JP 2002-360822 A

  In a pachinko gaming machine having a conventional configuration having a plurality of large winning openings as described above, one of the large winning openings is controlled to open and close during execution of the special game operation, and a game ball is placed in the opened large winning opening. Prize balls are generated by the inflow. Here, as the special game operation, there is known a configuration in which a plurality of big prize winning openings are controlled so as to be sequentially opened and closed in a predetermined order. In such a configuration having a plurality of special winning openings, a game ball can flow only into the special winning opening opened during the execution of the special game operation, and a gaming ball is inserted into the closed special winning opening. Inflow is impossible. As a result, the number of game balls flowing into the big prize opening during the execution of the special game operation is limited, and the prize balls are paid out according to all the game balls flowing into the big prize opening.

  However, in contrast to the above-described conventional configuration, there is an illegal act of illegally trying to acquire a large number of prize balls by increasing the number of game balls flowing into the big prize opening by illegally opening the closed big prize opening. It has occurred. As this fraudulent act, during the execution of the special game operation, the closed prize winning opening is illegally opened by a thin plate inserted from the gap of the machine base, and the gaming ball is originally inserted into the prize winning opening where the gaming ball does not flow. It is going to win many prize balls by making inflow possible.

  On the other hand, in order to prevent such an illegal act, a sensor or the like for detecting the occurrence of the illegal act is provided, and a warning sound or a warning light is activated by detecting the illegal act by the sensor. Are known. However, since a sensor that detects fraud may malfunction, it is common for a game to continue even if the sensor detects a fraud and generates a warning sound or the like. In particular, during the execution of a special game operation, if the progress of the game is interrupted by detecting an illegal act of the sensor, the player may suffer a great disadvantage if the detection is a malfunction. Therefore, even if an illegal act is detected, the game continues to proceed. Therefore, when an illegal act is performed during the execution of the special game operation, an illegal prize ball (profit) is generated by continuing the game.

  The present invention proposes a pachinko gaming machine that can prevent an illegal act of illegally opening a closed big prize opening.

  The present invention provides a large winning opening device provided with a large winning opening that can be opened and closed on a game board, an open / close door that opens and closes the large winning opening, and a driving means that opens and closes the open / close door. The ball detecting means for detecting the game ball that has flowed into the winning opening and the predetermined special gaming conditions are established, so that the large winning opening apparatus is driven and controlled, and the opening and closing operations of the open / close door are repeated a predetermined number of times. In a pachinko gaming machine comprising special game control means for executing a special game operation and prize ball payout means for paying out a prize ball when the ball detection means detects a game ball that has flowed into a special winning opening. The prize ball payout means enables the detection of the game ball by the ball detection means of the big prize opening according to the opening operation of the opening / closing door by the driving means of the big prize opening device, and the ball detection means according to the closing operation of the door by the driving means Game ball detection by That as a result a pachinko game machine according to claim.

  In such a configuration, the detection of the game ball by the ball detection means of the special prize opening is made valid or invalid in conjunction with the opening and closing operations of the open / close door by the driving means of the special prize opening device. Therefore, the winning ball is paid out when the gaming ball flows into the big winning opening opened by the driving means. And even if a game ball flows into the big winning opening not opened by the driving means, the prize ball is not paid out. That is, it is possible to prevent an unfair profit (prize ball) from being generated due to unauthorized opening of the special winning opening not opened by the driving means. Therefore, even if the game continues while the unauthorized opening is being performed, the profits due to the unauthorized acts are not provided. Therefore, according to the configuration of the present invention, it is possible to substantially prevent an illegal act of illegally opening the special winning opening to obtain many prize balls.

  Furthermore, as described above, the configuration of the present invention interlocks the opening / closing operation of the open / close door by the driving means of the grand prize opening device and the control for enabling or disabling the detection of the game ball by the ball detecting means. Therefore, the opening / closing operation of the opening / closing door according to various operation modes can be dealt with reliably and stably.

  In the pachinko gaming machine of the present invention described above, when the prize ball paying means passes a predetermined delay time from the closing operation timing of the door by the driving means of the big prize opening device, the big prize of the big prize opening device is concerned. A configuration is proposed in which the game ball detection by the mouth ball detection means is disabled.

  Here, it is common that the ball detecting means is provided in the back of the special winning opening. Thereby, there is a time lag between the timing when the game ball flows into the winning prize opening and the timing when the ball detection means detects the game ball. Therefore, by determining the delay time based on this time lag, the game ball that has flowed in immediately before closing the big prize opening can be detected as valid by the ball detection means. In this way, by delaying the timing for invalidating the detection of the game ball by the ball detection means by a delay time from the closing operation timing of the opening / closing door, a prize ball based on the game ball flowing into the opened big winning opening is appropriately generated. can do.

  In the pachinko gaming machine of the present invention described above, a plurality of big prize opening devices are arranged, a plurality of ball detecting means are arranged for each big winning prize port, and the special game control means is established by the establishment of the special game condition, A configuration is proposed in which any one of the special prize opening devices is selected, and the special prize opening device is driven and controlled to execute a special game operation.

  Here, the special game control means may select one big prize opening device and execute a special game operation, or select a plurality (including all) big prize opening devices and play a special game at the same time. The operation may be executed. In the latter case, the special game operation may be executed simultaneously with a plurality of selected big prize opening devices, or may be executed sequentially. Then, the special game control means performs a process of selecting one or a plurality of special prize opening devices that execute the special game operation. Further, when the detection of the game ball is enabled according to the opening operation of the open / close door by the driving means of the special prize opening device, the prize ball payout means is in the period until the next invalidation according to the closing operation of the open / close door. Maintain state. Similarly, when invalidated according to the closing operation of the door, the invalid state is maintained until it is validated according to the opening operation of the door.

  In such a configuration, the detection of the game ball by the ball detecting means arranged for each big winning opening, in conjunction with the opening and closing operation of the open / close door by the driving means of each big winning opening device, Since it is set to be valid or invalid, a prize ball is not paid out even if a game ball flows into a big prize opening which is not opened by the driving means among a plurality of big prize opening devices. That is, it is possible to prevent an unfair profit (prize ball) from being generated due to unauthorized opening of the special winning opening. Therefore, according to the configuration of the present invention, it is possible to substantially prevent an illegal act of illegally opening the special winning opening and obtaining many prize balls during execution of the special game operation.

  Furthermore, even in the configuration provided with the opening detection sensor for the special winning opening as described above, the configuration of the present invention can be applied, so that the detection by the opening detection sensor is invalidated during the execution of the special game operation. However, the effect of the present invention that a prize ball is not generated by an illegal act is exhibited.

  In the pachinko gaming machine of the present invention described above, the prize ball payout means executes a process of paying out a prize ball according to the ball detection signal by inputting the ball detection signal from the ball detection means of the big prize opening. And each of the ball detecting means of each big winning opening comprises a signal input conversion means for converting the ball detection signal to be input and a signal non-input state to be disabled for input, The winning ball payout means converts the signal input conversion means into a signal input state in accordance with the opening / closing door opening operation by the driving means of the large prize opening device, and converts it into a signal non-input state in accordance with the opening / closing door closing operation by the driving means. The structure which controls is proposed.

  In such a configuration, the ball detection signal is not input from the ball detection means of the big prize opening not opened by the driving means. Then, the ball detection signal is input and the winning ball is paid out only by the detection of the game ball by the ball detection unit of the big prize opening opened by the driving unit. Therefore, even if a game ball flows into the grand prize opening due to an illegal act of illegally opening the big prize opening, there is no input of a ball detection signal, so that the generation of prize balls due to the inflow of game balls is surely prevented. it can. Therefore, the above-described operational effects of the present invention can be exhibited more stably and reliably.

  Here, in this configuration, the signal non-input state in which the ball detection signal from the ball detection unit cannot be input is invalidation of the detection of the game ball by the ball detection unit. Further, the signal input state is to enable the detection of the game ball by the ball detection means.

  As the signal input conversion means, for example, the signal non-input state is configured such that the ball detection means does not transmit the ball detection signal, or the ball detection signal transmitted from the ball detection means reaches the prize ball payout means. The structure etc. which do not do can be used suitably. In the former case, a configuration having a function capable of switching control processing between the transmission (signal input state) and non-transmission (signal non-input state) of the sphere detection signal, or the supply state (signal A configuration including a function that can be changed between an input state) and a non-supply state (signal non-input state) is applicable. On the other hand, in the latter case, the signal transmission line through which the ball detection signal travels from the ball detection means to the prize ball payout means can be opened (signal input state) and unblockable (signal non-input state). It is possible to apply a configuration including a function that can be changed. As such a signal input conversion means, a device that performs a conversion operation between an input (signal input state) and a non-input (signal non-input state) of a ball detection signal is preferably used, and a mechanical conversion operation is performed. Is preferred.

  As described above, the pachinko gaming machine according to the present invention enables the detection of the game ball by the ball detecting means of the big prize opening in accordance with the opening operation of the opening and closing door by the driving means of the big prize opening device, and the opening and closing door by the driving means. Since the detection of the game ball by the ball detecting means is invalidated according to the closing operation of the game, even if an illegal act of illegally opening the big prize opening is performed, the illegal release is performed. No prize balls are generated based on game balls that flow into the big prize opening. Therefore, it is possible to substantially prevent an illegal act of illegally opening the special winning opening.

Next, the main part of the present invention will be described.
The pachinko gaming machine 1 described above has a configuration including two big winning holes 26a, 26b, and when the big hit random number value is hit and judged and the special symbols A, B, and C are confirmed and stopped, A special game operation for selectively opening or closing any of the special winning openings 26a, 26b is executed. Hereinafter, Examples 1 and 2 will be described sequentially.

  In the configuration of the first embodiment, according to the special symbols A, B, and C, the special game operation in which one of the big winning holes 26a and 26b is selected and the open / close round is repeated is executed in accordance with the winning stop pattern mode. I have control. Specifically, the big hit symbol random number value is validated by hitting the big hit random number value as described above, and the big hit symbol random number value is stopped in the odd stop symbol type (1, 3, 5, 7, 9). When it is determined to do so, an open / close round is executed in which the left prize opening device 25a is enabled and the big prize opening 26a is opened and closed. On the other hand, if it is determined that the big-hit symbol random number value stops in the hit-hit symbol mode of even-numbered symbols (0, 2, 4, 6, 8), the right big winning hole device 25b is activated and the big winning hole 26b is activated. Perform an open / close round to open / close. When the jackpot symbol random number is determined to be an odd symbol, the closed state is maintained without executing the open / close round at the right winning prize opening 26b. When the jackpot symbol random number value is determined to be an even symbol, the closed state is maintained without executing the open / close round at the left prize winning opening 26a.

  In the above-described special symbol processing, as shown in FIG. 4, when the jackpot random number value is hit, the jackpot symbol random number value is validated, and when the jackpot symbol random number value is an odd symbol, the odd game flag = 1 is set. On the other hand, if the jackpot symbol random number is an even symbol, the even game flag = 1. Then, when the special symbols A, B, and C are confirmed and stopped in the winning stop symbol mode, the special game flag = 1 is set. When the special game flag = 1, by the big prize opening process of FIG. 5, when the odd number game flag = 1, the left big prize opening device 25a is enabled and the big prize opening solenoid 28a is driven and controlled, and the big prize is won. An open / close round is performed to open and close the mouth 26a. That is, by driving the big prize opening solenoid 28a, the opening / closing door 27a is opened to open the big prize opening 26a, and the predetermined opening limit time (30 seconds) expires or a predetermined number (9) of prizes accompany it. Then, the open / close door 27a is closed to close the special winning opening 26a. In this way, the opening / closing round in which the opening / closing door 27a is opened and then closed is repeatedly executed a predetermined number of times (15 times). On the other hand, when the even-numbered game flag = 1, the right prize opening device 25b on the right side is activated and the big prize opening solenoid 28b is driven and controlled to open and close the opening / closing round after opening / closing the door 27b a predetermined number of times. Execute repeatedly. As described above, in the first embodiment, the special game operation in which the opening / closing round is repeated at only one of the two large winning openings 26a and 26b is executed. This special game operation is executed according to the same operation mode regardless of which of the special winning openings 26a, 26b.

  Here, the big prize opening solenoids 28a and 28b of the first embodiment are driven by energization or non-energization of current, and hold the open / close doors 27a and 27b in a standing position in a non-energized state where no current is flowing. The open / close doors 27a and 27b are held in a tilted position tilted forward in an energized state in which a current is passed. Therefore, in the above-described special winning a prize opening process (see FIG. 5), when the special game flag = 1 and the odd game flag = 1, the special prize opening solenoid 28a is energized to maintain the energized state, and the predetermined opening limit time The energization of the special winning opening solenoid 28b is stopped by the expiration of a predetermined number of times or a predetermined number of winnings, thereby turning it off. Similarly, when the even-numbered game flag = 1, the special winning opening solenoid 28b is energized, and thereafter energization is stopped and de-energized. In this way, the opening / closing operation of the opening / closing doors 27a, 27b is controlled.

  Further, in the special winning opening process, when the special winning opening solenoid 28a is energized, the odd number release flag = 1. Thereafter, when the energization is stopped and the non-energized state is entered, the time delay of a preset delay time is started, and the odd release flag = 0 is set as the delay time elapses as shown in FIG. Yes. Similarly, if the special winning opening solenoid 28b is energized, the even release flag = 1, and the even release flag = 0 with the passage of a predetermined delay time after the energization is stopped and the energization is stopped. And Here, the delay time is set to the time required for the game balls to be detected by the respective count switches S3 and S4 after flowing into the special winning openings 26a and 26b. As a result, the game balls that flowed in immediately before the special winning openings 26a, 26b are closed can be targeted for the generation of the winning balls, and the game balls that flowed in the opened state of the special winning openings 26a, 26b are accompanied. A prize ball is generated, and the legitimate interests of the player can be preserved. Since the delay time depends on the distance from the special winning openings 26a and 26b to the count switches S3 and S4, the flow path form, and the like, the delay time is determined according to each base.

  In the prize ball payout process of FIG. 6, when the ball detection signal is generated by the count switches S3 and S4 detecting the game ball, a payout apparatus process for driving and controlling the payout apparatus 73 according to the signal input is executed. Pay out a predetermined number of prize balls. In the prize ball payout processing of the first embodiment, processing is performed so that the ball detection signal input from the count switches S3 and S4 is validated or invalidated according to the odd release flag and even release flag described above. For example, when the odd release flag = 1, the ball detection signal of the count switch S3 is validated and the ball detection signal of the count switch S4 is invalidated. Thus, when the odd release flag = 1, the payout device 73 is operated by the payout device processing according to the ball detection signal input from the count switch S3, and a predetermined number of prize balls are generated. When the odd release flag = 1, even if a ball detection signal is input from the count switch S4, no prize ball is generated. On the other hand, when the even release flag = 1, the ball detection signal of the count switch S4 is validated and the ball detection signal of the count switch S3 is invalidated. Thus, when the even release flag = 1, the payout device 73 is operated by the payout device processing in accordance with the ball detection signal input from the count switch S4, and a predetermined number of prize balls are generated. When the even release flag = 1, even if a ball detection signal is input from the count switch S3, no prize ball is generated.

  Here, as described above, the odd opening flag and the even opening flag are converted according to the operation control of the large winning opening solenoids 28a, 28b by the large winning opening process, so that the large winning opening solenoid 28a, The valid / invalid processing of the ball detection signals of the count switches S3 and S4 is performed according to the operation control of 28b. That is, when the special winning opening solenoid 28a is energized by the special winning opening process, the odd-numbered release flag = 1 (see FIG. 5), so that the winning ball is accompanied by the ball detection signal of the count switch S3 by the winning ball payout process. After that, when the delay time elapses with the special winning opening solenoid 28a in the non-energized state, the odd release flag = 0, so that no winning ball is generated even if the ball detection signal of the count switch S3 is input. (See FIG. 6). On the other hand, when the big prize opening solenoid 28b is energized by the big prize opening process, since the even-numbered release flag = 1 (see FIG. 5), the prize ball is accompanied by the ball detection signal of the count switch S4 by the prize ball payout process. After that, when the delay time elapses with the special winning opening solenoid 28b in the non-energized state, the even release flag = 0, so that no winning ball is generated even if the ball detection signal of the count switch S4 is input. (See FIG. 6). In this way, in the configuration of the first embodiment, the count switch S3 is obtained by converting the large winning opening solenoids 28a, 28b to the energized or de-energized state and opening or closing the large winning openings 26a, 26b. , S4 converts the validity / invalidity of the ball detection signal. Accordingly, a prize ball is generated along with the game ball that flows in when the special winning opening 26a, 26b is opened, and no prize ball is generated even if the game ball flows in the closed state.

  It should be noted that the special prize opening solenoids 28a and 28b are energized and the special prize openings 26a and 26b are opened only when the special game operation is being executed (special game flag = 1). Therefore, in a state where the special game operation is not executed (special game flag = 0), since the odd release flag = 0 and the even release flag = 0, even if a ball detection signal is generated by the count switches S3 and S4, The payout device 73 is not driven.

  According to the configuration of the first embodiment, when the special winning opening solenoids 28a and 28b are in a non-energized state, the special winning openings 26a and 26b are closed. Even if it is detected, the award ball is not paid out. Therefore, when a special game operation is not being executed, no prize ball is generated even if a game ball flows into both of the large winning openings 26a and 26b. Furthermore, during the execution of the special game operation, no prize ball is generated even if a game ball flows into the special winning opening 26a or 26b in which the open / close round is not executed. As a result, when an illegal act of illegally opening the closed large winning opening 26a, 26b by inserting a thin plate or the like through a gap in the machine base is performed, the gaming ball is inserted into the illegally opened large winning opening 26a, 26b. No prize balls will be paid out even if. In this way, the profit generated by the illegal act is not generated with respect to the illegal act of illegally opening the special winning openings 26a and 26b to obtain a prize ball. In other words, an illegal act of gaining profits by illegally opening the special prize openings 26a and 26b in a state where the special game operation is not executed, and a special prize opening 26a where the opening / closing round is not executed during the execution of the special game action. In addition, it is possible to reliably and stably prevent the generation of illegal profits against the illegal action of gaining profits by opening 26b illegally, and also preventing the illegal actions.

  In the first embodiment, the ball detecting means according to the present invention is configured by the count switches S3 and S4. The main control board 80 and the effect control board 82 constitute special game control means according to the present invention. The main control board 80 and the payout control board 81 constitute a prize ball payout control means according to the present invention. Further, the special game condition according to the present invention is established by setting the big hit random number value to hit and setting the special game flag = 1.

  The count switches S3 and S4 of the first embodiment detect a game ball when the generated magnetic field is changed by the passage of the game ball in an energized state as in the second embodiment described later. In the first embodiment, the count switches S3 and S4 are always energized.

  In the configuration of the second embodiment, the count switch S3 or S4 of the special winning opening 26a or 26b that is not executing the open / close round during execution of the special game operation is configured not to detect the game ball. Therefore, the ball detection signal is not input to the main control board 80 from the count switch S3 or S4 of the closed large winning opening 26a or 26b.

  Here, as the count switches S3 and S4 of the second embodiment, a magnetic field is generated by energizing from the main control board 80 through the board relay terminal plate 90, and due to the change of the magnetic field caused by the passage of the game ball, What detects a game ball is applied.

  In the second embodiment, each of the count switches S3 and S4 is provided with a switch energizing device (not shown) that converts the energized state into a non-energized state, and the switch energizing device is controlled by the main control board 80. The operation is controlled. That is, the main control board 80 controls the switch energization device to enable the detection of the game ball as an energized state and disable the detection of the game ball as a non-energized state. The switch energization device is a control device that converts between an energized state and a non-energized state, and since conventionally known devices can be applied, details thereof are omitted.

  In the second embodiment, the winning switch 26a, 26b is obtained by converting the count switches S3, S4 into the energized state or the non-energized state according to the odd number release flag and the even number function flag by the winning ball payout process of FIG. The game ball detection by the count switches S3 and S4 is validated / invalidated according to the opening / closing operation. When the odd opening flag is set to 1 in accordance with the opening operation of the big winning opening 26a, the count switch S3 is energized, and then the odd opening flag is set to 0 by the closing operation of the big winning opening 26a. On the other hand, when the even-numbered opening flag = 1 is set according to the opening operation of the special winning opening 26b, the count switch S4 is energized, and thereafter, the even-numbered opening flag = 0 is set according to the closing operation of the special winning opening 26b.

  For example, when the special game flag is set to 1 by the special symbol process (see FIG. 4) and the odd number release flag is set to 1 by the special winning opening process (see FIG. 5), the switch energizing device is executed by the prize ball payout process of FIG. And the count switch S3 provided in the special winning opening 26a is energized. Thus, when a game ball that has flowed into the special winning opening 26a is detected, the prize ball is paid out by the payout device process in accordance with the ball detection signal. Since the even release flag = 0 in this state, the non-energized state of the count switch S4 provided inside the special winning opening 26b is maintained. Thereafter, when the odd open flag = 0 and the delay time elapses, the switch energization device is controlled to put the count switch S3 in a non-energized state. As a result, the count switch S3 cannot detect the game ball and no ball detection signal is generated. During the execution of such a special game operation, even if the closed big prize opening 26b is illegally opened and a game ball flows in, the count switch S4 does not detect the game ball and no ball detection signal is generated. The prize ball is not paid out. Therefore, even if the closed large winning opening 26b is illegally opened during the execution of the special game operation, no illegal profit (prize ball) is generated, and the disadvantage that the gaming hall suffers due to the illegal profit can be prevented. . And the fraudulent act of obtaining profits by such unauthorized opening can be prevented.

  The case where the odd-numbered release flag = 1 is illustrated, but when the even-numbered release flag = 1, the count switch S4 is set in the energized state and the count switch S3 is set in the non-energized state. Further, when the special game operation is not executed, the odd number release flag = 0 and the even number release flag = 0, so that the count switches S3 and S4 are in a non-energized state. Therefore, a prize ball is not generated by the unauthorized opening of the special winning openings 26a and 26b, and such an illegal act can be prevented. As described above, even in the second embodiment, the same effects as those of the first embodiment described above can be obtained.

  In the configuration of the second embodiment, processing for converting the count switches S3 and S4 to the energized state or the non-energized state is executed according to the special game flag, the odd-numbered open flag, and the even-numbered open flag. Since the configuration other than is the same as that of the first embodiment described above, the same components are denoted by the same reference numerals and description thereof is omitted.

  In the configuration of the second embodiment, the above-described switch energization device that converts the count switches S3 and S4 between the energized state and the non-energized state constitutes the signal input conversion means according to the present invention. The state is the signal input state of the present invention, and the non-energized state is the signal non-input state of the present invention.

  In the configurations of the first and second embodiments described above, as one of the special game operations, one of the two big winning openings 26a and 26b is selected and an opening / closing round is executed. As a configuration, one or both of the big winning openings 26a and 26b may be selected to execute the open / close round. Here, when both are selected, for example, both of them may be opened / closed simultaneously, or may be alternately opened / closed in a predetermined order. Furthermore, the expiration condition for one open / close round may be set differently for the special winning opening 26a and the special winning opening 26b. For example, at the special winning opening 26a, as described above, the expiration of 30 seconds of the opening limit time or nine game ball winnings is set as the expiration condition, and at the special winning opening 26b, the expiration of the opening limitation time of 10 seconds or two. It is possible to set such that the game ball winning of is set as the expiration condition. Also, the number of executions of the open / close round may be set to a different number. Regardless of the configuration, the odd opening flag = 1 and the even opening flag = 1 are set according to the opening operation of each of the special winning openings 26a and 26b, and the odd opening flag = 0 and the even opening flag = 0 are set according to the closing operation. To do.

  Further, in the configurations of the first and second embodiments described above, the selection of the big winning openings 26a, 26b for executing the open / close round is determined according to the jackpot symbol random number value, but not limited to this, various selection conditions can be set. It is. For example, a newly selected random number value may be extracted.

  On the other hand, the configuration of the above-described second embodiment includes a switch energization device that converts the count switches S3 and S4 provided inside the special winning openings 26a and 26b to an energized state or a non-energized state. In this configuration, the count switches S3 and S4 are deactivated. However, as another configuration, a conversion device (signal input conversion means) that passes or blocks the input of the ball detection signal from the count switches S3 and S4. ). Even with the configuration for controlling the operation of the conversion device, since the ball detection signal is not input, the same effects as those of the second embodiment can be obtained.
