Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to movement control of a cursor mark that indicates an input position on a display device.

In general, when inputting characters, symbols, etc. by pressing 1 or N on an input display device, a cursor mark indicates the input character position by sequentially moving it according to the input operation number, or the operator can move the cursor mark to an arbitrary position and move the cursor mark to an arbitrary position. The characters, symbols, etc. at the positions indicated by the marks are corrected. In this case, the movement of the cursor mark is controlled using four cursor keys that instruct left, right, up, and down movement directions.

However, operating these four cursor keys in combination is cumbersome, and especially for an inexperienced operator, it is difficult to bring the cursor mark to a desired position.

Therefore, in the present invention, a large group of keys of an input keyboard device included in a display device are used, and these keys are made to correspond to each display position on the display device, and when the cursor movement mode is set, each key group is assigned to each display position of the display device. The cursor mark is directly moved to the display position corresponding to the key by operating the key corresponding to the key.

To explain the present invention in detail below, FIG. 1 shows a block diagram showing the configuration of a character input processing device including an input board and a display device.

Reference numeral 1 denotes a keyboard device, which includes a group of many character input keys and a group of control keys. This includes a mode switching key for switching between character (data) input mode and cursor movement mode.

Reference numeral 2 denotes a control circuit which performs various controls based on input from the keyboard device 1, and in particular performs the operation process 0-9 shown in FIG.

3 is a display buffer that stores character data to be displayed on the display device 5; 4 is a cursor counter that holds the cursor mark position; the output of this cursor counter 4 is supplied to the display device 5, and the cursor mark is placed in the corresponding digit. indicate.

That is, the display device 5 displays, for example, one character as dots in a 24×24 matrix, and has a display screen having a large number of display character positions (digits). The display device 5 is composed of a CRT display device, a liquid crystal display device, or the like. and,
The cursor mark is displayed at the bottom position of each displayed character digit.

Further, when a character or the like is being input, the cursor counter 4 is sequentially counted up by the control circuit 2 in response to the input operation, thereby updating the display position of the cursor mark.

Further, in the cursor movement mode, the count value of the counter 4 is set via the control circuit 2 based on the operation of the cursor keys shown in FIG.

FIG. 2 is a diagram showing the relationship between the display device 5 and the keyboard device 1. A group of keys for inputting various characters on the keyboard device 1 are arranged at least so that they correspond to each display digit position on the display device 5. The number of keys is 21 of the keyboard device 1.
The character keys within the frame indicated by are made to correspond to the display digit positions on the screen of the display device 5. In other words, the A key is at position A on the display screen, and the B key is at position B on the display screen. In the character input mode, it functions as a normal character entry key, and in the cursor movement mode, it functions as a cursor key for specifying and inputting the display position of the cursor mark.

Therefore, as shown in the operation flow of FIG. 3, if the mode setting is character (data) input mode, step Nl
Proceeding as r N2 + N8, each key within the frame 21 of the keyboard device 1 acts as a normal character entry key.

Then, when the character input mode is switched to the cursor movement mode, steps Nl+N2, N4, and N5 are performed. In other words, when you want to move the cursor to a desired position, press the cursor key corresponding to the desired cursor mark display position on the display screen (frame 2
When a key (inside) is operated, the code of that key is input to the control circuit 2 as position information, and the control circuit 2 sets a count value corresponding to the key code in the cursor counter 4. Therefore, a cursor mark is displayed on the display digit of the display screen corresponding to the operation key.

In this way, the present invention utilizes a large group of keys on the input keyboard device provided in the display device, and makes these keys correspond to each display position on the display device, and also allows the characters (data) input mode and cursor movement mode to be set. In this cursor movement mode, by operating a key corresponding to each display position of the display device, the cursor mark is directly moved to the display position corresponding to that key. desired position ff
! The cursor mark can be moved to , and this cursor mark movement operation is simple and extremely convenient.
