DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the mobile data input device of the present invention.

The movement data input device of the embodiment shown in FIG. 1 is composed of a flat plate-shaped mouse pad 2 and a mouse 1 which moves on the plane.

The mouse 1 outputs the movement amount information when the mouse 1 is moved on the mouse pad 2, and the mouse movement amount information output section 11 which is a permanent mouse, which is known in the art, and the mouse 1 is placed on the mouse pad 2. When there is an alternating magnetic field, mouse pad 2
And a transmission unit 12 that is generated with respect to. Transmitter 1
2 has a transmission coil, for example, and supplies an alternating current to this to generate an alternating magnetic field.

On the other hand, the mouse pad 2 has a receiver 21 for detecting an induced electromotive force due to an alternating magnetic field from the transmitter 12 of the mouse 1 and a position of the mouse 1 on the mouse pad 2 according to the received information. The position information generation unit 22 that calculates the coordinates, which is the position information, and the mouse movement amount information output unit 11 of the mouse 1 supply the mouse movement amount information, and the position information generation unit 22 supplies the mouse position information. Therefore, it has a cursor movement amount information output unit 23 which converts the mouse movement amount information into cursor movement amount information by a conversion coefficient based on the position information of the mouse and outputs the cursor movement amount information. The receiving unit 21 has, for example, a large number of receiving coils, and obtains reception information indicating which receiving coil has the maximum induced electromotive force due to the alternating magnetic field from the transmitting coil.
