Abstract

PURPOSE:To improve the cursor shift efficiency by using the ten keys of high operability also for cursor shift by means of a function key. CONSTITUTION:A function key 2 is provided to a keying input device to use the ten keys 1 for shift of a cursor. When the key 2 is pushed, the logic value ''1'', for example, is outputted and supplied to an AND gate 3. The numeric characters fed by the keys 1 are supplied to the other end of the gate 3. Thus the gate 3 delivers outputs when both keys 2 and 1 are pushed and actuates a cursor shift part 4. While a decoder 5 designates the cursor shift direction according to the numeric characters of the keys 1. Thus even a slant shift of the cursor is possible when necessary.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cursor movement method in a keystroke input device used in a terminal device, and particularly to a cursor movement method in which cursor movement is performed using a numeric keypad.

BACKGROUND OF THE INVENTION Electronic computer systems are widely used, and various terminal devices are used to effectively use the systems. In particular, terminal devices using display devices are used because of their fast processing speed. A key input device is connected to this terminal device as a means for inputting data.

There is a cursor that indicates the display position of characters to be input, and it is necessary to move this cursor.

[Conventional technology]

This cursor movement is treated as a type of function key of conventional keystroke input devices, and therefore, it is arranged adjacent to other function keys. This results in problems such as incorrect keystrokes and poor operability.

[Problem that the invention seeks to solve]

The above-described conventional keystroke input devices have problems such as the risk of erroneous keystrokes and poor operability, and there is a need for a cursor movement system that has good operability and eliminates erroneous keystrokes.

[Means for solving problems]

The present invention provides a cursor movement method with good operability that solves the above problems. The means for this purpose is to use a terminal device consisting of a keystroke input device and a display device, in which a function key is attached to the keystroke input device to operate the numeric keypad as a cursor movement function, and a cursor movement method is adopted in which the numeric keypad is used to input numbers and move the cursor. It will be done.

[Effect]

The numeric keypad of the keystroke input device is set at a position with good operability, and this numeric keypad is also used for moving the cursor.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the cursor movement method of the present invention, FIG. 2 is a flowchart of the invention, and FIG. 3 is a schematic diagram showing keystrokes and cursor movement states. Use the numeric keypad 1 on the key input device. When the function button 2 is pressed, for example, a logical value 01' is outputted and inputted to one side of the AND gate circuit 3. The numbers pressed on the numeric keypad 1 are input to the other end of the AND gate circuit 3.

Therefore, the AND gate circuit 3 outputs when the function key and the numeric keypad 1 are pressed, and the cursor moving unit 4
will be activated.

Keystroke output from the numeric keypad 1 is input to a decoder 5 and a numeric display section 6. Decoding-5 determines the direction from the keystroke position for "5" on the numeric keypad 1, for example, when "3" is pressed, the direction is diagonally downward to the right, when "8" is pressed, the direction is upward, etc.

The direction result is input to the cursor moving unit 4. Therefore, when the function key 2 and the numeric keypad 1 are pressed simultaneously, the cursor moving unit 4 moves the cursor in a predetermined direction.

The operation will be explained with reference to FIG. When a key is pressed, it is detected whether the option key 2 for moving the cursor has been pressed. This is the state (1). Hereafter, the status will be indicated by numbers in parentheses. If it is pressed, it is detected whether the numeric keypad 1 was pressed at the same time e), and the cursor is moved in the output direction of the decoder 5. When the cursor position is at the edge of the display screen (4), the cursor moving unit 4 stops moving the cursor (5). If the option key 2 and the numeric keypad 1 are not pressed at the same time, the numbers generated by pressing the numeric keypad will be displayed as in the conventional case.

FIG. 3 shows the state of cursor movement. When the option key and the number "9" on the numeric keypad are pressed simultaneously, the cursor located on the display section 10 of the terminal device moves in the B direction. However, if the cursor is pressed for a short time, the cursor moves one character, and if the cursor is pressed for a long time, it moves continuously in the B direction, and when the cursor reaches B, it stops moving.

〔Effect of the invention〕

As described above, according to the present invention, an easy-to-operate numeric keypad is used for moving the cursor, and the cursor can also be moved easily in diagonal directions, resulting in efficient cursor movement.
