A spring receiving piece (30) cut and raised rearward from the base plate (11) and a vicinity of a tip end of the count lever (26) are connected to each other and are connected and suspended.

As a result, the coin (C) which is going to pass through the coin payout opening (O) is moved by the tension coil spring (2).
The count roller (25) that has received the urging force of (9) is inevitably contacted, and the number of payouts is reliably counted by the rotating action of the count lever (26).

Further, at (31), the disc rotor (R) rotating (forward) in the clockwise direction (A) once receives the pushed and conveyed coin (C), and goes to the coin payout slot (O). It is a coin inductor for guiding to change the direction, and is attached to and integrated with a back surface of the base plate (11) via a fixing screw (32).

It is shaped as.

However, the coin inductor (31) and the hole (33) may be reduced one by one or increased by three or more. Further, according to the configuration of the illustrated embodiment, there is an advantage that the coin inductor (31) can be easily formed from a single metal leaf spring material. However, the coin inductor (31) is provided with a pin separate from the metal leaf spring material. Alternatively, it may be possible to attach the pin to the leaf spring material in a standing state, or to urge the pin to project to the rotor receiving groove (G) by a separate compression coil spring.

The above-mentioned coin transport disc rotor (R)
Is molded from a synthetic resin material as shown in FIGS. That is, in FIGS. 11 to 16 in which the disk rotor (R) is extracted and shown, (34) denotes a disk-shaped disk having a constant thickness corresponding to the rotor receiving groove (G) of the rotor receiving disk (16). The rotor itself,
The central portion of the coin (C) stands upright as a conical convex (35) for calming and falling down to the peripheral portion, and is also inserted from the central portion into the boss escape hole (19). Mounting boss (36) protrudes rearward.

Reference numeral (37) denotes a key groove cut out in the mounting boss (36), and the key groove is engaged with a key (15) passing through the output shaft (14) of the motor (12). The motor (12) and the disk rotor body (34) can rotate integrally. (3
8) indicates a reinforcing rib provided on the back surface of the disk rotor body (34) so as to be interposed between the central portion and the peripheral portion.

A plurality of circular coin receiving holes (39) are formed in the periphery of the disk rotor body (34). C. The aperture is formed in an overall radially symmetric distribution type maintaining D (Pitch Circle Diameter) (d1). Each coin receiving hole (39) corresponds to the size of the coin (C), and its opening edge is a conical receiving surface and is chamfered so as to easily receive the coin (C).

(40) The coin receiving hole (39)
As a positional relationship interposed between adjacent ones, a plurality of back-curvature wings protruding from the disk rotor body (34) integrally with each other so as to protrude from the disc rotor body (34) by a certain height (h) substantially corresponding to the thickness of the coin (C). The coin (C) is pushed and conveyed with the rotation of the disc rotor (R).

That is, as opposed to the rearwardly protruding portion of the rearwardly curved wing (40), the back surface left as a notch in the periphery of the disk rotor main body (34) and the rotor backing disk (16). The upper and lower mutual gaps facing the groove bottom of the rotor receiving groove (G) are defined so as to function as the coin transport path (P). The coin inductor (31) faces this coin transport path (P).

As indicated by the dashed line in FIG. 15, the rear surface of each of the above-mentioned curved back wings (40) has a rear surface in the rotation (forward) traveling direction (A) of the disc rotor (R) in the coin receiving hole (39). ) Concave surface along the opening edge (41r)
And the front surface also extends in a tapered shape having a convex curved surface (41f), and the coin (C) is pushed forward by the convex curved surface (front surface) (41f).

Moreover, the disk rotor body (3
A coin inductor (31) protruding into the above-mentioned rotor receiving groove (G) is provided in the middle of each of the back curved wings (40) curved as a taper of a fixed length from the center to the periphery of 4). Escape slot for coin inductor (4

In this respect, in the illustrated embodiment, since the coin inductor (31) is projected into the rotor receiving groove (G) as a pair of two in parallel as described above, the coin inductor The relief grooves (42) are notched in the so-called two rows corresponding to these, in the middle of the curve of each backward curved wing (40), but may be cut off as one row or three or more rows.

Reference numerals (43a) and (43b) denote convex corners (front surfaces) (41f) of the respective rearwardly curved wings (40). 40b) are metal reinforcing pins that are implanted and integrated in a dotted distribution at two places with the front corner of the front end, and are the same as the rearward curved wing (40) facing backward from the disk rotor body (34). It protrudes by the height (h).

Then, as the reinforcing pins (43a) and (43b) rotate (forward) in the clockwise direction (A) in the disk rotor (R), the rotating centrifugal force causes the reinforcing pins (43a) and (43b) to move out of the coin receiving hole (39). The coin comes into contact with the coin (C) to be delivered to the coin payout opening (O), and the root side wing piece (40a) and the tip side wing piece (40b) of each of the above-mentioned backward curved wings (40) are worn or their front end angles. Prevent chipping or cracking from corners.

In this case, the reinforcing pins (43a) (43)
The reinforcing pins (43a) are in close contact with the respective front end corners so that b) forms the front end corners of the root side wing piece (40a) and the front end corners of the tip side wing piece (40b). (4
3b) may be implanted and integrated, but as is evident from the illustrated embodiment, the root wings (40
By cutting out both the front end corner of (a) and the front end corner of the tip side wing piece (40b) as a concave curved surface (44), the circle of the concave curved surface (44) and the reinforcing pins (43a) (43b) is cut. It is preferable to secure a certain gap (s) between the facing surfaces.

Then, the reinforcing pins (43a) (43)
The receiving force of the coin (C) due to b) does not directly propagate to the front end corner of the root-side wing piece (40a) or the front end corner of the tip-side wing piece (40b). Chipping and cracking can be more effectively prevented, and the durability of the disc rotor (R) can be increased.

A reinforcing pin (43a) that is implanted and integrated into the corner at the front end of the root-side wing piece (40a) is shown in FIG.
Evident from its overall P.C. C. D (Pitch Ci
rcleDiameter) (d2) is inserted into the coin receiving hole (39) of the disc rotor body (34). C. It is desirable to set the diameter smaller by a certain amount (L) than D (d1).

In this case, since the reinforcing pin (43a) comes into contact with the eccentric position of the coin (C) as soon as possible, it is possible to give the coin (C) an assisting force for sending out from the coin receiving hole (39). Yes, disk rotor (R)
In combination with the rotational centrifugal force, the coin (C) can be more reliably and stably sent out.

The reinforcement pin (43a) implanted in the corner of the front end of the root side wing piece (40a) has a P.I. C. D (d2)
Is the overall P.I. of the reinforcing pin (43b) implanted in the front corner of the tip wing piece (40b). C. D (d3)
Needless to say, the diameter is smaller than that.

Further, the root-side wing piece (40) which forms the convex curved surface (front surface) (41f) of each backward curved wing (40).
It is preferable that a guide step (D) for assisting coin feeding is provided between the front surface of a) and the front surface of the tip-side wing piece (40b).

In other words, as suggested by the chain line in FIG. 15, the radius of curvature (r1) for curving the front surface of the root-side wing piece (40a) as a convex curved surface (41f) is large, and the front surface of the tip-side wing piece (40b) is enlarged. The curvature radius (r2) for shaping as a convex curved surface (41f) is changed slightly differently, and the convex curved surface (front surface) (41f) of the tip side wing piece (40b) is rotated (forward rotation) in the disk rotor (R). Due to the relationship with the traveling direction (A), the reinforcement is disposed behind the convex curved surface (front surface) (41f) of the root-side wing piece (40a) and is implanted in the front corner of the tip-side wing piece (40b). Pin (4
The circumferential surface of 3b) is kept in a state of being inscribed from the rear side with an imaginary line having a large radius of curvature (r1) in the root-side wing piece (40a).

At this time, it is preferable that the center of the reinforcing pin (43a) to be implanted in the corner at the front end of the root-side wing piece (40a) is arranged on an imaginary line having a large radius of curvature (r1).

Then, the disk rotor body (3
The coin (C) in the process of being sent out by receiving the rotational centrifugal force from the coin receiving hole (39) of (4) is located at the front end corner of the root-side wing piece (40a) as suggested by the chain line in FIG. The reinforcing pin (43b) which comes into contact with the reinforcing pin (43a) to be formed quickly and continues from the convex curved surface (front surface) (41f) of the root side wing piece (40a) to the front end corner of the tip side wing piece (40b). Contact with the tip side wing piece (40
As the coin (C) is fed through the convex curved surface (front) (41f) of (b), a so-called stepwise assisting force is applied to the coin (C) in the feeding direction, so that the coin is more reliably and stably sent out. Therefore, there is no possibility of accidental return to the coin receiving hole (39) of the disk rotor body (34).

In any case, each of the reinforcing pins (43a)
As (43b), a stepped cylindrical type as shown in FIG. 16 is adopted, and a pin implantation hole (45) in a stepped form corresponding to this is formed in the disk rotor body (34), By pressing the small-diameter legs (46) of the reinforcing pins (43a) and (43b) into the pin implantation holes (45) from the back side of the disk rotor body (34), the reinforcing pins (43a) and (43b) are also pressed. It is desirable that the large-diameter head (47) protrudes from the back surface of the disk rotor body (34) by the same constant height (h) as the above-mentioned curved back wing (40). Cover each reinforcing pin (43a) (43
This is because the reinforcing pins (43a) and (43b) can be easily and correctly implanted by using the step (b) and the step portion of the implant hole (45) as a positioning stopper.

In the embodiment illustrated in FIGS. 11 to 16, the front corners of the root wings (40a) forming the respective rearwardly curved wings (40) and the front corners of the tip wings (40b) are also formed. The reinforcing pins (43a) and (43b) are implanted and integrated at two locations. However, as shown in the modified embodiment of FIGS. 17 and 18, the reinforcing pins (43b) are provided only at the front corners of the tip wing piece (40b). ) May be implanted, and although not shown, a reinforcing pin (43a) may be implanted only in the corner at the front end of the root side wing piece (40a).

Further, as apparent from the modified embodiment of FIG. 19, when each reinforcing pin (43a) (43b) is implanted, its leg (46) is connected to the disk rotor body (3).
By intentionally projecting a predetermined height (h1) from the surface of 4), the protruding leg (46) can also function as a coin stirring pin.

Then, the reinforcing pins (43a) (4)
3b), the protruding legs (46) are interspersed and distributed between adjacent ones of the coin receiving holes (39) in the disk rotor body (34). Can be efficiently stirred.

Since the other configurations in the modified embodiment of FIGS. 17 to 19 are substantially the same as those of the above embodiment of FIGS. 11 to 16, the corresponding reference numerals to FIGS. , And a detailed description thereof will be omitted.

In the hopper type coin payout apparatus having the above-described structure, when the disk rotor (R) is rotated (forward) in the clockwise direction (A) in FIGS. The coins (C) accommodated in the hopper (17) pass through the coin receiving holes (39) of the disk rotor body (34) one by one, and the coin transport path (P) defined on the back side thereof. The coin is conveyed to the coin transport path (P) by a backward curved wing (40) protruding backward from the disk rotor body (34).
Is pushed toward the coin inductor (31).

The coin inductor (31) faces the inside of the coin transport path (P), but is located in the vicinity of the coin payout opening (O) cut out in the rotor receiving groove (G). Therefore, the pushed coin (C) is once received by the coin inductor (31), and is guided to change its direction from the coin transport path (P) to the coin payout slot (O). Coupling with the rotational centrifugal force of the disc rotor (R) acting on the coin (C) results in the coin being paid out from the coin payout opening (O).

The coin (C) which has been subjected to the rotational centrifugal force in the process flows from the coin receiving hole (39) of the disk rotor body (34) along the convex curved surface (front surface) (41f) of the backward curved wing (40). And the reinforcing pins (43a) (4
3b), the paper is gradually fed out to the coin payout opening (O), and there is no possibility that the coin is returned to the coin receiving hole (39) so as to be accidentally involved. This is also effective when the rotor receiving plate (16) is in an inclined installation state, and the coin payout opening (O) is cut off at an obliquely upper position of the rotor receiving groove (G). It can be said that it works.

The coin (C) passing through the coin payout slot (O) necessarily comes into contact with the count roller (25) which urges the opening width (W) to be narrow.
Since the count lever (26) is rotated, the number of coins (C) paid out is accurately counted.

If a coin (C) bites during the pushing and transporting of the coin (C) by the disc rotor (R), the disc rotor (R) is detected by a sensor (not shown). The coin (C) gets over the coin inductor (31) by being reversely driven in the counterclockwise direction. After the bite phenomenon is released, the disc (R) is rotated forward again to thereby rotate the coin (C). Can be continued without any trouble.
