Abstract

PROBLEM TO BE SOLVED: To prevent a solenoid from being irregularly driven by a power supply voltage commonly used inside a game machine. SOLUTION: Since the voltage for driving the solenoid 6 is 36 V DC, even if 12 V DC is applied thereto as shown by a broken line in the figure, it cannot provide a sufficient current and consequently a desired driving force. As a result, no irregular game comes into effect. In addition, a switching element TR2 for energizing the solenoid 6 is arranged between and connected to the high-side terminal of the solenoid 6 and 36 V DC, so that it is not so easy to prepare unauthorized wiring equivalent to the ON-state of the switching element, as in conventional examples wherein the switching element is arranged at the side of the low-side terminal thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine having a solenoid for opening and closing a winning opening.

[0002]

2. Description of the Related Art Conventionally, a winning opening solenoid has been used to operate a winning opening of a pachinko machine. The winning opening solenoid is driven by DC 12V supplied from the main board, and moves the winning opening through the plunger.

[0003]

However, the DC 12 volt for driving the above-mentioned winning opening solenoid is commonly used not only in the main board but also in the peripheral sub-boards inside the gaming machine, so that the sub-board is used. DC being supplied
It was possible to illegally open the winning opening solenoid by using 12 volts.

Further, since a switching element is usually connected between the low side terminal of the winning opening solenoid and the ground, even if the switching element is not turned on, the low side of the winning opening solenoid is connected. It is possible to energize the winning opening solenoid by grounding the terminal with a lead wire or the like.

Incidentally, such a problem is not limited to the winning opening solenoid, but is a problem applicable to all solenoids used in the game machine.

Therefore, in view of the above points, an object of the present invention is to
It is an object of the present invention to provide a gaming machine configured to prevent illegal driving of a solenoid by using a power supply voltage commonly used inside the gaming machine.

[0007]

In order to achieve the above object, the present invention according to claim 1 is provided with a solenoid operated by a dedicated solenoid drive voltage different from the voltage used in the game machine. A gaming machine, wherein a switching circuit for energizing the solenoid is provided on the high side terminal side of the solenoid.

According to a second aspect of the present invention, in the gaming machine according to the first aspect, a voltage higher than a voltage used in the gaming machine is used as the dedicated solenoid drive voltage.

According to a third aspect of the present invention, in the gaming machine according to the second aspect, in addition, a booster circuit for inputting a voltage used in the gaming machine and outputting the dedicated solenoid drive voltage is provided. It is built in a control board that controls the solenoid.

The present invention according to claim 4 provides the gaming machine according to any one of claims 1 to 3, wherein the solenoid is a winning opening solenoid of a pachinko machine.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a front view of a pachinko gaming machine 1 to which the present invention is applied. In this figure, special symbol display device 1
Each symbol and various characters are displayed on the LCD panel 110 included in 00.

Reference numeral 200 is a starting winning opening through which the game ball 201 wins. The starting winning opening 200 also functions as an ordinary electric accessory (electric tulip).

Reference numeral 202 is a variable winning ball device (attacker) having a special winning opening 203. The special winning opening 203 is provided with a continuous winning area (V zone) 204.

Reference numeral 205 is a so-called mini digital type ordinary symbol display device. 206 is a normal symbol operation gate (through chucker).

Reference numeral 207 is a lamp display device. 208

FIG. 2 shows solenoids for moving various winning openings and drive circuits thereof. In this figure, 2
Is a power supply unit provided inside the gaming machine, DC1 for inputting 24V AC to operate each control board
Output 2V. D output from this power supply unit 2
The C12 bolt is a main board that controls opening and closing of the winning opening 4, a pattern control board 8 that controls display of symbols, a lamp control board (not shown) that controls lighting of various lamps, and a voice that controls output of audible sound. It is supplied as a common operation power supply to various control boards such as a control board (not shown).

The winning opening solenoid 6 for opening and closing the winning opening has a voltage of 12 VDC or more (for example, DC3).
Use a type that operates normally at 6 V) and cannot obtain a sufficient driving force at 12 V DC common power supply.
That is, in this embodiment, a solenoid having a rated voltage of DC 36 V is used. Therefore, a DC-DC converter 4B for generating DC36V from DC12V is built in the main board 4 for controlling the winning opening solenoid 6, whereby the solenoid drive voltage DC3 is generated.
Get 6 Volts.

When a winning opening condition such as a jackpot is established by the regular game procedure, the CP in the main board 4
The switching element TR2 is turned on by driving the switching element TR1 from U4A. As a result, 36V DC is applied to the solenoid 6, and the plunger (not shown) of the solenoid operates.

As described above, since DC 12V is distributed to each control board, the wiring of the game machine is illegally processed and the DC 6 is directly applied to the solenoid 6 as shown by the broken line in FIG.
There is a risk that a bolt will be applied. However, since the drive voltage of this solenoid 6 is DC 36 V, even if DC 12 V is improperly applied, sufficient current does not flow, so the desired drive force cannot be obtained, and an illegal game cannot be established. Moreover, since the switching element TR2 for energizing the solenoid 6 is connected between the high-side terminal side of the solenoid 6 and DC 36 V, switching is performed as compared with the conventional example in which the switching element is provided on the low-side terminal side. It is not easy to carry out illegal wiring equivalent to the ON state of the device.

Since the main board 4 for controlling the winning opening solenoid 6 contains software for controlling the entire game such as a big hit, the case of the main board is easy for the purpose of preventing software tampering. It has a structure that does not open. Therefore, it is considered very unlikely that the internal DC 36 V is illegally taken out and directly applied to the solenoid.

In the above-described embodiments,
Although the solenoid drive voltage is generated in the main board 4, the power supply unit 2 generates the solenoid drive voltage,
It is also possible to supply to. However, in this case, the possibility of improper driving increases as compared with the above-described embodiment.

Further, a solenoid having a drive voltage of DC 12 V or less is used, and a protection circuit, a fuse, etc., which prevent the solenoid drive current from flowing when DC 12 V is applied, are formed integrally with the solenoid. It is also possible.

[0024]

As described above, according to the present invention, the power supply voltage commonly used in the gaming machine is used.
It is possible to prevent illegal driving of the solenoid. That is, it is possible to perform a sufficient protection function against an illegal operation such as illegally replacing the wiring inside the gaming machine and directly applying it to the solenoid.
