Description

  The present invention relates to a ball biting prevention device for a gaming machine such as a pachinko machine.

Conventionally, the game board surface of a pachinko machine has been provided with a variable winning device such as a normal electric accessory or a special electric accessory, and when a predetermined opening condition is satisfied, the opening / closing piece is opened from the position where the winning opening is closed. When the predetermined closing condition is satisfied, the opening / closing piece is moved from the open position to the closed position.
When the open / close piece is opened and closed, the game ball is interposed between the open / close piece being moved and other parts such as the game nail, the edge of the winning hole, and the cover glass of the game board surface. It was happening that the condition was balanced. That is, there is a problem that the open / close piece is in a ball-engaged state in the middle of opening / closing.
As a conventional technique that may be able to prevent such a ball biting, Japanese Patent Application Laid-Open No. 2003-79861 discloses a technique in which a movable spring for opening and closing a movable prize-winning device is provided with a leaf spring that repels a pachinko ball. Yes.
JP 2003-79861 A

  However, in the conventional technique described in Japanese Patent Application Laid-Open No. 2003-79861, the pachinko ball is pushed in a direction perpendicular to the surface of the leaf spring. As a means for preventing the biting of the ball, it was not a sufficient means.

  Therefore, the present invention solves the above-described conventional problems, and a game ball that travels on a gaming board surface of a gaming machine such as a pachinko machine is interposed between a swinging piece such as an opening / closing piece of a prize opening and a component facing it. It is an object of the present invention to provide a ball biting prevention device for a gaming machine that can reliably prevent the ball biting that remains at the point.

In order to achieve the above object, a ball biting prevention device for a gaming machine according to the present invention includes a gaming ball between a swing piece on a game board surface on which the game ball travels and a component that faces the swing piece. A ball biting prevention device for a gaming machine that prevents the biting of a ball that stays in a state where the ball is interposed, and rotates to a portion that abuts on the intervening game ball in either or both of the swing piece and the opposing part The first feature is that a free rotation guide body is provided.
In the ball biting prevention device for a gaming machine according to the present invention, in addition to the first feature, the swing piece is an opening / closing piece for opening / closing a ball winning opening, and a rotation guide body is provided near the tip of the opening / closing piece. This is a second feature.
In addition to the first or second feature, the ball biting prevention device for a gaming machine according to the present invention has a third feature that the rotation guide body is a cylinder or a column that is rotatably supported.
Further, in the ball biting prevention device for a gaming machine according to the present invention, in addition to the first or second feature, the rotation guide body is a rotary belt rotatably supported by two parallel rotation shafts. 4 features.
In addition to the features described in any one of the first to fourth aspects, the ball biting prevention device for a gaming machine according to the present invention has a game nail as an opposing component, and a rotation guide body that rotates on the game nail. A fifth feature is that the cylinder is freely pivotally supported.

  In the first feature, when the game ball traveling on the game board surface enters between the swing piece and a component facing the swing piece and enters an intervening state, the swing piece with respect to the game ball is placed. And the rotation guide body provided on one or both of the parts and the rotation guide body, and the rotation guide body easily rotates by applying a slight force. At the contact point, the balance is easily lost in the tangential direction (a direction substantially perpendicular to the sandwiching direction). As a result, the game ball does not stay in the intervening state and quickly escapes from the state.

  In the second feature, the rotation guide body is provided in the vicinity of the tip of the opening / closing piece for opening / closing the winning opening, so that the game ball traveling on the surface of the game board faces the opening / closing piece of the winning opening and the opening / closing piece. Since the rotating guide body provided in the vicinity of the tip of the opening / closing piece comes into contact with the game ball when it enters between the parts to be inserted and enters an intervening state, the pinch balance with respect to the game ball is easily achieved by slight rotation of the rotation guide body Collapse. As a result, the game ball enters the winning opening or flows out of the winning opening. This also prevents the opening / closing piece of the winning opening from staying at the halfway opening / closing position.

  In the third feature, since the rotation guide body is a cylinder or a column, the game ball in the intervening state comes into contact with one point on the side circumferential surface of the cylinder or the column of the rotation guide body. For this reason, the positional instability in the interposed state of the game ball is large, and the balance is easily lost by a slight rotation of the rotation guide body. As a result, the game ball moves further without staying in the intervening state.

In the fourth feature, when a game ball traveling on the surface of the game board enters between an oscillating piece such as an opening / closing piece and a component facing it and enters an interposed state, the game ball serves as a rotation guide body. The rotating belt comes into contact. Since the rotating belt is supported by two rotatable rotating shafts that are rotatable, the rotating belt is rotatable. Therefore, when the game ball that has traveled contacts the rotating belt, the rotating belt rotates. As a result, the game ball easily loses its balance from the intervening state and exits the intervening state.
Further, when the rotating guide body is the rotating belt, the rotating belt is supported by two rotating shafts. Therefore, when a game ball hits the rotating belt, the collision force is somewhat absorbed. Become. Therefore, when the rotating belt is provided near the tip of the open / close piece of the winning opening, even if the game ball jumps into the open / closed piece in an open state, the momentum is absorbed by the rotating belt and relaxed. The For this reason, it is less likely that a game ball once entered the winning opening will jump out of the winning opening with that momentum.

  In the fifth feature, the rotation guide body is provided on the game nail opposed to the swinging piece such as the opening / closing piece, so that it does not have to be provided on the swinging piece such as the opening / closing piece. In addition, since the game nail is protected by a cylinder which is a rotation guide body, the occurrence of distortion such as deformation and warping is reduced in the game nail. Further, although depending on the material of the rotating guide body, the game ball colliding with the game nail is less likely to bounce.

According to the ball biting prevention device of the gaming machine according to claim 1, the game ball is interposed between the swing piece on the surface of the game board on which the game ball travels and a component that faces the swing piece. A ball biting prevention device for a gaming machine that prevents the biting of a ball that remains in a state where the ball is stuck, and is freely rotatable on a part of the swinging piece or any one or both of the parts that face each other and abutting against the intervening gaming ball Since there is a rotating guide body,
For example, even if the game ball is interposed between the swinging piece and the parts facing it, the rotation guide body can reliably prevent the game ball from remaining in the interposed state, and swinging The inconvenience that the piece stays at a halfway position can be reliably prevented.

According to the ball biting prevention device for a gaming machine according to claim 2, in addition to the effect of the configuration according to claim 1, the rotation guide body is provided in the vicinity of the tip of the opening / closing piece that opens and closes the winning opening. So
Even if the game ball may be interposed between the opening / closing piece of the winning opening and the parts facing it, the game ball is placed near the entrance of the winning opening by the rotating guide body provided near the tip of the opening / closing piece. It can be reliably prevented from staying in the intervening state, and can be led into the winning opening or led out of the winning opening. And it can prevent reliably that the opening-and-closing piece of a winning opening will be in the state which opened the winning opening halfway.

According to the ball biting prevention device for a gaming machine according to claim 3, in addition to the effect of the configuration according to claim 1 or 2, the rotation guide body is a cylinder or a column that is rotatably supported. So
The balance of the game ball in the intervening state can be easily broken, and the game ball can be more reliably prevented from remaining in the intervening state. Furthermore, even if the game ball is in an intervening state at any position in the length direction of the cylindrical or columnar rotation guide body, it can be reliably eliminated.

According to the ball biting prevention device for a gaming machine according to claim 4, in addition to the effect of the configuration according to claim 1 or 2, the rotation guide body is rotatably supported by two parallel rotation shafts. Because it is a rotating belt
The balance of the game ball in the intervening state can be easily broken by the rotating belt, and the game ball can be reliably prevented from remaining in the intervening state.
Further, when the rotating belt is provided near the tip of the opening / closing piece of the winning opening, even if the game ball jumps into the opening / closing piece in the open state, the momentum can be absorbed by the rotating belt. Therefore, it is possible to surely prevent an undesirable situation in which the game ball that has once entered the opening / closing piece jumps out of the winning opening with the momentum.

According to the ball biting prevention device for a gaming machine according to claim 5, in addition to the effect of the structure according to any one of claims 1 to 4, the parts that face each other are gaming nails, and the rotation guide Since the body is a cylinder rotatably supported by the game nail,
It is not always necessary to provide a rotating guide body on the swinging piece such as the opening / closing piece. However, if both are provided, the ball biting can be prevented more reliably.
In addition, a game nail that is frequently hit by a game ball can be protected by a cylinder that is a rotation guide body, whereby distortion and deterioration such as deformation and warping of the game nail can be reduced. Further, although depending on the material of the rotating guide body, it is possible to adjust the amount of the game ball that collides with the game nail to be small.
