[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable prize device for a pachinko machine, and more particularly, to change a prize area of a pachinko ball (also referred to as a game ball) struck on a game board into a closed state and an open state. The present invention relates to a variable winning device that can be changed.

[0002]

2. Description of the Related Art As a typical example of such a variable prize apparatus implemented on a game board of each pachinko machine that plays various game contents, there is a variable prize apparatus of the following form as a typical example that has been often used in the past. . A so-called tulip-type accessory that is opened and closed using the game ball itself as a power medium. That is, the pair of left and right opening and closing members arranged on the front side of the main body are held in a normal narrow state where the winning area is narrowed at the upright facing position, and it is related to the passage of the game ball into this winning area. As a result, both opening and closing members are tilted outward to expand the winning area. Then, in connection with the passing of the game ball into the winning area, the two opening / closing members are returned to the original narrow closed state and held. What is called an electric accessory that is opened and closed by using an electric means (mainly a solenoid) as an opening and closing power medium. That is, the opening and closing member provided on the front surface of the main body (including wing-like and door-like)
The prize area is held in a normal closed state with the prize area closed, and when the opening condition generated during the game is satisfied, the opening / closing member is opened and changed to open the prize area as the electric means is operated for a set time. I do. The opening / closing member is returned to the original closed state when the electric means is stopped when any one of the limit conditions of the operation time (opening time) of the electric means or the winning number of the game balls in the winning area is reached. Is done.

[0003]

Although any of the above-mentioned variable winning devices can perform its function, there are the following problems. In the above-mentioned tulip-type accessory, since the mechanical opening / closing type using a game ball (safe ball) is used, the winning number of the game ball is always limited to a constant number (for example, one, two or other constant number). It is not possible to change the number of winnings and there is no applicability to change the usage. For this reason, when designing the game board (setting the game contents), one or two of the accessories must be strictly selected and adopted. Prize balls won for safe balls
If the payout ratio is different from the initially set allowable value, the game board may need to be redesigned again. Since the electric accessory is an electric opening / closing type using a solenoid or a switch, conditions for energizing the solenoid and detecting the number of switches can be easily selected and set. The winning number of game balls can be set to a required number within a set allowable value range. However, regardless of the structure and type, the solenoid, which is a power source, is continuously operated for a set time, and thus tends to be in a high temperature state. For this reason, when many opening conditions are satisfied during the game, aging or deterioration of functions due to the influence of overheating may appear, which may cause malfunction of the opening / closing member, and furthermore, the accessory itself However, there is a problem that the reliability of the device is impaired and the life is shortened.

[0004] Some of the above-mentioned electric auditoriums are abbreviated as "large-sized electric duties" and "small-sized electric duties" depending on the size of the winning area. Only the energizing operation time of the solenoid is restricted and use is permitted. However, even in such a case, there is a situation in which an operation failure due to aging or the like described above is likely to occur due to the establishment of many opening conditions.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the present invention has been proposed to solve the above-mentioned drawbacks, and uses a game ball (including a safe ball and a passing ball) for opening and closing control of an opening and closing member with respect to a winning area. The motor is used to change the opening and to return to the closed state at a predetermined time after confirming at least one safe ball entering the prize area. It is an object of the present invention to provide a variable prize winning device capable of improving operability and suppressing aging of an electric member so as to improve the reliability.

[0006]

[Means for solving the problems] To overcome the above-mentioned problems,
In order to achieve the intended purpose, the present invention comprises a main body which is attached to a required portion of a game board for pachinko balls, and has a winning area and a passage for game balls formed in the front and rear directions , The winning area
It is openably mounted to the front and rear directions with respect to the winning opening,

[0007]

[Action] Before the normal opening operation of the variable winning device,
Since the opening / closing member is held in the closed position by the first opening / closing restricting member, the game ball does not pass into the winning area. In this state, a game ball that has entered the ball passage from a predetermined portion of the game board is moved out of the ball passage after the interlocking member provided in the ball passage is changed. The first opening / closing regulating member is actuated by the interlocking change of the interlocking member to release the opening / closing member and open the winning area. On the other hand, at the time of the opening operation, since the opening / closing member is held at the open position, the game ball received by the member enters the winning area and is made a safe ball. In this state, after the safe means that has passed through the winning area is detected by the detecting means, the electric member is actuated at an appropriate timing, whereby the opening / closing member at the open position is closed via the second opening / closing regulating member.
