Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine such as a pachinko machine or a slot machine which is electrically controlled. In particular, it relates to a configuration for preventing an abnormal operation of the electric circuit.

[0002]

2. Description of the Related Art Pachinko machines such as pachinko machines include:
Many electric members are provided, and when energizing them, an electromagnetic wave is generated, and at the same time, a large amount of static electricity is generated as a metal piece such as a game ball moves. In the related art, the noise is mixed into the electric signal flowing from inside each member of the pachinko gaming machine to the inside of the gaming machine, which often causes malfunction or failure of the electrical member.

As a conventional noise countermeasure, for example, Japanese Unexamined Patent Application Publication No.
Japanese Patent No.-218095 discloses a configuration in which a conductive shield layer connected to a ground line is formed on a control board of a game machine to protect the control board for the game machine from electrostatic noise. However, this method is only a countermeasure against noise on the control board, and cannot eliminate electromagnetic waves and static electricity that intrude from the electric wiring and its joint. Japanese Patent Application Laid-Open No. Hei 7-144058 discloses a configuration in which substantially the entire back mechanism panel of a gaming machine is formed of conductive plastic or a configuration in which conductive plastic wiring pits for accommodating electrical wiring are provided. However, this is not a method of protecting the electric wiring itself from noise, and therefore, there is a very high possibility that noise is mixed into the electric wiring at a portion exposed from the wiring pit. As described above, the conventional noise countermeasures are effective as a method of protecting the control circuit board itself and the back mechanism panel as a whole from the outside, but even with these methods, abnormal operation of the gaming machine due to noise still occurs. In particular, for electric wiring, electric wires of a general shape in which metal conductors are covered with polyvinyl chloride or the like are used,
No solution is disclosed for noise on the wires and their joints themselves.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to solve the problem of electromagnetic waves propagating from inside and outside a pachinko machine.
An object of the present invention is to provide a pachinko-type gaming machine that can provide a product with high operation reliability by eliminating the influence of static electricity noise on a control mechanism of the gaming machine and that contributes to a longer life of electric members.

[0005]

In order to achieve the above object, according to the present invention, a part or all of electric wiring in a back mechanism panel of a pachinko game machine is electromagnetically shielded by a conductor at an outer periphery thereof. By using the metal conductor, the noise from electromagnetic waves and static electricity from the electric wiring and its joint is prevented from being mixed, and the problem is solved.

Here, the electric wire may be a shielded wire having an outer conductor provided between the inner sheath covering the metal conductor and the outer sheath.

Further, at least a part of the outer conductor is
By connecting to the ground line, noise mixed into the internal metal conductor can be removed, and a higher effect can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. Here, a pachinko machine is cited as a pachinko machine, but the present invention includes, in addition to the pachinko machine, an electric circuit, an electric wiring and a relay base for relaying the electric circuit, and the relay base in the game machine back mechanism panel. A general game machine such as a slot machine having a function of operating an electric member in the game machine can be used.
The embodiment can be appropriately designed and modified without departing from the gist of the present invention.

FIGS. 1 to 3 are a rear view, an external front view, and a wiring block diagram showing an outline of a pachinko machine according to the present invention. On the back of the pachinko machine, the main board (11),
Sound / lamp control board (12), symbol control board (13),
In addition to well-known members that control the game, such as a payout control board (14), a launch control board (15), and a payout apparatus (16), a lamp relay board (17), a SW relay board (18), a frame SW relay board ( A board for relaying each wiring such as 19) and a power supply board (20) for supplying power to the entire gaming machine are provided. Also, on the front of the pachinko machine, a player performs a firing operation of a pachinko ball. The big winning opening (22) arranged on the handle (21), the game board (41), the left and right drop winning opening (2)
3) (23), left and right sleeve winning openings (24) and (24), etc. In addition, along with a windmill (35 ') and a symbol display device (25) that operate as the game progresses, large winning opening LEDs (31) (31) (31), decorative LEDs (32) (32), side lamps (33) (3
3), center LEDs (34), (34), (34), and windmill lamps (35), (35). Further, the gaming machine frame (42) includes award ball lamps (36) (36), frame lamps (37) (37), and a speaker (26).

When the player operates the handle (21),
The state of the handle (21) is transmitted to the firing control board (15), and the firing control board (15) generates a firing signal. A pachinko ball is fired from the firing device based on the firing signal.

[0011] When a hit ball hit into the game board (41) wins a winning opening such as a left sleeve winning opening and the winning opening SW provided in each winning opening turns on, a winning signal is transmitted to the SW relay board (18). ) To the main substrate (11). Main board (1
When 1) receives the winning signal, it generates a prize ball number signal indicating the number of prize balls corresponding to each winning port. Based on the signal, the payout control board (14) drives the payout device to perform a predetermined number of winning ball payout operations.

When a ball hit into the game board (41) passes through gates (27) and (27) installed on the left and right sides of the board, the hit ball is detected by the gate SW and the SW relay board (1) is detected.
The detection signal is transmitted to the main board (11) via 8). The main board (11) performs an internal lottery of a hit or a loss, and when the lottery result is a hit, generates a start opening signal. The signal drives the starting port solenoid via the SW relay board (18) to open the variable blade (28a) provided in the starting port, thereby creating a state where the starting port (28) can be easily won.

When the hit ball hit into the game board (41) wins the starting port (28) and the starting port SW is turned on, the winning signal is the same as when the winning port SW is turned on. Is transmitted to the payout control board (14) to pay out the prize balls from the payout device (16), and the main board (1).
1) performs an internal lottery to determine whether or not to generate a big hit, and executes a symbol changing operation of a symbol display device (25) via a symbol control board (13) based on the lottery result. If the lottery result is a big hit, after stopping the symbol fluctuation operation,
The main board (11) generates a special winning opening release signal. The signal is used to drive the special winning opening solenoid via the SW relay board (18) to open the variable door attached to the special winning opening (22) and to make it easier for the hit ball to win the special winning opening (22). To produce

The number of hit balls that have won the special winning opening (22) is detected by a count SW arranged in the special winning opening, and a detection signal is transmitted to the main board (11), and the main board (11) counts a predetermined number. After exiting, the special winning opening solenoid is driven to close the special winning opening variable door. At this time, when the hit ball passes through a specific area in the special winning opening while the variable door is open, the specific area SW attached in the passage is sensitive, and the main board (11) that has received the sensitive signal receives the variable signal. After the door is closed, the variable door is opened again. This opening / closing operation is continuously performed until a predetermined number of times is reached.

As described above, in a pachinko machine, the operation of each switch, the driving of solenoids and motors, the blinking of an electric lamp, and the like are constantly performed in accordance with the movement of a hit ball or the production of a game state. , Is frequently repeated,
The current flowing in the electric circuit also changes drastically. for that reason,
The inside of the machine is an environment in which a large amount of electromagnetic waves are generated, and noise is a cause of malfunctions in electric circuits.

Further, since a large number of pachinko machines are usually installed in parallel on a game machine installation island (hereinafter, referred to as an island), the above-described noise affects each other between adjacent machines, and electromagnetic waves to the game machine are not affected. The operating environment of the gaming machine is extremely severe because it propagates not only from the inside but also from the outside.

The island is provided with a pachinko ball transport mechanism and a supply device, and the metal balls are supplied to the tank (5) of each pachinko machine.
1) and at the same time inside the pachinko machine,
A large number of metal balls move from the tank (51) to the tank rail (5).
After 2), it flows down to the dispensing device (16). It is known that, as a large amount of pachinko balls are induced, a large amount of static electricity is generated and affects a control mechanism of a game machine.

Conventionally, various measures have been taken to counter the above-mentioned generated noise. In this pachinko machine as well, a conductive shield layer is formed on a control board and the shield layer is connected to a ground line. In this way, noise control of the control board itself is taken. However, as described above, in an environment where electromagnetic waves and static electricity propagate very much, it is inevitable that noise is mixed in from electric wirings and their junctions. In particular, it is known that electric wiring acts as an antenna that picks up noise, and noise countermeasures are indispensable.

Therefore, in the present invention, shield wires shown in FIGS. 4 and 5 are used for electric wiring. FIG.
Uses a flame-retardant polyethylene for the inner sheath (62) covering the inner conductor (61), surrounds the periphery with a braided shield (63) made of copper, and uses a semi-rigid heat-resistant vinyl for the outer sheath (64). ing. FIG. 5 shows a member using a horizontal shield (63 ′) instead of the braided shield (63). These electrical wirings have already been commercialized, are easily available, and have sufficiently withstand practical use. In addition, various types of standard outer diameters of electric wires from 2.2 mm are provided, and the electric wires can be used for all electric wires used in gaming machines.

By using the above-mentioned shielded wire, the inner conductor (61) of the electric wire is shielded from the outside, and the absorption of noise is significantly reduced. At the same time, by connecting a part of the shield (63) (65) of the shield wire to the ground line in the electric circuit, the shield (63) (6)
The noise absorbed by 5) flows to the ground line,
A more complete shield is achieved. As a result, the mixing of noise into the internal conductor is minimized, and the noise that has been mixed from the electric wiring and the junction thereof can be almost completely removed.

Here, in this embodiment, shielded wires are used for all electric wirings, but if necessary, metal wires partially covered with conventional polyvinyl chloride or the like may be used. However, in this case, the electric wiring (7) for relaying the sound / lamp relay board (17) and the speaker (26).
2) and electric wiring (71) (7)
1) It is desirable to limit to a part relatively insensitive to noise such as (71). However, in the actual product inspection process, if it is judged that the influence of noise is small even if conventional wiring members are used, in order to further improve the reliability of the product, shield it in a place that is easily affected by noise. A configuration using a line may be adopted.

The shield wire is not limited to a single wire as shown in FIGS. 4 and 5, but may be a double wire in which a plurality of fine wires are entangled.
Also, using a multi-core shielded wire in which a plurality of inner conductors covered by an inner sheath are collectively wound by an outer conductor, or a plurality of shielded wires collectively covered with a covering member such as vinyl. Is also good.

Regarding the structure of the shielded wire, not only the illustrated example but also a metal conductive wire electromagnetically shielded by an external conductor can be used. That is, the outer conductor is not limited to a braid or a horizontal winding, for example, an outer conductor arranged in a lattice shape,
Various structures may be used, such as those in which conductive wires are entangled irregularly. In addition, the outer conductor may be wound around the metal wire in any form.For example, without providing a shield between the inner sheath and the outer sheath, a shield may be provided inside a single layer of sheath covering the metal wire. It may be provided.

The present invention can be applied not only to the case of designing and manufacturing a new pachinko game machine, but also to the case where a conventional electric wiring is replaced in order to enhance noise suppression of an existing game machine.

As described above, the pachinko gaming machine of the present invention has the following configuration, and thus has the following effects. According to the gaming machine of claim 1, by using a metal conductor electromagnetically shielded by an external conductor for electric wiring, a control mechanism of the gaming machine due to electromagnetic waves generated from inside and outside of the pachinko game machine and electrostatic noise. By eliminating the impact on
It is possible to provide a pachinko game machine that can provide a product with high operation reliability and contributes to a longer life of the electric member.
In addition, since the gaming machine has high resistance to noise, the performance of protecting against fraudulent acts using a radio wave transmitter or the like is improved.

According to the gaming machine of the second aspect, since it is possible to use electric wiring which is already distributed in the market, is easily available, is inexpensive, and has a sufficient shielding effect, it can be newly provided. It can be easily applied not only when designing and manufacturing pachinko game machines, but also when replacing existing electric wiring.

According to the gaming machine of the third aspect, by connecting a part of the external conductor to the ground line, noise mixed in the external conductor can be removed, so that a more complete noise countermeasure can be taken.
