In a matrix sensor, when a signal of a predetermined frequency is sequentially transmitted from a transmission circuit to a plurality of folded transmission lines to generate a magnetic field, a reception line electromagnetically coupled to the transmission line is subjected to mutual induction. An electromotive force is generated, and the receiving circuit receives a signal from the receiving line. At this time, when a metal such as a pachinko ball approaches the matrix sensor, an eddy current is generated on the surface of the metal in a direction to cancel the magnetic flux by the matrix sensor.

In response, the reception line changes the magnitude of the electromotive force. The transmission line and the reception line having changed electromagnetic characteristics are detected, and the position of the metal on the matrix sensor can be grasped as coordinates from the intersection position.

The abnormality determining means outputs an alarm signal when the received signal of the receiving circuit is out of the normal detection range of the matrix sensor stored in the normal range storage means.

See step 92).

The received signal is transmitted to the receiving connector 55 and the amplifier 7
1. Amplification and detection are performed via the band-pass filter 72. The received signal from the bandpass filter 72 is an analog signal, and this analog signal is
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 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).

The 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 increases the address by +1 by inputting one clock (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 (FIG. 16).
(Refer to step 95), 32 according to the 32 reception lines 26
The above steps are repeated once (see step 96 in FIG. 16). After 32 repetitions, 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 whose reception signal has changed
., 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 game 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 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 an arithmetic processing, and converts the detection data into the pachinko ball stored in the card 63. The pachinko balls are monitored in correspondence 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 detects occurrence of abnormality in real time. Inform 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. Thus, even if the monitoring person does not constantly monitor the detection result, it is possible to immediately respond to a failure or abnormality.

For example, the received signal is stored in the normal range storage unit 63.
.., the winning character device 14
When it is out of the fixed detection range by the detection of the fixing bracket such as b, it is possible to know 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 pachinko ball detection range 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 and 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, the failure signal from the abnormality determination means 30a determines that a failure such as disconnection, short circuit or circuit abnormality of the matrix sensor has occurred. You can know.

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

CPU unit 30 repeats this process. In this way, the matrix sensor 20 can follow the movement of the pachinko ball on the game board surface 11 of the pachinko game machine 10 as a change in coordinates. In the pachinko game machine 10, the progress of the game is monitored by the matrix sensor 20, and by knowing the status of the hit ball, the out ball, and the safe ball of the winning character device 14b, it is possible to control the hitting and check for abnormalities due to fraud, It can be used as data for nail adjustment and the like.

The inner glass body 17 is composed of a four-layer structure 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. 17b
In addition, the transmission-side glass base substrate 17c may be configured as a single sheet to form a three-layer structure.
