[Effect]

The display device according to the present invention operates as follows.

When a key is pressed from the keyboard section 1, the keyboard control section 2 analyzes this keystroke input. At this time, if the key pressed is the scroll key, the scroll number management section 3 starts counting the number of times the scroll key is pressed, and at the same time monitors the time until the next key press. When the next scroll key is pressed within a predetermined period of time, the scroll number management section 3 adds up the number of times the scroll key is pressed. In addition, if no key is pressed after the above-mentioned certain period of time has passed after pressing the scroll key, or if another key is pressed even within this time, the count of scroll keys should be finished and immediately The screen information management unit 4 is notified of the number of times the scroll key has been pressed up to that point. On the other hand, the screen information management unit 4 selects the screen information whose screen page has been updated by the number of key presses from among the managed screen information based on the notified number of presses of the scroll key, and The information is sent to the screen display section 5. Then, the screen display section 5 displays this screen information on the screen.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 2 and 3.

As shown in Fig. 2, the hardware configuration of this embodiment is a keyboard that has scroll keys such as 1 for the scroll up key to move the image from the bottom to the top, and 2 for the scroll down key to move the image from the top to the bottom. 15, a display section 17 that displays screen information, a screen information management section 11 that manages screen information, an interface section 13 that provides an interface between the screen information management section 11, and a processor section that controls the display device. 12, and a ROM in which a control program executed by this processor unit 12 is stored.
The display unit 14 includes a storage unit 16 that stores display information to be displayed on the display unit 17.

On the other hand, FIG. 3 shows a block diagram of this embodiment, which includes a keyboard section 15 where scroll keys are pressed,
A keyboard control unit 21 analyzes keystroke input from the keyboard unit 15 and notifies the screen information management unit 11 of keystrokes via the interface unit 13; a storage unit 26 that stores screen information; Display control unit 24 that performs control for displaying stored screen information on the screen
and a display section 25 that displays screen information. this,
The display control section 24, the display section 25, and the storage section 26 correspond to the screen display section 5.

Furthermore, the number of consecutive presses of the above scroll key.

It has a scroll number counting section 22 that notifies the screen information management section 11 at - times of interruptions, and a timer section 23 for monitoring the time interval of the scroll key presses. The scroll number counting section 22 and the timer section 23 correspond to the scroll number management section 3.

Next, the operation of this display device, and particularly the operation when the scroll up key Kl (hereinafter simply referred to as "key KIJ") is pressed five times in a row will be explained.

When a key is pressed from the keyboard section 15, the contents of this key are analyzed in the keyboard control section 21. When the key is 1, the scroll count counting section 22 starts counting the number of times the key is pressed. First, the number of times the key is pressed is set to 1, and the timer section 23 is set to monitor the time until the next keystroke. If the next key is pressed with 1 within a preset certain period of time, the number of times the key is pressed is updated and the timer unit 23 is set again. In addition, while the number of keystrokes of 1 is being counted, the notification of keystrokes is suspended.

In this way, when the fifth consecutive key press of 1 is completed, the timer section 23 monitors the next key press with the number of key presses reaching 5. Then, if there is no next keystroke for a certain period of time after the fifth keystroke, the counting of keystrokes is immediately terminated, and the scroll number counting unit 22 notifies the screen information management unit 11 that 1 has been pressed on the key five times. This notification notifies the screen information management section 11 via the interface section 13 of the number of keystrokes of 1 by one interruption.

During this monitoring, if the next key press is not made within a certain period of time, or if a key other than 1 is pressed, the counting of key presses is immediately stopped and the number of scroll key presses up to that point is counted. Be notified.

On the other hand, when the screen information management unit 11 learns from an interrupt from the interface unit 13 that there are 5 key presses, that is, 1 key presses for 5 pages, the screen information management unit 11 displays 5 pages of screen information from among the managed screen information. The screen information scrolled by the minute is selected, and this screen information is sent via the interface section 13 to the storage section 26 managed by the display control section 24 and written there. Then, the display control unit 24 displays this screen information on the display unit 25. Then, screen information scrolled by five pages is displayed on the display section 25.

Therefore, when 1 is pressed 5 times in a row on the key,
- The number of keystrokes is notified with the interrupt, and as a result, screen information scrolled by five pages is displayed on the display unit 25, so the effect is that screen scrolling of multiple pages can be done quickly. There is.

Also, after pressing 1 on the first key, 1 on the key after a certain period of time.
If no key is pressed or another key is pressed, the scroll count counter 22 immediately notifies the screen information management unit 11 that 1 has been pressed once on the key, so this is no different from conventional screen scrolling. Notifications will be sent one keystroke at a time.

In addition, in normal operation, either 1 is pressed on the scroll up key or 2 is pressed on the scroll down key, but for example, while 1 is pressed on the scroll up key continuously, 2 is pressed on the scroll down key. sometimes,
Possible methods include ending the count of 1 on the scroll up key, or subtracting the number of consecutive keystrokes of 1 on the scroll up key.

〔Effect of the invention〕

As explained above, in the present invention, when the scroll key is pressed an arbitrary number of times consecutively at intervals within a predetermined period of time, the number of presses is stored in the screen information management unit 4 at the end of the continuous keystrokes. Since the keyboard control unit 2 is equipped with a scroll count management unit 3 for notification, when the scroll key is pressed continuously, the screen can be scrolled for a plurality of pages with one notification, so that the screen can be scrolled quickly.
