Description

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

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

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

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

  As described above, in recent years, due to diversification of presentation functions, higher performance electronic components such as a CPU having a high processing speed have been mounted on the control board. For example, a display control board that controls a liquid crystal display device and the like is equipped with a CPU, an image processing device (VDP), and the like that have a high processing speed, thereby enabling various display effects.

  In general, when the processing speed of the CPU or the like, that is, the operation clock frequency is increased, the power consumption is increased and the amount of generated heat is also increased. If a large amount of heat is generated in the resin case in this way, the heat dissipation hole alone cannot sufficiently release the heat, and the control device may malfunction due to the heat generated by the electronic component. . Therefore, in recent control devices equipped with high-performance electronic components, a more efficient heat dissipation measure is required, such as mounting a blowing means such as a cooling fan (see Patent Document 1, for example).

  However, since a lot of equipment such as a control device is installed in a limited installation space on the back side of the gaming machine, it is close to (or appropriate to) a predetermined control device (board box) provided with the air blowing means. Other control devices may be arranged. In this case, if the installation distance between the two is too small, a sufficient ventilation space cannot be secured, and there is a concern that exhaust cannot be efficiently performed from the exhaust port opened in the adjacent side wall surface of the control device provided with the blowing means. Is done.

  In view of such problems, when the control devices are arranged close to each other, it may be possible to secure the ventilation space by shifting both control devices back and forth, but the space of the island facilities of the game hall where the gaming machine is installed Therefore, there is a limit to extending the installation space of the control device in the depth direction. In other words, when many devices such as a control device are installed on the back side of the gaming machine, it is desired to arrange these various devices more compactly not only in the vertical and horizontal directions but also in the longitudinal direction. In addition, in order to increase the size of the control board or to ensure expandability for adding new equipment, when multiple control devices are installed side by side, their position in the front-rear direction is as much as possible. Are preferably arranged efficiently without waste so that the mechanism on the back side of the gaming machine does not expand in the depth direction.

  Note that the above problem is not limited to the back side of the gaming machine and the like, 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 pachinko machine, but also applies to other gaming machines such as a slot machine.

  The present invention has been made to solve the above-described problems, and its object is to secure a larger installation space for the control device and the like, without impairing the heat dissipation performance of the control device, and to effectively use the installation space. An object of the present invention is to provide a gaming machine that can handle such a situation.

  Hereinafter, each means suitable for solving the above-described problems will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A gaming machine that performs a lottery based on a predetermined opportunity and generates a special gaming state advantageous to a player when a winning result is obtained by the lottery,
A first board box containing a first control board (for example, a sub-control board) and a second board box containing a second control board (for example, a main control board);
The first board box and the second board box are opposed to the front wall portion disposed opposite to the mounting surface of each control board on which various electronic components are mounted, and opposite to the back surface of each control board. And a rear wall portion arranged in a substantially box shape with a peripheral wall portion arranged opposite to the peripheral edge portion of each control board, so that the mounting surfaces of both control boards face the same direction. In a gaming machine that is arranged side by side in the up-down or left-right direction, and a part of the peripheral wall portion is arranged adjacent to each other so that the arrangement positions in the front-rear direction overlap each other,
While provided with a blowing means for blowing air toward the inside of the first substrate box,
In the first substrate box, at least at a predetermined position on the side adjacent to the second substrate box, an inclined wall portion that is inclined with respect to the first control substrate is provided at a connecting portion of the peripheral wall portion and the front wall portion. And the game machine characterized by providing the exhaust port in the said inclination wall part.

  According to the above means 1, by providing the air blowing means for blowing air toward the inside of the first substrate box, for example, a predetermined electronic component such as an electronic component that emits high heat, such as a CPU, rather than the air in the first substrate box. The cold outside air is intensively blown, and the electronic component can be efficiently cooled.

  Furthermore, in the first substrate box provided with the air blowing means, by providing the inclined wall portion and the exhaust port opened there in a location adjacent to the second substrate box, the adjacent second substrate box is not obstructed. The air permeability can be sufficiently secured. As a result, exhaust can be performed efficiently, and a decrease in heat dissipation performance can be suppressed.

  In addition, the exhaust port can be omitted from the side wall portion adjacent to the second substrate box. In this way, since hot air is not blown against the adjacent second substrate box, the influence on the adjacent second substrate box (second control substrate) can be reduced. As a result, since it is not necessary to secure a ventilation space between the adjacent first and second board boxes, both board boxes can be brought into close contact with each other. As a result, it is possible to expand both the board boxes until they abut against each other, it is possible to cope with an increase in the size of the control board, and to effectively use a limited installation space.

  As a result, it is easy to secure a larger space for installing both board boxes without impairing the heat dissipation performance of the first board box.

  Of course, since it is not necessary to dispose both board boxes in the front-rear direction, the installation space in the front-rear direction can be effectively used. That is, it is possible to suppress the expansion of the installation space of the substrate box or the like in the depth direction, to efficiently arrange the substrate box or the like more efficiently without waste. As a result, it is possible to cope with a case where an installation space for an island facility or the like of a game hall in which a gaming machine is installed is relatively narrow while securing expandability for adding new equipment.

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

  In addition, the fact that both of the board boxes are “a part of the peripheral wall portions are arranged adjacent to each other” means that the peripheral wall portions of the two board boxes are arranged close to each other and are in contact with each other. Cases are also included.

  Mean 2. 2. The gaming machine according to claim 1, wherein the first board box and the second board box are arranged such that front and rear direction positions of the front wall portions are the same or substantially the same position.

  According to the said means 2, both board | substrate boxes can be arrange | positioned more compactly, ensuring the exhaust performance (heat dissipation performance) from the exhaust port of an inclined wall part. As a result, the effect of the means 1 can be further enhanced. If the front and rear widths of both board boxes are different, or if the position of the front wall of both board boxes does not match due to structural reasons such as the arrangement configuration, a spacer or the like is placed on the back side of one board box. Therefore, the position of both front wall parts will be matched. At this time, in some cases, a relatively wide space may be secured on the back side of one of the substrate boxes. In this case, for example, it becomes easy to deal with a case where a new device is added, and the versatility is increased when changing the model of the gaming machine. In other words, by aligning the positions of the front wall parts of both board boxes, both board boxes can be arranged more compactly, and the space on the back side of one board box is effective while suppressing the expansion of the installation space in the depth direction. Can be used for

Means 3. The air blowing means is disposed opposite to the mounting surface of the first control board, and
The game according to means 1 or 2, further comprising a cover body that is disposed to face the front wall portions of the first board box and the second board box and covers at least a range in which the air blowing means is provided. Machine.

  According to the means 3, the outside air can be efficiently applied to the electronic component mounted on the first control board. Further, by providing a cover body disposed on the front wall portion of both board boxes, that is, on the suction side of the blower means so as to face the blower means, foreign substances such as dust and dust can enter the first board box. Can be suppressed. As a result, it is possible to achieve both suppression of entry of foreign matter such as dust and dust and improvement of cooling efficiency of electronic components.

  Means 4. 4. The means 3 according to claim 3, wherein the blower means is disposed opposite to a specific electronic component among the electronic components mounted on the first control board, and blows air toward the specific electronic component. Gaming machine.

  According to the means 4, the specific electronic component can be intensively cooled, so that the specific electronic component can be efficiently maintained at an appropriate temperature.

  Means 5. The gaming machine according to claim 3 or 4, wherein the cover body covers an area where the inclined wall portion is provided and has an exhaust hole corresponding to the exhaust port.

  According to the means 5, by providing the cover body with the exhaust holes, it is possible to suppress a decrease in exhaust performance (heat radiation performance) from the exhaust port of the inclined wall portion.

Means 6. The second control board is provided with a terminal portion on the mounting surface for transmitting or receiving a signal to / from an electrical component outside the second control board, and the terminal portion is exposed. Housed in the second substrate box,
A cable connector electrically connected to the electrical component is drawn from the back side of the two board boxes through the gap between the two board boxes to the front side of the two board boxes, and the connector of the cable connector is the first connector. 2 connected to the terminal part of the control board,
The cover body is configured to cover the side of the connector of the cable connector connected to the terminal portion in the direction of removal, at least at a position facing the terminal portion of the second control board,
The gaming machine according to any one of means 3 to 5, wherein an escape portion that allows the cable of the cable connector to be bent is formed by providing the inclined wall portion in the first board box.

  In recent years, for example, malicious acts such as an action called “hanging” in which a separate board is attached to a cable connector or a terminal portion have become a problem. In this regard, according to the means 6, the terminal portion and the connector of the cable connector connected to the terminal portion are covered with the cover body. Therefore, even if a malicious action such as mounting a so-called hanging board or replacing the control board with an unauthorized product is performed after the connector is illegally removed, the cover body is not removed unless the cover body is removed. Since it is difficult to remove the connector due to obstruction, such an action can be suppressed.

  Furthermore, it is conceivable that the cover body is arranged as close as possible to the board box to make it difficult to remove the connector connected to the terminal portion.

  However, as described above, when the cover body is arranged close to the board box, the gap between the two becomes narrow, and for example, if the cable is not bent excessively at the corner of the board box, the cable connector is wired. There is a risk that it will not be possible. In general, the cable length of the cable connector is set with a certain margin in consideration of the connection work with the terminal part of the control board, etc., so that the cable surplus portion is covered with excessive bending. There is also a risk of being housed between the body and the substrate box. As a result, there is a concern about an adverse effect on the cable connector.

  In particular, when a large number of devices such as board boxes are installed in a limited installation space and the board boxes are arranged close to each other, or the cable of the cable connector is composed of multiple wires, a relatively thick one, etc. When using the above, the above-mentioned problem tends to appear more remarkably. If the position of the external electrical component or the terminal portion thereof and the position of the terminal portion of the control board connected to the electrical component or the like via the cable connector are different in the left-right direction, the cable connector Since the bending in the left-right direction is also added, the cable connector is more likely to bend more easily, and the above-described problems are more likely to appear.

  In this regard, as in this means, by having an inclined wall portion that chamfers the corner portion of the first substrate box on the side adjacent to the second substrate box, a space that allows the cable to be bent, that is, a relief portion, is provided. It is formed. As a result, even when the first board box and the second board box are arranged adjacent to each other, the cable connector can be bent with sufficient margins without being bent excessively, so that adverse effects on the cable connector can also be reduced. As a result, the cover body can be disposed closer to both the board boxes, so that it is possible to further improve the fraud prevention effect.

  The “electrical component outside the second control board” includes, for example, the “first control board”, “a ball entry means provided in the game area and causing a special game state advantageous to the player”. Corresponding pitch detection means provided "," Drive means provided corresponding to a variable winning device that is provided in the game area and is activated when a special gaming state advantageous to the player is generated ", various electric Examples include a “relay board” that relays components.

  Mean 7 The gaming machine according to claim 6, 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 means 7, unless the cover body is removed, the connection of the connector of the cable connector cannot be released, and the illegal act suppressing effect of the means 6 is more reliably exhibited.

  Means 8. The gaming machine according to claim 6 or 7, further comprising a guide portion for guiding the cable toward the inclined wall portion.

  According to the means 8, by providing the guide portion, the cable can be guided to the side of the inclined wall portion, that is, the direction opposite to the second substrate box, and the cable can be promoted to be bent. The bending suppressing effect of the means 6 is more reliably exhibited.

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

  Since the main control board of the means 9 is the control board that has the greatest influence on the control of the gaming machine, the effect of avoiding exhaust heat from other board boxes as described above and the effect of suppressing fraud are more effective. It will be.

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

  According to the means 10, in the unlikely event that the second substrate box is opened, some trace remains in the sealing means, and it is possible to easily find an illegal act by checking it. For this reason, it is possible not only to directly prevent fraud but also to prevent fraud from the aspect of being able to detect fraud early.

The connector of the cable connector and the like can be inserted and removed from the outside of the display control device 45 to the terminal portions 658 and 659 of the display control board 650 through the terminal portion window 660.

  A small hole group 662 for ventilation is formed in each of the upper, lower, left and right side wall portions 656 of the unit cover 654. In the present embodiment, these small hole groups 662 function as exhaust ports. As can be seen from FIG. 11 and the like, the small holes constituting the small hole group 662 include two types of small circular small holes 662a and larger long holes 662b. This is from the viewpoint of preventing the occurrence of a failure or the like and preventing fraud. When an electronic component that is not desired to come into contact with a foreign object or the like is disposed in the vicinity of the side wall portion 656, a circular small hole 662a corresponding to the location. Is provided. Further, 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, the small hole group 662 may not be formed.

  As can be seen from FIGS. 5 to 7, many devices are installed in the pachinko machine 10 in a limited installation space on the back side. For this reason, various devices are arranged 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 this embodiment, since the installation interval between the two is relatively narrow, a sufficient ventilation space cannot be secured, and the small hole group 662 in the side wall portion 656 on the lower side of the unit cover 654 (see FIG. 12). Therefore, there is a concern that the exhaust cannot be performed efficiently.

  The display control board 650 has predetermined gaps 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 board back surface 650b and the base plate 645. (See FIG. 14).

  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 on the display control board 650. Further, the display control board 650 is electrically connected to the liquid crystal display 647 (decorative symbol display device 42) through a terminal portion 657 through a cable connector (not shown). Therefore, an output port 529, which will be described later, is configured by the terminal portion 657. The terminal portions 658 and 659 constitute an input port 527 described later.

  Further, in the present embodiment, a heat sink (heat radiating plate) 670 for radiating heat generated by the CPU 521 and the VDP 526 which are integrated circuits with a large amount of heat is placed on the display control board 650.

  The heat sink 670 in the present embodiment is formed in a substantially flat plate shape from an aluminum alloy having a good thermal conductivity. Among these, a region corresponding to the CPU 521 and the VDP 526 is a stepped 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. Accordingly, the heat generated by the CPU 521 and the VDP 526 is conducted to the heat sink 670 side and is radiated from the heat sink 670. As a result, the CPU 521 and the VDP 526 are cooled. In the heat sink 670 in the present embodiment, since a large number of heat radiation fins are omitted, the display control device 45 portion can be formed relatively thin.

  A silicon rubber plate 673 that is non-conductive and has good heat transfer performance is attached to the upper surfaces of the CPU 521 and the VDP 526 (see FIG. 14). That is, the CPU 521 and the VDP 526 are in contact with the contact portion 671 of the heat sink 670 via the silicon rubber plate 673. The silicon rubber plate 673 is a thin rubber plate that includes a component having high thermal conductivity and has elasticity. As a result, 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 contact is not limited to this, and the contact may be made through a non-conductive heat transfer buffer such as silicon grease or heat transfer tape.

  Furthermore, a cooling fan 675 as a blowing unit is attached to the heat sink 670 at a position behind the contact portion 671 so as to face the VDP 526 via the contact portion 671. The cooling fan 675 is inserted into the fan duct portion 663 described above when the unit cover 654 is assembled. Accordingly, 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 fan 681 composed of a plurality of blades and a motor 682 for driving the fan 681 are accommodated in a housing 680. Driving power is supplied to the cooling fan 675 via the display control board 650.

  With the above configuration, when the cooling fan 675 is driven, outside air sucked through the fan duct portion 663 is introduced into the unit cover 654 (display control device 45) and blown onto the heat sink 670. Then, after the heat exchange with the heat sink 670 is performed, the outside air passes through the unit cover 654 and is externally provided from the small hole group 662 of the upper and lower side walls 656 and the oblique exhaust port 666 of the inclined wall 665. To be discharged. As a result, the CPU 521 and the VDP 526 are cooled.

More specifically, the window frame frame 649 is formed with a plurality of locking claws 649a, and the unit cover 654 is formed with a locking hole 683 for locking the locking claws 649a. The window frame 649 and the unit cover 654 are locked to form a substantially box-shaped 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 into the two locking holes 683 on the upper right and lower left of the back surface. Once the sealing member 686 is fitted, it cannot be removed and restricts elastic deformation of the locking claw 649a. As a result, the window frame 649 and the unit cover 654 are connected so as not to be opened. However, the window frame 649 and the unit cover 654 can be opened by removing the sealing member 686 by cutting or the like. 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 the unauthorized opening is performed.

  As shown in FIGS. 7 and 15, a plurality of terminal portions 701, 702, 703, 704, and 705 for connecting connectors of various cable connectors are arranged in the left-right direction in the vicinity of the upper edge portion of the main board 262. Along the line. Each of the terminal portions 701 to 705 protrudes from the main substrate 262 and is exposed to the outside of the substrate box 263 through a hole 266b opened in a recess (retractable portion) 266a formed in the upper portion of the box cover 266. It has become. Since the configurations of the terminal portions 701 to 705 and the cable connectors connected thereto are the same and general, for convenience, the illustration of each cable connector is omitted in FIG. Shows only the terminal portion 703 and the cable connector CC connected thereto as an example.

  The other connector of the cable connector that is connected to the sub-control device 560 is connected to the terminal portion 701. In the present embodiment, the main board 262 is electrically connected to the normal symbol display device 41 and the special display device 43 via this cable connector, that is, the sub-control device 560.

  In addition, a connector of a cable connector connected to the payout control device 311 is connected to the terminal portion 702. Connected to the terminal portion 703 is a connector CN of a cable connector CC connected to the first board surface relay board 226 that performs a relay function with the prize opening switch 221 and the like. A connector of a cable connector connected to the first opportunity corresponding port switch 224 is connected to the terminal portion 704. The terminal portion 705 is connected to a connector of a cable connector connected to the second board surface relay board 227 that performs a relay function with a prize winning port solenoid, a first opportunity corresponding port solenoid or the like.

  As described above, since the terminal portions 701 to 705 protrude toward the back side of the pachinko machine 10, the attachment direction of the connector CN of the cable connector CC is the front side direction of the pachinko machine 10 (left direction in FIG. 15). Thus, the removal direction of the connector CN and the like is the rear side direction of the pachinko machine 10 (right direction in FIG. 15).

  In the closed state of the back pack 351 (back pack unit 203), which will be described later, at least the cable CN connected to each of the terminal portions 701 to 705 is covered so as to cover the direction in which the connector CN and the like are pulled out. A cover portion 354 is disposed. As shown in FIG. 15, the distance between the protective cover 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 and the like of the cable connector CC cannot be released. In other words, even if the connector CN or the like is illegally removed and a malicious action such as mounting a so-called hanging board or replacing the main board 262 with an illegal product is performed, the protective cover 354 obstructs the connector. Since removal of CN or the like is virtually impossible, such an action can be suppressed. In addition, in the present embodiment, since the back pack unit 203 is locked, the effect is more certain.

  Of the various cable connectors, the connector CN of the cable connector CC of the first board surface relay board 226, the cable connector of the first opportunity corresponding port switch 224, and the cable connector of the second board surface relay board 227 are the same as those of the game board 30. From the back side, it passes through the gap between the main control unit 261 and the display control unit 45 to the back side of the main control unit 261.

  More specifically, the cable connector CC and the like are designed to pass through a section where the inclined wall portion 665 of the unit cover 654 of the display control device 45 is formed.

  This suppresses excessive bending of the cable CA or the like of the cable connector CC due to the display controller 45 and the main controller 261 being arranged adjacent to each other and the gap between them being narrowed. It is a device to do. That is, in the display control device 45 (unit cover 654), an inclined wall portion 665 having a chamfered corner portion is formed at the lower rear corner portion adjacent to the main control device 261. Thus, a space allowing the bending of the cable CA or the like of the cable connector CC, that is, a relief portion 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 can be bent with sufficient margin without excessively bending the cable CA or the like. Can be reduced.

  In addition, since the length of the cable CA of the cable connector CC is normally set in consideration of the connection work with the terminal portions 701 to 705 and the like, the surplus portion of the cable CA or the like is temporarily controlled. If it bends to the main controller 261 side instead of the device 45 side, an excessive portion such as the cable CA may hang down and protrude from the lower end of the protective cover portion 354. In such a state, there is a possibility that an illegal act such as “hanging” as described above may be performed, and that the visual recognition of the inside of the main control device 261 may be hindered, and early detection of an illegal activity or the like may be delayed. There is also. In this regard, according to the present embodiment, since the inclined wall portion 665 is formed on the display control device 45 side, bending toward the display control device 45 side is promoted, and thus such a problem is unlikely to occur. .

However, the launch control device 312 (substrate box 316) is disposed behind the power supply device 313 (substrate box 317). Further, the substrate box 315 in which the dispensing control device 311 is accommodated is provided with a sealing unit in the same manner as the main control device 261 described above, so that a trace of opening the substrate box 315 remains.

  The payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball clogged in the payout motor unit, the payout motor is rotated forward and reverse to eliminate the ball clogging (return to a normal state).

  The power supply device 313 is provided with a RAM erase switch 323. This pachinko machine 10 has a backup function, so that even if a power failure occurs, the pachinko machine 10 retains the state at the time of the power failure and can be restored to the state at the time of the power failure when returning 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 the game hall), the state before the power is turned off is stored, and when returning to the initial state when turning on the power, .

  Next, the configuration of the back pack unit 203 will be described. The back pack unit 203 is a unit in which a resin-formed back pack 351 and a game ball payout mechanism 352 are integrated.

  The back pack 351 is integrally formed of, for example, ABS resin, and has a protective cover portion 354 that protrudes rearward from the pachinko machine and has a substantially rectangular parallelepiped shape.

On the other hand, the vent hole 354a functioning as an exhaust hole is provided at the rear position of the inclined wall portion 665 and the oblique exhaust port 666 of the display control device 45 so as not to deteriorate the exhaust performance of the oblique exhaust port 666. Is provided. In addition, in order to suppress an illegal act of the cable connector CC to the connector CN or the like, the vent hole 354a is not provided at a rear position of the connector CN or the like.

  The payout mechanism 352 is disposed so as to bypass the protective cover 354. That is, a tank 355 opened upward is provided above the protective cover portion 354, and game balls supplied from island facilities of the game arcade are sequentially supplied to the tank 355. Below the tank 355, for example, a tank rail 356 that has two rows of ball passages in the horizontal direction and that is gently inclined toward the downstream side is connected. Further, a case rail 357 is formed vertically on the downstream side of the tank rail 356. It is connected. The payout device 358 is provided at the most downstream portion of the case rail 357, and a required number of game balls are paid out appropriately according to a predetermined electrical configuration such as a payout motor 358a. Then, the game balls paid out from the payout device 358 are supplied to the upper plate 19 and the like.

  The payout mechanism 352 is provided with a payout relay board 381 for relaying a payout command signal from the payout control device 311 to the payout device 358, and a power switch board 382 for taking in the main power from the outside.

On the condition that it is not done, the launching device 70 is driven, and the game ball is launched at an intensity corresponding to the operation amount of the handle 18.

  The display control device 45 executes the variable display of the decorative symbols on the decorative symbol display device 42 in accordance with an instruction from the sub-control device 560. The display control device 45 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, a video display processor (VDP) 526, an input port 527, an output port 529, and bus lines 530 and 531. And. An input / output port 554 of the sub control device 560 is connected to the input port 527. Further, the CPU 521, the program ROM 522, the work RAM 523, and the VDP 526 are connected to the input port 527. An output port 529 is connected to the VDP 526 via a bus line 531, and a decorative symbol display device 42 as a liquid crystal display device is connected to the output port 529.

  The CPU 521 of the display control device 45 receives the display command transmitted from the sub-control device 560 via the input port 527 and analyzes the received command or performs predetermined arithmetic processing based on the received command to control the VDP 526 ( Specifically, internal command generation for VDP 526 is performed. Thereby, display control in the decorative symbol display device 42 is performed.

Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of a power failure and execute a power failure process (NMI interrupt processing).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

  The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  As described above in detail, in the present embodiment, by providing the cooling fan 675 that blows air toward the inside of the display control device 45, outside air that is colder than the air in the display control device 45 is concentrated on the VDP 526 and the like. Air can be blown and the VDP 526 and the like can be efficiently cooled.

  Further, in the present embodiment, an inclined wall portion 665 is formed at a connection portion between the back wall portion 655 and the lower side wall portion 656 at the lower portion of the display control device 45, and the oblique exhaust port is formed in the inclined wall portion 665. 666 was formed. By adopting such a configuration, air permeability can be sufficiently ensured without being obstructed by the adjacent main controller 261. As a result, exhaust can be performed efficiently, and a decrease in heat dissipation performance can be suppressed.

  In other words, the display control device 45 and the main control device 261 can be expanded until they substantially come into contact with each other, and it is possible to cope with an increase in the size of the control board and to effectively use a limited installation space. be able to. Of course, it is not necessary to displace the display control device 45 and the main control device 261 in the front-rear direction, so that the installation space in the front-rear direction can be effectively used. That is, expansion of the installation space of the main controller 261 and the like in the depth direction can be suppressed, and the main controller 261 and the like can be arranged more efficiently and efficiently without waste. As a result, it is possible to cope with a case where an installation space for an island facility or the like of a game hall in which a gaming machine is installed is relatively narrow while securing expandability for adding new equipment.

  Furthermore, in this embodiment, by providing the protective cover portion 354, it is possible to suppress entry of foreign matter such as dust and dust into the display control device 45. As a result, it is possible to achieve both suppression of entry of foreign matters such as dust and dust and improvement of cooling efficiency of the VDP 526 and the like. On the other hand, a vent hole 354a that functions as an exhaust hole is provided at the rear position of the inclined wall portion 665 and the oblique exhaust port 666 of the display control device 45, thereby suppressing a decrease in exhaust performance from the oblique exhaust port 666. Can do.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, an example in which the configuration including the cooling fan 675 is applied to the display control device 45 and the present invention is applied to the adjacent relationship between the display control device 45 and the main control device 261 has been described. However, the present invention is not limited to this. For example, the main control device 261 has the same cooling fan as the cooling fan 675, and the main control device 261 is similar to the inclined wall portion 665 and the oblique exhaust port 666. It is good also as a structure which provided the inclined wall part and the diagonal exhaust port. Further, the present invention may be applied in relation to other control devices such as the relationship between the main control device 261 and the payout control device 311. Of course, the present invention can be applied not only to a one-to-one relationship but also to a one-to-multiple relationship. 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 control unit 311 includes the inclined wall portion. An inclined wall portion and an oblique exhaust port similar to those of 665 and the oblique exhaust port 666 may be formed.

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

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

  Moreover, it is good also as a structure provided with the inlet of the magnitude | size equivalent to the said cooling fan 675 so that the whole cooling fan 675 may face outside. In this way, it is possible to improve the intake performance. However, in order to improve safety, it is preferable that a plurality of small ventilation holes 664 are provided as in the above-described embodiment so that a finger or the like cannot be inserted into the cooling fan 675.

  (D) It is good also as a structure which abbreviate | omitted the protective cover part 354. FIG. However, in order to protect various devices such as the variable display device unit 35 from game balls and to suppress illegal acts such as “hanging”, it is preferable to include a protective cover 354.

  (E) In the above embodiment, the display control device 45 and the main control device 261 are arranged in the proximity state. However, the present invention is not limited to this, and a configuration may be adopted in which both are arranged in a contact state. In this case, for example, as illustrated in FIG. 16, the small hole group 662 may be omitted from the lower side wall portion 656. In this way, hot air is not blown against the lower main controller 261, so that the influence on the main controller 261 can be reduced. As a result, since it is not necessary to secure a ventilation space between the display control device 45 and the main control device 261, both the control devices 45 and 261 can be brought into close contact with each other, and effective use of a limited installation space is achieved. Can do. In this case, the cable connector CC and the like may be wired around the left or right side of the two control devices 45 and 261, or the cable connector CC and the like are passed through at least one of the two control devices 45 and 261. It is good also as a structure which formed the recessed part.

  (F) The inclined wall portion 665 of the display control device 45 includes a guide portion that guides the cable CA or the like of the cable connector CC toward the inclined wall portion 665, for example, a hook portion that hooks the cable CA or the like. Also good. Thus, the cable CA or the like can be guided to the side of the inclined wall portion 665, that is, the direction opposite to the main controller 261, and the cable CA or the like can be promoted to be bent. The bending suppression effect is more reliably achieved.

  (G) You may implement as a pachinko machine of a different type from the above-mentioned embodiment. In addition to pachinko machines, the game is implemented as an arrangement ball machine, various types of game machines such as sparrow balls, slotted machines such as slot machines, and a game machine that combines slot machines and pachinko machines.
