Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cursor (ii) sub-control device 4 in a display gray device.

On an office computer or Word 9 processor, i'
- When inputting evening, display % fi? All 18 r-ta-entry cursors up to the desired input position above.
Punish and specify. Move this cursor within a short range from the current position ((, I use the "Move cursor" key, but this "Move cursor" key moves the cursor one character each time) 1. It is very inconvenient if the cursor is covered in heavy rain over a wide area. For this reason, when moving the cursor around l/, 1jjij, conventionally the b-curse auto-repeat function is used to move the cursor extremely;cqK. To enable this cursor auto-repeat, you must hold down the cursor control key. For this reason, the human power of the data is still t, and the words that need to be corrected are 1.
If the cursor control r111 keys are scattered all over the cursor, or if the object of the ii1'l area specification is ノ(), the time to hold down the directional key of this cursor control r111 key will be longer. Even if the time required to perform the cursor auto-repeat operation is not so shortened and only one cursor auto-repeat function is used, the efficiency is still sufficient.

The present invention has been made in view of the point 1, and it is possible to instantaneously execute cursor movement over a wide range, and to efficiently perform delivery, transportation, etc. at a cursor position 1i'l.
The purpose is to provide a Wll device.

An embodiment of the present invention will be described below with reference to the drawings. 8A
In FIG. 1, 1 is a key γJp-do, which will be described in detail later, but is composed of a tablet and a large keyboard such as a key mat, and is provided with a cursor mode key as well as each insertion key. - Note When a key on the keyboard 1 is operated, a key code corresponding to the operated key is output from the key date control circuit 2 and input to the code conversion circuit 3 and the display address conversion circuit 4. The code conversion circuit 3 converts the key code from the keyboard control circuit 2 into an internal code,
Manually transfer to CPU5.

The CPU 5 processes the internal code input from the code conversion circuit 2, and controls the operations of the code conversion circuit 3 and the display address conversion circuit 4 by outputting all enable signals from the output line 5a. In this case, C.P.

An enable signal is directly input to the display address conversion circuit 4, and an enable signal is input to the enable terminal E of the display address conversion circuit 4 via an inverter 6. In other words, the CPU 5 is always (

The key code corresponding to the predetermined key 711 from the ili'l1Il11 circuit 2 is converted into a key address corresponding to the key position and output to the CPU'5.

This CI'11.5 processes the human data and outputs the updated data to the 1 (indication 7?) and outputs the cursor data to the cursor control circuit 8. ) The input data is sent to the video amplifier circuit IO via the CR'l' controller 9 and displayed on the CRT display section II. It's a trench, the above cursor system (ii

It can display 20 lines of text.

The keep 1 is constructed as shown in FIG. In the figure, numerals 21 to 23 are all character arrangement parts, and keys for kanji, hiragana, katakana, numbers, alphabets, symbols, etc. are provided. In the entire character array section 2.1.22, a part of it as shown by the broken line, that is, 20 lines corresponding to the character display area Ila of the CRT display section 11 shown in FIG. 3; The six columns of key layout areas are set in the cursor designation area 24, and the codes of the keys in this area 24 are set in the display address conversion circuit 4.
I am trying to convert it into a display-address with iL. Further, the keypad 1 is provided with an external character input section 25.1, a lingo input section 26, an idiom input section 27, a function section 28, a numeric keypad section 29, and the like. The upper function section 28 is provided with cursor keys 31 . Scroll key 32, upper fn12 cursor constant area 24 keys as cursor keys -C, +

8 times]) Each 10-\ feed, the CRT display section II shows ``A''. When the cursor mode key 33 is not operated, the keys in the cursor designation area 24 are one key each. Further, when the cursor key 3 is operated, the CPU 5 uses that code to move the cursor by one character in the designated direction.

However, if you want to move the cursor over a wide range,
Operate the cursor mode key 33.

This cursor mode key 33 is operated. Then, a key code corresponding to the VC statement is inputted from the keyboard control circuit 2, which is converted into an internal code by the code changing circuit 3 and sent to the CPU 5. cpU s u When the code for the cursor mode key 33 is manually written, enable No. 18 outputted from the output line 5a is set to "O". For this reason, the code conversion circuit 3 receives the "o" signal to the enable terminal E and enters the nodal operation state, and the display address conversion circuit 4 receives the to 1 r+ times signal to the enable terminal E via the inverter 6 and operates. The situation is "hit". This allows you to specify the cursor area on keyboard 1. '
40q's key p changes the cursor key to i (like a temple). Then, after operating the cursor mode key 33 like I did above, move to the cursor designation area 24, Operate the 1 key corresponding to the desired cursor position - 100. For example, as shown in Figure 3, it is displayed in the 2nd row and 36th column)
Cursor at t C+'klO row 2nd column 6ri hC
If there are more than 1 iihL in 2, then the 2nd L! As shown in 1, specify the cursor at the 10th row, 2nd column [] of the song area 24.ii
"t r'l": Operate the J character key. With this key operation, the keyboard control circuit 2 outputs a code corresponding to the character key [Response], and the display address switching circuit 4 outputs a code to the CRT!; 10 rows 2 columns 1 of the ζ display part
” (3) 21 is removed from the display address that specifies the q-flash. The display address output from the display address conversion circuit 4 is sent to the cursor control fi+11 circuit 8 via the CPU 5. This cursor fli'l ml' circuit 8t records the input display address by 1 and displays it on the CRT controller 9 and video amplifier circuit 10 (+'8 is given and shown on the right of the CRT as shown in FIG. 3; i (II) Move the cursor key 3 to position IK4.C2 in the 10th row and 2nd column of I.On the other hand, when the display address is sent from the display address conversion circuit 4, the CPU 5 then selects the output line 5a.
1" is output as enable No. 18. As a result, the code conversion circuit 3 is in an operating state, the display address conversion circuit 4 is in an inactive state, and the display returns to the initial state of 9. In this way, the display 1iill III You can instantly move the cursor to any position.

In the above example, each key in the cursor designation area 24 corresponds to one character on the display screen, but in other cases, for example, as shown in Figure 4, each key corresponds to a block area on both sides of the display. You may also do so. in this case,
When the cursor is moved by key operation in the cursor designation area 24, the cursor is moved to, for example, the start address of the row or column of the designated block, and within each program, the cursor is moved by operation of the cursor keys 31. With this configuration, the cursor can be quickly moved to any position on the display screen. Incidentally, FIG. 4 shows an example in which an area of 2 rows and 4 columns on both sides of the display is treated as one block and corresponds to one key.

According to the present invention, as shown in /Rpeta, a wide ψ-encompassing cursor movement; KI! + can be quickly executed with a 17ii key operation, and it is possible to provide a cursor position #rllill device that allows editing, editing, etc. to be performed efficiently.
