Description

DETAILED DESCRIPTION OF THE INVENTION (11) Technical Field of the Invention The present invention relates to a display control method for controlling the display position of a cursor on a display device.

B) Prior art and problems In a display device using a cathode ray tube, there is a usage method in which the display screen is divided into two or more areas, and characters can be input using a keyboard in each of the nine divided screen areas. □As is well known, display devices employ a cursor display method that indicates the position of the next character to be input, but in the above split screen method, the cursor position in each split screen area is changed depending on the input content. It will be different.

Therefore, in a display system that has two screen areas A and B, when entering characters into the tfA screen area and then into the next KB screen area by operating the keyboard, in the conventional system, it is necessary to operate several keys. , the cursor displayed in the large screen area had to be moved to the appropriate position in the 8 screen area (the position where the next character will be input and displayed), which had the disadvantage of making character input operations time-consuming (cl. Purpose of the Invention The present invention has been made to solve the above-mentioned drawbacks.
The purpose of this invention is to provide a display control method that eliminates the need to move a cursor when switching areas on a screen.

(d) Structure of the Invention The present invention provides a display device that has a display section and a keyboard and that indicates the position on the screen of the display section with a cursor, in which the screen of the display section is divided into at least two screen areas. storage means for storing the position of the cursor on each split screen area; and means for specifying the split screen area; When a split screen area other than the first split screen area is specified while the cursor is displayed, the history cursor is displayed at a position determined by the storage means on the specified split screen area. The present invention is also characterized by a display control method, and further includes a display control means for displaying the cursor in all of the split screen areas. The figure is a block diagram illustrating an embodiment of the present invention, in which 1 is a screen, 2 is a display control section, 3 is a character generator, 4 is a mesh, 5.7 is an address selection section, and 6, 8tj Address register, 9 is keyboard, 10, 11. 12 is switching section, 13.14 is digit position counter, 15.16 is line counter, A, B are display characters, C is cursor, D, D person, DB are characters data, E
is a screen switching key, FAsFB is a unit screen, oh character key, Ka, Kb are cursor codes, MA, MBFs memory section, P is a pulse signal, Xa, Xb, Ya, Yb are address data, a, b are cursor positions, el is a switching signal, 4
One port is a contact point. l1w1 in the figure is the unit screen FA
Correspondingly, the display memory 4 is also divided into memory parts M^ and MB. In other words, the character data D (DA
IKm) is displayed on the unit screen FAK, while memory section MB
The character data D (D!I, Kb) read from the unit screen FB is displayed on the unit screen FB. In the embodiment, the cursor C is displayed at cursor position 8 to the right of the character rAJ displayed on the unit screen FAK. . This is displayed by the character data D in the memory section M and the cursor code Ka. Note that the unit screen designation is switched by using the screen switching key EK of the keyboard 9. In addition, the switching unit 1 is returned to the initial state.
0.11 and 12 are on the contact (A) side, and the screen is unit screen F
It is assumed that the system is selected.

In the figure, when both the digit position counter 13 and the line counter 15 are K "0", the cursor code Ka is stored at the beginning (top left corner) of the memory unit M, and therefore the top left corner of the unit screen FA. Cursor C is displayed at 0. In this state, if you operate the character key G on the keyboard 9, the digit position counter 13 will be set to 1 by the pulse signal P (generated every time one character is input) issued from this key G. Since this address data "1" is set in the address register 8, the cursor code Ka is moved to the position to the right of the upper left corner (second character of the first line).

Since the character data D manually entered using the input character key GVc is stored in the upper left corner of the memory ISMA, the character A and the cursor C are displayed on the unit plane F as shown in KH1. In this way, the cursor C is always displayed to the right of the most recently input character, and the position of this cursor is the output Xa from the digit position counter B and the output Ya from the line counter 15.
It is determined by the O value (in other words, address data Xs and Ya). Similarly, the display position of the cursor (C) displayed on the FBK for one unit screen is determined by the cursor code Kb stored in the memory section M, and this cursor code Kb
The address on the memory of is address data xb and Yb
When the keyboard 90 screen switching key E is pressed after entering characters on the O unit screen Fm designated by Since the switching is performed, the memory section MB is selected in the memory 4, and the switching signal C is also supplied to the display control section 2. Therefore, the digit position counter 14
and address data Xb and Yb by the row counter 16
is given to the address register 6.8, the cursor code Kb can be read out and supplied to the display control section 2. This will move the cursor C to the cursor position on the unit screen FII.
is displayed, and the cursor display at cursor position a disappears.

This switching display is performed by a switching signal e given to the display control section 2. Naori - Full code Kb is in memory section M
The location where the character B was stored is the position to the right of the character data DB of the latest input character B on the unit screen F. As is clear from this, in the embodiment having the unit screens FA and FB divided into two, each time the screen switching key E of the keyboard 9 is pressed, the cursor C moves to the next to the right of the most recently input character. Since the cursor C can be displayed at the same position, there is no need to move the cursor C when switching screens for character input.In the embodiment, the cursor on one unit screen was erased each time the unit screen was switched, but when the unit screen The cursor C may be always displayed on both FA and F.

(fl Effects of the Invention As described above, when inputting and displaying characters by switching divided unit screens, the present invention only requires manual movement of the cursor at the time of screen switching, reducing the time required to input characters using the keyboard. This has the advantage of significantly improving operability.
