Description

  The present invention relates to a gaming machine that plays a game by firing a game ball in a game area provided on a game board surface.

In a gaming machine that launches a game ball, such as a pachinko game machine, into a game area partitioned by a guide rail, and plays a game based on the game ball flowing down in the game area, There are provided prize-winning ports such as tulips (electric chews) and attackers, and fixed prize-winning ports such as general prize-winning ports (including start-up prize-winning ports not equipped with electric chews).
In addition, a plurality of game nails having a function such as distributing the game ball to the side approaching the opening of the prize opening and the side moving away from the opening are placed on the upper side of the various winning holes. In addition, the winning percentage of the game ball to each winning opening is influenced by the game nail.

  Further, a glass frame is provided on the front side of the game board so as to be separated from the game board by a thickness of a space that becomes a game area. That is, the game board is covered with a glass frame so as to be visible. In addition, the glass frame consists of the double glass which piled up and arrange | positioned two glass plates, for example. In addition, a gap is provided between the two glass plates.

In a gaming machine, a prize ball is paid out or a game is played based on the winning of a game ball in the above-described prize opening. Further, based on the result of the game, there occurs a state where the winning opening that opens and closes is opened and the game ball is likely to win, that is, a state where the payout of the prize ball is increased.
A game ball in such a gaming machine is a steel ball and has a property of being attracted (adsorbed) to a magnet. Therefore, it is possible to perform an illegal act to improve the winning rate of the game ball to the winning opening by applying the magnet from the front side of the glass frame and guiding the gaming ball in the winning opening direction.

  In addition, for illegal acts using magnets, the flow of game balls is stopped by magnets, and ball clogging occurs using game nails around the prize opening, guide rails near the prize opening, etc. Based on this, a lot of balls are collected, and the collected balls may be used for cheating to guide the game ball to the winning opening. There is also known a fraudulent act in which a non-contact type sensor that detects a game ball (for example, a sensor that detects a change in the impedance of a coil due to a game ball passing inside the coil) malfunctions due to the magnetic force of a magnet.

  For such fraudulent acts using electromagnets, devices that can detect magnetic force, such as magnetic sensors, are used in gaming machines, and there is a possibility that fraudulent acts are being conducted based on the detection of magnetic force. Is known (for example, see Patent Document 1 to Patent Document 4).

  By the way, the magnetic sensor generally has a narrow detection range, and many magnetic sensors are required to cover a relatively wide range of the game area from the back side of the game board surface. There are also a certain number of cases where detection sensors are concentrated in places where there is a high possibility of fraud due to magnets, for example, in the vicinity of the above-described general winning opening in the vicinity of the guide rail or in the vicinity of the starting winning opening. Magnetic sensor is required.

  On the back side of the game board surface, there are a flow path for guiding the game balls discharged from the prize opening to the back of the game board to the outside of the game machine, various devices that penetrate the game board and protrude to the back side, a display, A light emitting device using various LEDs, a driving device for various movable members, and the like are arranged, and various circuit boards (including a control circuit main board and sub board and a wiring connection board) are arranged. Has been.

Therefore, in order to be able to detect magnetism in many parts of the game area, it is difficult to dispose many magnetic sensors on the back of the game board, and the magnetic sensors are concentrated in some areas. It is also difficult to place. On the other hand, if the installation location of the magnetic sensor is secured, the arrangement of the display and various members arranged so as to protrude to the back side of the game board is limited.
In Patent Document 1 to Patent Document 4, attempts have been made to detect fraud more reliably by performing various devices on a device capable of detecting magnetism, but this is not always sufficient.

  The present invention has been made in view of the above circumstances, and a thin wire made of a ferromagnetic material is arranged in a net-like shape between two glasses of a glass frame, and does not directly detect the magnetism of the magnet. An object of the present invention is to provide a gaming machine capable of detecting an illegal act by a magnet by detecting the magnetism of a thin line magnetized by a magnetic field by a magnetic detection sensor.

In order to solve the above-mentioned problem, the gaming machine according to claim 1 has a game area in which a game ball flows down on the front side, and a game board having a ball entrance into which the game ball enters the game area. And a gaming machine comprising a transparent plate frame provided with a double transparent plate covering the front of the gaming area,
Between the double transparent plates, a ferromagnetic thin wire that is magnetized by a magnetic field and returns to the original when the magnetic field is cut is arranged in a net shape so as to cover at least the entrance, and extends to the outside of the game area. Located,
A magnetic detection sensor for detecting magnetism of a portion of the net-like thin wire extending outside the gaming area is provided at a position that does not overlap the gaming area in the front-rear direction;
When the magnetic detection sensor detects the magnetism of the thin wire, the magnetic sensor includes a signal output means for outputting a signal indicating that the magnetism has been detected.

  In the first aspect of the present invention, for example, any one of the game board entrances (for example, a prize entrance or a through-chucker that does not pay out a prize ball even if an inflow (passage) of game balls is detected) A magnet is applied from the front side of the transparent plate frame (glass frame) in the vicinity of the to guide the game ball to the entrance, cause the game ball detection sensor at the entrance to malfunction, or accumulate the game ball. When an illegal act of guiding the game ball to the winning opening is performed by the accumulated game balls, this can be detected by a magnetic detection sensor at a position that does not overlap the game area.

That is, when the magnet is brought close to the game area via the transparent plate frame, the magnetic field of the magnet magnetizes the fine mesh wire, and magnetism is generated from the ferromagnetic thin wire, which can be detected by the magnetic detection sensor. .
Since the magnetic detection sensor can be arranged at a position that does not overlap with the game area, it is not necessary to arrange the magnetic sensor on the back side of the game area of the game board on which various members are arranged. Becomes easier. In addition, since it is only necessary to detect magnetism generated from a net-like thin line, even a magnetic sensor with a narrow magnetic detection range may be arranged in a gaming machine. That is, since it is not necessary to arrange many magnetic sensors on the game board, the magnetic sensors can be easily installed and the cost can be reduced. Moreover, in order to be able to arrange many magnetic sensors, the arrangement of each member is not limited on the back of the game board. That is, a display, a lighting device, a movable device, and the like can be arranged on the game board without being restricted by the arrangement of the magnetic sensor.

According to a second aspect of the present invention, there is provided a ball game machine according to the first aspect of the invention, wherein the main body unit in which the game board is stored, a frame that supports the main body unit from the periphery, and a shaft that can be freely opened and closed on the frame. The supported transparent plate frame,
The magnetic detection sensor is provided in the main unit, and the net-like fine line and the magnetic detection sensor face each other in proximity to each other with the transparent plate frame closed.

  In the second aspect of the invention, the net-like thin line is provided on the transparent plate frame, whereas the magnetic detection sensor is provided on the main unit side that accommodates the game board. The main unit includes a game board, and the magnetic detection sensor may be provided in a portion other than the game area of the game board.

  When the transparent plate frame is closed, the thin wire of the transparent plate frame and the magnetic detection sensor of the main unit are arranged in close proximity to each other, so the magnetism of the fine wire magnetized by the magnet by the magnetic detection sensor is easy. Can be detected.

Also, on the thin wire side, no wiring is required, the magnetic detection sensor requires wiring, and the model of the gaming machine can be changed by removing and replacing the main unit with respect to the frame or transparent plate frame. ing. Therefore, when the main unit is replaced, a magnetic detection sensor is provided on the main unit side, and no wiring is required between the thin wire of the transparent plate frame and the magnetic detection sensor of the main unit. Even if a thin line is provided, it is possible to prevent the work efficiency of model exchange from deteriorating.
In other words, even if the thin line as a part of the system that detects magnetism is on the transparent plate frame side, the magnetic detection sensor on the main unit side and the thin line are not connected. The thin wire and the magnetic detection sensor do not affect the efficiency, and the model exchange can be easily performed.

  According to the present invention, it is possible to detect a magnet without providing many magnetic detection sensors on the back of the game board. Thereby, the structure for detecting fraud by a magnet can be simplified and cost reduction can be aimed at. In addition, since it is not necessary to arrange a plurality of magnetic detection sensors at positions corresponding to the game area, the arrangement of each member on the game board is not limited by the magnetic detection sensor, and each variation winning device of the game board, The degree of freedom of arrangement of members such as a display, a lighting device, and a movable device can be increased.

Yes.

In such a pachinko gaming machine P, a thin wire 50 made of a net-like ferromagnetic material is provided between the double glass plates 10 of the glass frame 4 as shown in FIG.
The fine lines 50 are formed in, for example, an oblique lattice shape composed of thin lines having inclinations opposite to each other, or a lattice-like mesh shape composed of vertical and horizontal thin lines.
Moreover, the thin wire | line 50 is arrange | positioned in the state affixed on the front side of the glass plate 10 inside the double glass plate 10 (side near the game board 3).

The fine wire 50 is, for example, an iron wire (super extra fine steel wire) as a ferromagnetic material. For example, an extra fine steel wire used in a fine mesh for screen printing has a wire diameter of 0.02 mm or less. Yes.
When the player views the game area 31 of the game board 3 through the thin line 50, the thin line 50 needs to be thin enough not to obstruct the player's visual recognition. The thin wire 50 is preferably as thin as possible. For example, a thin wire having a wire diameter of about 0.01 mm to 0.08 mm can be suitably used.

Further, the thin wire 50 may be a stainless steel wire, and in this case, a steel wire made of stainless steel exhibiting ferromagnetism can be used.
The ferromagnetic material in this embodiment is a material that is magnetized by a magnetic field and disappears (returns to the state before magnetization) when the magnetic field is cut off. After that, even if the magnetic field is cut off, it does not have spontaneous magnetization.

  The mesh size of the thin wire 50 is determined in consideration of visibility and the strength of the magnetic force when magnetized. The mesh size is determined experimentally together with the wire diameter of the thin wire 50. For example, when a magnetic detection sensor generally used in a pachinko gaming machine P is used and a magnet is brought close to the thin line 50, whether or not the magnetic detection sensor 51 in the vicinity of the thin line 50 can be similarly detected, and which of the thin lines 50 Experiment whether it can detect even if a magnet is brought close to the position. In this case, finally, the diameter of the fine wire 50 that can be detected by the magnetic detection sensor 51 through the double glass plate 10 having the fine wire and the size of the mesh are determined.

  In this embodiment, a magnetic detection sensor (game ball detection sensor) 51 for detecting magnetism when the thin wire 50 is magnetized is provided on the game board 3 of the main body unit including the front frame 2 and the game board 3. .

A magnetic detection sensor 51 is provided in the front portion outside the game area 31 divided by the guide rails 32 of the game board 3. In this embodiment, only one magnetic detection sensor 51 is provided in the lower right part toward the outside of the game area 31 of the game board 3.
When the glass frame 4 is closed, the magnetic detection sensor 51 of the game board 3 is in a position facing the net-like thin line 50 provided on the glass frame 4 that can be opened and closed with respect to the main unit. .

Therefore, the magnetic detection sensor 51 is disposed at a position close to the net-like thin line 50 provided between the double glass plates 10 of the glass frame 4, and the thin line 50 is formed by a magnet used for fraud as described above. When magnetized, the magnetism generated by the thin wire 50 can be detected.
In addition, the wiring of the magnetic detection sensor 51 is basically the same as the conventional magnetic detection sensor, as the control device (control board) provided on the back surface of the game board 3, for example, the main control processing unit 11 described above, the production The display control unit 12a, the special symbol display control unit 12b, the lamp control processing unit 12c, and the voice control processing unit 12d are connected to any one of the control units.

The magnetic detection sensor 51 outputs a signal to any of the above-described control units that control the pachinko gaming machine P, for example, when magnetism of a predetermined strength or higher is detected.
For example, a signal from the magnetic detection sensor 51 is sent to the main control processing unit 11, and error processing is performed based on this signal, or a signal output indicating an illegal act to an external management device is performed. Therefore, the magnetic detection sensor 51 also serves as a signal output unit that outputs a signal indicating that magnetism has been detected. On the control device side, the output from the magnetic detection sensor 51 (analog output) is determined, When outputting a signal indicating that magnetism has been detected, for example, a control device such as the main control processing unit 11 may be used as the signal output means.
Moreover, it is good also as a structure which outputs a signal to the warning lamp of an island installation, and turns on the warning lamp of an island installation.

  In this pachinko gaming machine P, a net-like ferromagnetic thin wire 50 provided between the double glass plates 10 of the glass frame 4 covers the entire front side of the game area 31 of the game board 3. When the magnet is brought into contact with or close to the glass frame 4 so that magnetism acts from the front side of the glass frame 4 toward the game area 31, the fine wire 50 of the glass frame 4 is magnetized.

  Further, the thin line 50 is also provided in a portion of the double glass plate 10 of the glass frame 4 facing the outside portion of the game area 31 of the game board 3, and the thin line 50 and the outside of the game area 31 of the game board 3. When the fine line 50 is magnetized by a magnet, the magnetism generated from the fine line 50 can be detected by the magnetic detection sensor 51.

Thereby, even if the magnet is brought close to or in contact with any portion of the glass frame 4 facing the game area 31, it is possible to detect that the magnet is brought close to or brought into contact with the glass frame 4 with one magnetic detection sensor. it can.
That is, outside the game area 31 of the main unit composed of the front frame 2 and the game board 3 (the part excluding the front frame 2 and the game area 31 of the game board 3 that overlaps the front and rear), and the double of the glass frame 4 One magnetic detection sensor 51 is disposed in a portion facing the glass plate 10 of the first, and the mesh-like thin line 50 is disposed so as to integrally cover the portion facing the game area 31 and the portion facing the magnetic detection sensor 51. Thus, the proximity of the magnet can be detected over the entire game area 31.

  Therefore, it is not necessary to arrange a plurality of magnetic detection sensors 51 having a generally narrow magnetic detection range on the back side of the game board 3, and it is not necessary to arrange one more. Thereby, the improvement of the space efficiency of the back surface of the game board 3 in which many members are arrange | positioned can be aimed at. Further, when the magnetic detection sensor 51 is arranged on the back surface of the game board 3, the arrangement location of the magnetic detection sensor 51 is limited, and it is possible to prevent the range from being limited so that the magnet in the game area 31 can be detected.

Further, since the plurality of magnetic detection sensors 51 are arranged at desired positions on the game board 3, it is possible to prevent the positions of other members arranged on the game board 3 from being restricted.
Further, by reducing the number of the magnetic detection sensors 51, the cost can be reduced and the manufacturing process can be simplified.

  In general, when a model change of the pachinko gaming machine P is performed at a game store, the entire pachinko gaming machine P is replaced, and the machine frame 1, the glass frame 4, etc. are left and only the main unit is replaced. There is. When only the main unit is replaced, the thin net wire 50 on the glass frame 4 side and the magnetic detection sensor 51 on the main unit side are not connected by wiring or the like, and when the main unit is removed from the machine frame 1 It is not necessary to remove or change the wiring of the magnetic detection sensor 51, and it is also necessary to perform wiring work of the magnetic detection sensor 51 when installing a new main unit having the magnetic detection sensor 51. Absent. Wiring of the magnetic detection sensor 51 is performed, for example, when a member is attached to the game board 3 or the front frame 2.

  In the above embodiment, the net-like thin lines are arranged on substantially the entire surface of the glass plate 10, but the net-like thin lines are not necessarily arranged over the entire surface of the glass plate 10, for example, provided on the game board 3. While covering mainly the part which covers the front side of each winning opening, you may make it cover the part of the magnetic detection sensor 51. FIG. In this case, it is necessary to be in a state in which all are connected together, and for example, a shape in which a hole (not a mesh) without the fine wire 50 is provided at a plurality of locations of the mesh composed of the fine wire 50 may be provided. .

In this case, the portion where the thin line 50 is present and the portion where the thin line 50 is not present are visually slightly different and may be used as a part of the design.
