Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko game machine, and more particularly to a pachinko game machine having a door with means for detecting a pachinko ball.

[0002]

2. Description of the Related Art Generally, a pachinko game machine has a board surface (base board) that forms a space for moving a pachinko ball, a glass plate that covers the pachinko ball at a constant interval, a pachinko ball, and the board surface and the glass plate. And a projection mechanism for projecting into a space partitioned by. Pachinko game machine,
The board surface is installed so that it is substantially parallel to the vertical direction. On the board surface, a plurality of winning holes will be awarded when a pachinko ball enters the board surface and is ejected from the board surface, and one exit hole from which the pachinko balls that did not enter the winning hole are finally collected and ejected from the board surface. And are provided.

In addition, a large number of pins (nails) have a length corresponding to the diameter of the pachinko ball so that the pachinko ball falling along the plate surface frequently collides with the board surface and causes fluctuations in the movement direction. It is provided substantially vertically while protruding from the board surface. These pins, while repelling or refracting the striking pachinko ball, lead to the winning hole in some cases, and in some cases, guide it away from the winning hole. Has been decided.

As shown in FIG. 2, normally, in a pachinko parlor, the pachinko game machine 10 is operated by a user 1000.
In order to make it easier to use, the two units are arranged adjacent to each other in two rows with their backs facing each other. Further, in the parlor, there are provided a group of pachinko game machines 10 arranged in this way, forming a so-called island shape. Here, in FIG. 2, the opposite pachinko game machine 1
A typical size of a distance of 0 and a gap between adjacent game machines 10 is shown.

By the way, in a pachinko parlor in which a large number of such pachinko game machines are arranged, it is necessary to manage the winning situation in each pachinko game machine. That is,
This is because it is necessary to find a machine with an uneven trajectory of a pachinko ball or a machine with an abnormal trajectory, and perform replacement or repair. For example, if a machine that is unusually easy to win is left unattended, management damage to the pachinko parlor becomes great, so it is necessary to find such a machine. Also,
On the other hand, if there is a machine that is unusually difficult to win, the parlor will be disliked by the customer, so it is necessary to find such a machine. Also, it is necessary to detect an illegal act such as guiding a pachinko ball with a magnet or the like during the execution of the game.

[0006] Conventionally, as a pachinko ball detection device for such a purpose, the applicant of the present invention has filed Japanese Patent Application No. 2-244898.
In the specification of Japanese Unexamined Patent Publication (Kokai) No. 4-122375, it has been proposed to construct a pachinko ball sensor using a transmission line and a reception line. That is, a plurality of outgoing lines and outgoing lines are attached in parallel to one side of the glass substrate of the door of the pachinko game machine, and a plurality of outgoing lines and incoming lines are placed in parallel, and the transmission line and the electromagnetic line are connected. A sensor configured to be attached to the opposite surface of the glass substrate so as to be electrically coupled thereto.

In this sensor, the corresponding transmission line and reception line are connected to the transmission circuit and the reception circuit of the management device,
By sending a signal current to each transmission line in sequence and sequentially extracting an induction current induced by the signal current for each reception line, the presence or absence of a pachinko ball is detected from the induction current received by the reception circuit and the signal current flows. The position of the pachinko ball can be detected by knowing the combination of the transmitting line that is receiving the induced current and the receiving line that is receiving the induced current.

That is, in this sensor, the intersection of the transmission line and the reception line serves as a detection unit. Then, those detection units are arranged in a matrix.

With such a sensor, the number of hit balls is counted,
That is, when counting the number of balls that are hit in the game area by the projection mechanism, pay attention to one of the detection units in the area where the ball passes and determine whether the pachinko ball has passed that detection unit. This is done by monitoring and detecting the signal when passing. The number of balls is counted by counting the detection signal with a counter.

[0010]

According to this type of detection device, the position of the pachinko ball on the board surface of the pachinko game machine,
As a result, data representing the trajectory can be easily and quickly obtained. Further, since the detection matrix is attached to the door of the pachinko machine, there is a particular advantage that the structure can be made to have no relation to the design of the pachinko machine itself by simply replacing the door.

As shown in FIG. 11, the door is attached to a pachinko game machine (hereinafter, also simply referred to as a pachinko machine) 10 at the left end by a hinge (not shown) so as to be openable and closable for adjusting the nails 13 and the like. There is. Two front glasses are attached to the door 80, one of which is a surface glass body 16 covering the outside, and the other of which is an inner glass body 17 on the inner side (board side). Surface glass body 16 and inner glass body 17
Means that when the door 80 is closed, as shown in FIG. 6, the board surface 11 is covered along the board surface 11. Normally, the door 80 is closed and locked during the game so that the player cannot open it. When a pachinko ball is caught between the nails 13 or stuck in the winning hole during play, the player calls a staff member. The called staff uses the key to open the door of the pachinko machine, eliminates the trouble, and then closes and locks the door again.

By the way, there may occur a case where it looks like a closed state but is not completely closed (a so-called half-opened state) due to an error or a mechanical failure. In such a case, unlike the case where the state of the space on the board surface is regular, the regular gaming state cannot be provided for the pachinko machine. Therefore, the pachinko parlor side needs to recognize that the door of each pachinko machine is completely closed. Of course, it is necessary to monitor unauthorized opening and closing of the door by the player. Conventionally, a means for detecting such an incompletely closed state of a door is known by a pachinko machine manufacturer and provided in each pachinko machine itself.

However, the presence or absence of such detection means and the detailed specifications may differ depending on the pachinko game machine manufacturer, and in some cases, machines of a plurality of manufacturers may be mixedly arranged in one pachinko parlor. As a result, it would be convenient to be able to independently check the opening and closing of the door regardless of the manufacturer or model of the pachinko game machine.

In view of such circumstances, the present invention has an object of providing a device capable of performing a door opening / closing check by utilizing the pachinko ball detecting device previously proposed by the present applicant. And

[0015]

In order to achieve this object, a door open / close detection device according to the present invention is attached to a door that can be opened / closed in a pachinko game machine, and a metal body on a board surface on which a game area is set is magnetized. Which are arranged in a matrix in order to detect automatically, a means for setting a door opening / closing detection point at a position on the sensor facing the stationary metal body protruding on the board surface, and the means for setting the door opening / closing detection point When the output value of the sensor falls below a predetermined reference level,
Door opening / closing detection processing means for determining that the door is in an open state.

In this device, the door open / close detection point is preferably set at a position on the door relatively far away from the board surface when the door is opened.

The stationary metal body on the board is, for example, at least one of a windmill, a nail, and an accessory device.

A plurality of points may be set as the door opening / closing detection points, and in this case, the door opening / closing detection processing means has an output value lower than the reference level at at least one of the plurality of points. When I did
It is determined that the door is open.

The position information of the door opening / closing detection point may be supplied from the outside for each pachinko game machine. At that time, the position information of the door opening / closing detection point may be supplied from outside together with the reference level at each point. The door opening / closing detection processing unit preferably performs the processing periodically each time new data is fetched by the sensor.

Further, preferably, it further comprises display means for displaying the detection processing result of the door opening / closing detection processing means.

[0021]

The present invention relates to the application of a pachinko ball detection device using a sensor (hereinafter referred to as a matrix sensor) attached to the door of a pachinko game machine, as proposed by the present applicant. . Originally, when detecting a pachinko ball moving on the board surface of a pachinko game machine, metal objects other than the pachinko ball on the board surface such as nails, windmills, and accessories become noise when the pachinko ball is detected, and should be treated as things that should be removed. However, in the present invention, the open / closed state of the door is automatically and surely detected by effectively utilizing such a signal.

When the door of the pachinko game machine is not completely closed, the position of the matrix sensor on the free end side of the door is farther from the board surface than the original position. Therefore, when the door is not in the completely closed state, it is considered that the reaction with respect to the metal body on the board is lowered at such a position. Therefore, in the present invention, such a position is selected as a door opening / closing check point to check the output of the matrix sensor. As a result, it is possible to detect the open / closed state of the door using the matrix sensor.

Next, the operation of this pachinko ball detection device will be described.

Address signals and control signals from the information processing device 30 are output via the CPU connector 46. The processing flow is shown in FIG.

First, the adjustment of the device in hitting ball detection will be described. Since various metals such as the pins 13 and the guide rails 12 are arranged on the board surface 11, the reception signals from the reception lines in the vicinity thereof do not reach the saturation value depending on the presence of those metals. Adjust the A / D converter 75.

When the pachinko game machine is activated, the information processing device 30 reads the stored contents of the card 173,
It is stored in the memory 30b.

When the start signal is transmitted from the information processing device 30 to the sequence control circuit 47, the sequence control circuit 47 divides the basic clock of 16 MHz according to the required clock frequency to generate a transmission clock. hand,
Output. The transmission clock from the sequence control circuit 47 is waveform-shaped from the digital signal to the analog signal by the bandpass filter 48, amplified by the amplifier 49, and sent to the transmission connector 41.

Further, the transmission signal is amplified by the amplifier 42 in the transmission circuit 40. Analog multiplexer 44
Is a channel switched by the channel switching logic 43 to sequentially operate the totem pole driver 45, whereby the totem pole driver 45 sequentially outputs the signals amplified by the amplifier 42 to the transmission line 22 (step 91). .

Then, an electromotive force is generated by the electromagnetic induction action on each reception line 26 that intersects the transmission line 22 to which the signal is transmitted. At this time, when a pachinko ball that is a metal approaches the detection unit 20a, the detection unit 20a is affected by the influence.
Then, the magnitude of the electromotive force (induced current) of the reception line 26 changes.

The reason for this is not always analyzed clearly at present, but it can be considered as follows. First, pachinko balls are ferromagnetic materials because iron is the main component. Therefore, it occurs on the transmission line 22,
The magnetic flux that has spread in the space will be focused on the pachinko balls, and the distribution of the magnetic flux that links the reception lines will change. In addition, an eddy current is generated in the pachinko ball in the direction in which the magnetic flux generated by the transmission line 22 is canceled. Because of these, the induced current changes. Which is dominant depends on the relative positional relationship between the pachinko ball and the transmission line 22 and the reception line 26. Also, whether or not the magnetic flux interlinking the reception line 26 increases depends on the relative positional relationship with the pachinko ball. Furthermore, it also depends on whether or not metal is present in the background. In either case, it is sufficient that the change can be detected.

On the receiving side, the receiving circuit 50 is synchronized with the transmitting circuit 40 by the sequence control circuit 47, and each CT 51
A signal is received from each reception line 26 via. As shown in FIG. 9, the voltage due to the induced current appearing in the plurality of reception lines 26 is converted to 10 times the magnitude by the CT 51.
Since the conversion is performed by CT51, it is not necessary to increase the amplification degree of the amplifier on the receiving side. CT51
Are the receiving lines 26 and the receiving circuit 5 of the matrix sensor 20.
The analog multiplexer 52 of 0 is insulated, and noise from the pachinko game machine 10 is prevented from entering the receiving circuit 50.

The analog multiplexer 52 has a CT 51
The signal from each receiving line 26 passing through is switched by the channel switching logic 54 and sequentially output. The signal from the analog multiplexer 52 is amplified 100 times by the amplifier 53 (step 92).

The received signal is received by the receiving connector 55 and the amplifier 7.
1. Amplification and detection are performed through the bandpass filter 72. The received signal from the bandpass filter 72 is an analog signal, and this analog signal is
The full-wave rectification / amplifier 73 performs waveform shaping. The signal from the full-wave rectifier / amplifier 73 is supplied to the low-pass filter 7
Averaging is performed by integration processing at 4a and 74b.

Next, the received signal is the A / D converter 75.
Sent to The A / D converter 75 converts the signal from the receiving line 26 into a digital signal in a predetermined bit unit such as 12 bits, and outputs the converted signal (detection data) under the control of the sequence control circuit 47. Then, after the above-mentioned data conversion is performed by the data conversion circuit unit 200, it is registered in the bidirectional RAM 76 (step 93).

That is, the bidirectional RAM 76 receives the write signal from the sequence control circuit 47, and the information processing apparatus 3 receives the write signal.
After the detection data is recorded irrespective of the operation of 0, the address is incremented by +1 at each scanning cycle (for example, every one clock) based on the clock signal output from the sequence control circuit 47 (step 94) to detect the detection data. The conversion data (computation data) of is registered in a different address for each detection unit 20a.

The above operation is repeated every scanning cycle. That is, the analog multiplexer 5 of the receiving circuit 50 is provided every scanning cycle.
2 switches the signal from each receiving line 26 (step 9
5) The above operation is performed 32 times on the 32 reception lines 26. When this is completed (step 96), at that point, the analog multiplexer 44 of the transmission circuit 40 switches the transmission line 22 (see step 97), the same processing is repeated 32 times again, and the detection units 20a are sequentially detected. The operation data is registered in a different address of the bidirectional RAM 76 in association with the detection unit 20a.

Therefore, the information processing device 30 reads out the operation data registered in the bidirectional RAM 76, so that the pachinko machine can be moved to any position (detection unit 20a) at any time, independently of the detection signal processing operation. Whether or not a ball is present can be determined at any time using arbitrary search conditions.

Now, according to the present invention, such a pachinko ball detecting device is not limited to a pachinko ball, but may be another metal body such as a nail or a windmill (having a plurality of wings and hitting a pachinko ball when hit by a pachinko ball). It rotates around to the right or left)), etc. That is, usually, in detecting a pachinko ball, these reactions that should be excluded as noise are effectively used.

In this embodiment, as shown in FIG. 11, the hinge of the door is at the left end when facing the board surface. Therefore,
When the door is in the half-opened state, the front glass moves away from the board surface 11 as it goes to the right. As a result, the closer to the right end (that is, the free end side) of the door, the farther the metal body attached to the board 11 is, the more difficult it becomes to detect their reactions. Such door opening / closing detection points are set at several points on each pachinko machine, and when the reaction at any of those points falls below the reference level, it is determined that the door is not completely closed. The door opening / closing detection point may be any metal body that is fixed on the board surface 11 and protrudes. Actually, nails, windmills, accessory devices, and the like located on the board surface 11 near the right end are conceivable. As shown in FIG. 15, in this embodiment, the wind turbine 985 having a greater reaction than the nail 13 does.
Use the position of. When selecting door open / closed detection points for a specific model, all matrix coordinate points (3
2 × 32 points) may be examined to find a point having a large reaction, and a door opening / closing detection point may be selected from the points.

FIG. 12 shows a block diagram of the software configuration of this embodiment. This software includes a door opening / closing check process 981 and receives a parameter group including a door opening / closing detection point 980 from the card 173 and input read data 760 from the bidirectional RAM 76 as input information. Here, as will be described later, raw data is received from the bidirectional RAM 76 instead of the operation data. Therefore, the above-mentioned offset data and slice data are both set to 0 for the door opening / closing detection point.
It is set to 0H. That is, the data conversion circuit unit 200 of FIG.
Outputs the input data as is. Therefore, if only for this processing, the data conversion circuit unit 200 is unnecessary. The door open / close check processing 981 sets a door open / close flag 982 (described later) based on these input information.

FIG. 13 shows a processing flow of the door opening / closing check 981 in this embodiment. In order to explain this processing, the table configuration used in this processing will be described with reference to FIG.

The table used in this processing is a 1-byte door opening / closing flag 982 (FIG. 14 (a)) and a door opening / closing detection point 983 (FIG. 14 (b)). Door open / close flag 98
Reference numeral 2 is for storing information indicating the open / closed state of the door, where "0" indicates the door closed state and "1" indicates the door opened state. In this embodiment, up to five door opening / closing detection points can be set. Each point is defined by xy coordinates 984 and 985 of a 32 × 32 detection matrix. In addition, a detection level 986 that functions as a threshold value for signal determination is also defined for each point. With this configuration, it is possible to make the detection level different for each set point.

Therefore, according to FIG. 13, the door opening / closing check 98 is performed.
The processing procedure of No. 1 will be described. This processing is executed periodically (for example, every scan cycle of the detection matrix).

First, it is checked whether all the door opening / closing points 983 have been checked (991). Initially,
Since it is not finished, the process proceeds to the next step 992, and it is checked whether or not the point is set in the entry of the first point. If the point is set, the raw data of the position corresponding to the coordinate of the point is extracted from the read data 760, and the detection level 98 set for the point is set.
6 (993). If the raw data is lower than the detection level, it is determined that the door is not completely closed, and the door open / close flag 982 is set to "1" (open state) (994).
The process ends. If the raw data is larger than the detection level, there is no problem with that point and the process proceeds to check the next point (991). When all points have been completed, the routine proceeds to step 995. If no checkpoint is set in step 992, it is determined that there is no subsequent point setting, and the flow advances to step 995. Step 995
Then, "0" (closed state) is set to the door opening / closing flag 982. This flag information is read out periodically and displayed on the indicator 1024. Alternatively, at the same time, it is sucked up by a host computer (not shown) in the parlor connected via a communication line, and the door open / closed state of the pachinko machine of the entire parlor is monitored.

In this embodiment, the door opening / closing detection point is stored in the card 173. This is because when the pachinko game machine is exchanged, the door opening / closing detection point of a new machine is supplied by a card so that the mode can be quickly and easily performed. However, the present invention
It is not limited to this. It may be configured to be stored in another storage medium, for example, the memory 30b.
