Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a fraudulent ball sorting device for a pachinko machine for separating balls with a smaller diameter than regular pachinko balls.

<Prior Art> A device for removing small-diameter illegal balls by providing a screening hole is known as described in Utility Model Publication No. 28-3510 and Utility Model Publication No. 55-12840.

By the way, in both of these, a long hole with one end open is provided in the running road surface, and this is used as a sorting hole, and after the regular ball fits the lower part into the long hole and travels, it escapes from the long hole through the opening. It becomes like that. The reason why the elongated hole having this opening is used as a sorting hole is because, for example, if the sorting hole is a circular hole, a regular ball will fit into the hole and become unable to travel.

<Problems to be solved by the invention> By the way, with such a configuration, it is necessary that the running road surface can guarantee at least the length of the long hole, and that the long hole must be open at one end. , Therefore, the ball that escaped from the long hole was
−3510, it may fall downward, or
It is necessary to configure it so that it can be moved to a different level running road surface like No. 12840. Therefore, it is necessary to use a specially configured running road surface, which limits its application.

The object of the present invention is to provide a fraudulent ball sorting device for a pachinko machine that does not require the use of long holes in the running road surface as sorting holes.

<Means for solving the problem> The present invention is a ball sorting device that is installed at a direction change position in the ball path of a pachinko machine, and allows balls with a diameter smaller than the outside diameter of regular pachinko balls to pass through. A hole is provided perpendicular to the ball sending direction, and the hole is communicated with the illegal ball discharge path, and the regular balls that are stopped at the ball stop edge around the ball sorting hole are run in the sending direction. This device is equipped with a ball feeding device.

<Function> Pachinko balls flowing down from one direction are stopped at the direction change position, and those of the regular diameter are stopped by the ball stop edge around the ball sorting hole, and their movement is temporarily stopped, and then the balls are stopped by the ball feeding device. The vehicle travels in the other direction. In addition, illegal balls with a small diameter pass through the ball sorting hole and flow down to the illegal ball discharge path without being stopped by the ball stopping edge. Therefore, balls with a small diameter are selectively removed from regular balls.

<Example> The attached drawing shows an application of the present invention to a known ball regulating and feeding device 1 provided on the back of a pachinko machine.

That is, the ball regulation feeding device 1 controls the winning ball receiving channel 2 that communicates with each winning ball receiving hole on the back side of the machine.
It is provided beside the opening end of the inclined passage 3 where the winning balls are collected, and the winning balls on the inclined passage 3 are fed one by one to the guide passage 5 communicating with the winning downspout 4.

The ball regulating and feeding device 1 to which the present invention is applied consists of two stages, upper and lower, with the upper stage having a balance part 7 in which balance balls 6, 6 are enclosed in two left and right chambers, respectively, and facing the open end of the inclined passage 3. A shielding plate 8 is provided at the end thereof to block the open end of the inclined passage 3 when the ball regulating and feeding device 1 is tilted downward.

Further, the lower stage of the ball regulating and feeding device 1 is a ball sorting section 9 having a rectangular chamber shape. That is, the end of the ball sorting section 9 opens toward the inclined passageway 3, and a ball locking wall 10 is provided inside thereof at a distance that can accommodate approximately one ball from the open end. Locking wall 1
The space between 0 and 0 is a feed ball storage chamber 11, and winning balls are supplied one by one from the open end of the inclined passage 3 to the feed ball storage chamber 11. In addition, the ball locking wall 10 includes:
A ball sorting hole 13 through which balls having a diameter smaller than the outer diameter of regular pachinko balls pass is formed and communicates with an illegal ball storage chamber 14 in a ball sorting section 9. A discharge hole 15 is provided on the lower surface of the fraudulent ball storage chamber 14, and communicates with a fraudulent ball discharge path 16 provided at the lower part of the ball regulating and feeding device 1.

Further, the ball regulating and feeding device 1 can be swung by a shaft 17 that passes through the wall surface of the ball sorting section 9.

Furthermore, the lower surface of the ball receiving chamber 11 protrudes to the right and is disposed below the inclined passage 3, forming a locking piece 18.

Therefore, the ball regulating and feeding device 1 normally has the balance of the left and right balance balls 6, 6 of the balance section 7,
It is biased in the counterclockwise direction, and the locking piece 18 comes into contact with the lower surface of the inclined passage 3, so that the ball receiving chamber 11 at the end of the ball sorting section 9 is aligned with the open end of the inclined passage 3. Further, when one regular winning ball a enters the feeding ball storage chamber 11 from the inclined passage 3, the ball tilts around the shaft 17 as shown in FIG. 2 due to the load of the ball, and the locking piece 18 , comes into contact with the support surface of the guide passage 5 to the winning downspout 4, the opening of the guide passage 5 and the sending ball storage chamber 11 coincide, and the winning ball falls from the guide passage 5 into the winning downspout 4. do. At this time, the shielding plate 8 at the end of the balance section 7 coincides with the open end of the inclined passage 3, and the next winning ball a collected in the inclined passage 3
is prevented from flowing out from the open end of the inclined passageway 3.

With this configuration, when an illegal ball b whose diameter is smaller than a regular pachinko ball is supplied from the inclined passage 3 to the feeding ball storage chamber 11, the ball b is
The balls enter the fraudulent ball storage chamber 14 without being retained by the ball stopping edge of the ball retaining wall 10 around the ball sorting hole 13, fall from the discharge hole 15 into the fraudulent ball discharge path 16, and are separated.

In the case of a structure in which a prize ball is supplied every time the ball regulating and feeding device 1 swings when the fraudulent ball b occurs, the ball regulating and feeding device 1 may be supplied with a prize ball depending on the fraudulent ball b. It is necessary to prevent tilting. Therefore, the balance balls 6, 6 are adjusted so that the ball regulating and feeding device 1 does not tilt under the load of the illegal ball b, which is smaller than the normal ball.

The illegal ball discharge path 16 is provided with a sensor 19 that detects the occurrence of the illegal ball b, and upon detection, a sensor 19 is installed to sound an alarm or disable the supply of balls to the firing section. The hitting ball supply hole on the table surface side may be closed or the swinging motion of the firing mallet may be disabled to detect fraudulent play and to prevent continuous use of fraudulent balls b.

In this embodiment, the ball feeding device is provided by the overall configuration of the ball regulating and feeding device 1. In addition, a ball stopping edge that locks regular pachinko balls is constituted by the ball locking wall 10 around the ball sorting hole 13. still,
Instead of the ball locking wall 10, a contact piece capable of locking a regular winning ball a may be suspended from the upper wall in the ball sorting section 9, and its tip may be used as a ball stop edge.

<Effects of the invention> As mentioned above, the present invention provides a ball feeding device at the direction change position of the ball path of a pachinko machine, thereby making it possible to select balls without the need to form long holes on the running road surface. can be done. Further, as in each of the embodiments described above, if a ball feeding device used in an existing pachinko machine is used, the structure can be simplified. Therefore, there are excellent effects such as being able to optimally select fraudulent balls b.
