DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a public telephone which stores a leading coin one by one among a plurality of coins accumulated in a coin accumulating orbit in order to collect a usage fee by coins. The present invention relates to a coin holding device for temporarily holding a succeeding coin.

[0002]

2. Description of the Related Art As a conventional coin holding apparatus of this kind, there is an apparatus disclosed in Japanese Utility Model Publication No. 3-48888 filed by the present applicant. This device presses the side of the following coin to the track plate side with the tip of the pressing member to which the pressing force is always applied when storing the leading coin from the coin storage track where a plurality of coins are stored. The coins are temporarily held, and only the open top coin is dropped into the coin storage slot repeatedly to store the coins one by one.

In such a coin holding device, when holding a plurality of types of coins having different diameters, the side surface of the coin is pressed. There is an advantage that the coin can be stably held irrespective of the diameter of the coin, as compared with a coin holding device of a type that prevents and holds the rolling of the coin.

[0004]

However, such a coin holding device that presses and holds the side surface of a coin has to press the center of the side surface of each coin with a pressing member to hold the coins of the third and subsequent coins. The weight and impact may cause the second coin to be displaced from the tip of the pressing member, making it impossible to hold the coin. For this reason, it is difficult to accumulate coins having significantly different diameters in the same accumulation orbit, and it has been limited to a plurality of types of coins having a diameter difference.

In order to press the center of the coin with the pressing member, the mounting position of the coin holding device is restricted, and the position adjustment is delicate, resulting in an increase in manufacturing cost. Further, in order to press and hold the side surface of the coin by the pressing member, a pressing force is needed to resist the weight of the stored coins, and therefore, the power consumption of the electromagnet driving the pressing member also increases the number of stored coins. As the number increased, the power saving of electromagnets was limited.

The present invention has been made in view of such circumstances, and it is not necessary to adjust a mounting position for a plurality of types of coins having different diameters, and it is possible to reliably hold a succeeding coin when a leading coin is ejected. Moreover, it is an object of the present invention to provide a coin holding device that saves power.

[0007]

SUMMARY OF THE INVENTION A coin holding device according to the present invention holds any of several types of coins having different diameters at two spaced points on the circumference of the coin in the radial direction. A rotating disk 2 having such supporting means 4 and a control means 6 for controlling the rotating operation of the rotating disk 2. The rotating axis of the rotating disk 2 is orthogonal to the coin surface, and A line connecting the center of rotation of the board 2 and two points of the support means 4 which are in contact with two points on the circumference of the coin is V-shaped.

[0008]

With the coin holding device constructed as described above,
When the leading coin is stored, when the turntable 2 is made rotatable by the control means 6, a force in the rotation direction is applied to the turntable 2 by the weight of the coin supported by the support means 4, and the turntable 2 is rotated. Then, the leading coin rolls into the coin storage slot. At this time, the subsequent coin also slightly rolls due to the rolling of the leading coin, but immediately, the support means 4 and the two points on the periphery of the coin abut, and the coin is supported in the radial direction. When it comes to a certain position, the rotation of the turntable 2 stops.
Therefore, the subsequent coin remains held at that position.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a coin holding device according to an embodiment, in which a track cover 1 covering the surface of a track plate 1a forming an accumulation track 1 is shown.
2B is a schematic diagram viewed from the front side with b removed, and FIG. 2 is a schematic diagram of the apparatus of the embodiment viewed from the back side of the track plate 1a. FIG. 3 is a sectional view taken along line AA of the schematic diagram of FIG.

The coins C1, C2, C3 inserted from a coin insertion slot (not shown) are stored in the storage orbit 1 after being sorted by a coin sorting device (not shown).
At a position slightly lower than the end of the storage track 1 of the track plate 1a,
A circular hole is provided, and the turntable 2 is provided so as to be fitted into the circular hole. A rotating shaft 3 is integrally formed at the center of the rotating disk 2, and the rotating shaft 3 is formed by a track cover 1b and an angle 1c fixed to the track plate 1a.
Is supported. Cross-shaped blades 4a, 4b, 4c, 4d that are in contact with and support the coin C1
Is integrally formed with the turntable 2 so as to protrude into the storage track 1. The rotating operation of the turntable 2 is performed by four concave portions 5 provided on the back side of the turntable 2.
It is controlled by a control means 6 having a substantially square cam 5 having a, 5b, 5c and 5d. The cam 5 is formed integrally with the turntable 2 in the same manner as the support means 4. The rotating disk 2, the rotating shaft 3, the supporting means 4, the cam 5
Describes an example of integrally molding as a molded product,
Instead of molded products, they may be formed by a method such as bonding together by means such as bonding.

On the other hand, as control means 6 other than the cam 5, the fork-like engaging pieces 7a and 7b
A rotation control lever 7 having The rotation control lever 7 is rotatably supported on the track plate 1 a by a support shaft 8. The rotation control lever 7 is normally pulled in the direction of arrow A in FIG. The engagement piece 7a of the rotation control lever 7
The electromagnet 10 is provided on the side opposite to the side 7b.
When the electromagnet 10 is excited, the electromagnetic lever 11 is displaced. The displacement force of the electromagnetic lever 11 is transmitted to the rotation control lever 7 via the pin 12.

Therefore, as main components of the control means 6, the electromagnet 10, the rotation control lever 7, and the cam 5 are provided. Next, the operation of the coin holding device thus configured will be described. First, electromagnet 1
2 is not excited, the engagement piece 7a of the rotation control lever 7 is actuated by the spring 9 as shown in FIG.
Is pulled in the direction of arrow A in (a), so that the rotation control lever 7 rotates about the support shaft 8 in the direction of arrow B,
The engagement piece 7a engages with the concave portion 5a of the cam 5 to prevent the rotation of the turntable 2. In this state, the cross-shaped blades 4a of the support means 4 provided on the surface side of the turntable 2 are in the state shown in FIG. 1, and the leading coins C1 are adjacent to the blades 4a, 4b.
As a result, the coin is radially held at two spaced points on the circumference of the leading coin C1. At this time, the rotation axis of the rotating disk 2 is orthogonal to the plane of the coin C1, and the adjacent blades 4
A line connecting two points where a and 4b are in contact with the coin C1 and the rotation center of the turntable 2 is V-shaped. The subsequent coin C2 is
Since the coin is in contact with the outer periphery of the leading coin C1 and the leading coin C1 is held, the subsequent coins after the second one are also accumulated and held in the accumulation orbit 1.

When a coin storage signal arrives at the public telephone and the electromagnet 10 is excited to store coins, the electromagnetic lever 11 is displaced from the state shown in FIG. 2A to the state shown in FIG. Is transmitted to the rotation control lever 7 via the pin 12. Then, the rotation control lever 7 overcomes the pulling force of the spring 9 and is rotated about the support shaft 8 in the direction of arrow C. When the rotation control lever 7 rotates in the direction of arrow C,
The engagement between the engagement piece 7a and the concave portion 5a of the cam 5 is released, and the turntable 2 is opened. Further, in this state, when the engaging piece 7b pushes the protruding portion 5e adjacent to the concave portion 5d of the cam 5, the turntable 2 starts to rotate, whereby the rotary plate 2 is supported by the blades 4a and 4b of the support means 4. Top coin C
Since the weight of 1 will be added to the rotation direction as it is,
Thereafter, the turntable 2 is rotated by the weight of the leading coin C1,
It rotates until the leading coin C1 comes off the blade 4a and falls into the coin storage slot. Therefore, the rotation of the electromagnet 10 can be controlled by driving the rotation control lever 7 because the operation of disengaging the engagement piece 7a from the recess 5a of the cam 5 and the operation of instantaneously applying the initial rotational force of the turntable 2 can be performed. The excitation can be instantaneous, and the power consumption for the excitation is small.

When the leading coin C1 falls into the coin storage slot, the turntable 2 has rotated 90 degrees, and is again in the same state as (a), and the engaging piece 7a and the recess 5b of the cam 5 are engaged. At the same time, the turntable 2 stops at that position and is prevented from rotating any further. The subsequent coin C2 moves as the leading coin C1 starts to move, but the rear blade 4d supporting the leading coin C1 moves the leading coin C1 and the trailing coin C2 with the rotation of the turntable 2. At the position where the rotation of the turntable 2 is stopped, the subsequent coin C2 does not roll any more, and the rear blade 4d and the further rear blade 4c adjacent thereto are not rolled. As a result, the coin is held in the radial direction at two spaced points on the circumference like the leading coin C1. In this way, the coin storage signal comes and the electromagnet 10
Each time is excited, the turntable 2 rotates and holds the following coins, and the leading coins can be reliably discharged one by one.

FIG. 4 shows that regardless of the size of the coin diameter,
It is the schematic explanatory drawing which looked at the surface side of the track plate by removing the track cover which shows that the leading coin can be reliably discharged one by one, holding the succeeding coin. (A) of FIG.
(C) shows a case where small-diameter coins are accumulated in the accumulation orbit 1, (a) shows a state before the electromagnet 10 is excited,
(B) is a state in which the rotating disk 2 is rotating while the electromagnet 10 is momentarily excited. (C) is a state in which the leading coin falls from the support means 4 and the engaging piece 7a and the concave portion 5b of the cam 5 are engaged. And the rotation of the turntable 2 is stopped. (D) of FIG.
(F) shows a case where large-diameter coins are accumulated in the accumulation orbit 1, (a) shows a state before the electromagnet 10 is excited,
(B) is a state in which the rotating disk 2 is rotating while the electromagnet 10 is momentarily excited. (C) is a state in which the leading coin falls from the support means 4 and the engaging piece 7a and the concave portion 5b of the cam 5 are engaged. And the rotation of the turntable 2 is stopped. From the diagrams showing the respective states in FIG. 4, it can be seen that the leading coin can be reliably discharged one by one while holding the subsequent coin regardless of the size of the coin.

Next, another embodiment of the present invention will be described. In the above embodiment, the control means 6 is used as the cam 5
5, a plurality of pins 13a to 13d are provided on the back side of the rotary disk 2 in place of the cam 5, as shown in FIG. Instead, a rotation control lever 1 having engagement pieces 15a and 15b having a substantially symmetrical shape that rotates about a rotation shaft 14
5 are provided.

In the state shown in FIG. 5A, the coin is held because one engagement piece 15b of the rotation control lever 15 is engaged with the pin 13a to prevent the rotation of the turntable 2. . Excitation of the electromagnet etc. by the coin storage signal and the rotation axis 1
4 is rotated clockwise, as shown in (b), the engagement between one of the engagement pieces 15b of the rotation control lever 15 and the pin 13a is released, and the turntable 2 becomes rotatable. The rotation force is applied to the pin 13a by the engagement piece 15a, so that the turntable 2 starts rotating and starts discharging the leading coin.

When the turntable 2 rotates about 90 degrees and the rotation control lever 15 returns to the state shown in FIG.
3b is engaged with the engagement piece 15b of the rotation control lever 15, so that the rotation of the turntable 2 is stopped and stops at that position. The operation of the support means on the front side of the turntable 2 in the above state is the same as that of the above-described embodiment, and the description is omitted. With such a configuration, the pin 13 only needs to be erected on the turntable 2 as compared with the cam 5, so that it is easier to manufacture.

As still another embodiment, an example in which the shape of the support means 4 provided on the front side of the turntable 2 is variously modified as shown in FIG. 6 will be described. FIG. 6A shows that a V-shaped concave portion 16 is formed on the front side of the turntable 2 so that only one coin can be supported. Opening angle α of recess 16
The angle may be any angle at which the accumulated coins can be supported at two points. 3B, three pins 17 are provided on the surface of the turntable 2 and one place for supporting a coin is provided in the same manner as in FIG. (C) is a modification of (b),
A plurality of projections 18 are provided on the surface of the turntable 2 so that coins can be supported at two points. (D) is the blade 19 of the support means 4 formed in a Y-shape. In this case, as can be seen from the figure, there is an advantage that the coin can be securely held even when the difference between the diameters of the coins is significant. (E) is the blade 19 of (d).
Instead, a pin 20 is set up. (F) is a coin which can be held at four places as in the first embodiment described above. A plurality of pins 21 are set up on the surface of the turntable 2 instead of the blades. As can be seen from the above embodiment, the support means and the control means of the present invention can be variously modified without departing from the scope of the present invention.

[0020]

As described above, the coin holding device according to the present invention can be used for any of several types of coins having different diameters at two spaced points on the circumference of the coin in the radial direction. A rotating disk having supporting means for holding the disk, and a control means for controlling the rotating operation of the rotating disk. When storing the leading coin, the rotating disk is made rotatable by the control means and the initial rotational force is set. Is given instantaneously, thereafter, the force of the rotation direction is applied to the turntable due to the weight of the coin supported by the support means, and the turn starts rotating, and the leading coin rolls into the coin storage slot, but at the same time the subsequent coin is supported. Hold by means,
Even if the difference in the diameters of coins that can be stored is large, subsequent coins can be reliably held when the leading coin is ejected.

Further, unlike the conventional apparatus, fine adjustment of the mounting position of the coin holding device is not required. Further, since the driving energy required by the control means for controlling the rotating operation of the turntable can be reduced, there is an advantage that when incorporated in a public telephone or the like, power consumption can be reduced irrespective of the number of accumulated coins. .
