The bidirectional RAM 676 has a counter inside, and all processing of matrix data of pachinko balls is performed by the counter. Further, the CPU memory control board 72 has a power supply unit 677.

As the voltage waveform 681 to the transmission line 622, a frequency of 1 to 1.3 M
A continuous sine wave centered at 0 V at Hz is preferred. The pachinko game machine 10 generates noise of various frequencies depending on the model. If the frequency of this noise matches or approaches the transmission frequency to the detection matrix 620, the accuracy of detecting a pachinko ball will be significantly degraded. Therefore,
Depending on the model of the pachinko game machine 10, several types of metal detection devices having a transmission frequency that does not match or approach the noise frequency in the frequency band of 1 to 1.3 MHz are prepared in advance,
According to the pachinko game machine 10 to be mounted, a metal detection device having a transmission frequency suitable for the pachinko game machine 10 is selected and mounted.

 Next, the operation will be described.

The address signal and the control signal from the CPU unit are transmitted to the pachinko game machine 10 via the CPU connector 662.

In the pachinko game machine 10, on the transmission side, the sequence control circuit 663 receives the start signal, divides the original clock of 16 MHz as necessary, and outputs the transmission clock. The transmission clock from the sequence control circuit 663 is shaped by a bandpass filter 664 from a digital signal to an analog signal, then amplified by an amplifier 665, and sent to a transmission connector 641.

Further, the transmission signal is amplified by the amplifier 642 in the transmission circuit 640. The analog multiplexer 644 is a channel switched by the channel switching logic 643,
The totem pole driver 645 sequentially operates, and thereby the totem pole driver 645 sequentially outputs the signal amplified by the amplifier 642 to the transmission line 622 at a predetermined cycle (see step 691 in FIG. 14).

On the receiving side, as shown in FIG.
The current which is an electromagnetic characteristic value appearing is amplified 10 times by the CT sensor 651. Since amplification is performed by the CT sensor 651, it is not necessary to increase the amplification of the amplifier on the receiving side. The amplification by the CT sensor 651
And the analog multiplexer 652 are insulated from each other, so that the operation can be performed without generating noise. As a result, as compared with the case where an OP amplifier is used, it is possible to prevent noise and DC drift from occurring due to the OP amplifier itself, and it is possible to improve the detection accuracy of a received signal. By using the CT sensor 651, it is not necessary to use an OP amplifier that is generally large in comparison with the CT sensor, and the matrix I / O transmission / reception board 71 can be reduced in size.

The analog multiplexer 652 switches signals from the respective receiving lines 626 that have passed through the CT sensor 651 by the channel switching logic 654, and sequentially outputs the signals at a predetermined cycle. The signal from the analog multiplexer 652 is amplified 100 times by the amplifier 653 (see step 692 in FIG. 14).

The reception signal is amplified and detected through a reception connector 655, an amplifier 671, and a bandpass filter 672. The received signal from the band-pass filter 672 is an analog signal in which several cycles constitute one scan, as shown in FIG. This analog signal is subjected to waveform shaping by a full-wave rectifier / amplifier 673 as shown in FIG. 15 (B).

The signal from the full-wave rectifier / amplifier 673 is averaged by an integration process as shown in FIG. 15C by a low-pass filter 674a.
At 4b, averaging is performed as shown in FIG. 15 (D). As a result, the noise is also averaged with the received signal,
The amount of noise is extremely small compared to the signal, and errors due to noise can be ignored. Low-pass filter 674
This is because, when averaging is performed by a and 674b, since the noise has already passed through the bandpass filter 672, there is no noise enough to cause an error. For this reason, the transmission frequency is selected to be a frequency that is not affected by the noise of the pachinko game machine 10.
For 2, a signal suitable for the transmission frequency is used.

Next, the received signal is sent to A / D converter 675. A /
The D converter 675 converts a signal from the detection matrix 620 into a digital signal in a predetermined bit unit, for example, 12 bits, and controls the sequence control circuit 676 to record the digital signal in the received data bidirectional RAM 676 (see FIG. 14, step 693 in FIG. 14). ). This processing speed is as high as 25,000 times per second. The bidirectional RAM 676 records received data irrespective of the operation of the CPU unit 30 by a write signal from the sequence control circuit 676, and then inputs one clock to increase the address by +1 (see step 694 in FIG. 14). ). The capacity of the bidirectional RAM 676 is, for example, 2048 bytes.

Thus, the analog multiplexer 652 of the receiving circuit 650
Switches the signal from each reception line 626 (step 6 in FIG. 14).
95), and repeats the above steps 32 times in accordance with the 32 reception lines 626 (see step 696 in FIG. 14). After 32 repetitions, the analog multiplexer 644 of the transmission circuit 640 switches the transmission line 622 (see step 697 in FIG. 14), and repeats the signal processing again.

The CPU unit reads data relating to the position of the pachinko ball recorded in the bidirectional RAM 676 by a read start signal as necessary, and performs an arithmetic process. Then, the CPU unit repeats this processing. Each circuit of the CPU memory control board 72 and the CPU unit perform processing while ignoring each other's waiting time, so that the load on the CPU unit 30 is reduced and the processing speed of the CPU unit 30 can be increased.

If the algorithm of ball detection is a simple one, it is sufficient to use an inexpensive 8-bit CPU. If a complicated algorithm is required, the CPU unit 30 performs high-speed processing. It is better to select one that uses a 16-bit CPU. In any case, the scanning speed of the pachinko ball is not affected by the CPU because the scanning is not performed via the CPU.

Thus, when a current is caused to flow through the folded transmission line 622 to generate a magnetic field, and the reception line 626 electromagnetically coupled to the transmission line 622 generates an electromotive force by mutual induction,
When a pachinko ball is applied to the detection unit 620a, an eddy current is generated on the surface of the pachinko ball, which is a metal, in a direction to cancel the magnetic flux by the detection matrix 620. As a result, the impedance, which is the electromagnetic characteristic of the detection matrix 620, changes at that position, and the reception line 626 changes the magnitude of the electromotive force. At this time, the transmission lines 622, 622 ... and the corresponding reception lines 626, 626 ...
Can be detected by scanning.

Therefore, the position of the pachinko ball can be grasped as the coordinates of the position where the reception lines 626, 626... Where the impedance has changed and the transmission lines 622, 622. The number of detection units 620a is 32 for the transmission line 622 and 32 for the reception line 626, for a total of 1024, so that the pachinko ball can be detected even if it passes through any of the safe holes 14a and the out holes 15 of the board 611. it can.

Since the voltage waveform to the transmission line 622 is a continuous sine wave centered at 0 V, there is no generation of noise such as a rectangular wave, and it is possible to prevent the influence on other devices such as the CPU unit. it can.

In addition, since the voltage waveform has a transmission frequency band of 1 to 1.3 MHz, noise from peripheral devices of the pachinko game machine 10 is not easily received, and the response sensitivity can be increased. Note that components that can process signals in the frequency band of 1 to 1.3 MHz are less expensive than components that process signals in the higher frequency band. In addition, according to the type of the pachinko game machine 10, a metal detection device having a transmission frequency that does not match or approach the frequency of the noise is selected, so that good pachinko ball detection accuracy can be obtained without being affected by noise. Can be.

In addition, the inner protective glass plate 617a and the outer glass plate 617c
Can protect the transmission line 622 and the reception line 626 from physical damage due to impact or the like, corrosion from dirt, dust, oxidation and the like, and extend the durability of the detection matrix 620.

The transparent conductive film 628 on the surface of the outer glass plate 617c is
It has the effect of shielding the electrical effects of metals and derivatives from the outside and increasing the reaction sensitivity to pachinko balls.

The CPU unit has a safe hole recorded on the RAM card 73.
The data at the positions of the detection units 620a, 620a, etc. corresponding to the key points such as 14a, 14a, and the out hole 15 are read out, and the movement of the pachinko game machine 10, such as the state of pachinko balls entering the board 11, is described. The progress of the chasing game is monitored as a change in coordinates. By knowing the situation of incoming balls, outgoing balls, and the like, it is possible to use them as data for nailing control, checking for abnormalities due to improper management, illegal operations, and the like. The RAM card 73 may be replaced with a new one when the new pachinko game machine 10 monitors the state of the insertion of pachinko balls. RAM card 73 is the same type of pachinko game machine 10
, One card can be copied and manufactured.

And the connection can be made simultaneously when the inner glass body 617 is mounted on the mounting frame.

To replace or mount the inner glass body 617 provided with the detection matrix 620, the transmitting connector 67a and the receiving connector 67b are detachable, and the inner glass body 617 is mounted on the transmitting circuit 640 of the mounting frame.
And easy to remove from the receiving circuit 650, it is easy to replace the failed detection matrix 620,
Attachment of the detection matrix 620 to a pachinko game machine not equipped with the detection matrix 620 can be easily performed.

Further, since the folded portion 61 of the transmission line 622 and the reception line 626 is formed by a conductor pattern, the production of the transmission line 622 and the reception line 626 is easy, and the transmission line 622 and the reception line 62 are formed.
