Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin sorter for mechanically sorting a specific type of coin and other coins or false coins without using electronic parts.

[0002]

2. Description of the Related Art In a vending machine that sells goods by receiving coins and a game machine that provides games by receiving coins, the inserted coins are inserted from the coin slot. It is important to select whether it is a proper coin (hereinafter referred to as a selection target coin) or another coin or a false coin (hereinafter referred to as another coin, etc.).

As described above, when a specific type of coin to be sorted is selected from other coins and the like, a power source is required for using electronic parts, and in particular, vending machines and the like. When installing the equipment outdoors, it is necessary to take measures to protect the electronic circuits, which makes maintenance thereof difficult.

Therefore, in the above case, a method of mechanically selecting coins without using electronic parts is preferable. As a mechanical coin sorting device of this type, a device as shown in FIG. 21 has been conventionally provided.

In FIG. 21, 1 is a coin slot,
In this case, the coin slot 1 is, as shown in FIG.
It is a vertically long opening. The dimensions d and w of this coin slot 1 are
The diameter and thickness of the coin to be selected are selected to be slightly larger than those of the coin to be selected so that other coins having a size larger than that of the coin to be selected cannot be inserted.

A coin sorting track 2 is formed at the back of the coin slot 1. A coin sorting mechanism 3 is provided in the coin sorting track 2 to sort the selection target coins that can be inserted from the coin slot 1 and other coins smaller than the coins.

The coin sorting mechanism 3 is composed of two arms 12a and 12b connected by a connecting portion 11 with a predetermined angular interval. As shown in FIG. 23, which is a side view of the coin sorting mechanism 3, the connecting portion 11 is rotatably attached to a shaft 13 attached to the wall 2a of the coin sorting track 2.

Shafts 15a and 15b are attached to the tips of the arms 12a and 12b in a direction orthogonal to the direction of rotation, and rollers 16a and 16b are rotatably attached to the shafts 15a and 15b.

Also, these two arms 12 and 13 are
For example, the home position is always biased to the stopper 14 side by the spring 17 so that the position of the roller 16b at the tip of the arm 12b is slightly lower than the position of the roller 16a at the tip of the arm 12a. .

At the home position, the horizontal distance r0 between the inner surfaces of the rollers 16a and 16b facing each other is set to be slightly smaller than the diameter of the coin to be sorted.

In such a structure, the coin slot 1
When the coin inserted from is a target coin to be sorted, the diameter R thereof is larger than the distance r0 between the rollers 16a and 16b, so that the target coin 18 to be sorted has two arms 12a as shown in FIG. , 12b. The weight of the coin 18 causes the arm 12a,
12b rotates in the direction of the arrow, and coin 1
8 drops onto the true coin orbit 4 and activates a predetermined mechanical switch or the like, for example, with a predetermined weight of the coin to be sorted. When the coin 18 separates from the arms 12a and 12b and falls, the bias springs 17 return the arms 12a and 12b to their home positions.

On the other hand, when another coin or the like 19 having a diameter r1 smaller than that of the coin to be sorted has come into the coin selecting path from the coin slot 1, the other coin is, as shown in FIG. 24B. Etc. 19 pass between the rollers 16a and 16b, are guided to the return track 5, and are returned to, for example, the return port.

[0013]

As described above, according to the conventional coin sorting apparatus shown in FIGS.
When coins or the like are inserted for each coin, it is possible to mechanically select the selection target coin and another coin or the like having a different size.

However, at the positions shown in FIG. 24C before the arms 12a and 12b return to the home position by the biasing force of the biasing spring 17, coins and the like are continuously loaded from the coin slot 1.
When coins or the like fall on the portions a and 12b, the horizontal distance r of the inner side surface of the rollers 16a and 16b
Since 2 is r2 <r0, even if another coin 19 or the like having a smaller size than the selected coin, the arms 12a,
Mis-selection that is supported between 12b and guided to the true coin orbit 4 will occur.

Further, in the case of the above-described conventional coin sorting device, there is also a drawback that if another coin or the like has the same size as the coin to be selected, it cannot be sorted.

It is an object of the present invention to provide a mechanical coin sorting device which does not have the above-mentioned drawbacks.

[0017]

In order to solve the above-mentioned problems, the coin sorting apparatus according to the present invention makes it possible to insert a coin having a size larger than that of a coin to be sorted having a specific size, by making reference numerals of the embodiments described later correspond to each other. A coin slot 21 having an opening for blocking, and a coin passage 31 having a predetermined descending slope through which a coin or the like passing through the coin slot 21 moves.

A second opening 38, which is provided at the position of the guide wall 33 that is further advanced, for guiding the coins to be sorted to the second coin orbit 42.
With.

When viewed from the coin slot 21, the first opening 35
Of coins that have passed through the coin slot 21
It is preferable to provide a movement path regulation plate 36 that biases the movement path on the coin passage 31 toward the first opening 35 side.

When the coin to be sorted is made of a non-magnetic material, the permanent magnet 60 is used in the present invention to further sort the false coin. That is,
A coin insertion slot 21 having an opening for preventing the insertion of a coin of a size larger than that of a particular size of non-magnetic material to be sorted, and a coin having a predetermined descending slope through which the coins passing through the coin insertion slot 21 move. A passage 31 and a guide wall 33 provided along the coin passage 31 for guiding the movement of coins, a coin provided in the middle of the coin passage 31 of the guide wall 33, and a coin having a size smaller than the coin to be sorted, First for guiding the return track 43 connected to the return port 23
Of the first opening 3 when viewed from the opening 35 of the
The second opening 38 provided at the position of the guide wall 33 preceding the reference numeral 5 for guiding a coin or the like having the same size as the coin to be selected to the material selection track 42, and the coin to be selected provided in the material selection track 42. And other coins etc. are magnetically selected,
The non-magnetic material selection target coins are guided to the true coin orbit, and the other coins made of the magnetic material and the like are provided to the material return selection means including the permanent magnet 60.

[0020]

In the coin sorting apparatus according to the present invention having the above-mentioned structure, another coin or the like having a size larger than the coin to be sorted cannot be thrown in from the coin slot, so that the coin is sorted at the time of throwing.

Among the coins inserted from the coin slot, other coins having a size smaller than that of the coin to be sorted are guided from the first opening to the first coin orbit, which is a return orbit, for example. , Selected. At this time, when the movement path regulation plate is installed between the coin insertion slot and the first opening, the coins and the like always take a movement path that is biased toward the first opening side, so Other small-sized coins and the like are reliably guided to the first coin orbit from the first opening.

Therefore, it is a coin or the like having the same size as the coin to be sorted which is guided to the second coin orbit from the second opening located at a position preceding the first opening.

If the second coin orbit guided by the second opening is a material selection orbit, the same coins as the objects to be selected are selected by the material selection means provided with a permanent magnet in the material selection orbit. When the other coin or the like having a size is a magnetic body, the other coin or the like is attracted by the permanent magnet and guided to the return track.

In the case of creating a fake coin having the same size and weight as the selected coin, considering the distribution price value of the coin and the production cost, inexpensive iron, which is a magnetic material, is used as the material. Mostly used. Therefore, the fake coin or the like made of the magnetic material is reliably sorted by the material sorting means using the permanent magnet,
It is led to the return orbit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a coin sorting device according to the present invention will be described below with reference to FIGS.

FIG. 8 is a front view of an example of an automatic vending machine to which the coin sorting device according to the present invention is applied. The vending machine in this example is a dedicated machine for 500-yen coins. That is,
In this vending machine, when a 500-yen coin is inserted through the coin slot 21, for example, a product providing mechanism using the weight of the 500-yen coin is activated and the button 22 is popped out. When the purchaser pushes this button 22, a product with a price of 500 yen appears at the product outlet 23. A well-known mechanism can be used as the merchandise providing mechanism for ejecting the merchandise to the merchandise outlet 23 by pushing out the button 22 by using the weight of the 500-yen coin and pushing the button 22.

Also in this case, the dimensions d0 and w0 of the opening of the coin slot 21 are selected to be slightly larger than the diameter r and the thickness t of the 500-yen coin. Therefore, other coins with a size larger than 500 yen coins, etc.
It is excluded because it does not enter 1. However, not only the 500-yen coins but also other coins smaller in size than the 500-yen coins, and the fake coins of the same size as the 500-yen coins but made of magnetic material, Although the coins are thrown in, they are sorted from genuine coins of 500 yen by the mechanism of the main part of the coin sorting device of this example described below.

It should be noted that it is the same size as a 500 yen coin,
Even if the fake coin is made of a non-magnetic material, if the weight is lighter than the 500-yen coin, the merchandise providing mechanism does not start and the button 22 does not pop out. Can not.

FIG. 1 is a side view of a main part of a coin sorting device according to the present invention, and FIG. 2 is a front view thereof. A non-magnetic material, plastic in this example, is used for parts other than permanent magnets described later. ing. Further, FIG. 3 is a sectional view of a portion A of FIG.
4 is a sectional view of a B portion of FIG. 1, FIG. 5 is a sectional view of a C portion of FIG. 1, FIG. 6 is a sectional view of a D portion of FIG. 1, and FIG. 7 is a sectional view of an E portion of FIG. Here, the cross-sectional views of the A to E portions mean the views of the cross sections at the positions indicated by the arrows from the directions of A to E, respectively. The same applies to the following description.

In these figures, reference numeral 31 denotes a coin passage having a predetermined length, which is a coin or the like 30 inserted from the coin insertion slot 21.
Lands on this coin passage 31. This coin passage 31
Is the thickness t of the 500-yen coin, as shown in FIGS.
A passage having a larger width t1, for example, t1 = 4 mm, and having a predetermined inclination so that coins and the like descend and move on the passage 31 due to rotation or the like in the housing of the vending machine. It is said that.

Guide walls 32 and 33 are formed along both sides of the coin passage 31 in the width direction. These guide walls 32 and 33 serve as guides when a coin or the like inserted from the coin insertion port 21 moves on the passage 31. The lowermost tip of the coin passage 31 closes the space between the guide walls 32 and 33 with a wall 34 so that the coins will not drop further.

In this example, the guide wall 32 is provided almost vertically in the housing of the vending machine, but the guide wall 33 has a predetermined angle with respect to the vertical direction, for example, 30 degrees. It is formed with an inclination. And
The upper surface of the coin passage 31 is formed to be perpendicular to the guide wall 33. That is, the coin passage 31 is also inclined in the width direction as shown in the vinegar 2. Therefore, coins and the like inserted from the coin insertion port 21 are rotated and moved on the coin passage 31 along the guide wall 33.

A first opening 35 is formed in the middle of the coin passage 31 of the guide wall 33, as shown in FIGS. 1, 4 and 6. This first opening 35 is
In this example, it is formed in a rectangular shape, and as shown in FIG. 4, the upper surface of the coin passage 31 and the side 35 u of the upper end of the opening 35.
Are parallel to each other, and the distance r3 between the upper surfaces of the coin passages 31 and the upper end side 35u of the first opening 35 is r3.
Is a value slightly smaller than the diameter R (26.5 mm) of the 500-yen coin, and in this example, r3 = 26 mm.
In this example, the lower side 35d of the opening 35 is slightly higher than the upper surface of the coin passage 31 by, for example, 1 mm.

Therefore, among the coins and the like inserted from the coin insertion port 21, other coins having a diameter of 0.5 mm or more and smaller than the 500-yen coin are placed on the guide passage 3 on the coin passage 31.
When passing through the portion of the first opening 35 when moving downward along 3, the first opening 35 rotates and drops to the outside of the guide wall 33 as shown by the alternate long and short dash line in FIG. As a result, other coins and the like smaller than the 500 yen coin can be selected.

In this case, as shown in FIG. 1, FIG. 2, FIG. 6 and FIG. 7, when viewed from the coin insertion opening 21, the coin passage 31 is located in front of the first opening 35, and the guide wall 32 does not extend from the guide wall 32. ,
The movement path regulation plate 36 is provided so as to project toward the guide wall 32. The movement path regulation plate 36 has a triangular shape, and the guide wall 33 and the tip of the movement path regulation plate 36 form a gap 37 through which a coin or the like can pass. By this movement path regulation plate 36, coins and the like that have been inserted from the coin insertion port 21 always pass through the gap 37, and therefore, coins and the like always move along the guide wall 33 on the coin passage 31. To move. Therefore, the first opening 35 can reliably sort other coins or the like having a small size.

Further, as shown in FIGS. 1 and 3, the second opening 3 is formed in the guide wall 33 at the position of the coin passage 31 preceding the first opening 35 as viewed from the coin insertion opening 21.
8 is worn. The second opening 38 is also formed in a rectangular shape in this example, and the side 38d at the lower end of the second opening 38 is flush with the upper surface of the coin passage 31. In this way, the upper surface of the coin passage 31 and the second
Since the lower end side 38d of the opening 38 of the coin is flush with the side 38d, the coin passage 3 is not sorted by the first opening 35.
The coins and the like that have moved down along the guide wall 33 along the guide wall 33 to the portion of the second opening 38 are outside the guide wall 33 from the second opening 38 as shown by the one-dot chain line in FIG. Slide down to.

In this example, the upper surface of the coin passage 31 and the side 38u of the upper end of the second opening 38 are parallel to each other. However, the upper surface of the coin passage 31 and the upper end of the second opening 38 are parallel to each other. The distance r4 with respect to the side 38u may be large enough for a coin or the like to slide down to the outside of the guide wall 33, and in this example, r4 = 23 mm.

As shown in FIG. 1, in this example, other coins or the like having a size smaller than 500 yen coins dropped from the first opening 35 are guided to the small-sized coin orbit 41, and the second coin. 500-yen coins and 5 slipped from the opening 38
A coin or the like having the same size as the 00 yen coin is guided to the material selection track 42.

The tracks 41 and 42 are composed of wall plate portions 51 and 52 facing each other with a predetermined space and a partition portion 53.

That is, as shown in FIG. 2, the guide wall 3
The outer side of 3 is a wall plate portion 51 having a width that is parallel to the guide wall 32 and includes a portion of the first opening 35 and the second opening 38 in the direction along the coin passage 31. The wall plate portion 51 extends downward from the positions of the openings 35 and 38. A wall plate portion 52 is formed at a predetermined distance from the wall plate portion 51. As described above, the wall plate portion 51 and the wall plate portion 52 form a coin orbit that descends from the first and second openings 35 and 38, and the wall plate portion 51 and the wall plate portion 52. The interval between and is equal to or slightly larger than the dimension w0 of the coin insertion port 21 that regulates the thickness of the inserted coin or the like.

The wall plate portions 51 and 52 are connected to each other at their ends in the width direction (left and right direction in the drawing). Further, the wall plate portion 52 is connected to a portion forming the coin passage 31 in the portion of the first and second openings 35 and 38 via a predetermined curved surface portion 52a, as shown in FIGS. ing.

As shown in FIG. 4, in this example, the distance L between the guide wall 32 and the wall plate portion 51 is, as shown in the figure, the diameter R of the coins or the like so that the coins or the like can rotate. It is selected to be larger, and in the case of this example, the first opening 3
5 is equal to the distance between the upper side 35u and the coin passage 31 and L =
It is set to 26 mm.

The partition portion 53 is provided in the space between the wall plate portion 51 and the wall plate portion 52 in a wedge shape downward from the portion of the kerf of the first opening 35 and the second opening 38. With the partition 53, the wall plate portion 51 and the wall plate portion 52 are
In the space between and, the part connected to the first opening 35 is the small coin track 41, and the part connected to the second opening 38 is the material selection track 42.

The small-sized coin orbit 41 is in communication with the return orbit 43, and the material selection orbit 42 is in communication with the true coin orbit 44. As shown in FIG. 1, the return track 43 and the true coin track 44 are bifurcated so as to be independent trajectories. Has been done. A permanent magnet 60 is provided on the wedge-shaped partition portion 53 above the confluence portion 45. The permanent magnet 60 is provided for selecting a 500-yen coin made of a non-magnetic material and a false coin made of a magnetic material.

As shown in FIG. 5, the permanent magnet 60 of this example has a flat disc shape, is sandwiched between the wall plate portions 51 and 52, and is surrounded by a wedge-shaped partition portion 53. And fixed in the position shown. In this case, the entire circumference of the disk-shaped permanent magnet 60 is not surrounded, but the portion facing the material selection track 42 side and the merging portion 45 is exposed.

As described above, only a part of the periphery of the disk-shaped permanent magnet 60 is exposed to the orbit 42 so that when the entire circumference of the magnet 60 is exposed, a false coin or the like made of a magnetic substance is exposed. The permanent magnet 60 is prevented from being removed while being attracted to the permanent magnet 60, and is prevented from being returned to the return port, and when a false coin is attracted next and is then inserted from the coin insertion port 21, a false coin or the like is generated. This is to prevent a malfunction that would be dropped on the true coin orbit.

Further, in this example, a claw portion 61 for surely separating the pseudo coin or the like of the magnetic material attracted to the permanent magnet 60 from the permanent magnet 60 is provided at the confluence portion 45 or the return track 43. It is provided for the peripheral portion of the facing permanent magnet 60.

The claw portion 61 is, in this example, the partition portion 5.
Of the portion covering the permanent magnet 60 at 3, the tip portion of the portion located on the merging portion 45 side is formed. Instead of configuring the claw portion 61 as a part of the partition portion 53, the partition portion 5
Of course, it is also possible to provide the claw portion 61 independently of 3.

The function and effect of the claw portion 61 will be described with reference to FIG. The pseudo coin Cn of the magnetic material that has descended the material selection track 42 is attracted to the permanent magnet 60. Then, while being attracted to the permanent magnet 60, the pseudo coin Cn of the magnetic material is
Etc. rotate around the periphery of the permanent magnet 60, and the claws 6
When it comes to the 1st part, because of the inertial force of its own rotation,
The fake coin Cn or the like is in a state of riding on the claw portion 61 or strongly colliding with the claw portion 61. Therefore, the false coin Cn and the like are separated from the permanent magnet 60 at the position of the claw portion 61.

The angular range α (see FIG. 9) of the exposed peripheral side surface of the permanent magnet 60 is determined according to the size of the permanent magnet 60 and the magnitude of its magnetomotive force. In this case, the magnetomotive force of the permanent magnet 60 may be any that is capable of attracting a false coin or the like made of a magnetic material that falls from the material selection orbit 42 and guiding it to the return orbit 43, and is from 500 to 3000.
Gaussian ones can be used. In this example, it is a disc shape with a diameter of 15 mm and a thickness of 4.8 mm.
A 00 Gauss permanent magnet is used.

In this example, the position of the tip 46 of the V-shaped branch portion that divides the true coin orbit 44 and the return orbit 43 is slightly displaced to the material selection orbit 42 side, and the permanent magnet 60 is used. Thus, it is possible to reliably guide the false coin or the like made of the magnetic material to the extension portion of the return track 43. Fifty
The 0-yen coin hits the tip 46, but since the center of gravity of the coin is on the true coin orbit 44 side, the 500-yen coin bounces to the true coin orbit 44 side and is guided to the true coin orbit 44 side.

The tip of the true coin orbit 44 is an opening, and although not shown, the above-mentioned product discharging mechanism which is activated by the weight of, for example, 500 yen coins is installed at the tip of this opening. In addition, a box-shaped portion 47 having an opening that serves as a return port 23 for coins or the like is provided at the tip of the return track 43.

With the above-mentioned structure, as described above, the 500-yen coin inserted from the coin insertion slot 21 and other coins of a smaller size are rotated on the coin passage 31. While descending. During this descent, coins and the like are transferred to the guide wall 3 by the movement path regulation plate 38.
The movement path is regulated so as to rotate and descend along 3.
Then, when passing through the portion of the first opening 35 of the guide wall 33, another coin or the like having a size smaller than the 500-yen coin falls from the first opening 35 into the small-sized coin orbit 41, and the return orbit 43. Through the box-shaped portion 47. In other words, other coins with a size smaller than 500 yen coins,
It is returned to the return port 23.

A 500-yen coin and a fake coin having the same size as the 500-yen coin pass through the first opening 35, but fall from the second opening 38 onto the material selection track 42. Then, the fake coin or the like made of a magnetic material is attracted or attracted to the permanent magnet 60, and the adsorbed fake coin or the like is guided from the claw portion 61 to the return track 43 side and becomes the return port 23. Fall into 47.

Since the 500-yen coin is a non-magnetic material, it is not attracted by the permanent magnet 60, and the position where the starting portion of the product discharging device is actuated via the true coin orbit 44 connected to the material selection orbit 42. To fall.

In the above example, the first opening 35 causes 50
For coins smaller than 0 yen coins, the coin passage 31
Since it rotates in a tumble manner with the fulcrum as a fulcrum, the distance from the coin passage 31 to the wall plate portion 51 is equal to the height of the opening 35,
In this example, 26 mm is required, which makes the coin sorting device relatively thick.

FIGS. 10 to 17 show a second modified version of this point.
It is an example of.

FIG. 10 is a side view of an essential part of the coin sorting apparatus of the second embodiment, and FIG. 11 is a front view thereof. A portion excluding the permanent magnet 60 is a non-magnetic material, in this example, plastic. Is used. 12 is a sectional view of the F portion of FIG. 10, FIG. 13 is a sectional view of the G portion of FIG. 10, FIG. 14 is a sectional view of the H portion of FIG. 10, and FIG. 15 is a sectional view of the I portion of FIG. 16 is a sectional view taken along the J section in FIG. 10, and FIG. 17 is a partial view seen from the arrow K direction in FIG.

In the second embodiment, the coin passage 31 having a predetermined length and the guide walls 32 and 33 formed along both sides of the coin passage 31 in the width direction are formed in the first embodiment. It is similar to the embodiment. Further, the guide wall 33 has a first
The opening 35 is provided in the same manner as in the above example.

However, in the case of this example, the guide wall 33
A wall plate portion 71 is provided in parallel with the small size selection track 7
2 The small size selection track 72 communicates with the return track 43 as shown in FIG. In the case of this example, the wall plate portion 71 forming the small size selection track 72 is shown in FIG.
As shown in FIG. 11, it is independent, and only this small size selection track 72 projects outward as shown in FIG.

Further, as shown in FIGS. 10 and 15, a part 35f of the lower end side 35d of the first opening 35 in this example is flush with the coin passage 31 and is smaller than a 500-yen coin. Other coins of a different size, etc. are changed from the part 35f to the small size selection track 72 between the coin passage 31 and the wall plate portion 71 and the guide wall 33, and are guided to the return track 43. Get burned.

Further, in this example, the second opening 38 is not formed in the guide wall 33, and instead the second opening 38 shown in FIG.
As shown in FIG. 3 and FIG. 17, the coin passage 31 in the portion corresponding to the portion in which the second opening 38 of the above-mentioned example is formed disappears to become the opening 73. Therefore, the 500-yen coins and other coins of the same size, which are not sorted by the first opening 35 so as to be guided to the return orbit, are stored in the opening 7
Immediately fall from 3 to the material selection track 42.

At the confluence portion 45 of the return track 43 and the material selection track 42, there is provided a permanent magnet 60 for selecting a fake coin made of a magnetic material and a 500-yen coin made of a non-magnetic material. The other points are almost the same as in the first embodiment.

Also in the case of the second embodiment, a method of forming a track after selecting a 500-yen coin and a coin of the same size, and another coin having a size smaller than the 500-yen coin is Except for the difference from the first embodiment, the same operational effect as the first embodiment can be obtained.

In the above embodiment, the material selection track 4
Of the coins falling from 2, the true coin of the 500 yen coin is
Since the tip ends 46 of the forked portions of the return track 43 and the true coin track 44 collide with each other, there is a slight risk of falling to the return track 43 side. An example of a method of preventing this and surely guiding the 500-yen coin to the true coin orbit 44 side will be described.

In this method, as shown in FIGS. 18A and 18B, a coin such as a 500-yen coin usually has a peripheral edge portion of 18 coins.
a utilizes the point that the thickness is slightly thicker than the inside 18b.

FIG. 19 and FIG. 20 are examples of the configuration of the main part thereof. That is, in this example, as shown in FIG. 20, the wall plate portion 51 at a position on the side of the true coin orbit 44 in the vicinity of the confluence portion 45 and at a position on the left side of the center portion of the orbit 42 or 44. At a predetermined position of 52, a hooking protrusion 81 that elastically protrudes into the orbital space of the coin in the wall plate portions 51, 52,
82 is provided. The hooking protrusions 81 and 82 are housed in small chambers 83 and 84 provided in the wall plate portions 51 and 52, and are always biased toward the orbital side of the coin by springs 85 and 86.

Therefore, when the 500-yen coin drops from the material selection track 42 to the merging portion 45, the hooking projections 81 and 82 are once pushed back into the small chambers 83 and 84 by the peripheral edge portion 18a. , When it comes to the concave portion of the inside 18b of the 500-yen coin, the hooking protrusion 81,
82 pops out due to the biasing force of the springs 85 and 86,
It comes into contact with the inside 18b of the yen coin. Then, when the coin further drops and reaches the position of the peripheral edge portion 18a again, this peripheral edge portion 18a is caught by the hooking projections 81 and 82, so that the 500-yen coin is pulled toward the true coin orbit 44 side. To fall.

On the other hand, the peripheral edge 18a is not thicker than the inside 18b like a 500-yen coin, and the hooking projections 81 and 82 do not serve flat coins or the like. However, it is not forcibly guided to the true coin orbit 44.

In the above example, the coins are 500-yen coins, but the present invention is applicable to the selection of 100-yen coins and coins of different size from other coins. .

[0071]

As described above, according to the present invention, other coins or the like having a size larger than the coin to be sorted cannot be inserted from the coin slot, so that coins having a size larger than the coin to be sorted cannot be inserted. Coins, etc. are selected at the time of this insertion.

Then, among the coins inserted from the coin slot, other coins having a size smaller than that of the coin to be sorted are guided from the first opening to the first coin orbit, which is a return orbit, for example. It is burned and sorted. At this time, when the movement path regulation plate is installed between the coin insertion slot and the first opening, the coins and the like always take a movement path that is biased toward the first opening side, so Other small-sized coins and the like are reliably guided to the first coin orbit from the first opening.

When the second coin orbit guided by the second opening is a material selection orbit, the same coins as the objects to be selected are selected by the material selection means having a permanent magnet provided in the material selection orbit. When the other coin or the like having a size is a magnetic body, the other coin or the like is attracted by the permanent magnet and guided to the return track.

In the case of creating a fake coin having the same size and weight as the selected coin, considering the distribution price value of the coin and the production cost, inexpensive iron or the like, which is a magnetic material, is used as the material. Considering that it is considered that most of them are used, according to the present invention, the fake coin or the like made of a magnetic material is surely selected by the material selecting means using the permanent magnet and is guided to the return track. It will be
