Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a terminal keyboard, and more particularly to a cursor control method for moving a cursor on a CRT in the [ ] direction.

(2) Conventional technology and problems In conventional terminal keyboards, the cursor position cannot be CR
T - Carriage return key (hereinafter referred to as CR key) for the left end of the same line on the screen Q - Line foot key (lui & L) for moving to the same horizontal position below the line
When you key in a key other than the F key (called the F key) or a special key such as a function key to perform a specific action with one key-in action, the code 1 of that key is displayed at the current cursor position on the CRT screen. 3 - Move the cursor position one position to the right (if the current cursor position is at the right edge of the screen, the left edge of the line below 2) If the cursor position is at the bottom right corner of the screen, move it to the top left corner of the screen.
I try to do lj. In such a system, top to bottom and bottom to top (i.e. vertically).

Or, if you wanted to hit the court from right to left, you had to move the cursor to each cursor position using cursor movement keys each time you keyed in one code.

(3) Object of the Invention The object of the present invention is to provide a cursor pointer that indicates the cursor position on the keyboard in order to eliminate the above-mentioned drawbacks.

The object of the present invention is to control the direction of movement of the cursor after a general court key-in by providing a movement amount pointer indicating the amount of increment of ink and a lock type cursor movement direction key for controlling it.

(4) Structure of the Invention The present invention is capable of inputting the value of the movement amount pointer indicating the value to be added to the cursor pointer indicating the cursor position by keying in any of the four types of lock type cursor movement direction control keys (2), up, down, left and right. This is a cursor control method that changes the cursor movement direction.When a code other than a special code such as the CR key, LF main key, or function key is keyed in after the cursor movement direction is determined, the code transfer circuit transfers the current code behind that code. Adds the value of the movement amount pointer to the cursor pointer as a new cursor position,
It sends the data to the CRT and controls the cursor position.

(5) Examples of the invention Examples of the present invention will be described in detail below.

FIG. 1 shows a general example of the positions to which the cursor can be moved on the CRT display 1. In this case, it is assumed that there is a total of xXy parts, including an X part in the horizontal direction and a y part in the vertical direction.

FIG. 2 shows an embodiment of the present invention in which a cursor movement direction control key for indicating the direction in which the cursor is moved is arranged on the keyboard. In the figure, the part 3 on the keyboard 2 is a lock type cursor movement direction control key according to the present invention.

The enlarged view is shown in Fig. 3. This part has four locking keys for instructing to move the cursor in either the up, down, left, or right directions.

Each key is equipped with a lamp (FIG. 3, 4) consisting of a light emitting diode 1 indicating that the key is locked.

FIG. 4 shows an example of the configuration of a cursor control system according to the present invention. The key code keyed in from the keyboard as shown in FIG. 2 is input to the comparator circuit 5 and CR
key, special codes such as the LF primary key function key, cursor movement codes input from the cursor movement direction control keys (Fig. 2, 3), and other general codes. If a special code is input, the code is sent to the CRT via the special code transfer line 9 and the code transfer circuit 8, and the value of the cursor pointer 7 is transferred to the new cursor position via the line 14. The possible values of this cursor pointer 7 are not shown in FIG. 1, but in the case of a CRT display, they are from ■ to (xXy).

Next, when a cursor movement code is entered from the lock type cursor movement direction control key 3 of the keyboard 12 (Fig. 2), the switches S1 and S2 interlocked via the line 11 are controlled by that code, and the right direction cursor is If it is a moving cord, is it terminal T? and T'w are connected. Similarly, for left, down, and up cursor movement codes, the terminals Tu and 'Ft, ]'D and 11-=
, Tu and T5 are connected.

Then, depending on the coat generated from the coat generation circuit 12, the value of the cursor movement amount pointer 6 is changed to Ichikawa Luko for a rightward coat, -1 for a leftward coat, and 1xG for a downward coat. This,” for a two-way code, −
Cent for each X (however, both are CR in Figure 1)
T display). At the same time, the light-emitting diodes 1-13 indicating the respective directions are emitted, and the lamps on the corresponding keys shown in Fig. 3-4 are emitted.
lru. After the cursor movement amount pointer has been moved to 6 or 7 in the above manner, the general coat is set to key 1"2 (
If input from Figure 2), general code transfer line 10
After transmitting the coat to the CRT via the coat transfer circuit 8, the adder 17 adds the values of the cursor pointer 7 and the cursor movement amount pointer 6 according to the signals from lines 15 and 16, and the result is added to the CRT. By storing the value in the cursor ink 7 and sending the value to (1?T) without indicating the cursor position, the cursor is moved in the direction specified by the lock type cursor movement direction control key 3 (Fig. 2). Expression cursor movement direction control key 3 (
Assuming that the right direction key is on in Figure 2), when a general code is input, the value of the cursor pointer 7 indicating the current cursor position is changed to the value of the cursor movement amount pointer "
+1' is added and the cursor position moves one place to the right on the CRT display in FIG. If the left direction key is on, the cursor ink 7 is set to "'-1" and the cursor position moves to the left by one position. Furthermore, if the down arrow key is on, the cursor pointer 7 will change to “→=
The cursor position moves exactly one line below the current position on the CRT display of FIG.

Similarly, if the up arrow key is on, the cursor moves to 7 or '-x' and the cursor position moves to the position exactly one line up.

As described above, lock type cursor movement direction control key 3
By using , you can move the cursor position in the desired direction after a general code is keyed in.

In addition to the lock type cursor movement direction control key shown in Fig. 2, 3, by increasing the number of keys of this kind and storing arbitrary increments in the register corresponding to the keys, it is possible to move the cursor at any time after inputting a code. can be obtained. According to this horizontal tab.

This allows you to easily create vertical tabs.

(6) Effects of the Invention According to the present invention, after keying in a code from the keyboard, the cursor can be moved in any direction left, right, up, down, etc. Especially when you want to key in a code continuously in the up and down direction, you have to manually move the cursor. This has the effect of not having to move.
