  However, in the conventional pachinko gaming machine described above, although the production member can achieve an unprecedented production effect by falling due to its own weight (so-called free fall), it is merely free fall, so the production effect It was insufficient to further improve. Under such circumstances, the present applicant has intensively studied in order to further improve the effect of the effect member that freely falls.

  This invention is made | formed in view of such a situation, and is providing the pachinko game machine which can further improve the production effect by the production member which falls by dead weight.

The invention described in claim 1 is a pachinko gaming machine that has an effect member that can be moved up and down at a predetermined position of the game board, and that can be operated by raising and lowering the effect member according to the content of the game. It can be dropped by the wire, and it is connected to the tip of the wire and freely falls to a predetermined position by its own weight by feeding the wire, and then pulled upward by winding the wire to be an initial position. formed to protrude downward Rutotomoni, by utilizing its own weight at the time of fall of the director member comprises a shaft to impart rotational force to the effect members, the process of the effect member falls along said shaft in the rotation force is applied, after free fall off the said shaft while the rotation is maintained, it is configured to be returned to the initial position And, when the effect member returns to the initial position after the free fall, from the first winding process of the effect member reaches the shafts bets, towards the second winding process of the presentation member returns to the initial position along said shaft However, the wire winding speed is set to be slow.

  According to a second aspect of the present invention, in the pachinko gaming machine according to the first aspect of the present invention, the pachinko machine includes a driving means capable of feeding and winding the wire, and the driving means includes a stepping motor.

  According to a third aspect of the present invention, in the pachinko gaming machine according to the first or second aspect, a bearing is formed at the tip of the wire, and the wire and the effect member are connected via the bearing. Features.

  According to the first aspect of the present invention, the effect member can be dropped (free fall) by its own weight while rotating, so that the effect by the rotation operation can be performed in addition to the conventional free fall. The production effect by the production member falling due to its own weight can be further improved. In addition, the directing member freely drops to a predetermined position with its own weight while being connected to the tip of the wire, and then pulled upward with the wire to the initial position, so the dropping operation by its own weight and the returning operation to the initial position are performed. Since it can be easily performed and swings irregularly in a state of being hung by a wire, it is possible to achieve a production effect that is not found in existing ones.

In addition, it formed to project downward Rutotomoni, since by utilizing its own weight at the time of fall of directing member comprising a shaft to impart rotational force to the effect members, separate driving source or the like for rotation When the effect member falls freely according to the content of the game, the effect member can be rotated more reliably, and the effect member can be dropped with a simple configuration without requiring a separate drive source. The rotational force can be applied to the effect member using its own weight.

In addition, when the effect member returns to the initial position after the free fall, from the first winding process of the effect member reaches shafts bets found the following second winding process of directing member returns to the initial position along the shaft Since the winding speed of the wire is set to be slow, the effect member can be quickly raised in the first winding process, and the effect member is surely matched with the shaft in the second winding process. It can raise along a shaft, and the return operation | movement to the initial position of the said production | presentation member can be performed more reliably and smoothly.

  According to the second aspect of the present invention, the driving means capable of feeding and winding the wire is provided, and the driving means is composed of a stepping motor, so that the dropping operation due to the weight of the effect member and the returning operation to the initial position can be accurately performed. It is possible to perform it accurately at a proper timing. In addition, since the driving means is a stepping motor, the winding of the wire is more in the second winding process in which the effect member returns to the initial position along the shaft than in the first winding process in which the effect member reaches the tip of the shaft. It is possible to easily perform setting and control such that the taking speed becomes slow.

  According to the invention of claim 3, since the bearing is formed at the tip of the wire, and the wire and the effect member are connected via the bearing, relative rotation between the effect member and the wire is allowed. Even if the effect member rotates in the reverse direction of the dropping in the process of rising after the free fall, it can be returned to the initial position while reliably avoiding the twisting of the wire.

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 (cylindrical member) 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 the decorative member A bearing collar 22 inserted and fixed inside the receiver 21 and a balance weight 23 attached to the lower end of the cylindrical member 20 and having a predetermined weight are formed on the side surface of the cylindrical member 20 toward the side. Blade portions 20a and 20b are formed so as to expand. Among these, the balance weight 23 functions as a weight of the effect member 12 as a whole.

  The pair of protrusions 20c described above are formed so as to protrude inward from the inner wall surface on the upper end side in the internal space (insertion space 20d) of the cylindrical member 20 as a cylindrical member, and the insertion space 20d is formed of a wire. While the wire W is inserted, the wire W is allowed to slack (see the two-dot chain line in FIG. 11). That is, the slack of the wire W that occurs when the effect member 12 freely falls is allowed in the insertion space 20 d in the cylindrical member 20. In the present embodiment, the inside of the cylindrical cylindrical member 20 is the insertion space 20d, but any other cylindrical shape can be used as long as the wire W can be allowed to loosen while being inserted. Good.

  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 (cylindrical member 20) and the wire W are connected via the ball bearing 24, and the relative rotation (centering on the rotation axis L) between the effect member 12 and the wire W is performed. Rotation) 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 R <b> 1 is formed above the fixed position of the spiral shaft 13 in the accessory 5, and is connected to the output shaft of the stepping motor M in the vicinity thereof so as to be driven to rotate. A take-up pulley R2 is also 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 is driven in accordance with the game content and the take-up pulley P2 is rotated in the direction in which the wire W is fed, the effect member 12 falls downward (free fall) by its own weight. 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. Here, at least after the effect member 12 reaches the lower end of the spiral shaft 13, the driving speed of the stepping motor M is set so that the feeding speed of the wire W becomes faster than the free fall speed of the effect member 12, The production member 12 is dropped by its own weight (free fall excluding restraint by the wire W). Thus, the wire W inevitably loosens when the effect member 12 falls freely.

  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 near side of the symbol display means 6, so that the degree of attention of the player can be further improved. Since the slack of the wire W is allowed in the insertion space 20d of the cylindrical member 20, the slack of the wire W when the effect member 12 falls freely interferes with surrounding components formed in the accessory 5 Can be avoided. In addition, since the wire W according to the present embodiment is made of a 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.

  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.

  Here, in this embodiment, when the effect member 12 returns to the initial position after the free fall, the effect member 12 reaches the tip (lower end) of the spiral shaft 13 (from the drop point of the effect member 12 to the spiral shaft 13). Ascending process up to the tip: Hereinafter, this is referred to as a “first winding process”, and a process in which the projection 12c of the effect member 12 is returned to the initial position while being engaged with the groove 13a of the spiral shaft 13 (projection 12c). Is a stepping motor in which the winding speed of the wire W is slower in the process of returning to the initial position after the groove 13a is matched and re-fitting (hereinafter referred to as "second winding process"). A driving speed of M is set.

  For example, as shown in FIG. 12, the winding speed α of the wire W in the first winding process from the dropping point a to the position b where the effect member 12 after free fall reaches the tip (lower end) of the spiral shaft 13. The winding speed β of the wire W (driving speed of the stepping motor M) in the second winding process from the position b to the initial position c is set to be slower than (driving speed of the stepping motor M). -ing

  As a result, the effect member 12 can be quickly raised in the first winding process, and the protrusion 12c of the effect member 12 is reliably aligned with the groove 13a of the spiral shaft 13 and slid in the second winding process. It is possible to perform the return operation to the initial position of the production member 12 more reliably and smoothly. In the first winding process and the second winding process, the winding speed of the wire W is preferably set so that an excessive load is not applied to the wire W.

  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 embodiment, the effect member 12 is connected to the tip 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. In addition, the return operation to the initial position can be easily performed, and the swinging motion is irregularly performed in the state of being hung by the wire W, so that it is possible to achieve a presentation effect that is not found in existing ones.

  Thus, the effect member 12 includes the cylindrical member 20 as a cylindrical member in which the insertion space 20d that allows the wire W to pass therethrough and allows the slackness of the wire W to be inserted, so that the effect member 12 falls freely. It is possible to avoid the wire W from interfering with surrounding components due to the slack of the wire W occurring at the time, and the effect member 12 can be more smoothly dropped. Further, since the slack of the wire W is allowed in the insertion space 20d of the cylindrical member 20, the slack is not hidden from the player side and can be improved when the effect member 12 is dropped. .

  Since the production member 12 rotates about the rotation axis L extending in the vertical direction and falls by its own weight (free fall), in addition to the one that simply falls freely as in the past, the production by the rotation operation can be performed. The effect of the effect member 12 falling due to its own weight can be further improved. The effect member 12 is dropped at a predetermined timing according to the game content.

  However, according to the present embodiment, the ball bearing 24 is formed at the tip of the wire W, and the wire W and the cylindrical member 20 are connected via the ball bearing 24 (strictly speaking, the bearing collar 22 and the decoration receiver 21 are connected. And the relative rotation (rotation around the rotation axis) between the effect member 12 and the wire W is allowed, and the wire W rotates and twists with the effect member 12. Can be avoided. Therefore, the raising and lowering operation of the effect member 12 can be performed more reliably and smoothly by interposing the ball bearing 24. In particular, in the present embodiment, even if the effect member 12 is rotated in the reverse direction of the fall in the process of rising after the free fall, the wire W can be returned to the initial position while reliably avoiding the twist.

  In addition, 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. Furthermore, 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. . Further, since the driving means is composed of the stepping motor M, the projection 12c of the effect member 12 is initially engaged with the groove 13a of the spiral shaft 13 from the first winding process in which the effect member 12 reaches the tip of the spiral shaft 13. In the second winding process of returning to the position, setting and control such that the winding speed of the wire W is reduced can be easily performed.

  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. Furthermore, in this embodiment, a rotational force is applied by descending the groove 13a of the spiral shaft 13 while the projection 20c of the effect member 12 is fitted, but a spiral groove is formed on the effect member 12 side. Further, a protrusion may be formed on the shaft side, and the protrusion may be lowered while fitting the protrusion into the groove to apply a rotational force. Instead of the stepping motor M, another general-purpose drive source may be used.

When the effect member returns to the initial position after the free fall, from the first winding process of the effect member reaches shafts bets found the following second winding process of directing member returns to the initial position along the shaft, the wire turns of If it is a pachinko gaming machine set so as to slow down the take-off speed, it can be applied to a machine having a different external shape or another function added.
