Description

  The present invention relates to an IC coin, and more particularly to an IC coin formed by insert molding an IC tag or an IC film having an antenna coil and an IC chip electrically connected to the antenna coil.

  As this type of IC coin, for example, a cycle coin used in a game hall (pachinko store, game center, etc.) is already known. Normally, when a player enters a game hall and sits on a chair of a desired game machine (for example, a pachinko machine), the player first puts cash into a ball lending machine adjacent to the game machine to make a game medium (pachinko ball). I had to borrow. This ball lending machine does not accept high-value banknotes (5,000 yen bills, 10,000 yen bills), so if a player has only high-value banknotes, he / she will use a money-changing machine installed in the amusement hall in advance. Had to be exchanged for small bills (thousand yen bills). Also, if the player wishes to continue the game even when the exchanged small amount banknote is used up, the player has to exchange the large amount bill with the small amount bill again with the money changer. Therefore, depending on the player, a plurality of exchange operations may be required, so the exchange operation has been troublesome for the player. In addition, the time during which the player exchanges money has been a problem for the game arcade because the operating rate of the game machine is reduced. In order to solve this problem, a ball lending machine capable of inserting high-priced banknotes has been developed, but from the viewpoint of cost reduction, the fishing change was returned as cycle coins without being returned in banknotes. For example, if a player puts 10,000 yen into a ball lending machine and pays out after borrowing 7,000 yen worth of game media, one ball lending machine is 3,000 yen per player. I was refunding one IC coin. Then, the player is to convert the cycle coins into banknotes with a payment machine installed in the amusement hall.

As prior art document information related to the invention of this application, for example, Patent Document 1 is known.

  The above-described cycle coin has been manufactured by insert-molding an IC tag having an antenna coil and an IC chip electrically connected to the antenna coil with a resin material. Therefore, when a player has a cycle coin, if the weight is insufficient, the cycle coin is used as a substitute for a banknote, so that the value as a coin is reduced. It was. In order to solve this problem, when inserting an IC tag, a metal piece or the like is also inserted to meet the required feeling of weight. However, if a metal piece is inserted into the IC coin, the transmission and reception of the antenna coil may be hindered, causing a trouble in the settlement machine.

  An object of the present invention is to provide an IC coin that can secure a desired feeling of weight without obstructing transmission / reception of an antenna coil.

The present invention is for achieving the above object, and is configured as follows.
According to the first aspect of the present invention, there is provided a molded product obtained by insert molding an IC tag or an IC film having an antenna coil and an IC chip electrically connected to the antenna coil with a high specific gravity material, and further a resin material. IC coin formed by insert molding.
As the high specific gravity material, a nylon resin material mixed with metal powder is used, so that a desired feeling of weight can be secured without hindering transmission and reception of the antenna coil.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Example 1
First, Example 1 will be described with reference to FIG. FIG. 1 is an overall perspective view of the IC coin 1, and a part of the IC coin 1 is cut away. The IC coin 1 is formed by insert molding an IC tag 20 with a high specific gravity material 30 and further insert molding with a resin material 40 to integrate the IC tag 20, the high specific gravity material 30 and the resin material 40. It is configured. Further, the shape has an appearance shape that is recognized as a coin and an appropriate weight feeling.

  The IC tag 20 is known and includes an antenna coil 21 and an IC chip 22 electrically connected to the antenna coil 21. The antenna coil 21 can transmit and receive a predetermined signal without contact with the settlement machine. Further, the IC chip 22 has storage means capable of storing monetary amount information (for example, thousand yen). When the IC chip 22 receives a predetermined signal from the settlement machine via the antenna coil 21, the antenna coil The money amount information stored via 21 is transmitted to the settlement machine. The IC tag 20 has a power supply configuration that supplies necessary power to the IC chip 22 by the electromotive force generated by the antenna coil 21.

  The IC tag 20 configured in this manner is placed in a first mold (not shown) having a disk-shaped cavity and injection molded (insert molding) with a high specific gravity material 30, and then cooled and cured to 1 The next molded product is manufactured. The high specific gravity material 30 is obtained by mixing a powder of a metal (for example, tungsten, iron, copper, etc.) with a nylon-based resin material (for example, nylon 6, nylon 66, nylon 12, etc.) 40. As an example, a resin material obtained by mixing 90% of tungsten with nylon 6 is used. The size and weight of the primary molded product thus manufactured excluding the IC tag 20 are, for example, an outer diameter of 25.6 mm, an inner diameter of 10.2 mm, a thickness of 1 mm, and a weight of 5. 2g. Moreover, since the powder of a general purpose metal is used, it can manufacture easily.

  In this way, the primary molded product is placed in a second mold (not shown) having a cavity corresponding to the outer shape of the desired coin and injection molded by the resin material 40 so as to cover the entire primary molded product ( Insert molding), and then cooling and hardening to produce the IC coin 1. The resin material 40 is the nylon-based resin material 40 described above. Thus, the IC coin 1 is manufactured by performing insert molding twice. As for the size and weight of the IC coin 1 manufactured in this way, for example, the outer diameter is 32 mm, the thickness is 2 mm, and the weight is 5.5 g.

  According to the above-described IC coin 1, since it is formed only by insert molding, the bonding step is unnecessary, and therefore the IC coin 1 can be manufactured with a simple configuration. Further, in the high specific gravity material 30, since the metal is in a powder form and the powders are not in contact with each other, the high specific gravity material 30 does not exhibit electrical characteristics of “1Ω · cm” or more. Thereby, transmission / reception of the antenna coil 21 is not hindered.

(Example 2)
Subsequently, Example 2 will be described with reference to FIG. FIG. 2 is an overall perspective view of the IC coin 11 and a part of the IC coin 11 is cut away. In comparison with the IC coin 1 described in the first embodiment, the IC coin 11 is obtained by replacing the IC tag 20 with a known IC film 50. Therefore, like the IC tag 20, the IC film 50 includes an antenna coil 51 and an IC chip 52 electrically connected to the antenna coil 51. In the following description, the same members as those in the first embodiment or members having the same action are denoted by the same reference numerals, and detailed description thereof is omitted.

  As is apparent from FIG. 2, the IC coin 11 is formed by insert-molding a molded product obtained by insert-molding the IC film 50 with the high specific gravity material 30 with the resin material 40. 30 and the resin material 40 are integrated. Therefore, the same effect as the IC coin 1 can be obtained from the IC coin 11.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In each embodiment, the case where the outer shape of the IC coins 1 and 11 is a disk shape has been described as an example. However, the present invention is not limited to this, and the outer shape of the IC coins 1 and 11 may be a triangular plate shape or a square plate shape.

FIG. 1 is an overall perspective view of an IC coin 1, and a part of the IC coin 1 is cut away (Example 1). FIG. 2 is an overall perspective view of the IC coin 11 and a part of the IC coin 11 is cut out (second embodiment).
