  The respective reels 42L, 42M and 42R are respectively connected to stepping motors 61L, 61M and 61R, and the respective reels 42L, 42M and 42R are individually, ie, independently, driven by the respective stepping motors 61L, 61M and 61R. And can be rotationally driven. Since each of these reels 42L, 42M, 42R has the same configuration, here, the left reel 42L will be described as an example based on FIG. 6 is an assembly perspective view of the left reel 42L.

  The left reel 42L is provided with a cylindrical frame member 50 forming a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is stuck on the cylindrical frame member 50 via a pair of seal parts formed along the long side both sides of a belt so that the state where it was rolled may be maintained. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss 51 is formed at the center of the cylindrical frame member 50, and is attached to the drive shaft of the left reel stepping motor 61L via a disc-shaped boss reinforcing plate 52. Accordingly, when the drive shaft of the left reel stepping motor 61L rotates, the cylindrical skeleton member 50 is rotated about its drive shaft so that the left reel 42L revolves along the annular reel surface. It has become.

  The left reel stepping motor 61L is fixed to a side surface of a motor plate 53 disposed upright in the reel unit 41 (FIG. 3) by a screw 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which the light emitting element 55a and the light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56 b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42 L by a screw 57. The tip end portion 56 a of the sensor cut bun 56 is bent so as to be substantially perpendicular and aligned so as to be able to pass between the two elements 55 a and 55 b of the reel index sensor 55. Then, every time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the front end portion 56a of the sensor cut bun 56, and a detection signal is output to the main control device 131 described later each time. Therefore, the main controller 131 can confirm and correct the angular position of the left reel 42L every one rotation based on this detection signal.

  The stepping motor 61L is set to rotate once by giving a drive signal (also referred to as an excitation signal or an excitation pulse, hereinafter the same) of 504 pulses, for example, and the rotational position of the stepping motor 61L, that is, the left by this excitation pulse. The rotational position of the reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, 42R, a plurality of, specifically, 21 symbols are drawn in the long side direction (surrounding direction). Therefore, it takes 24 pulses (= 504 pulses / 21 symbols) to switch from one symbol to the next symbol at a predetermined position. And, by the number of pulses from the time when the detection signal of the reel index sensor 55 is output, it can be recognized which symbol is in a visible state from the display window 31L or any symbol can be visually recognized from the exposure window 31L. It is possible to carry out control to set the status as normal.

  Of the symbols attached to each of the reels 42L, 42M, 42R, the number of symbols visible in the whole through the display windows 31L, 31M, 31R is mainly determined by the vertical length of the display windows 31L, 31M, 31R It is limited to a predetermined number. In the present embodiment, three reels are provided. Therefore, when all the reels 42L, 42M, 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  Here, the symbols attached to the respective reels 42L, 42M, 42R will be described. FIG. 7 shows an arrangement of symbols drawn on a belt wound on each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, 21 symbols are provided in a row on each of the reels 42L, 42M, 42R. Although the numbers 1 to 21 are assigned corresponding to the respective reels 42L, 42M, 42R, this is for convenience of description and is not actually attached to the reels 42L, 42M, 42R. . However, the following description will be made using the corresponding numbers.

  As the symbols, there are a "7" symbol (for example, the left belt twentieth) and a "youth" symbol (for example, the left belt nineteen) as a first special symbol for shifting to a big bonus game. In addition, there is a "BAR" symbol (for example, the 14th left belt) as a second special symbol for shifting to the regular bonus game. In addition, there is a "replay" symbol (for example, the 11th left belt) as a third special symbol for shifting to the replay game. In addition, the "watermelon" symbol (for example, the left belt ninth), the "bell" symbol (for example, the left belt eighth), the "cherry" symbol (for example, the left) There is a belt fourth). And as shown in FIG. 7, in the belts wound around the respective reels 42L, 42M, 42R, the number and arrangement order of various symbols are completely different.

  The respective reels 42L, 42M, 42R of the reel unit 41 are an example of variable display means for variably displaying identification information, and constitute a main display portion. However, the variable display means may have a configuration other than this. For example, other mechanical reels may be used, such as rotating the belt instead of rotating it, and liquid crystal displays and dot matrix displays may be used instead of or in addition to the mechanical reels. It is also possible to provide one for variably displaying identification information by means of electrical display such as, and in this case, it is possible to make the display form have rich variations.

  A total of five combination lines, three in parallel in the lateral direction and two in diagonal direction, are attached to the game panel 30 so as to connect the display windows 31L, 31M, 31R. Of course, the maximum number of combination lines may be 6 or more, or may be less than 5, and the maximum number of combination lines may be changed according to a predetermined condition. The effective line display portions 32, 33, 34 are provided on the left side of the display windows 31L, 31M, 31R as viewed from the front corresponding to the respective combination lines. The first effective line display unit 32 is displayed and notified by lighting or the like when the center horizontal line (center line) of the combination lines is activated. The second effective line display unit 33 is displayed and notified by lighting or the like when the upper and lower horizontal lines (upper and lower lines) of the combination lines are activated. The third valid line display unit 34 is displayed and notified by lighting or the like when a pair of oblique lines (down-right line and up-right line) of the combination lines are activated. When a symbol is stopped in a predetermined combination on the activated combination line, that is, the activated line, a prize is awarded, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the number of payouts for each symbol when winning will be described. With regard to the small character pattern, if the "watermelon" symbol is aligned with the left, middle and right on the effective line, 15 medals are paid out, and the "bell" symbol is aligned with the left, middle and right on the effective line In the case where eight medals are paid out and the "cherry" symbol on the left reel 42L is stopped on the effective line, two medals are paid out. That is, the "cherry" symbol of the middle reel 42M and the right reel 42R is irrelevant to the medal payout. In addition, in the case of the "cherry" symbol, medals are paid out independently of the combination with other symbols, so a plurality of effective lines of the left reel 42L overlap (specifically, upper or lower) " When the pattern of "cherry" is stopped, medals are paid out by multiplying the number of the overlapping effective lines, and as a result, four medals are paid out in the present embodiment.

  Also, for other symbols, if the “7” symbol or “youth” symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, middle and right on the active line with the same symbol Even if the "BAR" symbol, which is a combination of the 15 medal payouts and the second special symbol (regular bonus symbol), is aligned with the left, middle and right on the effective line, 15 medal payouts are also made. In addition, in this embodiment, although the case where a "7" symbol and a "cherry" symbol are simultaneously materialized may arise, for example, the medal payout in this case is 15 sheets. This is because the upper limit number in one medal payout is set to 15.

  Furthermore, when the "replay" symbol which is a combination of the third special symbol is aligned with the left, middle and right on the effective line, the medal payout is not performed. In other cases, that is, when the "cherry" symbol of the left reel 42L does not stop on the effective line, and when the same symbol as the left, middle or right does not align on the effective line, no medal is paid out.

  On the lower left side of the game panel 30, there is provided a start lever 71 operated to cause the reels 42L, 42M, 42R to start rotating simultaneously (not necessarily simultaneously). The start lever 71 constitutes start operation means or start operation means operated to start rotating the reels 42L, 42M, 42R, that is, to start variable display. The start lever 71 is a lever that the player manually presses to start the game and automatically returns to the original position after the player's hand is released. When the start lever 52 is operated while medals are inserted, the reels 42L, 42M, 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 operated to individually stop the rotating reels 42L, 42M, 42R are provided. The respective stop switches 72, 73, 74 are disposed immediately below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop variable display based on the rotation of the reels 42L, 42M, 42R. Each stop switch 72, 73, 74 can be stopped when the reels 42L, 42M, 42R rotate at a constant speed, and a lamp (not shown) is turned on to display the stop operation during such a state. It is informed that it is possible and is turned off when the rotation is stopped.

  On the lower right side of the display windows 31L, 31M, 31R, a medal insertion slot 75 for inserting a medal as an investment value is provided. The medal insertion slot 75 constitutes an input means for inputting an investment value. Also, focusing on the point that the medal insertion slot 75 involves an operation of inserting the medal directly by the player, it can be said to constitute a direct input means for directly inputting the investment value.

  The medal inserted from the medal insertion slot 75 is guided to either the storage passage 81 or the discharge passage 82 by a selector 84 provided on the back of the front door 12 as passage switching means. That is, the selector 84 is provided with the medal passage switching solenoid 83, which is on the discharge passage 82 side when the medal passage switching solenoid 83 is not excited, and is switched to the storage passage 81 at the time of excitation.

When the change-over switch 80 is in the OFF state, the "direct mode" is set such that a surplus inserted medal or an acquired medal at the time of winning is paid out as a real medal. When the credit mode is switched to the direct mode and there is a credit medal, the credit medal for that amount is paid out as a real medal. Thus, the player can play the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for switching the handling type of the insertion value and the gaming value. Also, focusing on the function of paying out the credited virtual medal as a real medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game value. In addition to being configured to switch between the "credit mode" and the "direct mode" by the operation of the changeover switch 80, it is always set as the "credit mode" and the virtual medal stored and stored is paid out when the changeover switch 80 is operated. It may be made to function as a settlement switch only.

Thus, even if the screw 223 can be removed from the inside of the back plate 11c, the fixed base plate 211 can not be removed unless the screw 233 is removed from the outside of the back plate 11c. In short, in the present embodiment, not only the removal of the fixed base plate 211 is made difficult by incorporating the cap body 224 into the screw 223 screwed on the front side of the fixed base plate 211, but the fixed base from the outside of the back plate 11c. By screwing the plate 211, removal of the fixed base plate 211 is made more difficult.

  On the other hand, in the movable base plate 212, side plate portions 242 and 243 are formed on long sides (upper and lower ends in the figure) of the bottom plate 241, and the side plate 242 is formed on one side (left side in the figure) of the short side. , 243 to form a stepped portion 244. The side plate portions 242 and 243 and the step portion 244 have a height matched to the main controller 131. At the front end of the side plate portions 242 and 243, return portions 242a and 243a which are formed to be bent inward are provided at a plurality of places (six places in this embodiment). The right end portion of the bottom plate portion 241 serves as a substrate mounting port 245 for slidingly mounting the main controller 131. In this case, the main controller 131 is mounted from the substrate mounting port 245 and is slid until it hits the step portion 244, whereby the main controller 131 is mounted at a predetermined position on the movable base plate 212.

  The stepped portion 244 has an opening 246 opened in the sliding direction of the main controller 131, a locking hole 247 formed in the upper surface (upper surface relative to the bottom plate 241), and a locking hole A pair of through holes 248 formed so as to sandwich 247 is provided. The upper surface portion of the step portion 244 provided with the locking hole portion 247 and the through hole 248 is a sticking surface of a sealing seal S described later, and a surrounding frame 331 is formed so as to surround the sticking surface.

  A pivot shaft 249 is provided at the left end of the movable base plate 212, and a pivot hole 249a is formed in the pivot shaft 249. In such a configuration, the pivoting portion 216 of the fixed base plate 211 and the pivoting shaft portion 249 of the movable base plate 212 are aligned, and in that state, the shaft support 216 and the shaft holes 216a and 249a of the pivoting shaft portion 249 are columns. The pin 217 is inserted. Thus, the movable base plate 212 is rotatably supported by the fixed base plate 211.

  The hole diameter (design dimension) of the shaft hole 216 a of the shaft support portion 216 is slightly smaller than the outer diameter of the support pin 217, and the hole diameter of the shaft hole 249 a of the pivot shaft portion 249 is slightly larger than the outer diameter of the support pin 217. When the support pin 217 is inserted, the support pin 217 is press-fit into the shaft hole 216 a of the support portion 216. At this time, the head of the support pin 217 is flush with the support portion 216, or the state where the support pin 217 is sunk into the shaft hole 216a, and the support pin 217 can not be pulled out and removed. Therefore, although the movable base plate 212 can be rotated with respect to the fixed base plate 211, separation (uncoupling) is impossible. However, the hole diameter (design dimension) of the shaft hole 249a of the rotation shaft portion 249 is slightly smaller than the outer diameter of the support pin 217 contrary to the above configuration, and the support pin 217 is the shaft hole of the rotation shaft portion 249 It may be configured to be pressed into 249a. What is essential as a configuration of the rotation shaft portion is that the movable base plate 212 can be rotated with respect to the fixed base plate 211 and can not be separated (connection can not be released).

  On the bottom plate portion 241, a plurality of (four in the present embodiment) sealing coupling portions 251 constituting the first sealing portion are erected so as to be aligned in a vertical row. The sealing joint portion 251 has a cylindrical shape whose bottom is closed by the bottom plate portion 241, and is opened only on the front side of the drawing. The configuration of the first sealing unit including the sealing joint unit 251 will be described later.

  In the vicinity of the step portion 244 of the movable base plate 212, a key attachment bracket 261 having a key insertion hole 261a at its tip end portion is attached and fixed. A root portion of the key mounting bracket 261 is fixed to the movable base plate 212 by a fixing tool such as a screw (not shown).

  Next, the configuration of main controller 131 will be described in detail. FIG. 13 is an exploded perspective view showing each of the case bodies 271 and 272 and the main substrate 273 constituting the main control device 131 in an enlarged manner.

  A wiring pattern (not shown) is provided on the main substrate 273, and various electronic components including an IC chip 274 such as a CPU and a ROM, an input / output connector 275, a test connector 276 and the like are mounted. In particular, as the IC chip 274, a vertical element such as a so-called ZIP (Zigzag In-line Package) type structure or an SIP (Single In-line Package) structure, which is mounted with the chip standing up to the substrate surface, is employed. On the side of the chip, identification information such as manufacturer and part number, unique information, and the like are printed. The main substrate 273 is fixed to the front case body 271 by screws 277 through a plurality of small holes provided at corner portions.

  The front case body 271 has a main substrate accommodating portion capable of accommodating a relatively tall electronic component or the like on the main substrate 273, and a stepped portion 281 lower by one step is formed in the peripheral portion. The stepped portion 281 is formed with a plurality of connector insertion holes 282 for inserting the input / output connector 275 on the main substrate 273. Reference numeral 283 denotes an opening passing through the inspection connector 276 on the main substrate 273. Although illustration is omitted, a large number of vent holes are formed in the ceiling portion of the front case body 271 or the like.

  Further, at each of the upper and lower edges in the long side of the front case body 271, there are provided projecting ridges 285 extending linearly along the side wall of the front case body 271. The elongated holes 286 are provided in a line at predetermined intervals.

  A vertically long rectangular notch angular hole 290 is provided at the left end of the front case body 271 (on the left side of the main substrate accommodation portion), and the notch angular hole 290 has a plurality of first sealing portions. Seal coupling portions 291 (four in the present embodiment) are provided so as to be arranged in a single vertical line. The peripheral configuration is shown enlarged in FIG. The seal joint portion 291 has a cylindrical shape, and is connected to the front case body 271 by connection portions 292 on both left and right sides. The seal joint portion 291 can be cut away from the front case body 271 by cutting the joint portion 292. Similarly, a plurality of (two in the present embodiment) sealing joint portions 293 constituting the second sealing portion are provided in the notch corner hole portion 290 so as to sandwich the plurality of sealing joint portions 291. The sealing joint portion 293 has a cylindrical shape, and is connected to the front case body 271 by a connecting portion 294. By cutting the connecting portion 294, the seal bonding portion 293 can be cut away from the front case body 271.

  In such a case, since the sealing coupling portions 291 and 293 constituting the first and second sealing portions are provided in the notch corner holes 290 formed in the front case body 271, the sealing coupling portions 291 and 293 protrude to the side of the substrate case. Unlike the conventional general configuration in which the sealing portion is provided, there is no inconvenience such as the sealing joint portions 291 and 293 protruding to the side and becoming an obstacle. In addition, since the seal bonding portions 291 and 293 do not extend laterally, there is no possibility that the seal bonding portions 291 and 293 may be hit and damaged or the like when the main control device 131 is handled alone.

  The left end portion of the front case body 271 is a leading portion when the main controller 131 is slide-mounted to the movable base plate 212, and a locking claw portion 295 is provided at the front end portion and a locking claw A pair of screw holes 296 are provided to sandwich the portion 295. When the main controller 131 is mounted on the movable base plate 212, the locking claws 295 are locked in the locking holes 247 provided on the movable base plate 212. Further, the screw holes 296 and the through holes 248 provided in the movable base plate 212 are aligned, and in this state, the small screws 297 are screwed into the through holes 248 and the screw holes 296.

  On the left side of the notch corner hole 290 of the front case body 271, a surrounding frame 332 is formed which defines the application surface of the sealing seal S. When the main controller 131 is mounted on the movable base plate 212, the enclosure frame 332 of the front case body 271 and the enclosure frame 331 formed on the movable base plate 212 are integrated to form an enclosure of a rectangular frame as a whole. A frame is to be formed.

  Returning to the description of FIG. 13, at the right end of the front case body 271, a plurality (two in the present embodiment) of seal joint portions 301 constituting a third seal portion are provided. The sealing joint portion 301 has a cylindrical shape, and is connected to the front case body 271 by a connecting portion 302. By cutting the connecting portion 302, the seal connecting portion 301 can be cut away from the front case body 271.

  Furthermore, a key mounting bracket 305 is attached and fixed to the right end of the front case body 271. A root portion of the key mounting bracket 305 is fixed to the front case body 271 by a fixing tool such as a screw (not shown). The front end portion of the key mounting bracket 305 is bent diagonally outward, and a key insertion hole 305a is formed in the bent portion (see FIG. 17 and the like).

  On the other hand, in the back case body 272, on the upper and lower sides in the figure on both sides of the bottom plate portion 311, a plurality of hooking portions 312 rising in the substrate height direction and having L-shaped tip portions are provided at predetermined intervals. It is done. The hooking portions 312 are provided at the same intervals as the long holes 286 of the front case body 271, and both case bodies 271 and 272 are formed by the long holes 286 of the front case body 271 and the hooking portions 312 of the back case body 272. Is to be assembled.

  FIG. 18 (an end view taken along the line B-B in FIG. 8) shows an assembled structure of the front case body 271 and the back case body 272. As shown in FIG. 18, the hook portion 312 of the back case body 272 is inserted into the long hole 286 of the front case body 271, and the hook portion 312 is formed in the long hole 286 on the front case body 271 side in that state. The locking portion 286a is locked. As a result, the front case body 271 is held without floating relative to the back case body 272. Incidentally, FIG. 18 illustrates a state in which the main control unit 131 is assembled to the pedestal device 210 and the front case body 271 can not slide laterally with respect to the back case body 272. If the front case body 271 is slid in the right direction in FIG. 18 and then lifted upward after that, the front case body 271 can be separated from the back case body 272 (FIG. 18). The front case body 271 is moved along the inside arrow P).

  In the movable base plate 212, a return portion 212a is provided at the left end in FIG. 18, and the return portion 212a is below the pivoting portion 216 of the fixed base plate 211 (in fact, in the hole 216b shown in FIG. 12). It is configured to enter. Therefore, even if the support pin 217 is cut off in the middle or the support pin 217 is pulled out, the movable base plate 212 does not lift up with respect to the fixed base plate 211 by itself.

  Returning to the description of FIG. 13 again, a pair of upper and lower extending portions 314 a and 314 b are provided at the left end of the back case body 272 so as to extend leftward than the bottom plate portion 311. Each of the sections 314a and 314b is provided with a sealing joint 315 that constitutes a second sealing section. The sealing joint portion 315 has a cylindrical shape in which the bottom portion is closed in the same plane as the bottom plate portion 311, and is opened only on the front side of the drawing. The extension parts 314a and 314b are provided separately in the upper and lower direction, and the space between the two extension parts 314a and 314b is for avoiding interference with a plurality of sealing coupling parts 251 provided on the movable base plate 212. It is an empty space.

  A key attachment 316 having a key insertion hole 316a at its tip is attached and fixed to the upper extension 314a in the figure. A root portion of the key attachment 316 is fixed to the back case body 272 by a fixing tool such as a screw (not shown).

  Further, at the right end portion of the back case body 272, a plurality (two in the present embodiment) of seal joint portions 317 which constitute the third seal portion are provided. The seal connecting portion 317 is connected to the back case body 272 by a connecting portion 318. By cutting the connecting portion 318, the sealing joint 317 can be cut away from the back case body 272.

  Here, a sealing structure for suppressing unauthorized removal of the main control device 131 and the pedestal device 210 will be described. In the present embodiment, three types of sealing portions having different sealing structures are provided, and for convenience, they are referred to as a first sealing portion, a second sealing portion, and a third sealing portion, which will be sequentially described. FIG. 19 corresponds to an end view along the line C-C in FIG. 8 and shows a cross-sectional structure of the first sealing portion. FIG. 20 is an end view taken along the line D-D of FIG. 8 and shows a cross-sectional structure of the second sealing portion. FIG. 21 is an end view taken along the line E-E of FIG. 8 and shows a cross-sectional structure of the third sealing portion.

  First, the configuration of the first sealing unit will be described based on FIG. In FIG. 19, (a) shows a state before sealing, (b) shows a sealing state, and (c) shows a state of unsealing. The first sealing portion can be sealed by joining the sealing joint 291 provided on the front case body 271 and the sealing joint 251 provided on the movable base plate 212. The description will be made in another way by rephrasing the side coupling portion 291 ′ ′ and the latter as the “receiving side coupling portion 251”.

  As shown in FIG. 19A, the insertion side coupling portion 291 of the front case body 271 is formed with a hole 291a (for convenience, referred to as an upper hole) penetrating in the vertical direction, and the movable base A hole 251 a (referred to as a lower hole for convenience) coaxially communicating with the upper hole 291 a is formed in the receiving side connection portion 251 of the plate 212. A stepped portion 291b is provided at the inlet of the upper hole 291a, and an enlarged diameter portion 251b having a diameter larger than that of the upper hole 291a is provided at the inlet of the lower hole 251a.

  Reference numerals 251 c and 291 c denote semicircular return parts respectively provided in the receiving side connection part 251 and the insertion side connection part 291 (the return part 251 c is in front of the main controller 131 in the sliding direction, and the return part 291 c is The coupling portions 251 and 291 abut on the return portions 251c and 291c. The opposing joint surfaces of the coupling portions 251 and 291 are hidden by the return portions 251 c and 291 c.

  The connecting portion 292 connecting the insertion side connecting portion 291 has a substantially reverse trapezoidal shape in which the upper side is long and the lower side is short as shown by a hidden line (dotted line) in the figure. In this case, in particular, the end opposite to the insertion side coupling portion 291 in the coupling portion 292 is formed in an obliquely tapered shape so as to be inclined outward toward the upper side.

  When the sealing process is performed, as shown in FIG. 19B, the holes 291a and 251a of the insertion-side coupling portion 291 and the receiving-side coupling portion 251 are made of, for example, a synthetic resin in a substantially hollow cylindrical shape. The sealing pin member 321 is inserted. As shown in FIG. 16, the sealing pin member 321 has a hollow cylindrical portion 321a, a flange-like head portion 321b, and an elastically deformable locking claw portion 321c provided at the cylindrical portion 321a, for example, at two places. In the normal state, the locking claw portion 321c protrudes outward beyond the outer periphery of the cylindrical portion 321a, and by applying an external force, the locking claw portion 321c can be inserted into the cylindrical portion 321a. There is. Identification information (for example, an identification code) of each main controller 131 is attached to the head 321 b of the sealing pin member 321.

  When the sealing pin member 321 is inserted, the locking claw portion 321c of the sealing pin member 321 is elastically deformed so that the head portion 321b is inserted until it hits the step portion 291b at the entrance of the upper hole portion. At this time, when the locking claw portion 321c of the sealing pin member 321 reaches the enlarged diameter portion 251b of the lower hole portion 251a, the locking claw portion 321c is raised, and the rear end surface of the locking claw portion 321c is on the insertion side The distal end surface of the portion 291 is locked. Thereby, the sealing of the first sealing portion is completed, and the dropping of the sealing pin member 321 after sealing is prevented.

  In order to release the seal of the first sealing portion when a defect occurs in the main controller 131 or during an inspection, as shown in FIG. 19C, the insertion side coupling portion 291 and the front case body 271 are separated. The connecting portion 292 to be connected is cut by a tool such as a nipper. Only the tip end portion of the sealing pin member 321 is inserted into the receiving side coupling portion 251, and since the respective members 251 and 321 are not in a locked state, the insertion side coupling portion is cut by cutting the coupling portion 292. 291 and the sealing pin member 321 can be easily cut away from the front case body 271. At this time, as described in FIG. 19A, since the connecting portion 292 has a substantially inverted trapezoidal shape in which the upper side is long and the lower side is short, it is easy to insert a tool such as a nipper. In addition, since the end on the opposite side to the insertion side coupling portion 291 in the coupling portion 292 is formed in an obliquely tapered shape so as to be inclined outward toward the upper side, the insertion side after cutting the coupling portion 292 The joint portion 291 and the sealing pin member 321 are easily pulled upward.

  The cut-out insertion side coupling portion 291 and the sealing pin member 321 can be easily separated by elastically deforming by pressing the locking claw portion 321c of the sealing pin member 321 with a finger or a tool or the like. The separated sealing pin member 321 does not have any deformation or destruction, and the same sealing pin member 321 is used for the next sealing.

  As described above, since the identification information of each main controller 131 is attached to the head portion 321 b of the sealing pin member 321, after the sealing process is performed again by reuse of the sealing pin member 321, the identification information is By checking, it can be checked whether the sealing process has been performed according to the regular procedure.

  When the sealing of the first sealing portion is released, the location to be cut (broken) is only the connecting portion 292 on the front case body 271 side, and the sealing counterpart side, that is, the movable base plate 212 in this case is not broken anywhere. That is, even if the sealing process between the front case body 271 and the movable base plate 212 and the release thereof are repeatedly performed, the movable base plate 212 is not broken and the sealing history does not remain. Therefore, even when the main control device 131 is replaced, the movable base plate 212 (i.e., the pedestal device 210) can be reused as it is.

  In the first sealing unit, which one of the four sealing locations is to be used is determined in advance in order, for example, sealing is sequentially performed one by one from the top in FIG. The seal history remains in the seal portion where the cutting process (destruction process) is performed after the sealing, and it is possible to easily confirm how many times the sealing process has been performed in the past. The fact that the sealing process has been performed at each sealing location is recorded on a sealing record slip attached to the surface portion or the like of the front case body 271. For example, the date and time of implementation of the sealing process, the name of the sealing operator, and the like are recorded in the sealing record slip for each sealing location. Similarly, the sealing record may be left for the second sealing unit and the third sealing unit described later.

  Next, the configuration of the second sealing unit will be described based on FIG. The second sealing portion can be sealed by the combination of the sealing bonding portion 293 provided on the front case body 271 and the sealing bonding portion 315 provided on the back case body 272. The description will be continued with the side coupling portion 293 "and the latter as" receiving side coupling portion 315 ".

  As shown in FIG. 20, in the insertion side coupling portion 293 of the front case body 271, a hole portion 293a (referred to as an upper hole portion for convenience) penetrating in the vertical direction is formed. A hole 315 a (referred to as a lower hole for convenience) coaxially communicating with the upper hole 293 a is formed in the receiving side coupling portion 315. The upper hole portion 293a is formed with a large diameter portion for housing the head of a sealing screw 323 described later, and a small diameter portion smaller than that. A female screw portion is formed in the lower hole portion 315a. Then, the sealing screw 323 is screwed into the holes 293a and 315a of the insertion side coupling portion 293 and the reception side coupling portion 315, whereby the sealing of the second sealing portion is completed. The sealing screw 323 is constituted by a so-called breaking screw having a fractured portion (diameter-reduced portion) which is easily broken at an intermediate portion, and a predetermined torque or more is applied when screwing the screw 323 by a tightening tool such as a driver. The fracture portion is fractured. Due to this breakage, once the sealing screw 323 is screwed into the hole 293a, 315a, it is impossible to loosen the screw 323 thereafter.

  In order to release the seal of the second sealing portion, the connecting portion 294 connecting the insertion side connecting portion 293 and the front case body 271 is cut with a tool such as a nipper (X1 part in the figure) and the receiving side connecting portion The bottom of 315 is cut with a tool such as a nipper (X2 part in the figure). That is, the cutting process in the vertical direction and the cutting process in the horizontal direction orthogonal thereto are performed. As a result, the sealing screw 323 can be separated from the case bodies 271 and 272 to unseal the second sealing portion.

  Next, the configuration of the third sealing unit will be described based on FIG. The third sealing portion can be sealed by the combination of the sealing bonding portion 301 provided in the front case body 271 and the sealing bonding portion 317 provided in the back case body 272. The description will be continued with the side coupling portion 301 ′ ′, and the latter as the “receiving side coupling portion 317”.

  As shown in FIG. 21, in the insertion-side coupling portion 301 of the front case body 271, holes 301 a (referred to as upper holes for convenience) penetrating in the vertical direction are formed. In the receiving coupling portion 317, a hole 317a (for convenience, referred to as a lower hole) coaxially communicating with the upper hole 301a is formed. The upper hole portion 301a is formed with a large diameter portion for housing the head of a sealing screw 325 described later and a small diameter portion smaller than that. A female screw is formed in the lower hole 317a. Then, the sealing screw 325 is screwed into the holes 301a and 317a of the insertion side coupling portion 301 and the reception side coupling portion 317, whereby the sealing of the third sealing portion is completed. The sealing screw 325 can be screwed with a tightening tool such as a driver in the tightening direction, but can not be loosened in the loosening direction, and is constituted by so-called one-way screws (also referred to as one-way screws) Once the screw 325 is screwed into the holes 301a and 317a, the screw 325 can not be loosened thereafter.

  In order to release the seal of the third sealing portion, the connecting portion 302 connecting the insertion side connecting portion 301 and the front case body 271 and the connecting portion 318 connecting the receiving side connecting portion 317 and the back case body 272 Together and cut with a tool such as a nipper (X3 part in the figure). As a result, the sealing screw 325 can be separated from the case bodies 271 and 272 to unseal the third sealing portion.

  Although in the above description, the sealing process is performed on both the second sealing unit and the third sealing unit, in reality, only one of these sealing units is subjected to the sealing process. For example, when the slot machine 10 is manufactured, the second sealing portion is sealed when the main substrate 273 is accommodated in the substrate box (cases 271 and 272). After that, when the main control device 131 is recovered for inspection or the like, the second sealing unit is opened, and the third sealing unit is sealed after the inspection or the like.

  On the other hand, as shown in FIG. 9 and the like, on the left side of the main substrate unit 200, the seal attachment surface surrounded by the movable base plate 212 and the enclosure frames 331 and 332 of the front case body 271 A rectangular sealing seal S is attached so as to straddle the case body 271. Once the seal seal S is applied, it is peeled off from the seal label once it is peeled off, and the adhesive can not be adhered again, and the mark remains when the seal seal S is peeled off, so the movable base It can be checked whether or not the main control unit 131 has been removed from the plate 212. In the state where the main controller 131 is coupled to the movable base plate 212, the locking hole 247 and the through hole 248 formed in the movable base plate 212, and the locking claw 295 and the screw formed in the front case body 271. The holes 296 are in a mated state, such that they are obscured by the sealing seal S.

  As described above, the seal seal S has a configuration that can not be re-applied, but there is a fraudulent act such as sticking another seal member (sticking piece) after peeling off the seal seal S, and such fraudulent action is suppressed In addition, it is considered that suppressing the peeling action of the seal seal S is one measure. Therefore, in the present embodiment, as a measure against unauthorized peeling of the seal seal S, the seal sticking surface consisting of the surface of the movable base plate 212 and the surface of the front case body 271 is surrounded by the enclosures 331 and 332, and further the enclosure 331, In the vicinity of the base end portion 332, that is, the vicinity of the root portion (peripheral portion of the seal attaching surface) is formed in a curved shape. Specifically, by forming a tapered surface in accordance with the long side portion of the sealing seal S, the seal sticking surface is formed to be curved.

  When the seal seal S is attached to the seal attachment surface, the peripheral portion of the seal seal S enters the curved portion of the seal attachment surface, and it becomes difficult to hook the peripheral portion of the seal seal S with a nail or the like. Therefore, the suppression effect with respect to peeling off sealing seal S unfairly is acquired. In the configuration of the present embodiment, the seal application surface surrounded by the enclosures 331 and 332 substantially matches the size of the seal seal S, and in the state where the seal seal S is attached, the peripheral portion of the seal seal S is almost There will be no gap. Therefore, it is even more difficult to hook the peripheral portion of the seal seal S with a nail or the like to peel it off.

  As shown in FIG. 22, when the main control unit 131 is mounted on the base unit 210, the key mounting bracket 261 provided on the movable base plate 212 and the key mounting bracket 316 provided on the back case body 272 of the main control unit 131. And the key member K1 such as a padlock is attached through the key insertion portions 261a and 316a of the key attachment fittings 261 and 316. Furthermore, in a state in which the fixed base plate 211 and the movable base plate 212 are superimposed, the key attachment bracket 219 provided on the fixed base plate 211 and the key attachment bracket 305 provided on the front case body 271 face each other. A key member K2 such as a padlock is attached through the key insertion portions 219a and 305a of the key attachment brackets 219 and 305. The unlocking key of the key members K1 and K2 is managed by the game hall manager or the like.

  In such a configuration, the movable base plate 212 can not be rotated relative to the fixed base plate 211 unless the key member K2 is removed. Further, even if the key member K2 is removed, the main control device 131 can not be removed from the movable base plate 212 unless the key member K1 is removed. Therefore, the master controller 131 can not be removed unless the owner of the unlocking key is properly managed.

  Each sealing unit described above is originally configured to be cut (destructible), and its main purpose is to leave the unsealing history. Therefore, it is deterred against fraudulent acts such as taking away (stealing) the main control device 131. Although the effect can not be exhibited, in the above-described configuration in which the key members K1 and K2 are attached, the suppression effect can be exhibited with respect to the removal of the main control device 131 (can be a measure to prevent theft of the main control device 131).

  The tip end portions of the key mounting brackets 219 and 305 are provided so as to escape from the main control device 131 to be inclined. Thereby, even if the key member K2 is attached immediately to the side of the front case body 271, the key member K2 can be attached without being disturbed by the front case body 271 or the like.

  Next, a procedure for removing the main control device 131 from the pedestal device 210 in a state where the main substrate unit 200 is attached to the back plate 11c of the housing 11 will be described based on FIG. (A) of FIG. 23 shows a state in which the movable base plate 212 is superimposed on the fixed base plate 211 (that is, a normal use state), and (b) shows the movable base plate with respect to the fixed base plate 211. (C) shows a state in which the main control unit 131 is slid from the movable base plate 212 while the movable base plate 212 is rotated. In FIG. 23, the lower side is the slot machine front, and the upper side is the slot machine rear.

  In the state of (a), the fixed base plate 211 and the movable base plate 212 overlap, and the locking claw portion 218 of the fixed base plate 211 is the main controller 131 (in fact, the front case body 271). It is locked on the top of the Although illustration is omitted for convenience, the key members K1 and K2 are attached to the main board unit 200 as described above, and the movable base plate 212 can not rotate with respect to the fixed base plate 211. At this time, the surface portion of the main controller 131 faces the front side of the slot machine 10, and the main substrate surface, that is, the mounting surface of the IC chip or the like is viewed from the front.

  Further, when the movable base plate 212 shown in (b) is pivoted, the key member (at least the key member K2 of FIG. 22) is removed and the locking of the locking claw portion 218 of the fixed base plate 211 is released. In the state, the movable base plate 212 is rotated relative to the fixed base plate 211 as illustrated. At this time, the movable base plate 212 is pivoted about 90 degrees at maximum about the pivot pin 217, and the pivoting end portion side of the main control device 131 is pulled closer to the near side together with the movable base plate 212. In this state, it is possible to visually recognize the back surface side of the main control device 131 (that is, the back surface of the main substrate 273), and it is possible to confirm whether or not there are abnormalities or irregularities in various electronic components and electrical wiring.

  When the movable base plate 212 and the main controller 131 are rotated with respect to the fixed base plate 211 as shown in (b), the main controller 131 is viewed from an oblique side from the state viewed from the front side. Transition to the state. Therefore, even if it is information or the like attached to a difficult-to-view spot directly in front of main controller 131, that is, information or the like attached to an upright surface portion substantially perpendicular to the substrate surface of main substrate 273, the visible movement is easy It can be done. For example, in the vertical IC chip 274 mounted on the main substrate 273, information such as the manufacturer and the product number printed on the side surface of the chip can be easily viewed.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIG. 5 etc., the front space of the main controller 131 is open, and there is no problem in the forward movement of the movable base plate 212. It does not occur. Even if a device or mechanism projecting to the rear of the slot machine is provided on the back of the front door 12, the front space of the main controller 131 is opened as the front door 12 is opened, and the pivoting operation of the movable base plate 212 is also performed. There is no hindrance to

  Further, when the main controller 131 shown in (c) of FIG. 23 slides, the key member (the key member K1 of FIG. 22) is removed and the first sealing portion (seal between the movable base plate 212 and the front case body 271) ) Is opened. Further, the locking of the locking claw portion 295 provided at the left end of the front case body 271 and the screw fixation at the screw hole portion 296 are released. Then, the main controller 131 slides on the movable base plate 212 in this state. As a result, the main control unit 131 can be detached from the pivoting end portion side of the movable base plate 212 (the substrate attachment port 245 in FIG. 12).

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main controller 131 is mounted with a microcomputer having a CPU 151 as an arithmetic processing means. In addition to the power supply device 161 provided inside the power supply box 121, the CPU 151 is connected with a clock circuit 154 that outputs a rectangular wave of a predetermined frequency, an input / output port 155, and the like via an internal bus. The main controller 131 functions as a main base incorporated in the slot machine 10.

  On the input side of the main controller 131, a start detection sensor 71a for detecting the operation of the start lever 71, stop detection sensors 72a, 73a and 74a for individually detecting the operations of the respective stop switches 72, 73 and 74, and a medal insertion slot Switch to detect the operation of the inserted medal detection sensor 75a that detects medals inserted from 75, the credit insertion detection sensor 77a, 78a, 79a that individually detects the operation of each of the credit insertion switches 77, 78, 79, and the changeover switch 80 A detection sensor 80a, a reel index sensor 55 for individually detecting the rotational position (origin position) of each reel 42, a payout detection sensor 91a for detecting medals dispensed from the hopper device 91, and a reset detection sensor for detecting the operation of the reset switch 123 123a, set in the setting key insertion hole 124 Chromatography are connected various sensors such as setting the key detection sensor 124a for detecting that it has been inserted, the signals from these various sensors are outputted to the CPU151 through the input and output ports 155.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 from the medal insertion slot 75 to the hopper device 91 is configured such that medals can pass in one row. Then, the first passage is provided in the storage passage 81, and the second sensor and the third sensor are in proximity to the downstream side further away than the width of the medal (the extent to which the state where the same medal is simultaneously detected in at least one time occurs) And the first to third sensors constitute an inserted medal detection sensor 75a. The main control unit 131 monitors the time from the first sensor to the second sensor, and when the elapsed time exceeds a predetermined time, it is regarded as a medal jam or an error and is regarded as an error. If an error occurs, the error notification is performed and the operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second and third sensors are turned on and off, both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. It is determined that the medals are taken in normally only when the third sensor is on and the second and third sensors are both off in this order, and the time to shift to each on / off switching is within a predetermined time. Otherwise, it is an error. This is done in order to prevent the fraud in which the medal is reciprocated near the inserted medal detection sensor 75a and misidentified as the medal insertion, in addition to the medal clogging in the storage passage 81.

  Further, a power failure monitoring circuit 161 b provided in the power supply device 161 is connected to the input side of the main control device 131 via the input / output port 155. On the power supply substrate 161, a power supply unit 161a for supplying drive power to the main controller 131 and each electronic device of the slot machine 10, the above-mentioned power failure monitoring circuit 161b, and the like are mounted.

  The power failure monitoring circuit 161b monitors the power-off state and generates a power failure signal at the time of power-off by the power switch 122 as well as at the time of power-off. Therefore, the power failure monitoring circuit 161b monitors the stabilized drive voltage of DC 12 volts in this example output from the power supply unit 161a, and determines that the power is shut off when the drive voltage decreases to, for example, less than 10 volts. And a power failure signal is output. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes the power failure signal to execute power failure processing described later.

  Even when the output voltage drops below 22 volts, the power supply unit 161a is configured to output a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 131. As the time during which the stabilization voltage is output, a time sufficient to execute the process at the time of a power failure by the main control device 131 is secured.

  On the output side of the main control unit 131, each of the valid line display sections 32, 33, 34, the remaining number display section 35, the number-of-games display section 36, the obtained number display section 37, and the respective reels 42L, 42M, 42R are rotated. External stepping plate 61 capable of transmitting information to each stepping motor 61 (61L, 61M, 61R), medal passage switching solenoid 83 provided in selector 84, hopper device 91, display control device 111, hole management device not shown, etc. Etc. are connected via the input / output port 155.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU, a ROM, a RAM, and the like for driving them are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently controls driving of the upper lamp 13, the speaker 14 and the auxiliary display unit 15. Therefore, the display control device 111 is a sub-base that executes auxiliary control in relation to the main control device 131 which is the main base that centrally manages the game. That is, by providing sub-bases for sounds, lamps, and displays regarding indirect game play, the burden on the main base is reduced. The display control device 111 may control the various display units 32-37.

  In the CPU 151 described above, a ROM 152 storing various control programs to be executed by the CPU 151 and fixed value data, and an operation of temporarily storing various data in executing the control program stored in the ROM 152 Aside from the RAM 153 for securing an area, although not shown, as well known, various processing circuits necessary in the slot machine 10 such as timer circuits and data transmission / reception circuits including an interrupt circuit as well known, a credit counter for counting the number of credits Etc. are built in. The ROM 152 and the RAM 153 constitute a main memory as storage means, and programs for executing the processes shown in the various flowcharts shown in FIG. 25 and later are stored in the ROM 152 as a part of the control program.

  The RAM 153 is configured to be able to receive (back up) data by being supplied with a backup voltage from the power supply device 161 provided in the power supply box 121 even after the power supply of the slot machine 10 is shut off. In addition to a memory and an area for temporarily storing various data, etc., a backup area is provided.

  In the backup area, when the power is shut off due to the occurrence of a power outage, etc., the value of the stack pointer at the time of power shutoff (including the power shutoff by the operation of the power switch 122. The same applies to the following) This is an area for storing and when the power failure is canceled (including the power-on by the operation of the power switch 122. The same applies to the following), the state of the slot machine 10 before the power-off is based on the information of the backup area. It is possible to return to the state. The writing to the backup area is executed when the power is shut off by the power failure process (see FIG. 27), and the restoration of each value written to the backup area is executed in the main process (see FIG. 28) when the power is turned on. A power failure signal from the power failure monitoring circuit 161b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 151 at the time of power failure due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  Subsequently, each control process executed by the CPU 151 in the main control device 131 will be described with reference to the flowcharts of FIGS. The processing of the CPU 151 is roughly divided into main processing activated upon power-on, timer interrupt processing activated periodically (with 1.49 msec cycle in this embodiment), and NMI terminal (non-maskable terminal). In the NMI interrupt process activated by the input of the power failure signal, for convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 25 is a flowchart showing an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161 b of the power supply device 161 generates a power failure signal and outputs it to the main control device 131. The main controller 131 that has received the power failure signal via the NMI terminal executes NMI interrupt processing.

  In the NMI interrupt process, first, at step S101, data of a use register provided in the CPU 151 is saved in a backup area provided in the RAM 153. Subsequently, in step S102, a power failure flag is set in the power failure flag storage area provided in the RAM 153. Thereafter, the data saved in the backup area of the RAM 153 in step S103 is restored to the use register of the CPU 151 again. The NMI interrupt processing ends with this return processing. When the power failure flag can be set without destroying the data of the usage register of the CPU 151, the save and return processing to the backup area can be omitted.

  FIG. 26 is a flowchart of the timer interrupt process periodically executed by the main controller 131. The CPU 151 of the main controller 131 generates a timer interrupt every 1.49 msec, for example.

  First, in the register save process shown in step S201, the values of all the registers in the CPU 151 used in the normal process described later are saved in the backup area of the RAM 153. In step S202, it is confirmed whether or not the power failure flag is set. If the power failure flag is set, the process proceeds to step S203 to execute power failure processing.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register save process in the timer interrupt process, it can be performed without interrupting the other interrupt processes. Therefore, for example, during transmission processing of various commands, during reading processing of the state of the switch (on / off), etc., the processing upon power failure is not executed by interrupting each processing, and is executed at such timing. There is no need to create a program for power failure processing that also takes into account. As a result, the processing program for power failure processing can be simplified and the program capacity can be reduced. The same applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command transmission has ended. If the transmission has not ended, the process returns to the original process of FIG. As described above, it is determined whether the command transmission is completed at the initial stage of the power failure process, and if the transmission is not completed, priority is given to the transmission process, and the power failure process is executed after the unit command transmission process is completed. By doing this, it is not necessary to construct a power failure processing program which also takes into consideration that power failure processing is to be executed during command transmission. As a result, there is a benefit that the processing program for power failure can be simplified and the capacity of the ROM 152 can be reduced.

  If YES in step S301, that is, if the transmission of the command is completed, the process proceeds to step S302, and the value of the stack pointer of the CPU 151 is stored in the backup area in the RAM 153. Thereafter, in step S303, a RAM determination value, which will be described later, is cleared as stop processing, and the output state of the output port at the input / output port 155 is cleared to turn off all actuators not shown. In step S304, a RAM determination value is calculated and stored in the backup area. Specifically, the RAM determination value is the 2's complement of the checksum value at the work area address of the RAM 153. By storing the RAM determination value in the backup area, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, the subsequent RAM access is prohibited in step S305. After that, it enters an infinite loop in preparation for completely shutting down the power supply and making processing impossible.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilized voltage (5 volts) used as the drive voltage of the control system for a sufficient time to execute the above-described NMI interrupt process and power failure process. Are configured to In the present embodiment, the drive voltage is continuously output for 30 msec.

  Returning to the description of the timer interrupt process, when the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, the watchdog timer clear processing is performed to initialize the value of the watchdog timer for monitoring the occurrence of a malfunction. In step S205, interrupt termination declaration processing for issuing an interrupt permission to the CPU 151 itself is performed. In step S206, in order to rotate each of the reels 42L, 42M, 42R, a stepping motor control process of driving the stepping motors 61L to 61R, which are the respective spinning drum drive motors, is performed. In step S207, a sensor monitoring process is performed to monitor the states of various sensors (see FIG. 24) connected to the input / output port 155. In step S208, timer operation processing is performed to reduce the values of the counters and timers. In step S209, a counter process is performed to count the bet number of medals and the number of payouts.

  In step S210, command output processing for transmitting a command or the like to the display control device 111 is performed. In step S211, a segment data setting process is performed to set segment data to be displayed on each of the remaining number display unit 35, the game number display unit 36, and the acquired number display unit 37. In step S212, the segment data set in the segment data setting process is supplied to each of the display units 35 to 37 to perform segment data display process for displaying the corresponding numbers, symbols, and the like. In step S213, port output processing is performed to output data corresponding to the I / O device from the input / output port 155. In step S214, the value of each register saved in the backup area in the previous step S201 is restored to the corresponding register in the CPU 151, respectively. Thereafter, in step S215, an interrupt permitting process for permitting the next timer interrupt is performed, and the series of timer interrupt processes are ended.

  FIG. 28 is a flow chart showing main processing in the main control unit 131 which is executed after the power is turned on. The main process is performed when power is turned on by recovery from a power failure or the on operation of the power switch 122.

  First, in step S401, as initialization processing, the value of the stack pointer is set in the CPU 151, and an interrupt mode for permitting interrupt processing is set, and then various settings for the registers in the CPU 151, I / O devices, etc. Etc.

  When these initialization processes are completed, it is next determined in step S402 whether the reset switch 123 is turned on. If the reset switch 123 is turned on, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as the RAM clearing process.

  After confirming that the reset switch has not been operated in step S402, or after performing the RAM clear process in step S403, it is determined in step S404 whether or not the setting key is inserted into the setting key insertion hole 124. Do. If the setting key is inserted, the process proceeds to step S405 to perform setting change processing. As the setting change process, first, all data stored in the RAM 153 is cleared. Then, after determining which setting state is selected out of six preset setting states (“setting 1” to “setting 6”), internal processing according to the selected setting state is executed. .

  In step S406, it is checked whether the power failure flag is set. If the power failure flag is not set, that is, if the data in the RAM 153 is cleared in the previous step S403 or step S405, the process proceeds to a normal process of step S407 described later, and the present process is ended.

  If it is determined in step S406 that the power failure flag is set, the process proceeds to the power recovery process shown in step S408 and subsequent steps. The fact that the power failure flag is set means that the subroutine processing such as the RAM clear processing of step S403 and the setting change processing of step S405 is not executed at all. Therefore, the data in the RAM 153 is not rewritten at all, and in the power recovery process, it is necessary to confirm whether the data in the RAM 153 or the like is normal.

  For this purpose, first, in step S408, it is checked whether the RAM determination value is normal. Specifically, the checksum of the RAM 153 is checked, and it is checked whether the value is normal, that is, whether the checksum added with the RAM determination value is 0 or not. If the value of the checksum added with the RAM determination value is 0, it is determined that the data in the RAM 153 is normal.

  If the RAM determination value is abnormal at step S408, that is, the checksum value is not 0, there is a high possibility that the data in the RAM 153 is destroyed. Therefore, in such a case, error display processing is performed in step S409. As an error display process, the interrupt process is first inhibited, and all the output ports in the input / output port 155 are cleared to control all the actuators connected to the input / output port 155 in the off state. Thereafter, an error display is provided to notify the hole manager or the like of the occurrence of an error, and this state is maintained until the reset switch 123 is turned on.

  If it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S410, the value of the stack pointer stored in the backup area is written to the stack pointer of the CPU 151, and the state of the stack is cut before the power is shut off. Return to the state. Next, in step S411, a power recovery command for notifying the execution of the power recovery processing is transmitted to the display control device 111. Thereafter, in step S412, the game state is hit down and the automatic settlement setting save process is performed, and in step S413, various sensors such as the start detection sensor 71a are initialized. After the above process is completed, the power failure flag is reset in step S414, and the process returns to the address before the power was turned off. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S204) is executed.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S501, it is determined whether a medal has been betted. If a medal has been betted, it is then determined in step S502 whether the start lever 71 has been operated. If both step S501 and step S502 are YES, the lottery process of step S503, the reel control process of step S504, the medal payout process of step S505, and the special gaming state process of step S506 are sequentially executed, and the process returns to step S501. On the other hand, when the medal is not bet at step S501 or when the start lever 71 is not operated at step S502, the process returns to step S501.

  Next, the lottery process of step S503 will be described based on the flowchart of FIG.

  In step S601, based on the current setting state of the slot machine 10, the number of betted medals, the high / low probability of the small winning combination probability, and the like, a random number table for determination of success or failure is selected. Here, the setting state of the slot machine 10 is any of “setting 1” to “setting 6” set using a setting key (not shown), and the random number with the lowest winning probability of the winning combination in the case of “setting 1”. A table is selected, and when "setting 6", a random number table having the highest winning probability of combination is selected. Further, the number of medals betted is any one of 1 to 3, and a random number table is selected such that the winning probability of the winning combination becomes higher as the bet number is larger. For example, the winning probability of the winning combination when 3 bets are higher than three times the winning probability of the winning combination when 1 bet is made. Further, there are two types of small part probability, high and low, and when the current payout rate is below a predetermined expected value, a random number table with a high probability of winning a small part is selected, and when it exceeds a predetermined expected value A random number table with a low winning probability is selected.

  In step S602, the random number table thus selected is illuminated with the random number latched by the random number counter when the start lever 71 is operated, and a lottery for a winning combination is performed. Then, in step S603, it is determined whether or not one of the winning combinations has been won, and if the winning combination has not been won, the present process is terminated. If one of the winning combinations is won, the process advances to step S604 to set a winning flag according to the winning combination and to determine an effective line for aligning the symbols. Subsequently, in step S605, a slip table for controlling the reel stoppage is determined, and this is stored in the slip table storage area of the RAM 153. Here, if the symbol on the predetermined effective line at the timing when the stop switches 72 to 74 are pressed is different from the symbol to be stopped on the effective line, the slip table is the predetermined symbol to be stopped. It is a table that defines how much to slide the reel so as to stop on the effective line of.

  Next, the reel control process of step S504 will be described based on the flowchart of FIG.

  In the reel control process, first, a weight process is performed in step S701. This weight processing is processing for waiting without starting the rotation of the reel in the current game until a predetermined time (for example, 4.1 seconds) elapses from the start of the rotation of the reel in the previous game. Therefore, even if the player bets medals and operates the start lever 71, the reels 42L, 42M, 42R may not rotate immediately. Following the weight processing, the reel rotation processing of step S702 is performed to rotate each of the reels 42L, 42M, 42R. Thereafter, the process proceeds to step S703, and it is determined whether or not one of the stop switches 72 to 74 is pressed to generate a reel stop command. If the stop command has not been issued, the process proceeds to step S704, and it is determined whether a predetermined maximum rotation time (for example, 40 seconds) of the reels 42L, 42M, 42R has elapsed. If the maximum rotation time has not elapsed, the process returns to step S703, and if the maximum rotation time has elapsed, the process proceeds to step S705, and a forced stop process is performed to forcibly stop all reels in rotation.

  On the other hand, when one of the stop switches 72 to 74 is pressed in step S703 and a stop command is generated, the process proceeds to step S706, and reel stop processing is performed. In this reel stop process, the reel corresponding to the pressed stop switch is stopped, but it is won in the lottery of the role, and if the winning flag is set, it is stored in the slip table storage area of the RAM 153 By referring to the slip table, it is controlled so that the winning combinations are arranged on the predetermined effective line as much as possible. For example, when the stop switch is pressed at the timing when the "watermelon" symbol stops on the upper line, the symbol 2 is stopped to stop on the lower line. Slide the reels by one. However, since the range which can be slid is predetermined (for example, four symbols at maximum), the "watermelon" symbol may not stop on the lower line depending on the timing when the stop switch is pressed. Also in the forced stop process of step S705, when the winning flag is set, the same process is performed.

  Subsequently, in step S707, it is determined whether or not the current stop command is the first stop command, that is, whether or not the stop switch has been pressed while all three reels are rotating. In the case of the first stop command, the process proceeds to step S708, and slip table change processing is performed. In this slip table change process, for example, it is determined whether combination of the combination occurs when trying to align the combination on the winning line which has won, and when combination of the combination does not occur, it proceeds to the next step as it is, When a combination of winning combination occurs, the winning line is changed to another valid line, and the slip line table is changed to match the new valid line, and then the process proceeds to the next step. Here, in the combination of the roles, for example, when trying to align the "watermelon" pattern on the upper line, a plurality of roles occur simultaneously as in the case where the "cherry" pattern appears on the lower line on the left reel Say the case. The slip table changing process may be performed other than when avoiding combination of roles.

  On the other hand, when it is determined in step S707 that the current stop command is not the first stop command, the process proceeds to step S709, and whether or not it is the second stop command, that is, one of three reels is stopped and two reels are rotated. At this time, it is determined whether or not the stop switch has been pressed. When it is the second stop command, the process proceeds to step S710, and the stop determination processing is performed. In this stop point determination processing, when two reels stop, it is determined whether or not the two are aligned with the bonus symbol such as “7” symbol, and if not aligned, the process proceeds to the next step as it is and is aligned. When there is an effect sound or the like from the speaker 14, the process proceeds to the next step. In the stop eye determination process, it may be determined whether or not another condition other than two bonus symbols are aligned, or effects may be performed using the auxiliary display unit 15 in addition to the sound effect.

  Then, after the forced stop process of step S705, after the slip table change process of step S708, when the current stop command is not the second stop command in step S709, or the stop point determination process of step S710 is performed. Thereafter, in step S711, it is determined whether or not all rotations of the left, middle and right reels 42L, 42M, 42R have stopped. If step S711 is NO, the process returns to step S703, and if YES, the payout determination process is performed in step S712, and the process ends. In the payout determination process, it is determined whether or not the winning combination is aligned on the active line, and when the winning combination is not aligned on the active line, 0 is set in the expected payout number storage area of the RAM 153, and the winning combinations are aligned on the active line. If yes, it is determined whether or not the combination matches the winning combination, and if it does not match, an error is displayed by the upper lamp 13 or the like, and 0 is set in the expected payout storage area. If they match, the winning combination and the number of payouts corresponding to it are set.

  Next, the medal payout process of step S505 will be described based on the flowchart of FIG.

  In the medal payout process, first, it is determined whether or not the number of payouts counted by the number-of-payouts counter in step S801 matches the planned number of payouts stored in the planned number of payouts storage area. If the number of payouts and the scheduled number of payouts do not match, it is determined in step S802 whether or not a game is being performed in the credit mode. If it is in the credit mode, it is determined in step S803 whether the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit has not been reached, the count value of the credit counter and the number of payouts are incremented by one in step S804. As a result, the numbers of the remaining number display unit 35 and the obtained number display unit 37 are respectively incremented by one.

  On the other hand, when the game is being performed in the direct mode, or when the count value of the credit counter has reached the upper limit, the medal payout rotary plate is driven in step S805 to discharge medals from the hopper device 91 to the medal discharge port. Pay out to the medal receiver 18 through 17. At this time, in step S806, the number of payouts is incremented by one in accordance with the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. As a result, the number of acquired number display unit 37 is incremented by one. Then, after incrementing the number of payouts by one in step S804 or step S806, the process returns to step S801 again. If it is determined in step S801 that the number of payouts agrees with the number of payouts, the medal payout rotary plate of the hopper device 91 is stopped in step S807, and the process ends. The number of payouts and the number-of-earnings display unit 37 are reset when the start lever 71 is operated next time.

  Next, the special gaming state process of step S506 will be described based on the flowchart of FIG.

  Prior to the description of the special game state process, the bonus game will be described. The regular bonus (hereinafter referred to as "RB") game is composed of 12 JAC games. The JAC game is a game in which only one bet is permitted, and is a game in which the probability that the JAC symbol (in this case, a replay symbol) is aligned on the effective line, that is, the probability of the JAC symbol being established is very high. When the JAC symbol is established in the JAC game, the maximum number (15 in this case) of medals is paid out. Then, when the JAC symbol is established eight times, the RB game is ended even before the JAC game reaches twelve times. On the other hand, the big bonus (hereinafter referred to as "BB") game is composed of 30 small role games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability (a “bell” symbol etc. is aligned on the active line), and a JAC in means to enter 12 JAC games, a small role game When the JAC pattern is aligned on the effective line, JAC in is established. The JAC game is similar to the RB game. Also, when the third JAC-in JAC game ends, the BB game ends even before the small-combination game reaches 30 times, and when the 30 small-combination games end, before the JAC-in reaches three times Even if there is a BB game is over.

  In the special game state process, first, at step S901, it is determined whether or not the game state is a bonus game. If the bonus game is not in progress, the process proceeds to step S902, and a bonus symbol determination process is performed.

  In this bonus symbol determination process, as shown in FIG. 34, it is first determined whether or not the RB win flag is set in step S1001. If it is set, the process proceeds to step S1002, and the RB symbol on the current effective line is determined. It is determined whether or not (for example, "BAR" symbol) is aligned, and when the RB symbol is not aligned, the present process is ended as it is. On the other hand, when the RB symbol is aligned on the effective line this time, the RB winning flag is reset in step S1003 and the RB setting flag is set to set it as an RB game which is one kind of bonus game. RB game initial setting processing shown in FIG. To finish this process. If it is determined in step S1001 that the RB winning flag is not set, it is determined in step S1004 whether the BB winning flag is set. If not, the present process ends. If the BB winning flag is set, the process proceeds to step S1005, and it is determined whether or not the BB symbol (for example, symbol "7") is aligned on the active line this time. . On the other hand, when the BB symbol is aligned on the effective line this time, the BB winning flag is reset in step S1006 and the BB setting flag is set to set a BB game as one type of bonus game, and the BB game initial setting processing shown in FIG. Execute and complete this process.

  In FIGS. 35 and 36, the remaining small combination game counter represents the number of remaining small combination games (also referred to as the number of remaining small combination games), and the remaining JAC in counter indicates the number of remaining JAC in possible times (the remaining JAC in times). The remaining JAC formation counter represents the number of times the JAC symbol can be established (also referred to as the remaining JAC formation number), and the remaining JAC game counter represents the number of remaining JAC games (also referred to as the remaining JAC game number). Represent. The number of remaining small winning combination games, the number of remaining JAC ins, the number of remaining JACs established, and the number of remaining JAC games are appropriately displayed on the number-of-games display section 36. By the way, when the small winning combination or the replay winning flag is set by winning the small winning combination or the replay in the lottery of the winning combination, these winning flags will not be aligned on the effective line of the small winning combination symbol or the replay symbol in the game. Is reset, but when the RB or BB winning flag is set by winning RB or BB in the lottery for the role, even if the RB symbol or BB symbol is not aligned on the effective line in the game The winning flag of will be carried over to the next time. In the lottery process in the next game carrying over the BB or RB winning flag, a lottery regarding whether or not a small winning combination or replay is won is performed, but a lottery regarding BB or RB is not performed. Further, when the small winning combination or the replay is won with the BB or RB winning flag carried over, the slip table is stored so that the small winning combination or the replay is preferentially arranged.

  Referring back to FIG. 33, when the gaming state is the bonus game in step S901, it is determined in step S903 whether the bonus game is a JAC game. If it is not a JAC game, it means that a small winning combination game of the BB game is being played, so the processing proceeds to step S904, and it is determined whether or not the JAC symbol is aligned on the effective line. When the JAC symbol is aligned on the effective line, the JAC game is started in step S905, and the JAC game initial setting process in the BB game of FIG. 36 (b) is performed, and this process is ended. On the other hand, when the JAC symbols are not aligned on the effective line in step S904, the small combination game is one game, so the number of remaining small combination games is decremented by 1 in step S906, and in step S907. It is determined whether the number of remaining small winning combination games has become 0 or not. If the number of remaining small winning combination games is not zero, the processing is terminated. If it is zero, the processing proceeds to step S908, where special processing state ending processing is performed to appropriately reset various setting flags, BB setting flags, various counters, etc. To complete this process.

  If it is determined in step S903 that the gaming state is a JAC game, the process proceeds to step S909 to determine whether the JAC symbol is aligned on the activated line, and when the JAC symbol is aligned on the activated line, the remaining JAC formation count is determined in step S910. 1 Decrement. Thereafter, or if the JAC symbols are not aligned on the effective line in step S909, it means that one JAC game has been consumed, so the number of remaining JAC games is decremented in step S911. Subsequently, in step S912, it is determined whether or not either the remaining JAC formation number or the remaining JAC game number has become 0, and when none has become 0, that is, the JAC symbol has not yet been established 8 times. If the JAC game has not been digested 12 times, this processing ends. On the other hand, when one of the JAC symbols has been established 8 times, or when the JAC game has been digested 12 times, since the JAC in has been digested once, the remaining JAC in has been dropped in step S913. The number is decremented by one, and it is determined in the following step S914 whether the remaining JAC-in count is zero. When it is 0, the special game state end process of step S908 described above is performed, and this process is ended. Incidentally, if the bonus game is an RB bonus, the initial remaining number of JAC ins is 1 (see FIG. 35), so it becomes 0 in step S913 and a positive determination is always made in step S914 and the special game of step S908. The RB setting flag is reset in the state end process.

  On the other hand, when the remaining JAC-in count is not zero in step S914, that is, when the JAC-in has not been consumed three times in the BB game, after performing the JAC game end processing of resetting the JAC game setting flag in step S915, the current JAC Since the small role game is consumed by one when the game is in, the number of remaining small portion games is decremented by 1 in step S906, and then it is determined in step S907 whether the number of remaining small portion games has become 0 or not. If it is determined that the number of remaining small winning combination games is 0, the special game state end processing of step S908 described above is performed, and the present processing is ended. On the other hand, when the number of remaining small winning combination games is not 0, the present processing is ended because the small winning combination games in the BB bonus have not reached 30 times and the JAC in has not reached 3 times.

  According to the present embodiment described above, the following excellent effects can be obtained.

  In the first sealing portion of the main controller 131, the sealing pin member 321 used at the time of sealing has the elastically deformable locking claw portion 321c, and the insertion side coupling portion cut out from the front case body 271 at the time of sealing release. It was set as the structure which will be in a locked state with respect to 291. In this case, by elastically deforming the locking claw portion 321c, the sealing pin member 321 can be removed from the insertion side coupling portion 291 in the same state as that before the sealing processing without any breakage or the like, and this sealing pin member It becomes possible to use 321 for the sealing process in another sealing joint part. Therefore, it is not necessary to prepare a spare sealing pin member 321 and to secure its storage space. As described above, the sealing structure of the substrate box can be improved, and the configuration can be simplified.

  Since identification information for each slot machine 10 is given to the sealing pin member 321, in the case where sealing processing is performed using the sealing pin member 321 used in another slot machine, misalignment of the identification information occurs. Therefore, it is possible to confirm that the sealing process has not been performed properly.

  Similarly, in the first sealing portion of main controller 131, the easily breakable portion (connection portion 292) is provided only in the sealing joint portion (insertion side joint portion 291) on the front case body 271 side, and the sealing pin member 321 is Only the sealing joint (insertion side joint 291) on the front case body 271 side is engaged. Therefore, the breaking process on the side of the pedestal device 210 is not performed at the time of sealing removal. That is, even if the sealing process and the releasing process are performed, the pedestal device 210 can be maintained in the same state. Thus, the pedestal device 210 can be reused, and the reuse can be promoted. For example, when changing the model of the slot machine 10, reuse of the base device 210 together with the housing 11, the front door 12 and the like greatly promotes reuse of parts.

  For example, even if the main control device 131 is tampered with so much that it can not be restored as it was, it can be dealt with by replacing only the main control device 131 leaving the base device 210. In this case, by replacing the main control device 131 with a new one, all the first sealing portions can be updated to the sealing state before the fraud.

  In the main board unit 200 attached to the back plate 11 c of the housing 11, the movable base plate 212 on which the main controller 131 is mounted can be pivoted with respect to the fixed base plate 211, so the main controller 131 is pulled toward the front side It becomes possible. Therefore, when an employee, manager or the like of the game hall checks the main control device 131, the checking operation can be performed in a state where the control device 131 is drawn to the near side. At this time, when the movable base plate 212 pivots, the back surface (main substrate back surface) of the main controller 131 is opened, so check on the back surface side whether there are any abnormalities or irregularities in various electronic components, electrical wiring, etc. It can be carried out. As a result, it is possible to confirm that the main control apparatus 131 has not performed an unauthorized action, and in turn, the main control apparatus 131 can be properly managed.

  Further, as described above, the movable base plate 212 on which the main controller 131 is mounted is configured to be rotatable with respect to the fixed base plate 211, and the sealing portion (first sealing portion) of the substrate box Since it is provided on the side, the sealing portion of the substrate box can not be attracted even when the main controller 131 is attracted. Therefore, it becomes difficult to unseal the substrate box illegally, and the deterrence against fraud is enhanced.

  Since the first sealing portion is installed on the front surface portion of the substrate box viewed from the front opening portion of the housing 11, the first sealing portion is configured to rotate the main controller 131 together with the movable base plate 212. The installation place of can be secured easily. At this time, the effect that the movable base plate 212 is not easily disturbed can also be obtained. Further, on the surface side of the main control device 131, there is no other member that prevents visual confirmation of the main control device 131, so that the side of the substrate box (for example, the upper side or the lower side of the box in FIG. It is thought that confirmation of the said sealing part becomes easier than the case where the 1st sealing part is provided in the side).

  Since the pedestal device 210 is fixed to the back plate 11 c of the housing 11 so that the first sealing portion is disposed on the same side as the opening / closing axis of the front door 12, the first sealing portion is not opened unless the front door 12 is largely opened. It becomes difficult to unseal the seal. Therefore, the deterrent against the unfair seal removal act can be heightened.

  As an effect of attaching the main board unit 200 to the back plate 11 c of the inner peripheral surface of the housing 11, the main controller 131 is difficult to be removed improperly, and the main controller 131 is attached while the main controller 131 is attached. It is difficult to perform unauthorized work on the object, and since the distance between the main control unit 131 and the front opening of the housing 11 becomes long, an incorrect signal line is connected to the main control 131 via the front opening of the housing 11 It is difficult to cheat, when the front door 12 is opened, the main controller 131 is seen in the front, so it is easy to find irregularities on the surface of the board. If you do not insert your hands to the back of the case 11, the seal seal S can not be peeled off. Since the width dimension is larger than 11d and 11e, effects such as being able to mount even a relatively large controller can be obtained.

  The main control unit 131 is configured to be detachable from the turning end portion side of the movable base plate 212 by sliding the main control unit 131 on the movable base plate 212 while the movable base plate 212 is turned. As a result, the main control unit 131 can be easily attached or detached in a state in which the pivoting tip of the movable base plate 212 is drawn to the front side. Therefore, the workability at the time of inspection or replacement of the main control device 131 can be improved.

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

  (A) In the above embodiment, the main board unit 200 is attached to the back plate 11c of the housing 11. However, instead of this, the main board unit 200 is used as either the left or right side plate 11d or 11e of the housing 11. It is good also as composition attached to. Even if it is attached to either the left or right side plate 11 d or 11 e of the housing 11, the main control unit 131 can be turned to the near side by making the turning base plate 112 rotatable with respect to the fixed base plate 211. 10) can be drawn forward, and the above-mentioned excellent effects can be obtained.

  (B) In the above embodiment, in the main board unit 200, the fixed base plate 211 and the movable base plate 212 have substantially the same size according to the main controller 131 (substrate box), but this configuration is changed. For example, the movable base plate 212 is smaller than the main controller 131 (substrate box). Specifically, a configuration is conceivable in which the length in the longitudinal direction of the movable base plate 212 is set to 2/3, 1⁄2, or 1⁄3 of the length of the main control device 131. Alternatively, the bottom plate portion 241 of the movable base plate 212 may be partially cut out including the central portion, or the bottom plate portion 241 may be provided with a see-through window. In any case, the movable base plate 212 may be configured to be turned so that the back surface of the main control device 131 can be easily confirmed. The fixed base plate 211 may also be smaller or larger than the main control unit 131 on the premise that the main control unit 131 can be securely mounted.

  (C) In the above embodiment, the shaft support is provided at the short side of the fixed base plate 211. However, the shaft support may be provided at the long side of the fixed base plate 211. In this case, although the amount of pull-in to the front side of the movable base plate 212 is reduced, it is the same that the facing angle of the main controller 131 when viewed from the front of the slot machine changes. It can be implemented.

  (D) In the above embodiment, although the fixed base plate 211 and the movable base plate 212 constituting the pedestal member 210 are both formed of a transparent synthetic resin material, the fixed base plate 211 is a colored resin material. The fixed base plate 211 may be formed of metal or the like other than the resin material. In addition, the movable base plate 212 only needs to be able to visually recognize the back surface of the main controller 131. For example, if a configuration such as providing a visible window on the bottom plate portion 241 of the movable base plate 212 is added, it can be changed to a colored resin material Other than the resin material, for example, the material may be changed to metal or the like.

  (E) An illumination means such as a lamp is provided in the inside of the housing 11, and the lamp etc. (illumination means) is turned on when the movable base plate 212 is rotated with respect to the fixed base plate 211. As a result, it is possible to easily confirm the presence or absence of an unauthorized action on the main control device 131 or the pedestal device 210. The illumination means may be attached to the housing 11 or attached to the pedestal device 210.

  (F) In the above embodiment, the first sealing portion of the main substrate unit 200 is provided on the surface side of the front case body 271, but instead, the side portion of the front case body 271 (for example, the upper side of the case in FIG. Or you may provide in lower side. However, in this case, it is desirable that no other member is disposed to prevent the first sealing portion from being visually recognized. In any case, it is preferable to provide such a sealing portion on the pivot shaft side of the pedestal device 210 in order to enhance the deterrence against fraud.

  (G) In the above embodiment, in the first sealing portion of the main substrate unit 200, the insertion side coupling portion 291 is juxtaposed in four in the front case body 271, and the receiving side coupling portion 251 is made correspondingly. Although four movable base plates 212 are arranged in parallel, this configuration is changed. At least one of the four receiving couplings is provided in the back case body 272. Even with this configuration, it is possible to realize an appropriate sealing structure. Also, instead of the sealing performed by the front case body 271 and the movable base plate 212, the sealing performed by the back case body 272 and the movable base plate 212 or the sealing performed by the front and back case bodies 271 and 272 It is also possible.

  (H) The configuration of the second and third sealing units of the main control device 131 can be modified to others. Also in the places where the sealing portions are provided, in addition to the left and right short sides of the substrate box (cases 271 and 272), they may be provided on the long side of the substrate box (cases 271 and 272). Moreover, it may replace with the structure which uses a sealing screw and may be the structure etc. which insert a sealing metal fitting piece in a sealing connection part. At least a first sealing unit may be provided as the sealing unit, and the other sealing units (a second sealing unit, a third sealing unit) may be omitted.

  (I) In the above embodiment, in the main substrate unit 200, the movable base plate 212 is rotatably provided with respect to the fixed base plate 211. However, the pedestal device 210 may be configured not to have a pivoting function. . In this case, the pedestal device 210 simply mounts the main control device 131 detachably.

  (J) It is also possible to use a reusable sealing pin member (insertion member) as a sealing means provided between the front and back pair of case bodies 271 and 272. That is, the pedestal device is not a requirement. Also in this case, it is not necessary to prepare a spare sealing pin member and to secure its accommodation space. As described above, the sealing structure of the substrate box can be improved, and the configuration can be simplified. In such a case, to briefly describe the additional configuration of the substrate box, it is possible to open both case bodies by sliding the other case body along the case face of one case body, A communicating hole portion of the coupling portion (sealing portion) is formed to extend in a direction orthogonal to the sliding direction. Further, the easily breakable portion is provided only in the combined body of one of the case bodies, and the insertion member can be locked only to the combined body in which the easily breakable portion is provided.

  (K) In the above embodiment, the main controller 131 including the main board 273 is mounted on the pedestal device, but the same configuration may be provided to other control devices other than the main controller 131 .

  (L) The present invention can be applied to gaming machines other than the slot machine. For example, the present invention can be applied to a ball game machine such as a pachinko machine, an arrange ball machine, a game machine such as a ball, and a ball using belt type game machine using a game ball as a game medium.
