Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to medals for game machines used in various medal-type game machines.

BACKGROUND ART With the spread of medal-type game machines, malicious acts such as counterfeiting of medals and fraudulent use of medals from other stores are rapidly increasing. To deal with this, various methods have been tried to distinguish medals from other stores, such as carving unique patterns on the medal surface, or creating recesses in the medals and pouring paint into them to color them.
There were drawbacks such as the patterns being worn away and the paint peeling off due to the medals colliding with each other during the game.

Furthermore, even in the same store, if the types of medals differ depending on the type of game machine, the discrimination becomes even more complicated and takes time.

Therefore, a medal with a high magnetic permeability material inside the medal body made of a synthetic resin material was developed as Utility Model Application No. 55-10181, and a hole with a raised part was provided in the medal body, and a colored synthetic resin was inserted into the hole to prevent it from slipping out. A medal to prevent unauthorized use of a game machine with a color display made by injection hardening was proposed as Utility Model Application No. 59-40969, but these medals were based on the magnetic and electrical properties of highly permeable materials and the color display. Medals were simply identified by the color of the display.

Problems to be solved by this invention The purpose of this invention is to make it possible to accurately and quickly determine whether a medal is a genuine medal by utilizing the light-gathering properties of a convex lens, and to easily and reliably distinguish between different medals depending on the type of game machine. To provide a medal for a game machine that can be used to operate various devices of the game machine.

Means for Solving the Problems In order to achieve the above object, the medal for a game machine of the present invention has a configuration characterized in that a through hole is formed in the medal body and a convex lens is fitted in the through hole. have

Function: The color and shape of the convex lens distinguish medals from other stores and medals for other game machines, and the convex lens transmits light from the light source to the light-receiving element, which enables the coin ejector and coin counting device. Operate various devices such as devices.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

M is a medal for a game machine according to the present invention;
It is made of metal and has a roughly disc-shaped shape, and is used in various medal-type game machines.

1 in FIG. 1 is the main body of the medal M, in which a through hole 2 is formed in the center thereof, and a locking groove 3 for preventing slipping out is formed approximately in the center of the circumferential surface of the through hole 2 in the thickness direction. It is formed.

A convex lens 4 made of colored or colorless transparent plastic is fitted into the through hole 2, and the peripheral edge of the convex lens 4 is engaged with the locking groove 3.

In addition, as shown in FIGS. 2 to 4, the through holes 2 may be formed in various shapes such as circular or square, or may be formed in multiple shapes, and even in the case where there are multiple through holes 2, all of the through holes have convex lenses 4. The color or shape of the convex lens 4 is different for each game machine.

A light receiving element (not shown) is placed at a position where the light from the light source is concentrated by the convex lens 4 of the medal M.
By connecting the light receiving element to various devices in the game machine such as a coin ejecting device and a coin number detecting device, the electrical signals converted from optical signals in the light receiving element can be used to operate the various devices. It becomes possible to perform reading, etc.

Effects of the invention As described above, this invention allows medals to be distinguished from medals from other stores by predetermining the color and shape of the convex lenses attached to the medals, and by predetermining the color and shape of the lenses of other stores. To make it possible to very easily, accurately and quickly distinguish between medals used in various game machines in one's own store. For example, by making the convex lenses of the medals at your own store red and changing the shape depending on the type of game machine in your store, it is easy to distinguish them from other stores and the medals depending on the type of game machine in your store. Become. Furthermore, detection using a color sensor can also be performed, and if this is done,
The sensor itself has been simplified and can be easily sorted, and by embedding a convex lens, it does not wear away like a stamp or peel off like paint, so it can be used beautifully all the time.

In addition, since a convex lens is fitted into the through hole formed in the medal body, the light from the light source is refracted by the convex lens, concentrated at one point, and transmitted to the light receiving element. In addition, it is possible to convert optical signals into electrical signals using the light receiving element, and also reduces the tolerance of the positional relationship between the medal and the light receiving element to eliminate false detections caused by fake medals and ensure the reliable operation of various devices inside the aircraft. It becomes possible to do so.
