Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball supply device that feeds pachinko balls one by one to a shooting position on a guide rail in conjunction with the shooting operation of a ball hammer.

[Prior Art] Conventionally, for example, Japanese Utility Model Publication No. 1987-59 discloses a means for feeding pachinko balls one by one to a shooting position of a guide rail in conjunction with the shooting operation of a batting mallet. To explain this based on FIG.
The interlocking lever 103 is swung along with the swiveling of the ball, thereby operating the ball feeding member.

[Problems to be solved by the invention] According to the above-mentioned conventional technology, since the interlocking lever and the batting mallet are brought into direct contact to feed the ball, it will not operate smoothly unless the mounting positions of both are accurate. .

In addition, if dirt adheres to the contact surface between the two after long-term use, it will become less slippery and cause problems in operation.
Furthermore, there was even a risk of damage due to wear.

[Means for Solving the Problems] Therefore, the present invention includes a batting mallet 6 that launches pachinko balls toward the gaming section 4a of the gaming board 4, and an interlocking lever 9b that swings as the batting mallet 6 launches. A ball feeding member 9 feeds pachinko balls supplied from the ball tray 10a on the front of the pachinko machine 1 to the guide rail 5 one by one.
In the batted ball supply device A of the pachinko machine 1, permanent magnets 20 are respectively fixed on opposing surfaces of the interlocking lever 9b and the batting mallet 6, and both permanent magnets 20 have the same polarity facing each other. This problem was solved by configuring the system so that the two elements would repel each other.

[Operation] Due to the repulsive force between the permanent magnets 20, the batting mallet 6 and the interlocking lever 9b always maintain a distance from each other, so that the batting mallet 6 and the interlocking lever 9b swing as the batting mallet 6 swings without mechanical contact. Then, the ball feeding member 9 operates to feed the pachinko balls one by one to the guide rail 5.

[Example] An example of the present invention will be described below with reference to the drawings.

As is well known, the pachinko machine 1 has a game board 4 installed in the back of the window hole 3 of the front frame 2, a guide rail 5 laid on the game board 4 to form a circular game part 4a, and further The top of the swingingly supported ball mallet 6 faces the launch start end 5a of the guide rail 5, and the swinging action of the ball mallet 6 causes the pachinko balls at the launch start end 5a to be bounced, thereby creating the game part 4a. It was designed to be sent to

The supply of pachinko balls to the starting end 5a of the guide rail 5 is performed by the ball supply device A shown in FIG. The ball supply device A includes a box-shaped case body 7, a rectifying gutter 8, and a ball feeding member 9. The rectifying gutter 8 communicates with the spherical plate 10a of the front plate 10 at its upper end, and with the firing start end 5a of the guide rail 5 at its lower end. In addition, the ball feeding member 9
The ball feeding arm 9a is composed of a combination of a ball feeding arm 9a and an interlocking lever 9b, and the ball feeding arm 9a has a substantially horizontal lever 11 whose middle part is pivoted inside the case body 7, and a long hole is formed in the end on the rectifying gutter 8 side. A valve part 13 is provided between the long hole 12 and the shaft attachment part, and a weight 14 is provided at the opposite end of the lever 11. The valve portion 13 is normally projected to the downstream end of the rectifying gutter 8 by the action of the weight 14,
This valve part 13 is designed to stop the pachinko balls flowing down on the rectifying gutter 8 (solid line in Figure 2). On the other hand, the interlocking lever 9b has an inverted L-shape, and its corner is pivoted to the game board 4 side so that it can swing freely. 12. A permanent magnet 18 is fixed to the downwardly extending hanging arm 17.

Further, an arm rod 19 is extended to the ball hammer 6, and a permanent magnet 20 is fixed to the arm rod 19 on a surface facing the permanent magnet 18 of the interlocking lever 9b.
Both permanent magnets 18 and 20 have their north poles facing each other so that they repel each other.

Next, the effect will be explained.

The pachinko balls in the ball tray 10a flow down the rectifying gutter 8, but because the valve portion 13 of the ball sending arm 9a projects to the end of the rectifying gutter 8, they stop there.

Then, when the ball mallet 6 is tilted as shown by the chain line in FIG.
b swings as shown by the chain line in the figure, and the ball feeding arm 9a
The tip of the valve part 13 moves downward, and the pachinko ball rides on its upper surface. Next, when the ball hammer 6 moves back, the interlocking lever 9b moves the weight 14 of the ball feeding arm 9a.
The valve part 13 moves back due to the action of the valve part 13, and the pachinko ball on its upper surface is sent out to the firing start end part 5a. Thereafter, pachinko balls are supplied one by one in response to the operation of the ball mallet 6.

[Effects of the invention] As explained above, according to the pachinko ball feeding device A of the invention, the ball hammer 6 and the ball feeding member 9 are interlocked by the repulsive force of the permanent magnet 20 and the magnetic body 18, so that both Even if there is a slight error in the mounting position, the ball can be fed without any problem. Therefore, there is a practical benefit in that the installation work of the batted ball supply device A to the pachinko machine can be performed extremely easily.

Furthermore, since the batting mallet 6 and the ball feeding member 9 can be operated without mechanical contact, there is no increase in resistance due to adhesion of dirt, etc., and there is no wear between the two, resulting in stable operation over a long period of time. Can be used.
