Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin selector for selecting whether a coin is authentic or not while rolling it. More particularly, the present invention relates to a rolling coin selector used for a game machine such as a pachinko slot or a so-called pachislot. The term “coin” used in the present specification includes a small disc-shaped coin which is a currency. The term “coin” in the present specification includes, of course, disc-shaped medals and tokens used in the game.

2. Description of the Related Art Conventionally, coin rolling type selectors have been used for medal game machines, pachislot machines and the like.
No. -23240. In addition, actual application 4-23
The rolling type selector described in Japanese Patent No. 240 is 6-25
No. 963. In addition, actual application 4-
The rolling selector described in 23240 is patented by U.S. Pat. No. 5,293,981.

A rolling selector disclosed in Japanese Utility Model Application No. Hei 4-23240 is schematically shown in a perspective view of FIG.
FIG. 14 also shows a cross-sectional view of the coin rolling selector. In the rolling selector shown in FIG. 14, coins are inserted into the insertion slot 1 at the top. The inserted coin falls while rolling on the straight rail 7 formed on the lower edge of the large frame 4. If the coin A is genuine, the coin A is sandwiched between the thin plate guide 10 and the door plate 5 to continue rolling (see the sectional view of FIG. 14). When the coin A is not authentic and has a small diameter, it falls off the guide 10 or the door plate 5 and falls.

When the coin A is not authentic and has a large diameter, the coin A is stopped by the guide 10 or the like and does not roll. In this case, when the door plate 5 moves against a spring (not shown), the arm 11 also moves through the pivot 8. Thus, the coin stopped by the guide 10 or the like falls.

2. Description of the Related Art A significantly improved rolling selector is disclosed in Japanese Patent Application No. 10-324355 filed by the present applicant. The rolling selector described in Japanese Patent Application No. 10-324355 is disclosed in Japanese Patent Application Laid-Open No. 2000-123217.

A front view of the rolling selector disclosed in Japanese Patent Application No. 10-324355 is schematically shown in FIG. FIG. 16 is a schematic sectional view of FIG. 15 viewed from the left side. The rolling selector disclosed in Japanese Patent Application No. 10-324355 is used in the state shown in FIG. That is, a small groove 56 having a substantially V-shaped cross section is formed by the pair of rollers 53 and 55 for use. In this state, the coin C is inserted into the opening 21 above the selector.
The inserted coin C is guided and rolled by the arc path 22 (see FIG. 15).

[0006] When the coin C is a genuine coin to be selected, the coin C passes through the arc passage 22. That is, the lower edge of the genuine coin C is guided by the arc passage 22. At the same time, the upper edge of the genuine coin C is a pair of rollers 5
Guided by small grooves 56 of 3 and 55. Therefore, when the coin C is a genuine coin, the coin C passes through the arc passage 22 smoothly. In this embodiment, the pair of rollers 53 and 55 are rotatable. As a result, the genuine coin C passes through the arc passage 22 smoothly and speedily.

If the coin inserted into the opening 21 is not authentic, the coin does not pass through the arc path 22. For example, if the inserted coin has a small diameter, the coin does not pass through the arc passage 22. That is, when the inserted coin has a small diameter, the coin falls off the upper small groove 56. In addition, even if the coin has a small diameter, the appearance of the coin is increased when the coin is vibrating, and the coin looks like a genuine coin. In this case, the spring 57 operates (see FIG. 16).

That is, the spring 57 absorbs the vibration of the coin. As a result, the coin having a small diameter falls off the pair of rollers 53 and 55. Even when the diameter of the coin inserted into the opening 21 is large, the arc path 22
Will not pass through. For example, the upper edge of a large-diameter coin hits the pair of rollers 53 and 55 and is stopped. In this case, the coin having a large diameter falls by opening and closing the door 31 around the upper pivot 32.

[Problems to be solved by the invention]

However, the above-mentioned conventional coin rolling selector has a problem that it is large in the horizontal direction. In other words, the conventional rolling type coin selector has a problem that the overall size is large. In addition, the conventional rolling type coin selector has a problem that it is heavy because the parts are almost made of metal. The present invention has been developed for the purpose of solving the above problems. That is, the present invention has been developed to reduce the size of the entire selector as much as possible.

The present invention has been developed for the purpose of reducing the weight of the entire selector by using a synthetic resin molded product. Further, the present invention has been developed for the purpose of simplifying the size change accompanying the change of the sorting coin.

SUMMARY OF THE INVENTION The present invention provides at least a base (20) having an upright shape of a substantially square plank.
And a rail (22) provided on the base for allowing the inserted coin to stand up and roll, and a rail (22) rotatably disposed above the rail and mounted on the rolling coin. And a grooved roller (32) for guiding the rim.

The present invention is also a rolling coin selector wherein the rail is made of an elongated metal and is detachably fixed to the base. The present invention is also a rolling coin selector, wherein the roller is made of a synthetic resin molded product and is detachably provided on the base.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic perspective view of an embodiment according to the present invention as viewed obliquely from above and from above.
FIG. 2 is a front view of FIG. FIG. 3 is a schematic perspective view of the embodiment of FIG.

FIG. 4 is a rear view of FIG. FIG. 5 is a schematic perspective view showing the embodiment of FIG. 1 with a part thereof removed. FIG. 6 is a front view of FIG. FIG. 7 is a sectional view of FIG. 5 as viewed from above. FIG. 8 is also a cross-sectional view of FIG. 5 as viewed from above. The rolling coin selector according to one embodiment of the present invention is entirely in a vertical flat box state (see FIG. 1). In this embodiment, a substantially pentagonal cover body 50 is pivoted on a substantially square base 20.

The cover body 50 is formed of a hollow synthetic resin molded product, and FIG. 5 shows the cover body 50 with the cover body 50 removed. The coin is placed in the opening 21 formed in the upper corner of the selector.
It is thrown in from. A guide piece 19 that can be adjusted according to the diameter of the coin is screwed near the opening 21. The coin inserted through the opening 21 is guided to the outlet 24 by the rail 22 curved downward (see FIG. 5). That is, coins inserted from the upper corner of the selector are erected and rolled toward the furthest lower corner.

When the roll of the coin inserted from the upper corner of the selector is stopped, the coin is dropped to the nearest lower corner. That is, when the rolling of the coin inserted through the opening 21 is stopped, the coin falls into the cancel path 28 thereunder. The elongated metal rail 22 is detachably fixed to the base 20 made of a resin molded product. The rail 22 is fitted into the narrow groove curved downward from the upper corner to the lower corner far from the upper corner against the elasticity. The base 20 near the opening 21 is provided with a substantially fan-shaped window 23 having a slightly large depression (see FIG. 6).

At the lower edge of the window 23, a slightly large roughly cross-shaped canceling body 25 is pivoted at 26 (see FIG. 3). The crescent piece 25M, which is one lateral end of the canceling body 25, is arranged so as to open and close the window 23. The canceling member 25 of the resin molded product is for removing and canceling a coin stuck in the apparatus. A projection 25P is formed at the tip of the L-shaped upper end 25T of the canceling body 25 (see FIG. 9). The projection 25P is used as an operation piece for opening and closing the cover body 50 against the spring.

The upper end 25T of the canceling body 25 is substantially inserted into the grooved square case 25C of the base 20. A metal protruding shaft 31 is fixed to the cover 20 at the base 20 which is a key position of the fan-shaped window 23. Further, a substantially L-shaped cancel lever 27 shown in the upper part of FIG. The cancel lever 27 is rotatably mounted on the outer end of the protruding shaft 31. When the lever 27 is rotated around the protruding shaft 31, the canceling body 25 is rotated about the pivot 26.

As a result, the window 23 is opened and closed by the crescent piece 25M of the canceling body 25. A roller 32 made of a resin molded product is rotatably and detachably mounted on the inner end of the protruding shaft 31. A groove 33 having a substantially U-shaped cross section is formed all around the outer end of the roller 32 (see FIG. 5). This groove 33 is for guiding the upper part of the peripheral edge of the standing coin rolling on the rail 22. Groove 33
The top surface of the outer side is formed as an inclined surface. This is because the outer edge of the coin is guided by the groove 33 of the roller 32.

As described above, the cover body 50 is formed of a hollow substantially pentagonal resin molded product. The upper part of the cover body 50 is attached to the upper part of the base body 20 by a pivot 51 and a spring so as to be freely opened and closed. Further, a slightly small J-shaped pressing piece 53 is pivoted at the upper portion of the cover body 50 at each upper portion (see the right side in FIG. 2). The pressing piece 53 of the resin molded product penetrates the cover body 50 in a swingable manner. The pressing pieces 53 lightly press the passing coin against the base 20 to absorb the vibration of the coin.

Therefore, a small spring 56 is arranged between the cover body 50 and the pressing piece 53 (FIG. 2).
See). A slightly larger Γ-shaped holding piece 57 is swingably suspended from the pivot 55. The pressing piece 57 of this resin molded product allows the roller 32 to be
Press lightly to zero. In other words, the roller 32 is accurately positioned by the projection 54 at the center of the pressing piece 57. Therefore, a small spring 58 is disposed between the holding piece 57 and the cover body 50 (see FIG. 2).

The long holding piece 57 is free from the cover body 50 by the spring 58. That is, even when the cover body 50 is opened and closed at the time of cancellation or the like, the holding piece 57 is stationary. Thus, even if the cover body 50 is opened and closed, the coin is guided to the cancel path 28 by the holding piece 57. A small spherical body 59 is disposed inside the center of the cover body 50 (see FIG. 2). The spherical body 59 is provided so as to be able to approach and separate from the base 20.

The spherical body 59 is used to adjust the width of the coin passage corresponding to the thickness of the genuine coin. The small rectangular body shown in the lower left part of FIG.
An oval small link 62 is pivotally connected to the plunger of the solenoid 61. Further, a longitudinal axis 63 is pivotally attached to the tip of the link 62. A substantially F-shaped gate 65 made of a synthetic resin molded product is fixed to the lower end of the vertical axis 63. The lower end of the gate 65 is located at the base 20.
(See FIG. 4). This gate 65
The upper end 67 can protrude above the rail 22 (see FIGS. 7 and 8).

A substantially arcuate sub-gate 72 is further pivotally mounted on the pivot 26 (see FIG. 3). A small spring (not shown) is arranged between the sub-gate 72 of the resin molded product and the cancel body 25. And F
The central piece of the shaped gate 65 is freely contactable with the base end 71 of the sub-gate 72. Thus, when the solenoid 61 is turned on, the gate 65 is rotated about the pivot 66 against the spring. As a result, the upper end 67 of the gate 65
Moves away from above the rail 22 (see FIG. 7).

At the same time, the central piece of the gate 65 is
The sub-gate is moved by contacting the base end 71 of the second sub-gate 2 (see the chain line in FIG. 7). The coins thus inserted pass through the rail 22 without being blocked by the gates 72 and 67. That is, when the solenoid 61 is on, the coin rolls on the rail 22 and is guided to the outlet 24. The coin guided by the exit 24 is stored, for example, in a safe (not shown). When the solenoid 61 is turned off, a spring acts to rotate the gate 65 about the pivot 66.

As a result, the upper end 67 of the gate 65 is located above the rail 22 (see FIG. 8). At the same time, the central piece of the gate 65 is separated from the base end 71 of the sub-gate 72. The sub-gate 72 is free and located above the rail 22 by the action of a spring (not shown). Thus, the coin inserted through the opening 21 is guided to the cancel path 28 by the sub gate 72 (see FIG. 5).
Therefore, the upper end 67 of the gate 65 is not damaged by the coin. Further, there is a case where the inserted coin is canceled when passing through the position of the sub-gate 72.

Even in this case, the coin is reliably guided to the cancel path 28 by the upper end 67 of the gate 65. That is, when the solenoid 61 is off, the rail 22
The genuine coin that moves is also stopped and falls. A coin counting sensor S is appropriately disposed near the lower end of the rail 22 (see FIG. 6). These sensors S detect coins passing through the rail 22 magnetically or optically, for example.

【Example】

The rolling selector according to the present embodiment having the above-described structure is normally used with the solenoid 61 turned on. That is, the upper end 67 and the sub-gate 72 of the gate 65 are removed from above the rail 22 and used (see FIG. 7). When the coin is inserted into the opening 21 in the above state, the coin stands up and rolls along the rail 22. Thus, when the coin that stands and rolls is genuine, it passes through the rail 22. That is, when the coin is a coin to be sorted, the coin passes through the rail 22. The lower edge of the rolling coin is guided by the rail 22 and the upper edge thereof is guided by the groove 33 of the roller 32 (see FIG. 5).

Therefore, when the coin is genuine, the coin smoothly passes through the rail 22 and rolls further downward. In this case, since the roller 32 is rotatable, the genuine coin passes smoothly and speedily. Therefore, it is needless to say that the springs 56 and 58 are preferably weakly elastic (see FIG. 2). If the coin inserted into the opening 21 is not authentic and has a small diameter, the coin does not pass through the rail 22. In this case, the lower edge of the coin is guided by the rail 22, but its upper edge is not.

Therefore, coins having a small diameter are separated from the rail 22 and fall into the cover body 50, that is, into the cancel path 28. In addition, if a coin having a small diameter is oscillating, apparently, the diameter becomes large and it looks like a genuine coin. In this case, the spring 56 acts to absorb the vibration of the coin. Thus, when the diameter of the coin is small, the coin is detached from the roller 32 and is reliably 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 long rail 22.

The lower edge of the coin having the large diameter is guided by the rail 22, but the upper edge of the coin hits the roller 33. In other words, if the diameter of the coin is large, rail 2
The roller does not roll because it is clogged between the roller 2 and the roller 32. In this case, the coin is dropped on the cancel path 28 by moving the cancel body 25 about the pivot 26. That is, the operation of the cancel body 25 moves the crescent plate 25. At the same time, the cover 50 is
Is opened and closed. In the present embodiment, the guide inclined surface of the groove 33 of the roller 32 is one, but it is needless to say that two may be provided.

In the present embodiment, the change of the selected coin can be performed only by replacing the roller 32. For example, when the diameter of the selected coin is changed, the change can be performed by replacing the roller 32. In addition, when the thickness of the selected coin is changed, it is needless to say that the thickness can be changed by replacing the roller 32. Also, the solenoid 61 can of course be turned on during use and turned off if there is a problem. In this case, it goes without saying that even if the coin inserted into the opening 21 is genuine, the coin is canceled.

FIG. 9 is a front view schematically showing a second embodiment according to the present invention. FIG. 10 is an exploded perspective view of FIG. Note that the reference numerals used in FIGS. 1 to 8 are used as reference numerals in the drawings. That is, the same reference numerals are used for the parts where the parts of the second embodiment are the same as those of the first embodiment. The feature of this second embodiment is a roughly caudal fin-shaped shoot 10 as is apparent from the drawing. The chute body 10 is made of a synthetic resin molded product having a little elasticity and can be attached to the base 20 freely.

The chute 10 is connected to the outlet 24 of the base 20.
It is used to guide the coin ejected from the camera to a desired position. The chute body 10 is roughly divided into a bottom plate portion 9 and a guide plate portion 7 which is erected and coupled to the bottom plate portion 9. The elongated bottom plate 9 is formed obliquely so as to be flush with the rail 22 on the opening 24 side (see FIG. 9). The slightly longer guide plate 7 is erected on one side of the bottom plate 9 and its lower end is curved. A pair of male parts 6 constituting a connecting means are connected to the upper end of the guide plate part 7.

Each male portion 6 has a pair of guide pieces 5 each forming a hollow triangular pyramid. Further, each male portion 6 has a slightly smaller L between the pair of guide pieces 5.
It has a hook piece 3 in the shape (see FIG. 10). The guide piece 5 and the hook piece 3 each have elasticity. The pair of female parts constituting the above-mentioned connecting means are formed near the outlet 24 of the base 20 respectively. Each female part has a trapezoidal hole 12 for receiving a pair of guide pieces 5.
have.

Each female part has a pair of tapered walls 13 for guiding a pair of guide pieces 5 to be inserted. Further, each female portion has a stopper wall 15 for retaining and holding the male portion 6. Thus, when attaching the chute body 10 to the base body 20, first, each male part 6 is inserted into each hole 12. Specifically, a pair of guide pieces 5 having a hollow conical shape are inserted into the trapezoidal holes 12 against elasticity. Therefore, the shoot body 10 can be accurately attached to the base 20 without considering the front and back.

Next, the tip of the hook 3 is pressed into the hole 12 while the chute 10 is pressed against the base 20. In other words, the hook piece 3 while pressing the shoot body 10
Into the hole 12 against the elasticity. Hook piece 3
When the leading end of the male part 6 is inserted into the hole 12, almost the entire male part 6 passes through the hole 12. Thus, the hook piece 3 that has passed through the hole 12 is hooked on the stopper wall 15 by the elastic restoring force. That is, the hook 3 is hooked on the stopper wall 15 so that the chute 10 is prevented from coming off the base 20.

When detaching the chute 10 from the base 20, the chute 10 is first kept away from the base 20. In this state, the tip of the hook piece 3 is pushed down against the elasticity. In other words, the hook piece 3 is removed from the stopper wall 15 and pushed into the hole 12 while being pushed down. When the tip of the hook piece 3 enters the hole 12, the male part 6 smoothly separates from the female part. As a result, the shoot body 10 is
0 (see FIG. 10).

FIG. 11 is a front view schematically showing a third embodiment according to the present invention.

FIG. 12 is a schematic sectional view of FIG. 11 as viewed from the right side slightly below. FIG. 13 is a perspective view and a front view showing a main part of the third embodiment. Note that the reference numerals used in FIGS. 1 to 8 are used as reference numerals in the drawings. That is, the same reference numerals are used for the portions where the portions of the third embodiment are the same as those of the first embodiment. The feature of this third embodiment is a prism having a substantially roof shape (see FIG. 13). This prism is made of a transparent synthetic resin molded product and has a rectangular thin plate mounting plate portion P0. At one end of the mounting plate portion P0, a first reflecting portion P1 whose end face is substantially a right triangle is coupled.

Further, a second reflecting portion P2 whose end face is substantially a right triangle is connected to the leading edge of the first reflecting portion P1. In other words, the roof-shaped second reflector P2 is located above the center of the rectangular mounting plate P0. That is, the roof-shaped second reflector P2 is located on the mounting plate P0 with the passage PS interposed therebetween. Prism mounting plate P
0 is mounted on a slightly larger electronic circuit board CB against elasticity (see FIG. 16). The substrate body CB has three light emitting elements LE and three light receiving elements R1, R2,
R3 is exposed.

Each of these three light emitting elements LE emits light to the first reflecting portion P1. The light emitted by each light emitting element is first reflected by the first reflecting portion P1. The light reflected by the first reflector P1 is further reflected by the second reflector P2. Each light reflected by the second reflector P2 passes through the path PS. After passing through the path PS, each light is respectively transmitted to the light receiving element R
1, R2, R3. The substrate CB having the prism is attached to the base 20 behind the roller 32 against the elasticity (see FIG. 11).

The genuine coin coming up and rolling on the rail 22 has its upper edge passing through the path PS.
When a genuine coin passes through the path PS, it passes through the two light receiving elements R1 and R2 for counting coins. The third light receiving element R3 is used to prevent misconduct such as mischief. When the third light receiving element R3 detects something, for example, the device (not shown) provided with the selector is stopped. A long Z-shaped one shown below the substrate body CB with the prism is a metal plate MT for preventing fraud.

The metal plate MT is fixed so that the upper end thereof forms a prism path PS (see FIG. 12). The metal plate MT prevents a space from being formed near the passage PS when the cover body 50 is opened due to cancellation or the like. In other words, the metal piece MT is provided so that the coin counting light receiving elements R1 and R2 are not mischievous from the outside.

As described above, according to the present invention, the size of the entire selector can be reduced only by combining simple configurations.

In the present invention, the weight of the entire selector can be reduced only by combining a simple configuration. 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, since the rail can be removed, even if dirt is generated, it can be easily replaced.
