In the matrix sensor, when a signal of a predetermined frequency is sequentially transmitted from the transmission circuit to a plurality of folded transmission lines to generate a magnetic field, a mutual induction action is exerted on the reception line electromagnetically coupled to the transmission line. An electromotive force is generated and the receiving circuit receives the signal from the receiving line.

When a signal of a predetermined frequency is sequentially transmitted from a plurality of folded transmission lines 22 to generate a magnetic field, an electromotive force is generated in the reception line 26 electromagnetically coupled to the transmission lines 22 by mutual induction. .. At this time, when the metal pachinko ball approaches the detection unit 20a of the matrix sensor 20,
On the surface of the pachinko ball, an eddy current is generated in the direction in which the magnetic flux from the matrix sensor 20 is canceled. The impedance of the transmission line 22 changes due to the influence of the eddy current and changes the current, and accordingly, the reception line 26 changes the magnitude of the electromotive force.

On the receiving side, the receiving circuit 50 receives a signal from each receiving line 26 via each CT transformer 51 in synchronization with the transmitting circuit 40 by the sequence control circuit 47. As shown in FIG. 14, the current that is an electromagnetic characteristic value that appears in the plurality of reception lines 26 is amplified by the CT transformer 51 ten times.

The analog multiplexer 52 switches the signal from each receiving line 26 passing through the CT transformer 51 by the channel switching logic 54 and sequentially outputs it at a predetermined cycle. The signal from the analog multiplexer 52 is amplified 100 times by the amplifier 53 (FIG. 16).
See step 92).

The received signal is received by the receiving connector 55 and the amplifier 7.
1. Amplification and detection are performed through the bandpass filter 72. The received signal from the bandpass filter 72 is an analog signal, and this analog signal is
The full-wave rectification / amplifier 73 performs waveform shaping. The signal from the full-wave rectifier / amplifier 73 is supplied to the low-pass filter 7
Averaging is performed by integration processing at 4a and 74b.

Next, the received signal is the A / D converter 75.
Sent to. The A / D converter 75 converts the 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. 16). 93).

This processing speed is as high as 25,000 times per second. The bidirectional RAM 76 records the detection data irrespective of the operation of the CPU unit 30 by the write signal from the sequence control circuit 63, and then inputs 1 clock to increment the address by 1 (see step 94 in FIG. 16). .. The capacity of the bidirectional RAM 76 is, for example, 2048 bytes.

Next, the analog multiplexer 52 of the receiving circuit 50 switches the signal from each receiving line 26 (see FIG. 16).
32 according to 32 reception lines 26 (see step 95)
The above steps are repeated once (see step 96 in FIG. 16). After repeating 32 times, the analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97 in FIG. 16), and repeats the signal processing again.

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

The bidirectional RAM 76 determines the position of the pachinko ball in the matrix sensor 20 from the intersection position of the reception line 26 in which 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 unit 30 reads the detection data relating to the position of the pachinko ball recorded in the bidirectional RAM 76 by a read start signal as necessary, performs arithmetic processing, and stores the detection data in the card 63. The pachinko balls are monitored in association with the monitoring data.

The abnormality judging means 30a outputs an alarm signal when the received signal of the receiving circuit 50 is out of the normal detection range of the matrix sensor 20 stored in the normal range storage means 63a, and the occurrence of the abnormality is externalized in real time. Let me know. The alarm signal notifies the outside of the occurrence of an abnormality by an alarm sound or blinking display by an alarm device, a screen display by a monitoring CRT, or the like. As a result, even if the monitor does not always monitor the detection result, it is possible to immediately deal with the failure or abnormality.

For example, the received signal is in the normal range storage means 63.
Nail 11b, 11b ..., which is stored in a, winning prize device device 14
When it comes out of the fixed detection range by the detection of the fixing metal fitting such as b, it can be known whether the mounting frame 21 is open or closed by the mounting frame opening signal from the abnormality determining means 30a.

When the received signal is out of the normal range for detecting the number of pachinko balls stored in the normal range storage means 63a, the external abnormality signal from the abnormality determination means 30a causes
It is possible to know the occurrence of abnormalities due to external magnets or external noise.

When the received signal is out of the signal voltage range of the received signal stored in the normal range storage means 63a, a failure signal from the abnormality determination means 30a may cause a failure such as disconnection or short circuit of the matrix sensor or circuit failure. I can know.

When the received signal is out of the normal movement detection range of the pachinko balls stored in the normal range storage means 63a, the pachinko balls are stopped by being caught on the game board by the ball stop signal from the abnormality judging means 30a. Can know that.

The CPU unit 30 repeats this process. In this way, the matrix sensor 20 can follow the movement of a pachinko ball on the game board surface 11 of the pachinko game machine 10 as a change in coordinates, such as the incoming state of the pachinko ball. In the pachinko game machine 10, by monitoring the progress of the game by the matrix sensor 20 and knowing the status of the hit ball, the out ball, and the safe ball of the winning prize device device 14b, stop hit management and abnormality check due to fraud, It can be used as data such as nail adjustment.

The inner glass body 17 is formed by quadruple lamination of an inner protective glass plate 17a, a receiving glass base substrate 17b, a transmitting glass base substrate 17c, and an outer glass plate 17d, and also a receiving glass base substrate. 17b
Alternatively, the transmission-side glass base substrate 17c may be formed of one sheet to form a triple-layered structure.
