  The entrance determination means 110 determines whether or not a game ball has entered each winning opening. When receiving the start winning information, the winning determination means 110 determines that the game ball has won the start opening 62, and when receiving the big winning opening winning information, determines that the game ball has won the big winning opening 66, and the general winning is obtained. When the information is received, it is determined that the game ball has won the general winning opening 72. When receiving the passage information, the ball entering determination unit 110 determines that the game ball has passed through the operation port 68.

  The success / failure lottery means 112 acquires a random number value as a success / failure lottery value in order to determine whether or not to shift from the normal game to the special game when the game ball enters the start port 62. For example, the success / failure lottery value is acquired from a range of 0 to 65535. The “random number” in the present application may not be a mathematically generated random number, but may be a pseudo-random number generated by a hardware random number, a software random number, or the like. The success / failure lottery means 112 holds a success / failure table referred to in the determination of success / failure. In the success / failure table, a determination result of winning or losing is associated with a success / failure lottery value, and the success / failure probability is determined according to the associated winning range setting. The success / failure lottery means 112 executes the special symbol lottery by referring to the success / failure table and determining whether or not the success / failure lottery value is a win.

  The symbol determination means 114 determines the stop symbol and the variation pattern to be displayed on the special symbol display device 61 and the effect display device 60 according to the lottery result by the success / failure lottery means 112. The stop symbol is a symbol to be displayed at the end of symbol variation. The symbol determination means 114 holds a symbol range table to be referred to in order to determine a special symbol stop symbol. A special symbol range table is held as a table for determining the special symbol 202. In the special symbol range table, the correspondence between the special symbol 202 represented by the numbers “0” to “9” and the symbol determination lottery value is defined. The symbol determination unit 114 holds a pattern determination table to be referred to in order to determine the variation pattern of the special symbol 202.

  The symbol determination unit 114 acquires a symbol determination lottery value for determining the special symbol 202, refers to the special symbol range table, and determines the special symbol 202 according to the determination result of the success / failure lottery unit 112 and the symbol determination lottery value. Determine the stop pattern. The symbol determination unit 114 refers to the pattern determination table, and selects one of a plurality of variation patterns in accordance with the determination result of the success / failure lottery unit 112. The symbol determination unit 114 sends data indicating the determined stop symbol and variation pattern to the main display control unit 118 and the effect determination unit 132.

  The symbol determination unit 114 stores a plurality of types of variation patterns in which variation modes from the variation start to the stop when the special symbol 202 is variably displayed. Multiple types of variation patterns have various variation times. That is, for each variation pattern, a variation display time is defined for each pattern as an end condition of the symbol variation, and the variation of the special symbol 202 is stopped when the variation display time elapses.

  The symbol determination means 114 also determines the stop symbol of the normal symbol 204 by the normal symbol lottery. There are two types of stop symbols for the normal symbol 204: a winning symbol and a missing symbol. When the game ball passes through the operating port 68, the symbol determination means 114 acquires a lottery random number for determining the normal symbol 204, and determines a stop symbol of the normal symbol 204 according to the lottery random number. When the stop symbol of the normal symbol 204 is a winning symbol, the opening / closing control means 124 expands the normal electric accessory at the start port 62 for a predetermined time.

  The hold control means 116 holds the winning / losing lottery value acquired by the winning / failing lottery means 112 as a holding ball. The success / failure lottery value is accumulated until the number of holds reaches a predetermined upper limit. The upper limit of the number of holds is 4. The hold control means 116 holds the upper limit of four as a result of the normal symbol lottery.

  The main display control means 118 displays the special symbol 202 variably. The main display control means 118 transmits a change start command and a change stop command to the effect display control means 134 at the timing for starting and stopping the change display of the special symbol 202. This guarantees synchronization between the change display of the special symbol 202 and the moving image display of the decorative symbol 200. The main display control means 118 also displays the normal symbol 204 in a variable manner. The special game control means 120 controls the execution of the special game.

  The opening / closing control means 124 controls the opening / closing of the ordinary electric accessory at the start opening 62 and the special winning opening 66. When the normal symbol hits and stops at the symbol, the opening / closing control means 124 sends an opening instruction to the ordinary electric accessory solenoid 76 to open the start port 62. Further, the opening / closing control means 124 sends an opening instruction to the special winning opening solenoid 80 during the special game, and opens the special winning opening 66.

  The pattern storage means 130 of the sub-board 104 holds a plurality of types of effect patterns of the decorative design 200. In each effect pattern, a moving image display time is set for each pattern as an end condition of the moving image display, and the moving image display is stopped when the moving image display time elapses. The effect determining unit 132 selects the effect pattern and the decorative symbol 200 at the time of stop according to the variation time determined by the symbol determining unit 114, the stop symbol, and the special symbol lottery result.

  In the moving image display of the decorative symbol 200, three symbol variable display modes are shown, and the display mode when each symbol is stopped is determined according to the result of the special symbol lottery. For example, when the special symbol 202 indicates “7” or “2” as a stop symbol and indicates a transition to a special game, the decorative symbol 200 having three symbols such as “777” and “222” is stopped and displayed. Is done. When the determination result by the winning / failing lottery means 112 indicates that the game does not shift to the special game, the combination of the three symbols such as “312” and “946” is stopped and displayed. However, if the determination result is that the game does not shift to a special game, and an effect pattern indicating a loss of reach is selected, only one symbol such as “191” or “727” is provided. The stop is displayed in the combination that is not. The effect determining unit 132 sends the combination information and the information of the effect pattern when the symbols included in the decorative symbol 200 are stopped to the effect display control unit 134.

  The effect display control means 134 displays the decorative symbol 200 as a moving image in accordance with the selected effect pattern. The effect display control means 134 also controls effect processing such as lighting and extinguishing of the game effect lamp 90 and voice output from the speaker 18. The movable accessory control means 133 drives the movable accessory 25 according to the selected effect pattern.

The game balls rolling on the rolling guide surfaces 316, 318, and 324 collide with the protrusions 340 and change the direction of rolling or jump up.

  Below the rolling guide surfaces 316, 318, and 324, the rolling effect control board 350 is embedded so that the rolling effect control board 350 is substantially parallel to the rolling guide surfaces 316, 318, and 324. In FIG. 4, the rolling effect control board 350 is indicated by a broken line. As will be described later, the rolling effect control board 350 executes a visual effect by blinking of the game effect lamp 90f in accordance with the position of the game ball rolling on the rolling guide surface 316, 318 or 324.

It should be noted that the coloring effect in the game effect lamp 90c is not limited to a specific emission color such as an LED, but may be changed by changing the emission color by, for example, arranging a filter. Further, the other game effect lamps 90 are also composed of LEDs and lamps, and are configured to emit light for performing a desired effect. Furthermore, the movable accessory 25 can perform a dynamic effect by moving and vibrating in the vertical direction and the horizontal direction, for example, by a drive mechanism including a motor and a link (not shown).

  FIG. 6 is a diagram showing a configuration of the rolling effect control board 350. On the rolling effect control board 350, a rolling effect control IC 352, rolling sensors 354a to 354c, and rolling effect LEDs 356a to 356h are mounted. Hereinafter, the rolling sensors 354a to 354c are collectively referred to as “rolling sensor 354”, and the rolling effect LEDs 356a to 356h are collectively referred to as “rolling effect LED 356”. The rolling effect control board 350 is configured by mounting a rolling effect control IC 352 and a rolling sensor 354 on the board of the rolling effect LED 356. Each of the rolling sensor 354 and the rolling effect LED 356 is arranged at a predetermined interval. In this embodiment, three rolling sensors 354 and eight rolling effect LEDs 356 are mounted. However, the number of rolling sensors 354 and rolling effect LEDs 356 is not limited to this, and may be one or more. .

The rolling sensor 354 is a magnetic sensor that detects the position of the game ball rolling on the rolling guide surface 316, 318, or 324 by omnidirectional magnetism. Specifically, the rolling sensor 354 includes a vertical direction and a horizontal direction of the rolling effect control board 350 shown in FIG. 6, that is, a direction horizontal to the surface of the rolling effect control board 350, and a height direction, ie, rolling effect control. The position of the game ball is detected by detecting magnetism in a direction perpendicular to the surface of the substrate 350. The rolling effect control IC 352 functions as a means for controlling the effect by the game effect lamp 90f in the effect display control means 134. Specifically, based on the detection result by rolling sensor 354, rolling effect control IC 352 causes rolling effect LED 356 at the position detected by rolling sensor 354 among rolling effect LEDs 356a to 356h to emit light.
Note that the position detection accuracy can be increased by increasing the number of rolling sensors 354 mounted on the rolling effect control board 350 and detecting the position of the game ball in more detail.

  Hereinafter, game effects using the rolling effect control board 350 will be described. In FIG. 6, A1 and A2 indicated by broken lines roll on the rolling guide surfaces 316, 318, or 324 when the rolling effect control board 350 is installed below the rolling guide surfaces 316, 318, and 324. Indicates the position of the game ball. For example, when the game ball passes A1, the rolling sensors 354a to 354c detect the position of the game ball by magnetism in all directions. The rolling effect control IC 352 calculates the position of the game ball by combining the detection results of the rolling sensors 354a to 354c, and detects that the game ball is at the position A1. Then, the rolling effect control IC 352 causes the rolling effect LED 356 at the detection position to emit light. Here, since the rolling effect LED 356 closest to the detection position A1 is the rolling effect LED 356d, the rolling effect control IC 352 causes the rolling effect LED 356d to emit light.

  Further, when the game ball rolls on the rolling guide surfaces 316, 318 and 324 while passing through the A2 while colliding with the protrusion 340, the rolling sensors 354a to 354c detect the position of the game ball by magnetism in all directions. . The rolling effect control IC 352 combines the detection results of the rolling sensors 354a to 354c to calculate the position of the game ball and detects that the game ball is at the position A2. Here, since the rolling effect LED 356 closest to the detection position A2 is the rolling effect LED 356f, the rolling effect control IC 352 causes the rolling effect LED 356f to emit light.

  As described above, the rolling effect LED 356 emits light based on the position of the game ball detected by the rolling sensor 354, so that the rolling effect LED 356 is on the rolling guide surfaces 316, 318, and 324. Lights up to follow the movement of the game ball rolling. This makes it possible for the player to entertain a novel effect by the game effect lamp 90f according to the change in the movement of the game ball. Further, the game ball rolls on the rolling guide surfaces 316, 318, and 324 while colliding with the protrusion 340 and changing direction or jumping up. By turning on the rolling effect LED 356 in such a manner as to follow the game ball that rolls in a direction that is difficult to predict, the player can enjoy a more innovative effect.

  When it is attempted to detect the position of a game ball using a unitized sensor as in the prior art, the position where the sensor can be placed is limited due to space issues because the shape is determined in advance as a unit. Therefore, it is difficult to arrange the sensor in a limited space such as below the rolling guide surfaces 316, 318 and 324 described above. Even if it can be arranged, it is difficult to secure a space for arranging the LED substrate in the vicinity of the sensor. In other words, it is difficult to realize an effect of turning on the LED in such a manner that the unitized sensor is used to follow the game ball as described above.

  On the other hand, in this embodiment, since the rolling sensor 354 is not unitized, the installation position is hardly restricted and the sensor can be installed relatively freely. By arranging the sensor at an optimum position for detecting the position of the game ball, the position of the game ball can be detected with high accuracy, so that a novel effect corresponding to the movement of the game ball can be realized. Further, since the rolling sensor 354 can be mounted on the substrate of the rolling effect LED 356 as in the present embodiment, both the rolling sensor 354 and the rolling effect LED 356 are arranged in a limited position in a limited space. It is also possible. Furthermore, according to the present embodiment, the rolling sensor 354 is not unitized, so that the cost can be reduced as compared with the case where the unitized sensor is used.

  The present invention has been described based on the embodiments. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are within the scope of the present invention. is there.

  In this embodiment, the rolling effect control board 350 is disposed below the rolling guide surfaces 316, 318, and 324. However, as a modification, the rolling effect control board 350 is disposed in the warp introduction port 70 and the drop guide passage 70a. May be. In this case, the rolling effect control board 350 is installed so as to be substantially parallel to the bottom and side surfaces of the warp introduction port 70, the side surface of the drop guide passage 70a, and the like. In this modification, the rolling effect control IC 352 turns on the rolling effect LED 356 at the detection position of the game ball passing through the warp introduction port 70 and the drop guide passage 70a. As a result, it is possible to realize a novel effect in which the rolling effect LED 356 lights up following the movement of the game ball passing through the warp introduction port 70 and the drop guide passage 70a.

  In this embodiment, the rolling effect control IC 352 lights the rolling effect LED 356 corresponding to the movement of the game ball rolling on the rolling guide surfaces 316, 318, and 324. However, as a modification, the rolling effect control 352 The IC 352 may cause the rolling effect LED 356 to emit light with brightness according to the height of the jumping up of the game ball that has hit the protrusion 340 and jumped up. In this case, the rolling sensor 354 detects the position of the game ball that has jumped up. The rolling effect control IC 352 causes the rolling effect LED 356 disposed closest to the position of the game ball to emit light with a brightness proportional to the height of the jump, for example. Accordingly, it is possible to realize a novel effect in which the rolling effect LED 356 is lit so that the height of the game ball jumping up is expressed by brightness while following the movement of the game ball.

  In the present embodiment, the game is produced by the light emission of the rolling effect LED 356 according to the position of the game ball, but as a modification, the effect by the image display of the effect display device 60 is executed according to the position of the game ball. Also good. In this case, the rolling effect control IC 352 controls the effect display device 60 so as to display an image having contents corresponding to the position of the game ball detected by the rolling sensor 354. Also according to this modification, it is possible to realize a novel effect by displaying images according to the movement and position of the game ball.
