Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting device for a drive solenoid in a pachinko machine, and is designed to ensure smooth operation of the solenoid over a long period of time.

(Prior Art) A game board of a pachinko machine is provided with various movable bodies, which move when a ball enters a prize opening. As a means of driving the movable body, a solenoid is installed on the back of the game board, and a switch that is turned on when a ball enters the winning slot energizes this solenoid, which attracts the plunger. . FIG. 7 shows this part, and 1 is a prize winning device generally called "Yakumono". This winning device 1 has winning openings 2 and 3.
is provided, and when a ball enters the winning hole 2, the wings 5 of the airplane model 4 rotate around a shaft 6.

The drive mechanism for the blade 5 includes a solenoid 7 provided on the back side of the game board, a plunger 8 inserted into the solenoid 7, a crank lever 9 coupled to the plunger 8, and a crank lever 9.
The shaft part 11 is inserted into the hole 10 in the hole 10, and the hole 1 provided in the other part is inserted.
There is one which is generally composed of a cam 13 through which a shaft 6 on the blade 5 side is inserted through the cam 2, and springs 14 and 15 that apply restoring force to the plunger 8 and crank lever 9. In the figure, 16 is a light emitting diode, 17 is a lamp, and 18 is a switch that detects when a ball enters the winning hole 3.

(Problem to be solved by the invention) In the above-described configuration, when a ball enters the winning hole 2, a switch (not shown) is turned on, the solenoid 7 is energized, the plunger 8 is pulled, and the crank lever 9 moves the cam. Rotation force is given to 13,
The blade 5 will be rotated around the shaft 6, but in this case, the solenoid 7 is immovably fixed to the back of the game board, so the blade 5 will rotate in the postures A and B in Fig. 8. When repeated, the plunger 8 may rub the inside of the solenoid 7 due to the swinging motion of the plunger 8. If the plunger 8 rubs the inside of the solenoid 7 (sections a and b) in this way, there is a problem in that the blade 5 does not move smoothly and the plunger 8 is damaged. The present invention solves this problem.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention has a structure in which a solenoid is swingably supported on a support body.

(Function) If the solenoid is swingably supported in this manner, the solenoid has a degree of freedom in its posture, and therefore, there is no possibility of friction unlike in the conventional solenoid.

(Example) Next, an example of the present invention will be described with reference to FIGS. 1 to 6. 1 and 2 show an embodiment of the present invention. In this case, in order to attach the solenoid 7 to a mounting plate 19 which is a support, a hole 20 provided in the mounting plate 19 is placed on the side of the solenoid 7. It is larger than the boss 21 that protrudes from the hole, and the movement allowance is provided by this portion and the gap d. 22 is Watsusha, 2
3 is a screw, and 24 is a guide. 3 and 4 are similar structures implemented in different locations. In these embodiments, since the hole 20 and the boss 21 are loosely fitted, the solenoid 7 has a degree of freedom within that range, and the intended purpose can be achieved.

The one shown in FIG. 5 is still another embodiment of the present invention, in which a key-shaped guide part 25 is provided on the mounting plate 19, and a fixing part 2 of the solenoid 7 is attached to the guide part 25.
6 is loosely fitted. In this embodiment, by bending the upper and lower ends of the fixed part 26, the solenoid 7
It is necessary to prevent it from falling off. What is shown in FIG. 6 is yet another embodiment of the present invention. In this case, a U-shaped bracket 28 is provided inside the mounting plate 19 that is swingable about a shaft 27, and the upper end of the solenoid 7 is swingably supported by a shaft 29 provided on the bracket 28. . The devices shown in FIGS. 5 and 6 can be expected to have substantially the same effects as those shown in FIGS. 1 to 4.

(Effects of the invention) Since the present invention has the structure and function as explained above, the stress that would cause the plunger to be rubbed can be relieved by the movement of the solenoid, and unlike the conventional one, the plunger It has the advantage of not causing uneven wear or poor movement.
