Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a coin rolling selector for sorting inserted coins while rolling them.
In particular, the present invention relates to a coin rolling selector used in a game machine such as a pachinko slot or a so-called pachislot.
Of course, the term “coin” in the present specification includes a small disk-shaped coin as a currency.
Furthermore, the term “coin” in the present specification includes a disk-shaped medal and token used for games and the like.
[0002]
[Prior art]
Various coin rolling selectors used in medal game machines and pachislot machines have been developed.
For example, the selector is disclosed in Japanese Utility Model Laid-Open No. 6-25963 (actual application No. 4-23240) by the present applicant.
FIG. 7 schematically shows a coin rolling type selector disclosed in Japanese Utility Model Laid-Open No. 6-25963.
It should be noted here that actual application No. 4-23240 constitutes US Pat. No. 5,293,981.
[0003]
FIG. 7A is a schematic slope view of the entire selector as viewed from the upper left. FIG. 7B is a schematic cross-sectional view of the selector as viewed from the side.
The selector shown in FIG. 7A has a large main frame 4 that is long on the side.
Attachment pieces 19 and 18 are formed at the respective ends of the main body frame 4.
The main body frame 4 is tilted and fixed in the pachislot machine by these mounting pieces 19 and 18.
That is, the main body frame 4 is fixed with the length direction being inclined with respect to the horizontal plane and the width direction being also inclined (see FIG. 7B).
[0004]
A slightly large rectangular window 9 is opened substantially under the center of the main body frame 4.
A rectangular coin guide 10 having a long rectangular shape is fixed to the upper edge of the window 9 (see FIG. 7B).
A pivot 8 is attached to the main body frame 4 above the coin guide 10. A small bent plate arm 11 is rotatably attached to the pivot 8.
That is, the lower half of the plate arm 11 can enter and exit the window 9.
The pistol type shown in the left half of FIG.
[0005]
This door plate 5 is rotatably attached to a pivot 8 on the upper part of the main body frame 4 via a spring (not shown).
That is, the door plate 5 and the plate arm 11 can be rotated integrally using the pivot 8 and a spring (not shown).
Therefore, the door plate 5 moves only by moving the plate arm 11.
The upper end portions of the main body frame 4 and the door plate 5 are bent outward and formed in the coin slot 1 (see FIG. 7A).
A substantially rectangular plate shown in the right half of FIG.
A small cylindrical solenoid 16 is disposed on the cover plate 17.
[0006]
A lid plate 15 bent in an L shape is pivoted on the solenoid 16 upward.
Therefore, the slender coin drop hole 12 is opened and closed by turning the solenoid 16 on and off.
In addition, the code | symbol 13 shown by the right end of FIG. 7 (A) is a cover part, and is formed of a part of cover board 17. FIG.
The lid portion 13 and the main body frame 4 form an elongated coin outlet 2.
In the conventional coin rolling selector described above, a coin is inserted into the insertion slot 1.
[0007]
The inserted coin falls while rolling on the rail 7 formed on the lower edge of the main body frame 4 (see FIG. 7B).
When the coin A rolling on the rail 7 is authentic, the coin A is guided by the coin guide 10 and the door plate 5 and further rolled.
When the coin rolling on the rail 7 is not authentic and has a small diameter, it falls off the coin guide 10 or the door plate 5 and falls.
When the coin rolling on the rail 7 is not genuine and has a large diameter, it is stopped by the mounting plate 101 of the coin guide 10 or the like.
In this case, for example, when the door plate 5 is moved against a spring (not shown), the plate arm 11 also moves.
[0008]
Thus, the coin stopped by the mounting plate 101 or the like is dropped by the plate arm 11.
However, the above-described coin rolling selector has a problem that it is large in the lateral direction.
In addition, there is a problem that the mounting space becomes large in order to make the entire selector oblique when mounting.
Further, when changing the size of coins to be selected, there has been a problem that the selector has to be completely remodeled.
[Problems to be solved by the invention]
[0009]
The present invention was developed for the purpose of solving the above problems.
That is, the present invention has been developed for the purpose of reducing the overall size of the selector as much as possible.
In other words, the present invention has been developed for the purpose of enabling the entire selector to be mounted vertically without being inclined.
Further, the present invention has been developed for the purpose of facilitating the change of the diameter size of the selected coin.
In addition, the present invention was developed for the purpose of adding the function of a coin rolling selector.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a plate-shaped main body frame, an arc passage formed of a circle of about a quarter formed adjacent to the main body frame, and concentric with the arc center of the arc passage. And a roller that is rotatably and slidably mounted on the protruding shaft and has a groove having a Λ-shaped cross section formed on the circumferential surface thereof,
A window opened in the main body frame between the arc passage and the roller so that a small-diameter coin can fall down,
A pressing piece for pushing a coin toward the window relative to the window
This is a coin rolling selector having
[0011]
FIG. 1 is a perspective view schematically showing an embodiment according to the present invention.
FIG. 2 is a front view of FIG.
FIG. 3 is a schematic slope view of FIG. 1 as viewed obliquely from above.
4 is a rear view of FIG.
FIG. 5 is a partial view showing a portion from which the main part of FIG. 4 is removed.
FIG. 6 is a front view showing a part of FIG. 2 removed.
The coin rolling type selector according to an embodiment of the present invention is generally box-shaped as a whole (see FIG. 1).
Further, the selector of this embodiment is formed in a shape in which the entire box is inclined downward (see FIG. 2).
[0012]
When the selector is used, a coin is usually inserted from the upper acute angle portion and rolled toward the lower acute angle portion (see FIG. 6).
First, coins are inserted from the opening 21 formed at the top of the selector.
The coins inserted from the opening 21 are guided in rolling by an arc passage 22 that is about a quarter of a circle.
The arc passage 22 is formed by a slightly thick plate 23 shaped like a crane (see FIG. 6).
The crane-shaped plate 23 is fixed to a large main body frame 25 (see FIG. 6).
Furthermore, the crane-shaped plate 23 is covered with a slightly small door body 31 (see FIG. 5).
[0013]
The door body 31 is formed of a substantially pentagonal resin molded product and an L-shaped metal plate 31M.
The door body 31 is attached to the main body frame 25 so as to be freely opened and closed by a pivot 32 at the upper center.
An ax-shaped slightly larger window 27 is opened near the top of the main body frame 25 (see FIG. 6).
A crescent-shaped opening / closing plate 26 is pivoted on the edge of the window 27 near the arc passage 22 via a substantially Y-shaped arm plate 29 (see FIG. 4).
The opening / closing plate 26 and the arm plate 29 are for removing and canceling coins jammed in the passage as will be described later.
An operation piece 24 for opening and closing the door body 31 is formed at the long outer end of the arm plate 29 (see FIG. 4).
Of course, the operation piece 24 can penetrate the main body frame 25.
A slightly large arm 51 is formed outwardly at the center of the upper edge of the main body frame 25.
The arm 51 is further bent downward, and a projecting shaft 52 is fixed to the tip thereof (see FIG. 4).
The protruding shaft 52 protrudes toward the door body 31.
A roller 53 is rotatably mounted on the protruding shaft 52 via a spacer.
A groove 55 is formed on the entire circumference of the original end of the roller 53 (see FIG. 3).
[0015]
The groove 55 is used to slide the roller 53 in the direction of the projecting shaft 52 as will be described later.
Further, a groove 56 is formed on the entire circumference of the tip of the roller 53.
This groove 56 is for guiding the upper edge of the rolling coin as will be described later.
One of the side surfaces of the groove 56 is formed as an inclined surface.
In other words, a groove 56 having a substantially V-shaped cross section is formed in the roller 53.
As shown in the right part of FIG. 5, a J-shaped pressing piece 33 is pivoted and pivoted on the upper portion of the door body 31.
[0016]
The pressing piece 33 penetrates the door body 31 so as to be swingable, and presses the coin passing therethrough against the main body frame 25.
Therefore, the small spring 36 is arrange | positioned between the door body 31 and the pressing piece 33 (refer FIG. 5).
Further, a Γ-shaped stopper piece 37 is pivoted on the upper portion of the door body 31 and suspended.
The stopper piece 37 penetrates the door body 31 so as to be swingable.
And the passage of the coin which comes from the circular arc path 22 is blocked | prevented by the lower end part of the stopper piece 37 (refer FIG. 6).
A small rectangular body shown in the upper left part of FIG. 4 is a solenoid 61 in the arm 51.
[0017]
A small oval link (not shown) is pivotally attached to the plunger (not shown) of the solenoid 61. Further, an L-shaped link (not shown) is pivotally attached to the small link. A long spring piece 63 is pivotally attached 62 to the L-shaped link (see FIG. 3). A slightly long rod 65 is fixed to the lower surface of the distal end portion of the spring piece 63. The tip of the rod 65 is slidably inserted into the groove 55 of the roller 53 (see FIG. 3). Thus, when the solenoid 61 is turned on, the spring piece 63 is rotated around the pivot 62.
[0018]
As a result, the rod 65 moves and the roller 53 approaches the door body 31 as shown by the arrow in FIG.
In other words, the groove 56 of the roller 53 for guiding the coin corresponds to the arc path 22.
On the other hand, when the roller 53 approaches the door body 31, the protrusion 53 of the stopper piece 37 is pushed by the roller 53 (see FIG. 2).
Therefore, since the lower end portion of the stopper piece 37 is retracted, the coin from the arc passage 22 is further rolled (see FIG. 6).
In other words, coins from the arc passage 22 roll on the fixed rail 71 of the main body frame 25.
[0019]
Near the fixed rail 71, three sensors S for counting are arranged.
These sensors S detect a coin passing through the fixed rail 71, for example, magnetically or optically.
The reason why the number of sensors S is three is to prevent malfunction due to mischief.
A slightly large rectangular body shown on the left side of FIG.
A U-shaped movable rail 73 is rotatably disposed on the plunger of the solenoid 72 via a shaft 79 (see FIG. 4).
That is, each upper end portion of the U-shaped movable rail 73 is pivotally attached 77 to the main body frame 25.
[0020]
A pair of oblique holes are opened at the center of the movable rail 73 and the shaft 79 is penetrated (see FIG. 3).
Furthermore, a stopper 75 is formed on the movable rail 73 with an arm piece interposed. When the solenoid 72 is off, the movable rail 73 is located outside the main body frame 25.
The stopper 75 is located inside the main body frame 25.
That is, when the solenoid 72 is off, coins coming from the fixed rail 71 are blocked by the stopper 75 and fall into a safe (not shown) (see FIG. 6).
When the solenoid 72 is on, the movable rail 73 is positioned inside the main body frame 25.
[0021]
The stopper 75 is located outside the main body frame 25.
Therefore, when the solenoid 72 is on, the coin rolls on the movable rail 73 and is guided by the main body frame 25 to fall (see FIG. 1).
Coins that are guided by the main body frame 25 and fall are stored in, for example, a tank (not shown) of a hopper.
5 is a steel ball 91 for adjusting the coin passage.
The steel ball 91 is rotatable and disposed so as to be accessible to the main body frame 25.
That is, the steel ball 91 is for adjusting the width of the arc passage 22 according to the thickness of the coin inserted into the opening 21.
[0022]
The coin rolling selector of this embodiment having the above-described configuration is usually used with the solenoids 61 and 72 turned on. That is, the groove 56 of the roller 53 corresponds to the position of the arc passage 22. The movable rail 73 is located inside the main body frame 25. Of course, the stopper piece 37 is located outside the door body 31 and the stopper 75 is located outside the main body frame 25. When a coin is inserted into the opening 21 in this state, the coin is guided by the circular arc passage 22 and rolls and falls.
[0023]
When the coin is genuine, in other words, when the coin is a coin to be selected, the coin passes through the arc passage 22.
That is, the lower edge of the coin is guided by the arc passage 22 and the upper edge of the coin is guided by the groove 56.
Therefore, when the coin is genuine, the coin passes smoothly through the arc passage 22 and rolls further downward.
In this case, since the roller 53 is rotatable, the intrinsic coin passes smoothly and speedily.
Therefore, it is needless to say that the spring 36 has a weak elastic force.
[0024]
Of course, for example, the roller 53 may be rotated by a small electric motor (not shown).
In this case, for example, the pivot shaft 52 needs to have a rotatable mounting structure.
Of course, when the roller 53 is driven to rotate, the passing speed of the coins increases.
When the coin inserted into the opening 21 is not genuine and has a small diameter, the coin does not pass through the arc passage 22.
In this case, the lower edge of the coin is guided by the arc passage 22, but the upper edge of the coin is not guided by the groove 56.
[0025]
Therefore, coins having a small diameter are inclined and dropped inside the door body 31 and canceled, for example.
If a coin with a small diameter vibrates, it appears to be a true coin as the diameter increases.
In this case, the spring 36 acts to absorb the vibration of the coin.
Thus, if the diameter of the coin is small, it will be canceled out of the groove 56 of the roller 53.
Even when the coin inserted into the opening 21 is not genuine and has a large diameter, it does not pass through the circular arc passage 22.
[0026]
Although the lower edge of the coin is guided by the arc passage 22, the upper edge of the coin hits the roller 53.
In other words, when the diameter of the coin is large, the coin is held between the arc passage 22 and the roller 53 and cannot move.
In this case, a coin having a large diameter can be easily dropped and canceled by opening and closing the arm plate 29 about the pivot 28.
That is, the opening / closing plate 26 is moved by the operation of the arm plate 29, and at the same time, the door body 31 is opened / closed through the operation piece 24.
In this embodiment, a groove 56 having a substantially V-shaped cross section is formed in the roller 53.
In other words, when viewed from the circular arc passage 22, the groove 56 has a Λ cross section.
[0027]
In addition, since the cross-sectional shape only needs to be the Λ-shaped groove 56, for example, the groove 56 may be formed by two rollers.
Of course, the groove 56 may be formed in another member, for example, a semi-disc shape.
Further, the cross-sectional shape of the groove 56 is exactly one in the case of the present embodiment, but it goes without saying that it may be two.
Further, in the present embodiment, when the selected coin is changed, it can be performed only by replacing the roller 53.
For example, when the diameter of the selected coin is changed, it goes without saying that it can be performed by replacing the roller 53.
[0028]
Of course, the thickness of the selected coin can be changed by replacing the roller 53.
In this embodiment, the solenoids 61 and 72 are normally turned on for use.
However, as is apparent from the above, it can be used even if the solenoid 61 is turned on and the solenoid 72 is turned off.
For example, the solenoids 61 and 72 are turned on to use the first safe (not shown).
When the first safe is full, the solenoid 72 can be turned off to use the second safe (not shown).
[0029]
Needless to say, the solenoid 61 is normally turned on and can be turned off if there is a problem with the coin selector device. In this case, it goes without saying that even if the coin inserted into the opening 21 is genuine, it is canceled.
Further, the position of the solenoid 61 is brought close to the roller 53 and the operation mechanism of the rod 65 is changed. Then, the solenoid 72 is removed, and the main body frame 25, the arm 51, the metal plate 31M and the like in the vicinity thereof are removed.
As a result, although not shown, the coin selector of the present embodiment shown in FIGS. 2 and 4 can of course be halved in size.
[0030]
In the case of large coins, malfunction may occur if the stopper 75 is used as shown in FIG.
For example, this is a case where the next second coin C2 hits the first coin C1 when the first coin C1 hits the stopper 75 and swings.
In other words, the first coin C1 that is vibrating by hitting the stopper 75 may vibrate the second coin C2.
At this time, there is a problem that the sensor S detects the second coin C2 that vibrates, and further counts and erroneously counts.
The second embodiment shown in FIG. 8 solves this problem.
[0031]
That is, the fan-shaped guide 91 is pivoted 92 so as to be openable and closable with respect to the main body frame 25.
When the guide 91 is used, the guide 91 is brought into contact with the main body frame 25 by a spring (not shown) (see FIG. 8).
In this case, coins coming from the fixed rail 71 are smoothly dropped by the curved portion 93 formed on the outer edge of the guide 91.
In other words, when the solenoid 72 is off, the coin is blocked by the curved portion 93 of the guide 91 and falls into a safe (not shown).
When the solenoid 72 is on, the movable rail 73 is positioned inside the main body frame 25 (see FIG. 9).
[0032]
The guide 91 is separated from the main body frame 25 against a spring (not shown) by the movable rail 73 positioned on the inner side. Accordingly, the coin rolls on the movable rail 73 and further falls while being guided by the main body frame 25 (see FIG. 9). Coins that are guided by the main body frame 25 and fall are stored in, for example, a tank (not shown) of a hopper.
【The invention's effect】
As described above, according to the present invention, the size of the entire coin selector can be reduced only by adding a simple configuration.
[0033]
That is, according to the present invention, the size of the entire coin selector can be reduced by adopting the arc-shaped passage means. Further, according to the present invention, the size of the selected coin can be easily changed simply by replacing the coin guide roller. Further, according to the present invention, there is an advantage that the coin selector can be mounted vertically by adopting the arc-shaped passage means and the coin guide roller. In addition, since the present invention makes the coin guide roller movable, it is possible to obtain a great effect that coins can be selected at an early stage.
