Description

  The present invention relates to a pachinko gaming machine, and more specifically, when a power failure such as a power interruption occurs while a player is playing a game, a power supply of a game ball that has not been paid when the power failure has occurred It relates to pachinko machines that are used at the time of recovery.

  Conventionally, a pachinko gaming machine has a plurality of winning holes on a game board surface, and the number of payout balls is predetermined for each winning hole. When the player operates the launch lever, the game ball is fired on the game board surface, and when the game ball falls into the winning opening, game balls corresponding to the number of payout balls set in the winning opening are paid out. In addition, the number of unpaid game balls that should be paid out but have not been paid out is memorized so that the payout can be made accurately even when winnings continue for a short period of time, and the number of unpaid game balls is 0. When the number is larger than that, the game balls are paid out, and when the number of unpaid game balls becomes 0, the payout of game balls is stopped. When the power is turned on, the stored value of the number of unpaid game balls is reset to zero.

  Therefore, in the conventional pachinko gaming machine, when a power supply abnormality such as a temporary drop in the power supply voltage supplied from the outside or a power interruption occurs, the above-mentioned memory of the number of unpaid game balls is not retained and the next power supply Since the stored value of the number of unpaid game balls is reset to 0 when the game is inserted, there is a problem that the payout is not executed for the number of unpaid game balls when such a power failure occurs.

  In view of the above problems, the present invention, for example, when a power supply abnormality such as a temporary drop in power supply voltage or a power supply interruption occurs, the prize ball that has not been paid when such a power supply abnormality occurs is accurately The issue is to provide a pachinko machine that pays out.

In order to solve the above problems, a pachinko gaming machine according to claim 1 of the present invention includes at least one winning opening, winning detection means for detecting whether the gaming machine is dropped or passed into the winning opening, and winning detection means. Based on the detection of a prize ball, a ball payout means for paying out a prize ball, a ball payout detection means for detecting a payout of a prize ball from the ball payout means, an unpaid amount calculated from the detection results of the winning detection means and the ball payout means First and second unpaid prize ball numbers based on the first and second unpaid prize ball number storage units for storing the number of prize balls, the detection result of the winning detection means, and the detection result of the ball payout detection means An unpaid prize ball number update processing unit for sequentially updating the number of unpaid prize balls stored in the storage unit, and the ball payout when the number of unpaid prize balls stored in the first unpaid prize ball storage unit is greater than zero. Ball payout control to let the means pay out prize balls A power supply unpaid prize ball number storage backup unit that holds the value of the first unpaid prize ball number storage unit when the voltage of the external power supply drops below a predetermined value, and the first When the number of unpaid prize balls stored in the unpaid prize ball number storage unit 2 is 0, an excessive payout error is detected when an excessive payout error is detected when a predetermined number of prize balls or more are detected. A monitoring processing unit and an initial setting unit that initializes the number of unpaid prize balls stored in the second unpaid prize ball number storage unit to 0 when power supply from an external power source is started, and a power source from the external power source A backup payout start determination processing unit that determines whether or not payout based on the number of unpaid prize balls stored in the first unpaid prize ball number storage unit at the start of supply is started, and a first unpaid prize ball number storage unit Remember A backup payout end detection processing unit for detecting the end of payout based on the number of unpaid prize balls and a payout based on the number of unpaid prize balls stored in the first unpaid prize ball number storage unit. The period from when it is detected that the backup payout end detection unit detects the end of payout based on the number of unpaid prize balls stored in the first unpaid prize ball number storage unit An error monitoring stop control unit for stopping monitoring of excessive payout errors of the error monitoring processing unit, and the backup payout start determination processing unit takes a time required from the start of power supply from an external power supply to the start of payout by backup And a value shorter than the time required from the start of power supply until the payout for the winning after the power supply starts is first. A first predetermined time storage unit for storing as a predetermined time, and when the payout is detected within the first predetermined time from the start of the power supply, it is determined that the payout by the backup is started, and the backup payout ends The detection processing unit includes a second predetermined time storage unit that stores a value slightly larger than a ball payout interval for each game ball by backup as a second predetermined time, and after the payout by the backup is started The gist of the invention is that the end of the backup payout is detected when the ball payout interval for each game ball exceeds a second predetermined time .

  Here, with the number of unpaid prize balls, the number of prize balls already paid out calculated from the detection result of the ball payout means is subtracted from the number of prize balls calculated from the detection result of the winning detection means. Numbers. The payout based on the number of unpaid prize balls stored in the first unpaid prize ball number storage section (hereinafter referred to as backup payout) refers to the first unpaid prize ball number storage section when power supply is interrupted. Is a payout that starts when the number of unpaid prize balls stored in the table is one or more. With this configuration, when an abnormality occurs in the external power supply, the unpaid prize ball number storage value at that time is held until the external voltage next becomes a predetermined value or more, and the unpaid prize ball held after the power supply is restored A sequential update process is executed on the number stored value based on the detection result of the subsequent winning detection means and the detection result of the ball payout detection means, and the prize balls are paid out so that the number of unpaid prize balls is zero. Therefore, even if a power supply abnormality occurs during the game, the number of prize balls corresponding to the number of winnings before and after the power supply abnormality is accurately paid out.

  A second unpaid prize ball number storage unit for storing the number of unpaid prize balls, and a second unpaid prize ball number storage unit based on the detection result of the winning detection means and the detection result of the ball payout detection means. A second unpaid prize ball number update processing unit that sequentially updates the number of unpaid prize balls stored and a condition in which the number of unpaid prize balls stored in the second unpaid prize ball number storage unit is zero. By providing a payout excessive error monitoring processing unit that detects that an excessive payout error has occurred when a payout of a predetermined number of prize balls or more is detected, it becomes possible to detect an excessive payout error. In addition, when the power is turned on, the stored value of the second unpaid prize ball number storage unit serving as a reference for detecting an excessive payout error is initialized to 0, and an excessive payout error is detected based on the initialized unpaid prize ball value. Therefore, there is no need to provide a means for holding the value of the second unpaid prize ball number storage unit during power interruption.

  Furthermore, a backup payout start determination processing unit that determines whether or not backup payout is executed when power supply is started, a backup payout end detection processing unit that detects the end of payout by backup, and the backup payout start determination processing unit Error monitoring stop control to stop the excessive payout error monitoring of the payout excessive error monitoring processing unit during a period from when it is determined that the payout by backup is executed until the backup payout end detection unit detects the end of payout by backup Part.

  When the power supply is resumed, the stored value of the first unpaid prize ball storage unit is 0 or more, the stored value of the second unpaid prize ball storage unit is 0, and after the power supply is resumed, the winning detection means and the payout detection Since each stored value is sequentially updated based on the detection result of the means, the stored value of the first unpaid prize ball storage unit is equal to or greater than the stored value of the second unpaid prize ball storage unit. That is, when the power supply is resumed after being interrupted, the first unpaid prize ball number storage value is retained at the time of interruption, and if the first unpaid prize ball number storage value is 1 or more, the prize ball is paid out. Is executed after the power supply is resumed, the second unpaid prize ball memory value is not retained at the time of interruption, but is initialized to 0 at the time of resume, and the first unpaid prize ball number memory value and the second unpaid prize ball number Although the stored value does not match, in this way, the excessive payout error monitoring process is stopped by stopping the excessive payout error monitoring during the period when payout is performed by the backup that may cause an erroneous detection of the excessive payout error. The problem is that the department will not detect an excessive payout error by mistake, and will erroneously detect the occurrence of an excessive payout error by judging that what is actually a valid payout is an excessive payout. Absent

  When the payout by the backup is completed, the stored value of the first unpaid prize ball number storage unit is 0, and the stored value of the second unpaid prize ball storage unit at that time is a value less than that, that is, 0. As a result, the stored value of the first unpaid prize ball storage unit matches the stored value of the second unpaid prize ball storage unit. Therefore, an excessive payout error is correctly detected after the backup payout is completed.

Further, the backup payout start determination processing unit is a value longer than the time required from the start of power supply from the external power supply to the start of payout by backup, and regarding the winning after the start of power supply from the start of power supply A first predetermined time storage unit that stores a value shorter than the time required until the payout starts as a first predetermined time, and when a payout is detected within the first predetermined time from the start of power supply, backup The backup payout end detection processing unit stores a value that is slightly larger than the ball payout interval for each game ball by backup as a second predetermined time. A time memory unit, and after the start of payout by backup, when the ball payout interval for each game ball exceeds a second predetermined time, Up dispensing end may be to be detected.

  According to the pachinko gaming machine configured as described above, the time from the start of power supply from the external power supply to the start of the first payout is compared with the first predetermined time, and whether or not the payout by the backup is started is determined. Since the payout interval does not exceed the second predetermined time until the payout by the backup starts and ends, the payout interval is compared with the second predetermined time, and the payout by the backup is performed. Can be detected. Therefore, the backup payout start determination processing unit can determine the start of backup only by monitoring the detection result of the payout detection means, and the backup payout end detection processing unit only monitors the detection result of the payout detection means. The end of backup can be determined.

  According to the pachinko gaming machine according to claim 1 of the present invention, the number of unpaid prize balls serving as a reference for the prize ball payout is the same even when a power supply abnormality occurs such that the power supply from the external power supply is reduced or shut off. Since the power is stored until the power is normally supplied from the time of the power failure, the number of prize balls that are accurately corresponding to the number of winnings before and after the occurrence of the power failure are executed. There is an effect.

  In addition, since the value of the number of unpaid prize balls serving as a basis for detection of an excessive payout error in the excessive payout error monitoring processing unit is initialized when the power is turned on, there is no need to hold the value of the number of unpaid prize balls during the power supply interruption. Such initialization has the effect of ensuring reliable payout excess error monitoring processing. On the other hand, if an excessive payout error is monitored immediately after the start of power supply, the number of unpaid prize balls calculated by the ball payout control unit does not match the number of unpaid prize balls calculated by the excessive payout error monitoring processing unit. There is a possibility of erroneously detecting an excessive payout error that has not occurred.

  However, since the error monitoring stop control means stops detecting the excessive payout error immediately after the power is turned on again, the excessive payout error is not erroneously detected. In addition, when the payout by the backup is completed, detection of an excessive payout error is started. At the start of the excessive payout error monitoring, the number of unpaid prize balls calculated by the ball payout control unit and the unpaid prizes calculated by the payout excessive error monitoring processing unit Since both the number of balls becomes zero and the number of unpaid prize balls of both coincide with each other, there is an effect that an excessive payout error can be accurately detected.

Furthermore, according to the first aspect of the present invention, it is possible to determine the start and end of backup simply by monitoring the detection result of the payout detection means. This payout detection means may be shared by those used for ball payout control and payout excessive error monitoring. That is, there is an effect that it is possible to detect the start and end of payout by backup with a simple configuration without providing new detection means.

In this gaming machine, when the left and right gate switches 113 and 114 detect that a game ball launched by the player toward the surface of the game board 14 has passed through either of the gates 61 and 62 (S10 “YES”). Based on the signal, the normal symbol display device 60 starts symbol variation (S12). The normal symbol display device 60 stops the symbol variation when 6.0 seconds have elapsed from the start of symbol variation, and determines the variation symbol (S24). If a so-called “winning” symbol (for example, 1, 3, 5, 7, or 9) appears as the final symbol (S26 “YES”), the variable start winning port 51b on the game board 14 is opened. (S28).

  Then, when a game ball wins the opened variable start winning opening 51b or the always open starting winning opening 51a (S30 “YES”), five detection signals from the start winning opening switch 110 are used. A prize ball is paid out (S31), and each variation symbol area of the special symbol display device 50 starts symbol variation in the order of the left symbol 50a, the middle symbol 50b, and the right symbol 50c (S32). The symbols 50a, 50b, 50c are stopped (S40).

  When the combination of the confirmed symbols displayed in each of the variable symbol areas 50a, 50b, 50c of the special symbol display device 50 is a “big hit” symbol (“YES” in S42), the big prize opening 52 is continuously repeated a predetermined number of times. It is opened (16 times) (S43). On the other hand, when the combination of the “big hit” symbol is a so-called specific symbol, the special symbol display device 50 is operated until the special symbol display device is operated next after the stop of the series of hitting operations this time and the confirmed symbol becomes the big hit symbol. The lottery probability relating to the jackpot is set so as to shift to a high probability, and the process ends (S44 “YES”, S48). When the combination of the “big hit” symbol is a so-called normal symbol (non-specific symbol), the special symbol display device is activated after the current stoppage of the series of hitting operations until the final symbol becomes a big bonus symbol. The lottery probability related to the jackpot of the display device 50 is set so as to shift to a low probability, and the process ends (S44 “NO”, S50).

  Incidentally, the combination of the “big hit” symbol is a combination symbol in which the left symbol 50a, the middle symbol 50c, and the right symbol 50b indicate the same number. For example, the combination of the “left symbol, middle symbol, right symbol” is “1, 1, The symbols “1”, “2, 2, 2”, “3, 3, 3” are applicable. Also, among the jackpot symbols, “3, 3, 3”, “5, 5, 5”, “7, 7, 7”, “Gold, Gold, Gold”, “Sakura, Sakura, Sakura”, “Jade, The “ball, ball” is a specific symbol, and the other jackpot symbols are normal symbols.

  On the other hand, when the game ball launched toward the game board 10 side wins the prize holes 54 to 57 provided on the game board 14 side or the big prize opening 52 when opened (S16 “YES”). ), 5, 7, or 15 winning balls are paid out per winning ball based on the detection signals from the winning detection switches 111, 112, 119a, b, c, d (S18). If no winning opening is awarded, it is processed as “out” (S20). Further, if the “big hit” symbol is not obtained due to the confirmation of the variation symbol of the special symbol display device 2 (“NO” in S42), it is processed as “out of” (S46).

When the screw 137a is rotationally driven by driving the prize ball payout motor 136a, the game balls from the game ball tank 77 and the tank rail 78 described above move through the game ball payout bar 122 in the downstream direction as a whole. In addition to being introduced into the prize ball payout device 80a, the game balls in the prize ball payout device 80a are moved downstream by the screw 137a and fall from the open lower end in order from the downstream one, and the prize ball holding portion 125 is placed. To be paid out. The ball payout device 80b for prize balls has the same configuration and function.

  FIG. 9 shows a control block diagram of main parts of the pachinko gaming machine according to the present embodiment. The main control unit 900 is provided on the main control board 91 and includes a ROM 901, a central processing unit (CPU) 902, and a RAM 903. Power is supplied from the AC24V power plug 109 via the power switch 95. However, an activation delay circuit 904 is provided and activates later than the ball payout control unit 800. Here, it is assumed that the delay is 0.4 s. In addition, the main control unit 900 includes, as input systems, the start winning opening sensors 110a and 110b, the large winning opening sensor 111, the specific area sensor 112, the left gate sensor 113, and the right gate sensor 114. The left sleeve winning port sensor 119a, the right sleeve winning port sensor 119b, the left falling winning port sensor 119c, the right falling winning port sensor 119d, the emptying prevention switch 82, and the full tank switch 83 are connected. As the output system, the large winning opening variable wing solenoid 115, the large winning opening door solenoid 116, the specific area door solenoid 117, the winning ball error LED 150, the broken ball LED 151, the special symbol display device 50, and the normal symbol display device. 60 is connected.

  The ball payout control unit 800 is provided on the ball payout board 88, and includes a RAM 803, a central processing unit (CPU) 804, and a ROM 805, and performs processing based on programs and data stored in the ROM 805. In addition, the ball payout control unit 800 is provided with a voltage drop detection circuit 801 that detects that the power supply voltage supplied to the ball payout control unit 800 has dropped and outputs a voltage drop detection signal. Are input to the external NMI signal terminal of the CPU 804 and the backup power source 802.

  Since the AC 24V power supplied to the ball payout control unit 800 is supplied to the ball payout control unit 800 via the main control unit 91, the voltage of the power supply supplied to the power plug 109 is accidentally damaged. When the power supply voltage to the main control 900 is lowered or cut off, the power supply voltage to the payout control unit 800 is also lowered or cut off. However, the backup power supply 802 receives the voltage drop detection signal. Since the power is supplied to the RAM 803, the CPU 804, and the ROM 805, the ball payout control unit 800 performs a predetermined process for the occurrence of a backup when an abnormality occurs in the power from the power plug 109. It is possible to execute.

  The payout control unit 800 is connected with the ball lending button 32, the error release switch 94, the prize ball sensors 138a and 138b, and the lending ball sensors 138c and 138d as an input system, and the prize system as the output system. The ball payout motor 136a, the lending ball payout motor 136b, the frequency and error indicator 35, and the firing motor control unit 104 are connected. Then, on the signal line to the firing motor control unit 104, a firing stop signal for switching the potential on or off is transmitted. The firing motor control unit 104 controls the firing motor 101 to stop when the firing stop signal is on, and to move the firing motor when it is off. Further, a prepaid card unit 30 is connected to the ball payout control unit 800, and an operation signal of the ball lending button 32 is transferred to the prepaid card unit 30 and communicated with each other.

  Between the main control unit 900 and the ball payout control unit 800, a signal line for transmitting a strobe signal (STB signal) from the main control unit 900 and a prize ball command for instructing the number of payout balls from the main control unit 900. The error occurrence command for notifying the occurrence and type of the error and the error release command for notifying the error and the type of the error are connected by a signal line for 8-bit parallel transmission. The STB signal is input to the external NMI signal terminal of the CPU 804.

  Next, processing executed by the main control unit 900 will be described. 10 to 17 are flowcharts for explaining the operation of the main control unit 900. FIG. 10 shows a main routine. This main routine is executed once every about 4 ms (milliseconds), for example. First, in A01, it is determined whether the initialization determination data at a predetermined address in the RAM is a predetermined value. When an abnormality occurs in the execution of the program or when the power is turned on, the value becomes indefinite. Therefore, the determination result is “NO”, and the work area is initialized and a predetermined value is set by A10. On the other hand, in other cases, the determination in A01 is “YES” and the process proceeds to A02.

  In A02, a random number such as a jackpot determination random number used in the main control unit 900 and an updating of the operating counter and timer, that is, an addition process are executed. Subsequently, in A03, the start winning opening sensors 110a and 110b, the respective winning opening sensors 111, 112, 119a, b, c, d, the left and right gate sensors 113, 114, the winning ball sensors 138a and 138b, and prevention of emptying. Based on the outputs of the switch 82 and the full tank switch 83, the state of each sensor and each switch is detected.

  Subsequently, in A04, based on the winning to the start winning opening 51 detected in A03, the symbol variation of the special symbol display device 50 is started, whether or not the jackpot determination random number is extracted and the jackpot operation is executed. The process of determining and outputting a command signal to the special symbol display device 50 and the special winning opening driving solenoid 116 is executed. Subsequently, in A05, based on the passage of the right and left gates detected in A03, the symbol variation of the normal symbol display device is started, and a hit determination random number is extracted to determine whether or not to execute the hit operation. The command signal is output to the normal symbol display device 60 and the start winning opening variable wing solenoid 115.

  Subsequently, in A06, the number of unpaid prize balls that should be paid out but not paid out is calculated based on the number of wins at each prize opening and the number of prize balls to be paid out, and the payout by backup is performed. Whether or not the prize balls are paid out without excess or deficiency, whether or not the supply of game balls to the ball payout devices 136a and 136b is normally performed, and the game balls on the payout path A process for determining whether or not the ball is full is performed, and further, a process for outputting a command for instructing the number of payouts to the ball payout control unit 800 based on a winning at each winning opening is performed. The program ends.

  FIG. 11 is a flowchart showing a subroutine program of the prize ball payout control process shown in A06. It is determined whether or not a prize ball has been paid out by B01, and if a prize ball payout is detected, the number of unpaid prize balls is subtracted by 1 in B02 (however, when 0, it is not subtracted), and then to B03. If the award ball is not paid out, the process proceeds to B03. In B03, the number of payout balls related to the winning when the winning is detected in A03 is sequentially added to the number of unpaid winning balls for each time, and the payout balls of each time are awarded for up to 10 recent winnings. The numerical data is stored together with the winning order. The number of unpaid prize balls is calculated by the subtraction process of B02 and the addition process of B03, and is stored and managed up to a predetermined number (for example, 65535 that can be managed in a 2-byte area).

  Successively, in B04, a backup payout monitoring process for determining whether or not a payout has been made is performed in B04. In B05, a prize ball is paid out when there is no unpaid prize ball number. In B06, a process for monitoring an excessive payout error is a process for monitoring an award ball non-detection error in which a payout is not performed even though the number of unpaid prize balls remains. In B08, a process for monitoring an empty switch preventing switch error in which a game ball supplied with a shortage is monitored is performed in B08 to monitor a full tank error that is filled with a game ball downstream of the ball payout device in the pachinko gaming machine.

  Subsequently, in B09, when the payout ball number data is stored in B03, the payout ball number data stored in the payout information storage process shown in B03 corresponds to the first payout data. The payout command to be sent is transmitted and the payout ball number data is deleted. That is, only one prize ball command is transmitted at a time. In addition, when a full tank error, empty spin prevention switch error, prize ball payout non-detection error or prize ball payout excessive error occurs, or when a full tank error, empty spin prevention switch error and prize ball payout non-detection error are canceled, each error A command corresponding to the occurrence or each error cancellation is output to the ball payout controller 800, and this program ends.

  By the way, the commands transmitted in B09 are each composed of 2 bytes of data, and the command transmitted in one B09 processing is maximized because the above four types of errors occur at the same time, together with the error generating commands. This is a case where a prize ball command is transmitted. In this case, five commands (10 bytes) are transmitted. Each command is divided into 1 byte, and each byte is output to the ball payout controller 800 in parallel for 200 μs (microseconds). At the same time, a strobe signal (pulse signal having a pulse width of 50 μs within each 200 μs) STB) is output to the ball payout controller 800. Therefore, it takes about 2 ms at maximum for one transmission.

  Note that the priority of command transmission is that an error occurrence command and an error cancel command (hereinafter referred to as an error command) have priority over a prize ball command, and within the error, a prize ball payout excessive error, a prize ball payout ball non-detection error, The priority is given to the switch error prevention switch and the mantan switch error. The command is transmitted even during an error or during payout by backup.

  FIG. 12 is a flowchart showing a subroutine program for the payout payout monitoring process shown in B04. In C01, it is determined whether or not the first sphere monitoring end flag indicating that the first sphere monitoring process has already ended is set. If it is set, the process proceeds to C21, and if it is not set, the process proceeds to C02. . When the power is turned on, the first sphere monitoring end flag is set not to be set by the initial setting, and the process proceeds to C02.

  In C02, it is determined whether or not the first ball monitoring flag is set. If it is set, the process proceeds to C05. If it is not set, the timer T1 is started by C03, and C04 is set. After the first ball monitoring flag (cleared when the power is turned on) is set, the process proceeds to C05. In C05, when an error occurs, the timer T1 is stopped, and a timer stop process for setting a timer stop flag is executed.

  Subsequently, in C06, it is determined whether or not the timer suspension flag is set. If it is set, the process ends. If not, the process proceeds to C07. In C07, it is determined whether or not a prize ball payout is detected. If it is detected, a first ball monitoring end flag (cleared when the power is turned on) is set in C12. On the other hand, if not detected, the value of the timer is determined by C08. If the value is 1.5 s (seconds) or more, the first ball monitoring end flag is set in C09 and C10 is set. The second and subsequent balls monitoring end flag is set, and the prize ball payout excessive error monitoring execution flag is set at C11 to end. If the value of the timer is not 1.5 seconds or more in C08, the process ends as it is.

  In C21, it is determined whether or not the second and subsequent sphere monitoring end flag indicating that the second and subsequent sphere monitoring processing has already been completed is set. When the second and subsequent sphere monitoring processing has been set, this subroutine is terminated. Proceed to C22. When the power is turned on, the second and subsequent balls monitoring end flag is not set by the initial setting. Therefore, unless the second and subsequent balls monitoring end flag is set in C09, the process proceeds to C22.

  In C22, it is determined whether or not the second and subsequent sphere monitoring flag is set. If it is set, the process proceeds to C25. If it is not set, the timer T2 is started by C23, and the second is started by C24. After the ball and subsequent monitoring flag (cleared when the power is turned on) is set, the process proceeds to C25. In C25, when an error occurs, the timer T2 is stopped and a timer stop process for setting a timer stop flag is executed.

  Subsequently, in C26, it is determined whether or not the timer suspension flag is set. If it is set, the process ends. If not, the process proceeds to C27. In C27, it is determined whether or not a prize ball payout is detected. If it is detected, the timer T2 is reset in C31 and restarted. On the other hand, if not detected, it is determined in C28 whether or not the timer value is 0.3 s or more, and if it is 0.3 s or more, the second and subsequent monitoring end flag is set in C29. , C30 sets the award ball payout excessive error monitoring execution flag, and the process ends. When the value of the timer T2 is not 0.3 seconds or more, the process ends.

  Therefore, according to this subroutine, when 1.5 seconds elapses without detecting the payout of the prize ball after the power is turned on, the payout of the unpaid prize balls stored by the backup in the ball payout control unit (hereinafter referred to as “ball prize payout by backup”). ).), The first ball payout monitoring process end flag and the second ball and later monitor process end are set, and the prize ball payout excessive error monitoring execution flag is set. The prize ball payout excessive error is monitored without performing the monitoring process for the first ball and the second ball and subsequent balls relating to the payout.

  On the other hand, if the payout ball is detected within 1.5S after the power is turned on, it is determined that there is a backup winning ball and the winning ball payout by the backup has started, and only the first ball monitoring process end flag is set. . After that, the second and subsequent balls are monitored, and if an event that does not detect the payout ball continues for 0.3 s or more after the start of the backup winning ball, it is determined that the backup winning ball has ended. Since the second ball monitoring process end flag and the winning ball payout excessive error monitoring execution flag are set, the paying ball payout excessive is not performed after that, without performing the monitoring process for the first ball and the second ball or later related to payout by backup. Monitor errors.

  By the way, 1.5s for monitoring the start of a prize ball by backup considers the time difference between the start of the main board and the start of the prize ball board, the detection time of error occurrence and error release, the prize ball payout motor operation time, etc. ing. In addition, 0.3s for monitoring the end of the winning ball due to the backup takes into consideration the operating time of the winning ball payout motor and the like.

  FIG. 13 is a flowchart showing a subroutine program for timer stop processing at the time of error shown in C05 and C25. In D01, at least one of the error flags of the award ball payout excessive error, the award ball payout non-detection error, the emptying prevention switch error and the full tank error (hereinafter referred to as the main control unit monitoring payout error) monitored by the main control unit. If any error flag is set, the process proceeds to D02. If any error flag is not set, the process proceeds to D05.

  In D02, a timer (timer T1 is shown when this subroutine is called at C05, and timer T2 is shown when this subroutine is called at C25. Hereinafter, the same applies to the description of this subroutine). It is determined whether or not a timer aborting flag, which is a flag indicating whether or not it has been aborted, is set. When the timer aborting flag is not set, the timer is stopped by D03 and the timer is being aborted by D04. Set the flag.

  In D05, it is determined whether or not the timer aborting flag is set. When the timer aborting flag is set, the timer is reset by D06, the timer is started by D07, and the timer aborting flag by P08. To clear. When the timer suspension flag is not set, the processing is terminated as it is.

  Therefore, according to this subroutine, when the state where none of the error flags of the main controller monitoring payout error is set continues, the timer operation is not stopped and the timer stopping flag is not set. When the error flag related to any of the main control unit monitoring payout errors is set, the timer operation is stopped and the timer stopping flag is set, and any error flag of the main control unit monitoring payout error is set. When changing from the set state to the unset state, the timer is reset and restarted, and the timer abort flag is cleared.

  FIG. 14 is a flowchart showing a subroutine program of the prize ball payout excessive error monitoring process shown in B05. In E01, it is determined whether or not the prize ball payout excessive error monitoring execution flag is set. If it is set, the process proceeds to E02, and if it is not set, the process is terminated. In E02, it is determined whether or not the number of unpaid prize balls is 0. If it is 0, the process proceeds to E03, and if it is not 0, the prize ball excessive payout error monitoring flag is cleared by E11, and the process ends. To do.

  At E03, it is determined whether or not the winning ball payout excessive error monitoring flag is set. If it is set, the process proceeds to E04. If it is not set, the excess counter is reset by E12, and the winning ball is returned by E13. Set the payout excess error monitoring flag and end. In E04, it is determined whether or not a prize ball has been detected. If yes, 1 is added to the prize ball payout excess counter value in E05, and the process proceeds to E06. If not, the process ends.

  In E06, it is determined whether or not the value of the winning ball payout excess counter exceeds 10, and if so, the transmission command “A003H” is stored in the transmission command storage area of the RAM 903 in E07, and E08 is stored. The prize ball error LED is turned on, a prize ball payout excessive error flag indicating that a prize ball payout excessive error has occurred is set in E09, the prize ball payout excessive monitoring flag is cleared in E10, and the process ends.

  Therefore, by this subroutine processing, when the winning ball paying-out excessive error monitoring execution flag is set, the winning ball paying-out excessive number to be paid out when the unpaid winning ball number value is 0 is counted. If it exceeds, it is determined that an excessive payout error has occurred. That is, when the number of unpaid prize balls counted and stored by the main control unit is zero until the prize ball payout excessive error monitoring execution flag is set by the payout monitoring process by the backup, 10 or more prizes are awarded. Even if a ball is paid out, it is not determined that an award ball payout excessive error has occurred.

  FIG. 15 is a flowchart showing a subroutine program of the prize ball payout non-detection error monitoring process shown in B06. In F01, it is determined whether or not the full tank error flag or the idling prevention switch error flag is set. In F02, it is determined whether or not the number of unpaid winning balls is zero. If the determination result of either F01 or F02 is “YES”, the process proceeds to F20, the prize ball payout non-detection error monitoring flag is cleared, and the process ends. On the other hand, if the determination result of either F01 or F02 is “NO”, the process proceeds to F03.

  In F03, it is determined whether or not the prize ball payout non-detection error flag is set. If it is set, the process proceeds to F21, and if it is not set, the process proceeds to F04. In F21, it is determined whether or not a prize ball payout is detected. If a prize ball payout is detected, the transmission command “C002H” is stored in the transmission command storage area in F22, and the prize ball error LED is indicated in F23. Is turned off and the prize ball payout non-detection error flag is cleared in F24 and the process ends. If no prize ball payout is detected, the process ends.

  In F04, it is detected whether or not the winning ball payout undetected error monitoring flag is set. If it is set, the process proceeds to F08. If not set, the winning ball payout undetected error is detected in F05. The monitoring timer is reset, the winning ball payout undetected error monitoring timer is started in F06, the winning ball payout undetected error monitoring flag is set in F07, and the process proceeds to F08.

  In F08, it is determined whether or not prize ball payout is detected. If detected, the prize ball payout non-detection error monitoring timer is reset in F14 and the process ends. If not detected, F09 is executed. Proceed to In F09, it is determined whether or not the value of the prize ball payout undetected error monitoring timer is 3.5 s or more. If it is 3.5 s or more, the transmission command “A002H” is stored in the command storage area in F10. Then, the prize ball error LED is turned on in F11, the prize ball payout non-detection error flag is set in F12, the prize ball non-detection error monitoring flag is cleared in F13, and the process ends.

  Therefore, if the number of unpaid prize balls is 1 or more and the prize ball is not dispensed for 3.5 seconds or more by this subroutine, it is determined that a prize ball withdrawal non-detection error has occurred, The ball error LED is turned on, a prize ball payout non-detection error flag is set, and when a prize ball payout is detected thereafter, it is determined that the prize ball payout non-detection error has been canceled, and the prize ball error LED is turned off. The winning ball payout non-detection error flag is cleared. However, when a full tank error or an empty cut prevention switch error has occurred, it is not determined whether a prize ball payout undetected error has occurred.

  FIG. 16 is a flowchart showing a subroutine program of the idle cut prevention switch error monitoring process shown in B07. In G01, it is determined whether or not the idling prevention switch error flag is set. If it is set, the process proceeds to G13, and if it is not set, the process proceeds to G02. In G02, it is determined whether or not an off switch is detected. If off is detected, the process proceeds to G03. If no off switch is detected, an empty switch error is detected in G12. Reset the monitoring timer and exit.

  In G03, it is determined whether or not the idle cut prevention switch error monitoring flag is set. If it is set, the process proceeds to G07, and if not set, the idle cut prevention switch error monitoring timer is set in G04. In G05, the timer is started. In G06, the idling prevention switch error monitoring flag is set, and the process proceeds to G07. In G07, it is determined whether or not the value of the idling prevention switch error monitoring timer is equal to or greater than 0.1 s. If it is not equal to or greater than 0.1 second, the process ends. If it is equal to or greater than 0.1 second, the process proceeds to G08. The transmission command “A001H” is stored in the transmission command storage area, the ball-out LED is turned on at G09, the idling monitoring flag is cleared at G10, and the idling prevention switch error flag is set at G11. To finish.

  In G13, it is determined whether or not the idling prevention switch is detected to be on. If on is detected, the process proceeds to G14. If no sensing is detected, the idling prevention switch error is detected in G23. Reset the release monitoring timer and exit. In G14, it is determined whether or not the idle error release monitoring flag is set. If it is set, the process proceeds to G18. If not set, the idle timer switch error release monitoring timer is set in G15. Is reset, G16 starts the timer, G17 sets the idle error cancellation monitoring flag, and proceeds to G18.

  In G18, it is determined whether or not the value of the idling prevention switch error release monitoring timer is 1.0 s or more. If it is not 1.0 s or more, the process ends. If it is 1.0 s or more, the process ends in G19. The transmission command “C001H” is stored in the transmission command storage area, the ball break LED is turned off at G20, the idling prevention switch error release monitoring flag is cleared at G21, and the idling prevention switch error flag at G22. To finish.

  Therefore, if the idle prevention switch is turned off for 0.1 s or longer by the subroutine processing, it is determined that an idle prevention switch error has occurred, the ball break LED is turned on, the ball break prevention switch error flag is set, After that, when the idling prevention switch is turned on for 1 s or longer, it is determined that the idling prevention switch error has been canceled, the ball running out LED is turned off, and the idling prevention switch error flag is cleared.

  FIG. 17 is a flow chart showing a subroutine program for the full tank error monitoring process shown in B08. In H01, it is determined whether or not the full tank error flag is set. If it is set, the process proceeds to H13, and if it is not set, the process proceeds to H02. In H02, it is determined whether or not the full tank switch is detected. If the switch is detected, the process proceeds to H03. If the switch is not detected, the full tank error monitoring timer is set in H12. Reset and exit.

  In H03, it is determined whether or not the full tank error monitoring flag is set. If it is set, the process proceeds to H07. If it is not set, the full tank error monitoring timer is reset in H04. The timer is started. In H06, a full tank error monitoring flag is set, and the flow proceeds to H07. In H07, it is determined whether or not the value of the full tank error monitoring timer is 0.2 s or more. If it is not 0.1 seconds or more, the process ends. If it is 0.2 seconds or more, the transmission command is sent in H08. “A000H” is stored in the transmission command storage area, the full error monitoring flag is cleared in H09, the full error flag is set in H10, and the process ends.

  In H13, it is determined whether or not the full switch is detected to be off. If off is not detected, the process is terminated. If off is detected, the transmission command “C000H” is transmitted in H14. The data is stored in the transmission command storage area, and the full error flag is cleared in H15 and the process is terminated. Therefore, according to this subroutine program, when the full tank switch is continuously turned on for 0.2 s or more, it is determined that a full tank error has occurred, the full tank error flag is turned on, and then the full tank switch is turned off. It is determined that the full tank error has been cancelled, and the full tank error flag is cleared.

  Next, processing executed by the ball payout control unit 800 will be described. 18 to 25 are flowcharts for explaining the operation of the ball payout control unit 800. In the ball payout control unit 800, the main program is always executed, and during the execution, four types of interrupts are generated. The priority order of the interrupts is NMI interrupt, CH0 interrupt, CH1 interrupt, and CH2 interrupt. Yes. The maximum number of interrupts is CH1 interrupt, CH0 interrupt, and 10 NMI interrupts during CH2 interrupt. Therefore, the processing of the CH2 interrupt, CH1 interrupt, CH0 interrupt, and NMI interrupt 10 times is set to less than 2.5 ms which is the minimum interrupt time of the CH2 interrupt.

  FIG. 18 shows the main program. When the power is turned on, it is determined in J01 whether or not the backup flag is set. If not set, the RAM initialization process including the process of setting the initial operation flag in J02 is performed, and then the process proceeds to J05. If it is set, the initial operation flag is set by J03, the prize ball payout excessive number counter is reset by J04, and then the process proceeds to J05.

  In J05, it is determined whether or not the error release switch is pressed. If not, the process proceeds to J07. If it is pressed, the communication error stored in the RAM 805 of the ball payout control unit 800 is stored in J06. After canceling the prize ball payout excessive error, prize ball piece payout error, prize ball payout undetected error, lending ball piece payout error, and lending ball payout undetected error, the process proceeds to J07.

  In J07, the initial operation flag is processed to clear the initial operation flag when a predetermined time elapses after the power is turned on. Subsequently, in J08, according to the values of the predetermined error flag and the initial operation flag. A firing motor control process for controlling the state of the firing stop signal is executed. Subsequently, in J09, a process of outputting a prize ball signal to the outside is performed every 10 winning ball payouts, and in J10, a process of outputting the lending ball information to the outside is performed for every 25 lending ball payouts.

  Subsequently, in J11, a display symbol to be displayed on the error indicator 93 is selected. Specifically, when the initial operation flag is displayed, “−” is selected as the display symbol, and when all the error flags and the initial operation flag are not set, “0” is selected as the display symbol. If at least one error flag is set, the corresponding error number is selected. Table 1 shows the correspondence between error flags and display symbols. When a plurality of errors occur at the same time, priority is given to the display symbols corresponding to the errors shown at the top in Table 1. For example, if a communication error and a prize ball payout undetected error occur simultaneously, “1” corresponding to the communication error is selected.

  Subsequently, in J12, when the connection confirmation signal from the card unit is monitored and it is detected that the signal is turned off, it is determined that a card unit non-connection error has occurred, and a card unit non-connection error flag is set. turn on. In J13, the start (acceleration) of the prize ball payout motor is monitored. When the initial operation error flag is set and as shown in Table 2 below, a communication error, a prize ball payout excessive error, a prize ball payout excessive error, a prize ball piece payout error, a prize ball payout undetected error, an empty When one or more of a cut prevention switch error or a full tank error has occurred, the winning ball payout motor is stopped. However, when an idle prevention switch error or a full tank error has occurred, the payout is stopped after the payout during the operation is completed. Table 2 shows whether or not the prize ball payout motor, the lending ball payout motor, and the firing motor are stopped when each error occurs.

  In J14, the operation (acceleration) start of the rental ball payout motor is monitored. Then, when the initial operation error flag is set and as shown in Table 2, the emptying prevention switch error, the full tank error, the card unit not connected error, the communication time error, the lending ball one-off error, the lending ball non-detection error When one or more of these occur, the rental ball payout motor is stopped. However, when an idle prevention switch error or a full tank error has occurred, the payout is stopped after the payout during the operation is completed.

Subsequently, in J15, card unit processing including signal processing at the time of lending ball payout operation and input signal confirmation processing from the card unit is executed. However, this processing is not executed during lending by a backup. The signal processing during the lending ball payout operation and the operation of the input signal confirmation process from the card unit will be described.
(A) Signal processing during lending ball payout operation The ball payout control unit 800 turns on the stand READY signal (PRDY) when the payout operation is possible. After receiving ON of the card unit READY signal (BRDY) from the card unit in the state where PRDY is ON, when detecting that the terminal terminal lending request completion confirmation signal (BRQ) output from the card unit is ON, The terminal terminal lending completion signal (EXS) is turned ON in order to prepare for receiving the payout request and notify that the preparation has been made. Then, when there is a change in BRQ to OFF, that is, a payout request signal, the payout control unit 800 executes a payout operation, and then turns off EXS to notify that the payout has been completed. Subsequently, when the BRQ ON is received, the next payout is started, and when the BRDY OFF is received, the ball lending is terminated.

(A) Input signal confirmation processing from the card unit After the PRDY is turned ON, normal input from the card unit is received even if the BRQ lending request monitoring time, lending instruction monitoring time, next request confirmation timing and lending completion monitoring time are exceeded. If not, the stand READY signal (PRDY) is switched at a predetermined timing in the order of ON, OFF, ON, OFF, ON, OFF, ON. At this time, if the stand terminal lending completion signal (EXS) is ON, the stand READY signal (PRDY) is turned OFF during the first OFF.

  When a lending ball payout request is received by the terminal terminal lending request completion confirmation signal (BRQ), the number corresponding to the lending ball payout request is added to the value of the unpaid lending ball number count. After executing J15, the process returns to J07, and thereafter the processes of J07 to J15 are repeated.

  FIG. 19 is a flowchart showing a subroutine program of the initial operation control process shown in J07. In K01, it is determined whether or not the initial operation flag set in J03 is set when the power is turned on. If set, the process proceeds to K02, and if not set, the process ends. In K02, it is determined whether the initial operation monitoring timer is operating. If it is not operating, the timer is started and then the process proceeds to K04. If it is operating, the process proceeds to K04. At K04, when the value of the initial operation monitoring timer exceeds 1.6 s, the initial operation flag is cleared at K05 and the process ends. When it does not exceed 1.6 s, the process ends. By this subroutine, the initial operation flag is set for 1.6 seconds after the power is turned on.

  FIG. 20 is a flowchart showing a subroutine program of the firing motor control process shown in J08. In L01, it is determined whether or not the initial operation flag is set. When the initial operation flag is set, in L04, the firing motor 101 is turned on by turning on the firing stop signal output from the ball payout control unit 800 to the firing motor 104. To stop and exit. On the other hand, when it is not set, the process proceeds to L02. At L02, as shown in Table 2 above, an error flag of any one of a communication error, a prize ball payout error, a prize ball piece payout error, a full tank error, a card unit unconnected error, or a lending ball piece payout error is set. If at least one of these error flags is set, the firing stop signal is turned on by L04 to stop the firing motor 101, and the process is terminated.

  When none of these error flags is set, the firing motor 101 is enabled by turning off the firing stop signal at L03, and the process is terminated. Therefore, as shown in Table 2 above, this subroutine program generates a communication error, a prize ball payout excessive error, a prize ball piece payout error, a full tank error, a card unit unconnected error, or a lending ball piece payout error. The firing motor is stopped when the power is on, and the firing motor is also stopped when the initial operation stop flag for 1.6 seconds from the power-on is set.

  FIG. 21 shows a flowchart of a processing program executed by the ball payout control unit in response to a CH0 interrupt that occurs every 4 ms. First, in M01, the states of the prize ball sensors 138a and 138b and the lending ball sensors 138c and d are determined. Subsequently, it is determined whether or not a prize ball has been paid out in M02, and when a prize ball is paid out, the number of unpaid prize balls is subtracted by 1 in M03 (however, although not shown in the flowchart). If it is 0, no subtraction is performed.), The process proceeds to M04, and if no payout of a winning ball is detected, the process proceeds to M04 as it is. Subsequently, it is determined whether or not a lending ball has been paid out by M04, and when lending ball payout is detected, the number of unpaid lending balls is subtracted by 1 by M05 (however, this is not shown in the flowchart). If it is 0, no subtraction is performed.), The process proceeds to M06, and if the rental ball is not paid out, the process proceeds to M06 as it is. The number of unpaid balls is calculated by the subtraction process based on the M05 payout detection and the addition process based on the J15 payout request signal reception.

  In M06, the backup flag is cleared when the number of unpaid prize balls reaches 0 for the first time. In M07, similarly to the process shown in FIG. 14 executed by the main control unit, a process of monitoring a prize ball payout excessive error in which prize balls are paid out even though there is no unpaid prize ball number is executed. However, the transmission command shown in E07 and the prize ball LED shown in E08 are not turned on, and the counter and flag values used are stored in the RAM 803 of the ball payout controller 800.

  Subsequently, in M08, in the same manner as the process shown in FIG. 15 executed by the main control unit, a process of monitoring a prize ball payout undetected error in which no payout is made even though the number of unpaid prize balls remains is executed. . However, storage of the transmission command shown in F10 and F22, lighting of the prize ball LED shown in E12, and lighting of the prize ball LED shown in E23 are not performed, and the timer and flag values used are stored in the RAM 803 of the ball payout control unit 800. To do.

  Subsequently, at M09, a prize for monitoring a prize ball piece payout error that is detected only by one of the two prize ball sensors 138a or 138b of the ball payout apparatus 80a for the ball payout apparatus 80a for the prize ball. Executes a ball piece payout error monitoring process. Subsequently, in M10, an award for monitoring a prize ball piece payout error in which the ball payout detection of the ball payout device 80b for lending balls is performed only by one of the two prize ball sensors 138c or 138d of the ball payout device 80b. In M11, the ball piece payout error monitoring process is executed to monitor a lending ball payout non-detection error in which no payout is performed even though the number of unpaid lending balls remains.

  Subsequently, in M12, the error canceling switch 94 is monitored, in M13, the winning ball payout motor operation check process is monitored to monitor the start and stop of deceleration of the prize ball motor. In M14, the lending motor is started to decelerate. And the lending ball payout motor operation check process for monitoring the stop start is performed. Subsequently, in M15, an update process for adding 1 to the values of various timers used in the ball payout control unit 800 is performed. In M16, a process for displaying the error symbol selected in the error display selection process on the error display is performed. And exit.

  FIG. 22 is a flowchart showing a subroutine program of the prize ball piece payout error monitoring process shown in M09. First, in N01, it is determined whether or not one payout flag is set. If it is set, the process ends. If it is not set, the process proceeds to N02. In N02, it is determined whether or not a prize ball has been paid out. When no prize ball has been paid out, the process is terminated. When a prize ball has been paid out, N03 is set in R11 of the CH1 interruption process described later. The winning ball payout monitoring counter value is decremented by 1, and the process proceeds to N04.

  Then, in N04, it is determined whether or not the prize ball sensor that has detected the payout is the prize ball sensor 138a. If it is the prize ball sensor 138a, 1 is added to the first prize ball payout counter in N05, and the prize is awarded. When it is not the ball sensor 138a, 1 is added to the second prize ball payout counter by N06. In N07, it is determined whether or not the value of the payout monitoring counter is 0, that is, whether or not one segment (2 to 15 payouts) of the prize ball payout has ended. If one segment has not ended, the process ends as it is, and if one segment of prize ball payout has ended, the process proceeds to N08.

  In N08, it is determined whether or not the value of the first prize ball payout counter is 0. If it is 0, a prize ball piece payout error flag is set in N10, and if it is not 0, the process proceeds to N09. . In N09, it is determined whether or not the value of the second counter is 0. If it is 0, a prize ball piece payout error flag is set by N10, and if it is not 0, the process is ended. Therefore, according to this subroutine program, a prize ball piece payout error occurs when the payout of all the balls is detected by one of the prize ball sensors 138a or 138b in the payout of one segment of prize balls. The winning ball piece payout error flag is set.

  FIG. 23 is a flowchart showing a subroutine program of the error release switch monitoring process shown in M12. First, in P01, it is determined whether or not the backup flag is set. When it is not set, the process proceeds to P02, and it is determined whether or not the error release switch is pressed. When it is pressed, the prize ball payout non-detection error flag and the lending ball payout non-detection flag are cleared at P03. To finish.

  Therefore, if an error occurs between the time when the power is turned on after the power is turned off and the backup payout is completed after the power supply with the backup flag set, control is performed so that the error release switch is not accepted. This is because if an error occurs during the payout by the backup, the payout is stopped, and the main control unit 900 determines that the payout by the backup is completed, and starts monitoring the excessive payout payout error. When the game is resumed, the payout due to the back-up is not actually finished, so the number of prize balls remaining on the prize board is inconsistent with the number of prize balls remaining on the main board, and an excessive prize ball payout error is detected immediately. Because.

  FIG. 24 shows a flowchart of an NMI interrupt processing program executed by the ball payout control unit. When the external power supply voltage supplied to the ball payout control unit 800 drops, the drop is detected and a voltage drop signal is input from the voltage drop detection circuit 801 to the external NMI signal terminal of the CPU 804 of the ball payout control unit 800. When an error command or a payout command is transmitted from the main controller 900, a strobe signal (STB signal) is input to the external NMI signal terminal of the CPU 804. Then, when these signals are input to the external NMI signal terminal, this NMI interrupt processing is started. Since the main board is powered off earlier than the prize ball board, the command data reception process and the power-off process do not occur simultaneously. Similarly, command data reception processing does not occur after processing at power-off occurs.

  First, in Q01, it is determined whether or not there is a command input from the main control unit at the command input port of the ball payout control unit. If there is no command input, the input to the external NMI signal terminal is a power supply lowering signal. Then, the backup flag is set by Q07, the RAM 803 is prohibited from being written by Q08, and the CPU 804 reads the HALT instruction by Q09 and enters the stop state. The processes shown in Q07 to Q09 are backup processes when the power is turned off.

  On the other hand, if there is a command input in Q01, it is determined in Q02 whether or not the input command is a payout command, and if it is a payout command, the number of unpaid award balls is responded to the payout command in Q03. Add the number to be processed and finish. The number of unpaid winning balls is calculated by the addition process based on the reception of the payout command in Q02 and the subtraction process based on the payout detection in M03, and stores and manages up to a predetermined number (for example, 65535 that can be managed in a 2-byte area). Is done.

  If it is not a payout command, it is determined whether or not the command input in Q04 is an error command. If it is an error command, in Q05, a prize ball payout excessive error flag corresponding to the error command, Set or clear the ball payout undetected error flag, idle cut prevention switch error flag or full tank error flag. If the command is not an error command, an unscheduled command has been input, so a communication error flag is set in Q06 and the process ends.

  As described above, in this interrupt processing, when there is an input signal to the input port when there is an input to the NMI terminal of the CPU 804, if the input data is a payout command or an error command, the command is handled in advance. If the input data to the input port is an unscheduled command, the communication error flag is set. If there is no input signal to the input port, the power supply that holds the stored value of the RAM 803 at that time Perform backup processing at shutdown.

  FIG. 25 shows a flowchart of a processing program executed by the ball payout control unit in response to a CH1 interrupt that occurs at intervals of 2.5 ms to 10 ms. In R01, it is determined whether or not a single payout flag indicating that the number of one payout is set to 1 is set. If it is set, the process proceeds to R02 and is not set. If so, proceed to R05. In R02, one payout control is executed, and in R03, it is determined whether or not one payout has been completed. If it has not been completed, the process ends. To finish. This single payout process is accelerated when the prize ball payout motor 136a is accelerated to a medium speed and then decelerated, and is stopped when the value of the prize ball payout monitoring counter becomes zero.

  In R05, it is determined whether or not the prize ball payout monitoring counter value is 0. If it is 0, the process proceeds to R07, and if it is not 0, a plurality of payout controls are executed in R06 and the process is terminated. The plurality of payout processes are performed by accelerating the prize ball payout motor 136a and rotating it at a constant speed at a high speed, decelerating when the prize ball payout monitoring counter value becomes 1, and stopping when the count value becomes 0, This is processing for stopping the rotation of the motor 136a for 100 ms. In this manner, the payout motor 136a is controlled so that the payout interval between successive balls is 0.2 s or less including the rest time (100 ms).

  In R07, it is determined whether or not the payout motor is rotating. If it is rotating, it is determined that the motor is not ready to move to the next stage, and the process ends. On the other hand, when it is not rotating, it is determined in R08 whether or not the number of unpaid prize balls is greater than 0. If it is greater than 0, the process proceeds to R09, and if it is 0, there is no prize ball to be paid out and the process is terminated. .

  In R09, it is determined whether or not the number of unpaid prize balls is 15 or more. If the number is 15 or more, the prize ball payout monitoring counter is set to 15 in R10 and the process ends. If it is less than 15, in R11, the value of the number of unpaid prize balls is set in the prize ball payout monitoring counter, and the process proceeds to R12. Then, in R12, it is determined whether or not the value of the winning ball payout monitoring counter is 1, and if it is 1, in R13, one payout flag is set and the process ends. It ends. Therefore, by this interrupt process, if the number of unpaid prize balls is 15 or more, the number of prize balls to be paid out at one time is set to 15, and if the number of unpaid prize balls is less than 15, it is paid out once. The number of winning balls to be issued is set to the number of unpaid winning balls at that time.

  Although not shown, the ball payout control unit executes the same process as the CH1 interrupt process for the lending ball by the CH2 interrupt generated at intervals of 2.5 ms to 10 ms. However, the maximum value set in the lending ball payout monitoring counter is 15 in the CH1 interrupt process, but is 25 in the CH2 interrupt process. Therefore, if the number of unpaid balls is 25 or more by the CH2 interrupt processing, the number of balls to be paid out at one time is set to 25, and if the number of unpaid balls is less than 25, the loan is paid out at once. The number of balls is set to the number of unpaid balls at that time.

  According to the pachinko gaming machine configured as described above, when an abnormality occurs in the power supply during the game and the power supply voltage supplied from the power plug 109 is reduced or cut off, the backup flag is set, Since the RAM 803 is write-protected and the RAM 803 is supplied with power from the backup power source 802, the value at that time is stored while the backup power source supplies a predetermined voltage.

  When power supply from the power plug 109 to the gaming machine is started, the main control unit 900 initializes the RAM 903 and sets the stored value of the number of unpaid prize balls to 0. On the other hand, if the backup flag is not set at that time, the ball payout control unit 800 initializes the RAM 803 when the power is turned on, but if the backup flag is set by the backup flag processing when the power is turned off, When the power is turned on, the initial operation flag is set and the winning ball payout excess counter is reset. When the error release switch is pressed, the predetermined error flag is further cleared. Not changed. Therefore, the stored value of the number of unpaid award balls stored in the RAM 803 of the ball payout control unit 800 is held.

  Further, the ball payout control unit 800 stops the firing motor, the prize ball motor, and the lending ball payout motor for 1.6 seconds after the power-on in which the initial operation flag is set. The reason for setting the stop time to 1.6 seconds is that it takes into account the time difference between the start-up of the main board and the prize ball board, the time to receive an error occurrence / error release command from the main board, etc. is there. When the backup flag is set and the number of unpaid prize balls is not 0, the payout of the number of unpaid prize balls stored by the backup is started 1.6 seconds after the activation. In addition, a prize ball for backup is thus started.

  Here, it is assumed that the period from the start of rotation of the prize ball motor to the prize ball is 0.1 s, and even if the maximum deviation is 0.2 s, the first payout is normally at the latest from the start of the payout control unit 800. Detected after 1.9 seconds, taking into account the activation time difference (0.4 s) between the main control unit 900 and the ball payout control unit 800, it is detected before 1.5 seconds elapses from the activation of the main control unit 900. Further, the payout interval during payout of the prize ball is normally 0.2 seconds or less as described above, and therefore is within 0.3 seconds even if the maximum deviation is 0.1 seconds. Therefore, when the payout interval after the start of payout by the backup exceeds 0.3 seconds, it can be determined that the backup has ended.

  On the other hand, when the backup flag is not set and the payout by the backup is not executed, the payout of the first prize ball is detected by the prize detection means after the game ball is launched and falls into the prize opening. Since this is performed after the payout command is transmitted from the main control unit 900 to the ball payout control unit 800, the game ball is launched, dropped into the winning opening, detected by the winning detection means, and the payout command is transmitted and received. Since extra time is required, the time required from the activation of the main control unit 900 to the start of the first payout is longer than 1.5 seconds. Therefore, it is possible to detect whether or not the payout by the backup is executed based on whether or not the prize ball is paid out within 1.5 seconds from the activation of the main control unit 900.

  FIG. 26 is a time chart for explaining the operation of the pachinko gaming machine according to the present embodiment when the power is turned on when the number of unpaid prize balls stored and held by the backup is, for example, 13. In this case, it is assumed that there is no winning in the period shown in the time chart. When activated at time t1, the ball dispensing control unit 800 stops the award ball dispensing motor 136a and the firing motor 101 for 1.6 seconds, and then turns off the firing motor stop signal to make the firing motor 101 movable at time t3. . Further, since it is stored that the number of unpaid prize balls is 13 by the process when the power is cut off, the prize ball motor 136a is rotated from time t3 to start paying out 13 prize balls.

  On the other hand, the main control unit 900 starts at time t2 with a delay of 0.4 s from the time t1, and detects the payout of the first prize ball at time t4 which is within 1.5 seconds thereafter. The first ball monitoring end flag is set. While the 13 winning balls are being paid out, the winning ball payout detection interval does not exceed 0.3 seconds, and therefore the condition for setting the second and subsequent balls monitoring processing end flag is not satisfied. When the monitoring process end flag is not set, and the payout of the 13 winning balls by the backup at time t6 is finished, the number of unpaid winning balls stored in the payout control unit 800 becomes 0, and the payout of the winning balls is stopped. Since the ball payout detection interval is 0.3 seconds or longer, the second ball and subsequent monitoring end flag is set at time t7 after 0.3 seconds from the time t6 when the payout detection of the thirteenth prize ball is detected, and the prize ball Set the excessive payout error monitoring execution flag.

  Accordingly, the main control unit 900 receives a prize ball from time t2 to time t7 when the number of unpaid prize balls stored in the main control section 900 and the number of unpaid prize balls stored in the payout control section 800 coincide with each other in order to prevent erroneous detection. Although the payout excessive error monitoring process is not executed, after the time t7 when both the number of unpaid prize balls stored in the main control unit 900 and the number of unpaid prize balls stored in the payout control unit 800 become 0, an excessive prize ball payout error is detected. Execute monitoring processing. The unpaid winning ball number stored in the main control unit 900 and the unpaid winning ball number stored in the payout control unit 800, which are once equalized in this way, are added when a winning is detected, and a payout is detected. Since it is subtracted and changes at the same value, it is possible to accurately detect a prize ball payout excessive error.

  FIG. 27 illustrates the operation of the pachinko gaming machine according to the present embodiment when the power is turned on when the backup flag is not set or when the number of unpaid prize balls stored and retained by the backup is zero. It is a time chart. In this case, it is assumed that immediately after the power is turned on, the launch lever is operated, the game ball is fired on the game board surface, and the winning opening is won. When started at time t1, the ball payout controller 800 stops the prize ball payout motor for 1.6 seconds and then moves the prize ball payout motor at time t3. At this time, the number of unpaid prize balls is 0. Since there is a prize ball, the first game ball is detected at time t9 because the game ball that has been launched wins and is detected by the winning sensor and the payout of the prize ball starts at time t8. Is done. This time t9 is later than the time t5.

  The main controller 900 starts at the time t2 later than the time t1, and does not detect the payout of the award ball even after 1.5 seconds have elapsed, so at the time t5, the first ball monitoring end flag, the second ball A monitoring end flag and a prize ball payout excessive error monitoring execution flag are set. Thus, when the power is turned on, the number of unpaid prize balls stored in the main control unit 900 and the number of unpaid prize balls stored in the payout control unit 800 are both 0 and coincide with each other. From time t5, the prize ball payout excessive error monitoring process is started. Then, the first prize ball paid out by winning after the power is turned on is detected at time t8 after time t5. In this case, at time t5, the number of unpaid prize balls stored by the main control unit 900 and the number of unpaid prize balls stored by the payout control unit 800 are both 0. Since it is added when it is done and subtracted when a payout is detected, it changes at the same value. Therefore, it is possible to accurately detect a prize ball payout excessive error from time t5.
