Description

[Detailed description of the invention] The present invention operates a hit ball winning device, which is attached to the surface of the game board and changes the state of accepting balls, by energizing a solenoid, so that balls are easily received within a certain period of time. This relates to an electromagnetic actuating device for a pachinko machine for changing the state of the machine, and is characterized by preventing overheating and burning out of the solenoid and eliminating wasteful power consumption.

Conventionally, this type of device continuously energizes the solenoid during the time period that changes the ball winning device to a state where it is easy for balls to enter, which not only consumes unnecessary power but also has the disadvantage of burning out the solenoid. . Furthermore, if a large solenoid is used to avoid burning out the solenoid, it is expensive and consumes more power, and furthermore, it takes up a lot of space, making it impracticable.

The present invention aims to eliminate such conventional drawbacks.
It is intended to serve one purpose.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a mounting plate, on the surface of which a first solenoid 2 and a second solenoid 3 are arranged so as to face each other in different vertical positions. These solenoids 2 and 3 are fixed to a mounting frame piece 4 protruding from the mounting plate 1 with screws 5 .
Reference numeral 6 denotes a substantially shaped locking member located between the first solenoid 2 and the second solenoid 3, whose bent portion is pivotally connected to a support shaft 7 fixed to the mounting plate 1, and the second solenoid
In the figure, its left end is connected to the plunger 9 of the first solenoid 2 with a pin 10.

An engagement element 14 having an engagement slope 14a is fixed to the upper end of the plunger 13 of the second solenoid 3. Further, the plunger 13 is normally urged upward by a spring 15 wound around the plunger 13. Further, the lower end of the plunger 13 is integrally provided with an operating rod 16 that projects downward when the plunger 13 moves downward.

The locking member 6 is normally rotated counterclockwise in FIG. 2 by a spring 11 that urges the plunger 9 of the first solenoid 2 downward, and the locking member 6 is rotated counterclockwise in FIG. A stopper piece 12 protruding from the mounting plate 1 and projecting below the interlock 14 limits its rotational position to a certain level. In the figure, 17 is a circular plate fixed to the lower end of the working rod 16, 18 is a mounting hole drilled in the mounting plate 1, and 1
9 indicates lead wires drawn out from the solenoids 2 and 3.

This electromagnetic actuating device configured as described above is constructed by, for example, fixing the mounting plate 1 with screws or the like to the back surface of the game board on which the ball winning device is attached on the surface, although not shown in the drawings. When the plunger 13 of the solenoid 3 moves downward, the circular plate 1 of the operating rod 16
7 is used in conjunction with the ball winning device to change it so that it is easier for the ball to enter.

Next, the operation of this electromagnetic actuator will be explained. Second
In the state shown by the solid line in the figure, when the second solenoid 3 is momentarily energized and its plunger 13 is attracted downward against the spring 15, the engager 14 contacts the locking member 6 from above in the process. , the locking member 6 is rotated clockwise about the support shaft 7 as shown by the chain line in FIG. 2 against the force of the spring 11. When the locking member 6 comes out of contact with the engaging element 14, it returns to its original position by the action of the spring 11.
As shown in FIG. 3, the lower end of the engaging portion 6a is engaged with the engaging slope 14a of the engaging element 14 to hold the plunger 13 in the operating position.

In this state, when the first solenoid 2 is momentarily energized and its plunger 9 is attracted upward against the spring 11, the locking member 6 is rotated clockwise around the support shaft 7 as shown by the chain line in FIG. direction, and the engagement of the engagement element 14 by the engagement portion 6a is released. Therefore, the plunger 13 of the second solenoid 3 returns to its original position as shown by the solid line in FIG. Rotate 6 to return to the original position.

In summary, according to the present invention, even if the second solenoid 3 for changing the hit ball winning device to a state where balls can easily enter is demagnetized and its plunger 13 attempts to return to its original position by the action of the spring 15, 1
The locking member 6 connected to the plunger 9 of the solenoid 2 keeps it in the operating position. In other words, by momentarily energizing the second solenoid 3, the solenoid 13 can be held in the operating position of the ball winning device for a desired period of time, completely preventing the solenoid from burning out due to continuous energization as in the past. It can be done. In addition, the engagement can be immediately released by momentarily energizing the first solenoid 2 and moving the locking member 6, so that the desired purpose can be reliably achieved with a small amount of power consumption. Can be done.

Moreover, the structure is extremely simple, there are few failures, and since it is rationally arranged on a single mounting plate, it can be easily assembled even in narrow spaces without taking up much space, and has great practical effects. be.
