The monitoring area data of the card 173 is read, and the detection data of the bidirectional RAM 76 is also read, and the detection data is made to correspond to the monitoring area data of the pachinko balls to monitor the pachinko balls.

This is means for reading the entrance side monitoring area data and the exiting side monitoring area data, and storing the detection data in the bidirectional RAM 76 as the number of balls hit when the detection data in the bidirectional RAM 76 is detected in the order of the entrance side detection data and the exit side detection data.

This is a means of subtracting the number of safe balls stored in d and storing the number of balls as the number of accessory balls.

Next, the effect will be explained.

Address signals and control signals from the CPU unit 30 are transmitted to the matrix sensor 20 via the CPU connector 46.

On the transmission side of the matrix sensor 20, 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.

Further, 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 the induction effect. 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, causing the current to change, and the magnitude of the electromotive force in the reception line 26 changes 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 sequentially outputs 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 is amplified and detected through a receiving connector 55, an amplifier 71, and a bandpass filter 72.

The received signal from the bandpass filter 72 is an analog signal, and this analog signal undergoes waveform shaping in the aftereffect rectifier/amplifier 73. The signal from the aftermath rectifier/amplifier 73 is averaged by integration processing in 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 2° into a digital signal in units of predetermined bits, such as 12 bits, and records the detected data in the bidirectional RAM 76 under the control of the sequence control circuit 63 (16th
(See step 93 in the figure). This processing speed is 25,000 times per second. After the bidirectional RAM 76 records the detection data regardless of the operation of the CPU unit 30 by the write signal from the sequence control circuit 63, the address is increased by +1 by inputting one clock (step 94 in FIG. 16). reference). 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 reception line 26 where the reception signal has changed and the transmission 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 hit ball monitoring areas 35a and 35b specified by the hit ball monitoring area specifying means 173a are located within the pachinko ball hitting path 11a on the board surface 11 along the guide rail 12,
The number of balls hit from the driving path 11a to the upstream side of the board surface 11 is stored in the hit ball counting means 30a only when the area data 35a and the area data 35b are detected in this order.

Pachinko balls that are hit with weak force and return again along the guide rail 12 without being hit upstream of the board 11 will be hit either in the order of area data 35a or area data 35a and area data 35a. It will return, but at this time it will not be counted as the number of balls hit, and the area data 35a, area data 35b, area data 35a, or area data 35a, area data 35b
- When the ball returns in either of the order of area data 35b and area data 35a, the number of balls hit can be accurately measured by subtracting the number of -degrees counted. Note that the position near the exit of the driving path 11a may be not only a position within the driving path 11a but also a position upstream of the board surface 11 exiting the driving path 11a.

After the pachinko ball detection data based on the signal from the receiving circuit 50 matches the entry side monitoring area data 35a of the hitting ball monitoring area specifying unit 173a, the returned ball subtraction means 30b
The number of balls that match the exit road side monitoring area data 35b within a predetermined period is subtracted from the counted number of the hit ball counting means 30a. For this reason, the number of pachinko balls that are once driven into the upstream of the board surface 11 from the exit of the driving path 11a, bounce off the nails 13 on the board surface 11, enter the driving path 11a, and are hit again, and the pachinko ball is It is possible to determine the exact number of balls hit by pachinko balls introduced from outside the game machine IO.

The out ball monitoring area 36 specified by the out ball monitoring area specifying means 173b corresponds to a predetermined line that partitions the board surface 11 between the most downstream safe hole 14a of the plurality of safe holes 14a and the out hole 15. , out ball monitoring area 3
The number of out balls passing through 6 and entering the out hole is stored in the out ball counting means 30c. Since the out ball monitoring area 36 is located away from the out hole 15, even if the number of balls hit is large and accumulates near the out hole 15, it is taken into consideration so as not to affect the measurement of the number of out balls. ing. Therefore, the number of out balls can be accurately measured.

The safe ball monitoring area 37 specified by the safe ball monitoring area specifying means 173C corresponds to the position of each safe hole 14a, and the number of safe balls that will enter each safe hole 14a is stored in the safe ball counting means 30d. The Rukoto. The number of balls entering the winning accessory device 14b may be set in the same manner, but may also be determined indirectly as shown below.

The accessory ball counting means 30e calculates the number of out balls stored in the out ball counting means 30c and the number of safe balls stored in each safe ball counting means 30d from the number of balls hit stored in the hit ball counting means 30a. It is subtracted and stored as the number of accessory balls that entered the winning accessory device 14b. Normally, the winning accessory device 14b has a metal member that is detected by the matrix sensor 20, and there are a wide variety of types. device 14
The number of accessory balls in b is directly determined by the matrix sensor 20.
Difficult to measure. Therefore, by subtracting the number of out balls and the number of safe balls that have entered the safe holes 14a at all locations from the number of balls hit, the number of accessory balls can be determined accurately and easily.

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 10, 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 stopping and check for abnormalities due to fraud. It can be used as data for nail adjustment, etc.

When monitoring the status of pachinko balls in a new model of pachinko game machine 10, the card 173 may be replaced accordingly. The card 173 can easily set monitoring data by simply inserting it into the interface section 176 of the data processing device, and the monitoring data can also be used when replacing pachinko game machines and applying it to various types of pachinko game machines. It is easy to change. Card 173 is
If the same model of pachinko game machine 10 is used, one cart can be copied and manufactured.

When performing more complicated processing, the cart 173 can handle the more complicated processing by freely selecting a CPU unit with a data processing speed corresponding to the processing. As the card 173, a RAM cart, mask RPM, EPROM, one-shot ROM, etc. can be used.

Note that the scanning speed of pachinko balls is not affected by the CPU because the scanning does not involve the CPU.

When replacing or installing the inner glass body 17 provided with the matrix sensor 20, the transmission connector 67a and the reception connector 6
7b is removable, and the inner glass body 17 can be easily removed from the transmitting circuit 40 and receiving circuit 50 of the mounting frame. Therefore, it is easy to replace a malfunctioning matrix sensor 20, and the matrix sensor 20 is mounted. It is also possible to easily attach the matrix sensor 20 to a pachinko game machine that does not have one.

In addition, the case where the hit ball monitoring area has two monitoring areas, the entrance side monitoring area and the exit side monitoring area, has been described.
There may be one monitoring area.

Moreover, the hit ball monitoring area may have three or more monitoring areas.

"Effects of the Invention" According to the pachinko game machine according to the present invention, since the pachinko balls are detected using the matrix sensor along the board surface, it is possible to detect hit balls, out balls, prize balls of the prize winning accessory device, etc. It is possible to detect pachinko balls on the surface of the board, it is possible to detect pachinko balls without physical contact, and it is durable.
