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. In other words, 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. In addition, the first special symbol display 8a and the second special symbol display 8b each variably display a number (or a two-digit symbol) of 00 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 variation display of the first special symbol is a variation display start condition (for example, after the game ball has won the first start winning opening 13a) after the first start condition that is the execution condition of the variation display is established (for example, When the number of reserved memories is not 0, the first special symbol variation display is not executed and the big hit game is not executed), and the variation display is started. When time (fluctuation time) elapses, a display result (stop symbol) is derived and displayed. In addition, the variation display of the second special symbol is a variation display start condition (for example, that the game ball has won the second start winning opening 13b) after the second start condition, which is the execution condition of the variation display, is established ( For example, when the number of reserved memories is not 0, the second special symbol variation display is not executed, and the big hit game is not executed) is started, When the fluctuation display time (fluctuation time) elapses, a 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). The change display of the first special symbol on the first special symbol display 8a and the change display of the effect symbol on the effect display device 9 are synchronized. Further, the variation display of the second special symbol on the second special symbol display 8b and the variation display of the effect symbol on the effect display device 9 are synchronized. Synchronous means that the start point and end point of variable display are substantially the same (may be exactly the same) and the period of variable display is substantially the same (may be exactly the same). In addition, 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 causes the jackpot to be recalled. 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 that has won the first start winning opening 13a is guided to the back of the game board 6 and detected by the first start opening switch 14a.

  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. 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 device 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.

  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 18 including a 7 segment LED + 1 segment LED provided with a symbol reservation storage 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. And whenever the fluctuation | variation display by the 2nd special symbol display 8b is started, the number of the indicators to light is reduced by one. In this example, the upper limit number (up to 4) is provided for the start memory number by winning to the first start winning port 13a and the start memory number by winning to the second start winning port 13b. May be four or more.

  Further, the display screen 9a of the effect display device 9 is provided with a first reserved memory display unit 18c for displaying the first reserved memory number and a second reserved memory display unit 18d for displaying the second reserved memory number. Yes. 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 unit for displaying the total number is provided, it is possible to easily grasp the total number of execution conditions that have not met the variable display start condition.

  In this embodiment, as shown in FIG. 1, there is provided a variable winning ball device 15 that opens and closes only the second starting winning opening 13b. However, the first starting winning opening 13a and the second starting winning opening 13b are provided. A configuration in which a variable winning ball apparatus that performs an opening / closing operation may be provided for any of the winning openings 13b.

  Further, as shown in FIG. 1, a special variable winning ball device 20 is provided below the variable winning ball device 15. The special variable winning ball apparatus 20 includes a big prize opening door, and when a specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a, and on the second special symbol display 8b, a specific display result (big hit) In the specific game state (big win game state) that occurs when the symbol is derived and displayed, the solenoid 21 controls the open door of the big winning opening, so that the big winning opening that becomes the winning area is opened. The game ball that has won the big winning opening is detected by the count switch 23.

  Based on the detection of 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) through the large winning opening which has been opened in the special variable winning ball apparatus 20, other game winning holes such as the first starting winning opening 13a and the second starting winning opening 13b are played. More prize balls are paid out than when the ball passes (enters). Therefore, if the special prize winning ball device 20 is in the open state in the special variable winning ball apparatus 20, the 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 ball device 20, the game ball cannot be passed through (entered) into the special prize opening to obtain a prize ball, which is disadvantageous for the player. It becomes a state.

  The normal symbol display 10 is provided on the right side of the first special symbol display 8a. The normal symbol display 10 is composed of two lamps, for example. When the game ball passes through the gate 32 and is detected by the gate switch 32a, the display variation of the normal symbol display 10 is started. In this embodiment, the upper and lower lamps (the symbols can be visually recognized at the time of lighting) are alternately turned on to perform the variable display. 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). ). On the upper part of the special symbol storage memory display 18, a normal symbol storage memory display 41 having four display portions (for example, four segments of 7 segments LED + 1 segment LED) for displaying the number of winning balls passed through the gate 32. Is provided. 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 on 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 storage display 41 composed of 7 segment LED + 1 segment LED has four display sections (segments) for displaying the number of winning balls that have passed through the gate 32 and, for example, the special variable winning ball apparatus 20 at the time of big hit. There are two display sections (segments) that indicate the number of times of opening (number of big hit rounds), and two display sections (segments) that indicate the gaming state, but these display sections are separate from the normal symbol hold storage display section. You may comprise with a display. Further, the normal symbol display 10 may be configured by segment LEDs or the like capable of variably displaying a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  In the vicinity of the special variable winning ball apparatus 20, winning holes 29a to 29d of the normal winning apparatus are provided, and game balls that have won the winning holes 29a to 29d are detected by the winning hole switches 30a and 30b. Each of the winning holes 29a to 29d constitutes a winning area provided in the game board 6 as an area for accepting game balls and allowing winning. The first start winning opening 13a, the second start winning opening 13b, and the big winning opening also constitute a winning area that accepts game balls and allows winning.

  On the left side of the game area 7, there is provided a decoration member 25 having a decoration LED 25a that blinks and displays during the game, and there is an out port 26 for absorbing a game ball that has not won a prize. In addition, four speakers 27 that emit sound effects are provided on the left, right, top, and bottom of the outside of the game area 7. On the outer periphery of the game area 7, a top frame LED 28a, a left frame LED 28b, and a right frame LED 28c are provided. The top frame LED 28a, the left frame LED 28b, the right frame LED 28c, and the decoration LED 25a are examples of a decoration light emitter provided in the gaming machine.

  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, the first special symbol variation display can be started (for example, the special symbol variation display ends, 1), the first special symbol display unit 8a starts the variable display (variation) of the first special symbol, and the effect display device 9 starts the variable display of the effect symbol (decorative symbol). Is done. That is, 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 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 variation display of the second special symbol can be started (for example, the variation display of the special symbol ends, 2), the second special symbol display unit 8b starts the variation display (variation) of the second special symbol, and the effect display device 9 starts the variation display of the effect symbol (decoration symbol). Is done. That is, the change 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 variation display of the first special symbol on the first special symbol display 8a and the variation display of the second special symbol on the second special symbol display 8b are stopped when a certain time has passed. If the special symbol at stop (stop symbol) is a big hit symbol (specific display result), it will be “big hit”. If the special symbol at stop (stop symbol) is displayed differently from the big hit symbol, "

  After the fluctuation 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.

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

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

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

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

  In the “left”, “middle”, and “right” effect symbol display areas provided in the effect display device 9, a 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 8b, the production symbol variation display (variation display) is started. In the period from the start of the variation display of the effect symbol to the end of the variation display due to the stop display of the confirmed effect symbol in the “left”, “middle”, and “right” effect symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state refers to an effect design (“reach” that is not yet displayed as a temporary stop when the effect design temporarily displayed in the display area of the effect display device 9 forms part of the jackpot combination. "Varying symbols" refers to the display state in which the variation continues, or the display state in which all or part of the design symbol is changing synchronously while constituting all or part of the jackpot combination. is there. Specifically, a part of the “left”, “middle”, and “right” effect symbol display areas (eg, “left” and “right” effect symbol display areas) constitutes a predetermined jackpot combination. In the remaining effect symbol display area (for example, “medium” effect symbol display area, etc.) that has not yet been temporarily stopped when the effect symbol (for example, an effect symbol indicating “7” alphanumeric characters) is temporarily stopped. The display state in which the effect symbol is fluctuating, or the effect symbol synchronizes with all or part of the effect symbol display area of the “left”, “middle”, and “right” while constituting all or part of the jackpot combination The display state is fluctuating.

On the power supply board (not shown), the main board 31 and each electric component control board (the effect control board 80 and the payout control board 37) in the pachinko gaming machine 1 and each electric component (power is supplied) provided in the pachinko gaming machine 1 are shown. A power switch as a power supply permission means for executing or cutting off power supply to a component that operates by being supplied, and a clear switch for clearing the RAM 55 of the game control microcomputer 156 of the main board 31 are provided. It has been. Further, a replaceable fuse is provided inside the power switch (inside the substrate).

  In this embodiment, the main board 31 is provided on the game board side, and the payout control board 37 is provided on the game frame side. Even in such a configuration, as will be described later, the communication between the main board 31 and the payout control board 37 is performed by serial communication, thereby facilitating the routing of the wiring when replacing the game board. .

  Each control board is equipped with control means including a control microcomputer. The control means is an electrical component (game device: ball payout device 97, effect display device 9, light emission from a lamp, LED, etc.) provided in the gaming machine according to a command signal (control signal) as a command from the game control means or the like. Body, speaker 27, etc.). Hereinafter, the main board 31 may be included in the control board for explanation. In that case, the control means mounted on the control board refers to each of the game control means and the means for controlling the electrical components provided in the gaming machine in accordance with a command signal from the game control means or the like. A substrate on which a microcomputer other than the main substrate 31 is mounted may be referred to as a sub-substrate. The ball payout device 97 is a device for paying out a game ball guided by a passage for guiding a 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. The terminal board 91 includes, for example, information output signals such as jackpot information indicating the occurrence of a jackpot gaming state (start signal, symbol determination frequency 1 signal, jackpot 1 signal, jackpot 2 signal, jackpot 3 signal, time reduction signal, security An information output terminal for externally outputting a signal, a prize ball signal 1, a gaming machine error state signal, etc. is provided. It should be noted that the gaming machine error status signal does not necessarily have to be output to the outside of the pachinko gaming machine 1, and a door indicating that the gaming frame is open from the information output terminal instead of the gaming machine error status signal. An open signal or the like may be output.

  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 the program stored in the ROM 54, so that 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 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 the display result of the special symbol variation 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 jackpot display result as a specific display result based on the random R, that is, whether or not to make a jackpot display result. 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 become operable, and when the reset signal becomes low level, the game control microcomputer 156 and the like become inoperative. 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, an input driver circuit 58 for providing the basic circuit with detection signals from the gate switch 32a, the first start port switch 14a, the second start port switch 15a, the count switch 23 and the winning port switches 30a and 30b is also mounted on the main board 31. A solenoid 16 for opening and closing the variable winning ball apparatus 15, a solenoid 21 for opening and closing the special variable winning ball apparatus 20, and an output circuit 59 driven in accordance with a command from the basic circuit are also mounted on the main board 31, and game control is performed when the power is turned on. A system reset circuit (not shown) for resetting the microcomputer 156 for the game, and an information output signal such as jackpot information indicating the occurrence of the jackpot gaming state to an external device such as a hall computer via the terminal board 91 The information output circuit 64 that outputs the information is also mounted on the main board 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 is performed with the effect display device 9 that variably displays the effect symbol.

  The effect control board 80 is equipped with an effect control microcomputer (not shown) including an effect control CPU 120 and a RAM (not shown). The RAM may be externally attached. In the effect control board 80, the effect control CPU 120 operates in accordance with a program stored in a built-in or external ROM (not shown), and receives a capture signal (effect) from the main board 31 input via the relay board 77. In response to the control INT signal), an effect control command is received via the input driver and the input port. Further, the effect control CPU 120 causes the VDP (video display processor) 262 to perform display control of the effect display device 9 based on the effect control command.

  The effect control CPU 120 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. The effect control CPU 120 outputs the data read from the character ROM to the VDP. The VDP 262 performs display control based on data input from the effect control CPU 120.

  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).

  Furthermore, the effect control CPU 120 outputs signals for driving various LEDs to the lamp driver board 35 via an output port (not shown). Also, the sound number data is output to the voice control board 70 via the output port.

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver 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).

The main board 31 is attached to the front surface of the cover member 202 with the mounting surface on which electronic components or the like are mounted (mounted) facing the front surface of the cover member 202, and in the attached state, the front surface is the side walls 202b to 202d. It is accommodated so as to be located on the back side with respect to the front end.

  When the base member 201 and the cover member 202 are sealed, as shown in FIG. 10, the main substrate 31 is attached to the front surface side of the cover member 202 via an attachment screw 238. In this way, by housing the main board 31 in a state where the mounting surface is covered on the front surface side of the cover member 202, even if the cover member 202 is illegally opened, the cover member 202 can be removed from the main surface. Unless the substrate 31 is removed, it becomes impossible to perform an illegal act on the electronic components such as the CPU 56 and the ROM 54 mounted on the mounting surface.

  Next, the front surface of the main board 31 attached to the front surface side of the cover member 202 is opposed to the back surface of the base plate 201 a of the base member 201, and each engagement piece 220 of the cover member 202 is engaged with each engagement groove 250 of the base member 201. Is inserted and slid as shown by an arrow in the figure. When each engagement piece 220 comes into contact with the end of each engagement groove 250 and the sliding movement is restricted, the engagement pieces 203 and 203 of the base member 201 are inserted into the insertion holes 222 and 222 on the right short side. It is inserted inside. As described above, the engagement pieces 220 are engaged with the engagement grooves 250, and the locking pieces 203 and 203 are inserted into the insertion holes 222 and 222, whereby the cover member 202 is assembled to the base member 201. As a result, the assembly position of the cover member 202 with respect to the base member 201 is determined, the base member 201 and the cover member 202 are aligned, and the opening of the base member 201 is closed (locked state). It becomes possible.

  Next, the cover-side welded portion 223 and the base-side welded portion 207 which are welded portions are welded (caulked) (also referred to as a first sealed state), and the one-way screw 240c attached to the attachment sealing piece 290 is screwed into the screw hole 210. Screw in. In addition, the closing screw 226 is generally composed of a rod-like portion having a male screw portion (attachment portion) formed on the outer periphery and a head portion formed at one end of the rod-like portion and housed in the recess 227 of the screw covering piece 261. A screw is inserted into the mounting hole 227a of the recess 227 and inserted into the screw hole 209, and then sealed so as to straddle the cover side sealing part 224 and the base side sealing part 229. A U-shaped seal protective cover 228 made of a synthetic resin material is provided so as to cover the adhered seal seal 291 while forming a sealed state (also referred to as a second sealed state or a sealed state) by attaching 291. The cover member 202 and the base member 201 are mounted so as to be sandwiched therebetween, and the seal seal 291 is protected.

  Thus, in the state where the locking pieces 203, 203 formed on one short side 201c of the base member 201 are locked to the insertion holes 222, 222 of the cover member 202, the cover side welding of the other short side 201d is performed. The portion 223 and the base-side welding portion 207 are welded (fixed) to each other, and the one-way screw 240c attached to the attachment sealing piece 290 is screwed into the screw hole 210, whereby the cover member 202 slides relative to the base member 201. A sealed state is formed in which the movement is restricted and the upper surface of the base member 201 is closed by the cover member 202. In this sealed state, both the cover-side welded portion 223 of the cover member 202 and the welded portion of the base-side welded portion 207 of the base member 201 are cut (broken), and the attachment sealing piece 290 is cut from the cover member 202, Further, since it cannot be released unless the seal seal 291 is broken, when the cover member 202 is opened, the trace, that is, the trace that the part of the main board case 200 is destroyed is surely left. It is easy to find out that there is a possibility that some kind of fraud has been performed on the main board 31 stored in the main board case 200.

  In this embodiment, the main board case 200 is sealed so that it is easy to find that there is a possibility that some improper acts have been performed on the main board 31 when the main board case 200 is opened. However, such sealing may be performed by at least one of the sealing means even if it is not performed by all the sealing means of the welding, the one-way screw 240c, and the sealing seal 291. The sealing means may be a sealing member other than these. Further, the main substrate case 200 may not necessarily be sealed.

  Next, how the main board case 200 is attached to the attachment portion 420 will be described with reference to FIGS. 11 to 16, only the base cover 410 and the cover door 302 of the effect unit 300 are illustrated, and other components included in the effect unit 300 and the panel board 400 are omitted. The game unit 6 is constructed by assembling the production unit 300 on the back surface of the board surface plate 400, and when the game board 6 constructed in this way is attached to the front frame 101 and from the front frame 101, Even when it is removed, it will be described as being in the situation described below.

  As shown in FIGS. 11 and 12, when the main board case 200 in which the main board 31 is housed is attached to the attachment part 420 or removed from the attachment part 420, the cover door 302 is attached to the back plate 410e of the base cover 410 and not shown. The main board case 200 is attached to the attachment part 420 from the back side in the intermediate position (see FIG. 15) substantially orthogonal to the panel board 400 or with the cover door 302 removed from the base cover 410.

  Specifically, first, with the locking pieces 230a to 230c protruding from the front surface of the base member 201 facing the mounting portion 420, the bent pieces 232 of the locking pieces 230a to 230c correspond to the corresponding locking pieces. The main board case 200 is pushed toward the mounting portion 420 so as to be inserted into the long hole portions 423 of the holes 422a to 422c (see FIG. 11A). At this time, as shown in FIG. 12 (A), the main board case 200 is disposed at the attachment / detachment position on the left side of the mounting portion 420, and the front surface of the base member 201 approaches or contacts the back plate 410e. Further, the engagement piece 430 is covered with the base member 201 and is pushed forward by elastic deformation.

  Next, the main board case 200 is slid to the right along the back plate 410e (see FIG. 11B). By this sliding movement, the horizontal piece 231 of each of the locking pieces 230a to 230c is inserted into the groove 424, and the bent piece 232 is locked to the periphery of the groove 424 on the front surface of the back plate 410e (FIGS. 12B and 12C). As a result, the main substrate case 200 is restricted from being detached from the attachment portion 420 at the attachment position, and the engagement portion 431 of the engagement piece 430 is exposed to the back side, so that the main substrate case 200 is engaged with the engagement portion. Since the engaging piece 430 swings to the back side due to the elastic return force, the engaging portion 431 protruding to the back side from the back plate 410e is engaged with the left side of the main board case 200. In this case, the sliding movement of the main board case 200 to the left is restricted.

  In other words, the main board case 200 is slid from the left attachment / detachment position to the right attachment position of the attachment portion 420, and the attachment to the attachment portion 420 is restricted by the locking pieces 230a to 230c at the attachment position. At the same time, since the sliding movement to the attachment / detachment position side is restricted by the engagement portion 431, the engagement portion 431 is held at the attachment position. Further, in order to remove the main board case 200 from the attachment portion 420, the main board case 200 is moved to the attachment / detachment position while pushing the engagement portion 431 on the left side of the main board case 200 to the front side in the attachment position to release the engagement state. By slidably moving toward the attachment / detachment position, the engagement state by the engagement pieces 230a to 230c is released, whereby the main board case 200 can be detached from the attachment portion 420 and removed.

  That is, even when the main board case 200 is slidably movable by being released from the engagement portion 431 at the attachment position, the main board case 200 is released from the engagement state by the engagement pieces 230a to 230c. As long as it is not slid to the end, it cannot be detached from the attachment portion 420 and removed.

  Next, the relationship between the main board case 200 attached to the attachment part 420 and the cover door 302 will be described with reference to FIGS.

  As shown in FIG. 13A, in the state where the cover door 302 is in the closed position where the opening 411 is closed, the effect movable device (not shown) accommodated inside the base cover 410 and the effect display device 9 ( Various effect devices (game devices) such as an effect control board case 500 and a relay board (not shown) are covered. Thereby, in a state where the pachinko gaming machine 1 is disposed on a gaming machine installation island (not shown) installed in a gaming store or the like, for example, a game ball circulating in the gaming machine installation island (not shown) or a structure Protects against falling objects such as screws screwed into objects colliding with the production device (game device) or being damaged by colliding with structures etc. when the pachinko gaming machine 1 is installed Is done.

  Further, a part of the lower side portion of the cover door 302 is formed with an upper side portion on the back surface of the main board case 200 disposed at the attachment position in the attachment portion 420, specifically, a recess in which the connector openings 236a to 236g are formed. 202e is covered from the back side. Therefore, since the wiring side connectors (not shown) connected to the board side connectors CN1 to CN7 facing the respective connector openings 236a to 236g are covered, damage or removal due to collision of falling objects such as game balls is prevented. Is done. In addition, in the connector opening 236a, the notch recess 320 is disposed so that it is exposed to the back side.

  As shown in FIG. 13B, when the cover door 302 is in the closed position, the restriction piece 322 of the cover door 302 is regulated so as to extend in the up-down direction protruding from the left end of the recess 202e of the cover member 202. It arrange | positions so that the left side of the part 280 may be opposed. Specifically, when the main board case 200 is slid from the attachment position toward the left attachment / detachment position, the restricted portion 280 is arranged so that the right end surface of the bent piece 322b of the restriction piece 322 contacts the restricted portion 280. On the other hand, it arrange | positions so that the right end surface of the bending piece 322b may leave | separate only the predetermined clearance L12.

  As shown in FIG. 12A, the gap L12 is shorter than the left-right width L11 of the groove 424 of the locking holes 422a to 422c (L12 <L11). Here, the left-right width dimension L11 of the groove 424 is the minimum length necessary for releasing the locking state by the locking pieces 230a to 230c, that is, for moving the main board case 200 from the mounting position to the mounting / removing position. is there. Therefore, by making the gap L12 shorter than the left-right width dimension L11, the right end surface of the bent piece 322b of the restriction piece 322 becomes the restricted portion 280 before the main board case 200 reaches the attachment / detachment position from the attachment position. The sliding movement is regulated by contact (contact). That is, when the cover door 302 is in the closed position, the right end surface of the bent piece 322b of the regulating piece 322 abuts (contacts) the regulating board 280 while the main board case 200 is slid from the attachment position to the attachment / detachment position. Thus, the slide movement is restricted, and the main board case 200 cannot be removed from the attachment portion 420 because it cannot be moved to the attachment / detachment position.

  Next, as shown in FIG. 14A, in the state where the cover door 302 is in the open position where the opening 411 is opened, the effect movable device (not shown) housed in the base cover 410, the effect display Part of various effect devices (game devices) such as the device 9 (not shown), the effect control board case 500, and the relay board (not shown) are exposed to the back side through the opening 411. Moreover, the recessed part 202e which was covered with the back upper side part of the main board case 200 by a part of the lower side part of the cover door 302 is opened to the back side, and the connector openings 236a to 236g are exposed.

  Further, as shown in the enlarged view in FIG. 14A and FIG. 14B, when the cover door 302 is in the open position, the edge of the notch 325 on the inclined edge 306 of the cover door 302 is It arrange | positions so as to oppose the left side of the to-be-regulated part 281 formed in the left end. Specifically, when the main board case 200 is slid from the attachment position toward the left attachment / detachment position, the restricted portion 281 is in contact with the restricted portion 281 so that the edge of the notch 325 on the inclined edge 306 contacts the restricted portion 281. The inclined edge 306 is arranged so that the edge of the notch 325 is separated by a predetermined gap L13.

  The gap L13 is shorter than the left-right width dimension L11 of the groove 424 of the locking holes 422a to 422c (L13 <L11). In this way, by making the gap L13 shorter than the left-right width dimension L11, the edge of the notch 325 in the inclined edge 306 reaches the regulated portion 281 before the main board case 200 reaches the attachment / detachment position from the attachment position. The sliding movement is regulated by contacting (contacting) the surface. That is, when the cover door 302 is in the open position, the edge of the notch 325 in the inclined edge 306 contacts (contacts) the regulated portion 280 while the main board case 200 is slid from the attachment position to the attachment / detachment position. Therefore, the slide movement is restricted and the main board case 200 cannot be removed from the attachment portion 420 because it cannot be moved to the attachment / detachment position.

  Next, as shown in FIG. 15A and FIG. 16A, an intermediate position (specification) in which the cover door 302 is in the middle between the closed position and the open position substantially orthogonal to the back plate 410e and the panel board 400. Even in the state of the position, a variety of effects such as an effect movable device (not shown), an effect display device 9 (not shown), an effect control board case 500, a relay board (not shown) housed in the base cover 410, and the like. A part of the effect device (game device) is exposed to the back side through the opening 411. Moreover, the recessed part 202e which was covered with the back upper side part of the main board case 200 by a part of the lower side part of the cover door 302 is opened to the back side, and the connector openings 236a to 236g are exposed.

  Further, as shown in FIGS. 15B and 16A, when the cover door 302 is in the intermediate position, the edge of the notch 325 in the inclined edge 306 of the cover door 302 is formed at the left end of the cover member 202. The left side of the regulated portion 281 is retracted to the back side. Specifically, when the main board case 200 is slid from the attachment position toward the left attachment / detachment position, the edge of the notch 325 in the inclined edge 306 does not contact the restricted part 281 with respect to the restricted part 281. Thus, the edge of the notch 325 on the inclined edge 306 is disposed so as to be separated from the back side by a predetermined gap L15. Note that the edge of the notch 325 is in a position where it can abut against the regulated portion 281.

  Further, the left-right gap L14 from the restricted portion 280 to the edge of the notch 325 is longer than the left-right width L11 of the groove 424 (L14> L11). By making the gap L14 longer than the left and right width dimension L11 in this way, the edge of the notch 325 in the inclined edge 306 becomes the restricted portion 280 before the main board case 200 reaches the attachment / detachment position from the attachment position. The sliding movement is not restricted by contacting (contacting) 281. That is, when the cover door 302 is in the intermediate position, the cover door 302 does not come in contact with the main board case 200 from the attachment position to the attachment / detachment position, and can be slid to the attachment / detachment position. The main board case 200 can be removed from the mounting portion 420.

  Specifically, as shown in FIG. 16B, when the main board case 200 is slid from the attachment position to the attachment / detachment position as shown in FIG. When the moving distance L16 longer than the left-right width dimension L11 is moved, the locked state by the locking pieces 230a to 230c is released. Since the moving distance L16 is shorter than the gap L14 from the end edge of the notch 325 to the restricted portion 280 at the mounting position (L16 <L14), the restricted portion 280 comes into contact with the edge of the notch 325 by the sliding movement. By this time, the locked state is released. Therefore, after the locked state is released, the main board case 200 is pulled out so that the right side of the main board case 200 is tilted to the back side, and the sliding movement is not restricted by contacting the cover door 302. It can be removed from the mounting portion 420.

  Further, when the main board case 200 is attached to the attachment portion 420 when the cover door 302 is in the closed position or the open position, the main board case 200 is placed at the attachment / detachment position due to the edges of the restriction pieces 322 and the notches 325 being in the way. Therefore, the main board case 200 cannot be attached to the attachment portion 420. Only when the cover door 302 is at the intermediate position, the main board case 200 can be disposed at the attachment / detachment position while avoiding the edges of the restricting piece 322 and the notch 325, so that the main board case 200 is attached to the attachment portion 420. Can be attached to. However, since it is necessary to dispose the main board case 200 from the lower side of the cover door 302 at the attachment / detachment position, the cover door 302 may be attached in a state of being removed from the base cover 410.

  In the present embodiment, the main board case 200 can be detached from the mounting portion 420 at an intermediate position where the cover door 302 is substantially orthogonal to the back plate 410e. Since the edge of 325 includes all positions where it does not come into contact with the regulated portions 280 and 281, a swing range (e.g., about 10 to 20) that actually tilts to the right and left by a predetermined angle with respect to a position substantially orthogonal to the back plate 410 e. Intermediate range).

  In this embodiment, as an example of the specific position where the main board case 200 can be detached from the attachment portion 420, an intermediate position within the swing range between the closed position and the open position is applied. If the open position includes a swing range of a predetermined angle, a part of the open position may be set as the specific position. Furthermore, the specific position may be set not only at one place but also at a plurality of places.

  As described above, in the pachinko gaming machine 1 as an embodiment of the present invention, as shown in FIG. 13, when the cover door 302 is in the closed position, the main board case 200 is removed from the attachment position. Since the right end surface of the bent piece 322b of the regulating piece 322 contacts (contacts) the regulated portion 280 during the sliding movement to the middle, the sliding movement is regulated and the main board case 200 cannot be moved to the attachment / detachment position. It cannot be removed from the mounting portion 420. As shown in FIG. 14, when the cover door 302 is in the open position, the edge of the notch 325 on the inclined edge 306 is in the middle of sliding the main board case 200 from the attachment position to the attachment / detachment position. Since the sliding movement is restricted by being brought into contact with (contacting) and cannot be moved to the attachment / detachment position, the main board case 200 cannot be removed from the attachment portion 420. As described above, when the main board case 200 is removed from the attachment portion 420, the cover door 302 cannot be removed by contact with the cover door 302 if it is in the closed position or the open position. 302 can be used to suppress an illegal act of removing the main board case 200 from the mounting portion 420 and replacing it with the main board case 200 containing an illegal circuit board.

  Such fraudulent activity may occur not only during the business hours of the amusement store but also outside the business hours. Therefore, if it takes time to perform fraud, it becomes more noticeable and it becomes easier to find fraud. In this embodiment, in order to remove or attach (detach) the main board case 200 from the attachment portion 420, it is necessary to work while maintaining the cover door 302 at the intermediate position or to remove it from the base cover 410. It takes time and effort. That is, when a third party removes the legitimate main board case 200 from the mounting portion 420 or replaces and attaches it to a board case containing an illegal board, the cover door 302 becomes an obstacle or the cover door. Since it takes time and effort to maintain and remove 302 at the intermediate position, it is possible to suppress such fraud.

  In the present embodiment, the gaming board 6 including the rendering unit 300 configured as described above is assembled to the front frame 101 constituting the pachinko gaming machine 1 (see FIG. 2) and removed from the front frame 101. Even in the closed state (see FIG. 4), as described above, the main board case 200 comes into contact with the cover door 302 at both the closed position and the open position of the cover door 302 so that it cannot be attached to and detached from the mounting portion 420. It has become. However, as shown in FIG. 2, when the game board 6 is assembled to the front frame 101, it contacts a member on the front frame 101 side such as a passage cover case 97a of the payout passage located on the left side of the rendering unit 300. For example, the opening / closing may be limited only within a swing range of about 90 degrees between the closed position and the intermediate position.

  Thus, when the intermediate position shown in FIGS. 15 and 16 is the open position, the main board case 200 does not come into contact with the cover door 302 during sliding movement at the open position (intermediate position). The substrate case 200 can be attached to and detached from the attachment portion 420. However, for example, even if the main board case 200 does not come into contact with the cover door 302 during sliding movement from the attachment position to the attachment / detachment position, the main board case 200 cannot be removed by contacting the frame side member such as the passage cover case 97a. If the game board 6 is not removed from the front frame 101, the main board case 200 cannot be removed from the attachment portion 420. In such a case, it takes time to remove the game board 6 from the front frame 101, and even if it is removed from the front frame 101, there is no restriction on the swing range of the cover door 302. 13 and the open position shown in FIG. 14, the main board case 200 contacts the cover door 302 and cannot be removed from the mounting portion 420, thereby suppressing fraud. can do.

  Further, the main board case 200 can be detached from the attachment portion 420 by sliding from the attachment position of the attachment portion 420 to the attachment / detachment position where the main substrate case 200 can be attached / detached to / from the attachment portion 420, and reaches the attachment / detachment position from the attachment position. Since the sliding movement is restricted by contacting (contacting) the cover door 302 by the time, it cannot be removed from the mounting portion 420. Specifically, as shown in FIG. 13, when the cover door 302 is in the closed position, the right end surface of the bent piece 322b of the regulating piece 322 is moved while the main board case 200 is slid from the attachment position to the attachment / detachment position. Since the sliding movement is restricted by contacting (contacting) the regulated portion 280 and cannot be moved to the attachment / detachment position, the main board case 200 cannot be removed from the attachment portion 420. As shown in FIG. 14, when the cover door 302 is in the open position, the edge of the notch 325 on the inclined edge 306 is in the middle of sliding the main board case 200 from the attachment position to the attachment / detachment position. Since the sliding movement is restricted by contacting (contacting) the sheet and cannot be moved to the attachment / detachment position, the main board case 200 cannot be removed from the attachment part 420. By doing in this way, the main board case 200 can be held at a position where it cannot be attached to and detached from the attachment portion 420 by contact with the cover door 302, that is, at a position other than the attachment / detachment position. Can be made more difficult to remove.

  Also, when the main board case 200 is in a position other than the attachment / detachment position, when the user tries to pull it out from the mounting portion 420 to the back side, the load is transmitted to the base cover 410 having a high strength as a casing of the effect unit 300, and the cover door Since it is not directly applied to 302, damage to the cover door 302 is prevented. That is, the main board case 200 is not restricted to move in the detaching direction at the attachment / detachment position at which the main board case 200 can be detached from the attachment part 420, but only the sliding movement in a state in which the main board case 200 cannot be detached from the attachment part 420. Therefore, it is possible to prevent the main board case 200 from being removed without significantly increasing the strength of the cover door 302.

  Further, the restricting piece 322 is formed in the vicinity of the swinging shaft portion 305 (for example, the restricting piece 322 is closer to the swinging shaft portion 305 (swinging center) than the center position in the left-right direction of the cover door 302. In addition, the swing shaft portion 305 is provided at a vertical position on the left side of the cover door 302, and the restricting piece 322 is a swing shaft below the center position in the left-right direction of the cover door 302. Therefore, even if a load is applied to the restricting piece 322 due to the sliding movement of the main board case 200, the restricting piece 322 in the cover door 302 is not easily deformed. can do.

  In addition, since the swing axis of the cover door 302 is oriented in a direction perpendicular to the sliding movement direction of the main board case 200, the cover door 302 can be loaded even if a load is applied to the restriction piece 322 due to the sliding movement of the main board case 200. Since it is difficult for the position to shift, the slide movement can be reliably regulated. Further, since the opening / closing movement direction of the cover door 302 is different from the sliding movement direction of the main board case 200, the cover door 302 is not opened / closed by the sliding movement of the main board case 200.

  Further, in this embodiment, only the recess 202e on the upper side of the main board case 200 is covered with the cover door 302, but only a part of the main board case 200 is covered in this way. It may be formed, or the whole may be covered.

  The cover door 302 is detachably provided on bearings 412a and 412b provided on a base cover 410, which is a predetermined base member, and the main board case 200 removes the cover door 302 from the base cover 410. Thus, the cover door 302 does not get in the way when an amusement store employee or the like inspects or replaces the main board case 200, so that the work can be easily performed. be able to.

  The main board case 200 can be removed from the mounting portion 420 when the cover door 302 is at an intermediate position that is a specific position other than the closed position and the open position. Since the substrate case 200 can be removed from the mounting portion 420, the main substrate case 200 can be easily inspected and replaced without removing the cover door 302.

  In the present embodiment, the main board case 200 is configured to be removable from the mounting portion 420 when the cover door 302 is in the intermediate position. However, as described above, the cover door 302 is removed from the base cover 410. By removing the main board case 200, the main board case 200 can be slid to the attachment / detachment position, so that it can be removed from the attachment portion 420 without being obstructed by the cover door 302.

  Further, in the present embodiment, the main board case 200 is configured to be removable from the attachment portion 420 when the cover door 302 is in the intermediate position as the specific position. It is not necessary to provide a specific position that can be removed from the attachment portion 420. In this case, when a game clerk attaches the main board case 200 to the attachment portion 420 or removes it for inspection or the like, the cover door 302 may be removed from the base cover 410.

  Further, in this embodiment, as an example of a gaming device, an effect movable device (not shown) for driving an effect movable object (not shown) provided to be able to advance on the display screen of the effect display device 9, Various presentation devices such as the display device 9, the production control board case 500, and the relay board (not shown) are illustrated, but any device provided in the pachinko gaming machine 1 includes all devices other than the production device.

  In this embodiment, the cover door 302 as an example of a cover member can cover various effect devices (game devices) constituting the effect unit 300 provided on the back surface of the board 400 in the game board 6. However, the present invention is not limited to the cover door 302 that can cover such an effect device, but a game device other than the effect device as described above, for example, a substrate case or a front surface for storing other substrates such as a power supply substrate and a payout substrate It may be a cover member capable of covering a gaming device provided in a place other than the game board 6 such as various devices provided in the frame 101. That is, the gaming device to be covered is not limited to the device provided on the game board 6.

  In this embodiment, the cover door 302, which is an example of a cover member, is configured by a plate-like member. However, if the game apparatus can be covered, the cover member is a member other than the plate-like member, for example, Further, it may be constituted by a rod-shaped member, a punching metal, or the like, or may be formed with a hole or the like that does not hinder the protection of the gaming apparatus.

  In the present embodiment, the opening 411 is configured to be closed at the closed position where the gaming apparatus is covered. However, the present invention is not limited to this, and the gaming apparatus is covered at the covering position. If possible, the gaming device may not be covered by closing an opening such as the opening 411 at the covering position. Moreover, it is not limited to what closes the whole opening in a closed position, At least one part of an opening should just be closed in a closed position.
