Description

Ball mouse cursor speed control

The present invention relates to a ball mouse cursor speed control device, and more particularly, a ball mouse cursor that can change the movement speed of a cursor in multiple steps by an operator's operation in a ball mouse that moves a cursor on a monitor screen. It relates to a speed regulator.

Generally, in the computer, a keyboard for inputting a signal by pressing a plurality of keys has been used as a means for inputting a predetermined signal. At present, as computers are used in various fields, it is difficult to input signals to the computer using only the keyboard.

For example, when playing a 3D game using a computer or performing a CAD (Computer Aided Design; CAD) operation, input of a signal is not appropriate using the keyboard alone. That is, the operator performs a signal input operation for processing this image while watching the displayed screen. In this case, the operator repeatedly performs a simple indentation operation, but the keyboard is not suitable for such an operation.

To meet this need, a signal input device called a mouse has recently been developed.

1 is a perspective view schematically showing a mechanism inside a conventional ball mouse.

Mice are classified into mechanical mice and optical mice according to the method of detecting coordinates.

As shown in FIG. 1, the dual mechanical mouse has a ball 16 that can be rotated forward, backward, left, and right on the inner bottom surface of the case 11. The drive shaft 12 of the X and Y axes which are in contact with the outer circumferential surface of the ball 16 is orthogonal to the friction shaft 13 which rotates as the ball 16 rotates in the X-axis direction, and the ball 16 is Y-axis. The friction wheel 13 that rotates as it rotates in the direction is installed in contact with the ball 16. One end of the drive shaft 12 connected to the friction wheel 13 is provided with a rotating disk 14 is equipped with a plurality of slits. Photocouplers 15 having light emitting diodes and light receiving diodes are provided on both sides of the rotating disc 14, respectively. Accordingly, the rotary disk 14 and the photocoupler 15 having a plurality of slits radially perform an encoder function.

When the operator holds the case 11 of the mechanical mouse configured as described above by hand and moves it to the front, rear, left and right directions, the ball 16 rotates in the X and Y axis directions according to the movement of the case 11. The rotational force of the ball 16 is transmitted to the friction difference 13 in contact with the ball 16 so that the rotation disc 14 rotates. Each of the rotating disks 14 is radially mounted with a plurality of slits. When the rotating disk 14 rotates, the photocoupler 15 mounted on the side thereof detects the rotation of the slits and changes the period according to the rotational speed. It will output a pulse signal with. Thereafter, the microprocessor of the computer counts the number of pulses in the photocouplers 15 on the X-axis and the Y-axis to move by a relative displacement at the current cursor position.

However, since the number of pulses of the photocoupler 15 according to the moving distance of the ball 16 is constant in the conventional ball mouse 10 as described above, the movement speed of the cursor is too fast depending on the type of program such as a game or a word processor. Or too slow.

For example, when the game program is executed, the movement speed of the cursor is relatively slow. If there is no function to improve the speed of the cursor in software, it causes inconvenience.

Therefore, the present invention is an input device of a computer, a ball mouse cursor that maintains the movement speed of the cursor in accordance with the currently executed program by changing the movement speed of the cursor in multiple steps by the operator's operation in the ball mouse for moving the cursor on the monitor screen It is to provide a speed regulator.

In accordance with the forward and backward movement of the adjusting knob 26a, the curved pulley 26 is pivoted within a predetermined rotation angle range.

In addition, the curved pulley 26 has a semicircular curved surface having the same center as the center of rotation of the ball 16.

EXAMPLE

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

Figure 2 is a side view showing the external state of the ball mouse according to the present invention.

The present invention is provided with a ball 16 that can be rotated front, rear, left and right on the inner bottom surface of the case 21, each friction difference 13 is in contact with orthogonal to the outer peripheral surface of the ball 16, One end of the drive shaft 12 to which the friction difference 13 is fixed is applied to the ball mouse 20 in which the rotation disc 24 is installed.

Except that the square groove 21a is formed on the side of the case 21, it has the same structure as the conventional case 11 (FIG. 1), since the square groove 21a has many people using the right hand. It is preferable to form on the left side.

3 is a perspective view illustrating an arrangement state of a speed regulating mechanism in FIG. 2.

According to the present invention, the support 25 for rotatably supporting the drive shaft 12 on which the friction difference 13 and the rotating disc 24 are mounted is formed to have a predetermined curvature and is slidably moved by the guide 27. It is joined to the curved pulley 26 supported.

The support 25 is formed in at least two places as shown, but if it is too large, the operation is not smooth. The drive shaft 12, the friction difference 13, the rotating disc 24 and the like act as a movable part integrally with the curved pulley 26.

This curved pulley 26 has a semicircular curved surface having the same center as the center of rotation of the ball 16.

In this way, the drive shaft 12, the friction difference 13, the rotation disc 24 and the like pivot about the ball 16 with the curved pulley 26, but the contact state between the friction difference 13 and the ball 16 Can be maintained.

In addition, the rotating disc 24 according to the present invention is formed with a plurality of slits 24a, 24b, 24c on the circumferences of concentric circles of different diameters in the same size and in the same quantity.

Since the conventional rotating disc 14 has a slit of one quantity, there was only a constant proportional relationship between the rotation angle of the friction difference 13 and the number of pulses counted by the photocoupler 15, but the rotating disc of the present invention ( Since 24 has three kinds of slits 24a, 24b and 24c in different quantities, the number of pulses counted by the photocoupler 15 for the same rotational angle of the friction difference 13 appears in three forms. .

For example, in the illustration, each of the slits 24a, 24b, 24c is eight, four while the friction difference 13 is rotated by a predetermined angle, that is, while the user drags the ball mouse 20 by a certain distance. It can be seen that the relative positional movement of the cursor can be changed by twice depending on which slit 24a, 24b, 24c the photocoupler 15 counts the number of pulses.

Accordingly, the present invention simultaneously fits any one of the three slits 24a, 24b, 24c of the pair of rotating discs 24 to a pair of photocouplers 15 fixed on the case 21. The focus is on the mechanisms that can be used.

2 and 3, a square groove 21a is formed at one side of the case 21, and the adjustment knob 26a is formed near the center of the curved pulley 26 in the square groove 21a. ) Is mounted to protrude so that the curved pulley 26 is pivoted within a predetermined rotation angle range in accordance with the forward and backward movement of the adjustment knob 26a.

Around the square groove 21a on the side of the case 21, high (high speed), medium (middle speed) and low (low speed) are displayed (see FIG. 2), and the adjusting knob 26a protruding into the square groove 21a is shown. Change to any one of them.

When the adjusting knob 26a is placed at the high speed position, the curved pulley 26 is rotated clockwise, so that the photocoupler 15 relatively moves in the outer circumferential direction of the rotating disc 24 to emit light from the outer slit 24a. And light. In this slit 24a, since the number of pulses is counted compared with other slits 24b and 24c, the cursor moves at high speed. When the adjusting knob 26a is placed at the low speed position, the curved pulley 26 is rotated counterclockwise, so that the photocoupler 15 moves relatively in the center direction of the rotation disk 24 to the inner slit 24c. As a result, the cursor moves at a low speed as opposed to the above case.

On the other hand, the present invention has been described with respect to the ball mouse 20 to move the cursor at three kinds of speed, it can be seen that the cursor can be moved at various speeds by varying the type of the slit of the rotary disk 24 have.

As described above, the ball mouse cursor speed adjusting device of the present invention is an input device of a computer, and by improving the encoder part in the ball mouse for moving the cursor on the monitor screen, the cursor moving speed is changed in multiple steps according to the operator's operation. There is an effect that can maintain the movement speed of the cursor for the program being executed.

While the invention has been shown and described with reference to certain preferred embodiments, it will be appreciated that the invention can be modified and modified in various ways without departing from the spirit or scope of the invention as set forth in the claims below. One of ordinary skill in the art will readily know.
