Description Game machine using a metal body as a vehicle [Technical field]

The present invention relates to a game machine that signals a game using a metal body as an intermediary, and in particular, moves a metal body in a space sandwiched between parallel planes so that the metal body enters a specific hole. A game machine that can be a hit.

[Background technology]

For a game machine that uses a metal object as a vehicle, a metal object, for example, a metal ball is moved in a specific space set in the game device, and a prize is determined according to the destination. As a typical example, there is a pachinko game machine in which a pachinko ball made of a metal ball is dropped and moved in a space sandwiched between parallel planes having many obstacles.

This pachinko game machine has a board constituting a space for moving the pachinko balls, a glass plate covering the pachinko balls at regular intervals, and a projection mechanism for projecting the pachinko balls onto an upper portion of the board. Pachinko game machines are installed so that their board surfaces are substantially parallel to the vertical direction. On the board, a number of safe holes and pachinko balls that did not enter the safe hole are the most hit when a pachinko ball enters and is ejected from the board. One art hole that finally gathers and is discharged from the panel is provided.

In addition, a large number of pins (nails) are used as obstacles on the board, which often collide with pachinko balls falling along the board surface and cause fluctuations in the direction of movement. Now, protruding from the board, they are mounted substantially vertically-these pins give the impinging pachinko ball a wobble in the direction of its movement and, in some cases, a safe hole The distribution is determined and arranged on the board so as to guide the vehicle toward the center, and in some cases, to guide the vehicle out of the safe hole.

Due to such a structure, pachinko game machines, such as machines that are easy to hit and machines that are difficult to hit, are slightly different in pin arrangement and inclination of each pin. , Individuality arises in the machine. In the same machine, there are differences between safe holes with high hit rates and safe holes with low hit rates. Moreover, this difference also varies depending on the machine.

In a game center where many game machines of this type are installed, it is important to know the individuality of each game machine in terms of profit management of the game center and customer management. For example, if there are too many machines with hits, the game center will be damaged, while if the machines are difficult to hit, customers will lose interest and are not favorable for business. Therefore, it is necessary to take measures by knowing the individuality of each game machine installed in the center. For such a purpose, in pachinko game machines, Detecting the path through which the ball passes. As a sensor used for this purpose, for example, Japanese Patent Publication No. 6-35060 discloses a sensor provided with an upper sheet and a lower sheet constituting a contact pair. I have. According to this technique, when a pachinko ball is placed on the upper sheet and pressed, the contact pair comes into contact with each other and the presence of the pinching ball is detected.

However, since this conventional sensor has a pair of contacts, the arrangement of the sheets is restricted, and the sensor can only be arranged along the flow path of the pachinko balls. Therefore, it is not possible to detect the movement of the ball from the viewpoint of viewing the entire board. For this reason, for example, there is a problem that it is difficult to detect how and when the ball enters the safe hole and the gate hole.

In addition, since the detection is performed by the physical contact of the contact pair, depending on the motion state of the ball, the pressure on the sheet is weak, and the contact pair does not contact and may not be detected. obtain. In addition, poor contact may occur due to wear, corrosion, etc. of the contact pair. Further, erroneous contact of the contact pair may occur due to vibration or the like or due to chattering. For this reason, there is a problem of lack of reliability.

Furthermore, since the pressing force of the ball is used, there is a problem that the movement of the ball is slightly affected.

Such problems can occur not only in pachinko game machines. Therefore, it is desirable to take some measures. On the other hand, when the sensors are arranged along the board surface, the part for detecting the metal body and the signal processing unit for driving the metal body have an adverse effect on the game area, for example, an influence such as narrowing the game area and obstructing the visual field. The problem is how to accommodate the space in a limited space without providing the space. This has not been considered before.

The analog multiplexer 52 sequentially receives signals from the respective CTs 51, and the amplifier 53 amplifies the signal from the analog multiplexer 52. The channel switching logic 54 is the same as the channel switching logic 43 of the transmission circuit 40.

As shown in Fig. 15, the CPU memory control board 17 2 has a CPU connector connected to the controller 30 on the transmitting side. Receiving the transmission clock, a sequence control circuit 47 for transmitting a transmission clock in accordance with a start signal from the control device 30 via the CPU connector 46, and receiving the transmission clock. It has a bandpass filter 48 for transmitting a transmission signal, and an amplifier 49 for amplifying the transmission signal and transmitting the amplified signal to the transmission connector.

On the receiving side, the CPU memory control board 172 includes an amplifier 71 for amplifying a signal received from the receiving connector 55, a bandpass filter 72 for receiving the amplified signal, and a bandpass filter. A full-wave rectifier / amplifier 73 that receives the received signal from the filter 2 and a two-stage mouthpiece that receives the received signal from the full-wave rectifier / amplifier 73 Filters 74a and 74b, and one mouth. An AZD converter 75 that receives a received signal from the filter 74 b and sends digital data under the control of the sequence control circuit 47 to the bidirectional RAM 76, receives the digital data, and receives the digital data. 7 to write received data, and transmit the received data to the control device 30 via the CPU connector 46 in response to the read signal from the CPU connector 46. Have.

The bidirectional RAM 76 stores the position of the metal body as detection data of the detection unit 20a by each transmission line 22 and each reception line 26 based on a signal from the reception circuit 50. Memory. The bidirectional RAM 76 has a counter inside, and all processing of metal matrix data is performed by the counter. Contro Lonor Board 1 72 has a power supply unit 77.

The controller 30 reads the monitoring area data of the card 173, reads the bidirectional RAM76 detection data, and monitors the metal object by associating the detection data with the monitoring area data of the metal object. It is supposed to.

Next, the operation will be described.

The address signal and the control signal from the control device 30 are transmitted to the game machine 10 via the CPU connector 46. In the game machine 10, the sequence control circuit 47 on the transmission side starts. Receiving the clock signal, generates a transmission clock by dividing the 16 MHz original clock as necessary, and outputs this. The transmission clock from the sequence control circuit 47 is waveform-shaped from a re-digital signal to an analog signal by a non-pass filter 48, then amplified by an amplifier 49, and then transmitted. Sent to 1.

Further, in the case of a transmission signal, the analog multiplexer 44 amplified by the amplifier 42 in the transmission circuit 40 is _a channel switched by the channel switching logic 43 and a totem pole driver. 4 are operated sequentially, whereby the re-temp pole driver 45 sequentially outputs the signal amplified by the amplifier 42 to the transmission line 22 at a predetermined period (see FIG. 16). See page 91).

In the matrix sensor 20, a plurality of folds are transmitted from the transmission circuit 40. When a signal of a predetermined frequency is sequentially transmitted to the return transmission line 22 to generate a magnetic field, an electromotive force is generated in the reception line 26 electromagnetically coupled to the transmission line 22 by mutual induction. appear. At this time, when the metal body, which is a metal, approaches the detection unit 20a of the matrix sensor 20, the surface of the metal body is swirled in a direction to cancel the magnetic flux by the matrix sensor 20. An electric current is generated. For this reason, the magnitude of the induced current in the sparsely located receiving line 26 becomes smaller due to the eddy current.

On the receiving side, the receiving circuit 50 synchronizes with the transmitting circuit 40 by the sequence control circuit 47 and receives a signal from each receiving line 26 via each CT sensor 51. As shown in FIG. 14, the induced current appearing on the plurality of receiving lines 26 is amplified 10 times by the CT sensor 51. Since amplification is performed by the CT sensor 51, it is not necessary to increase the amplification degree of the amplifier on the receiving side. The CT sensor 51 insulates the receiving lines 26 of the matrix sensor 20 constituting the metal sensor from the analog multiplexer 52 of the receiving circuit 50, and separates the receiving circuit 50 from the game machine 10. It prevents noise from entering the receiver and amplifies the received signal.

The analog multiplexer 52 switches signals from the respective receiving lines 26 via the CT sensor 51 by the channel switching logic 54 and sequentially outputs the signals in a predetermined frequency. The signal from the analog multiplexer 52 is amplified 100 times by the amplifier 53 (see step 92 in FIG. 16). The received signal passes through a receiving connector 55, an amplifier 71, and a bandpass filter 72, and is amplified and detected. The received signal from the band-pass filter 72 becomes an analog signal, and the analog signal is subjected to waveform shaping by the full-wave rectifier / amplifier 73. The signal from the full-wave rectifier 7amplifier 73 is averaged by edge processing in the low-pass ﬁ lters 74a and 74b.

Next, the received signal is sent to the AZD converter 75. The AD converter 75 converts a signal from the matrix sensor 20 into a digital signal in a predetermined bit unit, for example, 12 bits, and is controlled by the sequence control circuit 63 to detect data. Record on the bi-directional RAM 76 (see step 93 in Fig. 16). This processing speed is 25,000 times per second. The bi-directional RAM 76 records the detection data in response to the write signal from the sequence control circuit 63, regardless of the operation of the control device 30, and then inputs one clock. Raise the rear dress +1 (see step 94 in Fig. 16). The capacity of the bidirectional RAM 76 is, for example, 248 bytes.

Next, the analog multiplexer 52 of the receiving circuit 50 switches the signal from each receiving line 26 (see step 95 in FIG. 16), and according to the two receiving lines 26, Repeat the steps 32 times (see step 96 in Fig. 16). 3 If this is repeated twice, the analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97 in Fig. 16), and again, the signal processing Is repeated.

In this way, the receiving line 26 whose received signal has changed and the transmitting lines 22, 22,... Transmitted at that time are detected by scanning, and the matrix sensor is detected from the intersection position. The position of the metal body at 20 can be grasped as coordinates. Since the number of detection units 20a is 32 for the transmission line 22 and 32 for the reception line 26, there are a total of 10 2 4 pieces. It can be detected even after passing through a and the hole 15. Based on the signal from the receiving circuit 50, the bidirectional RAM 76 determines the matrix sensor 20 from the intersection of the receiving line 26 where the receiving signal has changed and the transmitting line 22 that transmitted at that time. The position of the metal body at the time is stored as detection data of the detection unit 20a by each transmission line 22 and each reception line 26.

The control device 30 reads the detection data on the position of the metal object recorded in the bidirectional RAM 76 by the read start signal as necessary, performs an arithmetic operation, and stores the detection data in the card. Monitor the metal object in correspondence with the monitoring data of the metal object stored in 173.

Control device 30 repeats this process. The matrix sensor 20 can follow the movement, such as the insertion state of a metal object on the board 11 of the game machine 10, as a change in coordinates. In the game machine 10, the progress of the game can be monitored by detecting the movement trajectory of the metal object put on the board by the matrix sensor 20. For example, detecting an abnormal trajectory of a metal object Anyway, it can detect fraud. As cheating, for example, the direction of movement of a metal body is intentionally bent by a magnet or the like from the outside. In addition, by counting the number of metal objects entering the safe hole, it is possible to detect the presence of a game machine in which the metal object has abnormally entered the safe hole. If such machines continue to operate, the operation of the amusement arcade will be adversely affected, so the operation must be stopped. Therefore, it is important to determine whether a metal body is abnormally easy to enter a safe hole.

When monitoring the status of the metal body with the new game machine 10, the card 173 can be replaced accordingly. The card 173 can be easily set for monitoring data simply by attaching it to the interface section 176 of the data processing device, and can be applied to various types of game machines by replacing game machines. In such cases, it is easy to change the monitoring data. The card 173 can be manufactured by copying one force as long as it is used for the same type of game machine 10. When performing more complicated processing, the card 173 can cope with more complicated processing by freely selecting a control device having a data processing speed corresponding to the processing.

In addition, if the algorithm of metal object detection is simple, the controller 30 is sufficient if an inexpensive 8-bit CPU is used, and if a complicated algorithm is required, Select one that uses a 16-bit CPU for high-speed processing. It is good. In any case, the scanning speed of the metal body is not affected by the CPU because the scanning is not performed via the CPU.
