Description

The present invention relates to a token transfer body that transfers a token of a token image acquisition device that acquires an image of a token with an imaging device.
In particular, the present invention relates to a token transfer body that does not affect imaging of a token that moves at high speed, and prevents a transferred token from entering a gap with the token transfer body.
The “token” used in this specification includes coins and substitute coins such as medals, and the shape includes a circle and a polygon.

  The present applicant captures a token that moves while sliding on the base with the imaging device, and in the token image acquisition device configured to acquire imaging information, the pusher that moves at a predetermined speed, and the pusher A token image acquisition device comprising: a guide body that guides a token to be moved; an imaging device that images a token that is pushed by the pusher; and an alignment supply device that supplies the pusher with tokens one by one; In addition, a token sorting device that includes this token image obtaining device and sorts a genuine token or a false token by comparing an image captured by the image obtaining device with a reference image has been proposed (for example, see Patent Document 1).

JP2007-219804 (FIGS. 1 to 6, paragraph numbers 0005 to 0053)

According to the present invention, since the token is imaged while actively pushing the token with the pusher, there is an advantage that it is difficult to cause a deviation of the imaging timing, and authenticity determination or selection can be performed with high speed and high accuracy.
In order to obtain a clear image of the fast moving token, the token is performed under a large amount of light.
In addition, the members near the imaging position are arranged so as not to be positioned closer to the imaging device than the upper surface of the token so that the imaging surface of the token is not behind the constituent members.
For this reason, there is a problem that a token enters between the pusher and the token passage determining member and the transfer body rarely rotates.
This problem will be described in detail with reference to FIG.

The token T slides on the slide base 2 by being pushed by the edge of the pusher 4 of the token transfer body 3.
The edge portion 6 of the pusher 4 is formed thinner than the central portion 8, and is formed in a convex shape with the center raised.
The imaging device 10 is disposed relative to the slide base 2.
The imaging device 10 includes an imaging element 12, a lens 14, and a light 16 for token projection.
The light 16 is arranged in a ring shape so that a large number of light emitters surround the outer periphery of the lens 14.
In order to protect the lens 14, a passage defining plate 18 that defines the passage of the token T, for example, a transparent glass plate 20, is disposed with respect to the slide base 2 at an interval of not more than twice the maximum token thickness.
The upper surface of the edge 6 of the pusher 4 is set to be equal to or less than the token upper surface even with the thinnest token thickness.
Since the token T has various thicknesses, the interval between the slide base 2 and the glass plate 20 is set so that all tokens can be selected.
In other words, the thickness of the passage is an interval at which the two thickest tokens T do not overlap.
As a result, when the thinnest token is used, an interval equal to or larger than the thickness of the token T is formed between the upper surface of the thin edge portion 6 and the glass plate 20.
Even if the token is not the thinnest token, the token T can enter between the edge 6 and the glass plate 20 when the pusher 4 is bent.
When the token T bounces, there is a rare problem that the end of the token T enters between the edge 6 of the pusher 4 and the glass plate 20, and the pusher 4 cannot rotate.
In this case, after the overload is detected by the built-in overload detector and the rotation of the pusher 4 is stopped, the glass sheet 20 is removed and the inserted token T must be removed, which is complicated.

A first object of the present invention is to provide a token transfer body for a token image acquisition device in which a token does not enter between a pusher and a passage defining plate.
A second object of the present invention is to provide a token transfer body in which no token enters between the pusher and the passage defining plate and does not affect imaging for the token image acquisition device.
A third object of the present invention is to provide a token transfer body for a token image acquisition device in which a token does not enter between a pusher and a passage defining plate at a low cost.

In order to achieve this object, the invention according to claim 1 is configured as follows.
That is, the invention of claim 1 accepts tokens one by one in the recesses formed between the plurality of pushing bodies extending in the circumferential direction of the token transfer body disposed in the circular hole and having the outer peripheral side opened, In the token image acquisition device, the image is picked up by the image pickup device that is arranged relative to the movement path of the token that moves while being guided by the peripheral surface of the circular hole by sliding on the base, and acquiring the image pickup information of the token The token transfer body is thinner than the token, and the peripheral edge of the recess is formed thinner than the central portion of the pusher, and is disposed at a position farther from the imaging device than the imaging surface of the token. A token transfer body for a token image acquisition device, wherein a thin rib that rises toward the image pickup device is formed in the thin portion.

According to a first preferred embodiment of the present invention, in the token transfer body for a token image acquisition device according to claim 1, the tip of the rib is formed in a cylindrical shape.

According to a second preferred embodiment of the present invention, in the token transfer body for a token image acquisition device according to claim 1, the rib is disposed to face the end of the recess and the bottom of the recess.

In this configuration, the token is pushed by the rotating pusher and is rotated while being guided by the inner peripheral surface of the circular hole.
Specifically, the token slides on the slide base in the recess formed between the pushers while being held in the recess by the front edge of the pusher, the bottom edge of the recess, and the rear edge of the pusher.
In this sliding process, one side of the token is imaged.
The peripheral edge of the pusher is formed thin, and one surface thereof is located farther from the imaging device than the thinnest token.
Although the rib is formed in the thin portion, since it is narrow, one surface of the token is not substantially hidden.
Therefore, the projection light that projects one side of the token when the token is imaged is not blocked.
Microscopically, the token slides while bouncing against the slide base.
For this reason, when selecting the thinnest token, the token tries to enter between the thin portion and the passage defining means, but is blocked by the thin portion rib and cannot enter.
In other words, since the thickness between the rib and the passage defining means is narrower than the thickness of the thinnest token, the token does not enter.

In the first preferred embodiment , the tip of the rib is formed in a cylindrical shape.
In the case of the cylindrical shape, since the range that blocks the projection light is small, there is an advantage that the strength of the thin portion can be improved and the entry of the token can be prevented.

In a second preferred embodiment , the rib is disposed opposite the end of the recess and the bottom of the recess.
There is an advantage that it is possible to reliably prevent the token from entering the thin portion by the ribs arranged at three positions around the recess.

  The tokens are received one by one in a recess formed between a plurality of pushers extending in the circumferential direction of the token transfer body arranged in the circular hole and the outer peripheral side is opened, and the circular hole is slid on the base of the circular hole. In the token image acquisition device, the token transfer body is configured to acquire the imaging information of the token by imaging with an imaging device disposed relative to a movement path of the token moving while being guided by the peripheral surface of the token. It is thinner than the thickness, and the peripheral edge of the concave portion is formed thinner than the central portion of the pusher, and is disposed at a position farther from the imaging device than the imaging surface of the token, and the thin portion is closer to the imaging device side. A narrow-width rib that rises toward the bottom, the rib being disposed opposite to the end of the recess and the bottom of the recess, and the tip of the rib being formed in a cylindrical shape. A token image acquiring apparatus token transfer body to symptoms.

  The token sorting device 102 including the token image acquisition device 100 captures the pattern of the surface of a large number of tokens 104 by the imaging device 106 and acquires it as image information, determines authenticity based on the image information, and determines the determination result. Based on this, the distribution device 108 has a function of selecting a genuine token or a false token.

First, the token image acquisition device 100 will be described.
The token image acquisition device 100 has a function of capturing images by the imaging device 106 in the process of actively pushing the tokens 104 stacked one by one and then actively pushing them by a pushing edge 166 described later.
Token image acquiring apparatus 100 to push at least a bulk body token one by one division to aligning and supplying apparatus for supplying a next step 110, the token 104 one by one divided by the aligning and supplying apparatus 110 press A moving device 112 and an imaging device 106 are included.

Next, the alignment supply device 110 will be described.
The alignment supply device 110 has a function of sorting the tokens 104 in a loose state one by one and sending them to the next imaging process.
Therefore, the alignment supply device 110 can be changed to another device having the same function.
The alignment supply device 110 according to the present embodiment has a function of dividing the tokens 104 in a loose state one by one and sending them to the pushing device 112 in the next stroke. And a delivery device 122 located in the lower part.
The holding bowl 120 has a vertically-oriented cylindrical shape as a whole, the upper part is substantially rectangular, has a receiving opening 124 at the upper end, and a circular hole 126 is formed at the lower end.
The holding bowl 120 has a function of holding a large number of tokens 104 in a stacked state, and is detachably attached to the upper surface of a guide body 128 described later.

Next, the delivery device 122 will be described.
The sending device 122 has a function of sorting and sending the tokens 104 held in the holding bowl 120 one by one.
Therefore, the delivery device 122 can be changed to another device having the same function.
The delivery device 122 in this embodiment is a rotating disk 132 having a plurality of through holes 130 having a diameter slightly larger than the diameter of the token 104.

The rotating disk 132 is disposed in a first circular recess 138 formed in a guide body 128 that is disposed on a base 136 that is an upper surface of a box-shaped base 134 below the storage bowl 120, and is fixed to the base 136. The electric motor 140 rotates counterclockwise in FIG. 3 via the transmission mechanism 142 and the first rotating shaft 144.
The rotating disk 132 has a mountain-shaped stirring portion 146 in the center, and is disposed concentrically with the circular hole 126 of the storage bowl 120 in the first circular recess 138 of the guide body 128.
The rotating disk 132 has an extrusion protrusion 148 on the back surface of the rib between the through holes 130.
Token 104 that has dropped into the through hole 130, supported by the base 136 of the first circular recess 138, and, by the movement of the extrusion ridge 148 by the rotation of the rotating disk 132 while being guided by the peripheral surface of the first circular recess 138 It is pushed and moves with the rotating disk 132.
The token 104 to be moved protrudes from the base 136 and is guided in the circumferential direction of the rotating disk 132 by the restriction pins 150 and 152 located in the movement path of the token 104.
The tokens 104 guided in the circumferential direction are sent to the pushing device 112 one by one through the communication path 154.
The roller 156 arranged adjacent to the side of the rotating disk 132 can elastically rotate around the rotating disk 132 in the counterclockwise direction in FIG.

The roller 156 is disposed adjacent to the rotating disk 132, and has a function of buffering the impact and guiding it to the pushing device 112 side when the delivered token 104 collides.
Therefore, the roller 156 can also be fixed.

Next, the base 136 will be described with reference to FIG.
The base 136 has a function of guiding the lower surface of the token 104 while sliding.
In the present embodiment, the base 136 includes an imaging unit base 158 and other part base 160.
However, the base 136 can be constituted by a single plate-shaped member by an imaging unit base 158 and the same material.
In this embodiment, the other part base 160 is treated with an iron nitride compound layer on the surface of the stainless steel plate to improve the wear resistance and the surface is textured.
A roughly rectangular opening 162 is formed in a portion of the other part base 160 facing the imaging device 106.

The imaging unit base 158 is formed of a dark base resin into a shape that fits closely into the opening 162.
The dark color means black, dark gray, dark brown, dark blue, etc., and means low reflectance color and lightness.
For example, a polyacetal resin is adopted as the base resin in consideration of wear resistance.
In this embodiment, a carbon powder is mixed with a polyacetal resin as a base material, and a black base resin is used.
Thereby, since base resin is black, the reflectance of the light by a color and brightness is the smallest.
However, the same effect can be obtained by using a dark dark color close to black.
And since resin has a uniform coloring degree from the surface to the inside, even if base-material resin is worn out, the surface is the same black and brightness.

Further, since the token 104 receives mechanical pressure or collides with a metal part in a game machine or the like, the surface is not smooth when viewed microscopically.
As a result, when the token 104 slides on the imaging unit base 158, the resin base material of the imaging unit base 158 is lower in hardness than the token 104, and is thus damaged by the token 104, and the surface is not mirror-like, and is rough. is there.
Thereby, the projection light for imaging is irregularly reflected by the rough surface, and the lightness does not change, so that the low reflectance is maintained.
As described above, by using the dark color resin for the imaging unit base 158, it is possible to maintain the same brightness and reflectivity as the original even if the slide surface is worn.

The imaging unit base 158 is sandwiched and fixed between the base 134 by the guide body 128.
When the imaging unit base 158 is worn, damaged, or has a large scratch that interferes with imaging, the imaging unit base 158 can be replaced with another imaging unit base 158 .
Since this exchange can be performed by removing the guide body 128, the exchange work is easy.

Next, the pushing device 112 will be described with reference to FIG.
The pushing device 112 has a function of actively pushing the tokens 104 sent one by one from the sending device 122 one by one in a predetermined direction.
Therefore, the pushing device 112 can be changed to another device having a similar function.
In this embodiment, the pushing device 112 includes a peripheral edge 165 and a guide body 128.
The peripheral edge 165 includes a pushing edge 166 and a rear edge 167.

First, the pushing edge portion 166 will be described.
The pushing edge portion 166 has a function of moving in a predetermined direction at a predetermined speed and forcibly pushing the tokens 104 sent one by one from the alignment supply device 110 one by one.
In this embodiment, the pushing edge 166 is the front end in the rotational direction of the three-propeller shaped pushing bodies 168A, 168B, 168C formed on the token transfer body 170.
The token transfer body 170 is fixed to the tip of the second rotating shaft 172.
The second rotary shaft 172 to rotate in the clockwise direction in FIG. 3 in synchronism with the rotating disk 132 is rotated from the transmission mechanism 142 of the rotation disk 132 via the second transmission unit 17 3.
In other words, the pushers 168A, 168B, and 168C revolve on a rotation path 175 that exists in a plane parallel to the base 136 positioned immediately above the base 136.
The upper surfaces 176 of the pushing edge portions 166 of these pushers 168A, 168B, and 168C are arranged not to be positioned above the upper surface of the thinnest token 104.

In addition, receiving recesses 177A, 177B, and 177C of the semicircular token 104 whose peripheral side is released are formed between the pushers 168A, 168B, and 168C.
These receiving recesses 177A, 177B, and 177C are formed slightly larger than the maximum diameter token 104 that is assumed to be used.
With this configuration, the tokens 104 received one by one in the receiving recesses 177A, 177B, 177C, the pushing edge 166, the pushing bodies 168A, 168B, 168C on the front side in the rotation direction, and the arcuate guide described later. It moves in the clockwise direction while colliding with the surface 182 and being guided.

In this embodiment, the pushing edges 166 and the rear edge 167 of the pushing bodies 168A, 166B, and 168C are thinner than the token 104, and the top surface of the token 104 that slides on the imaging unit base 158 ( It turns in a plane closer to the imaging unit base 158 than the imaging plane.
The reason is that projection light from a light projecting device 192, which will be described later, is blocked by the pushers 168A, 166B, and 168C and the imaging surface of the token 104 is not hidden.
As shown in FIG. 10, the cross sections of the pushers 168A, 168B, and 168C are formed such that the central portion 174 is thicker than the pusher edge 166 and the rear edge 167, and extends to the tips of the pushers 168A, 168B, and 168C. And the strength is secured.

The pushing edge portion 166 and the rear edge portion 167 are thinned following the center portion 174 so that the strength of the pushing bodies 168A, 168B, and 168C is maintained and the imaging surface of the token 104 is not shaded by the pushing body. ing.
The central portion 174 can be disposed at a position farther from the imaging unit base 158 than the upper surface of the token 104.
Ribs 180A, 180B, and 180C for preventing entry of tokens are formed on the upper surface 176 of the pushing edge 166 and the rear edge 167 of each of the pushing bodies 168A, 168B, and 168C.
Since the positions of the ribs 180A, 180B, and 180C in the pushers 168A, 168B, and 168C are the same, the pusher 168A will be described as a representative.

The rib 180A is formed in an arc shape centering on the rotational axis of the token transfer body 170 on the upper surface 176 of the pushing edge 166 at the tip of the pushing body 168A.
The tip of the rib 180A is formed in a cylindrical shape, and is flush with the tip of the push edge 166.
The rib 180B extends radially from a position slightly deviated from the rotation center of the token transfer body 170, and extends from the center portion 174 to the vicinity of the end of the bottom portion 179A of the receiving recess 177A from the upper surface 176 of the pushing edge portion 166, and the tip thereof It is formed in a cylindrical shape.
The tip of the rib 180B is slightly retracted from the edge in order to prevent the upper surface of the token 104 from being shaded by the projection light.
The rib 180C extends from the middle center part 174 of the pusher 168A to its end on the upper surface of the rear edge 167 , and its tip is formed in a cylindrical shape.
The interval between the ribs 180A, 180B, and 180C is at most about two-thirds of the diameter of the minimum diameter token 104.

This is to prevent the peripheral edge of the token 104 from climbing on the upper surface 176.
Pushed by the end face of the pressing edge 166 by the rotation of the token transfer Okukarada 170, the token 104 passes under the imaging device 106 while being guided its outer peripheral surface in an arc guide surface 182.
Normally, the token 104 moves along the arcuate guide surface 182 by centrifugal force.
However, the token 104 to be moved at high speed jumped by dust and the like are slight unevenness and adhesion of the imaging unit based 158, also by collision shocking by pressing edge 166, rear edge 167 and the receiving It moves while being guided by the bottom 179A of the recess 177A .
At this time, any attempt to enter between the upper surface 176 of the pushing edge 166 and the passage defining means 229 is blocked by the ribs 180A, 180B, 180C.
Therefore, the token 104 does not enter the passage defining means 229.

In this embodiment, the token transfer body 170 is formed of the same material as the imaging unit base 158.
In other words, it is integrally molded with a dark resin containing minute pieces 162.
Therefore, as described above, the surface of the token transfer body 170 has a satin-like shape, light is irregularly reflected, and since the lightness is low, the light reflectance is low and the overall light reflectance is low.
Therefore, the token transfer body 170 has no influence on the token imaging.

Next, the guide body 128 will be described with reference to FIGS.
The guide body 128 has a function of guiding the token 104 pushed by the pushing edge 166 or the like in a predetermined direction.
Therefore, it can be changed to another device having the same function.
In this embodiment, the guide member 128 is formed of a stainless steel plate, the second circular hole 178 in succession to the first circular hole 13 5 is formed.
The thickness of the guide body 128 is set in consideration of the thickness of the token 104.
That is, since the token 104 has a different thickness for each type, it is set to be equal to or greater than the thickness of the thickest token 104 and less than twice the thinnest token thickness in the token thickness types assumed to be used. .
This is to prevent the tokens 104 from overlapping and to restrict irregular movement of the tokens 104 that are moved at high speed.

The imaging device 106 is configured to be automatically positioned by assigning the bottom surface 230 (see FIG. 15) of the imaging device 106 to the upper surface of the guide body 128.
In other words, the focal length range of the imaging device 106 is set with respect to the upper surface of the token 104 that slides on the imaging unit base 158.
A partial circumferential surface of the second circular hole 178 is an arcuate guide surface 182 of the token 104.
The arcuate guide surface 182 is subjected to a hardening process such as forming the nitrided layer because the peripheral surface of the token 104 slides.

As shown in FIG. 3, a semicircular concave groove 181 is formed on the upper surface of the guide body 128 so as to be opposed to a part of the arcuate guide surface 182.
The recessed groove 181 has a height from the upper surface of the imaging unit base 158 that is approximately two-thirds of the token thickness, and is approximately the same height as the upper surface of the pushing edge 166 from the upper surface of the imaging unit base 158. is there.
The concave groove 181 is provided opposite to the image pickup device 106, and the surface thereof is treated with a satin finish like the image pickup unit base 158.
Accordingly, the projection light from the light projecting device 192 of the imaging device 106 reaches the upper surface of the concave groove 181 after passing through the upper surface of the token 104.
Therefore, since the upper surface of the token 104 is not hidden behind the guide body 128, the imaging of the token 104 is not affected.
The guide body 128 is formed so as to be divided into a portion facing the rotating disk 132, in other words, a portion surrounding the first circular recess 138 and the token transfer body 170, in other words, a constituent portion of the second circular hole 178, and the like. Can do.

The token transfer body 170 is disposed concentrically in the second circular hole 178 and is rotated in the clockwise direction in FIG.
As a result, the token 104 that has passed through the communication path 154 is immediately pushed by the pushing edge 166 of the token transfer body 170 and moved onto the image pickup unit base 158, and is roughly guided while being guided by the arcuate guide surface 182 on its peripheral surface. The direction is changed by 180 degrees and reaches an exit 326 described later.
The token 104 is determined to be authentic based on the imaging information obtained by the imaging device 106, and is guided to the genuine token exit 184 or the false token exit 186 by the distribution device 108.
A path along which the token 104 moves while being guided by the arcuate guide surface 182 while being pushed by the pushing edge 166 is an imaging path 188, and the imaging apparatus 106 is disposed facing the imaging path 188.
Specifically, the transparent plate 232, which will be described later, is arranged so that a part of the periphery is positioned above the groove 181.

Next, the imaging device 106 will be described with reference to FIG.
The imaging device 106 has a function of capturing an image of the token 104 moving on the imaging path 188 and acquiring image information.
Therefore, the imaging device 106 can be changed to another device having the same function.
Imaging device 106 in this embodiment is removably attached to the upper surface of the guide member 128 by the holding device 18 5.

First, an outline of the imaging device 106 will be described with reference to FIG.
The imaging device 106 is arranged so as to image the upper surface of the token 104 that slides on the imaging unit base 158.
However, the imaging device 106 can also be arranged to image the lower surface of the token 104.
The imaging device 106 includes at least a camera 190, a light projecting device 192, and a timing signal output device 194.

Next, the camera 190 will be described.
The camera 190 has a function of capturing an image of the face of the token 104 facing and acquiring image information of a pattern on the face.
In this embodiment, the camera 190 is, for example, a CCD camera, and there are a method using a shutter and a method not using a shutter, but any method can be used as long as the token 104 moving at high speed can be imaged.

Next, the light projector 192 will be described.
The light projecting device 192 has a function of projecting light onto the token 104 in a concentrated manner.
Since the light projecting device 192 captures a large number of tokens 104 that move at high speed, it is required to have high luminance and high durability. For example, it is preferable that the light projecting device 192 be configured to have a large number of white LEDs facing the token 104.

Next, the timing signal output device 194 of the imaging device 106 will be described.
The timing signal output device 194 has a function of outputting a timing signal for setting at least the imaging timing of the camera 190 and the light projection timing of the light projecting device 192 in conjunction with the moving token 104.
Therefore, the timing signal output device 194 can be changed to another device having the same function.
In this embodiment, the timing signal output device 194 outputs a timing signal by indirectly detecting the position of the pushing edge 166, but directly detects the position of the pushing edge 166, for example, a pushing body. The timing signal may be output by directly detecting the positions of 168A, 168B, and 168C.

The timing signal output device 194 of the present embodiment will be described with reference to FIG.
The timing signal output device 194 includes a disk 196 fixed to the second rotating shaft 172 of the token transfer body 170, a first timing sensor 198, a second timing sensor 200, and a timing signal output circuit 202.

The disc 1 96, pusher 168A, 168B, three reference holes 198A equiangularly in response to 168C, 198B and 198C is formed on the first concentric circle C1 around the second rotary shaft 172 Yes.
Further, between the reference through holes 198A, 198B, and 198C, the same number of split angle through holes 200A... Are formed on the second concentric circle C2.
The first timing sensor 198 is arranged so that the projection light from the light projecting unit 204 can pass through the reference through holes 198A, 198B, and 198C, and outputs the reference signal SS every time the light receiving unit 206 receives the light.
The second timing sensor 200 is arranged so that the projection light from the light projecting unit 208 can pass through the split angle through-holes 200A,..., And outputs a count signal CS every time the light receiving unit 210 receives the light.

The timing signal output circuit 202 receives the reference signal SS from the first timing sensor 198 and the signal CS from the second timing sensor 200, and outputs the light projection signal PS at a preset timing.
For example, when the reference signal SS from the first timing sensor 198 is received and the count signal CS from the second timing sensor 200 reaches a predetermined number, for example, 20, the light projection signal PS is output.

The timing signal output circuit 202 can also output the light projection signal PS after a predetermined time has elapsed after inputting a predetermined number of count signals CS.
Thus, by outputting the light projection signal PS based on the number of count signals CS, it is possible to output a timing signal for light projection with high accuracy.
The light projecting device 192 projects light using the light projection signal PS as a trigger.
This light projection timing is a timing suitable for imaging the entire upper surface of the token 104 that is pushed by the pushing edge 166.
In addition, the camera 190 performs imaging processing in synchronization with the light projection of the light projecting device 192.

Next, a device 212 for discriminating captured image information will be described with reference to FIG.
The determination device 212 has a function of converting an image captured by the imaging device 106 into image information and comparing the image information with reference image information to determine whether it is a genuine token or a false token.
Therefore, the determination device 212 can be changed to another means having the same function.
In this embodiment, the discrimination device 212 compares the image information from the image information device 214 that converts the image acquired from the imaging device 106 into image information, the image information from the image information device 214, and the reference image information stored in the reference image information device 216. The comparator 218 includes a discriminator 220 that discriminates the authenticity of the token 104 based on a signal from the comparator 218 and outputs a genuine token signal or a false token signal.

It will now be described with reference to FIGS. 15-17 the retaining device 18 5 of the imaging apparatus 106.
First, the positioning device 222 of the imaging device 106 will be described.
The positioning device 222 has a function of uniquely determining the imaging position of the imaging device 106.
The positioning device 222 includes an imaging side positioning structure 224 on the imaging device 106 side and a base side positioning structure 226 on the base 134 side.

First, the positioning structure 224 on the imaging side will be described.
The imaging device 106 has a main body 228 in which the above-described camera 190, light projecting device 192, and the like are built.
The main body 228 has a rectangular box shape as a whole, and the light projecting device 192 projects light for imaging through a circular transparent plate 232 made of glass or the like constituting a part of the bottom surface 230. Take an image.
The bottom surface 230 is planar, and positioning holes 238 and 240 into which cylindrical positioning pins 234 and 236 projecting from the outer guide body 128 on the concave groove 181 side of the guide body 128 are formed.
The passage defining means 233 is constituted by the bottom surface 230 and the transparent plate 232.
These positioning pins 234, 236 and positioning holes 238, 240 constitute a first positioning mechanism 242.
The positioning hole 238 is formed as an elongated hole and allows an accuracy error of the positioning pins 234 and 236.
A second positioning mechanism 244 is configured with respect to the first positioning mechanism 242 with a second circular hole 178 interposed therebetween.

The second positioning mechanism 244 is formed on a side wall 246 of the main body 228 on a cylindrical positioning pin 251 formed on the lower surface 250 of the triangular first held projection 248 and a positioning body 252 fixed on the upper surface of the guide body 128. It is composed of a circular fitting hole 254.
The positioning pin 251 can be fitted into the fitting hole 254 of the positioning body 252.

Next, the base side positioning structure 256 of the second positioning mechanism 244 will be described with reference to FIGS.
A rectangular rod-shaped positioning body 252 formed of, for example, polyacetal on the opposite upper surface across the second rotating shaft 172 with respect to the concave groove 181 of the guide body 128 moves the second circular hole 178 upward as shown in FIG. It is fixed to cover.
On the upper surface of the positioning body 252, a fitting portion 260 that is parallel to the upper surface of the guide body 128 is formed.
The guide side wall 262 rising upward from the assigning portion 260 is inclined so as to expand upward.
A circular fitting hole 254 into which the positioning pin 234 is fitted is formed in the middle of the assigning portion 260.
Further, the reference side wall 264 that is suspended with respect to the guide body 128 on the concave groove 181 side of the assigning portion 260 is parallel to a straight line 266 that connects the positioning pins 234 and 236.
The side wall 268 below the first held projection 248 in the main body 228 can come into surface contact with the reference side wall 264, and the positioning pin 251 fits into the fitting hole 254 in the surface contact state.

A flat passage cover 263 that covers the upper side of the token moving path downstream of the imaging path 188 is formed integrally with the positioning body 252.
The passage cover 263 and the imaging unit base 158 are parallel to each other and are arranged at an interval larger than the maximum thickness of the token 104 and less than twice the thinnest thickness.
The passage cover 263 preferably covers the movement path of the token 104 up to the position 265 of the dashed line in FIG.
This is to prevent exposure of the token transfer body 170 and stabilize the movement posture of the token 104.

When attaching the positioning device 222 to the base 134, first, the positioning pins 234, 236 of the first positioning mechanism 242 are inserted into the positioning holes 238, 240 in a state where the positioning pins 251 of the main body 228 are inserted into the fitting holes 254 of the positioning body 252. The position of the positioning body 252 inserted and placed on the guide body 128 is determined.
Next, the positioning body 252 is fixed to the upper surface of the guide body 128 by the screw 258.
If thereby the positioning of the imaging device 106, first the positioning pins 251 of the lower corner is dropped while Ategai the guide side wall 262 of the holding projections 248 while pressed against the reference side wall 264 of the lower side wall 268 of the body 228 is fitted into the fitting hole 254, in surface contact with the lower surface 250 Ategai portion 260 of the first held projections 248.

In this state, the body 228 is positioning the reference side walls 2 64, positioning pins 234, 236 projecting from the guide member 128 against the phase in the positioning holes 238 and 240 of the bottom surface 230 of the body 228 fits.
In this state, the transparent plate 232 on the bottom surface 230 is substantially parallel to the imaging unit base 158.
In other words, the top surface of the token 104 that slides on the imaging unit base 158 and the imaging device 106 are substantially parallel to each other, and the positional relationship in which the entire top surface of the token 104 can be positioned in the focal length range and imaging range of the camera 190 is configured. Is done.

In the present embodiment, the positioning device 222 that determines the position of the three points by the first positioning mechanism 242 and the second positioning mechanism 244 is employed. However, the mechanism for positioning at the two points employed in the first positioning mechanism 242 is employed. Can be adopted.
In other words, even if there are two points, the position of the imaging device 106 is uniquely determined.
Further, by combining the pin 236 and the fitting hole 240 of the first positioning mechanism 242 with the second positioning mechanism 244, positioning can be performed at two points.
However, the three-point positioning of the embodiment is more preferable because the positioning accuracy is increased.
Further, the positioning mechanism can be constituted by a member that restricts the side wall of the main body 228 at least at two points instead of the pin and the fitting hole of the embodiment.

Then the holding device 18 5 is described with reference to FIGS. 15 to 17.
Holding device 18 5 has a function of holding the position set body 228 by the positioning device 222.
In this embodiment, a one-touch type simple holding device 272 is employed to facilitate maintenance and inspection of the imaging device 106.
However, the holding device 18 5 may be a fixing means such as screws.

In this embodiment, the simple holding device 272 includes an operation lever 274, pressing bodies 276, 278 and pressed bodies 282, 284 for constituting a toggle mechanism.
The operation lever 274 has a portal shape, and both lower ends thereof are rotatably attached to a shaft 286 protruding from the base 134.
When the operation lever 274 does not hold the imaging device 106, the operation lever 274 is supported by the upper surface of the box 288 fixed to the base 134, and the position thereof is held.
When the operation lever 274 is in the holding position, the operation lever 274 is locked by the stoppers 29 3 and 294 fixed to the upper surface of the guide body 128 and is held almost vertically.

The pressers 276 and 278 are attached to the inside of the support columns 290 and 292 of the operation lever 274 so as to be rotatable around the shafts 29 5 and 296, and are attached to the later-described lock position by the biasing means 298 and 300. It is energized.
The urging means 298 and 300 are spring bodies 302 and 304 formed of a resin U-shaped thin plate integrally formed on the side surfaces of the pressing bodies 276 and 278, and the upper end portion is integrated with the operation lever 274. The turning force is applied by being locked to stoppers 306 and 308 formed on the surface.
When the pressing bodies 276 and 278 are not engaged with the pressed bodies 282 and 284, they are rotated by the urging force of the spring bodies 302 and 304, and are rotated clockwise with respect to the support columns 290 and 292 as shown in FIG. To be kept.

Semi-circular recesses 312 and 314 for engaging with the pressed bodies 282 and 284 are formed on the lower end surfaces of the pressing bodies 276 and 278, respectively.
Further, the pressers 276 and 278 are made of a slightly elastic material, for example, polyacetal resin.
The upper ends of the stoppers 306 and 308 of the operation lever 274 are bent at a right angle to form second stoppers 316 and 318 for the spring bodies 302 and 304.

Next, the pressed bodies 282 and 284 will be described.
The pressed body 282 is a semi-cylindrical portion formed at the apex of the first held protrusion 248.
On the side wall 320 of the first held projections 248 facing the side wall 246 which is provided, the second held projections 250 symmetrically with respect to the first held projections 248 (see FIG. 2) is formed, the semi-cylindrical portion at its top A pressed body 284 is formed.

Here, the center of the shaft 286 as shown in FIG. 16, the center of pressure point 322 and axis 294,29 5 between recesses 31 2, 31 4 of the top and the pressing body 276 of the presser 282 linear If located on L, distance between the center and the shaft 29 5, 2 9 6 axes 286 R is the top portion of the pressing body 282, 284 and shaft 286 (sites corresponding to pressure points) distance L1 and the axis 29 between 5 and 296 and slightly shorter than a length obtained by adding a distance L2 between the centers of the recesses 302 and 314 (portions corresponding to the pressure contacts).
In other words, there is a relationship of R <L1 + L2.

When the imaging device 106 is attached to the base 134, the operation lever 274 is brought down to the state shown in FIG.
Next, the imaging device 106 is positioned by the positioning device 222 (state shown in FIG. 2).
Next, the operation lever 274 is rotated counterclockwise from the state shown in FIG.
While the operation lever 274 is being rotated, the lower ends of the pressing bodies 276 and 278 constituting the recesses 3 1 2 and 3 14 are engaged with the side surfaces of the pressed bodies 282 and 284.
Further, when the operation lever 274 is rotated in the same direction, since the lower ends of the pressing bodies 276 and 278 are locked to the pressed bodies 282 and 284, the pressing bodies 276 and 278 use the shafts 29 5 and 296 as fulcrums. It rotates counterclockwise with respect to the columns 290 and 292.

Furthermore, when the operation lever 274 is rotated in the same direction, from the relation of R <L1 + L2, and the bottom of the recess 31 2, 31 4 of the top and the pressing body 276 of the presser 282 is pressed against.
In other words, the bottom surface 230 of the imaging apparatus 106 via the first held projections 248 and the second held projections 2 49 is pressed against the Ategai portion 260 of the top surface and positioning member 252 of the guide member 128.
When the centers of the pressure contacts 322, the shafts 286, and the shafts 29 5 and 296 at the tops of the pressed bodies 282 and 284 and the bottoms of the recesses 312 and 314 are positioned on the straight line L, the pressing force is maximized.
When the pressing bodies 276 and 278 do not have elasticity, the pressure contact 322 cannot be positioned on the straight line L.
However, in this embodiment, the pressing members 276 and 278 are formed of polyacetal resin and have elasticity, so that the pressure contact 322 can pass on the straight line L.
The struts 290 and 292 of the operation lever 274 are respectively locked by stoppers 29 3 and 294 protruding sideways from the base 134 at a position where the pressure contact 322 slightly passes the straight line L.

When the pressure contact 322 passes through the straight line L, a counterclockwise moment acts on the pressing bodies 276 and 278 around the axes 294 and 296 in FIG.
However, the pressing member 276, 278 is held in the position shown in FIG. 15 balanced with the spring force of the spring member 30 2, 30 4.
Therefore, the main body 228 of the imaging device 106 is pressed against and held by the guide body 128 and the fitting portion 260 by a pressing force based on R <L1 + L2-α (α is a decrease length of L2 due to the rotation of the pressing bodies 276 and 278). The

And to provide a large holding force to the imaging device 106 by to form a so-called toggle action mechanism, the holding device 18 5 In Example.
Since the pressers 276 and 278 receive a counterclockwise moment in FIG. 16, the operation lever 274 receives a counterclockwise moment in FIG. 16 via the shafts 284 and 286.
Accordingly, the operation lever 274 continues the holding position, so that the imaging device 106 is also held at the same position.

Next, the operation of the token image acquisition device 100 will be described.
The token 104 is held in the holding bowl 120 in a loose state.
Based on the activation signal, the electric motor 140 is operated and the imaging device 106 is also set in a standby state.
By first rotating shaft 144 via the reduction gear by the rotation of the electric motor 140 is rotated, the rotating disk 132 is rotated in the counterclockwise direction in FIGS.
At the same time, the second rotary shaft 172 through the thus second transmission device 17 3 to the reducer, thus a token conveying member 170 is rotated in the clockwise direction in FIG. 4 in synchronism with the rotating disk 132.

Due to the rotation of the rotating disk 132, the token 104 in the storage bowl 120 is stirred by the stirring unit 146 and the token 104 falls into the through hole 130.
The token 104 dropped into the through hole 130 is pushed by the pushing protrusion 148 on the lower surface of the rotating disk 132 while being guided by the lower surface on the upper surface of the base 136 and the peripheral surface on the inner peripheral surface of the first circular recess 138. At the same time, it rotates counterclockwise.

During this rotation process, the token 104 is guided in the circumferential direction of the rotary disk 132 by the restriction pin 150.
The token 104 guided in the circumferential direction moves to the second circular hole 178 through the communication path 154.
The token 104 reaches the rotation path 175 of the pushers 168A, 168B, and 168C in the second circular hole 178.
The token 104 that has reached the rotation path 175 is pushed by the pushing edge 166 that is the forward end of any of the pushing bodies 168A, 168B, and 168C and guided by the arcuate guide surface 182 of the second circular hole 178. The arcuate imaging path 188 moves while being moved.

In this moving process, the token 104 is moved along the arcuate guide surface 182 of the second circular hole 178 by the centrifugal force of the rotational movement.
However, the balance is lost due to the surface state of the arcuate guide surface 182 and the imaging unit base 158, and it is bounced by the pushing edge 166 and collides with the rear edge 167 and the bottom 179A. Then, it moves while colliding with the passage defining means 233.

In this situation, even if the token 104 bounces and tries to enter between the upper surface 176 of the pushing edge 166 and the passage defining means 233, the rib 180A is pushed by the pushing edge of the pushing body 168A. Since it exists on the upper surface 176 of the part 166, it cannot enter (refer to 104A in FIG. 12).
When trying to enter at the bottom 179A of the receiving recess 177A, it is blocked by the rib 180B and cannot enter (see 104C in FIG. 12).
When trying to enter at the rear edge 167, it is blocked by the rib 180C (see 104C in FIG. 12).

When the token 104 attempts to enter between the ribs 180A and 180B, the token 104 is blocked by the ribs 180A and 180B (see 104B in FIG. 12).
Similarly, if the token 104 attempts to enter between ribs 180B and 180C, it is blocked by both ribs 180B and 180C.
Therefore, the token 104 does not enter between the upper surface 176 of the pushing edge 166 and the rear edge 167 and the passage defining means 233.

In this movement process, the light received by the first timing sensor 198 passes through the reference through holes 198A, 198B, 198C of the disk 196 that rotates together with the pushing edge 166 immediately before the token 104 reaches the imaging position of the imaging device 106. Since the unit 206 receives light, the first timing sensor 198 outputs the reference signal SS.
On the other hand, since the light receiving unit 210 of the second timing sensor 200 receives light through the angle dividing holes 200A, 200B,..., The second timing sensor 200 outputs a count signal CS.
The timing signal output circuit 202 resets to zero based on the reference signal SS and counts up the count signal CS.
When the count-up value reaches a predetermined number, a light projection signal is output to the light projection device 192 of the imaging device 106, and an image pickup signal is output to the camera 190.

As a result, when the token 104 reaches the imaging position of the camera 190 on the imaging unit base 158, the light projecting device 192 projects light, and the token 104 is instantaneously irradiated with a large amount of light, and the camera 190 performs an imaging process. .
As described above, the token 104 slides on the imaging unit base 158 formed of the dark-colored resin that has been satin-finished.
The projection light from the light projecting device 192 passes through the token 104 and then reaches the upper surface of the pushing edge 166 and the upper surface of the concave groove 181, so that the upper surface of the token 104 is behind the token transfer body 170 and the guide body 128. Never become.
Further, since the upper surface of the pushing edge 166, the upper surface of the imaging unit base 158 and the upper surface of the concave groove 181 are satin-like, the projection light is irregularly reflected, and since they are dark, the reflectance due to color is low.

Therefore, even if the projection light is a large amount of light, the reflectance toward the camera 190 is low, so that the contour and surface pattern of the token 104 can be clearly imaged.
The image acquired by the camera 190 is converted into predetermined image information by the image information unit 214 and output to the comparator 218.
This image information is compared in the comparator 218 with the reference image information representing the authentic token from the reference image information unit 216.
The output of the comparator 218 is discriminated in the discriminator 220, and the discriminator 220 outputs the genuine token signal TS or the false token signal FS .
The token 104 that has passed through the imaging device 106 is turned about 90 degrees while passing through the imaging path 188, and then sent out from the outlet 326 to the sorting device 108.

The pushing edge 166 can be formed not in the token transfer body 170 but in a linear motion body.
However, by forming the token transfer body 170, other devices can be arranged around the imaging path 188, so that there is an advantage that the entire device can be reduced in size.

Next, the token selection device 102 provided with the token image acquisition device 100 of the present invention will be described.
Since the token sorting device 102 is obtained by adding a sorting device 108 to the token image obtaining device 100 described above, description of the token image obtaining device 100 is omitted.

The distribution device 108 will be described.
The distribution device 108 has a function of distributing the token 104 sent from the outlet 326 of the token image acquisition device 100 into a genuine token and a false token based on the determination result of the determination device 220.
Therefore, the sorting device 108 can be changed to another device having the same function.
Distributing device 108 of this embodiment includes a downward guide passage 332 disposed on the base 13 4 adjacent the outlet 326, the deflecting member 334, the branch passage 336 and an actuator 338.

First, the downward guide passage 332 will be described with reference to FIG.
The downward guide passage 332 has a function of guiding the token 104 received from the outlet 326 to the genuine token outlet 184 or the false token outlet 186.
Therefore, it can be replaced with another configuration having the same function.
In the present embodiment, the downward guide passage 332 is disposed below the outlet 326, is formed in a channel-like cross-sectional shape, extends in a direction away from the imaging device 106, and its bottom surface 340 is formed in a downward slope that descends as it moves away. Has been.
The passage width is preferably about 1.1 times the maximum diameter of the target token. This is to reduce the size.
In addition, the inclination angle of the bottom surface 340 is preferably an angle at which the token 104 on the bottom surface 340 can naturally fall by its own weight.
This is because even if the token 104 advances to the downward guide passage 332 at a low speed, the token 104 is distributed without being retained.
Downward guide passage 33 2 is authentic token passage, its extension direction end portion is authentic token outlet 184.

Next, the deflecting body 334 will be described.
The deflector 334 has a function of guiding the token 104 to different paths based on the authentic token signal TS or the false token signal FS from the discriminator 220.
Therefore, the deflector 334 can be changed to another device having a similar function.
Deflecting member 334 in the present embodiment is arranged in the sorting opening 341 formed in the middle of the bottom 3 40.
The distribution opening 341 is a rectangular opening.
The deflecting body 334 is a rectangular plate-like body that is slightly smaller than the distribution opening 341, and one end thereof is fixed to the rotating shaft 342 of the actuator 338.
The rotating shaft 342 is disposed at the downstream end of the sorting opening 341, and the deflecting body 334 is disposed to be inclined so as to form a part of the bottom surface 340 in the normal state.
The tip of the deflector 334 on the outlet 326 side is locked and held by a stopper (not shown) at a position continuous with the bottom surface 340.
This position is the standby position SP.
When the actuator 338 is actuated, the actuator 338 is rotated counterclockwise in FIG. 7, and is locked and held by a stopper (not shown) at a chain line position inclined about 45 degrees with respect to the horizontal line.
In this case, the deflecting member 334 is located on the extension of the guide slope 344 inclined at approximately 45 degrees which is formed on the lower surface of the positioning member 252 traverses substantially the entire downward guide passage 33 2.
This position is the deflection position DP.

Next, the branch passage 336 that is a false token passage will be described.
Branch passage 336 is positioned below the sorting opening 341, a passage sectional channel shaped extending in the perpendicular direction to the plan view down the guide passage 33 2.
Bottom 34 5 of the branch passage 336 is formed in a downward slope in the direction away from the downward guide passage 33 2.
This inclination angle is an angle at which the token 104 can slide down by its own weight.
The width of the branch passage 336 is preferably about 13 times the assumed maximum token diameter.
This is to prevent token jam due to the rampage of the token 104.
The exit of the base 134 of the branch passage 336 is a fake token exit 186.

The token 104 that is moved while being guided by the pushing edge 166 toward the outlet 326 on the arcuate guide surface 182 is sent out from the end surface of the arcuate guide surface 182 in a tangential direction at a high speed.
It sent token 104 to fall downward by gravity while traveling in the horizontal direction by the inertial force proceeds from the outlet 326 to the downward guide passage 33 2.
If it is true coin token 104, since the deflecting member 334 constitutes a part of the bottom surface 340 as shown by the solid line in FIG. 7, the token 104 traveling downward guide passage 33 2, the authenticity token outlet 184 Jump out.
Token 104 in the downward guide passage 33 2, usually proceeds without being guided to the bottom surface 340.
However, if the offset or if the protruding direction traveling speed is low, the token 104 is guided by the bottom surface 340 and side walls constituting the downward guide passage 33 2.
Since the tip of the deflecting body 334 is disposed on the extended line of the bottom surface 340 or slightly below, it does not collide with the token 104 that moves at high speed.
Therefore, damage to the tip of the deflecting body 334 due to the collision of the authentic token 104 can be prevented.

When it is determined that the token 104 is the false token 104, the actuator 338 is operated for a predetermined time based on the false token signal FS, and the rotation shaft 342 is rotated counterclockwise in FIG.
Thereby, the deflecting member 334 is moved to the position DP deflecting indicated by the chain line by the rotation in the counterclockwise direction in FIG. 7 of the rotating shaft 342.
If the deflecting member 334 is positioned at the deflecting position DP, traversing the downward guide passage 33 2 the token 104 is moved.
Token 104 to move downward guide passage 33 2 is diverted downward by colliding with the deflecting member 334, it is guided to the branch passage 336.
In addition, a genuine token and a fake token can be distributed in reverse to the above description.
In other words, the genuine token exit 184 can be a false token exit 186 and the false token exit 186 can be a genuine token exit 184.

Next, the actuator 337 will be described.
The actuator 337 is, for example, a rotary solenoid 346 and is built in the base 134.
If the rotary solenoid 346 is not energized, is rotated by the built-in spring, retains the deflecting member 334 through the rotation shaft 342 in the standby position SP.
When the rotary solenoid 346 is excited, the deflecting body 334 is moved to the deflecting position DP.
The rotary solenoid 346 is excited by the distribution controller 348 based on the authentic token signal TS from the discriminator 220 and the timing signal TMS from the timing signal output device 194, and moves the deflecting body 334 to the deflecting position DP. It is demagnetized after the elapse of a predetermined time, and the deflector 334 is returned to the standby position SP.
When the false token signal FS continues, it is preferable that the rotary solenoid 346 is not demagnetized and the deflecting position DP is continued to the deflecting body 334.
This is in order to prevent a problem caused by a shift in the movement timing of the deflector 334 due to repeated deenergization.

Next, the operation of the token selector 102 will be described.
The description of the same operation as that of the token image acquisition device 100 will be omitted, and a different operation, that is, the operation of the sorting device 108 will be described.

When the discrimination signal of the discriminator 220 is the genuine token signal TS, the rotary solenoid 346 is not excited, and the deflecting body 334 is held at the standby position SP indicated by the solid line in FIG.
Since the token 104 is pushed by the pressing edge 166 is fast, proceeds downward guide passage 33 2 through the outlet 326 in a substantially horizontal state while being guided by the imaging unit based 158, after jumping out from authentic token outlet 184 The token is stored in a genuine token storage unit (not shown).

When the false token signal FS is output from the discriminator 220, the rotary solenoid 346 is excited based on the timing signal TMS from the timing signal output device 194, and before the false token reaches the deflecting body 334, it is indicated by a chain line in FIG. The deflecting body 334 is moved to the deflecting position DP shown.
As a result, the fake token 104 collides with the lower surface of the deflector 334 and is bent downward, jumps out from the fake token outlet 186 through the branch passage 336, and is held in the fake token holding unit (not shown).
When the next token 104 is a genuine token, the rotary solenoid 346 is demagnetized after a predetermined time, so that it is returned by the built-in spring and returned to the standby position SP indicated by a solid line in FIG.
Therefore, the authentic token 104 jumps out from the authentic token exit 184 without colliding with the deflecting body 334, and is then stored in the authentic token storage unit (not shown).

In the above embodiment, the imaging device is arranged above the token transfer body, but conversely, it can be arranged below the token transfer body.
In this case, the relationship between the imaging surface of the token and the edge of the token transfer body is opposite to that in the above embodiment.
