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.

  As shown in FIG. 6, these reels 42L, 42M, and 42R are connected to stepping motors 61L, 61M, and 61R, respectively, and driven by the stepping motors 61L, 61M, and 61R, the reels 42L, 42M, and 42R, respectively. Are configured to be able to rotate individually, that is, independently of each other. Since these reels 42L, 42M, and 42R have the same configuration, the left reel 42L is depicted as a representative of each reel in FIG.

  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 rotating shaft 62 of the left reel stepping motor 61L via a disk-like boss reinforcing plate 52. Specifically, the boss portion 51 of the cylindrical skeleton member 50 is fixed to a boss reinforcing plate 52 as a connecting portion by a screw 57 that is a fixture. Further, as shown in FIG. 7, the boss reinforcing plate 52 is fixed to the rotating shaft 62 of the stepping motor 61 </ b> L by a screw 64. Accordingly, when the drive shaft of the stepping motor 61L for the left reel rotates, the cylindrical skeleton member 50 is rotated around the rotation shaft so that the left reel 42L circulates along the annular reel surface. It has become.

  As shown in FIG. 6, the left reel stepping motor 61 </ b> L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) by 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, The rotational position of the left 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. 8 shows a symbol array 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). In the belts wound around the reels 42L, 42M, and 42R, the number and arrangement order of various symbols are completely different.

  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.

  Further, in the present embodiment, the backlight devices 100L, 100M, and 100R that illuminate the belts of the reels 42L, 42M, and 42R from the inside are provided on the inner side surfaces of the reels 42L, 42M, and 42R as shown in FIG. 10 and is fixed to the motor plate 53 with screws 106 as shown in FIG.

The apparatus 100M includes a right backlight apparatus 100R. As described above, the backlight devices 100L, 100M, and 100R are arranged on the side surfaces of the motor plates 53L, 53M, and 53R arranged in correspondence with the reels 42L, 42M, and 42R in the reel unit 41, respectively. Is attached to the side. And each backlight apparatus 100L, 100M, 100R is arrange | positioned in the same position seeing to an up-down direction. FIG. 9A is an enlarged perspective view showing the periphery of the reel unit 41 in a state where the reels 42L, 42M, and 42R are removed. Further, FIG. 9B used in the following description is a front view of the left backlight device 100L. In FIG. 9B, since the backlight devices 100L, 100M, and 100R all have the same structure, the left backlight device 100L is representatively illustrated.

  As shown in FIG. 9B, the left backlight device 100L has a box shape with the front side opened, and the length in the vertical direction and the length in the horizontal direction are substantially the same as the display window 31L (FIG. 1). A base 101L is provided. In the base 101L, two partition walls that divide the opening area are formed vertically at equal intervals, so that the first opening area 102L, the second opening area 103L, and the third opening area 104L are arranged in the upper, middle, and lower stages. It has a configuration. When the front door 12 is closed, the opening regions 102L, 103L, and 104L are located behind the positions corresponding to the upper, middle, and lower stages of the display window 31L, respectively. Specifically, the first opening area 102L is located behind the upper stage of the display window 31L, the second opening area 103L is located behind the middle stage of the display window 31L, and the third opening area 104L is the display window 31L. Located behind the lower tier. In addition, the opening front of the first opening region 102L is slightly upward, and the opening front of the third opening region 104L is slightly downward. Accordingly, the side surface of the base 101L has an arc shape that bulges toward the game panel 30 side.

  In each of the opening regions 102L, 103L, and 104L, four backlights 105 each made of a light emitting diode are disposed so as to stand forward. Two backlights 105 in each of the opening regions 102L, 103L, and 104L are arranged in two upper and lower rows with a predetermined interval, and the backlights 105 in each row are horizontal with a predetermined interval. Are lined up like That is, the left backlight device 100L includes a first line L1 that is an upper row of the first opening region 102L, a second line L2 that is a lower row, and a third line that is a row above the second opening region 103L. L3 and the fourth line L4, which is the lower row, the fifth line L5, which is the upper row of the third opening region 104L, and the sixth line L6, which is the lower row, total 6 in the vertical direction across the partition wall. There will be a line of backlight 105 in the column. The middle backlight device 100M and the right backlight device 100R also have a total of six lines of the backlight 105. As described above, the backlight devices 100L, 100M, and 100R are viewed in the vertical direction. Since they are arranged at the same position, the lines L1 to L6 of the backlight devices 100L, 100M, and 100R are located on the same line. That is, the line L1 is a line that horizontally connects a total of six backlights 105 arranged in a row above the first opening regions 102L, 102M, and 102R of the backlight devices 100L, 100M, and 100R. Become. The same applies to the other lines L2 to L6. Each backlight 105 is controlled for each of the lines L1 to L6. Accordingly, the backlight 105 is turned on and off for each of the lines L1 to L6.

  When the backlights 105 on the lines L1 to L6 are turned on, different positions of the belts of the reels 42L, 42M, and 42R are illuminated in red from the rear. As described above, each of the bases 101L, 101M, and 101R is divided into three opening regions 102 to 104 by the partition walls. Therefore, when the backlights 105 on the first line L1 and the second line L2 are turned on, only the inner surface of the belt near the position corresponding to the upper stage of the display windows 31L, 31M, 31R is illuminated, and the display window 31L , 31M, 31R, the inner surface of the belt near the positions corresponding to the middle and lower stages is not illuminated. This is the same when the backlight 105 on the other lines L3 to L6 is turned on. As described above, since the belt is made of a material that can transmit the irradiated light to some extent, when the belt is illuminated from the rear by the backlight 105, the light transmitted through the belt is displayed on the display windows 31L, It is visually recognized by the player through 31M and 31R. As a result, the player can visually recognize that the outer surface of the belt where the light is irradiated is red, and the pattern attached to the portion where the light of the belt is irradiated can be changed. It can be emphasized more than the symbol attached to the part. For example, when the backlight 105 on the line L1 and the line L2 is turned on, the belt in the vicinity of the position corresponding to the upper stage of the display windows 31L, 31M, and 31R becomes red, and the upper part of the display windows 31L, 31M, and 31R is supported. The pattern attached to the belt near the position can be emphasized. Further, when the reels 42L, 42M, and 42R are rotating, the symbols attached to the belt passing in front of the lit backlight 105 are emphasized. Note that the backlights 105 of the backlight devices 100L, 100M, and 100R are turned on in a predetermined pattern when synchronization fluctuation described later is performed, and are basically turned off when the synchronization fluctuation is not performed. As a light source for illuminating the symbols attached to the belts of the reels 42L, 42M, and 42R while this synchronous variation is not performed, a front light (not shown) is on the rear side of the front door 12 and the display windows 31L, 31M, and 31R. It is arrange | positioned above.

  As shown in FIG. 1, the game panel 30 is connected to each display window 31L, 31M, 31R, three in parallel in the horizontal direction, and two in the diagonal direction. Is attached. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to 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. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. A winning is awarded when the symbols are stopped in a predetermined combination on the activated combination line, that is, on the activated line, 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, as shown in FIG. 1, 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. Further, if attention is paid to the point that the medal insertion slot 75 is accompanied by the operation of directly inserting the 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.

  As shown in FIGS. 3 and 4, the medal inserted from the medal slot 75 is guided to either the storage passage 81 or the discharge passage 82 by the selector 83 provided on the back surface of the front door 12. The selector 83 is provided with a medal passage switching member 84 to be described later, so that the medal passage direction is switched between the discharge passage 82 side and the storage passage 81 side according to the state of the medal passage switching member 84. It has become. The medal guided to the storage passage 81 is guided to the hopper device 91 housed in the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  FIG. 12 is a diagram illustrating the internal structure of the selector 83. The two-dot chain line in the figure indicates the medal passage route for easy understanding. The selector 83 is formed with a guide passage 85 for guiding medals inserted from the medal insertion port 75 to the storage passage 81. The guide passage 85 is formed in a curved line that draws an arc from the upper end to the lower right in the drawing so that medals can pass in one row. More specifically, the selector body constituting the selector 83 is provided with a ridge 85a protruding toward the front side of the figure, and a guide passage 85 is formed along the ridge 85a. Thereby, the medal that has reached the guide passage 85 flows in the downstream direction so as to roll on the ridge 85a.

  The medal passage switching member 84 includes a passage switching piece 84a that is provided upstream of the guide passage 85 and can be moved in and out of the guide passage 85, and a solenoid (not shown) for operating the passage switching piece 84a. is doing. When the solenoid is not excited, the passage switching piece 84a protrudes into the guide passage 85, and the flow of medals to the storage passage 81 is obstructed. As a result, the medal falls downward so as to get over the protrusion 85 a and is guided to the discharge passage 82. Further, the passage switching piece 84a is sunk outside the guide passage 85 when the solenoid is excited. Thereby, the medal flows along the guide passage 85 and is guided to the storage passage 81.

  A first inserted medal detection sensor 86 for detecting the passage of medals and a second inserted medal detection sensor 87 are arranged close to each other on the downstream side of the passage switching piece 84a so as to be arranged upstream and downstream of the guide passage 85. (At least one time is set to a close state where the same medal is detected at the same time). When the solenoid of the medal path switching member 84 is not energized, the medal falls downward from the middle of the guide path 84, so that the inserted medal detection sensors 86 and 87 do not detect the passage of the medal. On the other hand, at the time of solenoid excitation of the medal path switching member 84, the passage of medals is sequentially detected by the inserted medal detection sensors 86 and 87.

  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. The medal guided to the storage passage 81 is guided to the hopper device 91 housed in the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  As shown in FIGS. 3 and 5, the hopper device 91 as a payout means for giving a medal to a player includes a storage tank 92 for storing the medal and a payout device 93 for paying out the medal to the player. Yes. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95.

  A button-like return switch 76 (FIG. 1) is provided below the medal slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal slot 75 is jammed in the selector 84. When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, 31R, as shown in FIG. 1, a button-shaped first credit insertion switch 77 is provided for inserting three credited virtual medals as investment values at a time. ing. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. Each of the credit insertion switches 77 to 79, together with the medal insertion slot 75, constitutes an input means for inputting an investment value. Further, if the medal insertion slot 75 is accompanied by an operation of directly inserting a medal by the player, each credit insertion switch 77 to 79 is only accompanied by an operation of inserting a virtual medal based on the storage memory. It can also be said that it constitutes an indirect input means for indirectly inputting the investment value.

  The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) to urge that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77. However, when there is no credited virtual medal or three medals have already been inserted. It is turned off under the circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  A button-like changeover switch 80 is provided on the left side of the start lever 71. The change-over switch 80 is configured to be a toggle type that is turned on when pressed once, turned off when pressed again, and turned on / off every time the pressing operation is performed. The changeover switch 80 is operated to change the handling format of inserted medals inserted into the medal slot 75 more than necessary, or acquired medals returned to the player as a result of a predetermined game.

  When the change-over switch 80 is in the ON state, the “credit mode” is set so that surplus inserted medals up to a predetermined maximum value (for example, 50 medals) and winning medals are stored and stored as credit medals. " When the changeover switch 80 is in the OFF state, the “direct mode” is set so that surplus inserted medals and winning medals are paid out as actual medals. If there is a credit medal when the credit mode is switched to the direct mode, the corresponding credit medal is paid out as an actual medal. Thus, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for changing over the input value and game value handling formats. Further, if paying attention to the function of paying out a credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored game value. In addition to being configured to switch between the “credit mode” and the “direct mode” by operating the changeover switch 80, the virtual medal stored and stored is paid out when the changeover switch 80 is operated by always setting the “credit mode”. It may be made to function as only a settlement switch.

  Below the display windows 31L, 31M, 31R of the gaming panel 30, there are a remaining number display section 35 for displaying the number of medals activated and stored in the credit mode, and in a special gaming state such as a big bonus or a regular bonus. For example, a game number display unit 36 for displaying the number of remaining games and an acquired number display unit 37 for displaying the number of acquired medals are provided. Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, a procedure for betting medals will be described. In both the direct mode and the credit mode, a bet is placed when a medal is inserted from the medal slot 75 at the start of the game.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display section 32 is turned on, and the corresponding center line becomes the effective line, and the second medal is the medal insertion slot. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including the upper line and the lower line corresponding to the second effective line display section 33 become effective lines, respectively, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further turned on, and a total of five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal slot 75, the surplus medals exceeding three are switched to the discharge passage 82 by the selector 84 if the current mode is the direct mode. It is returned from the outlet 17 to the medal tray 18. On the other hand, in the credit mode, it is stored inside the slot machine, and the number of stored sheets is displayed on the remaining number display unit 35. An upper limit number is determined for the number of stored sheets (for example, 50), and when a medal exceeding the number is inserted, it is returned from the medal discharge port 17 to the medal tray 18.

  In addition, when a game is played in the credit mode and the number of stored items is displayed on the remaining number display unit 35, the virtual number is displayed even when any of the first to third credit insertion switches 77 to 79 is pressed. A medal is inserted and a bet is placed.

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the remaining number display section 35 is decremented by one as a virtual medal is inserted, and the first effective line display section 32 is displayed. Illuminates and the center line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the remaining number display unit 35 are decremented as two virtual medals are inserted, and the first valid line display unit 32 and The second effective line display section 33 is lit and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the remaining number display unit 35 are decremented as three virtual medals are inserted, and all the effective line display units 32 to 32 are decremented. 34 lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed is not stored, for example, when the display of the remaining number display unit 35 is 2, the first For example, when the credit insertion switch 77 is pressed, all the values in the remaining number display section 35 are decremented to 0, and a bet is made for the amount of virtual medals that can be inserted.

  On the upper part of the front door 12, there are an upper lamp 13 that lights up or flashes as the game progresses, and a pair of left and right sounds that make various sound effects as the game progresses and inform the player of the game state Speaker 14 and an auxiliary display unit 15 for giving various information to the player. In the present embodiment, the auxiliary display unit 15 is configured by a liquid crystal display for the purpose of diversifying display contents and increasing the display effect. However, other displays such as a dot matrix display may be used. Good. The auxiliary display unit 15 is for executing various display effects as the game progresses, and it can be considered that the game by the reels 42L, 42M, and 42R is caused by the main display unit. This is referred to as an auxiliary display unit 15. On the back surface of the auxiliary display unit 15, an upper lamp 13, a speaker 14, and a display control device 111 for driving the auxiliary display unit 15 are provided. The positions and numbers of the upper lamp 13 and the speakers 14 are not limited to those described above.

  A lower plate 16 on which a model name, a character related to a game, and the like are displayed is mounted above the medal tray 18. In addition, an ashtray 19 that can be reversed to the lower side on the front side is provided on the left side of the medal tray 18.

  A power supply box 121 is provided on the left side of the hopper device 91 inside the housing 11. The power supply box 121 includes a power switch 122, a reset switch 123, a setting key insertion hole 124, and the like. The power switch 122 is a start switch for supplying power to each unit including the main controller 131.

  The reset switch 123 is a switch for resetting various states of the slot machine 10. This slot machine 10 has a backup function for various data, and even if a power failure occurs, it retains the state at the time of the power failure and returns to the state at the time of the power failure at the time of recovery from power failure (power recovery). It can be done. Therefore, for example, when the power supply is shut down by a normal procedure, such as when the game hall is closed, the state before the power shut-off is stored, but if the power switch 122 is turned on while pressing the reset switch 123, the backup data is reset. It has become so. If the reset switch 123 is pressed while the power switch 122 is on, the error state is reset.

  The setting key insertion hole 124 is used by a hole manager or the like to adjust the appearance of medals. That is, the setting state (winning probability setting process) of the slot machine 10 can be changed from “setting 1” to “setting 6” by operating the hole manager or the like by inserting the setting key into the setting key insertion hole 124. It has become.

  As shown in FIG. 5, a main control device 131 is attached to the back plate 11 c of the housing 11 above the reel unit 41. The main control device 131 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of planning is provided, and the main board is accommodated in a board box as an encapsulating means made of a transparent resin material or the like.

  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 board built 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. 75, an inserted medal detection sensor 75a for detecting a medal inserted from 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operations of the respective credit insertion switches 77, 78, 79, and switching for detecting an 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. When 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, by providing a sub-base for voice, lamps, and display related to indirect games, the burden on the main base is reduced. 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. 20 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 cut off by the power failure process (see FIG. 22), and the restoration of each value written in the backup area is executed in the main process (see FIG. 23) 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 of 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. 20 is a flowchart illustrating an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 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. 21 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 for monitoring the state of various sensors (see FIG. 19) connected to the input / output port 155 is performed. 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. 23 is a flowchart showing a main process in main controller 131 executed after power-on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, 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. Etc.

  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 based on 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 in 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. 29, 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 effective 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 obtain a BB game which is a kind of bonus game, and the BB game shown in FIG. The initial setting process is executed and this process is terminated.

  30 and 31, 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). To express. 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 appropriately displayed on the game number display unit 36. 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. 28, 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. 31B 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. 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. 30), so it becomes 0 in step S913, and an affirmative determination is always 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.

  Here, the attachment structure of each reel 42L, 42M, 42R to the stepping motors 61L, 61M, 61R will be described again.

  As described above with reference to FIGS. 6 and 7, the boss reinforcing plate 52 as a connecting portion is fixed to the rotating shaft 62 of the stepping motors 61 </ b> L, 61 </ b> M, 61 </ b> R with screws 64. Each boss portion 51 of the cylindrical skeleton member 50 of each reel 42L, 42M, 42R is fixed to the boss reinforcing plate 52 with a screw 57 as a fixing tool. The boss reinforcing plate 52 is made of metal, and the cylindrical skeleton member 50 is made of resin.

  Each boss 51 of each reel 42L, 42M, 42R is formed with a shaft hole 63 through which the rotation shaft 62 of the stepping motors 61L, 61M, 61R is inserted, as shown in FIGS. Screw holes 58, 58, 58 through which the screws 57, 57, 57 are inserted are formed. The screw holes 58, 58, 58 are formed on the same circumference C around the shaft hole 63, in other words, around the rotation shaft 62. Further, a plurality of cutout holes 59,... 59 are formed around each screw hole 58. This cut-out hole 59 is a long hole extending in the circumferential direction of a virtual circle centered on the screw hole 58, and the circumferential length L is based on the mutual distance D between the adjacent cut-out holes 59, 59. long. In other words, the distance D between the adjacent cutout holes 59 is shorter than the circumferential length L of the cutout hole 59.

  Further, an edge 59i on the screw hole 58 side of the cutout hole 59 (hereinafter referred to as an inner edge) and an edge far from the screw hole 58 of the cutout hole 59 (hereinafter referred to as an outer edge) 59o are shown in FIGS. As shown in FIG. 15, all of them are located farther from the outer edge of the washer 57 a inserted through the screw 57 with respect to the screw hole 58.

  As described above, in the present embodiment, since the plurality of cutout holes 59,..., 59 are formed around the screw hole 58, they are adjacent by pulling the cylindrical skeleton member 50 in the direction P away from the motor. Stress concentrates between the cutout holes 59, 59, and cracks s there, and among the portions where the boss portion 51 is formed, the inner portion on the screw hole 58 side with respect to the plurality of cutout holes 59, The outer part is separated. That is, in this embodiment, it is possible to easily separate most of the resin reel 42 from the stepping motor 61 without using the tool to remove the three screws 57. For this reason, the trouble at the time of recycling the resin reel 42 can be saved.

  By the way, as shown in FIG. 14, the space between the cutout holes 59, 59 of the screw holes 58, 58, 58 exists on the circumference C where the screw holes 58, 58, 58 are located. . As described above, since each of the cutout holes 59 and 59 exists on the circumference C, the sudden stop from the state where the reel 42 is rotating and the rotation from the stopped state are repeated. Even if a load is repeatedly applied in the direction of the circumference C, the cutout hole 59 does not exist on the circumference C, and there is a portion between the cutout holes 59, 59. The strength of the reel 42 can be ensured. On the other hand, in the present embodiment, although repeated, the reel 42 is easily broken by pulling in the P direction.

  In this embodiment, the inner edge 59i and the outer edge 59o of the cutout hole 59 are both positioned farther from the outer edge of the washer 57a with respect to the screw hole 58. However, the outer edge 59o of the cutout hole 59 is not limited. May be positioned farther from the outer edge of the washer 57a, and the inner edge 59i may be positioned closer to the outer edge of the washer 57a. In this case, the outer edge of the washer 57a is positioned between the cutout holes 59 and 59, and when the reel 42 is pulled in the P direction, the mutual bend is made with the outer edge of the washer 57a as a base point. Cracks are more easily formed between each other.

  Next, some modified examples related to the separation structure of the reel 42 for the material recycling described above will be described.

  First, a first modification regarding the separation structure of the reel 42 will be described with reference to FIG. Also in this modified example, a plurality of cutout holes 59, 59, 59 are formed around the screw hole 58 as in the above embodiment. A back washer 57b as a reinforcing plate is disposed between the boss portion 51 of the cylindrical skeleton member 50 and the boss reinforcing plate 52. The back washer 57b is formed with a through hole through which the screw 57 can be inserted. Further, the outer radius of the back washer 57 b is longer than the distance from the center of the screw hole 58 to the outer edge 59 o of the cutout hole 59. On the boss reinforcing plate 52 side of the boss portion 51, a rib 51r is formed that restricts the back washer 57b from moving in a direction perpendicular to the direction of penetration of the screw hole 58.

  As described above, the rear washer 57b is disposed, and the rib 51r for restricting the movement of the rear washer 57b is provided in the boss portion 51, thereby maintaining the ease of separation of the reel when the reel 42 is pulled in the P direction. On the other hand, the strength of the boss portion 51 when a load in the (−) P direction and a load perpendicular to the P direction are applied to the screw 57 can be increased. When a load in the (−) P direction is applied to the screw 57, the back washer 57b and the boss reinforcing plate 52 receive this load. For this reason, the durability of the boss portion 51 against such a load increases. Further, when a load in a direction perpendicular to the P direction is applied to the screw 57, the back washer 57b and the rib 51r receive this load. For this reason, the load applied between the cutout holes 59 is reduced, and the strength of the boss portion 51 is improved.

  The back washer 57b does not have to be on a disk, and the distance from the center of the screw hole 58 to the outer edge of the back washer is longer than the distance from the center of the screw hole 58 to the outer edge 59o of the cutout hole 59. For example, any shape such as a square or a hexagon may be used. In this modification, the rib 51r is provided on the boss 51 side, but may be provided on the boss reinforcing plate 52 side.

  Next, a second modification regarding the separation structure of the reel 42 will be described with reference to FIG. Also in this modified example, a plurality of cutout holes 59, 59, 59 are formed around the screw hole 58 as in the above embodiment. A recess 59a is formed between the adjacent cutout holes 59 and 59, and among the portions around the cutout hole 59, the thickness of the mutual portion is thinner than the thickness of the other portions. Yes.

  In the present modification, as described above, the ease of separation of the reel 42 can be enhanced by reducing the thickness between the adjacent cutout holes 59 and 59. However, the fact that the ease of separation of the reel 42 has increased means that the strength around the screw 57 has decreased, so when the recess 59a is formed between the adjacent cutout holes 59, 59, In consideration of the required strength around the screw 57, it is necessary to determine whether or not to form the recess 59a, the depth of the recess 59a, and the like.

  Thus, as a method for adjusting the ease of separation of the reel 42 and the strength around the screw, in addition to the above, the relative distance between the cutout holes 59 and 59 with respect to the length of the cutout hole 59 is changed. In addition to the method, there is a method in which a bottom surface is formed in the cutout hole 59 and the depth of the cutout hole 59 is changed.

  Next, the 3rd modification regarding the separation structure of the reel 42 is demonstrated using FIG. Also in this modified example, a plurality of cutout holes 59b, 59b, 59b are formed around the screw hole 58 as in the above embodiment. However, the cutout hole 59b of the present modified example is different from the above-described embodiment and the modified example in that acute angle portions 59c and 59c are formed at both ends on the outer edge side of the cutout hole 59b. As a result, the mutual distance between the acute angle portions 59c and 59c of the two adjacent cutout holes 59b and 59b is the shortest distance between the two cutout holes 59b and 59b.

  In the present modification, as described above, by forming the acute angle portion 59c in each cutout hole 59b, stress concentrates on the acute angle portion 59c, and cracks s are easily formed, and the reel 42 can be easily separated. Can be increased. However, as described above, the fact that the ease of separation of the reel 42 has increased means that the strength around the screw has decreased, so whether the acute angle portion 59c should be formed in consideration of the necessary strength around the screw. It is necessary to decide whether or not.

  Although the above is an example in which the reel 42 is fixed to the rotating shaft 62 of the motor 61 via the boss reinforcing plate 52, the rotating shaft 62 is directly connected without using a connecting member such as the boss reinforcing plate 52. Even when the reel 42 is fixed with a fixing tool such as a screw, the ease of separation of the reel 42 can be enhanced by the same method as described above.

  In the above description, screws are used as the fixing means. However, even when the reel 42 is fixed to the rotary shaft 62 with bolts and nuts, and further with an adhesive or the like, a cutting hole is formed around the fixing means. Thus, it goes without saying that the same effect as described above can be obtained.
