Description

  The present invention relates to a gaming machine control device used for a gaming machine such as a slot machine (synonymous with a revolving gaming machine) or a pachinko machine equipped with a gaming image display device.

A gaming machine uses a control device in which an electronic component such as an LSI is incorporated in a case. In this control device, since the inside of the case becomes hot due to the heat generated by the electronic components, a heat radiating hole is provided in the case, or a heat radiating member is installed inside the case to radiate heat to the outside (Patent Document) 1).
Japanese Patent Laid-Open No. 10-17984

  In gaming machines equipped with a game image display device such as a liquid crystal display, the display content is becoming more sophisticated and complex year by year, and it is necessary to process a large amount of data at high speed. Therefore, an image for controlling the image of the game image display device The burden on the control element is increasing. As a result, the amount of heat generated by the image control element is prominently higher than that of other electronic components, and a heat dissipation member (heat sink) dedicated to the image control element is required.

  By the way, when attaching a heat radiating member to a semiconductor element, the heat radiating member sized so as to cover the entire upper surface of the package of the semiconductor element is replaced with the upper surface of the package (the upper surface of the package if the upper surface of the package is flat, or the upper surface of the package). In the case where the mount portion protrudes, it is generally attached directly to the upper surface of the mount portion or indirectly through a heat conducting member such as silicon grease or silicon rubber. The same applies to the case where a heat radiating member is attached to an image control element which is a kind of semiconductor element. The heat radiating member sized so as to cover the entire upper surface of the image control element package is placed on the upper surface of the package (the upper surface of the package is flat). In this case, it is attached directly to the upper surface of the package, or to the upper surface of the package if the mount portion protrudes from the upper surface of the package, or indirectly through a heat conducting member such as silicon grease or silicon rubber. .

  Therefore, the control device for gaming machines requires strict checks to prevent unauthorized modification of semiconductor elements and unauthorized use of non-certified components. On the other hand, if a heat radiating member is attached to the image control element, the image control element package is covered with the heat radiating member, which makes it difficult to check the authenticity of the image control element. It should be noted that the countermeasure against fraud in which the semiconductor element is checked is a problem inherent to the control device for gaming machines, and therefore there is no problem even if the package of the semiconductor element is covered with a heat radiating member in other fields.

A metal heat dissipating member that dissipates heat in contact with the upper surface of the image control element package;
Comprising a bottom member and a lid member, sealing the bottom member and the lid member and housing the circuit board therein, and
The lid member is
A cylindrical member formed on a top plate covering the upper surface and penetrating in a tunnel shape from the inside of the case to the outside and having a length that does not contact the circuit board ;
A pair of inner flanges protruding from the inner periphery of the end of the cylindrical member with a gap between each other;
An elastic packing that is in the form of a ring that matches the inner periphery of the gap portion between the inner flanges and is loaded in the gap between the inner flanges, and
Before Symbol heat dissipation member,
A plate-like substrate that matches the inner periphery of the gap portion between the inner flanges;

Then, when the circuit board is covered with the lid member, the upper surface of the package of the image control element and the plate-like board of the heat dissipating member are in contact with each other, and the package of the image control element is operated by separating the lid member and the circuit board. Make the heat dissipation member away from the top surface,
Further, the depth of the cylindrical member and the height of the heat radiating member are set to a combination in which the heat radiating main portion of the heat radiating member does not protrude outside the lid member in the state of use when the circuit board is covered with the lid member. A gaming machine control device is provided.

In a state where the control device for gaming machines is used, the circuit board is in the case and covered with the lid member, so that the upper surface of the package of the image control element and the heat radiating member are in contact with each other. Therefore, the heat generated by the image control element is transmitted to the heat radiating member and radiated therefrom.
On the other hand, if the lid member is removed to check the circuit board for checking or the like, the heat radiating member is separated from the circuit board together with the lid member, so that the image control element package that has been covered with the heat radiating member until then is exposed. . Usually, since the name, model number, and the like of the image control element are described on the upper surface of the package, it can be easily confirmed whether the image control element is true or false. Further, after the check, since the upper surface of the image control element package and the heat dissipating member are in contact with each other simply by returning the lid member to the state in use, the workability is extremely good.

  Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of the gaming machine control device, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is a sectional view of the gaming machine control device, and FIG. 4 is a state where the bottom member and the lid member are separated. FIG. 5A is an enlarged cross-sectional view of a main part of the gaming machine control device showing another embodiment, and FIG. 5B is a game showing a state in which the bottom member and the lid member are separated from each other. It is a principal part expanded sectional view of the control apparatus for machines.

  The gaming machine control device 1 includes a circuit board 5 in a case 4 constituted by a bottom member 2 and a lid member 3. The bottom member 2 has a tray shape in which the entire periphery of the bottom plate 2a is surrounded by a low peripheral wall 2b, and the circuit board 5 is screwed at a position substantially flush with the upper end surface of the peripheral wall 2b. On the other hand, the lid member 3 has a form in which the periphery of the top plate 3a is surrounded by a downwardly suspended peripheral wall 3b, and the outer periphery of the upper end of the bottom member 2 fits exactly into the inner periphery of the lower end of the suspended peripheral wall 3b. The lid member 3 is made of a transparent synthetic resin, and has a heat radiating hole 3c, 3c,... Having a diameter of 2 mm or less (a diameter of 2 mm or less makes it difficult to insert foreign matter into the case 4). In addition, an opening 3d for projecting a connector 6 described later from the case 4 is formed. The illustrated heat radiation holes 3c, 3c,... Are formed in the hanging peripheral wall 3b of the lid member 3, but are formed in the top plate 3a or in both the hanging peripheral wall 3b and the top plate 3a. May be.

  The bottom member 2 and the lid member 3 are joined by projecting protrusions 2c and 3e on the peripheral wall 2b of the bottom member 2 and the hanging peripheral wall 3b of the cover member 3, and overlapping the protrusions 2c and 3e with a screw 7. It has a structure. Although the screw 7 of the embodiment uses a normal screw that can be removed, a one-way type sealing screw that can only be tightened may be used.

  The circuit board 5 includes an image control element 8 and a CPU 9 which are electronic components. The image control element 8 has a mount portion 8b in the center of the upper surface of the package 8a, and information that leads to identification of the image control element 8 such as a model number and a name (not shown) is described on the upper surface of the package 8a. Further, other electronic components 10, 10... And the above-described connectors 6 are mounted on the circuit board 5.

  Therefore, a heat radiating member 11 is attached to the lid member 3 of the present invention at a position facing the image control element 8 of the circuit board 5. The heat radiating member 11 is made of a metal excellent in heat conduction, and is formed by forming a pin-shaped heat radiating main portion 11b on a plate-like substrate 11a. The plate-like substrate 11a of the heat radiating member 11 is sized to cover the entire top surface of the package 8a of the image control element 8, and the top of the lid member 3 is supported by support shafts 11c, 11c. It is attached to the plate 3a. Therefore, when the cover member 3 is placed on the bottom member 2 to cover the upper surface of the circuit board 5, the heat radiating member 11 overlaps the upper surface of the package 8 a of the image control element 8 and comes into contact with the mounting portion 8 b that is one step higher. Of course, in this state, the heat of the image control element 8 is dissipated to the surroundings through the heat radiating member 11.

  In addition, the heat radiating member 11 of the embodiment is attached to the top plate 3a with an interval more than the interval between the upper surface of the package 8a of the image control element 8 and the back surface of the top plate 3a, and further detachably attached to the top plate 3a. At the same time, an elastic member is interposed between the top board 3a and the circuit board 5 to be urged.

  Specifically, while the support shaft 11c is loosely fitted to the top plate 3a, a stopper 11d for preventing the drop is attached to the end portion of the support shaft 11c to prevent the fall, and further, the plate-like substrate 11a and the top plate 3a. A spring 12 as an elastic member is interposed between the plates 3a in a compressed state. In such a configuration, since the heat radiation member 11 is pressed against the image control element 8 by the elasticity of the elastic member (spring 12), the heat radiation member 11 is in close contact with the image control element 8 and is stable, and the image control element 8 and the heat radiation member 11 are stable. Since there is no gap in the contact surface, the heat dissipation performance of the heat dissipation member 11 can be sufficiently exerted.

  5A and 5B show another embodiment in which the heat radiating member 11 is urged by an elastic member. In this embodiment, the top plate 3 a of the lid member 3 is formed with a cylindrical portion 13 that communicates with the outside of the case 4 and a cylindrical outer cylinder 14 that is slightly larger than the cylindrical portion 13 is fitted to the outside of the cylindrical portion 13. Inner flanges 13a and 14a are provided on the cylindrical portion 13 and the outer cylinder 14, respectively, so that a gap 15 is provided between the inner flanges 13a and 14a. The four sides of the substrate 11a are engaged. Even in such a configuration, the heat dissipation member 11 can be pressed against the image control element 8 by the elasticity of the rubber packing 120, and in addition, the heat of the heat dissipation member 11 is directly released outside the case 4 through the cylindrical portion 13, The temperature inside the case 4 is hard to rise. Further, as shown in FIG. 5 (a), if the heat radiating member 11 is submerged in the cylindrical portion 13 so as not to protrude out of the lid member 3, there is no trouble that the heat radiating member 11 touches the wiring on the back surface of the gaming machine. Can be prevented.

  4 and 5, reference numeral 16 denotes a support member formed on the bottom member 2 in order to prevent the circuit board 5 from being bent. The support member 16 has, for example, a cross shape in plan view, and is disposed at a position corresponding to the back side of the image control element 8. The support member 16 presses the elastic member (spring 12, rubber packing 120) applied to the image control element 8. The circuit board 5 is prevented from sinking against the pressure. In other words, if the support portion 16 that supports the back surface of the circuit board 5 is provided at a position corresponding to the image control element 8 of the bottom member 2, the heat radiation member 11 is pressed against the image control element 8 with a stronger force. Therefore, the effect by pressing the heat radiating member 11 can be further enhanced.

The gaming machine control device 1 according to the present invention is configured as described above, and is in a suitable place in a gaming machine (not shown) such as a slot machine or a pachinko machine equipped with a gaming image display device for a player. The image of the gaming image display device is controlled through the built-in image control element 8. At this time, since the circuit board 5 is in the case 4 and covered with the lid member 3, the upper surface of the package 8a of the image control element 8 and the heat radiating member 11 are in contact with each other, and therefore the heat generated by the image control element 8 is radiated. It is transmitted to the member 11 and radiated from there.
On the other hand, when the lid member 3 is removed to check the circuit board 5 for checking or the like, the heat radiating member 11 is also separated from the circuit board 5 together with the lid member 3, so that the image control element previously covered with the heat radiating member 11 is used. 8 packages 8a are exposed. Therefore, it is possible to easily check whether the image control element 8 is true or false. After the check, the upper surface of the package 8a of the image control element 8 and the heat radiating member 11 come into contact with each other simply by returning the lid member 3 to the state in use.

  As mentioned above, although embodiment of this invention was described, of course, this invention is not limited to the said embodiment. For example, in the embodiment, the heat radiating member 11 and the image control element 8 are brought into direct contact, but a heat conducting member such as silicon grease or silicon rubber may be interposed between the two. At this time, if the heat conducting member is set to adhere to the heat radiating member 11, it is convenient because the heat conducting member is peeled off from the package 8 a together when the heat radiating member 11 is separated from the image control element 8. Incidentally, if the setting is reversed, the heat conduction member covers the package 8a of the image control element 8 even if the heat radiating member 11 is separated from the image control element 8, so that the check is difficult as it is. In the embodiment, the image control element 8 and the CPU 9 are formed separately, but the image control element 8 and the CPU 9 may be integrated.

  Furthermore, although the circuit board 5 is attached to the bottom member 2 of the case 4 in the embodiment, the circuit board 5 may be attached to the lid member 3. In this case, since the relative position between the position of the connector 6 of the circuit board 5 and the opening 3d of the lid member 3 does not move, a more rigid slide system can be adopted as the coupling structure of the lid member 3 and the bottom member 2. As a result, the case 4 can be strengthened. On the other hand, when the circuit board 5 is provided on the lid member 3, the package 8a cannot be confirmed unless the circuit board 5 is further removed from the lid member 3 even if the lid member 3 and the bottom member 2 are separated. More preferably, an elastic claw is provided, the circuit board 5 is fixed with the claw, and the circuit board 5 can be easily removed by a one-touch operation to disengage the claw.
