It is a perspective view which shows the sub control apparatus in another embodiment, and a display control apparatus. It is a perspective view which shows the sub control apparatus in another embodiment, and a display control apparatus.

As described above, conventionally, on the back side of a gaming machine such as a pachinko machine, various control devices for performing various controls relating to the game, a payout mechanism for paying out gaming balls, etc. are arranged vertically and horizontally. It is done. The control device may be, for example, a main control device that performs overall control of a game, a payout control device that controls a payout device of gaming balls, a display control device that controls a display device for performing display effects, speakers, lamps, etc. An audio lamp control device or the like to control is provided.

In recent years, various electronic components mounted on a control substrate tend to increase as the performance of electronic components such as central processing units (CPUs) constituting the main control unit of the control device increases and the amount of control data increases. Therefore, the size of the control substrate and thus the size of the resin case (substrate box) that accommodates the control substrate also tends to increase. For example, a liquid crystal display device or the like is adopted as a display device, and the liquid crystal display portion tends to be gradually enlarged in order to improve the interest, so that a display control device integrated with the liquid crystal display portion is integrated. The size is also increasing in proportion to the liquid crystal display unit. Therefore, the occupied area occupied by the display device (display control device) is also increasing on the back side of the gaming machine, and other control devices must be installed to avoid the installation space of the display device. The current situation is that it has become difficult.

In addition, many cable connectors are also wired on the back side of the gaming machine to electrically connect the control devices with each other or various electric components such as the ball entry detection device and the variable winning device. . Each control device is provided with a terminal portion to which a connector of a cable connector is connected (see, for example, Patent Document 1).

However, in recent years, various malicious acts relating to the control device and the like have become a problem. In particular, in recent years, malicious acts such as so-called "hanging" have become prominent, for example, attaching a separate substrate to a cable connector or a terminal portion.

On the other hand, it is also conceivable to provide a cover for covering the back side of the gaming machine and to make it difficult to remove the connector connected to the terminal of the control device. However, in this case, if the cover is not placed as close as possible to the control device, the effect is thin.

However, if the cover body is disposed close to the control device, the gap between the two becomes narrow, and the cable connector can be wired if, for example, the cable is not bent excessively at the corners of the control device (substrate box) or the like. There is a risk of disappearing. Also, in general, the cable length of the cable connector is set with some allowance in consideration of the connection work with the terminal of the control device, etc., so the cover with the cable surplus portion forcibly bent There is also the possibility of being accommodated between the body and the control device. As a result, there is a concern about the adverse effect on the cable connector.

In particular, when a large number of devices such as control devices are installed in a limited installation space and the control devices are disposed close to each other, or when the cable of the cable connector consists of a plurality of wires, relatively thick ones, etc. In the case of using or the like, the above problem is more likely to appear.

The above problem is not limited to the back side of the gaming machine, but also applies to other gaming machines in which many devices such as a control device are installed in a limited installation space. That is, the problem is not limited to the above-described pachinko machine, but also applies to other gaming machines such as slot machines.

The present invention has been made to solve the above-described problems, and an object thereof is to provide a gaming machine capable of effectively using an installation space of a control device etc. and suppressing fraudulent acts. is there.

  Hereinafter, each means suitable for solving the said subject etc. is itemized and demonstrated. In addition, specific effects and the like are added to the corresponding means as needed.

Means 1. It is a gaming machine that draws a lottery based on a predetermined opportunity, and generates a special gaming state advantageous to the player when a winning result is obtained by the lottery,
A first substrate box containing a first control substrate (main control substrate) and a second substrate box containing a second control substrate (sub control substrate);
The first substrate box and the second substrate box respectively face the front wall portion disposed opposite to the mounting surface of the control substrate on which various electronic components are mounted, and the back surface of the control substrate. It has a substantially box-like shape including a back wall portion to be disposed and a peripheral wall portion disposed opposite to the peripheral portion of each of the control boards, so that the mounting surfaces of both the control boards face in the same direction. In the gaming machine, which is disposed side by side vertically or laterally, and in which part of the peripheral wall portion is disposed adjacent to each other so that the positions of their positions in the front-rear direction overlap with each other,
The first control board is provided with a terminal portion for transmitting or receiving a signal to / from an electric component outside the first control board on the mounting surface, and the terminal portion is exposed. Housed in the first substrate box,
A cable connector electrically connected to the electrical component is drawn from the back side of the two board boxes to the front side of the two board boxes through the gap between the two board boxes, and the connector of the cable connector is 1 is configured to be connected to the terminal portion of the control board,
It is disposed to face at least a part of the front wall portion of the first substrate box and the second substrate box, and is connected to the terminal portion at least at a position facing the terminal portion of the first control substrate A cover body covering the removal direction side of the connector of the cable connector,
In at least a part of the peripheral wall portion and the connecting portion of the front wall portion on the side adjacent to the first substrate box in the second substrate box, a chamfered portion inclined with respect to the peripheral wall portion and the front wall portion is formed A game machine characterized in that a relief portion is formed to allow bending of the cable of the cable connector.

  According to the above means 1, the terminal portion and the connector of the cable connector connected to the terminal portion are covered by the cover body. Therefore, even if you try to perform a vicious act such as attaching a so-called hanging board or replacing the control board with a fraudulent product after illegally removing the connector, the cover body is not removed unless the cover body is removed. Such an action can be deterred because it is obstructive and the removal of the connector is difficult.

  Further, according to the above-described means, the corner of the second substrate box adjacent to the first substrate box is chamfered to provide a space for allowing the cable to bend, that is, a clearance. As a result, even when the first board box and the second board box are disposed adjacent to each other, the cable connector can be bent with a margin and can be wired without excessively bending the cable connector, so that an adverse effect on the cable connector can be reduced. As a result, the cover body can be disposed closer to both the substrate boxes, so that the fraud suppression effect can be further improved. When the position of the external electric component or the position of the terminal portion thereof is different from the position of the terminal portion of the control board connected to the electric component etc. via the cable connector in the left-right direction, the cable connector may be used. Since the bending in the left and right direction is also added, the cable connector is more easily bent, and the above-mentioned failure is more likely to appear. Therefore, under such a configuration, the above means is more effective.

  As a result, it is possible to effectively use the installation space of the substrate box and the like, and to suppress fraudulent acts.

  The relationship between the first substrate box and the second substrate box can be applied not only to the one-to-one relationship but also to the one-to-many relationship. That is, the present invention can be applied in a configuration in which the second substrate box is disposed on at least one of the upper, lower, left, and right sides of the first substrate box. For example, it is possible to correspond to a configuration in which one substrate box is provided on the upper side of the first substrate box and one substrate box is provided on the left side.

  In addition, in order for both substrate boxes to be disposed "parts of the peripheral wall portions are adjacent to each other", it goes without saying that the peripheral wall portions of both substrate boxes are arranged in close proximity to each other. The case is also included.

  In addition, as the above-mentioned “the external electric component of the first control board”, for example, the above “second control board”, “the ball control means which is provided in the game area and causes the special game state advantageous to the player to be generated. The ball detecting means provided correspondingly, "the driving means provided corresponding to the variable winning device provided in the game area and activated when generating the special game state advantageous to the player," The "relay board" etc. which relay parts are mentioned.

  Means 2. The gaming machine according to the means 1, wherein a distance between the connector and the cover body is set to be shorter than a distance (insertion amount) necessary for removing the connector.

  According to the above means 2, unless the cover body is removed, the connection of the connector of the cable connector can not be released, and the fraud suppression effect of the above means 1 is more reliably exerted.

  Means 3. The gaming machine according to the means 1 or 2, further comprising a guide portion for guiding the cable to the side of the chamfered portion.

  According to the above means 3, by providing the guide portion, the cable can be guided in the direction opposite to the chamfered portion, that is, in the direction opposite to the first substrate box to promote the cable to be in a curved state. The bending suppression effect of the above means 1 is more reliably exerted.

Means 4. And an air blowing means for blowing air toward the inside of the second substrate box.
The gaming machine according to any one of the means 1 to 3, wherein an exhaust port is provided at a chamfered portion of the second substrate box.

  Generally, electronic components such as CPUs mounted on a control substrate are accompanied by heat generation, so conventionally in a control device, for example, heat generated from electronic components such as providing a heat dissipation hole in a substrate box housing the control substrate Various heat dissipation measures are taken to release the heat efficiently.

  Further, in recent years, due to diversification of the rendering function and the like, higher-performance electronic components such as a CPU having a high processing speed have been mounted on the control substrate. For example, a CPU having a high processing speed, an image processing apparatus (VDP), and the like are mounted on a display control substrate that controls a liquid crystal display device or the like, and more versatile display effects are possible.

  Generally, 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 heat generated is also increased. As described above, when a large amount of heat is generated in the resin case, the heat can not be sufficiently dissipated only by the above-described heat dissipation hole, 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 measures for heat dissipation are required, such as attaching a blowing means such as a cooling fan.

  However, since many devices such as a control device are installed in a limited installation space in the gaming machine, the game machine approaches (or comes into contact with) a predetermined control device (substrate box) provided with the above-mentioned air blowing means. Other control devices may be deployed. In this case, if the installation distance between the two is too narrow, sufficient ventilation space can not be secured, and it is also concerned that efficient exhaustion can not be performed from the exhaust port opened in the near side wall surface of the control device equipped with the blower. Be done.

  In view of such a problem, when the control devices are disposed close to each other, it is conceivable to shift the control devices back and forth to secure the ventilation space, but the space of the island facilities of the game hall where the game machine is installed Due to this, there is a limit to expanding the installation space of the control device etc. in the depth direction. That is, when installing many devices such as a control device on the back side of the gaming machine, it is desirable to arrange these various devices more compact not only in the vertical and horizontal directions but also in the front and rear direction. Also, in order to increase the size of the control board or to ensure expandability for adding new devices, when a plurality of control devices are provided side by side, their positions in the longitudinal direction as far as possible It is preferable to align the two in order to arrange them efficiently without waste, and to prevent the mechanism on the back side of the gaming machine from expanding in the depth direction.

  In this respect, according to the means 4, by providing the air blowing means for blowing air toward the inside of the second substrate box, for example, a predetermined electronic component such as an electronic component emitting high heat such as a CPU can be provided in the second substrate box. It is possible to intensively blow outside air that is cooler than air and to efficiently cool the electronic component.

  Furthermore, in the second substrate box provided with the air blowing means, by providing the chamfered portion and the exhaust port opened there in the portion adjacent to the first substrate box, the adjacent first substrate box is not disturbed. Sufficient ventilation can be ensured. As a result, exhaust can be performed efficiently, and a decrease in heat radiation performance can be suppressed.

  In addition, the exhaust port can be omitted from the peripheral wall portion of the portion adjacent to the first substrate box. In this way, the hot air is not blown to the adjacent first substrate box, so the influence on the adjacent first substrate box (first control substrate) can be reduced. Furthermore, since it is not necessary to secure a ventilation space between the adjacent first and second substrate boxes, it is also possible to bring the two substrate boxes into close contact. However, in this case, it is necessary to form a gap portion through which the cable connector is inserted. As a result, it becomes possible to expand both substrate boxes until they abut each other, and it is possible to cope with an increase in size of the control substrate and to effectively use a limited installation space.

  As a result, it becomes easy to secure a larger space for installing both substrate boxes without impairing the heat radiation performance of the second substrate box.

  Of course, since it is not necessary to shift and arrange | position both board | substrate boxes in the front-back direction, effective use of the installation space in the front-back direction can be aimed at. That is, expansion of the installation space of the substrate box and the like in the depth direction can be suppressed, and the substrate box and the like can be disposed more compactly and efficiently without waste. As a result, it is possible to cope with the case where the installation space of the island facilities of the game hall where the game machine is installed is relatively narrow, while securing the expandability for adding new devices.

Means 5. The air blowing means is disposed opposite to the mounting surface of the second control board, and
The gaming machine according to the means 4, wherein the cover body covers a range in which the air blowing means is provided.

  According to the means 5, the external air can be efficiently applied to the electronic component mounted on the second control substrate. In addition, the cover body is disposed opposite to the air blowing means on the front wall portion of both substrate boxes, that is, on the intake side of the air blowing means, so that foreign matter such as dust and dirt enters the second substrate box. It can be suppressed. As a result, it is possible to achieve both suppression of the entry of foreign matter such as dust and dirt and improvement of the cooling efficiency of the electronic component.

  Means 6. The air blowing unit is disposed opposite to a specific electronic component among the electronic components mounted on the second control substrate, and blows air toward the specific electronic component. Gaming machine.

  According to the above-mentioned means 6, since it is possible to intensively cool a specific electronic component, it is possible to efficiently keep the specific electronic component at an appropriate temperature.

  Means 7. The gaming machine according to any one of the means 4 to 6, wherein the cover body covers a range in which the chamfered portion is provided and has an exhaust hole corresponding to the exhaust port.

  As described above, when the cover body is disposed close to both the substrate boxes and the connector is not removed, the exhaust performance (heat dissipation performance) may be degraded. In this respect, according to the above-mentioned means 7, by providing the exhaust hole in the cover body, it is possible to suppress a decrease in the exhaust performance from the exhaust port of the chamfered portion.

  Means 8. The first substrate box and the second substrate box are disposed such that the front-rear direction positions of the front wall portions are the same or substantially the same. The gaming machine described.

  In the configuration like the above means 8, since the gap with the cover body is particularly hard to occur, the effect of the above means 1 will be more effective. Moreover, both substrate boxes can be arranged more compactly. If the front and rear widths of both board boxes are different, or if the front wall of both board boxes does not fit due to structural reasons such as arrangement, arrange spacers on the back side of one board box. Therefore, the positions of both front wall parts will be aligned. At this time, in some cases, a relatively large space can be secured on the back side of one substrate box. In this case, for example, it becomes easy to cope with the case where a new device is added, etc., and the versatility becomes high when changing the model of the gaming machine or the like. That is, by aligning the front wall portions of both substrate boxes, both substrate boxes can be arranged more compactly, and the space on the back side of one substrate box is effective while suppressing the expansion of the installation space in the depth direction. It can be used to

  Means 9. The gaming machine according to any one of the means 1 to 8, wherein the first control board is a main control board that performs overall control of a game.

  The main control board of the above-mentioned means 9 is a control board which has the greatest influence on the control of the gaming machine, so the effect of avoiding heat exhaust from other board boxes as described above and the deterrence effect of cheating are more effective. It will be.

  Means 10. The gaming machine according to any one of the means 1 to 9, wherein the first substrate box is a substrate box provided with sealing means.

  According to the above means 10, if the first substrate box is unsealed, some trace remains on the sealing means, and the fraud can be easily found by confirming it. Therefore, it is possible not only to directly prevent fraud but also to deter fraud from the aspect of being able to detect fraud early.

  In addition, on the front side of the base plate 645, a window frame 649 is disposed, in which the liquid crystal display 647 and the protective panel 648 are engaged in a superimposed state. The window frame 649 is locked to a unit cover 654 described later.

  On the other hand, the display control device 45 includes a display control substrate 650 on which various electronic components are mounted, and the display control substrate 650 is attached to the back side of the base plate 645. A unit cover 654 made of a transparent resin material or the like is attached to the back side of the base plate 645 so as to cover the display control substrate 650. Accordingly, the base plate 645 and the unit cover 654 constitute a substrate box that accommodates the display control substrate 650. The said board | substrate box corresponds to the 2nd board | substrate box in this embodiment. That is, the display control substrate 650 corresponds to the second control substrate in the present embodiment.

  Unit cover 654 has a substantially rectangular back wall portion 655 formed substantially flat opposite to the mounting surface of display control substrate 650, and upper, lower, right, and left formed along the peripheral portion of back wall portion 655. A side wall portion 656 is formed, and the base plate 645 side is formed in a substantially box shape having an opening surface. The back wall 655 corresponds to the front wall of the second substrate box in the present embodiment, the base plate 645 corresponds to the back wall, and the side wall 656 corresponds to the peripheral wall.

  In the back wall portion 655 of the unit cover 654, a terminal portion window 660 for exposing the terminal portions 658 and 659 provided on the display control substrate 650 to the outside is formed. The connector of the cable connector or the like to the terminal portions 658 and 659 of the display control board 650 can be inserted and removed from the outside of the display control device 45 through the terminal portion window 660.

  At the upper, lower, left, and right side wall portions 656 of the unit cover 654, a small hole group 662 for ventilation is formed. In the present embodiment, the small hole group 662 functions as an exhaust port. As can be seen from FIG. 11 and the like, there are two types of small holes constituting the small hole group 662, small circular small holes 662a and larger long holes 662b. This is from the viewpoint of prevention of occurrence of failure etc. and fraud prevention, and in the case where an electronic component which foreign objects etc. do not want to contact is arranged in the vicinity of sidewall 656, circular small hole 662a corresponding to the location Is provided. Further, the small hole group 662 may not be formed, for example, when a more important electronic component such as a CPU 521 or a VDP 526 described later is disposed in the vicinity of the side wall portion 656.

  In addition, many apparatuses are installed in the pachinko machine 10 in the limited installation space of the back side so that FIGS. 5-7 may also show. For this reason, various devices are disposed adjacent to each other. For example, the main control device 261 is disposed adjacent to the lower side of the display control device 45. As shown in FIG. 7, in the present embodiment, since the installation space between the two is relatively narrow, a sufficient ventilation space can not be secured, and the small holes 662 (see FIG. 12) of the lower side wall portion 656 of the unit cover 654. There is also concern that it is not possible to exhaust efficiently.

While forming the inclined wall part 665 as a chamfer in the connection part with 656, in the said inclined wall part 665, the diagonal exhaust port 666 was formed. By adopting such a configuration in addition to the small hole group 662 of the lower side wall portion 656, exhaust can be performed rearward or diagonally rearward of the display control device 45, so it is possible to suppress a decrease in heat radiation performance. it can.

  Furthermore, in the back wall portion 655, a fan duct portion 663 projecting rearward is formed corresponding to the cooling fan 675 described later. An air vent 664 is formed at the top of the fan duct portion 663. In the present embodiment, the air vent 664 functions as an air intake for introducing outside air for cooling.

  Further, in the display control substrate 650, predetermined gaps are secured between the mounting surface 650a on which various electronic components are mounted and the back wall portion 655 of the unit cover 654, and between the substrate back surface 650b and the base plate 645. It is mounted so that the

  On the display control board 650, various electronic components such as a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, and a VDP 526 which will be described later are mounted. Further, the display control board 650 is electrically connected to the liquid crystal display 647 (the decorative symbol display device 42) by a cable connector (not shown) through the terminal portion 657. Therefore, an output port 529 to be described later is configured by the terminal portion 657. Further, an input port 527 described later is configured by the terminal portions 658 and 659.

  Furthermore, in the present embodiment, on the display control substrate 650, a heat sink (heat dissipation plate) 670 for dissipating heat generated by the CPU 521 and the VDP 526, which are integrated circuits with a large amount of heat generation, is mounted.

  The heat sink 670 in the present embodiment is formed in a substantially flat plate shape by an aluminum alloy or the like having a good thermal conductivity. Among them, a region corresponding to the CPU 521 and the VDP 526 is a step-like contact portion 671 by bending, and the back surface of the contact portion 671 is in surface contact with the CPU 521 and the VDP 526. Therefore, the heat generated by the CPU 521 and the VDP 526 is conducted to the heat sink 670 side and dissipated from the heat sink 670. As a result, the CPU 521 and the VDP 526 are cooled. In the heat sink 670 according to the present embodiment, since a large number of heat dissipating fins and the like are omitted, the display control device 45 can be formed relatively thin.

  A non-conductive silicon rubber plate 673 with good heat transfer performance is attached to the upper surface of the CPU 521 and the VDP 526 (see FIG. 14). That is, the CPU 521 and the VDP 526 and the contact portion 671 of the heat sink 670 are in contact via the silicon rubber plate 673. The silicon rubber plate 673 is a thin rubber plate containing a component with high thermal conductivity and having elasticity. Thus, the CPU 521 and the VDP 526 are in close contact with the contact portion 671 of the heat sink 670 without a gap. Of course, the invention is not limited to this, and contact may be made via a nonconductive heat conductive buffer such as silicon grease or a heat conductive tape.

  Furthermore, a cooling fan 675 serving as a blower is attached to the heat sink 670 at a position rearward of the contact portion 671 so as to face the VDP 526 via the contact portion 671. The cooling fan 675 is inserted into the above-described fan duct portion 663 when the unit cover 654 is assembled. Therefore, the VDP 526 corresponds to a specific electronic component in the present embodiment.

  The cooling fan 675 is a thin axial flow type, and a housing 680 contains a fan 681 composed of a plurality of blades and a motor 682 for driving the fan 681. Driving power is supplied to the cooling fan 675 through the display control substrate 650.

  With the above configuration, when the cooling fan 675 is driven, the outside air sucked through the fan duct portion 663 is introduced into the unit cover 654 (the display control device 45) and sprayed to the heat sink 670. Then, after the heat is exchanged with the heat sink 670, the outside air passes through the inside of the unit cover 654, and is outside the small hole group 662 of the upper and lower side wall portions 656 and the oblique exhaust port 666 of the inclined wall portion 665. Discharged into Thus, the CPU 521 and the VDP 526 are cooled.

  The decorative symbol display device 42 and the display control device 45 configured as described above are integrated (unitized) by assembling the window frame 649 and the unit cover 654. More specifically, a plurality of locking claws 649a are formed in the window frame 649, and correspondingly, locking holes 683 in which the locking claws 649a are locked are formed in the unit cover 654. Then, the window frame 649 and the unit cover 654 are engaged to form a substantially box-like housing, in which the decorative symbol display device 42 and the display control device 45 are accommodated and integrated. .

  Further, sealing members 686 are fitted in the two locking holes 683 at the upper right and lower left of the rear surface, respectively. The sealing member 686 is not removable once fitted, and restricts the elastic deformation of the locking claw 649a. As a result, the window frame 649 and the unit cover 654 are unopenably connected. However, the window frame 649 and the unit cover 654 can be opened by cutting or removing the sealing member 686, for example. Therefore, the sealing process by the sealing member 686 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if unauthorized opening is performed.

  Now, in the present embodiment, as shown in FIGS. 10 to 13, the sub control device 560 is mounted on the back wall portion 655 of the unit cover 654.

This suppresses expansion of the installation space in the depth direction of the main controller 261 and the display control device 45 etc., and efficiently and compactly arranges the main control device 261 and the display control device 45 etc. This is to ensure the space on the back side of the substrate mounting portion 201b as wide as possible. By securing a relatively large space on the back side of the board mounting portion 201b, for example, it becomes easy to cope with the case where a larger product is placed on the game board 30, etc., and versatility is enhanced when changing the model or the like. In the present embodiment, since the fan duct portion 663 protrudes rearward with respect to the back wall portion 655 of the unit cover 654, the configuration is such, but if the fan duct portion 663 is not protruding Preferably, the back and forth direction positions of the back wall 267 of the main control device 261 and the back wall 655 of the display control device 45 are substantially the same.

  Further, as shown in FIG. 7, the box base 265 and the box cover 266 are connected by the left and right sealing units 264A and 264B, and when the substrate box 263 is unsealed, predetermined operation is performed in the sealing units 264A and 264B. It is configured to leave a trace of Thus, it can be easily found that the substrate box 263 has been tampered with. The sealing unit in the present embodiment is configured by the sealing units 264A and 264B.

  The sealing unit 264A, 264B may have any configuration as long as it connects the box base 265 and the box cover 266 in an unopenable manner, but in the present embodiment, the left sealing unit 264A has three sealing members connected. The right sealing unit 264B has a configuration in which two sealing members are connected. The box base 265 and the box cover 266 are connected unopenably by inserting the locking claws into the long holes of these sealing members. The sealing process by the sealing units 264A and 264B prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if unauthorized opening is performed, Even once opened, it is possible to perform the opening and sealing process again. That is, the sealing process is performed by inserting the locking claw into the elongated hole of at least one sealing member among the five sealing members constituting the sealing units 264A and 264B. Then, when the substrate box 263 is opened due to a defect or the like of the stored main substrate 262, the connection between the sealing member in which the locking claw is inserted and the other sealing member is cut. Thereafter, when the sealing process is performed again, the locking claw is inserted into the long hole of the other sealing member. If a history indicating that the substrate box 263 has been opened is left in the substrate box 263, by looking at the substrate box 263, it is possible to easily find that unauthorized opening has been performed.

  Further, as shown in FIGS. 7 and 15, in the vicinity of the upper edge portion of the main substrate 262, a plurality of terminal portions 701, 702, 703, 704, 705 for connecting connectors of various cable connectors in the left-right direction It is installed side by side. Each of the terminal portions 701 to 705 is formed so as to protrude from the main substrate 262, and is exposed outside the substrate box 263 through a hole 266b opened in a recess (retracting portion) 266a formed on the upper portion of the box cover 266. It has become. The configurations of the terminal portions 701 to 705 and the cable connectors connected to these are similar and general, and thus for convenience, the illustration of each cable connector is omitted in FIG. 7 and in FIG. Shows only the terminal portion 703 and the cable connector CC connected thereto as an example.

  The other of the cable connectors, one of which is connected to the sub controller 560, is connected to the terminal portion 701. In the present embodiment, the main substrate 262 is electrically connected to the normal symbol display device 41 and the special display device 43 through the cable connector, ie, the sub controller 560.

  Further, a connector of a cable connector connected to the payout control device 311 is connected to the terminal portion 702. The terminal portion 703 is connected to a connector CN of a cable connector CC connected to a first board relay board 226 which has a relay function with the winning opening switch 221 and the like. To the terminal portion 704, a connector of a cable connector connected to the first trigger corresponding port switch 224 is connected. The terminal unit 705 is connected to a connector of a cable connector connected to a second board relay board 227 which performs a relay function with the special winning opening solenoid, the first trigger corresponding opening solenoid, and the like.

  As described above, since the terminal portions 701 to 705 project toward the back side of the pachinko machine 10, the mounting direction of the connector CN or the like of the cable connector CC is the front side direction of the pachinko machine 10 (left direction in FIG. 15). The removal direction of the connector CN or the like is the back side direction of the pachinko machine 10 (right direction in FIG. 15).

  Then, in the closed state of the back pack 351 (back pack unit 203) described later, the protection direction described later is covered by covering at least the removal direction side of the connector CN etc. of the cable connector CC connected to the respective terminal portions 701 to 705. A cover 354 is disposed. As shown in FIG. 15, the distance between the protective cover portion 354 and the connector CN or the like in the closed state of the back pack 351 is shorter than the distance (insertion amount) necessary for removing the connector CN or the like. Therefore, unless the back pack 351 is opened, the connection of the connector CN or the like of the cable connector CC can not be released. That is, even if it is attempted to attach a so-called hanging board or replace the main board 262 with a fraudulent product after illegally removing the connector CN or the like, the protective cover portion 354 interferes with the connector Such action can be deterred because removal of CN etc. is practically impossible. Moreover, in the present embodiment, since the back pack unit 203 is configured to be locked, the effect is more reliable.

  Of the various cable connectors, the connector CN of the cable connector CC of the first board relay board 226, the cable connector of the first trigger corresponding port switch 224, and the cable connector of the second board relay board 227 The back side of the main control device 261 is passed through the gap between the main control device 261 and the display control device 45 from the back side.

  More specifically, the cable connector CC or the like is designed to pass through the formation section of the inclined wall portion 665 of the unit cover 654 of the display control device 45.

  This prevents the cable CA or the like of the cable connector CC from being excessively bent due to the display control device 45 and the main control device 261 being disposed adjacent to each other and the gap between the two being narrowed. It is a device to do. That is, in the lower rear corner portion adjacent to the main control device 261 in the display control device 45 (unit cover 654), the inclined wall portion 665 is formed by chamfering the corner portion. A space, i.e., a relief that allows bending of the cable CA or the like of the cable connector CC is formed. As a result, even when the display control device 45 and the main control device 261 are arranged adjacent to each other, the cable CA of the cable connector CC can be bent with extra space without excessive bending, and wiring can be performed. It can be reduced.

  Also, since the length of the cable CA etc. of the cable connector CC is usually set longer in consideration of the connection work with the respective terminal portions 701 to 705, the display control of the surplus portion such as the cable CA etc. is temporarily performed. If it bends not to the device 45 side but to the main control device 261 side, the surplus portion such as the cable CA may hang down and may protrude from the lower end of the protective cover portion 354. In such a state, there is a risk that fraudulent acts such as “hanging” as described above may be performed, and visual recognition of the inside of the main control device 261 is impeded, and early detection of fraudulent acts or the like may be delayed. There is also. In this respect, according to the present embodiment, since the inclined wall 665 is formed on the display control device 45 side, bending to the display control device 45 side is promoted, and thus such a problem hardly occurs. .

  The second control board unit 202 includes a payout control device 311, a emission control device 312, a power supply device 313, and a card unit connection substrate 314. The payout control device 311, the launch control device 312, and the power supply device 313, as is well known, have a control board including a CPU, ROM, RAM, various ports, etc., which are central to control.

  The payout control device 311, the emission control device 312, and the power supply device 313 are also accommodated and configured in the corresponding substrate boxes 315, 316, and 317, respectively. However, the emission control device 312 (substrate box 316) is disposed on the back side of the power supply device 313 (substrate box 317). In addition, a sealing unit is provided in the substrate box 315 in which the payout control device 311 is accommodated, as in the case of the main control device 261 described above, and an opened trace of the substrate box 315 remains.

  The payout control device 311 is provided with a state recovery switch 321. For example, when the state recovery switch 321 is pressed at the occurrence of a dispensing error such as a ball clogging of the dispensing motor unit, the dispensing motor is rotated forward and reverse to resolve the ball clogging (return to a normal state).

  In addition, the power supply device 313 is provided with a RAM erase switch 323. The pachinko machine 10 has a backup function, and maintains the state at the time of the power failure even when the power failure occurs, and may restore the state at the time of the power failure when recovering from the power failure (power recovery) it can. Therefore, when the power is turned off in the normal procedure (for example, at the end of business in the game arcade), the state before the power is shut off is stored and held, so when returning to the initial state when the power is turned on Throw in

  Next, the configuration of the back pack unit 203 will be described. The back pack unit 203 is an integrated unit of a resin molded back pack 351 and a game ball dispensing mechanism portion 352.

A cover 354 is disposed. The distance between the protective cover portion 354 and the connector CN or the like in the closed state of the back pack 351 is shorter than the distance (the amount of insertion) necessary for removing the connector CN or the like. Therefore, unless the back pack 351 is opened, the connection of the connector CN or the like of the cable connector CC can not be released. That is, even if it is attempted to attach a so-called hanging board or replace the main board 262 with a fraudulent product after illegally removing the connector CN or the like, the protective cover portion 354 interferes with the connector Such action can be deterred because removal of CN etc. is practically impossible. Moreover, in the present embodiment, since the back pack unit 203 is configured to be locked, the effect is more reliable.

In addition, the present invention may be applied to the relationship of other control devices such as the relationship between the main control device 261 and the payout control device 311. Of course, not only the one-to-one relationship but also one-to-multiple relationships can be applied. For example, in addition to the display control device 45 being disposed adjacent to the upper side of the main control device 261, the payout control device 311 is disposed adjacent to the lower side, and the inclined wall portion in the payout control device 311 An inclined wall portion and an oblique exhaust port similar to the 665 and the oblique exhaust port 666 may be formed.

  Of course, the present invention may be applied to a configuration in which control devices not provided with a cooling fan are arranged adjacent to each other. In this case, the oblique exhaust port may be omitted from the inclined wall portion (see FIG. 17).

  (B) In the embodiment described above, the cooling fan 675 is disposed to face the VDP 526 and configured to blow air toward the VDP 526. Not limited to this, the cooling fan 675 may be disposed so as to blow air toward at least the inside of the display control device 45. For example, it may be disposed to face the mounting surface of the display control board 650 at a position deviated from the VDP 526. Therefore, as long as it is disposed in this manner, it may be disposed opposite to other electronic components such as the CPU 521.

  (C) In the above embodiment, the fan duct portion 663 is formed to protrude from the back wall portion 655 of the unit cover 654, and a plurality of air vents 664 as air inlets are formed at the top thereof. For example, the fan duct 663 may be omitted, and the back wall 655 of the unit cover 654 may be substantially flat. In this manner, the display control device 45 and the main control device 261 can be more compactly arranged in the front-rear direction than the above embodiment.

  In addition, an air inlet having a size equal to that of the cooling fan 675 may be provided so that the entire cooling fan 675 faces the outside. In this way, the intake performance can be improved. However, in order to improve the safety, it is preferable to provide a plurality of small vents 664 as in the above embodiment so that a finger or the like can not be inserted into the cooling fan 675.

  (D) In the above embodiment, the display control device 45 and the main control device 261 are arranged in the proximity state, but the present invention is not limited to this, and both may be arranged in the contact state. In this case, for example, as shown in FIG. 16, the small hole group 662 may be omitted in the lower side wall portion 656. In this way, since the hot air is not blown to the lower main control device 261, the influence on the main control device 261 can be reduced. In addition, since it is not necessary to secure a ventilation space between the display control device 45 and the main control device 261, it is also possible to closely contact both the control devices 45 and 261, and to effectively use a limited installation space. Can. In this case, a recess may be formed in at least one of the control devices 45 and 261 for passing the cable connector CC or the like.

  (E) The inclined wall portion 665 of the display control device 45 may be provided with a guide portion for guiding the cable CA or the like of the cable connector CC to the side of the inclined wall portion 665. For example, as shown in FIG. 17, in the inclined wall portion 665 where the oblique exhaust port 666 is omitted, a hooking portion 900 for hooking the cable CA or the like may be provided. Thus, the cable CA etc. can be guided in the direction of the inclined wall 665 side, that is, in the opposite direction to the main control device 261, and it can promote that the cable CA etc. becomes curved. The bending suppression effect is more reliably exerted.

  (F) A pachinko machine of a type different from that of the above embodiment may be implemented. In addition to pachinko machines, various types of game machines such as arrange ball machines, ball ball similar to that, drum-type game machines such as slot machines, game machines of a type combining slot machines and pachinko machines, etc. It is also good.
