However, in the above-described prior art, the structure has an extruding member for extruding the coin toward the outlet portion, and a guide means for guiding the extruding member, and is extruded by the extruding member. Coins are discharged to the outlet by a restriction pin. For this reason, the number of parts is large, and the mutual adjustment of the guide means and the push-out member formed on the rotating plate and the substrate is delicate and may cause a cause of failure. Moreover, since the pushing member and the guide means are relatively movable, their movement is hindered by coins, miscellaneous matters, and the like, and there is a possibility that the sending of coins may stop.

The present invention has been made to solve the above-described problems in the prior art, in order to guide coins (coins) to the discharge port on the back surface (base plate side) of the rotating disk (rotating plate) and push it out from the discharge port. It is an object of the present invention to provide a coin sending device that can discharge coins (coins) with an extremely simple structure by integrally forming the coin pressing wall.

The base member 1 has a side pentagonal box shape, and forms a rectangular inclined mounting portion 11 protruding forward on one surface. The inclined mounting portion 11 is formed with a rectangular fitting hole 12 into which the base plate 2 is fitted.

The base plate 2 is formed in a rectangular shape as a whole, and a circular recess 21 is formed on the upper surface (coin hopper 4 side). At the center of the circular recess 21, a through hole 22 through which the output shaft 52 of the drive device 5 passes and two annular grooves 23 are formed in the substantially radial center portion. The rotary disk 3 is rotatably fitted in the circular recess 21 described above, and a pair of convex parts 34 formed on the lower surface 32 of the rotary disk 3 is fitted in the annular groove 21. Further, hooks 24 that are engaged with the edges of the fitting holes 12 formed in the base member 1 are provided on the upper and lower sides of the rectangular main body portion. The upper and lower edges are formed with holes 28a and 28b for fitting the engagement hooks 44 provided on the coin hopper 4. A crank-shaped locking lever 29 that crosses the hole 28 is provided in the hole 28a at the upper edge. The locking lever 29 is urged downward of the base plate 2 by a spring 291.

Further, as shown in FIG. 2, the base plate 2 is provided with a coin discharge port 25 communicating with the upper left circular recess 21 through an opening 251. In the vicinity of the opening 251 of the coin discharge opening 25, a fixed shaft 26 and a movable shaft 27 are disposed apart from each other. Coin C (in the present invention, a generic name including medals, coins, etc.) is released through the two axes. The movable shaft 27 is fixed to a movable bracket 271 provided with a movable sensor S1 at the tip, and the movable bracket 271 swings by the movement of the movable shaft 27, and the movable sensor S1 provided at the tip is fixed to the fixed sensor. By passing between S2, the number of coins C released is counted. The movable bracket 271 is always locked by a spring 272 so as to urge the movable shaft 27 toward the fixed shaft 26. In addition, a stopper 273 of the movable bracket 271 protrudes at a position facing the fixed shaft 26. A buffer member 274 for buffering the collision of the movable bracket 271 is fitted to the stopper 273.

The rotating disk 3 has a disk shape, and a mounting portion 35 to the output shaft 52 of the driving device 5 is projected from the center portion. The rotating disk 3 is fixed to the output shaft 52 via the mounting portion 35, receives the rotation of the motor 51 decelerated by the decelerating mechanism 53 of the driving device 5, and rotates in the circular recess 21 described above.

The rotating disk 3 has a plurality of guide holes 31 (eight in the present invention) formed on a circumference centered on the rotation center. A spiral inclined surface 36 is formed on the surface side of the guide hole 31 so that the coin C can be easily drawn into the guide hole 31. Further, a coin pressing wall 33 is provided on the rear surface 32 so as to project from the periphery of the guide hole 31 in a curved direction in the counter-rotating direction.

The coin pressing wall 33 formed on the back surface 32 of the rotating disk 3 forms a coin pressing surface 331 that is developed in a slope shape in the counter-rotating direction from the periphery of the guide hole 31. The coin pressing surface 331 is formed with a certain slope. In this slope, the coin C is moved outward along the coin pressing surface 331 of the coin pressing wall 33 by the centrifugal force generated by the rotation of the rotating disk 3, and the coin C is first fixed to the fixed shaft 26 and the movable shaft 27. A range (contact points P2 and P3) until the contact is formed in an involute curve in the counter-rotating direction from the periphery of the guide hole 31 is formed.

As shown in FIG. 5, the contact point between the coin pressing surface 331 of the coin pressing wall 33 and the coin C is P1 (p1, p2,... P8), the contact point P2 between the coin C and the fixed shaft 26, and the coin C. When the contact point P3 of the movable shaft 27 is assumed, the slope of the coin pressing surface 331 from the involute curve to the tip side (the outer peripheral side of the rotating disk 3) is the contact point between the coin pressing surface 331 of the coin pressing wall 33 and the coin C. It is formed with a slope composed of a locus drawn by P1. First, as the rotary disk 3 rotates, the coin C moves along the involute curve of the coin pressing wall 33 and eventually comes into contact with the contact point P2 of the fixed shaft 26 and the contact point P3 of the movable shaft 27. At this time, the normal line NN set at the contact point P1 between the coin pressing wall 33 and the coin C is set so as to be positioned between the center O1 of the fixed shaft 26 and the center O2 of the movable shaft 27. Next, the contact point P1 of the coin pressing wall 33 with the coin pressing surface 331 is moved in the coin releasing direction (outward) on the normal line (that is, the coin C is inserted between the fixed shaft 26 and the movable shaft 27). ) And the pressing shaft sequentially moves the movable shaft 27 to further push the coin C outward. At this time, the contact point P <b> 1 with the coin pressing wall 33 moves along a certain locus in the outer circumferential direction of the rotary disk 3. A slope of the coin pressing surface 331 of the coin pressing wall 33 is formed along this locus.

In this way, the contact point P3 between the coin C and the movable shaft 27 moves, and the contact point P3 between the coin C and the movable shaft 27 is outward from the line connecting the center O1 of the fixed shaft 26 and the center O2 of the movable shaft 27. The coin C is discharged outward by the restoring force of the movable shaft 27 when it reaches the position (dead point Dp).

Note that the curve of the coin pressing surface 331 of the coin pressing wall 33 varies depending on the diameter, positional relationship, interval, size of the coin C, and the like of the fixed shaft 26 and the movable shaft 27. What is necessary is just to generate the pressing force for pushing between between and the movable shaft 27. Therefore, it is not limited to a curved line, and an inclined straight line may be used. Further, the direction of the normal NN (the position of the first contact point P1 between the coin C and the coin pressing surface 331) is changed (the position of the first contact point P1 between the coin C and the coin pressing surface 331). By doing so, it is possible to change the coin C discharge direction in the range between the fixed shaft 26 and the movable shaft 27.

The coin hopper 4 is formed with an insertion port 41 for coins C on the upper side and a discharge port 42 for supplying coins C to the rotary disk 3 on the lower side. Reference numeral 43 denotes an overflow passage through which the coin C overflowed in the coin hopper 4 flows to the outside. An engagement hook 44 for detachably attaching the coin hopper 4 to the base plate 2 is provided at the upper and lower edges of the discharge port 42. Then, the coin hopper 4 fits the engagement hook 44 on the lower edge side into a hole 28b formed on the lower edge of the base plate 2, rotates the portion as a fulcrum, and moves the engagement hook 44 on the upper edge side. It press-fits into a hole 28a formed in the upper edge of the base plate 2. By this press-fitting, the crank-shaped locking lever 29 is pushed upward obliquely, and when the press-fitting is completed, the locking lever 29 is restored, and the coin hopper 4 is mounted on the base plate 2. When it is necessary to remove the coin hopper 2 for some reason, the locking lever 29 is lifted obliquely upward, the engagement state with the engagement hook 44 is released, and the lower edge is rotated as a fulcrum to remove it.

The drive device 5 includes a motor 51 and an output shaft 52 that rotates via a speed reduction mechanism 53, is attached to the back surface of the base plate 2, and is housed inside the base member 1 by attaching the base plate 2 to the base member 1. The The output shaft 52 penetrates from the base plate 2 to the surface side, and fixes the rotating disk 3.
