Abstract

<P>PROBLEM TO BE SOLVED: To prevent fraudulent play due to a fraudulent means such as a pulsator. <P>SOLUTION: The controller of a game machine includes a step (S22) of changing a first count value from a start value to an end value taking a plurality of interval periods by adding the first count value of a first counter once in every interval (S12), and a step (S24) of changing the start value and end value of the first count value in the next interval when the first count value reaches the end value. By changing both of the start value and the end value, it is made difficult to match the timing of entering and passing with the timing of a winning. Thus, the fraudulent game is prevented. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a control device for a gaming machine and relates to a technique for preventing unauthorized gaming.

  In a gaming machine such as a pachinko machine or a slot machine machine, whether it is “winning” or “out of” is determined by a random value. The value of the random number matches the value of the counter (that is, the count value), and is changed within a predetermined range every interval (for example, 4 milliseconds). That is, normally, the counter value is incremented by 1, and when the counter value reaches the end value, the counter is initialized to the start value and circulated. For example, assuming that the predetermined range is 0 to 299, the start value is 0 and the end value is 299. In this example, it is incremented by 1 when the counter value is 0 to 298, and is initialized to 0 when the counter value is 299. Therefore, the counter continues to be updated periodically from when the gaming machine is powered on (or reset).

  The count value is often used for symbol display of a symbol display provided in a gaming machine. That is, when a game ball wins at the starting port where the symbol variation starts, the count value when the winning is detected is read. Then, according to the read count value (hereinafter referred to as “read value”), the content of the symbol displayed on the symbol display device is controlled. For example, it is assumed that only “7” is a winning in the predetermined range. If the read value is “7”, control is performed so that the content of the symbol displayed on the symbol display is stopped in a “winning” manner (specifically, a winning symbol such as “777”). Further, if the read value is a value other than “7”, the content of the symbol displayed on the symbol display device is controlled to stop in a “displacement” mode according to the value.

  Here, in the pachinko machine, the timing at which the game ball wins the start opening (hereinafter referred to as “winning timing”) is not uniform because the game ball behaves randomly due to many obstacle nails arranged on the game board surface. Therefore, even if the count value of the counter updated every interval is read at the winning timing, the read value eventually becomes a random value. However, since the counter is updated at intervals, the period from when a “win” comes out until the next “win” comes out is also constant. The period is equal to a period during which the count value makes a round of the predetermined range, and is hereinafter referred to as a “count period”. In the example of the predetermined range, when 300 values are updated every 4 milliseconds, the count cycle becomes 1.2 seconds. Therefore, if the game ball wins the starting opening 1.2 seconds after the reading value once becomes a winning value, the reading value at that time also becomes a winning value.

  By the way, there is a so-called “sensory sensation device” that generates signals such as vibrations and sounds at regular intervals. If the player turns on / off the launching device according to the signal generated by the sensor, the game ball can be fired at regular intervals. Moreover, depending on the operation pattern of a member, a player may know the said fixed period irrespective of a body sensor. As an operation pattern of this member, there are, for example, a blinking pattern of a lamp provided on the game board surface, a sound effect emitted from a speaker, an operation pattern of an accessory, and the like. Further, the operation pattern of the members is generally operated at a timing unrelated to one cycle of the counter. However, if the counter operates in synchronization with one cycle of the counter due to a design or manufacturing error, the player can know the fixed cycle. If the player turns on / off the launching device according to the operation pattern of this member, the game ball can be fired at regular intervals. However, as described above, since a number of obstacle nails are provided on the game board surface, the winning timing does not necessarily occur periodically.

  However, if the game ball is fired at every cycle of the counter (1.2 seconds in the above example), the winning timing can be generated periodically. Therefore, it is possible to increase the probability of “winning” when winning at the start opening. Therefore, it is possible to generate “hit” almost certainly if a game is played with a sensory device or the like. Such illegal games are intentionally aimed at “winning”, and are unfair and should not be allowed in consideration of general players who play for “winning” due to chance. The present invention has been made in view of these points, and an object of the present invention is to provide a control device for a gaming machine that prevents unauthorized gaming by unauthorized means such as a sensory device.

A control device for a gaming machine according to claim 1 is:
A control device for a gaming machine having a game control program for executing a game process at every interval,
The game control program is
Changing the first count value from the start value to the end value over a plurality of interval periods by adding the first count value of the first counter once every interval;
When the first count value reaches an end value, changing a start value and an end value of the first count value in a next interval;
Switching a gaming state of the gaming machine based on a first count value at that time when a predetermined gaming condition is established,
The control device includes a second counter for determining the start value and the end value of the first counter,
The addition value for adding the second count value once and the addition value for adding the first count value once are the same value,
The cycle of adding the second count value once is shorter than the cycle of adding the first count value once,
The control device adds the first count value once in the one interval, and then adds the second count value of the second counter once until the one interval elapses. Repeatedly
When the start value and the end value of the first count value are changed, the start value of the first count value after the change is the same value as the start value of the first count value before the change There is,
It is characterized by that.

[Embodiment 1]
First, Embodiment 1 in which the change from when the count value reaches the end value to various values will be described with reference to FIGS. Here, FIG. 1 shows a front view of the appearance of the pachinko machine. FIG. 2 is a block diagram showing the configuration of the first control unit. 3 shows the first main process, FIG. 4 shows the first count process (count process Pa), FIG. 5 shows the second count process (count process Pb), and FIG. 6 shows the jackpot discrimination process. FIG. 7 is a flowchart showing the third count process (count process Pc). FIG. 8 is a time chart showing changes with time of the count value. In these drawings, common elements are denoted by the same reference numerals.

  In FIG. 1, on the game board surface 12 of the pachinko machine 10, a composite device 14, a first type starting port 18, a grand prize winning port 20, and the like are provided as appropriate. The composite device 14 is provided with a gate sensor 38, a normal symbol display 40, a special symbol display 42, and the like. The first type starting port 18 is one of specific areas described later, and acts in the same way as a normal winning port to pay out a prize ball (also called a prize ball). The gate only detects the passage of the pachinko ball (game ball) by the gate sensor 38, and the prize ball is not paid out. The normal symbol display 40 displays normal symbols (for example, alphanumeric characters and symbols). This normal symbol starts to change when the pachinko ball passes the gate and then stops. The special symbol display 42 displays special symbols (for example, patterns, alphanumeric characters, symbols, etc.). The special symbol starts to change when the pachinko ball wins the first type starting port 18 and then stops.

  The first type starting port 18 is provided with a starting port sensor 34. When the start port sensor 34 detects a pachinko ball that has won the first type start port 18, the start port sensor 34 outputs a winning signal. The special winning opening 20 is provided with a lid 20 a, which is opened and closed by a solenoid 32. The special winning opening 20 is provided with a V zone 20b as a special area. If the pachinko ball wins the V zone 20b at a certain time, the big hit gaming state can be continued within a certain limit (for example, 16 times). Other than the game board surface 12, a lower plate 26 for temporarily storing pachinko balls including a prize ball, a speaker 28 for producing sound effects and music, and whether or not the player's hand is touching the handle 22 are detected. A touch sensor 24, a firing motor 21 for operating the handle 22 to launch a pachinko ball, and a metal frame sensor 36 for detecting the opening of the glass frame 17 are provided. The speaker 28 is provided inside an upper plate 30 that is a tray for receiving a prize ball, and the touch sensor 24 and the metal frame sensor 36 are respectively provided at predetermined positions. Moreover, LED, a light bulb, etc. are used for the lamps 16 and are arrange | positioned in a suitable position according to the game content of the pachinko machine 10, etc.

  Next, the main controller 100 will be described with reference to FIG. The main control unit 100 includes a CPU (processor) 110, a ROM 102, a RAM 104, an oscillator 101, an input processing circuit 108, an output processing circuit 112, a display control circuit 114, a communication control circuit 116, and the like. The oscillator 101 outputs a pulse signal at a substantially constant cycle and controls the operation of the CPU 110. The CPU 110 controls the pachinko machine 10 by executing a game control program recorded in the ROM 102. The game control program includes a program for realizing a jackpot determination process and the like which will be described later. The ROM 102 is an EPROM, but an EEPROM or a flash memory may be used. Various data or input / output signals are stored in the RAM 104. A DRAM is used for the RAM 104, but a nonvolatile memory such as an SRAM or a flash memory may be used. The counter 111 is provided in the CPU 110 (for example, a register or a buffer).

  The input processing circuit 108 receives a winning signal sent from the start port sensor 34 or the gate sensor 38, converts it into a data format that can be processed in the main control unit 100, and sends data to the CPU 110 or RAM 104 via the bus 118. Send. The output processing circuit 112 receives the operation data sent from the CPU 110 via the bus 118 and operates various operation devices provided in the pachinko machine 10 such as the lamps 16 and the solenoid 32. The display control circuit 114 receives display data sent from the CPU 110 via the bus 118 and performs control for displaying characters, symbols, images, etc. on the normal symbol display 40 and the special symbol display 42. . The communication control circuit 116 is a circuit for transmitting / receiving data to / from the frame control unit 200 (or the hall computer 300). The frame control unit 200 is configured around a CPU as in the case of the main control unit 100, and since the configuration is known, detailed description thereof is omitted. The frame control unit 200 controls the launch of the pachinko balls and the payout of the prize balls necessary for performing the pachinko game, and outputs sound effects and music from the speaker 28, or opens the door by the metal frame sensor 36. Inspection and the like are performed at a predetermined timing. Also, each of the above components is coupled to the bus 118.

  Next, the counting process performed in the main control unit 100 will be described with reference to FIGS. The counting process includes a case where the count value of the counter is counted up, a case where the count value is counted down, and a case where both are mixed. Here, in order to simplify the description, the case of counting up will be described. Therefore, the start value Cmin corresponds to the lower limit value, and the end value Cmax corresponds to the upper limit value.

  In the main process shown in FIG. 3, it is first determined whether or not a specific condition is satisfied [step S10]. Here, the “specific condition” is set in advance according to the type of pachinko machine, the date and time, and the like. Note that the specific condition may be changed in a timely manner according to the gaming state or the like. In addition, specific examples where the specific condition is satisfied include a case where a pachinko ball has won or passed a specific area (the first type starting port 18 or the like), or a big hit state. If the specific condition is satisfied (YES), the count process Pb is executed [step S14]. On the other hand, when the specific condition is not satisfied (NO), the count process Pa is executed [step S12].

  Here, the processing content of the count processing Pa will be described with reference to FIG. In the count process Pa, the count value C of the counter 111 provided in the CPU 110 shown in FIG. In FIG. 4, first, the count value C is incremented by 1 [step S30]. That is, C = C + 1 is calculated. As a result of this calculation, it is determined whether or not the count value C has reached the end value Cmax [step S34]. That is, the determination is made based on whether or not C ≧ Cmax is satisfied. If the count value C reaches the end value Cmax (YES), the count value C is initialized with the start value Cmin [step S36]. That is, C = Cmin is executed. At this time, the value to be initialized is not limited to the start value Cmin but may be any other value. On the other hand, when the count value C has not reached the end value Cmax (NO), the count process Pa is ended without doing anything. In this process, the start value Cmin corresponds to the lower limit value, and the end value Cmax corresponds to the upper limit value.

  Note that the change value X may be added to the count value C instead of or in addition to step S30 [step S32]. Specifically, the change value X is obtained by referring to the data table TB2 based on the count value N of the free counter 105 provided in the RAM 104 shown in FIG. 2, and the change value X is added to the count value C. That is, C = C + X is executed. The data table TB2 defines the correspondence between the count value N and the change value X, and the same applies to the data tables TB4 and TB6 shown below. In this case, the change value X may be any value, but when it is a prime number, it is more preferable in that the change of the count value C is diversified. By executing step S32, the count value C of the counter 111 can be changed greatly.

  The processing content of the counting process Pb will be described with reference to FIG. In the count process Pb, the count value C of the counter 111 provided in the CPU 110 shown in FIG. 2 is incremented by the count value N of the free counter 105 within a predetermined range. In FIG. 5, first, the count value C is added by the count value N [step S40]. That is, C = C + N is calculated. As a result of this calculation, it is determined whether or not the count value C has reached the end value Cmax [step S44]. That is, the determination is made based on whether or not C ≧ Cmax is satisfied. If the count value C reaches the end value Cmax (YES), the count value C is initialized with a value obtained by subtracting the end value Cmax from the count value C [step S46]. That is, C = C-Cmax is executed. On the other hand, when the count value C has not reached the end value Cmax (NO), the count process Pb is ended without doing anything.

  In place of or in addition to step S40, the change value X is obtained by referring to the data table TB4 based on the count value N of the free counter 105 as in step S32 shown in FIG. Then, the change value X may be added to the count value N [step S42]. That is, the calculation of C = C + X is executed. In step S46, the count value C may be initialized with the start value Cmin.

  Returning to FIG. 3, after the count value C is counted up, a game process for a pachinko game is performed [step S16]. In this game process, the fluctuation process of the normal symbol display 40 performed when the pachinko ball passes the gate sensor 38, the fluctuation process of the special symbol display 42 performed when the pachinko ball wins the first type starting port 18, Various processes for realizing a pachinko game are performed, such as a payout process of a prize ball performed when a ball wins. One of them is a jackpot determination process, which will be described with reference to FIG. In the jackpot determination processing, processing for determining jackpot / loss is performed.

  In FIG. 6, it is determined whether or not a pachinko ball has won the first type starting port 18 [step S50]. If the pachinko ball is won (YES), the counter 111 is referred to obtain the count value C [step S52] and the jackpot value stored in the RAM 104 (or ROM 102) is obtained [step S54]. . And it is discriminate | determined whether it is big hit [step S56]. Specifically, the determination is made based on whether or not the count value C acquired in steps S52 and S54 matches the jackpot value. If they match (YES), jackpot processing is performed [step S58]. As the jackpot processing, the jackpot symbol is displayed on the special symbol display 42 and the lid 20a of the big prize opening 20 is opened for a predetermined period and a predetermined number of times. In this way, the player can obtain many prize balls. On the other hand, when the pachinko ball is not won at the first type starting port 18 (NO in step S50) or when it is not a big hit (NO in step S56), the jackpot process is terminated without doing anything thereafter.

  Returning to FIG. 3 again, after the game process of step S16 is completed, the count process Pc is executed [step S18] from the start of execution of step S10 until the interval Δt (for example, 4 milliseconds) elapses [step S20]. ]. The count process Pc is a process for counting up the count value N of the free counter 105 and will be described with reference to FIG. In FIG. 7, first, the count value N is incremented by 1 [step S60]. That is, N = N + 1 is calculated. As a result of this calculation, it is determined whether or not the count value N has reached the end value Nmax [step S64]. That is, the determination is made based on whether or not N ≧ Nmax is satisfied. If the count value N reaches the end value Nmax (YES), the count value N is initialized with the start value Nmin [step S66]. That is, N = Nmin is executed. On the other hand, when the count value N has not reached the end value Nmax (NO), the count process Pc is ended without doing anything.

  In place of or in addition to step S60, the change value X is obtained by referring to the data table TB6 based on the count value N of the free counter 105 as in step S32 shown in FIG. Then, the change value X may be added to the count value N [step S62]. That is, the calculation of N = N + X is executed.

  Returning to FIG. 3 again, when the interval Δt has elapsed in step S20, the process returns to step S10 again. In this way, step S10 to step S20 are repeatedly executed. At this time, the count value C of the counter 111 circulates within the range from the start value Cmin to the end value Cmax and changes in an increasing direction. This will be described with reference to FIG. Here, in the time charts of FIG. 8, FIG. 9 (B), FIG. 10 (B), etc., the change pattern P0 indicated by the solid thin line is a pattern obtained by the counting process in the conventional pachinko machine. That is, it starts increasing from the start value Cmin at time t10, reaches the end value Cmax at time t16, and is initialized to the start value Cmin. Then, it starts increasing from the start value Cmin again at time t16. After that, it changes in the same manner. Therefore, the interval at which the count value C coincides with a specific jackpot value (hereinafter referred to as “hitspot interval” in this specification) is substantially equal to the period from time t10 to time t16. Note that the count value C actually changes stepwise at intervals Δt, as shown in the upper right circle of the drawing. Further, in each time chart, the change of the count value C is indicated by an oblique line segment so that the entire change pattern can be easily understood.

  When the main process shown in FIG. 3 is executed, the count value C becomes a change pattern P2 indicated by a bold solid line as shown in FIG. That is, when step S12 is executed, it increases from the start value Cmin at time t10 as in the conventional change pattern P0. Then, at time t12, the specific condition is satisfied and step S14 is executed, and the count value C is greatly increased. After that, since it changes again similarly to the conventional change pattern P0, it reaches the end value Cmax at time t14 and is initialized to the start value Cmin. Then, it again starts increasing from the start value Cmin at time t14, changes slightly due to the specific condition being satisfied at time t18, and reaches the end value Cmax at time t20. Thereafter, every time the specific condition is satisfied, the count value C changes.

  According to the first embodiment, the pulse value output from the oscillator 101 is received and the count value C of the counter 111 is changed from the start value Cmin to the end value Cmax. Further, the big hit interval in the change pattern P2 is approximately equal to the period from time t10 to time t14 in the first cycle, and is approximately equal to the period from time t14 to time t20 in the second cycle. The length of the period required for the change until the count value C reaches the end value Cmax from the start value Cmin (that is, the transition period) expands and contracts only once or a plurality of times. As a result, it is different from other periods at least once. Then, when the jackpot symbol is displayed on the special symbol display 42 (predetermined gaming conditions are established), the gaming state of the pachinko machine 10 is switched by opening the lid 20a of the big prize opening 20. Therefore, even if the pachinko ball is fired in synchronization with one cycle of the counter as in the conventional case, the gaming state intended by the player who intends to cheat (in this example, it is a big hit state. The same applies hereinafter. ) Will not switch. For the player, it is not known when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

  In addition, the specific condition may or may not be satisfied once or a plurality of times, and the count value N of the free counter 105 also changes complicatedly depending on the gaming state. Thus, the count value C of the counter 111 changes irregularly depending on the number of times the specific condition is satisfied and the count value N. Since the jackpot interval thus changes in a complicated manner (that is, variously), it becomes extremely difficult to match the timing of winning the pachinko ball to the first type starting port 18 with the jackpot timing. Therefore, illegal games can be prevented. Furthermore, the count value C changes differently from the normal change at indefinite timing (for example, times t12 and t18 shown in FIG. 8A). At this time, the range in which the count value C changes also depends on the count value N of the free counter 105. For this reason, the player does not know when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

In addition, you may apply as shown below. In these cases, any illegal game can be prevented.
(A1) The length of the transition period may be changed only once compared with the other transition periods, and thereafter, the length of the transition period may be changed. Even in this case, the player does not know how much the jackpot interval has changed.
(A2) The specific condition may be satisfied at a predetermined timing (for example, after a predetermined period has elapsed since the count value C is the start value Cmin). Even in this case, the player cannot know how much the jackpot interval has changed depending on the count value N of the free counter 105.
(A3) When the specific condition is satisfied at an indefinite timing, a predetermined value stored in advance in the ROM 102 (or RAM 104) is added (or subtracted) to the count value C instead of the count value N of the free counter 105. May be. Even in this case, it is not known how much the count value C changes from a normal change. Therefore, the player does not know how much the jackpot interval has changed.
(A4) As shown in FIG. 8B, the count value C may be decreased based on the count value N at times t24 and 26 when the specific condition is satisfied. In this case, it starts to increase from the start value Cmin at time t10, decreases at intermediate times t24 and 26, reaches the end value Cmax at time t28, and is initialized to the start value Cmin. The jackpot interval in the change pattern P4 is substantially equal to the period from time t10 to time t28. In this embodiment, the big hit interval is longer than before. Since the jackpot interval changes in this way, it becomes difficult to match the timing of winning the pachinko ball to the first type starting port 18 with the jackpot timing. Note that, based on the count value N, the increasing mode shown in FIG. 8A and the decreasing mode shown in FIG. In this case, the big hit interval changes in a more complicated manner depending on the amount of mixing, the increase value, the decrease value, or the like. Therefore, it becomes more difficult to match the timing of winning the pachinko ball to the first type starting port 18 with the jackpot timing.

[Embodiment 2]
Next, a second embodiment in which the change from the start value to the end value is temporarily stopped will be described with reference to FIG. Here, in FIG. 9, FIG. 9A shows a flowchart of the second main process, and FIG. 9B shows a change in count value with time in a time chart. In addition, since the structure of the pachinko machine 10 and the main control part 100 is the same as that of the said Embodiment 1, the description is abbreviate | omitted. Therefore, differences from the first embodiment will be described.

  The main process shown in FIG. 9A is a process that replaces the main process shown in FIG. In FIG. 9A, first, it is determined whether or not a specific condition is satisfied [step S10]. If the specific condition is not satisfied (NO), the count process Pa is executed [step S12]. Thereafter, a game process for a pachinko game is performed [step S16]. On the other hand, when the specific condition is satisfied (YES), the game process is performed without doing anything [step S16]. And it waits until interval (DELTA) t passes after starting to perform step S10 [step S20], and returns to step S10. In this way, steps S10, S12, S16, and S20 are repeatedly executed.

  When the main process shown in FIG. 9A is executed, the count value C becomes a change pattern P6 indicated by a solid thick line as shown in FIG. 9B. That is, when step S12 is executed, it increases from the start value Cmin at time t10. Then, between time t30 and time t32, the specific condition is satisfied and step S12 is not executed, and the count value C is held. Thereafter, it increases again, reaches the end value Cmax at time t34, and is initialized to the start value Cmin. Then, it starts increasing from the start value Cmin again at time t34. Thereafter, every time the specific condition is satisfied, the count value C is held. The jackpot interval in the change pattern P6 is substantially equal to the period from time t10 to time t34. In this aspect, since the count value C is held between the time t30 and the time t32, the big hit interval is longer than before.

  According to the second embodiment, the count value C is held for an indefinite period at an indefinite timing. Therefore, the transition period is extended and the jackpot interval is also changed. Since the jackpot interval changes in this way, the illegal game of the pachinko machine 10 can be prevented as in the first embodiment. Note that the timing at which the count value C is held may be a predetermined timing. Similarly, the period for holding the count value C may be a predetermined period. In any case, since the transition period is extended and the jackpot interval is also changed, the illegal game can be prevented.

[Embodiment 3]
Next, Embodiment 3 in which the change direction is temporarily changed until the count value reaches the end value from the start value will be described with reference to FIG. Here, in FIG. 10, FIG. 10A shows a flowchart of the third main process, and FIG. 10B shows a change in count value with time in a time chart. In addition, since the structure of the pachinko machine 10 and the main control part 100 is the same as that of the said Embodiment 1, the description is abbreviate | omitted. Therefore, differences from the first embodiment will be described.

  The main process shown in FIG. 10A is a process that replaces the main process shown in FIG. In FIG. 10A, it is first determined whether or not a specific condition is satisfied [step S10]. If the specific condition is satisfied (YES), after the sign of the change value X is reversed [Step S11], the count process Pa is executed [Step S12]. On the other hand, when the specific condition is not satisfied (NO), the count process Pa is executed without doing anything [step S12]. After executing step S12, a game process for a pachinko game is performed [step S16]. And it waits until interval (DELTA) t passes after starting to perform step S10 [step S20], and returns to step S10. In this way, steps S10, S11, S12, S16, and S20 are repeatedly executed.

  When the main processing shown in FIG. 10A is executed, the count value C becomes a change pattern P8 indicated by a solid thick line as shown in FIG. 10B. That is, when step S12 is executed, it increases from the start value Cmin at time t10. Then, at time t40 and t42, the specific condition is satisfied and step S11 is executed, and the sign of the change value X is changed. Therefore, the count value C changes from time t10 to t40 and time t42 to t44 in the increasing direction, and from time t40 to t42 in the decreasing direction. Thereafter, at time t44, the end value Cmax is reached and initialized to the start value Cmin. Then, it starts increasing from the start value Cmin again at time t44. Thereafter, every time the specific condition is satisfied, the sign of the change value X changes, and the count value C increases or decreases. The jackpot interval in the change pattern P8 is substantially equal to the period from time t10 to time t44. In this example, the time t16 is restored to the same value as the count value C at the time t40. Therefore, the big hit interval is longer than the conventional one for the period from time t40 to time t16.

  According to the third embodiment described above, the count value C is changed by changing the changing direction only for an indefinite period at an indefinite timing. Therefore, the transition period is extended and the jackpot interval is also changed. Since the jackpot interval changes in this way, the illegal game of the pachinko machine 10 can be prevented as in the first embodiment. Note that the timing at which the change direction of the count value C is changed may be a predetermined timing. Similarly, the period for holding the count value C may be a predetermined period. In any case, since the transition period is extended and the jackpot interval is also changed, the illegal game can be prevented.

[Embodiment 4]
Next, Embodiment 4 in which the start value and / or the end value is changed will be described with reference to FIGS. FIG. 11 is a flowchart showing the fourth main process. FIGS. 12 and 13 show time-dependent changes in the count value, respectively. In addition, since the structure of the pachinko machine 10 and the main control part 100 is the same as that of the said Embodiment 1, the description is abbreviate | omitted. Therefore, differences from the first embodiment will be described.

  The main process shown in FIG. 11 is a process that replaces the main process shown in FIG. In FIG. 11, first, a count process Pa for counting up the count value C of the counter 111 by 1 is executed [step S12], and then a game process for a pachinko game is performed [step S16]. Then, a count process Pc for incrementing the count value N of the free counter 105 by 1 is executed [step S18] until the interval Δt elapses after the start of execution of step S12 [step S20]. When the interval Δt has elapsed, it is determined whether or not the count value C has reached the end value Cmax [step S22]. That is, the determination is made based on whether or not C ≧ Cmax is satisfied. If the count value C reaches the end value Cmax (YES), the start value Cmin and / or the end value Cmax are changed based on the count value N [step S24]. That is, at least one of Cmin = Cmin + N, Cmin = Cmin−N, Cmax = Cmax + N, and Cmax = Cmax−N is executed. After execution of step S24 or when the count value C has not reached the end value Cmax (NO in step S22), the process returns to step S12. Thus, steps S12, S16, S18, S20, S22, and S24 are repeatedly executed.

  In the main process shown in FIG. 11, when the end value is changed by executing Cmax = Cmax + N in step S24, the count value C becomes a change pattern P10 indicated by a solid bold line as shown in FIG. That is, when step S12 is executed, it increases from the start value Cmin at time t10, reaches the end value (Cmax + N) at time t50, and is initialized to the start value Cmin. Then, it starts increasing from the start value Cmin again at time t50. The jackpot interval in the change pattern P10 is substantially equal to the period from time t10 to time t50. In this example, the big hit interval is longer than the conventional value by the count value N. Similarly, when the end value is changed by executing Cmax = Cmax−N in step S24, the count value C becomes a change pattern P12 indicated by a solid bold line as shown in FIG. In this example, the big hit interval is shorter than the conventional one by the count value N corresponding to the end value.

  Further, when the start value is changed by executing Cmin = Cmin + N in step S24, the count value C becomes a change pattern P14 indicated by a solid bold line as shown in FIG. In this example, the big hit interval is shorter than the conventional one by the count value N corresponding to the end value. Further, when the start value is changed by executing Cmin = Cmin−N in step S24, the count value C becomes a change pattern P16 indicated by a solid bold line as shown in FIG. In this example, the big hit interval is longer than the conventional one by the count value N of the start value.

  According to the four aspects in the fourth embodiment, when the count value C reaches the end value Cmax (predetermined timing), the start value Cmin and / or the end value Cmax are changed. Therefore, the transition period expands and contracts, and the big hit interval also changes. Since the jackpot interval changes in this way, the illegal game of the pachinko machine 10 can be prevented as in the first embodiment. If these four modes are arbitrarily mixed and executed, the jackpot interval changes more variously. Further, even when the start value and the end value are changed at the same time, the jackpot interval similarly changes more variously. Furthermore, the start value Cmin and / or the end value Cmax may be changed at indefinite timing. In any case, since the transition period expands and contracts and the jackpot interval also changes, illegal games can be prevented.

[Embodiment 5]
Next, Embodiment 5 in which the change value (change rate) of the count value is changed will be described with reference to FIGS. FIG. 14 is a flowchart showing the fifth main process. FIG. 15 is a time chart showing changes with time of the count value. In addition, since the structure of the pachinko machine 10 and the main control part 100 is the same as that of the said Embodiment 1, the description is abbreviate | omitted. Therefore, differences from the first embodiment will be described.

  The main process shown in FIG. 14 is a process that replaces the main process shown in FIG. In FIG. 14, first, a count process Pb for counting up the count value C of the counter 111 based on the change value X is executed [step S14], and then a game process for a pachinko game is performed [step S16]. Then, the count value N of the free counter 105 is incremented by 0.1 (may be another real value such as 0.01) from the start of execution of step S14 until the interval Δt has passed [step S20]. The counting process Pc is executed [step S18]. When the interval Δt has elapsed, it is determined whether or not the count value C has reached the end value Cmax [step S22]. That is, the determination is made based on whether or not C ≧ Cmax is satisfied. If the count value C reaches the end value Cmax (YES), the change value X is changed based on the count value N [step S26]. That is, X = N is executed. After execution of step S26, or when the count value C has not reached the end value Cmax (NO in step S22), the process returns to step S14. In this way, steps S14, S16, S18, S20, S22, and S26 are repeatedly executed.

  When the main process shown in FIG. 14 is executed, the count value C becomes a change pattern P18 indicated by a solid bold line as shown in FIG. That is, when step S12 is executed, the value increases from the start value Cmin corresponding to the change value X (where X> 1) at time t10. At time t70, the end value Cmax is reached and initialized to the start value Cmin. Then, it again starts increasing from the start value Cmin at time t70, and reaches the end value Cmax at time t72. The big hit interval in the change pattern P18 is approximately equal to the period from time t10 to time t70 in the first cycle, and is approximately equal to the period from time t70 to time t72 in the second cycle. In this example, the big hit interval is shorter than before in any period. On the other hand, when the change value X is 0 <X <1, the count value C becomes a change pattern P20 indicated by a solid thick line as shown in FIG. The jackpot interval in the change pattern P20 is substantially equal to the period from time t10 to time t74. In this example, the big hit interval is longer than before.

  According to the fifth embodiment, when the count value C reaches the end value Cmax (predetermined timing), the change value X is changed to change the count value C. Therefore, the transition period expands and contracts, and the big hit interval also changes. Since the jackpot interval changes in this way, the illegal game of the pachinko machine 10 can be prevented as in the first embodiment. The timing for changing the change value X may be an indefinite timing. Even in this case, since the transition period expands and contracts and the jackpot interval also changes, illegal games can be prevented.

[Embodiment 6]
Next, a sixth embodiment for realizing the present invention using a counter block will be described with reference to FIGS. Here, FIG. 16 is a block diagram showing the configuration of the second control unit. FIG. 17 shows the configuration of the counter block. FIG. 18 shows the configuration of the oscillator. FIG. 19 is a flowchart showing the processing contents performed in the counter block. In addition, since the structure of the pachinko machine 10 is the same as that of the said Embodiment 1, the description is abbreviate | omitted. Therefore, differences from the first embodiment will be described.

  A main control unit 100 shown in FIG. 16 is a control unit that replaces the main control unit 100 shown in FIG. The difference from FIG. 2 is that the counter is realized by the counter block 106. The configuration of the counter block 106 is shown in FIG. In FIG. 17, the counter block 106 includes a counter 107c, a comparator 107d, and a setting register 107e. A configuration example of the oscillator 107a will be described later. The counter 107c receives the pulse signal output from the oscillator 107a and counts up the count value N. The counter 107c receives the clear signal output from the setting register 107e, and initializes the counter with the start value Nmin. Further, the counter 107 c receives the read signal output from the CPU 110 via the bus 118 and sends the count value N at that time via the bus 118. The setting register 107e temporarily records (stores) a setting value set through the bus 118 from the CPU 110 (or the frame control unit 200, the hall computer 300, or the like). This set value specifically corresponds to the end value Nmax. The comparator 107d outputs a clear signal when the count value N of the counter 107c matches the set value of the setting register 107e, and outputs nothing when it does not match.

  Here, an example in which the oscillator 107a is configured by a self-excited oscillation circuit is shown in FIG. Here, FIG. 18A shows an oscillator circuit configuration using a crystal resonator, FIG. 18B shows an oscillator circuit configuration using a resistor and a capacitor, and FIG. 18C shows an inverter. The circuit configurations of the oscillators connected in multiple stages are shown respectively.

  The oscillator shown in FIG. 18A includes inverters (NOT circuits) Q10 and Q12, a resistor R10, a crystal resonator XL, and capacitors C10 and C12. A resistor R10 and a crystal resonator XL are connected in parallel to both ends of the inverter Q10, and are further connected to the ground via capacitors C10 and C12. An inverter Q12 is connected in series to the inverter Q10, and a pulse signal PL is periodically output from the output side of the inverter Q12. In this oscillator, the period of the pulse signal PL depends on the oscillation frequency of the crystal unit XL. Note that other types of vibrators such as ceramic vibrators may be used in place of the quartz crystal vibrator XL.

  The oscillator shown in FIG. 18B includes inverters Q14 and Q16, a resistor R12, and a capacitor C14. A resistor R12 is connected in parallel to both ends of the inverter Q14. Further, the capacitor C14, the inverter Q14, and the inverter Q16 are connected in series in this order from the ground side. One side of the capacitor C14 not connected to the inverter Q14 is connected to the ground, and the pulse signal PL is periodically output from the output side of the inverter Q16. Note that a value obtained by multiplying the capacitance value of the capacitor C14 and the resistance value of the resistor R12 (= C14 × R12) is a time constant and is substantially equal to the cycle of the output pulse signal PL.

  The oscillator shown in FIG. 18C includes four inverters Q18, Q20, Q22, and Q24. These inverters Q18, Q20, Q22, Q24 are connected in series. Further, the output side of inverter Q22 is connected to the input side of inverter Q18 to form a feedback loop. Then, the pulse signal PL is periodically output from the output side of the inverter Q24. In this example, the inverters are connected in four stages, but the inverters can be connected in multiple stages (several tens to several hundreds). Each inverter is delayed by a minute time until the input pulse signal is output, and this delay time Δd is proportional to the number of inverters connected in multiple stages. Therefore, a value obtained by multiplying the inverter stage number n by the delay time Δd (= n × Δd) is substantially equal to the cycle of the output pulse signal PL.

  The counter block 106 having the above-described configuration is processed according to the procedure of the count process Pd shown in FIG. This count process Pd is executed in place of the count process Pc shown in FIG. In FIG. 19, first, it is determined whether or not the pulse signal output from the oscillator 107a has been received [step S70]. If no pulse signal is received (NO), the process proceeds to step S80 without doing anything. In this case, the count value N of the counter 107c remains held. On the other hand, when a pulse signal is received (YES in step S70), it is determined whether or not a stop signal is received from the CPU 110 [step S72]. If a stop signal is received (YES), the process proceeds to step S80. Also in this case, the count value N of the counter 107c remains held. On the other hand, when the stop signal is not received (NO in step S72), the count value N is incremented [step S74]. Specifically, the calculation of N = N + 1 is performed. Then, it is determined whether or not the count value N has reached the end value Nmax [step S76]. Specifically, the determination is made based on whether or not N ≧ Nmax is satisfied. If the count value N reaches the end value Nmax (YES), the count value N is initialized with the start value Nmin [step S78]. Specifically, N = Nmin is substituted. This start value Nmin is set in advance in the counter 107c directly from the CPU 110. Note that the start value Nmin may be changed in a timely manner as necessary. On the other hand, when the count value N has not reached the end value Nmax (NO in step S76), the process proceeds to the next step S80 without doing anything.

  Next, it is determined whether or not a clear signal is received from the comparator 107d [step S80]. If no clear signal has been received, the process proceeds to step S84. Also in this case, the count value N of the counter 107c remains held. On the other hand, when a clear signal is received (YES), the count value N of the counter 107c is initialized with the start value Nmin as in step S78 [step S82]. And it is discriminate | determined whether the read signal was received from CPU110 [step S84]. If no read signal is received (NO), the process directly returns to step S70. On the other hand, when a read signal is received (YES), the count value N is sent to the CPU 110 via the bus 118 [step S86], and then the process returns to step S70. Depending on the processing contents, the count value N is normally counted up in step S74, and the CPU 110 can obtain the count value N by outputting a read signal to the counter 107c. Further, when the count-up is stopped and the count value N is held, a stop signal may be output to the counter 107c. Furthermore, the start value Nmin can be set in the counter 107c, and the end value Nmax can be set in the setting register 107e, respectively. Therefore, the start value Nmin and / or the end value Nmax can be changed in a timely manner.

  According to the sixth embodiment, the pulse value output from the oscillator 101 (first oscillator) is received, and the count value C (first count value) of the counter 111 (first counter) is set to the start value Cmin (first count). The value is regularly changed from 1 start value) to the end value Cmax (first end value) (see FIG. 3). Further, in response to a pulse signal output from the oscillator 107a (second oscillator) that operates at a higher speed than the oscillator 101, the count value N (second count value) of the counter 107c (second counter) is set to the start value Nmin (first value). 2) until the end value Nmax (second end value) is reached (see FIG. 19). Therefore, the count value C of the counter 111 and the count value N of the counter 107c are updated at different speeds. Then, at an indefinite timing, the count value C of the counter 111 is changed based on the count value N of the counter 107c (step S14 shown in FIG. 3). For this reason, the count value C often changes greatly at indefinite timing. Further, when the big winning symbol is displayed on the special symbol display 42 (predetermined gaming condition is established), the gaming state of the pachinko machine 10 is switched by opening the lid 20a of the big winning opening 20. Here, since the oscillator 107a is configured by the self-excited oscillation circuit shown in FIG. 18, the interval between the pulse signals PL cannot be obtained with such high accuracy and becomes non-uniform. This tendency becomes more prominent as the inaccurate oscillator 107a is used. Further, the cycle (corresponding to the transition period) for initializing the counter 107c is also nonuniform. Therefore, the count value N obtained by executing steps S74 and S82 shown in FIG. 19 is also non-uniform. Furthermore, since the big hit interval is also non-uniform, even if the pachinko ball is fired in accordance with one cycle of the counter as in the prior art, it does not switch to the gaming state intended by the player who intends to cheat. Of course, the player does not know when and how much the jackpot interval changes. Therefore, illegal games can be prevented more reliably.

In addition, you may apply as shown below. In these cases, any illegal game can be prevented.
(B1) The counter 107c may receive a pulse signal output from the oscillator 101 shown in FIG. 2 instead of the oscillator 107a shown in FIG. 17 (indicated by a two-dot chain line in FIGS. 16 and 17). In this case, the oscillation frequencies of the oscillator 101 and the oscillator 107a may be the same or different. However, it is desirable that the oscillator 107 a has a higher frequency than the oscillator 101. In this way, the jackpot interval can be significantly changed. The oscillator 101 may have a higher frequency than the oscillator 107a. The configuration of the oscillator 101 may be any one of the three modes shown in FIG. In this case, the pulse signal easily changes irregularly. Therefore, in each of the first to fifth embodiments, the transition period is likely to be irregular. In this way, the jackpot interval can be changed irregularly.
(B2) A frequency divider 107b that divides and outputs the pulse signal output from the oscillator 107a (oscillator 101) may be provided between the oscillator 107a (oscillator 101) and the counter 107c shown in FIG. . The frequency divider 107b divides the pulse signal based on the frequency division value set through the bus 118 from the CPU 110 (or the frame control unit 200, the hall computer 300, etc.). When the frequency division value is changed to an appropriate time, the transition period expands and contracts and the jackpot interval also changes.
(B3) The setting value set in the setting register 107e is more preferably set to a value different between the pachinko machines 10. For example, the set value is specified based on data such as an ID number and a manufacturing number recorded in the CPU 110. By doing so, the period (that is, the transition period and the big hit interval) for initializing the counter 107c can be made different for each pachinko machine 10. Therefore, even if the counting cycle is found in a certain pachinko machine by unauthorized means such as a sensory device, the timing cannot be adjusted because the counting cycle of other pachinko machines is different. Therefore, it is very unlikely that other pachinko machines will be “winning”, and it is possible to minimize illegal games.
(B4) It is desirable to use resistors R10, R12 and capacitors C10, C12, C14 shown in FIGS. 18A and 18B with low accuracy. Moreover, a carbon resistor or a metal film resistor is used for the resistors R10 and R12. Instead of these types of resistors, a thermistor whose resistance value is likely to change according to the ambient temperature may be used. Further, variable capacitors may be used for the capacitors C10, C12, and C14. This makes it easier to make the cycle of the output pulse signal PL more irregular. For this reason, the transition period and the jackpot interval become more irregular. Therefore, since the timing of the player who tries to play the illegal game can be greatly removed, the illegal game can be prevented.

[Other Embodiments]
In the gaming machine control device described above, the structure, shape, size, material, number, arrangement, operating conditions, and the like of other parts are not limited to the above embodiment. For example, each of the following embodiments to which the above embodiment is applied can be implemented.

(1) In the fifth embodiment, the change value X is changed at a predetermined or indefinite timing. The change value X may be changed at a predetermined timing (for example, every interval Δt) based on the function. For example, the function f is defined as follows: [Expression 1] f = AeBx + C (e is a natural logarithm, A, B, and C are constants, and x is a variable) At this time, a count value C is given as a variable x. In addition, the function f may be expressed by a multiple polynomial. When the change value X is changed based on such a function f, for example, a change pattern P22 shown in FIG. 20 is obtained. In this example, the first cycle from time t10 to time ta2 and the second cycle from time ta2 to time ta4 are changed based on different functions f. In any case, since the transition period expands and contracts and the jackpot interval also changes, illegal games can be prevented. Note that the change value X may be changed based on the same function f. Further, the correspondence relationship in the data table TB2 shown in FIG. 4, the data table TB4 shown in FIG. 5, and the data table TB6 shown in FIG. 7 may be a relationship obtained by the function f. In this way, it is not necessary to perform the calculation every time, and the processing speed is improved.

(2) In each of the above embodiments, the count value C is changed within the range between the start value Cmin and the end value Cmax (that is, Cmin ≦ C ≦ Cmax). However, the present invention is not limited to this mode, and the start value Cmin and the end value Cmax may be changed beyond the range. Specifically, it can be realized by appropriately determining the function f. An example thereof is shown by a change pattern P24 in FIG. In this example, the count value C exceeds the end value Cmax between time tb2 and time tb4. Also in this case, since the transition period expands and contracts and the jackpot interval also changes, illegal games can be prevented.

(3) In the first embodiment, the count value C is decreased based on the count value N when the specific condition is satisfied, and the time when the count value C reaches the end value Cmax is not limited (FIG. 8 ( B)). Instead of this form, the time when the count value C reaches the end value Cmax may be limited to a certain period. An example thereof is shown by a change pattern P26 in FIG. In this example, the count value C decreases at times tc0, tc2, tc4, tc6, and tc8, and the count value C is initialized with the start value Cmin in a period corresponding to the period from time t10 to time t16. . In this case, the number of times the count value C coincides with the hit value Hit changes during a certain period, and the period from a certain hit to the next hit changes. Therefore, even if a pachinko ball is fired in synchronization with one cycle of the counter as in the conventional case, the game state is not switched to a state intended by a player who intends to cheat. For the player, it is not known when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

(4) In each of the above-described embodiments, the “winning” in the claims is a big hit. That is, the present invention is applied to a state in which the special symbol stopped and displayed on the special symbol display 42 after the change matches the jackpot symbol. In addition to (or instead of) this form, “winning” may be applied to a normal hit, that is, applied to a state where the normal symbol displayed on the normal symbol display 40 after the change matches the winning symbol. Good. Even in these cases, the illegal game of the pachinko machine 10 can be prevented as in each embodiment.
(5) In the first embodiment, the counter 111 is provided in the CPU 110 in FIG. Instead of this form, the count value may be stored in a recordable / updatable recording medium. As a recording medium, a RAM 104 (indicated by a two-dot chain line in FIG. 2), a frame control unit 200, a hall computer 300, cards (a prepaid card, an IC card, a paper card, etc.), or a printed matter on which characters or symbols are printed. Etc. The mode of recording on this recording medium can also be applied to the frequency division value and the function f.

(6) The oscillator 101 outputs a pulse signal at a substantially constant cycle. Instead of the oscillator 101, an oscillator that outputs a signal other than the pulse signal (for example, an analog signal such as a sine wave signal) may be used. Further, instead of the oscillator 101 and / or the oscillator 107a, a noise detection device that detects external noise and outputs a pulse signal may be used. This noise detection device includes, for example, an antenna (including a lead wire or a metal member corresponding to the antenna), an amplification circuit that amplifies a signal received by the antenna, and when the amplified signal reaches a predetermined level. It is constituted by a signal output circuit that outputs a pulse signal.
(7) In each of the above embodiments, the count value C is changed based on the count value N of the free counter 105 (for example, step S14 shown in FIG. 3). Instead of the count value N, the count value C may be changed based on the count value sent from the frame control unit 200 or the hall computer 300 to the pachinko machine 10 via the communication line.

(8) In each of the above-described embodiments, the count value C of the counter 111, the count value N of the free counter 105, and the count value N of the counter 107c are all counted up. Instead of this form, it may be applied to an aspect in which at least one count value is counted down. In this case, the count value is subtracted by 1 or N or the change value X. The start value is Cmax or Nmax, and the end value is Cmin or Nmin. Therefore, the count value is initialized with Cmax or Nmax. Further, the value to be initialized is not limited to the start value, and may be an arbitrary value (for example, 100). Furthermore, the count-up and count-down may be switched as appropriate so that the count-up is performed in a certain cycle and the count-down is performed in another certain cycle. Even in these modes, the transition period expands and contracts, and the jackpot interval also changes. Since the jackpot interval changes in this way, illegal gaming of the pachinko machine 10 can be prevented. Further, the counter may be a k-ary n-digit counter and a m-digit value accessible from the CPU 110 or the like. Here, k, n, and m are all integers, and a relationship of k> 1, n> 1, n> m> 1 is established. In this case, initialization is performed within a range of m digits. For example, when a decimal 4 digit (k = 10, n = 4) counter is used, a value of 0000 to 9999 can be taken. At this time, if the value accessible from the CPU 110 or the like is 3 digits (m = 3), the possible value is 000 to 999. In this example, the counter becomes 1000 when counting up next to 0999, but it is initialized from 999 to 000 when viewed from the CPU 110 or the like. This is the same even when counting down. Thus, the value obtained by the CPU 110 or the like can be initialized as a result without positively initializing the counter with a clear signal or the like. The same applies to a counter in which at least one digit of the n-digit counter is another progressive number. For example, there is a counter in which the last two digits of the decimal five-digit counter are processed by binary numbers. Further, it is more preferable that the pulse signal output from the oscillator 107a is divided by the frequency divider 107b and sent to the counter as in the sixth embodiment (see FIG. 17), in that the count cycle changes variously.

(9) In the first to fifth embodiments, the present invention is realized by software, but may be realized by hardware. For example, there are a hardware logic circuit, a gate array, an ECL circuit, a TTL circuit, and the like. Further, it can be realized by a microprogram in firmware.
(10) In each of the above embodiments, the winning value (including the jackpot value) is not changed, but the winning value may be changed at a predetermined or indefinite timing. In this way, the timing at which the count value matches the hit value before the count value reaches the end value is different. Therefore, since the period from one hit to the next hit changes, even if a pachinko ball is fired according to one cycle of the counter as in the past, a game intended by a player who intends to cheat It does not switch to the state. For the player, it is not known when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

(11) In each of the above embodiments, the present invention is applied to the pachinko machine 10. Not limited to this, a symbol display unit (normal symbol display 40 and / or special symbol display 42) capable of displaying a symbol is provided, and the symbol is displayed after changing the symbol in the symbol display unit. Can be applied to other gaming machines that provide a special benefit to the player as a hit when the symbol matches the predetermined symbol. Examples of other gaming machines include an arrange ball machine and a video game machine.

[Other Aspects of Invention]
Although the embodiment of the present invention has been described above, this embodiment has not only the embodiment of the invention described in the claims but also other embodiments of the invention. Aspects of the present invention are listed below, and related explanations are given as necessary.

[Aspect 1]
In response to a signal output from the oscillator, the count value of the counter is irregularly changed from the start value to the end value, and when a predetermined gaming condition is satisfied, the gaming state of the gaming machine is based on the count value at that time A control device for gaming machines that switches between.
[Related description of aspect 1]
According to this aspect, when the count value of the counter is changed irregularly, the hit interval also changes. In this case, since the winning interval changes irregularly, it becomes very difficult to match the timing of winning or passing with the timing of “winning”. Therefore, illegal games can be prevented.

[Aspect 2]
In response to the signal output from the first oscillator, the first count value of the first counter is regularly changed from the first start value to the first end value, and operates at a higher or lower speed than the first oscillator. In response to the signal output from the second oscillator, the second count value of the second counter is changed from the second start value to the second end value, and when a predetermined or indefinite timing is reached, the second count value is reached. A control device for a gaming machine that changes a first count value based on a value and switches a gaming state of the gaming machine based on a first count value at that time when a predetermined gaming condition is established. [Related description of aspect 2]
According to this aspect, when the first count value of the first counter that changes regularly is changed to the second count value of the second counter at a predetermined or indefinite timing, the length of the transition period in the first counter is also increased. It expands and contracts. This changes the winning interval in the first counter, making it difficult to match the winning timing. Further, since the change value changes at a predetermined or indefinite timing, the player does not know when and how much the length of the transition period changes. Therefore, illegal games can be prevented.

[Aspect 3]
10. The gaming machine control device according to claim 2 or claim 9, wherein the first oscillator and / or the second oscillator outputs a signal irregularly.
[Related description of aspect 3]
According to this aspect, the first count value of the first counter and / or the second count value of the second counter are irregularly changed by the first oscillator and / or the second oscillator. When the first count value is changed to the second count value at a predetermined or indefinite timing, the length of the transition period in the first counter is also expanded or contracted. This further changes the winning interval in the first counter, making it very difficult to match the winning timing. Further, since the change value changes at a predetermined or indefinite timing, the player does not know when and how much the length of the transition period changes. Therefore, illegal games can be prevented more reliably.

[Aspect 4]
In response to the signal output from the oscillator, the count value of the counter is changed from the start value to the end value, and the length of the period from when the count value reaches the winning value until the next winning value is reached. A control device for a gaming machine that changes a gaming state of a gaming machine when a predetermined gaming condition is satisfied and the count value matches a winning value, at least once.
[Related description of aspect 4]
According to this aspect, the timing at which the count value matches the winning value is different at least once before the count value reaches the end value. Therefore, since the period from one hit to the next hit changes, even if a pachinko ball is fired in accordance with one cycle of the counter as in the past, a player who intends to cheat is intended. Does not switch to gaming state. For the player, it is not known when and how much the length of the transition period changes. Therefore, illegal games can be prevented.
