DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having a structure for changing the behavior of a pachinko ball.

[0002]

There is a pachinko machine in which a pachinko ball hit into a game board is caused to collide with an upper windmill and then collide with a lower obstacle nail. In the case of this configuration, when the pachinko ball hits the windmill, the direction and speed of the fall of the pachinko ball change, so that the collision direction and speed of the pachinko ball against the obstacle nail vary, giving a change to the behavior of the pachinko ball. Can be

In the above configuration, the speed and angle at which the pachinko ball hits the windmill are not constant, and the direction and speed of the bouncing of the pachinko ball become random. Therefore, it is possible to arbitrarily control the behavior change of the pachinko ball. Can not. Therefore, as described in JP-A-6-154393,
It is considered that the pachinko balls are stocked in the ball passage and then dropped freely as a whole. However, in this configuration, the falling direction of the pachinko ball can be arbitrarily set, but the falling speed of the pachinko ball cannot be controlled.

[0004] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pachinko machine that can set the falling direction of a pachinko ball arbitrarily and control the falling speed of the pachinko ball. .

[0005]

According to a first aspect of the present invention, there is provided a pachinko machine, wherein a ball path is provided on a game board and into which a pachinko ball struck into the game board enters and a ball provided on at least one side of the ball path. It is characterized in that it comprises a resistance member for imparting contact resistance to the pachinko ball in the passage, and a drive source for adjusting the release speed of the pachinko ball released from the ball passage by driving the resistance member. . According to the above-described means, when the pachinko ball hit into the game board enters the ball passage, the pachinko ball advances along the ball passage while contacting the resistance member, and then moves at a speed corresponding to the driving speed of the resistance member. Is released from the ball passage. For this reason, the falling direction of the pachinko ball is arbitrarily set and the falling speed of the pachinko ball is also controlled, so that the behavior of the pachinko ball is changed.

The pachinko machine according to the second aspect is characterized in that the resistance members are provided on both sides of the ball passage, and the resistance members on both sides are driven at different speeds. According to the above means,
A rotational force is applied to the pachinko ball released from the ball passage. For this reason, a large change occurs in the direction in which the pachinko ball hits the obstacle nail, the windmill, and the like, so that the behavior of the pachinko ball is further changed.

A pachinko machine according to a third aspect is characterized in that the resistance member is constituted by a belt. According to the above means, the followability of the pachinko ball to the belt is improved. For this reason, the pachinko ball is reliably released from the ball passage at a speed corresponding to the driving speed of the belt, so that the falling speed of the pachinko ball can be easily controlled. In addition, the number of pachinko balls in the ball passage can be easily adjusted only by changing the length of the belt, and the direction in which the pachinko balls are released from the ball passage can be easily adjusted only by changing the tensioning direction of the belt. Therefore, the degree of freedom in design is improved.

A pachinko machine according to a fourth aspect is characterized in that the resistance member is constituted by a roller. According to the above-described means, unlike the case where the resistance member is formed of the belt, the trouble of correcting the slack of the belt is not required, so that the maintainability is improved.

The pachinko machine according to the fifth aspect is characterized in that a plurality of resistance members comprising rollers are arranged along both sides of the ball passage. According to the above-mentioned means, a plurality of pachinko balls simultaneously enter the ball passage, and each pachinko ball is released from the ball passage while rolling like a dance, thereby producing a visual effect.
