Description

  The present invention relates to a pachinko machine installed in a game hall such as a pachinko parlor.

The pachinko machine is provided with a display means such as a liquid crystal display that displays a variation of the symbol. In addition, in the pachinko machine, an effect that enhances the fun of the game is performed by moving the movable member in conjunction with the change display of the symbols. In a pachinko machine equipped with a movable member, for example, the movable member is moved by transmitting a driving force supplied from a motor, a solenoid, or the like to the movable member via a driving force transmission mechanism including a gear or a cam. . In addition, as described in Patent Document 1 below, the movable state of the movable member is backed up in the event of a power failure, and after the power is restored from the power failure, the movement of the movable member can be resumed from the state before the power failure. Some have done.

  By the way, in the pachinko machine, there is a problem that when the dust is mixed in the driving force transmission mechanism, for example, when the dust is caught between the gears, the movable member cannot move to a predetermined position. . Such a problem is often solved by moving the movable member in the direction opposite to the direction toward the planned position. For this reason, for example, when the power is turned on (when the power is turned on), it is set so that the movable member sequentially moves to all movable positions, and the power is turned off if a malfunction occurs in the movable part during play. Then, it may be possible to recover from the problem by turning on the power again.

  However, in this case, every time a malfunction occurs, there is a problem that it takes time and effort because the store clerk of the pachinko store needs to turn on the power again. Also, until the power is turned off, the pachinko machine tries to move the movable member to the planned position (to continue to supply the driving force from the motor, etc.), so the motor and the driving force transmission mechanism are loaded. There is also a problem that is damaged.

  The present invention has been made in view of the above background, and provides a pachinko machine that can be easily recovered from a failure and can reduce the load on a motor, a driving force transmission mechanism, and the like even if the failure occurs. The purpose is that.

  In order to achieve the above object, the pachinko machine of the present invention is provided with a start winning opening for receiving a game ball and a display means for displaying a variation of a symbol on a game board on which a game ball is launched. A lottery is performed in response to the winning of the ball or a determination is made to lose, and the symbols are displayed in a variation manner determined based on the lottery result, and are arranged in the vicinity of the display means, including the initial position. When the movable member movable to a plurality of positions and the determined variation display mode are the predetermined modes, the driving force is applied to the movable member so as to return to the initial position after moving along a preset movement path. In a game machine equipped with effect drive execution means for providing effect drive, when the power of the game machine is turned on, it moves so that it can move to all possible positions and then return to the initial position. An initial drive execution means for performing an initial drive for supplying a driving force to the material; and a check signal output means for outputting a check signal after the symbol variation display is completed when the determined variation display mode is a predetermined mode; When the check signal is output, the position of the movable member is detected by a plurality of sensors arranged on the moving path of the movable member. If the movable member is not detected at the initial position, the movable member returns to the initial position. The correction drive execution means for performing the correction drive for supplying the driving force to the member, and the movable member is not detected continuously a plurality of times at any one position among the plurality of positions set as the movement destination during the effect driving. If the movable member is not detected at any of a plurality of positions set as the movement destination during the initial drive, or after the correction drive, the movable member is moved to the initial position. If not known, an error signal output means for outputting an error signal, a drive control means for stopping the supply of driving force to the movable member when the error signal is output, and after the error signal is output And an error return means for canceling the supply stop of the driving force to the movable member and executing the initial driving when the check signal is received after a predetermined time has elapsed.

  The error return means preferably executes the initial operation within an interval time from the end of the symbol variation to the start of the next symbol variation.

  In addition, it is preferable to provide notification means for notifying this when the drive control means stops supplying the driving force to the movable member and when the error recovery means performs initial drive.

  The pachinko machine of the present invention stops the supply of the driving force to the movable part when a problem such that the movable member cannot move to a predetermined position occurs. The load on the driving force transmission mechanism can be reduced. In addition, after the predetermined time has elapsed since the occurrence of the defect, when the symbol variation display is completed, the initial drive is automatically performed, so that the defect can be easily recovered.

  Furthermore, during the effect driving, when the movable member is not detected continuously several times at any one position among the plurality of positions set as the movement destination, it is recognized as a malfunction (error). Despite the accidental temporary failure, the supply of the driving force to the movable member is not stopped.

  1 and 2, the pachinko machine 10 includes a game board 12. A transparent glass plate is disposed in front of the game board 12, and a game area 14 is formed between the game board 12 and the glass plate. Then, the game balls launched in response to the player's launch operation flow down the game area 14. In the game area 14, a start winning opening 16 and a center accessory 18 are provided. When a game ball wins the start winning opening 16, a predetermined number of game balls are paid out as a winning ball, and a winning lottery for determining winning or losing is performed.

  The center accessory 18 is provided with a liquid crystal display (display means) 20, a rotating accessory 22, and a swinging accessory (movable member) 24. The liquid crystal display 20 has three regions, a left region, a right region, and a middle region. When a game ball wins at the start winning opening 16, after the above-described winning lottery is performed, a variable display of symbols composed of numbers 0 to 9, for example, is started in each area. In the symbol variation display, for example, the symbols are scrolled from top to bottom. Then, once the symbols are stopped and displayed in all the areas, the one-time variation display is completed.

  If the same type of symbols are available when the variable display is finished, the other combinations are lost. When winning, the normal mode is changed to the winning mode and the attacker 26 is opened. When the attacker 26 is opened, the big prize opening is exposed, and a game ball can be won in the big prize opening. The attacker 26 is closed when a predetermined number (for example, 10) of game balls wins the big winning opening or when the opening time of the big winning opening becomes 30 seconds, for example. In the hit mode, such opening / closing of the attacker 26 is executed 15 times, for example.

  The rotating combination 22 and the swinging combination 24 are provided to produce a game, and are driven in conjunction with, for example, a change display of symbols. The rotating accessory 22 is formed in a disk shape, is housed in the cover 28, and is disposed on the upper right side of the liquid crystal display 20. The rotating combination 22 has “gold” written on its surface. In addition, the rotary accessory 22 is provided with a rotary shaft 30 perpendicular to the game board 12 at the center of the board surface, and is rotatably held around the rotary shaft 30. The rotating combination 22 is driven and rotated by a stepping motor or the like.

  The swinging combination 24 is formed to imitate a cherry branch and is arranged on the right side of the liquid crystal display 20. The swinging accessory 24 is provided with a swinging shaft 32 perpendicular to the game board 12 at the base of the cherry branch, and the initial position (with the swinging shaft 32 covering the rotating accessory 22 ( 1) and a lower position covering the liquid crystal display 20 (see FIG. 2). The swinging accessory 24 is normally held at an initial position, and swings in conjunction with a symbol change display.

  As shown in FIG. 3, a gear 34 is integrally formed on the swinging accessory 24 on the side opposite to the cherry blossom portion with the swinging shaft 32 interposed therebetween. Further, a first stopper 36, a second stopper 38, a gear 40, a first sensor 42, and a second sensor 44 are provided in the vicinity of the gear 34. The first stopper 36 is provided below the gear 34 so that the swinging accessory 24 comes into contact with the lower surface of the gear 34 when the swinging accessory 24 moves to the initial position. It is provided above the gear 34 so as to come into contact with the upper surface of the gear 34 when moved to the position. As described above, the swinging range of the swinging combination 24 is restricted between the initial position and the lower position by the first and second stoppers 36 and 38.

  The gear 40 is meshed with the tooth row 34 a of the gear 34. The gear 40 is directly connected to the stepping motor 46 and rotates with the rotation of the stepping motor 46. A motor driver 48 is connected to the stepping motor 46, and the stepping motor 46 rotates forward by an amount corresponding to the number of drive pulses supplied from the motor driver 48 (in FIG. 3, the gear 40 is rotated clockwise). In the direction of rotation) or reverse rotation (in FIG. 3, the gear 40 is rotated in the direction of rotating counterclockwise). The swinging accessory 24 swings when the driving force supplied from the stepping motor 46 is transmitted to the gear 34 via the gear 40. In this embodiment, by supplying 50 forward rotation pulses, the stepping motor 46 rotates forward, the swinging accessory 24 moves from the initial position to the lower position, and 50 reverse rotation pulses. An example will be described in which the stepping motor 46 rotates in reverse by being supplied and the swinging accessory 24 moves from the lower position to the initial position.

  A notch 50 is formed on the back surface of the gear 34, and the first sensor 42 is disposed at a position facing the notch 50 when the swinging accessory 24 moves to the initial position. The second sensor 44 is disposed at a position facing the notch 50 when the swinging accessory 24 moves to the lower position. Each of the first and second sensors 42 and 44 is composed of, for example, an infrared sensor, and detects this when it faces the notch 50 and outputs a detection signal. That is, when the swinging accessory 24 moves to the initial position, a detection signal is output from the first sensor 42, and when the swinging accessory 24 moves to the lower position, a detection signal is output from the second sensor 44. Is done.

  In FIG. 4, the operation of the pachinko machine 10 is controlled by the main control board 60. The main control board 60 includes a main CPU 62 and a main memory 64 in which a control program and various setting information are stored. The main CPU 62 controls the entire main control board 60 based on information stored in the main memory 64. The main memory 64 is also used for temporary storage of data relating to the game, such as a flag indicating the winning lottery result.

  A start winning opening sensor 66 is connected to the main CPU 62. The main CPU 62 is provided with a winning lottery unit 68, a stop symbol determining unit 70, and a variation pattern lottery unit 72. The start winning port sensor 66 detects that a game ball has entered the start winning port 16 and inputs a detection signal to the main CPU 62.

  The main CPU 62 operates the lottery unit 68 in response to the detection signal from the start winning port sensor 66. The winning lottery unit 68 performs a winning lottery using random numbers and determines either winning or losing. In the winning determination table used in the winning lottery, all the random numbers extracted in the lottery are assigned with one of the loses. In the winning lottery, the random number extracted at the time of the lottery wins, and the winning is determined depending on which of the values corresponds to the lost.

  The stop symbol determination unit 70 is operated after the winning lottery is executed, and determines a combination of symbols to be stopped and displayed based on the winning lottery result. The variation pattern lottery unit 72 is operated after the stop symbol is determined. The variation pattern lottery unit 72 performs a variation pattern lottery based on the winning lottery result, and determines a variation display mode (variation pattern) of the symbol performed on the liquid crystal display 20.

  In the pachinko machine 10, the same pattern is used for the pattern that is displayed in a variably displayed manner in each area of the liquid crystal display 20 in a predetermined order (for example, the order of the left area, the right area, and the middle area). After changing the display of the symbol (after reaching the reach state), the process until the symbol in the middle area is stopped is performed by changing the background image or making the character appear (changing the pattern) A plurality of types of variation patterns are prepared, and the main memory 64 stores pattern numbers corresponding to the variation patterns. In the variation pattern lottery, depending on which of the pattern numbers stored in the main memory 64 corresponds to the random number value extracted in the lottery, the variation display of the symbol is displayed with which variation pattern among the plurality of types of variation patterns. It is decided whether to do it.

  Further, the pachinko machine 10 includes a sub control board 80. The sub control board 80 is provided with a sub CPU 82 and a sub memory 84 in addition to the liquid crystal display 20 and the motor driver 48 described above. A command indicating the pattern number of the variation pattern determined by the variation pattern lottery is input from the main control board 60 to the sub CPU 82. The sub CPU 82 drives the liquid crystal display 20 on the basis of this command, and executes a variable display of symbols.

  The sub-memory 84 displays, from the liquid crystal display 20, symbol data used when symbol variation is displayed in each variation pattern, background image data of a symbol background image, character image data used for reach production, and the like. The display data of various images to be stored is stored. The sub CPU 82 reads out the display data from the sub memory 84 and performs variable display of symbols according to the variation pattern determined by the variation pattern lottery unit 72.

  The sub CPU 82 is connected to the first sensor 42, the second sensor 44, and the motor driver 48 described above, an effect drive execution unit (effect drive execution means) 90, an initial drive execution unit (initial drive execution means). ) 91, check signal output unit (check signal output unit) 92, correction drive execution unit (correction drive execution unit) 93, error signal output unit (error signal output unit) 94, drive stop unit (drive control unit) 95, error A return process execution unit (error return means) 96 is provided.

  When the variation pattern determined by the variation pattern lottery unit 72 is a predetermined variation pattern (for example, a variation pattern for performing a reach effect), the effect drive execution unit 90 performs the effect driving of the swinging accessory 24. The effect drive is to supply a drive pulse to the stepping motor 46 through the motor driver 48 so as to return to the initial position after moving along a preset route. The moving path of the swinging accessory 24 during the effect driving is set so that the effect driving ends before the symbol variation display with the predetermined variation pattern described above ends. In the present embodiment, when effect driving is executed, after 50 forward rotation pulses are output to the stepping motor 46, the process of outputting 50 reverse rotation pulses to the stepping motor 46 is repeated five times. That is, an example will be described in which when the effect driving is performed, the swinging accessory 24 swings five times and returns to the initial position.

  The initial drive execution unit 91 initially drives the swinging accessory 24 when the pachinko machine 10 is powered on. The initial drive is to supply a drive pulse to the stepping motor 46 so as to return to the initial position after sequentially moving to all movable positions. In the present embodiment, when the initial drive is executed, an example in which 50 forward rotation pulses are output to the stepping motor 46 and then 50 reverse rotation pulses are output to the stepping motor 46 is performed. When the initial driving is performed, an example will be described in which the swinging accessory 24 swings once and returns to the initial position.

  When the variation pattern determined by the variation pattern lottery unit 72 is the above-described predetermined pattern, that is, the pattern in which the effect driving is executed, the check signal output unit 92 performs the display of the variation display of the symbol. After completion), a check signal is output.

  When the check signal is output, the correction drive execution unit 93 determines whether or not the detection signal is output from the first sensor 42. If the detection signal is not output from the first sensor 42, that is, If the swinging combination 24 is not moved to the initial position despite the effect driving being completed, the swinging combination 24 is corrected and driven. The correction drive is to supply a drive pulse to the stepping motor 46 so as to return the swinging combination 24 to the initial position. In the present embodiment, when correction driving is executed, the reverse rotation pulse is applied to the stepping motor 46 one by one up to a predetermined number (for example, 10) until a detection signal is output from the first sensor 42. In the output example, that is, when the correction driving is performed, the swinging combination 24 is moved to the initial position until a predetermined number of reverse rotation pulses are output or until the swinging combination 24 is detected at the initial position. An explanation will be given by using an example of moving toward.

  The error signal output unit 94 monitors the position of the swinging accessory 24 based on detection signals from the first and second sensors 42 and 44. Then, the error signal output unit 94 generates an error signal when the swinging accessory 24 is not detected continuously several times at any one of the plurality of positions set as the movement destination during the effect driving. Is output. Specifically, when the swinging accessory 24 is not moved to the initial position when it should be moved to the initial position (detected from the first sensor 42 even though 50 reverse rotation pulses are supplied). When the signal is not output), the error signal output unit 94 determines that this is the first preliminary error, and stores the history of this preliminary error in the sub memory 84. Similarly, the error signal output unit 94 is configured such that when the swinging accessory 24 is not moved to the lower position when it should be moved to the lower position (the first counter pulse is supplied in spite of 50 forward rotation pulses being supplied). When the detection signal is not output from the two sensors 44), the error signal output unit 94 determines that this is the second preliminary error and stores the history of the preliminary error in the sub memory 84. The error signal output unit 94 outputs an error signal when the same preliminary error is detected twice consecutively.

  Further, the error signal output unit 94 outputs an error signal when the swinging accessory 24 is not detected at any of the plurality of positions set as the movement destination during the initial driving. Specifically, when the swinging accessory 24 is not moved to the initial position when it should be moved to the initial position (detected from the first sensor 42 even though 50 reverse rotation pulses are supplied). When no signal is output), and when the swinging accessory 24 is not moved to the lower position when it should be moved to the lower position (even though 50 forward rotation pulses are supplied) When the detection signal is not output from the second sensor 44), the error signal output unit 94 outputs an error signal.

  Further, the error signal output unit 94 outputs an error signal when the swinging combination 24 is not detected at the initial position after the correction driving. Specifically, the error signal output unit 94 outputs an error signal when a detection signal is not output from the first sensor 42 even though a predetermined number of reverse rotation pulses are output to the stepping motor 46.

  The drive stop unit 95 writes a drive prohibition flag in the sub memory 84 when an error signal is output. The sub CPU 82 stops the functions of the effect drive execution unit 90, the initial drive execution unit 91, and the correction drive execution unit 93 while the drive prohibition flag exists. As a result, while the drive prohibition flag exists, the driving force is not supplied from the stepping motor 46 to the swinging accessory 24.

  The error recovery process execution unit 96 is provided with a timer 97. When the error signal is output (when the drive prohibition flag is written in the sub-memory 84), the error recovery processing execution unit 96 starts time measurement by the timer 97, and a predetermined time (for example, 10 minutes) from the time measurement start. If a check signal is output after the elapse of time, error recovery processing is executed. The error recovery process is to erase the drive prohibition flag from the sub memory 84 and execute the initial drive described above.

  Hereinafter, the operation of the present invention having the above configuration will be described with reference to the flowchart shown in FIG. In the pachinko machine 10, when the power is turned on, the swinging accessory 24 is initially driven. If the swinging combination 24 is not detected at any of a plurality of positions set as the movement destination during the initial driving (when the initial driving is not performed normally), the swinging combination 24 Supply of driving force to is stopped.

  Further, in the pachinko machine 10, when the symbol variation pattern is a predetermined pattern, the swinging accessory 24 is driven. When the swinging combination 24 is not detected continuously at any one of the plurality of positions set as the destination during the effect driving (the same preliminary error is detected twice consecutively). In the case where the driving force is supplied to the swinging accessory 24 is stopped.

  Further, in the pachinko machine 10, when the symbol variation display is ended in the game in which the effect driving is executed (when the symbol variation display in the predetermined pattern is terminated and the check signal is output), the swinging accessory When 24 is not in the initial position, the swinging combination 24 is driven for correction. Then, when the swinging combination 24 is not detected at the initial position after the correction driving, the supply of driving force to the swinging combination 24 is stopped.

  As described above, when the supply of the driving force to the swinging accessory 24 is stopped, the time measurement by the timer 97 is started. When a check signal is output after a predetermined time has elapsed since the supply of the driving force to the swinging accessory 24 is stopped, an error recovery process is executed and the swinging accessory 24 is initially driven. .

  As described above, the pachinko machine 10 swings when a problem occurs such that the swinging accessory 24 cannot move to a predetermined position due to foreign matter such as dust caught between the gear 34 and the gear 40. The supply of driving force to the moving object 24 is stopped. For this reason, compared with the case where the driving force is continuously supplied so as to move the swinging combination 24 to a predetermined position in spite of the malfunction, the swinging combination 24, the gear 40, The load on the stepping motor 46 can be reduced, and these failures and damages can be prevented. Further, after the predetermined time has elapsed since the occurrence of the malfunction, when the symbol variation display is completed, the initial driving is automatically performed, so that the malfunction can be easily recovered.

  Further, during the effect driving, when the swinging combination 24 is not detected continuously at any one of a plurality of positions set as the movement destination a plurality of times, the drive to the swinging combination 24 is performed. Stop supplying power. For this reason, for example, when it is not detected that the swinging accessory 24 has moved to the initial position (or the lower position) only once due to a temporary malfunction of the first sensor 42 (or the second sensor 44). In spite of a temporary malfunction, the supply of the driving force to the swinging accessory 24 is not stopped.

  In addition, since this invention is not limited to the said embodiment, a detailed structure etc. can be changed suitably. For example, in the above-described embodiment, when the swinging combination is not detected continuously “at least twice” at any one of the plurality of positions set as the movement destination during the effect driving, Although the example of stopping the supply of the driving force to the accessory has been described, it is continuously shaken by “any predetermined number” or more at any one of a plurality of positions set as the movement destination during the production driving. When no moving object is detected, the supply of driving force to the swinging object may be stopped.

  Further, in the above-described embodiment, an example in which the swinging combination swings between the initial position and the lower position when the effect driving is performed has been described. However, when the effect driving is performed, the swinging function becomes the initial position. And an intermediate position (an intermediate position between the initial position and the lower position). In this case, in addition to the first and second sensors described above, a third sensor is provided for detecting that the swinging accessory has moved to the intermediate position, and during the effect driving, the swinging accessory is at the initial position or the intermediate position. When the swinging combination is not detected continuously for a predetermined number of times, the supply of the driving force to the swinging combination may be stopped.

  Of course, the present invention is not limited to the above, and the swinging mode of the swinging accessory can be freely set. For example, according to the variation pattern determined by the variation pattern lottery (for example, the type of reach production), the swinging combination is effect-driven so as to swing between the initial position and the intermediate position, and swinging You may switch between the cases where the effect is driven so that the accessory swings between the initial position and the lower position. Also in this case, if the swinging combination is not detected continuously for a predetermined number of times or more at any one of the plurality of positions set as the movement destination during each effect driving, What is necessary is just to stop supply of a driving force.

  Furthermore, in the above-described embodiment, the example in which the present invention is applied to the swinging accessory has been described. However, the present invention may be applied to other accessory (movable member). For example, when the present invention is applied to the rotating combination described in the above embodiment, the rotating combination 22 is correctly recognized at the initial position (for example, the upper and lower sides of the letters “Gold” described in the rotating combination 22 are correctly recognized). A sensor for detecting the position is provided. In addition, the rotating combination 22 is rotated clockwise from the initial position to the initial position during initial driving, is rotated three times from the initial position to the initial position during production driving, and is rotated clockwise during correction driving. A clockwise rotation pulse to be rotated is supplied until it moves to the initial position with a predetermined number as a limit.

  During the initial driving, when the rotating hand 22 is not in the initial position when it should be in the initial position (in spite of supplying a clockwise rotation pulse for rotating the rotating hand 22 by one rotation, the rotating hand 22 22 is not detected at the initial position), and during the effect driving, when the rotating accessory 22 is not detected continuously for a predetermined number of times or more at one of the set movement destinations (the rotating accessory 22 is rotated by one rotation). In the case where the rotating combination 22 is not detected at the initial position for a predetermined number of times in spite of supplying only the clockwise rotation pulse), and after the correction driving, the rotating combination 22 is not detected at the initial position. In this case, an error signal is output. When the error signal is output, the supply of the driving force to the rotating accessory 22 is stopped, and after a predetermined time has elapsed from the output of the error signal, the initial drive is executed when the check signal is output. That's fine.

  As described above, the present invention can also be applied to the rotating accessory 22, and by applying it, the same effect as in the above embodiment can be obtained. Note that the present invention may be applied to both the swinging combination 24 and the rotation combination 22. Of course, the present invention may be applied to a combination having a movement mode other than the swing combination 24 and the rotation combination 22.

  In the above embodiment, the driving force of the stepping motor is transmitted to the swinging accessory by the gear, that is, the driving force transmitting mechanism is a gear. However, the present invention is not limited to this. . Various known mechanisms can be used as the driving force transmission mechanism.

  Furthermore, in the above embodiment, the example in which the swinging member is swung using the stepping motor that rotates by the amount corresponding to the number of supplied drive pulses has been described. However, the rotation is performed only while power is supplied. The swinging accessory may be swung using a DC motor. For example, when the swinging combination used in the above embodiment is swung by a DC motor, power is supplied for a predetermined time when performing initial driving, effect driving, and correction driving (for example, in the initial driving, in the positive direction). After energizing for 1 second, it may be energized for 1 second in the reverse direction).

  If the error recovery process is executed during the symbol variation display and the accessory (movable member) is initially driven, the player may misunderstand that the expectation of winning is high. In order to prevent such a problem, it is preferable to execute the error recovery process within an interval time from the end of the symbol variation display to the start of the next symbol variation display. In this case, until the error recovery process is completed, the sub CPU suspends execution of the next symbol variation display, and can perform both effect driving and initial driving within the time required for symbol variation display. What is necessary is just to set the mode (time) of the change display of a symbol, and the movement mode (movement time) of the accessory in effect drive and initial drive.

  In addition, it is preferable to provide notifying means for notifying that the supply of the driving force to the accessory has been stopped by outputting an error signal and that the initial driving has been executed in accordance with the execution of the error recovery process. In this case, a plurality of LEDs may be provided as notification means, and the light emission mode of these LEDs (the position of the light emitting LED, the blinking interval, the lighting color, etc.) may be changed. Of course, a message or an error code may be displayed on the liquid crystal display, or notification from the speaker may be made. As described above, if the error signal is output and the supply of the driving force to the accessory is stopped and the fact that the initial drive is executed in accordance with the execution of the error recovery process, the player or the pachinko machine is notified. This is convenient because the operator of the amusement store where the machine is installed can know the reason why the accessory has stopped and the reason why the initial driving is executed even if it is not immediately after the power is turned on.

  Furthermore, in the above-described embodiment, the example in which the error history (the occurrence history of the first preliminary error and the second preliminary error) is stored in the sub-memory has been described. However, a dedicated memory for storing the error history may be provided. Good. In addition, for example, a movable body CPU that drives and controls the movable member may be provided separately from the sub CPU, and the error history described above may be stored in a memory in the movable body CPU.

  In the above-described embodiment, the example in which the check signal is output after the display of the variation of the symbol accompanied by the effect driving has been described, but the present invention is not limited to this. Since the check signal can be output at any timing as long as the movable member is not moving, for example, after the variation display ends, regardless of whether or not the variation display pattern involves effect driving. A check signal may be output. Also, a check signal may be output before the symbol variation display. Further, a built-in clock may be provided, and a check signal may be output every predetermined time, or a chuck signal may be output when the business hours of the pachinko store are over. Of course, an operation member may be provided and a check signal may be output in accordance with an operation from the operator.
