More specifically, the present invention relates to a disk-sending device having a resin stopper that restricts a ejection roller that ejects disks one by one at a predetermined position.
In this specification, a disk refers to a circular body having a predetermined thickness, and examples of such a body include coins and game medals.

The following conventional disk delivery devices are known.
As a first prior art, there is provided a machine having a plurality of coin inlet ports through which coins are introduced from a holding tank that stores a large number of coins, a disk-shaped payout rotor that pushes the introduced coins outwards while rotating, a base that is disposed below the payout rotor and receives the coins introduced into the coin inlet port on its upper surface, a guide member that receives the coins pushed out from the payout rotor on the outside of the payout rotor and guides them towards the payout port, a guide pin that is disposed on the inside of the payout rotor in a position facing the guide member and guides the coins from the inside towards the payout port, and a guide pin that is disposed on the outside of the payout rotor in a position facing the guide member and guides the coins between the guide member and the base.

A disc ejection device is known in which the disc is ejected by pinching it between a surface and the roller, the distance between the center of the support shaft and the center of the roller being more than twice the diameter of the disc, the elastic force adjustment device having one end of the spring engaged with the oscillating lever and the other end of the spring engaged with a screw body, the screw body being screwed into a screw base so as to be freely rotatable relative to the screw base, the elastic force of the spring being adjusted by the relative rotation between the screw base and the screw body, and the oscillating lever being held in a standby position by a stopper (see, for example, Patent Document 2).
A third conventional technique includes a coin guide wall that is disposed on the base and that forms a circular storage hole with a portion open, a rotating disk that is rotatable about a rotation axis within the storage hole, that has a plurality of through holes that are disposed circumferentially at positions eccentric from the rotation axis, and that has a pusher that is disposed between adjacent through holes on the back side and protrudes toward the base, a fixed roller that is disposed outside the storage hole on the base and on one end side of the opening and is substantially fixed to the base, and an ejection roller that is disposed on the base outside the storage hole at a predetermined interval from the fixed roller and is elastically biased to approach the fixed roller, and a coin guide wall that is disposed on the base and that forms a circular storage hole with a portion open, In a coin dispensing device in which the coin is guided by the coin guide wall and pushed by the pushing front surface located on the rotational direction side of the rotating disk of the pushing body, the coin is moved from the storage hole through the opening to between the fixed roller and the ejection roller, and then ejected by the elastic action of the ejection roller, a fixed guide is arranged on the base adjacent to the fixed roller downstream in the coin ejection direction, a state is created in which the coin is sandwiched between the fixed guide and the ejection roller, and the shape of the fixed guide is set so that when the coin is sandwiched between the fixed guide and the ejection roller, the coin comes into contact across the fixed roller and the fixed guide (see, for example, Patent Document 3).

JP 2001-134800 (Figs. 1 to 3, paragraphs 0011 and 0012) JP 2010-131122 (Figs. 1 to 11, paragraph 0007) JP 2014-174720 (Figs. 1 to 17, paragraph 0007) JP 2018-012864 (Figs. 1 to 20, paragraphs 0014 and 0068)

In the first prior art, coins are pinched between a guide member and a payout roller attached to a spring-biased arm and are ejected, and the arm is prevented from moving by a stopper, maintaining a predetermined distance between the payout roller and the guide member. The stopper is made of an elastic material such as rubber, and is designed to reduce the impact when it comes into contact with the stopper.
In the second prior art, a rocking lever is attached to which a roller that ejects the disc is attached and to which a rotational force is imparted by a spring. The rotation of the rocking lever is stopped by a stopper that is fixed in place, and the stopper is made of an elastic body such as urethane rubber so as to absorb shock.
In the third prior art, the coin is sandwiched between a first fixed guide and a spring-loaded ejection roller attached to a second oscillating lever biased by a spring, and the second oscillating lever is prevented from moving by a second stopper, so that a predetermined distance is maintained between the first fixed guide and the ejection roller. There is no mention of the material of the stopper.
In the fourth prior art, the coin is sandwiched between a fixed member and a roller attached to a second movable member biased by an elastic member, and is ejected, and the second movable member is prevented from moving by a contact body, and a predetermined distance is maintained between the fixed member and the roller. There is no mention of the material of the contact body.

In a disk-discharging device, a swing lever to which a ejection roller for ejecting disks such as coins is attached is abutted against an elastic body acting as a stopper to reduce impact noise and improve durability. Taking durability, availability, and cost into consideration, urethane rubber is usually used as the elastic body, which has better mechanical properties than rubber, in other words, is durable. There are two types of urethane rubber: ether type and ester type.
Ether-based urethane rubber does not undergo hydrolysis, but its mechanical strength is inferior to that of ester-based urethane rubber, in other words, its durability is inferior, making it unsuitable for use as a stopper that receives the impact of the ejection roller in a circular media delivery device, which is struck more than millions of times.
Ester-based urethane rubber is more suitable than ether-based urethane rubber because of its excellent mechanical strength and durability. However, since ester-based urethane rubber is subject to hydrolysis, it is not suitable for long-term use in a high-humidity atmosphere. The reason for this is explained below.
The disk dispenser is usually installed in a vending machine or a currency exchange machine and used as a coin dispensing device, and is therefore used in harsh natural environments. For example, in the summer in Japan, it is used under high humidity conditions, and moisture that has entered the housing of a vending machine or the like is unlikely to escape from the housing, which may accelerate hydrolysis.
As mentioned above, since ester-based urethane rubber is hydrolyzed, when used under high humidity conditions, the hydrolysis may cause adhesion and stickiness. If this stickiness occurs in the stopper of the disk delivery device, there is a concern that the disks may not be delivered smoothly.

This concern will be explained with reference to FIG.
In Fig. 16, C is a disk, 12 is a flat base, 14 is a rotary disk which separates the disks C one by one and pushes them in the circumferential or radial direction by the push pieces 16 (inner push piece 16i, outer push piece 16e) protruding from the lower surface, 18 is a C-shaped peripheral surface guide which guides the peripheral surface of the disk C pushed by the inner push piece 16i and the outer push piece 16e, 20 is a delivery opening which opens a part of the peripheral surface of the peripheral surface guide 18, 22 is a fixed guide which is substantially fixedly held at one end of the outlet opening 20, and 24 is a spring roller. The spring roller 24 is rotatably supported on the tip of a shaft 30 which protrudes from the tip of a rocking lever 28 which is provided rotatably around a support shaft 26 which protrudes from the back side of the base 12 via an arc-shaped long hole (not shown) formed in the base 12 to the tip of the shaft 30 which protrudes from the front side of the base 12. The swing lever 28 is biased by a spring 32, which is an elastic body, so as to approach the fixed guide body 22. A stopper 38 made of urethane rubber is fixed to the swing lever 28 side of a stopper piece 34 that protrudes downward from the back surface of the base 12. The movement of a contact part 40 of the swing lever 28 is restricted by the stopper 38. In other words, the movement of the ejection roller 24 is prevented by the stopper 38, and the distance between the ejection roller 24 and the fixed guide body 22 cannot be reduced beyond a predetermined distance smaller than the diameter of the disk body C.
Therefore, when the disk C is not being fed out, the contact portion 40 of the swing lever 28 is pressed against the stopper 38 with a predetermined force by the elastic force of the spring 32.

When the disks C are being fed out, the disks C pass through holes (not shown) as the rotating disk 14 rotates, fall between the pushing pieces 16, and are separated one by one. The disks C then reach the outlet opening 20 while being guided by the peripheral guide 18.
The disk body C is initially pushed in the radial direction of the rotary disk 14 by the push piece 16 while one side of the rear side arc surface on the front side in the traveling direction is guided by the fixed guide body 22 and the other side by the ejection roller 24. As a result, the ejection roller 24 is moved away from the fixed guide body 22. Due to this movement of the ejection roller 24, the swing lever 28 is rotated clockwise in FIG. 16, so that the abutment part 40 is separated from the stopper 38. Then, when the fixed guide body 22 and the ejection roller 24 are in contact with the front arc surface of the disk body C in the traveling direction, the resultant force from the fixed guide body 22 and the ejection roller 24 acting on the disk body C due to the elastic force applied by the spring 32 to the ejection roller 24 is in the direction of returning the disk body C to the center of the rotary disk 14. However, immediately after the center of the disk C passes the straight line connecting the contact point between the disk C and the fixed guide body 22 and the contact point between the disk C and the ejection roller 24, the fixed guide body 22 and the ejection roller 24 come into contact with the rear arc surface of the disk C, so that the resultant force acting on the disk C from the fixed guide body 22 and the ejection roller 24 acts in a direction away from the rotating disk 14, and the spring 32 pulls the swing lever 28 toward the fixed guide body 22, and the ejection roller 24 pushes the rear peripheral surface of the disk C, ejecting it forcefully in a certain direction. The ejected disk C is detected by the metal sensor 42.
If the stopper 38 is not sticky, the swing lever 28 can also rotate with the movement of the ejection roller 24. Therefore, the spring 32 causes the swing lever 28 to approach the fixed guide body 22 at a predetermined speed, and the disk C is ejected at a predetermined speed and timing every time.

However, if the stopper 38 becomes sticky due to hydrolysis, the contact part 40 cannot be released immediately due to the adhesive force of the stopper 38. In other words, when the front arc surface of the disk body C in the traveling direction contacts the ejection roller 24, the sticking adhesive force of the stopper 38 prevents the rocking lever 28 (contact part 40) from immediately leaving the stopper 38, and the contact part 40 is attached to the stopper 38 until the elastic force of the spring 32 exceeds a predetermined value. When the elastic force of the spring 32 exceeds a predetermined value, the contact part 40 (rocking lever 28) instantly leaves the stopper 38. This increases the inertia force of the rocking lever 28 and the ejection roller 24, and for example, the rocking lever 28 rotates overrunning from the normal rotation position, and then moves closer to the fixed guide body 22. Since the rocking lever 28 rotates larger than usual, the spring 32 is stretched more than usual. This increases the resilience of the spring 32, and the ejection roller 24 moves toward the fixed guide body 22 at a higher speed than normal. This increases the ejection speed of the disk C, which may result in a false detection due to the metal sensor 42 being unable to ensure a sufficient detection time. In addition, moving the ejection roller 24 at a higher speed than normal may cause the ejection direction of the disk C to differ from normal, which may result in ejection failure.

The operating environment and operating conditions of the disk-discharging device in a vending machine or the like are extremely diverse, depending on the product offered, the installation location, the price setting, etc. For example, if the machine is operated frequently, even if hydrolysis occurs in the stopper 38, the abutting portion 40 and the stopper 38 are separated before the time has elapsed for the adhesion between them to increase, so the above-mentioned concern rarely occurs in reality. On the other hand, depending on the installation location of the vending machine or the like, the disk-discharging device may operate infrequently, and may not operate for, for example, more than a day.
In this case, the abutment portion 40 is pressed against the stopper 38 for a long period of time. If the stopper 38 is hydrolyzed, the stickiness of the stopper 38 will increase, which may result in the above-mentioned erroneous detection or ejection failure.
Even if the time is short, if hydrolysis has progressed, the above-mentioned defects may occur.

A ninth aspect of the present invention is configured as follows.
In the disk-body delivery device according to the eighth aspect, the stopper is a circular ring type.

In the first aspect of the invention, the disks are separated one by one by the rotation of the rotating disk, and are pushed in the same direction as the rotating disk rotates, and are pushed in the radial direction of the rotating disk at the outlet opening.
The ejection roller is rotatably attached to a rocking lever, the rocking lever is urged toward the fixed guide body by the elastic force of an elastic body, the rocking lever is engaged with a stopper, and a predetermined gap shorter than the diameter of the disk body is provided between the ejection roller and the fixed guide body.
The disk body pushed toward the outlet opening is pushed between the fixed guide body and the ejection roller, and is ejected by the elastic force of the elastic body acting on the ejection roller.
The swing lever to which the ejection roller is attached abuts against a stopper and is stopped at a predetermined position. The stopper is made of a resin that is substantially non-hydrolyzable.
Therefore, even if the disk delivery device is used in a high humidity atmosphere, erroneous detection and delivery failure do not occur, and the object of the present invention can be achieved.

Furthermore, since it is an engineering plastic, it has particularly excellent impact strength, making it suitable for use as a stopper that receives the impact of a swing lever in a disk delivery device.
In this specification, engineering plastics refers to materials that have a tensile strength of 50 MPa or more and a flexural modulus of 2.4 GPa or more at room temperature, and include polyacetal, polycarbonate, modified polyphenylene ether, and ultra-high molecular weight polyethylene.

Furthermore, the engineering plastic is a polyacetal resin.
Polyacetal resin has high impact strength, is resistant to fatigue, and is resistant to chemicals, so when used as a stopper for the rocking lever of a disk-discharge device, it has the advantages of being highly durable and not requiring any consideration of the use of chemicals during maintenance.

Furthermore, because the stopper is ring-shaped, the machining area is small, which has the advantage that it can be manufactured quickly and inexpensively.

The stopper is ring-shaped with a cylindrical hole and a conical hole formed continuous with the struck part of the cylindrical hole. The ring shape has the advantage that the struck part with the abutting part only needs to be formed smoothly, so the machining area is small and it can be manufactured cheaply in a short time. In addition, the conical hole has the advantage that the struck part of the stopper and the cylindrical hole are connected via the conical hole, so the struck part and the conical hole are connected at an obtuse angle, which prevents cracks from occurring at the obtuse angle.

The stopper is fixed to a stopper support piece provided on the base on which the rotating disk is rotatably supported by a flat head screw that passes through the conical hole and cylindrical hole. The conical outer surface of the flat head screw is fixed in intimate contact with the conical surface of the conical hole. A thrust force acts in the axial direction on the threaded portion of the flat head screw due to the reaction force of the conical surface of the conical hole. This creates an anti-rotation effect between the male threaded portion of the flat head screw and the female threaded portion of the nut, which has the advantage of making it less likely to loosen.

The stopper is fixed to a stopper support piece provided on a bracket fixed to the base and to which the pivot shaft of the pivot lever, on which the ejection roller is rotatably supported, is fixed. This means that even if the positional relationship of the ejection roller to the fixed guide body is changed, the positional relationship between the pivot lever and the stopper does not change. In other words, there is an advantage in that even if the positional relationship of the ejection roller is changed, there is no need to change the positional relationship of the stopper.

Furthermore, an attachment hole is formed in the stopper support piece, and the stopper is fixed to the stopper support piece by a countersunk screw that passes through the cylindrical hole, the conical hole, and the attachment hole formed in the stopper. A thrust force acts in the axial direction on the threaded portion of the countersunk screw due to the reaction force of the conical surface. This creates an anti-rotation effect between the threaded portion of the countersunk screw and the threaded portion of the nut, which has the advantage of making it less likely to loosen.

As the rotating disk rotates, the disks are separated one by one and pushed in the same direction as the rotating disk rotates, and are pushed in the radial direction of the rotating disk at the outlet opening.
The ejection roller is rotatably attached to the oscillating lever, the oscillating lever is urged toward the fixed guide body by the elastic force of a spring, the abutment portion of the oscillating lever is engaged with a stopper attached to a stopper support piece protruding from the bracket, and a predetermined gap smaller than the diameter of the disk body is provided between the ejection roller and the fixed guide body.
The disk body pushed by the rotating disk at the outlet opening is pushed between the fixed guide body and the ejection roller, and is ejected by the elastic force of the spring acting on the ejection roller. In the middle of the movement of the ejection roller toward the fixed guide body, the contact part of the swing lever contacts a stopper, and the movement is stopped. The stopper is made of a resin that is substantially not hydrolyzed.
Therefore, even if the disk delivery device is used in a high humidity atmosphere, erroneous detection and delivery failure do not occur, and the object of the present invention can be achieved.

Furthermore, the stopper is configured in a ring shape by a cylindrical hole and a conical hole formed continuously with the cylindrical hole on the side of the striking portion,
The nut is fixed to the stopper support piece by a countersunk head screw that passes through the conical hole and the cylindrical hole. The reaction force of the conical surface acts on the threaded portion of the countersunk head screw in the axial direction. This creates an anti-rotation effect between the threaded portion of the countersunk head screw and the threads of the nut, which has the advantage of making it less likely to come loose.

First Embodiment With reference to FIG. 1, an outline of a disk delivery device 100 according to a first embodiment of the present invention will be described.
The disk delivery device 100 will be generally described with reference to FIG.
The disk body delivery device 100 has a function of sorting and dispensing the randomly piled disk bodies C one by one. In this embodiment 1, the disk body delivery device 100 mainly comprises a coin storage container 102, a base 104, a base 106, a peripheral guide body 108 (see FIG. 2), a rotating disk 110, a regulating body 112 (see FIG. 2), and an ejection device 113 (a fixed guide body 114, an ejection roller 116, etc.).
However, the disk dispensing device 100 of the present invention only needs to include at least the coin storage container 102, the base 106, the peripheral guide 108, the rotating disk 110, the regulating body 112, and the ejection device 113, and various modifications having substantially the same action and effect are possible.

First, the coin storage container 102 will be described.
The coin storage container 102 has the function of storing the received discs C in a bulk state, and in this embodiment 1, it has a roughly vertical cylindrical shape, with an upper portion 102U being rectangular, a lower portion 102L being circular, a middle portion 102M being formed as a slope connecting the upper portion 102U and the lower portion 102L, and a rectangular flange 102F for mounting is formed at the lower end.
A circular container bottom hole 117 having a diameter slightly larger than that of the rotating disk 110 is formed in the lower portion 102L.

Next, the base 104 will be described.
The base 104 has a base 106 attached like a ceiling, and has a function of incorporating a rotation drive device and a control unit for the rotary disk 110, and in this embodiment 1, it is a channel type that is trapezoidal when viewed from the side, with the front side F being low and the rear side R being high, and as a result, the upper surface 104U is formed as a slope that slopes downward from the rear side R to the front side F. However, the upper surface 104U can also be formed horizontally.

Next, the substrate 106 will be described with reference to FIGS.
The base 106 has at least the function of guiding the lower surface of the disk C which is rotated by the rotating disk 110. In this embodiment 1, the base 106 is a rectangular flat plate having a predetermined thickness, which is fixed to the upper surface 104U of the base 104 which is inclined downward toward the front. In this embodiment 1, the base 106 is formed into a vertically long rectangle in order to guide the disk C which is pushed by the rotating disk 110, and in order to accommodate the fixed guide body 114 and the ejection roller 116. However, the shape of the base 106 is not important as long as it has the same function.

Next, the peripheral guide 108 will be described with reference to FIG.
The peripheral guide 108 has a function of guiding the peripheral surface of the disk C that is moved while sliding on the base 106 by the rotating disk 110, and has a plate thickness slightly thicker than the thickness of the thickest disk C expected to be used. In this embodiment 1, for example, when a 1 yen coin is the disk C, the peripheral guide 108 has a plate thickness of 2.0 mm, which is slightly thicker than the thickness of the disk C, which is 1.5 mm, and a peripheral guide wall 118 of a predetermined diameter, i.e., a diameter slightly larger than the diameter of the rotating disk 110, is formed in the center of the rectangular plate-like body.
The peripheral guide wall 118 is a guide surface for the disk C, and a portion of the peripheral guide wall 118 is open over a length equal to or greater than the diameter of the disk C to form an outlet opening 122. Therefore, the peripheral guide body 108 is formed into a C-shape as a whole.

Next, the peripheral guide wall 118 will be described.
The peripheral guide wall 118 has a function of guiding the disk C pushed by the pushing portion 128 (FIG. 2) of the rotating disk 110, more specifically, by the inner pushing portion 128i (FIG. 3), and is a circular hole formed so as to penetrate the peripheral guide 108 from the top to the bottom, and its depth is formed slightly deeper than the thickness of the thickest disk C expected to be used. The diameter of the peripheral guide wall 118 is formed to be almost the same as the diameter of the rotating disk 110. Therefore, the peripheral guide wall 118 is a circular hole arranged on the outside of the pushing portion 128.

The exit opening 122 will now be described primarily with reference to FIG.
In the present embodiment, the outlet opening 122 is opened at a predetermined length on the lower side of the peripheral guide wall 118 in the inclination direction of the base 106, and a distance d is formed between the left end 118L and the right end 118R. In the present embodiment, the distance d between the left end 118L and the right end 118R is approximately twice the diameter of the disk C to be sent out. However, the length of the distance d may be any length that allows the disk C to pass through and be ejected by the ejection device 113.
The rotation axis CS of the rotating disk 110, the central axis of the peripheral guide wall 118, and the central axis of the container bottom hole 117 of the coin storing container 102 are coincident with each other.

Next, the rotating disk 110 will be described mainly with reference to FIGS.
The rotating disk 110 has the function of separating the disk bodies C one by one, rotating them together with the rotating disk 110, and further pushing them in the radial direction of the rotating disk 110. In this embodiment 1, the rotating disk 110 includes at least a disk-shaped disk main body 124, through holes 126 (126A to 126E) serving as a separation portion 125 formed in the eccentric portion of the disk main body 124, and pushing portions 128 (128A to 128E) formed on the back surface.

First, the disk body 124 will be described.
The disk body 124 is formed by integral molding of metal or wear-resistant resin, and is fixed to the tip of the rotating shaft 130 perpendicular to the base 106, so that at least the upper part in the thickness direction is placed in the container bottom hole 117 of the coin storage container 102, and the pushing part 128 at the lower end is rotated at a predetermined speed inside the circumferential guide wall 118. In this embodiment 1, the rotating shaft 130 is rotated via a reducer 133 by an electric motor 131 attached to the back side of the base 106. Therefore, the axis of the rotating shaft 130 and the rotating disk 110 also coincides with the axis CS. In addition, the circumferential guide wall 118 is located outside the pushing part 128. Since the rotating shaft 130 perpendicularly stands against the base 106, the rotating disk 110 also inclines downward toward the front and rotates in a plane parallel to the base 106. In other words, the base 106 and the rotating disk 110 are arranged parallel to each other with a predetermined gap therebetween. The gap is the distance between the lower end of the pushing portion 128 formed on the back surface of the rotating disk 110 (disc body 124) and the upper surface of the base 106; the lower end of the pushing portion 128 does not come into contact with the base 106, and when the thickest disc body C expected to be used slides on the base 106, a small gap is formed between the upper surface of the disc body C and the back surface of the disc body 124.

A spindle-shaped agitating portion 132 is formed around the rotation shaft 130 on the upper surface side of the disk main body 124, and agitates the disks C piled up in the coin storage container 102 when the rotating disk 110 rotates.
A cylindrical gap restricting portion 134 protruding downward is formed around the rotation axis 130 on the back side of the disk body 124, and restricts the lower end of the pushing portion 128 from rotating at a distance from the base 106 that is equal to or less than half the thickness of the thinnest disk body C. A sheet made of a low-friction material can be interposed between the lower end face of the gap restricting portion 134 and the base 106 to reduce frictional resistance.

Next, the through hole 126 which is the separating portion 125 will be described.
The separating unit 125 has a function of separating the disks C piled up in the coin storage container 102 one by one. In this embodiment 1, the separating unit 125 is a circular through hole 126 that penetrates the disk body 124 from top to bottom at an eccentric position of the disk body 124. In this embodiment 1, five through holes 126 (126A to 126E) are formed, and therefore, for convenience, they are indicated by adding alphabets A to E to the number 126, and when an individual explanation is given, a combination of the number and alphabet is used, and when an individual explanation is not necessary, only the number 126 is used as a general term.
The through holes 126 have the function of stirring the disks C piled up in the coin storage container 102 and dropping them one by one into the through holes 126, thereby separating the disks C one by one. In this embodiment 1, there are five circular through holes 126A to 126E formed at equal intervals at an eccentric position of the disk body 124. The diameter of the through holes 126 may be set to a diameter that allows the target disk C of the largest diameter to fall smoothly so as to be able to accommodate two or more disks C, or may be set to a dedicated diameter that allows a specific disk C to fall most smoothly and be processed.
When formed in this manner, the edge of the gap restriction portion 134 is petal-shaped.
On the back surface between the adjacent through holes 126A to 126E of the disk body 124, there are formed swept-back wing-shaped pushing portions 128 (128A to 128E) extending toward the periphery.

Next, the pushing portion 128 will be described.
The pushing portion 128 has a function of pushing the disk body C that has fallen into each through hole 126A-126E through a ring-shaped coin passage 136 (FIG. 3) formed between the gap regulating portion 134 and the peripheral guide wall 118 by the rotation of the rotary disk 110. In this embodiment 1, the pushing portion 128 is a protrusion that protrudes downward on the lower surface of the disk body 124, and is formed for each through hole 126 so as to cross the coin passage 136 in the radial direction. In the following description, since five pushing portions 128 (128A-128E) are formed, for convenience, they are represented by the number 128 with the alphabets A-E, and when an individual description is made, a combination of the number and the alphabet is used, and when an individual description is not necessary, only the number 128 is used as a general term. Since the configurations of the pushing portions 128A-128E are all the same, the pushing portion 128A will be used as a representative and will be described with reference to FIG. 4.

The pushing part 128A is composed of at least two parts, an outer pushing part 128e and an inner pushing part 128i. However, the pushing part 128E can form an intermediate pushing part between the outer pushing part 128e and the inner pushing part 128i. In this case, the intermediate pushing part may become the inner pushing part 128i for the outer pushing part 128e, and the intermediate pushing part may become the outer pushing part 128e for the inner pushing part 128i.

First, the outer pushing portion 128e will be described.
The outer pushing portion 128e has the function of pushing the disc body C between the fixed guide body 114 and the ejection roller 116, and in this embodiment 1, is constituted by a downward protrusion formed on the back surface of the disc body 124 at a position radially farther from the axis SC than the inner pushing portion 128i on the rotating disk 110, and is formed in an arc shape when viewed from the back surface, being a protrusion that extends in an arc shape along the outer peripheral edge of the corresponding through hole 126E.

The outer end of the outer pushing portion 128 e is located on the periphery of the rotating disk 110 .
The outer rear end 140A, which is the rear end in the forward rotation direction of the outer pushing portion 128e, has the function of pushing the disk body C when the rotating disk 110 is rotated in the reverse direction, and in this embodiment, is formed on the outermost edge of the disk main body 124 and is formed in a pointed shape in order to pull the disk body C into the peripheral guide wall 118 as much as possible.
The outer pushing portion 128e is formed in a swept-back wing shape that is positioned toward the rear side in the forward rotation direction of the rotary disk 110 as it moves away from the axis CS. As a result, the disk body C, which is pushed by the inner pushing portion 128i and guided to the outlet opening 122 by the inner regulating body 112i and the outer regulating body 112e, is pushed between the fixed guide body 114 and the ejection roller 116. Next, the disk body C is further pushed between the fixed guide body 114 and the ejection roller 116 by the outer pushing portion 128e, and then ejected by the elastic force applied to the ejection roller 116.

When the disk C is pushed by the outer pushing portion 128e at the outlet opening 122, the disk C is pushed between the fixed guide body 114 and the ejection roller 116 while receiving a force from the outer pushing portion 128e in the radial direction of the rotating disk 110.
The forward rotation direction of the rotating disk 110 refers to the rotation direction of the rotating disk 110 that allows the disks C to be dispensed (counterclockwise in FIG. 4).

Next, the inner pushing portion 128i will be described.
The inner pushing portion 128i is a protrusion that protrudes downward from the lower surface of the disk main body 124, and in this embodiment 1, it has a trapezoidal shape when viewed from the back, with the front side in the forward rotation direction of the rotating disk 110 forming the inner front surface, and the rear side in the forward rotation direction forming the inner rear end. Therefore, between the outer pushing portion 128e and the inner pushing portion 128i, an arc-shaped outer escape groove 138e centered on the axis CS of the rotating disk 110 is formed so that the outer regulating body 112e can pass through.
It is preferable that the rear end of the inner pushing portion 128i in the forward rotation direction of the rotating disk 110 is formed flush with the periphery of the through hole 126B. This is to prevent the disk C from moving (irregularly moving) by suppressing the amount of movement of the disk C that has fallen into the through hole 126A as much as possible, and as a result, to prevent unexpected trouble.
Furthermore, the front surface of the inner pushing portion 128i is formed to extend in the radial direction from the axis SC. When the disk body C is rotated while being guided in contact with the peripheral guide wall 118, the disk body C is pushed by the inner pushing portion 128i.

Next, the gap restricting portion 134 will be described.
The gap regulating portion 134 has the function of positioning the rotating disk 110 at a predetermined distance from the base 106, and in this embodiment 1, it is a protrusion that protrudes downward from the underside of the central portion of the disk body 124, and is formed by an outward surface formed flush with the periphery of the through hole 126 and an arc-shaped convex surface located below the base of the pushing portion 128, and is formed into a petal shape overall.
Between the gap regulation portion 134 and the inner pushing portion 128i, an inner escape groove 138i is formed to allow the inner regulating body 112i to pass therethrough.

Next, the guide body 112 will be described with reference to FIGS.
The regulating body 112 has a function of guiding the disk body C, which is pushed through the coin passage 136 by the inner pushing portion 128i, in the radial direction of the rotary disk 110. In this embodiment 1, the regulating body 112 is composed of a pair of inner regulating bodies 112i and outer regulating bodies 112e, which protrude upward from the base 106 at a position corresponding to the outlet opening 122 in the coin passage 136. The inner regulating body 112i and the outer regulating body 112e are disposed at approximately equal intervals between the gap regulation portion 134 and the fixed guide body 114, and their tip portions can pass through the outer escape groove 138e or the inner escape groove 138i, respectively. Since the inner regulating body 112i and the outer regulating body 112e have the same configuration, the outer regulating body 112e will be mainly described as a representative.
The outer regulating body 112e is fixed to a free end of a leaf spring 142, one end of which is fixed to the rear surface of the base 106. The leaf spring 142 is manufactured from spring steel, a composite structure having spring properties, resin, or the like.

The leaf spring 142 is flat, one end of which is fixed to the rear surface of the base 106 by a screw (not shown), and the lower end of the outer regulating body 112e is inserted into a hole at the other end and crimped to be erected.
In the first embodiment, the inner regulating body 112i and the outer regulating body 112e are made of metal or the like.

Next, the ejection device 113 will be described.
The ejection device 113 has a function of ejecting the disk body C pushed by the rotating disk 110 in a predetermined direction, and includes at least a fixed guide body 114 arranged at the outlet opening 122, and an ejection roller .

Next, the fixed guide body 114 will be described mainly with reference to FIG.
The fixed guide 114 has a function of guiding the disk C pushed by the pusher 128 (outer pusher 128e) after the disk C is guided by the guider 112, and is disposed at the front side of the outlet opening 122 in the forward rotation direction of the rotating disk 110, and is attached in a substantially fixed state to the base 106. In other words, the disk C does not move with the force pushed by the pusher 128 in the normal state, but is elastically supported so as to move back when pushed with a larger force. In the first embodiment, the fixed guide 114 is disposed in a position close to the periphery of the rotating disk 110, but may be located below the periphery of the rotating disk 110.
In this embodiment, the fixed guide body 114 protrudes upward from one end of a lever 146 rotatably supported by a fixed shaft 144 protruding downward from the back surface of the base 106, and is rotatably attached to a fixed guide body support shaft 150 that protrudes upward through a circular hole 148 formed in the base 106 and protrudes to the upper surface side. By engaging a tension spring 156 between a locking protrusion 152 protruding downward from the tip of the lever 146 and a set screw 154 protruding downward from the back surface of the base 106, a rotation force is applied to the fixed guide body 114 in the counterclockwise direction in FIG. 5, and the fixed guide body 114 is abutted against a locking protrusion 158 protruding downward from the back surface of the base 106 to prevent rotation. Referring to FIG. 3, the fixed guide body 114 is biased by the tension spring 156 so as to be rotatable toward the ejection roller 116, but is held at a stationary position SP shown in FIG. 3 by the locking protrusion 158. 3 against the elastic force of the tension spring 156, but cannot move in the opposite direction. The tension spring 156 has a much larger elastic force than a spring 168, which will be described later, and is substantially maintained in a fixed state during normal delivery of the disk C. However, if pushed by an excessive force, it can be moved, preventing excessive force from being applied to the rotary disk 110.

Next, the ejection roller 116 will be described mainly with reference to FIGS.
The ejection roller 116 has a function of pinching the disk C between itself and the fixed guide body 114 and ejecting it. In the present embodiment 1, the ejection roller 116 is unitized and configured as an ejection roller unit 160.
The ejection roller unit 160 has a function of attaching the ejection roller 116 to a predetermined position on the base 106, adjusting the positional relationship with the fixed guide body 114, and preventing the biasing force from being changed even if the position is adjusted. In this embodiment 1, the ejection roller unit 160 includes a bracket 162, a swing shaft 164, a swing lever 166, a spring 168, a stopper 172, and a position adjustment part 174.

First, bracket 162 will be described.
The bracket 162 has a function to which the swing shaft 164, the swing lever 166, the spring 168, and the stopper 172 are attached, and which constitutes the position adjustment portion 174. In this embodiment 1, the bracket 162 is formed by sheet metal processing. The bracket 162 is flat, and is integrally formed with a base portion 178 that is approximately trapezoidal in plan view, an ejection spring receiving protrusion 182 that protrudes downward from the base portion 178, and a stopper support piece 184. In addition, a circular lever shaft hole 186 formed near one side of the bracket 162, an arc-shaped long hole 188 that constitutes a part of the position adjustment portion 174 formed around the axis of the lever shaft hole 186, and an approximately rectangular ejection roller hole 192 formed on the opposite side of the lever shaft hole 186 are formed.

Next, the pivot shaft 164 will be described.
The swing shaft 164 has a function of supporting a swing lever 166 so as to be freely rotatable.
In this embodiment 1, the pivot shaft 164 is a downward shaft having one end inserted into a lever shaft hole 186 formed near one side of the base portion 178 and then fixed by crimping. A circular positioning hole 194 having a predetermined depth is formed in the crimped end of the pivot shaft 164. A positioning shaft 200 protruding downward from the base 106 is inserted into the positioning hole 194. The positioning shaft 200 can be substituted by a screw or the like screwed into the base portion 178.

Next, the rocking lever 166 will be described.
The swing lever 166 has a function of rotatably supporting the ejection roller 116. In this embodiment 1, the swing lever 166 is made of a long and narrow flat metal plate, and a cylindrical bearing 196 protruding downward is fixed to one end of the swing lever 166. In detail, the upper end of the bearing 196 is fixed in a state where it is inserted into a circular mounting hole 170 formed at one end of the swing lever 166. The bearing 196 is rotatably supported by a ball bearing 198 on the swing shaft 164.

A plurality of first ball bearings 198A and second ball bearings 198B are built into bearing 196, and a collar 202 is disposed above first ball bearing 198A, and a resin ring-type spacer 204 is disposed above that.
A resin ring-type spacer 206 is arranged below the lower second ball bearing 198B and is supported by a snap ring 208 engaged with the tip (lower end) of the oscillating shaft 164 to prevent it from falling off the oscillating shaft 164.
In other words, the swing lever 166 is rotatably supported on the swing shaft 164 by the ball bearing 198 .

A spring locking portion 210 is formed to protrude downward from the other end of the swing lever 166. A support shaft 212 (hereinafter referred to as the "spring roller support shaft 212" for convenience) protruding upward from the side of the spring locking portion 210 is fixed thereto.
The ejection roller shaft 212 is composed of a lower large diameter portion 212L and an upper small diameter portion 212S, and the ejection roller 116 is rotatably attached to the small diameter portion 212S via a ball bearing (not shown). The ejection roller 116 is disposed above a ring-shaped spacer 214 disposed above the ejection roller 116, and a snap ring 216 engaged with the upper end of the small diameter portion 212S restricts the movement in the thrust direction so as not to fall off. When the swing lever 166 is assembled to the bracket 162, the ejection roller 116 passes through the ejection roller hole 192 and is disposed above the bracket 162.

A roughly rectangular abutment piece 211 is formed downward from a portion close to the swing shaft 164 on the opposite side of the spring locking portion 210 of the swing lever 166. When the swing lever 166 is rotated by the spring 168, the abutment piece 211 abuts against the stopper 172, limiting its movement. Therefore, the abutment piece 211 may be part of the swing lever 166.

A stopper 172 is fixed to the stopper support piece 184 that protrudes downward from the end of the ejection roller hole 192 on the ejection spring receiving protrusion 182 side at a right angle to the bracket 162. The stopper 172 will be described later.

Next, the spring 168 will be described.
The spring 168 has a function of biasing the swing lever 166 in a predetermined direction with a predetermined force. Specifically, it has a function of biasing the ejection roller 116 in the opposite direction to the fixed guide body 114. The spring 168 is a concept that includes members having a similar function, such as rubber and a gas spring.
In this embodiment 1, one end of the spring 168 is engaged with the ejection spring receiving projection 182 and the other end with the spring engaging portion 210, and ultimately a rotational force is applied to the ejection roller 116 in a direction approaching the fixed guide body 114. The spring 168 is set to have a smaller elastic force than the tension spring 156, and when the disc delivery device 100 is normally operating, the disc C is ejected by the elastic force of the tension spring 156.

Next, the stopper 172 will be described.
The stopper 172 has a function of preventing the swing lever 166 from turning due to the spring 168, and of restricting the distance between the ejection roller 116 and the fixed guide body 114 to a predetermined distance. In other words, the stopper 172 has a function of receiving the abutment piece 211 while cushioning it by surface contact, and stopping it at a predetermined position.
In the first embodiment, the stopper 172 is formed in a ring shape from a resin that is substantially non-hydrolyzable, and is preferably an engineering plastic.
Engineering plastics have excellent mechanical strength, e.g., impact resistance, and therefore are highly durable against repeated blows from the abutment piece 211 of the oscillating lever 166. In addition, because they have a high flexural modulus, they have high shock absorption properties against the abutment piece 211 and have the advantage of little rebound, making them suitable for a stopper that receives the impact from the oscillating lever 166 in the disc body delivery device 100.
In this specification, the term "engineering plastic" refers to a material that has a tensile strength of 50 MPa or more at room temperature and a flexural modulus of 2.4 GPa or more at room temperature, and is essentially not hydrolyzable in the present invention. Specifically, in addition to polyacetal resin, polycarbonate resin, modified polyphenylene ether resin, polyamide resin, or ultra-high molecular weight polyethylene resin are assumed to be resins that are essentially not hydrolyzable and can be used in the present invention. "Imparting substantially no hydrolysis" means that the material is not sticky even when used in high humidity.

Next, the stopper 172 will be described mainly with reference to FIGS.
In the first embodiment, the stopper 172 is made of polyacetal resin, has a predetermined thickness, for example, 1 mm, a predetermined diameter, for example, 8 mm, has a through hole 218 formed in the center, and is formed in a circular ring shape as a whole. The through hole 218 is formed by a cylindrical hole 218P and a conical hole 218C connected to the cylindrical hole 218P. The cylindrical hole 218P has a diameter of about 4 mm, and the conical hole 218C is a conical hole having an angle A of 90 degrees inclined at an angle of 45 degrees to the left and right with respect to the center line CL.

表１において、一部のサイクルにおける評価を省略してあり、当該サイクルにおける評価は、前回の評価に対し、変化がない状態である。
評価「○」は、外観観察において、試料の表面に異常が見られない状態である。表面に異常が見られない状態とは、粘性物も無く、復元性も良く、ひび割れや崩落がない状態である。この場合の硬度を測定したところ、初期と比べ１００～７５％の範囲内にあった。試験が進めば、劣化が進行するが、硬度が初期値に比べて７５％以上であれば、試料は、外観的にも機能的に問題が生じなかった。粘性物とは、試料が水と反応し、加水分解される過程で生成される中間生成物や加水分解後の生成物であり、粘性のある物質である。復元性が良い状態とは、デュロメータで試料を押した場合、押し跡が残らない状態である。

また、試料がストッパ172として使用できるか否かを判断すると、下記の様になる。
評価「○」の場合は、好適に、使用できる。
評価「△」の場合は、問題を起こす場合があるので、使用できない。
評価「×」の場合は、問題を起こすので、使用できない。
上記より、実施例１における、ポリアセタール樹脂によって製造したストッパ172が加水分解による悪影響が長期に亘り生じないので最も適した材料であると言える。 Next, a test example of the stopper 172 made of polyacetal will be described.
The test was carried out by subjecting the samples to a temperature and humidity cycle test in which a high temperature and high humidity state and a low temperature and low humidity state were repeatedly performed, and the samples were evaluated by measuring their hardness and observing their appearance after each cycle.
The temperature and humidity cycle test is a test in which the following high temperature and high humidity environment and low temperature and low humidity environment are repeatedly performed to accurately produce condensation and dry states in the sample, thereby conducting an accelerated evaluation of hydrolysis.
Specifically, the temperature and humidity cycle test was carried out by placing a sample in a test room and repeating the following steps 1 to 4 as one cycle.
1. The high temperature and high humidity environment is left in an environment with a temperature of 60°C and a humidity of 90% for 3 hours.
2. Leave the device for one hour before switching from a high temperature, high humidity environment to a low temperature, low humidity environment.
3. The low temperature and low humidity environment is left in an environment with a temperature of -20°C and humidity of 0% for 3 hours.
4. Leave the device for one hour before switching from the low temperature, low humidity environment to the high temperature, high humidity environment.
The shape of the sample used in the test is shown in Fig. 9. The material of the sample in Comparative Example 1 is an ester-based urethane rubber containing an ester bond in the main chain. The material of the sample in Comparative Example 2 is an ether-based urethane rubber containing an ether bond in the main chain. The material of the sample in the example is a polyacetal resin.
Comparative Example 1: Ester-based urethane rubber, initial hardness 80
Comparative Example 2: Ether-based urethane rubber, initial hardness 80
Example 1: Polyacetal resin, initial hardness 90
The hardness was evaluated by measuring the hardness with a type A durometer that satisfies the conditions of the measuring instrument specified in JIS K 6253, and determining the rate of change from the initial value.
The appearance of the stopper was observed, and the surface condition, for example, the presence or absence of viscous matter, the presence or absence of cracks, the restoration of dents, and the presence or absence of collapse at corners were observed.
The test results are shown in Table 1 below.

In Table 1, the evaluations in some cycles are omitted, and the evaluations in those cycles are unchanged from the previous evaluation.
The evaluation "○" indicates that no abnormality is found on the surface of the sample in the visual observation. A state in which no abnormality is found on the surface means that there is no viscous matter, the recovery is good, and there is no cracking or collapse. When the hardness was measured in this case, it was within the range of 100 to 75% compared to the initial value. As the test progresses, deterioration progresses, but if the hardness is 75% or more compared to the initial value, the sample does not have any problems in terms of appearance or function. Viscous matter is an intermediate product generated during the hydrolysis process when the sample reacts with water, or a product after hydrolysis, and is a viscous substance. A state in which recovery is good means that no impression is left when the sample is pressed with a durometer.
A rating of "△" indicates that, upon visual observation, there is a viscous substance on the surface of the sample, or that a mark left by pressing with the pin of the durometer is visible. When the hardness of this case was measured, it was within the range of 74-58% compared to the initial value. If the deterioration of the sample progresses and the hardness falls within this range, the sample may have problems in appearance and may also have problems in functionality. A state in which a mark left by pressing with a pin is a state in which, when the sample is pressed with a durometer, the pressed mark does not return to its original shape immediately and a mark is left.
The evaluation "x" indicates that there is an abnormality on the surface when observed from the appearance. An abnormality on the surface of the sample is, for example, a state in which cracks appear on the surface or collapse is observed at the corners. When the hardness in this case was measured, it was within the range of 57 to 43% compared to the initial value. The deterioration of the sample progresses, and problems arise in terms of appearance and functionality. Problems arise when the hardness falls below 57% compared to the initial value.
In the appearance observation of cycle 9 of Comparative Example 1, a viscous substance was observed on the surface of the sample, and therefore the sample was rated as "Δ".
In cycle 12 of Comparative Example 1, a viscous substance was observed on the surface of the sample, and when the sample surface was brought into contact with the contact piece 211, the contact piece 211 adhered to the sample, and a load was generated to peel it off, so the evaluation was given as "X".
In the appearance observation of cycle 15 of Comparative Example 2, a pin mark remained, which resulted in poor recovery and deterioration of mechanical strength, and the evaluation was given a "△" grade. Since ether-based urethane rubber does not have an ester bond, it is considered to be difficult to hydrolyze, but deterioration progresses little by little, and the strength is decreasing. Although it is not certain, the cause may be cleavage of the urethane bond or hydrolysis of the urethane bond.
Moreover, when it is determined whether or not the sample can be used as the stopper 172, the following occurs.
If the evaluation is "◯", it can be suitably used.
If the rating is "△", it may cause problems and cannot be used.
If the rating is "x", it will cause problems and cannot be used.
From the above, it can be said that the stopper 172 made of polyacetal resin in the first embodiment is the most suitable material because it is not adversely affected by hydrolysis for a long period of time.

The stopper 172 is fixed to the stopper support piece 184 by the countersunk screw body 222. The end face of the stopper 172 on the cylindrical hole 218P side is placed against the stopper support piece 184, and the screw part 222S of the countersunk screw body 222 is passed through the conical hole 218C, the cylindrical hole 218P, and the mounting hole 224 formed in the stopper support piece 184, and is fixed by a nut 226 screwed into the screw part of the countersunk screw body 222. By tightening the nut 226, the screw part 222S is moved in the axial direction, and the conical surface 222C of the screw head 222H of the countersunk screw body 222 is pressed against the conical hole 218C. As a result, in the stopper 172, the impact part 176 against which the abutment piece 211 of the swing lever 166 abuts is formed into a circular ring-shaped surface. By making the stopper 172 ring-shaped, the impacted portion 176 becomes a ring-shaped surface, reducing the area and facilitating manufacturing. The stopper 172 is made of resin and has a certain degree of elasticity, so the reaction force of the tightening by the nut 226 acts from the conical surface of the conical hole 218C to the conical surface 222C of the countersunk screw body 222, and the force acts in the axial direction of the countersunk screw body 222. This causes a force in the thrust direction to act between the female thread of the nut 226 and the male thread of the screw portion 222S, preventing the nut 226 from loosening.

Next, the position adjustment unit 174 will be described.
The position adjustment unit 174 has a function of adjusting the position of the ejection roller 116 relative to the fixed guide body 114. In this embodiment 1, the position adjustment unit 174 is composed of an arc-shaped long hole 188 centered on the axis of the lever shaft hole 186 and a set screw 228. The set screw 228 is passed through the arc-shaped long hole 188 and screwed into the back surface of the base 106, and has a function of holding the bracket 162 in a fixed state by frictional force.

Next, a method for attaching the ejection device 113 to the rear surface of the base plate 106 will be described.
The ejection device 113 is fixed at a predetermined position by inserting the positioning shaft 200 protruding from the back surface of the base 106 into the positioning hole 194, bringing the upper surface of the bracket 162 into close contact with the back surface of the base 106, and screwing the set screw 228 into the base 106. The predetermined position means that the distance between the ejection roller 116 and the fixed guide body 114 is set to a position suitable for the diameter of the disk body C. When adjusting the position of the ejection roller 116, the set screw 228 is loosened, the bracket 162 is rotated around the positioning shaft 200, and the set screw 228 is tightened again at an appropriate position.

Since the stopper 172 is hit by the contact piece 211 many times each time, it is necessary for the stopper 172 to have high durability to prevent defects such as cracks. Therefore, an example of a manufacturing method of the stopper 172 in this embodiment 1 will be described with reference to FIG.
As shown in FIG. 1A, in this embodiment 1, the material of the stopper 172 is a round bar material 234 made by drawing polyacetal resin to a standardized predetermined diameter. Engineering plastics are more difficult to injection mold than general-purpose resins, and require temperature control of the mold. Due to poor temperature control, etc., the resins may not adhere to each other at the joining part of the resins, resulting in a boundary (weld), and cracks may occur from the boundary. However, a drawn round bar material is preferable because it does not produce such a boundary and there is no risk of cracks from the boundary. In other words, it is preferable to use a round bar material 234 made of polyacetal resin with a standardized outer diameter and length.
Next, as shown in FIG. 1B, a round bar material 234 is attached to the chuck of a lathe, and a small diameter drill 236 is placed against the end face of the round bar material 234 to drill a circular hole 238 that will become the cylindrical hole 218P in the center.
Next, as shown in FIG. 2C, a large diameter drill 242 is placed against the end face of the circular hole 238 to perform countersinking, forming a conical hole 244 of a predetermined depth that will become the conical hole 218C.
Next, as shown in FIG. 2D, the round bar material 234 is cut off by a cut-off tool 240 at a predetermined length LS (corresponding to the thickness of the stopper 172) from the end face of the round bar material 234, thereby forming the stopper 172.

Next, the disk sensor 230 will be described mainly with reference to FIG. 2 or FIG.
The disk sensor 230 has a function of detecting the disk C ejected by the fixed guide 114 and ejection roller 116, and is disposed in relation to the path of movement of the ejected disk C, and may employ a photoelectric sensor, a metal sensor, or the like. In this embodiment 1, a metal sensor is used. The disk sensor 230 includes, for example, a sensor bracket 246, a U-shaped sensor body 248, a sensor coil 250, and a detection circuit (not shown).
The sensor body 248 is formed in a U-shape by an upper horizontal bar 248U and a lower horizontal bar 248L arranged vertically at a predetermined interval, and a pillar 248P connecting one end of the upper horizontal bar 248U and the lower horizontal bar 248L, and the disk C ejected by the fixed guide body 114 and the ejection roller 116 passes through a gap 252 between the upper horizontal bar 248U and the lower horizontal bar 248L through the sensor coil 250. The ejection of the disk C is detected by detecting a change in the current flowing through the sensor coil 250 due to the metal disk C. The sensor body 248 is fixed to the base 106 by a sensor bracket 246.

Next, the operation of the first embodiment will be described.
The disks C stored in the coin storage container 102 are stirred by the rotation of the rotating disk 110 and assume various positions, so that they drop one by one into the through holes 126 (126A to 126E). The disks C that have fallen into the through holes 126 come into surface contact with the base 106, are pushed by the inner pushing portion 128i, and are guided by the outer peripheral surface of the peripheral surface guide wall 118 while being carried around the coin passage 136 by the rotating disk 110 (FIG. 3).
When the disk body C is pushed toward the regulating body 112, it is first guided by the inner regulating body 112i toward the outlet opening 122, in other words, in the radial direction of the rotating disk 110 (Figure 3), and then guided by the outer regulating body 112e in the radial direction of the rotating disk 110 (Figure 4).

As a result, a part of the circular arc circumferential surface of the disk body C is guided by contacting the fixed guide body 114, the disk body C is guided as a whole toward the ejection roller 116, and the other side of the circular arc circumferential surface comes into contact with the ejection roller 116. In this process, the pushing portion 128 of the disk body C moves from the inner pushing portion 128i to the outer pushing portion 128e. The disk body C is further pushed in the radial direction of the rotating disk 110 by the outer pushing portion 128e, so that the ejection roller 116 is separated from the fixed guide body 114. Until the ejection roller 116 is moved by the disk body C, it is kept in a stationary state with a predetermined distance less than the diameter of the disk body C from the fixed guide body 114, and the abutment piece 211 of the swing lever 166 is in surface contact with the struck portion 176 of the stopper 172 by the elastic force of the spring 168 and is pressed against it.
When the ejection roller 116 is moved by the disk body C, the swing lever 166 is rotated clockwise in Fig. 4 against the elastic force of the spring 168. This clockwise rotation of the swing lever 166 causes the abutment piece 211 to move away from the stopper 172 (the struck portion 176).

When the disc body C is pushed between the fixed guide body 114 and the ejection roller 116 by the outer pushing portion 128e, the ejection roller 116 is moved in a direction away from the fixed guide body 114 against the elastic force of the spring 168, and then, as shown in FIG. 4, immediately after the center of the disc body C passes the straight line L connecting the tangent point P1 between the disc body C and the fixed guide body 114 and the tangent point P2 between the disc body C and the ejection roller 116, the fixed guide body 114 and the ejection roller 116 each come into contact with the arcuate surface on the rear side in the traveling direction of the disc body C, so that the elastic force of the spring 168 moves the ejection roller 116 toward the fixed guide body 114, and the ejection roller 116 is ejected in a direction away from the rotating disk 110. As the ejection roller 116 moves toward the fixed guide body 114, the swing lever 166 is rotated counterclockwise in FIG. 4, and the abutment piece 211 collides with the struck portion 176 of the stopper 172, stopping the rotation and coming to a standstill. Since resin has a lower hardness than metal, the micro-vibrations caused by the rebound converge quickly. In addition, since the density is significantly lower than metal, the impact sound is also significantly reduced. In addition, since the resin is not substantially hydrolyzed, it has the advantage of not becoming sticky and not causing false detection or ejection failure even when used under high humidity conditions.

Next, a second embodiment will be described with reference to FIG.
The second embodiment is an example in which a configuration for enhancing the durability of the stopper 172 in the first embodiment is added. The same components as those in the first embodiment are given the same reference numerals and their explanations are omitted, and only different configurations will be explained.
This is an example in which a deformation prevention ring 256 is provided so as to surround the outer periphery of the stopper 172. The deformation prevention ring 256 of the second embodiment has an inner peripheral surface that is in close contact with the outer peripheral surface of the stopper 172, and has a function of preventing radial deformation of the stopper 172. The deformation prevention ring 256 in this embodiment (hereinafter referred to as the "second deformation prevention ring 2562" for convenience) is a cylindrical ring body having a predetermined diameter and height. In addition, the height H2 of the second deformation prevention ring 2562 is set lower than the height (thickness) H3 of the stopper 172. As a result, the abutment piece 211 abuts against the impacted portion 176 of the stopper 172, suppressing radial deformation of the stopper 172 due to multiple impacts by the abutment piece 211, and improving durability. In addition, it is preferable that the height H2 of the second deformation prevention ring 2562 is set higher than the height H1 of the screw head 222H of the countersunk screw body 222. With this, even if the stopper 172 is deformed and the height H3 decreases, the abutment piece 211 abuts against the deformation prevention ring 256, thereby preventing impact to the head of the flat head screw body 222. The second deformation prevention ring 2562 can be fixed to the stopper support piece 184, or press-fitted into the stopper 172. The second deformation prevention ring 2562 is preferably made of a metal, which has superior mechanical properties to resin.

Next, a third embodiment will be described with reference to FIG.
Example 3 is an example in which a deformation prevention ring 256 (hereinafter referred to as a "third deformation prevention ring 2563" for convenience) is formed on the stopper support piece 184 instead of the deformation prevention ring 256 (second deformation prevention ring 2562) in Example 2. The same parts as in Example 1 are given the same reference numerals and their explanations are omitted, and different configurations will be explained.
The third deformation prevention ring 2563 is a circular ring-shaped raised portion formed by drawing or the like on the stopper support piece 184, with a cross section in a mountain shape, and the portion surrounded by the third deformation prevention ring 2563 is formed into a circular flat portion 258. The lower surface of the stopper 172 is in contact with the flat portion 258 and fixed by the countersunk screw body 222. This allows the lower end of the stopper 172 to be fitted into the third deformation prevention ring 2563. Therefore, when the lower end of the stopper 172 deforms to bulge, it is restricted by the third deformation prevention ring 2563, which has the advantage of suppressing the deformation of the stopper 172. The third deformation prevention ring 2563 may be fixed by brazing or the like to the stopper support piece 184.

Next, a fourth embodiment will be described with reference to FIG.
The fourth embodiment is a modified example of the deformation prevention ring 256 described in the second embodiment. The same parts as those in the second embodiment are given the same reference numerals, and the description is omitted, and the different configurations are described. The deformation prevention ring 256 of the fourth embodiment (hereinafter referred to as the "fourth deformation prevention ring 2564" for convenience) has a circular ring portion 262 having a predetermined height and a ring-shaped bottom portion 264 continuous with the bottom of the circular ring portion 262, and is formed in a bottomed pan shape having a bottom hole 266 of a predetermined diameter smaller than that of the circular ring portion 262. The stopper 172 is formed in a stepped cylindrical shape with a large diameter on the conical hole 218C side and a small diameter on the cylindrical hole 218P side in accordance with the shape of the fourth deformation prevention ring 2564. This allows the stopper 172 made of resin to be press-fitted into the circular ring portion 262 to integrate the stopper 172 and the fourth deformation prevention ring 2564, which has the advantage of improving durability as in the second embodiment and improving handleability.

Next, a fifth embodiment will be described with reference to FIG.
The fifth embodiment is a modified example of the deformation prevention ring 256 described in the second embodiment. The same parts as those in the second embodiment are denoted by the same reference numerals, and the description thereof will be omitted, and the different configurations will be described. The deformation prevention ring 256 of the fifth embodiment (hereinafter referred to as the "fifth deformation prevention ring 2565" for convenience) is composed of a circular ring portion 262 and a circular flange portion 268 extending in the circumferential direction from the lower end of the circular ring portion 262. The stopper 172 may be in the ring shape described in the first embodiment, or in the disk shape as shown in FIG. 15. The lower end of the stopper 172 is press-fitted and fixed into the circular ring portion 262. The fifth deformation prevention ring 2565 is fixed to the stopper support piece 184 by a plurality of screws 270 and washers 272 penetrating the flange portion 268, and a nut 274. The bottom surface of the stopper 172 is in surface contact with the surface of the stopper support piece 184.
In the fifth embodiment as well, the stopper 172 can be prevented from becoming sticky.
