Description

[Detailed Description of the Invention] (Industrial field of application) The coin sorting device according to the present invention is for sorting a single coin, that is, one kind of genuine coin, which is used in various vending machines and cam machines. The present invention relates to a coin sorting device, and particularly to an electronic single coin sorting device (hereinafter, simply referred to as "coin sorting device") for discriminating the material and size of a coin by a sensor coil.

(Prior Art) As a coin sorting apparatus up to now, for example, Jikken Sho 5
The thing described in 9-29250 is known. This coin sorting device is a means for sorting the size and material peculiar to coins, a receiving chute for accepting the coins after the sorting when the coins are genuine coins, and a receiving chute when it is a pseudo coin. It has a return chute for retreating and a gate means for distributing the input coins to a receiving chute or a returning chute, which are incorporated in a single casing.

Further, as a means for selecting the size and material peculiar to a coin up to now, for example, the one described in Japanese Utility Model Publication No. 58-50461 is known. This means oscillates an oscillating circuit consisting of a sensor coil having an inductance L and a capacitance C, and utilizes an alternating magnetic field in which a current flowing in the oscillating circuit induces in the sensor coil.
That is, when a metal, that is, a coin is put in the alternating magnetic field, an "eddy current" that causes an electrical loss flows in the metal, and the impedance of the sensor coil changes. Therefore, this change is used to judge the authenticity of coins.

(Problems to be Solved by the Invention) The conventional coin sorting device as described above needs to be manufactured according to the coin to be sorted. For example, when sorting 5 cent coins, a coin sorting device dedicated to 5 cent coins, and when sorting 1 dollar coins, a coin sorting device dedicated to 1 dollar coins must be manufactured. There wasn't.

On the other hand, in order to make one coin sorting device compatible with two or more different coins, the sorting means has been adjusted. As the adjusting means, for example, by changing the inductance L of the sensor coil, a 5 cent coin and 1
Some are trying to accommodate both dollar coins. However, it is not always easy to make such adjustments, and it is extremely difficult to adjust the coin sorting device actually incorporated in the vending machine or the like.

By the way, at present, various kinds of coins and tokens (nominal coins) are used in various countries around the world, and the demand for a coin sorting device for sorting these coins and the like is increasing. However, manufacturing a coin sorting device corresponding to these coins or the like exclusively for the coins or adjusting the coins according to the coins or the like causes complication of the manufacturing line and production. There is a problem of making the cost expensive.

Further, it is also known that many kinds of coins, for example, a five-cent coin and a one-dollar coin are simultaneously selected by one coin sorting device. This is, for example,
It is disclosed in Japanese Patent Publication No. 395. However, such a coin sorting device generally has a problem that the structure is still complicated and expensive.

In order to solve the above problems, there is a coin selection device proposed, for example, in Japanese Utility Model Publication No. 62-13175. This is because when a coin to be sorted is changed, a unique part for sorting the coin, that is, a partition plate provided in the coin passage and a sorting means are detachably configured and are exchanged. Only by doing so, the coin sorter suitable for the change can be modified. However, since the attachment of this unique portion is performed by a screw, a special tool such as a screwdriver is required for its removal and attachment, and it is inconvenient because it cannot be easily replaced.

(Problems to be Solved by the Invention) Problems to be solved by the present invention are as follows. That is, it is an object of the present invention to provide a low-priced coin sorting device that solves structural or adjustment problems of the coin sorting device and is capable of sorting each of various types of coins with high accuracy. More specifically, it is to provide a coin sorting device in which a specific part for sorting coins can be easily attached and detached and replaced without using a special tool.

(Means for Solving the Problem) A coin sorting device according to the present invention solves the above-mentioned problems and is as follows.

That is, a unique component part in which means for electronically selecting the size and material peculiar to the input coin is housed and the unique component part are separately configured, and a common part for detachably receiving the unique component part is provided. In an electronic single coin sorter consisting of constituent parts, the common constituent part comprising a coin receiving chute, a coin returning chute and a gate means, the outer side walls provided on both sides of the specific constituent part are engaged with each other. Protrusions are provided so as to protrude, and side plates corresponding to the both outer side walls are provided on both side faces of the common component, respectively, and both side plates are provided with retaining holes for retaining the engaging protrusions. The both hooking holes are elastically openable so that the hooking protrusions are configured to be disengaged from the hooking holes. That.

(Operation) The coin sorting device according to the present invention is used as follows.

That is, the common constituent part that is the main body of the coin sorting device,
For example, it can be used as a common part for receiving coins having a relatively small diameter such as a 5 cent coin to coins having a relatively large diameter such as a dollar coin. Therefore, when a coin sorting device that sorts new coins of different types is required, a new coin sorting device that is different by simply replacing the existing unique component with the unique component corresponding to the coin to be sorted. Is completed.
At this time, the engaging projection provided on the unique component engages with the retaining hole provided on the common component, and the unique component is received and held by the common component.

When removing this unique component, follow the procedure below. That is, since the hooking hole is elastically openable, the hooking hole can be widened, and thereby the hooking protrusion can be disengaged.
Then, when the engaging protrusion is released, the retaining hole returns to its original state by its elastic force.

On the other hand, conversely, when fitting the unique component into the common component, the following procedure is performed. That is, it is possible to insert the engaging projection by inserting the engaging projection while expanding the engaging hole and holding the engaging projection so as not to come off due to the elastic return of the engaging hole.

As mentioned above, since the unique component parts corresponding to the coins to be selected can be removed and replaced without using a special tool,
It is possible to easily and quickly change to a coin sorting device that supports different types of coins. Further, since the common component can be used for coins of different types, the manufacturing cost can be kept low.
