Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a fraud prevention device for pachinko machines.

(Conventional technology) Conventional fraud prevention devices in pachinko machines include:
When a customer touches the glass that covers the safe hole on the front of the pachinko machine,
When there is a fraudulent act in which the magnets are placed close together or in close contact with each other to ensure that pachinko balls that are continuously being driven into the safe hole are detected, the magnetism is detected and
There was something that could shut down the power circuit of a pachinko machine.

Furthermore, various devices for operating the machine are packed into the back of the pachinko machine so that there is no room for an upright cone, and it would be difficult to install additional devices. There were many deficiencies, such as complications and adverse effects on existing mechanisms.

(Problems that the invention attempts to solve) This invention minimizes the number of parts used, reliably and quickly detects and receives fraud prevention, and alerts store staff etc. to this as an alarm sound. In addition to achieving the purpose of preventing fraud, this invention is also extremely easy to install, reducing construction costs, and does not adversely affect existing devices installed on the back of pachinko machines. The purpose of this invention is to obtain a fraud prevention device for pachinko machines that do not allow unauthorized use.

(Means for solving the problem) However, the present invention is a fraud prevention device for a pachinko machine that uses a detector that detects a magnet approaching or brought close to the glass that covers the safe hole on the front of the pachinko machine, and a detector that simultaneously emits a radio signal. A detector and a connected wireless oscillator are mounted on the back of the pachinko machine, and a receiver and antenna are mounted on the island to receive the signal and continue to sound an alarm for a predetermined period of time. This is a fraud prevention device for pachinko machines.

(Example) a is a pachinko machine, 1 is the back side of the pachinko machine a,
2 is a handle, 3 is a magnet, 4 is an island, and 5 is a magnetic detector attached to the back side 1 of the pachinko machine a.
Reference numeral 6 denotes a wireless oscillator attached to the back of the pachinko machine a, which is connected to the magnetic detector 5, and has the following configuration. The oscillator 6 passes the magnetism detected by the magnetic detector 5 through a modulation section 7 and converts it into a signal.
Oscillation antenna 9 that connects this signal to oscillation section 8
Make it oscillate more. 10 is a power supply section connected to the modulation section 7 and the oscillation section 8. The above is the configuration of the oscillator 6. 11 is a receiver attached to the island section 4,
It consists of the following composition. That is, in the device 11, the radio waves oscillated from the oscillator 6 are received by the receiving section 13 via the receiving antenna 12 wired to the island section 14, and detected by the detecting section 14. Next, an alarm buzzer 16 connected to the detection section 14 by an output section/timer 15 starts sounding for a certain period of time. 1
Reference numeral 7 denotes a power supply section connected to the receiving section 13, the detecting section 14, and the output section/timer 15. The receiver attached to the island portion 4 is configured as described above.

(Function) To explain the function of the present invention, if a customer maliciously attempts to put a pachinko ball into the safe hole, the magnet 3 approaches the front of the pachinko machine a near the hole, or comes close to the glass surface. Pachinko machine a
The magnetic detector 5 attached to the back surface 1 acts,
Magnetism is detected, and the magnetism is converted into radio waves by the modulation section 7 and oscillation section 8, which constitute the wireless oscillator 6, and the oscillation antenna 9 oscillates radio waves at a predetermined frequency.
At the same time that the installed receiver 11 receives this radio wave via the antenna 12 attached to the island portion 4, the alarm buzzer 16 continues to sound for a predetermined period of time. To explain this process in detail, radio waves are received by the receiving section 13 and the detecting section 14 via the receiving antenna 12, and a detection operation is performed. Next, the output unit/timer 15 is activated and the alarm buzzer 16 continues to sound for a certain period of time. Upon hearing this warning, the store clerk discovers the pachinko player who is cheating and takes appropriate measures.

Note that the alarm buzzer 16 of the present invention is equipped with a timer, so the alarm sounds only for a predetermined time.

(Effects) (1) The present invention is as described above, and is particularly effective against complicated devices such as anti-tamper devices in conventional pachinko machines, which shut off the power to the pachinko machine and disable the firing of pachinko balls. Unlike the Pachinko machine, it functions well with a small number of parts, simply installing a magnetic detector and oscillator on the back side, and an antenna and receiver on the island, and is extremely easy to install. It has the advantage that it does not adversely affect the various existing devices installed on the back side, and it also has the advantage that construction costs can be significantly reduced compared to conventional methods.

(2) Furthermore, unlike conventional fraud prevention measures, this invention completely eliminates the complicated work from turning off the power to repairing it, so it has the advantage of killing two birds with one stone by reducing the labor of store staff. It also has
