A return spring (43) for continuously lowering and biasing the traction is continuously stretched.

Then, the separate cam roller (3)
7) is rotatably pivoted around an eccentric support shaft (36) protruding forward from a halfway portion deviated to the tip side of the swing arm (39), and its cam roller (37). Is exposed to the interior of the room plate (12) through the separate cam roller advance / retreat guide slot (24) opening in the base plate (11) of the rotor receiving plate (M), and can come into contact with the coin (C). I have.

The swing arm (39) is in a state of receiving the downward urging force of the return spring (43), and a separate cam roller (37) is axially supported in the middle of the swing arm (39). ) Always faces the lower end (start point) of the advance / retreat guide slot (24), and keeps the coin outlet (O) at a regular constant opening width (W2).

However, a guide column (45) intersecting with the swing arm (39) is attached and fixed to the base plate (11) of the rotor receiving plate (M) from behind by a plurality of bolts (44). And a swing regulating groove (4) cut out at an intermediate height position of the guide support (45).

Reference numeral (48) denotes a spring receiving pin which is planted and fixed in a forwardly protruding state in a halfway portion of the swing arm (39) which is deviated toward the base end, and a spring attached to the cam roller (37). A return spring (38) for urging the cam roller (37) to rotate around the eccentric support shaft (36) in a returning direction is continuously stretched between the left and right sides of the hanging piece (47). I have.

That is, the separate cam roller (3)
Regarding the positional relationship between 7) and the eccentric support shaft (36), as shown in FIG. 15, the circular center (P1) of the coin (C) is located at the radius of curvature of the radially curved blade (35) of the disk rotor (R). (P2) and cam roller (3
7) A thought line (DD) connecting the center of the circle (P3).
If it is assumed that the coin (C) is accidentally positioned on the upper side and is bitten into a so-called tension state between the disk rotor (R) pushing the coin and the cam roller (37) receiving the coin, the so-called tension is applied. Roller (3
7) The eccentric support shaft (36) occupies an eccentric position separated by a certain amount (X) in either the left or right direction from the thought line (DD), and the return rotation biasing return spring (38). )) And the biting coin (C)
The return spring (3
The return rotation urging force in 8) is always applied to the cam roller (37), and the cam roller (37) is kept in a constant directional positioning state with respect to the eccentric support shaft (36). (P4) indicates the center of the eccentric support shaft (36).

As a result, the cam roller (37) receives a pressing force stronger than the return rotation urging force of the return spring (38) from the biting coin (C) and moves to the coin outlet (O). When retreating along the advance / retreat guide long hole (24) from the approached initial position, in the process, it freely idles around the eccentric support shaft (36) and reduces the pressing force from the coin (C). Either, the biting coin (C) is instantly re-sent to the inside of the disc rotor (R) again or sent out from the coin sending-out port (O) to the coin sending path (16), and the coin (C) The prevention of biting is achieved.

In this case, in the embodiment shown in FIGS. 1 to 15, the separate cam roller (37) is pivotally supported in the middle of the swing arm (39) which can swing vertically.
As is suggested from the first modified embodiment of FIG. 16 corresponding to FIG. 16, the base plate (1) of the rotor receiver (M) is
The back cover plate (49) of the separate cam roller advance / retreat guide slot (24) is attached and fixed from the rear to 1), and the cam roller (36) projecting forward and integrally from the cam roller (49). 37) is freely rotatably pivoted within the advance / retreat guide slot (24), and a spring hook (47) projecting laterally and integrally from the cam roller (37), and the back cover plate (49). ) From the cam roller (3) to the left and right sides with the corresponding spring-loaded pins (48) protruding forward.
The return rotation urging return spring (38) of 7) may be connected and stretched.

The installation of the swing arm (39) is omitted, and the cam roller (37) is fixed to the rotor receiving plate (M) or the back cover plate (4) attached thereto.
It is also a purpose that can be pivoted to 9). In addition, as long as the cam roller (37) is able to rotate around the eccentric support shaft (36), the shape of the cam roller (37) is circular as shown in FIG. Not only that, it can be shaped into an oval or a rounded triangle.

FIG. 17 shows a coin (C) using the present invention.
3 shows a normal delivery operation state of. In the hopper type coin delivery device having the above-described configuration, when the coin delivery disk rotor (R) is rotationally driven in the direction of the arrow (A) by the drive motor (8), the coin storage hopper (H).
The coins (C) stored in the at-random posture state are received one by one into the coin receiving holes (34) of the disc rotor (R), and the disc rotor (R) itself is received. The radially curved blade (35) subjected to the rotational centrifugal force pushes the inside of the circular rotor receiving recess (G) of the rotor receiving board (M), and then sequentially and neatly sends out coins through the coin outlet (O). It is forcibly picked up and sent out to the road (16).

At this time, the separate cam roller (37) of the separator (S) is moved by the swing arm (39) which receives the urging force of the return spring (43) to lower the base plate (M) of the rotor receiver (M). 11) Opening / closing guide slot for separate cam roller (2)
4), approaching the coin outlet (O) at the lower end (start point) of the coin outlet (O), and opening the coin outlet (O) with a regular opening width (W2) substantially equal to the diameter of the coin (C). )
I keep it.

Then, in the unlikely event that the coin (C) has a circular center (P
1) is accidentally positioned on a thought line (DD) connecting the center (P2) of the radius of curvature of the radially curved blade (35) and the circular center (P3) of the separate cam roller (37). When the coin (C) is bitten in a so-called thrust state between the radially curved blades (35) of the disc rotor (R) and the cam roller (37), from the initial moment until the coin is released. Figure 1 shows the process
As shown in FIGS. 8 and 19, in the present invention, the swing arm (39) of the separate cam roller (37) that has received the biting coin (C) is forcibly opposed to the pull-down urging force of the return spring (43). Until the cam roller (37) retreats from the lower end (start point) to the upper end (end point) of the advance / retreat guide slot (24), and receives the pressing force of the biting coin (C). The eccentric support shaft (3
At around the point 6), the coin (C) slides in the direction of the arrow (B) in FIG. 19, and the tension state of the biting coin (C) is instantaneously eliminated. ) Can be sent inside. As a result, biting of the coin (C) is effectively prevented, and there is no possibility that the drive motor (8) of the disc rotor (R) stops its rotation.

As soon as the tension state of the biting coin (C) is released, the separate cam roller (37) receiving the return rotation urging force of the return spring (38).
Self-swiftly returns to its original constant directional positioning state by itself around the eccentric support shaft (36), and the swing arm (39) on which it is supported is also returned by its return spring ( The cam roller (37) is pulled down by the biasing force of (43) by itself, so that the cam roller (37) has its advance / retreat guide slot to keep the coin outlet (O) at the original regular opening width (W2) as shown in FIG. It will be located at the lower end (start point) of (24), and will be used for the subsequent coin (C) sending operation.

In the hopper type coin delivery device shown in FIGS. 1 to 19, the rotor receiving plate (M) has a circular rotor receiving recess (G) through a coin delivery port (O).
The coin (C) is forcibly picked up and delivered to the upper coin delivery path (16), and the biting coin (C) is used to separate the coin (C) from the separate cam roller (37) of the separator (S). ) To re-enter the inside of the disc rotor (R), but as suggested in the second modified embodiment of FIGS.
Similarly, in order to pay out coins (C) in the horizontal direction from the rotor receiving recesses (G) of the rotor receiving board (M) through the coin feeding and exiting port (O), for example, the coin delivery path used in a slot machine. The present invention can be applied and implemented without any problem even in a hopper-type coin payout device without (16).

At this time, as can be confirmed by comparing FIGS. 1 and 5 with FIGS.
The eccentric support shaft (36) of (7) is disposed at a position away from the above-mentioned thought line (DD) in the lateral direction opposite to that of FIG. 15, and the emergency biting coin (C) is disc-rotored again. (R)
May be configured to be sent out from the coin outlet (O) without being sent into the inside.

The coin (C) pushed forward by the disc rotor (R) is once received, and the coin receiving port (O) is received from the rotor receiving recess (G) of the rotor receiving board (M). It is a coin guiding pin to go to. Since other configurations and operations are substantially the same as those of the embodiment of FIGS. 1 to 19, FIGS.
Only the reference numerals corresponding to .about.19 are entered, and the detailed description of the second modified embodiment is omitted.

Each of the coins (C) received from the hopper (H) into the coin receiving hole (34) of the disk rotor (R) is pushed forward by the radially curved blade (35) of the disk rotor (R). In a hopper type coin delivery device for sequentially forcibly sending out from the rotor receiving recess (G) of the rotor receiving board (M) to the coin delivery port (O),

A separate cam roller (37), which always faces the coin outlet (O) so as to keep the opening width (W2) substantially equal to the diameter of the coin (C), is spring-loaded to project integrally from itself. The return spring (38) for urging the return rotation, which is connected and stretched between the piece (47) and the rotor receiving board (M),

The circular center (P1) of the coin (C) is defined by the center (P2) of the radius of curvature of the radially curved blade (35) of the disk rotor (R) and the circular center (P3) of the cam roller (37) itself. The radially curved blade (35) pressed by the coin (C), which is accidentally positioned on the thought line (DD) to be connected, and the cam roller (3) for receiving the coin.
7) If it is assumed that it is bitten in a state of tension between the opposing faces,

The eccentric position occupies an eccentric position separated by a fixed amount (X) in either the left or right direction from the thought line (DD), and the extension line (LL) of the tension action of the return spring (38).
