BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device with a memory card which realizes additional functions by connecting a memory card storing programs and various data.

[0002]

2. Description of the Related Art Generally, a telephone device having a communication function used as a home online terminal can use a memory card as an external storage means for storing various information. In particular, personal information such as personal identification numbers is required at bank terminals, etc., and such information that you do not want to be known to others is stored in the memory of the personal memory card, and the speed dial required when using only the normal call function The data and the data for the low-cost line selection function (LCR) are stored in a memory inside the telephone device.

[0003]

However, when maintenance such as ROM replacement is required in such a telephone device, conventionally, data such as speed dials stored in a memory inside the device is stored in a battery or the like. Despite the maintenance, the data is often destroyed by the maintenance, so that it is necessary to re-register these data by operating the keys of the apparatus one by one after the maintenance. In particular, when using multiple telephone devices of this type in an office or the like, the same data must be registered and changed for each device, and such data registration and change work is a burden on the user. Has become.

[0004]

In order to solve such a problem, the present invention is to connect a memory card having a fixed memory for storing a program and a first variable memory capable of storing various data. In the telephone device with a memory card provided with the second fixed memory and the second variable memory, the data of the second variable memory is stored together with the terminal ID for identifying the telephone device with the memory card. Data saving means for saving data in the first variable memory, data comparing means for comparing the terminal ID saved in the first variable memory with the terminal ID stored in the second fixed memory at the time of data restoration, and the comparing means And data recovery means for transferring the data of the first variable memory to the second variable memory in accordance with the comparison output of. Further, there is provided data conversion means for converting the data in the first variable memory into predetermined data based on the comparison output of the data comparison means.

[0005]

The data in the device is saved to the memory card prior to the maintenance of the telephone device, the terminal ID indicating the device identification is automatically identified after the maintenance, and the data saved in the memory card is restored to the device. You. Also,
After the maintenance, the data in the memory card is converted based on the terminal ID of the device and transferred to the device.

In the telephone device with a memory card, when the maintenance of the device is performed, the processing mode is first changed by operating the "arrow key (cursor key)" of the key section 10 to the "main body → card mode (data saving mode)". Is selected and the data stored in the SRAM 4 in the apparatus is saved to the RAM 7b of the memory card 7 for maintenance by operating the "execute key" of the key unit 10, and after the maintenance is performed, the "arrow keys" By selecting “card → body mode (data recovery mode)” and pressing an “execute key”, the data in the memory card 7 is transferred to the device side and recovered.

Hereinafter, the operation of the CPU 1 of the telephone device with a memory card will be described in detail with reference to the flowchart shown in FIG. First, a memory card for maintenance is inserted into the memory card 1 / F unit 6 of the device and connected to the device to be subjected to maintenance, and a display menu on the device is activated by a predetermined operation. Displayed on the display unit 9. On the menu screen, a desired processing mode is selected with an arrow key and an execution key is pressed, whereby this processing mode is immediately executed. In step 20, it is determined whether the key input from the key section 10 is an "arrow key".

If the "arrow key" is depressed and determined to be "Y", the menu selection processing steps 21 to 2 are performed.
Then, the process proceeds to step S5 to execute a data save / restore menu setting process between the device and the maintenance memory card. That is, if the “arrow key” is pressed and “body → card mode (data saving mode)” (“Y” in step 21), “card → body mode (data recovery mode)” is set. (Step 22) On the other hand, if “card → body mode (data recovery mode)” (“Y” in Step 23), the “card side menu” for exiting the maintenance menu and returning to the idle state "End" is set (step 24), and a mode that does not correspond to any of the above when the "arrow key" is pressed, that is, in the case of "card menu end", "body → card mode (data save mode)" is set. Is performed (step 25). After each mode is set in this way, in step 26, the cursor display is moved to the newly set mode, and the CPU
The process of 1 returns to step 20.

On the other hand, if it is determined in step 20 that the "arrow key" has not been pressed and "N" has been detected, step 3
The process proceeds to 0, and it is determined whether the operated key is an “execute key”. If it is determined that the operated key is not the “execution key”, the key operation is invalidated, and the process returns to step 20 to determine the next key to be operated.

When the "execute key" is pressed,
If it is determined to be “Y” at 0, the currently selected processing mode is executed. If the currently selected processing mode is “main body → card mode (data saving mode)” (“Y” in step 31),
The process proceeds to step 32 to save data from a predetermined area of the SRAM 4 in the device to the RAM 7 b in the memory card 7 for maintenance. Next, at step 33, a terminal ID predetermined for identifying the model of the device is stored in the ROM 2 of the device.
Read from the RAM of the maintenance memory card 7
7b and return to step 20.

After the data is thus saved, the maintenance of the apparatus is performed. And after maintenance is over,
In order to transfer the data being saved to the card side to the device side, "card → body mode (data recovery mode)" is selected by operating the "arrow key", and then the "execute key" is pressed. The “card → body mode (data recovery mode)” of No. 34 is determined to be “Y”. in this case,
The data transfer to the device side is not immediately performed, and the process proceeds to step 35 to determine whether the terminal IDs match. That is, in order to prevent the data in the memory card from being erroneously transferred to the memory of the device of a different model, the terminal ID saved earlier in the memory card together with the data of the device and the terminal ID stored in the ROM 2 are used. If the two match, the process proceeds to step 36, where the data is transferred from the RAM 7b of the memory card for maintenance to a predetermined area of the SRAM 4 of the device and restored. If the terminal IDs do not match each other and are determined to be “N” in step 35, an error display is performed in step 37 and the process returns to step 20.

Also, assuming that the terminal ID of this telephone device has been changed to a different ID from the previous terminal ID as a result of the maintenance, the terminal IDs do not match as a result of the comparison and are determined to be "N" in step 35. If so, step 3
After executing a "data conversion process" for converting data being saved to the card so as to have compatibility with a new device based on the changed terminal ID without shifting to the error display of step 7, Data recovery processing may be executed. This "data conversion process" is used, for example, when the maximum number of registered digits differs depending on the model in the abbreviated dial data, if the dial data is transferred as it is, it will cause an erroneous dial, and the number of dial digits at the save source is restored If it is smaller than the previous one, add invalid dial data (blank) to the save source dial data,
If the number of dial digits at the save source is larger than that at the recovery destination, the extra digits are deleted from the dial data at the save source, and each is changed according to the number of dial digits at the recovery destination. is there. "Execution key"
The processing mode at the time when is pressed is not “card → body mode (data recovery mode)” but “N” in step 34
If it is determined that the "card side menu is ended", it is regarded as "end of the card side menu", and the process proceeds to step 38 to clear the RAM 7b in the memory card for maintenance.

In this embodiment, when executing the "card-> body mode (data recovery mode)", a terminal ID previously stored in the RAM 7b of the memory card and a new read from the ROM 2 of the apparatus after maintenance. The terminal ID is compared with the data, and if they match, the data is restored. This is for the purpose of preventing data from being erroneously restored to a heterogeneous device before and after the maintenance. Therefore, by performing the determination based on the terminal ID for each device, the original device (with the maintenance) after the maintenance is performed. Device that saves data to memory card)
May be allowed to recover data only to the device, and by making this determination for each model, not for each device,
Data of the same model may be restored to a device of the same model different from the original device.

As described above, the memory data can be saved and restored with the telephone device before and after the maintenance, and the data can be saved during the maintenance. The operation of re-registering data such as a speed dial in the memory inside the device later becomes unnecessary, and the burden on the user is reduced. In addition, at the time of data recovery, whether or not data recovery is possible is determined by the terminal ID, so if this is determined for each device,
It is not only possible to prevent the original data (the data saved in the memory card) from being destroyed by accidentally restoring the data to another device, but also extremely effective in terms of data secret protection. If the terminal ID is determined for each model, the data can be copied to the same model. For example, when a plurality of the same model are used in an office or the like, a speed dial or the like for each device may be used. Registration and change operations are not required. Further, by storing the maintenance program in the maintenance memory card to which data is saved, the ROM capacity in the apparatus can be reduced, and
It is possible to use between different types of devices regardless of the type of device.

[0016]

[Effects of the Invention] As described above, in the present invention, memory data can be saved and restored with the telephone device before and after maintenance, and data can be saved during maintenance. In the case where is destroyed, the operation of re-registering the data after maintenance becomes unnecessary, and the burden on the user is reduced. Also, at the time of data recovery, whether or not data recovery is possible is determined based on the terminal ID. If this is determined for each device, erroneous transfer of data to another device is avoided, and this is determined for each model and saved. If data conversion is performed, data can be copied to devices of the same model. As a result, data registration and registration for each device can be performed.
No change operation is required.
