Abstract

PURPOSE:To shift easily a cursor to the desired position, by forming switch trains at the upper (lower) and left (right) sides of a display, and then pushing one of switches of each switch train. CONSTITUTION:Switch trains 5 and 6 are provided at the upper (lower) and left (right) sides of a display part 3, and the outputs of trains 5 and 6 are connected to a detecting device 7 in the form of x and y coordinates. The output of the device 7 is fed to a control part 4 and then supplied to a cursor buffer register 9. A cursor C is shifted to i and j with push of a switch xi and yi of trains 5 and 6 respectively. In such a way, the cursor can be shifted easily by means of a ball pen, etc. and without using any special input tool. This improves the operability of a cursor control system.

Description

Detailed Description of the Invention (&) Technical Field of the Invention The present invention relates to a display device in which information input through an input unit such as a keyboard is processed by a control unit and the information is displayed on a display screen. A cursor is displayed on the display screen to facilitate character input. The present invention relates to a highly operable cursor control method that allows easy specification of the cursor position.

(b) Prior Art and Problems In display devices, a method of displaying a cursor on the display screen is widely used in order to facilitate character input from an input section such as a keyboard. A rectangular display, an underline, etc. are used as this cursor9, and the cursor is usually made to blink at a certain period to clearly indicate the position where input is to be made. There is a mechanism K in which the screen moves to the next display position on the right as the screen moves to the next display position.

Conventional cursor control methods include a method using cursor movement keys and a method using direct instruction using a light pen. In the former case, the cursor is moved one digit at a time in the direction of the arrow by pressing a cursor movement key 1 consisting of four keys with arrows as shown in FIG. For example, as shown in Figure 811 (B) K, an underlined cursor C is displayed at the bottom of display position a on the display screen 2 and in the friend state, if the → arrow key is pressed, the cursor C moves to the display position. Therefore, there is a drawback that key operations are complicated until the cursor is moved to the desired position. Also, although it is easy for the operator to specify the cursor position, since a special indicator pen is used, it is necessary to change the light pen if you are using other operating devices (such as a stylus pen, etc.) (e) Purpose of the Invention An object of the present invention is to facilitate the movement of a cursor on a display screen when holding a pen for writing characters in a character display device, etc. It is an object of the present invention to provide a cursor control method with high operability. In a display device that displays information on a display screen, a cursor indicating the position on the display screen where the next information is input is controlled by using several switches at the top or bottom and left or right ends of the display screen, respectively. Further, a position detector for detecting the array position of the switch and a cursor buffer register for storing the coordinate position of the cursor are provided respectively, and one switch at the upper end or the lower end and one switch at the left end or the right end are pressed. , the array position of the push switch is detected by the position detector, and based on the detection signal, the value at the cursor position of the cursor buffer register is read via the front control, and the value is displayed on the display screen. This is achieved by providing a cursor control method characterized by moving the cursor to a certain position. (・) Embodiments of the Invention Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

2.3 are for explaining one embodiment of the cursor control method of the present invention, FIG. 2 is a front view of the display screen of the display device, and FIG. 3 is a control circuit block diagram.

In this regard, the display device is composed of a display section 3, a control section 4, and an input section 10, as in the conventional case.
The information inputted by the controller 4 is processed by the control section 4, and the information is displayed on the screen of the display section 3. The present invention has a switch column 5 for specifying the row (horizontal direction) position at the top and bottom of the screen of the display unit 3, and a switch for specifying the column (vertical direction) position at the left or right end of the display 113. ◎This switch row corresponds to the number of characters that can be displayed in the horizontal and vertical directions on the 30-character display screen.
Xm Xm・・・・・・Xm and Ft Fm
'1m......y.

The switch is composed of m and n switches, respectively.

Also, the position information 11(x
A position detector 7 for detecting the coordinate position (1j) and a cursor buffer register 9 for storing the coordinate position (1j) of the cursor are provided. Note that a character buffer 8 for storing one screen worth of data to be displayed on the display section 3 is conventionally provided.

Regarding the instruction of the cursor position, when moving the cursor C to the position of the 811 matrix character in the gt character row, select the corresponding switch F? ! 1 and the left end (right end) of the display section 3.

Indicating the corresponding switch row y1 in the switch row K moves the cursor C. Now, one switch in the switch row 5! 1. 601 switch rows
? When Fs is pressed, the switch information Xi 71 is detected by the position detector 7, and the detected information (XIFI) enters the cursor buffer register 9 via the control unit 4. The value of this cursor buffer register 9 is transferred to the control unit. 4 is read out and the cursor C on the screen of the display unit 30 is moved to the coordinate position (1j) of the basket of the cursor buffer register 9. As mentioned above, the movement of the cursor C is possible by instructions of the two switches. ], In addition to pressing the switch with your finger, you can also press it with a ballpoint pen. For cursor instructions on interactive display devices without conventional keyboards, such as O input units such as IK real-time handwritten character input devices, even if you have a pen for inserting characters, you do not have to use a special instruction pen as in the past. No need to switch to Ben O
All you have to do is press the switch first, and the operability of specifying the position of cursor C is extremely poor.

Note that the above switches are other than mechanical switches.

The same applies to electrical switches using pressure-sensitive sheets, magnetic switches using Hall effect elements, optical switches using optical sensors, etc. In addition, it is a matter of course to read the coordinate position from the host combination, set the cursor at the coordinate position, and display the information of the host combination in font on the display section.

(f) Effects of the Invention As explained in detail above, the cursor control method of the present invention instructs one switch in each row of switches that designates the position in the row direction and the column direction of the display screen of the display unit. This allows you to move the cursor to any desired position.・Switch instructions can be made with a ballpoint pen, etc. in addition to your finger, making it extremely easy to operate.
