DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus suitable for use in checking whether or not the initialization of a recording medium has been completed in a portable small computer such as an electronic organizer. It relates to a method.

[0002]

2. Description of the Related Art Generally, a recording medium (magnetic disk, RAM, etc.) used for a computer divides a data storage location into predetermined blocks called sectors, gives each block a unique address, and uses the address to store data. Manage storage locations. However, since a recording medium that has just been purchased has not been divided into such blocks, an initialization operation must be performed to perform this processing.

[0003] However, in a device designed for general individuals to be easily used without requiring special knowledge, the user has no concept of initialization, so that a manual is so described. Some users may not understand this even if they do, and may use it without initializing it. In this case, depending on the operating system, a warning such as "data error" or a warning such as "sector not found" is displayed.

[0004]

However, a user who does not have knowledge of a computer may make a complaint that the device has failed by seeing this warning. It is conceivable to display the message "Please initialize" using the above function.However, since an error has not been initialized on the recording medium, it may have occurred, or it may have occurred during system operation after initialization. Since the computer cannot determine whether the error has occurred, a message for an error that has occurred during system operation and a message for an error that has occurred because initialization has not been performed cannot be made different.

The present invention has been made in view of such a situation, and when a recording medium is used without being initialized, a message prompting initialization can be displayed.

[0006]

SUMMARY OF THE INVENTION In order to solve such a problem, an information processing apparatus according to the present invention checks an initialization state of a recording medium and displays a warning when initialization is not performed. In the device, when the recording medium is initialized ,
It is stored in advance on a storage medium provided inside
It is, recording means for recording a plurality of digits of reciting data less likely to overlap accidentally recording medium, reads the recitation data recorded on the recording medium, and recite data read storage medium
Collating means for collating with recitation data stored in the body
And warning means for displaying that the recording medium needs to be initialized when at least some of the preset digits of the plurality of digits cannot be verified. Features. The information processing method of the present invention is the information processing method of an information processing apparatus that performs a warning display when the check to initialize the initialized state of the recording medium is not performed, at the time of initialization of the recording medium in advance information Inside the processing unit
A recording step of recording a plurality of digits of recitation data, which is stored in a storage medium provided and is less likely to be duplicated by chance, on the recording medium; reading the recitation data recorded on the recording medium, and storing the read recitation data Stored on the medium
A matching step for matching the that reciting data, of the plurality of digits, at least, the matching part of digits set in advance
And a warning step for displaying that the recording medium needs to be initialized when the recording medium can not be obtained.

[0007]

In the information processing apparatus and the information processing method having the above structures, the recorded recitation data is read, and if at least a part of the digits cannot be verified , a message for prompting initialization is displayed. Thus, it can be recognized that even a person without computer knowledge cannot use the computer because of a bad use.

FIG. 1 is a block diagram showing the configuration of an embodiment of an electronic organizer to which the present invention is applied. In FIG.
The input unit 1 incorporates various switches including a power switch, and a signal corresponding to the operation is supplied to the CPU 4 via the interface unit 2. The DC voltage obtained by rectifying and smoothing the AC power is supplied to the power supply circuit 3. The power supply circuit 3 includes a battery 3a therein. When a voltage is supplied from an AC power supply, the voltage is used as an operation power supply in the apparatus. When a voltage is not supplied from the AC power supply, the voltage from the battery 3a is supplied. The voltage is used as an operating power supply inside the device.

A tablet 8, a display unit 9, and a speaker 10 are connected to the interface unit 2, and a CPU 4, a ROM 5, a RAM 6, and a backup memory 7 are connected via a bus line.

The tablet 8 has a transparent touch electrode adhered to the display surface of the display unit 9.
A graphic such as a button displayed on the display unit 9 is used as an input button of the tablet 8. When the operator touches a graphic portion such as a button visible through the transparent touch electrode, a coordinate signal of the touched portion is supplied to the CPU 4 and a predetermined input is performed.

As described above, when the operator touches a corresponding portion of the tablet, a coordinate signal of the corresponding portion is generated. This signal is generated by a pressure change by a pressure-sensitive type or a capacitance type. Some of them may be caused by a change in capacitance due to the above, and either of them may be used.

FIGS. 2 and 3 are flow charts showing the operation of the apparatus shown in FIG. 1. FIG. 2 shows the operation for writing the password and FIG. 3 shows the operation for reading the same. In this example, the data is a 16-digit recitation number that is unlikely to be duplicated by accident,
For example, 16-digit data such as "14159265358789326" is written on the recording medium as a reciting number at the time of initialization, and as a result of reading out the same, if it matches 12 or more digits, it is determined that the recording medium has been initialized. Deciding.

When the matching result of the recitation number is less than 12 digits, it is determined that the initialization has not been performed, and a message for performing the initialization is displayed. Note that the reciting number to be written at the time of initialization is stored in the ROM 5 in advance, and is read one digit at a time at the time of initialization, and is stored in a recording medium (in the case of the embodiment, the RAM 6, the backup memory (RA
M) 7).

When the initialization operation is performed, the initialization is performed according to a procedure determined by the operating system used for the apparatus. (This procedure is not shown, but, for example, in the case of MS-DOS, formatting is performed by a format command. Etc.). Then, at the time of initialization, the recitation number is written to the recording medium by the processing shown in FIG.

First, at step 100, a variable i representing the number of digits of the recite number is set to 0, and at step 101 (recording means), the reciprocal number Ai of the 0th digit is read from the ROM 5 and written on the recording medium as data Si. In step 102, the number of digits i of the recitation number is incremented by one, and in step 103, it is determined whether or not i is smaller than 15.

At this point, i is determined to be smaller than 15 since it has been incremented once, and the flow returns to step 101. And the first digit recitation number is RO
It is read from M5 and written to the recording medium. In this way, the recitation number is written to the recording medium one digit at a time.
The writing of the recitation number ends when the six-digit recitation number is written to the recording medium.

FIG. 3 is a flowchart showing the operation of reading out the collation number written in this way and collating it. In FIG. 3, a variable n representing the number of digits that have been collated is set to 0 as shown in step 200, and
As shown in FIG. 1, a variable i representing the number of digits of the recitation number is set to 0.

Next, as shown in step 202, the i-th, in this case, the 0th recite number S0 among the recite numbers recorded on the recording medium is read out, and the 0th recite number A0 stored in the ROM 5 is read out. To match. If the results match, a variable n representing the number of digits that have been collated is incremented by 1 as shown in step 203, and a variable i representing the number of digits in the recitation number is incremented as shown in step 204.

If it is determined in step 202 that the password read from the recording medium does not match the password read from the ROM 5, step 203 is skipped, and in step 204, only the variable i representing the number of digits of the password is incremented.

Thereafter, in step 205, it is determined whether or not the number of digits of the recitation number has reached 15. If the number of digits has not reached 15, the process returns to step 202 and the above-described processing is repeated to sequentially increase the number of digits of the recitation number. Step 2
05 determines that it has reached 16 digits.

Then, in step 206, it is determined whether or not the variable n representing the number of digits that have been collated has exceeded 11, and 1
If two or more digits have been verified, it is determined that initialization has been completed, and the system is started. However, if the number of collated digits is less than 12 digits, it is considered that the initialization has not been completed, and an initialization message in step 207 (warning means), for example, “Please initialize the recording medium” Is displayed, and the system startup operation is not performed.

When the display for prompting the initialization is given, the user knows that the method of use is bad, not the failure of the machine. become able to.

[0023]

As described above, as described above, the information processing apparatus and
According to the method and the information processing method , the initialization is completed when the password read out at the time of initialization is read out and, for example, the password up to a predetermined number of digits matches the written data. As a result, it is possible to check whether or not the initialization has been completed, so that even if a user who has no knowledge of the initialization uses the device, it is easy to determine whether the device is faulty or the usage method is bad. It has the effect that it becomes possible to do.
