Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a first state in which a ball is not received by standing up a ball receiving piece consisting of a first receiving piece and a second receiving piece that tilt in an articulated manner. The present invention relates to a winning device for a pachinko machine that can be converted into a second state in which the ball receiving piece is rotated sideways to receive a ball.

<Prior Art> As is well known, various winning devices have been proposed that change the receiving state of a batted ball by rotating ball receiving pieces pivoted on the left and right sides to stand up or fall sideways. This type of winning device has a winning chamber formed on the back side of a mounting board on which a ball receiving piece is pivoted, and a special winning hole and a general winning hole are arranged in parallel below the winning chamber, so that the ball hits the starting hole. When a certain condition is met, such as when the ball enters the ball, the left and right ball receivers are driven by a solenoid and the left and right ball receivers are rotated to change from the first state where they are upright to the second state where they are laid down on their side, and the ball that has flown down is placed on the ball receiver and placed in the winning chamber. It is intended to guide you.

In this type of winning device, if even one of the balls that entered the winning chamber enters the specified winning hole, the ball receiving piece is rotated again a predetermined number of times (for example, 18 times) as a bonus, and during this period, the ball is rotated a predetermined number of times (for example, 18 times). When it enters the specific winning hole again, the above 18 times are considered as one cycle, and it is set to be updateable up to a predetermined cycle (for example, 8 cycles).

<Problems to be Solved by the Invention> However, the above-described winning device simply rotates the ball receiving piece about the shaft as a fulcrum, so the movement of the ball receiving piece is simple and lacks interest. In addition, in order to increase the winning area of the ball, that is, to collect the balls flowing down the game board over a wide range, the ball receiver is made large, which requires a large driving force when rotating the ball receiver. As a result, the drive source and drive mechanism are likely to malfunction, the load on the fulcrum of the ball holder increases, and the ball holder is likely to be damaged.Furthermore, the winning device becomes large, so the general size of the game board The game range has become narrower, and the interest in playing pachinko has been lost.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and includes forming a winning chamber communicating with the opening on the back side of a mounting board having an opening, and a first receiving piece. A ball receiver piece that is tilted in an articulated manner and includes a second receiver piece is pivoted to the left and right sides of the mounting board, and the ball receiver piece is connected to a drive source via a communication mechanism, and is provided on the first receiver piece. By linking the joint shaft and the cam member provided in a part of the communication mechanism, the ball receiving piece can be brought upright and the first state does not receive a ball into the winning chamber, and the ball receiving piece can be moved by driving the drive source. It is configured to convert into a second state in which the ball is received into the winning chamber by rotating outward while tilting in a joint-like manner.

(Function) The first receiving piece and the second receiving piece are tilted in a joint shape with the joint axis as a fulcrum, and the ball receiving piece, which is in communication with the drive/source via the communication mechanism, is brought into an upright position by the drive of the driving source. The ball can be converted into a first state in which it does not accept a ball, and a second state in which it is tilted sideways and receives a ball.
