Description

The present invention relates to an improvement of a variable winning device that opens and closes a blade member when a specific condition is satisfied.

2. Description of the Related Art Pachinko machines equipped with a movable prize device having a movable surface component called a feather are conventionally known. The blade is composed of a pair of blade members that rotate between an open posture and a closed posture using an electric actuator such as a solenoid or a motor as a drive source. Then, when a game ball is won at a predetermined start winning opening, the solenoid is operated to open the pair of blade members once or twice, and the game ball flowing down the game board surface is captured to make a variable prize. Guide into the device. Further, when the solenoid is turned off, the blade member is closed so that a game ball cannot be won (Patent Documents 1 and 2).
However, in the conventional blade, when the electric actuator is in the OFF state, if the blade member at the closed position is forcibly pressed in the opening direction by hand, the electric actuator operates in the opening direction. It can be opened. Therefore, for example, if a wire or the like is inserted into the glass frame to open the blade member, it can be easily opened, and a prize ball can be obtained illegally.
In the winning device according to Patent Document 3, a lock mechanism that prevents the movable blade piece (blade member) from being opened when the electric actuator is OFF has been proposed as a technique for preventing such an illegal act. According to this lock mechanism, it is possible to effectively prevent the act of illegally trying to obtain a prize ball by opening the movable blade piece, but the interlocking interposed between the electric actuator such as a solenoid and the movable blade piece Since the thickness of the members (including the lock mechanism) in the front-rear direction exceeds the thickness of the solenoid, etc., the overall thickness of the winning device increases, increasing the size of the gaming machine and lowering the degree of freedom of layout of adjacent components and units. The problem has arisen. The reason why the thickness of the interlocking member including the lock mechanism exceeds the thickness of the solenoid is that the number of parts of the interlocking member is six (two actuating members, lock member, mooring member, crank, pin). There is.

Next, the configuration and operation of the variable winning device will be described with reference to FIGS.
The variable winning device A is a board component that is provided on the front surface (game area 1a) of the game board 1 and opens when a specific condition is satisfied.
The variable prize-winning device A drives two blade members 16 that are spaced apart from each other in the left-right direction while being rotatable between a closed position and an open position, and is disposed on the back side of each blade member 16. And a blade member drive mechanism (drive mechanism) 40.
In the illustrated embodiment, two blade members spaced apart from each other as the blade member 16 are shown. However, the separating direction is not limited to the left and right, and may be up and down, oblique directions, and the like. The number of blade members is not limited to two. One sheet or three or more sheets may be used.

The drive mechanism 40 has a base 42 fixed by a pivot shaft 18 projecting rearward from each blade member 16 and a pin projecting in parallel with the pivot shaft 18 on a projecting portion 43 projecting outward from the base portion. (Engagement part) Actuating piece 41 having 44, turning member 50 pivotally supported on base end 52 so as to be rotatable about shaft 51 parallel to turning shaft 18, and turning member 50 By locking the plunger 15a to the locked portion 53 provided near the shaft portion 51, the rotating member 50 is locked in the locking direction (the closing direction of the blade member = first time ) by the protruding and retracting of the plunger. And a solenoid 15 that rotates in the unlocking direction (opening direction of the blade member = second rotating direction) .
The rotating shaft 18 and the plunger 15a are connected by a connecting mechanism. The coupling mechanism is provided at one end portion, is located on the second rotation direction side from the rotation shaft 18, can be rotated around a shaft portion 51 parallel to the rotation shaft, and in a direction orthogonal to the rotation shaft. It consists of the extending rotation member.
The rotating member 50 has a guide hole (engaged portion) 55 for loosely fitting the pin 44 of the operating piece at the tip (tip portion), and from a portion between the guide hole 55 and the locked portion 53. It has a lock piece 56 projecting toward the operating piece 41.
The actuating piece 41 includes a locked portion 45 that is unable to rotate the actuating piece 41, the rotating shaft 18, and the blade member 16 by engaging with the lock piece 56.

The solenoid 15 always urges the plunger 15a in a protruding direction by a spring (not shown), and retracts the plunger against the spring when the solenoid body is energized. The plunger 15a is engaged with the rotating member 50 in the locked portion 53, and when the solenoid is turned off and the plunger protrudes, the rotating member 50 moves downward with the shaft portion 51 as the center as shown in FIG. Rotate. At this time, the pin 44 projecting from the tip of the rotating member is fitted into a recess 55 a provided in the upper part of the inner periphery of the guide hole 55.
Further, when the solenoid is turned on and the plunger is retracted, the rotating member 50 rotates upward about the shaft portion 51 as shown in FIG. 7, and the pin 44 is detached from the recess 55a.

When the rotating member 50 is held at the locked position shown in FIG. 6 by the solenoid 15 and the lock piece 56 is engaged with the locked portion 45, the pin 44 is provided at the upper inner periphery of the guide hole 55. An operation of fitting in the recess 55a and rotating the blade member 16 in the opening direction is prohibited. For this reason, even if the blade member 16 is pressed in the opening direction, the opening operation does not occur. On the other hand, when the turning member 50 is turned in the unlocking direction by the solenoid, the lock piece 56 is turned in the unlocking direction (upward in FIG. 7) away from the locked portion 45 around the shaft portion 51. This allows the pin 44 to escape from the recess 55a of the guide hole and rotate the blade member 16 in the opening direction.
Note that the function of locking or releasing the operating piece 41 is realized only when the lock piece 56 engages or releases the locked portion 45, and the pin 44 is placed in the recess 55a. The operation of mating and unmating is not essential for the lock and unlock functions.

More specifically, the distal end portion of the lock piece 56 contacts the distal end portion of the locked portion 45 when the rotating member 50 is pushed downward by the plunger 15a as shown in FIG. On the other hand, while the rotation member 50 is pulled upward by the plunger 15a as shown in FIG. 7, the opening direction of the blade member 16 is retracted from the movement path of the distal end portion of the locked portion 45 as shown in FIG. Is allowed to rotate.
That is, when the rotating member shifts from the locked state shown in FIG. 6 to the unlocked state shown in FIG. 7, the rotating member 50 is centered on the shaft portion 51 in the releasing direction (reverse to FIG. 6B). In order to rotate in the clockwise direction, the bottom surface 55b of the guide hole 55 pushes up the pin 44 to open the blade.
In addition, when the blade is opened by hand or the like in the locked state shown in FIG. 6, a force in the counterclockwise direction of FIG. The locked portion 45 is locked by the tip of the lock piece 56, and the blade cannot be opened.

As described above, in the present invention, the blade mechanism is opened and closed by the driving force from the solenoid by sequentially assembling the drive mechanism 40 including the two parts 41 and 50 to the rotating shaft 18 extending from the blade member, and the blade member is in the closed position. Since the lock mechanism that locks was also constructed, the thickness of the drive mechanism could be reduced by greatly reducing the number of parts.
In particular, since the operation piece 41 and the rotation member 50 can be configured to be positioned within the width of the solenoid 15 (does not protrude outside the width), the entire variable winning device as shown in FIG. It has become possible to reduce the thickness, making it possible to reduce the thickness of pachinko machines and improve the degree of freedom in layout between components.
As described above, according to the present invention, the drive mechanism interposed between the solenoid and the rotating shaft of the blade member is composed of the two parts of the operating piece and the rotating member, so that the thickness and size can be reduced by reducing the number of parts. It is possible to reduce the number of assembly steps, reduce the cost, and free the layout.
