Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more particularly to a heat dissipation technique for a board box equipped in the gaming machine.

  Conventionally, in a pachinko machine, a technique related to heat dissipation of a board box containing a circuit board is disclosed in, for example, Japanese Patent Laid-Open No. 10-17984 (Patent Document 1). In the heat dissipating technique described in the above publication, a heat dissipating member provided to release heat generated from circuit components such as a switching regulator and a transistor disposed on the circuit board to the outside is exposed to the outer surface of the substrate box. Yes.

According to the above-described conventional heat dissipation technology, the heat generated from the circuit components is transferred to the heat dissipation member by heat conduction or heat radiation, and then is released from the exposed portion of the heat dissipation member to the outside. Compared to the configuration in which the heat dissipation holes and slits are provided, the heat dissipation effect can be enhanced. However, in the above prior art, consideration is not given to the air permeability of the exposed portion of the heat radiating member exposed on the outer surface of the substrate box, and there is still room for improvement in this respect.
Japanese Patent Laid-Open No. 10-17984

  This invention is made | formed in view of this point, and it aims at providing a technique effective in improving the thermal radiation performance of a board | substrate box more in a game machine.

In order to achieve the above object, the invention described in the appended claims is configured.
According to the first aspect of the present invention, the board box that houses the circuit board on the back side of the gaming machine is stacked with other members in the front-rear direction so as to be the back side when viewed from the back side of the gaming machine. A gaming machine is configured in which a heat dissipating member for releasing heat generated inside the board box to the outside is disposed on the circuit board . Note that, as the gaming machine, a gaming machine, a slot machine, or the like that typically performs a slot game using a pachinko machine or a pachinko ball corresponds to this. The “board box” in the present invention is preferably applied to a board box that accommodates a circuit board that generates a relatively large amount of heat among board boxes provided in a gaming machine, for example, a power board box. In addition, the “other member” in the present invention corresponds to a board box different from the board box, a cover member that can be opened and closed, or a cover member that covers the back of the gaming machine.
In this invention, a heat radiating member is provided with a main body part and the heat radiating fin comprised by arrange | positioning the several blade piece extended from the side surface of the main body part in parallel by predetermined spacing. An opening for exposing the radiating fin is provided on a side surface of the substrate box, and the radiating member is disposed so as to block the opening while projecting the radiating fin from the opening to be exposed to the outside. Each wing piece of the heat radiating fin protruding from the opening extends in the vertical direction in the mounted state of the substrate box. In addition, a ball discharge port for discharging a ball discharged from the gaming machine to the facility on the island side where the gaming machine is disposed is arranged below the heat dissipation fin, and air is directed from the ball discharge port toward the heat dissipation fin. An air ventilation path for inflowing air is formed, and an outflow path for outflowing air is formed above the heat dissipating fins. Here, the “discharged sphere” corresponds to, for example, an out sphere, a safe sphere, a sphere without a sphere, or the like.

According to the present invention, since the radiating fin protrudes from the side surface of the substrate box, the heat in the substrate box can be efficiently released to the outside by the radiating fin coming into direct contact with the air outside the box. Particularly radiating fin of the present invention, while being projected on a side surface position of the substrate boxes, wing pieces constituting the heat radiation fins are configured to extend in the vertical direction. For this reason, the flow path of the air extended in the up-down direction is formed by the gap between the adjacent blade pieces, and the air easily flows along the radiation fin. That is, the air heated by the heat radiation of the radiation fins flows to the upper end side through the flow path formed between the blade pieces, and accordingly, cold air flows into the lower end side of the radiation fins. . As described above, the heat dissipation structure of the board box according to the present invention has a configuration that can promote a positive flow of air, thereby further improving the heat dissipation effect. The “extending in the vertical direction” is intended to broadly include a mode in which the extending direction of the blade pieces constituting the radiating fin has a vertical component.
As described above, in the case of a configuration in which the board box is mounted in a state where it is stacked with other members in the front-rear direction so as to be the back side when viewed from the back side of the gaming machine, particularly on the near side when viewed from the back side of the gaming machine When other members are positioned so as to cover the entire board box, it is difficult to secure a sufficiently large heat dissipation space in the front-rear direction when viewed from the back side of the gaming machine, and air flow is also generated. Since it is difficult, there is a possibility that a sufficient heat radiation effect cannot be obtained even if the heat radiation fins protrude in the side surface position of the substrate box.
However, according to the present invention, a sphere discharge port is disposed below the radiating fin exposed at the side surface position of the substrate box to form an air ventilation path through which air flows from the sphere discharge port toward the radiating fin. An outflow path through which air flows out is formed above the radiating fin. Thereby, the air warmed by the heat radiating fins efficiently flows from the bottom to the top, thereby improving the air permeability to the projected heat radiating fins and enhancing the heat radiating effect of the heat radiating fins. Moreover, it is because the ventilation path of an air can be reasonably ensured using the ball | bowl discharge | release space by arrange | positioning the ball | bowl discharge port arrange | positioned at the back surface of a game machine under the radiation fin. Further, according to the present invention, since the air discharge function for the radiating fin is given to the ball discharge port without impairing the ball discharge function, it is not necessary to make the space below the radiating fin an empty space. The back space can be used effectively.

  Hereinafter, a pachinko machine according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing the entire pachinko machine 100. The pachinko machine 100 is an example of the “game machine” in the present invention. As shown in FIG. 1, the pachinko machine 100 generally includes an outer frame 101, a main body frame 103, a game board 105, a glass frame 107, a front plate 109, and the like. The main body frame 103 is attached to the outer frame 101 via a hinge so that the left edge when viewed from the front of the pachinko machine 100 can be opened and closed. The game board 105 is attached in a state of being fitted into the main body frame 103 from the front.

  FIG. 2 is a back view of the pachinko machine. FIG. 3 is also a back view of the pachinko machine, showing a state in which the payout control board box is removed. As shown in FIG. 2 and FIG. 3, in the lower area of the opening (not shown) for mounting the game board on the back surface of the main body frame 103, a power supply board box 121 that houses a power supply board and a payout for payout device control The payout control board box 111 that accommodates the control board is mounted in a state of being stacked in the front-rear direction so that the power supply board box 121 is on the back side (front side) when viewed from the back side of the pachinko machine 100. The power supply board box 121 corresponds to the “board box” in the present invention, and the payout control board box 111 corresponds to the “other member” in the present invention.

  Further, in a lower area of the game board 105 (FIG. 2 and FIG. 3 show a back cover 105a covering most of the game board), a main control board box 113 for accommodating a main control board for controlling the whole game and A sub-control board box 115 that houses a sub-control board that drives and controls a display device, an audio device, or a lamp device based on a signal from the main control board is a front side of the main control board box 113 when viewed from the back side of the pachinko machine 100. It is mounted in a stack in the front-rear direction so as to be on the side (rear side). Note that the left end of the sub control board box 115 is slightly depicted in FIGS. 2 and 3. The board box that accommodates the various circuit boards described above consists of a box body and a box cover, and the box cover is formed of a transparent synthetic resin so that the component mounting surface of the circuit board inside the box can be seen from the outside. Has been. The mounting structure for the various substrate boxes described above is not directly related to the present invention, and thus the description thereof is omitted.

  Next, a heat dissipation structure of the power supply board box 121 that houses the power supply board 127 that generates a relatively large amount of heat compared to other control boards will be described with reference to FIGS. 6 is a perspective view showing the outer shape of the power supply board box 121, and FIG. 7 is a perspective view showing the box main body 123 with the power supply board 127 assembled and the box cover 125 in a separated state. The power supply board 127 shown in FIG. 7 is drawn with the board mounting components other than the heat dissipation member 137 and the connector terminal 141 omitted. FIG. 8 is a plan view schematically showing a state in which electrical components are mounted on the power supply board 127.

  As shown in FIG. 7, the power supply board box 121 that houses the power supply board 127 is formed of a box body 123 and a box cover 125. The power supply board 127 is attached to the box body 123, and various electric components such as a capacitor 129, a switching regulator 131, a bridge diode 133, and a line filter 135 are mounted on the power supply board 127 as shown in FIG. Yes. A metal (for example, aluminum) heat dissipation member 137 is attached to one side of the component mounting surface of the power supply substrate 127. The heat dissipating member 137 includes a main body portion 138 and heat dissipating fins 139 configured such that a plurality of blade pieces 139a extending from one side surface of the main body portion 138 are arranged in parallel at a predetermined interval. The wing pieces 139a of the radiation fins 139 extend substantially in the vertical direction (vertical direction) in a state where the power supply board box 121 is mounted on the main body frame 103. Of the electrical components, the bridge diode 133 that generates a large amount of heat is directly attached to the other side surface (the side surface opposite to the surface on which the heat radiation fins 139 are formed) of the main body 138 of the heat radiation member 137.

As shown in FIG. 7, the box cover 125 is formed in a box shape in which the mounting surface side with respect to the box main body 123 is opened, and the front edge is brought into contact with the component mounting surface side (pachinko machine rear surface side) of the power supply board 127. In this state, it is joined to the box body 123 with screws or the like, thereby covering and protecting the component mounting surface of the power supply board 162. Further, a rectangular opening 125 a for exposing the heat dissipating fins 139 of the heat dissipating member 137 to the outer surface of the box cover 125 is formed on one side surface of the box cover 125 (right side as viewed from the back side of the pachinko machine). . Therefore, in a state where the box cover 125 is joined to the box body 123, the heat dissipating fins 139 of the heat dissipating member 137 are exposed to the outside from the openings 125a of the box cover 125 as shown in FIG.
Further, the heat dissipating member 137 is fitted into the opening 125a in a state where there is almost no gap between the heat dissipating member 137 and the inner peripheral surface of the opening 125a, thereby constituting the wall surface of the power supply board box 121. For this reason, a power supply board can be protected from an unauthorized act or a collision. In the present embodiment, most of the radiating fins 139 are set so as to protrude from the side surface of the box cover 125, but the protruding amount is set appropriately.

  According to the heat dissipation structure of the power supply board box 121 configured as described above, the heat generated by the electrical components existing on the power supply board 127 is released to the outside via the heat dissipation member 137. Among the electrical components, the bridge diode 133 that generates a large amount of heat is directly attached to the heat radiating member 137, so that the heat generated by the bridge diode 133 moves to the heat radiating member 137 by heat conduction and is externally connected via the heat radiating fins 139. Is released. Further, heat generated in other electrical components moves to the heat radiating member 137 by heat radiation, and is released to the outside through the heat radiating fins 139. In other words, according to the present embodiment, the heat generated by the electrical components of the power supply board 127 can be released to the outside of the power supply board box 121 through the radiation fins 139 exposed on the outer surface of the power supply board box 121.

  In the present embodiment, the radiating fins 139 are exposed on the side surfaces of the power supply board box 121, and the blade pieces 139a of the radiating fins 139 extend in the vertical direction with the power supply board box 121 mounted on the main body frame 103. . For this reason, the space S between the adjacent blade pieces 139a forms a flow path of air extending in the vertical direction, and an air flow along the radiation fins 139 is likely to occur. That is, the air heated by heat radiation from the radiation fins 139 flows to the upper end side of the radiation fins 139 through the spaces S between the blade pieces 139a, and accordingly, cold air moves to the lower end side of the radiation fins 139. Will be actively introduced. Thus, the heat dissipation structure of the power supply board box 121 according to the present embodiment is configured to positively form air convection around the heat dissipation fins 139, thereby improving the heat dissipation effect.

  As shown in FIGS. 4 and 5, the power supply board box 121 having the heat dissipation structure as described above has the heat dissipation fins 139 on the right side and the component mounting surface on the front side (rear side) as seen from the back side of the pachinko machine 100. It is mounted on the back surface of the main body frame 103 so as to face the side. The payout control board box 111 is mounted so as to overlap the rear surface of the power supply board box 121. Generally, the payout control board has a larger board area than the power supply board 127. Accordingly, the payout control board box 111 that houses the payout control board is larger than the power supply board box 121 that houses the power supply board 127. Therefore, as shown in FIG. 2, the payout control board box 111 is viewed from the back side of the pachinko machine 100. When 111 is placed behind the power supply board box 121, a part of the payout control board box 111 is arranged in a state of protruding from the power supply board box 121. As seen from the back side of the pachinko machine 100, a ball passage component member 143 is provided on the right side of the power supply board box 121 as shown in FIG. 4. The depth dimension is set so as to be substantially flush with the rear surface. Therefore, the payout control board box 111 is mounted in a stable state across the power board board 121 and the ball path component 143.

  By disposing the power supply board box 121 as described above, the heat dissipation fins 139 of the heat dissipation member 137 exposed on the right side surface of the power supply board box 121 are attached to the power supply board box 121 as shown in FIGS. The rear surface of the mounting plate (back plate) 145, the front surface of the payout control board box 111, and the left side surface of the ball path component 143 are surrounded. As a result, it is difficult to secure a heat radiation space and the air does not flow easily.

  Therefore, in the present embodiment, as shown in FIG. 5, air flow paths (paths) are formed by forming spaces 151 and 153 communicating with the outside at the lower end and the upper end of the radiation fin 139, respectively. is doing. The upper space 151 includes an upper surface 121a of the power supply board box 121, a rear face of the main body frame 103 (specifically, a rear face 145a of the attachment plate 145 of the power supply board box 121), and a mounting base for attaching the sub control board box 115. The lower surface 147a of the 147 and the rear surface 111a of the payout control board box 111 are formed in a tunnel shape extending in the horizontal direction (left and right direction when viewed from the back side of the pachinko machine 100). That is, the upper space 151 forms a tunnel-like flow path, and the left and right sides are opened, and between the upper surface of the dispensing control board box 111 and the lower surface of the sub-control board box 115. It communicates with the rear space through a gap 155 formed in the rear. Thereby, the air above the radiation fins 139 can escape to the rear or side of the pachinko machine 100 through the gap 155 or the tunnel-shaped space 151. The tunnel-like space 151 and the gap 155 described above correspond to the “outflow path” in the present invention.

  On the other hand, the lower space 153 is configured to communicate with the lower space of the pachinko machine 100 through an out-ball discharge port 167 formed in the ball passage component 143. As shown in the cross-sectional view of FIG. 5, an out-sphere discharge passage 161 is formed in the ball passage component 143. The out ball discharge passage 161 has a predetermined upper portion (rear side) passing through an upper passage portion 163 (indicated by a broken line in FIG. 4) extending in the vertical direction and a lower side of the radiation fin 139 when viewed from the back surface of the pachinko machine 100. A lower passage portion 165 extending in length. The lower passage portion 165 of the out ball discharge passage 161 is formed in a bowl shape with the upper surface side opened, and the bottom surface is formed in a downward inclined surface toward the front side. Out ball discharge port 167 is formed on the bottom surface. The bowl-shaped opening portion of these lower passage portions 165 and the out-ball discharge port 167 are located immediately below the heat radiation fins 139.

  Thus, in the present embodiment, the lower passage portion 165 of the out sphere discharge passage 161 is formed in a bowl shape with the upper surface side opened, and the out sphere discharge port 167 is formed in the bottom surface of the rear end portion. Is positioned directly below the heat radiating fins 139 to form a ventilation passage penetrating vertically, whereby the space 153 below the heat radiating fins 139 communicates with the lower space on the back surface side of the main body frame 103. The lower space 153 communicates with the lower space on the back side of the main body frame 103 via a gap 169 between the rear end surface of the lower passage portion 165 and the front surface of the payout control board box 111. Thus, a flow path for air to flow toward the heat radiation fin 139 is secured below the heat radiation fin 139. The lower space 153, the out-ball discharge port 167, and the gap 169 correspond to the “inflow path” in the present invention.

  During the game, the out ball guided from the outlet of the out ball provided at the lower center of the game board 105 to the out ball discharge passage 161 passes through the upper passage portion 163 and the lower passage portion 165 of the out ball discharge passage 161. After flowing, it falls downward from the out-ball discharge port 167 and is collected by an island side facility (not shown).

  As described above, in the present embodiment, air passages are formed above and below the heat dissipating fins 139 for air to escape, thereby improving air permeability. For this reason, the air that has been heated by the heat radiation action of the radiation fins 139 and has flowed upward flows laterally through the upper space 151 and flows out from the side, or flows backward through the gap 155. Along with this, air flows into the lower end side of the radiating fin 139 through the out ball discharge port 167 or the gap 169 between the out ball discharge port 167 and the payout control board box 111. On the other hand, the radiation fins 139 extend in the vertical direction, and the space S between the adjacent blade pieces 139a constitutes an air flow path. Thus, a smooth and efficient air flow is formed, and the heat dissipation effect of the heat dissipation fins 139 can be improved.

  In this way, according to the present embodiment, by ensuring the air permeability of the power supply board box 121 to the heat radiation fin 139, the heat radiation effect of the heat radiation fin 139 can be improved. As a result, the payout control attached to the main body frame 103. Of the board box 111 and the power board box 121, the power board box 121 which does not have a problem even if the surface is not visually recognized can be disposed on the back side, while on the other hand, the payout control is likely to be fraudulent. The board box 111 is arranged on the front side when viewed from the back side of the pachinko machine 100 so that the surface can be visually recognized, and illegal actions such as modification and replacement of the control board can be suppressed. In addition, the two board boxes can be rationally arranged on the back surface of the main body frame 103 with a small space.

  In the present embodiment, the lower passage portion 165 positioned below the heat dissipating fins 139 is formed in a bowl shape with the upper surface opened, and the out bulb discharge port 167 is opened on the bottom surface of the lower passage portion 165. It constitutes an air passage that penetrates vertically. Thereby, the ventilation function of the air with respect to the lower end part of the radiation fin 139 can be provided to the out ball discharge passage 161 without impairing the out ball discharge function. As a result, it is not necessary to make the space below the radiation fins 139 empty, and the back space of the main body frame 103 can be used effectively.

In the embodiment described above, the pachinko machine 100 has been described. However, the present invention is not limited to the pachinko machine 100. For example, a slot machine, an arrangement ball machine, a gaming machine that uses a pachinko ball to perform a slot game, and the like. Even other game machines can be applied.
Although the present embodiment has been described by taking the power supply board box 121 as an example, it may be applied to a board box other than the power supply board box 121. In addition, the configuration in which the flow path is formed by vertically passing through the out-sphere discharge passage 161 so as to allow air to flow into the lower end portion of the radiating fin 139 is not limited to the case where the radiating fin 319 extends in the vertical direction, but the radiating fin 319. You may employ | adopt for the aspect which the fin of this extends in a horizontal direction.
In the present embodiment, the heat radiation fin 139 of the heat radiation member 137 is exposed on the right side surface of the power supply board box 121 when viewed from the back side of the pachinko machine 100, but the wall surface exposing the heat radiation fin 139 is exposed on the right side surface. The present invention is not limited to this and can be applied to a wall surface that is a vertical surface, that is, a left side surface, a front surface, and a rear surface in a state where the pachinko machine 100 is disposed on the back surface.
In the present embodiment, the case has been described in which the power supply board box 121 is formed by joining the box body 123 and the box cover 125 that are separately formed, but the box body 123 and the box cover 125 are integrally formed. It is possible to apply to the power supply board box formed.

Various aspects described below can be configured in accordance with the spirit of the present invention.
(Aspect 1)
In a gaming machine in which a board box on which a heat dissipating member that releases heat generated inside is accommodated on a circuit board to be accommodated is mounted on the back side thereof.
The heat dissipating member includes a main body part, and a heat dissipating fin configured by arranging a plurality of blade pieces extending from a side surface of the main body part in parallel at a predetermined interval.
In the side surface position of the substrate box mounted on the back side of the gaming machine, an opening for exposing the radiation fin is provided,
A gaming machine, wherein the heat dissipating member is arranged so that the opening is covered with the heat dissipating fins with each wing piece extending in the vertical direction of the mounted state of the board box.

  According to the first aspect of the present invention, a gaming machine is configured in which a board box on which a heat dissipating member that releases heat generated inside is accommodated on a circuit board to be housed is mounted on the back side. Note that, as the gaming machine, a gaming machine, a slot machine, or the like that typically performs a slot game using a pachinko machine or a pachinko ball corresponds to this. In this invention, the heat radiating member is provided with the main body part and the heat radiating fin comprised by arrange | positioning the several blade piece extended from the side surface of the main body part in parallel by predetermined spacing. In addition, an opening for exposing the radiating fin is provided at the side surface position of the board box mounted on the back side of the gaming machine, and each wing piece is extended in the vertical direction of the mounted state of the board box so as to close the opening with the radiating fin. In addition, the heat dissipating member is arranged. Here, the “board box” in the present invention is preferably applied to a board box that accommodates a circuit board with relatively large heat generation, for example, a power board box, among board boxes provided in a gaming machine. It does not preclude application to a control board box that houses a board.

  According to the present invention, since the radiating fin is exposed from the substrate box, the heat in the substrate box can be efficiently released to the outside by the radiating fin being in direct contact with the air outside the box. In particular, the heat dissipating fin in the present invention is exposed at the side surface position of the substrate box, and the blade pieces constituting the heat dissipating fin extend in the vertical direction. For this reason, the flow path of the air extended in the up-down direction is formed by the gap between the adjacent blade pieces, and the air easily flows along the radiation fin. That is, the air heated by the heat radiation of the radiation fins flows to the upper end side through the flow path formed between the blade pieces, and accordingly, cold air flows into the lower end side of the radiation fins. . As described above, the heat dissipation structure of the board box according to the present invention has a configuration that can promote a positive flow of air, thereby further improving the heat dissipation effect.

(Aspect 2)
“A gaming machine according to aspect 1,
In the structure in which the board box is stacked in the horizontal direction with other members and arranged on the back side when viewed from the back side of the gaming machine, each wing piece is mounted on the side surface of the board box in a mounted state of the board box An inflow path for allowing air to flow into the lower end portion of the radiating fin is formed on the lower end portion side of the radiating fin exposed as extending in the vertical direction of the radiating fin. A gaming machine, characterized in that an outflow path through which air flows out from an upper end portion is formed. "

  According to the invention described in Aspect 2, in the structure in which the board box in the gaming machine described in Aspect 1 is disposed in the back side when viewed from the back side of the gaming machine in a state where it is stacked horizontally with other members. An inflow path for allowing air to flow into the lower end portion of the radiating fin is formed on the side surface position of the radiating fin at the side surface position of the radiating fin that is exposed in the direction in which each blade piece extends in the vertical direction of the mounting state of the substrate box. In addition, an outflow path through which air flows out from the upper end portion of the radiating fin is formed on the upper end side of the radiating fin. Here, “another member arranged in a state of being laminated in a horizontal direction with respect to the board box” is an openable / detachable cover for covering a board box different from the board box or the back of the gaming machine. This applies to members and the like.

As described above, when the board box is arranged in a state of being stacked horizontally with other members and the board box is arranged on the back side when viewed from the back side of the gaming machine, particularly when viewed from the back side of the gaming machine. When other members located on the front side are arranged so as to cover the entire board box, it is difficult to secure a sufficiently large heat dissipation space in the front-rear direction when viewed from the back side of the gaming machine. Since the flow is difficult to occur, even if the heat dissipation member is exposed at the side surface position of the substrate box, there is a possibility that a sufficient heat dissipation effect cannot be obtained.
According to the present invention, an inflow path through which air flows into the lower end portion of the radiating fin is formed on the lower end portion side of the radiating fin, and air is supplied from the upper end portion of the radiating fin to the upper end side of the radiating fin. Since the outflow path for the outflow is formed, the air easily flows in combination with the plurality of blade pieces constituting the radiating fin extending in the vertical direction. In other words, since the air permeability to the heat radiating fins can be improved, the heat radiating effect from the heat radiating fins can be enhanced even in a situation where a sufficiently large heat radiating space cannot be secured on the front, rear, left and right of the heat radiating fins It becomes.

That is, in the present invention, among the control board box and the power supply board box arranged on the back side of the gaming machine, the control board box that is prone to cheating is viewed from the back side of the gaming machine so that the surface can be seen. The power supply board box that is arranged on the front side and has no problem even if the surface is not visually recognized is arranged on the back side as viewed from the back side of the gaming machine. Thus, for the control board box, it is possible to secure the visibility and suppress unauthorized actions such as modification and replacement of the control board, and for the power supply board box that does not make the visibility a problem, a heat dissipation effect is secured, Reasonable placement is achieved. In addition, since the two board boxes are arranged in a stack when viewed from the back side of the gaming machine, it can be mounted on the back side of the gaming machine in a small space.

  According to the invention described in aspect 4, in the gaming machine described in any one of aspects 1 to 3, the ball discharged from the gaming machine is disposed below the heat dissipating fin on the island side where the gaming machine is disposed. In addition, a ball discharge port for discharging air to the facility is arranged, and an air ventilation path penetrating in the vertical direction for allowing air to flow toward the heat radiating fin is formed at or near the discharge ball discharge port. . Here, the “discharged sphere” corresponds to, for example, an out sphere, a safe sphere, a sphere without a sphere, or the like. In addition, as a mode of “penetrating vertically”, a configuration in which a ball discharge passage is typically formed in a bowl shape with an open upper surface and a ball discharge port for dropping a ball on the bottom surface (lower surface) corresponds to this. However, an embodiment in which the ball discharge passage is preferably formed in a cylindrical shape in which upper and lower surfaces are provided with ventilation slits or holes. According to the present invention, since the air discharge function for the radiating fins is given to the sphere discharge passage without impairing the sphere discharge function, it is not necessary to make the space below the radiating fins an empty space. Space can be used effectively.

According to the invention described in aspect 5, the board box that accommodates the circuit board is mounted on the back surface of the gaming machine in a state of being stacked with other members in the front-rear direction so as to be the back side when viewed from the back side of the gaming machine. In addition, a gaming machine in which a heat dissipating member for releasing heat generated inside the board box to the outside is arranged on the circuit board. Note that, as the gaming machine, typically, a pachinko machine or a gaming machine that performs a slot game using a pachinko ball corresponds to this. In addition, “another member arranged in a state of being stacked in the front-rear direction with respect to the board box” is an openable / detachable cover member for covering a board box different from the board box or the back of the gaming machine. This is the case.
In this invention, the heat radiating member is provided with the main body part and the heat radiating fin comprised by arrange | positioning the several blade piece extended from the side surface of the main body part in parallel by predetermined spacing. In addition, an opening for exposing the radiation fin is provided at the side surface position of the board box mounted on the back side of the gaming machine, and a radiation member is disposed so as to close the opening with the radiation fin, and further below the radiation fin. The ball discharge port for discharging the ball discharged from the gaming machine to the facility on the island side where the gaming machine is arranged is arranged, and air is caused to flow toward the heat radiating fin at or near the ball discharge port. It is set as the structure which formed the ventilation path of the air penetrated to an up-down direction.

As described above, in the case of a configuration in which the board box is mounted in a state where it is stacked with other members in the front-rear direction so as to be the back side when viewed from the back side of the gaming machine, particularly on the near side when viewed from the back side of the gaming machine When other members are positioned so as to cover the entire board box, it is difficult to secure a sufficiently large heat dissipation space in the front-rear direction when viewed from the back side of the gaming machine, and air flow is also generated. Since it is difficult, even if the heat radiation fin is exposed at the side surface position of the substrate box, there is a possibility that a sufficient heat radiation effect cannot be obtained.
However, according to the present invention, the ball discharge port is disposed below the heat radiating fin exposed at the side surface position of the substrate box, and an air ventilation path penetrating in the vertical direction is formed at or near the ball discharge port. Thus, the air permeability to the exposed heat radiating fin is improved, and the heat radiating effect of the heat radiating fin can be enhanced. By arranging the ball outlet located on the back side of the gaming machine below the heat dissipating fin, it is possible to reasonably secure the air passage that penetrates in the vertical direction using the ball discharge space. It is.
