Description

[Detailed Description of the Invention] The present invention relates to a dive-type winning detection device for a pachinko machine.

In general, at pachinko parlors, it is important to keep track of how many safe balls are generated in a particular ball winning device during one day of operation, and how many safe balls are generated in all of the ball winning devices in total. It is extremely important to accurately understand the This is because the pachinko machine must be adjusted as necessary based on data such as the number of safe pitches and the number of out pitches. or,
In a pachinko machine, a winning detection device is also required in a specific winning opening that starts a variable display device provided in the gaming section.

Conventionally, winning balls have been detected using a ball guiding path provided on the back of the game board. This ball guiding path is for individually guiding the balls that come out of the ball outlet of a chatter or the like opened on the surface of the game board into the collection gutter on the back of the game board, and a micro switch is installed in the middle of this ball guiding path. was installed to detect winning balls.

However, since this microswitch is a contact device, it is more prone to failure and has problems in terms of reliability and longevity. Another problem was that it required a relatively large installation space. For example, even if an ultra-compact microswitch is used, the actuator must be long enough to operate the contact with the weight of one ball, and space is required for the actuator to extend. do. Therefore, it is necessary to devise a way to attach the micro switch, and when forming a winning device, the entire winning device must be relatively large.

In view of the above, it is an object of the present invention to be able to detect a winning ball that has jumped into a pachinko machine, which has a diving opening located on almost the same level as the game board, and to have a small and compact detection mechanism. To provide a prize detecting device that is simple, has a long life, and is small in size as a whole.

Furthermore, it is an object of the present invention to provide a dive-type winning device that can increase the winning probability and adjust the winning probability in a wide range from high probability to low probability.

Hereinafter, the present invention will be explained based on the illustrated embodiments.

In FIGS. 1 and 2, within the gaming area surrounded by the guide rail 2 of the gaming board 1 of the pachinko machine,
In the center of the gaming area, there is a variable display device 3 including a plurality of variable displays 4, and below it, normally forming a part of the gaming area, there is a specific display mode of the variable display device 3. A variable winning device 5 that converts the winning area into a winning area is arranged. Diagonally above both sides of the variable display device 3, there is a jump-type winning device 6 as a specific winning opening for starting the variable display device 3, and between the variable display device 3 and the variable winning device 5 there is a jump-type winning device 6. A special winning opening 7 is provided in the form. In addition, the symbols 8 and 9 in the figure are general winning openings.

Next, the game played with this pachinko machine will be explained.

When the operation dial 11 provided at the lower part of the front frame 10 is turned slightly, the power of the motor 12 of the batted ball firing device is turned on, and the firing pestle (not shown) is oscillated intermittently.

The ball hit from the firing mallet by this intermittent rocking enters the game area of the game board 1 while being guided by the guide rail 2.

When the hit ball enters the specific winning holes 6 and 7, the variable display device 3 starts operating. The three variable displays 4 constituting the variable display device 3 have the function of sequentially or cyclically changing and displaying a plurality of identification information, such as numbers and symbols. 7-segment numeric display LED in the shape of a ``day''
is used.

When a prize is won in the specific winning slot 6, the numbers displayed on the variable display 4 will change cyclically, and the variable display 3 will change when a certain period of time passes or the stop button 13 is pressed. stops, and the circulation of the display on each variable display 4 also stops.

When the variable display device 3 stops, if the display mode of each stopped variable display device 4 matches a predetermined combination, for example, the variable prize winning device 5 is activated for a length of time according to the weight of the combination. To convert a batted ball into a state that is easy to accept.

At the back of the pachinko machine, the prize ball is placed in the upper tank 1.
5, the tank chute 16, the taxiway 17, and the prize ball discharge device 18 to the ball case.

Winning balls collect in a collection gutter 14 provided on the back of the game board 3
When the winning balls flow down while rolling on the inclined guide shelf forming the lower surface of the ball and enter the winning ball processing device 19, the winning ball processing device 19 takes out the winning balls flowing down on the guide shelf one by one. The crank lever is moved using the weight of the winning ball taken out, and the ball sheath case of the winning ball ejecting device 18, which is interlocked with the crank lever, is tilted. As a result, a predetermined number of prize balls are discharged into the ball supply tray 20 at the front of the Pachinko machine.

In the pachinko machine of the embodiment, in order to improve the probability of winning, a first windmill 21 and a second windmill 22 are provided diagonally below both sides of each dive-type winning device 6, with a first windmill 21 and a second windmill 22 separated laterally. The first windmills 21 are located on both sides of the variable display device 3, and the second windmills 22 are located near the channel deflecting members 23 located at both ends of the game area.

In other words, the first windmill 21 is the specific winning hole 7
and is located above the general winning hole 9 and between the two.

Further, the second windmill 22 is located above the general winning opening 9 and on the side of the game board from the winning opening. In this embodiment, in order to equalize the probability of winning on the left and right sides, two windmill groups consisting of two windmills 21 and 22 are arranged symmetrically with respect to the center line of the game board 1.

Therefore, the first windmill 21 falls into the game area.
The hit ball is guided by the first windmill in the direction of the specific winning hole 7 or in the direction of the general winning hole 9. That is, the player can aim for the specific winning hole 7 or the general winning hole 9. On the other hand, the batted ball that hits the flow path deflection member 23 on the side is guided toward the general winning hole 9 by the second windmill. That is, the player can aim for the general winning hole 9.

In FIGS. 3 and 4, the dive-type winning detection device 6 includes a mounting base 25 that is attached to cover the surface of the game board 1, and a jump-in port 24 (subject) that is formed approximately in the center of the mounting base 25. Well, jumping in 2
A mounting base 25 extends in an edge shape around the game board 4, and the entry hole 24 opens on the same plane as the surface of the game board 1. A mounting base 25 provided around the diving port 24 that attaches to the mouth 2 that follows the diving port 24.
6, a throat 27 for leading out balls following the oral cavity 26, and an optical sensor 2 provided in the throat 27 as a winning ball detector.
8.

An opening 25A for nail insertion is provided on the lower edge side of the mounting base 25, that is, in a portion of the mounting base 25 below the diving opening 24, so as to be close to the diving opening 24, thereby increasing the probability of winning a prize in the diving opening 24. Therefore, the nail 29 that bounces up the ball is connected to the diving hole 24.
The plant can be planted in the opening 25A at the bottom near the bottom.

The opening 25A of the embodiment is opened in the shape of a horizontally long groove, and a plurality of flip-up nails 29 (two in the figure) are driven into the game board 1 through the opening 25A.

By forming this opening 25A, the diving port 2
A flip-up nail 29 can be planted close to the lower part of the ball, and the probability of winning a prize in the diving hole can be greatly increased by the bounce of the falling ball.

The probability of winning at the entrance 24 is determined by the opening 25A.
By adjusting the nails 29 driven into the game board 1 through the
The mounting base 25 is provided with a mounting hole 25B for mounting the mounting base 25 to the game board 1.

The oral cavity 26 in the embodiment shown in FIG.
A cylindrical part 3 that penetrates A and forms a prize winning space.
0, and the throat 27 is provided at the back of the bottom of the oral cavity 26, that is, at the rear side of the game board 1.

However, the oral cavity 26 can also be formed directly by the through hole 1A of the game board 1 without using such a cylindrical part 30.

A tongue 31 is provided on the bottom surface of the oral cavity 26, extending from the diving opening 24 to the throat 27 and slanting backward in order to improve the rolling of the diving ball. This tongue 31 has a wedge-shaped cutout in the center of the tongue from the throat 27 side in order to always guide the ball to the center of the oral cavity 26 and to always pass the ball through a fixed position relative to the optical sensor 28. A V-shaped groove 32 is provided. The depth of the V-shaped cross section of this groove 32 is
The groove becomes deeper downstream of the groove, that is, toward the wider side of the wedge (the throat 27 side).

A rear surface member 33 that constitutes a part of the oral cavity 26 is attached to the rear surface of the cylindrical portion 30.
Two side wall portions 34 and 35 that restrict the width of the throat 27 protrude from the lower portion of the throat 27 to face each other.

Among these two side walls 34 and 35, a light emitting element 28A constituting the optical sensor 28 is inside one side wall 34, and a light emitting element 28A is inside the other side wall 35.
A light receiving element 28B is arranged to receive light from 8A. As can be seen from FIG. 4, the light detection position connecting the light emitting and receiving elements 28A and 28B is slightly shifted from the center of the ball, so that even when winning balls pass successively, each ball can be distinguished and separated. It is designed so that it can be detected.

As can be seen from FIGS. 3 and 5, the upper surfaces 34A, 35A of the two side walls 34, 35 are inclined inwardly, and the tip portions 34B, 35B are , are inclined toward the throat 27 so that the angle formed with the inner edge of the side wall portion is an obtuse angle. The side wall portions 34 and 35 have stepped portions 34C and 35C (third
), both are placed on the tongue 31 and the tongue 3 is placed on the tongue 31.
It is mated with 1. However, the length X of one side wall portion 34 is configured to be longer than the length Y of the other side wall portion 35, and the corner where the inner ridge of one side wall portion 34 and the tip portion 34B contact is wedge-shaped groove 32
The corner where the inner ridge of the other side wall portion 35 and the tip portion 35B contact is located at the downstream end (end on the throat 27 side) of the wedge-shaped groove 32 of the tongue 31.

The shape of the oral cavity 26, that is, the shape of the diving mouth 24 and the cylindrical part 30 which is the winning space following it, is horseshoe-shaped when viewed from the front, and the upper part is made of an arc about twice the diameter of the ball. and a bottom portion consisting of a chord shorter than the diameter of the arc. Therefore, it is possible for two or more balls to jump into the oral cavity 26 from the diving port 24 at the same time. However, as a result of the above configuration,
Even if two or more batted balls fly into the diving port 24 at the same time, these winning batted balls will be lined up one by one in a line and will smoothly reach the optical sensor 2 without clogging.
It passes through the throat 27 where 8 resides.

To be more specific, the inclined surfaces of the tips 34B and 35B of the left and right side walls 34 and 35 function as ball guiding surfaces that guide the winning ball toward the center, and their lengths X and Y are different. Even if two or more balls fly into the ball at the same time, the ball closer to the center will fall a little earlier into the V-shaped groove 32 provided in the center, so the ball will flow downward and form a line.
They flow down the throat 27 one by one. This avoids the occurrence of so-called ball stalling, where the balls mesh with each other and stop flowing down.

As already mentioned, when a winning ball enters the diving hole 24 of the diving type winning device 6 and the winning ball passes through the throat 27 and is detected by the optical sensor 28, the variable display device 3 starts the variable start based on this detection signal. Then, each variable display 4 stops in the order of "left", "middle", "right", and "top".

If another batted ball enters the special winning hole 6 during the period from this one start to the stop of the variable display device 3, the number of balls is memorized up to a maximum of 4, and the number of balls is memorized up to a maximum of 4, and a Another indicator lights up the number corresponding to the number of memory balls to display the number of memory balls.

When the variable display device 3 comes to a variable stop, if the display mode of each variable display device 4 matches a predetermined combination, an electromagnetic solenoid (not shown) is activated for a time corresponding to the weight of the combination. ) is energized, and the opening/closing plate of the variable prize winning device 5 changes from the closed state to the open state. For example, it opens for about 30 seconds when a specific display mode occurs, and for about 0.6 seconds when a small win occurs.
Other combinations will not open. If there is a memory bulb, the variable display device 3 is restarted.

As described above, the dive-type winning detection device of the present invention includes a mounting base that closes a through hole provided in a game board and is fixed to the surface of the game board, and a ball diving opening that is opened in the mounting base. An oral cavity that is continuous with the entry opening and forms a winning space toward the back side of the game board, a throat for ejecting balls that is continuous with the oral cavity and exists on the back side of the game board, and a throat that is opposite to the throat. Since it consists of a side wall section provided with a side wall section and an optical sensor configured by disposing a light emitting element on one side wall section and a light receiving element on the other side wall section of both side walls sections, it is Compared to the case where the structure is configured separately from the conventional ball detection mechanism, the structure can be integrated into a single unit and can be significantly simplified, making it easier to assemble into a pachinko machine and making it easier to handle.

Furthermore, since this optical sensor is integrated into the throat of the winning detection device at the back of the oral cavity, winning balls that fly in with great force lose their momentum, and when they settle down and drift down. As a result, detection can be performed more reliably, and the entire winning detection device can be manufactured in a smaller size and at a lower cost.Compared to the case of using a conventional micro switch, the process of installing the ball detector is not only unnecessary. Functional testing becomes easier and parts management becomes easier.

Furthermore, the present invention provides an opening for nail insertion at the edge of the mounting base below the diving opening so that a flip-up nail can be planted close to the diving opening, thereby increasing the probability of winning a prize. Not only can you do this, but you can also adjust the winning probability in a wide range from high probability to low probability by adjusting the nails of the jump-type winning machine, which has conventionally had a relatively low winning probability.
