[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mouse, and more particularly, to a mouse capable of increasing the degree of analysis of movement of a mouse on a screen.

[0002]

[Prior art]

 As shown in FIGS. 1 and 6, a conventional mouse 10 has a ball 101, a rotary encoder 102, an optical device 103, and control electronics 104. The rotary encoder 102 has a roller 112 and a disk 122. The disk 122 is provided at one end of the roller 112 so as to vertically cross the roller 112. The other end of the roller is in contact with ball 101. The roller 112 is rotated by the movement of the ball 101, and the disk 122 is also rotated. The optical device 103 has a light emitting unit 113 and a light receiving unit 123, and is connected to the control electronic circuit 104 by an outlet. The light emitting unit 113 and the light receiving unit 123 are provided on both sides of the disk 122, respectively.

When the conventional mouse 10 is used, the disk 122 is moved with the movement of the ball 101. The light source projected from the optical device 113 passes through the slit of the disk 122, is received by the light receiving unit 123, and is sent to the central processing unit of an electronic device (for example, a computer main body) connected to the mouse 10 via the control electronic circuit 104. It is transmitted and the calculation process is performed. Further, the processed signal (moving direction and distance of the cursor on the monitor screen) is output to an output device 14 (for example, a monitor) connected to the electronic device and displayed.

When the light source projected from the light emitting unit 113 is received by the light receiving unit 123, the light receiving unit 123 converts the light source signal into a wave-like analog signal 13 (potential signal). As shown in FIG. 2, the control electronic circuit passes the high potential value of the analog signal 13 through the analog / digital conversion electronic circuit 15 of the electronic device by a predetermined high potential value or low potential value, and outputs the signal before the low potential value. Display (for example, display by digital signal 1 of a computer). Alternatively, the control electronics may display the signal before the high potential value in a different manner (eg, digital signal 0 of a computer) through the low potential value. Therefore, the wavy analog signal 13 is converted into a rectangular digital signal.

[0005] The image display of the monitor is controlled by determining the coordinate positions in the X and Y directions of the screen. When the conventional mouse 10 is used, the cursor display position, the moving distance and the direction on the screen are controlled by the positions compared by the X and Y direction coordinates. Therefore, the cursor is activated on the screen as the mouse 10 moves. Two control units are provided to control the moving distance of the cursor on the mouse screen. One control unit is a pixel where the cursor moves on the screen when the mouse moves a certain distance. The other control unit is the direction in which the cursor is moved on the screen with respect to the movement of the mouse. When the moving speed of the mouse on the screen is changed, the set value of the moving ratio between the mouse and the cursor is changed by the mouse driving program. At this time, the fixed distance of the mouse movement is changed, the pixel moved on the screen corresponding to the cursor is changed, and the required moving distance of the mouse corresponding to the distance moved from one end of the cursor screen to the other is reduced. Is done.

When the direction position of the cursor is controlled, the ball body 101 is moved in the X direction and the Y direction by the two optical devices 13 of the mouse 10. Since there is a predetermined distance between the light emitting unit 113 and the light receiving unit 123 corresponding to each other in the optical device, the light receiving unit 123 sequentially generates wavy signals having a phase difference between the wavy shapes by rotating the disk. I do. As shown in FIG. 2A, in the optical device for detecting the movement in the X direction, the light receiving unit X1 generates a wavy signal. As shown in FIG. 2b, the other light receiving unit X2 generates a wave signal. The wavy signal is converted into a digital signal, and the wavy signal is displayed as shown in FIGS. 3A and 3B, and an azimuth change control table is created according to a numerical relationship between the wavy signals. As shown in FIGS. 4 and 5, the numerical values X1 and X2 corresponding to the left rotation of the ball body 101 in the X direction are (0, 0) → (1, 0) → ( (1,1) → (0,1) → (0,0), etc. Numerical values X1 and X2 corresponding to right rotation of the ball body 101 in the X direction are four sets such as (0,0) → (0,1) → (1,1) → (1,0) → (0,0). Indicates a cyclic change. Therefore, a cyclic change is formed by the movement of the mouse, and there are four chances of detecting a change in the directional position in a pixel range that moves on the screen of the cursor.

By the way, monitors with large pixels and large size are inexpensive and widely used. If a user involved in drafting or precision design creates a high-precision work, using a monitor with a high pixel size and a large size will reduce eye fatigue. Since the monitor needs to move the cursor from one end of the screen to the other end in the work, the user changes the setting value of the moving distance relationship between the mouse and the cursor with the drive program, and from the one end of the cursor screen. The required moving distance of the mouse for moving to the other end is reduced. In other words, when the pixels of the high pixel monitor are twice as large as the pixels of the low pixel monitor, the distance the cursor moves on the high pixel monitor screen by moving the mouse a certain distance will be the screen of the low pixel monitor screen. It is half the distance moved by. If the setting value is changed so that the number of pixels where the cursor moves on the screen doubles for a certain distance of the mouse movement, the movement distance and size of the cursor measured on the screen with high pixel degree are the same. The cursor movement distance measured on a screen with a low pixel degree is the same. When the mouse is repositioned in the circulating direction, there are four chances to detect a change in the directional position in the pixel range moved on a screen where the pixel degree of the cursor is high. As the cursor increases, the cursor is not accurately positioned on the fine drawing on the screen, and the resolution of the mouse movement on the screen decreases.

[0008]

[Problems to be solved by the invention]

 Therefore, an object of the present invention is to provide a mouse capable of improving the resolution of moving a mouse screen.

[0009]

According to the mouse according to the present invention, a light emitting unit, a light receiving unit, and an analog / digital conversion electronic circuit are provided, and when the mouse is moved, the light is projected from the light emitting unit. The light from the two light sources is received by the light receiving unit. The light receiving unit converts the signal from the light source into two string-like analog signals. The analog / digital conversion electronic circuit performs analog / digital conversion on the analog signal according to the predetermined three or more reference values, passes the signal between two adjacent reference values to the analog signal, and generates a kind of signal. It is displayed numerically, converted to a step-like square digital signal, and forms an azimuth change comparison table based on the numerical relationship between square waves. When the numerical value change is circulated once by moving the mouse, the chance of the cursor detecting the azimuth change on the screen is six times or more, so that the resolution of moving the mouse screen increases.

[0010]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, according to the mouse according to the embodiment of the present invention, the light from the two light sources projected from the light emitting unit 113 by the movement of the mouse 2 is received by the light receiving unit 123. The light receiving unit 123 converts the signal from the light source into two string-like analog signals (eg, potential signals) for keeping the phase difference constant, and further converts the analog signals into analog / digital signals as shown in FIGS. 2A and 2B. It is output to the conversion electron circuit 23. The conversion electronic circuit 23 performs analog / digital conversion according to predetermined four reference values of the control electronic circuit 24, and when an analog signal passes between adjacent reference values, it is displayed as a numerical value in a series. The chordal analog signal is converted to a stepped square digital signal, and the numerical relationship between the square waves forms a heading change table.

When the movement of the mouse in the X direction is detected by the light receiving unit 123, one of the light receiving units generates a chord-shaped signal X1 as shown in FIG. 2a and the other light receiving unit as shown in FIG. 2b. The unit generates a chord-like signal X2. The signal X1 and the signal X2 are converted from analog to digital by the predetermined four reference values via the conversion electronic circuit 23 to form a square wave as shown in FIGS. 7a and 7b, and the numerical relationship between the square waves is obtained. Thus, an orientation comparison table is formed. As shown in FIG. 8, the numerical values X1 and X2 corresponding to the left rotation of the ball body 101 in the X direction are (1, 0) → (2, 0) → (3, 1) according to the numerical change rule of the comparison table. → (3,2) → (2,3) → (1,3) → (0,2) → (0,1) etc. Numerical values X1 and X2 corresponding to right rotation of the ball body 101 in the X direction are (0, 1) → (0, 2) → (1, 3) → (2, 3) → (3, 2) → ( Eight sets of cyclic changes such as (3,1) → (2,0) → (1,0). For this reason, when one circular change is completed by moving the mouse, there are eight opportunities to detect a change in the directional position within the pixel range moved on the screen of the cursor.

Therefore, when the monitor is set from low pixel level to high pixel level and the mouse is operated, the setting value of the moving distance relationship between the mouse and the cursor is changed by the driving program, and the position of the cursor on the screen is moved. The required movement distance of the mouse for the movement of the cursor from one end of the screen to the other end is reduced by doubling the number of pixels. When one circular change is completed by moving the mouse, there are eight opportunities to detect a change in directional position in a pixel range moving on a screen where the pixel degree of the cursor is high. Since the number of pixels required to detect a change in the cursor direction on a screen with a high pixel degree and the number of pixels required to detect a change in the cursor direction on a screen with a low pixel degree are the same, the cursor is accurately positioned on a fine drawing of the screen. The degree of analysis that moves on the screen of the mouse is improved.

As shown in FIGS. 7A and 7B, when an analog signal is converted into a square signal by four reference values, the change state in one unit of the numerical values X1 and X2 represented by the square signal is ( (1,0) → (2,0) → (3,1) → (3,1) → (3,2) → (2,3) → (2,3) → (1,3) → (0, 2) → (0,2) → (0,1) → (1,0). For this reason, since the time required to complete the change state within a unit time is different, the cursor is not moved smoothly.

As shown in FIGS. 10A and 10B, according to the mouse according to another embodiment of the present invention, the analog signal received by the light receiving unit 123 shown in FIGS. 2A and 2B is as shown in FIG. The signal is converted into a triangular wave signal via an integrating electronic circuit 21, and the triangular wave signal is output to an analog / digital conversion electronic circuit 23. The conversion electronic circuit 23 performs analog / digital conversion according to predetermined four reference values of the control electronic circuit 24, and displays a kind of numerical value when a signal passes through a signal between two adjacent reference values. It is. As shown in FIGS. 11a and 11b, the analog signal is converted into a step-like digital signal, and as shown in FIG. 12, an azimuth change reference table is formed by the numerical relationship between the square waves. According to the numerical change rule of the comparison table, the change state of the numerical values X1 and X2 displayed by the square signal within one unit time is (2,0) → (2,0) → (3,1) → (3,1) → ( (3,2) → (3,2) → (2,3) → (2,3) → (1,3) → (1,3) → (0,2) → (0,2) → (0, Since 1) → (0,1) → (2,0) → (2,0) and so on, when one circulation change is completed by moving the mouse, the required time in a fixed state is the same.

As shown in FIG. 9, according to the mouse moving device according to another embodiment of the present invention, the control electronic circuit 24 has a setting electronic circuit capable of setting a plurality of different reference values, and the setting electronic circuit has Is connected to a plurality of changeover switches of the changeover electronic circuit 25. Switching the switch causes the control electronics 24 to generate a plurality of different reference values. The analog / digital electronic circuit 23 performs analog / digital conversion on the analog signal according to at least three reference values obtained by the control electronic circuit 24, and passes the analog signal between two adjacent reference values. Then, it is displayed as a kind of numerical value to form an orientation change comparison table. Therefore, when the mouse is moved, the cursor has six or more chances of detecting a change in direction on the screen, and the resolution of moving the mouse screen increases.
