  Hereinafter, an operation of the coordinate input device including the mouse pad 1 and the mouse 2 configured as described above will be described.

  FIG. 3 is a diagram for explaining the operation when the mouse 2 is operated on the mouse pad 1 shown in FIG.

  As shown in FIG. 3A, the mouse pad 1 shown in FIG. 1 is placed on a desk or the like so that the protective sheet 40a is on the upper surface, so that the mouse 2 moves on the protective sheet 40a side. It becomes.

  When the mouse pad 1 shown in FIG. 1 is placed on a desk or the like so that the protective sheet 40a is on the upper surface, the solar cell unit 10 embedded in the sponge 43 is exposed on the protective sheet 40a side. In the protective sheet 40a, the region facing the solar cell unit 10 is the transparent part 41. Therefore, when light such as sunlight is irradiated, this light becomes the moving surface of the mouse 2 on the protective sheet 40a. Light is received by the solar cell portion 10 through the transparent portion 41.

  In the solar cell unit 10, when light is received through the transparent portion 41 of the protective sheet 40 a, power is generated by the received light, and power generated by the power generation is supplied to the secondary battery 31. Then, the electric power supplied to the secondary battery 31 is stored in the secondary battery 31. Accordingly, the secondary battery 31 is charged only by placing the mouse pad 1 on a desk or the like so that the protective sheet 40a is on the upper surface.

  The electric power stored in the secondary battery 31 is supplied to the transmission coil 21 via the power transmission circuit 22, and a current corresponding to the electric power supplied to the transmission coil 21 flows through the transmission coil 21. Then, a magnetic field is generated in the direction emitted from the core portion of the transmission coil 21, that is, in the direction toward the moving surface of the mouse 2 and in the opposite direction.

  In this state, the mouse 2 shown in FIG. 2 is placed on the mouse pad so that the protrusion 54 of the protrusion 52 is positioned between the two protrusions 44a and 44b of the mouse pad 1, as shown in FIG. 1 is operated by moving on the mouse pad 1.

  Since the transmission coil 21 that generates a magnetic field as described above is disposed between the two protrusions 44a and 44b, the protrusion 52 provided with the transmission coil 61 is located between the two protrusions 44a and 44b. When the protruding portion 52 of the mouse 2 faces the transmission coil 21, the magnetic field generated by the current flowing through the transmission coil 21 penetrates the core portion of the transmission coil 61 of the mouse 2, thereby causing the transmission coil 61 of the mouse 2 to Even current flows. As a result, the power stored in the secondary battery 31 is transmitted by the transmission coil 21 of the mouse pad 1 in the direction toward the upper surface of the mouse pad 1, that is, the moving surface of the mouse 2, and the transmitted power is transmitted to the mouse 2. The transmission coil 61 receives power without contact.

  At this time, if the desk or the like on which the mouse pad 1 is placed is made of metal, or if a metal is interposed between the mouse pad 1 and the desk or the like on which the mouse pad 1 is placed, As described above, the generation of a magnetic field is prevented. Therefore, it is also conceivable to insert a magnetic sheet on the protective sheet 40b side of the transmission coil 21 of the mouse pad 1.

  The electric power generated by the current flowing through the transmission coil 61 of the mouse 2 is supplied to the secondary battery 81 via the power receiving circuit 62, and the secondary battery 81 is charged. Then, the power stored in the secondary battery 81 is supplied to the press detection unit 51, the rotation detection unit 71, and the wireless data transmission unit 82, and the mouse 2 operates.

  Here, the operation of the protrusions 44 a and 44 b provided on the mouse pad 1 and the protrusion 54 provided on the protrusion 52 of the mouse 2 will be described.

  When the mouse 2 shown in FIG. 2 is placed on the mouse pad 1 so that the protrusion 54 of the protrusion 52 is positioned between the two protrusions 44a and 44b of the mouse pad 1, the protrusion 54 of the mouse 2 is Since the mouse pad 1 has a height sufficient to contact the side portions of the protrusions 44a and 44b of the mouse pad 1, when the mouse 2 is moved, the protrusion 54 is located on the side of the protrusions 44a and 44b of the mouse pad 1. The moving area is regulated by contacting the part.

  Specifically, when the mouse 2 is moved on the mouse pad 1 in the direction of arrow A in FIG. 3A, the protrusion 54 of the mouse 2 is moved to the mouse pad 54 as shown in FIG. The mouse 2 cannot be moved further in the direction of arrow A in FIG. In this state, the transmission coil 21 of the mouse pad 1 and the transmission coil 61 of the mouse 2 face each other, but the length of the protrusion 52 of the mouse 2 is the distance between the two protrusions 44a and 44b in the mouse pad 1. Therefore, the transmission coil 21 disposed between the two protrusions 44 a and 44 b does not face the mouse main body 51. Therefore, even when the hand 3 is placed on the mouse main body 51 and the mouse 2 is operated, the hand 3 does not exist in the region where power is transmitted from the transmission coil 21. The human body is not adversely affected by the transmitted power.

  When the mouse 2 is moved on the mouse pad 1 in the direction of arrow B in FIG. 3A, the protrusion 54 of the mouse 2 becomes the protrusion of the mouse pad 54 as shown in FIG. The mouse 2 abuts on the side of 44b and cannot move any more in the direction of arrow B in FIG. In this state, the transmission coil 21 of the mouse pad 1 and the transmission coil 61 of the mouse 2 do not face each other, and the transmission coil 21 arranged between the two protrusions 44a and 44b faces the mouse main body 51. There is no. Therefore, even when the hand 3 is placed on the mouse main body 51 and the mouse 2 is operated, the hand 3 does not exist in the region where power is transmitted from the transmission coil 21. The human body is not adversely affected by the transmitted power.

  Thus, in this embodiment, the transmission coil 61 for receiving the power transmitted from the mouse pad 1 is provided in the protruding portion 52 protruding from the mouse main body portion 51, and is provided in the protruding portion 52. The projecting portion 54 and the projecting portion 44a provided in the region where the transmission coil 21 for transmitting the electric power of the mouse pad 1 is arranged, so that the movement region of the mouse 2 on the mouse pad is Since it is regulated so as not to face the mouse main body 51, even when the hand 3 is placed on the mouse main body 51 and the mouse 2 is operated, the hand 3 is in the region where power is transmitted from the transmission coil 21. Therefore, power can be supplied from the mouse pad 1 to the mouse 2 in a non-contact manner while operating the mouse 2 without adversely affecting the human body.

  In the present embodiment, the mouse pad 1 having the solar cell unit 10 and generating power in the solar cell unit 10 has been described as an example. However, the mouse pad constituting the present invention is a solar cell unit. It is not limited to the one that generates electric power at 10, but may be one that is connected to an external power source such as a commercial power source and transmits electric power supplied from this external power source. However, in the case where power is generated by the solar cell unit 10, power can be obtained without connecting the mouse pad 1 to an external power source such as a commercial power source, thereby restricting the work area using the mouse 2. Can be loosened.

  In the present embodiment, the mouse 2 having the protrusion 52 having the same length as the distance between the two protrusions 44a and 44b in the mouse pad 1 has been described as an example. However, the length of the protrusion 52 is the mouse. If the distance between the two projections 44a and 44b in the pad 1 is equal to or greater than the distance, the movement area of the mouse 2 on the mouse pad 1 is restricted so that the transmission coil 21 does not face the mouse body 51 as described above. be able to.

  In this embodiment, in addition to the protrusion 44 a for restricting the movement area of the mouse 2 on the mouse pad 1 to the mouse pad 1 so that the transmission coil 21 does not face the mouse main body 51, A protrusion 44b is provided in parallel with the protrusion 44a. This protrusion 44b increases the distance between the transmission coil 21 provided on the mouse pad 1 and the transmission coil 61 provided on the mouse 2 more than necessary. This is not necessary for the purpose of restricting the movement area of the mouse 2 on the mouse pad 1 so that the transmission coil 21 does not face the mouse main body 51.

  Further, the mouse constituting the coordinate input device of the present invention is not limited to the one having the configuration shown in FIG. 2, but for example, the trackball 70 is rotated so as to specify the coordinates on the computer. A variety of devices can be used as long as they can receive the power transmitted from the mouse pad 1, such as those that optically specify the coordinates instead of detecting them.
