Description

  The present invention relates to a board case that is provided on the rear surface of a gaming machine and accommodates and holds control boards for various electric components.

  For example, in pachinko machines and arrange ball machines, which are one of the representative examples of gaming machines, game nails, windmills, etc. that change the flow direction of pachinko balls are provided on the game board set in the machine, while symbol display devices and Various electric parts such as an electric prize-winning device, a speaker, and other lighting devices are arranged. Then, by connecting each of the electrical components to a control device and operating the corresponding electrical component based on the control of the control device, a required pachinko game is developed and sound effects are adapted to the pachinko game. And decorative light is revealed. Here, the control device is configured such that a control board on which various control components (microprocessors) are mounted is housed in a protective board case, and the control board cannot be directly touched from the outside.

By the way, with the adoption of large-sized liquid crystal devices, which have become mainstream in recent years, and the enlargement / movability of electrical decoration devices, more sophisticated and complicated electrical control processing is required for the control board. Accordingly, the amount of electric power used in the control board during the game increases, and the amount of heat generated from the control board tends to increase year by year. Therefore, in order to prevent heat generated in the control board from staying in the board case and causing problems in the control board, there are many gaming machines provided with a cooling fan in the board case. In the board case having such a cooling fan, a ventilation hole is provided in a portion facing the cooling fan, and the control board is cooled by taking external air into the case through the ventilation hole (for example, , See Patent Document 1).

  By the way, while the adoption of the above-described gaming machine with large power consumption is progressing, a gaming machine that employs a display device other than a liquid crystal device as the symbol display device, such as a gaming machine that has been used in the past, or a simple Demand for gaming machines equipped with lighting devices remains as before. The control board provided in such a gaming machine does not require the above-described advanced control processing capability, and the amount of heat generated from the control board is relatively small. In addition, control boards with reduced heat generation have appeared due to improvements in the processing capacity of the control boards as a result of technological development. Therefore, such a control board with little heat generation can operate normally enough by natural heat radiation without resorting to forced cooling by the cooling fan. Therefore, when the control board generates little heat and the cooling fan is not necessary, the ventilation hole for the cooling fan described above does not need to be provided in the board case. For such a gaming machine, the ventilation hole is not provided. At present, a substrate case of a type that does not have is separately manufactured and used.

  However, if different board cases are used according to the type of gaming machine, that is, whether or not a cooling fan is required, the manufacturing cost will rise, so a proposal for a board case that can be used in any gaming machine is required. It has been. Although it is possible to use a board case having a vent hole for a gaming machine that does not require a cooling fan, in this case, the vent hole is always open without being blocked by the cooling fan. End up. Therefore, there is a possibility that a go-to action for inserting a wire-like illegal instrument or the like into the substrate case through the ventilation hole is allowed. That is, there is a problem in crime prevention when the substrate case having the ventilation holes is applied to a gaming machine that does not require a cooling fan as it is.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a substrate case that can be used regardless of whether a cooling fan is necessary and can also prevent a go-to action.

However, the substrate case according to the present invention is not limited to a pachinko machine, and can also be used in an arrangement ball machine, a slot machine, a slot machine using a pachinko ball (so-called parrot machine), and the like. That is, it is possible to adopt the board case according to the present invention in place of the conventional board case that accommodates the control board of the electrical component in various gaming machines. Further, the substrate case shown in the embodiment is described as accommodating a display control board for controlling a liquid crystal display device (LCD), but the substrate case according to the present invention is limited to the one accommodating a display control board. It does not mean that it can accommodate a control board that controls various electrical components. In the following description, “left” and “right” are designated when the game board of the pachinko machine is viewed from the rear side as shown in FIG. 1 unless otherwise specified.

  As shown in FIG. 1, an opening (not shown) through which a display screen 14a of a liquid crystal display device 14 (see FIG. 2) faces is formed in the game board 12 of the pachinko machine on which the board case 10 according to the embodiment is mounted. In addition to being established, an attachment member 16 is disposed on the rear surface of the game board 12 along the opening. The board case 10 is attached to the rear surface 12 a of the game board 12 via an attachment member 16. The substrate case 10 is a rectangular box-like case body that is long in the width direction, and an accommodating portion 18 is defined therein.

The member 16 is detachably attached. That is, the substrate case 10 constitutes a symbol display unit together with the liquid crystal display device 14 and the display control substrate 20, and can be handled in units. In addition, the left rear surface (second back surface portion 42 described later) of the substrate case 10 accommodates a second control board (not shown) that controls and controls a plurality of control boards including the display control board 20. The case 22 is detachably attached.

  As shown in FIG. 2A, the substrate case 10 according to the embodiment has a lower side formed in a stepped section and an open portion 24 opened on the front surface, and the liquid crystal display device 14 in the housing portion 18 The display screen 14a is housed in a state where it faces the opening 24. The display control board 20 is attached to the rear side of the liquid crystal display device 14 via a support base 26 provided in the accommodating portion 18. The display control board 20 is disposed so that a required space S is defined between the display control board 20 and the back surface portion 28 facing rearmost in the board case 10, and the display control board 20 is cooled in the space S. A cooling fan (not shown) can be provided. That is, as shown in FIG. 2 and FIG. 3A, a box-shaped mounting portion 30 opened forward is provided on the housing portion 18 side of the back surface portion 28 of the substrate case 10 so that the cooling fan If necessary, a cooling fan can be installed in the mounting portion 30.

  As shown in FIG. 3 (a), a plurality of heat radiation holes 32 are provided in the upper and lower portions of the back surface portion 28 of the substrate case 10 for releasing the heat in the accommodating portion 18 to the outside, and the cooling fan takes in external air. A plurality of ventilation holes 34 are provided so as to form a circular shape. Furthermore, a pair of fitting holes (fitting parts) 40 and 40 into which positioning pieces 38 of a shielding member 36 described later are fitted are formed on the back surface part 28 at a circular center part formed by the ventilation holes 34. It is provided outside the circular shape with a sandwich. In addition, the said heat radiating hole 32 is set as a small opening dimension compared with the ventilation hole 34, and it is difficult to insert an unauthorized instrument etc. from this heat radiating hole 32. FIG. Further, as shown in FIG. 2, a plurality of the heat radiating holes 32 are also provided on the upper surface and the lower surface of the substrate case 10. Furthermore, a second back surface portion 42 is formed on the rear surface of the substrate case 10 and one step ahead of the back surface portion 28, and a plurality of heat radiation holes 32 are formed in the upper and lower portions of the second back surface portion 42. (See FIG. 3).

As shown in FIGS. 3B and 4, the shielding member 36 that is selectively mounted on the back surface portion 28 of the substrate case 10 is set to a size that allows the ventilation hole 34 and the fitting hole 40 to be closed. A pair of engaging pieces 44 and 44 and positioning pieces 38 and 38 are integrally formed on a surface (one surface) 36a that is in contact with the substrate case 10 (front side) 36a. ing. That is, a pair of the engaging pieces 44 and 44 are arranged on one diagonal line (one straight line passing through the center of the shielding member 36) l _{1 of the} shielding member 36 with the center O interposed therebetween, and the diagonal line l ₁ and orthogonal to the other diagonal line (the other line) on l _2, the positioning pieces 38, 38 of the pair are disposed across the center O. The engagement piece 44 is inserted into one ventilation hole 34 corresponding to the case where the shielding member 36 is attached to the substrate case 10, and is engaged with the outer peripheral edge 34a of the ventilation hole 34 on the inner surface of the case as shown in FIG. Configured to do.

  The positioning piece 38 is adapted to be fitted into the fitting hole 40 from the outside when the shielding member 36 is attached to the substrate case 10. As shown in FIG. 5, each positioning piece 38 is set to a size that substantially matches the opening size of the fitting hole 40, and the positioning piece 38 is attached to the board case 10 by fitting into the fitting hole 40. The movement in the direction along the surface of the shielding member 36 can be restricted. Thereby, the movement to the direction (refer arrow of FIG. 5) which cancels | releases the engagement state of the engagement piece 44 with respect to the shielding member 36 is controlled. Moreover, the engaging pieces 44 and 44 and the positioning pieces 38 and 38 are formed on the surface 36 a of the shielding member 36 that contacts the substrate case 10. Accordingly, when the shielding member 36 is attached to the substrate case 10, it is impossible to access the engaging pieces 44 and 44 and the positioning pieces 38 and 38 from the outside, and the shielding member 36 is removed from the outside of the substrate case 10. I can't do that. As the material of the shielding member 36, for example, a polycarbonate (PC) resin having excellent deformation resistance and impact resistance is preferably used.

(Operation of Example)
Next, the operation of the substrate case 10 according to the embodiment will be described. First, the case where the amount of heat generated by the display control board 20 is small and there is no need to install a cooling fan will be described. When it is not necessary to install a cooling fan in the substrate case 10, as shown in FIG. 3A, the ventilation hole 34 is opened without being shielded by the cooling fan. Further, since the pair of fitting holes 40, 40 provided around the ventilation hole 34 is also opened, an unauthorized device or the like is placed in the substrate case 10 through the ventilation hole 34 and the fitting hole 40. There is a risk of being inserted into. Therefore, when a cooling fan is not required, it is possible to shield the ventilation hole 34 and the fitting hole 40 that may be used for fraud by attaching the shielding member 36 to the substrate case 10. Become.

  That is, when the shielding member 36 is attached to the substrate case 10, as shown in FIG. 6A, first, one engagement piece 44 is first inserted into the corresponding ventilation hole 34, and the engagement piece 44 is ventilated. 34. Then, as shown in FIG. 6 (b), the shielding member 36 is pushed so that the other engagement piece 44 is inserted into the corresponding ventilation hole 34, and the engagement pieces 44, 44 are inserted into the ventilation holes in the substrate case 10. The outer peripheral edge portions 34a, 34a of 34, 34 are engaged with each other. At this time, as shown in FIG. 5, the positioning pieces 38, 38 are fitted into the fitting holes 40, 40 to restrict the movement of the shielding member 36. That is, since the positioning pieces 38 and 38 restrict the movement of the engaging pieces 44 and 44 in the releasing direction with respect to the shielding member 36, it is impossible to remove the shielding member 36 from the outside of the substrate case 10.

  Next, when the display control board 20 generates a large amount of heat and it is necessary to install a cooling fan, the board case 10 is installed on the game board 12 after the cooling fan is installed on the mounting part 30. Further, it is not necessary to attach the shielding member 36 to the substrate case 10, and the ventilation hole 34 is opened. As a result, the cooling fan can take external air into the substrate case 10 through the ventilation holes 34, and the display control substrate 20 can be suitably cooled. Here, even if an unauthorized device is inserted through the ventilation hole 34 and the fitting hole 40, since it is interfered by the cooling fan, it is possible to prevent an illegal act.

  As described above, according to the substrate case 10 according to the embodiment, the ventilation hole 34 for the cooling fan is closed by the shielding member 36, so that the goto action can be suitably prevented. Therefore, the board case 10 can be used even in a gaming machine that does not require a cooling fan. Moreover, what is necessary is just to install the board | substrate case 10 without using the said shielding member 36 with respect to the game machine provided with a cooling fan. That is, by selectively mounting the shielding member 36 according to the necessity of the cooling fan, the common substrate case 10 can be used regardless of the necessity of the cooling fan, and the manufacturing cost can be reduced. it can. Further, the engaging piece 44 engages with the inner surface of the substrate case 10 and the positioning piece 38 faces the fitting hole 40 and restricts the movement of the shielding member 36 in the surface direction. It becomes impossible to remove from the outside of 10, and it is possible to realize the sure prevention of the goto action.

Further, since the pair of engaging pieces 44 and 44 are provided on one diagonal line l ₁ of the shielding member 36 and the pair of positioning pieces 38 and 38 are provided on the other diagonal line l ₂ , the surface direction of the shielding member 36 is determined. And the removal from the outside of the substrate case 10 can be more reliably disabled. Further, by using the ventilation holes 34 as the through holes with which the engagement pieces 44 are engaged, it is not necessary to separately provide the through holes in the substrate case 10 and the configuration of the substrate case 10 can be simplified.

  Although the board case 10 shown in the embodiment is attached to the rear surface 12a of the game board 12, it may be attached to other members such as the main body of the gaming machine. In addition, the substrate case 10 of the embodiment is formed in a box shape that forms a closed space. However, for example, the substrate case 10 may have a shape with open side surfaces and upper and lower surfaces.

  The shielding member 36 in the embodiment has a configuration in which the engagement piece 44 is engaged with one of the plurality of ventilation holes 34 arranged in a circular shape. However, it is not always necessary to provide a plurality of ventilation holes 34. For example, a single circular or rectangular ventilation hole 34 may be provided, and the engagement piece 44 may be engaged with the inner peripheral edge thereof. In the embodiment, the engagement piece 44 is engaged with the ventilation hole 34, but a through hole with which the engagement piece 44 engages may be provided in the substrate case 10 separately. Further, three or more engaging pieces 44 may be provided, or the positioning pieces 38 and 38 may be omitted to make all the engaging pieces 44.

  In the embodiment, the shape of the shielding member 36 is rectangular, but may be other shapes such as a circle or an ellipse as long as the ventilation hole 34 can be covered. Further, although the fitting hole 40 into which the positioning piece 38 is fitted is configured as a “through hole” that penetrates the board case 10, a concave fitting portion that the positioning piece 38 faces may be provided in the board case 10.
