Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic computer device equipped with a CRT device, particularly a scroll control device in a display device of a personal computer.〇Prior art Fig. 6 shows a conventional computer device. 1 is a keyboard, 2 is a keyboard data input device for inputting data from the keyboard, and 3 is a block diagram of a scroll control device.
Reference numeral 4 designates a cursor control device that controls the display of a cursor, 4 a screen scroll control device that controls the scrolling operation of the display screen, 6 a CRT, and 6 a keyboard control device.

In the conventional scroll control device configured as described above, when performing a scroll operation, the cursor control key indicating the scroll operation is selected on the keyboard 1 and the key is pressed.When the key is pressed, the keyboard data is input. The key data is input to the device 2, and the keyboard control device 6 analyzes the key data.The keyboard control device 6 analyzes the key data, recognizes the moving direction of the cursor, and uses the cursor control device 3 to display the key data on the CRTS. move the cursor in the specified direction. From the time when the 20:00 cursor reaches the edge of the screen, the keyboard control device 6 uses the screen scroll control device 4 to scroll the screen on the CRTs in the scrolling direction indicated by the pressed cursor control key. This operation continues until the cursor control key on keyboard 1 is released.

Problems to be Solved by the Invention However, with the above configuration, the scrolling direction must first be selected using a key, so it takes time to select the key in the scrolling direction, and the keyboard 1 and keyboard 1 are required to perform the scrolling operation. The problem was that it did not match human senses, such as requiring a lot of movement of the line of sight to and from the CRT6, was slow in processing, and was difficult to use.

In view of these points, the present invention allows selection of the scrolling direction in a method that suits human senses and with fewer movements. It is an object of the present invention to provide a scroll control device that can perform high-speed scroll selection operations by reducing the movement of the line of sight.

Means for Solving the Problems The present invention provides a scroll control device comprising a pointing device data input device, a cursor shape memory device, a cursor position memory device, a comparison device, a pointing device control device, a cursor control device, and a screen scroll control device. It is.

According to the above-described configuration, the present invention displays the state in which scrolling is possible and the scrolling direction during scrolling by changing the shape of the cursor on the display screen, and controls the operation of the cursor, the pointing device, and the switch attached to the pointing device. By combining these, it is possible to determine the direction of scrolling and the start and end of the scrolling motion, and the scrolling motion can be performed in a manner that suits human senses, with fewer motions, and with fewer double-line motions.

Embodiment FIG. 1 shows a configuration diagram of a scroll control device in a first embodiment of the present invention. In FIG. 1, 7 is a pointing device, 8 is a pointing device data input device that inputs data from the pointing device 7, 9 is a CRT device, 10 is a cursor position storage device that stores the cursor position on the CRTQ, and 11 is a cursor. A comparison device 12 compares the position stored in the position storage device 1o and the position of the pointing device 7 obtained from the pointing device data input device 8; 12 is a CRT device 9;
A cursor control device that controls the operation and shape of the upper cursor, 13 a screen scroll control device that scrolls the display screen on the CRT device 9 in a designated direction, and 14 that stores the shape of the cursor on the CRT device e. 15 is a pointing device control device that controls the pointing device data input device 8, the cursor shape memory device 14, the cursor position storage device 10, the comparison device 11, the cursor control device 12, and the screen scroll control device 13. .

The operation of the scroll control device of this embodiment configured as described above will be described below.

First, normal cursor movement processing will be explained using the flowchart of FIG. D. Input position data from P, D, 7 using data input device 8.

17, in the case of normal cursor movement processing, P, D,
7 Branches to 23 because the attached switch is OFF @ At 23, the P, D, control device 15 retrieves the cursor shape from the cursor shape memory device 14 and determines whether it is the normal cursor shape shown in FIG. If the cursor shape is normal, the process branches to 25, and if the cursor shape is different, the process branches to 24.

At 24, the P, D controller 15 uses the cursor controller 12 to return the cursor shape on the CRTQ to the normal cursor shape shown in FIG.

At 26, the P,D controller 15 inputs a cursor position using the P,D data input device 8, and uses the cursor controller 12 to move the cursor display on the CRTs to the input position.

Next, at 26, the P, D, controller 16 stores the current cursor shape using the cursor shape storage device 14, and then stores the current cursor position using the cursor position storage device 10 at 27. 〇 Next, scroll processing will be explained〇 In this example,
To scroll, press P, D, and the attached switch to change the cursor to the shape shown in Figure 4, indicating that scrolling is possible, and then move P, D, and 7 in the direction you want to scroll. The cursor changes to the shape shown in FIG. 5 indicating the scrolling direction, and a scrolling operation is performed.

To stop this scrolling operation, press P, D.

7 Release the attached switch or press P, D, P, D.

7 Return the attached switch to the pressed position.

However, if the switches attached to P, D, and 7 are pressed,
The shape of the cursor as shown in FIG. 4 indicates that it is still in a scrollable state.

The above operation will be explained using the flowchart shown in FIG.

At 16, the P,D,control device 16 inputs the data of P,D,7 using the P,D,data input device 8.

At step 17, the P, D, and control devices 16 check the states of the switches at P, D, and 7, and if a scroll operation is to be performed, the switches are pressed, so the process branches to step 18. At 18, the P, D, and control devices 15 The cursor controller 12 is used to set the cursor shape on the CRTs to the shape shown in FIG. 4, and the cursor shape memory device 14 is used to store the current cursor shape.

At 19, the P, D, control device 15 uses the comparison device 11 to compare the cursor positions of P, D, 7 indicated by the P, D, data input device 8 with the contents stored in the cursor position storage device 1o, If the cursor position changes at 20 2
The process branches to 1, and if there is no change, the process returns to 16.

At 21, the P, D, control device 15 uses the comparison device 11 to input the moving direction of P, D, 7, and considers the moving direction input at 22 as the scrolling direction.
From the cursor shapes shown in the figure, select the cursor that indicates the input scroll direction with a black arrow, and
2 to change the cursor, use the screen scroll control device 13 to scroll the screen on the CRTs in the input scroll direction, use the cursor shape memory device 14 to memorize the current cursor shape, and process 16. Return to

As described above, according to this embodiment, by providing a pointing device data input device, a cursor position storage device, a cursor shape storage device, a comparison device, a cursor control device and a two-screen scroll control device controlled by a pointing device control device, , determines the start, end, and direction of the scrolling operation using the operation of the pointing device and its attached switch and changes in the shape of the cursor on the CRT in a manner that is fast, requires fewer eye movements, fewer movements, and is compatible with human senses. be able to.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, the start and end of a scroll operation and the determination of the direction of scrolling can be performed with fewer operations.
This can be done in a way that requires less eye movement and is more in tune with human senses, and has great practical effects.
