Description

It relates to a gaming machine having a random number generator.

  In a gaming machine equipped with a random number generator, a random number value of a predetermined number of digits is generated by a clock count circuit based on a clock generated at a predetermined cycle by a random number clock generation circuit composed of an oscillator such as a crystal resonator or an oscillator. The CPU which controls the game periodically extracts the count value stored in the count value storage circuit and reads it, and uses the read count value as a random number for determination of the lottery or identification information content. I use it. By using a random number generator that counts random values by hardware as described above, the software load is reduced as compared with the case where software controlled by the CPU executes a program and counts random values. Random numbers can be generated and updated at high speed according to the clock generation cycle of the clock generation circuit (Japanese Patent Laid-Open Nos. 2003-190483 and 7-124296).

  However, in a gaming machine using a random number generator that counts random values by hardware as described above, a random number clock generator (oscillator) that constitutes the random number generator, or a clock count that also constitutes the random number generator. When some abnormal operation occurs in the circuit, the random number value may not be counted periodically and may be stopped. In such a state, the CPU repeatedly reads the same count value stored in the count value storage circuit. And even if it falls into such a state, since a game machine continues operation | movement without alert | reporting abnormal operation | movement, it was hard to notice abnormal operation | movement of a random number generation part. At this time, if the random number for lottery that is disadvantageous for the game hall is repeatedly read by the player continuing the game as it is, damage is caused to the side of the game hall, while random numbers for lottery that are disadvantageous for the player are repeatedly read. If this happens, damage to the player has occurred. In addition, when any failure occurs in the random number generator, it is difficult to determine whether this failure is due to abnormal operation in the random number clock generation circuit (oscillator) or abnormal operation in the clock count circuit. was there.

Therefore, Patent Document 1 proposes a gaming machine that can detect an abnormal operation in a random number clock generation circuit and a clock count circuit that constitute a random number generation unit, determine an abnormal part, and notify this at an early stage. Yes.

And an error display device 61, a speaker 45, and the like, which are electrically connected by a cable or the like.

  The main board 700 includes a system unit that manages the entire operation of the pachinko machine PM, a storage unit that is preliminarily stored with a game execution program, and a microprocessor that executes these programs (hereinafter, “ A main control unit 730 having a CPU) and a random number generation unit 750 for generating random numbers for lottery (65536 random numbers from 0 to 65535) regardless of the control of the main board 700. . In the present invention, the random number values counted by the clock count circuits B81 to B84, which will be described later, and stored in the first and second count value storage circuits B91 and B92 will be specifically referred to as “count values”. In the best mode, only the winning random number is acquired as a hard random number, and other random numbers (for example, a random number for determining symbols and a random number for determining a variation mode) are acquired as soft random numbers (pseudo random numbers). However, the present invention is not limited to this, and the random numbers subject to the present invention are random numbers related to the main game (for example, symbol determination random numbers and variation mode determination random numbers for special symbols), random numbers related to auxiliary games (for example, winning symbols for normal symbols) Random number) or a random number related to the effect on the sub-board side (for example, a random number for determining a stop symbol for a decorative symbol, a random number for determining a variation mode, or a random number for determining whether or not to give a notice).

  The control unit 740 in the main control unit 730 is provided with a ROM and a RAM in addition to the CPU described above, and a control program to be executed by the CPU and data necessary for the control process are described in the ROM. The main control unit 730 is provided with a reference clock generation circuit 731. The reference clock generation circuit 731 is a circuit that generates a reference clock that is an operation reference of the CPU that plays a central role in the control of the pachinko machine PM. ). In addition, the reference clock may be obtained by appropriately dividing the pulse by the frequency divider 735. The functions that the control unit 740 has through program execution will be described later.

  In addition, the error display device 61 and the speaker 45 are connected to the main board 700 via wiring cables, respectively, and by a control signal supplied from the control unit 740 that detects an abnormality in each circuit board such as the main board 700, In the error display device 61, the first error display unit 61a or the second error display unit 61b can be turned on and the speaker 45 can emit sound.

  Here, with reference to FIG.4 and FIG.5, the structure of the part which concerns on generation | occurrence | production of the random number in the pachinko machine PM, and this extraction is demonstrated. The input circuit unit B40 is a part to which input information from outside the main substrate 700, a random number generated by a random number generation unit 750 provided in the main substrate 700, and an abnormal signal from a clock monitoring circuit B95 described later are input. For example. Specifically, the input circuit unit B40 receives from the first start prize sensor 51 or the second start prize sensor 52 output according to the winning of the hit ball to the first start prize port 24a or the second start prize port 24b. And the upper and lower 8 bits of the random number generated by the random number generator 750 are input. Further, an output signal from a random number clock generating means B51, which will be described later, is input to the input circuit section B40, and whether or not this output signal is a pulse signal due to normal operation of the random number clock generating means (circuit) B51 is input. It is monitored by the control unit 740 via the circuit unit B40.

  The output circuit unit B45 receives a read signal for reading a signal such as a control signal to an electrical component (lamp, speaker, etc.) outside the main board 700 and a random number generated by the random number generator 750 provided in the main board 700. The output part is composed of an IC such as a buffer. Specifically, when the main circuit board 700 determines that the first start winning opening 24a has won a prize from the output circuit unit B45, the first read signal that triggers the reading of the count value corresponding to this prize, When the main board 700 determines that there is a winning at the second start winning opening 24b, a second reading signal that triggers reading of the count value corresponding to the winning is output. Further, when an abnormal operation is detected in the random number clock generation means B51 or the clock count circuits B81 to B84, a control signal is output to the error display device 61 to display a predetermined error.

  Here, as shown in FIG. 5, the first start signal from the first start winning sensor 51 is input to the 1A terminal of the IC 14 of the input circuit unit B40. On the other hand, the second start signal from the second start winning sensor 52 is input to the 2A terminal of the IC 14 of the input circuit unit B40. Further, the 3A terminal of the IC 14 is connected to the collector of the transistor TR1 constituting the clock monitoring circuit B95. When a voltage is applied to the base of the transistor TR1, a collector current flows from the input circuit section B40 side. Yes.

  The random number generator 750 generates a count value used as a random number. Specifically, the random number generator 750 includes a random number clock generation circuit B51, a random number clock inversion circuit B61, first and second latch signal output circuits B71, B72, The first to fourth clock count circuits B81, B82, B83, B84, first and second count value storage circuits B91, B92, a clock monitoring circuit B95, and an overflow signal output circuit B97 are configured.

  The random number clock generation circuit B51 (OSC1) is for generating a clock for counting random numbers, and includes a clock output unit (OUT) for outputting the generated clock. The random number clock generation circuit B51 is constituted by, for example, a crystal oscillator that generates a 7.15909 MHz clock.

  The random number clock inversion circuit B61 (IC18) inverts the clock output from the random number clock generation circuit B51, and uses this as an inverted clock to be described later as a first latch signal output circuit B71 (IC16) and a second latch signal output circuit. The data is output to B72 (IC17). Specifically, in the IC 18, a signal obtained by inverting the signal output from the 1Q terminal is output as an inverted signal from the 1Q inverting terminal that is the inverted clock output unit, and the rising edge of the clock is the falling edge of the inverted clock. The falling edge of the clock corresponds to the rising edge of the inverted clock. The random number clock inverting circuit B61 may be configured using an IC such as a NOT gate.

  The first to fourth clock count circuits B81, B82, B83, and B84 each have a random number clock input unit (CK) that inputs a clock and a count output unit (QA to QD) that outputs the counted value. ing. As shown in FIG. 5, the first to fourth clock count circuits B81, B82, B83, and B84 are constituted by a circuit in which four 4-bit increment counters (from IC1 to IC4) are cascade-connected to generate a random number clock. This is a circuit for adding at the rising edge of the clock generated by the circuit B51 and outputting the addition result.

  In response to the input of the clock from the random number clock generation circuit B51, first, the first clock count circuit B81 (IC1) counts a value for four digits (for example, “0001” and “0011”). When "1111" is counted and the count of four digits ends, a carry signal is output from the CO terminal of IC1 to the ENT terminal of the second clock count circuit B82 (IC2) each time. In order for the second clock count circuit B82 to start counting, it is necessary to input the carry signal from the first clock count circuit B81. That is, in the IC2, counting of the next four digits is started only when the carry signal and the clock (input to the CK terminal) from the random number clock generation circuit B51 are simultaneously input.

  Similarly, when a value for four digits (for example, “0001” or “0011”) is counted up to “1111” in IC2, a carry signal is sent from the CO terminal of IC2 to the third clock count circuit B83 each time. It is output to the ENT terminal of (IC3). In order for the third clock count circuit B83 to start counting, it is necessary to input the carry signal from the second clock count circuit B82. That is, in the IC 3, the count of the next four digits starts only after the carry signal and the clock (input to the CK terminal) from the random number clock generation circuit B 51 are input simultaneously.

  Similarly, when a value for four digits (for example, “0001” or “0011”) is counted up to “1111” in IC3, the carry signal is counted from the CO terminal of IC3 to the fourth clock each time. It is output to the ENT terminal of the circuit B84 (IC4). In order for the fourth clock count circuit B84 to start counting, it is necessary to input the carry signal from the third clock count circuit B83. That is, in the IC4, the count of the next four digits starts only after the carry signal and the clock from the random number clock generation circuit B51 (input to the CK terminal) are input simultaneously.

  As described above, 16-bit binary numbers are generated by the clock count circuits B81 to B84. That is, among the 16-digit binary numbers, the first clock count circuit B81 (IC1) is the lowest four digits, the second clock count circuit B82 (IC2) is the upper four digits, and the third clock count circuit B83 (IC3 ) Is further responsible for the upper 4 digits and the fourth clock count circuit B84 (IC4).

  The counts added by the four clock count circuits B81 to B84 are sent to the first count value storage circuit B91 and the second count value storage circuit B92 via the respective count output sections (QA, QB, QC and QD terminals). Each is output and stored. In this embodiment, an addition-type increment counter is used as the clock count circuit. However, in other embodiments, a subtraction-type decrement counter may be used. In this embodiment, a 16-bit random number (4 bits × 4) is generated. However, in other embodiments, the number of bits is not limited to 16 bits and may be changed as appropriate. .

  The latch signal output circuits B71 and B72 include a first latch signal output circuit B71 (IC16) for acquiring a random number associated with winning in the first start winning opening 24a and a random number associated with winning in the second starting winning opening 24b. The second latch signal output circuit B72 (IC17) related to acquisition is divided.

  The inverted clock from the random number clock inverter circuit B61 (IC18) is input to the first latch signal output circuit B71 (IC16) via the first inverted clock input section (1CK). At the same time, the first start signal from the first start winning sensor 51 is input to the first start signal input unit (1D) via the buffer (IC13). When the first start signal (low signal) is input via the first start signal input section (1D), the first latch signal output circuit B71 uses the rising edge of this signal as the first inverted clock input. The first count value storage circuit B91 (IC5 and IC6) passes through the first latch signal output unit (1Q) as the first latch signal after being delayed in synchronization with the rising edge of the inverted clock input from the unit (1CK). Output to.

  On the other hand, the second latch signal output circuit B72 (IC17) receives the inverted clock from the random number clock inverter circuit B61 via the second inverted clock input section (2CK). At the same time, the second start signal from the second start winning sensor 52 is input to the second start signal input unit (2D). When the second start signal (low signal) is input through the second start signal input unit (2D), the second latch signal output circuit B72 sends the rising edge of this signal from the inverted clock input unit. After being delayed so as to be synchronized with the rising edge of the input inverted clock, the second latch signal is output to the second count value storage circuit B92 (IC7 and IC8) via the second latch signal output unit (2Q).

  The first and second start signals are also input to the main control unit 730 via the input circuit unit B40 and the like, as will be described later, and may be used as a timing for starting a program executed for random number acquisition. It is supposed to be used.

  The count value storage circuits B91 and B92 are a first count value storage circuit B91 for temporarily storing a random number derived from winning in the first start winning opening 24a and a random number derived from winning in the second starting winning opening 24b. Is divided into a second count value storage circuit B92 for temporarily storing.

  The first count value storage circuit B91 calculates the count value counted by the clock count circuits B81 to B84 based on the first latch signal from the first latch signal output circuit B71 (the first count from the first start winning sensor 51). When a start signal is received and a latch signal is output from the first latch signal output circuit B71, it is stored. On the other hand, the second count value storage circuit B92 calculates the count value counted by the clock count circuits B81 to B84 based on the second latch signal from the second latch signal output circuit B72 (from the second start winning sensor 52). The second start signal is received and stored (when a latch signal is output from the second latch signal output circuit B72).

  As shown in FIG. 5, the first count value storage circuit B91 includes a register unit (IC5 and IC6) including two 8-bit ICs and a buffer unit (IC9 and IC10) including two 8-bit ICs. The Similarly, the second count value storage circuit B92 includes a register unit (IC7 and IC8) including two 8-bit ICs and a buffer unit (IC11 and IC12) including two 8-bit ICs.

  Of the register portion of the first count value storage circuit B91, the IC5 receives the 4-digit count value from the first clock count circuit B81 (IC1) through the D1 terminal to the D4 terminal, The 4-digit count value from the clock count circuit B82 (IC2) is input via the D5 terminal to the D8 terminal. In other words, the D1 terminal to D8 terminal of the IC5 function as a count input unit, and the lower 8 digits of the 16-bit binary count value derived from the first start winning port 24a are input to the IC5 through these terminals. .

That is, the D8 terminal to D8 terminal of the IC8 function as a count input unit, and the IC8 receives the upper 8 digits of the 16-bit binary count value derived from the second start winning port 24b through these. The

  The first latch signal from the first latch signal output circuit B71 is input to the CLOCK terminal in the register unit (IC5 and IC6) of the first count value storage circuit B91. That is, these CLOCK terminals function as a first latch signal input unit, and at the time of the rising edge when the first latch signal input from the first latch signal input unit becomes a high signal, the clock count circuit B81. The count value input from ~ B84 is stored in the register unit.

  The second latch signal from the second latch signal output circuit B72 is input to the CLOCK terminal in the register unit (IC7 and IC8) of the second count value storage circuit B92. That is, these CLOCK terminals function as a second latch signal input unit, and at the time of the rising edge when the second latch signal input from the second latch signal input unit becomes a high signal, the clock count circuit B81. The count value input from ~ B84 is stored in the register unit.

  The G1 terminal in the buffer unit (IC9 and IC10) of the first count value storage circuit B91 corresponds to a read signal output from the output circuit unit B45 of the main control unit 730 based on a program executed for obtaining random numbers. Thus, one count value consisting of 16 digits stored in the first count value storage circuit B91 is output to the CPU (control unit 740). That is, at the time of the falling edge when the read signal input from the read signal input unit becomes a low signal, the random numbers stored in the register units (IC5 and IC6) are transferred to the CPU via the Y1 terminal to Y8 terminal, respectively. Output to the data bus.

  Of the random numbers output from the first count value storage circuit B91, those passing through the IC 9 are input to the CPU (control unit 740) and handled as the lower 8 digits of the 16-digit random number. It becomes. On the other hand, among the random numbers output from the first count value storage circuit B91, those passing through the IC 10 are input to the CPU (control unit 740) and handled as the upper 8 digits of the 16-digit random numbers. It becomes.

  The terminal G1 in the buffer unit (IC11 and IC12) of the second count value storage circuit B92 stores the second count value according to the read signal output from the output circuit unit B45 of the main control unit 730 based on the program. One count value of 16 digits stored in the circuit B92 is output to the CPU (control unit 740). That is, at the time of the falling edge when the read signal input from the read signal input unit becomes a low signal, the random numbers stored in the register units (IC7 and IC8) are transferred to the CPU data via the Y1 terminal to Y8 terminal, respectively. Output to the bus.

  Among the random numbers output from the second count value storage circuit B92, those passing through the IC 11 are input to the CPU (control unit 740) and handled as the lower 8 digits of the 16-digit random number. . On the other hand, among the random numbers output from the second count value storage circuit B92, those passing through the IC 12 are input to the CPU (control unit 740) and handled as the upper 8 digits of the 16-digit random numbers. It becomes.

  Further, in the fourth clock count circuit B84 (IC4), every time the random number value for 16 bits is counted (every bit value becomes “1”), the count from the fourth clock count circuit B84 is counted. A signal (for example, a high signal) is output from the CO terminal of IC4 toward the 1CK terminal of overflow signal output circuit B97. The count signal is stopped when the first clock count circuit B81 starts counting the random number value again (that is, the count signal is switched to the low signal).

  On the other hand, when any trouble occurs in the first to fourth clock count circuits B81 to B84, the random number value is not normally counted up in any of the first to fourth clock count circuits B81 to B84. The count signal output from the CO terminal of IC4 to the 1CK terminal of overflow signal output circuit B97 remains a low signal.

  The overflow signal output circuit B97 is configured such that the first to fourth clock count circuits B81 to B84 operate normally, and the CO of the fourth clock count circuit B84 is output every predetermined period when the 16-bit random number count ends. When a count signal as a high signal output from the terminal is input, an overflow signal as a high signal is output from the 1Q terminal toward the CPU (control unit 740). In contrast, when the abnormal operation occurs in any of the first to fourth clock count circuits B81 to B84, the count signal output from the CO terminal of the fourth clock count circuit B84 remains a low signal. The overflow signal output circuit B97 outputs an overflow signal as a low signal from the 1Q terminal to the CPU (control unit 740).

  When the CPU (control unit 740) detects that the overflow signal is a high signal in the random number monitoring process described later, all of the first to fourth clock count circuits B81 to B84 are operating normally. The control signal is output to the overflow signal output circuit B97, and the overflow signal output from the overflow signal output circuit B97 is reset to a low signal.

  On the other hand, when the CPU (control unit 740) detects that the overflow signal output from the overflow signal output circuit B97 remains a low signal in the random number monitoring process described later, the first to fourth clock counts. It is determined that any one of the circuits B81 to B84 is causing an abnormal operation.

  As described above, the random number clock generation circuit B51 generates a random number clock of about 7 MHz. Then, the clock count circuits B81 to B84 count 65536 16-bit random numbers and output the count signal to the overflow signal output circuit B97. The overflow signal is output from the overflow signal output circuit B97 to the CPU (control unit 740). The cycle is on the order of 10 ms or less (this is approximated as follows). That is, when the random number clock generation cycle by the random number clock generation circuit B51, about 0.14 μs, is multiplied by the number of 16-bit count values (65536) counted up by the normally operating clock count circuits B81 to B84, the count is performed. The signal generation cycle (which is also the generation cycle of the overflow signal as a high signal) can be calculated. }, If the random number clock generation circuit B51 is operating normally, an overflow signal as a high signal is always output in a cycle of the order of 10 ms or less. Therefore, if the overflow signal output from the overflow signal output circuit B97 is monitored at a period longer than 10 ms, it can be reliably detected whether or not the random number clock generation circuit B51 is operating normally.

  Next, the clock monitoring circuit B95 will be described together with FIG. 6 which is an enlarged view of the clock monitoring circuit B95 in the random number generation unit 750. The clock monitoring circuit B95 for monitoring the abnormal operation of the clock generation circuit B51 is composed of capacitors C3 and C4, diodes D1 and D2, a transistor TR1 and the like. The capacitor C3 is connected to the 1Q terminal of the random number clock inverting circuit B61 as a coupling capacitor, and the collector side of the transistor TR1 is connected to the 3A terminal of the input circuit unit B40. The collector side of the transistor TR1 is also connected to the positive side of the power supply E via a resistor R6. The diode D1 and the resistor R5 are both for keeping the cathode side of the diode D1 at a positive potential.

  The capacitor C3 has a role of passing only a periodic pulse signal (clock signal) from the clock generation circuit B51 from which the DC component has been cut to the clock monitoring circuit B95 side. For this reason, when the clock generation circuit B51 stops operating (pulse oscillation is stopped) due to some trouble occurring in the clock generation circuit B51, the clock generation circuit B51 outputs a constant high signal or low signal that does not change with time. Thus, the output signal from the clock generation circuit B51 is not transmitted to the clock monitoring circuit B95 side. That is, the input signal input to the clock monitoring circuit B95 changes according to the operating state of the clock generation circuit B51.

  The smoothing circuit unit B96 configured in the clock monitoring circuit B95 smoothes the pulse signal input from the clock generation circuit B51 and always outputs a voltage higher than a predetermined value (for example, 5 V or more). A diode D2 connected as an anode, a smoothing capacitor C4 connected between the cathode of the diode D2 and the ground, and the like. The diode D2 is for always holding the cathode side at a positive potential. Further, the smoothing capacitor C4 smoothes the pulse signal that has passed through the diode D2 and always outputs a voltage higher than a predetermined value, and this output voltage is applied to the transistor TR1 as a base voltage.

  The collector side of the transistor TR1 is connected to the 3A terminal of the (IC14) of the input circuit unit B40. As described above, the branch line branched from the circuit to the input circuit unit B40 is connected to the power supply E via the resistor R6. Connected to the positive side. In a state where the clock generation circuit B51 normally oscillates a pulse signal, an output voltage equal to or higher than a predetermined level smoothed by the smoothing circuit portion B96 is applied to the transistor TR1 as a base voltage. When a predetermined base voltage (for example, 5 V) is applied to the transistor TR1, a collector current Ic flows from the collector side to the emitter side (ground side) of the transistor TR1.

  The collector current Ic is supplied from the power supply E. When a current flows from the power supply E to the collector side of the transistor TR1, the current Ia does not flow toward the input circuit section B40 (IC14). At this time, the abnormal signal (first abnormal signal) indicating the abnormal operation of the clock generation circuit B51 is not output from the IC 14 to the CPU (control unit 740), and the low signal indicating the normal operation of the clock generation circuit B51. Is output. The control unit 740 determines that the clock generation circuit B51 is operating normally by detecting the low signal from the IC 14.

  On the other hand, when an abnormal operation occurs in the clock generation circuit B51 and the oscillation of the pulse signal is stopped, no voltage is applied from the smoothing circuit portion B96 to the transistor TR1, and the base voltage is zero (below a predetermined value). Collector current Ic does not flow. For this reason, the current Ia flows from the power source E toward the input circuit section B40 (IC14). When the current Ia flows through the IC 14, a high signal as an abnormal signal is output from the IC 14. When detecting a high signal from the IC 14, the control unit 740 determines that an abnormal operation has occurred in the clock generation circuit B51.

  As described above, the transistor TR1 serves as a switch that allows the current supplied from the power source E to flow to the clock monitoring circuit B95 or cuts off the current. When the current Ia flows, the control unit 740 can determine the abnormal operation of the clock generation circuit B51 by outputting an abnormal signal from the IC 14 via the CPU data bus to the CPU (control unit 740).

  7 and 8 are waveform diagrams showing temporal changes in signal waveforms in the clock generation circuit B51, the clock monitoring circuit B95, and the input circuit unit B40. 7 and 8, Va represents a clock signal (pulse signal) output from the clock generation circuit B51 and input to the clock monitoring circuit B95. Vb represents the cathode side output of the diode D1 of the input signal that has passed through the coupling capacitor C3.

  As shown in FIG. 7, the clock generation circuit B51 operates normally until the time point a and the pulse signal is oscillated toward the clock monitoring circuit B95. Therefore, Vb has the same pulse as the input waveform to the clock monitoring circuit B95. Signal.

  On the other hand, when a low signal is output from the clock generation circuit B51, the oscillation of the pulse signal is stopped at the time point a, and after that, a constant low signal that does not change with time is output from the clock generation circuit B51. The signal does not pass through the capacitor C3, and the cathode side output Vb of the diode D1 becomes zero.

Vc shows the base voltage of the transistor TR1 which is smoothed by the smoothing circuit B96, the transistor TR1 is made to flow the collector current Ic when the base voltage Vc is greater than or equal _to V ₀ (e.g., more than 5V) it is. As shown in FIG. 7, until a time point a, a base voltage equal to or higher than V _{0 is} always applied to the transistor TR1 due to the input of the pulse signal to the clock monitoring circuit B95. Ic flows. On the other hand, after the time point a, the pulse signal does not pass through the capacitor C3 and the pulse signal is not output to the cathode side of the diode D1, so the base voltage Vc of the transistor TR1 becomes V ₀ or less and the collector current Ic flows. Absent.

As described above, when the collector current Ic does not flow from the power source E toward the transistor TR1, a current flows from the power source E toward the IC 14, and an abnormal signal is output from the IC 14 toward the CPU (control unit 740). It is supposed to be. As shown in FIG. 7, the abnormal signal Vd is not output (a low signal is output) until time point a when a base voltage equal to or higher than V ₀ is generated in the transistor TR1. On the other hand, after the time point “a” when the base voltage of the transistor TR1 becomes V ₀ or less, the abnormal signal Vd is output (a high signal is output).

  When the control unit 740 detects the output of the abnormal signal Vd, the control unit 740 determines that an abnormal operation has occurred in the clock generation circuit B51 and outputs a control signal, so that the pachinko machine PM is output at a predetermined timing. The game operation is stopped and the launch is forcibly stopped, and the first error display unit 61a of the error display device 61 is turned on and sound is emitted from the speaker 45 to notify the abnormal operation of the clock generation circuit B51. Can do.

On the other hand, as shown in FIG. 8, the pulse signal oscillation stops at the time point b when the high signal is output from the clock generation circuit B51, and thereafter, a constant high signal that does not change with time is generated from the clock generation circuit B51. The same applies to the case where the signal is output, and the abnormal signal Vd is not output until the time point b at which the base voltage equal to or higher than V ₀ occurs in the transistor TR1 (a low signal is output). On the other hand, after the time point b when the base voltage of the transistor TR1 becomes V ₀ or less, the abnormal signal Vd is output (a high signal is output).

  As described above, the control unit 740 detects whether the clock generation circuit B51 is operating normally by detecting the abnormal signal Vd output from the input circuit unit B40 according to the operation state of the clock generation circuit B51. The control unit 740 can make a determination.

  Next, the function of the control unit 740 will be described in detail with reference to FIG. 3 again. First, the control unit 740 includes a game control unit 1100 that controls the main control relating to the main game and the auxiliary game, an information transmission unit 1200 that controls transmission of various types of information such as commands to the game peripheral device, and a game to various winning awards.

Here, in this best mode, the number of time reductions is 100, and during the time reduction, the variation time of the special symbol is relatively shortened (time reduction function) compared to non-time reduction. Furthermore, the fluctuation time of the normal symbol is also relatively shortened, and the opening extension time of the electric accessory of the first start winning opening (first special figure starting port) 24a is relatively extended (opening time extension function). ). The above-mentioned specific game end condition determining means 1181 has a function of determining whether or not the number of ends has been reached in a probability variation game with a limited number of times, for example (has a number variation probability variation game function). (In the case of a pachinko machine), it may have a function of performing a lottery transition from a specific game (for example, a probability variation game or a time-reduced game) to a normal game with a predetermined probability every time a symbol changes (has a falling lottery function) For pachinko machines).

  Next, the game state temporary storage means 1190 includes a main game state temporary storage means 1191 for temporarily storing the current game state in the main game, and an auxiliary game state temporary for temporarily storing the current game state in the auxiliary game.

Special figure information temporary storage means 1191b for temporarily storing stop symbols and variation mode information related to the game, and special games for temporarily storing information relating to special games (number of rounds, number of winning game balls in an arbitrary round, etc.) Related information temporary storage means 1191c.

  The auxiliary game state temporary storage means 1192 also temporarily stores auxiliary game related information for temporarily storing information related to the auxiliary game (for example, on / off information of various flags such as a normal symbol winning flag, a release extension flag, and a time reduction flag). Means 1192a and temporary figure information temporary storage means 1192b for temporarily storing information such as stop symbols and the like related to the currently changing normal symbol (normal symbol for which the change start condition is satisfied).

  Next, the random number abnormality occurrence control means 1400 has an abnormal signal output presence / absence determination means 1410 for monitoring whether or not an abnormal signal is output from the random number generation section 750, and an abnormal signal is output from the random number generation section 750. When the timing for executing the abnormality handling is reached, the abnormality handling necessity determining means 1420 for deciding to execute the abnormality handling process and the abnormality handling necessity determining means 1420 determine that the abnormality handling should be executed. , An abnormality handling unit 1430 for executing various controls for taking an abnormality handling measure, and a random number abnormality occurrence related information temporary storage unit 1440 for temporarily storing information related to the random number abnormality. Here, when an abnormality occurs in the random number generation unit 750, the abnormality handling unit 1430 stops the progress of the game (for example, does not shift to the next symbol variation, does not shift to the special game), game progress stopping unit 1431, Game ball launch prohibiting means 1432 that controls to forcibly stop launching into the game area regardless of the operation of the operation handle 8 and control for notifying an error on the error display device 61 when an abnormality occurs in the random number generator 750 And an error notification unit 1433 for executing. The dotted line encircled portion relates to a modified example, which will be described later.

  Next, the flow of processing of the pachinko gaming machine according to the best mode will be described with reference to the flowcharts of FIGS. First, FIG. 9 is a main flowchart showing a flow of general processing performed by the main control unit 730 of the main board 700. First, in step 1050, the main control unit 730 of the main board 700 executes a random number monitoring process described later. Next, in step 1100, the main control unit 730 of the main board 700 executes a normal symbol winning random number acquisition process described later. Next, in step 1200, the main control unit 730 of the main board 700 executes an electric chew drive determination process described later. Next, in step 1300, the main control unit 730 of the main board 700 executes a special game content determination random number acquisition process described later. Next, in step 1400, the main control unit 730 of the main board 700 executes a special symbol display process described later. Next, in step 1500, the main control unit 730 of the main board 700 executes a special game operation condition determination process described later. Next, in step 1600, the main control unit 730 of the main board 700 executes a special game execution process described later. Next, in step 1800, the main control unit 730 (especially the prize ball payout determining means 1300) of the main board 700 drives the prize ball payout device 3000 based on the winning opening where the game ball has won, to obtain a predetermined number of prize balls. The payout process is performed, and the process returns to step 1100 again. Hereinafter, processing related to each subroutine will be described in detail.

  Next, FIG. 10 is a flowchart of the random number monitoring process according to the subroutine of Step 1050 in FIG. First, in steps 1052 to 1058, an abnormal signal reception process from the random number generator 750 is executed. Specifically, first, in step 1052, the abnormal signal output presence / absence determining unit 1410 determines whether or not the first abnormal signal is received from the random number generator 750. Here, the first abnormal signal in this best mode is a case where a high signal from the IC 14 is detected (as described above, when the abnormal operation occurs in the clock generation circuit B51 and the pulse signal is in the oscillation stopped state). , A high signal is output from the IC 14). In the case of Yes in step 1052, in step 1054, the abnormality signal output presence / absence determination unit 1410 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440 and turns on the first abnormality confirmation flag. Next, at step 1056, the abnormal signal output presence / absence determining means 1410 determines whether or not a second abnormal signal has been received from the random number generator 750. Here, the second abnormal signal in the best mode is a case where the overflow signal is a low signal for a predetermined period of time (as described above, if the clock count circuits B81 to B84 are functioning normally, If an overflow signal is periodically output as a high signal and only a low signal is output for a longer period of time than the periodic signal, this is an abnormality of the clock count circuit or the clock generation circuit). In the case of Yes in step 1056, in step 1058, the abnormality signal output presence / absence determination unit 1410 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440, turns on the second abnormality confirmation flag, and proceeds to step 1068. . Above, the abnormal signal reception process from the random number generation part 750 is complete | finished.

  Next, in step 1060 to step 1066, processing is executed when an abnormal signal is no longer received in a situation where an abnormal signal has been received in the past. Specifically, first, in the case of No in step 1052, that is, when the first abnormal signal has not been received, in step 1060, the abnormal signal output presence / absence determining means 1410 generates a random number abnormality. With reference to the flag area of the related information temporary storage unit 1440, it is determined whether or not the first abnormality confirmation flag is on. In the case of Yes in Step 1060, in Step 1062, the abnormality signal output presence / absence determination unit 1410 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440, turns off the first abnormality confirmation flag, and proceeds to Step 1056. . In the case of No in step 1056, that is, when the second abnormal signal has not been received, in step 1064, the abnormal signal output presence / absence determining means 1410 is a random number abnormality occurrence related information temporary storage means. With reference to the flag area 1440, it is determined whether or not the second abnormality confirmation flag is ON. In the case of Yes in Step 1064, in Step 1066, the abnormality signal output presence / absence determination unit 1410 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440, turns off the second abnormality confirmation flag, and proceeds to Step 1068. . The process in the case where the abnormal signal is no longer received under the situation where the abnormal signal has been received in the past is ended. In the case of No in step 1060, the process proceeds to step 1056. On the other hand, if NO in step 1064, the process proceeds to step 1068.

  Finally, step 1068 to step 1070, which are features of the best mode, will be described. In this best mode, as is understood from the fact that the random number monitoring process is continuously executed in the main routine on the main board side in FIG. 9, the random number is constantly monitored. Then, as described above, an abnormality confirmation flag is set when an abnormality signal from the random number generator 750 is detected. After that, as will be described later, when it is determined that the abnormality confirmation flag is set at the time when the game is not executed or when the symbol variation is finished, the game is progressed after setting the abnormality handling flag. Processing for stopping is executed (steps 1904 to 1918 in FIG. 15). Here, in this best mode, a loop process is executed so that the game does not proceed (a loop in step 1918 in FIG. 15). This loop processing ends when the power is turned off, and when the power is turned on again, the random number monitoring processing in step 1050 is executed again. Here, when the power is turned on in a state where the RAM is not cleared, the abnormality handling flag that was turned on in step 1916 in FIG. 15 remains on. Considering this situation, step 1068 to step 1070 in FIG. 10 will be described. In step 1068, the random number abnormality occurrence occurrence control means 1400 refers to the flag area of the random number abnormality occurrence related information temporary storage means 1440. Then, it is determined whether the abnormality handling flag is off. In the case of Yes in step 1068, in step 1069, whether or not the random number abnormality occurrence control means 1400 is currently playing a game (for example, a symbol stop state, a special game non-execution state, a game ball launch stop state). Determine whether or not. Here, in the case of Yes in Step 1069, the process proceeds to the next process (ordinary symbol winning random number acquisition process 1100). However, in the case of No in Step 1068, the random number abnormality occurrence control means 1400 is in Step 1070. Then, the flag area of the random number abnormality occurrence related information temporary storage unit 1440 is accessed to turn off the abnormality handling flag. Thereafter, the process proceeds to step 1902 in FIG. The same applies to the case of No in step 1069, that is, when the game is not currently being executed. When the power is turned on, if the first abnormality signal or the second abnormality signal is continuously output from the random number generator 750, either or both of the abnormality confirmation flags are turned on, and again The processing from step 1904 to step 1918 is executed. In this way, if the abnormality is not resolved even when the power is turned on, the game continues to be stopped.

  Next, FIG. 11 is a flowchart of the normal symbol winning random number acquisition process according to the subroutine of step 1100 in FIG. First, in step 1102, the usual game start entrance ball entry judging means 1113 judges whether or not a game ball has entered (inflow, passed) a universal game prize entry port (not shown). In the case of Yes in step 1102, in step 1104, the common random number acquisition determination execution means 1122 refers to the common figure hold information temporary storage means 1132a, and determines whether or not the number of held balls is not the upper limit (for example, four). In the case of Yes in step 1104, in step 1106, the normal random number acquisition determination execution means 1122 acquires the normal symbol winning random number. Next, in step 1108, the general-purpose holding means 1132 adds 1 to the holding ball in the form of setting the random number in the general-purpose holding information temporary storage means 1132a together with information on what number of the holding is made. The process proceeds to (Electric Chu Drive Determination Process 1200). In the case of No in step 1102 and step 1104, the process proceeds to the next process (electric drive drive determination process 1200).

  Next, FIG. 12 is a flowchart of the electric drive driving determination process according to the subroutine of step 1200 in FIG. First, in step 1202, the electric chew opening / closing control means 1160 refers to the auxiliary game related information temporary storage means 1192a to determine whether or not the electric chewing-opening flag is off. In the case of Yes in step 1202, in step 1204, the normal chart control means 1152 refers to the auxiliary game related information temporary storage means 1192a to determine whether or not the normal symbol changing flag is off. In the case of Yes in step 1204, in step 1206, the general figure content determining means 1142 accesses the general figure holding information temporary storage means 1132a and determines whether or not there is a holding ball related to the normal symbol. In the case of Yes in step 1206, in step 1210, the general contents determination unit 1142 refers to the temporary flag storage unit 1191a to determine whether or not the current gaming state is in the easy release state (time reduction flag on). In the case of Yes in step 1210, in FIG. 1212, in the step 1212, the general drawing content determination means 1142 sets the drawing time reduction lottery table 1142a-2, whereas in the case of No in step 1210, in the step 1214, The general map content determination means 1142 sets the normal map lottery table 1142a-1. In step 1216, the general symbol content determining means 1142 determines a stop symbol based on the normal symbol random number based on the reserved ball. Next, in step 1218, the usual figure fluctuation time management means 1152a sets the usual figure fluctuation management timer 1152a-1 based on the set table for a predetermined time (for example, 5 seconds in the case of a short-time game, in the case of a normal game). Is set to 30 seconds). Then, in step 1220, the general symbol control means 1152 turns on the normal symbol changing flag in the auxiliary game related information temporary storage means 1192a. Next, in step 1222, the general figure holding means 1132 updates the holding information recorded in the general figure holding information temporary storage means 1132 a after subtracting 1 from the holding ball related to the normal symbol, and the normal figure control means. 1152 starts normal symbol fluctuation management timer 1152a-1, and then starts normal symbol fluctuation display on a common figure display section (not shown). Next, in step 1224, the normal time fluctuation time management means 1152a refers to the normal time fluctuation management timer 1152a-1 and determines whether or not the predetermined time has been reached. In the case of Yes in step 1224, in step 1226, the universal symbol control means 1152 confirms and displays the stop symbol determined by the universal symbol content determination means 1142 in the above step 1216 on the universal symbol display unit (not shown). Then, in step 1228, the normal figure control means 1152 turns off the normal symbol changing flag in the auxiliary game related information temporary storage means 1192a. Next, in step 1230, the condition determination means 1161 determines whether or not the stop symbol is “winning”. In the case of Yes in Step 1230, in Step 1232, the electric chew opening / closing control means 1160 sets the open timer 1162 for a predetermined time (for example, 5 seconds for short-time game, 0 for normal game) based on the set table. .5 seconds) set. Next, in step 1234, the electric chew opening / closing control means 1160 turns on the electric chew-opening flag in the auxiliary game related information temporary storage means 1192a. In step 1236, the electric chew opening / closing control means 1160 opens the electric accessory of the first start winning opening (first special figure start opening) 24a. Next, in step 1238, the electric chew opening / closing control means 1160 refers to the opening timer 1162, and determines whether or not the predetermined time has been reached. In the case of Yes in Step 1238, in Steps 1240 and 1242, the electric chew opening / closing control means 1160 closes the electric combination of the first start winning opening (first special figure start opening) 24a and temporarily turns the auxiliary game related information temporarily. The electric-chu-opening flag in the storage means 1192a is turned off, and the processing proceeds to the next processing (special game content determination random number acquisition processing in step 1300).

  If NO in step 1202, the process proceeds to step 1238. If NO in step 1204, the process proceeds to step 1224. If NO in step 1206, step 1224, step 1230, and step 1238, the next process is performed. The process proceeds to (Special Game Content Determination Random Number Acquisition Process in Step 1300).

  Next, FIG. 13 is a flowchart related to the special game content determination random number acquisition process according to the subroutine of step 1300 in FIG. First, in Step 1302, the first start entrance entering ball judging means 1111 or the second start entrance entrance judging means 1112 is the first start winning sensor 51 or the first start entrance sensor (first special figure starting port) 24a. It is determined whether or not the special drawing start opening entry information is received from the second start winning sensor 52 of the 2 start winning opening (second special drawing start opening) 24b. In the case of Yes in step 1302, in step 1304, the special figure random number acquisition determination execution means 1121 refers to the special figure reservation information temporary storage means 1131a, and determines whether or not the number of reserved balls is not the upper limit (for example, four). In the case of Yes in step 1304, in step 1306, the special figure random number acquisition determination execution means 1121 acquires a game content determination random number (winning random number, variation mode determination random number, special symbol determination random number, etc.), and the special figure reservation means 1131 Then, the random number is set in the special figure holding information temporary storage means 1131a together with information on how many pieces are on hold, and the process proceeds to the next process (special symbol display process in step 1400). In addition, also when it is No in step 1302 and step 1304, it transfers to the following process (special symbol display process of step 1400).

  Next, FIG. 14 is a flowchart of special symbol display processing according to the subroutine of step 1400 in FIG. First, in step 1402, the special figure content determination unit 1141 determines whether or not a change start condition (not in special game + not in special symbol change) is satisfied.

  In the case of Yes in step 1402, in step 1414, the success / failure lottery means 1135 reads the game content determination random number related to the current symbol variation, which is temporarily stored in the special figure hold information temporary storage means 1131a. Next, at step 1403, the winning / not-to-use lottery means 1135 refers to the winning / losing lottery table of the special figure content determining lottery table 1141a, and executes the special symbol winning / raising lottery based on the game content determining random number (winning random number). In step 1417, the lottery means 1135 determines whether or not the lottery result is a hit. In the case of Yes in step 1417, in step 1418, the special game transition determining unit 1135a turns on the “win flag” in the temporary flag storage unit 1191a, and proceeds to step 1404. On the other hand, if step 1417 is No, step 1418 is skipped.

  Next, in step 1404, the special figure content determination unit 1141 refers to the flag temporary storage unit 1191a to determine whether or not the probability variation flag is on. In the case of Yes in step 1404, in step 1406, the special figure content determination means 1141 sets the special figure probability variation gaming state lottery table 1141a-2 as a reference table based on the lottery result, and proceeds to step 1416.

  On the other hand, in the case of No in step 1404, in step 1408, the special figure content determination unit 1141 refers to the flag temporary storage unit 1191a and determines whether or not the time reduction flag is on. In the case of Yes in step 1408, in step 1410, the special figure content determination means 1141 sets the special figure time-saving gaming state lottery table 1141a-3 as a reference table based on the lottery result, and proceeds to step 1416.

  On the other hand, in the case of No in step 1408, in step 1412, the special figure content determination means 1141 sets the special figure normal gaming state lottery table 1141a-1 as a reference table based on the lottery result, and proceeds to step 1416. .

  In step 1416, the special figure content determination means 1141 refers to each lottery table set based on the lottery result, and determines a stop symbol related to the special symbol based on the game content determination random number (for example, the special symbol determination random number). In addition to the determination, the variation mode of the special symbol is determined based on the game content determination random number (for example, the variation mode determination random number), and these are temporarily stored in the special diagram information temporary storage unit 1191b. Next, in step 1420, the special figure fluctuation time management means 1151a sets a predetermined time (fluctuation time related to the fluctuation mode determined in step 1416) in the special figure fluctuation management timer 1151a-1. In step 1422, the special symbol control means 1151 starts the special symbol variation display on the special symbol display unit 2131 of the special symbol display device 2130 according to the variation mode stored in the special symbol information temporary storage unit 1191b. . Next, in step 1446, the special figure control unit 1151 turns on the changing flag in the temporary flag storage unit 1191a. In step 1434, the special figure fluctuation time management unit 1151a determines whether or not the predetermined time has been reached. Here, in the case of No in step 1434, the process proceeds to the next process (special game operation condition determination process in step 1500). On the other hand, in the case of Yes in step 1434, in step 1438, the special symbol control means 1151 stops the special symbol variable display on the special symbol display unit 2131 of the special symbol display device 2130, and the special symbol information temporary storage means 1191b. Display control is performed with the stop symbol stored in the table as a fixed stop symbol. Next, in step 1440, the special figure control means 1151 turns off the changing flag in the temporary flag storage means 1191a. In step 1442, the special figure fluctuation time management unit 1151 a resets the special figure fluctuation management timer 1151 a-1. Next, at step 1450, main controller 1000 executes a specific game end determination process described later. In step 1900, the main control unit 740 of the main board 700 executes an abnormality handling process to be described later, and proceeds to the next process (special game operation condition determination process in step 1500).

  In the case of No in step 1402, in step 1444, the special figure control unit 1151 refers to the flag temporary storage unit 1191a to determine whether or not the changing flag is on. If Yes in step 1444, the process proceeds to step 1434. If No, the process proceeds to the next process (special game operation condition determination process in step 1500).

  Next, FIG. 15 is a flowchart of the abnormality handling process according to the subroutine of step 1900 in FIG. First, in step 1902, the abnormality handling necessity determination unit 1420 refers to the flag area of the random number abnormality occurrence related information temporary storage unit 1440, and the first abnormality confirmation flag (see step 1054) and the second abnormality confirmation flag (step 1058). Whether or not any of them is off, that is, whether or not an abnormality has occurred in the random number generation unit 750 is determined. If YES in step 1902, the process proceeds to the next process (special game operation condition determination process in step 1500). On the other hand, in the case of No in step 1902, in step 1904, the abnormality handling necessity determination unit 1420 refers to the flag area of the random number abnormality occurrence related information temporary storage unit 1440 and checks whether the first abnormality confirmation flag is on. Determine whether or not. In the case of Yes in step 1904, in step 1906, the abnormality handling necessity determination unit 1420 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440 and turns off the first abnormality confirmation flag. In step 1908, the error notification unit 1433 performs first abnormality error notification that the first error display unit 61 a has received the first abnormality signal, and the process proceeds to step 1910. Note that if the answer is No in Step 1904, the process proceeds to Step 1910. In step 1910, the abnormality handling necessity determination unit 1420 refers to the flag area of the random number abnormality occurrence related information temporary storage unit 1440 and determines whether the second abnormality confirmation flag is on. In the case of Yes in step 1910, in step 1912, the abnormality handling necessity determination unit 1420 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440 and turns off the second abnormality confirmation flag. In step 1914, the error notification unit 1433 performs second abnormality error notification indicating that the second error display unit 61b has received the second abnormality signal, and the process proceeds to step 1916. Note that if the answer is No in Step 1910, the process proceeds to Step 1916. Next, in step 1916, the game progress stopping means 1431 accesses the flag area of the random number abnormality occurrence related information temporary storage means 1440 and turns on the abnormality handling flag. Thereafter, in a situation where this flag is on, the game does not proceed unless the abnormality of the random number generator 750 is resolved (see the case of No in step 1068 in FIG. 10). In step 1918, the game ball launch prohibiting unit 1432 transmits a command for forcibly stopping the launch regardless of the operation of the operation handle 8 to the launcher control board 200. On the side of the launching device control board 200 that has received this command, launching is forcibly stopped even when the operation handle 8 is being operated by the player. Thereafter, this step 1918 is continuously looped until the power is cut off. As described above, in this best mode, the error monitoring of the random number generator 750 is always executed, but the error handling process (error notification, game progress stop, launch forced stop) is configured to be executed after the symbol fluctuation stop. Yes.

  Next, FIG. 16 is a flowchart of specific game end determination processing according to the subroutine of step 1450 in FIG. First, in step 1452, the specific game control means 1180 refers to the time / count counter 1181a to determine whether or not the time / count counter value is greater than zero. In the case of Yes in step 1452, in step 1454, the specific game control means 1180 subtracts 1 from the time-count counter value of the time-count counter 1181a. Next, in step 1456, the specific game control means 1180 refers to the time reduction counter 1181a and determines whether or not the time reduction is zero. In the case of Yes in step 1456, in step 1460, the specific game control means 1180 turns off the time reduction flag in the flag temporary storage means 1191a, and proceeds to the next process (special game operation condition determination process 1500).

In the case of Yes in step 1504, in step 1506 and step 1508, the condition determination means 1171 turns on the special game transition permission flag in the flag temporary storage means 1191a and turns off the winning flag. Next, in steps 1552 and 1554, the specific game control unit 1180 temporarily turns off the specific game flag (probability variation flag / time reduction flag) in the flag temporary storage unit 1191a, and resets the time reduction counter 1181a (time reduction). The number counter value = 0), and the process proceeds to the next process (special game execution process in step 1600). It should be noted that, also in the case of No in step 1502 and step 1504, the process proceeds to the next process (special game execution process in step 1600).

  Next, FIG. 18 is a flowchart of special game execution processing according to the subroutine of step 1600 in FIG. First, in step 1602, the special game executing means 1172 refers to the flag temporary storage means 1191a and determines whether or not the special game transition permission flag is on. In the case of Yes in step 1602, in step 1606 and step 1608, the special game execution means 1172 turns off the special game transition permission flag in the flag temporary storage means 1191a and turns on the special game execution flag. On the other hand, in the case of No in step 1602, in step 1610, the special game execution means 1172 determines whether or not the special game execution flag is on. If YES in step 1610, the process proceeds to step 1612. In the case of No in step 1610, the special game executing means 1172 determines that the special game is not permitted, and proceeds to the next process (prize ball payout process 1800).

  Next, in step 1612, the special game execution means 1172 refers to the flag temporary storage means 1191a and determines whether or not the round continuation flag is on, in other words, whether or not the round is in the middle. . If Yes in step 1612, that is, if the round is in the middle, the process proceeds to step 1624 without performing the processes of steps 1614 to 1622 described in detail below. On the other hand, in the case of No in step 1612, that is, immediately before the start of the round, first, in step 1614, the special game executing means 1172 clears the special game timer 1173a to zero and sets a predetermined value (for example, per normal) 30 seconds for the special game based on the game, and 0.8 seconds for the special game based on the sudden probability fluctuation or the sudden time reduction. Next, in step 1616, the special game execution means 1172 clears the winning ball counter in the special game related information temporary storage means 1191c to zero. In step 1618, the special game executing means 1172 adds 1 to the round number counter in the special game related information temporary storage means 1191c. Note that the number of rounds stored in the special game related information temporary storage means 1191c is 0 immediately after the start of the special game (initial value), and is incremented by 1 each time the rounds are repeated thereafter. Next, in step 1620, the special game executing means 1172 turns on the round continuation flag in the flag temporary storage means 1191a. In step 1622, the special game executing means 1172 drives the electric accessory of the attacker 26 to release the attacker 26, and the process proceeds to step 1624.

  Next, in step 1624, the special game execution means 1172 refers to the special game related information temporary storage means 1191c and determines whether or not there are predetermined balls (for example, 10 balls) in the round. If Yes in step 1624, the process proceeds to step 1628. On the other hand, in the case of No in step 1624, in step 1626, the special game executing means 1172 refers to the special game timer 1173a and determines whether or not a predetermined time has elapsed. Also in the case of Yes in step 1626, the process proceeds to step 1628, and in the case of No, the process proceeds to the next process (prize ball payout process 1800).

  Next, in step 1628, the special game executing means 1172 stops driving the electric actor of the attacker 26 and closes the attacker 26. In step 1630, the special game executing means 1172 resets the special game timer 1173a. Next, in step 1632, the special game executing means 1172 turns off the round continuation flag in the flag temporary storage means 1191a. Next, in step 1634, the special game executing means 1172 refers to the special game related information temporary storage means 1191c, and the round is the last round (for example, 15R if the special game is based on the normal hit, If it is a special game based on the sudden time reduction, it is determined whether or not it is 2R). In the case of Yes in step 1634, in step 1636, the special game execution means 1172 turns off the special game execution flag in the flag temporary storage means 1191a. In step 1650, the game control unit 1100 executes a game state determination process after the end of the special game, which will be described later, and proceeds to the next process (prize ball payout process 1800). In the case of No in step 1634, the process proceeds to the next process (prize ball payout process 1800).

  Next, FIG. 19 is a flowchart of the game state determination process after the end of the special game according to the subroutine of step 1650 in FIG. First, in step 1656, the specific game control means 1180 refers to whether or not the probability change per unit, that is, the special symbol stopped on the special figure display unit 2131 with reference to the special figure information temporary storage means 1191b. It is determined whether or not there is. In the case of Yes in step 1656, in step 1658 and step 1660, the specific game control means 1180 turns on the probability variation flag and the time reduction flag in the flag temporary storage means 1191a, respectively, and the next process (prize ball payout process 1800). ).

  On the other hand, in the case of No in step 1656, in step 1662, the specific game control means 1180 stops on the special figure display unit 2131 with reference to whether or not it is per time reduction fluctuation, that is, the special figure information temporary storage means 1191b. It is determined whether or not the special symbol is per time reduction variation. In the case of Yes in step 1662, in step 1664, the specific game control means 1180 turns on the time reduction flag in the flag temporary storage means 1191a. Next, in step 1666, the specific game control means 1180 sets a predetermined value (for example, 100) as the time / count counter value in the time / count counter 1181a, and proceeds to the next process (prize ball payout process 1800). Even in the case of No in step 1662, the process proceeds to the next process (prize ball payout process 1800).

  Next, the operation of the pachinko gaming machine according to the best mode will be described. Hereinafter, what internal processing is executed at each timing when an abnormality has occurred will be described in order.

(If an abnormality occurs when not playing)
In the pachinko gaming machine according to the best mode, as can be seen from the main flowchart of FIG. 9, the abnormality monitoring process itself is always executed. Therefore, if an abnormality occurs while not playing a game, the occurrence of the abnormality is immediately recognized (the abnormality confirmation flag is turned on in step 1054 or step 1058 in FIG. 10). Here, in the case of the title, since the game is not being executed, it is possible to immediately take an abnormality countermeasure. Therefore, in this case, an abnormality handling measure (error notification, forced firing stop, game progress stop) is immediately executed (see the case of No in step 1069 in FIG. 10).

(If an abnormality occurs during symbol fluctuation)
Also in this case, the occurrence of an abnormality is immediately recognized (the abnormality confirmation flag is turned on in step 1054 or step 1058 in FIG. 10). However, if the game is forcibly stopped while the symbols are changing, the player may be confused. Therefore, immediately after the symbol variation is completed, an abnormality handling measure (error notification, forced launch stop, game progress stop) is executed (after step 1440 in FIG. 10). In addition, in the situation where abnormality countermeasures are taken, the progress of the game is stopped, so if this symbol is a losing symbol, it does not shift to the next symbol variation, and this symbol is a winning symbol If it is, it does not shift to special games.

(If an abnormality occurs during a special game)
Also in this case, the occurrence of an abnormality is immediately recognized (the abnormality confirmation flag is turned on in step 1054 or step 1058 in FIG. 10). However, if the launch is forcibly stopped during a special game, the player's profit will be seriously damaged. Therefore, immediately after the special game is finished, immediately before the symbol variation is started, the abnormality countermeasure (error notification, forced launch stop, stop game progress) is executed (see the case of No in step 1069 in FIG. 10). .

  According to the best mode, when an abnormality occurs in the random number clock generation circuit and the clock count circuit, the timing at which the variation display of the identification information is terminated and the stop display is executed in a situation where the identification information is being varied. Therefore, it is configured to execute the abnormality response necessity determination process and the abnormality response process (game progress stop process and game ball launch prohibition process). In addition to being able to reduce complexity and capacity, the anomaly handling process is configured to forcibly stop firing after the progress of the game is stopped, so it can fire during regular jackpots. A new random number is acquired by giving a disadvantage to the player (disadvantage of not stopping the game progress) or by continuing the launch It also bring out the effects that it becomes possible to avoid (disadvantage of not forcibly stop the firing).

  Furthermore, since it is configured to execute the abnormality response necessity determination process even in a situation where the game (identification information variation game and special game) is not being executed, abnormality detection and countermeasures should be taken before the game is executed. There is an effect that becomes possible.

  Next, a modified example of the best mode will be described. In this best mode, the random number monitoring is always executed. However, the present invention is not limited to this, and the random number monitoring may be executed only at the timing when the abnormality countermeasure is taken. In this case, for example, a mode in which the random number monitoring process 1050 in FIG. 9 is executed immediately before the abnormality handling process 1900 in FIG.

  According to this modified example, not only abnormality response necessity determination processing and abnormality response processing (game progress stop processing and game ball launch prohibition processing) but also abnormal signal monitoring processing itself is stopped after the variation display of the identification information ends. Since it is configured to be executed at the timing when the display is executed, the internal processing is not complicated and can be reduced in capacity as compared with the case where these processes are always executed. There is an effect.

  Furthermore, in this best mode, the overflow signal is monitored and the high signal from the IC 14 is detected to detect the abnormality of the random number clock generating means and the random number counting means. However, the present invention is not limited to this, and the first count value You may employ | adopt the method of determining these abnormalities by determining the random number value memorize | stored in a memory circuit or a 2nd count value memory circuit. Hereinafter, this modified example will be described with reference to FIGS. 3 and 20.

First, FIG. 3 is a functional block diagram of this modified example. Here, the most part is the same as the best mode, and the portion indicated by the dotted line is the changed point. The change will be described below. The random-number abnormality occurrence control unit 1400 includes an abnormality determination control unit 1450 that controls the abnormality determination. Here, the abnormality determination control unit 1450 includes an abnormality determination random number acquisition control unit 1451 that acquires a random number generated by the random number generation unit as an “abnormality determination random number”, and an abnormality that determines whether it is an abnormality determination processing timing. It has a determination execution possibility determination unit 1452 and an abnormality determination execution unit 1453 that executes abnormality determination. Further, the abnormality determination random number acquisition control means 1451 has abnormality determination random number temporary storage means 1451a for temporarily storing abnormality determination random numbers. As will be described later, since abnormality determination is executed based on whether or not the random number values are the same, a plurality of abnormality determination random numbers need to be temporarily stored for comparison. Therefore, the abnormality determination random number temporary storage unit 1451a according to this modification is configured to be capable of temporarily storing a plurality of abnormality determination random numbers as shown in Table 1 below. However, it is not necessary to physically store a plurality of abnormality determination random numbers in one temporary storage means. For example, an area (for example, a first register) for temporarily storing previously acquired random numbers and a new acquisition this time A place (for example, the second register) for temporarily storing the random number may be provided separately. Further, the abnormality determination execution unit 1453 includes an abnormality occurrence number temporary storage unit (check counter) 1453a for temporarily storing the number of abnormality occurrences.

  Next, FIG. 20 is a flowchart of random number circuit unit abnormality occurrence determination processing. Here, FIG. 20 is basically a process that may be executed at any timing (for example, executed before step 1050 of the main flow according to the best mode). The processing will be described. First, in step 11002, the abnormality determination random number acquisition control unit 1451 determines whether or not it is the abnormality determination random number acquisition timing. Here, the “abnormality determining random number” is a random number for determining whether or not an abnormality has occurred in the random number circuit. In this example, it is data obtained by copying a random number temporarily stored in the first count value storage circuit B91 or the second count value storage circuit B92. Also, the “abnormality determination random number acquisition timing” is not particularly limited. For example, a new random number is acquired for a game purpose such as a lottery (for example, a game ball enters a start opening and a random number is acquired. (Acquired timing) or any timing (for example, immediately after power-on). In addition, when the “abnormality determination random number” is acquired at the timing when a random number for game purposes (game content determination random number) is newly acquired, this “game content determination random number” is set to “anomaly determination random number”. It is preferable to copy as. On the other hand, when the “abnormality determination random number” is acquired at an arbitrary timing, the random number is acquired only for abnormality determination. In the case of Yes in step 11002, in step 11004, the abnormality determination random number acquisition control unit 1451 temporarily stores the acquired abnormality determination random number in the abnormality determination random number temporary storage unit 1450a. Here, the abnormality determination random number temporary storage unit 1451a in the present modification is acquired not only in the abnormality determination random number acquired this time but also in the past (for example, only once or once to several times before) as described above. The abnormality determination random number is also temporarily stored. The following explanation is based on the assumption that the abnormality determination random number temporary storage means 11004 can temporarily store four abnormality determination random numbers (see Table 1). If NO in step 11002, the process proceeds to step 11006.

  Next, in step 11006, the abnormality determination execution possibility determination unit 1452 determines whether it is the timing of the abnormality determination process. Here, the “abnormality determination processing timing” is not particularly limited, but may be, for example, when a new random number for determining game contents is acquired as described above, or after power-on. However, in any case, it should be noted that the abnormality of the random number generation unit cannot be determined unless there are at least two random numbers to be compared in the abnormality determination random number temporary storage unit 1450a. Therefore, the abnormality determination processing timing needs to be a situation in which at least two random numbers to be compared exist in at least the abnormality determination random number temporary storage unit 1450a. Therefore, for example, at the time of power failure recovery such as when the power is turned on, since a plurality of random numbers are not stored in the abnormality determination random number temporary storage unit 1450a, the abnormality determination random number is acquired by executing latching at least twice. It is necessary to keep. Returning to the description of the processing, in step 11008, the abnormality determination execution unit 1453 has a plurality of abnormality determination random numbers temporarily stored in the abnormality determination random number temporary storage unit 1451a (for example, the first stored random number value and The second stored random number value is compared. In step 11010, the abnormality determination execution unit 1453 determines whether or not both random numbers have the same value as a result of the comparison in step 11008. If Yes in step 11010, the abnormality determination execution unit 1453 increments the check counter 1453a by one. On the other hand, in the case of No in step 11010, in step 11013, the abnormality determination execution unit 1453 clears the check counter 1453a.

  Next, in step 11014, the abnormality determination execution possibility determination unit 1452 determines whether or not to end the comparison processing in step 11008. If NO in step 11014, that is, if the comparison process is still continued, the process proceeds to step 11008. For example, when only one comparison process is executed per abnormality determination timing, this process is unnecessary. On the other hand, this processing is necessary when performing comparison processing a plurality of times per abnormality determination timing. For example, when an abnormality occurrence determination process is to be executed collectively when there are a plurality of holds, the held random number values are collectively copied to the abnormality determination random number temporary storage unit 1451a at a predetermined timing. A comparison between the first random number on hold and the second random number, a comparison between the second random number on the hold and the third random number, and a comparison between the third random number on the hold and the fourth random number. The comparison process is executed three times (three times in this example).

  Next, in step 11016, the abnormality determination control unit 1450 determines whether or not the abnormality condition is satisfied, specifically, whether or not the abnormality frequency value in the check counter 1453a has reached a predetermined value (for example, three times). Determine whether. In the case of Yes in step 11016, in step 11018, the abnormality determination control unit 1450 accesses the flag area of the random number abnormality occurrence related information temporary storage unit 1440, turns on the abnormality confirmation flag, and ends the processing. Note that the process is also terminated in the case of No in step 11016. The abnormal frequency value may be varied depending on the situation. For example, the abnormal frequency value is three times in normal times, but may be four times when the power is turned on. In this modified example, it is determined that there is an abnormality continuously for a predetermined number of times. However, the check counter clear process in step 11013 when the abnormality is not confirmed is eliminated, and an abnormality is determined when the predetermined number of times is reached. It may be configured. Alternatively, in the case where it is configured to determine “abnormal” when the number of abnormalities occurring per unit time reaches a predetermined number, a check counter after a predetermined time (which may be only the time during which the game is executed) has elapsed. To clear.

  Note that this modification example is based on the premise that the modification is executed on the main board 700, but the present invention is not limited to this. In this case, a random number acquired by the main board 700 is transmitted to the sub side. Further, it may be configured to perform abnormality handling (for example, error processing) on the sub-board side.

  Furthermore, a double check that combines the abnormality determination in this best mode and the abnormality determination in this modification may be executed. Further, the time when this double check is performed may be limited only to a predetermined timing or a period (for example, when it is a big hit).

  Furthermore, in this best mode and this modified example, for example, when an abnormality occurs in the random number generation circuit, a period during which the game is continued from the abnormality occurrence timing to the timing when the abnormality countermeasure is taken (that is, the game ball is fired). Possible period) exists. During this period, if a launched game ball enters the start port, a new random number is put on hold. In this case, for example, when an abnormality occurs in the random number generation circuit and only the winning random number value is acquired, the random numbers newly acquired in this period are only the winning random numbers. For example, in a model that can hold eight, a maximum of eight random numbers may be acquired. It is not preferable to leave such a situation because it causes serious damage to the hall. Therefore, for example, it is preferable to execute the following processing. First, as in the present modification example, it is determined whether or not a plurality of random numbers acquired at different timings (for example, the current determination random number for determination and the previous determination random determination random number) have the same value. At this time, if it is determined that they are the same value, the presence or absence of an abnormal signal (in this example, an overflow signal or the like) is determined from the random number generator as in the best mode. When the same value is continuously acquired as a random number value and an abnormal signal is detected from the random number generation unit, the random number acquired later is a random number acquired as a result of the occurrence of an abnormality in the random number generation unit. There is a high probability. Therefore, in this case, the process of deleting the random number related to the same value that is suspended is executed (if there are a plurality of consecutive random numbers having the same value, it is preferable to delete all of them. is there). Thereby, it becomes possible to stop in advance the damage on the hall side resulting from the occurrence of an abnormality in the random number generator. Note that the timing at which such processing is executed is not particularly limited. For example, when a new random number is acquired at the start port, the random number may be compared with the immediately preceding random number value. When the change related to the hit random number is started, it is possible to compare whether the hold existing at the time of the change is the same value as the hit random number.
