Description

  The present invention relates to a gaming machine such as a pachinko machine.

  2. Description of the Related Art Conventionally, on the back side of gaming machines such as pachinko machines, various control devices for performing various controls related to games, payout mechanisms for paying out game balls, and the like are arranged vertically and horizontally. Examples of the control device include a main control device that performs overall control of the game, a payout control device that controls the payout device for game balls, a display control device that controls the display device for performing display effects, a speaker, a lamp, and the like. An audio lamp control device or the like for control is provided.

  In recent years, as electronic components such as a central processing unit (CPU) constituting a main control unit of a control device become more sophisticated and the amount of control data increases, various electronic components mounted on a control board tend to increase. Therefore, the size of the control board and thus the resin case (board box) for housing the control board tends to increase. For example, a liquid crystal display device or the like is adopted as the display device, and the liquid crystal display unit tends to be gradually enlarged in order to improve interest. The size is also increasing in proportion to the liquid crystal display. Therefore, the occupied area occupied by the display device (display control device) on the back side of the gaming machine is also increasing, and other control devices must be installed so as to avoid the installation space of the display device. The current situation is getting harder.

  In addition, since electronic components such as a CPU mounted on a control board are accompanied by heat generation, conventionally, in a control device, for example, a heat dissipation hole is provided in a board box that accommodates the control board to efficiently release heat generated from the electronic parts. Various heat dissipation measures are taken for this purpose.

  As described above, 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. If a large amount of heat is generated in the resin case in this way, the heat dissipation hole alone cannot sufficiently release the heat, and the control device may malfunction due to the heat generated by the electronic component. . Therefore, in recent control devices equipped with high-performance electronic components, more efficient heat dissipation measures such as mounting a cooling fan are required.

  In particular, electronic components that generate high heat, such as a CPU, may cause a so-called thermal runaway if overheated to a predetermined temperature or higher, and may include a heat sink (heat sink). Therefore, in order to further increase the cooling efficiency, it is conceivable to increase the size of the heat sink. However, as in the case of the above-described control device that must be disposed in a limited installation space such as the back side of the gaming machine, It is not preferable to provide a large heat sink where space is required.

For this reason, in order to efficiently cool electronic components that generate high heat, such as a CPU, without increasing the size of the heat sink, some of the control devices are relative to a specific electronic component such as a CPU mounted on the control board. In some cases, a cooling fan is attached to the back side of the substrate box (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-314423

  As described above, since the installation space on the back side of the gaming machine is limited, it has been reaching the limit to increase the size of the control board or newly add a control device as it is conventionally. Therefore, in recent years, it has been attempted to arrange the control devices so as to overlap each other.

  However, when the control devices are arranged one behind the other, if the cooling fan is provided on the back side of one control device as described above, the other control placed on the back side of the control device is provided. Since the ventilation hole (ventilation space) for the cooling fan is blocked by the device, the cooling fan may not function sufficiently.

  If both control devices are not brought into close contact with each other and a sufficient clearance (ventilation space) is required between them to allow the cooling fan to function, a considerably large clearance is required. The side mechanism may expand in the depth direction and become large.

  In addition, the said subject is a problem applicable not only to a pachinko machine but other game machines, such as a slot machine.

Thereby, while ensuring the structure which can mount the audio | voice lamp control apparatus 560 on the back side of the display control apparatus 45, air permeability with the cooling fan 675 and the exterior is enough, without being disturbed by the said audio | voice lamp control apparatus 560. Secured. As a result, it is easy to secure a larger space for installing the sound lamp control device 560 without impairing the heat dissipation performance of the display control device 45.

  Further, in the present embodiment, the cylindrical portion 688 constituting the ventilation means is formed so as to pass straight through the insertion hole 689 of the sound lamp control board 561 in the front and rear of the board box 562. For this reason, the cylindrical portion 688 can be formed at a relatively short distance without having a complicated shape that bypasses the sound lamp control board 561, and the ventilation performance can be improved.

  Furthermore, since the cylindrical portion 688 is not in communication with the inside of the board box 562, the influence on the electronic component mounted on the sound lamp control board 561 can be reduced.

  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 present invention is applied to the relationship between the display control device 45 and the sound lamp control device 560 has been shown, but the present invention may be applied to other control devices such as the main control device 261. Good.

  (B) In the above embodiment, the ventilation means is constituted by the cylindrical portion 688 or the like that is formed through and through the board box 562 straight through the insertion hole 689 of the sound lamp control board 561. However, the present invention is not limited to this, and the shape and structure of the control device and the ventilation means can be changed as needed.

  For example, as shown in FIG. 13, one of the cylindrical portions 688 may be open on the back surface of the box base 563 and the other may be open on the side wall portion of the box cover 564. More specifically, a rectangular insertion hole 687 is formed in the box base 563 corresponding to the fan duct portion 663 of the unit cover 654, as in the above embodiment. The box cover 564 is formed with a cylindrical portion 688 having a quadrangular cross section that is connected to the insertion hole 687. However, the cylindrical portion 688 in this embodiment includes a first cylindrical component portion 688a extending straight from the insertion hole 687 toward the back surface of the sound lamp control board 561, and a predetermined cover cover 564 extending from the first cylindrical component portion 688a. The second tube constituting portion 688b extends straight along the back surface of the sound lamp control board 561 toward the side wall portion 564b. That is, the cylinder part 688 in this embodiment is not formed straight from the box base 563 toward the back wall part 564a of the box cover 564 opposite to the box base 563. As a result, one bent side of the substrate box 562 is opened on the back surface of the box base 563 and the other is bent on the side wall portion 564b of the box cover 564 perpendicular to the box base 563. As in the above-described embodiment, air permeability between the cooling fan 675 and the outside is ensured. Thereby, in the sound lamp control board 561, it is not necessary to form a through-hole portion such as the insertion hole 689 for allowing the tube portion 688 to pass therethrough, and the size of the sound lamp control board 561 can be increased.

  Further, for example, when the cooling fan 675 is disposed in the vicinity of the peripheral edge of the display control board 650, the ventilation means is not formed in the ventilation cylinder but formed in the box cover 564 as shown in FIGS. The substantially U-shaped notch 694 and the substantially L-shaped notch 695 may be used.

  (C) In the above embodiment, the cooling fan 675 is arranged opposite to the CPU 521 and blows air toward the CPU 521. Not limited to this, the cooling fan 675 may be disposed so as to face at least the mounting surface of the display control board 650. Therefore, as long as it is arranged in this manner, it may be arranged opposite to other electronic components such as VDP 526, or the cooling fan 675 is replaced with an exhaust fan, and the air in the display control device 45 is changed. It is good also as a structure discharged | emitted from the said cylinder part 688 grade | etc.,. The fan duct portion 663 and the like may be omitted, and the cooling fan 675 may be attached to the unit cover 654.

  (D) In the above embodiment, only one cooling fan 675 and one cylindrical portion 688 as a ventilation means are provided, but a configuration in which a plurality of them are provided may be employed.

  (E) In the above embodiment, the cylindrical portion 688 and the like as the ventilation means are integrally formed with the box cover 564. However, the present invention is not limited to this, and a separately molded one is assembled to the box cover 564. Also good.

  (F) In the above embodiment, the sound lamp control device 560 is placed so as to be in direct contact with the back wall portion 655 of the unit cover 654 (display control device 45). It is good also as a structure mounted via.

  (G) Although the heat sink 670 is provided in the above embodiment, a configuration in which this is omitted may be employed.

  (H) A configuration in which another control device (board box) is attached to the back side of the sound lamp control device 560, and ventilation means connected to the cooling fan 675, the cylindrical portion 688, and the like is formed in the control device. Also good.
