Abstract

PURPOSE:To improve operability by providing travel amount zero clear circuits which set the amount of travel of a cursor in a Y-axis direction at zero when a horizontal travel button is depressed and that of travel in an X-axis direction at zero when a vertical travel button is depressed in the horizontal and vertical travel of the cursor. CONSTITUTION:The output of an X-axis sensor 11 and a Y-axis sensor 12 are two-phase pulse signals corresponding to the amount of travel in each coordinate direction, and those output are inputted to an X-axis counter 21 and a Y-axis counter 22 in a control part 2, respectively, and hold the amount of travel as count data, respectively. However, zero is set at the Y-axis counter 22 by the travel amount zero clear circuit 23 while the horizontal travel button 13 is depressed, and zero is set at the X-axis counter 21 by the travel amount zero clear circuit 24 while the vertical travel button 14 is depressed. Therefore, it is possible to travel the cursor accurately in the horizontal and vertical directions only by depressing the button even when the travel direction of a mouse is not exactly set in the horizontal or vertical direction. In such a way, the operability can be improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to cursor movement of personal computers, etc.
This invention relates to the improvement of a mouse used as a human-powered dehyss for inking.

[Conventional technology]

There are two types of mice: mechanical,
There are types such as optical type and acoustic type. Furthermore, there are various variations in the number of pointing buttons and the interface method with the connected main device. When these are combined, it can be said that it generally consists of the following components.

(1) X and Y axis movement amount sensor (2) Button switch (3) Data multiplexer (4) Host interface It is decomposed by the multiplexer and sent to the main device through the host interface.

[Problem to be solved by the invention]

When operating a cursor using a mouse, it is difficult to move the mouse accurately horizontally or vertically, even if you try to move the cursor horizontally or vertically. For example,
To draw a straight line horizontally using a graphics processor, it is normal to select the end point position and then make small adjustments while looking at the screen so that the line is horizontal.

Some applications allow you to move the cursor horizontally and vertically by operating the mouse without pressing the Shift 1 key on the keyboard, but this method requires simultaneous operation of the mouse and keyboard. The operability is not good because I can't concentrate. It is also believed that this method is application-dependent or that an application-independent implementation of horizontal and vertical cursor movement is required.

[Means to solve the problem]

The mouse of the present invention is used in workstations and personal computers, and has an X-axis and Y-axis movement detection function for freely moving a cursor on a display screen, and a function for pointing an object on the screen with the cursor. In a mouse that has one or more button switches for operation, there is a horizontal movement button to direct horizontal and vertical movement of the cursor, a vertical movement button, and a button in the X-axis direction when the horizontal movement button is pressed. , a movement amount zero clear circuit that sets Cero as the movement amount in the X-axis direction when the vertical movement button is pressed.

〔Example〕

Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram of a mouse showing one embodiment of the present invention. In this figure, the mouse can be broadly divided into movement sensors,
A sensor unit 1 including switches, etc., a control unit 2 that secures and formats data from the sensor unit, and an interface unit 3 that manages and controls the interface between the host 1 and the system 4 that input mouse data and use it for applications. configured.

The sensor unit 1 includes an X-axis sensor 1 for detecting the amount of mouse movement in the X-axis direction, and a Y-axis sensor 1 for the X-axis direction.
2. Horizontal movement button 13 for instructing horizontal movement of the cursor
．． Similarly, vertical movement button 14 for vertical direction. and switch 15. It is composed of a switch 16. At least the sensor part] must be installed in the mouse body, and the control part 2. The interface unit 3 may be realized as a mouse body or an external circuit.

In general, X-axis sensor]1. The output of the Y-axis sensor] 2 is a two-phase pulse signal corresponding to the amount of movement in each coordinate direction, and these are sent to the X-axis counter 21. The amount of movement is input to the Y-axis counter 22 and held as data in the column 1, respectively. However, while the horizontal movement button ] 3 is pressed, the movement amount zero clear circuit 23 sets the Y-axis counter 22 to ``Cero'' or ``Cero 1'', and while the vertical movement button 14 is pressed, the movement amount zero clear circuit 23 24, zero is set on the X-axis counter 21.

Data of X-axis counter 2] and Y-axis counter 22, that is, the movement amount of each coordinate axis, switch] 5 and switch 1
Each binary data representing 0N10FF from 6 to 6 is input to the multiplexer 25, and is formatted into the 3-hyde data format shown in FIG. 2 as data to be sent to the system 4 from the host 1.

In this example, since each coordinate axis movement amount count data is expressed in 10 bits, the first hide is
Flag SF, two switches ON10 indicating that
Flag SW1.FF indicating the F state. .

In addition to SW2, the top two pitsu1 of each movement amount count data
The second and third bytes are respectively composed of the lower eight bits I of the X-axis and Y-axis count data.

The interface unit 3 sends these data to the host system 4 in a predetermined format. In addition, the X-axis counter 21. The count value of the Y-axis counter 22 is reset in preparation for the next transmission when the data is taken in by the multiplexer 25.

Next, FIG. 3 shows an example of the external shape of a mouse according to the present invention.

The mouse body 31 is usually held with the right hand, and the index finger and middle finger are used to press the switch 32. Use the switch 33.

At that time, place the horizontal movement button 34 in a position where you can operate it with your thumb.
A vertical movement button 35 is arranged. Mouse with cable 3
6 to be connected to the main body.

〔Effect of the invention〕

As described above, the present invention realizes horizontal and vertical movement of the cursor by ignoring the amount of movement in the Y-axis or X-axis direction when the mouse is moved without pressing a button. In other words, even if the mouse movement direction is not exactly horizontal or vertical, as long as the button is pressed, the cursor can be moved accurately horizontally or vertically, which has the effect of improving operability.

Another feature of the present invention is that the method of horizontal and vertical movement of the cursor does not depend on the application, and that it does not affect the interface with the post system.
