FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the above drawings. [First embodiment] First, the slot machine according to the first embodiment will be described with reference to Figures 1 to 4. In the following, when describing the basic configuration of the slot machine with reference to Figures 1 to 3, the directions of the arrows shown in Figure 2 are defined as the up-down direction, the front-rear direction, and the left-right direction, respectively.

[0010] <External configuration of slot machine> 1 to 3, the slot machine 1 according to this embodiment includes a box-shaped housing 5 (main body member) with an open front (forward) and a front door 2 attached so as to be openable and closable to the front opening of the housing 5. The front door 2 is attached so as to be openable and closable to the side relative to the front opening of the housing 5 by using hinge mechanisms 6a to 6c disposed in front of the left side plate 5a of the housing 5 when viewed from the front.

[0011] As shown in Figs. 1 and 2, an upper panel assembly 10, a middle panel assembly 20, a lower panel assembly 30, and a tray assembly 40 are attached to the front surface of the front door 2 in this order from the top. In the center of the upper panel assembly 10, a display screen 11a of a liquid crystal display device 11 arranged on the back side thereof is arranged to face the front, and a first performance lamp 12 and second performance lamps 13a, 13b are arranged around it. In addition, a pair of upper speakers 15a, 15b are arranged on the left and right of the front lower side of the display screen 11a, and a decorative member 16 with a predetermined decoration is arranged in the center of the front lower side of the display screen 11a.

[0012] The central panel CPL located at the center of the middle panel assembly 20 is provided with a reel window W through which the surfaces of the left reel 3a, the middle reel 3b, and the right reel 3c arranged side by side in the cabinet 5 are visible. On the upper surface side of the operation panel 21 provided below the reel window W, there are attached a medal insertion port 22 for inserting game medals (game media), a BET switch unit 23 for betting game medals within a credited range, and a performance switch unit 24 for performing operations related to performance. On the front side of the operation panel 21, there are attached a start lever (start switch) 25 operated when starting the rotation of all the reels 3a to 3c, three stop switches 26a, 26b, and 26c for individually stopping the rotation of each of the reels 3a, 3b, and 3c, a reject switch 27 for returning game medals inserted from the medal insertion port 22 and remaining therein, and a settlement switch 28 for returning credited game medals to a game medal storage tray 42 described later. In addition, in the case of a so-called smart gaming machine in which an IC card storing information corresponding to the number of gaming medals (hereinafter referred to as "game medal information") is inserted into a dedicated unit as a medium for playing a game, as in the case of a so-called smart gaming machine, and a game is played using the game medal information stored in the IC card, a counting switch having the same function as the settlement switch 28 is provided. When this counting switch is turned on, the game medal information bet on the slot machine is returned to credit, and the credited game medal information is transmitted to the dedicated unit and added to the game medal information stored in the IC card. Hereinafter, the process executed when the settlement switch 28 (the counting switch in a so-called smart gaming machine) is operated is referred to as the "return process".

[0013] The inside of the medal insertion port 22 branches into an acceptance passage (leading to a hopper 51 described later) through which the inserted game medal passes if the inserted game medal is validly accepted, and a return passage (leading to a medal payout outlet 41 described later) through which the inserted game medal passes if the inserted game medal is not accepted, and a blocker is provided at the branching point. This blocker is configured to selectively open one of the acceptance passage and the return passage and close the other, so that the blocker guides the game medal inserted into the medal insertion port 22 to the acceptance passage during the period when the inserted game medal is validly accepted, and guides the game medal inserted into the medal insertion port 22 to the return passage during the other period.

[0014] Inside the medal insertion port 22, there are provided two medal insertion sensors for detecting game medals inserted into the medal insertion port 22 and validly received, and a medal passage sensor for monitoring the game medals inserted into the medal insertion port 22. The first medal insertion sensor is a transmission type optical sensor capable of detecting game medals, and is disposed downstream of the position where the blocker is installed (closer to the hopper 51 described below). The second medal insertion sensor is also a transmission type optical sensor capable of detecting game medals, and is disposed next to the downstream side of the first medal insertion sensor. The medal passage sensor is a contact type sensor capable of detecting game medals, and is disposed downstream of the position where the blocker is installed and closest to the medal insertion port 22 (upstream of the two medal insertion sensors).

[0015] When the first and second medal insertion sensors detect the passage of game medals in this order, it means that the game medals have been inserted into the medal insertion port 22 and that the inserted game medals have been accepted validly. On the other hand, when the first and second medal insertion sensors detect the passage of game medals in the reverse order (the second, first order), it means that an abnormal passage such as a backward flow of game medals has occurred. Also, when the medal passage sensor (or at least one of the two medal insertion sensors) continues to detect game medals for more than a predetermined time, it means that an abnormality has occurred such as a game medal being stuck in the receiving passage or a foreign object (such as a tool for cheating) being inserted from the medal insertion port 22 into the receiving passage.

[0016] The reel window W is configured so that when the left reel 3a, the center reel 3b, and the right reel 3c all stop, three consecutive symbols for each reel, totaling nine symbols, are displayed so as to be visible to the player. Here, of the three symbols of each reel displayed in the reel window W, the uppermost symbol display position is called the upper row, the lowermost symbol display position is called the lower row, and the symbol display position between the upper row and the lower row is called the middle row. A winning line 29 that connects the symbol display areas of the middle rows of the reels 3a to 3c horizontally (in a horizontal straight line) is a winning line that is activated when a specified number of game medals are bet, and the game is configured so that the presence or absence of a game combination is determined by the symbol combination stopped and displayed on the activated winning line 29.

[0017] In addition, various display lamps composed of LED lamps and the like are arranged on the central panel CPL of the middle panel assembly 20. In this embodiment, the display lamps include a MAX-BET switch display lamp (not shown) -BET number display lamp 46b, an insert possible display (INSERT) lamp 46c, a game start display (START) lamp 46d, a replay display (REPLAY) lamp 46e, a status display (GAME OVER) lamp 46f, a number of reserved coins display (CREDIT) lamp 46h, and a payout number display (PAYOUT) lamp 46j. These display lamps are configured to be controlled by a main control board 110 described later.

[0018] The MAX-BET switch indicator lamp (not shown) is turned on when a game medal can be bet, and is disposed inside the MAX-BET switch (not shown) provided in the -BET switch unit 23, and when turned on, causes the MAX-BET switch to light up partially or entirely. The other indicator lamps are disposed on the sides or below the reel window W in the central panel CPL of the middle panel assembly 20.

[0019] The bet number indicator lamp 46b indicates the number of game medals bet, and is composed of a 1-BET indicator lamp 46bC that is turned on when one game medal is bet, a 2-BET indicator lamp 46bB that is turned on when two game medals are bet, and a 3-BET indicator lamp 46bA that is turned on when three game medals are bet. The insertion possible indicator lamp 46c is turned on when game medals can be inserted, and the game start indicator lamp 46d is turned on when a game can be started by operating the start lever 25. The replay indicator lamp 46e is turned on when a replay role is established in any game and game medals are automatically bet by the automatic bet process.

[0020] The status display lamp 46f is turned on when the bet game medals and / or the stored game medals are settled. The stored number display lamp 46h is a 7-segment display of the number of stored (credited) game medals, and the payout number display lamp 46j is a 7-segment display of the number of game medals to be paid out when a minor winning combination (a game combination configured to pay out a predetermined number of game medals when the combination is achieved) is achieved.

[0021] The payout number display lamp 46j is also configured to display letters (alphabets) or numbers (error code) indicating the type of error when some abnormality (error) occurs in the slot machine 1. Furthermore, the payout number display lamp 46j also has a function of displaying a navigation number (symbols or numbers) indicating the operation order (push order) of the stop switches 26a to 26c.

[0022] A transparent lower panel cover 31 is attached to the center of the lower panel assembly 30, and a pair of lower speakers 32a, 32b are arranged on the left and right sides of the transparent lower panel cover 31. A translucent lower panel base with a predetermined pattern and a lower panel illumination lamp (neither shown) are attached to the back side of the lower panel cover 31, and the pattern on the lower panel base is illuminated from behind by turning on the lower panel illumination lamp.

[0023] The tray assembly 40 is provided with a medal payout outlet 41 for paying out medals, and is provided with a medal storage tray 42 for storing medals, facing the medal payout outlet 41. An ashtray 43 is provided to the left of the medal storage tray 42.

[0024] <Internal structure of a slot machine> As shown in FIG. 3, a medal payout device 50 is provided in the lower part (above the bottom plate 5d) of the cabinet 5, which pays out game medals acquired when a predetermined winning mode is formed as a result of playing. The medal payout device 50 has a hopper 51 that physically stores (stores) game medals that are inserted from the medal insertion port 22 and are validly received, and an ejection port 52 that ejects the game medals stored in the hopper 51 one by one. An auxiliary storage 53 for storing game medals that have overflowed from the hopper 51 is provided in the vicinity of the medal payout device 50, and a fullness detection unit (not shown) for detecting whether the auxiliary storage 53 is full (a state in which game medals may overflow from the auxiliary storage 53) is provided. In addition, a power supply device 55 for supplying power to various devices mounted on the slot machine 1 is provided to the left of the medal payout device 50.

[0025] In the center of the cabinet 5, a middle plate 5f is provided so as to span the left and right side plates 5a and 5b, and a reel unit 60 is provided on the middle plate 5f. The reel unit 60 is configured with the above-mentioned three reels 3a, 3b, and 3c, and three stepping motors (described later) for rotating the reels 3a to 3c, respectively. The left reel 3a, the middle reel 3b, and the right reel 3c are each made of a translucent material, and a translucent reel tape on which a plurality of types of patterns are displayed is attached to the outer circumferential surface. In addition, a back lamp (described later) is disposed on the inner surface of each of the reels 3a to 3c. An external centralized terminal board 80 is disposed on the upper part of the right side plate 5b, which outputs information related to the game to an external hall computer or the like. The output information related to the game includes, for example, the number of inserted medals, the number of paid-out medals, and the number of times that a so-called bonus game or AT game has started.

[0026] A main control device 100 that mainly controls the progress of the game is provided in the upper part of the cabinet 5 (the upper inner surface of the back panel 5e). For example, when a specified number of game medals (for example, three medals) are inserted and the start lever 25 is operated, the main control device 100 performs a prize draw and starts the rotation drive of the reels 3a to 3c, and when the stop switches 26a, 26b, and 26c are stopped, the main control device 100 performs stop control of the reels based on the result of the prize draw. Here, the first stop operation of the stop switch performed when all the reels are rotating is called the first stop operation. Moreover, after the first stop operation, the second stop operation of the stop switch performed when the remaining two reels are rotating is called the second stop operation. Moreover, after the second stop operation, the last stop operation of the stop switch performed when the remaining one reel is rotating is called the third stop operation. When all the reels have stopped, if a symbol combination of a small winning combination is aligned on the winning line 29 (a small winning combination is won), the medal payout device 50 is controlled to pay out medals in the number corresponding to the winning small winning combination.

[0027] <Front door rear configuration> FIG. 4 shows a front view of the front door 2 as seen from the rear. Since FIG. 4 illustrates the front door 2 as seen from the rear, the left and right directions of the arrows in FIG. 4 are reversed from those in FIG. 2. On the rear side (back side) of the front door 2, the sub-controller 500 is provided above the reel window W. The sub-controller 500 controls various performance devices such as the first performance lamp 12, the second performance lamps 13a, 13b, the liquid crystal display device 11, and the upper speakers 15a, 15b based on various commands transmitted from the main control device 100, thereby executing various performances to enhance the interest of the game according to the game situation. These functions are realized by various components mounted on a sub-control board (described later) housed in the sub-board case 501. The sub-controller 500 and the main control device 100 are electrically connected to each other using a cable harness, and information transmission between these devices can be performed only in one direction, from the main control device 100 to the sub-controller 500.

[0028] A medal selector 650 is provided below and to the right of the reel window W, which selects whether or not a game medal inserted from the medal insertion port 22 can be validly accepted. If the game medal inserted from the medal insertion port 22 can be validly accepted, the medal selector 650 passes it to a receiving passage 71 leading to the hopper 51, and if the game medal cannot be validly accepted, the medal selector 650 causes it to flow down to a return passage 72 leading to the game medal payout outlet 41. In addition, a medal passing port 73 is formed in the return passage 72 so as to be aligned with the game medal ejection port 52 provided in the medal payout device 50.

[0029] <Main control unit configuration> Next, the configuration of the main control device 100 according to this embodiment will be described with reference to Figs. 5 to 13. As shown in Figs. 7 to 9, the main control device 100 is configured to include a main control board 110 and a main board case 210 that houses the main control board 110. As shown in Fig. 8, the main control board 110 is configured to include a control chip 121, an information display lamp 156, a plurality of electrical connectors such as a main board side connector 161, and a printed board 111 on which these various components are mounted. In addition, the various components mounted on the printed board 111 are mounted on a surface portion (also referred to as a "first surface portion" or "board mounting surface") FS of the printed board 111. Therefore, when the main control device 100 is installed on the back plate 5e (see Fig. 3) of the housing 5, the surface portion FS faces forward and is aligned in the vertical direction. The details of the main control board 110 will be described later.

[0030] As shown in Figs. 7 to 9, the main board case 210 has a case body 211 and a case lid 221, and is configured to be able to store the main control board 110 inside the case formed by joining the case body 211 and the case lid 221. As shown in Fig. 8, the case body 211 is formed of a transparent resin material in a substantially rectangular box shape that opens forward, and a plurality of coupling grooves 212 are formed in the upper and lower wall portions. The coupling grooves 212 are L-shaped grooves that are composed of an insertion groove portion that opens forward and a locking groove portion that extends rightward from the rear of the insertion groove portion. The case lid 221 is formed of a transparent resin material in a substantially rectangular box shape that opens backward, and a plurality of engagement protrusions (not shown) are formed on the inner surfaces of the upper and lower walls at positions corresponding to the coupling grooves 212. This engagement protrusion is inserted from the front into the insertion groove of the coupling groove 212 of the case body 211, and the case lid 221 is slid to the right relative to the case body 211 to insert the engagement protrusion into the locking groove of the coupling groove 212, thereby restricting the movement of the case lid 221 relative to the case body 211 in the forward / backward, up / down and rightward directions, and the case body 211 and the case lid 221 are coupled together.

[0031] As shown in FIG. 8 and FIG. 10, the right part of the case body 211 is formed with a body side joint 213 and a first body side sealing part 214 to which the sealing cover 241 is attached. A lid crimping member (not shown) having a locking claw is to be attached inside the body side joint 213. Two case mounting projections 219 protruding to the right are formed on the right side surface of the first body side sealing part 214. The left part of the case body 211 is formed with a body side temporary engagement part 215 that can be engaged with a used body crimping member 340 (see FIG. 11) when recovering the main board case 210. The lower part of the case body 211 is formed with a second body side sealing part 216. The left front part of the case body 211 is formed with a board support projection 217 that supports the main control board 110 so as not to bend.

[0032] 7 and 8, the right part of the case lid 221 is formed with a lid side joint 223 which is joined with the body side joint 213 of the case body 211 and a first lid side seal part 224 which is joined with the first body side seal part 214 of the case body 211 when the case body 211 and the case lid 221 are joined as described above. When the body side joint 213 and the lid side joint 223 are joined, a locking claw of a lid crimping member (not shown) mounted in the body side joint 213 is inserted into a locking groove in the lid side joint 223, thereby restricting the sliding movement of the case lid 221 to the left relative to the case body 211 (in the direction in which the case lid 221 is removed), and the case lid 221 is fixed so that it cannot be removed from the case body 211. In addition, a sealing sticker 242 is affixed across the first body side sealing part 214 and the first lid side sealing part 224, and a sealing cover 241 is slid from the right and attached to the first body side sealing part 214 and the first lid side sealing part 224 so as to cover the sealing sticker 242. After the sealing cover 241 is attached to the first body side sealing part 214 and the first lid side sealing part 224, a cutter member 243 is attached to the sealing cover 241 so that the cutting part of the cutter member 243 is disposed inside the sealing cover 241. Therefore, when the sealing cover 241 is slid leftward to be removed, the sealing sticker 242 is cut by the cutting part of the cutter member 243.

[0033] A cover part 225 is formed on the left side of the case lid 221, which accommodates and covers the body side temporary engagement part 215 of the case body 211 when the case body 211 and the case lid 221 are joined as described above. An upper case fixing part 225a is formed on the upper part of the cover part 225, which can be engaged with a body crimping member 340 (see FIG. 11) described later and can also face a crimping type member 345 (see FIG. 11) described later. A lower case fixing part 225b is formed on the lower part of the cover part 225, which can be opposed to the crimping type member 345 and can also engage with the body crimping member 340. A cover side temporary engagement part 225c is formed on the middle part of the cover part 225, which can engage a used body crimping member 340 while overlapping with the body side temporary engagement part 215 of the case body 211.

[0034] At the upper left end of the case lid 221, a Nylatch-type upper temporary fastener 238a is formed, which can be inserted into an upper temporary fastening hole 348a (see FIG. 11) of a bracket member 330 described later. At the lower left end of the case lid 221, a Nylatch-type lower temporary fastener 238b is formed, which can be inserted into a lower temporary fastening hole 348b (see FIG. 11) of the bracket member 330. At the lower part of the case lid 221, a second lid-side sealing part 226 is formed, which is coupled to the second body-side sealing part 216 of the case body 211. When the second body-side sealing part 216 and the second lid-side sealing part 226 are coupled, a laser device or the like is used to print across the second body-side sealing part 216 and the second lid-side sealing part 226, thereby sealing the main board case 210.

[0035] A left connector exposing portion 227 that penetrates from front to back is formed on the left side of the front surface of the case lid 221 to expose, forward, the main board side connector 161 of the main control board 110 housed inside the case. A cable connector 192 provided at one end of a front door cable harness 191 can be fitted and connected to the main board side connector 161 exposed via the left connector exposing portion 227 (see FIG. 5).

[0036] A connector cover 246 that covers the left connector exposed portion 227 from the front is attached to the case lid 221. A groove-shaped first cover crimping attachment portion 229 is formed on the front surface of the case lid 221, and a first cover crimping member 228 having a locking claw can be attached by sliding it from above to the first cover crimping attachment portion 229. When the connector cover 246 is attached to the case lid 221, the first cover crimping member 228 attached to the first cover crimping attachment portion 229 is disposed inside the connector cover 246, and the locking claw of the first cover crimping member 228 is inserted into the locking groove in the connector cover 246. Therefore, the connector cover 246 is fixed so that it cannot be removed from the case lid 221 unless the connector cover 246 is destroyed to release the locking state with the first cover crimping member 228.

[0037] The front lower side of the case lid 221 is formed with first to fourth lower connector exposure parts 231 to 234 that penetrate forward and backward to expose the reel connector 162, the sub-substrate connector 163, the setting change device connector 164, and the collator connector 165 of the main control board 110 accommodated inside the case. The reel connector 162 exposed through the first lower connector exposure part 231 is adapted to be fitted and connected to a connector of a cable harness (not shown) electrically connected to a reel control board (not shown). The sub-substrate connector 163 exposed through the second lower connector exposure part 232 is adapted to be fitted and connected to a connector of a cable harness (not shown) electrically connected to the sub-control device 500. The setting change device connector 164 exposed through the third lower connector exposure part 233 is adapted to be connected to a connector of a cable harness (not shown) electrically connected to the setting change device 350. The collator connector 165 exposed through the fourth lower connector exposure portion 234 is designed to be fitted and connected to a connector of a cable harness (not shown) electrically connected to the collator (not shown).

[0038] A seal attachment section 235 to which a crimping usage record seal 248 is attached is formed in the center of the front surface of the case lid 221. The seal attachment section 235 is formed in a rectangular recess shape that matches the outer periphery of the crimping usage record seal 248. The crimping usage record seal 248 is formed in the shape of a transparent sheet on which characters or figures are printed for writing the date when the main board case 210 was sealed, etc. (hereinafter referred to as a crimping usage record).

[0039] A recess 237 is formed on the inside of the case lid 221 at a portion of the case lid 221 that overlaps with the information display lamp 156 of the main control board 110. As shown in Figs. 7 to 9, the recess 237 has a bottom 237e that is lower than the ceiling of the case lid 221, and an upper wall 237a, a lower wall 237b, a left wall 237c, and a right wall 237d that surround the front side of the bottom 237e from above, below, left, and right. The bottom 237e is formed in a flat plate shape that overlaps with the information display lamp 156 and extends approximately parallel to it in the vicinity of the front of the information display lamp 156. The upper wall 237a, the lower wall 237b, and the left wall 237c are formed in a wall shape that extends in the front-rear direction. Of the top, bottom, left and right walls 237a to 237d, the right wall 237d located farther from the hinge mechanisms 6a to 6c is formed in a wall shape that slopes to the right (farther from the hinge mechanisms 6a to 6c) as it approaches the front.

[0040] The main board case 210, which thus houses the main control board 110 inside the case, is attached to the upper part of the housing 5 (the upper inner surface of the back plate 5e) via the board case attachment mechanism 300, as shown in FIG. 5. As shown in FIG. 11 and FIG. 12, the board case attachment mechanism 300 is configured to include a left base member 310 attached to the upper left part of the back plate 5e, a right base member 320 attached to the upper right part of the back plate 5e, and a bracket member 330 attached to the left base member 310 so as to be swingable in the front-rear direction. The main board case 210 is attached to the inside of the bracket member 330 facing forward. The left end of the bracket member 330 is connected to the left base member 310 so as to be swingable in the front-rear direction. On the other hand, the right end of the bracket member 330 is configured to be fixed to the right base member 320 using a lock member 360. As a result, the main board case 210 is swingably attached to the upper part of the housing 5 via the board case attachment mechanism 300.

[0041] The left side base member 310 is formed in a block shape extending in the vertical direction, and is attached to the upper left side of the back plate 5e of the housing 5 (near the lower side of the top plate 5c) using a mounting screw (not shown). The left side base member 310 is formed with three base side engagement parts 311, 312, 313 arranged in the vertical direction, each having a hinge hole that can be engaged with the bracket side engagement parts 331, 332, 333 of the bracket member 330. The right side base member 320 is formed in a block shape extending in the vertical direction, and is attached to the upper right side of the back plate 5e of the housing 5 (near the lower side of the top plate 5c) using a mounting screw (not shown). The right side base member 320 is configured so that a locking protrusion part (not shown) provided on the right side of the rear surface of the bracket member 330 can be locked.

[0042] The bracket member 330 is formed of a transparent resin material in a generally rectangular box shape that opens forward, and the main board case 210 is attached to the internal space of the bracket member 330 to support the main board case 210. On the outer surface side of the left wall of the bracket member 330, three bracket side engagement parts 331, 332, 333 having hinge shafts that can be rotatably engaged with the base side engagement parts 311, 312, 313 of the left base member 310 are formed side by side in the vertical direction. As a result, the left end part of the bracket member 330 is connected to the left base member 310 so as to be swingable in the front-rear direction with the base side engagement parts 311, 312, 313 engaged with the bracket side engagement parts 331, 332, 333.

[0043] At a position adjacent to the left side wall within bracket member 330, upper and lower case crimping attachment parts 334, 335 are formed, to which main body crimping member 340 and crimping type member 345 are attached. Main body crimping member 340 (or crimping type member 345) having a locking claw is inserted and attached from an opening formed on the right side to upper case crimping attachment part 334. Crimping type member 345 (or main body crimping member 340) without a locking claw is inserted and attached from an opening formed on the right side to lower case crimping attachment part 335.

[0044] An upper temporary fixing hole 348a into which the upper temporary fixing device 238a of the main board case 210 (case lid 221) can be inserted is formed at the upper left end portion within the bracket member 330. A lower temporary fixing hole 348b into which the lower temporary fixing device 238b of the main board case 210 (case lid 221) can be inserted is formed at the lower left end portion within the bracket member 330. In addition, a cable clamp 336 capable of fixing and holding the front door cable harness 191 described above is formed at the lower left portion of the bracket member 330.

[0045] A lock member 360 for fixing the bracket member 330 to the right base member 320 is attached to the upper right portion of the bracket member 330. Case mounting holes 339, 339 that open to the left are formed in a vertical line in the upper right portion of the bracket member 330. Case mounting protrusions 219, 219 of the main board case 210 (case main body 211) can be inserted into the case mounting holes 339, 339 from the left.

[0046] To mount the main board case 210 housing the main control board 110 inside the case to the bracket member 330, the case mounting protrusions 219, 219 of the main board case 210 are inserted into the case mounting holes 339, 339 of the bracket member 330, and then the upper and lower temporary fasteners 238a, 238b of the main board case 210 are inserted into the upper and lower upper temporary fastening holes 348a, 348b of the bracket member 330, and the main board case 210 is inserted into the bracket member 330. When the main board case 210 is inserted into the bracket member 330, the main body crimping member 340 mounted on the upper case crimping mounting portion 334 is disposed inside the upper case fixing portion 225a of the main board case 210, and the locking claw of the main body crimping member 340 is inserted into the locking groove in the upper case fixing portion 225a. At the same time, the crimping member 345 attached to the lower case crimping attachment portion 335 is disposed facing the inside of the lower case fixing portion 225b of the main board case 210. This fixes the main board case 210 so that it cannot be removed from the bracket member 330 unless the upper case fixing portion 225a of the main board case 210 is destroyed to release the locked state with the main body crimping member 340.

[0047] In this manner, the main board case 210 is attached to the bracket member 330 by first engaging the right side of the main board case 210 with the bracket member 330, and then engaging the left side. It is also possible that the crimping member 345 is attached to the upper case crimping attachment portion 334 and disposed facing each other inside the upper case fixing portion 225a, and the main body crimping member 340 is attached to the lower case crimping attachment portion 335 and disposed inside the lower case fixing portion 225b, and the locking claw of the main body crimping member 340 is inserted into the locking groove in the lower case fixing portion 225b. This allows the main board case 210 to be attached to the bracket member 330 twice by switching the vertical positions of the main body crimping member 340 and the crimping member 345.

[0048] For example, when first mounting main board case 210 to bracket member 330, main body crimping member 340 is mounted to upper case crimping mounting portion 334, crimping member 345 is mounted to lower case crimping mounting portion 335, and the locking claws of main body crimping member 340 are inserted into locking grooves in upper case fixing portion 225a of main board case 210. In this state, when main board case 210 is removed from bracket member 330, upper case fixing portion 225a of main board case 210 is destroyed to release the locking state with main body crimping member 340. Next, when the removed main board case 210 is attached again to the bracket member 330, a crimping member 345 is attached to the upper case crimping attachment portion 334, and a main body crimping member 340 is attached to the lower case crimping attachment portion 335, and the locking claws of the main body crimping member 340 are inserted into the locking grooves in the lower case fixing portion 225b of the main board case 210. Then, when the main board case 210 is removed from the bracket member 330, the lower case fixing portion 225b of the main board case 210 is destroyed to release the locking state with the main body crimping member 340. Furthermore, when a manufacturer or the like collects the main board case 210 removed from the bracket member 330, the used main body crimping member 340 removed from the lower case crimping attachment portion 335 (or the upper case crimping attachment portion 334) is engaged with the main body side temporary engagement portion 215 and the lid side temporary engagement portion 225c of the main board case 210. This restricts the sliding movement of the case lid 221 to the left (in the direction in which the case lid 221 is removed) relative to the case body 211 of the main board case 210, making it possible to fix the case lid 221 so that it cannot be removed from the case body 211.

[0049] In addition to the main board case 210 being attached to the bracket member 330, the setting change device 350 is also attached to the bracket member 330. Specifically, the setting change device 350 is attached to the lower right part of the bracket member 330. To the left of the setting change device 350 in the lower right part of the bracket member 330, a cable cover 355 is attached to cover a cable harness (not shown) that extends from the setting change device 350 to the main control board 110 (connector 164 for setting change device) in the main board case 210. A groove-shaped second cover crimping attachment part 338 is formed in the lower right part of the bracket member 330, and a second cover crimping member 337 having a locking claw can be slid from the right side to the second cover crimping attachment part 338 and attached. When cable cover 355 is attached to bracket member 330, second cover crimping member 337 attached to second cover crimping attachment portion 338 is disposed inside cable cover 355, and the locking claws of second cover crimping member 337 are inserted into locking grooves in cable cover 355. Therefore, cable cover 355 is fixed so that it cannot be removed from bracket member 330 unless cable cover 355 is destroyed to release the locked state with second cover crimping member 337.

[0050] The setting change device 350 is a device operated when changing the setting value (such as the probability of winning a game role) of the slot machine 1 that determines the degree of advantage for the player. When a setting change key (not shown) is inserted into a setting change key cylinder (not shown) provided in the setting change device 350 and rotated about 90 degrees rightward (clockwise), the power switch of the power supply device 55 provided at the bottom of the cabinet 5 is turned ON to start the setting change mode (a mode in which the setting value can be changed). Here, the setting change key cylinder and the setting change key are collectively referred to as the setting key switch. The setting change device 350 switches the above-mentioned setting value among six levels from 1 to 6 every time the setting change switch (not shown) is pressed, and displays the setting value on the setting display lamp 151 (see FIG. 13) provided on the main control board 110. Then, when the start lever 25 provided on the front of the front door 2 is operated, the above-mentioned setting value is confirmed, and when the setting change key is returned to its original position, the setting change mode ends and the mode shifts to the normal mode. Furthermore, when the setting change key inserted into the setting change key cylinder is rotated about 90 degrees to the right (clockwise) in the normal mode, the main control board 110 starts the setting confirmation mode and displays the current setting value on the setting display lamp 151 on the main control board 110. Then, when the setting change key is returned to its original position, the setting confirmation mode ends and the mode transitions to the normal mode.

[0051] <Main control board configuration> Next, the detailed configuration of the main control board 110 according to this embodiment will be described with reference to Fig. 13. As shown in Fig. 13, the main control board 110 is configured to have a control chip 121, a plurality of ICs (also referred to as "IC parts" or "IC drivers"), a monitor lamp 141 also referred to as a monitor LED, a setting display lamp 151 also referred to as a setting display monitor, an information display lamp 156 also referred to as a role ratio monitor (corresponding to a performance display monitor in a pachinko game machine), a plurality of electric connectors such as a main board side connector 161, and a printed circuit board 111 on which these are mounted. The main control board 110 is configured to control the progress of the game in the slot machine 1 by operating each drive circuit etc. according to a control program stored in the ROM of the control chip 121. Further, although detailed illustration is omitted (some are illustrated by way of example and numbered), in main control board 110, a plurality of capacitors including film capacitor 171, ceramic capacitor 172, electrolytic capacitor 173, and general capacitor 174, a plurality of transistors 175, a plurality of diodes 176, a plurality of resistor arrays 177, and a plurality of resistors 178 are mounted on printed circuit board 111. The capacitors of main control board 110 are used, for example, to stabilize the power supply of each IC. The transistors of main control board 110 are used, for example, to drive each output circuit. The diodes of main control board 110 are used, for example, as static electricity countermeasures for each IC.

[0052] The elements mounted on the printed circuit board 111, excluding electrical connectors, such as the control chip 121, the multiple ICs, the monitor lamp 141, the setting display lamp 151, and the information display lamp 156, are covered by the case lid 221 of the main board case 210 when the main control board 110 is housed in the main board case 210. As described above, the main board case 210 is formed using a transparent resin material, and is configured so that the control chip 121, the multiple ICs, the monitor lamp 141, the setting display lamp 151, the information display lamp 156, and the like can be seen from the outside of the case lid 221.

[0053] A rectangular sticker pasting area AS is set on the upper central side of the main control board 110 (printed board 111). The sticker pasting area AS is an area that may overlap with the crimped use record sticker 248 pasted on the sticker pasting portion 235 of the case cover 221 when viewed from the outside of the case cover 221. A rectangular solvent inflow area BS extending vertically is set on the right end of the main control board 110. The solvent inflow area BS is an area where, when attempting to peel off the sealing sticker 242 of the main board case 210, the solvent used to peel off the sealing sticker 242 may flow into the main control board 110 inside the case. To the left and below the sticker pasting area AS in the main control board 110, a placement restriction area CS extending in a substantially L-shape is set. The placement restricted area CS is close to the left side wall portion 221a and the lower wall portion 221b (see FIG. 8) of the case lid 221, and is an area in which placement of the setting display lamp 151 and the information display lamp 156 is restricted because visibility may be hindered.

[0054] In addition, in the upper right portion of the printed circuit board 111, a drawing section 112 is provided on which the name of the board manufacturer is printed by a laser device or the like in order to prove that the main control board 110 is not an unauthorized board. This drawing section 112 is also covered by the case lid 221 of the main board case 210 when the main control board 110 is housed in the main board case 210, and is configured so that the drawing section 112 can be seen from the outside of the case lid 221. The drawing section 112 on which the name of the board manufacturer is drawn is disposed in a position that is not a sticker attachment area AS so that the name of the board manufacturer can be easily confirmed. Note that the name of the board manufacturer is not limited to being composed of characters only, and may be, for example, a combination of characters and a corporate mark, or may be a configuration including at least one of characters and figures.

[0055] The information display lamp 156 (and the setting display lamp 151) has a shape that is thicker than other electric elements, and if the drawing unit 112 is placed near the information display lamp 156 (and the setting display lamp 151), there is a possibility that the drawing unit 112 will be hidden in the shadow of the information display lamp 156 (and the setting display lamp 151) and its visibility will be reduced. Therefore, the drawing unit 112 is placed at a position away from the information display lamp 156 (and the setting display lamp 151) by a distance that does not impede the visibility of the drawing unit 112 when viewed from the outside of the case lid 221. The name of the board manufacturer is printed after all the electric elements are mounted on the printed board 111. The soldered parts of the information display lamp 156 (and the setting display lamp 151) have a structure that is relatively weak against heat and fragile. Therefore, when printing the name of the board manufacturer using a laser device, it is preferable to position the drawing unit 112 away from the information display lamp 156 (and the setting display lamp 151) in order to prevent the heat of the laser from affecting the information display lamp 156 (and the setting display lamp 151).

[0056] The control chip 121 is configured to have a CPU that performs various arithmetic processing related to the game, a ROM that is a read-only memory device that stores control programs and the like, and a RAM that is a memory device that can write and read information. The control chip 121 is mounted on the right side of the center of the printed circuit board 111, that is, on the side of the printed circuit board 111 farther from the hinge mechanisms 6a to 6c. In order to make it easier to check whether or not the control chip 121 has been tampered with, the control chip 121 is placed in a position that is not a sticker attachment area AS. In addition, it is preferable that the control chip 121 is placed in a position that is not a solvent inflow area BS so that the control chip 121 is not adversely affected by the solvent. In addition, the control chip 121 is placed in a position that is away from the setting display lamp 151 and the information display lamp 156 by a distance that allows the first to third display control ICs 132A to 132C to be placed.

[0057] The ICs include first to second oscillator ICs 131A to 131B, first to third display control ICs 132A to 132C, and first to eleventh main board ICs 133A to 133K. The first to second oscillator ICs 131A to 131B are electrically connected to the control chip 121 and configured to generate a clock used in the control chip 121. The first to second oscillator ICs 131A to 131B are mounted on the right side of the center of the printed board 111. The first to second oscillator ICs 131A to 131B are arranged in a position that is not in the sticker attachment area AS, near the lower side of the control chip 121. The first to second oscillator ICs 131A to 131B may be arranged in a position that is in the sticker attachment area AS, as long as they are in the vicinity of the control chip 121. This is because, unlike the control chip 121, there is less need to easily check whether or not any tampering has occurred.

[0058] The first to third display control ICs 132A to 132C are ICs for performing dynamic lighting control of the seven-segment LEDs of the reserved number display lamp 46h, the dispensed number display lamp 46j, the setting display lamp 151, and the information display lamp 156. The first display control IC 132A is electrically connected to the control chip 121, and is also electrically connected to the main board side connector 161, the setting display lamp 151, and the information display lamp 156. The first display control IC 132A functions as a segment driver that sets (decodes) numbers and the like (numbers, alphabets, various symbols, etc.) displayed on the reserved number display lamp 46h, the dispensed number display lamp 46j, the setting display lamp 151, and the information display lamp 156 in response to a control signal transmitted from the control chip 121.

[0059] The second display control IC 132B is electrically connected to the control chip 121, and is also electrically connected to the main board side connector 161 and the setting display lamp 151. The second display control IC 132B functions as a digit driver that switches whether to display numbers, etc. (set by the first display control IC 132A, which is a segment driver) on any of the digits (each digit) of the storage number display lamp 46h, the payout number display lamp 46j, and the setting display lamp 151 in response to a control signal transmitted from the control chip 121. The third display control IC 132C is electrically connected to the control chip 121, and is also electrically connected to the information display lamp 156. The third display control IC 132C functions as a digit driver that switches whether to display numbers, etc. (set by the first display control IC 132A, which is a segment driver) on any of the digits (each digit) of the information display lamp 156 in response to a control signal transmitted from the control chip 121.

[0060] The first to third display control ICs 132A to 132C are mounted on the left side of the center of the printed circuit board 111, that is, on the side closer to the hinge mechanisms 6a to 6c on the printed circuit board 111. The first display control IC 132A is disposed to the left of the eleventh main board IC 133K in a position that will be the sticker attachment area AS. The second display control IC 132B is disposed below the first display control IC 132A in a position that will not be the sticker attachment area AS. The third display control IC 132C is disposed above the first display control IC 132A in a position that will be the sticker attachment area AS. All of the first to third display control ICs 132A to 132C may be disposed in positions that will be the sticker attachment area AS. This is because, like the first and second oscillator ICs 131A to 131B, there is little need to easily check whether or not tampering has occurred.

[0061] The other ICs, 1st to 11th main board ICs 133A to 133K, are mounted on various parts of printed board 111. For example, as shown in Fig. 13, the main board ICs mounted on the right side of printed board 111 are the 1st main board IC 133A, the 2nd main board IC 133B, and the 3rd main board IC 133C. Also, for example, the main board ICs mounted on the upper central part of printed board 111 are the 4th main board IC 133D, the 5th main board IC 133E, the 6th main board IC 133F, the 7th main board IC 133G, the 8th main board IC 133H, the 9th main board IC 133I, the 10th main board IC 133J, and the 11th main board IC 133K. Hereinafter, when the first to eleventh main board ICs 133A to 133K are referred to collectively, they will be referred to as "main board ICs 133."

[0062] These main board ICs 133 include a driver IC that shapes the waveforms of on / off signals (digital signals indicating two states of a switch, on and off) of various switches input from outside, and a latching IC that houses multiple latch circuits that hold the on / off signals of various switches. The above-mentioned "various switches" include the BET switch unit 23, the start lever 25, the stop switches 26a, 26b, and 26c, and the settlement switch 28 shown in FIG. 1, and the setting key switch and setting change switch of the setting change device 350 shown in FIG. 5. "Shaping the waveform" means, for example, returning the voltage value of the high level to a more appropriate voltage value when the voltage value of the high level drops or the voltage value of the low level rises, and returning the rising and falling edges of the signal to a steeper value when the rising and falling edges of the signal become gradual.

[0063] The control chip 121 performs processing for progressing the game according to the on / off signals of various switches shaped by the driver IC described above. For example, when a specified number of game medals are bet (inserted) and the on / off signal of the start lever 25 changes from off to on, processing for rotating the reels 3a, 3b, and 3c is performed. Also, when the on / off signal of the stop switch corresponding to the rotating reel changes from off to on, processing for stopping the reel is performed. Also, when the on / off signal of the setting change switch changes from off to on in the setting change mode described above, the setting value is changed. Also, when the on / off signal of the setting key switch changes from off to on when a game is not being played, the current setting value is displayed on the setting display lamp 151 on the main control board 110. Furthermore, when the game medals are credited and the on / off signal of the settlement switch 28 changes from off to on when a game is not being played, the main control board 110 operates the medal payout device 50 to return the credited game medals.

[0064] The first main board IC 133A is arranged above and to the right of the control chip 121. The second main board IC 133B is arranged above the control chip 121 and to the left of the first main board IC 133A. The third main board IC 133C is arranged below and near the control chip 121 and to the left of the first and second oscillator ICs 131A to 131B. The first to third main board ICs 133A to 133C are arranged in positions that do not constitute the sticker attachment area AS.

[0065] The fourth main board IC 133D is disposed above and to the left of the second main board IC 133B. The fifth main board IC 133E is disposed to the left of the fourth main board IC 133D. The sixth main board IC 133F is disposed below the fifth main board IC 133E. The seventh main board IC 133G is disposed below the sixth main board IC 133F. The eighth main board IC 133H is disposed below the seventh main board IC 133G. The ninth main board IC 133I is disposed to the left of the fifth main board IC 133E. The tenth main board IC 133J is disposed below the ninth main board IC 133I and to the left of the sixth main board IC 133F. The eleventh main board IC 133K is disposed below the tenth main board IC 133J and to the left of the seventh main board IC 133G. The fourth to eleventh main board ICs 133D to 133K are disposed in positions that will become sticker attachment areas AS.

[0066] The monitor lamp 141 is composed of 20 LED elements 142 arranged in two rows, 10 on each side, and emits light according to the operating state of each part of the slot machine 1. The monitor lamp 141 is for checking whether there is a malfunction or the like. For example, some of the 20 LED elements 142 constituting the monitor lamp 141 emit light when each of the reels 3a to 3c of the reel unit 60 is not located at a predetermined rotation reference position (or is located at the position). For example, the other part of the 20 LED elements 142 emit light when the start lever 25 is in a non-operated state (or in an operated state). The monitor lamp 141 is mounted on the lower central part of the printed circuit board 111 (below the 4th to 11th main board ICs 133D to 133K). In order to easily check the light-emitting state (on or off) of each LED element 142, the monitor lamp 141 is arranged at a position that is not a sticker attachment area AS. In order to prevent the solvent from adversely affecting the monitor lamp 141, it is preferable to place the monitor lamp 141 at a position that does not become the solvent inflow area BS. In addition, since the monitor lamp 141 is electrically connected to the main board side connector 161, it is preferable to place the monitor lamp 141 near the main board side connector 161.

[0067] The multiple electrical connectors include a main board side connector 161, a reel connector 162, a sub board connector 163, a setting change device connector 164, and a collator connector 165. The main board side connector 161 is mounted on the left end of the printed board 111, that is, on the side of the printed board 111 closer to the hinge mechanisms 6a to 6c than the first to third display control ICs 132A to 132C, the setting display lamp 151, and the information display lamp 156. As described above, the main board side connector 161 is adapted to be fitted and connected to the cable connector 192 provided at one end of the front door cable harness 191 (see FIG. 5).

[0068] The front door cable harness 191 is also electrically connected to a central display board 196 (see FIG. 5) disposed in the center of the rear side (rear side) of the front door 2. As shown in FIGS. 5 and 6, the front door cable harness 191 is wired from the housing 5 toward the front door 2 using a cable clamp 336 of the bracket member 330 and a plurality of cable clamps 194 disposed on the inner side of the left side plate 5a of the housing 5 (located on the side where the hinge mechanisms 6a to 6c are provided). At this time, the front door cable harness 191 is wired downward from the main board side connector 161 toward the cable clamp 336 of the bracket member 330 so as not to cover the front of the information display lamp 156 (and the setting display lamp 151) disposed near the main board side connector 161 and impede visibility. However, the front door cable harness 191 may cover the cover portion 225 of the case lid 221 arranged to the left of the main board side connector 161, and may hinder the visibility of the first and second case crimping members 340, 345, etc. Therefore, as described above, it is preferable to arrange the upper case fixing portion 225a that can engage with the main body crimping member 340 on the upper side of the cover portion 225 (relative to the lower case fixing portion 225b and the lid side temporary engagement portion 225c). In this embodiment, the front door cable harness 191 is shown by a two-dot chain line in Figures 5 and 6 to facilitate the explanation of the positional relationship with other parts. Also, on the inner side of the left side plate 5a, above the cable clamp 194, a sticker (hereinafter referred to as a "monitor LED list sticker LST") is attached on which a list is written that corresponds the part numbers identifying the LED elements 142 constituting the monitor lamp 141 described above and various switches and sensors corresponding to each LED element 142. The contents of this monitor LED list sticker LST will be explained in detail later.

[0069] The central display board 196 is electrically connected to a left relay board 197 and a right relay board 198, etc., provided on the left and right rear sides of the reel window W. The left relay board 197 and the right relay board 198 are mounted with or electrically connected to various display lamps (BET number display lamp 46b, insertion possible display lamp 46c, game start display lamp 46d, replay display lamp 46e, status display lamp 46f, stored number display lamp 46h, payout number display lamp 46j, etc.) arranged in the reel window W described above. As a result, a control signal for controlling the operation of the various display lamps is transmitted from the main control board 110 to the left relay board 197 and the right relay board 198 via the front door cable harness 191 and the central display board 196, and the operation of the various display lamps is controlled by the main control board 110.

[0070] Each of the relay boards described above, together with a cover that covers the relay board, is attached directly to the rear side of the front door 2 with a mounting screw, but the position of the mounting screw is determined so that it is not located directly above the board-mounted connector that fits with the cable harness described above on each relay board. Since the pins of a board-mounted connector are generally not covered with an insulating coating (i.e., the pins are exposed), by shifting the position of the mounting screw, if the mounting screw comes loose for some reason, the loose screw will not short-circuit the pins of the board-mounted connector.

[0071] As described above, the control signals for controlling the operation of the stored number display lamp 46h and the payout number display lamp 46j are configured to be output from the main board side connector 161 via the control chip 121, the first display control IC 132A, and the second display control IC 132B of the main control board 110. Control signals for controlling the operation of the BET number display lamp 46b, the deposit possible display lamp 46c, the game start display lamp 46d, the re-play display lamp 46e, etc. are also configured to be output from the main board side connector 161 via the control chip 121, the first display control IC 132A, and the second display control IC 132B of the main control board 110.

[0072] The reel connector 162 is mounted on the lower left side of the printed circuit board 111. As described above, the reel connector 162 is adapted to be fitted and connected to a connector of a cable harness (not shown) electrically connected to a reel control board (not shown). The sub-board connector 163 is mounted on the center of the lower end of the printed circuit board 111. As described above, the sub-board connector 163 is adapted to be fitted and connected to a connector of a cable harness (not shown) electrically connected to a sub-control board (not shown). The setting change device connector 164 is mounted on the lower left side of the printed circuit board 111. As described above, the setting change device connector 164 is adapted to be fitted and connected to a connector of a cable harness (not shown) electrically connected to the setting change device 350. The collator connector 165 is mounted on the lower left side of the printed circuit board 111 alongside the setting change device connector 164. As described above, the collating machine connector 165 is adapted to be fitted with the connector of a cable harness (not shown) electrically connected to the collating machine (not shown).

[0073] As described above, the setting display lamp 151 is a 7-segment display of the setting value of the slot machine 1 that determines the degree of advantage for the player. The setting display lamp 151 is configured using a 7-segment LED capable of displaying a single digit number. The setting display lamp 151 is mounted on the left side of the center of the printed circuit board 111, that is, on the side closer to the hinge mechanisms 6a to 6c than the control chip 121 on the printed circuit board 111. In order to make it easy to check the setting value displayed by the setting display lamp 151, the setting display lamp 151 is disposed at a position that is not within the sticker attachment area AS and the placement restriction area CS between the first display control IC 132A and the main board side connector 161.

[0074] The information display lamp 156 displays information related to the role ratio in seven segments. The information display lamp 156 is configured using a seven-segment LED capable of displaying four-digit numbers, etc. As information related to the role ratio, for example, a four-digit number combining a two-digit identifier code indicating the type of role ratio, etc. (role ratio, continuous role ratio, favorable period ratio, etc.) and a two-digit ratio corresponding to the identifier code can be displayed on the information display lamp 156. The information display lamp 156 is mounted on the left side of the center of the printed circuit board 111, that is, on the side closer to the hinge mechanisms 6a to 6c than the control chip 121 on the printed circuit board 111. In order to make it easier to check information related to the role ratio displayed on the information display lamp 156, the information display lamp 156 is disposed in a position that is not in the sticker attachment area AS or the placement restriction area CS between the first display control IC 132A and the third display control IC 132C. In addition, since there is a possibility that the information display lamp 156 may be blocked by the usage record sticker 248 when viewed from diagonally forward, it is not preferable to place the information display lamp 156 adjacent to the sticker affixing area AS. Therefore, it is preferable to place the information display lamp 156 at a distance to the left of the sticker affixing area AS that allows the information display lamp 156 to be viewed without being blocked by the crimped usage record sticker 248 even from diagonally forward to the right.

[0075] Moreover, unlike the control chip 121, the information display lamp 156 (and the setting display lamp 151) are reusable parts. Therefore, when an attempt is made to peel off the sealing seal 242 from the main board case 210 and the solvent used to peel off the sealing seal 242 flows into the main control board 110 inside the case, it is preferable that the solvent does not adhere to the information display lamp 156 (and the setting display lamp 151). Therefore, the information display lamp 156 (and the setting display lamp 151) are arranged at a position that does not become the solvent inflow area BS.

[0076] In order to efficiently form the conductor pattern on the printed circuit board 111 (without complicating it), it is preferable to mount the information display lamp 156 on the path of the conductor pattern between the first and third display control ICs 132A, 132C and the main board side connector 161. Therefore, the information display lamp 156 is disposed near the first and third display control ICs 132A, 132C and near the main board side connector 161. The information display lamp 156 is electrically connected to the first and third display control ICs 132A, 132C, and is spaced so close to the first and third display control ICs 132A, 132C that other electric elements (ICs, etc.) on the main control board 110 are not provided. The information display lamp 156 is also spaced so close to the main board side connector 161 that other electric elements (ICs, etc.) on the main control board 110 are not provided. If other electrical elements (ICs, etc.) are provided between the information display lamp 156 and the first and third display control ICs 132A, 132C or the main board side connector 161, it will be necessary to bypass them, making it difficult to efficiently form the conductor pattern.

[0077] As described above, the first display control IC 132A is used as both the segment driver of the setting display lamp 151 and the segment driver of the information display lamp 156. In order to efficiently form a conductor pattern on the printed circuit board 111, it is preferable to mount the information display lamp 156 near the setting display lamp 151. Therefore, the information display lamp 156 is disposed near the upper part of the setting display lamp 151. The information display lamp 156 is spaced from the setting display lamp 151 close enough that other electric elements (ICs, etc.) on the main control board 110 are not provided. However, in order to prevent numbers, etc. displayed by the setting display lamp 151 and the information display lamp 156 from being mistaken for a series of (five-digit) numbers, etc., it is preferable that the setting display lamp 151 and the information display lamp 156 are disposed so as not to be aligned horizontally.

[0078] The light emitted from each LED element 142 of the monitor lamp 141 is light with a relatively high brightness. Therefore, if the information display lamp 156 is arranged near the monitor lamp 141, the light emitted from each LED element 142 may reach the information display lamp 156, and the visibility of the information on the role ratio displayed by the information display lamp 156 may decrease. Therefore, the information display lamp 156 is arranged at a position away from the monitor lamp 141 at a distance such that the light from each LED element 142 does not reach the information display lamp 156. When other electric elements are arranged so as to block the light from each LED element 142, the distance between the information display lamp 156 and the monitor lamp 141 may be a distance that allows the light from each LED element 142 to reach the information display lamp 156. Note that the information display lamp 156 can also be arranged near the monitor lamp 141. In this case, the information on the role ratio displayed by the information display lamp 156 and the light emission state of each LED element 142 can be simultaneously visually recognized, so that the effort of the confirmation work can be reduced.

[0079] If the main board side connector 161 is disposed above the information display lamp 156, the front door cable harness 191 electrically connected to the main board side connector 161 may hang down and cover the front of the information display lamp 156, hindering visibility. Therefore, the main board side connector 161 is disposed near the left of the information display lamp 156, excluding the area above the information display lamp 156. For the same reason, other electrical connectors such as the reel connector 162, the auxiliary board connector 163, the setting change device connector 164, and the collator connector 165 are also disposed at positions excluding the area above the information display lamp 156. Furthermore, even if the electrical connectors such as the main board side connector 161 are disposed at positions excluding the area above the information display lamp 156, if there is a possibility that the cable harness will cover the front of the information display lamp 156 and hinder visibility, it is preferable to avoid such positions.

[0080] The left side portion of the main board case 210 where the main board side connector 161 is exposed is fixed to the bracket member 330 by the first and second case crimping members 340, 945. When attempting to break the upper case fixing portion 225a of the main board case 210 to release the locked state with the main body crimping member 340 (for example, when burning it off with a hot cutter), it is preferable that the information display lamp 156 inside the case is not broken by mistake. For this reason, the information display lamp 156 is disposed to the right of the upper case fixing portion 225a of the main board case 210 at a distance sufficient to allow other electrical elements (such as the main board side connector 161) in the main control board 110 to be provided.

[0081] As described above, the connector cover 246 is attached to the case lid 221 of the main board case 210 by the first cover crimping member 228. When attempting to break the connector cover 246 to release the engagement with the first cover crimping member 228 (for example, when burning it off with a hot cutter), it is preferable that the information display lamp 156 inside the case is not broken by mistake. For this reason, the information display lamp 156 is disposed at a position (apart from the first cover crimping member 228) that does not overlap with the first cover crimping attachment portion 229 of the case lid 221 when viewed from outside the case lid 221.

[0082] If the distance between the case cover 221 of the main board case 210 and the information display lamp 156 is too large, the visibility of the information display lamp 156 may be reduced depending on the viewing angle due to the influence of light reflection on the case cover 221. Therefore, as described above, the recess 237 is formed in the portion of the case cover 221 of the main board case 210 that overlaps with the information display lamp 156. This recess 237 can reduce the distance between the case cover 221 (recess 237) of the main board case 210 and the information display lamp 156, thereby suppressing the influence of light reflection on the case cover 221 and improving the visibility of the information display lamp 156. Also, as described above, the right wall portion 237d of the recess 237 is formed in a wall shape that is inclined to the right (farther from the hinge mechanisms 6a to 6c) as it moves forward. Thanks to this right wall portion 237d, even when the main board case 210 inside the housing 5 is viewed from the diagonally front right side on the side where the front door 2 opens, the information display lamp 156 can be viewed through the recess 237 (bottom 237e) of the case lid 221 without interfering with the ceiling portion of the case lid 221.

[0083] The distance between the bottom 237e of the recess 237 and the information display lamp 156 is preferably about 0.5 mm. In this way, by ensuring a gap between the case lid 221 (recess 237) of the main board case 210 and the information display lamp 156, it is possible to prevent actions such as pushing the case lid 221 from the outside to destroy the information display lamp 156 or actions to generate static electricity to destroy the information display lamp 156 while ensuring the visibility of the information display lamp 156. Furthermore, when the distance between the bottom 237e of the recess 237 and the information display lamp 156 is about 0.5 mm, it is preferable that the length and width of the bottom 237e is larger than the information display lamp 156 by about 1 mm on each side in order to ensure the visibility of the information display lamp 156.

[0084] In the main control device 100 configured as above, in order to check each part of the main control board 110 housed in the main board case 210, the front door 2 is opened and the main board case 210 attached in the housing 5 is viewed from the front or from the right diagonally forward. At this time, since the information display lamp 156 is arranged at a position that is not a sticker attachment area AS on the main control board 110 (printed board 111), the information on the role ratio displayed by the information display lamp 156 can be confirmed through the recess 237 (bottom 237e) of the case lid 221 without being blocked by the crimped use record sticker 248. Similarly, since the setting display lamp 151 is arranged at a position that is not a sticker attachment area AS on the main control board 110, the setting value displayed by the setting display lamp 151 can be confirmed through the case lid 221 without being blocked by the crimped use record sticker 248. Since monitor lamp 141 is also disposed in a position that is not in sticker affixing area AS on main control board 110, it is possible to check the light emission state of each LED element 142 constituting monitor lamp 141 through case lid 221 without being obstructed by crimped usage record sticker 248. Since control chip 121 is also disposed in a position that is not in sticker affixing area AS on main control board 110, it is possible to check through case lid 221 whether or not tampering has been performed on control chip 121 without being obstructed by crimped usage record sticker 248.

[0085] <Modification> In this embodiment, when a common main control board is used by a plurality of board manufacturers, a plurality of drawing sections corresponding to the number of board manufacturers may be provided on the main control board, and the drawing section on which the name of the board manufacturer who actually manufactured the main control board is printed may be left, and the other drawing sections may be removed from the main control board. For example, as shown in Fig. 14, when a common main control board 110A is used by two board manufacturers, two drawing sections 112A and 112B on which the names of the two board manufacturers are printed by a laser device or the like may be provided in the upper right portion of the printed circuit board 111.

[0086] The first and second drawing units 112A and 112B are arranged side by side along the outer periphery of the main control board 110A (printed board 111). The first and second drawing units 112A and 112B are connected to the printed board 111 via perforations, and are configured to be able to be individually removed from the printed board 111. As a result, of the first and second drawing units 112A and 112B, one drawing unit on which the name of the board manufacturer that actually manufactured the main control board 110A is printed can be left, and the other drawing unit can be removed from the main control board 110A. Therefore, even when a common main control board 110 is used by multiple (two) board manufacturers, it is possible to provide the main control board 110A with a drawing unit on which the name of the board manufacturer that manufactured the main control board 110A is printed.

[0087] The first and second drawing sections 112A and 112B are arranged at positions that are not in the sticker attachment area AS so that the board manufacturer name can be easily confirmed, as in the above-mentioned embodiment. The first and second drawing sections 112A and 112B are arranged at positions that are a distance away from the information display lamp 156 (and the setting display lamp 151) that does not impede the visibility of each drawing section when viewed from the outside of the case lid 221, as in the above-mentioned embodiment. In addition, when one of the first and second drawing sections 112A and 112B is left and the other is removed from the main control board 110, it is preferable that the first and second drawing sections 112A and 112B are arranged away from the information display lamp 156 (and the setting display lamp 151) in order to prevent the force acting during the removal from affecting the information display lamp 156 (and the setting display lamp 151).

[0088] Other characteristic configurations applicable to the above-mentioned main control boards 110 and 110A will be described below with additional reference to Figs. 15 to 27. Below, the characteristic configurations will be described using a main control board 410 that is different from the main control boards 110 and 110A. This main control board 410 can be used in the slot machine 1 in place of the main control boards 110 and 110A. The characteristic configurations of the main control board 410 described below can be similarly applied to the main control boards 110 and 110A. In addition, the above-mentioned configurations of the main control boards 110 and 110A can also be applied to the main control board 410.

[0089] In addition, the characteristic configuration described below is not limited to the slot machine of this embodiment, and can be combined with a pachinko game machine or other embodiments. In the following description, the directions indicated by the arrows in Figures 15 to 18 will be described as the up-down direction and the left-right direction, respectively. These directions are consistent with the up-down direction and the left-right direction indicated by the arrows in Figure 2.

[0090] <Aspects of lead wires of electrical elements mounted on a substrate> The main control board 410 is mainly composed of a printed circuit board 411 and a plurality of electric elements (electronic components) mounted on a surface portion (also referred to as a "first surface portion") FS of the printed circuit board 411. As shown in FIG. 15, a plurality of types of electric elements are mounted in a predetermined area (an area within a rectangular frame line FB10 shown by a solid line) on the surface portion FS of the printed circuit board 411. Specifically, as the plurality of types of electric elements, one IC driver 420A arranged in a horizontally placed state (a state in which the longitudinal direction of the component is parallel to the left-right direction), four resistors 430A arranged side by side in the left-right direction in a vertically placed state (a state in which the longitudinal direction of the component is parallel to the up-down direction), two resistors 430B arranged side by side in the up-down direction in the horizontally placed state, an IC socket 440A to which one control chip 450A is attached in the horizontally placed state, and four ceramic capacitors 460A arranged side by side in the left-right direction in the vertically placed state are respectively mounted.

[0091] In FIG. 15, five rectangular frame lines FB11 to FB15 are illustrated in two-dot chain lines. These rectangular frame lines FB11 to FB15 are frame lines illustrated for the sake of convenience in order to explain the area where the electric elements are mounted on the front surface FS of the printed circuit board 411, and are not actually formed on the front surface FS by printing or the like. The rectangular frame line FB11 indicates the area where the IC driver 420A is mounted, and the rectangular frame line FB12 indicates the area where the four resistors 430A are mounted. Similarly, the rectangular frame line FB13 indicates the area where the two resistors 430B are mounted, the rectangular frame line FB14 indicates the area where the control chip 450A is mounted via the IC socket 440A, and the rectangular frame line FB15 indicates the area where the four ceramic capacitors 460A are mounted.

[0092] The IC driver 420A includes a rectangular parallelepiped package section (also referred to as a "main body section") 421 and a plurality of lead wires (also referred to as "legs" or "terminals") 422 (in this example, 18 on each side of the package section 421 along the longitudinal direction, totaling 36) extending from the package section 421. Each lead wire 422 is formed so that its tip portion is thinner than its base portion (portion close to the package section 421), and is inserted into a plurality of predetermined through holes (not shown) formed in the printed circuit board 411 and soldered thereto. The resistors 430A and 430B include a cylindrical package section 431 and two lead wires 432 extending from both longitudinal ends of the package section 431, and each lead wire 432 is inserted into a plurality of predetermined through holes formed in the printed circuit board 411 and soldered thereto.

[0093] The control chip 450A includes a rectangular parallelepiped package portion 451 and a plurality of lead wires 452 (in this example, 36 on each side of the package portion 451 along the longitudinal direction, totaling 72) extending from the package portion 451. The IC socket 440A includes a receiving frame portion 441 that receives the package portion 451 of the control chip 450A and a plurality of lead wires 442 (see FIG. 16 ) extending from the receiving frame portion 441 (72, the same number as the lead wires 452 of the control chip 450A). Each lead wire 442 of the IC socket 440A is electrically connected to each lead wire 452 of the control chip 450A, and is inserted and soldered into a predetermined number of through holes formed in the printed circuit board 411. Ceramic capacitor 460A comprises an elliptical plate-shaped package portion 461 and two lead wires 462 extending from package portion 461, with each lead wire 462 being inserted into a predetermined number of through holes formed in printed circuit board 411 and soldered thereto.

[0094] Fig. 16 shows the main control board 410 as viewed from the front side from the back surface RS (also referred to as the "second surface") of the printed circuit board 411. The rectangular frame line FB20 shown by a solid line in Fig. 16 corresponds to the rectangular frame line FB10 shown in Fig. 15 (showing the same position and the same size range on the front surface FS and the back surface RS of the printed circuit board 411), and the five rectangular frame lines FB21 to FB25 shown by two-dot chain lines in Fig. 16 correspond to the five rectangular frame lines FB11 to FB15 shown in Fig. 15, respectively. The rectangular frame lines FB21 to FB25, like the rectangular frame lines FB11 to FB15, are frame lines shown for the sake of convenience in order to explain the area where the electric elements are mounted, and are not actually formed by printing or the like on the back surface RS.

[0095] 16, in the region within rectangular frame line FB20 of the back surface RS of the printed circuit board 411, a large number of lead wires are soldered to the printed circuit board 411. Specifically, a total of 32 lead wires 422 are soldered to the region within rectangular frame line FB21, and a total of 8 lead wires 432 are soldered to the region within rectangular frame line FB22. In addition, a total of 4 lead wires 432 are soldered to the region within rectangular frame line FB23, a total of 72 lead wires 442 are soldered to the region within rectangular frame line FB24, and a total of 8 lead wires 462 are soldered to the region within rectangular frame line FB25.

[0096] The 32 lead wires 422 in the area within the rectangular frame line FB21 and the 8 lead wires 432 in the area within the rectangular frame line FB22 are arranged relatively close to each other in the left-right direction on the back surface RS of the printed circuit board 411. The 32 lead wires 422 in the area within the rectangular frame line FB21 are divided into two rows, one above the other, and arranged so that the lead wires 422 in each row are aligned in the left-right direction, and the 8 lead wires 432 in the area within the rectangular frame line FB22 are also divided into two rows, one above the other, and arranged so that the lead wires 432 in each row are aligned in the left-right direction, and in this respect the two are similar. However, the arrangement pitch (the distance between adjacent lead wires 422) of the lead wires 422 aligned in the left-right direction in the area within the rectangular frame line FB21 is different from the arrangement pitch of the lead wires 432 aligned in the left-right direction in the area within the rectangular frame line FB22 (the former arrangement pitch is shorter than the latter arrangement pitch). In addition, the distance between the lead wire 422 located at the upper rightmost position in the area within the rectangular frame line FB21 and the lead wire 432 located at the upper leftmost position in the area within the rectangular frame line FB22 (also referred to as the "shortest distance between the lead wire 422 in the area within the rectangular frame line FB21 and the lead wire 432 in the area within the rectangular frame line FB22") is different from the left-right arrangement pitch of each lead wire 422 in the area within the rectangular frame line FB21 and the left-right arrangement pitch of each lead wire 432 in the area within the rectangular frame line FB22 (the former distance is longer than the latter two arrangement pitches).

[0097] Furthermore, the vertical positions of the lead wires 422 aligned in the left-right direction in the upper row in the area within the rectangular frame line FB21 are different from the vertical positions of the lead wires 432 aligned in the left-right direction in the upper row in the area within the rectangular frame line FB22 (the former are located higher than the latter). Similarly, the vertical positions of the lead wires 422 aligned in the left-right direction in the lower row in the area within the rectangular frame line FB21 are also different from the vertical positions of the lead wires 432 aligned in the left-right direction in the upper row in the area within the rectangular frame line FB22 (the former are located lower than the latter). In this way, based on the difference between the arrangement pitch of each lead wire 422 in the area within rectangular frame line FB21 and the arrangement pitch of each lead wire 432 in the area within rectangular frame line FB22, and the shortest distance between the lead wires 422 in the area within rectangular frame line FB21 and the lead wires 432 in the area within rectangular frame line FB22, and based on the difference between the up-down position of each lead wire 422 lined up in the left-right direction in each row in the area within rectangular frame line FB21 and the up-down position of each lead wire 432 lined up in the left-right direction in each row in the area within rectangular frame line FB22, it can be inferred that the type of electrical element having each lead wire 422 in the area within rectangular frame line FB21 is different from the type of electrical element having each lead wire 432 in the area within rectangular frame line FB22. By focusing on similar points, it can be inferred that the type of electrical element having each lead wire 432 in the area within rectangular frame line FB23 is different from the type of electrical element having each lead wire 422 in the area within rectangular frame line FB21 and the type of electrical element having each lead wire 442 in the area within rectangular frame line FB24, and that the type of electrical element having each lead wire 442 in the area within rectangular frame line FB24 is different from the type of electrical element having each lead wire 462 in the area within rectangular frame line FB25.

[0098] As described above, the 32 lead wires 422 in the region within the rectangular frame line FB21 are divided into two rows, one above the other, and 16 lead wires 422 in each row are arranged in a row in the left-right direction. The arrangement pitch of the lead wires 422 arranged in the left-right direction is significantly shorter than the distance between the two rows. In addition, (the tip of) each lead wire 422 protrudes linearly from the solder part (the part formed by the hardened solder material) SLR by a predetermined length from the back surface part RS in a vertical attitude to the back surface part RS. From the characteristics of such a state of each lead wire 422 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (attitude) of the lead wires, the protruding length of the lead wires, etc.), it is possible to guess that each lead wire 422 soldered in the region within the rectangular frame line FB21 is an IC driver (IC driver 420A in this example) arranged in a horizontal state among multiple types of electric elements, when viewed from the back surface part RS side of the printed circuit board 411.

[0099] As described above, the eight lead wires 432 in the region within the rectangular frame line FB22 are also divided into two rows, upper and lower, with four lead wires 432 in each row arranged in the left-right direction. The arrangement pitch of the lead wires 432 arranged in the left-right direction is shorter than the distance between the two rows, but longer than the arrangement pitch of the lead wires 422 arranged in the left-right direction in the region within the rectangular frame line FB21. From this, it can be inferred that the eight lead wires 432 soldered in the region within the rectangular frame line FB22 are paired (set) with each lead wire 432 in the upper row and each lead wire 432 in the lower row, and that the pair of upper and lower lead wires 432 may belong to one electric element. Based on this assumption, and focusing on the pair of upper and lower lead wires, the upper lead wire 432 extends a predetermined length from the back surface portion RS in a position where it bends diagonally downward and left from the solder portion SLR, and the lower lead wire 432 extends a predetermined length from the back surface portion RS in a position where it bends diagonally upward and left from the solder portion SLR. In other words, in a state where the back surface portion RS of the printed circuit board 411 is viewed from the front as shown in Fig. 16, the upper lead wire 432 is inclined to the left by an angle of about 10° with respect to an imaginary line segment (not shown) connecting the root portion of the upper lead wire 432 (the original portion extending from the solder portion SLR) and the root portion of the lower lead wire 432, and the lower lead wire 432 is also inclined to the left by an angle of about 10°.

[0100] From the characteristics of each lead wire 432 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (posture) of the lead wires, the way the lead wires are bent, etc.), it is possible to infer from the back surface RS side of the printed circuit board 411 that the eight lead wires 432 soldered in the area within the rectangular frame line FB22 are paired (set) with each lead wire 432 in the upper row and each lead wire 432 in the lower row, and that each pair of lead wires 432 is a resistor (resistor 430A in this example) arranged vertically among multiple types of electrical elements.

[0101] In addition, the four lead wires 432 in the region within the rectangular frame line FB23 are divided into two rows, one on the left and one on the right, and two lead wires 432 in each row are arranged in a vertical direction. The arrangement pitch of the lead wires 432 arranged in the vertical direction is shorter than the distance between the two rows, but is longer than the arrangement pitch of the lead wires 422 arranged in the horizontal direction in the region within the rectangular frame line FB21. From this, it can be inferred that the four lead wires 432 soldered in the region within the rectangular frame line FB23 are paired (set) with each lead wire 432 in the left row and each lead wire 432 in the right row, and that the pair of left and right lead wires 432 is one electric element. With this inference, focusing on the pair of left and right lead wires, the left lead wire 432 extends from the solder part SLR in a position bent diagonally downward to the right, and the two lead wires 432 in the right row extend from the solder part SLR in a position bent diagonally downward to the left. In other words, when the back surface RS of the printed circuit board 411 is viewed from the front, the left lead wire 432 is inclined downward at an angle of about 10° with respect to an imaginary line segment (not shown) connecting the base portion of the left lead wire 432 and the base portion of the right lead wire 432, and the right lead wire 432 is also inclined downward at an angle of about 10°.

[0102] From the characteristics of each lead wire 432 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the shape (posture) of the lead wires, the way the lead wires are bent, etc.), it is possible to infer from the back surface RS side of the printed circuit board 411 that the four lead wires 432 soldered in the area within the rectangular frame line FB23 are paired (set) with each lead wire 432 in the left column and each lead wire 432 in the right column, and that each pair of lead wires 432 is a resistor (resistor 430B in this example) arranged horizontally among multiple types of electrical elements.

[0103] The 72 lead wires 442 in the area within the rectangular frame line FB24 are divided into four rows, one above the other, with 18 lead wires 442 in each row arranged in the left-right direction. The row distance between the first and second rows from the top and the row distance between the third and fourth rows from the top are significantly shorter than the row distance between the second and third rows from the top. The lead wires 442 in the first row from the top and the lead wires 442 in the second row from the top are arranged alternately in the left-right direction, and the lead wires 442 in the third row from the top and the lead wires 442 in the fourth row from the top are also arranged alternately in the left-right direction. The arrangement pitch of the lead wires 442 arranged in the left-right direction in each row is significantly narrower than the row distance between the second and third rows from the top. The lead wires 442 (the tips of the lead wires 442) protrude linearly from the solder portion SLR by a predetermined length in a vertical position relative to the back surface portion RS. From the characteristics of each lead wire 422 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (posture) of the lead wires, the protruding length of the lead wires, etc.), it is possible to infer, when viewed from the back surface RS side of the printed circuit board 411, that each lead wire 442 soldered in the area within the rectangular frame line FB24 is an IC socket (IC socket 440A in this example) of multiple types of electrical elements, and that a control chip (control chip 450A in this example) is attached to the IC socket.

[0104] Moreover, the eight lead wires 462 in the region within the rectangular frame line FB25 are divided into two rows, one above the other, and four lead wires 462 in each row are arranged in a left-right direction. The arrangement pitch of the lead wires 462 arranged in the left-right direction is narrower than the distance between the two rows, but is wider than the arrangement pitch of the lead wires 422 arranged in the left-right direction in the region within the rectangular frame line FB21. From this, it can be inferred that the eight lead wires 462 soldered in the region within the rectangular frame line FB25 are paired (set) with each lead wire 462 in the upper row and each lead wire 462 in the lower row, and that the pair of upper and lower lead wires 462 is one electric element. With this inference, focusing on the pair of upper and lower lead wires, the upper lead wire 462 extends from the solder part SLR in a bent obliquely upward to the right, and the lower lead wire 462 extends from the solder part SLR in a bent obliquely downward to the left. In other words, when the back surface RS of the printed circuit board 411 is viewed from the front, the upper lead wire 462 is inclined to the right by an angle of approximately 160° and the lower lead wire 462 is inclined to the left by an angle of approximately 160° with respect to an imaginary line segment (not shown) connecting the base portion of the upper lead wire 462 and the base portion of the lower lead wire 462.

[0105] From the characteristics of each lead wire 462 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (posture) of the lead wires, the way the lead wires are bent, etc.), it is possible to infer from the back surface RS side of the printed circuit board 411 that the eight lead wires 462 soldered in the area within the rectangular frame line FB25 are paired (set) with each lead wire 462 in the upper row and each lead wire 462 in the lower row, and that each pair of lead wires 462 is a ceramic capacitor (ceramic capacitor 460A in this example) arranged vertically among multiple types of electrical elements.

[0106] 17, a plurality of types of electric elements are also mounted in another predetermined region (a region within a rectangular frame FB30 indicated by a solid line) on the front surface FS of the printed circuit board 411. Specifically, one information display lamp 470A arranged horizontally, one resistor array 480A arranged horizontally, and one LED element 490A arranged independently are mounted as the plurality of types of electric elements.

[0107] 17, three rectangular frame lines FB31 to FB33 are shown in two-dot chain lines. These rectangular frame lines FB31 to FB33 are frame lines shown for the sake of convenience in order to explain the area where electrical elements are mounted on the front surface FS of the printed circuit board 411, and are not actually formed on the front surface FS by printing or the like. The rectangular frame line FB31 indicates the area where the information display lamp 470A is mounted, the rectangular frame line FB32 indicates the area where the resistor array 480A is mounted, and the rectangular frame line FB33 indicates the area where the LED element 490A is mounted.

[0108] The information display lamp 470A includes a rectangular parallelepiped package section 471 (having a 7-segment LED on its front surface capable of displaying information such as a 4-digit number related to the role ratio) and a plurality of lead wires 472 (12 in this example, see FIG. 18) extending from the package section 471. Each lead wire 472 is inserted into a predetermined plurality of through holes (not shown) formed in the main control board 410 and soldered thereto. The resistor array 480A includes a rounded rectangular parallelepiped package section 481 and a plurality of lead wires 482 (9 in this example, see FIG. 18) extending from the package section 481, and each lead wire 482 is inserted into a predetermined plurality of through holes formed in the printed circuit board 411 and soldered thereto. The LED element 490A comprises a shotgun-shaped translucent package portion 491 and two lead wires 482 (see FIG. 18) extending from the package portion 491, and each lead wire 492 is inserted into and soldered to two predetermined through holes formed in the printed circuit board 411.

[0109] Fig. 18 shows the main control board 410 as viewed from the front side from the back surface RS side of the printed circuit board 411. A rectangular frame line FB40 shown by a solid line in Fig. 18 corresponds to a rectangular frame line FB30 shown in Fig. 17 (showing an area at the same position and of the same size on the front surface FS and back surface RS of the printed circuit board 411), and three rectangular frame lines FB41 to FB43 shown by two-dot chain lines in Fig. 18 correspond to three rectangular frame lines FB31 to FB33 shown in Fig. 17, respectively. The rectangular frame lines FB41 to FB43, like the rectangular frame lines FB31 to FB33, are frame lines illustrated for the sake of convenience in order to explain the area in which the electric elements are mounted, and are not actually formed by printing or the like on the back surface RS.

[0110] 18, in an area within a rectangular frame line FB40 on the back surface RS of the printed circuit board 411, a plurality of lead wires are soldered to the printed circuit board 411. Specifically, a total of 12 lead wires 472 are soldered to the area within a rectangular frame line FB41, a total of 9 lead wires 482 are soldered to the area within a rectangular frame line FB42, and a total of 2 lead wires 432 are soldered to the area within a rectangular frame line FB43.

[0111] The twelve lead wires 472 in the region within the rectangular frame line FB41 are divided into two rows, one above the other, and six lead wires 472 in each row are arranged in a row in the left-right direction. The arrangement pitch of the lead wires 472 arranged in the left-right direction is slightly narrower than the distance between the two rows. In addition, (the tip of) each lead wire 472 protrudes linearly from the solder part SLR by a predetermined length from the back surface part RS in a vertical position relative to the back surface part RS. From the characteristics of such a state of each lead wire 472 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (position) of the lead wires, the protruding length of the lead wires, etc.), it is possible to guess, when viewed from the back surface part RS side of the printed circuit board 411, that each lead wire 472 soldered in the region within the rectangular frame line FB41 is an information display lamp (information display lamp 470A in this example) arranged in a horizontal position among multiple types of electric elements.

[0112] The nine lead wires 482 in the region within the rectangular frame line FB42 are arranged in a row in the left-right direction. The arrangement pitch of the lead wires 482 is approximately the same as the arrangement pitch of the lead wires 472 arranged in the region within the rectangular frame line FB41 in the left-right direction. Of the nine lead wires 482, the three lead wires 482 at the left end and the three lead wires 482 at the right end protrude linearly from the solder part SLR by a predetermined length from the back surface part RS in a position perpendicular to the back surface part RS. On the other hand, of the nine lead wires 482, the three lead wires 482 in the center extend from the solder part SLR by a predetermined length from the back surface part RS in a position bent upward or downward. In detail, of the three lead wires 482 in the center, the two right lead wires 482 extend from the back surface portion RS in a posture in which they are bent downward from the solder portion SLR, and the one left lead wire 482 extends from the back surface portion RS in a posture in which they are bent upward from the solder portion SLR. From the characteristics of the state of each lead wire 482 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the shape (posture) of the lead wires, the bending of the lead wires, etc.), it is possible to guess, when viewed from the back surface portion RS of the printed circuit board 411, that the nine lead wires 482 soldered in the region within the rectangular frame line FB42 are a resistor array (resistor array 480A in this example) arranged in a horizontal state among multiple types of electric elements.

[0113] Moreover, the two lead wires 492 in the region within the rectangular frame line FB43 are arranged in a line in the vertical direction. The arrangement pitch of the lead wires 492 is approximately the same as the arrangement pitch of the lead wires 472 arranged in the horizontal direction in the region within the rectangular frame line FB41. The two lead wires 492 extend from the solder portion SLR by a predetermined length in a manner that bends to the right or downward. In detail, of the two lead wires 492, the upper lead wire 492 extends from the back surface portion RS in a manner that bends to the right from the solder portion SLR, and the lower lead wire 492 extends from the back surface portion RS in a manner that bends downward from the solder portion SLR. From the characteristics of each lead wire 492 (the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the shape (posture) of the lead wires, the way the lead wires are bent, etc.), it is possible to infer, when viewed from the back surface RS side of the printed circuit board 411, that the two lead wires 492 soldered in the area within the rectangular frame line FB43 are LED elements (LED element 490A in this example) among multiple types of electrical elements.

[0114] In this way, in the main control board 410, it is possible to estimate what type of electric element is arranged in what position and in what direction based on the state of each lead wire soldered to the printed circuit board 411 when viewed from the back surface RS side of the printed circuit board 411. Therefore, the arrangement of various electric elements mounted on the front surface side can be confirmed simply by viewing the main control board 410 from the back surface side and visually checking the state of each lead wire. Also, when inspecting the main control board 410 (inspection before putting the main control board 410 into the main board case or after removing it from the main board case), if a defect such as a crack in a solder part or the like is found in a predetermined area (position) of the back surface RS of the printed circuit board 411 when viewing the main control board 410 from the back surface side, it is possible to quickly estimate what type of electric element is causing the defect by visually checking the state of each lead wire in that area, and therefore work to correct the discovered defect (for example, replacing the electric element, etc.) can be smoothly performed. The lead wire configuration includes, but is not limited to, the number of lead wires, the arrangement pitch of the lead wires, the arrangement of the lead wires, the distance between the rows of the lead wires, the shape (posture) of the lead wires, the bending of the lead wires, and the protruding length of the lead wires. The lead wire configuration may include configurations related to the strength of the lead wires, such as the thickness and cross-sectional shape of the lead wires (the shape of the lead wires when viewed from the axial direction).

[0115] In addition, three or more electric elements of the same type (same kind and model) may be arranged and mounted on the front surface FS of the printed circuit board 411. In that case, even if the electric elements are the same type, the lead wires of the electric elements on the back surface RS of the printed circuit board 411 may be different. For example, when three or more IC drivers of the same type are arranged, the lead wires of the IC drivers arranged at both ends of the arrangement may be arranged to protrude linearly from the back surface RS by a predetermined length in a vertical position relative to the back surface RS, whereas the lead wires of the IC driver arranged in the center may be arranged to protrude from the back surface RS in a tilted position relative to the back surface RS. By taking such points into consideration, it becomes easier to guess what kind of electric elements are arranged in what position and in what direction based on the state of each lead wire soldered to the printed circuit board 411 when viewed from the back surface RS side of the printed circuit board 411.

[0116] <Relationship between the distance between the conductive layers of the board and the thickness of the gaming medal> FIG. 19 shows a schematic diagram of a layer structure (cross-sectional structure in the thickness direction of the board) of the printed circuit board 411. As shown in the figure, the printed circuit board 411 is a double-sided board (also called a "two-layer board") and is mainly composed of a board body 412 made of an insulating plate material, a first conductive layer 413 formed on a front surface 412a of the board body 412 of a thin film material having electrical conductivity such as copper foil, and a second conductive layer 414 formed on a back surface 412b of the board body 412 of a thin film material having electrical conductivity such as copper foil. The first conductive layer 413 constitutes a conductive pattern for the wiring circuit part, a land part for soldering formed around a through hole, and the like on the front surface 412a of the board body 412. Similarly, the second conductive layer 414 constitutes a conductive pattern for the wiring circuit part, a land part for soldering, and the like on the back surface 412b of the board body 412.

[0117] In addition, in Figs. 19 to 21, the thicknesses of the first conductive layer 413 and the second conductive layer 414 are illustrated much larger than their actual ratios in order to make them easier to see. In reality, a solder resist layer, a silk screen printing layer, and the like are also formed on the front surface 412a and the back surface 412b of the board main body 412, but these are not illustrated. In this embodiment, the front surface 412a of the board main body 412, the first conductive layer 413, the solder resist layer, the silk screen printing layer, and the like are collectively referred to as the front surface portion (first surface portion) FS of the printed circuit board 411 (or the main control board 410). Similarly, the back surface 412b of the board main body 412, the second conductive layer 414, the solder resist layer, the silk screen printing layer, and the like are collectively referred to as the back surface portion (second surface portion) RS of the printed circuit board 411 (or the main control board 410).

[0118] As shown in FIG. 19, the printed circuit board 411 is configured so that the interlayer distance (the shortest distance between the two layers) DS1 between the first conductive layer 413 and the second conductive layer 414 is greater than the thickness TH1 of one game medal ML (DS1>TH1). Therefore, as shown in FIG. 20, even if a situation occurs in which the side edge of the game medal ML abuts on the peripheral portion of the printed circuit board 411 during inspection of the main control board 410, the first conductive layer 413 and the second conductive layer 414 will not be conducted through the game medal ML. Therefore, it is possible to prevent the first conductive layer 413 and the second conductive layer 414 from being electrically short-circuited through the game medal ML and causing a malfunction in the electric element, etc. It is not often the case that the first conductive layer 413 and the second conductive layer 414 are formed to a position that reaches the peripheral portion of the printed circuit board 411. However, if the printed circuit board 411 is damaged and a part of it is missing or if a part of the printed circuit board 411 is removed (for example, if an unexpected crack occurs in the board when the above-mentioned drawing portion is removed), the first conductive layer 413 and the second conductive layer 414 may become exposed at the edge of the printed circuit board 411.

[0119] Also, as shown in FIG. 21, the interlayer distance DS1 between the first conductive layer 413 and the second conductive layer 414 in the printed circuit board 411 is only half or less than the radius of curvature CR1 of the pachinko ball PCB. Therefore, even if the surface (outer peripheral surface) of the pachinko ball PCB abuts against the edge of the printed circuit board 411 during inspection of the main control board 410, the first conductive layer 413 and the second conductive layer 414 will not be electrically connected through the pachinko ball PCB. Therefore, it is possible to prevent the first conductive layer 413 and the second conductive layer 414 from being electrically shorted through the pachinko ball PCB and causing a malfunction in the electrical element. Note that the same relationship may hold for medal components such as currency other than the game medal ML used in the game and spherical components other than the pachinko ball PCB, and the same effect can be obtained in such cases.

[0120] <Position and protruding height of lead wires of electrical elements mounted on the back side of the board> Fig. 22 illustrates various types of electric elements mounted on the front surface FS of the printed circuit board 411 of the main control board 410, and also illustrates the position and protruding height of the lead wires of each electric element on the rear surface side of the board. The illustrated electric elements are an IC driver 420B, a resistor 430C, an IC socket 440B to which a control chip 450B is attached, and a ceramic capacitor 460B. In Fig. 22, these electric elements are illustrated in a simplified manner. Also, the double-arrowed line DL1 shown in Fig. 22 indicates a direction perpendicular to the rear surface RS (front surface FS) of the printed circuit board 411.

[0121] In the IC driver 420B, each lead wire 422 (only two are shown) extending from the package part 421 passes through each predetermined through hole (not shown) formed in the printed circuit board 411, and protrudes from the back surface part RS of the printed circuit board 411 in a position that is approximately perpendicular to the back surface part RS (perpendicular (90°) or with an error angle from perpendicular within a few degrees (for example, 5°)). In other words, (the axis of) the lead wire 422 in the part protruding from the back surface part RS of the printed circuit board 411 is approximately perpendicular to the back surface part RS, and is approximately parallel to the direction perpendicular to the back surface part RS.

[0122] The resistor 430C has two lead wires 432 extending from both ends of the package part 431, which are bent and pass through predetermined through holes (not shown) formed in the printed circuit board 411, and protrude from the back surface part RS of the printed circuit board 411 at a predetermined inclination angle TA1 (for example, an angle within a range of 20° to 85°) with respect to a direction perpendicular to the back surface part RS. That is, the lead wires 432 protruding from the back surface part RS of the printed circuit board 411 are largely inclined with respect to a direction perpendicular to the back surface part RS.

[0123] In the IC socket 440B on which the control chip 450B is mounted, each lead wire 442 (only four are shown) extending from the receiving frame portion 441 passes through each predetermined through hole (not shown) formed in the printed circuit board 411 and protrudes from the back surface part RS of the printed circuit board 411 in a position approximately perpendicular to the back surface part RS. In other words, (the axis of) the lead wire 442 in the portion protruding from the back surface part RS of the printed circuit board 411 is approximately perpendicular to the back surface part RS and is approximately parallel to the direction perpendicular to the back surface part RS.

[0124] Ceramic capacitor 460B has two lead wires 462 each extending from package portion 461, which are bent and pass through predetermined through holes (not shown) formed in printed circuit board 411, and protrude from back surface portion RS of printed circuit board 411 at a predetermined inclination angle TA2 (for example, an angle within a range of 20° to 85°) with respect to a direction perpendicular to back surface portion RS. That is, the lead wires 462 protruding from back surface portion RS of printed circuit board 411 are largely inclined with respect to a direction perpendicular to back surface portion RS.

[0125] The lead wire 422 of IC driver 420B is strong because it is formed thicker and / or made of a high-strength material than the lead wire 432 of resistor 430C, the lead wire 442 of IC socket 440B, and the lead wire 462 of ceramic capacitor 460B. Also, the protruding height OH1 of lead wire 422 of IC driver 420B from the back surface RS of printed circuit board 411 (the shortest distance from the back surface RS to the tip of lead wire 422) is larger than the protruding height OH2 of lead wire 432 of resistor 430C, the protruding height OH3 of lead wire 442 of IC socket 440B, and the protruding height OH4 of lead wire 462 of ceramic capacitor 460B (in this example, OH1>OH2>OH3>OH4, but the magnitude relationship between OH2, OH3, and OH4 is not limited to this).

[0126] Therefore, when main control board 410 is placed on an inspection table or the like during inspection of main control board 410, lead wire 422 of IC driver 420B abuts against the inspection table before the lead wires of other electric elements, and it is possible to prevent the lead wires of other electric elements from contacting the inspection table. Also, when lead wire 422 of IC driver 420B abuts against the inspection table, IC driver 420B supports main control board 410, and main control board 410 can stand on its own. On the other hand, when lead wire 432 of resistor 430C or lead wire 462 of ceramic capacitor 460B, which are relatively weak in strength and have a portion protruding from rear surface portion RS of printed circuit board 411 that is largely inclined with respect to a direction perpendicular to rear surface portion RS, are configured to abut first, there is a risk that the lead wires (lead wire 432 or lead wire 462) will be deformed when abutted, causing a malfunction.

[0127] In addition, when the main control board 410 is accidentally dropped during inspection of the main control board 410, the lead wire 422 of the IC driver 420B is likely to come into contact with the inspection table or the floor before the lead wires of other electric elements. Therefore, while an impact is applied to the lead wire 422 of the IC driver 420B, the possibility of an impact being applied to the lead wires of other electric elements can be reduced. Since the lead wire 422 of the IC driver 420B has high strength, when an impact is applied, cracks or the like may occur in the part where the lead wire 422 is soldered, which has the advantage that it is easy to visually recognize the occurrence of a malfunction. On the other hand, even if an impact is applied to a lead wire with low strength, the lead wire will only be deformed and there is a low possibility that cracks or the like will occur in the soldered part or the like. Therefore, there is a risk that the occurrence of a malfunction will be overlooked.

[0128] In this embodiment, the lead wires of the IC driver are configured to come into contact with the inspection table or floor surface before the lead wires of the other electric elements, but the lead wires of the other electric elements may be configured to come into contact with the inspection table or floor surface before the lead wires of the other electric elements. In that case, it is preferable that the lead wires of the other electric elements have a higher strength than the lead wires of the other electric elements.

[0129] <Component names printed on the surface of the board> As shown in Fig. 23, a plurality of types of electric elements are mounted in a predetermined region (region within a rectangular frame FB50 shown by a solid line) on the front surface FS of the printed circuit board 411. The rectangular frame FB50 indicates the same region as the region indicated by the rectangular frame FB30 in Fig. 17, but Fig. 23 illustrates a greater number of types of electric elements mounted in the region than in Fig. 17. That is, in addition to the information display lamp 470A, resistor array 480A, and LED element 490A illustrated in the region within the rectangular frame FB30 in Fig. 17, an IIC driver 420C arranged in a horizontal position, a resistor 430D arranged in a horizontal position, a resistor 430E arranged in a vertical position, ceramic capacitors 460D and 460E arranged in a vertical position, and a transistor 495A are respectively mounted in the region within the rectangular frame FB50 in Fig. 23.

[0130] On the front surface FS of the printed circuit board 411, the names of components are printed in white by silk screen printing near each mounted electric element to make each electric element identifiable. Specifically, the names of components "R15", "SEG2", "RA3", and "IC11" are printed near the resistor 430D, the information display lamp 470A, the resistor array 480A, and the IIC driver 420C, respectively. In addition, the names of components "C27", "C29", "Q7", "R22", and "LED1" are printed near the ceramic capacitor 460D, the ceramic capacitor 460E, the transistor 495A, the resistor 430E, and the LED element 490A, respectively. The English letters in the names of each component indicate the type of electric element or the type of component of the electric element. For example, "R" indicates resistor, "SEG" indicates segment lamp, "RA" indicates resistor array, "IC" indicates integrated circuit, "C" indicates ceramic capacitor, "Q" indicates transistor, and "LED" indicates LED element, respectively. When multiple component names are printed near a certain electric element, the component name that is printed closest to the certain electric element and contains English characters that match the type of the certain electric element can basically be determined to be the component name of the certain electric element. The silkscreen printing that forms the component name and the component frame line described below is applied only to the front surface FS of the printed circuit board 411, and is not applied to the back surface RS. Furthermore, the component names are silkscreened so that they do not overlap each other.

[0131] FIG. 23 corresponds to the front view of the surface FS of the printed circuit board 411 (main control board 410). That is, FIG. 23 corresponds to the appearance when an operator such as a game parlor clerk looks at the main control board 410 installed inside the cabinet 5 from the front without tilting his / her head left or right with the front door 2 (see FIG. 6) of the slot machine 1 open. Therefore, in FIG. 23, the up, down, left, right directions from the operator's viewpoint (the up, down, left, right directions shown in parentheses on each arrow shown in FIG. 23) match the up, down, left, right directions in space (the up, down, left, right directions shown without parentheses on each arrow shown in FIG. 23). Here, the up, down, left, right directions from the operator's viewpoint are the directions in which the operator's eyes are lined up (left eye side is left) and the directions perpendicular to the left and right directions are up and down (the top of the operator's head is up).

[0132] As shown in FIG. 23, when the front surface FS of the printed circuit board 411 is viewed from the front, the component names "R15", "SEG2", "RA3", and "IC11" printed on the front surface FS are arranged in a left-to-right order. That is, these component names are arranged on the front surface FS in a horizontal writing manner (left-to-right writing) in which the characters are arranged from left to right when the front surface FS of the printed circuit board 411 is viewed from the front. In contrast, the component names "C27", "C29", "Q7", "R22", and "LED1" printed on the front surface FS are arranged in a bottom-to-top order. That is, these component names are arranged on the front surface FS in a horizontal writing manner (a manner in which the characters (character strings) in a left-to-right writing state are rotated 90 degrees to the left (counterclockwise)) in which the characters are arranged from bottom to top when the front surface FS of the printed circuit board 411 is viewed from the front. In this way, when the surface portion FS is viewed from the front, any part name printed on the surface portion FS is arranged in such an order that the characters constituting the part name are either arranged in an order from left to right, or in an order from bottom to top.

[0133] Therefore, when the front door 2 of the slot machine 1 is open and the operator looks at the main control board 410 from the front without tilting his / her head left or right, the part names "R15", "SEG2", "RA3", and "IC11" are arranged in a natural order that allows the operator to read the characters from left to right as seen by the operator (from the operator's viewpoint), as shown in FIG. 23. Therefore, these part names are easy to read and easy to recognize for the operator. In contrast, the part names "C27", "C29", "Q7", "R22", and "LED1" are arranged in a way that allows the operator to read the characters from bottom to top as seen by the operator (from the operator's viewpoint).

[0134] On the other hand, Fig. 24 corresponds to a case where the front door 2 of the slot machine 1 is open, the operator places his / her body on the open end side of the front door 2 or on the front side of the main control board 410 (the front side of the cabinet 5) and tilts his / her head (90°) to the left (the hinge end side of the front door 2) from the operator's viewpoint and looks at the main control board 410. Therefore, in Fig. 24, the up / down / left / right directions from the operator's viewpoint (the up / down / left / right directions shown in parentheses on each arrow shown in Fig. 24) do not match (are shifted by 90°) with the up / down / left / right directions in space (the up / down / left / right directions shown without parentheses on each arrow shown in Fig. 24).

[0135] When the front door 2 of the slot machine 1 is open and an operator places his / her body on the open end side of the front door 2 or in front of the main control board 410 and looks at the main control board 410 while tilting his / her head to the left from the operator's viewpoint, the characters constituting each of the part names "C27", "C29", "Q7", "R22", and "LED1" appear to be in a natural order read from the operator's viewpoint (from the operator's viewpoint) from left to right, as shown in Fig. 24. Therefore, these part names are easy for the operator to read and see.

[0136] The same applies when the main control board 410 is installed on the rear side of the front door 2 so as to face the housing 5. That is, when the front door 2 is open and the worker looks at the main control board 410 installed on the rear side of the front door 2 from the front without tilting his / her head left or right, the part names "R15", "SEG2", "RA3", and "IC11" appear to be arranged in a natural order in which the characters constituting those part names are read from left to right from the worker's viewpoint. When the front door 2 is open and the worker places his / her body on the front side of the main control board 410 (the front side of the rear side of the front door 2) and looks at the main control board 410 installed on the rear side of the front door 2 while tilting his / her head to the left (the open end side of the front door 2) from the worker's viewpoint, the part names "C27", "C29", "Q7", "R22", and "LED1" appear to be arranged in a natural order in which the characters constituting those part names are read from left to right from the worker's viewpoint.

[0137] When main control board 410 is installed on the rear side of front door 2 so as to face housing 5, an operator may place his / her body on the open end side of front door 2 with front door 2 open and tilt his / her head to the right (toward the hinge end of front door 2) from the operator's viewpoint to look at main control board 410. In that case, the characters constituting each part name, "C27", "C29", "Q7", "R22", and "LED1", appear to be arranged upside down and in order from right to left from the operator's viewpoint.

[0138] Therefore, when the main control board 410 is installed on the back side of the front door 2, if the worker wants to check the part name, the worker can avoid the above-mentioned view (the view of tilting the head toward the hinge end of the front door 2) to avoid the occurrence of such a situation. The sub-control board in the slot machine 1 is installed on the back side of the front door 2 so as to face the cabinet 5, and the arrangement of the characters constituting each part name is the same as that of the main control board 410. Therefore, the same situation as when the main control board 410 is installed on the back side of the front door 2 may occur. However, by utilizing the occurrence of such a situation, it is possible to distinguish whether the board that the worker is looking at by tilting his / her head toward the hinge end of the front door 2 is the main control board 410 installed inside the cabinet 5 or the sub-control board installed on the back side of the front door 2, based on the arrangement of the characters constituting the part name.

[0139] As shown in FIG. 23, characters indicating the manufacturer name, board name (number), etc. (in this example, "NAMAE BANGOU33-X") are written in an area within a rectangular frame line FB50 on the surface portion FS of the printed circuit board 411. Unlike the component names, these characters (also referred to as "board name, etc. characters") are not silk-screened, but are formed of copper foil or the like that constitutes the conductive layer. Therefore, they are less noticeable than the component names silk-screened in white. On the other hand, if an attempt is made to scrape off the board name, etc. characters, the surface portion FS of the printed circuit board 411 will be scratched, making them more noticeable. Therefore, there is an effect of deterring the fraudulent act of scraping off the board name, etc. characters.

[0140] Each component name is printed at a position excluding the land portion around the through-hole formed in the printed circuit board 411 and the solder portion formed on the through-hole and the land portion by soldering so as not to overlap these portions. For example, as shown in FIG. 25(A), when the component name "LED" is printed near the through-hole (not shown), it is printed so as not to overlap the land portion LND and the solder portion SLR. This makes it possible to clearly visually recognize the component name. In contrast, as shown in FIG. 25(B), if the component name "LED" is printed so as to overlap partly with the land portion LND and the solder portion SLR, there is a risk that part of the character is missing, and it becomes impossible to distinguish that the printed character is "LED". That is, in the example shown in FIG. 25(B), there is a risk that the "L" constituting the component name "LED" is mistakenly recognized as "I", and the "E" is mistakenly recognized as "F". Even when the component name is printed so as to overlap partly with the land portion LND and the solder portion SLR, it is preferable to limit the overlap to a degree that does not cause such a mistaken recognition. Here, the part name "LED" has been used as an example for explanation, but the same applies to any other part name.

[0141] <Component borders printed on the surface of the board> 23, in the area within a rectangular frame FB50 on the front surface FS of the printed circuit board 411, component frame lines corresponding to the outline shapes of the mounted electric elements are printed in white by silk screen printing. Specifically, a component frame line PB1 for the resistor 430D, a component frame line PB2 for the resistor 430E, a component frame line PB3 for the ceramic capacitor 460D, a component frame line PB4 for the ceramic capacitor 460E, a component frame line PB5 for the transistor 495A, a component frame line PB6 for the resistor array 480A, and a component frame line PB7 for the LED element 490A are printed. A component frame line for the information display lamp 470A and a component frame line for the IIC driver 420C are also printed but are not shown.

[0142] Each component frame line is printed at a position excluding the land portion around the through hole formed in the printed circuit board 411 and the solder portion formed on the through hole and the land portion by soldering so as not to overlap these portions. For example, as shown in FIG. 26, in the case where the land portion LND and the solder portion SLR to which the lead wire (not shown) of the transistor 495A is soldered are located near the portion where the transistor 495A is mounted, the component frame line PB5 for the transistor 495A is printed so as not to overlap the land portion LND and the solder portion SLR. Here, the component frame line PB5 for the transistor 495A is exemplified and described, but the same applies to any other component frame line. Note that each component frame line is preferably printed at a distance from the land portion LND so as not to contact the land portion LND, as in the component frame line PB5 shown in FIG. 26. This makes it possible to prevent the paint for silk printing from adhering to the land portion LND and the through hole portion.

[0143] <Ensuring visibility of information display lamps> As shown in FIG. 23, the LED element 490A is mounted at a position relatively close to the information display lamp 470A. Also, as shown in FIG. 27, when the surface portion FS of the printed circuit board 411 is used as a height reference, the height HT1 of the information display lamp 470A is higher than the height HT2 of the LED element 490A (HT1>HT2). Also, the light emitted by the LED element 490A is light with a relatively high brightness. Therefore, there is a risk that the light emitted from the LED element 490A reaches the information display lamp 470A and is reflected by the side surface of the package part 471 of the information display lamp 470A, thereby reducing the visibility of the information displayed by the information display lamp 470A. Therefore, in the information display lamp 470A, the side surface of the package part 471 is subjected to matte printing (for example, white color) to make it difficult to reflect light. Specifically, the reflectance of light on the side surface of the package part 471 is configured to be lower than the reflectance of light on the lead wire 472 of the information display lamp 470A. This makes it possible to ensure the visibility of the information displayed by information display lamp 1070 even when LED element 490A emits light. When mounting the setting display lamp on front surface FS of printed circuit board 411, it is preferable to apply a similar treatment to the side surface of the package part of the setting display lamp.

[0144] In addition, it is preferable that no components higher than the information display lamp 470A and the control chip 450A are arranged around the information display lamp 470A and the control chip 450A. Specifically, the height of the components (referred to as "closest components") arranged closest to the information display lamp 470A and the control chip 450A is preferably such that the components do not come into contact with the information display lamp 470A and the control chip 450A even if the components are tilted for some reason. More preferably, the height of the closest components is preferably such that the main body does not hide all or part of the display of the information display lamp 470A or the description of the model sticker (a sticker indicating the model name of the slot machine in which the control chip 450A is mounted) attached to the package of the control chip 450A even if the components are tilted.

[0145] In addition, when placing a tall component near the information display lamp 470A and the control chip 450A, it is preferable to place a DIP (dual in-line package) type IC chip or a lead component whose main body abuts against the substrate (hereinafter referred to as a "substrate abutting component") between the component and the information display lamp 470A or the control chip 450A. Here, a "tall component (hereinafter also referred to as a "tall component")" refers to a lead component having a component height that, if the component is tilted for some reason, hides all or part of the display of the information display lamp 470A or the description on the model sticker affixed to the control chip 450A. The DIP type IC chip and substrate abutting component described above are extremely unlikely to tilt. Therefore, by arranging the components as described above, even if the tall component tilts, it will be prevented from tilting further by abutting against the DIP-type IC chip or the board abutment component, so that it is possible to prevent the tall component from obscuring all or part of the display of the information display lamp 470A or the information on the model sticker affixed to the control chip 450A.

[0146] <Configuration of sub-control device and power supply unit> Next, the configurations of the sub-control device 500 and the power supply device 55 according to this embodiment will be described with reference to FIG. 28 and FIG.

[0147] (Configuration of the sub-controller) 4, the sub-controller 500 is attached to the upper side of the reel window W behind the front door 2. Similar to the main controller 100, the sub-controller 500 is configured by accommodating a sub-control board 502 on which various components are mounted in a sub-board case 501 consisting of a case body and a case lid.

[0148] FIG. 28 shows a front view of the slot machine 1 viewed from the rear to the front with the sub-control device 500 installed on the front door 2 and the case lid of the sub-substrate case 501 removed. The up, down, left, and right directions shown by the arrows in FIG. 28 correspond to the directions of the arrows in FIG. 2 and FIG. 4. As shown in FIG. 28, the sub-control substrate 502 is composed of a sub-main substrate 510 and a sub-sub substrate 520, and when the sub-control device 500 is installed on the front door 2, the component mounting surfaces of the sub-main substrate 510 and the sub-sub substrate 520 face backward and are aligned in the up and down direction. In addition, the component occupancy rate of the sub-control substrate 502 (the ratio of the total area of ​​all mounted components (the total area of ​​each component when the component mounting surface of the substrate is viewed in plan) to the area of ​​the substrate) is about 50%.

[0149] The sub-main board 510 is rectangular in shape, and various electronic components (electronic elements) including integrated circuits such as a sub-CPU 511, a sub-ROM 512, a sub-RAM 513, and a three-terminal regulator 514, active elements such as transistors and LEDs, and passive elements such as resistors, ceramic capacitors, electrolytic capacitors, and toroidal coils are mounted on its component mounting surface. A connector 515 is disposed at the center of the left edge of the sub-main board 510, and is electrically connected to a connector 528 of the sub-sub board 520. Furthermore, a plurality of electrical connectors 516, 516, ... are disposed on the upper edge, right edge, and lower edge of the sub-main board 510, respectively.

[0150] The sub-substrate 520 is rectangular in shape, and on its component mounting surface, various electronic components (electronic elements) including an image processing CPU 521, an image ROM 522, a VIDEORAM 523, an audio processing substrate 524 on which an audio ROM storing audio data and an audio source IC are mounted, integrated circuits such as a logic IC 525, active elements such as transistors and LEDs, and passive elements such as resistors, ceramic capacitors, electrolytic capacitors, and toroidal coils, as well as electrical components such as a connector 526 and a slide switch 527 are mounted. A connector 528 electrically connected to the connector 515 of the sub-main substrate 510 is disposed at the center of the right edge of the sub-substrate 520. The connector 515 of the sub-main substrate 510 and the connector 528 of the sub-substrate 520 are connected to each other, thereby electrically connecting the sub-main substrate 510 and the sub-substrate 520.

[0151] (Power supply configuration) The power supply device 55 converts the AC power input from the outside into a direct current, converts it into a predetermined voltage value (for example, +5V, +12V, etc.), and outputs it to various devices installed inside the housing 5. The power supply device 55 has a shape of a substantially rectangular parallelepiped, and is attached in the lower part (on the bottom plate 5d) of the housing 5 with the left side surface of the power supply device 55 abutting against the left side plate 5a of the housing 5 as shown in FIG. 3. The front of the power supply device 55 is a resin front panel provided with a power switch for turning on the power of the slot machine 1, and the top, bottom, back, left and right sides are formed of metal plates. In addition, the metal plates on the top, bottom, back and left sides are integrally molded as a single member, and the above-mentioned front panel is attached to the front of this member. Furthermore, the metal plate on the right side is configured to be removable, and by removing the metal plate on the right side, the power supply board 550 described later can be accommodated inside the power supply device 55.

[0152] FIG. 29 shows a front view of the slot machine 1 viewed from right to left with the power supply device 55 installed on the bottom plate 5d in the housing 5 and with the metal plate on the right side of the power supply device 55 removed. The up-down, front-rear and rear directions shown by the arrows in FIG. 29 correspond to the directions of the arrows in FIG. 2. As shown in FIG. 29, a power supply board 550 is provided inside the power supply device 55, and when the power supply device 55 is installed in the housing 5, the component mounting surface of the power supply board 550 faces rightward and is aligned in the up-down direction. The component occupancy rate of the power supply board 550 is about 50%.

[0153] The power supply board 550 is rectangular in shape, and various electronic components (electronic elements) including integrated circuits such as logic IC 551 and three-terminal regulators 552a, 552b, and 552c, active elements such as transistors and LEDs, and passive elements such as resistors, ceramic capacitors, electrolytic capacitors, toroidal coils, and varistors are mounted on the component mounting surface. Here, the sizes of the electrolytic capacitors mounted on the various boards (main control board 111, sub-control board 502, power supply board 550) of this embodiment are divided into three types: small electrolytic capacitors with a rated voltage of 50V and a capacity of up to 270μF (external dimensions of diameter 8mm, height 20mm), medium-sized electrolytic capacitors with a rated voltage of 50V and a capacity of more than 270μF and up to 1000μF (external dimensions of diameter 12mm, height 25mm), and large electrolytic capacitors with a rated voltage of 50V and a capacity of more than 1000μF and up to 4700μF (external dimensions of diameter 18mm, height 40mm). Further, provided on the upper edge of the power supply board 550 are a power supply input connector 553 for inputting AC power from the outside, and power supply output connectors 554a, 554b, and 554c for outputting power supplies of various voltages generated in the power supply board 550 to various devices installed inside the housing 5. Further, provided on the front edge of the power supply board 550 is a panel connector 555 for electrically connecting to a power switch (not shown) attached to the front panel 55a.

[0154] An opening is provided on the top surface 55b of the power supply device 55 so that connectors of various power cables can be fitted to the power input connector 553 and the power output connectors 554a, 554b, and 554c. A number of round heat dissipation holes (not shown) are provided on the bottom surface 55c of the power supply device 55 to dissipate heat inside the power supply device 55 to the outside. A spacer SP is attached to the bottom surface 55c to provide a gap TH2 between the bottom plate 5d of the housing 5 and the bottom surface 55c in order to release the heat dissipated from these heat dissipation holes to the outside.

[0155] The size of this gap TH2 (the distance between the bottom plate 5d and the bottom surface 55c) is larger than the thickness of one game medal and smaller than the thickness of two game medals. In this way, by providing the gap TH2 between the bottom plate 5d and the bottom surface 55c, heat generated inside the power supply device 55 is released into the housing 5 through the bottom surface 55c, so that the various components mounted on the power supply board 550 are less likely to be adversely affected by a rise in temperature inside the power supply device 55. In addition, since the size of the gap TH2 is larger than the thickness of one game medal, it is possible to eliminate the risk of a game medal being caught in this gap while securing a gap between the bottom plate 5d and the bottom surface 55c. For example, if the size of the gap TH2 is made to be approximately the same dimension as the thickness of one game medal, there is a risk that a game medal spilled from the hopper 51 of the medal payout device 50 will be caught between the bottom plate 5d and the bottom surface 55c, making it difficult to remove the caught game medal.

[0156] Moreover, by making the size of the gap TH2 larger than the thickness of one game medal, even if the game medal gets stuck between the bottom plate 5d and the bottom surface 55c, it can be easily removed. In addition, by making the size of the gap TH2 smaller than the thickness of two game medals, it is possible to eliminate the risk that two game medals will be stuck between the bottom plate 5d and the bottom surface 55c in a stacked state, and it is also possible to reduce the risk that foreign objects other than game medals will get stuck between the bottom plate 5d and the bottom surface 55c. Furthermore, for example, when the slot machine 1 is transported, even if a strong impact is applied in the vertical direction when the slot machine 1 is lowered from the bed of a transport truck to the ground, since a gap is provided between the bottom plate 5d and the bottom surface 55c, there is a room for the bottom surface 55c of the power supply device 55 to bend, and it is expected that the impact transmitted to the power supply board 550 will be mitigated by the bending of the bottom surface 55c.

[0157] (Layout of components mounted on the sub-control board and power supply board) Next, the arrangement of various components mounted on sub-control board 502 and power supply board 550 will be described with reference to Figs. 30 to 32. Fig. 30 shows a state in which a component having a lead extending from the component body and soldered to the board with the component body floating above the surface of the board (i.e., with a gap between the component body and the board surface) has tilted due to some cause. Here, possible causes of the component tilting include, for example, an impact being applied when slot machine 1 is lowered to the ground, being pushed by a wire inserted through a gap in the board case due to fraud, or an operator accidentally touching a component on the board when attaching the board to the board case.

[0158] Figures 30(a-1) to (a-3) show a state in which the components attached to area BS1 of sub-substrate 520 shown in Figure 28 are tilted. Here, Figure 30(a-1) shows the state when area BS1 is viewed from right to left, Figure 30(a-2) shows the state when area BS1 is viewed from bottom to top (the direction of arrow A in Figure 30(a-1)), and Figure 30(a-3) shows the state when area BS1 is viewed from rear to front (the direction of arrow B in Figure 30(a-1)). The directions of the arrows shown in Figures 30(a-1) to (a-3) correspond to the directions of the arrows shown in Figure 2.

[0159] In the area BS1, the bodies of LEDLs1 and Ls2 are mounted side by side in the left-right direction while floating above the surface of the sub-substrate 520, and the resistor Rs1 is mounted below them. Fig. 30 (a-1) to (a-3) show the state in which LEDLs1 is tilted downward. At this time, the body (light emitting part) of LEDLs1 abuts on the body part of the resistor Rs1, so the lead wire extending from the body of LEDLs1 does not contact the lead wire of the resistor Rs1. Here, for example, when silk-printing the unique part numbers given to various parts on the board, it is preferable to perform the silk-printing at a position where the part numbers displayed by the silk-printing are not hidden by the tilted parts. For example, if the part number of LEDLs1 is "D1" and the part number of LEDLs2 is "D2", LEDLs1 and Ls2 are tilted in the up-down direction as shown in Fig. 30 (a-3), so it is preferable to perform the silk-printing SLK representing these part numbers on the right or left side of LEDLs1 and Ls2. Alternatively, when printing the component number on the top and bottom of LEDLs1 and Ls2, it is preferable to print the silkscreen at a position away from LEDLs1 and Ls2 (for example, a position away from LEDLs1 and Ls2 by a distance equal to the length of the lead wire floating above the board plus the height of the component body) so that the silkscreened component number is not hidden even when LEDLs1 and Ls2 are tilted.

[0160] 30(b-1) to (b-3) show a state in which the components attached to the area BP1 of the power supply board 550 shown in FIG. 29 are tilted. Here, FIG. 30(b-1) shows the state when the area BP1 is viewed in a direction from the front to the rear, FIG. 30(b-2) shows the state when the area BP1 is viewed in a direction from the bottom to the top (the direction of the arrow A in FIG. 30(b-1)), and FIG. 30(b-3) shows the state when the area BP1 is viewed in a direction from the right to the left (the direction of the arrow B in FIG. 30(b-1)). The directions of the arrows shown in FIG. 30(b-1) to (b-3) are also in accordance with the directions of the arrows shown in FIG. 2.

[0161] In the region BP1, the body of the medium-sized electrolytic capacitor Cp1 is mounted in a state where it is floating above the surface of the power supply board 550, and the resistor Rp1 is mounted below it, and Fig. 30 (b-1) to (b-3) show the state where the medium-sized electrolytic capacitor Cp1 is tilted downward. At this time, the body of the medium-sized electrolytic capacitor Cp1 abuts against the body of the resistor Rp1, so that the lead wire extending from the body of the medium-sized electrolytic capacitor Cp1 does not contact the lead wire of the resistor Rp1. Here, for example, if the medium-sized electrolytic capacitor Cp1 and the resistor Rp1 are mounted near the lower edge of the power supply board 550, the medium-sized electrolytic capacitor Cp1 may be mounted so that the top of the medium-sized electrolytic capacitor Cp1 does not protrude from the lower edge of the board when the medium-sized electrolytic capacitor Cp1 is tilted downward and abuts against the body of the resistor Rp1.

[0162] 30(c-1) to (c-3) show a state in which the components attached to the area BP2 of the power supply board 550 shown in FIG. 29 are tilted. Here, FIG. 30(c-1) shows the state when the area BP2 is viewed in a direction from the front to the rear, FIG. 30(c-2) shows the state when the area BP2 is viewed in a direction from the top to the bottom (the direction of the arrow A in FIG. 30(c-1)), and FIG. 30(c-3) shows the state when the area BP2 is viewed in a direction from the right to the left (the direction of the arrow B in FIG. 30(c-1)). The directions of the arrows shown in FIG. 30(c-1) to (c-3) are also in accordance with the directions of the arrows shown in FIG. 2.

[0163] 30(c-1) to (c-3) show a state in which the fuse Fp1 is tilted upward. At this time, the body of the fuse Fp1 abuts against the body of the ceramic capacitor Cp2, so that the lead wires extending from the body of the fuse Fp1 do not come into contact with the lead wires of the ceramic capacitor Cp2.

[0164] As shown in Fig. 30(c-2), the lead wire of the ceramic capacitor Cp2 has a roughly S-shaped bent portion bd (encircled by a dashed line in the figure) located near the component body. This means that even if a force is applied to the ceramic capacitor Cp2 in the vertical direction, the force is absorbed by the bent portion bd, and it is expected that the force applied to the lead wire located near the board surface will be reduced. This makes the lead wire less likely to break, making it less likely that the component will malfunction.

[0165] In this embodiment, even if a component mounted above the board tilts for some reason, the body of the tilted component abuts against the body of another component or the surface of the board, preventing further tilting, so that the lead wires of the components do not come into contact with each other. Therefore, even if a component mounted above the board tilts, the lead wires of the component do not come into contact with the lead wires of a nearby component and cause a short circuit, making it difficult for the components mounted on the board to malfunction. In other words, by making it difficult for components to malfunction, the risk of the gaming machine stopping can be reduced, allowing players to play smoothly.

[0166] Here, it is sufficient to provide a space between components so that a certain component does not come into contact with other components around it even if it is tilted, but since the space in which the device can be installed inside the housing 5 is limited, it is difficult to increase the size of the board. In addition, if a connector is arranged on the board, it is desirable not to arrange components around the connector because there is a risk that the component will be damaged when attaching and detaching the harness to the connector if a component is arranged nearby. Furthermore, for LEDs and fuses, space is also required to ensure the visibility of the light-emitting parts and fuses. For these reasons, it is difficult to ensure the arrangement space of each component so that the component does not come into contact with other components around it even if it is tilted. Therefore, in such a case, the lead wires of each component are prevented from coming into contact with each other by arranging the main body of the component so that it comes into contact with the main body or lead wire of the other components around it when the component is tilted.

[0167] Next, Figure 31 shows a component having lead wires extending from the component body, which is soldered to the board with the component body floating above the surface of the board (i.e., with a gap between the component body and the board surface), and in which the component mounted near the edge of the board has become tilted for some reason.

[0168] Figures 31(a-1) to (a-3) show a state in which the components attached to area BS2 of sub-substrate 520 shown in Figure 28 are tilted. Here, Figure 31(a-1) shows the state when area BS2 is viewed from right to left, Figure 31(a-2) shows the state when area BS2 is viewed from bottom to top (the direction of arrow A in Figure 31(a-1)), and Figure 31(a-3) shows the state when area BS2 is viewed from rear to front (the direction of arrow B in Figure 31(a-1)). The directions of the arrows shown in Figures 31(a-1) to (a-3) correspond to the directions of the arrows shown in Figure 2.

[0169] In region BS2, the body of medium-sized electrolytic capacitor Cs1 is mounted in a state where it is floating above the surface of sub-substrate 520, and Figures 31(a-1) to (a-3) show the medium-sized electrolytic capacitor Cs1 tilted downward. Here, the tilt of medium-sized electrolytic capacitor Cs1 stops when the peripheral part of the bottom of the body abuts against the surface of the substrate (see the part surrounded by the dashed line in the figure), but at this time, medium-sized electrolytic capacitor Cs1 is mounted in a position where the body of medium-sized electrolytic capacitor Cs1 (more specifically, the head of the body) does not protrude from the peripheral edge of the substrate (see the dashed line in the figure).

[0170] Figures 31(b-1) to (b-3) show a state in which the components attached to area BP2 of power supply board 550 shown in Figure 29 are tilted. Here, Figure 31(b-1) shows the state when area BP2 is viewed from the front to the rear, Figure 31(b-2) shows the state when area BP2 is viewed from below to above (the direction of arrow A in Figure 31(b-1)), and Figure 31(b-3) shows the state when area BP2 is viewed from the right to the left (the direction of arrow B in Figure 31(b-1)). The directions of the arrows shown in Figures 31(b-1) to (b-3) are also in accordance with the directions of the arrows shown in Figure 2.

[0171] As described above, in the region BP2, the fuse Fp1 body is arranged in a state where it is floating above the surface of the power supply board 550, and the ceramic capacitor Cp2 is arranged above it. And Fig. 31 (b-1) to (b-3) show the fuse Fp1 in a state where it is tilted downward. At this time, the inclination of the fuse Fp1 body is stopped when the side of the fuse Fp1 abuts against the surface of the board (see the part surrounded by the dashed line in the figure), but the fuse Fp1 is mounted in a position where the fuse Fp1 body (more specifically, the head of the fuse Fp1 body) does not protrude from the periphery of the board at this time (see the dashed line in the figure). In this way, when the fuse Fp1 is tilted upward as described above, the lead wire of the fuse Fp1 does not come into contact with the lead wire of the ceramic capacitor Cp1, and when the fuse Fp1 is tilted downward, the fuse Fp1 is mounted in a position where the fuse Fp1 body does not protrude from the periphery of the board.

[0172] Figures 31(c-1) to (c-3) show a state in which the components attached to the region BP3 of the power supply board 550 shown in Figure 29 are tilted. Here, Figure 31(c-1) shows the state when the region BP3 is viewed in a direction from the front to the rear, Figure 31(c-2) shows the state when the region BP3 is viewed in a direction from the bottom to the top (the direction of arrow A in Figure 31(c-1)), and Figure 31(c-3) shows the state when the region BP3 is viewed in a direction from the right to the left (the direction of arrow B in Figure 31(c-1)). The directions of the arrows shown in Figures 31(c-1) to (c-3) are also in accordance with the directions of the arrows shown in Figure 2.

[0173] In region BP3, the bodies of LEDLp1 and Lp2 are mounted side by side in the left-right direction while floating above the surface of power supply board 550, and resistor Rp2 is mounted above LEDLp1, and Fig. 31(c-1) to (c-3) show a state in which LEDLp1 is tilted downward. At this time, the tilt of the body (light-emitting part) of LEDLs1 stops when the bottom peripheral part of the body abuts against the surface of the board (see the part surrounded by the dashed line in the figure), but LEDLp1 is mounted at a position such that the body of LEDLp1 (more specifically, the head of the body) does not protrude from the peripheral part of the board at this time (see the dashed line in the figure).

[0174] In this way, in this embodiment, even if a component mounted floating from the board tilts for some reason, the body of the tilted component does not abut against the surface of the board, and a part of the component does not protrude outside the periphery of the board. Therefore, even if a component mounted floating from the board tilts, there is no risk of the component hitting the wall of the board case or the device body that houses the board and being damaged. Therefore, by making it difficult for the components mounted on the board to malfunction, the risk of the gaming machine stopping operation can be reduced, and players can play smoothly.

[0175] Here, it would be good if there was enough space between the mounted components so that even if a component tilts, it will not come into contact with other surrounding components, but due to the reasons mentioned above, it is difficult to ensure that each mounted component has enough space to avoid contact with surrounding mounted components even if it tilts, and especially when the component occupancy rate on the board is high, there are cases where the mounted components have to be placed near the edge of the board. Therefore, even in such cases, a component is placed so that part of its body does not protrude beyond the edge of the board when it tilts.

[0176] Next, the directions of the multiple lead wires extending from the components mounted on the board will be described with reference to Fig. 32 and Fig. 33. First, Fig. 32(a-1) and (a-2) show the mounting state of the components attached to the area BP4 of the power supply board 550 shown in Fig. 29. Here, Fig. 32(a-1) shows the state when the area BP4 is viewed from the front to the rear, and Fig. 32(a-2) shows the state when the area BP4 is viewed from the right to the left (the direction of the arrow A in Fig. 31(a-1)). The directions of the arrows shown in Fig. 32(a-1) and (a-2) correspond to the directions of the arrows shown in Fig. 2.

[0177] The large electrolytic capacitor Cp2 is mounted in the region BP4. As shown in Fig. 29, two large electrolytic capacitors are mounted behind the large electrolytic capacitor (Cp2) mounted in the region BP4, and these large electrolytic capacitors are also the same size as the large electrolytic capacitor Cp2 shown in Figs. 32(a-1) and (a-2). As shown in Figs. 32(a-1) and (a-2), two lead wires LN1 and LN2 extend from the bottom surface of the large electrolytic capacitor Cp2, and the large electrolytic capacitor Cp2 is mounted on the board so that the lead wires LN1 and LN2 are aligned vertically (in other words, the line connecting the lead wires LN1 and LN2 is oriented vertically).

[0178] 32(b-1) and (b-2) show the mounting state of the components attached to the region BP5 of the power supply board 550 shown in FIG. 29. Here, FIG. 32(b-1) shows the state when the region BP5 is viewed from the front to the rear, and FIG. 32(b-2) shows the state when the region BP5 is viewed from the right to the left (the direction of the arrow A in FIG. 31(b-1)). The directions of the arrows shown in FIG. 32(b-1) and (b-2) correspond to the directions of the arrows shown in FIG. 2. The LEDLp3 is mounted in the region BP5, and as shown in FIG. 32(b-1) and (b-2), two lead wires LN3 and LN4 extend from the bottom surface of the LEDLp3. The LEDLp3 is mounted on the board so that the lead wires LN3 and LN4 are aligned vertically (in other words, the direction of the line connecting the lead wires LN3 and LN4 is vertical).

[0179] Figures 32(c-1) and (c-2) show the mounting state of the components attached to the area BS3 of the sub-main board 510 shown in Figure 28. Here, Figure 32(c-1) shows the state when the area BS3 is viewed from right to left, and Figure 32(c-2) shows the state when the area BS3 is viewed from rear to front (the direction of arrow A in Figure 31(c-1)). The directions of the arrows shown in Figures 32(c-1) and (c-2) correspond to the directions of the arrows shown in Figure 2.

[0180] A fuse Fs1 held by fuse clips Fh1 and Fh2 is mounted in region BS3. Terminals LN5a and LN5b arranged side by side in the left-right direction are protruding from the bottom of the fuse clip Fh1, and terminals LN6a and LN6b arranged side by side in the left-right direction are protruding from the bottom of the fuse clip Fh2. The terminals LN5a, LN5b, LN6a, and LN6b of the fuse clips Fh1 and Fh2 are soldered to the power supply board 550 in the vertical direction with a gap therebetween that is sufficient to hold the fuse Fs1.

[0181] In Figures 32(c-1) and (c-2), the fuse Fs1 is held by fuse clips Fh1 and Fh2, but a fuse having lead wires extending from both ends of the fuse body, such as fuse Fp1 shown in Figures 30(c-1) to (c-3), may also be mounted on a board so that the lead wires are lined up in the vertical direction (in other words, the line connecting the two lead wires is vertical).

[0182] Here, for example, if a large impact is applied in the vertical direction when the slot machine 1 is lowered to the ground during the transportation process of the slot machine 1, the main body of the component mounted on the board may tilt in the vertical direction due to the impact. In particular, since the size and weight of the main body of a large electrolytic capacitor are large, if the two lead wires are mounted on the board in a state where they are arranged horizontally, when a large impact is applied in the vertical direction, the lead wires are easily bent and the main body of the component may tilt in the vertical direction, and the lead wires may be subjected to a large load and break. Therefore, as shown in each diagram of FIG. 33, in this embodiment, the component is mounted on the board so that the multiple lead wires extending from the component are arranged in the vertical direction. Therefore, even if a large force in the vertical direction acts on the main body of the component due to a large impact in the vertical direction applied to the slot machine 1, the tilt of the main body of the component in the vertical direction is suppressed, so that it is possible to prevent malfunctions such as breakage of the lead wires of the component mounted on the board due to the applied impact. In this way, by making it difficult for malfunctions of the components to occur, the risk of the game machine stopping operation can be reduced, and the player can play smoothly. In addition, the lead wires of small and medium-sized electrolytic capacitors, which are less susceptible to the effects of shocks than large electrolytic capacitors, may be mounted on the board so that they are aligned in the left-right direction.

[0183] The direction of the lead wires of the components mounted on the board is not limited to the large electrolytic capacitor, LED, and fuse shown in FIG. 32, but can also be applied to other components. For example, the lead wires of the fuse Fp1 in the region BP2 shown in FIG. 30(c-1)-(c-1) and FIG. 31(b-1)-(b-3) may be mounted on the board so that they are aligned vertically. In this case, when the fuse Fp1 is tilted upward as described above, the lead wires of the fuse Fp1 do not come into contact with the lead wires of the ceramic capacitor Cp1, and when the fuse Fp1 is tilted downward, the main body does not protrude from the periphery of the board. In addition, it is possible to prevent the lead wires from breaking due to an impact applied to the slot machine 1.

[0184] As shown in Fig. 33(a-1) to (a-3), the directions of the lead wires of the components shown in Fig. 32 can also be applied to the toroidal coil TLp1 attached to the region BP6 of the power supply board 550 shown in Fig. 29. Here, Fig. 33(a-1) shows the state when the region BP6 is viewed from the front to the rear, Fig. 33(a-2) shows the state when the region BP6 is viewed from the right to the left, and Fig. 33(a-3) shows the state when the region BP6 is viewed from the bottom to the top. The directions of the arrows shown in Fig. 33(a-1) to (a-3) correspond to the directions of the arrows shown in Fig. 2.

[0185] In the toroidal coil TLp1, one end LN7 and the other end LN8 of the winding wound around the toroidal core tc, which is a ring-shaped body with a rectangular cross section, play the role of lead wires. When the toroidal coil TLp1 is viewed from the front to the rear as shown in FIG. 33(a-1), one end LN7 of the winding extends from the upper side of the toroidal core tc, and the other end LN8 extends from the lower side of the toroidal core tc. When the toroidal coil TLp1 is viewed from the right to the left as shown in FIG. 33(a-1), the one ends LN7 and LN8 of the winding extend from the center position of the toroidal core tc in the front-rear direction. Therefore, the toroidal coil TLp1 is mounted on a board so that the one ends LN7 and LN8 of the winding are aligned vertically (in other words, the direction of the line connecting the lead wires LN7 and LN8 is vertical).

[0186] In addition, in the power supply device 55 of this embodiment, the power supply board 550 is housed in a housing consisting of a resin front panel and a metal box, but it may be housed in a transparent resin board case such as the main board case 210 shown in Fig. 7. In this case, the power switch installed on the resin front panel may be mounted on the power supply board 550, and an opening for the power switch may be provided in the cover of the board case so that it can be turned on / off from outside. Even in such a configuration, the direction of the lead wires of the components mounted on the board shown in Fig. 32 can be applied.

[0187] As an example, Figures 33(b-1) and (b-2) show a state in which a power switch is mounted on a power supply board 550'. Figure 33(b-1) shows the state when the power supply board 550' is viewed in a direction from the front to the rear, and Figure 33(b-2) shows the state when the power supply board 550' is viewed in a direction from the right to the left. The directions of the arrows shown in Figures 33(b-1) and (b-2) correspond to the directions of the arrows shown in Figure 2.

[0188] The power switch SW1 shown in Figures 33(b-1) and (b-2) is provided with four terminals, namely, terminals LN9a, LN9b, and terminals LN10a and LN10b, which are spaced apart in the vertical direction. Also, as shown in Figure 33(b-2), the terminals LN9a, LN9b, and terminals LN10a, LN10b are provided on the power switch SW1 aligned in the front-rear direction, respectively. In this case, the power switch SW1 is mounted on the power supply board 550' so that the terminals LN9a, LN9b, and terminals LN10a, LN10b are positioned in the vertical direction.

[0189] The arrangement of components on the board shown in Figures 30 to 33 has been described using the components mounted on sub-control board 502 and power supply board 550 as examples, but it can also be applied to components mounted on main control board 111. The arrangement of components on the board shown in Figures 30 to 33 is not limited to boards provided in slot machines, but can also be applied to boards provided in pachinko gaming machines.

[0190] <Reel unit configuration> Next, the structure of the reel unit 60 shown in FIG. 3 will be described with reference to FIGS. 34 to 40. As shown in FIG. 34, the reel unit 60 is configured to include first to third reel modules 600a to 600c, a reel module mounting member 61, a relay board 65, and a board cover 66. The reel module mounting member 61 is made of a resin material and formed in a box shape with openings on the front and right sides, and is configured to be able to accommodate the first to third reel modules 600a to 600c lined up in the left-right direction (see the arrows in FIG. 2). That is, the reel module mounting member 61 has three storage positions, left, center, and right, and the first reel module 600a is accommodated in the left storage position, the second reel module 600b is accommodated in the center storage position, and the third reel module 600c is accommodated in the right storage position.

[0191] An upper flange portion 62 is formed above the opening of the reel module mounting member 61, and an upper bracket coupling portion 602 formed on the upper part of the reel bracket 601 in each of the first to third reel modules 600a to 600c is coupled to the upper flange portion 62 by a bracket coupling member 641. A lower flange portion 62 is formed below the opening of the reel module mounting member 61, and a lower bracket coupling portion 608 formed on the lower part of the reel bracket 601 in each of the first to third reel modules 600a to 600c is coupled to the lower flange portion 62 by a bracket coupling member 641.

[0192] A board mounting section 64 is formed on the upper part of the reel module mounting member 61. A relay board 65 and a board cover 66 are attached to the board mounting section 64. The relay board 65 is attached and fixed to the board mounting section 64 by a fixing means (not shown) such as a screw. The relay board 65 is electrically connected to the main control device 100, and controls the operation of the first to third reel modules 600a to 600c in response to a reel control signal transmitted from the main control device 100. The relay board 65 also relays various commands transmitted from the main control device 100 to the sub-control device 500, and relays signals exchanged between the main control device 100 and the medal payout device 50. The board cover 66 is formed in a box shape capable of covering the relay board 65 from above using a transparent resin material, and is coupled and attached to the board mounting section 64 by a cover coupling member (not shown).

[0193] (Reel module configuration) Next, the first to third reel modules 600a to 600c will be described with reference to Figures 35 and 36. The second reel module 600b has the same configuration as the first reel module 600a except that it uses a second reel 3b with a different pattern from the left reel 3a, and detailed illustrations and explanations will be omitted. The third reel module 600c has the same configuration as the first reel module 600a except that it includes a right reel 3c with a different pattern from the left reel 3a (and center reel 3b), and detailed illustrations and explanations will be omitted.

[0194] As shown in Figures 35 and 36, the first reel module 600a is configured to include a left reel 3a, a reel bracket 601, a reel sensor 621, a back lamp unit 650, a stepping motor 680, and a reel connecting member 690. The reel bracket 601 is formed into a plate shape using a resin material, and the stepping motor 680, the back lamp unit 650, and the reel sensor 621 (see Figure 36) are attached to the left side of the reel bracket 601. Here, the reel sensor 621 is a sensor that detects a detection piece (index) formed on a reel wheel 721 described later, and the position where the reel sensor 621 detects the index becomes the rotation reference position described above.

[0195] A plate-shaped upper bracket coupling portion 602 is formed on the upper front side of the reel bracket 601. The upper bracket coupling portion 602 is coupled to the left middle portion of the upper flange portion 502 (see FIG. 34) of the reel module mounting member 61 using a bracket coupling member 641. A plate-shaped lower bracket coupling portion 608 is formed on the lower front side of the reel bracket 601. The lower bracket coupling portion 608 is coupled to the left middle portion of the lower flange portion 508 (see FIG. 34) of the reel module mounting member 61 using the bracket coupling member 641. The bracket coupling member 641 is configured using a Nylatch or the like.

[0196] An upper connector mounting portion 603 is formed on the left side of the upper bracket joint portion 602. A first motor cable connector 606 (see FIG. 34) is attached to the upper connector mounting portion 603, to which a bifurcated motor cable (not shown) connected to the stepping motor 680 and the reel sensor 621 is connected. This first motor cable connector 606 is connected to the reel relay board 65 (see FIG. 34) by a cable. Guide pin engagement holes 604 are formed on both sides of the upper connector mounting portion 603, into which guide pins 607 (see FIG. 34) of the first motor cable connector 606 engage. The first motor cable connector 606 attached to the upper connector mounting portion 603 is adapted to be fitted and electrically connected to a reel relay connector (not shown) disposed at the front of the reel relay board 65 when the first reel module 600a is accommodated in the reel module mounting member 61.

[0197] One of the forks in the motor cable is electrically connected to the motor connector 675 of the stepping motor 680, and the other is electrically connected to a sensor connector (not shown) of the reel sensor 621. Also, a cable insertion portion 605 is cut out and formed in the lower right portion of the upper bracket joining portion 602, through which the motor cable extending toward the stepping motor 680 and the reel sensor 621 is inserted.

[0198] A rear connector mounting portion 613 is formed on the upper rear side of the reel bracket 601. A first lamp cable connector 616 is attached to the rear connector mounting portion 613. The first lamp cable connector 616 is provided at one end of a lamp cable (not shown) that is electrically connected to a back lamp board 653 (see FIG. 38) on which a plurality of high brightness LEDs are mounted. Guide pin engagement holes 614 are formed on both sides of the rear connector mounting portion 613, into which a guide pin 617 of the first lamp cable connector 616 engages. When the first reel module 600a is accommodated in the reel module mounting member 61, the first lamp cable connector 616 attached to the rear connector mounting portion 613 is fitted with a lamp relay connector (not shown) arranged on the lamp relay board, thereby being electrically connected to the back lamp board 653.

[0199] When the first reel module 600a is accommodated in the reel module mounting member 61, the first motor cable connector 606 (see FIG. 34) fits and is electrically connected to a reel relay connector (not shown) arranged on the reel relay board 65, and the first lamp cable connector 616 fits and is electrically connected to a lamp relay connector (not shown) arranged on the lamp relay board. Thus, simply by performing the work of accommodating and mounting the first reel module 600a in the reel module mounting member 61, the stepping motor 680 and the reel sensor 621 can be electrically connected to the reel relay board 65, and the back lamp board 653 can be electrically connected to the lamp relay board (not shown). Therefore, it is no longer necessary to use individually prepared cables to separately electrically connect the stepping motor 680 and the reel relay board 65, the reel sensor 621 and the reel relay board 65, and the back lamp board 653 and the lamp relay board (not shown), as was done in the conventional method, and the assembly work of the reel unit 200 can be performed efficiently.

[0200] The stepping motor 680 rotates the left reel 3a, and is attached and fixed to the motor attachment portion 631 of the reel bracket 601. A through hole provided at the rotation center of the left reel 3a is inserted into the output shaft of the stepping motor 680, and the left reel 3a is fixed to the output shaft of the stepping motor 680 by a reel connecting member 690.

[0201] (Back lamp unit configuration) Next, the configuration of the back lamp unit 650 will be described with reference to Fig. 37. Here, Fig. 37(a) is a perspective view of the back lamp unit 650, and Fig. 37(b) is a front view of the back lamp unit 650. The back lamp unit 650 is composed of a back lamp house 651 attached to the reel bracket 601, and a back lamp board 653 (see Fig. 38) attached to the back side of the back lamp house 651.

[0202] The back lamp board 653 is mounted with a plurality of LED elements for illuminating the three symbols displayed in the upper, middle, and lower rows of the reel window W from inside the reel. In this embodiment, six LED elements (total of 18) are mounted corresponding to each of the three symbols displayed in the reel window W. Specifically, six LED elements 654a for illuminating the symbols in the upper row of the reel window W, six LED elements 654b for illuminating the symbols in the middle row of the reel window W, and six LED elements 654c for illuminating the symbols in the lower row of the reel window W are mounted on one back lamp board 653. The six LED elements corresponding to the positions of the upper, middle, and lower rows are arranged in a matrix of two rows and three columns at a predetermined interval from each other.

[0203] The back lamp house 651 is made of a resin material, and a mounting arm portion 652 for mounting the back lamp house 651 to the reel bracket 601 is formed on the right side of the back lamp house 651. Also, three pattern lighting areas 661a, 661b, and 661c for illuminating the upper, middle, and lower patterns are formed on the back lamp house 651. Here, the pattern lighting area 661a is an area for illuminating the upper pattern, the pattern lighting area 661b is an area for illuminating the middle pattern, and the pattern lighting area 661c is an area for illuminating the lower pattern.

[0204] The symbol lighting area 661a is formed by an LED exposed surface 663a and a shade portion 664a. The LED exposed surface 663a is a rectangular surface facing the inner circumferential surface of the reel, and the LED exposed surface 663a is provided with openings 662a for exposing the light-emitting surfaces of the LED elements 654a, one for each of the six LED elements 654a (six in total). The shade portion 664a has a cylindrical shape extending from each of the upper, lower, left, and right peripheral portions of the LED exposed surface 663a toward the inner circumferential surface of the reel. The inner surface of the shade portion 664a is inclined so that the opening of the symbol lighting area 661a gradually widens from the LED exposed surface 663a toward the inner circumferential surface of the reel. The symbol lighting area 661b is also formed by an LED exposed surface 663b and a shade portion 664b similar to the LED exposed surface 663a and the shade portion 664a of the symbol lighting area 661a. The pattern lighting area 661c is also formed by an LED exposed surface 663c and a shade portion 664c similar to the LED exposed surface 663a and the shade portion 664a of the pattern lighting area 661a. Here, the color of the LED exposed surfaces 663a, 663b, 663c and the shade portions 664a, 664b, 664c is white, which allows more light from the six LED elements 654a to be reflected. For reference, the LED exposed surface 663a is shown by a diagonal line slanting upwards to the right in FIG. 37(b).

[0205] The symbol lighting area 661a and the symbol lighting area 661b are separated by a partition plate 665a having a thickness of TH3. The symbol lighting area 661b and the symbol lighting area 661c are separated by a partition plate 665b having a thickness of TH3. Here, the top plate portion 650a and the bottom plate portion 650b of the back lamp house 651 protrude forward (toward the reel 3a) more than the partition plates 665a and 665b. The thickness TH4 of the top plate portion 650a and the bottom plate portion 650b of the back lamp house 651 is thicker than the thickness TH3 of the partition plates 665a and 665b. Furthermore, the width of the symbol lighting area 661b in the rotation direction of the reel 3a is narrower than the widths of the symbol lighting areas 661a and 661c. By configuring the back lamp house 651 in this manner, the light from the LED elements 654 a , 654 b , and 654 c is less likely to leak from the back lamp house 651 .

[0206] The six openings formed in each of the LED exposed surfaces 663a, 663b, 663c are provided so as to match the mounting positions of the six LED elements 654a when the back lamp board 653 is attached to the back side of the back lamp unit 650. Furthermore, the upper, lower, left, and right surfaces forming each of the shade portions 664a, 664b, 664c are inclined so that the openings gradually widen from the corresponding LED exposed surfaces 663a, 663b, 663c toward the inner circumferential surface of the reel.

[0207] Although six openings 662a, 662b, 662c corresponding to six LED elements are provided on the LED exposed surfaces 663a, 663b, 663c of the back lamp house 651 shown in Fig. 37, the shape of the openings is not limited to this. Here, a modified example of the openings provided on the LED exposed surface will be described with reference to Fig. 38. In Fig. 38, the same components as those in Fig. 37 are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0208] The openings 662a', 662b', 662c' provided in the LED exposed surfaces 663a, 663b, 663c of the back lamp house 651' shown in Fig. 38 are not provided corresponding to each of the six LED elements, but are one opening that includes all of the light emitting surfaces of the six LED elements. Here, the color of the LED exposed surfaces 663a, 663b, 663c and the shade parts 664a, 664b, 664c of the back lamp house 651' shown in Fig. 38 is white like the back lamp house 651 in Fig. 37, but the surface of the back lamp board 653 exposed from the openings 662a', 662b', 662c' in the LED exposed surfaces 663a, 663b, 663c is also colored white.

[0209] In this way, by forming one large opening for six LED elements, it becomes easy to align the six LED elements with one opening when attaching the back lamp board 653 to the back side of the back lamp house 651, and the burden of assembling the back lamp unit 650 can be reduced. In addition, the height of the left and right side walls of the back lamp house 651 extends to the position of the front end of the partition plates 664a and 664b. This makes it possible to reduce the light leaking to the outside from the side walls of the back lamp house 651, and to illuminate the pattern more brightly.

[0210] (Reel structure) Next, the structure of the reels 3a to 3c will be described with reference to FIG. 39. Here, since the reels 3a to 3c have the same structure, the structure of the left reel 3a will be described below as an example. As shown in FIG. 39, the left reel 3a is configured to have a reel tape 711, a reel wheel 721, and a reel frame 731. The reel tape 711 is formed into a ring shape with a plurality of patterns (20 patterns in this embodiment) drawn on the outer circumferential surface by joining ends of a film material formed in a long and narrow strip shape with a reel width RW as shown in FIG. 39. The right peripheral edge of the reel tape 711 is wound around the outer circumferential surface portion 732 of the reel frame 731, and the left peripheral edge is wound around the outer circumferential surface portion 722 of the reel wheel 721. As a result, the reel tape 711 has a cylindrical shape with the wheel 721 and the reel frame 731 as the bottom surface and the reel tape 711 as the side surface.

[0211] As shown in Fig. 40, the reel tape 711 is divided into 20 equal lengths DL (indicated by dashed lines in Fig. 40) in the longitudinal direction (i.e., the circumferential direction of the reel 3a) into 20 symbol display areas, and one symbol is displayed in each symbol display area. In Fig. 40, seven symbols (from the top to the bottom in the figure, "watermelon", "bell", "replay", "cherry", "seven", "bar", "bell", and "replay") are shown as examples of the 20 symbols displayed on the left reel 3a.

[0212] The area of ​​each of the 20 symbol display areas is the same (=reel width RW×length of one section DL), but the size of the symbol displayed in each symbol display area varies depending on the type of symbol. Therefore, the intervals between the symbols displayed on the reel tape 711 are not uniform. In this embodiment, as shown in FIG. 40, the interval DGmin between the "Seven" symbol and the "Bar" symbol is the narrowest interval (hereinafter, the "interval DGmin" is referred to as the "minimum symbol interval DGmin"). Among these symbols, the "Seven" symbol has a transparent region LT that transmits light from the back lamp without diffusing it (i.e., you can see the other side through the reel tape 711). In the "Seven" symbol, the color of the colored areas other than the transparent region LT is red, and the transparent region LT is also colored red.

[0213] The length of the minimum symbol interval DGmin is longer than the movement distance Ad of the symbols when the stepping motor 680 shown in Fig. 36 rotates by one step. This makes it difficult for the illumination of the symbols by the back lamp to be adversely affected even if the stopping positions of the symbols vary when the reel 3a stops rotating.

[0214] Returning to Fig. 39, the reel wheel 721 is formed in a substantially disk-like shape using a resin material, and has an outer circumferential ring portion 722 formed in an annular shape, a hub portion 723 connected to the output shaft of the stepping motor 680, and four spoke portions 724 connecting the outer circumferential ring portion 722 and the hub portion 723. The outer circumferential ring portion 722 is formed with an outer circumferential surface portion 725 around which the left peripheral edge portion of the reel tape 711 is affixed and wound. A wheel rim portion 726 of width Wr is formed on the right end portion of the outer circumferential surface portion 725, which extends radially inward of the outer circumferential ring portion 224 (in other words, toward the center of rotation of the left reel 3a).

[0215] The reel frame 731 is formed in an annular shape using a resin material, as shown in Fig. 39. An outer peripheral surface portion 732 is formed on the outer periphery of the reel frame 731, around which the right peripheral edge of the reel tape 711 is affixed and wound. A frame rim portion 733 of width Wr is formed on the left end portion of the outer peripheral surface portion 732, which extends radially inward of the reel frame 731 (in other words, toward the center of rotation of the left reel 3a).

[0216] <Relationship between the back lamp house and the reel> Hereinafter, a characteristic relationship between the back lamp house 651 and the reels 3a, 3b, and 3c will be described. (Relationship between the back lamp house and the reel symbols) In this embodiment, the sizes of the LED exposed surfaces 663a, 663b, and 663c shown in Fig. 37 and Fig. 38 are smaller than the size of the symbol display area shown in Fig. 40. More specifically, the ranges of the LED exposed surfaces 663a, 663b, and 663c are sized to fit within the range of the symbol display area. More preferably, the ranges of the LED exposed surfaces 663a, 663b, and 663c are configured to fit within the outline of the largest symbol among the symbols displayed on the reel tape 711.

[0217] As described above, for example, the shade portion 664a is inclined so that the opening of the symbol illumination area 661a gradually widens from the LED exposed surface 663a toward the periphery of the reel contents (the same applies to the shade portions 664b and 664c). Here, if the shape of the LED exposed surface 663a becomes too large, the inclination of the shade portion 664a described above becomes gentler, and the light illuminating the symbols on the reels becomes more likely to be uneven. For this reason, by configuring the sizes of the LED exposed surfaces 663a, 663b, and 663c to have the above-mentioned relationship, the light illuminating the symbols on the reels becomes less uneven, and the symbols can be clearly illuminated. This improves the visibility of the symbols, allowing the player to play smoothly.

[0218] In this embodiment, the color of the area other than the pattern displayed on the reel tape 711 (hereinafter, also referred to as the "background color of the reel tape") is different from the color of the LED exposed surfaces 663a, 663b, 663c and the side surfaces of the shade parts 664a, 664b, 664c viewed through the transparent area LT shown in FIG. 40. In addition, the background color of the reel tape is different from the color of the end surfaces of the partition plates 665a, 665b and the shade parts 664a, 664b, 664c viewed through the transparent area LT (surfaces indicated by diagonal lines slanting downward to the right in FIG. 37(b)). Here, examples of "different colors" include a case where one is achromatic and the other is chromatic, or a case where the other color is a color other than a similar hue of the one color (more preferably, the other color is a color corresponding to the opposite hue of the one color). The background color of the reel tape, the color of the LED exposed surfaces 663a, 663b, 663c when viewed directly, and the color of the LED exposed surfaces 663a, 663b, 663c when viewed through the transparent region LT may be different from each other regardless of whether the LED elements 654a, 654b, 654c are lit or not. Furthermore, when the LED elements 654a, 654b, 654c are not lit, the positions of the LED elements 654a, 654b, 654 cannot be identified through the transparent region LT.

[0219] By configuring it in this way, it is possible to prevent the transparent area LT of the visible pattern from blending into the background color of the reel tape, which would reduce visibility. Also, even if the LED element mounted on the back lamp board 653 malfunctions and the pattern cannot be illuminated, the visibility of the light-transmitting area LT is unlikely to decrease, making it easier to press the buttons, allowing the player to play smoothly.

[0220] In this embodiment, the thickness TH3 of the partitions 665a, 665b shown in Figures 37 and 38 is smaller than the minimum symbol interval DGmin shown in Figure 40. With this configuration, the partitions 665a, 665b can prevent the lights of the lights for the symbols in the upper, middle, and lower rows of the reel window W from interfering with each other, and the lights for illuminating the symbols can be illuminated as a whole without being blocked by the partitions 665a, 665b, improving the visibility of the symbols and allowing the player to play smoothly.

[0221] (Relationship between the back lamp house and the reel structure) In this embodiment, as shown in Fig. 36, the reel 3a is fixed to the output shaft of the stepping motor 680 with the back lamp module 650 sandwiched between a wheel rim portion 726 formed on the reel wheel 721 and a frame rim portion 733 (see Fig. 39) formed on the reel frame 731. At this time, the wheel rim portion 726 and the frame rim portion 733 extend toward the rotation center side of the reel 3a beyond the position of the opening of the back lamp house 651. Therefore, the opening of the back lamp house 651 is surrounded by the wheel rim portion 726 of the reel wheel 721, the reel tape 711, and the frame rim portion 733 of the reel frame 731.

[0222] As a result, even if the reel connecting member 690 becomes detached, either the wheel rim portion 726 or the frame rim portion 733 will catch on the back lamp house 651, preventing the reel 3a from falling off the reel module 600a, thereby reducing the risk of damage to the reel 3a.

[0223] Furthermore, for example, if the wheel rim portion 726 and the frame rim portion 733 are made of a material that does not transmit light, or if they are made of a material that transmits light but are painted in a color that does not transmit light (for example, black), the light leaking from the side wall of the back lamp house 651 can be blocked by the wheel rim portion 726 and the frame rim portion 733. This allows more light to be irradiated onto the symbols, improving their visibility and allowing the player to play smoothly.

[0224] <Measures against fraud> Next, the relationship between the color of the material of the cabinet 5 and the paint color will be described with reference to Fig. 41. Fig. 41(a) is a right side view of the slot machine 1 installed in the gaming machine rack MC in the hall, and Fig. 41(b) is a cross-sectional view of the screw hole provided in the right side plate 5b. The directions of the arrows shown in Figs. 41(a) and (b) correspond to the directions of the arrows shown in Fig. 2.

[0225] In this embodiment, the material of the cabinet 5 shown in FIG. 2 and FIG. 6 is a light brown particle board, and the surfaces of the left side plate 5a, the right side plate 5b, and the top plate 5c constituting the cabinet 5 are painted black, while the surfaces of the bottom plate 5d and the back plate 5e are not painted. As shown in FIG. 3, the medal payout device 50 is installed on the bottom plate 5d inside the cabinet 5, and due to the size of the medal payout device 50, the length of the bottom plate 5d in the front-rear direction is longer than the length of the top plate 5c. Therefore, the shape of the left side plate 5a and the right side plate 5b is a substantially right-angled trapezoid with the back plate 5e at a right angle. When the cabinet 5 having such a shape is installed in the rack MC for game machines in the hall, a part of the right side plate 5b (and the left side plate 5a) (the part shown by the diagonal lines in FIG. 41(a)) has to be exposed to the outside in order to make the front door 2 openable and closable.

[0226] Here, for example, if someone commits fraud by drilling a hole in the exposed part of the right side panel 5b, the side of the drilled hole will be light brown, which is the color of the particle board material. Therefore, since a light brown area appears on the surface of the right side panel 5b against the black paint, it is easy to notice that the housing 5 has been damaged.

[0227] As shown in Fig. 41(a), the exposed portion of the right side plate 5b is provided with a screw hole SRH for attaching various devices and components inside the housing 5. As shown in Fig. 41(b), this screw hole SRH is a countersunk hole to prevent the head of the screw SCR from protruding from the surface of the housing, and the countersunk surface CHF is also painted black. As a result, if the countersunk surface CHF is damaged, for example, in an attempt to commit fraud, a light brown area appears on the black painted background, making it easy to notice that the countersunk surface CHF has been damaged.

[0228] Next, referring to FIG. 42, the signal paths exchanged between various devices installed inside the housing 5 will be described. FIG. 42 shows the signal paths exchanged between the main control device 100 and the stop switches 26a, 26b, and 26c, the medal payout device 50, and the external centralized terminal board 80. As shown in FIG. 42, the main control device 100 and the stop switches 26a, 26b, and 26 are electrically connected by a signal line sg1, and the main control device 100 and the reel relay board 65 are electrically connected by a signal line sg2 and a signal line sg3. In addition, the reel relay board 65 and the medal payout device 50 are electrically connected by a signal line sg4, and the reel relay board 65 and the external centralized terminal board 80 are electrically connected by a signal line sg5.

[0229] By such a signal path, for example, the stop operation signal outputted from the stop switches 26a, 26b, 26c to the main control device 100 is inputted directly to the main control device 100 via the signal line sg1. As a result, the main control device 100 performs the stop control of the reels 3a, 3b, 3c. Furthermore, if the main control device 100 performs the stop control for all the reels and a minor winning combination is achieved, it outputs a medal payout signal to the medal payout device 50 to pay out a predetermined number of medals. This medal payout signal is once outputted to the reel relay board 65 via the signal line sg2, and then outputted from the reel relay board 65 to the medal payout device 50 via the signal line sg4. As a result, the medal payout device 50 outputs a payout completion signal to the main control device 100 every time it pays out one medal.

[0230] This payout completion signal is once output to the reel relay board 65 via signal line sg4, and then output from the reel relay board 65 to the main control device 100 via signal line sg2. The main control device 100 then counts the number of times the payout completion signal has been input, and when the number of medals corresponding to the winning minor role has been paid out, it stops outputting the medal payout signal. When the main control device 100 outputs a game information signal indicating the number of inserted medals and the number of paid out medals to the external centralized terminal board 80, the signal is first once transmitted to the reel relay board 65 via signal line sg3, and then transmitted from the reel relay board 65 to the external centralized terminal board 80 via signal line sg5. The external centralized terminal board 80 then outputs the input game information signal to an external hall computer or the like.

[0231] Here, for example, when the stop switches 26a, 26b, and 26c transmit a stop operation signal to the main control device 100 via the reel relay board 65, there is a risk of a fraudulent act being performed in which an illegal board having the following functions is attached to the reel relay board 65. First, when a stop operation signal is output from the stop switches 26a, 26b, and 26c to the reel relay board 65, the illegal board uses the stop operation signal as a trigger to prevent a payout completion signal from being output to the main control device 100 for a predetermined time, even if the payout completion signal is output from the medal payout device 50. Also, during this time, even if a game information signal is output from the main control device 100, the game information signal is not output to the external centralized terminal board 80.

[0232] As a result, when a medal payout signal is output from the main control device 100 to the medal payout device 50 via the reel relay board 65 during the above-mentioned predetermined time, the medal payout device 50 starts paying out medals in response to this, but the illegal board prevents the output of a payout completion signal to the main control device 100 until the above-mentioned predetermined time has elapsed. As a result, the main control device 100 cannot count the number of medals paid out, so the main control device 100 continues to output a medal payout signal, resulting in unfair medal payout. Also, during this time, a game information signal is not output to the external centralized terminal board 80, so the hall computer cannot recognize that an unnatural payout is being performed.

[0233] Therefore, in this embodiment, the signal path shown in Figure 42 is adopted, and the stop operation signal that triggers the above-mentioned fraudulent behavior is output directly to the main control device 100 without going through the reel relay board 65, thereby making it possible to nullify the above-mentioned fraudulent behavior.

[0234] <Information display lamp (role ratio monitor) display content> Next, the display contents of the information display lamp 156 shown in FIG. 13 will be described in detail with reference to FIG. 43. As shown in FIG. 43(a), the information display lamp 156 is composed of 4-digit 7-segment LEDs, the 7-segment LEDs of the upper two digits are the identification segment 156a, and the 7-segment LEDs of the lower two digits are the ratio segment 156b. The identification segment 156a displays information (hereinafter also referred to as "identifier") indicating the type of numerical value (ratio) displayed in the ratio segment 156b, and the ratio segment 156b displays a numerical value (ratio) corresponding to the identifier displayed in the identification segment 156a. There are six types of ratios displayed on the information display lamp 156: (1) instructed role ratio or advantageous zone ratio, (2) consecutive role ratio (6000 games), (3) role ratio (6000 games), (4) consecutive role ratio (cumulative), (5) role ratio (cumulative), and (6) role etc. state ratio. These ratios are displayed on the information display lamp 156 in a sequential and cyclical manner together with an identifier consisting of one digit and one alphabetic character.

[0235] Next, the above-mentioned six types of ratios will be explained with reference to FIG. 43(b). (1) Regarding the ratio of the device with instruction or the ratio of the advantageous zone, the ratio of the advantageous zone is a numerical value expressed as a two-digit percentage of the ratio of the number of games played in the advantageous zone (a game state in which the order of pressing the stop switch can be notified) out of the total number of games played (actually 175,000 games), and the identifier is "7U". The ratio of the device with instruction is a numerical value expressed as a two-digit percentage of the ratio of the number of medals paid out during the operation of the game and the device (first type special device (RB), second type special device (CB), and normal device (CB)) in which the order of pressing the stop switch is notified to the player out of the total number of medals paid out in the total number of games played (actually 175,000 games), and the identifier is "7P". Either the ratio of the device with instruction or the ratio of the advantageous zone is displayed depending on the specifications of the slot machine.

[0236] (2) The consecutive win ratio (6000 games) is, in principle, a double-digit percentage of the number of medals paid out during the operation of the first-class special feature among the number of medals paid out during the most recent 6000 games, and its identifier is "6y." (3) The winning ratio (6000 games) is, in principle, a double-digit percentage of the number of medals paid out during the operation of the first-class special feature, the second-class special feature, and the normal feature among the number of medals paid out during the most recent 6000 games, and its identifier is "7y."

[0237] (4) The consecutive role ratio (cumulative) is, in principle, a number that expresses the ratio of the number of medals paid out during the operation of the first type special role among the number of medals paid out during the most recent 17,500 games as a double-digit percentage, and has the identifier "6A". (5) The role ratio (cumulative) is, in principle, a number that expresses the ratio of the number of medals paid out during the operation of the first type special role, the second type special role, and the normal role among the number of medals paid out during the most recent 17,500 games as a double-digit percentage, and has the identifier "7A". (6) The role etc. status ratio is a number that expresses the ratio of the total number of times that the role (first type special role, second type special role, normal role, role continuous operation device) was operated among 175,000 games (cumulative number of games) as a double-digit percentage, and has the identifier "5H".

[0238] The information display lamp 156 displays the above-mentioned various information in the following order in a circular manner: (1) Indicated role ratio (or advantageous zone ratio) → (2) Consecutive role ratio (6000 games) → (3) Role ratio (6000 games) → (4) Consecutive role ratio (cumulative) → (5) Role ratio (cumulative) → (6) Role status ratio, etc. Each piece of information is displayed for 5 seconds (tolerance ±10%). Also, when the above-mentioned information is displayed on the information display lamp 156, the segment DP (see FIG. 43(a)) representing the decimal point is lit up in the 7-segment LED on the lower digit side of the identification segment 156a. As a result, the identification segment 156a will transition as follows: "7P." (or "7U.") → "6y." → "7y." → "6A." → "7A." → "5H." → "7P." (or "7U.") → ..., and the ratio segment 156b will display the percentage value corresponding to the displayed identifier.

[0239] In the ratio segment 156b, the percentage value corresponding to each of the above-mentioned display items (1) to (6) is displayed within the range of "00" to "99". The percentage value displayed in the ratio segment 156b is a value with the decimal point discarded, and when the calculated ratio is 100%, "99" is displayed in the ratio segment 156b. In addition, as shown in FIG. 43(b), a ratio threshold is set for each display item, and each ratio threshold is 70% for (1) the instructed role ratio or advantageous zone ratio, (3) role ratio (6000 games) and (5) role ratio (cumulative), 60% for (2) consecutive role ratio (6000 games) and (4) consecutive role ratio (cumulative), and 50% for (6) role etc. state ratio. When each display item is displayed, if the ratio of the display item is equal to or greater than the corresponding ratio threshold, the number displayed in the ratio segment 156b is displayed in a blinking manner.

[0240] In addition, for each of the display items (1) to (6), if the total number of games is less than the corresponding reference number of games because, for example, the slot machine has only recently started operating, the identifier displayed in the identification segment 156a is flashed. The reference number of games for each display item is, as shown in FIG. 43(b), 175,000 games for (1) instructed role ratio or advantageous zone ratio and (6) role etc. state ratio, 6,000 games for (2) consecutive role ratio (6,000 games) and (3) role ratio (6,000 games), and 17,500 games for (4) consecutive role ratio (cumulative) and (5) role ratio (cumulative). In addition, when the identification segment 156a and the ratio segment 156b flash, the total time of the on period and off period is 0.6 seconds (tolerance ±10%) and the duty ratio of the on period is 50%, resulting in a on period of approximately 0.3 seconds and an off period of approximately 0.3 seconds.

[0241] <Monitor LED list sticker> Next, the monitor LED list sticker LST shown in FIG. 6 will be described with reference to FIG. 44. FIG. 44(a) is an enlarged view of the periphery of 141 (more specifically, the area MON in FIG. 45(a) to be referred to later) of the main control board 110 shown in FIG. 13. Also, FIG. 44(b) is a view showing the contents of the monitor LED list written on the monitor LED list sticker LST. As described above, the main control board 110 is mounted with a monitor lamp 141 consisting of 20 LED elements 142 (only some of the LED elements are given reference numbers to avoid cluttering the illustration), and the part numbers (D1 to D20) given to each LED element 142 are silk-printed on the part mounting surface of the main control board 110 as shown in FIG. 44(a).

[0242] Specifically, of the 20 LED elements 142 arranged in two rows, one above the other, the 10 LED elements 142 in the lower row are indicated by the silk screen print SLK1 with part numbers D1 to D10, starting from the left. The 10 LED elements 142 in the upper row are indicated by the silk screen print SLK2, which collectively lists the part numbers D11 to D20 of the LED elements 142, because there is no space on the component mounting surface to silk screen each LED element 142. This silk screen print SLK2 indicates that the 10 LED elements 142 in the upper row are assigned part numbers D11 to D20, starting from the left.

[0243] Next, the contents of the monitor LED list written on the monitor LED list sticker LST will be described with reference to FIG. 44(b). The monitor LED list is a table that lists the part numbers of the above-mentioned LED elements 142 and the names of the switches and sensors corresponding to each part number. For example, in the monitor LED list shown in FIG. 44(b), "start lever" is written for part number "D4", which indicates that the LED element 142 with part number "D4" (the fourth LED element 142 from the left in the lower row in FIG. 44(a)) corresponds to the start lever 25. Therefore, the LED element 142 with part number "D4" turns on or off depending on the operation of the start lever 25.

[0244] In this way, by attaching the monitor LED list sticker LST to the inside of the housing 5 (specifically, the left side plate 5a), when checking whether various switches and sensors of the slot machine are operating normally, it is possible to save the trouble of memorizing the correspondence between the 20 LED elements 142 and each switch or sensor, or preparing a service manual that describes the correspondence between the LED elements 142 and each switch or sensor. In addition, it is difficult to make a mistake in the correspondence between the LED elements 142 and each switch or sensor, and an accurate check can be performed. In addition, since the monitor LED list is represented by attaching a sticker rather than being engraved inside the housing 5, the housing of the slot machine can be recycled by peeling off the monitor LED list sticker, and there is also an advantage that, for example, even if the correspondence between the LED elements 142 and each switch or sensor is changed, the monitor LED list sticker can be easily updated.

[0245] In contrast, for the display contents of the information display lamp 156 described above (the ratio of the reels including instructions (or the ratio of the advantageous zone), the ratio of consecutive reels (6000 games), the ratio of the reels (6000 games), the ratio of consecutive reels (cumulative), the ratio of the reels (cumulative) and the ratio of the state of the reels, etc.), no list equivalent to the monitor LED list sticker LST is attached to the inside of the cabinet 5. This is because the number of items displayed on the information display lamp 156 is as small as six, and it is considered that the display contents of the information display lamp 156 can be easily understood without the trouble of clearly indicating the list. In addition, the display contents of the information display lamp 156 can be said to be a kind of game history information that indicates the ratio of the advantageous state for the player and the ratio of the profit given to the player in the advantageous state, and therefore it can be said to be information of a nature that should be kept secret from persons other than the related parties (for example, the player, etc.). Therefore, if the display content of the information display lamp 156 is clearly written on the inside of the cabinet 5, for example, when the front door 2 is opened in a place where a player is present to deal with a problem such as a medal jam while the slot machine is in operation or to replenish medals, there is a risk that the display content of the information display lamp 156 may be known by the player, etc., so this can be avoided.

[0246] The part numbers (D1 to D20) given to each LED element 142 and the display contents (identifier and ratio) displayed on the information display lamp 156 are different information. Specifically, the information display lamp 156 is designed not to display a character string consisting of the alphabet "D" and the numbers "1" to "20." This is because if the same information were displayed, there is a risk that the contents of the identifier displayed on the information display lamp 156 would be mistakenly identified according to the description on the monitor LED list sticker LST. By making the information different in this way, the contents displayed on the information display lamp 156 will not be misinterpreted.

[0247] In order to avoid similar misidentification, it is preferable not to use the character strings used for the part numbers of each LED element 142 ("D1" to "D20", which are character strings consisting of the alphabet "D" and the numbers "1" to "20") as character strings to be written on crimping usage record labels, as identifier character strings displayed in the identification segment 156a, or as character strings indicating error codes. Similarly, it is preferable not to use the identifier character strings displayed in the identification segment 156a as character strings to be written on crimping usage record labels, as character strings indicating part numbers of electronic components or the like represented by silk screen printing on a board, or as character strings indicating error codes.

[0248] <Areas where electronic components cannot be mounted> Next, the mounting areas of electronic components on various boards of this embodiment will be described with reference to Fig. 45. Fig. 45 shows the component mounting surface (front surface FS) of main control board 110 as viewed from the front, with Fig. 45(a) showing the entire main control board 110 and Fig. 45(b) showing an enlarged view of area A (around upper right through hole th2) surrounded by a dashed line in main control board 110 shown in Fig. 45(a).

[0249] As shown in FIG. 45(a), four through holes th are provided at the four corners of the main control board 110 for fixing the main control board 110 to the case body 211 with mounting screws (not shown). Here, when the four through holes are to be distinguished from one another, they are called the upper left through hole th1, the upper right through hole th2, the lower left through hole th3, and the lower right through hole th4. In this embodiment, as shown in FIG. 45(b), a circular area of ​​radius r from the center thc of the upper right through hole th2 is an area where electronic components are not mounted (unmountable area). Here, the length of the radius r is the length of the mounting screw. Similarly, the circular areas of radius r from the center thc of the through holes around the upper left through hole th1, the lower left through hole th3, and the lower right through hole th4 are unmountable areas.

[0250] In this way, by designating a circular area of ​​radius r (the length of the mounting screw) from the center thc of the through hole as the non-mountable area, even if the mounting screw is bent, for example because the mounting screw is not screwed in completely and the head of the screw is raised above the board mounting surface when the case lid 221 is attached to the case body 211, it is possible to prevent the bent mounting screw from shorting out electronic components on the main control board 110 to ground or shorting out the lead wires of adjacent electronic components mounted together.

[0251] In the above example, main control board 110 is screwed to case body 211, but the above-mentioned non-mountable area may also be applied when main control board 110 is screwed to case lid 221. Here, with reference to Fig. 46, a structure that allows main control board 110 to be screwed to case body 211 and a structure that allows main control board 110 to be screwed to case lid 221 will be described. Fig. 46 is a view of main board case 210 shown in Fig. 45 viewed from the right side indicated by the arrow in Fig. 45(a) to the left side, and shows cross sections of case body 211 and case lid 221.

[0252] Also, Fig. 46(a) shows a structure that allows the main control board 110 to be screwed to the case body 211, and Fig. 46(b) shows a structure that allows the main control board 110 to be screwed to the case lid 221. In Figs. 46(a) and (b), the same reference numerals are used for common parts. Figs. 46(a) and (b) show a state in which the bottom plate Bp (also the case body 211) of the board case 210 is installed facing the inner surface of the back plate 5e of the housing 5, so the up-down, front-rear directions are the directions of the arrows in Fig. 46. Therefore, the top plate Tp of the board case 210 is the front side, and the bottom plate Bp is the rear side.

[0253] 46(a), four bosses BSL are formed on the inner surface of the case body 211 in accordance with the positions of four through holes th provided in the main control board 110. These bosses BSL have a cylindrical shape, and pilot holes for screwing in mounting screws scr are formed in the front end faces. Therefore, when storing the main control board 110 in the board case 210, the pilot holes formed in the four bosses BSL are aligned with the positions of the four through holes th of the main control board 110, and the main control board 110 is fastened with the mounting screws scr from the component mounting surface side of the main control board 110.

[0254] In contrast, in the structure of the board case 210 shown in Fig. 46(b), four bosses BSc are formed on the inner surface of the case lid 221 in accordance with the positions of the four through holes th of the main control board 110. As a result, when storing the main control board 110 in the board case 210, the positions of the four through holes th of the main control board 110 are aligned with the pilot holes formed in the four bosses BSc, and the main control board 110 is screwed in from the solder surface side with the mounting screws scr. Here, even when screwing in from the solder surface side of the main control board 110 with the mounting screws scr, it is desirable to provide the non-mounting area shown in Fig. 45(b). As a result, even if, for example, the mounting screw is not screwed in completely and the case lid 221 is attached to the case body 211 with the head of the screw floating above the board mounting surface, causing the mounting screw to bend when the case lid 221 is attached to the case body 211, it is possible to prevent the bent mounting screw from shorting out the lands formed on the solder surface of the main control board 110 or the lead wires of electronic components protruding from the solder surface, or shorting out the lead wires of electronic components mounted next to each other.

[0255] The distance between the control chip 121, setting display lamp 151, and information display lamp 156 mounted on the main control board 110 and the case lid 221 is wider than the overall length of the mounting screws for screwing the main control board 110 to the case body 211 and the longitudinal length of the main bodies of the various lead components mounted on the main control board 110. In this case, the lead components and mounting screws that have fallen off from the main control board 110 for some reason will not get caught between the control chip 121, setting display lamp 151, and information display lamp 156 and the case lid 221. Here, in the following description, "falling off" refers to the main body of the lead component being removed from the board due to, for example, the breakage of the lead wire of the lead component.

[0256] On the other hand, if the distance between the control chip 121, setting indicator lamp 151, and information indicator lamp 156 and the case lid 221 is narrower than the overall length of the mounting screws and the longitudinal length of the main body of the various lead parts, it is possible to eliminate any room for lead parts or mounting screws that have fallen off from the main control board 110 for some reason to get between the control chip 121, setting indicator lamp 151, and information indicator lamp 156 and the case lid 221.

[0257] In the above description, main control board 110 has been taken as an example, but similar unmountable areas may also be provided for sub-control board 502, power supply board 550, and various other relay boards. In addition, the length of radius r of the unmountable area is set to the length of the mounting screw, but it may be longer than the length of the mounting screw.

[0258] <Relationship between the size of the heat dissipation hole and the size of the electronic components and mounting screws> Next, with reference to Fig. 47 and Fig. 48, the relationship between the size of the heat sink provided in the board case and the size of the electronic components and mounting screws on the board housed in the board case will be described. Here, in the following description, the sub-board case 501 and the sub-control board 502 of the sub-controller 500 will be described as an example. Fig. 47(a)-(c) illustrates the sub-board case 501 in a state in which the sub-board case 501 of the sub-controller 500 is attached to the rear side of the front door 2. Fig. 47(a) is a schematic diagram showing the appearance of the sub-controller 500 and the sub-board case 501 when a part of the lower left side is viewed from diagonally downward to the left. Fig. 47(b) is a partial cross-sectional view of the sub-board case 501 when viewed from above. In this figure, various components mounted on the sub-control board 502 are omitted. Fig. 47(c) is a partial front view of the sub-board case 501. 48(a) to (d) are perspective views showing schematic external views of various parts attached to the sub-control board 502. FIG.

[0259] FIG. 47(a) shows a part of the left side plate SpL, the lower side plate SpD, and the top plate Tp of the sub-board case 501. A plurality of heat dissipation holes wh are provided at the corner where the lower side plate SpD and the top plate Tp are in contact. The heat dissipation hole wh is a hole for discharging the heat generated in the sub-board case 501, and is a continuous long hole extending from the lower side plate SpD to the top plate Tp. Here, the size of the heat dissipation hole wh will be described with reference to FIGS. 47(b) and (c). As shown in FIG. 47(b), the size of the heat dissipation hole wh in the lower side plate SpD is a rectangular long hole with a width W and a length L (W < L). In this figure, the top plate Tp of the sub-board case 501 is shown in cross section. Further, as shown in FIG. 47(c), the size of the heat dissipation hole wh in the top plate Tp is a rectangular long hole with a width W and a height H (W < H), and the height H of the heat dissipation hole wh is larger than the length L of the heat dissipation hole wh in the lower side plate SpD.

[0260] Next, with reference to FIG. 48, the size of the above-described heat dissipation hole wh, various lead components (electronic components having lead wires extending from the component body as terminals) mounted on the sub-control board, and the mounting screws will be described. FIGS. 48(a) to (c) show the shapes of the main types of lead components among the various electronic components mounted on the sub-control board 502. FIG. 48(a) shows the appearance of an axial lead component (a lead component having lead wires extending from both ends of the body) having a cylindrical body like a resistor, for example. Dimensions representing the size of such an axial lead component having a cylindrical body are the diameter d1 and the length L1. In the present embodiment, the length L1 > the diameter d1.

[0261] FIG. 48(b) shows the appearance of a radial type lead component (a lead component with a lead wire coming out from one end of the body) having a cylindrical body, such as an electrolytic capacitor. Dimensions that represent the size of such a radial type lead component having a cylindrical body include diameter d2 and height h2. In this embodiment, height h2>diameter d2. FIG. 48(c) shows the appearance of a radial type lead component having a rectangular parallelepiped body (strictly speaking, the corners and edges of the rectangular parallelepiped are rounded), such as a ceramic capacitor. Dimensions that represent the size of such a radial type lead component having a rectangular parallelepiped body include length L3, height h3, and thickness t3. In this embodiment, length L3>height h3>thickness t3.

[0262] 48(d) shows the appearance of the mounting screw for screwing the sub-control board 502 to the board case 501, and the dimensions that represent the size of this mounting screw include the diameter dk4 of the screw head, the total length of the screw (height of the screw head + length of the screw part) L4, and the nominal screw diameter da4. In this embodiment, the total length of the screw L4 > diameter dk4 of the screw head > nominal screw diameter da4.

[0263] Here, it is desirable that the minimum dimension (width W in this embodiment) of the shape of the heat dissipation hole wh is smaller than the minimum dimensions (diameter d1, diameter d2, thickness t3) of the various lead components described above. For example, various lead components and mounting screws mounted on the sub-control board 502 may fall off the sub-control board 502 due to a combination of factors such as poor soldering of the lead components and impacts during transportation of the slot machine 1 and opening and closing of the front door 2. For such a case, by setting the width W of the heat dissipation hole wh smaller than the maximum dimensions of the various lead components and mounting screws, it is possible to prevent the lead components that have fallen off the sub-control board 502 from falling outside the sub-board case 501 and adversely affecting other devices (for example, the hopper 51 and the power supply device 55) installed inside the housing 5. Note that in order to prevent the mounting screws that have fallen off the sub-control board 502 from falling outside the sub-board case 501, the minimum dimension of the shape of the heat dissipation hole wh may be made smaller than the diameter dk4 of the screw head of the mounting screw.

[0264] However, normally, it is unlikely that the lead components or mounting screws that have fallen off the sub-control board 502 will remain on the lower plate SpD of the board case 501 in an upright state. Here, "upright" refers to a posture in which the direction of the length L1 coincides with the vertical direction in the case of an axial lead component having a cylindrical body as shown in FIG. 48(a). Also, in the case of a radial lead component having a cylindrical body as shown in FIG. 48(b), it refers to a posture in which the direction of the height h2 coincides with the vertical direction. Also, in the case of a radial lead component having a rectangular parallelepiped body as shown in FIG. 48(c), it refers to a posture in which the direction of the length L3 or height h3 coincides with the vertical direction. Furthermore, in the case of a mounting screw as shown in FIG. 48(d), it refers to a posture in which the direction of the entire length L4 of the screw coincides with the vertical direction.

[0265] Therefore, the minimum dimension of the shape of the heat dissipation hole wh (width W in this embodiment) may be set to a size that prevents lead parts and mounting screws that have fallen off the sub-control board 502 from falling out of the heat dissipation hole wh to the outside when they are in a position to remain stably on the lower plate SpD of the board case 501.

[0266] Here, the "position where the component can be stably held" refers to a position where the side of the component body contacts the lower plate SpD in the case of an axial lead component having a cylindrical body as shown in FIG. 48(a). Also, in the case of a radial lead component having a cylindrical body as shown in FIG. 48(b), it refers to a position where the side of the component body contacts the lower plate SpD. Also, in the case of a radial lead component having a rectangular parallelepiped body as shown in FIG. 48(c), it refers to a position where the surface with the largest area among the surfaces of the component body contacts the lower plate SpD. Furthermore, in the case of the mounting screw as shown in FIG. 48(d), it refers to a position where the mounting screw contacts the lower plate SpD in a horizontal position.

[0267] The heat dissipation hole wh described above is a continuous long hole extending from the lower plate SpD to the top plate Tp of the sub-substrate case 501, but is not limited to this. A heat dissipation hole may be provided on only one of the lower plate SpD, top plate Tp, left side plate SpL, upper plate, and right side plate of the sub-substrate case 501, or a long hole extending to two adjacent adjacent surfaces may be provided, or the holes may be provided on all surfaces. The shape of the heat dissipation hole is not limited to a rectangle, but may be a circular hole or an oval hole. Regardless of how the heat dissipation holes are provided in the substrate case 501, by determining the dimensions of each heat dissipation hole as described above, it is possible to prevent lead components and mounting screws that have fallen off the sub-control substrate 502 from falling outside the sub-substrate case 501.

[0268] Furthermore, the lead components include LED elements, diodes, resistors, and various capacitors including ceramic capacitors and electrolytic capacitors, and any one or more types of these lead components may be considered as "predetermined lead components," and the dimensions of the heat dissipation holes may be determined as described above taking into consideration the shape and dimensions of the predetermined lead components to prevent them from falling out of the sub-board case 501. In particular, electrolytic capacitors tend to become larger and heavier depending on the rated voltage and capacity, increasing the risk of them falling out of the board, so it is preferable to determine the dimensions of the heat dissipation holes taking into consideration the dimensions and weight of such large electrolytic capacitors.

[0269] <Gap between the board and the board case> Next, the relationship between the distance between the board and the board case, and the size of the electronic components on the board and the mounting screws will be described with reference to Fig. 47(c) and Fig. 49. Here, Fig. 49(a) is a schematic diagram of a partial cross section of the sub-board case 501 when viewed from the side in a state in which the board case 501 of the sub-control device 500 is attached to the rear side of the front door 2. In this figure, the bottom plate Btp (also the main body of the sub-board case 502) of the sub-board case 502 faces the rear side of the front door 2, and the top plate Tp (also a part of the lid of the sub-board case 502) of the sub-board case 502 is in a position facing the inside of the housing 5. In addition, the component mounting surface of the sub-control board 502 housed in the sub-board case 502 is screwed to a boss (not shown) formed on the bottom plate Btp of the sub-board case 502 with the mounting screw (not shown) facing the inside of the housing 5. 49(b) and (c) are diagrams each showing a schematic diagram of the positional relationship between the sub-substrate case 501 and the sub-control substrate 502 when the top plate Tp of the sub-substrate case 502 is viewed from the front with the sub-substrate case 501 of the sub-control device 500 attached to the rear side of the front door 2. In addition, in Figs. 49(a) to (c), the same reference numerals are used for the same components as those shown in Figs. 47(a) to (c), and detailed explanations will be omitted.

[0270] As mentioned above, in order to prevent the various lead components and mounting screws mounted on the sub-control board 502 in the sub-board case 501 from adversely affecting the various components mounted on the sub-board case 501 when the various lead components and mounting screws fall off from the sub-control board 502, in this embodiment, the size of the distance dg from the lower end edg of the sub-control board 502 shown in Figure 47(c) to the inner surface Ms of the lower plate SpD is defined as follows.

[0271] The size of the above-mentioned interval dg is preferably equal to or larger than the maximum dimensions (length L1, height h2, length L3) of the various lead components shown in Figs. 48(a) to (c). In this way, by setting the size of the interval dg to be equal to or larger than the maximum dimensions of the various lead components, the lead components that have fallen off the sub-control board 502 will not come into contact with the sub-control board 502 after dropping onto the lower plate SpD. This makes it possible to prevent the leads of the lead components that have dropped onto the lower plate SpD from shorting out the electronic components on the sub-control board 502 to ground, or to prevent the leads of adjacent electronic components from shorting out. In addition, as shown in Fig. 49(a), a space K for holding the fallen lead components is formed below the sub-board case 501, so that the lead components that have fallen off the sub-control board 502 can be safely held within the space K. In order to prevent the mounting screw that has fallen off from the sub-control board 502 from coming into contact with the sub-control board 502 after it falls onto the lower plate SpD and to form space K for safely accommodating the dropped mounting screw, the size of the gap dg should be set to be equal to or greater than the overall length L4 of the mounting screw. By determining the size of the gap dg in this manner, the same advantages as in the case of the lead components described above can be obtained.

[0272] However, as mentioned above, it is usually unlikely that lead parts or mounting screws that have fallen off the sub-control board 502 will remain upright on the lower plate SpD of the board case 501, so the length of the gap dg may be set to a length that prevents the lead parts or mounting screws that have fallen off the sub-control board 502 from coming into contact with the lower end edg of the sub-control board 502 when they are in a position in which they remain stably on the lower plate SpD of the board case 501.

[0273] The shape of the space K capable of accommodating lead components and mounting screws that have fallen off from the sub-control board 502 varies depending on the shape of the sub-board case 501. For example, as shown in FIG. 49(b), a single space K extending across the entire width of the sub-board case 501 may be formed below the sub-board case 501, or, as shown in FIG. 49(b), multiple (two in FIG. 49(b)) divided spaces K1, K2 may be formed below the sub-board case 501 across the entire width of the sub-board case 501.

[0274] (Modification) Next, a modified example of the above-mentioned interval dg will be described with reference to FIG. 50. Here, FIG. 50(a) and (b) are diagrams each showing a schematic positional relationship between the sub-substrate case 501 and the sub-control substrate 502 when the sub-substrate case 501 of the sub-control device 500 is attached to the rear side of the front door 2 and the top plate Tp of the sub-substrate case 502 is viewed from the front. In this figure, the same components as those in FIG. 47 and FIG. 49 are given the same reference numerals, and detailed description thereof will be omitted. Also, FIG. 50(a) and (b) show the lowest component PML attached to the lowest side on the sub-control substrate 502. This lowest component PML is not limited to electronic components such as lead components and chip components, but may be components such as connectors, switches, and fuses.

[0275] In the above explanation, the distance dg from the inner surface Ms of the lower plate SpD to the lower end edg of the sub-control board 502 as shown in Fig. 50(a) was explained, but in this modified example, the length of the distance dpml from the inner surface Ms of the lower plate SpD to the lowermost component PML shown in Fig. 50(b) is set to be the same as the distance dg described above. By setting the distance dpml to be the same as the distance dg in this manner, it is not possible to form the space K described above below the sub-control board 502, but it is possible to prevent the leads of the lead components or mounting screws that have fallen onto the lower plate SpD from shorting out the electronic components on the sub-control board 502 to ground, or to prevent the leads of adjacent electronic components from being shorted out.

[0276] <Differences in characteristics depending on the mounting angle of the board case> Differences in characteristics according to the angle at which the sub-board case 501 described with reference to Figs. 47 to 50 is attached to the rear side of the front door 2 will be described with reference to Figs. 51 and 52. Figs. 51 and 52 show side views of the slot machine 1 as viewed from the right side, with Fig. 51 showing a state in which the sub-board case 501 is inclined forward (towards the front door 2) and attached to the rear side of the front door 2, and Fig. 52 showing a state in which the sub-board case 501 is inclined backward (towards the inside of the housing 5) and attached to the rear side of the front door 2. In these figures, the same reference numerals are used for the same configurations as those shown in Figs. 47 to 50, and detailed descriptions thereof will be omitted.

[0277] First, referring to Figures 51(a) and (b), the characteristics of the case where the sub-board case 501 is attached to the rear side of the front door 2 in a forward tilted position will be described. Here, Figure 51(a) is a side view of the slot machine 1 as viewed from the right side, in which the position (attaching position) in which the sub-board case 501 is attached to the rear side of the front door 2 is shown by a broken line. Also, Figure 51(b) is a schematic diagram of a partial cross section of the sub-board case 501 as viewed from the right side in the attachment position of the sub-board case 501 shown in Figure 51(a).

[0278] As shown in FIG. 51(a), the sub-substrate case 501 shown by the broken line is attached in a forward-inclined position relative to the rear side of the front door 2. Here, the "forward-inclined position" refers to a position in which the substrate case 501 is attached to the front door 2 so that the bottom plate Btp (which is also the case body of the sub-control substrate 502) of the sub-substrate case 501 faces the rear side of the front door 2, and when the front door 2 is closed, the upper part of the sub-substrate case 501 (more precisely, the bottom plate Btp) approaches the front door 2 and the lower part of the sub-substrate case 501 moves away from the front door 2 in the vertical direction VT. Also, as shown in FIG. 51(b), the solder surface SMF of the sub-control substrate 502 faces the bottom plate Btp of the sub-substrate case 501 inside the sub-substrate case 501 and is fixed parallel to it, so that the sub-control substrate 502 is also in a forward-inclined position. The back side of the solder surface SMF is a component mounting surface (surface portion) FS, but the various mounted components are not shown.

[0279] 51(b), when the sub-board case 501 is attached to the rear side of the front door 2 in a forward tilted position, even if a lead part or mounting screw falls off the sub-control board 502 and falls onto the lower plate SpD of the sub-board case 501, the lower plate SpD is tilted downward toward the front door 2, so that the lead part or mounting screw that has fallen onto the lower plate SpD is likely to roll toward the sub-control board 502. Therefore, since the lead part or mounting screw that has fallen onto the lower plate SpD is unlikely to block the heat dissipation hole wh, there is less risk of heat being trapped inside the sub-board case 501 and adversely affecting the various electronic components mounted on the sub-control board 502.

[0280] Furthermore, even if a lead component or mounting screw that falls onto the lower plate SpD rolls toward the sub-control board 502, as explained with reference to Figures 49 and 50, if the distance dg from the lower end edg of the sub-control board 502 to the inner surface Ms of the lower plate SpD and the distance dpml from the inner surface Ms of the lower plate SpD to the lowest component PML are determined based on the dimensions of each of the various lead components and mounting screws, it is possible to prevent the various lead components and mounting screws that fall off the sub-control board 502 from adversely affecting the various components mounted on the sub-control board 502.

[0281] In addition, taking into consideration that the lead components and mounting screws that have fallen onto the lower plate SpD roll toward the sub-control board 502, the length of the interval dw (see FIG. 51(b)) from the component mounting surface FS of the sub-control board 502 to the heat dissipation holes wh in the lower plate SpD may be determined based on the dimensions of each of the various lead components and mounting screws. For example, when determining the length of the interval dw based on the dimensions of each of the various lead components, it is desirable that the length of the interval dw is equal to or greater than the maximum dimensions (length L1, height h2, length L3) of the various lead components shown in FIGS. 48(a) to (c). In this way, by setting the length of the interval dw to be equal to or greater than the maximum dimensions of the various lead components, when a lead component that has fallen off the sub-control board 502 falls onto the lower plate SpD and rolls until it comes into contact with the component mounting surface FS of the sub-control board 502, the possibility that the lead component that has come into contact with the component mounting surface FS will reach the position of the heat dissipation holes wh can be reduced. In other words, the possibility that the dropped lead component will fall out of the sub-board case 501 through the heat dissipation holes wh can be reduced. In order to reduce the possibility that the mounting screw that has fallen off the sub-control board 502 will reach the position of the heat dissipation hole wh after dropping onto the lower plate SpD, the size of the interval dw should be set to be equal to or greater than the total length L4 of the mounting screw. By determining the size of the interval dw in this manner, the same advantages as in the case of the lead components described above can be obtained.

[0282] However, normally, when a lead component or mounting screw that has fallen off the sub-control board 502 falls onto the lower plate SpD and rolls until it comes into contact with the component mounting surface FS of the sub-control board 502, the size of the gap dw may be determined based on the dimensions of the lead component or mounting screw in a state in which the lead component in contact with the component mounting surface FS is in a stable position. Here, the "stable position" is, for example, a position in which the longest point (length L1, height h2, length L3) among the dimensions of the various lead components shown in Figures 48(a) to (c) is in contact with the sub-control board 502. To reduce the possibility of the various lead components reaching the position of the heat dissipation hole wh in this position, if the axial type lead component shown in Figure 48(a) falls off, the size of the spacing dw should be set to a diameter d1 or greater; if the radial type lead component shown in Figure 48(b) falls off, the size of the spacing dw should be set to a diameter d2 or greater; and if the radial type lead component shown in Figure 48(c) falls off, the size of the spacing dw should be set to a height h3 or greater.

[0283] Next, referring to Figures 52(a) and (b), the characteristics of the case where the sub-board case 501 is attached to the rear side of the front door 2 in a backward tilted position will be described. Here, Figure 52(a) is a side view of the slot machine 1 as seen from the right side, in which the position (attaching position) in which the sub-board case 501 is attached to the rear side of the front door 2 is shown by a dashed line. Also, Figure 52(b) is a schematic diagram of a partial cross section of the sub-board case 501 as seen from the right side in the attachment position of the sub-board case 501 shown in Figure 52(a).

[0284] As shown in FIG. 52(a), the sub-substrate case 501 shown by the broken line is attached in a forward-inclined position relative to the rear side of the front door 2. Here, the "backward-inclined position" refers to a position in which the substrate case 501 is attached to the front door 2 so that the bottom plate Btp (which is also the case body of the sub-control substrate 502) of the sub-substrate case 501 faces the rear side of the front door 2, and the front door 2 is closed, with respect to the vertical direction VT, the upper part of the sub-substrate case 501 (more precisely, the bottom plate Btp) is away from the front door 2 and the lower part of the sub-substrate case 501 is close to the front door 2. Inside the sub-substrate case 501, the sub-control substrate 502 is fixed parallel to the bottom plate Btp of the sub-substrate case 501, and therefore the sub-control substrate 502 is also in a backward-inclined position. The back side of the solder surface SMF is the component mounting surface (surface portion) FS, but the various mounted components are not shown.

[0285] 52(b), when the sub-substrate case 501 is attached to the rear side of the front door 2 in a backward tilted position, even if a lead part or mounting screw falls off the sub-control substrate 502 and falls onto the lower plate SpD of the sub-substrate case 501, the lower plate SpD is tilted downward toward the inside of the housing 5, so that the lead part or mounting screw that falls onto the lower plate SpD is likely to roll toward the heat dissipation hole wh. Therefore, since the lead part or mounting screw that falls onto the lower plate SpD is less likely to roll toward the sub-control substrate 502, it is possible to reduce the risk that the lead part or mounting screw that falls off the sub-control substrate 502 will adversely affect various components mounted on the sub-control substrate 502.

[0286] Furthermore, even if the lead parts or mounting screws that fall onto the lower plate SpD roll toward the sub-control board 502, as explained with reference to Figure 47, by appropriately determining the dimensions of the width W, length L and height H of the heat dissipation hole wh, it is possible to prevent the lead parts that have fallen off from the sub-control board 502 from falling outside the sub-board case 501 and causing adverse effects on other devices installed inside the housing 5 (for example, the hopper 51 and the power supply 55).

[0287] In the above explanation with reference to Figures 47 to 52, the sub-board case and sub-control board 502 have been given as examples, but the same may also be applied to main control board 110 and power supply board 550, as well as various other relay boards and the cases for those boards.
