Abstract

PURPOSE:To give a value judging data other than the size and the weight inside a coin, so as to prevent to forge by an outsider, as well as to make the judgement of the coin easier and securer, by including a built-in IC in a disk-form substance in appearance. CONSTITUTION:In a disk-form substance in appearance, an IC 12 is built in. Therefore, since a coin is made into an IC furnishing a cell to generate a power by radiating the light to a disk-form substance in appearance and an electric circuit to output a predefined data to the outside through a luminous element, not only the judgement by the scope of the size and the weight used in the conventional coin judgement method can be carried out but also the confirmation of the coincidence with the coin by the communication data can be carried out additionally. Consequently, a forged coin of the same size and weight can be detected easily, and an unjust use of the coin can be prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides a coin-shaped IC that outputs predefined information using a light emitting element by applying a light beam from the outside.
It is related to.

[Conventional technology]

Figure 6 shows an example of the appearance of coins used in conventional amusement arcades. FIG. 7 is a front view of the gaming machine, and FIG. 8 is an explanatory diagram of the internal structure regarding coin determination of the gaming machine.

Generally, the size and weight of the coin 1 are determined to distinguish the coin. The gaming machine 2 is equipped with a coin slot 3, a size determining device 4, and a weight determining device 5 to distinguish coins 1, and when 10 coins are distinguished, a switch 6 is activated and the game is played a specified number of times. Go, coin 1
If the coin is judged to be outside the regulations based on its size or weight, it will be placed in the return box 7.
The game machine does not operate because the switch 6 does not function. Next, the operation will be explained. When a coin 1 is inserted into the slot 3 of the gaming machine 2, coins larger than the specified size cannot be inserted into the slot 3, so that coins 1 are restricted. The coin 1 that can be inserted from the input slot 3 passes through the size determination device 3, and if it is not the specified size, it is determined that it is not the coin 1 and is sent to the return slot 5. If the size is the specified size, the next coin is sent to the return slot 5. The weight is then sent to the determining device 4 and the weight is determined. Here too, if the weight is other than the specified weight, it will be sent to the return port 5, and if it is the specified weight, it will be judged as coin 1 and the switch 6 will be activated to operate the gaming machine as specified, and coin 1 will be sent to the collection box. Enter 7.

[Problem to be solved by the invention]

Conventional coins were structured as described above, so the only standards for judging coins were the size and weight, and in gaming machines that operate based on the value of the coin, the coin judging device strictly determines the size and weight. There is a problem that the determination device becomes complicated.b1Also, since coins are subject to wear and deformation due to use, the regulation of dimension 11 requires a certain range. Because it is easy to measure the dimensions and weight of a single coin, it is possible to produce counterfeit coins of the same dimensions and weight, and there is a problem in that counterfeit coins of the same dimensions and weight cannot be determined to be fakes.

This invention was made to solve the above-mentioned problems, and by defining value judgment information other than dimensions and weight inside the coin, it makes it easy and reliable to judge the coin. The purpose is to obtain coins that cannot be easily counterfeited by anyone.

[Means to solve the problem]

The coin type ■0 according to the present invention has coin value judgment information defined on an object having a disk-like outer shape, and a photovoltaic cell that drives the IO and OIa that outputs this information to a light emitting element by power supply is arranged. It is.

[Effect]

The coin-shaped tool o in this invention has a built-in 10
Since the coin value judgment information defined in 1 can be obtained without contact with the coin through optical transmission, it is possible to make the coin judgment more accurate by confirming the coin value judgment in addition to the conventional size and weight judgment. I can do it. In addition, since the internal information converted to IO cannot be easily decoded by a third party, it is possible to omit or simplify the conventional determination of dimensions and weight, and the coin-shaped IO makes it compact. It offers features such as being not too bulky and strong.

When the coin type I09 is inserted into the slot 3 of the coin type I09, first, coins larger than the specified size cannot be inserted into the slot 3. The coin type I09 that can be inserted from the input port 3 passes through the size determining device 3t, and if the size is not the specified size, it is determined that it is not a coin type I09 and is sent to the return port 5, even if the size is the specified size. Then, it is sent to the weight determining device 4 and its weight is determined. Here too, if the weight is other than the specified weight, it is sent to the return port 5, and if it is the specified weight, it is sent to the communication unit 20 with the coin type IO.

The internal information receiving section n receives this as an optical pulse, and the internal information decoding section converts it into a serial data electrical signal of OIOIOOIIB, and then the data set in advance as comparison data 01010011B in the internal information determining section 26 matches. Then, it is determined that the coin is in the specified coin shape 10, and the switch 6 is activated to start the specified operation of the gaming machine. The coin-shaped IO is then stored in the collection box 7. If it is determined that the coin is not a specified coin type IO, it is sent to the return port 5 and the switch 6 does not function, so that the game machine does not operate.

However, as shown in FIG. 5, a light receiving element and a light receiving element receiving part are provided, and the transmitted and received data is controlled by a single chip. If microcomputer processing is performed by the microcomputer 29, it is possible to process a large amount of information, and it goes without saying that the coin value can be changed and set from the outside with the same appearance. In the figure, 18 indicates a light emitting element driving section, and 19 indicates a light emitting element section. In addition, although the above embodiment shows the case of a coin for a game machine, it can also be applied to applications such as using it as an electronic key for a door, etc., and opening the key by confirming data matching.

In the above embodiment, the data in the information ROM section 16 is shown as having a length of 8 bits, but the data length may be less than or equal to 8 bits, depending on the number of combinations, and the comparison data of the information ROM section 16 and the internal information determination section Ibara may be made to match. You can set it freely if you want.

In addition, in the above example, the wavelength of light given to the photovoltaic cell and the wavelength emitted by the light-emitting element used for data transmission are in the visible light range for the photovoltaic cell and in the infrared range for the light-emitting element, but each element is set to a wavelength that is efficient. The same effect can be obtained even if the buttons are changed so that they do not overlap, and if the buttons use lasers with a wavelength close to each other, the optical filter for the photovoltaic light emitting section and the optical filter 24 for the internal information receiving section become unnecessary.

〔Effect of the invention〕

As described above, according to the present invention, a coin is an object having a disc-shaped outer shape, which is equipped with a battery that can generate electricity using light rays, and an electric circuit that outputs predefined information to the outside through a light emitting element by supplying power. Since it is an IC, in addition to the conventional coin identification method based on the size and weight range, it is possible to confirm the match based on communication data with the coin, making it easier to identify fake coins of the same size and weight. death,
Unauthorized use can be prevented.

In addition, instead of elements that can be easily measured such as conventional coin dimensions and weight, the coin contains information that cannot be easily known to a third party, so it is possible to obtain a coin that cannot be easily produced as a counterfeit coin. In addition, it is possible to omit or simplify the semi-determination of the coin dimensions and weight in the equipment that functions with the coin, which has the effect of reducing costs without reducing reliability. Coin-shaped ICs have the advantage of being structurally small, not bulky, and strong.
