2. Related Art
Conventionally, various table games are well known and, for example, among table games, there exists a game genre of so-called dice games, as disclosed in WO 07/016,776, U.S. Patent Application Publication No. 2007/0026947, and U.S. Pat. No. 5,413,351.
Among dice games, for example, as disclosed in U.S. Pat. No. 5,413,351, a game method is disclosed in which, upon a player placing a bet, a dealer throws dice and, in a case where a result thereof becomes a predetermined combination, the player is entitled to throw the dice, and has a chance to win a payout of a large amount. In addition, Sic Bo is known as an old and familiar dice game in Asia in which a player places a bet on predicted numbers of dots appearing on three thrown dice.
Sic Bo is well known as a dice game of ancient China, and is a dice game in which a player places a bet on predicted numbers of dots or a combination thereof appearing on three thrown dice. With such a dice game, a result of the bet is judged based on numbers of dots on dice, which come to rest after a plurality of dice are thrown.
In a case of a dice game performed by a plurality of players, a result of the bet can be judged by participants visually confirming the numbers of dots on the dice thrown. However, as the size of a game increases and thus the number of participants increases, it becomes difficult for each participant to visually confirm the number of dots on dice.
Meanwhile, when providing a game by virtualizing dice in a dice game and executing the game on a network or a computer, it may degrade a live aspect in which dice roll and come to rest or rendered effects for chances, rather than a game played by actually throwing dice.
On the other hand, in a case of actually throwing dice and showing that dice roll, it is necessary to read a number of dots on dice steadily, quickly, accurately, and constantly. In a case in which the number of dots on dice can not be read accurately, it may affect advancement of a game. It may also reduce the motivation of a player toward a game if a situation in which the number of dots on dice can not be accurately read continues. Therefore, it is necessary to avoid the situation in which the number of dots on dice can not be accurately read.
Thus, it is an object of the present invention to provide a detection device that can detect a number of dots on dice accurately in a gaming machine that provides a dice game in which dice are actually thrown.
Furthermore, in a case of performing a game by actually throwing a die in a dice game, it is necessary to roll the die. More specifically, in a SIC BO game, a plurality of dice is caused to roll, and as a result of which a bet result that has been placed on is judged. Therefore, causing the dice to roll itself is an important rendered effect of the game. In order to make die rolling be visually recognizable to multiple players, it is necessary to show movement of the die in as large a scale as possible to be recognizable by the players, for example, such as to show the die bouncing many times. Accordingly, in a case of causing the die to roll by oscillating a field supporting the die, it is necessary to move the field itself enough to be visually recognizable to the players. In such a situation, however, there rises a problem in that it tends to cause deterioration and damage to a member connecting between a moving part and a detection device main body due to the motion of the moving part.
Thus, it is an object of the present invention to provide a detection device that can prevent deterioration and damage due to the moving part motion and can detect a number of dots on a die accurately in a gaming machine that provides a dice game in which the die is actually thrown.
According to a first aspect of the present invention, a detection device, which is used in a gaming machine that detects a number of dots on a die, that reads the number of dots on the die, the device comprising: a wireless tag that is disposed in the die; and a reader that reads number of dots information from the wireless tag, wherein the reader includes a plurality of antenna portions that is disposed on a field on which the die rolls, and forms a plurality of detection areas, and wherein the plurality of the antenna portions is disposed so that the detection areas formed by each of the plurality of antenna portions are partially mutually superimposed.
According to a second aspect of the present invention, a detection device, which is used in a gaming machine that detects a number of dots on a die having a wireless tag, and reads the number of dots on the die, includes: a field that supports the die; and a reader that reads number of dots information of the dice from the wireless tag, in which the reader includes: a reader main body portion that decodes the number of dots information from the wireless tag and controls the reader; a first antenna portion disposed substantially in a central portion of the field, and formed in a substantially circular shape; a plurality of second antenna portions disposed so as to superimpose a detection area of the first antenna portion, and having a detection area larger than the first antenna portion; and wiring that respectively connects the first antenna portion and the second antenna portion to the reader main body portion, and in which the plurality of the second antenna portions are disposed so as to have a portion of detection areas mutually superimposed.
According to the second aspect of the present invention, the detection device according to the present invention is used in a gaming machine that detects a number of dots on a die having a wireless tag, and reads the number of dots on the die, and has a first antenna portion disposed substantially in a central portion of the field, and formed in a substantially circular shape and a plurality of second antenna portions disposed so as to superimpose a detection area of the first antenna portion, and having a detection area larger than the first antenna portion. The first antenna portion and the second antenna portion are respectively connected to the reader main body portion, and the plurality of the second antenna portions are disposed so as to have a portion of detection areas mutually superimposed.
Thus, on the field, the first antenna portion and the plurality of the second antenna portions are disposed so as to have a portion of detection areas mutually superimposed. Therefore, the wireless tags on the dice can be detected even if the dice are located at the center or a peripheral portion of the field.
According to a third aspect of the present invention, along with the detection device according to the second aspect, the plurality of the second antenna portions are formed so as to substantially depict a cross shape, and to have a width of each end portion thereof formed so as to be larger than a width of a central portion of the second antenna portion.

Thus, since three antenna portions along with the first antenna portion are provided, the entire field can be detected. Furthermore, areas of side portions of the second antenna portions are disposed so as to be mutually superimposed. Since the antenna line becomes the limiting line of a communication area, it becomes difficult to detect the wireless tag. However, since the areas of the second antenna portions are disposed so as to be mutually superimposed, the two antenna lines are not disposed on an identical line. Therefore, even in a case in which a die comes to rest on one antenna line of the second antenna, the wireless tag of the die can be detected by the other second antenna.

Dice Movable Unit
A dice movable unit 4 is described with reference to
The dice movable unit 4 is configured so as to allow a plurality of the dice 40 to roll and stop. This dice movable unit 4 includes a shaking device 41 that is configured so as to allow the dice 40 to roll, a cover member 42 that covers an upper side of the shaking device 41 and is formed in a dome shape, and a unit main body 43 that houses the shaking device 41. In the present embodiment, the shaking device 41 rolls the three dice 40 (the die 40a, the die 40b, and the die 40c).
The cover member 42 is disposed so as to cover the overall top face of the playing board 41a. Furthermore, the cover member 42 is made of a transparent member in a substantially hemispherical shape and limits an area in which the dice 40 roll.
A plurality of the dice 40 is disposed at a space formed by the playing board 41a and the cover member 42. In the present embodiment, the dice 40 are hexahedral and the IC tags are embedded in each face thereof. It should be noted that this wireless IC tag 401 is embedded in the surface of the dice 40 so as not to be visually recognized from the outside of the dice 40. For example, the dice 40 can be formed by disposing the wireless IC tag 401 at the surface of a member as a base of the dice 40 and then placing a member as a cover thereover. Details thereof are described later.
The dice movable unit 4 includes lamps 44. The lamps 44 perform various rendered effects by emitting lights while the dice 40 are being rolled.
The shaking device 41 is formed in a substantially circular shape as viewed in a plane, supports a plurality of the dice 40, and includes the playing board 41a as a field in which a plurality of the dice 40 are rolled and a cylinder portion 45 that oscillates the playing board 41 vertically (see
Since the playing board 41a is formed to be substantially planar, as shown in
Furthermore, the playing board 41a includes a playing board main body 411, a cushion member 412 that is disposed on the surface of the playing board main body 411, an antenna base portion 413 that is disposed at a lower face side of the playing board main body 411 and in which the antennas 63a, 63b, and 63c are disposed. It is preferable that members forming these are made of a non-metallic member. Since radio waves are susceptible to the interference of metal, if metal exists near the wireless IC tag 401, the communication range between the reader 62 and the wireless IC tag 401 is reduced, and thus it may prevent the wireless IC tag 401 from being read by the reader 62.
Then, wires 64a, 64b, and 64c are connected from the antennas 63a, 63b, and 63c, which are disposed at the antenna base portion 413, to the reader 62. Since these wires 64a, 64b, and 64c are caused to move as the playing board 41a moves along with vertical movement of the cylinder portion 45, the sizes of these wires are formed to be at least longer than the width of the vertical movement of the cylinder portion 45. In addition, the wires 64a, 64b, and 64c are connected to the reader 62 via the cylinder portion 45.
This detection device 61 is mainly configured with the reader 62 that reads information stored in the wireless IC tags 401 which are disposed on each of the faces of the dice 40. The reader 62 includes a control circuit that can be connected to a higher-level device such as a PC and a plurality of loop-shaped antennas 63 that are disposed on the playing board 41a as a field in which a plurality of dice 40 rolls. In addition, the reader 62 is connected with the controller 2.
The reader 62 reads information stored in the wireless IC tag 401, and decodes and transmits the information thus read to the controller 2. In the present embodiment, communication between the reader 62 and the wireless IC tag 401 is performed by way of electromagnetic induction. That is, the reader 62 flows current to the antenna 63 based on an instruction signal from the controller 2 and transmits a predetermined command to the wireless IC tag 401. Then, a magnetic field is altered within the area surrounded by the loop-shaped antenna 63 in which the current flew. Along with the alteration of magnetic flux in this magnetic field, electromotive force is generated within the loop antenna that is included in the wireless IC tag 401 which is disposed within the area. Herewith, electric power is transmitted to the wireless IC tag 401, whereby communication with the wireless IC tag 401 is performed.
In the present embodiment, three antennas 63 of the reader 62 are provided and disposed so that at least a portion of each of the detection areas thereof is mutually superimposed (see
Furthermore, the antennas 63b and 63c as second antenna portions are formed so that four areas of substantially triangular shape depict a cross shape around an apex thereof, and bottom portions of substantially triangular shape are formed with a curve so as to follow the circumference of the playing board 41a. Thus, the antennas 63b and 63c are formed so that the width of the edges thereof is larger at the outer side than the center portion of the playing board 41a. Then, the antennas 63b and 63c are disposed so that the areas of substantially triangular shape thereof are disposed alternately and portions of the areas of substantially triangular shape are disposed to be mutually superimposed. More specifically, a lateral portion of the area of substantially triangular shape of an antenna is disposed so as to be superimposed with a portion of the area of substantially triangular shape of another antenna. Thus, the antennas 63b and 63c are loop antennas formed in a loop-shape so as to be the abovementioned shape.
In the present embodiment, each of the wireless IC tags 401 disposed on a plurality of the dice 40 is read by a single reader 62. Under the abovementioned RFID system, an anti-collision function can be employed which can read a plurality of wireless IC tags by a single reader. For the anti-collision function, there are FIFO (first in first out) type, multi-access type, and selective type, which communicate with a plurality of the wireless IC tags sequentially. FIFO type is a mode to communicate with a plurality of the wireless IC tags sequentially in the order in which each wireless IC tag enters an area in which an antenna can communicate therewith. Multi-access type is a mode that is able to communicate with all the wireless IC tags, even if there is a plurality of the wireless IC tags simultaneously in the area in which an antenna can communicate with the wireless IC tags. Selective type is a mode that is able to communicate with a specific wireless IC tag among a plurality of the wireless IC tags in the area in which an antenna can communicate therewith. By employing the abovementioned modes, it is possible to read a plurality of the wireless IC tags with a single reader.
The wireless IC tag 401 is configured so as to be read by the reader 62 by way of radio wave or electromagnetic induction. A wireless IC tag 401 with electromagnetic induction is configured with a loop antenna and an IC chip having a control circuit, memory, a rectifying circuit, and a transmission/reception circuit, and information related to a number of dots on the dice 40 is stored in the memory.
At this time, if electric power is transferred to the three antennas 63a, 63b, and 63c simultaneously, these antennas may interfere with each other since the detection areas thereof are mutually superimposed. For this reason, based on the instruction signal from the controller 2, by transferring the electric power to each of the three antennas 63a, 63b, and 63c in a predetermined order, the antenna 63 that detects the wireless IC tag 401 is switched. More specifically, when the reader 62 receives an instruction signal for reading the wireless IC tag 401 from the controller 2, the reader 62 reads and executes a predetermined program stored in a storage unit (not shown) of the reader 62. This program determines the order of transferring the electric power to a plurality of the antennas 63, which detect the wireless tag 401, and switches the antenna 63 to which the electric power is transferred. This program includes transmitting a command that commands to transmit predetermined information to the wireless IC tag 401. By executing this program, the reader 62 turns on a plurality of the antennas 63 in a predetermined order and reads information of the wireless IC tag 401.
When the reader 62 receives information received from the antenna 63 and stored in the wireless IC tag 401, the reader 62 transmits the information thus received to the controller 2. At this time, in the wireless IC tag 401, information stored in the memory is encoded (source coding) and further encoded for complying with a transmission channel (transmission coding). Then, upon transmitting the information to the reader 62, the wireless IC tag 401 transmits by modulating into an analogue waveform. The reader 62 demodulates the data thus modulated and returns it to a digital waveform, and further decodes it to the original state and transmits information to the controller 2.
Die
A die 40 is described with reference to
A die 40 is composed of a core portion 402, an intermediate portion 403, and a covering portion 404, and the wireless IC tags 401 are disposed between the core portion 402 and the intermediate portion 403. These wireless IC tags 401 are disposed in each face of 6 faces of the die 40.
The core portion 402 is a substantially cubic member which is formed by cutting off corners of the cube. At the substantially central portions of each of the faces of the core portion 402, concave portions are formed in order to embed the wireless IC tags 401, and the wireless IC tags 401a, 401b, 401c, 401d, 401e, and 401f are disposed at each of the six concave portions.
The intermediate portion 403 is configured by combining a first intermediate portion 403a with a second intermediate portion 403b which are larger than the core portion 402 and are formed by dividing a substantially cubic body in half. The first intermediate portion 403a and the second intermediate portion 403b have concave portions formed on the insides thereof that each fit half of the core portion 402. Then, for example, by covering the core portion 402 on which the wireless IC tags 401 are embedded, by the first intermediate portion 403a from above and the second intermediate portion 403b from below, the core portion 402 is covered by the intermediate portion 403.
The covering portion 404 is configured by combining a first external portion 73a and a second external portion 73b which are slightly larger than the intermediate portion 72 and are formed by dividing a substantially cubic body in half. The first covering portion 404a and the second covering portion 404b have concave portions formed on the insides thereof that each fit half of the intermediate portion 403. For example, by covering the intermediate portion 403 by the first covering portion 404a from left and the second covering portion 404b from right, the intermediate portion 403 is covered by the covering portion 404.
It should be noted that it is possible to apply a film-type tag as the wireless IC tag. In this case, it is not necessary to form concave portions in the core portion 402, and it is possible to mount by attaching directly on the core portion 402. On the other hand, in order to reduce flexure of the wireless IC tag in the dice 40, it is particularly preferable that a hard plastic member such as ABS resin is applied to the covering portion 404.
The wireless IC tag 401 can appropriately employ an active tag which embeds a battery, a passive tag operated using electric power transferred from a reader/writer, and a semi-passive tag using electric power of a battery for a sensor operation. Furthermore, appropriate combinations for the wireless IC tag 401 as a reader can be employed. In the present embodiment, a passive tag is employed. In addition, reading the wireless IC tags may not only be done by the non-contact type, but also a contact type. In addition, the reader is not limited thereto, and anything that is appropriately designed with the object of being read may be employed.
Here, in the present embodiment, the number of dots of a face, opposing the face on which the wireless IC tag 401 is embedded, is determined as the number of dots of the dice 40.
More specifically, “one” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “six”. “Two” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “five”. “Six” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “one”. “Five” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “two”. “Three” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “four”. Finally, “four” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “three”.
Then, in a state in which the dice 40 are stopped, the reader 62 reads the wireless IC tag 401 on a face that is in contact with the playing board 41a (in other words, a face facing toward the lower side of the dice 40). Then, since data of a number of dots for a face opposite to the face is stored in the wireless IC tag 401 of the face thus read, the face facing the upper side when the dice 40 come to rest is recognized as a number of dots being appeared.
For example, in the dice 40, in a case in which a face that is in contact with the playing board 41a is a face of which number of dots is “six”, the reader 62 reads data of the IC tag 401 which is embedded in the face of “six”. Data of the number of dots stored in the wireless IC tag 401 of the face “six” is “one”, which is the number of dots on the face facing opposing the face of “six”, the number of dots on the dice 40 is recognized as “one”.
Furthermore, the memory of the wireless IC tag 401 includes information of a color in which the dice 40 is made. For example, in a case in which the die 40a is made to be red, the memory of the wireless IC tag 401 that is embedded in the red die 40a includes information indicating that the color is “red”.

Modified examples of the first embodiment are described with reference to
A first modified example is described with reference to
Four antennas 71 in the detection device 61 of the first modified example are provided. Each of these four antennas 71a, 71b, 71c, and 71d is formed in a shape enclosed by one arc, two lines indicating a radius passing through both ends of the one arc, and a line shorter than the one arc and concentric with the one arc. In addition, an angle of an inside corner, which is formed by an extended straight line indicating the radius, is no greater than 180 degrees. That is, each of the shapes of the four antennas 71a, 71b, 71c, and 71d is formed so that an angle thereof is smaller than that of a semicircle. In the present embodiment, each of the shapes is formed in a loop-shape of a substantial quarter circle. Then, a portion of the one antenna 71 is disposed so as to be superimposed with a portion of the other antenna 71.
In addition, each of the antennas 71a, 71b, 71c, and 71d are connected to the reader 62 by way of fixed lines.
It should be noted that, in the first modified example, although a portion of the detection area that forms each of the antennas 71a, 71b, 71c, and 71d is disposed so as to be mutually superimposed, in addition to this, a circular antenna may be disposed substantially at the center of the playing board 41a. In this case, it is preferable that the circular antenna is disposed so as to be superimposed with each of the portions of the antennas 71a, 71b, 71c, and 71d. This can prevent a situation in which the wireless IC tag 401 cannot read superimposed portions of antenna lines or the center area of the playing board 41a.
A second modified example is described with reference to
Regarding antennas in a detection device 61 of the second modified example, a transmission antenna 72 and reception antennas 73a, 73b, 73c, and 73d (hereinafter, a reception antenna 73 in a case of being referred collectively) are provided, respectively.
As shown in
Four reception antennas 73 are disposed so as to be mutually superimposed below the transmission antenna 72. These four antennas 73a, 73b, 73c, and 73d are composed of a plurality of lines disposed in parallel along a first direction and a plurality of lines disposed in parallel along a second direction and that perpendicularly intersects to the first direction. That is, the four antennas 73a, 73b, 73c, and 73d are formed in a grid pattern. Then, a circumference of the reception antenna 73 is formed to be circular so as to fit the shape of the playing board 41a.
As shown in
In addition, as shown in
Furthermore, as shown in
Thus, each of the reception antennas 73a, 73b, 73c, and 73d is disposed to be dislocated in a predetermined direction. Although it is shown in
A third modified example is described with reference to
Three antennas 74 in the detection device 61 of the third modified example are provided. Among these three antennas 74a, 74b, and 74c, the antenna 74a is disposed substantially at the center of the playing board 41a as a field on which the dice 40 roll, and is formed to be a loop-shape of substantial circular shape. In addition, the antennas 74b and 74c are formed in a shape enclosed by one arc, two lines respectively indicating a radius passing through both ends of the one arc, and a line shorter than the one arc and concentric with the one arc. In addition, an angle of an inside corner, which is formed by an extended straight line indicating the radius, is at least 180 degrees. That is, each of the shapes of the antennas 74b and 74c is formed so that an angle thereof is at least that of a semicircle. In the present embodiment, each of the shapes is formed in a loop-shape of a substantial semicircle. Each of the shapes is formed in a loop-shape which forms a shape in which two concentric semicircles are tied together by a straight line (a so-called semi-circular doughnut shape). Then, the antennas 74b and 74c are disposed so that bottom side portions of the semicircles thereof face each other and portions of the areas formed by being enclosed with the antenna 74b or 74c are mutually superimposed.
In addition, each of the antennas 74a, 74b, and 74c are connected to the reader 62 by way of fixed lines.
A second embodiment is described with reference to FIGS. 18 and 19. The second embodiment is different from the first embodiment in regard to a location where an antenna is disposed and a shape thereof. In the following, parts different from those of the first embodiment are mainly explained, and explanations of parts that are the same as in the first embodiment are omitted. It should be noted that the same numerals are used in a case in which parts thereof are the same as in the first embodiment.
In the second embodiment, only an antenna 75 of the reader 62 is disposed at a cover member 42 that covers an upper side of the playing board 41a. In addition, the antenna 75 is formed in a loop-shape so as to follow an inner side of the cover member 42 at a predetermined distance from an upper face of the playing board 41a. A predetermined distance from the upper face of the playing board 41a depends on the size of the dice 40. In the present embodiment, the antenna 75 reads data stored in the wireless IC tag 401 that is disposed on a face facing an upper side in a state in which the die 40 comes to rest. Thus, the antenna 75 is disposed at a location where it can read a face of the die 40 facing the upper side.
The playing board 41a includes a playing board main body 411 and a cushion member 412 that is disposed on the surface of the playing board main body 411, without an antenna base portion 413, as in the first embodiment.
According to the first embodiment, three antennas 63a, 63b, and 63c of the reader 62 are disposed in a loop-shape, respectively, in the playing board 41a as a field where the dice 40 having the wireless IC tags 401 on each face thereof roll. Since the portions of the areas formed by these three antennas 63a, 63b, and 63c are disposed so as to be mutually superimposed, the numbers of dots on the dice 40 can be detected regardless of position on the playing board 41a.
According to the first embodiment, the reader 62 that has received an instruction signal from the controller 2 supplies electric power to each of the three antennas 63a, 63b, and 63c in a predetermined order according to the instruction signal. Thus, the antenna 63 detects the dice 40 one by one in sequence. In this way, it is possible to prevent interference caused by simultaneous detection.
While an embodiment of the gaming machine according to the present invention has been described, it is to be understood that the above description is intended to be illustrative, and not restrictive, and any changes in design may be made to specific configurations such as various means. Moreover, it should be understood that the advantages described in association with the embodiments are merely a listing of most preferred advantages, and that the advantages of the present invention are by no means restricted to those described in connection with the embodiments.
According to the first embodiment, although the wireless IC tag 401 is a passive tag, the present invention is not limited thereto, and for example, an active tag may be employed. In addition, although electromagnetic induction is employed as a communication mode, the present invention is not limited thereto, and radio waves may be employed.
According to the first embodiment, although the antennas 63a, 63b, and 63c that transfer electric power are switched by executing a predetermined program by the reader 62, the present invention is not limited thereto. For example, it may be configured that the controller 2 transmits to the reader 62 a command for switching the antennas 63a, 63b, and 63c which are turned ON in a predetermined order and the reader 62 performs according to the command.
Embodiments of the present invention will be described below with reference to the accompanying drawings.
The detection device 61 is composed of a moving part and a detection device main body. The moving part has disposed therein at least a playing board 41a as a field on which the dice 40 roll and which supports a plurality of the dice 40a, 40b, and 40c (see
The reader 62 reads information stored in wireless IC tags 401a, 401b, 401c, 401d, 401e, and 401f (hereinafter, the wireless IC tag 401) that are embedded on each face of the dice 40, and decodes and transmits the information thus read to the controller 2. In the present embodiment, communication between the reader 62 and the wireless IC tag 401 is performed by way of electromagnetic induction. That is, the reader 62 flows current to the antenna 63 based on an instruction signal from the controller 2 and transmits a predetermined command to the wireless IC tag 401. Then, a magnetic field is altered within the area surrounded by the loop-shaped antenna 63 in which the current flew. Along with the alteration of magnetic flux in this magnetic field, electromotive force is generated within the loop antenna that is included in the wireless IC tag 401 which is disposed within the area. Herewith, electric power is transmitted to the wireless IC tag 401, whereby communication with the wireless IC tag 401 is performed.
In the present embodiment, three antennas 63 of the reader 62 are provided and disposed so that at least a portion of each of the detection areas thereof is mutually superimposed (see
Furthermore, the antennas 63b and 63c are formed so that four areas of substantially triangular shape depict a cross shape around an apex thereof, and bottom portions of substantially triangular shape are formed with a curve so as to follow the circumference of the playing board 41a. Thus, the antennas 63b and 63c are formed so that the width of the edges thereof is larger at the outer side than the center portion of the playing board 41a. Then, the antennas 63b and 63c are disposed so that the areas of substantially triangular shape thereof are disposed alternately and portions of the areas of substantially triangular shape are disposed to be mutually superimposed. More specifically, a lateral portion of the area of substantially triangular shape of an antenna is disposed so as to be superimposed with a portion of the area of substantially triangular shape of another antenna. Thus, the antennas 63b and 63c are loop antennas formed in a loop-shape so as to be the abovementioned shape.
In the present embodiment, each of the wireless IC tags 401 disposed on a plurality of the dice 40 is read by a single reader 62. Under the abovementioned RFID system, an anti-collision function can be employed which can read a plurality of wireless IC tags by a single reader. For the anti-collision function, there are FIFO (first in first out) type, multi-access type, and selective type, which communicate with a plurality of the wireless IC tags sequentially. FIFO type is a mode to communicate with a plurality of the wireless IC tags sequentially in the order in which each wireless IC tag enters an area in which an antenna can communicate therewith. Multi-access type is a mode that is able to communicate with all the wireless IC tags, even if there is a plurality of the wireless IC tags simultaneously in the area in which an antenna can communicate with the wireless IC tags. Selective type is a mode that is able to communicate with a specific wireless IC tag among a plurality of the wireless IC tags in the area in which an antenna can communicate therewith. By employing the abovementioned modes, it is possible to read a plurality of the wireless IC tags with a single reader.
The wireless IC tag 401 is configured so as to be read by the reader 62 by way of radio wave or electromagnetic induction. The wireless IC tag 401 is configured with a loop antenna and an IC chip having a control circuit, memory, a rectifying circuit, and a transmission/reception circuit, and information related to a number of dots on the dice 40 is stored in the memory. Details thereof are described later.
The first communication portion 65 and the second communication portion 66 can communicate with each other wirelessly. The first communication portion 65 and the second communication portion 66 are disposed between the antenna 63 and the reader 62. The first communication portion 65 is connected to the antenna 63, and the second communication portion 66 is connected to the reader 62. Thus, various commands that are transmitted from the reader 62 toward the wireless IC tag 401 and reply information that the antenna 63 has received from the wireless IC tag 401 are mutually transmitted and received between the first communication portion 65 and the second communication portion 66. The reply information from the wireless IC tag 401 is, for example, information related to a number of dots on dice or other information stored in the memory of the wireless IC tag 401.
The first communication portion 65 also includes a transmission circuit that transmits electric power to the antenna 63 and a loop antenna (not shown) that performs wireless communication with the second communication portion 66.
Furthermore, the switch portions 67a, 67b, and 67c (hereinafter, the switch portion 67 in a case of being referred to collectively) are respectively provided between the first communication portions 65a, 65b, and 65c and the antennas 63a, 63b, and 63c that are respectively connected thereto. This switch portion 67 switches whether electric current is supplied to the antenna 63. In a case in which the switch portion 67 enters the on state, electric power is sent to the antenna 63 from the transmission circuit of the first communication portion 65. In addition, in a case in which the switch portion 67 is in the off state, electric power that is sent from the transmission circuit of the first communication portion 65 is turned off.
In the present embodiment, the switch portion 67 is composed of photo MOSFET (Metal Oxide Semiconductor Field Effect Transistor). Regarding this photo MOSFET, by the light of the light emitting diode, a photovoltaic cell charges a gate capacitance of a FET and increases gate-to-source voltage. Then, the FET conducts and the switch portion 67 enters the on state.
When the light emitting diode (LED) is turned off, not only discharge of a photovoltaic cell stops, but also an internal discharge switch automatically works to discharge a gate charge forcibly, which reduces the gate-to-source voltage, and thus the switch portion 67 enters the off state.
At this time, if electric power is transferred to the three antennas 63a, 63b, and 63c simultaneously, these antennas may interfere with each other. For example, in a case of transmitting an instruction signal for supplying electric power to the antenna 63a from the controller 2 to the reader 62a, the antennas 63b and 63c enter the off state, and it is required for the loops which are formed by the antennas 63b and 63c, respectively, to be cut. This is because, by forming a loop, since the magnetic field is also maintained, radio wave interference may be generated by a relationship with the antenna 63a in the on state.
Therefore, the controller 2 transmits instruction signals to the readers 62a, 62b, and 62c that control the antennas 63a, 63b, and 63c, respectively. Then, in a case of turning on a single antenna among the three antennas 63a, 63b, and 63c, the switch portions 67 of the other two antennas are turned to the off state, and a loop of the antenna which does not turn to the off state is cut. In this way, the antenna 63 can be switched between on and off states.
The controller 2 controls the entire gaming machine 1. Furthermore, in the present embodiment, the controller 2 includes a dealer used display 210 that is used by a dealer 5 who advances a game and a touch panel 211 provided at the dealer used display 210, and executes a control for the overall gaming machine 1 according to an operation of the dealer 5.
The stations 3 are terminals that players operate. The stations 3 accept bet operations by players sitting on chairs (not shown) provided in front of the stations 3 and pay out awards of games.
The station 3 includes an image display device 31, a game media acceptance device that accepts game media such as medals inserted to an insertion opening 321 and used for a game, an operation unit 33 composed of a shake button 331 to which a predetermined instruction is inputted by a player, a game information display unit 34 for displaying information related to a game, and the like. The player may participate in a game by operating the operation unit 33 or the like while viewing the image displayed on the image display device 31.
In the present embodiment, a shake button 331 and a select button 332 are provided at the operation unit 33. The shake button 331 is a button for performing an instruction that allows a player to start rolling dice at a predetermined timing. Furthermore, in a case other than the bet operation, the select button 332 is pushed for confirming the input that a player performed.
In addition, a speaker 35, which can output sound, is disposed on the upper right of the image display device 31 on each of the stations 3.
A plurality of buttons is provided on the side part of the image display device 31 on each of the stations 3. More specifically, a payout button 36 and a help button 37 are disposed thereat.
The payout button 36 is a button which is usually pressed at the end of a game, and when the payout button 36 is pressed, game media corresponding to credits that the player has acquired is paid out from the payout opening 322.
The help button 37 is a button that is pressed in a case where a method of operating the game is unclear, and upon the help button 37 being pressed, a help screen showing various kinds of operation information is displayed immediately thereafter on the image display device 31.
Another operation is performed by the player touching a display screen displayed on the image display device 31. Since a touch-sensitive sensor is installed on the surface of the image display device 31, various operations are recognized by the player touching through a so-called touch panel system.
The dice movable unit 4 rolls a plurality of the dice 40 used in a Sic Bo game. An award is determined based on a combination of numbers being appeared on an upper face (hereinafter, a number of dots on dice) when a plurality of the dice 40 is caused to roll and stop. In other words, a random number can be obtained by rolling a plurality of the dice 40.
The history display unit 91 displays history of a game such as including a number of dots on the dice. Details thereof are described later.
The external large-size monitor 500 is a display device that displays live images such as for advancement of a game, a demonstration screen, and the like.
Dice Movable Unit
A dice movable unit 4 is described with reference to
The dice movable unit 4 is configured so as to allow a plurality of the dice 40 to roll and stop. This dice movable unit 4 includes a shaking device 41 that is configured so as to allow the dice 40 to roll, a cover member 42 that covers an upper side of the shaking device 41 and is formed in a dome shape, and a unit main body 43 that houses the shaking device 41. In the present embodiment, the shaking device 41 rolls the three dice 40 (the die 40a, the die 40b, and the die 40c).
The cover member 42 is disposed so as to cover the overall top face of the playing board 41a. Furthermore, the cover member 42 is made of a transparent member in a substantially hemispherical shape and limits an area in which the dice 40 roll.
A plurality of the dice 40 is disposed at a space formed by the playing board 41a and the cover member 42. In the present embodiment, the dice 40 are substantially hexahedral and the IC tags are embedded in each face thereof. It should be noted that this wireless IC tag 401 is embedded in the surface of the dice 40 so as not to be visually recognized from the outside of the dice 40. For example, the dice 40 can be formed by disposing the wireless IC tag 401 at the surface of a member as a base of the dice 40 and then placing a member as a cover thereover.
The dice movable unit 4 includes lamps 44. The lamps 44 perform various rendered effects by emitting lights while the dice 40 are being rolled.
The shaking device 41 is formed in a substantially circular shape as viewed in a plane, supports a plurality of the dice 40, and includes the playing board 41a as a field in which a plurality of the dice 40 are rolled and a cylinder portion 45 that oscillates the playing board 41a vertically.
Since the playing board 41a is formed to be substantially planar, as shown in
Furthermore, the playing board 41a includes a playing board main body 411, a cushion member 412 that is disposed on the upper surface of the playing board main body 411, and an antenna base portion 413 that is disposed between the playing board main body 411 and the cushion member 412 and in which the antennas 63a, 63b, and 63c are disposed. It is preferable that members forming these are made of a non-metallic member. Since radio waves are susceptible to the interference of metal, if metal exists near the wireless IC tag 401, the communication range between the reader 62 and the wireless IC tag 401 is reduced, and thus it may prevent the wireless IC tag 401 from being read by the reader 62.
Then, the antennas 63a, 63b, and 63c, which are disposed at the antenna base portion 413, are connected to the first communication portion 65a, 65b, and 65c via a wire, respectively. The first communication portions 65a, 65b, and 65c are disposed respectively at the bottom face side of the playing board main body 411. Furthermore, the second communication portion 66 is disposed so as to face the first communication portions 65a, 65b, and 65c. The second communication portions 66a, 66b, and 66c are disposed on a side of the unit main body 43 of the dice movable unit 4. That is, the first communication portion 65 and the second communication portion 66 are disposed respectively at a side of the bottom face side of the playing board 41a so as to face each other. Thus, even in a case in which the playing board 41a moves along with the vertical movement of the cylinder portion 45, the positions of the first communication portion 65 and the second communication portion 66 are not dislocated, which can maintain a stable communication status. In a case in which the first communication portion 65 and the second communication portion 66 are disposed on a side face of the playing board 41a, it may cause a case in which the first communication portion 65 and the second communication portion 66 are not located so as to face each other after the movement of the playing board 41a, which may interrupt the communication therebetween. By disposing the first communication portion 65 and the second communication portion 66 so as to face each other at a side of the bottom face of the playing board 41a, it is possible to prevent such a situation.
Then, the reader 62 transmits the information received from the antenna 63 and stored in the wireless IC tag 401 to the controller 2. At this time, in the wireless IC tag 401, information stored in the memory is encoded (source coding) and further encoded for complying with a transmission channel (transmission coding). Then, upon transmitting the information to the reader 62, the wireless IC tag 401 transmits by modulating into an analogue waveform. The reader 62 demodulates the data thus modulated and returns it to a digital waveform, and further decodes it to the original state and transmits information to the controller 2.
Die
A die 40 is described with reference to
A die 40 is composed of a core portion 402, an intermediate portion 403, and a covering portion 404, and the wireless IC tag 401 is disposed between the core portion 402 and the intermediate portion 403. This wireless IC tag 401 is disposed in each face of 6 faces of the die 40.
The core portion 402 is a substantially cubic member which is formed by cutting off corners of the cube. At the substantially central portions of each of the faces of the core portion 402, concave portions are formed in order to embed the wireless IC tags 401, and the wireless IC tags 401a, 401b, 401c, 401d, 401e, and 401f are disposed at each of the six concave portions.
The intermediate portion 403 is configured by combining a first intermediate portion 403a with a second intermediate portion 403b which are larger than the core portion 402 and are formed by dividing a substantially cubic body in half. The first intermediate portion 403a and the second intermediate portion 403b have concave portions formed on the insides thereof that each fit half of the core portion 402. Then, for example, by covering the core portion 402 on which the wireless IC tags 401 are embedded, by the first intermediate portion 403a from above and the second intermediate portion 403b from below, the core portion 402 is covered by the intermediate portion 403.
The covering portion 404 is configured by combining a first external portion 404a and a second external portion 404b which are slightly larger than the intermediate portion 402 and are formed by dividing a substantially cubic body in half. The first covering portion 404a and the second covering portion 404b have concave portions formed on the insides thereof that each fit half of the intermediate portion 403. For example, by covering the intermediate portion 403 by the first covering portion 404a from left and the second covering portion 404b from right, the intermediate portion 403 is covered by the covering portion 404.
It should be noted that it is possible to apply a film-type tag as the wireless IC tag. In this case, it is not necessary to form concave portions in the core portion 402, and it is possible to mount by attaching directly on the core portion 402. On the other hand, in order to reduce flexure of the wireless IC tag in the dice 40, it is particularly preferable that a hard plastic member such as ABS resin is applied to the covering portion 404.
The wireless IC tag 401 can appropriately employ an active tag which embeds a battery, a passive tag operated using electric power transferred from a reader/writer, and a semi-passive tag using electric power of a battery for a sensor operation. Furthermore, appropriate combinations for the wireless IC tag 401 as a reader can be employed. In the present embodiment, a passive tag is employed. In addition, reading the wireless IC tags may not only be done by the non-contact type, but also a contact type.
In addition, the reader is not limited thereto, and anything that is appropriately designed with the object of being read may be employed.
Here, in the present embodiment, the number of dots of a face, opposing the face on which the wireless IC tag 401 is embedded, is determined as the number of dots of the dice 40.
More specifically, “one” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “six”. “Two” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “five”. “Six” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “one”. “Five” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “two”. “Three” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “four”. Finally, “four” is stored as data of the number of dots in the wireless IC tag 401 on the face of which the number of dots is “three”.
Then, in a state in which the dice 40 are stopped, the reader 62 reads the wireless IC tag 401 on a face that is in contact with the playing board 41a (in other words, a face facing toward the lower side of the dice 40). Then, since data of a number of dots for a face opposite to the face is stored in the wireless IC tag 401 of the face thus read, the face facing the upper side when the dice 40 come to rest is recognized as a number of dots being appeared.
For example, in the dice 40, in a case in which a face that is in contact with the playing board 41a is a face of which number of dots is “six”, the reader 62 reads data of the IC tag 401 which is embedded in the face of “six”. Data of the number of dots stored in the wireless IC tag 401 of the face “six” is “one”, which is the number of dots on the face facing opposing the face of “six”, the number of dots on the dice 40 is recognized as “one”.
Furthermore, the memory of the wireless IC tag 401 includes information of a color in which the dice 40 is made. For example, in a case in which the die 40a is made to be red, the memory of the wireless IC tag 401 that is embedded in the red die 40a includes information indicating that the color is “red”.
Controller
The controller 2 perform control of the entire game and transmits to the reader 62 of the dice movable unit 4 an instruction signal for supplying electric power to the antennas 63a, 63b, and 63c.

More specifically, the CPU 81 accepts bet information transmitted from each station 3. Furthermore, the CPU 81 performs win determination processing based on the number of dots on the dice 40 and the bet information transmitted from each station 3, and calculates the amount of an award paid out in each station 3 with reference to the payout table stored in the ROM 82.
Modified examples of the third embodiment are described with reference to
A first modified example is described with reference to
Four antennas 71 in the detection device 61 of the first modified example are provided. These four antennas 71a, 71b, 71c, and 71d are each formed in a loop-shape of a substantial quarter circle, and a portion of the one antenna 71 is disposed so as to be superimposed with a portion of the other antenna 71.
In addition, four first communication portions 65, four second communication portions 66, and four readers are respectively provided to correspond to the number of the antennas 71. Then, the four readers 62a, 62b, 62c, and 62d are connected with the controller 2, respectively.
The second modified example is described with reference to
Three antennas 74 in the detection device 61 of the third modified example are provided. Among these three antennas 74a, 74b, and 74c, the antenna 74a is disposed substantially at the center of the playing board 41a as a field on which the dice 40 roll, and is formed to be a loop-shape of substantial circular shape. Regarding the antennas 74b and 74c, each of the shapes is formed in a loop-shape which forms a shape in which two concentric semicircles are tied together by a straight line (a so-called semi-circular doughnut shape). Then, the antennas 74b and 74c are disposed so that bottom side portions of the semicircles thereof face each other and portions of the areas formed by being enclosed with the antenna 74b or 74c are mutually superimposed.
A Fourth embodiment is described with reference to
In the fourth embodiment, only an antenna 75 of the reader 62 is disposed at a cover member 42 that covers an upper side of the playing board 41a. In addition, the antenna 75 is formed in a loop-shape so as to follow an inner side of the cover member 42 at a predetermined distance from an upper face of the playing board 41a. A predetermined distance from the upper face of the playing board 41a depends on the size of the dice 40. In the present embodiment, the antenna 75 reads data stored in the wireless IC tag 401 that is disposed on a face facing an upper side in a state in which the die 40 comes to rest. Thus, the antenna 75 is disposed at a location where it can read a face of the die 40 facing the upper side.
The playing board 41a includes a playing board main body 411 and a cushion member 412 that is disposed on the surface of the playing board main body 411, without an antenna base portion 413, as in the third embodiment. Then, the first communication portion 65 is disposed at the bottom face side of the playing board main body 411.
According to the third embodiment, three antennas 63a, 63b, and 63c of the reader 62 are disposed in a loop-shape, respectively, in the playing board 41a as a field where the dice 40 having the wireless IC tags 401 on each face thereof roll. Since the portions of the areas formed by these three antennas 63a, 63b, and 63c are disposed so as to be mutually superimposed, the numbers of dots on the dice 40 can be detected regardless of position on the playing board 41a.
According to the third embodiment, the reader 62 that has received an instruction signal from the controller 2 supplies electric power to each of the three antennas 63a, 63b, and 63c in a predetermined order according to the instruction signal. Thus, the antenna 63 detects the dice 40 one by one in sequence. In this way, it is possible to prevent interference caused by simultaneous detection.
According to the abovementioned embodiment, the first communication portion 65 and the second communication portion 66 are provided that perform wireless communication between the reader 62 and the antenna 63. Thus, since it is possible to omit a member such as a wire that moves along with the movement of the moving part such as the playing board 41a and the cylinder portion 45, it is possible to prevent deterioration of a member due to the movement of the moving part. In addition, by preventing deterioration, it is possible to reduce the frequency of maintenance and increase operation availability.
While an embodiment of the gaming machine according to the present invention has been described, it is to be understood that the above description is intended to be illustrative, and not restrictive, and any changes in design may be made to specific configurations such as various means. Moreover, it should be understood that the advantages described in association with the embodiments are merely a listing of most preferred advantages, and that the advantages of the present invention are by no means restricted to those described in connection with the embodiments.
According to the third embodiment, although the wireless IC tag 401 is a passive tag, the present invention is not limited thereto, and for example, an active tag may be employed. In addition, although electromagnetic induction is employed as a communication mode, the present invention is not limited thereto, and radio waves may be employed.
