Next, the speed reduction mechanism (speed reduction means) 12 unique to the present application will be described.
As shown in FIGS. 2 and 3, the speed reduction mechanism 12 is formed in the vicinity of the uppermost portion of the substantially annular guide rail 11 in the vicinity of the game ball P in the moving direction, and in the vicinity of the upper end of the game area 5 a. A game ball decelerating passage 23 that is composed of (12) game nails 14a and a decoration rail upstream portion 11d that is an upstream portion in the movement direction of the game ball P in the decoration rail 11b and that can decelerate the ball speed of the game ball P. I have.

  The plurality of game nails 14a are continuously arranged in a continuous nail shape at a position spaced downward from the decorative rail upstream portion 11d by a predetermined distance, substantially parallel to the upstream portion 11d. Further, in order to reduce the impact of the game ball P on the central portion of the game nail 14a at the upstream end in the moving direction of the game ball P among the plurality of game nails 14a, the game nail 14a at the upstream end thereof is formed into a continuous nail shape. Five game nails 14b are arranged continuously toward the center of the game area 5a.

  At the end of the decorative rail upstream portion 11d, a convex ball stop member 25 depending on the end is integrally formed. The ball stop member 25 is formed with an opening 25a having a size through which the game ball P can pass, and a buffer member 25b is provided so as to face the opening 25a. The buffer member 25b receives and buffers the game ball P that is strongly launched toward the right side of the game area 5a, and bounces back the game ball P to guide it to the variable winning opening 17a. For example, rubber, soft It is formed of an elastic body such as a synthetic resin.

  As shown in FIG. 3, the game ball deceleration passage 23 is formed between the plurality of game nails 14 and the inner surface of the decorative rail upstream portion 11d on the upstream side in the movement direction of the game ball P from the buffer member 25b. In this game ball deceleration passage 23, an auxiliary member 24 made of a soft synthetic resin that continuously forms an uneven surface is provided on the surface of the decoration rail upstream portion 11d facing the game ball deceleration passage 23.

  The vertical width of the game ball deceleration passage 23 is, for example, relative to the diameter of 11 mm of the game ball P so that the game ball P contacts the plurality of game nails 14a and the auxiliary member 24 while passing through the game ball deceleration passage 23, for example. The upstream end is 15 mm and the downstream end is 12 mm, and is formed so as to gradually narrow from upstream to downstream. Therefore, the game ball P, which is strongly launched from the launch handle 10 and has a strong momentum, comes into contact with the plurality of game nails 14 and the auxiliary member 24 while passing through the game ball deceleration passage 23, so that the ball speed is decelerated. Even when the game ball P loses momentum while passing through the game ball deceleration passage 23, the game ball P falls due to its own weight.

Next, the effect of the speed reduction mechanism 12 of the first embodiment will be described.
In the pachinko machine 1 according to the first embodiment, the player operates the launch handle 10 so that the game machine P is continuously and powerfully fired, and the right hand strikes the game ball P on the right side of the game area 5a. Done. At this time, the game ball P is introduced into the upper portion of the game area 5a along the outer rail 11a, enters the game ball deceleration passage 23 on the upstream side in the movement direction of the game ball P from the buffer member 25b, and the game ball deceleration passage 23 The game ball P that is passing through comes into contact with the plurality of game nails 14 and the auxiliary member 24, and the speed of the ball is decelerated. After passing through the game ball deceleration passage 23, the game ball P is received and buffered by the buffer member 25b of the decoration rail 11b, and the game ball P rebounds from the buffer member 25b and moves in the direction of the variable winning opening 17a.

  As described above, the speed reduction mechanism 12 is connected to the decoration rail upstream portion 11d and the upstream portion 11d at a position spaced apart from the upstream portion 11d in a direction substantially parallel to the upstream portion 11d on the upstream side in the movement direction of the game ball P from the buffer member 25b. The game ball P is composed of a plurality of game nails 14a continuously arranged in a nail shape, and the game ball deceleration passage 23 is provided between them, so that the game ball P before the game ball P collides with the buffer member 25b. The ball speed can be surely decelerated. Thereby, even when the game ball P is strongly launched toward the right side of the game area 5a, it is possible to suppress variation in the moving direction of the game ball P that has collided and bounced off the buffer member 25b. P can be reliably moved in the direction of the third starting port 17a of the variable winning device 17.

  Further, since the vertical width of the game ball reducing passage 23 is formed so as to be gradually narrowed from the upstream to the downstream, the game ball P passing through the game ball deceleration passage 23 is formed with a plurality of game nails 14a and uneven surfaces. Can be reliably brought into contact with the auxiliary member 24, and the ball speed can be greatly reduced. In addition, it is difficult for the game ball P that has collided with the buffer member 25b to return to the game ball deceleration passage side.

  In order to alleviate the impact of the game nail 14a at the upstream end of the game ball P in the moving direction of the game balls P among the plurality of game nails 14a, the game area is continuously formed in a continuous nail shape from the game nail 14a at the upstream end. Since five game nails 14b are arranged toward the center of 5a, even if the game ball P repeatedly collides with the game nail 14a at the upstream end, the impact on the game nail 14a can be reduced. . Thereby, it is possible to prevent the gaming nail 14a at the upstream end from being bent or broken.

Next, a reduction mechanism 12A according to the second embodiment will be described. In addition, the same code | symbol is attached | subjected about the member similar to Example 1, and the detailed description is abbreviate | omitted.
As shown in FIG. 4, the speed reduction mechanism 12A includes a decorative rail upstream portion 11d and a soft synthetic resin game ball guide member 26 disposed substantially parallel to the upstream portion 11d, and the game ball P The game ball deceleration passage 23A that can decelerate the ball speed is provided.

  The game ball guide member 26 is a soft synthetic resin molded product formed in a rectangular shape in a front view, and is disposed substantially parallel to the upstream portion 11d at a position spaced downward from the decorative rail upstream portion 11d. ing. A pair of game nails 14c for preventing the game ball P from colliding with the upstream end and the downstream end in the movement direction of the game ball P in the game ball guide member 26 are provided at positions near both ends of the game ball guide member 26. It has been.

  The game ball deceleration passage 23A is formed between the inner surface of the decorative rail upstream portion 11d and the game ball guide member 26 on the upstream side in the movement direction of the game ball P from the buffer member 25b. In the game ball deceleration passage 23A, an auxiliary member 24 made of a soft synthetic resin that forms an uneven surface is formed on the surface of the decoration rail upstream portion 11d facing the game ball deceleration passage 23A. The vertical width of the game ball deceleration passage 23A is formed so as to gradually become narrower from upstream to downstream, and has the same width as the game ball deceleration passage 23 of the first embodiment.

Next, the operational effect of the speed reduction mechanism 12A according to the second embodiment will be described. The game ball P that is strongly launched from the launch handle 10 is introduced along the outer rail 11a into the upper portion of the game area 5a, and is played from the buffer member 25b. The ball enters the game ball deceleration passage 23 on the upstream side in the moving direction of P, and the game ball P passing through the game ball deceleration passage 23 comes into contact with the game ball guide member 26 and the auxiliary member 24, and the ball speed is decelerated. After passing through the game ball deceleration passage 23, the game ball P is received and buffered by the buffer member 25b of the decoration rail 11b, and the game ball P rebounds from the buffer member 25b and moves in the direction of the variable winning opening 17a.

Thus, the speed reduction mechanism 12A is substantially parallel to the upstream portion 11d at a position spaced apart from the decoration rail upstream portion 11d and the upstream portion 11d by a predetermined distance on the upstream side in the movement direction of the game ball P from the buffer member 25b. The game ball guide member 26 is disposed between the two and the game ball decelerating passage 23 is provided between them, so that the ball speed of the game ball P is surely increased until the game ball P collides with the buffer member 25b. It can be decelerated. Therefore, it is possible to suppress variation in the moving direction of the game ball P that has bounced off the shock-absorbing member 25b, and the game ball P can be reliably moved toward the third starting port 17a of the variable winning device 17.

  In addition, a pair of game nails 14c for preventing the game ball P from colliding with the upstream end and the downstream end in the movement direction of the game ball P in the game ball guide member 26 are provided at positions near both ends of the game ball guide member 26. Therefore, damage to the game ball guide member 26 can be prevented.

Here, a modified example in which the first and second embodiments are partially modified will be described.
1] As shown in FIG. 5, in the game ball deceleration passage 23B, the decoration rail 11b and the game ball guide member 26A may be integrally formed and fixed to the surface of the game board 5 with screws 28.

2] A backflow prevention valve may be provided on the downstream end side in the moving direction of the game ball P in the vicinity of both ends of the game ball guide member 26 of the second embodiment. The game ball P that has collided with the buffer member 25b is less likely to return to the game ball deceleration passage side.
3] The vertical width of the game ball deceleration passage of the first and second embodiments is not limited to the width described in the embodiment, and the game ball P is connected to the plurality of game nails 14a or the game ball guide member 26 in the game ball deceleration passages 23 and 23A. And any width that contacts the auxiliary member 24.
