However, the detection methods of the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the count switch 23 and the third winning confirmation switch 23a are shown in this embodiment. For example, if the detection method is different between the first and second start port switches 14a and 15a and the count switch 23 and the first to third winning confirmation switches 14b, 15b and 23a, for example, Photo sensors are used as the start port switches 14a and 15a and the count switch 23, and the first to third prize winning confirmation switches 14b and 15 , It may be used proximity switch as 23a. In this case, based on the detection results of the first and second start port switches 14a and 15a and the count switch 23, which are photosensors, special symbol variation display and prize ball payout processing are executed, and the first to third winning prizes which are proximity switches. The detection results of the confirmation switches 14b, 15b, and 23a are used only for the determination of the abnormal winning of the first starting winning port 13a, the second starting winning port 13b, and the big winning port. For example, instead of a proximity switch or an optical photosensor that is an electromagnetic switch, the first and second start port switches 14a and 15a and the count switch 23 or the first to third prize confirmation switches 14b, 15b, and 23a are used. Alternatively, a mechanical switch (such as a micro switch) may be used.

  Further, in this embodiment, the first and second start port switches 14a and 15a count switch 23 that trigger the execution of the special symbol change display and the prize ball payout process are the first to third prizes used for the determination of the abnormal winning. Although provided on the upstream side of the confirmation switches 14b, 15b, 23a, it may be provided on the downstream side of the switch used for the determination of the abnormal winning.

  Then, the game control microcomputer 1560 uses the first start port switch based on the detection signal input from the first start port switch 14a (proximity switch) and the detection signal input from the first winning confirmation switch 14b (photo sensor). When it is determined that the difference between the number of game balls detected at 14a and the number of game balls detected at the first winning confirmation switch 14b exceeds a predetermined threshold (in this example, 15 or more) As an error, it is determined that an abnormal winning to the first start winning opening 13a has occurred. The game detected by the second start port switch 15a based on the detection signal input from the second start port switch 15a (proximity switch) and the detection signal input from the second winning confirmation switch 15b (photo sensor). When it is determined that the difference between the number of balls and the number of game balls detected by the second winning confirmation switch 15b exceeds a predetermined threshold (in this example, 15 or more), a second error is generated as a predetermined error. It is determined that an abnormal winning to the winning opening 13b has occurred. In addition, based on the detection signal input from the count switch 23 (proximity switch) and the detection signal input from the third winning confirmation switch 23a (photo sensor), the number of game balls detected by the count switch 23 and the third winning prize are determined. If it is determined that the difference from the number of game balls detected by the confirmation switch 23a exceeds a predetermined threshold (in this example, 5 or more), an abnormal winning at the big winning opening occurs as a predetermined error. It is determined that

  In this way, the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the count switch 23 and the third winning confirmation switch 23a are of different detection methods. By configuring the sensor (in this example, a proximity switch and a photo sensor), the actual number of winnings to the first starting winning port 13a, the second starting winning port 13b, and the big winning port using, for example, electromagnetic waves is actually When an illegal act that causes recognition to be greater than the number of winnings is made, there is a difference between the number of game balls detected by the proximity switch and the number of game balls detected by the photo switch, thereby controlling the game. Since the microcomputer 1560 determines that an abnormal winning has occurred when the number of difference balls exceeds a predetermined threshold, it is possible to take a certain measure against illegal acts.

  The game area 7 is provided with decorative members 25L and 25R having a plurality of decorative LEDs 25a that emit light in accordance with the gaming state, and an outlet 26 for collecting the game balls that have not won a prize is provided at the bottom.

  Decorative members 25L and 25R having decorative LEDs 25a blinking and displayed during the game are provided around the left and right sides of the game area 7, and there is an out port 26 for collecting the game balls that have not won a prize. An effect device 500 having a movable part 800 provided at an upper portion inside the stage frame decoration 11 so as to be movable up and down between a raised position above the effect display device 9 and a lowered position superimposed on the front surface of the effect display device 9. Is provided. Further, the effect display device 9 is surrounded by a stage frame decoration 11 that decorates the periphery of the display screen, and a light emitting decoration section 605 that emits light by stage frame decoration LEDs 61 and 62 described later is provided above the stage frame decoration 11. (See FIG. 6) is formed.

  Four speakers 27 that emit sound effects are provided on the left, right, top, and bottom of the outside of the game area 7. On the outer periphery of the game area 7, a top frame LED 28a, a left frame LED 28b, and a right frame LED 28c are provided. The top frame LED 28a, the left frame LED 28b, the right frame LED 28c, and the decoration LED 25a are examples of a decoration light emitter provided in the gaming machine.

  Although not shown in FIGS. 1 and 2, a prize ball lamp that is turned on during the prize ball payout is provided in the vicinity of the left frame LED 28 b, and when the supply ball is cut in the vicinity of the top frame LED 28 a. A ball-out lamp that is lit is provided. Note that the award ball lamp and the out-of-ball lamp are controlled to be turned on by the effect control microcomputer mounted on the effect control board when the award ball is being paid out or when the out-of-ball is detected. Further, although not shown in particular, a prepaid card unit (hereinafter referred to as “card unit”) 50 that enables lending a ball by inserting a prepaid card is installed adjacent to the pachinko gaming machine 1. .

  A game ball launched from the ball striking device by the player's operation enters the game area 7 through the hit ball rail, and then descends the game area 7. When the game ball enters the first start winning port 13a and is detected by the first start port switch 14a, if the variable display of the first special symbol can be started (for example, the variable display of the special symbol ends, 1), the first special symbol display 8a starts variable display (variation) of the first special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. In other words, the variable display of the first special symbol and the effect symbol corresponds to winning in the first start winning opening 13a. If the variable display of the first special symbol cannot be started, the first reserved memory number is increased by 1 on the condition that the first reserved memory number has not reached the upper limit value.

  When the game ball enters the second start winning port 13b and is detected by the second start port switch 15a, if the variable display of the second special symbol can be started (for example, the special symbol variable display ends, 2), the second special symbol display 8b starts variable display (variation) of the second special symbol, and the effect display device 9 starts variable display of the effect symbol (decoration symbol). Is done. That is, the variable display of the second special symbol and the effect symbol corresponds to winning in the second start winning opening 13b. If the variable display of the second special symbol cannot be started, the second reserved memory number is increased by 1 on condition that the second reserved memory number has not reached the upper limit value.

  The variable display of the first special symbol on the first special symbol display 8a and the variable display of the second special symbol on the second special symbol display 8b are stopped when a certain time has elapsed. If the special symbol (stop symbol) at the time of stoppage is a big hit symbol (specific display result), it will be “big hit”, and the special symbol (stop symbol) at the time of stop will be different from the big hit symbol (predetermined display result) Is “small hit”, and if the special symbol at the time of stoppage (stop symbol) is stopped and displayed, a special symbol different from the big hit symbol and the small hit symbol is “lost”.

  After the variable display result in the special figure game becomes “big hit”, the game is controlled to the big hit gaming state as a specific gaming state in which a round advantageous to the player (also referred to as “round game”) is executed a predetermined number of times. Further, after the variable display result in the special figure game becomes “small hit”, the game is controlled to the small hit game state different from the big hit game state.

  In this embodiment, when the big win symbol corresponding to “non-probability change” or “probability change A” in the special figure game is stopped and displayed, the first big win state (15 rounds) as the multi-round specific game state is displayed. (Big hit state). In the big hit gaming state (usually 15 round big hit state), the special winning prize ball device 20 has a predetermined winning period (for example, 29.5 seconds) or a predetermined number (for example, eight) winning balls. During the period until the occurrence of the round, the round is performed to change the special variable winning ball apparatus 20 to the first state (open state) advantageous to the player by opening the special winning opening. In this way, the special prize opening door that has opened the special prize opening during the round is received by receiving the game ball falling on the surface of the game board 6, and then the special prize opening is closed, so that the special variable prize ball is closed. The device 20 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the 15 round big hit state, the number of executions of the round, which is the open cycle of the big prize opening, becomes the first round number (for example, “15”). A game in the 15 round big hit state in which the number of round executions is “15” is also referred to as a 15-time open game. In such a 15 round big hit state, every time a game ball wins a big winning opening, 15 balls (prize balls) are obtained. The 15 round round big hit state is also referred to as a first specific gaming state.

  When the big hit symbol corresponding to “probability change B” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the second big hit state (high-speed 15 round big hit state) as the multi-round specific gaming state. In the second big hit state, the special prize winning ball device 20 has a big winning opening door in a second period (for example, 0.5 seconds) shorter than the first period in the first big hit state or a predetermined number (for example, three) of winnings. The round that changes the special variable winning ball apparatus 20 to the first state (open state) advantageous to the player is performed by opening the grand prize opening in the period until the ball is generated. In this way, the special prize opening door that has opened the special prize opening during the round is received by receiving the game ball falling on the surface of the game board 6, and then the special prize opening is closed, so that the special variable prize ball is closed. The device 20 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the second big hit state, the number of executions of the round, which is the opening cycle of the big prize opening, becomes the second round number (for example, “15”).

  In such a second big hit state, 15 game balls (prize balls) can be obtained if a game ball wins the big winning opening, but the opening period of the big winning opening is the second period (0.5 seconds). It is very short. For this reason, the second big hit state is a big hit gaming state in which a ball (prize ball) cannot be obtained substantially. The second big hit state is also referred to as a second specific gaming state. Further, the second big hit state may be one in which the number of round executions is smaller than that in the first big hit state. That is, in the second big hit state, the period in which the big prize opening is changed to the open state in each round is a second period shorter than the first period in the first big hit state, and the number of round executions is the first big hit state. It may be at least one of the second number of rounds less than the first number of rounds.

  In addition, after the first jackpot state is ended based on the fact that the jackpot symbol corresponding to “non-probable change” is stopped and displayed as a confirmed special symbol in the special figure game, it is compared with the normal state as one of the special gaming states. The time is controlled to be in a time-short state in which time-shortening control (short-time control) is performed in which the variable symbol display time (special-figure variation time) is shortened in the special figure game. Here, the normal state is a normal game state as a game state different from a specific game state such as a big hit game state, a probability change state, and a short time state, and an initial setting state of the pachinko gaming machine 1 (for example, a system reset is performed). As in the case where the initialization process is performed after the power is turned on, the same control is performed. If the time-short state is terminated when any of the conditions of the special game is executed a predetermined number of times (for example, 100 times) and the variable display result is “big hit” is satisfied first, Good. Thus, like the big hit symbol special symbol corresponding to “non-probable change”, the big hit symbol controlled to the short-time state after the first big hit state based on being stopped and displayed as the confirmed special symbol in the special symbol game is This is called a non-probable big hit symbol (also referred to as “normal big hit symbol”). Further, the fact that the non-probable variable big hit symbol among the big hit symbols is stopped and displayed and the variable display result becomes “big hit” is called “non-probable big hit” (also referred to as “normal big hit”).

  The jackpot symbol corresponding to “probability variation B” is displayed after the first big hit state is ended based on the fact that the jackpot symbol corresponding to “probability variation A” is stopped and displayed as a confirmed special symbol in the special symbol game. After the second big hit state is ended based on the fact that it is stopped and displayed as a confirmed special symbol in the game, the special figure variation time is shortened as one of the special game states different from the short-time state, for example, compared with the normal state. Along with the time-shortening control, the state is controlled to a probability variation state (high probability state) in which probability variation control (probability variation control) is continuously performed. In this probabilistic state, the variable display result of each special figure game and decorative design is improved so that the probability that the variable display result will be “big hit” and further controlled to the big hit gaming state will be higher than in the normal state and the short-time state. To do. Such a probability change state continues until the next variable display result is a “big hit”, regardless of the number of executions of the special game.

  Like the jackpot symbol corresponding to such “probability change A”, the jackpot symbol controlled to the probability change state after the first jackpot state based on being stopped and displayed as the confirmed special symbol in the special figure game is the probability change jackpot symbol. It is called. In addition, like the jackpot symbol corresponding to “probability change B”, the jackpot symbol controlled to the probability change state after the jackpot game state based on being stopped and displayed as the confirmed special symbol in the special figure game is the sudden hit bonus symbol. It is called. In addition, the probability variation big hit symbol out of the big hit symbol is stopped and displayed and the variable display result becomes “big hit” is called “probable big hit”. The fact that the sudden hit symbol is stopped and displayed and the variable display result is “big hit” is called “surprise big hit” (also referred to as “surprise big hit”). These jackpot symbols are arbitrary. For example, in order to prevent the player from recognizing the jackpot type, the jackpot symbol may not be a number but may be a predetermined symbol or the like. .

  After the special symbol corresponding to “small hit” is stopped and displayed as the confirmed special symbol in the special symbol game, the small hit game state is controlled. In this small hit game state, similarly to the second big hit state, a variable winning operation is performed in the special variable winning ball apparatus 20 to change the big winning opening to the first state (open state) advantageous to the player. That is, in the small hit gaming state, for example, the operation of setting the special variable winning ball device 20 to the first state (open state) over the second period is the second number {the number of executions equal to the second number of rounds (in this example, 15 It is repeatedly executed until it reaches (time)}. In the small hit gaming state, as in the second big hit state, the period during which the special variable winning ball apparatus 20 is in the first state is the second period, and the number of executions of the operation in the first state is the second. Control may be performed so that at least one of the number of times is performed. After the small hit gaming state ends, the gaming state is not changed, and the game state before the variable display result becomes “small hit” is continuously controlled. However, if the number of executions of the special figure game in the special gaming state has reached a predetermined number when the special figure game with the variable display result of “small hit” is executed, after the end of the small hit gaming state, The special gaming state may end and return to the normal state. A game in the small hit gaming state in which the number of times that the special variable winning ball apparatus 20 is set to the first state by the variable winning operation is “15” is also referred to as a 15-time open game, similar to the game in the second big hit state. When the winning ball device provided separately from the special variable winning ball device 20 in each round in the second big hit state is changed to the first state, the same as in the second big hit state even in the small hit gaming state In the aspect, the winning ball apparatus may be changed to the first state.

  In the probabilistic state and the short time state, the normal symbol display unit 10 controls the normal symbol in the normal symbol game so that the variation time of the normal symbol (ordinary symbol variation time) is shorter than that in the normal state. Control to improve the probability that the display result is “per normal figure” than in the normal state, and tilt control of the movable blade piece in the variable winning ball apparatus 15 based on the fact that the variable display result is “per normal figure”. The game ball can easily pass (enter) the second start winning opening 13b, such as control for making the tilt control time to be performed longer than that in the normal state, and control for increasing the number of tilts than in the normal state. Control that is advantageous to the player is performed by increasing the possibility that the start condition is satisfied. It should be noted that any one of these controls may be performed in the probability variation state or the short time state, or a plurality of controls may be performed in combination. As described above, the control that facilitates the entry of the game ball into the second start winning opening 13b in the probability change state or the short time state is also referred to as high release control. When the high opening control is performed, the frequency at which the second start winning opening 13b is in the expanded opening state is higher than when the high opening control is not performed. As a result, the second start condition for executing the special figure game using the second special figure in the second special symbol display 8b is easily established, and the special figure game can be executed frequently. In addition, the time until the variable display result becomes “big hit” is shortened. Therefore, in the probability variation state and the short time state, it becomes easier to enter the big hit gaming state than in the normal state. The period during which the high opening control can be executed is also referred to as a high opening control period, and this period may be the same as the period during which the gaming state in the pachinko gaming machine 1 is controlled to either the certain change state or the short-time state. . Further, it is also said that the gaming state is in the high base during the high opening control period. On the other hand, when it is not the high opening control period, it is said that the gaming state is in the low base. The short-time state in this embodiment is a gaming state also referred to as a low-probability high-base state, and the normal state is a gaming state also referred to as a low-probability low-base state, which is a probabilistic state that is not a high release control period. The latent probability changing state is a gaming state also called a high probability low base state.

  In this embodiment, after the end of the second big hit state based on the “probability big hit” corresponding to “probability change B” in the normal state, only the probability change control is performed, and the time-shortening control and the high opening control are performed. The process proceeds to the second probability variation control (latent probability variation state) that is not performed. Further, after the end of the second big hit state based on the fact that the “probable big hit” is made in the probability change state, the state shifts to the first probability change state where the time-shortening control and the high opening control are performed together with the probability change control.

  As described above, the probability variation state includes not only the time variation control and the high release control are performed together with the probability variation control but also the probability variation control only and the time reduction control and the high release control are not performed (latency probability variation). It may be. In addition, for example, after the first big hit state based on the fact that the variable display result in the special figure game is “probable big hit”, the first positive change state (high-speed control and high-open control are performed together with the positive change control (high When the number of executions of the special figure game reaches a predetermined number of times (for example, 70 times) without the special figure display result being “big hit”, the probability variation control is continued. However, the control may be performed in a second certain change state (also referred to as a highly accurate low base state) that is not performed after the time-shortening control or the high opening control is finished.

  Further, in this embodiment, after the second big hit state is ended based on the fact that the variable display result in the special game is “surprise big hit” in the probability changing state, the second probability changing state (latent probability changing state) is reached. Although the transition was made, not only the probability change state but also the first probability change even after the end of the second big hit state based on the fact that the variable display result in the special game is “abrupt big hit” when in the short time state You may make it transfer to a state. Alternatively, after the first big hit state based on the “probable big hit” is finished, it is controlled to the first positive change state until the special figure display result becomes “big hit” again, while the second big hit state based on the “surprise big hit” is controlled. After the completion, the process shifts to the first certain change state, and when the number of executions of the special figure game reaches a predetermined number without causing the special figure display result to be “big hit”, the second certain change state is entered. Also good. While the short-time control and the high-open control are started and ended simultaneously (interlocked), the start and end of the probability variation control is not necessarily linked to the start and end of the short-time control and high-open control. May be.

  In the “left”, “middle”, and “right” decorative symbol display areas provided in the effect display device 9, the special symbol game using the first special symbol and the second special symbol in the first special symbol display 8a. Corresponding to the start of one of the special figure games using the second special figure on the display unit 8b, the variable display (variation display) of the decorative symbols is started. In the period from the start of variable display of decorative symbols to the end of variable display due to the stop display of the fixed decorative symbols in the “left”, “middle”, and “right” decorative symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state refers to a decorative pattern (“reach” which has not been temporarily stopped yet when the decorative pattern temporarily stopped displayed in the display area of the effect display device 9 forms a part of the jackpot combination. "Varying symbols") is a display state in which the variation continues, or a display state in which all or part of the decorative symbols change synchronously while constituting all or part of the jackpot combination. is there. Specifically, a part of the “left”, “middle”, and “right” decorative symbol display areas (for example, “left” and “right” decorative symbol display areas) constitutes a predetermined jackpot combination. In a remaining decorative symbol display area (for example, a “medium” decorative symbol display area, etc.) that has not yet been temporarily stopped when a decorative symbol (for example, a decorative symbol indicating the alphanumeric character “7”) is temporarily stopped. The display state in which the decorative symbols are changing, or all or part of the “left”, “middle”, and “right” decorative symbol display areas are synchronized while the decorative symbols constitute all or part of the jackpot combination. The display state is fluctuating.

The game control microcomputer 1560 further includes a random number circuit 53 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 1560, the CPU 56 executes control in accordance with the program stored in the ROM 54. Therefore, the game control microcomputer 1560 (or CPU 56) executes (or performs processing) hereinafter. Specifically, the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31.

  The game control microcomputer 1560 has a built-in random number circuit 53. The random number circuit 53 is a hardware circuit that is used to generate a random number for determination for determining whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 53 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 53 is a hardware circuit that is used to generate a random number for determination for determining whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 53 updates numerical data in accordance with a set update rule within a numerical range in which an initial value (for example, 0) and an upper limit value (for example, 65535) are set, and starts at a random timing Based on the fact that the winning time is the reading (extraction) of the numerical data, it has a random number generation function in which the numerical data to be read becomes a random value.

  The random number circuit 53 has a numeric data update range selection / setting function (initial value selection / setting function and upper limit selection / setting function), numeric data update rule selection / setting function, and numeric data update rule selection. It has various functions such as a switching function. With such a function, the randomness of the generated random numbers can be improved.

  Further, the game control microcomputer 1560 has a function of setting an initial value of numerical data updated by the random number circuit 53. For example, a predetermined calculation is performed using the ID number of the game control microcomputer 1560 (an ID number assigned to each product of the game control microcomputer 1560) stored in a predetermined storage area such as the ROM 54. The numerical data obtained by the execution is set as the initial value of the numerical data updated by the random number circuit 53. By performing such processing, the randomness of the random number generated by the random number circuit 53 can be further improved.

  The game control microcomputer 1560 reads the numerical data as random R from the random number circuit 53 when a start winning to the first start port switch 14a or the second start port switch 15a occurs, and starts to change the special symbol and the effect symbol Sometimes it is determined whether or not to make a big hit display result as a specific display result based on the random R, that is, whether or not to make a big hit. Then, when it is determined to be a big hit, the gaming state is shifted to a big hit gaming state as a specific gaming state advantageous to the player.

  In addition, the game control microcomputer 1560 is used to input / output (transmit / receive) signals to / from the payout control board 37 (the payout control microcomputer) and the effect control board 80 (the effect control microcomputer) by serial communication. A serial communication circuit 52 is incorporated. The payout control microcomputer and the effect control microcomputer also have a serial communication circuit (not shown) for inputting / outputting signals with the game control microcomputer 1560 through serial communication.

  The RAM 55 is a backup RAM as a non-volatile storage means, part or all of which is backed up by a backup power supply created on the power supply board. That is, even if the power supply to the gaming machine is stopped, a part or all of the contents of the RAM 55 is stored for a predetermined period (until the capacitor as the backup power supply is discharged and the backup power supply cannot be supplied). In particular, at least data corresponding to the game state, that is, the control state of the game control means (such as the value of the special symbol process flag and the pending storage number counter) and data indicating the number of unpaid prize balls (specifically, prize balls described later) The value of the command output counter) is stored in the backup RAM. The data corresponding to the control state of the game control means is data necessary for restoring the control state before the occurrence of a power failure or the like based on the data when the power is restored after a power failure or the like occurs. Further, data corresponding to the control state and data indicating the number of unpaid prize balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal from the power supply board is input to the reset terminal of the game control microcomputer 1560. A reset circuit for generating a reset signal supplied to the game control microcomputer 1560 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 1560 and the like become operable, and when the reset signal becomes low level, the game control microcomputer 1560 and the like become inoperative. Therefore, an allowable signal that allows the operation of the game control microcomputer 1560 or the like is output during a period when the reset signal is at a high level, and a game control microcomputer when the reset signal is at a low level. An operation stop signal for stopping the operation of 1560 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Furthermore, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 1560. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). Instead of mounting the power monitoring circuit on the power supply board, it may be mounted on a board that is backed up by a backup power supply (for example, the main board 31). In addition, a clear signal indicating that a clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 1560.

A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. Furthermore, since the production control command and the production control INT signal are output from the main board 31 via the I / O port unit which is a unidirectional circuit, the signal going from the relay board 77 to the inside of the main board 31 is restricted. . That is, the signal from the relay board 77 does not enter the inside of the main board 31 (the game control microcomputer 156 side).

  Further, the effect control CPU 120 (not shown) outputs a signal for driving the LED to the lamp driver board 35 via an output port (not shown). Further, the effect control CPU 120 outputs sound number data to the sound control board 70 via the output port.

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver outputs drive signals to each LED provided on the frame side such as the top frame LED 28a, the left frame LED 28b, and the right frame LED 28c, and each LED provided on the light guide plate unit 700 such as the light guide plate LED 60, the decorative body 301, and the like.

  In the voice control board 70, the sound number data is input to a voice synthesis IC (not shown) via an input driver (not shown). The voice synthesizing IC generates voice and sound effects corresponding to the sound number data and outputs them to an amplifier circuit (not shown). The amplifier circuit outputs to the speaker 27 an audio signal obtained by amplifying the output level of the voice synthesis IC to a level corresponding to the volume set by the volume. Control data corresponding to sound number data is stored in a sound data ROM (not shown). The control data corresponding to the sound number data is a collection of data showing the output form of the sound effect or sound in a time series in a predetermined period (for example, the changing period of the effect design).

The rear end surface of the outer plate 602b of the member 602 and the front end surface of the outer plate 621a of the rear cover 603 face each other, and the rear end surface of the inner plate 601b of the decorative member 601 and the front end surface of the inner plate 621b of the rear cover 603 contact each other. Touch.

  That is, as shown in FIGS. 13 to 15, the rear end surfaces of the side plates 600 a, 601 b, 602 b constituting the side peripheral wall of the front cover 606, and the front end surfaces of the side plates 621 a, 621 b constituting the side peripheral wall of the rear cover 603, Faces or abuts in a state where both are assembled. And the board insertion recessed part 650 is formed in a part of front end surface of the side peripheral wall in the rear cover 603 because the height dimension L1 of the outer side plate 621a in the rear cover 603 is shorter than the height dimension L2 of the inner side plate 621b. The outer peripheral edge 610 a of the decorative substrate 604 is inserted into the substrate insertion recess 650. That is, the edge of the decorative substrate 604 on the outer peripheral edge 610a side is sandwiched between the outer side plate 621a and the side plates 600a and 602b.

  In other words, the screw 622 as the fastening means includes an opening peripheral end surface of the front cover 606 (a rear end surface of the side plate 600a and an outer end surface of the outer plate 602b) and an opening peripheral end surface of the rear cover 603 (a front end surface of the outer plate 621a). The front cover 606 and the rear cover 603 are fastened so as to sandwich the outer peripheral edge 610a of the decorative substrate 604. The front cover 606 and the rear cover 603 constituting the stage frame ornament 11 constitute a substrate case of the present invention that covers the ornament substrate 604.

  The front cover 606 and the rear cover 603 are formed in a box shape with one surface opened by a base plate and a side plate connected to the periphery of the base plate, but a box-shaped cover member partially opened. As long as the shape is arbitrary, for example, a dome-shaped cover member may be used.

  As described above, the decorative substrate 604 has at least a part of its peripheral edge inserted between the peripheral wall of the front cover 606 and the peripheral wall of the rear cover 603, and the front surface 604 F is the front cover 606 and the rear surface 604 B is the rear cover 603. By covering, the stage frame decoration LEDs 61 and 62 can be arranged as close to the side plates of the front cover 606 and the rear cover 603 as possible.

  More specifically, when the substrate on which the LED is disposed is accommodated in a case that protects the LED, the substrate is formed slightly smaller than the accommodation case in advance in consideration of errors during molding and processing. There is a need. In addition, if a wiring pattern is formed at the edge of the substrate, it may be difficult to dispose the LED on the edge of the substrate because there is a risk of disconnection due to errors in molding or processing. As a result, when the LED substrate is accommodated in the accommodation case, the substrate becomes small and the LEDs cannot be arranged at the edge, so that the degree of freedom of LED arrangement is limited.

  Therefore, as in the present embodiment, a part of the edge of the decorative substrate 604 can be inserted into the substrate insertion recess 650 formed between the end surfaces of the side plates 621a and 600a of the front and rear covers 603 and 606, thereby providing wiring. Even if the LED is arranged by forming a pattern inside the edge portion, the LED can be arranged close to the side plate 621a, so that the degree of freedom of arrangement of the LED is effectively increased. Even if an error or the like occurs during molding or processing of the decorative substrate 604, the decorative substrate 604 can be easily manufactured because the error is allowed by protruding the outer peripheral edge 610a to the outside.

  In the present embodiment, the front cover 606 and the rear cover 603 are configured to be fastened by the screw 622 in the covered state, but are fastened in the covered state by means other than the screw member, such as a latch member or a locking claw. You may be made to do.

  Further, as shown in FIGS. 13A and 14A, a screw hole in which a screw 622 for fastening the rear cover 603 and the front cover 606 is attached to a predetermined portion of the outer peripheral edge 610a of the decorative substrate 604. Since notched recesses 609a to 609c for avoiding contact with the bosses 624a to 624c having 625 are formed, the conductive screw 622 and the wiring pattern are in contact with each other, and high voltage due to static electricity causes the stage frame decoration LED 61, It is possible to avoid destroying 62 and the IC chip 615.

  In particular, the edge of the cutout recess 609 b in the decorative substrate 604 is formed by the rear end edge of the cylindrical wall portion 626 ′ of the decorative member 602 constituting the front cover 606 and the front end surface of the cylindrical wall portion 626 of the rear cover 603. Since the conductive screw 622 and the wiring pattern are cut off by the cylindrical wall portion 626 by being sandwiched from the front and the back, the high voltage due to static electricity due to dust or dirt is generated and the stage frame decoration LEDs 61 and 62 and The destruction of the IC chip 615 can be avoided.

  In this embodiment, the notch recesses 609a to 609c in the decorative substrate 604 are for avoiding contact with the screws 622 and the bosses 624a to 624c having the screw holes 625 for fastening the rear cover 603 and the front cover 606. However, for example, the stage frame decoration 11 having the rear cover 603 and the front cover 606 may be for avoiding contact with the mounting screws for mounting the panel surface plate 250 or the like.

  As shown in FIG. 16, the stage frame decoration 11 configured in this way is fitted from the front side into an opening 201 formed in the board surface plate 200, and a proper position of the flange plate 600 is fixed to the board surface plate 200. It is attached by. On the back side of the light emitting decoration part 605, a movable part 800 of the effect device 500 provided on the decoration body 301 is provided so as to be able to move up and down between an ascending position and a descending position, and light is directed toward the back side. The stage frame decoration LED 62 provided so as to emit light emits light, so that the movable part 800 and the decorations in the vicinity thereof are illuminated.

  Since the rear cover 603 is formed with the light projection holes 629a to 629d, it is possible to directly irradiate the decoration target portion with the light from the stage frame decoration LED 62 without being attenuated by the rear cover 603. Thus, the decoration target part can be effectively decorated. Further, since the light projecting holes 629a to 629d are not visible from the player side, not only the appearance does not deteriorate, but the direct light from the LED is not directly irradiated to the player's eyes, which is safe.

  Further, the edge on the outer peripheral edge 610a side of the decorative substrate 604 is inserted between the side plate end faces of the front and rear covers 606, 603, so that the inner periphery of the opening 201 is not exposed to the inner peripheral side of the stage frame decoration 11. Since it faces the surface, not only the appearance appearance is not impaired, but also the contact between the game ball and the substrate can be surely avoided.

  Further, in this embodiment, the stage frame decoration substrate 604 whose front and rear surfaces are covered by the front cover 606 and the rear cover 603 is provided on the stage frame decoration 11, but such a substrate covering structure has a stage frame decoration. It can be applied to places other than 11.

  Further, the decoration substrate 604 is provided with stage frame decoration LEDs 61 and 62 and IC chips 615 as electronic components on the front surface 604F and the back surface 604B, but is mounted only on either the front surface 604F or the back surface 604B. Also good.

  In the embodiment, the screw 622 as the fastening means includes the opening peripheral end surface of the front cover 606 (the rear end surface of the side plate 600a and the outer end plate 602b) and the opening peripheral end surface of the rear cover 603 (the front end of the outer plate 621a). The front cover 606 and the rear cover 603 are fastened so that the outer peripheral edge 610a of the decorative substrate 604 is sandwiched between the front cover 606 and the rear cover 603. Even if the peripheral edge surface of the opening is in contact with the front and rear surfaces of the outer peripheral edge 610a of the decorative substrate 604 and is not sandwiched from the front and rear, it may be close to the front and rear surfaces of the outer peripheral edge 610a of the decorative substrate 604.
