The memory card reader / writer 102 writes data supplied from the computer 103 into the memory card 101 by reading the data from the memory card 101 by inserting the memory card 101 into the memory slot 102a on the front left side. To be supplied. This memory card 101
It is used in a state where it is inserted into the memory slot 100a on the right side of the portable terminal 100 in normal business.

FIG. 2 shows portable terminal 100 according to the embodiment.
FIG. 2 is a diagram illustrating a hardware configuration of the embodiment.

The CPU 201 includes a first storage unit 202 (hereinafter referred to as a fixed memory 202), a ROM 203, a communication unit 204, a display unit 205,
Like the keyboard 206 as the input unit, it is always connected to the touch panel 207 as the input unit, and is selectively connected to the memory card 208 as the detachable second storage unit.

Here, the CPU 201 performs various calculations and controls the entire portable terminal 100. Also ROM
203 stores a BIOS and the like. The first storage unit 202 stores a program and data including an operating system (OS), and the memory card 208 similarly stores a program and data including the OS. The keyboard 206 is used for data input, and the touch panel 207 is used for menu selection and the like. The input data and menu are displayed on the display unit 205. Note that the same liquid crystal panel also serves as the touch panel 207 and the display unit 205. That is, the touch panel 207 and the display unit 205 are physically constituted by one liquid crystal panel. The communication unit 204 is a transmission / reception module for wireless communication.
By this transmission / reception module, for example, by a simple Internet connection procedure for a mobile phone such as a so-called i-mode,
It can send and receive data or programs by connecting to the Internet. The communication means 204 may be constituted by a modem or the like on the premise that the Internet is used by dial-up connection.

Further, by separately connecting the CMOS memory 209 via the system bus 200, the CMOS memory 209 can be stored in any one of the first storage means 202 and the memory card 208 at the time of storage of a memory status described later and activation of the portable terminal 100. It can be used to store a set value or the like for starting.

FIG. 3 shows a portable terminal 10 according to the present embodiment.
0 is a flowchart showing the entire process.

First, when the power is turned on, the ROM 203
Is executed (S300). Next, a set value of which one of the fixed memory 202 and the memory card 208 to start from is read from the CMOS memory 209, and the read program is started based on the set value.

The memory on the starting side is hereinafter referred to as a main memory, and the memory on the non-starting side is referred to as a sub-memory. FIG. 10 shows a setting screen for setting from which memory to start. At this time, if the set value is in a mirroring state including the program, the program is copied from the main memory to the same address of the sub memory (S301).

The CMOS memory 209 also stores a memory status. The memory status is also stored as to whether the fixed memory 202 and the memory card 208 are in a normal state or a failure state, and whether to write data to the fixed memory 202 or the memory card 208 when mirroring is performed or not. . Here, mirroring means storing data of the same content in a plurality of storage means (in the case of this configuration, the fixed memory 202 and the memory card 208), and when one of the storage means fails, the other storage means This is a process that makes it possible to recover the storage unit in which the failure has occurred by using the data.

When the program is started, first, the control file stored in each of the fixed memory 202 and the memory card 208 is read into the main memory (S3).
02). The control file records a unique number determined by the update time of the last file updated in the data and the number of each file. For example, "20001
0250930250001256 "is recorded.

Next, a match / mismatch between the two control files read into the main memory is determined (S30).
3) If it is determined that there is no mismatch, immediately S307
The process proceeds to the operation menu display. If it is determined that there is a mismatch, the process proceeds from S304 to S305, and the confirmation screen shown in FIG. 5 is displayed on the display unit 205 (S30).
5).

The screen shown in FIG. 5 is a display when the data in the memory card 208 is newer than the data in the fixed memory 202. In the opposite case, for example, a message such as "Data newer than the memory card data is stored in the main body memory. Do you want to copy the memory card data to the main body memory?" Is displayed.

When "detailed display" is touched and selected at the lower left of the screen shown in FIG. 5, a detailed display screen shown in FIG. 6 is displayed. On the detail display screen, the last update time of the data stored in the memory card 208 and the fixed memory 202 and the number of records of each file are displayed. In FIG. 6, the display is displayed so as to be compared vertically, but may be displayed so as to be compared horizontally.

Next, when the copy execution or the reverse copy execution is selected on the screen of FIG. 5, the memory card 208 is moved to the same address of the fixed memory 202 or the fixed memory 202.
Is copied to the same address of the memory card 208, and the data is synchronized (S306). Since the fixed memory 202 and the memory card 208 store the number of records and the last update time for each file, copying is skipped for files in which both the number of records and the last update time match. You can also.

When the data synchronization is completed, the display unit 205
Displays the task menu shown in FIG. 9 (S30).
7). When the user touches the display 205 on which the job menu is displayed, that is, the corresponding portion of the touch panel 207 (S3).
08), the processing branches based on the selection (S309, S309)
316, S318). Based on this selection, a data input process (S310 to S315) and a data communication process (S31)
7), data aggregation processing (S319), and end processing (S32)
0) is executed.

When data input is selected in S308 and S309, a data input screen corresponding to the application is displayed, and data is input from the keyboard 206 or the touch panel 207 (S310). When one data is entered,
When the memory card 208 is inserted into the portable terminal 100, the same data is written to the same address of both the fixed memory 202 and the memory card 208 (S31).
1). When the memory card 208 is not inserted into the mobile terminal 100, data is written only in the fixed memory 202.

Next, the memory card 208 is
If the data is inserted in 00, the data written in both the RAM 202 and the memory card 208 are collated (S312), and it is determined whether or not the data does not match (S313). If it is determined that there is a mismatch, the screen of FIG. 7 is displayed on the display unit 205, and when the “detailed display” portion on the lower right of the screen of FIG. 7 is touched, the screen of FIG. Then, data is synchronized from the memory to the main unit or the main unit to the memory according to the displayed contents (S314).
When the data input is completed and “input processing end” in FIG. 7 is touched (S315), the business menu is displayed again (S307). The process from data writing (S311) to data synchronization process 2 (S314) will be described in further detail below.

FIG. 4 shows the data writing (S311) of FIG.
FIG. 8 is a flowchart illustrating in detail steps from data synchronization processing 2 (S314). First, when one data is input in S310, the latest memory status value stored in the CMOS memory 209 is confirmed (S401, S401).
402), if the data mirroring is OFF (S403), data is written to the fixed memory or the removable memory based on the value of the memory status (S404, S405).

If data mirroring is ON in S402, data is first written to the fixed memory (S406), and then data is written to the removable memory (S407). Next, the written data for one case is read from both the fixed memory 202 and the memory card 208 and compared (S408).

If there is no inconsistency in the read data (S409), the data collation processing for one case is completed, and the process waits for the next input data (S315 → S310). If there is a mismatch in the read data or the read fails (this can also be considered a part of the data mismatch), it is determined whether there is a memory failure (S410, S411), and if it is determined that there is a memory failure Displays a warning message indicating that a memory failure has occurred on the display unit 205 (S41).
2), the value of the memory status stored in the CMOS memory 209 is updated, and the mirroring of data is stopped (S413).

If it is not a memory failure (therefore, a partial data error has occurred), the screen shown in FIG. 7 is displayed on the display unit 205. The content of the data written immediately before is displayed on the screen of FIG. 8 (S414). In FIG. 8, the current month instruction of the customer number 1234579 on the memory card side is 1155, which is smaller than the previous instruction. Therefore, “Main memory →
By touching "Data synchronization with memory card" (S415, S416), the data in the main memory is overwritten on the memory card for the data having a mismatch, and the data is synchronized (S418).

If it is not possible to judge which memory has a data error by looking at the screen shown in FIG. 8, by touching "cancel immediately before" at the lower left of the screen (S
415, S416), the data input immediately before is deleted from both the fixed memory 202 and the memory card 208 (S417). Then, in order to re-input the deleted data, a state of waiting for input data is entered (S315 → S31).
0).
