Description

  The present invention relates to a slot machine.

  A slot machine generally includes three reels, three reel stop buttons corresponding to each reel, and a start lever for starting a game. When the player depresses the start lever, all reels rotate at the same time, and each reel stops at the timing when the player depresses each reel stop button. Of the combinations of symbols arranged on the winning line in a state where the reels are stopped, a combination of symbols that gives a game value is called a role. When a combination of symbols composing a combination on the effective winning line is completed, a winning is made, and the player can obtain the number of medals corresponding to the winning combination. That is, when the state where the reels are stopped is a state (predetermined state) that is a combination of symbols constituting the winning combination, the winning combination is awarded and a game value corresponding to the winning winning combination is given.

  Here, winning is determined by two steps. The first step is called internal lottery. In the internal lottery, the lottery is executed at the operation timing of the start lever to determine which prize group will be won or lost, and internal lottery information indicating the lottery result is generated. Here, the prize group refers to a group of one or a plurality of roles and corresponds to a lottery category. That is, a prize group and a combination may correspond one-to-one, or a plurality of combinations may correspond to one prize group.

  In the second step, the reel stop position is controlled in accordance with the operation of the reel stop button. If the internal lottery information indicates a loss, even if the player operates the reel stop button at the timing when the symbol that constitutes a certain role reaches the valid winning line, the reel stop timing is delayed, Control is performed so that symbols constituting the winning combination do not stop on a valid winning line. On the other hand, if a prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly early, the pull-in control is performed so that the symbols constituting the role corresponding to the prize group stop on the winning line. The However, if the operation timing of the reel stop button is significantly deviated, no prize will be awarded. In other words, in order for a player to win a prize, it is necessary to win a prize group by internal lottery and align the winning prize group on an effective prize line.

  By the way, a certain type of slot machine includes a sub effect device in addition to the main reel. This effect device is composed of three reels or a liquid crystal display device. For example, Patent Document 1 discloses a slot machine that includes a variable display unit constituted by a reel and an image display unit as a rendering device, and interlocks changes in both symbols. In addition, this slot machine has a large image display unit arranged at the center of the housing and a small variable display unit arranged at the periphery, so that the player can easily see the effects displayed on the image display unit. is doing.

JP-A-2002-793 (Claim 1, Summary)

  However, in the conventional slot machine, the display of the main variable display unit and the sub image display unit are variably displayed, and when the player operates the reel stop button, both stop in conjunction with each other. Therefore, the display of the image display unit cannot be continued after the variable display of the main variable display unit is stopped. For this reason, there was a limit to the production of elaborate taste. Further, when the sub display is controlled independently of the main, there is a problem in that there is a contradiction in the display of both, for example, when the main indicates winning, the sub is not winning.

  The present invention has been made in view of the problems described above, and it is an object of the present invention to provide a slot machine that improves the taste of the production.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

  The slot machine according to the present invention includes a main reel (Ra1, Ra2, Ra3) on which a plurality of types of symbols are displayed as reel symbols, and an image display means (91) on which a plurality of types of symbols are displayed as display symbols. Start operation means (6), and when the player operates the start operation means (6), the main reels (Ra1, Ra2, Ra3) rotate and the display displayed on the image display means (91) When the symbols are variably displayed and the reel display mode, which is the display mode of the reel symbols in the stopped state of the main reels (Ra1, Ra2, Ra3), is a predetermined reel winning mode, a prize is awarded. The display state of the display symbols at the time when the variable display of the image display means (91) is finally stopped at the time of winning a prize by paying out a predetermined amount of game media The slot machine (1) whose image display mode is a predetermined image winning mode at the time of winning, the first control unit (31) for controlling the main reels (Ra1, Ra2, Ra3), and the image display unit Second control means (55) for controlling the image display of (91), and one of the first control means (31) or the second control means (55) is awarded or not A pre-determining unit that determines pre-winning information indicating whether or not to win; one control unit including the pre-determining unit controls the reel display mode or the image display mode according to the pre-winning information; The pre-winning information is supplied to the other control means, and the other control means refers to the pre-winning information, and when the pre-winning information indicates winning, the image display mode or the reel Display mode When the image display means (91) or the main reels (Ra1, Ra2, Ra3) are controlled so as to be in the reel winning mode or the image winning mode, and the pre-winning information indicates non-winning, the image It is preferable to control the image display means (91) or the main reels (Ra1, Ra2, Ra3) so that the display mode or the reel display mode does not become the reel winning mode or the image winning mode.

  According to the present invention, the pre-winning information is generated by one control means and is supplied to the other control means, so that the main reel and the image display means can match the winning / non-winning. Become. As a result, the first and second control means can acquire the information on winning / non-winning before starting the stop control. Therefore, even if the main reel and the image display of the image display means are controlled independently,・ You can match non-wins. Thereby, the image display means can execute various effects regardless of the operation of the main reel.

  For example, when the first control means (31) includes a pre-winning determination means, the result is as shown in FIG. 33A, and the first control means (31) controls the reel display mode according to the pre-winning information. In addition, the pre-winning information is supplied to the second control means (55), and the second control means (55) displays the image display mode and the reel display mode indicated by the pre-winning information according to the predetermined rule. The image display means (91) is controlled so as to correspond. On the other hand, when the second control means (55) includes a pre-winning determination means, the result is as shown in FIG. 33B, and the second control means (55) controls the image display mode according to the pre-winning information. In addition, the pre-winning information is supplied to the first control means (31), and the first control means (31) displays the reel display mode and the image display mode indicated by the pre-winning information according to the predetermined rule. The main reels (Ra1, Ra2, Ra3) are controlled so as to correspond to each other. Here, the pre-winning information is generated, for example, before the player operates the stop operation means for inputting the rotation stop of the main reel. A slot machine wins when it is won by internal lottery and the player's reel stop button is operated at a predetermined timing, but when the symbols constituting the role are in the reel symbol drawing range If you win the internal lottery, you will always win. In such a case, the internal lottery information indicating the result of the internal lottery corresponds to the pre-winning information. Further, in the slot machine described above, the predetermined reel winning mode includes a plurality of modes, the predetermined image winning mode includes a plurality of modes, and a predetermined rule that associates the reel winning mode with the image winning mode. Storage means for storing, wherein the pre-winning information designates the reel winning mode or the image winning mode at the time of winning, and the other control unit is configured to specify the pre-winning according to the predetermined rule. When the information indicates winning, the image display means or the main reel is controlled so that the image display mode or the reel display mode indicated by the pre-winning information becomes the reel winning mode or the image winning mode. The image display mode or the reel display mode does not become the reel winning mode or the image winning mode when the pre-winning information indicates non-winning. Serial image display means (91) or said main reel is preferably controlled (Ra1, Ra2, Ra3).

  Another slot machine according to the present invention includes a main reel (Ra1, Ra2, Ra3) on which a plurality of types of symbols are displayed as reel symbols, and an image display means for displaying a plurality of types of symbols as display symbols ( 91) and start operation means (6). When the player operates the start operation means (6), the main reels (Ra1, Ra2, Ra3) are rotated and displayed on the image display means (91). The display symbol to be displayed is variably displayed, and the reel display mode, which is the display mode of the reel symbol when the main reels (Ra1, Ra2, Ra3) are stopped, corresponds to any of a plurality of predetermined reel winning modes. When winning, the game medium of the quantity corresponding to the reel winning mode at the time of winning is paid out, and the variable display of the image display means (91) is finally stopped.

A first display portion 10 </ b> A is provided on the upper right side of the front door 3. On the other hand, a second display portion 10 </ b> B is provided in the middle center of the front door 3. Since the second display unit 10B is larger in size than the first display unit 10A and is arranged at the center of the slot machine 1 rather than the first display unit 10A, the second display unit 10B is more sensitive to players than the first display unit 10A. Easy to see. The first display unit 10A includes main reels Ra1, Ra2, and Ra3, which will be described later, and a first display window 4A provided on the front surface thereof. The second display unit 10B includes an image display device 91 and a second display window 4B provided on the front surface thereof. The first display window 4A and the second display window 4B are formed of a transparent material such as acrylic resin, for example.

  The image display device 91 may be any device as long as it can electrically display an image. For example, the image display device 91 can be configured by a liquid crystal panel, an organic EL panel, a plasma display, a CRT, or the like. The first display window 4A is provided with three pay lines L1 to L5 horizontally and two obliquely. Further, the image display device 91 displays the winning lines L1 to L5 as images. An auxiliary display unit 11 is provided on the left side of the first display window 4A. The auxiliary display unit 11 is composed of five LEDs respectively corresponding to the pay lines L1 to L5. When the player inserts medals or performs a bet operation to be described later, the number of pay lines L1 to L5 corresponding to the number of bets becomes valid. In this slot machine 1, the winning line L1 is valid when the number of bets is one, the winning lines L1 to L3 are valid when the number of bets is two, and the winning lines L1 to L1 when the number of bets is three. L5 becomes effective. Each LED constituting the auxiliary display unit 11 is turned on when the corresponding winning line L1 to L5 is valid, and is turned off when the corresponding winning line L1 to L5 is invalid. Thus, the player can know which winning lines L1 to L5 are valid. The pay lines L1 to L5 displayed on the image display device 91 can be identified when activated. For example, the activated winning line and the invalid winning line may be displayed with different colors, or may be displayed with different line thicknesses.

  Inside the first display window 4A, three rows of left, middle, and right reels Ra1, Ra2, and Ra3 (main reels) each having a plurality of types of symbols drawn as reel symbols on each outer peripheral surface are rotatably provided. ing. The rotation (variable display) and stop of the left, middle, and right reels Ra1, Ra2, and Ra3 as display columns are controlled by signals from a main board described later. Further, the above-described image display device 91 is provided inside the second display window 4B. The image display device 91 displays left, middle and right reels Rb1, Rb2, and Rb3 as display columns. On the left / middle / right reels Rb1, Rb2, and Rb3, 21 symbols and seven types of symbols are displayed as display symbols. The rotation (variable display) and stop of the left, middle, and right reels Rb1, Rb2, and Rb3 are controlled by signals from a sub-board described later.

  FIG. 2 shows the structure of the left / middle / right reels Ra1, Ra2, and Ra3, and FIG. 3 shows the detailed structure of the right reel Ra3. Each of the reels Ra1 to Ra3 has an annular shape, and various designs are printed on the surface thereof. Further, a light shielding film S that shields light is formed on the back surface of the right reel Ra3 except for a part thereof. In the portion where the light shielding film S is formed, light is not transmitted even if light is irradiated from the back side. On the other hand, the light shielding film S is not formed on each design portion, and the uneven member P for scattering light is formed on the back surface of the right reel Ra3. In addition, the reel of each design part is white and translucent. In the example shown in FIG. 3, the concavo-convex member P is formed inside the contour portion of the symbol “7”.

  A right reel illumination unit 670 is disposed on the inner peripheral surface side of the right reel Ra3. The right reel lighting unit 670 includes upper, middle and lower shades partitioned by a light shielding wall. A light source 67 is provided in each of the upper, middle, and lower shades. As the light source 67, a cold cathode tube, an LED, or a light bulb can be used.

  Further, a light shielding piece 491 is provided on a part of the right reel Ra3 so as to protrude from the reel body, and crosses the photo sensor 492 when the right reel Ra3 rotates. The photosensor 492 functions as a right reel position detection sensor 49A (see FIG. 7) that detects the rotational position of the right reel Ra3. The structure of the left reel Ra1 and the middle reel Ra2 and the peripheral configuration thereof are the same as the structure of the right reel Ra3 and the peripheral configuration thereof described with reference to FIG. 3, and the left reel Ra1 and the middle reel Ra2 are also rotated. Left / middle reel rotation position detection sensors 47A and 48A for detecting the above are provided. The output signals of these sensors are sent to the sub board.

  Returning to FIG. 1, the description will be continued. Below the second display window 4B, there is provided an operation unit OP on which various operation members for a player to execute a game are arranged. The operation unit OP includes a medal slot 5, a start lever 6, left / middle / right reel stop buttons 7a, 7b, 7c, a credit button 8, and a BET button 15.

  The medal slot 5 is provided on the lower right side of the second display window 4B so that a medal can be inserted. When one medal is inserted, the winning line L1 is activated, when two medals are inserted, the winning lines L1 to L3 are activated, and when three medals are inserted, the winning lines L1 to L5 are activated. Further, when the player inserts more than 3 medals, the slot machine 1 stores the number of medals of 4 or more as credits.

  The BET button 15 is provided on the lower left side of the second display window 4B. The BET button 15 is used for designating the number of medals bet by the player in one game. By operating the BET button 15 by the player, the stored medals can be bet without inserting medals from the medal insertion slot 5. Therefore, the winning lines L1 to L5 are appropriately enabled according to the number of medals designated by operating the BET button 15. The relationship between the number of medals designated by the operation of the BET button 15 and the valid pay lines L1 to L5 is the same as when medals are directly inserted.

  The start lever 6 is provided below the BET button 15. The start lever 6 is used by the player to instruct the start of the game. When the player depresses the start lever 6, the left / middle / right reels Ra1, Ra2, Ra3 and the left / middle / right reels Rb1, Rb2, Rb3 start to rotate at the same time, and the first display unit 10A and the second display unit The 10B symbol is variably displayed.

  Left, middle and right reel stop buttons 7 a, 7 b and 7 c are provided on the right side of the start lever 6. The left / middle / right reel stop buttons 7a, 7b, 7c are operated by the first display window 4A and the second display window 4B. The left / middle / right reels Ra1, Ra2, Ra3 and the left / middle / right reels Rb1, Rb2 , Rb3 are used to stop each.

  On the left side of the start lever 6, a credit button 8 for determining whether or not to store medals in the slot machine 1 is provided. The player can change whether the credit is valid or invalid by operating the credit button 8. In a predetermined case, medals are paid out to the player from the medal payout opening 10 a and stored in the medal tray 10.

<1-2: Relationship between roles and symbols>
FIG. 4 shows an example of symbols displayed on the left / middle / right reels Ra1, Ra2, Ra3 and the left / middle / right reels Rb1, Rb2, Rb3. As shown in this figure, 21 symbols and 6 types of symbols are displayed on each reel, and symbol numbers PN = 1 to 21 are assigned to each symbol. In the following description, when there is no need to distinguish between left, middle, and right, the left, middle, and right reels Ra1, Ra2, and Ra3 of the first display unit 10A are simply referred to as main reels, and the second display unit 10B The left / middle / right reels Rb1, Rb2, and Rb3 are simply referred to as sub-reels.

  FIG. 5 shows an example of the correspondence between the symbols on the sub reels and the symbols on the main reel. As shown in this figure, a symbol having a sub reel is associated with a symbol different for each of the left, middle, and right reels Ra1, Ra2, and Ra3. For example, the symbol “7” of the sub reel is associated with the symbol “1” of the left reel Ra1, the symbol “3” of the middle reel Ra2, and the symbol “4” of the right reel Ra3.

  The combination of symbols is broadly divided into a “role” that gives game value and a “losing” that has no value. The winning combination is a combination of symbols stopped on an effective pay line in a state where each main reel serving as a display row is stopped, in a predetermined manner. In this example, since the symbols of the main reel are associated with the symbols of the sub reels, a predetermined combination of symbols stopped on the effective winning line of the second display unit 10B in a state where each sub reel is stopped. The thing of an aspect corresponds to a role.

  FIG. 6 shows the relationship between the combination of symbols, sub reels and main reels. In the present embodiment, a BB role, an RB role, a plum role, a bell role, a cherry role, and a replay role are employed as the role. Arrangement of symbols constituting a combination on an effective winning line is called winning, and the number of medals corresponding to the winning combination is paid out. The medal is inserted into the slot machine 1 when starting the game, and is necessary for the player to continue the game. That is, the medal can be said to be a game medium having a game value such as continuation of the game.

  As shown in FIG. 6, the symbols constituting the role of the main reel are different in advance on the activated pay lines to be bet out of the plurality of pay lines L1 to L5 of the first display unit 10A. This is a mode in which the types of symbols are arranged, and the symbols constituting the role of the sub reel are modes in which the same type of symbols are arranged on the activated winning line among the plurality of winning lines L1 to L5 of the second display unit 10B. . The role of this embodiment includes the following.

  1) BB role This role is a combination of symbols of symbol number PN = 21 on the left reel Ra1, Rb1, middle reel Ra2, Rb2, right reel Ra3, Rb3, and the stop mode of the sub reel is "7-7-7" The stop mode of the main reel is “1-3-4”.

  2) RB role This role is a combination of symbols of symbol number PN = 5 in the left reel Ra1, Rb1, middle reel Ra2, Rb2, right reel Ra3, Rb3, and the stop mode of the sub reel is “BAR-BAR-BAR”. The stop mode of the main reel is “2-5-3”.

  3) Bell role This role consists of symbols with symbol numbers PN = 16, 12, 9 or 2 on the left reel Ra1, Rb1, symbols with symbol numbers PN = 20, 17, 13, 9 or 3 on the middle reels Ra2, Rb2. It is a combination of symbols of symbol numbers PN = 18, 13, 9, or 1 on the right reels Ra3 and Rb3, the stop mode of the sub reel is “bell-bell-bell”, and the stop mode of the main reel is “5-6-7”. It is.

  5) Plum role This role consists of symbols with symbol numbers PN = 18, 15, 9 or 2 on the left reels Ra1, Rb1, symbols with symbol numbers PN = 18, 14, 10, 6 or 1 on the middle reels Ra2, Rb2. It is a combination of symbols of symbol numbers PN = 19, 14, 10, 6 or 2 on the right reels Ra3 and Rb3, the stop mode of the sub reel is “Plum-Plum-Plum”, and the stop mode of the main reel is “4-1-1-”. 2 ”.

  6) Cherry role This role can be achieved by stopping the symbol number PN = 20, 13 or 6 on the left reels Ra1 and Rb1 on the activated one of the winning lines L1 to L5. It has nothing to do with it. That is, the stop mode of the sub reel is “Cherry-?-?”, And the stop mode of the main reel is “6-?-?”.

  7) Replay role This role consists of symbols with symbol numbers PN = 19, 17, 10 or 3 on the left reel Ra1, Rb1, symbols with symbol numbers PN = 19, 15, 11, 7 or 2 on the middle reels Ra2 and Rb2, It is a combination of symbols of symbol numbers PN = 20, 15, 11, 7 or 3 in the right reels Ra3 and Rb3, the stop mode of the sub reel is “Replay-Replay-Replay”, and the stop mode of the main reel is “7-4- 1 ”. Even if a replay role is established, no medals are paid out, but replay is possible. Re-playing means playing a game again without newly inserting medals.

  For these roles, game values to be given to the player for each role are determined in advance. For a combination, a combination with 1 to 15 payouts, a combination with an advantageous gaming state such as a big bonus or regular bonus, regardless of whether or not there is a payout due to winning, and a medal with no payout Without replaying the game, there is a role in which a re-game that can be played under the same number of medal insertion conditions is given again. Further, not all of these combinations are always determined as prizes in any gaming state. It is possible to have a combination that is established as a prize in one gaming state but not established as a prize in another gaming state. That is, the game value given to the player for each winning combination is determined in advance for each gaming state and is not always constant.

  In this embodiment, the game value given to the player in the normal gaming state is paid out by 15 pieces for the plum role, 10 pieces for the bell role, and 2 pieces for the cherry role, and the replay role can be replayed. It becomes a role to become.

  Among the various types of roles, the roles corresponding to relatively low game values such as a prize of 2 to 15 cards such as a bell role, a cherry role, and a plum role and a replay are collectively called a small role. . On the other hand, when the RB combination wins, 15 payouts are made and the gaming state shifts to a specific gaming state called a regular bonus (hereinafter abbreviated as “RB” where appropriate). With the regular bonus, the jack game can be played 12 times, and the RB period ends when the jack game is played 12 times or a maximum of 8 times is won. The jack game is played by betting one medal and enabling only the central pay line L1. A replay role is adopted as the role of the jack game. When the symbols constituting this combination are aligned with the winning line L1, the slot machine 1 pays out 15 medals. In other words, in the normal gaming state, even if the replay combination is complete, replay can only be performed, but in the jack game performed during the regular bonus period, 15 medals will be paid out when the symbols constituting the replay combination are complete. Can do. In addition, during the big bonus described later, a replay role is assigned to the regular bonus award. In addition, since a jack game that is not in the normal gaming state is played in the RB gaming state, it can be said that the RB gaming state is an advantageous gaming state for the player as compared to the normal gaming state.

  Further, when winning the BB combination, the gaming state shifts from a normal gaming state to a special gaming state called a big bonus (hereinafter, the big bonus is abbreviated as “BB” as necessary). During the big bonus period, it is possible to play a small role or RB role with a high winning probability state. This big bonus ends when the number of medals obtained exceeds a predetermined number (for example, 450). The big bonus is a more advantageous gaming state compared to the regular bonus. In the following description, the former is referred to as BB RB and the latter is referred to as a single RB in order to distinguish between the regular bonus in the big bonus and the regular bonus that has been won independently.

<1-3: Electrical configuration of slot machine>
FIG. 7 is a block diagram showing a control device that controls the game processing operation in the slot machine 1 and a circuit configuration including peripheral devices related to the present invention among those constituting the slot machine 1.

  The control device includes main board 30A and sub board 30B as main components. The main board 30A includes a main CPU 31, a clock generation circuit 32, a sequence generation circuit 33, a RAM 34, a ROM 35, a transmission timing control circuit 36, a data transmission circuit 37, an input port 38, and an output port 39.

  The main CPU 31 is connected to each component of the main board 30A excluding the transmission timing control circuit 36 via a bus (not shown). The main CPU 31 executes the first control program CP1 and controls each component. The first control program CP1 describes how to operate the entire slot machine 1. For this reason, the main CPU 31 functions as a control center of the slot machine 1. The clock generation circuit 32 includes an oscillation circuit including a crystal resonator, generates a reference clock signal CLK having a fixed period, and supplies the reference clock signal CLK to the main CPU 31 and the sequence generator 33.

  The sequence generator 33 is composed of a high-speed ring counter, and counts the reference clock signal CLK to generate count data CD. The numerical value range of the count data CD is, for example, 0 to 59999, depending on the contents stored in the prize group lottery table TBL1 described later. The count data CD is always supplied to the main CPU 31, and the main CPU 31 detects the timing when the player depresses the start lever 6, and samples the count data CD at the timing to generate the sampling data SD.

  Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pushed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value sampled from a random number. Since the sequence generator 33 operates in synchronization with the reference clock signal CLK, the cycle of the count data CD is extremely short. For example, if the frequency of the reference clock signal CLK is 30 MHz, the time required for the value of the count data CD to change from “0” to “59999” is 2 msec. Therefore, even if the player can know the value of the count data CD by unauthorized means, it is impossible to cause the main CPU 31 to generate the sampling data SD having a desired value by operating the start lever 6.

  Next, the RAM 34 functions as a work area of the main CPU 31 and stores intermediate results of arithmetic processing, data generated as necessary, flags used for various controls, and the like. For example, internal lottery data ISD indicating the result of the internal lottery is stored in the RAM 34.

  In addition to the first control program CP1, the ROM 35 stores a prize group lottery table group TBL1, a stop table group TBL2, a winning symbol combination table TBL3, and the like. In the winning symbol combination table TBL3, combinations of winning symbol combinations and medal payout numbers for winning combinations are stored in association with each other.

  As described above, the types of roles in the slot machine 1 of the present embodiment include the BB role, the RB role, the bell role, the cherry role, the plum role, and the replay role. The establishment of the BB combination is an opportunity to shift to the big bonus, while the establishment of the RB combination is an opportunity to shift to the regular bonus. In addition, the game value that a player can acquire varies depending on the type of the small role. Since the control of the slot machine 1 requires control according to the difference in game value, it is convenient to classify various roles by paying attention to the game value. Therefore, the slot machine 1 of this embodiment assigns each prize group corresponding to these roles. The prize group corresponding to the BB role is the BB prize, the prize group corresponding to the RB role is the RB prize, the prize group corresponding to the bell role is the Bell prize, the prize group corresponding to the plum role is the plum prize, and the award corresponding to the cherry role The group is called the Cherry Prize, and the prize group corresponding to the replay role is called the Replay Prize.

  The prize group lottery table group TBL1 includes a plurality of prize group lottery tables. The main CPU 31 performs an internal lottery using a prize group lottery table selected according to the gaming state. As a prize group lottery table, a table used for a normal game, a table used for a big bonus game, and a table used for a regular bonus game are prepared.

  FIG. 8 shows the stored contents of the prize group lottery table TBL11 for the base game. As shown in this figure, the prize group lottery table TBL11 stores lottery division data in the first to seventh storage areas ADR1 to ADR7, respectively. The value of the lottery category data indicates the width of the lottery category corresponding to each prize group. For example, the lottery classification data stored in the first storage area ADR1 corresponds to the loss, and the value is “54000”. The lottery classification data stored in the seventh storage area ADR7 corresponds to the BB prize, and its value is “300”. Therefore, the probability of winning the BB prize is 1/180 of the probability of winning the loss.

  FIG. 9 is a flowchart showing the operation of the main CPU 31 in the internal lottery process using the prize group lottery table TBL11. First, the main CPU 31 performs an initialization process (step S1). Specifically, the value of the variable N is cleared to “0” and the value stored in the internal register is cleared to “0”.

  Next, the main CPU 31 stores the sampling data SD in the internal register (step S2), and subsequently changes the value of the variable N to N + 1 (step S3). Thereafter, the main CPU 31 reads lottery classification data from the Nth storage area (step S4). In the process immediately after the initialization process, since the value of the variable N is “1”, the lottery classification data is read from the first storage area ADR1. The value in this case is “54000”.

  Next, the main CPU 31 reads the stored contents of the internal register, adds the read data value and the lottery classification data value, and stores the added value in the internal register (step S5). As a result, the content stored in the internal register is updated from the original data value to the added value.

  Next, the main CPU 31 determines whether or not the added value is greater than or equal to the reference value (step S6). The reference value is equal to the sum of the values of the lottery classification data stored in the first to seventh storage areas ADR1 to ADR7.

  If the added value is less than the reference value, the main CPU 31 returns the process to step S3, and repeats the processes from step S3 to step S6 until the added value becomes equal to or greater than the reference value. When the added value is equal to or greater than the reference value, the main CPU 31 advances the process to step S7, determines a prize group according to the value of the variable N, and generates internal lottery data ISD. Specifically, when N = 1, it is lost, when N = 2, a replay prize, when N = 3, a cherry prize, when N = 4, a bell prize, when N = 5, a plum prize, when N = 6, an RB prize When N = 7, it is determined that the BB prize is won. As a result, as shown in FIG. 8, the correspondence between the sampling data SD and the prize group is lost at SD = 59999-6000, replay prize at SD = 5999-4200, cherry prize at SD = 4199-3000, It corresponds to the Bell Award at SD = 2999-1740, the Plum Award at SD = 1799-900, the RB Award at SD = 899-300, and the BB Award at SD = 299-0.

  Then, the main CPU 31 generates internal lottery data ISD based on the determination result. The internal lottery data ISD is 8-bit data. The first bit is the BB prize, the second bit is the RB prize, the third bit is the Bell prize, the fourth bit is the plum prize, the fifth bit is the cherry prize, Each bit is assigned a replay award. If any prize is won by internal lottery, the main CPU 31 sets the value of the corresponding bit to “1”, and if not, sets the value of the bit to “0”. Therefore, by referring to the internal lottery data ISD, it is possible to know whether the player has won or lost, and the winning group that has won.

  In the following description, the first bit of the internal lottery data ISD is called a BB winning flag, and the second bit is called an RB winning flag. Then, setting the BB winning flag or the RB winning flag to “1” is called “set”, and setting “0” is called “clear”. The same applies to small roles. With regard to a small role, even if a game is won by an internal lottery, no medal will be paid out unless the game is won. However, if the RB prize and the BB prize are won in an internal lottery of a certain game, the BB prize flag or the BB prize flag is not cleared until the game is won in the subsequent game without clearing the BB prize flag or the RB prize flag. The RB winning flag is not deleted. This is called carrying over the winning flag.

  Next, the stop table group TBL2 is composed of a plurality of stop tables. In each stop table, a symbol number PN displayed on the center winning line L1 and shift frame number data indicating the shift frame number are stored in association with each other. Here, the number of misplaced frames is the number of symbols that advance from when the player depresses each of the left / middle / right reel stop buttons 7a, 7b, 7c until each left / middle / right reel Ra1, Ra2, Ra3 stops. I mean.

  Since each of the left, middle, and right reels Ra1, Ra2, and Ra3 rotates at high speed, even if the player operates the stop button aiming at a specific symbol, skill is required to stop the desired symbol. There are individual differences in the mastery of the stop button operation. In particular, it is difficult for a player with low moving eyesight to stop a desired symbol. On the other hand, a highly skilled player can operate the stop button when a desired symbol is displayed on the winning line.

  However, in order for a low-skilled player to enjoy the game, it is necessary to make it easy to align the symbols to some extent. On the other hand, when the result of the internal lottery is lost, it is necessary to control the rotation of the reel so that the combination is not established There is. The stop table is used to control such reel rotation. The stop positions of the left, middle and right reels Ra1, Ra2 and Ra3 are determined with reference to the stop table.

  Returning to FIG. 7, the description will be continued. The transmission timing control circuit 36 and the data transmission circuit 37 shown in the figure transmit various information generated by the main CPU 31 to the sub-board 30B. The information transmitted to the sub-board 30B includes internal lottery data ISD, effect adjustment time, start lever 6 operation timing, stop symbol number, stop button number for specifying the stopped reel stop button, and the like.

  Next, the input port 38 is an input interface for signals supplied from various sensors described later. On the other hand, the output port 39 is an output interface for supplying control signals to each motor and various devices.

  The main input signal generating means connected to the input port 38 and generating various input signals includes the following. The inserted medal detection sensor 41 detects a medal inserted through the medal slot 5 and generates one output pulse for one medal. Therefore, the main CPU 31 can detect the number of medals inserted by counting the output pulses.

  The BET button sensor 42 detects the operation of the BET button 15. The start lever sensor 43 detects the operation of the start lever 6. The left / middle / right reel stop button sensors 44, 45, 46 detect the operation of the left / middle / right reel stop buttons 7a, 7b, 7c, respectively, and output stop instruction signals 44a, 45a, 46a. The left / middle / right reel position detection sensors 47A, 48A, 49A detect the rotation positions of the left / middle / right reels Ra1, Ra2, Ra3, and generate reference point passing signals 47a, 48a, 49a (detection signals). .

  The right reel position detection sensor 49A includes a photosensor 492, an amplifier, and a comparator shown in FIGS. Photosensor 492 includes a light emitting portion and a light receiving portion. When the light receiving unit outputs a light reception signal at a level corresponding to the amount of light received, the amplifier amplifies the light reception signal. The comparator compares the output signal of the amplifier with a predetermined threshold value to generate a reference point passing signal 49a, and outputs this as an output signal of the right reel position detection sensor 49A. When the right reel Ra3 rotates, the light shielding piece 491 shown in FIG. 2 passes through the photosensor 492 once per rotation. Therefore, the rotation position of the right reel Ra3 can be detected by the reference point passage signal 49a. The left / middle position detection sensors 47A and 48A are configured in the same manner as the right reel position detection sensor 49A.

  Main means connected to the output port 39 and supplied with various output signals include a medal payout mechanism 70 and left / middle / right reel drive motors 51A, 52A, 53A. The medal payout mechanism 70 includes a hopper that stores medals in the slot machine 1, a disk mechanism that discharges medals from the hopper to the medal receiver 10, a counter that counts medals, and the like, based on a control signal from the main CPU 31. To eject the indicated number of medals.

  The left / middle / right reel drive motors 51A, 52A, and 53A are motors that respectively rotate the left / middle / right reels Ra1, Ra2, and Ra3, and in this example, are constituted by stepping motors. Therefore, the main CPU 31 adjusts the number of pulses of the drive signals 51a, 52a, 53a supplied to the left / middle / right reel drive motors 51A, 52A, 53A, thereby controlling the left / middle / right reels Ra1, Ra2, Ra3. It is possible to accurately determine the stop position.

  Each motor 51A, 52A, 53A is configured to rotate once by 420 pulses. As described above, since 21 symbols are formed on each of the reels Ra1, Ra2, and Ra3, one symbol can be advanced by supplying 20 pulses to the motor. Further, the main CPU 31 counts the number of pulses supplied to each of the motors 51A, 52A, 53A, and holds the count result as each position data MD1, MD2, MD3. The values of the position data MD1, MD2, and MD3 are cleared at the timing when the reference point passage signals 47a, 48a, and 49a become active.

  FIG. 10 is a timing chart showing the relationship among the reference point passage signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3. As shown in this figure, when the reference point passing signal 49a rises from the low level to the high level at time t1, the value of the position data MD3 is cleared. Time t1 is timing when the light shielding piece 491 shown in FIG. At this time, the symbol (7) of the symbol number PN = 1 shown in FIG. 4 is displayed in the middle of the display window 4A as the rotational position of the right reel Ra3. In other words, the attachment position of the light shielding piece 491 and the photosensor 492 is determined so that the symbol is displayed in the middle of the display window 4A.

  When 20 pulses are supplied as the drive signal 53a to the right reel drive motor 53 during the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel Ra3 by 1/21. As a result, the symbol (2) of symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4A. Thereafter, the symbols are sequentially displayed in the same manner, and when time t3 is reached, the right reel Ra3 makes one rotation and the symbol (7) with the symbol number PN = 1 is displayed again. Thus, since the reference point passing signal 49a, the symbol number PN, the drive signal 53a, and the position data MD3 are closely related, the main CPU 31 detects the symbol display state based on the position data MD3. Can do.

  As for the left reel Ra1 and the middle reel Ra2, as with the right reel Ra3 described above, the main CPU 31 can detect the display state of the symbols based on the position data MD1 and MD2.

  Next, FIG. 11 is a block diagram showing a detailed configuration of the sub-board 30B and its peripheral configuration. The sub board 30B includes a sub CPU 55, a data input circuit 56, a clock generation circuit 57, a ROM 58, a RAM 59, a VRAM 90, and an image display device 91.

  The sub CPU 55 functions as a control center for controlling the sub board 30B in accordance with the second control program CP2. The data input circuit 56 is an interface that receives various types of information transmitted from the data transmission circuit 37 described above and delivers them to the sub CPU 55. The clock generation circuit 57 generates a clock signal and supplies it to the sub CPU 55.

  In addition to the second control program CP2, the ROM 58 stores a stop data table group and a symbol arrangement table. The symbol arrangement table stores a symbol number and a symbol type in association with each sub reel. The RAM 59 functions as a work area for the sub CPU 55 and stores data, flags, and the like that are being processed according to the second control program CP2.

  In addition, the ROM 58 stores symbol data DG indicating an image of each symbol arranged on the sub reel. The symbol data DG is managed separately for each symbol type, and is read from the ROM 59 as necessary. In this example, seven symbol data DG1 to DG7 such as “7”, “plum”, “bell”, “cherry”, “replay”, and “BAR” are stored in the ROM 58. The ROM 58 stores address information indicating the storage areas of the symbol data DG1 to DG7 and symbol codes for identifying the symbol data in association with each other. The sub CPU 55 generates a sequence of symbol codes according to the control program CP2, controls the symbol display order, obtains address information corresponding to the symbol codes, reads the symbol data DG1 to DG7 from the ROM 58, and reads the VRAM 90. Forward to. The ROM 58 functions as an image storage unit that stores the symbol data DG.

  Further, data is sequentially read from the VRAM 90 and supplied to the image display device 91 as display image data. The sub CPU 55 writes the symbol data DG read from the ROM 58 in the vertical blanking period to the VRAM 90, and reads and supplies the display image data from the VRAM 90 in the display period. That is, the sub CPU 55 functions as a supply unit that supplies display image data to the image display device 91 and also functions as an update unit that updates the storage contents of the VRAM 90.

  The sub CPU 55 controls the display position of the symbol on the screen. In order to draw so that symbols flow from the top to the bottom of the screen, the Y-axis direction of the screen is incremented for each step. When changing the movement speed of the symbol, for example, control is performed so that the Y-axis address is moved by one step every 10 vertical blanking periods and is changed every 8 vertical blanking periods. Since the symbol movement speed is determined by the relationship between the display image data update cycle and the write address increment, the movement step may be changed with the update cycle constant. In addition, continuous values are used as addresses for designating storage areas of the VRAM 90, and there is no concept of X-axis and Y-axis. Therefore, the sub CPU 55 converts the X and Y addresses into real addresses and writes the symbol data DG into a predetermined storage area.

  Further, the sub board 30B includes a sound LSI 61, an audio ROM 62, and an audio processing circuit 63. The sound ROM 62 stores sound data for generating various sound effects. The sound LSI 61 reads out sound data from the sound ROM 62 at a predetermined timing based on a command from the sub CPU 55, performs a predetermined process, and outputs it to the sound processing circuit 63. The audio processing circuit 63 DA-converts the sound data to generate an audio signal, amplifies the audio signal to a predetermined level, and supplies it to the speaker 68. Thereby, a sound effect is emitted from the speaker 68.

  By the way, in order to prevent the storage device such as the ROM and the sub board 30B main body from being illegally replaced, a so-called “sealing” may be performed when fixing the case housing the sub board 30B to the main body 2. . For the sealing, a sealing member having identification information such as letters and numbers is used. When removing the sub board case from the gaming machine main body, the member having the identification information which is a seal must be destroyed, and the removal of the sub board case is monitored based on the destruction.

  FIG. 12 is a perspective view showing a sealing structure of the sub-board 30B. A sub-board case 300 is disposed on the side surface of the main body 2. The sub board case 300 accommodates the sub board 30B therein. The sub-board case 300 is fixed to the main body 2 using two screws 301 and 302 above the sub-board case 300. Through holes 303 and 304 are provided in the heads of the screws 301 and 302. The sealing member 305 provided with identification information is passed through the through holes 303 and 304.

  The sealing member 305 has an insertion part 30a and a band part 30b, and has a single band shape. One end thereof is inserted into the insertion portion 30a at the other end thereof to form a ring, and the inserted one end cannot be removed due to the geometrical characteristics of the insertion portion 30a and the band portion 30b. To release the ring, the band 30b is cut with a tool such as a nipper. In the embodiment, a member generally called “binding band” used for bundling a plurality of electric wirings is used. The sealing member 305 is a metal such as resin or wire having elasticity that can be easily bent by human power, and allows the heads of the two screws to communicate with each other even if the directions of the through holes 303 and 305 are not aligned. be able to. In the case of resin, a plate-like portion that gives identification information may be integrally formed at the end of a strip-like portion that passes through the through holes 303 and 304 as shown in the figure. In the case of a metal such as a wire, a plate-like member that provides identification information may be provided separately from the wire, or may be formed integrally by forging or welding.

  Although not shown in the drawing, a projection inserted into the main body 2 is provided below the sub-board case 300 and is fixed by screws 301 and 302 above the sub-board case 300, so that the lower side of the sub-board case 300 is separated from the main body 2. It will not come off. Therefore, it is not necessary to screw the lower side of the sub board case 300 with screws.

<1-4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. FIG. 13 is a flowchart showing an operation that the main CPU 31 controls from the start to the end of one game. The main CPU 31 determines whether or not the player has made a bet operation based on detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to step S12.

  In step S12, it is determined whether or not a game start operation has been performed. Specifically, the main CPU 31 determines whether or not the player has operated the start lever 6 based on the detection signal of the start lever sensor 43. When the player operates the start lever 6, the main CPU 31 executes a prize lottery according to the first control program CP1 (step S13). At this time, the main CPU 31 sets a prize group lottery table according to the game mode. Specifically, a table corresponding to a game mode such as a base game, an RB game, or a BB game is selected from the prize group lottery table group TBL1. In this case, the main CPU 31 refers to the RB flag, BB flag, etc. stored in the RAM 34 to specify the game mode of the game, and selects a table based on the result. For example, if the game is a normal game (including an AT game), it is detected that the RB flag and the BB flag are cleared, and the prize group lottery table TBL11 is selected from the prize group lottery table group TBL1. . Thereafter, the main CPU 31 executes an internal lottery process using the set prize group lottery table TBL1, and sets a winning flag indicating a winning group or a winning combination.

  The internal lottery process and the setting of the winning flag are performed according to the following procedure. First, the main CPU 31 samples the count data CD and obtains the sampling data SD at the timing when the detection signal of the start lever sensor 43 becomes active. Secondly, the main CPU 31 refers to the prize group lottery table and generates internal lottery data ISD. For example, if the prize group lottery table TBL11 shown in FIG. 8 is used and the value of the sampling data SD is “150”, the internal lottery data ISD indicates that the BB prize is won. In this case, the main CPU 31 sets a winning flag in the internal lottery data ISD in the first bit of the internal lottery data ISD.

  Next, the main CPU 31 selects a reel stop data group based on the internal lottery data ISD (step S14). For example, based on the BB flag indicating that the BB game is being performed, it is determined whether or not the BB game is being performed. While the normal stop table is selected, when the determination result is affirmative, the main CPU 31 selects the BB stop table from the stop table group TBL2.

  Thereafter, the main CPU 31 transmits internal lottery data ISD (internal lottery information) to the sub-board 30B, and subsequently transmits gaming state information to the sub-board 30B. The game state information indicates the game state being executed. The gaming state means a type of game such as a normal game, an RB game, a BB game, or an AT game.

  Next, the main CPU 31 determines whether or not there is a possibility of winning based on the internal lottery data ISD (step S17). If any winning flag is set in the internal lottery data ISD, it is determined that there is a possibility of winning, but if no winning flag is set, that is, if the internal lottery result is lost. It is determined that there is no possibility of winning. The possibility of winning may be determined in consideration of the selection result of the stop table. For example, even if the BB prize is won by an internal lottery, there is a slot machine that cannot immediately arrange the winning symbols and allows the winning symbols to be aligned only when a predetermined condition is satisfied. Such a slot machine is called a stock machine because it stores the BB prize winnings inside. In this type of slot machine, during the period from when the BB prize is won internally until a predetermined condition is satisfied, a stop table is selected in which the winning symbol cannot be aligned on an effective winning line. Therefore, the main CPU 31 may determine the possibility of winning based on the internal lottery data and the selection result of the stop table. Specifically, winning is possible when the internal lottery data ISD indicates that an award has been won for some award and the selected stop table allows the winning of an award that has been won internally. In other cases, it may be determined that there is no possibility of winning.

  Next, when it is determined that the condition of step S17 is affirmed, the main CPU 31 sets a payout delay time. In this example, the main CPU 31 determines the payout delay time by lottery. As the payout delay time, for example, a plurality of times such as t1 = 5 seconds and t2 = 10 seconds are determined in advance, and the main CPU 31 provides payout delay time information indicating the payout delay time selected as the lottery result. Generate. Here, the payout delay time information may directly indicate the payout delay time, or it may indicate which payout delay time is selected from a plurality of predetermined payout delay times. There may be. In the latter mode, the payout delay time is converted into a command. For example, 5 seconds may be associated with T1 and 10 seconds may be associated with T2, and T1 or T2 may be generated as payout delay time information. Good. In this case, it is preferable that the association between the command type (T1, T2) and the payout delay time (5 seconds, 10 seconds) is held in the memory on both the main board 30A and the sub board 30B. Note that when there is no medal payout as in the replay prize, the payout delay time need not be set. Furthermore, as t1 = 0 seconds, it may be included in the selection target that there is no payout delay. When the payout delay time is determined in this way, the main CPU 31 advances the process to step S19 and transmits payout delay time information for instructing the payout delay time to the sub-board 30B.

  Next, the main CPU 31 starts rotation of the main reel (step S20). Specifically, the drive signals 51a to 53a are activated. Then, the rotation shafts of the left / middle / right reel drive motors 51A to 53A start to rotate, and the main reels Ra1 to Ra3 rotate accordingly.

  Next, the main CPU 31 determines whether or not all main reels are stopped (step S21). If all the main reels are not stopped, the main CPU 31 advances the process to step S22, and determines whether or not the left reel Ra1 is stopped based on the stop instruction signal 44a. When the stop instruction signal 44a is active, it is determined that the stop operation of the left reel Ra1 has been performed, and the stop process of the left reel Ra1 is executed (step S23). At this time, the main CPU 31 generates left stop information indicating that the left reel Ra1 has been stopped, and transmits the left stop information to the sub CPU 55. In the stop process of the left reel Ra1, the number of misaligned frames is read with reference to the stop table, and the rotation of the left reel Ra1 is controlled so that the symbol advances by the number of misaligned frames read.

  If it is determined that the condition of step S22 is negative, the main CPU 31 advances the process to step S24, and determines whether or not the middle reel Ra2 is stopped based on the stop instruction signal 45a. If it is determined that there has been a stop operation for the middle reel Ra2, a stop process for the middle reel Ra2 is executed (step S25). At this time, the main CPU 31 generates middle stop information indicating that the middle reel Ra <b> 2 has been stopped, and transmits it to the sub CPU 55. When it is determined that there is no stop operation for the middle reel Ra2, the main CPU 31 determines whether or not the right reel Ra3 is stopped based on the stop instruction signal 46a (step S26). If it is determined that the right reel Ra3 has been stopped, the right reel Ra3 is stopped (step S27). At this time, the main CPU 31 generates right stop information indicating that the right reel Ra3 has stopped, and transmits the right stop information to the sub CPU 55. The stop process for the middle reel Ra2 and the right reel Ra3 is the same as the stop process for the left reel Ra1.

  On the other hand, when it is determined that the condition of step S26 is negative, the main CPU 31 returns the process to step S21 and repeats the process from step S21 to step S27 until all the reels stop. When all the reels stop, the main CPU 31 determines whether the reel display mode is a predetermined reel winning mode when the reel symbol display mode in the stopped state of the main reels Ra1 to Ra3 is the reel display mode. judge. Here, the reel winning mode means an arrangement of reel symbols to be awarded. For example, when the winning line L1 is activated, a mode in which 7-7-7 is aligned on the winning line L1 corresponds to a reel winning mode, while 7-7- on the not-valided winning line L2. A mode in which 7 is aligned does not correspond to a reel winning mode. When the reel display mode matches the predetermined reel winning mode, winning is made, and the main CPU 31 transmits winning information specifying the reel winning mode to the sub CPU 55 (step S28).

  Next, the main CPU 31 determines whether or not a prize has been won (step S29). If a prize has been won, the payout of medals is delayed by the payout delay time set in step S18 (step S30). After the lapse, the medal is paid out and one game is finished (step S31). Note that the process of one game is also ended when no winning is made.

  Next, processing of the sub CPU 55 will be described. FIG. 14 is a flowchart showing the processing contents of the sub timer interrupt processing executed by the sub CPU 55. The sub timer interrupt processing program is stored in the ROM 58 as a program module, and the sub CPU 55 executes the program module when detecting an interrupt signal generated at a predetermined time interval.

  The sub CPU 55 determines whether or not there is a command input from the main CPU 31 (step S41). If there is a command input, the process proceeds to step S42. And the next interrupt signal is monitored.

  In step S42, it is determined whether or not the command is game information. The game information includes internal lottery data ISD, game state information, and payout delay time information. When it is determined that the condition of step S42 is affirmed, the sub CPU 55 acquires internal lottery data ISD, gaming state information, gaming state information, and payout delay time information (steps S43 to S45), and gaming information. An acquisition flag is set (step S46).

  If the determination in step S42 is negative, the sub CPU 55 determines whether the command is left stop information (step S47). If the command is left stop information, the sub CPU 55 acquires left stop information. Then, the left stop information acquisition flag is set (step S49). If the determination in step S47 is negative, the sub CPU 55 determines whether or not the command is medium stop information (step S50). If the command is medium stop information, the sub CPU 55 acquires medium stop information. (Step S51), an intermediate stop information acquisition flag is set (Step S52). If the determination in step S50 is negative, the sub CPU 55 determines whether the command is right stop information (step S53). If the command is right stop information, the sub CPU 55 obtains right stop information. Then, a right stop information acquisition flag is set (step S55).

  Thereafter, the sub CPU 55 determines whether or not the command is winning information (step S56). If the command is winning information, the sub CPU 55 acquires the winning information and sets a winning information acquisition flag (steps S57 and S58).

  Next, the processing content of 1 sub game processing is demonstrated. 15 and 16 are flowcharts showing the processing contents of one sub game process executed by the sub CPU 55, and FIG. 17 is a flowchart showing the processing contents of the variable mode determination process. First, the sub CPU 55 determines whether or not game information has been acquired from the main CPU 55 based on the game information acquisition flag (step S60). Specifically, if the game information acquisition flag is “1”, the sub CPU 55 determines that the game information has been acquired, and executes variable mode determination processing. In the variable mode determination process, parameters indicating the variable display contents of the left, middle, and right reels Rb1, Rb2, and Rb3 displayed on the image display device 91 are determined. P1, P2, and P3 respectively indicate the types of the left, middle, and right reels Rb1, Rb2, and Rb3, and subscripts r, s, e, and t are added to the reels as parameters. “R” represents a rotation direction, “s” represents a start pattern, “e” represents a stop pattern, and “t” represents a constant speed time.

  As shown in FIG. 17, in the variable mode determination process, the sub CPU 55 determines the rotation direction, the start pattern, and the constant speed time for each reel based on at least one of the game state information and the internal lottery data (steps). S100 to S102). In this example, the rotation direction of the left reel Rb1 is represented by P1r, the rotation direction of the middle reel Rb2 is represented by P2r, and the rotation direction of the right reel Rb3 is represented by P3r. There are four types of rotation directions: vertical forward (from top to bottom), vertical reverse (from bottom to top), horizontal forward (from right to left), and horizontal reverse (from left to right). Indicates vertical rotation, “1” indicates vertical rotation, “2” indicates horizontal rotation, and “3” indicates horizontal rotation. FIG. 18A shows the direction of rotation. For example, if P1r = P2r = P3r = 0, the left / middle / right reels Rb1, Rb2, Rb3 rotate from top to bottom as shown in FIG. If P1r = P3r = 0 and P2r = 1, the left and right reels Rb1 and Rb3 rotate from top to bottom and the middle reel Rb2 rotates from bottom to top as shown in FIG. 18B. . Further, if P1r = P2r = 2 and P3r = 3, the left and middle reels Rb1 and Rb2 rotate from right to left as shown in FIG. 18D, and the right reel Rb3 rotates from left to right. .

  Next, the start pattern defines a speed change from a state where each reel is stopped to a constant rotational speed, and is normally (0), low speed 1 (1), low speed 2 (2). , There are four patterns of delay (3). In this example, the start patterns of the left / middle / right reels Rb1 to Rb3 are represented by P1s to P3s. FIG. 19 shows a start pattern.

  Next, the constant speed time means the time for which the predetermined speed is continued after reaching the predetermined speed, and is of four types: interlock (0), 3 seconds (3), 10 seconds (10), and 20 seconds (20). There is. Among these, interlocking means that it is rotated in the same time as the main reel. In this example, the constant speed times of the left, middle and right reels Rb1 to Rb3 are represented by P1t to P3t. FIG. 20 shows a starting pattern. In the interlocking operation, when the rotation of the main reel is stopped, the rotation of the sub reel is stopped.

  Returning to FIG. When the process of step S102 ends, the sub CPU 55 determines a stop pattern based on the payout time information (step S103). The stop pattern defines a speed change from a state where each reel is rotating at a constant speed until it stops, and is normally (0), low speed 1 (1), low speed 2 (2), delay (3 ), Reverse 1 (4), reverse 2 (5), top 1 (6), top 2 (7). The sub CPU 55 determines the parameter Pne with reference to a table that defines the correspondence between the parameter Pne (n = 1 to 3) and the payout time. In this example, one of Pne = 0 and 1 is selected when the payout time is t1, and one is selected from Pne = 2 to 7 when the payout time is t2. FIG. 21 shows a part of the stop pattern.

  Thereafter, the sub CPU 55 determines a provisional winning mode based on the internal lottery data ISD (step S104). In order to win a prize, it is necessary to win the prize in the internal lottery and operate the reel stop buttons 7a to 7c at a predetermined timing. For this reason, even if the internal lottery is won, the symbols constituting the winning combination are not necessarily aligned on the activated winning line. Accordingly, the winning prize indicated by the internal lottery data ISD merely indicates a prize that may be won. Therefore, when the internal lottery data ISD indicates that any prize has been won, the sub CPU 55 determines, as a temporary winning mode, a mode in which the symbols constituting the winning prize are aligned on the activated winning line. To do. For example, when a bell prize is won in the internal lottery, the display mode arranged on the winning line in which the bell symbol is validated is determined as the temporary winning mode.

  Next, the sub CPU 55 selects a stop control table based on the provisional winning mode (step S105). The stop control table is configured in the same manner as the stop table used for the above-described main reel stop control, and stores the number of offset frames in association with the symbol number. In the stop control table selection process, a stop control table capable of aligning the symbols of the provisional winning mode is selected. In addition, based on the internal lottery data ISD, you may select the stop control table which can arrange the symbol which comprises a winning combination.

  Returning to FIG. When the above-described variable mode determination process ends, the sub CPU 55 advances the process to step S62 to start variable display with reference to the selected start pattern. Before describing the processing contents of variable display using the start pattern, an outline of image processing executed by the sub CPU 55 will be described. First, the sub CPU 55 displays a set of plural kinds of symbols cyclically on the sub reels Rb1 to Rb3. The order of symbols on the sub reels is, for example, as shown in FIG. 4, and symbol numbers 1 to 21 form a set of symbols. The sub CPU 55 executes a predetermined number of writing processes to make one set of symbols. In the writing process, the sub CPU 55 reads the symbol data DG from the ROM 58 and writes it to the VRAM 90. At this time, the symbol array data is referred to. The symbol arrangement data designates the arrangement order of symbols on each sub reel. Here, from the viewpoint of facilitating the design of the program, the number of writing processes required for one cycle of the symbol should be set to coincide with the number of steps of one rotation of the main reel (the number of steps of the stepping motor). ,preferable. For this reason, in this embodiment, a set of symbols is cycled through 420 writing processes.

  Various data formats can be employed as the symbol data DG, but in this example, a bitmap format is employed. In this case, one symbol is represented by vertical X dots and horizontal Y dots. The number of dots to be moved in one writing process varies depending on the rotation direction of the sub reel. This is because the number of vertical and horizontal dots is different. For this reason, the ROM 58 stores a moving dot number table (moving dot number storage means) that stores the rotation direction and the moving dot number in association with each other. The sub CPU 55 refers to the moving dot number table. The number of dots to be moved is acquired by one writing process. In this example, the sub reels are rotated in the vertical direction and the horizontal direction. However, by using the moving dot number table, the processing can be made common and the processing load of the sub CPU 55 can be reduced.

  As described above, the amount of movement of the symbol by one writing process is fixed depending on the number of moving dots, but the sub CPU 55 determines the rotation speed of the sub reel, that is, the symbol moving speed, as the time interval of the writing process. It is adjusted by changing. The time interval of the writing process is determined by the number of interrupt signals generated at a predetermined time interval (hereinafter referred to as interrupt count). In this example, the ROM 58 stores a processing data table storing a plurality of sets (processing data) of the number of interrupts necessary to execute one writing process and the number of writing processes repeatedly executed with the number of interrupts. Has been. The sub CPU 55 refers to the processing data table and changes the rotation speed of the sub reel.

  FIG. 22A shows part of the stored contents of the processing data table. For example, in the uppermost processing data shown in the figure, if the interrupt signal interval is set to 16 msec, the number of interrupts is 10 times, that is, one write process is executed at intervals of 160 msec, and the one-step design advances. Repeat 5 times. As a result, the symbol moves by a total of 5 steps. The highest speed is achieved by using the lowest processing data. This means that when the interrupt frequency is 1 time, the 1-step symbol is advanced at an interval of 16 msec. The rotational speed can be gradually increased by sequentially using the uppermost processing data to the lowermost processing data. With such a data structure, the overall movement amount of the symbol is fixed (in this example, 40 steps), and the number of times of interrupt / deceleration pattern data is changed by rewriting the number of interrupts so that the total number of steps is 40 steps. It becomes possible to have.

  In the start pattern described above, a set of process data is specified by the parameter Pns, and in the stop pattern, the set of process data is also specified by the parameter Pne. That is, the parameters Pns and Pne function as an index for designating a set of processing data as shown in FIGS.

  In the process of step S62 shown in FIG. 15, the sub CPU 55 executes the writing process according to the set of process data specified by the parameters P1s, P2s, and P3s of the selected start pattern. As a result, the sub reels displayed on the image display device 91 start to rotate. The trigger for the rotation is acquisition of game information such as internal lottery data. That is, in this example, rotation is started when the sub CPU 55 detects game information transmitted from the main CPU 31. Here, the internal lottery data is based on the operation timing of the start lever 6 and is also information indicating the start of rotation of the main reel because the main reel rotates with this. Therefore, the sub CPU 55 rotates the sub reel with the rotation of the main reel.

  Next, the sub CPU 55 determines whether or not P1t = 0 (step S63). If P1t = 0, it means that the sub left reel Rb1 is operated in conjunction with the main left reel Ra1. If the determination in step S63 is affirmative, the sub CPU 55 determines whether the left stop information acquisition flag is “1”, that is, whether the left reel stop button 7a has been operated (step S63). S64). When the left stop information acquisition flag is “1”, the variable display is stopped with the selected stop pattern (step S65). In this case, the sub CPU 55 executes the writing process according to the set of process data specified by the parameter P1e.

  On the other hand, when it is determined that the condition of step S63 is affirmed, it is determined whether or not the set constant speed time has been reached (step S66). Specifically, the sub CPU 55 starts the time counting process from the end of the start pattern, and determines whether or not the measured value is equal to or longer than the constant speed time. When the constant speed time is reached, the variable display is stopped with the selected stop pattern (step S67).

  Next, steps S68 to S72 are processing for the middle reel Rb2, and steps S73 to S77 are processing for the right reel Rb3, except that the processing target is the left reel Rb1. Since it is the same as the process up to step S67, the description is omitted. Thereafter, the sub CPU 55 determines whether or not the winning information acquisition flag is “1” (step S78). If the winning information acquisition flag is not “1”, that is, if all the main reels are not stopped, the sub CPU 55 returns the process to step S63 and repeatedly executes steps S63 to S78. When the winning information acquisition flag becomes “1”, the process proceeds to step S79 shown in FIG.

  In the process of step S79, the sub CPU 55 compares the winning mode and the temporary winning mode (step S79), and determines whether or not they match (step S80). When the two match, the winning mode temporarily determined by the sub CPU 55 matches the winning mode of the main reel. For example, when the Bell prize is won internally, the provisional winning mode is determined based on the internal lottery data ISD transmitted from the main CPU 31, and when winning information indicating that the Bell prize is won is received, step S80 is performed. A determination is made to affirm the above condition. If it is determined that the condition of step S80 is affirmed, various flags are cleared and the one subgame is ended (step S91).

  On the other hand, if it is determined that the condition of step S80 is negative, the sub CPU 55 advances the process to step S81 so that the main reel winning mode matches the sub reel winning mode based on the winning information. Next, the sub reel winning mode is determined (step S81), and the stop control table is selected (step S82).

  Next, the sub CPU 55 determines whether or not the rotation of the sub reel has already been stopped (step S83). If the rotation of the sub reels has not stopped, the sub CPU 55 determines a stop pattern (step S84), and stops variable display with the selected stop pattern (step S85). At this time, the stop position of the sub reel is controlled so as to coincide with the winning mode of the main reel.

  If it is determined to deny the condition of step S83, the rotation of the sub reel has already stopped. In this case, the sub CPU 55 determines the sub reel to be most varied (step 86). Specifically, among the three sub-reels Rb1, Rb2, and Rb3, a sub-reel that does not match the winning mode of the main reel is specified, and this is set as a subject of re-variation.

  Thereafter, the sub CPU 55 determines the start pattern Pns (step S87), and then determines the stop pattern Pne (step S88). Further, the sub CPU 55 resumes variable display according to the selected start pattern Pns (step S89), and executes variable display stop according to the selected stop pattern Pne (step S90). At this time, the stop position of the sub reel is controlled so as to coincide with the winning mode of the main reel.

  As described above, in the present embodiment, in the sub-reel stop process, when the winning combination indicated by the internal lottery data ISD is set as the stop position target and the temporary winning mode and the actual winning mode are different, Since the sub reels are restarted so as to match, the display mode can be consistent. If the provisional winning mode matches the actual winning mode, the sub-reel does not have to be restarted, and the image display mode can be controlled so that the predetermined winning mode is achieved only when winning in the internal lottery. Therefore, the processing load can be reduced.

<2. Second Embodiment>
The slot machine according to the second embodiment is configured in the same manner as the slot machine according to the first embodiment, except that when a predetermined condition is satisfied, the specific symbol displayed on the sub reel is changed depending on the gaming state. .

  In this slot machine, the ROM 58 stores a plurality of symbol data for a specific type of symbol. In this example, the bonus symbol “7” has a plurality of variations. A specific aspect of the variation can be given depending on the size, color, and shape. FIG. 23 schematically shows the symbol change. In this example, it is assumed that symbols are displayed in the order of “A1”, “c”, “b”, “e”, “d”, “A2”,. In the second gaming state in which the BB prize is won internally, the symbol “A2” is displayed instead of “A1”, and in the third gaming state during the super big bonus, “A3” is displayed instead of “A1”. The design of is to be displayed. FIG. 24 shows an example of two sets of symbols.

  Since the gaming state is determined by at least one of the internal lottery probability and the stop control method, the player is notified that the internal lottery probability or the stop control method has been changed by changing a specific symbol according to the gaming state. be able to.

  Specifically, a symbol selection table storing the relationship between the gaming state and symbol data to be read out is stored in the ROM 58, and the sub CPU 55 identifies symbol data to be read out with reference to the symbol selection table. The specified symbol data is read from the ROM 58.

  As described above, the internal lottery is executed based on the operation timing of the start lever 6, and the sub reel starts variable display after the start lever 6 is operated. If the gaming state before the operation of the start lever 6 is the first gaming state and the BB prize is won in the internal lottery, the gaming state shifts from the first gaming state to the second gaming state from that point. Here, it is assumed that the specific symbol (in this example, “7”) is displayed on the sub reel. In this case, the symbol data may be switched while the sub reel is stopped, but the symbol may be changed when the scroll of the sub reel is started and the specific symbol disappears from the screen and appears again. Alternatively, the symbol data may be switched when the sub reel starts to rotate.

<3. Third Embodiment>
The slot machine according to the third embodiment is configured in the same manner as the slot machine according to the first embodiment except that, when a predetermined condition is satisfied, the symbol arrangement is switched for at least one sub reel among the plurality of sub reels. ing.

  As described above, the sub CPU 55 refers to the symbol arrangement data, specifies the reading order of the symbol data stored in the ROM 58, and writes the symbol data read in accordance with the specified order to the VRAM 90, thereby sub-reels Rb1 to Rb1. Rb3 is displayed. Therefore, by changing the symbol arrangement data, the arrangement of symbols displayed on each of the sub reels Rb1 to Rb3 can be changed.

  In this example, a plurality of symbol arrangement data is stored in the ROM 58 for at least one sub reel, and the sub CPU 55 selects one symbol arrangement data from the plurality of symbol arrangement data according to a predetermined symbol arrangement selection rule. Then, according to the selected symbol arrangement data, the symbol data is read from the ROM 58 and written into the VRAM 90. Each symbol arrangement data is associated with each stop control table, and the sub CPU 55 refers to the stop control table associated with the selected symbol arrangement data to execute sub reel stop control.

  For example, the first symbol array data and the second symbol array data are stored in the ROM 58 as the symbol array data corresponding to the left sub reel Rb1, and the first symbol array data indicates the symbol array of the left reel Rb1 shown in FIG. The second symbol array data may be one in which “7” is continuously arranged in symbol numbers 1 to 3. In this case, the sub CPU 55 refers to the gaming state information and selects the first symbol arrangement data when the gaming state information indicates the first gaming state (the normal game: the BB prize is not selected in the internal lottery). When the game state information indicates the second game state (internal winning in the BB prize), the second symbol array data may be selected. Further, the sub CPU 55 selects a stop control table corresponding to the selected symbol arrangement data. In this case, as shown in FIG. 25A, for the left reel Rb1, the symbol array A displayed based on the first symbol array data and the symbol array B displayed based on the second symbol array data are It is possible to switch. Thereby, in the second gaming state, so-called eye-opening is facilitated, and it is possible to indicate to the player that the gaming state has changed.

  Further, the three reel arrangements may be changed with reference to the game state information. For example, as shown in FIG. 25 (B), in the first gaming state, the symbol arrangement of the left / middle / right reels is in the order of “A”, “B”, “C”, and in the second gaming state, The symbol arrangement of the left / middle / right reels may be in the order of “B”, “A”, and “C”. Furthermore, four types of symbol arrangement data may be prepared and the symbol arrangement may be switched according to the gaming state. For example, as shown in FIG. 25 (C), in the first gaming state, the symbol arrangement of the left / middle / right reels is in the order of “A”, “B”, “C”, and in the second gaming state, the left -The symbol arrangement of the middle and right reels may be in the order of "B", "C", and "D". In these cases, the sub CPU 55 may change the symbol arrangement with reference to a table in which the relationship between the game state information, the symbol arrangement data, and the stop control table is associated.

<4. Fourth Embodiment>
The slot machine of the fourth embodiment is configured in the same manner as the slot machines of the first to third embodiments described above except that the background (color / design) of the sub reel is changed when a predetermined condition is satisfied. Has been.

  The slot machine of the fourth embodiment stores a plurality of band data (background data) indicating a background image in the ROM 58. FIG. 26 shows an example of the contents stored in the ROM 58. In this example, band data 1 to band data 4 are stored in four storage areas. Since the background image is obtained by repeating an image of a certain unit, it is not necessary to store all the display areas of each sub-reel as band data, and indicates the background image of the minimum area as a repeating unit. It is preferable from the viewpoint of saving the storage capacity of the ROM 58.

  The sub CPU 55 refers to the setting table, obtains an address corresponding to the gaming state indicated by the gaming state information, reads the band data from the address, synthesizes the read band data and symbol data, and writes it in the VRAM 90 . Here, the setting table stores a game state, display parameters, symbol arrangement data, and band data in association with each other. FIG. 27 shows an example of the stored contents of the setting table. The setting table is stored in the ROM 58. For example, when the gaming state is “A”, the address as position information for designating the storage area of the storage means is “2000H”, and the sub CPU 55 reads the band data 1 from this storage area. Thereby, for example, as shown in FIG. 28, the background of the middle subrule Rb2 can be switched according to the gaming state.

  Alternatively, common data may be stored in the ROM 58 as sub-reel band data, and the background may be switched according to the gaming state with reference to a lookup table. In the lookup table, input gradation values and output gradation values are stored in association with each other. FIG. 29 shows a background symbol changing process using a lookup table. In this example, the band data is composed of RGB color data, and each color data represents 0 to 31 gradations. The ROM 58 stores lookup tables LUT1 to LUT4 in association with the gaming state, and each lookup table LUT1 to LUT4 is associated with 0 to 32 gradations and 0 to 256 gradations. It is remembered. The sub CPU 55 selects a lookup table based on the gaming state indicated by the gaming state information, converts the band data using the selected lookup table, synthesizes the converted band data and symbol data, and writes the synthesized data to the VRAM 90. . Thereby, the storage capacity of the band data can be reduced.

<5. Fifth Embodiment>
The slot machine of the fifth embodiment is configured in the same manner as the slot machines of the first to fourth embodiments described above except that the number of sub reels is switched when a predetermined condition is satisfied.

  Specifically, as shown in FIG. 30, the three sub reels and the nine sub reels are switched. In this case, it is preferable to switch the display mode according to the gaming state and the result of the internal lottery. In the following description, three sub reels are referred to as normal reels, and nine sub reels are referred to as multi reels.

  In this case, the 9-divided multi-reel symbol arrangement is displayed in conjunction with the upper, interrupted, and lower levels so that the upper symbol is delayed by one frame from the middle symbol. FIG. 31 shows the order of symbols displayed on the multi reels A1 to A3. When the symbols are moved and displayed in the direction from A1 to A3, the upper symbols (A1, B1, C1) are moved downward by one step, and then the middle symbols (A2, B2, C2) are moved downward by one step. Similarly, the lower symbol (A3, B3, C3) is then moved downward by one step. A1 → A2 → A3 → B1 → B2 → B3 → C1 → C2 → C3 may be used.

  In order to stop the display, usually the three stages are linked to stop display, but sometimes only the symbols on the effective winning line (which can win a prize) will not stop even if the stop operation is performed. 7 is confirmed on the winning line, and then the upper and lower symbols are re-varied so as to match the regular symbol arrangement and stopped. For example, as shown in FIG. 32, when the reel stop button 7a is operated while the multi-reels A1 to A3 are rotating, the reels A1 and A3 are stopped, the rotation of the reel A2 is continued, and then the reel A2 is stopped. Let Then, the reel A1 and the reel A3 are changed again and finally stopped.

  In such multi-reel display control, the sub CPU 55 selectively executes linked control in which the upper, middle, and lower are linked and non-linked control in which at least one level is not linked to other levels. Then, the two controls are switched under a predetermined condition. Here, the predetermined condition may be, for example, the elapse of a predetermined time from the rotation start instruction, detection of a stop operation corresponding to the reel, or detection of a stop operation not corresponding to the reel.

<6. Sixth Embodiment>
The slot machine of the sixth embodiment is configured in the same manner as the slot machines of the first to fifth embodiments described above, except that when a predetermined condition is satisfied, the display is switched from the sub reel display to the feature game. . A feature game is an animation whose game result has already been determined.

  The feature game is, for example, a roulette game, and any game may be used as long as a result of two or more values is obtained at the end of the game. For example, when winning a BB prize by operating the player's reel stop buttons 7a to 7c, the main CPU 31 controls each part so as not to accept a medal payout, a BET button operation, or a start lever operation for a predetermined time. To do. Then, the sub CPU 55 causes the image display device 91 to display the feature game within a predetermined period. At this time, the start lever and the reel stop button are caused to function as operation members for the feature game. In addition to the start of the BB game, a feature game may be used to select the type of super BB and normal BB.

  In addition, the feature game can be used to determine the AT mode when applied to an AT game, and when applied to a stock game, the release of stock is triggered by a winning of a predetermined role. Notification of the pressing order of the reel stop button for winning a prize may be performed in a feature game.
