By the way, the pachinko game machine 10 generates noise of various frequencies depending on the model. If the frequency of this noise matches or approaches the transmission frequency to the detection matrix 20, the detection accuracy of pachinko balls will be significantly deteriorated. In order to eliminate the influence of this noise, for example, depending on the model of the pachinko game machine 10, several types of pachinko ball detection devices having a transmission frequency that does not match or approach the noise frequency in the frequency band of 1 to 1.3 MHz are used.

I have.

 Next, the operation will be described.

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

In the pachinko game machine 10, on the transmission side, the sequence control circuit 47 receives the start signal, divides the frequency of the 16 MHz original clock as necessary, and outputs the transmission clock. 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, and then amplified by an amplifier 49.
Sent to.

Further, the transmission signal is amplified by the amplifier 42 in the transmission circuit 40. The analog multiplexer 44 sequentially operates the totem pole driver 45 on the channel switched by the channel switching logic 43, whereby the totem pole driver 45 sequentially transmits the signal amplified by the amplifier 42 to the transmission line 22 at a predetermined cycle. Output (No. 14
On the receiving side, as shown in FIG. 13, on the receiving side, a current as an electromagnetic characteristic value appearing on the plurality of receiving lines 26 is detected by the CT sensor 51 for 10 times.
It is amplified twice. Because amplification is performed by the CT sensor 51,
As a result, it is not necessary to increase the degree of amplification of the amplifier on the receiving side. The CT sensor 51 insulates each reception line 26 of the detection matrix 20 constituting the pachinko ball detection sensor from the analog multiplexer 52 of the reception line 50, and the pachinko game machine 10
To prevent noise from entering the receiving circuit 50 from
Amplify the received signal.

The CT sensor 51 can prevent noise and DC drift from occurring due to the CP amplifier itself as compared with the case where a CP amplifier is used, and can improve the detection accuracy of a received signal. CP amplifiers are generally large compared to CT sensors 51, and trying to obtain the same level of accuracy as CT sensors 51 with OP amplifiers would be expensive and complicated. I will. On the other hand, the CT sensor 51 is smaller and simpler in configuration than the OP amplifier,
By using the CT sensor 51, the matrix I / O transmission / reception board 71 and the pachinko ball detection device can be reduced in size. Note that the matrix I / O transmission / reception board 71 has a simple configuration mainly including the CT sensor 51, the analog multiplexer 52, and the amplifier 53, thereby reducing the size and reducing the number of lead lines.

The analog multiplexer 52 switches signals from the respective receiving lines 26 that have passed through the CT sensor 51 by the channel switching logic 54, and sequentially outputs the signals at a predetermined cycle. The signal from the analog multiplexer 52 is output by the amplifier 53 to 100
It is amplified twice (see step 92 in FIG. 14).

The reception signal is amplified and detected through a reception connector 55, an amplifier 71, and a band-pass filter 72. The received signal from the band-pass filter 72 is an analog signal in which several cycles constitute one scan, as shown in FIG. This analog signal is subjected to waveform shaping by a full-wave rectifier / amplifier 73 as shown in FIG. 15 (B).

The signal from the full-wave rectifier / amplifier 73 is averaged by an integration process as shown in FIG. 15 (C) by a low-pass filter 74a, and furthermore, the low-pass filter 74b
Then, as shown in FIG. 15D, averaging is performed. As a result, the noise is also averaged with the received signal,
The amount of noise is extremely small compared to the signal, and errors due to noise can be ignored. Low-pass filter 74a,
When averaging is performed by 74b, since the noise has already passed through the band-pass filter 72, there is no noise enough to cause an error. For this reason, the transmission frequency is selected to be a frequency that is not affected by the noise of the pachinko game machine 10, but the bandpass filter 72 includes:
The one suitable for the transmission frequency is used.

Next, the received signal is sent to A / D converter 75. A / D
The converter 75 converts a signal from the detection matrix 20 into a digital signal in a predetermined bit unit, for example, 12 bits,
The received data is recorded in the bidirectional RAM 76 under the control of the sequence control circuit 63 (see step 93 in FIG. 14).
This processing speed is as high as 25,000 times per second. The bidirectional RAM 76 records received data irrespective of the operation of the CPU unit 30 by a write signal from the sequence control circuit 63, and then inputs one clock to increase the address by +1 (see step 94 in FIG. 14). ). 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 step 95 in FIG. 14), and repeats the above steps 32 times according to the 32 receiving lines 26 (FIG. 14). See step 96). After 32 repetitions,
The analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97 in FIG. 14), and repeats the signal processing again.

Thus, based on the signal from the receiving circuit 50, the bidirectional RAM 76 determines the position of the pachinko ball in the detection matrix 20 from the intersection position between the receiving line 26 where the received signal has changed and the transmitting line 22 transmitted at that time. It is stored as coordinate data of the transmission line 22 and each reception line 26.

The RAM card 173 stores the monitoring data of the pachinko balls, and the CPU unit 30 performs the detection corresponding to the key points such as the safe holes 14a, 14a, and the out holes 15 recorded in the RAM card 173. The monitoring data at the positions of the units 20a, 20a ... is being read.

The CPU unit 30 reads the coordinate 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 process, and associates the coordinate data with the monitoring data of the pachinko ball to display the pachinko ball. Monitor. That is, the CPU unit 30 does not directly obtain the coordinate data from the receiving circuit 30, but once executes the bidirectional RA.
Read the coordinate data stored in M76.

CPU unit 30 repeats this process. Each circuit of the CPU memory control board 72 and the CPU unit 30 perform processing while ignoring each other's waiting time, so that the load on the CPU unit 30 is reduced and the processing speed of the CPU unit 30 can be increased. The CPU unit 30 tracks the movement of the pachinko ball on the board 11 of the pachinko game machine 10 as a change in coordinates and monitors the progress of the game. By knowing the situation of incoming balls, outgoing balls, and the like, it is possible to check for abnormalities due to hitting management and fraud, and use the data as nail adjustment data.

The RAM card 173 is used to monitor the state of pachinko ball arrival by the new pachinko game machine 10, and the RA
You just need to replace the M gate. The RAM card 173 can easily set monitoring data simply by being inserted into the interface unit 176 of the data processing device, and can be monitored even when it is applied to various types of pachinko game machines, such as replacing pachinko game machines. Data can be easily changed. RAM card 1
73 can be manufactured by copying one card as long as it is used for the pachinko game machine 10 of the same model. When performing more complicated processing, the RAM card 173 can cope with more complicated processing by freely selecting a CPU unit having a data processing speed corresponding to the processing.

If the algorithm of ball detection is a simple one, it is sufficient to use an inexpensive 8-bit CPU. If a complicated algorithm is required, the CPU unit 30 performs high-speed processing. It is better to select one that uses a 16-bit CPU. In any case, the scanning speed of the pachinko ball is not affected by the CPU because the scanning is not performed via the CPU.

As described above, when a signal of a predetermined frequency is sequentially transmitted from the transmission circuit 40 to the plurality of folded transmission lines 22 to generate a magnetic field, the reception line 26 electromagnetically coupled to the transmission line 22 includes:
An electromotive force is generated by the mutual induction action. At this time, when the pachinko ball, which is a metal, approaches the detection unit 20a of the detection matrix 20, an eddy current is generated on the surface of the pachinko ball in a direction to cancel the magnetic flux by the detection matrix 20. Transmission line 22
The impedance changes due to the influence of the eddy current to change the current, and accordingly, the reception line 26 changes the magnitude of the electromotive force.

The receiving circuit 50 is a transmitting circuit
In synchronization with 40, a signal is received from each reception line 26 via each CT sensor 51. .. Can be detected by scanning, and the position of the pachinko ball in the detection matrix 20 can be grasped as coordinates from the intersection position. Building units 20
The number of a is 32 lines for the transmission line 22 and 32 columns for the reception line 26, for a total of 1024
Since the pachinko balls are individual pieces,
And can also be detected through the out hole 15.

Since the voltage waveform to the transmission line 22 is a continuous sine wave centered on 0 V, there is no generation of noise such as a rectangular wave, and the influence on other devices such as the CPU unit 30 is prevented. Can be.

In addition, since the voltage waveform has a transmission frequency band of 1 to 1.3 MHz, noise from peripheral devices of the pachinko game machine 10 is not easily received, and the response sensitivity can be increased. Note that components that can process signals in the frequency band of 1 to 1.3 MHz are less expensive than components that process signals in the higher frequency band.

Further, the transparent conductive film on the surface of the outer glass plate 17d has a function of shielding electric influence of a metal or a dielectric substance from the outside and increasing a reaction sensitivity to a pachinko ball.

Note that the connection is made by using the weight of the inner glass body (front glass) 17 so that the transmission terminal 23 and the reception terminal 27 are placed on the lower side and connected to the transmission connector 67a and the reception connector 67b inside the lower part of the mounting frame. The connection can be performed simultaneously when the inner glass body 17 is mounted on the mounting frame.

For the replacement or attachment of the inner glass body 17 provided with the detection matrix 20, the transmitting connector 67a and the receiving connector 67b are detachable, and the inner glass body 17 can be easily removed from the transmitting circuit 40 and the receiving circuit 50 of the mounting frame. Therefore, the failed detection matrix 20 can be easily replaced, and the detection matrix 20 can be easily attached to a pachinko game machine without the detection matrix 20.

Further, since the folded portion 61 of the transmission line 22 and the reception line 26 is formed by a conductor pattern, the transmission line 22 and the reception line
The manufacture of the transmission line 22 and the reception line 26 is further facilitated since the manufacturing of the transmission line 22 and the reception line 26 is facilitated and the routing portion 64 of the transmission line 22 and the reception line 26 is formed by a conductor pattern.

 Next, the operation of the detection sensor for the player will be described.

As shown in FIG. 1, in the player detection sensor 80, the oscillation circuit 81 oscillates infrared rays for detecting a player, and the light emitter 83 is controlled by the light emission signal output control unit 82 so that the light emitting device 83 of the pachinko game machine 10 Transmits infrared light to the player's playing position. The infrared rays are reflected from the player and received by the light receiver 84 when the player is at the gaming position. The signal received by the light receiver 84 is amplified by the light receiving amplifier 85, and the received light discriminator 86 determines whether or not the transmitted infrared ray has been received. The light receiving discriminator 86 outputs a detection signal when it determines that the transmitted infrared light has been received. With this detection signal,
The player detection sensor 80 can detect the presence or absence of a player of the pachinko game machine 10.

The detection results are totaled by the detection signal of each pachinko game machine 10, and the presence or absence of a player at all the pachinko game machines 10 in the game hall can be accurately grasped.

Note that the player sensor 80 is connected to the matrix I / O unit 170
The pachinko game machine 10 facilitates installation of the player sensor 80.

Further, the player sensor 80 may be directly attached to the glass plate.

 Next, a second embodiment of the present invention will be described.

This embodiment is the same as the first embodiment, except that one of the transmitting unit and the receiving unit of the player detection sensor is provided in another portion or outside of the main body of the pachinko game machine. The same members as those described above are denoted by the same reference numerals, and redundant description will be omitted.

FIG. 17 shows a front view of an island 101 having the pachinko game machine 10 of the second embodiment. That is, a plurality of pachinko game machines 10 are provided on the front of the island 101, and each of the pachinko game machines 10 has a mounting frame 10a as in the first embodiment.
Has a matrix I / O unit 170 below.

Inside the case of the matrix I / O unit 170, of the player detection sensor 180, the light receiver 84, the light receiving amplifier 85,
The light receiving discriminator 86 is housed therein, and the presence or absence of a customer can be determined by detecting the human body temperature. In this case,
By detecting even a change in body temperature, it can be determined whether the next customer is the same person. Further, if the color is detected at the same time, more accurate identification can be performed.

In this embodiment, since only the light receiver 184 is housed inside the case of the matrix I / O unit 170, the matrix I / O
The size of the unit 170 can be reduced.

In the second embodiment, a light emitting unit is provided in the matrix I / O unit instead of the light receiving unit,
A light receiving unit may be provided at the position of the light emitting unit.

In each embodiment, the presence or absence of a player is detected by transmitting infrared rays from the light emitting device to the light receiving device. However, the light emitting device and the light receiving device are different from each other in order to detect the player. A transmitting unit or a receiving unit that transmits a sound wave such as an electromagnetic wave or an ultrasonic wave may be used.

According to the pachinko game machine of the present invention, since the RAM card is removably inserted into the interface unit and the pachinko ball monitoring data is stored in a readable manner, the monitoring data can be set or changed. This can be easily performed, and an appropriate ball entry state can be obtained.
