Next, the operation will be described. CPU unit 30
Address and control signals from the CPU
The signal is transmitted to the matrix sensor 20 via the connector 46.

In the matrix sensor 20, on the transmitting side, the sequence control circuit 47 receives a start signal and outputs a 16 MHz signal.
The transmission clock is output by dividing the original clock of z as necessary. The transmission clock from the sequence control circuit 47 is subjected to waveform shaping from a digital signal to an analog signal by a band-pass filter 48, amplified by an amplifier 49, and sent to a transmission connector 41.

In the matrix sensor 20, the transmitting circuit 40
When a signal of a predetermined frequency is sequentially transmitted to a plurality of folded transmission lines 22 to generate a magnetic field, an electromotive force is generated in a reception line 26 electromagnetically coupled to the transmission line 22 by a mutual induction action. . At this time, when the pachinko ball, which is a metal, approaches the detection unit 20a of the matrix sensor 20,
An eddy current is generated on the surface of the pachinko ball in a direction to cancel the magnetic flux generated by the matrix sensor 20. The impedance of the transmission line 22 changes due to the influence of the eddy current, thereby changing the current. In response, the reception line 26 changes the magnitude of the electromotive force.

At this time, each transmission line 22 and each reception line 2
6 is connected to the shield layer 69 via the insulating layer 68.
Therefore, the magnetic force does not wrap around each transmission line 22 and each reception line 26, and the detection accuracy is improved. On the receiving side, the receiving circuit 50 synchronizes with the transmitting circuit 40 by the sequence control circuit 47 and
1 to receive a signal from each reception line 26. As shown in FIG. 14, currents that are electromagnetic characteristic values appearing on the plurality of reception lines 26 are amplified ten times by the CT transformer 51. Since amplification is performed by the CT transformer 51, it is not necessary to increase the amplification of the amplifier on the receiving side. The CT transformer 51 insulates each of the receiving lines 26 of the matrix sensor 20 constituting the metal sensor from the analog multiplexer 52 of the receiving circuit 50 to prevent noise from entering the receiving circuit 50 from the pachinko game machine 10 and to perform reception.

The signal from the analog multiplexer 52 is amplified 100 times by the amplifier 53 (FIG. 17).
See step 92).

Waveform shaping is performed by the full-wave rectifier / amplifier 73. The signal from the full-wave rectifier / amplifier 73 is supplied to a low-pass filter 7.
At 4a and 74b, averaging is performed by integration processing.

Next, the received signal is supplied to the A / D converter 75
Sent to The A / D converter 75 converts a signal from the matrix sensor 20 into a digital signal in a predetermined bit unit such as 12 bits, and controls the sequence control circuit 63 to record the detection data in the bidirectional RAM 76 (step in FIG. 17). 93). This processing speed is as high as 25,000 times per second. Bidirectional RAM 7
6 is C by a write signal from the sequence control circuit 63.
After recording the detection data irrespective of the operation of the PU unit 30, the address is increased by inputting one clock.
Increase by 1 (see step 94 in FIG. 17). Two-way RA
The capacity of M76 is, for example, 2048 bytes. Next, the analog multiplexer 52 of the receiving circuit 50 switches the signal from each receiving line 26 (see step 95 in FIG. 17), and repeats the above steps 32 times according to the 32 receiving lines 26 (step 96 in FIG. 17). reference). After repeating 32 times, the analog multiplexer 44 of the transmission circuit 40
Switches the transmission line 22 (see step 97 in FIG. 17), and repeats the signal processing again.

Thus, the reception line 26 whose reception signal has changed is
., Transmitted at that time are detected by scanning, and the position of the pachinko ball in the matrix sensor 20 can be grasped as coordinates from the intersection. The number of the detection units 20a is 32 for the transmission line 22.
Since the total number of rows and reception lines 26 is 1024 in 32 columns,
Even if the pachinko ball passes through any of the safe holes 14a and the out holes 15 of the board 11, it can be detected.

The bidirectional RAM 76 determines the position of the pachinko ball in the matrix sensor 20 from the intersection of the reception line 26 where the reception signal has changed and the transmission line 22 transmitted at that time based on the signal from the reception circuit 50. It is stored as detection data of the detection unit 20a by each transmission line 22 and each reception line 26.

The CPU units 30 of the matrix controllers 80a and 80b read the detection data relating to the position of the pachinko balls recorded in the bidirectional RAM 76 by a read start signal as required, and perform arithmetic processing. The detection data of the pachinko ball based on the detection signal from the vertex detection means 81 is made to correspond to the ball monitoring area data from the ball monitoring area storage means 83 of the card 173, the number of matching detection data is counted, and stored as ball data. I do.

CPU unit 30 repeats this process. The matrix sensor 20 can follow the movement of the pachinko ball on the board 11 of the pachinko game machine 10 as a change in coordinates. Terminal management device 100
