Description

The present invention relates to a roulette device that stores a ball in a ball storage unit corresponding to a mark arranged on a roulette wheel , and discharges air compressed by a compressor from the ball storage unit and the bank passage, and the depth of the ball storage unit. It is related with the roulette device which made it easy to confirm the position of the ball in the roulette wheel and improved the playability by making the depth less than the diameter of the ball with respect to the inclined surface formed between the bank passage.

A so-called medal game using a medal as a game medium such as a roulette game machine is a game that can be started by a player purchasing or borrowing a plurality of medals with a medal lending machine and inserting the medals into the gaming machine. Yes, if the player wins the game, a predetermined number of medals are paid out. Therefore, a player who has obtained a large number of medals can continue to enjoy the game without purchasing or borrowing new medals.
Here, particularly in the roulette game machine, when the player selects a mark (number) arranged on the roulette board, the roulette board rotates and the thrown ball rolls in the roulette board. When the rotation of the roulette wheel is weakened and the ball is received and held in any groove in the roulette wheel, the mark (number) selected by the player coincides with the mark (number) containing the ball (winning) ) Is determined. Here, when it is determined that the same mark (number) is received (held) in the groove, the medal is paid back to the player at a predetermined magnification.
Conventionally, in the roulette game machine, a ball collecting mechanism for collecting the ball used in the previous game once from the roulette board is provided in order to fire again onto the roulette board. For example, as shown in Japanese Patent Application Laid-Open No. 8-229191, a ball passage hole is formed in each ball receiving portion of the rotating side wheel, and a flange for closing the ball passage hole is formed in the stationary side wheel, and a part of the flange is formed. Form in the notch. Then, an opening / closing plate that opens and closes the notch when the solenoid is driven is provided at the notch, and when the ball is collected, the notch is opened, so that a mechanism for lifting the rotation-side wheel is not provided, and the ball is removed from the wheel. A roulette game machine in which the bucket is made small and the bucket can be miniaturized is described.
JP-A-8-229191 (pages 3 to 5, FIGS. 4 to 6)

However, in the roulette game machine described in Patent Document 1 described above, a complicated mechanism for temporarily storing the ball collected from the roulette board below the roulette board and re-launching it on the roulette board is necessary. .
In addition, each ball storage unit requires a movable part such as a shutter for opening and closing the ball passage hole, which increases the cost and is likely to cause the game to stop due to a malfunction of the movable part. Was complicated.

In addition, since it is necessary to form a ball passage hole in each ball accommodating portion, the ball accommodating portion needs to have a certain depth or more, and a part of the ball accommodated in the ball accommodating portion is buried from the roulette wheel. It was. On the other hand, the roulette wheel needs to be formed with a launch opening for launching the collected balls onto the roulette wheel. Therefore, the roulette wheel has to be higher than a predetermined height. Specific examples will be described below with reference to FIGS. 30 and 31. FIG.
30 and 31 are schematic views showing a roulette device used in a conventional roulette game machine. As shown in FIG. 30, the conventional roulette device 100 is provided with a plurality of ball storage portions 102 formed in the circumferential direction of the roulette wheel 101. Further, the ball storage portion 102 is formed with a ball passage hole 104 for temporarily collecting the ball 103 stored in the ball storage portion 102 after the game is finished. A ball collection unit 105 for temporarily accommodating the ball 103 that has passed through the hole 104 is attached. On the other hand, a ball launch port 107 is formed in the bank passage 106 in which the ball 103 draws a circular motion. Then, the ball 103 collected through the ball passage hole 104 is once accommodated in the ball collection unit 105 and conveyed to a ball launcher (not shown). Thereafter, the ball 103 launched from the ball launcher is fired into the roulette wheel 101 from the ball launch port 107 and rolls on the roulette wheel 101.
Here, since it is necessary for the ball storage portion 102 to form a ball passage hole 104 for conveying the ball 103 to the outside, the height h1 of the ball storage portion 102 needs to be set higher than the diameter of the ball 103. . Furthermore, since it is necessary to form the ball outlet 107 in the bank passage 106, the height h2 of the roulette wheel 101 needs to be increased to a predetermined value (for example, 143 mm) or more.
Therefore, as shown in FIG. 31, a player 109 playing a game on the game device 108 having the roulette device 100 at the height H1 can check the ball 103 no matter which ball storage portion 102 is stored. The viewing angle α becomes narrower. Accordingly, the height of the viewpoint of the player 109 who performs the game needs to be H2 or more. Specifically, when H1 = about 900 mm and α = 50 degrees are set, H2 = about 1400 mm, and the general player 109 checks the ball 103 in the roulette wheel 101 unless he stands. I couldn't do it. In addition, in particular, the player 109 with a low viewpoint has to move not only to stand but also to move the standing position. This makes it difficult for the player to check the ball and lowers the game playability.

  As shown in FIG. 2, the roulette device 2 includes a roulette wheel 12 having a rolling area where the ball 11 rolls during the game, a support base 13 for supporting the roulette wheel 12 inside the roulette game machine 1, Compressor 14 that takes in air and compresses it to a predetermined pressure, Air tubes 15 and 16 that send air compressed by compressor 14, and the air that flows through air tubes 15 and 16 provided at the midpoints of air tubes 15 and 16, respectively. This is basically composed of a first on-off valve 17 and a second on-off valve 18 for adjusting the pressure.

The roulette wheel 12 is basically composed of a frame body 21 fixed to the support base 13 and a rotating disk 22 housed and supported rotatably inside the frame body 21. A large number (38 in the first embodiment) of concave ball storage portions 23 are formed on the upper surface of the rotating disk 22 in the circumferential direction. The ball storage portion 23 is partitioned by a substantially triangular partition wall 23A (see FIG. 5), and the upper surface of the rotating disk 22 in the outward direction of each ball storage portion 23 corresponds to each ball storage portion 23. A number display plate 24 on which numbers “0”, “00”, “1” to “36” as graphic characters are displayed is formed. The rotating disk 22 is driven by a drive motor (not shown) provided inside the roulette device 2 immediately after the ball 11 starts rolling until a predetermined time elapses after the ball 11 is stored in the ball storage unit 23. The frame body 21 is rotated in a predetermined direction (for example, clockwise direction) at a predetermined speed (for example, 2π [rad / s] to 0.2π [rad / s]).
Further, when installed in the roulette game machine 1, the entire upper portion of the roulette wheel 12 is covered with a hemispherical transparent acrylic cover member 25 (see FIG. 1). Thereby, it is possible to hold the ball 11 rolling on the roulette wheel 12 so as not to jump out of the roulette wheel 12 during the game. In addition, foreign matters and the like are prevented from entering the roulette wheel 12 so that illegal acts and the like are not performed.

  Here, the rolling region where the ball 11 actually rolls in the roulette wheel 12 includes a first inclined surface 28 </ b> A formed on the outer peripheral side of the frame body 21 and a second inclined surface formed on the inner peripheral side of the rotating disk 22. It consists of one inclined surface 28 having a predetermined angle (15 degrees in the first embodiment) formed by the inclined surface 28B. The inclined surface 28 is inclined upward from the center direction of the roulette wheel 12 to the outer peripheral direction, and a ball storage portion 23 and a bank passage 29 described later are continuously formed through the inclined surface 28.

  A bank passage 29 is provided around the outer peripheral edge of the frame body 21. The bank passage 29 is a passage that guides the ball 11 against the centrifugal force of the ball 11 that rolls on the roulette wheel 12 and rolls the ball 11 in a circular orbit. The bank passage 29 is formed endlessly with respect to the roulette wheel 12 by a guide wall 30 erected in the vertical direction, and further, a wall portion is continuous with the bank passage 29 at the upper end corresponding to the outer peripheral portion thereof. 31 is formed. The wall portion 31 is a member that urges the ball 11 that rotates on the bank passage 29 inward so as not to jump out of the roulette wheel 12.

Then, the ball 11 applied with acceleration force by air discharged from the first discharge port 35 and the second discharge port 36 which will be described later gradually increases in speed and rotates along the bank passage 29. On the other hand, when the discharge of air from the second discharge port 36 is stopped, the rotation speed of the ball 11 decreases and the centrifugal force is lost, the ball 11 rolls down the inclined surface 28 and moves toward the inside of the roulette wheel 12 to rotate. To 22.
Then, the ball 11 rolling on the rotating disk 22 passes on the number display plate 24 of the rotating rotating disk 22 and is stored in one of the ball storage sections 23, and corresponds to the ball storage section 23 in which the balls 11 are stored. The number written on the number display board 24 to be used is the winning number.

  Further, a part of the partition wall 23A that forms the ball housing portion 23 is cut out, and a transmission type optical sensor including a light projector 32 and a light receiver 33 is provided (see FIG. 5). The infrared rays emitted from the light projector 32 of one partition wall 23A forming the ball storage portion 23 reach the light receiver 33 of the other partition wall 23A, but when the ball 11 enters the ball storage portion 23, light is emitted. The presence of the ball 11 can be detected by being blocked. Therefore, when the ball 11 enters a certain ball storage portion 23, the presence of the ball 11 is detected by an optical sensor composed of a projector 32 and a light receiver 33, and transmitted to a main control CPU 80 (see FIG. 9) described later. Based on the result, the main control CPU 80 determines the winning number.

On the other hand, the depth L1 of the ball housing portion 23 with respect to the inclined surface 28 is formed to be shallower than the diameter D of the ball 11. FIG. 7 is a schematic view showing a ball storage unit according to the first embodiment.
As described above, the ball storage portion 23 is a space for storing a total of 38 balls 11 partitioned in the circumferential direction by the partition wall 23A. Since the depth L1 of the ball storage portion 23 is configured to be shallower than the diameter D of the ball 11, when the ball 11 is stored in the ball storage portion 23 as shown in FIG. There is no possibility that the ball 11 is buried in the unit 23, and the player can easily confirm the position of the ball 11 stored in the ball storage unit 23 during the game. Therefore, gameability is improved.

In addition, as described above, in the roulette device 2 according to the first embodiment, the compressed air is discharged to the ball 11 so that the ball 11 is repeatedly rolled without being collected from the roulette wheel 12. Therefore, a complicated mechanism such as a movable part or a launching device for collecting the ball 11 is not required. Further, the depth L1 of the ball housing portion 23 can be made shallower than the diameter D of the ball 11 (see FIG. 7). As a result, as shown in FIG. 5, the height h3 of the roulette wheel 12 can be lowered. Therefore, the viewing angle β of the roulette device 2 for confirming the ball 11 can be widened, the player can easily confirm the ball, and the game performance is improved.
Furthermore, since the ball storage portion 23 and the bank passage 29 are continuously formed by a single inclined surface 28 rising from the ball storage portion 23 to the bank passage 29 at a predetermined inclination angle, It becomes easy to confirm the ball 11 stored in the portion 23.

  Next, the first discharge port 35 and the second discharge port 36 provided in the roulette wheel 12 will be described with reference to FIGS. Here, when transferring the ball 11 on the roulette wheel 12, the roulette device 2 according to the first embodiment uses the compressed air pressure as the power source. Specifically, ambient air is taken in and compressed to a predetermined pressure (for example, 1 Mpa) by a compressor 14 (see FIG. 2) provided below the roulette device 2, and the compressed air is passed through the air tubes 15 and 16.

  As shown in FIG. 5, the first discharge port 35 is formed on an inner wall 37 that forms the ball storage portion 23 together with the partition wall 23 </ b> A corresponding to each ball storage portion 23. In the first embodiment, 38 ball storage portions 23 corresponding to the numbers “0”, “00”, “1” to “36” are formed, and therefore the first discharge ports 35 are provided at 38 locations. Is formed. The first discharge port 35 is formed in the circumferential direction from the center of the roulette wheel 12, and the air discharged from the first discharge port 35 is a bank passage provided at the outer peripheral edge of the roulette wheel 12. 29 is emitted.

  On the other hand, an annular launching air pipe 38 is installed on the back side surface of the inner wall 37 where the first discharge port 35 is formed. The launching air pipe 38 is connected to the air tube 15, and the first discharge ports 35 are formed at a total of 38 locations on the outer periphery thereof. Therefore, the air transported from the air tube 15 once flows into the launching air pipe 38 and then is discharged all at once from the first discharge ports 35 provided at the 38 locations to the ball storage portion 23. The balls 11 stored in any of the ball storage portions 23 start rolling in the direction of the bank passage 29 against the inclination of the inclined surface 28 by the air pressure of the discharged air.

  Moreover, the 2nd discharge port 36 is formed in the guide wall 30 which comprises the bank channel | path 29 as shown in FIG. 6 with the predetermined space | interval (45 degree space | interval in 1st Embodiment). The second discharge ports 36 are formed in the circumferential direction of the bank passage 29, that is, in the tangential direction of the roulette wheel 12. The air discharged from the second discharge ports 36 is the bank of the roulette wheel 12. A layer of air flowing in a clockwise direction along the passage 29 is created (see FIG. 16).

On the other hand, an annular rotating air pipe 39 is installed on the back side surface of the guide wall 30 in which the second discharge port 36 is formed. The rotation air pipe 39 is connected to the air tube 16, and the air conveyed from the air tube 16 flows into the rotation air pipe 39 and is discharged from the second discharge ports 36 provided at eight locations all at once. . Thereby, the ball 11 that has rolled to the bank passage 29 based on the air discharged from the first discharge port 35 starts rolling in the clockwise direction by the layer of air that flows annularly along the bank passage 29. To do.
Further, when the discharge of air from the second discharge port 36 is stopped, the air layer formed along the bank passage 29 disappears, and the rotation speed of the ball 11 gradually decreases and the centrifugal force is lost. Then, it rolls down along the inclination of the inclined surface 28, goes to the inside of the roulette wheel 12, and reaches the rotating disk 22 that rotates. Then, it is stored in one of the ball storage portions 23 formed on the rotating disk 22. Thereby, the winning number is determined by the roulette device 2, and the roulette game machine 1 pays out medals based on the determined number and the bet information bet by the player and ends the game.
Further, when air is subsequently discharged from the first discharge port 35, the ball 11 stored in the ball storage unit 23 starts rolling again, and the next game can be continuously performed.

As described above, without recovering the ball 11 from the roulette wheel 12, a force is applied to the ball 11 by the air pressure discharged from the first discharge port 35 and the second discharge port 36, and the ball 11 is moved to the ball storage unit 23. Storage can be performed repeatedly. Therefore, maintenance work is facilitated and the cost of the apparatus can be reduced without requiring a complicated mechanism such as a movable part for collecting the ball 11 or a launching device.
The details of the rolling mechanism of the ball 11 by the first discharge port 35 and the second discharge port 36 will be described later.

  On the other hand, the image display device 7 is a so-called touch panel type liquid crystal display with a touch panel 48 attached to the front surface, and can be selected by pressing an icon displayed on the liquid crystal screen with a finger or the like. FIG. 8 is a diagram showing an example of a display screen displayed on the image display device during the game.

  As shown in FIG. 8, a BET screen 51 having a table-type betting board 50 is displayed on the image display device 7 during the game of the roulette game machine 1. Then, the player can bet chips by using the credits on hand by operating the BET screen 51.

  Hereinafter, the BET screen 51 will be described with reference to FIG. On the table-type betting board 50 displayed on the BET screen 51, the same numbers “0”, “00”, “1” to “36” displayed on the number display plate 24 are displayed in a grid pattern. Has been. In addition, “odd number”, “even number”, “color type of number display board (red or black)”, “certain number range (for example,“ 1 ”to“ 12 ”, etc.)” are designated. Similarly, special BET areas for betting chips are also arranged in a grid pattern.

  A result history display section 55, a unit BET button 56, a refund result display section 57, and a credit amount display section 58 are displayed below the table-type betting board 50 in order from the left side of the screen.

  The result history display unit 55 displays the game up to the previous time (here, in one game, the player bets in each satellite 4, the ball 11 falls into the ball storage unit 23, and credits are paid out based on the winning number. The result of the winning number is displayed on the list. At that time, when one game is over, a new winning number is added and displayed from the top, and it is possible to check the history of the winning numbers of up to 16 games.

The unit BET button 56 is a button for betting on a BET area designated by the player (on the grid of numbers and marks or on the line forming the grid). There are four types of unit BET buttons: a 1BET button 56A, a 5BET button 56B, a 10BET button 56C, and a 100BET button 56D.
The player first designates a BET area with a cursor 60 (to be described later) by directly pressing the screen with a finger or the like in the BET area to bet. In this state, when the 1BET button 56A is pressed, the player bets one chip at a time (every time the 1BET button 56A is pressed with a finger or the like, “1” → “2” → “3” →. Bet on (Increase). On the other hand, when the 10BET button 56C is pressed, bets are placed in units of 10 chips (the number of bets increases in the order of “10” → “20” → “30” →... Each time the 10BET button 56C is pressed with a finger or the like). It is possible. The operation of the 5BET button 56B and the 100BET button 56D is the same. Therefore, even when a large amount of chips are bet, the operation can be simplified.

  Further, the refund result display section 57 displays the number of bets on the player's chips in the previous game and the number of credits for the refund. Here, the number obtained by subtracting the number of bets from the number of payout credits is the number of credits newly acquired by the player in the previous game.

  Further, the credit amount display section 58 displays the number of credits owned by the current player. The number of credits decreases according to the number of bets (one credit per chip) when a chip is betted. In addition, when the bet number is won and credits are refunded, the number of credits corresponding to the number of refunds increases. If the number of credits owned by the player becomes 0, the game is over.

  A BET timer graph 59 is provided at the top of the table-type betting board 50. The BET timer graph 59 is a graph that displays the remaining time that the player can bet, and the red graph gradually extends to the right from the beginning of the game. And when it extends to the rightmost side, the betable time in the current game ends. Further, when the player's betting period ends in each satellite 4, that is, when the BET timer graph 59 reaches the rightmost side, air is discharged from the first discharge port 35 and stored in the ball storage unit 23. The rolling of the ball 11 is started.

On the table-type betting board 50, a cursor 60 indicating the BET area currently selected by the player is displayed, and a chip mark 61 indicating the number of chips bet and the BET area up to the present time is displayed. The number displayed on the chip mark 61 indicates the number of chips bet. For example, as shown in FIG. 8, a “7” chip mark 61 placed on a “18” cell indicates that seven chips are bet on the number “18”. A method of betting on only one number in this way is a betting method called “straight up”.
Also, the chip mark 61 of “1” placed at the intersection of the squares “5”, “6”, “8”, “9” has numbers “5”, “6”, “8”, “9” ”Indicates that one chip is betted covering the four numbers. A method of betting by covering four numbers in this way is a betting method called “corner betting”.

  Other betting methods include a “split bet” in which two numbers are covered on a line between two numbers, and three at the end of a horizontal row of numbers (a vertical row in FIG. 8). A “street bet” that covers and bets numbers (eg, “13”, “14”, “15”), “0”, “00” on the line between numbers “00” and “3”, “Five bet” to bet covering five numbers “1”, “2”, “3”, six between the numbers in two horizontal rows of numbers (vertical two rows in FIG. 3) Covering numbers (eg, “13”, “14”, “15”, “16”, “17”, “18”) and betting “line bet”, “2to1” above the grid Cover 12 numbers with “Column Bet”, “1st12”, “2nd12”, “ To bet covers 12 numbers each in the mass superior written and rd12 "there is a" Dozen bet ". Furthermore, using the six squares provided at the bottom of the table-type betting board 50, the color of the number display board ("red" or "black"), the odd number even number, and the number is 18 or less or 19 or more There is a method of betting by covering 18 numbers.

When a player places a bet on the BET screen 51 configured as described above, first, a BET area (a number or mark cell or a line forming a cell) where a bet is placed is displayed on the screen. Specify and press directly with your finger. As a result, the cursor 60 moves to the designated BET area.
Thereafter, by depressing each unit button (1BET button 56A, 5BET button 56B, 10BET button 56C, 100BET button 56D) of the unit BET button 56, medals corresponding to the number of units are bet on the designated BET area. For example, if the 10BET button 56C is pressed four times, the 5BET button 56B is pressed once, and the 1BET button 56A is pressed three times, a total of 48 medals can be bet.

Next, the structure which concerns on the control system of the roulette game machine 1 which concerns on 1st Embodiment is demonstrated based on FIG. FIG. 9 is a block diagram schematically showing a control system of the roulette game machine.
As shown in FIG. 9, the roulette game machine 1 includes a main control unit 83 including a CPU 80 for main control, a ROM 81, and a RAM 82, a roulette device 2 connected to the main control unit 83, and ten satellites 4 (see FIG. 9). 1), and a first on-off valve 17 and a second on-off valve 18. The satellite 4 control system will be described in detail later.

  The main control CPU 80 performs various processes based on the input signals supplied from the satellites 4 and the data and programs stored in the ROM 81 and the RAM 82, and sends command signals to the satellites 4 based on the results. Is transmitted to control each satellite 4 to advance the game. Further, the projector 32 and the light receiver 33 (see FIG. 5) provided in the roulette device 2 are controlled to determine the winning number of the ball storage unit 23 where the ball 11 has dropped. Based on the winning number obtained and the bet information transmitted from each satellite 4, the winning determination of the betted chip is performed, and the number of credits to be paid out in each satellite 4 is calculated.

  The ROM 81 is constituted by, for example, a semiconductor memory, and controls a program for realizing basic functions of the roulette game machine 1, each device in the roulette device 2, the first on-off valve 17 and the second on-off valve 18. Program, odds for a normal roulette game using the BET screen 51 (number of credits paid out for winning per chip), a program for controlling each satellite 4 and the like.

  On the other hand, the RAM 82 stores the bet information of the chips supplied from each satellite 4, the winning number of the roulette device 2 determined by the projector 32 and the light receiver 33, and data related to the result of the processing executed by the main control CPU 80. Memorize temporarily.

The main control CPU 80 is connected to a first on-off valve 17 and a second on-off valve 18 that adjust the air pressure in the air tubes 15 and 16. And the air compressed by the compressor 14 (refer FIG. 2) is discharged from the 1st discharge port 35 provided in the ball | bowl storage part 23 by opening the 1st on-off valve 17. FIG. Further, by opening the second on-off valve 18, the air compressed by the compressor 14 is discharged from the second discharge port 36 provided in the bank passage 29.
When the player's betting time ends at each satellite 4, that is, when the BET timer graph 59 on the BET screen 51 reaches the rightmost side, the first on-off valve 17 is set to a predetermined time (2 in the first embodiment). Sec). As a result, the ball 11 stored in the ball storage unit 23 at the end of the previous game is rolled in the direction of the bank passage 29 by air pressure.
Subsequently, the second on-off valve 18 is opened to create a layer of air that flows along the bank passage 29 of the roulette wheel 12. Then, the balls 11 rolled into the bank passage by the air pressure from the first discharge port 35 rotate in the bank passage 29 in the clockwise direction in accordance with the air layer flow.
Thereafter, when the second on-off valve 18 is closed when a predetermined time (15 seconds in the first embodiment) has elapsed, the flow of air discharged from the second discharge port 36 is also stopped, and the rotation speed of the ball 11 gradually increases. It weakens, loses centrifugal force, rolls down the slope of the inclined surface 28, and is stored in the ball storage portion 23.

  The main control CPU 80 is connected to a light projector 32 and a light receiver 33 provided in the roulette device 2. As described above, the light projector 32 and the light receiver 33 are provided in each ball storage unit 23, and when the ball 11 enters the ball storage unit 23, the light is blocked and the presence of the ball 11 can be detected. Accordingly, when the ball 11 enters a certain ball storage portion 23, the presence of the ball 11 is detected by the optical sensor including the projector 32 and the light receiver 33 and transmitted to the main control CPU 80. Based on the result, the main control CPU 80 determines the winning number.

  Further, a drive motor 34 for rotating the rotary disk 22 of the roulette wheel 12 is connected to the main control CPU 80 via a motor drive circuit 85. The rotating disk 22 is predetermined in a predetermined direction (for example, clockwise direction) with respect to the frame body 21 immediately after the start of rolling of the ball 11 until the predetermined time elapses after the ball 11 is stored in the ball storage unit 23. The drive motor 34 is controlled to rotate at a speed (for example, 2π [rad / s]).

  Further, a timer 84 for measuring time is connected to the main control CPU 80. The time information of the timer 84 is transmitted to the main control CPU 80, and the main control CPU 80 opens and closes the first on-off valve 17 and the second on-off valve 18 as described later based on the time information of the timer 84.

  As shown in FIG. 11, the ROM 81 stores the payout credit storage area 81 </ b> A in which odds relating to the roulette game using the BET screen 51 are stored, and the opening / closing timings of the first opening / closing valve 17 and the second opening / closing valve 18. A stored opening / closing timing storage area 81B is provided. The odds for each BET area of the BET screen 51 stored in the payout credit storage area 81A are “× 2” to “*” depending on the betting method (“straight up”, “corner bet”, “split bet”, etc.). There is a dividend of “× 36”.

Next, the opening / closing timings of the first opening / closing valve 17 and the second opening / closing valve 18 stored in the opening / closing timing storage area 81B of the ROM 81 will be described with reference to FIG. FIG. 13 is an explanatory diagram showing the opening and closing timing of the first on-off valve and the second on-off valve.
As shown in FIG. 13, when a game is started, first, a betting period in which a player bets chips on each satellite 4 is started. When the betting period ends (the BET timer graph 59 on the BET screen 51 reaches the rightmost side), the main control CPU 80 opens the first on-off valve 17 for a predetermined time (2 seconds in the first embodiment). Subsequently, the second on-off valve 18 is opened to create an annular air layer that flows along the bank passage 29 of the roulette wheel 12 (see FIG. 16). Then, the balls 11 rolled in the direction of the bank passage 29 by the air pressure from the first discharge port 35 rotate the bank passage 29 in the clockwise direction according to the air flow.
Thereafter, when a predetermined time (15 seconds in the first embodiment) elapses, the main control CPU 80 closes the second on-off valve 18. Thereby, the air discharged from the second discharge port 36 stops, and the rotation speed of the ball 11 gradually decreases. The circle drawn by the ball 11 gradually becomes smaller, and finally, the centrifugal force is lost and the slope of the inclined surface 28 rolls down and is stored in the ball storage portion 23. Then, a winning number is determined by an optical sensor including a projector 32 and a light receiver 33, and medals are paid out. Thus, one game is finished. Further, when the game is subsequently started, the satellite 4 betting period is similarly started, and when the betting period ends, the main control CPU 80 opens the first on-off valve 17. The roulette game processing program based on the opening / closing timing of the first opening / closing valve and the second opening / closing valve will be described in detail later with reference to a flowchart (see FIG. 14).

  The RAM 82 also stores a bet information storage area 82A for storing bet information of the player who is currently playing, and a winning number storage area for storing the winning numbers of the roulette wheel 12 determined by the projector 32 and the light receiver 33. 82B is provided. Specifically, the bet information is the BET area designated on the BET screen 51 and the number of chips bet.

  Next, a configuration related to the control system of the satellite 4 connected to the CPU 80 of the main control unit 83 according to the first embodiment will be described with reference to FIG. FIG. 10 is a block diagram schematically showing a satellite control system according to the first embodiment. Note that the ten satellites 4 basically have the same configuration, and the following description will be made by taking one satellite 4 as an example.

  As shown in FIG. 10, the satellite 4 includes a satellite control unit 90 and several peripheral devices. The satellite control unit 90 includes a satellite control CPU 91, a ROM 92, and a RAM 93. The ROM 92 is composed of, for example, a semiconductor memory, and stores programs for realizing basic functions of the satellite 4, various programs necessary for controlling the satellite 4, data tables, and the like. The RAM 93 is a memory for temporarily storing various data calculated by the satellite control CPU 91, the number of credits currently owned by the player, the chip betting status by the player, and the like.

The satellite control CPU 91 is connected to a BET confirmation button 45, a refund button 46, and a help button 47 provided in the control unit 6 (see FIG. 1). The satellite control CPU 91 performs control to execute various corresponding operations based on operation signals output by pressing the buttons. Specifically, various processes are executed based on the input signal supplied from the control unit 6 in response to the input of the player's operation, and the data and programs stored in the ROM 92 and RAM 93, The result is transmitted to the main control CPU 80 of the main control unit 83 described above.
On the other hand, the satellite control CPU 91 receives a command signal from the main control CPU 80, controls peripheral devices constituting the satellite 4, and causes the satellite 4 to advance the roulette game. Further, depending on the content of the process, the satellite control CPU 91 may receive an input signal supplied from the control unit 6 in response to an input of a player's operation, and data and programs stored in the ROM 92 and the RAM 93. Based on the results, various processes are executed, and on the basis of the results, peripheral devices constituting the satellite 4 are controlled, and the roulette game is advanced in the satellite 4. Note that which method is used for processing is set for each processing according to the content of the processing. For example, the medal payout process for the winning number is the former, and the bet operation process on the BET screen 51 by the player corresponds to the latter process.

A hopper 94 is connected to the satellite control CPU 91. In response to a command signal from the satellite control CPU 91, the hopper 94 pays out a predetermined number of medals from the medal payout port 8 (see FIG. 1).
Further, the image display device 7 is connected to the satellite control CPU 91 via the liquid crystal drive circuit 95. In this respect, the liquid crystal driving circuit 95 is configured by a program ROM, an image ROM, an image control CPU, a work RAM, a VDP (video display processor), a video RAM, and the like. The program ROM stores an image control program related to display on the image display device 7 and various selection tables. Further, the image ROM stores, for example, dot data for forming an image displayed on the image display device 7. Also, the image control CPU applies the image display device 7 from the dot data stored in advance in the image ROM according to the image control program stored in advance in the program ROM based on the parameters set by the satellite control CPU 91. The image to be displayed is determined. The work RAM is configured as a temporary storage unit when the image control program is executed by the image control CPU. The VDP forms an image corresponding to the display content determined by the image control CPU and outputs the image to the image display device 7. The video RAM is configured as a temporary storage unit when an image is formed with VDP.

  The touch panel 48 is attached to the front surface of the image display device 7 as described above, and operation information on the touch panel 48 is transmitted to the satellite control CPU 91. On the touch panel 48, a player's chip betting operation is performed on the BET screen 51. Specifically, the operation of the touch panel 48 is performed in the selection of the BET area, the operation of the unit BET button 56, and the like, and the information is transmitted to the satellite control CPU 91. Based on this information, the RAM 93 stores the current player's betting information (the BET area designated on the BET screen 51 and the number of chips betted) as needed. Further, the bet information is transmitted to the main control CPU 80 and stored in the bet information storage area 82A of the RAM 82.

  Furthermore, a sound output circuit 96 and a speaker 9 are connected to the satellite control CPU 91, and the speaker 9 generates various sound effects when performing various effects based on the output signal from the sound output circuit 96. .

  A medal sensor 97 is connected to the satellite control CPU 91. The medal sensor 97 detects a medal inserted from the medal slot 5 (FIG. 1), calculates the inserted medal, and transmits the result to the satellite control CPU 91. Then, the satellite control CPU 91 increases the number of credits of the player stored in the RAM 93 based on the transmitted signal.

  Next, a game processing program in the roulette game machine 1 according to the first embodiment will be described with reference to FIG. FIG. 14 is a flowchart of the roulette game processing program in the roulette game machine 1 according to the first embodiment. 14 are stored in the ROM 81 and the RAM 82 provided in the roulette game machine 1 and executed by the main control CPU 80.

  First, in step (hereinafter abbreviated as S) 1, the main control CPU 80 determines whether or not a medal or money has been inserted by the player. In the roulette game machine 1 according to the first embodiment, when any satellite 4 inserts a medal or money into the medal insertion slot 5, the medal sensor 97 detects that fact and transmits it to the satellite control CPU 91. Thereafter, a medal insertion signal is further sent from the satellite 4 to the main control unit 83. As a result, the main control CPU 80 determines whether a player has inserted a medal or money. If no medal or money is inserted (S1: NO), the process waits until it is inserted. If a medal or money is inserted (S1: YES), the process proceeds to S2. When a medal or money is inserted, the satellite control unit 90 records credit data of an amount corresponding to the number of inserted coins in the RAM 93.

  Further, the BET screen 51 shown in FIG. 8 is displayed on the image display device 7 of the satellite 4 used by the player, and the player can bet chips. Note that other players can participate in the game halfway, and the roulette gaming machine 1 according to the first embodiment can play with up to 10 players.

  Then, a betting period, which is a receiving period during which a player can bet, is started from the time when a player who participates first inserts a medal or money (S2). When the current game is played after the previous game, the betting period starts after the previous game ends. Then, the player who participated in the game can bet his / her chip in the BET area related to the number that he / she expects by operating the touch panel 48 during the betting period (see FIG. 8). Since the specific betting method using the BET screen 51 has already been described, the description thereof is omitted here.

  Next, in S3, it is determined whether or not the betting period has ended. Here, the betting period is displayed by the BET timer graph 59, and the red graph gradually extends to the right side from the start of the betting period (S2). The betting period in the current game ends when it extends to the rightmost side.

  Here, before the betting period ends (S3: NO), the bet is continuously accepted. On the other hand, when the betting period ends (S3: YES), the satellite controller 90 of all satellites 4 terminates the betting. A signal is output, and an image indicating that the betting is completed is displayed on the liquid crystal screen of each satellite 4, and a betting operation on the touch panel 48 is prohibited. Then, the bet information (the designated BET area and the number of chips bet on the designated BET area) made by the player in each satellite 4 is received (S4) and stored in the bet information storage area 82A of the RAM 82.

  Next, the main control CPU 80 executes a lottery process by the roulette device 2 in accordance with the game execution program. First, in S5, the compressor 14 is turned on, and the compressor 14 starts to compress air. Thereafter, the first on-off valve 17 is opened (S6). Here, the first on-off valve 17 is provided in the air tube 15 that conveys the air compressed by the compressor 14 to the first discharge port 35 as described above, and adjusts the air pressure of the air passing through the air tube 15. It is possible to do. When the first on-off valve 17 is opened, discharge of compressed air from the first discharge port 35 is started. As a result, air pressure is applied to the ball 11 stored in any of the ball storage portions 23, and the ball 11 is rolled into the bank passage 29 against the inclination of the inclined surface 28. FIG. 15 is a schematic diagram showing a ball rolling mode of the roulette device in Step 6.

  As shown in FIG. 15, when the first opening / closing valve 17 is opened in S <b> 6, the balls 11 stored in the ball storage portions 23 are caused by the air pressure from the first discharge ports 35 provided in the ball storage portions 23. Is rolled in the bank passage 29 direction (arrow 70 direction).

Next, it is determined whether or not a predetermined time (2 seconds in the first embodiment) has elapsed after the first on-off valve 17 is opened in S7. Here, the passage of time is measured by a timer 84 connected to the main control CPU 80. Then, when the measured value t1 after the first opening / closing valve 17 is opened is less than 2 seconds (S7: NO), the first opening / closing valve 17 is continuously opened.
On the other hand, if the measured value t1 after the opening of the first on-off valve 17 is 2 seconds or longer (S7: YES), the process proceeds to S8.

  In S <b> 8, the main control CPU 80 closes the first on-off valve 17 and stops the discharge of air from the first discharge port 35. Subsequently, in S9, the second on-off valve 18 is opened. Here, the second on-off valve 18 is provided in the air tube 16 that conveys the air compressed by the compressor 14 to the second discharge port 36 as described above, and adjusts the air pressure of the air passing through the air tube 16. It is possible to do. When the second on-off valve 18 is opened, discharge of compressed air from the second discharge port 36 is started. As a result, a layer of air flowing in the clockwise direction along the bank passage 29 is generated, and the ball 11 rolled to the bank passage 29 by S6 performs a rolling motion in a circular orbit according to the discharged air pressure. Start. FIG. 16 is a schematic diagram showing a rolling mode of the ball of the roulette device in Step 9.

  As shown in FIG. 16, when the second on-off valve 18 is opened in S8, the air discharged from the second discharge ports 36 provided in the bank passages 29 along the bank passages 29 in the roulette wheel 12 respectively. Thus, an air flow in the clockwise direction (arrow 71 direction) is formed. Then, the ball 11 that has been rolled toward the bank passage 29 by the air pressure from the first discharge port 35 is changed in the rolling direction to the circumferential direction of the roulette wheel 12 according to the air pressure from the second discharge port 36. (See arrow 72). Further, the ball 11 to which air pressure is applied from the second discharge port 36 is gradually rolled to the outer peripheral edge side of the roulette wheel 12 by centrifugal force, and starts rolling along the bank passage 29 (see arrow 73). . Here, the bank passage 29 is guided against the centrifugal force of the ball 11 that rolls on the roulette wheel 12 and rolls in a circumferential orbit. Further, since the wall portion 31 is formed at the upper end corresponding to the outer peripheral portion so as to be continuous with the bank passage 29, there is no possibility that the ball 11 rotating on the bank passage 29 jumps out of the roulette wheel 12.

Next, it is determined whether or not a predetermined time (15 seconds in the first embodiment) has elapsed after the second on-off valve 18 is opened in S10. Here, the passage of time is measured by a timer 84 connected to the main control CPU 80. Then, when the measured value t2 after the opening of the second on-off valve 18 is less than 15 seconds (S10: NO), the second on-off valve 18 is continuously opened.
On the other hand, when the measured value t2 after the opening of the second on-off valve 18 is 15 seconds or longer (S10: YES), the process proceeds to S11.

In S <b> 11, the main control CPU 80 closes the second on-off valve 18 and stops the discharge of air from the second discharge port 36. Furthermore, in S12, the power of the compressor 14 is turned off, and the compression of air by the compressor 14 is stopped.
By stopping the discharge of air from the second discharge port 36, the ball 11 rolling along the bank passage 29 does not receive the air pressure from the second discharge port 36, and the rotation speed gradually decreases. Centrifugal force decreases. And finally, it rolls down the inclined surface 28 and goes to the inside of the roulette wheel 12 to reach the rotating disk 22 that rotates. FIG. 17 is a schematic diagram showing a ball rolling mode of the roulette device in Step 11.

As shown in FIG. 17, when the second on-off valve 18 is closed in S11, the air discharged from the second discharge ports 36 provided in the bank passages 29 stops and no air pressure is received. The rotation speed of the ball 11 gradually decreases. Then, the ball 11 whose centrifugal force is reduced along with the speed continues to draw a circumferential trajectory while moving gradually inward from the bank passage 29 along the inclination of the inclined surface 28. Eventually, it rolls down the inclined surface 28, goes inward, and reaches the rotating disk 22 (see arrow 74).
Then, the ball 11 that has rolled in the direction of the rotating disk 22 passes through the number display plate 24 on the outer side of the rotating rotating disk 22 and is stored in one of the ball storage units 23, and the ball storage unit 23 in which the balls 11 are stored. A number (any one of “0”, “00”, “1” to “36”) written on the number display board 24 corresponding to the number is the winning number.

  Subsequently, after the ball 11 is stored in the ball storage unit 23, the light projector 32 and the light receiver 33 detect which ball storage unit 23 the ball 11 has dropped, and the main control CPU 80 determines the winning number (“0”). ”,“ 00 ”, or“ 1 ”to“ 36 ”) (S13).

  Further, the main control CPU 80 determines whether or not the chip bet in each satellite 4 is won from the bet information of each satellite 4 received in S4 and the winning number determined in S13. (S14).

Based on the winning determination in S13, it is determined whether or not the chip betted in at least one satellite 4 has been won (S15). If it is determined that the chip is won (S15: YES), the main control CPU 80 executes a payout calculation process (S16). In the payout calculation process, a winning chip is recognized for each satellite 4 and paid out to each satellite 4 using the odds (the number of credits paid out per chip) for the BET area stored in the payout credit storage area 81A of the ROM 81. Calculate the total amount of credit dividends. Subsequently, the process proceeds to S17.
On the other hand, when it is determined that there is no winning chip in all the satellites 4 (S15: NO), the process proceeds to S18.

  In S17, a credit payout process is executed based on the payout calculation process in S16. When paying out credits to the satellite 4, credit data corresponding to the payout amount is output from the main control unit 83 to the satellite control unit 90 of the selected satellite 4. This credit data is added to the RAM 93 of the corresponding satellite 4.

  In S18, it is determined whether or not the game is continuously performed in at least one satellite 4. When the player finishes the game, the player normally presses the refund button 46. When the payout button 46 is pressed, a medal (usually one medal for one credit) according to the credit owned by the current player acquired by the game or the like is paid out from the medal payout exit 8 through the hopper 94. .

When the game is continuously performed in any of the satellites 4 (S18: NO), the process returns to S2 to start the betting period again, and shifts to the next game.
On the other hand, when the game is ended in all the satellites 4 (S18: YES), the roulette game process is ended.

As described above, in the roulette gaming machine 1 according to the first embodiment, the roulette device 2 is provided with the first discharge port 35 for discharging the air compressed by the compressor 14 in the ball storage portion 23 of the roulette wheel 12, and the first discharge port. The ball 11 stored in the ball storage portion 23 is rolled in the direction of the bank passage 29 by the air pressure of the air discharged from the outlet 35 (S6), and the air compressed by the compressor 14 in the circumferential direction of the bank passage 29 is also used. Is provided, and the balls 11 rolled to the bank passage 29 by the air pressure of the air discharged from the second discharge port 36 are rolled along the bank passage 29 in the circumferential direction ( S9), so that the ball 11 is not rolled and the ball 11 is recovered from the roulette wheel 12 without collecting the ball 11 from the roulette wheel 12. It is possible to repeat the housing to Le housing section 23, it does not require a complicated mechanism such as a movable portion or the like and the firing device for collecting the ball. Therefore, the maintenance work is facilitated and the cost of the apparatus can be reduced. Further, since the required depth of the ball storage portion 23 and the required height of the roulette wheel 12 can be reduced, the player can position the ball 11 in any of the ball storage portions 23. The viewing angle β (see FIG. 4) can be confirmed, and the ball checking operation is facilitated, so that the gameability is improved.
Further, since the ball storage portion 23 and the bank passage 29 are continuously formed by one inclined surface 28 rising from the ball storage portion 23 to the bank passage 29 at a predetermined inclination angle, The ball 11 stored in the part 23 can be easily confirmed, and the game performance is improved.
Moreover, since the bank passage 29 has a wall portion 31 continuously provided around the bank passage 29 on the outer peripheral portion, there is a possibility that the balls 11 rolling on the bank passage 29 may jump out of the roulette wheel 12 due to centrifugal force. It is possible to play the game safely.
Furthermore, since the diameter D of the ball 11 is larger than the depth L1 of the ball storage portion 23 when stored in the ball storage portion 23, there is no possibility that the ball 11 will be buried in the ball storage portion 23, and during the game. In addition, the player can easily check the position of the ball 11 stored in the ball storage unit 23.

(Second Embodiment)
Next, a roulette game machine 201 according to the second embodiment will be described with reference to FIGS. In the following description, the same reference numerals as those of the roulette game machine 1 according to the first embodiment in FIGS. 1 to 17 denote the same or corresponding parts as those of the roulette game machine 1 according to the first embodiment. Is.

The schematic configuration of the roulette game machine 201 according to the second embodiment is substantially the same as that of the roulette game machine 1 according to the first embodiment. Various control processes are also substantially the same as the roulette game machine 1 according to the first embodiment.
However, it differs from the roulette game machine 1 according to the first embodiment in the following points.

First, the roulette gaming machine 1 according to the first embodiment is provided at the center of the roulette wheel 12, and the entire rotating disk 22 having the ball storage portion 23 is supported rotatably with respect to the frame body 21. 4 (see FIG. 4), the roulette gaming machine 201 according to the second embodiment has a central fixing portion 222 fixed to the frame body 221 at the central portion of the roulette board 212, and a central fixing portion. An annular rotary movable portion 220 rotatably supported via a cross ball bearing 226 with respect to 222 is disposed, and each ball storage portion 223 is provided on the rotary movable portion 220 (see FIG. 20). ). That is, the difference is that the center portion of the roulette wheel 212 is always fixed during the game, and only the ball storage portion 223 arranged in the circumferential direction is rotated.
Secondly, the roulette gaming machine 1 according to the first embodiment uses the compressed air from the compressor 14 for firing the stored balls 11 to all the ball storage units 23 (38 in the first embodiment). In contrast to the first embodiment, the first discharge port 35 and the detection sensors 32 and 33 for detecting the ball storage portion in which the ball 11 is stored after rolling the ball are provided (see FIG. 5). The roulette game machine 201 according to the invention has one fixed discharge port 243 for discharging compressed air to the central fixed portion 222 fixedly supported at the central portion of the roulette board 212, and three ball detection sensors for detecting the ball 11. A location is provided (see FIG. 19). First, after the ball rolls, the rotation detection unit 244 detects the ball storage unit 223 in which the ball 11 is stored by rotating the rotary movable unit 220, and then detects the front of the fixed discharge port 243. The difference is that the ball 11 in the ball storage unit 223 is fired by rotating the rotary movable unit 220 so that the ball storage unit 223 is positioned and discharging air.

  First, the configuration of the roulette device 202 according to the second embodiment will be described with reference to FIGS. 18 is a perspective view showing a roulette device according to the second embodiment, FIG. 19 is a plan view showing the roulette device according to the second embodiment, and FIG. 20 is an arrow view of the roulette device cut along line BB in FIG. FIG. 21 is an enlarged schematic view showing the vicinity of the ball storage portion of FIG. 20, FIG. 22 is a cross-sectional view of the roulette device taken along line CC in FIG. 19, and FIG. 23 is a second embodiment. It is the perspective view which expanded and showed the ball | bowl storage part vicinity of the roulette device which concerns on this.

  As shown in FIG. 18, the roulette device 202 according to the second embodiment includes a roulette wheel 212 having a rolling area where the ball 11 rolls during the game, and a support for supporting the roulette wheel 212 inside the roulette game machine 201. The base 13, the compressor 14 that takes in ambient air and compresses it to a predetermined pressure, the air tubes 15 and 16 that send the air compressed by the compressor 14, and the air tubes 15 provided at the intermediate points of the air tubes 15 and 16, respectively. , 16 is basically composed of a first on-off valve 17 and a second on-off valve 18 for adjusting the pressure of air flowing through.

  The roulette wheel 212 has a frame 221 fixed to the support base 13, a center fixing part 222 fixedly supported inside the frame 221, and an annular rotation provided around the center fixing part 222. The movable unit 220 is basically configured. A large number (38 in the second embodiment) of concave ball storage portions 223 are formed on the upper surface of the rotationally movable portion 220 in the circumferential direction. The ball storage portion 223 is partitioned by a substantially triangular partition wall 223A (see FIG. 23), and the upper surface of the rotationally movable portion 220 in the outward direction of each ball storage portion 223 corresponds to each ball storage portion 223. Thus, a number display plate 224 on which numbers “0”, “00”, and “1” to “36” as graphic characters are displayed is formed. The rotationally movable portion 220 is rotatably supported by a central fixed portion 222 via a cross ball bearing 226 (see FIG. 24), and a drive motor 234 (see FIG. 20) provided inside the roulette device 2. Thus, a predetermined speed (for example, 2π) in a predetermined direction (for example, clockwise direction) with respect to the frame body 221 from when the preparation for launching the ball 11 is started until the predetermined time elapses after the ball 11 is stored in the ball storage unit 223. [Rad / s]). In particular, when the ball 11 is fired after the end of the betting period, the ball storage portion 223 in which the ball 11 is currently stored is positioned in front of a fixed discharge port 243 (described later) fixed to the center fixing portion 222. The rotating movable unit 220 is rotated. On the other hand, when detecting the ball storage portion 223 in which the ball 11 is stored after the end of the ball rolling, the rotationally movable portion 220 passes through the front of a ball detection sensor 244 described later fixed to the center fixing portion 222. Rotate. The specific rotation operation of the rotary movable unit 220 will be described in detail later.

  Here, the rolling region where the ball 11 actually rolls on the roulette wheel 212 includes the first inclined surface 228 </ b> A formed by the ball storage portion 223 and the number display plate 224 on the rotation movable portion 220, and the frame body 221. It consists of one inclined surface 228 having a predetermined angle (15 degrees in the second embodiment) formed by the second inclined surface 228B formed on the inner peripheral edge side. The inclined surface 228 is inclined so as to rise from the center direction of the roulette wheel 212 toward the outer peripheral direction, and a ball storage portion 223 and a bank passage 229 described later are continuously formed via the inclined surface 228.

  A bank passage 229 is provided around the outer peripheral edge of the frame 221. The bank passage 229 is a passage that guides the ball 11 against the centrifugal force of the ball 11 that rolls on the roulette wheel 212 and rolls the ball 11 in a circular orbit. Further, the bank passage 229 is formed endlessly with respect to the roulette wheel 212 by a guide wall 230 erected in the vertical direction, and further, a wall portion is continuous with the bank passage 229 at an upper end corresponding to an outer peripheral portion thereof. 231 is formed. The wall portion 231 is a member that urges the ball 11 that rotates on the bank passage 229 inward so as not to jump out of the roulette wheel 212.

Then, the ball 11 to which acceleration force is applied by air discharged from the fixed discharge port 243 and the second discharge port 36, which will be described later, gradually increases in speed and rotates along the bank passage 229. On the other hand, when the discharge of air from the second discharge port 36 is stopped, the rotation speed of the ball 11 decreases and the centrifugal force is lost, and the ball 11 rolls down the inclined surface 228 toward the inside of the roulette wheel 212 and rotates. Part 220 is reached.
Then, the ball 11 that has rolled to the rotationally movable part 220 passes through the number display plate 224 of the rotationally movable part 220 to be rotated and is stored in one of the ball storage parts 223, and the ball storage part 223 in which the balls 11 are stored. The number written on the number display plate 224 corresponding to the number is the winning number.

Further, as shown in FIG. 21, the depth L2 of the ball storage portion 223 with respect to the inclined surface 228 is formed to be shallower than the diameter D of the ball 11.
As described above, the ball storage portion 223 is a space for storing the balls 11 that are partitioned into a total of 38 pieces in the circumferential direction by the partition wall 223A. Since the depth L2 of the ball storage portion 223 is configured to be shallower than the diameter D of the ball 11, when the ball 11 is stored in the ball storage portion 223, as shown in FIG. There is no possibility that the ball 11 is buried in the portion 223, and the player can easily confirm the position of the ball 11 stored in the ball storage portion 223 during the game. Therefore, gameability is improved.
Further, since the ball storage portion 223 and the bank passage 229 are continuously formed by one inclined surface 228 that rises from the ball storage portion 223 to the bank passage 229 at a predetermined inclination angle, It becomes easy to confirm the ball 11 stored in the portion 223.

  Next, various sensors such as the fixed discharge port 243 and the ball detection sensor 244 provided in the central fixing portion 222 of the roulette wheel 212 will be described with reference to FIGS. 20, 22, and 23. Here, unlike the roulette device 2 according to the first embodiment, the roulette device 202 according to the second embodiment is a fixed discharge port 243 that discharges compressed air from the compressor 14 to the central fixed portion 222 that is not rotationally driven during the game. And a ball detection sensor 244 for detecting the ball storage portion 223 in which the ball 11 is stored.

As shown in FIGS. 19 and 20, the fixed discharge port 243 is fixedly supported by a fixed plate 227 on the outer peripheral edge of the central fixed portion 222, particularly facing the rotationally movable portion 220. Then, air compressed to a predetermined pressure (for example, 1 Mpa) is conveyed to the roulette wheel 212 through the air tube 15 by the compressor 14 (see FIG. 18) provided below the roulette device 202.
On the other hand, a circular air passage hole 235 is formed on the inner wall 237 that forms each ball storage portion 223 together with the partition wall 223A. In the second embodiment, 38 ball storage portions 223 corresponding to the numbers “0”, “00”, “1” to “36” are formed, and therefore the air passage holes 235 are formed at 38 locations. Has been. Then, as shown in FIG. 23, in the ball storage portion 223 (the ball storage portion with the number “21” in FIG. 23) located in front of the fixed discharge port 243, the air discharged from the fixed discharge port 243 is air passing hole 235. The light is emitted toward the bank passage 229 provided on the outer peripheral edge of the roulette wheel 212 via the ball storage portion 223. Then, the ball 11 accommodated in the ball accommodating portion 223 starts rolling in the direction of the bank passage 229 against the inclination of the inclined surface 228 by the air pressure of the discharged air.

  Further, as shown in FIGS. 19 and 22, the ball detection sensor 244 is fixedly supported by a fixing plate 227 on the outer peripheral edge of the center fixing portion 222, particularly facing the rotationally movable portion 220. Here, the ball detection sensor 244 is a reflection type optical sensor, and includes a light emitting element that emits infrared light and a light receiving element that receives light. When an obstacle exists within a predetermined distance, it is possible to detect the presence and position of the obstacle. Accordingly, it is possible to detect the ball 11 stored in a predetermined position (for example, at a distance of 3 cm) in the ball storage unit 223 positioned in front of the ball detection sensor 244 through the air passage hole 235. The ball detection sensor 244 may be a transmissive optical sensor. In this case, a light receiving element is installed at the center fixing portion 222 and a light emitting element is installed at a position of the bank passage 229 facing the light receiving element. And when the ball | bowl 11 exists in the ball | bowl storage part 223 located between a light emitting element and a light receiving element, it becomes possible to detect it.

  In addition to the ball detection sensor 244, the center fixing portion 222 is provided with an origin sensor 257 and a rotation sensor 258. Here, the origin sensor 257 and the rotation sensor 258 are fixedly supported by a fixed plate 227 on the outer periphery facing the rotation movable unit 220, similarly to the ball detection sensor 244 and the fixed discharge port 243.

The origin sensor 257 is a sensor that detects the position of the ball storage section 223 located in front of the origin sensor 257 relative to the origin (reference point). The rotation sensor 258 is a sensor that detects whether or not the rotary movable unit 220 is rotating.
Specifically, while the origin sensor 257 detects that the rotation movable unit 220 is rotating by the rotation sensor 258, the origin sensor 257 is opposite to the origin sensor 257 on the back side of the inner wall 237 of each ball storage unit 223. By detecting the unevenness of an identification plate (not shown) having an uneven shape attached to the side), the ball storage portion 223 currently positioned in front of the origin sensor 257 corresponds to the origin “00”. It is always detected which position is relative to the attached ball storage portion 223. For example, at the time shown in FIG. 19, the ball storage unit 223 located in front of the origin sensor 257 (the ball storage unit associated with “35”) moves rightward from the ball storage unit 223 associated with “00”. It is detected that the ball storage unit 223 is located at the 16th position.

  Therefore, according to the origin sensor 257, at the timing when the ball 11 is detected by the ball detection sensor 244, the ball storage section 223 located in front of the origin sensor 257 is moved from the ball storage section 223 associated with “00”. It is possible to detect the position. Based on the detection result, it is possible to calculate the position of the ball storage unit 223 where the ball 11 is detected by the ball detection sensor 244 from the ball storage unit 223 associated with “00”. . Thereby, the numbers (“0”, “00”, “1” to “36”) associated with the ball storage unit 223 in which the ball 11 is detected, that is, the winning number can be specified (FIG. 27). S118). The origin (reference point) need not be the ball storage unit 223 associated with “00”, and may be another ball storage unit 223.

  Further, when the ball 11 is fired at the start of the game, the winning number of the previous game and the position of the ball storage unit 223 located in front of the origin sensor 257 from the ball storage unit 223 associated with “00”. It is possible to determine whether or not the ball storage portion 223 in which the ball 11 is stored is at a position in front of the fixed discharge port 243 based on the detection result of whether the ball 11 is present. Then, by controlling the drive motor 234 based on the determination result, the ball storage portion 223 in which the ball 11 is stored is positioned in front of the fixed discharge port 243, and the ball 11 can be fired (S106 in FIG. 27). To S108).

As described above, in the roulette game machine 201 according to the second embodiment, after the ball 11 is stored in the ball storage unit 223, all the ball storage units 223 are rotated by rotating the rotary movable unit 220 at least 1/3 round. One of the ball detection sensors 244 passes in front of. Then, the detection result of the origin sensor 257 at the timing when the ball 11 is detected is transmitted to a main control CPU 80 (see FIG. 25) described later. Based on the result, the main control CPU 80 determines the winning number.
Further, when the ball is fired, the drive motor 234 described later is controlled so that the fixed discharge port 243 is positioned in front of the ball storage unit 223 of the winning number in the previous game, and air is discharged from the fixed discharge port 243. Thus, the ball 11 can be launched from the ball storage portion 223. Therefore, without collecting the ball 11 from the roulette wheel 212, force is applied to the ball 11 by the air pressure of the air discharged from the fixed discharge port 243 and the second discharge port 36, and rolling and storage in the ball storage unit 223 are performed. Can be repeated. Therefore, maintenance work is facilitated and the cost of the apparatus can be reduced without requiring a complicated mechanism such as a movable part for collecting the ball 11 or a launching device. The configurations of the second discharge port 36 and the rotation air pipe 39 are the same as those of the roulette device 2 according to the first embodiment, and detailed description thereof is omitted.

  Next, the rotation mechanism of the rotation movable part 220 with respect to the center fixed part 222 of the roulette wheel 212 will be described with reference to FIGS. Here, FIG. 24 is a schematic view showing the cross ball bearing 226 that rotatably supports the rotary movable portion 220 with respect to the central fixed portion 222 at a predetermined position in the roulette device according to the second embodiment. .

  As shown in FIG. 20, a drive motor 234 is fixed to the bottom plate 221 </ b> A of the frame body 221. Here, the drive motor 234 is a stepping motor that can rotate in units of steps determined without feedback by giving a pulse signal. Therefore, the rotation angle and the rotation speed are determined by the number and period of the pulse signals given to the drive motor 234, and further, the rotation angle at that time is held and stopped by stopping the pulse signal.

  A driving roller 247 is attached to the driving motor 234 via a driving shaft 246, and the driving roller 247 is in contact with the side surface 220 </ b> A of the rotary movable unit 220. Accordingly, when the drive motor 234 is driven, the drive roller 247 is also rotated along with the rotation of the drive motor 234, and the rotationally movable portion 220 is rotated relative to the central fixed portion 222 due to friction with the drive roller 247. The driving roller 247 is housed in a roller case 248 having a “U” shape. Further, the roller case 248 is fixed in the direction of the side surface 220 </ b> A by an urging member 249 provided on the outer peripheral side of the driving roller 247. It is energized by force. Therefore, the driving roller 247 and the side surface 220A of the rotary movable unit 220 are always in contact with each other based on an appropriate pressure, and there is no possibility that the driving roller 247 is subjected to an excessive load or runs idle.

  20 and 24, the fixed inner wall portion 250 of the central fixed portion 222 and the movable inner wall portion 251 of the rotary movable portion 220 facing the fixed side inner wall portion 250 are connected by a cross ball bearing 226. ing.

  Here, the cross ball bearing 226 is an annular member having a substantially square cross section, and bearings 252 are attached to 30 to 40 locations on each of the four surfaces thereof. Thereby, the movable side inner wall portion 251 can freely move with respect to the fixed side inner wall portion 250 fixed to the frame body 221, and the rotation movable portion 220 is rotatably supported with respect to the central fixed portion 222. The Rukoto.

  Therefore, based on the rotation direction and rotation angle of the drive motor 234 driven by the pulse signal, the rotation movable unit 220 can be rotated by a predetermined angle with respect to the central fixed unit 222, and accordingly, the fixed discharge port 243. The ball storage portion 223 positioned in front of the ball detection sensor 244 is changed to an arbitrary ball storage portion 223. Thereby, it is possible to detect the ball storage portion 223 in which the ball 11 is stored and to fire the ball 11 stored therein. The drive motor 234 is connected to the main control CPU 80 via a motor drive circuit 255 (see FIG. 25), and the drive thereof is controlled as described later based on a program stored in a ROM or the like.

Next, a configuration related to the control system of the roulette game machine 201 according to the second embodiment will be described with reference to FIG. FIG. 25 is a block diagram schematically showing a control system of the roulette game machine according to the second embodiment.
As shown in FIG. 25, the roulette game machine 201 includes a main control unit 83 including a main control CPU 80, a ROM 81, and a RAM 82, a roulette device 202 connected to the main control unit 83, and ten satellites 4 (FIG. 25). 1), and a first on-off valve 17 and a second on-off valve 18. The control system of the satellite 4 is the same as that of the roulette game machine 1 according to the first embodiment, and the details are omitted.

  The main control CPU 80 performs various processes based on the input signals supplied from the satellites 4 and the data and programs stored in the ROM 81 and the RAM 82, and sends command signals to the satellites 4 based on the results. Is transmitted to control each satellite 4 to advance the game. Further, the drive motor 234 is driven and the ball detection sensor 244 (see FIG. 22) provided in the roulette device 202 is controlled to determine the winning number of the ball storage unit 23 where the ball 11 has fallen. Based on the winning number obtained and the bet information transmitted from each satellite 4, the winning determination of the betted chip is performed, and the number of credits to be paid out in each satellite 4 is calculated.

  The ROM 81 is composed of, for example, a semiconductor memory, and controls a program for realizing basic functions of the roulette game machine 201, each device in the roulette device 202, the first on-off valve 17 and the second on-off valve 18. Program for controlling the drive motor 234, odds for a normal roulette game using the BET screen 51 (the number of credits paid out for winning per chip), a program for controlling each satellite 4 and the like Remember.

  On the other hand, the RAM 82 temporarily stores the bet information of the chip supplied from each satellite 4, the winning number of the roulette device 2 determined by the ball detection sensor 244, data related to the result of the processing executed by the main control CPU 80, and the like. To remember.

The main control CPU 80 is connected to a first on-off valve 17 and a second on-off valve 18 that adjust the air pressure in the air tubes 15 and 16. And the air compressed by the compressor 14 (refer FIG. 18) is discharged from the fixed discharge port 243 provided in the ball | bowl storage part 223 by opening the 1st on-off valve 17. FIG. Further, by opening the second on-off valve 18, the air compressed by the compressor 14 is discharged from the second discharge port 36 provided in the bank passage 229.
Then, when the player's betting time ends in each satellite 4, that is, when the BET timer graph 59 on the BET screen 51 reaches the rightmost side, the driving motor 234 is driven to obtain the previous winning number. The ball storage portion 223, that is, the ball storage portion 223 in which the ball 11 is stored, is positioned in front of the fixed discharge port 243. Then, the first on-off valve 17 is opened for a predetermined time (2 seconds in the second embodiment). As a result, the ball 11 stored in the ball storage unit 223 at the end of the previous game is rolled in the direction of the bank passage 229 by air pressure.
Subsequently, the second on-off valve 18 is opened, and a layer of air flowing along the bank passage 229 of the roulette wheel 212 is created. Then, the balls 11 rolled into the bank passage by the air pressure from the fixed discharge port 243 rotate the bank passage 229 in the clockwise direction in accordance with the air layer flow.
Thereafter, when the second on-off valve 18 is closed when a predetermined time (15 seconds in the second embodiment) has elapsed, the flow of air discharged from the second discharge port 36 is also stopped, and the rotation speed of the ball 11 gradually increases. It weakens and loses centrifugal force, rolls down the slope of the inclined surface 228, and is stored in the ball storage portion 223.

  The main control CPU 80 is connected to a ball detection sensor 244, an origin sensor 257, and a rotation sensor 258 provided in the roulette device 2. As described above, the ball detection sensors 244 are provided at the three locations of the central fixing portion 222, and are associated with the presence of the ball 11 when the ball 11 is stored in the ball storage portion 223 located in front. The number can be detected. In addition, the origin sensor 257 can detect a relative position of the ball storage unit 223 located in front with respect to the origin (ball storage unit associated with “00”). Further, the rotation sensor 258 can detect the presence or absence of rotation of the rotary movable unit 220. Then, the detection result of each sensor is transmitted to the main control CPU 80, so that the main control CPU 80 determines the winning number.

  Further, the main control CPU 80 is connected to a drive motor 234 that drives the rotationally movable portion 220 via the motor drive circuit 255. When a motor drive signal is output from the main control CPU 80 to the motor drive circuit 255, the drive motor 234 is given a pulse signal from the motor drive circuit 255, and based on the pulse signal, a predetermined number of rotations in a predetermined rotation direction. Driven by rotation. As a result, the rotationally movable portion 220 is rotated by a predetermined angle (for example, 45 degrees) in a predetermined direction (for example, clockwise direction) with respect to the central fixed portion 222 and the frame body 221, and an arbitrary ball is positioned at the front position of the fixed discharge port 243. The storage part 223 can be arranged.

  Further, a timer 84 for measuring time is connected to the main control CPU 80. The time information of the timer 84 is transmitted to the main control CPU 80, and the main control CPU 80 opens and closes the first on-off valve 17 and the second on-off valve 18 as described later based on the time information of the timer 84.

Next, the opening / closing timing of the first opening / closing valve 17 and the second opening / closing valve 18 and the drive control of the drive motor 234 stored in the ROM 81 will be described with reference to FIG. FIG. 26 is an explanatory diagram showing the opening / closing timings of the first on-off valve and the second on-off valve and the drive control of the drive motor 234.
As shown in FIG. 26, when the game is started, first, a betting period in which a player bets chips at each satellite 4 is started. When the betting period ends (the BET timer graph 59 on the BET screen 51 reaches the rightmost side), the ball storage unit 223 in which the ball 11 is stored based on the previous winning number and the detection result of the origin sensor 257. And the drive motor 234 is driven at a predetermined first rotation speed until the ball storage portion 223 is positioned in front of the fixed discharge port 243, and the rotation movable portion 220 is driven at a predetermined rotation speed (for example, 0. 0). 2π [rad / s]). Thereafter, the main control CPU 80 opens the first on-off valve 17 for a predetermined time (2 seconds in the second embodiment). Subsequently, the second on-off valve 18 is opened to create an annular air layer that flows along the bank passage 229 of the roulette wheel 212 (see FIG. 16). Then, the balls 11 rolled in the direction of the bank passage 229 by the air pressure from the fixed discharge port 243 rotate the bank passage 229 in the clockwise direction according to the air flow. At the same time, the drive motor 234 is driven at a predetermined second rotational speed, and the rotationally movable part 220 is rotated with respect to the rotationally movable part 220 at a predetermined rotational speed (for example, 2π [rad / s]).
Thereafter, when a predetermined time (15 seconds in the second embodiment) elapses, the main control CPU 80 closes the second on-off valve 18. Thereby, the air discharged from the second discharge port 36 stops, and the rotation speed of the ball 11 gradually decreases. The circle drawn by the ball 11 gradually becomes smaller, and finally, the centrifugal force is lost to roll down the slope of the inclined surface 228 and fit in the ball storage portion 223. And after closing the 2nd on-off valve 18, the rotational speed of the drive motor 234 is attenuate | damped gradually, and the rotational speed of the rotation movable part 220 is made slow. In the meantime, the winning number is determined by each of the ball detection sensor 244, the origin sensor 257, and the rotation sensor 258. Further, medals are paid out according to the determined winning number. Thus, one game is finished. Further, when the game is subsequently started, the satellite 4 betting period is similarly started, and when the betting period ends, the main control CPU 80 opens the first on-off valve 17. The roulette game processing program based on the opening / closing of the first opening / closing valve and the second opening / closing valve and the drive control of the drive motor 234 will be described in detail later with reference to a flowchart (see FIG. 27).

  Next, a game processing program in the roulette game machine 201 according to the second embodiment will be described with reference to FIG. FIG. 27 is a flowchart of a roulette game processing program in the roulette game machine 201 according to the second embodiment. Each program shown in the flowchart in FIG. 27 is stored in the ROM 81 or RAM 82 provided in the roulette game machine 201 and is executed by the main control CPU 80.

  First, in step 101, the main control CPU 80 determines whether or not a player has inserted medals or money. In the roulette game machine 1 according to the second embodiment, when any satellite 4 inserts a medal or money into the medal insertion slot 5, the medal sensor 97 detects that fact and transmits it to the satellite control CPU 91. Thereafter, a medal insertion signal is further sent from the satellite 4 to the main control unit 83. As a result, the main control CPU 80 determines whether a player has inserted a medal or money. If no medal or money is inserted (S101: NO), the process waits until it is inserted. If a medal or money is inserted (S101: YES), the process proceeds to S102. When a medal or money is inserted, the satellite control unit 90 records credit data of an amount corresponding to the number of inserted coins in the RAM 93.

  Further, the BET screen 51 shown in FIG. 8 is displayed on the image display device 7 of the satellite 4 used by the player, and the player can bet chips. Note that other players can participate in the game halfway, and the roulette gaming machine 1 according to the second embodiment can play with up to 10 players.

  Then, a betting period, which is a receiving period during which the player can bet, is started from the time when the player who first participates inserts a medal or money (S102). When the current game is played after the previous game, the betting period starts after the previous game ends. Then, the player who participated in the game can bet his / her chip in the BET area related to the number that he / she expects by operating the touch panel 48 during the betting period (see FIG. 8). Since the specific betting method using the BET screen 51 has already been described, the description thereof is omitted here.

  Next, in S103, it is determined whether or not the betting period has ended. Here, the betting period is displayed by the BET timer graph 59, and the red graph gradually extends to the right side from the start of the betting period (S102). The betting period in the current game ends when it extends to the rightmost side.

  Here, before the betting period ends (S103: NO), the bet is continuously accepted. On the other hand, when the betting period ends (S103: YES), the satellite controller 90 of all satellites 4 terminates the betting. A signal is output, and an image indicating that the betting is completed is displayed on the liquid crystal screen of each satellite 4, and a betting operation on the touch panel 48 is prohibited. Then, the bet information (designated BET area and the number of chips bet on the designated BET area) made by the player in each satellite 4 is received (S104) and stored in the bet information storage area 82A of the RAM 82.

  Next, the main control CPU 80 executes a lottery process by the roulette device 2 in accordance with the game execution program. Specifically, first, the winning numbers in the previous game (“1” to “36”, “0”, “00”) are read from the winning number storage area 82B of the RAM 82 (S105). Then, the drive motor 234 is driven at a predetermined first rotation speed, and the rotary movable unit 220 is rotated at a predetermined rotation speed (for example, 0.2π [rad / s]) with respect to the central fixed portion 222 (S106). .

  At that time, the rotation sensor 258 detects the rotation of the rotary movable unit 220, and the origin sensor 257 provided in the center fixing unit 222 stores the previous winning number acquired in S105, that is, the ball 11 at the present time. The position at which the ball storage portion 223 is located relative to the fixed discharge port 243 is specified. In S <b> 107, based on the specific position, it is determined whether or not the ball storage unit 223 storing the ball 11 is positioned in front of the fixed discharge port 243 by the rotation of the rotary movable unit 220.

  As a result, when it is determined that the ball storage portion 223 in which the ball 11 is stored is located in front of the fixed discharge port 243 (S107: YES), the drive of the drive motor 234 is stopped (S108). On the other hand, when it is determined that the ball storage portion 223 in which the ball 11 is stored is not located in front of the fixed discharge port 243 (S107: NO), the drive motor 234 is continuously driven.

  Here, FIG. 28 is a schematic diagram showing a rotation mode of the rotary movable unit 220 of the roulette device 202 in steps 106 to S108. As shown in FIG. 28, the ball storage portion 223 in which the ball 11 is stored (the ball storage portion associated with the number “29” in FIG. 28) is the eleventh in the left direction with respect to the fixed discharge port 243. In the case of the ball storage unit 223 positioned, the rotation movable unit 220 is rotated clockwise. Then, as a result of rotating by a predetermined angle (in the right direction, 11 ball storage portions in FIG. 28), when the ball storage portion 223 storing the balls 11 is positioned in front of the fixed discharge port 243, the rotationally movable portion 220. Stop rotating.

  In step S109, the compressor 14 is turned on, and the compressor 14 starts to compress air. Thereafter, the first on-off valve 17 is opened (S110). Here, the first on-off valve 17 is provided in the air tube 15 that conveys the air compressed by the compressor 14 to the fixed discharge port 243 as described above, and adjusts the air pressure of the air passing through the air tube 15. It is possible. When the first on-off valve 17 is opened, discharge of compressed air from the fixed discharge port 243 is started. Accordingly, air pressure is applied to the ball 11 stored in the ball storage portion 223 via the air passage hole 235, and the ball 11 is rolled to the bank passage 229 against the inclination of the inclined surface 228. FIG. 29 is a schematic diagram showing a rolling mode of the ball of the roulette device in Step 110. FIG.

  As shown in FIG. 29, when the first on-off valve 17 is opened in S110, the ball 11 stored in the ball storage portion 223 is banked by the air pressure from the fixed discharge port 243 provided in the central fixing portion 222. Rolled in the direction of the passage 229 (the direction of the arrow 75).

Next, it is determined whether or not a predetermined time (2 seconds in the second embodiment) has elapsed after the first on-off valve 17 is opened in S111. Here, the passage of time is measured by a timer 84 connected to the main control CPU 80. And when measured value t1 after the 1st opening-and-closing valve 17 was opened is less than 2 seconds (S111: NO), the 1st opening-and-closing valve 17 is opened continuously.
On the other hand, when the measured value t1 after the opening of the first on-off valve 17 is 2 seconds or longer (S111: YES), the process proceeds to S112.

  In S112, the main control CPU 80 closes the first on-off valve 17 and stops the discharge of air from the fixed discharge port 243. Subsequently, in S113, the second on-off valve 18 is opened. Here, the second on-off valve 18 is provided in the air tube 16 that conveys the air compressed by the compressor 14 to the second discharge port 36 as described above, and adjusts the air pressure of the air passing through the air tube 16. It is possible to do. When the second on-off valve 18 is opened, discharge of compressed air from the second discharge port 36 is started. Thereby, a layer of air flowing in the clockwise direction along the bank passage 229 is generated, and the ball 11 rolled to the bank passage 229 by S6 is the same as in the roulette game machine 1 according to the first embodiment. Rolling in a circular orbit is started according to the discharged air pressure (see FIG. 16).

  Next, in S114, the drive motor 234 is driven at a predetermined second rotation speed, and the rotary movable unit 220 is rotated at a predetermined rotation speed (for example, 2π [rad / s]) with respect to the central fixed portion 222 ( S114). At the same time, the rotation sensor 258 detects the rotation of the rotary movable unit 220, and the origin sensor 257 provided in the center fixing unit 222 causes the ball storage unit 223 positioned in front of the origin sensor to correspond to the origin (“00”). It is always detected which position is relative to the ball storage portion).

In S115, it is determined whether a predetermined time (15 seconds in the second embodiment) has elapsed after the second on-off valve 18 is opened. Here, the passage of time is measured by a timer 84 connected to the main control CPU 80. Then, when the measured value t2 after the opening of the second on-off valve 18 is less than 15 seconds (S115: NO), the second on-off valve 18 is continuously opened.
On the other hand, when the measured value t2 after the opening of the second on-off valve 18 is 15 seconds or longer (S115: YES), the process proceeds to S116.

In S <b> 116, the main control CPU 80 closes the second on-off valve 18 and stops the discharge of air from the second discharge port 36. Further, in S117, the power source of the compressor 14 is turned off, and the compression of air by the compressor 14 is stopped.
By stopping the discharge of air from the second discharge port 36, the ball 11 rolling along the bank passage 229 does not receive the air pressure from the second discharge port 36, and the rotation speed gradually decreases. Centrifugal force decreases. And finally, it rolls down the inclined surface 228 and goes to the inside of the roulette wheel 212 to reach the rotating movable portion 220 that rotates.

  Subsequently, in S118, the rotational speed of the drive motor 234 is gradually attenuated, and the ball 11 stored in the ball storage unit 223 is detected by the ball detection sensor 244. Then, from the detection result of the origin sensor 257 at the timing when the ball is detected by the ball detection sensor 244, the numbers (“0”, “00”, “1”) associated with the ball storage unit 223 in which the ball 11 is detected. To “36”), that is, the winning number is specified (S118).

  Further, the main control CPU 80 stops driving the drive motor 234 (S119), and bets on each satellite 4 from the bet information of each satellite 4 received in S104 and the winning number determined in S118. It is determined whether or not the chip is won (S120).

Then, based on the winning determination in S120, it is determined whether or not a chip bet in at least one satellite 4 has been won (S121). When it is determined that the chip is won (S121: YES), the main control CPU 80 executes payout calculation processing (S122). In the payout calculation process, a winning chip is recognized for each satellite 4 and paid out to each satellite 4 using the odds (the number of credits paid out per chip) for the BET area stored in the payout credit storage area 81A of the ROM 81. Calculate the total amount of credit dividends. Subsequently, the process proceeds to S123.
On the other hand, when it is determined that there is no winning chip in all the satellites 4 (S121: NO), the process proceeds to S124.

  In S123, a credit payout process is executed based on the payout calculation process in S122. When paying out credits to the satellite 4, credit data corresponding to the payout amount is output from the main control unit 83 to the satellite control unit 90 of the selected satellite 4. This credit data is added to the RAM 93 of the corresponding satellite 4.

  In S124, it is determined whether or not the game is continuously performed in at least one satellite 4. When the player finishes the game, the player normally presses the refund button 46. When the payout button 46 is pressed, a medal (usually one medal for one credit) according to the credit owned by the current player acquired by the game or the like is paid out from the medal payout exit 8 through the hopper 94. .

When the game is continuously performed in any of the satellites 4 (S124: NO), the process returns to S102, the betting period is started again, and the next game is started.
On the other hand, when the game is finished in all the satellites 4 (S124: YES), the roulette game process is finished.

As described above, in the roulette game machine 1 according to the second embodiment, the fixed discharge for discharging the air compressed by the compressor 14 to the center fixing portion 222 fixedly supported at the center of the roulette wheel 212 in the roulette device 2. Various sensors for specifying the winning number such as the outlet 243 and the ball detection sensor 244 are provided, and the rotation movable unit 220 is rotated so that the ball storage unit 223 storing the ball 11 is first positioned in front of the fixed discharge port 243. (S106 to S108), the balls 11 stored in the ball storage portion 223 are rolled in the direction of the bank passage 229 by the air pressure of the air discharged from the fixed discharge port 243 (S110), and the circumferential direction of the bank passage 29 Similarly, a second discharge port 36 for discharging the air compressed by the compressor 14 is provided. Since the ball 11 rolled to the bank passage 229 by the air pressure discharged from the second discharge port 36 is rolled in the circumferential direction along the bank passage 229 (S113), the ball 11 from above the roulette wheel 212 is used. Without being collected, it is possible to repeatedly roll the ball 11 on the roulette wheel 212 and store it in the ball storage portion 223, and to move a complicated portion such as a movable portion for collecting the ball 11 or a launching device. No mechanism is required. Therefore, the maintenance work is facilitated and the cost of the apparatus can be reduced. In addition, since the required depth of the ball storage portion 223 and the required height of the roulette wheel 212 can be reduced, the player can position the ball 11 in any of the ball storage portions 223. The viewing angle γ (see FIG. 20) can be confirmed, and the ball checking operation is facilitated, so that the gameability is improved.
Furthermore, by fixing the center fixing portion 222 and rotating only the rotary movable portion 220, the number of driving locations of the roulette wheel 212 can be reduced, and the burden on the driving motor 234 can be reduced. In addition, the number of the fixed discharge ports 243 can be a minimum number (1 in the second embodiment) regardless of the number of the ball storage units 223, so that the structure of the roulette device 202 is further simplified. Is possible.
Further, since the ball storage portion 223 and the bank passage 229 are continuously formed by one inclined surface 228 that rises from the ball storage portion 223 to the bank passage 229 at a predetermined inclination angle, The ball 11 stored in the portion 223 can be easily confirmed, and the game performance is improved.
Further, since the bank passage 229 has a wall portion 231 provided continuously around the bank passage 229 on the outer peripheral portion, there is a possibility that the balls 11 rolling on the bank passage 229 may jump out of the roulette wheel 212 due to centrifugal force. It is possible to play the game safely.
Furthermore, since the diameter D of the ball 11 is larger than the depth L2 of the ball storage portion 223 when stored in the ball storage portion 223, there is no possibility that the ball 11 is buried in the ball storage portion 223, and the game is in progress. In addition, the player can easily confirm the position of the ball 11 stored in the ball storage unit 223.

In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
For example, in the first embodiment and the second embodiment, the ball 11 that rolls in the bank passage direction by the air pressure from the first discharge port 35 or the fixed discharge port 243 is changed to the bank passage by the air pressure from the second discharge port 36. 29 and 229 are rolled so as to draw a circumferential trajectory, but the frame bodies 21 and 221 may be rotated without providing the second discharge port 36. When the frame bodies 21 and 221 are rotated, the ball 11 on the frame body also starts to rotate in the circumferential direction, and rolls along the bank passages 29 and 229 by the centrifugal force due to the rotation.

  In the first embodiment and the second embodiment, a force is applied to the ball 11 in the roulette wheel based on the compressed air pressure. A permanent magnet is built in the ball 11, and the first discharge port 35, the ball 11 may be rolled by a magnetic force by providing an electromagnet at the positions of the fixed discharge port 243 and the second discharge port 36.

  In the first embodiment, air is simultaneously discharged from all the ball storage portions 23 through the launching air pipe 38. However, the balls 11 are stored in any of the ball storage portions 23 by the projector 32 and the light receiver 33. The air may be discharged only from the first discharge port 35 provided in the storage groove.

  In the second embodiment, the air passage hole 235 through which the air from the fixed discharge port 243 passes is a circular hole, but the shape is such that the air discharged from the fixed discharge port 243 is the ball storage portion. Any structure may be used as long as it passes through 223, and it may be formed in a groove formed in a horizontal direction or a vertical direction, or in a notch shape.
