Description

  The present invention relates to a gaming machine.

  In this type of gaming machine, for example, in a pachinko machine, a gaming ball is launched into the gaming area, and when a gaming ball is won at various winning holes in the gaming area, a predetermined number of gaming balls are paid out accordingly. Further, for example, a symbol display unit made up of a liquid crystal display device or the like is installed in the center of the game area, and a plurality of columns of symbols are variably displayed by the symbol display unit. In this case, the symbol variation display by the symbol display unit is started with the winning of the predetermined prize opening (start winning award) as a trigger, and thereafter the symbol variation display is stopped through the variation display by the predetermined variation pattern. If the symbols are the same when the stop symbol of each symbol row is determined, the game proceeds to a special game state (big hit state) and a large amount of game balls are paid out. The probability of transitioning to the special gaming state is set with a relatively low probability, and the normal state is left when not transitioning to the special gaming state.

  The pachinko machine has a so-called main board that controls the main control of the game. With the main board, the game ball is paid out in accordance with winning a prize, and each game state is changed to a normal state or a special game state. Whether to do so is controlled. In the pachinko machine, in addition to the main board, a payout control board for controlling the payout of game balls, a display control board for controlling the fluctuation display of the symbols in the symbol display unit, and an audio device or a lamp device installed in the gaming machine. An audio lamp control board for performing effects is installed.

  As described above, the pachinko machine is equipped with a plurality of control boards (control devices) including the main board, and the control board is mounted on the gaming machine main body via the pedestal device. In this case, there is an advantage that the control board is attached in a stable state.

  In addition, in recent game machines, various efforts have been made to diversify the game effects in order to improve interests, etc., and on the back side of the pachinko machine, there are a lot of various equipment and board devices such as relay boards. Arranged. For this reason, the pedestal device is provided so as to be separated from the back side of the gaming machine (for example, the game board), and various kinds of accessories and the space between the pedestal device and the back of the gaming machine (the space behind the pedestal member) are used. Efficient arrangement of substrate devices has been studied. In addition, if a back space of the pedestal device is provided, there is a possibility that an illegal act such as inserting a hand or a tool from the outside into the back space and causing the gaming machine to malfunction will be performed. Therefore, in order to prevent a hand or a tool from being inserted into the back space, a technique for providing a shielding portion on the base member has been proposed (see, for example, Patent Document 1).

However, when the pedestal device is provided so as to be separated from the back side of the gaming machine (for example, the game board) as described above, there is a concern that the space behind the pedestal device may be misused for improper purposes. Specifically, there is a concern that an illegal substrate or the like may be attached to the space. Even if the shielding portion is provided as described above, the possibility of fraud remains. Therefore, the countermeasure against the fraud is desired.

The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers the section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137 A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

  Further, on the lower back side of the rail cover 140, a ridge 142 extending in an arc shape along the inner edge and protruding rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 13 is closed. Therefore, for example, even if an attempt is made to cheat by inserting a wire or film from the gap between the front door frame 13 and the main body frame 12, the wire or film is allowed to enter the game area inside the ball guide passage. Becomes very difficult. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented. The protrusion 142 may be formed in a wider range, for example, along the entire area of the inner edge of the rail cover 140. According to such a configuration, it becomes difficult to infiltrate a wire, a film, or the like in a wider range, It is possible to more reliably prevent fraudulent acts that are performed using wires or films.

The board surface relay board 226 and the special winning opening relay board 227 are connected to the main controller 271. The operation port switch 224 is directly connected to the main controller 271 without using a relay board. Although not shown in the drawings, the variable winning device 32 is driven with a large winning opening solenoid for opening the opening / closing door of the large winning opening and a distribution plate for distributing the winning balls to a specific area or other areas. A winning ball sorting plate solenoid is provided, and the operating port 33 is provided with an operating port solenoid for opening an electric accessory attached thereto.

  The detection results detected by the winning detection mechanism are taken into the main control device 271, and a payout command (the number of game balls to be paid out) corresponding to the winning situation at each time is sent from the main control device 271 to the payout control device 311. Sent. The payout of the predetermined number of game balls is executed by the output of the payout control device 311. Here, in the conventional so-called evidence ball system, the game balls won in various winning openings are once collected in a winning ball processing device, and the winning ball processing device confirms the presence of the winning balls one by one and then pays out. However, in the pachinko machine 10 according to the present embodiment, a lot of game balls are paid out because the winning of the game balls is electrically detected for each prize opening and the payout is immediately performed. In this case, the payout can be performed promptly, and a winning ball processing apparatus is not required.

  The collective board unit 215 is provided with a board external terminal board 230 at the upper right part thereof. The panel external terminal board 230 has an output terminal for outputting a signal every time the variation of the first symbol is stopped (determined), and an output terminal for outputting a signal during a big hit or during the reduction of the variation time of the first symbol.

Since the back pack unit 203 stores a large amount of game balls in its upper part, the fixtures 241 and 242 for supporting the upper part of the back pack unit 203 have a particularly strong strength. Desirably, a rotating fixture is used in the present embodiment.

  As described above, a long bearing fitting 235 is provided on the left and right side portions (right side in FIG. 9) of the main body frame 12, while the left and right other side portions (left side in FIG. 9) of the main body frame 12 are locked. A device is provided. The locking device includes a base frame 247 that extends in the vertical direction and is fixed to the main body frame 12, and a long interlocking rod 248 that is assembled to the base frame 247 so as to be movable in the vertical direction. The cylinder lock 91 is integrated in the lower part of the cylinder. The interlocking rod 248 moves in either the up or down direction by operating the cylinder lock 91. The interlocking bar 248 is provided with a pair of upper and lower bar brackets 249 having a hook shape. When the main body frame 12 is closed with respect to the outer frame 11, the bar bracket 249 is attached to the support bracket ( (Not shown) and locked by a locking device. In this case, when the interlocking rod 248 moves upward by the operation of the cylinder lock 91, the locking of the main body frame 12 with respect to the outer frame 11 is released. On the contrary, when the interlocking rod 248 moves downward by the operation of the cylinder lock 91, the locking of the front door frame 13 with respect to the main body frame 12 is released.

  In the above-described configuration in which the bearing bracket 235 and the locking device (base frame 247, interlocking rod 248, etc.) are distributed to the left and right sides of the main body frame 12, the bearing bracket 235 and the locking device (base frame 247, interlocking rod 248, etc.) are arranged. The game board 30 is attached to the main body frame 12 so as to have a width that leaves an area for placing a). As described above, the game area is also expanded by this.

  In the lower right portion of the game board 30 on the back surface of the main body frame 12, a game ball distribution unit 245 for distributing game balls paid out by a payout mechanism, which will be described later, to any of the upper plate 23, the lower plate 16 or the discharge passage 218 is provided. It has been. The game ball distribution unit 245 has a left opening 245a that communicates with the upper plate 23 through the first discharge port 66, and a central opening 245b that communicates with the lower plate 16 through the second discharge port 67, and the right opening. Each passage is formed so that the portion 245c communicates with the discharge passage 218. The game ball distribution unit 245 is firmly attached to the main body frame 12 with screws or the like. Therefore, the floating at the installation site of the game ball distributing unit 245 is prevented, and an illegal act caused by entering a wire, a film, or the like from the gap can be prevented. Note that a synthetic resin speaker box 246 is attached to the lower end portion of the main body frame 12 to surround the back of the speaker 20 installed on the back side of the back wall panel 17, and the speaker box 246 transmits the speaker sound to the rear. The sound quality in the low frequency range is improved by functioning so as not to miss.

  Next, the configuration of the first control board unit 201 will be described with reference to FIGS. 13 is a front view of the first control board unit 201, FIG. 14 is a rear view of the unit 201, FIGS. 15 and 16 are perspective views of the unit 201, and FIG. 17 is an exploded perspective view of the unit 201. Of the members constituting the first control board unit 201, FIG. 18 shows the configuration of the main controller 271, FIG. 19 shows the configuration of the mounting base 251, and FIG. 20 shows the configuration of the spacer member 285. FIG. 21 is a front view of a state in which the first control board unit 201 is attached to the back surface of the game board 30.

  The first control board unit 201 has a mounting base 251 as a base member having a substantially L shape, and the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251. The main control device 271 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port for communicating with various devices, and a random number used in various lotteries. A main substrate including a generator, a clock pulse generation circuit used for time counting and synchronization, etc. is provided, and the main substrate is accommodated in a substrate box 273 as an encapsulating means made of a transparent resin material or the like. Configured. The board box 273 includes a substantially rectangular parallelepiped box base (front case body) and a box cover (back case body) that covers an opening of the box base. The box base and the box cover are connected so as not to be unsealed by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

  The sealing unit 274 can be applied to any structure as long as it connects the box base and the box cover so that they cannot be opened. However, here, as shown in FIG. 18 and the like, five sealing members are arranged side by side. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit 274 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation quickly and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 274. When the substrate box 273 is opened, such as when a failure occurs in the accommodated main substrate or when the main substrate is inspected, the connection between the sealing member into which the locking claw is inserted and the other sealing member is disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 273 is left in the substrate box 273, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 273.

  Further, in the substrate box 273, the short side portion opposite to the sealing unit 274 is provided with sealing portions 275 for sealing the substrate box 273 at two upper and lower portions separately from the sealing unit 274.

  A plurality (four in this embodiment) of coupling pieces 276 are provided on the upper end portion of the substrate box 273 so as to protrude upward. The coupling piece 276 is coupled to the box base (or box cover) of the substrate box 273 by the coupling portion 276a. When the coupling piece 276 is used as a sealing portion (caulking portion) as will be described later, the coupling portion 276a is broken. The tool can be broken.

  As shown in FIG. 18B, a columnar protrusion 277 is provided at one place on the back surface of the substrate box 273, and rotationally-operated locking tools 278 as fastening members are provided at two left and right places. Is provided. The protrusions 277 are formed at individual specific positions (for example, any one of the five specified positions) for each of a plurality of types of main control devices 271. The locking tool 278 can be rotated by a support shaft 278a erected on the back surface of the substrate box 273, and the locking tool 278 is rotated within an angle range of 90 degrees. In this case, the latching tool 278 is rotated between a position that is a horizontal character and a position that is a vertical character.

  The sound lamp control device 272 includes, for example, a CPU for controlling sound and lamp display in accordance with instructions from the main control device 271 or the display control device 214, and a sound lamp control board including ROM, RAM, various ports, and the like. The sound lamp control board is housed in a board box 281 made of a transparent resin material or the like. A power relay board 282 is mounted on the sound lamp control device 272, and the power of the power supply device 313 is supplied to the display control device 214 and the sound lamp control device 272 via the power relay board 282. . The board box 273 of the main controller 271 and the board box 281 of the sound lamp controller 272 both correspond to case members.

  In FIG. 19, the mounting base 251 is made of synthetic resin such as polycarbonate resin, and is colorless and transparent as a whole. However, the mounting base 251 may be colored in green, blue, etc., and may be opaque or translucent. The mounting base 251 is provided with two board mounting portions 252 and 253 having a flat plate shape. These substrate mounting portions 252 and 253 extend in directions orthogonal to each other in the vertical and horizontal directions, and are formed with steps in the front-rear direction of the pachinko machine 10. Specifically, one substrate mounting portion 252 is a substantially rectangular flat plate portion extending in the left-right direction, and the other substrate mounting portion 253 is a substantially rectangular flat plate portion extending in the vertical direction. The board mounting portions 252 and 253 have board mounting surfaces 252a and 253a on the front side of the mounting base 251 (the side facing the back of the pachinko machine in the state of being installed in the pachinko machine 10), and these board mounting surfaces 252a. , 253a is provided with a step of about 20 to 30 mm so that the substrate mounting surface 252a of the substrate mounting portion 252 is on the front side when viewed from the front side of the mounting base 251.

  The substrate mounting portion 252 has a standing portion 254 standing on the substrate mounting surface 252a side at the lower end portion, and a plurality (four in this embodiment) of coupled pieces 255 at the upper end portion. ing. In addition, a plurality of (five in the present embodiment) alignment holes 256 are formed side by side in the substrate mounting portion 252 and horizontally elongated through holes 257 are formed at two left and right positions. At this time, each of the alignment holes 256 is a hole having excisable pieces that can be excised, and one of the plural alignment holes 256 is punched and opened in accordance with the main controller 271 used each time. Is done. As a result, an assembly error of the main controller 271 to be mounted on the board mounting portion 252 is prevented.

  When the main control device 271 is mounted on the board mounting portion 252, the main control device 271 is arranged in a landscape orientation. At this time, with the lower side of the main control device 271 placed on the upright portion 254, the locking tool 278 is inserted into the left and right through holes 257 of the board mounting portion 252, and the alignment holes 256 (a plurality of the same holes are provided). The main controller 271 is mounted on the board mounting portion 252 so that the protrusion 277 is inserted into the open hole). Then, the locking tool 278 is rotated 90 degrees behind the board mounting portion 252 and operated to the locked position. The main controller 271 can be mounted on the board mounting portion 252 so as not to be removed by the rotation operation of the locking tool 278. In this case, the main controller 271 cannot be removed unless the locking tool 278 is rotated again from the back side of the first control board unit 201 to return to the unlock position (unlocked). A deterrent effect is obtained against fraudulent acts such as board removal.

  Further, in a state where the main control device 271 is mounted on the board mounting portion 252, the coupling piece 276 of the main control device 271 and the coupled piece 255 on the mounting base 251 overlap with each other in the front-rear direction. In this case, a sealing process is performed between the main controller 271 and the mounting base 251 by screwing a sealing screw into one of the four sets of the coupling piece 276 and the coupled piece 255. Although illustration is omitted, the sealing screw is a so-called breaking screw that breaks the head when a load exceeding a predetermined tightening force is applied when tightening with a tightening tool such as a screwdriver. Since the screw head is broken at the time of sealing, the screw loosening operation by a driver or the like becomes impossible thereafter. In this case, in order to release the seal, the connecting portion 276a of the coupling piece 276 must be broken, and the history of seal release remains due to the breakage.

  Instead of the breaking screw, it is also possible to use a so-called one-way screw (also referred to as a one-way screw) that can be screwed in a predetermined tightening direction but cannot be screwed in the opposite loosening direction. The board mounting portion 252 is provided with a sealing screw storage portion 258 for storing sealing screw stock.

  In addition, an audio lamp control device 272 is arranged on the other board mounting portion 253 in a vertically long direction. At this time, the sound lamp control device 172 is positioned and fixed by screws or the like at a plurality of locations.

  In a state in which the mounting base 251 is attached to the back side of the game board 30, the two board mounting parts 252 and 253 are separated from the game board 30. As a configuration for that, the board mounting parts 252 and 253 have a board. Legs extending on the side opposite to the mounting surfaces 252a and 253a (the back side of the mounting base 251) are provided. The leg portion roughly includes a lower leg portion 261 provided on the lower side of the mounting base 251 and an upper leg portion 262 provided on the upper side of the mounting base 251. Specifically, the lower leg portion 261 includes left and right side portions 261a and 261b and a lower side portion 261c provided between the side portions 261a and 261b. The left and right side portions 261a and 261b have different dimensions in the length direction as leg portions, and the side portion 261a is longer than the side portion 261b. This difference is due to a difference in height position between the two board mounting portions 252 and 253. The lower leg 261 composed of the left and right side portions 261a and 261b and the lower side portion 261c is integrally formed continuously, and serves as a shielding portion for shielding the rear portions of the board mounting portions 252 and 253.

  In the lower leg portion 261, one side portion 261 a is provided with a pair of upper and lower retaining pins 263. By attaching the retaining pins 263 to the bearing fitting 231 of the collective plate unit 215, One control board unit 201 is cantilevered so as to be rotatable with respect to the game board 30. Similarly, a binding tool 264 for bundling electric wires extending from each control device and the game board 30 is attached to the side portion 261a. The other side portion 261b is provided with a pair of upper and lower nai latches 265 as fasteners to be fitted into the fastening holes 232 of the collective plate unit 215. In addition, since the same side part 261a is a site | part which comprises the spindle part of the 1st control board unit 201, the wall board has a double structure for the reinforcement.

  The upper leg portion 262 is provided at the upper end portion of the board mounting portion 253, and a long hole 267a is formed in the base end portion 267 thereof. The long hole 267 a is provided at a position corresponding to the locking claw piece 233 of the collective plate unit 215.

  Therefore, when the mounting base 251 is attached to the back side of the game board 30 (actually, the collective board unit 215), the tips of the lower leg 261 and the upper leg 262 are on the back side of the game board 30 (collection). The plate unit 215). At this time, the ny latch 265 is fitted into the tightened hole 232, and the locking claw piece 233 is locked by the long hole 267a, whereby the first control board unit 201 is fixed to the game board 30. It should be noted that the bearing fitting 231 and the latch pin 263 are in the support shaft portion M1, the fastened hole 232 and the ny latch 265 are in the fastening portion M2, and the locking claw piece 233 and the long hole 267a are in the locking claw portion M3, respectively. Equivalent to.

  As described above, since the two board mounting portions 252 and 253 are configured to be separated from the game board 30 in a state in which the attachment base 251 is attached to the game board 30, A predetermined space region is formed behind (on the opposite side to the substrate mounting surfaces 252a and 253a). In such a case, by using the space area, various objects provided on the back side of the game board 30 (for example, a start winning device, a variable winning device, etc.), a board device such as a relay board, and various wirings can be arranged efficiently It can be done.

  However, on the other hand, there is a concern that the space area behind the mounting base 251 may be misused for illegal purposes. Specifically, there is a concern that an illegal substrate or the like may be attached to the space area. Note that the space behind the mounting base 251 is shielded by the shielding function of the lower leg 261, and thus it is considered that insertion of hands and tools is prevented. It is also possible to create an installable area. Moreover, the demerit that it becomes difficult to find the illegal board etc. once attached by the shielding function of the lower leg part 261 is also assumed.

  Therefore, in the present embodiment, a countermeasure against fraud is taken by arranging a spacer member 285 in a space area behind the mounting base 251 and filling the space area. The configuration of the spacer member 285 will be described with reference to FIG.

  As shown in FIG. 20, the spacer member 285 has a hollow block-like cubic shape as a whole, and the front side (mounting base 251 side) of the opposing front and back sides is a closed surface. On the other hand, the back side (the side opposite to the mounting base 251) is an open surface. The spacer member 285 is formed of a colorless and transparent synthetic resin material. The area of the front side surface of the spacer member 285 substantially matches the area of the board mounting portion 252 of the mounting base 251. Further, the thickness of the spacer member 285 is substantially the same as the length of the leg portion of the mounting base 251 or slightly shorter than the length of the leg portion of the mounting base 251. Therefore, the spacer member 285 has substantially the same occupied volume as the back space of the board mounting portion 252 of the mounting base 251, and is just fit in the back space.

  However, it is also possible to reverse the closed surface and the open surface among the opposing front and back sides of the spacer member 285. That is, of the opposing front and back sides of the spacer member 285, the front side (mounting base 251 side) is an open surface, and the back side (side opposite the mounting base 251) is a closed surface. Alternatively, both the opposite front and back sides of the spacer member 285 may be closed surfaces or open surfaces. In addition, in order to make both the surfaces closed, a flat plate material is preferably attached later.

  The spacer member 285 is formed with a large number of lattice-shaped ribs 286, and the large number of ribs 286 prevents a relatively large one from being formed as a space-like lump. That is, the space is subdivided. Further, by providing a large number of ribs 286, it is possible to reduce the weight of the spacer member 285 while obtaining a desired effect such as subdivision of the space. In this case, since the spacer member 285 is formed of a transparent material, the discovery is easy even if a part of the rib 286 is cut off.

  On the front side (mounting base 251 side) of the spacer member 285, a notch groove 287 for avoiding interference with the projection 277 on the main controller 271 side when mounted on the mounting base 251 is provided. At this time, the projection 277 provided on the main controller 271 is provided at any one of the five predetermined positions, and the notch groove 287 is formed so as to correspond to the five predetermined positions. Five are provided. This notch groove 287 also serves as a guide groove when the spacer member 285 is slidably mounted along the back surface of the substrate mounting portion 252 of the mounting base 251. In addition, the spacer member 285 is formed with two rectangular cutout portions 288 in order to avoid interference with the locking tool 278 on the main control device 271 side when the spacer member 285 is mounted on the mounting base 251. In order to avoid interference with the seal screw storage part 258 provided on the mounting base 251, a rectangular cutout part 289 is formed in one place.

  In addition, a pair of left and right locking pieces 291 for locking and fixing the spacer member 285 to the mounting base 251 is formed on the front side (mounting base 251 side) of the spacer member 285, and the main control device 271. A pair of left and right locking pieces 292 for locking and fixing the spacer member 285 is formed. The locking piece 292 is provided at the center of the spacer member 285 so as to be sandwiched between the locking pieces 291.

  As described above, the front side of the spacer member 285 is basically a closed surface, but only a part corresponding to the locking piece 292 is opened (reference numeral 293).

  In addition, a coupling protrusion 295 is provided at the upper end of the spacer member 285. The coupling protrusion 295 corresponds to a sealing member for performing a sealing process between the spacer member 285 and the mounting base 251. That is, in a state where the spacer member 285 is mounted on the back side of the mounting base 251, the coupling protrusion 295 of the spacer member 285 and one of the coupled pieces 255 on the mounting base 251 are overlapped with each other in the front-rear direction. Then, a sealing process is performed between the spacer member 285 and the mounting base 251 by screwing a sealing screw into the coupling protrusion 295 and the coupled piece 255. As the sealing screw, a break screw or a one-way screw (one-way screw) is used. In this case, after the sealing process is performed, the sealing process cannot be canceled unless a predetermined destruction is performed. Therefore, if the sealing process is canceled illegally, the trace of the illegality remains.

  Here, as shown in FIGS. 15 and 16, the spacer member 285 is assembled on the back side of the board mounting portion 252 of the mounting base 251. At this time, the spacer member 285 is assembled to the mounting base 251 by sliding along the back surface of the board mounting portion 252, and at that time, the locking pieces 291 and 292 are locked and fixed to the mounting base 251 and the main controller 271. Is done. In the assembled state of the spacer member 285, the space behind the board mounting portion 252 of the mounting base 251 is filled with the spacer member 285. Therefore, there is no room for installing an illegal board or the like behind the board mounting portion 252 of the mounting base 251.

  Even assuming that the first control board unit 201 is mounted on the back surface of the pachinko machine 10, the space behind the board mounting portion 252 of the mounting base 251 is filled with the spacer member 285 as described above. It is possible to suppress the background space area from being misused for illegal purposes. Further, since the control board unit 201 is disposed adjacent to the variable display unit 35 as a picture display unit, the upper opening part of the opening part leading to the space behind the board mounting part 252 is formed by the variable display unit 35. The clogging of the spacer member 285 is also difficult. In other words, it is impossible to remove the spacer member 285 illegally or to remove a part of the spacer member 285.

  In addition, when utilizing the space area | region behind the mounting base 251 as an installation area | region of various objects and a board | substrate apparatus, it is also possible to implement | achieve, without installing the spacer member 285.

  Further, in a state where the first control board unit 201 is mounted on the back surface of the pachinko machine 10, the upper part of the control board unit 201 is covered with the back pack unit 203 as a cover member, and this also causes a hand behind the mounting base 251. It is becoming more difficult to insert tools and tools.

  As described above, the first control board unit 201 cannot be removed unless the back pack unit 203 is opened at a predetermined angle or larger, or the unit 203 is not removed. The back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation. That is, if the main body frame 12 cannot be opened, the first control board unit 201 cannot be rotated or removed as a result, and the main controller 271 cannot be removed. Therefore, unauthorized replacement or theft of the main controller 271 can be effectively prevented. Opening the main body frame 12 with respect to the outer frame 11 by properly operating the locking device is an opening condition for opening the back pack unit 203.

  Here, the arrangement of the main controller 271 and the sound lamp controller 272 will be described. The board mounting portion 252 for the main control device 271 and the board mounting portion 253 for the sound lamp control device 272 are configured by flat surfaces parallel to each other, and are orthogonal to the L shape when viewed from the back surface of the pachinko machine 10.

Each board mounting part 252 and 253 is formed. Moreover, these board | substrate mounting parts 252 and 253 are formed in the level | step difference shape seeing in the front-back direction.

  When the main control device 271 and the sound lamp control device 272 are mounted on each of the board mounting portions 252 and 253, the main control device 271 is disposed on the front side when viewed from the back of the pachinko machine 10, and the sound lamp control device 272 is located at the back. Placed on the side. In this case, since the board mounting portions 252 and 253 are formed with steps in the front-rear direction of the pachinko machine 10, each control is performed in a state in which the main controller 271 and the sound lamp control device 272 are mounted on the board mounting portions 252 and 253. The devices 271 and 272 are arranged such that a part thereof overlaps the front and rear. That is, as can be seen in FIG. 15 and the like, main controller 271 is arranged in a state where a part thereof (about 1/3 in the present embodiment) is floated. Therefore, it is possible to extend the sound lamp control device 272 to a region overlapping with the main control device 271, and, from another viewpoint, it is possible to extend the main control device 271 to a region overlapping with the sound lamp control device 272. Even within the limited size of the pachinko machine 10, it is possible to satisfactorily cope with the increase in size of the control devices 271 and 272, and the control devices 271 and 272 can be installed efficiently. In this case, the step between the board mounting portions 252 and 253 is made larger than the height dimension of the sound lamp control device 272. Therefore, even if the control devices 271 and 272 are three-dimensionally arranged, there is no inconvenience that interference occurs in the height direction. Further, in a state where the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting portion 252, and the variable winning device 32 and its electric wiring can be installed without difficulty.

  Since the spacer member 285 is arranged in the space area behind the mounting base 251 in the first control board unit 201 so as to fill the space area (because the space area is limited), it is simply an opening of the space area. Unlike an existing configuration or the like that shields a part, the space area itself can be reduced or eliminated, and installation of an illegal substrate or the like using the space area can be suppressed. Furthermore, since the spacer member 285 is configured to be coupled to the mounting base 251 and the main controller 271 by a sealing process, it is possible to sufficiently exert a deterrent against fraud. According to the above, it is possible to realize a configuration in which a control device or the like can be installed efficiently, and to take sufficient countermeasures against fraud in such a configuration.

  Of the openings that lead to the space behind the substrate mounting portion 252, one of the openings is closed by the variable display unit 35, so even if the openings that lead to the space behind the substrate mounting portion 252 are not completely closed by legs or the like, It is possible to prevent intrusion into the rear space and unauthorized manipulation of the spacer member 285.

  Since two board mounting portions 252 and 253 are formed in a stepped shape on the mounting base 251, the control devices (main control device 271 and audio lamp control device 272) that are to be arranged in two steps of height are both the same mounting base. 251 can be attached. In this case, when mounting a plurality of control devices on the pachinko machine 10, the arrangement form can be diversified.

  Since the two board mounting portions 252 and 253 are provided in a direction crossing each other, the main control device 271 and the sound lamp control device 272 can be arranged so as to cross vertically and horizontally. Therefore, it is possible to arrange a control device with a high degree of freedom.

  Since the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251 in a state where they overlap in the front-rear direction of the pachinko machine 10, a plurality of sizes can be efficiently used using a limited size on the back side of the pachinko machine 10. A control device can be arranged.

(Second Embodiment)
In the above embodiment, as the configuration of the first control board unit 201, the spacer member 285 is provided in the mounting base 251 so as to fill the space behind the board mounting portion 252 for the main board. To change. That is, the spacer member 601 is provided so as to fill the space behind the board mounting part 252 for the main board and the board mounting part 253 for the sound lamp board in the mounting base 251.

  The configuration of the first control board unit 201 in the present embodiment will be described with reference to FIGS. 28 and 29 are perspective views of the unit 201, and FIGS. 30 and 31 are exploded perspective views of the unit 201. However, since the configuration other than the spacer member 601 is generally unchanged, the configuration of the spacer member 601 will be described in detail.

  The spacer member 601 as a whole has substantially the same L shape as the mounting base 251, and the front side (mounting base 251 side) of the opposing front and back sides is an open surface, whereas the back side ( The side opposite to the mounting base 251 is a closed surface. The area of the front side surface of the spacer member 601 substantially matches the area of the two board mounting portions 252 and 253 of the mounting base 251. Further, the thickness of the spacer member 601 is different between a portion corresponding to the substrate mounting portion 252 for the main substrate and a portion corresponding to the substrate mounting portion 253 for the sound lamp substrate, and the former has a thickness dimension. Is a big one. In any case, however, the length is substantially the same as the length of the leg of the mounting base 251 or slightly shorter than the length of the leg of the mounting base 251. Therefore, the spacer member 601 has almost the same occupied volume as the back space of the board mounting portions 252 and 253 of the mounting base 251, and is just fit in the back space.

  However, it is also possible to reverse the open surface and the closed surface of the opposing front and back sides of the spacer member 601. That is, of the opposing front and back sides of the spacer member 601, the front side (mounting base 251 side) is a closed surface, and the back side (side opposite the mounting base 251) is an open surface. Alternatively, both the opposite front and back sides of the spacer member 601 may be a closed surface or an open surface. In addition, in order to make both the surfaces closed, a flat plate material is preferably attached later.

  A large number of lattice-like ribs 602 are formed on the spacer member 601, and the large number of ribs 602 prevents a relatively large one from being formed as a space-like lump. That is, the space is subdivided. Further, by providing a large number of ribs 602, the weight of the spacer member 601 can be reduced while obtaining a desired effect such as space subdivision.

  In addition, the spacer member 601 is formed with two rectangular cutout portions 603 to avoid interference with the locking device 278 on the main controller 271 side when the spacer member 601 is mounted on the mounting base 251, and A rectangular cutout 604 is formed at one location in order to avoid interference with the sealed screw storage 258 provided on the table 251.

  A pair of left and right locking pieces 606 for locking and fixing the spacer member 601 to the main controller 271 is formed on the front side (mounting base 251 side) of the spacer member 601. In addition, a coupling protrusion 607 is provided on the upper end portion of the spacer member 601. The coupling protrusion 607 corresponds to a sealing member for performing a sealing process between the spacer member 601 and the mounting base 251.

  That is, in a state where the spacer member 601 is mounted on the back side of the mounting base 251, the coupling protrusion 607 of the spacer member 601 and one of the coupled pieces 255 on the mounting base 251 are overlapped in the front-rear direction. Then, a sealing process is performed between the spacer member 601 and the mounting base 251 by screwing a sealing screw into the coupling protrusion 607 and the coupled piece 255. As the sealing screw, a break screw or a one-way screw (one-way screw) is used. In this case, after the sealing process is performed, the sealing process cannot be canceled unless a predetermined destruction is performed. Therefore, if the sealing process is canceled illegally, the trace of the illegality remains.

  In addition, a wiring guide groove 611 for guiding various wirings and the like is formed on the back side of the spacer member 601 (opposite side of the mounting base 251). A cutout portion 612 for suppressing interference with a member on the game board 30 side is formed in a portion corresponding to the board mounting portion 253 for the sound lamp board in the spacer member 601.

  Here, as shown in FIGS. 28 and 29, the spacer member 601 is assembled on the back side of the board mounting portions 252 and 253 of the mounting base 251. At this time, the spacer member 601 is locked and fixed to the main controller 271 by the locking piece 606. In the assembled state of the spacer member 601, the space behind the board mounting portions 252 and 253 of the mounting base 251 is filled with the spacer member 601. Therefore, there is no room for installing an illegal board or the like behind the board mounting portions 252 and 253 of the mounting base 251.

  Even if it is assumed that the first control board unit 201 is mounted on the back surface of the pachinko machine 10, the space behind the board mounting portions 252 and 253 of the mounting base 251 is filled with the spacer member 601 as described above. It is possible to prevent the space area behind the table 251 from being misused for illegal purposes. Further, since the control board unit 201 is disposed adjacent to the variable display unit 35 as a picture display unit, the upper opening part of the opening part leading to the space behind the board mounting part 252 is formed by the variable display unit 35. The clogging of the spacer member 601 is also difficult. In other words, it is impossible to remove the spacer member 601 illegally or to remove a part of the spacer member 601.

  Also in the present embodiment, as described above, it is possible to realize a configuration in which a control device or the like can be efficiently installed, and to take sufficient countermeasures against improperness in such a configuration.

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

  (A) The spacer member provided in the space behind the mounting base 251 in the first control board unit 201 may be configured as shown in FIG. FIG. 32 shows a modification of the spacer member 285. In FIG. 32A, it is the same that a large number of ribs 286 are provided on the spacer member 285 in a lattice shape, but the installation area of the ribs 286 is limited to a part. Here, the rib 286 is provided only in the upper half region of the figure. In addition, the rib 286 may be configured to be limited to a specific region such as the lower half, the right half, and the left half.

  In FIG. 32B, the spacer member 285 is provided with a plurality of columnar bosses 621 in place of a large number of lattice-like ribs 286. Also in this configuration, a member that blocks the space behind the mounting base 251 can be provided as appropriate. As a result, it is possible to realize a configuration suitable for suppressing the installation of an unauthorized substrate.

  (B) The spacer member provided in the space behind the mounting base 251 in the first control board unit 201 can be configured by a plurality of pieces. Specifically, a plurality of pieces of spacer members may be arranged in the vertical direction, the horizontal direction, or the front-back direction. In this case, it is desirable that a joining process (sealing process) is performed between the plurality of pieces. It is preferable that a sealing screw or the like is used as the joining process, and the releasing process cannot be performed once the joining process is performed.

  (C) In the above embodiment, as the configuration of the first control board unit 201, the mounting base 251 is mounted on the back side of the game board 30, and the main controller 271 and the board mounting portions 252 and 253 of the mounting base 251 are installed. Although the sound lamp control device 272 is mounted, this configuration is changed. For example, a plurality of leg members are erected on the back side of the game board 30 as pedestal members. Then, the main controller 271 and the sound lamp controller 272 are mounted by the leg members in a state of being separated from the back side of the game board 30 (floating state). In such a configuration, a spacer member is arranged in a space region (a region behind the main control device 271) formed between the back surface portion of the game board 30 and the main control device 271 so as to fill the space region.

  (D) The spacer member may be a non-hollow lump (solid shape) other than the hollow block shape.

  (E) In the first control board unit 201, a seal seal or the like can be used as a coupling member for performing a coupling process between the mounting base 251 and the spacer member 285.

  (F) In the above embodiment, in the mounting base 251 of the first control board unit 201, the two board mounting portions 252 and 253 parallel to the back surface of the game board 30 are substantially L-shaped and provided with a step. Although provided, this configuration is changed. For example, at least one of the board mounting portions 252 and 253 is provided non-parallel to the back surface of the game board 30. The board mounting portions 252 and 253 are provided in a substantially T shape. In this case, for example, the board mounting portion 252 for the main control device 271 is connected to the midway position of the board mounting portion 253 for the sound lamp control device 272. In addition, the board mounting portions 252 and 253 can be provided in a substantially cross shape.

  In addition, the longitudinal directions of the board mounting portions 252 and 253 are the same, and they are arranged horizontally or vertically. Further, the steps of the board mounting portions 252 and 253 are eliminated, and the heights are substantially the same. However, in this case, in consideration of securing the space behind the board mounting portion 252 for the main control device 271, the board mounting portion 253 for the sound lamp control device 272 is also the back side of the game board 30, as with the board mounting portion 252. It is good to arrange | position so that it may space apart from. Furthermore, it is set as the structure which provides three or more board | substrate mounting parts. For example, when three substrate mounting portions are provided, each substrate mounting portion can be provided so as to be bent on three sides.

  (G) The control device mounted on the mounting base 251 together with the main control device 271 may be changed from the sound lamp control device 272 to another control device. Alternatively, another control device may be mounted on the mounting base 251 together with the main control device 271 in addition to the sound lamp control device 272. As another control device, a display control device for carrying out symbol display control can be considered.

  (H) The leg portion may be provided separately from the mounting base 251. For example, the plate unit is provided on the collective plate unit 215 attached to the back surface of the game board 30 so as to stand rearward, and this plate unit is used as a shielding unit.

  (I) In the above embodiment, in the mounting base 251 of the first control board unit 201, the upper opening of the openings leading to the space behind the board mounting part 252 for the main controller 271 is designated as the variable display unit 35. However, instead of the variable display unit 35, another component member provided adjacent to the first control board unit 201 (mounting base 251) may be used.

  (J) In the above embodiment, the first control board unit 201 (mounting base 251) is attached to the back surface of the game board 30, but this is changed and the first control board unit 201 is attached to the back surface of the gaming machine main body. It is good also as a structure attached to another member. For example, the first control board unit 201 (mounting base 251) is attached to the main body frame 12 constituting the gaming machine main body.

  (K) In the above embodiment, the control devices 271 and 272 having substantially the same height are mounted on the board mounting portions 252 and 253 on the mounting base 251 of the first control board unit 201, but this configuration is changed. For example, the heights of the control devices mounted on the board mounting portions 252 and 253 are different, a relatively tall control device is mounted on the lower side, and a relatively short control device is mounted on the upper side. It is good also as a structure to mount. In this case, it becomes possible to make the height (protrusion) of each control device to the rear of the pachinko machine 10 substantially equal. Therefore, a desirable layout of the control device or the like can be realized.

  (L) In the above embodiment, on the back side of the pachinko machine 10, various control devices are distributed and mounted on two control board units (first control board unit 201, second control board unit 202). The configuration can also be changed, and three or more control board units (that is, mounting bases) may be provided.

  (M) It is good also as a structure which attaches the base member for mounting | wearing members other than a control apparatus to the main body frame 12 or the game board 30. FIG. As a member other than the control device, a power supply device 313, an electric member such as a motor or a solenoid, a game ball passage member, and the like are conceivable.

  (N) Another type of ball game machine different from the above embodiment, for example, a game machine such as a pachinko machine, an arrange ball machine, a sparrow ball or the like having other objects, a game ball (pachinko instead of a medal) It can be applied to a ball-cylinder type game machine that uses a ball).

  In a ball-type spinning machine, a reel device (cylinder device) with a plurality of symbols on the outer periphery, devices such as a bet switch and start lever operated by the player, and taking in game balls A take-in device or the like is provided for counting the game balls that are allowed or forbidden and sequentially taken. In this case, the game balls stored in the ball tray are guided to the take-in device via the alignment passage portion and the take-in port. Then, in response to the player's operation of the bet switch, the take-in device takes in the game balls, and the start of each game (reel rotation accompanying the start lever operation) is allowed according to the number of game balls taken in. Is done.
