As shown in FIG. 5, the rotational force transmission portion 23 includes a connecting shaft 23a. The rotary plate 21 is connected to the connecting shaft 23a. The connecting shaft 23a is rotated by the rotational driving force of the motor M (see FIG. 3). As a result, the rotating plate 21 rotates together with the connecting shaft 23a.

The coin ejection device 20 further includes a stirring sheet 26 , a support base 27 and a fixing member 28 .

The stirring sheet 26 stirs the coins in the first chamber 1Aa. The stirring sheet 26 is a sheet-like member. The stirring sheet 26 is made of, for example, resin such as Polyslider (registered trademark) or metal. The stirring sheet 26 has a thickness of about 0.5 mm, for example. The stirring sheet 26 is arranged between the support base 27 and the fixing member 28 . The stirring sheet 26 is arranged above the rotating plate 21 . Specifically, the tip 26 a of the stirring sheet 26 is arranged above the rotating plate 21 . A tip portion 26 a of the stirring sheet 26 protrudes from between the support base 27 and the fixing member 28 .

The support base 27 supports the stirring sheet 26 . The support base 27 is fixed to the coin storage box 10 . Note that the support base 27 may be configured integrally with the coin storage box 10 .

The fixing member 28 detachably fixes the stirring sheet 26 to the support base 27 by sandwiching the stirring sheet 26 with the support base 27 . The fixing member 28 is a plate-like member. The fixing member 28 is made of resin, for example.

The stirring sheet 26 will be further described with reference to FIGS. 8 and 9. FIG. FIG. 8 is a plan view showing the positional relationship between the rotating plate 21 and the stirring sheet 26. As shown in FIG. FIG. 9 is a sectional view showing the positional relationship between the rotating plate 21 and the stirring sheet 26. As shown in FIG.

As shown in FIGS. 8 and 9, the rotating plate 21 rotates around the rotation axis H. As shown in FIGS. The plurality of coin holes 21b are arranged in a direction around the rotation axis H with the rotation axis H as the center.

When viewed from the axial direction of the rotating shaft H, the leading end (lower end) 26a of the stirring sheet 26 is positioned on the locus of rotation of the coin hole 21b. Also, when viewed from the axial direction of the rotating shaft H, when the rotating plate 21 rotates, the tip portion 26a of the stirring sheet 26 passes through the coin hole 21b. The axial direction of the rotation axis H is the direction in which the rotation axis H extends.

In FIG. 8, a dotted line W1 indicates a circle formed around the rotation axis H and passing through the centers J of all the coin holes 21b. A dotted line W2 indicates a circle formed around the rotation axis H so as to surround all the coin holes 21b.

As seen from the axial direction of the rotating shaft H, the tip 26a of the stirring sheet 26 passes through the region between the dotted lines W1 and W2 on the rotating plate 21 when the rotating plate 21 rotates. That is, the area between the dotted line W1 and the dotted line W2 shows the trajectory of the leading end portion 26a of the stirring sheet 26 passing over the rotating plate 21 when the rotating plate 21 rotates when viewed from the axial direction of the rotating shaft H.

In FIG. 8, the first distance X1 indicates the distance between the rotating shaft H and the coin hole 21b when viewed from the axial direction of the rotating shaft H. As shown in FIG. The second distance X2 indicates the distance between the rotating shaft H and the tip portion 26a of the stirring sheet 26 when viewed from the axial direction of the rotating shaft H. As shown in FIG. A difference X3 between the second distance X2 and the first distance X1 when viewed from the axial direction of the rotation axis H is substantially the same as the radius of the coin hole 21b. As a result, when viewed from the axial direction of the rotating shaft H, when the rotating plate 21 rotates, the leading end portion 26a of the agitating sheet 26 covers a part of the coin hole 21b (specifically, substantially half of the area). pass through. In FIG. 8, a hatched region α is a region of the coin hole 21b through which the leading edge 26a of the agitating sheet 26 passes when the rotating plate 21 rotates when viewed from the axial direction of the rotating shaft H. indicates

In FIG. 9, the tilt angle θ indicates the tilt angle of the stirring sheet 26 with respect to the upper surface 21a of the rotating plate 21. In FIG. Further, the agitating sheet 26 is located on the side where the upper end of the agitating sheet 26 is further away from the rotating shaft H than the lower end of the agitating sheet 26 when viewed from the side. The tilt angle θ is an acute angle. The inclination angle θ is preferably 25° or more and 45° or less. The tilt angle θ is more preferably about 35°.

A tip portion 26 a of the stirring sheet 26 is positioned at approximately the same height as the upper surface 21 a of the rotating plate 21 . Note that the tip portion 26a of the stirring sheet 26 may be arranged above the upper surface 21a of the rotating plate 21 by a predetermined dimension. The predetermined dimension is, for example, a dimension smaller than the dimension of the thickness of a coin. The tip portion 26a of the stirring sheet 26 is arranged at substantially the same height as the upper surface 21a of the rotating plate 21, or is arranged above the upper surface 21a of the rotating plate 21 by a predetermined dimension, so that the stirring sheet 26 rotates. It is possible to suppress entrapment between the plate 21 and the circular recess 11d (see FIGS. 4 and 5).

Above the stirring sheet 26, the slope portion 11c described with reference to FIGS. 4 to 7 is arranged. As a result, after the coins that have slid down from the slope portion 11c are dropped onto the agitation sheet 26, the inclination of the agitation sheet 26 allows the coins K to be smoothly guided onto the rotating plate 21. FIG.

The mounting structure of the stirring sheet 26 will be described with reference to FIG. FIG. 10 is an exploded perspective view showing the mounting structure of the stirring sheet 26. As shown in FIG.

As shown in FIG. 10, the support base 27 has an inclined surface 27a inclined at the same angle as the inclination angle .theta. of the stirring sheet 26 (see FIG. 9). The agitating sheet 26 is placed on the inclined surface 27a of the support base 27 so that it is inclined at an inclination angle θ.

A procedure for fixing the stirring sheet 26 to the support base 27 will be described.

First, the stirring sheet 26 is placed on the inclined surface 27a of the support table 27. As shown in FIG. Then, the stirring sheet 26 is sandwiched between the support base 27 and the fixing member 28 by covering the stirring sheet 26 on the inclined surface 27 a with the fixing member 28 . Then, in a state in which the stirring sheet 26 is sandwiched between the support table 27 and the fixing member 28, the fixing member 28 is fastened to the support table 27 with screws. As a result, the support base 27 and the fixing member 28 hold the stirring sheet 26 between them. As a result, the stirring sheet 26 is fixed to the support base 27 .

A procedure for removing the stirring sheet 26 from the support base 27 will be described.

The screw is removed from the state where the stirring sheet 26 is fixed to the support base 27 . As a result, the fastening state between the support base 27 and the fixing member 28 is released, so that the fixing member 28 and the stirring sheet 26 are removed from the support base 27 .

As described above with reference to FIG. 10, the stirring sheet 26 is detachably fixed to the fixing member 28 so as to be sandwiched between the stirring sheet 26 and the support base 27 . As a result, the stirring sheet 26 can be removed from the fixing member 28 by releasing the fastening state between the support base 27 and the fixing member 28, so that the stirring sheet 26 can be easily replaced.

[Regarding the operation of the coin ejecting device of the coin storing and dispensing device]
1, 5, 6, 7, and 11(a) to 12(b), a procedure for ejecting the coin K in the first chamber 1Aa by the coin ejection device 20 will be described. . 11(a) to 12(b) are diagrams showing procedures for ejecting the coin K in the first chamber 1Aa by the coin ejection device 20. FIG.

As shown in FIGS. 1, 5, 6, 7, and 11(a), the coin storing and dispensing device 1A is operated while the coin K is stored in the first chamber 1Aa of the coin storing and dispensing device 1A. When the motor M corresponding to 1A rotates, the rotational driving force of the motor M is transmitted to the rotating plate 21 via the drive gear G, the rotational force transmission portion 23, and the connecting shaft 23a. As a result, the rotating plate 21 rotates. In this embodiment, the rotating plate 21 rotates in the forward rotation direction (arrow B direction).

When the rotating plate 21 rotates, the coin K fitted in the coin hole 21b rotates together with the rotating plate 21. - 特許庁In this case, the coin K rotates together with the rotating plate 21 while being fitted in the coin hole 21b by the pressing force from the first contact surface portion 21c1 of the inner projecting rib 21c.

As shown in FIGS. 1, 5, 6, and 11(b), when the rotary plate 21 rotates, the coin K fitted in the coin hole 21b is positioned at the convex portions 24a and 24b. When it reaches the place where it does, it collides with the convex part 24a. On the other hand, the inner protrusion rib 21c passes between the protrusions 24a and 24b without colliding with the protrusions 24a and 24b.

As shown in FIGS. 1, 5, 6, 7, 12(a), and 12(b), the coin K that collides with the convex portion 24a moves toward the convex portion 24b. Further, the coin K continues to be pushed in the direction of the arrow B by the first contact surface portion 21c1 of the inner projecting rib 21c, so it moves toward the first discharge port 11b. As a result, the coin K is discharged from the first discharge port 11b to the coin dispensing port 104. As shown in FIG.

It should be noted that the contact of the convex portion 24a, the convex portion 24b, and the first contact surface portion 21c1 of the inner protrusion rib 21c with the coin K is line contact in the thickness direction of the coin K, and the first contact surface portion 21c1 Since the pressing force on the coin K acts in a direction in which the coin K is easily ejected toward the first discharge port 11b (in the direction of the arrow F), the coin K smoothly moves toward the first discharge port 11b.

Next, the operation of the coin ejection device 20 when the coin ejection device 20 does not include the stirring sheet 26 will be described with reference to FIGS. 5 and 13(a) to 13(c). 13(a) to 13(c) are schematic diagrams showing the operation of the coin ejection device 20 when the coin ejection device 20 does not include the stirring sheet 26. FIG.

As shown in FIGS. 13(a) to 13(c), a plurality of coins K are arranged over the upper surface, the coin hole 21b, and the bottom surface of the rotating plate 21, so that the coin hole 21b and the bottom surface are may be arranged so as to overlap while tilting diagonally. For example, a plurality of coins K are continuously dropped from the slope portion 11c (see FIG. 5) into the first chamber 1Aa, so that they are piled up on the coin hole 21b while being obliquely tilted. Also, a plurality of coins K lined up in a standing state are laid down by the stirring rod 30 (see FIG. 6), and are piled up while being obliquely tilted on the coin hole 21b. In this case, since a plurality of coins K protrude from the coin hole 21b, they cannot be discharged from the first discharge port 11b (FIG. 12(b)).

In addition, when a plurality of coins K overlap with the coin hole 21b while tilting with respect to the bottom surface, a gap is formed between the lowest coin K among the plurality of coins K and the bottom surface of the coin hole 21b. . As a result, the lowermost coin K among the plurality of coins K is less likely to come into contact with the convex portion 24a and/or the convex portion 24b (see FIG. 11(a)). As a result, the lowermost coin K is restricted from being guided by the protrusions 24a and/or the protrusions 24b and ejected from the first ejection port 11b.

Therefore, in this embodiment, the stirring sheet 26 is used to effectively perform the process of discharging the coins K. FIG.

Next, the operation of the coin ejection device 20 when the coin ejection device 20 includes the stirring sheet 26 will be described with reference to FIGS. 14(a) to 14(c) and FIG. 14(a) to 14(c) are schematic diagrams showing the operation of the coin ejection device 20 when the coin ejection device 20 includes the stirring sheet 26. FIG. FIG. 15 is a perspective view showing a state in which the uppermost coin K among the plurality of coins K has been scraped by the stirring sheet 26. As shown in FIG.

As shown in FIGS. 14(a) to 14(c) and 15, when the rotating plate 21 rotates, the coin K positioned at the uppermost layer among the plurality of coins K obliquely stacked on the coin hole 21b is rotated. is pressed by the pressure from the stirring sheet 26 and moves into the coin hole 21b. That is, the uppermost coin K among the plurality of coins K is scraped off by the agitating sheet 26, and is accommodated in the coin hole 21b.
