Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a return coin receiver used for returning coins in public telephones, vending machines, etc.

<Prior art> Generally, in public telephones, etc., the user can drop the returned coin into a return coin receiver and take it out from the takeout port. The coin return path from which the coins fall is a transparent cavity with no obstacles and is connected to the takeout port (Utility Model Publication No. 49-18080).

<Problems that the invention aims to solve> However, in conventional return coin receptacles, the coin return path that communicates with the ejection port is a clear cavity with a large space leading upward, making it difficult for fraudsters to commit fraud. The person attempting to recover the coins presses a resilient object like a balloon into the upper part of the coin return path from the outlet through the gap between the opening/closing plate and the outlet.
Balloons are used to block change that should be returned to other users, causing it to remain in the coin return path, and after the user leaves, the balloons are removed and the change cannot be stolen from the exit. There was a problem.

The present invention has been developed in view of the above circumstances, and its purpose is to provide a return coin receiver that prevents fraud from stealing change by pushing balloons deep into the return slot.

<Means for solving the problem> In order to solve this problem, in the return coin receptacle of the present invention, the coin return path leading to the return slot is
A downwardly sloping projecting piece is provided from the wall surface of the coin receiving section on the opposite side of the return opening/closing plate at the back and above the maximum rotational position of the opening/closing plate, and a downwardly inclined downward slope near this projecting piece is provided. and a protruding sharp piece is provided.

<Function> Even if the opening/closing plate is rotated to the back and the balloon is pushed into the back through the gap of the outlet, the protruding piece prevents the balloon from moving to the upper part of the back. Then, when the opening/closing plate is rotated, the balloon is strongly pinched between the opening/closing plate and the protruding piece, hits the sharp piece, and ruptures.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 is a perspective view showing the whole of an embodiment of the present invention, Fig. 2 is a vertical sectional view thereof, and Fig. 3 is a perspective view with some parts omitted to show its internal structure. , In the figure, 1 is the main body of the return coin receiver,
It can be attached to a predetermined location on devices such as telephones and vending machines.

A receptacle 2 at the upper end of the main body 1 is provided with a leak-shaped slope 2a for receiving returned coins that fall from the device main body (not shown).

An outlet 3 is opened in the front part of the main body 1, and an opening/closing plate 4 is provided in the outlet 3. The opening/closing plate 4 has an upper part that is pivotally supported on the main body 1 by a pin 4a or the like so that it can rotate toward the inner part of the main body 1, and a lower end that expands into the main body 1. The weight of the weight portion 4b or a spring (not shown) automatically returns it to the closed position shown by the solid line.

Note that 4c is an opening/closing plate for inserting a finger and pulling back the opening/closing plate 4 when the opening/closing plate 4 does not return due to its own weight or spring force from the chain line position where it has been tampered with with adhesive, adhesive, chewing gum, etc. This is an L-shaped finger hook piece attached to the front side of 4.

Below the outlet 3 of the main body 1, a return coin receiving part 5 in which dropped returned coins are collected is formed in a mortar shape.

Note that a protrusion 9 is provided on the side wall of the receiving portion 5 to prevent accumulated coins from sticking and becoming difficult to take out.
is formed.

On the inside of the side wall of the receiver main body above the maximum rotation position indicated by the chain line of the opening/closing plate 4, there are a protruding piece 6 for preventing insertion of foreign matter and a sharp piece 7 having a needle-like tip.
It is built on a downward slope.

As shown in FIG. 3, the protruding pieces 6 have a plate-like shape, and alternately pass from the left and right opposing side walls to the coin return path leading downward from the upper receptacle 2 inside the receptacle 1. They protrude downwardly, facing each other and protruding alternately to form a zigzag path for coin passage inside the receiver, allowing foreign objects such as paper and wire to be pushed through the outlet 3. making it extremely difficult. Furthermore, even if you push the opening/closing plate 4 and try to insert paper or wire from the outlet 3, if the opening/closing plate 4 rotates to the back of the main body 1, the weight part 4b of the opening/closing plate 4 and the receiver main body 1 will come into contact with each other. Since the gap between the protruding piece 6 and the protruding piece 6 becomes smaller, it becomes extremely difficult to push the protruding piece 6 in.

The sharp piece 7 is for bursting a balloon when it is inserted, and for this reason, like the protruding piece 6, the sharp piece 7 is located below the protruding piece 6 above the maximum rotation position of the opening/closing plate 4. It is located on the side. and,
The main body 1 is fixed to a housing 8 of the device such that the outlet 3 is located at the front.

<Effects of the invention> In this way, in the return coin receiver of the present invention, from the wall surface of the coin receiving part 1 at the back of the take-out port on the opposite side to the opening/closing plate, to the upper part of the back from the maximum rotational position of the opening/closing plate. Since it is constructed by providing a protruding piece 6 that slopes downward, and further providing a sharp piece 7 that slopes downward near the protruding piece 6, even if you try to push the balloon to the upper part of the back, the protruding piece 6 will prevent it from going further. progress is blocked.
Then, the sharp piece 7 pierces and ruptures. If the balloon is small or due to the way it is pushed,
Even if the sharp piece 7 does not stick and the balloon is stuck between it and the protruding piece 6, when the next user turns the opening/closing plate 4 to the back to take change, the balloon inside will be removed. Since it is strongly pressed against the protruding piece 6 by the opening/closing plate 4, it will come into contact with the sharp piece 7 and burst, making it impossible to steal change after the next user leaves.
