【Example】

 Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a telephone device with a memory card according to the present invention. In the figure, 1 is a CPU that controls the entire apparatus, 2 is a ROM that stores programs, 3 is DRAM, 4 is SRAM that stores various data, 5 is a clock section, and 6 is a memory card I / An F section 7 is a memory card including a ROM 7a, a RAM 7b, and a battery 7c for holding data stored in the RAM 7b, and 8 is a printer I / F section. Further, 9 is a display unit composed of an LCD control unit 9a and an LCD unit 9b, 10 is a key unit, 11 is a communication unit, and 12 is a communication unit composed of a modem for data communication. Further, E is a battery for holding the data stored in the SRAM 4 at the time of power failure, SP is a speaker, HS is a handset, L is a telephone line, and SW is a switch for switching the telephone line L to one of the call section 11 or the communication section 12. It is Ji.

In the telephone device with a memory card, when performing maintenance of the device, first, the processing mode is changed to “main body → card mode (data save)” by operating the “arrow key (cursor key)” of the key unit 10. Mode) ”and the operation of the“ execution key ”of the key section 10 to save the data stored in the SRAM 4 in the device to the RAM 7b of the maintenance memory card 7, and after the maintenance is performed, the“ arrow key ” By selecting “Card → Main body mode (data recovery mode)” described below, and pressing the “Execute key”, the data of the memory card 7 is transferred to the device side and restored.

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, the maintenance memory card is inserted into the memory card 1 / F section 6 of the device and connected to the device to be maintained, and the display menu on the device side is activated by a prescribed operation. The menu is displayed on the display unit 9. On the menu screen, the desired processing mode is selected with the arrow keys and the execution key is pressed to immediately execute this processing mode. In step 20, it is determined whether the key input from the key portion 10 is an "arrow key".

If the “arrow key” is pressed and it is determined to be “Y”, the process proceeds to menu selection processing steps 21 to 25 to set a data saving / restoring menu between the device and the maintenance memory card. Execute the process. That is, when the "arrow key" is pressed and "main body-> card mode (data save mode)" ("Y" in step 21), "card-> main body mode (data recovery mode)" is set. On the other hand, if it is “card → main body mode (data recovery mode)” (step 22) (“Y” in step 23), “card side” for ending the maintenance menu and returning to the idle state "End menu" is set (step 24), and when the "arrow key" is pressed, the mode does not correspond to any of the above, that is, in the case of "end menu on card side", "main unit-> card mode (data save mode)" It is set (step 25). After each mode is set in this manner, the cursor display is moved to the newly set mode in step 26, and the processing of the CPU 1 returns to step 20.

If the pressing of the “arrow key” cannot be detected and it is determined to be “N” in step 20, the process proceeds to step 30 and it is determined whether or not the operated key is the “execution 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 whether the next operated key is detected.

Further, when the “execute key” is pressed and it is determined to be “Y” in step 30, the currently selected processing mode is executed. If the currently selected processing mode is “main body → card mode (data save mode)” (“Y” in step 31), the process proceeds to step 32 and a predetermined area of SRAM 4 in the device. Then, the data is saved in the RAM 7b in the maintenance memory card 7. Next, at step 33, a predetermined terminal ID for identifying the model of the device is read from the ROM 2 of the device, saved in the RAM 7b of the maintenance memory card 7, and returned to step 20.

After the data is saved in this way, maintenance of the device is performed. After the maintenance is completed, the "Arrow key" operation is used to select "Card-> Device mode (data recovery mode)" to transfer the data saved on the card side to the device side, and then the "Execute key". When is pressed, it is determined that the “card → main body mode (data recovery mode)” in step 34 is “Y”. In this case, the data transfer to the device side is not performed immediately, and the process proceeds to step 35 to judge the terminal ID 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 in the memory card together with the device data and the terminal ID stored in the ROM 2 are stored. If they are compared with each other and if they match each other, the process proceeds to step 36 and the data is transferred from the RAM 7b of the maintenance memory card to a predetermined area of the SRAM 4 of the apparatus and restored. If the terminal IDs do not match and it is determined to be "N" in step 35, an error message is displayed in step 37 and the process returns to step 20.

Further, assuming that the terminal ID of this telephone device is changed to an ID different from the previous terminal ID as a result of the maintenance, the result of the comparison of the terminal IDs is a mismatch, and “N” is displayed in step 35. If it is determined that the data saved in the card is converted so as to be compatible with the new device based on the changed terminal ID without shifting to the error display in step 37, the “data conversion process” is performed. After executing "," the data recovery process of step 36 may be executed. This "data conversion process" may cause an erroneous dial if the maximum number of dial digits that can be registered differs depending on the model of speed dial data, for example. If it is smaller than the destination, the invalid dial data (blank) is added to the evacuation source dial data, and if the number of dial digits of the evacuation source is larger than that of the recovery destination, the number of extra digits from the evacuation source dial data is added. This is a process that deletes the minute dial data and changes each according to the number of dial digits at the recovery destination. If the processing mode when the "execute key" is pressed is not "card-> device mode (data recovery mode)" but "N" in step 34, "card side menu end" is displayed. Assuming that the RAM 7b in the maintenance memory card is cleared in step 38, the "card side menu processing" is terminated and the idle state is entered.

In this embodiment, when executing the “card → main body mode (data recovery mode)”, the terminal ID previously stored in the RAM 7b of the memory card and the new ROM 2 of the device after maintenance are maintained. The read terminal ID is compared, and if they match, the data is restored. This is for the purpose of preventing data from being mistakenly restored to a different-type device before and after maintenance. Therefore, by making a judgment based on the terminal ID for each device, the original device (after maintenance) It is also possible to permit data restoration only to the device that saved the data to the memory card), and by making this judgment not for each device but for each model, the same device is not the original device. Data may be restored to another device of the same type.

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. Later, it is not necessary to re-register data such as speed dial in the memory inside the device, which reduces the burden on the user. In addition, since the device ID is used to judge whether or not the data can be recovered when recovering the data, if this is judged for each device, the data is mistakenly recovered to another device and the original data (data saved in the memory card) is restored. Not only can it be prevented from being destroyed, but it is also extremely effective in terms of protecting data confidentiality. Also, if the terminal ID is determined for each model, data can be copied to the same model. Therefore, for example, when using multiple same models in an office, etc., speed dial etc. for each device. No need to register / change Furthermore, by storing the maintenance program in the maintenance memory card where data is saved, the ROM capacity in the device can be reduced and it is possible to use it between different models regardless of the device model. ..

[Effect of the device]

 As described above, according to the present invention, memory data can be saved / restored with the telephone device before and after maintenance, and data can be saved during maintenance. In addition, there is no need to re-register data after maintenance, reducing the burden on users. In addition, since the device ID is used to judge whether data can be recovered when recovering data, erroneous transfer of data to another device can be avoided if this is judged for each device, and this is judged for each model and saved. By converting the data, it is possible to copy the data to the same type of device, and as a result, the data registration / change operation for each device becomes unnecessary.
