 The present invention relates to an illegal prize ball prevention device for a game machine.

Problems to be Solved by Prior Art and Inventions

In conventional game machines such as pachinko machines, for example,
As shown in Japanese Laid-Open Patent Publication No. 52-31570, a magnetoelectric conversion unit composed of a Hall element and the like, and a bandpass filter for passing only a low frequency component corresponding to the operation of the magnet owner among the voltages generated by the magnetoelectric conversion unit, , A magnet fraud alarm device such as a pachinko playground having a comparator for comparing the filter output with a reference voltage and an alarm circuit operated by the output of the comparator is attached to prevent fraudulent prize ball action by a magnet. . However, in recent game machines, digital electronic circuits using an IC chip are used for the management of winning balls and the driving of throttle devices such as so-called accessories. That is, the symbols displayed on the throttle device are digitally controlled. Further, a coil member for generating an electromagnetic wave is provided as a game ball detecting device for the winning opening, and an electromagnetic wave type of detecting the passage of the game ball by changing the resistance of the coil member due to the electromagnetic wave changing with the passage of the game ball. Various play ball detection devices are attached. In a game machine equipped with the above-mentioned digital electronic circuit, a radio wave is emitted from the outside to electrically destroy the IC chip of the electronic substrate, so that the game ball does not win the prize hole or the accessory. However, there is a possibility that an illegal prize ball will be possible. Further, in a game machine equipped with a game ball detection device that detects the winning of a game ball using electromagnetic waves, when a radio wave is emitted in the vicinity of the game machine, the electric field disturbs the electric field of the game ball detection device. Even if the game ball has not won, there is a risk that a signal is output when it is determined that the game has won. That is, with the digitization of amusement machines, new fraudulent prize ball behavior using radio waves has occurred. However, in the conventional magnet fraud alarm device described above,
It was completely impossible to prevent new illegal prize balls using radio waves. The present invention has been invented in order to solve the above-mentioned conventional drawbacks, and an object thereof is to prevent an illegal prize ball of a game machine which effectively prevents a new illegal prize ball action using a radio wave. To provide a device.

Each display member of the throttle device 5 of the accessory 7 is digitally controlled by an electronic circuit (not shown) mounted. A large number of IC chips are attached to this electronic circuit to form a digital control circuit. An illegal prize ball prevention device described later on a part of the game machine 1
11 antennas 13 are attached. A detecting device 15 as a detecting means is connected to the antenna 13, and the detecting device 15
The radio wave received by 15 is detected, and when the radio wave has a required frequency, a detection signal of a voltage corresponding to the electric field strength of the radio wave is output. This detection device 15 is set to the VHF or UHF band, which may damage the IC chip of the electronic substrate. A comparison circuit 17 as a discriminating means is connected to the detection device 15, and the comparison circuit 17 outputs a detection signal when the voltage of the detection signal from the detection device 15 is equal to or higher than a preset reference voltage Vref. To do. That is, the detection signal is output only when the electric field strength of the received radio wave may electrically damage the IC chip of the electronic substrate. A timer circuit 19 is connected to the comparison circuit 17, and is configured to output an output signal only when the detection signal from the comparison circuit 17 is continuously input for a required time. An output circuit 21 as an output means is connected to the timer circuit 19, and an alarm device such as an alarm device or a warning light 23 is provided on the basis of an output signal from the timer circuit 19 for a required time or the output circuit 21.

The warning member 23 is provided so as to correspond to each of the corresponding amusement machines 1 arranged on the arrangement table, or so as to correspond to each of the amusement machines 1 at a counter that manages the arrangement stand or the entire playground. This makes it possible to identify which game machine 1 in the playground the radio wave was emitted from. Next, the operation of the illegal prize ball prevention device 11 configured as described above will be described. When a radio wave is emitted for the purpose of destroying the electronic board mounted on the game machine 1, it is input via the antenna 13. The detected radio wave is detected by the detection device 15. This detection device 15 is highly likely to destroy the IC chip of the electronic board,
Only high frequency radio waves are detected and a detection signal of a voltage corresponding to the electric field strength of the radio waves is output. Therefore,
The detection of low frequency radio waves, which are less likely to damage the IC chip of the electronic board, is regulated, and various external noises are selected. The detection signal from the detection device 15 is detected by the comparison circuit 17 as an external noise having a weak electric field strength by outputting the detection signal only when the voltage has a sufficient electric field strength to destroy the IC chip. Are sorted out. The output signal is output only when the detection signal from the comparison circuit 17 continues for a required time. Therefore, when the emitted radio wave has an electric field strength that is not sufficient to destroy the IC chip, the output of the output signal is regulated to separate it from external noise. When an output signal is output from the timer circuit 19, the output circuit 21 activates the warning member 23 so that it is possible to determine to which game machine 1 the radio wave for the false prize ball is emitted. Warn workers. As described above, in this embodiment, the throttle device 5 or the accessory 7

Are attached so as to substantially coincide with the inner peripheral surface of the through hole 33a. A coil 37 is wound around the core 35, and when the coil 37 is energized, electromagnetic waves are generated in a direction orthogonal to the axis of the through hole 33a. Further, inside the housing 33, a substrate 39 of an output circuit incorporating a detection circuit, an amplification circuit and the like is attached. When a game ball is won at the winning port 3 or the winning port of the accessory 7, the electric field of the electromagnetic wave generated from the coil 37 changes as the metallic playing ball passes through the through hole 33a, so that the coil is changed. 37
The electric resistance of has changed to detect the passage of a game ball. Further, the antenna 13 of the above-mentioned illegal prize ball prevention device 11 is attached to the board surface of the game machine 1, and the detection device 15, the comparison circuit 17, the timer circuit 19, the output circuit described above are attached to the antenna 13.
21 and the warning member 23 are connected. Next, the operation of the illegal prize ball prevention device 11 configured as described above will be described. A radio wave having a required electric field strength or more is generated near the game machine 1 at a frequency corresponding to the electromagnetic wave output from the coil 37. When fired, the electromagnetic waves from the coil 37 are disturbed by the radio waves and the electric resistance of the coil 37 changes, so that the game ball passes, and thus the game ball wins the prize hole 3 or the prize hole of the accessory 7. Notwithstanding, there is a possibility that a prize detection signal is output to give a prize ball or the guide member of the accessory 7 is operated. At this time, similar to the above-described operation, when the radio wave is received by the antenna 13, it is determined whether the radio wave has a required frequency and a predetermined electric field strength or more, and the game ball detection device 31 may malfunction. In the case of a certain radio wave, the warning member 23 can be activated to warn the operator. In the invention according to claim 1, the winning opening 3 or the accessory 7
Even if the game machine 1 is provided with the game ball detection device 31 according to claim 2 in the discharge passage communicating with the winning opening of the game machine, the through hole 33a is also provided.
