Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a display screen scroll control system, in particular, a key on a keyboard board, which is configured to output a signal corresponding to the operating pressure, and has a speed corresponding to the operating pressure. This invention relates to a display screen scroll control method for scrolling up/down a display screen.

Conventionally, a sequential search method and an index search method have been employed to display a desired page from a computer-controlled image file on a display screen. However, in the case of the conventional sequential search method (scroll-up-down method), the speed of page turning is predetermined, so there is a problem that it takes too much time to find the desired page. The index search method has the disadvantage that it cannot be used for searches when memory is vague.

It is an object of the present invention to improve the above-mentioned sequential search method so that the speed of page turning can be made variable in accordance with the operating pressure of key operations, thereby enabling so-called quick searching. Therefore, the display screen scroll control method of the present invention includes a display unit having a keyboard and a display device, a file device that stores display information corresponding to the display screen, and a file management device that manages the file device. a data processing device having a program module, and configured to provide a scroll instruction signal for scrolling up and/or scrolling down the display screen on the display device by operating the keyboard. In the display system, the keys for scrolling up and/or scrolling down are configured to operate in at least two steps, and the operation corresponding to any one step detects the operating pressure of the key operation. The pressure signal corresponding to the operating pressure is converted into a digital signal and outputted, and an interval control section is provided to change the interval according to the value of the digital signal, and the above-mentioned file management is performed. The program module is
At least one scroll instruction signal is received in response to any one step of the key operation, and a plurality of scroll instruction signals are received at the intervals corresponding to the operating pressure in response to the other step of the key operation. The file management program module is configured to receive scroll instruction signals, and the file management program module scrolls up and/or scrolls down the display screen based on the scroll instruction signals. This will be explained below with reference to the drawings.

FIG. 1 shows the construction of an embodiment of the present invention, and FIG. 2 shows the construction of an embodiment of a key used in the invention.

1 and 2, 1 is a display unit, 2 is a data processing device, 3 is a file device, 4 is a display device, 5 is a key board, 6 is a screen control unit, and 7 is a file management program module. , 8 is a page selection address register, 9 is a ±1 circuit, 10 is an interval control unit,
11-0, 11-1, . . . are display information for one page, 12 is a page instruction key, 13U is a scroll up key, 13D is a crawl down key, 14 is a push button, and 15 is a predetermined number of buttons (e.g. 1
(16) is a spring, 17 is a pressure detection/AD converter, and 18 is a plurality of scroll instruction signal terminals.

Assuming that an arbitrary page, for example page #P, is displayed and scrolled up, the operator uses the page designation keys 12 to designate the desired #P page. This causes the file management program module 7 to operate, and the module 7 sets address information in the page selection address register 8 to read the #P page. Then, the desired #P page is read out from the file device 3, as is well known in the art, and transferred to the display unit 1.
displayed on the screen.

Next, when the operator operates the scroll up key 13U, the file management program
A scroll up instruction signal is supplied to module 7. Note that this operation will be explained in detail with reference to FIG. In response to the instruction signal, the file management program module 7 causes the ±1 circuit 9 to perform +1 processing. i.e. #(P+1)
The data is read out from the page file device 3 and displayed on the display device 4.

For scroll down, scroll down
Needless to say, the down key 13D is operated.

In the case of the present invention, the scroll up key 13
Keys having a configuration as shown in FIG. 2 are used as U and/or 13D. The key is spring 1
The push button 14 is pushed up by a push button 6. Then, when the pull button 14 is pressed down, the side surface of the push button 14 reaches the scroll instruction contact 15 at the position A shown in the figure.
When touched, for example, only one scroll up instruction signal is supplied to the file management program module 7. Further, when the push button 14 is pressed down with a pressure equal to or higher than a predetermined pressure, the lower surface of the push button 14 is lowered against the spring 16 to a position B in the drawing beyond the position A in the drawing. At this time, the pressure detection/AD converter 17 validates the pressure detection result based on the fact that a pressure higher than a predetermined pressure is applied, converts the pressure into a digital signal corresponding to the pressure, and converts the pressure into a digital signal corresponding to the pressure. It is configured to output to the terminal 18.

Therefore, if the operator wants to scroll up or down by one page, press the 1st key.
Lightly press 3U (or 13D) to connect contact 15.
Only one scroll up (down) signal is emitted from. As a result, the file management program module 7 supplies the display unit 1 with the page that has been advanced by one page. Also, the operator
When the key 13U (or 13D) is pressed deeply to scroll up (down) by a page, the illustrated interval control section 10 will scroll up (down) by n pages at a period proportional to the pressing force. (down) signal. For this reason, the file management program module 7
The file device 3 has a speed corresponding to the cycle.
Display information 11 is read out one after another from the display unit 1 and supplied to the display unit 1. That is, the screen is scrolled up (down) at a speed corresponding to the pressing force.

As described above, according to the present invention, the speed of scrolling up and/or scrolling down can be controlled according to the operator's intention. For this reason, it becomes possible to perform an operation that quickly flips through the vicinity of a given page.
