Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a solenoid drive device used for moving a prize opening, etc. in a pachinko machine.

[Prior Art] In a pachinko machine, a solenoid increases the interest of the pachinko game by widening the prize opening provided on the game board for a certain period of time to increase the chance of winning a ball, or by changing the flow path of the ball. It has traditionally been widely used for this purpose. In that case, if the solenoid is left energized for a long time, it may overheat and burn out.

[Object of the Invention] Therefore, the present invention aims to prevent the solenoid in the pachinko machine from overheating even when it is energized for a long time.

[Means for Achieving the Object] In order to achieve the object, the solenoid drive device in the pachinko machine according to the present invention includes a micro switch that switches the drive voltage of the solenoid between a relatively high voltage and a relatively low voltage. Alternatively, the solenoid is provided opposite to an operation interlocking member connected to the plunger, and when a high voltage is applied to the solenoid and the plunger of the solenoid is activated, the micro switch changes the driving voltage of the solenoid from a high voltage to a low voltage. This feature is characterized in that it can be switched to.

[Embodiment] In this embodiment, the present invention is applied to drive a solenoid for a ball flow path changing device. First, the structure of the ball flowing path changing device will be explained in detail.

In the figure, 1 is a horizontally elongated rectangular mounting board, and the shaft hole 2 is centered on the upper back surface of the mounting board 1.
A plurality of shaft supports 3 are bored at regular intervals in the lateral direction, and horizontally elongated guide holes 4 are provided on the lower side parallel to the side edges. Reference numeral 5 denotes a partition plate located on the front surface of the mounting board 1, in which a protruding shaft 6 provided at the upper end is fitted into the shaft hole 2 of each shaft support 3 and rotatably supported. It is formed into an L-shape in plane by a support piece 5a corresponding to the support piece 5a and a side piece 5b protruding from one side edge of the support piece 5b to the front side, and one piece is formed by the spacing between the adjacent side pieces 5b. A flow path 7 through which the balls can pass vertically is formed in a horizontal line. Further, a pin 8 is provided at the lower end of the support piece 5b of each partition plate 5 so as to protrude from the back side of the mounting board 1, facing the guide hole 4.

Reference numeral 9 denotes an actuating plate which is movable laterally along the guide hole 4 on the back surface of the mounting board 1, and pivotally connects the pins 8 of each partition plate 5.
A horizontally pulling spring 10 is attached to one of the pins 8, and the actuating plate 9 is biased so that each partition plate 5 normally maintains the vertical position shown by the solid line in FIG. Reference numeral 11 denotes a solenoid serving as a driving means, which is fixed to the back surface of the game board a via a mounting plate 12. The tip of the plunger 13 of the solenoid 11 and one end of the actuating plate 9 are connected to each other by a shaft 14 at the center of the solenoid. The connection is made using the motion interlocking member 15.

FIG. 5 shows an example in which this flow path converting device is attached to a game board a. That is, this flow path converting device is installed on the left and right sides of the approximate center of the game board a, and the prize openings 16 are arranged directly below each flow path 7' of the flow path 7 formed by each partition plate 5. The obstacle nail 17 is planted above the flow path 7' in which the prize opening 16 is arranged.

Therefore, under normal conditions, the solenoid 11 is demagnetized and each partition plate 5 is placed vertically as shown by the solid line in FIG. The hitting balls passing through are guided downward as they are, and the hitting balls passing through each flow path 7' enter the winning opening 16 and win a prize. However, in this case, the obstructing nails 17 prevent the balls from easily passing through each flow path 7', making it difficult for the balls to enter the winning opening 16.

In this state, when the solenoid 11 is energized and the plunger 13 is pulled, the actuating plate 9
moves laterally against the spring 10, and each partition plate 5
rotates about the shaft 6 at the upper end as a fulcrum as shown by the chain line in FIG.
Let's face it. Therefore, when the hit balls pass through each of the flow paths 7, all of the hit balls enter the winning hole 16 and become winning balls, and the chances of winning a prize are very high.
When the solenoid 11 is demagnetized, the actuating plate 9 moves back to the solid line position in FIG. return.

Reference numeral 18 denotes a micro switch provided opposite the operation interlocking member 15, and the micro switch 18 is connected to the solenoid 11 as shown in FIG.
When the operating protrusion 19 of the micro switch 18 is pressed by the operating member 15, the micro switch 18 is operated to change the driving voltage of the solenoid 11 from 24 volts to 10 volts. It is something that can be switched. Reference numeral 20 denotes a transistor that is turned on in response to a command from the microcomputer to excite the solenoid 11. When the base voltage increases in response to a command from the microcomputer, conduction occurs between its emitter and collector, and the voltage is applied to the solenoid 11 via the microswitch 18. is being applied. Note that 21 is a diode connected in parallel with the solenoid 11 to prevent reverse current to the transistor 20.

In the solenoid drive device configured in this way, when the transistor 20 is turned on by a command from the microcomputer, the microswitch 18 is connected to the solenoid 11 to the 24 volt side.
An operating voltage of 24 volts is applied. Then, the solenoid is energized by this voltage and the plunger 1
3 is pulled, the motion interlocking member 15 tilts as shown by the dashed line in FIG. Therefore, the operating protrusion 19 of the micro switch 18 is pressed by the operation interlocking part 11, and the contact of the micro switch 18 is switched from the high voltage side to the low voltage side, and an operating voltage of 10 volts is applied to the solenoid 11. . The flow path changes by driving the solenoid 11, and the flow of balls can be varied in a wide area in the lateral direction of the game board.

Then, when the transistor 20 is turned off by a command from the microcomputer, the solenoid 11 is demagnetized and the operation interlocking member 15 returns to its original state due to the elasticity of the spring 10, so the contact of the microswitch 18 also returns to its original state and is connected to the 24 volt side again. .

[Effects of the Invention] As described in the embodiments above, in the solenoid drive device of the present invention, when the solenoid starts operating, a relatively high voltage is applied to the solenoid and the solenoid is strongly excited. Even if the movement is heavy, sufficient power can be obtained to move the solenoid. On the other hand, when the movement interlocking member moves, a micro switch is activated and the voltage is switched to a low voltage, so excessive current will not flow to the solenoid. Even if it is energized for a long time, it will not overheat or burn out. Therefore, the present invention is extremely effective as a means for preventing overheating and burnout of solenoids in pachinko machines and at the same time reducing power consumption.
