PURPOSE:To prevent data from being lost even when the battery of a memory card runs out by providing a control means to receive the data from the mem ory card again at every constant time and to keep them in a keeping means again. CONSTITUTION:A main controller MCU 9 knows that an electronic notebook 41 is connected to a dedicated telephone set 21 by polling and knows the identifi cation number of the electronic notebook 41. Next, the MCP 9 retrieves a mem ory 5 to know whether information to the identification number is already registered or not, and when it is already registered, how long elapses the time from previous renewal time is observed according to the previous updating time registered in the memory 5 and to the present time of a timer 7. When it elapses more than one day, the MCU 9 requires the transmission of data to a dedicated telephone set 29, sucks up the whole data of the electronic note book 41 to the memory 5 and records the whole data and the date information of the timer 7 corresponding to the identification number. Thus, the loss of the data of a memory card can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for storing data on a memory card.

[Prior Art] Conventionally, there have been devices that operate using data on a memory card. For example, there were telephones that stored speed dials on memory cards, copiers that stored facsimile and copy modes, and cameras that stored shooting modes.

[Problem to be solved by the invention] However, memory cards generally operate on dry cell batteries, and there is a risk that data will be lost if the batteries run out.

[Means for Solving the Problems] The present invention provides a receiving means for receiving data from a memory card, a storage means for storing the received data, and a storage means for re-receiving data from the memory card at regular intervals. By providing a control means for re-storing the data, data is prevented from being lost even if the battery of the memory card dies.

is a dry cell battery that powers each component of the electronic notebook.

Here, the operation of this system will be explained. First, the main device
Data transmission between the main unit and the dedicated telephone is based on the volink/select link method from the main unit. At this time, information from the electronic notebook 41 is sent to the main device 1 as a bow link response, as well as information such as the press of the key from the dedicated telephone.

Next, data transmission between the dedicated telephone 21 and the electronic notebook 41 is performed, or signal control similar to R5-232C is performed. This causes the data sending side to output a transmission request signal and send the data over the data line.

In such a system, when a user searches for one of the telephone numbers stored in the memory 45 of the electronic notebook 41 and makes a call operation, the number data is sent to the main device l via the dedicated telephone 41121 and is sent to an outside line. It will be sent in a suitable format.

Note that there are various possible formats for the data exchanged between the main device, the dedicated telephone, and the electronic notebook.

Further, in this system, it is assumed that each electronic notebook has a unique identification number, and the main device Ml recognizes this number and implements various functions.

For example, an identification number is used instead of an extension number to realize functions such as connecting an extension call.

The dedicated telephone controller 29 of the dedicated telephone 21 detects whether the electronic notebook 41 is set using the electronic notebook interface 28.

Then, if there is a bow link from the main device l, the input device 24
Whether or not the electronic notebook 41 is set and the identification number of the electronic notebook 41 inputted from the electronic notebook interface 28 are returned to the main device 1 together with the key code from the main device 1.

Now, the operation control of this embodiment will be explained along the flow shown in FIG. 3. The contents of this control information are held in the control information memory 6.

It is assumed that the main device control unit (MCU) 9 operates accordingly.

MCU9 uses Step Sl to create an electronic notebook 4 using the Bor link.
1 is connected to the dedicated telephone 21, and the identification number of the electronic notebook 41 is obtained in step S2.

Next, in step S3, the MCU 9 searches the memory 5 to see if information regarding the identification number of the lever has already been registered, and if new information is found, the process advances to step S5. On the other hand, if it has already been registered, the process proceeds to step S4, and it is determined from the previous update time registered in the memory 5 and the current time of the clock device 7 whether an amount of time has elapsed since the previous update. . An example here is that if more than a day has passed, step S
On the other hand, if the time has not elapsed, the process advances to step S7.

In step S5, the MCU 9 requests the dedicated telephone control device 29 to send data, sucks up all the data in the electronic notebook 41 to the memory 5, and in step S6, sends all the data and the date and time information of the clock device 7 according to the identification number. Record. An example of this format is shown in FIG.

After this, the operation state using the electronic notebook is entered from step S7. Note that the time to be compared in step S4 is not limited to a fixed value, and may be freely set by the user in the memory 5 using the input device 24 of the dedicated telephone.

Further, in step S4 of FIG. 3, when a certain period of time has elapsed since the last update, a message to that effect is displayed on the display device 23 of the dedicated telephone 21 connected to the electronic notebook 41,
Memory 5 where all data can be rewritten by user operations
It may also be kept at .

Further, even if the dedicated telephone does not have the electronic notebook interface 28 built-in, it may be an external attacher type.

Furthermore, data in the memory 45 can be saved from any of a plurality of dedicated telephones.

Furthermore, the present invention is not limited to telephone systems, but can also be applied to telephones, facsimile machines, copying machines, and cameras that have a memory for storing data on a memory card.

Further, the electronic notebook does not need to be provided with a display device or an input device. In this case, the input device 24 of the dedicated telephone 21
You can register and change data from .

As explained above, by controlling the retention in the rewritable memory 5 based on the date and time information, the rewritable memory 5 possessed by the telephone exchange device 11 can be used as a backup memory for electronic notebook data, and when the battery of the electronic notebook runs out. It can deal with errors and incorrect data changes.

That is, by inputting the identification number from the input device 24 and inputting the transfer of data from the memory 5 to the memory 45, the data can be restored again after replacing the battery.

[Second Embodiment] In this embodiment, data is saved in the memory 5 when the data in the memory 45 is rewritten.

The configuration of this embodiment is the same as that in FIG. 1, and the operational flow of this embodiment is shown in FIG. 4.

When data is registered or changed from the input device 44 to the memory 45 while the telephone is not set to a dedicated telephone, that fact is stored in the memory 45. Dedicated telephone control device 29
When detecting that the electronic notebook 41 has been set, the memory 45 checks whether the data has been newly registered or changed.
(step 511), and if it has been changed, the electronic notebook 41 is requested to transmit the changed data (step 512), and is stored in the memory 5.

Further, when data is registered or changed from the input device 44 or 24 while the dedicated telephone is set, it is immediately stored in the memory 5.

Similarly to the first embodiment, this embodiment is not limited to telephones;
The electronic notebook only needs to have at least a memory.

[Effects of the Invention] According to the present invention, it is possible to prevent the loss of data on a memory card, improve the reliability of the memory card, and enable safe use of the memory card.
