Consequently, the game ball guided into the big winning passage 305 hardly drops.

Description

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

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

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

JP 2009-45117 A

  In the gaming machine described in Patent Document 1, the movable plate is provided on the bottom surface of the passage so as to be capable of linear reciprocation, and retreats with the ball receiving surface facing upward. In the retreat movement, the game ball placed on the ball receiving surface hardly generates an external force in the retreat direction, so the game ball placed on the ball reception surface often spills out during the retreat movement, It was difficult to increase the winning rate.

  Therefore, in order to prevent the game ball placed on the ball receiving surface from spilling out during the retraction movement of the movable plate, it is conceivable to move the ball receiving surface forward and backward while tilting the ball receiving surface toward the aisle side. There was a problem that the winning rate when entering the market would increase too much.

  The present invention has been made paying attention to such problems, and provides a gaming machine equipped with a variable winning device that can vary the rate of entry of game balls into the approach passage according to the position of the movable member. The purpose is to do.

The first special symbol display 8a and the second special symbol display 8b each variably display a number (or a two-digit symbol) from 0 to 99 using, for example, two 7-segment LEDs. It may be configured.

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

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

  The effect display device 9 is for decoration (effect) during the variable display time of the first special symbol on the first special symbol display 8a and during the variable display time of the second special symbol on the second special symbol display 8b. Display design (also referred to as a decorative design) as a design.

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.

Therefore, in this embodiment, the game ball won in the first grand prize opening 20a is guided to the back of the game board 6, first detected by the first count switch 23a, and then detected by the third winning confirmation switch 23b. The

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

  Further, a second special variable winning ball apparatus 20B is provided obliquely above and to the right of the variable winning ball apparatus 15. The second special variable winning ball apparatus 20B includes a movable plate 20d. When a specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a, and on the second special symbol display 8b, the specific display result ( When the movable plate 20d is controlled to be opened by the solenoid 21b in a specific gaming state (big winning gaming state) that occurs when the big winning symbol) is derived and displayed, the second big winning port 20c serving as a winning area is opened. become.

  Two switches (a second count switch 24a and a fourth winning confirmation switch 24b) capable of detecting a game ball won in the second major winning opening 20c are provided in the second major winning opening 20c. In this embodiment, a second count switch 24a and a fourth winning confirmation switch 24b are arranged in the second big prize opening 20c (in this example, the second count switch 24a is arranged on the upper side, The winning confirmation switch 24b is arranged on the lower side). Therefore, in this embodiment, the game ball won in the second grand prize opening 20c is guided to the back of the game board 6, first detected by the second count switch 24a, and then detected by the fourth winning confirmation switch 24b. The

  Based on the detection of the game ball by the second count switch 24a, a predetermined number (for example, 15) of game balls are paid out as prize balls. Thus, when the game ball passes (enters) through the second large winning opening 20c that has been opened in the second special variable winning ball apparatus 20B, for example, the first starting winning opening 13a, the second starting winning opening 13b, etc. More prize balls are paid out than when a game ball passes (enters) through the prize opening. Therefore, when the second special prize winning device 20B is in the open state in the second special variable winning ball apparatus 20B, the first state advantageous to the player is obtained. On the other hand, in the second special variable winning ball apparatus 20B, if the second big prize opening 20c is in a closed state, the game ball cannot pass through (enter) the second big prize opening 20c to obtain a prize ball. The second state is disadvantageous for the player.

  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 storage 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 the first special variable winning ball device 20A at the time of a big hit, for example. There are two display sections (segments) that indicate the number of times of opening (number of big hit rounds), and two display sections (segments) that indicate the gaming state, but these display sections are separate from the normal symbol hold storage display section. You may comprise with a display. Further, the normal symbol display 10 may be configured by a segment LED or the like that can variably display a plurality of types of identification information (for example, “◯” and “x”) called normal symbols.

  The winning holes 29a to 29d of the normal winning device are provided around the first special variable winning ball device 20A, and the game balls that have won the winning ports 29a to 29c are detected by the winning port switch 30a and won to the winning port 29d. The game ball is detected by the winning opening switch 30b. Each of the winning holes 29a to 29d constitutes a winning area provided in the game board 6 as an area for accepting game balls and allowing winning. The first start winning opening 13a, the second starting winning opening 13b, the first big winning opening 20a, and the second big winning opening 20c also constitute a winning area that accepts game balls and allows winning.

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

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

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

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

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

  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.

  In this embodiment, when the big win symbol corresponding to the “first big hit” or “second big hit” is stopped and displayed in the special figure game, the big hit state (15 rounds) as the multi-round specific gaming state is displayed. (Big hit state). In the big hit gaming state (15 round big hit state), the big winning opening door 20b of the first special variable winning ball apparatus 20A has a predetermined period (for example, 29.5 seconds) or a predetermined number (for example, eight) of the first period. A round in which the first special variable winning ball apparatus 20A is changed to a first state (open state) advantageous to the player by opening the first large winning opening 20a in a period until a winning ball is generated. Executed. In this way, the grand prize opening door 20b that opened the first 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 first big prize opening 20a. Thus, the first special variable winning ball apparatus 20A is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In such a 15 round big hit state, every time a game ball wins a big winning opening, 15 balls (prize balls) are obtained.

  In the 15 round big hit state, the number of executions of the round that is the opening cycle of the first big winning opening 20a becomes a predetermined number of rounds (for example, “14”), and the second big winning opening 20c is opened in the remaining one round. It is supposed to be a round. For example, the first grand prize opening 20a is opened in the first to eighth and 10-15th rounds excluding a predetermined round (the ninth round in this embodiment), and the second big prize opening 20c in the ninth round which is the predetermined round. Becomes an open state.

  Specifically, when the big hit symbol corresponding to “second big hit” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the first big hit state. In the ninth round in the first big hit state, the movable plate 20d of the second special variable winning ball device 20B has a first period (for example, 0.5 seconds) shorter than the second period in the second big hit state or a predetermined number (for example, By repeating the control to open the second large winning opening 20c 15 times during the period until three (3) winning balls are generated, the second special variable winning ball device 20B is in a first state advantageous to the player. A round to change to (open state) is executed. Thus, the movable plate 20d that opened the second grand prize opening 20c during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the second big prize opening 20c. Then, the second special variable winning ball apparatus 20B is changed to the second state (closed state) which is disadvantageous for the player, and one round is completed.

  In such a ninth round in the first big hit state, 15 game balls (prize balls) can be obtained if a game ball wins the second big prize opening 20c, but the opening period of the second big prize opening 20c is long. The first period (0.5 seconds) is very short. Therefore, the ninth round in the first big hit state is a big hit gaming state in which a ball (prize ball) cannot be obtained substantially. The first big hit state is also referred to as a first specific gaming state.

  On the other hand, when the big hit symbol corresponding to “second big hit” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the second big hit state. In the ninth round in the second big hit state, the movable plate 20d of the second special variable winning ball apparatus 20B has a second period (for example, 29.5 seconds) longer than the first period in the first big hit state or a predetermined number (for example, The second special variable winning ball apparatus 20B is in a first state (open) advantageous for the player by performing control to open the second large winning opening 20c during a period until eight winning balls are generated. A round to change to (state) is executed. Thus, the movable plate 20d that opened the second grand prize opening 20c during the execution of the round receives the game ball falling on the surface of the game board 6, and then closes the second big prize opening 20c. Then, the second special variable winning ball apparatus 20B is changed to the second state (closed state) which is disadvantageous for the player, and one round is completed.

  In such a ninth round in the second big hit state, 15 game balls (prize balls) are obtained if a game ball wins the second big prize opening 20c, and the opening period of the second big prize opening 20c is Since it is the second period (29.5 seconds), the ninth round in the second jackpot state is substantially a jackpot gaming state in which a ball (prize ball) is obtained. The second big hit state is also referred to as a second specific gaming state.

  Further, the second big hit state may be one in which the number of execution rounds of the second big winning opening 20c is larger than that in the first big hit state. That is, in the second big hit state, the period in which the second big prize opening 20c is changed to the open state in each round is a second period longer than the first period in the first big win state, and the number of round executions is the first. It may be at least one of the second round numbers greater than the first round number in the big hit state.

  In addition, after the first big hit state and the second big hit state are ended based on the fact that the big hit symbol corresponding to “first big hit” or “second big hit” is stopped and displayed as a confirmed special symbol in the special figure game, As one of the gaming states, the time is controlled to be in a time-short state in which time-shortening control (time-shortening control) is performed in which the variable symbol variable display time (special-figure variation time) is shortened compared to the normal state. 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. The time-short state may be terminated when one of the conditions is established first, among a predetermined number of times (for example, 30 times) of the special game and the variable display result being “big hit”. .

  Then, in the first big hit state and the second big hit state, when a game ball wins more than a predetermined number (for example, one ball) in the second big winning opening 20c, the first big hit state and the second big hit state are finished. After that, as one of the special game states different from the short-time state, for example, the probability variation state (high probability state) in which the probability variation control (probability variation control) is performed together with the short-time control in which the special figure variation time is shortened compared to the normal state. ) Is controlled. In this probabilistic state, the variable display result of each special figure game and decorative design is improved so that the probability that the variable display result will be “big hit” and further controlled to the big hit gaming state will be higher than in the normal state and the short-time state. To do. Such a probability change state continues until the next variable display result is a “big hit”, regardless of the number of executions of the special game.

  That is, in this embodiment, in both the first big hit state and the second big hit state, there is a possibility that a game ball wins the second big winning opening 20c and the state shifts to the probable change state after the big hit state ends. There is a possibility that the game ball does not win the big winning opening 20c and does not shift to the probability change state after the big hit state ends, but in the second big hit state, the gaming ball wins the second big winning opening 20c during the big hit state. The possibility of being higher than the first big hit state.

  Here, as shown in FIG. 1 and FIG. 19, the game area 7 of the pachinko gaming machine 1 is divided into left and right with the effect display device 9 as the center, and the game ball that is struck on the left side of the effect display device 9 is the left region. The game balls that have flowed down 7a and hit the right side flow down the right region 7b and join at the lower part of the game region 7. Most of the game balls driven into the right region 7b will be described later by guide surfaces formed on the guide passage members 650a to 650c capable of guiding the game balls flowing down in the left-right direction, obstacle nails (not shown), and the like. The second special variable winning ball apparatus 20B is configured to pass in front of the second large winning opening 20c. Although not particularly illustrated, obstacle nails and the like are arranged so that the game ball does not win the first start winning opening 13a when right-handed.

  The game balls that have not won the second grand prize opening 20c are further guided toward the variable winning ball apparatus 15, and are awarded in the open state. Furthermore, the game balls that have not won the variable winning ball device 15 are further guided toward the first special variable winning ball device 20A, and win if they are in the open state.

  Therefore, if a right hit is made during a big hit game and a game ball is thrown into the right region 7b, the game passes through the second special variable winning ball device 20B and the variable winning ball device 15; otherwise, the first special variable winning ball device 20A. To be guided to. In the ninth round, most of the right-handed game balls pass in front of the second special variable winning ball device 20B, so that the game balls have a chance to win the second special variable winning ball device 20B.

  In this embodiment, the probability that the first big hit result and the second big hit result are displayed as display results in the special figure game is about 1/250, for example, and the first special figure game has a ratio of about 50% at the big hit. The first big hit result is displayed at a rate of about 50%, and the second big hit result is displayed at a rate of about 20% in the second special figure game, the first big hit result at a rate of about 20% and the second big hit at a rate of about 80%. The result will be displayed. In other words, the second special figure game is more advantageous to the player than the first special figure game because it has a higher probability of being in the second big hit state. Since the time-shortening control is not performed, the second start winning opening 13b is rarely won and the flow to the first starting winning opening 13a is restricted and cannot be controlled. It is more advantageous for the player than driving in the right region 7b to drive in the first start winning opening 13a.

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

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

The 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 winning balls are defined as data indicating the progress state of the game. In this embodiment, it is assumed that the entire RAM 55 is backed up.

  A reset signal from the power supply board is input to the reset terminal of the game control microcomputer 156. A reset circuit for generating a reset signal supplied to the game control microcomputer 156 and the like is mounted on the power supply board. When the reset signal becomes high level, the game control microcomputer 156 and the like are in an operable state, and when the reset signal becomes low level, the game control microcomputer 156 and the like become inactive. Therefore, an allowable signal that allows the operation of the game control microcomputer 156 or the like is output during a period in which the reset signal is at a high level, and a game control microcomputer in which the reset signal is at a low level. An operation stop signal for stopping the operation of 156 or the like is output. Note that the reset circuit may be mounted on each electric component control board (a board on which a microcomputer for controlling the electric parts is mounted).

  Further, a power-off signal indicating that the power supply voltage from the power supply board has dropped below a predetermined value is input to the input port of the game control microcomputer 156. That is, the power supply board monitors the voltage value of a predetermined voltage (for example, DC30V or DC5V) used in the gaming machine, and when the voltage value decreases to a predetermined value (the power supply voltage is reduced). A power supply monitoring circuit that outputs a power-off signal indicating that). Instead of mounting the power monitoring circuit on the power supply board, it may be mounted on a board that is backed up by a backup power supply (for example, the main board 31). Further, a clear signal indicating that the clear switch for instructing to clear the contents of the RAM is operated is input to the input port of the game control microcomputer 156.

  Further, the gate switch 32a, the first start opening switch 14a, the first winning confirmation switch 14b, the second starting opening switch 15a, the second winning confirmation switch 15b, the first count switch 23a, the third winning confirmation switch 23b, and the second count. An input driver circuit 58 that supplies detection signals from the switch 24a, the fourth winning confirmation switch 24b, and the winning opening switches 30a and 30b to the basic circuit is also mounted on the main board 31, and the solenoid 16 that opens and closes the variable winning ball device 15, A solenoid 21a that opens and closes the first special variable winning ball apparatus 20A, a solenoid 21b that opens and closes the second special variable winning ball apparatus 20B, and an output circuit 59 that is driven in accordance with a command from the basic circuit are also mounted on the main board 31. System reset for resetting the game control microcomputer 156 An information output circuit 64 that outputs an information output signal such as a jackpot information indicating the occurrence of a jackpot gaming state or a jackpot information to the external device such as a hall computer via the terminal board 91 is also 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, an effect control CPU (not shown) operates according to a program stored in a built-in or external ROM (not shown), and receives from the main board 31 inputted via the relay board 77. An effect control command is received via the input driver and the input port in response to the embedded signal (effect control INT signal). Further, the effect control CPU (not shown) causes the VDP (video display processor) to perform display control of the effect display device 9 based on the effect control command.

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

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

  As a signal direction regulating means, the signal inputted from the main board 31 is allowed to pass through the relay board 77 only in the direction toward the effect control board 80 (the signal is not passed in the direction from the effect control board 80 to the relay board 77). A unidirectional circuit (not shown) is mounted. For example, a diode or a transistor is used as the unidirectional circuit. Furthermore, since the production control command and the production control INT signal are output from the main board 31 via the I / O port unit which is a unidirectional circuit, the signal going from the relay board 77 to the inside of the main board 31 is restricted. . That is, the signal from the relay board 77 does not enter the inside of the main board 31 (the game control microcomputer 156 side).

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

  In the lamp driver board 35, a signal for driving the LED is input to the LED driver via an input driver (not shown). The LED driver supplies a drive signal to each LED provided on the frame side such as the top frame LED 28a, the left frame LED 28b, and the right frame LED 28c. Further, a drive signal is supplied to the decoration LED 25a provided on the game board side. When a light emitter other than the LED is provided, a drive circuit (driver) for driving the light emitter is mounted on the lamp driver substrate 35.

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

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

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

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

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

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

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

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

  In this embodiment, it is confirmed whether or not the data in the backup RAM area is stored using both the backup flag and the check data, but only one of them may be used. That is, either the backup flag or the check data may be used as an opportunity for executing the game state restoration process.

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

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

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

  Further, the CPU 56 executes a random number circuit setting process for initially setting the random number circuit 60 (step S14). For example, the CPU 56 performs setting according to the random number circuit setting program so as to cause the random number circuit 60 to update the random R value.

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

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

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

  When the timer interrupt occurs, the CPU 56 executes the timer interrupt process of steps S20 to S34 shown in FIG. In the timer interrupt process, first, a power-off detection process for detecting whether or not a power-off signal is output (whether or not an on-state is turned on) is executed (step S20). The power-off signal is output, for example, when a power supply monitoring circuit mounted on the power supply board detects a decrease in the voltage of the power supplied to the gaming machine. In the power-off detection process, when detecting that the power-off signal has been output, the CPU 56 executes a power supply stop process for saving necessary data in the backup RAM area. Next, detection signals from the gate switch 32a, the first start port switch 14a, the second start port switch 15a, the first count switch 23a, the second count switch 24a, and the winning port switches 30a and 30b are input via the input driver circuit 58. These are input, and their state is determined (switch processing: step S21).

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

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

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

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

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

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

  Further, the CPU 56 executes prize ball processing for setting the number of prize balls based on detection signals from the first start port switch 14a, the second start port switch 15a, the first count switch 23a, and the second count switch 24a ( Step S30). Specifically, the payout control board 37 is activated in response to a winning detection based on any one of the first start port switch 14a, the second start port switch 15a, the first count switch 23a, and the second count switch 24a being turned on. A payout control command (award ball number signal) indicating the number of prize balls is output to a mounted payout control microcomputer. The payout control microcomputer drives the ball payout device 97 in accordance with a payout control command indicating the number of winning balls.

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

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

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

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

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

  6 and 7 are flowcharts showing an example of a special symbol process (step S26) program executed by the game control microcomputer 156 (specifically, the CPU 56) mounted on the main board 31. FIG. As described above, in the special symbol process, a process for controlling the first special symbol display 8a or the second special symbol display 8b, the first big prize opening 20a, and the second big prize opening 20c is executed. In the special symbol process, if the first start opening switch 14a for detecting that the game ball has won the first start winning opening 13 is turned on, that is, the start to the first starting winning opening 13 is performed. If a winning has occurred, a first start port switch passage process is executed (steps S311 and S312). If the second start port switch 15a for detecting that the game ball has won the second start winning port 14 is turned on, that is, the start winning to the second start winning port 14 has occurred. Then, the second start port switch passage process is executed (steps S313, S314). Then, any one of steps S300 to S310 is performed. If the first start port switch 14a or the second start port switch 15a is not turned on, any one of steps S300 to S310 is performed according to the internal state.

  The processes in steps S300 to S312 are as follows.

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

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

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

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

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

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

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

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

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

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

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

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

  When the round start waiting time elapses in step S396 (step S396; Yes), the winning number counter is cleared and the winning number count value, which is the stored value, is initialized to “0” (step S397). Also, based on the set big hit flag, it is confirmed whether the big hit type is the first big hit or the second big hit. And if it is 1st-8th and 10-15th round, the maximum opening time (for example, 29500 ms) of the 1st big winning opening 20a will be set. In the case of the ninth round, the maximum opening time (for example, 500 ms) of the second big winning opening 20c is set in the case of the first big win, and the maximum opening time (for example, 500 ms) in the case of the second big win ( For example, 29500 ms) is set (step S398). At this time, for example, the solenoids 21a and 21b are driven to set the first big prize opening 20a or the second big prize opening 20c to the open state (step S399). Furthermore, a setting for transmitting a round start command to the effect control board 80 is performed (step S400). Then, after updating the value of the special figure process flag to “6” which is a value corresponding to the process for opening the big prize opening (step S401), the process for opening the big prize opening is ended.

  FIG. 9 is a flowchart showing an example of the process executed in step S306 of FIG. In the special winning opening opening process shown in FIG. 9, the CPU 56 first determines whether or not a winning ball detection waiting time is set (step S410), and when the winning ball detection waiting time is not set. (Step S410; No), it is determined whether or not the maximum winning opening maximum opening time has elapsed (Step S411). At this time, if the maximum winning opening maximum opening time has not elapsed (step S411; No), it is determined whether or not the first count switch 23a or the second count switch 24a is on (step S412). If the count switch 23a or the second count switch 24a is on (step S412; Yes), the winning number count value is updated to be incremented by 1 (step S413), and then the winning ball number command is transmitted to the payout control board 37. (Step S414), the process proceeds to Step S415. If the first count switch 23a or the second count switch 24a is not on (step S412; No), the process proceeds to step S415 as it is.

  When the second count switch 24a is on, it is set if the probability change flag for shifting to probability change control after the big hit gaming state is not set.

  In step S415, it is determined whether or not the winning number count value has reached a predetermined maximum winning determination value (for example, “8”) (step S415). If the predetermined maximum winning determination value has not been reached, a big win is determined. End the mouth open process.

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

  Here, the award ball detection waiting time is the time it takes for a game ball won immediately before closing the grand prize door 20b and the movable plate 20d to pass through the first count switch 23a and the second count switch 24a. The length of a winning ball guiding passage (not shown) from the first big winning opening 20a to the first count switch 23a, and the length of a winning ball guiding passage (not shown) from the second big winning port 20c to the second count switch 24a. It is set accordingly. That is, the game balls detected by the first count switch 23a and the second count switch 24a after closing the grand prize opening door 20b and the movable plate 20d based on the fact that the above-mentioned round end condition is satisfied, Thus, the game ball is detected as an over-winning game ball and is not detected as a game ball won in the next round.

  If the prize ball detection waiting time is set in step S410 (step S410; Yes), it is determined whether or not the prize ball detection waiting time has elapsed (step S420), and the prize ball detection waiting time has elapsed. If not (step S420; No), it is determined whether the detection signals from the first count switch 23a and the second count switch 24a are on (step S422), the first count switch 23a, If the detection signal from the 2-count switch 24a is on (step S422; Yes), a prize ball number command is transmitted to the payout control board 37 (step S423), and the process of opening the special winning opening is completed. If the second count switch 24a is on in step S422; Yes, if the probability change flag for shifting to probability change control after the end of the big hit gaming state is not set, it is set.

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

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

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

  Next, the second special variable winning ball apparatus 20B will be described with reference to FIGS.

The storage portion 306 is wider in the left-right width dimension than the first passage 305a. In addition, an opening 310 having a size capable of slightly projecting the upper part is formed in the front portion of the upper wall of the first passage 305a, but the upper part of the first passage 305a is allowed to slightly protrude. This is possible (see FIG. 17A).

  An opening 307 is formed in the rear wall of the bent portion 305c, and a decoration LED 304a is disposed at a rear position of the opening 307. Light irradiated forward from the decoration LED 304a is transmitted through the opening 307. By entering into the big prize passage 305, the game balls that have entered the big prize passage 305 are illuminated and decorated from behind.

  A second count switch 24a is disposed immediately below the bent portion 305c in the second passage 305b so as to be able to detect a game ball passing through the second passage 305b.

  In addition, a solenoid 21b is disposed at the upper rear portion of the big winning passage 305 with the plunger 308 facing forward. A connecting member 309 to the transmission member 302 is attached to the distal end of the plunger 308, and an engaging portion 309a having a downward U-shape is formed on the connecting member 309.

  At a position corresponding to the rear portion of the opening 310 on the outer surface of the side wall 300c of the passage member 300a, a turning shaft 311 that faces the left-right direction for rotatably supporting the transmission member 302 is provided. A connecting groove 312 formed in an arc shape with the rotation shaft 311 as the center is formed at a position above the rotation shaft 311.

  In addition, a guide groove 313L for moving and guiding the movable plate 20d in the front-rear direction and changing the posture is extended in the front-rear direction at a location corresponding to the housing portion 306. As shown in FIG. 14C, the guide groove 313L includes a first guide part 313a extending in the moving direction (front-rear direction) of the movable plate 20d, and a rear side of the first guide part 313a. A second guide part 313b provided to be inclined with respect to the first guide part 313a, and a third guide part 313c formed substantially parallel to the first guide part 313a on the rear side of the second guide part 313b. It is configured.

  Specifically, the first guide portion 313a is a linear guide groove that extends from the position near the front end of the side wall 300c so as to be inclined slightly downward toward the rear. The second guide portion 313b is a guide groove that is continuously provided from the rear end of the first guide portion 313a, has a larger inclination angle than the first guide portion 313a, and is formed at a position corresponding to the bent portion 305c. The third guide part 313c is a linear guide groove provided continuously from the rear end of the second guide part 313b and extending substantially parallel to the first guide part 313a, and is shorter than the first guide part 313a. It is a size.

  On the other hand, the passage member 300b has the shape of the side wall 300c and the plate portion 300d are formed in substantially the same manner as the passage member 300a, and a guide groove 313R having the same shape is formed at a position corresponding to the guide groove 313L. The rotating shaft 311 and the connecting groove 312 are not provided.

  The transmission member 302 is composed of a rod-shaped arm member, and has a shaft hole 320 through which the rotation shaft 311 is inserted at a substantially central position in the longitudinal direction. The transmission member 302 is pivotally supported around the rotation shaft 311. The A connecting shaft 321 facing in the left-right direction is projected inward at the upper end, and a long hole 322 is formed in the longitudinal direction at the lower end.

  The connecting shaft 321 is inserted through the connecting groove 312 and protrudes to the inner side of the side wall 300c in a state where the connecting shaft 321 is inserted through the rotation shaft 311 and supported by the shaft 3201, and is engaged with the engaging portion 309a of the connecting member 309. The Therefore, when the plunger 308 moves back and forth according to the excitation and release of the solenoid 21b, the connecting shaft 321 engaged with the engaging portion 309a moves back and forth in the connecting groove 312. It rotates back and forth around 311.

  The cover member 301 includes a left cover 301a attached to the outside of the left passage member 300a with a predetermined gap, a right cover 301b attached to the outside of the right passage member 300b with a predetermined gap, and the passage member 300a. And an upper cover 301c attached to the upper portion of the head.

  A mounting piece 331 is bent outward at the front end sides of the left cover 301a and the right cover 301b, and the second special variable winning ball apparatus 20B is attached to the back surface of the game board 6 via the mounting piece 331. The special winning opening 20c can be attached so as to face the front side through an opening formed in the game board 6.

  In addition, the transmission member 302 can be rotatably accommodated in a space formed between the left cover 301a and the side wall 300c of the passage member 300a. The rotation shaft 311 has a length that protrudes from the shaft hole 320 in a state where the transmission member 302 is inserted, and when the left cover 301a is attached, the rotation shaft 311 in the left cover 301a. Is pivotally fitted to and supported by a bearing 330 formed at a position corresponding to (see FIG. 16).

  As shown in FIG. 14, the movable plate 20d is a plate that can be moved back and forth in a lower portion of a big winning passage 305 that is an entry passage through which a game ball can enter in the game area 7 (right area 7b in this embodiment). The advancing position (see FIG. 14 (a)) that advances from the big winning path 305 to the game area 7 side, and the retreating position (FIG. 14) that retreats from the advanced position into the big winning path 305. (See (b)), and can be reciprocated in the front-rear direction.

  The second special variable winning ball apparatus 20B is in an open state (first state) in which the game ball is easy to win when the movable plate 20d is located at the advance position, and a prize is obtained when the movable plate 20d is located at the retreat position. It changes to the closed state (2nd state) which is not or is difficult to win.

  As shown in FIG. 13, the movable plate 20d includes a ball receiving portion 340 having a ball receiving surface 340a for receiving a game ball on the upper surface, and a fork extending from the left and right sides of the ball receiving portion 340 toward the rear side. And a guided portion 341 having a shape.

  The ball receiving portion 340 has a lateral width L1 shorter than the diameter 2R of the game ball, and a flat ball receiving surface 340a in the front / rear / right / left direction is formed on the upper surface, and falls from above. It is formed so that a game ball can be received from below. The front end surface of the ball receiving portion 340 is inclined by a pair of left and right inclined surfaces 340b and 340c which are inclined rearward from the central position in the left-right width direction toward the left and right sides and inclined rearward in the thickness downward direction. It is configured.

  As a result, even if a game ball is present between the movable window 20d and the see-through window 102a that allows the game area 7 formed in the glass door frame 102 to be seen through when the movable plate 20d has advanced to the advance position, Since the inclined surfaces 340b and 340c are inclined, the game balls are released to the left and right or below, so that the game balls are sandwiched between the see-through window 102a and the inclined surfaces 340b and 340c, and the solenoid 21b is loaded. Is prevented from being applied.

  The guided portion 341 includes a pair of left and right rod-shaped portions 341a and 341b extending rearward from the left and right rear end portions of the ball receiving portion 340, and between these rod-shaped portions 341a and 341b, A notch 342 having a left-right width dimension L2 longer than the diameter 2R and opened to the rear side is formed (L1 <2R <L2).

  A pair of front and rear guide shafts 343a to 343d that can be inserted into the guide groove 313L are projected outward from the front and rear positions on the outer surfaces of the rod-shaped portions 341a and 341b. Each of the guide shafts 343a to 343d has a columnar shape, and a washer portion 344 that is wider than the upper and lower widths of the guide grooves 313L and 313R is formed at each base portion, thereby preventing rattling in the left-right direction. .

  Of these guide shafts 343a to 343d, the left front guide shaft 343a protrudes from the guide groove 313L and is slidably inserted into the elongated hole 322 of the transmission member 302. That is, the movable plate 20d is connected to the solenoid 21b via the transmission member 302. Therefore, the movable plate 20d is moved between the advanced position and the retracted position by the plunger 308 moving back and forth in response to the excitation and release of the solenoid 21b and the transmission member 302 rotating back and forth about the rotation shaft 311. Move back and forth with.

  The guide shafts 343a to 343d are inserted into the left and right guide grooves 313L and 313R, respectively, and the four points on the front and rear and left and right sides of the guided portion 341 are supported by the guide grooves 313L and 313R, so To be maintained.

  Specifically, as shown in FIG. 14A, when the movable plate 20d is in the advanced position, all the guide shafts 343a to 343d are guided to the first guide portion 313a. In this state, the movable plate 20d can receive a game ball flowing down the right region 7b by projecting almost the entire area of the ball receiving surface 340a from the second big prize opening 20c to the front right region 7b. In addition, the ball receiving surface 340a is slightly tilted toward the second grand prize opening 20c (inclined upward toward the tip) and can receive the game ball received to the second big prize opening 20c. Become.

  When the movable plate 20d is in the retracted position, the front guide shafts 343a and 343c are guided by the first guide portion 313a, and the rear guide shafts 343b and 343d are positioned below the first guide portion 313a. 3 is guided to the guide 313c. In this state, the movable plate 20d receives the game ball flowing down the right region 7b by retracting the entire ball receiving surface 340a inside the second big prize opening 20c, that is, in the big prize passage 305. A second posture in which the ball receiving surface 340a is tilted to the side of the big prize passage 305 from the first posture and the game ball that has entered from the second big prize opening 20c cannot enter the big prize passage 305 is difficult. It becomes.

  That is, when the movable plate 20d is in the advanced position, the vertical width L3 of the second big prize opening 20c is longer than the diameter 2R of the game ball, but when the movable plate 20d is in the retracted position, the movable plate 20d is By tilting to the second posture, the tip of the ball receiving surface 340a faces upward, and the vertical width dimension L4 of the second big winning opening 20c becomes shorter than the diameter 2R of the game ball. Therefore, even if the second big prize opening 20c is not completely closed at the retracted position, the entry of the game ball from the second big prize opening 20c is restricted, so that it is possible to prevent the game ball from being illegally won. .

  In the retracted position, the rear guide shafts 343b and 343d are guided by the third guide portion 313c located below the first guide portion 313a, so that the guide shafts 343b and 343d are the third guide portion. Since the rotation of the movable plate 20d centering on the front guide shafts 343a and 343c is restricted by contacting the upper edge of 313c, the front end of the ball receiving portion 340 is forcibly pushed down and the front end of the second big prize opening 20c Since it is difficult to spread the game ball, it is possible to prevent the game ball from being illegally won.

  At the advance position where the game ball flowing down the right region 7b can be received, the protruding length L5 from the second big prize opening 20c to the tip of the ball receiving surface 340a is longer than the radius R of the game ball. (L5> R). In addition, in the advance position where it is difficult to receive the game ball flowing down the right region 7b, the protruding length L5 from the second big prize opening 20c to the tip of the ball receiving surface 340a is shorter than the radius R of the game ball. (L5 <R).

  Further, during the retraction movement from the advance position toward the retreat position side, the front guide shafts 343a and 343c are guided by the first guide portion 313a, and the rear guide shafts 343b and 343d are inserted into the second guide portion 313b. When applied, the movable plate 20d is in a state in which it is difficult to receive a game ball flowing down the right region 7b by retracting an area of about 2/3 or more of the ball receiving surface 340a into the big winning passage 305. (See FIG. 17B).

  The ball guide surface 340a rotates around the front guide shafts 343a and 343c by further retracting and guiding the rear guide shafts 343b and 343d downward by the second guide portion 313b. As a result, the first posture is gradually changed to the second posture.

  As described above, the movable plate 20d is changed in posture from the first posture to the second posture while moving from the advanced position to the retracted position. In particular, in this embodiment, the rear guide shafts 343b and 343d are gradually moved and guided downward by the second guide portion 313b immediately before the retracted position, so that the posture is changed after the ball receiving surface 340a is substantially retracted. . That is, the posture is changed in a state in which the game ball is drawn into the big winning path 305 to some extent.

  Further, of the guide shafts 343a to 343d, the front guide shafts 343a and 343c are guide shafts that are only moved and guided by the first guide portion 313a between the advanced position and the retracted position, and the rear guide shafts. Reference numerals 343b and 343d denote guide shafts that are moved and guided by the first guide part 313a, the second guide part 313b, and the third guide part 313c. That is, the movable plate 20d rotates in the vertical direction and changes its posture as the rear guide shafts 343b and 343d move up and down around the front guide shafts 343a and 343c.

  Of the guide shafts 343a to 343d, only the front guide shaft 343a is a drive transmission shaft connected to the solenoid 21b via the transmission member 302. In the case of the present embodiment, as shown in FIG. 14, the front guide shafts 343a and 343c have substantially the same distance P1 from the rotation shaft 311 in both the advanced position and the retracted position. In the retracted position, the guide shafts 343b and 343d have a distance P2 from the rotation shaft 311 that is longer than the advanced position and a distance P2 that is longer than the distance P1.

  Therefore, the movable plate 20d is stably supported by the rear guide shafts 343b and 343d as guided portions arranged in parallel in the moving direction and the front guide shafts 343a and 343c as auxiliary guided portions. When the guide shafts 343b and 343d on the retracted position side reach the second guide portion 313b, the guide shaft 343a is changed to the second posture by rotating about the guide shafts 343a and 343c on the advanced position side, and the guide shaft 343a. Any of ˜343d also serves as a connecting portion with the transmission member 302, so that not only the number of parts can be reduced and the manufacturing cost can be reduced, but also the transmission member 302 can be made as short as possible to reduce the size of the apparatus.

  Next, based on FIG.17 and FIG.18, the approach condition of the game ball accompanying the closing operation | movement of the 2nd special variable winning ball apparatus 20B is demonstrated.

  When the movable plate 20d is in the advanced position, the ball receiving surface 340a is slightly tilted toward the big winning path 305, so that the game ball that has dropped on the ball receiving face 340a is guided toward the big winning path 305. This works (see FIG. 17A).

  Here, when the movable plate 20d starts the retreat movement from the advance position toward the retreat position side, an external force in the retreat direction is hardly generated in the game ball placed on the flat ball receiving surface 340a during the retreat movement. In many cases, a game ball placed on the ball receiving surface 340a spills out during retraction.

  However, when the game ball placed on the ball receiving surface 340a is guided toward the big winning path 305 side, it is drawn into the big winning path 305 side by the retraction movement of the movable plate 20d, and the rear guide shaft 343b, 343d reaches the second guide 313b and the posture change to the second posture is started, so that the game ball drawn into the entrance of the big prize passage 305 is received by the ball receiving surface 340a changed to the second posture. It is pushed into the back side (see FIG. 17B).

  Next, when the rear guide shafts 343b and 343d move to the lower end of the second guide portion 313b, the movable plate 20d is completely in the second posture, and the opening of the second big winning opening 20c becomes the vertical width dimension L4. Thus, the game ball does not fall down from the second grand prize opening 20c (see FIG. 18A).

  The movable plate 20d stops at the retracted position, and the game ball flows from the first passage 305a into the second passage 305b and is detected by the second count switch 24a (see FIG. 18B).

  Here, in a state where the movable plate 20d is stopped at the retracted position, the cutout portion 342 of the movable plate 20d is positioned directly above the bent portion 305c, that is, the second passage 305b. As described above, the movable plate 20d is stably supported by the guide shafts 343b and 343d as the guided portions arranged in parallel in the moving direction and the guide shafts 343a and 343c as the auxiliary guided portions, and also on the retreat position side. When the guide shafts 343b and 343d reach the second guide portion 313b, the guide shafts 343b and 343d are changed to the second posture by rotating around the guide shafts 343a and 343c on the advance position side. As described above, when the posture of the movable plate 20d is stabilized and the guide shafts 343b and 343d and the guide shafts 343a and 343c are separated as much as possible in order to easily tilt the posture around the guide shafts 343a and 343c, The movable plate 20d becomes long in the moving direction, and the bent portion 305c is closed at the retracted position. However, since the cutout portion 342 is formed, the game ball can flow into the second passage 305b via the cutout portion 342 even when the movable plate 20d is disposed at a position corresponding to the bent portion 305c. Thus, the entered game ball can be detected by the second count switch 24a without making a detour.

  Therefore, since it is possible to immediately detect the game ball that has entered the second grand prize winning opening 20c by the second count switch 24a without increasing the size of the second special variable winning ball apparatus 20B, in step S418. After the winning ball detection waiting time is set, it is possible to shorten the waiting period for the winning ball detection as much as possible in the processing of steps S410 and 420 to 422 (game ball detection waiting time during the round interval). Since it becomes possible to digest at high speed, the operating rate of the pachinko gaming machine 1 can be improved.

  As described above, in the pachinko gaming machine 1 as an embodiment of the present invention, when the movable plate 20d is in the advanced position, the guide shafts 343b and 343d as the guided portions are connected to the first guide portion 313a. By being guided and in the first posture, the game ball is less likely to be drawn into the big prize passage 305 than in the second posture, so that it is possible to suppress the entry rate of the game balls into the big prize passage 305 from being excessively increased.

  On the other hand, when the guide shafts 343b and 343d are guided to the second guide portion 313b during the retreating movement, the movable plate 20d rotates around the guide shafts 343a and 343c and is changed from the first posture to the second posture. When the ball receiving surface 340a is tilted toward the big winning passage 305, the game balls on the ball receiving surface 340a are pushed toward the big winning passage 305. It is possible to prevent the drawn game balls from spilling.

  That is, by changing the posture of the movable plate 20d according to the position, it is possible to adjust the entrance rate of the game ball into the big winning path 305. That is, it is difficult to draw the game ball received in the first posture at the advance position, but the game ball drawn in by the retreating operation can be forced into the big winning path 305 side by changing the posture.

  In addition, when advancing to the advancing position with the second posture, if the amount of movement to the advancing position side is not increased as compared with the case of advancing to the advancing position with the first posture, the frontage that receives the falling game ball is For this reason, it is preferable to advance the first posture and change the posture to the second posture in the middle of the retreat operation, like the movable plate 20d.

  Further, when the movable plate 20d changes its posture immediately after starting the retreating operation, there is a possibility that the game ball that has not yet been drawn into the big winning path 305 will float upward due to the posture change. Therefore, it is preferable to change the posture at the timing of pushing the game ball that has started to be drawn into the big winning path 305 to the back side.

  Specifically, for example, the posture is changed when the protruding length of the ball receiving surface 340a from the second grand prize opening 20c is about ½ or less of the protruding length at the advanced position. It is preferable. Alternatively, it is preferable that the posture is changed when the protruding length of the ball receiving surface 340a from the second grand prize opening 20c is equal to or less than the radius R of the game ball.

  Further, the movable plate 20d assumes the second posture by guiding the guide shafts 343b and 343d to the second guide portion 313b at the retracted position, thereby narrowing the entrance of the big winning path 305 and winning the game ball. Since entry into the passage 305 is prevented, unintentional winnings and illegal winnings are prevented.

  Further, the guide grooves 313L and 313R have a third guide portion 313c formed substantially parallel to the first guide portion 313a on the retracted position side of the second guide portion 313b, and the movable plate 20d is at the retracted position. By guiding the guide shafts 343b and 343d to the third guide portion 313c and maintaining the second posture, even if the end portion on the game area 7 side of the movable plate 20d tilted at the retracted position is pushed down, Since the rotation of the guide shafts 343b and 343d is restricted by the third guide portion 313c, an illegal act such as forcibly moving the movable plate 20d out of the big winning path 305 can be suppressed.

  The big winning path 305 includes a second path 305b extending downward from a bent portion 305c formed on the retreat position side, and a second count switch 24a for detecting a game ball flowing down the second path 305b. The movable plate 20d protrudes from the guide shafts 343b and 343d toward the advance position and is guided only by the first guide portion 313a between the advance position and the retracted position. The guide shafts 343a and 343c have a notch portion 342 through which a game ball can pass at a position corresponding to the bent portion 305c in the retracted position, and the guide shaft 343b is located at a position corresponding to the notch portion 342. , 343d is provided so that the movable plate 20d is stably supported by the guide shafts 343b, 343d and the guide shafts 343a, 343c arranged in parallel in the moving direction. , The guide shaft 343b of the retracted position, the 343d comes to the second guide portion 313b, the guide shaft 343a of the advanced position, is changed to the second posture by pivoting around the 343c.

  In this way, the posture of the movable plate 20d is stabilized, and the guide shafts 343b and 343d and the guide shafts 343a and 343c are connected as much as possible in order to easily tilt the posture around the guide shafts 343a and 343c as auxiliary guided portions. If it is attempted to separate, the movable plate 20d becomes long in the moving direction, and the bent portion 305c is closed at the retracted position, but even if the movable plate 20d is disposed at a position corresponding to the bent portion 305c, Since the game ball can flow into the second passage 305b through the notch 342, the entered game ball can be detected by the second count switch 24a without making a detour.

  In the present embodiment, the notch 342 is formed in the rear part of the movable plate 20d. However, for example, an opening (hole) may be used as long as it can pass the game ball.

  In addition, the ball receiving surface 340a has a bent portion 340d as a tip side inclined portion that tilts toward the big winning path 305 at the tip of the advance position, so that the ball receiving surface 340a at the advance position Not only can the received game ball be prevented from spilling from the tip, but also the game ball is less likely to spill from the tip when retreating. Furthermore, it becomes difficult for a game ball to enter because the tip portion is inclined upward at the retracted position.

  In the present embodiment, the ball receiving surface 340a is formed flat in the width direction (left-right direction) orthogonal to the movement direction, but in the width direction (left-right direction) orthogonal to the movement direction. You may provide the width direction inclination part (illustration omitted) which inclines upward toward the both end sides from a substantially center. By doing in this way, the game ball received in the advance position can be made difficult to spill from the end in the width direction.

  The driving means includes a solenoid 21b disposed in the main body 300 of the second special variable winning ball apparatus 20B, one end connected to the solenoid 21b and the other end connected to the movable plate 20d. A movable member 20d that is rotatably provided around a rotation shaft 311. The movable plate 20d projects from the guide shafts 343b and 343d toward the advanced position, and includes an advanced position and a retracted position. Guide shafts 343a and 343c guided only by the first guide portion 313a, and the other end of the transmission member 302 is located at the advanced position of the movable plate 20d among the guide shafts 343b and 343d and the guide shafts 343a and 343c. When the movable plate 20d is connected to the guide shafts 343a to 343d located closest to the rotation shaft 311 when in the retracted position, the movable plate 20d is arranged in parallel with the moving direction. 43b, 343d and guide shafts 343a, 343c are stably supported, and when the retracted position side guide shafts 343b, 343d reach the second guide portion 313b, the advancing position side guide shafts 343a, 343c are the center. By rotating, the position is changed to the second posture, and any one of the guide shafts 343b and 343d and the guide shafts 343a and 343c also serves as a connecting portion with the transmission member 302, thereby reducing the number of parts and reducing the manufacturing cost. In addition, the transmission member 302 can be made as short as possible to reduce the size of the apparatus.

  Further, since the transmission member 302 is covered with the left cover 301a of the cover member 301 that covers the main body 300 from the outside, the transmission member 302 is illegally operated from the outside to operate the movable plate 20d. Can be suppressed.

  Further, the transmission member 302 is disposed in a space formed between the main body 300 and the left cover 301 a, and at least the left end of the rotation shaft 311 is pivotally supported by the bearing 330. Even if the left cover 301a is removed and the transmission member 302 is manipulated from the outside to operate the movable plate 20d, the rotation support state of the transmission member 302 is released by removing the left cover 301a, and the rotation operation is performed. Since it becomes unstable, cheating can be prevented.

  In this embodiment, the posture change is performed immediately before the retracted position, but the posture change position can be variously changed between the advanced position and the retracted position. That is, as long as the second guide portion 313b is formed between both ends in the longitudinal direction of the guide grooves 313L and 313R, the formation position is arbitrary.

  In this embodiment, the second posture is maintained at the retracted position. However, if the posture is changed during the retracting operation, the second posture is not necessarily maintained at the retracted position. It does not have to be done.

  In this embodiment, the movable plate 20d is supported on the left and right sides by the guide shafts 343b and 343d as the guided portions and the guide shafts 343a and 343c as the auxiliary guide portions. May be provided in the left and right respectively.

  Although not particularly illustrated, for example, the rear end of the movable plate 20d is connected to driving means such as a solenoid via a connecting shaft facing in the left-right direction, and only the guide shaft as a guided portion is guided to the guide grooves 313L and 313R. You may do it.

  In this embodiment, the guide portion of the present invention is constituted by one guide groove 313L, 313R on each of the left and right sides, and guide shafts 343b, 343d as guided portions and guide shafts 343a, auxiliary guided portions. The guide shafts 343b and 343d and the guide shafts 343a and 343c may be configured as separate guide grooves, respectively, although the guide shafts 343b and 343d are guided by the same guide grooves 313L and 313R.

  Specifically, for example, as shown in FIG. 20, the first guide groove 370 for guiding the rear guide shafts 343b and 343d and the second guide groove 371 for guiding the front guide shafts 343a and 343c are configured. However, it is also possible to guide the movement with separate guide grooves 370 and 371.

  In this case, the second guide groove 371 that moves and guides the front guide shafts 343a and 343c extends in the moving direction (front-rear direction) of the movable plate 20d, and the first guide portion 371a is extended. A second guide portion 371b provided on the rear side of the portion 371a and inclined upward with respect to the first guide portion 371a, and a rear side of the second guide portion 371b and substantially parallel to the first guide portion 371a. Since the movable plate 20d rotates around the rear guide shafts 343b and 343d, the posture is changed. Thus, the rotation center for changing the attitude of the movable plate 20d may be any of the center position, the rear side, and the front side in the front-rear direction of the movable plate 20d.

  That is, in this case, the rear guide shafts 343b and 343d constitute a connecting portion and an auxiliary guided portion that are connected to the solenoid 21b via the transmission member 302, and the front guide shafts 343a and 343c are to be changed in posture. It constitutes a guide part.

  The second guide portion 371b is inclined upward toward the rear side, and is different from the second guide portion 313b inclined downward toward the rear side. That is, the inclination direction of the second guide portion can be variously changed.

  In this embodiment, the guide shafts 343b and 343d as the guided portions are formed on the movable plate 20d side, and the guide grooves 313L and 313R as the guide portions are formed on the main body portion 300 side. Guide grooves 313L and 313R as guide portions may be formed on the side, and guide shafts 343b and 343d as guide portions may be formed on the main body portion 300 side.

  Further, in this embodiment, the guide groove and the guide shaft are applied as an example of the guide portion and the guided portion. However, for example, a guide rail is applied as another example of the guide portion, and another example of the guided portion. A fitting member or the like that is slidably fitted to the guide rail may be applied.

  In this embodiment, the guide grooves 313L and 313R as the guide portions and the guide shafts 343b and 343d as the guided portions are applied as the posture changing means for changing the posture of the movable plate 20d. If the posture can be changed during the retreat movement, the posture may be changed by means other than the guide groove and the guide shaft.

  Further, in this embodiment, the posture is changed in the middle of the operation in both the advancing operation and the retracting operation. However, if the posture is changed at least only in the retracting operation, the posture is changed in the middle of the advancing operation. You may comprise so that an attitude | position may not be changed.

  Further, the driving means of the movable plate 20d is not limited to the transmission member provided so as to be rotatable with the solenoid. For example, a motor is applied as a driving source and the driving force of the motor is transmitted by a gear member or the like. It may be possible to move forward / backward and change the posture by doing (for example, rack and pinion).

  Next, a second special variable winning ball device 20B 'as a modified example will be described with reference to FIGS. 21A is a perspective view showing a movable plate as a modification, FIG. 21B is a plan view, FIG. 21C is a sectional view taken along line EE in FIG. 21B, and FIG. It is F sectional drawing. 22A is a cross-sectional view of the second special variable winning ball apparatus in the open state, FIG. 22B is a cross-sectional view of the second special variable winning ball apparatus in the closed state, and FIG. 22C is a view showing the guide groove. is there. FIG. 23 is a cross-sectional view showing a game ball entering state when the movable plate of FIG. 21 is retracted from the advanced position to the retracted position.

  In addition, about 2nd special variable winning ball apparatus 20B 'as a modification, the illustration and description regarding a different part from 2nd special variable winning ball apparatus 20B are shown, and the same code | symbol is attached | subjected about the same component. The description will be omitted.

  The movable plate 20d ′ of the second special variable winning ball apparatus 20B ′ includes a ball receiving portion 340 having a ball receiving surface 340a for receiving a game ball on the upper surface, and extends from the left and right sides of the ball receiving portion 340 toward the rear side. And a bifurcated guided portion 341 provided. The difference from the movable plate 20d is that the shape of the ball receiving portion 340 and the front and rear guide shafts 343a, 343b, 343c, 343d are connected by plate-like connecting members 360a, 360b.

  As shown in FIG. 21 (b), the ball receiving portion 340 has corners between the inclined surfaces 340b and 340c and the left and right sides formed in a curved shape, and is substantially in the front-rear direction on the ball receiving surface 340a. A region on the front side of the center position is a bent portion 340d that bends upward toward the tip side rather than the rear side. In this way, the bent portion 340d having a larger inclination angle than the rear side is formed on the front end side of the ball receiving portion 340, so that the game ball received on the front end side of the ball receiving surface 340a is on the second big prize opening 20c side. Therefore, the game ball can be easily drawn during the retreat movement.

  The front and rear guide shafts 343a and 343b are connected by a plate-like connecting member 360a, and the front and rear guide shafts 343c and 343d are connected by a plate-like connecting member 360b. As a result, the strength of the guide shafts 343a, 343b, 343c, and 343d increases, so that damage due to an impact when receiving a game ball is prevented. In addition, the notch recessed part 360c is formed in the connection member 360a, and interference with the transmission member 302 in which the guide shaft 343a is inserted is avoided.

  As shown in FIGS. 22A to 22C, the guide grooves 313L ′ and 313R ′ are formed in a straight line, and are extended so as to be inclined slightly downward from the advance position side toward the retracted position side. Yes.

  That is, the movable plate 20d ′ of the second special variable winning ball apparatus 20B ′ of the present modification is moved back and forth between the advanced position (see FIG. 22A) and the retracted position (see FIG. 22B). Since it moves only in a straight line and does not change the posture, it is always supported in the same posture between the advanced position and the retracted position.

  Next, based on FIG. 23, the entering situation of the game ball accompanying the closing operation of the second special variable winning ball device 20B 'will be described.

  When the movable plate 20d ′ is in the advanced position, the ball receiving surface 340a is slightly tilted toward the big winning path 305 and the bent portion 340d is formed on the tip side of the ball receiving surface 340a. The game ball that has fallen on the surface 340a has an action that is guided toward the prize winning path 305 (see FIG. 23A).

  Here, when the movable plate 20d starts the retreat movement from the advance position toward the retreat position side, the game ball placed on the ball receiving surface 340a during the retreat movement is moved by the bent portion 340d moving from the front end side. Since it is pushed toward the retreat position side, the game ball is less likely to spill out compared to a flat tip. The movable plate 20d 'stops at the retracted position, and the game ball flows into the second passage 305b from the first passage 305a and is detected by the second count switch 24a (see FIG. 23B).

  In the present embodiment, the example in which the present invention is applied to the second special variable winning ball apparatus 20B has been described. However, the present invention also applies to the first special variable winning ball apparatus 20A, the variable winning ball apparatus 15 and other winning holes. Is applicable.

  Next, it is an example of a movement direction changing member that is arranged so as to obstruct the movement of the game ball launched into the game area 7 and changes the movement direction of the game ball. The upper wall member 700 provided on the center frame decoration 11 (see FIG. 1) and provided with the metal plate 750 will be described with reference to FIGS.

Make up a moving direction changing member.

  Further, the outer rail decorations 600a to 600c are arranged around the game area 7 on the game board surface 6a, so that the end portions of the guide surfaces 601a to 601c each having an arc shape in front view standing on the game board surface 6a. They are connected to each other to form an annular guide surface. In addition, the outer rail 401 is arrange | positioned along the inner side of a part of guide surface 601a, 601b, and comprises the guide surfaces 601a and 601b substantially. A part of the inner rail 402 is disposed along the inside of a part of the guide surface 601c, and substantially constitutes a part of the guide surface 601c.

  Thus, by these guide surfaces 601a to 601c, the game board surface 6a is partitioned into a substantially circular game region 7 formed at the center and a non-game region formed around the game region 7a. The 600 c, the outer rail 401, and the inner rail 402 constitute a rail member that forms the game area 7.

  The shot ball guiding passage 400 (shaded area in FIG. 24) is an upper part of the game area 7 from the ball hitting device 450 provided at the lower right side of the game area 7 (dotted area in FIG. 24) formed in the game board 6. An arcuate portion extending so as to wrap around the left peripheral edge of the game area 7 toward the left side so that the game ball launched from the hitting ball launching device 450 is turned toward the upper part of the game area 7 It is formed to guide.

  The connecting portion 410 that connects the shot ball guide passage 400 and the game area 7 is provided with a return ball prevention device 500 to prevent a game ball that has entered the game area 7 from returning to the shot ball guide path 400. Has been. Further, in the present embodiment, the game ball emitted from the launch ball guiding passage 400 into the game area 7 through the connecting portion 410 is emitted obliquely upward to the right.

  As shown in FIGS. 25 and 26, the upper wall member 700 has a plate-like attachment portion 701 attached to the game board surface 6a and an opening on the lower surface so as to obstruct the movement of the game ball on the front surface of the attachment portion 701. And a block portion 702 formed in a box shape. The left side surface 703 of the block unit 702 is composed of a vertical surface 703a facing upward and downward, and a curved surface 703b curved downward from the lower end thereof toward the left side. The game ball that is driven into the game area 7 is returned to the left area 7a. The right side 704 is a vertical plane, and a horizontal plate 705 extends from the lower end toward the right.

  A V-shaped groove 707 facing in the left-right direction is formed at a substantially central position in the front-rear direction on the upper surface 706 of the block portion 702, and a slit 708 is formed in a V-shape on the inner surface of the V-shaped groove 707 slightly on the left side. Is formed. Further, the block portion 702 is formed in a box shape having an opening at the bottom, and a metal plate 750 is assembled with screws 709 from the lower surface opening so that a part thereof is exposed from the slit 708.

  The upper surface 706 is divided into a rear upper surface 706a and a front upper surface 706b by a V-shaped groove 707 facing in the left-right direction. The rear upper surface 706a and the front upper surface 706b are inclined surfaces inclined downward toward the V-shaped groove 707, respectively.

  The metal plate 750 has a predetermined plate thickness (for example, about 1 mm) and is formed by bending a predetermined portion. Specifically, a rear piece 711 that is set up substantially vertically and faces in the front-rear direction, and a front piece 712 that is bent at the front side of the rear piece 711 so as to incline to the left with respect to the rear piece 711 toward the front. And a mounting piece 713 that is bent substantially horizontally from the lower end of the rear piece 711 toward the right side. A mounting hole 714 for a screw 709 is formed in the mounting piece 713.

  The front piece 712 includes a lower front piece 712a and an upper front piece 712b connected to the upper portion of the lower front piece 712a. The upper front piece 712b is divided with respect to the rear piece 711 by forming a notch groove 715 between the upper piece 711b and bent so as to incline to the right with respect to the lower front piece 712a. Has been. Therefore, a substantially V-shaped cut groove 715 is formed between the rear piece 711 and the upper front piece 712b when viewed from the front.

  Further, the front edge E1 on the cut groove 715 side of the rear piece 711 is an inclined edge inclined downward toward the front side, and the front edge E2 on the cut groove 715 side of the upper front piece 712b is directed downward toward the rear side. The slanted edge is slanted.

  Next, the situation when a ball with a thread used for fraud is launched from the ball striking device 450 will be described with reference to FIG.

  Conventionally, for example, one end of a transparent nylon thread such as a fishing line is bonded to a game ball or a transparent synthetic resin ball, and the ball with the thread is launched into the game area 7 by a hitting ball launcher 450, and the thread at hand is fed out or pulled back. It is possible to repeatedly win a ball with a thread by operating it, or to place the launched ball with a thread on a place (such as a warp entrance or a windmill) that can affect the flow-down direction of a game ball (so-called ball hitting). In some cases, illegal acts such as making it easier for a game ball to be guided to the mouth or the like.

  Here, an example of fraud using a threaded ball will be briefly described.

  As shown in FIG. 27, a ball-striated ball P in which one end of the thread T is bonded by an adhesive or the like is sent out to the ball-hitting ball-emitting device 450, and the other end of the yarn T is left without being sent out. When launched at 450, the ball with thread P passes through the connecting portion 410 from the firing ball guiding passage 400 and is emitted to the game area 7 (here, the right area 7b). Following the movement of the threaded ball P, the thread T is pulled out.

  As shown in FIG. 28, the front-rear width dimension L10 in the vicinity of the block portion 702 is wider than the diameter 2R of the threaded ball P, and the separation width dimension L11 between the game board surface 6a and the rear surface 102a ′ of the see-through window 102a. Is also short (L11> L10> 2R). The length obtained by subtracting the front-rear width dimension L10 from the separation width dimension L11 is shorter than the diameter 2R of the threaded ball P (L11-L10 <2R).

  Therefore, the threaded ball P is surely in contact with the upper surface 706 when passing through the block portion 702, that is, passes through a position above the upper surface 706. More specifically, when the threaded ball P abuts against the game board surface 6a and when the threaded ball P abuts against the back surface 102a ′ of the see-through window 102a, the center of the threaded ball P is at a position corresponding to one of the upper surfaces 706a and 706b. is there. Therefore, the thread T drawn out following the threaded ball P passing through the upper position of the block portion 702 is pulled out at the upper position of the upper surface 706.

  Here, for example, when it is attempted to illegally obtain the winning ball by repeatedly winning the ball with thread P in the second start winning opening 13b, the gaming ball is launched aiming at the right region 7b. The threaded ball P emitted obliquely upward to the right from the connecting portion 410 provided at the upper left position of the game area 7 is guided to the right area 7b by passing between the upper portion of the block 702 and the guide surface 601a. The If the momentum is weak, it collides with the left side 703 and is guided to the left region 7a.

  Then, when the threaded ball P flowing down the right region 7b enters, for example, the winning opening 29d and is detected by the winning opening switch 30b provided in the winning opening 29d, the feeding of the thread T at hand is stopped and the thread is stopped. After the flow of the attached ball P is regulated, the thread T is pulled back to cause the threaded ball P to flow backward and pulled out to the upstream side of the winning opening 29d. Here, generally, the winning opening switch 30b is provided in the winning passage in the winning opening, so that the threaded ball P does not have to be pulled up from the winning opening switch 30b, and only the reverse flow is made to the upstream side of the winning opening switch 30b. It's okay.

  In this way, by repeating the series of operations such that the thread T is fed out again and detected by the winning opening switch 30b and then pulled back, the threaded ball P is detected by the winning opening switch 30b many times and illegally. You can get a prize ball. Further, for example, in the case of the second start winning opening 13b, the right to start the change of the second special figure game can be obtained.

  Although not shown in particular, for example, an illegal act (for example, hooking (clogging) a ball P with a thread between the warp entrance of the stage frame or the obstacle nail so that the game ball is easily guided to a predetermined winning opening or the like ( When performing so-called ball hooking, the threaded ball P may be launched in the same manner as described above, and the thread T may be stopped at a predetermined position in the game area 7 and the threaded ball P may stay there.

  As described above, when the threaded ball P driven into the game area 7 flows down and then the feeding of the thread T is stopped, the thread T is tensioned by its own weight.

  Specifically, as shown in FIG. 27 (b), the thread T drawn from the launch ball guiding passage 400 to the connecting portion 410 at the top of the game area 7 is located at the upper approximate center position of the game area 7. The wall member 700 is folded downward and extends to the lower part of the right region 7b. Thus, the threaded ball P that moves upward in the firing ball guide passage 400 and is emitted obliquely upward to the right from the connecting portion 410 into the game area 7 is folded downward by the upper wall member 700 by its own weight. Then, since the yarn naturally flows down to a position below the upper wall member 700, the yarn T is suspended from the upper wall member 700 by stopping the feeding of the yarn T, and tension is generated in the yarn T. . Therefore, the thread T is caught on the metal plate 750 by flowing after the threaded ball P passes through the upper position of the block portion 702.

  As shown in FIG. 28, the threaded ball P passes through the upper position of the block portion 702 and is emitted to the right region 7b, and then flows down to a position lower than the upper wall member 700, whereby the rear upper surface 706a and the front The thread T is applied to one of the leading edges E1 and E2 of the metal plate 750 exposed in the upper surface 706b or the cut groove 715. At this time, the leading edges E1 and E2 are inclined downward toward the cut groove 715, so that the thread T is guided to the cut groove 715 as the tension increases.

  Then, when the thread T is tensioned, the thread T bites in toward the base of the notch groove 715, so that the thread T is formed by the edges of the rear piece 711 and the upper front piece 712 b constituting the notch groove 715. Is held so as to meander back and forth, and movement of the yarn T, such as feeding and pulling out the yarn T, is restricted, so that the threaded ball P cannot be repeatedly detected by the second start port switch 15a. That is, the cut groove 715 forms a movement restricting portion that restricts the movement of the yarn T.

  Further, when a stronger tension is generated, an action similar to that of scissors occurs, and the thread T may be cut at the edge of the cut groove 715. When the yarn T is cut in this way, the operation of the yarn T such as feeding and pulling out the yarn T cannot be performed, so that the threaded ball P cannot be repeatedly detected by the second start port switch 15a. That is, the cut groove 715 constitutes a cutting portion for cutting the yarn T.

  As described above, since the cut groove 715 is provided in the upper wall member 700, as a fraudulent act, the ball P with the thread is launched while the other end of the thread T attached to the game ball is held. Even when it is launched by the device 450 and illegally enters the right region 7b from the launch ball guiding passage 400 via the connecting portion 410, not only the tension of the yarn T is caused by the weight of the yarn-attached ball P, but also the yarn T is pulled back. By repeating the above, it becomes easy to restrict the cutting or movement of the thread T by the cut groove 715, so that it is possible to prevent an illegal act by the threaded ball.

  Further, the cut groove 715 may be a cutting portion that cuts the yarn T, may be a movement restricting portion that restricts the movement of the hooked yarn T in the feed-out or pull-back direction, or the first The movement of the yarn T may be restricted by applying the force of, and the yarn T may be cut when a second force greater than or equal to the first force is applied.

  Further, since the cut groove 715 is provided in the upper wall member 700 provided in the passage for guiding the game ball to the right region 7b, the thread T following the moving ball with thread P can be cut into the cut groove 715. It becomes easy to be guided to. Further, since the tension is easily applied by being provided at the upper position of the right region 7b, not only the thread T is easily hooked but also the manipulation is difficult even if the thread T is pulled back.

  Further, in this embodiment, the cut groove 715 is formed by cutting the cut groove from the front end portion of the metal plate 750. However, as the cut groove becomes thinner as much as possible, Since the edges of 711 and the upper front piece 712b come closer to each other, the thread T becomes easier to meander as it goes to the base side of the cut groove 715, so that it becomes easier to catch and burrs or the like are generated on the edge during the cutting process. , Resistance to the yarn T is easily imparted.

  The metal plate 750 includes a rear piece 711 and a front piece 712 arranged in the front-rear width direction. The front piece 712 is inclined to the left side toward the front with respect to the rear piece 711, and The front piece 712b is inclined rightward toward the upper side with respect to the lower front piece 712a, and a notch groove 715 is formed between the rear piece 711 and the upper front piece 712b. The edges of the upper front piece 712b are shifted from each other and the opening of the cut groove 715 is widened, so that the yarn T is easily guided to the cut groove 715.

  In this way, it is easy to guide the thread T into the cutting groove 715 by widening the opening in the moving direction (left and right direction) of the thread T without expanding the front and rear width direction opening of the cutting groove 715. In addition, the yarn can be easily held or cut in the cut groove 715.

  Such a metal plate 750 may be provided on a member other than the upper wall member 700.
