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 pushes down the start lever, all the reels rotate at the same time, and each reel stops when the player pushes down each reel stop button. Of the combinations of symbols aligned on the winning line with the reels stopped, the combination of symbols that provide a game value is called a combination. When a combination of symbols constituting a winning combination is arranged on an effective winning line, a winning is achieved, and the player can acquire the number of medals corresponding to the winning winning combination. That is, when the state in which the reels are stopped is a state (predetermined state) that is a combination of symbols constituting a combination, a combination is won, and a game value corresponding to the winning combination is provided.

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

  In the second step, the stop position of the reel is controlled according to 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 a symbol constituting a certain role approaches a valid winning line, the reel stop timing is delayed, and Control is performed so that the symbols constituting the winning combination do not stop on the activated pay line. On the other hand, if the prize group which is an internal lottery is won, even if the operation timing of the reel stop button is slightly earlier, the drawing control is performed so that the symbols constituting the combination corresponding to the prize group stop on the winning line. You. However, if the operation timing of the reel stop button is greatly shifted, no prize will be won. In other words, in order for the player to obtain a prize, it is necessary to obtain a prize of a certain prize group by an internal lottery and to align the winning combination of the prize group on an effective prize line.

  By the way, a certain kind of slot machine includes a sub effect device in addition to a main reel. This effect device is composed of three reels or a liquid crystal display device or the like. For example, Patent Literature 1 discloses a slot machine including a variable display unit configured by reels and an image display unit as a rendering device, and interlocking changes in symbols of both. Furthermore, in this slot machine, by arranging the image display unit large in the center of the housing and arranging the variable display unit small in the periphery, it is easy for the player to visually recognize the effect displayed on the image display unit. are doing.

JP-A-2002-793 (claim 1, abstract)

  However, in the conventional slot machine, the display of the main variable display section and the display of the sub image display section are variably displayed in conjunction with each other, and when the player operates the reel stop button, both are stopped in conjunction with each other. Therefore, the display on the image display unit cannot be continued after the variable display on the main variable display unit stops. For this reason, there was a limit to elaborate production.

  In addition, in the conventional slot machine, the stop mode of each reel winning a combination is provided on condition that the same type of symbols are aligned. Therefore, the sub image display section is arranged in the center, and the main variable display section is provided. Even if is arranged in the peripheral portion, the player can know the result of the game by seeing the variable display portion at a glance. For this reason, there is a problem that no matter what effect the sub image display unit performs, the effect is interesting.

  In addition, if a player wins any role, a medal corresponding to the role will be paid out, but since the medal is paid out in conjunction with the stoppage of the symbol on the main variable display section, the main symbol stoppage is performed. After that, there is a problem that no matter how the effect is produced on the sub-image display unit, it is not interesting.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a slot machine that enhances the appeal of the effect.

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

  The slot machine according to the present invention includes a first display unit (10A) having main reels (Ra1, Ra2, Ra3), a second display unit (10B) capable of changing a display mode, and the main reels (Ra1, Ra2, Ra3). A first sensor (47A, 48A, 49A) and a second sensor that respectively output a first detection signal (47a, 48a, 49a) and a second detection signal (47c, 48c, 49c) according to the rotation of Ra2, Ra3) (47C, 48C, 49C) and first control means (31) for controlling rotation of the main reels (Ra1, Ra2, Ra3) based on the first detection signals (47a, 48a, 49a); A second control means (55) for controlling the variable display of the second display means (10B) based on the second detection signal (47c, 48c, 49c), thereby providing the above-described problem. Resolve.

  According to this slot machine, the rotation of the main reel is detected by the first sensor and the second sensor, and the rotation of the main reel is controlled based on the first detection signal. Control can be performed based on the detection signal. That is, since the rotation of the main reel is detected by the second sensor independent of the rotation control of the main reel, it is possible to provide a variety of display modes of the second display means. In the present invention, the number of main reels may be singular or plural.

Another slot machine according to the present invention includes a main reel plurality of symbols are displayed (Ra1, Ra2, Ra3) first display means having a (10A), a plurality of symbols of the variable display capable display column output a second display means (10B), and start operation means for outputting a start instruction signal in response to the player's start operation (6), stop instruction signal in response to the player's stop operation (44a, 45a, 46a) and Stop operation means (7a, 7b, 7c) for controlling the first display means (10A) to start the rotation of the main reel upon detecting the start instruction signal, and control the stop instruction signal (44a, 45a, 46a) and a first control means (31) for controlling the first display means (10A) so as to stop the rotation of the main reel. Nriru a first process of the display columns in the same direction as the rotation of the (Ra1, Ra2, Ra3) controls the second display means so as to variably display, the direction of rotation of said main reel (Ra1, Ra2, Ra3) The above-mentioned problem is solved by providing a second control means (55) for controlling the second display means so as to variably display the display row in a direction opposite to the above.

According to this invention, since the second control means selectively executes the first processing and the second processing, the second display means displays a variable display irrelevant to the rotation of the main reel and a variable display irrelevant to the rotation of the main reel. It can be performed selectively. In particular, since the second processing is not related to the rotation of the main reel, a variety of effects rich in taste can be provided. Here, the variable display according to the rotation of the main reel means that the display of the second display means is changed in association with the rotation of the main reel. That is, the first process depends on the rotation of the main reel in some form. However, the second control means need not always detect the rotation of the main reel using the detection means, but it is sufficient if the second control means indirectly detects the rotation of the main reel. For example, the period from when the start instruction signal of the start operation means instructs the start operation to when the output signal of the stop operation means instructs the stop operation is a period in which the main reel is rotating. Therefore, the second control means may execute a predetermined process in the period, and may execute a process different from the predetermined process after the period. The second control means may selectively switch the display control of the second display means before and after the output signal of the stop operation means instructs the stop operation . Ku it and example, start instruction signal and stop instruction signals, may be directly supplied to the second control unit, or may be supplied to the second control unit via the first control means. In this case, the first control means may detect the start instruction signal and the stop instruction signal, and supply the detection result as a command to the second control means.

Another slot machine according to the present invention is capable of displaying a plurality of symbols, a first display means (10A) having a main reel (Ra1, Ra2, Ra3) on which a plurality of symbols are displayed, and a display window (4A). Second display means (10B) having an appropriate display sequence, start operation means (6) for outputting a start instruction signal in response to a player's start operation, and stop instruction signals (44a, 45a) in response to a player's stop operation. , 46a) and the first display means (10A) to detect the start instruction signal and start the rotation of the main reels (Ra1, Ra2, Ra3). ), And controls the first display means (10A) to stop the rotation of the main reels (Ra1, Ra2, Ra3) by detecting the stop instruction signals (44a, 45a, 46a). A first control means (31) which, during rotation of said main reel, said main reel (Ra1, Ra2, Ra3) corresponds to the display mode of the symbols displayed on the display window (4A) by rotating Processing for changing the display mode of the second display means (10B) as described above, and the second display means (10B) so that the display mode is different from the display mode of the symbols displayed on the display window (4A). And a second control means (55) for selectively executing the second process of changing the display mode of (5).

  According to the present invention, the second control means selectively executes the first processing and the second processing, so that the second display means corresponds to the display mode of the symbol displayed on the display window of the main reel. As described above, the display mode of the second display unit can be changed, or the display mode of the second display unit can be changed so as to be different from the display mode of the symbol displayed on the display window. In particular, since the second process has a display mode different from the display mode of the main reel, it is possible to perform various effects rich in taste.

  Here, the display mode of the symbol displayed in the display window means the behavior of the symbol displayed in the display window. For example, the symbol moves from top to bottom, and the symbol moves from bottom to top. Symbol movement direction such as reverse rotation (main reel rotation direction), symbol movement speed (main reel rotation speed), symbol movement acceleration (main reel rotation acceleration), whether the symbol is stopped or moved, the symbol is the same speed Corresponds to whether the camera is moving or frame-by-frame. To change the display mode of the second display means so as to correspond to the display mode of the symbol means to change the display mode of the display column of the second display means in correspondence with the behavior of the symbol displayed in the display window. Means that. For example, if the main reel is rotating forward, the symbol displayed in the display column is displayed to move from top to bottom, and if the rotation of the main reel is started and accelerated, the display column Start the movement of the symbols to be displayed, gradually increase the moving speed, if the main reel is rotating, move the symbols to be displayed in the display column, if the main reel is rotating at a constant speed This means that the symbols displayed in the display column are moved at a constant speed. However, it is not necessary for all of the symbol behaviors such as normal rotation / reverse rotation, speed, acceleration, stop / movement, normal / frame feed, to correspond, and at least one of them is sufficient.

The speed is To match the rotational speed of the main reel indicated by the velocity information, wherein the pattern image data (DG) said display storage means reads out from said image memory means (58) based on the first velocity information (90) the it by the writing to the updating means for updating the storage contents of the display memory means as a variable display speed closer to the first speed information (90) (55) is preferably provided with a. In this case, the variable display speed of the image displayed on the electric image display device can be adjusted so as to follow the mechanical rotation speed of the main reel.

  Further, the first speed detecting means (47C to 49C, 55) outputs the first detection pulse (47c, 48c, 49c) at a timing when the reference point of the main reel (Ra1, Ra2, Ra3) passes a predetermined position. The first sensor (47C, 48C, 49C) generated, a measuring unit (55) for measuring a time interval between the first detection pulses (47c, 48c, 49c), and a measurement result of the measuring unit (55). And first speed information generating means (55) for generating the first speed information based on the first speed information. When the main reel rotates, it passes through the reference point in synchronization with the rotation, so that the rotation speed of the main reel can be detected by measuring the time interval between the first detection pulses.

  More specifically, the first sensors (47A, 48A, 49A) which generate the first detection pulses (47a, 48a, 49a) at the timing when the reference points of the main reels (Ra1, Ra2, Ra3) pass through predetermined positions. ), Wherein the first control means (31) detects the first detection pulse (47a, 48a, 49a) and generates a detection signal, and the detection signal generation means (31) 2 output means (31, 37) for outputting to the control means (55), wherein the second control means (55) includes an input means (56) for inputting the detection signal, and a time for inputting the detection signal.

In this case, for example, while the main CPU controlling the main reel generates the detection signal, the sub CPU can control the second display means, so that the processing can be rationally distributed. It becomes possible.

Here, the first speed information generating means (55) generates the first speed information based on an average value obtained by calculating an average of the time intervals measured by the measuring means (55) . Is preferred. Since the main reel has a mechanical configuration, the rotation speed of the reel includes some error. In addition, random signal delay or the like may occur due to input / output of the transmission path. According to the present invention, since the first speed information is generated based on the average value of the measurement results, the rotation speed of the main reel can be accurately detected particularly when the main reel is rotating at a constant speed.

The arrangement of the symbols in the display column is associated with different types of symbols for each main reel. For example, the symbols on the main reel are composed of “1”, “2”, and “3”, the symbols on the display column are composed of “A”, “B”, and “C”, and the number of main reels is It is assumed to be “3”. In this case, “the layout of the symbols in the display column is associated with a different type of symbol for each main reel” means, for example, “1” in the set of the first main reel and the display column. "A", "2" and "B", and "3" and "C" correspond to each other. In the pair of the second main reel and the display column, "1" and "B" and "2" “C”, “3”, and “A” correspond to each other. In the third main reel and display column pair, “1” and “C”, “2” and “A”, and “3” It means that "B" corresponds.

  When such association is performed, when the same type of symbols are arranged in a state where each display column is stopped, different types of symbols are arranged on each main reel. Then, the arrangement of the symbols to be paid out is of the same type on the second display means and different on the first display means, so that the player's interest can be attracted to the second display means. As described above, since the second display means can perform various effects, the fun of the game can be greatly improved. Furthermore, in the state where the variable display of the first display means is stopped, it is not apparent at first glance that a prize has been won. Therefore, the player can enjoy the effect of the second display means performed after the variable display of the first display means is stopped. it can.

  The plurality of types of symbols displayed on the main reels (Ra1, Ra2, Ra3) are a set of figures having different numbers, a set of figures having the same shape but different colors, a set of figures having different corner shapes, and colors. It is preferable that any one of a set of figures having the same shape but different shapes, or a set of figures obtained by rotating a figure having a predetermined shape by a different angle is used. Further, it is preferable that the plurality of types of symbols displayed on each of the main reels (Ra1, Ra2, Ra3) are all different from the plurality of types of symbols displayed in each of the display columns. In these cases, it is possible to make it difficult for the player to determine whether or not a prize has been won even at a glance at the first display means, and to attract the player's interest to the second display means.

  Further, in the present invention, the slot machine includes a pachislot machine in which the first display means is constituted by mechanical reels, and also includes a video slot in which the first display means is constituted by an image display device.

  As described above, according to the present invention, it is possible to improve the attractiveness of the effect produced by the second display means.

<1-1: External Configuration of Slot Machine>
FIG. 1 is a perspective view showing an appearance of a slot machine 1 according to an embodiment of the present invention. The housing of the slot machine 1 includes a main body 2 and a front door 3 attached to the front of the main body 2. On the upper right side of the front door 3, a first display unit 10A is provided. On the other hand, a second display unit 10 </ b> B is provided at the center of the front door 3 in the middle. 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 more than the first display unit 10A. Easy to see. A first display window 4A and a second display window 4B are provided in front of the first display unit 10A and the second display unit 10B. The first display window 4A and the second display window 4B are formed of, for example, a transparent material such as an acrylic resin. On the first display window 4A and the second display window 4B, three pay lines L1 to L5 are provided horizontally and two diagonally.

  In addition, an auxiliary display unit 11 is provided on the left side of the second display window 4B. The auxiliary display unit 11 includes five LEDs corresponding to the respective pay lines L1 to L5. Note that the auxiliary display unit 11 may be provided around the first display window 4A. When the player inserts medals or performs a betting operation described later, the number of winning lines L1 to L5 according to the number of bets becomes valid. In this slot machine 1, the pay line L1 is valid when the number of bets is one, the pay lines L1 to L3 are valid when the number of bets is two, and the pay lines L1 to L3 when the number of bets is three. L5 becomes effective. Each LED constituting the auxiliary display unit 11 is turned on when the corresponding pay line L1 to L5 is valid, and is turned off when the corresponding pay line L1 to L5 is invalid. This allows the player to know which pay line L1 to L5 is valid.

  Inside the first display window 4A, three rows of left, middle, and right reels Ra1, Ra2, and Ra3 each having a plurality of types of symbols drawn on the outer peripheral surface thereof are rotatably provided. Inside the 4B, three rows of left, middle, and right reels Rb1, Rb2, and Rb3 each having a plurality of types of symbols drawn on each outer peripheral surface are rotatably provided. 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, while the left, middle, and right reels Rb1 and R3 as display columns are controlled. The rotation (variable display) and stop of Rb2 and Rb3 are controlled by a signal from a sub-board described later.

  FIG. 2 shows the structure of the left / center / right reels Rb1, Rb2, Rb3, and FIG. 3 shows the detailed structure of the right reel Rb3. Each of the reels Rb1 to Rb3 has an annular shape, and various symbols are printed on the surface thereof. On the back surface of the right reel Rb3, a light shielding film S for shielding light is formed except for a part. In the portion where the light-shielding film S is formed, light is not transmitted even when light is irradiated from the back side. On the other hand, in each symbol portion, the light-shielding film S is not formed, and an uneven member P for scattering light is formed on the back surface of the right reel Rb3. In addition, in each design part, the reel itself is white and translucent. In the example shown in FIG. 3, the uneven member P is formed inside the contour portion of the symbol "7".

  On the inner peripheral surface side of the right reel Rb3, a lighting unit 670 for the right reel is arranged. The right reel lighting unit 670 includes upper, middle, and lower shades separated by light shielding walls. 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-blocking piece 491 is provided on a part of the right reel Rb3 so as to protrude from the reel body, and crosses the photo sensor 492 when the right reel Rb3 rotates. The photo sensor 492 functions as a right reel position detection sensor 49B (see FIG. 11) that detects the rotation position of the right reel Rb3. The structure of the left reel Rb1 and the center reel Rb2 and the peripheral configuration thereof are the same as the structure of the right reel Rb3 and the peripheral configuration thereof described with reference to FIG. 3, and the rotational position of the left reel Rb1 and the center reel Rb2 is also the same. Are provided. Left / middle reel rotation position detection sensors 47B and 48B are provided. Output signals of these sensors are sent to the sub-board.

  The left, middle, and right reels Ra1, Ra2, and Ra3 of the first display unit 10A are configured in the same manner as the above-described second display unit 10B. However, these reels are provided with left / middle / right reel position detection sensors 47C, 48C, 49C for the sub-board in addition to left / middle / right reel position detection sensors 47A, 48A, 49A for the main board. ing. In this example, the left / middle / right reel position detection sensors 47A, 48A, 49A for the main board and the left / middle / right reel position detection sensors 47C, 48C, 49C for the sub board are provided independently. , The left / middle / right reel position detection sensors 47A, 48A and 49A may be used also for the sub-board. From these sensors, a reference point passage signal that becomes active at the timing when the light shielding piece passes through the photosensor in one rotation is generated as a detection signal.

  Returning to FIG. 1, the description will be continued. Below the second display window 4B, there is provided an operation section OP in which various operation members for the player to execute a game are arranged. The operation unit OP includes a medal insertion 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 insertion slot 5 is provided diagonally below and to the right of the second display window 4B so that medals can be inserted. When one medal is inserted, the pay line L1 is activated. When two medals are inserted, the pay lines L1 to L3 are activated. When three medals are inserted, the pay lines L1 to L5 are activated. Further, when the player inserts more than three medals, the slot machine 1 accumulates four or more medals as credits.

  The BET button 15 is provided on the lower left of the second display window 4B. The BET button 15 is used to specify the number of medals that the player bets in one game. By operating the BET button 15 by a player, a stored medal can be bet without inserting a medal from the medal insertion slot 5. Therefore, the pay lines L1 to L5 are appropriately activated according to the number of medals specified by operating the BET button 15. The relationship between the number of medals specified by the operation of the BET button 15 and the activated pay lines L1 to L5 is the same as in the case where medals are directly inserted.

  The start lever 6 is provided below the BET button 15. The start lever 6 is used by a player to instruct the start of a game. When the player pushes down the start lever 6, the left / center / right reels Ra1, Ra2, Ra3 and the left / center / right reels Rb1, Rb2, Rb3 start rotating simultaneously, and the first display unit 10A and the second display unit The symbol 10B is displayed variably.

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

  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. By operating the credit button 8 by the player, it is possible to change whether the credit is valid or invalid. In a predetermined case, medals are paid out to the player from the medal payout exit 10a and stored in the medal receiving tray 10.

<1-2: Relationship between roles and symbols>
FIG. 4 shows an example of symbols displayed on the left, center and right reels Ra1, Ra2 and Ra3 and the left, center and right reels Rb1, Rb2 and Rb3. As shown in this figure, 21 reels and 6 kinds 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 is referred to as a main reel. The left / center / right reels Rb1, Rb2, Rb3 are simply referred to as sub reels.

  FIG. 5 shows the correspondence between the symbol on the sub reel and the symbol on the main reel. As shown in this figure, a symbol with 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 roughly classified into a "role" that gives a game value and a "losing" that has no value. The winning combination refers to a predetermined combination of symbols stopped on the activated pay line in a state where the main reels as display columns are stopped. In this example, since the symbols on the main reel are associated with the symbols on the sub reels, in a state where each sub reel is stopped, a predetermined combination of symbols stopped on the activated pay line of the second display unit 10B is selected. The aspects correspond to roles.

  FIG. 6 shows the relationship between symbols and symbols on the sub reel and the main reel. In the present embodiment, a BB role, an RB role, a plum role, a bell role, a cherry role, and a replay role are adopted as roles. The arrangement of the symbols constituting the winning combination on the 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 required for the player to continue the game. In other words, the medal can be regarded as 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 from each other in a predetermined manner on the activated pay line to be bet among the plurality of pay lines L1 to L5 of the first display unit 10A. This is an aspect in which the types of symbols are arranged, and the symbols constituting the role of the sub reel are those in which the same type of symbols are arranged on the activated pay line among the plurality of pay lines L1 to L5 of the second display unit 10B. . The roles of the present embodiment include the following.

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

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

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

  5) Plum role This role is a symbol with the symbol number PN = 18, 15, 9 or 2 on the left reel Ra1, Rb1, a symbol with the symbol number PN = 18, 14, 10, 6 or 1 on the middle reel Ra2, Rb2. This is a combination of symbols of the 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-". 2 ".

  6) Cherry role In this role, the symbol of the symbol number PN = 20, 13 or 6 on the left reels Ra1 and Rb1 may be stopped at the activated one of the pay lines L1 to L5, and the stop position of the other reels Has nothing to do with. 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 is a symbol with the symbol number PN = 19, 17, 10 or 3 on the left reel Ra1, Rb1, a symbol with the symbol number PN = 19, 15, 11, 7 or 2 on the middle reel Ra2, Rb2, This is a combination of symbols of the symbol numbers PN = 20, 15, 11, 7 or 3 on 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 “7-4-4”. 1 ". Even if the replay combination is established, there is no payout of medals, but replays are possible. Replay refers to playing the game again without inserting a new medal.

  For these combinations, the game value given to the player for each combination for each game state is determined in advance. Roles with 1 to 15 payouts, roles with advantageous gaming status such as big bonuses and regular bonuses regardless of payouts with prizes, and medals with no payouts There is a role of being provided with a re-game in which a game can be performed again under the same number of medal insertion conditions without performing the game. In addition, not all of these combinations are necessarily set as prizes in all gaming states. It is also possible to establish a prize in one game state but not a prize in another game state. That is, the game value given to the player for each winning of each combination is predetermined for each game state and is not always constant.

  In this embodiment, the game value given to the player in the normal game state is as follows: 15 plums, 10 bells, and 2 cherrys are paid out, and the replay is replayable. Role.

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

  Further, when the player wins the BB combination, the gaming state shifts from the 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, in addition to the regular bonus being able to be performed up to three times, it is possible to achieve up to thirty times the game with the small winning combination in the high winning probability state. The big bonus is a gaming state that is more advantageous than the regular bonus. In the following description, the former is referred to as RB during BB, and the latter is referred to as single RB, in order to distinguish a regular bonus during the big bonus from a regular bonus that has been won independently.

<1-3: Electrical configuration of slot machine>
FIG. 7 is a block diagram showing a control device for controlling the game processing operation in the slot machine 1 and a circuit configuration including peripheral devices related to the present invention among the components forming the slot machine 1. As shown in FIG.

  The control device includes a main board 30A and a 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 except for the transmission timing control circuit 36 via a bus (not shown). The main CPU 31 executes the first control program CP1 to control each component. The first control program CP1 describes how the entire slot machine 1 operates. Therefore, 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 oscillator, generates a fixed-cycle reference clock signal CLK, and supplies this to the main CPU 31 and the sequence generation circuit 33.

  The sequence generating circuit 33 is constituted by 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 depends on the storage content of the prize group lottery table TBL1, which will be described later, and is, for example, 0 to 59999. The count data CD is constantly supplied to the main CPU 31. The main CPU 31 detects the timing at which the player has depressed the start lever 6, and generates the sampling data SD by sampling the count data CD at the timing.

  Since the player cannot know the value of the count data CD, the timing at which the start lever 6 is pressed down by the player is random. Therefore, the value of the sampling data SD is equivalent to a value obtained by sampling a certain value from random numbers. 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 operate the start lever 6 to cause the main CPU 31 to generate the sampling data SD having a desired value.

  Next, the RAM 34 functions as a work area for 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, the internal lottery data ISD or the like indicating the result of the internal lottery is stored in the RAM 34.

  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 addition to the first control program CP1. The winning symbol combination table TBL3 stores a combination of symbols of winning combinations and the number of medals to be paid out of winning combinations in association with each other.

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

  The prize group lottery table group TBL1 includes a plurality of prize group lottery tables. The main CPU 31 performs an internal lottery using the prize group lottery table selected according to the gaming state. As the 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 the figure, the prize group lottery table TBL11 stores lottery division data in first to seventh storage areas ADR1 to ADR7. The value of the lottery section data indicates the width of the lottery section corresponding to each prize group. For example, the lottery division data stored in the first storage area ADR1 corresponds to a loss, and the value is “54000”. The lottery division 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 losing.

  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 an internal register (step S2), and subsequently changes the value of the variable N to N + 1 (step S3). Thereafter, the main CPU 31 reads out the lottery division data from the N-th storage area (step S4). In the processing immediately after the initialization processing, the value of the variable N is “1”, so that the lottery division 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 division 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 equal to or larger than the reference value (step S6). The reference value is equal to the sum of the values of each lottery division 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 processing from step S3 to step S6 until the added value becomes equal to or more than the reference value. Then, when the added value becomes equal to or larger 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, the player loses, when N = 2, the replay prize, when N = 3, the cherry prize, when N = 4, the bell prize, when N = 5, the plum prize, and when N = 6, the RB prize. , N = 7, it is determined that the BB prize has been won. As a result, as shown in FIG. 8, the correspondence between the sampling data SD and the prize groups is lost when SD = 59999 to 6000, replay award when SD = 5999 to 4200, and cherry award when SD = 4199 to 3000. SD = 2999 to 1740 corresponds to the Bell prize, SD = 1799 to 900 corresponds to the Plum prize, SD = 899 to 300 corresponds to the RB prize, and SD = 299 to 0 corresponds to the BB prize.

  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 a BB prize, the second bit is an RB prize, the third bit is a bell prize, the fourth bit is a plum prize, the fifth bit is a cherry prize, and the sixth bit. Each bit is assigned a replay prize. If any prize is won by the 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 game has been won or lost, and the winning prize group.

  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. Setting the BB winning flag or the RB winning flag to “1” is called “set”, and setting it to “0” is called “clear”. The same applies to small roles. Regarding small wins, even if an internal lottery is won in a certain game, medals are not paid out unless a prize is won in the game. However, if the RB prize and the BB prize are won by an internal lottery of a certain game, the BB prize flag or the RB prize flag is not cleared even if the prize is not won in that game, and the BB prize flag or the BB prize is not cleared until the next game is won. The RB winning flag is not deleted. This is called carryover of the winning flag.

  Next, the stop table group TBL2 includes a plurality of stop tables. In each stop table, a symbol number PN displayed on the central pay line L1 and misplaced frame number data indicating the number of misplaced frames are stored in association with each other. Here, the number of shift 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 to when each of the left / middle / right reels Ra1, Ra2, Ra3 stops. Means

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

  However, in order for low-skilled players to enjoy the game, it is necessary to make the symbols easier to match to some extent, but if the result of the internal lottery is lost, it is necessary to control the rotation of the reels so that the winning combination is not realized There is. The stop table is used for controlling such reel rotation. The stop positions of the left, middle, and right reels Ra1, Ra2, Ra3 are determined with reference to a 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 types of information generated by the main CPU 31 to the sub board 30B. The information transmitted to the sub-board 30B includes the internal lottery data ISD, the effect adjustment time, the operation timing of the start lever 6, the stop symbol number, the 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 a control signal 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 insertion slot 5 and generates one output pulse for one medal. Therefore, the main CPU 31 can detect the number of inserted medals by counting the output pulses.

  The BET button sensor 42 detects an operation of the BET button 15. The start lever sensor 43 detects an operation of the start lever 6. The left / middle / right reel stop button sensors 44, 45, 46 detect operations of the left / middle / right reel stop buttons 7a, 7b, 7c, respectively, and output stop instruction signals 44a, 45a, 46a. The left, middle, and right reel position detection sensors 47, 48, and 49 detect the rotational positions of the left, middle, and right reels R1, R2, and R3, and generate reference point passing signals 47a, 48a, and 49a (detection signals). .

  The right reel position detection sensor 49A includes the photo sensor 492, an amplifier, and a comparator shown in FIGS. The photo sensor 492 includes a light emitting unit and a light receiving unit. When the light receiving section outputs a light receiving signal of a level corresponding to the amount of received light, the amplifier amplifies the light receiving signal. The comparator compares the output signal of the amplifier with a predetermined threshold to generate a reference point passage signal 49a, and outputs this as an output signal of the right reel position detection sensor 49A. When the right reel R3 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 R3 can be detected by the reference point passage signal 49a. The left / middle position detection sensors 47A and 48A have the same configuration as the right reel position detection sensor 49A.

  As main means connected to the output port 39 and supplied with various output signals, there are a medal payout mechanism 70 and left / middle / right reel drive motors 51A, 52A, 53A. The medal payout mechanism 70 includes a hopper for storing medals in the slot machine 1, a disk mechanism for discharging medals from the hopper to the medal receiver 10, a counter for counting the number of medals to be discharged, and the like, based on a control signal from the main CPU 31. Then, the specified number of medals are discharged.

  The left / middle / right reel drive motors 51A, 52A, 53A are motors for rotating the left / middle / right reels Ra1, Ra2, Ra3, respectively. In this example, they are constituted by stepping motors. Therefore, the main CPU 31 adjusts the number of pulses of each 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. The stop position can be determined accurately.

  Each of the motors 51A, 52A, and 53A is configured to make one rotation by 420 pulses. As described above, since 21 symbols are formed on each of the reels Ra1, Ra2, 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 position data MD1, MD2, MD3. The values of the position data MD1, MD2, MD3 are cleared at the timing when the reference point passing signals 47a, 48a, 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 passage signal 49a rises from a low level to a high level at time t1, the value of the position data MD3 is cleared. Time t1 is a timing at which the light shielding piece 491 shown in FIG. At this time, as for the rotational position of the right reel Ra3, the symbol (7) with the symbol number PN = 1 shown in FIG. 4 is displayed in the middle of the display window 4A. In other words, the mounting position of the light shielding piece 491 and the photo sensor 492 is determined so that the symbol is displayed in the middle of the display window 4A.

  Then, when 20 pulses are supplied to the right reel drive motor 53 as the drive signal 53a during the period from time t1 to time t2, the right reel drive motor 53 rotates the right reel Ra3 by 1/21 rotation. As a result, the symbol (2) with the symbol number PN = 2 shown in FIG. 4 is displayed in the middle of the display window 4A. Hereinafter, the symbols are sequentially displayed in the same manner, and at time t3, the right reel Ra3 makes one rotation, and the symbol (7) with the symbol number PN = 1 is displayed again. As described above, 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 display state of the symbol based on the position data MD3. Can be.

  In addition, the main CPU 31 can detect the display state of the symbols on the left reel Ra1 and the center reel Ra2, similarly to the above-described right reel Ra3, based on the position data MD1 and MD2. These points are the same for the sub-board 30B, and the sub-CPU 55 can detect the display state of the symbol based on the position data.

  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, and a RAM 59.

  The sub CPU 55 functions as a control center for controlling the sub board 30B according to the second control program CP2. At this time, the sub CPU 55 executes various lotteries. In addition, any method may be used for the lottery. For example, when the sampling data SD is received from the main board 30A and the sampling data SD takes a predetermined value, the winning may be performed. Alternatively, when a random number is generated by software, the value is sampled, and a predetermined value is obtained, the winning may be achieved.

  The data input circuit 56 is an interface that receives various types of information transmitted from the above-described data transmission circuit 37 and transfers them to the sub CPU 55. The clock generation circuit 57 generates a clock signal and supplies it to the sub CPU 55.

  The ROM 58 stores a stop data table group and a symbol arrangement table in addition to the second control program CP2. The symbol array table stores a symbol number and a symbol type in association with each sub reel. Further, the RAM 59 functions as a work area of the sub CPU 55, and stores data, flags, and the like in the middle of processing performed according to the second control program CP2.

  The left / middle / right backlights 65 to 67 are controlled to be turned on / off according to a command from the sub CPU 55. For example, when a specific prize group (for example, a bell prize) is won by an internal lottery, the pressing order of the left / middle / right reel stop buttons 7a, 7b, 7c is changed by setting the left / middle / right backlights 65 to 67 Notify using. Specifically, the backlight corresponding to the button to be pressed next is turned on, while the other backlights are turned off.

  Further, the sub-board 30B includes a sound LSI 61, a sound ROM 62, and a sound processing circuit 63. The sound ROM 62 stores sound data for generating various sound effects. The sound LSI 61 reads sound data from the sound ROM 62 at a predetermined timing based on a command from the sub CPU 55, performs predetermined processing, and outputs the processed sound data to the sound processing circuit 63. The audio processing circuit 63 generates an audio signal by DA conversion of the audio data, 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.

  The sub-board 30B includes left / middle / right drive motors 51B, 52B, 53B, left / middle / right reel position detection sensors 47B, 48B, 49B, and left / middle / right reel position detection sensors 47C, 48C, 49C. Is connected to The left / middle / right drive motors 51B, 52B, 53B are motors for rotating the respective sub reels Rb1, Rb2, Rb3. The left / middle / right reel position detection sensors 47B, 48B, 49B detect the rotation of the sub reels Rb1, Rb2, Rb3 and output reference point passage signals 47b, 48b, 49b. The left / middle / right reel position detection sensors 47C, 48C, and 49C detect rotation of the main reel and output reference point passing signals 47c, 48c, and 49c.

  By the way, in order to prevent a storage device such as a ROM or the main body of the sub-board 30B from being exchanged by impropriety, a so-called “sealing” may be applied when the case housing the sub-board 30B is fixed to the main body 2. . A sealing member having identification information such as characters and numbers is used for sealing. When removing the sub-board case from the game machine 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 arranged on a 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 the identification information is passed through the through holes 303 and 304.

  The sealing member 305 has an insertion portion 30a and a band portion 30b, and has a single band shape. The one end is inserted into the other end of the insertion portion 30a to form an annular shape, and the inserted end does not come off due to the shape 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 a “bundling band” used for bundling a plurality of electric wirings is used. The sealing member 305 is a metal such as a resin or a wire having elasticity that can be easily bent by human power, and communicates the heads of the two screws even if the directions of the through holes 303 and 305 are not aligned. be able to. In the case of resin, a plate-shaped portion for providing identification information may be integrally formed at the end of the band-shaped portion passing through the through holes 303 and 304 as shown in the figure. A metal such as a wire may be provided as long as it is provided with a plate-shaped member for providing identification information separately from the wire, or is formed integrally by forging or welding.

  Although not shown, the lower part of the sub-board case 300 has a protrusion inserted into the main body 2 and is fixed by the screws 301 and 302 above the sub-substrate case 300. It will not come off. Therefore, there is no need to screw the lower portion of the sub-board case 300.

<1-4: Overall operation of slot machine>
Next, the overall operation of the slot machine 1 will be described. FIG. 13 and FIG. 14 are flowcharts showing an operation in which 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 the detection signals from the inserted medal detection sensor 41 and the BET button sensor 42 (step S11). Proceed to step S12.

  In step S12, 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 performs a process of prohibiting a bet operation (step S13). When the bet operation is prohibited, even if the player inserts medals or operates the BET button 15, the reception is refused until the prohibition is released.

  Next, the main CPU 31 sets a prize group lottery table according to the game mode according to the first control program CP1 (step S14). 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, the BB flag, and the like stored in the RAM 34, specifies 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. .

  Next, the main CPU 31 executes an internal lottery process using the prize group lottery table TBL1 set in step S14 (step S15), and sets a winning flag indicating a winning prize group or a loss (step S16). The internal lottery process and the setting of the winning flag are performed in the following procedure. First, the main CPU 31 acquires the sampling data SD by sampling the count data CD at the timing when the detection signal of the start lever sensor 43 becomes active. Second, the main CPU 31 refers to the prize group lottery table and generates internal lottery data ISD. For example, if the value of the sampling data SD is “150” using the prize group lottery table TBL11 shown in FIG. 8, the internal lottery data ISD indicates the winning of the BB prize. In this case, the main CPU 31 sets a winning flag in the first bit of the internal lottery data ISD in the internal lottery data ISD. Thereafter, the main CPU 31 transmits a winning flag (internal lottery data ISD) to the sub-board 30B (step S17).

  Next, the main CPU 31 executes an effect adjustment time setting process (step S18). FIG. 15 is a flowchart showing the contents of the effect adjustment time setting process. The main CPU 31 sequentially determines, based on the internal lottery data ISD, whether or not a plum prize, a bell prize, a cherry prize, a JAC prize, or a RB during BB has been won (steps S50 to S53, S59). If these prize groups have been won in the internal lottery, the effect adjustment time is set to "0" (steps S54 to S57).

  On the other hand, if none of the prize groups described above has been won in the internal lottery, the main CPU 31 determines whether it is a single RB win, a BB win, or a loss (steps S58, S60, S61), and effects. The adjustment time is determined by lottery (steps S62 to S65). As the effect adjustment time, a plurality of times such as 5 seconds, 10 seconds, and 20 seconds are predetermined, and the main CPU 31 generates effect adjustment time information indicating the effect adjustment time selected as the lottery result. I do. Here, the effect adjustment time information may directly indicate the effect adjustment time, or may indicate which effect adjustment time is selected from predetermined effect adjustment times. Is also good. In the latter mode, the effect adjustment time is commanded. For example, 5 seconds is associated with T1, 10 seconds is associated with T2, and 20 seconds is associated with T3, and T1, T2, or T3 is commanded. It is generated as adjustment time information. In this case, it is preferable that the correspondence between the command type (T1, T2, T3) and the effect adjustment time (5 seconds, 10 seconds, 20 seconds) be held in the memory on both the main board 30A and the sub board 30B. .

  When the effect adjustment time is determined in this way, the main CPU 31 advances the process to step S19 shown in FIG. 13 and transmits effect adjustment time information indicating the effect adjustment time to the sub-board 30B (step S19).

  Next, the CPU 31 selects a reel stop data group based on the internal lottery data ISD (step S20). For example, it is determined whether or not the game is in the BB game based on the BB flag indicating that the game is in the BB game. If the result of the determination is negative, the main CPU 31 determines whether the game is in the stop table group TBL2. If the determination result is affirmative while the normal stop table is selected, the main CPU 31 selects the BB stop table from the stop table group TBL2.

  Next, the main CPU 31 executes a reel rotation process (step S21). Specifically, the drive signals 51a to 53a are activated. Then, the rotation axes of the left / middle / right reel drive motors 51A to 53A start rotating, and the main reels Ra1 to Ra3 rotate accordingly.

  Thereafter, the main CPU 31 executes a reel rotation stop process (step S22). FIG. 16 is a flowchart showing the contents of the reel rotation stop processing. First, the main CPU 31 determines whether or not the rotation speed of each main reel has reached a specified speed (step S70). Specifically, the main CPU 31 detects the frequencies of the detection signals 47a to 49a, and executes the determination in step S70 based on whether or not the detected frequency has reached a frequency corresponding to the specified speed.

  When the rotation speed of the main reel reaches the specified speed, the main CPU 31 determines whether or not the first button stop operation has been performed based on the stop instruction signals 44a to 46a (step S71).

  When the first stop operation of the reel stop button is detected, the main CPU 31 acquires the stop button numbers (button types) of the currently pressed reel stop buttons 7a to 7c (step S72), and immediately after the stop operation. The symbol number PN is obtained (step S73). Specifically, the main CPU 31 detects the timing at which each of the reel stop buttons 7a, 7b, 7c is depressed based on the stop instruction signals 44a to 46a from each of the reel stop button sensors 44 to 46, and detects the symbol number at that timing. Get PN. In this example, a stop button number "1" is assigned to the reel stop button 7a, a stop button number "2" is assigned to the reel stop button 7b, and a stop button number "3" is assigned to the reel stop button 7c.

  Next, the main CPU 31 limits the usable stop data table group based on the internal lottery data ISD, the stop button number, and the like from the stop data table group selected in step S20 (step S74), and stops. The combination of the stop data tables according to the operation order is specified (step S75). Thereafter, the main CPU 31 specifies a combination of stop data tables to be used for the first stop (step S76), and when there are a plurality of combinations, determines a stop table to be used for the first stop by lottery or the like. (Step S77).

  Next, the main CPU 31 obtains the number of advance frames by referring to the determined stop table (step S78), and calculates the stop symbol number from the pressed symbol number and the number of advance frames (step S79). The stop symbol number is a symbol number when the main reel is stopped. Thereafter, the main CPU 31 transmits the button number and the stop symbol number to the sub-board 30B (step S80), and stops the main reel for which the stop operation has been performed based on the stop symbol number (step S81).

  Next, the main CPU 31 determines whether or not a second button stop operation has been performed based on the stop instruction signals 44a to 46a (step S82). Execute (step S83). Thereafter, the main CPU 31 determines whether or not a third button stop operation has been performed based on the stop instruction signals 44a to 46a (step S84). If the third button stop operation has been performed, the third stop processing is performed. Execute (step S85). The second stop processing and the third stop processing are the same as the processing from step S72 to step S81 described above, and thus the description is omitted. Then, the main CPU 31 generates a winning flag based on the stop symbol numbers determined by the first to third stop operations (step S86). The winning flag functions as winning information indicating a winning combination or a loss. As described above, in the reel rotation stop processing, in each stop operation from the beginning to the end, information for identifying the operated reel stop button (stop button number) and information for indicating a stop symbol (stop symbol number) are stored in the sub-board 30B. Sent to Here, the information for identifying the reel stop button corresponds to stop operation information indicating a stop operation of the main reel.

  The description returns to FIG. Upon completion of the reel rotation processing, the main CPU 31 determines whether or not a replay prize has been won (step S23). When the player wins the replay prize, the same prize line activated in the previous game is automatically activated without performing a bet operation. Therefore, when the player has won the replay prize, the main CPU 31 clears the replay winning flag (step S24), and thereafter returns the process to step S12.

  On the other hand, if the replay prize has not been won, the main CPU 31 sets the effect adjustment time determined in step S18 in the timer, and starts the timer subtraction process (step S25). The main CPU 31 determines whether or not the timer value has become "0" (step S26), and when the timer value has become "0", executes a payout process described later. During the period from when the rotation of the main reel is stopped until the effect adjustment time elapses, the payout of medals is prohibited even if the player has won any role, and the medal payout is executed after the effect adjustment time elapses. You. The main CPU 31 executing steps S25 and S26 functions as an adjusting unit that adjusts the payout start time of medals based on the effect adjustment time so that medals are paid out after the rotation of the sub reels finally stops. In this example, the payout start time is adjusted based on the effect adjustment time so that the medal is paid out after the effect adjustment time has elapsed since the winning flag was generated in step S86.

  In addition, among the plurality of reel stop buttons 7a, 7b, 7c, stop instruction signals 44a to 46a output from the button sensors 44 to 46 corresponding to the last operated button are detected, and the effect adjustment is performed from the detected time. The medal payout start time may be adjusted based on the effect adjustment time so that the medal is paid out after the time has elapsed. In this case, when the determination condition of step S84 shown in FIG. 16 is affirmed, and the process of steps S25 and S26 is executed from the time when the third button stop is detected, and the determination of step S26 is affirmed Then, the process may proceed to step S27 shown in FIG.

  This point is important in the production by the sub reel. In the present embodiment, as described with reference to FIG. 4, the layout of the symbols on the main reels is determined such that different types of symbols are lined up on the first display unit 10A even if a winning combination is achieved. ing. Therefore, the player cannot immediately determine whether or not a winning combination has been achieved even when watching the state in which the variable display of the first display unit 10A is stopped. Therefore, it is conceivable to perform various effects by rotating the sub reel even after the main reel stops. However, when the player wins the role and pays out the medals, the player senses from the situation that the player has won the role, and on the other hand, if there is no payout, the player detects that the player has lost. For this reason, the effect of the sub reels performed after the main reel is stopped becomes meaningless. Therefore, on the basis of the stop of the main reel, the payout of medals is prohibited until the effect adjustment time elapses, while the effect adjustment time information is transmitted to the sub-board 30B, and the stop operation of the reel stop buttons 7a, 7b, 7c is performed. By transmitting the stop button number and the stop symbol number each time, the stop timing of the main reel is notified to the sub-board 30B, and an appropriate effect is produced on the sub-board 30B based on the effect adjustment time and the stop timing of the main reel. They were able to choose.

  Next, the main CPU 31 sequentially determines whether or not a watermelon prize, a bell prize, a cherry prize, or a plum prize has been won based on the winning flag (steps S27 to S30), and refers to the winning symbol combination table TBL3. Each part is controlled so as to pay out a number of medals according to the winning combination (steps S31 to S34).

  Next, the main CPU 31 determines whether or not an RB game is in progress (step S35). In the present embodiment, an RB flag indicating that the RB game is being performed is set in an RB game start process (steps S39 and S42) described later, and the RB flag is cleared in the RB game end determination process (step S36). Has become. Therefore, whether or not the RB game is being performed is determined based on whether the RB flag is set or cleared.

  If the main CPU 31 determines that the game is in the RB game, the process proceeds to step S36, and executes the RB game end determination process. In the RB game end determination processing, it is determined whether the RB game has been performed a predetermined number of times, and if the RB game has been performed a predetermined number of times, the RB flag is cleared.

  On the other hand, when it is not during the RB game, the result of the determination in step S35 is “NO”, and the main CPU 31 determines whether or not a single RB prize has been won (step S37). When a single RB prize has been won, the main CPU 31 pays out a predetermined number of medals (step S38) and executes an RB game start process (step S39). In this process, the RB flag is set. If the single RB prize has not been won, the main CPU 31 determines whether or not the RB has been won during the BB (step S40). If it is an RB prize during the BB prize, the main CPU 31 pays out a predetermined number of medals (step S41) and executes an RB game start process (step S42). In this process, the RB flag is set.

  Next, if the RB prize during BB has not been won, the main CPU 31 determines whether or not the BB game is in progress (step S43). Similarly to the above-described processing relating to the RB game, in the present embodiment, a BB flag indicating that the BB game is being performed is set in a BB game start processing (step S47) described later, and the BB game end determination processing (step S44). , The BB flag is cleared. Therefore, the determination as to whether or not the BB game is in progress is made based on whether the BB flag is set or cleared.

  When the BB game is in progress, the main CPU 31 executes a BB game end determination process (step S44). In this process, it is determined that the BB game has ended when the big bonus game reaches a predetermined number of games (for example, 30 games) or when the last RB in the BB ends.

  If it is not during the BB game, it is determined based on the winning flag whether or not a BB prize has been won (step S45). If the BB prize has been won, the main CPU 31 executes a medal payout process (step S45). (S46), a BB game start process is executed (step S47).

  Thereafter, the main CPU 31 executes a one game end process (step S48). In this process, first, the main CPU 31 determines whether the BB prize or the RB prize has been missed. The missing of the BB prize or the RB prize means that the BB prize or the RB prize cannot be won while the BB prize or the RB prize has been won in the internal lottery process (step S15). When the winning flag is set and the RB winning flag or the BB winning flag is cleared, the main CPU 31 determines that the BB prize or the RB prize has been missed. It is determined that the RB prize has not been missed. If no miss is found, the RB winning flag and the BB winning flag are cleared, and the data value of each bit of the internal lottery data ISD is cleared to "0". As a result, carryover of the winning flag is eliminated. On the other hand, if there is any missing, the main CPU 31 does not clear the RB winning flag and the BB winning flag. Thereafter, the main CPU 31 releases the prohibition of the bet operation (step S49). As a result, the RB winning flag and the BB winning flag are carried over to the next game.

  The processing of the effect adjustment time performed in steps S25 and S26 may be performed as needed in the processing after step S22. For example, immediately before step S36 or immediately before step S41. May be performed.

<1-5: Sub-substrate processing>
Next, the processing of the sub CPU 55 on the sub board 30B will be described. 17 and 18 are flowcharts showing the contents of the entire processing of one game on the sub reel. This process proceeds by the sub CPU 55 repeatedly executing the second control program CP2 at a predetermined cycle independently of the control program CP1 executed by the main CPU 31. The sub CPU 55 changes the display mode of the sub reels into a first process and a second process. The first process is to change the display mode of the sub reels according to the rotation of the main reel, while the second process is not to change the display mode of the sub reels according to the rotation of the main reel. In other words, the first process is to change the display mode of the sub reels so as to correspond to the display mode of the symbol displayed on the first display window 4A by rotating the main reel, while the second process is The display mode of the sub reels is changed so that the display mode is different from the display mode of the symbol displayed on the first display window 4A.

  The display mode of the symbol displayed in the first display window 4A means the behavior of the symbol displayed therein, such as forward rotation in which the symbol moves from top to bottom and reverse rotation in which the symbol moves from bottom to top. The direction of rotation of the main reel, the rotation speed of the main reel, the rotation acceleration of the main reel, whether the main reel is stopped or rotated, and whether the main reel is rotating at a constant speed or frame-by-frame, etc. are applicable. In the first process, for example, if the main reel is rotating forward, the sub reel is also rotating forward, and if the rotation of the main reel is started and accelerated, the same applies to the sub reel. However, it is not necessary for all of the symbol behaviors such as normal rotation / reverse rotation, speed, acceleration, stop / movement, normal / frame feed, to correspond, and at least one of them is sufficient.

  First, the sub CPU 55 determines whether or not the winning acquisition flag is “1” (Step S90). The winning acquisition flag is set to “1” when the internal lottery information is acquired from the main board 30A for each game. Upon receiving the internal lottery information, the sub CPU 55 executes a sub reel variable mode selection process (step S91).

  FIG. 19 shows the processing contents of the sub reel variable mode selection processing. In this process, the sub CPU 110 selects a variable display pattern for the first process based on the internal lottery information (step S110). As described above, the first process changes the display mode of the sub reels in accordance with the rotation of the main reel. There are various patterns in the variable display corresponding to the rotation of the main reel. For example, a control pattern that controls the rotation speed of the sub-reel to approach the rotation speed of the main reel, or a control pattern that controls the rotation phase of the sub-reel in synchronization with the rotation phase of the main reel, and a sub-reel to synchronize the rotation phase The case where the rotation phase of the main reel rotates by one frame or the case that the rotation of the main reel rotates by two frames are included.

  Next, based on the internal lottery information, the sub CPU 55 determines the stop position of the sub reel at the time of winning (Step S112), and also determines the stop position of the sub reel at the time of non-winning (Step S113). That is, the final scheduled stop position of the sub reels is determined for each sub reel separately for winning and non-winning.

  When the internal lottery information indicates that a certain winning combination has been won, the symbols constituting the winning combination are drawn on the winning line of the main reel, and the main reel and sub reels are set so that the winning combinations other than the winning combination do not win. Is controlled. When the internal lottery information indicates a loss, the stop positions of the main reel and the sub reel are controlled so as not to win all the winning combinations. However, even if the player has won the internal lottery, the symbols constituting the winning combination may not be able to be drawn into the winning line information depending on the operation timing of the reel stop button of the player. The stop position of the sub reel at the time of winning in step S112 means the stop position of the sub reel when there is a possibility of winning. That is, in the description of FIG. 19, at the first and second stop stages, it is not known whether or not a final prize will be won. The possibility of winning is included in the concept of winning.

  Returning to FIG. 17, the description will be continued. When the sub reel variable mode selection processing is completed (step S91), the sub CPU 55 advances the processing to step S92, determines whether or not the left main reel start flag is “1”, and sets the flag to “1”. If it is, the start processing of the left sub reel is executed (step S93). The sub CPU 55 also executes a start process for the middle sub reel and the right sub reel in the same manner (steps S94 to S97). Each main reel start flag is set to "1" when the reference point passage signals 47c to 49c output from the left, center, and right reel position detection sensors 47C to 49C provided on the main reel become active. Details of this point will be described later.

  FIG. 20 is a flowchart showing the contents of the start processing of the left sub reel. Note that a similar start process is executed for the middle and right sub reels. The sub CPU 55 selects a variable display pattern for left sub reel processing based on the internal lottery information (step S120), and controls the variable display based on the selected variable display pattern (step S121). The variable display pattern means a variable mode of display contents.

  Returning to FIG. 17, the description will be continued. In step S98, the sub CPU 55 determines whether or not all the sub reels have started, and repeats the processing from step S92 to step S97 until the rotation of all the sub reels starts.

  Thereafter, the sub CPU 55 proceeds to step S99 shown in FIG. 18, determines whether or not the left main reel stop flag is “1” (step S99), and if the flag is “1”. A left sub reel stop process is executed (step S100). The sub CPU 55 also executes a stop process for the middle sub reel and the right sub reel with reference to each main reel stop flag (steps S101 to S104). Each main reel stop flag is generated based on a stop button number transmitted from the main CPU 31. That is, when the stop button number for instructing the pressing of the left reel stop button 7a is input to the sub-board 30B, the sub CPU 55 sets the left main reel stop flag to “1” and sets the input stop button number to the middle reel. When instructing to press the stop button 7b, the middle main reel stop flag is set to “1”. When the input stop button number instructs to press the right reel stop button 7c, the right main reel stop flag is set. Set to “1”. In the present embodiment, the sub-reel rotation control by the sub-reel start processing corresponds to the above-described first processing, whereas the sub-reel rotation control by the sub-reel stop processing corresponds to the above-described second processing. Then, in response to the operation of each reel stop button, switching between the above-described first processing and second processing is executed.

  FIG. 21 is a flowchart showing the contents of the left sub reel stop processing. As shown in this figure, the sub CPU 55 selects a variable display pattern for the second processing based on the input stop information (step S130). Here, the stop information is information indicating a stop position of the left main reel, and corresponds to, for example, the number of drive pulses from a reference point or the above-mentioned stop symbol number. The stop information is generated by the main CPU 31 of the main board 30A and transmitted to the sub board 30B. Here, a plurality of variable display patterns are prepared as the variable display patterns for the second processing, including not performing the second processing.

  Next, the sub CPU 55 determines whether to execute the second process based on the variable display pattern selected in step S130 (step S131). When performing the second process, the variable display is started with the variable display pattern for the second process (step S132). Then, based on the stop information, it is determined whether there is a prize or a possibility (step S133). At this time, the internal lottery information is referred to. That is, when the winning combination with the internal lottery information is instructed, it is determined whether or not the symbol constituting the combination on the main reel can be drawn on the winning line. The determination as to whether or not there is a prize is performed when the operation of the left reel stop button 7a is the last stop operation, and the determination as to the possibility of winning is made from the beginning to immediately before the last, that is, the first and the last. Executed in the second stop operation.

  If there is a win or a possibility of winning, the sub CPU 55 controls the left reel drive motor 51B so that the sub reel is stopped at the stop position of the sub reel at the time of winning (step S134). On the other hand, if there is no winning or the possibility of winning, the sub CPU 55 controls the left reel drive motor 51B so that the sub reel is stopped at the stop position of the sub reel at the time of non-winning (step S134).

  For example, when a symbol constituting the BB combination is stopped on the winning line as a result of winning the BB combination by the internal lottery and performing the first stop operation by the player (that is, when there is a possibility that the BB may win). Executes stop control according to the stop mode selected when there is a possibility of winning. That is, until the stop operation is received, the synchronous control with the rotation of the main reel is performed, and after the stop operation, the stop position of the sub reel is adjusted according to the determined stop mode.

  FIG. 22 shows an example of the second processing. FIG. 7A shows an example of reverse rotation. In the variable display pattern, the rotation speed of the sub reel becomes negative after the first processing is completed. That is, the sub reel rotates in the reverse direction. For example, this corresponds to a case where the sub reel is stopped after passing by one frame, the sub reel is rotated reversely by one frame, and the symbols constituting the winning combination are stopped on the winning line. FIG. 8B shows an example of frame advance. In this variable display pattern, after the first processing is completed, the sub reel is rotated three times in the forward direction. In this example, three sub-frame feeds are realized by controlling the sub-reel so as to advance one frame by one rotation.

  If the determination condition is negative in step S131, that is, if the second process is not executed, the sub CPU 55 advances the process to step S136 and continues the variable display in the variable display pattern for the first process. (Step S136). Then, based on the stop information, it is determined whether there is a prize or a possibility (step S133). The determination as to whether or not a winning is made when the operation of the left reel stop button 7a is the last stop operation. The possibility of winning is determined from the beginning to immediately before the last, that is, the first and the second. It is executed in the stop operation of. In this case, the rotation of the main reel and the rotation of the sub reel are as shown in FIG.

  If there is a win or a possibility of winning, the sub CPU 55 controls the left reel drive motor 51B so that the sub reel is stopped at the stop position of the sub reel at the time of winning (step S134). On the other hand, if there is no winning or the possibility of winning, the sub CPU 55 controls the left reel drive motor 51B so that the sub reel is stopped at the stop position of the sub reel at the time of non-winning (step S134). In this case, the rotation of the main reel and the rotation of the sub reel are as shown in FIG.

  In this embodiment, the stop mode of the sub reels includes three time lengths of 0 sec (for example, FIG. 22C), 3 sec (for example, FIG. 22A), and 6 sec (for example, FIG. 22B). There are a plurality of variable stop modes. Here, the effect time means the length of the effect of the variable stop mode performed when the control is changed from the synchronous control to the asynchronous control, that is, the time of the second processing.

  The main CPU 31 transmits the internal lottery information and the effect adjustment time selected in the lottery to the sub CPU 55. The effect adjustment time is used to select at least a stop mode at the time of stopping the last stopped sub reel (step S130 described above). For example, when the internal lottery information indicates the winning of BB and the effect adjustment time is 6 sec, the variable stop mode of 6 sec for BB is selected. In the case where the symbols related to the winning of the BB are aligned by the stop operation from the beginning to the last immediately before, on the sub reels, for example, the frame feed stop mode shown in FIG. 22B is selected as the third stop mode. Control is executed such that the sub reels stop after 6 seconds from the shift to the second process. On the other hand, the main CPU 31 pays out the medals of the number corresponding to the BB prize to the credits or the medal tray after 6 seconds have elapsed after the main reel has completely stopped, and shifts to the BB game.

  Here, when it is determined that the arrangement of the symbols related to the winning of the BB is not aligned at the time of the stop operation, the stop information of the main reel is obtained by the communication means also in the control of the sub reel, so that the loss effect for the BB is performed. Select At this time, in the sub reel, it is possible to derive an effect of a variable stop mode of 6 sec like a reach action that informs that the BB has won. If it is determined during the stop operation that the arrangement of the symbols related to the winning of the BB is not aligned, the main CPU 31 transmits information of 0 sec as the effect adjustment time by the communication means, and the sub CPU 55 It is also possible to stop in a stop mode of 0 sec for the effect of dropping out. That is, when it is determined that there is no possibility of winning according to each stop operation timing from the beginning to immediately before the last stop operation, the main CPU 31 detects this, changes the effect adjustment time, and changes the changed effect adjustment. The time (for example, 0 sec) may be transmitted to the sub CPU 55. In this case, the main CPU 31 may omit the time delay processing and shift to the next game.

  As described above, the effect adjustment time information is transmitted to the sub CPU 55 in accordance with the result of the internal lottery, and even after the operation is stopped, information different from the previously transmitted effect adjustment time is transmitted again. It may be. Further, the effect adjustment time may be determined after the last stop operation and transmitted to the sub CPU 55.

  Here, what is important is to delay the payout control after the sub reels are completely stopped, and it is not always necessary to make the time of the second processing of the sub reels equal to the delay time. Preferably, the payout control is slightly delayed. Better.

  Returning to FIG. 18, the description will be continued. The sub CPU 55 determines whether all the sub reels have stopped (step S105), and repeats the processing from step S99 to step S105 until all the sub reels stop. Then, when all the sub reels stop, various flags are cleared (step S106). The above is an outline of the processing from the start of rotation of the sub reel to the final stop.

  Next, the processing executed by the sub CPU 55 will be described in more detail. 23 to 25 are flowcharts showing the processing contents of the timer interrupt processing executed by the sub CPU 55. The timer interrupt processing is executed at a predetermined cycle, for example, at a cycle of 2 msec. First, the sub CPU 55 determines whether or not a command has been input from the main board 30A (step S140). If a command has been input, the sub CPU 55 advances the process to step S141 to determine whether or not the command is internal lottery information. When the condition of step S141 is affirmed, the sub CPU 55 acquires the internal lottery information (step S142), and sets the winning acquisition flag to “1”.

  Next, the sub CPU 55 determines whether the command is left / middle / right stop information (steps S144, 147, and 150). The main CPU 31 generates left stop information in response to pressing of the left reel stop button 7a and outputs it to the sub-board 30B, and outputs middle stop information in response to pressing of the middle / right reel stop buttons 7b and 7c. And right stop information is generated and output to the sub-board 30B.

  If the command is the left stop information, the sub CPU 55 acquires the left stop information (step S145), and sets the left main reel stop flag to "1" (step S146). Next, when the command is the middle stop information, the sub CPU 55 acquires the middle stop information (step S147), and sets the middle main reel stop flag to “1” (step S149). Further, when the command is the right stop information, the sub CPU 55 acquires the right stop information (step S151), and sets the right main reel stop flag to “1” (step S152).

  Thereafter, the sub CPU 55 determines whether or not the reference passage signal 47c of the sub reel position detection sensor 47C has been detected (step S153), and if this is detected, whether the left reel start flag is “1”. It is determined whether or not it is not “1”. If it is not “1”, the variable display of the left sub reel is started, that is, the rotation is started (step S155), and the left main reel start flag is set to “1” (step S156). ). On the other hand, if the left main reel start flag is “1”, the sub CPU 55 advances the process to step S157 to execute the left sub reel phase / speed adjustment process. When the rotation of the left main reel is detected (step S153), the left main reel start flag is set (step S156). When the left main reel start flag is "1", the left sub reel phase / speed adjustment processing is executed. Therefore, the left sub reel phase / speed adjustment processing corresponds to the above-described first processing. Note that, similarly to steps S153 to S157, the processing for the middle sub reel is executed in steps S158 to S162, and the processing for the right sub reel is executed in steps S163 to S167.

  In steps S168 to S170, when the sub CPU 55 detects the reference point passing signals 47b to 49b output from the left / middle / right sub reel position detection sensors 47B to 49B, the sub CPU 55 resets the phase shift counters of the left / middle / right sub reels. Clear (steps S171 to S173). Each phase shift counter is configured by, for example, an internal register of the sub CPU 55 or the RAM 59 or the like. The count value of each phase shift counter is used for sub reel phase / speed adjustment processing.

  Next, the sub CPU 55 determines whether or not the left main reel start flag is “1” (step S174). If the determination condition is affirmative, the count value of the left sub reel speed counter is set to “1”. The value is incremented (step S175), and the count value of the phase shift counter of the left sub reel is incremented by "1" (step S176).

  The same process is executed for the middle main reel and the middle sub reel (steps S177 to S179), and the same process is executed for the right main reel and the right sub reel (steps S177 to S179). Each sub reel speed counter is constituted by, for example, an internal register of the sub CPU 55 or the RAM 59. The count value of each sub reel speed counter is used for sub reel phase / speed adjustment processing.

  Next, the phase and speed adjustment processing of the left sub reel will be described in detail. In this process, the rotation of the left sub reel is controlled using the count values of the left reel speed counter and the left sub reel phase shift counter. FIG. 26 is a flowchart showing the processing contents of the phase / speed adjustment processing for the left sub reel. The sub CPU 55 stores the left reel speed counter value in a predetermined memory (for example, the RAM 59) (Step S200). As shown in FIG. 23, the phase / speed adjustment processing is executed when the reference point passage signal 47c becomes active. That is, the phase / speed adjustment processing is executed once per rotation of the left main reel. Then, as described in step S175, the count value of the left reel speed counter is set at the interrupt cycle (2 msec) when the left main reel start flag is “1”, that is, during the period when the left main reel is rotating. The count value is incremented by “1”. Therefore, the count value of the left reel speed counter per rotation corresponds to speed information indicating the rotation speed of the left main reel. It should be noted that the left reel count value for the past 10 rotations is stored in a predetermined memory.

  Next, the sub CPU 55 clears the left reel speed counter to measure the speed of the next rotation (Step S201). Thereafter, the sub CPU 55 accesses the memory and calculates the average value of the speed counter values for the past 10 rotations (Step S202). The average value of the speed information thus obtained is used for the rotation control of the left sub reel.

  Since the timer interrupt and the rotation operation of the main reel operate asynchronously, a counting error occurs even if the main reel is rotating at a truly constant speed. Further, since the main reel has a mechanical structure, an error occurs in the rotation operation to some extent. Further, since the pulse signal of the drive motor is generated by software, it originally includes an error. Therefore, as described above, the number of measurement pulses for 10 rotations is always held, and the average value thereof is obtained, and the rotation speed of the sub reel is controlled with the average value as a target. Therefore, controlling the speed of the main reel and the speed of the sub reel to the same speed means controlling the speed substantially the same, detecting the rotation speed of the main reel and bringing the rotation speed of the sub reel closer to this.

  Next, the sub CPU 55 calculates a half value (1/2) of the average value of the speed counter value (Step S203), and further calculates a difference by subtracting the half value from the left reel phase shift counter value (Step S203). S204). The phase shift counter of the left sub reel is cleared (step S205).

  The count value of the phase shift counter of the left sub-reel is started when the left main reel passes the reference point (the mounting position of the photosensor) and the reference point passing signal 47c is activated, and the left subreel is at the reference point The time until the reference point passing signal 47b becomes active after passing through the attachment position) is shown. That is, the left reel phase shift counter value is phase difference information indicating the phase difference between the left main reel and the left sub reel. In this example, the reference point of the reel position detection sensor 47A for the main board 30A provided on the left main reel and the reference point of the reel position detection sensor 47B for the sub-board 30B are set to positions different by 180 degrees. . The left sub reel rotates so that the timing at which the reel passes the reference point of the reel position detection sensor 47C and the timing at which the left main reel passes the reference point of the reel position detection sensor 47A coincide. The phase is adjusted. That is, when the reference of the rotation of the left main reel is the reference point of the reel position detection sensor 47C, the target is to rotate the left sub reel 180 degrees (predetermined value) with respect to the left main reel. That is, the left sub reel is controlled such that the phase difference between the rotation phase of the left main reel and the rotation phase of the left sub reel approaches a predetermined value (180 degrees in this example).

  Next, the sub CPU 55 determines whether or not the difference value is within a predetermined allowable value range (Step S206). If the difference value is outside the allowable value range, the sub CPU 55 determines whether the difference value is positive. If it is positive, the average value of the speed counter is corrected to be positive to generate a control count value. On the other hand, the average value of the speed counter is corrected to a negative value to generate a control count value.

  Thereafter, the sub CPU 55 calculates the speed from the count value (step S210), and controls to set the speed of the left sub reel. That is, in this example, the rotation speed of the left sub reel is adjusted by feedforward control with the rotation speed of the left main reel as a target, and the rotation phase is adjusted by feedback control.

  According to the phase / speed adjustment processing, the acceleration control is performed when the detection of the sub reel is delayed with respect to the detection of the main reel, and the deceleration operation is performed when the detection of the sub reel is advanced. If the rotation speed of the main reel obtained by the averaging process is delayed by the determination of the phase advance / delay, a predetermined speed value is added to the obtained rotation speed of the main reel, The rotation speed of the sub reel is used. Here, the degree of phase delay may be determined stepwise, and the plus value may be set to +1, +2, +3 according to the step. When it is determined that the phase is advanced, a predetermined speed value is subtracted from the rotation speed value of the main reel. For example, when one rotation is performed at 75 msec and the phase is delayed, the speed of 75 msec is originally set to 75.2 msec, which is 0.2 msec faster than the main reel 75 mesc. When the phase shift amount is large, for example, control is performed so as to be +1 msec, such as 76 msec.

  As described above, according to the first embodiment, when the main reel starts rotating by operating the start lever 6, the sub CPU 55 detects the rotation of the main reel by the reel position detection sensors 47C to 49C, The first process is started so that the sub reel rotates according to the rotation of the main reel, and the variable display on the sub reel is switched from the first process to the second process when the operation timing of the reel stop button is triggered. In the first process, the speed and phase of both reels are synchronized. Further, the symbols on the sub reels are arranged such that the symbols constituting the combination are the same type of symbols. Therefore, the player stops the predetermined symbol on the winning line of the main reel by operating the reel stop buttons 7a, 7b, 7c at a timing when the symbol constituting the combination is within the predetermined pull-in range while watching the sub reel. It is possible to win a prize. In this case, since the stop symbols of each main reel are seemingly unrelated, the player cannot easily know whether or not a prize has been won simply by looking at the main reel. Will do. Then, in the sub reel, the second processing such as reverse rotation and frame advance is executed in the display pattern for effect irrespective of the rotation of the main reel, so that various effects by the reel can be executed.

<1-6: Modification of First Embodiment>
In the first embodiment described above, the following modifications are possible.

  (1) In the first embodiment, in order to detect the rotation of the main reel, the reel position detection sensors 47A to 49A used for controlling the rotation of the main reel itself and the rotation of the sub reel are controlled. Although the used reel position detection sensors 47C to 49C are provided, they may be used in combination.

  (2) In the above-described first processing, the speed and the phase of the sub reel are controlled so as to approach the rotation of the main reel, but any one of them may be controlled.

  (3) In the second process described above, an effect process such as blinking the left, middle, and right backlights 65, 66, and 67 while the left, middle, and right reels Rb1, Rb2, and Rb3 are rotating may be added. Good.

<2. Second Embodiment>
Next, a slot machine according to a second embodiment of the present invention will be described. In the slot machine of the first embodiment described above, the sub CPU 55 directly detects the reference point passage signals 47c to 49c generated by the reel position detection sensors 47C to 49C. On the other hand, in the second embodiment, the main CPU 31 (first control unit) detects that the reference point passage signals 47c to 49c have become active, generates a detection command, and outputs the detection command via the data transmission circuit 37. The signal is transmitted to the sub board 30B. In this case, the sub CPU 55 of the sub board 30B checks whether or not the detection command is input from the main board 30A at the timer interrupt interval (2 msec), and determines the input timing of the detection command by the reference point passing signals 47c to 49c. Treat as active timing. Alternatively, an interrupt process may be executed upon input of a detection command.

  Here, since the commands include various commands in addition to the detection commands, it is necessary for the sub CPU 55 to measure the interval of occurrence of only the detection commands and to provide speed information based on the measurement result. The main board 30A and the sub-board 30B are connected by a predetermined line, and by activating the predetermined line, the fact that the reference point passing signals 47c to 49c have become active is transmitted from the main board 30A to the sub-board 30B. It may be transmitted. In this case, since the transmission is performed by the dedicated line, the step of determining the type of the command can be omitted.

  The main board 30A and the sub-board 30B operate asynchronously using different clock signals, and information such as a command transmitted from the main board 30A is transmitted with a random delay from the viewpoint of fraud prevention. May be done. Even in such a case, by performing the above-described averaging process, it is possible to remove noise due to transmission, specifically, an error due to a random delay time.

  Also in the present embodiment, similarly to the first embodiment, the reel position detection sensors 47A to 49A used for controlling the rotation of the main reel itself and the reel position detection sensor 47C used for controlling the rotation of the sub reel. To 49C.

<3. Third embodiment>
In the above-described first and second embodiments, a slot machine employing a mechanical sub-reel has been described as an example of the second display unit 10B. However, the slot machine according to the third embodiment is not limited to the second display unit 10B. An image display device is used.

  FIG. 27 shows an external configuration of a slot machine according to the third embodiment. The slot machine 1 is provided with an image display device 91 at the center. 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. In the present embodiment, three display columns imitating the sub reels described above are displayed on the image display device 91 as video reels. On each video reel of this example, 21 pieces and seven types of symbols are displayed in the same manner as the sub reel shown in FIG.

  Next, an electrical configuration of the slot machine 1 according to the third embodiment will be described. This slot machine 1 is configured similarly to the slot machine 1 of the first embodiment described with reference to FIGS. 7 and 11 except for the detailed configuration of the sub-board 30B. FIG. 28 shows a block diagram of a sub-board 30B and its peripheral circuits according to the third embodiment.

  In the third embodiment, since the image display device 91 is used instead of the sub reel, the reel position detection sensors 47B to 49C used in the first embodiment are not provided. The ROM 58 stores symbol image data DG indicating images of symbols arranged on the sub reels. The symbol image data DG is managed separately for each type of symbol, and is read from the ROM 59 as needed. In this example, seven symbol image data DG1 to DG7 such as “7”, “plum”, “bell”, “cherry”, “replay”, and “BAR” are stored in the ROM 58. Further, in the ROM 58, address information indicating a storage area of each of the symbol image data DG1 to DG7 and a symbol code for identifying each symbol image data are stored in association with each other. The sub CPU 55 generates a sequence of the symbol codes according to the control program CP2, controls the display order of the symbols, acquires the address information corresponding to the symbol codes, reads out each symbol image data DG1 to DG7 from the ROM 58, Transfer to VRAM 90. The ROM 58 functions as an image storage unit that stores the symbol image data DG.

  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 image data DG read from the ROM 58 during the vertical blanking period into the VRAM 90, and reads and supplies the display image data from the VRAM 90 during 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 content of the VRAM 90.

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

  As described above, the sub CPU 55 updates the display image data by writing the symbol image data DG into the VRAM 90, but the first processing for controlling the second display unit 10B so that the display mode is in accordance with the rotation of the main reel. As in the first embodiment, the second process for controlling the display mode regardless of the rotation of the main reel is performed.

  That is, the sub CPU 55 detects the rotation speed of each main reel based on the reference point passage signals 47c to 49c. Specifically, as described with reference to FIG. 26 in the first embodiment, the rotation of the main reel is performed based on the number of timer interrupts generated between a certain reference point passing signal and the next reference point passing signal. Detect speed. In this case, the average value of the past rotation speeds is calculated, and the average value is used as the rotation speed value of the main reel, as in the first embodiment. Then, the sub CPU 55 updates the storage content of the VRAM 90 so that the moving speed of the display image matches the detected rotation speed. Further, since the reference point passing signals 47c to 49c are phase information indicating the rotation phase of the main reel, the sub CPU 55 determines that the image of the corresponding symbol is predetermined at the timing when each of the reference point passing signals 47c to 49c becomes active. The writing to the VRAM 90 is controlled so as to be displayed at the position. Thereby, the first process is executed.

  Matching the phases of the main reel and the video reel means matching the symbol position corresponding to the reference position of the main reel with the symbol position of the symbol image data DG. In the case of a video reel, there is no mechanical restriction, so it is arbitrary which position is used as the reference point, but from the viewpoint of facilitation of control, it is preferable to set the head of the symbol image data DG as the reference position. .

  In the phase matching process, when the sub CPU 55 detects the reference position of the main reel, the display position of the video reel may be forcibly returned to the head. However, if the phases are not synchronized, the player will immediately see the symbol image jumping. For this reason, the image on the video reel may be returned to the beginning step by step, or may be controlled so as to be gradually adjusted during the next round.

  On the other hand, the second process is the same as that described in the first embodiment with reference to FIGS. 17 to 21 except that the control target is the image display device 91 instead of the sub reel. That is, the writing to the VRAM 90 is controlled based on the stop positions of the sub reels at the time of winning and at the time of non-winning (in this example, stopped symbols).

  In the third embodiment, similarly to the second embodiment, the main CPU 31 (first control unit) detects that the reference point passage signals 47c to 49c have become active, generates a detection command, and transmits data. The signal is transmitted to the sub-board 30B via the circuit 37. In this case, the sub CPU 55 of the sub board 30B checks whether or not the detection command is input from the main board 30A at the timer interrupt interval (2 msec), and determines the input timing of the detection command by the reference point passing signals 47c to 49c. Treat as active timing. Alternatively, an interrupt process may be executed upon input of a detection command. Further, the detection command may be transmitted through a dedicated line. In addition, the reel position detection sensors 47A to 49A used to control the rotation of the main reel itself and the reel position detection sensors 47C to 49C used to control the rotation of the sub reels may be used.

<6: Modification>
Although the present invention has been described in connection with the presently most practical and preferred embodiments, the invention is not limited to the embodiments disclosed herein. Rather, the invention can be modified as appropriate without departing from the spirit or spirit of the invention which can be read from the claims and the entire specification, and a gaming machine with such a change and a control method thereof are also included in the technical scope of the present invention. Must be understood as being done. For example, the modifications described below are, of course, included in the present invention.

  (1) In each of the above-described embodiments, when the player operates the start lever 6, the main CPU 31 detects a detection signal from the start lever sensor 43 and transmits the detection signal to the sub CPU 55 as start information. When the reel stop buttons 7a to 7b are operated, the detection signals 44a to 46a from the left / middle / right reel stop button sensors 44 to 46 are detected and transmitted to the sub CPU 55 as stop operation information. Here, the sub CPU 55 executes the first processing or the second processing according to a predetermined rule during a period from the input of the start information to the input of the stop operation information, and performs the second processing after the input of the stop operation information. May be executed. Alternatively, the sub CPU 55 executes the first processing or the second processing in accordance with a predetermined rule during a period from when the rotation of the main reel (the rotation of the first display means) is detected to when the stop operation information is input, The second process may be executed after inputting the stop operation information.

  For example, during rotation, that is, during the period from when start information is input to when stop operation information is input, the rotation control of the sub reel is changed from synchronous control (first processing) to asynchronous control (second processing), for example, temporarily. Alternatively, the rotation may be switched to the high-speed rotation by a predetermined rotation and then returned to the synchronous rotation again. As described above, instead of shifting from the first process to the second process and finally stopping, during the period from when the start information is input to when the stop operation information is input, the temporary stop during the synchronization control is performed. After the asynchronous control, the control may be returned to the synchronous control.

  (2) In each of the above-described embodiments, when the main reel and the sub reel (including the video reel) have the same phase, control may be performed so that subsequent phase adjustment is not performed. The same is true for In this case, the sub-reel may be controlled to rotate at a constant speed.

  (3) In each of the embodiments described above, in the first process, the rotation of the sub reels or the display of the video reels is synchronized with the rotation of the main reel. However, the two are not completely synchronized but have a displacement of several frames. It may be one that rotates in conjunction with it. In this case, even if the player operates the reel stop buttons 7a, 7b, 7c at the timing when the desired symbol is stopped at the desired position, the stop symbol is shifted. For example, as shown in FIG. If the pull-in range is set to 4 frames and the stop button is operated at the timing of the symbol numbers PN = 12 to 21 in the stop operation of the middle reel Rb2 and the right reel Rb3, "7" can be pulled in. .

  (4) In the above-described embodiment, the plurality of types of symbols displayed on the main reels Ra1 to Ra3 are constituted by sets of figures having different numbers. However, the symbols of the main reels Ra1 to Ra3 and the sub reels Rb1 to Rb3 are formed. The correspondence may be as shown in FIGS. 29 and 30. In the example shown in FIG. 29, a plurality of types of symbols displayed on the main reels Ra1 to Ra3 are configured by sets of figures having the same shape and different colors. In the example shown in FIG. 30, the symbols are displayed on the main reels Ra1 to Ra3. Are composed of a set of figures having different corner shapes. According to these examples, it is possible to make it difficult for the player to recognize whether or not a prize has been won even at a glance at the main reels Ra1 to Ra3, and to attract the player's interest to the sub reels Rb1 to Rb3.

  Further, the plurality of types of symbols displayed on the main reels Ra1 to Ra3 may be constituted by a set of figures having the same color but different shapes, that is, those having the same color but different shapes. In this case, since the printing plate production cost and the printing process can be reduced, the cost can be reduced. In addition, the plurality of types of symbols displayed on the main reels Ra1 to Ra3 may be a set of graphics obtained by rotating a graphic having a predetermined shape by different angles. For example, “△” obtained by rotating the figure of “△” by 0 degrees and “▽” obtained by rotating the figure by 180 degrees may be included.

  (5) In the embodiment described above, the plurality of types of symbols displayed on each of the plurality of main reels Ra1 to Ra3 correspond one-to-one with the plurality of types of symbols displayed on each of the plurality of sub reels Rb1 to Rb3. However, the present invention is not limited to this. For example, some or all of the symbols on the sub reels Rb1 to Rb3 may correspond to a plurality of types of symbols on the main reels Ra1 to Ra3. Conversely, some or all of the symbols on the main reels Ra1 to Ra3 may correspond to a plurality of types of symbols on the sub reels Rb1 to Rb3.

  Also, the number of sub reels does not necessarily have to match the number of main reels, and may be greater or less than the number of main reels. Further, for example, the number of rows of the sub reels may not be the same as that of the main reel, and may be, for example, only one row. Further, the number of pay lines on the sub reels may not be the same as that on the main reel, and for example, may have eight pay lines. Furthermore, when the image display device 91 is used as the second display unit 10B, it is not always necessary to display a display row on the image display device 91, and for example, a roulette game may be displayed. In this case, a game completely different from that of the main reel can be displayed, so that the degree of freedom of the game in the slot machine can be increased, and the taste can be greatly improved. Also, an animation in which a plurality of symbols move vertically and horizontally or diagonally, an animation in which a plurality of symbols arranged in an annular shape rotates, or an animation in which symbols are displayed one by one may be used. In short, if the variable speed of an image such as an animation in the first process is in accordance with the rotation of the main reel, and if the image is displayed regardless of the rotation of the main reel in the second process, Such an image may be used. Further, when the sub reel is a video reel, it is possible to perform various effects by animation after stopping the variable display of the video reel. Therefore, the payout control may be performed after the animation has started.

  (6) In the above-described embodiment, after an effect based on the effect adjustment time is first started, stop operation information such as a stop symbol and a stop button number may be obtained to change the effect mode. For example, when the BB prize is won by the internal lottery but does not win, when the last reel stop button is operated, it is determined that the prize has not been won. In this case, after stopping the sub-reel in a manner that does not win, the sub-reel is controlled to perform re-rotation, and the sub-reel is stopped in a manner to win the BB prize, thereby internally winning the BB prize. The player may be notified. Since the player plays while watching only the sub reels, it is better to notify the player with the reach eye than in the mode of winning the BB prize. Alternatively, the production may be stopped when no prize is won, and the production may be performed only when a prize is won.

(7) Next, several examples of the first processing and the second processing of the sub reel will be described. FIGS. 31 and 32 show the behavior of the sub reel according to the modification. In these figures, the horizontal axis represents time, and the vertical axis represents the rotation speed of the sub reel. A solid line indicates a period, and a dotted line indicates a change in speed of the sub reel. Further, in this example, it is assumed that the main reel is rotating normally, and the first processing and the second processing are distinguished by the rotation direction of the sub reel. Therefore, in the first process, the sub reel is rotated forward (rotation in the same direction as the main reel), and in the second process, the sub reel is rotated reversely (rotation in the direction opposite to the main reel).

  In the example of FIG. 31A, the sub CPU 55 executes the first process or the second process in a period T1 from when the start information A is input to the sub CPU 55 to when the stop operation information B is input. The start information A is information indicating directly or indirectly the start of rotation of the main reel, and may be a start flag obtained by detecting the rotation of the main reel, or a start lever sensor 43. Or a command obtained by detecting the detection signal by the main CPU 31. The stop operation information B is obtained by detecting the stop instruction signals 44a, 45a, 46a from the left / middle / right reel stop button sensors 44 to 46 or the main CPU 31 detecting the stop instruction signals 44a, 45a, 46a. It may be a stop button number.

  For example, when the sub reel is rotated forward as indicated by the dotted line, the processing in the period T1 is the first processing. Whether to select the first processing or the second processing is determined by the sub CPU 55 according to the control program. For example, the second process may be executed when a predetermined winning flag included in the internal lottery data ISD transmitted from the main CPU 31 is set. More specifically, a winning flag, a BB winning flag, or an RB winning flag corresponding to a predetermined small win corresponds.

  When the player operates the stop buttons 7a to 7c, the main CPU 31 starts stop control so as to stop the rotation of the corresponding main reel, and transmits the stop button number to the sub CPU 55. The sub CPU 55 detects this, and starts control to reverse the sub reel.

  In the period T2, the rotation of the main reel is stopped, and the sub reel is rotating in the reverse direction. Therefore, in the period T2, the sub CPU 55 executes the second processing. In this example, the rotation of the sub-reel is continuously shifted from the normal rotation to the reverse rotation. However, the rotation of the sub-reel may be temporarily stopped, and then the rotation may be reversed.

  Next, in FIG. 31B, in the period T1, the sub CPU 55 selects and executes the first process or the second process, and controls the sub reels to stop the variable display when the stop operation information B is input. An example is shown below. When the start information A is supplied, the sub CPU 55 selects and executes the first process or the second process, and controls the reel drive motor so as to stop the sub reel upon input of the stop operation information B. For example, when the sub reel rotates in the reverse direction as indicated by the dotted line in FIG. 31B, the sub CPU 55 selects the second process.

  Next, in FIG. 31C, during the period from when the start information A is input to the sub CPU 55 until a predetermined time elapses, one of the first processing and the second processing selected according to the predetermined rule is continued. An example is shown in which, after a lapse of a predetermined time, the other of the first processing and the second processing is executed. Here, it is assumed that the time before and after the elapse of the predetermined time is divided into a period T3 and a period T4. The sub CPU 55 selects the second process in the period T4 when selecting the first process in the period T3, and selects the first process in the period T4 when selecting the second process in the period T3.

  More specifically, the sub CPU 55 has a timer function for measuring time by counting an interrupt signal of a predetermined period, and when detecting that the start information A has been input, starts measurement using the timer function. It is determined whether or not the measured value has reached a predetermined time. After determining that the predetermined time has been reached, sub CPU 55 executes the other process. If the stop operation information B is input before the predetermined time has elapsed, the process may be shifted from one process to the other process.

  For example, as shown by the dotted line in FIG. 31C, the sub CPU 55 selects the first process when the sub reel rotates in the period T3, and the sub CPU 55 selects the first process when the sub reel rotates in the period T4. 2 Select processing.

  Next, in FIG. 32A, a period T5 from when the start information A is input to the sub CPU 55 to when the stop operation information B accompanying the first stop operation is input is a predetermined rule for each sub reel. The first processing or the second processing selected according to the above is continuously executed, and when the stop operation information B associated with the first stop operation is input, the sub reel corresponding to the stop operation information is stopped. And an example of executing the other process not selected in the period T5 on at least one of the other rotating sub reels. The time after the period T5 is referred to as a period T6, and it is assumed that the player first operates the left reel stop button 7a.

  In this case, upon detecting the start information A, the sub CPU 55 selects and executes the first process or the second process for each sub reel. In the example shown in FIG. 32A, the sub CPU 55 selects the first process for all the sub reels and controls the left, middle, and right sub reels to rotate forward. Thereafter, when the player operates the left reel stop button 7a, the stop button number is supplied from the main CPU 31 to the sub CPU 55 as stop operation information B. Upon detecting the stop operation information B, the sub CPU 55 controls to stop the rotation of the left sub reel, and reverses the rotation direction of the middle and right sub reels. In this state, the center / right main reel is rotating. Therefore, the sub CPU 55 executes the second process which is not selected in the period T5 for the middle / right sub reel in the period T6.

  In this example, the processing state of the other sub reels is changed in response to the input of the stop operation information B of a certain main reel, so that the processing between a plurality of sub reels can be associated with each other, thereby greatly improving the attractiveness of the effect. be able to.

  Next, in FIG. 32B, after the start information A is input to the sub CPU 55, one of the first processing and the second processing is selected and executed for at least one sub reel, and the other processing is performed. An example in which the other process different from at least one sub reel is executed for the sub reel is described.

  In this example, when the start information A is input, the sub CPU 55 executes the first process on the left sub reel to control the left sub reel to rotate forward, while controlling the middle and right sub reels to perform the first process. Two processes are executed to control the middle and right sub reels to reverse. Thus, when the player operates the start lever 6, the behavior of at least one of the sub reels can be made different from the behavior of the other sub reels. As a result, the taste of the effect by the sub reel is greatly improved. Note that, of course, the above-described selection of the first processing and the second processing may be appropriately combined. In this modification, a mechanical sub reel is described as the second display unit 10B. However, as in the third embodiment, an image display device is used instead of the sub reel, and the sub reel is imitated there. A display column may be displayed.
