The bidirectional RAM 76 is a memory that stores the position of the pachinko ball as detection data of the detection unit 20a by each transmission line 22 and each reception line 26 based on the signal from the reception circuit 50, and has an internal counter. All processing of pachinko ball matrix data is performed by the counter. Further, the CPU memory control board 172 includes a power supply unit 77.

The CPU unit 30 reads the monitoring side area data of the card 173, reads the detection data of the bidirectional RAM 76, and monitors the pachinko balls by associating the detection data with the monitoring area data of the pachinko balls.

Next, the effect will be explained.

Address signals and control signals from the CPU unit 30 are transmitted to the pachinko game machine 10 via the CPU connector 46.

In the pachinko game machine 10, on the transmission side, the sequence control circuit 47 receives the start signal, divides the 16 MHz original clock as necessary, and outputs a transmission clock. The transmission clock from the sequence control circuit 47 is waveform-shaped from a digital signal to an analog signal by a bandpass filter 48, and then amplified by an amplifier 49.
It is sent to the transmission connector 41.

Furthermore, the transmission signal is amplified by an amplifier 42 in the transmission circuit 40. The analog multiplexer 44 is a channel switched by the channel switching logic 43,
The totem pole driver 45 is operated in sequence, so that the totem pole driver 45 sequentially outputs the signal amplified by the amplifier 42 to the transmission line 22 at a predetermined period (see step 91 in FIG. 16).

In the matrix sensor 20, when a magnetic field is generated by sequentially transmitting signals of a predetermined frequency from the transmission circuit 40 to the plurality of folded transmission lines 22, the reception lines 26 electromagnetically coupled to the transmission lines 22 are mutually connected. An electromotive force is generated due to induction. At this time, when a pachinko ball made of 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 that cancels out 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, and the receiving line 26 changes the magnitude of the electromotive force accordingly.

On the receiving side, the receiving circuit 50 includes a sequence control circuit 47
It synchronizes with the transmitting circuit 40 and receives signals from each receiving line 26 via each CT sensor 51. As shown in FIG. 14, the current, which is an electromagnetic characteristic value, flowing through the plurality of reception lines 26 is amplified ten times by the CT sensor 51. CT
Since amplification is performed by the sensor 51, there is no need to increase the amplification degree of the amplifier on the receiving side. The CT sensor 51 is a matrix sensor 20 that constitutes a metal sensor.
Each receiving line 26 and the analog multiplexer 52 of the receiving circuit 50 are insulated to prevent noise from entering the receiving circuit 50 from the pachinko game machine 10 and to amplify the received signal.

The analog multiplexer 52 transfers the signals from each receiving line 26 that have passed through the CT sensor 51 to the channel switching logic 5.
4, and outputs sequentially at a predetermined period. The signal from the analog multiplexer 52 is sent to the amplifier 5
3, it is amplified 100 times (step 92 in Figure 16).
reference).

The received signal passes through the receiving connector 55, the amplifier 71, and the bandpass filter 72, where it is amplified and detected.

The received signal from the bandpass filter 72 is an analog signal, and this analog signal is subjected to waveform shaping in the aftereffect rectifier/amplifier 73. The signal from the aftermath rectifier/amplifier 73 is averaged by integration processing through low-pass filters 74a and 74b.

The received signal is then sent to A/D converter 75.

The A/D converter 75 converts the signal from the matrix sensor 20 into a digital signal in units of predetermined bits, such as 12 bits, and records the detected data in the bidirectional RAM 7B under the control of the sequence control circuit 63 (16th
(See step 11 step 93). This processing speed is 25,000 times per second. The bidirectional RAM 76 records the detected data by the write signal from the sequence control circuit 63 regardless of the operation of the CPU unit 30, and then
The address is increased by +1 by inputting the 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
Switching the signals from each receiving line 26 (Step 9 in Fig. 16)
5), and the above steps are repeated 32 times according to the 32 trees of reception lines 26 (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 the signal processing is repeated again.

In this way, the receiving line 26 where the received signal has changed and the transmitting lines 22, 22, etc. that were transmitted at that time are detected by scanning, and the position of the pachinko ball on the matrix sensor 20 is determined as coordinates from the intersection position. be able to. Since the number of detection units 20a is 1024 in total, with 32 rows of transmitting lines 22 and 32 columns of receiving lines 26, it is possible to detect pachinko balls no matter which safe hole 14a and out hole 15 on the board 11 they pass through. can.

Based on the signal from the receiving circuit 50, the bidirectional RAM 76 calculates the position of the pachinko ball on each transmission line by the matrix sensor 20 from the intersection position of the reception line 26 where the received signal has changed and the transmission line 22 that was transmitted at that time. 22 and each receiving line 26 is stored as detection data of the detection unit 20a.

The CPU unit 30 reads the detection data regarding the position of the pachinko balls recorded in the bidirectional RAM 76 according to the read start signal as necessary, performs arithmetic processing, and combines the detection data with the pachinko ball monitoring data stored in the card 173. Monitor the pachinko balls accordingly.

The CPU unit 30 repeats this process. The matrix sensor 20 can track the movement of pachinko balls, such as the landing status of pachinko balls on the board 11 of the pachinko game machine IO, as changes 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 hit balls, out balls, and safe balls of the winning accessory device 14b, it is possible to manage the winnings and check for abnormalities due to fraud. It can also be used as data for nail adjustment, etc.

When monitoring the status of pachinko balls in a new model pachinko game machine 10, the cart 173 may be replaced accordingly. By inserting the cart 173 into the interface unit 176 of the data processing device, monitoring data can be easily set, and the monitoring data can be easily set when the cart 173 is applied to various types of pachinko game machines, such as replacing pachinko game machines. Data can be easily changed. Card 173 is
If the same model of pachinko game machine IO is used, one card can be copied and manufactured. When performing more complicated processing, the card 173 can handle the more complicated processing by freely selecting a CPU unit with a data processing speed corresponding to the processing.

Note that if the ball detection algorithm is simple, an inexpensive 8-bit CPU is sufficient for the CPU unit 30; if a complicated algorithm is required, a high-speed processing is required. It is best to select one that uses a 16-bit CPU. In either case, the scanning speed of the pachinko ball is determined by the scanning speed
Since it does not go through U, it is not affected by the CPU.

In addition, the matrix [10 transmitting/receiving board 171, which includes several transmitting circuits 40 and receiving circuits 50, is attached to the lower end 38a of the mounting frame 38, and does not block the board 11 of the pachinko game machine 10, so that it does not feel strange when playing the game. few.
