Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The pachinko gaming machine according to the present embodiment has an effect member that can be moved up and down at a predetermined position of the game board, and can produce an effect by raising and lowering the effect member according to the game content, as shown in FIG. Moreover, it has the front frame 3 to which the glass plate 2 was attached, and it is comprised so that a player can see the game board 4 through this glass plate 2. FIG.

  The game board 4 is formed with various accessories, a plurality of nails, a windmill, and the like, and a start opening 7 and a big prize opening 8 are formed. Further, an accessory 5 is fixed substantially at the center of the game board 4, and a symbol display means 6 including a liquid crystal display device is disposed inside the accessory 5. The symbol display means 6 can display a predetermined symbol or background on the screen.

  Then, when the starting condition is established by winning a game ball at the starting port 7, the symbols on the symbol display means 6 are displayed in a variable manner, and a plurality of symbols are stopped and displayed together to win a big win as a "big hit" state. A large number of game balls can be obtained by opening the mouth 8 at a predetermined time and timing. Further, a handle 11 is disposed at the lower right corner (position adjacent to the lower plate 10) of the pachinko gaming machine 1, and when the player rotates the handle 11 while holding the handle 11, the upper plate 9 is configured to launch game balls in the game board 4.

  Further, the pachinko gaming machine 1 is provided with an LED (not shown) that can be lit or blinked according to the game content, and a speaker (not shown) that can output sound, sound effects, etc. according to the game content. ) Etc. are arranged. Thereby, it is possible to sufficiently improve the effect on the player's vision and hearing and enhance the effect of production. In addition, you may comprise so that the handle 11 may vibrate etc. according to the game content, and a presentation effect may be further improved.

  The accessory 5 is fixed substantially at the center of the game board 4, and as shown in FIGS. 2 to 4, an opening 5a is formed in the center so that the screen of the symbol display means 6 can face the player. Has been. An effect member 12 that can be moved up and down is attached to the upper edge surface of the opening 5a. The effect member 12 can be moved up and down in accordance with the content of the game. Specifically, as shown in FIG. 10, the effect member 12 has a pair of protrusions 20 c formed in the inner space thereof toward the inside, and from the upper edge surface of the opening 5 a of the accessory 5. A spiral shaft 13 (rotational force applying means) that protrudes linearly downward is formed.

  The spiral shaft 13 is integrally formed with a fixing flange 14 at the upper end, and the fixing flange 14 is fixed to the upper edge surface of the accessory 5, and the projection 20 c of the effect member 12 is fitted on the side surface thereof. The groove 13a is formed in a spiral shape. The projection member 20c is engaged with the groove 13a, so that the effect member 12 is held at a predetermined position (that is, a position within the opening 5a of the accessory 5).

  On the other hand, as shown in FIG. 5, the effect member 12 includes a cylindrical member 20 formed in a cylindrical shape, a decorative receiver 21 that is inserted and attached through a lower end opening of the cylindrical member 20, and is inserted into the decorative receiver 21. The bearing collar 22 is fixed and the balance weight 23 is attached to the lower end of the cylindrical member 20 and has a predetermined weight. On the side surface of the cylindrical member 20, the blade portion extends so as to expand sideways. 20a and 20b are formed. Among these, the balance weight 23 functions as a weight of the effect member 12 as a whole. The pair of protrusions 20 c described above are formed so as to protrude inward from the inner wall surface on the upper end side in the internal space of the cylindrical member 20.

  However, the spiral shaft 13 is provided with a through hole 13b along the longitudinal direction inside, and a wire W (stainless steel wire) is inserted into the through hole 13b. A ball bearing 24 is fixed to the tip of the wire W, and the ball bearing 24 is attached to the decoration receiver 21 and the cylindrical member 20 via a bearing collar 22. Thus, the effect member 12 and the wire W are connected via the ball bearing 24, and the relative rotation (rotation about the rotation axis L) between the effect member 12 and the wire W is performed. It is allowed.

  As shown in FIG. 5, substrates 18 and 19 on which light-emitting diodes (LEDs) D1 and D2 are formed are disposed at both side positions facing the spiral shaft 13 on the upper end side of the accessory 5. . When the light emitting diodes (LEDs) D1 and D2 are turned on or blinked, the effect member 12 at the upper end (initial position) of the spiral shaft 13 can be illuminated.

  As shown in FIGS. 6 and 7, an idler pulley R1 is formed above the fixed position of the spiral shaft 13 in the accessory 5 (that is, above the effect member 12), and a stepping motor M ( A take-up pulley R2 that is coupled to the output shaft of the drive means) and can be driven to rotate is provided. In addition, the code | symbol B in the figure has shown the motor bracket. The wire W is wound around the winding pulley R2 via the idler pulley R1 in the initial state (the state where the effect member 12 is held at the upper end of the spiral shaft 13). That is, in the initial state, the effect member 12 is held at a predetermined position by the tension of the wire W.

  From this state, when the stepping motor M as the driving means is driven according to the game content and the winding pulley P2 is rotated in the direction in which the wire W is fed out, the effect member 12 falls downward (free fall) by its own weight. It will be. However, as described above, since the protrusion 20c is fitted in the groove 13a of the spiral shaft 13, the protrusion 20c slides along the groove 13a. Therefore, the effect member 12 rotates about the rotation axis L. However, it will fall by its own weight.

  Thereby, the spiral shaft 13 (rotational force applying means) can apply the rotational force to the effect member 12 by using its own weight when the effect member 12 is dropped by the spiral groove 13a. is there. In addition, since the relative rotation between the effect member 12 and the wire W is allowed by the ball bearing 24, it is avoided that the wire W rotates and twists with the effect member 12. Can do.

  Thus, after the production member 12 reaches the lower end of the spiral shaft 13, as shown in FIGS. When the wire W is dropped by the dimension of the drawn wire W, it reaches the lower end and is held again by the tension of the wire W, so that no further drop is made.

  Furthermore, the production member 12 is rotated for a while due to inertia even in the state of reaching the lower end, and it swings irregularly in the left-right direction in a state of being suspended by a wire. There is no production effect. That is, the effect member 12 is connected to the tip end of the wire W and freely falls to a predetermined position by its own weight, and then is pulled upward by the wire W to the initial position. The returning operation can be easily performed, and it swings left and right like a pendulum while being suspended by the wire W, and the swing becomes irregular.

  In addition, according to the effect member 12 according to the present embodiment, the effect member 12 freely falls downward from the upper edge surface of the opening 5a of the accessory 5, and thus operates (lifts and moves) on the front side of the symbol display means 6. It will be. As described above, since the symbol display means 6 can display the symbols in a variable manner or stop display according to the game content, the player's attention can be further improved, and the player can fall by his / her own weight. The effect produced by the member 12 can be further improved.

  In particular, in the present embodiment, the effect member 12 suspended by the wire W swings irregularly on the front side of the symbol display means 6, so that the player's attention can be further improved. In addition, since the wire W according to the present embodiment is made of stainless steel wire, it can be bent smoothly, and the effect member 12 suspended by the wire W can be irregularly and naturally shaken. A production effect that is not possible can be further achieved. Thus, the smoothly bendable stainless steel wire is taken up by the take-up pulley through the idler pulley without difficulty and naturally, so that the feeding and winding can be performed smoothly.

  As described above, after the effect member 12 freely falls while rotating, to return the effect member 12 to the original position (initial position), the winding pulley is wound in the direction in which the stepping motor M is driven to wind the wire W. Rotate P2. However, the effect member 12 is pulled upward by the wire W, reaches the lower end of the spiral shaft 13, and after the protrusion 20c is re-engaged with the groove 13a of the spiral shaft 13, the effect member 12 rotates in the direction opposite to that at the time of dropping. It rises along the groove 13a.

  Thus, after the effect member 12 is free-falling to a predetermined position by its own weight while being connected to the tip of the wire W, the effect member 12 is pulled upward by the wire W to the initial position. On the other hand, as shown in FIG. 5, a through hole 14a is formed in the fixed flange 14, and the sensor dog 15 held by the sensor mounting bracket 16 is inserted into the through hole 14a. The sensor dog 15 has an arm portion 15a that protrudes to the side. When the effect member 12 is below the initial position, the sensor dog 15 is in a state of being lowered downward by its own weight as shown in FIG. 15 a is in contact with the fixed flange 14.

  When the effect member 12 reaches the upper end (initial position), the sensor dog 15 is configured to be pushed upward by the effect member 12 as shown in FIG. In the vicinity of the sensor dog 15, a photosensor 17 capable of detecting the arm portion 15a when the sensor dog 15 is pushed upward is disposed. Thus, it is possible to detect whether or not the effect member 12 has reached the upper end by detecting the presence or absence of the arm portion 15a, and the stepping motor M can be stopped at that time.

  According to the above-described embodiment, the effect member 12 is freely dropped to a predetermined position by its own weight while being connected to the tip of the wire W, and then pulled upward by the wire W to the initial position. The returning operation up to the initial position can be easily performed, and the swinging motion can be performed irregularly in a state of being hung by the wire W, so that it is possible to produce an effect that is not found in existing ones. In addition, an idler pulley R1 located above the effect member 12 and a take-up pulley R2 connected to a stepping motor M (driving means) are provided, and the wire W is taken up via the idler pulley R1. Since it has been wound around the pulley R2 and can be fed and wound by forward or reverse driving of the stepping motor M (driving means), the stepping motor M (driving means) is placed above the effect member 12. The stepping motor M (driving means) can be laid out at an arbitrary position, and the degree of freedom in layout of the stepping motor M (driving means) can be improved.

  In addition, since the effect member 12 is rotated about the rotation axis L extending in the vertical direction and falls by its own weight (free fall), it is possible to produce an effect by a rotation operation in addition to the simple free fall as in the prior art. It is possible to further improve the effect of the effect member 12 falling due to its own weight. The effect member 12 is dropped at a predetermined timing according to the game content.

  Furthermore, since the spiral shaft 13 is provided as a rotational force applying means for applying a rotational force to the effect member 12 by utilizing its own weight when the effect member 12 is dropped, a separate drive source for rotation is provided. It can be made unnecessary and can be more reliably rotated when the effect member 12 falls freely according to the game content. In addition, since the effect member 12 has the blade portions 20a and 20b formed so as to expand laterally, it is possible to further improve the effect of the effect when falling (free fall) by its own weight while rotating.

  Furthermore, according to the present embodiment, the stepping motor M (driving means) capable of feeding and winding the wire W is provided, and the stepping motor M can be driven at a timing according to the game content. Thus, the dropping operation by the own weight of 12 and the returning operation to the initial position can be performed reliably and easily. Further, since the driving means capable of feeding and winding the wire W is composed of the stepping motor M, the dropping operation due to the weight of the effect member 12 and the returning operation to the initial position can be accurately performed at an accurate timing. .

Although the present embodiment has been described above, the present invention is not limited to this. For example, the effect member 12 is formed at a position different from the accessory 5 on the game board 4 and the rotation extending in the vertical direction at that position. It may be configured to fall by its own weight while rotating about an axis. In addition, as long as the effect member 12 is rotated about the rotation axis extending in the vertical direction and falls by its own weight, a separate drive source that applies a rotational force when dropped may be provided .

  Further, the rotation shaft of the effect member 12 is extended in another direction (a direction having a predetermined inclination angle with respect to the horizontal direction, the vertical direction, or the horizontal direction) instead of the one extending in the vertical direction as in the above embodiment. Also good. Furthermore, the appearance shape, form, etc. of the effect member 12 may be anything, and in addition to what is connected to the wire W, the effect member 12 falls by its own weight while rotating around the rotation axis extending in the vertical direction. Other configurations may also be used. Instead of the stepping motor M, another general-purpose drive source may be used.

The production member can be dropped by its own weight while rotating about the rotational force applying means, and when it is removed from the rotational force applying means, the rotation state is maintained by inertia and is connected to the tip of the wire to the predetermined position while being connected to the tip of the wire. After free-falling, the wire is pulled upward by the wire to be in the initial position, and includes an idler pulley positioned above the effect member, and a take-up pulley connected to the driving means. As long as the wire is a pachinko gaming machine that has been wound around the take-up pulley via the idler pulley and can be fed and taken up by driving of the driving means, the wire has a different appearance or other It can also be applied to those to which the above function is added.
