Next, the rotating disk 110 will be described with reference to FIGS.
The rotating disk 110 has a function of sorting the coins 102 held in a loosely stacked state in the holding bowl 108 one by one and transporting them to the ejecting device 114.
The rotary disk 110 is rotationally driven via a speed reducer 164 by an electric motor 162 (see FIG. 6).
On the rotating disk 110, circular through holes 166 are formed at equal intervals on a circle with a predetermined radius centered on the rotation axis C, and a downward cone-shaped introduction portion 168 is formed on the upper surface side of the through holes 166. Has been.
The through-hole 166 is formed to be slightly larger than the large-diameter coin 102L so that the rotating disk 110 may not be replaced even when the large-diameter coin 102L or the small-diameter coin 102S is used.
Further, a conical shape is formed at the central portion, and a central convex portion 172 (see FIG. 3) for attaching the rotating shaft 146 and stirring the coin 102 is formed.
The rotating disk 110 has a lower part in the guide hole 132 and a circumferential surface of the rotating disk 110 that is narrower than the thickness of the coin 102 with respect to the peripheral wall 150, and an upper part in the bottom hole 158 of the lower end 152 of the storage bowl 108. It is arranged with a large gap.

A first pushing portion 174 and a second pushing portion 176 for pushing the coin 102 are opposed to each of the through holes 166 on the lower surface of the rib 170 that defines the through hole 166 that is the back surface 160 of the rotating disk 110. Projecting downward.
The first pushing surface 174A and the second pushing surface 176A (see FIG. 5) of the first pushing portion 174 and the second pushing portion 176 are located on an involute curve extending from the center portion of the rotating disk 110. Yes.
Between the first pushing portion 174 and the second pushing portion 176, the first groove 178A for passing through the first restricting body 112A and the second restricting body 112B constituting the circumferential guide device 112 described later is passed. A second groove 178B for the purpose is formed.

When the rotating disk 110 rotates, the coin 102 placed thereon is stirred by the through hole 166, the central convex portion 172, etc., and the posture is changed and falls into the through hole 166.
The lower surface of the dropped coin 102 is guided by the bottom surface 144 (the upper surface of the metal plate 258) of the guide hole 132, and the outer periphery thereof is guided by the peripheral wall 150.
Then, the rotating disk 110 is rotated by the first pushing surface 174A and the second pushing surface 176A by the rotation of the rotating disk 110, and is rotated together with the rotating disk 110.
At this time, the peripheral surface of the coin 102 is guided to the peripheral wall 150, but the contact pressure with respect to the peripheral wall 150 is not based on a large contact pressure because it is mostly based on centrifugal force.
In the follow-up process, the coin 102 whose rotation is prevented by the first restricting body 112A and the second restricting body 112B of the circumferential guide device 112 is guided in the circumferential direction of the rotating disk 110, and finally the second pushing body.

In other words, the first restricting body 112A and the second restricting body 112B protrude in the movement path 182 of the coin 102.

The first restricting body 112A and the second restricting body 112B are fixed to leaf springs 184A and 184B (see FIG. 6) each having one end fixed to the second mounting portion 142 on the back surface of the hopper base 106, respectively.
As a result, the coin 102 pushed by the first pushing portion 174 and the second pushing portion 176 is prevented from being rotated by the rotating disk 110 by the first restricting body 112A and the second restricting body 112B, and the exit opening 138 side To be guided to.
In addition, when the coin 102 naturally moves to the outlet opening 138 without using only one of the first restrictor 112A or the second restrictor 112B, or without using the first restrictor 112A and the second restrictor 112B, it is necessary to arrange them. There is no.

In other words, when the diameter of the rotating disk 110 is large and the coin 102 can be guided in the circumferential direction of the rotating disk 110 by the first pusher 174 and the second pusher 176, the first restrictor 112A and the second restrictor There is no need to place 112B.
When the first restricting body 112A and the second restricting body 112B receive a predetermined lateral force from the coin 102, the leaf springs 184A and 184B are elastically deformed, and the first restricting body 112A and the second restricting body 112B become the bottom surface 144. The coins 102 can move over the coins 102 and move together with the rotating disk 110.

Next, the outlet opening 138 will be described with reference to FIG.
The outlet opening 138 is a rectangular opening in which the peripheral wall 150 of the guide hole 132 on the side of the circumferential guide device 112 is cut out over a predetermined length.
In the embodiment, since the exit of the coin 102 is defined by the first guide 188 and the second guide 192, the exit opening 138 is between them.
The length of the outlet opening 138 (the circumferential length of the guide hole 132) is sufficient for the coin 102 to pass through.
In other words, the peripheral wall 150 is formed to have a slightly longer lateral length than the diameter of the coin 102, and the first guide 188 and the second guide 192 that substantially constitute the outlet opening 138 are disposed in the opening. .

Next, the ejecting device 114 will be described with reference to FIGS.
The ejecting device 114 has a function of ejecting the coins 102 that are separated and sent one by one by the rotating disk 110 one by one.

Further, in the present embodiment, the coin guide 102 has a function of making the movement amount of the second guide 192 the same regardless of whether the small diameter coin 102S or the large diameter coin 102L is used.
The first guide 188 in this embodiment is constituted by an arcuate end 198 of a spatula-shaped sheet metal guide body 196.
More specifically, one corner of one end of the guide body 196 constitutes the first guide 188, and the other corner corresponding to the corner when the front and back surfaces of the guide body 196 are reversed is the first guide. Configure 188 .

The guide body 196 is formed with the other end 202 and the side projection 204, the side projection 204 is located in the recess 207 formed in the hopper base 106, and the other end 202 is one end of the guide ring 148. In a state where it is in contact with the arc-shaped recess 206, it is set to be positioned at a first position P1 suitable for the small-diameter coin 102S.
In this state, the linear first side surface 208 of the guide body 196 constitutes a part of the guide hole 132.
As indicated by a chain line in FIG. 4, when the guide body 196 is turned upside down, the second side surface 212 opposite to the first side surface 208 forms part of the guide hole 132.
At this time, the first side surface 208 is positioned by engaging the vertical wall 210 standing at the end of the hopper base 106 and the other end 202 by engaging the concave portion 214 of the guide ring 148.
The second side surface 212 is curved more than the first side surface 208, and the substantial radius of the guide hole 132 is increased.
In other words, the large coin 102L is guided to the outlet opening 138 by the first restrictor 112A and the second restrictor 112B, and the second guide 192 has the same movement amount as when the small coin 102S is ejected. Is set.

Next, the second guide 192 will be described with reference to FIG.
The second guide 192 is provided so as to be movable, and has a function of flipping the coin 102 between the first guide 188 and flipping it.
The second guide 192 is a roller 218 that is rotatably supported by the support shaft 216 in this embodiment.
The second guide 192 is disposed on the side of the rotary disk 110 and the first guide 188, and constitutes one side wall of the outlet opening 138.

The support shaft 216 is fixed to one end of a swing lever 224 pivotally attached to a fixed shaft 222 fixed downward on the back surface of the hopper base 106, passes through an arc-shaped elongated hole 226 of the hopper base 106, It is located at a predetermined distance from the first guide 188 and adjacent to the outlet passage 116.
As shown in FIG. 6, a biasing means 194, specifically a spring 232, is latched between a pin 228 projecting from the lower surface of the hopper base 106 and a support shaft 216 projecting downward from the swing lever 224. The roller 218 is stopped and biased counterclockwise in FIG. 4 (clockwise in FIG. 6) so as to approach the first guide 188.

The urging means 194 has a function of elastically bringing the second guide 192 closer to the first guide 188.
Usually, the rocking lever 224 is integrally formed with a locked portion 234 that is formed integrally with a locking portion 236 that is elastically formed on the back surface of the hopper base 106. The guide 188 is stationary at the standby position SP stopped at an interval smaller than the diameter of the coin 102.
The locking portion 236 is, for example, a rubber ring 238 that is externally mounted on a pin protruding from the back surface of the hopper base 106.
By configuring the locking portion 236 with an elastic body, it is possible to suppress the bouncing of the swing lever 224 and prevent the coin detection device 118 from erroneously detecting.

When a straight line passing through the center of the coin 102 advances between the first guide 188 and the second guide 192, the second guide 192 is moved to the ejection position DP as shown by the chain line in FIG. The coin 102 is flipped out to the exit passage 116 by the elasticity.
The second guide 192 is pivoted by the swing lever 224, but can be changed so as to approach and separate from the first guide 188 by linear motion.
Further, the urging means 194 can be changed to a device having a similar function such as an electromagnetic actuator and an air actuator in addition to the spring.

Next, the coin detection device 118 will be described with reference to FIGS.
The coin detection device 118 has a function of detecting a movement of the second guide 192 by the coin 102 directly or indirectly and outputting a detection signal DS.
The coin detection device 118 of the embodiment includes a second guide 192, a swing lever 224 that supports the second guide 192, an action piece 242 that moves integrally with the swing lever 224, and a detection device 244 for the action piece 242. Yes.

The action piece 242 is integrally formed with the swing lever 224, is formed at a position farther from the support shaft 216 than the second guide 192, and extends to a detected length in an arc shape with the fixed shaft 222 as a center. 246.
The detection device 244 has a function of outputting an electrical detection signal DS of “H” or “L” when the detected part 246 is detected.
The detection device 244 of the embodiment is a transmissive photoelectric sensor 248, and outputs a detection signal DS when the projection light projected from the through hole 248H (see FIG. 4) is blocked.
The photoelectric sensor 248 is fixed to the first mounting portion 140 on the back surface of the hopper base 106 via a mounting bracket 250.

In the embodiment, since the photoelectric sensor 248 is located below the hopper base 106 surrounded by the support 126, it is extremely difficult to illegally access from the outside.
When the second guide 192 is moved to the ejection position DP by the coin 102, the projected light from the through hole 248H to the light receiving unit is blocked when the detected part 246 faces the through hole 248H as shown by the chain line in FIG. To do.
By this interruption, the output of the photoelectric sensor 248 changes from “H” to “L”.
When the second guide 192 moves from the ejection position DP to the standby position SP, the detected part 246 is removed from the through hole 248H during the movement, so the output of the photoelectric sensor 248 changes from “L” to “H”.
When the output of the photoelectric sensor 248 changes from “L” to “H”, the detection signal DS is output.
By counting this detection signal DS, the number of coins 102 paid out can be known.
Therefore, the detection device 244 can be changed to another type having the same function, for example, another sensor such as a reflective photoelectric sensor or a metal sensor.
Furthermore, the coin detection device 118 can be configured by directly detecting the movement of the swing lever 224 or the second guide 192.

Next, the outlet passage 116 will be described with reference to FIG.
The exit passage 116 has a function of guiding the coin 102 ejected by the ejecting device 114.
The outlet passage 116 is a thin plate-like passage that extends in the circumferential direction of the rotating disk 110 continuously to the outlet opening 138.
The outlet passage 116 is defined by a concave groove 252 formed in the hopper base 106, a first guide 188, a second guide 192, and an outlet passage definition guide 254 covering the upper release surface of the concave groove 252, and the circumferential direction of the rotating disk 110 Is growing.
The bottom surface 256 of the concave groove 252 is disposed in the same plane as the bottom surface 144, and the lower surface of the coin 102 ejected by the ejecting device 114 is guided.
The bottom surface 144 is an upper surface of a metal (stainless steel) plate 258 formed in the shape of the guide hole 132.
By making the bottom surface 144 a conductive metal plate ", static electricity generated by friction between the resin rotating disk 110 and the coin 102 can be grounded via the bottom surface 144, so that electronic parts caused by static electricity, etc. There is an advantage that problems such as damage can be solved.
The outlet passage defining device 122 is constituted by a hopper base 106 and an outlet passage defining guide 254 in this embodiment.

Next, the temporary positioning device 259 of the first guide 188 will be described with reference to FIG.
The temporary positioning device 259 has a function of temporarily determining the guide body 196 at the first position P1 or the second position P2, and includes a first dowel hole 260, a second dowel hole 262, and a base dowel 264.
The first guide 188 is formed with a first dowel hole 260 for positioning to the first position P1 and a second dowel hole 262 for positioning to the second position P2. The first dowel hole 260 and the second dowel hole 262 are circular with a predetermined diameter.
A cylindrical base dowel 264 is formed on the surface of the metal plate 258 so as to be able to fit into the first dowel hole 260 and the second dowel hole 262.
When the first dowel hole 260 is fitted in the base dowel 264, the other end 202 is engaged with the arc-shaped recess 206, and the side protrusion 204 is engaged with the recess 207, one corner of the guide body 196 is used. An arcuate end 198 is disposed at the first position P1.
When the guide body 196 is turned upside down, the second dowel hole 262 is fitted to the base dowel 264, and the other end 202 is engaged with the recess 214, the other corner 202 is the arcuate end 198. Set to 2 position P2.

The outlet passage defining device 122 will now be described with reference to FIGS. 1-4 and 7-11.
The outlet passage defining device 122 has a function of defining the outlet passage 116.
The outlet passage 116 is defined and formed by fitting the outlet passage defining guide 254 into the concave groove 252 of the hopper base 106 and then fixing it to the hopper base 106, in other words, the frame 104 by fixing means 280 such as a screw.
In FIG. 4, the concave groove 252 is a passage extending in the lateral direction from the upper end of the guide hole 132, and its bottom surface 256 is disposed in the same virtual plane as the bottom surface 144 of the guide hole 132.
Specifically, the metal plate 258 is extended to the left end portion of the hopper base 106.
Then, a guide body 196 constituting the first guide 188 is fixed on the metal plate 258, and the outlet opening 138 is constituted together with the second guide 192.
As shown in FIG. 10, on the upper side wall 268 of the groove 252, the vertical surfaces 270 and the downward inclined surfaces 272 are alternately formed.
The lower side wall 274 of the recessed groove 252 is a slope inclined toward the guide hole 132 as shown in FIG.

Next, the outlet passage defining guide 254 will be described mainly with reference to FIG.
The outlet passage defining guide 254 has a flat plate shape and is formed of a transparent resin in an inverted L shape in plan view.
Check whether the guide body 196 is set at the first position P1 corresponding to the small-diameter coin 102S or the second position P2 corresponding to the large-diameter coin 102L, and visually check the movement state of the coin 102 in the exit passage 116 To make it possible.
However, the outlet passage defining guide 254 may be opaque.
The guide hole side side surface 276 of the exit passage defining guide 254 is formed in an arc centered on the axis of the rotation shaft 146 so as to be adjacent to the peripheral edge of the rotary disk 110 at a distance less than the thickness of the coin 102, and faces the straight side surface When 278 is fixed to the hopper base 106, it is disposed flush with the left side surface 282 of the hopper base 106.
The straight side surface 278 is formed with a downward concave portion 286 that constitutes the coin outlet 284 together with the hopper base 106.

The lower surface 288 of the outlet passage defining guide 254 is a flat surface, and has a bar shape on the lower surface of the upper end portion (left side portion in FIG. 8), and an upper side surface guide 290 having a rectangular cross section is formed protrudingly.
An outlet defining projection 292 is formed downward at the left end portion at a position slightly away from the diameter of the coin 102 from the upper side guide 290.
The amount of protrusion of the upper side guide 290 and the outlet defining protrusion 292 is the same, and is formed at a height h (thick) that is slightly larger than the thickness of the coin 102.
In other words, a downward concave portion 286 is formed on the straight side surface 278 by the upper side surface guide 290 and the outlet defining projection 292.
In the middle of the downward recess 286, an extraction recess 296 that is spherical from the straight side surface 278 toward the guide hole side surface 276 and that can insert the tip of an adult index finger is formed. This is because the coin 102 remaining in the exit passage 116 can be easily taken out with a fingertip.
Downward recess 286, which is part the upper edge 286A of the bottom surface 288, an upper side guide 290 side is a left side edge 286L, and is constituted by a right side edge 286R is a side of the outlet defining protrusions 292, taken out recess 296 It is formed in the middle of the upper edge 286A .
Accordingly, the lower surface 288 corresponding to the downward recess 286 is recessed in a spherical shape with a predetermined length from the straight side 278 toward the outlet opening 138, in other words, toward the guide hole 132, and on the upper side guide 290 side of the extraction recess 296. The upper left edge 286AL (see FIG. 9) is linearly formed at a predetermined length W1 between the left edge 286L and the upper right edge 286AR between the right edge 286R on the outlet defining projection 292 side is the predetermined length W2. In FIG.
The recess shape of the take-out recess 296 is not spherical, but may be recessed so that the coin 102 can be taken out by a tweezer-like instrument or a fingertip.

A locking projection 294 protrudes from the upper side surface (upper end portion) of the outlet passage defining guide 254 with a predetermined width.
A vertical surface 298 and an inclined surface 300 are formed in a stepped manner on the locking projection 294 so as to be opposed to the vertical surface 270 and the inclined surface 272.
The upper surface 302 of the upper end portion of the locking projection 294 is formed in parallel with the lower surface 288, and has a locking recess 308 having a width slightly larger than the width of the locking projection 294 formed on the hopper base 106 (see FIGS. 4 and 10). ) Can be engaged.
A distance H1 between the upper surface 302 and the lower end of the upper side guide 290 (see FIG. 8B) is a distance H2 between the bottom surface 256 with which the lower end 304 of the upper side guide 290 contacts and the lower surface of the locking recess 308 (see FIG. 10)).
This is because the locking projection 294 is tightly held on the hopper base 106, so that the exit passage defining guide 254 does not vibrate and does not adversely affect the payout of the coin 102.
The outlet passage defining guide 254 includes a cylindrical pin-shaped outlet passage defining guide dowel that extends downward from the lower surface 288 in the vicinity of the first through hole 314A, the second through hole 314B, the third through hole 314C, and the second through hole 314B penetrating in the vertical direction. 326 is formed to protrude.
A first through hole 314A is formed at the middle center of the outlet passage defining guide 254, and a third through hole 314C is formed adjacent to the first through hole 314A.
When the guide body 196 is disposed at the first position P1 and the first dowel hole 260 is fitted to the base dowel 264, the first through hole 314A has the same axis as the screw hole 316A formed in the through hole 214A and the bottom surface 256. Located on the line and overlaps vertically.
The second through hole 314B is the same as the screw hole 316B formed in the through hole 214B and the bottom surface 256 when the guide body 196 is disposed at the first position P1 and the first dowel hole 260 is fitted to the base dowel 264. Located on the axis and overlaps vertically.
In other words, the screw 312A as the fixing means 280 passes through the first through hole 314A and the through hole 212A and passes through the screw hole 316A on the bottom surface 144, and the screw 312B passes through the second through hole 314B and the through hole 212B through the bottom surface. The guide body 196 and the outlet passage defining guide 254 can be fixed integrally to the hopper base 106, in other words, the frame 104 by screwing into the 144 screw holes 316B, and cannot be fixed unless they overlap.
When the guide body 196 is in the second position, in other words, when the second dowel hole 262 is fitted to the base dowel 264, the through hole 212A overlaps the screw hole 316C of the bottom surface 144, and the third of the outlet passage defining guide 254 The through hole 314C overlaps the through hole 214C and the screw hole 316B, and the screws 312A and 312B can be screwed into the screw holes 316C and 316B, respectively, and fixed to the hopper base 106.
The outlet passage defining guide dowel 326 is a cylindrical pin that protrudes downward from the lower surface 288 in the vicinity of the second through hole 314B.
The outlet passage defining guide 254 is positioned by fitting into the first dowel hole 260 at the first position P1 of the guide body 196 and the second dowel hole 262 at the second position P2.

Next, an operation for fixing the outlet passage defining guide 254 to the hopper base 106 will be described.
The locking projection 294 is inserted into the locking recess 308, and the lower end portion (the right end portion in FIG. 8) of the outlet passage defining guide 254 is pushed downward while the lower end 304 of the upper side guide 290 is pressed against the bottom surface 256.
Thereafter, with the lower surface 288 pressed against the upper surface of the guide body 196, the fixing screws 312A and 312B as the fixing means 280 are passed through the first through hole 314A or the third through hole 314C and the second through hole 314B. The screw hole 316A or 316C formed in the metal plate 258 constituting the bottom surface 256 and the screw hole 316B are screwed and fixed.
Since the guide body 196 is formed to have a predetermined thickness slightly thicker than the thickness of the coin 102, the lower surface 288 is substantially parallel to the bottom surface 256.
In addition, the lower end 304 of the upper side guide 290 and the lower end of the outlet defining projection 292 are in close contact with the surface of the bottom surface 256, and the thickness is slightly larger than the thickness of the coin 102, and the lateral width is slightly larger than the diameter of the coin 102. A rectangular outlet 284 is formed on the left side 282 of the hopper base 106.
Accordingly, the outlet passage 116 is defined by a flat plate shape by the bottom surface 256, the lower surface 288 of the outlet passage defining guide 254, the upper side guide 290 and the outlet defining protrusion 292, and extends linearly from the outlet opening 138 toward the outlet 284. Is defined.

As shown in FIG. 9, an upper left edge 286AL parallel to the bottom face 256 in the width W1 is located on the left side of the take-out recess 296 at the outlet 284, and an upper right edge 286AR parallel to the bottom face 256 in the width W2 is located on the right side.
Further, the outlet opening 138 side of the take-out recess 296 is constituted by an upper edge 286A in which an upper left edge 286AL and an upper right edge 286AR are continuous.
The lower edge 286U of the outlet passage 116 is constituted by the bottom surface 256.
In other words, a passage that is slightly thicker than the thickness of the coin 102 is formed continuously on the left and right sides (upper and lower sides in FIG. 4) of the outlet passage 116 over its entire length.
Therefore, since the coin 102 moving from the outlet opening 138 toward the outlet 284 continues to be guided at both ends by the bottom face 256 and at least the left upper edge 286AL or the upper right edge 286AR, the movement posture of the coin 102 is stabilized.
As a result, there is an advantage that the payout direction of the coin 102 from the outlet 284 is stabilized.
In addition, a recess located on the upper side of the outlet passage 116 with a predetermined length from the outlet 284 to the outlet opening 138 is formed in the upper middle of the outlet 284 by the take-out recess 296.

In FIG. 8C, a long groove 318 extending inward from the guide hole side surface 276 facing the take-out recess 296 of the lower surface 288 is a groove for moving the head of the second guide 192.
When the outlet passage defining guide 254 is normally fixed to the hopper base 106 and the coin 102 stays in the outlet passage 116, the tip of the coin 102 is positioned approximately flush with the outlet 284 (shown by a chain line in FIG. 4).
When the coin 102 stays in the exit passage 116, when the fingertip is inserted into the recess 196, the tip contacts the upper surface of the coin 102, so the coin 102 is pushed down by the fingertip and moved so as to be pulled out with an appropriate frictional force. The coin 102 can be pulled out from the exit passage 116.

Next, the positioning device 322 for the guide body 196 will be described mainly with reference to FIGS.
The positioning device 322 has a function of fully positioning the guide body 196 temporarily positioned at the first position P1 or the second position P2, and includes an exit passage defining guide dowel 326 and a first dowel hole 260 drilled in the guide body 196, and A second dowel hole 262 is included.
In other words, in the state where the other end 202 of the guide body 196 is engaged with the arc-shaped recess 206, the side protrusion 204 is engaged with the recess 207, and the base dowel 264 is engaged with the first dowel hole 260. Is temporarily positioned at the first position P1 of the first guide 188.
On the other hand, the guide body 196 is positioned at the second position P2 of the first guide 188 in a state where the other end 202 of the guide body 196 is fitted into the recess 214 and the base dowel 264 is fitted into the circular second dowel hole 262. .

The exit passage defining guide dowel 326 is a cylindrical protrusion protruding on the lower surface 288, and when the base dowel 264 is fitted into the first dowel hole 260, the base dowel 264 is fitted into the first dowel hole 260, and the base dowel 264 is second. When fitted into the dowel hole 262, the position is set so as to fit into the second dowel hole 262.
With this configuration, in the state where the base dowel 264 is slightly fitted and temporarily positioned in the first dowel hole 260 or the second dowel hole 262 of the guide body 196, the cylindrical outlet passage defining guide dowel 326 is formed in the first dowel hole. By fitting into 260 or the second dowel hole 262, the position is automatically performed and the main positioning is performed.
Accordingly, the first through-hole 314A or the third through-hole 314C and the second through-hole 314B of the outlet passage defining guide 254 are opposed to the through-hole 212A or 214B of the guide body 196, so that the fixing screws 312A and 312B And is fixed by screwing into the screw holes 316A and 316B of the metal plate 258.
When the guide body 196 is in the second position P2, since the through hole 314C faces the through hole 212A of the guide body 196, the screw 312A can pass through and be screwed into the screw hole 316C.

When the exit passage defining guide 254 is fixed in the correct position, the exit passage 116 has a thickness h that is slightly greater than the thickness of the coin 102 and a width W that is slightly greater than the diameter of the coin 102. A large cross-section is formed in a flat horizontally-long rectangular passage, and the outlet 284 is also formed in the same size.
As described above, the extraction recess 296 is formed at a predetermined length from the exit 284 toward the guide hole 132 side in the middle of the outlet 284, so that the portion where the extraction recess 296 is formed is the lower surface of the outlet passage defining guide 254. 288 does not exist.
In other words, the upper edge and the lower edge of the distance W1 from the left edge 286L of the upper side guide 290 to the end of the take-out recess 296 are located at a distance of the thickness h.
An upper right edge 286AR and a lower edge 286U are arranged in parallel at a distance h between the right edge 286R and the distance W2 of the outlet defining protrusion 292 at the other end.
In other words, in the vicinity of the outlet 284 of the outlet passage 116, the left and right ends are slits having a height h, and the coin 102 is guided by the bottom face 256, the upper left edge 286AL and the upper right edge 286AR at both ends.

Next, a coin size display device 332 according to the present invention will be described mainly with reference to FIG. 9 and FIG.
The coin size display device 332 has a function of directly or indirectly displaying whether the first guide 188 of the guide body 196 is located at the first position P1 or the second position P2.
Specifically, it has a function of displaying the set coin on the display unit 335 arranged in the vicinity of the outlet 284 depending on the fixing position of the guide body 196 by the fixing means 280.
As the display contents of the display unit 335, it is preferable to display a set coin size, in other words, a coin diameter.
With these displays, the operator can intuitively understand the usable coin size.
However, it can also be indirectly displayed like the first position P1 or the second position P2. Furthermore, an indirect display method such as color-coding according to the diameter of the coin, attaching a specific character or symbol, or a specific shape can be employed.
Further, since the display position only needs to be in the vicinity of the outlet 284, the display portion 335 is arranged in parallel in the same virtual plane as the outlet 284 as in the present embodiment, and the outlet passage defining guide is at a right angle to the outlet 284. It can also be placed on the top surface of 254.

The coin size display device 332 of the embodiment includes a display body 336 and a display window 364.
The display body 336 is formed in a generally T shape by the horizontal portion 338 and the vertical portion 358.
The laterally facing portion 338 is a rod having a rectangular cross section, but more precisely, a step 342 is formed in the middle.
When the guide body 196 is positioned at the first position P1, a first display portion 346 having an optimal coin size (diameter) is provided on the first end surface 344, which is one end surface of the horizontally oriented portion 338. For example, “25” corresponding to a diameter of 25 mm is formed into a floating character or a hollow character to constitute the first display unit 346. A sticker on which numbers are printed can be attached instead of floating characters.
In addition, when the first end surface 344 is positioned in a display window 364 described later, it is preferable to provide an upper surface first display unit 348 that displays the same coin size as the first end surface 344 on the upper surface of the display body 336.
This is because the coin size can be easily confirmed when the coin hopper 100 is looked down from above.

When the guide body 196 is positioned at the second position P2 on the second end surface 352 which is the other end surface of the laterally facing portion 338, an optimal coin size, for example, `` 30 '' corresponding to a diameter of 30 mm is formed into a floating character, A second display unit 354 is configured.
When the second display unit 354 is positioned in the display window 364, it is preferable to provide an upper surface second display unit 356 that displays the same coin size as the second end surface 352 on the upper surface of the display body 336.
A circular through hole 362 is formed at the end of the vertically oriented portion 358 having a rectangular cross section of the display body 336.
When the first end surface 344 is located in the display window 364, the through hole 362 is formed to be relatively capable of the first through hole 314A, and when the second end surface 352 is located in the display window 364, the through hole 362 is the third through hole. It is formed so as to be relative to 314C.
In other words, when the first display unit 346 is located in the display window 364, the through hole 362 can be arranged coaxially with the axis of the first through hole 314A, and the second display unit 354 is arranged in the display window 364. In this case, the through hole 362 cannot be arranged coaxially with the axis of the first through hole 314A or the third through hole 314C.
Further, when the second display unit 354 is located in the display window 364, the through hole 362 can be arranged coaxially with the axis of the third through hole 314C, and the first display unit 346 is arranged in the display window 364. In this case, the through hole 362 cannot be arranged coaxially with the axis of the first through hole 314A or the third through hole 314C.

The first display unit 346 and the second display unit 354 are set to be positioned at the fixed position when fitted into a rectangular display window 364 formed on the side surface 278 of the outlet passage defining guide 254.
This is because when the exit 284 is viewed from the front, the set coin size can be easily confirmed.
In the embodiment, the display body 336 is placed on the upper side of the outlet passage defining guide 254 and fixed by being fastened together with the outlet passage defining guide 254 and the guide body 196 by a screw 312A.
More specifically, when the guide body 196 is located at the first position P1, it has a first end surface 344 formed with a first display portion 346 that displays a coin size having a diameter of 25 mm corresponding to the first position P1. At the position where the end portion (the left end portion in FIG. 12) of the portion 338 is opposed to the display window 364, that is, the position where it is fitted, the through-hole 362 overlaps the first through-hole 314A and the through-hole 212A, and the screw 312A It can be screwed into the screw hole 316A through the through holes 212A, 314A and 362.
If the second end surface 352 is mistakenly opposed to the display window 364, more precisely, if the end of the lateral portion 338 having the second end surface 352 is fitted into the display window 364, the through-hole 362 becomes the first through-hole 314A. Can not be overlaid.
On the other hand, when the through hole 362 is overlapped with the first through hole 314A, the end of the lateral portion 338 on the second end face 352 side cannot be fitted into the display window 364 and cannot be relative to the display window 364.

This is because the lateral portion 338 is slightly bent into a crank shape by the step 342, and the second end surface 352 is formed farther from the through hole 362 than the first end surface 344.
Furthermore, this is because the second end surface 352 is shorter than the first end surface 344 with respect to a straight line L passing through the center of the through hole 362 and passing through the center of the vertically oriented portion 358.
In other words, when the end portion of the lateral portion 338 on the second end face 352 side is fitted into the display window 364, the through hole 362 does not overlap the first through hole 314A, and thus the screw 312A cannot be screwed.
As is clear from the above description, when the guide body 196 is located at the first position P1, the operator who tries to position the end portion on the second end face 352 side on the display window 364 has an incorrect display. In particular, the screw 312A is screwed into the screw hole 316A at the correct position where the first end surface 352 is fitted to the display window 364, and the display body 336, the outlet passage defining guide 254 and the guide body 196 are fastened together and fixed. can do.
On the other hand, if the guide member 196 is positioned at the second position P2, the through hole 362 in the insertion position in the display window 364 the end portion of the second end surface 352 side of the lateral portion 338 transmural hole 212A, the third through-hole 314C The display body 336, the outlet passage defining guide 254, and the guide body 196 can be fastened together by screwing the screw 312A into the screw hole 316C.
When the horizontal portion 338 on the first end surface 344 side is inserted into the display window 364 in this state, the through hole 362 is located at a position shifted from the third through hole 314C, and the screw 312A cannot be screwed into the screw hole 316C. There is no wrong size display on the window 364.

Next, the operation of the embodiment will be described.
In this embodiment, the small diameter coin 102S is set to a diameter of 25 mm, and the large diameter coin 102L is set to a diameter of 30 mm.
First, an operation for setting a specification suitable for the small-diameter coin 102S will be described.
The guide body 196 is temporarily positioned at the first position P1 by engaging the other end 202 with the arc-shaped recess 206, the side protrusion 204 with the recess 207, and the first dowel hole 260 with the base dowel 264. The
In other words, the first guide 188 is provisionally determined at a position suitable for the small-diameter coin 102S having a diameter of 25 mm, the through hole 212A overlaps the first screw hole 316A, and the through hole 214B overlaps the screw hole 316B.
Next, the locking projection 294 of the outlet passage defining guide 254 is inserted into the locking recess 308 of the hopper base 106 and pushed down until the lower surface 288 is in close contact with the upper surface of the guide body 196.
At the time of this depression, the outlet passage defining guide dowel 326 is fitted into the first dowel hole 260.
Accordingly, the main positioning of the outlet passage defining guide 254 is automatically performed, and the first through hole 314A and the second through hole 314B overlap the through hole 212A and the through hole 214B, respectively.
In this state, the through hole 212A of the guide body 196 and the first through hole 314A, the through hole 212B, and the second through hole 314B of the outlet passage defining guide 254 overlap each other.
In other words, by screwing the screw 312A through the first through hole 314A and the through hole 212A and screwing into the screw hole 316A, and passing through the through hole 212B and the second through hole 314B and screwing the screw 312B into the screw hole 316B, The outlet passage defining guide 254 and the guide body 196 can be fixed together.
Subsequently, the tip of the horizontal portion 338 on the first display portion 346 side of the display body 336 is inserted into the display window 364, and the through hole 362 is overlaid on the first through hole 314A.
In this state, the screw 312A passes through the through hole 362, the first through hole 314A and the through hole 212A, the screw 312B passes through the second through hole 314B and the through hole 212B, and is screwed into the screw holes 316A or 316B, respectively. The body 196, the outlet passage defining guide 254, and the display body 336 are fixed to the hopper base 106 together.
As a result, the guide body 196 is fixed at the first position P1, and together with the second guide 192, the outlet opening 138 suitable for the diameter of the small-diameter coin 102S is formed, and the upper side guide 290, the outlet defining protrusion 292, the bottom surface 258, and the lower surface A horizontally elongated outlet passage 116 is defined by 288, and an end surface of the outlet passage 116 located on the side surface of the hopper base 106 is formed as the outlet 284.

When the coin 102 payout instruction signal is received, the electric motor 162 rotates, and the rotating disk 110 is rotated clockwise in FIG. 2 via the speed reducer 164 and the rotating shaft 146.
Due to the rotation of the rotating disk 110, the small-diameter coin 102S falls into the through hole 166, and the lower surface thereof is supported by the bottom surface 144 of the guide hole 132.
Further, the small-diameter coin 102S is pushed by the first pushing portion 174 (first pushing surface 174A) and the second pushing portion 176 (second pushing surface 176A), and its lower surface slides on the bottom surface 144, and The peripheral surface is rotated along with the rotating disk 110 while being guided by the peripheral wall 150.
At this time, since the small-diameter coin 102S is pushed by the second pushing portion 176 to the outward arc surface, the small-diameter coin 102S receives a force pushing the small-diameter coin 102S toward the center of rotation, and the peripheral wall 150 of the centrifugal force due to the rotation acts on the small-diameter coin 102S. , And the contact pressure of the first side surface 208 moves in a substantially zero state.

The small-diameter coin 102S is guided in the circumferential direction of the rotating disk 110 by itself or by the circumferential guide device 112.
At this time, force is applied to the first restricting body 112A or the second restricting body 112B from the lateral direction, but the first restricting body 112A or the second restricting body 112B is kept substantially perpendicular to the bottom surface 144.
Due to the movement of the small-diameter coin 102S in the circumferential direction, the small-diameter coin 102S reaches between the first guide 188 and the second guide 192 (shown by a chain line in FIG. 4).
The second guide 192 is positioned at the standby position SP until it is moved by the small-diameter coin 102S.
The photoelectric sensor 248 does not output the detection signal DS when the second guide 192 is located in the vicinity of the standby position SP.

The small-diameter coin 102S is pushed further in the circumferential direction by the second pushing portion 176 following the first pushing portion 174, and the first guide 188 is fixed, so the second guide 192 is standby by the small-diameter coin 102S. It is moved from the position SP to the ejection position DP (shown by a chain line in FIG. 4).
As a result, the swing lever 224 is rotated clockwise about the fixed shaft 222.
In the middle of moving to the ejection position DP, the action piece 242 faces the through hole 248H and blocks the projection light from the light projecting unit, so that the output of the photoelectric sensor 248 changes from “H” to “L”.
As shown in FIG. 13, a control device (not shown) starts measuring time t from when the output changes from “H” to “L”.

The small-diameter coin 102S is passed through the second guide 192 by the resilient force of the biasing means 194 immediately after its center passes on a straight line connecting the contact point between the small-diameter coin 102S and the first guide 188 and the second guide 192. It is ejected almost laterally and discharged from the exit 284 through the exit passage 116.
As a result, the second guide 192 returns to the standby position SP.

In conjunction with the return movement of the second guide 192 to the standby position SP, the action piece 242 interrupts the light shielding to the photoelectric sensor 248, so that the projection light from the light projecting unit is received by the light receiving unit.
As a result, the output of the photoelectric sensor 248 changes from “L” to “H”.
Based on the output change from “L” to “H”, the detection device 244 outputs a detection signal DS.
Therefore, by counting this detection signal DS, the number of coins 102 paid out from the outlet 284 can be counted.
Further, after the change from “H” to “L”, if the duration “t” of “L” is shorter than the predetermined time T, no abnormal signal is output.
When the duration “t” of the output “L” of the photoelectric sensor 248 continues for a predetermined time T, for example, twice or more than usual, an abnormal signal ES can be output as an abnormal state.
For example, when the time required for paying out two coins has elapsed for “L”, the abnormality signal ES is output, and based on this, the rotation of the electric motor 162 can be stopped.

When the small coin 102S stays in the exit passage 116, the tip of the small coin 102S stops at the general outlet 284.
In this case, the fingertip is taken out and inserted into the recess 296, and the upper surface of the small-diameter coin 102S is pressed to apply a frictional force, and then the fingertip is pulled out.
As a result, the small-diameter coin 102S is pulled out by the frictional force with the fingertip and can be removed from the exit passage 116.
It can be picked up with tweezers instead of the fingertips.
In this case, since the concave portion is also formed on the bottom surface 256 side, the residual coin can be easily removed.

  In addition, since the first end surface 344 of the display body 336 is fitted to the display window 364, when the exit 284 is viewed from the front, “25” of the first end surface 344 corresponding to the diameter of 25 mm of the small-diameter coin 102S is immediately adjacent thereto. "Is visible, so there is an advantage that the diameter of the matching coin can be confirmed at a glance.

Next, an operation for changing to a specification suitable for the large-diameter coin 102L will be described.
The screws 312A and 312B are loosened and the outlet passage defining guide 254 is removed.
Next, the guide body 196 is turned over and the second dowel hole 262 is fitted into the base dowel 264 with the other end 202 engaged with the recess 214, and temporarily positioned at the second position P2. At this time, the first side surface 208 is in contact with the side wall of the hopper base 106.
In other words, very positioning since other end 202 of the first side surface 208 into contact with the side wall by sliding over the bottom surface 144 until it contacts the recess 214, Besudabo 264 to the second dowel holes 262 are fitted Can be easily done.

Next, after engaging the locking projection 294 with the locking recess 308 of the hopper base 106, the lower surface 288 is brought into close contact with the upper surface of the guide body 196.
At this time, the outlet passage defining guide dowel 326 is fitted into the second dowel hole 262, and the outlet passage defining guide 254 is positioned.
In this state, the third through hole 314C overlaps the through hole 212A and the screw hole 316C of the metal plate 258, and the second through hole 314B overlaps the through hole 214C and the screw hole 316B of the guide body 196.
Next, the tip of the horizontal portion 338 on the second display portion 354 side of the display body 336 is inserted into the display window 364, and the through hole 362 is overlaid on the through hole 314C.
In this state, the screw 312A is passed through the through hole 362, the third through hole 314C and the through hole 212A, and the screw 312B is passed through the second through hole 314B and the through hole 214C and screwed into the screw holes 316C and 316B, respectively. The outlet passage defining guide 254 and the display body 336 are fastened together and fixed.
As a result, when the exit 384 is viewed from the front, the display window 364 shows “30” on the second end surface 352 indicating the diameter of the large coin 102L corresponding to the second position P2 of the guide body 196. You can easily check the size with your eyes.

When the large-diameter coin 102L is used, it is paid out as in the case of the small-diameter coin 102S described above.
The only change is that the first guide 188 and the second guide 192 fixed at the second position P2 are different.
However, the ejection position DP of the second guide 192 is not different from the case where the small-diameter coin 102S is used.
Therefore, even when the large-diameter coin 102L is used, the coin 102 and the detection signal DS are paid out in a one-to-one relationship as in the case where the small-diameter coin 102S is used.
Further, when the large-diameter coin 102L staying in the exit passage 116 is pulled out, it can be pulled out in the same manner as the small-diameter coin 102S.
