Description

TECHNICAL FIELD The present invention is called a so-called electronic memo pad, and has a function of performing arithmetic processing and a function of registering / calling data. The present invention relates to a method of calling data in a data processing device for automobiles.

BACKGROUND ART Some data processing devices of this type have a secret registration function. In the conventional data processing device having the secret registration function, the registered data cannot be read unless the secret state is released by inputting a predetermined password.

Problems to be Solved by the Invention In a conventional data processing apparatus having such a secret registration function, it is difficult for another person to see the registered password, so that the password is not displayed. Therefore, the user cannot confirm what kind of password is registered, which is inconvenient.

An object of the present invention is to solve the above-mentioned technical problems, and when calling registered data, it is possible to display only predetermined data in a blinking manner to emphasize that the data is important. Another object of the present invention is to provide a password calling method for the data processing device.

Means for Solving Problems The present invention has a secret registration mode in which data cannot be called unless a secret state is released by inputting a password registered in advance, and data is called in the secret registration mode. The registered data will be recalled in sequence, and after all the data have been recalled, the password will be recalled automatically, this password will blink, and this password will be recalled. A password calling method for a data processing device, characterized in that the password can be corrected.

Operation According to the present invention, when a call is made in the secret registration mode, registered data is called sequentially. After all the data has been retrieved, the password is subsequently recalled. Therefore, the operator can reconfirm the password. Further, since the password is called, a partial password changing operation can be performed in this state, and the operability of the password changing operation is improved.

Further, according to the present invention, since the password is displayed in a blinking manner, it can be recognized separately from other displayed data, and the excellent effect that the password can be reconfirmed easily is achieved.

FIG. 4 is a flow chart showing an outline of the operation of the data processing device 1. Display is performed in the display routine of step n1, key reading is performed in step n2, and it is determined in step n3 whether or not there is a key input. If there is no key input, processing such as blinking is performed in step n4, and the process returns to step n2. If there is a key input in step n3, a process corresponding to the key input in step n5 is performed, and the process returns to step n1 to reset the display.

FIG. 5 is a flowchart showing a specific processing operation of step n5 shown in FIG. 4 when the call key 22 is pressed. When the call key 22 is pressed, the process moves from step n3 (see FIG. 4) to step m1 to determine whether or not the telephone mode is set. First flag 1
If 3a is a logic "1", it is determined that the telephone mode is set, and the process proceeds to step m2 to determine whether or not it is in the search state. If the first flag 13a is logical "0" in step m1, it is determined that the operation mode is set, the process proceeds to step m3, the phone mode is switched to and initialized, and the step m2 is performed.
Move on to. In this way, by pressing the call key 22 in the calculation mode, the telephone mode is switched and the search is started. Therefore, in order to switch from the calculation mode to the telephone mode as in the conventional case, the call key 22 can be operated without pressing the mode switching key 23.
Since you can switch to telephone mode by pressing
Operability is improved.

In step m2, it is determined whether or not the search state is set,
If it is not in the search state, the process proceeds to step m4 and the top data of the current mode is searched.

The specific processing operation in step m4 is shown in FIG. That is, in step p1, it is determined whether or not the current mode is the secret registration mode, and the third flag 13c
Is logical "1", it is determined that the secret registration mode is set, and the process proceeds to step p2. At step p2, the head data of the data stored in the secret registration area 5a of the data storage unit 5 is searched, and the routine goes to step m6 (see FIG. 5). When the third flag 13c is logical "0" in step p1, it is determined that the normal registration mode is set, and the process proceeds to step p3. At step p3, the head data among the data stored in the normal registration area 5b of the data storage unit 5 is searched, and step m6 (see FIG. 5).
Move on to.

Referring again to FIG. 5, when the search state is set in step m2, the next data of the current data is searched in step m5. The call key 22 is, for example, the forward key 22.
In the case of a, the data having a new registration order is searched next to the current data.

The specific processing procedure of this step m5 is shown in FIG. Referring to FIG. 7, in step q1, it is determined whether or not the current data is data stored in the secret registration area 5a of the data storage unit 5, and if so, the process proceeds to step q2 and the secret is stored. The next data of the data stored in the registration area 5a is searched. In step q3, it is judged whether or not the next data exists, and if there is no data, that is, if all the data in the secret registration area 5a are called, the data stored in the normal registration area 5b in step q4. The first data in the list is searched and the process moves to step m6 (see FIG. 5). If the current data is not the data stored in the secret registration area 5a in step q1, that is, if the current data is the data stored in the normal registration area 5b, the process proceeds from step q1 to step q5 to perform the normal registration. The next data of the data stored in the area 5b is searched for, and the process proceeds to step m6. If there is data in step q3, the process moves to step m6.

Referring again to FIG. 5, in step m6, it is determined whether or not data exists, and if there is data, the data is read in step m7, and the process moves to the display routine in step n1 for key input. The buffer 11 temporarily stores the data and outputs it as a display signal to the display unit 4 to display the registration data.

When there is no data in step m6, that is, when the calling of all data is completed, the process proceeds to step m8, it is determined whether or not the secret registration mode is set, and the third flag 13
When c is logic "1", the process proceeds to step m9, the password is called from the management information area 5c of the data storage unit 5 and stored in the display buffer 11. At this time,
In step m10, the password display flag 13d is set to logic "1", and the process proceeds to step n1. This causes the entire password display 4 to blink, as will be described later.

When the first flag 13c is logic "0" in step m8, it is determined that the secret registration mode is not set, and step m
At step 11, the telephone mode is returned to the initial state and the process proceeds to step n1.

In this manner, by pressing the call key 22 in the calculation mode, the mode is switched to the telephone mode and the call operation is started. Further, when the search is performed in the normal registration mode, the normal registration data are sequentially read in the order stored in the normal registration area 5b, and when the call key 22 is pressed in the secret registration mode, the secret registration data is changed to the secret registration area. 5a is sequentially read in the order stored, and after all the secret registration data is read, the normal registration data is read and finally the password is displayed. Therefore, in the secret registration mode, all data of the secret registration data and the normal registration data can be viewed, and the secret registration data can be viewed with priority over the normal registration data.
Easy to use. Even if the password is displayed on the display unit 4, only the person who knows the password can set the secret registration mode, so there is no fear that the password will be seen by others.

FIG. 8 is a flow chart showing a specific processing operation of the blinking processing in step n4 described above. As described above, when the call key 22 is pressed, the registered data is called by this, the data is displayed on the display unit 4 at step n1, the key is read at step n2, and the next call key 22 is not operated. Moves from step n3 to step s1. In step s1, a counter (not shown) provided in the control unit 9 performs a blinking time (lighting time or extinguishing time) counting operation. Next, in step s2, it is determined whether or not the lighting time has elapsed. If not, the process returns to step n2 and the key reading operation is performed. When the blinking time has elapsed in step s2, the process proceeds to step s3, and it is determined whether or not there is a cursor to blink. If it does not exist, the process proceeds to step s5, and it is determined whether or not the password display flag 13d is logical "1". If not, the process returns to step n2. When there is no input by the call key 22, the above-mentioned circulation loop is followed, and the registered data continues to be lit and displayed on the display unit 4.

When the registered data is lit and displayed on the display unit 4 as described above, the key 2 is pressed to change the displayed data.
When 7 is pressed, the cursor is positioned on the display portion 41a of the dot display area 41 of the display portion 4. In such a state, since the blinking processing routine has a cursor to be blinked in step s3, steps s3 to s4 are performed.
Move to, turn on or off the cursor, and
Move to 2. Thus, step s1 → step s2 → step n2 → step n3 → step S1 to step s4
→ A circular loop of step n2 is formed, whereby the character or number at which the cursor is positioned blinks. When correcting the data, a new corrected character is input for each blinking character or numeral by operating the numeral keys 21 or the like. This moves the cursor to the next digit and causes the cursor to blink. In this way, the registration data is corrected.

When all the registration data is called, the password is displayed. Since the password display flag 13d is logical "1" in step s5, the process proceeds to step s6, and the entire password displayed on the display unit 4 is turned on or off. , Step n2. During the display of such a password, a circulation loop of steps s1 to s3 → step s5 → step s6 → step n2 to step n3 → step s1 is formed, whereby the password displayed on the display unit 4 is displayed in a blinking manner. .

In this way, the password is called at the very end of the calling of the data and is displayed in a blinking manner, so that the user can easily recognize that it is the password and can reconfirm the password.

Further, when partially correcting the password, a part of the password can be changed by performing the same operation as the normal data correcting operation described above in the displayed state. Therefore, the operability of changing the password is improved and the usability is improved.

Although the password is made to blink in the above embodiment, other important data may be made to blink.

Effect As described above, according to the present invention, when data is called in the secret registration mode, registered data is sequentially called, and after the calling of all data is completed, the password is continuously called. Therefore, the password can be reconfirmed. Further, it becomes possible to perform the password changing operation while the password is being called, and therefore the operability of the password changing operation is improved.

Since such a password call display is automatically performed, and therefore a key operation only for calling the password is not required, the effect of good operability is also achieved.

Further, according to the present invention, the effect that this password can be corrected while being called and displayed, and thus the password can be easily updated, is also achieved.
