Description

  The present invention relates to a gaming machine represented by a slot machine (pachislot) and a pachinko machine.

  In recent years, in a state where a game has not been performed for a predetermined time (for example, a state in which no game is accepted for 40 seconds from the end of the game), for the purpose of reducing the power consumption of the game table, the motor that is the drive source of the reel is excited It is devised to stop. For example, Patent Document 1 includes a stepping motor having two pairs of excitation phases as a drive source for a reel displaying a plurality of symbols, and all of the stepping motors are subjected to stop control by two-phase excitation for a predetermined time. A motor stop control device that stops the excitation is disclosed.

Japanese Patent Laying-Open No. 2005-52420 (FIG. 11)

  However, due to the characteristics of a stepping motor composed of a rotor having a permanent magnet and a stator (excitation phase) which is an electromagnet, the polarity of the stator disappears when the two-phase excitation is performed and the non-excitation state is established. For this reason, the rotor position does not stay at the time of performing the two-phase excitation, and the rotor rotates to be stationary to one of the two phases. When restarting the rotor, take into account the step-out due to the excitation deviation at the time of excitation (for example, if the excitation position and the rotor position are separated, the magnetic attraction and excitation switching timing do not match and the rotation varies) Then, the two-phase excitation that was performed immediately before the non-excitation state is performed is performed again. However, when the rotor is stationary on the opposite side to the rotation direction, the rotation operation is performed only in the rotation direction. However, when the rotor is stationary on the phase side in the same direction as the rotation direction, the initial fine movement caused by the rotation operation in the normal rotation direction is always performed after the reverse rotation operation for the two-phase excitation is performed once. As a result, there was a concern that the player who resumed the game did not look good at the initial rotational motion.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine that suppresses power consumption and does not impair the appearance of the initial operation of the movable member to which the stepping motor is connected.

  In order to achieve the above object, a game machine according to the present invention is configured as follows.

  The game table according to the present invention includes, as one aspect thereof, a movable member that is movable in relation to the game, a rotor to which the movable member is coupled, and a plurality of phases to which a pulsed excitation current is supplied. Stepping motor, rotation control means for controlling rotation of the stepping motor by switching the phase for supplying the excitation current and the flow direction of the excitation current, and without switching the flow direction of the excitation current for two phases A stop control means for controlling the stop of the stepping motor while maintaining the state for supplying the excitation current; and a determination means for determining whether or not a predetermined condition for stopping the supply of the excitation current is satisfied. When the determination means determines that the predetermined condition is satisfied, one of two phases to which an excitation current is supplied by the stop control means. A non-excitation control means for stopping the supply of the excitation current to the other phase after stopping the supply of the excitation current to the phase, and the rotation control means, when resuming the rotation control of the stepping motor Based on the excitation current supply stop order of the non-excitation control means, the rotation control of the stepping motor is performed so that the initial rotation direction of the rotor is a predetermined direction. .

  In one aspect of the present invention, even if the stepping motor is de-energized, the rotation starts smoothly without initial fine movement, so that the initial operation of the movable member to which the stepping motor is connected is reduced while suppressing power consumption. There is no loss.

  The rotation control means controls the rotation of the rotor along the predetermined one direction, and the supply of the excitation current to the one phase advances the rotation of the rotor in the predetermined one direction. Preferably, the supply of the excitation current to the other phase is control that advances the rotation of the rotor in the direction opposite to the predetermined one direction. In this case, since the excitation of the phase on the reverse rotation direction side is released after the excitation of the phase on the rotation direction side is canceled with respect to the stop-controlled phase, the rotor must be stopped on the opposite side to the rotation direction without fail. Can do.

  In addition, when the rotation control unit resumes the rotation control of the stepping motor, the same phase as the excitation current phase supplied by the stop control unit and the flow direction of the excitation current supplied by the stop control unit It is preferable to supply the exciting current in the same flow direction. In this case, the same excitation pattern can be applied both when the stepping motor is de-energized and when it is not de-energized, so the capacity of control data can be reduced and the development man-hours can be reduced. be able to.

  Further, it further comprises a time measuring means for measuring the time during which the stop control is performed by the stop control means, the determination means determines whether or not the time measured by the time measuring means is a threshold value or more, It is preferable to determine that the predetermined condition is satisfied when the time measured by the time measuring means is equal to or greater than a threshold value. In this case, useless power consumption spent while the game is not being performed can be eliminated. Moreover, even if the excitation of the stepping motor is resumed, the appearance of the initial operation of the movable member to which the stepping motor is connected is not impaired.

  Further, the power supply monitoring means for monitoring the power supply voltage status is further provided, and the determination means determines whether or not the power supply voltage status monitored by the power supply monitoring means is equal to or lower than a predetermined threshold value which is a low voltage value. When the power supply voltage monitored by the power supply monitoring unit is equal to or less than a threshold value, it is preferable to determine that the predetermined condition is satisfied. In this case, even if the excitation of the stepping motor is resumed when the power is restored, the appearance of the initial operation of the movable member to which the stepping motor is connected is not impaired.

  In addition, when supplying the excitation current as the stop control, the stop control means performs stop control to supply the excitation current in a predetermined flow direction to specific two phases, and performs the rotation control. When performing the first rotation control after the power is turned on, the means preferably performs rotation control for starting supply of excitation current in the predetermined flow direction for the two specific phases. . In this case, stop control is performed with two specific fixed phases, and excitation is started from the two specific fixed phases when the power is turned on, so the stepping motor is connected even if the RAM is cleared. The appearance of the initial operation of the movable member is not impaired.

  The movable member includes a plurality of reels having a plurality of types of symbols, and the reels have the same outer circumference and have the same rotation axis. It is preferable that the stop control is a stop control in which symbols applied to each reel are arranged in a straight line in the reel arrangement direction. In this case, it is possible to give a sense of unity to the operation of the plurality of reels when the reels are stopped or when the rotation is started.

  According to the present invention, it is possible to provide a game machine that suppresses power consumption and does not impair the appearance of the initial operation of the movable member to which the stepping motor is connected.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Reel motor control circuit>
Next, the configuration of the reel motor control circuit 302 described above will be specifically described with reference to FIGS. 10 to 15 show examples of circuit diagrams of the reel motor control circuit 302. FIG.

  As shown in FIG. 10, the address signal (specifically, A0 to A15) output from the ROM / RAM built-in one-chip CPU 301 is sent to the address decoding circuit 350 via the address bus 303 as shown in FIG. Is output. A signal SG50 (specifically, XWR, XRD, XIORQ) output from the ROM / RAM built-in one-chip CPU 301 is a signal for controlling reading and writing of data, and is output to the address decoding circuit 350. As a result, as one of the signals, a chip select signal SG10 (specifically, XOCS_05, XOCS_06, XOCS_07) used for reel control is input from the address decoding circuit 350 to the output interface 370 as shown in FIG. Is done.

  As shown in FIGS. 10 and 12, data signals (specifically, D0 to D7) output from the ROM / RAM built-in one-chip CPU 301 are output via a data bus 305 on the data output side. 370 is input. As a result, as shown in FIG. 12, the reel signal SG20 for controlling the reels 110 to 112 (specifically, the signal SG20L for controlling the left reel 110 (specifically, LA Phase, LB Phase, L-AI0, L- AI1, L-BI0, L-BI1), signal SG20C for controlling the middle reel 111 (specifically, CA Phase, CB Phase, C-AI0, C-AI1, C-BI0, C-BI1), right reel 112, signals SG20R (specifically, RA Phase, RB Phase, R-AI0, R-AI1, R-BI0, R-BI1) are respectively supplied to the reel motor drive unit 330 (specifically, the left reel Motor drive unit 330a, middle reel motor drive unit 330b, and right reel motor drive unit 330c).

  FIG. 13 shows a circuit configuration of a left reel driving unit 330a that drives the left reel 110, and a stepping motor 720 driven by the left reel driving unit 330a. The middle reel 111 and the right reel 112 have the same configuration. Specifically, the left reel driving unit 330a includes two motor drivers 306A and 306B. That is, the rotation of the stepping motor 720 is controlled using two motor drivers per reel. Here, the motor driver 306 (the motor drivers 306a and 306b are motor drivers having the same function, and therefore the function of the motor driver will be described as the motor driver 306) for driving the stepping motor 720. The motor current is controlled in accordance with the reel control signal SG20L output from the CPU 310.

  The stepping motor 720 is a bipolar stepping motor as described above, and is driven and controlled by 1-2 phase excitation based on the reel control signal SG20L. Specifically, the stepping motor 720 is composed of a magnet (rotor) 721 fixed to a rotating shaft and a wound coil (stator) 723 attached to the outer side of the stepping motor 720, and a magnetic force is generated by current flowing through the coil portion. It is generated (excited), and the rotor 721 is attracted to rotate by a certain angle. That is, there is a predetermined order when a current is passed through the stator 723. In the present embodiment, current control is performed based on 1-2 phase excitation.

  FIG. 14A is a specific circuit diagram of the motor driver 306, and FIG. 14B is a table showing the current level of the motor current. In FIG. 14A, I0 and I1 are logic inputs, and the magnitude of the motor current is controlled by a combination of signals I0 and I1 as shown in FIG. 14B. As shown in FIG. 14B, the controllable levels are H level 100%, M level 60%, L level 20%, and zero current 0%. Phase controls the direction of the motor current. Further, MA and MB are motor outputs. When Phase is an H level signal, current flows from MA to MB, and when Phase is an L level signal, current flows from MB to MA. Yes. The motor driver 306 used in this embodiment is usually used for microstep control of a stepping motor. The micro step control is a control for further stopping at a plurality of stop positions within one step of the stepping motor, and this control is realized by changing the balance of the current flowing through each phase. For example, if the value of the current passed through each exciting coil is the same, it can be stopped in the middle of one step. If the value of the current passed through one excitation coil increases, the stop position moves in the direction of that excitation coil. In this way, the stop position can be set at an arbitrary position within one step. In the present embodiment, the drive current is controlled by using a current variable function used for microstep control.

  As shown in FIGS. 10 and 15, as part of input signals from various sensors, an input signal SG30 (specifically, a left reel index input signal REEL_INDEX_L, a middle reel index input signal REEL_INDEX_C, As for the right reel index input signal REEL_INDEX_R), the detection signal SG40 is input to the ROM / RAM built-in one-chip CPU 301 via the input interface 361.

<Stepping motor>
Next, how to move the stepping motor 720 of the slot machine 100 of this embodiment will be described. The stepping motor 720 of this embodiment is a motor having a resolution of 252 steps per rotation and driven by the 1-2 phase excitation method. That is, one rotation can be controlled with 504 pulses.

  FIG. 16 shows the rotation control data for controlling the rotation of the stepping motor 720 and the excitation phase at that time, and more specifically, the rotation control data, the reel control signal SG20 output from the CPU 310, and each motor at that time. The relationship with the motor current which flows into a coil is shown. As shown in FIG. 16, the rotation control data is roughly divided into non-excitation data that does not excite the stepping motor 720 and excitation data that excites the stepping motor 720. The excitation data further includes weak excitation that performs weak excitation rotation. Data (also referred to as rotation control data A) and strong excitation data (also referred to as rotation control data B) for performing strong excitation rotation. Here, weak excitation rotation (also referred to as rotation state A) refers to a rotation state when the magnitude of the motor current is 20% as shown in FIG. 14B, and strong excitation rotation (rotation state B). (Also referred to as ")" refers to the rotational state when the magnitude of the motor current is 100% as shown in FIG. That is, in the present embodiment, by accurately controlling two types of currents (strong current and weak current) flowing through the stepping motor 220, the load on the stepping motor 720 is reduced, and powerful acceleration and deceleration are performed as well as accurate. To stop. In the table of FIG. 16, + and-of the motor current value indicate the direction of current flow, which means that current flows from the + terminal to the-terminal.

  Further, in the rotation states A and B, the reel is rotated by sequentially and repeatedly executing eight patterns (combinations of elements of the reel control signal SG20) for each drive pulse. For example, in the rotation state A, “A1 (phases to be controlled are A phase and B phase: hereinafter, excitation phase is referred to as AB phase) → A2 (phase to be controlled is A phase: hereinafter, excitation phase is referred to as A phase) ) → A3 (phases to be controlled are A phase and B-phase: hereinafter, excitation phase is referred to as AB-phase) → A4 (phase to be controlled is B-phase: hereinafter, excitation phase is referred to as B-phase) → A5 (The controlled phases are A-phase and B-phase: the excitation phase is hereinafter referred to as AB-phase) → A6 (the controlled phase is A-phase: the excitation phase is hereinafter referred to as A-phase) → A7 (The controlled phase is B phase and A-phase: the excitation phase is hereinafter referred to as BA-phase) → A8 (the controlled phase is B phase: the excitation phase is hereinafter referred to as B phase) → A1 (AB phase) → A8 (A phase) → ... ”is repeated in sequence to execute weak excitation rotation, and the reel moves in a certain direction (in this embodiment, Pattern is to rotate in a direction) which moves from top to bottom. Similarly, in the rotation state B, “B1 (AB phase) → B2 (A phase) → B3 (AB-phase) → B4 (B-phase) → B5 (A-B-phase) → B6 (A-phase) ) → B7 (BA-phase) → B8 (B-phase) → B1 (AB-phase) → B2 (A-phase) →. It will rotate in the direction (in this embodiment, the direction in which the symbol moves from top to bottom).

  More specifically, each pattern, that is, the combination of each element of the reel control signal SG20 is stored as rotation control data in the ROM 312, and the CPU 310 sequentially instructs the rotation control data to the motor drivers 306a and 306b as pulse signals. As a result, a motor current flows through the motor coil of the stepping motor 720, and the stepping motor 720 is driven to rotate.

  FIG. 17 is an example showing the transition of the rotation control data described above together with the operation of the reel. In the present embodiment, in order to reduce power consumption of the slot machine 100, if the game is not performed for a predetermined time (for example, 40 seconds from the end of the game), the stepping motor 720 of the stopped reel is set in a non-excited state. It has become. Therefore, as shown in FIG. 17, when the start operation by the start lever 135 is performed when the reel control state is “under non-excitation control”, the CPU 310 changes the reel control state from “under non-excitation control” to “ Update to “acceleration control in progress” and switch to rotation control data B, which is rotation control data for strong excitation rotation, and the rotation control data B is sequentially updated. In this embodiment, as shown in FIG. 17, when the reel control state is “acceleration control”, rotation control data B-1 is interrupted for 4 interrupt times, and then rotation control data B-2 is interrupted for 3 interrupts. Time, then rotation control data B-3 is 2 interrupt times, rotation control data B-4 is 2 interrupt times, rotation control data B-5 is 1 interrupt time, The rotation control data B-6 is executed for one interruption time, and the reels are accelerated by gradually decreasing the set time of the rotation control data B set sequentially.

  Next, when the rotation speed of the reel reaches 80 rpm (Revolution Per Minute), the CPU 310 updates the reel control state from “acceleration control in progress” to “during constant speed control” in order to keep the rotation speed constant. The control data B is switched to the rotation control data A, and the rotation control data A is sequentially updated at each interrupt time. In the present embodiment, as shown in FIG. 17, when the reel control state is “during constant speed control”, the rotation control data A-7 is set to 1 interrupt time, and then the rotation control data A-8 is set to 10%. After executing the loading time, the rotation of the reels is set to a constant speed by repeating a pattern in which each of the rotation control data A-1 to A-8 is sequentially executed by one interruption time.

  Next, when a stop operation is performed with the stop button, the CPU 310 updates the reel control state from “during constant speed control” to “during pull-in control”, and switches the rotation control data A to the rotation control data B. The rotation control data B is sequentially updated at each interrupt time until the stop position. In this embodiment, as shown in FIG. 17, when the reel control state is “during pull-in control”, the remaining rotation control data B during constant speed control is executed for each interrupt time, and then the number of pull-in frames During the interruption time corresponding to the above, the pattern in which each of the rotation control data B-1 to B-8 is sequentially executed by one interruption time is repeated. FIG. 17 shows an example in which the number of frames to be drawn is 0. Since the rotation control data during constant speed control ends with the rotation control data A-2, the rotation control data B-3- Each of B8 is sequentially executed by one interruption time.

  Next, when the reel comes to the stop position, the CPU 310 updates the reel control state from “during pull-in control” to “during brake control”, and maintains the same rotation control data B for several interruption times. Stop the reel. In the present embodiment, as shown in FIG. 17, when the reel control state is “during brake control”, rotation control data B-1 is executed for 4 interrupt times.

  Thereafter, the CPU 310 updates the reel control state from “braking control” to “stop control”, switches the rotation control data B to the rotation control data A, and waits for a predetermined time (in this embodiment) after the reel stops. The same rotation control data A is maintained until 40 seconds) or until a start operation by the start lever 135 is performed. In the present embodiment, the rotation control data A-1 is continuously executed as shown in FIG.

  When a predetermined time (40 seconds in the present embodiment) has elapsed since the reel stopped, the CPU 310 updates the reel control state from “stop control” to “reverse excitation control”, and no excitation is performed. In order to stop the rotor 721 of the stepping motor 720 at a position where the reel does not reversely rotate in the initial operation, the same rotation control data B is executed for several interruption times. In this embodiment, as shown in FIGS. 16 and 17, when the reel rotates, it is excited from the AB phase (starting from the rotation control data B-1), so that the reel control state is in reverse excitation control. Is excited in the B phase (rotation control data B-8). As a result, the rotor 721 stops at the B-phase position in the non-excited state. Therefore, when the rotor 721 is restarted, the reverse rotation of the rotor 721 does not occur in the initial operation. That is, in the present embodiment, as shown in FIG. 17, when the reel control state is “during reverse excitation control”, the rotation control data B-8 is executed for 3 interruption times.

  Thereafter, the CPU 310 updates the reel control state from “during reverse excitation control” to “during non-excitation control”, and releases the excitation of the stepping motor 720.

  As described above, in this embodiment, the reel control state is in the non-excitation control → acceleration control → constant speed control → retraction control → brake control → stop control → reverse excitation control → non-excitation control The rotation of the reel of the slot machine 100 is controlled by selecting rotation control data corresponding to each reel control state.

  Of course, if the condition for de-energizing the reel is not satisfied, the reel control state is as follows: during stop control → during acceleration control → during constant speed control → during pull-in control → during brake control → during stop control And change. Also in this case, even if the reel control state is updated from “stop control” to “acceleration control”, the rotation control data A-1 is updated to the rotation control data B-1, so that the player feels uncomfortable. The reel can be rotated without giving. That is, the rotation control data during the acceleration control of the present embodiment is the rotation control that does not give the player a sense of incongruity even when the rotation starts from the non-excitation state or when the rotation starts from the stop control. It is data.

  As described above, in the present embodiment, when the reel is stopped, the rotor 721 of the stepping motor 720 is stopped at the fixed two-phase (AB phase), and then when the excitation is resumed, Since no excitation is performed after stopping at a fixed one phase (B phase) that does not reversely rotate, when excitation is resumed from two fixed phases (AB phase), the normal operation is performed after reverse rotation in the initial operation of the rotor 721. There is no such thing as rotating in the direction of rotation. That is, once the stepping motor 720 is in a non-excited state, the appearance of the initial rotation operation of the reel does not deteriorate.

  The stepping motor 720 described above is a stepping motor for rotating the reels 110 to 112. However, in this embodiment, the stepping motor 244 is also used to operate the horizontal movable member 204 in the same manner. . Hereinafter, how to move the stepping motor 244 will be described.

  FIG. 18 is a table showing excitation patterns of drive control data (data corresponding to rotation control data) for operating the horizontal movable member 204. The drive control states of the stepping motor 244 connected to the horizontal movable member 204 include “acceleration control”, “constant speed control”, “brake control”, “stop control”, and “reverse excitation control”. , And “Non-excitation control in progress” exist, and drive control data corresponding to each drive control state is patterned and stored on the ROM 612. That is, in this embodiment, the slot machine realizes a non-excitation state in which excitation is released not only to the stepping motor 720 connected to the reel but also to the stepping motor 244 connected to the horizontal movable member 204. 100 power consumption is suppressed.

  Since the horizontal movable member 204 can move in the left-right direction, the stepping motor 244 has both positive and negative rotation directions. In this embodiment, the case where the horizontal movable member 204 moves in the A direction shown in FIG. 5A is defined as a positive rotation direction, and the case where the horizontal movable member 204 moves in the B direction is defined as a negative rotation direction. To do. Further, in the present embodiment, the origin position of the horizontal movable member 204 is the left end, and in the initial movement of the horizontal movable member 204 when power is restored and after non-excitation, the position is temporarily changed from the currently stopped position to the origin position. After returning, it moves to the center position and stops.

  Here, the non-excitation flag shown in FIG. 18 is flag information indicating whether or not the drive control state of the stepping motor 244 has become a non-excitation state. When the non-excitation flag is ON, the drive control state is It shows that the stepping motor 244 is subjected to acceleration control (including subsequent constant speed control) after the non-excitation state is reached. In the present embodiment, as described above, in the initial operation after the drive control state becomes the non-excitation state, the horizontal movable member 204 once returns to the origin position. Only when the direction of rotation is negative. Therefore, when the rotation direction is negative, excitation patterns of different drive control data are prepared according to the non-excitation flag.

  The excitation phase of the drive control data shown in FIG. 18 corresponds to the excitation phase of the rotation control data with the same sign shown in FIG. 16. For example, the drive control data B-1 indicates that the stepping motor 244 is in the AB phase. Energize.

  For example, when operation data having pattern data NO of 1 is selected, first, drive control data B-1 is 4 interrupt times, then drive control data B-2 is 3 interrupt times, and then drive control is performed. The data B-3 is executed for 2 interrupt times, and then the drive control data B-4 is executed for 1 interrupt time to accelerate the horizontal movable member 204 in the A direction. Similarly, when the non-excitation flag is OFF and the operation data whose pattern data NO is 2 is selected, first, the drive control data B-1 is set to 4 interrupt times, and then the drive control data B-8 is set to 3 The horizontal movable member 204 is accelerated in the B direction by executing the interrupt time, then the drive control data B-7 for 2 interrupt times, and then the drive control data B-6 for 1 interrupt time.

  As in the case of the reel, the drive control data A-1 is maintained and executed when the drive control state is in the stop control, and no excitation is performed when the drive control state is in the reverse excitation control. In the initial operation, the drive control data B-8 is executed for three interruption times to stop the rotor at a position where the horizontal movable member 204 does not reversely move (specifically, movement in the A direction). As a result, when the movement is resumed after the non-excitation, the drive control data B-7 is started (pattern data NO is 2, the non-excitation flag is ON), so that the initial appearance of the horizontal movable member 204 does not look good. Absent.

  As described above, in the present embodiment, when a predetermined condition is satisfied, there is no stepping motor connected to a movable member (for example, the reels 110 to 112, the horizontal movable member 204, etc.) movable in relation to the game. Excitation is used to save power in the slot machine 100, and even if the stepping motor is not excited, control is performed without impairing the appearance of the initial operations of the reels 110 to 112 and the horizontal movable member 204 connected to the stepping motor. Yes.

<Operation>
Next, the operation of the slot machine 100 including the above stepping motors 220 and 244 will be described.

<Power-on processing>
First, a power-on process executed by the CPU 310 of the main control unit 300 when the slot machine 100 is turned on will be described with reference to FIG. This figure is a flowchart showing the flow of power-on processing.

  When the power switch of the slot machine 100 is turned on, the CPU 310 of the main control unit 300 executes a power-on process described below. If the reel control state was under de-energized control when the power was turned off, when the power is turned on, the reel control state is set to de-energized control, and the reel control state is not changed until the reel actually starts rotating. Maintained during excitation control.

  In step S101, various initial processes (initialization processes) are performed.

  In step S102, it is determined whether or not at least a part of the RAM 313 is abnormal. If there is an abnormality in the RAM 313, the process proceeds to step S103, and if there is no abnormality, the process proceeds to step S104. Various methods for detecting an abnormality in the RAM 313 are conceivable. For example, the same information is stored in the two first storage areas and the second recording area, and after the power is turned on, the first storage area is stored. As an example, a method of comparing the stored information with the information stored in the second storage area and determining that the two are different from each other is an example.

  In step S103, RAM error processing is performed. In this RAM error processing, preparation is made to clear the storage areas of all the RAMs 313 except the used stack area, preparation for sending an error occurrence command to the sub-control unit 400, or the like.

  In step S104, it is determined whether or not a setting key switch (not shown) is in an ON state. If the setting key switch is in the ON state, the process proceeds to step S105, and if it is in the OFF state, the process proceeds to step S106.

  In step S105, a setting value change process is performed. The set value changing process is a process of setting lottery data regarding the internal lottery of the winning combination. Here, the set value adjusts the ratio of the total number of game media paid out by the game table to the total number of game media used for the game table as the number of bets by the player when playing the game for a predetermined period. For example, setting values in a plurality of stages, for example, setting “1” to setting “6” can be set.

  In step S106, it is determined whether forced RAM clear is in an ON state. Specifically, the forced RAM clear is turned on based on the power being turned on and the reset button of the reset switch being pressed for a long time (for example, pressing for 5 seconds). When the forced RAM clear is in the ON state, the process proceeds to step S107. When the forced RAM clear is in the OFF state, the process proceeds to step S109.

  In step S107, an initial state game start process is performed. In this initial state game start processing, “setting value storage area” and “storage area excluding stack area used when clearing RAM 313” are cleared, automatic settlement and presence / absence setting are set, whether internal winning is set, A control command is transmitted to the sub control unit 400.

  In step S108, game execution processing (details will be described later) is performed.

  In step S109, the slot thin 100 is restored to the state before the power is shut off by the restoration process, and the game execution process described later is resumed.

<Game execution processing>
Next, the game execution process will be described with reference to FIG. This figure is a flowchart showing in detail the flow of the game execution process in step S108 of FIG. CPU 310 repeatedly executes the game execution process described below unless it detects a power-off or the like.

  In step S201, processing related to medal insertion is performed. Here, it is checked whether or not medals have been inserted, and the winning line display lamp 120 is turned on according to the number of medals inserted. It is not necessary to insert medals when winning the re-gamer in the previous game.

  At this time, in the timer interrupt process of the main control unit 300, a medal insertion command is transmitted to the sub control unit 400 so that the sub control unit 400 recognizes the medal insertion. The sub-control unit 400 performs an effect for generating a medal insertion sound based on the medal insertion command.

  In step S201, a process related to a game start operation is performed. Here, it is checked whether or not the start lever 135 has been operated. If it is determined that the start lever 135 has been operated, the number of medals used in the game is determined.

  At this time, in the timer interrupt process of the main control unit 300, a start lever reception command is transmitted to the sub control unit 400. When the sub-control unit 400 is on standby based on the start lever reception command, the sub-control unit 400 performs an effect of generating a weight sound or the like.

  In step S202, an effective winning line is determined according to the number of medals determined in step S201.

  In step S203, the random number generated by the random number generation circuit 317 is acquired based on the start operation.

  In step S204, an internal lottery of a winning combination is performed using the random number acquired in step S203 and the winning combination lottery table stored in the ROM 312. As a result of the internal lottery, when any winning combination is won internally, the flag of the winning combination is turned on internally. In step S204, an internal lottery result command indicating the result of the internal lottery is transmitted to the sub-control unit 400. The sub-control unit 400 receives the internal lottery result command, grasps the result of the internal lottery, and executes an effect corresponding to the result of the internal lottery.

  In step S205, based on the internal lottery result in step S204, the reel stop control data is selected with reference to a plurality of stop position data selection tables defined for each of the reels 110 to 112.

  In step S206, a reel rotation start process for starting rotation of all the reels 110 to 112 is executed based on the start operation. Further, in the timer interrupt process of the main control unit 300, a reel rotation start command is transmitted to the sub control unit 400 so that the sub control unit 400 recognizes the start of rotation of all reels. The sub-control unit 400 starts an effect at each control unit based on the reel rotation start command. The reel rotation start process will be described later in detail.

  In step S207, it is determined whether all reels have stopped based on the reel rotation control process of the timer interrupt process. If all the reels are stopped, the process proceeds to step S208. If not, the process returns to step S207.

  In step S208, the winning determination of the symbols stopped when the stop buttons 137 to 139 are pressed is performed. Here, it is determined that the winning combination is won when the winning symbol combination corresponding to the winning combination that has been won internally or the winning combination having the flag carried over is arranged (displayed) on the activated winning line. For example, if “replay-replay-replay” is arranged on the activated pay line, it is determined that the replay is won. In step S208, a display determination result command indicating the result of winning determination and the type of winning combination is transmitted to the sub-control unit 400. By receiving the display determination result command, the sub-control unit 400 grasps the result of the winning determination and the type of the winning combination, and executes an effect corresponding to the display determination result command.

  In step S209, if any winning combination with payout is won, the number of medals corresponding to the winning combination is paid out.

  In step S210, game state control processing is performed. In this game state control process, control for changing the game state is performed. For example, in the case of a BB (Big Bonus) winning, a BB (Big Bonus) game is prepared from the next time, and in those final games, Prepare to start normal games next time.

  As described above, one game is completed, and thereafter, the game progresses as the CPU 310 repeats the game execution process.

<Reel rotation start processing>
FIG. 21 is a flowchart showing in detail the flow of the reel rotation start process in step S206 of FIG.

  In step S301, a gaming time monitoring timer value is acquired. In step S302, it is determined whether or not the acquired gaming time monitoring timer value has exceeded 4.1 seconds. When the game time monitoring timer value has passed 4.1 seconds or more, the next game may be started, and the process proceeds to step S303. On the other hand, when the game time monitoring timer value has not passed 4.1 seconds, step S302 is repeated.

  In step S303, the game time monitoring timer value is reset, and then in step S304, a reel rotation start command to be transmitted to the sub-control unit 400 is set.

  In step S305, the reel state of the left reel 110 is set to “rotation state”.

  In step S306, the reel state of the middle reel 111 is set to “rotation state”.

  In step S307, the reel state of the right reel 112 is set to “rotation state”.

  In step S308, the reel control state is set to “acceleration control in progress”. Further, the acceleration start request flag is set to ON.

<Timer interrupt processing>
Next, timer interrupt processing executed by the CPU 310 of the main control unit 300 will be described with reference to FIG. FIG. 22 is a flowchart showing the flow of timer interrupt processing. The main control unit 300 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 1.504 ms), and executes timer interrupt processing triggered by this timer interrupt.

  In step S401, the CPU 310 saves each register value.

  In step S402, a power supply voltage monitoring process for monitoring the power supply voltage is performed.

  In step S403, based on the power supply voltage monitoring process, it is determined whether or not the power-off flag is ON. If the power-off flag is ON, the process proceeds to step S407. If the power-off flag is OFF, the process proceeds to step S404. The power-off flag in this embodiment is set to ON in a power-off interrupt process (not shown). This power-off interrupt process is assigned to the NMI (non-maskable interrupt) of the CPU 310. When the power supply voltage of the slot machine 100 becomes lower than a predetermined voltage value, a non-maskable interrupt is generated and the power-off flag is set to ON. It has become. Note that the power-off detection method is not limited to this. For example, a method of monitoring the voltage value at a predetermined time interval (so-called polling) can be considered in addition to the method of detecting the power-off by interruption.

  In step S404, the value of each register saved in step S401 is restored.

  In step S405, a reel rotation control process for controlling the rotation of the reel is executed. The reel rotation control process in step S405 will be described later in detail.

  In step S406, another interrupt process is executed. For example, the motor driving of a hopper for paying out medals, acceptance of medal insertion, panel lamp update, output of output port data, transmission of commands prepared in each process, and the like are performed.

  In step S407, the current stack pointer value is saved in the RAM 313, and the process proceeds to step S408.

  In step S408, data in a specific area (setting values in this embodiment) in the RAM 313 is saved in three setting value storage areas, and data in other areas (for example, game information) is saved in the saving area. .

  In step S409, rotation control data corresponding to the reel control state during reverse excitation control is acquired for each of the left reel 110, the middle reel 111, and the right reel 112. Next, in step S410, the left reel 110, middle reel, and the like. After setting the rotation control data corresponding to the acquired reverse excitation control for each of the reel 111 and the right reel 112, a standby state (infinite loop) is entered in preparation for power-off. That is, when the power is cut off, the stepping motor 720 to which the reels 110 to 112 are connected is in a non-excited state, so that the reel control state is reversed in preparation for the start of excitation of the stepping motor 720 after the next power-on. After the excitation state, it is set to the non-excitation state. As a result, when the excitation of the stepping motor 720 is started after the next power-on (when the reel control state is under acceleration control), the reels 110 to 112 do not reversely rotate in the initial operation, and the normal rotation is smoothly performed. Can rotate in the direction.

<Reel rotation control processing>
Next, the reel rotation control process will be described in detail with reference to FIG. FIG. 23 is a flowchart showing in detail the flow of the reel rotation control process in step S405 of FIG.

  In step S501, it is determined whether the operation of the stop button is valid. This is to determine that the operation of the stop button is valid if the stop button valid information set in the “constant speed process” in the “reel control determination process” in step S505 described later is ON. It is. When the stop button is valid, the process proceeds to step S502 to perform stop button reception processing, and then the processing of steps S503 to S510 is performed for each of the left reel 110, the middle reel 111, and the right reel 112. The stop button reception process will be described later in detail. On the other hand, when the stop button is not valid, the processes of steps S503 to S510 are performed for the left reel 110, the middle reel 111, and the right reel 112, respectively.

  In step S503, reel control information is acquired. Here, the reel control information means the entire information for controlling the reel, and includes information on the reel state and information on the reel control state.

  In step S504, it is determined whether or not the reel control state of the acquired reel control information is “during rotation control”. Specifically, if the reel control state is any of acceleration control, constant speed control, pull-in control, or brake control, it is determined that rotation control is being performed. When the reel control state is “during rotation control”, the process proceeds to step S505. Otherwise, the process proceeds to step S506.

  In step S505, a reel control determination process is performed to determine reel control based on information on the reel control state. Here, the reel control determination processing is shown in more detail in the flowchart shown in FIG. 24, and will be described with reference to FIG.

The reel control determination process is a process for sequentially switching the reel rotation control in accordance with the progress of the game. Specifically, in accordance with the game start operation of the player, an acceleration process for starting the rotation of the reel to accelerate the reel and a constant speed process for maintaining the speed after accelerating the reel to a certain rotation speed are performed. . With the subsequent stop operation of the player, a drawing control process for maintaining the rotation of the reel from the symbol position of the reel when the stop operation is performed to the symbol stop position displayed on the reel display window as a game result, and the symbol stop position The brake control process for maintaining the stop state for a certain time is sequentially performed.

  In step S601, information regarding the reel control state is acquired.

  In step S602, it is determined whether or not the acquired reel control state is “during stop control”. If the acquired reel control state is “during stop control”, the reel is stopped. The control determination process ends. On the other hand, if the acquired reel control state is not “stop control in progress”, the process proceeds to S603.

  In step S603, it is determined whether or not the acquired reel control state is “acceleration control in progress”. When the reel control state is “acceleration control in progress”, the process proceeds to step S604, and acceleration processing (processing for accelerating the rotation of the reel; details will be described later) is performed. On the other hand, when the reel control state is not “acceleration control in progress”, the process proceeds to step S605.

  In step S605, it is determined whether or not the acquired reel control state is “during constant speed control”. When the reel control state is “during constant speed control”, the process proceeds to step S606, and constant speed processing (processing for maintaining the rotation of the reel at a constant speed; details will be described later) is performed. On the other hand, when the reel control state is not “during constant speed control”, the process proceeds to step S607.

  In step S607, it is determined whether or not the acquired reel control state is “during brake control”. When the reel control state is “brake control in progress”, the process proceeds to step S608, and a brake control process (a process for stopping the rotation of the reel; details will be described later) is performed. On the other hand, when the reel control state is not “braking control”, the process proceeds to step S609.

  In step S609, since the reel control state is “during pull-in control”, a pull-in control process (a process for controlling the pull-in of the reel to the stop position; details will be described later) is performed.

  Returning to FIG. 23, in step S506, it is determined whether or not the reel control state is “during non-excitation control”. If the reel control state is not “non-excitation control”, the process proceeds to step S507. If the reel control state is non-excitation control, the process proceeds after step S510.

  In step S507, after performing reverse excitation control on the stopped reel, a reel stop control process (details will be described later) for releasing the excitation is performed.

  In step S508, rotation control data suitable for each reel control state described above is acquired. Specifically, as shown in FIG. 17, rotation control data suitable for the reel control state is selected.

  In step S509, the rotation control data acquired in step S508 is set.

  In step S510, the reel control information is updated because the content of the reel control information has been changed in accordance with the processing described above.

<Acceleration processing>
FIG. 25 is a flowchart showing in detail the acceleration process in step S604 of FIG.

  In step S701, it is determined whether there is an acceleration start request. When the acceleration start request flag is ON, it is determined that there is an acceleration start request, the process proceeds to step S702, an initial value is set in the acceleration counter offset, and the acceleration start request flag is set OFF (that is, 1). Step S702 is executed only in the second acceleration process). This acceleration start request flag is set to ON in step S308 of the reel rotation start process shown in FIG. In step S703, an initial value corresponding to the set acceleration counter offset value is acquired and set in the acceleration counter.

  Here, the initial value set in the acceleration counter offset means the number of rotation control data patterns set in the reel control state during acceleration control. This is also the number of patterns from the start of reel rotation until reaching a constant rotation speed, which is set in advance. For example, in the example shown in FIG. 17, since the rotation control data B-1 to B-6 are set, “6” is preset as an initial value.

  The initial value set in the acceleration counter means an interruption time (number of drive pulses) for maintaining the set rotation control data B. This is a counter that controls the time for gradually increasing the update speed of the rotation control pattern in order to prevent the stepping motor from stepping out due to sudden rotation of the reel at a constant speed. The acceleration counter is set in advance corresponding to the acceleration counter offset. In the example shown in FIG. 17, the acceleration counter offset values are “6”, “5”, “4”, “3”, “2”, “1”, and the acceleration counters are “4”, “3”, “2”, “1”, respectively. 2 ”,“ 1 ”and“ 1 ”are set. For example, when the value of the acceleration counter offset is 6, that is, when the set rotation control data is the rotation control data B-1, the rotation control data B-1 is maintained for 4 interruption times. Thereafter, the value of the acceleration counter is decremented in steps of 3 → 2 → 1 → 1 → 1 and finally becomes an interrupt time, that is, a rotation control pattern update cycle during constant speed control.

  If there is no acceleration start request in step S701, the process proceeds to step S704, the acceleration counter value is decremented by 1 and updated, and then the process proceeds to step S705 to set the reel drive signal switching request flag to OFF. Here, the reel drive signal switching request flag is a flag for determining whether to switch to the next rotation control data or to maintain the rotation control data set last time in the rotation control data acquisition in step S508 of FIG. When the reel drive signal switching request flag is OFF, the rotation control data set last time is maintained.

  In step S706, it is determined whether or not the acceleration counter value is zero. When the acceleration counter value is 0, it is necessary to switch the rotation control data. Therefore, the process proceeds to step S707, the reel drive signal switching request flag is set to ON, and then the process proceeds to step S708, where the acceleration counter offset value is set. 1 is subtracted and updated. On the other hand, when the acceleration counter value is not 0, the acceleration process is terminated.

  In step S709, it is determined whether or not the acceleration counter offset value is zero. When the acceleration counter offset is 0, “acceleration control is in progress” is completed, and thus the process proceeds to step S710, where the reel control state is changed from “acceleration control in progress” to “constant speed control in progress” and set. On the other hand, when the acceleration counter offset value is not 0, the process proceeds to step S703, and an initial value corresponding to the updated acceleration counter offset value is set in the acceleration counter.

<Constant speed processing>
FIG. 26 is a flowchart showing in detail the constant speed process in step S606 of FIG. The constant speed process mainly performs a process of tracking the symbol position of the reel. In order for the main controller 300 to grasp the symbol position of the reel, the symbol position is monitored using two counters, a “symbol number counter” and a “symbol interval counter”. Here, before describing the constant speed processing, first, the “symbol number counter” and the “symbol interval counter” will be described.

  FIG. 27 is a diagram showing the relationship between the symbol number counter and the symbol interval counter. The symbol number counter is a counter for storing and holding a symbol located in the middle stage of the reel display window 113, which is a reference position. For example, for the left reel 110, the chance symbol at the upper end of the symbol row of the left reel 110 is the reference symbol. The count starts when the index sensor 325a passes the light shielding piece 750. Each symbol is associated with the count value in advance, and the main control unit 300 can determine the symbol that is stopped and displayed on the reel display window 113 from the symbol number counter value when the reel is stopped, and perform a winning determination. it can. The symbol interval counter is the number of drive pulses per symbol (number of timer interrupt processing), and is 24 (total number of 504 drive pulses). The main control unit 300 sets the number of driving pulses per symbol in the symbol interval counter, and subtracts each time the driving pulse is output, so that the symbol number counter is updated by 1 when the symbol interval counter value becomes zero. I have to.

  In step S801, the symbol interval counter value is decremented by 1 and updated.

  In step S802, it is determined whether or not the symbol interval counter value is zero. When the symbol interval counter value is 0, since the next symbol is substituted, the process proceeds to step S803, the symbol number counter value is decremented by 1 and updated, and then the process proceeds to step S804, where the symbol interval counter has an initial value of 24. Set. On the other hand, when the symbol interval counter value is not 0, the process proceeds to step S805.

  In step S805, the detection result of the index sensor 325 is acquired. Here, the detection result of the index sensor 325 is detected when the passage of the light shielding piece 750 provided at the position where the symbol number counter value is 0 and the symbol interval counter value is 0 is detected.

  In step S806, it is determined whether or not the index sensor 325 has been detected. When the index sensor 325 is detected, the symbol position of the reel has been searched, so the process proceeds to step S807, the stop button valid information is set to ON, and then the process proceeds to step S808, where the symbol number counter is set to 0, 24 is set in the symbol interval counter and the constant speed process is terminated. On the other hand, when the index sensor 325 is not detected, the constant speed process is terminated.

<Retraction control processing>
FIG. 28 is a flowchart showing in detail the pull-in control process in step S609 of FIG. Here, the pull-in control processing is to realize stop control according to the result of the internal lottery, and when stopping the reel, the reel is moved from the symbol position where the stop button is operated to a predetermined number of frames (this embodiment In the case of 0 to 4 frames), it is a process of sliding and stopping. As a result, the winning combination that was won internally by the internal lottery or the so-called flag carry-over winning combination is allowed to be displayed together with the corresponding symbol combination. The symbol combinations corresponding to are not displayed together.

  In step S901, 1 is subtracted from the value of the pull-in counter. Here, in the pull-in counter, an interrupt time required for pull-in control is set as an initial value in a pull-in counter setting process described later. For example, in the example shown in FIG. 17, the initial value set in the pull-in counter is 6 (number of drive pulses, interrupt time).

  In step S902, it is determined whether or not the value of the pull-in counter is zero. When the value of the pull-in counter is 0, the pull-in control has been completed, so the process proceeds to step S903, the initial value is set in the braking counter, and then the process proceeds to step S905, where the reel control state is changed from “during pull-in control”. Change to "Brake Control" and set. Here, an interruption time required for brake control is set as an initial value in the braking counter. For example, in the example shown in FIG. 17, the value set in the braking counter is 4 (number of drive pulses, interrupt time). On the other hand, if the value of the pull-in counter is not 0 in step S902, the pull-in control process is terminated.

<Brake control processing>
FIG. 29 is a flowchart showing in detail the brake control process in step S608 of FIG.

  In step S1001, 1 is subtracted from the value of the braking counter.

  In step S1002, it is determined whether or not the value of the braking counter is zero. When the value of the braking counter is 0, the braking is completed, so the process proceeds to step S1003, and the reel control state is changed from “during brake control” to “during stop control” and set. On the other hand, when the value of the braking counter is not 0, the brake control process is terminated.

<Stop button reception process>
FIG. 30 is a flowchart showing in detail the stop button reception process in step S502 of FIG. Note that the stop button reception process is executed in the reel rotation control process of FIG. 23 after the stop button valid information is set to ON in the state where the stop button can be received, that is, in the constant speed process shown in FIG. It is what is done. The stop button reception process is a process of determining a position where the reel is stopped based on the operation of the stop button.

  In step S1101, stop acceptance information is acquired. Here, the stop reception information is a part of the reel control information, and means all information necessary for determination of stop reception.

  In step S1102, a stoppable reel is determined from the acquired stop acceptance information and set as stoppable reel information (for example, when the left reel 110 is determined to be a stoppable reel, a left reel is set. To do).

  In step S1103, it is determined whether or not a reel stop button corresponding to the set stoppable reel information has been received. When the stop button is received, the process proceeds to step S1104 to acquire data relating to the reel to be stopped (stop target reel data), and then proceeds to step S1105 to perform a pull-in counter setting process (details will be described later). Do. Here, the reel data to be stopped is specifically data related to the stop position of the reel. Next, in step S1106, in the series of stop button receiving processes described above, the reel control information is updated because the information regarding the reel stop is changed among the reel control information. On the other hand, if no stop button has been received, the process proceeds to step S1107.

  In step S1107, the stoppable reel information is cleared. This is because the reel that can be stopped is changed by the pull-in counter setting process in step S1105 (for example, when the pull-in counter setting process is performed on the stopable left reel, the left reel can be stopped). Not a reel).

  In step S1108, the stop button LED information is updated. This is to update the LED information of the stop button according to whether or not each reel can be stopped. As an example, blue is set for a stopable reel and the stop button is pressed. , Red is set.

<Retraction counter setting process>
FIG. 31 is a flowchart for explaining in detail the pull-in counter setting process in step S1105 of FIG.

  In step S1201, the value of the symbol number counter is acquired, and the position where the stop operation is performed is detected.

  In step S1202, the number of drawn frames is acquired from the selected reel stop control data based on the position where the stop operation has been performed.

  In step S1203, the number of remaining interrupts is acquired with reference to the excitation table. Specifically, the number of interruption times from the previous rotation control data (last rotation control data during constant speed control) to B-8 data is acquired. For example, in the pull-in control shown in FIG. 17, the number is 6 from B-3 to B-8.

  In step S1204, a pull-in counter value is calculated from the acquired number of pull-in frames and the remaining number of interrupts, and the calculated pull-in counter value is set in the pull-in counter. Specifically, a value obtained by multiplying the number of drawn frames by 24 and adding the remaining interrupt number is set in the drawing counter. For example, in the pull-in control shown in FIG. 17, since the number of pull-in frames is 0, 6 is set in the pull-in counter.

  In step S1205, the reel control state is changed from “during constant speed control” to “during pull-in control” and set.

<Control processing during reel stop>
Next, the reel stop control process will be described in detail with reference to FIG. FIG. 32 is a flowchart showing in detail the reel stop control process in step S507 of FIG.

  In step S1301, it is determined whether or not the re-gamer is operating, that is, whether or not the re-gamer is won in the game. When the re-gamer is in operation, the reel control state is not set to the non-excitation control, so the reel stop control process is terminated. If the re-game player is not operating, the process proceeds to step S1302.

  In step S1302, it is determined whether or not the reel control state is “during reverse excitation control”. If the reel control state is under reverse excitation control, the process proceeds to step S1308. If the reel control state is not under reverse excitation control, the process proceeds to step S1303.

  In step S1303, the first counter is updated. Here, the first counter is a counter that measures the time from when the reel control state is under stop control, and is incremented by 1 for each interrupt time. The initial value is 1.

  In step S1304, it is determined whether the value of the first counter is greater than a threshold value. Here, the threshold value is specifically 27000, which is an interruption time (1.504 ms × 27000) corresponding to 40 s. In the present embodiment, the demonstration effect is executed when 40 s has elapsed since the reel control state was under stop control, and accordingly, the stepping motors of the reels 110 to 112 are executed accordingly. 720 is not excited. If the value of the first counter is larger than the threshold value, the process proceeds to step S1306. If the value of the first counter is equal to or smaller than the threshold value, the process proceeds to step S1305.

  In step S1305, it is determined whether or not the settlement button 134 has been received. When the settlement button 134 is received, a demonstration effect is executed, and thus the process proceeds to step S1306. Otherwise, the reel stop control process is terminated.

  In step S1306, the reel control state is set to reverse excitation control. That is, in the present embodiment, when the value of the first counter is larger than the threshold value or when the settlement button 134 is operated, the reel control state that was under stop control is set to reverse excitation control. .

  In step S1307, a command indicating that the reel control state is in reverse excitation control (hereinafter referred to as reverse excitation control command) is prepared for transmission to the sub-control unit 400. Note that the reverse excitation control command is transmitted to the sub-control unit 600 via the sub-control units 400 and 500.

  In step S1308, the second counter is updated. Here, the second counter is a counter for measuring the time for performing reverse excitation control. In the present embodiment, specifically, reverse excitation control is performed for 3 interruption times.

  In step S1309, it is determined whether the second counter is greater than 3. If the second counter is greater than 3, the process proceeds to step S1310. If the second counter is 3 or less, the reel stop control process is terminated.

  In step S1310, since the time for performing reverse excitation control has elapsed, the reel control state is set to non-excitation control.

<Sub-control unit 400 main process>
Next, the main process in the sub control unit 400 will be described with reference to FIG. This figure is a flowchart showing the flow of the main process of the sub-control unit 400. The main process of the sub-control unit 400 is performed mainly by the CPU 410 of the sub-control unit 400, and the processes in steps S1402 to S1407 are repeatedly executed unless a power-off is detected.

  In step S1601 of the strobe interrupt process, the command output from the main control unit 300 is stored in the command storage area provided in the RAM 413 as an unprocessed command.

<Sub-control unit 400 timer interrupt processing>
Next, timer interrupt processing of the sub-control unit 400 will be described with reference to FIG. The sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (in this embodiment, once every 2 ms), and executes the sub-control unit 400 timer interrupt process in response to this timer interrupt. The sub-control unit 400 sets a general-purpose timer (10 ms), and the general-purpose timer is updated in step S1701.

<Sub-control unit 500 main processing>
Next, the main process of the sub control unit 500 will be described with reference to FIG. This figure is a flowchart of the main process of the sub-control unit 500.

  In step S1801, initialization processing is executed. In this initialization process, recovery processing when the power is cut off, initial setting of the input / output ports, initialization of the storage area in the RAM, data load processing, and the like are performed. In addition, a command from the sub-control unit 400 can be received. Furthermore, other initialization processes such as variable initialization are performed.

  In step S1802, command input processing of the sub-control unit 500 is performed. In this sub control unit 500 command input process, it is determined whether or not there is an unprocessed command in the command storage area of the RAM 513. If there is an unprocessed command, the process corresponding to the unprocessed command is executed.

  In step S1803, the effect data of the sub control unit 500 is updated. In the effect data update process, the operation control data for controlling the effect is updated.

  In step S1804, if there is data to be output to the driver of the liquid crystal display device 157 in the effect data updated in step S1803, liquid crystal effect processing is performed.

  In step S1805, it is determined whether there is a control command to be transmitted to the sub-control unit 600 in the effect data updated in step S1803. If applicable, the process proceeds to step S1806; otherwise, the process returns to step S1802.

  In step S1806, a control command is transmitted to the sub-control unit 600, and the process returns to S1802.

<Sub-control unit 500 timer interrupt processing>

  In step S1901, it is determined whether there is a control command received from the sub-control unit 400. If there is a control command received from the sub-control unit 400, the process proceeds to step S1902, and if there is no control command received from the sub-control unit 400, the sub-control unit 500 timer interrupt process is terminated.

  In step S1902, the command output from the sub control unit 400 is stored as an unprocessed command in a command storage area provided in the RAM 513.

<Sub-control unit 600 main processing>
Next, the main process of the sub-control unit 600 will be described with reference to FIG. This figure is a flowchart of the main process of the sub-control unit 600.

  In step S2001, initialization processing is executed. In this initialization process, recovery processing when the power is cut off, initial setting of the input / output ports, initialization of the storage area in the RAM, data load processing, and the like are performed. In addition, a command from the sub-control unit 500 can be received. Furthermore, other initialization processes such as variable initialization are performed. For example, the horizontal movable member 204 of the effect unit 220 is controlled to move to the center position and stop after performing movement control to return to the origin in the initialization process after turning on the power.

  In step S2002, it is determined whether or not at least one control command is stored in the command storage area. If applicable, the process proceeds to step S2003; otherwise, the process returns to S2002.

  In step S2003, one control command is acquired from the command storage area, and the acquired control command is determined. The acquired control command is deleted from the command storage area.

  In step S2004, it is determined whether the acquired control command (control command received from the sub-control unit 500) is a reverse excitation control command. If the acquired control command is a reverse excitation control command, the process proceeds to step S2005. If the acquired control command is not a reverse excitation control command, the process proceeds to step S2006.

  In step S2005, the reverse excitation flag is set to ON. Here, the reverse excitation flag is a flag for determining whether or not the drive control state is set during reverse excitation control. When the reverse excitation flag is ON, the drive control state is set during reverse excitation control. Set. That is, when the stepping motor 720 connected to the reels 110 to 112 is brought into the non-excited state in the main control unit 300, the stepping motor 244 connected to the horizontal movable member 204 is also put into the non-excited state in the sub-control unit 600. Is.

  In step S2006, it is determined whether or not the acquired control command (control command received from the sub-control unit 500) is an operation command for operating the horizontal movable member 204. If the acquired control command is an operation command, the process proceeds to step S2007. If the acquired control command is not an operation command, the process proceeds to step S2009.

  In step S2007, the drive control state is set to “during acceleration control”.

  In step S2008, an operation data update process for updating operation data for operating the horizontal movable member 204 is performed.

  In step S2009, it is determined whether there is a control command to be transmitted to the sub-control unit 400. If there is a control command to be transmitted to the sub-control unit 400, the process proceeds to step S2010, and if there is no control command to be transmitted to the sub-control unit 400, the process returns to step S2002.

  In step S2010, a control command is transmitted to the sub-control unit 400.

<Sub-control unit 600 interrupt processing>
Next, timer interrupt processing of the sub-control unit 600 will be described with reference to FIG. This figure is a flowchart showing the flow of the sub-control unit 600 timer interrupt process.

  In step S2101, it is determined whether there is a control command received from the sub-control unit 500. If there is a control command received from the sub-control unit 500, the process proceeds to step S2102. If there is no control command received from the sub-control unit 500, the sub-control unit 600 timer interrupt process is terminated.

  In step S2102, the command output from the sub-control unit 500 is stored as an unprocessed command in a command storage area provided in the RAM 613.

<Interval timer interrupt processing>
Next, the interval timer interrupt process of the sub control unit 600 will be described with reference to FIG. This figure is a flowchart showing the flow of the sub-control unit 600 interval timer interrupt process. The sub-control unit 600 executes an interval timer interrupt process at a predetermined cycle (in this embodiment, once every 0.3 ms).

  In step S2201, it is determined whether the drive control state is drive control. Specifically, the drive control state being drive control means that the vehicle is under acceleration control, constant speed control, or brake control. When the drive control state is under drive control, the process proceeds to step S2202, and when the drive control state is not under drive control, the process proceeds to step S2203.

  In step S2202, a drive control determination process for determining control of the horizontal movable member 204 based on information related to the drive control state is performed. The drive control determination process is a process of sequentially switching the drive control of the horizontal movable member 204 according to the effect state. Specifically, an acceleration control process for accelerating the horizontal movable member 204, a constant speed process for maintaining a constant speed, and a brake control process for maintaining a stop state at a stop position for a predetermined time are sequentially performed.

  In step S2203, it is determined whether the drive control state is under non-excitation control. If the drive control state is under non-excitation control, the interval timer interrupt process is terminated, and if the drive control state is not under non-excitation control, the process proceeds to step S2204.

  In step S2204, after the reverse horizontal excitation control is performed on the horizontal movable member 204 that is stopped, a control process during driving stop (to be described in detail later) for releasing the excitation is performed.

  In step S2205, drive control data suitable for each of the drive control states described above is acquired. Specifically, as shown in FIG. 18, the drive control data corresponding to the drive control state and the non-excitation flag is selected. As a result, when the non-excitation flag is ON, rotation control that does not reversely rotate the stepping motor 244 is possible in the initial operation during acceleration. If the non-excitation flag is ON, the non-excitation flag is changed to OFF.

  In step S2206, the drive control data acquired in step S2205 is set.

<Control processing during drive stop>
FIG. 37 is a flowchart showing in detail the flow of the control process during drive stop in step S2204 of FIG.

  In step S2301, it is determined whether or not the reverse excitation flag is ON. If the reverse excitation flag is ON, the process proceeds to step S2302, and if the reverse excitation flag is OFF, the control process during driving stop is terminated.

  In step S2302, the drive control state during stop control is changed and set during reverse excitation control.

  In step S2303, the reverse excitation counter is updated. Here, the reverse excitation counter is a counter for measuring time for performing reverse excitation control. In the present embodiment, specifically, reverse excitation control is performed for 3 interruption times.

  In step S2304, it is determined whether the value of the reverse excitation counter is greater than 3. If the value of the reverse excitation counter is greater than 3, the process proceeds to step S2305. If the value of the reverse excitation counter is 3 or less, the drive stop control process is terminated.

  In step S2305, since the reverse excitation control process is completed, the reverse excitation flag is set to OFF.

  In step S2306, the drive control state during reverse excitation control is changed to non-excitation control and set.

  In step S2307, since the drive control state is now under non-excitation control, the non-excitation flag is set to ON.

  As described above, according to the slot machine 100 of the present embodiment, when the reel is stopped, the rotor 721 of the stepping motor 720 is stopped at two fixed phases (AB phase), and then is not excited. First, since the rotor 721 is stopped in a fixed one phase (B phase) that does not reversely rotate when excitation is resumed, no excitation is performed. Therefore, when the excitation is restarted from two fixed phases (AB phase), the rotor 721 In the initial operation, there is no such thing as rotating in the normal rotation direction after reverse rotation.

  Further, according to the slot machine 100 of the present embodiment, similarly, the same control is performed for the motor 244 connected to the horizontal movable member 204. Therefore, even if the motor 244 is de-energized, the initial operation of the rotor is performed. There is no reverse rotation.

  As a result, according to the present embodiment, it is possible to provide a game table that suppresses power consumption and does not impair the appearance of the initial operation of the movable member that is movable in relation to the game.

  In the present embodiment, even when the power is cut off, the reel control state is set to the non-excitation after the reverse excitation control is performed, so the first change after the setting is changed (the setting change is performed after the power is cut off). Even when the reel is rotating, it is not known that the setting has been changed from the initial operation of the reel. In the conventional slot machine, if the reel control state is stopped when the power is turned off, the reel is excited immediately so that the reel control state is stopped when the power is turned on. When the change process is performed, the reel in-control information is also cleared, and the reel is in a non-excited state until the reel actually starts to rotate. As a result, it is attracted to one of the excitation phases by the excitation at the time of reel rotation, which causes a fine operation. Therefore, there is a concern that the player may be notified that the setting has been changed by this fine operation. In other words, in the past, when the setting was changed, the reel rotated slightly backward in the initial operation at the time of the first reel rotation, so that the player was able to grasp that the setting was changed. In the form, there is a special effect peculiar to the game stand that such a thing does not occur.

  In the present embodiment, the stepping motor connected to the reels 110 to 112 and the horizontal movable member 204 has been described as an example. However, the same control is performed on the stepping motor connected to other movable members. Of course, you can do it. For example, the same control may be performed on the vertical movable member 202.

  In the present embodiment, the stepping motor connected to the reels 110 to 112 and the horizontal movable member 204 is a bipolar stepping motor, but may be a unipolar stepping motor.

  Further, in the present embodiment, the rotor of the stepping motor is stopped at the fixed two phases (AB phase), but the present invention is not limited to this, and it is not necessary to stop at the fixed excitation phase. For example, it may be stopped at a predetermined one phase (not fixed). However, in this case, the stopped excitation phase is memorized, and when the rotor is re-excited after non-excitation, refer to the memorized excitation phase and perform excitation from the excitation phase that does not reversely rotate. To do. Thereby, there can exist the same effect as this embodiment.

  Further, in the present embodiment, the present invention is applied to the stepping motor connected to the movable member that is movable in relation to the game of the slot machine, but the present invention is not limited to this, and a pachinko machine, etc. The present invention can also be applied to a stepping motor used for other game machines.

  For example, the game stand according to the present invention is shown in FIG. 38, “a launching device for launching a ball into a predetermined game area, a winning opening configured to be able to enter a ball launched from the launching device, and a winning opening. A detection means for detecting a ball that has entered the ball, a payout means for paying out a ball when the detection means detects a ball, and a variable display device for variably displaying a predetermined symbol (identification information). The pachinko machine 1000 "may be used in which a variable display device displays a stop after changing a symbol and notifies a game state transition when a ball enters and wins.

  In this case, a stepping motor that drives a movable effect member of the pachinko machine 1000 (for example, a rotating variable display device that variably displays a symbol by rotating a reel), a launching device that launches a pachinko ball, or a pachinko machine. The excitation control of the present invention may be applied to a stepping motor that drives a dispensing device that dispenses a ball.

  As mentioned above, although embodiment of this invention has been described, all forms have a special effect peculiar to a gaming machine.
