As described above, gaming machines such as pachinko machines are provided with various control devices such as a main control device that performs overall control of games and a display control device that controls a display device for performing display effects. ing.

Conventionally, in these control devices, since electronic components such as a central processing unit (CPU) are accompanied by heat generation, heat generated from the electronic components can be efficiently released, for example, by providing a heat radiating hole in a substrate box that accommodates the control substrate. Various heat dissipation measures are taken.

In recent years, due to diversification of presentation functions, higher performance electronic components such as a CPU having a high processing speed have been mounted on the control board. For example, a display control board that controls a liquid crystal display device and the like is equipped with a CPU, an image processing device (VDP), and the like that have a high processing speed, thereby enabling various display effects.

In general, when the processing speed of the CPU or the like, that is, the operation clock frequency is increased, the power consumption is increased and the amount of generated heat is also increased. When a large amount of heat is generated in the substrate box in this way, the heat dissipation holes alone cannot sufficiently release the heat, and the control device may malfunction due to the heat generated by the electronic components. . Therefore, in recent control devices equipped with high-performance electronic components, more efficient heat dissipation measures such as mounting a blower such as a cooling fan are required (see, for example, Patent Document 1).

However, when arranging the blower in the board box, in addition to the work of assembling the control board or the like in the board box with a little space for placement, new work such as the work of assembling the blower is added. . Furthermore, after assembling the blower to the board box, it is necessary to connect the power supply wiring of the blower to the control board or the like in the narrow space. For this reason, the assembly of the blower device may significantly reduce the working efficiency when assembling the substrate box.

Such a problem is not limited to pachinko machines, but also applies to other gaming machines such as slot machines equipped with various control devices.

The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide a gaming machine capable of improving the workability of assembling a blower.

  As shown in FIGS. 14 and 15, the mounting plate 670 becomes a substantially flat plate substrate 751 serving as a mounting base for mounting on the display control board 650, and a holding section and a frame section for holding the cooling fan 675. Holder part 752.

  The plate substrate 751 has a vertically long rectangular shape, the length of the long side is set to be equal to the vertical length of the display control board 650, and the length of the short side is about 3 minutes of the left and right length of the display control board 650. Is set to about 1.

  Support leg portions 753 are formed on both the upper and lower sides of the plate substrate 751 so as to extend in the direction of the back side of the plate, that is, in the direction of attachment to the display control substrate 650. The support leg portion 753 constitutes a support portion in the present embodiment.

  Further, one locking piece 754 as a locking portion is formed on each of the upper and lower sides of the plate substrate 751 on each of the left and right sides of the support leg 753. Each locking piece 754 is formed to extend toward the back surface side of the plate substrate 751, similarly to the support leg portion 753.

  The extending length of the locking piece 754 is slightly longer than the extending length of the support leg 753, and a locking claw 754 a that protrudes inward in the vertical direction of the plate substrate 751 is formed at the tip of each locking piece 754. Is formed.

  In addition, positioning protrusions 755 that extend further than the support legs 753 are formed on the support legs 753 on both the upper and lower sides. However, the formation position of each protrusion 755 is different between the upper and lower sides. In the lower side portion, the protruding portion 755 is formed at a substantially central portion in the left-right direction, whereas in the upper side portion, the protruding portion 755 is formed slightly to the left when viewed from the surface side of the mounting plate 670. This is to prevent the attachment plate 670 from being attached upside down when the attachment plate 670 is attached to the display control board 650 as will be described later.

  Corresponding to the locking pieces 754 and the protrusions 755, notched concave portions 757 and 758 are formed in the upper edge portion 650 c and the lower edge portion 650 d of the peripheral edge portion of the display control board 650.

The left auxiliary leg portion 760 when viewed from the front surface side of the mounting plate 670 is provided at a position slightly below the height position of the upper wall portion 752a of the holder portion 752. On the other hand, the right auxiliary leg portion 760 is provided at a position slightly above the height position of the lower wall portion 752b of the holder portion 752. The auxiliary leg portion 760 includes a protrusion 760b having a relatively small diameter and a cylindrical shape that protrudes from the tip of the base portion 760a located on the root side. This is because the vicinity of the central portion of the mounting surface 650a of the display control board 650 with which the auxiliary leg portion 760 contacts is a place where various electronic components are densely arranged, so that the contact area with the mounting surface 650a is as much as possible. This is to reduce contact and prevent contact with various electronic components.

  Various reinforcing ribs 762 are provided on the back side of the plate substrate 751 in the vertical and horizontal directions. Thereby, the bending of the plate substrate 751 is suppressed.

  In addition, the plate substrate 751 is provided with a hooking portion 763 for hooking the power supply wiring 702 of the cooling fan 675 at a side position of the holder portion 752.

  A substantially rectangular opening 765 formed in accordance with the outer peripheral shape of the housing 700 of the cooling fan 675 is provided at a substantially central portion of the plate substrate 751 configured as described above. The holder portion 752 is formed so as to protrude from the peripheral edge portion of the opening portion 765 toward the surface side of the plate substrate 751.

  The holder portion 752 has a frame shape formed so that the inner peripheral shape thereof substantially matches the outer peripheral shape of the housing 700 of the cooling fan 675 fitted therein, so that the holder plate 752 can be ventilated in the front and back direction of the mounting plate 670. It penetrates. That is, the holder portion 752 includes four side walls (upper wall portion 752a, lower wall portion 752b, left wall portion 752c, and right wall portion 752d) surrounding the housing 700 of the cooling fan 675.

  Among these, the upper wall portion 752a and the lower wall portion 752b that are opposed to each other with the cooling fan 675 interposed therebetween are provided with locking pieces 768 for preventing the cooling fan 675 from falling off at the substantially central portion in the left-right direction. ing.

  More specifically, in the upper wall portion 752a and the lower wall portion 752b, a pair of cut portions are formed from the root side with the plate substrate 751 toward the projecting side, and the root side of the holder portion 752 between the two cut portions is The locking piece 768 having the root side as a free end is formed so as to be separated from the plate substrate 751. A locking claw 768 a that protrudes toward the inner peripheral side of the holder portion 752 is provided at the distal end portion of the locking piece 768.

  On the other hand, a stopper 770 that protrudes toward the inner peripheral side of the corner is formed at each corner of the protruding opening 752e of the holder 752. Each stopper 770 has a relatively thin and slightly curved shape so as to be elastically deformable.

  Next, a procedure for attaching the cooling fan 675 to the display control board 650 will be described. First, the cooling fan 675 is fitted into the mounting plate 670. More specifically, when a force is applied to the cooling fan 675 in a state where the cooling fan 675 is aligned with the holder portion 752 on the back surface side of the mounting plate 670, the cooling fan 675 elastically holds the locking piece 768. It is pushed into the holder part 752 while being deformed. When the cooling fan 675 is pushed in to some extent, the cooling fan 675 comes into contact with the stopper 770 of the holder portion 752. Here, when the cooling fan 752 is further pushed in while the stopper 770 is elastically deformed, the locking piece 768 returns elastically. Accordingly, the locking claw 768a is locked to the cooling fan 675, and the cooling fan 765 is held in the holder portion 752. In the holder portion 752, the cooling fan 675 is sandwiched between the stopper 770 and the locking claw 768a.

  After completing the mounting of the cooling fan 675, the power supply wiring 702 of the cooling fan 675 is hooked on the hooking portion 763 of the plate substrate 751.

Align to 758. At this time, as described above, since the formation positions of the protrusions 755 in the left-right direction are different between the upper and lower sides, if the attachment plate 670 is to be attached upside down, the protrusions 755 are adjusted accordingly. The position of the recess 758 of the formed display control board 650 does not match and the mounting plate 670 cannot be mounted.

  When a force is applied to the mounting plate 670 in a state where the mounting plate 670 is correctly aligned, the mounting plate 670 is pushed into the display control board 650 side while the locking piece 754 abuts against the recess 757 and elastically deforms.

The

  As described above in detail, in this embodiment, the cooling fan 675 is attached to the display control board 650 in advance via the attachment plate 670 before the display control board 650 is attached to the base plate 645 (substrate box). be able to. As a result, a laborious operation of assembling the cooling fan 675 separately from the display control board 650 on the base plate 645 is not necessary. Furthermore, the power supply wiring 702 of the cooling fan 675 can be connected to the terminal portion 705 of the display control board 650 in advance before the display control board 650 is assembled to the base plate 645. As a result, the assembling workability of the cooling fan 675 is remarkably improved.

  As described above, the mounting of the cooling fan 675 to the mounting plate 670 and the mounting of the mounting plate 670 to the display control board 650 can be performed with one touch without using a fixing tool such as a screw. Efficiency is greatly improved. In addition, the occurrence of problems such as the occurrence of noise due to static electricity charged on screws or the like and malfunction of electronic components can be reduced. Furthermore, an increase in the number of parts can be suppressed.

  Further, since the mounting plate 670 is configured to be locked to the peripheral edge portion of the display control board 650, for example, there is no need to provide a hole, a screw hole, or the like for inserting the locking part into the display control board 650. It is easy to secure a relatively large space for arranging electronic components and wiring patterns. In addition, since the peripheral portion of the display control board 650 is a place where no electronic component or wiring pattern is provided, the operation of locking the locking piece 754 and the locking release operation are relatively easy and workability is improved. Is further improved.

  The engaging claw 754a of the mounting plate 670 is engaged with the recess 757 of the display control board 650, and the engaging claw 754a at the tip is engaged with the back surface 650b of the board. Thereby, the position shift of the mounting plate 670 can be prevented, and the stability of the assembled state can be improved. Moreover, since the recessed part 757 becomes a mark which shows the latching position of the latching piece 754 at the time of the assembly | attachment operation | work of the attachment plate 670, alignment can be performed easily and work efficiency can be improved.

  Further, since the mounting plate 670 is a transparent or translucent member, the mounting plate 670 is disposed even when the mounting plate 670 is disposed so as to cover a relatively wide range of the mounting surface 650a of the display control board 650 as described above. Thus, the mounting surface 650a of the display control board 650 can be visually recognized. As a result, it is possible to minimize the trouble that the visibility of the electronic components such as the CPU 521 is impaired, and even if an illegal act such as replacement of the electronic components such as the program ROM 522 is performed, the illegal act is promptly performed. Can be found. As a result, it also prevents such illegal activities.

  Furthermore, since the mounting plate 670 is non-conductive and the cooling fan 675 is disposed apart from the electronic components of the display control board 650, noise caused by static electricity, vibration, etc. generated in the cooling fan 675 is electronic. Difficult to be transmitted to parts, and malfunctions are unlikely to occur.

  In addition, since the cooling fan 675 is disposed apart from the electronic components of the display control board 650, the electronic components can be confirmed from the side even at a position where the cooling fans 675 face each other. As a result, it is excellent in the early detection of fraud and the deterrent effect. On the other hand, the possibility of overheating of the cooling fan 675 is reduced by not contacting an electronic component that generates high heat such as the VDP 526.

  In general, a board box (unit cover 654) that accommodates a control board has versatility so that it can be used for various electronic components. Therefore, a mounting surface of the control board (mounting surface 650a of the display control board 650) and It is designed to be relatively wide between the wall portion (back wall portion 655) of the substrate box facing this. For this reason, there is a lot of extra space in the board box, and it is difficult to efficiently cool the electronic components mounted on the control board simply by convection of air by the blower (cooling fan 675). In contrast, if the outside air is blown toward the control board, the predetermined electronic component can be efficiently cooled. However, even in such a configuration, the range of efficient cooling is not so wide and limited.

  In this regard, if the cooling fan 675 is attached to the display control board 650 via the attachment plate 670 as in this embodiment, the attachment plate 670 (plate board 751) is the back wall portion 655 of the unit cover 654. Rather than the mounting surface 650a of the display control board 650. That is, the flow path of the air blown from the cooling fan 675 is narrowed. For this reason, more electronic components can be efficiently cooled in a wider range. Thus, particularly when the mounting plate 670 (plate substrate 751) is arranged closer to the mounting surface 650a of the display control substrate 650, the above-described effect of the mounting plate 670 being a transparent or translucent member is more effective. It will be effective.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the example in which the mounting structure of the cooling fan 675 is applied to the display control device 45 has been shown. However, the present invention is applied to the mounting structure for other control devices such as the main control device 261. Also good.

  (B) The material of the mounting plate 670 is not limited to the above embodiment. For example, you may comprise with an opaque member and may comprise with an electroconductive member. When constituted by a conductive member, it may be used as a ground.

  (C) The shape and structure of the mounting plate 670 are not limited to the above embodiment. For example, the protrusion 755, the support leg 753, the auxiliary leg 760, the reinforcing rib 762, the hook 763, and the like may be omitted. When both the support leg 753 and the auxiliary leg 760 are omitted, the cooling fan 675 directly contacts the mounting surface 650a of the display control board 650 or a predetermined electronic component via a heat sink or the like. In this state, the locking piece 754 of the mounting plate 670 is locked to the display control board 650.

  In addition, the holder portion 752, the auxiliary leg portion 760, the latching portion 763, and the like may be configured to be relatively movable with respect to the plate substrate 751 so that the position thereof can be adjusted.

  In addition, the cooling fan 675 can be attached to the holder portion 752 from the surface side of the attachment plate 670, and after the attachment plate 670 is attached to the display control board 650, the cooling fan 675 is attached to the attachment plate 670. It is good.

  (D) In the above embodiment, the mounting plate 670 is configured to be locked to the upper edge portion 650c and the lower edge portion 650d of the display control board 650. However, the present invention is not limited to this, and the mounting plate 670 is, for example, It is good also as a structure latched by the right-and-left edge part of the display control board 650. FIG.

  (E) In the above-described embodiment, the cooling fan 675 is disposed opposite to a predetermined area between the CPU 521 and the VDP 526. However, the present invention is not limited to this. For example, the cooling fan 675 is opposed to a specific electronic component such as the CPU 521 or the VDP 526. It is good also as a structure arrange | positioned. In this way, it is possible to intensively blow outside air cooler than the air in the board box to specific electronic components such as the VDP 526 and the like that emit high heat, and efficiently cool the electronic components.

  Moreover, it is good also as a structure which is equipped with the heat sink (heat sink) for dissipating the heat | fever of the electronic component which generate | occur | produces heat, and the cooling fan 675 is arrange | positioned so that the said heat sink may be cooled.

  Further, as in the above-described embodiment, the blowing direction of the cooling fan 675 is not directed in a direction substantially orthogonal to the mounting surface 650a of the display control board 650, but is directed in a direction substantially parallel to the mounting surface 650a of the display control board 650. Alternatively, a configuration in which the cooling fan 675 is disposed may be employed. That is, the mounting plate 670 to which the cooling fan 675 can be assembled in such a direction may be employed. Of course, even when the air blowing direction of the cooling fan 675 is directed in a direction substantially orthogonal to the mounting surface 650a of the display control board 650, the cooling fan 675 is used for exhausting air in a direction away from the mounting surface 650a. It is good also as a structure which functions.

  (F) You may implement as a different type of pachinko machine from the said embodiment. In addition to pachinko machines, the game is implemented as an arrangement ball machine, various types of game machines such as sparrow balls, slotted machines such as slot machines, and a game machine that combines slot machines and pachinko machines. Also good.

  Hereinafter, the technical idea that is not described in the claims and that can be grasped from the above embodiment will be described together with the effects thereof.

Means 1. A gaming machine that performs a lottery based on a predetermined opportunity and generates a special gaming state advantageous to a player when a winning result is obtained by the lottery,
A control board on which various electronic components are mounted, and a board box that houses the control board,
A predetermined blower;
A gaming machine configured to be capable of holding the blower and having a mounting member for mounting the blower on the control board.

  According to the above means 1, the blower can be assembled to the control board in advance through the mounting member before the control board is assembled to the board box. For example, the blower is first held on the mounting member. Then, the mounting member is mounted on the control board. Thereafter, the control board is assembled to the board box. For this reason, it is not necessary to perform the troublesome work of assembling the blower separately from the control board with respect to the board box. Furthermore, before the control board is assembled to the board box, the power supply wiring of the blower can be connected to the control board in advance. As a result, the assembling workability of the blower can be remarkably improved, and as a result, the working efficiency at the time of assembling the substrate box can be remarkably enhanced.

  In addition, if the mounting member is configured to “attach the blower to the control board in a state where the blower is opposed to the surface (mounting surface) of the control board (the blowing direction is substantially orthogonal to the mounting surface)” Air can be efficiently blown to the electronic components mounted on the control board.

  Mean 2. The gaming machine according to means 1, wherein the mounting member is constituted by a transparent member or a translucent member.

  In addition to the blower, the mounting member is disposed on the substrate surface side, so that a wider area of the substrate surface is covered, and the visibility of the substrate surface may be reduced.

  On the other hand, according to the above means 2, even when the mounting member is arranged so as to overlap the substrate surface, the substrate surface can be visually recognized through the mounting member made of a transparent member or the like, and the electronic components such as the CPU are visually recognized. It is possible to minimize problems such as loss of performance.

  In other words, the electronic component can be easily confirmed without removing the mounting member. For this reason, even if a fraudulent act such as replacement of an electronic component such as a ROM is performed, the fraudulent act can be detected at an early stage, and such a fraudulent act can be suppressed. In general, in gaming machines such as pachinko machines, the board box itself is also made of a transparent member or the like from the viewpoint of preventing fraud. Therefore, even when the board box is attached to the gaming machine body, the electronic components can be easily confirmed from the outside of the board box.

  In addition, as a method for assembling the blower, for example, a method of fixing the blower to a heat radiating plate (heat sink) for dissipating heat of the electronic component that generates heat is conceivable. However, since the heat radiating plate is usually made of metal and lacks visibility, the visibility of the electronic component may be lowered for the same reason as described above. For this reason, from the viewpoint of preventing fraud, in a gaming machine such as a pachinko machine, it is preferable to omit a heat sink that reduces visibility. If the heat sink is omitted, of course, the method of assembling the blower using the heat sink cannot be adopted.

  Means 3. The gaming machine according to claim 1 or 2, wherein the mounting member includes a locking portion that is locked to the rear side of the peripheral edge of the control board.

  Here, the peripheral edge of the control board refers to a portion where no electronic components or wiring patterns are provided around the control board. That is, it includes not only the end surface around the control substrate but also a range having a certain width from the end surface inward to the substrate.

  As a method of assembling the mounting member to the control board, a method of fixing with a fixing tool such as a screw is considered as the most general method, but there are problems as exemplified below.

  For example, when screwing, the mounting member and the screw hole provided in the control board must be matched, and fixing work must be performed using a tool such as a screwdriver, which may significantly reduce the work efficiency. There is. In addition, since a large number of screws and the like are required, problems such as an increase in the number of parts and an increase in man-hours are caused.

  In addition, screw holes and the like must be provided in the control board, and an area where electronic parts and wiring patterns cannot be arranged increases.

  Furthermore, noise is generated due to static electricity charged on a screw or the like, which may lead to malfunction of an electronic component. In particular, when such a problem occurs on a display control board in a gaming machine, the effect appears as a problem such as flickering on the display screen, so the effect directly on the player is great.

  In this respect, according to the means 3, since it can be easily attached and detached without using a fixing tool such as a screw, the working efficiency is remarkably improved. In addition, an increase in the number of parts can be suppressed.

  Further, since the mounting member is locked to the peripheral edge of the control board, it is not necessary to provide a hole or screw hole for inserting the locking part into the control board, and to arrange electronic components and wiring patterns. It is easy to secure a relatively large space. Further, since the peripheral portion of the control board is a place where no electronic component or wiring pattern is disposed, the operation of locking the locking portion and the unlocking operation are relatively easy, and workability is improved.

Thereby, position shift prevention of a mounting member can be aimed at and stability of an assembly state can be improved. In addition, since the concave portion serves as a mark indicating the locking position of the locking portion during the assembly work of the mounting member, it is easy to perform alignment and work efficiency can be improved.

  Means 5. The gaming machine according to claim 3 or 4, further comprising a support portion that abuts on the front side of the peripheral portion of the control board and supports the blower device in a state of being separated from the electronic components of the control board.

  According to the means 5, the locking portion and the support portion of the mounting member function as a clamping means for clamping the peripheral edge portion of the control board, and the stability of the assembled state of the blower can be improved.

  In addition, the heat sink mentioned above is attached so that it may closely_contact | adhere to the electronic component which heat | fever-generates on the function. Therefore, in the configuration in which the blower is assembled via the heat sink, noise caused by static electricity or vibration generated in the blower is transmitted to the electronic component via the heat sink, and a malfunction may occur. On the other hand, in the said means 5, since an air blower is arrange | positioned in the position away from the electronic component of the control board, such a malfunction can be suppressed.

  Moreover, since the air blower floats from the substrate surface, the electronic component can be confirmed from the side even at a position where the air blower faces each other. As a result, it is excellent in terms of early detection of fraud and deterring effects.

  Means 6. The gaming machine according to any one of means 1 to 5, wherein the mounting member is made of a non-conductive material.

  If a conductive metal mounting member is used, noise caused by static electricity or vibration generated in the blower is transmitted to the wiring pattern of the control board via the mounting member, and thus to the electronic component. There is a risk of malfunction. On the other hand, in this means 6, since the mounting member is made of a non-conductive material (for example, a non-conductive synthetic resin material), such a problem can be suppressed.

  According to the said means 10, the rigidity of a mounting member can be improved and stability of the assembly | attachment state of an air blower can be improved.

  For example, when the mounting member is mounted so as to be bridged between opposite sides of the peripheral edge of the control board, the vicinity of the central part of the mounting member is in a state of floating from the substrate surface. There is a risk that it will be easily bent. On the other hand, by providing the reinforcing rib as described above, such a problem can be suppressed, and even when the blower is disposed near the center, the assembled state of the blower is stable. Improves.

  Further, instead of or in addition to this, in addition to the support portion that contacts the peripheral portion of the control board, an auxiliary support portion that contacts the control board may be provided.
