2. Description of the Related Art Conventionally, there is a variable prize winning device capable of electrically operating a pair of opening / closing members to convert a pachinko ball into an easy-to-accept state and a difficult-to-accept state. More specifically, in the variable winning device, a ball entrance is opened in a mounting board attached to the game board surface, and the ball entrance is sandwiched in front of the mounting board, and it is difficult to stand up and accept pachinko balls. A pair of openable and closable members are disposed, which can be tilted in a letter shape and converted into a state in which the pachinko ball can be easily received. On the other hand, on the back side of the mounting substrate, a solenoid in which a plunger advances and retreats horizontally in the front-rear direction, a solenoid crank fixed to the tip of the plunger and provided with an engagement recess whose lower end is opened, and a base end side, An engaging pin that engages with the engaging concave portion is protruded and connected to a solenoid crank and freely rotates up and down, and a distal end of a main rod extending forward from a base end is connected to each of the opening and closing members. And a crank member. Then, as the plunger advances due to the demagnetization of the solenoid, the tip of the main rod of the crank member is rotated downward to hold both open / close members upright, and the tip of the crank member is retracted due to the retraction of the plunger due to excitation of the solenoid. The part is turned upward to tilt both opening and closing members in an inverted figure of eight.

[0003]

In the variable winning device, the opening and closing member is electrically operated by a solenoid, and is fixed to the opening and closing member and the crank member or to the tip of the crank member and the solenoid plunger. Each is connected to a solenoid crank.
Therefore, when the solenoid is demagnetized and the up-and-down opening and closing member is forcibly tilted, the crank member rotates upward with this, and the solenoid crank is pushed further, and the plunger is attached with the coil spring. In this configuration, the opening / closing member retreats against the force, and as a result, the opening / closing member tilts in an inverted C shape. For this reason, for example, during a game, a player crawls a small-diameter piano wire or the like on the game board surface from a gap of a glass door frame covering the front of the game board, forcibly opens a pair of opening and closing members, and a hit ball enters. There has been a problem that an illegal operation is performed in an attempt to obtain a large number of winning balls in an easy-to-understand state.

Accordingly, the present invention has been made to solve the above-mentioned problem, and a variable prize of a pachinko machine in which a pair of opening / closing members are prevented from opening by operations other than demagnetization of a solenoid to prevent fraudulent acts. It is intended to provide a device.

[0005]

In order to achieve the above object, a variable winning device of a pachinko machine according to the present invention is provided with a pachinko ball standing upright on a front side of a mounting board and inclining in an inverted C-shape.

The distal end of the crank member accompanies advance of the plunger due to demagnetization of the solenoid. To open and close both open / close members, and raise the tip of the crank member with the retraction of the plunger due to the excitation of the solenoid. In the variable winning devices of the pachinko machine so as to tilt the two closing members is rotated in the reverse truncated reverse V shape, and the solenoid crank and the crank member,
Only when the solenoid is energized and the solenoid crank retreats a predetermined length is the crank member connected by engagement means for rotating the tip thereof upward, and the solenoid crank is connected to the solenoid crank when the solenoid is demagnetized. A structure is provided which is located above the member to prevent unnecessary upward rotation of the member and to release the blocking before the solenoid is excited to retract the solenoid crank by a predetermined length.

The engaging means comprises a downwardly engaging recess provided on the solenoid crank and an engaging pin projecting from the shaft support of the crank member and engaging with the engaging recess. It is preferable that a main rod connected to each of the opening / closing members extends forward from the shaft support, and a cut-out portion is provided on an upper surface of the main rod, into which a holding piece is fitted when the solenoid is demagnetized.

With this arrangement, when the solenoid is excited during the game, the holding piece also retreats until the solenoid crank retreats by a predetermined length, thereby enabling the main rod to rotate upward. The opening / closing member is tilted in an inverted C-shape to convert the pachinko ball into a state where it can be easily received. Therefore, when the solenoid is demagnetized, even if an attempt is made to forcibly open the pair of opening and closing members, the main rod is supported by the holding piece before the plunger retreats, and its upward rotation is prevented. The opening and closing member is not opened unnecessarily, thereby preventing fraud.
