DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A dice eye reading system according to an embodiment of the present invention will be described with reference to FIGS. In the reading system of the present embodiment, as shown in FIG. 1A, a normal hexahedral dice 10 is used.
Although not shown in the drawing, each surface of 0 has the eyes of "1" to "6". An identification number transmission tag 20 for transmitting an identification number is embedded near the surface of each surface of the dice 10, as shown in FIG. The identification number transmission tag 20 is, for example, US Pat. No. 4,333,07.
The element described in the specification No. 2 is used.

The identification number transmission tag 20 has an identification number reading section 40 which will be described later with an identification number indicating the eyes on the surface opposite to the surface.
Send to. For example, the identification number transmission tag 20 for transmitting the identification number indicating the eye "6" on the opposite surface is embedded in the surface "1". The identification number transmission tag 20 includes
A storage unit 22 for storing the identification number to be transmitted, a conversion unit 24 for converting the identification number stored in the storage unit 22 into an electromagnetic wave signal, and a transmission coil 26 for transmitting the electromagnetic wave signal converted by the conversion unit 24 are provided. Has been. A built-in battery may be provided as a power source for operating the identification number transmission tag 20, but in the present embodiment, the transmission coil 26 is provided with a capacitor 28 and electromagnetic waves from an identification number reading unit 40, which will be described later, are used to transmit the transmission coil 26. The electric power due to the induced electromotive force induced in the capacitor 28 is stored in the capacitor 28 and supplied to the storage means 22 and the conversion means 24.

As shown in FIG. 2, the dice rolling plane 3
Below the 0, a number of receiving coils 32 for receiving the electromagnetic wave signal transmitted from the identification number transmitting tag 20 embedded in the dice 10 are provided. Receiving coil 3
The second surface is a quadrangle having substantially the same size as the dice 10, and the dice rolling plane 30 is covered by, for example, 36 receiving coils 32 of 6 rows and 6 columns, as shown in FIG.

The identification number of the electromagnetic wave signal received by each receiving coil 32 is read by the identification number reading section 40 which will be described later. For example, when five dice 10 are shaken, they are scattered on the dice rolling plane 30 as shown in FIG. 2, and each dice 10 stops on any of the receiving coils 32.

As shown in FIG. 3, a large number of receiving coils 32 are connected to the receiving coil switching means 42 and switched by the identification number reading section 40 so as to be sequentially read. Therefore, the recognition numbers of the plurality of dice 10 can be read by switching the reception coils 32 at high speed by the reception coil switching means 42 and reading the recognition numbers. By assigning different recognition numbers to the plurality of dice 10, it is possible to surely recognize which dice 10 has what number.

The identification number reading section 40 includes a receiving coil 32.
The reception signal converting means 44 for converting the electromagnetic wave signal received by the recognition number into the recognition number, the recognition number judging means 46 for judging the eye of the dice 10 based on the recognition number converted by the reception signal converting means 44, and the recognition number transmission Electromagnetic wave generating means 4 for generating an electromagnetic wave for supplying electric power to the tag 20.
And 8 are provided.

First, the operation of supplying power to the identification number transmission tag 20 embedded in the dice 10 will be described. An electromagnetic wave is generated from the receiving coil 32 by the electromagnetic wave generating means 48 of the identification number reading section 40. Receiving coil 32
The electromagnetic waves generated from the electromagnetic wave generate induced electromotive force in the transmission coil 26 of the identification number transmission tag 20 embedded in the dice 10, and the induced electromotive force generated in the transmission coil 26 accumulates power in the capacitor 28. The power stored in the capacitor 28 is supplied to the storage means 22 and the conversion means 24,
The identification number transmission tag 20 is in the operating state.

Next, the reading operation of the dice 10 will be described. It is assumed that the dice 10 shaken on the dice rolling plane 30 has stopped on a certain receiving coil 32 with a certain surface as the upper surface, as shown in FIG. As described above, the identification number transmission tag 20 is embedded near the six surfaces of the dice 10. Therefore, in the vicinity of the receiving coil 32, the 6
Since there are the individual identification number transmission tags 20, there is a possibility of receiving electromagnetic wave signals from them. However, since the degree of coupling between the receiving coil 32 and the transmitting coil 26 of each identification number transmitting tag 20 is different, the identification number transmitting tag 20 on the bottom surface is
Can receive the identification number.

For example, in the case of FIG. 3, the receiving coil 32
While the signal receiving direction of the transmission coil 26 of the identification number transmission tags 20D and 20B embedded in the side surface of the dice 10 is parallel to the dice rolling plane 30. For this reason,
Identification number transmission tag 2 embedded on the side of the dice 10
The electromagnetic wave signals from the 0D and 20B transmission coils 26 are not received by the reception coil 26. The receiving coil 26 receives only the electromagnetic wave signal from the transmitting coil 26 of the identification number transmitting tags 20A and 20C whose signal transmitting direction is perpendicular to the dice rolling plane 30. Moreover, the identification number transmission tag 2
The transmitting coil 26 of 0A is extremely close to the receiving coil 32, whereas the transmitting coil 26 of the identification number transmitting tag 20C is far from the receiving coil 32. Therefore, the electromagnetic wave signal from the transmission coil 26 of the identification number transmission tag 20A and the electromagnetic wave signal of the transmission coil 26 of the identification number transmission tag 20C have greatly different sensitivities, and the reception coil 32 transmits the identification number on the bottom surface. The identification number of the tag 20 can be selectively received.

As described above, according to this embodiment, the player cannot see the reading method, and the eyes of the dice can be accurately read without disturbing the interest of the game. The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the identification number transmitting unit is the US Pat.
Using the element described in the specification of No. 333,072,
Other elements may be used as long as the identification number can be read without contact by electromagnetic waves or the like.

Further, in the above embodiment, "1" to
Although the dice with the "6" mark are used, the dice with different patterns on each side may be used to read the patterns. Further, although six-sided dice are used in the above embodiment, eight-sided or ten-sided dice may be used.

[0022]

As described above, according to the present invention, storage means for storing the identification number of the dice eyes, and conversion means for converting the identification number of the dice eyes stored in the storage means into an electromagnetic wave signal, Having a transmission coil for transmitting the electromagnetic wave signal converted by the conversion means, a plurality of identification number transmission unit embedded in the vicinity of the surface of each surface of the dice, and provided under the dice rolling plane, the dice rolling plane A receiving coil that receives the electromagnetic wave signal transmitted from the identification number transmitting unit embedded in the face of the facing dice, and stored in the storage unit of the identification number transmitting unit based on the electromagnetic wave signal received by the receiving coil. Since it has an identification number reading unit that reads the identification number of the dice's eyes, the player can not see the reading method and can accurately read the dice's eyes without disturbing the interest of the game.
