Description

[Detailed Description of the Invention] Industrial Application Field The present invention is referred to as a so-called electronic memo pad, and has both the function of performing arithmetic processing and the function of registering and recalling data. I was inspired by the data access method used in portable data processing devices.

BACKGROUND ART Some data processing devices of this type are equipped with a secret 20 function. In conventional data processing devices having this secret registration function, registered data cannot be read unless a predetermined password is entered to release the secret state.

Problems to be Solved by the Invention Conventional data processing devices equipped with such a FA secret access function are configured so as not to display the passwords, since it would be a problem if the registered passwords were to be seen in the bubbles. There is. Therefore, the user cannot confirm what kind of password has been registered, causing inconvenience.

An object of the present invention is to solve the above-mentioned technical problem, and when calling registered data, only predetermined data can be displayed blinking to emphasize that only one piece of data is required. An object of the present invention is to provide a data display method for a data processing device.

Means for Solving the Two Problems The present invention provides: a key input means; a data storage section for storing data input by the key input means; and a data storage section for storing data inputted by the key input means. A data processing vcr1i characterized in that the data processing vcr1i has a display means for displaying data, and when displaying the data stored in the data storage section on the display means, only predetermined data is displayed without λχ This is a data display method.

Function According to the present invention, only predetermined data is displayed blinking when the registered data is recalled. This allows only important data, such as pass food, to be displayed blinking, thereby emphasizing the importance of that data. Therefore, it is possible to understand at a glance that it is a password by the blinking display, and it is also possible to reconfirm and change the password easily.

FIG. 4 shows data processing rcr! 3 is a flowchart showing an outline of the operation of L1. A display is performed in the display routine of step n1, a key is read in step n2, and it is determined in step n3 whether or not there is human power to press the key. Step n4 if there is no key manpower
Processing such as blinking is performed at step n2, and the process returns to step n2. Step n5 if there is key manpower in step n3
Processing is performed according to the key input in step n.
1 and the display is reset.

Figure Pt55 is a flowchart showing the specific processing operation of step n5 shown in the fourth figure 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 @1, where it is determined whether or not the telephone mode is set. 1st
7 lag 13a is the argument! ! ! If it is "1", it is determined that the telephone mode is in effect, and the process moves to step m2, where it is determined whether or not it is in the search state.

At step l111, Pt517 lag 13a is logic “0”
If so, it is determined that it is in calculation mode, and tq is disconnected, and step l1
13, it is switched to telephone mode and initialized,
Move to step a+2. In this way, in the calculation mode, by pressing the call key 22, the telephone mode is switched and a search is started.

Therefore, it is possible to switch to the telephone mode by pressing the calling Jf-22 without pressing the mode switching key 23 in order to switch from the calculation mode to the telephone mode as in the conventional case, thereby improving operability.

In step 2, it is determined whether or not the search state is in effect, and if the search state is not in the search state, the process moves to step l114, and the leading data of the current mode is searched.

The specific processing operation in step m4 is as follows.
As shown in the figure. That is, in step p1, it is determined whether the current mode is the secret registration mode or not, and the 37th
When the lag 13c is logic "1", it is determined that the secret registration mode is in effect, and the process moves to step p2. step p2
Then, the first data among the data stored in the secret climbing area 5a of the data storage section 5 is searched, and the process moves to step m6 (see figure fjS5). When the 37th lag 13c is logic "0" in step p1, it is determined that the mode is the normal registration mode, and the process moves to step p3. step p
In step 3, the first data of the data stored in the normal registration area 5b of the data storage section 5 is searched, and the process moves to step m6 (see FIG. 5).

Referring again to FIG. 5, if the search state is in step theory 2, the next theme of the current data is determined in step 5.
Evening is searched. When the call key 22 is, for example, the progressive key 22a, data with the latest entry order after the current data is searched.

The specific processing procedure of step II5 is shown in FIG. Referring to FIG. 7, in step q1,
Whether the current data is data stored in the secret registration area 5a of the data storage unit 5 is 1! If so, the process moves to step q2, and the next data among the data stored in the secret registration area 5a is searched. In step q3, it is determined whether or not the next data exists, and if there is no data, that is, if all the data in the secret registration OR area 5a has been called,
In step q4, the first data of the data stored in the normal registration area 5b is searched, and in step mG
(See Figure 5). If the current data is not stored in the secret registration area 5a in step q1, that is, if the current data is data stored in the normal nD'a area 51+, steps q1 to q5 are performed. Then, the next data among the data stored in the normal amount i head loading unit 5b is searched, and the process moves to step m6. If there is data at step q3, the process moves to step l116.

Referring again to FIG. 5, it is determined in step m6 whether or not data exists, and if there is data, the data is read out in step 7, and the process moves to the display routine of step n1. The registered data is temporarily stored in the buffer 11 and output as a display signal to the display unit 4 to display the registered data.

If there is no data in step l116, that is, if all data has been called, step m8
, it is determined whether or not it is in secret registration mode, and the 37th lag 13c is the theory J! l! rl J, the process moves to step l119, reads the password from the management information area 5c of the data storage section 5, and displays the display buffer 711.
Store in. At this moment, in the step teacher 10, the password display 7 lag 13d is set to logic "1", and the step n
Move to 1. As a result, the entire display section 4 blinks while the password is being displayed, as will be described later.

In step +a8, the 17th lag 13'c is F! ! r
When it is OJ, it is determined that the mode is not secret registration mode, and in step l111, the initial state of telephone mode is restored, and the process moves to step n1.

In this manner, by repeatedly pressing the call key 22 in the calculation mode, the mode is switched to the telephone mode and the call operation is started. Furthermore, when a search is performed in the normal registration mode, the normal registration data is sequentially read out 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 read out from the secret registration head. The data are sequentially read out in the order in which they are stored in the storage 5a, and after all of the secret registration data is read out, the normal registration data is read out, 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, so it is convenient to use.

Furthermore, even if the password is displayed on the display section 4, only a person who knows the password can set the secret registration mode, so there is no worry that the password will be seen by others.

Figure Pt58 is a flowchart showing the specific processing operation of the blinking process in step n4 described above. As described above, when the call key 22 is pressed and the registered data is called by the Komaru, it is displayed on the display section 4 in step n1, the key is read in step n2, and the next call key 22 is not operated. In step n3
Then, the process moves to step s1. In step s1, a counter (not shown) provided in the control unit 9 measures the blinking time.
(Lighting time or 1 + lights out time) 0 to perform counting operation
Next, in step s2, it is determined whether or not the lighting time has elapsed. If the lighting time has not elapsed, the process returns to step n2 and a key reading operation is performed. step s2
When the blinking time has elapsed, the process moves to step s3, where it is determined whether the cursor to be blinked is present. If it does not exist, move to step s5,
It is determined whether the password display flag 13d is logical "1" or not, and if not, the process returns to step n2. If there is no input by the call key 22, the above-mentioned! Following the circular loop, the registered data is continuously displayed on the display section 4.

When registered data is displayed on the display section 4, key 2 is pressed to change the displayed data.
7 is suppressed, the cursor is positioned on the display section 41a of the dot display header 41 of the display section 4. In this situation, 1. Since there is a cursor that should blink in step s3, the alpha extinguishing routine moves from step s3 to step S4 to turn on or off the cursor, and then moves to step n2. In this way, step s1 → step s
A circulation loop of 2 → step n2 → step n3 → step 51 ~ step/bus s4 → step n2 is formed,
This causes the character or number where the cursor is located to blink. When correcting data, a new corrected character is input for each blinking character or number by operating the number key 21 or the like. This moves the cursor to the next digit and causes it to blink.

In this way, (I correction) of the registered data is performed.

! When all the first record data have been recalled, the password is displayed, and in step s5 the password display 7 lag 13d is ``1'', so step s6 is executed.
Then, the entire password displayed on the display section 4 is turned on or off, and the process moves on to step 12. While displaying such a path 7-code, a circular loop of steps 81 to 33 → step s5 → step s6 → step 02 to step n3 → step S1 is formed, and as a result, the path 7-3 displayed on the display section 4 is displayed with α reduced.

In this way, the password is called out and displayed blinking at the end of data calling, so the user can easily recognize the password and can reconfirm the password.

In addition, when modifying a part of the password, a part of the password can be changed by performing the same operation as the normal data modification operation described above in this displayed state. Therefore, the ease of changing passwords is improved, and the user-friendliness is improved.

In the above embodiment, the password is displayed blinking, but other important data may be displayed blinking.

Effects As described above, according to the present invention, only predetermined data is displayed in a flashing manner when g:, H data is called.

This allows important data such as a password to be displayed blinking, making it possible to understand at a glance that it is a password. Therefore, it becomes possible to easily reconfirm and change the password.
