Abstract

PURPOSE:To improve efficiency in the case of inputting many identical keys continuously by utilizing both previous and current duration times of depressing of the key and changing an autorepeating interval. CONSTITUTION:When the identical key is kept to be depressed the duration time in which a keyboard 1 capable of key repeating is depressed for a first time is stored in a first storage device 2. Then the duration time in which the identical keyboard 1 is kept to be depressed is stored in a second storage device 3. The functional processing is performed with a processor 4 by using the pervious and current key-repeating duration times stored respectively in the first and the second storage devices 2 and 3 to automatically change an auto-repeating interval. Thus, the auto-repeating loading when a key is depressed next time can be changed and, efficiency can be improved when the identical key is repeatedly inputted in a continuous manner.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device capable of key repeat input by continuously pressing the same key on a keyboard, and a key for varying the auto repeat speed according to the key pressing duration. The present invention relates to a repeat input control method.

[0002]

2. Description of the Related Art If a large amount of the same key input is desired to be continuously performed, repeatedly pressing the key is not efficient in terms of work. Therefore, the auto-repeat function is such that once the key is pressed, the same output result as when the key is repeatedly pressed is obtained according to the key-press duration.

However, the auto repeat function in the conventional key repeat input control system has a constant repeat speed after the repeat input is started, and is inefficient when many identical keys are continuously input. Even when the repeat speed can be changed after the repeat input is started, the operator has to reset it when necessary, which is not efficient.

As a method of varying the auto-repeat speed using the conventional key-repeat input control method, there has been proposed a method of varying the speed from the key depression to the start of auto-repeat input as shown in the flowchart of FIG. FIG. 7 is a flowchart showing a keyboard repeat input control system (key repeat input control system) disclosed in Japanese Patent Laid-Open No. 2-28815.

This routine shown in the flowchart of FIG. 7 is called and executed each time one character is input. And
Change the time from the start of key press to the start of repeat input. In step 30, the backward key and the other keys are distinguished. Cs in step 31 and step 38 is
This is a counter that counts whether the same single key has been input 10 times in succession. In steps 33 to 36 and steps 39 and 40, the input character is output. Then, in steps 37 and 45, in the case of the backward key, the time t from the start of pressing the key to the start of the repeat input is made a little longer, and conversely, in the case other than the backward key, it is made a little shorter. Have been reset.

A conventional auto repeat speed changing device is
It is configured as shown in FIG. 7, and the time t from the start of key depression to the start of auto repeat input is variable.

[0007]

The conventional key repeat input control system is inefficient when a large number of the same keys are continuously input because the specified value of the auto repeat speed from the start of the auto repeat input is fixed. There was a problem. Further, even when changing the specified value, the operator needs to reset the value, which causes a problem of poor work efficiency.

The present invention has been made in order to solve the above-mentioned problems, and can improve efficiency in the case where many identical keys are continuously input, and change the specified value of the auto repeat speed. Even in the case, it is an object of the present invention to provide a key repeat input control method that can improve work efficiency by eliminating the need for the operator to reset the value.

[0009]

In the key repeat input control method according to the invention of claim 1, a first storage device 2 for storing the previous key pressing duration and a current key pressing duration are stored. The second storage device 3 and the first and second
A processing device 4 for processing the key pressing duration stored in the second storage devices 2 and 3 as data.
Is to change the auto-repeat interval by utilizing the key-press durations stored in the first and second storage devices 2 and 3, thereby varying the auto-repeat speed at the next key press.

In the key repeat input control method according to the second aspect of the present invention, the storage device 6 for storing the key pressing start time.
And a processing device 4 for processing the key pressing start time stored in the storage device 6 as data, and the processing device 4 obtains the key pressing continuation time obtained based on the key pressing start time stored in the storage device 6. And the number of repeat input characters per unit time are used to change the auto repeat interval so as to change the auto repeat speed at the next key press.

[0011]

According to the first aspect of the present invention, the auto-repeat speed from the start of auto-repeat input at the next key press is changed by performing the predetermined processing of the previous key-press duration and the current key-press duration.

According to the second aspect of the present invention, the auto-repeat speed from the start of auto-repeat input at the next key press is changed by subjecting the key press duration and the number of repeat input characters per unit time to predetermined processing.
