Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse generalized as a man-machine interface, and more particularly to improving the dustproof property of the mouse.

[0002]

2. Description of the Related Art A conventional mouse is difficult to use in a dusty environment because its movable parts and internal structure are not completely shielded from the outside.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to realize a dust-proof mouse system that can be used even in an environment with a lot of dust and the like.

[0004]

In the dustproof mouse system of the present invention, the mouse body does not have a displacement detecting function to eliminate a mechanism portion and an opening portion through which dust enters, and the mouse body is placed on the upper surface. It is a rectangular flat plate that can be placed on the mouse and moved, and the pressure points are detected from the pressure operation of the pressure protrusions arranged on the bottom surface of the mouse body, and the center points of these pressure points are determined. Calculate the displacement of the mouse body from the mouse body, or move the mouse body on the flat plate on which the conductors are laid in a lattice shape by incorporating a permanent magnet with the magnetic pole direction perpendicular to the bottom surface of the mouse body. By combining the tablet with any function that calculates the displacement of the mouse body based on the current flowing in each conducting wire, and each mouse body that conforms to the function of each tablet It made me.

[0005]

In the dustproof mouse system of the present invention, since the mouse body does not have a movable mechanism for detecting displacement, it is possible to easily form a dustproof structure. Also, the tablet can be easily made to have a dustproof structure by applying the touch panel technology using a conductive thin film or the like.

[0006]

The present invention will be described in detail below with reference to the embodiments shown in the drawings.

1 (a) and 1 (b) show a dustproof mouse system according to an embodiment of the present invention. As shown in FIG.
The configuration consists of a mouse body 1 and a tablet 2. Place the mouse body 1 on the bottom so that it occupies the top of the rectangle.
Two projections 4 for pressurizing are provided, and two dust-proof click buttons 3 are arranged on the upper surface.

The tablet 2 is in the shape of a rectangular flat plate on which the mouse body 1 can be placed and moved, and inside the tablet 2, as shown in FIG.
The pressure point detection unit 21 for detecting the position of each pressure point, and the center point derivation unit for obtaining the center point of each pressure point based on the signal indicating the position of each pressure point from the pressure point detection unit 21. 22, a displacement detection unit 23 that receives the output from the center point derivation unit 22 and calculates the displacement of the mouse body 1 from the change, the output from the displacement detection unit 23, and the input from the mouse body 1 via the connection cord 5. Each unit of the data sending unit 24 processes a signal indicating the click status of the click button 3 in accordance with the transmission format and transmits the processed signal to the computer via the transmission code 6.

In the dustproof mouse system of one embodiment of the present invention constructed as described above, when the mouse main body 1 placed on the upper surface of the tablet 2 is gently pressed, the tablet protrusions 4 make the tablet upper surface 4 square. Pressure is applied at the apex position. The positions of these four pressure points are the pressure point detection unit 2
1 is detected and a signal indicating the position of each pressurizing point is output. Upon receiving this signal, the center point derivation unit 22 calculates the center point of each pressurizing point, and the position of the mouse body 1 is obtained. The signal indicating the center point is sent to the displacement detector 23 and stored therein.

When the mouse body 1 is moved while being pressed, the center point obtained as described above changes, and the displacement detection unit 23 stores the stored center point value and the newly input center point value. The displacement of the mouse body 1 is calculated from moment to moment and output. The signal indicating this displacement and the signal indicating the click state of the click button 3 input from the mouse body 1 via the connection cord 5 are processed by the data transmission unit 24 and transmitted to the computer via the transmission cord 6.

In the dustproof mouse system according to the embodiment of the present invention, since the mouse body 1 does not have the displacement detecting mechanism, the only movable part is the click button 3, and the dustproof type button can be used easily. It can have a dustproof structure.

The tablet 2 can also have a dustproof structure by applying the touch panel technology using a conductive thin film or the like.

This makes it possible to provide a dustproof mouse system which can be used even in a dusty environment.

In the embodiment shown in FIGS. 1 (a) and 1 (b),
The four pressurizing projections 4 of the mouse body 1 are arranged so as to occupy the vertex positions of the quadrangle, but the present invention is not limited to this.
Three points may be arranged so as to occupy the positions of the vertices of an equilateral triangle in consideration of the stability of the mouse body 1 and the amount of calculation for obtaining the center point.

Next, a dustproof mouse system according to another embodiment of the present invention will be described. As shown in FIGS. 2 (a) and 2 (b), in this embodiment, the position of the mouse body is detected by magnetism.

As shown in FIG. 2A, the mouse body 10

Are arranged.

As shown in FIG. 2B, the tablet 20
Reference numeral 1 is a rectangular flat plate shape on which the mouse body 101 can be placed and moved. The conductor wires 202 are laid on the top surface in a grid pattern, and each conductor wire is moved in accordance with the movement of the mouse body 101 on the upper surface. A displacement detection unit that calculates the displacement of the mouse body 101 based on the flowing current, an output from the displacement detection unit, and a signal indicating the click status of the click button 3 input from the mouse body 101 via the connection cord are processed according to the transmission method. Each part of the data transmission part that transmits to the computer through the connection cable is built in.

In the dustproof mouse system of another embodiment of the present invention constructed as described above, the tablet 20
When the mouse body 101 placed on the upper surface of 1 is moved, a current corresponding to the movement flows on each conductor wire 202. Based on this current, the displacement detector calculates and outputs the displacement of the mouse body 101. A signal indicating this displacement and the mouse body 101
A signal indicating the click status of the click button 3 input from the device via the connection code is processed by the data transmission unit and transmitted to the computer via the transmission code.

In the dustproof mouse system according to another embodiment of the present invention, the mouse body 101 and the tablet 201 can be easily provided with the dustproof structure as in the embodiment shown in FIGS. 1 (a) and 1 (b). It can also be used in a dusty environment.
