  Note that the reference numerals in the parentheses are for comparison with the drawings, but this is for convenience to facilitate understanding of the invention and has no influence on the description of the claims. It is not a thing.

  According to the first aspect of the present invention, the rendering device includes the light emitting portion, the covering portion, and the drive source, and the covering portion is supported so as to rotate in opposite directions in the left-right width direction of the light emitting portion. A predetermined number of first and second blade members, and the first group and the second group of blade members are driven by the driving force of the driving source at both ends, respectively. Since it is supported and supported so as to follow and follow the main driving operation, both ends of the first group and second group blade members are respectively supported in the main driving state and the driven state. It is possible to perform an effect of causing the light to leak from the gap between the blade members during the rotation by rotating it while shaking. For example, in the case of a bomb-type production device, it is possible to reproduce a state in which light is leaked from a plurality of muscles immediately before the explosion and the bomb bursts, and a powerful production with unexpectedness can be reproduced. Therefore, it is difficult to predict in what state light is emitted in the non-light emitting state by making a transition from the non-light emitting state to the light emitting state in an unexpected manner while performing the effect. Suddenly, it can be developed into an unexpected light emission state.

  According to the second aspect of the present invention, the first support portion supports one end portion of the first group of blade members in a free state with respect to the driving source on the upper side of the light emitting portion, and one end of the second group of blade members. The second support unit supports the other end of the first group of blade members below the light emitting unit so as to receive the driving force from the driving source. In addition, since the other end portion of the second group of blade members is supported in a free state with respect to the driving source, the entire covering portion can be individually rotated in the first group and the second group while efficiently pulling and shaking. The structure can be realized.

  According to the third aspect of the present invention, the drive units for rotating the first group and the second group of blade members by rotating the first drive shaft and the second drive shaft, respectively, are provided in the first and second groups. By rotating the specific blade member in each of the first and second drive shafts to individually rotate the first group and the second group of blade members, the entire covering portion is moved through the specific blade member. The first group and the second group are individually rotated, and the other blade members of the first group and the second group that follow the blade member via a specific blade member are rotated while effectively pulling and shaking. Can be moved.

  According to the fourth aspect of the present invention, the first support portion is positioned so as to protrude to the front side of the center accessory from the second support portion, and the first group and the second group of blade members are arranged before and after the center accessory. Therefore, the blade members of the first group and the second group, particularly the blade members located on the front side, are rotated in a direction to close with their own weights around the first and second drive shafts. Can be energized. Thereby, the blade member positioned on the front side in the closed state can be kept in contact with no gap, and the inside of the effect device can be maintained in a state invisible to the player in the non-light emitting state.

  According to the fifth aspect of the present invention, the drive unit is engaged with the first and second bevel gears fixed to the opposite ends of the first and second drive shafts, respectively, and the third bevel gear meshes with both the bevel gears. A drive motor fixed to the rotating shaft of the bevel gear, and the rotation of the first and second drive shafts receiving the rotation of the drive motor via the third bevel gear, the first bevel gear, and the second bevel gear. Since specific blade members in the first group and the second group are individually rotated, the first and second drive shafts are individually rotated by rotating the first and second bevel gears by one drive motor. Only a drive unit with a simple configuration can be realized, and thereby the entire rendering device can be made compact.

  According to the present invention of claim 6, the other end of the first group of specific blade members and the one end of the second group of specific blade members each have an engaging convex shape protruding in a predetermined direction. The blade members other than the specific blade member in the first group and the second group are configured to receive a pressing force from the other end portion and one end portion of the engagement convex shape around the first and second drive shafts. Therefore, when the specific blade member is rotated, the other blade member can be pressed in the same direction at the end of the engaging convex shape so that the other blade member can follow the specific blade member. It can be rotated while forming a slight gap between the pulling and shaking blade members. For example, in the case of a bomb-type production device, the moment when the bomb bursts can be realistically reproduced. .

The plate member 119 is flexibly inserted into the arc groove 119b. Since the one end portions 48a to 48c and the other end portions 58d to 58f are formed with cylindrical tips, the blade members 54a to 54f are moved when the tips slide and move in the arc grooves 106b and 119b. Even if it becomes slanted during operation, it is possible to prevent as much as possible the inconvenience that the cylindrical tip is detached from the arc grooves 106b and 119b. Further, collars 111, 98, 115, 117, 118 as bearings are fixed to specific portions of the first and second drive shafts 93, 97, and these collars are arranged around the drive shafts 93, 97. By being fitted between the cylindrical support walls 121, 122, etc., the clearance that causes play when the drive shafts 93, 97 are rotated is eliminated as much as possible. In addition, the code | symbol 112 in FIG. 8 has shown the housing part which connects the cylindrical support walls 121 and 122, and accommodates the 1st and 2nd bevel gears 104 and 105 rotatably.

  The drive unit includes first and second drive shafts 93 and 97, first and second bevel gears 104 and 105, a third bevel gear 113, and a drive motor 99. The first and second groups The first and second group of blade members 54a to 54c and 54d to 54f are provided by rotating the specific blade members 54c and 54f in the respective 54a to 54c and 54d to 54f from the first and second drive shafts 93 and 97. Are rotated individually. The first and second bevel gears 104 and 105 are fixed to opposite ends 93 c and 97 c of the first and second drive shafts 93 and 97, respectively, and the drive motor 99 meshes with both the bevel gears 104 and 105. The third bevel gear 113 is fixed to the rotating shaft 99a. The drive unit as described above is the first and second drive shafts 93 and 97 that receive the rotation of the drive motor 99 via the third bevel gear 113, the first bevel gear 104, and the second bevel gear 105. The specific blade members 54c and 54f in the first group and the second group are individually rotated. That is, by transmitting the rotation of the bevel gear 113 to the bevel gears 104 and 105 as reverse rotations, the first and second group of blade members 54a to 54c and 54d to 54f are rotated in the opposite directions.

  The other end portion 49c of the first group of specific blade members 54c and the one end portion 59f of the second group of specific blade members 54f are each formed into an engaging convex shape protruding in a predetermined direction. The blade members 54a, 54b, 54d, 54e other than the specific blade member in the first group and the second group are engaged with the end portions 49c of the engagement convex portions around the axes of the first and second drive shafts 93, 97. , 59f to receive a pressing force. That is, the blade members 54a, 54b, 54d, and 54e are engaged with the end portions 49c and 59f having the shape of engaging protrusions around the end portions 93b and 97b at the end portions 93b and 97b of the drive shafts 93 and 97. It has engaging convex parts 49a, 49b, 59d, 59e. When the specific blade members 54c and 54f are rotated, the end portions 49c and 59f press the engaging convex portions 49a, 49b, 59d and 59e of the blade members 54a, 54b, 54d and 54e in the same direction, thereby The members 54a, 54b, 54d, and 54e can be made to follow the blade members 54c and 54f.

  In addition, the code | symbols 93a and 97a in FIG. 8 are the ring grooves for fitting the C ring not shown formed in the edge parts 93b and 97b of the 1st and 2nd drive shafts 93 and 97, respectively.

Reference numeral 85 denotes a terminal.

  Next, the back structure of the pachinko machine 1 will be described with reference to FIG. FIG. 2 is a rear view showing the rear structure of the pachinko machine 1.

  That is, as shown in FIG. 16, a prize ball tank 43 is attached to the upper left side of the back of the front door of the pachinko machine 1, and the sub control board 38 and the main control board are located below the prize ball tank 43. 40 and the payout control board 51 are arranged in this order. An external terminal plate 52 is attached to the upper right side of the rear surface of the front door. Below the external terminal plate 52, an alignment standby passage 45, a prize ball device 46, a prize ball discharge passage 47, and a power supply unit 41 are provided. , And a launch control board 53 for a launcher (not shown) are arranged in this order. A locking device 13 is disposed on the left side of the back surface of the front door of the pachinko machine 1.

  Next, the control system of the pachinko machine 1 in the present embodiment will be described with reference to FIG. The figure is a block diagram showing a control system of the pachinko machine.

  That is, the present control system includes a game control device 80, a start chucker opening / closing solenoid 70, an attacker opening / closing solenoid 71, a sound emitting device 12, and a lighting device for effects 8, 11, which are electrically connected to the game control device 80. An image display device 35 and a rendering device 33 are provided.

  The game control device 80 includes the main control board 40 and the sub control board 38 shown in FIG. The main control board 40 manages the entire operation of the pachinko machine 1 in an integrated manner, and includes a system program for managing the entire operation of the pachinko machine 1 and a semiconductor memory in which a game execution program is stored in advance. And a storage unit (not shown) and a microprocessor (MPU) (not shown) that executes these programs. The sub-control board 38 is mainly configured to perform display control of image display, effects such as sound effects, and effect light.

  The game control device 80 includes a winning determination means 81, a winning signal output means 82, a first lottery means 83, a second lottery means 84, a normal symbol lottery means 94, a game control means 86, a holding means 87, an operation control means 88, and an operation. A determination unit 89, an operation determination unit 90, an effect control unit 91, and a display control unit 92 are provided.

  In the winning determination means 81, the game balls launched into the game area 3a by a launching device (not shown) that is operated by operating the launching handle 2 are the first and second start chuckers 27, 28, the general winning openings 25a, 25b, When winning a prize in any of 26a, 26b, attacker 5, etc., it is determined that there has been a prize.

  The winning signal output means 82, when the winning determination means 81 determines the winning, the winning indicating that the corresponding first and second start chuckers 27, 28, the general winning openings 25a, 25b, 25c, the attacker 5, etc. are won. Output a signal.

  The first lottery means 83 and the second lottery means 84 are less than the total maximum number of reserved balls when the winning signals corresponding to the first and second starting chuckers 27 and 28 are input from the winning signal output means 82, respectively. As a result of winning a prize, we will win either a probability change that will give a player a beneficial added value until the next jackpot is won, or a normal win that does not become the special state. Then, a winning random number is obtained from a lottery memory (not shown), and a big winning lottery (a lottery in a special gaming state) is executed.

  When the first and second lottery means 83 and 84 are each won by the jackpot lottery, the lottery is based on the random number value of the effect stored in the effect memory (not shown). A variation pattern indicating that corresponding symbols such as “111” are finally aligned on the jackpot effective line of the image display device 35 is determined, and a variation pattern signal indicating that is output. The “big hit effective line” means a position (line) where symbols should be arranged in a row in order to obtain a big hit.

  In addition, the first and second lottery means 83 and 84 each have a symbol such as “222” corresponding to the normal win as a result of the change in the lottery based on the production random number value when the normal win is won in the big win lottery. A variation pattern to be finally aligned on the jackpot effective line is determined, and a variation pattern signal to that effect is output. Furthermore, when the first and second lottery means 83 and 84 are out of the big hit lottery, the lottery based on the production random number value causes the symbol such as “252” corresponding to the outage to be on the big hit effective line. To determine a variation pattern to be finally aligned, and output a variation pattern signal to that effect.

  The normal symbol lottery means 94 performs a normal symbol lottery for opening and closing the second start chucker 28 with the passing of the game ball to the normal symbol operation gate 32 as an opportunity.

  The game control means 86 sends to the effect control means 91 an instruction that triggers the sound emitting device 12, the lighting devices 8 and 11, and the effecting device 33 to produce sound emission, light emission, and drive operation. Further, the game control means 86 relates to the contents of effects related to the jackpot lottery to be displayed on the image display device 35 in accordance with the preset effect data and the lottery results in the first and second lottery means 83 and 84. A signal is sent to the display control means 92.

  The holding means 87 receives the fluctuation pattern signal output from either the first or second lottery means 83 or 84, and executes the fluctuation pattern each time the first or second starting chuckers 27 and 28 are awarded. It is memorized sequentially as a reserved ball that will be the result of the lottery. The storage status is lit and displayed on a jackpot lottery hold display device (not shown) so that the sum of the start chuckers 27 and 28 is, for example, a maximum of 8 hold balls. The holding means 87 always determines whether or not the total number of balls to be held is eight, for example, and while the number of balls to be held is displayed eight times, the first and second starting chuckers 27 and 28 are informed. Despite winning a prize, no lottery will be drawn. Note that the number of reserved balls that are lit and displayed as reserved balls is not limited to the “maximum of eight”, and can be changed as appropriate according to the design.

  The holding means 87 sequentially outputs a signal related to the fluctuation pattern that is held (stored), and prevents the next fluctuation pattern signal from being output until the effect display based on the fluctuation pattern signal ends. A variation prohibition flag is set (turned on), and a symbol variation timer (not shown) for measuring the time for releasing the turned symbol variation prohibition flag is set, and the number of held balls according to the output of the variation pattern signal Is decremented by 1. Further, when the number of balls to be held becomes less than 8, for example, according to consumption of the balls to be held, the holding means 87 goes to the first and second starting chuckers 27 and 28 performed by the first and second lottery means 83 and 84. The result of the jackpot lottery in response to winning is stored as a holding ball, and the number of holding balls is incremented by one.

  The operation control means 88 sends a drive signal to the start chucker opening / closing solenoid 70 based on a signal indicating the start of operation of the operation determination means 90 to operate the solenoid 70, thereby opening or closing the second start chucker 28. . Further, the operation control means 88 sends a drive signal to the attacker opening / closing solenoid 71 to actuate the solenoid 71, and when the jackpot is generated by the lottery in the first and second lottery means 83, 84, the attacker 5 is opened and a predetermined number of prizes are won. Control is performed so that the closing operation is repeated a predetermined number of times (predetermined rounds) every time the operation ends (or a predetermined time elapses).

  The operation determination unit 89 determines whether or not a condition for operating the starter chuck opening / closing solenoid 70 and the attacker opening / closing solenoid 71 is satisfied. That is, in the start chucker opening / closing solenoid 70, when the “condition” of opening / closing of the second starter chucker 28 is satisfied, the normal symbol lottery means 94 is separate from the big hit lottery of the first and second lottery means 83 and 84. This is a case where a normal symbol lottery is won. In the attacker open / close solenoid 71, when the "conditions" for the opening of the attacker 5 are satisfied, three big symbols from the state of so-called reach (including so-called super reach and normal reach) are aligned on the big hit effective line and the big hit This is a case where it occurs, and the time when “the condition is satisfied” of the blockage of the attacker 5 is the case where winning in all rounds when the jackpot occurs is completed.

  In response to the determination signal from the operation determination unit 89, the operation determination unit 90 determines the start of operation of the starter chuck opening / closing solenoid 70 and the attacker opening / closing solenoid 71, respectively.

  In response to the command from the game control means 86, the effect control means 91 drives the sound emitting device 12 to emit sound, drives the effect lighting devices 8 and 11 to emit light, and causes the effect device 33 to emit light and / or operate. Drive to make the appeal to the player's hearing and vision.

  The display control unit 92 drives the image display device 35 in accordance with the signal from the game control unit 86, and displays the effect such as the contents centering on the big win lottery result so as to appeal to the player's vision. At that time, the display control unit 92 displays each lottery result by the first and second lottery units 83 and 84 on the screen 35a of the image display device 35 in time series.

  The start chucker opening / closing solenoid 70 opens and closes the second starter chucker 28 by moving a plunger (not shown) forward and backward in response to the drive signal transmitted from the operation control means 88. The attacker open / close solenoid 71 opens and closes the attacker 5 by moving a plunger (not shown) forward and backward in response to the drive signal transmitted from the operation control means 88.

  The sound emitting device 12 drives a speaker (not shown) according to the control of the effect control means 91, and emits a sound effect corresponding to the effect. The lighting devices for effect 8 and 11 drive the illumination lamp (not shown) built therein according to the control of the effect control means 91 (lighting and blinking), and perform illumination according to the effect. The image display device 35 operates according to the control of the display control means 92 and performs effect display according to the effect data and the lottery results in the first and second lottery means 83 and 84.

  The effect device 33 includes the LED 103 and the drive motor 99, and the LED 103 is driven to emit light and the drive motor 99 is driven to rotate according to the control of the effect control means 91 based on the command of the game control means 86. Open and close.

  Next, the operation of the pachinko machine 1 will be described with reference to the flowchart of FIG.

  That is, when a player who is seated facing the pachinko machine 1 holds the launch handle 2 and rotates it to an appropriate angle (step S1), the game ball 3 is played at predetermined time intervals by the operation of the launch device. Fired continuously towards Then, a large number of game balls which are launched into the game area 3a and roll and fall will win timely at the first and second starter chuckers 27 and 28 and the general winning holes 25a, 25b and 25c, or will not be involved in these. And is discharged to the back side of the game board 3 from an out port (not shown) at the bottom of the game area 3a.

  When a part of the game ball launched into the game area 3 a enters the warp introduction port 37, the game ball is discharged to the stage S from the game ball discharge port 34. At this time, the game ball released to the stage S passes through the recesses 61, 62, etc. from the rolling path, returns once on the inclined wall portion 63 side, and some of the gaming balls are released when the momentum of rolling is weakened. Some flow down from the concave portion 61 and the concave portion 62, and some fall from the ball discharge portion 24 toward the first starting chucker 27 below, and win the first starting chucker 27 with a high winning probability (approximately 100%).

  The game ball released from the ball discharge unit 24 wins the first starter chucker 27 with a high probability as described above, but may not win depending on the contact state with the obstacle nail 30. On the other hand, most of the game balls that are not introduced into the ball discharge unit 24 are released below the stage S and fall in a direction different from the first starter chucker 27, but in some cases, fall in a direction different from the first starter chucker 27. However, the obstacle nail 30 is repelled by a so-called jump nail (not shown) driven to the left or right of the obstacle nail 30 or a road nail (not shown) arranged in the left-right direction from the jump nail. In some cases, the first starter chucker 27 may win a prize by falling between them.

  By the way, when a game ball has won any of the first and second starter chuckers 27, 28 and the general winning openings 25a, 25b, 25c, the winning determination means 81 determines the winning and the winning signal output means. 82 outputs a winning signal (step S2).

  Then, when winning in the jackpot lottery (step S3), when the corresponding side of the first and second lottery means 83, 84 turns on the hit flag, the lottery is performed based on the rendering random number value stored in the rendering memory. , That is, a variation pattern corresponding to a probability variation or a normal variation is determined.

  In step S4, a winning symbol to be displayed on the image display device 35 is set, and the first lottery means 83 or the second lottery means 84 outputs a fluctuation pattern signal to that effect and produces an effect based on the fluctuation pattern signal. Until the display ends, the symbol variation prohibition flag is turned on to prevent transmission of the next variation pattern signal, and the symbol variation timer for measuring the time to release the turned on symbol variation prohibition flag is set, The number of reserved balls is decremented by 1 in response to the transmission of the fluctuation pattern signal. On the other hand, when the winning is a lottery lottery, a variation pattern is determined in which lottery based on a random number value stored in the effect memory results in the final matching of symbols corresponding to the loss as a result of the variation. Thereby, the off symbol displayed on the image display device 35 is set, and the first lottery means 83 or the second lottery means 84 outputs a variation pattern signal to that effect and turns on the symbol variation prohibition flag, A variation timer is set, and the number of reserved balls is decremented by 1 in response to transmission of the variation pattern signal.

  As described above, based on the fact that the game control means 86 transmits a signal related to the contents of effects to be displayed on the screen 35 a of the image display device 35 to the display control means 92, the display control means 92 is connected to the image display device 35. Is displayed in a timely manner so as to appeal to the player's vision of the contents related to the jackpot lottery result (step S5). At this time, if a command is issued from the game control means 86, the effect control means 91 emits the sound emitting device 12 in accordance with the effect on the screen 35a, and the effect lighting devices 8, 11 are driven to emit light. Alternatively, the production device 33 is driven to emit light and / or rotate, and the operation is controlled to increase the production.

  The rendering device 33 operates as follows during the rendering operation. In FIG. 1 and FIG. 2 and the like, the stage device 33 is depicted with the covering portion 54 open. However, in actual games, the covering portion 54 closes and the lens member 55 and the reflecting member 56 are closed. It is in a closed state that the player cannot see. In this closed state, the rendering device 33 is positioned such that the first support portion 74A protrudes to the front side of the center ornament 23 from the second support portion 74B, and the first and second group of blade members 54a to 54f. Is supported so as to incline forward in the front-rear direction of the center ornament 23. That is, since the upper side is arranged so as to protrude toward the near side of the center ornament 23 and the directing device 33 is positioned so as to fall slightly toward the near side, the entire blade member 54 of the first group and the second group, In particular, the blade members 54a and 54d located on the front side can be urged to rotate in the direction of closing with their own weights around the first and second drive shafts 93 and 97. Accordingly, the blade members 54a and 54d positioned on the front side in the closed state can be brought into contact with each other without a gap, and the inside of the effect device 33 can be maintained in a state invisible to the player in the non-light emitting state.

  On the screen 35a of the image display device 35, for example, two decorative symbols with the same numbers are arranged along one jackpot effective line (not shown) set so that three decorative symbols are arranged. When a reach occurs, a jackpot is generated when one more same decorative symbol is aligned on the jackpot active line (actually, a jackpot already determined by the lottery means 83 or 84 appears). In that case, the decorative pattern of the same number passes along with the decorative pattern of the other numbers through one position left on the jackpot active line, but the display control means 92 according to the selected effect pattern When the production develops (steps up) by the control, the flame is liquid crystal at the position where the decorative pattern passes through one position after being left on the jackpot effective line and overlaps with the light-emitting part 26a of the lead wire in the screen 35a. Is displayed.

  Then, the light emitting unit 26a emits light in time with the liquid crystal display, and it is produced as if the lead wire of the bomb-like lighting accessory 26 is lit. From this state, when the light emitting unit 36a and the light emitting unit 36b further emit light sequentially, the light emitting units 36a and 36b are sequentially ignited by the ignition of the light guide unit 26a. If the production ends at this point, one more decorative symbol will not be aligned on the jackpot effective line, and no jackpot will occur, but the production device 33 will start operating in the form of a spark from the light emitting part 36b, and the production will further develop Then, the reach that has already occurred becomes super reach, and a special character appears on the screen 35a.

  In that case, in the effect device 33, the LED 103 emits light under the control of the effect control means 91 based on the command of the game control means 86 from the state where all of the blade members 54a to 54f rotate forward and the inside cannot be seen, Under the control of the effect control means 91, the drive motor 99 is rotationally driven so as to vibrate little by little in the forward and reverse directions. Then, the light emission inside the rendering device 33 and the small vibrations of the blade members 54a, 54b, 54c, 54d, 54e, and 54f are combined, and the gap dimension between the blade members along each meridian L is slightly increased. Increasing or decreasing light leaks like a trembling light, and the situation is as if slow motion is expressed as if the bomb explodes. When the production is finished at this stage, one more decorative symbol will not be aligned on the jackpot effective line, and no jackpot will be generated, but from the light leakage state, the first group of blade members 54a to 54c and the second group When the blade members 54d to 54f are pivoted to the left and right and the lens member 55 is exposed, the so-called superheated super reach is developed, and the screen 35a provides a more gorgeous effect, which causes a big hit. Expectation is further enhanced.

  In this case, for example, as can be understood with reference to FIG. 9, when the drive motor 99 rotates counterclockwise, the rotation is transmitted to the first bevel gear 104 as rotation in the clockwise direction, and the second umbrella This is transmitted to the gear 105 as a counterclockwise rotation. Thus, on the first group of blade members 54a, 54b, 54c side, as can be understood with reference to FIGS. 8 and 12, the second drive shaft that rotates counterclockwise via the second bevel gear 105. The blade member 54c fixed to 97 rotates from the front position of the reflecting member 56 toward the rear. Then, the engagement protrusion-shaped end portion 49c of the blade member 54c presses and moves the other end portion 49b of the adjacent blade member 54b in the same direction, and the other end portion 49b of the blade member 54b is adjacent to the adjacent blade member 54b. The other end 49a of the blade member 54a to be pressed is moved in the same direction.

  As described above, the blade members 54b and 54a rotate in the same direction following the rotation operation of the blade member 54c that directly receives the rotational force from the second drive shaft 97. Since the one end portions 48b and 48a of 54a are inserted into the circular arc groove 106b of the disk member 106 with a margin and are supported flexibly, the other end portions 49b and 49a are interposed via the other end portion 49c of the blade member 54c. The blade members 54b and 54a that are rotated while being pressed rotate in a slightly vibrated state (pull-and-shake state) rather than smoothly.

  As a result, there is a slight gap between the blade members 54 a, 54 b, 54 c, 54 d, 54 e, and 54 f while making contact with each other, so that light is emitted in synchronization with the operation of the covering portion 54 and transmitted from the lens member 55. The projection light of the LED 103 that appears is in a state of being visible and hidden from the gap. Note that the second group of blade members 54d, 54e, and 54f proceeds in the same manner in the opposite relation to the above-described operation of the first group of blade members 54a, 54b, and 54c.

  Further, when the blade members 54a to 54f are operated, the shielding member 110 fixed to the first drive shaft 93 moves between the light projecting elements 107a and 108a and the light receiving elements 107b and 108b of the photo interrupters 107 and 108. A predetermined signal is generated, and the effect control means 91 feedback-controls the covering portion 54 while receiving the signal.

  Then, for example, when the remaining one decorative symbol is aligned on the jackpot active line and the lottery determination result appears on the screen 35a, the operation control means 88 is based on the signal indicating the operation start determination of the operation determination means 90. A drive signal is sent to the attacker open / close solenoid 71 at a predetermined timing, the solenoid 71 is operated to open the attacker 5, and a predetermined number of operations for closing every time a predetermined number of winnings are completed (or a predetermined time elapses). Repeat for (predetermined round). Thereby, a large amount of game balls corresponding to the game balls won in the attacker 5 are paid out from the ball supply port 17 to the dish unit 16 (step S6).

  As described above, in the present embodiment, the rendering device 33 applies a driving force to the light emitting portion including the lens member 55 and the LED 103, the covering portion 54 that is arranged to be openable and closable on the front side of the light emitting portion, and the covering portion 54. Three first group and second group blade members each having a driving motor 99 to be applied and supported so that the covering portion 54 rotates in opposite directions in the left-right width direction of the light emitting portion. 54a-54c, 54d-54f, and these blade members 54a-54c, 54d-54f are supported so that both ends receive the driving force of the driving motor 99 and perform a main driving operation. It is supported to follow and follow. For this reason, both ends of the blade members 54a to 54c and 54d to 54f are rotated while shaking the entire covering portion 54 supported in the main driving state and the driven state, respectively, and between the blade members during the rotation. An effect of leaking light from the gap can be executed. In this embodiment, since the production device 33 is a bomb type, it is possible to reproduce a state where the bomb bursts by leaking light from a plurality of muscles immediately before the explosion, and it is possible to reproduce a powerful production with unexpectedness. . Therefore, it is difficult to predict in what state light is emitted in the non-light emitting state by making a transition from the non-light emitting state to the light emitting state in an unexpected manner while performing the effect. Suddenly, it can be developed into an unexpected light emission state.

  In the present embodiment, the first support portion 74A supports the one end portions 48a to 48c of the first group of blade members 54a to 54c in a free state with respect to the drive motor 99 on the upper side of the light emitting portion, and the second portion.
