<Operation details of the gaming machine>
In the pachinko machine 1 configured as described above, when a game ball is launched from a launching device (not shown) by the turning operation of the launch handle 7, and the launched game ball wins the start winning opening 15, A jackpot lottery (selection of random numbers) is executed in the control device installed inside, and if the jackpot lottery results in a “jackpot”, a “jackpot state” occurs. In addition, every time a game ball wins the start winning opening 15, the lottery of the symbol variation mode is executed simultaneously with the jackpot lottery, and one variation is selected from the plurality of variation modes stored in the storage means of the control device. A mode is selected, and based on the variation mode, the symbol display device 19 displays the variation of the symbol for a predetermined time. Then, the result of the jackpot lottery is displayed by displaying the “big hit symbol” or the “outlier symbol” after the variation display.

  In the “hit state”, the door member of the big prize opening unit 18 is opened intermittently a predetermined number of times. Therefore, when a “hit” occurs, the player can win a lot of prize balls by winning a lot of game balls in the big prize opening unit 18.

<Operation contents of mechanical production device>
In the pachinko machine 1, as described above, every time a game ball wins the start winning opening 15, a lottery of a symbol variation mode is executed, but a predetermined variation mode (for example, a so-called reach variation mode) is selected. In such a case, the mechanical performance device 31 performs a performance operation at a predetermined timing. When the mechanical performance device 31 is operated, power is supplied to the motor 37 that is a drive device. When power is supplied to the motor 37, the shaft of the motor 37 rotates from a predetermined position (counterclockwise), and the drive gear 38 rotates in the same direction.

  When the drive gear 38 rotates as described above, the interlocking gear 39 and the crank gear 40 rotate, and the drive arm 34 connected to the crank gear 40 via the connecting arm 36 rotates about the pivot boss 69 ( Counterclockwise). When the drive arm 34 rotates as described above, the movable member 32 pivotally attached to the drive arm 34 moves upward along with the rotation (moves upward while drawing an arc). When the movable member 32 ascends as described above, the driven arm 35 is pivotally attached to the movable member 32 in a state of intersecting the drive arm 34, so that the movable member 32 rotates (counterclockwise). It moves upward (see FIG. 5A).

  When the drive arm 34 is rotated by a predetermined angle, the lower side of the connecting portion 67 of the drive arm 34 comes into contact with the fixed protrusion 56 of the base plate 49 of the support member 33, and the rotation of the drive arm 34 is restricted. Is done. As described above, when the drive arm 34 rotates until the lower side of the connecting portion 67 contacts the fixed protrusion 56, the stopper 78 of the driven arm 35 enters the fitting recess 72 of the drive arm 34. (See FIG. 5B).

  Since the mechanical performance device 31 operates as described above, the movable member 32 is normally hidden behind the shielding plate 12 of the large game member 11 at the predetermined timing as shown in FIG. The movable member 32 suddenly protrudes inside the shielding plate 13 while rotating. Further, as described above, when the movable member 32 rises while rotating while drawing an arc, power is supplied to a substrate (not shown) located on the back side of the movable member 32 and mounted on the substrate. The emitted LED emits light, and the word “ground” emerges from the surface layer.

  Further, after the movable member 32 protrudes to the left for a predetermined time, the movable member 32 is retracted into the shielding plate 12. When the movable member 32 is retracted, power is supplied to the motor 37 and the shaft of the motor 37 rotates in the reverse direction (clockwise), and the drive arm 34 is rotated with the rotation of the interlocking gear 39 and the crank gear 40. Rotates around the pivot boss 69 (clockwise). As the drive arm 34 rotates, the movable member 32 moves downward (clockwise) while moving (moves downward while drawing an arc). When the driven arm 35 is rotated by a predetermined angle as the movable member 32 is lowered (clockwise), the detection blade 79 of the driven arm 35 enters between the detection plates 84 and 84 of the sensor 45, and the motor 37. The power supply to is cut off, and the lowering of the movable member 32 stops.

<Effects of gaming machines>

Since the content is novel and a very high performance effect can be exhibited, the game is highly attractive and the player's willingness to play can be kept high for a long period of time.

  In addition, the pachinko machine 1 is pivotally attached to the movable member 32 at one end and is capable of rotating in a plane parallel to the plate surface of the game board 4 and a state intersecting with the drive arm 34. The motor is a driving device for rotating the driven arm 34 and a driven arm 35 that is pivotally attached to the movable member 32 at one end and is rotatable in a plane parallel to the plate surface of the game board 4. 37 constitutes the mechanical performance device 31, and the movement of the movable member 32 that moves up and down while rotating in a plane parallel to the plate surface of the game board 4 is dynamic and smooth. In addition, since the structure of the mechanical performance device 31 is simple, it can be configured at low cost, and maintenance is easy.

  Further, the pachinko machine 1 is provided with a sensor 45 that is a driving stop means for detecting that the driven arm 35 has rotated to a predetermined position and stopping the driving by the motor 37 on the mechanical rendering device 31.
