``Effect'' When a current is passed through the folded transmission line and a magnetic field is generated,
An electromotive force is generated in the receiving line electromagnetically coupled to the transmitting line due to mutual induction. At this time, when a metal such as a pachinko ball approaches a metal sensor, an eddy current is generated on the surface of the metal in a direction that cancels out the magnetic flux caused by the metal sensor.

The impedance of the transmission line changes due to the influence of the eddy current, causing the current to change. Correspondingly, the receiving line changes the magnitude of the electromotive force. By detecting this change, it is possible to determine whether metal is approaching.

When a detection matrix is configured by having multiple transmission lines and reception lines arranged in a crossing direction, the transmission line and reception line whose electromagnetic characteristics have changed are detected, and the detection matrix is constructed from the crossing position. It is possible to understand the position of the metal as coordinates.

When the ends of the transmitting line and the receiving line are placed on one end of the board as transmitting terminals and receiving terminals, connect them to the transmitting connector and receiving connector with the transmitting terminal and receiving terminal facing downward. Then, you can use the weight of the board to make sure the connection. In particular, when the front glass of a pachinko game machine is used and the transmitting connector and receiving connector are provided at the bottom inside of the mounting frame, the transmitting terminal and receiving terminal must be connected at the same time when the front glass is installed. It comes.

In the case of a metal detection device, a decoder that operates based on control signals from a main control device such as a central computer controls transmission drivers to operate sequentially, so that the transmission drivers sequentially connect to multiple transmission lines at a predetermined period. Input the signal.

On the receiving line side, a converter receives the electromagnetic characteristic value of each of the plurality of receiving lines and converts this electromagnetic characteristic value into a signal that can be handled. The multiplexer receiving the converted signal from each receiving line sequentially outputs the signal from each receiving line at a predetermined period.

When a pachinko ball hits the intersection of the transmitting line and the receiving line, the electromagnetic characteristics there change, and this change occurs in the receiving line at that point, and the transmitting line at that position and the corresponding receiving line are scanned. It can be detected by nicking.

By attaching a metal sensor to the front glass of a pachinko game machine, the position of the pachinko balls can be known at all times based on the coordinates.

Metal sensors can track the movement of pachinko balls as changes in coordinates on the board of a pachinko game machine, and monitor the progress of the game by placing metal sensors at important points on the board, such as safe holes and out holes. Ball in.

The information can be used to know the status of the balls being put out, to manage the ball delivery, to check for irregularities due to fraud, and to use as data for nail adjustments, etc.

The thickness of the conductor constituting the receiving line 26 also has a large effect; if it is thin, the impedance will be too high, and if it is thick, the inner diameter of the button will become small, resulting in poor sensitivity. Furthermore, the detection matrix 20 includes an inner glass body 1 that covers the board surface 11.

Is there something that can detect this?

Contrary to the above synchronization mode, for one transmission of one transmission line 22 among the plurality of transmission lines 22, the reception line 26.26

That is, when a sine wave signal is transmitted to each of the plurality of transmission lines 22 of the detection matrix 20, the reception line 26
．． A predetermined impedance value is generated in the plurality of transmission lines 22 by inductive coupling between the transmission lines 26-26 and the transmission lines 22, 22, . Note that since the voltage waveform 81 to the transmission line 22 is a continuous sine wave centered on OV, it does not generate noise like a square wave and prevents the influence on other devices such as the CPU unit 30. Something comes up.

When a pachinko ball approaches and passes the detection unit 20a, the electromagnetic characteristics of the plurality of transmission lines 22, specifically the impedance value, change, and the electromagnetic characteristics of the corresponding receiving line 26, specifically the receiving current, also change. , -T: is applied from the converter 51 to the multiplexer 52 as described above. Since the number of detection units 20a is 1024 in total, including the transmission line 22 or 32 rows and the reception line 26 or 32 column, it will be detected no matter which safe hole 14a and out hole 15 of the pachinko ball or board 11 it passes through. Something comes up.

The output of multiplexer 52 is connected to impedance converter 54.
The external connection connector 38
The signal then enters the impedance matching trifer 32 on the CPU unit φO side, where impedance matching is performed. The DCC off-seller converter 33 next to the inductance matching link tricycle 32 is connected to the detection matrix 20.
It receives only the reaction wave out of the output from and outputs it to the halt section 34.

The halt section 34 transfers the data sent at high speed to the next A.
A/D conversion by the A/D converter 35 is temporarily held and stored.

The A/D converter 35 converts the analog signal from the detection matrix 20 into a digital signal in units of predetermined bits, such as 12 bits, and sends the digital data to the CPU unit 30 via the data bus. Holt section 34.
The operation of the A/D converter 35 is controlled by the logic controller 3.
1 or a signal from a timing generator 36.

A separate output terminal may be provided in the A/D converter 35, and the movements of all pachinko balls on the detection matrix 20 may be stored for a long time.

By detecting the transmitting line 22 where the impedance has changed and the receiving line 26 where the receiving current has changed, the position of the pachinko ball can be grasped as the coordinates of the position where these intersect.

Note that the detection matrix 20 includes a transmission line 22 and a reception line 26.
Because they are arranged in U-turns in parallel folds and are perpendicular to each other, the pattern is simple and unobtrusive, and can be easily manufactured using wire material such as copper wire. In addition, the transmission line 22 and reception &i26 of the detection matrix 20 are the transmission line 2
Compared to the case where the receiving line 2 and the receiving line 26 are bent, the length of the line is shorter and the direct current resistance is lower, so the response sensitivity is better.

Moreover, the transparent conductive film 28 on the surface of the outer glass plate 17c is

It has a bidirectional RAM 676 that is sent to the PU unit.

The bidirectional RAM 676 has an internal counter,
All processing of pachinko ball matrix data is performed by the counter. Furthermore, the CPU memory control boat 72 has a power supply unit 677.

The voltage waveform 81 to the transmission line 622 has a frequency llR1
A continuous sine wave centered on the OV of ~1.3 MHz is suitable. Pachinko game @10 generates noise of various frequencies depending on the model. If the frequency of this noise and the transmission frequency to the detection matrix 620 match or are close to each other, the accuracy of detecting pachinko balls will deteriorate significantly. Therefore, depending on the model of pachinko game machine IO, prepare several metal detection devices with a transmission frequency that does not match or approach the frequency of the noise in the frequency band of 1 to 1.3 MHz, and install them in the pachinko game machine. Depending on the machine, select and install a metal detection device with a transmission frequency suitable for the device.

Next, the action will be explained.

Address signals and control signals from the CPU unit are sent to the CPU connector 662 in the same manner as in the first embodiment.
The information is then transmitted to the pachinko game KIO.

In the pachinko game 111O, on the transmission side, the sequence control circuit 663 receives a start signal, divides the 16 MHz original clock as necessary, and outputs a transmission clock. The transmission clock from the sequence control circuit 663 is
After the digital signal is waveform-shaped into an analog signal by the bandpass filter 664, it is amplified by the amplifier 665 and sent to the transmission connector 641.

2 (step 691 in Fig. 29).
reference).

On the receiving side, as shown in FIG.
The current that is the electromagnetic characteristic value appearing in the CT sensor 65
1, it is amplified ten times.

Since amplification is performed by the CT sensor 651, there is no need to increase the amplification degree of the amplifier on the receiving side. C
Since the amplification by the T sensor 651 is performed by insulating each receiving line 626 and the analog multiplexer 652,
It can be done without making any noise. As a result, compared to the case where an OP amplifier is used, it is possible to prevent the generation of noise and DC drift due to the OP amplifier itself, and it is possible to improve the detection accuracy of the received signal.

By using the CT sensor 651, there is no need to use an OP amplifier, which is generally larger than a CT sensor, and the matrix I10 transmitting/receiving boat 71 can be made smaller.

The analog multiplexer 652 switches the signals from each receiving line 626 that have passed through the CT sensor 651 using a channel switching logic 654, and sequentially outputs the signals at a predetermined period. The signal from analog multiplexer 652 is amplified 100 times by amplifier 653 (see step 692 in FIG. 29).

The received signal passes through a reception connector 655, an amplifier 671, and a bandpass filter 672, where it is amplified and detected. The received signal from bandpass filter 672 is
As shown in FIG. 30(A), it is an analog signal with several cycles as one scan. This analog signal is subjected to waveform shaping by a full-wave rectifier/amplifier 673, as shown in FIG. 30(B).

The signal from the aftereffect rectifier/amplifier 673 is averaged by an integral process by a low-pass filter 674a, as shown in FIG. 30(C).

Furthermore, a 60-pass filter 674b is used (D
), averaging is performed. As a result, noise is also averaged with the received signal, or the amount of noise is extremely small compared to the signal, and errors due to noise can be ignored. When performing averaging using the low-pass filters 674a and 674b, the band-pass filter 6
This is because after passing through 72, there is no noise sufficient to cause an error. For this purpose, the transmission frequency is selected to be a frequency that is not affected by the noise of the pachinko game @io, or the band pass filter 672 is selected to be a frequency suitable for the transmission frequency.

The received signal is then sent to A/D converter 675. The A/D converter 675 converts the signal from the detection matrix 620 into a digital signal in units of predetermined bits, such as 12 bits, for example, and records the received data in the bidirectional RAM 676 under the control of the sequence control circuit 676 (see FIG. 29). (see step 693), this processing speed is.

This is a high speed of 25,000 times in 18 days. Bidirectional RAM676
is C by the write signal from the sequence control circuit 676.
After recording the received data regardless of the operation of the PU unit 30, the address is changed by inputting the l clock.
The capacity of the bidirectional RAM 676, which is increased by 1 (see step 694 in FIG. 29), is, for example, 2048 hides.

In this way, the analog multiplexer 6 of the receiving circuit 650
52 switches the signal from each receiving line 626 (see step 695 in FIG. 29), and repeats the above steps 32 times in response to the 32 receiving lines 626 (step 69 in FIG. 29).
6), and after repeating 32 times, switch the analog multiplexer 644 of the transmitting circuit 640 or the transmitting line 622 (see
(see step 69) in FIG. 29), the signal processing is repeated again.

The CPU unit reads the data regarding the position of the pachinko balls recorded in the bidirectional RAM 676 according to the read start signal as necessary, and performs arithmetic processing.
The CPU unit repeats this process, and each circuit of the CPU memory control board 72 and the CPU unit are as follows:
Since processing is performed while ignoring mutual waiting time, CP
The burden on the U unit 30 is reduced, and the CPU unit 3
It is possible to increase the processing speed of o.

For the CPU unit 30, if the ball detection algorithm is simple, an inexpensive 8-bit CPU is sufficient; if a complex algorithm is required, a 5-bit high-speed processing is required. , it is better to select one that uses a 16-bit CPU. In either case, the speed of scanning pachinko balls depends on the CPU used for scanning.
Since it does not go through U, it is not affected by the CPU.1 In this way, a current is passed through the folded transmission line 622 to generate a magnetic field, and mutual induction is generated in the reception line 626 which is electromagnetically coupled to the transmission line 622. When an electromotive force is generated by the action, when a pachinko ball is applied to the detection unit 620a, an eddy current is generated on the surface of the metal pachinko ball in a direction that cancels out the magnetic flux produced by the detection matrix 620. As a result, the impedance, which is an electromagnetic characteristic of the detection matrix 620, changes at that position, and the magnitude of the electromotive force in the receiving line 626 changes. 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 is determined by the receiving lines 626, 626, whose impedance has changed, and the transmitting line 62 at that position.
2,622-... can be understood as the coordinates of the intersecting position. The number of detection units 620a is sent @@62
Since there are 32 rows of 2 and 32 columns of reception lines 626, for a total of 1024 pieces, which safe hole 14 on the pachinko ball or board 611?
It is possible to detect even if the light passes through a and the out hole 15.

Note that the voltage waveform 81 to the transmission line 622 is a continuous sine wave centered on ov, so it does not generate noise like a square wave, and prevents the influence on other devices such as the CPU unit. I can do it.

In addition, the voltage waveform 81 is in the transmission frequency band of 1 to 1.3 MH.
z, it is possible to increase the response sensitivity to receive noise from peripheral devices of the pachinko game machine 10. Note that components that can process signals in a frequency band of 1 to 1.3 MHz are cheaper than components that can process signals in a higher frequency band. Additionally, depending on the model of the pachinko game allO, a metal detector with a transmission frequency that matches or does not come close to the noise frequency is selected, making it possible to obtain good pachinko ball detection accuracy without being affected by noise. It comes.

Moreover, the transparent conductive film 28 on the surface of the outer glass plate 17c is
It has the effect of shielding the electrical influence of metals and derivatives from the outside and increasing the reaction sensitivity to pachinko balls.

The CPLI unit is recorded in the RAM cart 73.
The detection unit 620a corresponds to important points such as the safe holes 14a, 14a-... and the out hole 15.
