Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to public telephones, vending machines, and internal medicine.
The present invention relates to a mechanism for preventing unauthorized operation using string-suspended coins, which is suitable for use in a coin sorting device used in a coin sorting device.

[Conventional technology]

Generally, coin sorting devices are equipped with various sorting mechanisms to ensure that only genuine coins are used for device operation.
As a method of fraudulent use using genuine coins, there is a method of fraudulent use called so-called thread hanging. In this method, a hanging string or the like is fixed to one end of the coin using adhesive or other material, and the string is inserted through the coin slot, and the coin is retrieved by pulling through the string after the communication path or after taking out the product. , is typical of malicious non+E usage.

In order to prevent such unauthorized use of string-hung coins, for example, thread cutting means such as a cutter that can cut the hanging thread of string-hung coins may be provided at appropriate locations within the coin sorting track or the coin accumulation track. , or a person who can hold the hanging string of a string-hanging coin at an appropriate point on the above-mentioned track.
Various types of devices including h-P stages are conventionally known.

[151 problems that the invention attempts to solve] However,
[In the conventional double-stranded structure, since the thread cutting means and the tiers are provided in a fixed track, the hanging thread of the thread-hanging coin is caught and held by these.] This causes coins to jam in the track,
This had problems such as causing the main equipment itself to become inoperable. In addition, in the conventional structure described above, especially in the former case, not only does it lead to high costs, but also the sharpness of the knife deteriorates due to the nature of the knife, requiring frequent maintenance and inspection.
Replacement work is required, and it is desired that some kind of countermeasure be taken to solve these problems.

[Means to solve the problem]

In order to meet such demands, the tamper-proofing mechanism for string-suspended coins according to the present invention corresponds to the corner of the track bending part on the base plate constituting the coin track and the side plate that is openable and closable opposite the base plate. A pair of plate-like members are provided oppositely protruding from the portion, and the tips of these plate-like members are
The structure is such that a wedge-shaped groove is formed when the S plate and the side plate are placed opposite each other.

[Effect]

According to the present invention, when sorting coins, a wedge-shaped groove formed by a pair of plate-like members protruding from the base plate and the side plate is formed at the corner of the track bending part, and the hanging line of the string-suspended coins thrown into the groove is formed in the wedge-shaped groove. It can be clamped and held in place by a wedge action, and the hanging string held in this groove is held in place by a plate-like member that is separated by releasing the side plate from the board in conjunction with the coin return operation. The condition will be removed and the item will be returned.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail using embodiments shown in the drawings.

Figures 1 to 3 show an embodiment of the mechanism for preventing unauthorized operation using string-suspended coins according to the present invention. To explain briefly, the reference numeral 2 is a board installed in a substantially vertical position inside the housing of a device such as a public telephone.
A coin slot 3 is opened and provided on the upper end side. A flapper 5 as a side plate is pivotally supported on the upper end side of this board 2 via a support shaft 4, and a coin sorting track 6 is formed between these boards 2.79925. It is said to be composed of Here, this flapper 5 moves the track 6 so that when coins are returned, surplus coins located in the track 6 can be returned, and coins or foreign matter clogging can be removed from the track 6. It is for opening and closing, and is normally biased by a torsion spring (not shown) so as to form a track 6 parallel to and recessed for a predetermined distance with respect to the substrate 2. Furthermore, although not shown, the coin sorting track 6 is equipped with sensors for sorting coin materials, etc., and the downstream side of the track 6 is equipped with mechanical parts necessary for this type of device, including a coin storage track and a return track. It is also well known that the following are provided as appropriate.

Now, according to the present invention, in the coin sorting device 1 having a double-coin configuration, the coin sorting track 6 includes:
(At the portion corresponding to the corner portion 6b facing the track bending portion 6a of the plates 2 and 2 rampers 5, a pair of plate-like members 10
．． 11 facing each other.

A distinctive feature is that the tips of these plate-like members lo and 11 are configured so that a wedge-shaped groove 12 is formed when the flapper 5 that connects the ifi board 2 is closed (during normal coin sorting). have.

That is, the present invention is designed to prevent the hanging string 1 from being erroneously operated by the string-hanging coins 13 in the coin sorting device l.
The wedge-shaped groove 12 as an IF means that can engage the coins 4 in the track 6 is formed by the plate-like members 10 and 11 protruding from the base plate 2 and the flapper 5, respectively. This wedge-shaped groove moves 6 times during the closing operation!
12 can be opened, thereby allowing the hanging string 14 of the string-suspended coin 13 held in the groove 12 to be released and returned to the coin return section side, unlike the conventional coin rail 6. The structure is such that only 1 coin jam occurs.

Here, in this embodiment, the metal plate material is used as the substrate 2 and the flapper 5.
The mounting is fixed so that they face each other, and one end of the tip part is in contact with the side surface so that they are aligned in the east, and the other end is gradually separated, so that when viewed from the side, it has a roughly wedge-like shape. A case is shown in which the structure is such that a groove portion 12 is formed. In such a configuration, the wedge-shaped groove portion 12 can be appropriately formed in the cylinder by providing a simple plate material as is, which has advantages such as being advantageous in terms of moldability and cost.

According to the wedge-shaped groove portion 12 having such a configuration, when a string-suspended coin 13 is thrown in, the hanging string 14 can be bitten into it and held. , thereby stopping the string-suspended coin 13 on the tip side of the suspended string 14 in the middle of the trajectory 6,
This can prevent the thread-hanging coins 13 from entering the storage track side. In addition, when an unauthorized operator pulls the hanging line 14 from the outside with the hanging line 14 latched in the middle in this way, the pulling force causes the hanging line 14 to leave the part held between the wedge-shaped grooves 12. It will be easily understood that unauthorized manipulation of the thread-hanging coin 13 can be easily and appropriately prevented.

On the other hand, as described above, the hanging line 14 and the hanging coin 13 at the tip of the hanging line 14, which are tied in the wedge-shaped groove ff112 formed by the plate member 10.11, are removed by the coin return operation of the device.
When the flapper 5 is released from the plate 2, the IIvI section 12 is moved to the third
As the coin is released as shown in the figure, the related IF state is released and the coin is dropped and returned via the return track, etc., and the conventional problems such as coins getting jammed in the coin track are eliminated. The Rukoto.

Here, as the opening/closing mechanism by the coin return operation on the main device side of the flapper 5 mentioned above, for example, the actual opening/closing mechanism 57-tt
As shown in the Publication No. 44es Masu, etc., various structures are conventionally known.

For example, in public telephones, the 2-/flavor is activated when the handset is lifted down? The lever and link configuration may be such that the flapper 5 can be opened against the biasing force by the actuation force of the return lever in the case of a vending machine.

Note that the present invention is not limited to the structure of the embodiment described above, and II
I! ! The shape, structure, etc. of each part of the cargo sorter 9 may be modified or changed as appropriate. For example, the wedge-shaped groove 12 is provided at the corner portion 6b of the track bending portion.
The pair of plate-like members 10 and 11 that form this are not limited to thin plates, and may be thick block-shaped members.Furthermore, the wedge-shaped groove portion 12 may be formed in the form shown in FIG. It will be easily understood that various modifications are possible, including a shape such as
0.11, and its tip bent part 15.16,
A case is shown in which the wedge-shaped groove portion 12 is formed by contacting each other in a substantially square shape.

Further, the arrangement portion of the wedge-shaped groove portion 12 by the plate-like member 10.11 that characterizes the present invention is not limited to the bent portion in the coin sorting track directly below the coin input I+ in the above-mentioned embodiment, but is also provided in the coin storage portion. Of course, it may be provided at an appropriate bend in the coin trajectory.

〔Effect of the invention〕

As explained below, according to the non-IE operation prevention +)-) structure by the string-suspended coin according to the present invention, the track bending in the substrate constituting the coin track and the side plate that is openable and closable opposite the coin track is prevented. A wedge-shaped groove is formed when a pair of plate-like members are provided facing each other and protrude from the parts corresponding to the corners, and when the tips of these plate-like members are placed opposite to the substrate and the side plate. Therefore, despite the simple and inexpensive structure, the hanging string of a string-hanging coin can be easily and appropriately caught in the middle of the coin trajectory to hold it in place. Insert 4 coins into the coin storage side by M1,
Not only can this unauthorized operation be easily and appropriately prevented, but also? It is used for the return operation of the e position to release the above-mentioned suspended state of the hanging line, and the hanging line can be returned to the return track side together with the line-hanging coins, so there is no chance of coins getting jammed in the track like in the past. There are various excellent effects such as not having a 1 μm leak that causes a problem.
