Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is installed in a slot machine, a money changer, an automatic vending machine for various products, or the like to pay out a required number of coins (including medals and other pseudo coins). The present invention relates to a reinforcing structure for a disc rotor for transferring coins in a hopper type coin payout device.

[0002]

2. Description of the Related Art A reinforcing structure for a disc rotor for coin transport in a hopper type coin payout device of this type is disclosed in Japanese Utility Model Laid-Open No. 38657/1990 and 18753/1994.
No. 3 and JP-A-10-240993 are proposed.

Of the latter two known inventions, each of the rear curved wing pieces (partition wall and coin feed piece) protruding from the back surface of the synthetic resin coin conveying disk rotor is
In contrast to being partially reinforced with a metal material, the former known device is the closest to the present invention in that the entire surface of the disc rotor (rotating body) for coin transport made of synthetic resin is reinforced with a metal material. It is thought that.

That is, in the construction of the Japanese Utility Model Laid-Open No. 2-38657, the upper side disk (3A) of the rotating body (3) is made of plastic-worked surface side contact portion (31) of the stainless steel plate,
The back surface side replenishing portion (32) of the thermoplastic is joined and integrated with an adhesive or the like, and the front surface side contact portion (31) withstands rolling contact and sliding contact of the medal (M). On the other hand, the back side replenishment section (32) is designed to reduce the weight.

Further, in order to reduce the weight of the rotating body (3), a ring-shaped plate portion (3B) made of the same plastic as the back side supplementing section (32) is attached to the back side of the upper side disc (3A) by an adhesive. It is also integrated as an accessory.

[0006]

However, according to the configuration of the above-mentioned known device, the ring-shaped plate portion (3B) and the back side supplement portion (32) of the upper side disc (3A) are separately manufactured. Not only the synthetic resin molding die, but the upper side disc (3
A special sheet metal stamping die for manufacturing the front surface side contact portion (31) of A) is also required, and the sheet metal stamping die is used to punch a through hole (3a) for a circular stainless steel plate. And the drawing in the back direction to cover the opening edge of the through hole (3a) must be performed, so that the back side replenishment section (32) is added to the front side contact section (31) of the upper side disk (3A). ), The ring-shaped plate portion (3B) needs to be integrally bonded to the back surface side replenishment portion (32) by an adhesive agent or the like, which is remarkable in the manufacturing process of the rotating body (3). It becomes complicated and the mass production effect cannot be exhibited.

In particular, in order to cover the surface side contact portion (31) in close contact with the opening edge portion of each through hole (3a) which is distributed as a plurality of openings in the upper side disc (3A), the stainless steel plate is highly accurate. It is extremely difficult to draw and form the entire surface of the front surface side contact portion (31) into a highly accurate flat surface parallel to the back surface of the ring-shaped plate portion (3B), and defective products may occur. It is easy, and if there is even a slight lack of precision, it becomes impossible to reliably and smoothly receive and convey the medal (M) to the through hole (3a).

Further, the size of the rotating body (3) itself varies depending on the model of the hopper type coin payout device, or depending on the size of the coin to be applied, the penetrating holes which are distributed in the upper side disc (3A) are opened. If the size or number of holes (3a) changes, the punching and drawing of the stainless steel plate that forms the surface side contact part (31) must be correspondingly changed, which makes the plastic working even more complicated. . The compatibility or versatility corresponding to various rotating bodies (3) cannot be exhibited.

Further, a plastic back side replenishment section (3
Since 2) and the surface side contact part (31) of the stainless steel plate are combined and integrated via an adhesive or the like, the surface side contact part (31) of the different material is disposed in the disposal of the rotating body (3).
It is difficult to separate the back side replenishment section (32) from each other, and it is not possible to reuse each of them.

[0010]

It is in continuous communication with one large arc-shaped dust discharge elongated hole (22) formed at the corresponding lower end of (1).

The upper half of the rotor receiving groove (G), which is framed in a C-shape in plan view as described above, is a circle formed integrally from the synthetic resin material of the rotor receiving disk (17) itself. As the arc-shaped edging step surface (23), it is maintained in a state of being raised by a certain constant height from the bottom surface of the groove, while the lower half portion of the rotor receiving concave groove (G) also has a shape as shown in FIG. An arcuate edging reinforcing surface metal (24) made of a metal material such as a separate stainless steel plate is attached and integrated by a fixing screw (25) from the back side thereof.

Moreover, the rotor receiving groove (G)
The edging step surface (23) and the edging reinforcing surface metal (24) are flattened so that their surfaces are continuous with each other, as suggested from FIGS. Reference numeral (26) denotes a plurality of dust discharge holes distributed in the outer peripheral surface of the edging reinforcement metal (24) and communicates with the dust discharge holes (21) opened at the groove bottom surface of the rotor receiving groove (G). is doing.

Since the rotor receiving disk (17) made of synthetic resin is in the inclined installation state, the surface of the rotor receiving groove (G) is located at the lower end arc portion of the rotor receiving groove (G) where dust is likely to accumulate. Disc rotor (R)
Or its disc rotor (R) pushes and carries the coin (C) that is conveyed to cause improper deformation, or the opening edge of the dust discharge hole (21) is locked here as an upright posture. The risk of being scraped by the coin
4) to prevent the deterioration of the durability of the synthetic resin rotor receiving plate (17).

However, as long as such a purpose can be achieved, the edging reinforcement surface metal (24) is prepared to be prepared in a large C-shape corresponding to the rotor receiving concave groove (G), and the rotor receiving concave metal (24) is prepared. You may attach and fix in the whole edging state including the upper half part of a groove (G).

Reference numeral (27) is a metallic plate-shaped coin guide piece fixed to the surface of the rotor receiving plate (17) from above as a positional relationship facing one end of the notch of the rotor receiving groove (G). 28) is a slide guide slot for a count roller formed in the rotor receiving board (17) as a positional relationship facing the other end of the notch of the rotor receiving groove (G). 17) and the base plate (11) as an elliptical shape, a count roller pivot pin (29) is inserted and erected from the back side of the base plate (11), as is clear from FIGS. There is.

Then, the mutually opposing gap between the idle count roller (30) fitted to the pivot pin (29) and the coin guide piece (27) in the fixed installation state is the disc rotor ( It is defined as the payout opening (O) of the coin (C) that is pushed forward and conveyed by R). (W) shows the opening width of the coin payout opening (O).

The pivot pin (29) for the count roller
As shown in FIGS. 8 and 10, the count lever (31), which is made of a substantially triangular metal plate piece, is vertically integrated with the middle portion of the count lever (31). 32) and is attached to the back surface of the base plate (11).

On the other hand, the other end of the count lever (31), which can rotate about its pivot screw (32), is bent in a substantially L-shape facing down, and corresponds to the base plate (11). It is adapted to be received by a stopper piece (33) which is cut and raised in a general downward direction.

Further, (34) is the coin payout opening (O).
The opening width (w) of the count roller (3) is always limited to a size smaller than the diameter (d) of the coin (C).
0) is a tension coil spring that presses and urges 0) to the state of advancing to the coin payout opening (O), and a spring receiving piece (35) cut and raised from the base plate (11) in the reverse direction.
And the counter lever (31) is connected and hung between the opposite ends of the count lever (31).

As a result, the coin (C), which is about to pass through the coin payout opening (O), has a tension coil spring (34).
The count roller (30) that receives the urging force of (3) is inevitably brought into contact with the count roller (30), and the number of paid-out sheets is reliably counted by the rotating action of the count lever (31).

Further, (36) is the base plate (1
1) A metal leaf spring attached to the back surface of the coin fastening pin (3) via a fixing screw (37), and two coin fork pins (3) arranged in parallel as a pair from the forked end of the metal leaf spring.
8) is planted integrally. Reference numeral (39) is a pair of two corresponding coin guiding pin projecting and retracting holes, both of which are the rotor receiving plate (17) and the base plate (11).
The openings are distributed in the through state.

That is, the coin guide pin (38) is always inserted into the rotor receiving groove (G) of the rotor receiving plate (17) from the back side of the base plate (11) through the coin guide pin withdrawal hole (39). It is kept in an elastically biased state in which it projects by a constant height (h) substantially corresponding to the thickness of C), and as shown in FIGS. 4 and 6, it rotates (forward) in the clockwise direction (A). Disc rotor (R)
Thus, the coin (C) that is pushed forward and conveyed is once received and guided so as to change its direction to the coin payout opening (O).

In this case, as is apparent from the enlarged view of FIG. 7, the coin receiving surface of each coin guide pin (38), which works when the disc rotor (R) rotates in the forward direction, has a flat flat groove of the rotor receiving groove (G). A vertical surface (38a) substantially perpendicular to the bottom surface of the groove is formed, and on the contrary, the back surface of each coin guide pin (38) allows the coin (C) pushed by the reverse rotation of the disc rotor (R) to escape. In addition, it is shaped as an inclined surface or an arc surface (38b) that easily sinks into the hole (39).

Disc rotor for transferring coins (R)
Is integrally molded from a synthetic resin material as shown in FIGS.

That is, in FIGS. 11 to 17 in which the disc rotor (R) is extracted and shown, (40) is the depth (s) of the rotor receiving concave groove (G) which is depressed in the rotor receiving plate (17). It is a disk rotor body shaped into a disk with a constant thickness that almost corresponds to, and has a flat surface as a whole, but its central part is to settle the coin (C) into the mutual intermediate zone with the peripheral part and to tip it over. As a conical convex element (41) of the above, the boss escape hole (20) is likewise projected from the front to a high height and also from the center.
A mounting boss (42) to be inserted into is protruding backward.

As is apparent from FIGS. 13 and 14, the conical protrusions (41) project higher than a certain thickness of the disc rotor body (40), but also the peripheral portion of the disc rotor body (40). Is a coin locking flange (4
As 3), a constant height (h) substantially corresponding to the thickness of the coin (C) is projected to the front so as to be short, and the circumferential surface of the coin (C) is received there.

Reference numeral (44) denotes a key groove cut out in the mounting boss (42) in a state of being opened backward, and fitted with a key (16) penetrating the output shaft (14) of the motor (12). It Reference numeral (45) is a ring-shaped spring receiving groove formed in the conical projection (41) in an open state, and a compression coil spring (46) is enclosed in the groove.

As is clear from FIGS. 2 and 3, the mounting bolt (47) for the disc rotor is so arranged that the compression coil spring (46) is forcedly pressed.
The disc rotor (R) can rotate integrally with the output shaft (14) of the motor (12) by being screwed and fastened from the front side into the screw hole (15) opened in the output shaft (14) of 2). It can be attached like this.

While the disk rotor (R) is rotating, there is a fear of preventing the output shaft (14) of the motor (12) from swinging illegally by the elastic repelling action of the compression coil spring (46). . Reference numeral (48) denotes a recessed surface for receiving a head, which is cut out in the conical protrusion (41) in order to sink the large-diameter head (49) of the mounting bolt (47).

A plurality of flat intermediate zones (in the example shown in the figure) are formed between the conical projections (41) forming the center of the disc rotor body (40) and the coin locking flanges (43) forming the same peripheral edge. 6 coin receiving holes (5 total)
0) is constant. C. D (Pitch Circle Diameter) (D
Apertures are distributed in an overall radial symmetry that maintains 1).
Each coin receiving hole (50) has a circular shape substantially corresponding to the size of the coin (C), and the upper edge portion of the opening is a conical saucer surface (51) and is in a state of being chamfered so that the coin (C) can be easily received. .

Further, (52) is the coin receiving hole (5
(0) has a positional relationship between adjacent ones of the disk rotor main body (40), and a plurality of them are projected backward from the disc rotor body (40) by a constant height (h) substantially corresponding to the thickness of the coin (C). In total, there are six (6) backward curved wings, and pushes coins (C) as the disc rotor (R) rotates to carry them.

That is, the flat rear surface of the disk rotor body (40), which remains as a so-called cut-out state, in opposition to the rearward protruding portion of the rear curved wing (52), and the rotor in the rotor receiving plate (17). The upper and lower mutual gaps between the receiving groove (G) and the flat bottom surface of the groove are defined so as to function as the transfer path (P) of the coin (C). The coin guide pin (3
Needless to say, 8) faces this coin transport path (P).

Each of the rear curved wings (52) has its disc rotor (R), as suggested from the enlarged view of FIG.
The rear surface of the direction of rotation (normal rotation) (A) in (1) is a concave curved surface (53r) that is curved along the opening edge of each coin receiving hole (50), and the front surface is also a convex curved surface (53).
f) Extends in a tapered form, and its convex curved surface (front surface)
The coin (C) is pushed forward and conveyed by (53f).

Moreover, the disc rotor body (4
0) A coin guiding pin (3) projecting to the coin carrying path (P) is provided at a midway portion of each backward bending blade (52) that is curved as a taper shape having a constant length from the central portion toward the peripheral portion.
8) Relief groove for coin guide pin (54) to prevent interference with
Each of the rear curved wings (52) is divided into two pieces, namely, a root side blade piece (52a) and a tip side blade piece (52b), as shown in FIG.

In this respect, the coin guide pins (38) are paired in parallel as described above to form the rotor receiving plate (1).
7) A certain height (h) into the rotor receiving groove (G)
Because of the fact that they only project, the relief groove for the coin guide pin (54) is also so-called two rows corresponding to these,
As a matter of course, the rear curved wings (52) are notched in the middle.

(55) is the disc rotor body (4
0) like the backward curved wing (52) protruding backward, the center portion and the peripheral portion of the disc rotor body (40) are also arranged as the positional relationship between the adjacent coin receiving holes (50). To the mutual intermediate band of
The reinforcing bones for a plurality of disk rotors (six in total in the illustrated example) are implanted and integrated in an overall radial symmetric distribution type, and are made of stainless steel or other metal material. Moreover,
The surface of each of the reinforcing bones (55) is exposed from the surface of the disc rotor body (40) so as to have almost the same height as the flat surface of the disc rotor body (40), as suggested from FIGS. It is kept in a retaining state.

In particular, as apparent from FIGS. 11 and 15, the reinforcing bones (55) made of the metal material come from the coin locking flange (43) forming the peripheral portion of the disc rotor body (40) to the coin (C). P. P. maintaining a constant distance (L) approximately equal to the diameter (d) of P. C. D (Pitch Circle Diameter)
It is preferable to arrange them on (D2) in the form of an overall radial symmetric distribution.

The coin rotor disc rotor (R) is a synthetic resin product as described above, and while the coin (C) is being pushed and conveyed by its rotation, the coin accommodating hopper (18).
Since the weight of the coin (C) accommodated in the standby state is added as the pushing load of the disc rotor (R), the surface of the disc rotor main body (40) is pushed by the metallic coin (C) in the standby state. Repeatedly rubbed violently and deformed irregularly, resulting in coin (C)
Will not be able to be paid out smoothly and reliably. The purpose is to prevent such a situation by the reinforcing bone (55) for the disc rotor of the metal material.

The coin (C) in the waiting state is received by the coin engaging flange (43) forming the peripheral portion of the disc rotor main body (40) by the circumferential centrifugal force of the disc rotor (R). Since the pushing-down load of the coin (C) continuing from the inside of the coin storage hopper (18) is applied to the coin (C) in the stretched state, that is, the coin (C) in the stretched state is the disc rotor body ( 40) is subjected to an undesired inclined biasing force which sinks from the circumferential surface facing the center of the disc (40), and the peripheral portion of the coin (C) causes the surface of the disc rotor main body (40), especially the diameter of the coin (C) ( d), the above-mentioned P. C. D (D
2) Above, it is easy to sink like cutting.

As a preventive measure, a plurality of disc rotor reinforcing bones (55) made of the above-mentioned metal material are provided with coin locking flanges (4) in the disc rotor body (40).
3) from P. 3 to keep a constant distance (L) approximately equal to the diameter (d) of the coin (C). C. This is because it is described that it is preferable to implant in a scattered distribution state on D (D2).

Further, the reason why the surface of each reinforcing bone (55) is made substantially the same height as the surface of the disc rotor main body (40) and is implanted in the retaining state exposed from the surface of the disc rotor main body (40) is as follows. As a result, the back side of the coin (C) is taken over, and the disc rotor main body (4
This is to keep the surface of (0) from rubbing against the coin (C).

Paradoxically speaking, each reinforcing bone (55)
When the surface of the disk rotor sinks lower than the surface of the disk rotor body (40), the disk rotor body (40)
If the surface of each reinforcing bone (55) protrudes higher than the surface of the disc rotor main body (40), the surface of each reinforcing bone (55) may still be rubbed by the coin (C) and may be deformed like a depression. The coin (C) hits against this and cannot be smoothly and reliably received in the coin receiving hole (50) of the disc rotor body (40).

In this respect, in the basic embodiment shown in FIGS. 11 to 17, each of the disc rotor reinforcing bones (55) is composed of a large-diameter head portion (56) and a small-diameter leg shaft portion (57). The disc rotor main body (40) is embodied as a pin (55a) having a stepped form, and has a stepped form implantation hole (58) corresponding to the pin (55a) of the stainless steel rod.
Above all in P. C. The reinforcing bones (55) are bored in a scattered distribution state on the D (D2), and from the front side of the disc rotor body (40) to the inside of each of the implantation holes (58).
The pin (55a) that becomes is integrated by press fitting.

If such a structure is adopted, the step portion of the pin (55a) which becomes the reinforcing bone (55) for the disc rotor and the implantation hole (58) serves as a positioning stopper, and the pin (55a) is set to the above diameter. The self-propelled and easy-to-insert holes (5) are provided so that the surface of the large head (56) is substantially level with the surface of the disc rotor body (40).
It can be press-fitted into 8), which is convenient for planting work.

However, the pin (55a) may be a simple straight metal round bar or square bar, and in any case, the surface exposed to the surface of the disc rotor body (40) is as shown in FIG. It is preferable to form such a convex curved surface (59).

In this way, even if the surface of the pin (55a) is implanted in a state in which it projects slightly higher than the surface of the disc rotor body (40), the coin (C) does not hit it, and This is because by sliding on the convex curved surface (59), it can be received in the coin receiving hole (50) of the disc rotor body (40) without any trouble. At the same time, the work of implanting the disc rotor body (40) can be easily performed without any restriction.

18 and 19 show a first modified embodiment of the reinforcing bone (55) for a disc rotor, and as will be apparent from this, the middle height of the pin (55a) press-fitted into the implant hole (58). The collar position (60) with a slightly larger diameter.
As a result, the outer peripheral surface of the collar portion (60) may be roughened by knurling or protruding to keep the stopper hole (58) in a retaining state.

As suggested together with FIGS. 18 and 19, instead of modeling the surface of the head (56) as a convex curved surface (59), the corner positions of the head (56) are chamfered. Alternatively, a roll pin having a C-shaped cross section may be used as the pin (55a).

Further, as shown in the second modified embodiment of FIGS. 20 and 21, the flange portion (60) protruding from the mid-height position of the pin (55a) is easily press-fitted into the implantation hole (58) and is hard to be removed. It is also conceivable to form it into a wedge shape that is thinner.

22 and 23 also relate to a third modified embodiment of the reinforcing bone (55) for a disc rotor, in which a steel ball (55b) is adopted as the reinforcing bone (55) and this is also used in the disc rotor main body (40). ) May be press-fitted and integrated from the front side into the recessed groove (61) formed in (). Steel ball (55
It goes without saying that the convex curved surface (surface) (59) of b) is exposed from the surface of the disc rotor body (40).

24 and 25 show a fourth part of the reinforcing bone (55).
9 shows a modified embodiment, and as is apparent from this, a cylindrical roller or a cylindrical needle (55
c) is adopted, and this is the disk rotor body (40)
It is also possible to press-fit and integrate into the mutual recessed zone between the central part and the peripheral part in the inside of the recessed groove (61) formed as a corresponding constant length (Z), also from the front side in a horizontally installed state. is there.

The steel ball (55b) of the third modified embodiment and the rollers and needles (5) of the fourth modified embodiment.
5c) is adopted, the disc rotor body (4
As long as it is kept in the state of being prevented from slipping off to 0), its surface may rub against the coin (C) and freely roll in the implantation groove (61).

Further, FIGS. 26 to 31 also show the reinforcing bone (5
5) 5th to 7th modified embodiments of the present invention are shown, and as is clear from various types thereof, a leaf spring (55) bent from a metal material such as a stainless steel plate into an inverted U-shaped section or an inverted V-shaped section.
As d), a corresponding constant length (Z) formed in the disc rotor body (40) as in the fourth modified embodiment.
It may be integrated by press-fitting into the implantation groove (61) from the front side in the horizontal installation state.

In this case, a pair of wedge pieces (62), which are easily pressed into the lower end portion or the middle portion of the leaf spring (55d) and which are hard to come off, are formed by overhanging by press working such as bending and raising. It is desirable to fix and maintain the state where it is prevented from coming off from the recessed groove (61).

Since the other constructions of the first to seventh modified embodiments are substantially the same as those of the basic embodiment,
18 to 31 are allotted with the reference numerals corresponding to those in FIGS. 11 to 17, and detailed description thereof is omitted.

Reference numerals (63) in FIGS. 4, 6, 11 to 17 indicate reinforcing pins of the aforesaid backward curved wing (52), and a plurality of them (six in total in the illustrated example) are the tip side blades (52b).
Are integrated into the front end corners in a scattered distribution state. (D3) is the overall P.I. in which the reinforcing pins (63) for the backward curved wing are distributed. C. D (Pitch Circle Diameter)

It is possible to prevent wear of the product, chipping or cracking from the corners of the front end thereof.

On the other hand, the surface of each reinforcing pin (63) has substantially the same height as the surface of the disc rotor main body (40), like the surface of the above-mentioned disc rotor reinforcing bone (55). Is exposed from the front surface of the coin (C) so that the back surface of the coin (C) can be supported. The rearward bending blade reinforcing pin (63) is also made of a metal material such as a stainless steel rod and is also used to reinforce the disc rotor (R) itself.

In the illustrated embodiment, the reinforcing pin (63) for the rear curved wing has the reinforcing bone (5) for the disc rotor.
As with the pin (55a) that becomes 5), the head with a large diameter (6
4) and a leg shaft portion (65) having a small diameter, as a stepped columnar type, into a corresponding stepped-shaped stud hole (66) formed in the disc rotor body (40), also from the front side. It is integrated by press fitting. Moreover, the surface of the head portion (64) having a large diameter is preferably shaped as a convex curved surface (67). The effect of such a structure is obtained by using the pin (55) adopted as the reinforcing bone (55) for the disc rotor.
It is similar to that of a).

In the hopper type coin payout device of the present invention configured as described above, the coin rotor disk rotor (R) is driven by the drive motor (12) thereof, and the clocks shown in FIGS. 4, 6, 7, 11, and 15 are obtained. When rotated (normally rotated) in the direction (A), a large number of coins (C) stored in the coin storage hopper (18) are individually inserted one by one into the coin receiving holes of the disc rotor main body (40). Through the (50), it is taken into the coin carrying path (P) defined between the rotor receiving disc (17) and the rotor receiving groove (G), and is faced down from the disc rotor body (40). Curving wing (52)
As a result, the coin is guided in the coin transport path (P) toward the coin guide pin (38).

The coin guide pin (38) faces the inside of the coin carrying path (P), and the rotor receiving plate (17) is also provided.
The coin (C) pushed forward and conveyed as described above eventually comes to the coin guide pin (38) because it is located near the coin payout opening (O) cut out in the rotor receiving groove (G). ), It is guided to change the direction from the transfer path (P) to the coin payout opening (O), and together with the rotational centrifugal force of the disc rotor (R) acting on the coin (C). , Resulting in being paid out from the coin payout opening (O).

For the coin (C) which is received in the coin receiving hole (50) of the disc rotor body (40) and is being pushed forward by its rotation, the coin (C) is waiting in the coin accommodating hopper (18). The pushing-down load of the coin (C) accommodated as the above is applied, but the load is distributed on the surface of the reinforcing bone (55) for the disc rotor, which is scattered between the adjacent coin receiving holes (50), and further. The coin (C) is supported by the surface of the rear curved wing reinforcing pin (63), and the surface of the disc rotor body (40) is rubbed with the coin (C) to cause cutting. There is no danger of being deformed into an irregular asperity as if it were done.

Further, the coin (C) which has received the centrifugal force of rotation in the above-mentioned push-forward transfer process is projected from the coin receiving hole (50) of the disc rotor body (40) to the convex curved surface (front surface) of the rear curved wing (52). Along the (53f), it comes in contact with the rearward bending blade reinforcing pin (63) and is gradually sent out to the coin payout opening (O), and is returned into the coin receiving hole (50) as if it were accidentally caught. There is no fear of doing it. This means that the rotor receiving plate (17) is in an inclined installation state at a constant angle (α), and the coin payout opening (O) is cut out at an obliquely upper position of the rotor receiving groove (G). It can be said that being active also works effectively.

Then, the circumferential surface of the coin (C) passing through the coin payout opening (O) restricts the opening width (w) of the coin payout opening (O) to a narrow count roller ( 30) is inevitably contacted and the count lever (31) is caused to rotate, whereby the number of coins (C) to be paid out is accurately counted.

If a bite of the coin (C) occurs during pushing and transporting the coin (C) by the disc rotor (R), the disc rotor (R) may be turned over by a sensor (not shown). Since the coin (C) gets over the coin guiding pin (38) by being reversed in the clockwise direction, the disc rotor (R) is normally rotated again after the biting phenomenon is released, so that the coin (C) is paid out. The action can be continued without any trouble.

As described above, according to the present invention, the disk rotor body (40) formed of a synthetic resin material in the shape of a disk having a flat surface has a conical projection (41) and a back surface at the center of the disk rotor body (40). Rotation drive motor (1
2) A mounting boss (42), a coin locking flange (43) protruding in the same manner at the peripheral portion, and a coin locking flange (43) protruding toward the front side, and a radially symmetrical type opening in the intermediate region between the central portion and the peripheral portion. A plurality of circular coin receiving holes (50) distributed respectively are provided, and

Similarly, between the adjacent coin receiving holes (50) of the disc rotor body (40), the rear surface in the direction of rotation (A) is a concave curved surface along the opening edge of each coin receiving hole (50). In the disc rotor (R) for coin transfer of the hopper type coin payout device in which a plurality of backward curved blades (52) which are (53r) and whose front surface is a convex curved surface (53f) are projected backward,

A plurality of reinforcing bones (55) for a disc rotor, which are made of metal or other metal, and are scattered in a radial symmetrical pattern between the adjacent coin receiving holes (50), are provided. Since the surface of the disk rotor body (40) has a blunt surface, the disk rotor body (40) is exposed to the same height as the surface of the disk rotor body (40), so that the problems of the prior art described at the beginning can be alleviated.

That is, according to the above-mentioned constitution of the present invention, the reinforcement for the disc rotor made of a separate metal material is provided between the coin receiving holes (50) distributed in the synthetic resin disc rotor body (40) adjacent to each other. Since a plurality of bones (55) are implanted in a retaining state as an overall radial symmetrical distribution type, the size of the disc rotor for coin transport (R) itself changes, or the coin ( Even if the size and the number of the coin receiving holes (50) change depending on the size of C), the same reinforcing bone for disc rotor (55) is implanted without being affected by this. Since the reinforcing effect of the disc rotor (R) can be achieved, the versatility or compatibility is remarkably excellent.

Moreover, since a plurality of the above-mentioned disc rotor reinforcing bones (55) are implanted in such a state that they are exposed at substantially the same height as the flat surface of the disc rotor main body (40) whose surface is clogged, the implantation work In addition to allowing anyone to easily and correctly, the surface of the reinforcing bone (55) exposed on the surface of the disc rotor body (40) allows the coin (C) to slide, while ensuring the back surface As a result, the disc rotor body (4
There is no possibility that the surface of 0) will be strongly rubbed by the metal coin (C) and be deformed into an irregular asperity.

According to the second aspect of the invention, the back surface of the rear curved wing reinforcing pin (63) comes into contact with the coin (C) to prevent the rear curved wing (52) from being worn or damaged. In addition, the surface of the reinforcing pin (63) also functions to reinforce the disc rotor (R) itself, and in combination with the disc rotor reinforcing bone (55), the disc rotor (R) becomes more rational. There is an effect that can reinforce.

Particularly, if the configuration of claim 3 is adopted,
The coin locking flange (43) forming the peripheral portion of the disc rotor body (40) maintains a constant distance (L) which is substantially equal to the diameter (d) of the coin (C). C. D (D
2) The surface of the disc rotor main body (40) that is most likely to be illegally deformed by the coin (C) above,
The reinforcing bone (55) for the disc rotor at the corresponding position can surely prevent it.

When the constructions according to claims 4 to 6 are adopted, commercially available pins (55a) and steel balls (55) are used.
b), since the roller or the needle (55c) can be used, a special mold for manufacturing the reinforcing bone (55) for the disc rotor is not required, and anyone can easily press-fit and integrate it properly. There is no risk of defective products, and the mass production effect is also outstanding.

Furthermore, the reinforcing bone (55) for a disc rotor, which comprises a roller or a needle (55c) and a leaf spring (55d) as claimed in claims 6 and 7, is attached to the disc rotor main body (4).
0), the surface of the disc rotor main body (40) is coin (C) if it is press-fitted into the recessed groove (61) formed corresponding to 0) in a horizontally installed state extending by a certain length (Z). There is an effect that it is possible to prevent the possibility of unauthorized deformation due to rubbing against

In any case, since the disc rotor reinforcing bone (55) is made of a metal material and is embedded in the synthetic resin disc rotor body (40), the disc rotor (R) is discarded. It can be said that both of them can be easily sorted and reused for each of them.
