  In the embodiment, as shown in FIG. 9, the separation distance SL between the lower surface 162 of the flange 161 and the upper surface 124a of the open / close door 123 is about 12.5 mm, and the height protruding from the lower surface 162 of the guide rib 163 is high. The height dimension t1 is about 2.0 mm, and the height dimension t0 protruding from the lower surface 162 of the initial guide rib 166 is about 6.5 mm. Therefore, the height dimension H1 of the guide rib 163 in the orthogonal direction from the upper surface 124a of the open / close door 123 is about 10.5 mm, and the height dimension H0 of the guide rib 166 in the orthogonal direction from the upper surface 124a of the open / close door 123 is about 6. 0 mm.

  In the embodiment, as described above, the inclination angle θ0 of the left lower side of the upper surface 124a of the open / close door 123 is set to 10 ° together with the lower surface 162 of the flange portion 161. Further, the crossing angle θ1 intersecting the lowering direction of the upper surface 124a in the guide portion 164 of the guide rib 163 is 60 ° with respect to the lower surface 162 parallel to the upper surface 124a. Therefore, the guide ball 164 of the guide rib 163 turns the game ball B rolling to the left edge 123a side at an inclination angle θ0 of 10 ° obliquely backward or forward so that the upper surface 124a is lowered downward. The substantial lowering angle (rolling angle) θ2 of the rolling game ball B is relaxed to about 5.0 ° to reduce the rolling speed of the game ball B. Further, since the game ball B rolls to the left edge 123a side in a zigzag shape back and forth, the rolling distance of the game ball B that rolls obliquely on the upper surface 124a is also increased.

  The game ball B, which is guided by the guide part 164 and rolls on the upper surface 124a, is not guided by the guide part 164 and is rolled downward on the upper surface 124a according to the inclination angle θ0, compared to the distance Y. As Y / cos θ1 (30 °), that is, Y × 2, the rolling distance is doubled.

Further, as shown in FIG. 10, the descending angle θ2 is calculated by assuming that the rolling distance from the point a to the point b is Y and the height is Z according to the inclination angle θ0.
Z = Ysin θ0.
Further, the rolling distance that is guided from the point a to the point d by the guide part 164 by the intersection angle θ1 is Y / cos θ1, the height to be lowered is Z, and the descending angle is θ2 Because
(Y / cos θ1) × sin θ2 = Z.
for that reason,
Z = Ysin θ0 = (Y / cos θ1) × sin θ2,
sinθ2 = sinθ0 · cosθ1,
sinθ2 = (sin10 °) × (cos30 °), that is,
= (0.17365) × (0.5) = 0.086825.
Therefore, the descending angle θ2 is about 5.0 °.

  Further, the rolling state will be described in more detail. The guide portion 164 of the guide rib 163 of the embodiment has a height dimension H1 (SL) smaller than the diameter 11 mm of the game ball B with a height in the orthogonal direction from the upper surface 124a of the door 123. (12.5 mm) −t1 (2.0 mm) = 10.5 mm), and protrudes from the lower surface 162 of the flange portion 161. Therefore, the guide portion 164 comes into contact with the crown portion BC below the top apex BUT away from the upper surface 124a of the game ball B, in other words, the portion BC on the outer circumferential surface of the game ball B in the diagonally upward direction. Guide the sphere B. For example, as shown in FIG. 11, the game ball B that rolls while contacting the guide portion 164 of the guide rib 163F1 on the right edge side is counterclockwise as viewed from above due to the frictional resistance with the guide portion 164. The guide rib 163F1 moves from the base portion 163b of the guide rib 163F1 to the tip portion 163a, and then disengages from the tip portion 163a. The game ball B detached from the guide rib 163F1 is received by the guide portion 164 on the base portion 163b side of the guide rib 163B1 on the downstream side (left side when viewed from above) of the guide rib 163F1, and the frictional resistance with the guide portion 164 causes the game ball B to move upward. The guide rib 163B1 tries to move from the base portion 163b to the tip end portion 163a while rotating in the clockwise direction as viewed from above. And when rotating in this clockwise direction, it was rotating counterclockwise as viewed from above until just before that, so that the rotation stopped instantaneously, and through that state, the clockwise direction , While moving to the tip portion 163a side from the base portion 163b side. That is, in the embodiment, not only rolling on the upper surface 124a of the open / close door 123 in a zigzag shape, but also rotating in the clockwise direction and the counterclockwise direction alternately when viewed from above, the reverse rotation In doing so, the rolling speed of the game ball B is further reduced. Therefore, every time the guide ribs 163B1, 163F2, 163B2, and 163F3 move to the guide portions 164, the rotation is reversed, so the number of reverse rotations is increased, and in the embodiment, a more stable deceleration state is secured. ing.

  Therefore, if the game ball B rolls on the rolling path 148 through the right portion 148a and onto the upper surface 124a of the open / close door 123 at the closed position CP, a plurality of (eg, for example) game balls B are released before the left edge 123a is released. 4 or 5) can be rolled on the upper surface 124a of the door 123. Then, in a state where a plurality of game balls B are rolling on the upper surface 124 a of the open / close door 123, if the open / close door 123 moves to the open position OP, those game balls B win the big prize opening 121. it can.

  When the opening / closing door 123 retreats to the open position OP, the game ball B on the upper surface 124a of the opening / closing door 123 is not dragged by the opening / closing door 123 because the upper surface 124a is formed in a smooth flat shape. And, it is restricted by the vertical plate portion 156a of the back wall portion 156 between the open / close door 123 and the flange portion 161, and smoothly wins the big winning opening 121.

  In addition, the game ball B that has won the grand prize opening 121 enters the winning recess 147, and further rolls on the bottom surface portion 147a of the winning recess 147, and from the outlet 147c on the left corner side of the back surface portion 147b. It is discharged to a predetermined discharge trough (not shown). Note that a large winning opening SW150 for detecting the game ball B is disposed at the discharge port 147c.

  Further, in the flange portion 161 on the upper surface 124a of the opening / closing door 123, the separation distance SL from the upper surface 124a of the opening / closing door 123 is made larger than the diameter (11 mm) of the game ball B except for the portion of the guide rib 163 (about 12.5 mm), and the guide rib 163 protrudes from the lower surface 162 of the flange portion 161 with a height dimension t1 of about 2.0 mm. That is, the guide rib 163 has a height dimension H1 from the upper surface 124a of the opening / closing door 123 of 10.5 mm, and the vicinity of the upper apex BUT in the gaming ball B having a diameter of 11 mm that rolls on the upper surface 124a of the opening / closing door 123 is high. The game ball B can be rolled only by concealing about 0.5 mm of the dimension H2.

  Therefore, the player can visually recognize almost the entire upper and lower direction of the game ball B meandering in a zigzag manner and rolling, and can enjoy the game.

  Further, in the embodiment, the game ball B having a diameter of 11 mm that rolls on the upper surface 124a of the open / close door 123 interferes with the guide portion 164 in the vicinity of the top apex BUT by the height of H2 of 0.5 mm. Therefore, on the contrary, a portion that is 10.5 mm or less in height from the upper surface 124a is a portion that does not interfere with the guide portion 164. In other words, the interference area BCA of the height dimension H2 of 0.5 mm, that is, approximately 1/4 of the diameter, from the upper apex BUT in the direction orthogonal to the upper surface 124a of the open / close door 123 of the game ball B (FIG. 11). If it is on the outer peripheral side, see FIG. Therefore, as shown in FIG. 11, even if the tip end portion 163a of the guide ribs 163F and 163B is extended so as to enter above the rolling area of the game ball B on the upper surface 124a of the open / close door 123, The guiding action of the guiding portion 164 can be ensured, and even if the width dimension in the front-rear direction of the upper surface 124a of the open / close door 123 of the game ball B is small, the rolling can be smoothly performed with a long rolling distance and reduced by the guide rib 163. The game ball B can roll on the upper surface 124a depending on the speed.

  In the grand prize winning device 120, if the open / close door 123 is disposed at the open position OP and the big prize opening 121 is opened, the game ball B rolling on the right portion 148a of the rolling path 148 is obtained. Then, the ball enters the winning prize opening 121 and enters the winning recessed portion 147, and is further regulated by the left and right side portions 147d, 147d and the front wall portion 149 to roll on the bottom surface portion 147a of the winning recessed portion 147. Thus, it is discharged from the discharge port 147c on the left corner side in the back surface portion 147b.

  The front wall portion 149 covers the front side of the housing portion 145, and includes an upper portion 149a and a lower portion 149d. The upper part 149a includes a cover part 149b that covers the front edge side of the right part 148a of the rolling path 148 and a cover part 149c that covers the front side of the winning recess 147, and the lower part 149d covers the front side of the discharge port 147c. It is configured with.

(4) Description of gaming state, etc. The gaming state of the pachinko gaming machine 10 of the embodiment will be described. In the embodiment, as the gaming state to be set, a normal gaming state, a short-time gaming state, a probability variation gaming state, a latent certain gaming state, There are four game states. Also, in the pachinko gaming machine 10 of the embodiment, there are jackpot games (15R jackpot game and 2R jackpot game) and small hit games as games executed as a result of the special symbol lottery, which are executed as a result of the normal symbol lottery. There is an auxiliary game as a game. In the embodiment, the jackpot game is a special game advantageous to the player.

  The short-time gaming state means a state in which a game ball is more likely to win the second starting port 23 than in the normal gaming state. In the normal gaming state, for example, the winning probability of the normal symbol lottery is 1/20, and the normal symbol variation time It is 12 seconds, and as the opening pattern of the second starting port 23, a short opening pattern in which the opening for 0.2 seconds is performed once (at the time of winning the short opening pattern), and 4 after opening for 0.2 seconds. While there is a long opening pattern (when winning a long opening symbol) that releases 0 seconds, in the short-time gaming state, the winning probability of the normal symbol lottery is 19/20, and the normal symbol variation time is 0. It is 5 seconds, and as the opening pattern of the second start port 23, a short opening pattern that opens once for 3.0 seconds (when winning a short opening pattern), and a release of 5.0 seconds once There is a long open pattern (when winning a long open symbol) to perform. Short open symbols will be won on 2/11 at the time of winning, and long open symbols will be won on 9/11 at the time of winning. In addition, the winning probability of the normal symbol lottery during execution of the jackpot game, the normal symbol variation time, and the opening pattern of the second start port 23 are the same as in the normal gaming state, and the normal symbol lottery during execution of the small hit game The winning probability, the normal symbol variation time, and the opening pattern of the second start port 23 are the same as the gaming state at the time of winning the small hit.

  The probability variation gaming state is a state where it is easier to win a big hit than the normal gaming state, and a game ball is likely to win the second starting port 23. In the normal gaming state, for example, the probability of winning a big hit is 1/300. On the other hand, in the probability variation gaming state, the jackpot winning probability is 10/300. In the probability variation gaming state, the winning probability of the normal symbol lottery, the normal symbol variation time, and the opening pattern of the second start port 23 are the same as those in the short-time gaming state.

  The latent game state is a state where it is easier to win a big hit than the normal game state. In the latent game state, the jackpot winning probability is the same as the probability variable game state, and the normal symbol lottery winning probability, normal The symbol variation time and the opening pattern of the second start port 23 are the same as in the normal gaming state.

  In the initial state (that is, after the ram clear), the game state is a normal game state, and when winning a jackpot, the jackpot game is opened and closed a predetermined number of times, and the game state corresponding to the type of the jackpot is changed. To do. There are 2R (round) latent big hits as short hits where almost no prize balls can be expected, and 15R (round) probable big hits, 15R (round). ) There is usually a jackpot. In addition to these jackpots, there is a jackpot. In addition, a round means the open period of the grand prize opening 121. Then, in the 2R latent big hit, after performing a big hit game in which the round winning opening 121 is opened, for example, for a very short time of 0.3 seconds, the big winning opening 121 between rounds is closed. For example, the interval time is 0.5 seconds). In the 15R probability variation jackpot, for example, after performing a jackpot game in which a round that opens 29.5 seconds per round is played 15 times (for example, the interval time during which the big prize mouth 121 is closed between rounds is (For example, 1.5 seconds), after transitioning to a probabilistic gaming state, with 15R normal jackpot, after performing a jackpot game in which 15 rounds are opened, for example, 29.5 seconds each time (The interval time during which the big prize opening 121 between rounds is closed is, for example, 1.5 seconds), and transition to the short-time gaming state. In addition, the small hit is an operation that does not seem to be different from the 2R latent big hit, and a small hit game in which the big winning opening 121 is opened twice in a very short time is performed, but the game state does not change. It should be noted that even if a special symbol change is performed 100 times without causing a big hit in the middle of the short-time gaming state, a transition to the normal gaming state is made.

  The lottery for the jackpot and the jackpot is performed using the jackpot random number, and when the jackpot is won, the lottery for which type of jackpot is the jackpot is performed using the jackpot symbol random number. The jackpot random number is, for example, a value in the range of 0 to 299. In the normal gaming state or the short-time gaming state, the random number value won in the jackpot so that the ratio of winning in the jackpot is 1/300. In addition to being determined, a random value for winning a small hit is determined so that the ratio of winning a small win is 3/300. In the jackpot random number, a random number value for winning the jackpot is determined so that the winning ratio for winning the jackpot is 10/300 in the probability variation gaming state or the latent probability gaming state, and the ratio for winning the jackpot is 3 A random number value to be won on a small hit is determined so as to be / 300. The jackpot symbol random number takes a value in the range of, for example, 0 to 249. For winning to the first starting port 22, the ratio of winning the 15R normal jackpot is 100/250, and the 15R probability variable jackpot The random number value for each jackpot is determined so that the winning ratio is 75/250 and the winning ratio for 2R latent chance is 75/250. Random numbers to be won for each jackpot are determined so that the ratio to win the normal jackpot is 100/250, the ratio to win the 15R probability variation jackpot is 125/250, and the ratio to win the 2R latent jackpot is 25/250. The ratio of winning per long is higher than when winning the first starting port 22. That is, in the pachinko gaming machine 10 of the embodiment, the big hit lottery performed with the game ball entering the second start port 23 is more than the big hit lottery performed with the game ball winning the first start port 22. It is set to be advantageous to the player.

  Also, when the result of the jackpot lottery is a loss, whether or not the decorative symbol is set to the reach state in the decorative symbol variation effect performed in parallel with the special symbol variation is performed using a reach random number. The reach random number is assumed to take a value in the range of 0 to 249, for example, and the winning ratio is 40/250 with reach, that is, reach state, and is won without reach, ie, not reach state. The random number value to be won in the reach is determined so that the ratio to be achieved is 210/250.

  In addition, a lottery for determining whether or not to perform an auxiliary game, that is, a normal symbol lottery is performed using a random number, and if a winner is won, a lottery to determine which type of winning will be the winning symbol This is done using random numbers. For example, the winning random number takes a value in the range of 0 to 19, and in the non-specific gaming state (the normal gaming state, the latent gaming state, and the jackpot game are being executed), the winning percentage is 1 A random number value to be won is determined to be / 20, and in a specific gaming state (short-time gaming state and probability variable gaming state), a random number value to be won is determined so that the winning ratio is 19/20 ing. In addition, the winning symbol random number takes a value in the range of, for example, 0 to 10, so that the ratio of winning the short opening symbol is 2/11 and the ratio of winning the long opening symbol is 9/11. A random number value to be won for each is determined. If the result of the normal symbol lottery is a loss, the winning symbol random number is determined to be a loss.

(5) Operation of pachinko machines <Processing in the main control unit>
Next, the operation of the main control unit 60 will be described based on FIGS. Each counter, which will be described later, is provided in the RAM 63 and cleared to zero when the pachinko gaming machine 10 is powered on.

  When the supply of power is started, the main control unit 60 starts executing main control processing including a start-up process and a power shut-off monitoring process (not shown). During the supply of power to the main control unit 60, the main control unit 60 Control processing is executed continuously. And the main control part 60 interrupts and performs the timer interruption process shown in FIG. 13 for every predetermined period (for example, every 4 ms) with respect to this main control process.

[Main-side timer interrupt processing]
The main control unit 60 repeats the main-side timer interrupt process shown in FIG. 13 every short time such as 4 msec. That is, random number update processing (S201), start port SW processing (S202), gate SW processing (S203), big prize opening SW processing (S204), normal winning opening SW processing (S205), special symbol processing (S206), normal The symbol process (S207), the big prize opening process (S208), the electric chew process (S209), the prize ball process (S210), and the output process (S211) are repeated.

  [Random number update process] In the random number update process (S201), although not shown, the main control unit 60 selects the jackpot random number and jackpot symbol type (15R normal symbol, 15R probability variation symbol, or 2R latent probability symbol) used for the jackpot lottery. Jackpot symbol random number to determine, reach random number to determine whether or not to reach reach in decorative symbol variation effect, variation to determine variation pattern of decoration symbol variation effect (for example, whether to perform super reach effect or pseudo-ream) A random number update process is performed to update the pattern random number, the random number used for the normal symbol lottery, and the winning symbol random number for determining the type of the winning symbol (long open symbol, short open symbol, or lost symbol).

[Start-up SW processing]
In the start port SW process (S202), as shown in FIG. 14, the main control unit 60 determines whether or not the first start port SW22a is turned on (S301). If not, the process proceeds to step S306. If it is ON, it is determined whether or not the value U1 of the first start port hold counter for counting the number of jackpot random numbers stored in the first special figure hold storage unit 63a is less than the upper limit of 4 (S302). . If it is not less than 4, the process proceeds to step S306. If it is less than 4, 1 is added to U1 (S303), and various random numbers (big hit random number, big hit symbol random number, reach random number, variation pattern random number) are acquired and the first special feature is obtained. It is stored in the figure holding storage unit 63a (S304). Then, the first hold number increase command is set (S305), and the process proceeds to step S306.

  In step S306, the main control unit 60 determines whether or not the second start port SW23a is turned on. If not, the main control unit 60 finishes the start port SW process. If it is turned on, the second special figure storage unit 63b. It is determined whether or not the value U2 of the second start-port hold counter that counts the number of jackpot random numbers stored in is less than the upper limit of 4 (S307). If it is not less than 4, the start-up SW processing is finished. If it is less than 4, 1 is added to U2 (S308), and various random numbers (big hit random number, big hit symbol random number, reach random number, fluctuation pattern random number) are obtained and 2 is stored in the special figure storage unit 63b (S309). Then, the second hold number increase command is set (S310), and the start port SW process is completed.

  [Gate Processing] In the gate processing (S203), although not shown, when the main control unit 60 determines that the gate SW 28a has been turned on, a normal random number is obtained on condition that the number of normal symbol reserved balls is less than “4”. Acquire and store.

  [Big Winner SW Processing] Although not shown in the big win SW SW processing (S204), if the big win SW27a is ON, whether the big win game or the small win game (the win game flag described later is ON)? If it is determined whether or not the game is in the big win game or the small hit game, 1 is added to the value of the winning prize counter and 1 is added to the value of the big winning counter.

  [Normal Winning Port SW Processing] Although not shown, the normal winning port SW processing (S205) is a process of adding 1 to the value of the normal winning port counter if the normal winning port SW30a is ON.

  Subsequently, the main control unit 60 performs a special symbol process (S206), a normal symbol process (S207), which will be described later, a big prize opening process (S208), an electric chew process (S209), a prize ball process (S210), which are described later, The output process (S211) is performed.

  [Normal symbol processing] In the normal symbol processing (S207), although not shown, the winning random number stored in the gate SW processing is the current gaming state (probability changing gaming state, normal gaming state, latent certain gaming state or short-time gaming state). It is determined whether it is a hit random number value or a lost random value set in advance corresponding to the game, and the normal symbol change time is selected according to the current gaming state, and the normal symbol display 37 is selected. When the normal symbol is variably displayed only for the variation time, and when the variation time has elapsed and the variation display of the normal symbol is stopped, the auxiliary game flag is turned on when the winning random number is the winning random number value. When the auxiliary game flag is turned on, in the electric chew process (S209), the electric chew 24 is opened for the open time and the number of times set according to the current game state.

  [Electric Chu Processing] In the electric chewing processing (S209), although not shown, when the auxiliary game flag is turned on in the above-described normal symbol processing, the electric chew 24 of the second starting port 23 is set according to the current gaming state. Opening operation is performed for the opening time and number of times.

  [Prize Ball Processing] In the prize ball processing (S210), although not shown, the number of prize balls (15 balls per count in the embodiment) according to the value of the big prize counter corresponding to the game ball entry, The number of prize balls according to the value of the normal prize opening counter (10 balls per count in the embodiment) and the number of prize balls according to the value of the start prize mouth counter (3 balls per count in the embodiment) Set a command to issue, and clear those counters to zero.

  [Output Process] In the output process (S211), although not shown, various commands are output to the payout control unit 70 and the effect control unit 90.

[Special symbol processing]
In the special symbol process (S206), as shown in FIG. 15, the main control unit 60 performs a winning game flag indicating whether or not a winning game is being played (that is, a small winning game flag, a long winning game flag, or a short winning game). It is determined whether or not the flag) is ON (S401). If the flag is ON, the special symbol processing is terminated. If it is not ON, it is determined whether or not the special symbol is changing (S402). If it is changing, the process proceeds to step S411. If it is not changing, it is determined whether or not the value U2 of the second start port hold counter or the value U1 of the first start port hold counter is 1 or more (S403, S405). ). If U2 and U1 are not 1 or more, the special symbol processing is finished. If U2 or U1 is 1 or more, 1 is subtracted from U2 or U1 (S404, S406) and stored in step S304 or S309. A jackpot determination process (S407), which will be described later, is performed using the jackpot random number, and then a variation pattern selection process, which will be described later, is performed (S408).

  Thereafter, the main control unit 60 starts the variation of the special symbol in the first special symbol display 39a or the second special symbol display 39b (S409), sets a variation start command (S410), and proceeds to step S411. . In step S411, it is determined whether or not the variation time of the special symbol has elapsed. If it has not elapsed, the special symbol processing is terminated, but if it has elapsed, the variation of the special symbol is stopped and set in the jackpot determination processing. The special symbol is fixedly displayed with the symbol that has been displayed (S412), and a variable stop command is set (S413). Then, a stop process (S414) described later is performed, and the special symbol process is completed.

[Big hit judgment processing]
In the jackpot determination process (S407), as shown in FIG. 16, the main control unit 60 determines whether or not the jackpot random number is a jackpot using the jackpot determination table corresponding to the gaming state (S501). If it is a big hit (YES in S502), it is determined which jackpot symbol the jackpot symbol random number stored in step S304 or S309 indicates (S503), and the jackpot symbol is set (S504). . The type of jackpot is determined by the jackpot design. On the other hand, if the jackpot random number is not a jackpot (NO in S502), but if it is a jackpot (YES in S505), a jackpot symbol is set (S506). If it is not a small hit (NO in S505), a lost pattern is set (S507).

[Variation pattern selection processing]
In the variation pattern selection process (S408), as shown in FIG. 17, if the main control unit 60 determines that it is a big hit in the previous jackpot determination process (see FIGS. 15 and 16) (YES in S601), the variation pattern. A big hit table is set as a table (S602), and if it is determined that a small hit is made (NO in S601, YES in S603), a small hit table is set as a variation pattern table (S604). If neither big win nor small win (NO in S603), the reach random number determination table is referred to determine whether the reach random number stored in step S304 or S309 indicates the presence of reach. (S605) If the reach is present (YES in S606), the reach loss table is set as the variation pattern table (S607). If the reach is not present (NO in S606), the loose table is used as the variation pattern table. Set (S608). Here, the loose rose refers to a variation pattern in which a decorative design is stopped and displayed without reaching a reach state. The reach state of the decorative symbol means a state in which two of the three decorative symbols and the left decorative symbol, the middle decorative symbol, and the right decorative symbol are stopped and displayed with the same decorative symbol. Each decorative design is composed of, for example, a design decorated with numbers from “1” to “9”.

  Next, the main control unit 60 refers to the variation pattern table set as described above, and determines which variation pattern the variation pattern random number stored in step S304 or step S309 indicates ( S609), the variation pattern indicated by the variation pattern random number is set (S610). Note that the variation pattern includes information indicating the variation time. In addition, the variation pattern random number takes a value from 0 to 10363, for example, whether the result of the big hit lottery is a big hit, a small hit or a loss, and if it is a big hit, what is the type of the big hit symbol? In the case of losing, the random number is determined by referring to a variation pattern table that differs depending on whether it is reach loss or rose loss, and is a random number for determining one variation pattern from about 180 variation patterns.

[Processing while stopped]
In the stop process (S414), as shown in FIG. 18, the main control unit 60 determines whether or not the short-time game flag indicating whether or not the short-time game state is ON (S701). If it is ON, the value J of the hour fluctuation counter that counts the number of fluctuations of the special symbol in the hourly gaming state is decremented by 1 (S702). If J is 0, the hourly gaming is ended to end the hourly gaming state. The flag is turned off (S703, S704), and the process proceeds to step S705.

  In step S705, the main control unit 60 determines whether or not the probability variation game flag indicating whether or not the probability variation game state or the latent probability game flag indicating whether or not the latent probability game state is ON (S705). The process proceeds to step S709, but if it is ON, the value X of the probability variation latent probability variation counter for counting the number of variations of the special symbol in the probability variation gaming state or the latent probability gaming state is subtracted by 1 (S706). If there is, the probability variation / latency game flag is turned OFF to end the probability variation game state or the latent probability game state (S707, S708), and the process proceeds to step S709.

  In step S709, the main control unit 60 determines whether or not the jackpot is big (that is, whether or not the stopped special symbol is a jackpot symbol). If the jackpot is a big jackpot (YES in S709), the jackpot is a jackpot. It is determined whether or not (S710). If it is per long, a game flag per long is set (S711). If not per long, it is a short win, so a short hit flag is set (S712). Then, the time variation counter value J and the probability variation latent probability variation counter value X are cleared to zero (S713), the time variation game flag, the probability variation game flag, and the latent probability game flag are turned OFF (S714), and the process proceeds to step S717.

  On the other hand, if it is not a big hit (NO in S709), the main control unit 60 determines whether or not it is a small hit (that is, whether or not the stopped special symbol is a small hit symbol) (S715). Finishes the stop process, and if it is a small hit, the small hit game flag is turned on (S716), and the process proceeds to step S717.

  In step S717, the main control unit 60 starts the winning game (big hit game or small hit game) (S717), sets an opening command (S718), and finishes the in-stop process.

[Large winning prize processing]
In the big prize opening process (S208), as shown in FIG. 19, the main control unit 60 first determines whether or not the winning game flag is ON (S801). If it is ON, it is determined whether or not opening is in progress (S802). The opening refers to the period from the start of the winning game to the start of the first round. When it is determined that the opening is in progress, the main control unit 60 determines whether or not the opening time has elapsed (S803). A maximum R number (round number) and an operation pattern according to the type are set (S804). Then, the value C of the winning number counter is cleared to zero (S805), 1 is added to the value R of the round counter (S806), and the opening of the big winning opening 121 is started (S807).

  Next, the main control unit 60 determines whether or not the opening time of the grand prize winning port 121 (in the embodiment, 29.5 seconds for long wins, 0.3 seconds for short wins or small wins) has elapsed. (S808), if it has elapsed, the big prize opening 121 is closed (S810), and if it has not elapsed, the value C of the winning number counter is a prescribed number (9 in the embodiment) or not. If the number is not the specified number, the big prize opening process is finished, and if the number is the prescribed number, the big prize opening 121 is closed (S810).

  Then, the main control unit 60 determines whether or not the value R of the round counter is the maximum number of Rs (S811). If it is not the maximum number of Rs, the big prize opening process is finished. Is started (S812), an ending command is set (S813), and the value R of the round counter is cleared to zero (S814). Ending refers to the period from the end of the final round to the end of the winning game. Next, the main control unit 60 determines whether or not the ending time has elapsed (S819), and if it has not elapsed, finishes the big prize opening process, and if it has elapsed, performs a game state setting process to be described later. (S820), the winning game flag is turned OFF (S821).

  On the other hand, when determining that the opening is not in progress in step S802, the main control unit 60 determines whether or not the special winning opening 121 is in the ending (S815), and if it is in the ending, the process proceeds to step S819. If it is not in the ending, it is determined whether or not it is in the interval (S816). If it is not in the interval, the process proceeds to step S818. If it is in the interval, the interval time (in the embodiment, 1 per length) .5 seconds, 0.5 seconds if short win or small win) has passed (S817). If it has not passed, the big prize opening process is finished, and if it has passed, The process proceeds to step S818. In step S818, it is determined whether or not the special winning opening 121 is being opened. If it is not opened, the process proceeds to step S805, and if it is opened, the process proceeds to step S808.

[Game state setting process]
In the game state setting process (S818), as shown in FIG. 20, if the winning game to be ended is a small hit (YES in S901), the main control unit 60 does not change the game state, so the game state setting process is performed. If it is finished and 15R is a normal jackpot (YES in S902), the short-time game flag is turned ON to make transition to the short-time game state (S903), and the value J of the short-time fluctuation counter is set to 100 (S904), and the game state setting process is performed. Finish. Further, if the winning game to be ended is 15R probability variation big hit (YES in S905), the probability variation game flag is turned ON to make a transition to the probability variation game state (S906), and the value X of the probability variation latent probability variation counter is set to 10000 ( S908), the game state setting process is finished, and if the 2R latent probability is a big hit (NO in S905), the latent probability game flag is turned on to make a transition to the latent probability gaming state (S907), and the value of the probability variation latent probability variation counter is set. X is set to 10000 (S908), and the game state setting process ends.

≪Processing in sub-control unit≫
In parallel with the processing in the main control unit 60 described above, in the effect control unit 90 of the sub control unit 85, the hold increase command, the change start command, the change pattern command, the change stop command, and the winning game transmitted from the main control unit 60. In response to the opening and ending commands, customer waiting commands, etc., the corresponding decorative symbol variation effect, jackpot effect, customer waiting effect, etc. are controlled while controlling the image sound control unit 95 and the lamp control unit 100. An effect is displayed on the display screen 20a of the display unit 20, a predetermined sound is appropriately output from the speaker 48, the lamps 49 and 50 are turned on, and the movable accessory device 110 is operated to perform a predetermined operation. Will be performed. In addition, the operation of the effect button 46 and the effect key 47 is urged as appropriate, and in accordance with those operations, the corresponding effects are displayed on the display screen 20a of the image display unit 20, the speaker 48, the lamps 49 and 50, and the movable accessory. One or more of the devices 110 will be used for execution.

(4) Actions and effects of the pachinko gaming machine of the embodiment
As shown in FIGS. 1 and 2, the pachinko gaming machine 10 according to the embodiment has an open / close door 123 that allows a game ball B that rolls in the game area 16 to flow down when it is opened and can be awarded, and cannot be awarded when it is closed. A game machine equipped with a special prize device 120 as a special prize device, in which an opening / closing door 123 is disposed with an inclined upper surface 124a, and the game ball B rolling on the upper surface 124a of the opening / closing door 123 can be decelerated. The speed reduction part 160 is disposed and configured on at least one (above in the embodiment) above or below the game ball B rolling on the opening / closing door 123.

  Therefore, for example, during the jackpot game per long, an interval between rounds in the middle of hitting the right side 16a of the game area 16 and hitting the game ball B so as to win the open big prize opening 121 At that time, it is assumed that the open / close door 123 once closes the special winning opening 121. At that time, a plurality of game balls B sequentially enter the upper surface 124a of the door 123 through the right edge 148a of the rolling path 148 and the right edge 123b of the door 123 that closes the grand prize opening 121. May come. However, these game balls B roll from the right edge 123b side of the open / close door 123 to the left edge 123a side in response to the inclination of the inclination angle θ0, and are not released immediately but are rotated by the speed reduction unit 160. Since the moving speed is decelerated, a plurality of pieces are put on the upper surface 124a of the open / close door 123 from the left edge 123a side to the right edge 123b side at the same time while rolling.

  In such a state, if the interval time elapses, YES in S816 of the winning prize processing (S208, see FIG. 19), YES in S817, YES in S818, NO → S805 → S807, and the next winning prize 121 in the next land. Is released. That is, the large winning opening solenoid 130 of the drive mechanism 128 is turned ON, and the opening / closing door 123 moves backward to the open position OP so as to open the large winning opening 121 as shown in FIG. . Then, the plurality of game balls B placed on the upper surface 124 a of the open / close door 123 fall and win the big winning opening 121.

  Therefore, in the pachinko gaming machine 10 according to the embodiment, all of the game balls B placed on the upper surface 124a of the open / close door 123 at the start of the opening of the next prize winning opening 121 after the interval are awarded to the prize winning opening 121. Therefore, it is possible to reduce the number of spilled balls and win a plurality of game balls B in the big hit game.

  Of course, in the embodiment, the game can be suitably performed not only at the interval between rounds in the jackpot game per long. That is, in the short-time gaming state and the probability-changing gaming state, the player hits the right side 16a of the gaming area 16 and hits the right side of the gaming area 16 with the aim of entering the gate 28 and the second starting port 23. And at that time, there may be a case where a small hit is won, and even during the small hit game, a plurality of game balls that have been hit to the right can be placed on the upper surface 124a of the open / close door 123 before opening, In this state, if the door 123 is opened by a small hit, even if the opening time is as short as 0.3 seconds, a plurality of prizes can be won, and the player can play happily, Can be improved. That is, in the embodiment, not only during the big hit game for opening and closing the door 123, but also during the small hit game for opening and closing the door 123, it is possible to reduce the number of spilled balls and win a plurality of game balls B. it can.

2.
In the pachinko gaming machine 10 according to the embodiment, the speed reducing portion 160 that can decelerate the game ball B rolling on the upper surface 124 a of the opening / closing door 123 is disposed above the upper surface 124 a of the opening / closing door 123 when the prize winning opening 121 is closed. Has been.

  In other words, the speed reduction part 160 is disposed above the door 123, and the speed reduction part 160 is simply disposed above the door 123 without changing the configuration of the door 123 and the special winning opening 121. That is, it is possible to configure the large winning device 120 as a special winning device that can easily win a plurality of game balls B by reducing the spilled balls by simply attaching the speed reducing unit 160 separately.

3.
In the embodiment, the speed reducing unit 160 rolls so that the game ball B rolling on the upper surface 124 a of the opening / closing door 123 meanders in a zigzag manner on the lower surface 162 of the flange portion 161 disposed above the opening / closing door 123. The guide rib 163 to be projected is configured to project downward.

  Therefore, the game ball B rolling on the upper surface 124a of the open / close door 123 rolls so as to meander in a zigzag manner with a substantial rolling distance and a low rolling speed. In the embodiment, a plurality of game balls B can be easily placed on the open / close door 123 at the same time.

  Even if the guide rib 163 protrudes downward, the open / close door 123 that opens and closes the winning prize opening 121 is configured to advance and retreat back and forth, and the upper surface 124a has a smooth flat surface, and thus the upper surface 124a. However, even if it is in contact with the game ball B interfering with the guide rib 163, the open / close door 123 can be smoothly retracted to the open position OP.

4).
In the embodiment, the guide rib 163 constituting the speed reducing portion 160 includes a guide rib 163F (163F1, 163F2, 163F3) extending from the front edge 162a side of the lower surface 162 of the flange portion 161 toward the center 162c side in the front-rear direction, and a rear edge 162b. Guide rib 163B (163B1, 163B2) extending from the side to the center 162c side in the front-rear direction, and a guide portion that guides the lower right side (corner portion) of each right side in contact with the game ball B 164. These guide portions 164 are linear with an intersecting angle (an angle deviating from the left-right direction in the embodiment to the front-rear direction in the embodiment) θ1 intersecting with an inclination direction (left direction in the embodiment) in which the door 123 is lowered. It is said.

  Therefore, the rolling distance and rolling speed of the game ball B can be easily adjusted by adjusting the intersection angle θ1 of the guide portion 164. That is, if the intersection angle θ1 is reduced, the rate of increasing the rolling distance is reduced, the rate of reducing the rolling speed is also reduced, and conversely, if the intersection angle θ1 is increased, the rate of increasing the rolling distance. Can be increased, and the rate at which the rolling speed is reduced can also be increased. If the intersecting angle θ1 is too large, the substantial descending angle θ2 of the game ball B that is guided and rolled by the guide portion 164 becomes too small, and the game ball B may not roll. That is, when the descending angle θ2 is less than 4 °, the game ball B is difficult to roll. Therefore, for example, if the opening / closing door 123 has the inclination angle θ0 of about 10 °, the intersection angle θ1 should be about 67 °. Is the limit. Therefore, the intersection angle θ1 is preferably within a range of 45 to 67 ° if the inclination angle θ0 of the opening / closing door 123 is about 10 °.

5.
Furthermore, in the embodiment, the guide rib 163 includes a guide rib 163F (163F1, 163F2, 163F3) that extends from the front edge 162a side of the lower surface 162 of the flange portion 161 toward the center 162c side in the front-rear direction, and the front-rear direction from the rear edge 162b side. As the two types of guide ribs 163B (163B1, 163B2) extending to the center 162c side, a plurality of them are respectively configured.

  Therefore, the game ball B not only rolls on the upper surface 124a of the open / close door 123 in a zigzag manner, but also alternately rotates counterclockwise and clockwise as viewed from above. At the time of reverse rotation, the state is once reset, and the average rolling speed of the game balls B passing through the entire region from the right edge 123b to the left edge 123a of the open / close door 123 is further reduced. Furthermore, in the embodiment, every time the guide ribs 163B1, 163F2, 163B2, and 163F3 are shifted to the guide portions 164, the rotation is reversed, so that the number of reverse rotations is increased, and a more stable deceleration state can be secured. .

6).
In the embodiment, the guide rib 163 in the flange 161 above the upper surface 124a of the open / close door 123 has a height dimension H1 from the upper surface 124a of 10.5 mm and rolls on the upper surface 124a of the open / close door 123 with a diameter of 11 mm. Since the game ball B can be rolled simply by concealing the vicinity of the top apex BUT of the ball B by a 0.5 mm dimension having a height dimension H2, the player rolls in a zigzag manner. The entire area of the game ball B in the vertical direction can be visually recognized, and the game can be enjoyed.

7).
Further, in the embodiment, the guide rib 163 in the flange 161 above the upper surface 124a of the open / close door 123 has a height dimension H1 from the upper surface 124a of 10.5 mm, and rolls on the upper surface 124a of the open / close door 123 with a diameter of 11 mm. Since the game ball B is rolled only by concealing the vicinity of the top apex BUT of the game ball B of 0.5 mm by the height dimension H2, it is approximately ¼ of the diameter dimension when viewed from above. If it is on the outer peripheral side from the interference area BCA, the guide portion 164 does not interfere with the guide portion 164 of the front and rear guide ribs 163F, 163B, the game ball B is the vertical plate portion 156a of the back wall portion 156, Until just before the position of the glass portion 14a is restricted, it can be extended so as to enter above the rolling area of the game ball B on the upper surface 124a of the door 123. Therefore, even if the width dimension in the front-rear direction of the upper surface 124a of the open / close door 123 of the game ball B is small, the game ball B is smoothly moved by the guide rib 163 with a long rolling distance and a reduced rolling speed. It can be rolled on 124a.

  In addition, although such an action and effect can extend the front-end | tip part 163a long if the interference area BCA which the guide part 164 of the guide rib 163 contacts approaches the upper top part BUT of the game ball B, at the time of rolling If the interference area BCA where the guide portion 164 of the guide rib 163 contacts is away from the top apex BUT of the game ball B, conversely, the contact with the game ball B during rolling is reduced. Although the distance becomes long, the tip portion 163a cannot be extended long. Therefore, it is desirable to dispose the guide rib 163 as the interference area BCA having the height dimension H2 of about 2.5 to 0.2 mm.

8).
In the embodiment, the case where the guide rib 163 having the inclined linear guide portion 164 is provided on the lower surface 162 of the flange portion 161 as the speed reduction portion 160 provided above the upper surface 124a of the open / close door 123 is shown. However, as the speed reducing portion, it is only necessary that the game ball B rolling on the upper surface 124a of the open / close door 123 is decelerated and the time and distance on the upper surface 124a are increased. Therefore, for example, as shown in FIG. 21, a guide rib 163 provided with a substantially hemispherical guide part 164A is provided on the lower surface 162 as the speed reducing part 160A, and the game ball B is arranged along the curve of the guide part 164A. It is good also as a structure to bend and roll. 22 and 23, elastic deformation portions 165 such as a brush 164B and a rubber piece 164C which are bent at the time of contact with the game ball B are provided on the lower surface 162 so as to project the game ball B. You may comprise so that the game ball | bowl B may be decelerated at the time of contact with the elastic deformation part 165.

In the embodiment, the configuration of moving back and forth is exemplified as the operation when opening / closing the big prize opening 121 in the opening / closing door 123, but as the opening / closing door 123D shown in FIG. It is good also as composition to do.

  In this way, in the open / close door 123D that rotates downward when the grand prize opening 121 is opened, the guide ribs are formed on the upper surface 124a of the game ball B when the special prize opening 121 is closed, as shown by a two-dot chain line in FIG. Even if 163 is provided, the special winning opening 121 can be easily opened. Therefore, the speed reduction part 160D may be configured by providing a guide rib 163 or the like below the game ball B rolling on the opening / closing door 123D.

  Of course, even if the opening / closing door 123 moves back and forth, it rolls to the upper surface 124a side if it can be smoothly retracted from the lower side of the game ball to the open position without giving unnecessary movement to the game ball when opened. You may provide a deceleration part so that the rolling speed of a game ball can be decelerated. As such a speed reduction part, a speed reduction part provided with unevenness that interferes with the game ball so as to reduce the rolling speed, a speed reduction part having elasticity that sinks slightly so as not to roll quickly, or An example is a speed reduction portion having such an adhesive that a rolling game ball is adsorbed.

10.
Furthermore, as a modified example, the big winning device 120E shown in FIGS. 25 to 30 may be used so as to extend the rolling distance of the game ball B. The large winning device 120E is configured such that the main body portion 124E of the open / close door 123E extends rearward from the large winning port 121 and includes an engagement hole 126. And the lower surface 162 of the collar part 161E which comprises the deceleration part 160E is comprised so that it may extend to the upper direction of the main-body part 124E extended backward.

  Further, the rear wall portion 156E of the housing portion 145E has a vertical plate portion 156a disposed in the vicinity of the rear edge of the engagement hole 126 in the main body portion 124E of the opening / closing door 123E, so Side walls 156g and 156h extending from the edge to the vertical plate 156a on the rear side are provided.

  A plurality of prismatic guide ribs 169 constituting the speed reducing portion 160E are disposed on the lower surface 162 of the flange portion 161E. The guide rib 169 includes a guide rib 169F extending rearward from the front edge 162a side of the lower surface 162 of the flange portion 161E, A guide rib 169B extending forward from the rear edge 162b side, and the lower edge side (corner portion) of the right edge is in contact with the crown portion BC of the game ball B so that the game ball B is opened and closed in an inclined manner. The guide part 170 is configured to roll at a lowering angle (rolling angle) that is gentler than the door 123E.

  The inclination angle θ0 of the upper surface 124a of the open / close door 123E is 10 °, the crossing angle θ1 with respect to the left-right direction of the guide portion 170 is 60 °, and the game ball B is placed on the upper surface of the open / close door 123E in the same manner as the guide rib 163. On 124a, rolling is performed at a lowering angle that is gentler than the inclination angle θ0. However, in this grand prize winning device 120E, the rolling distance of the game ball B rolling on the upper surface 124a of the main body part 124E is increased by the extent that the main body part 124E and the guide rib 163E of the open / close door 123E extend rearward.

  The open / close door 123E is opened / closed by swinging the engagement piece 142 of the open / close lever 139 inserted into the engagement hole 126 back and forth by a predetermined drive mechanism 128, as in the prize winning device 120. .

  The rolling state of the game ball B in the big winning device 120E will be described. When the game ball B enters the upper surface 124a of the open / close door 123E from the right edge 123b through the right portion 148a of the rolling path 148, the game ball B rolls the upper surface 124a while rotating the ball crown portion BC on the top apex BUT side to the base portion 169b of the guide portion 170 of the guide rib 169F1 and rotating to the tip portion 169a side. When the interference area BCA is detached from the tip portion 169a, the game ball B brings the ball crown portion BC on the upper top BUT side into contact with the guide portion 170 side on the base portion 169b side of the guide rib 169B1. Then, the game ball B rolls on the upper surface 124a while rotating from the base portion 169b side to the tip end portion 169a side by bringing the top crown BUT side crown portion BC into contact with the guide portion 170 of the guide rib 169B1. Hereinafter, when the guide ribs 169F2 and 169B2 are sequentially moved and separated from the tip end portion 169a of the guide rib 169B2, the rolling is performed to the left portion 148b side of the rolling path 148.

  Of course, also in this special prize winning device 120E, the game ball B reverses the direction of rotation when it is detached from the tip end portion 169a of the guide rib 169 and rotates in contact with the guide portion 170 of the next guide rib 169. Therefore, similar to the big winning device 120, the game ball B not only rolls on the upper surface 124a of the open / close door 123E in a zigzag shape, but also in the clockwise direction and the counterclockwise direction as viewed from above. Since the rotation is alternately performed, when the vehicle is reversely rotated, the state is temporarily reset, and the average rolling speed of the game ball B passing through the entire region from the right edge 123b to the left edge 123a of the open / close door 123E is reduced. Furthermore, the number of times of reverse rotation can be secured multiple times as three times when moving from the guide rib 169F1 to the guide rib 169B1, the guide rib 169B1 to the guide rib 169F2, and the guide rib 169F2 to the guide rib 169B2. A stable deceleration state can be secured.

  When the opening / closing door 123E is closed, the game ball B rolls on the upper surface 124a while being guided by the guide portion 170 of the guide rib 169 as described above, and when the opening / closing door 123E is opened, the winning prize port 121 is played. On the other hand, if it flows down directly or deviates from the top of the big prize opening 121 to the rear, it is guided on the upper surface 124a of the open / close door 123E by the inclined guide part 170 of the guide rib 169, and the big prize opening 121 is obtained. Will roll to the side and then flow down to the big prize opening 121 side. Therefore, even in the big winning device 120E, when the big winning opening 121 is opened, all of the game balls B placed on the upper surface 124a of the open / close door 123E can be won into the big winning opening 121. By reducing the number of spilled balls, a plurality of game balls B can be won.
