Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial application field of the present invention> The present invention is used in an apparatus that uses only specific coins, such as a public telephone, for selecting and storing specific coins. About.

<Prior art> For example, coins that can be used in public telephones are 10 yen coins and 10 yen coins.
Since the coin is a zero-yen coin, the coin insertion slot is sized to accept a large-diameter 10-yen coin.

In this type of public telephone, among the inserted coins, 10-yen coins and 100-yen coins are sorted and stored separately, and each time a billing signal is input, the stored coins are stored in a safe. .

FIG. 5 shows a schematic structure of a coin processing device 1 provided in a public telephone for selecting and storing inserted coins.

The coin processing apparatus 1 rolls coins received by a coin receiving portion 3 at the upper right corner of a main substrate 2 formed of plastic or the like on a sorting orbit 4 formed with ribs on one surface 2a of the main substrate 2. To the first sorting mechanism 5.

The first sorting mechanism 5 performs sorting by utilizing the difference in the outer diameter of coins, and is configured as shown in FIG.

That is, the coins from the sorting track 4 are guided on the inclined surface 6a of the lower support plate 6 provided on the extension thereof.

Above the lower support plate 6, an upper support plate 7 slightly touching the upper edge of the back side of the 10-yen coin C (10) advancing on the lower support plate 6,
The middle support plate 8 which is in contact with the central portion on the front side of the coin is arranged in parallel.

Therefore, when a coin having a diameter of 10 yen or more invades from the sorting track 4, the coin is in a state of being supported at three points by each support plate, and passes through in the direction of arrow A as it is,
When a coin smaller in diameter than the 10-yen coin enters, the support by the upper support plate 7 is not obtained, and during rolling, the coin tilts toward the one surface 2a side of the main substrate 2 and an arrow from the inclined surface 6a of the lower support plate 6 Since it slides in the direction B and falls, it is possible to sort out 10-yen coins from other coins.

As shown in FIG. 5, the coins passing through the first sorting mechanism 5 are transferred to a first storage orbit 10 formed up to the lower end of the main substrate 2.
It rolls on the top and comes into contact with the storage gate 11 and the return gate 12, which are arranged at the ends, and stops.

In addition, coins that are sorted and dropped by the first sorting mechanism 5 roll on the sorting track 13 and are guided to the second sorting mechanism 14.

The second sorting mechanism 14 is formed in the same manner as the first sorting mechanism 5, and allows only coins having a diameter of 100 yen coin C (100) or more to pass, and drops coins smaller in diameter than the 100 yen coin. .

Coins passing through the second sorting mechanism 14 are stored in the first storage orbit.
It rolls on the second storage track 15 formed along the inside of 10 and stops in a state of contact with the storage gate 16 and the return gate 17.

In addition, coins that are sorted and dropped by the second sorting mechanism 14 are dropped and discharged from the return port 19 at the lower right corner of the main board 2 via the circular leg orbit 18.

When the storage gates 11 and 16 are moved by a billing signal or the like, the leading coins of the accumulated coins are discharged to the discharging unit 20.
, And are stored in a safe (not shown).

The coins stored on the first and second storage orbits 10 and 15 are also returned to the discharge unit 19 when the return gates 12 and 17 are moved by the on-hook operation. .

When an unsuitable coin such as a one-yen coin or a five-yen coin is inserted into the coin processing device 1 configured as described above, the unsuitable coin is passed through the first and second sorting mechanisms 5 and 14. Discharge section
When a 10-yen coin or a 100-yen coin is inserted from 19, it is accumulated in the first or second accumulation orbits 10 and 15 in order, a collection process for each predetermined call time, and a coin at the end of the call Return processing is performed.

<Problem to be solved> However, in the coin processing apparatus having the above-described configuration, the sorting trajectory has two stages, and the return trajectory and the first and second storage trajectories must be formed below the sorting trajectory. Without
Inevitably, the vertical dimension of the device becomes large.

Particularly in recent years, in order to respond to miniaturization of public telephones and diversification of designs, miniaturization of this type of coin processing device is strongly required. However, it has been difficult to reduce the size of the coin while maintaining the proper number of coins and the accuracy of sorting.

A second accumulation track formed toward the lower end of one end of the substrate, and provided at a position where the coin collides with a coin that has entered the opposite surface of the substrate, and only when a predetermined force or more is applied to the substrate. The other end of the substrate is urged to rotate to the other end side and guides the colliding coin to the second return trajectory when the collision force of the coin is smaller than a predetermined value, and receives the collision force larger than a predetermined value.

When the diameter of the entered coin is smaller than the first specific coin, the sorting mechanism tilts the coin on the orbit and slides it down to drop it on the first return trajectory.
When it is equal to or more than the specified coin, the coin is passed to the second sorting mechanism. When the diameter of the entered coin is smaller than the second specific coin, the second sorting mechanism tilts the coin on the orbit and slides it down to drop it on the first accumulation track, and the diameter of the entered coin is the second coin. When the number of coins is equal to or more than the specified coin, the coin is passed to the guiding mechanism and guided to the opposite side of the substrate. The coin guided to the opposite side of the substrate by the guide mechanism receives the magnetic force of the magnet and collides with the selection lever. The sorting lever rotates to the other end of the substrate when the coin collides with a predetermined or greater collision force, and a second lever formed on the opposite surface of the substrate so as to overlap the coin with the first accumulation track.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a main part of the coin processing apparatus according to one embodiment from one surface side, and FIG. 2 is a diagram showing the main portion of the coin processing device from the opposite surface side. A frame plate 31 forming an outer surface of a housing of the device is integrally formed of synthetic resin such as plastic.

This coin processing device is attached to a public telephone, as in the above-described conventional device, and is configured to be able to sort and accumulate 10-yen coins and 100-yen coins as usable specific coins.

In FIG. 1, coins inserted from a coin receiving slot 32 at the right corner of the main board 30 where the frame plate 31 is missing are placed on one side of the main board 30.
It is guided on the sorting track 33 formed obliquely on the 30a side.

The sorting track 33 is constituted by a track rib 34 protruding from the main substrate 30, and the inserted coin abuts on a step 35a of a rib 35 formed on the upper stage of the track rib 34, and the speed at the time of insertion is reduced. After being weakened, it rolls on the sorting orbit 33 and proceeds to the first sorting mechanism 36.

The step portion 35a uses the mechanical sorting method described above in which the sorting mechanisms 36 and 37 described below are used, and the sorting accuracy is to eliminate the drawback that the coin rolling speed decreases as the coin rolling speed increases. .

As described above, the first sorting mechanism 36 uses the 100-yen coin C (1
00) Only coins having the above-mentioned diameters are passed at the three-point support and advanced to the second sorting mechanism 37, and coins smaller in diameter than 100-yen coins, ie, 1-yen coins C (1) and 5-yen coins C (5), 50
It is configured to drop the yen coin C (50) downward.

The second sorting mechanism 37 is configured to pass only coins having a diameter of 10 yen coin or more with three points of support, and to drop coins smaller in diameter than the 10 yen coin downward.

Below the first sorting mechanism 36, there is provided a first return orbit 38 formed at an inclination opposite to that of the sorting orbit 33, and the returned coin rolls on the first return orbit 38. And the main board 30
To the return port 39 in the lower right corner.

At the lower stage of the first return track 38, a first storage track 40 for storing coins (100 yen coins) sorted and dropped from the second sorting mechanism 37 is formed along the first return track 38. I have.

At the end of the first storage track 40, an L-shaped gate member 41 is disposed.

As shown in FIG. 3, the gate member 41 is used to store the rolling coins in the storage gate plate connected to the first storage track 40.
42 and the return gate plate 43 rising from the storage gate plate 42. When storing coins, the coins are moved in the direction of arrow C by the action of a solenoid or the like (not shown) to store coins from the slits 42a of the storage gate plate 42. When coins are returned, they move in the direction of arrow D to return coins, and return coins.
From the slit 43a to the return port 39.

On the slightly lower left side of the second sorting mechanism 37, coins (10) passing through the second sorting mechanism 37 and traveling in the extension direction of the sorting orbit 33
A guide mechanism 45 for guiding the coin (coin) to the opposite surface of the main board 30 is provided in a protruding manner.

As shown in the IV-IV end view of FIG. 4, the guiding mechanism 45 is provided with a “shape” from the opposite surface 30b side of the main board 30 to the one surface 30a side, and coins are formed on the opening surface 45a generated by the step. To the opposite surface 30b of the main substrate 30.

Reference numeral 46 denotes a fake coin attracting magnet that reduces the speed of fake coins made of iron or the like that have passed through the second sorting mechanism 37 by a magnetic force.

Further to the left side (in FIG. 1) of the guide mechanism 45, a selection lever 48 that is rotatable around an upper rotation shaft 47 is attached.

The upper end 48a of the selection lever 48 is attracted to the circular magnet 49.

In the lower portion 48b of the selection lever 48, a collision piece 48c projecting to a position where the guide mechanism 45 collides with a coin that has advanced to the opposite surface 30b of the main substrate 30, as shown in FIG.
Is provided so as to penetrate through.

The attraction between the circular magnet 49 and the selection lever 48 is a regular
It is released only when a 10 yen coin collides with the collision piece 48c, 10
If a coin lighter than a yen coin or a fake coin whose speed has been reduced due to the attraction of the magnet 46 collides, the fake coin is not released.
Is guided on a second return orbit 50 formed on the opposite surface 30b of the vehicle, and is discharged from the return port 51.

At the lower stage of the second return orbit 50, a second storage orbit 52 for rotating the selection lever 48 to accumulate the regular 10-yen coin C (10) that falls downward is provided in the first storage orbit 40. Are formed so as to overlap with each other.

At the end of the second storage orbit 52, the first storage orbit 40
Similarly to the above, a gate member 55 in which the storage gate plate 53 and the return gate plate 54 are integrated is disposed, and when coins are stored, the accumulated leading coins fall into the storage opening 56 by the action of a solenoid (not shown). At the time of coin return, the accumulated coins are guided to the return port 51.

 Next, the operation of this device will be described.

When a 100-yen coin, which is one of the specific coins, is inserted from the coin receiving slot 32, the coin passes through the first sorting mechanism 36, falls down by the second sorting mechanism 37, and drops in the first storage orbit. It rolls on 40 and comes into contact with the gate member 41 and stops.

Further, when 100-yen coins are continuously inserted, the inserted 100-yen coins are sequentially accumulated on the first accumulation orbit 40. However, a predetermined number (for example, 4) or more of the inserted coins The vehicle cannot enter the first storage track 40 and rolls on the first return track 38 to be returned.

Here, along with the connection of the line or the generation of a billing signal during a call, the 100-yen coins stored in the first storage track 40 are sequentially dropped into the storage port 44, and when the line is disconnected,
The remaining coins are sent to the return port 39.

When a 10 yen coin is inserted, the inserted 10 yen coin is
It passes through the first and second sorting mechanisms 36 and 37, is sent to the opposite surface 30b side of the main substrate 30 by the guiding mechanism 45, collides with the collision piece 48c of the sorting lever 48, and rotates the sorting lever 48, It rolls on the second accumulation track 52, contacts the gate member 55, and stops.

When 10-yen coins are continuously inserted in the same manner as described above, the inserted coins are sequentially accumulated on the second accumulation orbit 52. However, predetermined coins (for example, 5 coins) or more are accumulated in the second return orbit 50. Will be returned via

The 10-yen coins thus accumulated are stored in the storage slot 56 in sequence with the connection of the line and the generation of the billing signal as described above.
And the remaining coins are sent to the return port 51 due to the line disconnection.

Inappropriate coins and fake coins such as 1 yen, 5 yen, and 50 yen are produced by the action of the first sorting mechanism 36 or the sorting lever 48.
Unconditionally sent to the first and second return orbits 38 and 50, return port
Returned from 39, 51.

Further, in this embodiment, only the main substrate 30 constituting the main part of the coin processing apparatus has been described. However, actually, cover members are attached to both surfaces of the main substrate 30 to prevent the coin from deviating from the orbit. Needless to say, the description is omitted.

<Other Embodiments of the Present Invention> In the above-described embodiment, the case has been described in which two types of specific coins that can be used are a 10-yen coin and a 100-yen coin.
When there are three types of specific coins, the present invention is applied to two types of specific coins, and the accumulation trajectory of the remaining specific coins may be formed on one side of the main board. It is not limited to the case.

In the above embodiment, coin sorting is performed by a mechanical method utilizing the difference in outer diameter. In addition to this mechanical method, for example, electronic sorting (difference in magnetic permeability) at the end of the storage orbit. Is detected by an oscillation circuit or the like) to improve the sorting accuracy.

<Effect of the Present Invention> As described above, the coin processing device of the present invention is configured to accept a coin received in a sorting track from an upper end of one end of a substantially vertical substrate,
Rolling toward the other end of the substrate, the first sorting mechanism having a trajectory continuous with the sorting trajectory tilts a coin having a diameter smaller than the first specific coin so as to be separated from the substrate, thereby forming a first lower coin. To a return trajectory, a coin having a diameter equal to or larger than the first specific coin is passed to a second sorting mechanism having a trajectory continuous with the trajectory of the first sorting mechanism, and a coin having a smaller diameter than the second specific coin Is tilted away from the substrate and slides down into the first accumulation track below, and passes a coin having a diameter equal to or larger than the second specific coin to the guiding mechanism while receiving the magnetic force of the magnet, and on the opposite side of the substrate The coin is guided and collided with the sorting lever, and the coin that has collided with a predetermined or greater collision force is guided to a second accumulation track formed on the opposite surface of the substrate so as to overlap the first accumulation track, and is smaller than a predetermined value. The coins collided by the collision force are returned to the first return trajectory. And it is configured to guide the second return track formed on the opposite side of the substrate so as to overlap.

For this reason, the size of the apparatus, particularly the vertical dimension, can be remarkably reduced without lowering the sorting accuracy and the number of stored sheets as compared with the case where the storage track is provided on one surface side of the substrate as in the related art.
