The substrate case is formed of a transparent synthetic resin material, and the inside of the dispensing control substrate can be visually recognized by the transparent substrate case. The board case is provided with a sealing portion f2 (so-called crimping portion) as sealing means for connecting the front and back case members constituting the case. The sealing part f2 enables the substrate case to be opened by breaking or the like, and since the member that has been broken remains as the opening history after opening, the opening history can be confirmed by the opening history. ing. Thereby, in the case where the substrate case is illegally opened, an illegal act can be found by checking the sealing part f2.

  In addition, the base plate 161 of the back cover member 151 to which the payout control device 153 is attached is provided with two fixtures 181 made of Nylatch (registered trademark) or the like on the substrate case of the payout control device 153. Are provided with two holes 182 at the top and bottom (see FIG. 9). In this case, by placing the payout control device 153 at a predetermined mounting position and setting the fixture 181 in a fixed state with respect to the attached hole portion 182, the mounting of the payout control device 153 to the back cover member 151 is completed. A grounding metal plate 183 is attached to the base portion 161 of the back cover member 151.

(Description of power supply device 154)
Next, the power supply device 154 will be described. The power supply device 154 includes a power supply board for generating a power supply voltage, and further includes a setting key switch for a hall manager or the like to variably set a payout rate. The gaming machine 10 according to the present embodiment. Since the setting key switch has a characteristic feature, the power supply device 154 will be described in detail below. 10, (a) is a side view of the power supply device 154, (b) is a front view of the power supply device 154, and (c) is a rear view of the power supply device 154. 11 and 12 are exploded perspective views of the power supply device 154, and FIG. 13 is an exploded perspective view of the setting key switch 240.

  The power supply device 154 includes a power supply board 201 on which various electrical components for generating a power supply voltage are mounted. The power supply board 201 is accommodated in a board case 202 including a pair of front and back case bodies 203 and 204. . Although various electrical components are not shown, the substrate surface visible in FIG. 11 is the electrical component mounting surface. A case body 203 covering the electric component mounting surface side (front surface side) of the power supply substrate 201 is a front case body, and a case body 204 covering the opposite side (back surface side) is a back case body. The case bodies 203 and 204 are both formed of a transparent synthetic resin material, and the power supply substrate 201 inside the case bodies 203 and 204 can be visually recognized even in a state of being accommodated in the substrate case 202.

  As shown in FIG. 11, on the electric component mounting surface side (front surface side) of the power supply board 201, a power switch 205 for starting the gaming machine 10 and a reset for resetting various states of the gaming machine 10 A switch 206 and the like are provided. In addition, various power components such as resistors and capacitors for configuring a power circuit are mounted on the power substrate 201, and signal line patterns, ground patterns, and the like are appropriately formed. Omitted.

  This gaming machine 10 has a backup function for various data, and maintains the state at the time of power failure even in the event of a power failure, and returns to the state at the time of power failure upon recovery from power failure (recovery) It can be done. In this case, for example, when the power supply is shut down in the normal procedure, such as when the game hall is closed, the state before shutting down is stored and retained, but if the power switch 205 is turned on while pressing the reset switch 206, the backup data is reset. It has come to be. If the reset switch 206 is pressed while the power switch 205 is on, the error state is reset.

  The pair of front and back case bodies 203 and 204 have substantially the same shape as the power supply substrate 201 in plan view, and the respective joint portions provided at the peripheral portions of the case bodies 203 and 204 are joined together. The entire power supply substrate 201 is accommodated in the substrate case 202. Openings 208 and 209 are formed in the front case body 203 in accordance with the positions of the power switch 205 and the reset switch 206. When the power supply substrate 201 is accommodated in the substrate case 202, the openings 208 and 209 are formed. Thus, a part of the power switch 205 and the reset switch 206 appears on the front side of the substrate case 202.

  In addition, the front case body 203 is formed with openings 211 for allowing connector parts (not shown) provided on the power supply board 201 to appear on the front side of the board case 202 at a plurality of locations, and for heat dissipation. A large number of small holes 212 are formed.

  Further, the case member 203 and 204 are coupled to the substrate case 202 in an unopenable state, and a seal coupling part (so-called caulking part) for leaving a trace of the coupling release when the coupling is temporarily released. Is provided. Specifically, cylindrical coupling protrusions 221 and 222 are formed on the front case body 203 and the back case body 204 so as to protrude inward. These coupling protrusions 221 and 222 are provided at two places on each case body 203 and 204, and in a state where both case bodies 203 and 204 are joined, the leading ends of the coupling protrusions 221 and 222 face each other. Holes 221a and 222a formed at the center of the coupling protrusions 221 and 222 are configured to be aligned on the same axis. The hole 221a (hole on the front case body 203 side) of the coupling protrusion 221 is a bottomed hole opened only to the back case body 204 side, whereas the hole 222a ( The hole on the back case body 204 side) is a through hole penetrating in the axial direction. The power supply board 201 is formed with a circular hole 223 having a larger hole diameter than the coupling protrusion 222 provided on the back case body 204. When the power supply board 201 is assembled to the board case 202, the hole 223 is formed. Thus, the interference between the power supply substrate 201 and the coupling protrusions 221 and 222 is avoided.

  In the above configuration, the power supply substrate 201 and both case bodies 203 and 204 are integrated, and a sealing screw is screwed into the hole of each coupling protrusion 221 and 222 from the back case body 204 side. , 204 is subjected to a seal coupling process (caulking process). At this time, the holes 221a and 222a of the case bodies 203 and 204 have a smaller diameter than the screw portion of the sealing screw, and when the sealing screw is screwed, the screw is tightened while being screwed by the sealing screw. Is done.

  Although a detailed description by 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 driver. When the screw head is broken at the time of sealing 204, the screw loosening operation by a driver or the like becomes impossible thereafter. In this case, in order to release the seals of the two case bodies 203 and 204, a plurality of (four in the illustrated configuration) connecting portions provided around the coupling protrusion 222 on the back case body 204 side must be broken. However, 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.

  A setting key switch 240 is attached to the outer surface of the back case body 204. The setting key switch 240 sets the play rate (including the winning probability) of the gaming machine 10 to one of six predetermined levels (“Setting 1” to “Setting 6”), so-called setting change time This is a setting validation device for validating the setting operation of the game machine 10, and the setting change of the gaming machine 10 is made effective by performing a predetermined setting operation in a state where the setting change is validated by the setting key switch 240. Done. After the setting is changed, the payout game balls are adjusted by using the probability lottery data of the combination of symbols related to winning and operation corresponding to each stage.

  As described above, the power supply device 154 is provided with the power switch 205 and the reset switch 206. The power switch 205 and the reset switch 206 can be operated from the front side of the power supply device 154. The switch 240 can be operated from the back side of the power supply device 154 (that is, the side opposite to the power switch 205 and the reset switch 206).

  As a configuration relating to the setting key switch 240, an installation step 231 is formed on the back case body 204 so as to protrude in a step shape on the back side of the substrate case, and the setting key switch 240 is installed on the installation step 231. It has come to be. The installation step portion 231 has openings 232 communicating with the inside and outside of the case, and screw holes 233 are formed at two locations around the opening 232. In addition, substrate sandwiching portions 234 for sandwiching a substrate 244 described later are formed at two places in the upper and lower parts of the drawing so as to sandwich the opening 232. The substrate holding portion 234 is formed with a substantially V-shaped guide groove for guiding the substrate 244.

  As shown in FIG. 13, the setting key switch 240 includes a switch body 241 and a key switch cover 242. In this case, in the switch body 241, the key cylinder 245 is mounted on the substrate 244, and the key insertion port 245a is provided at the tip of the key cylinder 245. Similarly, connector terminals 246 are provided on the substrate 244. The key switch cover 242 includes a peripheral wall portion 242a and a top plate portion 242b that surround four sides, and a window portion 247 is formed by cutting out a part of the peripheral wall portion 242a and the top plate portion 242b. In a state where the switch body 241 is attached to the key switch cover 242, the tip end portion (key insertion port 245 a) of the key cylinder 245 appears from the window portion 247. In addition, inside the key switch cover 242, substrate holding portions 248 for holding the substrate 244 are formed at two locations, upper and lower. The substrate holding portion 248 has a substantially V-shaped guide groove for guiding the substrate 244. In addition, a screw hole 249 is formed in the key switch cover 242 at a position corresponding to the screw hole 233 on the back case body 204 side.

  Then, the switch body 241 is attached to the key switch cover 242 so that one end side of the board 244 is fitted into the board holding portion 248 of the key switch cover 242 (the state shown in FIG. 11), and the setting key switch 240 is installed in this state. It is installed on the installation step 231 of the back case body 204. Further, after the installation, screws (not shown) are screwed into the screw holes 233 and 249 from the inner surface side of the back case body 204 so that the setting key switch 240 cannot be separated from the back case body 204. At this time, the other end side of the substrate 244 is fixed by the substrate holding portion 234 on the back case body 204 side.

  With the setting key switch 240 attached to the back case body 204 as described above, the power supply substrate 201 and the front case body 203 are integrated with the back case body 204. In this case, since the screw for fixing the setting key switch 240 is screwed from the inside of the back case body 204, the screw cannot be removed from the outside of the board case, and the setting key switch 240 cannot be removed. It has become. As described above, the substrate case 202 is subjected to a seal coupling process, and the setting key switch 240 is more difficult to remove by performing this seal coupling process.

  Here, in particular, the setting key switch 240 is provided such that the axial direction of the key cylinder 245 substantially coincides with the substrate plane direction of the power supply substrate 201, whereby the key insertion slot 245 a is arranged in the substrate plane direction of the power supply substrate 201. It is designed to face the same direction. Speaking of the relationship between the power supply board 201 and the board 244 of the setting key switch 240, they are almost vertical. However, in detail, as shown in FIG. 14 (schematic view of the power supply device 154 as viewed from above), the axial direction J1 of the key cylinder 245 is set so as to slightly deviate from the substrate plane direction J2 of the power supply substrate 201. Has been. Therefore, the key insertion slot 245a of the key cylinder 245 is in the same direction as the board plane direction of the power supply board 201 and slightly rearward.

  As shown in FIG. 10B, when the power supply device 154 is viewed from the front, the setting key switch 240 is completely hidden behind the board case 202. As a result, when the setting key switch 240 is mounted on the back side of the gaming machine, it is difficult to cheat the setting key switch 240 from behind the gaming machine.

  The connector terminal 246 provided on the board 244 of the setting key switch 240 is configured to be electrically connected to the connector terminal 251 on the power board 201 via a harness (not shown). In this case, a notch hole 252 for guiding a harness extending from the setting key switch 240 (that is, the back surface side of the power supply board 201) to the front surface side of the power supply board 201 is formed near the connector terminal 251 in the power supply board 201. The back case body 204 is formed with guide ribs 253 for guiding the harness led out from the opening 232 to the vicinity of the notch hole 252 of the power supply substrate 201.

  Therefore, a harness (not shown) extending from the connector terminal 246 of the setting key switch 240 is guided to a gap region between the back case body 204 and the power supply board 201 through the opening 232 of the back case body 204, and further guide ribs 253. Is guided to the vicinity of the notch hole 252 of the power supply substrate 201. The harness is led out to the front surface side (electrical component mounting surface side) of the power supply board 201 through the notch hole 252 and the distal end portion thereof is connected to the connector terminal 251 on the power supply board 201. . In the above configuration, the harness is guided by a prescribed route, and inconveniences such as damage due to interference with other members on the back surface side of the power supply substrate 201 are suppressed.

  In short, a pin-shaped terminal such as an electrical component mounted on the front surface side protrudes from the back surface side of the power supply substrate 201, and it is conceivable that the harness is damaged by contacting the tip of the pin-shaped terminal. In this regard, as described above, the harness is guided by the guide rib 253 along the restriction route, so that the harness does not come into contact with the pin-like terminal, and as a result, damage to the harness is suppressed.

  Further, the front case body 203 is formed with a prismatic enclosure 255 so as to protrude inward (see FIG. 12). The enclosure portion 255 is a connector enclosure member that extends from the surface portion of the front case body 203 to the power supply board 201, and the connector terminal 251 and the notch hole 252 on the power supply board 201 are enclosed by the enclosure portion 255. In this case, since the connector terminal 251 and the cutout hole 252 on the power supply board 201 are surrounded by the enclosing portion 255, an illegal act on the connector terminal 251 from the front side of the power supply device is suppressed. That is, an illegal act such as connecting an unauthorized device to the connector terminal 251 cannot be performed.

  In addition, attachment holes 261 are provided at a plurality of locations (five locations in the present embodiment) on the peripheral edge of the substrate case 202. In addition, a plurality of support columns 262 are provided at positions corresponding to the mounting holes 261 on the substrate case 202 side on the base portion 161 (here, a portion below the protective cover portion 162) of the back cover member 151. Accordingly, with the power supply device 154 placed on the support column 262, a screw or the like is screwed into each mounting hole 261 from the back side of the gaming machine 10, so that the power supply device 154 is attached to the base portion 161 of the back cover member 151. It is supposed to be fixed.

  Further, as shown in FIG. 7, the base portion 161 of the back cover member 151 is connected to the back cover member 151 at the tip end portion (key insertion port 245a) of the key cylinder 245 with the power supply device 154 mounted on the base portion 161. An opening window portion 265 is formed to be exposed inside. The opening window 265 has a size sufficient to expose the key cylinder 245 to the inside of the back cover member 151, and is formed sideways by using a stepped portion formed in the base portion 161. . More specifically, the key switch is set using a space area between the protective cover 162 (the storage area of the reel device 82) and the game ball path components (the payout ball path section 172 and the discharge ball path section 174). 240 is installed. In particular, the setting key switch 240 is provided at a position where it does not overlap with the game ball passage components (the payout ball passage 172 and the discharge ball passage 174).

  In this case, in a state where the power supply device 154 is mounted on the back cover member 151, the key insertion slot 245a of the setting key switch 240 is not visible from the rear of the gaming machine, and the setting change key is inserted into the key insertion slot 245a. Can not be.

  In the gaming machine 10, the key insertion slot 245 a of the setting key switch 240 is not exposed unless the locking device 60 is unlocked and the blocks 13 to 15 are separated and opened. That is, the setting change key can be inserted into the key insertion slot 245a only when the blocks 13 to 15 are separated and opened. Therefore, it is difficult to perform unauthorized setting changes. However, when the blocks 13 to 15 are separated and opened, the key insertion slot 245a faces the open side. Therefore, when the setting is properly changed, the setting change key can be easily inserted into the key insertion slot 245a.

  The power supply device 154 is basically screw-fixed from the back side of the gaming machine using the mounting hole 261. However, since the screw fixing is performed from the back side of the gaming machine, the removal is relatively easy. When removed, the power supply device 154 is removed from the back cover member 151. In this case, even if the key insertion port 245a of the setting key switch 240 is exposed inside the back cover member 151 as a countermeasure against fraud as described above, the countermeasure against the fraud may be ineffective.

  Therefore, in this gaming machine 10, the positions of the key switch cover 242 of the setting key switch 240 and the base portion 161 of the back cover member 151 are matched with each other when the power supply device 154 is mounted on the back cover member 151. Screw holes 266 and 267 are provided (see FIGS. 7 and 10). Then, with the power supply device 154 mounted on the back cover member 151, a screw is screwed into the screw small holes 266, 267 from the inside of the back cover member 151 (that is, the front side in the state shown in FIG. 7). Thus, the power supply device 154 is not removed from the back cover member 151 simply by removing the screw from the back side of the gaming machine. Therefore, unauthorized removal of the power supply device 154 can be suppressed. Further, the anti-tampering method in which the key insertion port 245a of the setting key switch 240 is exposed to the inside of the back cover member 151 as described above can be made to function more reliably.

  In the game hall, the setting is changed by the hall manager or the like according to the following procedure. At this time, when changing the setting, the gaming machine main part 12 (door block 13, surface change) with respect to the outer frame 11 in accordance with the unlocking operation of the locking device 60 (for example, the clockwise rotation operation of the unlocking key). The block 14 and the payout block 15) are separated and opened, and the payout block 15 with respect to the surface changing block 14 in response to another unlocking operation (for example, a counterclockwise turning operation of the unlocking key). Is released. In this state, a setting change key is inserted into the key cylinder 245 (key insertion port 245a) of the setting key switch 240, and a predetermined setting changing operation is performed.

  First, the power switch 205 is turned off, the setting change key inserted into the key cylinder 245 (key insertion slot 245a) is turned 90 degrees clockwise, and then the power switch 205 is turned on. As a result, the current set value is displayed on the count display LED provided in the payout control device 153 and the like, and six-stage setting changes are possible. Thereafter, each time the reset switch 206 is pressed, the setting value display changes as 1 → 2 → 3 →... (The maximum value is 6 and then returns to 1), and the setting is selected by the operation. When the start lever 33 is operated after selecting the setting, the set value is fixed. Thereafter, when the setting change key is turned 90 degrees counterclockwise to return the setting key switch 240 to the original state, the setting operation is completed.

  When the setting change key is turned 90 degrees in the clockwise direction with the power switch 205 turned on, the current setting value is displayed on the count display LED.

  In addition, in the base portion 161 of the back cover member 151, a ball rental unit connection board 271 that manages payout of game balls lent out from the ball rental unit is provided on the side of the power supply device 154.

(Explanation of electrical configuration)
Next, the electrical configuration of the gaming machine 10 will be described based on the block diagram of FIG. In FIG. 15, each electrical component is divided into a door block 13, a surface changing block 14, and a payout block 15. In addition, a supply line of power supplied from the power supply device 154 is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  In FIG. 15, the main control device 84, the display control device 85, and the payout control device 153 are all configured by a logical operation device having a CPU, a ROM, a RAM, etc., and the CPU of each control device is a ROM. Various controls relating to the game are executed based on a calculation program stored in advance. Each of these control devices is connected via a signal line, a relay board, and the like, and in the game, the game progresses by exchanging commands and the like between the control devices.

  Specifically, in the surface changing block 14, the reel device 82 and the external terminal board 302 are connected to the main control device 84 via the reel relay substrate 301, and the display control device 85 is connected via the sub relay substrate 303. It is connected. In the reel device 82, the rotation of each of the reels 101 to 103 is controlled based on a command from the main control device 84. The external terminal board 302 is a relay device connected to a hall management device (so-called hall computer) installed in a game hall or the like. Output to the management device. The display control device 85 inputs various commands related to the auxiliary effects of each game from the main control device 84, and performs the auxiliary effects by the liquid crystal display device 83 according to the commands, and the door upper relay board provided in the door block 13 The driving of speakers and lamps is controlled via 306.

  Although description by illustration etc. was abbreviate | omitted, this game machine 10 is provided with the door switch for detecting that the game machine main part 12 (door block 13) was open | released with respect to the outer frame 11, The door switch detection signal is input to the main controller 84 via the reel relay board 301.

  In the main controller 84, a part of RAM is provided with a backup area in which a backup voltage is supplied from the power unit 154 and data can be retained (backup) even after the gaming machine 10 is powered off. ing. Therefore, when the power supply is shut down due to the occurrence of a power failure or the like, various data at the time of power shutdown is stored and retained in the RAM backup area, and the gaming machine 10 is turned on at the next power-on (including power-on due to power failure cancellation). Can be restored to the state before the power was shut off.

  In addition, the payout block 15 is provided with a payout block relay board 305, through which the main control device 84 of the surface changing block 14 and the payout control device 153 of the payout block 15 are connected. Insertion unit 65 is electrically connected. In addition, the main controller 84 of the surface changing block 14 and the door block relay board 307 of the door block 13 are electrically connected via the payout block relay board 305.

  In this case, when various operation members (the bet switch 38, the start lever 33, and the stop switches 35 to 37) of the door block 13 are operated by the player, the operation is detected by the operation detection unit built in these operation members. Each operation detection signal is input to the main controller 84 via the door block relay board 307 and the payout block relay board 305. For example, when an operation detection signal associated with the operation of the bet switch 38 is input to the main control device 84, the main control device 84 outputs an acquisition control signal to the acquisition unit 65 via the payout block relay board 305. The take-in unit 65 drives the solenoid by this take-in control signal, and the game balls are taken in sequentially. The detection signal of the game ball take-in detection sensor at the time of taking in the game ball is also input to the main controller 84 via the payout block relay board 305.

  In addition, a stop symbol (three upper and lower symbols visible from the viewing window 23 of the door block 13 and a combination of the symbols) of each reel of the reel device 82 is a predetermined game ball payout combination (small role symbol, bonus symbol). If it matches, the main control device 84 sets the number of game balls to be paid out according to each winning combination, and sends out a payout control signal corresponding to the payout number via the payout block relay board 305. To 153. As a result, the payout control device 153 drives the payout device 168 (payout motor) to pay out the game ball.

  In the payout control device 153, as in the RAM of the main control device 84, a backup voltage is supplied from the power supply device 154 even after the power of the gaming machine 10 is cut off, as in the RAM of the main control device 84 (backup). There is a backup area that can be used. Therefore, when the power supply is shut down due to the occurrence of a power failure or the like, various data at the time of power shutdown is stored and retained in the RAM backup area, and the gaming machine 10 is turned on at the next power-on (including power-on due to power failure cancellation). Can be restored to the state before the power was shut off.

  The power supply device 154 takes in AC 24 volt power supplied from the outside, generates + 12V power for driving various switches and motors, + 5V power for logic, backup power for RAM backup, etc. + 5V power and backup power are supplied to the main controller 84, the payout controller 153, and the like.

(Simple explanation of the game)
Next, an outline of the game performed by the player for the gaming machine 10 having the above configuration will be briefly described.

  At the start of the game, when the player presses the bet switch 38 in a situation where there are enough game balls on the upper plate 41, the take-in unit 65 takes in the game balls. When the start lever 33 is operated after a predetermined number (for example, 15) of game balls corresponding to the number of bets has been taken in, the reels 101 to 103 of the reel device 82 are simultaneously or in a predetermined order. Start spinning. When the start lever 33 is operated, the main control device 84 performs an internal lottery regarding small roles, replays, bonus games, and the like. When the reels 101 to 103 rotate, the symbols attached to the outer peripheral surface thereof are visually recognized in such a manner that they move from top to bottom through the viewing window 23.

  Thereafter, when the player operates the stop switches 35 to 37 in an arbitrary order, the rotation of the corresponding reels 101 to 103 is stopped in accordance with the operation timing of each of the stop switches 35 to 37. At this time, when each of the reels 101 to 103 is stopped, pull-in stop control for stopping a predetermined symbol at a specific position is appropriately performed. For example, when a small combination is established by an internal lottery, the stop symbols can be slid up to 4 symbols from the operation timing of the stop switches 35 to 37 so that the combination of the stop symbols in which the small combination is established (Stop symbol sliding is performed). Incidentally, after the start of the rotation of each of the reels 101 to 103, when the specified time elapses without the stop switches 35 to 37 being operated, the rotation of each of the reels 101 to 103 is stopped at the elapse of the specified time.

  When the reels 101 to 103 are stopped (when the symbols are stopped), if the stopped symbols and the combinations thereof match the small role symbol or the bonus symbol, the number of game balls corresponding to the winning combination at that time is paid out. In this case, the game ball is paid out to the upper plate 41 by driving the payout device 168.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  In the power supply device 154 provided integrally with the setting key switch 240, the setting key switch 240 is arranged on the side opposite to the electrical component mounting surface, and the key insertion slot 245a faces in the lateral direction with respect to the front direction of the gaming machine. Thus, the setting key switch 240 can be hidden from the rear of the gaming machine. In addition, it is possible to make it difficult to insert a setting change key into the key insertion slot 245a from the back of the gaming machine and perform setting changes illegally. Therefore, the deterrence against an illegal setting change act can be exhibited.

  In particular, the gaming machine 10 is installed in an island facility (pachinko island) in a game hall, and is released from the island facility by being rotated to the near side. Further, the rear side of the gaming machine is opened, and the power supply device 154 and the like are exposed. Therefore, for example, if one gaming machine 10 that is opposite to the back is rotated from the island facility, the back of the other gaming machine 10 becomes fully visible, and there is a concern that an illegal setting change action or the like may occur. Fraud countermeasures can be taken.

  Similarly, in power supply device 154, reset switch 206 for performing a setting change operation and setting key switch 240 for enabling the setting change operation are provided on both sides of power supply board 201, respectively. It becomes impossible to perform the setting validation operation by the above and the setting change operation by the reset switch 206 all at once. Therefore, further anti-fraud measures can be taken.

  Since the setting key switch 240 is installed so that the key insertion slot 245a is exposed only when the payout block 15 is separated and opened with respect to the surface changing block 14, even if the fraudulent person tries to change the setting illegally, it is unnecessary. Time and effort (separately opening each of the blocks 14 and 15) is required, so that the deterrence of fraud can be applied.

  Further, since the unlocking operation of the locking device 60 is indispensable in order to separate and open the payout block 15 with respect to the surface changing block 14, the key insertion slot 245a is exposed or the key insertion slot 245a is played. It is possible to strictly manage the concealment inside the machine and realize more reliable fraud countermeasures.

  The payout block 15 is provided with an opening window portion 265 communicating with the longitudinal direction of the gaming machine, and the key insertion port 245a is exposed to the front side of the payout block 15 through the opening window portion 265. Therefore, the payout block 15 must be opened. Thus, the setting change key cannot be inserted into the key insertion slot 245a, and it is possible to make it more difficult to perform an illegal setting change act.

  Since the setting key switch 240 is installed using the space area between the housing part of the reel device 82 and the path component parts of the game balls (the payout ball path part 172 and the discharge ball path part 174), efficient space use is possible. realizable.

  Further, in the gaming machine 10, components having uniqueness for each model, such as the reel device 82, the liquid crystal display device 83, the main control device 84, and the display control device 85, are collectively mounted on the surface changing block 14. Therefore, these devices can be exchanged together as a group. That is, at the time of model replacement in a game hall or the like, the main model replacement work is completed by exchanging the surface changing block 14. Therefore, it is possible to easily change the model of the gaming machine 10. In addition, since parts other than the replacement block 14 can be reused, it is possible to reduce resource consumption.

  In addition to the embodiment described above, for example, the following may be implemented.

  (A) In the above embodiment, in the power supply device 154, the setting key switch 240 is installed so that the key insertion slot 245a faces in the lateral direction with respect to the front direction of the gaming machine. The setting key switch 240 may be installed so that 245a faces upward or downward.

  (B) In the above embodiment, the configuration change key can be inserted into the key insertion slot 245a only when the payout block 15 is separated and opened with respect to the surface change block 14. The configuration may be such that the setting change key can be inserted into the key insertion slot 245a without separating and releasing the payout block 15 from the replacement block 14. However, in this case as well, the setting key switch 240 is installed on the opposite side of the electrical component mounting surface and the key insertion slot 245a faces the front direction of the gaming machine in the same manner as described above, or the setting is changed. A reset switch 206 for performing an operation and a setting key switch 240 for enabling the setting change operation are provided on both sides of the power supply board 201, respectively. Thereby, the deterrent with respect to an unauthorized setting change act can be exhibited.

  (C) In the above embodiment, in the power supply device 154, the substrate case 202 for housing the power supply substrate 201 and the key switch cover 242 of the setting key switch 240 are molded separately, and they are joined together. However, it is also possible to change the circuit board case 202 and the key switch cover 242 so as to be integrally formed.

  (D) In the above embodiment, the setting key switch 240 is integrally provided in the power supply device 154, but this is changed to another board device such as the main control device 84, the display control device 85, and the payout control device 153. The setting key switch 240 may be integrally provided. Alternatively, the setting key switch 240 may be provided integrally with other components of the gaming machine 10 in addition to the setting key switch 240 provided integrally with the board device.

  (E) In the above-described embodiment, the reel device 82 and the liquid crystal display device 83 are used as gaming devices to be mounted on the surface changing block 14, and these devices are arranged side by side, but this is changed. For example, the reel device 82 and the liquid crystal display device 83 are provided side by side. Further, only a single reel device may be mounted, or a plurality of reel devices may be mounted. In addition, the liquid crystal display device that functions as an auxiliary effect device can be changed to another electrical display device such as a dot matrix, LED, electroluminescence (EL), or a fluorescent display tube.

  (F) It is good also as a structure which can divide | segment the door block 13 as a door member into two upper and lower members. For example, the lower door member including the operation unit 30 is defined as a lower door member, and the upper door member is defined as an upper door member.

  (G) In the gaming machine 10, the lower tray 51 is eliminated and only the upper tray 41 is provided. In this case, a large amount of game balls can be stored and held as the gaming machine 10 by increasing the capacity of the upper plate 41 and the payout passage behind it.

  (H) The arrangement of the operation means represented by the start lever 33 and the stop switches 35 to 37 in the above embodiment is merely an example. For example, the start lever 33 may be arranged on the right side, or may be changed as appropriate, such as a button instead of the lever.

  (I) The ball-use type spinning machine 10 in the above-described embodiment does not necessarily have to be installed on Pachinko Island. In this case, the outer frame may not be a requirement, and the gaming machine main part 12 may be supported by a housing or the like. Further, the game ball as a game medium is not limited to a pachinko ball, and may be a metal ball other than a pachinko standard. Other than the metal sphere, for example, a ceramic sphere may be used.

  (J) The present invention can also be embodied in a gaming machine other than a ball-use spinning machine (parrot). For example, the characteristic configuration of the power supply device 154 is applied to a slot machine using game medals as game media. In general, a slot machine has a setting change function. By applying the present invention, an illegal setting change action is suppressed. In the case of a slot machine, it has a housing and a front door on the front side thereof, and the front surface is opened by the front door. A setting change switch (reset switch) is installed on the front side of the board device (power supply device, etc.) so that it can be seen from the front of the gaming machine when the front is opened, and a setting validation device (setting key switch) is installed on the back side of the board device To do. At this time, as described above, it is preferable to install the setting validation device so that the key insertion portion faces in the lateral direction with respect to the front direction of the gaming machine. In this case, the substrate device is provided with a rotation mechanism such as a hinge, and the setting change key is inserted into the key insertion portion in a state where the substrate device is rotated to the front side, thereby enabling the setting change.

  Further, even in a pachinko machine, it is considered that a desired effect can be obtained by applying the present invention as long as it has a setting change function.
