Description

  The present invention relates to a gaming machine represented by a slot machine (pachislot) and a pachinko machine.

  Conventionally, for example, a slot machine has been known as one of the gaming tables. This slot machine rotates the reels by inserting medals and operating the start lever, determines the role internally by internal lottery, and stops the reels by operating the stop button, on the symbol display window When a predetermined combination of symbols is displayed according to an internal decision, a combination is established. When a combination with payout of medals is established, a prescribed number of medals corresponding to the established combination are paid out.

  When a stop button is operated, a predetermined reel is provided in such a gaming table within two symbols from the symbol at the moment the stop button is operated (the symbol at the moment the stop button is operated and the next symbol). There is a slot machine that mounts an MB (middle bonus) game to be stopped (for example, Patent Document 1).

  In recent years, in order to improve the visibility of symbols, the size of one symbol has been increased as much as possible by enlarging the reel, but the space is limited. Therefore, it has been proposed to reduce the number of symbols applied to one reel from 21 to 20 to increase the size of one symbol.

  However, according to the rules, there is an upper limit on the rotation speed of the reels (80 rotations per minute or less), and in the MB game, one or more predetermined reels must stop within 75 msec. Therefore, when the number of symbols applied to one reel is 20, in the MB game, in consideration of the safety and reliability of the game, a stop within a range of 0 frames from the symbol at the moment when the stop button is operated (so-called stop). However, there is a problem that the stop mode becomes monotonous.

  Here, the above situation will be described in detail using specific numerical values. There is a rule that the maximum rotation speed of the reel is 80 rotations per minute, and this rotation speed must not be exceeded. Considering the case where the reel is rotated at this maximum speed, the time required for one rotation of the reel is 750 msec (= 60000 ms / 80 rotations). Therefore, when the number of symbols applied to one reel is 21, one symbol is required. Is 35.7 ms (= 750 ms / 21). As described above, in the MB game, the reels must be stopped within 75 msec from the stop operation. Therefore, when the number of symbols applied to one reel is 21, two symbols (the symbol at the moment of the operation and the next symbol) are used. Can be moved. That is, when the number of symbols applied to one reel is 21, one frame can be controlled to be pulled in the MB game.

  On the other hand, when the number of symbols applied to one reel is set to 20, the time required for moving one symbol is 37.5 ms (= 750 ms / 20), and the last two symbols can be moved numerically. It is. However, since the actual reel rotation speed is set to less than 80 rotations (for example, 79 rotations) in consideration of the accuracy error of each product, the movement of one symbol is practically the limit. That is, when the number of symbols applied to one reel is 20, only the pull-in control of 0 frames in the MB game, that is, the so-called bitter stop can be performed.

  In the case where the number of symbols applied to one reel is 20 as described above, only the so-called "bitter stop" can be performed in the MB game, and the stop mode is monotonous.

  The present invention has been made in view of the above circumstances, and provides a gaming table capable of realizing various stop modes even in a state where the reels must be stopped within a shorter stop range than usual. The purpose is to provide.

In order to achieve the above object, the gaming machine according to the present invention has, as one mode, a reel on which a plurality of types of symbols are provided, a rotor to which the reel is connected, and a plurality of pulses to which a pulse-like exciting current is supplied.

FIG. 8 is an exploded perspective view of the stepping motor 700. As shown in FIG. 8, the stepping motor 700 includes a motor shaft 710, a case member 720 supporting the motor shaft 710, a first bearing 722 provided on the case member 720 to support the motor shaft 710, and a second bearing 722. , A stator 730 provided inside the case member 720 and made of a fixed electromagnet, and a rotor 740 rotatably attached to the motor shaft 710. The stepping motor 700 of the present embodiment is a PM (Permanent Magnet) type stepping motor, and is configured such that the motor makes one rotation in 96 steps of a 1-2 phase excitation type. In this embodiment, since the gear ratio between the reel and the motor is 1: 5, the reel makes one rotation in 480 steps (= 5 × 96).

  The motor shaft 710 is a shaft to which a drive gear 618 is attached and outputs power. Hereinafter, the end of the motor shaft 710 to which the drive gear 618 is attached is referred to as an output end 710A, and the opposite end is referred to as a rear end 710B.

  The case member 720 is a bottomed hollow cylindrical body including a substantially cylindrical base portion 720A having one end opened and a lid portion 720B disposed so as to close the opening of the base portion 720A. Case member 720 accommodates stator 730 and rotor 740 therein, and supports motor shaft 710 penetrating from the bottom of base portion 720A to lid portion 720B via first bearing 722 and second bearing 724. ing.

  The first bearing 722 is a substantially cylindrical slide bearing that is disposed substantially at the center of the lid 720B of the case member 720 and rotatably supports the motor shaft 710 near the output end 710A.

  The second bearing 724 is a substantially cylindrical slide bearing that is disposed substantially at the center of the bottom of the base 720A of the case member 720 and rotatably supports the motor shaft 710 near the rear end 710B.

  The stator 730 is disposed so as to surround the rotor 740, and has drive coils wound in two stages, upper and lower (A phase, B phase). In this embodiment, as shown in FIG. 8, the magnetic pole teeth form a triangle (upward is referred to as A-phase and B-phase, downward is referred to as A-phase and B-phase. A-phase and B-phase are electrical angles. A phase relationship of 90 degrees, an A phase and an A-phase, and a B phase and a B-phase have a phase relationship of an electrical angle of 180 degrees), and each magnetic pole (A phase, A-phase, B-phase, and B-phase) has 12 turns. Has become a tooth. FIG. 9 is a diagram showing the arrangement of the magnetic poles of the stator 730. As shown in FIG. 9, the magnetic poles are circumferentially arranged clockwise in the order of A-phase, B-phase, A-phase, and B-phase.

  In the case of the present embodiment, the rotor 740 is formed of a permanent magnet, and has 24 magnetic poles.

  Here, the operation principle of the stepping motor 700 will be described. The stepping motor 700 causes a current to flow through a coil wound around the stator 730 to sequentially magnetize each phase of the stator 730 based on an excitation pattern described later, and attracts the rotor 740 by magnetic force to rotate the rotor 740. It is configured as follows.

  In the 1-2-phase excitation method, the above-described four phases of the stator 730 are, for example, A-phase (one-phase excitation) → A-phase and B-phase (hereinafter, referred to as AB-phase; two-phase excitation) → B-phase (one-phase excitation). ) → A-phase and B-phase (hereinafter, referred to as AB phase; two-phase excitation) → A-phase (one-phase excitation) → A-phase and B-phase (hereinafter, referred to as AB-phase, two phases) Excitation) → B-phase (one-phase excitation) → A-phase and B-phase (hereinafter referred to as AB-phase; two-phase excitation) → A-phase (one-phase excitation) →. Is rotated in a certain direction.

  More specifically, the CPU 304 of the main control unit 300 outputs an on-level pulse signal (for example, a high-level signal) to a phase for exciting the stator 730 of the stepping motor 700 via the drive circuit 322, and simultaneously excites the excitation. A predetermined phase is excited by outputting an off-level pulse signal (for example, a low-level signal) to a phase in which no phase is performed. Thereby, the rotor 740 of the stepping motor 700 is rotated by a predetermined angle (one step). For example, the CPU 304 of the main control unit 300 outputs an on-level pulse signal to the A-phase of the stator 730 of the stepping motor 700 and simultaneously outputs an off-level pulse signal to the B-phase, A-phase, and B-phase. As a result, only the A phase is excited to rotate the rotor by one pulse (one step), and thereafter the excitation is switched in the above-described order to rotate the rotor by a predetermined pulse. In addition, A phase → AB phase → B phase → AB phase → A phase → AB phase → B phase → AB phase (or A phase → AB phase → B phase → AB phase) The rotation of eight pulses (8 steps) of phase → A-phase → AB phase → B phase → AB phase) is hereinafter referred to as one cycle.

  In the present embodiment, as described above, the number of pulses required to rotate the reel once (360 degrees) is set to 480 pulses (60 cycles). Therefore, the rotation angle of the rotor 740 per pulse is about 0.75 degrees (= 360/480).

<Excitation table>
The drive signal output from the CPU 304 to the drive circuit 322 is stored in the ROM 306 as an excitation table. The CPU 304 outputs a designated drive signal by referring to the excitation table. FIG. 10 is a table showing the contents of the excitation table of the present embodiment. The data of each excitation table (data for controlling the rotation of the reel, so also referred to as rotation control data) is composed of six bit data (specifically, A-I0, A-I1, A-Phase, and B-I0). , B-I1, and B-Phase) to represent the phase to be excited and the exciting force. Specifically, the combination of A-I0 and A-I1 indicates the magnitude of the current (excitation force) for exciting the A-phase or A-phase coil. When I1 is 0, 0%, A-I0 is 1, 20% when A-I1 is 0, 0% when A-I0 is 0, and 60% when A-I1 is 1, A-I0 is When 1, A-I1 is 1, it indicates 100%, and when A-Phase is 1, A-phase excitation is shown, and when A-Phase is 0, A-phase excitation is shown. Similarly, the combination of B-I0 and B-I1 indicates the magnitude of the current (excitation force) for exciting the B-phase or B-phase coil, where B-I0 is 0, B-I1 Is 0% when B is 0, 1 when B-I0 is 1, 20% when B-I1 is 0, 60% when B-I0 is 0 and B-I1 is 1, and B-I0 is 1 , B-I1 is 1, indicating 100%, B-Phase being 1, B-phase excitation, and 0 being B-Phase excitation.

  For example, the excitation table “55H” with the table number “B0” has A-I0 of 1, A-I1 of 0, A-Phase of 1, B-I0 of 1, B-I1 of 0, and B-Phase of Since it is 1, it indicates that the AB phase is excited at 20%. Further, the excitation table “06H” having the table number “C1” has A-0 of 0, A-1 of 1, A-Phase of 1, B-I0 of 0, B-I1 of 0, and B-Phase of 0. Since it is 0, it indicates that the A-phase is excited at 60% (the B-phase is 0% and is not excited). Therefore, when switching the table number from “C0” → “C1” → “C2” → “C3” → “C4” → “C5” → “C6” → “C7”, the AB phase → A phase → It is possible to excite each phase by 60% in the order of AB-phase → B-phase → AB-phase → A-phase → AB phase → B phase and rotate the rotor 740 by an angle for one cycle. it can. As described above, in the present embodiment, the rotation of the reel is controlled by outputting the excitation table data (rotation control data) composed of 6 bits to the drive circuit 322 as a drive signal. In the present embodiment, as shown in FIG. 10, an excitation force of 0% is expressed as no excitation, an excitation force of 20% is expressed as weak excitation, an excitation force of 60% is expressed as medium excitation, and an excitation force of 100% is expressed as strong excitation.

<Rotation control table>
FIG. 11 is a table showing the contents of the rotation control table of the present embodiment. The rotation control table is stored in the ROM 306, and stores the contents of the rotation control for each reel control status (specifically, configured by a general-purpose offset counter value, an excitation table, and a holding parameter). The reel control status is information relating to the control state of the reels, which is stored independently for each of the reels 110 to 112, and is information indicating that each of the reels 110 to 112 is in the stopped state. "Stop control state (stop control)", "acceleration state (acceleration control)" indicating that each of reels 110 to 112 is in an accelerated state, and reels 110 to 112 each in a constant speed state. “Constant speed state (constant speed control)” which is information indicating that there is, “pull-in state (pull-in control)” which is information indicating that each of the reels 110 to 112 is in the retracted state,
"Brake state (braking control)" which is information indicating that each of the reels 110 to 112 is in the brake state, and "Special brake" which is information indicating that each of the reels 110 to 112 is in the special brake state. State (special brake control in progress) "is stored.

  In the present embodiment, the constant speed state is further classified into two states having different exciting forces, and a “first constant speed state (during the first constant speed control)” and a first constant speed state that are set immediately after the acceleration state. There is a “second constant speed state (during the second constant speed control)” that is set immediately after the speed state (during the first constant speed control). The first constant speed state is provided to stably rotate the reels 110 to 112 and to save power, and the second constant speed state reduces the exciting force to suppress heat generation of the reels 110 to 112. It is provided in order to. In the present embodiment, in the stop control of the MB gaming state, the “special brake state (during special brake control)” is set only when the number of drawn frames is one, and in other cases, the “brake state (brake state)” is set. (During control) is set (to be described in detail later).

  The slot machine 100 of the present embodiment changes the reel control status from stop control to acceleration control to first constant speed control to second constant speed control to pull-in control to brake control or special brake control to stop. The rotation of the reels 110 to 112 is controlled by selecting the excitation table (rotation control data) corresponding to each reel status by changing the state to the control state.

  For example, when the reel control status is “acceleration control”, as shown in FIG. 11, first, the rotation control data of the excitation table “77H” corresponding to the general-purpose offset counter value “0” is held for “12” holding time, and then The rotation control data of the excitation table “07H” corresponding to the general-purpose offset counter value “1” is held for “12”, and the rotation control data of the excitation table “37H” corresponding to the general-purpose offset counter value “2” is changed to “ The rotation control data of the excitation table “30H” corresponding to the “3” holding time and then the general-purpose offset counter value “3” is sequentially changed from the top row to the bottom row of the table as “3” holding time. Set up. Then, the reels 110 to 112 are accelerated by gradually reducing the holding time of the rotation control data set in order.

  Note that the general-purpose offset counter value is a number indicating the order in which each rotation control data is executed in each reel control status (0 origin), and is a cyclic value returning to 0 after 7. The holding time (holding parameter) indicates a time for holding the set rotation control data, and one holding time indicates one interrupt time (1.563 ms). Therefore, as shown in FIG. 11, during “acceleration control” of the present embodiment, the 1-2 phase 100% excitation (strong excitation) is performed, and it takes 93.780 ms (= 1.563 × 60). It is configured as follows.

  Also, when the reel control status is “under constant speed control”, first, as shown in FIG. 11, the rotation control data of the excitation table “77H” corresponding to the general-purpose offset counter value “0” is held at “1”. Time, then the rotation control data of the excitation table “07H” corresponding to the general-purpose offset counter value “1” is held for “1”, and then the rotation control of the excitation table “37H” corresponding to the general-purpose offset counter value “2” is performed. The rotation control data is sequentially set from the top row to the bottom row of the table, such as data holding time “1”,..., And the rotation control data described in the table is repeated 16 times as one set. That is, the reels are stably rotated at a constant speed by switching the rotation control data that is sequentially set at one holding time and executing 16 sets. As a result, it is configured such that the “during the first constant speed control” of the present embodiment requires 200.064 ms (= 1.563 × 8 × 16 sets) in 100% excitation (strong excitation) in the 1-2 phase. Have been.

  Further, when the reel control status is “second constant speed control in progress”, first, as shown in FIG. 11, the rotation control data of the excitation table “66H” corresponding to the general-purpose offset counter value “0” is held at “1”. Time, then the rotation control data of the excitation table "06H" corresponding to the general-purpose offset counter value "1" is held for "1", and then the rotation control of the excitation table "26H" corresponding to the general-purpose offset counter value "2" The rotation control data is sequentially set from the top row to the bottom row of the table, such as data holding time “1”. That is, the reel is rotated at a constant speed by switching the rotation control data that is sequentially set in one holding time. As a result, during the "second constant speed control" of the present embodiment, the 1-2 phase 60% excitation (medium excitation) state is continued until a stop operation is performed.

  When the reel control status is "during pull-in control", the rotation control data used in "during second constant-speed control" is successively set, but (1) pull-in is performed in the pull-in control in the MB gaming state. When the number of frames is 1, that is, when "special brake control" is performed after the "pull-in control", pull-in control (hereinafter referred to as "special pull-in control"), and (2) other than that, that is, "pull-in control" In the pull-in control (hereinafter referred to as "normal pull-in control") in the case where "brake control" is performed after the step (1), the setting method of the rotation control data is different.

  First, (2) “normal retract control” will be described. From the rotation control data next to the last used rotation control data in “during second constant speed control”, a predetermined number of steps (stop button is operated) The number of steps corresponding to the rest of the pattern at the moment), the number of steps corresponding to the number of frames to be drawn (number of frames to be drawn × 24), and the value of the general-purpose offset counter are set to 0 in sequence. The rotation control data of each excitation table corresponding to No. 7 is sequentially and repeatedly set for each “1” holding time.

  On the other hand, in the case of the (1) “special pull-in control”, the predetermined number of steps (the stop button is operated) from the rotation control data next to the last used rotation control data in “during the second constant speed control” (The number of steps corresponding to the rest of the symbol position at the moment), and the number of steps corresponding to the “1” holding time are sequentially and repeatedly set. , The rotation control data of each excitation table corresponding to “1” is sequentially and repeatedly set for each “1” holding time.

  As described above, during the “pull-in control”, the reels are rotated at a constant speed by sequentially switching the rotation control data that is sequentially set at one holding time, and the state of the 1-2 phase 60% excitation (medium excitation) is performed. Is maintained, but in the case of “special pull-in control”, the “4” holding time is shorter than in the case of “normal pull-in control” (one frame).

  Then, after that, when the reel control status is “under brake control”, first, as shown in FIG. 11, the rotation control data of the excitation table “77H” corresponding to the general-purpose offset counter value of 0 is stored for “50” holding time, Next, the rotation control data of the excitation table “55H” corresponding to the general-purpose offset counter value “1” is set to the rotation control data such as “8” holding time (in the present embodiment, the rotation control data is stopped in the AB phase. ). As described above, when the reel control status is “under brake control”, the phase (AB phase) corresponding to the stop position is obtained by using the rotation control data of the two-phase 100% excitation and then the rotation control data of the two-phase 20% excitation. Is always in an excited state, and the reel is stopped at a predetermined stop position.

  On the other hand, when the reel control status is “under special brake control”, as shown in FIG. 11, first, the rotation control data of the excitation table “55H” corresponding to the general-purpose offset counter value of 0 is held for “10”, then The rotation control data of the excitation table “77H” corresponding to the general-purpose offset counter value “1” is held for “20”, and the rotation control data of the excitation table “55H” corresponding to the general-purpose offset counter value “2” is changed to “ The rotation control data is set such as “1” holding time (in the present embodiment, the rotation is stopped in the AB phase). As described above, when the reel control status is “under special brake control”, the two-phase 20% excitation rotation control data, the two-phase 1000% excitation rotation control data, Using the rotation control data of the phase 20% excitation in order, the phase corresponding to the stop position (AB phase) is always in the excitation state, and the reel is stopped at the predetermined stop position.

  FIG. 12 is a timing chart showing transition of the stop control data after the second constant speed control during the normal pull-in control. FIG. 12 shows an example in which the number of remaining steps ST1 of the symbol when the stop operation is performed is 24, and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 24).

  In this case, the normal pull-in control is started from the time point t1 at which the stop operation is performed, and the time of 24 interrupt time (ST1) corresponding to the rest of the symbol at the time of the stop operation and the number of pull-in frames 1 are reduced. The table numbers “C0” to “C7” are sequentially and repeatedly set one by one for the corresponding 24 interrupt time (ST2), and the normal pull-in control is ended at time t2.

  Next, during “braking control” started from the time point t2, the rotation control data of the table number “D0” (the rotation control data for exciting the AB phase by 100%) is interrupted for 50 times, and then the table number “B0” The rotation control data (rotation control data for exciting the AB phase by 20%) is set for one interruption time, and the reels 110 to 112 are stopped.

  FIG. 13 is a timing chart showing transition of the stop control data after the second constant speed control when the special pull-in control is performed. FIG. 13 shows an example in which the number of remaining steps ST1 of the symbol at the time of the stop operation is 24 and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 20).

  In this case, the special pull-in control is started from the time point t1 at which the stop operation is performed, and the time of 24 interrupt time (ST1) corresponding to the rest of the symbol at the time of the stop operation and the number of pull-in frames 1 are reduced. The table numbers “C0” to “C7” are sequentially and repeatedly set by one interrupt time for the corresponding 20 interrupt times (ST2), and specially at time t3 (four interrupt times before time t2). The retraction control is ended.

  Next, during “special brake control” started at time t3, the rotation control data of table number “B0” (rotation control data for exciting the AB phase by 20%) is interrupted for 10 interruption times, and then the table number “D0” Of the rotation control data (rotation control data for exciting the AB phase by 100%) for 20 interruption times, and then the rotation control data for the table number "B0" (rotation control data for exciting the AB phase by 20%) to 1 interruption time; After setting, the reels 110 to 112 are stopped.

  As described above, in the present embodiment, when performing the special retraction control, the retraction control is terminated four steps before the case where the normal retraction control is performed, and the brake control is performed earlier. As a result, even in the MB gaming state of the slot machine 100 using the reels 110 to 112 having 20 symbols applied to one reel, it is possible to stop not only the bitter but also the one-frame sliding. . That is, various stop modes can be realized even in the MB game state, and it is possible to prevent the appearance of a stop mode that may mislead the player.

<Brake control, special brake control>
Next, the brake control and the special brake control of the present embodiment will be described in detail with reference to FIGS. Here, FIG. 14 is a diagram schematically illustrating the operation of the stepping motor 700 during the brake control, and FIG. 15 is a diagram schematically illustrating the operation of the stepping motor 700 during the special brake control. In order to simplify the explanation, the excitation phase arranged on the stator 730 is reduced to 1/3 in FIGS. FIGS. 14 and 15 show that the excitation is performed in the order of A-phase → AB-layer → B-phase → AB-phase → A-phase → AB phase → B phase → AB phase. A state in which the rotor 740 is rotated clockwise is shown, and a state in which one magnetic pole R of the rotor 740 is stopped in the AB phase is shown. The AB phase at the position where one magnetic pole R stops is denoted by P1, and the AB-phase four steps before P1 is denoted by P2.

  FIG. 14 shows that the AB phase, the A phase,..., The AB phase, and the B phase are sequentially excited clockwise (pull-in control, see FIG. 14A), and then the stop phase AB phase is excited ( Brake control, see FIGS. 14 (b) and (c)), and shows how one magnetic pole R of the rotor 740 is stopped in the AB phase.

  FIG. 14B illustrates a state in which the AB phase is strongly excited using the rotation control data of the table number “D0” (rotation control data for exciting the AB phase by 100%), and FIG. , The AB phase is weakly excited using the rotation control data of the table number “B0” (rotation control data for exciting the AB phase by 20%).

  As described above, the brake control of the present embodiment is a control in which when the magnetic pole R reaches P1, the AB phase is excited to stop the magnetic pole R at P1.

  FIG. 15 shows four steps ahead of the AB-phase after the clockwise excitation to the AB-phase, the A-phase,..., The B-phase, and the AB-phase in sequence (retraction control, see FIG. 15A). 15B, the AB phase, which is the stop position of the rotor 740, is excited (special brake control, see FIGS. 15B, 15C, and 15D) to stop one magnetic pole R of the rotor 740 in the AB phase.

  FIG. 15B shows a state in which the AB phase is weakly excited using the rotation control data of the table number “B0” (rotation control data for exciting the AB phase by 20%), and FIG. A state in which the AB phase is weakly excited using the rotation control data of the table number “D0” (the rotation control data for exciting the AB phase by 100%). FIG. 15D shows the rotation control data of the table number “B0”. (Rotation control data for exciting the AB phase by 20%) shows a state in which the AB phase is weakly excited.

  As described above, the special brake control of the present embodiment is a control in which the AB phase is excited and the one magnetic pole R is stopped at P1 when the magnetic pole R reaches P2 four steps before P1. That is, the special brake control is a control in which one magnetic pole R in P2 is moved to P1 and stopped.

  In the present embodiment, as shown in FIGS. 14 and 15, the AB phase is set to the stop position. Therefore, when the reel is assembled, the inspection sensor is used to set the index sensor so that the AB phase is set to the stop position. Adjusting the reference position.

<Operation>
Next, an operation of the slot machine 100 including the above-described stepping motor 700 will be described.

<Main control unit main processing>
First, the main processing of the main control unit 300 will be described with reference to FIG. FIG. 4 is a flowchart showing the flow of the main processing of the main control unit 300.

  The basic control of the game is performed mainly by the CPU 304 of the main control unit 300, and the CPU 304 repeatedly executes the main process of the main control unit shown in FIG.

  When the power is turned on, first, in step S101, various initial settings are performed. In this initial setting, setting of a stack initial value to a stack pointer (SP) of the CPU 304, setting of inhibition of interrupt, initial setting of the I / O 310, initial setting of various variables stored in the RAM 308, permission of operation to the WDT 314, and initial setting Set values, etc.

  In step S102, a medal insertion / start operation accepting process is executed. Here, the presence / absence of medal insertion is checked, and the winning line display lamp 120 is turned on in response to the medal insertion. Also, a preparation for transmitting a medal insertion command indicating that a medal has been inserted to the first sub-control unit 400 is performed. When the player wins the re-game in the previous game, a process of inserting the same number of medals as the number of medals inserted in the previous game is performed, so that the player does not need to insert medals. Also, it is checked whether or not the start lever 135 has been operated, and if it is determined that the start operation has been performed, the number of inserted medals is determined, and an effective pay line is determined. To obtain the random number. In step S102, preparation is made to transmit a start lever acceptance command indicating that the start lever 135 has been operated to the first sub control unit 400.

  In step S103, a winning combination internal lottery process is performed. In the winning combination internal lottery process, an internal lottery of the winning combination is performed using the random number value acquired in step S102 and the winning combination lottery table stored in the ROM 306. As a result of the winning combination internal lottery process, when any of the winning combinations is internally won, the flag of the winning combination is internally turned on. In this step S103, preparation is made to transmit an internal lottery result command indicating the result of the internal lottery to the first sub-control unit 400.

  In step S104, a reel stop preparation process is performed. In the reel stop preparation processing, reel stop data is selected for each of the reels 110 to 112 based on the result of the winning combination internal lottery processing in step S103 and the like.

  In step S105, a reel rotation start process (to be described in detail later) for starting rotation of all reels 110 to 112 is executed based on the start operation.

  In step S106, it is determined whether or not all the reels have stopped based on the reel rotation control processing of the main control unit timer interrupt processing described later. If all the reels have stopped, the process proceeds to step S107; otherwise, the process returns to step S106.

  In step S107, the winning determination of the symbol stopped by pressing the stop buttons 137 to 139 is performed. Here, if the winning combination corresponding to the internally won winning combination or the winning combination whose flag is being carried over is aligned (displayed) on the activated winning line, it is determined that the winning combination has been won. For example, if “Replay-Replay-Replay” is present on the activated payline, it is determined that a replay has been won. In step S107, preparation is made to transmit a display determination command indicating the result of the winning determination to the first sub-control unit 400.

  In step S108, a medal payout process is performed. In this medal payout process, if any winning combination with a payout has been won, the number of medals corresponding to the winning combination is paid out.

  In step S109, a game state control process is performed. In this game state control processing, control for shifting the game state is performed. For example, in the case of a BB (Big Bonus) winning, a preparation is made so that a BB (Big Bonus) game can be started from the next time. Prepare to start the normal game from the next time. In this step S109, preparation is made to transmit a gaming state command indicating a gaming state to the first sub-control unit 400.

  Thus, one game is completed. Thereafter, the process returns to step S102 and the above-described processing is repeated, whereby the game proceeds. The various commands prepared in the above steps are transmitted in a command setting transmission process (step S1008 in FIG. 18) of a main control unit timer interrupt process described later.

<Reel rotation start processing>
FIG. 17 is a flowchart showing in detail the flow of the reel rotation start processing in step S105 in FIG.

  In step S201, a game time monitoring timer value is obtained. The game time monitoring timer is a timer stored in a specific storage area of the RAM 308 of the main control unit 300, and a time required for one game is set to a predetermined time (for example, a minimum game time of 4.1 seconds). This timer is set for the purpose of limiting the number of game media obtained or lost per unit time and restricting the gambling of the game. A predetermined timer value (for example, a timer value corresponding to 4.1 seconds) is set in the game time monitoring timer in step S203 described later, and each time a timer interrupt process (described later) of the main control unit 300 is executed. Is decremented.

  In step S202, it is determined whether or not the acquired game time monitoring timer value has exceeded 4.1 seconds. If the game time monitoring timer value exceeds 4.1 seconds, the current game may be started, and the process proceeds to step S203. On the other hand, when the game time monitoring timer value does not exceed 4.1 seconds, the process returns to step S201 to repeat the processing. While the process is repeated, the timer value of the game time monitoring timer is decremented for each timer interrupt of the main control unit 300, and when the game time monitoring timer becomes 0, the process proceeds to step S203.

  In step S203, the game time monitoring timer value is reset. Specifically, a timer value corresponding to 4.1 seconds is stored in a specific area of the RAM 308. In the present embodiment, the time when the game time monitoring timer value is set is the start timing of one game. The end timing of one game is when the next game time monitoring timer value is set. In other words, one game is from setting the game time monitoring timer value to setting the next game time monitoring timer value. Further, since the game time monitoring timer value is set every time the rotation of each of the reels 110 to 112 starts, the time from the start of the rotation of each of the reels 110 to 112 to the next start of the rotation of each of the reels 110 to 112 is also set. It can be a single game. Note that the timing of ending one game may be when the game time monitoring timer value becomes 0 and the game state control process of S109 in FIG. 16 ends. In addition, the start timing of one game is set when a valid start lever is received, the end timing of one game is set when a valid bet button operation can be received, and the start lever that is valid when the bet button operation can be received. May be a preparation period for starting the next game.

  In step S204, a reel rotation start command to be transmitted to the first sub control unit 400 is set, and preparation for transmission is performed. The reel rotation start command is a command indicating the start of rotation of the reels 110 to 112.

  In step S205, the status of the left reel 110 is set to "start rotation".

  In step S206, the status of the middle reel 111 is set to "start rotation".

  In step S207, the status of the right reel 112 is set to "start rotation".

  In step S208, the reel control status is set to “acceleration state (acceleration control in progress)”. As described above, the reel control status is information on the control state of the reels, which is independently stored for each of the reels 110 to 112 in a predetermined storage area of the RAM 308 of the main control unit 300, Control state (stop control), "acceleration state (acceleration control)", "first constant speed state (first constant speed control)", "second constant speed state (second constant speed control)" One of the following information is stored: "pull-in state (pull-in control)", "brake state (braking control)", and "special brake state (special brake control)". In step S208, the acceleration start request flag is turned ON. The acceleration start request flag is flag information stored in a predetermined storage area of the RAM 308 of the main control unit 300, and is referred to in an acceleration control process described later.

<Main controller timer interrupt processing>
Next, the main control unit timer interrupt processing executed by the CPU 304 of the main control unit 300 will be described with reference to FIG. FIG. 5 is a flowchart showing the flow of the main control unit timer interrupt processing.

  The main control unit 300 includes a counter timer 312 that generates a timer interrupt signal at a predetermined cycle (in this embodiment, about once every 1.5 ms). The main control unit timer is triggered by the timer interrupt signal. An interrupt process is executed at a predetermined cycle.

  In step S1001, a timer interrupt start process is performed. In the timer interrupt start process, a process of temporarily saving the value of each register of the CPU 304 to the stack area is performed.

  In step S1002, the WDT is periodically (set) so that the count value of the WDT 314 exceeds the initial set value (32.8 ms in the present embodiment) and a WDT interrupt does not occur (do not detect a processing abnormality). In the embodiment, the restart is performed once (about once every 1.5 ms, which is the period of the main control unit timer interrupt).

  In step S1003, an input port state update process is performed. In this input port state update processing, the detection signals of the sensor circuits 320 of the various sensors 318 are input via the input ports of the I / O 310 to monitor the presence or absence of the detection signals, and the detection signals are partitioned in the RAM 308 for each of the various sensors 318. It is stored in the provided signal state storage area.

  In step S1004, various game processes are performed. Specifically, an interrupt status is acquired (various interrupt statuses are acquired based on signals from various sensors 318), and processing according to the status is performed. For example, if the interrupt status is during the medal insertion process, a medal insertion receiving process is performed, and if the interrupt status is the payout process, a medal payout process is performed.

  In step S1005, a timer update process is performed. Various timers are updated in each time unit. In the present embodiment, specifically, the above-described subtraction update of the game time monitoring timer is performed.

  In step S1006, a device monitoring process is performed. In this device monitoring process, first, in step S1003, the signal states of the various sensors 318 stored in the signal state storage area are read, and the presence or absence of an error relating to a medal insertion abnormality and a medal payout abnormality is monitored. Performs error handling. Further, the medal selector 170 (a medal blocker in which a solenoid provided in the medal selector 170 operates), various lamps 338, and various seven-segment (SEG) indicators are set according to the current gaming state.

  In step S1007, when the status of each reel is "start rotation", a reel rotation control process (to be described in detail later) is performed. In this reel rotation control processing, the rotation of the reels is controlled and, based on the plurality of reel stop data candidates selected in step S106 of the main control unit main processing, actual reel stop data is determined in accordance with the stop order and stop state of the reels 110 to 112. After the reel stop data used for the reel stop control is determined, the rotation of the reels 110 to 112 corresponding to the pressed stop buttons 137 to 139 is stopped based on the determined reel stop data.

  In step S1008, a command setting transmission process is performed, and various commands are transmitted to the first sub control unit 400. The output schedule information to be transmitted to the first sub-control unit 400 is composed of 16 bits in the present embodiment, and bit 15 is strobe information (when ON, it indicates that data is set), bit 11 14 to 14 are command types (in this embodiment, a basic command, a start lever reception command, an internal lottery command, a rotation start command for starting rotation of the reels 110 to 112, a stop button for receiving operations of the stop buttons 137 to 139). The reception command, the stop position information command accompanying the stop processing of the reels 110 to 112, the payout number command accompanying the medal payout processing, the payout end command, and the like, and bits 0 to 10 are command data (predetermined information corresponding to the command type). Make up.

  The first sub control unit 400 can determine the effect control according to the change of the game control in the main control unit 300 based on the command type included in the received output schedule information, and is included in the output schedule information. It is possible to determine the effect control content based on the information of the command data.

  In step S1009, an external signal output process is performed. In the external signal output process, the game information stored in the RAM 308 is output to the information input circuit 652 separate from the slot machine 100 via the information output circuit 334.

  In step S1010, it is monitored whether the low voltage signal is on. When the low-voltage signal is on (when the power-off is detected), the process proceeds to step S1012. When the low-voltage signal is off (when the power-off is not detected), the process proceeds to step S1011.

In step S1011, various processes for ending the timer interrupt end process are performed. In this timer interrupt end processing, the values of the registers temporarily saved in step S1001 are set in the original registers. Thereafter, the process returns to the main control unit main process shown in FIG.
On the other hand, in step S1012, a specific variable and a stack pointer for returning to the state at the time of power failure when power is restored are saved as return data in a predetermined area of the RAM 308, and power failure processing such as initialization of input / output ports is performed. Then, the process returns to the main control unit main process shown in FIG.

<Reel rotation control processing>
Next, the reel rotation control processing will be described in detail with reference to FIG. FIG. 19 is a flowchart showing in detail the flow of the reel rotation control process in step S1007 of FIG.

  In step S1101, it is determined whether the operation of the stop buttons 137 to 139 is valid. More specifically, it is determined whether or not the operation of the stop buttons 137 to 139 is valid based on stop button validity information stored in a predetermined area of the RAM 308 and indicating whether or not the operation of the stop buttons 137 to 139 is valid. If the stop button validity information is set, it is determined that the operation of the stop buttons 137 to 139 is valid. The stop button validity information is set in a second constant speed control process described later (see step S1510 in FIG. 23). If the operation of the stop buttons 137 to 139 is valid, the process proceeds to step S1102 to perform a stop button accepting process (to be described in detail later), and then performs the processes of steps S1103 to S1109 for each of the reels 110 to 112. Do. On the other hand, when the operation of the stop buttons 137 to 139 is not valid, the processing of steps S1103 to S1109 is performed for each of the reels 110 to 112.

  In step S1103, index detection information stored in a predetermined area (index sensor storage area) of the RAM 308 is obtained. The index detection information is information indicating whether or not the index sensor 606A has detected the light shielding piece 612D, and is set in a second constant speed control process described later (see step S1508 in FIG. 23).

  In step S1104, reel control information is obtained. Here, the reel control information means the entire information related to the rotation control of the reels 110 to 112, and is stored in a predetermined area of the RAM 308. In the present embodiment, the reel control information includes the values of the above-described reel control status, general-purpose offset counter, reel control status transition counter, and holding counter described below.

  In step S1105, a reel control determination process (to be described in detail later) is performed based on the obtained reel control information.

  In step S1106, it is determined whether the reel drive signal switching request flag is ON. The reel drive signal switching request flag is flag information stored in a predetermined storage area of the RAM 308 of the main control unit 300, and indicates whether to switch the currently set rotation control data. When the reel drive signal switching request flag is ON, the currently set rotation control data is switched, and when the reel drive signal switching request flag is OFF, the currently set rotation control data is not switched. The reel drive signal switching request flag is set in each control process (specifically, an acceleration control process, a brake control process, and a special brake control process, which will be described later) of the above-described reel control determination process. When the reel drive signal switching request flag is ON, the process proceeds to step S1107, and when the reel drive signal switching request flag is OFF, the process proceeds to step S1109.

  In step S1107, rotation control data is acquired based on the acquired reel control status and general-purpose offset counter value. Specifically, the corresponding excitation table (rotation control data) is acquired from the table shown in FIG. 11 based on the reel control status and the general-purpose offset counter value. For example, if the reel control status is “acceleration control” and the general-purpose offset counter value is “0”, the rotation control data of the excitation table “77H” is acquired.

  In step S1108, the rotation control data acquired in step S1108 is set.

  In step S1109, since the content of the reel control information has been changed according to the above-described processing, the reel control information is updated.

<Reel control determination process>
FIG. 20 is a flowchart showing in detail the flow of the reel control determination process in step S1105 of FIG. The reel control determination process is a process of sequentially switching the reel rotation control according to the reel control status. Specifically, the processing is executed in the order of the acceleration control processing, the first constant speed control processing, the second constant speed control processing, the pull-in control processing, the brake control processing, or the special brake control processing.

  In step S1201, a reel control status is obtained.

  In step S1202, it is determined whether or not the obtained reel control status is "stop control". If the obtained reel control status is "stop control", the reel control determination process ends. If the acquired reel control state is not “stop control”, the process advances to step S1203.

  In step S1203, it is determined whether the acquired reel control state is "acceleration control in progress". If the reel control state is "acceleration control", the process proceeds to step S1204, where acceleration control processing (control processing for accelerating the rotation of the reel; details will be described later) is performed. On the other hand, if the reel control state is not “acceleration control”, the process proceeds to step S1205.

  In step S1205, it is determined whether or not the acquired reel control state is “under constant speed control”. If the reel control state is "under constant speed control", the flow advances to step S1206 to perform first constant speed control processing (control processing for maintaining reel rotation at a constant speed; details will be described later). . On the other hand, when the reel control state is not “under the first constant speed control”, the process proceeds to step S1207.

  In step S1207, it is determined whether or not the acquired reel control state is “under second constant speed control”. If the reel control state is "second constant speed control", the flow advances to step S1208 to perform second constant speed control processing (control processing for maintaining the rotation of the reel at a constant speed; details will be described later). . On the other hand, when the reel control state is not “under the second constant speed control”, the process proceeds to step S1209.

  In step S1209, it is determined whether or not the acquired reel control state is “under brake control”. If the reel control state is “under brake control”, the flow advances to step S1210 to perform brake control processing (control processing for stopping rotation of the reel; details will be described later). On the other hand, when the reel control state is not “under brake control”, the flow proceeds to step S1211.

  In step S1211, it is determined whether or not the acquired reel control state is “under special brake control”. If the reel control state is "under special brake control", the flow advances to step S1212 to perform special brake control processing (control processing for stopping the rotation of the reel; details will be described later). On the other hand, when the reel control state is not “under special brake control”, the flow proceeds to step S1213.

  In step S1213, since the reel control state is “pull-in control”, a pull-in control process (a process of pulling the reel to a stop position; details will be described later) is performed.

<Acceleration control processing>
FIG. 21 is a flowchart showing in detail the flow of the acceleration control process in step S1204 in FIG.

  In step S1301, it is determined whether or not there is an acceleration start request based on the acceleration start request flag. Since the acceleration start request flag is set to ON in step S208 of the reel rotation start processing shown in FIG. 17, YES is determined in step S1301 of the first timer interrupt processing (described later). In step S1304, the acceleration start request flag is set to OFF, so that it is determined as NO in step S1301 of the second and subsequent timer interrupt processing.) When there is an acceleration start request, the process proceeds to step S1302, and when there is no acceleration start request, the process proceeds to step S1306.

  In step S1302, the initial value of 0 is set to the value of the reel control status transition counter. Here, the reel control status transition counter is a counter for measuring the number of repetitive sets (cycles) of the rotation control data of eight steps in one cycle, and is repeated three times as shown in FIG. 11 in the present embodiment. And the acceleration control process is terminated.

  In step S1303, the value of the general-purpose offset counter is set to 0, which is the initial value.

  In step S1304, the reel drive signal switching request flag is turned ON. Further, the acceleration start request flag is set to OFF.

  In step S1305, a value of a symbol interval counter (to be described in detail later) is set to a dummy value of 0. The value of the symbol interval counter set in step S1305 is used in a second constant speed control process described later. After the processing in step S1305 ends, the flow advances to step S1317.

  In step S1306, the value of the holding counter is decremented by one. The value of the holding counter is set in step S1317 described below, and is decremented by one in one timer interrupt process. The initial value set in the holding counter in step S1317 is a value of a holding parameter corresponding to the set general offset counter value. For example, as shown in FIG. Is set to 12 in the holding counter as an initial value.

  In step S1307, the reel drive signal switching request flag is set to OFF.

  In step S1308, it is determined whether the value of the subtracted holding counter is 0. If the value of the holding counter is 0, it means that the rotation control data is being switched, so the flow proceeds to step S1309. If the value of the holding counter is not 0, it is not the time of switching the rotation control data, and the acceleration control process ends. I do.

  In step S1309, since the rotation control data is being switched, the reel drive signal switching request flag is set to ON.

  In step S1310, 1 is added to the value of the general-purpose offset counter to set the next rotation control data.

  In step S1311, it is determined whether the value of the added general-purpose offset counter is 8. If the value of the general-purpose offset counter is 8, the rotation control of the set (cycle) has been completed, so the flow advances to step S1311, and if the value of the general-purpose offset counter is not 8, the rotation of the set (cycle) has been completed. Since the control has not been completed, the process proceeds to step S1317.

  In step S1312, an initial value of 0 is set to the general-purpose offset counter value in order to shift to the next set (cycle) of rotation control.

  In step S1313, 1 is added to the value of the reel control status transition counter.

  In step S1314, it is determined whether the value of the added reel control status transition counter is 3. If the value of the reel control status transition counter is 3, the process proceeds to step S1315, and if the value of the reel control status transition counter is not 3, the process proceeds to step S1317.

  In step S1315, since all the rotation controls set during the acceleration control have been performed, the reel control status is set to “under constant speed control”.

  In step S1316, the value of the reel control status transition counter is set to 0, which is an initial value. After the processing in step S1316 ends, the acceleration control processing ends.

  In step S1317, by referring to the rotation control table, the reel control status is “acceleration control”, and the holding parameter value corresponding to the set reel control status transition counter value and the general-purpose offset counter value is acquired and acquired. Set the holding parameter value as the initial value of the holding counter. For example, as shown in FIG. 11, when the reel control status transition counter value is 0 and the general offset counter value is 0, 12 is set as the initial value of the holding counter, and the reel control status transition counter value is 1 and the general offset counter value is In the case of 7, 1 is set as the initial value of the holding counter. After the processing in step S1317 ends, the acceleration control processing ends.

<First constant speed control process>
FIG. 22 is a flowchart showing the details of the first constant speed control process in step S1206 of FIG.

  In step S1401, 1 is added to the value of the general-purpose offset counter. That is, in the first constant speed control process, as shown in FIG. 11, since the rotation control data is switched every one interrupt time, the value of the general-purpose offset counter is incremented every time the timer interrupt process is performed. Since the reel drive signal switching request flag is set to ON in step S1309 of the acceleration control process, no switching process is performed. During the two constant speed control processing, it is kept ON. Therefore, in the reel rotation control processing of FIG. 19, rotation control data corresponding to the added general-purpose offset counter value is set for each timer interrupt processing (see step S1108 of FIG. 19).

  In step S1402, it is determined whether the value of the added general-purpose offset counter is 8. If the value of the general-purpose offset counter is 8, the flow advances to step S1403 to shift to the rotation control of the next set (cycle). If the value of the general-purpose offset counter is not 8, the flow proceeds to step S1403. Since the rotation control has not ended, the first constant speed control process ends.

  In step S1403, the value of the general-purpose offset counter is set to 0, which is the initial value, in order to shift to the next set (cycle) of rotation control.

  In step S1404, 1 is added to the value of the reel control status transition counter.

  In step S1405, it is determined whether or not the value of the added reel control status transition counter is 16. If the value of the reel control status transition counter is 16, since 16 sets of rotation control have been completed (see FIG. 11), the process proceeds to step S1406, and if the value of the reel control status transition counter is not 16, the flow proceeds to step S1406. The constant speed control process ends.

  In step S1406, since all the rotation controls set during the first constant speed control have been performed, the reel control status is set to "second constant speed control in progress".

<Second constant speed control process>
FIG. 23 is a flowchart showing in detail the second constant speed control process in step S1208 of FIG. The second constant speed control process mainly performs a process of tracking the symbol position on the reel. The symbol position is monitored using two counters, a "symbol number counter" and a "symbol interval counter", so that the main control unit 300 grasps the symbol position of the reel. Here, the "symbol number counter" and the "symbol interval counter" will be described.

  FIG. 4 is also a diagram showing the relationship between the symbol number counter and the symbol interval counter. The symbol number counter is a counter for storing and holding a symbol located in the middle stage of the symbol display window 113 as a reference position. For example, with respect to the left reel 110, the chance symbol at the upper end of the symbol row of the left reel 110 is used as a reference. The counting starts when the index sensor 606A passes through the light shielding piece 612D. Each symbol and the count value are associated in advance, and the main control unit 300 identifies the symbol stopped and displayed on the symbol display window 113 from the symbol number counter value at the time of reel stop, and makes a winning determination. it can. The symbol interval counter is the number of drive pulses per symbol (the number of timer interrupt processing), and is 24 (480 drive pulses in total). The main control unit 300 sets the number of drive pulses per symbol in the symbol interval counter, subtracts the number for each drive pulse output, and updates the symbol number counter by one when the value of the symbol interval counter becomes zero. I have to.

  In step S1501, 1 is added to the value of the general-purpose offset counter. That is, in the second constant speed control process, as shown in FIG. 11, since the rotation control data is switched every one interruption time, the value of the general-purpose offset counter is incremented every time the timer interruption process is performed. Further, since the reel drive signal switching request flag is still ON, in the reel rotation control processing of FIG. 19, rotation control data corresponding to the added general-purpose offset counter value is set for each timer interruption processing (FIG. 19). 19, see step S1108).

  In step S1502, it is determined whether the value of the added general-purpose offset counter is 8. If the value of the general-purpose offset counter is 8, the flow advances to step S1503 to shift to the rotation control of the next set (cycle). If the value of the general-purpose offset counter is not 8, the flow proceeds to step S1503. Since the rotation control has not been completed, the process proceeds to step S1504.

  In step S1503, the value of the general-purpose offset counter is set to 0, which is the initial value, in order to shift to the next set (cycle) of rotation control.

  In step S1504, the value of the symbol interval counter is decremented by one. That is, the value of the symbol interval counter is decremented every one interruption time.

  In step S1505, it is determined whether or not the value of the subtracted symbol interval counter is 0. When the value of the symbol interval counter is 0, the process proceeds to step S1506, and when the value of the symbol interval counter is not 0, the process proceeds to step S1508.

  In step S1506, if the value of the symbol interval counter is 0, the symbol is replaced with the next symbol, so the initial value of 24 is set as the value of the symbol interval counter.

  In step S1507, the value of the symbol number counter is decremented by one in order to update to the next symbol.

  In step S1508, the detection result of the index sensor stored in a predetermined storage area of the RAM 308 is obtained. The detection result of the index sensor 606A is determined to be detected when the passage of the light shielding piece 612D provided at the position where the symbol number counter value is 0 and the symbol interval counter value is 0 is detected.

  In step S1509, the process proceeds to step S1510 if the obtained detection result of the index sensor is detected, and proceeds to step S1514 if not detected.

  In step S1510, since the symbol position of the reel has been searched, stop button valid information is set.

  In step S1511, the initial value 24 is set as the value of the symbol interval counter.

  In step S1512, the value of the symbol number counter is set to 0 which is an initial value.

  In step S1513, the value of the step-out detection counter is set to 0 which is an initial value. After the processing in step S1513 ends, the second constant speed control processing ends.

  In step S1514, a step-out detection process is performed based on the value of the step-out detection counter. In the step-out detection process, when it is determined that the step-out is performed, the acceleration control process is performed again. After the processing in step S1514 ends, the second constant speed control processing ends.

<Stop button reception processing>
FIG. 24 is a flowchart showing the stop button accepting process in step S1102 of FIG. 19 in detail. The stop button receiving process is executed after the stop button validity information is set in a state where the operation of the stop buttons 137 to 139 can be received, that is, in the second constant speed control process shown in FIG. It is. The stop button accepting process is a process of determining the corresponding reel stop position based on the operation of the stop buttons 137 to 139.

  In step S1601, stop reception information is acquired. Here, the stop reception information is a part of the reel control information, and means all information necessary for the determination of the stop reception.

  In step S1602, a reel that can be stopped is determined from the acquired stop reception information and set as stopable reel information (for example, when it is determined that the left reel 110 is a reel that can be stopped, the left reel 110 is displayed as a stop reel). Set).

  In step S1603, it is determined whether a stop button corresponding to the reel corresponding to the set stoppable reel information has been received. If a stop button has been received, the process proceeds to step S1604. If a stop button has not been received, the process proceeds to step S1607.

  In step S1604, data on a reel to be stopped (stop reel data) is acquired.

  In step S1605, a pull-in counter setting process (to be described in detail later) is performed.

  In step S1606, since the stop button has been received, the status of the reel for which the stop operation has been performed is updated to "stop".

  In step S1607, the stoppable reel information is cleared. This is because the reels that can be stopped are changed by the pull-in counter setting process in step S1605 (for example, if the pull-in counter setting process is performed on the left reel that can be stopped, the left reel can be stopped). Not a reel).

  In step S1608, the stop button LED information is updated according to the stoppable reel information. This is to update the LED information of the stop button according to whether or not each reel can be stopped. For example, when the stop button is pressed, blue is set for the reel that can be stopped. , Red color.

<Retraction counter setting processing>
FIG. 25 is a flowchart showing the details of the pull-in counter setting process in step S1605 of FIG.

  In step S1701, the value of the symbol number counter is obtained, and the position where the stop operation is performed is detected.

  In step S1702, the number of drawn frames is acquired from the selected reel stop control data based on the position where the stop operation was performed.

  In step S1703, the value of the symbol interval counter is acquired, and the number of remaining interrupts is calculated. Here, the number of remaining interrupts is a value obtained by subtracting the value of the symbol interval counter from 24. For example, in the pull-in control shown in FIGS. 11 and 12, 24 is the remaining number of interrupts.

  In step S1704, it is determined whether or not the stop target reel is the left reel 110. If the stop target reel is the left reel 110, the process proceeds to step S1705; otherwise, the process proceeds to step S1707.

  In step S1705, it is determined whether the game is in the MB gaming state. If the game is in the MB game state, the process proceeds to step S1706; otherwise, the process proceeds to step S1707.

  In step S1706, it is determined whether or not the number of drawn frames is one. If the number of drawn frames is 1, the process proceeds to step S1708; otherwise, the process proceeds to step S1707.

  In step S1707, a normal pull-in counter process is performed to perform the normal pull-in control described above. That is, (1) when the stop target reel is not the left reel 110, (2) when it is not the MB gaming state, (3) when it is the MB gaming state and the number of drawn frames of the left reel 110 of the stop target reel is 0, Performs a normal pull-in counter setting process. More specifically, (A) when the number of frames to be drawn is 0, the number of remaining interrupts acquired in step S1703 is set in the pull-in counter, and (B) when the number of frames to be drawn is 1 to 4, The total value obtained by adding the multiplication value obtained by multiplying the number of frames to be drawn by 24 to the number of remaining interrupts obtained in step S1703 is set in the pull-in counter. For example, in the pull-in control shown in FIG. 12, since the number of pull-in frames is 1, 48 is set in the pull-in counter.

  In step S1708, a special attraction counter setting process is performed to perform the above-described special attraction control. That is, when the number of drawn frames of the left reel 110, which is the stop target reel, is one in the MB gaming state, a special pull-in counter setting process is performed. Specifically, the total value obtained by adding 20 to the remaining number of interrupts acquired in step S1703 is set in the pull-in counter. For example, in the pull-in control shown in FIG. 13, since the number of drawn-in frames is 1, 44 is set in the pull-in counter.

  In step S1709, the reel control status is set to "pull-in control".

<Retraction control processing>
FIG. 26 is a flowchart illustrating the pull-in control process in step S1213 of FIG. 20 in detail. Here, the pull-in control process means that when the reels are stopped, the reels are moved from the symbol position where the stop buttons 137 to 139 are operated to a predetermined number of frames (in order to realize stop control according to the result of the internal lottery). In the present embodiment, it refers to a process of sliding and stopping (0 to 4 frames except during MB, 0 to 1 frame during MB). As a result, for the winning combination internally won in the internal lottery or the so-called winning combination with the flag being carried over, it is permissible that the corresponding symbol combinations are displayed together. Are not displayed together.

  In step S1801, 1 is added to the value of the general-purpose offset counter. That is, in the pull-in control process, as shown in FIGS. 11 to 13, the rotation control data is switched every one interrupt time, so that the value of the general-purpose offset counter is updated every timer interrupt process. Further, since the reel drive signal switching request flag is still ON, in the reel rotation control processing of FIG. 19, rotation control data corresponding to the added general-purpose offset counter value is set for each timer interruption processing (FIG. 19). 19, see step S1108).

  In step S1802, it is determined whether the value of the added general-purpose offset counter is 8. If the value of the general-purpose offset counter is 8, the remaining rotation control of the set (cycle) has been completed, and the flow advances to step S1803. If the value of the general-purpose offset counter is not 8, the set (cycle) Since the remaining rotation control has not been completed, the process proceeds to step S1803.

  In step S1803, the value of the general-purpose offset counter is set to 0, which is the initial value.

  In step S1804, the value of the pull-in counter is updated. Specifically, the value of the pull-in counter is decremented by one.

  In step S1805, it is determined whether or not the updated value of the pull-in counter is 0. If the value of the pull-in counter is 0, the process proceeds to step S1806. If the value of the pull-in counter is not 0, the pull-in control process ends.

  In step S1806, it is determined whether or not the stop target reel is the left reel 110. If the stop target reel is the left reel 110, the process proceeds to step S1807; otherwise, the process proceeds to step S1809.

  In step S1807, it is determined whether the game is in the MB gaming state. If the game is in the MB gaming state, the process proceeds to step S1808; otherwise, the process proceeds to step S1809.

  In step S1808, it is determined whether the number of drawn frames is one. If the number of drawn frames is 1, the process proceeds to step S1811; otherwise, the process proceeds to step S1809.

  In step S1809, since the value of the pull-in counter has reached 0 and the stop position has been reached, the reel control status is set to "under brake control". That is, the value of the pull-in counter is 0, (1) the stop target reel is not the left reel 110, (2) the MB game state is not, or (3) the MB game state is the left reel of the stop target reel. In the case where the number of drawn frames of 110 is 0, the reel control status is set to “under brake control”.

  In step S1810, an initial value of 50 is set as the value of the holding counter. Here, the set holding counter value 50 is a holding time of the rotation control data when the general-purpose offset counter value is 0 when the reel control status is “under brake control” (see FIG. 11). After the processing in step S1810 ends, the pull-in control processing ends.

  On the other hand, in step S1811, since the value of the pull-in counter has become 0, the reel control status is set to "under special brake control". That is, when the value of the pull-in counter is 0 and the number of pull-in frames of the left reel 110 of the stop target reel is 1 in the MB gaming state, the reel control status is set to “under special brake control”.

  In step S1812, an initial value of 10 is set as the value of the holding counter. Here, the set holding counter value 10 is the holding time of the rotation control data when the general-purpose offset counter value is 0 when the reel control status is “under special brake control” (see FIG. 11). After the processing in step S1810 ends, the pull-in control processing ends.

<Brake control processing>
FIG. 27 is a flowchart showing details of the brake control process in step S1210 of FIG.

  In step S1901, 1 is subtracted from the value of the holding counter. The value of the holding counter is initialized in step S1810 in FIG. 26 described above or step S1909 described later, and is decremented by 1 in one timer interrupt process. Note that the initial value set in the holding counter in step 1810 or step S1909 is the value of the holding parameter corresponding to the set general offset counter value. For example, as shown in FIG. In the case of 0, 50 is set to 1 and in the case of 1, 1 is set to the holding counter.

  In step S1902, the reel drive signal switching request flag is set to OFF.

  In step S1903, it is determined whether or not the value of the subtracted holding counter is 0. If the value of the holding counter is 0, it means that the rotation control data is being switched, so the process proceeds to step S1904. If the value of the holding counter is not 0, it is not the time of switching the rotation control data, and the brake control process is executed. finish.

  In step S1904, since the rotation control data is being switched, the reel drive signal switching request flag is set to ON.

  In step S1905, 1 is added to the value of the general-purpose offset counter to set the next rotation control data.

  In step S1906, it is determined whether the value of the added general-purpose offset counter is 2. If the value of the general-purpose offset counter is 2, the rotation control in the brake control has been completed, and the process advances to step S1907. If the value of the general-purpose offset counter is not 2, the rotation control in the brake control has not been completed. Then, the process proceeds to step S1909.

  In step S1907, since all the rotation controls set during the brake control have been performed, the reel control status is set to "reel stop control in progress".

  In step S1908, the reel drive signal switching request flag is set to OFF. After the processing in step S1908 ends, the brake control processing ends.

  In step S1909, the rotation control table is referred to, the reel control status is “braking control”, the holding parameter value corresponding to the set general-purpose offset counter value is obtained, and the obtained holding parameter value is stored in the holding counter. Set as the initial value. For example, as shown in FIG. 11, when the general-purpose offset counter value is 1, 1 is set as the initial value of the holding counter. After the processing in step S1909 ends, the brake control processing ends.

<Special brake control processing>
FIG. 28 is a flowchart showing the special brake control process in step S1212 of FIG. 20 in detail.

  In step S2001, 1 is subtracted from the value of the holding counter. The value of the holding counter is initialized in step 1812 of FIG. 26 described above or step S2009 described later, and is decremented by 1 in one timer interrupt process. Note that the initial value set in the holding counter in step 1812 or step S2009 is the value of the holding parameter corresponding to the set general offset counter value. For example, as shown in FIG. In the case of 1, the holding counter is set to 20 in the case of 1.

  In step S2002, the reel drive signal switching request flag is set to OFF.

  In the step S2003, it is determined whether or not the value of the subtracted holding counter is 0. If the value of the holding counter is 0, it means that the rotation control data is being switched, so the process proceeds to step S2004. If the value of the holding counter is not 0, it is not the time of switching the rotation control data, and the special brake control process is performed. To end.

  In step S2004, since the rotation control data is being switched, the reel drive signal switching request flag is set to ON.

  In step S2005, 1 is added to the value of the general-purpose offset counter to set the next rotation control data.

  In step S2006, it is determined whether the value of the added general-purpose offset counter is 3. If the value of the general-purpose offset counter is 3, the rotation control in the special brake control has been completed, so the process proceeds to step S2007. If the value of the general-purpose offset counter is not 3, the rotation control in the brake control has not been completed. Therefore, the process proceeds to step S2009.

  In step S2007, since all the rotation controls set during the special brake control are performed, the reel control status is set to "reel stop control in progress".

  In step S2008, the reel drive signal switching request flag is set to OFF. After the processing in step S2008 ends, the brake control processing ends.

  In step S2009, the rotation control table is referred to, the reel control status is “special brake control is in progress”, the holding parameter value corresponding to the set general-purpose offset counter value is obtained, and the obtained holding parameter value is stored in the holding counter. Set as the initial value of. For example, as shown in FIG. 11, when the general-purpose offset counter value is 1, 20 is set as the initial value of the holding counter. After the processing in step S2009 ends, the special brake control processing ends.

<Process of First Sub-Control Unit 400>
The processing of the first sub control unit 400 will be described with reference to FIG. FIG. 7A is a flowchart of a main process executed by the CPU 404 of the first sub control unit 400. FIG. 4B is a flowchart of a command input process of the first sub-control unit 400, and FIG. 4C is a flowchart of a command reception interrupt process of the first sub-control unit 400, and FIG. 12 is a flowchart of the timer interrupt processing of the first sub control unit 400.

  When the power is turned on, first, an initialization process is executed in step S3001. In this initialization process, initialization of input / output ports, initialization of a storage area in the RAM 408, and the like are performed.

  In step S3002, it is determined whether or not the timer variable is 10 or more. This process is repeated until the timer variable becomes 10. When the timer variable becomes 10 or more, the process proceeds to step S3003.

  In step S3003, 0 is substituted for the timer variable.

  In step S3004, a first sub-control unit command input process (to be described in detail later) is performed. In the first sub control unit command input process, it is determined whether a command has been received from the main control unit 300.

  In step S3005, effect update processing is performed. For example, when there is a new command in step S3004, the effect data is read from the ROM 406 based on the result of each event process (for example, effect setting process, game state control process, etc.) corresponding to the command. When the effect data needs to be updated, the effect data of each effect device (speaker, lamp, liquid crystal image display device, shutter, etc.) is updated.

  In step S3006, a sound control process is performed. In the sound control process, if the effect data read in step S3005 includes a command to the sound source IC 418, the command is output to the sound source IC 418.

  In step S3007, a lamp control process is performed. In the lamp control process, when the effect data read in step S3005 includes a command for various lamps 420, the command is output to the drive circuit 422.

  In step S3008, an information output process is performed. In the information output process, if there is a control command to be transmitted to the second sub-control unit 500 in the effect data read in step S3005, a setting for outputting this control command is performed, and the process returns to step S3002. As a result, the set control command is transmitted to the second sub control unit 500.

  Next, the command input processing of the first sub control unit 400 will be described with reference to FIG. The first sub-controller 400 command input process is a flowchart showing the flow of the first sub-controller 400 command input process of step S3004 in FIG.

  In step S3101, it is determined whether there is an unprocessed command in the command storage area of the RAM 408. If there is an unprocessed command, the process proceeds to step S3102. If there is no unprocessed command, the first sub control unit 400 command input process ends.

  In step S3102, the process jumps to a process corresponding to the unprocessed command. For example, when the unprocessed command is a medal insertion command, a medal insertion process (description is omitted), when the start lever is received command, a start lever reception process (description is omitted), and when an internal lottery command is issued, The internal lottery processing (details will be described later), the stop button reception processing (details are omitted) in the case of a stop button reception command, the display determination processing (details will be described later) in the case of a display determination command ), In the case of a game state command, the process jumps to a game state control process (the description is omitted).

  Next, the command reception interrupt processing of the first sub control unit 400 will be described with reference to FIG. The command reception interrupt process is a process executed when the first sub control unit 400 detects a strobe signal output from the main control unit 300. In step S3201 of the command reception interrupt processing, the command output by the main control unit 300 is stored as an unprocessed command in a command storage area provided in the RAM 408.

  Next, the first sub-controller timer interrupt processing executed by the CPU 404 of the first sub-controller 400 will be described with reference to FIG. The first sub-control unit 400 includes a hardware timer that generates a timer interrupt at a predetermined cycle (once every 2 ms in the present embodiment). Execute in the cycle of

  In step S3301, 1 is added to the value of the timer variable storage area of the RAM 408 described in step S3002 in the first sub-controller main process shown in FIG. Therefore, in step S3002, the value of the timer variable is determined to be 10 or more every 20 ms (2 ms × 10).

  In step S3302, an effect of updating the effect random number is performed.

<Modification of First Embodiment>
In the brake control of the first embodiment, the rotation control data is set in the order of strong excitation (50 interruption times) → weak excitation (1 interruption time) (see FIG. 11), but the present invention is not limited to this. For example, non-excitation may be inserted between strong excitation (50 interruption times) and weak excitation (1 interruption time), and rotation control data may be set in the order of strong excitation → non-excitation → weak excitation. . As described above, if the same phase (AB phase) is continuously excited, there may be a non-excitation period on the way.

  In the special brake control of the first embodiment, the rotation control data is set in the order of weak excitation (10 interrupt times) → strong excitation (20 interrupt times) → weak excitation (1 interrupt time). It is not limited to this. For example, non-excitation may be performed instead of strong excitation, and the rotation control data may be set in the order of weak excitation → non-excitation → weak excitation. As described above, if the same phase (AB phase) is continuously excited, there may be a non-excitation period on the way.

[Second embodiment]
<Rotation control table>
FIG. 30 is a table showing the contents of the rotation control table of the second embodiment. As compared with the first embodiment, the contents of the rotation control table when the reel control status is “brake control state (during brake control)” and “special brake control state (during special brake control)” are different. In the second embodiment, the setting conditions of “during brake control” and “during special brake control” are the same as those in the first embodiment, and only when the number of drawn frames is one in the pull-in control in the MB gaming state. “Under special brake control” is set, otherwise “under brake control” is set. Further, when “special brake control is being performed” is set, the pull-in control is terminated in a phase four steps earlier than when “braking control is being performed” is the same as in the first embodiment. . Hereinafter, configurations and operations different from those of the first embodiment will be described.

  In the first embodiment, when the reel control status is “under brake control” and “under special brake control”, the phase corresponding to the stop position is always in an excited state to stop the reel, but in the second embodiment, , “Under brake control” and “under special brake control”, a non-excitation state (excitation release state) is provided to reduce the load on the stepping motor 700 of the reel at the time of stop and reduce the bounce at the stop position. .

  Specifically, during the "braking control", as shown in FIG. 30, first, the rotation control data of the excitation table "55H" corresponding to the general-purpose offset counter value of 0 is set to "10" holding time, and then the general-purpose offset counter value is set to "10". The rotation control data of the excitation table "44H" corresponding to the offset counter value "1" is held for "8", and the rotation control data of the excitation table "55H" corresponding to the general-purpose offset counter value "2" is finally set to "1". The rotation control data is set such as the holding time (in the present embodiment, the rotation is stopped in the AB phase). As described above, when the reel control status is “under brake control”, the rotation control data of two-phase 20% excitation, the rotation control data of two-phase 0% excitation, and finally the rotation control data of two-phase 20% excitation are used. Thus, the reel is stopped at a predetermined stop position. The rotation control with non-excitation during the brake control is a feature of the second embodiment, and will be described later in detail.

  FIG. 31 is a timing chart showing transition of stop control data after the second constant speed control when the normal pull-in control (brake control) is performed. FIG. 31 shows an example in which the number of remaining steps ST1 of the symbol when the stop operation is performed is 24, and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 24).

  In this case, during "braking control" started from time t2, the rotation control data of table number "B0" (rotation control data for exciting the AB phase by 20%) is interrupted for 10 interruption times, and then the table number "A0" ) Of rotation control data (rotation control data for exciting the AB phase by 0%) for 8 interrupt times, and finally, the rotation control data of table number "B0" (rotation control data for exciting the AB phase by 20%) to the interruption time of 1 interrupt After setting the time, the reels 110 to 112 are stopped.

  On the other hand, during the "special brake control", as shown in FIG. 30, first, the rotation control data of the excitation table "55H" corresponding to the general-purpose offset counter value of 0 is held for "15", and then the general-purpose offset counter is set. The rotation control data of the excitation table "44H" corresponding to the value "1" is held for "10", and the rotation control data of the excitation table "55H" corresponding to the general-purpose offset counter value of 2 is held for "1". The rotation control data is set as follows (in the present embodiment, the rotation is stopped in the AB phase). As described above, when the reel control status is “under special brake control”, the rotation control data of the two-phase 20% excitation, the rotation control data of the two-phase 0% excitation, and finally the rotation control data of the two-phase 20% excitation are transmitted. The reel is stopped at a predetermined stop position. The rotation control with the non-excitation during the special brake control is a feature of the second embodiment, and will be described later in detail.

  FIG. 32 is a timing chart showing transition of stop control data after the second constant speed control when the special pull-in control (special brake control) is performed. FIG. 32 shows an example in which the number of remaining steps ST1 of the symbol at the time of the stop operation is 24, and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 20).

  In this case, during “special brake control” started at time t3, the rotation control data of the table number “B0” (the rotation control data for exciting the AB phase by 20%) is applied for 15 interruption times, and then the table number “ The rotation control data of A0 ”(rotation control data for exciting the AB phase by 0%) is divided by 10 interruption times, and finally the rotation control data of table number“ B0 ”(rotation control data for exciting the AB phase by 20%) is reduced by 10%. The reels 110 to 112 are stopped after setting the loading time.

<Brake control, special brake control>
Next, the brake control and the special brake control of the second embodiment will be described in detail with reference to FIGS. Here, FIG. 33 is a diagram schematically illustrating the operation of the stepping motor 700 during the brake control, and FIG. 34 is a diagram schematically illustrating the operation of the stepping motor 700 during the special brake control. In order to simplify the explanation, the excitation phase arranged on the stator 730 is reduced to 1/3 in FIGS. FIGS. 33 to 34 show that the excitation is performed in the order of A-phase → AB-layer → B-phase → AB-phase → A-phase → AB phase → B phase → AB phase. A state in which the rotor 740 is rotated clockwise is shown, and a state in which one magnetic pole R of the rotor 740 is stopped in the AB phase is shown. The AB phase at the position where one magnetic pole R stops is denoted by P1, the AB-phase four steps before P1 is P2, the AB phase eight steps before P1 is P3, and the AB phase eight steps before P1 is P4 than P3. The AB-phase before the step (12 steps before P1) is denoted as P4.

  In the brake and the special brake control of the second embodiment, as shown in FIGS. 33 and 34, when one magnetic pole R of the rotor 740 is stopped in the AB phase, the excitation is not performed for a predetermined period after the excitation of the AB phase. In this state, one magnetic pole R of the rotor 740 reaches the stop position AB phase after rotating by inertia. For this reason, since the one magnetic pole R reaches the AB phase which is the stop position in a state where the speed is reduced, the load on the stepping motor 700 is reduced.

  FIG. 33 shows that after the AB phase, the A phase,..., The AB phase, and the B phase are sequentially excited in the clockwise direction (retraction control, see FIG. 33A), the AB phase which is the stop position is first excited, The non-excitation state is followed by exciting the AB phase as the stop position (brake control, see FIGS. 33B to 33D) to stop one magnetic pole R of the rotor 740 in the AB phase.

  More specifically, in the brake control, first, the AB phase excitation is performed for 10 interruption times from the time when one magnetic pole R passes through P3, so that as shown in FIG. After passing through the corresponding position P3, one magnetic pole R is attracted to the AB phase at the position P3 and is decelerated until reaching the vicinity of the position P2 corresponding to the AB-phase. In the brake control, after that, no excitation is performed for 8 interruption times, so that as shown in FIG. 33C, one magnetic pole R passing through the position P2 is stopped at the decelerated speed. Since the AB phase is excited when the magnetic pole R reaches the AB phase which is P1 and the one magnetic pole R is near the stop position P1, the rotor 740 can be smoothly stopped at the stop position P3, and the stepping motor 700 at the time of stop can be stopped. Load can be reduced.

  As described above, the brake control of the second embodiment repeats excitation and non-excitation of the AB phase from the time when one magnetic pole R reaches P3 eight steps before P1, and moves the one magnetic pole R at P3 to P1. It is controlled to stop.

  FIG. 33B shows a state in which the AB phase is weakly excited using the rotation control data of the table number “B0” (rotation control data for exciting the AB phase by 20%), and FIG. 33A, the rotation control data of the table number “A0” (rotation control data for exciting the AB phase by 0%) is used, and FIG. 33D shows the rotation control data (AB) of the table number “B0”. FIG. 6 shows a state in which the AB phase is weakly excited using rotation control data for exciting the phase by 20%).

  In FIG. 34, after the phases AB, A,..., B-phase, and AB-phase are sequentially excited clockwise (pull-in control, see FIG. 34A), the AB phase which is the stop position is first excited. Next, non-excitation is performed, and then the AB phase that is the stop position is excited (special brake control, see FIGS. 34B to 34E) to stop one magnetic pole R of the rotor 740 in the AB phase. .

  More specifically, in the special brake control, first, the AB phase excitation is performed for 15 interruption times from the time when one magnetic pole R passes through P4 corresponding to the AB-phase. As shown in ()), after one magnetic pole R passes through the position P3 corresponding to the AB phase, until one magnetic pole R reaches the vicinity of the position P2 corresponding to the AB-phase, the one magnetic pole R is attracted to the AB phase at the position P3. , Is to be decelerated. In the special brake control, after that, no excitation is performed for 10 interruption times, so that one magnetic pole R passing through the position P2 stops at the decelerated speed as shown in FIG. Since the AB phase is excited when the magnetic pole R reaches the AB phase at the position P1 and the magnetic pole R is near the stop position P1, the rotor 740 can be smoothly stopped at the stop position P3. Can be reduced.

  As described above, the special brake control according to the second embodiment repeats excitation and non-excitation of the AB phase from when the one magnetic pole R reaches P4 12 steps before P1, and moves the one magnetic pole R at P4 to P1. Control.

  34 (b) and (c) show a state in which the AB phase is weakly excited using the rotation control data of table number "B0" (rotation control data for exciting the AB phase by 20%). FIG. 34D shows a state in which non-excitation is performed using rotation control data of table number “A0” (rotation control data for exciting the AB phase by 0%). FIG. 34E shows a rotation of table number “B0”. A state is shown in which the AB phase is weakly excited using control data (rotation control data for exciting the AB phase by 20%).

  In this embodiment, as shown in FIGS. 33 and 34, the AB phase eight steps ahead of the pull-in position is set as the stop position. Therefore, when the reel is assembled, the inspection machine is used for eight steps (one cycle). ) The reference position of the index sensor is adjusted so that the preceding AB phase is at the stop position.

<Modification of Second Embodiment>
In the second embodiment, in the brake control and the special brake control, the rotation control data having the same excitation force (the rotation control data for exciting the AB phase by 20%) is used, but the rotation control data having the same excitation force is used. It is not necessary. For example, in the brake control and the special brake control, rotation control data having different excitation powers even in the case of weak excitation (rotation control data for exciting the AB phase by 20%, rotation control data for exciting the AB phase by 30%, etc.) are respectively included. It may be used.

  In the second embodiment, in the brake control and the special brake control, the rotation control data is set in the order of weak excitation → non-excitation → weak excitation (see FIG. 30). However, the present invention is not limited to this. For example, strong excitation may be inserted between weak excitation and non-excitation, and rotation control data may be set in the order of weak excitation → strong excitation → non-excitation → weak excitation. In addition, there may be no non-excitation, and the rotation control data may be set in the order of weak excitation → weak excitation. Further, the weak excitation may be set after the weak excitation → non-excitation set is repeated a plurality of times. For example, the rotation control data may be set in the order of weak excitation → non-excitation → weak excitation → non-excitation → weak excitation. As described above, the magnitude of the exciting force does not matter as long as the same phase (AB phase) is continuously excited. Of course, even in such a case, the total time for setting the weakly-excited rotation control data in the special brake control is longer than the total time for setting the weakly-excited rotation control data in the brake control. I have.

[Third embodiment]
In the brake control and the special brake control of the first embodiment and the second embodiment, the case where the one magnetic pole R of the rotor 740 of the stepping motor 700 is stopped while being fixed to the AB phase has been described. Not limited. For example, the rotor 740 of the stepping motor 700 may be stopped by exciting all of the phases A, B, A-, and B-. Hereinafter, exciting all the phases A, B, A- and B-phase is also referred to as all-phase excitation. In the third embodiment, a method of stopping the rotor 740 of the unipolar drive stepping motor 700 by all-phase excitation will be described.

<Excitation table>
FIG. 35 is a table showing the contents of the excitation table of the third embodiment. The data of each excitation table (which is data for controlling the rotation of the reel and is also referred to as rotation control data) is composed of six bit data (specifically, A, B, A-, B-, Vr1, Vr2). Combinations are configured to represent the exciting phase and exciting force. Specifically, bit 0 of A, B, A- and B- indicates "no excitation" for each phase, bit 1 indicates "excitation" for each phase, and the combination of Vr1 and Vr2 indicates Of the current (excitation force) for exciting the coil of FIG. Specifically, when Vr1 is 0 and Vr2 is 0, 0%, when Vr1 is 0, and when Vr2 is 1, 20%, when Vr1 is 1 and Vr2 is 0, 60%, and Vr1 is 1, Vr2. Is 100%.

  For example, in the excitation table “23H” having the table number “C0”, A is 1, B is 1, A− is 0, B− is 0, Vr1 is 1, and Vr2 is 0. It indicates that the excitation is performed at 60%. In the excitation table “21H” having the table number “C1”, A is 1, B is 0, A− is 0, B− is 0, Vr1 is 1, and Vr2 is 0. It indicates that the excitation is performed at 60%. Therefore, when switching the table number from “C0” → “C1” → “C2” → “C3” → “C4” → “C5” → “C6” → “C7”, the AB phase → A phase → It is possible to excite each phase by 60% in the order of AB-phase → B-phase → AB-phase → A-phase → AB phase → B phase and rotate the rotor 740 by an angle for one cycle. it can. As described above, in the present embodiment, the rotation of the reel is controlled by outputting the excitation table data (rotation control data) composed of 6 bits to the drive circuit 322 as a drive signal.

  In the excitation table “57H” having the table number “E0”, A is 1, B is 1, A− is 1, B− is 1, Vr1 is 0, and Vr2 is 1. It shows that all (all phases) of the B phase, the A-phase and the B-phase are excited at 20%. Similarly, in the excitation table “37H” having the table number “E1”, A is 1, B is 1, A− is 1, B− is 1, Vr1 is 1, and Vr2 is 0. Exciting the phase by 60%, the excitation table "77H" having the table number "E2" is such that A is 1, B is 1, A- is 1, B- is 1, Vr1 is 1, and Vr2 is 1. This indicates that 100% of all phases are excited.

  In this embodiment, as in the first and second embodiments, as shown in FIG. 37, the excitation force is 0% non-excitation, the excitation force is 20% weak excitation, and the excitation force is 60% medium excitation. , And the excitation force of 100% is also referred to as strong excitation.

<Rotation control table>
FIG. 36 is a table showing the contents of a rotation control table according to the third embodiment.
The contents of the rotation control table in the case where the reel control status is “brake control state (during brake control)” and “special brake control state (during special brake control)” are different from those of the first embodiment and the second embodiment. ing. In the third embodiment, the setting conditions of “during brake control” and “during special brake control” are the same as those in the first and second embodiments. "Special brake control is being performed" is set only for one frame, and "brake control is being performed" otherwise. Also, the first embodiment and the second embodiment are different from the first embodiment and the second embodiment in that when “special brake control” is set, the pull-in control is terminated in a phase four steps earlier than when “braking control” is set. Same as the form. Hereinafter, the configuration and operation different from those of the first embodiment and the second embodiment will be mainly described.

  In the third embodiment, unlike the first and second embodiments, the "brake control" and the "special brake control" are performed by all-phase excitation to stop the reels.

  Specifically, during the "braking control", as shown in FIG. 36, first, the rotation control data of the excitation table "77H" corresponding to the general-purpose offset counter value of 0 is held for "50", and The rotation control data of the excitation table “00H” corresponding to the offset counter value “1” is set to the rotation control data such as “1” holding time (in the present embodiment, the rotation is stopped by all-phase excitation). As described above, when the reel control status is "under brake control", the reels are stopped using the rotation control data of 100% excitation of all phases and then the rotation control data of 0% excitation (non-excitation) of all phases. I have to.

  FIG. 37 is a timing chart showing transition of stop control data after the second constant speed control when the normal pull-in control (brake control) is performed. FIG. 37 shows an example in which the number of remaining steps ST1 of the symbol when the stop operation is performed is 24, and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 24).

  In this case, the normal pull-in control is started from the time point t1 at which the stop operation is performed, and the time of 24 interrupt time (ST1) corresponding to the rest of the symbol at the time of the stop operation and the number of pull-in frames 1 are reduced. The table numbers “C0” to “C7” are sequentially and repeatedly set one by one for the corresponding 24 interrupt time (ST2), and the normal pull-in control is ended at time t2.

  Next, during "braking control" started from time point t2, the rotation control data of table number "E2" (rotation control data for exciting all phases by 100%) is interrupted for 50 hours, and then table number "A0" Is set for one interruption time, and the reels 110 to 112 are stopped.

  On the other hand, during "special brake control", as shown in FIG. 36, first, the rotation control data of the excitation table "57H" corresponding to the general-purpose offset counter value of 0 is held for "10", and then the general-purpose offset counter is set. The rotation control data of the excitation table “37H” corresponding to the value “1” is held for “10”, and the rotation control data of the excitation table “77H” corresponding to the general-purpose offset counter value “2” is held for “30”. Finally, the rotation control data of the excitation table "00H" corresponding to the general-purpose offset counter value of 3 is set to the rotation control data such that the holding time is "1" (in the present embodiment, the rotation is stopped by all-phase excitation). To make it work). As described above, when the reel control status is “under special brake control”, the rotation control data of all phases of 20% excitation, the rotation control data of all phases of 60% excitation, the rotation control data of all phases of 100% excitation, and finally, The reels are stopped using the rotation control data of all phase 0% excitation (non-excitation).

  FIG. 38 is a timing chart showing transition of the stop control data after the second constant speed control when the special pull-in control (special brake control) is performed. FIG. 38 shows an example in which the number of remaining steps ST1 of the symbol when the stop operation is performed is 24, and the number of drawn frames in the pull-in control is 1 (the number of steps ST2 = 20).

  In this case, the special pull-in control is started from the time point t1 at which the stop operation is performed, and the time of 24 interrupt time (ST1) corresponding to the rest of the symbol at the time of the stop operation and the number of pull-in frames 1 are reduced. The table numbers “C0” to “C7” are sequentially and repeatedly set by one interrupt time for the corresponding 20 interrupt times (ST2), and specially at time t3 (four interrupt times before time t2). The retraction control is ended.

  Next, during “special brake control” started at time t3, the rotation control data of table number “E0” (rotation control data for exciting all phases by 20%) is interrupted for 10 interruption times, and then the table number “E1” ) Of rotation control data (rotation control data for exciting all phases by 60%) for 10 interruption times, and then rotation control data for table number "E2" (rotation control data for exciting 100% of all phases) to 30 interruptions Time, and finally, the rotation control data (non-excitation rotation control data) of the table number “A0” is set for one interruption time, and the reels 110 to 112 are stopped.

  As described above, in the present embodiment, the brake control and the special brake control are performed using the all-phase excitation, and the reel is stopped. Also, when performing the special retraction control, the retraction control is terminated four steps before the normal retraction control is performed, and the process proceeds to the special brake control. Also, early and weak brake control is performed. As a result, even in the MB gaming state of the slot machine 100 using the reels 110 to 112 having 20 symbols applied to one reel, it is possible to stop not only the bitter but also the one-frame sliding. . That is, various stop modes can be realized even in the MB game state, and it is possible to prevent the appearance of a stop mode that may mislead the player.

  Note that, in the brake control of the present embodiment in which the reel is stopped using all-phase excitation, actually, the stop holding position is set several steps (for example, 6 steps corresponding to a 1/4 symbol) ahead of the retracted position. Therefore, the reference position of the index sensor is adjusted by using an inspection machine at the time of assembling the reel so that the stop holding position is several steps before. Specifically, when the actual stop holding position is the center of the symbol, the position at the time t2 when the brake control is started is a position several steps before the position corresponding to the center of the symbol.

<Modification of Third Embodiment>
FIG. 39 is a table showing the contents of a modification of the rotation control table of the third embodiment.

  39A to 39C, the rotation control data when the reel control status is "under special brake control" is different from the rotation control data of the third embodiment. That is, the details of the 50 interrupt time during which the all-phase excitation is performed during “special brake control” are changed.

  For example, in “under special brake control” shown in FIG. 39A, first, the rotation control data of 0% excitation of all phases is interrupted for 10 hours, and then the rotation control data of 60% excitation of all phases is interrupted for 5 times. Then, the reels are stopped by using the rotation control data of 100% excitation of all phases for 35 interruption times and finally the rotation control data of 0% excitation of all phases for 1 interruption time. As described above, special brake control may be performed such that the excitation force for all phases is gradually increased from non-excitation.

  Also, in the "special brake control" shown in FIG. 39 (b), the rotation control data of 100% excitation of all phases is interrupted for 20 times, then the rotation control data of 60% excitation of all phases is interrupted for 30 times, and the last. The reel is stopped using the rotation control data of 0% excitation of all phases for one interruption time. In this way, special brake control may be performed such that the exciting force for all phases is gradually reduced.

  39C, during the "special brake control", the rotation control data of 100% excitation of all phases is interrupted for 5 hours, the rotation control data of 0% excitation of all phases is interrupted for 15 times, and The reel is stopped by using the rotation control data of all phases 100% excitation for 30 interruption times and finally the rotation control data of all phases 0% excitation for 1 interruption time. As described above, the special brake control may be performed by providing a non-excitation period on the way. Thus, the non-excited rotation control data on the way is naturally included as the parameter value of the special brake control.

  In FIG. 39 (d), the rotation control data when the reel control status is “under brake control” and “under special brake control” are different from the rotation control data of the third embodiment. In other words, during the "braking control" shown in FIG. 39 (d), the rotation control data of 60% excitation of all phases is interrupted for 20 times, the rotation control data of 100% excitation of all phases is interrupted for 30 times, and finally. The reel is stopped by using the rotation control data of all phases 0% excitation for one interruption time, and in the "during special brake control" shown in FIG. Interruption time, then 10 interruption times for all-phase 20% excitation rotation control data, then 30 interruption times for all-phase 100% excitation rotation control data, and finally 10% for all-phase 0% excitation rotation control data The reels are stopped by using the loading time. In this way, in the first 20 interruption times, the excitation force of “under special brake control” is set to be weaker than “under brake control”, and the rotation amount of “under special brake control” is set to “under brake control”. The rotation amount may be larger than the rotation amount.

  As described above, according to the “under special brake control” of the present embodiment, since the brake control is performed earlier, the excitation force is relatively weakened as compared with the “under brake control”, and the rotation during “the special brake control” is performed. The amount is set to be larger than the rotation amount during “braking control”. Therefore, the content of the rotation control data is not limited to that shown in FIG. 39 as long as the rotation amount during “special brake control” is configured to be larger than the rotation amount during “brake control”. The “relatively weak excitation force” means that the excitation force during “special brake control” is set to “brake control” during the entire “period of brake control” and “under special brake control” (51 interruption time). This is a configuration in which the excitation force is made weaker than the excitation force during "control". The excitation force is based on the magnitude of the excitation current for all phases and the period during which the excitation current is supplied. For example, although not shown, first, the rotation control data of 100% excitation of all phases is used for 20 interruption times, and then the rotation control data of 0% excitation of all phases is used for 1 interruption time, and the reel is stopped. ), The reels are stopped by using the rotation control data of 60% excitation of all phases for 20 interruption times and then the rotation control data of 0% excitation of all phases for 1 interruption time. "Medium" may be set.

[Other Embodiments]
In the slot machines 100 of the first to third embodiments, the PM type stepping motor 700 is used, but the type of the stepping motor is not limited to this. For example, an HM type (Hybrid Type) stepping motor may be used. FIG. 35 is an external view of the rotor 810 and the stator 820 of the HM type stepping motor 800, and FIG. 36 is a diagram illustrating the excitation and rotation operations of the HM type stepping motor 800. In FIG. 36, the excitation phase is shaded.

  The stepping motor 800 is configured such that the magnetic pole teeth of the rotor 810 make one revolution of the reel in 63,480 steps. Since the stepping motor 800 is different from the stepping motor 700 that sequentially excites in the circumferential direction to rotate the rotor 740, the same exciting phase is arranged in the opposite axial direction. As shown, the same phase arranged in the opposite axial direction is sequentially excited by one to two phases, and the rotor 810 is rotated in one direction. Also in this case, the normal retraction control and the brake control as shown in FIGS. 11 to 12, 30 to 31, and 36 to 37, and FIGS. 11, 13, 30, 32, and Special pull-in control and special brake control as shown in FIGS. As described above, the present invention is applicable to any type of stepping motor regardless of the type of the stepping motor.

  In the first to third embodiments, the special brake control is applied when the number of pull-in frames in the MB gaming state is one, and the brake control is applied in other cases. The condition for separating the special brake control and the brake control is not limited to this. For example, regardless of the game state (whether or not the MB game state), the special brake control is applied when the number of drawn frames is one, and the number of drawn frames is other than one (0 to 3). In the case of (frame), the brake control may be applied. More specifically, the special brake control may be applied when the number of frames to be drawn is other than 0 (1 to 4), and the brake control may be applied when the number of frames to be drawn is 0.

  In the first to third embodiments, the special pull-in control and the special brake control are applied in the MB gaming state. However, the gaming state to which the special pull-in control and the special brake control are applied is limited to the MB gaming state. Instead, the present invention may be applied to the case where the number of drawn frames in the CB (challenge bonus) game state is one. That is, if at least one of the plurality of reels is in a game state in which at least one or more reels are stopped within a range of 75 msec from the time of operation of the stop button, a plurality of game May be a game state of ending.

  In the first to third embodiments, the special pull-in control and the special brake control are applied to the left reel 110, but the present invention is not limited to the left reel 110. The special pull-in control and the special brake control may be applied to the center reel 111 and the right reel 112, or two reels (for example, the left reel 110 and the middle reel 111) and all the reels (the left reel 110, the middle reel 111). 111, the right reel 112) may be applied with special pull-in control and special brake control.

  In the first embodiment and the second embodiment, when one magnetic pole R of the rotor 740 of the stepping motor 700 is stopped in the AB phase, that is, one magnetic pole R of the rotor 740 of the stepping motor 700 is always fixed to the same phase. Although the case of stopping after stopping has been described, the present invention is not limited to this. The phase to be stopped may be variable.

  For example, if a stepping motor is used in which the number of symbols applied to one reel is 20 and the number of pulses required to make one rotation of the reel is 504, the number of pulses allocated to one symbol cannot be equalized. It is necessary to set the number of pulses assigned to one symbol differently. For example, in the above example, the number of pulses assigned to one symbol may be 24 and 26, and two types of pulse numbers may be mixed. In this case, the phase for stopping one magnetic pole R of the rotor 740 is variable, and there are a plurality of stop patterns. Therefore, the phases to be stopped and the symbols to be stopped are managed in a table, and based on the table, One magnetic pole R of the rotor 740 will be stopped.

  Note that the stepping motor operates by sequentially switching the phase to be excited, and stops by not switching the phase to be excited. Therefore, in the type test, the phase signal of the stepping motor (the signal indicating the phase to be excited) is used. Based on the change, the rotation and stop of the reel are determined. More specifically, the phase signal of the stepping motor is output from the gaming table to the testing machine, and when the phase signal of the stepping motor changes on the testing machine (when the phase to be excited is switched). It can be determined that the reel is rotating (the stepping motor is operating), and when there is no change in the phase signal of the stepping motor (when there is no switching of the phase to be excited), It is possible to determine that the reel is stopped (the stepping motor is stopped).

  Further, in the first to third embodiments, the special retraction control is ended four steps before the normal retraction control, and the special brake control is executed earlier. The number is not limited to four steps. The optimum number of steps is calculated by considering various conditions such as the performance of the stepping motor and the size and weight of the reel.
