Abstract

PROBLEM TO BE SOLVED: To always surely feed PACHINKO balls without the danger of fault by preventing an attracting piece from being magnetized like a permanent magnet. SOLUTION: At the terminal part of an inclined beam 3 for letting PACHINKO balls on a shooting ball supply tray flow down while aligning them in one line, a feeding valve 5 is pivotally supported so as to be repeatedly rotated and the PACHINKO balls are fed onto a shooting rail one by one by the repeated rotating actions of the feeding valve by attracting an attracting piece 9 integrally provided on the feeding valve with an electromagnet 10. Concerning such a shooting ball feeding device, a stopper 15 is provided for confronting an iron core 11 of the electromagnet and the attracting piece of the feeding valve while avoiding the direct contact and keeping a gap (g).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a firing ball for feeding pachinko balls on a hitting ball supply tray provided on the front of a pachinko game machine one by one to a firing rail in conjunction with the movement of a hammer of a hitting ball firing device. The present invention relates to a feeding device.

[0002]

2. Description of the Related Art As is well known, a launching ball feeder of a pachinko game machine arranges a large number of pachinko balls placed on a hitting ball supply tray by a player through an inclined gutter to align them in a row. The pachinko balls are fed one by one to the firing rail by repeatedly rotating the feed valve in conjunction with the movement of the hammer.
As shown in -150985 and the like, a structure in which the feed valve is repeatedly rotated by suctioning the feed valve by an electromagnet is known.

[0003]

By the way, in the launching ball feeder having a structure in which the feed valve is repeatedly operated by attracting the feed valve by the electromagnet as described above, the operation of the feed valve causes the magnetic force of the feed valve to be transferred to the iron core of the electromagnet. Since the pieces come into contact repeatedly, the magnetic pieces gradually become magnetized and become permanent magnets, so even if the current of the electromagnet is cut off, they will not be able to separate from the iron core due to the magnetic force and will not be able to feed pachinko balls normally There was a fear.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems and to provide a launching ball feeder for a pachinko game machine which can always operate smoothly.

[0005]

In order to achieve the above object, a launching ball feeding device for a pachinko game machine according to the present invention is provided with a feed valve at the end of an inclined gutter for aligning and flowing down pachinko balls on a hitting ball supply tray in a line. The feed valve is rotatably supported and the magnetically attached piece integrally provided with the feed valve is attracted by an electromagnet to thereby repeatedly rotate the feed valve to feed the pachinko balls one by one onto the firing rail. The launching ball feeding device is characterized in that an impact piece is provided for avoiding direct contact between the iron core of the electromagnet and the magnetically attached piece of the feed valve so as to face each other with a gap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a launching ball feeder according to the present invention, 1 is a hitting feed tray provided on the front of a pachinko game machine, 2 is a plastic casing constituting the launching ball feeder, Is an inclined gutter formed for aligning a large number of pachinko balls 4 placed on the hitting ball supply tray in one row and causing them to flow in the direction of the arrow. Numeral 5 is a plastic feed valve provided at the end of the inclined gutter 3. As shown in FIG. 3, the feed valve 5 has a pair of support shafts 6 integrally formed on substantially both sides of the intermediate portion. A stopper 7 is formed at the upper end, a holding portion 8 is formed at the front of the intermediate portion, and a magnetic attachment piece 9 made of a plate-like ferromagnetic metal such as an iron plate is integrally inserted at one side of the lower end. Is molded. By pivotally supporting the support shaft 6, the feed valve 5 is provided at the end of the inclined gutter 3 so as to be able to rotate repeatedly.

Reference numeral 10 denotes an electromagnet formed by winding an electromagnetic coil around an iron core 11. The electromagnet 10 attaches the iron core 11 to the magnetic piece 9.
And is fixed to the casing 2 so as to face. Also,
Reference numeral 12 denotes a game board, 13 denotes a firing rail, and 14 denotes a hammer of a hit ball firing device.

[0008] Thus, reference numeral 15 denotes the electromagnet 1 around the iron core 11.
The electromagnet 10 is energized and the magnetic piece 9 is attracted to the iron core 11. 15, the iron core 11 and the magnetically attached piece 9 do not come into direct contact with each other;
It is provided to allow a gap g of about millimeters to be formed.

When the electromagnet 10 is not excited, as shown in FIGS. 4 and 5, the feed valve 5 is in an upright position, and the stop piece 15 is inclined. Since the pachinko ball 4 is standing upright at the end of the pachinko ball 3, the flow of the pachinko ball 4 is stopped. Then, when the player operates the steering wheel to operate the hitting ball firing device and repeatedly rotates the hammer 14, a current is supplied to the electromagnet 10 in synchronization with the operation to excite the electromagnet, and FIG. 6 and FIG. As shown, the magnetically attached piece 9 is attracted to the iron core 11 and the feed valve 5 is rotated in a backwardly inclined manner with the support shaft 6 as a fulcrum. Then, when the excitation of the electromagnet is released and returns to the state of FIGS. 4 and 5 by its own weight, the pachinko ball 4 is fed onto the firing rail 13. Therefore, each time the excitation and the demagnetization of the electromagnet 10 are repeated, one pachinko ball can be fed onto the firing rail 13 one by one.

In this launching ball feeder, the electromagnet 1
When the magnetically attached piece 9 is attracted to the iron core 11 of the
The magnetized piece 9 so that there is always a gap g between the iron core 11 and the magnetically attached piece 9, there is no possibility that the magnetically attached piece 9 is magnetized like a permanent magnet, and the electromagnet 10 is demagnetized. When it does, its own weight wins and the pachinko ball can be reliably fed.

In this embodiment, the stoppers 15 are provided on the case of the electromagnet 10. However, such stoppers may be protruded from the casing 2, and may be provided on the periphery of the magnetic piece 9. It may be provided. Incidentally, in another embodiment of the present invention shown in FIG. 8, the support shaft 6 of the feed valve 5 is provided horizontally, and when the electromagnet 10 is excited, the feed valve 5 repeatedly rotates in a vertical plane. In this case, the magnetically attached piece 9 is inserted into the plastic constituting the feed valve 5, and the thickness of the magnetically attached piece 9 functions as a stop piece so that the iron core 11 is formed.
A proper gap is always formed between the magnetically attached piece 9 and the magnetic piece 9.

[0012]

As described above, according to the present invention, in a launching ball feeder which repeatedly rotates a feed valve by attracting a magnetically attached piece provided integrally with a feed valve by an electromagnet, the iron core of the electromagnet is Since the stop piece is provided for avoiding direct contact with the magnetic piece and facing each other with a gap, the magnetic piece is not magnetized like a permanent magnet, and there is no risk of failure due to this. This has the beneficial effect of ensuring that pachinko balls can always be delivered.
