DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic configuration diagram of a system using the present invention. When the key of the keyboard 5 is pressed, the data of the key is decoded by the keyboard controller 3 and transferred to the microprocessor 1 via the system bus a. When the microprocessor 1 receives the data of the key, the microprocessor 1 processes the data based on the key input control program stored in the main memory 2 and sends the processed data to the display controller 4 via the system bus a. Forward.

The display control section 4 includes a screen information memory 43 for storing the position and font of characters to be displayed on the screen, a cursor position register 41 for storing the position where the cursor is displayed, and a displayed cursor. It is composed of a cursor font register 42 for storing the fonts of. The display control unit 4 uses the written data to display the screen information memory 43, the cursor position register 41, and the cursor font register 4
2 is rewritten, the data is transferred to the display 6, and the display 6 displays the screen and the cursor according to the data.

The cursor font key group 51 arranged in the keyboard 5 is a key group different from the conventional cursor key group, and is provided separately from the conventional cursor key group. The cursor font key group 51 includes keys 511 and 51 for designating the input direction as up, down, left and right, respectively.
3, keys 512 and 514. When any one of the cursor font key group 51 is pressed, the input by the keyboard is in the direction designated by the pressed key, and thereafter, every time data such as a character or a symbol is input by the key, it is displayed on the display 6. Displayed cursor 6
1 moves in the specified direction. Further, with respect to the edit keys (<delete> key, <reverse> key, etc. other than <cursor> key), the editing direction is changed according to the designated input direction.

FIG. 2 shows an example of a font for a cursor for making it possible to confirm the designated input direction on the screen. When the cursor font key is pressed, the cursor font corresponding to the key is changed to the cursor font register 4
It is set to 2, and the cursor font is displayed on the display. Each time one of the cursor font keys is pressed, the font for the cursor is changed to a font corresponding to the specified input direction, so that the input person can determine which of the current input directions is specified on the screen. You can check.

FIG. 3 is a schematic processing flow of a key input control program for controlling the keyboard input direction. Now, it is assumed that (x, y) is written in the cursor position register and the cursor 61 is at the coordinate (x, y) on the display 1. Here, when the key of the cursor font key group 51 is pressed, the pressed key is the key 5
If it is 11, the moving amount xs in the x direction is set to 0 and the moving amount ys in the y direction is set to -1, and stored, and the cursor font register 4 is set.
2 writes the font 201 shown in FIG. If the pressed key is the key 513, the movement amount xs in the x direction is 0,
The movement amount ys in the y direction is set and stored at 1, and the font 202 is written in the cursor font register 42. If the pressed key is the key 512, the movement amount xs in the x direction is −
The movement amount ys in the 1 and y directions is set and stored at 0, and the font 204 is written in the cursor font register 42. If the pressed key is the key 514, the movement amount xs in the x direction is set to 1 and the movement amount ys in the y direction is set to 0, and the font 203 is written in the cursor font register 42.

After the above processing is completed by pressing the key of the cursor font key group 51, or when the key of the cursor font key group 51 is not pressed, it is detected whether or not the character key is pressed and the key is pressed. If not, return to the start position. Screen information memory 4 when pressed
Write the font corresponding to the pressed key at the position of the coordinate (x, y) of 3, and then set the coordinate (x, y) to the coordinate (x, y).
+ Xs, y + ys).

Here, if the key 513 for designating the cursor movement direction downward is pressed, the key input control program stores the movement amount xs in the x direction at 0 and the movement amount ys in the y direction at 1, and stores the cursor. The font register 42 is shown in FIG.
The font 202 shown in is written. By rewriting the cursor font register 42, the cursor 61 is displayed in the form of a font 202. After that, for example, it is assumed that the character keys [A], [B], and [C] are sequentially pressed. First, when the [A] key is pressed, the key input control program causes the coordinates (x,
Write the font "A" in y). As a result, "A" is displayed at the coordinate (x, y) where the cursor 61 is displayed.
Is displayed. Further, the movement amount variables xs and ys are added to (x, y) held in the cursor position register 41, and the contents of the cursor position register are updated as (x + 0, y + 1), that is, (x, y + 1). Moves to the lower coordinates (x, y + 1) where "A" is displayed. Then, by pressing [B], “B” is displayed at the coordinates (x, y + 1), the movement amount variable is added to the coordinates (x, y + 1), and the cursor 6
1 moves to coordinates (x, y + 2). Then, by pressing [C], "C" is displayed at the coordinates (x, y + 2), and the cursor 61 moves to the coordinates (x, y + 3).

Further, if the <reverse> key is pressed in this state, (x, y + 3) currently held in the cursor position register 41 is updated to (x, y + 2) obtained by subtracting the movement amount variables xs and ys. , The font written in the coordinates of the screen information memory 43 is erased. In this way, keyboard input can be advanced to the lower side of the cursor 2. Further, by the same processing, by pressing any one of the cursor font key group 51, the input direction can be specified in any of the up, down, left and right directions.

In the above embodiment, the cursor font key group 51 is provided as an independent key group separate from the conventional cursor key group, but without providing the cursor font key group 51, the cursor key and the shift key are pressed simultaneously. May be detected by pressing the cursor font key.
