Description

  The present invention relates to a gaming machine.

  Conventionally, a reel in which a plurality of types of symbols are arranged is rotated by a stepping motor operated by excitation control, and the reels are controlled to stop based on a predetermined stop instruction, and the symbols are stopped on a predetermined winning line by the stop control. There is known a gaming machine that grants a privilege corresponding to a combination when the combination is established (see, for example, Patent Document 1).

Such a stepping motor has a configuration in which a plurality of stators are arranged around a rotor made of a magnetic body rotatably supported, and the rotor is rotated by sequentially switching the excitation state of the stator. Yes. Information for controlling switching of the excitation state of the stator is the excitation control step. Each of the excitation control steps is defined in one-to-one correspondence with the excitation state of the stator. The excitation control step proceeds in a predetermined order. For this reason, every time the excitation control step proceeds, the stator is excited so as to be in a corresponding excitation state. For example, when four-phase (A-phase, B-phase, A ^- phase, B ^- phase) stators are arranged and rotation control is performed by the 1-2 phase excitation method, B is set at excitation control step = 1. ^- phase and excites the two phases of the a phase, excites the first phase of the a-phase at excitation control step = 2, excitation control steps such to excite the two phases of the a-phase and B-phase at excitation control step = 3 One-phase or two-phase excitation according to the above is performed.

  Each time this excitation control step proceeds, the rotor rotates a predetermined angle. For example, in a configuration in which the excitation control step takes one round in 8 steps 1 to 8 and the rotor makes one revolution in 63 rounds, the step angle that is the rotation angle per one excitation control step of the rotor is about 0.7 degrees. become.

  The reel fixed to the rotor shaft rotates according to the rotation of the rotor. The rotational position management step is information indicating the rotational position of the reel. The rotational position management step is added in accordance with the progress of the excitation control step, and is initialized when the sensor detects that the reel has reached a specific rotational position. As described above, in the configuration in which the excitation control step makes one round in 8 steps 1 to 8 and the rotor makes one revolution in 63 rounds, when the rotational position management step is incremented for each excitation control step, 504 The rotation position management step corresponds to one rotation of the reel.

When stopping the stepping motor, the rotor of the stepping motor is made inertial by performing all-phase excitation that simultaneously excites all phases (A phase, B phase, A ^- phase, B ^- phase) of the stator. Is rotated by a predetermined angle to stop. Note that the amount of rotation due to inertia is determined by the weight and shape of the reel fixed to the shaft of the rotor.

  Therefore, when it is desired to stop the reel at a specific rotational position, all-phase excitation is performed at a timing that takes into account the amount of rotation due to inertia. For example, when the reel is stopped at the rotational position corresponding to the rotational position management step = 24, if the amount of rotation due to inertia corresponds to 6 rotational position management steps, all phases are performed at the timing of the rotational position management step = 18. What is necessary is just to start excitation.

  Here, it is determined that the required stop time from when the stop instruction is received until the reel stops is within a specified time (190 milliseconds). If the maximum speed of reel rotation is 80 revolutions per minute and the 504 rotational position management step corresponds to one reel rotation, the reel rotates by 127.68 rotational position management steps in 190 milliseconds. Therefore, the rotation position management step (all phase excitation start step) for starting all phase excitation is determined so that the rotation stops within 127 steps from the rotation position management step (stop instruction reception step) at the time when the stop instruction is received.

JP2013-39174A

  However, if the initialization of the rotational position management step is delayed, there is a problem that the required stop time exceeds the specified time. This point will be specifically described. Even if the rotation position management step is initialized between the stop instruction reception step and the all-phase excitation start step, if initialization is performed at the rotation position management step = 504, within the specified time The reel can be stopped. This is because the all-phase excitation start step is determined on the assumption that the rotation position management step = 504 is initialized. However, if a deviation occurs in the detection timing of the sensor and the initialization is performed after the rotational position management step = 505, the all-phase excitation start step is fixed. The start timing will be delayed.

  For example, when the number of required stop steps required from the stop instruction receiving step to the reel stop is 127, if initialization is performed at the rotational position management step = 505, the required stop time is one step after the initialization delay. The specified time will be exceeded.

  The deviation of the detection timing of the sensor is caused by the rise and fall of the sensor output being unstable and difficult to detect. The arithmetic unit of the gaming machine performs an interrupt process at a predetermined cycle, and the reading of the sensor output and the control of the stepping motor are performed within this interrupt process. Therefore, if the sensor output is unstable and the rising edge detection fails, the detection cannot be performed until the next interrupt process.

  Specifically, the processing unit of the gaming machine is set with an interrupt process so that control in units of steps is possible in a state where the reel rotates at the maximum speed. If the maximum speed of reel rotation is 80 revolutions per minute and the 504 rotation position management step corresponds to one reel rotation, 60 ÷ (80 × 504) = 0.00148, so 1.5 milliseconds Interrupt processing is performed at intervals, and sensor output reading, reel rotation position management, and stepping motor excitation control are performed by this interrupt processing. For this reason, if the detection of the rising edge of the sensor output fails, the next sensor reading is performed after 1.5 milliseconds, that is, after one step, resulting in an initialization delay.

  For these reasons, when controlling the stop of a reel of a gaming machine, it has been an important issue to acquire the sensor output with high accuracy and thereby prevent the specified time from being exceeded.

  The present invention has been made in order to solve the above-described problems of the prior art, and when a reel of a gaming machine is controlled to stop, the sensor output is obtained with high accuracy, thereby preventing an excess of the specified time. With the goal.

Yes.

  Next, the structure of the variable reel display device 50 will be described. FIG. 2 is an explanatory diagram showing the structure of the variable reel display device 50 of the gaming machine 1. FIG. 2A shows the entire structure of the reel variable display device 50, and shows a state in which the reel 51c is removed to show the inside of the reel variable display device 50. FIG. FIG. 2B shows the detailed structure of the reel 51c.

  The reel 51c has 21 various symbols (symbol numbers PN = 1 to 21) around a reel frame 52c made of transparent ABS resin or the like having a plurality of spoke portions extending radially from the shaft portion and an annular frame. ) Is printed and a reel band 53c is pasted. Although the structure of the reel 51c has been described here, the reel 51a and the reel 51b have the same configuration, and the reel band 53a is attached to the reel frame 52a of the reel 51a, and the reel band 52b of the reel 51b is reel band. 53b is pasted. Note that the reel frames 52a and 52b and the reel bands 53a and 53b are not shown.

  The reels 51 a to 52 c are inserted along guide rails 61 a to 61 c corresponding to the respective reels provided above and below the case body 60 of the variable reel display device 50, and are accommodated in the case body 60.

  The reel 51c is fixed to the stepping motor 64c and rotates. For the rotation of the reel 51c, a stepping motor 64c that rotates once by supplying a pulse of 504 steps is used, and a predetermined symbol can be displayed on the reel window 30 by supplying a pulse of a predetermined number of steps. Further, a backlight device 63c provided with LEDs is provided so that light can be irradiated from the inside of the reel band 53c. Thus, by irradiating light from the inside of the reel band 53c with the backlight device 63c, the player can make the symbols on the reel band 53c stand out.

  A detection plate 54c is attached to one of the spoke portions, and a reel position detection sensor 65c can output a 1-pulse reel position detection signal every time the reel 51c rotates once. The positions of the detection plate 54c and the reel band 53c are set so that the symbol of the symbol number PN = 1 is positioned on the winning line E1 in the center of the reel window 30 at the timing when the reel position detection signal is detected.

  The reel 51c, the stepping motor 64c to which the reel 51c is fixed, the backlight device 63c, and the reel position detection sensor 65c are fixed to the base plate 62c to form one unit. In this unit, the base plate 62c is inserted along the guide rail 61c and accommodated in the case body 60.

  Although the stepping motor 64c, the backlight device 63c, the detection plate 54c, and the reel position detection sensor 65c are not shown, the reel 51c has a stepping motor 64a, a backlight device 63a, a detection plate 54a, and a reel position detection sensor 65a, respectively. Correspondingly, the reel 51b corresponds to the stepping motor 64b, the backlight device 63b, the detection plate 54b, and the reel position detection sensor 65b.

  Next, the internal configuration of the gaming machine 1 will be described. FIG. 3 is a configuration diagram showing the internal configuration of the gaming machine 1. As shown in FIG. 3, the gaming machine 1 includes a main control board 10 that mainly controls games and a sub-control board 20 that mainly produces effects.

  The main control board 10 includes a processor 11, a memory 12, an input / output unit 13, a clock generation circuit 14, and an integration filter 15. The processor is an arithmetic unit such as a CPU (central processing unit) and has a register 11a therein. The processor 11 uses a memory 12 as a main storage device.

  The input / output unit 13 is an interface for performing input / output of the main control board 10. The input / output unit 13 receives input based on the player's operation from the bet button 31, the start lever 32, the stop buttons 33 a to 33 c and the checkout button 34. The input / output unit 13 receives an input of a reel position detection signal indicating that the detection plates 54a to 54c are detected from the reel position detection sensors 65a to 65c. The input / output unit 13 outputs a display control signal to the information display unit 35 and outputs a control signal to the stepping motors 64a to 64c. Further, the input / output unit 13 performs input / output of the medal receiving unit 36 and the medal paying unit 37.

  The medal acceptance unit 36 includes a sensor that detects a medal inserted into the medal insertion slot 36 a and inputs a detection signal from the sensor to the input / output unit 13. In addition, when the input / output unit 13 outputs the medal insertion restriction, the medal insertion is suppressed.

  The medal payout unit 37 pays out medals from the medal payout port 37a when the input / output unit 13 outputs an instruction to pay out medals. The medal payout unit 37 includes a sensor that detects the payout medal, and inputs a detection signal from the sensor to the input / output unit 13.

  The clock generation circuit 14 is a circuit that generates a clock signal at a predetermined cycle. Specifically, the clock generation circuit 14 generates a clock signal f1 having a period of 16.5 milliseconds using a ceramic oscillator or the like, and supplies the clock signal f1 to the processor 11. The clock generation circuit 14 divides the clock signal f 1 to generate a clock signal f 2 having a 1.5 millisecond period, and supplies the clock signal f 2 to the processor 11. The clock generation circuit 14 divides the clock signal f 1 to generate a clock signal f 3 having a period of 0.5 milliseconds, and supplies it to the integration filter 15.

  The integration filter 15 performs processing for obtaining a predetermined input among the inputs received by the input / output unit 13 based on the clock signal f3 and setting a flag. Specifically, a flag is assigned to each of the reel position detection sensors 65a to 65c, and when the input of the reel position detection signal is read, the corresponding flag is set to ON. The flag is reset by an instruction from the processor.

  The processor 11 sequentially executes the main routine of the program based on the timing of the clock signal f1. Further, the processor 11 executes an interrupt process based on the timing of the clock signal f2. This interrupt processing includes reading a flag from the integration filter 15, clearing the flag of the integration filter 15, obtaining other inputs not assigned to the flag of the integration filter 15, and supplying an output signal.

  In addition, the processor 11 transmits various commands to the sub-control board 20. Based on the various commands received from the main control board 10, the sub control board 20 displays effect images associated with the game on the display 41 and outputs sound such as BGM from the speaker 42. Further, the sub control board 20 performs lighting control of the backlight devices 63a to 63c provided in the reel variable display device 50.

  Next, acquisition of input by the processor 11 and the integration filter 15 will be described. FIG. 4 is an explanatory diagram regarding the acquisition of input by the processor 11 and the integration filter 15. The integration filter 15 acquires inputs from the reel position detection sensors 65a to 65c every 0.5 milliseconds based on the clock signal f3. At this time, if a reel position detection signal is input from the reel position detection sensors 65a to 65c, the corresponding flag is turned on, that is, set to "1". If no reel position detection signal is input, the flag state is maintained.

  The processor 11 reads the flag of the integration filter 15 every 1.5 milliseconds based on the clock signal f2, and turns off the flag, that is, resets it to “0”. For this reason, the integration filter 15 acquires the input from the reel position detection sensors 65a to 65c three times before the flag is read and reset by the processor 11. If the reel position detection signal is acquired in any of the three acquisitions, the flag is set to “1”. For this reason, the processor 11 reads the logical sum of the three results obtained by the integration filter 15.

  Next, the reel control will be described. As already described, the reels 51a to 51c are fixed to the rotor shafts of the stepping motors 64a to 64c, respectively. Detection plates 54a to 54c are attached to the reels 51a to 51c, respectively. The reel position detection sensors 65a to 65c are photo sensors that detect the detection plates 54a to 54c, respectively, and output reel position detection signals when the detection plates 54a to 54c are detected.

FIG. 5 is a schematic diagram for explaining the rotation control of the stepping motors 64a to 64c. As shown in FIG. 5, the rotor (rotor) rot of the stepping motors 64a to 64c is a magnetized magnetic body and is rotatably supported by a shaft. Four windings that operate as electromagnets are disposed around the rotor rot. The four windings, A-phase, B-phase, A ^- Phase, B ^- to function as a stator (stator) Stt1～stt4 corresponding respectively to 4-phase phase. Energizing the winding and operating it as an electromagnet is called excitation. Since each winding can be individually energized, the four phases can be individually excited.

  The processor 11 rotationally drives the stepping motors 64a to 64c by the 1-2 phase excitation method. In the 1-2 phase excitation method, one-phase excitation for exciting one phase of the stator and two-phase excitation for simultaneously exciting two phases of the stator are alternately switched.

  Specifically, the processor 11 manages the excitation control steps and excites the stators stt1 to stt4 according to the excitation control steps. The excitation control step takes one of values 1 to 8, and a stator to be excited in each excitation control step is determined. Excitation in each excitation control step will be described.

The processor 11 excites the B ^- phase stator stt4 and the A-phase stator stt1 in the excitation control step = 1. By exciting these two phases, the rotor rot is attracted between the B ^- phase stator stt4 and the A-phase stator stt1.

  The processor 11 excites the A-phase stator stt1 in the excitation control step = 2. By exciting this one phase, the rotor is attracted to the rot, A phase stator stt1.

  The processor 11 excites the A-phase stator stt1 and the B-phase stator stt2 at the excitation control step = 3. By exciting these two phases, the rotor rot is attracted between the A-phase stator stt1 and the B-phase stator stt2.

Similarly, the processor 11 excites the B-phase stator stt2 at the excitation control step = 4, and excites the B-phase stator stt2 and the A ^- phase stator stt3 at the excitation control step = 5. In the control step = 6, the A ^- phase stator stt3 is excited, in the excitation control step = 7, the A ^- phase stator stt3 and the B ^- phase stator stt4 are excited, and in the excitation control step = 8. The B ^- phase stator stt4 is excited.

  If the correspondence between the excitation control step and the stator to be excited is set in this way, the rotor rot can be rotationally driven by sequentially switching from the excitation control step = 1 to the excitation control step = 8. In the schematic diagram of FIG. 5, the configuration in which the rotor rot rotates once by making one excitation control step has been described, but the stepping motors 64 a to 64 c have 63 excitation control steps. Thus, the rotor is configured to rotate once. In this case, the step angle, which is the rotation angle per one excitation control step of the rotor, is about 0.7 degrees.

  The reels 51a to 51c respectively fixed to the rotor shafts of the stepping motors 64a to 64c rotate according to the rotation of the rotor. The processor 11 manages the rotational positions of the reels 51a to 51c by the rotational position management step. The rotational position management step is added as the excitation control step proceeds, and is initialized when the reel position detection sensors 65a to 65c output reel position detection signals.

  FIG. 6 is an explanatory diagram for explaining the correspondence between the rotational position management step and the excitation control step. As shown in FIG. 6, the rotational position management step takes a value of 1 to 504. The rotational position management steps = 1-8 correspond to the excitation control steps = 1-8. Further, the rotational position management steps = 9 to 16 correspond to the excitation control steps = 1 to 8. That is, the remainder obtained by dividing the rotational position management step by 8 matches the excitation control step.

  Normally, the reel position detection sensors 65a to 65c output a reel position detection signal at the timing of the rotation position management step = 504, and the corresponding rotation position management step is initialized to zero. That is, the 504 rotation position management step corresponds to one reel rotation.

  Reel bands 53a to 53c are respectively attached to the reels 51a to 51c, and 21 symbols such as “bell” and “Replay 1” are arranged on the reel bands 53a to 53c as equally as possible. It is printed. The positions of the 21 symbols on the reel are managed by symbol numbers. The symbol numbers are from symbol number PN = 1 to symbol number PN = 21. The same symbol may be arranged at a position corresponding to a plurality of symbol numbers on the same reel.

  Since the reels 51a to 51c use stepping motors 64a to 64c that rotate once by supplying a pulse of 504 steps, when 21 symbols are arranged, the interval between the symbols becomes 24 steps.

  Further, since the symbol with the symbol number PN = 1 is positioned on the winning line E1 in the middle stage of the reel window 30 at the timing when the reel position detection signal is detected, 24 steps are advanced after the reel position detection signal is detected. If symbol number PN = 2, the symbol number PN = 2 is located in the middle part of the reel window, and if step 48 is advanced, symbol number PN = 3 is located in the middle part of the reel window. If step 480 is advanced, symbol number PN = 21. The design will be located in the middle of the reel window. In step 504, the reel position detection signal is normally detected again. Thus, by controlling the number of pulses supplied to the stepping motors 64a to 64c based on the timing at which the reel position detection signal is detected, a predetermined symbol can be positioned in the middle stage of the reel window.

  FIG. 7 is an explanatory diagram for explaining the relationship between the symbol and the rotational position management step. As shown in FIG. 7, in the rotational position management step = 0, the symbol with the symbol number PN = 1 is positioned on the winning line E1. Thereafter, when the reels 51a to 51c are rotated by 24 steps and the rotational position management step is 24, the symbol with the symbol number PN = 2 is positioned on the winning line E1.

  When the reels 51a to 51c make one rotation and the rotational position management step = 504, the symbol with the symbol number PN = 1 is positioned on the winning line E1 again. When the reel position detection sensors 65a to 65c output the reel position detection signal at this timing, the rotational position management step is initialized to zero.

When stopping control of the stepping motors 64a to 64c, all-phase excitation is performed to simultaneously excite all phases (A phase, B phase, A ^- phase, B ^- phase) of the stator of the stepping motor to be stopped. . As a result, the rotor of the stepping motor to be stopped rotates by a predetermined angle due to inertia and stops. The amount of rotation due to the inertia is determined by the weight and shape of the reels 51a to 51c fixed to the rotor shaft.

  Therefore, in order to stop the symbol determined as the stop symbol on the winning line E1, that is, to stop the reels 51a to 51c at the position corresponding to the specific rotational position management step, the timing considering the rotation amount due to inertia. All phase excitation will be performed.

  The stop symbol is determined based on the rotational position management step (stop instruction receiving step) at the timing when the stop buttons 33a to 33c are pressed. Here, it is determined that the required stop time from when the stop instruction is received until the reels 51a to 51c stop is within a specified time (190 milliseconds). If the maximum rotation speed of the reel is 80 rotations per minute and the 504 rotation position management step corresponds to one rotation of the reel, the reels 51a to 51c rotate by 127.68 rotation position management steps in 190 milliseconds. Therefore, if the number of required stop steps from the stop instruction receiving step to the reel stopping is 127 steps or less, the reels 51a to 51c can be stopped within a specified time.

  As described above, the processor 11 initializes the rotational position management step when the reel position detection signals are acquired from the reel position detection sensors 65a to 65c. Even if this initialization is performed between the stop instruction reception step and the all-phase excitation start step, if the initialization is performed at the rotational position management step = 504, the reel is stopped within the specified time. Can be made. This is because the all-phase excitation start step is determined on the assumption that the rotation position management step = 504 is initialized.

  However, there may be a delay in the timing at which the processor 11 acquires the reel position detection signal. If initialization is performed after the rotational position management step = 505 due to this delay, the all-phase excitation start step is fixed, and therefore the initialization delay is the same as the timing for starting all-phase excitation.

  FIG. 8 is an explanatory diagram for explaining the initialization delay of the rotational position management step. FIG. 8A shows a case where the processor 11 has acquired the reel position detection signal at the timing of rotational position management step = 504. FIG. 8B shows a case where the processor 11 acquires the reel position detection signal at the timing of the rotational position management step = 505.

  When receiving the stop instruction, the processor 11 determines the stop position β. At this time, it is assumed that the processor 11 is initialized at the rotational position management step = 504, and the number of required stop steps is set to 127 steps or less.

  If initialization is performed at the rotational position management step = 504 as shown in FIG. 8A, the reel can be stopped within a specified time of 190 milliseconds. However, if initialization is performed at the rotational position management step = 505 as shown in FIG. 8B, the specified time of 190 milliseconds is exceeded. This is because, since the stop position β is fixed, a delay of one step of initialization is added to the required stop step number, and the actual required stop step number is 128 steps.

  When the reel position detection sensors 65a to 65c output a reel position detection signal, the rise is unstable. In the configuration in which the processor 11 directly acquires the reel position detection signal by interrupt processing every 1.5 milliseconds, if the processor 11 fails to detect the rising edge of the reel position detection signal, the next sensor reading is 1. After 5 milliseconds, that is, after one step, an initialization delay occurs.

  Therefore, a reel position detection signal is acquired every 0.5 milliseconds by the integration filter 15 and a flag is set. According to such a configuration, the processor 11 reads the logical sum of the three acquisition results obtained by the integration filter 15, and thus can prevent detection failure of the reel position detection signal. For this reason, the initialization delay of the rotation position management step can be prevented, and the reels 51a to 51c can be stopped within a specified time.

  Next, processing of the processor 11 will be described. FIG. 9 is an explanatory diagram for the processing of the processor 11. As shown in FIG. 9A, when the processor 11 receives the clock signal f2 during the processing of the main routine, it interrupts the current processing and executes the interrupt processing. When the interrupt process ends, the processor 11 returns to the main routine process interrupted by the clock signal f2.

  FIG. 9B is a flowchart of the main routine. When the power is turned on and the main routine starts, first, the processor 11 performs an initialization process (step S101). The initialization processing in step S101 includes initialization of various interfaces, mode setting of the processor 11 itself, activation of interrupt processing, and the like.

  After step S101, the processor 11 performs main step processing (step S102). Details of the main step process will be described later. After step S102, the processor 11 performs a process that cannot be controlled by the main step process as the other process (step S103).

  After step S103, the processor 11 determines whether a predetermined time has elapsed since the start of the main step process (step S104). If the predetermined time has not elapsed (step S104; No), step S104 is repeated and the process waits. If the predetermined time has elapsed (step S104; Yes), the process proceeds to the next main step process (step S102).

  FIG. 9C is a flowchart of the interrupt process. Upon receiving the clock signal f2, the processor 11 first performs input processing (step S201). Specifically, the flag from the integration filter 15 is read, the other input not assigned to the flag of the integration filter 15 is acquired from the input / output unit 13, and the corresponding flag of the register 11a is set.

  After step S201, the processor 11 performs an interrupt step process (step S202). The interruption step process includes determination of control contents of the stepping motors 64 a to 64 c and determination of control contents of the medal reception unit 36 and the medal payout unit 37. Then, the corresponding flag of the register 11a is set according to the control content.

  After step S202, the processor 11 performs output processing (step S203). In the output process, an output process to the input / output unit 13 is performed according to the contents of the register 11a. Further, the flag of the integration filter 15 is reset. After step S203, the interrupt process ends, and the processor 11 returns to the main routine.

  FIG. 10 is an explanatory diagram of the main routine and interrupt processing. As shown in FIG. 10, the interrupt process is started in the initialization process (step S101), and then the interrupt process is called at intervals of 1.5 milliseconds. After finishing the main step process (step S102) and the other processes (step S103), the main routine enters an idling state in step S104. The main step process (step S102) and the other processes (step S103) constitute one frame. If the processing for one frame is not completed within 16.5 milliseconds, the predetermined time has already been exceeded in step S104, and the process proceeds to the next main step process (step S102) without performing idling.

  Next, the main step process (step S102) shown in FIG. 9B will be described. FIG. 11 is an explanatory diagram of the main step process shown in FIG. As shown in FIG. 11, when the main step process (step S102) is started, the processor 11 first determines whether or not the state of the main step process is the “bet state” (step S301). As a result, if the main step process is in the bet state (step S301; Yes), the processor 11 performs the bet state process (step S302) and ends the main step process.

  When the main step process is not the “bet state” (step S301; No), the processor 11 determines whether or not the main step process state is the “reel operation state” (step S303). As a result, if the main step process is in the reel operation state (step S303; Yes), the processor 11 performs the reel operation state process (step S304) and ends the main step process.

  When the main step process is not “reel operation state” (step S303; No), the processor 11 determines whether or not the main step process state is “winning determination state” (step S305). As a result, if the main step process is in the winning determination state (step S305; Yes), the processor 11 performs the winning determination state process (step S306) and ends the main step process. If the main step process is not in the “winning determination state” (step S305; No), the processor 11 ends the main step process as it is.

  Next, the bet state process (step S302) shown in FIG. 11 will be described. FIG. 12 is an explanatory diagram of the bet state process shown in FIG. As shown in FIG. 12, when the bet state process (step S302) starts, the processor 11 first determines whether or not the state of the sub-step process is the “bet acceptance state” (step S401). As a result, if the sub-step process is in the bet acceptance state (step S401; Yes), the processor 11 determines whether or not the bet flag is on (step S402).

  If the bet flag is not on (step S402; No), the processor 11 ends the bet state process. If the bet flag is ON (step S402; Yes), the processor 11 performs a bet process (step S403), shifts the sub-step process to a startable state (step S404), and ends the bet state process. To do.

  When the sub-step process is not “betting acceptance state” (step S401; No), the processor 11 determines whether or not the state of the sub-step process is “startable state” (step S405).

  As a result, if the sub-step process is not in a startable state (step S405; No), the processor 11 ends the bet state process. If the sub-step process is ready to start (step S405; Yes), the processor 11 determines whether or not the start lever flag is on (step S406).

  If the start lever flag is not on (step S406; No), the processor 11 proceeds to step S410. If the start lever flag is on (step S406; Yes), the processor 11 prohibits the betting operation (step S407), sets the reel start flag to on (step S408), and sets the main step to the reel start state. The process proceeds (step S409) and the process proceeds to step S410.

  In step S410, the processor 11 determines whether or not the settlement button flag is on. If the settlement button flag is not on (step S410; No), the processor 11 ends the bet state process. If the settlement button flag is on (step S410; Yes), the processor 11 sets the payout instruction flag on (step S411), shifts the substep to the bet acceptance state (step S412), and bets. The process ends.

  Next, the reel operation state process (step S304) shown in FIG. 11 will be described. FIG. 13 is an explanatory diagram of the reel operation state process shown in FIG. As shown in FIG. 13, when the reel operation state process (step S304) is started, the processor 11 first determines whether or not the state of the sub-step process is “a state immediately after the start” (step S501).

  If the sub-step process is in a state immediately after the start (step S501; Yes), the processor 11 generates one random value in the range of 0 to 65535 (step S502) and selects a lottery table according to the game state. (Step S503). Then, the processor 11 determines a winning group by comparing the generated random number value with the selected lottery table, and sets a winning flag for winning included in the winning group (step S504). Steps S502 to S504 are the internal lottery. After step S504, the processor 11 shifts the sub-step process to a start waiting state (step S505), and ends the reel operation state process.

  If the sub-step process is not in the state immediately after the start (step S501; No), the processor 11 determines whether or not the state of the sub-step process is “waiting for start” (step S506).

  If the sub-step process is waiting to be started (step S506; Yes), the processor 11 determines whether 4.1 seconds have elapsed from the start of rotation of the reel of the previous game (step S507). In order to prevent the player from consuming excessive medals in a short time, the minimum consumption time of one game is set to 4.1 seconds, and monitoring is performed so that 15 games or more cannot be executed in one minute.

  If 4.1 seconds have not elapsed since the start of rotation of the reel of the previous game (step S507; No), the processor 11 ends the reel operation state process. If 4.1 seconds have elapsed from the start of the rotation of the reel of the previous game (step S507; Yes), the processor 11 sets the reel start flag to on (step S508), and the sub-step process waits for the reel stop. (Step S509), and the reel operation state process is terminated.

  If the sub-step process is not in a start waiting state (step S506; No), the processor 11 determines whether or not the state of the sub-step process is a “reel stop waiting state” (step S510).

  If the sub-step process is in a reel stop waiting state (step S510; Yes), the processor 11 determines whether or not all reels have stopped (step S511). If all the reels are stopped (step S511; Yes), the processor 11 shifts the main step process to the winning determination state (step S512) and ends the reel operation state process. If the sub-step process is not in a reel stop waiting state (step S510; No), or if a rotating reel remains (step S511; No), the processor 11 ends the reel operation state process as it is.

  Next, the winning determination state process (step S306) shown in FIG. 11 will be described. FIG. 14 is an explanatory diagram of the winning determination state process shown in FIG. As shown in FIG. 14, when the winning determination state process (step S306) is started, the processor 11 first determines whether or not the state of the sub-step process is “waiting for winning determination” (step S601).

  If the sub-step process is in a winning determination waiting state (step S601; Yes), the processor 11 performs a winning line determination process (step S602). In this winning line determination process, a winning combination is determined based on whether or not the combination of the stopped symbols on the winning line E1 matches the combination of symbols corresponding to the winning combination. Is granted. After the winning line determination process, the processor 11 cancels the prohibition of the bet operation (step S603) and performs a winning flag clear process (step S604). Then, the sub-step process is shifted to a payout waiting state (step S605), and the winning determination process is terminated.

  If the sub-step process is in a winning determination waiting state (step S601; No), the processor 11 determines whether or not the sub-step process is in a payout waiting state (step S606). If the sub-step state is a payout waiting state (step S606; Yes), the processor 11 determines whether or not the payout has been completed (step S607). If the payout is completed (step S607; Yes), the processor 11 shifts the main step process to the bet state (step S608), and ends the winning determination state process. When the sub-step process is not in the payout waiting state (step S606; No), or when the payout is not completed (step S607; No), the processor 11 ends the winning determination state process as it is.

  Next, the interrupt process shown in FIG. 9C will be described. FIG. 15 is an explanatory diagram of the interrupt process shown in FIG. As shown in FIG. 15, in the input process (step S201), the processor 11 first acquires an input (step S701). This includes reading a flag from the integration filter 15 and obtaining an input from the input / output unit 13 (reading a flag). Further, the read flag is reset.

  After step S701, the processor 11 filters the acquired input as necessary (step S702), sets a corresponding flag provided in the register 11a or the memory 12 (step S703), and performs input processing. finish.

  In the interrupt step process (step S202), the processor 11 determines control data indicating the control contents for the stepping motors 64a to 64c (step S801), and determines control data indicating the control contents for the medal reception unit 36 (step S802). And the control data which shows the control content with respect to the medal paying part 37 are determined (step S803), and an interruption step process is complete | finished.

  In the output process (step S203), the processor 11 writes the control data to the flag of the input / output unit 13 (step S901), clears the corresponding flag provided in the register 11a or the memory 12 (step S902), End the output process. The output of the excitation control step for controlling the stepping motor shown in FIG. 5 is also performed by this output processing.

  Next, sensor output and flags will be described. FIG. 16 is an explanatory diagram of sensor outputs and flags. FIG. 16A shows sensor outputs of the reel position detection sensors 65a to 65c. The state where the voltage of the sensor output is “H” is the reel position detection signal.

  The rise and fall of the reel position detection signal is unstable, and noise called chattering occurs. Therefore, if the sensor output is used as it is for the sensor output flag as shown in FIG. 16B, it cannot be specified whether the sensor output flag is “1” or “0” during chattering.

  The sensor output flag is filtered, and the flag indicating a change from “0” to “1” is the up-edge flag. Similarly, the sensor output flag is filtered, and a flag indicating a change from “1” to “0” is a down edge flag. The level flag is a flag indicating the state of the sensor from the up edge flag and the down edge flag.

  An up edge flag is used to detect the reel position detection signal. However, since the sensor output flag is in an indefinite state during chattering, there is a case where the up edge flag does not turn on until chattering ends. In such a case, the detection of the reel position detection signal is delayed, and the initialization of the rotational position management step is delayed.

  However, if the sensor output is acquired every 0.5 milliseconds by the integration filter 15 and the processor 11 reads the flag of the integration filter 15 and uses it as a sensor output flag, as shown in FIG. Since the influence of chattering can be eliminated and the up edge flag can be set early, the rising edge of the reel position detection signal can be detected with high accuracy. For this reason, it is possible to prevent omission of detection.

  Next, a game using a gaming machine will be described. The gaming machine 1 according to the present embodiment has a horizontal winning line E1 at the middle display position of the reel window 30. Further, the processor 11 of the main control board 10 of the gaming machine 1 displays a replay time state (hereinafter referred to as “RT state”) that is a game state in which a re-gamer is won with a higher probability than in a normal game state. Control the transition of multiple game states including. In addition, the sub-control board 20 of the gaming machine 1 switches between an AT state that notifies the pressing order of the stop button, which is advantageous for the player by controlling images and sounds, and a non-AT state that does not notify the pressing order. .

  Further, in the gaming machine 1, as a pressing order that is a reference for operating the stop buttons 33a to 33c in the non-AT state (hereinafter referred to as “reference pressing order”), there is a pressing order for stopping the reel 51a by the first stop operation. Recommended. And, as will be described later, as for the combination of symbols that triggers the transition to the RT state where the re-gamer is won with high probability, a pressing order other than the standard pressing order (hereinafter referred to as “anomalous pressing order”) is input. In this case, the game stops on the winning line E1, so that in the non-AT state where the push order is not notified, the game state other than the RT state is stayed.

  The sub control board 20 performs the ART lottery according to the result of the internal lottery in the processor 11 of the main control board 10. The ART lottery is a process of drawing whether to grant the ART state right. The ART state is a state where the sub control board 20 is in the AT state and the main control board 10 is in the RT state. The state in which the sub control board 20 is in the AT state but the main control board 10 has not shifted to the RT state is referred to as an ART preparation state. Granting ART state rights as a result of the ART lottery is referred to as ART right winning. If the ART right is won, the sub-control board 20 is in the AT state. Since the main control board 10 is not in the RT state at this time, it is in the ART preparation state.

  If the push order small combination is won in the AT state, the sub-control board 20 notifies the correct push order of the push order correct combination. The push order correct answer winning combination is the winning combination having the largest payout among the winning combinations included in the winning push order winning combination.

  Further, if the push order re-game player is won in the ART ready state, the CPU 101 of the sub-control board 20 notifies the correct push order of the push order correct game player. The push order correct answer re-gamer is a re-game player in which combinations of symbols that trigger the transition to the RT state are arranged on the winning line E1 among the re-game players included in the selected push-order re-game player.

  Next, the game state of the main control board 10 will be described. FIG. 17 is an explanatory diagram for describing a game state of the main control board 10. FIG. 17A is an excerpt of the combination used by the gaming machine 1.

  FIG. 17A shows five roles of “8 small roles”, “1 small portion 1”, “1 small portion 2”, “replay 1”, and “special Lip 1”. The symbol combination “bell-bell-bell” is associated with “eight small roles”. Similarly, “one small combination 1” is associated with the symbol combination “A-X”, and “one small combination 2” is associated with the symbol combination “A-B-X”. It is attached. Note that “A”, “B”, and “X” in the symbol combinations correspond to specific symbols, respectively.

  “Replay 1” is associated with the symbol combination “A-Replay 1-A”. Further, the symbol combination “B-replay 2-B” is associated with “special lip 1”. The replay 1 and the special lip 1 are both regame players, but the replay 1 is not used as a trigger for the game state transition, and the special lip 1 is used as a trigger for the game state transition.

  In the following description, the symbol combination associated with one small role 1 is referred to as symbol combination Fc1, and the symbol combination associated with special lip 1 is referred to as symbol combination Fc2.

  FIG. 17B is an explanatory diagram for explaining the transition of the game state of the main control board 10. As shown in FIG. 17B, the game state of the main control board 10 includes a game state G1, which is a normal game state serving as a game reference in the gaming machine 1, and a re-game player having a higher probability than the game state G1. There is a game state G2 which is an RT state to be won.

  The game state G2 is entered when the symbol combination Fc2 stops on the winning line E1. Also, the game state G1 is entered when the symbol combination Fc1 is stopped on the winning line E1.

  The symbol combinations Fc2 are arranged on the winning line E1 when a predetermined irregular pressing order is input. Specifically, as a target of internal lottery by the processor 11, a replaying player used as a trigger for the game state transition as in the special Lip 1 and a replaying player used as a trigger for the game state transition as in the replaying player 1 A push order re-gamer that will be elected simultaneously with the re-gamer will be established. The re-playing role used as a trigger for the game state transition is designated as the correct push order re-playing role, and the re-playing role not used as the game state transition is designated as the push-order incorrect answer re-playing role. The correct answer pressing order and the predetermined irregular pressing order are set as the correct answer pressing order.

  In this way, if the symbol combination Fc2 is aligned on the winning line E1 only when a predetermined irregular pressing order that is a correct answer pressing order is input, if the sub-control board 20 is in the non-AT state, Since the correct pressing order is not notified, the main control board 10 stays in the game state G1. When the sub-control board 20 is in the ART ready state, if the push order re-gamer wins, the correct push order is notified, so that the main control board 10 shifts to the game state G2 (RT state). Become.

  Next, the state of the sub control board 20 will be described. FIG. 18 is an explanatory diagram for explaining the state of the sub-control board 20. As shown in FIG. 18, the state of the sub-control board 20 includes a non-AT state and an AT state. The non-AT state includes a penalty state, an ART lottery low probability state, an ART lottery normal probability state, and an ART lottery high probability state. The AT state includes an ART preparation state and an ART state.

  Of the ART lottery low probability state, the ART lottery normal probability state, and the ART lottery high probability state, the ART lottery low probability state has the lowest lottery probability that the ART right is won by the ART lottery. In the ART lottery high probability state, the lottery probability that the ART right is won by the ART lottery is the highest. In the ART lottery normal probability state, the lottery probability that the ART right is won by the ART lottery is between the ART lottery low probability state and the ART lottery high probability state.

  The ART lottery low probability state, the ART lottery normal probability state, and the ART lottery high probability state can be transferred to each other by the transfer lottery. If the stop button 33a to 33c is operated in a pushing order other than the standard pushing order in any of the ART lottery low probability state, the ART lottery normal probability state, or the ART lottery high probability state, that is, an irregular pushing order, a penalty state Migrate to In the penalty state, since ART lottery is not performed, the ART right is not won. The penalty state ends with a predetermined number of games and becomes an ART lottery low probability state.

  In the ART lottery low probability state, the ART lottery normal probability state, and the ART lottery high probability state, the ART lottery is performed. If the ART right is won as a result of the ART lottery, the state shifts to the ART ready state. In the ART ready state, since the correct pressing order of the pressing order re-gamer is notified, it is possible to align the symbol combination Fc2 on the winning line E1. When the symbol combination Fc2 is aligned with the winning line E1, the main control board 10 shifts to the game state G2. In response to the notification indicating that the main control board 10 has shifted to the game state G2, the sub control board 20 shifts to the ART state. The ART state of the sub-control board 20 ends with a predetermined number of games and becomes an ART lottery high probability state.

  Next, a modified example of the gaming machine 1 will be described. In the above description, the clock signals f1 and f2 are supplied to the processor 11 and the clock signal f3 is supplied to the integration filter 15, and the integration filter 15 acquires the reel position detection signal based on the clock signal f3 and sets the flag. The configuration in which the processor 11 reads the flag of the integration filter 15 based on the clock signal f2 is shown. Such a configuration can be used even in a case where the processing capacity of the processor 11 is low and the number of settable interrupt processes is limited. On the other hand, if a sufficient number of interrupt processes can be set in the processor, the function of the integration filter 15 may be provided in the processor.

  FIG. 19 is a configuration diagram showing an internal configuration of the gaming machine 1 when the processor has the function of the integration filter 15. The main control board 110 shown in FIG. 19 does not have the integration filter 15, and all the clock signals f1 to f3 generated by the clock generation circuit 14 are supplied to the processor 111.

  The processor 111 sequentially executes the main routine of the program based on the timing of the clock signal f1. In addition, the processor 111 executes a first interrupt process based on the timing of the clock signal f2, and executes a second interrupt process based on the timing of the clock signal f3.

  The second interrupt process performs a process of acquiring a predetermined input among the inputs received by the input / output unit 13 based on the clock signal f3 and setting a flag in the register 111a. Specifically, a flag is assigned to each of the reel position detection sensors 65a to 65c, and when the input of the reel position detection signal is read, the corresponding flag is set to ON. The flag is reset by the first interrupt process.

  The first interrupt process includes reading and clearing the flag set in the second interrupt process, obtaining other inputs not assigned to the second interrupt process, and supplying an output signal. Since other configurations and operations are the same as those shown in FIG. 3, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 20 is an explanatory diagram regarding acquisition of input by the processor 111 illustrated in FIG. 19. The processor 111 activates the second interrupt process every 0.5 milliseconds based on the clock signal f3, and acquires inputs from the reel position detection sensors 65a to 65c. At this time, if a reel position detection signal is input from the reel position detection sensors 65a to 65c, the corresponding flag is turned on, that is, set to "1". If no reel position detection signal is input, the flag state is maintained.

  Further, the processor 111 starts the first interrupt process every 1.5 milliseconds based on the clock signal f2, reads the flag set in the second interrupt process, and resets it. Therefore, the second interrupt process is activated three times until the flag is read and reset by the first interrupt process, and inputs from the reel position detection sensors 65a to 65c are acquired. If the reel position detection signal is acquired in any of the three acquisitions, the flag is set to “1”. For this reason, in the first interrupt process, the logical sum of the three acquisition results obtained by the second interrupt process is read.

  As described above, in the gaming machine 1 according to the present embodiment, the output of the reel position detection sensor 65c is acquired at a cycle of 0.5 milliseconds, and the determination of the reel position by the processor 11 is performed at a cycle of 1.5 milliseconds. Therefore, the sensor output can be acquired with high accuracy. For this reason, detection failure of the reel position detection signal can be prevented, initialization delay of the rotation position management step can be prevented, and the reels 51a to 51c can be stopped within a specified time.

  In the above-described embodiment, the symbol number PN = 1 is positioned on the winning line E1 in the middle stage of the reel window 30 at the timing when the reel position detection signal is detected (rotational position management step = 0). Although the case where it arrange | positions was demonstrated, this invention is not limited to this. For example, the symbol may be arranged so that the symbol with the symbol number PN = 7 is positioned on the winning line E1 in the middle stage of the reel window 30 at the timing when the reel position detection signal is detected (rotational position management step = 0). Further, in the state where the reel position detection signal has been detected and 12 steps advanced (rotational position management step = 12), the symbol with the symbol number PN = 1 is positioned on the winning line E1 in the middle stage of the reel window 30. You may arrange.

  In the above-described embodiment, the configuration in which the rotational position management step is incremented every time the excitation control step is incremented has been described as an example. However, every time the excitation control step is incremented, the rotational position management step is set to a predetermined value. You may implement by the structure which adds one by one.

  Further, in the above embodiment, the winning line is only the winning line E1 that is the center of the reel window 30, but the present invention can be applied even to a gaming machine having a plurality of winning lines. Needless to say. A single winning line other than the center of the reel window 30 may be used. Further, in the present embodiment, the state of the main control board 10 is set to one of the game states G1 and G2, but more game states may be included. The game state may include a bonus game state.

  Further, in the AT state in the above-described embodiment, an effect of notifying the pushing order that is advantageous to the player is executed. The symbol may be notified.

  In the above embodiment, a slot machine that uses medals as game media has been described as an example. However, the present invention can also be applied to a revolving game machine called a parrot or a pacilot that uses game balls as game media. Good.

  It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications are possible.

  As described above, the gaming machine according to the present invention is suitable for preventing the specified time from exceeding when the reel is controlled to stop.
