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, there is a concern that the motor M1 in the present embodiment has insufficient torque due to its operation pattern (ascending operation), and first power supply voltage applying means having different voltages from each other in order to compensate for the torque shortage during the operation pattern. 700A and the power supply voltage from the 2nd power supply voltage application means 700B are comprised so that input is possible, and it is a circuit structure by which operation | movement of 1st movable body B1 at the time of raise operation | movement 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 pulse signals φ1 to φ4 for controlling the motor M1. And a port P1 that can output a voltage switching signal (Hi level) in accordance with a voltage conversion signal from the movable body control unit 200D. 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 voltage switching control unit 600 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 signal 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 motor M1 via the power supply switching control unit 600 is a power supply circuit or power supply element that constantly applies a predetermined power supply voltage (18V) to the power supply switching control unit 600 and the stepping motor M1 side. Consists of. The power supply voltage applied by the second power supply voltage applying means 700B is set higher than the power supply voltage applied by the first power supply voltage applying means 700A described later, and the voltage is within the allowable range of the heat generation temperature of the motor M1. If there is, it can be set freely.

On the other hand, the first power supply voltage applying means 700A is connected to the motor M1 side via the power supply line 701, similarly to 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 constituted by a power supply circuit or a power supply element that constantly applies a predetermined first power supply voltage VM1 (12V) to the motor M1 side, and torque shortage is assumed due to the operation pattern of the first movable body B1. During an operation that is not performed (during a lowering operation or the like), a power supply voltage (normal voltage) of 12 V is supplied to the motor M1 side. On the other hand, during an operation in which torque shortage is assumed by the operation pattern of the first movable body B1 (for example, during an ascending operation), the 18 V second power supply voltage VM2 having a voltage higher than the normal voltage is supplied. Hereinafter, the flow during power supply voltage switching will be described with reference to FIG.

As described above, during the normal operation of the first movable body B1, the voltage switching signal is maintained at the low level (0 V), and the predetermined voltage for turning on the transistor Q2 is not applied to the base side. Is in an OFF state. When the transistor Q2 is OFF, the current flowing from the second voltage VM2 applied by 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 has an acceleration region and a steady state by the first voltage VM1 applied from the first power supply voltage applying unit 700A. It will stop through the area and deceleration area.

On the other hand, during the raising operation of the first movable body B1, the voltage switching signal is maintained at the Hi level (+ 5V), a predetermined voltage signal for operating the transistor Q2 is applied to the base side, and the transistor Q2 is in the ON state. Is done.
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 of the second voltage VM2 (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 driven by the second voltage VM2 (18V), which is higher than the first voltage VM1 (12V) applied from the first power supply voltage applying means 700A. Then, it will stop through the deceleration area.
The driving torque during the ascending operation can be obtained by switching the power supply voltage to the second power supply voltage applying means 700B, so that substantially the same torque as the driving torque during the descending operation can be obtained. 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 in the acceleration region.

On the other hand, the voltage application means 810 of the motors M2 and M3 is controlled by a drive circuit in which the second power supply voltage application means 700B and the voltage switching control unit 600 are not present, as shown in FIG. The opening operation and the closing operation of B2 are realized by the rotation of the motors M2 and M3 driven by the voltage applied from the first power supply voltage applying unit 700A that outputs the power supply voltage of 12V.
The other circuit configuration is the same as the circuit configuration in the motor M1 described above, and a description thereof will be omitted.

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 “hit” 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 input of the game ball detection signal from the through chucker detection sensor 95 to the main control device 100, a random number for normal-use / non-use is acquired (latched), and the acquired random number for normal-use / non-use 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-mentioned main symbol control unit 100 for determining whether or not to win / fail by the special symbol determination lottery means 110, winning type determination processing by the hitting type determination means 120, and variation time determination processing by the special symbol variation display means 130 (whether or not The lottery result (“winning”, “losing”) information, winning type information, and variation time information) is transmitted to the sub-control device 200 as an effect symbol variation command including the information, and the sub-control device 200 that has received the command. Controls 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 connected to the output side via an interface not shown.

  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.
