Abstract

PROBLEM TO BE SOLVED: To detect a winning ball securely even if a device uses machinery contact type sensor, use the same to every winning case and reduce a cost of a game machine using many machinery contact-type sensors which are more reasonable than an electronic type switch by reducing a speed of the winning ball. SOLUTION: A projecting part 6 is provided at an almost point of a winning opening 11 for a winning case, further a convex part 9 is provided at a lower part of a wall for a ball passage from the winning opening to a detecting sensor 12 is provided respectively. Thereby, speed of game balls which are fallen in the winning opening are reduced by being meandered. As a result, successive winning balls can be detected securely even if a device uses a machinery contact-type sensor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prize winning device for a pachinko game machine, and more particularly, to a mechanical sensor of a mechanical contact type in which a game ball entering a prize port of a prize case is meandered and decelerated in a ball passage. The present invention relates to a prize winning device for a pachinko game machine, which can surely detect the game.

[0002]

2. Description of the Related Art When a game ball enters a winning opening of a prize case generally called a chucker, it is detected by a detection sensor provided with an electronic measurement control mechanism attached to the back of the game machine to confirm the winning prize ball. The number of prize balls was determined by the number of spheres. The detection sensor includes an electronic sensor of an electronic proximity switch and a mechanical sensor of a mechanical contact type. In general, an electronic proximity switch that reliably detects a signal is often used.

[0003]

However, the electronic sensor of the electronic proximity switch which detects the flow of the winning game ball by a pulse is expensive, and if it is installed for each winning port, the cost of the gaming machine is inevitably increased. Did not. Therefore, when trying to adopt a low-cost mechanical contact type mechanical sensor, it has an operation mechanism that detects the falling of game balls one by one, so if the game balls win consecutively, the game balls continue to enter the winning opening In some cases, the second game ball cannot be detected and responded to, and the mechanical sensor may not be able to reliably detect the ball. Also, if contact vibration called chattering specific to mechanical contacts occurs, it may not be possible to determine whether the cause is due to continuous passage of the game ball as a plurality of contact opening / closing signals or chattering or the cause, and However, if you add an electric filter that removes chattering that is unique to mechanical contact, the contact ball will close for a short time if the game ball passes quickly,
Since there is a similar problem that the signal can not be taken out by the filter and the winning ball can not be detected, electronic sensors that can reliably detect even if there is an economic burden on the manufacturer are often used. It was the current situation.

[0004] Further, since the gaming machines have large and small winning openings and the number of prize balls to be issued are different from each other, the electronic sensor of the electronic proximity switch can be either a mechanical sensor of a mechanical contact type or a mechanical sensor. Attached on the back of the gaming machine, the same number of prize balls are gathered for each ball path of the winning opening where the same number of prize balls come out The detection sensor at one place on the back of the gaming machine detects the number of gaming balls from each winning opening and the number of prize balls It was decided. However, in this method, since the detection sensor is connected to a complicated electronic measurement control mechanism, fraudulent acts may be performed due to the fact that the detection signal etc. is disturbed,
There was also a problem that it was difficult to judge whether the fraud was caused by the player or the detection sensor was wrong, and the fraud could not be identified.

[0005] Further, since it is not possible to detect instantly because the ball passages of the winning opening are gathered in one place on the back surface of the gaming machine, the gaming machine enters the big winning opening and issues a command to start a jackpot or change the probability. It will take time.

It flows down the ball passage cylinder 4 and is collected in a ball collecting case (not shown) on the back of the gaming machine.

[0011]

According to the present invention, the mechanical contact type sensor can be reliably detected by decelerating the winning ball, so that an inexpensive mechanical contact type detection sensor can be used for each winning case, and compared with an expensive electronic switch. This greatly contributes to the cost reduction of a large number of gaming machines. Since it can be attached to each winning case, a prize ball can be detected at the same time as winning, and a command to start a big hit or change the probability can be sent instantaneously. By slowing down and slowing down the flow of the game ball in the winning case, it does not damage the ball passage in the winning opening and the inside of the gaming machine, prevents cracks and cracks, etc. .
