Abstract

PROBLEM TO BE SOLVED: A conventional pachinko machine is damaged by an illegal act of illegally acquiring a game ball by a radio wave transmitter.
When a pachinko ball P passes through a passage hole 101a, light emitted from an LED 103 is not received by a PD 104, and a ball passage detection signal is output from a photosensor 101. In addition, the static magnetic field generated by the permanent magnet 107 changes according to the passage of the pachinko sphere P, and a sphere passage detection signal is output from the magnetic sensor 102. Based on the detection signals of these sensors 101 and 102, the main CPU 31 recognizes that the pachinko ball P has passed a predetermined area of the game member.

Description

  The present invention relates to a gaming machine including a gaming ball detection device that detects a gaming ball that has passed through a predetermined area of a gaming member.

Conventionally, as this type of gaming machine, for example, there is a pachinko machine disclosed in Patent Document 1 below. The game board surface of this pachinko machine is provided with a start winning opening, a general winning opening, and a large winning opening through which a game ball can win. When a game ball wins in these winning openings, the ball tank passes through the ball passage. Thus, the game ball is paid out to the upper plate, and the player can obtain a predetermined profit. The ball passage is provided with a magnetic detection sensor that detects that a game ball has passed. The magnetic detection sensor includes a detection coil. When the coil is energized, a magnetic field is formed in a hole through which the game ball passes, and a magnetic flux is generated in the hole. When a metal game ball passes through the hole, the magnetic flux interlinking the hole changes, so that it is detected that the game ball has passed through the ball passage.
JP 2003-310871 A (paragraphs [0015] to [0022], [0045] to [0049])

  However, the magnetic detection sensor in the conventional pachinko machine as shown in Patent Document 1 described above has a detection coil that detects a change in magnetic flux generated in the space near the passage hole of the game ball by electromagnetic induction. Since the passage of the sphere is detected, it is easily affected by an electromagnetic wave that causes a magnetic field change in the space near the passage hole of the game sphere. For this reason, conventionally, a fraudulent act of illegally acquiring a game ball (so-called radio wave goto) by intentionally sending an electromagnetic wave into the space near the passage hole of the game ball by a radio wave transmitter and causing the magnetic detection sensor to make a false detection. ).

The present invention was made to solve such a problem, and in a gaming machine equipped with a gaming ball detection device that detects a gaming ball that has passed through a predetermined area of a gaming member provided on a gaming board,
The game ball detection device includes: a first detection unit that detects that a game ball has passed through a predetermined region by detecting a change in a received light amount of light emitted from the light emitting element and received by the light receiving element; And a second detection means for detecting that a game ball has passed through a predetermined area by detecting a change in a galvanomagnetic effect caused by an element placed in a static magnetic field generated by the means. And

  According to this configuration, when the game ball passes through a predetermined area of the game member, the first detection means detects the passage of the game ball by a change in the amount of light received by the light receiving element, and the second detection means The passage of the game ball is detected by a change in the galvanomagnetic effect caused by the element placed therein. For this reason, even if an electromagnetic wave is blown to a predetermined area of the game member from a radio wave transmitter or the like, the first detection means detects the passage of the game ball by a change in the amount of received light, and thus is not affected by the electromagnetic wave. Even in the second detection means, even if a weak magnetic field change due to electromagnetic waves occurs in the static magnetic field around the element, the current magnetic effect caused by the element is hardly affected. Unlike conventional detection devices such as a coil sensor for detection, it is not affected by electromagnetic waves. As a result, it is possible to prevent erroneous detection due to electromagnetic waves generated by the radio wave got and to reliably prevent an illegal act of illegally acquiring a game ball. In addition, when two different detection means of the first detection means and the second detection means are used in combination, the detection accuracy of the game ball is improved, and the game ball continuously passes a predetermined area of the game member Even so, the number of passing balls can be detected accurately.

  Further, the present invention is characterized in that the game ball detecting device is provided with a metal plate inside the device until the magnetic flux generated by the magnetic field generating means reaches the element causing the galvanomagnetic effect.

  According to this configuration, the magnetic resistance until the magnetic flux generated by the magnetic field generating means reaches the element causing the galvanomagnetic effect is reduced by the metal plate, and the magnetic force generated by the magnetic field generating means efficiently causes the galvanomagnetic effect. To be told. For this reason, the range in which the magnetic force generated by the magnetic field generating means extends to the element that causes the galvanomagnetic effect is widened, so that the degree of freedom of the relative arrangement position between the magnetic field generating means and the element that causes the galvanomagnetic effect increases. The degree of freedom in machine design is improved.

  In addition, the present invention is characterized in that the element causing the galvanomagnetic effect is a Hall element.

  According to this configuration, when the game ball passes through a predetermined region of the game member, a magnetic field change occurs in the static magnetic field generated by the magnetic field generating means, and the Hall voltage generated as a current magnetic effect inside the Hall element due to the change in the magnetic field. Changes appear. By detecting the change in the Hall voltage, it is detected that the game ball has passed the predetermined area of the game member. At this time, the change in the Hall voltage appears as a change in carrier drift inside the Hall element, and is detected in a very short time. For this reason, compared with the case where the conventional coil sensor is used, passage of a game ball can be detected at high speed and with high precision.

  In addition, the present invention is characterized in that the element causing the galvanomagnetic effect is a magnetoresistive element.

  According to this configuration, when the game ball passes through a predetermined area of the game member, a magnetic field change occurs in the static magnetic field generated by the magnetic field generating means, and the magnetic field generated as a galvanomagnetic effect inside the magnetoresistive element due to the change in the magnetic field. Changes appear in the resistance effect. By detecting the change in the magnetoresistive effect, it is detected that the game ball has passed the predetermined area of the game member. Also at this time, the change in the magnetoresistive effect appears as a carrier drift change in the magnetoresistive element and is detected in a very short time. For this reason, also in this case, it is possible to detect the passage of the game ball at a high speed and with high accuracy as compared with the case where the conventional coil sensor is used.

  According to the gaming machine of the present invention, as described above, an illegal act of illegally acquiring a game ball by electromagnetic waves can be surely prevented, and two of the first detection means and the second detection means can be prevented. By using different detection means together, the detection accuracy of the game ball is improved.

  When the pachinko sphere P does not pass through the passage hole 101 a, the light emitted from the LED 103 is received by the PD 104 through the reflection plate 105. At this time, a high level detection signal is output from the photosensor 101. On the other hand, when the pachinko sphere P passes through the passage hole 101a as indicated by an arrow in FIG. 5A, the light emitted from the LED 103 is transmitted by the pachinko sphere P when the pachinko sphere P passes through the passage hole 101a.

  When the pachinko ball P does not pass through the passage hole 101a, the static magnetic field generated by the permanent magnet 107 does not change, and the Hall voltage generated by the Hall element 106 remains constant and does not change. At this time, a high level detection signal is output from the magnetic sensor 102. On the other hand, when the pachinko sphere P passes through the passage hole 101a as indicated by an arrow in FIG. 5A, the static magnetic field generated by the permanent magnet 107 changes according to the passage of the pachinko sphere P. At this time, a low level detection signal (ON signal) is output from the magnetic sensor 102. The magnetic sensor 102 detects that the pachinko ball P has passed through the passage hole 101a by detecting a change in the Hall effect caused by the Hall element 106 placed in the static magnetic field generated by the permanent magnet 107 as a change in Hall voltage.

Each winning opening 12b to 12d and the passing gate constitute a gaming member provided in the transparent game board 12, and each winning opening 12b to 12d and the opening area of the passing gate constitute a predetermined area of the gaming member. The fact that the pachinko ball P has passed the predetermined area of the gaming member is recognized by the main CPU 31 as described above.

At this time, a low level detection signal is output from the photosensor 101 and the magnetic sensor 102. When the low-level detection signal is input, the main CPU 31 determines that the pachinko ball P has passed through the passage hole 101a, and performs payout processing of the pachinko ball P in accordance with the winning prize opening or the passing gate that has passed.

  According to the pachinko machine 10 according to the present embodiment, as described above, when the pachinko ball P passes through predetermined areas of game members such as the winning holes 12b to 12d and the passage gate provided in the transparent game board 12, In the photosensor 101, the passage of the pachinko sphere P is detected by the change in the amount of light received by the PD 104, and in the magnetic sensor 102, the passage of the pachinko sphere P is detected by the change in the Hall voltage caused by the Hall element 106 placed in the static magnetic field. Is done. For this reason, even if an electromagnetic wave is blown to a predetermined area of the game member from a radio wave transmitter or the like and an illegal act is performed, the photosensor 101 detects the passage of the pachinko ball P by a change in the amount of received light. Not affected. In the magnetic sensor 102, even if a weak magnetic field change due to electromagnetic waves occurs in the static magnetic field around the Hall element 106, the change in Hall voltage caused by the Hall element 106 is hardly affected. Unlike conventional detection devices such as coil sensors that detect changes themselves, they are not affected by electromagnetic waves. As a result, it is possible to prevent erroneous detection due to electromagnetic waves generated by the radio wave got and to reliably prevent an illegal act of acquiring the pachinko ball P illegally. Further, the two different detection means of the photo sensor 101 and the magnetic sensor 102 are used in combination, so that the detection accuracy of the pachinko ball P is improved, and the pachinko ball P continuously passes through a predetermined area of the game member. However, the number of passing spheres can be detected accurately.

  In the present embodiment, the magnetic resistance until the magnetic flux generated by the permanent magnet 107 reaches the Hall element 106 is reduced by the metal plate 108, and the magnetic force generated by the permanent magnet 107 is efficiently transmitted to the Hall element 106. For this reason, the magnetic force generated by the permanent magnet 107 is efficiently transmitted to the Hall element 106 and the range in which the magnetic force is applied to the Hall element 106 is widened, so that the relative arrangement position between the permanent magnet 107 and the Hall element 106 is increased. The degree of freedom of design of the pachinko machine 10 is improved.

  In the present embodiment, since the element that causes the galvanomagnetic effect is the Hall element 106, when the pachinko ball P passes through a predetermined region of the game member, a change in magnetic field occurs in the static magnetic field generated by the permanent magnet 107. A change appears in the Hall voltage generated inside the Hall element 106 due to the change in the magnetic field. By detecting the change in the hall voltage by the main CPU 31, it is detected that the pachinko ball P has passed the predetermined area of the game member. At this time, the change in Hall voltage appears as a change in carrier drift inside the Hall element 106 and is detected in a very short time. For this reason, compared with the case where the conventional coil sensor is used, passage of the pachinko sphere P through a predetermined region can be detected at high speed and with high accuracy.

  In the above-described embodiment, the case where the Hall element is used as the element that causes the galvanomagnetic effect has been described. However, it is also possible to use a magnetoresistive element instead of the Hall element.

  According to this configuration, when the pachinko ball P passes through a predetermined region of the game member, a magnetic field change occurs in the static magnetic field generated by the permanent magnet 107, and this magnetic field change causes a galvanomagnetic effect inside the magnetoresistive element. Changes appear in the magnetoresistive effect. By detecting the change in the magnetoresistive effect, the main CPU 31 recognizes that the pachinko ball P has passed the predetermined area of the game member. Also at this time, the change in the magnetoresistive effect appears as a carrier drift change in the magnetoresistive element and is detected in a very short time. For this reason, also in this case, it is possible to detect the passage of the pachinko sphere P through a predetermined region at a high speed and with a higher accuracy than when a conventional coil sensor is used.

  In the above-described embodiment, the case where the permanent magnet 107 is used as the magnetic field generation unit has been described. However, the magnetic field generation unit can be appropriately changed as long as it generates a static magnetic field.

  In the above-described embodiment, the case where the magnetic sensor 102 is provided on the upper surface of the photosensor 101 has been described. However, the pachinko ball is detected by the two sensors of the photosensor 101 and the magnetic sensor 102 at the same time. If so, the arrangement of the sensors 101 and 102 can be changed as appropriate.

  In the above embodiment, the case where the metal plate 108 is provided at a position where the magnetic flux generated by the permanent magnet 107 reaches the Hall element 106 has been described. However, the metal plate 108 may be omitted. . In the above embodiment, the case where the Hall element 106 and the permanent magnet 107 are provided on the same plane along the side surface of the storage case of the magnetic sensor 102 facing the passage hole 101a has been described. 107 only needs to be arranged at a position where the Hall effect 106 occurs in the Hall element 106 by the magnetic flux generated by the permanent magnet 107, and the arrangement position can be changed as appropriate.

  Further, in the above-described embodiment, the case where the reflection type photosensor in which the reflection plate 105 is disposed at the position facing the LED 103 and the PD 104 is used as the photosensor 101 is described. It is also possible to use a photosensor in which the PDs 104 are arranged at positions facing each other.

  In the above embodiment, the case where the gaming machine according to the present invention is applied to a pachinko machine has been described. However, the present invention is applied to other gaming machines equipped with a gaming ball detection device that detects a gaming ball that has passed a predetermined area of a gaming member. It is also possible to apply. Even when the present invention is applied to such a gaming machine, the same effects as the above-described embodiment can be obtained.
