Description

  The present invention relates to a pachinko gaming machine.

  As is well known, as a pachinko gaming machine, a start prize opening and a big prize opening are provided in the game area on the game board surface, an open / close door that opens and closes the big prize opening, and a game ball won in the big prize opening is detected. A winning ball detection means, a winning ball payout device that pays out a predetermined number of gaming balls when a winning ball is detected by the winning ball detection means, and a winning number count that counts the number of gaming balls detected by the winning ball detection means If a random number is acquired on the main board (game control board) on the control side in response to a winning of a game ball at the start winning opening, and if the acquired random number matches a predetermined jackpot random value, There is known a pachinko gaming machine that is configured such that a predetermined number of rounds keeps the open / close door open and allows a game ball to enter a big prize opening.

Here, when a big hit occurs, each time a game ball wins a prize winning opening that is opened and opened, the winning ball is detected by the winning ball detecting means, and a predetermined number of balls are detected by the winning ball payout device. When the game ball is paid out and the game ball is counted by the winning number counting means, and the count value of the winning number counting means reaches a predetermined value, in other words, a predetermined number of gaming balls wins the prize winning opening. In this case, the door is changed from the open state to the closed state, and then the door is changed from the closed state to the open state again after a predetermined time has elapsed, and a series of operations as described above are repeated for a predetermined number of rounds. Prior to the present application, the prior art was investigated, and Patent Document 1 was found.
Japanese Patent Laid-Open No. 2002-210087

  However, the conventional pachinko gaming machine has a relatively long distance from the position of the open / closed door to the position of the winning ball detection means, which is equivalent to a game ball that changes the door from the open state to the closed state. When the game ball to be detected is detected by the winning ball detection means, it is likely that a subsequent game ball has already entered the big winning opening, and if such a situation occurs, There was a problem that a larger number of game balls than the number won in the grand prize opening.

  The present invention solves the problems of the prior art as described above, and allows a pachinko gaming machine capable of limiting the number of game balls to be awarded to an open large winning opening (winning opening) to a predetermined number. The purpose is to provide.

  Furthermore, the present invention is a problem that easily occurs in connection with limiting the number of game balls to be awarded to the open big winning opening (winning opening), that is, the game balls to the big winning opening (winning opening). This solves the problem that the number of game balls to be paid out to the player is reduced, resulting in a disadvantage to the player, even though the number of winnings has not reached the predetermined number, and the large winning opening (winning port) is closed. The purpose is to provide a pachinko machine that never happens.

  The pachinko gaming machine according to the present invention includes a winning opening through which a game ball can enter, an open / close door that opens and closes the winning opening, a winning ball detection means that detects a gaming ball won in the winning opening, and the winning ball detection A prize ball payout device for paying out a predetermined number of game balls when a game ball is detected by the means, and a winning number counting means for counting the number of game balls detected by the winning ball detection means; In a pachinko gaming machine configured to keep the number of the open / close doors open and allow the game balls to enter the winning opening, the game balls scheduled to be won are detected on the back of the open / closed doors. Detection means, and opening / closing door control means for controlling the opening / closing operation of the opening / closing door based on a count value of the winning number counting means and a signal from the winning game ball detection means, the opening / closing door control means, Prize winning When the count value of the number counting means is another predetermined value smaller than the predetermined value, when the winning game ball detecting means detects a game ball, or the count value of the winning number counting means becomes the predetermined value The door is controlled to change from an open state to a closed state, and the open / close door control means controls the open / close door based on the game ball detection of the scheduled game ball detection means in the previous round. Corresponds to the round in which the state has changed from the open state to the closed state, and the previous round corresponds to the round in which the count value of the winning number counting means is less than the predetermined value, the opening / closing in the next round Control which delays the timing which changes a door from an open state to a closed state only for a predetermined period is characterized.

  In each pachinko machine of the present invention, each time a game ball wins a winning opening in which an open / close door is opened and opened, the winning ball is detected by the winning ball detecting means, and a winning ball payout device As a result, a predetermined number of game balls are paid out and the game balls are counted by the winning number counting means.

  When the count value of the winning number counting means is other predetermined value smaller than the predetermined value, for example, when the predetermined value is N and the other predetermined value is N-1, the count value is N-1. When the game ball is placed on the back surface of the open / closed door, the game ball is detected by the winning game ball detecting means, and the open / close door control means receives the detection signal from the winning game ball detecting means. Change the open / close door from open to closed.

  Alternatively, when the count value of the winning number counting means is N-1, the winning game ball detecting means does not detect the game ball, and when the count value becomes N, the open / close door control means opens the open / close door. Transition from the open state to the closed state.

  Therefore, the game ball placed on the back surface of the open / closed door is spilled from the back surface of the open / close door and is not detected by the winning ball detecting means. A predetermined number of game balls are paid out by the apparatus, but the game ball is detected by the scheduled game ball detection means when the count value of the winning number counting means reaches another predetermined value N-1. The game ball corresponds to the game ball when the count value of the winning number counting means reaches a predetermined value N, except when another game ball has already entered the winning opening until the time. For this reason, the number of game balls to be won in the winning opening when the open / close door is in the open state matches the predetermined number N.

  However, not all game balls placed on the back surface of the open / close door may enter the winning opening, and it may be assumed that the game balls fall from the back surface of the opening / closing door and do not enter the winning opening. In such a case, the count value of the winning number counting means remains N-1, and a predetermined number of game balls corresponding to one winning number are not paid out, and the player suffers a disadvantage. .

  However, when the above-described problem occurs in the previous round, the open / close door control means is configured to perform control for delaying the timing for changing the open / close door from the open state to the closed state for a predetermined period in the next round. Therefore, the game balls that have not been paid out in the previous round can be paid out in the current round, and the disadvantage given to the player can be covered.

  Here, on the rear surface of the open / closed door in a position facing the left end of the open / close door or the left end of the open / close door and a portion facing the right end of the open / close door or the right end of the open / close door If the wall that prevents the game ball placed on the door from spilling from the left or right end of the door is provided, the rate at which the game ball spills on the back of the open door will be reduced. Can do.

  In addition, in order to prevent a game ball placed on the back surface of the open / close door from falling down from the tip of the open / close door when the open / close door is closed, an uneven portion is formed on the back surface of the open / close door. It is possible to reduce the rate at which the game ball once placed on the back surface of the door falls from the front end of the door.

  In addition, in order to prevent a game ball placed on the back surface of the open / close door from falling down from the front end of the open / close door when the open / close door is closed, a protrusion is formed at the front end of the open / close door. It is possible to reduce the rate at which the game ball once placed on the back surface of the door falls from the front end of the door.

  The image display device 3 and the like are connected to the image control board 24.

  Next, the big prize opening process and the big prize opening switch process executed by the game control board 20 will be described in order based on FIGS.

(1) Grand prize opening process (Figs. 6-9)
6 and 7, the game control board 20 first determines whether or not it is a big hit (step S1), and if it is a big hit, it determines whether or not it is opening (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, it is determined whether or not the flag F1 is turned on (step S5). At this time, since the flag F1 is turned off in advance, the determination result in step S5 is “NO”. Next, after the winning number C to the big winning opening 55 is cleared to “0” (step S6), A command signal is output to the special winning opening solenoid 30, and the open / close door 51 is changed from the closed state to the opened state, and the special winning opening 55 is changed from the closed state to the opened state (step S7).

  Next, it is determined whether or not the flag F2 is turned on (step S8). At this time, since the flag F2 is turned off in advance, the determination result in step S8 is “NO”, and then the 1R process A (FIG. 8) is executed (step S9).

  In the 1R process A (FIG. 8), it is determined whether or not a preset opening time, that is, a time during which the special winning opening 55 can be kept open has elapsed (step S9a).

  Immediately after the big prize opening 55 is changed to the open state, the determination result in step S9a is “NO”. Next, whether the number C of winning prizes to the big prize opening 55 is a predetermined value N, for example, “9”. (No in step S9b), and since the determination result is “NO”, the winning number C is next set to another predetermined value smaller than the predetermined value “9”, for example, N−1 (“8”). It is determined whether or not there is (step S9c). Since the determination result is “NO”, the process returns to step S1, and then executes step S2. 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 special winning opening 55 is open (step S10). Since “YES”, the process proceeds to step S8. Thereafter, step S8, steps S9a to S9c, step S1, step S2, and step S10 are repeatedly executed.

  While repeatedly executing Step S8, Steps S9a to S9c, Step S1, Step S2, and Step S10, every time the game ball B wins the big winning opening 55, in other words, the big winning opening switch 63A or 63B is played. Each time a ball is detected, the winning number C increases as “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 is “8”, the determination result in step S9c is “YES”, whether or not the magnetic sensor 57 of the open / close door 51 is turned on, in other words, the magnetic sensor 57 is connected to the back surface of the open / close door 51. It is determined whether or not the game ball B placed on 51a is detected (step S9d), and when the magnetic sensor 57 does not detect the game ball B, the process returns to step S1, and steps S1, S2, S10, Steps S8 and S9a to S9d are repeatedly executed.

  When step S1, step S2, step S10, step S8, and steps S9a to S9d are repeatedly executed, the game ball B is placed on the back surface 51a of the open / close door 51, and the magnetic sensor 57 detects the game ball B. Then, the determination result in step S9d is “YES”, the flag F1 is turned on (step S9e), the output of the command signal to the big prize solenoid 30 is stopped, and the open / close door 51 is changed from the open state to the closed state. The special winning opening 55 is closed (step S11). Next, it is determined whether or not the round number R is “15” (step S12). At this time, since the round number R is “1”, the determination result in step S12 is “NO”, and the process returns to step S1.

  Further, when step S1, step S2, step S10, step S8, and steps S9a to S9d are repeatedly executed, before the magnetic sensor 57 of the open / close door 51 detects the game ball B, the big prize opening switch 63A or 63B. When the game ball B is detected, in other words, when the winning number C reaches “8”, there is already a game ball B that has passed through the open / close door 51 and entered the big winning port 55. When the sphere B passes through the left sphere detection outlet 62A or the right sphere detection outlet 62B, the winning number C increases to “9”, so the determination result of step S9b becomes “YES” Step S11 is executed, the open / close door 51 is changed from the open state to the closed state, the special winning opening 55 is closed, and the process returns to Step S1 through Step S12.

  Further, when step S1, step S2, step S10, step S8, and steps S9a to S9d are repeatedly executed, the magnetic sensor 57 of the open / close door 51 and the left sphere detection discharge port portion 62A or the right sphere detection discharge port If neither of the magnetic sensors 63A or 63B of the part 62B detects the game ball B and the opening time has elapsed, the determination result of step S9a is “YES”, step S11 is executed, and the door 51 is opened. It changes to a closed state, the special winning opening 55 is closed, and it returns to step S1 through step S12.

  After the big prize opening 55 is closed as described above and the process returns to step S1, after step S1 and step S2, step S10 is executed. At this point in time, the big prize opening 55 is closed. The determination result is “NO”, and it is then determined whether or not ending is in progress (step S13). Here, “ending” means when the jackpot end effect is performed in the image display device 3 after the fifteenth round is ended.

  At this point, since it is immediately after the end of the first round, the determination result in step S13 is “NO”, and it is next determined whether or not the interval time has passed (step S14). Here, the interval time refers to a preset time from the time when the big prize opening 55 is closed to the time when the big prize opening 55 is opened to start the next round. At this point in time, since the winning prize opening 55 has just been closed, the determination result in step S14 is “NO”, and the process returns to step S1.

  After returning to step S1, before the interval time elapses, step S1, step S2, step S10, step S13 and step S14 are repeatedly executed.

  After that, when the interval time elapses, the determination result in step S14 is “YES”, then the round number R is added by “1”, the round number R is set to “2” (step S4), and the flag F1 is turned on. It is determined whether or not (step S5).

  Since the determination result in step S5 is “YES”, it is next determined whether or not the number C of winning prizes is “8” (step S15).

  Here, in the case where the winning number C is “8”, after the winning number C reaches “8” in the previous round, the game ball B is placed on the back surface 51 a of the opening / closing door 51, and the opening / closing door 51. A case where the game ball B falls from the back surface 51a of the open / close door 51 and does not enter the grand prize winning opening 55 when the state changes from the open state to the closed state.

  If the determination result in step S15 is “NO”, in other words, if the winning number C is the predetermined value “9” in the previous round (first round), the winning number C is cleared to “0”. (Step S6), the special winning opening 55 is opened, and the second round is started (Step S7). In the second round, the same process as in the first round described above is performed. When the winning sensor C is “8”, the magnetic sensor 57 of the door 51 is turned on, or the winning number C is When the winning number C reaches “9” without turning on the magnetic sensor 57 of the open / close door 51 at “8”, or when the opening time elapses before the winning number C reaches “9”. The winning opening 55 is closed (step S11).

  On the other hand, if the determination result in step S15 is “YES”, in other words, if the winning number C is “8” that does not reach the predetermined value “9” in the previous round (first round), the flag F2 Is turned on (step S16), the flag F1 is turned off (step S17), the winning number C is cleared to "0" (step S6), the special winning opening 55 is opened, and the second round is started (step) S7). In the second round, it is determined whether or not the flag F2 is turned on (step S8). Since the flag F2 is turned on at this time, the 1R process B is executed (step S18).

  In the 1R process B (FIG. 9), it is determined whether or not a preset opening time has elapsed (step S18a). Immediately after the big winning opening 55 is changed to the open state, the determination result in step S18a is “ NO ”is determined. Next, it is determined whether or not the number C of winning prizes C to the big winning opening 55 is a predetermined value“ 9 ”(step S18b). Returning to S1, step S1, step S2, step S10, step S8, step S18a, and step S18b are repeatedly executed. After that, when the winning number C reaches a predetermined value “9”, the determination result in step S18b is “YES”, and it is then determined whether or not the magnetic sensor 57 is turned on (step S18c). When the ball B is not detected, it is determined whether or not the winning number C has reached “10” (step S18d). When the magnetic sensor 57 is turned on when the winning number C is “9”, or when the winning number C reaches “10” before the magnetic sensor 57 is turned on, the determination result of step S18c or step S18d is “ YES, the flag F2 is turned off (step S18e), and the special winning opening 55 is closed (step S11). The closing of the special winning opening 55 (step S11) is also executed when the opening time has elapsed (step S18a).

  After the big prize opening 55 is closed, the same processing as when the first round is finished is performed, and the third round is started after the interval time elapses.

  Thereafter, the third round, the fourth round,... The fourteenth round are performed, and when the fifteenth round is completed, the determination result in step S12 is “YES”, and the round number R is cleared to “0” (step S19). Ending is started (step S20). Thereafter, when the ending time elapses (step S21), the ending is terminated and the jackpot is terminated (step S22).

(2) Grand prize opening switch processing (Figure 10)
In FIG. 10, the game control board 20 adds the winning number C by “1” when the big winning opening switch 63A or 63B is turned on (step S31), and the winning ball is winning (step S32, step S33). Fifteen commands are set and transmitted to the payout control board 22 (step S34). The payout control board 22 having received the 15 prize balls command outputs a command signal to the payout drive motor 32, and the payout drive motor 32 is driven to pay out 15 prize balls.

  As described above, the pachinko gaming machine according to the present embodiment includes a winning opening (large winning opening 55) through which the game ball B can enter, and an open / close door 51 that opens and closes the winning opening (large winning opening 55). A game ball B is detected by a winning ball detecting means (large winning opening switch 63A, 63B) for detecting the gaming ball B won in the winning opening (large winning opening 55) and a winning ball detecting means (large winning opening switch 63A, 63B). When detected, a game ball B detected by a prize ball payout device (payout drive motor 32) for paying out a predetermined number (15) of game balls B and a winning ball detection means (big prize opening switches 63A, 63B). With a winning number counting means (game control board 20) for counting the number of games, and the opening / closing door 51 is kept open for a predetermined number of rounds so that the game ball B can enter the winning opening (large winning opening 55). Is done. In addition, the pachinko gaming machine according to the present embodiment includes a winning game ball detecting means (magnetic sensor 57) for detecting the game ball B placed on the back surface 51a of the open / close door 51, and a winning number counting means (game). Open / close door control means (large winning opening solenoid 30 or the like) for controlling the opening / closing operation of the open / close door 51 based on a count value C of the control board 20) and a signal from the winning game ball detecting means (magnetic sensor 57). The open / close door control means (large winning opening solenoid 30 or the like) has a count value C of the winning number counting means (game control board 20) other than the predetermined value N−1 (“9”). 8 ”) when the winning game ball detecting means (magnetic sensor 57) detects the game ball B, or the count value C of the winning number counting means (game control board 20) is a predetermined value N (“ 9 )) When it reaches 51 is controlled to change from the open state to the closed state, and the open / close door control means (large winning opening solenoid 30 or the like) detects the game ball detected by the winning game ball detecting means (magnetic sensor 57) in the previous round. This corresponds to the round in which the opening / closing door 51 has changed from the open state to the closed state, and the previous round has a count value C of the winning number counting means (game control board 20) of less than a predetermined value N (“9”). In the case of the round that ended in step S3, control is performed to delay the timing for changing the opening / closing door 51 from the open state to the closed state for a predetermined period in the next round. Here, in the above embodiment, if the previous round corresponds to a round ended when the count value C of the winning number counting means (game control board 20) is less than the predetermined value N (“9”), step S18b, As shown in step S18c and step S18d, in the next round, the winning number is incremented by “1” and a predetermined number (15) of gaming balls B are controlled to be paid out. This corresponds to “control for delaying the timing for changing the opening / closing door 51 from the open state to the closed state by a predetermined period”. In addition, you may make it perform control which extends time itself instead of the said embodiment.

  In each round, the pachinko gaming machine according to the present embodiment has a winning ball detecting means (large winning a prize) every time the gaming ball B wins a winning opening (large winning opening 55) in which the open / close door 51 is opened and opened. The winning ball B is detected by the mouth switch 63A, 63B), and a predetermined number (15) of the gaming balls B are paid out by the winning ball payout device (payout drive motor 32) and the winning number counting means (game control board 20). ), The game ball B is counted.

  When the count value C of the winning number counting means (game control board 20) is another predetermined value N−1 (“8”) smaller than the predetermined value N (“9”), the game ball B is opened. When placed on the back surface 51a of the open / close door 51 in the state, the game ball B is detected by the winning game ball detecting means (magnetic sensor 57), and the open / close door control means (large winning port solenoid 30 or the like) When the detection signal is received from the ball detection means (magnetic sensor 57), the door 51 is changed from the open state to the closed state.

  Alternatively, when the count value C of the winning number counting means (game control board 20) is N−1 (“8”), the winning game ball detecting means (magnetic sensor 57) does not detect the game ball B, When the count value C becomes N (“9”), the opening / closing door control means (large winning opening solenoid 30 or the like) changes the opening / closing door 51 from the open state to the closed state.

  Therefore, the game ball B placed on the back surface 51a of the open / close door 51 is in a state where it falls from the back surface 51a of the open / close door 51 and does not enter the winning opening (large winning port 55). Detected by the winning ball detecting means (large winning port switches 63A, 63B), a predetermined number (15) of game balls B are paid out by the winning ball payout device (payout drive motor 32). The time when the game ball B is detected by the winning game ball detecting means (magnetic sensor 57) from the time when the count value C of the means (game control board 20) reaches another predetermined value N-1 ("8"). The game ball B has a predetermined count value C of the winning number counting means (game control board 20) unless the other game balls B have already entered the winning opening (large winning opening 55). Game when it reaches the value N (“9”) Corresponding to B. For this reason, the number of game balls B that wins the winning opening (large winning opening 55) when the open / close door 51 is in the open state matches the predetermined number N (“9”).

  However, the game balls B placed on the back surface 51a of the open / close door 51 in the open state do not all enter the winning opening (large winning port 55), and fall down from the back surface 51a of the opening / closing door 51 to win the prize. It is also assumed that the player does not enter the mouth (large winning opening 55). In such a case, the count value C of the winning number counting means (game control board 20) remains N−1 (“8”), and a predetermined number (15) of game balls B corresponding to one winning number. Will not be paid out, and the player will be penalized.

  However, when the above-described problem occurs in the previous round, the opening / closing door control means (large winning opening solenoid 30 or the like) has a predetermined timing for changing the opening / closing door 51 from the open state to the closed state in the next round. Since it is configured to perform control that delays only for a period, it is possible to pay out the game ball B that was not paid out in the previous round in this round, and it is possible to cover the disadvantage given to the player become.

  Here, the back surface 51a of the open / closed door 51 is placed on the left end of the open / close door 51 or the left end of the open / close door 51 and on the right end of the open / close door 51 or the right end of the open / close door. Since the wall portions 59A and 59B are provided to prevent the game ball B placed thereon from falling down from the left end portion or the right end portion of the open / close door 51, the game ball placed on the back surface 51a of the open / close door 51 is open. The fall rate can be reduced.

  Further, in order to prevent the game ball B placed on the back surface 51a of the open / close door 51 from falling down from the front end of the open / close door 51 when the open / close door 51 is closed, an uneven portion 58a is formed on the back surface 51a of the open / close door 51. Therefore, the rate at which the game ball B once placed on the back surface 51 a of the opening / closing door 51 falls from the tip of the opening / closing door 51 can be reduced.

  Further, in order to prevent the game ball B placed on the back surface 51a of the open / close door 51 from falling off from the front end of the open / close door 51 when the open / close door 51 is closed, the protruding portion 51b is formed at the front end of the open / close door 51. The rate at which the game ball B once placed on the back surface 51 a of the open / close door 51 falls from the front end of the open / close door 51 can be reduced.
