Utility Model Registration No. 2594435 (Figures 2-14, pages 1-3)

Japanese yen 500 yen, 100 yen and 50 yen bronze coins are relatively hard, so they will not deform when sandwiched between a metal coin guide and a metal extrusion.
However, bronze-based 10-yen and aluminum-based 1-yen coins can be deformed due to their relatively low hardness.
In particular, an aluminum-based 1-yen coin has a problem that its peripheral portion is deformed and deforms so that it cannot be used after being paid out several times by a coin hopper.
That is, there is a problem that the thickness of the periphery of the coin is substantially increased due to the deformation or is not a perfect circle, so that it is erroneously detected by the coin discriminator.

A first object of the present invention is to prevent deformation of a coin when paying out a coin made of a soft material using a coin hopper.
A second object of the present invention is to provide a coin guide for preventing deformation of coins at a low cost.
A third object of the present invention is to provide a coin guide that does not damage coins made of a soft material even when a rotating disk rotates forward and backward.

In order to achieve this object, a coin hopper according to the present invention is configured as follows.
That is, the invention of claim 1, a bowl for storing coins, a rotating disk having a pushing piece to push the coin located at the bottom of the bowl, and, located below the rotary disk, and, together with the rotary disk have a coin guide for guiding the coin to rotate in the rotating disc is rotatable in the rotational direction and the opposite direction to pay out the coin coin hopper, the coin guide is rotatably shaft An attached roller, and a driven body disposed downstream of the roller in the rotational direction for paying out the rotating disk, and the roller and the driven body are made of a softer material than the coin; The support shaft and the driven body are fixed to a leaf spring supported in a cantilever manner and are separated in a direction away from the rotating disk. The upper end of the driven body is hemispherical or inclined, and the coin pushes down the driven body in contact with the hemispherical or inclined surface as the rotating disk rotates in the reverse direction. A coin guide for a coin hopper , wherein the coin is guided by an upper end of the driven body so as to get over the coin guide.

In this configuration, the coin is pushed by the pushing piece of the rotating disk and rotates together with the rotating disk .

In this configuration, since the support shaft and the driven body are attached to the same leaf spring, the positional relationship thereof does not change even if the leaf spring is elastically deformed.
Therefore, since the positional relationship with respect to the coin does not change, there is an advantage that the coin can be reliably guided in a predetermined direction.
In this configuration, even when the coin is pressed against the driven body with a large force, the driven body is deformed and the coin is not deformed.

In the configuration of this, the roller rotates with the movement of the coin, it does not wear the coin since there is no rubbing of the coin.
Furthermore, a roller made of a softer material than a coin has a lower hardness than a coin.
When the coin is sandwiched between the extruded piece and the coin guide, the coin guide is deformed by the coin, so that there is an advantage that the coin is not deformed or worn out in a short time.

The invention according to claim 3, characterized in that in the invention of claim 1, prior Symbol roller and a larger large diameter portion than the small diameter portion and the small diameter portion in contact with the coin, the large-diameter portion is supported on said plate spring It is characterized by that .
In this configuration, the roller is rotatable about a support shaft fixed to the leaf spring.
Further, the roller is directly supported by the leaf spring by the large-diameter portion rather than the small-diameter portion that contacts the coin.
Therefore, when the coin is guided by the tip of the roller small diameter portion, the roller receives a biased force.
However, since the portion in contact with the leaf spring has a large diameter, the inclination angle is regulated by the outer periphery of the large diameter portion and the inner hole.
Therefore, the inclination of the roller is suppressed to a minute angle, and the roller can rotate smoothly.
As a result, the coin is smoothly guided by the roller.
Accordingly, since the coin does not move while rubbing the coin guide, the coin does not wear.
In other words, the coin is not deformed and is paid out smoothly.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the roller has a cylindrical shape with one end closed, and is rotatably covered on the support shaft.
In other words, the roller has a bottomed cylinder shape.
When the coin gets over the tip of the roller, the coin is smoothly guided by the shape of the tip of the roller.
Therefore, since the frictional force from the roller to the coin is small, there is an advantage that the coin is not damaged.

According to a fifth aspect of the present invention, in the invention of the fourth aspect , the roller has a flange protruding outward at the other end, the support shaft has a large-diameter portion in the middle, and one end of the leaf spring. Fixed to a support plate fixed to the plate, the roller passes through the through hole of the plate spring and protrudes toward the rotating disk, and the flange is supported by the large diameter portion of the support shaft and the plate spring by the plate spring. it characterized in that it is immovably restricted in the thrust direction.

Since the coin guide has a small diameter, it is difficult to attach the coin guide so as not to fall off the support shaft.
However, according to this configuration, the movement of the roller flange in the thrust direction is restricted by the large-diameter portion of the support shaft and the leaf spring.

In other words, the roller is rotatably supported by the support shaft and is prevented from falling off by the large diameter portion and the leaf spring.

Therefore, there is an advantage that even a small-diameter roller can be attached to the leaf spring so as to be rotatable and without falling off.

According to a second aspect of the invention, in the invention of claim 1, wherein the driven body is, the lower end is formed in a rectangular lower end of the rectangular is inserted into the rectangular hole of the support plate which is fixed to the plate spring, the upper end through the through hole of the leaf spring you characterized by projecting the rotating disk side.
According to this configuration, by fitting the rectangular portion formed on the lower end of the body in a rectangular hole of the support plate can be prevented from rotating the moving object around its axis.
In other words, the positional relationship between the inclined portion of the driven body and the coin can be fixed.
Further, by passing the through hole of the leaf spring on the end of the body, engaging the stepped portion of the body by a plate spring.
Thereby, the integrated state of the driven body and the leaf spring can be maintained.
Therefore, there is an advantage that the driven body can be easily attached to the leaf spring.

According to the invention of claim 1, the hemispherical portion forms an upward slope opposite to the rotational direction of the rotating disk at one end of the driven body.
Therefore, there is an advantage that the manufacture is easy and there is no corner portion so that the coin is not damaged.

A preferred embodiment of the present invention includes a bowl for storing coins, a through hole that is located at the bottom of the bowl and through which a coin passes, and a rotating disk that has an extruding piece adjacent to the bottom of the through hole and can be rotated forward and backward. A substantially circular guide hole on which the rotating disk is located and having a guide surface for guiding a coin; a base located at the bottom of the guide hole, through which the coin that passes through the through hole slides; and protrudes from the base In the coin hopper having the first coin guide and the second coin guide, the pushing piece is a pushing portion which is substantially located on a straight line extending in the circumferential direction from the rotation center of the rotating disk, and on the peripheral side of the pushing portion. And a pushing portion located on a line that forms an obtuse angle with respect to the straight line, the pushing portion is located between the first coin guide and the second coin guide, and the pushing portion is the first portion. The first coin guide and the second coin guide are located on the peripheral side of the two coin guides, and each of the first coin guide and the second coin guide has a resin roller rotatable on a support shaft fixed to a plate spring supported in a cantilever manner. The made roller has a small diameter portion in contact with a coin and a large diameter portion larger than the small diameter portion, the large diameter portion is supported by the leaf spring, and is disposed downstream of the roller in the discharging direction of the rotating disk. The coin guide of the coin hopper is composed of a driven body having a driven portion, and the roller and the driven body are integrally movable in a direction away from the rotating disk.

In this configuration, when the coin is jammed between the first coin guide or the second coin guide and the pushing portion or the pushing portion, the rotating disk is rotated in the reverse direction for a predetermined time.
At the time of the reverse rotation, the coin that is located in the through hole that has passed through the first and second coin guides and that is guided by the guide surface can be guided by the upper end of the driven body and can get over the first and second coin guides. .
In other words, when the rotating disk is rotated in reverse, the coin moves together with the rotating disk without being blocked by the first and / or second coin guide, so that the coin jam can be resolved by rotating the rotating disk.
Furthermore, since the driven body is made of resin, there is an advantage that even if it is a soft coin, it will not be damaged when it gets over it.

Reference example

FIG. 1 is an exploded perspective view of a coin hopper equipped with a rotating disk of a reference example .
FIG. 2 is a plan view of a coin hopper equipped with a rotating disk of a reference example (with a coin bowl removed).
3 is a cross-sectional view taken along line AA in FIG.
4 and 5 are operation explanatory views of the reference example .

The structure of the coin hopper 10 will be described with reference to FIG.
A stainless steel slide base 16 is fitted into a substantially circular guide hole 14 formed on the upper surface of the flat base 12.
The slide base 16 may be integrally molded by using the base 12 as a wear-resistant resin.
However, when configured separately, an inexpensive resin can be used, so that there is an advantage that the cost can be reduced as a whole.

The peripheral surface of the guide hole 14 is a guide surface 15 of the coin C.
A disc-shaped rotating disk 18 is horizontally arranged in the guide hole 14 with a spacer (not shown) interposed between the upper surface of the slide base 16.
Next, the rotating disk 18 will be described.
The rotating disk 18 is formed with a plurality of circular through holes 20 that are slightly larger than the coin C at equal intervals and penetrate in the vertical direction.
The through hole 20 is formed in a tapered shape that tapers downward so that the coin C can easily fall.
Therefore, the ribs 22 are located between the through holes 20.

The central portion 24 of the rotary disk 18 is raised in a mound shape and forms a ridge line so as to stir the stacked coins C.
The output shaft (not shown) of the speed reducer arranged in the base 12 passes through the center of the slide base 16 from below to above, and the tip thereof is a mounting hole (not shown) formed in the center of the rotating disk 18. Has been inserted.
The rotary disk 18 is fixed to the output shaft by a screw 26 screwed into the tip of the output shaft.
The output shaft is usually rotated counterclockwise in FIG. 2 by an electric motor 28 fixed to the end of the base 12 via a speed reducer.

The distance between the back surface of the rotating disk 18 and the top surface of the slide base 16 is set slightly larger than the thickness of the coin C.
On the back surface of the rib 22, an extruded piece 30 of the coin C is formed, and the interval between the lower end thereof and the upper surface of the slide base is set smaller than the thickness of the coin C.
The extruded piece 30 includes a pushing part 32 and an pushing part 34.
The pushing portion 32 is an end surface on the front side of the pushing rib 36 formed in an arc shape around the rotation axis of the rotating disk 18, and is a coin that falls into the through hole 20 and rotates together with the rotating disk 18. The surface is almost tangent to C.

In other words, the pushing portion 32 is adjacent to the through-hole 20, is substantially located on the line LA extending in the circumferential direction from the rotation center of the rotating disk 18, is centered on the axis of the rotating disk 18, and the guide The coin C is contacted in the vicinity of the intersection of the arc Y having the radius of the distance to the center of the coin C guided to the surface 15 and the line LA.
The pushing portion 32 is preferably in surface contact with the coin C, but may be in line contact.

The extruding part 34 is an end surface on the front side of the rotation of the extruding rib 38 formed in an arc shape around the rotation axis of the rotary disk 18, is located farther from the rotation axis than the pushing part 32, and is pushed. It is an outwardly extruded surface that is located on the rear side of the rotation with respect to the advance portion 32 and faces the circumferential direction of the rotary disk 18.
In other words, the pushing portion 34 is substantially located on the straight line LB that forms an obtuse angle with respect to the straight line LA.

Next, the coin guide 39 will be described.
A pin-shaped first coin guide 40 and a second coin guide 42 protrude through a through hole 41 that vertically penetrates the slide base 16.
The first coin guide 40 is positioned on the rotational axis side of the pushing rib 36, and the tip thereof can be positioned in an arc-shaped first relief groove 44 formed on the back surface of the rotating disk 18.

The second coin guide 42 can be positioned in the arc-shaped second escape groove 46 between the pushing rib 38 and the pushing rib 36.
As shown in FIG. 2, the first coin guide 40 and the second coin guide 42 have a straight line connecting the rotation center of the rotary disk 18 and the center of the through hole 20 with respect to a straight line LD connecting their outer peripheral surfaces. When they are almost orthogonal, they are arranged so that the inner edge of the through hole 22 is located near the straight line LD.

That is, the coin C is moved in a tangential direction with respect to the coin guides 40 and 42 so that the pushing portion 32 and the pushing portion 34 are not pressed against the coin guides 40 and 42 with a large force.
Further, the interval between the first coin guide 40 and the second coin guide 42 is set so that the coin C does not fall greatly between them.
That is, when the coin C comes into contact with the first coin guide 40 and the second coin guide 42, the periphery of the coin C is set to be a distance of 1 mm or less from the straight line LD.

Next, the structure of the first coin guide 40 and the second coin guide 42 will be described. Since both have the same structure, the first coin guide 40 will be described as a representative.
The first coin guide 40 is rotatably attached by being fitted to the support shaft 50 fixed to the free end of the leaf spring 48 fixed at one end to the back surface of the slide base 16, and the support shaft 50. A roller 52 is used.
The support shaft 50 is fixed substantially vertically to the upper surface side of the leaf spring 48.
Specifically, as shown in FIG. 3, the head 54 is formed in a hemispherical shape.
A shaft portion 56 having a diameter smaller than the diameter of the head portion is formed below the head portion 54, and a caulking portion 58 having a slightly smaller diameter than the shaft portion 56 is formed below the shaft portion 56.

The support shaft 50 is fixed to the leaf spring 48 by inserting the caulking portion 58 into the caulking hole 60 of the leaf spring 48 and caulking the caulking portion 58.
In this configuration, when the coin guide 40 or 42 needs to be replaced, it is replaced by an assembly with the leaf spring 48.
The support shaft 50 may be fixed to the leaf spring 48 by forming a screw in the caulking portion 58 and tightening with a nut from the lower surface side of the leaf spring 48.
This configuration has an advantage that only the roller 52 can be replaced.

The roller 52 is formed with a small-diameter portion 62 having an outer diameter substantially the same as the outer diameter of the head 54 and a large-diameter portion 64 continuous therebelow.
The large diameter portion 64 only needs to have a larger diameter than the small diameter portion 62, but is preferably twice to three times as large as the small diameter portion 62 as shown in FIG.
Between the large-diameter portion 64 and the upper surface of the leaf spring 48, a ring-shaped and film-like friction reducing sheet 66 is disposed in order to reduce the rotational resistance of the roller 52.
As the friction reducing sheet 66, for example, a trade name Polyslider (manufactured by Asahi Polyslider Manufacturing Co., Ltd.) is appropriate.

The height of the roller 52 is set so that the length including the sheet 66 is slightly smaller than the length of the shaft portion 56, and the roller 52 rotates without substantially sliding in the axial direction of the support shaft 50. It is like that.
The length by which the small diameter portion 62 protrudes from the upper surface of the slide base 16 is set to be the same as or slightly larger than the thickness of the coin C.
The roller 52 is made of a material having a hardness lower than that of the coin C, in other words, a material softer than the coin C.
The material of the roller 52 is a resin, for example, a polyacetal resin.
This is because polyacetal resin is excellent in wear resistance and relatively inexpensive.

Next, the coin payout device 70 will be described.
A dispensing device 70 is disposed at the dispensing outlet 72.
The dispensing device 70 includes a fixed guide 74 and a moving guide 76.
In the fixed guide 74, a roller 80 is rotatably attached to a fixed shaft 78. The fixed guide 74 is disposed on the same side as the coin guides 40 and 42 with respect to the straight line LD and beside the rotating disk 18.

The interval between the fixed guide 74 and the second coin guide 42 is such that when the coin C comes into contact with both the fixed guide 74 and the second coin guide 52, the periphery of the coin C is less than 1 mm from the straight line LD. It is set.
The movement guide 76 is provided with a lever 84 that is rotatable about a fixed shaft 82, and a roller 88 is rotatably attached to a shaft 86 that is fixed to the tip of the lever 84.

The lever 84 is applied with a rotational force in a counterclockwise direction by a spring (not shown) in FIG. 2, and is normally held at a standby position shown in FIG. 2 by a stopper 90 fixed to the base 12.
At this standby position, the distance between the fixed guide 74 and the roller 88 is smaller than the diameter of the coin C.
When the movement guide 76 is pushed by the coin C, the movement guide 76 is rotated clockwise around the fixed shaft 82, and the coin C can pass between the fixed guide 74 and the movement guide 76.

Immediately after the diameter portion of the coin C passes between the fixed guide 74 and the moving guide 76, the coin C is vigorously paid out from the payout opening 72 by the return movement of the moving guide 76 by the spring (not shown).
Between the moving guide 76 and the guide hole 14, a substantially linear exit guide 92 is formed following the guide surface 15 of the guide hole 14.
The exit guide 92 can guide the coin C by surface contact or line contact.
The distance between the straight line LD and the exit guide 92, that is, the distance between the first coin guide 40 and the exit guide 92 is set to be slightly larger than the diameter of the one-yen coin.

A photoelectric coin sensor 94 is disposed at the end of the payout port 72, detects the passage of the coin C, and outputs a payout signal.
A bowl 96 for holding coins C in a stacked state on the base 12 is fixed to the base 12 by a fixing means 98 that can be attached and detached easily.
A circular outlet is formed in the lower part of the bowl 96, and the rotary disk 18 is located inside the lower end thereof.

However, the rotating disk 18 may be located entirely in the guide hole 14 and below the bowl 96.
That is, being located at the bottom of the bowl 96 includes not only the lower end of the bowl 96 but also the case where it is disposed adjacent to the lower end of the bowl 96.
The upper part of the bowl 96 is formed in a rectangular shape, and the upper end surface thereof is opened for inserting coins C.

Next, with reference to FIG. 4 and FIG. 5, the operation of the case for paying out aluminum one-yen coins will be described.
Most of the coins C placed in the bowl 96 are located on the rotating disk 18 located at the bottom of the bowl 96.
When the rotating disk 18 rotates, the coin C in the bowl 96 is stirred, falls into the through hole 20, and is supported on the slide base 16.
The coin C supported on the slide base 16 is pushed by the pushing portion 32 and rotated together with the rotating disk 18 in the counterclockwise direction as shown in FIG.

At this time, the pushing portion 32 pushes the contact D with the arc Y passing through the center of the coin C that rotates along the guide surface 15 with the axis of the rotary disk 18 as the center.
In other words, the coin C is pushed in the direction perpendicular to the line LA passing through the center of the rotary disk 18 at the contact D.
Since the orthogonal direction is substantially tangential to the arc Y, the component force toward the guide surface 15 is small.

The coin C pushes the guide surface 15 by the resultant force of this component force and the centrifugal force generated in the coin C due to the rotation.
Since the rotational speed of the rotating disk 18, and hence the coin C, is relatively small, the coin C slides on the guide surface 15 with approximately the component force.
Therefore, the resistance due to the peripheral surface of the coin C sliding with the guide surface 15 is extremely small, and the rotational resistance of the rotating disk 18 is small, so the power consumption of the motor 28 is small.

When the rotary disk 18 further rotates, the coin C is guided by the exit guide 92.
When the coin C moves in contact with the exit guide 92, it does not contact the first coin guide 40, but when the coin C is slightly separated from the exit guide 92, it contacts the first coin guide 40 (FIG. 4 chain line). Shown).
In this case, the coin C is pressed against the outlet guide 92 by the component force of the pressing force of the pushing portion 32 and the reaction force of the first coin guide 40, and moves toward the payout opening 72 while being guided by the outlet guide 92. (Figure 4).

At this time, the pushing force of the pushing portion 32 and the reaction force of the first coin guide 40 make an obtuse angle, but since the obtuse angle is relatively small, the pinching force of the coin C is small.
Further, when the roller 52 is in contact with the coin C, the roller 52 is rotated around the support shaft 50 as the coin C moves.
Accordingly, the coin C is not rubbed and worn by the roller 52.

Furthermore, since the roller 52 is made of a material softer than aluminum, even if the coin C is pressed against the roller 52 with a large force, the roller 52 is deformed and the coin C is not deformed.
Thereafter, the coin C is guided in a predetermined posture by the exit guide 92, the first coin guide 40, the upper surface of the slide base 16, and the rear surface of the rotary disk 18.
In other words, since the posture of the coin C is limited to the space surrounded by the above, it is guided in a state substantially parallel to the slide base 16.

Further, when the rotary disk 18 rotates, the coin C comes into contact with the roller 88 and is pushed toward the second coin guide 42, and is pushed toward the payout opening 72 by the pushing portion 34.
When the coin C is sandwiched between the fixed guide 74 and the roller 88, the lever 84 is rotated clockwise (FIG. 5).
When the rotating disk 18 further rotates, the coin C is pushed by the outward pushing portion 34 and pushed out to the payout opening 72 in cooperation with the second coin guide 42.

At this time, the direction of the pressing force by the pushing portion 34 is substantially parallel to the exit guide 92, and the angle formed with the reaction force of the second coin guide 42 is relatively small even if it is an obtuse angle, so that the pin C Force does not work.
The coin C receives a pressing force from the movement guide 76, but the pressing force is small.
Further, the roller 52 rotates with the movement of the coin C and does not rub the coin C.
Furthermore, since the roller 52 is softer than the material of the coin C, when the coin C pushes the roller 52 with a large force, the small diameter portion 62 is deformed.

In this case, since the coin C pushes the upper end portion of the roller 52, the roller 52 receives an unbalanced load.
As a result, the roller 52 is microscopically inclined, but since the area of the large-diameter portion 64 is large, the inclination angle is small, and the contact per unit area with the upper surface of the leaf spring 48 (sheet 66) The pressure is small.
For this reason, in combination with the low friction surface effect of the sheet 66, the rotation of the roller 52 is smooth.

Therefore, the aluminum coin C is not worn or deformed.
Further, since the coin C is sandwiched between the movement guide 76 and the second coin guide 42 in a predetermined posture limited by the back surface of the exit guide 92, the first coin guide 40, the slide base 16 and the rotating disk 18, the posture is maintained. The coin C is maintained substantially parallel to the slide base 16.

Thereafter, the coin C is pushed between the fixed guide 74 and the moving guide 76 by the pushing portion 34 toward the payout opening 72 side, and the lever 84 is further rotated clockwise.
At this time, since the pushing portion 34 pushes out the coin C on the outward slope, the coin C is not worn and deformed as described above.
Further, the coin C maintains a state substantially parallel to the slide base 16.
Immediately after the diameter portion of the coin C passes between the fixed guide 74 and the moving guide 76, the moving guide 76 flips the coin C by the counterclockwise turning force of a spring (not shown) and throws it out from the payout opening 72.

Oite Example, Reference Examples and parts denoted by the same reference numerals have the same functions and operations as in Reference Example.
As shown in FIG. 6, the first coin guide 100 and the second coin guide 102 in Example is attached to the leaf spring 104.
The leaf spring 104 is made of spring steel, a composite structure having spring properties, resin, or the like.

The leaf spring 104 is bent at an obtuse angle, and is fixed to the back surface of the base 16 by a screw (not shown) penetrating the mounting hole 106 at one end thereof.
A circular first guide through hole 108 and a second guide through hole 110 are perforated in the mounting portion 112 at the other end of the leaf spring 104 at a predetermined interval.
A circular first driven body through hole 114 and a second driven body through hole 116 are arranged on the downstream side of the first guide through hole 108 and the second guide through hole 110 in the rotation direction of the rotary disk 18, respectively.

A support plate 118 is fixed to the leaf spring 104 at a predetermined interval in parallel with the mounting portion 112.
In other words, the leaf spring 104 is fixed to the lower surface of the leaf spring 104 between the first guide through hole 108 and the second guide through hole 110 and between the first driven body through hole 114 and the second driven body through hole 116. The support plate 118 is attached to the lower end surfaces of the spacers 120 and 122, and the screws 124 are fixed by screwing them into the spacers 120 and 122.

A circular first caulking hole (not shown) and a second caulking hole 128 are perforated in the support plate 118 relative to the first through hole 108 and the second through hole 110.
The first support shaft 130 and the second support shaft 132 are fixed to the caulking holes 128 by caulking the lower ends thereof.
The first support shaft 130 and the second support shaft 132 are made of metal, for example, stainless steel, and have the same shape.

That is, as shown in FIG. 8, a large-diameter portion 134 is formed in the middle, and the support plates 118 are sandwiched between the large-diameter portion 134 and the crimped lower end portion so that the support shafts 130 and 132 are supported by the support plate. Each is fixed to 118.
A first contact body 135 and a second contact body (not shown) are rotatably supported on the support shafts 130 and 132.
The first contact body 135 and the second contact body are a first roller 136 and a second roller 138, and are integrally formed of a softer material than the coin C, for example, a polyacetal resin having excellent mechanical strength and wear resistance.

The first roller 136 and the second roller 138 have a bottomed cylindrical shape, and are respectively placed on the support shafts 130 and 132.
That is, each of the first roller 136 and the second roller 138 has a large-diameter flange portion 140 having substantially the same diameter as the large-diameter portion 134 at the lower end, and the upper portion is a small-diameter portion 142 having the same diameter.

The first coin guide 100 is configured by covering the first support shaft 130 with the first roller 136, and the second coin guide 102 is configured by covering the second support shaft 130 with the second roller 138.
As shown in FIG. 7, when the support plate 118 is fixed to the leaf spring 104, a slight gap is formed between the upper surface of the flange portion 140 and the rear surface of the leaf spring 104, and the first roller 136 and the second roller 138 are thrust. Directional movement is limited.

As a result, the first roller 136 and the second roller 138 are supported so as to be rotatable with respect to the leaf spring 104 and without falling off.
A rectangular first driven body mounting hole 144 and a second driven body mounting hole 146 are disposed downstream of the first and second driven body through holes 114 and 116 in the rotational direction of the rotating disk 18 of the support shafts 130 and 132. Formed on the side.
First moved body 148 in these mounting holes 144 and 146, the lower end portion of the second driven body 1 5 0 are inserted respectively.

The first driven body 148 and the second driven body 150 have the same structure.
The first driven body 148 and the second driven body 150 are integrally formed of a softer material than the coin C, for example, a polyacetal resin having excellent mechanical strength and wear resistance.
Even if the coin C is pressed against the first driven body 148 or the second driven body 150 with a large force, the first driven body 148 or the second driven body 150 is deformed and the coin C is deformed. There is nothing to do.

That is, as shown in FIG. 7, the upper part is a small diameter cylindrical part 152, the lower part is a large diameter cylindrical part 154, and a step part 156 is formed in the middle.
The lower end of the large diameter cylindrical portion 154 is formed a rectangular section 15 9 by cutting both sides.
By inserting the rectangular portion 15 9 to the first mounting hole 144 and the second mounting hole 146, the detent of the first driven body 148 and the second driven unit 150 is Do play.
When the support plate 118 is attached to the leaf spring 104, the stepped portion 156 contacts the lower surface of the leaf spring 104, and the first driven body 148 and the second driven body 150 are prevented from coming off.

The top portions 158 of the first driven body 148 and the second driven body 150 are formed in a hemispherical shape.
That is, when the leaf spring 104 is fixed to the back surface of the base 16, the top portion 158 is set so as to slightly protrude from the top surface of the base 16.
Specifically, the hemispherical portion protrudes from the upper surface of the base 16.
Thereby, when the rotating disk 18 is reversed, the coin C, the movement of which is restricted by the lower surface of the rotating disk 18, pushes down the first driven body 148 and the second driven body 150 due to the inclination of the spherical surface.

That is, since the first driven body 148 and the second driven body 150 are attached to the leaf spring 104, they can be pushed down by the coin C.
Thereby, the rotating disk 18 can be reversed.
The tops 158 of the first driven body 148 and the second driven body 150 can be formed on slopes so that they can be pushed down by the coin C when the rotating disk 18 is reversed.
The first roller 136 and the second roller 138 protrude from the upper surface of the base 16 by substantially the same amount as the first driven body 148 and the second driven body 150, respectively.

Next, the extrusion roller 160 of the rotary disk 18 will be described.
The extrusion roller 160 is rotatably attached to the outside of the extrusion portion 32 on the back surface of the rotary disk 18.
That is, as shown in FIG. 6, the coin C is sandwiched with the second coin guide 102.
Specifically, as shown in FIG. 9, the roller 160 has a cylinder shape, and an inward flange 162 is formed at the upper end.

The roller 160 is integrally formed of a soft material than the coin C, for example, a polyacetal resin having excellent mechanical strength and wear resistance.
This is because when the roller 160 comes into contact with the coin C with a large force, the coin C is not deformed by the roller 160.
However, the roller 160 is preferably made of metal, such as stainless steel.
This is to prevent the roller 160 from being deformed and unable to rotate smoothly when the coin C is sandwiched by a large force.
A small-diameter portion 168 of a bearing 166 having a large-diameter receiving portion 164 at the lower end is inserted into the holding hole 170 of the rotating disk 18 and fixed with a screw 172.
Therefore, the roller 160 is supported by the large-diameter receiving portion 164 so that the flange 162 is supported by the large-diameter receiving portion 164, and is rotatably supported by the peripheral surface of the large-diameter receiving portion 164.

The bearing 166 is made of metal, such as stainless steel, and obtains a predetermined strength despite its small diameter.
Further, by inserting the small diameter portion 168 of the bearing 166 into the holding hole 170, the perpendicularity between the bearing 166 and the rotary disk 18 is regulated.
When the roller 160 and the bearing 166 are fixed to the rotating disk 18, the lower ends thereof are prevented from projecting from the lower surface (lower end of the pushing portion) of the rotating disk 18.

Further, a final extruded piece 174 is formed on the lower surface of the rotating disk 18 further outside the roller 160.
This is because, after the coin C is pushed out by the roller 160, the coin C is pushed out of the rotating disk 18 further.

Next will be described the operation of the embodiment.
In the case of Example, the coin C which has fallen into the similarly hole 20 and Reference Examples are advanced push the pushing portion 32.
When the coin C comes into contact with the first coin guide 100, the coin C is pushed toward the outlet 72 by the reaction force from the first coin guide 100 and the pushing force of the pushing portion 32.

At this time, a slip occurs between the coin C and the first conguide 100. However, since the first coin guide 100 is the first roller 136, the roller 136 rotates and guides the coin C without sliding. .
Subsequently, since the coin C is sandwiched between the second roller 138 and the pushing portion 32 of the second coin guide 102, the second roller 138 similarly guides the coin C without rotating and sliding.

Subsequently coin C is sandwiched between the fixed roller 80 and the roller 160 is pushed out further by the final pushing piece 174, it is ejected by the final rollers 16 0.
As described above, since the coin C is guided by the first coin guide 100 and the second coin guide 102, the coin guides 100 and 102 are deformed when they are squeezed with a large force. Absent.

Further, since the coin C is sandwiched and does not slide with the fixed portion, it is possible to prevent the soft coin from being worn.
Furthermore, since the coin C is pushed out by the roller 160, the sliding between the coin C and the fixed portion can be further reduced, so that the wear of the coin C can be prevented.

  The present invention can be used as a coin guide of a coin dispensing device.
