Description

[Detailed description of the invention] (Field of industrial application) This invention assembles the upper horizontal member, left vertical member, right vertical member, and lower horizontal member into a rectangular shape, and the lower part of the left vertical member and the right vertical member. A pachinko machine whose machine frame is constructed by fixing a horizontally long reinforcing plate over the lower horizontal member, and whose front frame is attached so that it can be opened and closed, with a game board facing the front opening of the machine frame, especially the spillage of the machine frame. This invention relates to a ball prevention device.

(Prior Art) In a pachinko game parlor, a large number of pachinko machines are installed on an island facility. To explain the circulation path of the pachinko balls, they go from the supply ball transfer device, through the distribution device, and the supply device, and then enter the upper tank of the pachinko machine. Inside each pachinko machine, the upper tank passes through the lead-out gutter to the prize ball ejecting device, and the prize ball ejecting device discharges the pachinko balls one by one through the prize ball ejecting gutter into the supply tray. The feed device sends it to the ejection part of the pachinko machine. The pachinko ball in the firing section is fired into the game area of the game board by the ball firing device, and becomes a safe ball or an out ball. The safe balls or out balls flow down to the lower part of the pachinko machine through the respective discharge troughs and reach the flow down device provided there. Then, the balls flow down from this flow down device to a collection gutter outside the pachinko machine, and are returned to the supply ball transfer device by a lift.

(Problem to be solved by the invention) However, a considerable number of pachinko balls spill from the circulation path, and the spilled balls are scattered around the flow down device 20 as shown in FIG. It will reach you. For this reason, it was necessary to manually return the spilled ball to the circulation path.

A pachinko game parlor usually has around 300 pachinko machines. If you look at the lower part of the pachinko machine, you will see about 100 pachinko balls per machine. This shows that when looking at the game parlor as a whole, there are approximately 30,000 pachinko balls in play. As a result, inconveniences occur, such as not enough supply balls being distributed from the supply transfer device to each pachinko ball, and the pachinko balls that have not arrived oxidized due to not being used for a long time. was. If the oxidized pachinko balls return to the pachinko ball circulation path, they may have a negative effect on other unoxidized pachinko balls or pollute the pachinko ball circulation path. Secondary inconveniences such as the ball not stopping also result.

The present invention has been made in view of such problems, and an object thereof is to provide a spill ball prevention device that prevents spill balls from reaching the lower part of the pachinko machine frame 3.

(Means for Solving the Problems) The present invention is a ball spill prevention device that is attached to the pachinko machine mentioned at the beginning, and includes a falling ball guide surface that is inclined toward the collection gutter, and a width or width of the falling ball. It is characterized by having an inner positioning member for adjusting the difference in the mounting position, etc., an outer positioning member for adjusting the difference in the width of the machine frame, and a fastening part for attaching the ball spill prevention device to the machine frame. It is.

(Function) Spilled balls always flow down the flow guide surface, fall into the collection gutter, and return to the ball circulation path. Therefore, the pachinko balls are used effectively and do not reach the lower part of the pachinko machine, resulting in a shortage of balls or rusting. Furthermore, the troublesome work of manually returning balls that have reached the lower part of the pachinko machine to the collection gutter can be omitted.

In addition, it has an inner positioning member that adjusts the width of the downstream device or the mounting position, and an outer positioning member that adjusts the width of the machine frame, so it can be adapted to pachinko machines and island equipment from different manufacturers. I can do it.

(Example) Hereinafter, the present invention will be explained based on an example of a pachinko machine shown in the drawings.

In FIG. 1, a large number of pachinko machines 2 are placed on a pachinko machine mounting table 1, which is part of an island facility, forming a row of pachinko machines. 3 is a machine frame of the pachinko machine 2, and this machine frame 3 includes an upper horizontal member 3A (Fig. 4), a left vertical member 3B, a right vertical member 3C, and a lower horizontal member 3D.
are assembled into a rectangular shape, and the left vertical member 3B and the right vertical member 3
It is constructed by fixing a laterally elongated reinforcing plate 4 across the lower part of C and the lower horizontal member 3D. As shown in FIG. 4, a picture frame-shaped front frame 5 is attached to the front opening of the machine frame 3 configured in this manner so as to be openable and closable, and a game board 6 is faced from the back side through the opening window of this front frame 5. be.

To explain the circulation path of pachinko balls based on FIG. 4, the balls enter the upper tank 10 of the pachinko machine from the supply ball transfer device 7, which constitutes a part of the island equipment, through the distribution device 8 and the supply device 9. Inside the pachinko machine, the upper tank 10 passes through the lead-out gutter 11 to a prize ball discharge device (not shown), and is discharged by the prize ball discharge device to the supply tray 13 via the prize ball discharge gutter 12. When it is full, it is discharged to the lower tray 14. The pachinko balls in the supply tray 13 are sent one by one to a firing section (not shown) of the pachinko machine by a ball feeding device (not shown). The pachinko balls in the firing section are fired into the game area of the game board 6 by a ball firing device (not shown), and either enter the winning hole 15 and become a safe ball, or fall into the out hole 16 and become an out ball.
These safe balls or out balls pass through each discharge gutter 17 on the back of the game board, are collected at the lower part of the collection gutter 18, flow down from the discharge gutter 19 to the lower part of the pachinko machine, and reach the flow down device 20 provided there. . and,
The water flows down from this flow down device 20 to the collection gutter 1A located on the rear side of the pachinko machine mounting table.

The falling device 20 collects the balls that have fallen into the sloping bottom 2.
A ball receiving case 21 configured to collect at a discharge port 22 provided downstream of the ball receiving case 1A, and a ball counting device 24 that counts the balls flowing down from the discharge port 22 of the ball receiving case through a discharge gutter 23. configured. The width h of the ball holder case 21 varies somewhat depending on the manufacturer, and the width H of the machine frame 3 of the pachinko machine also varies depending on the manufacturer or model. For this reason, the ball holder case 21
When the Pachinko machine 2 is installed on the Pachinko machine table 1, it is fixed to the Pachinko machine table 1 by a metal fitting 25, and its discharge port 22 is aligned with the discharge gutter 23 of the ball counting device 24.

In FIGS. 1 and 2, numeral 30 indicates a ball spill prevention device of the present invention.

The spilled ball prevention device 30 is mainly composed of a downward guide member 31 arranged to surround the ball receiving case 21 except for the back surface thereof. In this embodiment, the downward guide member 31 has a plate shape as a whole. It has a notch 32 into which a part of the ball receiving case 21 can fit. The upper surfaces of both side portions of the spill ball prevention device 30 with respect to the ball receiving case 21, that is, both side portions 33 of the notch 32 of the downward guide member 31, are formed as downward guide surfaces 33A having an inclination toward the collection gutter 1A. Also, a bridge portion 34 connecting the two downstream guide surfaces 33A, 33A on the front side of the ball receiving case 21
is formed into a mountain shape, and its sloping upper surface functions as a downstream guide surface 34A in the direction of the downstream guide surfaces 33A on both sides.

On the lower surface of both side portions 33 of the downstream guide member 31,
Even if the width of the flow device 20 or the mounting position is different, the flow guide surface 33A can be fully extended on both sides of the ball receiving case 21.
A plate-shaped inner positioning member 35 is slidably housed in the machine frame 3 in the lateral direction in order to be able to adjust it so as to enlarge it. That is, slide grooves 36 and 37 formed by bending the front and rear edges of the downstream guide member 31 toward the rear side are provided in both side portions 33 of the downstream guide member 31, and the inner positioning member is inserted into the slide grooves 36 and 37. Both edges of 35 are stored. Of these slide grooves 36 and 37, the slide groove 36 on the front edge side in particular is formed by bending from the lower part of the bridging portion 34 toward the outside of the machine frame in order to prevent the inner positioning member 35 from being pulled out too much and detached. It is designed to function as a stopper. Further, the inner positioning member 35 is provided with an operating portion 35A bent upward into an L-shape in order to facilitate insertion and removal operations.

On the lower surface of one of the both side parts 33 (the right side in FIG. 2) of the downstream guide member 31, there is a width H of the machine frame 3.
A plate-shaped outer positioning member 38 is slidably housed in the lateral direction of the machine frame 3 in order to be adjustable so that the downstream guide surface 33A can be expanded to its full width even if the width is different. The slide groove for the outer positioning member 38 is formed by bending the front and rear edges of both side portions 33 toward the back side so as to face each other.

Mounting ears (fastening parts) 31A are provided on the left and front edges of both side parts 33 of the downstream guide member 31, and mounting ears (fastening parts) 31A are provided on the right end of the outer positioning member 38. The ear portion 38A of the outer positioning member 38 also functions as an operation portion that facilitates the insertion and removal operation.

The downstream guide member 31 having the above configuration is attached to the left and right vertical members 3B, 3C and the reinforcing plate 4 of the machine frame 3, using the mounting ears 31A, 38A, just above the lower horizontal member 3D of the machine frame 3. It is screwed together to form a ball spill prevention device 30.

Adjusting the width of the downstream guide member 31 to the width H of the machine frame 3 can be easily done by pulling out the outer positioning member 38. In addition, when installing the downstream guide member 31, the downstream guide surface 33
It is necessary to incline the upper surface so that the trailing edge is at a lower position. For example, the mounting ear 31A may be made to protrude in advance at a predetermined inclination angle to the downstream guide surface 33, or the slide groove 36 By appropriately determining the height of the groove forming portion 36A constituting the machine frame 3, it is possible to uniquely determine the angle of inclination of the downstream guide surface 33 with respect to the machine frame 3, thereby simplifying the installation work.

To adjust the installation position of the flow device 20 or the difference in its width h, pull out the inner positioning member 35 using the operation part 35A, bring it into contact with the side surface of the ball receiving case 21, and tighten the bolt 39 and nut 40 as shown in FIG. 3, for example.
It may be fixed immovably using a suitable fixing means as shown in .

The downstream guide member 31 thus attached to the pachinko machine 2 has a depth slightly larger than the machine frame 3,
While covering the area of the lower cross member 3D of the machine frame 3, the trailing edge of the downstream guide member 31 protrudes outside the area of the lower cross member 3D of the machine frame 3. Further, the downstream guide surface 33A is always expanded to the width H of the machine frame 3 and the entire circumference of the downstream device 20 by the inner positioning member 35 and the outer positioning member 38. Therefore, balls spilled from the circulation path of pachinko balls are picked up by this enlarged downstream guide surface and sent along this to the collection gutter 1.
It flows down to A and does not reach the lower part of the pachinko machine 2. Also, if the reinforcing member 4 and the flow down device 20
Even if the ball falls between the collection gutter 1 and
It is collected by A.

In order to widen the applicable range of the ball spill prevention device 30, the width of the notch 32 should be adjusted to cover the range where the mounting position of the ball receiving case 21, which has the largest width, is changed, and the width of the falling ball guide member should be The width of 31 is the machine frame 3 of a pachinko machine with the smallest width H.
It is better to set it so that it can be entered inside. When determined in this way, the amount by which the inner positioning member 35 is pulled out and the amount by which the outer positioning member 38 is pulled out are also determined naturally.

FIG. 3 shows a modification of the ball spill prevention device 30. The first difference from FIG. 2 is that the downstream guide member 3
A slit 41 through which the dust passes is provided in the downstream guide surface 33A of the both side portions 33 of 1, and an opening 42 through which the dust passes through the slit 41 is provided in the inner positioning member 38. I am trying to receive it at The slit 41 is opened to a width that allows dust to pass through but does not allow pachinko balls to pass through, and the direction of the slit is made to match the downward direction of the ball flow so as not to impede the rolling of the balls. The opening 42 has a size that covers the width of the slit 41 in the downward direction of the ball flow. Further, the tray 43 is connected to the downstream guide member 31.
It has an area corresponding to one of the downstream guide surfaces 33A, and is placed on the lower cross member 3D of the machine frame 3, as illustrated on the right side of FIG. It is preferable that the tray 43 is provided with a handle 44 to facilitate its removal, thereby facilitating the work during the dust removal process.

The second difference from FIG. 3 is the means for fixing the inner positioning member 35. That is, the slit 41 is
The downstream guide surface 33A is divided into two stages, an upper row and a lower row, and the opening 42 of the inner positioning member 35 is also formed into an upper and a lower row, leaving an intermediate section 42A. A large number of hooking recesses 45 are formed on both sides of the slit 42A in the row direction of the slits 41. The recesses 45 on both sides of the intermediate portion 42A are
It is equal to or slightly smaller than the interval between the upper and lower rows of slits 41. 46 is a flexible clip bent to a width corresponding to this interval, and its tip 46
While expanding the space between A and 46A, insert one end into the slit 41 in the upper row and the other end into the slit 41 in the lower row, and insert the tip portions 46A and 46A into one of the recesses 45 and 45.
The inner positioning member 35 is fixed at a desired drawn-out position using the elastic return force of the clip 46.

The fixing means using the clip 46 is extremely easy to operate because it is fixed on the upper surface of the downstream guide member 31 instead of the lower surface like the bolts 39 and nuts 40, and the pachinko machine 2 can be attached to a pachinko machine on an island. To facilitate fixation according to the size and position of a falling device 20 when installing it on a mounting table 1. In addition, the downward guide surface 33A of the clip 46
The back portion remaining on the top coincides with the downward guide direction of the ball, so it does not hinder the downward flow of the ball.

In the above embodiment, the inner positioning member 3 is used to adjust the width of the flow down device 20, the mounting position, etc.
5 are provided on both sides of the flow down device 20, but they can also be provided on one side of the flow down device 20. This is because even when the inner positioning member 35 is provided only on one side, spilled balls can be effectively picked up for several models of the same manufacturer. In addition, in the example,
Although the outer positioning member 38 for adjusting the difference in the width H of the machine frame 3 is provided only on one side, it may be provided on both sides. This is because the amount by which the outer positioning member 38 is pulled out is shared between the outer positioning members 38 on both sides, which has the advantage of reducing restrictions on the amount by which the inner positioning member 35 is pulled out.

Furthermore, the downstream guide surface 33A that is inclined toward the collection gutter 1A does not necessarily need to be provided on both sides of the downstream device 20, and may be provided only on one side. This is because at least half of the spilled balls, which were previously wasted, can be recovered and used.

In short, as a spill ball prevention device, a falling guide surface 33A having an inclination toward the collection gutter 1A,
An inner positioning member 35 for adjusting the width or the mounting position of the falling ball 20, an outer positioning member 38 for adjusting the width H of the machine frame 3, and a stop for attaching the ball spill prevention device 30 to the machine frame. It is sufficient if it has a wearing part.

(Effects of the Invention) As described above, according to the spilled ball prevention device of the present invention, spilled balls always flow down the flow guide surface, fall into the collection gutter, and are returned to the ball circulation path. Therefore, since the pachinko balls owned by the pachinko parlor are effectively used, there is no shortage of balls in the pachinko ball circulation route. In addition, since the balls that reach the lower part of the pachinko machine do not rust as in the past, the inside of the pachinko island can be kept clean.
Of course, the troublesome work of manually returning balls that have reached the lower part of the pachinko machine to the collection gutter can also be omitted.

In addition, it has an inner positioning member that adjusts the width of the downstream device or the mounting position, and an outer positioning member that adjusts the width of the machine frame, so it can be adapted to pachinko machines and island equipment from different manufacturers. I can do it.
