DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize winning device of a pachinko machine provided with a variable prize ball device for increasing the probability of winning based on a prize of a specific winning opening (starting opening).

[0002]

2. Description of the Related Art A pachinko machine is provided with many mechanical devices such as a prize ball payout device, and the components constituting these mechanical devices need to be precisely adjusted. The ball is constantly receiving vibrations caused by the operation of the pachinko ball (hereinafter, referred to as “launching ball”) and the mechanism itself.

[0003] One of these mechanism devices is called a variable winning ball device. This variable winning prize ball device is provided with a space portion, and has a main structure that has a main frame disposed on a player side surface of a game board. An opening / closing member is provided. The opening / closing member operates when the launching ball wins a starting port which is a specific winning port provided on the game board, and opens and closes the notch. And
When the opening / closing member is operated, the shooting sphere flows into the space from the notch and is taken into the variable winning sphere device, and the taken shooting sphere is subjected to a winning process. For this reason, when the opening / closing member is operated, the launch ball can flow into the variable winning ball device, and the winning probability increases.

A small winning opening for performing a normal winning process and a large winning opening for performing a normal winning process for performing a normal winning process and continuously operating the opening / closing member for a predetermined time are provided inside the variable winning ball device. Is provided. Then, when the launch ball taken into the variable winning ball device by opening and closing the notch according to the winning in the starting opening wins the big winning opening, the big winning process is performed. When the launch ball taken into the variable winning prize device during the special prize processing wins the special prize opening, the special prize processing, that is, the continuous operation of the opening / closing member is newly started, and the right (winning) advantageous to the player is achieved. (Probability expansion) is extended.

[0005] In this embodiment, the variable prize ball device has a cutout perforated in the main frame. However, depending on the model, a cutout or an opening is formed in a decorative plate forming the same plane as the game board. Some have been set up. In this case, when the opening / closing member that opens and closes the notch (opening) is opened, the opening / closing member serves as a guide for causing the pachinko ball to flow into the notch, and the flowing pachinko ball is collected and the inflow ball wins. Processing is performed. Further, the large winning opening and the small winning opening are arranged in the notch.

The opening / closing member is controlled by an opening / closing solenoid comprising a straight-moving solenoid. The opening / closing solenoid is disposed on the back side or both sides of a frame constituting a variable winning ball device, and the operating axis of the plunger of the opening / closing solenoid is vertical. It was arranged to be in the direction.

A variable winning prize device is provided with a winning prize port and a decorative member such as a lamp and an LED at the upper portion, and only a collecting path for the prize ball is provided at a lower portion. The frame to be formed and the upper part of the main frame that forms the variable prize ball device form a space, and the space required for the prize ball collection passage disposed at the lower part is extremely small. That is, these space portions were dead spaces. At the bottom, there is provided a collection path for winning balls.

Further, since one side of the plunger of the opening / closing solenoid is in contact with the inner wall of the cylinder of the opening / closing solenoid, when the opening / closing solenoid operates, the two parts which are in contact slide with each other. The operation accuracy is degraded due to the friction of the tire, and a loss occurs. As a result, the plating, coating, and the like applied to the surface of the plunger are worn away due to the above-mentioned erosion, and the surface of the plunger is exposed. The solenoid becomes inoperable. For this reason, the life of the open / close solenoid is shortened, and the variable winning ball device is broken.

[0009]

By the way, in the pachinko machine, the operation accuracy of the opening / closing solenoid varies depending on the initial setting position of the plunger with respect to the opening / closing member. It is desired that the position can be easily maintained in that state. However, in the above-described prior art, no measure has been taken for adjustment at the time of initial setting of the opening / closing solenoid, and the fact is that the above-mentioned technology cannot meet the above demand. In addition, Japanese Utility Model Application No. 59-72234
No. 60-184578 discloses an apparatus in which a boss of an opening / closing solenoid is movably inserted into a hole formed in a mounting plate and has a degree of freedom within the range. However, positioning cannot be easily performed, and the above-mentioned demand cannot be met. Further, Japanese Patent Application Laid-Open No. 58-1057
The device of No. 72 cannot easily adjust the movement and position of the open / close solenoid and cannot meet the above demand.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a winning device for a pachinko machine capable of easily adjusting the movement and positioning of an open / close solenoid and improving operation accuracy. I do.

[0011]

Means for Solving the Problems The present invention, in order to achieve the above object, movable relative to the mounting portion provided with the solenoid mounting member attached to the solenoid to the variable winning ball apparatus, and the mounting portion An elastic body is interposed between the solenoid mounting member and the mounting portion and the solenoid mounting member are connected by screws so that the solenoid mounting member can move with respect to the mounting portion. I do.
