The distal end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and positioned so as to pass between the two elements 55a and 55b of the reel index sensor 55. Then, each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the tip end portion 56a of the sensor cut van 56, and a detection signal is output to the main control device 131 described later each time the detection is performed. Therefore, main controller 131 can confirm and correct the angular position of left reel 42L for each rotation based on this detection signal.

  The stepping motor 61L is set to be rotated once by giving a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter), and the rotation position of the stepping motor 61L, that is, the left The rotation 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 (circumferential direction). Therefore, it takes 24 pulses (= 504 pulses ÷ 21 symbols) to switch from one symbol at the predetermined position to the next symbol. Then, based on the number of pulses from the time when the detection signal of the reel index sensor 55 is output, it is possible to recognize which symbol is visible from the display window 31L, or to visually recognize an arbitrary symbol from the exposure window 31L. Can be controlled.

  Among the symbols attached to each of the reels 42L, 42M, 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, 31R is mainly determined by the vertical length of the display windows 31L, 31M, 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. Therefore, in a state where all the reels 42L, 42M, 42R are stopped, 3 × 3 = 9 symbols can be visually recognized by the player.

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

  As the symbols, there are a "7" symbol (for example, the twentieth left belt) and a "youth" symbol (for example, the nineteenth left belt) as the first special symbol for shifting to the big bonus game. In addition, there is a "BAR" symbol (for example, the 14th left belt) as a second special symbol for shifting to a regular bonus game. In addition, there is a “replay” symbol (for example, the eleventh left belt) as a third special symbol for shifting to a replay game. In addition, a “watermelon” symbol (for example, the ninth left belt), a “bell” symbol (for example, eighth belt), and a “cherry” symbol (for example, left Belt 4). As shown in FIG. 7, the number and arrangement order of various symbols are completely different in the belt wound around each of the reels 42L, 42M, 42R.

  The reels 42L, 42M, 42R of the reel unit 41 are examples of variable display means for variably displaying identification information, and constitute a main display unit. However, the variable display means may have another configuration. For example, other mechanical reel configurations, such as a type in which the belt rotates instead of rotating, may be used. Alternatively, instead of or in addition to the mechanical reel configuration, a liquid crystal display, a dot matrix display For example, a device for variably displaying the identification information by an electrical display such as the above may be provided. In this case, it is possible to provide a variety of display forms.

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. Corresponding to each of these combination lines, effective line display units 32, 33, 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, 31R group. When the center horizontal line (center line) of the combination lines is activated, the first activated line display unit 32 is informed by lighting or the like. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second activated line display unit 33 is informed by lighting or the like. When the pair of diagonal lines (lower right line and upper right line) out of the combination lines are activated, the third active line display unit 34 is informed by lighting or the like. Then, when the symbols are stopped in a predetermined combination on the activated combination line, that is, the activated line, a winning is achieved, 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 a winning is achieved will be described. With regard to the small role design, when the "watermelon" design is aligned with the left, center and right on the active line, 15 medals are paid out, and when the "bell" design is aligned with left, center and right on the active line. Pays out eight medals, and pays out two medals when the "cherry" symbol on the left reel 42L stops on the activated line. 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 only, medals are paid out irrespective of the combination with other symbols, and therefore, “ When the "cherry" symbol is stopped, medals are paid out by multiplying the number of overlapped effective lines, and as a result, in the present embodiment, four medals are paid out.

  As for other symbols, when the "7" symbol or "Youth" symbol, which is a combination of the first special symbol (big bonus symbol), is aligned with the left, center, and right on the activated line in the same symbol 15 medals are also paid out when the "BAR" symbol, which is a combination of 15 medals and the second special symbol (regular bonus symbol), is aligned with the left, center and right on the activated line. In the present embodiment, for example, a case may occur where the “7” symbol and the “cherry” symbol are simultaneously established. In such a case, fifteen medals are paid out. This is because the maximum number of coins in one medal payout is set to 15.

  Further, if the "replay" symbol, which is a combination of the third special symbols, is aligned with the left, center, and right on the activated line, no medal is paid out. In other cases, that is, when the "cherry" symbol of the left reel 42L does not stop on the activated line, and when the same symbols as the left, middle, and right are not aligned on the activated line, no medals are paid out.

  When the change-over switch 80 is in the ON state, the “credit mode” is set so that surplus inserted medals or medals obtained at the time of winning a prize until a predetermined maximum value (for example, 50 medals) are obtained are stored as credit medals. ". When the changeover switch 80 is in the off state, the "direct mode" is set in which surplus inserted medals and medals obtained at the time of winning are paid out as actual medals. When there is a credit medal when the mode is switched from the credit mode to the direct mode, the corresponding credit medal is paid out as an actual medal. As described above, the player can execute 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 changing over the handling mode of the input value and the game value. Focusing on the function of paying out the credited virtual medals as real medals, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the game value stored and stored. It should be noted that, in addition to a configuration in which the mode is switched between the "credit mode" and the "direct mode" by operating the changeover switch 80, the "credit mode" is always set, and when the changeover switch 80 is operated, the stored virtual medals are paid out. It may be made to function only as a balance switch.

(In the present embodiment, four) seal connecting portions 291 are provided so as to be arranged in a vertical line. FIG. 14 is an enlarged view of the peripheral configuration. The sealing connecting portion 291 has a cylindrical shape, and is connected to the front case body 271 by connecting portions 292 on both right and left sides. By cutting the connecting portion 292, the sealing connection portion 291 can be cut off from the front case body 271. Similarly, a plurality of (two in the present embodiment) sealing connection portions 293 constituting a second sealing portion are provided in the cutout square hole portion 290 so as to sandwich the plurality of sealing connection portions 291. The seal connecting 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 sealing connection portion 293 can be cut off 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 cutout square holes 290 formed in the front case body 271, they may protrude to the side of the board case. In contrast to the conventional general configuration in which a sealing portion is provided, there is no inconvenience such that the sealing connecting portions 291 and 293 protrude to the side to be in the way. Further, since the sealing connection portions 291 and 293 do not protrude to the side, there is no fear that the sealing connection portions 291 and 293 may be damaged by being hit 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 control device 131 is slidably mounted on the movable base plate 212. The leading end portion is provided with a locking claw 295 and a locking claw. A pair of screw holes 296 is provided so as to sandwich the portion 295. When the main controller 131 is mounted on the movable base plate 212, the locking claw 295 is locked in the locking hole 247 provided in the movable base plate 212. The screw holes 296 and the through holes 248 provided in the movable base plate 212 are aligned with each other, and small screws 297 are screwed into the through holes 248 and the screw holes 296 in this state.

  On the left side of the cutout square hole portion 290 of the front case body 271, an enclosing frame 332 that defines and forms a surface to which the sealing seal S is attached is formed. When the main control device 131 is mounted on the movable base plate 212, the surrounding frame 332 of the front case body 271 and the surrounding frame 331 formed on the movable base plate 212 are integrated with each other to form a rectangular frame-shaped enclosure as a whole. A frame is formed.

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

  Further, a key mounting bracket 305 is mounted and fixed to the right end of the front case body 271. The base 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 distal end of the key attachment 305 is bent obliquely 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, a plurality of hook portions 312 erected in the height direction of the substrate and formed with L-shaped tips are provided at predetermined intervals on both upper and lower sides of the bottom plate portion 311 in the figure. Have been. The hook portions 312 are provided at the same intervals as the elongated holes 286 of the front case body 271, and the two case bodies 271 and 272 are formed by the elongated holes 286 of the front case body 271 and the hook portions 312 of the back case body 272. Is to be assembled.

  FIG. 18 (an end view taken along the line BB in FIG. 8) shows an assembly 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 in this state, the hook portion 312 is formed in the long hole 286 of the front case body 271. Locked by locking portion 286a. Thereby, the front case body 271 is held without being lifted with respect to the back case body 272. FIG. 18 shows a state in which the main control device 131 is assembled to the pedestal device 210 and the front case body 271 cannot be slid in the lateral direction with respect to the back case body 272. Assuming that the front case body 271 is not assembled to the front case body 271, the front case body 271 is once slid to the right in FIG. 18 and then lifted upward to separate the front case body 271 from the back case body 272 (FIG. 18). The front case body 271 is moved along the arrow P inside).

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

  Returning to the description of FIG. 13 again, a pair of upper and lower extensions 314 a and 314 b is provided at the left end of the back case body 272 so as to extend leftward from the bottom plate 311. Each of the portions 314a and 314b is provided with a sealing connection portion 315 constituting a second sealing portion. The sealing joint 315 has a cylindrical shape whose bottom is closed by the same surface as the bottom plate 311, and is opened only on the near side in the drawing. The extension portions 314a and 314b are provided vertically separated from each other, and a space between the extension portions 314a and 314b is provided for avoiding interference with a plurality of sealing coupling portions 251 provided on the movable base plate 212. It is an empty space.

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

  At the right end of the back case body 272, a plurality of (two in the present embodiment) sealing coupling portions 317 constituting a third sealing portion are provided. The sealing connection part 317 is connected to the back case body 272 by a connection part 318. By cutting the connecting portion 318, the sealing connection portion 317 can be cut off 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 will be sequentially referred to as a first sealing portion, a second sealing portion, and a third sealing portion. FIG. 19 corresponds to an end view taken along line CC of FIG. 8, and shows a cross-sectional structure of the first sealing portion. FIG. 20 is an end view taken along line DD of FIG. 8 and shows a cross-sectional structure of the second sealing portion. FIG. 21 is an end view taken along the line EE of FIG. 8 and shows a cross-sectional structure of the third sealing portion.

  First, the configuration of the first sealing portion will be described with reference to FIG. In FIG. 19, (a) shows a state before sealing, (b) shows a sealed state, and (c) shows a state of unsealing. The first sealing portion can be in a sealed state by coupling the sealing coupling portion 291 provided on the front case body 271 and the sealing coupling portion 251 provided on the movable base plate 212. For convenience, the first sealing portion is referred to as “insert”. The description will be continued by rephrasing the "side coupling portion 291" and the latter as the "receiving coupling portion 251".

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

  Reference numerals 251c and 291c are semicircular return portions provided on the receiving side coupling portion 251 and the insertion side coupling portion 291 respectively (the return portion 251c is located forward of the main control device 131 in the sliding direction, 291c is provided behind the main controller 131 in the sliding direction), and the connecting portions 251 and 291 abut on the return portions 251c and 291c. The facing joint surfaces of the coupling portions 251 and 291 are hidden by the return portions 251c and 291c.

  At the time of performing the sealing process, as shown in FIG. 19B, each of the holes 291 a and 251 a of the insertion-side coupling portion 291 and the receiving-side coupling portion 251 has, for example, a substantially hollow cylindrical shape made of synthetic resin. 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-shaped head 321b, and two elastically deformable locking claws 321c provided at, for example, two locations on the cylindrical portion 321a. In the normal state, the locking claw portion 321c protrudes outward from the outer periphery of the cylindrical portion 321a, and the locking claw portion 321c can be immersed in the cylindrical portion 321a by applying an external force. I have. Identification information (for example, an identification code) for each main controller 131 is attached to the head 321b 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, and is inserted until the head portion 321b hits the step 291b at the upper hole entrance. 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 rises, and the rear end face of the locking claw portion 321c is connected to the insertion side. It is locked on the tip surface of the portion 291. Thereby, the sealing of the first sealing portion is completed, and the falling off of the sealing pin member 321 after the sealing is prevented.

  In order to release the sealing of the first sealing portion at the time of occurrence of a failure or inspection of the main control device 131, as shown in FIG. 19 (c), 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. At this time, only the distal end of the sealing pin member 321 is inserted into the receiving-side connecting portion 251, and since these members 251 and 321 are not in a locked state at all, the connecting portion 292 is inserted by cutting. The side connecting portion 291 and the sealing pin member 321 can be easily cut off from the front case body 271. The cut-out insertion-side coupling portion 291 and the sealing pin member 321 can be easily separated from each other by elastically deforming the locking claw portion 321c of the sealing pin member 321 by pressing it with a finger or a tool. The separated sealing pin member 321 is not accompanied by any deformation or destruction, and the same sealing pin member 321 is used for the next sealing.

  As described above, since the identification information for each main controller 131 is attached to the head 321b of the sealing pin member 321, after the sealing process is performed again by reusing the sealing pin member 321, the identification information is not changed. By confirming, it can be confirmed whether or not the sealing process has been performed according to the regular procedure.

  When the sealing of the first sealing portion is released, the portion to be cut (broken) is only the connecting portion 292 on the front case body 271 side, and the sealing counterpart, that is, in this case, the movable base plate 212 is not broken at all. 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 destroyed and the sealing history does not remain. Therefore, even when the main control device 131 is replaced, the movable base plate 212 (that is, the pedestal device 210) can be reused as it is.

  In the first sealing section, the order of which of the four sealing locations is used is determined in advance, and for example, sealing is performed one by one from the top in FIG. At the sealing location where the cutting process (destruction process) has been performed after the sealing, the sealing history remains, so that it is possible to easily confirm how many times the sealing process has been performed in the past.

  Next, the configuration of the second sealing section will be described with reference to FIG. The second sealing portion can be in a sealed state by connecting the sealing connection portion 293 provided on the front case body 271 and the sealing connection portion 315 provided on the back case body 272. The description proceeds by rephrasing the "side coupling portion 293" and the latter as the "receiving coupling portion 315".

  As shown in FIG. 20, a hole 293a (referred to as an upper hole for convenience) penetrating in the up-down direction is formed in the insertion-side coupling portion 293 of the front case body 271. The receiving side coupling portion 315 is formed with a hole 315a (for convenience, referred to as a lower hole) communicating with the upper hole 293a coaxially. The upper hole portion 293a is formed with a large-diameter portion for accommodating a head of a sealing screw 323 described later, and a small-diameter portion smaller than the large-diameter portion. A female screw portion is formed in the lower hole portion 315a. Then, the sealing screw 323 is screwed into each of the holes 293a and 315a of the insertion-side coupling portion 293 and the receiving-side coupling portion 315, whereby the sealing of the second sealing portion is completed. The sealing screw 323 is constituted by a so-called break screw having a break portion (reduced diameter portion) which is easily broken at an intermediate portion. When the screw 323 is screwed by a tightening tool such as a screwdriver, a predetermined torque or more is applied. Then, the breaking portion is broken. Due to this breakage, once the sealing screw 323 is screwed into the holes 293a and 315a, the screw 323 cannot be loosened thereafter.

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

  Next, the configuration of the third sealing portion will be described with reference to FIG. The third sealing portion can be brought into a sealed state by connecting the sealing connection portion 301 provided on the front case body 271 and the sealing connection portion 317 provided on the back case body 272. The description proceeds with the “side coupling portion 301” and the latter “the receiving coupling portion 317”.

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

  To release the sealing of the third sealing portion, a connecting portion 302 for connecting the insertion side connecting portion 301 and the front case body 271 and a connecting portion 318 for connecting the receiving side connecting portion 317 and the back case body 272 are provided. Are cut together using a tool such as a nipper (part X3 in the figure). Thereby, the sealing screw 325 can be separated from the case bodies 271 and 272, and the sealing of the third sealing portion can be released.

  In the above description, it is described that the sealing process is performed for both the second sealing portion and the third sealing portion. However, actually, only one of these sealing portions is subjected to the sealing process. For example, the second sealing portion is sealed when the main board 273 is accommodated in the board boxes (case bodies 271 and 272) in manufacturing the slot machine 10. Then, when the main control device 131 is recovered for inspection or the like, the second sealing portion is opened, and after the inspection or the like, the third sealing portion is sealed.

  On the other hand, as shown in FIG. 9 and the like, on the left side of the main substrate unit 200, the movable base plate 212 and the front surface of the front case body 271 are attached with a seal attaching surface surrounded by the surrounding frames 331 and 332. A rectangular seal S is attached so as to straddle the case body 271. The sealing seal S is such that if it is peeled off after being once adhered, the adhesive peels off from the seal label and cannot be re-applied. If the sealing seal S is peeled off, its trace remains. It can be checked whether the main controller 131 has been removed from the plate 212. In the illustrated state where the sealing seal S is attached, the locking hole 247 and the through hole 248 formed in the movable base plate 212 are covered and hidden.

  As described above, the seal S has a configuration that cannot be re-applied. However, there is an illegal act of attaching another seal member after the seal S is peeled off. It is considered that one measure is to suppress the act of removing the seal S. Therefore, in the present embodiment, as a measure against peeling of the seal, the seal attachment surface composed of the surface of the movable base plate 212 and the surface of the front case body 271 is surrounded by the surrounding frames 331 and 332, and the peripheral edge of the seal attachment surface is curved. It is formed in a shape. Specifically, the seal sticking surface is formed in a curved shape by forming a tapered surface in accordance with the long side of the sealing seal S.

  When the seal S is adhered to the seal affixing surface, the periphery of the seal S enters the curved portion of the seal affixing surface, and it becomes difficult to hook the periphery of the seal S with a nail or the like. Therefore, a deterrent effect against illegally peeling off the seal S is obtained.

  As shown in FIG. 22, when the main control device 131 is mounted on the pedestal device 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 device 131. Are facing each other, and a 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. Further, in a state where the fixed base plate 211 and the movable base plate 212 are superimposed, a key mounting bracket 219 provided on the fixed base plate 211 and a key mounting 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 fittings 219 and 305. The unlock keys of the key members K1 and K2 are managed by a game hall manager or the like.

  In such a configuration, the movable base plate 212 cannot be rotated with respect to the fixed base plate 211 unless the key member K2 is removed. Even if the key member K2 is removed, the main controller 131 cannot be removed from the movable base plate 212 unless the key member K1 is removed. Therefore, the main controller 131 cannot be removed unless the owner of the unlock key is properly managed.

  Each of the above-mentioned sealing portions is originally configured to be cut (breakable), and its main purpose is to leave an opening history, so that deterrence such as taking away (stealing) the main controller 131 is suppressed. Although the effect cannot be exerted, the above-described configuration in which the key members K1 and K2 are attached can exert an effect of deterring the removal of the main control device 131 (which can be a measure for preventing the main control device 131 from being stolen).

  The tips of the key attachments 219 and 305 are provided to be inclined so as to escape from the main control device 131. Thus, even if the key member K2 is mounted immediately beside the front case body 271, the key member K2 can be mounted without being obstructed by the front case body 271 or the like.

  Next, a procedure for removing the main control device 131 from the pedestal device 210 with the main board unit 200 attached to the back plate 11c of the housing 11 will be described with reference to FIG. 23A 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 FIG. FIG. 3C shows a state in which the main control device 131 is slid from the movable base plate 212 while the movable base plate 212 is being rotated. In FIG. 23, the lower side is the front of the slot machine, and the upper side is the rear of the slot machine.

  In the state (a), the fixed base plate 211 and the movable base plate 212 are in an overlapping state, and the locking claws 218 of the fixed base plate 211 are connected to the main controller 131 (actually, the front case body 271). It is locked on the upper surface of. Although not shown 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 cannot rotate with respect to the fixed base plate 211. At this time, the main controller 131 has its front surface facing the front side of the slot machine 10, and the main board surface, that is, the mounting surface of the IC chip or the like is visible from the front.

  Further, when the movable base plate 212 shown in (b) rotates, the key member (at least the key member K2 in FIG. 22) is removed, and the locking of the locking claw portion 218 of the fixed base plate 211 is released. In this state, the movable base plate 212 is rotated with respect to the fixed base plate 211 as shown. At this time, the movable base plate 212 is rotated about the support pin 217 as a rotation center by about 90 degrees at the maximum, and the rotating front end side of the main controller 131 is pulled toward the front side together with the movable base plate 212. In such a state, the back side of the main control device 131 (that is, the back side of the main board 273) can be visually recognized, and it is possible to confirm whether there is any abnormality or improperness in various electronic components, electric wiring, and the like.

  When the movable base plate 212 and the main control device 131 are rotated with respect to the fixed base plate 211 as shown in FIG. 2B, the main control device 131 is viewed obliquely from the side, from the state viewed from the front side. Transition to the state. Therefore, even if the information is attached to a portion that is difficult to visually recognize from the front of the main controller 131, that is, information attached to an upright surface portion that is substantially perpendicular to the substrate surface of the main substrate 273, the information is easily visible due to the rotation of the movable base plate 212. It can be. For example, in the case of 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 visually recognized.

  Incidentally, in the actual configuration of the slot machine 10, as shown in FIG. 5 and the like, the front space of the main control device 131 is opened, and there is no hindrance to the pivoting operation of the movable base plate 212 toward the front side. Will not occur. Even if a device or a mechanism that projects rearward of the slot machine is provided on the back surface of the front door 12, the front space of the main controller 131 is opened with the opening of the front door 12, and the rotating operation of the movable base plate 212 is also performed. No problem occurs.

  When the main controller 131 slides as shown in FIG. 23 (c), the key member (key member K1 in FIG. 22) is removed, and the first sealing portion (sealing between the movable base plate 212 and the front case body 271) is performed. ) Is opened. Further, the locking of the locking claw 295 provided at the left end of the front case body 271 and the screw fixing in the screw hole 296 are released. Then, main controller 131 slides on movable base plate 212 in this state. Thereby, the main control device 131 can be detached from the pivoting end portion side of the movable base plate 212 (the board mounting 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 equipped with a microcomputer centered on a CPU 151 serving as an arithmetic processing means. In addition to the power supply 161 provided inside the power supply box 121, a clock circuit 154 that outputs a rectangular wave of a predetermined frequency, an input / output port 155, and the like are connected to the CPU 151 via an internal bus. The main control device 131 functions as a main base built 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, 74a for individually detecting the operations of the respective stop switches 72, 73, 74, a medal slot. Switch 75 for detecting the operation of each of the credit insertion switches 77, 78 and 79, the credit insertion detection sensors 77a, 78a and 79a for individually detecting the operation of each of the credit insertion switches 77, 78 and 79, and the switch for detecting the operation of 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 paid out from the hopper device 91, and a reset detection sensor for detecting the operation of the reset switch 123. 123a, set in 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.

  Note that 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 so that medals can pass in one row. A first sensor is provided in the storage passage 81, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal (the degree that a state where the same medal is simultaneously detected at least at one time occurs). The first to third sensors constitute an inserted medal detection sensor 75a. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, it is regarded that there is a medal clogging or a fraud, and an error is generated. When an error occurs, an error is notified 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 sensor and the third sensor are turned on and off, and 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 medal has been taken normally only when the order is such that only the third sensor is on and both the second and third sensors are off and the time to shift to each on / off switching is within a predetermined time. Otherwise, an error occurs. This is to prevent medals from being clogged in the storage passage 81 and fraudulent misrecognition of medals being inserted by reciprocating the medals near the inserted medal detection sensor 75a.

  A power failure monitoring circuit 161b provided in the power supply 161 is connected to the input side of the main controller 131 via an input / output port 155. The power supply board 161 is provided with a power supply section 161a for supplying drive power to each electronic device of the slot machine 10 including the main controller 131, the above-described power failure monitoring circuit 161b, and the like.

  The power failure monitoring circuit 161b monitors the power-off state, and generates a power failure signal when the power is turned off by the power switch 122 as well as at the time of the power failure. Therefore, the power failure monitoring circuit 161b monitors the stabilized drive voltage of DC 12 volts output from the power supply unit 161a in this example, and determines that the power supply has been cut off when the drive voltage drops 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. The CPU 151 recognizes the power failure signal and executes a power failure process described later.

  Even when the output voltage drops to less than 22 volts, the power supply unit 161a outputs a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main controller 131. As the time during which the stabilized voltage is output, a time sufficient for executing the power failure process by the main control device 131 is secured.

  On the output side of the main controller 131, each of the activated line display units 32, 33, 34, the remaining number display unit 35, the number of games display unit 36, the acquired number display unit 37, and the reels 42L, 42M, 42R are rotated. The external centralized terminal board 171 that can transmit information to the stepping motors 61 (61L, 61M, 61R), the medal passage switching solenoid 83 provided in the selector 84, the hopper device 91, the display control device 111, and a hole management device (not shown). Are connected via an 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 board on which a CPU, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving the signal from the main control device 131, the display control device 111 independently drives and controls 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 that is a main base that comprehensively manages the game. That is, by providing a sub-base for sounds, lamps, and displays related to indirect games, the burden on the main base is reduced. Note that a configuration in which the display control device 111 controls the various display units 32 to 37 may be adopted.

  The CPU 151 includes a ROM 152 storing various control programs and fixed value data executed by the CPU 151, and a task of temporarily storing various data when executing the control programs stored in the ROM 152. In addition to the RAM 153 for securing the area, various processing circuits required in the slot machine 10, such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, and a credit counter (not shown), and a credit counter for counting the number of credits. And various other counters. The ROM 152 and the RAM 153 constitute a main memory as storage means, and a program for executing the processes shown in various flowcharts shown in FIG. 25 and thereafter is stored in the ROM 152 as a part of the control program.

  The RAM 153 has a configuration in which a backup voltage is supplied from the power supply device 161 provided in the power supply box 121 to retain data (backup) even after the power of the slot machine 10 is cut off. A backup area is provided in addition to a memory and an area for temporarily storing various data and the like.

  In the backup area, when the power is cut off due to the occurrence of a power failure or the like, the stack pointer, the value of each register, I / O, and the like at the time of the power cutoff (including the power cutoff by operating the power switch 122. The same applies hereinafter). When the power failure is turned off (including power-on by operating the power switch 122. The same applies hereinafter), the state of the slot machine 10 based on the information in the backup area before the power is turned off. It is possible to return to the state. The writing to the backup area is executed when the power is turned off by the process at the time of power failure (see FIG. 27), and the restoration of each value written to the backup area is executed in the main process when the power is turned on (see FIG. 28). The NMI terminal (non-maskable interrupt terminal) of the CPU 151 is configured to receive a power failure signal from the power failure monitoring circuit 161b when the power is shut off due to the occurrence of a power failure or the like. An NMI interrupt process as a flag generation process 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 a main processing started when the power is turned on, a timer interrupt processing started periodically (in this embodiment, at a period of 1.49 msec), and an NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by the input of the power failure signal of the above. 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 illustrating an example of the NMI interrupt process. When the power is cut off due to the occurrence of a power failure or the like, a power failure signal is generated in the power failure monitoring circuit 161b of the power supply device 161 and output to the main control device 131. The main controller 131 that has received the power failure signal via the NMI terminal executes an NMI interrupt process.

  In the NMI interrupt process, first, in 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, the power failure flag is set in a power failure flag storage area provided in the RAM 153. After that, the data saved in the backup area of the RAM 153 in step S103 is returned to the use register of the CPU 151 again. The NMI interrupt process ends with this return process. If the power failure flag can be set without destroying the data in the register used by the CPU 151, the process of saving and restoring to the backup area can be omitted.

  FIG. 26 is a flowchart of a 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 processing shown in step S201, the values of all registers in the CPU 151 used in the later-described normal processing 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, and the process at the time of power failure is executed.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register saving process in the timer interrupt process, it can be executed without interrupting other interrupt processes. Therefore, for example, during the transmission processing of various commands and during the reading processing of the switch state (on / off), the processing at the time of the power failure is not executed by interrupting each processing, but is executed at such timing. Therefore, it is not necessary to create a power failure processing program in consideration of the above. This makes it possible to simplify the processing program for power failure processing and reduce the program capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether the command transmission has been completed. If the transmission has not been completed, the process returns to the original process of FIG. As described above, it is determined whether or not the transmission of the command is completed at the initial stage of the process at the time of power failure, and when the transmission is not completed, the transmission process is prioritized, and the process at the time of power failure is performed after the transmission process of the unit command is completed. By doing so, there is no need to construct a power failure processing program that takes into account that the power failure processing is executed during the transmission of the command. As a result, there is an advantage that the power failure processing program can be simplified and the capacity of the ROM 152 can be reduced.

  If step S301 is YES, that is, if the command transmission has been 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, as a stop process, a RAM determination value to be described later is cleared, the output state of the output port in the input / output port 155 is cleared, and all actuators (not shown) are turned off. In step S304, a RAM determination value is calculated and stored in the backup area. The RAM determination value is, specifically, a two's complement of the checksum value in 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, further access to the RAM is prohibited in step S305. After that, an infinite loop is entered in preparation for the case where the power supply is completely cut off and processing cannot be executed.

  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 time sufficient to execute the above-described NMI interrupt processing and power failure processing. It is configured to: In the present embodiment, the drive voltage is continuously output for 30 msec.

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

  That is, in step S204, a clearing process of the watchdog timer for initializing the value of the watchdog timer for monitoring the occurrence of a malfunction is performed. In step S205, an interrupt end declaration process 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 for driving the stepping motors 61L to 61R, which are the respective drum drive motors, is performed. In step S207, a sensor monitoring process for monitoring the state of various sensors (see FIG. 24) connected to the input / output port 155 is performed. In step S208, a timer calculation process for subtracting the value of each counter or timer is performed. In step S209, a counter process for counting the number of medals bet and the number of payouts is performed.

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

  FIG. 28 is a flowchart showing main processing in main controller 131 executed after power-on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, a value of a stack pointer is set in the CPU 151, and an interrupt mode for permitting interrupt processing is set. Thereafter, various settings for a register group in the CPU 151, an I / O device, and the like are performed. And so on.

  When these initialization processes have been completed, it is next determined in step S402 whether or not the reset switch 123 has been turned on. If the reset switch 123 has been turned on, the flow advances to step S403 to clear all data stored in the RAM 153 as RAM clear processing.

  After confirming that the reset switch has not been operated in step S402, or performing RAM clear processing in step S403, it is determined in step S404 whether the setting key has been inserted into the setting key insertion hole 124. I do. If the setting key has been inserted, the flow advances to step S405 to perform a setting change process. As a setting change process, first, all data stored in the RAM 153 is cleared. Then, after determining which setting state has been selected from the preset six setting states (“Setting 1” to “Setting 6”), the internal processing corresponding 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 has not been set, that is, if the data of the RAM 153 has been cleared in the previous step S403 or S405, the process proceeds to a normal process in step S407 described later, and this process ends.

  When the power failure flag is set in step S406, the process proceeds to the power recovery process shown in step S408 and thereafter. The fact that the power failure flag is set means that no subroutine processing such as the RAM clear processing in step S403 and the setting change processing in step S405 has been executed. Therefore, the data in the RAM 153 has not been rewritten at all, and in the power recovery process, it is necessary to perform a process of checking whether the data in the RAM 153 is normal or not.

  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 to determine whether the value is normal, that is, whether the checksum taking the RAM determination value into consideration is 0 or not. If the value of the checksum in consideration of 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 in step S408, that is, if the checksum value is not 0, it is highly likely that the data in the RAM 153 has been destroyed. Therefore, in such a case, an error display process is performed in step S409. As error display processing, first, interrupt processing is prohibited, and all output ports in the input / output port 155 are cleared, thereby controlling all actuators connected to the input / output port 155 to the off state. Thereafter, an error display for notifying the occurrence of an error to a hall manager or the like is performed, and the 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, in which 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 before power is cut off. Return to the state. Next, in step S411, a power restoration command notifying the execution of the power restoration process is transmitted to the display control device 111. Then, in step S412, the game is stopped as a game state and an automatic payment setting and saving process is performed. In step S413, various sensors such as the start detection sensor 71a are initialized. After the above processing 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 relating to a game will be described with reference to the flowchart in FIG.

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

  Next, the lottery process in step S503 will be described with reference to the flowchart in FIG.

  In step S601, based on the current setting state of the slot machine 10, the number of medals bet, the level of small combination probability, and the like, a random number table for determining whether to win or not is selected. Here, the setting state of the slot machine 10 is any one of “Setting 1” to “Setting 6” set by using a setting key (not shown). A table is selected, and a random number table having the highest winning probability of a combination at the time of “setting 6” is selected. The number of medals bet is one of one to three, and a random number table is selected such that the greater the number of bets, the higher the probability of winning a role. For example, the winning probability of a hand when three bets are placed is three times higher than the winning probability of a hand when one bet is placed. Further, there are two types of small hand probability, high and low. When the present payout rate is below a predetermined expected value, a random number table having a high small hand winning probability is selected, and when the present winning percentage is above a predetermined expected value, a small random number table is selected. A random number table with a low winning probability is selected.

  In step S602, the random number table selected in this way is lit by the random number latched by the random number counter when the start lever 71 is operated, and a lottery of a winning combination is performed. Then, in step S603, it is determined whether or not any of the winning combinations has been won. If no winning combination has been won, the present process ends. If any of the winning combinations has been won, the process proceeds to step S604, in which a winning flag corresponding to the winning combination is set, and an effective line on which symbols are to be aligned is determined. Subsequently, in step S605, a slip table for reel stop control is determined and stored in the slip table storage area of the RAM 153. Here, when the symbol on the predetermined effective line at the timing when the stop switches 72 to 74 are pressed and the symbol to be stopped on the effective line are different, the slip table is a predetermined symbol to be stopped. Is a table that determines how much the reels are slid so as to stop on the active line.

  Next, the reel control processing in step S504 will be described based on the flowchart in FIG.

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

  On the other hand, if any one of the stop switches 72 to 74 is pressed to generate a stop command in step S703, the process proceeds to step S706 to perform a reel stop process. In this reel stop processing, the reel corresponding to the pressed stop switch is stopped. However, when the winning is won in the lottery of the winning and the winning flag is set, the reel is stored in the sliding table storage area of the RAM 153. With reference to the sliding table, control is performed so that the winning combinations are lined up on predetermined effective lines as much as possible. For example, if the player wins the role of “watermelon” symbols lining up on the lower line, and the stop switch is pressed at the timing when the “watermelon” symbols stop on the upper line, the symbol 2 stops so as to stop on the lower line. Slide the reel one time. However, the range that can be slid is predetermined (for example, a maximum of four symbols), so the “watermelon” symbol may not stop on the lower line depending on the timing of pressing the stop switch. In the forced stop process in 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 a slide table changing process is performed. In this sliding table change processing, for example, it is determined whether or not a combination of a role occurs when trying to align a combination on a winning line that has been won. If the combination of a role does not occur, the process proceeds to the next step as it is, When a combination of winning combinations occurs, the selected activated line is changed to another activated line, and is changed to a sliding table suitable for the activated line after the change, and then the process proceeds to the next step. Here, the combination of a combination means that, for example, when trying to align the "watermelon" symbol on the upper line, a plurality of roles are simultaneously generated as in the case where the "cherry" symbol appears on the lower line on the left reel. Say the case. Note that the slide table changing process may be performed other than when avoiding combination of roles.

  On the other hand, if the current stop command is not the first stop command in step S707, the process advances to step S709 to determine whether the command is the second stop command, that is, one of the three reels is stopped and the two reels are rotating. It is determined whether or not the stop switch has been pressed. When the command is the second stop command, the process proceeds to step S710 to perform a stop-eye determination process. In this stop-eye determination processing, when the two reels have stopped, it is determined whether or not the two reels are aligned with a bonus symbol such as a “7” symbol. If so, the process proceeds to the next step after generating a sound effect or the like from the speaker 14. In the stop-eye determination processing, it may be determined whether or not another condition other than the arrangement of two bonus symbols is satisfied, or an effect using the auxiliary display unit 15 other than the sound effect may be performed.

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

  Next, the medal payout process in step S505 will be described with reference to the flowchart in FIG.

  In the medal payout processing, first, it is determined whether or not the payout number counted by the payout number counter in step S801 matches the expected payout number stored in the expected payout number storage area. If the number of payouts does not match the expected number of payouts, it is determined in step S802 whether the game is being played in the credit mode. When the credit mode is set, it is determined in step S803 whether or not the count value of the credit counter has reached an 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 each incremented by one in step S804. Thereby, the numbers of the remaining number display section 35 and the acquired number display section 37 are each incremented by one.

  On the other hand, when the game is being played in the direct mode, or when the count value of the credit counter has reached the upper limit, the medal payout rotating plate is driven in step S805 to transfer the medal from the hopper device 91 to the medal discharge port. Payout to the medal tray 18 via 17. At this time, in step S806, the payout number is incremented by one according to the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. As a result, the number of the acquired number display section 37 is incremented by one. Then, after the payout number is incremented by one in step S804 or step S806, the process returns to step S801. If the number of payouts matches the expected number of payouts in step S801, the medal payout rotating plate of the hopper device 91 is stopped in step S807, and this processing ends. Note that the payout number and the acquired number display units 37 are reset the next time the start lever 71 is operated.

  Next, the special game state process in step S506 will be described with reference to the flowchart in FIG.

  Prior to the description of the special game state process, a 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 allowed, and has a very high probability that JAC symbols (here, substitutes for replay symbols) will be aligned on the active line, that is, the probability of JAC symbol establishment. When the JAC symbol is established in the JAC game, the maximum number of medals (here, 15) is paid out. Then, when the JAC symbol is formed eight times, the RB game ends 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. The small role game is a game in which the small role is won with a high probability (the "bell" symbol etc. are aligned on the activated line). The JAC in means that the player enters 12 JAC games, When the JAC symbols are aligned on the active line, the JAC-in is established. The JAC game is the same as the RB game. In addition, when the JAC game with the third JAC-in ends, the BB game ends even before the small role game reaches 30 times, and when the 30th small role game ends, before the JAC-in reaches 3 times. If so, the BB game ends.

  In the special game state process, first, in step S901, it is determined whether the game state is a bonus game. If it is not during the bonus game, 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 in step S1001 whether or not the RB winning flag has been set, and if so, the process proceeds to step S1002, where the RB symbol is displayed on the current pay line. It is determined whether or not (for example, “BAR” symbols) are complete, and if the RB symbols are not complete, the process is terminated as it is. On the other hand, when the RB symbols are aligned on the active line this time, the RB winning flag is reset and the RB setting flag is set in step S1003 to set the RB game as one of the bonus games, and the RB game initial setting process shown in FIG. To end the present process. If the RB winning flag has not been set in step S1001, it is determined in step S1004 whether or not the BB winning flag has been set. If not, the present processing ends. When the BB winning flag is set, the process proceeds to step S1005, and it is determined whether a BB symbol (for example, symbol "7") is aligned on the current activated line. . On the other hand, when the BB symbols are aligned on the pay line this time, the BB winning flag is reset and the BB setting flag is set in step S1006 to set the BB game as one of the bonus games, and the BB game initial setting process shown in FIG. Execute and end this process.

  In FIGS. 35 and 36, the remaining small role game counter indicates the number of remaining small role games (also referred to as the number of remaining small role games), and the remaining JAC in counter indicates the remaining number of possible JAC ins (the number of remaining JAC ins). The remaining JAC establishment counter indicates the number of remaining JAC symbols that can be established (also referred to as the number of remaining JAC establishments), and the remaining JAC game counter indicates the remaining number of JAC games (also referred to as the remaining JAC game number). Represent. The number of remaining small role games, the number of remaining JAC ins, the number of remaining JACs, and the number of remaining JAC games are displayed on the game number display section 36 as appropriate. By the way, when the small role or replay winning flag or the replay winning flag is set by winning the small role or replay in the lottery of the role, the small role symbol or the replay symbol cannot be aligned on the activated line in the game, and the winning flag is determined. Is reset, but when the RB or BB winning flag is set by winning the RB or BB by the lottery of the role, even if the RB symbol or the BB symbol cannot be aligned on the active line in the game, Will be carried over the next time. In the lottery process in the next game in which the BB or RB winning flag is carried over, the lottery regarding whether or not the winning of the small role or the replay is performed is performed, but the BB or RB is not performed. When a win or small replay is won while the BB or RB win flag is carried over, a slip table is stored so that the small win or replay is preferentially aligned.

  Now, returning to FIG. 33, when the gaming state is during the bonus game in step S901, it is determined in step S903 whether or not the bonus game is a JAC game. If it is not a JAC game, it means that the small role game of the BB game is being played, so the process proceeds to step S904, and it is determined whether or not the JAC symbols are aligned on the activated line. When the JAC symbols are aligned on the active line, the JAC game is started in step S905, the JAC game initial setting process during the BB game shown in FIG. 36B is performed, and the process ends. On the other hand, when the JAC symbols are not aligned on the activated line in step S904, one small game has been consumed, so the number of remaining small combination games is decremented by 1 in step S906, and in step S907. It is determined whether or not the number of remaining small role games has become zero. When the number of remaining small role games is not 0, the present processing is ended. When the number of remaining small winning games is 0, the process proceeds to step S908, and a special game state ending process in which various setting flags, BB setting flags, various counters, etc. are appropriately reset or an ending process is performed. Is performed, and this processing ends.

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

  On the other hand, if the number of remaining JAC-ins is not zero in step S914, that is, if the JAC-in has not been consumed three times in the BB game, a JAC game end process for resetting the JAC game setting flag is performed in step S915, and then the current JAC-in is executed. Since one small role game is consumed when the player enters the game, the number of remaining small role games is decremented by 1 in step S906, and it is determined in step S907 whether the number of remaining small role games has become zero. If it is determined that the number of remaining small role games is 0, the special game state ending process of step S908 described above is performed, and this process ends. On the other hand, if the number of remaining small role games is not 0, the number of small role games in the BB bonus has not reached 30 and the number of JAC-ins has not reached three, so this processing ends.

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

  In the main board unit 200 attached to the back plate 11c of the housing 11, the movable base plate 212 on which the main control device 131 is mounted is rotatable with respect to the fixed base plate 211. The back surface (main substrate back surface) of control device 131 is opened. Therefore, it is possible to check on the back side whether there is any abnormality or improperness in various electronic components, electric wiring, and the like. Further, when the movable base plate 212 rotates, the side surface information of the vertical element (IC chip 274) mounted on the main substrate 273 can be easily read by tilting the substrate surface of the main control device 131. It is possible to confirm that the element can be genuine. As a result, it is possible to confirm that an improper act has not been performed in the main control device 131, and as a result, the main control device 131 can be properly managed.

  When an electronic component other than the vertical element is mounted parallel to the substrate surface, another unauthorized electronic component (illegal IC) is attached to the lower side of the electronic component (that is, between the electronic component and the substrate). Although there are various types of misconduct, as described above, the movable base plate 212 on which the main controller 131 is mounted is rotatable with respect to the fixed base plate 211, so that countermeasures against such misconduct can be realized. In other words, it is difficult to find a fraudulent IC hidden under a legitimate electronic component only by looking at the front side of the main controller 131 from the front, but by rotating the movable base plate 212, the fraudulent IC is removed. Can be easily found.

  The effect of attaching the main board unit 200 to the back plate 11c on the inner peripheral surface of the housing 11 is that it is difficult to remove the main control device 131 illegally. It is difficult to perform unauthorized work on the main control device 131, and the distance between the main control device 131 and the front open portion of the housing 11 is long, so that an illegal signal line is connected to the main control device 131 through the front open portion of the housing 11. When the front door 12 is opened, the main control device 131 is in front, so that the front surface of the main control device 131 can be easily detected, and the width of the board is larger than the side plates 11d and 11e. And the like.

  By sliding the main control device 131 on the movable base plate 212 in a state where the movable base plate 212 is rotated, the main control device 131 can be attached and detached from the rotation front end side of the movable base plate 212. As a result, main controller 131 can be easily attached or detached in a state where the rotating distal end of movable base plate 212 is pulled toward the near side. Therefore, workability at the time of inspection or replacement of main controller 131 can be improved.

  Since the fixed base plate 211 is fastened from the outside of the housing using the screw 233 with the back plate 11c of the housing 11 interposed therebetween, for example, when a large number of slot machines 10 are installed in a game hall, the fixed base plate 211 is fixed. It becomes extremely difficult to remove the main control device 131. As a result, unauthorized removal of the main control device 131 can be suppressed. Thereby, it is possible to suppress an illegal act of carrying out (stealing) not only the main control device 131 but also the pedestal device 210 collectively.

  The present invention is not limited to the description of the above-described embodiment, and may be implemented as follows, for example.

  (A) In the above-described embodiment, the main board unit 200 is attached to the back plate 11c of the housing 11, but instead the main board unit 200 is mounted on the left or right side plate 11d, 11e of the housing 11. It is good also as composition attached to. Even if it is attached to either of the left and right side plates 11 d and 11 e of the housing 11, the main control device 131 is moved to the front side (that is, the slot machine) by enabling the rotation base plate 112 to rotate with respect to the fixed base plate 211. 10 forward), which provides an excellent effect as described above.

  (B) In the above embodiment, the fixed base plate 211 and the movable base plate 212 are rotatably connected using the support pins 217 press-fitted into the shaft holes, but this configuration is changed. For example, a configuration may be adopted in which a support portion is integrally formed on either the fixed base plate 211 or the movable base plate 212, and the fixed base plate 211 and the movable base plate 212 are rotationally connected by the support portion. Any configuration can be applied as long as the base plates 211 and 212 are rotatable and cannot be separated (uncoupled).

  (C) In the above-described 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 (board box), but this configuration is changed. For example, the movable base plate 212 is made smaller than the main controller 131 (substrate box). Specifically, a configuration in which the length of the movable base plate 212 in the longitudinal direction is set to 2/3, 1/2, or 1/3 of the length of the main control device 131 is conceivable. Alternatively, the bottom plate portion 241 of the movable base plate 212 may be partially cut out including the center portion, and a configuration may be adopted in which a transparent window is provided in the bottom plate portion 241. In any case, any configuration may be used as long as the movable base plate 212 is rotated so that the back surface of the main controller 131 can be easily confirmed. The fixed base plate 211 may be smaller or larger than the main controller 131 on the assumption that the main controller 131 can be securely mounted.

  (D) In the above embodiment, the pivot support is provided on the short side of the fixed base plate 211. However, the configuration may be such that the pivot support is provided on the long side of the fixed base plate 211. In this case, the amount by which the movable base plate 212 is pulled toward the front side is reduced, but the facing angle of the main control device 131 when viewed from the front of the slot machine is the same. (The same applies to reading the side information of the IC chip 274).

  (E) In the above embodiment, both the fixed base plate 211 and the movable base plate 212 constituting the pedestal member 210 are formed of a transparent synthetic resin material, but the fixed base plate 211 is formed of a colored resin material. Alternatively, the fixed base plate 211 may be formed of a material other than a resin material, such as a metal. In addition, since the movable base plate 212 only needs to be able to visually recognize the back surface of the main control device 131, if a configuration such as providing a viewing window in the bottom plate portion 241 of the movable base plate 212 is added, the movable base plate 212 may be changed to a colored resin material. The material may be changed to a material other than the resin material, such as a metal.

  (F) In the above embodiment, the main control device 131 is guided on the movable base plate 212 in the sliding direction, and the return portions are formed over the entire length of the side plate portions 242 and 243 in order to hold the main control device 131 integrally. Although 242a and 243a are provided (see FIG. 12), the return portions 242a and 243a near the board mounting port 245 may be partially removed. For example, in the configuration of FIG. 12, two return portions 242a and 243a from the right are removed. By partially removing the return portions 242a and 243a, the required amount of sliding of the main control device 131 on the movable base plate 212 is reduced, and the attachment and detachment of the main control device 131 is facilitated.

  (G) The second pedestal member (movable base plate 212) may have a double-opening structure capable of rotating (opening) to the left and right sides. More specifically, a rotating shaft is provided on each of the left and right ends of the fixed base plate 211 so that the movable base plate 212 can be rotated in two opposite directions about each rotating shaft. Thus, for example, at the left and right ends of the main control device 131 (control board device), it is possible to draw a worker or the like to the front side.

  (H) A second base member (movable base plate 212) is mounted on a first base member (fixed base plate 211) so as to be rotatable and a control base device (main control device 131). It is also possible to adopt a configuration in which the substrate mounting portion is constituted by a substrate mounting portion, and the substrate mounting portion is connected to the rotating base so that the substrate mounting portion can be inverted. According to this configuration, by rotating the rotation base with respect to the first pedestal member and further turning the board mounting portion upside down with respect to the rotation base, the housing facing surface of the control board device can be easily confirmed. become able to.

  (I) In the above embodiment, the movable base plate 212 is provided rotatably with respect to the fixed base plate 211 in the main board unit 200, but this configuration is changed as follows. For example, an extensible leg (specifically, an X-type telescopic link) is provided between the fixed base plate 211 and the movable base plate 212 and the base plates 211 and 212 are overlapped by contracting the leg. In this state, the movable base plate 212 is separated from the fixed base plate 211 by extending the legs so that the main control device 131 is pulled toward the user. In this case, the movable base plate 212 can be moved so as to move in parallel with the fixed base plate 211. Also, two left and right legs are provided between the fixed base plate 211 and the movable base plate 212, and these legs are independently extended and contracted. According to this configuration, main controller 131 can be pulled in a state of being tilted to the left or right.

  (J) Illuminating means such as a lamp is provided inside the housing 11, and the lamp or the like (illuminating means) is turned on when the movable base plate 212 is rotated with respect to the fixed base plate 211. Accordingly, it is possible to easily confirm whether or not there is an illegal act on the main control device 131 and the pedestal device 210. The lighting means may be attached to the housing 11 or to the pedestal device 210.

  (K) In the above-described embodiment, in the first sealing portion of the main board unit 200, the insertion-side coupling portions 291 are arranged in quadruple on the front case body 271 and the receiving-side coupling portions 251 are correspondingly arranged. Although four units are provided side by side on the movable base plate 212, this configuration is changed. At least one of the four receiving coupling portions is provided on the back case body 272. Even with this configuration, an appropriate sealing structure can be realized.

  (L) The configuration of the sealing portion of the main control device 131 can be changed in another way. Regarding the location where the sealing portion is provided, the sealing portion may be provided on both the left and right short sides of the board box (case bodies 271 and 272), and may be provided on the long side of the board box (case bodies 271 and 272). Further, instead of the configuration using the sealing screw, a configuration in which a sealing metal piece is inserted into the sealing connecting portion may be used.

  (M) In the above embodiment, in order to fixedly attach the fixed base plate 211 to the back plate 11c of the housing 11, fastening is performed by two screws 223 from the inside of the housing and from the outside of the housing to the center. Although the configuration is such that the fastening is performed by one screw 233, this configuration is changed. For example, a configuration may be adopted in which the fixed base plate 211 is fastened only from the outside of the housing. In such a case, the number of fastening locations (specifically, the locations where the fixing brackets 225 are installed) may be two or more.

  (N) In the above embodiment, the configuration is adopted in which the pedestal device is rotated with respect to the main control device 131 including the main board 273. However, a similar configuration is provided for other control devices other than the main control device 131. Is also good.

  (O) In the above embodiment, the pedestal device 210 is composed of two pedestal members (the fixed base plate 211 and the movable base plate 212), and the main control device 131 is provided on one of the pedestal members (the movable base plate 212). But this is changed as follows. The pedestal device is composed of one pedestal member, and the pedestal member is fixed to the back plate 11 c of the housing 11. Then, the main control device is rotatably (or displaceably) connected to the pedestal member. Even in this configuration, it is still possible to easily check the back surface (the surface facing the housing) of the main control device.

  (P) The gaming machine can be applied to other than the slot machine. The point is that the gaming machine has a housing that is open on the front side, and the control board device is housed inside the housing. The present invention can be suitably realized with a gaming machine.
