Description

  The present invention relates to a gaming machine, and relates to a technique for cooling a display, an inverter board, and the like.

The gaming machine is provided with a display for displaying contents related to the game (for example, a change display of symbols, etc.), an inverter board for relaying signals to the display and supplying electric power. Since these indicators, inverter boards, and the like generate heat when energized, there is a possibility that the game cannot be normally performed due to thermal runaway or failure unless it is cooled. Thus, conventionally, an example of a technique for cooling the inside of the housing of the display with a cooling fan has been disclosed (see, for example, Patent Documents 1 and 2).
Japanese Patent Laid-Open No. 2002-45530 (page 6-7, FIG. 4) JP-A-9-308735 (6th page, 9th page, FIGS. 4 and 11)

However, in the technique described in Patent Document 1, since the cooling fan is disposed near the side surface on one side of the display as a heat source, it is difficult to eliminate the heat accumulated near the side surface on the other side. Therefore, the entire display cannot be cooled almost uniformly.
Further, in the technique described in Patent Document 2, since the display, the inverter board, and the cooling fan are arranged corresponding to each side of the triangle when viewed from the side (see FIG. 11 of Patent Document 2), the triangle No device can be placed in the center of the space, and space cannot be used effectively. In recent years, the number of devices, members, and the like that must be attached to the periphery of the display has increased, and there is a demand for a configuration in which the display, the inverter board, and the like can be arranged in a compact manner.
The present invention has been made in view of these points, and it is possible to arrange the display unit, the inverter board, etc. in a compact manner by effectively utilizing the space, and to cool the display unit, the inverter board, etc. substantially uniformly. An object is to provide a gaming machine configured as described above.

(1) Means for solving the problem (hereinafter, simply referred to as “solution means”) 1 includes a display for displaying contents relating to a game, and a back side of the display (opposite of the display surface of the display). A game machine having a cover member provided in the space formed by the cover member and an inverter board disposed in a space formed by the cover member, The gist of the invention is that the cover member is provided with a through-hole through which air flows, and a cooling device for flowing air through the through-hole at the time of cooling is provided on the back side and substantially in the center of the cover member.

  According to the solution 1, the display device, the inverter board, the cover member, and the cooling device are arranged in this order. The space formed by the cover member ensures the flow of air generated during cooling. Since it is sufficient if the flow of air can be ensured, it is sufficient if a minimum space is secured without requiring a large space. The cover member has a function of guiding air to the cooling device through the through hole, and preferably has a structure that functions to protect the display and the inverter board. According to the arrangement described above, the display device, the inverter board, and the like can be arranged in a compact manner. Therefore, since the cooling device is not disposed on the side surface side of the display and the cover member as in the conventional case, other devices (for example, an accessory, etc.) and members (for example, a ball passage) can be disposed. Further, since the cooling device for cooling through the cover member is disposed on the back side of the inverter board and substantially at the center, the entire display unit, inverter board, and the like can be cooled substantially uniformly.

(2) The solution means 2 is the gaming machine described in the solution means 1, and the inverter board has a signal relay function for relaying a signal to the display.

  The inverter board has a power supply function for converting DC power into AC power and supplying power corresponding to the operation of the display. The inverter board in the solution 2 has not only a power supply function but also a signal relay function. Therefore, it is not necessary to provide a signal relay board separately, and the power supply function and the signal relay function are achieved only by providing the inverter board on the back side of the display. Therefore, it is not necessary to perform an operation of installing a signal relay board, and the assembly work time can be shortened.

(3) The solution means 3 is the gaming machine described in the solution means 1 or 2, and the gist is that the cover member is provided with a number of through holes.

  According to the solution 3, since the cover member is provided with a large number of through holes, even when the cooling device is operated to the maximum, air can be reliably flowed during cooling, and the cooling efficiency is increased.

(4) The solving means 4 is the gaming machine described in any one of the solving means 1 to 3, and the gist is that the cooling device is configured to suck out the air inside the cover member.

  When the cooling device is operated so that air flows toward the inverter board, the inverter board can be cooled, but the inverter board is provided on the back side of the display, so the inverter board becomes an obstacle. The display cannot be cooled efficiently. Moreover, the heat generated in the display and the inverter board is likely to be trapped inside the cover member. According to the solution 4, since the air inside the cover member (that is, heated air) is guided to the cooling device so as to be sucked out, both the display unit and the inverter board can be cooled as a result. . For example, a cooling fan is used as the cooling device.

(5) The solving means 5 is the gaming machine according to any one of the solving means 1 to 4, wherein the cover member has a distance adjusting mechanism for adjusting a distance from the inverter board. To do.

  According to the solution 5, the air flowing through the predetermined space becomes gentle if the distance to the inverter board is increased, and the air flowing through the predetermined space becomes faster if the distance is reduced. That is, if the air flows gently, the heat that escapes per unit time decreases and the cooling rate decreases, and if the air flows quickly, the heat that escapes per unit time increases and the cooling rate increases. When a gaming machine is installed at a position where heat is difficult to escape, the distance from the inverter board is narrowed to increase the cooling rate, and when a gaming machine is installed at a position where heat is easy to escape, even if the cooling rate is low Increase the distance because it is good. Thus, even without controlling the operation of the cooling device, the display, the inverter board, and the like can be reliably cooled only by adjusting the distance from the inverter board by the distance adjusting mechanism.

  According to the present invention, the cooling device arranged on the back side of the cover member is cooled so that the air inside the cover member is sucked out, so that the display, the inverter board, etc. can be arranged compactly by effectively utilizing the space. The display, the inverter board and the like can be cooled almost uniformly. As a result of the arrangement, other devices and members can be arranged on the side surfaces of the display and the cover member.

  Next, the best mode for carrying out the present invention will be described with reference to examples.

  This embodiment is an example in which the present invention is applied to a pachinko machine that is one of gaming machines, and will be described with reference to FIGS.

[Appearance of pachinko machine]
First, the external appearance of the card unit 10 and the pachinko machine 12 is shown in FIG. The card unit 10 can input and output balance information and valuable value information recorded on a recording medium (for example, a magnetic card or an IC card), and corresponds to an amount desired by the player within the range of the balance information. A number of pachinko balls that can be lent are configured to be lent out. The specific configuration, operation, and the like of the card unit 10 are the same as well-known configurations, so illustration and description are omitted.
On the front side of the pachinko machine 12, a game board 14 for playing with a pachinko ball as a game medium is provided, and the game board 14 is provided with a liquid crystal display 16 for displaying information on the pachinko game. The liquid crystal display 16 corresponds to a display and can be applied instead of an EL display, a plasma display, a CRT, or the like. Although not shown, the game board 14 is appropriately provided with a winning opening (including a large winning opening and a starting opening), a gate, a windmill, and an obstacle nail.

[Configuration example of liquid crystal display, inverter board, cooling fan, etc.]
Next, an example in which an inverter board, a cooling fan, and the like are assembled to the liquid crystal display 16 will be described with reference to FIGS. FIG. 2 shows an exploded perspective view of the configuration example, and FIG. 3 shows an example in which an inverter board is mounted on the back side of the liquid crystal display 16.
In the following description, when simply referred to as “front side” and “back side”, the side facing the display surface 16a of the liquid crystal display 16 is referred to as “front side” as shown in FIG. The side toward the substrate box 24 is referred to as the “back side”.

  As shown in FIG. 2, the inverter board 18 is mounted on the back side of the liquid crystal display 16, and the liquid crystal display 16 and the inverter board 18 are covered and assembled with a cover member 20 so as to protect the liquid crystal display 16 and the inverter board 18. The assembled liquid crystal display 16, inverter board 18 and cover member 20 can be handled as a single display unit 26. Mounting boards 24 a and 24 b are provided on the front side of the substrate box 24. Usually, after the cooling fan 22 is attached to the mounting base 24b, the display unit 26 (or the cover member 20) is attached to the mounting base 24a. The cooling fan 22 corresponds to a cooling device.

  Here, the function and structure of each element described above will be briefly described. The front surface of the liquid crystal display 16 is a display surface 16a for displaying information, but the back surface and side surfaces thereof are covered with a shield member 16c. The shield member 16c corresponds to a conductive casing, is provided to prevent malfunction due to external noise and the like, and is generally electrically connected to ground. However, the connector 16b provided on the back side of the liquid crystal display 16 for mounting the inverter board 18 is not covered with the shield member 16c.

  The inverter substrate 18 corresponds to a power supply substrate that supplies power to the liquid crystal display 16. The inverter board 18 includes a connector 18c, a leaf spring 18a, a pedestal 18b and the like in addition to the electronic elements constituting the electronic circuit. In addition to the power supply function for supplying power to the liquid crystal display 16 by assembling the connector 18c and the connector 16b, the inverter board 18 relays a display signal to the liquid crystal display 16. Is realized. The leaf spring 18a is formed of a conductive material (for example, a metal material such as beryllium copper having strong elasticity), and has a conductive function and an elastic function. The base 18b is provided, for example, at one or more corners or the peripheral edge of the four corners of the inverter board 18 in order to ensure a space between the base 18b and the liquid crystal display 16. The pedestal 18b is in contact with the back side of the liquid crystal display 16 to be mounted in cooperation with the leaf spring 18a so that the inverter board 18 does not wobble after being mounted.

  The cover member 20 has a function of fixing the liquid crystal display 16, a function of protecting the liquid crystal display 16 and the inverter board 18, and a function of air when the cooling fan 22 is operated to cool the liquid crystal display 16 and the inverter board 18. Has a function to secure the flow. In order to realize the function of ensuring the air flow, the cover member 20 is provided with a large number of slits 20 a at positions facing the back surface of the liquid crystal display 16 and on the side surfaces. The slit 20a corresponds to a through hole.

[Example of installing an inverter board on the back side of a liquid crystal display]
A specific example of mounting the inverter substrate 18 on the back side of the liquid crystal display 16 will be described with reference to FIG. 3A is a side view showing the state before mounting, FIG. 3B is a side view showing the state after mounting, and FIG. 3C is a perspective view showing the state after mounting. Show.

  In FIG. 3A, in order to mount the inverter board 18 on the liquid crystal display 16, for example, the inverter board 18 may be brought close to the liquid crystal display 16 as shown by the arrow D2 and the connector 18c is assembled to the connector 16b. . A coupling force is generated by the assembly of the connector 16b and the connector 18c, and the wobbling is almost eliminated by the leaf spring 18a and the base 18b, and the inverter board 18 is mounted on the back side of the liquid crystal display 16. FIGS. 3B and 3C show the state of mounting in this way. In order to reliably maintain the electrical connection of the leaf spring 18a, it is desirable to solder the connecting portion 18d between the inverter board 18 and the leaf spring 18a as shown in FIG.

  By the way, the connector 16b and the connector 18c are located at a portion sandwiched between the liquid crystal display 16 and the inverter board 18. When the inverter board 18 is actually mounted on the liquid crystal display 16, the connector is visible when viewed from one side of the liquid crystal display 16 and the inverter board 18 (that is, the back side of the inverter board 18 or the front side of the liquid crystal display 16). Absent. In this case, it may be searched until the connector 18c is fitted into the connector 16b, and it takes time to assemble. Therefore, for example, as shown in FIG. 3C, a marker 16d is provided on the back side of the liquid crystal display 16. The operator simply attaches the four corners of the inverter board 18 to the positions of the four markers 16d, so that the connectors can be easily assembled even if the connectors are not visible. Therefore, no searching is performed until the connector 18c is fitted into the connector 16b, and the assembly time can be shortened.

[Arrangement of cooling fan]
4 to 6 show a completed state in which the cooling fan 22 is attached to the mounting base 24b of the board box 24 and the display unit 26 (or the cover member 20) is attached to the mounting base 24a. 4 is a perspective view, FIG. 5A is a front view, FIG. 5B is a plan view, FIG. 5C is a side view, and FIG. A cross-sectional view taken along line AA shown in FIG.

In the completed state shown in FIGS. 4 to 6, the cooling fan 22 is arranged on the back surface side of the liquid crystal display 16 and the inverter board 18 and substantially at the center. According to this arrangement, the cooling fan 22 sucks out the air inside the cover member 20. In addition, since the cooling fan 22 is not disposed on the side surfaces of the liquid crystal display 16 and the cover member 20, other devices (for example, an accessory) and members (for example, a ball passage) can be disposed. As shown in FIG. 6, the liquid crystal display 16, the inverter board 18, the cover member 20, the cooling fan 22, and the like in a completed state are attached to the game board 14 from the back side (the right side in the drawing).
In this example, an image control board 24c (corresponding to a circuit board) for controlling the contents displayed on the liquid crystal display 16 is enclosed in the board box 24, but other circuit boards used in the pachinko machine 12 such as a sub-control board. May be enclosed in the substrate box 24.

[Air flow during cooling]
The flow of air when the cooling fan 22 is operated is as indicated by arrows D4 and D6 shown in FIG. That is, it enters from the slit 20 a provided in the cover member 20 or the gap between the cover member 20 and the liquid crystal display 16. And it sucks out toward the cooling fan 22 from the slit 20a provided in the back side of the cover member 20, hits the substrate box 24, and diffuses. As shown in FIG. 6, a space 28 is formed between the back surface of the cover member 20 and the inverter board 18. Since the space 28 is formed in order to secure the air flow, the air flow generated during cooling becomes smooth, and heat generated from the liquid crystal display 16 and the inverter board 18 can be efficiently removed. it can.

[Effects of Examples]
According to the embodiment described above, the following effects can be obtained.
(1) The inverter board 18 is disposed in the space 28 formed by the cover member 20, and the cover member 20 is provided with a slit 20a through which air flows, and the slit 20a is provided on the back side and substantially in the center of the cover member 20 during cooling. The cooling fan 22 that flows air through is provided (see FIGS. 2 and 6B). The space 28 formed by the cover member 20 secures an air flow generated during cooling, and the liquid crystal display 16 and the inverter board 18 can be compactly arranged by effectively using the space 28, and the liquid crystal display 16 In addition, the entire inverter board 18 and the like can be cooled substantially uniformly. As a result of such arrangement, it is possible to arrange other devices (for example, an accessory) and members (for example, a ball passage) on the side surfaces of the liquid crystal display 16 and the inverter board 18. Furthermore, since the cover member 20 is structured to cover the back side and the side surface of the liquid crystal display 16 and the inverter substrate 18, it also functions to protect them.
The vectors along the rotation axis of the cooling fan 22 are arranged so that the normal vectors with respect to the surfaces of the liquid crystal display 16 and the inverter board 18 are substantially parallel {see FIG. 2 and FIG. 5B}. In this arrangement, when the thin liquid crystal display 16 or the cooling fan 22 is used, the front-rear direction (that is, the vector direction along the rotation axis of the cooling fan 22) can be made compact.
In this example, a slit 20 a (that is, a long hole) is applied as a through hole provided in the cover member 20. Instead of the slit 20a, air is allowed to flow even when a through-hole having an arbitrary shape such as a circular through-hole or a polygonal (for example, triangular or quadrangular) through-hole is applied. The above-described effects can be obtained as long as the through-holes can be used.

(2) The inverter board 18 is configured to include a data transmission function for relaying and transmitting data related to the content displayed on the liquid crystal display 16 and a power supply function for supplying power for operating the liquid crystal display 16. . According to this configuration, it is not necessary to separately provide a signal relay substrate, and the power supply function and the signal relay function are achieved only by providing the inverter substrate 18 on the back side of the liquid crystal display 16. Therefore, it is not necessary to perform an operation of installing a signal relay substrate, and the assembly work time can be shortened. This also applies to the power supply function.

(3) The cover member 20 is provided with a large number of slits 20a on the back surface and side surfaces {see FIGS. 2, 4, 5, and 6}. The slit 20a allows the air to flow reliably during cooling, thereby increasing the cooling efficiency.
Although a lot of dust is generated in the game hall, even if some of the slits 20a are clogged with the dust, the flow of air can be secured by the other slits 20a.

(4) The cooling fan 22 is configured to suck out the air inside the cover member 20 {see FIG. 2, FIG. 5B, etc.}. The heat generated in the liquid crystal display 16 and the inverter board 18 is likely to be trapped inside the cover member 20, but the air is guided to the cooling fan 22 so as to suck out the trapped heat toward the outside. Both the device 16 and the inverter board 18 can be cooled.
Since air containing dust is sent to the opposite side of the inverter board 18, a situation in which dust accumulates on the inverter board 18 does not occur, and failure due to dust accumulation (for example, short circuit) can be prevented.

(5) The inverter board 18 is provided with a conductive plate spring 18a. When the inverter board 18 is mounted on the back side of the liquid crystal display 16, the plate spring 18a comes into contact with the conductive casing covering the liquid crystal display 16. It was configured to be grounded (see FIG. 3). According to this configuration, simply by mounting the inverter board 18 on the back side of the liquid crystal display 16, the conductive leaf spring 18 a provided on the inverter board 18 contacts the casing of the liquid crystal display 16 and is grounded. . Therefore, it is not necessary to perform the work of attaching the lead wires, and the assembling work can be performed in a short time.

(6) The inverter board 18 includes a plurality of pedestals 18b that are placed on the casing (rear surface) of the liquid crystal display 16 to ensure a distance from the liquid crystal display 16, and at least one of the plurality of pedestals 18b. The base 18b is configured to be shared by the leaf spring 18a {see FIG. 3}. According to this configuration, the inverter substrate 18 can be stably mounted on the back side of the liquid crystal display 16 by the elastic force of the leaf spring 18a. Moreover, since the state in which the leaf spring 18a is in contact with the casing of the liquid crystal display 16 can be always maintained by the elastic force of the leaf spring 18a, the ground state can also be always maintained.

(7) When the connector 16b on the liquid crystal display 16 side and the connector 18c on the inverter board 18 side are assembled, the inverter board 18 is fixed to the liquid crystal display 16 by the coupling force of the assembly {see FIG. 3} . According to this configuration, it is not necessary to perform a fixing operation using screws or the like, so that the assembling operation can be performed in a short time.

[Other Examples]
As mentioned above, although the best form for implementing this invention was demonstrated according to the Example, this invention is not limited to the said Example at all. In other words, the present invention can be implemented in various forms without departing from the gist of the present invention. For example, the following forms may be realized.

(1) In the embodiment described above, the present invention is applied to the pachinko machine 12. Instead of this form, a gaming machine other than the pachinko machine 12 (for example, a slot machine, an arrangement ball machine, a sparrow ball game machine, a video game machine, etc.) provided with a liquid crystal display 16, an inverter board 18, etc. Similarly, the present invention can be applied to. Even in the other game machines, since the cooling is performed through the space 28 provided between the back side of the inverter board 18 and the cooling fan 22, the liquid crystal display 16, the inverter board 18 and the like can be arranged in a compact manner. Further, when the cooling is performed by the cover member 20, air is guided to the cooling fan 22 through the slit 20a to perform cooling, so that the liquid crystal display 16, the inverter board 18 and the like can be cooled substantially uniformly.

(2) In the above-described embodiment, the cover member 20 having a large number of slits 20a on the back surface and side surfaces is used {see FIG. 2, FIG. 5B, etc.}. Instead of this form, as shown in FIG. 7, the side surface may include a large number of slits 20 a, but the back surface may include a large number of slits 20 a only at a portion facing the cooling fan 22. In the cover member 20 shown in FIG. 2, a “short circuit phenomenon” is likely to occur in which the cooling fan 22 sucks out the air that has entered the space 28 inside the cover member 20 from the periphery of the cooling fan 22 through the slit 20 a. On the other hand, the cover member 20 shown in FIG. 7 does not have the slit 20a for sucking in from the outside except for the suction slit 20a in the immediate vicinity of the cooling fan 22, so that the short circuit phenomenon described above hardly occurs. Therefore, the heat generated in the liquid crystal display 16 and the inverter substrate 18 can be removed more efficiently, and the cooling efficiency can be further increased.

(3) In the above-described embodiment, the cover member 20 is provided with a distance L between the inverter board 18 (see FIG. 6). Instead of this form, a distance adjustment mechanism 30 for adjusting the distance L may be provided. For example, the distance adjusting mechanism 30 shown in FIG. 8 moves in the depth direction (that is, in the direction of the arrow D8 shown in the figure) and can move the distance L, and an adjusting member 30b (for example, adjusting the position of the movable piece 30a). Etc.). If the distance L is increased, the air flowing through the space 28 becomes gentler, and if the distance L is decreased, the air flowing through the space 28 becomes faster. If the air flows slowly, the heat that escapes per unit time decreases and the cooling rate decreases, and if the air flows quickly, the heat that escapes per unit time increases and the cooling rate increases. When the pachinko machine 12 is installed at a position where heat is difficult to escape, the distance L is narrowed to increase the cooling rate, and when the pachinko machine 12 is installed at a position where heat is easy to escape, the cooling rate may be low. L may be widened. Therefore, even if the operation of the cooling fan 22 is not controlled, the liquid crystal display 16 and the inverter board 18 can be efficiently cooled only by adjusting the distance L by the distance adjusting mechanism 30.

(4) In the above-described embodiment, the inverter board 18 is provided on the back side of the liquid crystal display 16, and the image control board 24c is sealed in the board box 24 that separates the cooling fan 22 from the inverter board 18 {FIG. See}. Instead of this form, when the liquid crystal display 16 has a built-in power supply function, an image control board 24c (or a board box 24 enclosing the image control board 24c) is provided on the back side of the liquid crystal display 16, and the The inverter board 18 (or the board box 24 enclosing the sub-control board or the like) may be arranged with the cooling fan 22 separated from the inverter board 18. According to this configuration, cooling can be performed by removing the heat generated from the liquid crystal display 16 and the image control board 24 c by the cooling fan 22.
