The variable display device 8 displays three display symbols (identification information) on the left, middle, and right in the display area. For example, numbers “0” to “9” and alphabet letters “A” to “E” are assigned to these display symbols.
[0040]
When there is a winning game ball at the start port 16, the variable display device 8 sequentially displays the display symbols composed of the numbers and characters described above. When a winning at the start port 16 is made at a predetermined timing (specifically, when the special symbol random number counter value at the time of winning detection is a winning value), it is a big hit state and three display symbols are arranged. Stop in state (big hit symbol). At this time, the large winning opening of the variable winning apparatus 10 opens wide for a predetermined time (for example, 30 seconds), and a large number of game balls can be acquired.
[0041]
The winning of the game ball to the start port 16 is detected by a special symbol start sensor 52. The passing timing of the game ball (specifically, the value of the special symbol random number counter provided in the game control device 100 (see FIG. 2) at the time of winning detection) is used as the special symbol winning memory and the game control device 100.

[0052]
A display control device 150 that controls the variable display device 8 is disposed almost at the center of the back side of the game board 6. As will be described later, the display control device 150 has an insulating property in the substrate case 160 that can be visually recognized from the outside. The insulating oil 180 as a liquid is filled, and the substrate 151 is housed in the substrate case 160 and immersed in the insulating oil 180. The display control device 150 and the power supply device 250 are covered with the protective cover 40, and a part of the protective cover 40 is notched in the drawing.
[0053]
FIG. 3 shows a front view of the display control device 150, and FIG. 4 shows an exploded view of the display control device 150.
[0054]
The display control device 150 accommodates the control substrate 151 on which the CPU 152 is disposed in a substrate case 160 made of a transparent (or transparent material that can be visually recognized inside), and is cooled in the substrate case 160. The medium is filled with oil 180 having insulation and translucency (predetermined transparency), and the front and back of the control board 151 are immersed in the insulating oil 180 from the bottom of the board case 160 to a predetermined position. The control board 151 is configured to be visible from the outside of the board case 160 through the board case 160 having predetermined translucency (transparency) and the insulating oil 180. The insulating oil 180 also functions as a heat conduction medium that transmits heat released from the heat generating portion to the surface of the substrate case 160.
[0055]
The control board 151 has the CPU 152 arranged at the lower part of the board, and the lower end of the control board 151 is supported by a plurality of bases 172 installed on the inner peripheral bottom of the board case 160. The left and right end portions of the control board 151 are guided by guides 171 and 171 fixed to the inner peripheral side of the board case 160 and are accommodated at predetermined positions.
[0056]
The upper end portion of the control board 151 protrudes to the outside through a lid 162 provided on the upper part of the board case 160, and another control device or the variable display device 8 is placed on the upper part of the control board 151 protruding from the board case 160. A connector 153 is provided for connection to the.
[0057]
As will be described later, the control board 151 is sandwiched between the lids 162 to prevent the insulating oil 180 in the board case 160 from leaking. For this reason, the control board 151 is formed on the upper part of the control board 151 that contacts the lid 162. 4 includes a component non-mounting region 154 in which no component is arranged as shown in FIG.
[0058]
In the component non-mounting region 154, in addition to prohibiting the placement of components, by prohibiting the placement of through holes, prohibiting silk printing, etc., a smooth surface is formed and the substrate is in close contact with the lid 162. It is comprised so that the sealing performance in case 160 may improve.
[0059]
Next, the substrate case 160 is formed of a translucent member (for example, transparent acrylic or glass), and is configured so that components on the control substrate 151 are visible. The substrate case 160 does not need to be entirely formed of a light-transmitting member. It is sufficient that at least the component mounting surface (the surface on which the CPU 152 or the like is disposed) of the control substrate 151 is visible. The transparency is not limited as long as the components on the control board 151 can be visually recognized, and may be configured by a member colored translucent or translucent. Note that the light-transmitting member may be formed of a material having sufficient light transmittance and having a transparency and a refractive index such that the surface of the substrate can be clearly recognized.
[0060]
Here, the substrate case 160 mainly includes the case main body 161 that fills the insulating oil 180 and the lid 162 that seals the inside, while accommodating most of the control substrate 151.
[0061]
An opening 163 that can be coupled to the lid 162 is provided at the upper end of the case main body 161, and a bottom is formed at the lower end of the case main body 161. The case body 161 is coupled to the back surface of the gaming machine via a plurality of brackets 164 provided on the outer peripheral side. The board case 160 is attached to the back surface of the gaming machine in such a direction that the component mounting surface of the control board 151 is visible on the back surface of the gaming machine.
[0062]
As shown in FIGS. 3 and 5, an injection part 190 made of a cylindrical member is fixedly provided on the upper portion of the control board 151 in order to inject or supplement the insulating oil 180.
[0063]
The injection unit 190 is formed of a light-transmitting cylindrical member so that the internal oil level can be visually recognized. The upper end is opened, and a removable cap 191 is provided at the upper end. The cap 191 is removed. Insulating oil 180 is injected in this state, and usually sealed with a cap 191. The cap (insulating liquid injection portion) is difficult to open again by screwing with a one-way screw, welding of a resin member, adhesion, or the like. Or you may make it leave the evidence of opening like a plastic bottle cap.
[0064]
FIG. 5 shows a cross section of the substrate case 160 including the injection part 190. In the lower part and the central part of the injection part 190, through holes 193 and 194 communicating with the case main body 161 are formed, and the lid 162 is closed. In the case of injecting the insulating oil 180, the insulating oil 180 is injected from the lower through hole 193, and the air due to the rise in the liquid level is discharged from the through hole 194.
[0065]
Further, a scale 192 indicating the reference value (reference liquid level) of the liquid level of the insulating oil 180 is provided at a position visible from the back of the gaming machine, and management is performed so that the liquid level of the insulating oil 180 exceeds the scale 192. To do. Further, the scale may be provided not only on the injection portion 190 but also on the outer periphery of the case main body 161. For example, the scale may be provided on the entire periphery of the case main body 161 like a scale 192A shown in FIGS.
[0066]
Here, the insulating oil 180 filled in the substrate case 160 is a synthetic oil (for example, silicone oil, rapeseed ester oil, poly-α-olefin oil, etc.), mineral oil, etc., and has a predetermined transparency. . The predetermined transparency may be such that the shape, mounting state, or identification information (for example, model number, chip ID) of the CPU 152 and other ICs mounted on the control board 151 from the outside of the case body 161 is visible. .
[0067]
Further, the insulation required for the insulating oil 180 may be a resistance value that can operate in the same manner as in the atmosphere without causing a short circuit between the circuits and terminals of the control board 151. Here, the insulating oil 180 is applied as the insulating liquid. However, the insulating oil 180 is not limited to oil, and any liquid having insulating properties and predetermined transparency may be used.
[0068]
Further, the capacity of the insulating oil 180 filled in the board case 160 can be a target of the heat conductivity of the oil and the case body 161 and the heat generation amount (or power consumption) of the entire control board 151, or a heat-generating component or unauthorized work. What is necessary is just to set according to the mounting position of components.
[0069]
Next, the structure of the lid 162 that seals the inside of the case main body 161 will be described with reference to FIGS.
[0070]
In FIG. 6, the lid 162 is divided into a lid 162A and a lid 162B so as to sandwich the front and back of the control board 151. One lid 162B has a plate thickness and an overall width (horizontal direction in FIG. 6). ) Is formed in a substantially “U” shape, and a seal member (oil seal) 201 is attached to the end surface of the lid 162A facing the control board 151 and the lid 162B. A "U" -shaped seal member 202 is attached to the notch 169 of the lid 162B facing the substrate 151, and the control board 151 is fitted into the notch 169 and then sandwiched between the lids 162A and 162B. Insulating oil 180 is prevented from leaking from the joint between control board 151 and lid 162 projecting to the outside.
[0071]
That is, when the substrate case 160 is constituted by a box and a lid, a sealing member (leakage prevention member) is provided at a contact portion between the box and the lid to prevent leakage of the internal insulating oil 180. It is. In the case where a plurality of lids are provided, the signal line or the control board may be sandwiched between the plurality of lids. In this case, the lid is provided with a seal member at a contact portion with the signal line or the control board. The box is configured such that the electronic component mounting surface when the control board is accommodated is transparent (or has a predetermined transparency).
[0072]
6 and 7, flanges 165 and 166 protrude from both ends of the lids 162A and 162B (left and right ends in the figure) at positions facing each other. Further, a hole 165A is formed through the flanges 165 and 166 at the same coaxial position, and the bolts 141 inserted through the holes 165A are fastened so that the pair of lids 162A and 162B sandwich the control board 151 and are integrated. Combine to form one lid 162.
[0073]
Next, as shown in FIGS. 6 and 7, the lid 162 and the case main body 161 are coupled with flange portions 168 and 168 in the horizontal direction from the left and right ends of the opening 163 of the case main body 161. The lid 162A is also provided with flange portions 167 and 167 at positions facing the flange portion 168 of the case body 161 (both ends of the lid 162A). Further, a hole 168A is formed at the coaxial position in the flange portions 167 and 168, and a lid 162 sandwiching the control board 151 is coupled to the case main body 161 by a bolt 142 inserted through the hole 168A. A seal member 203 is interposed between the lid 162 and the case main body 161 to prevent the insulating oil 180 from leaking from the joint between the case main body 161 and the lid 162, and to insulate the case 160. The sexual oil 180 is enclosed.
[0074]
The effect | action by the above structures is demonstrated below.
[0075]
First, as shown in FIG. 5, since the front and back of the control board 151 are immersed in the insulating oil 180, the heat generated by the elements on the board such as the CPU 152 is transmitted to the insulating oil 180. Then, the heat transmitted to the insulating oil 180 is released into the atmosphere through the case main body 161. Therefore, even if the arrangement of the control board 151 is not necessarily a place suitable for cooling, such as on the back of a gaming machine, a heat radiating member is provided on the surface of the element such as a heat sink by radiating heat in the entire board case 160. Therefore, the CPU 152 can be surely cooled, and a variety of effects can be realized using the high-performance CPU 152.
[0076]
Further, since the heat generation amount (for example, the CPU 152) on the control board 151 is provided in the lower part of the control board 151, the insulating oil 180 is placed on the upper side from the bottom of the case body 161 as shown by the arrows in FIG. It is possible to generate convection toward the bottom after heading toward the bottom, so that heat can be uniformly dissipated and cooling performance can be improved.
[0077]
In addition, since the front and back surfaces of the control board 151 are each cooled by the insulating oil 180, the cooling performance can be improved as compared with the case where only a single surface is cooled. Since the gap is provided between the bottom surface of the case body 161 and the support body 172, if the temperature difference between the front and back surfaces of the control board 151 is large, the insulating oil 180 is placed between the front and back surfaces of the control board 151. Convection is generated and the cooling performance can be improved.
[0078]
In addition, since the board case 160 and the insulating oil 180 have translucency (predetermined transparency), the board 151 and the elements on the board 151 can be seen from the back of the gaming machine. Even if it is replaced with a substrate, it can be easily discovered, and unauthorized acts can be suppressed, so that both fraud prevention and securing of cooling performance can be achieved.
[0079]
The cap 191 may be removable, and a scale 192 may be provided in the injection portion 190 of the insulating oil 180 so that the reference value can be easily confirmed. In this case, when the liquid level is lowered Can quickly replenish the insulating oil 180 to maintain the cooling performance. However, when replenishment of the insulating oil 180 is assumed as described above, it is desirable to use a special sealing method (use of a special tool or the like) in order to achieve compatibility with fraud countermeasures.
[0080]
Furthermore, if the board is replaced with an unauthorized board or an unauthorized part is attached, the liquid level changes when the volume of the authorized board is different from that of the unauthorized board. Comparing the liquid level with a reference value can also assist in finding fraud.
[0081]
If the board is replaced with an unauthorized board, the legitimate board is pulled out with the insulating oil 180 attached to it, so there is a very high possibility that the insulating oil 180 will sag on the back of the gaming machine or the floor surface. It is possible to easily determine whether or not the substrate is illegally replaced based on the state of oil leaked to the periphery in addition to the decrease of
[0082]
It should be noted that by adding a predetermined odor to the insulating oil 180, it is possible for a store clerk or the like of the game store to easily know that the lid 162 of the case 160 has been unlawfully opened, and to further deter unauthorized acts. It becomes. However, since the lid 162 seals the case main body 161 in a normal state, no odor leaks to the outside.
[0083]
It is desirable that the predetermined odor to be added to the insulating oil 180 should not be felt in normal gaming machines or amusement stores such as food odors or flower scents. The game store side can easily detect fraud.
[0084]
In addition, since only the connector 153 for connecting the control board 151 and another control device is protruded from the board case 160, each control device can be quickly replaced, and repair work and the like can be performed as in the conventional case. Can do.
[0085]
FIG. 8 shows a second embodiment, in which the entire control board 151 of the first embodiment is housed in a case 160, and a connector is provided on the lid of the board case 160. This is the same as in the first embodiment.
[0086]
The entire control substrate 151 ′ is accommodated in the substrate case 160, and almost entirely immersed in the insulating oil 180.
[0087]
The lid 162 ′ of the case body 161 is provided with a connector 153 for connecting to another control device or the power supply device 250. The connector 153 and the control board 151 are connected by a flat cable 155 or the like.
[0088]
By connecting the flat cable 155 by soldering or the like on the control board 151 side, the control board 151 ′, the lid 162 ′, and the connector 153 can be integrated. As a result, even if an unauthorized substrate is to be mounted in place of the control substrate 151 ', the lid 162' needs to be replaced, which makes it difficult to perform unauthorized substrate replacement work.
[0089]
In addition, as shown in FIG. 9, a flat cable 155 provided with a connector 153 at the tip may be pulled out from the lid 162 ′. In this case, if the flat cable 155 and the lid 162 ′ are coupled via a seal member or the like, Good.
[0090]
FIG. 10 shows a third embodiment, in which only the front surface of the substrate case 160 of the first embodiment is formed of a translucent member, and the other surface is a heat radiating portion (for example, a metal having good thermal conductivity). It is composed.
[0091]
A front surface 160F of the substrate case 160 '(a surface visible from the back of the gaming machine) 160F is formed of a light-transmitting member as in the first embodiment.
[0092]
On the other hand, the side surface 210, the bottom surface 220, and the back surface are formed of a member having good thermal conductivity (for example, a metal member) to form a heat radiating portion. Further, cooling fins 211 are provided on the side surface 210 to enhance heat dissipation performance.
[0093]
The control board 151 needs to be visually recognized because the component mounting surface of the control board 151 (the side provided with the CPU 152 as the heating element) can be easily seen when the gaming machine 1 is opened and the back surface is viewed. Only the front surface 160F facing the component mounting surface may be formed of a translucent member such as transparent acrylic, that is, a visible member having a predetermined transparency.
[0094]
On the other hand, visibility is not required for other surfaces. Therefore, these surfaces are formed of a heat radiating member (metal having high heat conductivity, etc.) with good heat dissipation without considering visibility, and heat generated from the control board 151 is transferred to the insulating oil 180. The heat further transmitted to the insulating oil 180 is formed as a heat radiating portion and is transmitted from the side surface 210 and the bottom surface 220, cooled by the atmosphere, and effectively exhausts the heat generated from the control board 151. Visibility can be ensured while improving the cooling performance of the substrate case 160 by reliably cooling the heating element. Furthermore, by providing the cooling fins 211 on the surfaces made of these metals, the cooling performance can be further improved. In particular, when a high performance CPU 152 is adopted, a stable operating environment is prevented by preventing malfunction due to overheating. Therefore, it is possible to achieve both ensuring visibility and improving cooling performance.
[0095]
In the above embodiment, the case where the present invention is applied to the display control device 150 has been shown. However, any control board disposed in the gaming machine 1 can be applied. For example, in FIG. You may apply to the apparatus 100, the power supply device 250, the discharge control apparatus 400, etc.
[0096]
Moreover, although the case where it applied to the pachinko machine as a game machine was shown in the said embodiment, as shown in FIG. 11, the game control apparatus 100 'and power supply device 250' of the pachislot machine 1 'provided with variable display apparatus 8'. In the same manner as described above, both fraud prevention and substrate cooling can be achieved at the same time.
[0097]
In the above-described embodiment, an example is shown in which the game control device is configured from a plurality of control devices such as the game control device 100, the display control device 150, and the discharge control device 400. The control device may be applied to a control device integrated on a single substrate, and the same operations and effects as in the above embodiment can be obtained. Alternatively, even if a plurality of control boards are accommodated in one board case 160, the same effect can be obtained.
[0098]
The substrate case 160 is sealed with an insulating liquid inside, and may be provided with an opening detection means for detecting that the sealed state of the substrate case 160 is released at a predetermined position of the case. By providing this, it is possible to easily know that the case has been opened, which helps when discovering fraud. As the unsealing detection means, if a paper piece or the like is arranged on the outer periphery of the substrate case 160 (for example, in the vicinity of the opening 163), the substrate case 160 or the lid 162 is opened and the control substrate 151 is taken in and out. Since the insulating oil 180 spills around and adheres to the paper piece, evidence of opening can be obtained.
[0099]
Further, as the opening detection means, a member for detecting that the outside air is touched inside the case 160 may be disposed. For example, if silica gel as a moisture absorbent is disposed inside the lid 162, During the period in which the lid 162 is opened, the color changes due to moisture absorption (for example, pink whose moisture absorption capacity decreases from blue in the dry state), so that the opening can be detected based on the color of the moisture absorbent material. When the moisture absorbent material is assembled to the lid 162, discoloration due to deterioration with time can be suppressed and the detection accuracy of opening can be improved by performing the operation in a low humidity environment.
[0100]
In addition, the insulating liquid may be given a predetermined color, and when performing an illegal act, it is necessary to replenish the spilled insulating liquid, so that the illegal act can be suppressed. By comparison with the machine, an abnormality can be detected from the color difference of the insulating liquid.
[0101]
Further, the insulating oil 180 may have a predetermined viscosity in order to prevent a decrease in liquid level and a decrease in the visibility of the control board 151 due to spillage or foaming during transportation.
[0102]
In the above embodiment, the lid 162 is provided on the upper portion of the case body 161, the injection portion 190 of the insulating oil 180 is provided upward from the case body 161, and the cap 191 is attached to the upper end thereof. When the substrate case 160 is attached, it may be attached so that the lid 162 and the injection part 190 face downward. In this case, it is not easy to perform unauthorized work, and it is possible to suppress unauthorized actions.
[0103]
In the above embodiment, the board case 160 has a sealed structure. However, during transportation, the board case 160 is sealed to prevent leakage of the insulating oil 180, and after being attached to a gaming machine, the inside and outside of the board case 160 can be ventilated. Also good.
[0104]
Moreover, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
