Description

  The present invention relates to a gaming machine such as a slot machine.

  A gaming machine such as a slot machine is provided with a control board device for carrying out various controls relating to the game, and the control board device performs control of symbols that are displayed in a variable manner at each game, lottery drawing, and the like. . A microcomputer that executes various processes, a memory (ROM) that stores control information related to game contents, and the like are mounted on a control board constituting the control board device. A control board device is configured by housing the control board in a board box. In general, in a configuration having a casing as a gaming machine main body like a slot machine, for example, a control board device is disposed so as to face a back plate of the casing.

  In this type of gaming machine, for the purpose of obtaining illegal profits, the control board device is illegally removed and the ROM in the device is replaced to change the game contents, or illegal electric power is externally connected by a jumper wire or the like. Many fraudulent acts against the control board device, such as inputting a signal to the control board, have been reported, and various countermeasures against fraud have been studied. For example, the board box is configured with a transparent case body so that the state of the control board can be easily seen from the outside. The board box has a sealing structure so that the opening history due to breakage or the like remains when the board box is opened. Or, an improper measure such as sticking a non-re-stickable seal seal to a joint portion between a pair of upper and lower case bodies constituting the substrate box is employed (see, for example, Patent Document 1).

  However, even if the above-mentioned fraud countermeasures are taken, it is still the case that fraudulent acts are still being carried out, and even if the control board device adopts the sealing structure or the sealing seal, The board box is cleverly opened so as not to remain, and the internal control board is fraudulently performed. In addition, if fraudulent acts are carried out, it is important to detect the fraudulent acts more quickly and reliably. However, there are many cases where fraudulent acts cannot be confirmed at first glance, and fraud countermeasures are not sufficient. The problem remains.

In the case of a gaming machine (for example, a slot machine) in which the control board device is attached to the back plate or the like of the housing, the control board device is confirmed from the front side of the gaming machine with the front door opened. At this time, the control board device is normally checked by looking into the inside of the housing from the front opening portion of the housing. However, as described above, if the cheating is performed skillfully, the housing is viewed from the front of the gaming machine. It was difficult to confirm fraud by simply looking inside, and there was a risk of overlooking fraud.

  A game panel 30 for notifying the player of the game state is provided above the center of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R each formed in a cylindrical shape (annular shape). The reels 42L, 42M, and 42R may be configured as at least an endless belt, and are not limited to a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R correspond to the display windows 31L, 31M, and 31R on a one-to-one basis. . Accordingly, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R. Further, when the reels 42L, 42M, and 42R are rotated forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  Each of the reels 42L, 42M, and 42R is coupled to the stepping motors 61L, 61M, and 61R, and each of the reels 42L, 42M, and 42R is individually, that is, independently, driven by the stepping motors 61L, 61M, and 61R. Thus, it can be rotationally driven. Since these reels 42L, 42M, and 42R have the same configuration, here, the left reel 42L will be described as an example with reference to FIG. FIG. 6 is an assembled perspective view of the left reel 42L.

  The left reel 42L includes a cylindrical skeleton member 50 that forms a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical skeleton member 50 through a pair of seal parts formed along the both sides of the long side of the belt so as to maintain the wound state. 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 skeleton 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 is rotated, the cylindrical skeleton member 50 is rotated around the drive shaft so that the left reel 42L circulates along the annular reel surface. It has become.

  The left reel stepping motor 61L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) with screws 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42L with a screw 57. The front end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is positioned so as to pass between both elements 55a and 55b of the reel index sensor 55. Each 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 controller 131 described later each time the detection is made. 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 rotate once by giving, for example, 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, left The rotational position of the reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, and 42R, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. 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. It is possible to perform control to achieve a proper state.

  Of the symbols attached to the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

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

  As the symbols, there are a “7” symbol (for example, the left belt 20th) and a “youth” symbol (for example, the left belt 19th) 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 the second special symbol for shifting to the regular bonus game. Further, there is a “replay” symbol (for example, the eleventh left belt) as a third special symbol for shifting to the replay game. In addition, a “watermelon” symbol (for example, the left belt ninth), a “bell” symbol (for example, the left belt eighth), and a “cherry” symbol (for example, left) as the small character symbols from which the small character is paid out. Belt 4th). As shown in FIG. 7, the number of various symbols and the arrangement order are completely different in the belt wound around each reel 42L, 42M, 42R.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying identification information, and constitutes a main display unit. However, the variable display means may have other configurations. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used, and instead of or in addition to the mechanical reel configuration, a liquid crystal display or a dot matrix display It is also possible to provide a display that variably displays the identification information by electrical display such as, and in this case, it is possible to provide a variety of display forms.

  A total of five combination lines are attached to the game panel 30 so as to connect the display windows 31L, 31M, and 31R, three in parallel in the horizontal direction and two in the diagonal direction. Of course, the maximum number of combination lines may be 6 or more, or 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 sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. The second effective line display unit 33 is notified by lighting or the like when the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (a right-down line and a right-up line) among the combination lines is enabled. Then, when the symbols are stopped in a predetermined combination on the activated combination line, that is, on the activated line, a winning is made, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the payout number regarding each symbol when winning is explained. Regarding the small role design, when the “Watermelon” design is aligned with the left, middle and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle and right on the effective line Pays out 8 medals, and when the “cherry” symbol on the left reel 42L stops on the active line, 2 medals are paid out. That is, the “cherry” symbols of the middle reel 42M and the right reel 42R are irrelevant to the medal payout. In addition, for the “cherry” symbol, the medal payout is performed regardless of the combination with other symbols, and therefore, a plurality of effective lines of the left reel 42L overlap (specifically, the upper or lower row) with “ When the “cherry” symbol is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this 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, middle and right on the active line in the same symbol The 15 medals are also paid out when the “BAR” symbol which is a combination of 15 medal payouts and the second special symbol (regular bonus symbol) is aligned with the left, middle and right on the active line. In the present embodiment, for example, a case where the “7” symbol and the “cherry” symbol are established simultaneously may occur, but in this case, 15 medals are paid out. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” symbol, which is the combination of the third special symbol, is aligned with the left, middle, and right on the active 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 active line and the same symbols as the left, middle, and right are not aligned on the active line, no medal payout is performed.

  On the lower left side of the game panel 30, a start lever 71 is provided that is operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously). The start lever 71 constitutes start operation means or start operation means operated to start rotation of the reels 42L, 42M, and 42R, that is, to start variable display. The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 52 is operated while a medal is inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Each of the stop switches 72, 73, 74 is arranged directly 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 of the stop switches 72, 73, 74 can be stopped when each of the reels 42L, 42M, 42R is rotated at a constant speed, and a stop operation is performed by lighting a lamp (not shown) during such a state. It is notified that this is possible, and is turned off when the rotation stops.

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

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

  FIG. 18 (end view taken along the line BB 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 in this state, the hook portion 312 is formed in the long hole 286 on the front case body 271 side. Locked to the locking portion 286a. Accordingly, the front case body 271 is held without being lifted with respect to the back case body 272. 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 laterally with respect to the back case body 272. Assuming that the front case body 271 is not attached to the rear case body 271, the front case body 271 is once slid rightward 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 in the middle).

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

  Returning to FIG. 13 again, a pair of upper and lower extension portions 314a and 314b are provided at the left end portion of the back case body 272 so as to extend leftward from the bottom plate portion 311. Each of the portions 314a and 314b is provided with a seal coupling portion 315 constituting the second seal portion. The seal coupling portion 315 has a cylindrical shape whose bottom is closed with the same surface as the bottom plate portion 311 and is open only on the front side of the figure. The extending portions 314a and 314b are provided separately in the vertical direction, and the space between the extending portions 314a and 314b is for avoiding interference with the plurality of seal coupling portions 251 provided on the movable base plate 212. It is an empty space.

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

  In addition, a plurality of (two in the present embodiment) seal coupling portions 317 constituting the third seal portion are provided at the right end portion of the back case body 272. The seal coupling portion 317 is connected to the back case body 272 by a connecting portion 318. By cutting the connecting portion 318, the seal coupling portion 317 can be excised from the back case body 272.

  Here, a sealing structure for suppressing the 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 each having a different sealing structure are provided, and for convenience, they will be described as a first sealing portion, a second sealing portion, and a third sealing portion in order. FIG. 19 corresponds to the end view taken along the line CC of FIG. 8, and shows a cross-sectional structure of the first sealing portion. FIG. 20 is an end view taken along the line DD of FIG. 8 and shows a cross-sectional structure of the second sealing portion. FIG. 21 is an end view taken along line EE in FIG. 8 and shows a cross-sectional structure of the third sealing portion.

  First, the structure of a 1st sealing part is demonstrated based on FIG. In FIG. 19, (a) shows the state before sealing, (b) shows the sealing state, and (c) shows the sealing release state. The first sealing portion can be in a sealed state by the combination of 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 former is referred to as “insertion”. The description will proceed by rephrasing the “side coupling portion 291” and the latter as “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 portion 291a (referred to as an upper hole portion for the sake of convenience) penetrating in the vertical direction. The receiving-side coupling portion 251 of the plate 212 is formed with a hole portion 251a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 291a. A stepped portion 291b is provided at the inlet portion of the upper hole portion 291a, and an enlarged diameter portion 251b having a diameter larger than that of the upper hole portion 291a is provided at the inlet portion of the lower hole portion 251a.

  Reference numerals 251c and 291c are semicircular return portions provided in the receiving side coupling portion 251 and the insertion side coupling portion 291 respectively (the return portion 251c is located at the front of the main controller 131 in the sliding direction, and the return portion 291c is provided behind the main controller 131 in the sliding direction), and 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 251c and 291c.

  At the time of carrying out the sealing process, as shown in FIG. 19B, the holes 291a and 251a of the insertion side coupling part 291 and the receiving side coupling part 251 are made of, for example, a synthetic resin and have 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-shaped head portion 321b, and two locking claw portions 321c that are provided at the cylindrical portion 321a and can be elastically deformed, for example. In a 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. Yes. Identification information (for example, 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 inserted until the head portion 321b hits the step portion 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 surface of the locking claw portion 321c is connected to the insertion side. The front end surface of the portion 291 is locked. Thereby, the sealing of the first sealing part is completed, and the sealing pin member 321 after the sealing is prevented from falling off.

  When the seal of the first seal portion is to be released in the event of a malfunction or inspection of the main controller 131, as shown in FIG. 19 (c), the insertion side coupling portion 291 and the front case body 271 are connected. The connecting portion 292 to be connected is cut with a tool such as a nipper. At this time, only the distal end portion of the sealing pin member 321 is inserted into the receiving side coupling portion 251, and since these members 251 and 321 are not in any locked state, they are inserted by cutting the connecting portion 292. The side coupling portion 291 and the sealing pin member 321 can be easily removed from the front case body 271. The cut-out insertion side coupling portion 291 and the sealing pin member 321 can be easily separated by pressing the locking claw portion 321c of the sealing pin member 321 with a finger or a tool and elastically deforming it. The separated sealing pin member 321 is not deformed or broken at all, and the same sealing pin member 321 is used for the next sealing.

  As described above, the identification information for each main controller 131 is attached to the head 321b of the sealing pin member 321. Therefore, after the sealing process is performed again by the reuse of the sealing pin member 321, the identification information is stored. By checking, it can be confirmed whether or not the sealing process has been performed in accordance with the regular procedure.

  When the seal of the first seal part is released, only the connecting part 292 on the front case body 271 side is cut (destroyed), and the movable base plate 212 is not destroyed anywhere in this case. 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 no sealing history remains. 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.

  Note that in the first sealing portion, which of the four sealing locations is used is determined in advance. For example, the sealing is performed one by one from the top in FIG. The sealing history remains at the sealed portion where the cutting process (destructive process) has been performed after sealing, and it is possible to easily confirm how many times the sealing process has been performed in the past.

  Next, the structure of a 2nd sealing part is demonstrated based on FIG. The second sealing portion can be in a sealed state by the combination of the sealing coupling portion 293 provided on the front case body 271 and the sealing coupling portion 315 provided on the back case body 272. The description will proceed by rephrasing the “side coupling portion 293” and the latter as “receiving side coupling portion 315”.

  As shown in FIG. 20, the insertion-side coupling portion 293 of the front case body 271 is formed with a hole portion 293 a (referred to as an upper hole portion for convenience) penetrating in the vertical direction. The receiving side coupling portion 315 is formed with a hole portion 315a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 293a. The upper hole portion 293a is formed with a large-diameter portion for accommodating a head of a sealing screw 323, which will be described later, and a small-diameter portion having a smaller diameter. A female screw part is formed in the lower hole part 315a. And the sealing screw 323 is screwed in each hole 293a, 315a of the insertion side coupling | bond part 293 and the receiving side coupling | bond part 315, and the sealing of a 2nd sealing part is completed. The sealing screw 323 is configured by a so-called breaking screw having a breakable portion (reduced diameter portion) that is easily broken at an intermediate portion, and when the screw 323 is screwed with a tightening tool such as a driver, a predetermined torque or more is applied. The rupture portion is broken. Due to this breakage, once the sealing screw 323 is screwed into the holes 293a and 315a, it becomes impossible to loosen the screw 323 thereafter.

  In order to release the seal of the second sealing part, the connecting part 294 that connects the insertion side connecting part 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 part The bottom part of 315 is cut | disconnected with tools, such as a nipper, (X2 part of a figure). That is, a vertical cutting process and a horizontal cutting process orthogonal to the vertical cutting process are performed. Thereby, 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 structure of a 3rd sealing part is demonstrated based on FIG. The third sealing portion can be brought into a sealed state by the combination of the sealing coupling portion 301 provided on the front case body 271 and the sealing coupling portion 317 provided on the back case body 272. The description will proceed by rephrasing the “side coupling portion 301” and the latter as “receiving side 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 portion 301 a (referred to as an upper hole portion for convenience) penetrating in the vertical direction. The receiving side coupling portion 317 is formed with a hole portion 317a (referred to as a lower hole portion for convenience) that communicates coaxially with the upper hole portion 301a. The upper hole portion 301a is formed with a large-diameter portion for accommodating a head of a sealing screw 325, which will be described later, and a small-diameter portion having a smaller diameter. A female screw portion is formed in the lower hole portion 317a. And the sealing screw 325 is screwed in each hole 301a, 317a of the insertion side coupling | bond part 301 and the receiving side coupling | bond part 317, and the sealing of a 3rd sealing part is completed. The sealing screw 325 is a so-called one-way screw (also referred to as a one-way screw) that can be screwed with a tightening tool such as a screwdriver in the tightening direction but cannot be loosened in the loosening direction. Once 325 is screwed into the holes 301a, 317a, it is impossible to loosen the screw 325 thereafter.

  To release the seal of the third sealing portion, a connecting portion 302 that connects the insertion side connecting portion 301 and the front case body 271, a connecting portion 318 that connects the receiving side connecting portion 317 and the back case body 272, Are cut together with a tool such as a nipper (X3 portion 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 has been described that both the second sealing portion and the third sealing portion are sealed. However, in actuality, only one of these sealing portions is sealed. For example, when the slot machine 10 is manufactured, the second sealing portion is sealed when the main board 273 is accommodated in the board box (case bodies 271 and 272). After that, when the main controller 131 is recovered for inspection or the like, the second sealing portion is opened, and the third sealing portion is sealed after inspection or the like.

  On the other hand, as shown in FIG. 9 and the like, on the left side portion of the main board unit 200, the movable base plate 212 and the front surface of the seal case surrounded by the surrounding frames 331 and 332 of the front case body 271 are connected to the movable base plate 212 and the front surface. A rectangular seal seal S is pasted so as to straddle the case body 271. When the seal seal S is once applied and then peeled off, the adhesive is peeled off from the seal label and cannot be applied again. When the seal seal S is peeled off, the trace remains, so the movable base It can be confirmed whether or not the main controller 131 has been removed from the plate 212. In the illustrated state where the seal seal S is affixed, the locking hole portion 247 and the through hole 248 formed in the movable base plate 212 are covered.

  As described above, the seal seal S has a configuration that cannot be re-applied. However, there is an illegal act of attaching another seal member after the seal seal S is peeled off. It is considered that one measure is to suppress the peeling action of the seal S. Therefore, in the present embodiment, as a measure for removing the seal, the seal application 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 periphery of the seal application surface is curved. It is formed in a shape. Specifically, the sealing surface is curved by forming a tapered surface in accordance with the long side portion of the seal seal S.

  When the seal seal S is affixed to the seal application surface, the peripheral portion of the seal seal S enters the curved portion of the seal application surface, and it becomes difficult to hook the peripheral portion of the seal seal S with a nail or the like. Therefore, the deterrent effect with respect to illegally peeling off the seal 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. And a key member K1 such as a padlock is attached through the key insertion portions 261a and 316a of the respective key fittings 261 and 316. Further, when the fixed base plate 211 and the movable base plate 212 are overlapped, the key mounting bracket 219 provided on the fixed base plate 211 and the 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 unlocking 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 it is the owner of the properly managed unlocking key.

  Each of the sealing portions described above is originally configured to be capable of being cut (destroyed), and the main purpose is to leave an opening history. Therefore, it is possible to prevent illegal acts such as taking away (stealing) the main controller 131. Although the effect cannot be exhibited, the above-described configuration in which the key members K1 and K2 are attached can exert a deterrent effect against the main controller 131 being taken away (can be an anti-theft measure for the main controller 131).

  Note that the tip ends of the key fittings 219 and 305 are inclined so as to escape from the main controller 131. Thereby, even if the key member K2 is attached to the side of 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. 23B shows a movable base plate with respect to the fixed base plate 211. FIG. 4C 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 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 of (a), the fixed base plate 211 and the movable base plate 212 are overlapped, and the locking claw portion 218 of the fixed base plate 211 is in the main controller 131 (actually, the front case body 271). It is latched on the top surface. 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 a surface portion facing the front side of the slot machine 10, and the main substrate surface, that is, a mounting surface such as an IC chip is visually recognized from the front.

  When the movable base plate 212 is rotated as shown in (b), the key member (at least the key member K2 in FIG. 22) is removed, and the locking claw portion 218 of the fixed base plate 211 is unlocked. In this state, the movable base plate 212 is rotated with respect to the fixed base plate 211 as illustrated. At this time, the movable base plate 212 is rotated about 90 degrees at the maximum with the support pin 217 as the rotation center, and the rotating front end portion side of the main controller 131 is pulled toward the front side together with the movable base plate 212. In such a state, it is possible to visually recognize the back side of the main control device 131 (that is, the back side of the main board 273), and it is possible to check whether there are any abnormalities or frauds in various electronic components, electrical 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 (b), the main control device 131 is viewed from an oblique side from a state of being viewed from the front side. Transition to the state. Therefore, even if it is information 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, it is easy to visually recognize by turning the movable base plate 212. It can be. For example, in the vertical IC chip 274 mounted on the main substrate 273, information such as manufacturer and product number printed on the side surface of the chip can be easily visually confirmed.

  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 problem in the rotation operation of the movable base plate 212 to the front side. It does not occur. Even if a device or mechanism that protrudes rearward of the slot machine is provided on the back surface of the front door 12, the front space of the main control device 131 is opened with the opening of the front door 12, and the movable base plate 212 is also rotated. Will not cause any problems.

  Further, when the main controller 131 shown in FIG. 23C slides, the key member (key member K1 in FIG. 22) is removed and the first sealing portion (the seal between the movable base plate 212 and the front case body 271) is removed. ) Is opened. Further, locking of the locking claw 295 provided at the left end of the front case body 271 and screw fixing at the screw hole 296 are released. In this state, the main controller 131 is slid on the movable base plate 212. As a result, the main controller 131 can be detached from the rotating tip end side of the movable base plate 212 (substrate mounting opening 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 control device 131 is equipped with a microcomputer centering on a CPU 151 as arithmetic processing means. In addition to the power supply device 161 provided in the power supply box 121, the CPU 151 is connected to a clock circuit 154 that outputs a rectangular wave having a predetermined frequency, an input / output port 155, and the like via an internal bus. The main control device 131 functions as a main base incorporated in the slot machine 10.

  On the input side of the main controller 131, there are 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 stop switches 72, 73, 74, and a medal slot. The inserted medal detection sensor 75a for detecting a medal inserted from 75, the credit insertion detection sensors 77a, 78a, 79a for individually detecting the operations of the respective credit insertion switches 77, 78, 79, and the switching for detecting the operation of the changeover switch 80. Detection sensor 80 a, reel index sensor 55 that individually detects the rotational position (origin position) of each reel 42, payout detection sensor 91 a that detects medals paid out from the hopper device 91, and reset detection sensor that detects the operation of the reset switch 123 123a, set to 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 extending from the medal insertion slot 75 to the hopper device 91 is configured such that medals can pass in one row. The storage passage 81 is provided with a first sensor, 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 inserted medal detection sensor 75a is constituted by each of the first to third sensors. 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, the main control device 131 considers that there has been a medal clogging or fraud and makes an error. If an error occurs, an error notification is performed and an 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, both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. Only when the third sensor is turned on, both the second and third sensors are turned off, and when the time for switching to each on / off switching is within a predetermined time, it is determined that the medal has been normally taken in. Otherwise, an error is assumed. The reason for this is to prevent injustice that the medal is reciprocated in the vicinity of the inserted medal detection sensor 75a and misidentified as the medal inserted in addition to the clogging of the medal 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 board 161, a power supply unit 161 a that supplies driving power to each electronic device of the slot machine 10 including the main control device 131, the power failure monitoring circuit 161 b described above, and the like are mounted.

  The power failure monitoring circuit 161b is for monitoring the power-off state and generating a power failure signal not only at the time of power failure but also at the time of power-off by the power switch 122. For this reason, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 161a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Power outage 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 this power failure signal and executes a power failure process 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, sufficient time is secured to execute the power failure process by the main controller 131.

  On the output side of the main control device 131, each active line display section 32, 33, 34, remaining number display section 35, game number display section 36, acquired number display section 37, and each reel 42L, 42M, 42R are rotated. Stepping motors 61 (61L, 61M, 61R), a medal path switching solenoid 83 provided in the selector 84, a hopper device 91, a display control device 111, an external concentration terminal plate 171 capable of transmitting information to a hall management device (not shown), 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 these are integrated. Then, after receiving a 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 manages and manages games. In other words, the sub-base is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main base. In addition, it is good also as a structure which the display control apparatus 111 controls the various display parts 32-37.

  The CPU 151 described above stores various control programs executed by the CPU 151 and a ROM 152 storing fixed value data, and temporarily stores various data when the control program stored in the ROM 152 is executed. In addition to the RAM 153 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit, as well known, and a credit counter for counting the number of credits are known. Various counters such as are built-in. 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 subsequent figures is stored in the ROM 152 described above 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 and data can be held (backed up) even after the power of the slot machine 10 is cut off. In addition to a memory and an area for temporarily storing various data and the like, a backup area is provided.

  In the backup area, when the power is shut down due to the occurrence of a power failure or the like, the values of the stack pointer, each register, I / O, etc. when the power is shut down (including power shutdown by operating the power switch 122; the same applies hereinafter) When the power failure is resolved (including power-on by operating the power switch 122. The same applies hereinafter), the slot machine 10 is in the state before power-off based on the backup area information. It is possible to return to the state. 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 in the backup area is executed in the main process (see FIG. 28) when the power is turned on. Note that 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 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed.

  Next, each control process executed by the CPU 151 in the main controller 131 will be described with reference to the flowcharts in FIGS. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and an NMI terminal (non-maskable terminal). 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 NMI interrupt processing. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 131. In the main controller 131 that has received the power failure signal via the NMI terminal, NMI interrupt processing is executed.

  In the NMI interrupt processing, first, in step S 101, the data of the used register provided in the CPU 151 is saved in the 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. 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. With this return processing, the NMI interrupt processing ends. If the power failure flag can be set without destroying the data in the register used by the CPU 151, the saving and restoring processing to the backup area can be omitted.

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

  First, in the register saving 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 a power failure flag is set. If the power failure flag is set, the process proceeds to step S203, and a power failure process 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, other interrupt processes can be executed without interruption. Therefore, for example, during the process of transmitting various commands, during the process of reading the switch state (on / off), the process at the time of power failure is not executed by interrupting each process. It is no longer necessary to create a power failure processing program that also takes into account This simplifies the processing program for power failure processing and reduces the program capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command transmission has been completed. If the transmission has not ended, the process returns to the original process of FIG. In this way, it is determined whether or not the command transmission is completed at the initial stage of the power failure process, the transmission process is prioritized when the transmission is incomplete, and the power failure process is executed after the unit command transmission process is completed. By doing so, it is no longer necessary to construct a power failure processing program that takes into account that power failure processing is executed during command transmission. As a result, the power failure processing program can be simplified and the ROM 152 can be reduced in capacity.

  If step S301 is YES, that is, if the command transmission 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 a stop process, and 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 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, subsequent RAM access is prohibited in step S305. Thereafter, an infinite loop is entered in preparation for the power supply being completely shut down and the processing being impossible.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilization voltage (5 volts) used as the drive voltage for the control system for a time sufficient to execute the above-described NMI interrupt processing and power failure processing. It is comprised so that. 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 watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S205, an interrupt end declaration process for giving an interrupt permission to the CPU 151 itself is performed. In step S206, in order to rotate the reels 42L, 42M, and 42R, a stepping motor control process for driving the stepping motors 61L to 61R, which are the respective rotary drive motors, is performed. In step S207, sensor monitoring processing is performed to monitor the state of various sensors (see FIG. 24) connected to the input / output port 155. In step S208, timer calculation processing for subtracting the value of each counter or timer is performed. In step S209, counter processing for counting the number of medals bet and the number of payouts is performed.

  In step S210, command output processing for transmitting a command or the like to the display control apparatus 111 is performed. In step S211, a segment data setting process for setting segment data displayed on the remaining number display unit 35, the game number display unit 36, and the acquired number display unit 37 is performed. In step S212, segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and segment data display processing for displaying corresponding numbers, symbols, and the like is performed. 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 the previous step S201 is restored to the corresponding register in the CPU 151. Thereafter, in step S215, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 28 is a flowchart showing a main process in the 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, the value of the stack pointer is set in the CPU 151, and an interrupt mode that permits interrupt processing is set. Thereafter, various settings for the register group in the CPU 151, the I / O device, and the like are set. And so on.

  When these initialization processes are 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 process proceeds to step S403, and all data stored in the RAM 153 is cleared as a RAM clear process.

  After confirming that the reset switch has not been operated in step S402 or performing a RAM clear process in step S403, it is determined in step S404 whether or not a setting key has been inserted into the setting key insertion hole 124. To do. If the setting key has been 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 from the six preset setting states (“Setting 1” to “Setting 6”), internal processing corresponding to the selected setting state is executed. .

  In step S406, it is confirmed whether or not a power failure flag is set. When the power failure flag is not set, that is, when the data in the RAM 153 is cleared in the previous step S403 or step S405, the process proceeds to a normal process in step S407 to be 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 subroutine processing such as RAM clear processing in step S403 and setting change processing in step S405 is not executed at all. Therefore, the data in the RAM 153 is not rewritten at all, and the power recovery process requires confirmation processing such as whether or not the data in the RAM 153 is normal.

  For this purpose, first, in step S408, it is confirmed whether or not the RAM determination value is normal. More specifically, the checksum of the RAM 153 is checked to check whether the value is normal, that is, whether the checksum taking into account the RAM determination value is 0. If the checksum value including 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, there is a high possibility 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, interrupt processing is first prohibited and all output ports in the input / output port 155 are cleared to control all actuators connected to the input / output port 155 to an off state. Thereafter, an error display for notifying the occurrence of an error to the hall manager or the like is performed, 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 stack pointer value stored in the backup area is written to the stack pointer of the CPU 151, and the stack state before the power is shut off is written. Return to the state. Next, in step S411, a power recovery command that tells execution of power recovery processing is transmitted to the display control device 111. Thereafter, in step S412, the game state is stopped and automatic settlement setting storage processing 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 processing returns to the address before the power is shut 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 the game will be described with reference to the flowchart of FIG.

  First, in step S501, it is determined whether or not a medal is bet. If a medal is bet, it is subsequently determined in step S502 whether the start lever 71 has been operated. If both step S501 and step S502 are YES, the lottery process in step S503, the reel control process in step S504, the medal payout process in step S505, and the special game state process in step S506 are executed in order, and the process returns to step S501. On the other hand, if no medal is bet in step S501 or the start lever 71 is not operated in 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, the random number table for determination of success / failure is selected based on the current setting state of the slot machine 10, the number of medals bet, and the small / probable combination probability. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6” set using a setting key (not shown), and the random number having the lowest winning probability of the combination when “setting 1” is set. A table is selected, and when “setting 6” is selected, the random number table having the highest winning probability of the combination is selected. The number of medals bet is any one of 1 to 3, and a random number table is selected such that as the number of bets increases, the winning probability of winning combination increases. For example, the winning probability of a winning combination when three bets are higher than the winning probability of winning when a single bet is three times. In addition, there are two types of small role probabilities: a random number table with a high small role winning probability is selected when the current payout rate is lower than the predetermined expected value, and small when the current winning rate is higher than the predetermined expected value. A random number table with a low winning probability is selected.

  In step S602, a random number table selected in this way is used for lottery in light of the random numbers latched by the random number counter when the start lever 71 is operated. In step S603, it is determined whether or not any of the winning combinations has been won. If any of the winning combinations has not been won, the process is terminated. If any of the winning combinations is won, the process proceeds to step S604, where a winning flag corresponding to the winning combination is set and an effective line to be aligned is determined. 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 symbols on the predetermined effective line at the timing when the stop switches 72 to 74 are pressed are different from the symbols to be stopped on the effective line, the slip table is a predetermined symbol to be stopped. It is a table that defines how much the reel slides so as to stop on the active line.

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

  In the reel control process, first, a wait process is performed in step S701. This wait process is a process of waiting without starting the reel rotation in the current game until a predetermined time (for example, 4.1 seconds) elapses from the time when the reel rotation is started 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. Following the wait process, the reel rotation process in step S702 is performed to rotate the reels 42L, 42M, and 42R. Thereafter, the process proceeds to step S703, and it is determined whether or not any of the stop switches 72 to 74 is pressed to generate a reel stop command. If no stop command has been issued, the process advances to step S704 to determine whether or not a predetermined maximum rotation time (for example, 40 seconds) of each reel 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 rotating reels.

  On the other hand, if any 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 to perform reel stop processing. In this reel stop process, the reel corresponding to the pressed stop switch is stopped. If a winning combination is won in the winning lottery 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 arranged on a predetermined effective line as much as possible. For example, when the “watermelon” symbol is lined up on the lower line and the stop switch is pressed at the timing when the “watermelon” symbol stops on the upper line, the symbol 2 is set so that it stops on the lower line. Slide the reel as much as you can. However, since the range that can be slid is determined in advance (for example, up to four symbols), the “watermelon” symbol may not stop on the lower line depending on the timing of pressing the stop switch. Even in the forced stop process in step S705, if 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 when all three reels are rotating. In the case of the first stop command, the process proceeds to step S708, and the slip table changing process is performed. In this slide table change process, for example, it is determined whether or not a combination of combinations occurs when trying to align a combination on the selected active line, and when a combination of combinations does not occur, the process proceeds to the next step as it is. When a combination of combinations occurs, the selected effective line is changed to another effective line, and after changing to a sliding table suitable for the changed effective line, the process proceeds to the next step. Here, “combination of a combination” means that, for example, when a “watermelon” symbol is arranged on the upper line, a “cherry” symbol appears on the lower line when the “cherry” symbol appears on the lower line. Refers to cases. The slip table changing process may be performed other than when avoiding the combination of the combinations.

  On the other hand, if the current stop command is not the first stop command in step S707, the process proceeds to step S709 to determine whether the second stop command is present, 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. If it is the second stop command, the process proceeds to step S710 and a stop eye determination process is performed. In this stop eye determination process, when two reels are stopped, it is determined whether or not the two are aligned with a bonus symbol such as “7” symbol. If they are not aligned, the process proceeds to the next step as it is. When sound effects are generated from the speaker 14, the process proceeds to the next step. In the stop eye determination process, it may be determined whether another condition other than two bonus symbols is satisfied, or an effect using the auxiliary display unit 15 may be performed in addition to the sound effect.

  Then, after the forced stop process in step S705, after the slip table change process in step S708, when the current stop command is not the second stop command in step S709, or the stop eye determination process in 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, and 42R have 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 then the process ends. In the payout determination process, it is determined whether or not the winning combination is arranged on the effective line. When the winning combination is not aligned on the effective line, 0 is set in the payout number storage area of the RAM 153, and the winning combination is aligned on the effective line. When it is, it is determined whether or not the winning combination matches the winning combination, and if not, an error is displayed by the upper lamp 13 or the like and 0 is set in the scheduled payout number storage area. If they match, the number of payouts corresponding to the combinations arranged in the payout amount storage area is set.

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

  In the medal payout process, first, it is determined whether or not the payout number counted by the payout number counter in step S801 matches the planned payout number stored in the payout planned number storage area. If the number of payouts does not match the planned payout number, it is determined in step S802 whether or not the game is being performed in the credit mode. If it is in the credit mode, it is determined in step S803 whether or not the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit is not reached, the count value of the credit counter and the number of payouts are each incremented by 1 in step S804. Accordingly, the remaining number display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the game is performed in the direct mode, or when the count value of the credit counter reaches the upper limit, the medal payout rotary plate is driven in step S805 and the medal is discharged from the hopper device 91 to the medal discharge port. 17 through the medal tray 18. At this time, in step S806, the number of payouts is incremented by 1 according to 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 section 37 is incremented by one. Then, after the payout number is incremented by 1 in step S804 or step S806, the process returns to step S801 again. When the number of payouts and the planned number of payouts match in step S801, the medal payout rotating plate of the hopper device 91 is stopped in step S807, and this process is terminated. The payout number / acquired number display section 37 is reset when the start lever 71 is operated next time.

  Next, the special game 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 allowed, and is a game with a very high probability that the JAC symbols (replay symbols in this case) are aligned on the active line, that is, the probability of establishment of the JAC symbols. When a JAC symbol is established in a JAC game, the maximum number (15 in this case) of medals is paid out. When the JAC symbol is established 8 times, the RB game is ended even before the JAC game reaches 12 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 (“Bell” symbols etc. are on the active line), and JAC in means entering the JAC game 12 times. When JAC symbols are aligned on the active line, JAC in is established. The JAC game is the same as that of the RB game. Also, when the JAC game by the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and before the JAC in reaches 3 times after the 30 small role games are finished. Even if there is, the BB game ends.

  In the special game state process, first, in step S901, it is determined whether or not the game state is a bonus game. If it is not during the bonus game, the process proceeds to step S902, and bonus symbol determination processing 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 is set. If it is set, the process proceeds to step S1002, and the RB symbol on the current active line is determined. It is determined whether or not (for example, “BAR” symbols) are aligned, and if the RB symbols are not aligned, this processing is terminated. On the other hand, when the RB symbols are aligned on the active line this time, in step S1003, the RB winning flag is reset and the RB setting flag is set to make an RB game which is one type of bonus game, and the RB game initial setting process shown in FIG. To finish this processing. If the RB winning flag is not set in step S1001, it is determined whether or not the BB winning flag is set in step S1004. If it is not set, the process is terminated. When the BB winning flag is set, the process proceeds to step S1005, where it is determined whether or not the BB symbol (for example, symbol “7”) is aligned on the current effective line, and when the BB symbol is not aligned, this processing is terminated. . On the other hand, when the BB symbols are aligned on the active line this time, in step S1006, the BB winning flag is reset and the BB setting flag is set to set the BB game as one type of bonus game, and the BB game initial setting process shown in FIG. Execute this to finish this process.

  35 and 36, the remaining small role game counter represents the remaining number of small role games (also referred to as the remaining small role game number), and the remaining JAC in counter represents the remaining number of remaining JAC in (remaining JAC in number). The remaining JAC establishment counter represents the remaining number of times that the JAC symbol can be established (also referred to as the number of remaining JAC formations), and the remaining JAC game counter represents the number of remaining JAC games (also referred to as the number of remaining JAC games). Represent. The number of remaining small role games, the number of remaining JAC ins, the number of remaining JACs established, and the number of remaining JAC games are displayed on the game number display unit 36 as appropriate. By the way, if a small role winning flag or replay winning flag is set by winning a small role or replay in the role lottery, those winning flags will not be aligned on the active line in the game. Will be reset, but if the RB winning flag or the BB winning flag is set by winning the RB or BB in the winning lottery, even if the RB symbol or BB symbol cannot be aligned on the active line in the game The winning flag will be carried over to the next time. In the lottery process in the next game that carries over the BB or RB winning flag, a lottery regarding whether or not a small role or replay is won is performed, but a lottery regarding BB or RB is not performed. In addition, when a small combination or replay is won in a state where the BB or RB winning flag is carried over, a slide table is stored so that the small combination or replay is preferentially aligned.

  Now, returning to FIG. 33, if the gaming state is a 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 the BB game is in the small role game, so the process proceeds to step S904, and it is determined whether or not the JAC symbols are aligned on the active line. When the JAC symbols are aligned on the active line, the JAC game is started in step S905 and the JAC game initial setting process during the BB game shown in FIG. 36B is performed, and this process is terminated. On the other hand, when the JAC symbols are not aligned on the active line in step S904, the small role game has been consumed, so in step S906 the remaining small role game number is decremented by 1, and in step S907. It is determined whether or not the number of remaining small role games has become zero. When the remaining small role game number is not 0, the present process is terminated. When the remaining small role game number is 0, the process proceeds to step S908, and a special game state end process for appropriately resetting various setting flags, BB setting flags, various counters, etc. or performing an ending process. To end this process.

  When the gaming state is a JAC game in step S903, the process proceeds to step S909 to determine whether or not the JAC symbols are aligned on the active line. When the JAC symbols are aligned on the active line, the number of remaining JACs established is determined in step S910. Decrement by one. After that, or when the JAC symbols are not aligned on the active line in step S909, one JAC game has been consumed, so the number of remaining JAC games is decremented by 1 in step S911. Subsequently, in step S912, it is determined whether or not any of the remaining number of JACs or the number of remaining JAC games has become 0. If neither is 0, that is, the JAC symbol has not yet been established 8 times. If the JAC game has not been digested 12 times, the process is terminated as it is. On the other hand, if any of them is 0, that is, if the JAC symbol is established 8 times or the JAC game is digested 12 times, the JAC in is digested once, so in step S913 the remaining JAC in The number of times is decremented by 1, and in the subsequent step S914, it is determined whether or not the number of remaining JAC in is zero. When it is 0, the special gaming state termination process of step S908 described above is performed, and this process is terminated. Incidentally, if the bonus game is an RB bonus, the initial remaining JAC in number is 1 (see FIG. 35), so it becomes 0 in step S913, and an affirmative determination is made in step S914, and the special game in step S908 The RB setting flag is reset in the state end process.

  On the other hand, when the number of remaining JAC ins is not zero in step S914, that is, when the JAC in has not been digested three times in the BB game, after performing the JAC game end processing for resetting the JAC game setting flag in step S915, When the player enters the game, one of the small role games is digested, so the number of remaining small role games is decremented by 1 in step S906, and then whether or not the remaining small role game number has become 0 in step S907. If it is determined that the number of remaining small role games is 0, the special game state ending process in step S908 described above is performed, and this process is ended. On the other hand, when the remaining small-combination game number is not 0, the small-combination game in the BB bonus has not reached 30 times and the JAC in has not reached 3 times.

  According to the embodiment described in detail above, the following excellent effects are 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 can be rotated with respect to the fixed base plate 211. The back surface (main substrate back surface) of the control device 131 is opened. Therefore, it is possible to confirm whether there are any abnormalities or frauds in various electronic components, electrical wiring, etc. on the back side. Further, when the movable base plate 212 is rotated, 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 controller 131, and It is possible to confirm that the element is genuine. As a result, it can be confirmed that the main control device 131 is not cheating, and the main control device 131 can be properly managed.

  In addition to the vertical element, when an electronic component is mounted parallel to the surface of the board, another illegal electronic component (illegal IC) is attached to the lower side of the electronic component (that is, between the electronic component and the board). However, since the movable base plate 212 on which the main controller 131 is mounted can be rotated with respect to the fixed base plate 211 as described above, it is possible to implement countermeasures against such illegal acts. In other words, it is difficult to find an unauthorized IC hidden under a legitimate electronic component just by looking at the front side of the main control device 131 from the front. Can be easily found.

  As an effect of attaching the main board unit 200 to the back plate 11c of the inner peripheral surface of the housing 11, the main control device 131 remains attached while the main control device 131 is not easily removed. Since the distance between the main control device 131 and the front open portion of the housing 11 is long, unauthorized signal lines are connected to the main control device 131 through the front open portion of the housing 11. It is difficult to cheat, when the front door 12 is released, the main controller 131 can be seen in the front, so it is easy to find fraud on the surface of the board. Since the lateral width is larger than the side plates 11d and 11e, a relatively large controller can be installed. Etc. are obtained.

  The main controller 131 is configured to be detachable from the rotating front end side of the movable base plate 212 by sliding the main controller 131 on the movable base plate 212 in a state where the movable base plate 212 is rotated. Therefore, the main control device 131 can be easily attached or detached with the rotating tip of the movable base plate 212 being pulled toward the near side. Therefore, workability at the time of inspection or replacement of the main controller 131 can be improved.

  Since the fixed base plate 211 is fastened from the outside of the housing by using the screws 233 across the back plate 11c of the housing 11, for example, in a state where many slot machines 10 are installed in the game hall, the fixed base plate 211 As a result, unauthorized removal of the main controller 131 can be suppressed. Thereby, not only the main control device 131 but also the pedestal device 210 can be prevented from being illegally taken away (stolen).

  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 attached to either the left or right side plate 11d, 11e of the housing 11. It is good also as a structure attached to. Even if it is attached to any of the left and right side plates 11d and 11e of the housing 11, the rotation of the rotation base plate 112 with respect to the fixed base plate 211 allows the main control device 131 to be moved to the front side (that is, the slot machine). 10 forward), and as described above, excellent effects can be obtained.

  (B) In the above embodiment, the fixed base plate 211 and the movable base plate 212 are pivotally connected using the support pins 217 press-fitted into the shaft holes. However, this configuration is changed. For example, a structure in which a support column is integrally formed with 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 column may be employed. Any configuration can be applied as long as each of the base plates 211 and 212 is rotatable and cannot be separated (cannot be disconnected).

  (C) In the above embodiment, in the main board unit 200, the fixed base plate 211 and the movable base plate 212 are set to have approximately the same size in accordance with 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 controller 131 can be considered. 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, the movable base plate 212 may be configured to be rotated so that the back surface of the main controller 131 can be easily confirmed. The fixed base plate 211 may also be made smaller or larger than the main control device 131 on the assumption that the main control device 131 can be securely attached.

  (D) In the above embodiment, the shaft support portion is provided on the short side portion of the fixed base plate 211, but the shaft support portion may be provided on the long side portion of the fixed base plate 211. In this case, the amount of pulling of the movable base plate 212 toward the front side is reduced, but the facing angle of the main controller 131 when viewed from the front of the slot machine is the same, and the confirmation of the main board 273 is still preferable. It can be implemented (the same applies to reading side information of the IC chip 274).

  (E) In the above embodiment, the fixed base plate 211 and the movable base plate 212 constituting the base member 210 are both formed of a transparent synthetic resin material. However, the fixed base plate 211 is 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. Further, since 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 viewing window on the bottom plate portion 241 of the movable base plate 212 is added, the movable base plate 212 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.

  (F) In the above embodiment, in order to guide the main control device 131 in the sliding direction on the movable base plate 212 and to hold the main control device 131 integrally, the return portion over the entire longitudinal direction of the side plate portions 242 and 243. Although 242a and 243a are provided (see FIG. 12), part of the return portions 242a and 243a near the board mounting opening 245 may be removed. For example, in the configuration of FIG. 12, the two return portions 242a and 243a from the right are removed. By removing a part of the return portions 242a and 243a, the required slide amount of the main control device 131 on the movable base plate 212 is reduced, and the main control device 131 can be easily attached and detached.

  (G) The second base member (movable base plate 212) may be configured to be double-opened so that it can be rotated (opened) to the left and right sides. Specifically, a rotation shaft portion is provided on each of the left and right end portions of the fixed base plate 211 so that the movable base plate 212 can be rotated in two directions opposite to each other around each rotation shaft portion. As a result, it is possible to draw the one desired by the operator or the like at the left and right ends of the main control device 131 (control board device) to the near side.

  (H) The second base member (movable base plate 212) is mounted with a rotation base that is rotatably connected to the first base member (fixed base plate 211), and a control board device (main control device 131). It is good also as a structure which comprises a board | substrate mounting part and connects a board | substrate mounting part so that front and back inversion is possible with respect to a rotation base. According to this configuration, the casing-facing surface of the control board device can be easily confirmed by rotating the rotating base with respect to the first base member and further inverting the board mounting portion with respect to the rotating base. become able to.

  (I) In the above embodiment, in the main substrate unit 200, the movable base plate 212 is provided so as to be rotatable with respect to the fixed base plate 211. However, this configuration is changed as follows. For example, a leg portion (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 shrinking the leg portion. In this state, the movable base plate 212 is moved away from the fixed base plate 211 by extending the legs so that the main controller 131 is pulled toward the near side. In this case, the movable base plate 212 can be moved so as to move in parallel with the fixed base plate 211. In addition, two left and right leg portions are provided between the fixed base plate 211 and the movable base plate 212, and the leg portions are independently expanded and contracted. According to this configuration, the main control device 131 can be pulled in a state where the main control device 131 is inclined 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. As a result, it is possible to easily confirm whether or not there is an illegal act 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.

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

  (L) The structure concerning the sealing part of the main controller 131 can be changed elsewhere. The place where the sealing portion is provided may be provided on the long side portion of the substrate box (case bodies 271 and 272) in addition to the left and right short side portions of the substrate box (case bodies 271 and 272). Moreover, it may replace with the structure which uses a sealing screw, and the structure etc. which insert a sealing metal fitting piece in a sealing connection part may be sufficient.

  (M) In the above embodiment, in order to fix and attach the fixed base plate 211 to the back plate 11c of the housing 11, the fastening is performed with the two screws 223 from the inside of the housing and the center from the outside of the housing. Although it is set as the structure which fastens with the screw 233 of one place, this structure is changed. For example, the fixed base plate 211 may be fastened only from the outside of the housing. In such a case, two or more fastening locations (specifically, installation locations of the fixing bracket 225) may be used.

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

  (O) In the above embodiment, the pedestal device 210 is constituted by two pedestal members (the fixed base plate 211 and the movable base plate 212), and the main controller 131 is placed on one of the pedestal members (the movable base plate 212). However, this is changed as follows. The pedestal device is constituted by a single pedestal member, and the pedestal member is fixed to the back plate 11 c of the housing 11. The main controller is connected to the base member so as to be rotatable (or displaceable). Even in this configuration, it is still possible to easily check the back surface (housing facing surface) of the main control device.
