Description

  The present invention relates to a gaming machine in which a game is played by firing a game ball in a game area formed on a game board surface.

  As this type of gaming machine, a game ball, which is a game medium, is launched into a game area by a launching device, and when a game ball is won in a prize area such as a prize opening provided in the game area, a predetermined number of game balls are prized. There are some (award balls) that are paid out to the player. Furthermore, as a display result of the variable display of the special symbol (identification information) started in the variable display unit based on the winning of the game ball at the start winning opening, a predetermined specific display mode (specific display result) is provided. There is a gaming machine that shifts to a big hit gaming state (specific gaming state) when it is derived and displayed. When a big hit occurs, for example, the big winning opening (one of the winning areas) is opened a predetermined number of times (for example, 16 times), and the game state shifts to a specific gaming state where it is easy to win. And in each open period, if there is a prize for a predetermined number (for example, 10) of the big prize opening, the big prize opening is closed. Hereinafter, the opening period of each special winning opening is referred to as a round.

  In addition, there is a type of winning hole that includes a variable winning ball device that performs an operation from a closed state where a game ball cannot be won to an open state where a game ball can be won when a predetermined condition is satisfied. As an example of such a variable winning ball device, a movable plate provided in a path through which a game ball can enter in the game area can be advanced to the game area side in the path to guide the game ball to the start area And a state in which the game ball is retracted from the game area side and the game ball is not guided to the start area, and so on (see, for example, Patent Document 1).

The variable display control unit including the device 9 and the effect control board 80 and the like are mainly configured and detachably attached to the game board 6.

  Returning to FIG. 1, in the vicinity of the center of the game area 7, there is provided an effect display device (decorative symbol display device) 9 including a plurality of variable display units each variably displaying an effect decorative symbol (effect symbol). ing. The effect display device 9 includes, for example, three variable display portions (symbol display areas) of “left”, “middle”, and “right”. The effect display device 9 variably displays the effect symbol as a decoration (effect) symbol during the variable display period of the special symbol by the first special symbol indicator 8a or the second special symbol indicator 8b. The effect display device 9 that performs variable display of effect symbols is controlled by an effect control microcomputer mounted on the effect control board 80.

  A first special symbol display (first variable display means) 8a for variably displaying a first special symbol as first identification information is provided at a lower right position on the game board 6. In this embodiment, the first special symbol display 8a is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. In other words, the first special symbol display 8a is configured to variably display numbers (or symbols) from 0 to 9. A second special symbol display (second variable display means) 8b for variably displaying the second special symbol as the second identification information is provided above the first special symbol display 8a. The second special symbol display 8b is realized by a simple and small display (for example, 7 segment LED) capable of variably displaying numbers 0 to 9. That is, the second special symbol display 8b is configured to variably display numbers (or symbols) from 0 to 9.

  In this embodiment, the type of the first special symbol and the type of the second special symbol are the same (for example, both 0 to 9), but the types may be different. The first special symbol display 8a and the second special symbol display 8b each variably display a number (or a two-digit symbol) from 0 to 99 using, for example, two 7-segment LEDs. It may be configured.

  Hereinafter, the first special symbol and the second special symbol may be collectively referred to as a special symbol, and the first special symbol indicator 8a and the second special symbol indicator 8b may be collectively referred to as a special symbol indicator.

  The variable display of the first special symbol is a variable display start condition (for example, after the game ball has won the first start winning opening 13a) after the first start condition, which is the variable display execution condition, is established (for example, When the number of reserved memories is not 0, the variable display of the first special symbol is not executed, and the variable display is started based on the fact that the big hit game is not executed) When time (fluctuation time) elapses, a display result (stop symbol) is derived and displayed. In addition, the variable display of the second special symbol is a variable display start condition (for example, that the game ball has won the second start winning opening 13b) after the second start condition, which is a variable display execution condition, is satisfied (for example, For example, when the number of reserved memories is not 0, the variable display of the second special symbol is not executed, and the big hit game is not executed) is started, When the variable display time (variation time) elapses, the display result (stop symbol) is derived and displayed. Note that winning means that a game ball has entered a predetermined area such as a winning opening. Deriving and displaying the display result is to finally stop and display a symbol (an example of identification information).

  The effect display device 9 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display 8a and during the variable display time of the second special symbol on the second special symbol display 8b. Display design (also referred to as a decorative design) as a design. The variable display of the first special symbol on the first special symbol display 8a and the variable display of the effect symbol on the effect display device 9 are synchronized. Further, the variable display of the second special symbol on the second special symbol display 8b and the variable display of the effect symbol on the effect display device 9 are synchronized. Synchronous means that the start time and end time of variable display are substantially the same (may be exactly the same) and the variable display period is substantially the same (may be exactly the same). Further, when the jackpot symbol is stopped and displayed on the first special symbol display 8a and when the jackpot symbol is stopped and displayed on the second special symbol display 8b, the effect display device 9 reminds the jackpot The combination of is stopped and displayed.

  Below the effect display device 9, a winning device having a first start winning port 13a is provided. The game ball won in the first start winning opening 13a is guided to the back of the game board 6, and is detected by the first start opening switch 14a (for example, proximity switch) and the first winning confirmation switch 14b (for example, photo sensor). The

  A variable winning ball device 15 having a second starting winning port 13b through which a game ball can be won is provided below the winning device having the first starting winning port (first starting port) 13a. The game ball that has won the second start winning opening (second start opening) 13b is guided to the back of the game board 6 and detected by the second start opening switch 15a and the winning confirmation switch 15b. The variable winning ball device 15 is opened by a solenoid 16. When the variable winning ball apparatus 15 is in the open state, the game ball can be won in the second start winning opening 13b (it is easy to start winning), which is advantageous for the player. In a state where the variable winning ball device 15 is in the open state, it is easier for the game ball to win the second starting winning port 13b than the first starting winning port 13a. In addition, in a state where the variable winning ball device 15 is in the closed state, the game ball does not win the second start winning opening 13b. In the state where the variable winning ball apparatus 15 is in the closed state, it may be configured that the winning is possible (that is, it is difficult for the gaming ball to win) although it is difficult to win a prize.

  In addition, it is determined whether or not an abnormal winning has occurred based on the detection results of the first starting port switch 14a and the first winning confirmation switch 14b and the detection results of the second starting port switch 15a and the second winning confirmation switch 15b. A security signal is externally output based on the detection of the occurrence of.

  Hereinafter, the first start winning opening 13a and the second start winning opening 13b may be collectively referred to as a start winning opening or a starting opening.

  When the variable winning ball device 15 is controlled to be in the open state, the game ball heading for the variable winning ball device 15 is very likely to win the second start winning port 13b. The first start winning opening 13a is provided directly below the effect display device 9, but the interval between the lower end of the effect display device 9 and the first start winning port 13a is further reduced, or the first start winning port is set. The winning rate of the second starting winning port 13b is such that the nails are densely arranged around 13a, or the nail arrangement around the first starting winning port 13a is difficult to guide the game ball to the first starting winning port 13a. You may make it make higher than the winning rate of the 1st start winning opening 13a.

  In the upper part of the second special symbol display 8b, the number of effective winning balls that have entered the first start winning opening 13a, that is, the first reserved memory number (the reserved memory is also referred to as the start memory or the start prize memory) is displayed. A first special symbol reserved memory display section and the first special symbol reserved memory display section are provided separately, and a second special special display for displaying the number of effective winning balls that have entered the second start winning slot 13b, that is, the second reserved memory number. For example, a special symbol storage memory display unit 18 including a 7-segment LED provided with a symbol storage memory display unit is provided. The first special symbol reserved memory display unit displays up to four first reserved memory numbers in the order of winning, and increases the number of indicators that are turned on by 1 each time there is an effective start winning. Then, each time the variable display on the first special symbol display 8a is started, the number of indicators to be turned on is reduced by one. The second special symbol reserved memory display unit displays up to four second reserved memory numbers in the order of winning, and increases the number of indicators that are turned on by 1 each time there is an effective start winning. Then, each time the variable display on the second special symbol display 8b is started, the number of indicators to be turned on is reduced by one. In this example, the upper limit number (up to 4) is provided for the start memory number by winning at the first start winning port 13a and the start memory number by winning at the second start winning port 13b. May be four or more.

  Further, the display screen of the effect display device 9 is provided with a first reserved memory display unit 9a for displaying the first reserved memory number and a second reserved memory display unit 9b for displaying the second reserved memory number. . In addition, you may make it provide the area | region (sum total pending | holding memory display part) which displays the total number (sum total pending memory count) which is the sum total of the 1st pending memory count and the 2nd pending memory count. As described above, if the summation pending storage display section for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that are not satisfied with the variable display start condition.

  In this embodiment, as shown in FIG. 1, a variable winning ball device 15 that opens and closes only with respect to the second start winning opening 13b is provided, but the first start winning opening 13a and the second start winning opening 13b are provided.

In the specific gaming state (big hit gaming state) that occurs when the specific display result (big hit symbol) is derived and displayed on the screen, the big winning opening door 20b is controlled to be opened by the solenoid 21 so that the big winning that becomes the winning area The mouth 20a (see FIG. 11) is opened.

  Two switches (a count switch 23 and a third winning confirmation switch 23a) capable of detecting a game ball won in the large winning opening 20a are provided in the large winning opening 20a. In this embodiment, a count switch 23 and a third winning confirmation switch 23a are arranged in the special winning opening 20a (in this example, the counting switch 23 is arranged on the upper side and the third winning confirmation switch 23a is on the lower side. Placed on the side). Therefore, in this embodiment, the game ball won in the special winning opening 20a is led to the back of the game board 6, first detected by the count switch 23, and then detected by the third winning confirmation switch 23a.

  Based on the detection of the game balls by the count switch 23, a predetermined number (for example, 15) of game balls are paid out as prize balls. In this way, when the game ball passes (enters) the large winning opening 20a that has been opened in the special variable winning ball apparatus 20, another winning opening such as the first starting winning opening 13a and the second starting winning opening 13b is opened. More prize balls are paid out than when game balls pass (enter). Therefore, if the special winning opening 20a is opened in the special variable winning ball apparatus 20, a first state advantageous to the player is obtained. On the other hand, if the special prize winning device 20 is closed in the special variable prize winning device 20, the game ball cannot pass through (enter) the special prize winning opening 20a to obtain a prize ball, which is disadvantageous for the player. The second state is entered.

In this embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. When the lamp on the lower side of the normal symbol display 10 is turned on and it is a win, the variable winning ball device 15 is opened for a predetermined number of times. That is, the state of the variable winning ball device 15 is a state that is advantageous from a disadvantageous state for the player when the lower lamp is lit (a state in which a game ball can win the second start winning opening 13b). ). An upper part of the special symbol storage memory display 18 is provided with a normal symbol storage memory display 41 having four display portions (for example, four segments among seven segment LEDs) for displaying the number of winning balls that have passed through the gate 32. It has been. Each time there is a game ball passing through the gate 32, that is, every time a game ball is detected by the gate switch 32a, the normal symbol storage memory display 41 increases the number of display units to be turned on by one. Then, each time the variable display of the normal symbol display 10 is started, the number of display units that are lit is reduced by one.

  In addition, the normal symbol holding memory display 41 composed of 7-segment LEDs has four display units (segments) for displaying the number of winning balls that have passed through the gate 32 and, for example, the number of times the special variable winning ball device 20 is opened at the time of a big hit. There are two display units (segments) that indicate (the number of big hits) and two display units (segments) that indicate the gaming state, but these display units are separate from the normal symbol hold storage display unit. You may comprise. Further, the normal symbol display 10 may be configured by a segment LED or the like that can variably display a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  A game ball launched from a hitting ball launching device, which will be described later, by the player's operation enters the game area 7 through a shot ball guide passage (not shown), 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 at the time of stop (stop symbol) is a big hit symbol (specific display result), it will be “big hit”, and the special symbol at the time of stop (stop symbol) 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 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 ball payout device 97 is a device for paying out a game ball guided by a passage for guiding the game ball and a sprocket driven by a stepping motor or the like to an upper plate or a lower plate. A payout number counting switch for counting prize balls and rental balls is also configured as part of the unit. In this embodiment, the payout detection means is realized by a payout number count switch, and has a function of detecting that a winning ball or a lending ball is actually paid out from the ball payout device 97. In this case, the payout number count switch outputs a detection signal every time one payout of prize balls or rental balls is detected.

  On the back surface of the pachinko gaming machine 1, a terminal board 91 having terminals for outputting various information to the outside of the pachinko gaming machine 1 is installed.

Above the ball payout device 97, a ball break switch 43 is provided as a game medium break detection means. When the ball break switch 43 detects a ball break, the payout operation of the ball payout device 97 stops. When the ball break switch 43 detects a shortage of game balls, the game balls are replenished to the pachinko gaming machine 1 from the replenishment mechanism provided on the gaming machine installation island.

  When a large number of game balls as prizes based on winning a prize or a game ball based on a ball lending request are paid out and the hitting ball supply tray 3 is full, the game balls are guided to the surplus ball receiving tray 4 through the surplus ball guiding path. Further, when the game ball is paid out, a sensing lever (not shown) presses a full tank switch (not shown) as the storage state detection means, and the full tank switch as the storage state detection means is turned on.

  FIG. 3 is a block diagram showing an example of the circuit configuration of the main board (game control board) 31. FIG. 3 also shows a payout control board 37, an effect control board 80, and the like. A game control microcomputer (corresponding to game control means) 156 for controlling the pachinko gaming machine 1 according to a program is mounted on the main board 31. The game control microcomputer 156 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means used as a work memory, a CPU 56 for performing control operations in accordance with the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and the RAM 55 are built in the game control microcomputer 156. That is, the game control microcomputer 156 is a one-chip microcomputer. The one-chip microcomputer only needs to include at least the RAM 55, and the ROM 54 may be external or internal. The I / O port unit 57 may be externally attached. The game control microcomputer 156 further includes a random number circuit 60 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 156, the CPU 56 executes control in accordance with a program stored in the ROM 54. Therefore, the game control microcomputer 156 (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 156 includes a random number circuit 60. The random number circuit 60 is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 60 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 60 is a hardware circuit that is used to generate a random number for determination to determine whether or not to win a jackpot based on a display result of variable symbol special display. The random number circuit 60 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 60 is configured to select a numeric data update range selection setting function (initial value selection setting function and upper limit selection selection 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 156 has a function of setting an initial value of numerical data updated by the random number circuit 60. For example, a predetermined calculation is performed using an ID number of the game control microcomputer 156 stored in a predetermined storage area such as the ROM 54 (an ID number assigned with a different value for each product of the game control microcomputer 156). The numerical data obtained by the setting is set as the initial value of the numerical data updated by the random number circuit 60. By performing such processing, the randomness of the random number generated by the random number circuit 60 can be further improved.

  The game control microcomputer 156 reads the numerical data as random R from the random number circuit 60 when the 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.

  Further, the game control microcomputer 156 is used for inputting / outputting (transmitting / receiving) 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 61 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 156 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 156. A reset circuit for generating a reset signal supplied to the game control microcomputer 156 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 156 and the like are in an operable state, and when the reset signal becomes low level, the game control microcomputer 156 and the like become inactive. Therefore, an allowable signal that allows the operation of the game control microcomputer 156 or the like is output during a period in which the reset signal is at a high level, and a game control microcomputer in which the reset signal is at a low level. An operation stop signal for stopping the operation of 156 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).

  Further, 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 156. 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). Further, a clear signal indicating that the clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 156.

  Further, the gate switch 32a, the first start opening switch 14a, the first winning confirmation switch 14b, the second starting opening switch 15a, the second winning confirmation switch 15b, the count switch 23, the third winning confirmation switch 23a, and each winning opening switch 30a. , 30b, and an input driver circuit 58 for supplying a detection signal to the basic circuit is also mounted on the main board 31, and includes a solenoid 16 for opening / closing the variable winning ball apparatus 15, a solenoid 21 for opening / closing the special variable winning ball apparatus 20, and a regulating plate 730. A swinging solenoid 22 and an output circuit 59 driven in accordance with a command from the basic circuit are also mounted on the main board 31, and a system reset circuit (not shown) for resetting the game control microcomputer 156 when the power is turned on, Information output signals such as jackpot information indicating the occurrence of jackpot gaming state, Through a null substrate 91, the information output circuit 64 for outputting to an external device such as a hall computer also mounted on the main substrate 31.

  In this embodiment, the effect control means (configured by the effect control microcomputer) mounted on the effect control board 80 instructs the effect contents from the game control microcomputer 156 via the relay board 77. The control command is received, and display control with the effect display device 9 that variably displays the effect symbol is performed.

  The effect control board 80 is equipped with an effect control microcomputer (not shown) including an effect control CPU and a RAM. The RAM may be externally attached. In the effect control board 80, an effect control CPU (not shown) operates according to a program stored in a built-in or external ROM (not shown), and receives from the main board 31 inputted via the relay board 77. An effect control command is received via the input driver and the input port in response to the embedded signal (effect control INT signal). Further, the effect control CPU (not shown) causes the VDP (video display processor) to perform display control of the effect display device 9 based on the effect control command.

  An effect control CPU (not shown) reads necessary data from a character ROM (not shown) in accordance with the received effect control command. The character ROM is for storing character image data displayed on the effect display device 9, specifically, a person, characters, figures, symbols, etc. (including effect symbols) in advance. An effect control CPU (not shown) outputs the data read from the character ROM to the VDP. The VDP performs display control based on data input from the CPU for effect control.

  The effect control command and the effect control INT signal are first input to the input driver on the effect control board 80. The input driver allows the signal input from the relay board 77 to pass only in the direction toward the inside of the effect control board 80 (does not pass the signal in the direction from the inside of the effect control board 80 to the relay board 77). It is also a unidirectional circuit as a means.

  As a signal direction regulating means, the signal inputted from the main board 31 is allowed to pass through the relay board 77 only in the direction toward the effect control board 80 (the signal is not passed in the direction from the effect control board 80 to the relay board 77). 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 (not shown) outputs a signal for driving the LED to the lamp driver board 35 via an output port (not shown). The effect control CPU outputs sound number data to the sound control board 70 via the output port. The effect control CPU outputs a drive signal to the drive motor 516 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 supplies a drive signal 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. Further, a drive signal is supplied to the decoration LED 25a provided on the game board side. When a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 35.

  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).

  Next, the operation of the gaming machine will be described. FIG. 4 is a flowchart showing main processing executed by the game control microcomputer 156 on the main board 31. When power is supplied to the gaming machine and power supply is started, the input level of the reset terminal to which the reset signal is input becomes high level, and the gaming control microcomputer 156 (specifically, the CPU 56) After executing a security check process, which is a process for confirming whether the contents of the program are valid, the main process after step S1 is started. In the main process, the CPU 56 first performs necessary initial settings.

  In the initial setting process, the CPU 56 first sets the interrupt prohibition (step S1). Next, the interrupt mode is set to interrupt mode 2 (step S2), and a stack pointer designation address is set to the stack pointer (step S3). After initialization of the built-in device (CTC (counter / timer) and PIO (parallel input / output port), which are built-in devices (built-in peripheral circuits)) is performed (step S4), the RAM is accessible (Step S5). In interrupt mode 2, the address synthesized from the value (1 byte) of the specific register (I register) built in the CPU 56 and the interrupt vector (1 byte: least significant bit 0) output from the built-in device is This mode indicates an interrupt address.

  Next, the CPU 56 checks the state of the output signal (clear signal) of a clear switch (for example, mounted on the power supply board) input via the input port (step S6). When the ON is detected in the confirmation, the CPU 56 executes normal initialization processing (steps S10 to S15).

  If the clear switch is not on, check whether data protection processing of the backup RAM area (for example, power supply stop processing such as addition of parity data) was performed when power supply to the gaming machine was stopped (Step S7). When it is confirmed that such protection processing is not performed, the CPU 56 executes initialization processing. Whether there is backup data in the backup RAM area is confirmed, for example, by the state of the backup flag set in the backup RAM area in the power supply stop process.

  When it is confirmed that the power supply stop process has been performed, the CPU 56 performs data check of the backup RAM area (step S8). In this embodiment, a parity check is performed as a data check. Therefore, in step S8, the calculated checksum is compared with the checksum calculated and stored by the same process in the power supply stop process. When the power supply is stopped after an unexpected power failure or the like, the data in the backup RAM area should be saved, so the check result (comparison result) is normal (matched). That the check result is not normal means that the data in the backup RAM area is different from the data when the power supply is stopped. In such a case, since the internal state cannot be returned to the state when the power supply is stopped, an initialization process that is executed when the power is turned on is not performed when the power supply is stopped.

  If the check result is normal, the CPU 56 recovers the game state restoration process (steps S41 to S43) for returning the internal state of the game control means and the control state of the electrical component control means such as the effect control means to the state when the power supply is stopped. Process). Specifically, the start address of the backup setting table stored in the ROM 54 is set as a pointer (step S41), and the contents of the backup setting table are sequentially set in the work area (area in the RAM 55) (step S42). ). The work area is backed up by a backup power source. In the backup setting table, initialization data for an area that may be initialized in the work area is set. As a result of the processing in steps S41 and S42, the saved contents of the work area that should not be initialized remain as they are. The part that should not be initialized is, for example, data indicating the gaming state before the power supply is stopped (special symbol process flag, probability variation flag, time reduction flag, etc.), and the area where the output state of the output port is saved (output port buffer ), A portion in which data indicating the number of unpaid prize balls is set.

  Further, the CPU 56 transmits a power failure recovery designation command as an initialization command at the time of power supply recovery (step S43). Then, the process proceeds to step S14. In this embodiment, the CPU 56 also transmits, to the effect control board 80, a total pending storage number designation command in which the value of the total pending storage number counter stored in the backup RAM is set in the process of step S43.

  In this embodiment, it is confirmed whether the data in the backup RAM area is stored using both the backup flag and the check data, but only one of them may be used. That is, either the backup flag or the check data may be used as an opportunity for executing the game state restoration process.

  In the initialization process, the CPU 56 first performs a RAM clear process (step S10). The RAM clear process initializes predetermined data (for example, count value data of a counter for generating a random number for normal symbol determination) to 0, but an arbitrary value or a predetermined value It may be initialized to. In addition, the entire area of the RAM 55 may not be initialized, and predetermined data (for example, count value data of a counter for generating a random number for normal symbol determination) may be left as it is. Further, the start address of the initialization setting table stored in the ROM 54 is set as a pointer (step S11), and the contents of the initialization setting table are sequentially set in the work area (step S12).

  By the processing in steps S11 and S12, for example, a normal symbol per-determining random number counter, a special symbol buffer, a total prize ball number storage buffer, a special symbol process flag, and other flags for selectively performing processing according to the control state are initialized. A value is set.

  In addition, the CPU 56 initializes a sub board (a board on which a microcomputer other than the main board 31 is mounted). An initialization designation command (a command indicating that the game control microcomputer 156 has executed initialization processing). Is also transmitted to the sub-board (step S13). For example, when receiving the initialization designation command, the effect control microcomputer performs display on the effect display device 9 for notifying that the control of the gaming machine has been initialized, that is, initialization notification.

  Further, the CPU 56 executes a random number circuit setting process for initial setting of the random number circuit 503 (step S14). For example, the CPU 56 performs setting according to the random number circuit setting program to cause the random number circuit 503 to update the value of the random R.

  In step S15, the CPU 56 sets a CTC register built in the game control microcomputer 156 so that a timer interrupt is periodically generated every predetermined time (for example, 2 ms). That is, a value corresponding to, for example, 2 ms is set in a predetermined register (time constant register) as an initial value. In this embodiment, it is assumed that a timer interrupt is periodically taken every 2 ms.

  When the execution of the initialization process (steps S10 to S15) is completed, the CPU 56 repeatedly executes the display random number update process (step S17) and the initial value random number update process (step S18) in the main process. When the display random number update process and the initial value random number update process are executed, the interrupt disabled state is set (step S16). Set (step S19). In this embodiment, the display random number is a random number for determining the stop symbol of the special symbol when it is not a big hit, or a random number for determining whether to reach when it is not a big hit, The random number update process is a process for updating the count value of a counter for generating a display random number. The initial value random number update process is a process for updating the count value of the counter for generating the initial value random number. In this embodiment, the initial value random number determines the initial value of the count value of a counter for generating a random number for determining whether or not to win a normal symbol (ordinary random number generation counter for normal symbol determination). It is a random number to do. A game control process for controlling the progress of the game, which will be described later (the game control microcomputer 156 controls itself a game device such as an effect display device, a variable winning ball device, a ball payout device, etc. provided in the gaming machine. In the process of transmitting a command signal to be controlled by another microcomputer, or a game machine control process), the count value of the random number for determination per normal symbol is one round (the random number for determination per normal symbol is taken). When the value is incremented by the number of values between the minimum value and the maximum value of the possible values), an initial value is set in the counter.

  In this embodiment, the reach effect is executed using an effect symbol (decorative symbol) variably displayed on the effect display device 9. Further, when the display result of the special symbol is a jackpot symbol, the reach effect is always executed. When the display result of the special symbol is not a jackpot symbol, the game control microcomputer 156 determines whether or not to execute the reach effect by lottery using a random number. However, it is the production control microcomputer that actually executes the reach production control.

  When the timer interrupt occurs, the CPU 56 executes the timer interrupt process of steps S20 to S34 shown in FIG. In the timer interrupt process, first, a power-off detection process for detecting whether or not a power-off signal is output (whether or not an on-state is turned on) is executed (step S20). The power-off signal is output, for example, when a power supply monitoring circuit mounted on the power supply board detects a decrease in the voltage of the power supplied to the gaming machine. In the power-off detection process, when detecting that the power-off signal has been output, the CPU 56 executes a power supply stop process for saving necessary data in the backup RAM area. Next, detection signals of the gate switch 32a, the first start port switch 13a, the second start port switch 14a, and the count switches 23 and 24 are input via the input driver circuit 58, and the state determination is performed (switch processing: Step S21).

  Next, the CPU 56 has a first special symbol display 8a, a second special symbol display 8b, a normal symbol display 10, a first special symbol hold storage display 18a, a second special symbol hold storage display 18b, a normal symbol. A display control process for controlling the display of the on-hold storage display 41 is executed (step S22). About the 1st special symbol display 8a, the 2nd special symbol display 8b, and the normal symbol display 10, a drive signal is output with respect to each display according to the content of the output buffer set by step S32, S33. Execute control.

  Also, a process of updating the count value of each counter for generating each random number for determination such as a random number for determination per ordinary symbol used for game control is performed (determination random number update process: step S23). The CPU 56 further performs a process of updating the count value of the counter for generating the initial value random number and the display random number (initial value random number update process, display random number update process: steps S24 and S25).

  Further, the CPU 56 performs special symbol process processing (step S26). In the special symbol process, corresponding processing is executed in accordance with a special symbol process flag for controlling the first special symbol indicator 8a, the second special symbol indicator 8b, and the big prize opening 20a in a predetermined order. The CPU 56 updates the value of the special symbol process flag according to the gaming state.

  Next, normal symbol process processing is performed (step S27). In the normal symbol process, the CPU 56 executes a corresponding process according to the normal symbol process flag for controlling the display state of the normal symbol display 10 in a predetermined order. The CPU 56 updates the value of the normal symbol process flag according to the gaming state.

  Further, the CPU 56 performs a process of sending an effect control command to the effect control microcomputer (effect control command control process: step S28).

  Further, the CPU 56 performs information output processing for outputting data such as jackpot information, start information, probability variation information supplied to the hall management computer, for example (step S29).

  Further, the CPU 56 executes a prize ball process for setting the number of prize balls based on detection signals from the first start port switch 13a, the second start port switch 14a and the count switch 23 (step S30). Specifically, the payout control micro mounted on the payout control board 37 in response to the winning detection based on any one of the first start port switch 13a, the second start port switch 14a and the count switch 23 being turned on. A payout control command (prize ball number signal) indicating the number of prize balls is output to the computer. The payout control microcomputer drives the ball payout device 97 in accordance with a payout control command indicating the number of winning balls.

  In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. However, the CPU 56 relates to solenoid on / off in the RAM area corresponding to the output state of the output port. Is output to the output port (step S31: output process).

  Further, the CPU 56 performs a special symbol display control process for setting special symbol display control data for effect display of special symbols in the output buffer for setting the special symbol display control data according to the value of the special symbol process flag ( Step S32). For example, if the variation speed is 1 frame / 0.2 seconds until the end flag is set when the start flag set in the special symbol process is set, the CPU 56, for example, every 0.2 seconds passes. Then, the value of the display control data set in the output buffer is incremented by one. Further, the CPU 56 outputs a drive signal in step S22 in accordance with the display control data set in the output buffer, whereby the first special symbol display unit 8a and the second special symbol display unit 8b Variable display of the second special symbol is executed.

  Further, the CPU 56 performs a normal symbol display control process for setting normal symbol display control data for effect display of the normal symbol in an output buffer for setting the normal symbol display control data according to the value of the normal symbol process flag ( Step S33). For example, when the start flag related to the variation of the normal symbol is set, the CPU 56 switches the display state (“◯” and “×”) for the variation rate of the normal symbol every 0.2 seconds until the end flag is set. With such a speed, the value of the display control data set in the output buffer (for example, 1 indicating “◯” and 0 indicating “x”) is switched every 0.2 seconds. Further, the CPU 56 outputs a normal signal on the normal symbol display 10 by outputting a drive signal in step S22 according to the display control data set in the output buffer.

  Thereafter, the interrupt permission state is set (step S34), and the process is terminated.

  With the above control, in this embodiment, the game control process is started every 2 ms. The game control process corresponds to the processes in steps S21 to S33 (excluding step S29) in the timer interrupt process. In this embodiment, the game control process is executed by the timer interrupt process. However, in the timer interrupt process, for example, only a flag indicating that an interrupt has occurred is set, and the game control process is performed in the main process. It may be executed.

  6 and 7 are flowcharts showing an example of a special symbol process (step S26) program executed by the game control microcomputer 156 (specifically, the CPU 56) mounted on the main board 31. FIG. As described above, in the special symbol process process, the process for controlling the first special symbol display 8a or the second special symbol display 8b and the special winning opening 20a is executed. In the special symbol process, the CPU 56 turns on the first start winning opening 13 when the first start opening switch 13a for detecting that the game ball has won the first start winning opening 13 is turned on. If a winning has occurred, a first start port switch passage process is executed (steps S311 and S312). If the second start port switch 14a for detecting that the game ball has won the second start winning port 14 is turned on, that is, the start winning to the second start winning port 14 has occurred. Then, the second start port switch passage process is executed (steps S313, S314). Then, any one of steps S300 to S310 is performed. If the first start port switch 13a or the second start port switch 14a is not turned on, any one of steps S300 to S310 is performed according to the internal state.

  The processes in steps S300 to S312 are as follows.

  Special symbol normal processing (step S300): Executed when the value of the special symbol process flag is zero. When the game control microcomputer 156 is in a state where variable display of a special symbol can be started, the game control microcomputer 156 checks the number of numerical data stored in the reserved storage number buffer (total number of reserved storage). The stored number of numerical data stored in the pending storage number buffer can be confirmed by the count value of the total pending storage number counter. If the count value of the total pending storage number counter is not 0, it is determined whether or not the display result of the variable display of the first special symbol or the second special symbol is a big hit. In case of big hit, set big hit flag. Then, the internal state (special symbol process flag) is updated to a value (1 in this example) according to step S301. The jackpot flag is reset when the jackpot game ends.

  Fluctuation pattern setting process (step S301): This process is executed when the value of the special symbol process flag is 1. Also, the variation pattern is determined, and the variation time in the variation pattern (variable display time: the time from the start of variable display until the display result is derived and displayed (stop display)) is defined as the variation display variation time of the special symbol. Decide to do. Also, a variable time timer for measuring the special symbol variable time is started. Then, the internal state (special symbol process flag) is updated to a value (2 in this example) corresponding to step S302.

  Display result designation command transmission process (step S302): This process is executed when the value of the special symbol process flag is 2. Control is performed to transmit a display result designation command to the effect control microcomputer. Then, the internal state (special symbol process flag) is updated to a value (3 in this example) corresponding to step S303.

  Special symbol changing process (step S303): This process is executed when the value of the special symbol process flag is 3. When the variation time of the variation pattern selected in the variation pattern setting process elapses (the variation time timer set in step S301 times out, that is, the variation time timer value becomes 0), the internal state (special symbol process flag) is stepped. Update to a value corresponding to S304 (4 in this example).

  Special symbol stop process (step S304): executed when the value of the special symbol process flag is 4. The variable display on the first special symbol display 8a or the second special symbol display 8b is stopped, and the stop symbol is derived and displayed. Also, control is performed to transmit a symbol confirmation designation command to the effect control microcomputer. If the big hit flag is set, the internal state (special symbol process flag) is updated to a value (5 in this example) corresponding to step S305. If the small hit flag is set, the internal state (special symbol process flag) is updated to a value (8 in this example) corresponding to step S308. If neither the big hit flag nor the small hit flag is set, the internal state (special symbol process flag) is updated to a value corresponding to step S300 (in this example, 0). The effect control microcomputer controls the effect display device 9 to stop the effect symbol when receiving the symbol confirmation designation command transmitted by the game control microcomputer 156.

  Preliminary winning opening opening process (step S305): This is executed when the value of the special symbol process flag is 5. In the pre-opening process for the big prize opening, control for opening the big prize opening 20a is performed. Specifically, a counter (for example, a counter that counts the number of game balls that have entered the special winning opening 20a) is initialized, and the solenoids 21 and 22 are driven to open the special winning opening 20a. Also, the execution time of the special prize opening opening process is set by the timer, and the internal state (special symbol process flag) is updated to a value corresponding to step S306 (6 in this example). The pre-opening process for the big winning opening is executed for each round, but when the first round is started, the pre-opening process for the big winning opening is also a process for starting the big hit game.

  Large winning opening opening process (step S306): This process is executed when the value of the special symbol process flag is 6. A control for transmitting an effect control command for round display during the big hit gaming state to the microcomputer for effect control, a process for confirming the closing condition of the special winning opening 20a, and the like are performed. When the closing condition for the special winning opening 20a is satisfied and the winning ball detection waiting time has elapsed, the internal state (special symbol process flag) is updated to a value corresponding to step S307 (7 in this example). .

  Post-winner opening process (step S307): This process is executed when the value of the special symbol process flag is 7. A control for transmitting an effect control command for round display during the big hit gaming state to the microcomputer for effect control, a process for confirming the closing condition of the special winning opening 20a, and the like are performed. If the closing condition for the special winning opening 20a is satisfied and there are still remaining rounds, the internal state (special symbol process flag) is updated to a value corresponding to step S305 (5 in this example). When all the rounds are finished, the internal state (special symbol process flag) is updated to a value (8 in this example) corresponding to step S308.

  Big hit end process (step S308): executed when the value of the special symbol process flag is 8. Control is performed to cause the microcomputer for effect control to perform display control for notifying the player that the big hit gaming state has ended. In addition, a process for setting a flag indicating a gaming state (for example, a probability change flag or a time reduction flag) is performed. Then, the internal state (special symbol process flag) is updated to a value (0 in this example) corresponding to step S300.

  Small hit release pre-processing (step S309): executed when the value of the special symbol process flag is 9. In the pre-opening process for small hits, control is performed to open the special winning opening 20a. Specifically, a counter (for example, a counter that counts the number of game balls that have entered the special winning opening 20a) is initialized, and the solenoids 21 and 22 are driven to open the special winning opening 20a. In addition, the execution time of the special prize opening opening process is set by the timer, and the internal state (special symbol process flag) is updated to a value corresponding to step S310 (10 in this example). It should be noted that although the pre-opening process for small hits is executed for each round, the pre-opening process for small hits is also a process for starting a small hit game when starting the first round.

  Small hit release process (step S310): This process is executed when the value of the special symbol process flag is 10. Processing for confirming the closing condition of the special winning opening 20a is performed. When the closing condition of the special winning opening 20a is satisfied and the winning ball detection waiting time has elapsed, the internal state (special symbol process flag) is updated to a value corresponding to step S311 (11 in this example). .

  After small hit release processing (step S311): executed when the value of the special symbol process flag is 11. Processing for confirming the closing condition of the special winning opening 20a is performed. If the closing condition for the special winning opening 20a is satisfied and there are still remaining rounds, the internal state (special symbol process flag) is updated to a value corresponding to step S309 (9 in this example). When all the rounds are finished, the internal state (special symbol process flag) is updated to a value (12 in this example) corresponding to step S312.

  Small hit end processing (step S312): executed when the value of the special symbol process flag is 12. Control is performed to cause the microcomputer for effect control to perform display control for notifying the player that the small hit gaming state has ended. Then, the internal state (special symbol process flag) is updated to a value (0 in this example) corresponding to step S300.

  FIG. 8 is a flowchart showing an example of the process executed in step S305 of FIG. In the pre-opening process for the big winning opening shown in FIG. 8, the CPU 56 first determines whether or not the big hit state start flag is on (step S391). At this time, if the big hit state start flag is ON (step S391; Yes), it is determined whether or not the big hit state start waiting time has elapsed (step S392). And if the big hit state start waiting time has not passed (step S392; No), it waits until the big hit state start waiting time passes by ending the big winning opening opening pre-processing. On the side of the effect control board 80, for example, an effect operation for notifying that the jackpot gaming state is started may be executed in a period until the jackpot state start waiting time elapses.

  When the big hit state start waiting time has elapsed in step S392 (step S392; Yes), the big hit state start flag is cleared and turned off (step S393). In addition, a setting for transmitting a big hit start command to the effect control board 80 is performed (step S394). Then, after setting the round start waiting time (step S395), the pre-opening process for the big prize opening is ended.

  When the big hit state pre-start flag is off in step S391 (step S391; No), it is determined whether or not the round start waiting has elapsed (step S396). At this time, if the round start waiting time has not elapsed (step S396; No), the process waits until the round start waiting time elapses by ending the pre-opening of the special winning opening.

  When the round start waiting time elapses in step S396 (step S396; Yes), the winning number counter is cleared and the winning number count value, which is the stored value, is initialized to “0” (step S397). In addition, a maximum winning opening maximum opening time (for example, 29000 ms) is set (step S398). At this time, for example, the solenoids 21 and 22 are driven and the special winning opening 20a is set to be opened by the special winning opening door 20b (step S399). Furthermore, a setting for transmitting a round start command to the effect control board 80 is performed (step S400). Then, after updating the value of the special figure process flag to “6” which is a value corresponding to the process for opening the big prize opening (step S401), the process for opening the big prize opening is ended.

  FIG. 9 is a flowchart showing an example of the process executed in step S306 of FIG. In the special winning opening opening process shown in FIG. 9, the CPU 56 first determines whether or not a winning ball detection waiting time is set (step S410), and when the winning ball detection waiting time is not set. (Step S410; No), it is determined whether or not the maximum winning opening maximum opening time has elapsed (Step S411). At this time, if the maximum winning opening maximum opening time has not elapsed (step S411; No), it is determined whether or not the count switch 23 is on (step S412), and if the count switch 23 is on (step S412). (S412; Yes), after updating the winning number count value to be incremented by 1 (step S413), a winning ball number command is transmitted to the payout control board 37 (step S414), and the process proceeds to step S415. If the count switch 23 is not on (step S412; No), the process proceeds to step S415.

  In step S415, it is determined whether or not the winning number count value has reached a predetermined maximum winning determination value (for example, “9”) (step S415). End the mouth open process.

  When the maximum opening time of the big winning opening has passed in step S411 (step S411; Yes), or when the round end condition is satisfied because the winning number count value has reached a predetermined maximum winning determination value in step S415 For example, the driving of the solenoids 21 and 22 is stopped and the special winning opening 20a is set to be closed by the special winning opening door 20b (step S416). Subsequently, after setting for transmitting a round end command to the effect control board 80 (step S417), a winning ball detection waiting time is set (step S418), and the process for opening the big prize opening is ended. To do.

  Here, the award ball detection waiting time is the time it takes for a game ball won immediately before closing the grand prize opening door 20b to pass the count switch 23, and the winning ball from the big prize opening 20a to the count switch 23 is taken. It is set according to the length of the guide passage 707 (see FIG. 16). That is, the game ball detected by the count switch 23 after closing the grand prize opening door 20b based on the establishment of the end condition of the above round is detected as the game ball that has won over the round, and the next It is not detected as a game ball won in a round.

  If the prize ball detection waiting time is set in step S410 (step S410; Yes), it is determined whether or not the prize ball detection waiting time has elapsed (step S420), and the prize ball detection waiting time has elapsed. If not (step S420; No), it is determined whether or not the detection signal from the count switch 23 is on (step S422). If the detection signal from the count switch 23 is on (step S422) (Step S422; Yes), a prize ball number command is transmitted to the payout control board 37 (Step S423), and the special winning opening opening process is terminated.

  Further, when the winning ball detection waiting time has elapsed in step S420 (step S420; Yes), the value of the special figure process flag is updated to “7” which is a value corresponding to the post-opening process for the big prize opening. (Step S421), the process for opening the special winning opening is ended.

  FIG. 10 is a flowchart showing an example of processing executed in step S307 of FIG. 7 as processing after the special winning opening is opened. In the post-opening process for the special winning opening shown in FIG. 10, the CPU 56 first updates the special winning opening open count value so that 1 is subtracted (step S431). At this time, it is determined whether or not the updated big opening opening count value is “0” (step S432). If the special winning opening opening count value is other than “0” (step S432; No), the round start waiting time is set (step S433), and the value of the special figure process flag is set to the special winning opening opening pre-processing. After the corresponding value is updated to “5” (step S434), the post-opening process for the big prize opening is terminated. Thus, until it is determined by the process of step S432 that the updated big opening opening count value is “0”, the process of steps S305 to S307 shown in FIG. Thus, it is possible to execute a plurality of round games in which the special variable winning ball apparatus 20 is opened.

  When the big prize opening release count value is “0” in step S432 (step S432; Yes), the time before the big hit end is set (step S435). At this time, the big hit flag is cleared and turned off (step S436). Then, after updating the value of the special figure process flag to “8” which is a value corresponding to the big hit end process (step S437), the post-opening process for the big prize opening is ended.

  Next, the special variable winning ball apparatus 20 will be described with reference to FIGS. FIG. 11A is a perspective view showing a closed state of the special variable winning ball apparatus, and FIG. 11B is a perspective view showing an open state of the special variable winning ball apparatus. FIG. 12 is an exploded perspective view showing the internal structure of the special variable winning ball apparatus. FIGS. 13A and 13B are exploded perspective views showing the drive mechanism of the prize winning door. 14A and 14B show the drive mechanism of the closed prize-winning door, in which FIG. 14A is a view taken along the arrow A in FIG. 12, and FIG. FIG. 15 is a diagram illustrating a drive mechanism of the open door for a special winning opening. FIG. 16 is a cross-sectional view showing the special variable winning ball apparatus in the closed state. FIG. 17 is a cross-sectional view showing the special variable winning ball apparatus in an open state. FIG. 18 is a schematic diagram illustrating an operation when the closed state is displaced to the opened state. FIG. 19 is a schematic diagram illustrating an operation when the open state is displaced to the closed state. FIG. 20 is a schematic view showing a special prize opening door as a modified example. In the following description, the vertical and horizontal directions will be described with reference to the state facing the front of the pachinko gaming machine 1.

  As shown in FIGS. 11 to 13, the special variable winning ball apparatus 20 includes a large winning unit 700 formed in a box shape and a decorative panel 701 that decorates the periphery of the special winning opening 20 a. A large winning opening 20a as an entrance for a horizontally-long rectangular game ball is formed on the front surface of the large winning unit 700, and a decorative panel 701 is formed in the decorative panel 701 for a large winning opening 701a. It is attached so that the grand prize opening 20a can be faced.

  The grand prize unit 700 has a base body 702 formed of a translucent synthetic resin material and a size capable of covering the upper surface of the base body 702, and is formed of a translucent synthetic resin material. The base cover 703 is mainly configured, and a hollow box is formed by assembling both.

  Inside the big prize unit 700, a door driving mechanism 705 for driving the big prize opening door 20b that opens and closes the big prize opening 20a, and a game ball to the big prize opening 20a when the big prize opening door 20b is in the retracted position. A restricting plate driving mechanism 706 for driving a restricting member 704 for restricting the entry of the player, a winning ball guiding passage 707 for guiding the game ball that has entered from the winning port 20a toward the discharge port formed on the back side, An LED board 708 provided with a plurality of large winning opening LEDs 708a that illuminate the winning ball guiding passage 707 from the back side, and a starting winning ball guiding passage 709 through which game balls that have entered the second starting winning opening 13b flow down (see FIG. 16). Are mainly disposed.

  The base body 702 includes a left disposition portion 710 that faces in the front-rear direction where the door drive mechanism 705 is disposed, a right disposition portion 711 that faces in the front-rear direction where the restriction plate drive mechanism 706 is disposed, and a left disposition portion. 710 and the right arrangement part 711 are formed in a substantially backward U shape in plan view from the middle arrangement part 712 arranged in the left-right direction so as to connect the 710 and the right arrangement part 711.

  The front side portion of the middle arrangement portion 712 is formed with notches 713 that constitute the left and right sides and the lower side of the big prize opening 20a formed on the front surface of the big prize unit 700, and from the notch 713, a big prize is formed. A ball guide passage 707 is continuously provided. The big winning ball guiding passage 707 has a horizontal width dimension substantially the same as the horizontal width of the notch 713, and is formed so that the rolling surface on which the game ball rolls widens toward the back side.

  The big winning ball guiding passage 707 is formed in a substantially concave shape facing backward in plan view, and a left passage 707a and a right passage 707b are formed on the left and right sides of the concave portion, and a rear side of the left passage 707a and the right passage 707b. Count outlets 23 and 23 are respectively installed in the outlets formed in the above, and the winning game balls are separately counted by the left and right count switches 23 and 23 and discharged downward. In addition, a passage wall 714 is erected around the big winning ball guide passage 707, and a guide inclined wall 714a for distributing game balls into a left passage 707a and a right passage 707b is provided in front of the concave portion. , 714b.

  The passage wall 714 is formed of a light-transmitting synthetic resin material, and allows light from the special prize opening LED 708a disposed on the back side thereof to be transmitted forward. Further, a through-passage 709a that constitutes a part of the start winning ball guiding passage 709 is formed in the concave portion partitioned from the big winning ball guiding passage 707 by the passage wall 714 so as to penetrate vertically.

  In this way, by forming the through path 709a so as to divide the big winning ball guiding passage 707 extending in the left-right width direction into the left and right, as shown in FIG. 16, it is arranged directly above the special variable winning ball device 20. Since the start winning ball guiding passage 709 extending downward from the variable winning ball device 15 does not have to be largely detoured to the back side so as to avoid the big winning unit 700, the variable winning ball device 15 is specially variable as much as possible. It can be arranged close to the winning ball device 20, and it is thereby possible to enlarge the effect display device 9 downward.

  Further, the winning ball guiding passage 707 extending in the left-right width direction is configured to be divided into a left passage 707a and a right passage 707b, so that the winning ball that has won the big winning opening 20a rolls in the left-right width direction. Therefore, the so-called over-winning can be avoided as much as possible.

  The base cover 703 is formed so as to be able to cover the upper surface of the base main body 702, and a through passage 709b is formed at a position corresponding to the through passage 709a.

It is mainly comprised from the support plates 721 and 722 erected on the left and right ends.

  A shaft hole 724L through which the swing shaft 723L is inserted is formed at the upper end portion of the left support plate 721, and a connecting shaft 725 projects outward from the rear side of the outer surface. A shaft hole 724R through which the swing shaft 723R is inserted is formed on the inner surface of the upper end portion of the right support plate 722. The left and right shaft holes 724L and 724R are concentric circles, and the swinging shafts 723L and 723R have an inner shaft 723a projecting inside the shaft holes 724L and 724R and an outer shaft 723b projecting outward each having substantially the same length. It is inserted to become.

  The rocking plate 720 has an upper surface disposed substantially parallel to the axis of the rocking shafts 723L and 723R. The upper surface of the rocking plate 720 includes the first inclined surface 720a and the first inclined surface 720a. The second inclined surface 720b is inclined with respect to the inclined surface 720a, and the third inclined surface 720c is inclined with respect to the second inclined surface 720b.

  The bottom surface (lower surface) of the rocking plate 720 includes a first bottom surface 720d that is inclined downward toward the rear and a second bottom surface 720e that is connected to the first bottom surface 720d and is inclined upward toward the rear, in front and rear in a cross-sectional view. A substantially central portion of the direction is formed in a downward angle that slightly protrudes downward, thereby constituting a curved surface formed along the circumferential surface centering on the swing shafts 723L and 723R. . A locking portion 726 extending in the left-right direction protrudes from the bottom front end portion.

  The restriction plate 730 has a lateral width dimension that is shorter than the separation width dimension of the support plates 721 and 722, and the vertical width dimension L2 is about half the separation width L1 from the shaft center to the swing plate 720. It consists of a horizontally long rectangular plate material (see FIG. 14).

  Cylindrical shaft holes 731L and 731R are formed along the upper side at the left and right ends of the upper side of the restriction plate 730, and the inner shaft 723a of the swinging shafts 723L and 723R is inserted, whereby the swinging shaft 723L. , 723R.

  A connecting piece 732 having a U-shape in a plan view is provided on the right side portion of the restriction plate 730 so as to open forward, and a connecting shaft 733 protrudes outward on the outer surface. When the connecting piece 732 is disposed so that the front surface of the regulating plate 730 is along the front side of the support plates 721 and 722, the connecting piece 732 is turned outward from the back side of the support plate 722, and the connecting shaft 733 is disposed at the front position. Can be set up.

  The large winning opening door 20b configured in this way is located on the left and right side upper portions of the notch 713 in the base body 702, that is, on the bearing portions 715a and 715b formed near the opening upper edge of the large winning opening 20a. With the outer shaft 723b pivotally supported, the swing plate 720 is retracted into the big prize opening 20a around the swing shafts 723L and 723R (see FIG. 14), and a big prize is won. It is pivotally supported so as to be able to swing back and forth between an advance position (see FIG. 15) that advances from the mouth 20a to the game area 7 side.

  On the other hand, the restricting member 704 is rotatably supported on the left and right sides via the inner shaft 723a with respect to the big prize opening door 20b, so that the restricting member 704 is located on the front surface of the big prize opening 20a around the swinging shafts 723L and 723R. A restriction position (see FIG. 14) that restricts the entry of the game ball so as to cover the half, and a non-regulation position that does not restrict (allow) the entry of the game ball by retreating from the restriction position into the big winning opening 20a. 15), and is pivotally supported so as to be able to swing back and forth.

  As shown in FIGS. 13 to 15, the door drive mechanism 705 is attached to the distal end of the plunger 21 a of the solenoid 21 and the solenoid 21 that drives the prize winning door 20 b, the solenoid winning door 20 b, and moves back and forth. It is mainly comprised from the moving member 740 and the connection member 741 which connects the moving member 740 and the special prize opening door 20b. The solenoid 21 is provided at a position corresponding to the left side portion of the big prize opening door 20b while the plunger 21a can move in the front-rear direction.

  The moving member 740 includes a mounting plate 740a that is mounted orthogonal to the tip of the plunger 21a, and a moving plate 740b that is provided continuously from the upper left edge of the mounting plate 740a and faces in the front-rear direction. A connecting hole 742 extending in the vertical direction is formed in the moving plate 740b.

  The connecting member 741 protrudes on the left and right side surfaces of the connecting plate 741a that rises in the front-rear direction and the left and right sides of the connecting plate 741a, and is supported by a bearing portion (not shown) formed in the left disposition portion 710. , A connecting shaft 741c that protrudes below the rotating shaft 741b on the outer surface of the connecting plate 741a and is inserted into the connecting hole 742, and a connecting shaft 741c across the rotating shaft 741b. The locking groove 741d is formed at the opposite end and locked to the connecting shaft 725.

  In the door drive mechanism 705 configured as described above, as shown in FIG. 14A, in the state where the solenoid 21 is not excited (solenoid 21; off), the plunger 21a is moved to the advanced position by the urging force of the coil spring 21b. Located in. In this state, the connecting hole 742 and the connecting shaft 741c are positioned on the front side with respect to the axial center of the rotating shaft 741b, so that the locking groove 741d at the front end rises obliquely upward and assumes a standing posture. 725 is pushed up, so that the swinging plate 720 is maintained at a retracted position in which the front side is disposed along the lower side of the special winning opening 20a and is inclined upward toward the back side.

  As shown in FIG. 15A, when the solenoid 21 is excited (solenoid 21; on), the plunger 21a moves (retreats) to the retracted position on the main body side against the biasing force of the coil spring 21b. When the moving member 740 moves to the main body side of the solenoid 21 together with the plunger 21a, the connecting shaft 741c fitted in the connecting hole 742 rotates around the axis of the rotating shaft 741b. As a result, the connecting member 741 rotates counterclockwise in FIG. 15A around the rotation shaft 741b, so that the locking groove 741d tilts and pushes down the connecting shaft 725, whereby the swing plate 720 is It is arranged so as to protrude from the special winning opening 20a to the outer game area 7, and is maintained at the advance position arranged to incline downward toward the back side.

  As shown in FIGS. 13 to 15, the restriction plate drive mechanism 706 is a movement that moves forward and backward attached to the restriction member 704, the solenoid 22 that drives the special winning opening door 20 b, and the plunger 22 a of the solenoid 22. It is mainly composed of a member 750, and a connecting member 751 that connects the moving member 750 and the special prize opening door 20b. The solenoid 22 is provided at a position corresponding to the right side portion of the special prize opening door 20b while the plunger 22a can move in the front-rear direction.

  The moving member 750 includes a mounting plate 750a that is mounted orthogonal to the tip of the plunger 22a, and a moving plate 750b that is provided continuously from the upper left edge of the mounting plate 750a and faces in the front-rear direction. A connecting hole 752 extending in the vertical direction is formed in the moving plate 750b.

  The connecting member 751 includes a connecting plate 751a, a left and right side surface of the connecting plate 751a, and a pivot shaft 751b facing in the left-right direction that is supported by a bearing portion (not shown) formed in the right disposition portion 711. The connecting shaft 751a protrudes above the rotating shaft 751b on the outer surface of the connecting plate 751a. The connecting shaft 751c is inserted into the connecting hole 752, and is formed at a location farther from the rotating shaft 751b than the connecting shaft 751c. And a locking groove 751d locked to 733.

  As shown in FIG. 14B, the restricting plate driving mechanism 706 configured as described above has the plunger 22a advanced by the biasing force of the coil spring 22b when the solenoid 22 is not excited (solenoid 22; off). Located in position. In this state, the connecting hole 752 and the connecting shaft 751c are positioned on the front side with respect to the axial center of the rotating shaft 751b, so that the locking groove 751d at the front end is tilted forward and tilted, thereby causing the connecting shaft 733. Thus, the restricting plate 730 is maintained in a restricting position in which the front face is disposed in a standing posture so that the front half covers the upper half of the special winning opening 20a.

  As shown in FIG. 15B, when the solenoid 22 is excited (solenoid 22; on), the plunger 22a moves (retreats) to the retracted position on the main body side against the biasing force of the coil spring 22b. When the moving member 750 moves to the main body side of the solenoid 22 together with the plunger 22a, the connecting pin 751c fitted in the connecting hole 752 is rotated around the axis of the rotating shaft 751b. As a result, the connecting member 751 rotates about the rotation shaft 751b in the clockwise direction in FIG. 15B, so that the locking groove 751d rises and pushes up the connecting shaft 733. It is retracted to the inside upper part of the winning opening 20a and is maintained in a non-restricted position that is substantially parallel to the swing plate 720 and does not restrict the entry of the game ball.

  In the present embodiment, the CPU 56 controls the solenoid 22 to rotate the regulating plate 730 from the regulated position to the non-regulated position when the solenoid 21 is used to swing the rocking plate 720 from the retracted position to the advanced position. When the solenoid 21 swings the swing plate 720 from the advanced position to the restricted position, the solenoid 22 performs control to rotate the restricting plate 730 from the non-restricted position to the restricted position. That is, interlocking control for rotating the regulating plate 730 according to the swing of the swing plate 720 is performed.

  Next, the operation of the special variable winning ball apparatus 20 configured as described above will be described with reference to FIGS.

  As shown in FIGS. 16 and 17, the big winning unit 700 is attached by being inserted into the big winning hole 760 formed in the game board 6 from the gaming area 7 side on the front. In a state where the big prize unit 700 is attached, a decorative panel 701 is arranged around the big prize opening hole 760 on the front surface 6a of the game board 6. Therefore, the big prize opening 20a as the entrance is opened to the front game area 7 at a predetermined position on the front surface 6a of the game board 6, that is, so as to open substantially orthogonal to the front surface 6a of the game board 6. It is formed.

  Further, the special winning opening 20a of the present embodiment is an entrance for a game ball provided so as to open substantially orthogonally to the front surface (game board surface) 6a of the game board 6, and is formed in the game board 6. Although it is formed on the front surface of the special winning unit 700 (structure) inserted into the special winning opening 760, it may be formed directly on the game board 6. Moreover, even if it does not open orthogonally with respect to the front surface 6a of the game board 6, it should just be formed so that it may cross and open.

  As shown in FIG. 16, in the closed state of the big prize opening 20a, the swinging plate 720 is disposed such that the front end side is along the lower side of the big prize opening 20a, and the retreat position is inclined upward toward the back side. In addition, the regulation plate 730 is maintained at a regulation position in which the front surface is disposed in an upright posture so as to cover the upper half of the special winning opening 20a.

  In this state, a gap is formed between the lower end of the restricting plate 730 and the front end of the upper surface of the swinging plate 720. As shown in FIG. Since it is shorter than the diameter 2R of the ball (L3 <2R), the game ball does not enter the inside through this gap. That is, the restricting plate 730 restricts the entry of the game ball into the special winning opening 20a.

  Therefore, the game ball flowing down from the upper position of the game area 7 is prevented from entering the special winning opening 20a, and the game ball falls on the swinging plate 720 in the closed state. Therefore, the swinging shafts 723L, 723R and the like are prevented from being damaged by the impact.

  Further, the locking portion 726 formed at the lower end of the swinging plate 720 facing the winning prize opening 20a is locked to the front end 707c of the winning winning ball guiding passage 707, so that the upper surface of the swinging plate 720 is secured. Since the game ball falling to the tip restricts the rotation of the swing plate 720 counterclockwise in FIG. 16, the swing plate 720 is rotated beyond the rotation range by contact with the game ball. It is possible to prevent the solenoid 21 and the like from being loaded.

  Furthermore, since the locking portion 726 is locked to the front end portion 707c, it is possible to avoid a gap between the swing plate 720 and the big winning ball guiding passage 707 at the retracted position. Since it becomes difficult to enter the member, it is possible to suppress an illegal act on the count switch 23 and the like for generating an illegal prize.

  Further, even when the restricting plate 730 does not move to the restricting position for some reason, the swinging plate 720 is inclined upward from the front end of the big winning ball guiding passage 707 toward the back side so as to be blocked in the guiding direction. Therefore, even if the game ball enters the special winning opening 20a, it is not guided to the discharge opening and detected by the count switch 23.

  Further, by disposing the front of the discharge port so as to cover the counter switch 23, it is possible to prevent an unauthorized member (such as a wire) or a thread hanging ball from entering the count switch 23.

  On the other hand, as shown in FIG. 17, in the open state of the big prize opening 20a, the swinging plate 720 is arranged so as to protrude from the big prize opening 20a to the game area 7 on the outer side, and downward toward the back side. In addition to being maintained at the inclined advance position, the restricting plate 730 is retracted to the inside upper part of the big prize opening 20a and is maintained at an unregulated position that is substantially parallel to the swing plate 720 and does not restrict the entry of the game ball. .

  The swinging plate 720 is disposed so as to incline downward toward the back side at the advanced position, so that the game ball that has fallen is guided toward the big prize opening 20a. In particular, the separation width dimension L5 between the back surface of the glass plate 102a formed on the glass door frame 102 and allowing the game area 7 to be seen through and the tip of the swinging plate 720 is shorter than the radius R of the game ball. Therefore, the game ball that has dropped near the back surface of the glass plate 102a can be reliably guided toward the big prize opening 20a.

  At this time, the restriction plate 730 in the retracted position is disposed substantially parallel to the swing plate 720 so that it does not interfere with the game ball flowing down the upper surface of the swing plate 720. The game balls that have dropped onto the winning ball guiding passage 707 from the upper surface of the swing plate 720 flow down on the winning ball guiding passage 707 and are guided to the discharge port, and then are counted and discharged by the count switch 23.

  Here, the action of the swing plate 720 and the regulating plate 730 during operation will be described with reference to FIGS. 18 and 19.

  As shown in FIG. 18, first, the case where the big prize opening door 20b is displaced from the closed state to the open state will be described. The swinging plate 720 is tilted forward toward the back side in the retracted position. However, after starting swinging toward the advance position, after the upper surface becomes substantially horizontal just before passing through the big prize opening 20a (see FIG. 18B), It gradually shifts to a backward leaning posture to the advance position.

  That is, the swing shafts 723L and 723R facing in the left-right direction are substantially parallel to the swing shafts 723L and 723R along the axial direction, and the upper surfaces 720a to 720c are centered on the swing shafts 723L and 723R. By being arranged along the peripheral surface, the posture of the upper surface is displaced according to the swing.

  In this embodiment, the tip of the swing plate 720 moves along the circumference centered on the swing shafts 723L and 723R, and the upper surface is displaced from the forward tilt to the rear tilt. Therefore, since the game ball falling from above is swung so as to be wound up and rescued from below, when the game ball collides before reaching the advance position, the game ball is moved downward. Since the rolling rotational force is applied, the game ball is easily guided toward the special winning opening 20a.

  Further, as the swinging plate 720 approaches the standing position with the rearward tilt angle increasing as it approaches the glass plate 102a, a game ball is sandwiched between the glass plate 102a and the swinging plate 720. It becomes difficult.

  Further, the regulation plate 730 is moved from the retracted position toward the advanced position from the retracted position to the retracted position, that is, in the direction opposite to the swing direction of the swing plate 720. Since the movement of the game ball in the same direction as the entry direction is started, the entry of the game ball is not hindered.

  Next, as shown in FIG. 19, the case where the special winning opening door 20b is displaced from the open state to the closed state will be described. The swing plate 720 is inclined backward to incline downward toward the back side at the advanced position. Since it is in the posture (see FIG. 19A), the game ball that has fallen is guided toward the big prize opening 20a, but by starting swinging toward the retreat position, the big prize opening is brought together with the game ball. Move towards 20a.

  In this case, the game ball on the upper surface enters the prize winning opening 20a as it is, but when the regulation plate 730 moves toward the regulation position, the game ball is pushed back toward the front. The entry of the sphere is restricted (see FIG. 19B). Further, since the upper surface of the swing plate 720 is displaced from the horizontal posture to the forward tilt posture, the game balls are discharged toward the game area 7 side. That is, even if the game ball enters the big winning opening 20a together with the swing plate 720, the game ball is forcibly returned to the game area 7 side by being displaced backward.

  Therefore, it becomes difficult for the game ball to enter when it is displaced to the closed state based on the fact that the closing condition of the special winning opening 20a is satisfied, so that the game ball wins after the round end condition is satisfied, that is, over Generation of winnings can be prevented.

  As described above, the CPU 56 executes the round game in which the special variable winning ball device 20 is in an open state, that is, the processes of steps S305 to S307, a predetermined number of times during the big hit game state. In each round game, when the maximum opening time of the grand prize opening elapses or when the number of winning prizes reaches the maximum prize winning number and the end condition of the round (the closing condition of the big prize opening 20a) is satisfied, the big prize opening 20a is closed. In order to set the state, the swing plate 720 is swung to the retracted position and the restricting plate 730 is moved to the restricting position.

  Here, when a game ball enters when the special winning opening 20a is closed, a predetermined time is required until the entered game ball flows down the winning ball guide passage 707 and is detected by the count switch 23. The round interval is set between the rounds so that the next round is not started until the award ball detection waiting time for detecting such a prize ball elapses. Specifically, the CPU 56 sets the prize winning hole closing time in step S416, and then sets a winning ball detection waiting time in step S418, and when the winning ball detection waiting time has elapsed (step S420; Yes). Then, the value of the special figure process flag is updated to “7”.

  In other words, the award ball detection waiting time elapses in order to count the game balls won after the round end condition is satisfied until the grand prize opening 20a is closed as the award balls over-win in the round. Until the next round game is started, the round interval is set so that it is not determined that the winning ball has been won.

  However, such a waiting time for the winning ball is set according to the length of the winning ball guiding passage 707 from the big winning opening 20a to the count switch 23. If it cannot be shortened, the waiting time for the prize ball also becomes longer. In such a case, since there is a limit to shortening the game period in the big hit gaming state by shortening the round interval, the operation of the gaming machine cannot be increased.

  Therefore, in the grand prize opening door 20b of the present embodiment, it becomes difficult for a game ball to enter from the time when the closing condition of the big prize opening 20a is established until it is closed, and the occurrence of over winning is reduced. Since the digestion time in the big hit gaming state can be shortened by shortening the interval as much as possible, the operation of the gaming machine can be enhanced.

  As described above, in the pachinko gaming machine 1 as an embodiment of the present invention, the swing plate 720 swings about the swing shafts 723L and 723R between the advanced position and the retracted position. Therefore, in order to forcibly move the swing plate 720 in the retracted position to the advanced position (for example, an illegal act of picking the swing plate 720 and pulling it out to the front side), the swing plate 720 must be pulled out along the circumferential direction. Since it is difficult to do so, it is possible to suppress the occurrence of illegal winnings.

  Further, since the swing plate 720 is suspended by swing shafts 723L and 723R rather than slides, the swing is affected even if the swing plate 720 is bent or deformed by an impact caused by the fall of the game ball. In addition, the frictional resistance generated at the time of operation is smaller than that of the slide type, so that the open / close operation failure is less likely to occur.

  In the embodiment, the swing shafts 723L and 723R are provided on bearing portions 715a and 715b formed in the vicinity of the upper side of the special winning opening 20a so as to be rotatable around the shaft center. At the advancing position, it is maintained in a rearward inclined posture that is inclined upward toward the direction away from the grand prize opening 20a (front), and at the retracted position, it is inclined downward toward the direction away from the big prize opening 20a (rear). By maintaining the forward tilt posture, the tilt angle of the swing ball 720 with respect to the falling direction of the game ball gradually decreases as the swing plate 720 moves from the retracted position toward the advanced position. That is, the game ball is swung up from below to be guided to the big prize opening 20a side, so that the game ball can be smoothly guided to the big prize opening 20a.

  Also, as shown in FIG. 20A, when moving from the advance position to the retracted position, the game ball moves from the big winning opening 20a by being reversely inclined (forwardly inclined) from the advance position. Since it is guided in the direction of outflow, the game ball is not drawn more than necessary and an over winning is not generated. That is, the swing plate 720 moves in the direction of being drawn into the special winning opening 20a, but gradually approaches the forward tilt, so that the game ball on the swing plate 720 is finally discharged to the game area 7 side. .

  In the present embodiment, the swinging plate 720 is arranged substantially line-symmetrically with respect to the big prize opening 20a at the advanced position and the retracted position, but the large plate shown in FIG. Like the prize opening door 200A, the advancing position and the retreat position may be arranged asymmetrically with respect to the big prize opening 20a.

  In this embodiment, the rocking shafts 723L and 723R of the rocking plate 720 are provided in the vicinity of the upper side of the big prize opening 20a. However, like the big prize opening door 200B shown in FIG. You may provide in the position (for example, back position) away from the upper side of the big prize opening 20a.

  Further, the swinging plate 720 is supported on both sides by a pair of support plates 721 and 722 provided from the swinging shafts 723L and 723R provided on both sides of the special winning opening 20a, respectively. The board restricts irregular game balls from entering from both the left and right sides of the special winning opening 20a (see FIG. 11B).

  In this embodiment, the swing plate 720 is suspended by a pair of left and right support plates 721 and 722 so as to be swingable. For example, a support plate provided at a central position in the left and right direction of the swing plate 720 is used. You may suspend so that it can rock | fluctuate through.

  Further, as shown in FIG. 14, the bottom surface of the rocking plate 720 is configured by a substantially curved surface that is curved in an arc shape around the rocking shafts 723L and 723R. Since the gap formed between the bottom surfaces 720d and 720e of the swing plate 720 and the lower side of the special winning opening 20a can be made as small as possible within the moving range, it is possible to avoid the entry of unauthorized equipment as much as possible.

  In the present embodiment, the bottom surface of the rocking plate 720 is configured by connecting the flat bottom surfaces 720d and 720e in a mountain shape when viewed from the side, but in this way, a plurality of flat surfaces are formed on the rocking shaft 723L, It may be a curved surface formed by being disposed along a circumference centered at 723R, or may be constituted by one continuous curved surface having a predetermined curvature.

  Further, by providing a restriction plate 730 that restricts the entry of the game ball into the special winning opening 20a when the swing plate 720 is in the retracted position, the game is performed when the swing plate 720 is retracted to the retracted position. It is possible to reliably prevent the ball from entering the winning opening.

  Further, in this embodiment, the restriction plate 730 is provided so as to be rotatable about the swing shafts 723L and 723R concentric with the swing plate 720, but is different from the swing shaft center of the swing plate 720. You may provide so that rotation centering on an axial center is possible. Alternatively, instead of rotating between the restriction position and the non-restriction position, for example, it may be linearly slid (for example, vertically moved). In this embodiment, the restricting member 704 is provided. However, such a restricting member 704 is not necessarily provided, and may be configured only by the big prize opening door 20b.

  The door drive mechanism 705 and the CPU 56 include a door drive mechanism 705 that drives the swing plate 720 and a restriction plate drive mechanism 706 that is provided separately from the door drive mechanism 705 and drives the restriction plate 730. The regulating plate drive mechanism 706 is linked to the swinging motion of the swinging plate 720 to move the regulating plate 730 to the regulation position for restricting the entry of the game ball to the big prize opening 20a and the game ball to the big prize opening 20a. Since the swing plate 720 and the regulating member are driven by separate drive sources by moving between the unregulated positions where the entry is not regulated, the structure is simplified.

  Next, the rendering device 500 will be described with reference to FIGS. FIG. 21 is a front view showing the rendering device. FIG. 22 is a rear view showing the rendering device. 23 is a cross-sectional view taken along the line CC of FIG.

The movable effect unit 502 and the drive mechanism 503 that drives the movable effect unit 502 are provided mainly.

  The movable effect part 502 is composed of a left movable part 502a and a right movable part 502b, and imitates a sword in a state where the left movable part 502a and the right movable part 502b are integrated with each other at the front position of the effect display device 9. A director is configured.

  An arc-shaped first guide groove 505 is formed in the guide plate 504 attached to the base plate 501, and an arc-shaped second guide groove 506 is formed below the first guide groove 505. It is formed substantially parallel to the first guide groove 505. A first guide roller 507 is slidably provided in the first guide groove 505, and a second guide roller 508 is slidably provided in the second guide groove 506.

  The first guide roller 507 is provided inside the upper portions of the left movable portion 502a and the right movable portion 502b, and the second guide roller 508 is provided outside the upper portions of the left movable portion 502a and the right movable portion 502b. Therefore, the left movable portion 502a and the right movable portion 502b are supported by the first guide groove 505 and the second guide groove 506 at the two upper portions via the first guide roller 507 and the second guide roller 508, respectively. Moving.

  In addition, drive arms 511a and 511b are provided on the guide plate 504 so as to be swingable around swinging shafts 510a and 510b facing in the front-rear direction. A long hole 512 is formed at the lower end of each of the drive arms 511a and 511b, and a support shaft 513 that is provided at a substantially central position in the vertical direction on the back of the left movable portion 502a and the right movable portion 502b is inserted. ing.

  In addition, restricting pieces 515a and 515b protrude from the lower ends of the drive arms 511a and 511b toward each other, and the restricting pieces are in a state where the left movable portion 502a and the right movable portion 502b are integrated. The tips of 515a and 515b are arranged so as to overlap in the front-rear direction.

  A driven gear 518 that meshes with a drive gear 517 fixed to the drive shaft of the drive motor 516 is formed on the upper portion of the drive arm 511a. Further, a driven gear 520 that meshes with the drive gear 517 via an intermediate gear 519 is formed on the upper portion of the drive arm 511b.

  In addition, auxiliary arms 520a and 520b are provided on the guide plate 504 so as to be swingable around swinging shafts 521a and 521b facing in the front-rear direction. A long hole 526 is formed at the lower end of each of the drive arms 511a and 511b, and a support shaft 527 that is provided at the lower back position of the left movable portion 502a and the right movable portion 502b and that faces in the front-rear direction is inserted.

  As shown in FIG. 24, in the rendering device 500 configured as described above, the left movable portion 502a and the right movable portion 502b are retracted in a state of being separated to the left and right sides of the rendering display device 9 ( 24 (a)), an effect position (see FIG. 24 (c)), which is arranged so as to be superimposed on the front of the display screen of the effect display device 9, and abuts each other's opposite sides. Are provided so as to be able to swing back and forth.

  Specifically, when the rotational force of the drive gear 517 of the drive motor 516 is transmitted to the driven gears 518 and 520, the drive arms 511a and 511b rotate about the swing shafts 510a and 510b, so that the left movable portion 502a and the right movable part 502b are moved in the left-right direction along the first guide groove 505 and the second guide groove 506, respectively.

  Thus, when only a part (for example, the upper part) of the left movable part 502a and the right movable part 502b is guided in a cantilever state with respect to the guide plate 504 and the like, the other part (for example, the lower part) side is a guide. When moving in the left-right direction, the back-and-forth direction rattling is likely to occur when moving in the left-right direction.

  However, since the restricting pieces 515a and 515b are arranged so as to overlap in the front-rear direction at the production position, the relative movement in the front-rear direction of the left movable part 502a and the right movable part 502b is restricted by contact, so the front-rear direction Is prevented from being displaced.

  Further, the restriction pieces 515a and 515b are not provided so as to protrude in advance from the inner sides of the left movable portion 502a and the right movable portion 502b, but are formed on the drive arms 511a and 511b. As shown in FIG. 24, in the retracted position, it is hidden behind the left movable part 502a and the right movable part 502b, so that it is not visible, but gradually protrudes toward the effect position, Since it contacts on the back side, the appearance is not impaired.

  In the present embodiment, such restricting pieces 515a and 515b are formed on the drive arms 511a and 511b as examples of the movable parts that move according to the movement of the left movable part 502a and the right movable part 502b. As long as it is a movable part that can move according to the movement of the left movable part 502a and the right movable part 502b, it may be formed in a movable part other than the one that drives the left movable part 502a and the right movable part 502b.

  Next, a special variable winning ball apparatus 20 'as a modification of the present invention will be described with reference to FIGS. FIG. 25 is a perspective view showing a special variable winning ball apparatus as a modification of the present invention. FIG. 26 is an exploded perspective view showing the internal structure of the special variable winning ball apparatus shown in FIG. 27A is a perspective view showing a closed state of the big prize opening door of FIG. 25, and FIG. 27B is a perspective view showing an opened state. In the following description, the same components as those of the special variable winning ball apparatus 20 of the above-described embodiment are denoted by adding 100 to the reference numerals attached to the special variable winning ball apparatus 20, and detailed description thereof is omitted. To do.

  The special variable winning ball apparatus 20 ′ according to the present modification differs from the special variable winning ball apparatus 20 of the above embodiment in that the swing plate 820 and the regulating plate 830 are connected by a single solenoid 21A via an interlocking mechanism. It is a point to be linked.

  Specifically, as shown in FIGS. 25 to 27, the drive mechanism 870 includes a big prize opening door 20b, a solenoid 21A that drives the big prize opening door 20b, and a tip of a plunger (not shown) of the solenoid 21A. A moving member 871L attached to the front and rear, a moving member 871R disposed on the opposite side of the moving member 871L across the prize winning door 20b, and a connecting link 872 connecting the moving members 871L and 871R. Mainly composed.

  The moving members 871L and 871R are guided so as to be slidable in the front-rear direction with respect to the base body 802, and the vertically long connection into which the connecting shaft 833 formed on the outer surface of the restriction plate 830 is inserted into the left moving member 871L. A hole 834 is formed, and a vertically long connecting hole 826 into which the connecting shaft 825 formed in the swing plate 820 is inserted is formed in the right moving member 871R.

  The connecting link 872 has a shaft hole 873 formed in the center in the longitudinal direction inserted into a rotation shaft (not shown) formed on the upper surface of the base cover 803 and directed in the vertical direction. The left end is pivotally supported by a connecting shaft 874L protruding from the upper surface of the moving member 871L, and the right end is pivoted by a connecting shaft 874R protruding from the upper surface of the moving member 871R. It is supported.

  Therefore, in the open state of the big prize opening door 20b, the solenoid 21A is in a non-excited state, and the plunger (not shown) is biased forward, so the moving member 871L is positioned at the front position. On the other hand, the moving member 871R is located at the rear position by the connecting link 872. Here, since the connecting shaft 833 is pushed forward when the moving member 871L is located at the front position, the restricting plate 830 stands upright at the restricting position, and the connecting shaft 825 is located when the moving member 871R is located at the rear position. Since it is pulled out rearward, the swinging plate 820 is inclined forward at the retracted position.

  In the closed state of the special prize opening door 20b, the solenoid 21A is in an excited state, so that the plunger (not shown) is pulled back, so that the moving member 871L is located at the rear position, whereas the moving member 871R is located in the front position by the connecting link 872. Here, since the connecting shaft 833 is pulled out rearward when the moving member 871L is at the rear position, the restricting plate 830 is tilted at the non-restricting position, and the connecting shaft 825 is when the moving member 871R is at the front position. Is pushed forward, the swinging plate 820 is tilted backward at the advanced position.

  As described above, the swing plate 820 and the restriction plate 830 may be interlocked via the connection link 872 that is an interlocking mechanism by one drive source (for example, the solenoid 21A). In this way, the rocking plate 820 and the regulating plate 830 can be driven by a single drive source, and can be linked by a mechanical linkage mechanism. The interlock control load can be reduced.

  In this modification, the connecting link 872 and the like are described as the interlocking mechanism. However, if the restricting plate 730 can be moved up and down in conjunction with the driving of the swinging plate 720, the connecting link is not used. Further, it may be interlocked via another interlocking mechanism (not shown) such as a gear mechanism.

  FIG. 28 is a front view showing special variable winning ball apparatuses 20A to 20D as another modification of the present invention.

  In the above-described embodiment, the restriction plate 730 is formed in a horizontally long rectangular shape, and is arranged such that the lower end side 730a is substantially parallel to the upper surface (first inclined surfaces 720a to 720c) of the swing plate 720 at the restriction position. However, you may form so that it may become non-parallel with respect to the upper surface (the 1st-3rd inclined surface 720a-720c) of the rocking | swiveling board 720. FIG.

  For example, as shown in the special variable winning ball apparatus 20A, the lower end side 730a of the restricting plate 730 may be formed in a mountain shape so that the substantially center position in the longitudinal direction protrudes downward (see FIG. 28A). .

  Further, as shown in the special variable winning ball apparatus 20B, the lower end side 730a of the regulation plate 730 may be formed in a valley shape so that the substantially center position in the longitudinal direction is recessed upward (see FIG. 28B). .

  Further, as shown in the special variable winning ball apparatus 20C, the lower end side 730a of the regulation plate 730 may be formed in a curved shape so that the substantially central position in the longitudinal direction bulges downward (FIG. 28 (c)). reference).

  Further, as shown in the special variable winning ball apparatus 20D, not the lower end side 730a of the restricting plate 730 but the substantially central position in the longitudinal direction on the upper surface (for example, the first to third inclined surfaces 720a to 720c) of the swing plate 720. May be formed in a mountain shape so as to protrude upward (see FIG. 28D).

  Thus, by arranging the lower end side 730a of the regulating plate 730 to be inclined in the longitudinal direction (non-parallel) with respect to the upper surface of the swing plate 720, for example, the regulating plate 730 is moved from the retracted position to the regulated position. Even when the game ball P caught in the swing plate 720 retracted toward the retreat position enters the space between the lower end side 730a of the regulating plate 730 and the upper surface of the swing plate 720 when moving toward the retracted position, the lower end side 730a Is inclined with respect to the upper surface of the swing plate 720, so that the game ball P can easily escape to the wider side of the frontage, so that the game ball is between the lower end side 730a and the upper surface of the swing plate 720 during the closing operation. P or the like bites and does not hinder the movement of the swing plate 720, the restriction plate 730, and the like.

  Note that the vertical width dimension L3 (see FIG. 14A) between the upper surface of the swinging plate 720 and the lower end side 730a of the regulating plate 730 at the regulated position is shorter than the radius R of the game ball P. (L3 <R), it becomes difficult for the game ball P to enter between the lower end side 730a and the upper surface of the swing plate 720, but if the vertical width L3 is too small, the regulation plate 730 becomes longer and swings during operation. There is a risk of contact with the plate 720. Accordingly, when the vertical width dimension L3 cannot be made shorter than the radius R of the game ball P due to the structure, the lower end side 730a of the restriction plate 730 is in the longitudinal direction with respect to the upper surface of the swing plate 720 as described above. It is preferable to arrange it so as to incline (non-parallel).

  In the above embodiment, the example in which the present invention is applied to the special variable winning ball apparatus 20 has been described. However, the present invention can also be applied to the variable winning ball apparatus 15 and other winning holes.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  In the above embodiment, a spherical pachinko ball (game ball) is applied as an example of a game medium. However, the present invention is not limited to a spherical game medium. For example, a non-spherical game medium such as a medal is used. There may be.
