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

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

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

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

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

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

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

  A variable winning ball device 15 having a second starting winning port 13b through which a game ball can be won is provided below the winning device having the first starting winning port (first starting port) 13a. The game ball that has won the second start winning opening (second start opening) 13b is guided to the back of the game board 6 and detected by the second start opening switch 15a and the second winning confirmation switch 15b.

When the variable winning ball apparatus 15 is in the open state, the game ball can be won in the second start winning opening 13b (it is easy to start winning), which is advantageous for the player. In a state where the variable winning ball device 15 is in the open state, it is easier for the game ball to win the second starting winning port 13b than the first starting winning port 13a. In addition, in a state where the variable winning ball device 15 is in the closed state, the game ball does not win the second start winning opening 13b. In the state where the variable winning ball device 15 is in the closed state, it may be configured that the winning is possible (that is, it is difficult for the gaming ball to win) although it is difficult to win a prize.

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

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

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

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

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

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

Yes. The game ball that has won the first big prize opening 23c is guided to the back of the game board 6 and detected by the first count switch 23a and the third prize confirmation switch 23b.

  A specific gaming state that occurs when a specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a and when a specific display result (big hit symbol) is derived and displayed on the second special symbol display 8b In the (hit game state), the first prize-winning port 23c, which is a prize-winning area, is opened by the solenoid 21 controlling a prize-winning door 704 (see FIG. 32), which will be described later, to an open state. When the first special variable winning ball device 23 is in the open state, the game ball can be won in the first big winning opening 23c (it is easy to win), which is advantageous to the player. In a state where the first special variable winning ball apparatus 23 is in the open state, it is easy for a game ball to win the first big winning opening 23c. In addition, when the grand prize winning door 704 (see FIG. 32) is closed, the game ball does not win the first big prize winning opening 23c. It should be noted that when the grand prize opening door 704 (see FIG. 32) is in the closed state, it is difficult to win, but it is possible to win (that is, it is difficult for the game ball to win). May be.

  Further, the presence / absence of an abnormal winning is determined based on the detection results of the first count switch 23a and the third winning confirmation switch 23b, and a security signal is externally output based on the detection of the abnormal winning.

  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 23c opened in the first special variable winning ball apparatus 23, for example, the first starting winning opening 13a and the second starting winning opening 13b, etc. More prize balls are paid out than when a game ball passes (enters) through the prize opening. Accordingly, if the first special winning opening 23c is opened in the first special variable winning ball apparatus 23, the first state is advantageous for the player. On the other hand, if the first special winning opening 23c is closed in the first special variable winning ball apparatus 23, the game ball cannot pass through (enter) the first big winning opening 23c and a prize ball cannot be obtained. The second state is disadvantageous for the player.

  Further, on the upper left side of the effect display device 9, a second special variable winning ball device 24 having a second big winning port 24c through which a game ball can be won is provided. The game ball that has won the second grand prize opening 24c is guided to the back of the game board 6, and is detected by the second count switch 24a and the fourth winning confirmation switch 24b.

  A specific gaming state that occurs when a specific display result (big hit symbol) is derived and displayed on the first special symbol display 8a and when a specific display result (big hit symbol) is derived and displayed on the second special symbol display 8b In the (big hit game state), the solenoid member 22 controls the blade member 600 (see FIG. 21) to be in the open state, thereby opening the second big prize opening 24c serving as a winning area, and the game ball becomes the second big prize. It becomes possible to win a prize in the mouth 24c (it becomes easier to win), which is advantageous to the player. In a state where the second special variable winning ball device 24 is in the open state, it is easy for a game ball to win the second big winning port 24c. Further, when the blade member 600 (see FIG. 21) is in the closed state, the game ball does not win the second grand prize opening 24c. In the case where the second special variable winning ball device 24 is in the closed state, although it is difficult to win, it is possible to win (that is, it is difficult for the game ball to win). Good.

  Further, the presence / absence of an abnormal winning is determined based on the detection results of the second count switch 24a and the fourth winning confirmation switch 24b, and a security signal is output to the outside based on the detection of the abnormal winning.

  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 big prize opening 24c that has been opened in the second special variable prize ball apparatus 24, for example, the first start prize opening 13a and the second start prize 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 variable winning ball device 24 is in the open state, the first state is advantageous for the player. On the other hand, if the second special winning opening 24c is closed in the second special variable winning ball apparatus 24, the game ball cannot pass through (enter) the second large winning opening 24c and a prize ball cannot be obtained. The second state is disadvantageous for the player.

  Also, one terminal of the first start port switch 14a (hereinafter, the second start port switch 15a, the first count switch 23a, and the second count switch 24a are the same, but the description is omitted), which is a proximity switch. The + 12V power supply voltage is supplied from the power supply board. A detection signal that is the voltage level of the other terminal of the first start port switch 14 a is input to the main board 31. In the main board 31, the detection signal is input from the input driver circuit to the input port of the game control microcomputer. A resistor R and a capacitor C, one end of which is grounded, are connected to the output side of the first start port switch 14a.

  When a metal game ball passes through a hole provided in the first start port switch 14a that is a proximity switch, a counter electromotive force is generated in the coil, and the equivalent resistance value of the coil becomes extremely large. Accordingly, the output of the first start port switch 14a becomes a low level close to 0V. That is, the detection signal is at a low level. When the metal game ball does not pass through the hole provided in the first start port switch 14a, the output of the first start port switch 14a is + 12V divided by the resistance value of the coil and the resistor R. The value exceeds a threshold level that is considered high. That is, the detection signal is at a high level. Therefore, in this embodiment, the game control microcomputer can determine that the first start port switch 14a is in the OFF state if the output from the first start port switch 14a is at a high level. If the output from the mouth switch 14a is at a low level, it can be determined that the first start port switch 14a is in the ON state (that is, the output of the first start port switch 14a is negative logic). The detection signal level may be logically inverted by an input driver circuit and then input to the game control microcomputer 156.

  The first winning confirmation switch 14b (hereinafter referred to as the second winning confirmation switch 15b, the third winning confirmation switch 23b, and the fourth winning confirmation switch 24b, which is a photo sensor) is a light emitting diode that emits light. (LED) and a phototransistor that receives light and outputs a current. When the game ball passes in the vicinity of the light emitting diode and the phototransistor, the phototransistor receives light from the light emitting diode reflected by the game ball and causes a current to flow to the output side. In this case, since a current flows from the collector terminal of the phototransistor to the emitter terminal, the detection signal of the photosensor is negative logic as in the proximity switch. The output side of the photosensor is connected to the main board 31, and the detection signal of the photosensor is input from the input driver circuit to the input port of the game control microcomputer. When a current flows to the output side of the photosensor (specifically, the output side of the phototransistor), the input driver circuit outputs a high-level detection signal to the game control microcomputer. As with the proximity switch, the level of the detection signal may be logically inverted by an input driver circuit and then input to the game control microcomputer 156. When the detection signal from the input driver circuit is at a low level, the game control microcomputer 156 can determine that the game ball has passed the photo sensor.

  The normal symbol display 10 is provided on the right side of the first special symbol display 8a. The normal symbol display 10 is composed of, for example, two lamps. When the game ball passes through the gate 32 and is detected by the gate switch 32a, variable display of the normal symbol display 10 is started. In this embodiment, variable display is performed by alternately lighting the upper and lower lamps (the symbols can be visually recognized when turned on). For example, if the lower lamp is turned on at the end of the variable display, it is a hit. When the lamp on the lower side of the normal symbol display 10 is turned on and it is a win, the variable winning ball device 15 is opened for a predetermined number of times. That is, the state of the variable winning ball device 15 is a state that is advantageous from a disadvantageous state for the player when the lower lamp is lit (a state in which a game ball can win the second start winning opening 13b). ). An upper part of the special symbol storage memory display 18 is provided with a normal symbol storage memory display 41 having four display portions (for example, four segments among seven segment LEDs) for displaying the number of winning balls that have passed through the gate 32. It has been. Each time there is a game ball passing through the gate 32, that is, every time a game ball is detected by the gate switch 32a, the normal symbol storage memory display 41 increases the number of display units to be turned on by one. Then, each time the variable display of the normal symbol display 10 is started, the number of display units that are lit is reduced by one.

  In addition, the normal symbol holding memory display 41 composed of 7 segment LEDs has four display units (segments) for displaying the number of winning balls that have passed through the gate 32, and the first special variable winning ball device 23 at the time of big hit, There are provided two display parts (segments) indicating the number of times the second special variable winning ball apparatus 24 is opened (number of big hit rounds) and two display parts (segments) indicating the gaming state. You may comprise by the indicator different from a symbol reservation memory | storage display part. 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.

  Further, the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the first count switch 23a and the third winning confirmation switch 23b, the second count switch 24a and the second count switch 24a. Different detection system switches are used as the 4-winning confirmation switch 24b. In this embodiment, proximity switches are used as the first start port switch 14a, the second start port switch 15a, the first count switch 23a, and the second count switch 24a, and the first winning confirmation switch 14b, the second winning confirmation switch 15b, Photosensors are used as the third winning confirmation switch 23b and the fourth winning confirmation switch 24b.

  Further, based on the detection of the game ball by the first start port switch 14a, the first special symbol variation display is started, and the prize ball payout is executed. Further, based on the fact that the game ball is detected by the second start port switch 15a, the display of the variation of the second special symbol is started, and a prize ball payout is executed. Also, a prize ball payout is executed based on the detection of the game ball by the first count switch 23a and the second count switch 24a. In addition to the detection result of the first start port switch 14a, whether or not an abnormal winning has occurred is determined based on the detection result of the first winning confirmation switch 14b, and the security signal is generated based on the detection of the abnormal winning. Output externally. In addition to the detection result of the second start opening switch 15a, the presence / absence of an abnormal winning is determined based on the detection result of the second winning confirmation switch 15b, and the security signal is generated based on the detection of the abnormal winning. Output externally. In addition to the detection result of the first count switch 23a, the presence / absence of occurrence of an abnormal winning is determined based on the detection result of the third winning confirmation switch 23b, and the security signal is generated based on the detection of the occurrence of the abnormal winning. Is output. In addition to the detection result of the second count switch 24a, the presence / absence of an abnormal winning is determined based on the detection result of the fourth winning confirmation switch 24b, and the security signal is generated based on the detection of the abnormal winning. Is output. Accordingly, the first winning confirmation switch 14b, the second winning confirmation switch 15b, the third winning confirmation switch 23b, and the fourth winning confirmation switch 24b are used only for determining an abnormal winning.

  As described above, the first start port switch 14a, the second start port switch 15a, the first count switch 23a, and the second count switch 24a are configured using proximity switches, and the first to fourth winning check switches 14b, 15b, Although the photo sensors 23b and 24b are used, the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the first count switch 23a and the third winning confirmation The detection methods of the switch 23b, the second count switch 24a, and the fourth winning confirmation switch 24b are not limited to those shown in this embodiment. For example, the first and second start port switches 14a and 15a and the first and second count switches 23a, 24a and the first to fourth winning confirmation switches 14b, 15b, 23b, 24b are different detection methods. Conversely, photosensors are used as the first and second start port switches 14a and 15a and the first and second count switches 23a and 24a, and proximity switches are used as the first to fourth winning confirmation switches 14b, 15b, 23b and 24b. May be. In this case, a special symbol variation display and a prize ball payout process are executed based on the detection results of the first and second start port switches 14a and 15a and the first count switch 23a and the second count switch 24a, which are photosensors. The detection results of the first to fourth winning confirmation switches 14b, 15b, 23b, and 24b, which are switches, are the results of the first starting winning port 13a, the second starting winning port 13b, the first major winning port 23c, and the second major winning port 24c. It will be used only for the determination of abnormal winnings. Also, for example, instead of a proximity switch or an optical photosensor that is an electromagnetic switch, the first and second start port switches 14a and 15a and the first and second count switches 23a and 24a are first to fourth winning confirmation switches. Mechanical switches (such as microswitches) may be used as 14b, 15b, 23b, and 24b.

  In this embodiment, the first and second start opening switches 14a and 15a and the first and second count switches 23a and 24a, which trigger the execution of the special symbol change display and the winning ball payout process, are used for determining an abnormal winning. Although the first to fourth winning confirmation switches 14b, 15b, 23b, and 24b used are provided on the upstream side, they may be provided on the downstream side of the switch used for determining the abnormal winning.

  Then, the game control microcomputer 156 uses the first start port switch based on the detection signal input from the first start port switch 14a (proximity switch) and the detection signal input from the first winning confirmation switch 14b (photo sensor). If it is determined that the difference between the number of game balls detected at 14a and the number of game balls detected at the first winning confirmation switch 14b exceeds a predetermined threshold, a predetermined error is given to the first start winning opening 13a. It is determined that an abnormal winning has occurred. The game detected by the second start port switch 15a based on the detection signal input from the second start port switch 15a (proximity switch) and the detection signal input from the second winning confirmation switch 15b (photo sensor). If it is determined that the difference between the number of balls and the number of game balls detected by the second winning confirmation switch 15b exceeds a predetermined threshold value, it is determined that an abnormal winning to the second start winning port 13b has occurred as a predetermined error. To do.

  Based on the detection signal input from the first count switch 23a (proximity switch) and the detection signal input from the third winning confirmation switch 23b (photo sensor), the number of game balls detected by the first count switch 23a and the first If it is determined that the difference from the number of game balls detected by the 3-winning confirmation switch 23b exceeds a predetermined threshold, it is determined that an abnormal winning to the first grand prize opening 23c has occurred as a predetermined error. The number of game balls detected by the second count switch 24a based on the detection signal input from the second count switch 23a (proximity switch) and the detection signal input from the fourth winning confirmation switch 24b (photo sensor). And the number of game balls detected by the fourth winning confirmation switch 24b are determined to have exceeded a predetermined threshold, it is determined that an abnormal winning to the second big winning opening 24c has occurred as a predetermined error.

  As described above, the first start opening switch 14a and the first winning confirmation switch 14b, the second starting opening switch 15a and the second winning confirmation switch 15b, the first count switch 23a, the third winning confirmation switch 23b, and the second count switch 24a. And the fourth winning confirmation switch 24b are configured by sensors of different detection methods (in this example, a proximity switch and a photo sensor), for example, using the electromagnetic wave or the like, the first start winning award 13a, When a fraudulent action is performed to make the recognition so that the number of winnings at the start winning port 13b, the first grand winning port 23c, and the second large winning port 24c is larger than the actual winning number, the proximity switch is used. There is a difference between the number of game balls detected and the number of game balls detected by the photoswitch, and the game control microcomputer 156 determines that the difference ball number is a predetermined threshold value. (E.g., 15 in this embodiment) for determining that abnormal winning if it exceeds occurs, it is possible to take reliable fraud measures.

  Decorative members 25L and 25R having decorative LEDs 25a blinking and displayed during the game are provided around the left and right sides of the game area 7, and an out port 26 for absorbing a game ball that has not won a prize is provided below. 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 lamp 28a, a left frame lamp 28b, and a right frame lamp 28c are provided. The top frame lamp 28a, the left frame lamp 28b, the right frame lamp 28c, and the decoration LED 25a are examples of a decoration light emitter provided in the gaming machine.

  Further, a center frame ornament 11 (halftone dot region in FIG. 1) for decorating the periphery of the display screen is provided around the effect display device 9, and the second frame described above is provided above the center frame ornament 11. A special variable winning ball apparatus 24 is provided, and center frame decoration LEDs 62 a to 62 d (see FIG. 3) that emit light to the end face of the light guide plate 351 are provided.

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

  A game ball launched from the hitting ball launching device 65 (see FIG. 2) by the player's operation enters the game area 7 through the 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 (stop symbol) at the time of stop will be different from the big hit symbol (predetermined display result) Is “small hit”, and if the special symbol at the time of stoppage (stop symbol) is stopped and displayed, a special symbol different from the big hit symbol and the small hit symbol is “lost”.

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

  In this embodiment, when the big win symbol corresponding to “non-probability change” or “probability change A” in the special figure game is stopped and displayed, the first big win state (15 rounds) as the multi-round specific game state is displayed. (Big hit state). In the big hit gaming state (usually 15 round big hit state), the first big winning opening 23c of the first special variable winning ball apparatus 23 is set to a predetermined period (for example, 29.5 seconds) or a predetermined number (for example, eight). ), The first special variable winning ball apparatus 23 is changed to the first state (open state) advantageous to the player, so that the round is executed. In this way, the first special variable winning ball apparatus 23 that opens the first big winning opening 23c during the round receives the game ball falling on the surface of the game board 6, and then closes the first big winning opening 23c. By setting the state, the first special variable winning ball apparatus 23 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the 15 round big hit state, the number of executions of the round which is the opening cycle of the first big winning opening 23c becomes the first round number (for example, “15”). A game in the 15 round big hit state in which the number of round executions is “15” is also referred to as a 15-time open game. In such a 15 round big hit state, every time a game ball wins the first big winning opening 23c, 15 balls (prize balls) are obtained. The 15-round big hit state is also referred to as a first specific game state.

  When the big hit symbol corresponding to “probability change B” is stopped and displayed as the confirmed special symbol in the special figure game, the state shifts to the second big hit state (high-speed 15 round big hit state) as the multi-round specific gaming state. In the second big hit state, the second special winning opening 24c of the second special variable winning ball device 24 is set to a second period (for example, 0.5 seconds) shorter than the first period in the first big hit state or a predetermined number (for example, 3). A round in which the second special variable winning ball apparatus 24 is changed to the first state (open state) advantageous to the player is executed by setting the open state in the period until the number of winning balls is generated. In this way, the second special variable winning ball device 24 that has opened the second big prize opening 24c during 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 24c. By setting the state, the second special variable winning ball apparatus 24 is changed to the second state (closed state) disadvantageous to the player, and one round is completed. In the second big hit state, the number of executions of the round which is the opening cycle of the second big winning opening 24c is the second round number (for example, “15”).

  In such a second big hit state, 15 game balls (prize balls) are obtained if a game ball wins the second big winning opening 24c, but the opening period of the second big winning opening 24c is the second period ( 0.5 seconds) and very short. For this reason, the second big hit state is a big hit gaming state in which a ball (prize ball) cannot be obtained substantially. The second big hit state is also called a second specific game state. Further, the second big hit state may be one in which the number of round executions is smaller than that in the first big hit state. That is, in the second big hit state, the period in which the second big prize opening 24c is changed to the open state in each round is a second period shorter than the first period in the first big hit state, and the number of executions of the round is the first. It may be at least one of the second round numbers less than the first round number in the big hit state.

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

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

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

  After the special symbol corresponding to “small hit” is stopped and displayed as the confirmed special symbol in the special symbol game, the small hit game state is controlled. In this small hit game state, similarly to the second big hit state, in the second special variable winning ball apparatus 24, a variable winning operation for changing the second big winning port 24c to the first state (open state) advantageous to the player is performed. Is called. That is, in the small hit gaming state, for example, the operation of setting the second special variable winning ball device 24 to the first state (open state) for the second period is the second number {the number of executions equal to the second number of rounds (in this example, , 15 times)}. In the small hit gaming state, as in the second big hit state, the period during which the second special variable winning ball device 24 is in the first state is the second period, and the number of executions of the operation in the first state is Control may be made so that at least one of the second times is performed. After the small hit gaming state ends, the gaming state is not changed, and the game state before the variable display result becomes “small hit” is continuously controlled. However, if the number of executions of the special figure game in the special gaming state has reached the predetermined number when the special figure game with the variable display result “small hit” is executed, after the end of the small hit gaming state, The special gaming state may end and return to the normal state. A game in the small hit game state in which the number of times that the second special variable winning ball apparatus 24 is set to the first state by the variable winning operation is “15” is also referred to as a 15-time open game, similar to the game in the second big win state. The When the winning ball device provided separately from the second special variable winning ball device 24 in each round in the second big hit state is changed to the first state, even in the small hit gaming state, the second big hit state is changed. In the same manner, the winning ball apparatus may be changed to the first state.

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

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

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

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

  In the “left”, “middle”, and “right” decorative symbol display areas provided in the effect display device 9, the special symbol game using the first special symbol and the second special symbol in the first special symbol display 8a. Corresponding to the start of one of the special figure games using the second special figure on the display unit 8b, the variable display (variation display) of the decorative symbols is started. In the period from the start of variable display of decorative symbols to the end of variable display due to the stop display of the fixed decorative symbols in the “left”, “middle”, and “right” decorative symbol display areas, The variable display state may be a predetermined reach state. Here, the reach state means a decorative symbol (“reach” which is not yet temporarily stopped when the decorative symbol temporarily stopped displayed in the display area of the effect display device 9 forms a part of the jackpot combination. "Varying symbol") 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 fluctuating, 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.

  Each control board is equipped with control means including a control microcomputer. The control means is an electrical component (game device: ball payout device 97, effect display device 9, light emission from a lamp, LED, etc.) provided in the gaming machine according to a command signal (control signal) as a command from the game control means or the like. Body, speaker 27, etc.). Hereinafter, the main board 31 may be included in the control board for explanation. In that case, the control means mounted on the control board refers to each of the game control means and the means for controlling the electrical components provided in the gaming machine in accordance with a command signal from the game control means or the like. A substrate on which a microcomputer other than the main substrate 31 is mounted may be referred to as a sub-substrate. The ball payout device 97 is a device for paying out a game ball guided by a passage for guiding a game ball and a sprocket driven by a stepping motor or the like to an upper plate or a lower plate. A payout number counting switch for counting prize balls and rental balls is also configured as part of the unit. In this embodiment, the payout detection means is realized by a payout number count switch, and has a function of detecting that a winning ball or a lending ball is actually paid out from the ball payout device 97. In this case, the payout number count switch outputs a detection signal every time one payout of prize balls or rental balls is detected.

  On the back surface of the pachinko gaming machine 1, a terminal board 91 having terminals for outputting various information to the outside of the pachinko gaming machine 1 is installed. The terminal board 91 includes, for example, information output signals such as jackpot information indicating the occurrence of a jackpot gaming state (start signal, symbol determination frequency 1 signal, jackpot 1 signal, jackpot 2 signal, jackpot 3 signal, time reduction signal, security An information output terminal for externally outputting signals, prize ball signals 1, gaming machine error status signals) is provided.

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

  When a large number of game balls as prizes based on winning a prize or a game ball based on a ball lending request are paid out and the hitting ball supply tray 3 is full, the game balls are guided to the surplus ball receiving tray 4 through the surplus ball guiding path. Further, when the game ball is paid out, a sensing lever (not shown) presses a full tank switch (not shown) as the storage state detection means, and the full tank switch as the storage state detection means is turned on. In this state, the rotation of the payout motor in the ball payout device is stopped, the operation of the ball payout device is stopped, and the driving of the ball hitting device 65 is also stopped.

  FIG. 3 is a block diagram showing an example of the circuit configuration of the main board (game control board) 31. FIG. 3 also shows a payout control board 37, an effect control board 80, and the like. A game control microcomputer (corresponding to game control means) 156 for controlling the pachinko gaming machine 1 according to a program is mounted on the main board 31. The game control microcomputer 156 includes a ROM 54 for storing a game control (game progress control) program and the like, a RAM 55 as storage means used as a work memory, a CPU 56 for performing control operations in accordance with the program, and an I / O port unit 57. including. In this embodiment, the ROM 54 and the RAM 55 are built in the game control microcomputer 156. That is, the game control microcomputer 156 is a one-chip microcomputer. The one-chip microcomputer only needs to include at least the RAM 55, and the ROM 54 may be external or internal. The I / O port unit 57 may be externally attached. The game control microcomputer 156 further incorporates a random number circuit 153 that generates hardware random numbers (random numbers generated by the hardware circuit).

  In the game control microcomputer 156, the CPU 56 executes control in accordance with the program stored in the ROM 54, so that the game control microcomputer 156 (or CPU 56) executes (or performs processing) hereinafter. Specifically, the CPU 56 executes control according to a program. The same applies to microcomputers mounted on substrates other than the main substrate 31.

  The game control microcomputer 156 has a built-in random number circuit 153. The random number circuit 153 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 153 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 153 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 153 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 153 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 153. 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 an initial value of the numerical data updated by the random number circuit 153. By performing such processing, the randomness of the random number generated by the random number circuit 153 can be further improved.

  The game control microcomputer 156 reads the numerical data as random R from the random number circuit 153 when a start winning to the first start port switch 14a or the second start port switch 15a occurs, and starts to change the special symbol and 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 155 is incorporated. The payout control microcomputer and the effect control microcomputer also have a serial communication circuit (not shown) for inputting / outputting signals with the game control microcomputer 156 through serial communication.

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

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

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

  Bits 0 to 7 of the input port 0 include a power-off signal and clear switch from the power supply board, a gate switch 32a, winning port switches 30a and 30b, a magnet sensor signal 1, a magnet sensor signal 2, a door opening signal, and a prize, respectively. Sphere information is input. In addition, two magnetic sensors G (see FIG. 31) for detecting fraud using a magnet are provided in the bits 4 and 5 of the input port 0, and detection signals from the respective magnet sensors are also input ports. Input from 0. Also, the detection signal of the first start port switch 14a is input to bit 0 of the input port 1, and the detection signal of the first winning confirmation switch 14b is input to bit 1 of the input port 1, The detection signal of the second start opening switch 15a is input to bit 2, the detection signal of the second winning confirmation switch 15b is input to bit 3 of the input port 1, and the detection signal of the second winning confirmation switch 15b is input to bit 4 of the input port 1. The detection signal of the first count switch 23a is input, the detection signal of the third winning confirmation switch 23b is input to bit 5 of the input port 1, and the detection signal of the second counter switch 24a is input to bit 6 of the input port 1. Is entered. The detection signal of the fourth winning confirmation switch 24b is input to bit 7 of the input port 1.

  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 21 that opens and closes the first special variable winning ball device 23, a solenoid 22 that opens and closes the second special variable winning ball device 24, 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 circuit for resetting game control microcomputer 156 An information output circuit 64 that outputs information output signals such as jackpot information indicating the occurrence of a jackpot gaming state to an external device such as a hall computer via the terminal board 91 is also mounted on the main board 31. Has been.

  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 sends drive signals to the top frame LED 28a, left frame LED 28b, right frame LED 28c, center frame decoration LEDs 62a to 62d, accessory LED 63, first light guide plate LEDs 60a to 60t and second light guide plate LEDs 61a to 61f, which will be described later. It supplies to each LED provided in the side. 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. 7 is a flowchart showing main processing executed by the game control microcomputer 156 on the main board 31. When power is supplied to the gaming machine and power supply is started, the input level of the reset terminal to which the reset signal is input becomes high level, and the gaming control microcomputer 156 (specifically, the CPU 56) After executing a security check process, which is a process for confirming whether the contents of the program are valid, the main process after step S1 is started. In the main process, the CPU 56 first performs necessary initial settings.

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

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

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

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

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

  The CPU 56 determines whether or not the probability change flag is set among the data indicating the gaming state before the power supply is stopped. When the probability change flag is set, the CPU 56 turns on the high probability notification LED 24. Therefore, a high-accuracy notification flag setting process for setting a high-accuracy notification flag is performed (step S42 +).

  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 the present 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 step S43.

  In this embodiment, it is confirmed whether the data in the backup RAM area is stored using both the backup flag and the check data. However, 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 153 (step S14). For example, the CPU 56 performs setting according to the random number circuit setting program to cause the random number circuit 153 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 a stop symbol of a 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 (normal symbol determination random number generation counter). 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 the present embodiment, the reach effect is executed using an effect symbol (effect symbol) that is 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, via the input driver circuit 58, 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 The detection signals of the winning confirmation switch 23b, the second count switch 24a, the fourth winning confirmation switch 24b, and the respective winning opening switches 30a and 30b are inputted, 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 and the high-accuracy notification LED 24 is executed (step S22). About the 1st special symbol display 8a, the 2nd special symbol display 8b, and the normal symbol display 10, a drive signal is output with respect to each display according to the content of the output buffer set by step S32, S33. Execute control.

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

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

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

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

  Further, the CPU 56 performs an information output process for outputting data such as jackpot information, starting information, probability variation information, startup accuracy information supplied to the hall management computer, for example (step S29). Note that the startup high-accuracy information is output from the information output circuit 53 to a call lamp (not shown) provided above the pachinko gaming machine 1 in response to the high-accuracy notification flag being set.

  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, and the count switch 23 (step S30). Specifically, the payout control micro board mounted on the payout control board 37 in response to winning detection based on any one of the first start port switch 14a, the second start port switch 15a and the count switch 23 being turned on. A payout control command (prize ball number signal) indicating the number of prize balls is output to the computer. The payout control microcomputer drives the ball payout device 97 in accordance with a payout control command indicating the number of winning balls.

  In this embodiment, a RAM area (output port buffer) corresponding to the output state of the output port is provided. However, the CPU 56 relates to the 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 change speed is 1 frame / 0.2 seconds until the end flag is set when the start flag set in the special symbol process is set, the CPU 56, for example, every 0.2 seconds passes. Then, the value of the display control data set in the output buffer is incremented by one. Further, the CPU 56 outputs a drive signal in step S22 in accordance with the display control data set in the output buffer, whereby the first special symbol display unit 8a and the second special symbol display unit 8b Variable display of the second special symbol is executed.

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

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

  With the above control, in this embodiment, the game control process is started every 2 ms. The game control process corresponds to the process of 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.

  When the shifted symbol is stopped and displayed on the first special symbol display 8a or the second special symbol display 8b and the effect display device 9, the variable display state of the effect symbol is started after the variable display of the effect symbol is started. There may be a case where a predetermined combination of effect symbols that does not reach reach is stopped and displayed without reaching the reach state. Such a variable display mode of the effect symbol is referred to as a variable display mode of “non-reach” (also referred to as “normally shift”) in a case where the variable display result is a loss symbol.

  When the shifted symbol is stopped and displayed on the first special symbol display 8a or the second special symbol display 8b and the effect display device 9, the variable display state of the effect symbol is changed after the variable display of the effect symbol is started. After reaching the reach state, a reach effect is executed, and a combination of predetermined effect symbols that do not eventually become a jackpot symbol may be stopped and displayed. Such a variable display result of the effect design is referred to as a variable display mode of “reach” (also referred to as “reach out”) when the variable display result is “out of”.

  In this embodiment, when the big hit symbol is stopped and displayed on the first special symbol display 8a or the second special symbol display 8b, the reach effect is executed after the variable display state of the effect symbol becomes the reach state. Finally, the effect symbols are all stopped and displayed in the “left”, “middle”, and “right” symbol display areas of the effect display device 9.

  Next, the switch process (step S21) in the timer interrupt process will be described. In this embodiment, when the ON state of the detection signal of each switch related to winning detection or gate passage continues for a predetermined time, it is determined that the switch has been turned on, and processing corresponding to the switch on is started. In each 2-byte buffer formed in the RAM 55, the previous port buffer is a buffer in which the previous switch-on / off determination result (for example, 4 ms before) is stored. The port buffer is a buffer for storing the contents of the ports 0 and 1 input this time. The switch-on buffer is a buffer in which the corresponding bit is set to 1 when switch on is detected and the corresponding bit is set to 0 when switch off is detected. The previous port buffer, port buffer, and switch-on buffer are prepared for each of the input ports 0 and 1. For example, in this embodiment, two switch-on buffers 1 and 2 are prepared, the switch state of the input port 0 is set to the switch-on buffer 1, and the switch state of the input port 1 is set to the switch-on buffer 2. Is set.

  FIG. 9 is a flowchart showing a processing example of the switch processing in step S21 in the game control processing. In the switch process, the game control microcomputer 156 first inputs the data input to the input ports 0 and 1 (step S101), and sets the input data in the port buffer (step S102).

  Next, the initial value of the weight counter formed in the RAM 55 is set (step S103), and the value of the weight counter is decremented by 1 until the value of the weight counter becomes 0 (steps S104 and S105).

  When the value of the wait counter reaches 0, the data of the input ports 0 and 1 are input again (step S106), and a logical product is obtained for each bit between the input data and the data set in the port buffer. (Step S107). Then, the logical product operation result is set in the port buffer (step S108). Of the two input data input from the input port 0 with a time interval of approximately [initial value of weight counter × (processing time of steps S104, S105)] by the processing of steps S103 to S108, both “ Only the bits that are “1” will be “1” in the port buffer. In other words, if the ON state of the switch detection signal continues for a predetermined period [initial value of wait counter × (processing time of steps S104 and S105)], the corresponding bit in the port buffer becomes “1”.

  Further, the game control microcomputer 156 performs exclusive OR for each bit between the data previously set in the port buffer and the data set in the port buffer (step S109). In the result of the exclusive OR operation, the bit corresponding to the switch for which the previous switch-on / off determination result (for example, 4 ms before) differs from the switch-on / off determination result determined to be on this time is “ 1 ”. The game control microcomputer 156 further performs a logical product for each bit between the operation result of the exclusive OR and the data set in the port buffer (step S110). As a result, of the bits corresponding to the switches for which the previous switch on / off determination result and the switch on / off determination result determined to be on this time are different (according to the exclusive OR operation result), the current on Only the bit corresponding to the switch determined to be (by AND operation) remains as “1”.

  Then, the game control microcomputer 156 sets the logical product calculation result in step S110 in the switch-on buffer (step S111), and sets the contents of the port buffer in which the calculation result in step S108 is set in the previous port buffer. (Step S112).

  By the above processing, among the switches that have been on for a predetermined period of time, the switch on / off determination result of the previous time (for example, 4 ms ago) was off, that is, the switch changed from the off state to the on state. The bit corresponding to the switch is “1” in the switch-on buffer.

  Further, the game control microcomputer 156 (specifically, the CPU 56) performs switch normality / abnormality check processing (step S113).

  FIG. 10 is a flowchart showing the switch normal / abnormal check process. In the switch normal / abnormal check process shown in FIG. 10, the CPU 56 reads the contents of the switch-on buffer corresponding to the input port 1 (step S121). Then, it is confirmed whether or not the value of bit 0 corresponding to the first start port switch 14a in the switch-on buffer corresponding to the input port 1 is 0 (step S122). That is, it is confirmed whether or not the first start port switch 14a (proximity switch) provided in the first winning path of the first start winning port 13a is turned on (detects a game ball).

  When the value of bit 0 corresponding to the first start port switch 14a in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the first start port switch 14a is in the ON state), it is formed in the RAM 55. The value of the switch counter being incremented is incremented by 1 (step S123).

  Further, the CPU 56 checks whether or not the value of bit 1 corresponding to the first winning confirmation switch 14b in the switch-on buffer corresponding to the input port 1 is 0 (step S124). That is, it is confirmed whether or not the first winning confirmation switch 14b (photo sensor) provided in the first winning passage of the first start winning opening 13a is turned on (the game ball is detected).

  When the value of bit 1 corresponding to the first winning confirmation switch 14b in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the first winning confirmation switch 14b is in the ON state), it is formed in the RAM 55. The value of the switch counter is decreased by 1 (step S125).

  Further, the CPU 56 checks whether or not the value of bit 2 corresponding to the second start port switch 15a in the switch-on buffer corresponding to the input port 1 is 0 (step S126). That is, it is confirmed whether or not the second start port switch 15a (proximity switch) provided in the second winning path of the second start winning port 13b is turned on (detects a game ball).

  When the value of bit 2 corresponding to the second start port switch 15a in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the second start port switch 15a is in the ON state), it is formed in the RAM 55. The value of the switch counter being incremented is incremented by 1 (step S127).

  Further, the CPU 56 checks whether or not the value of bit 3 corresponding to the second winning confirmation switch 15b in the switch-on buffer corresponding to the input port 1 is 0 (step S128). That is, it is confirmed whether or not the second winning confirmation switch 15b (photo sensor) provided in the second winning passage of the second start winning opening 13b is turned on (the game ball is detected).

  When the value of bit 3 corresponding to the second winning confirmation switch 15b in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the second winning confirmation switch 15b is in the ON state), it is formed in the RAM 55. The value of the switch counter is decreased by 1 (step S129).

  Further, the CPU 56 checks whether or not the value of bit 4 corresponding to the first count switch 23a in the switch-on buffer corresponding to the input port 1 is 0 (step S130). That is, it is confirmed whether or not the first count switch 23a (proximity switch) provided in the first big winning path of the first big winning opening 23c is turned on (game ball is detected).

  When the value of bit 4 corresponding to the first count switch 23a in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the first count switch 23a is in the ON state), the bit is formed in the RAM 55. The value of the switch counter is incremented by 1 (step S131).

  Further, the CPU 56 confirms whether or not the value of bit 5 corresponding to the third winning confirmation switch 23b in the switch-on buffer corresponding to the input port 1 is 0 (step S132). That is, it is confirmed whether or not the third winning confirmation switch 23b (photo sensor) provided in the first large winning passage of the first large winning opening 23c is turned on (detects a game ball).

  When the value of bit 5 corresponding to the third winning confirmation switch 23b in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the third winning confirmation switch 23b is in the ON state), it is formed in the RAM 55. The value of the switch counter that has been set is decremented by 1 (step S133).

  Further, the CPU 56 checks whether or not the value of the bit 6 corresponding to the second count switch 24a in the switch-on buffer corresponding to the input port 1 is 0 (step S134). That is, it is confirmed whether or not the second count switch 24a (proximity switch) provided in the second big winning path of the second big winning opening 24c is turned on (detects a game ball).

  When the value of bit 6 corresponding to the second count switch 24a in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the second count switch 24a is in the ON state), it is formed in the RAM 55. The value of the switch counter is incremented by 1 (step S135).

  Further, the CPU 56 confirms whether or not the value of the bit 7 corresponding to the fourth winning confirmation switch 24b in the switch-on buffer corresponding to the input port 1 is 0 (step S136). That is, it is confirmed whether or not the fourth winning confirmation switch 24b (photo sensor) provided in the second large winning path of the second large winning opening 24c is turned on (the game ball is detected).

  When the value of bit 7 corresponding to the fourth winning confirmation switch 24b in the switch-on buffer corresponding to the input port 1 is 0 (that is, when the fourth winning confirmation switch 24b is in the ON state), it is formed in the RAM 55. The value of the switch counter that has been set is decremented by 1 (step S137).

  Then, the CPU 56 checks whether or not the value of the switch counter is equal to or greater than a predetermined value (step S138). When the value of the switch counter is equal to or greater than the predetermined value, the CPU 56 selects any one of the first start winning opening 13a, the second starting winning opening 13b, the first large winning opening 23c, and the second large winning opening 24c. It is determined that an abnormal winning has occurred, and a predetermined time (in this example, 4 minutes) is set in the security signal information timer (step S139). In this embodiment, the CPU 56 sets a predetermined time (4 minutes in this example) to the security signal information timer based on the fact that the value of the switch counter has become 15 or more as a predetermined value. . In the present embodiment, the information output process (see S31) is executed based on the fact that the predetermined time is set in the security signal information timer in step S139, whereby the first start winning opening 13a and the second starting winning opening are obtained. 13b, when an abnormal winning is detected at the first and second major winning openings 23c, 24c, a security signal is externally output for a predetermined time (in this example, 4 minutes).

  In the process of step S138, the CPU 56, for example, based on the fact that the value of the switch counter becomes 10 or more, the first start winning port 13a, the second starting winning port 13b, the first big winning port 23c, In addition to determining that the abnormal winning at the second big winning opening 24c has occurred, conversely, the first start winning opening 13a and the second starting position are also determined based on the fact that the value of the switch counter becomes -10 or less. You may make it determine with the abnormal winning to the start winning opening 13b, the 1st big winning opening 23c, and the 2nd big winning opening 24c having generate | occur | produced. In this case, if the switch counter value is configured so that it cannot be recognized that the value is negative, for example, 10 is set as the default value of the switch counter value. Based on the counter value becoming 0 or 20 or more, abnormal winning occurs at the first starting winning port 13a, the second starting winning port 13b, the first major winning port 23c, and the second major winning port 24c. You may make it determine with having carried out.

  In this embodiment, even when a value is already set in the security signal information timer and the security signal is being output to the outside, when a new abnormal winning is detected, the process of step S127 is executed again, A predetermined time (4 minutes in this example) is overwritten in the signal information timer. Therefore, when a new abnormal winning is detected during the external output of the security signal, the external output period of the security signal is substantially extended, and a predetermined time (in this example) from the time when the new abnormal winning is detected. 4 minutes) The output of the security signal is continued.

  In this embodiment, only one switch counter is used to detect abnormal winning at the first start winning opening 13a, the second starting winning opening 13b, the first big winning opening 23c, and the second big winning opening 24c. As shown, the number of detections of the first start opening switch 14a and the number of detections of the first winning confirmation switch 14b or the number of detections of the second starting opening switch 15a and the number of detections of the second winning confirmation switch 15b or the first count switch Different switch counters may be used for the number of detections 23a and the number of detections of the third winning confirmation switch 23b or the number of detections of the second count switch 23b and the number of detections of the fourth winning confirmation switch 24b. In this case, for example, the value of the first switch counter is incremented by 1 each time the on state of the first start port switch 14a is detected, and every time the on state of the first winning confirmation switch 14b is detected. What is necessary is just to add 1 to the value of the counter for two switches. In step S138, based on the determination that the difference between the value of the first switch counter and the value of the second switch counter is equal to or greater than a predetermined value (for example, 15), the first start winning award 13a is entered. It may be determined that an abnormal winning has occurred and the process of step S139 is executed to output the security signal to the outside.

  If it is detected that an abnormal winning at the first start winning opening 13a has occurred, the process of step S139 is executed to output a security signal to the outside, and a predetermined error notification command is sent to the effect control microcomputer. It is desirable that error notification can be performed by displaying a predetermined error screen on the effect display device 9 on the effect control microcomputer side.

  Further, for example, in addition to the abnormal winning at the first start winning opening 13a, the security signal is also detected when an abnormal winning at the other winning openings 29a, 29b, an abnormal magnetic error, an abnormal radio wave error, or a communication error is detected. When configured to output, a different error notification command for each type of error may be transmitted to the production control microcomputer. Then, on the effect control microcomputer side, error notification may be performed by causing the effect display device 9 to display different error screens for each type of error.

  In the above configuration, when the power supply is resumed after the power supply to the gaming machine is stopped, an error notification is being made before the power supply is stopped. The error notification command may be transmitted again to the effect control microcomputer. That is, since the storage contents such as RAM are not backed up by the backup power source on the production control microcomputer side, if a power failure occurs, it is not possible to execute the production such as error notification that has been executed until then. However, the error notification can be resumed when the power failure is recovered by configuring the predetermined error notification command to be transmitted again when the power failure is recovered. The game control microcomputer 156 also backs up the value of the security signal information timer to the backup RAM, and if the security signal is being output before the power supply is stopped, it is backed up when the power failure is restored. The output of the security signal may be resumed based on the value of the security signal information timer. By providing these configurations, it is possible to prevent an illegal act such as turning off the error notification or stopping the output of the security signal by intentionally turning off the power to the gaming machine.

  Further, when a game ball is detected by the first start port switch 14a (proximity switch) corresponding to the bit 0, it becomes “0”. The bit 1 of the switch-on buffer corresponding to the input port 1 becomes “0” when a game ball is detected by the first winning confirmation switch 14 b (photo sensor) corresponding to the bit 1. If the switch is operating normally and has not received any fraudulent activity (an act of illegally turning on a detection signal from the switch or illegally turning on an on-state detection signal), the first Since the start opening switch 14a is disposed upstream of the first winning confirmation switch 14b, the first starting opening switch 14a (proximity switch) is first turned on, and then the first winning confirmation switch 14b (photo sensor). ) Should turn on. Accordingly, the value of the switch counter is first incremented to 1 based on the first start port switch 14a being turned on (see step S123), and then the switch is based on the first winning confirmation switch 14b being turned on. The counter value is decremented by 1 and returned to 0 (see step S125). Therefore, when the game ball passes through the switch, both the bit 0 and the bit 1 of the switch-on buffer corresponding to the input port 1 become “0”, and if it is in a normal operation state, the timing is shifted to the count-up timing ( The value of the switch counter should be kept at 0, although this corresponds to a shift in the passing timing of game balls).

  However, when a fraudulent act is performed by radio waves, the off-state is illegally interrupted by radio waves during the period when the first start port switch 14a is turned on once, and the first start port switch 14a is turned twice by the radio wave. There is a risk of fraudulent acts that make it appear as if it was turned on. Therefore, although the first start port switch 14a is turned on only once, it is misrecognized that the first start port switch 14a is turned on twice, and the value of the switch counter is 2 in total. It is added to 2 (step S123 is executed twice). On the other hand, the first winning confirmation switch 14b arranged on the downstream side is different in detection method from the electromagnetic first start port switch 14a, and uses an optical photosensor. Unaffected by actions. Therefore, when one game ball is detected by the first start opening switch 14a and the game ball is detected on the first winning confirmation switch 14b side after a short delay, the first winning confirmation switch 14b is normally turned on. This is detected only once, and the value of the switch counter is decremented by 1 to 1 (see step S125). Therefore, when a fraudulent act by radio waves is performed, there is a difference in the number of detections between the first start switch 14a and the first winning confirmation switch 14b having different detection methods. Is not maintained at 0 and the value of the switch counter is equal to or greater than a predetermined value (15 in this example) (the detection error between the first start port switch 14a and the first winning confirmation switch 14b is Based on the fact that the accumulated value is equal to or greater than a predetermined value (15 in this example), it is possible to detect that an abnormal winning to the first start winning opening 13a has occurred.

  Here, an example is shown in which an abnormal winning to the first starting winning opening 13a is detected based on the detection result of the first starting opening switch 14a and the detection result of the first winning confirmation switch 14b. Based on the detection result of the switch 15a and the detection result of the second winning confirmation switch 15b, it is possible to detect an abnormal winning to the second start winning opening 13b. In addition, an abnormal prize is awarded to the first and second big prize openings 23b and 24b based on the detection results of the first and second count switches 23a and 24a and the detection results of the third and fourth prize confirmation switches 23b and 24b. Can be detected.

  In addition, it is also conceivable that a similar illegal act is performed by an act of illegally irradiating light. In this case, during the period when the first winning confirmation switch 14b is turned on once, an illegal act that causes the off state to be illegally interrupted by light and to recognize that the first winning confirmation switch 14b is turned on twice. May be done. However, in this case, on the contrary, since the electromagnetic first start port switch 14a side can normally detect the game ball without being affected by the illegal act of light, the value of the switch counter is kept at 0 similarly. The cumulative value of the detection error between the first start port switch 14a and the first winning confirmation switch 14b is a predetermined value based on the fact that the value of the switch counter is not less than a predetermined value (15 in this example). It is possible to detect that an abnormal winning to the first start winning opening 13a has occurred (based on (in this example, 15) or more).

  In this embodiment, the output of the first start opening switch 14a and the first winning confirmation switch 14b is negative logic, but the output of the first starting opening switch 14a and the first winning confirmation switch 14b is You may comprise so that it may become positive logic. In this case, for example, the output levels of the first start port switch 14a and the first winning confirmation switch 14b are logically inverted by the input driver circuit and then input to the game control microcomputer 156.

  Further, in this embodiment, the value of the switch counter is not kept at 0 (a detection error has occurred between the first start port switch 14a and the first winning confirmation switch 14b), and an abnormality is immediately caused. Rather than determining that a prize has been won, it is determined that an abnormal prize has occurred based on the value of the switch counter being equal to or greater than a predetermined value (15 in this example). Such a configuration prevents, for example, a case where a game ball has become clogged in the first start winning opening 13a from being determined as an abnormal winning due to an illegal act.

  Next, as shown in FIG. 6A, in the first winning path, the first start port switch 14a and the first winning confirmation switch 14b are arranged at a certain distance in the vertical direction. Therefore, the game ball won in the first start winning opening 13a is first detected by the first start opening switch 14a, and then detected by the first winning check switch 14b on the downstream side after a while. Therefore, when the game ball is clogged in the first winning path, there is a difference in the number of detections due to the physical distance difference between the first start port switch 14a and the first winning confirmation switch 14b. It becomes the state. In the first winning path, a maximum of nine detection errors occur between the first start port switch 14a and the first winning confirmation switch 14b.

  As shown in FIG. 6B, in the second winning path, the second start opening switch 15a and the second winning confirmation switch 15b are arranged at a certain distance in the vertical direction. Therefore, the game ball won in the second start winning opening 13b is first detected by the second start opening switch 15a, and then detected by the second winning check switch 15b on the downstream side after a while. Therefore, when the game ball is clogged in the second winning aisle, a difference occurs in the number of detections due to the physical distance difference between the second start opening switch 15a and the second winning confirmation switch 15b. It becomes the state. In the second winning path, a maximum of two detection errors occur between the second start port switch 15a and the second winning confirmation switch 15b.

  As shown in FIG. 6C, the first count switch 23a and the third winning confirmation switch 23b are arranged at a certain distance from side to side and front and rear in the first big prize passage. Therefore, the game ball that has won the first big winning opening 23c is first detected by the first count switch 23a, and then detected by the third winning confirmation switch 23b on the downstream side after a while. Therefore, when the game ball is clogged in the first big winning path, a difference occurs in the number of detections due to a physical distance difference between the first count switch 23a and the third winning confirmation switch 23b. It becomes the state. It is assumed that a maximum of four detection errors occur between the first count switch 23a and the third winning confirmation switch 23b in the first big winning path.

  As shown in FIG. 6 (d), the second count switch 24a and the fourth winning confirmation switch 24b are arranged at a certain distance from side to side and front and rear in the second big prize passage. Therefore, the game ball won in the second big winning opening 24c is first detected by the second count switch 24a, and then detected by the fourth winning confirmation switch 24b on the downstream side after a while. Therefore, when the game ball is clogged in the second big prize passage, a difference occurs in the number of detections due to the physical distance difference between the second count switch 24a and the fourth prize confirmation switch 24b. It becomes the state. It is assumed that a maximum of four detection errors occur between the second count switch 24a and the fourth winning confirmation switch 24b in the second big winning path.

  In the present embodiment, the value of the switch counter is an upstream proximity switch (14a, 14a, a second winning path, a first winning path, a first winning path, a second winning path) of a plurality of winning paths. 15a, 23a, 24a) and the first start port in a ball clogged state in the first winning path which is the winning path having the largest physical distance difference between the downstream photosensors (14b, 15b, 23b, 24b). By determining that an abnormal winning has occurred based on the fact that the detection error between the switch 14a and the first winning confirmation switch 14b is greater than or equal to a predetermined value (15 in this example) with a sufficient margin. , Preventing a game ball from being judged as an abnormal prize due to an illegal act in any of the first prize path, the second prize path, the first grand prize path, and the second major prize path. Have .

  In the present embodiment, the predetermined detection value (15 in this example) is greater than or equal to nine detection errors between the first start port switch 14a and the first winning confirmation switch 14b in the ball clogged state. Although the case where it is determined that an abnormal winning has occurred based on the above is shown, the predetermined value used for determining the abnormal winning is not limited to that shown in the present embodiment. For example, it is possible to prevent erroneous determination of an abnormal winning if the number is more than nine detection errors between the first start opening switch 14a and the first winning confirmation switch 14b in a ball jammed state. Alternatively, it may be determined that an abnormal winning has occurred based on the value of the switch counter being 10 or more.

  In addition, when the detection errors in the ball clogged state in a plurality of winning paths are the same number (for example, 3), the detection error has become a predetermined value (for example, 10) or more with a sufficient margin for the three detection errors. Based on the above, it may be determined that an abnormal winning has occurred.

  In addition, when it is configured to be able to detect abnormal winnings in a plurality of winning aisles, there are more than the total number of detection errors (9 + 2 + 4 = 15) in the ball clogged state in all these winning aisles. If the abnormal winning is determined by using the number (for example, 20) as the predetermined value, it is possible to prevent the abnormal winning from being erroneously determined.

  In the present embodiment, the detection error in the ball clogged state in the plurality of winning paths can be detected by one switch counter, so that no switching counter corresponding to each winning path is provided. However, it was possible to detect abnormal winnings in each winning path, but provided a switch counter corresponding to each winning path, set a predetermined value corresponding to the detection error for each winning path, The detection error in the switch counter may be monitored to determine whether or not there is an abnormal prize. By doing in this way, it becomes possible to specify in which winning path the winning abnormality has occurred.

  In the present embodiment, the game balls won in the first grand prize opening 23c are detected by the first count switch 23a and the third prize confirmation switch 23b, and the game balls won in the second big prize opening 24c are: Although the detection was made by the second count switch 24a and the fourth winning confirmation switch 24b, as described above, the third winning confirmation switch 23b and the fourth winning confirmation switch 24b are used only for the determination of the abnormal winning. Therefore, for example, the opening and closing of the first big prize opening 23c and the second big prize opening 24c is performed in response to the timing detected by the first count switch 23a and the second count switch 24a.

  Here, an example of the opening / closing timing of the special winning opening door 704 in the first special variable winning ball apparatus will be described. FIG. 11 is a diagram illustrating a relationship between the detection timing of the game ball and the opening / closing timing of the door in the first special variable winning ball apparatus.

  As shown in FIG. 11, for example, in a big hit gaming state that has been triggered by the occurrence of a non-probable big hit or a probable change A big hit, the first big win 23c is opened and the first big win is being played. When a game ball enters (wins) the winning opening 23c, the entered game ball is detected by the first count switch 23a and then detected by the third winning confirmation switch 23b. In addition, the game control microcomputer 156 determines that a game ball has won the first big winning opening 23c at the timing detected by the first count switch 23a.

  Therefore, in the present embodiment, the first grand prize opening 23c is kept open for a predetermined period of 29.5 seconds or until a predetermined number of eight winning balls are generated in each round. Therefore, when the 8th game ball is won, that is, when the first count switch 23a detects the 8th game ball, the solenoid 21 is energized as the closing condition is established, and the big winning door Let 704 be a closed state. By doing in this way, the big prize opening door 704 which opens and closes the 1st big prize opening 23c can be closed quickly, determining a prize abnormality by two sensors.

(Prize unit)

  As shown in FIGS. 12 and 13, the winning opening unit 500 constituting the first start winning opening 13 a and the general winning openings 29 a to 29 d is attached to the board surface plate 200 by a metal screw 501 a from the front side. It is mainly comprised from the opening | mouth attachment member 501 and the prize opening | mouth member 502 attached to the front side of the prize opening attachment member 501 by the metal screw 502a inserted from the back side of this prize opening attachment member 501. A decorative seal 503 is attached to the front face of the winning prize opening member 502. In addition, the winning opening attaching member 501 and the winning opening member 502 are plated members that are molded into a predetermined shape with a synthetic resin material and then subjected to a plating process to be described later.

  The winning opening attaching member 501 is formed in a horizontal elliptical shape when viewed from the front, a mounting plate portion 505 having a passage hole 504 through which a game ball can pass in the center, and a peripheral edge of the passage hole 504 on the back surface of the mounting plate portion 505. It is mainly composed of a passage portion 506 extending from a part toward the rear. The attachment plate portion 505 is formed with attachment holes 506a to which the screws 501a are attached on the left and right, and an attachment hole 506b to which the screws 502a are attached. Further, in the vicinity of the mounting hole 506a on the back surface of the mounting plate portion 505, a positioning projection 507a that fits into a positioning hole H2 (see FIG. 13C) formed in the panel plate 200 is projected. In the vicinity of the mounting hole 506b, a positioning hole 507b is formed in which positioning protrusions 531a and 531b projecting from the rear end face of the winning prize opening member 502 are fitted.

  The passage portion 506 has a substantially U-shaped longitudinal section, and is formed with a winning ball guiding groove 509 having a predetermined front and rear width dimension and a right and left width dimension through which a game ball can pass, and an inner bottom portion thereof. In addition, a guide wall 508 having an upper end surface (see FIG. 13B) inclined downward from the passage hole 504 toward the rear is erected in the front-rear direction.

  The winning opening attaching member 501 configured as described above is configured such that the passage portion 506 is fitted from the front side into an attaching hole H1 (see FIGS. 13B and 13C) formed at a predetermined position of the board surface plate 200. When the mounting plate portion 505 is brought into contact with the front surface of the panel plate 200, the mounting position is determined by the positioning protrusion 507a and the positioning hole 507b and can be mounted from the front side by the screw 501a.

  As shown in FIGS. 12 to 15, the winning opening member 502 includes a front plate portion 520 formed in a substantially circular shape when viewed from the front, and an upward direction extending a predetermined length from the rear surface of the front plate portion 520 to the rear. A U-shaped passage portion 521 is mainly configured.

  As shown in FIG. 14, the front plate portion 520 is formed with a horizontal straight portion 522 at the lower peripheral edge portion, and it can be seen that the straight portion 522 is a lower position. In particular, as shown in FIGS. 13B and 13C, a first concave portion 523 having a substantially circular shape in front view is formed on the front surface of the front plate portion 520. A horizontal straight line portion 524 is also formed at the lower peripheral edge portion of the first recess 523 so that the straight line portion 524 is at the lower position.

  The passage portion 521 is formed with a winning ball guiding groove 525 having a substantially U-shaped longitudinal section in the upper part of a cylindrical member whose axis is directed in the front-rear direction. The left-right width dimension and the front-rear width dimension of the upper surface opening of the winning ball guiding groove 525 are slightly larger than the diameter of the game ball, and when integrated with the winning hole mounting member as shown in FIG. A substantially square winning opening (for example, a starting winning opening 13a, winning openings 29a to 29d) is formed. In addition, a guide wall 526 having an upper end surface (see FIG. 13B) inclined downward toward the rear is erected in the front-rear direction at the inner bottom portion of the winning ball guide groove 525 and has entered. The game ball is guided to the back side.

  At the left and right side positions of the winning ball guiding groove 525 on the rear end surface 521a of the passage portion 521, a pair of left and right first molding concave portions 530a and second molding concave portions 530b for making the passage portion 521 hollow are forward. It is formed towards. In addition, a third molding recess 530c is formed in the lower position of the winning ball guiding groove 525, and the first molding recess 530a, the second molding recess 530b, and the third molding recess 530c. Between the two, screw holes 530d into which the screws 502a are screwed are formed in the front-rear direction.

  In addition, positioning projections 531a and 531b that fit into the positioning holes 507b protrude toward the back side at positions corresponding to the first molding recess 530a and the second molding recess 530b on the rear end surface of the passage portion 521. Has been.

  These first to third molding recesses 530a to 530c are so-called sink marks at the time of molding (the resin melts and shrinks in the process of solidifying by cooling, but when the resin melted at the time of molding is cooled and solidified, Cooling of the thick part and its central part is delayed more than that of the surface, but at this time, there is no occurrence of depression (depression) due to internal contraction in which the solidified surface is delayed and solidified. Thus, it is the recessed part for shaping | molding for forming the inside of the channel | path part 521 in hollow shape beforehand.

  The bottom surface (front surface) 523a of the first recess 523 is formed with a first communication hole 535a at a location corresponding to the first molding recess 530a, and a second communication hole at a location corresponding to the second molding recess 530b. 535b is formed, and third communication holes 535a are formed at locations corresponding to the third molding recesses 530c, and these first to third communication holes 535a to 535c are respectively corresponding to the first to third molding recesses 530a. To 530c.

  That is, the first concave portion 523 that opens to the front surface side and the first molding concave portion 530a that opens to the rear surface side are communicated via the first communication hole 535a, and the first concave portion 523 that opens to the front surface side opens to the rear surface side. The second molding recess 530b communicates with the second communication hole 535b. The first recess 523 that opens on the front surface side and the third molding recess 530c that opens on the rear surface side pass through the third communication hole 535c. (See FIG. 15).

  Further, as shown in FIG. 15, the vertical cross-sectional areas of the first to third communication holes 535a to 535c are the bottom surface 523a (front surface) of the first recess 523 and the bottom surfaces 530t (first to third molding recesses 530a to 530c). Smaller than the rear surface). That is, the first to third molding recesses 530a to 530c are not directly formed in the bottom surface 523a of the first recess 523, but a part of the bottom surface 523a of the first recess 523 and the first to third moldings. A part of the bottom surface 530t of the recesses 530a to 530c is communicated with the first to third communication holes 535a to 535c having a size through which a liquid agent (including washing water and the like) during the plating process can flow. In FIG. 14B, the halftone dot region indicates the region of the first to third communication holes 535a to 535c occupying the bottom surface 530t.

  In this way, a part of the bottom surface 523a of the first recess 523 and a part of the bottom surface 530t of the first to third molding recesses 530a to 530c are communicated via the first to third communication holes 535a to 535c, and the liquid agent is communicated. By being configured with small holes that can be circulated, a decrease in strength can be prevented as compared to the case where the first to third molding recesses 530a to 530c are directly formed through the bottom surface 523a of the first recess 523. .

  In addition, the bottom surface 523a and the bottom surface 530t are formed in a flat shape with each other, and are arranged in parallel with each other, and the portions having the narrowest separation width between the bottom surface 523a and the bottom surface 530t are first to third. Since the lengths of the first to third communication holes 535a to 535c are shortened as much as possible by communicating with the communication holes 535a to 535c, the liquid agent is prevented from staying in the communication holes.

  Further, although the screw hole 530d is formed at a location corresponding to the bottom surface 523a of the first recess 523, as shown in FIG. 14C, the screw hole 530d does not penetrate the front plate portion 520 and has a communication hole or the like. There is no communication through. Accordingly, the diameter of the screw is such that the screw can be screwed (for example, 5 mm or less), and since the liquid agent is difficult to enter due to the cylindrical recess extending in the longitudinal direction, the screw 502a is screwed by the solidified plating layer. It is prevented that the passage portion 521 is broken due to a large resistance force sometimes.

  As shown in FIG. 16, the winning opening member 502 configured as described above includes a single rod-shaped trunk portion 540 a and a plurality of branch portions 540 b branched from the trunk portion 540 a when the winning opening portion member 502 is formed. It is molded together with the runner 540, and is taken out from the molding die in a state where the winning opening member 502 is connected to the tip of the branch portion 540a. In this state, the runner 540 is held by a jig (not shown) and plated, and then the winning hole member 502 is separated at the end of the branch portion 540b, whereby a plurality of winning hole members 502 can be plated simultaneously. It is like that. In this embodiment, the winning opening member 502 is connected to the branch part 540b by the straight part 522, so that it is easy to cut at the time of cutting after the plating process described below.

Here, an example of a rough flow of the plating process will be described. First, the plating process is roughly divided into setup, degreasing, various plating, drying, and inspection, and details are as follows.
1. Setup (material, shape, quantity, required function, current density, jig design)
2. Substrate adjustment, masking (If the surface of the material is not suitable for plating or the surface is rough, adjust the surface)
3. Jig selection, jig attachment (Select and install the jig that suits the product, or place it in the barrel)
4). Pre-degreasing (removing a large amount of oil)
5. Degreasing (removing moderately attached oil)
6). Wash with water (wash away the liquid adhering to the previous process)
7). Pickling (removes rust, scale, smut, etc.)
8). Wash with water (wash away the liquid adhering to the previous process)
9. Finish cleaning (removes very small amounts of oil and smut)
10. Wash with water (wash away the liquid adhering to the previous process)
11. Activation (removes the oxide film generated in the pretreatment process)
12 Wash with water (wash away the liquid adhering to the previous process)
13. Various plating (deposit various metal films on the surface of the material)
14 Collect (collect the plating solution drawn by the product)
15. Wash with water (wash away the liquid adhering to the previous process)
16. Activation (Activate the surface after galvanization)
17. Wash with water (wash away the liquid adhering to the previous process)
18. Various chromate treatments (add chromic oxide compound on galvanized)
19. Wash with water (wash away the liquid adhering to the previous process)
20. Dry (dry the item)
21. Remove jig (Remove from jig, take out from hopper, etc.)

  As described above, since the quality of the plating state may be deteriorated due to the retention of the liquid agent used in the plating process in the plating process, careful attention should be paid to the plating process of a decorative article having a complicated shape. It is necessary to pay and process, but if this has caused a reduction in work efficiency, there is a risk that productivity will be significantly reduced.

  Next, the effect | action in a plating process is demonstrated based on FIG. In FIG. 17, only the distribution state of the plating solution M between the first recess 523 and the third molding recess 530c will be described, and the first recess 523 and the first and second molding recesses 530a and 530b will be described. Since the flow of the liquid agent between the two is the same, the description here will be omitted.

  First, as shown in FIG. 17A, the runner 540 is held by a jig (not shown), and the winning prize opening member 502 is maintained in a predetermined posture. At this time, for example, the first recess 523 is lowered while facing the inclined surface inclined at about 45 degrees with respect to the water surface of the plating solution M. Here, when the first concave portion 523 is immersed in the plating solution M in a posture in which the first concave portion 523 is opened downward, the air in the first concave portion 523 passes through the third communication hole 535c located on the upper side, and the third molding concave portion. Since it is discharged into 530c, it does not stay inside. That is, the third communication hole 535c functions as an air vent hole of the first recess 523. Therefore, since the liquid agent spreads evenly over almost the entire inner surface of each of the first recess 523, the communication hole 535c, and the third molding recess 530c, it is possible to prevent a plating failure from occurring in the next process. Further, since the winning ball guiding groove 525 is opened upward, the liquid agent M spreads evenly over almost the entire inner surface.

  Next, as shown in FIG. 17B, after rotating from the tilted posture to a vertical posture, the entire winning opening member 502 is immersed in the liquid agent, and then raised while returning to the tilted posture again.

  Then, as shown in FIG. 17C, the liquid agent in the first recess 523 flows down at the same time that the liquid agent M is pulled up from the liquid agent M, and the liquid agent in the third molding recess 530c that opens upward is the bottom surface 530t. It flows out through the third communication hole 535c formed in the bottom and flows down from the first recess 523. Further, since the winning ball guiding groove 525 is also opened obliquely downward, the liquid agent almost flows down.

  As described above, the liquid agent in the third molding recess 530c is quickly discharged, so that the liquid agent stays in the third molding recess 530c during the plating process or after the plating process. If it is inside, it cannot be wiped even with water washing before the next process, and due to vibration in the next process, the third molding recess 530c is inadvertently flowed out from the rear end opening, and processing in this next process It is possible to prevent the occurrence of plating defects due to defects.

  In the present embodiment, the first recess 523 is immersed while facing the inclined surface inclined by about 45 degrees with respect to the water surface of the plating solution M, but the posture when immersed in the solution M is arbitrary, For example, the third molding recess 530c may be lowered and immersed in the liquid M in a posture in which the third molding recess 530c is opened downward.

  Further, in this embodiment, the first concave portion 523 and the third molding concave portion 530c (second concave portion) face each other in a posture in which a concave portion having a large opening area or a small depth dimension is inclined with respect to the liquid agent M. By soaking in the state of being made to enter, the air does not easily enter the first recess 523 facing the liquid agent M, and the air that has entered enters the third molding recess 530c (the first side through the communication hole 535c). (2 recesses) can be quickly discharged, so that the liquid M is surely distributed inside both the first recess 523 and the third molding recess 530c, so that plating defects are less likely to occur.

  Then, the winning hole member 502 that has been plated in this way is attached to and integrated with the front surface of the winning hole mounting member 501 with a screw 502a as shown in FIG. In the integrated state, as shown in FIGS. 13B and 13C, a substantially square winning opening that opens upward by the front plate portion 520, the left and right side walls of the passage portion 521, and the mounting plate portion 505. (For example, the start winning port 13a, the winning ports 29a to 29d) are formed, and the front and rear winning ball guiding grooves 525 and 509 are matched via the passage hole 504 to form a winning ball guiding passage extending in the front and rear direction. .

  In addition, a decoration seal 503 having a predetermined decoration on the front surface is attached to the bottom surface 523a of the first recess 523. Accordingly, the plurality of first to third communication holes 535a to 535c formed on the bottom surface 523a are covered from the front side and hidden from the player side so that they cannot be seen from the player side. It is possible to prevent an illegal act from being performed on the game control board 31 provided on the back side of the game board 6 by entering a foreign object such as a wire from the communication holes 535a to 535c.

  As described above, one of the first recess 523 and the first to third molding recesses 530a to 530c, which are the second recesses, is immersed in the plating solution in a posture that opens downward, so that the first to third moldings are used. Even if air is trapped in the recesses 530a to 530c, air can escape from the other first to third molding recesses 530a to 530c via the first to third communication holes 535a to 535c, so that the recesses are uneven. And can be plated. Further, when the winning opening member 502 is pulled up from the liquid agent M, the liquid agent staying in the first to third molding recesses 530a to 530c in the posture of opening upward is passed through the first to third communication holes 535a to 535c. Since it is discharged from the other concave portion, it is possible to prevent a plating failure.

  In particular, since the first recess and the second recess communicate with each other via the communication hole, it is not necessary to provide a communication hole corresponding to each recess, and the opening of the communication hole is formed between the first recess and the second recess. It is formed on the inner surface, and the opening is not exposed to a portion other than the concave portion on the surface of the winning opening member 502.

  In addition, the openings of the first to third communication holes 535a to 535c are not exposed to places other than the first recess 523 and the first to third molding recesses 530a to 530c on the surface of the winning opening member 502, and the first Since the plating treatment area is increased by the liquid M flowing into the three communication holes 535a to 535c, for example, the electricity charged in the game ball won in the winning opening is easily discharged. Furthermore, the plating area is further increased by applying the plating process to the winning opening attaching member 501, and the winning opening attaching member 501 is attached to the board plate 200 larger than the winning opening attaching member 501. As a result, the static elimination effect is enhanced.

  In particular, the first to third molding recesses 530a to 530c as the second recesses are molding recesses formed in the passage portion 521 in which the game ball guiding groove 525 for guiding the game ball is formed. Since the plating treatment area of 521 increases, electricity can be removed while guiding the winning game ball. Further, even if the first to third molding recesses 530a to 530c are formed in the passage portion 521, the passage portion 521 is maintained in a cylindrical shape, so that the strength is not significantly reduced.

  Also, the first to third molding recesses 530a to 530c are formed at positions that open on the opposite side of the first recess 523, and the first to third communication holes 535a to 535c are the first recess 523 and the first to third moldings. The first to third communication holes 535a to 535c are lengthened and the liquid M and air are likely to stay by communicating between the portions having the smallest separation width with the concave portions 530a to 530c, that is, between the bottom surface 523a and the bottom surface 530t. Is prevented.

  In the present embodiment, the first recess is formed on the front surface and the second recess is formed on the back surface on the opposite side so that the first recess and the second recess open in the front-rear direction. On the other hand, the 2nd crevice may be formed in any of a right-and-left side, a plane, and a bottom. Further, as in this embodiment, a plurality of second recesses (first to third molding recesses 530a to 530c) may be formed with respect to the first recess, or a plurality of first recesses and a plurality of first recesses may be formed. The two recesses may be communicated with each other on a one-to-one basis.

  The first to third communication holes 535a to 535c are formed between the shortest distances so as to communicate the bottom surface 523a and the bottom surface 530t. For example, the surfaces other than the bottom surface 523a and the bottom surface 530t are communicated with each other. It may be formed.

  In the present embodiment, the first to third communication holes 535a to 535c are formed along a part of the periphery of the bottom surface 530t of the bottom surface 523a and the bottom surface 530t, so that the first to third communication holes are formed. When a part of the inner peripheral surface of the holes 535a to 535c and a part of the inner peripheral surface of the first to third molding recesses 530a to 530c are flush with each other and no stepped portion is formed, the liquid M is pulled up. In addition, the liquid agent M in the first to third molding recesses 530a to 530c surely flows down without staying in the stepped portion.

  The winning opening member 502 is a winning opening member that constitutes the game balls winning openings 13a, 29a to 29d provided on the gaming board 6 and a game ball guiding path for guiding the game balls that have entered the winning opening. The first to third molding recesses 530a to 530c are molding recesses that are formed to make the passage portion 521 (thickness portion) constituting the game ball guiding path hollow. Even without forming a cutout groove or the like for communicating the recesses 530a to 530c to the outside, it entered the inside through the first to third communication holes 535a to 535c formed in the first to third molding recesses 530a to 530c. Since air or liquid M can be discharged, it is possible to prevent a decrease in strength of the game ball guiding path. Further, since the surface is plated from the surface of the game ball guiding groove 525 formed in the passage portion 521 to the first to third molding recesses 530a to 530c, the plating processing area is expanded. Static electricity from passing game balls can be effectively removed.

  Further, in this embodiment, the winning opening member 502 is molded in a state of being connected to the runner 540, and during the plating process, the runner 540 is held by a jig (not shown) and immersed in the liquid M, as shown in FIG. As described above, a locking portion 552 that is bent laterally at the tip may be formed, and may be held using a jig 550 having a pair of left and right bar members 551 formed to be elastically deformable.

  Specifically, the pair of left and right bar members 551 have a length that can be inserted from the rear end openings of the first and second molding recesses 530a and 530b to the front side through the first and second communication holes 535a and 535b. When the front plate 520 is inserted into the first recess 523 (not shown), the pair of left and right locking portions 552 are elastically locked to the left and right edges of the first and second communication holes 535a and 535b. As a result, deviations are regulated.

  As described above, the jig 550 that holds the winning hole member 502 when performing the plating process is provided, and the winning hole member 502 has one of the first recess 523 and the first and second molding recesses 530a and 530b facing downward. The first and second molding recesses 530a and 530b to which the jig 550 is attached are formed so that the liquid agent M is discharged well.

  FIG. 19 shows a winning opening member 502A as a first modification of the present invention.

  In the winning opening member 502 of the above embodiment, the screw hole 530d is formed at a position corresponding to the bottom surface 523a of the first recess 523, but does not penetrate the front plate 520 and communicates through a communication hole or the like. However, as in the first modification, the first recess 523 and the screw hole 530d may be communicated with each other via the fourth communication hole 535d. By doing so, the diameter is reduced. Air or liquid M entering the long screw hole 530d can be discharged from the fourth communication hole 535d.

  Note that the opening area of the fourth communication hole 535d may be smaller than or equal to the outer diameter of the screw hole 530d, and in the case of being the same, the screw hole 530d is formed through the bottom surface 523a. Will be.

  In this way, the first recess 523 and the screw hole 530d communicate with each other through the fourth communication hole 535d, so that the plating process is also performed in the screw hole 530d. Therefore, since the metal screw 502a is screwed into the screw hole 530d, the static electricity generated in the winning hole member 502 escapes to the screw 502a. Can be released to the winning opening attaching member 501.

  FIG. 20 shows a winning opening member 502B as a second modification of the present invention.

  In the prize port member 502 of the embodiment, each of the first to third molding recesses 530a to 530c was merely communicated with the first recess 523 via the first to third communication holes 535a to 535c. For example, by forming the notch groove 560 extending in the front-rear direction on the bottom wall of the third molding recess 530c, the liquid M that has entered the third molding recess 530c can be more reliably discharged. In this case, the first bottom wall portion 560a directly forming the winning ball guiding groove 525 is not divided by the notch groove, and the second bottom wall portion 560b below the third molding recess portion 530c is sandwiched. Therefore, the strength of the bottom wall portion of the winning ball guiding groove 525 is not significantly reduced.

  Further, in this embodiment, the winning opening member 502 constituting the winning opening of the variable winning ball apparatus has been described as an example of the plating member. However, the first recessed portion that opens toward one side and the second opening that opens toward the other side are described. If it is a member in which the recessed part was formed, it will become the object of the plating member of this invention.

  The second special variable winning ball device 24 shown in FIGS. 21 to 24 is provided on the center frame decoration 11 formed so as to surround the effect display device 9 as shown in FIG. The center frame ornament 11 is formed of a synthetic resin material in an annular shape, and is composed of a plate-like portion 11a arranged along the front surface of the board surface plate 200 at the periphery of an opening (not shown) formed in the board surface plate 200. Various decorative members are applied to the front surface of the plate-like portion 11a.

  The second special variable winning ball apparatus 24 includes a second large winning opening 24c formed in the plate-like portion 11a, and an open position where a game ball can easily win the second large winning opening 24c (see FIG. 28B). Mainly composed of a blade member 600 that is pivotable between a closed position (see FIG. 28A) in which a game ball does not win or is difficult to win, and a drive unit 601 that drives the blade member 600. Has been.

  The second grand prize winning port 24c includes an upper portion of an inclined side surface 610a formed on a triangular prism-shaped block wall 610 protruding from the front surface of the plate-like portion 11a, and a second count switch 24a horizontally disposed below the lower side. This is a vertical winning opening that opens between the left end and the left side. A sensor holding portion 604 having a pair of left and right holding grooves 604a (see FIG. 26A) extending in the front-rear direction is formed in the lower portion of the block wall 610, and a second count switch is provided in the holding groove 604a. The main body 24a can be inserted from the back side.

  As shown in FIG. 22, the main body 24A of the second count switch 24a is made of a flat plate member having a rectangular shape in plan view, and a passage hole 24B (detection opening) through which a game ball can pass is formed so as to penetrate vertically. A game ball that enters (wins) from the second grand prize opening 24c and passes through the passage hole is detected.

  Below the sensor holding portion 604, a guide that constitutes a winning ball guiding passage 605a that guides the game ball guided downward through the passage hole 24B of the second count switch 24a to the back side of the plate-like portion 11a. A collar 605 is formed. As shown in FIG. 26 (a), the guide rod 605 is made of a plate member formed in a U-shape that is substantially upward in the longitudinal section, and extends toward the back side.

  In addition, a protective wall 606 that prevents the game ball from colliding with the blade member 600 is erected on the left side of the blade member 600 on the front surface of the plate-like portion 11a. The detailed structure of the protective wall 606 will be described later.

  The blade member 600 and the drive unit 601 that drives the blade member 600 will be described. As shown in FIG. 22, the drive unit 601 is a solenoid 22 as a drive source fixedly provided at a predetermined position on the upper back of the plate-like portion 11a. And a connecting member 620 provided at the tip of the plunger 22a of the solenoid 22 and an eccentric shaft member 621 connected to the connecting member 620, and facing a direction (front-rear direction) substantially orthogonal to the front surface of the panel board 200. The rotary shaft 622 is mainly configured.

  The rotating shaft 622 is inserted into a bearing hole 607 formed in the plate-like portion 11a facing in the front-rear direction so as to be rotatable around the axis, and the blade member 600 is fixed to the front end and the eccentric shaft member is fixed to the rear end. 621 is fixed. An eccentric shaft 621 a that is in an eccentric position with respect to the axis of the rotation shaft 622 is provided on the eccentric shaft member 621 so as to protrude rearward.

  As shown in FIGS. 22, 24 (b), 26 (b), and 27, the connecting member 620 includes a mounting plate 620a that is mounted perpendicular to the tip of the plunger 22a, and a rear edge of the mounting plate 620a. The connecting plate 620b is provided continuously from the top and faces the plate-like portion 11a, and the guide plate 620c is provided continuously from the bottom of the mounting plate 620a and extends in the horizontal direction. A connecting hole 623 extending in the vertical direction is formed in the connecting plate 620b, and an eccentric shaft 621a is slidably inserted into the connecting hole 623 in the longitudinal direction so that the plunger 22a, the rotating shaft 622, Are connected via a connecting member 620. The guide plate 620c is slidably inserted in the left-right direction into a guide groove 608 (see FIGS. 22 (b) and 26 (b)) whose front end is formed on the back surface of the plate-like portion 11a and faces in the left-right direction. Thus, the connecting member 620 is slidably guided in the left-right direction.

  In the drive unit 601 configured as described above, as shown in FIG. 27B, in the state where the solenoid 22 is not excited (solenoid 22; off), the plunger 22a is moved to the protruding position by the urging force of the coil spring 22b. To position. In this state, the connecting hole 623 and the eccentric shaft 621a are maintained at a position eccentric to the right side when viewed from the front with respect to the axis of the rotation shaft 622, and the blade member 600 is stopped at the closed position.

  As shown in FIG. 27C, when the solenoid 22 is excited (solenoid 22; on), the plunger 22a moves to the retracted position on the main body side against the biasing force of the coil spring 22b. When the connecting member 620 moves to the main body side of the solenoid 22 together with the plunger 22a, the eccentric shaft 621a fitted in the connecting hole 623 is rotated around the axis of the rotating shaft 622. As a result, the rotation shaft 622 rotates counterclockwise as viewed from the front, and the blade member 600 rotates around the rotation shaft 622 from the closed position to the open position.

  As shown in FIG. 25, the blade member 600 protrudes from the plate-like portion 11a, that is, the front plate portion 630 provided substantially in parallel to the front surface of the board plate 200, and a predetermined position on the back surface of the front plate portion 630. A cylindrical bearing portion 631 having a fitting hole 631a into which the front end of the rotating shaft 622 is fitted so as not to be relatively rotatable, and a stopper projecting at a position near the bearing portion 631 on the back surface of the front plate portion 630. The piece 632, the inner wall portion 633 standing from the edge of the back surface of the front plate portion 630 on the side of the second big prize opening 24 c toward the board plate 200, and the second big prize opening 24 c on the back surface of the front plate portion 630. An outer wall 634 that is erected from the edge opposite to the board surface plate 200, and an inner wall 633 and an outer wall 634 that are erected from the upper rear edge of the front plate 630 toward the board plate 200. Connecting the upper side wall And 35, are constructed from.

  As shown in FIG. 26 (a), the tip of the stopper piece 632 is fitted into a rotation restricting groove 609 formed in a concentric arc shape above the bearing hole 607 in the plate-like portion 11a, and is in the closed position. Is located at the right end of the rotation restricting groove 609 and is located at the left end of the turn restricting groove 609 in the open position, and is brought into contact with the left end or the right end of the turn restricting groove 609 so that the rotation is about 90%. Regulated within a range of degrees.

  As shown in FIG. 25, the front plate portion 630 is a long plate extending in one direction, and a bearing portion 631 is formed at a position slightly shifted to one end side from the central position in the longitudinal direction. . That is, the blade member 600 is extended from the bearing portion 631 in one direction orthogonal to the axis of the rotation shaft 622 and from the bearing portion 631 to the opposite side to the one direction. Base portion 600b.

  In the ball receiving portion 600a, a thickness dimension L20 in a direction (front-rear direction) orthogonal to the front surface (game board surface) of the board face plate 200 substantially corresponds to the diameter dimension P of the game ball (L20≈P, see FIG. 29), and the blade This is a part that restricts the entry of the game ball into the second big prize opening 24c when the member 600 is in the closed position. Moreover, the thickness dimension L21 of the base part 600b is narrower than the ball receiving part 600a (L20> L21).

  In the present embodiment, the thickness dimension L20 of the ball receiving portion 600a is a dimension substantially corresponding to the diameter dimension P of the game ball, but the dimension substantially corresponding to the diameter dimension P of the game ball is, for example, It is preferably within the range of about half the diameter P of the game ball to about twice the diameter P. When the diameter P of the game ball is 11 mm, it is within the range of 5.5 mm to 22 mm. If it is.

  That is, the outer wall portion 634 extends from the rear upper end of the front plate portion 630 to a position slightly below the side of the bearing portion 631 along the outer side. In other words, the ball receiving portion 600a and the base portion 600b extend along a part of the outer side, but the notch 636 is formed in the lower half of the bearing portion 631 from a slightly upper position to the lower end. Thus, the first outer side surface 634a from the upper end to the notch 636 and the notch are substantially extended only from the upper end of the back surface of the front plate 630 to the side of the bearing 631 and slightly above the outer side. 636 and a second outer side surface 634b arranged in parallel with each other. Further, the notch 636 is formed to be slightly larger than the protective wall 606 at a location corresponding to the protective wall 606, and interferes with the protective wall 606 when the blade member 600 is positioned at the closed position or rotated. It is formed so as not to.

  The inner wall portion 633 extends from the rear upper end of the front plate portion 630 to the side position of the bearing portion 631 along the inner side. That is, it extends along the inner side of the ball receiving portion 600a and is not formed on the inner side of the base portion 600b. And the inner side surface 633a of this inner side wall part 633 comprises the inner side surface 633a which receives a game ball.

  As shown in FIG. 28A, the protective wall 606 is disposed at a position corresponding to the notch 636 of the blade member 600 in the closed position. Specifically, the upper inclined wall 606a that extends along the outer side of the blade member 600 and inclines outward (left side) downward at the closed position and the lower inclined wall 606a are continuously provided from the lower end. The lower inclined wall 606b inclined inward (right side) downward is formed into a substantially “<” shape.

  Further, as shown in FIG. 29, the protruding length dimension of the protective wall 606, that is, the length dimension L22 from the front surface to the tip of the plate-like portion 11a is formed longer than the diameter P of the game ball (P <L22) The thickness dimension L22 in the direction orthogonal to the front surface of the board plate 200 is formed wider than the thickness dimension L21 of the base portion 600b (L22> L21).

  On the other hand, the game area 7 is formed between the front surface (game board surface) of the board surface plate 200 and the glass plate 102a of the glass door frame 102 disposed on the front surface side of the board surface plate 200. Since the dimension L23 is larger than the diameter P of the game balls and is shorter than the total width of the diameters of the two game balls (P <L23 <2P), the two game balls are placed on the game board surface. It does not flow down in a state of being arranged side by side along. Then, the thickness width dimension L20 of the ball receiving portion 600a and the thickness width dimension L22 of the protective wall 606 each have a width dimension that is more than half of the separation width dimension L23, and thus move along the front surface of the panel board 200. Abuts securely on the game ball.

  Further, since the total dimension of the thickness width dimension L22 of the protective wall 606 and the thickness dimension L21 of the base portion 600b is wider than the diameter dimension P of the game ball (L21 + L22> P), the base portion 600b with respect to the protective wall 606. By attaching the blade member 600 so as to overlap in the front-rear direction, in the closed position, the outer surface 606c of the protective wall 606 and the second outer surface 634b of the base portion 600b are moved in the front-rear direction so as to block the flow of the game ball Side by side.

  In other words, at least in the closed position, a part of the outer wall portion 634 of the blade member 600 that prevents the game ball from entering the second big prize opening 24c is a plate-like portion that is a fixing member to which the blade member 600 is attached. It is comprised by the protective wall 606 protrudingly provided by the front surface of 11a.

  When the blade member 600 is in the closed position, the base portion 600b is placed on the protective wall 606 such that the outer side surface 606c (outer wall portion) of the protective wall 606 protrudes outward from the second outer side surface 634b of the base portion 600b. Since they are attached so as to overlap in the front-rear direction (see FIGS. 28 and 29), contact with the base portion 600b is prevented.

  In the present embodiment, the outer surface 606c (outer wall portion) of the protective wall 606 is arranged so as to protrude outward from the second outer surface 634b of the base portion 600b when in the closed position. The side surface 634b and the outer surface 606c may be disposed so as to be substantially flush with each other.

  Further, the upper inclined wall 606a is obliquely extended from the upper left position to the lower left position of the rotation shaft 622 so that the game ball moving from the upper left side can be rotated by the rotation shaft in the front plate portion 630. Since it is prevented from colliding with the base portion 600b below 622, the ball receiving portion 600a is prevented from forcibly rotating in the opening direction when the game ball collides with the base portion 600b at the closed position. it can.

  Next, the operation of the second special variable winning ball apparatus 24 configured as described above will be described with reference to FIGS.

  As shown in FIG. 28 (a), the blade member 600 is maintained in a standing posture in which the blade member 600 stands up in the closed position. At this time, the ball receiving portion 600a is disposed above the rotation shaft 622, and the base portion 600b is disposed below the rotation shaft 622 by closing the second big prize opening 24c with the inner side surface 633a. Therefore, when the game ball collides with the second outer side surface 634b of the base portion 600b, when the impact is larger than the urging force of the coil spring 22b, the blade member 600 is counteracted when viewed from the front with the rotation shaft 622 as the center. Since the ball receiving portion 600a rotates in the opening direction by rotating clockwise, the blade member 600 is slightly opened each time the game ball collides with the base portion 600b.

  However, in this embodiment, when the blade member 600 is in the closed position, the outside of the base portion 600b (the game area 7 side) is covered with the protective wall 606, so that the game ball directly collides with the base portion 600b. Is prevented. That is, as shown in FIG. 29, in the game area 7 formed between the front surface of the board surface plate 200 and the back surface of the glass plate 102a, the movable blade member 600 is located below the blade member 600 in the closed position. The second outer side surface 634b formed on the front side of the plate-like portion 11a and the outer side surface 606c of the protective wall 606 standing on the front surface of the plate-like portion 11a are juxtaposed in the front-rear width direction so as to prevent the game ball from flowing down, The outer surface 606c has a larger dimension in the thickness width direction than the second outer surface 634b (L22> L21), so that the occupied area with respect to the separation width dimension L23 is fixed more than the movable second outer surface 634b. Since the side surface 606c is larger, the outer surface 606c is easier to hit the game ball than the second outer surface 634b. Therefore, the blade member 600 is slightly opened due to the collision with the game ball, and the game ball is prevented from entering the second big prize opening 24c by mistake.

  In particular, in the present embodiment, the second special variable winning ball device 24 is guided to the upper left side of the center frame decoration 11, that is, the upper left side of the game area 7 after being guided from the hitting ball launcher 65 to the upper left side of the game area 7. The outer surface 606c of the protective wall 606 and the outer wall portion 634 of the blade member 600 are connected to the inflow portion 7a at a so-called “bulging” position where the projecting ball entering the inside directly from the inflow portion 7a (see FIG. 1) reaches. Since it is provided toward the side, the wing member 600 is damaged by the game ball colliding from the direction substantially orthogonal to the outer wall 634 and the protective wall 606, or the second grand prize winning opening 24c is inadvertently opened. Is prevented.

  Here, when the solenoid 22 is excited and the blade member 600 rotates counterclockwise toward the open position, the protection wall 606 does not interfere with rotation. That is, the notch 636 is formed and the inside is hollow so that the protective wall 606 enters the back side of the front plate 630 according to the rotation.

  Then, as shown in FIG. 28 (b), in the open position, the upper end is rotated about 90 degrees outward (left side) and maintained in a tilted posture tilted obliquely. At this time, the ball receiving portion 600a is disposed above the rotation shaft 622, and the inner side surface 633a assumes an upward tilting posture that gently tilts downward from the upper end to the lower end. A ball receiving surface that guides to the special winning opening 24c is formed.

  In this state, the upper end of the protective wall 606 and the inner surface of the inner wall portion 633 are close to each other, but the rotation range is regulated by the stopper piece 632 coming into contact with the left end of the rotation regulating groove 609. All impacts of the ball receiver are distributed to the plate-like portion 11a.

  Further, in the plate-like portion 11a, a predetermined effect member 640 (a star-shaped decorative member in the present embodiment) is visually recognized from the player side on the lower back side of the front plate portion 630 in the blade member 600 located at the closed position. It is impossible. Therefore, when moving to the open position, the lower portion of the front plate portion 630 located in front of the effect member 640 is moved to the side, thereby exposing the effect member 640 and being visible from the player side. Thus, the decoration aspect of the effect member 640 can be changed using the rotation operation of the blade member 600.

  As described above, the second special variable winning ball apparatus 24 according to the embodiment of the present invention is mounted so that the blade member 600 is attached to the plate-like portion 11a which is a fixed member when the blade member 600 is in the closed position. The protective wall 606 formed in the portion is arranged such that the outer side surface 606c protrudes outward with respect to the second outer side surface 634b of the base portion 600b, and has a thickness dimension wider than that of the base portion 600b. When the game ball moves toward the base portion of the blade member 600, the protective wall 606, which is a fixed portion protruding from the plate-like portion 11a that is a fixed member, rather than the base portion 600b of the movable blade member 600. The probability of colliding with is higher. The outer side with respect to the second outer side surface 634b is the front side or the upstream side in the flow-down direction of the game ball.

  Therefore, it is possible to prevent the game ball from colliding with the base portion 600b extending below the rotation shaft 622 and rotating the ball receiving portion 600a on the opposite side across the rotation shaft 622 as much as possible. In addition, the game ball does not collide with the rotation shaft 622 so that the blade member 600 cannot be rotated.

  Further, the protective wall 606 forms a part of the outer wall portion 634 (outer surface) of the blade member 600 that prevents the game ball from entering the second big prize opening 24c at least in the closed position. Since it is provided in a standing posture intersecting with the front surface of 200, it can be widely provided from the front surface of the board surface plate 200 toward the glass plate 102a, so that the entry of the game ball can be surely prevented.

  Further, in this embodiment, the base portion 600b is disposed on the glass plate 102a side, the protective wall 606 is disposed on the back side thereof, and the front plate portion 630 constituting the base portion 600b is substantially the same as the board surface plate 200. By being constituted by plate members arranged in parallel, the protective wall 606 is hidden behind the front plate portion 630 and is not conspicuous when viewed from the front, which can give the player a sense of incongruity. Absent. Further, even when rotating to the open position, since it enters the back side of the front plate 630, it does not hinder the rotation.

  Further, the blade member 600 includes a front plate part 630 provided substantially parallel to the front surface of the board plate 200, an inner wall part 633 standing from the edge on the back surface of the front plate part 630 toward the board plate 200, By being formed in a hollow shape from the outer side wall portion 634 and the side wall portion consisting of the upper side wall portion 635, the protective wall 606 and the front plate portion 630 can be overlapped in the front-rear direction so as not to interfere during rotation. As a result, the rotation range is hardly restricted by the protective wall 606, so that the range in which the game ball is prevented from colliding with the protective wall 606 is expanded (for example, lower than the rotation shaft 622 as in this embodiment). Not only the base 600b but also a part of the ball receiving portion 600a above the rotation shaft 622 can be prevented from colliding with the game ball.

  Further, in the present embodiment, even when the second special variable winning ball device 24 is provided in a place where the game ball flowing into the game area 7 is easy to hit directly, the protective wall 606 prevents the game ball from directly hitting the base portion 600b. Since it can be avoided as much as possible, the blade member 600a is prevented from being damaged or greatly opened due to the collision with the game ball. Even when the second special variable winning ball device 24 provided at the second big winning opening 24c provided at the position where the game ball easily collides is provided, the blade member 600 is released by the collision with the game ball. Can be prevented.

  Further, in the open position, the effect member 640 of the plate-like portion 11a provided on the game board 6 is concealed by the front plate portion 630, so that the aspect of the effect member 640 is changed by the opening / closing operation of the blade member 600. be able to. It may be concealed at the closed position.

  In this embodiment, the rotation range of the blade member 600 is regulated by the stopper pieces 632 coming into contact with the left and right ends of the rotation regulating groove 609. For example, although not specifically illustrated, when the blade member 600 is located at the open position, the inner surface of the inner wall portion 633 comes into contact with the upper end of the protective wall 606 (see FIG. 28B). ), The rotation range may be restricted.

  In this way, since the rotation range can be regulated using the protective wall 606 in the open position, the protective wall 606 can be effectively used in both the closed position and the open position, and the ball receiving surface can be used. Since the inner wall portion 633 having the inner side surface 633a can be directly supported from below, the inner wall 633 is hardly damaged or damaged by the impact of the game ball falling on the inner side surface 633a.

  Although not shown in detail, the second outer side surface 634b of the base portion 600b is arranged within the radius (P / 2) width of the game ball from the back surface of the glass plate 102a, so that the game ball is placed on the glass plate 102a. Since it does not collide with the game ball even if it touches, it becomes possible to reliably avoid the collision with the game ball.

  In the present embodiment, the second special variable winning ball apparatus 24 is provided on the center frame decoration 11 assembled to the board surface plate 200, but may be directly attached to the board surface board 200. That is, the fixing member may be the board surface plate 200, and the protective wall 606 may protrude directly from the board surface plate 200.

  In the present embodiment, the second special variable winning ball device 24 is applied as an example of the variable winning device of the present invention. However, the present invention is applied to, for example, the variable winning ball device 15 and the first special variable winning ball device 23. May be.

  Next, a second special variable winning ball device 24 'as a modification of the present invention will be described with reference to FIG. 30A is a left side view showing a second special variable winning ball apparatus as a modified example, and FIG. 30B is a cross-sectional view taken along line HH of FIG.

  The blade member 600 of the above embodiment is composed of the front plate portion 630 and the inner wall portion 633 and the outer wall portion 634 that are erected from the edge of the front plate portion 630 toward the board surface plate 200. A blade member 650 made of a flat plate member may be used as in the modification. The upper half portion of the blade member 650 is a ball receiving portion 651 having a wide front-rear width dimension, and the lower half portion is a base portion 652 having a front-rear width dimension narrower than the ball receiving portion 651 and the protective wall 660. A rotating shaft 622 is fixed to the. That is, the base portion 652 is configured by forming the notches 653a and 653b on the front and rear sides of the lower half. In addition, the inner side surface 654 which stands up with respect to the board surface plate 200 in the ball receiving portion 651 is a ball receiving surface, and the opposite side is an outer side surface 655.

  Further, the thickness dimension L20 of the ball receiving portion 651 substantially corresponds to the diameter dimension P of the game ball (L20≈P), and the thickness dimension L21 of the base portion 652 is narrower than the ball receiving portion 650 (L20> L21). On the other hand, the projecting length dimension of the protective wall 660, that is, the width dimension L22a + L22b obtained by subtracting the width dimension of a notch groove 661 described later from the length dimension L22 from the front surface to the tip of the plate-like portion 11a is larger than the diameter P of the game ball. In addition to being long (P <L22a + L22b), the thickness dimension L22a + L22b in the direction orthogonal to the front surface of the board plate 200 is formed wider than the thickness dimension L21 of the base portion (L22a + L22b> L21).

  The protective wall 660 is disposed along the blade member 650 at the closed position, and a notch groove 661 is formed in a vertical direction at a position corresponding to the base portion 652, whereby the blade member 650 is closed. Contact between the base portion 652 and the protective wall 660 during the position or rotation is avoided.

  Further, in the closed position, the outer surface 660a of the protective wall 660 is disposed so as to be shifted outward from the outer surface 655 of the base portion 652, so that the game ball contacts the base portion 652 and the ball receiving portion 651 is opened. It does not rotate towards the position.

  Thus, not only the notches 653a and 653b for avoiding the contact with the protection wall 660 on the blade member 650 side, but also the notches for avoiding the contact with the blade member 650 on the protection wall 660 side. A groove 661 may be formed.

  Although not shown in detail, the base portion 652 is arranged within the radius (P / 2) width of the game ball from the front surface of the board surface plate 200, so that the game ball contacts the front surface of the board surface plate 200. Can avoid hitting the game ball.

  Next, the structure of a magnetic sensor mounting portion for mounting a magnetic sensor for preventing an illegal act with respect to a proximity switch provided at each winning opening will be described with reference to FIG. 31A is a perspective view showing a mounting portion of a magnetic sensor, FIG. 31B is a plan view of FIG. 31A, and FIG. 31C is a cross-sectional view taken along the line II of FIG.

  A magnetic sensor mounting portion 680 shown in FIG. 31 is formed at a predetermined position of the center frame decoration 11, for example, and the magnetic sensor G having a rectangular parallelepiped shape can be attached and detached by an elastic locking portion. Specifically, the magnetic sensor mounting portion 680 is erected on the mounting base 681, and is formed at the tip of a pair of upper and lower ribs 682a and 682b extending in the left-right direction so as to be parallel to each other. , 683b and an L-shaped holding wall 684 that holds the corners of the magnetic sensor G held between the upper and lower elastic locking portions 683a, 683b.

  The elastic locking portion 683a is formed at the left end portion of the rib 682a, and the elastic locking portion 683b is formed at the right end portion of the rib 682b and is disposed so as to face each other. Forming openings 685 for molding the elastic locking portions 683a and 683b are formed immediately below the elastic locking portions 683a and 683b in the mounting base 681, whereby the elastic locking portions 683a and 683b are attached. By being separated from the upper surface of the base 681, the elastic locking portions 683a and 683b formed at the tips of the ribs 682a and 682b can be elastically deformed in the horizontal direction as shown in FIG. .

  The elastic locking portions 683a and 683b include an elastic piece 686a disposed above the molding opening 685, a vertical piece 686b bent upward from the tip of the elastic piece 686a, and an inner side of the upper end of the vertical piece 686b. And a locking claw 686c that is provided to protrude.

  As shown in FIGS. 31 (a) and 31 (b), the elastic locking portions 683a and 683b are arranged such that the pair of upper and lower locking claws 686c face each other at substantially the same position in the left-right direction. In the state where the two corners on the diagonal line of the magnetic sensor G are held by the holding wall 684 and the mounting position is determined, the holding wall 684 is locked at the substantially central position of the long side portion on the upper surface of the magnetic sensor G. ing.

  Here, when the magnetic sensor G is attached to the attachment portion 680, the two corners on the diagonal line of the magnetic sensor G are aligned with the left and right holding walls 684 at the upper position of the attachment base 681 as shown in FIG. It will be lowered in the state that has been.

  As shown in FIG. 31 (c), the upper surface of the locking claw 686c is a tapered surface inclined inwardly downward, and the tapered surfaces of the pair of upper and lower locking claws 686c are inverted "C" shapes. By simply disposing the magnetic sensor G from the upper side along the tapered surface, the upper and lower elastic locking portions 683a and 683b are elastically deformed in the horizontal direction and opened outward. When the magnetic sensor G is placed on the mounting portion 680, the locking claw 686c is positioned on the upper surface of the magnetic sensor G, so that it is locked by the elastic restoring force and magnetically by the upper and lower elastic pieces 686a. Since the upper and lower side surfaces of the sensor G are held, the movement in the horizontal direction and the upward deviation are restricted, and the sensor G is attached to the attachment portion 680.

  In this way, the locking claw 686c for locking upward deviation is not provided at the upper end of the elastic piece extending in the vertical direction, but is formed on the elastic piece 686a extending in the horizontal direction, so By sandwiching with the elastic pieces 686a, the movement in the horizontal direction can be restricted in the left-right width direction, so that the stability at the time of attachment is improved.

  In addition, when the height of the object to be locked (magnetic sensor G) is short and the vertical piece 686b is short and cannot be elastically deformed sufficiently, the mounting surface of the mounting base 681 is removed. Rather than when the short vertical piece 686b is erected, it can be sufficiently elastically deformed along the mounting surface of the mounting base 681. Therefore, the vertical width dimension of the vertical piece 686b can be shortened, so that not only the board surface plate 200 or the like which is difficult to be formed with a synthetic resin material can easily provide an elastic locking portion. , Engagement / disengagement operation becomes easy.

  As shown in FIGS. 32 to 33, the first special variable winning ball apparatus 23 includes a first large winning unit 700 formed in a box shape and a decorative panel 701 for decorating the periphery of the first large winning opening 23c ( 1). On the front surface of the first grand prize winning unit 700, a horizontally-long rectangular first major prize winning opening 23c having an opening larger than the second grand prize winning opening 24c is formed, and a decorative panel 701 is formed on the decorative panel 701. It is attached so that the first big prize opening 23c faces the opening 701a for the big prize opening. Further, side walls 701b project from the left and right sides of the special prize opening 701a in the decorative panel 701.

  The first grand prize unit 700 has a base body 702 formed in a box shape whose upper surface is opened by a translucent synthetic resin material, and a size capable of opening and closing the opening of the base body 702. And a base cover 703 formed in a box shape whose lower surface is opened by a synthetic resin material having a hollow shape, and a hollow box body is formed by assembling both. An opening / closing mechanism 705 for driving a grand prize opening door 704 capable of opening and closing the first grand prize opening 23c is provided inside the first grand prize winning unit 700, and the first grand prize winning unit 23c enters from the first grand prize winning port 23c. A winning ball guiding path 706 for guiding the winning ball is formed.

  The winning ball guiding path 706 is extended on the base body 702 from the right side to the left side of the horizontally long first big winning port 23c formed on the front surface thereof along the first big winning port 23c. . A concave groove 725 (see FIG. 35) in which the first count switch 23a is installed is formed on the left side of the winning ball guiding path 706, and a discharge path 707 is disposed rearward on the left side, that is, on the downstream side. A discharge port 707b is formed at the rear end. A discharge rod 708 is suspended downward from the discharge port 707b, and a fourth winning confirmation switch 23b is disposed in the middle thereof.

  In this way, the winning ball that has entered the first grand prize winning port 23 c flows down the winning ball guiding path 706, the first count switch 23 a, and the discharge path 707, and then goes out of the first grand prize winning unit 700 from the discharge port 707 b. After being discharged, the discharge rod 708 flows down. The detailed arrangement structure of the first count switch 23a in the winning ball guiding path 706 will be described later.

  On the back side of the winning ball guiding path 706, a plurality of large winning opening LEDs 710a for illuminating the first large winning opening 23c from the back side are arranged in a plurality of (three in the present embodiment) side by side horizontally. A substrate 710 is disposed along the guide path. Irradiation light from the special prize opening LED 710a is emitted to the front side through a light-transmitting passage side wall 711 (see FIG. 32B) formed on the back surface of the base cover 701. The mouth 23c is illuminated from the back side.

  As described above, the inside of the first big prize opening 23c can be illuminated from the back side by the big prize opening LED 710a as an illumination device, and the first count switch 23a is placed on one side of the big prize opening LED 710a. Since it is installed in a direction substantially orthogonal to the winning opening LED 710a, that is, in the front-rear direction substantially parallel to the light emitting direction, there is no obstacle to illumination by the large winning opening LED 710a.

  In this embodiment, the special prize opening LED 710a is arranged so as to illuminate the first special prize opening 23c from the back side. However, as shown by a two-dot chain line in FIG. The portion that constitutes the bottom surface 706a is formed of a translucent member, and the LED substrate 710A in which the big prize opening LED 710a ′ is disposed below the guidance bottom surface 706a is directed toward the guidance bottom surface 706a. It may be provided so that it can be emitted.

  In this case, the first count switch 23a is erected in the direction intersecting the guide bottom surface 706a and provided at the downstream end of the guide bottom surface 706a, so that the guide bottom surface 706a Since the light from the lower side is not blocked, the inside of the first big prize opening 23c can be effectively illuminated.

  As shown in FIGS. 34 to 37, the opening / closing mechanism 705 is attached to the tip of the plunger 21a of the solenoid 21 and the solenoid 21 that drives the prize winning door 704, the solenoid winning door 704, and moves forward and backward. It is mainly composed of a member 720, and a connecting member 721 that connects the moving member 720 and the special prize opening door 704. The solenoid 21 is provided at a position corresponding to the right side portion of the big prize opening door 704 while the plunger 21a can move in the front-rear direction.

  The moving member 720 includes a mounting plate 720a attached perpendicular to the tip of the plunger 21a, and a moving plate 720b provided continuously from the upper left edge of the mounting plate 720a and facing in the front-rear direction. A connecting hole 722 extending in the vertical direction is formed in the moving plate 720b.

  The connecting member 721 has a connecting plate 721 a that stands up in the front-rear direction, and a rotating shaft that protrudes from the left and right side surfaces of the connecting plate 721 a and that is supported by a bearing portion 723 provided on the base body 702 and that faces in the left-right direction. 721b, projecting at a position above the rotation shaft 721b on the left side surface of the connection plate 721a, projecting to a connection pin 721c inserted into the connection hole 722, and projecting to a front position of the rotation shaft 721b on the left side surface of the connection plate 721a. It is comprised from the stopper pin 721d provided and the engagement piece 721e formed in the front part of the connection board 721a.

  The grand prize winning door 704 is provided on the base body 702 so as to project from a horizontally long plate-like plate member 704a formed substantially in the same shape as the first big prize winning opening 23c, and at the lower part of the left and right side end faces of the plate member 704a. A rotating shaft 704b facing in the left-right direction received and supported by the bearing portion 724, a contact piece 704c protruding rearward from the right side of the back surface of the plate member 704a and capable of contacting the stopper pin 721d from above; An engaging pin 704d that protrudes from the right side surface of the contact piece 704c and can be engaged with the engaging piece 721e from below is formed.

  As shown in FIG. 37 (a), the opening / closing mechanism 705 configured as described above has the plunger 21a in the protruding position by the biasing force of the coil spring 21b when the solenoid 21 is not excited (solenoid 21; off). To position. In this state, the connection hole 722 and the connection pin 721c are positioned on the front side with respect to the axis of the rotation shaft 721b, so that the engagement piece 721e at the front end tilts downward and pushes down the engagement pin 704d. While the plate member 704a is in the standing posture, the contact piece 704c contacts the stopper pin 721d from above and further rotation is restricted, so that the plate member 704a is maintained in the closed position.

  That is, the plate member 704a provided so as to be rotatable about the rotation shaft 704b is urged to rotate counterclockwise in FIG. 37 by the engagement pin 704d being pressed downward by the engagement piece 721e. However, since the contact piece 704c comes into contact with the stopper pin 721d and the rotation in the counterclockwise direction is restricted, the clockwise and counterclockwise rotation is restricted, so that the upper portion of the plate member 704a It is difficult to release even if it is pulled to the near side or pushed to the back side.

  As shown in FIG. 37B, when the solenoid 21 is excited (solenoid 21; on), the plunger 21a moves (retreats) to the retracted position on the main body side against the biasing force of the coil spring 21b. When the moving member 720 moves to the main body side of the solenoid 21 together with the plunger 21a, the connecting pin 721c fitted in the connecting hole 722 is rotated around the axis of the rotating shaft 721b. As a result, the connecting member 721 rotates counterclockwise in FIG. 37 about the rotation shaft 721b, whereby the engagement piece 721e at the front end rises and the bias of the engagement pin 704d is released, and the stopper The pin 721d rises to push up the contact piece 704c. Accordingly, the plate member 704a is rotated clockwise in FIG. 37 about the rotation shaft 704b, and is maintained in the open position tilted forward.

  That is, when the solenoid 21 is excited and moves to the open position, the plate member 704a is tilted by its own weight as the engagement piece 721e at the front end rises and the bias of the engagement pin 704d is released. In addition to rotating to the open position, the contact piece 704c is forcibly pushed up by the rising of the stopper pin 721d, so that the speed at the start of the opening operation is higher than when the plate member 704a is rotated by its own weight and opened. Since the speed is increased, it is difficult to cause a deviation between the excitation timing of the solenoid 21 and the opening operation start timing, and although not shown in detail, the contact piece 704c is slightly pushed up by the rise of the stopper pin 721d. Since the plate member 704a is rotated and released by its own weight when the engagement pin 704d is separated from the stopper pin 721d, for example, Even when a game ball to the front side of the plate member 704a at work start is passing, it never will be sandwiched between the glass plates 102a game balls.

  As described above, the plate member 704a provided so as to be rotatable around the rotation shaft 704b is rotated in the counterclockwise direction in FIG. 37 when the engagement pin 704d is pressed downward by the engagement piece 721e. Although biased, the contact piece 704c comes into contact with the stopper pin 721d and the rotation in the counterclockwise direction is restricted, whereby the clockwise and counterclockwise rotations are restricted. Therefore, even if the upper part of the plate member 704a is pulled to the near side, the engagement pin 704d is pressed by the engagement piece 721e, so that it is difficult to be released, and even if the upper part of the plate member 704a is pushed inward, the stopper pin Since the contact piece 704c is regulated by 721d, it is difficult to open to the back side.

  Next, the details of the winning ball guiding path 706 and the discharging path 707 and the first count switch 23a installed in the concave groove 725 formed between the winning ball guiding path 706 and the discharging path 707 will be described. A description will be given with reference to FIGS.

  As shown in FIG. 38, the winning ball guiding path 706 extending along the first major winning opening 23c is formed in an inclined surface shape that gradually inclines downward toward the left side in FIG. 38, that is, toward the discharge path 707. , It has a guide bottom surface 706a that allows the game ball to flow down by rolling. A concave groove 725 is formed in the downstream end portion of the guide bottom surface 706a in the front-rear direction, that is, in a direction crossing the winning ball guide path 706, and further on the downstream side of the concave groove 725, the discharge path 707 is formed. Is extended backwards.

  The discharge passage 707 is formed in an inclined surface shape that gradually inclines downward toward the rear, and has a flow-down bottom surface 707a that allows the game ball to flow down by rolling. Further, the upstream end portion of the flowing bottom surface 707a is provided at a position lower than the downstream end edge portion 706b of the guiding bottom surface 706a, and a discharge port 707b is formed at the downstream end portion of the flowing bottom surface 707a. Has been.

  In this embodiment, the discharge path 707 extends rearward. However, for example, a discharge port 707b may be formed directly on the downstream side of the concave groove 725, and the configuration of the discharge path is variously changed. Is possible.

  On the other hand, as shown in FIG. 39 (a), the first count switch 23a includes a main body 23A made of an elongated flat plate member and a game ball passage hole 23B formed on one end side of the main body 23A. It is a proximity switch and can detect a game ball that has passed through the passage hole 23B. The passage hole 23B is formed in a substantially circular shape, and the diameter L1 is slightly larger than the diameter P (about 11 mm) of the game ball (L1> P).

  As shown in FIG. 33, the first count switch 23 a configured as described above is disposed so that the main body 23 </ b> A crosses the downstream end of the winning ball guiding path 706. Specifically, as shown in FIG. 39B, the first count switch 23a has a perpendicular line X perpendicular to the center of the opening (detection opening) of the passage hole 23B and substantially parallel to the guide bottom surface 706a. It arrange | positions so that it may arrange | position at the approximate center position of the width direction of the guidance bottom face 706a. That is, it arrange | positions with the standing posture made to stand in the direction which cross | intersects with respect to the guidance bottom face 706a.

  Further, in the installed state, a part of the lower long side portion of the main body 23A is loosely fitted in a concave groove 725 formed between the downstream end portion of the guide bottom surface 706a and the flow bottom surface 707a. At the same time, a part of the upper long side portion of the main body 23 </ b> A is held in the standing posture by being fitted into a groove 726 formed in the lower surface of the base cover 703.

  The bottom surface 725a of the concave groove 725 tilts slightly downward toward the downstream side with respect to the guide bottom surface 706a, and the width dimension L11 of the game ball in the flow-down direction is slightly longer than the plate thickness width dimension L3 of the main body 23A. It is formed in the size (L11> L3). Therefore, a predetermined gap L12 smaller than the diameter P of the game ball is provided between the downstream edge 706b of the guide bottom surface 706a and the opening lower edge 23C on the upstream side of the passage hole 23B of the first count switch 23a. (L12 <P). The depth dimension of the concave groove 725 to the bottom surface 725a is substantially the same as the width dimension L2 from the opening lower end edge 23C of the first count switch 23a to the lower long side of the main body 23A. Furthermore, the opening vertical width dimension L10 in the winning ball guiding path 706 formed by the upper and lower concave grooves 725 and 726 is larger than the diameter P of the game ball.

  Basically, since the diameter L1 of the passage hole 23B and the opening vertical width L10 in the winning ball guiding path 706 are formed to be substantially the same dimension (L10≈L1), the base body 702 and the first count switch 23a When a dimensional error occurs in the concave groove 725 or the main body 23A when the main body 23A is molded or assembled, a game ball formed between the upper end edge 23D of the passage hole 23B and the lower end edge 706b of the guide bottom surface 706a. There is a case where the actual opening vertical width L13 is shorter than the diameter P of the game ball (L13 <P).

  For example, as shown in FIG. 41A, the depth dimension of the concave groove 725 is longer (deeper) than the width dimension L2 from the opening lower end edge 23C of the first count switch 23a to the lower long side of the main body 23A. In such a case, the opening lower end edge 23C is disposed at a position lower than the downstream end edge 706b, and the opening upper end edge 23D approaches the guide bottom surface 706a, so that the opening vertical width dimension L13 is the game. It becomes shorter than the diameter P of the sphere, and the clogging of the sphere is likely to occur (L13 <P).

  As shown in FIG. 41 (b), the depth dimension of the groove 725 is shorter (shallow) than the width dimension L2 from the opening lower end edge 23C of the first count switch 23a to the lower long side of the main body 23A. ), The opening lower end edge 23C is disposed at a higher position than the downstream end edge 706b, and the opening upper end edge 23D moves away from the guiding bottom surface 706a, but the opening lower end edge 23C is guided. By projecting upward from the bottom surface 706a to form a step, the opening vertical width dimension L13 becomes shorter than the diameter P of the game ball, and ball clogging is likely to occur.

  Further, although not shown in particular, as described above, the diameter L1 of the passage hole 23B and the opening vertical width dimension L10 in the winning ball guiding path 706 are formed to be substantially the same dimension (L10≈L1). Even if such a dimensional error does not occur, if the relative position of the passage hole 23B with respect to the guide bottom surface 706a is slightly lowered due to, for example, dust attached to the game ball on the guide bottom surface 706a, FIG. Similarly to (b), the opening vertical width dimension L13 is shorter than the diameter P of the game ball, and it becomes easy for ball clogging to occur.

  On the other hand, as shown in FIG. 39 (b), the first count switch 23a of the present embodiment has the opening lower end edge 23C in the direction in which the game ball flows down with respect to the downstream end edge 706b of the guide bottom surface 706a. By providing the predetermined gap L12 apart, the opening vertical width dimension L13 becomes long, so that it becomes easier to ensure a longer width dimension than the diameter P of the game ball.

  Here, specifically, based on FIG. 40A, when the first count switch 23a is spaced apart in parallel toward the downstream side with respect to the guide bottom surface 706a, the opening vertical width dimension L13 is: By arranging the opening upper edge 23D at a position shifted to the downstream side, the imaginary line passing through the opening upper edge 23D and the downstream edge 706b becomes longer than the case where the imaginary line is orthogonal to the guide bottom surface 706a.

  Furthermore, as shown in FIG. 40B, when the first count switch 23a is spaced apart by tilting the upper part toward the downstream side with respect to the guide bottom surface 706a, the opening vertical width dimension L13 is By disposing the upper end edge 23D at a position shifted to the downstream side, the imaginary line passing through the upper end edge 23D of the opening and the downstream end edge portion 706b only becomes longer than when orthogonal to the guide bottom surface 706a. Since the opening lower end edge 23C is arranged at a position lower than the downstream end edge portion 706b, the game ball is guided to roll off from the downstream end edge portion 706b, and thus the game ball is smoothly moved. Can flow down.

  Further, since the first count switch 23a is installed in a state of being tilted in the downflow direction with respect to the guide bottom surface 706a, the downward tilt angle is larger when passing through the passage hole 23B than the guide bottom surface 706a. Therefore, even if there is a gap L12 between the guide bottom surface 706a and the passage hole 23B, the game ball can flow smoothly.

  As described above, in the pachinko gaming machine 1 as an embodiment of the present invention, a dimensional error occurs when the first special variable winning ball apparatus 23 is molded or assembled, or the game is formed on the guiding bottom surface 706a by use. Even if the relative position of the passage hole 23B with respect to the guide bottom surface 706a is slightly lowered due to adhesion of ball dust or the like, a gap L12 narrower than the diameter P of the game ball is formed between the guide bottom surface 706a and the passage hole 23B. By being provided, the opening vertical width L13 from the opening upper end edge 23D of the passage hole 23B to the downstream end edge 706b of the guide bottom surface 706a is increased, that is, the frontage is widened, so the vertical width dimension of the passage hole 23B is increased. It is prevented that the ball becomes narrow and clogging occurs.

  In addition, since at least the upstream edge of the passage hole 23B of the first count switch 23a is chamfered, the game ball can be moved even if there is a gap L12 between the guide bottom surface 706a and the passage hole 23B. It can be smoothly guided to the passage hole 23B.

  In the present embodiment, the first count switch 23a has a gap L12 narrower than the diameter P of the game ball between the guide bottom surface 706a and the passage hole 23B in a state where the first count switch 23a is erected in a direction intersecting the guide bottom surface 706a. Although it was installed so as to occur, to stand up in a direction intersecting with the guiding bottom surface 706a, for example, it is preferable to intersect with the guiding bottom surface 706a in a range of about 45 degrees to 90 degrees. Also, the gap L12 is preferably less than or equal to ½ of the diameter P of the game ball.

  In the present embodiment, the first count switch 23a is fitted in the concave groove 725. However, the first count switch 23a is not necessarily limited to the one installed in the concave groove 725. If it is installed between 707 and the guide bottom surface 706a, the installation structure can be variously modified.

  In the present embodiment, the first count switch 23a is installed on the left side of the first grand prize opening 23c and is provided so that the game ball is guided toward the left side, but the guidance bottom surface 706a is a game. As long as the ball is guided by rolling, the guiding (flowing) direction may be the rear side or the right side, and can be variously changed.

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

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