area indicating the parent device erasure of the instructed telephone directory data.
[0028]
Only the telephone directory data in which an erasure mark is not added to the area indicating the parent device erasure can be displayed on the display unit 11, various operations are performed, and the private telephone directory of each child device is Only when the personal identification number set for each is input, it can be displayed on the display unit 11 and various operations are performed. Note that the operation of the slave unit is the same as that of the operation control described above, and a description thereof will be omitted.
[0029]
Next, the operation when updating the telephone directory data by data transfer will be described based on the flowchart shown in FIG.
[0030]
In the standby state, the slave unit is attached to the master unit, and when the attachment to the master unit is detected by the output of the AND circuit 46 (step S1), the main control unit 33 controls the wireless unit 21 to communicate with the master unit. Is established (step S2), and the telephone directory data stored in the telephone directory memory 32 is transferred to the parent device via the wireless channel (step S3), and is stored in the storage unit 13 or the telephone directory memory 14 or the like. The information is stored in the provided temporary storage area.
[0031]
Then, in the main control unit 15 of the base unit, the update date and time data of the common telephone directory and the private telephone directory included in the telephone directory data stored in the temporary storage area and the common telephone directory stored in the telephone directory memory 14 correspond to the updated date and time data. The update is compared with the update date and time data in the private telephone directory of the slave unit (step S4), and when they match, the update is notified to the slave unit (step S5). On the other hand, if they do not match, the telephone directory data stored in the temporary storage area and the telephone directory data stored in the telephone directory memory 14 are compared one by one (step S6).
[0032]
If it is determined that the name included in the telephone directory data being compared is stored in both the telephone directory memory 14 and the temporary storage area (step S7), the telephone number stored in the temporary storage area is determined. It is determined whether or not an erasure mark is given to the book data (step S8). If it is determined that the erasure mark is not given, the phonebook data stored in the phonebook memory 14 or the temporary storage area is deleted. The individual update date and time included in the telephone directory data is adjusted to the newer date and the individual update date and time is updated to the current date and time measured by the clock unit 12 (step S9). If it is determined, the telephone directory data is deleted from the telephone directory memory 14 and the temporary storage area (step S10).
[0033]
At this time, with respect to the telephone directory data stored in the common telephone directory of the telephone directory memory 14, when the deletion mark is given to the telephone directory data stored in the temporary storage area, it indicates the deletion of the slave unit. An erasure mark is assigned to the area and erased when the erasure mark is assigned to all areas indicating the erasure of the master unit and the erasure of the slave unit. The book data may be deleted.
[0034]
On the other hand, in the comparison of the telephone directory data, it was determined that the name included in the telephone directory data being compared was not stored in both the telephone directory memory 14 and the temporary storage area, but was stored only in the temporary storage area. In this case (steps S7 and S11), the telephone directory data is stored in the telephone directory memory 14 together with the current date and time measured by the clock unit 12 (step S12).
[0035]
On the other hand, in comparing the telephone directory data, it is determined that the name included in the telephone directory data being compared is not stored in both the telephone directory memories 14 and the temporary storage area, but is stored only in the telephone directory memory 14. If the erasure mark has not been added to the telephone directory data, it is determined whether or not an erasure mark has been added to the area indicating the deletion of the slave unit (step S13). The book data is stored in the temporary storage area together with the current date and time measured by the clock unit 12 (step S14).
[0036]
Then, the telephone directory data is updated (step S9), deleted (step S10) or added (step S12), or the telephone directory data stored only in the telephone directory memory 14 is deleted in the area indicating the child device deletion. When it is determined that the mark has been given (step S13), it is determined whether or not the comparison has been completed for all items (step S15). When it is determined that the comparison has not been completed, the above-described operation control ( Steps S6 to S15) are performed again, and when it is determined that the processing is completed, if the update, deletion, or addition of the telephone directory data is performed by the above-described operation control (steps S6 to S15), the telephone directory is updated. The update date and time of the common telephone directory and the private telephone directory stored in the memory 14 and the temporary storage area are the current date measured by the clock unit 12. (Step S16), and thereafter, the telephone directory data stored in the temporary storage area is transmitted to the child device (Step S17). Let it.
[0037]
Therefore, according to the operation control described above, after the telephone directory data is changed by manual operation, when the slave unit is mounted on the master unit and charging is started, the telephones of the master unit and the slave unit are adjusted according to the change. The book data can be updated, and the update of the telephone book data can be applied to data erasure.
[0038]
In the operation control, the telephone directory data of the child device is transferred to the parent device and temporarily stored, and the telephone directory data is compared in the parent device. However, the present invention is not limited to this. The telephone directory data may be transferred to the child device and temporarily stored, and the telephone directory data may be compared in the child device, or may be transferred one by one and compared.
[0039]
Also, in the above operation control, it is possible to detect whether the slave unit is attached to the base unit or to the charger, and update the telephone directory data by data transfer when attached to the base unit. Although the telephone directory data can be updated in a state where a wireless line can be reliably established between the parent device and the child device, the telephone directory data can be updated by data transfer even when attached to the charger. Update may be performed.
[0040]
Further, in the above operation control, when the phone book data having the same name is registered in both the master unit and the slave unit, the phone book data is updated so that the phone book data with the latest update date and time is obtained. However, the present invention is not limited to this. Even when the phone book data is stored in either the master unit or the slave unit, the phone book data is updated so that the phone book data of the latest update date and time is obtained. With this configuration, it is possible to prevent the deleted telephone directory data from being restored and effectively use the telephone directory memory without adding an erasure mark.
[0041]
That is, in the above-described operation control, when an instruction to delete the telephone directory data is issued by a manual operation, an erasure mark is given to the telephone directory data, and the telephone directory data with the erasure mark is not used, and the data is deleted. By deleting the phonebook data with the deletion mark added when updating the phonebook data by transfer, the deleted phonebook data was prevented from being restored and the phonebook memory was used effectively. By matching the latest update date and time data with the telephone directory data at the time, it is possible to prevent the deleted telephone directory data from being restored and to effectively use the telephone directory memory without using such an erasure mark.
[0042]
Furthermore, in the above embodiment, the description has been made using a cordless telephone, but the present invention is not limited to this. For example, the present invention can be applied to a communication device having a cordless telephone function such as a facsimile device with a cordless telephone function. Needless to say.
[0043]
【The invention's effect】
As described above, according to the present invention, when charging is started, the control means starts updating the telephone directory data, and updates the telephone directory data of the parent device and the child device, or the telephone directory of the parent device or the child device. When erasure information indicating that there is an instruction to erase the telephone directory data is given to the data, the telephone directory data is erased according to the erasure information, so that the telephone directory data erased by the master unit or the slave unit is deleted. However, it can be prevented from being restored after the update.
[0044]
Further, according to the present invention, by providing the child device with the determining means for determining whether the child device itself is mounted on the master device or the charger, the slave device can reliably communicate with the master device. The telephone directory data can be updated only when the battery pack is attached to the parent device and charging is started.
[0045]
Further, according to the present invention, the date and time when the telephone directory data is registered is stored in the telephone directory memory, and when the charging of the child device is started, the date and time stored in the telephone directory memory are stored in the telephone directory memory. By deciding whether or not to perform data transfer based on the determination as to whether or not there is a match, the phonebook data can be registered by data transfer only when necessary, and the phonebook by data transfer can be registered. When registering the data, the latest date and time can be matched with the stored telephone directory data.
