When the sensor 121 is interposed between the light projecting portion and the light receiving portion (that is, when the optical path of the first detection sensor 121 is shielded by the first detection piece 118), the first detection sensor 121 is ON. When the initial position of the movable accessory 110 is detected and the second detection piece 119 is interposed between the light projecting portion and the light receiving portion of the second detection sensor 122 (that is, the second detection sensor 122 When the optical path is shielded by the second detection piece 119), the second detection sensor 122 is turned ON so that the final position of the movable accessory 110 is detected. The detection signals (on / off signals) of the detection sensors 121 and 122 are transmitted to the effect control board 2000, and the movable accessory 110 is at the initial position or the final position on the effect control board 2000 side. It is determined whether or not it exists.

(3-2. Control of stepping motor)
Next, the stepping motor 160 that is a drive source of the movable accessory 110 will be described with reference to FIGS. First, the basic structure of the stepping motor 160 will be described. Here, FIG. 7A is a conceptual diagram of the stepping motor 160. The stepping motor 160 is a two-phase unipolar stepping motor having stator coils L0, L1, L2, and L3 that form A-phase, B-phase, A ^- phase, and B ^- phase magnetic fields. The rotor (rotor) 161 is attached, and a stator (stator) 162 fixed to the outside thereof. Corresponding stator coils L0 to L3 are wound around each stator 162. When an exciting current is passed through the stator coils L0 to L3 to generate a magnetic force, the rotor 161 is attracted to rotate by a certain angle.

Next, the excitation method of the stepping motor 160 in this embodiment will be described with reference to FIG. In this embodiment, the 2-2 phase excitation method is targeted as the excitation method of the stepping motor 160 (however, other excitation methods such as the 1-1 phase excitation method and the 1-2 phase excitation method may be adopted. ). Here, FIG. 7B is a table for explaining an outline of the excitation sequence of the 2-2 excitation method. In this 2-2 excitation method, the pulse width of each phase is set to twice the width of the 1-1 phase excitation method, and excitation is performed simultaneously while shifting by 1 pulse from the next phase. , A phase / B ^- phase → A phase / B phase → B phase / A ^- phase → A ^- phase / B ^- phase → A phase / B ^- phase → ... (in the case of reverse rotation CCW) Reverse sequence). This excitation method has an advantage that the rotation is stable and a large torque can be obtained as compared with the one-phase excitation. Note that the stepping motor 160 of this embodiment is configured to rotate once by a 120-step drive pulse signal, and the angle change based on the 1-step drive pulse signal is 3 °.

FIG. 8 is a circuit configuration diagram showing a control system for controlling the driving of the stepping motor 160. In the present embodiment, the CPU 2001 of the effect control board 2000 functions as a motor control unit 2010 that generates a two-phase excitation type drive pulse signal of the stepping motor 160 and outputs the drive pulse signal to each excitation phase. The drive pulse signal to the stepping motor 160 is generated based on the excitation data having 4 bits of φA, φB, φA ⁻ , and φB ⁻ as one unit along the excitation sequence of the two-phase excitation system. This excitation data is stored as a data table in the ROM 2002 of the effect control board 2000, and is H level (= 1) for energizing the stator coils L0 to L3 and L level (= 0) for not energizing the stator coils L0 to L3. And a combination. As shown in FIG. 7B, the motor control unit 2010 uses “φA, φB, φA ⁻ , φB ⁻ ” = “1001” when the stepping motor 160 is operated in the normal rotation direction CW as 4-bit excitation data. ”,“ 1100 ”,“ 0110 ”,“ 0011 ”... Are sequentially acquired and“ φA, φB, φA ⁻ , φB ⁻ ”=“ 0011 ”“ 0110 ”“ 1100 ”“ 1001 ”. Obtain sequentially. An excitation phase for the stepping motor 160 is determined by the excitation data, and an excitation current is supplied to the excitation phase.

  In addition, the motor control unit 2010 includes an effect operation pattern that defines the operation content of the movable accessory 110 (stepping motor 160), step number information obtained by counting the number of pulses of the drive pulse signal as the step number, status information of the stepping motor 160, and the like. Referring to FIG. 5, the condition that “the stepping motor 160 is energized ON” and “the operation of the movable accessory 110 is not being held (held)” (also referred to as “voltage switching condition” in the following description) is established. When this occurs, a voltage switching ON signal (L level) is output to the motor drive circuit 2020 (in the following description, the situation where the voltage switching ON signal is output is also referred to as “voltage switching ON”). On the other hand, motor control unit 2010 outputs a voltage switching OFF signal (H level) to motor drive circuit 2020 when the voltage switching condition is not satisfied. In the present embodiment, the time when the voltage switching condition is satisfied corresponds to the case where the movable accessory 110 is moving up and down as the effect operation.

  The motor drive circuit 2020 includes a drive IC 2030 and a supply voltage control circuit 2040. The drive pulse signal from the motor control unit 2010 is input to the input terminals A1, A2, A3, and A4 of the drive IC 2030 and the gate terminals of the switching elements FET11, 21, 31, and 41 of the supply voltage control circuit 2040, respectively. The ON / OFF signal is input to the input terminal G1 of the drive IC 2030.

The drive IC 2030 includes a NOR gate 2031 that receives a voltage switching ON / OFF signal and a ground signal as two inputs, an output from the NOR gate 2031, and drive pulse signals (φA, φB, φA ⁻ , φB ⁻ from the motor control unit 2010. And a three-state buffer 2032 having two inputs. In the drive IC 2030, the drive pulse signal from the motor drive unit 2010 is input to the input terminals A1 to A4, the voltage switching ON / OFF signal from the motor drive unit 2010 is input to the input terminal G1, and the input terminal G2 is grounded. Has been. The output terminals Y1, Y2, Y3, and Y4 are connected to the gate terminals of the switching elements FET12, FET22, FET32, and FET42 of the supply voltage control circuit 2040, respectively. The output from the three-state buffer 2032 is the drive pulse signal (H) input to the input terminals A1 to A4 in accordance with the output signal from the NOR gate 2031 (in response to the input signals input to the input terminals G1 and G2). Level or L level signal) is output as it is from the output terminals Y1 to Y4, and the state in which the three-state buffer 2032 is in a high impedance state and the signal is not output from the output terminals Y1 to Y4.

  FIG. 9 is a function table of the drive IC 2030. L indicates a low level, H indicates a high level, and Z indicates a high impedance. As described above, since the input terminal G2 is grounded, the input of the input terminal G2 is always at the L level. Therefore, when the voltage switching ON signal (L level) is input to the input terminal G1, the output of the NOR gate 2031 becomes an H level signal. Therefore, when an H level signal (driving pulse signal) is input to the input terminals A1 to A4, outputs from the output terminals Y1 to Y4 become H level signals, while an L level signal (driving pulse) is input to the input terminals A1 to A4. When the signal) is input, the output of the output terminals Y1 to Y4 becomes an L level signal (that is, the output is enabled when both of the input terminals G1 and G2 are at the L level). On the other hand, when the voltage switching OFF signal (H level) is input to the input terminal G1, the output of the NOR gate 2031 becomes an L level signal. Therefore, even if a drive pulse signal (L level, H level) is input to the input terminals A1 to A4, the inside of the 3-state buffer 2032 is in a high impedance state, and output from the output terminals Y1 to Y4 is disabled.

  The supply voltage control circuit 2040 includes eight switching elements FET (first switching elements FET11, FET21, FET31, FET41, second switching elements FET12, FET22, and the like) for controlling energization of the stator coils L0 to L3 of the stepping motor 160. FET 32, FET 42), and an N-channel MOSFET is employed in this embodiment. In the first switching elements FET11, FET21, FET31, and FET41, the motor control unit 2010 is connected to the gate terminal (Gate), the source terminal (Source) is grounded, and the drain coil (Drain) is connected to the stator coils L0 to L0 of the stepping motor 160. One end of L3 is connected via the first power supply line. On the other hand, in the second switching elements FET12, FET22, FET32, and FET42, the output terminals Y1 to Y4 of the drive IC 2020 are connected to the gate terminal (Gate), the source terminal (Source) is grounded, and the stepping motor is connected to the drain terminal (Drain). One end of 160 stator coils L0 to L3 is connected via a second power supply line. The other ends of the stator coils L0 to L3 of the stepping motor 160 are connected to a sub control system power supply (16V) in the sub control board 2000.

  The switching element FET receives a drive pulse signal (H level) from the motor control unit 2010 while the drive pulse signal (H level) is input directly or from the motor control unit 2010 via the drive IC 2030. Only when the voltage exceeding the threshold value is applied to the gate terminal, and the current flows between the drain and the source. As a result, the stator coils L1 to L3 of the stepping motor 160 are turned on. Is supplied with an exciting current. Here, resistors R11, R21, R31, and R41 (for example, resistance value = 10Ω) are connected to the first power supply line connecting the stator coils L0 to L3 and the source terminals of the first switching elements FET11, FET21, FET31, and FET41. Are connected to each other, and when the switching elements FET11, FET21, FET31, and FET41 are turned on and a current flows between the drain and the source, 12 V of the first driving voltage is supplied to the stator coils L0 to L3 ( For example, the resistance value on the stepping motor 160 side = 30Ω). On the other hand, since no resistance is connected to the second power line connecting the stator coils L0 to L3 and the source terminals of the second switching elements FET12, FET22, FET32, and FET42, the switching elements FET12, FET22, and FET32 are not connected. When the FET 42 is turned on and a current flows between the drain and the source, the stator coil L0 to L3 is supplied with 16V of the second drive voltage (16V substantially the same as the sub control system power supply).

  In the motor drive circuit 2020 having such a configuration, a case where a drive pulse signal (H level) and a voltage switching ON signal (L level) for exciting the A phase (stator coil L0) are input from the motor control unit 2010 will be considered. At this time, both the switching elements FET11 and 12 in the supply voltage control circuit 2040 are turned on. In this state, a current flows only between the drain and source of the second switching element FET12 having a lower impedance, and the first drive voltage 16V of the second drive voltage higher than 12V is supplied to the stator coil L0.

On the other hand, consider a case where a drive pulse signal (H level) and a voltage switching OFF signal (H level) for exciting the A phase (stator coil L0) are input from the motor control unit 2010. At this time, the first switching element FET11 is turned on and the second switching element FET12 is turned off. In this state, a current flows only between the drain and source of the first switching element FET11, and the first driving voltage 12V Is supplied to the stator coil L0. Here, the case of exciting the A phase has been described as a representative, but the same applies to the cases of the other B phase, A ^- phase, and B ^- phase. When a drive pulse signal (L level) is output from the motor control unit 2010, a voltage exceeding a threshold value is not applied to the gate terminal, so that the switching element FET is turned OFF, and the voltage switching ON / OFF signal is related. The coil stators L0 to L3 are not supplied with a driving voltage and are in a non-excited state.

  Here, when the operation contents of the motor drive circuit 2020 are summarized, a voltage switching ON signal (L level) is output from the motor control unit 2010 to the motor drive circuit 2020 in conjunction with the output of the drive pulse signal (H level). Then, 16V of the second drive voltage is supplied to the stator coils L0 to L3. On the other hand, when a voltage switching OFF signal (H level) is output from the motor control unit 2010 to the motor drive circuit 2020 in conjunction with the output of the drive pulse signal (H level), 12V of the first drive voltage is set to the stator coil L0. To L3.

(3-3. Operating mode of movable accessory)
Next, the operation | movement aspect of the movable accessory 110 is demonstrated. The operation mode of the movable accessory 110 is roughly divided into an initial operation and a production operation. The initial operation (also referred to as “initialization operation”) is an operation mode that is executed only once when the pachinko gaming machine PM is turned on. In order to control the rendering operation of the movable accessory 110 by the stepping motor 160. The first detection sensor 121 and the second detection sensor 122 are normally turned on / off by operating the stepping motor 160 and moving the movable accessory 110 up and down. It is confirmed whether or not it is turned off (this is also referred to as “sensor confirmation operation”). On the other hand, the rendering operation is executed for the purpose of exerting the rendering effect by operating / stopping in conjunction with the change display and stop display of the symbol variation by the rendering display device 70 on the assumption that the initial motion is performed. Is done. The production operation includes an error return operation for eliminating the error and returning the movable accessory 110 to the initial position when an abnormality such as step-out occurs in the stepping motor 160.

  In the following, the outline of the initial operation and the rendering operation of the movable accessory 110 will be described in order with additional reference to FIGS. Here, FIG. 10 is a schematic diagram for explaining the contents of the rendering operation of the movable accessory 110, FIG. 11 is a schematic diagram for explaining an initial motion based on the initial motion pattern A, and FIG. 12 is an initial motion pattern B. FIG. 13 is a schematic diagram for explaining the rendering operation based on the rendering operation pattern C (basic motion pattern).

<Initial operation>
The initial operation of the movable accessory 110 is executed according to a predetermined initial operation pattern. In this initial operation, different operations are executed according to the current position of the movable accessory at the start of the initial operation, that is, depending on whether or not the movable accessory 110 is present at the initial position.

  First, when the movable accessory 110 does not exist at the initial position when the power is turned on, an initial operation based on the initial operation pattern A is executed. In this initial operation, as shown in FIG. 11, (A1) the movable combination 110 is lowered to the detection position of the first detection sensor 121, (A2) the detection signal of the first detection sensor 121 is confirmed, (A3) the movable combination The object 110 is raised to the detection position of the second detection sensor 122, (A4) the detection signal of the second detection sensor 122 is confirmed, (A5) the movable accessory 110 is lowered to the detection position of the first detection sensor 121, (A6) The operation is completed by executing the detection signals of the first detection sensor 121 in the order of confirmation.

  Here, in the operation of (A1) → (A2), even if the movable accessory 110 is lowered by 159 steps between the first detection sensor 121 and the second detection sensor 122, the first detection sensor 121 causes the movable accessory 110 to move down. An error occurs when the initial position of is not detected. When the confirmation operation of the first detection sensor 121 causes an error continuously for a predetermined number of times (three times in this example), the operation process is stopped. In the operation of (A3) → (A4), even if the movable accessory 110 is raised by 159 steps between the first detection sensor 121 and the second detection sensor 122, the second detection sensor 122 causes the movable accessory 110 to move. An error occurs when the final position is not detected. When the confirmation operation of the second detection sensor 122 causes an error continuously for a predetermined number of times (three times in this example), the operation process is stopped. Further, in the operation of (A5) → (A6), even if the movable accessory 110 is lowered by 159 steps between the first detection sensor 121 and the second detection sensor 122, the first detection sensor 121 causes the movable accessory 110 to move. An error occurs when the initial position is not detected. When the confirmation operation of the first detection sensor 121 causes an error continuously for a predetermined number of times (three times in this example), the operation process is stopped. On the other hand, in the final operation (A6), when the first detection sensor 121 detects that the movable accessory 110 is present at the initial position, the initial operation is normally completed.

  On the other hand, when the movable accessory 110 is in the initial position when the power is turned on, an initial operation based on the initial operation pattern B is executed. In this initial operation, as shown in FIG. 12, (B1) the movable combination 110 is raised to the detection position of the second detection sensor 122, (B2) the detection signal of the second detection sensor 122 is confirmed, (B3) the movable combination The operation is completed when the object 110 is lowered to the detection position of the first detection sensor 121 and (B4) the detection signal of the first detection sensor 121 is confirmed. Similar to the above-described initial operation, the operation process is stopped when the confirmation operation of each of the detection sensors 121 and 122 results in an error. In contrast, in the final (B4) operation, when the first detection sensor 121 detects that the movable accessory 110 is present at the initial position, the initial operation is normally completed.

  By executing such a series of operations, the initial operation is completed, and the rendering operation of the movable accessory 110 can be executed. Here, when the movable accessory 110 reaches the initial position, it is normal that the detection signal of the first detection sensor 121 switches from OFF to ON, and when the movable accessory 110 reaches the final position, the second detection is performed. It is normal for the detection signal of the sensor 122 to switch from OFF to ON. In this initial operation, if the detection signals of the first detection sensor 121 and the second detection sensor 122 are simultaneously ON, it operates as a sensor error (connector not connected, harness disconnection, sensor failure, etc.). Stop processing.

<< Directing action >>
Subsequently, the effect operation of the movable accessory 110 is an operation according to the effect operation pattern determined in conjunction with the decorative pattern variation pattern. Here, in the effect operation pattern, the operation content of the movable accessory 110 is defined by the number of steps of the stepping motor 160, the driving speed, the rotation direction, the operation time, and the like. Here, with reference to FIG. 10 and FIG. 13, the production operation based on the production operation pattern C (basic operation pattern) will be described. (C1) The movable accessory 110 stands by at the initial position, and (C2) the movable accessory 110. (C3) The movable combination 110 is held at the final position, (C4) The movable combination 110 is lowered, and (C5) The movable combination 110 is stopped at the initial position. Become. Here, “holding” means that the rotor 161 holds the current position in a state in which the excitation mode is maintained without switching the excitation phase (a state in which an excitation current continues to flow through the same stator coils L0 to L3). Say. On the other hand, “stop” means stopping the position of the rotor 161 in the excitation OFF state. In the ascending operation and descending operation of the movable accessory 110, the motor acceleration period (4 steps) → the motor constant velocity period (151 steps) → the motor deceleration period (4 steps) is set by changing the pulse frequency. ing.

  During such a series of performance operations, as the voltage switching condition, when “the stepping motor 160 is being excited” and “the operation of the movable accessory 110 is not being held (holding)”, that is, the movable accessory 110 is During operation, the supply voltage applied to the stepping motor 160 is switched from the first driving voltage (12V) to the second driving voltage (16V), and the driving torque of the stepping motor 160 increases. Can be moved up and down stably. On the other hand, when the voltage switching condition is not satisfied, that is, when the movable accessory 110 is held at the final position, the supply voltage applied to the stepping motor 160 is changed from the second drive voltage (16V) to the first drive. Since the voltage (12V) is switched, the power consumption for holding the movable accessory 110 at the final position can be reduced, so that the stepping motor 160 can be prevented from being damaged due to overheating.

  At this time, as will be described in detail later, in the production operation {(C1) → (C3) ascending operation or (C3) → (C5) descending operation}}, the movable accessory 110 is moved to the first detection sensor 121. If the movable sensor 110 is not detected at the initial position or the final position by each of the detection sensors 121 and 122 even if the operation is performed for 159 steps between the movable sensor 110 and the second sensor 122, the movable instrument 110 is detected. Is determined to be abnormal. When an abnormality occurs in the operation of the movable accessory 110 as described above, an error recovery operation for restoring the movable accessory 110 to a normal operation state is executed (the error recovery operation will be described later).

  Next, the symbol variation start condition satisfaction determining means 1138 determines the variation start condition for the first special symbol and the second special symbol (not being in a special game, not being varied in the first special symbol or the second special symbol, etc.) Judgment processing of whether or not is satisfied. Further, the symbol variation start condition satisfaction determining unit 1138 reserves the start of the other variation display while one of the first special symbol and the second special symbol is variably displayed. In the present embodiment, the symbol variation start condition satisfaction determining means 1138 preferentially executes variation display of the second special symbol over the first special symbol. That is, while the second lottery random number value is held in the second special figure holding means 1132, even if the first lottery random value is held in the first special figure holding means 1131, the second special figure holding means 1132 is held. The second lottery random number value that is held in is preferentially digested. Thereby, as long as the state that the second lottery random number value is held by the second special figure holding means 1132 is maintained, the second special drawing lottery can be continuously executed.

  Next, the symbol content determination means 1140, based on the acquired first lottery random value (particularly, the first special symbol lottery random value, the first variation pattern lottery random value), the stop symbol and variation pattern of the first special symbol Based on the first special symbol content determining means 1141 for determining the second special symbol and the acquired second lottery random value (particularly, the second special symbol lottery random value and the second variation pattern lottery random value). And the second special figure content determining means 1142 for determining the fluctuation pattern, and the stop symbol and the fluctuation of the normal symbol based on the acquired general symbol lottery random value (in particular, the normal symbol lottery random value and the common symbol variation pattern lottery random value). And a general-purpose content determining means 1143 for determining a pattern.

And an electric chew release time management timer 1162 to be managed. The electric chew opening / closing control means 1160 refers to the electric chew opening time determination reference table 1163, and when the winning / failing lottery is won in the short time state of the normal symbol, the electric chew opening / closing control means 1160 opens for a relatively long time compared to the normal state {normal symbol Release time α when the short time flag is on = 3 seconds (long time), open time β when the normal symbol time short flag is off = 0.1 seconds (short time)}.

  Next, the special game control means 1170 determines whether or not the condition for shifting to the special game (big hit) is satisfied. Specifically, the special game (big hit) execution permission flag is won. If the condition determination means 1171 for determining whether or not has occurred and the special game transition condition is satisfied, the content of the special game (specifically, the big winning opening to be opened, the number of rounds, A special game content determining means 1172 that sets a special game related information temporary storage means 1191c and a first big prize opening 64 or a second big prize opening 65 in an open state under predetermined conditions (round time, etc.) Special game execution means 1173 for executing a big hit) and a special game for performing time management of various processes related to the special game (for example, management of opening and closing times of the first big prize opening 64 and the second big prize opening 65) It has a while managing unit 1174, the. Here, the special game time management means 1174 further includes a round execution timer 1174a for managing the round time. The special game content determination unit 1172 further includes a special game content reference table 1172a that is referred to when specifying the content of the special game to be set in the special game related information temporary storage unit 1191c.

  When the lottery result related to the first special drawing lottery indicates the transition to the special game, the special game control means 1170 has the special game operation condition when the first special symbol is stopped in a predetermined hit state. It is determined that the game has been established, and the special game is executed by opening the first grand prize port 64 or the second grand prize port 65. Similarly, the special game control means 1170, when the lottery result related to the second special figure lottery indicates the transition to the special game, the special game control means 1170 is displayed when the second special symbol is stopped in a predetermined hit state. It is determined that the operating condition is satisfied, and the special game is executed by opening the first grand prize winning port 64 or the second grand prize winning port 65. The special game is a game in which the opening / closing operation of the first grand prize winning port 64 or the second grand prize winning port 65 is continuously continued a plurality of times, and is composed of a plurality of unit games (rounds) with one opening / closing as a unit. Is done. The special game control means 1170 ends the special game when the set round number (15 rounds or 2 rounds) of the unit game is consumed.

  The small hit game control means 1175, when the lottery result related to the first special drawing lottery results in the transition to the small hit game, the small hit game when the first special symbol is stopped in a predetermined hit state. It is determined that the operating condition has been established, and the small winning game is executed by opening the first big prize opening 64 or the second big prize opening 65. Similarly, if the lottery result related to the second special drawing lottery indicates a transition to the small hit game, the small hit game control means 1175 will stop when the second special symbol is stopped in a predetermined hit mode. It is determined that the small winning game operating condition is satisfied, and the small winning game is executed by opening the first big winning port 64 or the second big winning port 65. The small hit game is different from the special game in that it is composed of one unit game. Here, when the 2R special game and the small hit game described above are compared, although they are internally different, the point of the same opening / closing time (0.25 seconds) and the number of times of opening / closing are the same (the former is Since one opening and closing per round is twice in two rounds, and the latter is common in two opening and closing per round twice, a game with an approximate opening time / opening pattern is developed.

  Next, the specific game control means 1180 includes a specific game availability / content determination means 1183 that determines the content of the specific game, and a specific game end condition determination means 1181 that determines whether or not the specific game state end condition is satisfied. And having. Here, the specific game end condition determining means 1181 has a short time counter 1181a capable of counting a special symbol short time (ordinary symbol short time). Here, the “specific game” is, for example, a probability variation state in which a lottery probability for a special game is higher than that in the normal game, a short time state in which the variation time of the special symbol is relatively shorter than that in the normal game, and the second special figure. It refers to a normal game such as an electric chew support state in which the ease of entering the starting port 62 is enhanced.

  The specific game control means 1180 controls the normal game in the probability changing state, the short time state, and the electric chew support state. The specific game control means 1180 shifts the game state to the short-time state and the electric chew support state after the end of the special game. On the other hand, the transition to the probability variation state after the end of the special game is limited to the case where the special symbol determined by the symbol content determination means 1140 is a jackpot symbol accompanied by the transition to probability variation. The short-time state and the easy-to-open state are continued until the number of times that the special symbol fluctuates reaches a predetermined number of end conditions, for example, 100, counting from the end of the special game. However, when shifting to the probability changing state at the same time, as long as the probability changing state continues, the time reduction state and the electric chew support state are continued. That is, it continues until the next big hit. As described above, the end of the time reduction state and the electric chew support state is determined according to the gaming state. In the short-time state, a variation pattern with a particularly short variation time tends to appear. In the electric chew support state, the normal symbol is shortened, the normal symbol is changed, and the opening time of the electric accessory 622 is extended. On the other hand, the probability variation state is continued until a special game with the next jackpot is executed. During the probability change state, the probability that the success / failure lottery result by the success / failure lottery means 1135 becomes a big hit is maintained at a high value. The specific game propriety / content determination means 1183 turns on the “special symbol probability change flag” in the probability change state and sets the “special symbol time reduction flag” in the time reduction state when determining the transition content to the specific game related to the special symbol. turn on. In this embodiment, the “ordinary symbol time flag” is also turned on in conjunction with the “special symbol time flag”. Note that, as will be described in detail later in the processing column, when the “special symbol time-short flag” is turned off, the “normal symbol time-short flag” is also turned off.

  Next, the game related information temporary storage means 1190 is a special chart for temporarily storing information related to special figure games (main game) such as control related to special symbols and control related to special games and small hit games. Game related information temporary storage means 1191 and general game related information for temporarily storing information related to the general game, such as control related to normal symbols and information related to the electric accessory 622 of the second starting port 62 Temporary storage means 1192.

  Here, the special figure game related information temporary storage means 1191 temporarily stores on / off information of various flags in various gaming states relating to the first special figure game and the second special figure game, and the first special symbol and the second special symbol.

  Further, the general-purpose game-related information temporary storage means 1192 temporarily stores general-purpose game-related information temporary storage means 1192a for temporarily storing information related to display control of normal symbols, and information related to the game state on the general-purpose game side. And a normal game side game state temporary storage means 1192b.

  The power-off processing control unit 1400 includes a power-off information temporary storage unit 1410 for temporarily storing information related to a state at the time of power-off.

<Sub control board>
The sub control board 2000 performs effect display control on the effect display device 70 based on the information receiving means 2100 for receiving commands and various information from the main control board 1000 side, and commands from the main control board 1000 side. Effect display control means 2200 for controlling, movable accessory control means 2300 for controlling the operation of the movable accessory unit 100, and general presentation information (including flags) relating to processing executed on the sub-control board 2000 side are temporarily stored. Production-related information temporary storage means 2400 for this purpose.

  The information receiving means 2100 has main-side information temporary storage means 2110 for temporarily storing symbol information related to the special figure game from the main control board 1000 side. The information temporarily stored here is appropriately referred to as necessary by each means described later in each process described below.

  The decorative symbol display control means 2210 is a display for determining a decorative symbol stop symbol and a variable effect pattern based on the symbol information from the main control board 1000 side temporarily stored in the main side information temporary storage unit 2110. Content determination means 2211 and a drawing change pattern storage means for storing all data related to the effect display including data (various object data, moving image data, audio data, etc.) related to the decorative design and the change design pattern of the decorative design. 2212. Here, the drawing display content determination means 2211 is referred to when determining the drawing stop symbol determination lottery table 2211a for reference when determining the stop symbol of the decorative symbol and the variation effect pattern of the decorative symbol. And a drawing variation content determination lottery table 2211b for the purpose.

  The decorative symbol display control means 2210 is configured to determine a decorative symbol stop symbol and a variable effect pattern based on special symbol information (stop symbol information and variation pattern information) transmitted from the main control board 1000 side. . In addition, about the stop design of the decorative design, it is determined by lottery based on the attribute information of the special symbol in the case of winning, and in the case of losing, it is determined by lottery based on whether it is reach or non-reach, The decorative design variation effect pattern is uniquely specified based on the special symbol variation pattern, but is not limited to this. For example, the decoration symbol may be uniquely determined by being tied to the special symbol stop symbol.

  The stop symbol of the decorative symbol is formed as a combination of three symbols. For example, when the result of winning / not-winning lottery means 1135 indicates a transition to 15R special game, a specific combination such as “777” or “111” is used. Thus, a combination of three symbols is selected. A specific combination, for example, a predetermined combination such as “357”, is also selected when the result of the lottery result indicates a shift to 2R special game or a small hit. That is, the specific combination of 2R big hit or small hit does not necessarily have to be a combination of three symbols. If the winning / losing lottery result is neither big hit nor small hit, it is a combination that does not have three symbols such as “312” and “946”, and is a specific combination that is selected at the time of 2R big hit or small hit A combination that does not apply is selected. If the winning / raising lottery result is not 15R big hit, and a variation effect pattern indicating a loss with reach is selected, a combination that does not have only one symbol such as “191” or “727” is selected. .

  The decorative design variation effect pattern defines a variation display mode of the decorative symbol, that is, a series of effect display processes from the start of variation of the decorative symbol to the end of variation. The variation effect pattern includes a pattern for displaying a normal lost symbol and a pattern for displaying a lost symbol or a big hit symbol through a reach state that is a big hit if one more symbols are aligned. In particular, the pattern that passes through the reach state includes patterns having various fluctuation times. For example, normal reach refers to a mode in which two out of three symbol sequences temporarily stop, and then the remaining one symbol sequence fluctuates. Super reach refers to two out of three symbol sequences temporarily. After stopping, it means a mode in which the remaining one symbol sequence fluctuates frame-by-frame.

  Next, the drawing hold information display control means 2220 has a hold information temporary storage means 2221 for temporarily storing various information related to the hold.

  In addition, the effect display control means 2200 performs control related to effects other than image display, such as effect processing such as lighting and extinguishing of the effect lamp 10 and sound output from the speaker 11.

  The movable accessory control means 2300 includes an initial operation control means 2310 that controls the initial operation of the movable accessory 110, an effect operation control means 2320 that controls the effect operation of the movable accessory 110, and a stepping motor 160. A set step number temporary storage means 2330 for temporarily storing the number of steps to be driven according to a predetermined operation pattern (initial operation pattern, effect operation pattern, return operation pattern), and how many steps the stepping motor 160 has operated is counted. A step counter 2340, and a movable accessory operation related information temporary storage unit 2350 for temporarily storing information related to the operation state of the movable accessory unit 100.

  The initial operation control means 2310 controls the initial operation of the movable accessory 110 according to a predetermined initial operation pattern when the pachinko gaming machine PM is turned on. The initial operation control unit 2310 has an initial operation pattern storage unit 2311 for storing data relating to the initial operation pattern. In the present embodiment, as described above, two different initial motion patterns A and B are prepared according to the current position of the movable accessory 110 at the start of the initial motion.

  The effect operation control means 2320 includes an effect operation execution means 2321 that performs control for causing the movable accessory 110 to operate according to the effect action pattern, an abnormality determination means 2322 that determines whether or not the operation of the movable accessory 110 is abnormal, and a movable When it is determined that the operation of the accessory 110 is abnormal, the first return processing execution means 2323 for executing the first return processing for returning the movable accessory 110 to the initial position, and the first return processing And a second return process execution means 2324 that executes a second return process when the movable accessory 110 does not return to the initial position even if it is executed.

  The production operation execution means 2321 designates one production operation pattern from a plurality of production operation patterns, and the operation content (number of motor steps, drive speed, rotation direction, operation time, etc.) determined in the production operation pattern. In accordance with the control, the control for operating the movable accessory 110 is executed. The production operation execution unit 2321 is based on the production operation pattern storage unit 2321a for storing data related to the production operation pattern, and the voltage switching condition (“the motor is being excited” and “the operation is not being held”). The driving voltage supplied to the stator coils L0 to L3 of the stepping motor 160 is selectively switched between two levels (12V and 16V in this embodiment) to control the driving voltage (driving torque) of the stepping motor 160. Motor drive voltage switching control means 2321b.

  The effect operation pattern storage unit 2321a is referred to when determining an effect operation pattern in which a series of driving modes of the stepping motor 160 are defined to operate the movable accessory 110. At this time, among the plurality of variation effect patterns in the decorative design described above, the effect operation pattern of the movable accessory 110 is associated with some variation effect patterns, and the decoration symbol display content determination unit 2211 performs the variation. When the production pattern is selected, the production operation pattern of the movable accessory 110 corresponding to the variation production pattern is designated (execution request) from the production operation pattern storage unit 2321a. Here, in the effect operation pattern, the operation content of the movable accessory 110 is defined by, for example, the number of steps of the stepping motor 160, the driving speed, the rotation direction, the operation time, and the like. Here, the movement of the movable accessory 110 is set so that the movement starts from the initial position and finally returns to the initial position in accordance with the effect operation pattern, and is completed during one decoration pattern change. It is configured.

  The abnormality determination unit 2322 confirms the operation state of the stepping motor 160 based on the number of steps counted by the step counter 2340 and detection signals (ON / OFF signals) from the first and second detection sensors 121 and 122. Then, abnormality determination processing is executed to determine whether or not the rotor 161 of the stepping motor 160 is rotating correctly, that is, whether or not the movable accessory 110 is operating normally. This abnormality determination process is executed at a confirmation timing (such as at the start of the rendering operation, during the operation, or at the end) at which the movable accessory 110 is expected to exist at the initial position or the final position. For example, the abnormality determination unit 2322 may detect the first detection sensor even if the movable accessory 110 is moved in the downward direction (that is, the stepping motor 160 is moved in the forward direction CW) by 159 steps during the rendering operation of the movable accessory 110. 121, when the initial position is not detected, or when the final position is not detected by the second detection sensor 122 even if the movable accessory 110 is moved in the upward direction (that is, the stepping motor 160 is moved in the reverse direction CCW) for 159 steps. In addition, it is determined that the operation of the movable accessory 110 is abnormal.

  When it is determined that the operation of the movable accessory 110 is abnormal, the first return processing execution means 2323 is a first return processing for returning the movable accessory 110 to the initial position according to a predetermined return operation pattern. Perform error recovery. In the first return process, the stepping motor 160 is once operated in the reverse direction CCW (the upward direction in which the movable accessory 110 approaches the final position) for a predetermined number of steps, and then the forward rotation direction CW (the movable accessory 110 is moved). The movable accessory 110 is returned to the initial position by operating in the downward direction approaching the initial position. In this first return processing, even if the stepping motor 160 is rotated in the normal rotation direction CW by the maximum number of steps (in this embodiment, 159 steps between the first detection sensor 121 and the second detection sensor 122), An error occurs when the movable accessory 110 does not reach the initial position (the first detection sensor 121 is not turned ON). If the first return process results in an error, the first return process execution means 2323 repeatedly executes the first return process up to a predetermined number of retries (total of 3 times). If an error occurs three times in succession in the first return process, the process proceeds to the second return process described below.

  The second return process execution means 2324 is the second return process when the movable accessory 110 does not return to the initial position even in the first return process (when the first return process results in an error three times in succession). As the return processing, control for initial operation of the movable accessory 110 is executed. As described above, as the initial operation, as shown in FIGS. 11 and 12, the operations (A1) to (A6) based on the initial operation pattern A, or (B1) to (B) based on the initial operation pattern B are used. The operation B4) is executed. If an error occurs three times in succession in this initial operation (second return process), the operation process is stopped and error notification is performed.

[5. processing]
Next, the flow of processing of the pachinko gaming machine PM according to the present embodiment will be described with reference to the flowcharts of FIGS.

<Processing on the main control board>
First, the flow of processing on the main control board 1000 side will be described with reference to the flowcharts of FIGS. Here, the flowchart on the left side of FIG. 15 is a process executed on the main control board 1000 side at the normal time after the power is turned on. On the other hand, the flowchart on the right side of FIG. 15 is a power-off process that is executed in response to a power-off signal (NMI signal) that is generated when the power is cut off.

  First, the left side of FIG. 15 is a main flowchart showing a general processing flow executed on the main control board 1000 side. In step S1050, the main control board 1000 executes a power-off recovery initial process. Next, in step S1100, the main control board 1000 executes a winning process for performing a process related to winning at a starting port (including a general-purpose starting port contributing indirectly) related to special game transition. Next, in step S1350, the main control board 1000 determines whether or not a normal game is being played. If Yes in step S1350 (if a normal game is being played), in step S1400, the main control board 1000 executes a normal game control process (a process related to a normal symbol). Next, in step S1500, the main control board 1000 executes normal game processing (processing related to special symbols). On the other hand, if the answer is No in step S1350 (when the game is not in a normal game), the main control board 1000 executes a special game control process in step S1800. Next, in step S1900, the main control board 1000 executes a small hit control process. In step S1950, the main control board 1000 transmits a prize ball payout command to the payout control board 3000 based on the winning opening where the game ball has won, and performs a payout process for a predetermined number of prize balls. Return to S1050. Note that the special game of S1800 and the small hit game of S1900 are not executed simultaneously, and when one is executed, the other is avoided.

  FIG. 16 is a flowchart of the power-off reset initial process according to the subroutine of step S1050 in FIG. First, in step S1052, the power-off processing control unit 1400 refers to the flag area of the power-off information temporary storage unit 1410, and determines whether or not the main-side power flag is on. Here, the main-side power supply flag is a flag that is turned on in the power-off process S2000 that is executed in response to an NMI signal described later. That is, the situation where the main power flag is turned on in this processing (normal processing) is when the power is turned on again after the main control board 1000 is turned off. If Yes in step S1052, in step S1054, the power-off processing control unit 1400 accesses the flag area of the power-off information temporary storage unit 1410 to turn off the main power flag. Next, in step S1056, the information transmission unit 1200 transmits a movable accessory initial operation execution command to the sub-control board 2000 side. Here, the movable accessory initial operation execution command is a command for instructing an initial operation (excluding an initial operation at the time of return processing) of the movable accessory unit 100 controlled by the sub-control board 2000 side. Next, in step S1057, the power-off processing control unit 1400 refers to the game related information temporary storage unit 1190 to acquire information related to game state information, special symbol information, and the like, and the information transmission unit 1200 acquires the information. The transmitted information is transmitted to the sub-control board 2000 side. Next, in step S1058, the power-off processing control means 1400 refers to the flag area of the first special figure / second special figure game related information temporary storage means 1191a and determines whether or not the changing flag is on. (That is, whether or not the special symbol is changing). In the case of Yes in step S1058, in step S1060, the information transmission unit 1200 transmits the remaining fluctuation time of the special symbol temporarily stored in the power-off time information temporary storage unit 1410 to the sub-control board 2000 side. Next, in step S1062, the information transmission unit 1200 transmits a symbol variation start command to the sub-control board 2000, and proceeds to the next process (winning process in step S1100).

[6. Action]
Next, the operation of the pachinko gaming machine PM according to the present embodiment will be described with reference to FIGS. 32 and 33. FIG. FIG. 32 is a timing chart when the movable accessory 110 operates normally in accordance with a predetermined effect operation pattern. FIG. 33 shows the first return processing when it is determined that the operation position of the movable accessory 110 is abnormal. 4 is a timing chart when an error recovery operation is executed by a second recovery process.

  First, the timing chart of FIG. 32 will be described. At the timing (see box 1 in the figure) at which the decorative display pattern 70 starts to change and the rendering operation of the movable accessory 110 starts in the effect display device 70, the movable accessory 110 is displayed. An abnormality determination process is performed to determine whether or not is present at a normal operation start position (that is, an initial position) (see box 2 in the figure). Specifically, based on the detection signal (ON / OFF signal) from the first detection sensor 121, it is determined whether or not the movable accessory 110 is present at the initial position. Here, since the first detection sensor 121 is ON, it is determined that the movable accessory 110 is present at the initial position, and the rendering operation of the movable accessory 110 is started under a predetermined operation timing. First, the movable accessory 110 starts an ascending operation according to the effect operation pattern. At this time, since the voltage switching condition is satisfied, the voltage switching is turned on (see box 3 in the figure), and the movable accessory 110 is turned on. During the ascent operation, the supply voltage to the stepping motor 160 is the second drive voltage of 16 V (see box 4 in the figure).

  At the timing when the movable combination 110 moves up and reaches the final position, an abnormality determination process is performed to determine whether or not the movable combination 110 exists at the final position (see box 5 in the figure). Specifically, based on the detection signal (ON / OFF signal) from the second detection sensor 122, it is determined whether or not the movable accessory 110 is present at the final position. Here, since the second detection sensor 121 is ON, it is determined that the movable accessory 110 is present at the final position, and the operating position of the movable accessory 110 is held at this operating position for a predetermined time (in the drawing). (See box 6). At this time, since the voltage switching condition is not satisfied, the voltage switching is turned OFF (see box 7 in the figure), and the supply voltage to the stepping motor 160 is the first drive while the movable accessory 110 is held at the final position. The voltage is 12V (see box 8 in the figure). The movable accessory 110 is held at the final position by the holding torque of about 75% (= 12V / 16V) output.

  After a predetermined time has passed, the movable accessory 110 starts to move downward. At this time, since the voltage switching condition is satisfied, the voltage switching is turned ON again (see box 9 in the figure), and the movable accessory 110 While 110 is descending, the supply voltage to the stepping motor 160 is the second drive voltage of 16V (see box 10 in the figure). Then, at the timing when the movable accessory 110 moves down to reach the initial position (see box 11 in the figure), an abnormality determination process is performed to determine whether or not the movable accessory 110 exists at the initial position ( (See box 12 in the figure). Specifically, based on the detection signal (ON / OFF signal) from the first detection sensor 121, it is determined whether or not the movable accessory 110 is present at the initial position. Here, since the first detection sensor 121 is ON, it is determined that the movable accessory 110 is present at the initial position, and the effect operation of the movable accessory 110 is normally completed. When the movable accessory 110 is stopped at the initial position, the supply voltage to the stepping motor 160 is 0 V (excitation off state), but a static torque can be obtained even in the non-excitation state. And after that, with the opportunity that the movable accessory 110 is waiting at the initial position, the movable accessory 110 executes the effect operation according to the effect operation pattern every time the decoration symbol on the effect display device 70 changes. It becomes.

  Next, the timing chart of FIG. 33 will be described. This timing chart shows a case where it is determined that the stepping motor 160 is not rotating normally (step out) during the rendering operation of the movable accessory 110. As shown in FIG. 33, first, the decorative display pattern 70 starts to change in the effect display device 70, and the stepping motor 160 has an abnormality when the movable accessory 110 performs the effect operation (the ascending operation) according to the effect operation pattern. (See box 1 in the figure). At the timing when the movable accessory 110 reaches the final position, an abnormality determination process is performed to determine whether or not the movable accessory 110 is present at the final position (see box 2 in the figure). Specifically, based on the detection signal (ON / OFF signal) from the second detection sensor 122, it is determined whether or not the movable accessory 110 is present at the final position. As shown in the figure, as a result of referring to the detection signal from the second detection sensor 122, the second detection sensor 122 is normally ON (the dotted line portion in the column of “second detection sensor” in the figure). However, if the second detection sensor 122 is OFF, it is determined that the operation of the stepping motor 160 is abnormal, and the error flag is turned ON (see box 3 in the figure). In addition to the step-out, the stepping motor 160 malfunctions, such as a minor abnormality that waits at a position lower than the final position due to its own weight or inertia, or a movable accessory interferes with another accessory. There is a serious abnormality that hinders the operation of the stepping motor.

  In response to the error flag being turned ON, first, a first return process for returning the movable accessory 110 to the initial position is executed (see box 4 in the figure). However, in the case of a motor step-out or a severe abnormal state as described above, the factor that hinders the operation of the movable accessory 110 is not eliminated even by the first return processing, and the movable accessory 110 is in the initial position. It may not return to In this case, in response to the ON state of the error flag being continued (the first return process is an error three times in succession), the second for returning the movable accessory 110 to the initial position. A return process is executed (see box 4 in the figure). In this second return process, as an initial operation of the movable accessory 110 (initialization operation at power-on), as shown in FIGS. 11 and 12, an initial operation pattern A {(A1) → (A2) → ( The initial operation is executed in accordance with A3) → (A4) → (A5) → (A6)} or initial operation pattern B {(B1) → (B2) → (B3) → (B4)}. When the second return process (initial operation) is completed and the movable accessory 110 returns to the initial position normally, the first detection sensor 121 is turned on (see box 5 in the figure), and an error flag is set. Is turned off (see box 6 in the figure). Thereby, the abnormal state of the movable accessory 110 is eliminated. Then, after that, the movable accessory 110 executes the rendering operation according to the rendering operation pattern every time the decoration symbol on the rendering display device 70 changes, triggered by the movable accessory 110 being in the initial position. It becomes.

  As described above, in the pachinko gaming machine PM according to the present embodiment, it is necessary to separately prepare a program for the return process by using the initialization operation when the power is turned on as the return process when an abnormality occurs in the stepping motor 160. Therefore, it is possible to eliminate the abnormal state by returning the movable accessory 110 to the initial position while reducing the program capacity.

  In the pachinko gaming machine PM according to the present embodiment, as a return process when an abnormality occurs in the stepping motor 160, a first return process for causing the movable accessory 110 to return according to a predetermined return operation pattern, and a movable combination Since the object 110 has a two-stage process pattern including a second return process for returning the object 110 according to the initial operation pattern (initial operation), an appropriate return operation corresponding to the severity of the abnormal state of the movable accessory 110 is performed. Realized, it is possible to reliably return the movable accessory 110 to the initial position and use it for the production operation, and realize a two-step return process with a simple control configuration using the initialization operation as one return process. It becomes possible to do.

  In the pachinko gaming machine PM according to the present embodiment, when the movable accessory 110 is held at the final position, the first driving voltage is supplied to the stepping motor 160 when the movable accessory 110 is held at the final position, and the movable accessory 110 is held at the final position. By reducing the power consumption for the operation, it is possible to prevent the stepping motor 160 from being damaged due to excessive heat generation or the like. On the other hand, the second driving voltage is supplied to the stepping motor 160 when the movable accessory 110 is moved up and down. By increasing the driving torque of the motor 160, the movable accessory 110 can be smoothly operated even when the movable accessory 110 having a large and heavy weight is employed. In addition, since the operation content (operation information of voltage switching ON / OFF) for switching the driving voltage to the stepping motor 160 can be included in the rendering operation program of the movable accessory 110, the operating state of the movable accessory 110 Accordingly, it is not necessary to prepare a separate program for determining whether or not to switch the drive current according to the above, so that the program capacity can be reduced.

  Further, in the pachinko gaming machine PM according to the present embodiment, in the motor drive circuit, the supply voltage to the stepping motor can be selectively switched to the first drive voltage or the second drive voltage only by turning on / off the switching element. Therefore, the circuit configuration is simplified.

  Note that when the movable accessory 110 is held at the final position during the production operation, the supply voltage to the stepping motor 160 is switched to the first driving power (12V) lower than the second driving power (16V). It is configured to switch excitation ON / OFF of the stepping motor 160 at a minute interval of 1000 seconds (ie, by controlling the duty ratio to be small and shortening the energization time) to reduce power consumption and excessive stepping motors You may make it prevent heat generation more reliably.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and can be improved as appropriate without departing from the gist of the present invention.

  In the above-described embodiment, the description has been made by exciting the configuration in which the movable accessory operates in the vertical direction on the front surface of the effect display device. However, the present invention is not limited to this. Even if it operates in the direction, it may operate outside the front face of the effect display device. Note that the mode of operation is not limited to a linear slide operation, and may be a rotation operation, a swing operation, or the like.

  In the above-described embodiment, the voltage switching is turned ON during the rendering operation (elevating operation) of the movable accessory, and the second driving voltage 16V higher than the first driving voltage is supplied to the stepping motor 160. However, the present invention is not limited to this, and the voltage switching may be turned on during the return operation of the movable accessory (first return process or second return process). According to this configuration, since the driving torque of the stepping motor increases during the return operation of the movable accessory, the possibility of returning the movable accessory to the initial position can be further increased.

  In the above-described embodiment, the photo sensor composed of the light projecting element and the light receiving element has been exemplified and described as the rotating object detection means, but is not limited to such an optical sensor, other non-contact type sensors, A contact sensor may be applied.

  In the above embodiment, the case where the present invention is applied to a pachinko game machine has been described. However, an arrangement ball machine, a sparrow ball game machine, an enclosed game machine (a predetermined number of game balls are enclosed in the machine and used in circulation) It can be applied to other gaming machines such as a gaming machine, and similar effects can be obtained.
