The roller is moved by being urged by a second elastic member hung between the hook portion fixed to the base body and sandwiching the first coin between the first guide and the roller. When the interval is less than a predetermined size, the first movable member does not swing, only the second movable member swings against the urging force of the first elastic member, and the first movable member swings. When a second coin having a diameter larger than that of the coin is sandwiched between the first guide and the roller, the roller moves and the distance is equal to or larger than a predetermined size, the first movable member is the second. A coin payout device that swings against the urging force of an elastic member is known (see, for example, Patent Document 4).

JP 2001-134800 (Figs. 1 to 3, paragraphs 0011, 0012) Japanese Patent Application Laid-Open No. 2010-131122 (Figs. 1 to 11, Paragraph 0007) JP 2014-174720 (Figs. 1 to 17, paragraph 0007) JP-A-2018-012864 (Figs. 1-20, paragraph 0014, 0068)

In the first prior art, the coin is sandwiched between a guide member and a payout roller attached to an arm urged by a spring and ejected, the arm is blocked by a stopper from moving, and the payout roller and the guide member A predetermined interval is maintained between. The stopper is made of an elastic body such as rubber so that the impact at the time of contact is alleviated.

In the fourth prior art, the coin is sandwiched and ejected between a roller attached to a second movable member urged by a fixing member and an elastic member, and the second movable member is blocked from moving by an abutting body. And a predetermined distance is maintained between the fixing member and the roller. There is no mention of the material of the abutment body.

In the disk body sending device, the swing lever to which the ejection roller for ejecting the disk body such as coins is attached is brought into contact with the elastic body as a stopper to reduce the striking sound and improve the durability. As the elastic body, urethane rubber having better mechanical properties than rubber, in other words, durable, is usually used in consideration of durability, availability, and cost. Urethane rubber includes ether type and ester type.
Ether-based urethane rubber does not cause hydrolysis, but its mechanical strength is inferior to that of ester-based urethane rubber, in other words, it is inferior in durability, so that it is hit several million times or more in a circular medium delivery device. It is not suitable as a stopper that receives the impact of the ejection roller.
Ester-based urethane rubber has excellent mechanical strength and is therefore highly durable, and is more suitable than ether-based urethane rubber. However, since ester urethane rubber hydrolyzes, it is not suitable for long-term use in a high humidity atmosphere. The reason will be explained below.
The disk sending device is usually installed in a vending machine or a currency exchange machine and is used as a coin payout device, so that it is used in a harsh natural environment. 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 does not easily leak from the housing, so that hydrolysis may be promoted.
As described above, since the ester urethane rubber is hydrolyzed, when it is used under high humidity conditions, the hydrolysis may cause stickiness and stickiness. If the stickiness of the stopper occurs on the stopper of the disk body delivery device, there is a concern that the disk body cannot be smoothly transmitted.

This concern is explained with reference to Figure 16.
In FIG. 16, C is a disk body, 12 is a flat plate-shaped substrate, and 14 is a pushing piece 16 projecting to the lower surface while separating the disk body C one by one (inner pushing piece 16i, outer pushing piece 16e). A rotating disk that is pushed in the circumferential direction or the radial direction by 18 is a C-shaped peripheral guide body that guides the peripheral surface of the disk body C that is pushed by the inner push piece 16i and the outer push piece 16e, and 20 is. A delivery opening in which a part of the peripheral surface of the peripheral surface guide 18 is opened, 22 is a fixed guide body held in a substantially fixed state at one end of the outlet opening 20, and 24 is a ejection roller. The ejection roller 24 has an arcuate slot (not shown) formed in the base 12 from the tip of a swing lever 28 rotatably provided around a support shaft 26 projecting to the back surface side of the base 12. It is rotatably supported by the tip of the shaft 30 that projects toward the surface side of the base 12 via the base 12. The swing lever 28 is urged by a spring 32, which is an elastic body, so as to approach the fixed guide body 22 side. A stopper 38 made of urethane rubber is fixed to the swing lever 28 side of the stopper piece 34 protruding downward from the back surface of the base 12. The contact portion 40 of the swing lever 28 is restricted from moving by the stopper 38. That is, the ejection roller 24 is blocked from moving by the stopper 38, and the distance between the ejection roller 24 and the fixed guide body 22 cannot be closer than a predetermined distance smaller than the diameter of the disk body C.
Therefore, when the disk body C is not sent out, the contact portion 40 of the swing lever 28 is pressed against the stopper 38 by the elastic force of the spring 32 with a predetermined force.

When the disk body C is sent out, the disk body C falls between the push pieces 16 through the through holes (not shown) due to the rotation of the rotating disk 14, and is separated into pieces, and the peripheral guide body 18 is separated. Reach the exit opening 20 while being guided by.
Initially, the disk body C is pushed by the pushing piece 16 in the radial direction of the rotating disk 14 while being guided by the fixed guide body 22 on one side of the rear arc surface on the front side in the traveling direction and by the ejection roller 24 on the other side. Be moved. As a result, the ejection roller 24 is moved away from the fixed guide body 22. By the movement of the ejection roller 24, the swing lever 28 is rotated clockwise in FIG. 16, so that the contact portion 40 is separated from the stopper 38. When the fixed guide body 22 and the ejection roller 24 are in contact with the front arc surface in the traveling direction of the disk body C, the fixed guide acting on the disk body C by the elastic force applied by the spring 32 to the ejection roller 24. The resultant force from the body 22 and the ejection roller 24 is the direction in which the disk body C is returned toward the center of the rotating disk 14. However, immediately after the center of the disk body C passes through the straight line connecting the contact point between the disk body C and the fixed guide body 22 and the contact point between the disk body C and the ejection roller 24, the fixed guide body 22 and the ejection roller 24 Since it comes into contact with the rear arc surface of the disk body C, the resultant force acting on the disk body C from the fixed guide body 22 and the ejection roller 24 acts in the direction away from the rotating disk 14, so that the bullet of the spring 32 Due to the force, the swing lever 28 is pulled toward the fixed guide body 22, and the ejection roller 24 pushes the rear peripheral surface of the disk body C and ejects it vigorously in a certain direction. The ejected disk body C is detected by the metal sensor 42.
If the stopper 38 is not sticky, the swing lever 28 can also rotate as the ejection roller 24 moves. Therefore, the elastic force of the spring 32 brings the disk body C closer to the fixed guide body 22 side at a predetermined speed, and the disk body C is sent out at a predetermined speed and at a predetermined timing each time.

However, when the stopper 38 becomes sticky due to hydrolysis, the contact portion 40 cannot be immediately separated due to the adhesive force of the stopper 38. In other words, when the arc surface on the front side in the traveling direction of the disk body C comes into contact with the ejection roller 24, the swing lever 28 (contact portion 40) immediately separates from the stopper 38 due to the adhesive force due to the stickiness of the stopper 38. The contact portion 40 is attached to the stopper 38 until the elastic force of the spring 32 becomes equal to or more than a predetermined value. Then, when the elastic force of the spring 32 exceeds a predetermined value, the contact portion 40 (swing lever 28) momentarily separates from the stopper 38. As a result, the inertial force of the swing lever 28 and the ejection roller 24 increases. For example, the swing lever 28 overruns and rotates from the normal rotation position, and then approaches the fixed guide body 22. Will be moved. Since the swing lever 28 is rotated more than usual, the spring 32 is stretched more than usual. As a result, the elastic force of the spring 32 is increased, and the ejection roller 24 is moved to the fixed guide 22 side at a higher speed than usual. As a result, the ejection speed of the disk body C is increased, and the metal sensor 42 may not have a sufficient detection time width, resulting in erroneous detection. Further, when the ejection roller 24 is moved at a higher speed than usual, the ejection direction of the disk body C becomes different from the normal direction, which may cause an ejection failure.

The operating environment and operating state of the disk body sending device in vending machines and the like are extremely diverse depending on the products provided, the installation location, the price setting, and the like. For example, in the case of frequent operation, even if hydrolysis occurs in the stopper 38, the contact portion 40 and the stopper 38 are separated from each other before the time until the adhesiveness increases has elapsed. , The above-mentioned concerns rarely occur in reality. On the other hand, depending on the installation location of the vending machine or the like, if the operation frequency of the disk body delivery device is low, it may not operate for one day or more, for example.
Then, since the contact portion 40 is pressed against the stopper 38 for a long time, when the stopper 38 is hydrolyzed, the degree of adhesion is increased due to the stickiness of the stopper 38, and the above-mentioned false detection or ejection failure may occur.
In addition, even if it is a short time, if hydrolysis is progressing, the above-mentioned defect may occur.

Next, the base 104 will be described.
The base 104 has a function in which the base 106 is mounted like a ceiling and also has a function of incorporating a rotation drive device and a control unit of the rotation disk 110. In the first embodiment, the front side F is low and the rear side R is low. It is a tall, side-viewing platform-shaped channel type, and as a result, the upper surface 104U is formed on a slope that descends forward from the posterior R to the anterior F. However, the upper surface 104U can also be formed horizontally.

Next, the base 106 will be described with reference to FIGS. 1 and 2.
The base 106 has at least a function of guiding the lower surface of the disk body C that is rotated by the rotating disk 110. In the first embodiment, the base 106 is a rectangular flat plate having a predetermined thickness fixed to the upper surface 104U which is inclined forward and downward of the base 104. In the first embodiment, it is formed in a vertically long rectangular shape in order to guide the disk body C pushed by the rotating disk 110 and to arrange the fixed guide body 114 and the ejection roller 116. However, as long as the base 106 has the same function, its shape and the like do not matter.

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

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

Next, the exit opening 122 will be described mainly with reference to FIG.
In the outlet opening 122 of the first embodiment, the lower side of the base 106 in the peripheral surface guide wall 118 in the inclined direction is opened with a predetermined length, and a space d is formed by the left end portion 118L and the right end portion 118R thereof. ..

Arranged in the container bottom hole 117 of the container 102, the push portion 128 at the lower end is rotated at a predetermined speed inside the peripheral surface guide wall 118. In the first embodiment, the rotating shaft 130 is rotated via the speed reducer 133 by an electric motor 131 attached to the back surface side of the base 106. Therefore, the axes of the rotating shaft 130 and the rotating disk 110 also coincide with the axis CS. Further, the peripheral surface guide wall 118 is located outside the pushing portion 128. Since the rotating shaft 130 is tilted with respect to the base 106, the rotating disc 110 is also tilted forward and rotated in a plane parallel to the base 106. In other words, the base 106 and the rotating disk 110 are arranged in parallel with a predetermined gap. The gap is the distance between the lower end of the pushing portion 128 formed on the back surface of the rotating disk 110 (disk body 124) and the upper surface of the base 106, and the lower end of the pushing portion 128 does not come into contact with the base 106. When the thickest disk body C expected to be used slides on the base 106, a slight gap is formed between the upper surface of the disk body C and the back surface of the disk body 124.

A weight-shaped stirring portion 132 is formed around the rotating shaft 130 on the upper surface side of the disk body 124, and the disk bodies C bulkly piled up in the coin holding container 102 are stirred when the rotating disk 110 is rotated.

Regulate to rotate at intervals of one or less. A sheet made of a low friction body can be interposed between the lower end surface of the gap restricting portion 134 and the base 106 in order to reduce frictional resistance.

Next, the through hole 126 which is the separation portion 125 will be described.
The separation unit 125 has a function of separating the disk bodies C bulked in bulk in the coin holding container 102 one by one. In the first embodiment, the separation portion 125 is a circular through hole 126 that vertically penetrates the disk main body 124 at the eccentric position of the disk main body 124. In the first embodiment, five through holes 126 (126A to 126E) are formed. Therefore, for convenience, the numbers 126 are displayed with the alphabets A to E, and the explanations are given individually.

In the first embodiment, there are five circular through holes 126A to 126E formed at equal intervals at the eccentric position of the disk main body 124. The diameter of the through hole 126 may be set to a diameter at which the target disk body C having the maximum diameter can smoothly fall so that it can correspond to a plurality of disk bodies C having two or more, and the specific disk body C is the most. It may have a dedicated diameter that allows it to fall smoothly and be processed.
When formed in this way, the edge of the gap restricting portion 134 becomes a petal shape.
On the back surface between the adjacent through holes 126A to 126E of the disk body 124, a swept wing-shaped pushing portion 128 (128A to 128E) extending toward the peripheral edge is formed.

Next, the pushing unit 128 will be described.
The pushing portion 128 is a ring-shaped coin passage 136 formed between the gap restricting portion 134 and the peripheral surface guide wall 118 for the disk body C that has fallen into the through holes 126A to 126E due to the rotation of the rotating disc 110. It has a function of pushing FIG. 3). In the first embodiment, the pushing portion 128 is a protrusion protruding downward on the lower surface of the disk main 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 explanation, five push parts 128 (128A to 128E) are formed, so for convenience, the numbers 128 are displayed with the letters A to E, and when explaining individually, the numbers are displayed. If you don't need a separate explanation, use only the number 128 as a generic term. Since the configurations of the push-pushing portions 128A to 128E are all the same, a description will be given with reference to FIG. 4 on behalf of the push-pushing portion 128A.

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

Therefore, between the outer pushing portion 128e and the inner pushing portion 128i, an arc-shaped outer escape groove 138e centered on the axial center CS of the rotating disk 110 is formed so that the outer ruler 112e can pass through.
It is preferable that the rear end of the rotating disk 110 of the inner pushing portion 128i in the normal rotation direction is formed flush with the peripheral edge of the through hole 126B. This is to prevent the disk body C from rampaging (irregular movement) by suppressing the amount of movement of the disk body C that has fallen into the through hole 126A as much as possible, and as a result, prevent unexpected troubles.
Further, the front surface of the inner pushing portion 128i is formed so as to extend in the radial direction from the axial center SC. When the disk body C comes into contact with the peripheral surface guide wall 118 and is guided while being guided, the disk body C is pushed by the inner pushing portion 128i.

In the first embodiment, the stopper 172 is formed in a ring shape by a resin that does not substantially hydrolyze. As the resin, engineering plastics are preferable.
Since engineering plastics are excellent in mechanical strength, for example, impact, they are highly durable against impacts received from the contact piece 211 of the repetitive swing lever 166, and also have a high flexural modulus, so that they absorb the impact on the contact piece 211. Since it has a high property and has an advantage that the amount of rebound is small, it is suitable as a stopper for receiving the impact of the swing lever 166 in the disk body delivery device 100.
In the present specification, the engineering plastic needs to maintain 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 further, in the present invention, it is required to have substantially no hydrolyzability. be. Specifically, as the resin that can be used in the present invention and does not substantially hydrolyze, a polycarbonate resin, a modified polyphenylene ether resin, a polyamide resin, or an ultra-high molecular weight polyethylene resin is assumed in addition to the polyacetal resin. Substantially non-hydrolyzable means that it is not sticky even when used in high humidity.

Next, the stopper 172 will be described mainly with reference to FIGS. 9 and 10.
In the first embodiment, the stopper 172 is formed of a polyacetal resin having a predetermined thickness, for example, 1 mm, a predetermined diameter, for example, 8 mm, a through hole 218 is formed in the center, and is formed in a circular ring shape as a whole. ing. 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 tilted at an angle of 45 degrees to the left and right with respect to the center line CL.

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.
In the test, a temperature / humidity cycle test was performed in which a high temperature and high humidity state and a low temperature and low humidity state were repeated for the sample, and the hardness of the sample was measured and the appearance was observed for each cycle for evaluation.
The temperature-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 generate the dew condensation state and the dry state in the sample, and to accelerate the evaluation of hydrolysis.
As for the specific contents of the temperature / humidity cycle test, the sample was placed in the test room, and the following steps 1 to 4 were repeated as one cycle.
1. In a high temperature and high humidity environment, leave it in an environment with a temperature of 60 ° C. and a humidity of 90% for 3 hours.
2. Leave it for 1 hour until switching from a high temperature and high humidity environment to a low temperature and low humidity environment.
3. In a low temperature and low humidity environment, leave it in an environment with a temperature of -20 ° C and a humidity of 0% for 3 hours.
4. Leave it for 1 hour until switching from a low temperature and low humidity environment to a high temperature and high humidity environment.
The shape of the sample used in the test is the shape shown in FIG. The material of the sample of Comparative Example 1 is an ester-based urethane rubber containing an ester bond in the main chain. As the material of the sample of Comparative Example 2, an ether-based urethane rubber containing an ether bond in the main chain was used. The material of the sample of the example is 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
As a method for evaluating hardness, the hardness was measured with a type A durometer satisfying the conditions of the measuring instrument specified in JIS K 6253, and the rate of change with respect to the initial value was obtained.
In the appearance observation, the appearance of the stopper was observed, and the surface condition, for example, the presence or absence of a viscous substance, the presence or absence of cracks, the resilience of dents, and the presence or absence of collapse of the corners were observed.
Table 1 below shows the test results.

In Table 1, the evaluation in some cycles is omitted, and the evaluation in the cycle is in a state where there is no change from the previous evaluation.
Evaluation "○" is a state in which no abnormality is found on the surface of the sample in the appearance observation. The state in which no abnormality is found on the surface is a state in which there is no viscous substance, the stability is good, and there is no cracking or collapse. When the hardness in this case was measured, it was in the range of 100 to 75% as compared with the initial stage. As the test progressed, deterioration progressed, but if the hardness was 75% or more of the initial value, the sample did not have any functional problems in appearance. The viscous substance is an intermediate product or a product after hydrolysis produced in the process of reacting the sample with water and being hydrolyzed, and is a viscous substance. The state with good resilience is a state in which no imprint remains when the sample is pressed with a durometer.
The evaluation "Δ" is a state in which an abnormality such as a viscous substance on the surface of the sample or a trace of pressing with a durometer pin remains in the appearance observation. When the hardness in this case was measured, it was in the range of 74 to 58% as compared with the initial stage. If the deterioration of the sample progresses and the hardness is in this range, the sample may have a problem in appearance and may have a problem in function. The state in which a trace of pressing with a pin remains is a state in which when the sample is pressed with a durometer, the trace of pressing does not return immediately and a mark remains.
The evaluation "x" is a state in which there is an abnormality on the surface in the appearance observation. The state in which the surface of the sample is abnormal is, for example, a state in which cracks appear on the surface or collapse is seen in the corners. When the hardness in this case was measured, it was in the range of 57 to 43% as compared with the initial stage. Deterioration of the sample progresses, and the sample has problems in appearance and function. Problems arise when the hardness is 57% or less compared to the initial hardness.
In the appearance observation of cycle 9 of Comparative Example 1, a viscous substance was observed on the surface of the sample, so the evaluation was set to “Δ”.
In cycle 12 of Comparative Example 1, a viscous substance was observed on the surface of the sample, and when the surface of the sample and the contact piece 211 were brought into contact with each other, the contact piece 211 adhered to the sample and a load was generated to peel it off. , The evaluation was set to "x".
In the appearance observation of the cycle 15 of Comparative Example 2, it was judged that the stability was deteriorated and the mechanical strength was deteriorated because the trace of pressing with the pin remained, and the evaluation was set to “Δ”. Since ether-based urethane rubber does not have an ester bond, it is considered that it is difficult to be hydrolyzed, but the deterioration gradually progresses and the strength decreases. Although it is not clear, the cause may be the cleavage of the urethane bond or hydrolysis in the urethane bond.
Further, when it is judged whether or not the sample can be used as the stopper 172, the result is as follows.
If the evaluation is "○", it can be preferably used.
If the evaluation is "△", it may cause a problem and cannot be used.
If the evaluation is "x", it causes a problem and cannot be used.
From the above, it can be said that the stopper 172 manufactured of the polyacetal resin in Example 1 is the most suitable material because the adverse effect of hydrolysis does not occur for a long period of time.

The stopper 172 is fixed to the stopper support piece 184 by the countersunk screw body 222. In the stopper 172, the end surface on the cylindrical hole 218P side is applied to the stopper support piece 184, and the threaded portion 222S of the countersunk screw body 222 is mounted from the conical hole 218C to the cylindrical hole 218P and the stopper support piece 184. It is fixed by a nut 226 that penetrates the hole 224 and is screwed into the threaded portion of the countersunk screw body 222. By tightening the nut 226, the threaded portion 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 into the conical hole 218C. As a result, in the stopper 172, the impacted portion 176 to which the contact piece 211 of the swing lever 166 comes into contact is formed on the circular ring-shaped surface. By making the stopper 172 ring-shaped, the impacted portion 176 becomes a ring-shaped surface, so that the area is reduced and manufacturing becomes easy. Since the stopper 172 is made of resin and has a predetermined elasticity, a force acts from the conical surface of the conical hole 218C to the conical surface 222C of the countersunk screw body 222 by the reaction force tightened by the nut 226. , A force acts in the axial direction of the countersunk head screw body 222. As a result, a force in the thrust direction acts between the female screw of the nut 226 and the male screw of the screw portion 222S, and the loosening prevention effect of the nut 226 can be obtained.

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

Next, a method of attaching the ejection device 113 to the back surface of the base 106 will be described.
The ejection device 113 inserts a positioning shaft 200 protruding from the back surface of the base 106 into the positioning hole 194, brings the upper surface of the bracket 162 into close contact with the back surface of the base 106, and screws the set screw 228 into the base 106. It is fixed in place. The predetermined position is to set the distance between the ejection roller 116 and the fixed guide body 114 to be a position suitable for the diameter of the disk body C. The position of the ejection roller 116 is adjusted by loosening the set screw 228, rotating the bracket 162 around the positioning shaft 200, and tightening the set screw 228 again at an appropriate position.

Since the stopper 172 is hit by the contact piece 211 an extremely large number of times each time, it is required to have high durability without causing problems such as cracking. Therefore, an example of the method for manufacturing the stopper 172 in the first embodiment will be described with reference to FIG.
As shown in FIG. 6A, in the first embodiment, the material of the stopper 172 is a round bar material 234 obtained by drawing out a 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, and due to poor temperature control, etc., the resins may not adhere to each other at the confluence of the resins and boundaries may occur (weld). , Cracks may occur starting from the boundary. However, the round bar drawing material is preferable because it does not generate such a boundary and there is no possibility of cracking from the boundary. In other words, it is preferable to use a round bar material 234 made of polyacetal resin having a standardized outer diameter and length.
Next, as shown in Fig. (B), the round bar material 234 is attached to the chuck of the lathe, the small diameter drill 236 is attached to the end face of the round bar material 234, and the circular hole 238 that becomes a cylindrical hole 218P in the center. To pierce.
Next, as shown in the figure (C), a large-diameter drill 242 is applied to the end face of the circular hole 238 and countersunk to form a conical hole 244 having a predetermined depth to be a conical hole 218C. ..
Next, as shown in the figure (D), the round bar material 234 is cut by the parting 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 to form the stopper 172. do.

Next, the disk body sensor 230 will be described mainly with reference to FIG. 2 or FIG.
The disk body sensor 230 has a function of detecting the disk body C ejected by the fixed guide body 114 and the ejection roller 116, and is arranged in relation to the movement path of the ejected disk body C, and is a photoelectric sensor and a metal. A sensor or the like can be adopted. In the first embodiment, 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 a pillar 248P connecting one end of the upper crossbar 248U and the lower crossbar 248L arranged vertically at predetermined intervals and the upper crossbar 248U and the lower crossbar 248L, and is formed in a U shape. The disk body C ejected by the fixed guide body 114 and the ejection roller 116 passes through the gap 252 between the lower crossbar 248L and the sensor coil 250 part. The change in the current flowing through the sensor coil 250 due to the metal disk body C is detected, and the ejection of the disk body C is detected. The sensor body 248 is fixed to the base 106 by the sensor bracket 246.

Next, the operation of the first embodiment will be described.
The disk body C held in the coin holding container 102 is agitated by the rotation of the rotating disk 110 and takes various postures, so that the disk body C falls into the through holes 126 (126A to 126E) one by one. The disk body C that has fallen into the through hole 126 comes into surface contact with the base 106 and is pushed by the inner pushing portion 128i, and the coin passage 136 is guided by the rotating disk 110 while being guided by the peripheral guide wall 118 on the outer peripheral surface. It is taken around (Fig. 3).
When the disk body C is pushed to the ruler body 112, it is first guided by the inner ruler body 112i toward the exit opening 122 side, in other words, in the radial direction of the rotating disk 110 (FIG. 3), and then the outer ruler body 112e. Guides the rotating disk 110 in the radial direction (FIG. 4).

As a result, a part of the arc peripheral surface of the disk body C abuts on the fixed guide body 114 and is guided, the disk body C is guided to the ejection roller 116 side as a whole, and the arc peripheral surface on the other side is the ejection roller. Contact with 116. In this process, the pushing portion 128 of the disk body C shifts from the inner pushing portion 128i to the outer pushing portion 128e. Since the disk body C is further pushed in the radial direction of the rotating disk 110 by the outer pushing portion 128e, 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 stationary at a predetermined interval equal to or smaller than the diameter of the disk body C with respect to the fixed guide body 114, and the contact piece of the swing lever 166. The 211 is brought into surface contact with the impacted portion 176 of the stopper 172 by the elastic force of the spring 168 and is in pressure contact with the stopper 172.
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. By rotating the swing lever 166 in the clockwise direction, the contact piece 211 is separated from the stopper 172 (the impacted portion 176).

When the disk 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 moves away from the fixed guide body 114 against the elastic force of the spring 168. After that, as shown in FIG. 4, the center of the disk body C crosses the straight line L connecting the contact point P1 between the disk body C and the fixed guide body 114 and the contact point P2 between the disk body C and the ejection roller 116. Immediately after that, the fixed guide body 114 and the ejection roller 116 each come into contact with the arc surface on the rear side in the traveling direction of the disk body C, so that the ejection force of the spring 168 causes the ejection roller 116 to come into contact with the fixed guide body 114. It is moved to the side and ejected in the direction away from the rotating disk 110. When the ejection roller 116 moves toward the fixed guide body 114, the swing lever 166 is rotated in the counterclockwise direction in FIG. 4, and the contact piece 211 collides with the hit portion 176 of the stopper 172 on the surface and rotates. Is stopped and becomes stationary. Since resin has a lower hardness than metal, micro-vibration due to bounce converges at an early stage. In addition, since the density is significantly lower than that of metal, the striking sound is also significantly reduced. Further, since it is a resin that does not substantially hydrolyze, there is an advantage that it does not become sticky, does not cause false detection, or does not cause defective ejection even when used under high humidity conditions.

Next, the 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 parts as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and different configurations will be described.
This is an example in which the deformation prevention ring 256 is provided so as to surround the outer circumference of the stopper 172. The deformation prevention ring 256 of the second embodiment has a function that the inner peripheral surface is in close contact with the outer peripheral surface of the stopper 172 and the deformation of the stopper 172 in the radial direction is prevented. The deformation prevention ring 256 (hereinafter, referred to as “second deformation prevention ring 2562” for convenience) in the second embodiment is a cylindrical ring body having a predetermined diameter and height. Further, 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 contact piece 211 comes into contact with the hit portion 176 of the stopper 172, and the deformation of the stopper 172 in the radial direction due to multiple hits by the contact piece 211 can be suppressed, and the durability can be improved. Further, 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. As a result, even if the stopper 172 is deformed and the height H3 is lowered, the contact piece 211 comes into contact with the deformation prevention ring 256, so that the head of the countersunk screw body 222 can be prevented from being hit. Because it can be done. 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 having excellent mechanical properties with respect to the resin.

Next, the third embodiment will be described with reference to FIG.
In the third embodiment, the deformation prevention ring 256 (second deformation prevention ring 2562) in the second embodiment is replaced with the deformation prevention ring 256 (hereinafter referred to as “third deformation prevention ring 2563” for convenience) in the stopper support piece 184. This is an example of the formation. The same parts as those in the first embodiment are designated by the same reference numerals, the description thereof will be omitted, and different configurations will be described.
The third deformation prevention ring 2563 is a circular ring-shaped raised portion having a circular ring shape formed by drawing the stopper support piece 184 into a chevron shape, and is surrounded by the third deformation prevention ring 2563. The site is formed in a circular flat portion 258. The lower surface of the stopper 172 is in contact with the flat portion 258 and is fixed by the countersunk screw body 222. As a result, the lower end of the stopper 172 is fitted into the third deformation prevention ring 2563. Therefore, when the lower end portion of the stopper 172 is deformed so as to bulge, it is limited by the third deformation prevention ring 2563, so that there is an advantage that the deformation of the stopper 172 is suppressed. The third deformation prevention ring 2563 may be fixed to the stopper support piece 184 by brazing or the like.

Next, Example 4 will be described with reference to FIG.
The fourth embodiment is a modification of the deformation prevention ring 256 described in the second embodiment. The same parts as those in the second embodiment are designated by the same reference numerals, the description thereof will be omitted, and different configurations will be described. The deformation prevention ring 256 of the fourth embodiment (hereinafter, referred to as “fourth deformation prevention ring 2564” for convenience) has a circular ring portion 262 having a predetermined height and a continuous ring shape at the bottom of the circular ring portion 262. It is formed in a bottomed flat pan shape having a bottom portion 264 and a bottom hole 266 having a predetermined diameter smaller than that of the circular ring portion 262. The stopper 172 is formed in a stepped cylindrical shape having 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. As a result, the resin stopper 172 can be press-fitted into the circular ring portion 262 to integrate the stopper 172 and the fourth deformation prevention ring 2564, so that the durability is improved and the handleability is improved as in the second embodiment. There is an advantage to do.

Next, the fifth embodiment will be described with reference to FIG.
The fifth embodiment is a modification of the deformation prevention ring 256 described in the second embodiment. The same parts as those in the second embodiment are designated by the same reference numerals, the description thereof will be omitted, and different configurations will be described.
