Moreover, the time when the two LED lamps are alternately blinking is a normal symbol variation time.

Next, the structure and operation of the first movable body B1 and the second movable body B2 will be described with reference to FIGS.
FIG. 3 is a front view showing the internal structure of the first movable body B1. As shown in the figure, the first movable body B1 is stored on the back of the central decoration 51 and the movable body lifting / lowering driving device 70 stored on the back of the central decoration 51, and is moved up and down by a pair of link arms. The elevating operation is performed by the elevating support mechanism 80 that supports the elevating operation of the first movable body B <b> 1 driven by the driving device 70.

  The movable body lifting and lowering driving device 70 converts the motor M1 and the power transmitted to the first movable body B1 by converting the rotational force of the motor M1 into a force that reciprocates up and down on a plane parallel to the board surface of the game board 30. And a mechanism 71. The power transmission mechanism 71 is connected to a first gear 73 that rotates by being attached to the output shaft 72 of the motor M1, a second gear 74, and a projecting shaft 75 that projects from the disc surface of the gear material of the second gear 74. Arm 76.

The casing of the motor M1 is fixed to the component mounting base 77 of the game board 30 and the rotation center shaft 74A of the second gear 74 is rotatably mounted to the component mounting base 77.
The motor M1 and the second gear 74 are disposed on the component mounting base 77 at a position where the teeth of the first gear 73 and the teeth of the second gear 74 that rotate by receiving the rotational force of the motor M1 mesh with each other. Due to the rotation of M1, the second gear 74 rotates in one direction.

In the connecting arm 76, the end portion of the one-side linear shaft portion 76A and the end portion of the other-side linear shaft portion 76B are connected to each other by the linear shaft portions 76C perpendicular to the linear shaft portions 76A and 76B. Formed by a crankshaft. A long hole 76D that is long in the direction along the straight line of the one-side linear shaft portion 76A is formed on one end side of the one-side linear shaft portion 76A.
The other end side of the other-side linear shaft portion 76B is connected at a portion located on a vertical line passing through the left and right center of the back surface of the first movable body B1. The connecting arm 76 is attached to the component attachment base 77 via a rotation center shaft 76E provided at the other end of the one side linear shaft portion 76A. And the protrusion shaft 75 and the other end part of the one side linear shaft part 76A of the connection arm 76 are connected so that the protrusion shaft 75 can move in the long hole 76D.

  In this way, when the motor M1 rotates in the X direction shown in FIG. 3A in a state where the motor M1 is connected to the first movable body B1 via the connecting arm 76, the first gear 73 and the second gear The gear 74 rotates, the projecting shaft 75 formed on the second gear 74 presses the hole wall of the long hole 76D, and the connecting arm 76 rotates about the rotation center shaft 76E as the rotation center. The connecting portion with the first movable body B1 which is the other end of 76B is lowered. Then, following the lowering of the connecting arm 76, the first movable body B1 connected to the connecting arm 76 is lowered from the ascending limit position shown in FIGS. 2 and 3 (a) as shown in FIG. 3 (b). Lower to the limit position. At this time, the pair of link arms in the lifting support mechanism 80 is displaced from the folded state to the gradually extended state as the first movable body B1 is lowered.

  On the other hand, when the motor M1 rotates in the Y direction from the state shown in FIG. 3B, the connecting arm 76 rotates again about the rotation center shaft 76E and is the other end of the other side linear shaft portion 76B. A connection part with 1st movable body B1 raises. Then, following the ascent of the connecting arm 76, the first movable body B1 connected to the connecting arm 76 rises as shown in FIGS. 2 and 3 (a) from the lower limit position shown in FIG. 3 (b). Ascend to the limit position. At this time, the pair of link arms in the elevating support mechanism 80 returns from the extended state to the folded state as the first movable body B1 is raised.

  When the first movable body B1 according to the present embodiment is operated, the load torque of the motor M1 is larger when the first movable body B1 is lowered than when the first movable body B1 is lowered due to the action of its own weight. Therefore, more driving torque is required. For the motor M1 for operating the first movable body B1 including such an operation pattern, a circuit configuration capable of ensuring a torque margin is adopted, and the torque required according to the operation pattern of the first movable body B1 The first movable body B1 can be operated stably and smoothly. A specific circuit configuration will be described later.

FIG. 4 is a perspective view showing the structure of the second movable body B2. As shown in the figure, the second movable body B2 is constituted by a pair of left and right opening / closing bodies 90A; 90B, and the opening / closing operation of the opening / closing bodies 90A; 90B is performed by an opening / closing operation driving device 89 including motors M2; M3, respectively. Realized.
The opening / closing operation driving device 89 is generally constituted by a pair of motors M2; M3 disposed so as to face each other, and a pair of screw shafts 96A; 96B respectively connected to the motors M2; M3. The configuration of the screw shaft 96A rotated by the motor M2 and the configuration of the screw shaft 96B rotated by the motor M3 are the same, and therefore only the one motor M2 and the screw shaft 96A will be described for the sake of simplification.

  The motors M2 and M3 are mounted in an accommodation space provided on the back surface of the stage 55 via a mounting substrate 91A, and their output shafts extend coaxially in the left-right direction. The motor M2 has a gear 92A attached to the output shaft, and the gear 92A meshes with a gear 97 fitted to one end of one screw shaft 96A. The screw shaft 96A is a rod-like body that meshes with one motor M2 and extends leftward. Further, the screw shaft 96A is arranged in a state of being displaced in the front-rear direction with respect to the screw shaft 96B, and is arranged in a state of being overlapped in the longitudinal direction. The other end of the screw shaft 96A is rotatably supported via a mounting base 99 that is mounted in a receiving space provided on the back surface of the stage 55, and rotates in one direction as the motor M2 rotates. To do.

  A spiral groove is formed on the outer peripheral surface of the screw shaft 96A along the axial direction. Further, on the inner peripheral surface of the guide cylinder 98 formed at the lower part of the opening / closing body 90A, a spiral protrusion is formed that engages with a spiral groove formed on the outer peripheral surface of the screw shaft 96A. When the screw shaft 96A is rotated in a state where the screw shaft 96A is inserted into the guide cylinder 98, the opening / closing body 90A operates in the axial direction (left-right direction) of the screw shaft 96A according to the rotation direction.

The second movable body B2 configured as described above closes the front of the effect display device 50 from the open state by rotating one of the motors M2 and M3 or both synchronously in one direction. Transition to a state or from a closed state to an open state.
Since the load torque of the motor M2; M3 when the second movable body B2 is changed only in one direction of the closing direction or the opening direction, the opening / closing body 90A; 90B only repeats the movement in the substantially horizontal direction. There is no change in the opening operation, and when compared with the stepping motor M1 described above, it is not necessary to consider the securing of the torque margin due to the operation pattern.
On the other hand, for example, an operation pattern is assumed in which the second movable body B2 in the open state is operated in the closing direction and the vibration operation (rattle operation) is performed in the left-right direction (opening / closing direction) at the stop position before the fully closed state. In this case, since it is necessary to continuously and instantaneously switch the rotation direction of the motor M2; M3 between forward rotation and reverse rotation (acceleration and deceleration), a drive torque for instantaneously obtaining a predetermined rotation speed is required. The

The drive circuits and operations of the motors M1; M2; M3 will be described below with reference to FIGS.
As shown in FIG. 5, the drive circuit of the stepping motors M1; M2; M3 outputs a pulse signal from each port in accordance with the drive data output from the movable body control unit 200D constituting the sub-control device 200.

Further, the voltage applying unit 900 supplies power supply voltages to be input to the stator coils L1 to L4 of the motors M1; M2; M3 based on a voltage conversion signal output from the movable body control unit 200D via the driver board 500. A voltage switching control unit 600 for switching, a first power supply voltage applying unit 700A for applying a power supply voltage (VM1 = 12V, VM2 = 18V) to the motors M1, M2, M3, respectively, and a second power supply voltage applying unit 700B And a power supply voltage monitoring unit 800 for monitoring the power supply voltage applied from the second power supply voltage applying means 700B.

  The motors M1; M2; M3 in this embodiment are, for example, a four-phase unipolar type, and are output from the power supply voltage supplied from the first power supply voltage applying means 700A or the second power supply voltage applying means 700B and from the driver board 500. The drive is controlled by pulse signals (φ1 to φ4). As shown in the figure, one end of each of the stator coils L1 to L4 of the motors M1; M2; M3 is connected to each port for outputting a pulse signal in the driver substrate 500 via signal lines 501 to 504. The other end portions of the stator coils L1; L3 and L2; L4 are connected in series, and are connected to the first power supply voltage applying means 700A side and the second power supply voltage applying means 700B side by a common power supply line 510; 511. Has been.

  As described above, the motors M1; M2; M3 in the present embodiment have a concern that the drive pattern may be insufficient due to the operation pattern, and in order to compensate for the torque shortage during the operation pattern, the first power supply voltages having different voltages may be applied. The power supply voltage from the means 700A and the second power supply voltage applying means 700B can be input, and the first movable body B1 in the ascending operation or the second movable body B2 in the left-right vibration operation. It is a circuit configuration in which the operation is performed smoothly. Hereinafter, the configuration of each unit will be described.

  The driver board 500 is a relay board disposed in a different area from the sub-control device 200 (movable body control unit 200D) on the back surface of the game board 30, and is a control pulse for the motors M1; M2; M3. In addition to a plurality of ports that can output signals φ1 to φ4, a port P1 that can output a voltage switching signal (Hi level) according to a voltage conversion signal from the movable body control unit 200D is provided. The voltage switching signal output from the port P1 is input to the voltage switching control unit 600 via the signal supply line 601.

The voltage switching control unit 600 is a relay board disposed in the vicinity of the driver board 500 on the back of the game board 30, and based on the input of the voltage switching signal from the driver board 500, the stepping motor M <b>1; M2: The power supply voltage output to the M3 side is switched to the first voltage VM1 or the second voltage VM2.
Specifically, one end of the signal supply line 601 is connected to the base of an npn transistor Q2 via a resistor R1. The emitter side of the transistor Q2 is grounded, and the collector side is connected to the second power supply voltage applying unit 700B and the gate side of the FET Q1 via the signal supply line 602. A resistor R2; R3 is connected in series between the collector of the transistor Q2 and the second power supply voltage applying means 700B, and a resistor R2 is interposed between the collector of the transistor Q2 and the gate of the FET Q1.

  The FET Q1 is a MOS field effect transistor, for example, and has a source side connected to the second power supply voltage applying unit 700B via a power supply line 603 and a drain side connected to the anode side of the diode D2 via a power supply line 604. ing. The cathode side of the diode D2 is connected to the motor M1 through the power supply line 605 connected to the power supply lines 510 and 511 described above. The diode D2 prevents the current from the first power supply voltage applying unit 700A side from flowing into the drain side of the FET Q1.

  The second power supply voltage applying means 700B connected to the motors M1; M2; M3 via the power supply switching control unit 600 always applies a predetermined power supply voltage (18V) to the power supply switching control unit 600 and the motors M1; M2; M3 side. It is comprised by the power supply circuit or power supply element to apply. The power supply voltage applied by the second power supply voltage applying means 700B is set to be higher than the power supply voltage applied by the first power supply voltage applying means 700A described later, and the voltage is the heat generation temperature of the motors M1; M2; M3. If it is within the allowable range, it can be set freely.

On the other hand, the first power supply voltage applying means 700A is connected to the motors M1; M2; M3 via the power supply line 701 in the same manner as the second power supply voltage applying means 700B. A diode D1 is interposed in the power supply line 701 in the forward direction when viewed from the first power supply voltage applying unit 700A, and current is prevented from flowing from the second power supply voltage applying unit 700B side when the power supply voltage is switched.
The first power supply voltage applying means 700A is composed of a power supply circuit or a power supply element that constantly applies a predetermined first power supply voltage VM1 (12V) to the motors M1; M2; M3, and includes a first movable body B1 and a second movable body. During an operation in which torque shortage is not expected due to the operation pattern of the body B2, a power supply voltage (normal voltage) of 12V is supplied to the motors M1; M2; M3. On the other hand, at the time of operation in which torque shortage is assumed by the operation pattern of the first movable body B1 or the second movable body B2, the second power supply voltage VM2 of 18 V, which is higher than the normal voltage, is supplied.

The power supply voltage monitoring unit 800 is connected to a power supply line 605 that supplies a power supply voltage from the second power supply voltage application unit 700B and a power supply line 701 that supplies a power supply voltage from the second power supply voltage application unit 700B. Connected.
Specifically, the power supply voltage monitor unit 800 is connected in series with the resistor R4 connected to the connection portion between the power supply line 605 and the power supply line 701 via the power supply line 801. Zener diode ZD1 and LED 1 connected to the anode side of the Zener diode ZD1.
That is, both the power supply voltages from the first power supply voltage applying unit 700A and the second power supply voltage applying unit 700B are applied to the cathode side of the Zener diode ZD1 of the power supply voltage monitoring unit 800.
Hereinafter, the flow during power supply voltage switching will be described with reference to FIGS.

FIG. 6 shows the rotation speed (pps) of the motor M1 and the power supply switching signal (V) on the assumption that the first movable body B1 descends from the ascent limit position to the ascent limit position and then returns to the ascent limit position again. And a time chart schematically showing a pulse voltage (V).
As described above, during the lowering operation of the first movable body B1, the voltage conversion signal is not output from the movable body control unit 200D, the voltage switching signal is maintained at the low level (0 V), and the transistor Q2 is turned on. Since the predetermined voltage is not applied to the base side, the transistor Q2 is turned off. When the transistor Q2 is OFF, the current flowing from the second power supply voltage applying unit 700B branches to flow to the resistor R3 and the source of the FET Q1. Further, the current flowing through the resistor R3 tends to flow through the resistor R2 connected to the gate of the FET Q1 and the collector of the transistor Q2. Since the transistor Q2 is in an OFF state, no current flows between the collector and the emitter of the transistor Q2.
That is, the circuit including the second power supply voltage applying unit 700B, the resistor R3, the resistor R2, and the transistor Q2 is disconnected at the collector of the transistor Q2, and includes the second power supply voltage applying unit 700B, the resistor R3, the resistor R2, and the transistor Q2. No current flows in the circuit.

  On the other hand, in the circuit composed of the second power supply voltage applying means 700B, the resistor R3, and the gate and source of the FET Q1, a voltage lower than the power supply voltage (18V) dropped by the resistor R3 is applied to the gate of the FET Q1. Since the voltage difference between the gate and the source of the FET Q1 does not exceed the threshold value (threshold voltage), the current due to the power supply voltage (18 V) applied to the source of the FET Q1 does not flow from the drain.

  As can be seen from the above description and the time chart of FIG. 6, during the normal operation (descent operation) of the first movable body B1, the voltage switching control unit 600 functions as described above, so that the second power supply The second voltage VM2 from the voltage applying unit 700B is not applied to the stepping motor M1 side, and the stepping motor M1 is accelerated and steady by the first power supply voltage VM1 applied from the first power supply voltage 700A. Then, it will stop through the deceleration area.

On the other hand, during the ascending operation of the first movable body B1, a voltage conversion signal is output from the movable body control unit 200D, whereby the voltage switching signal is maintained at the Hi level (+5 V), and a predetermined operation for operating the transistor Q2 is performed. The voltage signal is applied to the base side, and the transistor Q2 is turned on.
When the transistor Q2 is ON, the current flowing through the resistor R2 flows between the collector and the emitter of the transistor Q2, and the circuit including the second power supply voltage applying unit 700B, the resistor R3, the resistor R2, and the transistor Q2 A current controlled by a voltage signal applied to the base of the transistor Q2 flows.

Along with this, the voltage drop at the resistor R3 increases, and the voltage applied to the gate of the FET Q1 becomes smaller than the voltage when the transistor Q2 is OFF, and the reverse bias between the gate and the source in the FET Q1. As the voltage increases, a current due to the second power supply voltage 18V flows between the source and drain of the FET Q1.
That is, when the voltage switching signal is output from the port P1 of the driver board 500 and the transistor Q2 is turned on, the current generated by the voltage (18V) from the second power supply voltage applying unit 700B passes through the diode D2 and the stepping motor. Supplied to M1.

  As can be seen from the above description and the time chart of FIG. 6, the voltage switching control unit 600 functions as described above during the ascending operation of the first movable body B1, so that the second power supply voltage application unit 700B Is applied to the motor M1 side, and the motor M1 is controlled by the second voltage VM2 (18V) higher than the first voltage VM1 (12V) applied from the first power supply voltage applying means 700A. Become.

  Then, the driving torque during the ascending operation can be obtained substantially the same as or more than the driving torque during the descending operation by switching the power supply voltage to the second power supply voltage applying means 700B. It is possible to reliably prevent the operation of the first movable body B1 from becoming unstable due to a step-out caused by insufficient torque at the time of rising operation.

FIG. 7 shows a motor M2 assuming that the second movable body B2 stops in the middle from the fully open position to the fully closed position, performs a vibration operation at the stop position, and then further moves to the fully closed position. Is a time chart schematically showing a rotation speed (pps), a power supply switching signal (V), and a pulse voltage (V). As can be seen from the time chart of FIG. 7, during the vibration operation of the second movable body B2, the voltage switching control unit 600 functions as described above, whereby the voltage from the second power supply voltage applying unit 700B is changed to the motor M2; The motor M2; M3 is controlled by a voltage (18V) higher than the voltage applied from the first power supply voltage applying means 700A.
Then, the driving torque during the vibration operation can be obtained as a torque substantially equal to or higher than the driving torque during the closing operation by switching the power supply voltage to the second power supply voltage applying means 700B. In particular, it is possible to reliably prevent the operation of the second movable body B2 from becoming unstable due to a step-out caused by insufficient torque at the time of vibration operation.
That is, the driving torques (power supply voltages) of the motors M1; M2; M3 can be switched according to the operation patterns of the corresponding first movable body B1 and second movable body B2, respectively. The applied power supply voltage (12 V or 18 V) is switched by outputting a voltage conversion signal according to the operation pattern from the 200 movable body control unit 200D.

Next, the operation on the power supply voltage monitor unit 800 side when the power supply voltage is switched to the motors M1; M2; M3 as described above will be described. When the power supply voltage (12 V) of the first power supply voltage 700A is applied to the stepping motors M1; M2; M3, a predetermined power supply voltage is also applied to the power supply voltage monitor unit 800 via the power supply line 801. However, due to the presence of the Zener diode ZD1, no current flows through the LED 1, and the LED 1 does not emit light.
That is, the breakdown voltage of the Zener diode ZD1 is set to a voltage (for example, 13V) higher than the power supply voltage (12V) applied by the first power supply voltage 700A, and a voltage less than the breakdown voltage is the cathode of the Zener diode ZD1. Even when applied to the anode side, no current is output from the anode side, and the LED 1 connected to the anode side does not emit light.

On the other hand, when the power supply voltage (18V) of the second power supply voltage 700B is applied to the stepping motors M1; M2; M3 by switching the power supply voltage, a zener diode is connected to the power supply voltage monitor unit 800 via the power supply line 801. A voltage equal to or higher than the breakdown voltage of ZD1 is applied, a current flows through LED1, and LED1 emits light.
That is, the breakdown voltage of the Zener diode ZD1 is set to a voltage (13V) lower than the power supply voltage (18V) applied by the second power supply voltage 700B, and a voltage higher than the breakdown voltage is the cathode side of the Zener diode ZD1. Is applied to the anode side of the LED 1 from the anode side, and the LED 1 emits light by the current input from the anode side.
That is, the LED 1 has a higher breakdown voltage than the power supply voltage (12V) applied by the first power supply voltage application unit 700A and lower than the voltage (18V) applied by the second power supply voltage application unit 700B. Connected in series, light is emitted only when a reverse bias voltage equal to or higher than the breakdown voltage (13 V) is applied to the cathode side of the Zener diode ZD1, and the second power supply is confirmed by confirming the light emission of the LED1. It can be grasped that the power supply voltage of the voltage applying means 700B is appropriately applied to the motors M1; M2; M3.
In other words, by confirming the light emission of the LED 1, it is confirmed that the operation of the first movable body B1 and the second movable body B2 can be smoothly performed by the voltage application of the second power supply voltage application means 700B. be able to.
In the driving of the motors M1; M2; M3 according to the present embodiment, driving by applying a low voltage (12V) is set to a default (standard) value, so that at least driving by applying a low voltage is ensured as long as the motor is driven. Will be. However, in order to confirm whether or not the motor is driven at a high voltage (18V), some means is required. Therefore, in the present embodiment, driving by the high voltage (18 V) is confirmed by confirming the light emission of the LED 1 of the power supply voltage monitoring unit 800.
In order to easily check the light emission of the LED 1, it is desirable that at least the LED 1 constituting the power supply voltage monitor unit 800 is provided at a position visible from the outside on the back side of the game board 30. By providing in such a position, it is possible to easily perform a check such as an energization inspection in the manufacturing process and a visual check by a game shop employee after the game shop is installed.

Hereinafter, the hardware configuration of the main control device 100 and the sub control device 200 will be described with reference to FIG. 8, and the flow of games in the pachinko machine 1 will be described.
As shown in the figure, the main controller 100 includes a special symbol use lottery means 110, a hit type determination means 120, a variation display control means 130, a normal symbol use lottery means 150, a special game control means 160, and an electric tulip control. Means 170 and gaming state control means 180 are provided.

  The special symbol success / failure lottery means 110 executes a special symbol lottery (the first special symbol lottery or the second special symbol lottery) in response to the winning of the game ball in the first starting winning port 61 or the second starting winning port 62. Then, “win” or “miss” is electronically determined. Specifically, the special symbol success / failure lottery means 110 updates the value of the loop counter one by one within a predetermined range (an integer range of 0 to 65535 in the present embodiment) based on an interrupt signal periodically input. The game ball detection signal from the first start winning port detection sensor 91 or the second start winning port detection sensor 92 is input to the main control device 100 from a random number generating means for generating a random number for determining whether or not it is a hardware random number. Based on the result, a random number for determination of success / failure is acquired (latched).

Also, the special symbol success / failure lottery means 110 determines whether the acquired success / failure determination random number is a random number corresponding to “win” or “random” by referring to the special symbol lottery table. To do. The special drawing lottery table is data that defines a correspondence relationship between the random number for determination of success / failure and “winning” and “losing”. There are two types of special figure lottery tables: a special figure low probability lottery table and a special figure high probability lottery table. It is associated in advance, and “losing” is associated in advance with the random numbers 187 to 65535 for determination of success / failure. That is, the probability of winning is about 1/350.
On the other hand, in the special figure high-precision lottery table, for example, “winning” is associated in advance with random numbers 0-1860 for determination of success / failure, and “losing” is previously associated with random numbers for determination of success / failure 1861-65535. .
That is, the probability of winning when the special figure high-precision lottery table is referenced is about 1/35. As can be seen by comparing these winning probabilities, the winning probability of “hit” according to the special figure high-accuracy determination table is about 10 times higher than the probability of winning “win” according to the special figure low-accuracy determination table. high.
The gaming state in which the special figure low probability lottery table 110 is referred to by the special symbol success / failure lottery means 110 and “winning” or “losing” is determined is a special figure low probability state. The gaming state in which “win” or “losing” is used is a special figure high probability state (so-called probabilistic gaming state).
Hereinafter, for the sake of convenience, the “special figure low probability state” may be referred to as “special figure low probability”, and the “special figure high probability state” may be referred to as “special figure high probability” or “probability change game”. The switching between the special figure low probability or the special figure high probability is executed by a gaming state control means 180 described later.

  The special symbol success / failure lottery means 110 further determines whether the first special symbol or the second special symbol is changed based on the winning of the game ball in the first starting winning port 61 or the second starting winning port 62. The random number holding means for determining whether or not to determine is stored using the RAM of the main controller 100 up to a predetermined upper limit number as reserved ball random numbers related to the first special symbol or the second special symbol. The upper limit of the random numbers that can be stored on hold is, for example, four winning / notifying determination random numbers acquired when winning at the first starting winning opening 61, and whether or not the winning determination is acquired when winning at the second starting winning opening 62 For example, when the total number of random numbers for use is up to eight, for example, the number of winning / failure determination random numbers already stored on the basis of winning in the first starting winning opening 61 is the upper limit of four, the first starting winning opening When winning at 61, the random number for success / failure determination is not further acquired, and the same applies to the second start winning opening 62.

In addition, when the result of the special drawing lottery (the first special drawing lottery or the second special drawing lottery) is “winning”, the winning type determining means 120 sets the type of “winning” (special symbol type) to electronic Determined by lottery. Specifically, the hit type determination means 120 updates the value of the loop counter one by one within a predetermined range (in this embodiment, an integer range of 0 to 99) based on an interrupt signal that is periodically input. A game ball detection signal from the first start winning port detecting sensor 91 or the second starting winning port detecting sensor 92 is input to the main controller 100 from a random number generating means for generating a hit type determining random number which is a hardware random number. Based on this, a random number for hit type determination is acquired (latched). Further, the hit type determining means 120 determines the hit type based on the acquired hit type determining random number with reference to the first special figure type table or the second special figure type table.
In the hit type table, for example, four types of hits, 16R special symbol A, 16R special symbol B, 6R special symbol A, 6R special symbol B, are defined, and 1 corresponding to each hit type. Specific aspects of special symbols up to 9 are specified.

  “16R” and “6R” attached to each hit type are abbreviations of “16 rounds” and “6 rounds”, respectively, and are the maximum number of rounds of the big hit game preliminarily associated with each hit type. is there. That is, after the result of the special drawing lottery is “winning”, the winning type is determined as one of the above winning types, and the first special symbol or the second special symbol is stopped and displayed, special game control means described later According to 160, a round jackpot game associated with each hit type is executed.

  The winning type determination means 120 is for determining the winning type obtained based on the winning of the game ball at the first starting winning port 61 or the second starting winning port 62 during the variation of the first special symbol or the second special symbol. There is provided a hit type determining random number holding means for storing random numbers up to a predetermined upper limit number as reserved ball random numbers related to the first special symbol or the second special symbol, using the RAM of the main controller 100. The function of the hit type determination random number holding means is the same as the function of the above-described success / failure determination random number holding means, and the description thereof will be omitted.

As described above, the special symbol success / failure lottery means 110 and the winning type determination means 120 each receive a random number for winning / failure determination and a winning when the game ball has won the first starting winning opening 61 or the second starting winning opening 62, respectively. When a random number for type determination is obtained, and a special drawing lottery related to the success / failure is performed based on the arrival of a predetermined opportunity, and when the special drawing lottery is won (when the result of the special drawing lottery is “win”) And a function of determining one hit type from a plurality of hit types.
Here, the predetermined opportunity is a case where the first special symbol and the second special symbol are not changing and the jackpot game is not being played. For example, the current gaming state is not a jackpot game. If the first special symbol or the second special symbol is fluctuating at the time of holding the random number for determining whether or not to win and the random number for determining the hit type, the fluctuation time of the first special symbol or the second special symbol in the fluctuation has passed, After stopping in a predetermined manner, the above processing is executed sequentially.
The order in which the above-described success / failure determination process and the hit type determination process that is executed subsequent to the above-described process is performed is the order of winning the first start winning opening 61 or the second starting winning opening 62, in other words, in the RAM. The determination may be executed in the order in which they are stored. For example, the determination process and the winning type determination process related to the random number for determination of success / failure acquired by winning one of the second start winning openings 62 may be executed with priority. It may be.

  Next, the fluctuation display control means 130 shown in FIG. 8 will be described. The variation display control means 130 determines the variation times of the first special symbol and the second special symbol from among a plurality of variation times by electronic lottery. Further, the variation time of the first special symbol and the second special symbol is also used as the variation time of the effect symbol S. That is, the variation time of the special symbol and the variation time of the effect symbol S are synchronized. In the following, a special symbol variation time determination process by the variation display control means 130 will be outlined.

  The fluctuation display control means 130 is a software random number by updating the value of the loop counter one by one within a predetermined range (in this embodiment, an integer range of 0 to 99) based on an interrupt signal periodically input. A special figure variation pattern random number generating means for generating a special figure variation pattern random number and a winning of a game ball in the first start prize opening 61 or the second start prize opening 62 (first start prize opening detection sensor) 91 (based on the fact that a game ball detection signal from the second start winning award detection sensor 92 is input to the main control device 100), obtains (latches) a special figure fluctuation pattern random number generated by the special figure fluctuation pattern random number generating means. ) Special figure fluctuation pattern random number acquisition means, and a plurality of special characteristics in which fluctuation times corresponding to the special figure fluctuation pattern random number acquisition means acquired by the special figure fluctuation pattern random number acquisition means are defined. And a change pattern table.

The special figure variation pattern table is subdivided into a table for non-temporal shortening (common figure low accuracy) or a time reduction (common figure high accuracy) table. Is further subdivided into hits and misses.
In these special figure fluctuation pattern tables, for example, different fluctuation times such as “4 seconds”, “12 seconds”, “30 seconds”, “45”, “60 seconds”, etc. are defined. Therefore, the selection rate of the variable time is different.
Note that the types of special figure variation pattern tables are not limited to those described above. For example, a table that is referenced when the number of reserved determination random numbers stored is 3, a table that is referenced when there are four, and the like. And the variation time until the first special symbol or the second special symbol is derived and displayed with an increase in the number of reserved memories may be gradually shortened.
In the present embodiment, the game to which the special time variation pattern table for non-time reduction is referred is a non-time saving game, and the game to which the special time variation pattern table for time reduction is referred is a time reduction game. Further, switching of these game states is executed by a game state control means 180 described later.

  The fluctuation display control means 130 further has a special figure fluctuation pattern random number holding means, and a game ball to the first start winning opening 61 or the second start winning opening 62 during the fluctuation of the first special symbol or the second special symbol. When the special figure fluctuation pattern random number obtaining means obtains the special figure fluctuation pattern random number based on the winning, the random number is individually stored using the RAM of the main controller 100 up to a predetermined upper limit number. Note that the upper limit of the special figure variation pattern random numbers that can be stored on hold is the same as the upper limit of the above-described success / failure determination random numbers and the hit type random numbers. That is, the special figure variation pattern random number is a random number acquired together with the above-mentioned special figure success / failure determination random number and the hit type determination random number when the first start winning opening 61 or the second start winning opening 62 is won. .

  The fluctuation display control means 130 selects one special figure variation pattern table from a plurality of special figure fluctuation pattern tables based on the current game state (non-short-time game or short-time game) and the result of special drawing lottery ("winning" or "losing"). Referring to the figure fluctuation pattern table, one fluctuation time corresponding to the special figure fluctuation pattern random number is determined as the fluctuation time of the special symbol.

Further, the fluctuation display control means 130 controls the first special symbol display device 35A or the second special symbol display device 35B based on the decided fluctuation time. Specifically, the fluctuation start signal is output to the first special symbol display device 35A or the second special symbol display device 35B, and time measurement by an unillustrated timer is started, and the extracted fluctuation time has elapsed. Based on the above, a variation stop signal including the type of the special symbol is output to the first special symbol display device 35A or the second special symbol display device 35B.
The first special symbol display device 35A or the second special symbol display device 35B has a special symbol mode (1 corresponding to the hit type determined by the hit type determining means 120 for the special symbol being changed by the input of the change stop signal. To 9) or a special symbol form ("-") indicating a loss.
In addition, the fluctuation display control means 130 outputs an effect symbol change command and an effect to the sub-control device 200 together with the output of the change start signal for starting the change of the special symbol and the change stop signal for stopping the change of the special symbol. Send a symbol stop command. Thereby, the change and stop of the special symbol and the change and stop of the effect symbol S are performed in synchronization.

  The normal symbol success / failure lottery means 150 shown in FIG. 8 determines “winning” or “losing” by electronic lottery (ordinary lottery) when a game ball passes through the through chucker 66. Specifically, the normal symbol success / failure lottery means 150 is configured in substantially the same manner as the special symbol success / failure lottery means 110 described above, and the normal symbol success / failure lottery means 150 is interrupted periodically. The game ball has passed through the through chucker 66 from the random number generating means for normal / unusable random numbers which is a software random number by updating the value of the loop counter one by one within a predetermined range based on the signal. In other words, on the basis of the game ball detection signal from the through-chucker detection sensor 94 being input to the main control device 100, a random number for normal / incorrect use is obtained (latched), and the random number for normal / incorrect use is obtained. It is determined with reference to the non-short-time determination table or the short-time determination table whether or not is a win.

  The non-time reduction determination table and the time reduction determination table prescribe the correspondence relationship between the random number for normal use / non-standard-use and “winning” and “losing”. The winning probability of “win” based on the determination table is set to 1/120, for example, and the winning probability of “win” based on the determination table for time reduction is set to 1 / 1.1. In other words, the judgment table for time reduction is set so that the probability of winning “winning” is significantly higher than the judgment table for non-time reduction, and “winning” is won in most cases. It has become.

  In addition, when the normal symbol success / failure lottery means 150 obtains the normal symbol success / failure random number while the normal symbol is changing, the normal symbol success / failure random number is normally reduced to a predetermined upper limit number (four in this embodiment). There is provided a random number holding means for normal / incorrect use for storing the reserved ball random numbers related to the symbols using the RAM of the main controller 100. Since the details of the random number holding means for normal / unusual are similar to the functions of the above-described random number holding means for determining whether or not, the description thereof will be omitted.

The electric tulip control means 170 shown in FIG. 8 energizes the electric tulip driving device 63 </ b> A of the electric tulip 63 when the “winning” is won in the normal drawing lottery by the normal symbol success / failure lottery means 150. The pair of blade members is opened and closed. This electric tulip control means 170 opens the electric tulip 63 twice in an opening time of 2.9 seconds, for example, for one “hit” in the short-time game, and for one “hit” in the non-time-short game. The electric tulip 63 is opened once with an opening time of 0.2 seconds. That is, during the short-time game, as described above, the “winning” is almost won by the electronic symbol lottery means 150 for the normal symbol, and the electric tulip 63 is opened twice in 2.9 seconds based on the winning. Therefore, if a player strikes a game ball on one side of the game area 31 of the game board 30, the game ball can be easily won at the second start winning opening 62, and as a result, during the short-time game, The game can be played with almost no reduction.
That is, the short-time game is a state in which the electric tulip 63 is easily opened, and the player can easily (support) winning the game ball to the second start winning opening 62 (so-called electric support state). . On the other hand, in the non-short-time game, it is difficult for the player to open the electric tulip 63, and it is difficult for the player to win the game ball in the second start winning opening 62.

  Returning to FIG. 8, the special game control means 160 will be described. When the result of the first special figure lottery or the second special figure lottery is a win, the special game control means 160 uses a plurality of release patterns (16R) or “6R” corresponding to the hit type to make the attacker device 65. In this embodiment, the release operation per round is either 25 seconds after the release or until nine game balls are won. It is set until an early condition is satisfied, and the opening operation is repeated 6 rounds or 16 rounds depending on the hit type.

Next, the gaming state control means 180 will be described. When the result of the first special drawing lottery or the second special drawing lottery is a win (per 1st special figure or 2nd special figure), the gaming state control means 180 determines the big hit game according to the hit type. Switch the later game state (combination of special figure low accuracy, special figure high accuracy, general figure low accuracy (non-short time), normal figure high accuracy (short time)).
For example, when the hit type is 16R special symbol A, the gaming state control means 180 switches the gaming state after the big hitting game to a gaming state of special figure high probability and normal figure high probability.
Further, in this case, the special figure high probability and the normal figure high probability game state after the winning game continues, for example, until the result of the next special figure lottery becomes a hit. In addition, it is good also as a structure which continues until a 1st special drawing lottery or a 2nd special drawing lottery is performed a predetermined number of times after completion | finish of a hit game, for example, either a special figure high probability and a common figure high probability.
When the hit type is 16R special symbol B, the gaming state control means 180 switches the gaming state after the big hit game to a gaming state with a special figure low probability and a normal figure high probability. Further, in this case, the general figure high accuracy after the winning game is continued from the end of the winning game until the first special drawing lottery or the second special drawing lottery is executed a predetermined number of times.
When the hit type is the 6R special symbol A, the gaming state control means 180 switches the gaming state after the big hit game to a gaming state with a special figure high probability and a normal figure low probability. In this case, the special figure high accuracy after the big hit game is continued until the result of the next special figure lottery becomes a win.
When the hit type is the 6R special symbol B, the gaming state control means 180 switches the gaming state after the big hit game to the gaming state of special figure high probability and normal figure high probability. Further, in this case, the special figure high accuracy and the general figure high accuracy after the big hit game are continued until the result of the next special drawing lottery becomes a win.
As described above, the gaming state control means 180 has a function of switching the gaming state after the big hit game according to the hit type. Specifically, by switching the gaming state flag provided in the storage area of the RAM. Control the gaming state.
In addition, the special symbol use lottery means 110, the hit type determination means 120, the variation display control means 130, and the normal symbol use lottery means 150 described above refer to the game state flag to determine each table corresponding to the game state. Refer to and execute the process.

Information extracted by the above-described main symbol determination process by the special symbol use lottery means 110 of the main control device 100, the hit type determination process by the hit type determination means 120, and the variation time determination process by the special symbol variation display control means 130 ( Lottery result (“Win”, “Loose”) information,
(The hit type information, the variation time information) is transmitted to the sub-control device 200 side as an effect symbol variation command including the information, and the sub-control device 200 that has received the command is connected to the output side via an interface outside the figure. The speaker 8, the plurality of light emitting units 10A, the effect symbol display device 50, the first movable body B1, and the second movable body B2 are controlled.

  In addition, the main controller 100 determines that the special symbol lottery result is “winning”, and after the first special symbol or the second special symbol is stopped and displayed in a manner indicating that the result is the winning symbol, Is transmitted to the sub-control device 200 side, and a big hit effect is executed by each device connected to the output side. Hereinafter, the sub-control device 200 will be described.

The sub-control device 200 mainly includes an effect symbol control unit 200A that controls the effect symbol display device 50, a lamp control unit 200B that mainly controls the plurality of light emitting units 10A and 20A, and an acoustic control unit 200C that mainly controls the speaker 8. The movable body controller 200D controls the first movable body B1 and the second movable body B2.
Each control unit includes a CPU as a calculation unit, a ROM in which operation programs and drive data are stored, and a storage unit such as a RAM that can temporarily store data necessary for driving. Each control unit may be provided on a separate substrate or may be provided on a single substrate. Hereinafter, each control part which comprises the sub-control apparatus 200 is demonstrated.

The effect symbol control unit 200A controls the effect symbol display device 50 based on the effect symbol variation command transmitted from the main control device 100 side, displays the predetermined variation time and the effect symbol S in a variable manner, and the predetermined variation time has elapsed. The effect design S is stopped and displayed later.
More specifically, the effect symbol control unit 200A, based on the change time information included in the effect symbol change command, selects one change pattern from a plurality of change pattern tables defined for each change time information in the ROM. To decide. In the variation pattern table, a plurality of variation patterns corresponding to the variation pattern random number acquired by the effect symbol control unit 200A when the effect symbol variation command is received are defined, and the effect symbol control unit 200A follows the acquired variation pattern random number. Then, one variation pattern corresponding to the random number is determined.

  As the types of variation patterns, for example, normal variation (non-reach), reach variation (normal), reach variation (super 1), reach variation (super 2), reach variation (super 3), etc. have different times and production modes. A pattern is defined. “Reach” is a state in which two of the three symbols constituting the production symbol S are stopped in advance by the same number or character, and the remaining symbols are the same number as the two symbols in the reach state. Or, if you stop with a character, it means a big hit game.

In addition to the above-described determination of the variation pattern, the effect symbol control unit 200A also executes a notice pattern determination process and a stop symbol pattern determination process. Each of these processes is randomly determined by a random number acquired when the symbol variation command is received and a table in which a plurality of notice patterns and stop symbol patterns corresponding to the random number are defined. A control command including the variation pattern, the notice pattern, and the stop symbol pattern determined by the above process is transmitted to the effect symbol display device 50, and various effects are displayed on the effect symbol display device 50.
In addition, when the result of the 1st special drawing lottery or the 2nd special drawing lottery mentioned above is a win, the aspect of the production symbol S that is finally derived and displayed is, for example, that numbers or characters are all the same numbers or characters. An aspect in the case of being in an aligned state and being lost is an aspect other than the above-described aspect. Further, the effect symbol control unit 200A causes the effect symbol display device 50 to display a specific special game effect during the jackpot game based on the reception of the jackpot effect command from the main control device 100.

  The lamp control unit 200B receives an internal command including a notice pattern and a variation pattern (hereinafter, sometimes referred to as an effect pattern) determined by the effect symbol control unit 200A and a jackpot effect command, and generates an effect based on the command. The light emitting units 10A and 20A are controlled in a manner corresponding to the pattern and the big hit game. Specifically, the lamp control unit 200B reads lighting data in which the lighting patterns of the light emitting units 10A and 20A are defined, and transmits the read data to the driver circuit of the light emitting units 10A and 20A. Each driver circuit that has received the lighting data controls the LED group constituting the light emitting unit 10A; 20A according to the lighting data according to a predetermined pattern, so that the effect pattern during the change display of the effect symbol S and after the change stop The lighting (flashing) operation corresponding to the big hit game is executed.

  The voice control unit 200C receives the internal command including the effect pattern determined by the effect symbol control unit 200A and the big hit effect command, and based on the command, the change of the effect symbol S from the ROM outside the figure or the big hit game The music data and sound data that excite the game are output to the speaker 8 side. A driver circuit that directly controls the speaker 8 drives the speaker 8 based on the various data described above.

The movable body control unit 200D receives an internal command including an effect pattern determined by the effect symbol control unit 200A, and controls the first movable body B1 and the second movable body B2 simultaneously or individually based on the command.
Specifically, the movable body control unit 200D defines first drive data 200a in which data of a plurality of drive patterns of the motor M1 is defined and stored, and data of a plurality of drive patterns of the motors M2 and M3. And the second drive data 200b stored therein, and the drive data 200a, in which the data of the corresponding drive pattern is stored in accordance with the type of the notice pattern and the variation pattern determined in advance by the effect symbol control unit 200A, 200b is read and the drive data is output to the driver board 500 described above.

As a plurality of driving patterns defined in the first driving data 200a, a driving pattern (12V driving) for moving the first movable body B1 from the rising limit position which is the initial position (fixed position) to the lowering limit position, or a lowering limit. In addition to the drive pattern (18V drive) for moving the first movable body B1 at the position to the ascending limit position, for example, the first movable body B1 is supplied with the first power supply voltage (12V) at the start of the fluctuation of the above-described effect symbol S. Is lowered to an intermediate position in the up and down direction, and after a certain stop time, the second power supply voltage (18V) raises it again to the rising limit position, or the second power supply voltage (18V) is used to drive it. In the above-described production symbol control unit 200A, such as a big hit suggestion drive that suddenly descends from the ascending limit position to the descending limit position during the fluctuation of the time, and then rapidly rises again to the ascending limit position after a lapse of a predetermined time. There are various driving patterns corresponding to the determined notice pattern and the variation pattern, and the movable body control unit 200D reads the drive data in which the determined notice pattern and the variation pattern and the corresponding drive pattern are defined, and the driver Output to the substrate 500.
In the case of a pattern in which the drive pattern drops rapidly, when the load on the first movable body B1 is light, a conventional low voltage (12 V) is used and driving corresponding to increasing the number of pulses per unit time is possible.

The plurality of drive patterns defined in the second drive data 200b include a drive pattern (12V) for moving the second movable body B2 from the fully open position, which is its initial position (fixed position), to the fully closed position, and the fully closed position. In addition to the drive pattern (12V) for moving the second movable body B2 to the fully open position, for example, the second movable body B2 is driven with the second power supply voltage (18V) at the start of the fluctuation of the above-described effect symbol S. The notice drive 1 that vibrates at the fully open position, the notice drive 2 that vibrates at the intermediate position in the opening and closing direction, the notice drive 3 that vibrates at the fully closed position, or the fully open position from the fully open position during the change of the production symbol S As in the case of the first drive data 200a described above, the effect symbol control unit such as the jackpot suggestion drive that suddenly closes until a predetermined time elapses and then suddenly opens again to the fully open position again after a predetermined time. There are various driving patterns corresponding to the warning pattern and the variation pattern determined by 00A, and the movable body control unit 200D reads the driving data in which the driving pattern corresponding to the determined warning pattern and the variation pattern is defined, Output to the driver board 500.
In addition, when the driving pattern performs a sudden closing operation and a sudden opening operation, and the load of the second movable body B2 is light, driving is performed by using the conventional low voltage (12 V) and increasing the number of pulses per unit time. Correspondence is also possible.

  Further, the movable body control unit 200D outputs a voltage conversion signal to the driver board 500 at a predetermined time based on the type of the read drive data, and increases the drive torque of the motors M1; M2; M3. Here, for example, when an operation pattern in which the first movable body B1 suddenly descends from the ascending limit position to the descending limit position and rapidly ascends again after a certain period of time is assumed, for example, the motor M1 It is assumed that the voltage conversion signal is output to the driver board 500 simultaneously with the beginning of the reverse rotation step. When individual drive data is output corresponding to the descending operation and the ascending operation, the voltage conversion signal may be output to the driver board 500 simultaneously with the output of the drive data for executing the ascending operation. The predetermined time is the same for the second movable body B2, and the voltage conversion signal may be output to the driver board 500 simultaneously with the start of the operation requiring the driving torque (vibration operation).

The driver board 500 outputs a pulse signal from each port in a predetermined order based on the drive data output from the movable body controller 200D, and the motor M1; M2; M3 is driven at a predetermined drive voltage of 12V in a normal case. Drive by pattern. Further, the driver board 500 outputs a Hi level signal (voltage switching signal) from the port P1 based on the voltage conversion signal output from the movable body control unit 200D at a predetermined time based on the driving pattern data, and the motor M1; M2: The power supply voltage applied to M3 is switched to the voltage (18V) applied by the second power supply voltage applying means 700B.
That is, the movable body control unit 200D outputs drive data corresponding to the type of effect pattern to the driver board 500 side, and normally drives the motors M1; M2; M3 with a predetermined drive pattern of the drive voltage 12V. As a result, when the first movable body B1 and the second movable body B2 using the motors M1; M2; M3 as drive sources are operated according to a predetermined operation pattern, and driven according to the content of the drive data. In this case, a voltage conversion signal is output to the driver board 500 to switch the applied voltage of the motors M1; M2; M3 to a high voltage to execute a process for securing a torque margin.
Further, when a high voltage (18V) is applied to the motors M1; M2; M3 by the second power supply voltage applying means 700B, the power supply voltage monitoring unit 800 operates and the power supply voltage monitoring unit Since the LED 1 constituting 800 emits light, the power supply voltage switching unit 600 appropriately switches the power supply voltage by confirming the light emission, and the two power supply voltage applying means 700B is applied to the motors M1; M2; M3.
