Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a scroll speed control method on a character information display device on a computer system.

[Conventional technology]

Conventionally, in this type of scrolling speed control method, the scrolling speed cannot be increased or decreased depending on the user's convenience while the screen is scrolling, and the scrolling speed is scrolled at a constant speed.

[Problem that the invention seeks to solve]

In the conventional scrolling speed control method described above, the scrolling speed on the display is constant and cannot be changed as needed, so it takes time to reach the desired point, and it is also possible to slow down the scrolling speed to see the desired point. The drawback is that they pass by at a constant speed, making it impossible to see them slowly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a scrolling speed control method that eliminates the above-mentioned drawbacks and allows scrolling on a display at a speed intended by the user.

[Means for solving problems]

The scroll speed control method of the present invention has an input means for inputting a command to increase or decrease the scroll speed from an input device such as a keyboard or a mouse, and whether the command from the input means increases or decreases the scroll speed. a command determining means for determining whether to decrease or decrease; a speed increasing means and a speed decreasing means for increasing and decreasing the through roll speed according to the determination result of the command determining means; and speed increasing means and speed decreasing means for these speed increasing means and speed decreasing means. Scroll control means for controlling scrolling based on the scroll speed changed by.

Example] Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram mainly showing the flow of operation of an embodiment for realizing the scroll speed control method of the present invention, in which input means 11 judgment means 2. Speed increasing means 3. Speed decreasing means 4. Scroll control means 5. It is composed of a display 6.

Referring to FIG. 2, the speed increasing means 3 has a delay (de
The speed reducing means 4 is composed of a delay increasing section.

Next, the operation of this embodiment will be explained with reference to the drawings.

First, the user inputs a command to either increase or decrease the scrolling speed from the current speed using the input means by pressing a function key or clicking the mouse.

Then, the determining means 2 determines whether this command increases the scrolling speed more or decreases it more. If the input command increases the scrolling speed, the speed increasing means 3
If the scroll speed is to be reduced, the speed reduction means 4 is activated.

When the speed increasing means 3 is activated, a delay (de
The delay section 21 reduces the delay part in the program that controls scrolling, and when the speed reduction means 4 is activated, the delay increase section 31 reduces the delay part in the program. The scrolling speed is changed by increasing the delay section.The scroll control means 5 controls the scrolling at the speed changed by the speed increasing means 3 and the speed decreasing means 4, and controls the screen on the display 6. is scrolled at the speed desired by the user.

〔Effect of the invention〕

As explained above, the present invention enables the user to change the scrolling speed by multiple inputs of function keys or multiple clicks of the mouse. This has the effect of reducing the time it takes to reach the desired location, and allowing the user to view the screen more slowly by reducing the speed near the desired location.

[Brief explanation of the drawing]

FIG. 1 is an overall configuration diagram mainly showing the flow of operation of an embodiment of the scroll speed control method of the present invention, FIG. 2 is a diagram showing the configuration of the speed increasing means 3 in FIG. 1, and FIG.
