Description

  The present invention relates to a gaming machine detection switch (hereinafter simply referred to as a detection switch) used in a gaming machine such as a pachinko machine.

  A pachinko machine, which is one of the gaming machines, has various winning devices attached to the game board, and each winning device has a detection switch for detecting the winning of a game ball to each winning device. It is attached. FIG. 4 shows a conventional detection switch. The detection switch 51 is provided with a game ball passage hole 53 for passing a winning ball at one end edge of the main body 52. A detector 58 for detecting the passed game ball is incorporated behind the game ball passage hole 53 so as to be adjacent to the wall surface of the game ball passage hole 53. In addition, an external terminal plate 54 for connecting to another electronic device is projected on the edge opposite to the game ball passage hole 53, and a detector 58 and an electric terminal are connected to the back surface of the external terminal plate 54. The metal layers 55 and 55 which are connected to each other are laminated. The detection switch 51 has a gaming board surface of the gaming machine in a state where the metal layers 55 and 55 of the external terminal board 54 are connected to lead wires 56 and 56 for input to other electronic devices by solder 57 or the like. It is installed on the back side of the game and used inside the winning device. The detection switch 51 applies a constant voltage to the metal layers 55 and 55 while the power is supplied to the gaming machine. When the gaming ball passes through the gaming ball passage hole 53, the passing of the gaming ball is performed. Due to the change in the magnetic flux density around the detector 58, the potential difference between the two metal layers 55, 55 decreases (that is, the voltage decreases). For this reason, in the pachinko machine in which the detection switch 51 is installed, the game ball can be detected by detecting the decrease in the voltage.

  Hereinafter, an example of the detection switch of the present invention will be described in detail with reference to the drawings.

  1 and 2 show a detection switch, and a main body 2 of the detection switch 1 is made of a synthetic resin and is formed into a flat rectangular parallelepiped shape. A game ball passage hole 3 having a substantially octagonal column shape is formed at one end of the main body 2, and behind the game ball passage hole 3, it is adjacent to the wall surface of the game ball passage hole 3. A proximity sensor 22 as a detector is incorporated. Further, an external terminal plate 4 made of a synthetic resin protrudes from the other end edge of the main body 2 and is substantially parallel to the upper surface of the main body 2. Further, metal layers (external output terminals) 5 a and 5 b electrically connected to the proximity sensor 22 are laminated on the lower surface of the external terminal plate 4. Positioning ribs 7 and 7 are provided vertically on both the left and right sides of the main body 2.

  Furthermore, a cover member 6 composed of an upper member 6 a and a lower member 6 b made of synthetic resin is attached to the external terminal plate 4, and covers the outer periphery of the external terminal plate 4. In the upper member 6 a, downward side plates 9 and 9 are extended on the left and right sides of the upper plate 8. And the notch parts 11 and 11 are provided in the right-and-left both ends of each side plate 9 and 9, and the insertion hole 10 is drilled at the lower end.

  On the other hand, the lower member 6 b has a substantially rectangular parallelepiped shape, and is greatly recessed from the center to the rear end, forming a concave portion 15. Then, the two metal terminals 17a and 17b protrude from the inner surface of the front plate 14 in parallel toward the rear. Further, the upper end surfaces of the side plates 12 and 12 are in a state where the grounding portions 16a and 16b electrically connected to the metal terminals 17a and 17b are exposed. Further, fitting protrusions 13a, 13a, and 13b are provided so as to protrude from the upper ends of the left and right sides of the outer surfaces of the side plates 12 and 12 and the lower end of the center, respectively.

  In the upper member 6a and the lower member 6b as described above, the upper surface of the lower member 6b is brought into contact with the lower surface of the external terminal plate 4, and the ground portions 16a and 16b are respectively connected to the metal on the lower surface of the external terminal plate 4. In the state of being in contact with the layers 5a and 5b, the elasticity of the side plates 9 and 9 of the upper member 6a is used to fit the notches 11 and 11 and the insertion holes 10 of the side plates 9 and 9, respectively. By fitting the mating protrusions 13a, 13a, and 13b, the upper member 6a and the lower member 6b are integrated to sandwich the external terminal plate 4. The integrated cover member 6 has a concave connector shape in which only the rear surface is opened (that is, the two metal terminals 17a and 17b protrude to the opening of the rear surface in the concave portion 15 closed up and down and left and right. Shape). Further, the metal terminals 17a and 17b are in a state of being electrically connected to the proximity sensor 22 via the metal layers 5a and 5b and the ground portions 16a and 16b.

  In the detection switch 1 configured as described above, an input terminal (convex connector) 18 of another electronic device is inserted into the concave portion 15 from the rear surface of the integrated cover member 6 as shown in FIG. The two metal terminals 17a and 17b that are positioned are electrically connected to the lead wires 21a and 21b of the input terminal 18, and are installed on the back of a game board of a gaming machine such as a pachinko machine, It is used by being installed inside. In addition, when installing the detection switch 1, the positioning ribs 7 and 7 can be used to accurately install the detection switch 1. The detection switch 1 applies a certain voltage to the metal terminals 17a and 17b while the power is supplied to the gaming machine, and when the gaming ball passes through the gaming ball passage hole 3, the gaming ball passes along. Thus, the magnetic flux density around the proximity sensor 22 changes, and the change in the magnetic flux density reduces the potential difference between the two metal terminals 17a and 17b (that is, the voltage decreases). For this reason, in a gaming machine such as a pachinko machine in which the detection switch 1 is installed, a game ball can be detected by detecting a decrease in the voltage.

  The detection switch 1 is configured as described above, and the external output terminals (the metal layers 5a and 5b) are covered with the cover member 6 (the upper member 6a and the lower member 6b), and thus the external output terminals 5a and 5b. It is possible to effectively prevent an illegal act of attaching an illegal substrate to the board. Further, the connector shape of the cover member 6 can be used to easily connect to a connector (such as the input terminal 18) that is an input terminal of another electronic device. Furthermore, malfunctions are not caused by static electricity from other electronic devices. In addition, since the detection switch 1 has a concave connector shape in which only the rear surface of the cover member 6 is opened, the detection switch 1 is highly versatile and can be connected to many other electronic devices having a convex connector. In addition, it is difficult to cause poor connection, and in addition, the structure of the cover member 6 is simple and hardly damaged.

  Furthermore, since the cover member 6 is detachably attached to the detection switch 1, the cover member 6 can be easily installed when installed in a place where an illegal substrate is unlikely to be attached, such as inside a winning device. It can be removed and installed compactly without requiring a large space.

  For example, the cover member is not necessarily limited to one that is separated into two upper and lower members, and an upper member that is integrally opened on the upper portion of the lower member, or an insertion hole for inserting an external terminal plate is provided. The provided bottomed cylindrical shape etc. may be sufficient and the shape will not be specifically limited if it covers an external output terminal.

  Furthermore, the cover member is not limited to a member that is detachably attached to the external output terminal, but may be a member that is fixed to the external output terminal, such as a member in which a grounding portion is soldered to a metal layer of the external output terminal. In addition, when the cover member is a member in which the grounding portion is soldered to the metal layer of the external output terminal, the contact state between the detector and the metal terminal of the cover member is good even when the gaming machine receives vibration. There is an advantage that it is kept. In addition, the cover member is not limited to having a concave connector shape, and may have a convex connector shape.

  Also, the game ball passage hole does not need to be provided at the edge of the main body part, and can be provided at the center of the main body part, and the shape thereof is not limited to an octagonal shape, and other shapes such as a cylindrical shape It can also be changed.

  Furthermore, the detector provided in the game ball passage hole is not limited to a non-contact type sensor using a permanent magnet, but a non-contact type sensor using an optical sensor, or a game ball passing through the game ball passage hole. A contact type that performs a grounding operation may be used, and the shape and structure thereof are not particularly limited as long as the passing of the game ball is converted into an electric signal.
