Description

  The present invention relates to a gaming machine such as a pachinko machine, an arrangement ball machine, a slot machine, and the like, and when cooling air is sucked into the board housing chamber in the board case by sucking air outside the board case and cooling the heat sink. It is designed to avoid entering as much as possible.

  In gaming machines, such as pachinko machines, special symbol starting means, normal winning means, big winning means, etc. are mounted in the gaming area of the game board, and image display means such as liquid crystal display means are provided in the approximate center of the gaming area. A variety of effect images are displayed on the image display section of the image display means in accordance with changes in the gaming state by special symbol starting means, normal winning means, big winning means, and the like. The main control board for controlling the game operation by the special symbol starting means, the normal winning means, the big winning means, etc., and the image control board for controlling the effect image displayed on the image display means are accommodated in respective board cases. It is mounted on the back side of the game board.

  Recent pachinko machines tend to employ high-resolution image display means and use LSIs and other electronic components with high processing capabilities to process image information at high speed. On the other hand, when an LSI or other electronic component having a high processing capacity is adopted, it is necessary to prevent overheating due to the heat generation. Therefore, a heat sink for heat dissipation that abuts an electronic component that easily generates heat and a cooling fan that cools the heat sink with cooling air are provided to forcibly cool the electronic component.

  In mounting the heat sink and the cooling fan, conventionally, the heat sink and the cooling fan are stacked and fixed on the board in the board case in front and back (Patent Document 1), and both the front and back sides of the case body of the board case, There is one (Patent Document 2) in which a heat sink and a cooling fan are overlapped and fixed in front and back so as to sandwich the case body from both sides.

  For example, in the former mounting form, a heat sink that contacts the electronic components of the board is fixed to the board with mounting pins or the like, and a cooling fan is fixed on the heat sink with mounting screws. In the latter mounting form, a cooling fan is fitted into the recessed portion on the outer side of the case body, and a heat sink that faces the cooling fan is sandwiched between the bottom wall of the recessed portion on the inner side of the case body. It is fixed to.

  All of the conventional cooling and heat dissipation methods are formed on the surface of the substrate case after the outside air is sucked into the substrate case through the air intake by the cooling fan, and the cooling air is blown to the heat sink in the substrate case to cool it. In addition, air is exhausted from a large number of exhaust ports to the outside of the substrate case.

  In this way, the cooling air blown onto the heat sink diffuses over almost the entire area of the board case and is then exhausted from a number of exhaust ports, so that not only the heat sink can be cooled, but the heat generated by other electronic components. This has the advantage of preventing hot air from being accumulated in the substrate case.

  However, since the air outside the board case is directly sucked and blown to the cooling fan, dust, iron powder, etc. are sucked into the board case together with the intake air, and the dust, iron powder, etc. are applied to the surface of the board, electronic parts, etc. There is a risk of adhesion. Especially in the case of pachinko machines, game balls are used as game media. When installed on the island of the game hall, a large amount of game balls circulate between the ball supply equipment on the island side and the pachinko machines. Therefore, it is in an environment in which dust due to circulation of game balls, especially metal powder is likely to be generated. Therefore, in the conventional method in which the cooling air sucked from the outside is directly blown onto the heat sink, dust and metal powder outside the substrate case are sucked and adhered to the surface of the substrate, and the printed wiring formed on the surface of the substrate is removed. There are problems such as short circuit.

  In view of such conventional problems, the present invention cools the heat sink by sucking cooling air from the outside of the substrate case by a cooling fan, but the cooling air does not enter the substrate accommodation chamber in the substrate case as much as possible. An object of the present invention is to provide a gaming machine that can prevent dust from adhering to the substrate in the substrate housing chamber.

  The present invention accommodates a substrate 38 on which a heat-generating electronic component 37 is mounted in a substrate case 27, a heat sink 39 that dissipates heat from the electronic component 37, and a cooling fan 40 that sends cooling air to the heat sink 39. In the gaming machine including the board case 27, the cooling passage 73 having both ends communicating with the cooling air intake port 84 and the exhaust port 85 of the board case 27 is separated from the board housing chamber 74 in the board case 27. 27, and the heat sink 39 and the cooling fan 40 are provided in the cooling passage 73.

  According to the present invention, while cooling air is sucked from the outside of the substrate case 27 by the cooling fan 40 and the heat sink 39 is cooled, the cooling air can be prevented from entering the substrate housing chamber 74 in the substrate case 27 as much as possible. There is an advantage that dust can be prevented from adhering to the substrate 38 in the substrate accommodating chamber 74.

The heat in the substrate housing chamber 74 due to heat generated from the electronic components is radiated by natural convection. The cooling fan 40 is connected to the first control board 43 or the second control board 44 via a harness, a connector, etc., not shown.

  In this embodiment, when assembling the image control board case 27, the cooling fan 40 is first inserted and fixed in the second housing portion 71 of the mounting base 41, and then in the first housing portion 70 of the mounting base 41. The heat sink 39 is inserted. At this time, the heat sink 39 is inserted into the first accommodating portion 70 from the fin 67 side, and the fins 67 at both upper and lower ends are fitted between the sandwiching walls 79 and positioned by the heat sink 39 in the first accommodating portion 70.

  As a result, the main body portion 66 of the heat sink 39 is accommodated between the left and right wall portions 70b of the first housing portion 70, and the fins 67 on both the upper and lower sides of the heat sink 39 are provided on the upper and lower sides between the partition wall 77 and the main body portion 66. In spite of the presence of the opening 75 on the front side of the first accommodating part 70, the opening 75 side of the first accommodating part 70 can be substantially closed by inserting and positioning the heat sink 39 in the first accommodating part 70. it can.

  Thereafter, the positioning protrusion 48 of the mounting base 41 is inserted into the positioning hole of the first control board 43 so that the main body 66 of the heat sink 39 in the first housing part 70 corresponds to the electronic component 37 of the first control board 43. Next, after positioning the mounting base 41 with respect to the first control board 43, the mounting screws 49 are screwed into the mounting bosses 47 from the first control board 43 side to fix the mounting base 41 to the first control board 43. .

  Next, after the second control board 44 is attached in the first case body 33, the first control board 43 is attached in the first case body 33. When attaching the first control board 43, first, the positioning projection 47a of the first case body 33 is inserted into the positioning hole of the first control board 43, and the second accommodating portion 71 and the cooling duct 72 of the attachment base 41 are connected to the first control board 43. The first control board 43 is positioned with respect to the first case body 33 so as to be fitted to the first fitting portion 82 and the second fitting portion 83 of the back wall portion 53 of the one case body 33, respectively.

  As a result, the intake port 84 of the first case body 33 communicates with the housing 62 of the cooling fan 40 and the exhaust port 85 of the first case body 33 communicates with the cooling passage 73 in the cooling duct 72. The first control board 43 may be fixed to the first case body 33 by screwing the mounting screw 49 into the mounting boss 47 from the first control board 43 side.

  Accordingly, since the heat sink 39 and the cooling fan 40 can be integrally fixed to the first control board 43 in advance through the mounting base 41 in this way, the first control board 43, the heat sink 39 and the cooling fan 40 are combined into one. It becomes possible to handle as a unit, and the work can be easily and efficiently performed as compared with the case where the first case body 33 is individually incorporated. Further, since the first control board 43, the heat sink 39, and the cooling fan 40 can be handled as one unit, there is an advantage that component management can be easily performed.

  After fixing the first control board 43 in the first case body 33, the first case body 33 and the second case body 34 are coupled to each other in a closed state via the engaging means 35 and the sealing means 36. That's fine.

  In this embodiment, during operation of the pachinko machine, the cooling fan 40 is always operated, outside air is sucked into the cooling passage 73 from the intake port 84, and the heat sink 39 is cooled by the cooling air flowing in the cooling passage 73. Although the first control board 43 has the heat-generating electronic component 37, the electronic component 37 can be forcibly cooled by the cooling air via the heat sink 39. Overheating can be prevented.

  That is, when the cooling fan 40 is activated, the air outside the image control board case 27 is sucked into the first accommodating portion 70 through the air inlet 84, and the cooling air is blown to the fins 67 of the heat sink 39. The electronic component 37 can be forcibly cooled by the air via the heat sink 39. The cooling air that has collided with the main body 66 of the heat sink 39 and absorbed heat from the fins 67 is divided into left and right cooling ducts 72 along the fins 67, and then passes through the cooling duct 72 to the outside from the exhaust port 85. And go exhausted.

  Accordingly, the cooling air sucked into the cooling passage 73 from the intake port 84 passes from the exhaust port 85 to the outside of the image control board case 27 through the cooling passage 73 separated from the substrate housing chamber 74 in the image control board case 27. Therefore, even in an environment where dust containing iron powder or the like is likely to be generated, it is possible to prevent the dust containing iron powder or the like sucked together with the cooling air from entering the substrate storage chamber 74 in advance. Adhesion to the surfaces of the control substrates 43 and 44 can be suppressed as much as possible.

  In addition, the first control board 43 on which the electronic component 37 is mounted is accommodated in the image control board case 27, and the heat sink 39 for radiating the electronic component 37 and the cooling fan 40 for cooling the heat sink 39 are assembled. A mounting base 41 in which the heat sink 39 is accommodated in the first accommodating portion 70 and the cooling fan 40 is accommodated in the second accommodating portion 71 is provided on the first control board 43, and the heat sink 39 and the cooling fan 40 are fixed via the attaching base 41. Therefore, the first control board 43, the heat sink 39, and the cooling fan 40 can be unitized as one unit, and subsequent assembly / disassembly, other handling, and component management can be easily performed.

  Since the heat sink 39 is interposed between the first control board 43 and the mounting base 41 via the electronic component 37 and the cooling fan 40 is disposed between the mounting base 41 and the first case body 33, the heat sink 39, the arrangement of the cooling fan 40 with respect to the mounting base 41 is easy, and the heat sink 39 can be easily assembled in a state where the cooling fan 40 is in contact with the electronic component 37 on the first control board 43.

  Further, when the first control board 43 is fixed in the first case body 33 when the image control board case 27 is assembled, the second housing portion 71 of the mounting base 41 and the cooling duct 72 on the opposite side to the first control board 43. Since the front end fits and contacts the first fitting portion 82 and the second fitting portion 83 of the first case body 33, the first control board 43, the heat sink 39 and the cooling fan 40 are unitized via the mounting base 41. Nevertheless, the heat sink 39 and the cooling fan 40 in the first case body 33 can be easily and reliably supported via the mounting base 41.

  While the mounting base 41 includes a corresponding first storage portion 70 and a second storage portion 71 in a reverse opening shape, the mounting base 41 includes a cooling passage 73 extending from the first storage portion 70 to both sides of the second storage portion 71. Since the first case body 33 is provided with an intake port 84 that communicates with the cooling passage 73 on the cooling fan 40 side and an exhaust port 85 that communicates with the cooling passages 73 on the left and right sides of the heat sink 39, the mounting base 41 can be downsized. The heat sink 39 and the cooling fan 40 can be easily arranged in the cooling passage 73.

  Since the mounting base 41 is provided with pressing means 80 that presses the heat sink 39 in the first housing part 70 toward the electronic component 37, even if the heat sink 39 is fitted and housed in the first housing part 70, The heat sink 39 can be reliably brought into contact with the electronic component 37, and the heat sink 39 can be easily attached to the mounting base 41.

The first case body 33 is formed with an exhaust port 85 on the cooling fan 40 side of the cooling passage 73 and an intake port 84 on the cooling passage 73 side of the cooling duct 72. Other configurations are substantially the same as those of the first embodiment.

  In this case, the cooling air sucked from the intake port 84 through the left and right cooling ducts 72 is merged when passing through the heat sink 39 of the first housing portion 70, and then the communication port 76 of the partition wall 77, 2 Exhaust from the exhaust port 85 to the outside through the cooling fan 40 of the housing portion 71. Therefore, even if an exhaust type is used for the cooling fan 40, the heat sink 39 can be cooled by the cooling air flowing through the cooling passage 73, and can be implemented in the same manner as in each embodiment.

  When the exhaust fan is used as the cooling fan 40, the cooling fan 40 can be disposed not only in the reverse direction of the cooling air but also in the vicinity of the exhaust port 85 of the cooling passage 73. The dust in the cooling air can be prevented from entering the substrate housing chamber 74 without completely closing the opening 75 of the first housing portion 41 of 41. It is also possible to promote ventilation in the substrate storage chamber 74 by exhausting part of the air in the substrate storage chamber 74 by the cooling fan 40.

  FIG. 14 illustrates a fourth embodiment of the present invention. In this embodiment, the mounting base 41 has a flat shape in which a first housing part 70 for housing the heat sink 39 and a second housing part 71 for housing the cooling fan 40 are formed along the surface direction of the first control board 43. In this case, it is detachably fixed to the first control board 43 via an attachment boss 47, a positioning projection 48, an attachment screw 49 and the like.

  A cooling passage 73 is formed in the mounting base 41 in a flat shape along the first control board 43 so that both ends thereof communicate with the intake port 84 and the exhaust port 85 of the first case body 33. A first accommodating portion 70 and a second accommodating portion 71 are provided.

  In the first housing part 70, a pressing means 80 is disposed between the heat sink 39 and the bottom wall part 70c. The pressing means 80 is formed by cutting and bending a metal plate such as a leaf spring, but may have another structure. The mounting base 41 is configured by detachably coupling a first mounting base 41a and a second mounting base 41b. The first case body 33 is provided with a first fitting portion 82, an exhaust port 85, a second fitting portion 83, and an intake port 84. Other configurations are substantially the same as those of the first embodiment.

  In this case, a cooling passage 73 is formed in the flat mounting base 41, and a first housing portion 70 for the heat sink 39 and a second housing portion 71 for the cooling fan 40 are provided in the cooling passage 73. ing. It is also possible to unitize the heat sink 39, the cooling fan 40, and the first control board 43 using such a mounting base 41.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the embodiment, the image control board case 27 is exemplified as the board case. However, various substrate other than the image control board case 27 may be used as long as the board case accommodates the control board on which the heat generating electronic component 37 is mounted. The same can be applied to the substrate case. In addition to being mounted vertically in the vertical mounting location, the board case may be mounted horizontally in the vertical mounting location, or mounted in the front-rear or left-right direction on the upper or lower surface of the horizontal mounting location. Also good.

  The substrate case is usually configured by connecting the first case body 33 and the second case body 34 so as to be openable and closable, but may be a combination of three or more case bodies, or in the case of a substrate case in which one side is open. If so, it may be constituted by one case body. Moreover, although the 1st control board 43 and the 2nd control board 44 are accommodated in the board | substrate case, an internal control board may be one and three or more may be sufficient as it.

  The exothermic electronic component 37 is generally a semiconductor element such as an LSI, but may be other than the semiconductor element. In addition, if the heat-generating electronic component 37 is a semiconductor element such as an LSI having a rectangular shape, a rectangular heat sink 39 corresponding to the shape of the electronic component 37 is used. However, the heat sink 39 is not necessarily rectangular. The one having an appropriate shape may be used in accordance with the shape of the electronic component 37.

  The mounting base 41 may be fixed to the first control board 43 or may be attached to the inside of the board case, such as the inside of the first case body 33. The pressing means 80 provided between the heat sink 39 and the first housing portion 70 may be integrated with the first housing portion 70 or may be configured by bending an elastic wire or the like. However, it is desirable not to disturb the flow of cooling air between the fins 67. . The cooling fan 40 in the second housing portion 71 may be sandwiched and fixed between the case body 33 and the attachment 41st.

  If the 1st accommodating part 70 and the 2nd accommodating part 71 are arrange | positioned facing the axial center direction of the rotating shaft of the cooling fan 40, and if it arrange | positions in arbitrary directions, such as arranging in the plate | board surface direction of the 1st control board 43, it will be. Good. The mounting base 41 only needs to have a structure in which the first housing portion 70 and the second housing portion 71 are arranged in the middle of the cooling passage 73. Further, both ends of the cooling passage 73 communicate with the intake port 84 and the exhaust port 85 formed in the first case body 33, but the cooling passage 73 may be provided so as to circulate in the substrate case.

  The cooling ducts 72 may be provided on both the upper and lower sides of the first housing part 70 in accordance with the direction of the fins 67. Further, in the case of the heat sink 39 having a large number of pin-like projections instead of the fins 67, the cooling duct 72 may be provided in a cross shape in the vertical and horizontal directions, or one side in the vertical direction and one in the horizontal direction. It may be provided on the side. Further, the cooling duct 72 may be provided only on one side of the left and right or the top and bottom. Therefore, it is sufficient that the cooling duct 72 is on at least one side of the first accommodating portion 70.

  Furthermore, although the embodiment illustrates the case where the present invention is applied to a pachinko machine, it can be similarly applied to various game machines including a slot machine as well as a ball game machine such as an arrange ball machine. Needless to say.
