DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are a front view and a plan view, respectively, showing a mouse system according to the present invention, with a part thereof cut away. In FIG. 1, reference numeral 1 denotes a mouse case, on which a ball 2 is rotatably mounted. The mouse case 1 is provided with a mouse-side coil 3 for outputting code data of a movement data output signal of a movement distance and a movement direction of the mouse case according to the rotation of the ball 2.

On the other hand, reference numeral 4 denotes a mouse pad on which the mouse case 1 is placed and on which the ball 2 is rolled so as to be movable. The mouse pad 4 has a rubber plate 5 having a predetermined thickness and is wound around the rubber plate 5. The pad-side coil 6 includes a magnetic plate 7 having a shape and a size substantially equal to those of the mouse pad 4 and provided so that a peripheral upper surface is in contact with the pad-side coil 6.

Here, the pad-side coil 6 is provided so as to be sandwiched between the peripheral portion of the rubber plate 5 and the peripheral portion of the magnetic plate 7 to protect the coil.

FIG. 3 is a block diagram showing a system configuration of a cordless mouse system according to the present invention. In FIG. 3, reference numerals 1 and 2 denote the above-mentioned mouse case and ball, respectively. A digitizing unit 11 is provided as a multi-directional detection device, which fetches data of the moving distance and the moving direction of the mouse case 1 according to the rotation of the ball 2 and quantifies the data (data coding).

Reference numeral 12 denotes a serial conversion unit provided in the mouse case 1 for serially converting numerically converted X and Y code data and outputting the converted data. The mouse-side coil described above. Here, the digitizing unit 11 and the serial conversion unit 12 constitute a moving data output unit P.

The mouse pad 4 on which the mouse case 1 is mounted is provided with a pad-side coil 6 in a configuration as shown in FIG. An input / output interface 13 is connected to the pad-side coil 6 to enable input / output of the serial data to / from the computer main body 15 via a cable 14. Note that 16
Is a display.

In the mouse system having such a configuration, when the mouse case 1 is moved while rolling the ball 2 on the mouse pad 4, the moving distance and the moving direction of the mouse case 1 are changed to X and Y in accordance with the rotation of the ball 2. And further digitized by the digitizing unit 11 and output.

The digitized X and Y code data is serially converted by the serial converter 12 and output to the mouse coil 6. At this time, by pressing a mouse button (not shown), items can be selected on the screen and a command can be selected. Code data corresponding to these items is converted to serial data and output to the mouse coil 6. Is done.

The code data obtained by the mouse-side coil 6 is electromagnetically induced by the pad-side coil 6 provided on the mouse pad 4 and then input to the computer main body 15 via the input / output interface 13 and the cable 14. .
The code data sent to the computer main body 15 in this manner is data on how far the camera has moved from the current position.
The cursor is moved according to the moving direction and distance based on the data of the cursor position displayed by. That is, the position on the screen can be specified. Although the operation using the magnetic plate 7 is not described in the above description, the magnetic coupling between the pad-side coil 6 and the mouse-side coil 3 can be achieved by providing the magnetic plate 7 as shown in FIG. Can be further enhanced, thus enabling highly sensitive electromagnetic induction of data beyond the degree of coupling with an external magnetic flux. As a result, disturbance of the external magnetic flux can be avoided.

The magnetic flux generated by the mouse-side coil 3 passes through the pad-side coil 6 arranged on the outer periphery of the mouse pad 4 regardless of the position of the mouse case 1 on the mouse pad 4. The electromotive force generated in the pad-side coil 6 is substantially equal at any position, and accurately conveys the position and direction of the mouse case 1.

In the present invention, the mouse coil 3
In addition, since the pad-side coils 6 are close to each other to increase the degree of electromagnetic coupling and can use the minimum energy, it is possible to prevent the occurrence of an induction failure between the pad-side coils 6 of adjacent mouse pads. It can be avoided.

Furthermore, as described above, by eliminating the cable between the mouse case 1 and the mouse pad 4, a mouse system can be established with a simple circuit and at low cost without greatly increasing the number of circuit components and other components used. Practical.
