  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, a special winning opening (one of the winning areas) is opened a predetermined number of times (for example, 15 times), and a transition is made to a specific gaming state in which a hit ball is easy to win. This type of large winning opening includes a variable winning ball apparatus including an opening / closing plate that performs an operation that allows a game ball to be awarded or easily opened from a closed state where the game ball cannot be awarded or difficult when a predetermined condition is satisfied. 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.

  As an example of such a variable winning ball device, a first path and a second path through which the game medium that has flowed down the first path and the start point is located on the end point side of the first path can pass. And the game medium that has started at the opposite side of the end point of the first route across the second route and has flowed down the first route and did not enter the second route. A plate-like shape that can convert between a possible third path and a first state (first position) in which a game ball can enter the second path and a second state (second position) incapable of entering. In a prize opening unit provided with a moving member, the moving member is provided such that the moving member can be reciprocated linearly in a substantially horizontal direction between one end and the other end of a movable range of the reciprocating motion. For example, see Patent Document 1).

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 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.

  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 starting memory number by winning at the first starting winning port 13a and the starting memory number by winning at the second starting 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.

When the specific display result (big hit symbol) is derived and displayed, and when the specific display result (big hit symbol) is derived and displayed on the second special symbol indicator 8b, When the moving member 305 is controlled to be in an open state by the solenoid 21, the large winning opening 20a serving as a winning area is opened.

  A count switch 23a capable of detecting an entered game ball is provided in the special winning opening 20a. Based on the detection of the game ball by the count switch 23a, 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.

  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, for example, two lamps. When the game ball passes through the gate 32 and is detected by the gate switch 32a, variable display of the normal symbol display 10 is started. 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.

  In the vicinity of the special variable winning ball apparatus 20, winning holes 29a to 29c of the normal winning apparatus are provided, and the game balls that have won the left winning holes 29a to 29c are detected by the winning hole switch 30a, and then to the right winning hole 29d. The winning game ball is detected by the winning opening switch 30b. Each of the winning ports 29a to 29c 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 20a also constitute a winning area that accepts a game ball 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.

  A game ball launched from a ball striking device (not shown) by the player's operation enters the game area 7 and then descends the game area 7. The game area 7 is divided into a left area 7a on the left side and a right area 7b on the right side of the effect display device 9 disposed substantially at the center, and the game ball fired in the first operation mode is the left area 7a. For example, the game ball launched in the second operation mode in which the amount of rotation of the operation knob 5 is larger than that in the first operation mode flows down the right region 7b.

  In the present embodiment, the game balls launched into the left area 7a can win the first start prize opening 13a, the second start prize opening 13b, and the prize openings 29a to 29c, and the game balls launched into the right area 7b. Are arranged with obstacles such as obstacle nails and windmills (not shown) so that the second start winning opening 13b, the large winning opening 20a, and the winning opening 29d can be awarded.

  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 (effect 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 (effect 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 this embodiment, when the big hit symbol corresponding to “non-probability change” and “probability change A” is stopped and displayed in the special game in the special figure game, the first big win state (15 rounds) as the multi-round specific game state is displayed. (Big hit state). In the first big hit gaming state, the moving member 305 of the special variable winning ball apparatus 20 has a predetermined period (for example, 29.5 seconds) or a period until a predetermined number (for example, eight) of winning balls are generated. When the special winning opening 20a is opened, the special variable winning ball apparatus 20 is changed to the first state (open state) advantageous for the player. In this way, the moving member 305 that opened the grand prize opening 20a during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the special prize opening 20a, thereby making a special variable prize. The ball 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 that is the open cycle of the big winning opening 20a is 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, 15 out balls (prize balls) are obtained each time a game ball wins the big winning opening 20a. The 15 round round big hit state is also referred to as a first specific gaming state.

  When the big hit symbol corresponding to the “certain change B” as the confirmed special symbol in the special figure game is stopped and displayed, the state shifts to the second big hit state (7 round big hit state) as the multi-round specific gaming state. In the second big hit game state, the moving member 305 of the special variable winning ball device 20 has a predetermined period (for example, 29.5 seconds) or a period until a predetermined number (for example, eight) of winning balls are generated. When the special winning opening 20a is opened, the special variable winning ball apparatus 20 is changed to the first state (open state) advantageous for the player. In this way, the moving member 305 that opened the grand prize opening 20a during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the special prize opening 20a, thereby making a special variable prize. The ball device 20 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the 7 round big hit state, the number of executions of the round which is the open cycle of the big winning opening 20a becomes the second round number (for example, “7”).

  When the big hit symbol corresponding to “probability change C” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the third big hit state (high speed two round big hit state) as the multi-round specific gaming state. In the third big hit state, the moving member 305 of the special variable winning ball apparatus 20 has a second period (for example, 0.5 seconds) shorter than the first period in the first big hit state, or a predetermined number (for example, three) of winning balls. By making the special winning opening 20a open during the period until the occurrence of a round, a 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 moving member 305 that opened the grand prize opening 20a during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the special prize opening 20a, thereby making a special variable prize. The ball device 20 is changed to a third state (closed state) disadvantageous to the player, and one round is completed. In the third big hit state, the number of executions of the round which is the opening cycle of the big winning opening 20a is the fourth round number (for example, “2”).

  In such a third big hit state, 15 game balls (prize balls) are obtained if a game ball wins the big winning opening 20a, but the opening period of the big winning opening 20a is the second period (0.5 seconds). ) And very short. For this reason, the third big hit state is a big hit gaming state in which a pitch (prize ball) cannot be obtained substantially. The third big hit state is also called a third specific game state. Further, the third big hit state may be one in which the number of executions of the same round as the first big hit state or the second big hit state is small. That is, in the third big hit state, the period (opening condition) for changing the big winning opening 20a to the open state in each round is a second period shorter than the first period in the first big hit state, and the number of round executions May be at least one of the second round numbers smaller than the first round number in the first big hit state.

  In addition, after the first jackpot state is ended based on the fact that the jackpot symbol corresponding to “non-probable change” is stopped and displayed as a confirmed special symbol in the special figure game, it is compared with the normal state as one of the special gaming states. The time is controlled to be in a time-short state in which time-shortening control (short-time control) is performed in which the variable symbol display time (special-figure variation time) is shortened in the special game. 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. If the time-saving state ends when either of the predetermined number of times (e.g., 70 times) of the special figure game is executed and the variable display result is “big hit” is satisfied first, Good. Thus, like the big hit symbol special symbol corresponding to “non-probable change”, the big hit symbol controlled to the short-time state after the first big hit state based on being stopped and displayed as the confirmed special symbol in the special symbol game is This is called a non-probable big hit symbol (also referred to as “normal big hit symbol”). Further, the fact that the non-probable variable big hit symbol among the big hit symbols is stopped and displayed and the variable display result becomes “big hit” is called “non-probable big hit” (also referred to as “normal big hit”).

  The first big hit state, the second big hit state, and the third big hit state are ended based on the fact that the big hit symbol corresponding to “probability change A”, “probability change B”, and “probability change C” is stopped and displayed as the fixed special symbol in the special figure game. Later, as one of the special game states different from the short-time state, for example, the probability variation state (probability variation control) in which the probability variation control (probability variation control) is continuously performed together with the short-time control in which the special figure variation time is shortened compared to the normal state High probability state). In this probability change state, the variable display result of each special figure game and production symbol is improved so that the variable display result becomes “big hit” and the probability of being further controlled to the big hit gaming state is higher than in the normal state or 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.

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

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. In the probability variation state and time reduction state, it may also be any one of these controls are carried out, may be a plurality of control is performed is canceller I union. 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 addition, the probability variation state includes not only the time variation control and the high release control are performed together with the probability variation control but also the one in which only the probability variation control is performed and the time reduction control and the high release control are not performed (latency probability variation). It may be. Further, for example, after the end of the first big hit state based on the fact that the variable display result in the special figure game is “probable big hit”, the first positive change state (high-precision control in which the time-shortening control and the high opening control are performed together with the positive change control. When the number of executions of the special figure game reaches a predetermined number of times (for example, 70 times) without the special figure display result becoming “big hit”, the probability variation control is continued. Although it is performed, the control may be performed in a second certain variation state (also referred to as a highly accurate low base state) that is not performed after the time-shortening control or the high opening control is finished.

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

In the “left”, “middle”, and “right” 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 any special figure game among the special figure games using the second special figure on the display 8b, the variable display (variation display) of the effect symbols is started. Then, during the period from the start of variable display of the production symbol to the end of variable display due to the stop display of the finalized design symbol in each of the “left”, “middle”, and “right” production symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state, performance symbol that is not also yet the suspend display when the temporary stop displayed performance symbol in the display area of the effect display device 9 constitutes a part of the allowed I jackpot unions ( "reach varying design" also referred to as a) display state change is continued for or, to vary all or part of the performance symbol is synchronized while forming all or part of the cause jackpot union It is a display state. Specifically, "left", "middle", so I jackpot union has the predetermined (effect such as pattern display area, for example, "left" and "right") performance symbol display part in the area of the "right" The remaining effect symbol display area (for example, the “medium” effect symbol display area) that has not yet been temporarily stopped when the effect symbols (for example, the effect symbol indicating the alphanumeric character “7”) are temporarily stopped and displayed. display state in, etc.) performance symbol is changing, or, "left", "medium", the whole performance symbols in whole or in part in the performance symbol display area of the "right" is not I jackpot union or part The display state is changing in synchronization with the configuration.

  Further, in this embodiment, for example, during the variation display of the production symbol, the announcement effect that predicts that the big hit or reach state has been established, the reach production, the big hit effect, the probability change that suggests the possibility that the probability variation control is being performed. Various effects such as suggestion effects can be executed.

The power supply board 90 is supplied with the game control board 31 and each electrical component control board (the effect control board 80 and the payout control board 37) in the pachinko gaming machine 1 and each electrical component (power is supplied) provided in the pachinko gaming machine 1. A power switch as a power supply permission means for executing or shutting off power supply to a component that operates by the operation), and a clear switch for clearing the RAM 55 of the game control microcomputer 156 of the game control board 31 are provided. ing. 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, lamp or LED (light emitting diode) provided in the gaming machine according to a command signal (control signal) as a command from the game control means or the like. ) Etc., the 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 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. 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 signals, prize ball signals 1, gaming machine error status signals) is provided. Note 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.

  The game balls stored in the storage tank 38 pass through the guide rails, and reach the ball payout device 97 covered with the payout case 97a via the curve rod. 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. In this state, the rotation of the payout motor in the ball payout device is stopped, the operation of the ball payout device is stopped, and the driving of the ball hitting device is also stopped.

  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, 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 23a, 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 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, 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) 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 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 120 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.

  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).

  As shown in FIGS. 4 to 8, the winning unit 300 constituting the special variable winning ball apparatus 20 includes a base member 301 attached to the game board surface 6 a of the game board 6 and a cover member 302 attached to the front surface of the base member 301. And a drive unit 303 assembled to the back surface of the base member 301.

  In particular, as shown in FIG. 5, on the front surface of the base member 301, a first guiding path 310 that guides the gate 32 and the game ball passing therearound toward the left side is inclined downward toward the left side. Is formed. From the downstream end of the first guide path 310, a second guide path 311 for guiding the game ball flowing down the first guide path 310 extends obliquely downward to the left, and the second On the opposite side of the first guide path 310 across the guide path 311, a third guide path 312 for guiding a game ball that has not entered the second guide path 311 extends toward the left side. The upstream end of the second guide path 311 that is a branching portion with the third guide path 312 is opened to form a big prize opening 20a. That is, the third guide path 312 extends from the left end portion of the special winning opening 20a toward the left side.

  The special winning opening 20a can be opened and closed by a moving member 305 provided so as to be reciprocally movable. The game ball that has flowed down the first guide path 310 enters the second guide path 311 from the big prize port 20a when the big prize port 20a is opened by the moving member 305, and is provided in the second guide path 311. Is detected by the count switch 23a. When the big prize opening 20a is closed by the moving member 305, the moving member 305 passes through the big prize opening 20a and is guided to the third guide path 312.

  The base member 301 is composed of a plate member attached to the front surface of the game board surface 6a. A gate 32 through which a game ball can pass is projected on the upper front portion, and a gate switch 32a is assembled from the back side of the gate 32. ing. In addition, a path forming part 320 that forms the first guide path 310 protrudes below the gate 32.

  The upper surface constituting the bottom surface of the path forming unit 320 has a front and rear width dimension that allows a game ball to flow down, and a first inclined surface 320a that is inclined diagonally to the left and downward from a lower right end position of the gate 32, and a first inclined surface 320a. A second inclined surface 320b inclined obliquely downward and leftward from the inclined lower side end of the first inclined surface 320a and having a larger inclination angle than the first inclined surface 320a, and obliquely leftwardly inclined from the inclined lower side end of the second inclined surface 320b. A third inclined surface 320c that is inclined toward the second inclined surface 320b and has a larger inclination angle than the second inclined surface 320b, and a fourth inclined surface 320d that is inclined obliquely downward and to the right from the upper end of the inclined side of the first inclined surface 320a. Are formed, and the first to third inclined surfaces 320a to 320c constitute the flow lower surface of the first guide path 310.

  In other words, the game ball that has passed through the gate 32 is guided toward the big prize opening 20 a by the first guide path 310. In addition, on the left side of the gate 32 above the first guide path 310, a ball guide portion 321 protrudes with a gap through which the game ball can pass from the first guide path 310. The ball guiding portion 321 is disposed slightly on the upper right side of the special winning opening 20a, and a game ball falling downward on the left side of the gate 32 directly falls on the moving member 305, causing the moving member 305 to be damaged. This prevents the movement operation from being hindered, or prevents the count switch 23a from being damaged by being dropped directly onto the second guide path 311 when the special winning opening 20a is opened, and also passes through the gate 32 to be on the first inclined surface 320a. It functions as a guide member that guides the game ball that has fallen and jumped to the first guide path 310 to stably flow down.

  On the left side of the path forming portion 320, a substantially arc-shaped insertion groove 322 through which the moving member 305 is inserted is centered on a rotation shaft described later, from the approximately 10 o'clock position to the approximately 4 o'clock position when viewed from the front. It is formed over a range of about 180 degrees. In addition, the inner edge of the insertion groove 322 has an arc shape with the rotation axis as the center, while the outer edge is formed so as to gradually move away from the inner edge toward the right side from the left side. That is, the insertion groove 322 is formed so as to gradually widen from the left side to the right side.

  On the left side of the insertion groove 322, a path forming part 323 that constitutes a part of the third guide path 312 is attached. In addition, an opening 324 for guiding the game ball flowing down the second guide path 311 to the back side of the base member 301 is formed at the lower position.

  In addition, a wiring insertion port 325 is formed on the right side of the insertion groove 322. Although not specifically shown, a decorative light emitting diode or the like for illuminating the cover member 302 from the inside is provided in the cover member 302 made of a synthetic resin material having translucency. The wiring from the light emitting diode can be extended to the back side of the base member 301 through the wiring insertion port 325.

  The cover member 302 is formed in a box shape with an open rear surface, and covers the lower area of the first guide path 310 and the third guide path 312 on the front surface of the base member 301, that is, the second guide path 311 from the front side. To be attached. An upper plate 326 that contacts the lower surface of the path forming portion 320 is formed on the right side of the upper side of the cover member 302, and a path plate 327 that forms a part of the third guide path 312 is formed on the left side of the upper side. Yes. The upper plate 326 and the route plate 327 are arranged apart from each other so as to form the big prize opening 20a and allow the moving member 305 to be inserted.

  On the back surface of the cover member 302, a passage wall 328 that forms the second guide path 311 is formed from the space between the upper plate 326 and the path plate 327 to the opening 324 diagonally to the lower left. That is, the second guide path 311 is formed by the base member 301 on the back surface and the passage wall 328 of the cover member 302 on the bottom surface and the front surface. A notch 328a for fixing the count switch 23a is formed below the passage wall 328. In addition, a guide wall 329 is formed on the right side of the passage wall 328 so as to follow the right peripheral edge of the insertion groove 322.

  The first guiding path 310 and the third guiding path 312 have path forming portions 320 and 323, a path plate 327 on the bottom surface, a plate-shaped portion of the base member 301 on the back surface, and a transparent window 102a (on the front surface of the glass door frame 102). 11) and is configured to be able to guide the game ball. Further, the second guide path 311 includes a plate-like portion of the cover member 302 on the bottom surface and the front surface and the base member 301 on the back surface, and is configured to be able to guide the game ball.

  As shown in FIGS. 7 to 11, the drive unit 303 includes a drive base 340 attached to the back surface of the base member 301, a base cover 341 that covers the back surface of the drive base 340, and a swing shaft on the front side of the drive base 340. Mainly from a moving member 305 attached to be rotatable about 342, a solenoid 21 fixed to the back side of the drive base 340, and a link member 343 for transmitting the driving force of the solenoid 21 to the moving member 305. It is configured. Further, a guide member 345 for guiding the moving member 305 and a relay substrate 344 for connecting the solenoid 21 and the count switch 23a to the main substrate 31 are provided on the front surface of the drive base 340.

  The solenoid 21 is fixed to the back surface of the drive base 340 so that a plunger 21a provided so as to extend and contract with respect to the main body protrudes downward. The plunger 21a is urged in the protruding direction by a spring 21b mounted on the outer periphery of the plunger 21a. The plunger 21a expands with respect to the main body in a non-excited state, and contracts toward the main body when excited. . A connecting member 346 having a horizontally long connecting hole 346a is attached to the tip of the plunger 21a.

  The link member 343 is made of a strip-shaped synthetic resin material, and includes a linear portion 343a and a curved portion 343b that is connected to the linear portion 343a and has a substantially inverted U shape when viewed from the front. Yes. The right end portion of the linear portion 343a is pivotally supported on the right side of the back surface of the drive base 340 by a swing shaft 350 facing in the front-rear direction, and is provided so as to be swingable about the swing shaft 350.

  A connecting shaft 351 (see FIG. 9) projects from the connecting portion between the linear portion 343a and the curved portion 343b on the back surface of the link member 343, and is inserted into the connecting hole 346a. Further, a horizontally long connecting hole 352 is formed at the left end of the curved portion 343b. The link member 343 configured in this way is disposed on the front side of the plunger 21a.

  The moving member 305 includes a plate member 361 having a substantially fan shape in front view with a swing shaft 342 fixed to the lower end, an opening / closing plate 360 provided along the upper side of the plate member 361, and the plate member 361 from the swing shaft 342. The connecting member 362 extends in different directions, and a connecting shaft 363 protrudes from the lower back surface of the connecting member 362.

  The moving member 305 is disposed on the front side of the drive base 340, and the swing shaft 342 inserted from the back side through the insertion hole 364 formed in the drive base 340 is not rotatable relative to the lower end of the plate member 361. By being fixed to the drive base 340, the drive base 340 is pivotally supported via a swing shaft 342. Further, in a state where the shaft is supported, the connecting shaft 363 is inserted into a connecting hole 352 disposed on the back side through an arc-shaped elongated hole 365 formed in the drive base 340 and connected to the link member 343.

  The open / close plate 360 is formed of a synthetic resin material having a band plate shape, and is provided so as to form a substantially inverted L-shaped longitudinal section with respect to the plate member 361 as shown in FIG. 20a has a size that can be opened and closed. In particular, as shown in FIG. 9, the upper surface 360 a is formed in a substantially circular arc shape centering on the swing shaft 342 when viewed from the front. That is, the upper surface 360a of the opening / closing plate 360 is configured by a curved surface that bulges to the guidance path side (first and third guidance path sides) of the game ball.

  Further, the opening / closing plate 360 is provided so that the distance from the swing shaft 342 to the downstream end portion P1 is longer than the distance r2 from the swing shaft 342 to the upstream end portion P2 with respect to the plate member 361. (R1 <r2). That is, when the moving member 305 rotates around the swing shaft 342, the movement trajectories of the downstream end P1 and the upstream end P2 of the opening / closing plate 360 are different from each other.

  The moving member 305 configured in this way is in a closed position (see FIG. 9) where the open / close plate 360 is disposed so as to cover the big prize opening 20a, and retracts from the big prize opening 20a into the cover member 302 into the big prize. It is provided so as to be movable between an open position (see FIG. 10) for opening the mouth 20a.

  When the conditions for opening the special winning opening 20a are not satisfied, as shown in FIG. 9, the solenoid 21 is in the OFF state, and the plunger 21a is biased downward by the biasing force of the spring 21b. At this time, the link member 343 connected to the plunger 21a via the connecting shaft 351 is held at a lower limit position that is inclined slightly downward toward the left side. In this state, the curved portion 343b is detoured so as to surround the swing shaft 342 so as to avoid contact with the swing shaft 342.

  When the conditions for opening the special winning opening 20a are satisfied, as shown in FIG. 10, the solenoid 21 is turned on, and the plunger 21a is pulled upward against the urging force of the spring 21b. As a result, the link member 343 connected to the plunger 21a via the connecting shaft 351 is biased upward in the vicinity of the swing shaft 350, so that the front view clockwise with the swing shaft 350 as the center. Swing. In response to this, the moving member 305 connected to the link member 343 via the connecting shaft 363 swings clockwise around the swing shaft 342 in the front view.

  Then, when the moving member 305 rotates about the swing shaft 342, the opening / closing plate 360 moves to the right side from the closed position covering the special winning opening 20a and is held in the open position, and the special winning opening 20a is in the open state. It becomes. The link member 343 is held at an upper limit position inclined slightly upward toward the left side.

  Thus, the drive unit 303 has the link member 343 as a transmission mechanism that converts the power in the vertical direction of the plunger 21a of the solenoid 21 into the rotational power of the moving member 305 and transmits it.

  In this embodiment, the rocking shaft 350 of the link member 343 is provided at a position away from the rocking shaft 342 of the moving member 305, and the moving member 305 is based on the rocking shaft 342. The solenoid 21 is connected to the link member 343 on the swing shaft 350 side with respect to the swing shaft 342 while being connected to the link member 343 on the side opposite to the 350.

  Since the curved portion 343 b is formed in the link member 343, the link member 343 becomes the swing shaft 342 even when the swing shaft 342 is disposed within the swing range of the link member 343. The link member 343 can be swung without causing interference. By forming the curved portion 343b in this way, the link member 343 is shifted in the axial direction of the swing shaft 342 (the front side or the rear side of the swing shaft 342) so as not to interfere with the swing shaft 342. Since there is no need, the front-rear width dimension of the drive unit 303 can be made as narrow as possible.

  Further, since the weight is increased by forming the curved portion 343b as compared with the case where the link member 343 is formed only by the linear portion, the plunger 21a is moved by the biasing force of the spring 21b as shown in FIG. When the link member 343 is extended, the downward movement of the plunger 21a is assisted by the weight of the link member 343. Therefore, a load for rotating the moving member 305 toward the closed position of the special winning opening 20a is reduced.

  In the drive unit 303 configured as described above, the opening / closing plate 360 of the moving member 305 disposed on the front surface side of the drive base 340 is inserted through the insertion groove 322 and protrudes forward from the plate-like portion of the base member 301. Thus, it is assembled to the back surface of the base member 301 so that the upper portion of the large winning opening 20a in the guide path can be closed.

  Next, the effect | action at the time of turning operation | movement of the moving member 305 is demonstrated based on FIGS.

  As shown in FIG. 12, the first guide path 310 extends so as to incline downward toward the left side. As shown in FIG. 5, the second guide path 311 extends from the downstream end KP2 of the first guide path 310 so as to incline downward toward the left side. The third guide path 312 is inclined downward from the upstream end KP1 (the downstream end of the large winning opening 20a forming the upper end opening of the second guide path 311) toward the left side of the second guide path 311. It is so extended. The upstream end KP1 of the third guide path 312 is provided on the downstream side of the large winning opening 20a from the downstream end KP2 of the first guide path 310, and at a position away downward. That is, the special winning opening 20a has a horizontally long rectangular shape in plan view, and is formed so as to be inclined downward from the upstream side (right side in the figure) toward the downstream side (left side in the figure).

  When the opening / closing plate 360 of the moving member 305 is in the closed position, the downstream end P1 of the upper surface 360a of the opening / closing plate 360 approaches (or abuts) the upstream end KP1 of the third guide path 312 and the upper surface 360a. The upstream side end portion P2 of the first guide path 310 is close to the downstream side end portion KP2. Specifically, the downstream end P1 is located on a virtual straight path K connecting the upstream end KP1 and the downstream end KP2, and the upstream end P2 is second than the straight path K. Located on the guide path 311 side (downward).

  The trajectory (movement trajectory) of the downstream end P1 on the upper surface 360a of the opening / closing plate 360 is an arc trajectory M that is a part of a circular trajectory centered on the swing shaft 342. A part is provided on the guide path side (first and third guide path sides) of the game ball. That is, the downstream end P1 at the closed position of the opening / closing plate 360 is located on the straight path K, and the downstream end P1 (hereinafter referred to as P1 ″) at the open position is located below the straight path K. The downstream end P1 (hereinafter referred to as P1 ′) between the closed position and the open position and in the vicinity of the closed position is located closer to the guide path than the straight path K. Furthermore, in a closed position, it is provided so that a part (downstream part) of the upper surface 360a of the opening-and-closing plate 360 may bulge to the path | route side.

  That is, in the moving member 305, the downstream end P1 on the upper surface 360a of the opening / closing plate 360 passes on the circular arc track M along the first guide path 310 and the third guide path 312 from the open position to the closed position. The arc trajectory M is a trajectory heading in a direction away from the flow-down direction F of the game ball as the moving member 305 approaches the closed position.

  Specifically, as shown in FIG. 12, when the moving member 305 is in the open position, an arrow X3 indicating a direction in which the downstream end P1 ″ of the upper surface 360a of the opening / closing plate 360 faces (tangential direction in the circular orbit M) The vector indicating the direction of the force, the direction of the velocity vector, and the direction of the acceleration vector are the guidance paths of the upper game ball, that is, the guidance paths (the closed position) that connect the first guidance path 310 and the third guidance path 312. It is directed to a guiding path consisting of a guiding path of a game ball that can pass through the upper surface 360a of the moving member 305. That is, the circular arc trajectory M is a trajectory heading in a direction approaching the guidance path of the game ball.

  On the other hand, when the moving member 305 is at a predetermined position in the vicinity of the closed position, the arrow X2 indicating the direction of the downstream end P1 ′ on the upper surface 360a of the opening / closing plate 360 (the direction of the tangential force in the circular orbit M is indicated). The direction of the vector, the velocity vector, and the acceleration vector shown is the guidance path of the upper game ball, that is, the guidance path that connects the first guidance path 310 and the third guidance path 312 (the upper surface of the moving member 305 in the closed position). It is directed to the opposite side of the guide route consisting of the guide route of the game ball that can pass through 360a.

  When the moving member 305 is in the closed position, an arrow X1 indicating a direction in which the downstream end P1 of the upper surface 360a of the opening / closing plate 360 is directed (a vector indicating a direction of a tangential force in the circular orbit M, a velocity vector, The direction of the acceleration vector is a guidance path of the upper game ball, that is, a guidance path that connects the first guidance path 310 and the third guidance path 312 (game that can pass through the upper surface 360a of the moving member 305 in the closed position). It faces the opposite side of the guide route consisting of the guide route of the sphere.

  That is, when the moving member 305 moves from the open position toward the closed position, the arrow X3 faces the guidance path side of the game ball until the downstream end P1 reaches the top of the circular arc track M. The member 305 moves in a direction approaching the guide path of the game ball, and after the downstream end P1 passes through the top of the circular arc track M, the arrows X2 and X1 face the opposite side of the guide path of the game ball. The moving member 305 moves in a direction away from the game ball guiding path. That is, the circular arc trajectory M is a trajectory that goes away from the game ball guide path (the game ball flow-down direction F) as the moving member 305 approaches the closed position.

  Note that, in the closed position, the tangents at arbitrary positions of the portion that bulges further to the path side than the straight path K on the upper surface 360a of the opening / closing plate 360 are provided so as to be inclined downward toward the downstream side. The game ball falling on the upper surface 360a is guided toward the downstream side by natural flow. As described above, the opening / closing plate 360 is provided so that the downstream end portion P1 reciprocally swings in the range between the downstream end portions P1 and P1 ″ of the circular arc track M centering on the swing shaft 342. .

  As shown in FIG. 13A, the downstream end surface 360b of the opening / closing plate 360 and the upstream end surface 323b of the path forming portion 323 are vertical surfaces extending in the vertical direction, and the moving member 305 is closed. It is inclined at a predetermined angle θ with respect to an arrow X1 indicating a direction in which the downstream end P1 is directed when moving toward the position.

  In the present embodiment, the downstream end surface 360b and the upstream end surface 323b are inclined at a predetermined angle θ with respect to the arcuate track M, but the predetermined angle θ can be variously changed and becomes as small as possible. Is preferred.

  Further, as shown in FIG. 13B, as the moving member 305 approaches the closed position, for example, the downstream end portion in the downward arrows X1 ″, X1 ′, X1 indicating the direction toward the downstream end portion P1. The angle of inclination with respect to a perpendicular (not shown) going downward from P1 changes so as to gradually decrease.

  Therefore, when the game ball Z is sandwiched between the downstream end surface 360b of the opening / closing plate 360 and the upstream end surface 323b of the path forming portion 323 when the moving member 305 approaches the closed position, the vertical path forming portion 323 is inserted. The downstream end surface 360b of the opening / closing plate 360 is inclined upward with respect to the upstream end surface 323b, and the direction toward the downstream end P1 (the direction indicated by the arrows X1 ″, X1 ′, X1) is gradually increased. By changing so that the inclination angle with respect to the perpendicular (not shown) gradually decreases, the inclination angle with respect to the upstream end face 323b becomes larger. That is, since the direction in which the game ball Z is pushed into the upstream end surface 323b is shifted downward, it becomes easier to enter the lower part of the spherical game ball Z, so that the game ball Z is pushed in the direction orthogonal to the upstream end surface 323b. Compared to, game balls are less likely to get caught.

  In this way, the game ball Z easily enters the lower part of the game ball Z and floats upward, so that the game ball Z is less likely to be sandwiched between the downstream end surface 360b of the opening / closing plate 360 and the upstream end surface 323b of the path forming portion 323. , The occurrence of clogging can be suppressed.

  Next, based on FIG. 14 to FIG. 17, the flow-down situation of game balls according to the movement of the opening / closing plate 360 will be described.

  As shown in FIG. 14 (A), when the open / close plate 360 is in the open position, most of the game balls Z flowing down the first guide path 310 are in the second guide path 311 via the big prize opening 20a. And is detected by the count switch 23a.

  As shown in FIG. 14B, until the opening / closing plate 360 rotates by a predetermined angle from the open position and the downstream end P1 reaches the approximate vertex position of the circular arc track M, the downstream end P1 is moved upward. Yes, since the tangent line passing through the downstream end P1 intersects the inclined straight path K, the game ball falling on the upper surface 360a from the first guide path 310 jumps upward, and Since it is pushed by the opening / closing plate 360 that moves toward the downstream side, it is easy to be guided to the third guiding path 312 over the special winning opening 20a.

  Further, the game ball that has dropped on the upper surface 360a until the opening / closing plate 360 rotates by a predetermined angle from the open position and the downstream end P1 reaches the substantially vertex position of the circular arc track M is shown in FIG. In addition, since the tangent line passing through the downstream end P1 is inclined opposite to the inclined linear path K, it is easy to jump upward. As shown in FIG. 15 (B), the open / close plate 360 continues to move while jumping. Therefore, until the jumping game ball moves to the downstream side and falls, FIG. 15 (C ) Is approaching the closed position of the big prize opening 20a, it is difficult to fall into the big prize opening 20a.

  Further, as shown in FIGS. 14C and 14D, after the opening / closing plate 360 further rotates by a predetermined angle from the open position and the downstream end P1 passes through the approximate vertex position of the circular arc track M, the downstream side The end portion P1 is descending and the tangent line passing through the downstream end portion P1 crosses the inclined straight path K in the opposite direction, so that the game ball dropped from the first guide path 310 onto the upper surface 360a. Is pushed by the opening / closing plate 360 that moves upward and downstream, and therefore easily jumps over the special winning opening 20a and is guided to the third guide path 312.

  In particular, since the upstream end P2 has a longer distance from the swing shaft 342 than the downstream end P1, the opening / closing plate 360 rotates, so that the upstream end P2 side of the opening / closing plate 360 with respect to the game ball. Since the action of being pushed from behind by this works, the game ball can easily jump over.

  As described above, the moving member 305 is provided so as to move from the open position to the closed position on the circular orbit M passing through the guide path side with respect to the straight path K, and thus from the big prize opening 20a. In addition, the game ball collides with the game ball at the upper position and guides the game ball toward the third guide path 312, thereby making it easy for the game ball to jump over the big prize opening 20 a. That is, immediately before reaching the closed position, it is difficult for the game ball to enter between the downstream end surface 360b and the upstream end surface 323b, so that the game ball is not easily sandwiched between the downstream end surface 360b and the upstream end surface 323b. can do.

  Further, as shown in FIG. 16 (A), after the downstream end P1 of the opening / closing plate 360 passes through the substantially vertex position of the circular arc track M, the downstream end P1 and the upstream end KP1 are between the downstream end P1 and the upstream end KP1. Even when the game ball is about to enter, the direction toward the downstream end P1 (for example, the direction indicated by arrows X1, X2, etc. in FIG. 12) changes downward, so that the game ball is diagonally lower right. Since the action of pushing the position to the downstream side works, as shown in FIG. 16B, it is possible to push the game ball to the third guide path 312 side while preventing it from falling vertically downward.

  As shown in FIG. 17, when the opening / closing plate 360 is maintained in the closed position, the game ball that has dropped from the first guide path 310 moves so as to roll on the upper surface 360a. Further, when moving from the closed position to the open position, since the upper surface 360a is formed in a curved shape, the entire upper surface 360a moves along the substantially circular arc trajectory M. Compared with the case where the upper surface 360a is a flat surface (see FIG. 18), the inclination direction of the upper surface 360a does not change greatly according to the movement of the opening / closing plate 360, so that the game ball can flow smoothly.

  As described above, when the opening / closing plate 360 moves from the open position to the closed position, the game ball that has dropped from the first guide path 310 onto the upper surface 360a is moved by the opening / closing plate 360 on the path side above the winning prize opening 20a. It becomes easy to be guided to the third guiding path 311 side, and it is difficult for the game ball to flow down on the upper surface 360a and enter the space between the downstream end P1 and the path forming part 323 constituting the downstream edge of the big prize opening 20a. Therefore, it is sandwiched between the downstream side end portion P1 and the path forming portion 323, and it becomes difficult for the ball to be caught.

  Further, in the present embodiment, the upper surface 360a of the opening / closing plate 360 is configured by a curved surface that bulges toward the guide path side, but like the opening / closing plate 1360 of the moving member 1305 as a modification shown in FIG. The upper surface 1360a may be a flat surface.

  Thus, even if the upper surface 1360a is in the opening / closing plate 1360 configured as a flat surface, the downstream end P1 is closer to the guide path side than the straight path K, as shown in FIGS. If it is provided so as to pass on the circular arc track, the opening / closing plate 1360 rotates by a predetermined angle from the open position, and the downstream end P1 is at the substantially vertex position of the circular arc track M, as shown in FIG. Until it reaches the downstream end P1, the upper end 1360a crosses the inclined linear path K, so that the game ball dropped from the first guide path 310 onto the upper surface 1360a is Since it jumps upward and is pushed by the opening / closing plate 1360 moving toward the downstream side, it is easy to be guided to the third guiding path 312 by jumping over the big prize opening 20a.

  Further, as shown in FIGS. 18B and 18C, after the opening / closing plate 1360 further rotates by a predetermined angle from the open position and the downstream end P1 passes through the substantially vertex position of the circular arc track M, the downstream side Since the end P1 is a downward movement and the upper surface 1360a intersects the inclined linear path K in the opposite direction, the game ball dropped on the upper surface 1360a from the first guide path 310 is upward, and Since it is pushed by the opening / closing plate 1360 moving toward the downstream side, it is easy to be guided to the third guiding path 312 over the special winning opening 20a.

  As shown in FIG. 18D, when the open / close plate 1360 is in the closed position, the upper surface 1360a is substantially parallel to the straight path K that tilts to the lower left, so that the game ball is guided to the third guide path 312. To do.

  As described above, in the pachinko gaming machine 1 according to the embodiment of the present invention, the opening and closing plate 360 of the moving member 305 is moved from the open position that is the first position toward the closed position that is the second position. The first and third guide paths are moved in a circular arc path toward the flow direction F of the game ball, and the circular arc path moves in the flow direction F of the game ball as the downstream end P1 of the opening / closing plate 360 approaches the closed position. Since the opening / closing plate 360 moves away from the guide path along the circular arc track M as it approaches the closed position, the opening / closing plate 360 is linearly moved from the open position to the closed position along the guide path. Compared with the case where it moves, it can reduce that a game ball is pinched | interposed between the path | route formation part 323 and the opening-and-closing plate 360 which comprise the downstream edge part of the special winning opening 20a, and raise | generates a ball | bowl.

  Moreover, in the said Example, since the upper surface 360a in the opening-and-closing plate 360 is formed in the curved surface which curves so that it may bulge to the guidance path | route side, the opening-and-closing plate 360 is compared with the case where the upper surface 360a is a flat surface. Since the inclination direction of the upper surface 360a does not change greatly according to the movement of the game ball, the game ball can flow smoothly.

  In the embodiment, the upper surface 360a of the opening / closing plate 360 has a larger distance r2 from the swing shaft 342 to the upstream end P2 than to a distance r1 from the swing shaft 342 to the downstream end P1. However, the distance r1 and the distance r2 may be set to the same length.

  In the embodiment, the opening / closing plate 360 is provided such that a predetermined position such as the downstream end P1 moves along the circular arc track M that is a part of the circular track centering on the swing shaft 342. However, it is not necessarily limited to one that moves on an arc orbit that forms a part of a circular orbit, and is provided so as to be movable on an arc orbit formed in a substantially arc shape that is not a perfect circle, such as an elliptic orbit. It may be.

  Moreover, in the said Example, although the downstream edge part P1 was provided so that it might be located in the big winning opening 20a side rather than the upstream edge surface 323b of the path | route formation part 323 in a closed position, a downstream edge part in a closed position It may be provided such that P1 stops on the upper surface of the path forming portion 323, that is, an extension line of the circular arc track M passes through the upper surface of the path forming portion 323.

  In the embodiment, the first to third guide paths 310 to 312 which are guide paths for the game balls are provided so as to be inclined downward from the right side to the left side of the game board surface 6a. You may provide so that it may incline below toward. Alternatively, the guidance path of the game ball is provided in the direction along the game board surface 6a, but may be extended toward the direction intersecting the game board surface 6a, for example, the back side of the game board surface 6a.

  Further, in the above embodiment, the moving member 305 is configured to move in the downward direction of the game ball from the open position toward the closed position, so that it collides with the game ball immediately before reaching the closed position. However, the impact was less than when moving the game ball from the open position to the closed position in the direction opposite to the flow-down direction, but along the guide path of the game ball from the open position to the closed position. What is necessary is just to be comprised so that it may move.

  FIG. 19 shows a moving member 2305 as a modification of the present invention. As described above, the moving member 2305 as the present modification is configured to move in the direction opposite to the flow-down direction F of the game ball from the open position to the closed position.

  Even in such a configuration, when the moving member 305 moves from the open position toward the closed position, the arrow X10 ″ remains until the downstream end P10 ″ reaches the top of the circular arc track M. Since it faces the guide path side of the game ball, the moving member 305 moves in a direction approaching the guide path of the game ball, and after the downstream end P10 ′ passes the top of the circular arc track M, the arrows X10 ′ and X10 are Since it faces away from the guide path of the game ball, the moving member 305 moves in a direction away from the guide path of the game ball. In other words, even when the game ball is configured to move in the direction opposite to the flow-down direction F of the game ball from the open position to the closed position, the arc trajectory M guides the game ball as the moving member 305 approaches the closed position. Since the trajectory goes away from the path (flowing direction F of the game ball), the same action / effect as the moving member 305 described in the above embodiment is achieved.

  In the embodiment, the drive unit 303 includes the solenoid 21, the link member 343 that connects the solenoid 21 and the opening / closing plate 360, and the swing shaft 342 that pivotally supports the opening / closing plate 360. The link member 343 is provided so as to be movable in a direction (vertical direction) intersecting the swinging shaft 342 facing in the front-rear direction, and has a curved portion 343b for avoiding the swinging shaft 342, and is open or closed. Since the curved portion 343b is arranged around the swinging shaft 342 at the position, even when the link member 343 moves in a direction intersecting the swinging shaft 342, the link member 343 is moved in the axial direction of the swinging shaft 342. Since the interference with the swing shaft 342 can be avoided without shifting in the front-rear direction, the moving member 305 can be moved in a space-saving manner.

  Moreover, in the said Example, when the moving member 305 moves from an open position to a closed position, the arrow X3 (tangent in the circular orbit M) which shows the direction which the downstream end part P1 '' in the upper surface 360a of the opening-and-closing plate 360 goes to The direction of the force of the direction, the direction of the velocity vector, the direction of the acceleration vector) is directed in the direction approaching the guidance route, and the arrows X2 and X1 are directed in the direction away from the guidance route. When the moving member 305 moves from the open position to the closed position, arrows X1 to X3 (indicating the direction of the tangential force in the circular orbit M indicate the direction of the downstream end P1 on the upper surface 360a of the open / close plate 360). A circular orbit in which the vector, the velocity vector, and the direction of the acceleration vector) all face the direction away from the guidance path (the flow direction F of the game ball) may be used.

  In the above-described embodiment, the drive unit 303 as drive means includes the solenoid 21, the link member 343 that connects the solenoid 21 and the opening / closing plate 360, and the swing shaft that pivotally supports the opening / closing plate 360. 342. However, as long as the moving member 305 can be moved on the circular arc path M between the closed position and the open position, the components can be variously changed, and a motor is used as a drive source. May be provided so as to be movable through a transmission mechanism such as the motor and a gear member.

  In the above-described embodiment, the example in which the present invention is applied to the special variable winning ball apparatus 20 has been described. However, the variable winning ball apparatus 15 and other winning holes are not limited to the winning apparatus opened in the big hit gaming state. The present invention can also be applied to a variable winning device.

  Further, in the above embodiment, the moving member 305 as the moving member of the special variable winning ball apparatus 20 can open and close the large winning opening 20a that opens upward. For example, a winning formed on the game board surface 6a. The mouth can be opened and closed.

  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.
