Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball passage detection device for detecting the passage of a pachinko ball hitting a game board of a pachinko game machine, and a pachinko game machine equipped with the device.

[0002]

2. Description of the Related Art In a conventional pachinko game machine, a guide frame is provided on an outer peripheral portion of a board surface, and a guide rail is provided inside the guide frame to guide a punched pachinko ball to a central game surface. Ball passage is formed. The pachinko ball that has jumped out to the game surface through the ball passage enters the winning opening while flowing down the game surface, or is taken into the out opening at the bottom of the game surface.

[0003] In this kind of pachinko gaming machine, since a large number of nails are arranged on a board at a high density, pachinko balls struck on the board have a gap between the nails and other members. There is a risk that the subsequent pachinko balls will be caught in between them, and that a plurality of pachinko balls will rush into the out mouth, causing a jam.

[0004] Some of the players are fraudulent players called Goto. For example, a glass door covering the board is illegally opened, and a large number of pachinko balls are forcibly inserted into one of the winning ports. Misconduct such as insertion has been performed.

[0005] Therefore, the applicant has recently determined the number of pachinko balls hitting the game surface, the number of winning pachinko balls entering the winning opening, and the number of pachinko balls collected in the out opening. A method has been proposed in which counting is performed, and the presence or absence of clogging of balls or improper behavior in the game is automatically detected depending on whether the sum of the number of winning balls and the number of outgoing balls matches the number of hitting balls.

In order to count the number of hit balls, the number of winning balls, and the number of out balls, sensors for detecting pachinko balls are provided in a ball passage, a winning port, and an out port, respectively, and each time the sensor performs a detecting operation. , The count value is incremented. In particular, regarding the counting of the number of hit balls, two sensors are arranged upstream and downstream of the ball passage so that pachinko balls that return to the ball passage after passing the sensor mounting position are not erroneously detected as passing balls. After the downstream sensor performs the detection operation, the count value is incremented by one when the upstream sensor performs the detection operation, and the count value is decremented by one when the sensor performs the detection operation in the reverse order. I am trying to increment.

[0007]

However, in the above-mentioned method, since the increment or decrement must be performed in accordance with the order in which the two sensors perform the detecting operation, the mechanism of the counter for counting becomes complicated. In addition, there is a problem that the counting process takes time.

The present invention has been made in view of the above-mentioned problem. A return prevention device for preventing return of a pachinko ball from a game surface to a ball passage is provided in a ball passage, and a vicinity of the return prevention device is provided. An object of the present invention is to provide a pachinko ball detection sensor at a position, thereby simplifying the process of recognizing a passing ball while reliably launching a pachinko ball on a game surface.

[0009]

According to a first aspect of the present invention, there is provided a pachinko ball passage detection device, wherein a guide rail is provided inside a guide frame on an outer peripheral portion for guiding a punched pachinko ball to a central game surface, On the ball path between the guide frame and the guide rail, return of the pachinko balls from the ball path to the game path is allowed, but return of the pachinko balls from the ball path to the game path is prevented. And a pachinko ball detection sensor for detecting the passage of a pachinko ball is provided near the return prevention tool.

In the pachinko ball passage detecting device of the second aspect, in addition to the configuration of the first aspect, the pachinko ball is allowed to protrude to the game surface on the side of the pachinko ball protruding with respect to the return prevention tool. A second return preventing device for preventing return of the pachinko ball to the ball passage is provided.

According to the third aspect of the present invention, the pachinko game machine includes:
A pachinko ball passage detection device according to claim 1 or 2 is provided.

[0012]

Since the pachinko ball is prevented from returning from the game surface to the ball passage by the return preventing device, the passage of the pachinko ball can be detected only by the detection operation of one sensor near the return preventing device. it can. This greatly simplifies the passing ball detection process as compared to the case where pachinko ball passing is detected by two sensors.

According to the second aspect of the present invention, since the second return preventing device is provided on the pachinko ball projecting side with respect to the return preventing device, there is no possibility that the pachinko ball returns near the first return preventing device.

According to the third aspect of the present invention, by providing the pachinko gaming machine with the return preventing device having the above-described structure, the number of pachinko balls to be hit can be easily and accurately managed.

[0015]

An opening 3 is provided, and a pachinko ball intake 14 is provided at the lower end of the slope.

The operating handle 4 is used to drive the hitting portion to drive the pachinko balls taken in from the inlet 14 onto the board 7 through the ball passage 8 so that any of the hit pachinko balls can be used. When the player enters the winning opening 11, a predetermined number of pachinko balls are discharged from the outlet 13 to the pachinko ball insertion tray 3, and further from the pachinko ball payout opening 15 to the receiving tray 5.
To be released respectively.

The alarm lamps 6a and 6b are automatically turned on or flashing when clogging of the board 7 or improper action by a player is detected. In this embodiment, when a trouble such as clogging is detected, 2
The two alarm lamps 6a and 6b are turned on, and when a fraudulent activity is detected, the two alarm lamps 6a and 6b are caused to blink and an alarm sound is generated from the speaker 16.

At the end of the ball passage 8, that is, at a position near the ejection port 17 to the board 7, a return preventing member 18a for preventing the pachinko balls struck on the board 7 from returning to the ball passage 8 side. Is deployed. The return preventing member 18a is formed of a leaf spring having a shape curved in one direction, and the base is fitted and fixed to the inner surface of the guide rail along the direction of the bending of the pachinko ball so that the bending direction is along. The ejection opening 17 is usually set to a closed state.

When the pachinko ball passes through the ball passage 8 and hits the return preventing member 18a, the return preventing member 18a
Is displaced to the curved side by the impact force to open the ejection port 17, and the pachinko ball jumps out of the ejection port 17 and
Guided to the side. On the other hand, for a pachinko ball which is going to return to the ball passage 8 after passing through the ejection port 17, the return preventing member 18a is maintained in a state where the ejection port 17 is closed by its elastic force. Is the return prevention member 1
8a, it falls on the board surface 7.

Further, a second return preventing member 18b is attached to the guide frame 9 on the side where the pachinko balls protrude from the return preventing member 18a, with its displacement direction facing the side where the pachinko balls protrude. This second return preventing member 18b prevents the pachinko balls hit on the board surface 7 from returning to the vicinity of the ejection port 17 and the possibility that the pachinko balls passing through the ejection port 17 enter the ball passage 8 again is as follows. Almost gone.

In this embodiment, each return preventing member 18
Although leaf springs are used for a and 18b, non-elastic metal strips are used in place of the leaf springs, and a rotating mechanism having a spring member is attached to the base thereof, and the metal strips are used as pachinko balls. You may make it displaceably displaceable with respect to a launch side. Further, the mounting positions of the return preventing members 18a and 18b are not limited to the above, and both may be mounted on the guide frame 9 side.

One pachinko ball detection sensor 20 is provided at a position before the first return preventing member 18a. The pachinko ball detection sensor 20 includes a photoelectric switch, a proximity switch, and the like, and outputs a detection signal each time the pachinko ball passes through the installation position.

The detection signal of the pachinko ball detection sensor 20 is input to a hit ball counting counter 21 shown in FIG. 2, and the count value is incremented by "1" each time it is input.

According to such a configuration, the most basic configuration for counting a single signal input may be used as the counter 21 for counting the number of hit balls, and the detection from the two detection sensors may be used. The time required for the counting process is greatly reduced as compared with the method of counting the number of hit balls based on a signal.

If the return preventing members 18a and 18b are made of a material different from that of the pachinko ball, and a dedicated proximity sensor is adopted as the pachinko ball detecting sensor 20, as shown in FIG. The pachinko ball detection sensor 20 can be arranged at the pachinko ball launching side A or at a position B directly below the return preventing member 18a.

Returning to FIG. 1, pachinko ball detecting sensors 22 and 23 are provided at each of the winning port 11 and the out port 12 for detecting the presence of a pachinko ball. , Each pachinko ball detection sensor 22, 2
