  First, invention groups that can be extracted from the present embodiment are shown as means n (n = 1, 2, 3,...), And will be described while showing effects and the like as necessary. In the following, for ease of understanding, the corresponding configuration in the present embodiment is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Means 1. Variable display means (reel unit 41) for variably displaying a pattern in a plurality of pattern rows;
Stop operation means (stop switches 72 to 74) for stopping variable display of the picture on the variable display means by the player's operation;
Lottery means (main control device 131) for lottery whether or not the internal hit state with a predetermined hit probability;
And a bonus is given to the player by causing the display picture of the variable display means to be stopped and displayed with a combination of specific pictures in accordance with the operation of the stop operation means after the lottery means has achieved an internal winning state. In a gaming machine configured as follows:
Delay means (main control device 131) for delaying the state of being able to be stopped and displayed with the combination of the specific patterns after the internal hit state has been reached;
Trigger picture display control means (main control device 131) for controlling the variable display means so as to display a combination of trigger pictures (symbol combinations A and B) that trigger the delay by the delay means;
A gaming machine characterized by comprising:

  In the gaming machine of means 1, an internal hit state is generated with a predetermined hit probability, and after the internal hit state is reached, the delay means makes it possible to stop display with a combination of specific pictures. Is delayed. At this time, by controlling the variable display means, a combination of trigger pictures that are triggers for the delay by the delay means is displayed. According to this configuration, the player confirms the display of the trigger picture combination, so that it is difficult or impossible to acquire a bonus game or the like until the delay by the delay means is activated, that is, until the delay process is completed. You can see that it is possible. Therefore, the inconvenience caused by continuing the game unnecessarily without obtaining the privilege can be avoided.

  Mean 2. In the means 1, in the state of delay by the delay means, the combination of other patterns (for example, replay symbols) can be stopped and displayed in preference to the combination of the specific patterns being stopped and displayed. A game machine characterized by causing a state in which a combination of patterns can be stopped and displayed frequently.

  According to the means 2, under the state of the delay by the delay means, the combination of the specific pattern is set in a state in which the combination of the other pattern can be stopped and displayed in preference to the stop display of the combination of the specific pattern. A state in which the combination can be stopped and displayed is frequently generated. Thereby, after it becomes an internal hit state, it will be delayed until it will be in the state which can be stopped and displayed by the combination of a specific pattern. For example, it is conceivable to shift to a replay time (RT) in which a replay game (replay) is established with a relatively high probability.

  Means 3. In the means 1 or 2, the gaming machine characterized by not performing the internal winning lottery by the lottery means or invalidating the lottery result under the state of delay by the delay means.

  According to the means 3, even if the internal winning lottery is not performed by the lottery means under the delay state by the delay means, or even if the lottery is performed, the lottery result is invalidated. Therefore, a plurality of internal hit states are not accumulated (stocked).

  Means 4. In any one of the means 1 to 3, the delay means continues the delay state with a predetermined probability.

  According to the means 4, the number of games (the number of games) until the privilege is acquired can be appropriately adjusted by continuing the delay state. Therefore, it is possible to have a hit wave (change) in the flow of the game, and it is possible to enhance the interest of the game. In this case, since how long the delay state continues is not fixed, the difficulty of predicting the game is increased, and the interest of the game can be enhanced.

  Means 5. In any one of the means 1 to 4, the delay means causes the delay state to be continued by causing the trigger picture display control means to display the trigger picture.

  According to the means 5, by confirming that the trigger picture is displayed again under the state of the delay by the delay means, it can be grasped again that the delay by the delay means is being activated.

  Means 6. In the means 5, in the state of delay by the delay means, the trigger picture display control means displays the trigger picture with a predetermined probability, and when the predetermined number of games are finished without displaying the trigger picture, the delay by the delay means A game machine characterized by ending.

  According to the means 6, the trigger picture is displayed with a predetermined probability in the state of the delay by the delay means, but when the predetermined number of games are finished without displaying the trigger picture, the delay by the delay means is delayed. Is terminated. Therefore, the delay can be canceled by continuing the state in which the opportunity pattern is not displayed.

  Mean 7 In any one of the means 1 to 6, the delay means is configured to be able to distribute a plurality of delay modes (RT modes 1 and 2) having different degrees of delay.

  According to the means 7, since the delay by the delay means is set with a plurality of delay modes having different degrees of delay, diversity can be given to the game.

  Means 8. The game machine according to claim 7, wherein the opportunity picture display control means displays a different opportunity picture for each of the plurality of delay modes.

  According to the means 8, since a different trigger picture is displayed for each of the plurality of delay modes, it is possible to grasp the delay mode for each time by checking which trigger picture is displayed.

  Means 9. In the means 7 or 8, the delay means is configured to stay in the mode with a relatively high probability after entering one of the plurality of delay modes.

  According to the means 9, for example, after entering a delay mode with a large degree of delay, the mode is stagnated with a relatively high probability. In addition, after entering a delay mode with a small degree of delay, the mode stops with a relatively high probability. A large degree of delay means that the privilege acquisition rate is low, and conversely, a small degree of delay means that the privilege acquisition rate is high. Therefore, it is possible to differentiate between a disadvantageous state and an advantageous state for the player, and it is possible to enhance the interest of the game.

  Means 10. A game machine characterized in that in any one of means 7 to means 9, the delay mode of the next internal hit is assigned according to which delay mode was entered at the previous internal hit.

  According to the means 10, since the delay mode allocation of the next internal hit is performed according to which delay mode was entered at the time of the previous internal hit, the delay of the past game flow is reduced. It is possible to predetermine the degree (so-called degree of humiliation) and the like. For example, if a delay mode with a large (or small) delay is entered at the previous internal hit, it is possible to increase the possibility of entering the same delay mode this time.

  Means 11. In any one of the means 1 to 10, the opportunity picture display control means controls the variable display means so as to display the opportunity picture immediately after the internal hit state is reached. .

  According to the means 11, since the trigger pattern is displayed immediately after the internal hit state is reached, the state shifts to the delay state without a time difference after the internal hit. Therefore, the gaming state can be managed appropriately.

  Means 12. In any one of means 1 to means 11, the opportunity picture display control means stops and displays the opportunity picture by pull-in control to the variable display means.

  According to the means 12, since the trigger picture is stopped and displayed by the pull-in control with respect to the variable display means, the trigger picture can be surely displayed.

  The basic configuration of various gaming machines to which the above means can be applied is shown below.

  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, there are “watermelon” symbols (for example, the 9th left belt) and “bell” symbols (for example, the 8th left belt) as the small role symbols from which the small roles are paid out. In addition, the middle belt and the right belt have a “cherry” symbol (for example, the middle belt No. 15) as a blank symbol which has nothing to do with the medal payout. 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 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. 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 (a right-down line and a right-up line) among the combination lines is enabled. 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 Will receive 5 medals.

  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 addition, when the “replay” symbol, which is a combination of the third special symbols, is aligned with the left, middle, and right on the active line, no medal is paid out. In other cases, that is, when the same symbols as the left, middle and right are not aligned on the active line, no medal is paid out.

  In the present embodiment, the “bell” symbol, “replay” symbol, “replay” symbol combination (hereinafter referred to as symbol combination A) or “bell” symbol, “bell” symbol, “replay” symbol. When the combination (hereinafter referred to as symbol combination B) is aligned with the left, middle, and right on the active line, a transition process to a specific game may be executed.

  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 the reels 42L, 42M, 42R are rotated at a constant speed, and a stop operation is performed by lighting a lamp (not shown) in 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.

  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.

  A hopper device 91 as a payout means for giving a medal to a player is composed of a storage tank 92 for storing the medal and a payout device 93 for paying out the medal to the player. 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 portion 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 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, there is provided a button-like credit insertion switch 77 for inserting three credited virtual medals as investment values at a time. The credit insertion switch 77 constitutes an input means for inputting the investment value together with the medal insertion slot 75. Further, if the medal insertion slot 75 is accompanied by an operation of directly inserting a medal by the player, the credit insertion switch 77 is only accompanied by an operation of inserting a virtual medal based on the storage memory. It can be said that it constitutes an indirect input means for indirectly inputting.

  The 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) is not reached. The lamp is turned on in a situation where the switch operation of the 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. Turns off under 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 an upper line and a 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 remaining number display unit 35 displays the number of stored coins, a virtual medal is inserted even when the credit insertion switch 77 is pressed, and a bet is made. .

  When the credit insertion switch 77 is pressed, three numerical values displayed on the remaining number display section 35 are decremented as three virtual medals are inserted, and all the effective line display sections 32 to 34 are displayed. Lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when the credit insertion switch 77 is pressed is not stored, for example, when the credit insertion switch 77 is pressed when the display of the remaining number display unit 35 is 2, etc. All of the numerical values in the remaining number display section 35 are decremented to 0, and a bet is placed for the number 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.

  A main controller 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. The substrate box includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other so as not to be opened by a sealing unit as a sealing means, whereby the substrate box is sealed.

  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. An inserted medal detection sensor 75a for detecting a medal inserted from 75, a credit insertion detection sensor 77a for individually detecting an operation of the credit insertion switch 77, a switching detection sensor 80a for detecting an operation of the changeover switch 80, and rotation of each reel 42 Set to reel index sensor 55 that individually detects the position (origin position), payout detection sensor 91a that detects medals paid out from hopper device 91, reset detection sensor 123a that detects the operation of reset switch 123, and setting key insertion hole 124 Detect that a key has been inserted Is connected to various sensors such as the constant key detection sensor 124a, 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. Therefore, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 24 VDC in this example output from the power supply unit 161a, and determines that the power is shut off when the drive voltage drops to, for example, less than 22 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. 10 and subsequent figures is stored in the ROM 152 described above as a part of the control program.

  The RAM 153 is configured so that a backup voltage is supplied from the power supply device 161 provided in the power supply box 85 even after the power of the slot machine 10 is cut off, and data can be held (backed up). 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. 12), and the restoration of each value written in the backup area is executed in the main process (see FIG. 13) when the power is turned on. The NMI terminal (non-maskable interrupt terminal) of the CPU 151 is configured to receive a power failure signal from the power failure monitoring circuit 161b when the power is interrupted due to the occurrence of a power failure or the like. The NMI interrupt process as a process is immediately executed.

  Next, an outline of the game of the slot machine 10 in the present embodiment will be described based on the schematic explanatory diagram of FIG. Here, for the sake of convenience, description will be made assuming that a big bonus game is used as a bonus game, and when the bonus game is simply described, the big bonus game is indicated.

  Internal game modes include a normal state mode, an RT mode 1 and an RT mode 2. Among these, in the normal state mode, a lottery process is performed with a predetermined probability, and for example, a big bonus game is won with a winning probability of 1/120. In addition, a replay game (replay) is won with a probability of 1 / 7.3. Furthermore, the 0 combination corresponding to the symbol combination A, B is drawn with a probability of 1/3. The symbol combinations A and B will be described in detail later. In addition, the small role is appropriately selected with a predetermined winning probability. In this mode, when the 0 winning combination is selected, there is no internal mode change and naturally no medal is paid out.

  On the other hand, RT modes 1 and 2 are game modes in a so-called replay time (RT) in which a replay game is won internally with a relatively high probability. The winning probability is about 1 / 1.8. That is, a replay game is internally established with a probability of more than half in each game. However, in the present embodiment, there is a so-called internal RT game in which display control is performed such that even if a replay game is established internally, the reel control or the like does not forcibly stop and display the combination of replay symbols. As a result, the probability that the stop symbol becomes a replay symbol (replay probability) is about 1 / 7.3, which is the same as the normal time. Further, when a 0-piece combination is selected with a probability of 1/3, a sorting process is performed at a predetermined ratio, and sorting to RT mode 1 or RT mode 2 is performed. In this mode, the lottery of the big bonus game is not performed.

  A flow of a game having the above-described three types of game modes is shown below.

  When the bonus game is won internally in the normal state mode, the RT modes 1 and 2 are distributed at a predetermined ratio. The ratio in this distribution varies depending on the internal state. Specifically, when the slot machine 10 is shipped or after the setting is changed, the probability of shifting to the RT mode 1 is 60%, whereas the probability of shifting to the RT mode 2 is 40%.

  Further, when the slot machine is not shipped or after the setting is changed, a different lottery is performed depending on whether the game was assigned to the RT game 1 or 2 at the time of the previous bonus game win. Specifically, when the game is distributed to the RT game 1 at the time of winning the bonus game, the RT mode distribution flag is set to 1, and it is confirmed that the RT mode distribution flag is 1 at the next bonus game winning. In such a case, the lottery is performed with the probability of shifting to RT mode 1 being 80% and the probability of shifting to RT mode 2 being 20%.

  Furthermore, when the bonus game is won and the RT game is assigned to the RT game 2, the RT mode assignment flag is set to 0, and it is confirmed that the RT mode assignment flag is 0 when the next bonus game is won. In such a case, the lottery is performed with the probability of shifting to RT mode 1 being 30% and the probability of shifting to RT mode 2 being 70%.

  When the RT mode 1 is determined internally, the symbol combinations that are stopped and displayed through the display windows 31L, 31M, and 31R are symbol combinations A (from left, “bell” symbol, “replay” symbol, “replay” “In combination with symbols”, an internal RT game with 20 games fixed is executed. In this mode, as described above, the winning probability of the internal replay game is higher than the normal state and is about 1 / 1.8. In addition, the 0 combination corresponding to the symbol combinations A and B is drawn with a probability of 1/3. In addition, the “Bell” symbol or the “Watermelon” symbol is drawn, but the winning probability of the “Bell” symbol is set to be overwhelmingly higher than the winning probability of the “Watermelon” symbol. Internally, since the bonus game is already won, the bonus game lottery is not performed. Further, when the “replay” symbol and the “bell” symbol are internally won, the reel control associated with the symbol becomes dominant, and the reel control associated with the bonus game is not performed.

  When the winning combination is won internally, the RT modes 1 and 2 are sorted again as described above. Specifically, the probability of becoming RT mode 1 is 49/50, and the probability of becoming RT mode 2 is 1/50. When the RT mode 1 is selected, the number of internal RT games is reset to 20 games when the combination of symbols stopped and displayed through the display windows 31L, 31M, 31R is the symbol combination A. When RT mode 2 is selected, the combination of symbols that are stopped and displayed through the display windows 31L, 31M, and 31R is symbol combination B (from the left, “bell” symbol, “bell” symbol, “replay” symbol). The transition to RT mode 2 takes place as a trigger.

  Next, when the RT mode 2 is determined internally, the combination of symbols stopped and displayed through the display windows 31L, 31M, and 31R is the symbol combination B. A game is carried out. In this mode, as in RT mode 1, the winning probability of the replay game is about 1 / 1.8, and the 0-piece combination corresponding to the symbol combination A, B is drawn at a probability of 1/3. , “Bell” symbol or “Watermelon” symbol is drawn. The winning probabilities of the “bell” symbol and the “watermelon” symbol are set in the same manner as in the RT mode 1. Further, the lottery of the bonus game is not performed as in the RT mode 1. Further, in this mode, when the “replay” symbol and the “bell” symbol are internally won, the reel control associated with the symbol becomes dominant, and the reel control associated with the bonus game is not performed.

  When the winning combination is won internally, RT modes 1 and 2 are sorted again in the same manner as RT mode 1. Specifically, the probability of becoming RT mode 1 is 1/50, and the probability of becoming RT mode 2 is 49/50. When the RT mode 1 is selected, the display mode is shifted to the RT mode 1 when the combination of symbols stopped and displayed through the display windows 31L, 31M, and 31R is the symbol combination A. When RT mode 2 is selected, the number of internal RT games is reset to one game when the combination of symbols that are stopped and displayed through the display windows 31L, 31M, and 31R is symbol combination B. It is.

  In RT modes 1 and 2, when all the internal RT game numbers are consumed (the remaining number of internal RT games is 0), the RT mode ends. As a result, the probability that the replay game is internally selected becomes 1 / 7.3, and the transition to the RT modes 1 and 2 when the winning combination is 0 is not performed. It is possible to stop the symbol to be on the active line (bonus release). In the game at the end of the RT mode, if the symbol attached to the selected bonus game does not stop on the active line, the game proceeds to the normal mode while the bonus game can be established. In addition, after the bonus game ends, the normal state mode is set.

  Subsequently, each control process executed by the CPU 151 in the main control device 131 will be described with reference to the flowcharts of FIGS. The processing of the CPU 151 is 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. 10 is a flowchart showing an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 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. 11 is a flowchart of timer interrupt processing periodically executed by the main control device 131, and a timer interrupt is generated by the CPU 151 of the main control device 131 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. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  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. 8) 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. 13 is a flowchart showing a main process in the main controller 131 that is executed after the power is turned 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 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. Specifically, the value of the checksum in the RAM 153 is checked to check whether the value is normal, that is, whether the value of the checksum including 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 zero, 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 used during 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 related 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 in step S503 will be described based on the flowchart of FIG.

  In step S601, a random number table for determining success / failure is selected based on the current setting state of the slot machine 10, the level of the small role probability, the internal game mode, and the like. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6” set by using a setting key (not shown). The random number table with the lowest transition probability is selected. When “setting 6” is selected, the random number table with the highest winning probability of winning combination and the highest transition probability to RT mode 2 is selected. 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 below a predetermined expected value, and small when it exceeds a predetermined expected value. A random number table with a low winning probability is selected. Furthermore, as described above, there are three types of internal game modes: normal mode, RT mode 1 and RT mode 2, and RT modes 1 and 2 are more internally replayed than normal mode. It is a random number table with a high probability of winning the game. In addition, as described above, there are also three types of random number tables of distribution probabilities to RT modes 1 and 2 when a big bonus game is won in the normal state mode.

  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. At this time, if the big bonus game is won, a lottery for RT modes 1 and 2 is also performed. In addition, even when a winning combination of 0 sheets is won in the state of RT modes 1 and 2, a sorting lottery of RT modes 1 and 2 is performed at the same time. 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.

  In the lottery process described above, the number of internal RT games when the RT modes 1 and 2 are won, the number of internal RT games in the RT modes 1 and 2 are subtracted, and the number of internal RT games is 0. In such a case, the random number table in the normal mode is selected.

  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 combinations” means that, for example, when a “watermelon” symbol is arranged on the upper line, a symbol combination B, which is a combination of zero, appears on the lower line, and multiple symbols are generated simultaneously. If you do. In addition, when the game mode is RT mode 1 or 2, the internal replay game winning probability is about 1 / 1.8, but the probability that the stop symbol becomes a replay symbol is about 1 / 7.3. The control is performed so that the slip table is forcibly stopped and displayed by the combination of replay symbols. It may also be performed at other times.

  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, 15 is stored as the upper limit in the payout amount storage area. In the case of a 0 combination corresponding to the symbol combinations A and B, no medal is paid out, so 0 is set in the planned payout number storage area.

  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. 19, 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 is placed on the current effective line. 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.

  20 and 21, 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 is 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, referring back to FIG. 18, when 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. 21B is performed, and this process ends. 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. 20), so it becomes 0 in step S913, and a positive 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.

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

  At the time of internal winning lottery (at the time of winning the bonus game), since the symbol combinations A and B are displayed as a combination of opportunity symbols, the player enters the RT mode 1 or 2 so that the player can By confirming the display of the combinations A and B, it is difficult or impossible to obtain a bonus game or the like until the RT modes 1 and 2 (delay by the delay means) are activated, that is, until the delay process is completed. I can understand. Therefore, the inconvenience caused by continuing the game unnecessarily without obtaining the privilege can be avoided.

  Since the RT modes 1 and 2 are sorted according to the state after the previous mode, the mode state each time, etc., it is possible to have a hit wave (change) in the game flow. It is possible to increase the interest of the game.

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

  (A) The various probabilities and roles described in the above embodiment are merely examples, and can be arbitrarily changed and embodied.

  (B) In the above embodiment, the symbol combination A (trigger symbol combination) displayed at the time of transition to the RT mode 1 is a combination of the “bell” symbol, the “replay” symbol, and the “replay” symbol. The symbol combination B (trigger symbol combination) displayed at the time of transition is a combination of “bell” symbol, “bell” symbol, and “replay” symbol, but this may be changed. Any configuration may be used as long as the reel unit 41 is controlled so that a predetermined symbol combination is displayed as a combination of the trigger symbols.

  (C) In the above embodiment, in RT modes 1 and 2, an internal RT game in which a replay symbol is not actually displayed even if an internal replay is won with high probability is implemented. Instead of this, when a replay is won internally, a replay symbol may be displayed each time. In this case, replay games (replays) occur frequently, and each game is continued while the decrease in handheld medals is suppressed.

  (D) In the above embodiment, in the RT modes 1 and 2, the lottery means such as the internal big bonus by the lottery means is not implemented, but this may be changed. For example, even if the winning lottery is performed by the lottery means, the lottery result may be invalidated. In this case, the configuration may be such that the sorting lottery in RT modes 1 and 2 is performed again, or the configuration in which the sorting lottery is not performed.

  (E) In the above embodiment, the RT mode sorting lottery is performed only when the big bonus game is won, but this may be changed. For example, in addition to the big bonus game winning, the RT mode sorting lottery may be performed even when the regular bonus game is won. In this case, the configuration may be such that the RT mode sorting lottery probability is changed between the big bonus and the regular bonus, or a configuration in which it is not changed.

  (F) In the above embodiment, the symbol combinations A and B are selected as a combination of 0 symbols as means for displaying the lottery results of the RT modes 1 and 2, but this may be changed. For example, as a means for displaying the lottery results in the RT modes 1 and 2, the symbol combinations A and B may be stopped and displayed on the effective line by reel control. In this case, in the internal lottery, the symbol combinations A and B may be drawn with a predetermined probability when no symbols are selected (the lottery result is lost). In the RT mode, the symbol combinations A and B may be selected at a predetermined ratio in the internal RT. Further, the symbol combinations A and B may be drawn independently. In other words, when the RT modes 1 and 2 are randomly drawn, the player can recognize the symbols associated with the RT modes 1 and 2 by stopping the predetermined symbols on the active line. .

  (G) In the above-described embodiment, the release factor of the big bonus is that the number of internal RT games is consumed, but other release factors may be used.

  (H) In the above embodiment, as described with reference to FIG. 9, after the internal bonus game is won, it is divided into one of the two RT modes by lottery. However, this may be changed. . For example, as the RT mode, three or more RT modes having different degrees of delay (so-called humiliation levels) are provided, and the three or more RT modes are distributed by lottery.

  Also, as shown in FIG. 22, it is possible to set only one RT mode. In the configuration of FIG. 22, when a bonus game is won internally in the normal state mode, whether to immediately establish a bonus game (bonus release) or shift to the RT mode is assigned by lottery. In this case, when transitioning to the RT mode after the internal bonus game is won, the symbol combination B as a combination of opportunity symbols is displayed. After that, a lottery for making the RT mode again (a lottery for staying in the RT mode) is performed with a predetermined probability. The other configuration basically conforms to FIG.

  (I) In the above embodiment, the slot machine 10 is a Max bet dedicated machine (three betting exclusive machine), but this may be changed to a slot machine capable of 1 bet and 2 bets.

  (J) In the above embodiment, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to such a configuration. For example, four or five reels are provided. It may be a slot machine provided in parallel or a slot machine having seven effective lines. Further, the present invention is not limited to the so-called A type slot machine, but can be applied to any slot machine such as B type, C type, A type and C type composite type, and B type and C type composite type. In any case, it is obvious that the same effects as the above-described embodiment can be obtained.

  (K) The symbols of the reels 42L, 42M, and 42R are not limited to pictures, numbers, characters, and the like, but may be geometric lines or figures. In addition, the design can be configured by light, color, or the like, the design can be configured by a three-dimensional shape or the like, and the design can be configured by combining these. That is, it is sufficient that the symbol has a function as identification information (identification information).

  (L) In the above-described embodiment, an example in which the slot machine 10 is embodied has been described. However, the present invention may be applied to a ball-use belt type game machine in which a slot machine and a pachinko machine are combined. That is, in the slot machine, instead of the medal insertion and medal payout functions, a gaming machine having a ball insertion and ball payout function such as a pachinko machine may be used. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming value in the gaming hall. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the location of the gaming machine can be solved.
