Description

[Detailed description of the invention] The present invention is a device for preventing unauthorized use of a coin sorting device installed in a coin slot of a vending machine, a game machine, etc., and in particular, prevents unauthorized use by checking for unauthorized use with a wire. This is about a wire checker.

Publication No. 55-21191 and patent application No. 54-65356
As stated in the specification etc., a coin detection switch is provided at the bottom exit of the coin chute,
A coin sorting device is known in the art in which an operating arm of this switch projects into a coin chute passage, and a coin passing through the lower end of the switch rotates the switch operating arm to actuate a coin detecting switch.

In recent years, with the increase in the use of vending machines, game machines, etc., various types of unauthorized use that are unimaginable have occurred, and it is difficult to predict the occurrence of these unauthorized uses or to identify unauthorized uses that have actually occurred. Countermeasures have been taken in view of the act, and modern coin sorting devices have been improved to almost completely prevent possible fraudulent use.

However, as a very recent case of fraudulent use, a wire is inserted into the coin slot or other part of the coin chute to activate the operating arm of the switch installed at the bottom exit of the coin chute, allowing the machine to be used without coins being inserted into the vending machine. The act of activating game consoles, etc. has occurred and has become a problem.

The object of the present invention is to provide a device that prevents unauthorized use of such wires.

Hereinafter, the present invention will be explained with reference to the drawings.

In Figures 1 and 2, 1 is a coin chute through which sorted regular coins fall and pass;
2 and 3 are two mutually spaced chute side plates that define the coin chute passage 4, 5 is a coin detection micro switch attached to the chute side plate and provided for the lower end outlet 6 of the coin chute 1, and 7 is the coin detection micro switch. With the switch actuation arm, coins that constantly protrude into the coin chute path 4 through the slot 8 provided in the chute side plate, pass through the lower end outlet 6, and fall into the coin container (not shown) below, are activated by the switch actuation arm. By engaging with and pushing down the pivot pin 9
It is configured to rotate around the chute and move backward along the chute passage 4, allowing the coin to pass through the lower end outlet 6, and at the same time actuating the micro switch 5 to generate a signal for inserting a regular coin.

Reference numeral 10 denotes a line lifting prevention lever whose upper end is pivotally connected by a pin 12 to a support bracket 11 protruding from the chute side plate. It is energized by a weight part 15 so as to always protrude into the coin chute passage 4 at a position above the operating arm 7, thereby preventing unauthorized operation of the microswitch 5 due to a coin hanging on the thread.

Reference numeral 16 denotes a wire checker, which is pivotally connected to the chute side plate 3 by a pin 19 inserted into a pin hole 18 provided at the upper end, and moves the chute side plate from the switch operating arm rotation blocking position shown by the solid line to the retracted position shown by the phantom line. It is attached so that it can rotate along 3.

The lower end of the wire checker 16 is bent into a U-shape to provide a switch operating arm rotation blocking piece 20, and the lower end 21 of the main body of the wire checker 16 and the blocking piece 2 are provided.
0 to sandwich the lower end of the coin chute 1 from both sides, thereby correctly guiding the above-mentioned rotation of the wire checker 16.

The switch actuating arm rotation blocking piece 20 extends across the slot 8 and has an inclined engagement portion 22 extending across the rotation path of the switch actuating arm 7. The inclined engagement part 22 is positioned below the switch operating arm 7 that projects into the chute passage 4, and the inclined direction of the inclined engagement part 22 is tilted in the opposite direction to the inclined direction of the inclined surface 17 of the lifting blocking piece 13. The switch actuating arm 7 or the switch actuating arm rotation blocking piece 20 is fixed with a wire or the like.
Even when the wire checker 16 is pushed down, the tilt of the inclined engagement portion 22 acts to maintain the wire checker 16 in the switch operating arm rotation blocking position.

Inclined engagement portion 2 of switch operating arm rotation blocking piece 20
2 and a protruding arm 24 having a backward inclined engagement surface 23 is provided on the wire checker 16 at a position above the switch operating arm 7.
In the switch operating arm rotation blocking position, the protruding arm 24 is bent and protruded from the wire checker 16 body so that the retracting inclined engagement surface 23 is located in the coin chute passage 4, and the retracting inclined engaging surface in the upper position The engaging surface 2 is spaced so that a coin can simultaneously engage both the engaging surface 23 and the switch actuating arm 7 in the lower position.
3 is provided above and spaced apart from the switch operating arm 7.

To explain the operation of the device configured as described above, when a properly inserted coin falls down the coin chute path 4, it first hits the lifting prevention piece 13 and a downward force acts on its sloped surface 17, which causes the coin to be tilted. Side 1
The line hanging prevention lever 10 is rotated around the pin 12 by the horizontal component force acting on the blocking piece 1.
3 is retreated to the outside of the chute passage 4. As a result, the coin falls further downward in the coin chute passage 4 without being blocked by the blocking piece 13, and at that downward position, the coin is engaged in a backward inclined engagement on the protruding arm 24 protruding into the coin chute passage 4. The wire checker 16 is rotated around its pivot pin 19 by the horizontal force acting on the inclined engagement surface 23. As a result, the inclined engagement surface 23 and the operating arm rotation blocking piece 20 at the lower end retreat to the outside of the coin chute passage 4. This state continues while the coin is engaged with the inclined engagement surface 23, and the switch actuating arm 7 is spaced below the inclined engagement surface 23 by a distance shorter than the diameter of the coin. Blocking piece 2
While the coin is in the retracted position, the coin pushes down the switch actuating arm 7, and the switch actuating arm 7 rotates and retreats out of the chute passage 4, causing the coin to pass through the lower end outlet 6 of the coin chute 1. At the same time as it falls, the micro switch 5 is activated.

However, an unauthorized user inserts a wire from a coin slot (not shown) and presses down the retreating inclined engagement surface 23 of the protruding arm 24 with the bent portion of the tip of the wire. When retracted outward, at the same time the switch actuating arm rotation blocking piece 20
Although the switch operating arm 7 retreats out of the rotation path,
This retraction is instantaneous and not continuous;
As soon as the bent portion of the wire tip and the inclined engagement surface 23 are disengaged, the thread hanging prevention lever and the switch actuation arm rotation blocking piece 20 protrude into the rotation path of the switch actuation arm, preventing the switch actuation arm from rotating. Return to blocking position. Therefore, after the wire tip bent portion disengages from the inclined engagement surface 23, the switch actuating arm 7
Even if it engages with and pushes down, the switch operating arm 7
is engaged with the inclined engagement portion of the blocking piece 20 and is prevented from rotating, and the switch is not operated.

In the illustrated example, the above-mentioned wire checker 16
Thread hanging prevention lever 1 prevents the arm from rotating.
0, the wire checker 16 is provided with a wire checker rotation preventing engaging portion 25.
and a rotation position regulating engagement portion 26. The wire checker rotation prevention engaging portion 25 constantly engages with the line hanging prevention lever 10 to prevent rotation of the wire checker 16, thereby moving the protruding arm 24 and the lower end switch operating arm rotation prevention piece 20 to the chute passage. 4 and within the switch actuating arm rotation path, and the coin engages with the engaging surface 23 of the protruding arm 24 only when the lever 10 is rotated to the retracted position by the coin. As a result, the wire checker 16 is swung and its engaging portion 26 engages with the lever 10, and in this state, the blocking piece 20 retreats out of the switch operating arm rotation path, allowing the switch operating arm 7 to rotate. As a result, the switch 5 is actuated at the same time as the coin passes through the lower end outlet 6.

With this configuration, when a properly inserted coin falls down the coin chute passage 4, the coin first hits the lifting prevention piece 13 and falls on its inclined surface 17.
A downward force is applied to the slanted surface 17, and the line hanging prevention lever 10 is rotated around the pin 12 by the horizontal force acting on the inclined surface 17, and the blocking piece 13 is retreated to the outside of the coin chute passage 4. . By rotating this thread hanging prevention lever 10, the wire checker 1
The engagement portion 25 of No. 6 and the thread hanging prevention lever 10 are disengaged.

Next, while the coin is engaged with the blocking piece 13 in the retracted position, it hits the inclined engagement surface 23 for retracting the wire checker, and a downward force is applied to the engagement surface 23, and the coin also moves in the horizontal direction. The wire checker 16 is rotated around the pin 19 by the component force of
As a result, the switch actuating arm rotation blocking piece 20 also retreats out of the rotation path of the switch actuating arm 7, and this state continues while the coin is engaged with the engaging surface 23, and the switch actuating arm 7 is engaged with the inclined engagement. By being spaced below the mating surface 23 by a distance shorter than the diameter of the coin, the coin pushes down the switch actuating arm 7 while the blocking piece 20 is in the retracted position, and the switch actuating arm 7 rotates. As a result, the coin passes through the lower end outlet 6 of the coin chute 1 and falls, at the same time actuating the micro switch 5.

However, the unauthorized user inserts the wire into the coin slot (not shown) and presses down the lifting prevention piece 13 of the thread suspension prevention lever 10 with the bent portion at the tip of the wire, and retreats the prevention piece 13 out of the chute passage 4. At the same time, the thread hanging prevention lever 10 and the wire checker 16 are disengaged from each other at the engaging portion 25. However, the retreat of the blocking piece 13 is instantaneous and is not performed continuously, and as soon as the bent portion of the wire tip and the blocking piece 13 are disengaged, the line hanging prevention lever 10 returns to its original position. As a result, the thread hanging prevention lever 10 and the wire checker 16 are engaged again at the engaging portion 25, so that even if the wire next engages with the wire checker backward inclined engagement surface 23 and pushes it down, the wire Checker car 1
6 is not rotated. Therefore, the switch actuating arm rotation blocking piece 20 is located within the rotation path of the switch actuating arm 7, and even if the switch actuating arm is pushed down, the switch actuating arm 7 will not engage with the inclined engagement portion 22 of the blocking piece 20. The switch is prevented from rotating and the switch is not activated.

According to the present invention, unauthorized use of the wire can be reliably prevented as described above.
