Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a display control device, and particularly to a display control device that allows scrolling of display data on a display device of an electronic computer to be set to an arbitrary speed by simple specification. It is.

[Opportunity for the Invention] The present invention sets the scroll speed of a display device in seconds using key input, and also sets the screen break unit (type of screen break: for example, one screen, By setting a half-screen (one line, etc.), the set screen is automatically changed at each set time, making it unnecessary to perform a scrolling operation every time.

[Prior Art] Generally, when an operator wants to view desired data on a display device of a computer, it is necessary for the operator to give scrolling instructions one after another until the data to be viewed is displayed on each screen.

[Problems to be Solved by the Invention] Therefore, when a large amount of data is displayed on a display screen, scrolling operations become extremely troublesome.

SUMMARY OF THE INVENTION Therefore, the present invention provides a display control device that can automatically change the screen in set units at set time intervals.

[Means for Solving the Problems] FIG. 1 is a block diagram of the present invention. In the figure, I is the first means of setting the screen scroll speed by key input, and 2 is the unit of screen change (range of screen change) by key input.
3 is a third means for generating display data based on the screen break unit information set by the second means 2 and the speed information set by the first means 1; 4 is a third means for generating display data; This is a fourth means for displaying the content from the third means 3.

[Operation] The operation of the present invention is that the screen scrolling speed is set by the first means (2) by key input, and the screen break unit is set by the second means 2 by key input.

Next, a third means 3 based on the screen break information set by the second means and the speed information set by the first means 1.
generates display data, and performs automatic scrolling in which the contents from the means 3 are displayed by the fourth means, thereby eliminating the need for individual scrolling operations.

[Example] (1) Structure 11 is a key input unit, 12 is a scroll speed buffer, and the scroll speed buffer 12 stores the scroll speed (school start interval) set by the key input 11. A scroll screen unit buffer 13 stores the type of change mode of the scroll screen. 14 is a time counter, 15 is a comparison circuit, and when the contents of the time counter 14 and the contents stored in the scroll speed buffer 12 match, the comparison circuit 15 displays the information from the scroll screen unit buffer 13 to the display buffer 1B in order to start scrolling. Give instructions. Reference numeral 17 denotes an output data storage section consisting of a page buffer and the like. The display buffer IB develops the data sent from the output data storage section into a dot image, and transfers the data to the display section 19 via the display control section 18 by the scroll unit.

(2) Operation FIG. 3 is an automatic scroll setting operation flowchart showing the operation of the above configuration. First, step 81 key input 1
1 sets the screen break speed and unit (range). In the case of automatic scrolling, first set "1m" on the counter CTR.
is set, but in the case of step s8, which is the previous counter CTR-0, normal key input is performed. Since automatic scrolling is performed here, the first step is to press CTR.
-1, so it is determined to be "yes" (Y) in step S2, and since CTR-1 is determined to be "yes" in step S3, the scroll speed for the above screen break is set in the scroll speed buffer 12 in step S4. , step S5
111111 is added to the counter CTR (CTR
-2). In the case of CTR-2, “No 1” is determined in step S3.
(N), the screen break unit is set in the scroll screen unit buffer 13 in step SB, and step S7
The counter is set to CTR-0 and the normal key input mode is entered.

After that, when the time set in the scroll speed buffer 12 comes, a display instruction is issued from the scroll screen unit buffer 13 to the display buffer (dot RAM) 1B, and the display buffer 1B sends the display control unit 18 to change the screen by the scroll unit. The data is transferred and displayed on the display section 19. As a result, the screen is changed by the scroll unit.

Here, the dot RAM of the display buffer 16 has a capacity for two screens, and when one screen has been displayed, data for a new screen is transferred from the output data storage section 17 to the dot RAM.

Figure 4 shows how the above screen break is performed, and Figure (a) shows the case where the screen break range is one screen unit, and in this case, one automatic scroll One screen is completely replaced. FIG. 4(b) shows a case where the screen change range is in units of half a screen, and in this case, the half screen is replaced by one automatic scroll. FIG. 4(C) shows a case where the screen break range is centered on one fold, and in this case, only one line is scrolled in one automatic scroll.

[Effects of the Invention] When displaying a large amount of output data from a computer on a display device, the speed at which information is searched should be determined by the content of the display data. Therefore, as in the present invention, if the screen is automatically scrolled at a speed suitable for the above data content,
The information searcher only needs to look at the screen and does not need to perform scrolling operations one by one.
