Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a slot machine, a pachinko machine, and various other electronic game devices.

<Prior Art> This type of electronic game device incorporates an electronic control unit such as a microcomputer. However, among players, an increasing number of unauthorized users have caused an abnormal operation of an electronic control unit by generating an interfering radio wave by using a radio device or a piezoelectric element and sending the interfering radio wave into the game device. . In order to deal with this fraudulent activity, manufacturers have been devising measures such as incorporating a malfunction prevention device in the game console, but as this fraudulent activity becomes diversified and sophisticated year by year, new It is difficult to develop such a malfunction prevention device, and there are problems such as a plurality of internal circuits and an increase in machine cost.

Therefore, the applicant has recently proposed a method in which a metal foil such as an aluminum foil is attached to the inner surface of the box to shield the periphery of the electronic control unit (Japanese Utility Model Publication No. 58-80290). According to this method, the shield layer made of metal foil can prevent external signals from entering the box, and the abnormal operation of the electronic control section can be reliably prevented. Furthermore, this method is simple and inexpensive to implement. There is an advantage that you can.

<Problems to be solved by the invention> However, the front of the box is open, and a glass plate is provided in the front opening for the purpose of displaying symbols, signs, lighting, and see-through according to the game device. However, the same metal foil as that inside the box cannot be attached to this glass plate, and therefore fraudulent transmission of jamming radio waves from this glass plate portion is still performed. So, this invention, by configuring the glass plate with special glass,
It is an object of the present invention to solve the above-mentioned inconvenience and to provide an electronic game device in which transmission of an interfering radio wave to an electronic control unit is completely blocked.

<Means for Solving the Problems> This invention is an electronic game apparatus in which an electronic control unit is incorporated in a box having a shielded front opening, and a glass plate is provided in the front opening of the box. It is characterized in that the glass plate is made of conductive glass that has been subjected to an expression treatment with a transparent conductive film.

<Operation> According to the present invention, the box has a shielding effect, and in addition, the glass plate provided in the front opening of the box is made of the conductive glass surface-treated with the transparent conductive film. Since the board also has a shield function,
Radio waves from the outside are completely cut off, and abnormal operation due to jamming radio waves from the electronic control unit is reliably prevented.

<Embodiment> The drawings show an electronic game apparatus according to an embodiment of the present invention.

The electronic game device includes, for example, a plurality of rotating drums 1a to 1c.
Although the slot machine 1 having the above is shown, the present invention is not limited to this and is applied to various game devices having a pachinko machine and other electronic control units.

As is well known, the slot machine 1 is provided with an operation handle 2 for simultaneously rotating a plurality of rotary drums 1a to 1c on a side surface of a box 11, and a front surface of the box 11 includes the rotary drums 1a to 1c.
Push button 3 to stop 1c, vertical pattern on the outer circumference of the rotating drum,
There are provided a pattern display section 4 which is horizontally and diagonally arranged, an upper and lower guide display section 5 which displays guidance information related to game contents by lighting a lamp, and the like. An electronic control unit 6 for controlling is provided. A glass plate 7 is fitted in the opening of the box 1 in each of the pattern display section 4 and each guide display section 5, and each guide display section 5 has an illuminator 8 such as a blinking light bulb or a fluorescent lamp inside. Deployed and configured.

This invention is characterized in that a conductive glass 7a is applied to the glass plate 7. This conductive glass 7a has, for example, a third
As shown in the figure, a transparent conductive film 72 is formed by using a base glass plate 71 reinforced by coating a soda glass 711 with a silicon dioxide film 712 and subjecting a transparent conductive film 72 in which tin oxide is doped with fluorine to a surface treatment. Due to the shielding performance of
This prevents the interference of radio waves from the glass plate 7 and the emission of noise from the inside of the box.

In addition, it goes without saying that the panels other than the metal plate and the glass plate constituting the box 1 are formed with a shield layer on the inner surface of the panel, for example, by sticking a metal foil to completely shield the electronic control unit 6.

<Effects of the Invention> As described above, the present invention provides an electronic game apparatus in which an electronic control unit is incorporated in a box having a shielded front opening, and a glass plate is provided in the front opening of the box. Since the plate is made of conductive glass surface-treated with a transparent conductive film, the glass plate is also provided with a shielding function, and the shielding action of the box and glass plate completely blocks the intrusion of interfering radio waves from the outside.
As a result, the electronic control unit does not operate abnormally due to the interfering radio waves, and always operates accurately, thus achieving the remarkable effect of achieving the object of the invention.
