As described above, conventionally, on the back side of a gaming machine such as a pachinko machine, various control devices for performing various controls related to the game and a payout mechanism for paying out game balls are arranged vertically and horizontally. Has been done. As the control device, for example, a main control device that performs overall control of a game, a payout control device that controls a game ball payout device, a display control device that controls a display device for performing display effects, a speaker, a lamp, and the like. A voice lamp control device and the like for controlling are provided.

In recent years, various electronic components mounted on the control board have been increasing along with improvement in performance of electronic components such as a central processing unit (CPU) constituting a main control unit of the control device and an increase in the amount of control data. Therefore, the size of the control board, and eventually the resin case (board box) that houses the control board, tends to increase. For example, a liquid crystal display device or the like is adopted as a display device, and this liquid crystal display portion tends to be gradually increased in size for the purpose of increasing interest. The size is also increasing in proportion to the liquid crystal display unit. Therefore, the display device (display control device) occupies a large area on the rear side of the gaming machine, and other control devices must be installed so as to avoid the installation space of the display device. The current situation is that it is becoming difficult.

Further, on the back side of the gaming machine, a number of cable connectors are electrically wired to connect the control devices to each other, or various electric parts such as a ball detection device and a variable winning device, and the control device. .. And each control device is provided with the terminal part to which the connector of a cable connector is connected (for example, refer to patent documents 1).

However, in recent years, various malicious acts related to the control device and the like have become a problem. Particularly in recent years, malicious acts such as the act of so-called "hanging" in which a separate substrate is attached to a cable connector or a terminal portion have become prominent.

On the other hand, it may be possible to provide a cover body that covers the back side of the gaming machine to make it difficult to remove the connector connected to the terminal portion of the control device. However, in this case, the effect is weak unless the cover body is arranged as close as possible to the control device.

However, if the cover body is placed close to the control device, the gap between the two becomes narrower, and the cable connector can be wired unless the cable is excessively bent, for example, at the corners of the control device (board box). There is a risk of disappearing. Also, in general, the cable length of the cable connector is set with a certain allowance in consideration of the connection work with the terminal part of the control device, etc. Therefore, cover the cable with the excess cable part bent forcibly. There is also a risk of being housed between the body and the control device. As a result, there is concern that the cable connector may be adversely affected.

In particular, when many devices such as control devices are installed in a limited installation space and the control devices are placed close to each other, or when the cable of the cable connector is composed of multiple wires, relatively thick one, etc. When the above is used, the above problems are more likely to appear.

The above problem is not limited to the rear 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-mentioned pachinko machines, and is applicable to other gaming machines such as slot machines.

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

Hereinafter, each means suitable for solving the above-mentioned problems will be described by dividing them into items. In addition, the action and effect peculiar to the corresponding means will be additionally described as needed.

Means 1. A gaming machine that performs a lottery based on a predetermined trigger and generates a special gaming state that is advantageous to the player when a winning result is obtained by the lottery,
A first board box containing a first control board (main control board); and a second board box containing a second control board (sub-control board),
The first board box and the second board box face a back wall of each control board and a front wall portion arranged opposite to a mounting surface of each control board on which various electronic components are mounted. Having a back wall portion and a peripheral wall portion that is disposed opposite to the peripheral edge portion of each control board, and has a substantially box shape so that the mounting surfaces of both control boards face in the same direction. In a gaming machine that is arranged side by side vertically or horizontally, and in which a part of the peripheral wall portions are arranged adjacent to each other so that their mutual arrangement positions in the front-back direction overlap,
The first control board is provided with a terminal portion on the mounting surface for transmitting or receiving a signal to or from an electric component external to the first control board, and the terminal portion is exposed. Housed in the first substrate box,
A cable connector electrically connected to the electric component is pulled out to the front side of the both board boxes from the back side of the both board boxes through the gap between the both board boxes, and the connector of the cable connector is 1 is a structure connected to the terminal portion of the control board,
The first board box and the second board box are arranged so as to face at least a part of the front wall portions thereof, and are connected to the terminal portions at least at positions facing the terminal portions of the first control board. A cover body that covers the connector removal direction side of the cable connector
In the second substrate box, a chamfered portion that is inclined with respect to the peripheral wall portion and the front wall portion is formed in at least a part of the connecting portion between the peripheral wall portion and the front wall portion on the side adjacent to the first substrate box. By doing so, an escape portion that allows the bending of the cable of the cable connector is formed.

According to the above means 1, the terminal portion and the connector of the cable connector connected to the terminal portion are covered with the cover body. Therefore, even if you attempt to perform malicious acts such as illegally removing the connector and then mounting a so-called hanging board or replacing the control board with an unauthorized product, the cover body will not be removed unless you remove it. Since it is difficult to remove the connector due to the hindrance, such an action can be suppressed.

Further, in the above means, the corners of the second substrate box adjacent to the first substrate box are chamfered to provide a space for allowing the cable to bend, that is, a relief portion. 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 and wired with a margin without excessive bending, so that adverse effects on the cable connector can be reduced. As a result, it is possible to dispose the cover body closer to both board boxes, so that it is possible to further improve the fraud prevention effect. If the position of the external electric component or the position of its terminal portion and the position of the terminal portion of the control board connected to the electric component or the like via the cable connector are different in the left-right direction, the cable connector Since the cable connector is also bent in the left-right direction, the cable connector is more easily bent, and the above-mentioned problem is more likely to appear. Therefore, in such a structure, the above means is more effective.

As a result, it is possible to effectively use the installation space of the board box and the like and to suppress fraud.

The relationship between the first board box and the second board box can be applied not only to the one-to-one relationship but also to the one-to-many relationship. That is, it can be applied to a configuration in which the second board box is arranged on at least one side of the upper, lower, left, and right sides of the first board 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, both board boxes are arranged so as to be in contact with each other, in that "the parts of the peripheral wall portions are arranged adjacent to each other", the peripheral wall portions of the both board boxes are arranged close to each other. The case is also included.

Further, the "electrical parts outside the first control board" are, for example, the "second control board" and "ball entry means which is provided in the game area and causes a special game state advantageous to the player. Corresponding ball detecting means", "driving means provided corresponding to the variable winning device provided in the game area and operated when generating a special game state advantageous to the player", various types of electricity An example is a "relay board" that relays components.

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

According to the above-mentioned means 2, the connection of the connector of the cable connector cannot be released unless the cover body is removed, and the fraud prevention effect of the above-mentioned means 1 is more reliably exhibited.

Means 3. The gaming machine according to means 1 or 2, further comprising a guide portion that guides the cable toward the chamfered portion.

According to the above means 3, by providing the guide portion, it is possible to guide the cable in the side of the chamfered portion, that is, in the direction opposite to the first substrate box, and to promote the cable to be in a curved state, The bending suppression effect of the above-mentioned means 1 is more reliably exhibited.

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

In general, electronic components such as a CPU mounted on a control board generate heat, and therefore, in a conventional control device, heat generated from the electronic component such as providing a heat dissipation hole in a board box for housing the control board. Various heat dissipation measures have been taken to efficiently release heat.

Further, in recent years, due to diversification of production functions and the like, higher performance electronic components such as a CPU having a high processing speed have been mounted on the control board. For example, a CPU having a high processing speed, an image processing device (VDP), and the like are mounted on a display control board that controls a liquid crystal display device or the like, which enables more various display effects.

Generally, when the processing speed of the CPU or the like, that is, the operating clock frequency increases, the power consumption increases accordingly and the amount of heat generated also increases. When a large amount of heat is generated in the resin case in this way, the above-mentioned heat dissipation holes alone cannot sufficiently dissipate the heat, and the heat generated by the electronic components may cause the control device to malfunction. .. Therefore, in recent control devices equipped with high-performance electronic parts, more efficient heat dissipation measures, such as mounting a ventilation means such as a cooling fan, are required.

However, since many devices such as a control device are installed in the game machine in a limited installation space, it is close (or abutted) to a predetermined control device (board box) equipped with the above-mentioned blower means. Then, another control device may be arranged. In this case, if the installation interval between the two is too narrow, a sufficient ventilation space cannot be secured, and there is concern that efficient exhaust cannot be performed from the exhaust port opened on the adjacent side wall surface of the control device equipped with the blowing means. To be done.

In view of such a problem, when the control devices are arranged close to each other, it is conceivable to shift both control devices back and forth to secure a ventilation space, but the space of the island facility of the game hall where the gaming machine is installed Therefore, there is a limit to expanding the installation space of the control device in the depth direction. That is, when many devices such as a control device are installed on the rear 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 front-back direction. In addition, in order to increase the size of the control board and to ensure expandability for adding new equipment, when multiple control devices are installed in parallel, position them in the front-back direction as much as possible. It is preferable that they are aligned so as to be efficiently arranged without waste so that the mechanism on the back side of the gaming machine does not expand in the depth direction.

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

Furthermore, in the second substrate box provided with the air blower, by providing the chamfered portion and the exhaust port opened therein at a position adjacent to the first substrate box, without being obstructed by the adjacent first substrate box, It is possible to ensure sufficient breathability. As a result, it is possible to efficiently exhaust the gas and suppress deterioration of the heat dissipation performance.

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

As a result, it becomes easier to secure a larger space for installing both board boxes without impairing the heat dissipation performance of the second board box.

Of course, since it is not necessary to dispose both board boxes in the front-rear direction, it is possible to effectively use the installation space in the front-rear direction. That is, it is possible to suppress the expansion of the installation space of the board box and the like in the depth direction, efficiently and efficiently arrange the board box and the like in a more compact manner. As a result, while ensuring the expandability for adding a new device, it is possible to satisfactorily deal with the case where the installation space such as the island facility of the game hall where the game machine is installed is relatively small.

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

According to the above means 5, the outside air can be efficiently applied to the electronic component mounted on the second control board. Further, since the cover body is arranged so as to face the air blower on the front wall portions of both substrate boxes, that is, on the intake side of the air blower, foreign matter such as dust or dust can be prevented from entering the second substrate box. Can be suppressed. As a result, it is possible to achieve both suppression of intrusion of foreign matter such as dust and dirt and improvement of cooling efficiency of electronic components.

Means 6. The air blower is arranged to face a specific electronic component among the electronic components mounted on the second control board, and blows air toward the specific electronic component. Amusement machine.

According to the above means 6, the specific electronic component can be intensively cooled, so that the specific electronic component can be efficiently maintained at an appropriate temperature.

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

If the cover body is arranged close to both board boxes to prevent the connector from being detached as described above, the exhaust performance (heat dissipation performance) may deteriorate. In this respect, according to the above means 7, by providing the cover body with the exhaust hole, it is possible to suppress the deterioration of the exhaust performance from the exhaust port of the chamfered portion.

Means 8. In any one of the means 1 to 7, the first board box and the second board box are arranged such that the front-rear direction positions of the front wall portions are the same or substantially the same position. The game machine described.

With the structure of the means 8 described above, since the gap with the cover body is unlikely to occur, the function and effect of the means 1 can be further improved. Also, both board 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 do not match due to structural reasons such as the layout configuration, place a spacer, etc. on the back side of one board box. The positions of both surface walls will be adjusted. At this time, in some cases, a relatively large space can be secured on the back side of one of the substrate boxes. In this case, for example, it becomes easy to cope with the case where a new device is added, and the versatility becomes high when changing the model of the game 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 expansion of the installation space in the depth direction can be suppressed, while the space behind the one board box is effective. Can be used for.

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

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

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

According to the above means 10, if the first substrate box is opened by any chance, some mark remains on the sealing means, and by confirming it, fraud can be easily found. Therefore, in addition to direct prevention of fraudulent acts, it is possible to prevent fraudulent acts from the aspect of early detection of fraudulent acts.

Here, the back wall portion 267 of the main control device 261 (board box 263) and the top portion of the fan duct portion 663 of the display control device 45 are located at substantially the same position in the front-rear direction (left-right direction in FIG. 15). This suppresses expansion of the installation space of the main control device 261 and the display control device 45, etc. in the depth direction, efficiently arranges the main control device 261 and the display control device 45 in a compact manner without waste, and This is to secure the widest space on the back side of the board mounting portion 201b. By securing a relatively large space on the back side of the board mounting portion 201b, it becomes easy to deal with, for example, a case where a larger accessory is placed on the game board 30 side, and versatility is improved when changing models. In this embodiment, since the fan duct portion 663 projects rearward from the back wall portion 655 of the unit cover 654, the configuration is as described above, but if the fan duct portion 663 does not project. It is preferable that the back wall portion 267 of the main control device 261 and the back wall portion 655 of the display control device 45 have substantially the same position in the front-rear direction.

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. It is configured to leave traces of. As a result, it can be easily found that the board box 263 has been illegally opened. The sealing units in the present embodiment are configured by the sealing units 264A and 264B.

The sealing units 264A and 264B may have any configuration as long as they can connect the box base 265 and the box cover 266 in an unopenable manner. However, in this embodiment, the left sealing unit 264A has three sealing members connected to each other. The sealing unit 264B on the right side has two sealing members connected to each other. The box base 265 and the box cover 266 are connected in an unopenable manner by inserting locking claws into the long holes of these sealing members. The sealing processing 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 the unauthorized opening is performed. It is possible to perform the opening/sealing process again even after the opening is once performed. That is, the sealing process is performed by inserting the locking claws into the elongated holes of at least one of the five sealing members that form the sealing units 264A and 264B. Then, when the substrate box 263 is opened due to a malfunction of the accommodated main substrate 262, the connection between the sealing member in which the locking claw is inserted and the other sealing member is cut. After that, when the sealing process is performed again, the locking claw is inserted into the long hole of the other sealing member. If a history of the fact that the board box 263 has been opened is left in the board box 263, it can be easily found by looking at the board box 263 that the illegal opening has been made.

Further, as shown in FIGS. 7 and 15, a plurality of terminal portions 701, 702, 703, 704, 705 for connecting connectors of various cable connectors are provided in the left-right direction near the upper edge portion of the main board 262. It is lined up alongside. Each of the terminal portions 701 to 705 is formed so as to project from the main board 262, and is exposed to the outside of the board box 263 via a hole portion 266b opened in a recess (retraction portion) 266a formed in the upper portion of the box cover 266. Has become. Note that the terminal portions 701 to 705 and the cable connectors connected thereto have the same and general configurations, and therefore, for the sake of convenience, the illustration of the cable connectors is omitted in FIG. Shows only the terminal portion 703 and the cable connector CC connected thereto as an example.

The terminal portion 701 is connected to the other connector of the cable connectors, one of which is connected to the sub control device 560. 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.

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

As described above, since the terminal portions 701 to 705 project toward the back side of the pachinko machine 10, the connector CN of the cable connector CC or the like is attached to the front side of the pachinko machine 10 (leftward in FIG. 15). Therefore, the connector CN and the like are detached from the back side of the pachinko machine 10 (rightward in FIG. 15).

In the closed state of the back pack 351 (back pack unit 203) described later, at least the cable connector CC connected to each of the terminal portions 701 to 705 is covered with the connector CN or the like in the removal direction side to protect it described later. The cover portion 354 is arranged. As shown in FIG. 15, the distance between the protective cover portion 354 and the connector CN and the like in the closed state of the back pack 351 is shorter than the distance (insertion amount) required to remove the connector CN and the like. Therefore, the connection of the connector CN and the like of the cable connector CC cannot be released unless the back pack 351 is opened. That is, even if the connector CN or the like is illegally removed and a malicious action such as mounting a so-called hanging substrate or replacing the main substrate 262 with an unauthorized product is performed, the protective cover portion 354 interferes with the connector. Since it is virtually impossible to remove the CN, it is possible to prevent such acts. Moreover, in the present embodiment, since the back pack unit 203 is configured to be locked, the effect becomes more reliable.

Among the various cable connectors described above, the connector CN of the cable connector CC of the first board surface relay board 226, the cable connector of the first trigger response 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. The main controller 261 is passed from the rear side to the rear side of the main controller 261 through a gap between the main controller 261 and the display controller 45.

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

This is because the display control device 45 and the main control device 261 are arranged adjacent to each other and the gap between them is narrowed, so that the cable CA and the like of the cable connector CC is prevented from being excessively bent. It is a device for doing. That is, in the display control device 45 (unit cover 654), the inclined wall portion 665 which is chamfered at the lower rear corner portion adjacent to the main control device 261 is formed. A space for allowing the curve of the cable CA of the cable connector CC or the like, 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 cables CA and the like of the cable connector CC can be flexibly wired without being excessively bent, and the cable connector CC is adversely affected. It can be reduced.

Further, since the length of the cable CA or the like of the cable connector CC is usually set to be longer in consideration of the connection work with the above-mentioned terminal portions 701 to 705, the excess portion of the cable CA or the like is temporarily displayed. If the cable 45 bends toward the main controller 261 instead of the device 45, the excess portion of the cable CA or the like may hang down and stick out from the lower end of the protective cover 354. In such a state, a fraudulent act such as “hanging” as described above may be performed, and the inside of the main control device 261 may be hindered from being visually recognized, which may delay early detection of a fraudulent act or the like. 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, the deflection toward the display control device 45 side is promoted, and thus such a problem is unlikely to occur. ..

The second control board unit 202 includes a payout control device 311, a firing control device 312, a power supply device 313, and a card unit connection board 314. As is well known, the payout control device 311, the firing control device 312, and the power supply device 313 are provided with a CPU that is the center of control, and a control board including ROM, RAM, various ports, and the like, and the payout control of the payout control device 311. The substrate controls the payout of prize balls and rental balls. Further, the firing control board of the firing control device 312 controls the firing device and the like in accordance with the operation of the handle 18 by the player, and the power supply board of the power supply device 313 generates a predetermined power supply voltage required by various control devices and the like. Is output.

The payout control device 311, the firing control device 312, and the power supply device 313 are also housed in the corresponding board boxes 315, 316, and 317. However, the firing control device 312 (the board box 316) is arranged on the back side of the power supply device 313 (the board box 317). Further, the board box 315 accommodating the payout control device 311 is provided with a sealing unit similar to the above-mentioned main control device 261, so that the trace of the opened board 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 dispensing error such as a ball clogging of the dispensing motor unit occurs, the dispensing motor is rotated in the normal and reverse directions to eliminate the ball clogging (return to a normal state).

Further, the power supply device 313 is provided with a RAM erase switch 323. The pachinko machine 10 has a backup function and can retain the state at the time of power failure even if a power failure occurs, and can restore the state at the time of power failure at the time of recovery from the power failure (power recovery). it can. Therefore, if the power is shut off in the normal procedure (for example, when the game hall is closed), the state before the power shutdown is stored and retained. Therefore, if you want to return to the initial state when the power is turned on, hold down the RAM erase switch 323 and turn on the power. Throw in.

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

The protective cover portion 354 has a shape in which the left and right side surfaces and the upper surface are closed and the front surface and the lower surface are open, and has a size sufficient to at least surround the variable display device unit 35. However, in the present embodiment, the main control device 261 is also configured to cover a part thereof. The protective cover portion 354 protects the variable display device unit 35 from a game ball or the like falling from an upper tank 355 or the like described later. The protective cover portion 354 constitutes the cover body in this embodiment.

Further, a large number of ventilation holes 354a are provided on the back surface of the protective cover portion 354. However, the vent hole 354a is not provided at a position behind the cooling fan 675 of the display control device 45. This is to suppress the entry of foreign matter such as dust or dirt into the display control device 45. On the other hand, the vent hole 354a functioning as an exhaust hole is provided at a position behind 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. It is provided. Further, in order to suppress the illegal acts of the cable connector CC on the connector CN or the like, the vent hole 354a is not provided at the rear position of the connector CN or the like.

The payout mechanism 352 is arranged so as to bypass the protective cover 354. That is, above the protective cover portion 354, a tank 355 having an opening on the upper side is provided, and the tank 355 is successively replenished with game balls supplied from the island facility of the game arcade. Below the tank 355, for example, a tank rail 356 having two rows of ball passages in the horizontal direction and gently sloping toward the downstream side is connected, and further, a case rail 357 is vertically provided 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 appropriately paid out by a predetermined electric configuration of the payout motor 358a and the like. Then, the game balls paid out from the payout device 358 are supplied to the upper plate 19 and the like.

Further, in the payout mechanism unit 352, a payout relay board 381 that relays a signal of a payout command from the payout control device 311 to the payout device 358 is installed, and a power switch board 382 that takes in the main power from the outside is installed. There is. Main power of 24 V AC, for example, is supplied to the power switch substrate 382 via a voltage converter, and the power is turned on or off by a switching operation of the power switch 382a.

This is an area for storing the values of stack pointers, registers, I/O, etc. Writing to the backup area 503a is performed by NMI interrupt processing started by inputting a stop signal to the NMI terminal (non-maskable terminal) (this NMI interrupt causes the state of the main controller 261 at the time of power off to the backup area 503a of the RAM 503). (Restored) is executed when the power is cut off due to the occurrence of a power failure or the like, and conversely, the restoration of each value written in the backup area 503a is performed when the power is turned on (including power on when the power is removed. The same applies hereinafter). Executed in. The NMI terminal (non-maskable interrupt terminal) of the CPU 501 is configured to receive a power failure signal SK1 output from a power failure monitoring circuit 542, which will be described later, when the power is cut off due to a power failure or the like. Upon occurrence, the power failure process (NMI interrupt process) is immediately executed.

An input/output port 505 is connected to the CPU 501 having the ROM 502 and the RAM 503 built therein through a bus line 504 including an address bus and a data bus. The input/output port 505 is composed of the terminal portions 701 to 705 and the like.

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, 531. It has and. The input/output port 554 of the sub control device 560 is connected to the input port 527. A CPU 521, a program ROM 522, a work RAM 523, and a 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, which is 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, analyzes the received command, or performs predetermined arithmetic processing based on the received command to control the VDP 526 ( Specifically, the internal command generation for the VDP 526 is performed. Thereby, the display control in the decorative symbol display device 42 is performed.

The program ROM 522 is a memory that stores various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 is a memory that temporarily stores work data and flags used when the CPU 521 executes various programs. Is.

The video RAM 524 is a memory for storing display data displayed on the decorative symbol display device 42, and by rewriting the contents of the video RAM 524, the display content of the decorative symbol display device 42 is changed. The character ROM 525 is a memory that stores character data such as a design displayed on the decorative design display device 42.

The VDP 526 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal drive circuit) incorporated in the decorative pattern display device 42. Since the VDP 526 is formed as an IC chip, it is also called a "drawing chip", and the substance thereof should be called a microcomputer chip having a firmware dedicated to drawing processing. The VDP 526 adjusts the respective timings of the CPU 521, the video RAM 524 and the like to intervene in the reading and writing of data, and also reads the display data stored in the video RAM 524 at a predetermined timing to display it on the decorative symbol display device 42.

The power supply device 313 also includes a power supply unit 541 that supplies electric power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to a power failure, etc., and a RAM erase switch circuit 543 connected to the RAM erase switch 323. It has and. The power supply unit 541 supplies necessary operating power to each of the main control device 261 and the payout control device 311 through a power supply path (not shown). As an outline, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside and generates +12V power supply for driving various switches and motors, +5V power supply for logic, backup power supply for RAM backup, and the like. The +12V power source, the +5V power source, and the backup power source are supplied to the main control device 261, the payout control device 311 and the like. The firing control device 312 is supplied with operating power (+12V power supply, +5V power supply, etc.) 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 outage monitoring circuit 542 monitors the voltage of DC stable 24 V which is the maximum voltage output from the power supply unit 541, and when this voltage is less than 22 V, determines that a power outage (power outage) has occurred, The power failure signal SK1 is output to the main controller 261 and the payout controller 311. By the output of the power failure signal SK1, the main controller 261 and the payout controller 311 recognize the occurrence of the power failure and execute the power failure time processing (NMI interrupt processing).

It should be noted that the power supply unit 541 normally outputs the output voltage of 5 V, which is the drive voltage of the control system, for a sufficient time to execute the process at the time of power failure even after the voltage of DC stable 24 V becomes less than 22 V. It is configured to maintain a value. Therefore, the main controller 261 and the payout controller 311 can normally execute and complete the power failure process.

The RAM erasing switch circuit 543 is a circuit that takes in the switch signal of the RAM erasing switch 323 and clears the backup data of the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 according to the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs the 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 erasing switch 323 being pressed down (including turning on the power by eliminating the power failure), the data in the RAMs 503 and 513 in the main controller 261 and the payout controller 311 are cleared. It

As described above in detail, in the present embodiment, when the back pack 351 is closed, at least the cable CN connected to these terminal portions 701 to 705 is protected by covering the connector CN or the like in the direction of removal. The cover portion 354 is arranged. The distance between the protective cover portion 354 and the connector CN and the like in the closed state of the back pack 351 is shorter than the distance (insertion amount) required to remove the connector CN and the like. Therefore, the connection of the connector CN and the like of the cable connector CC cannot be released unless the back pack 351 is opened. That is, even if the connector CN or the like is illegally removed and a malicious action such as mounting a so-called hanging substrate or replacing the main substrate 262 with an unauthorized product is performed, the protective cover portion 354 interferes with the connector. Since it is virtually impossible to remove the CN, it is possible to prevent such acts. Moreover, in the present embodiment, since the back pack unit 203 is configured to be locked, the effect becomes more reliable.

Further, in the present embodiment, the display control device 45 and the main control device 261 are arranged adjacent to each other and the gap between them is narrowed, so that the cables CA and the like of the cable connector CC are excessively bent. The device has been devised to prevent such damage. That is, in the display control device 45 (unit cover 654), the inclined wall portion 665 which is chamfered at the lower rear corner portion adjacent to the main control device 261 is formed. A space that allows bending of the cable CA of the cable connector CC, that is, an escape 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 cables CA and the like of the cable connector CC can be flexibly wired without being excessively bent, and the cable connector CC is adversely affected. It can be reduced.

As a result, it is possible to effectively use the installation space of the main control device 261 and the like, and to suppress fraudulent activity.

Further, in this embodiment, the oblique exhaust port 666 is formed in the inclined wall portion 665 of the display control device 45. By adopting such a configuration, the air permeability of the display control device 45 can be sufficiently ensured without being obstructed by the adjacent main control device 261. As a result, it is possible to efficiently exhaust the gas and suppress deterioration of the heat dissipation performance.

In other words, it is possible to expand the display control device 45 and the main control device 261 until they are substantially in contact with each other, and it is possible to cope with an increase in the size of the control board, and to effectively use the limited installation space. be able to. Of course, since it is not necessary to dispose the display control device 45 and the main control device 261 in the front-rear direction, it is possible to effectively use the installation space in the front-rear direction. That is, expansion of the installation space of the main control device 261 and the like in the depth direction can be suppressed, and the main control device 261 and the like can be disposed more efficiently and more compactly without waste. As a result, while ensuring the expandability for adding a new device, it is possible to satisfactorily deal with the case where the installation space such as the island facility of the game hall where the game machine is installed is relatively small.

It should be noted that the present invention is not limited to the contents described in the above embodiment, and may be implemented as follows, for example.

(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 in the adjacency relationship between the display control device 45 and the main control device 261 has been shown. However, the present invention is not limited to this. For example, the two are in opposite positions, that is, the main control device 261 includes a cooling fan similar to the cooling fan 675, and the main control device 261 has the same inclined wall portion 665 and diagonal exhaust port 666. A configuration in which an inclined wall portion and an oblique exhaust port are provided may be used. Further, the present invention may be applied in the relation of other control devices such as the relation between the main control device 261 and the payout control device 311. Of course, it can be applied not only to the one-to-one relationship but also to the one-to-many relationship. For example, in addition to the display control device 45 being disposed adjacently above the main control device 261, the payout control device 311 is disposed adjacently below the main control device 261, and the inclined wall portion in the payout control device 311. The inclined wall portion and the oblique exhaust port similar to the 665 and the oblique exhaust port 666 may be formed.

Of course, it may be applied to a configuration in which the control devices that are not provided with the 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 above-described embodiment, the cooling fan 675 is arranged to face the VDP 526 so as to blow air toward the VDP 526. Not limited to this, the cooling fan 675 may be provided so as to blow air toward at least the inside of the display control device 45. For example, it may be disposed so as to face the mounting surface of the display control board 650 at a position deviated from the VDP 526. Therefore, if 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 project from the back wall portion 655 of the unit cover 654, and a plurality of ventilation holes 664 as intake ports are formed at the top thereof. Not limited to this, 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. With this configuration, the display control device 45 and the main control device 261 can be arranged more compactly in the front-back direction than in the above embodiment.

Further, the cooling fan 675 may be configured to have an intake port having the same size as the cooling fan 675 so that the entire cooling fan 675 faces the outside. By doing so, the intake performance can be improved. However, in order to improve safety, it is preferable that a plurality of small vent 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) In the above embodiment, the display control device 45 and the main control device 261 are arranged in close proximity, but the invention is not limited to this, and both may be arranged in contact. 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, hot air is not blown to the main controller 261 below, so that the influence on the main controller 261 can be reduced. Furthermore, since it is not necessary to secure a ventilation space between the display control device 45 and the main control device 261, both control devices 45 and 261 can be brought into close contact with each other, and the limited installation space can be effectively utilized. You can In this case, at least one of the control devices 45 and 261 may be provided with a recess 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 that guides the cable CA and the like of the cable connector CC to the inclined wall portion 665 side. For example, as shown in FIG. 17, the inclined wall portion 665 in which the oblique exhaust port 666 is omitted may be provided with a hooking portion 900 for hooking the cable CA or the like. Thereby, the cable CA or the like can be guided toward the side of the inclined wall portion 665, that is, in the direction opposite to the main control device 261, and the cable CA or the like can be promoted to be in a curved state. The bending suppression effect is more reliably exhibited.

(F) You may implement as a pachinko machine of a type different from the said embodiment. In addition to pachinko machines, it is also used as an arrangement ball machine, various game machines such as sparrow balls, a spinning machine such as a slot machine, and a game machine in which a slot machine and a pachinko machine are combined.
