Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for preventing unauthorized operation of a coin sorting mechanism used in automatic ticket vending machines, commodity vending machines, coin timers, telephones, etc. that operate by accepting coins. be.

Structure of conventional examples and their problems In recent years, as product vending machines have become widespread, in order to make them operate illegally, coins are attached to strings, fishing lines, etc. and placed repeatedly to obtain products. Theft complaints are occurring frequently. In order to prevent unauthorized use of such coins with strings, fishing lines, etc. attached, structures shown in FIGS. 6 and 7 have been proposed. The conventional example will be explained below with reference to FIGS. 6 and 7.

In the figure, reference numeral 1 denotes a board that is slightly tilted upright inside the device, and its surface is subjected to non-magnetic treatment. Reference numeral 2 denotes a side plate opposite to the base plate 1, and a coin track member 3 is fixed to the base plate 1 between these members to form a coin track 4. This coin track 4 communicates with a coin input port (not shown) provided at the top of the device, and along this inclined track in the lower left corner of FIG. Further, a pseudo coin ejection track that is approximately parallel to the binding 14 is provided in the vicinity of these sorting path mechanisms, and the pseudo coins sorted by the sorting mechanism are The structure of the coins ejected from the ejecting track to the ejecting port is the same as that of the conventional coin sorting device, and a detailed explanation thereof will be omitted.

A coin accumulation track 6 communicates with the inclined track. This accumulation track 6 is a track in which a predetermined number of regular coins are accumulated in the diametrical direction of the coin. It consists of a bent vertical storage track 8. The coin track 4 is further branched into two tracks in the lateral and vertical directions below the vertical accumulation track 8 via a substantially triangular spacer 9 fixed to the substrate 1. is defined as a coin storage track 10, and the vertical track is defined as a return track 11. Note that the return track 11 communicates with the discharge port via the discharge track.

The coin storage track 10 is communicated with a safe (not shown) and is normally closed by a coin storage lever 13 extending through a groove 12 from the back side of the base plate 1.

On the other hand, the return track 11 is closed by a return lever 15 protruding into the track from a groove 14 drilled in the base plate 1, and the return lever 15 is inclined toward the storage track 10 side. Accordingly, regular coins are retained by these two levers 13, 15 and are stored in a predetermined number of coins in the storage track 6 in a line diametrically along the storage track 6.

The storage lever 13 is moved back from the track when the release of the product is completed or when a release signal is output, whereby a predetermined number of coins are stored.

Further, the return lever 15 moves back from the storage track and returns the items all at once by operating a switch provided on the front of the vending machine or by a sales end signal. Further, the inclined accumulation trajectory 6
The coin track member 16 constituting the lower part of the coin track member 16 is formed so that its width A is slightly smaller than the thickness B of the coin.
Its tip is bent into a crank shape, corresponding to the configuration of The upper surface of this coin track member 16 serves as a coin rolling surface, so it is formed as a smooth surface. Further, this coin track member 16 forms the same surface as the upper track member 3, and the support plate 1
It is fixed to the side plate 2 via the coin storage lever 7 with screws 18, and its lower end extends close to above the coin storage lever 13. Therefore, the storage track 6 includes the track member 16, the substrate 1, and the side plate 2 below the inclined storage track 6.
Gaps C and D are formed between them, respectively. In addition,
When the inclination angle of the track member 16 is α, its lower end 16
a and the height F to the lower edge E of the support plate 17, F
) d (d is the diameter of the coin), F X Cot a 〉d
The dimensions and shape satisfy the following relationship.

In such a device, when a fraudster ties a regular coin 19 with a string, string, tenges, etc. 20 and inserts it into the device, the accumulation trajectory 5 is configured as a bent trajectory consisting of an inclined accumulation trajectory 6 and a vertical accumulation trajectory 8. Therefore, track member 3
It is inserted into the gap C or D from the lower edge or the lower edge E of the intervening plate 17. At this time, the fraudulent person tries to retrieve the coin 19 by pulling the string 20, but the coin 19 collides with the lower surface of the track section #'+6 and is prevented from being retrieved. If you pull the thread even harder, it will break.

However, at this time, the coin 19 moves to the left in the slot due to reaction and enters the vertical accumulation track \8, and the thread 20 gets caught in the joint between the support plate 17 and the track member 16 secured by the screw 18. , As a result, the support board 17. There was a drawback that the thread 20 remained on the track member 3, making it impossible to move the coins smoothly thereafter.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a device for preventing unauthorized operation of a coin selection mechanism, which eliminates the above-mentioned conventional drawbacks and reliably guides coins even after the thread thread is operated by cutting the thread.

Structure of the Invention In order to achieve the above-mentioned object, the present invention includes a pair of plates provided with an input port at the top and installed vertically inside the device, and a sloped plate located between the pair of plates and communicating with the input port. A track surface member forming a coin trajectory, a passage wall forming a vertical coin track continuous with the inclined lower end of the track surface member and bending in communication with the coin track in a substantially perpendicular direction, and the track surface member and the passage wall. A cutout part with a size 74% smaller than the outer diameter of the coin is formed in the bending communication part, and a string is attached to the cutout part and is operated by the string when the coin passes through. A switch, a pair of cutting blades and a twister that are moved by a drive device operated by the switch to cut the string attached to the coin, and a pair of cutting blades that cut the string to prevent unauthorized manipulation. .

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

In the figure, 3o is a coin sorting mechanism that is installed at a slight angle inside a device such as a vending machine.

In this coin sorting device 30, a pair of plates 31 and 32 are arranged with an interval slightly larger than the thickness (2) of the coin receiving plate. One side of this pair of plates 31 and 32 (the first
A coin slot 33 is provided on the upper surface (shown on the left side of the figure) for restricting the passage of coins larger than a predetermined size into the space. One plate 31 at the bottom of the coin slot 33 is provided with a coin drop gutter 34 which is bent into a cross-section with an open upper end toward the exit of the coin slot 33. Further, a track surface member 35 is fixed to the lower part of the coin drop gutter 34 on the side surface of the plate 31 so as to be inclined downward to the right. At this time, there is a gap between the other plate 32 and the raceway surface member 36.

Therefore, the coins that have fallen through the coin drop gutter 34 from the input port 33 are transferred to the pair of plates 31, 32 and the track surface member 35.
The plate 31 runs on the inclined coin track 36 formed by the
While leaning on it, it fell due to its own weight.

Incidentally, along this inclined coin track 36, conventionally known screening mechanisms such as outer diameter, weight, material, etc. are appropriately arranged.

Furthermore, a pair of passage walls 38139t forming a vertical coin track 37 with open upper and lower ends are attached to one of the plates 31, extending in the vertical direction, at the tip, that is, the lowermost end, of the track surface member 36. A bent passage portion 40 is formed where the inclined coin track 36 and the vertical coin track 37 are bent and communicated with each other. And vertical coin track 37
An opening 41 is provided at the lower end of the coin, from which a stone /<-42 that projects into the vertical coin track 37 in a normal state is disposed. Therefore, a coin that has fallen through the vertical coin track 37 is stopped by the stopper 42.

Note that the vertical track 37 communicates with a safe (not shown) via this stone/<-42. Further, the bending passage portion 4 which is the lower end of the raceway surface member 36 and the upper end of the passage wall 38
A notch 43 is formed at the armpit position of o. That is, the lower end of the raceway surface member 35 is formed into a ground inclined surface 44 whose side edge on the free end side is shorter than the side edge of the plate 31, while the passage wall 3
A notch 43 is formed by opening the upper end of 8. 'Of course, the opening size of this notch 43 is made smaller than the outer diameter of the coin to prevent it from falling out of the opening. Reference numeral 44 denotes a microswitch attached to the outer wall of the plate 32 near the bending passage section 4o, and an operating lever 45 of this switch 44
The distal end thereof protrudes into the notch 43 from the hole 46 formed in the plate 32. The operating lever 45 is held at the bottom dead center by the lower end of the hole 46. 47 and 48 are a pair of cutting blades, one cutting blade 47 is attached to a string 49 (on the coin),
This string 49 is fixed to the plate 31 below the raceway surface member 36 and close to the notch 43 so as to come into contact with the string 49 when the operating lever 45 of the switch 44 is moved to the bottom dead center. are doing. This cutting blade 47 is bent into an oval shape, and the blade 47' is inserted into the plate 3 through a 5° hole formed in the plate 31.
1. The vertical side 47'' that protrudes between 32 and 32 is fixed to the plate 31 by caulking or the like.The other cutting blade 48 is rotatably attached to the plate 32 on the opposite side of the plate 31. It is being

That is, a hole 61 is formed in the plate 32, and this hole 51 is formed opposite to the hole 5o of the plate 31. Then, a lug 52 protruding outward from the lower end of this hole 61 is attached to the plate 3.
A cutting blade 4 is provided so as to protrude from the lug 52 and retract from the mI hole 51 through the hole 50'1 so as to intersect with the cutting blade 47.
8 is rotatably attached with a screw 155. At this time, the pair of cutting blades 47° and 48 provide the same effect as scissors. This is a drive device consisting of a solenoid that operates when the operating lever 46 reaches the bottom dead center, and moves the cutting blade 48 to a position where it overcomes the force of the spring 63 and intersects with the other cutting blade 47. 0 Also, the cutting blade 48 and the bottle 56
In the installation, the cutting blade 48 is installed by the pressure force of the coil spring 56, and the pin 65 presses the other side of the coil spring 66.

In such cases, a coin with a string 49 attached)
When a coin is inserted from the input port 33, the coin passes through the selection path mechanism on the inclined track, descends to the vertical track 37 via the bending passage section 40, and is stopped by the stopper 42. Here, even if the string 49 is slackened while the coin (E) is locked by the stopper 42, the switch 4
4 is never activated. On the other hand, when the stopper 42 retreats in response to the coin collection signal, the coin with the string is stored to its full thickness due to its own weight. However, the unauthorized operator pulls up the string 49 to prevent the coin from being stored. .

This operation naturally applies tension to the string, and this tension operates the switch 44. At this time, the string 49 is positioned in the gap between the plate 32 and the raceway surface member 35. That is, the string 49 is guided along the locus of the coin (e) from the input port 33 to the vertical coin trajectory via the inclined coin trajectory. It is matched. Therefore, when the string 49 is pulled up, the lower end of the coin drop gutter 34 and the operating lever 45 are in a straight line state, and force is applied to both points. However, since the lower end of the coin drop gutter 34 is fixed, the operating lever 45 is rotated counterclockwise as shown in FIG. 4, and the switch 44 is activated. The operation of this switch 44 causes the drive device 54 to operate and rotate the cutting blade 48. At this time, since the string 49 is located between the cutting blades 47 and 48, the cutting blades 47 and 48 intersect and cut the string 49.

As a result, when the string 49 is pulled from the input port 33, the string 49 can be removed smoothly from the raceway surface member 36.
There is no possibility of malfunction due to interference.

Furthermore, when a stringed coin ( ) is locked in the stopper 42 , when the string 49 is pulled to remove the coin ( coin ), the string 49 is placed on the operating lever 46 of the switch 44 at the notch 43 . Therefore, force acts on nine straight points between the lower end of the coin drop gutter 34 and the operating lever 45. Therefore, as described above, the actuating lever 46 is rotated counterclockwise, and the switch 44 is rotated counterclockwise.
is activated. After that, the drive device 54 is operated by this switch 44 to rotate the cutting blade 48 so that the string 4
Cut 9.

When the string 49 is cut, the operating lever 45 returns to its original state and the switch 44 is turned off. As a result, the drive device 54 also stops its operation, and the cutting blade 48 returns to its original state by the force of the spring 63.

In addition, if the string 49 is hard like steel, the cutting edge 4
7.48, but the cutting blade 48 overcomes the coil spring 56 and moves away from the cutting blade 47, and is sandwiched between the cutting blades 47 and 48. Therefore switch 4
Since the switch 44 is activated for a certain period of time, an alarm is issued or the operation of the vending machine is stopped to prevent unauthorized use.

Effects of the Invention As is clear from the above-mentioned embodiments, the present invention allows a coin with a string to be used for convenience, and when an unauthorized user pulls the string to apply tension, the string moves the coin.

The operation of this switch causes the cutting blade to move and act as scissors to cut the string, so that the string is reliably removed from the raceway member. Therefore, since no string remains on the track surface member in the receiving hole for the next coin, the coins can be guided smoothly and malfunctions such as selection errors can be prevented.
