A medium diameter having an intermediate diameter between the large-diameter coin LC having the largest diameter of the pushed coin C and the small-diameter coin SC having the smallest diameter. and the center of the coin MC, go straight to the straight line SA connecting the second rotation axis R a, and the center line CL passing through the diameter center MCC in the medium-diameter coin MC, the intersection of the second pusher face 191 a and it is configured such that the top portion 196 a. In this case, the peripheral surface of the middle diameter coins MC has a center line CL second pusher face the inner peripheral side pressing surface of the inner circumferential side of 191a 192 against a contact and an outer peripheral side of the outer peripheral side pressing surface 194 a each partially line contact, Oite the top 196 a does not contact. In the case of the large-diameter coin LC as well as the medium-diameter coin MC, the circumferential surface of the large-diameter coin LC is in line contact with a part of each of the inner circumferential side pushing surface 192a and the outer circumferential side pushing surface 194a. its peripheral surface is a top 196 a does not contact. Therefore, the contact between the coin circumference and the inner peripheral side pressing surface 192 a 及 beauty outer peripheral side pressing surface 194 a for each diameter of the coin C is different.

Coin C is the rotation of the second pusher 168, the second push is pushed while contacting the circumferential surface of the coin C within two of the inner peripheral side pressing surface 192 a 及 beauty outer peripheral side pressing surface 19 4 The circular conveying path 198 is moved together with the second rotating disk 162 while maintaining a fixed position with respect to the moving body 168. In other words, since it is pushed by the inner peripheral side pressing surface 192 a and the outer peripheral pressing surface 194 a which are arranged symmetrically about the center line CL, even when the different diameters, the small diameter coin SC of the small-diameter center SCC, large-diameter center LCC of diameter center MCC and large coin LC in the middle diameter coin MC, in other words, the center of the small diameter coin SC to large coins LC is on the center line CL passing through the top portion 196 a Located in. Further, the small diameter center SCC of the small diameter coin SC is located upstream of the second forward rotation direction NR2 of the straight line SA in the second forward rotation direction NR2 of the second rotating disk 162, and the large diameter center LCC of the large diameter coin LC is It is located downstream of the straight line SA in the second forward rotation direction NR2.

The amount of protrusion of the holding members 170a, 170b, 170c, and 170d from the back surface 188 is set to an amount that does not contact the base 108 and can press the thinnest coin TC, but is the same as the second pusher 168. An amount is preferred.

As shown in FIG. 6, the holding members 170 a, 170 b, 170 c, and 170 d are generally disposed relative to the top portions 196 a, 196 b, 196 c, and 196 d. When the coin C is pressed against the second pushing portions 183a, 183b, 183c, 183d, the contact point between the peripheral surface of the coin C and the holding members 170a, 170b, 170c, 170d is second than the center of the coin C. The outer peripheral side of the rotating disk 162 is preferable. Centrifugal force acts on the coin C pushed by the second pushing portions 183a, 183b, 183c, 183d by the rotation of the second rotating disk 162, and the coin C is moved to the coin holding portions 208a , 208b, 208c, 208d . Since there is a tendency to be positioned on the outer peripheral edge side, when the peripheral surface of the coin C is pushed by the holding members 170a, 170b, 170c, and 170d, the coin C is moved toward the second rotation axis RA, and the second push It is pressed against the moving parts 183a, 183b, 183c, 183d. The holding members 170a, 170b, 170c, and 170d are retracted toward the open position RP so as not to interfere with the reception of the coin C when the coin C is received by the coin holding portions 208a, 208b, 208c, and 208d. When taking an image, the coins C are moved toward the pressing position PP so as to press the coin C against the second pressing portions 183a, 183b, 183c, 183d. Note that the pressing position PP does not mean that the coin C in a strict sense is pressed against the second pressing portions 183a, 183b, 183c, 183d, but the coin C to the second pressing portions 183a, 183b, 183c, 183d. Any position may be used as long as the peripheral surface of the surface is a close contact.

The plate cam 222 is fixed to the cover 226 by two or more pins formed on the upper surface of the plate cam 222 so as not to rotate.

The plate cam 222 has a function of moving the holding members 170a, 170b, 170c, and 170d to the pressing position PP and the opening position RP at a predetermined timing. Although the plate cam 222 is used in the first embodiment of the present invention, the present invention is not limited to this, and a groove cam or the like may be used. The plate cam 222 is configured to exhibit an eccentric ellipse around the second rotation axis RA . The peripheral surface of the plate cam 222, as shown in FIG. 19, open to the second forward direction NR2, are formed in semicircular equidistant second rotational axis R A or we second radius R2 a maintaining unit 222CR, open maintaining portion and the pressing portion 222P sequentially shortened smaller to the third radius R3 than the second radius R2 Following 222CR, following the pressing portion 222P in the range of a predetermined angle of D 3 radius R3 From the first radius to the fourth radius R4, the section in which the peripheral surface is linearly formed while the radius is successively reduced, the arc section formed by the fourth radius R4 in the range of the angle E following the section of the angle D, and the angle E Following the section, the pressing maintaining part 222CP is composed of a section in which the radius is sequentially increased from the fourth radius R4 to the fifth radius R5 within the range of the angle F, and the releasing is sequentially increased to the second radius R2 following the pressing maintaining part 222CP. Part 222R is formed. .

The cam followers 232a, 232b, 232c, and 232d are pressed against the cam surface that is the peripheral surface of the plate cam 222 by the biasing force applied to the support levers 214a, 214b, 214c, and 214d by the springs 234a, 234b, 234c, and 234d. .

When the cam followers 232a, 232b, 232c, and 232d are guided by the release portion 222R of the plate cam 222, the holding members 170a, 170b, 170c, and 170d are gradually moved from the pressing position PP to the opening position RP. Note that the positions of the holding members 170a, 170b, 170c, and 170d at the pressing position PP differ depending on the diameter of the coin C to be pressed. Therefore, in practice, the cam followers 232a, 232b, 232c, and 232d are set so as not to come into contact with the plate cam 222 from the second half of the pressing portion 222P, and the second pressing portion 183a is applied by the biasing force of the springs 234a, 234b, 234c, and 234d , 183b, 183c, 183d, the coin C is pressed.

The image sensor 248 is disposed at the end of the image sensor section 238. The image pickup device 248 employs a CCD image sensor or a CMOS image sensor for miniaturization.

Next, the timing detection unit 250 of the imaging unit 166 will be described mainly with reference to FIG. The timing detection unit 250 outputs a timing signal for setting at least the light emission timing of the light emission unit 242, the imaging timing of the image sensor 248, and the operation timing of the sorting device 104 in conjunction with the coin C being pushed. It has a function. The timing detection unit 250 includes action pieces 252 a, 252 b, 252 c, 252 d provided on the second rotary disk 162 and a timing sensor 254.

The action pieces 252a, 252b, 252c, and 252d protrude upward from the peripheral wall 179 of the second rotating disk 162, and are formed in an arc shape in plan view and a rectangular shape in side view. Effector part 252a, 252b, 252c, 252d are continuous with the second pushing portion 183a, 183b, 183c, provided corresponding to 183d, each recess M on the upstream side of the second forward direction NR2 each recess M Is formed.

The timing sensor 254 is fixed to the cover 226. The timing sensor 254 is disposed downstream of the imaging window 204 in the second forward rotation direction NR2. When any of the action pieces 252a, 252b, 252c, and 252d blocks the light beam of the timing sensor 254, the timing sensor 254 is described on the imaging window 204 and later. The coin C to be pushed by any one of the second pushing portions 183a, 183b, 183c, 183d is located in the vicinity of the coin receiving port 262.

Next, the control device 256 will be described with reference to FIG. The control device 256 includes a microcomputer 258. The microcomputer 258 receives the material signal CMS from the coin detection unit 160 and the timing signal TM from the timing sensor 254, and causes the light emitting unit 242 of the imaging unit 166 to emit light based on the material signal CMS and the timing signal TM, thereby capturing the imaging window. The image sensor 248 has a function of picking up an image of the front surface or the back surface of the coin C conveyed on 204.

In addition, since detailed description of the control apparatus 256 in the 1st Embodiment of this invention is disclosed by Unexamined-Japanese-Patent No. 2013-080360, detailed description in this specification is abbreviate | omitted.

Next, the operation of the coin image acquisition apparatus 100 will be described with reference to FIGS. Incidentally, each of the through holes 140 and the first pushing portion 154a of the first rotating disk 142, 154b, 154c, 154d, the second pushing portion of the second rotating disk 162 183a, 183b, 183c, 183d, the coin holding portion 208a, 208b, 208c, 208d, holding members 170a, 170b, 170c, 170d, support levers 214a, 214b, 214c, 214d, and cam followers 232a, 232b, 232c, 232d have the same shape and function, respectively . One of them will be described as a representative.

Coins C stored in the coin container 128 is dropped on the surface of the base 108 through the through-hole 14 0 by the rotation of the first rotating disk 142. The front or back surface of the coin C is supported by the front surface of the base 108 and is pushed by the first pushing portion 154a and is guided toward the communication portion 124 by being guided by the peripheral surface of the first circular hole 120. . In the communication part 124, the coin C is pushed out to the communication part 124 by the regulation pins 156a and 156b and the first pushing part 154a.

  At the timing when the coin C is pushed out to the communication portion 124, the coin holding portion 208a of the second rotary disk 162 is opposed to the communication portion 124, and the cam follower 232a is guided to the opening maintaining portion 222CR of the plate cam 222, and the support lever 214a is rotated around the shaft pin 216a in the rotation direction NR3, and the holding member 170a is held at the open position RP. As a result, the coin C passes through the communication part 124 and is received by the coin holding part 208a (FIG. 21). In that case, the coin detection part 160 detects the coin C which passes the communication part 124, and outputs the material signal CMS.

The coin C received in the coin holding portion 208a is pushed by the second pushing portion 183a that rotates about the second rotation axis RA , and the cam follower 232a is operated by the release portion 222R of the plate cam 222, Further, the support lever 214a is rotated around the shaft pin 216a in the direction opposite to the rotation direction NR3 by the urging force of the spring 234a, so that the holding member 170a is moved from the open position RP to the pressing position PP. (FIGS. 21 to 2 3 ).

  Then, immediately before the coin C faces the approximate center of the imaging window 204, the holding member 170a presses the circumferential surface of the coin C against the second pushing portion 183a, and the position of the second pushing portion 183a and the holding member 170a. Positioned at a predetermined position according to the relationship In the first embodiment of the present invention, the holding member 170a presses the inner peripheral side pushing surface 192a and the outer circumferential side pushing surface 194a with the top 196a sandwiched therebetween, and the coin C is held by three points and is substantially V. The center of the coin C (small diameter center SCC, medium diameter center MCC, large diameter center LCC) is stably held at a predetermined position on the center line CL passing through the letter-shaped top 196a (FIG. 24).

After that, as shown in FIG. 16, at the timing when the center line CL and the center axis CA of the imaging window 204 overlap, the microcomputer 258 causes the light emitting unit 242 to emit light based on the timing signal TM from the timing sensor 254. , imaging information imaged by the imaging element 248 is output to the microcomputer 258, the authenticity determination and denomination discriminating the coin C is performed by the microcomputer 258 based on the captured information.

  The microcomputer 258 performs a predetermined process, which will be described later, based on authenticity determination and denomination information. In the first embodiment of the present invention, the small-diameter center SCC and the large-diameter center LCC of the small-diameter coin SC or the large-diameter coin LC are on the center line CL passing through the top portion 196a. Substantially located. In other words, when the center line CL and the central axis CA of the imaging window 204 overlap, the small diameter center SCC of the small diameter coin SC and the large diameter center LCC of the large diameter coin LC are also located on the central axis CA. The imaging in the short side direction of the imaging window 204, in other words, the direction along the straight line SA of the coin C can be performed roughly symmetrically around the central axis CA in the range of the imaging window 204, and the long side of the imaging window 204 Imaging in the direction, in other words, in the direction along the central axis CA can capture the entire image including the diameter of the coin C. Strictly speaking, since the middle diameter center MCC of the middle diameter coin MC is set to a timing at which the middle diameter center MCC is located on the central axis CA, when the small diameter coin SC is imaged, the small diameter center SCC is centered. In the case of a large-diameter coin LC that is imaged slightly in front of the axis CA, the large-diameter center LCC is imaged slightly downstream from the central axis CA. There is no problem even if the authenticity determination and denomination determination of the coin C is performed assuming that it is substantially located on the central axis CA.

Then, when the coin C passes through the imaging window 204, since cam follower 232a starts to be guided by the release portion 222R of the plate cam 222, the supporting lever 214 a is being rotated to Ri shaft pin 216 a dose in the rotational direction NR3, The holding member 170a is moved from the pressing position PP toward the opening position RP, and the pressing of the coin C to the second pressing portion 183a is released. Thereby, the coin C in the coin holding portion 208 a is ready to be dropped by its own weight, are guided to the sorting device 104 provided in the second forward direction NR2 downstream imaging window 204 (FIG. 26).

  Next, the distribution device 104 will be described mainly with reference to FIGS. The sorting apparatus 104 receives the coin C 262 that receives the coin C pushed by the second rotating disk 162, the first passage 270 in which the coin C falls due to its own weight, and the coin C that has passed through the first passage 270. The first coin outlet 272 to be paid out, the second passage 276 branched from the first passage 270 to the lower inclined side of the base 108 in the middle of the first passage 270, and the branch portion of the first passage 270 and the second passage 276 , A distribution mechanism 264 that distributes the coin C to one of the first passage 270 and the second passage 276 is provided.

First, the coin receiving port 262 will be described. Coin receiving port 262 has a function of guiding the sorting mechanism 264 for sorting the coins C obtained imaging information on the denomination by the coin image capture device 100. The coin receiving port 262 is an arc-shaped hole opened in the base 108 downstream of the imaging window 204. Specifically, as shown in FIG. 5, an upstream end 262 i of the coin receiving port 262 is formed approximately 100 degrees downstream of the imaging window 204, and the downstream end 262 o is approximately the imaging window 204. It is formed 180 degrees downstream. In other words, the coin receiving port 262 and the imaging window 204 are arranged approximately symmetrically across the second rotation axis RA . Of course, the width is formed slightly larger than the diameter of the large-diameter coin LC. The length in the vertical direction along the moving direction of the coin C is set to about 1.5 times the diameter of the large-diameter coin LC. This is because even when a moving inertia force is applied to the coin C, the coin C surely falls below the base 108 and can be guided to the sorting mechanism 264. Therefore, the coin C pushed by the second pusher 168 and passed through the imaging window 204 starts to fall to the coin receiving port 262 from a position rotated about 100 degrees with respect to the imaging window 204, and approximately about the imaging window 204. At the position rotated by 180, it completely falls into the coin receiving port 262 and falls into the first passage 270 provided continuously to the coin receiving port 262.

Next, the first passage 270 will be described. The first passage 270 communicates the coin receiving port 262 and the first coin outlet 272 provided at the bottom of the frame 106. The first passage 270 has a rectangular cross section and is formed slightly larger than the diameter and thickness of the large-diameter coin LC. The first passage 270 includes a side wall 106 a of the frame 106, a back surface portion 283 that is inclined toward the inclined lower side of the base 108, that is, the coin separating and feeding device 112 side, and a back surface portion at each of an upper portion and a lower portion of the first passage 270. The first front surface portion 274 and the partition wall 284 disposed opposite to the H.283, and the side wall 285 disposed opposite to the side wall 106a of the frame 106 and connecting the rear surface portion 283, the first front surface portion 274, and the partition wall 284. ing. The first coin outlet 272 is connected to a safe (not shown).

  Next, the second passage 276 will be described. The second passage 276 is branched to the lower inclined side of the base 108, that is, the coin separating and feeding device 112 side at a substantially middle portion of the first passage 270, and has a rectangular cross section like the first passage 270, and has a large diameter coin. It is formed slightly larger than the diameter and thickness of LC. The second passage 276 is defined by the side wall 106 a of the frame 106, the first front surface portion 274 and the partition wall 284 that are disposed to face each other, and the side wall 285. The end of the second passage 276 opposite to the first passage 270 is communicated with the coin receiving box 116.

The distribution mechanism 264 will be described mainly with reference to FIG. Sorting mechanism 264 on the basis of the authenticity signal or denomination information from the microcomputer 258, having either one distributed function of the coin C and the first passage 270 and second passage 276. The distribution mechanism 264 is disposed at a branching portion where the second passage 276 branches from the first passage 270. The distribution mechanism 264 includes a flap 268 and a solenoid 282 that operates the flap 268.

The flap 268 is configured to be rotatable so that one of the first passage 270 and the second passage 276 is closed at the branch portion between the first passage 270 and the second passage 276. A swing shaft 280 that protrudes from the side surface of the lower end of the flap 268 toward the side wall 106 a and the side wall 285 is provided. Immediately above the partition 284, the swing shaft 280 is rotatably inserted into the side wall 106a and the side wall 285. The hole into which the swing shaft 280 on the side wall 285 side is inserted is formed in an arc shape, and the swing shaft 280 penetrates the side wall 285 to the side opposite to the first passage 270. On the opposite side of the side wall 285 from the first passage 270, the swing shaft 280 is connected to the solenoid 282 via a link 286 (see FIG. 7) .

One end of the link 286 is engaged with the plunger 312 of the solenoid 282, and the swing shaft 280 is rotatably inserted into the other end side. The link 286 is configured to reciprocate together with the plunger 312 of the solenoid 282. A spring 288 (see FIG. 7) is arranged between the frame 310 of the solenoid 282 and the link 286, in other words, around the plunger 312 of the solenoid 282, and the link 286 is a direction in which the plunger 312 is pulled out from the frame 310 of the solenoid 282. Is being energized.

  When the solenoid 282 is demagnetized, that is, not actuated, the plunger 312 is pulled out of the frame 310 by the biasing force of the spring 288 because the plunger 312 is not pulled toward the frame 310. The movement of the plunger 312 moves the link 286 to the opposite side of the solenoid 282, maintains the flap 268 in a position to close the second passage 276, and the coin passage 262 and the first coin outlet 272 are moved by the first passage 270. Communication is made and the coin C is paid out from the first coin outlet 272.

  On the other hand, when the solenoid 282 is energized, that is, actuated, the plunger 312 is pulled toward the frame 310 and is pulled toward the frame 310 against the biasing force of the spring 288. As the plunger 312 moves, the link 286 is moved toward the frame 310, the flap 268 is maintained at a position where the first passage 270 is closed, the coin receiving port 262 and the second passage 276 are communicated, and the coin C is received by the coin receiving portion. It is paid out from the box 116.

  Next, the operation of the coin image acquisition device 100 and the sorting device 104 will be described. Here, the case where a fake coin FC having the same diameter as the large-diameter coin LC and the small-diameter coin SC being the true coin CC and having a pattern different from the true coin CC is mixed in the bulk-like small-diameter coin SC being the true coin CC As an example.

It performs determination of diameter and pattern of the image information or we coins C obtained by the imaging unit 166, further, determines the material of the coin C is performed in the microcomputer 258 from a material signal CMS output from the coin detection unit 160 . The result of the discrimination between the small coin SC and the large coin LC by the diameter and the discrimination between the small coin SC and the large coin LC by the diameter and the timing sensor 254 from the timing sensor 254 Based on the timing signal TM, the solenoid 282 is controlled.

When the microcomputer 258 determines that the coin C is a true coin CC, the timing sensor 254 outputs the timing when the leading edge of the true coin CC reaches the upstream end 262i (see FIG. 5) of the coin receiving port 262 . Based on the timing signal TM and the determination result in the microcomputer 258, the microcomputer 258 does not output a signal for exciting the solenoid 282, and the flap 268 is maintained at a position where the inlet of the second passage 276 is closed. The inlet 262 and the first coin outlet 272 communicate with each other, and the true coin CC passes through the first passage 270 and is paid out from the first coin outlet 272.

  On the other hand, the microcomputer 258 determines that the coin C is formed of a material different from the genuine coin CC such as a small coin SC, a large coin LC, and a resin having a different pattern from the false coin FC, that is, the true coin CC. In this case, the microcomputer 258 to the solenoid 282 based on the timing signal TM output from the timing sensor 254 and the determination result in the microcomputer 258 at the timing when the tip of the false coin FC reaches the upstream end 262i of the coin receiving port 262. The link 286 is moved together with the plunger 312 toward the frame 310, the flap 268 is moved to a position where the first passage 270 is closed, and the coin receiving port 262 and the second passage 276 are communicated with each other. The fake coin FC passes through the second passage 276 and is paid out from the coin receiving box 116. It is. The first passage 270 is kept closed by the flap 268 for a time sufficient for the fake coin FC to reach the second passage 276, and the solenoid 282 is turned on before the subsequent coin C reaches the upstream end 262i of the coin receiving port 262. The link 286 is moved away from the solenoid 282 by the biasing force of the spring 288, and the flap 268 is moved to a position where the inlet of the second passage 276 is closed to prepare for the next coin C sorting.
