When discharged outside Detecting unit for detecting the passage of the monitor the game ball (e.g., a magnetic switch) and a right pay detecting means 47 having a.

Next, the operation of the winning device configured as described above will be described.
(1) When not operating (Figs. 3, 5, 7, 10)
When the winning device 100 is in an inoperative state, the electric motor 21 of the opening / closing door drive mechanism 48 is in the initial state, and the opening / closing door 13 is held in the state shown in FIG. When the winning device 100 is in an inoperative state, the electromagnetic solenoid 35 of the movable nail drive mechanism 49 is in the initial state, that is, the plunger 36 is advanced, and the movable nail 31 is in the state shown in FIGS. It is held in a vertical state.

Therefore, the movable nail 31 is housed in the vertical groove 16 of the door 13 and closes the vertical groove 16, and the winning opening 12 of the front plate 11 is connected to the door 13 and the movable nail as shown in FIG. 31 is held in a closed state, and entry of game balls into the winning opening 12 is prohibited.
(2) First winning pattern (FIGS. 4, 6, 8, and 11)
If the output shaft 21a of the electric motor 21 of the opening / closing door drive mechanism 48 is rotated forward by the first predetermined angle θ when the winning device 100 is in the non-operating state, the second large diameter is generated along with the forward rotation of the output shaft 21a. Through the gear 20 and the first large-diameter gear 19, the small-diameter gear 18 rotates about 90 ° forward. As the small-diameter gear 18 pivots forward, the open / close door 13 pivots forward by about 90 ° and changes to a substantially horizontal state as shown in FIG.

  Further, when the prize winning device 100 is in an inoperative state, when the electromagnetic solenoid 35 of the movable nail drive mechanism 49 is energized, the plunger 36 moves backward by a predetermined stroke, and as the plunger 36 moves backward, the drive cam 34 moves. The engaging portion 34c rotates backward about the shaft portion 34b. As the engaging portion 34c rotates rearward, the pressing portion 34a also rotates rearward, and the pressure receiving portion 33a of the passive cam 33 can be rotated rearward, that is, counterclockwise in FIG. It turns about 90 ° forward due to its own weight, and changes to a substantially horizontal state as shown in FIGS.

  Therefore, when the winning device 100 is in the non-operating state, when the electric motor 21 is rotated forward by the first predetermined angle θ and the electromagnetic solenoid 35 is energized, the open / close door 13 and the movable nail 31 each move forward about 90 °. As a result, the movable nail 31 is housed in the vertical groove 16 of the door 13 and the winning opening 12 of the front plate 11 is connected to the door 13 and the movable door as shown in FIG. The nail 31 changes to the open state. Therefore, the game balls are received by the open / close door 13, and most of the game balls received by the open / close door 13 are guided to the inside of the winning opening 12.

(3) Second winning pattern (Figs. 4, 6, 9, 12)
If the output shaft 21a of the electric motor 21 of the opening / closing door drive mechanism 48 is rotated forward by a predetermined angle 2θ (strictly about 2θ) when the winning device 100 is in an inoperative state, the output shaft 21a is rotated forward. The small-diameter gear 18 rotates about 180 ° forward via the second large-diameter gear 20 and the first large-diameter gear 19. As the small-diameter gear 18 pivots forward, the open / close door 13 pivots forward by about 180 °, and falls into a vertical state (contained in the recess 14 of the front plate 11) as shown in FIG. Change.

  Further, when the prize winning device 100 is in an inoperative state, when the electromagnetic solenoid 35 of the movable nail drive mechanism 49 is energized, the plunger 36 moves backward by a predetermined stroke, and as the plunger 36 moves backward, the drive cam 34 moves. The engaging portion 34c rotates backward about the shaft portion 34b. As the engaging portion 34c rotates rearward, the pressing portion 34a also rotates rearward, and the pressure receiving portion 33a of the passive cam 33 can be rotated rearward, that is, counterclockwise in FIG. It turns about 90 ° forward due to its own weight, and changes to a substantially horizontal state as shown in FIGS.

  Therefore, when the winning device 100 is in a non-operating state, when the electric motor 21 is rotated forward by a predetermined angle 2θ and the electromagnetic solenoid 35 is energized, the open / close door 13 is turned forward by approximately 180 ° and is in a lying down vertical state. The movable nail 31 is turned about 90 ° forward and changed to a substantially horizontal state. For this reason, as shown in FIG. 12, the winning opening 12 of the front plate 11 is changed to an open state by the door 13 and the movable nail 31, but only the movable nail 31 is in a substantially horizontal state and the door 13 is not in the horizontal state. Therefore, depending on the angle at which the game ball hits the movable nail 31, the game ball is received by the movable nail 31 and guided to the inside of the winning opening 12, and the game ball is rebounded by the movable nail 31 and the winning opening 12. There is a case where it is not guided to the inside. Such a gaming state will cause the player to be relieved.

  Next, the electrical system of the pachinko gaming machine will be described based on FIG.

  In FIG. 13, the electric system has a game control board 50 as a central part, an effect control board 51, a payout control board 52 and a board external information terminal board 53 are connected to the game control board 50, and an image control board is connected to the effect control board 51. 54 and the lamp control board 55 are connected, and the frame external information terminal board 56 is connected to the payout control board 52. The game control board 50, the effect control board 51, the payout control board 52, the image control board 54, and the lamp control board 55 each include a CPU, a ROM, a RAM, an I / O, and the like.

  When the game control board 50 stops displaying the predetermined number of the start port switches 57A and 57B for detecting that the game ball has won the start winning ports 6A and 6B, and the normal symbol display unit 9, the start winning game is stopped. A start opening solenoid 58 that drives the opening 6B to open, a gate switch 59A and 59B that detects that the game ball has passed through the gates 5A and 5B, respectively, as an opportunity to operate the start opening solenoid 58, The big prize opening switch (left prize detection means 46, right prize detection means 47), the electric motor 21, the electromagnetic solenoid 35, and the game ball are the normal prize openings 4A and 4B. The normal winning opening switches 60A and 60B for detecting the winnings, the holding lamp 8 for displaying the number of balls to be held, and the game balls may pass through the gates 5A and 5B. Machine and is in normal symbol display digits are displayed varies 9, in synchronism with the presentation of the image display device 3 variably displaying special symbol special symbol display device 10 are connected, respectively. When a predetermined number fluctuates and stops on the normal symbol display 9, the start opening solenoid 58 operates to open the start winning opening 6B for a predetermined time.

  To the payout control board 52, a payout drive motor 61 that is a drive source of a prize ball payout device that pays out a prize ball, a payout ball detection switch 62 that detects a game ball paid out by the prize ball payout device, and a prize ball payout device A ball presence detection switch 63 for detecting that there is a game ball to be supplied, and a ball detection tray for storing the game ball supplied to the ball launching device is fully detected by the game ball that has been paid out. Each of the tongue detection switches 64 is connected.

  The image display device 3 and the like are connected to the image control board 54.

Next, the special winning opening process and the special winning opening switch process executed by the game control board 50 will be described in order based on FIGS.
(1) Grand prize opening process (Figs. 14-16)
14 to 16, the game control board 50 first determines whether or not it is a big hit (in a special gaming state) (step S1), and if it is a big hit, it determines whether or not it is opening. Determine (step S2). Here, “opening” means a period from the occurrence of a jackpot to the start of the first round of jackpot.

  Immediately after the occurrence of the jackpot, since the opening is in progress, it is next determined whether or not the opening time, that is, the time from the occurrence of the jackpot to the start of the first round of the jackpot has elapsed (step S3).

  Before the opening time elapses, step S1, step S2, and step S3 are repeatedly executed.

  Thereafter, when the opening time has elapsed, the round number R is incremented by “1” (step S4). Immediately after the opening time has elapsed, the number of rounds R up to that point is “0”, so the number of rounds R after addition in step S4 is “1”. Next, after clearing the winning number C to the winning opening 12 to “0” (step S5), it is determined whether or not the number of special gaming state rounds (the number of big hits) R is a predetermined number, for example, “11” or more. (Step S6). At this time, since the jackpot round number R is “1”, the determination result in step S6 is “NO”, and then the electromagnetic solenoid 35 is energized (step S7), and the electric motor 21 is moved by the first predetermined angle θ. Forward rotation (step S8).

  When the electromagnetic solenoid 35 is energized and the electric motor 21 is rotated forward by the first predetermined angle θ, the winning device 100 is in the state of the first winning pattern described above, and the game ball is received by the open / closed door 13 to be opened and closed. Most of the game balls received by the door 13 are guided to the inside of the winning opening 12.

  Next, it is determined whether or not a preset opening time, that is, a time during which the winning opening 12 can be kept open has elapsed (step S9).

  Immediately after the winning opening 12 is changed to the open state, the determination result in step S9 is “NO”, so it is next determined whether or not the winning number C to the winning opening 12 is a predetermined value “9”. However, since the determination result is “NO”, the process returns to step S1, and then step S2 is executed. The determination result in step S2 is “NO” because the opening is no longer being performed at this point, and it is then determined whether or not the winning opening 12 is open (step S11). The determination result is “YES”. Therefore, the process proceeds to step S9. Thereafter, step S9 to step S11, step S1, and step S2 are repeatedly executed.

  While repeatedly executing Step S9 to Step S11, Step S1, and Step S2, every time a game ball wins the winning opening 12, in other words, every time the big winning opening switch 47A or 47B detects a game ball, The number of winning prizes C will increase to “1”, “2”,. The counting of the number of winning prizes C will be described in the big prize opening switch process described later. When the winning number C becomes “9”, the determination result in step S10 becomes “YES”, or when the release time elapses before the winning number C becomes “9”, the determination result in step S9 becomes “YES”. It is determined whether or not the round number R has reached a predetermined number “11” or more (step S12). At this time, since the round number R is “1”, the determination result in step S12 is “NO”, the energization to the electromagnetic solenoid 35 is stopped (step S13), and the electric motor 21 is moved by the first predetermined angle θ. Reverse rotation (step S14).

  When the energization of the electromagnetic solenoid 35 is stopped, the plunger 36 is moved forward by a predetermined stroke by a built-in spring (not shown) and displaced to the original position. As the plunger 36 moves forward, the drive cam 34 is engaged. The portion 34c rotates forward about the shaft portion 34b. As the engaging portion 34c rotates forward, the pressing portion 34a also rotates forward, and the pressure receiving portion 33a of the passive cam 33 rotates forward, that is, clockwise in FIG. Then, the movable nail 31 rotates about 90 ° rearward, and changes to the retracted state as shown in FIGS.

  Further, when the electric motor 21 is reversed by the first predetermined angle θ, the small diameter gear 18 is rotated about 90 ° rearward via the second large diameter gear 20 and the first large diameter gear 19. As the small-diameter gear 18 pivots rearward, the open / close door 13 pivots rearward by about 90 ° and changes to a retracted state as shown in FIG.

  Therefore, when the energization to the electromagnetic solenoid 35 is stopped and the electric motor 21 is reversed by the first predetermined angle θ, the winning device 100 returns to the non-operating state described above.

  After executing step S14, it is determined which stop symbol at the time of jackpot occurrence is a predetermined symbol A, B, or C (steps S15, S16), and when the stop symbol is A, It is determined whether or not the jackpot round number R has reached the predetermined number “5” (step S17). If the stop symbol is B, whether or not the jackpot round number R has reached the predetermined number “10” is determined. A determination is made (step S18), and if the stop symbol is C, it is determined whether or not the jackpot round number R has reached a predetermined number “15” (step S19). At this time, since the first round is completed and the number of jackpot rounds R is “1”, the determination result is “NO” in any of steps S17, S18, and S19. Return to step S1.

  After returning to step S1, after step S1 and step S2, step S11 is executed. At this time, the winning opening 12 is not open, so the determination result in step S11 is “NO”, and then the ending It is determined whether or not there is (step S20). Here, ending is the number of rounds R (in this embodiment, “5” when the stop symbol is A, “10” when the stop symbol is B, “15” when the stop symbol is C) This is the time when the jackpot end effect is performed in the image display device 3 after the end of.

  At this point, since it is immediately after the end of the first round, the determination result in step S20 is “NO”, and it is next determined whether or not the interval time has passed (step S21). Here, the interval time refers to a preset delay time from when the winning opening 12 is closed to when the winning opening 12 is opened to start the next round. At this time, since the winning opening 12 is immediately after closing, the determination result in step S21 is “NO”, and the process returns to step S1.

  After returning to step S1, step S1, step S2, step S11, step S20 and step S21 are repeatedly executed before the interval time elapses.

  Thereafter, when the interval time elapses, the determination result in step S21 is “YES”, then the round number R is added by “1”, the round number R is set to “2” (step S4), and the winning number C is set to “ It is cleared to “0” (step S5), and it is determined whether or not the round number R has reached a predetermined number “11” or more (step S6). At this time, since the round number R is “2”, the determination result in step S6 is “NO”, the electromagnetic solenoid 35 is energized (step S7), and the electric motor 21 is rotated forward by a predetermined angle θ (step S8). ). Thereby, the winning device 100 changes to the state of the first winning pattern described above, and the second round is started.

  In the second round, the same process as the process in the first round described above is performed, and when the winning number C reaches “9” or before the winning number C reaches “9”, the opening time elapses. When this occurs, energization of the electromagnetic solenoid 35 is stopped and the movable nail 31 is displaced to the retracted state (step S13), and the electric motor 21 is reversed by the first predetermined angle θ to displace the open / close door 13 to the retracted state ( Step S14), the winning device 100 is changed to the non-operating state described above.

  After execution of step S13 and step S14, the same processing as when the first round is completed is performed, and the third round is started after the interval time has elapsed.

  Thereafter, when the stop symbol at the time of jackpot occurrence is A, the third round, the fourth round, and the fifth round are performed, and when the fifth round is completed, the determination result of step S17 is reversed to “YES”, and the round The number R is cleared to “0” (step S22), and ending is started (step S23). Thereafter, when the ending time has elapsed (step S24), the ending is terminated and the jackpot is terminated (step S25).

  If the stop symbol at the time of jackpot occurrence is B, the third round, the fourth round,... The tenth round are performed, and when the tenth round is completed, the determination result in step S18 is reversed to “YES”. The round number R is cleared to “0” (step S22), and ending is started (step S23). Thereafter, when the ending time has elapsed (step S24), the ending is terminated and the jackpot is terminated (step S25).

  If the stop symbol at the time of jackpot occurrence is C, the third round, the fourth round, ... the tenth round is performed, and when the tenth round ends and the round number R reaches the predetermined number "11" The determination result in step S6 is reversed to “YES”, the electromagnetic solenoid is energized (step S26), and the electric motor 21 is rotated forward by the second predetermined angle 2θ (step S27).

  When the electromagnetic solenoid 35 is energized and the electric motor 21 is rotated forward by the second predetermined angle 2θ, the winning device 100 is changed to the state of the second winning pattern described above, and the game ball depends on the angle at which the game ball hits the movable nail 31. There are cases where the ball is received by the movable nail 31 and guided to the inside of the winning opening 12, and when the game ball is bounced back by the movable nail 31 and is not guided to the inside of the winning opening 12, causing the player to be relieved. It will be.

(Step S32, Step S33), 15 prize ball commands are set and transmitted to the payout control board 52 (Step S34). The payout control board 52 that has received the 15 prize balls command outputs a command signal to the payout drive motor 61, and the payout drive motor 61 is driven to pay out 15 prize balls.

  As described above, the pachinko gaming machine according to the present embodiment is a pachinko gaming machine including the winning device 100 and the game control board 50. The winning device 100 includes the winning port 12 and the plurality of vertical grooves 16. The opening / closing door 13 that opens and closes the winning opening 12, the opening / closing door drive mechanism 48 that drives the opening / closing door 13, and the opening / closing door 13 are rotated in the front-rear direction using the lower end (horizontal shaft portion 17) of the winning opening 12 as a rotation axis. A movable nail 31 configured to be able to pass through the longitudinal groove 16 and rotating in the front-rear direction with the lower end (horizontal shaft 32) of the winning opening 12 as a rotation axis, and a movable nail drive mechanism 49 for driving the movable nail 31 are provided. The game control board 50 is a first winning pattern according to the number of rounds in the special game state, and the movable nail 31 is accommodated in the vertical groove 16 of the door 13 so that both the door 13 and the movable nail 31 are accommodated. An open prize opening that is kept in an almost horizontal position 2 is a first winning pattern or a second winning pattern in which a game ball can easily enter, and the movable nail 31 is detached from the inside of the vertical groove 16 of the open / close door 13 and the open / close door 13 is laid down in a substantially vertical state. The opening / closing door drive mechanism 48 and the movable nail drive mechanism 49 are controlled so as to generate a second winning pattern that keeps the movable nail 31 in a substantially horizontal state and keeps the game balls from entering the winning opening 12 in the open state. .

  According to the present embodiment, in addition to the first winning pattern similar to the conventional one, a second winning pattern is generated. In the second winning pattern, even when the open / close door 13 is open, the game is applied to the movable nail 31 in the horizontal state. Depending on the angle at which the ball hits, a case where the game ball is received by the movable nail 31 and guided into the winning opening 12 and a case where the game ball bounces back at the movable nail 31 and is not guided into the winning hole 12 are generated. Therefore, even if the open / close door 13 is open, it is unclear whether or not the game ball can enter the winning opening 12, and the player can be relieved.

  In the above-described embodiment, the winning device 100 is controlled by the first winning pattern from the first round to the tenth round when the jackpot is generated, and the second winning pattern from the eleventh round to the fifteenth round. As another example, the first to fifth rounds may be controlled by the second winning pattern, and the sixth to fifteenth rounds may be controlled by the first winning pattern, respectively.
