DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin rolling selector for sorting inserted coins while rolling the coins. 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. Note that the term “coin” in the present specification naturally includes a small disc-shaped coin which is a currency. Further, the term “coin” in the present specification includes, of course, disc-shaped medals and tokens used in games and the like.

[0002]

2. Description of the Related Art Various types of coin rolling selectors used in medal game machines and pachislot machines have been developed. For example, the present applicant has filed a Japanese Utility Model Application Hei 6-259.
No. 63 (Japanese Utility Model Application No. Hei 4-23240) discloses such a selector. FIG. 7 schematically shows a coin rolling selector disclosed in Japanese Utility Model Laid-Open No. 6-25963. Japanese Utility Model Application No. 4-2240 is disclosed in U.S. Pat.
293, 981 is added here.

FIG. 7A is a schematic perspective view of the whole of the selector as viewed from substantially the upper left. FIG. 7B is a schematic sectional view of the selector as viewed from the side. FIG.
The selector of (A) has a large main body frame 4 that is long horizontally. Each end of the body frame 4 has a mounting piece 1
9 and 18 are respectively formed. By these mounting pieces 19 and 18, the main body frame 4 is entirely fixed in the pachislot machine in an inclined manner. That is, the main body frame 4 is fixed with the length direction oblique and the width direction also oblique with respect to the horizontal plane (see FIG. 7B).

A slightly large rectangular window 9 is opened substantially below the center of the main body frame 4. A thin rectangular rectangular coin guide 10 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-shaped one shown in the left half of FIG.

[0005] The door plate 5 is rotatably mounted on a pivot 8 above the main body frame 4 via a spring (not shown). That is, the pivot 8 and the spring (not shown)
The door plate 5 and the plate arm 11 can be integrally rotated by utilizing the above. Therefore, only by moving the plate arm 11, the door plate 5 also moves. The upper ends of the main body frame 4 and the door plate 5 are each bent outward to form a coin insertion slot 1 (see FIG. 7A). The substantially rectangular one shown in the right half of FIG. A small cylindrical solenoid 16 is arranged on the cover plate 17.

The solenoid 16 has an L-shaped bent cover plate 15 pivoted upward. Therefore, by turning the solenoid 16 on and off, the elongated coin drop hole 12
Will be opened and closed. Reference numeral 13 shown at the right end of FIG. 7A indicates a cover, which is formed by a part of the cover plate 17. The lid 13 and the main body frame 4 form an elongated coin outlet 2. In the above-described conventional coin rolling selector, coins are inserted into the insertion slot 1.

The inserted coin falls while rolling on a rail 7 formed on the lower edge of the main body frame 4 (FIG. 7).
(See (B)). When the coin A rolling on the rail 7 is genuine, the coin A is guided by the coin guide 10 and the door plate 5 and continues rolling. 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 authentic and has a large diameter, the coin 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-mentioned coin rolling selector has a problem that it is large in the horizontal direction. In addition, there is a problem that the mounting space becomes large because the entire selector is inclined when mounting. In addition, when changing the size of coins to be sorted, there is a problem that the selector must be completely remodeled.

[Problems to be solved by the invention]

The present invention has been developed for the purpose of solving the above problems. That is, the present invention has been developed for the purpose of minimizing the size of the entire selector as much as possible. In other words, the present invention has been developed for the purpose of allowing the entire selector to be mounted vertically without being inclined. Further, the present invention has been developed for the purpose of easily changing the diameter size of the sorted coins. In addition, the present invention has been developed for the purpose of adding the function of the coin rolling selector.

The present invention has been developed for the purpose of eliminating malfunction of the sensor.

SUMMARY OF THE INVENTION According to the present invention, there is provided an arcuate passage means for rolling inserted coins by a peripheral edge, and for guiding an upper edge of the coin rolling on the passage means. And a groove means having a substantially rectangular cross section, wherein the groove means is movable at least to a position corresponding to the passage means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings.

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 perspective view of FIG. 1 viewed from obliquely above. FIG. 4 is a rear view of FIG. FIG. 5 is a partial view showing a part of FIG. 4 from which a main part is removed. FIG. 6 is a front view showing a part of FIG. A coin rolling selector according to an embodiment of the present invention has a generally box shape that is long horizontally (see FIG. 1). Further, the selector of this embodiment is formed so that the entire box is inclined downward (see FIG. 2).

When the selector is used, coins are usually inserted from the upper acute angle portion and rolled toward the lower acute angle portion (see FIG. 6). First, a coin is inserted through an opening 21 formed at the top of the selector. Opening 2
The coins inserted from 1 are guided to roll by the arc path 22 which becomes about a quarter circle. In addition, arc passage 2
2 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). Further, the crane-shaped plate 23 is covered with a slightly smaller door body 31 (see FIG. 5).

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 openable and closable by a pivot 32 at the upper center. An ax-shaped slightly large window 27 is opened near the top of the main body frame 25 (see FIG. 6). A crescent-shaped opening / closing plate 26 is provided on the edge of the window 27 near the arcuate passage 22 in a substantially Y-shaped arm plate 2.
9 are pivoted 28 (see FIG. 4). The opening / closing plate 26 and the arm plate 29 are for removing and canceling a coin stuck in the passage as described later.

An operation piece 24 for opening and closing the door body 31 is formed at a long outer end of the arm plate 29 (see FIG. 4). The operation piece 24 can of course penetrate the main body frame 25. A slightly large arm 51 is formed outward in the center of the upper edge of the main body frame 25. The arm 51 is further bent downward, and a protruding shaft 52 is fixed to a tip portion thereof (see FIG. 4). Note that the protruding shaft 52 protrudes toward the door body 31. Protruding shaft 5
A roller 53 is rotatably mounted on 2 via a spacer. A groove 55 is formed all around the original end of the roller 53 (see FIG. 3).

The groove 55 is for sliding the roller 53 in the direction of the protruding shaft 52 as described later. Further, a groove 56 is formed all around the distal end of the roller 53. The groove 56 is for guiding the upper edge of the rolling coin as 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 at the upper part of the door body 31 so as to hang down.

The pressing piece 33 penetrates the door body 31 so as to swing freely, and presses the passing coin against the main body frame 25. Therefore, a small spring 36 is arranged between the door body 31 and the pressing piece 33 (see FIG. 5). Further, a ス ト ッ パ -shaped stopper piece 37 is pivoted at the upper portion of the door body 31 so as to hang down. Note that the stopper piece 37 penetrates the door body 31 so as to swing freely. The lower end of the stopper piece 37 prevents the coin coming from the arc passage 22 from passing (see FIG. 6). The small rectangular body shown in the upper left part of FIG.
It is one.

A small oval link (not shown) is pivotally connected to a plunger (not shown) of the solenoid 61.
Further, an L-shaped link (not shown) is pivotally connected to the small link. A long spring piece 63 is pivotally attached 62 to the L-shaped link (see FIG. 3). Spring piece 63
A slightly long rod 65 is fixed to the lower surface of the distal end of the rod. The tip of the rod 65 is the groove 5 of the roller 53 described above.
6 and is slidably inserted into the inner space 6 (see FIG. 3). When the solenoid 61 is turned on, the spring piece 63 is turned on.
Is pivoted about a pivot 62.

As a result, the rod 65 moves and the roller 5
3 will approach 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 pressed by the roller 53 (see FIG. 2). Therefore, the coin from the arc passage 22 rolls further because the lower end of the stopper piece 37 is retracted (see FIG. 6). In other words, the arc passage 22
Will roll on the fixed rail 71 of the main body frame 25.

Note that three sensors S for counting are arranged near the fixed rail 71. These sensors S detect coins passing through the fixed rail 71, for example, magnetically or optically. The number of the sensors S is set to three in order to prevent malfunction due to mischief. A slightly larger 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 of the U-shaped movable rail 73 is pivotally attached 77 to the main body frame 25.

A pair of oblique holes are opened at the center of the movable rail 73, and a shaft 79 is penetrated (see FIG. 3). Further, 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 located inside the main body frame 25.

The stopper 75 is located outside the main frame 25. Therefore, when the solenoid 72 is on, the coin rolls on the movable rail 73 and is further guided by the main body frame 25 to drop (see FIG. 1). The coins that are guided by the main body frame 25 and fall are stored, for example, in a tank (not shown) of a hopper. The small circle shown in the approximate center of FIG. 5 is a steel ball 91 for adjusting the coin passage. The steel ball 91 is rotatable and arranged 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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The coin rolling selector according to the present embodiment having the above-described structure is normally 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. The stopper piece 37
Is located outside the door body 31 and the stopper 75 is located outside the body frame 25 as a matter of course. When a coin is inserted into the opening 21 in this state, the coin rolls and falls while being guided by the arc path 22.

When the coin is authentic, 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 the groove 56.
Guided by Therefore, when the coin is authentic, the coin smoothly passes 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 preferably has a weak elastic force.

The roller 53 may be rotated by a small electric motor (not shown). In this case, for example, the pivot 52 needs to have a rotatable mounting structure. When the roller 53 is driven to rotate, the passing speed of the coin is increased. When the coin inserted into the opening 21 is not authentic 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 path 22, but the upper edge of the coin is not guided by the groove 56.

Therefore, a coin having a small diameter falls, for example, obliquely, falls inside the door body 31, and is canceled. In addition, if a coin having a small diameter is oscillating, apparently, the diameter becomes large and the coin looks like an authentic coin. In this case, the spring 36 acts to absorb the vibration of the coin. Thus, when the diameter of the coin is small, the coin comes off the groove 56 of the roller 53 and is canceled. Even when the coin inserted into the opening 21 is not authentic and has a large diameter, the coin does not pass through the arc passage 22.

Although the lower edge of the coin is guided by the arc path 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 path 22 and the roller 53 and cannot be moved. In this case, by opening and closing the arm plate 29 about the pivot 28, a coin having a large diameter can be easily dropped and canceled. That is, the operation of the arm plate 29 causes the opening and closing plate 26 to move, and at the same time, the door body 3
1 is opened and closed. 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 arc passage 22, the groove 56 has a Λ-shaped cross section.

Since it is sufficient that the groove 56 has a Λ-shaped cross section, the groove 56 may be formed by, for example, two rollers. Of course, the groove 56 may be formed in another member, for example, in a semi-circular shape. Further groove 5
In the present embodiment, the cross-sectional shape of 6 is exactly one inclined surface, but it is a matter of course that two inclined surfaces may be used. In this embodiment, when changing the selected coin, the roller 53
Can be done simply by replacing For example, when the diameter of the selected coin is to be changed, it is needless to say that the change can be performed by replacing the roller 53.

It is needless to say that the thickness of the selected coin can be changed by replacing the roller 53. In the present embodiment, the solenoids 61 and 72 are normally turned on and used. However, as is clear from the above, the solenoid 61 is turned on and the solenoid 72 is turned on.
Can be used even if is turned off. For example, the solenoids 61 and 72 are turned on, respectively, to use a first safe (not shown). When the first safe is full, the solenoid 72 can be turned off to use the second safe (not shown).

The solenoid 61 is normally turned on, and can be turned off if there is a trouble in a device using the selector. In this case, it goes without saying that even if the coin inserted into the opening 21 is genuine, the coin is canceled. Further, the position of the solenoid 61 is made closer to the roller 53 and the operating mechanism of the rod 65 is changed. Then, the solenoid 72 is removed, and the body frame 25, the arm 51, the metal plate 31M, and the like near the solenoid 72 are removed.
As a result, although not shown, the collector of this embodiment shown in FIGS. 2 and 4 can of course be reduced to about half the size.

In the case of a large coin, a 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 vibrating on the stopper 75 may vibrate the second coin C2. At this time, there is a problem that the sensor S detects the oscillating second coin C2 and further counts and erroneously counts. The second embodiment shown in FIG. 8 solves this problem.

That is, the fan-shaped guide 91 is pivotally mounted on the main frame 25 so as to be freely opened and closed. Guide 9
When 1 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, the coin coming from the fixed rail 71 falls smoothly 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 located inside the main body frame 25 (see FIG. 9).

The guide 91 is separated from the main body frame 25 against a spring (not shown) by the movable rail 73 located inside. Therefore, the coin moves on the movable rail 73.
, And falls by being guided by the main body frame 25 (see FIG. 9). The coins that are guided by the main body frame 25 and fall are stored, for example, in a tank (not shown) of a hopper.

As described above, according to the present invention, the size of the entire collector can be reduced only by adding a simple structure.

That is, according to the present invention, the size of the entire collector can be reduced by employing the arc-shaped passage means. Further, according to the present invention, the size of the sorted coin can be easily changed only by replacing the roller for the coin guide. Further, according to the present invention, there is an advantage that the selector can be mounted vertically by employing the arc-shaped passage means and the coin guide roller. In addition, according to the present invention, since the coin guide roller is made movable, a great effect is obtained that the coin can be selected at an early stage.
