Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a passing ball detection device disposed on the back side of a game board of a pachinko machine.

(Prior Art) Generally, as shown in FIG. 8, a pachinko machine is equipped with a passing ball detector including a head with a ball passage section 11, a detector main body 12 following the head, and a detector main body 12 that protrudes from a part of its upper surface. A commercially available micro switch 10 is used, which has a flange 13 and a vertical groove-like recess 14 provided adjacent to the flange 13 on its side surface.

Conventionally, such a micro switch 10 has been disposed between the back surface of the game board 1 of a pachinko machine and the collecting gutter 2, and a passing ball detection device has been configured as shown in FIGS. 9 and 10, for example. Another type of game is known in which the micro switch 10 is arranged horizontally parallel to the back surface of the game board 1.

To be more specific, A and B in Fig. 9 have a claw 4A at the tip.
A holder 3 having two opposing walls 4, 4 with markings is attached to the back side of the game board 1, and the detector main body 12 of the micro switch 10 is placed between the walls 4, 4 of the holder 3, with its side surface The holder 3 is stored parallel to the back surface of the game board 1, and the claws 4A, 4A are inserted into the vertical groove-shaped recesses 14 on the top surface of the micro switch 10 to hold it.The mounting position of the holder 3 is as follows.
A ball passage part 11 of the micro switch 10 is determined to be located at the lower end of a winning ball guiding path 6 formed by a winning ball guiding path member 5 on the back surface of the game board 1 and a collection gutter 2.

A and B in FIG. 10 show that one side surface 12B (see FIG. 3) of the detector main body 12 of the micro switch 10 is brought into contact with the mounting board part 7A of the winning ball guide gutter 7, and the The detector main body 12 is sandwiched between the band body 8 from the other side surface 12A (see Fig. 1), and the outward flange 8A of the band body 8 is fixed with screws 9 to the fastening part 7B protruding from the mounting board part 7A. The ball passage section 11 of the micro switch 10 is connected to the winning ball guiding gutter 7.
In the middle of the winning ball guiding path 6 in the winning ball guiding path 7.
It is positioned so that it is continuous with.

(Problems to be Solved by the Invention) A problem common to the above two methods of configuring the passing ball detection device is that the micro switch 10 is placed sideways with respect to the game board 1, that is, the micro switch 10 is completely aligned with the game board 1. It is disposed in the gap between the collecting gutter 2 and the collecting gutter 2.

Therefore, if the micro switch 10 breaks down during operation of a game parlor, ie, a pachinko parlor, and it becomes necessary to replace the switch, the switch can only be replaced after the collecting gutter 2 has been removed.

On the entire back side of the game board 1 currently in use,
A large number of wiring cords related to such multiple microswitches and other electrical components are crowded together. For this reason, replacing the microswitch is troublesome and time-consuming, and requires a considerable amount of work time. Furthermore, when replacing the micro switch, for example in the configuration shown in FIG. 9, the two walls 4, 4 of the holder 3 are expanded outward, and the claw
A, 4A is the vertical groove-shaped recess 1 of the micro switch 10.
4, and at this time, walls 4, 4
I often spread it too much and damaged it.

In addition, in the configuration shown in FIG. 10, the outward flanges 8A, 8A of the band member 8 are screwed to the mounting board portion 7A at two locations to secure the micro switch 10. Therefore, it took time to attach and detach screws, and the work efficiency was relatively low.

Next, the micro switch 10 is arranged horizontally with respect to the game board 1 surface, and the micro switch 10 is placed between the game board 1 and the collecting gutter 2. This means that the lead wire 15 must be passed through the inside of the collecting gutter 2, that is, the gap between the game board 1 and the collecting gutter 2, that is, the space in which the balls flow. Such wiring processing allows the winning balls flowing down inside the collection gutter 2 to
The lead wire 15 obstructs the flow and causes ball clogging.

Furthermore, arranging the micro switch 10 horizontally with respect to the game board 1 has the problem of taking up a relatively large space. Usually, game board 1
Today, the structure of the back side of the game board 1 has become extremely complicated because many parts such as a winning ball guiding path member and an electric drive source are attached to the back side of the game board 1.
Under such circumstances, the fact that the micro switch 10 is arranged horizontally with respect to the game board 1 and occupies a relatively large space means that it occupies a large space in the limited space on the back side of the game board 1. This significantly restricts the installation location of other parts or makes installation impossible.

The present invention was made in view of these problems, and eliminates the unreasonableness of arranging the passing ball detector sideways with respect to the game board 1, and also makes it easy to attach and detach and replace the passing ball detector. The purpose of this invention is to provide a passing ball detection device.

(Means for Solving the Problems) The passing ball detection device for a pachinko machine of the present invention includes a head with a ball passage section 11, and a detector main body 1 following the head.
2. Passing ball detector 10 having a through hole 16 extending from one side 12A to the other side 12B of the detector body 12; Winning balls facing each other at an interval that allows the head of the passing ball detector 10 to be inserted. A winning ball guiding gutter 20 having guiding path forming side walls 21 and 22 and a fastening part 26 provided on the outside of at least one of the side walls.
and a winning ball guide gutter 20 arranged on the back side of the game board 1 so that both side walls stand up against the back surface of the game board 1; attached to the fixing part 26 of the winning ball guide gutter 20. The detector fixing member 30 includes an opposing surface 31 that can come into contact with the side surface of the detector main body 12 of the passing ball detector 10 whose head is inserted between the side walls of the winning ball guiding gutter 20, and the opposing surface 31. The detector fixing member 30 has projections 33 and 34 that can be inserted into the through hole 16 of the detector main body 12 provided in the detector body 12.

(Function) In the passing ball detection device for a pachinko machine of the present invention, the existing through hole 16 or 17 that passes from one side of the detector body 12 of the passing ball detector 10 to the other side.
The detector fixing member 30 is inserted into the through hole 16 or 17 of the passing ball detector by using the detector fixing member 30 having a projection that can be inserted into the through hole 16 or 17.
After inserting the projections 33 and 34, the detector fixing member 30 is attached to a fastening portion 26 provided on the outside of at least one side wall of the winning ball guiding gutter 20 forming the winning ball guiding path 25. At this time, the head 11 of the passing ball detector 10 is inserted between the winning ball guiding path forming side walls of the winning ball guiding gutter 20. Winning ball guiding gutter 2
0 is placed on the back side of the game board 1 so that the side wall forming the winning ball guiding path 25 stands up against the back side of the game board 1, so the passing ball detector 10 It is attached to the winning ball guiding gutter 20 so that the direction stands up with respect to the back surface of the game board 1, that is, in a "vertical" state.

If you want to remove the passing ball detector 10, remove the detector fixing member 30 from the attachment part 26 of the winning ball guide gutter 20, and the projections 33, 34 will be attached to the through hole 16 or 17.
The passing ball detector 10 can be removed as a whole while it remains inserted.

Since the passing ball detector 10 is arranged vertically with respect to the game board 1, the protrusions 33 and 34 of the detector fixing member 12 are inserted into the through hole 16 or 17 of the detector main body 12 in the collecting gutter 2. By providing a relatively small opening that allows the integrated assembly to pass through, it is extremely easy to attach and detach the passing ball detector 10 from outside the collecting gutter 2 without removing the collecting gutter 2. obtain.

(Example) Hereinafter, the present invention will be explained based on the illustrated example.

As shown in FIG. 1, the passing ball detection device of the present invention uses a micro switch 10 as a passing ball detector.
, a winning ball guiding gutter 20 and a detector fixing member 30 made of synthetic resin. FIGS. 2 and 3 show a state in which these three members are integrally assembled.

In Figures 1 to 3, micro switch 1
0 is a head with a ball passage section 11, a detector body 12 following this, a ball passage section 11, and a detector body 12.

A connecting terminal 18 is provided at the rear end of the micro switch 10, and a lead wire 1 is connected to the terminal 18.
5 is drawn. In addition, inside the ball passage section 11,
The actuator 19 (FIG. 3) of the microswitch 10 is exposed.

The winning ball guiding gutter 20 has two side walls 21 and 22 for forming a winning ball guiding path that face each other at an interval that allows insertion of the ball passage section 11 of the passing ball detector 10, and a U-shape between the two side walls 21 and 22. It has a rear wall 23 which is connected to the rear wall 23 and an outward mounting flange 24 extending from the edge of the rear wall 23.

The side walls 21, 22 and the rear wall 23 form a ball guiding path 25.
is formed. The depth of the winning ball guiding path 25, that is, the height of the side walls 21, 22 from the rear wall 23, is the same as the length of the ball passage section 11 when viewed in the longitudinal direction of the passing ball detector 10.

A columnar fastening part 26 is integrally provided on the outside of one side wall 21 of the winning ball guiding gutter 20, and the top surface of this fastening part 26 is connected to the side wall 2 in this embodiment.
It is on the same level as the top surfaces of Nos. 1 and 22.

In order to form an insertion receptacle 27 for inserting and holding the ball passage portion 11 of the micro switch 10 at right angles on the inner surfaces of the side walls 21 and 22, the side wall 21 has protrusions 27A and 27B at two places on the upper and lower sides. Regarding the side wall 22, 27B is provided.

Furthermore, the inner surfaces of the side walls 21 and 22 are provided with markings that act on the balls falling in the gutter 20 to reduce their velocity and change the outflow direction of the balls flowing out of the gutter 20, as shown by broken lines in FIG. In order to change the structure and increase the strength of the side wall of the gutter 20, an appropriate number of working protrusions 28 are arranged in a staggered manner.

As shown in FIG. 1, a rectifying section 29 is formed in the upper part of the winning ball guiding gutter 20. In detail,
In the rectifying section 29, the distance between the side walls 21 and 22 is widened, and the side wall 22 has a rectifying slope 22A with a gentle slope. The batted balls are arranged in a line so that they can flow smoothly into the gutter 20.

Further, as shown in FIG. 4, the upper edge 23A of the rear wall 23 of the rectifier 29 is inclined so that the ball from the winning hole 42A can quickly flow into the gutter 20.

The winning ball guiding gutter 20 having the above configuration has its side wall 2
1 and 22 are arranged on the back side of the game board 1 so that they stand up against the back side of the game board 1. In this embodiment, as shown in FIG. 3, an outward mounting flange 24 is directly mounted on the back surface of the game board 1 through its mounting hole 24A. As a result, when the ball passage portion (head) 11 of the passing ball detector 10 is inserted into the insertion receptacle 27, the passing ball detector 10
is held in a "vertical" state with its longitudinal direction standing up against the back surface of the game board 1. However, with this alone, the passing ball detector 10 will still not fit into the insertion receptacle 27.
It is in a state where it can fall out.

The detector fixing member 30 has an opposing surface 31 that can come into contact with the side surface 12A or 12B of the detector main body 12 of the passing ball detector 10, and a fixing part 26 of the winning ball guiding gutter 20.
It has a mounting ear 32 for. In this embodiment, the opposing surface 31 is made of a plate bent into an approximately L-shape as a whole, and the outer surface of this plate, that is, the side where the mounting tab 32 is not present, is the opposing surface 31.

The opposing surface 31 has a through hole 1 of the detector main body 12.
6, 17 are provided with insertable protrusions 33, 34 in the form of pins, and the mounting ears 32 are provided with elongated holes 36 through which fixing screws 35 are passed.

The passing ball detector 10 and the detector fixing member 30 are integrated by inserting the protrusions 33 and 34 into the through holes 16 and 17 so that the opposing surface 31 faces the side surface of the detector body 12. In this embodiment, a single engagement piece 37 is provided protruding from the L-shaped bent edge, and when the passing ball detector 10 and the detector fixing member 30 are integrated, this engagement piece 37 is configured to fit into the vertical groove-shaped recess 14 of the passing ball detector 10.

When integrated in this way, the ball passage portion (head) 11 of the passing ball detector 10 projects beyond the mounting ears 32, so the ball projecting from the detector fixing member 30 remains integrated. Passage part (head) 11
can be inserted into the insertion receptacle 27 of the winning ball guiding gutter 20.

After insertion, as shown in Figure 2, attach the mounting ears 32.
By aligning the elongated hole 36 with the fastening part 26 of the winning ball guiding gutter 20 and attaching the mounting lug 32 to the fastening part 26 with the screw 35 as shown in FIG.
Thereafter, it is fixed to the winning ball guiding gutter 20 so that it cannot fall off in the vertical and longitudinal directions.

As described above, in the passing ball detection device for a pachinko machine of the present invention, the protrusion of the fixing member 30 is inserted into the existing through hole 16 or 17 that passes from one side of the detector body 12 of the passing ball detector 10 to the other side. 33 or 3
4 and are assembled integrally, the ball passage section 11 of the passing ball detector 10 is inserted into the insertion receptacle 27 of the winning ball guiding gutter 20, and the detector fixing member 30 is inserted into the winning ball guiding gutter 20. It is attached to a fastening part 26 on the outside of at least one side wall of. Thereby, the passing ball detector 10 can be easily fixed vertically and longitudinally so that it cannot fall off, or can be easily removed.

In the above embodiment, the number of protrusions 33 and 34 on the detector fixing member 30 is determined according to the number of through holes 16 and 17 provided in the detector main body 12.
If there is at least one engagement between the through holes 16 and 17 and the projections 33 and 34, the passing ball detector 10
can be fixed in the vertical and longitudinal directions so that they cannot fall off. Therefore, it is necessary to provide the insertion receptacle 27 in the winning ball guiding gutter 20 in advance, and to attach the engaging piece 3 to the detector fixing member 30.
7 is not necessarily required. However, if you want to actively provide the protrusions 27A and 27B to accurately regulate the insertion position of the head 11 of the passing ball detector 10, the ball passage section 11 of the passing ball detector 10 should be connected to the winning ball guide channel. There is an advantage that the ball can be accurately detected by accurately matching the inside of the ball. The detector fixing member 30 is located on the side surface 12A side of the detector main body 12,
It may be provided on either side of 12B, or may be provided on both sides.

Next, the winning ball guiding gutter 20 has its side walls 21 and 2.
There is no restriction on the overall shape or arrangement except that the distance between the two must not be smaller than the distance between the heads 11 of the passing ball detector 10. For example, the top surface of the fastening part 26 does not necessarily need to be at the same level as the side walls 21 and 22, but may be formed lower or higher than the height of the side walls 21 and 22, and the height of the detector fixing member 30 may be adjusted accordingly. The position of the mounting ear 32 can be shifted. In addition, a rectifying part 29 may be provided at the top, or action protrusions 2 may be provided on the inner surface of the side wall.
It is also up to you whether or not to provide 8.

(Application Example) FIGS. 5 to 7 show an example of application of the passing ball detection device shown in FIG. 1 to an actual pachinko machine.

In the pachinko machine shown in FIGS. 5 and 6, a variable display device 40 including a plurality of variable display devices is provided at the center of a game area surrounded by guide rails of a game board 1. Below that, a variable winning device 41 is arranged which normally forms part of the gaming area, but which converts into a winning area when a specific situation occurs. Each variable display device of the variable display device 40 is
For example, it is a 7-segment numerical display LED in the shape of a "day" that sequentially changes and displays a plurality of identification information.

Diagonally above the variable display device 40, there is a jump-type prize opening 42A that starts the variable display device 40.
Further, between the variable display device 40 and the variable winning device 41, there is provided a specific winning device 43 having a winning opening 43A in a different form.

Above the variable display device 40, “Heaven” and “Left of Heaven” are displayed.
Three prize openings 44A, 44B, 44 on the “right side of the sky”
A general winning device 44 having a symbol C is provided, and a winning opening 4 is provided on the diagonally downward outer side of each specific winning device 42.
The general prize winning tools 45 having 5A are arranged in the form of "left sleeve tip" and "right sleeve tip". An out hole 46 is provided at the bottom of the game area.

In FIG. 6 and FIG. 7, regarding the two specific winning devices 42 mentioned above, the above-mentioned winning devices are placed on the back side of the game board 1 so as to individually guide the winning balls from the winning holes 42A. A ball guide gutter 20 is provided.

As described above, the head 11 of the passing ball detector 10 integrated with the detector fixing member 30 is inserted into the insertion receptacle 27 of each winning ball guide gutter 20, and the passing ball detection Detector body 1 of device 10
2 is fixed to the fastening part 26 of the winning ball guiding gutter 20 via the detector fixing member 30. Therefore, as shown in FIG. 7, each passing ball detector 10 stands up in a T-shape on the back surface of the game board 1 so that it cannot be easily removed due to vibrations or the like.

This T-shaped passing ball detector 10
protrudes rearward through a collection gutter 2 arranged on the back side of the game board 1. The gathering gutter 2 is the game board 1
The prize opening 41A of the variable prize winning device 41 which is open on the back side of the prize winning device 41A, and the prize winning hole 42A, 43A of the specific winning prize device
Or, the winning slots 44A, 44B, 44C for general winning gear.

Through this opening 47, a portion of the detector body 12 of the passing ball detector 10 is inserted into the collection gutter 2 together with the detector fixing member 30 integrated therewith.
appearing outside.

In this embodiment, the opening 47 is a rectangular opening that is larger than the arc-shaped mounting ear 32 of the detector fixing member 30. However, the opening 47 may have any size or shape that allows the combination of the passing ball detector 10 and the detector fixing member 30 that are integrated with each other to be inserted therethrough, and may be an arc-shaped opening 47 according to the shape and size of the mounting ear 32. It can also be formed as follows.

On the inner surface of the collection gutter 2, there is a winning ball guiding path for guiding winning balls from the winning ports 44A, 44B, 44C of the general winning device 44 to distinguish them from winning balls coming from the winning ports 42A, 43A of the specific winning device. A member 48 is erected. The existence of this winning ball guide path member 48 prevents the inconvenience of winning balls entering from the winning opening of the general winning tool 44 flowing into the winning ball guiding gutter 20 or hitting the passing ball detector 10 and giving an impact. are doing.

When a winning ball is won in the above-mentioned specific winning device 42, the winning ball rolls down from the winning opening 42A into the rectifying part 29 of the winning ball guiding gutter 20, and the passing ball detector 10 provided in the winning ball guiding gutter 20 is activated. Back, gathering gutter 2

Winning balls from the winning holes 44A, 44B, and 44C on the "right side of the sky" are guided downward along the winning ball guiding path member 48 and released into the collecting gutter 2. The winning balls released into the collecting gutter 2 are the general winning balls 45.
Along with the balls hit from the winning openings 45A ("left sleeve tip" and "right sleeve tip"), the balls pass through the collecting gutter 2 and are collected by a lower member (not shown).
Incidentally, the specific winning device 43 can also be provided with a passing ball detection device including the passing ball detector 10, the winning ball guiding gutter 20, and the detector fixing member 30, similar to the specific winning device 42.

When the passing ball detector 10 belonging to the specific winning opening 42A or the ball detector belonging to the specific winning opening 43A is activated, the variable display device 40 starts to operate, and the numbers that are the display contents of the variable display change cyclically. .
After a certain period of time passes or by pressing the stop button 53, each variable display changes to "left", "middle", or "right".
Stop in “top” order. If more batted balls win in the specific winning holes 42A, 43A during the period from this one start to the stop of the variable display device 40, the number thereof is stored up to 4. When it stops, if
If the display content of each variable display matches a predetermined combination, the opening/closing plate of the variable prize winning device 41 opens for a length of time corresponding to the weight of the combination. For example, it opens for about 30 seconds when a specific aspect occurs, and for about 0.6 seconds when a small win occurs. Then, if there is a memory bulb, the variable display device 40 is activated again.

(Effect of the invention) As described above, in the passing ball detection device for a pachinko machine of the invention, the existing through hole passing through from one side of the detector body of the passing ball detector to the other side, and this through hole The passing ball detector can be attached to the winning ball guiding gutter in a "vertical" state standing up against the back surface of the game board by using a detector fixing member having a protrusion that can be inserted into the winning ball guiding gutter. That is, after inserting the protrusion of the detector fixing member into the through hole of the passing ball detector,
By attaching the detector fixing member to the fixing portion provided on the outer side of at least one of the side walls of the winning ball guide gutter, the passing ball detector can be fixed so as not to fall off in the vertical and longitudinal directions.

Therefore, compared to the conventional passing ball detector in which the passing ball detector is arranged horizontally on the back surface of the game board, the space occupied by the passing ball detector on the back surface of the game board can be reduced to a fraction of that. Moreover, this increases the degree of freedom in attaching other parts, and the limited space on the back of the game board can be used effectively. If you want to remove the passing ball detector, simply remove the detector fixing member from the attachment part of the winning ball guide gutter, and the passing ball detector can be pulled out backwards together with the detector fixing member. . Therefore, also
Even if there is a collecting gutter that covers the winning ball guide gutter, simply provide the collecting gutter with an opening small enough to allow the combination of the passing ball detector and detector fixing member to pass through in the vertical direction. By simply removing the collecting gutter, the passing ball detector can be directly attached and removed from the outside of the collecting gutter, making replacement extremely easy.

Furthermore, the connection terminal and its lead wire at the rear end of the passing ball detector are not placed inside the collection gutter, unlike the conventional case where the passing ball detector is arranged horizontally with respect to the game board, but are placed outside the collecting gutter. Since the wires can be positioned and processed, the replacement work becomes extremely easy. Moreover, since winning balls flowing down inside the collecting gutter will not be attracted to the lead wire and cause clogging of balls, there is no need to take any preventive measures.
