(Patent document 2).

Japanese Patent Laid-Open No. 9-53908 JP-A-2005-230306

  However, in the dice device of the type in which the electromagnetic wave absorber disclosed in Patent Document 1 is built in a regular polyhedron, the base is indispensable, and the output can only be determined on the base, which makes the device large. I was sorry. In addition, in the dice apparatus of the type incorporating the acceleration sensor disclosed in Patent Document 2 as another method, since a button battery or the like is used in the power supply unit, power may not be supplied due to battery consumption. There was an inconvenience when using it at a game center or an amusement park that has been in operation for 24 hours.

  Accordingly, it is an object of the present invention to provide a regular polyhedral posture display device that can display a posture position at a remote location without being concerned about power supply, being small and easy to use.

  In order to solve the above-described problems, in the present invention, the regular polyhedron having a plurality of faces is designated in advance by wireless communication and detecting an output from an acceleration sensor that detects posture position information such as inclination and acceleration state. The surface that appears at the position to be displayed is displayed remotely.

  Further, the regular polyhedron can constitute a wireless communication network, and when a plurality of regular polyhedrons are used, the surfaces appearing at predetermined positions in the plurality of regular polyhedrons are collectively displayed on a remote display.

  Further, the regular polyhedron has a structure in which a triaxial acceleration sensor is incorporated, a solar cell is disposed as a power generation element on the entire surface of the regular polyhedron, an electric double layer capacitor is disposed as a power conversion element, and a lithium ion battery is disposed as a storage element. By doing so, it has a self-supporting power source that is operated by a light source such as natural light or illumination light.

  According to the present invention, for example, in a hexahedron-shaped dice device used in a game center or an amusement park, a triaxial acceleration sensor that is a sensor for detecting posture position information such as the inclination and acceleration state of the dice and the sensor It is possible to transmit / receive the position information of the dice from each other by wireless communication, and it is possible to construct a wireless communication network between a plurality of dice devices.

  Further, a sensor for detecting the attitude position information of the dice, a CPU section for performing analog signal processing on the attitude position information of the dice from the sensor and performing A / D conversion, and digital data signals from the CPU section are wirelessly transmitted to the remote display By including a wireless unit to transmit, the sensor, the CPU unit, and a power supply unit that supplies power for driving the wireless unit, it is possible to display the posture position information of the dice at a location away from the dice.

  The sensor is a three-axis acceleration sensor using a semiconductor MEMS process, and the power supply unit includes a power generation block, a power conversion block, a power storage block, and a stabilized power supply block, and the power generation block includes a solar cell, The power conversion block has an electric double layer capacitor, the storage block has a lithium ion battery, and the stabilized power supply block has a DC-DC converter, so that a self-supporting power source that operates by external light can be configured, and no battery replacement is required. become.

  In this way, it is possible to reduce the size of the power supply unit by using a charging method in which the generated energy of the solar cell is temporarily converted by the electric double layer capacitor, and in this connection, the entire device can be reduced in size. .

  Further, since a wireless communication network can be constructed, when a game with a plurality of game players is performed, each player can use one dice device, and the game progresses smoothly and the fun of the game increases.

  Furthermore, the regular polyhedron posture display device of the present invention does not require a base that is required for a type incorporating a conventional wave absorber, and therefore can be easily provided in a facility such as a game center or an amusement park. .

  Furthermore, in the case of a type with a built-in acceleration sensor, since the battery is used as the power supply unit, the battery may be consumed during the game, and the game may have to be interrupted. Since the solar cell is arranged on the outer surface of the game, the game interruption due to the power supply does not occur in the environment such as most game centers and amusement parks where a light source can be secured.

  As described above, according to the present invention, it is possible to construct a dice apparatus that can operate a plurality of simultaneously by constructing a wireless communication network, to configure a small dice apparatus that does not require a base, and to A dice apparatus that does not need to worry about the life of the apparatus due to wear becomes possible.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an external appearance of a regular polyhedral dice or a toy similar to the regular polyhedral posture display apparatus according to the present invention. As shown in the figure, the regular polyhedron includes a regular tetrahedron, a regular hexahedron, a regular octahedron, a regular dodecahedron, and a regular icosahedron. However, a general polyhedron shape can be used in a toy having a different use from the dice.

  FIG. 2 is a block diagram showing an acceleration sensor, a CPU section, a power supply section, and wireless communication means in the regular polyhedral posture display apparatus according to the embodiment of the present invention.

  FIG. 3 is a block diagram showing an outline of a power supply unit according to the regular polyhedral posture display apparatus of the present invention.

  As shown in FIG. 2, the remote display type dice device as a regular polyhedral posture display device according to an embodiment of the present invention includes an acceleration sensor 1, a CPU unit 2, a wireless unit 3, and a power supply unit 4. . The acceleration sensor 1 detects the inclination and acceleration state of the dice. The CPU unit 2 performs A / D conversion by subjecting the inclination and acceleration signals from the acceleration sensor 1 to analog signal processing. The wireless unit 3 wirelessly transmits the digital data signal from the CPU unit 2 to the other via the antenna 5. Further, the power supply unit 4 has a function of supplying power for driving the acceleration sensor 1, the CPU unit 2, and the wireless unit 3.

  Further, the power supply unit of the regular polyhedral posture display device of the present invention has a private power generation block, a power conversion block, a power storage block, and a stabilized power supply block, and as shown in FIG. The power conversion block includes an electric double layer capacitor 7, the power storage block includes a lithium ion battery 9 which is a high energy density secondary battery, and the stabilized power supply block includes a DC-DC converter 10. Reference numeral 8 denotes a charge control circuit.

  Here, when using a solar cell for the remote display type dice device, the solar cell has a high output impedance during power generation, so the secondary battery cannot be charged efficiently, and a large area solar cell panel is required for charging. It is difficult to reduce the overall size. Further, when the surface of the remote display type dice device on which the solar battery is installed is the bottom surface, the secondary battery cannot be charged and the lithium ion battery 9 installed in the storage block during use at the game center or amusement park 9 There was a possibility that the operation would stop due to the discharge.

  Therefore, in the embodiment of the present invention, an electric double layer capacitor 7 having a low impedance is inserted between the solar cell panel 6 and the lithium ion battery 9. At this time, since the electric double layer capacitor has a low impedance, it can efficiently store the electricity generated by the solar cell panel. As for the flow of charging, the electricity generated by the solar cell panel is stored once in the electric double layer capacitor and the lithium ion battery is charged, but since it can be charged efficiently, the area of the solar cell panel can be reduced, A dice device that can be miniaturized and is equipped with a self-supporting power source can be realized.

  Furthermore, in the embodiment of the present invention, by arranging the solar cell panels on all six surfaces of the dice, it is possible to stably generate power with the solar cell panel regardless of which surface of the dice comes to the bottom surface. In addition, a wireless communication network can be configured, and when a plurality of communication networks are used, a plurality of items can be collectively displayed on the remote display.

  The detection of the die of the dice device is performed by acceleration vector analysis of a triaxial acceleration sensor. For example, when detecting the outcome of a regular hexahedral dice device, the first eye is the front surface, the sixth eye is the bottom surface, the second eye is the front surface, the fifth eye is the back surface, the third eye is the right side surface, and the fourth eye is the left side surface. In this case, the three-axis acceleration sensor is fixedly arranged in the dice so that the first and sixth eyes are arranged on the Z-axis, the second and fifth eyes are arranged on the Y-axis, and the third and fourth eyes are arranged on the X-axis. When determining the outcome, if only the Z-axis of the 3-axis acceleration sensor has a positive voltage value with respect to the default voltage value, it is determined to be the first eye. Further, if only the Z-axis of the three-axis acceleration sensor has a negative voltage value with respect to the default voltage value, it is determined as the sixth eye. In the same manner, it can be determined that the eyes of 2, 3, 4, 5, and 5 are output based on the outputs of the X and Y axes of the triaxial acceleration sensor.

  As described above, in the regular hexahedron, the output is determined by the amount of change in the output voltage value of one of the XYZ axes, but in the other dihedral shape of the regular polyhedron, one axis, two axes, or three axes of the XYZ axis The output is determined based on the amount of change in the output voltage value, that is, the vector composite value of the output voltage values on the XYZ axes.

  FIG. 4 is a perspective view illustrating the inside of the regular hexahedral dice apparatus according to an embodiment of the present invention. As shown in FIG. 4, the outer dimensions are a width dimension a of 30 mm, a depth dimension b of 30 mm, and a height dimension c of 30 mm (30 × 30 × 30 mm cube). In addition, the A substrate 21 (first substrate), the B substrate 22 (second substrate), the C substrate 23 (third substrate), and the sensor mounting substrate 24 (fourth substrate) are arranged from the top. They are assembled in order through the support. The substrate assembled in this way is configured to cover all six surfaces with solar cell panels (FIG. 4 shows only the solar cell panel 20 on the upper surface). The power supply unit 28 includes an A substrate 21, a B substrate 22, and a C substrate 23. The A substrate 21 is a power conversion substrate on which the electric double layer capacitor 25 is mounted. The B substrate 22 is a substrate that controls charging. The C substrate 23 is a substrate for output, and is mounted with a lithium ion battery 26 and a DC-DC converter. An acceleration sensor, a CPU unit, and a wireless unit are mounted on the sensor mounting substrate 24 at the bottom. An antenna 27 is provided on the back surface of the sensor mounting board 24 on which the acceleration sensor and the like are mounted. The solar cell panel and each substrate have a width of a little less than 30 mm, a depth of a little less than 30 mm, a height of 2 mm, and a flat plate shape.

  Specifically, a transmitter / receiver 30 that is used in a game center or an amusement park and that enables wireless communication is connected to a display 31 that displays a dice roll and a game screen. The dice device 29 transmits posture position information of each dice to the transceiver 30 by wireless communication, and the information is displayed on the display 31. Since it has a function capable of constructing a wireless communication network, it is possible to display information of a plurality of dice devices 29 remotely and collectively.
