  2. Description of the Related Art Conventionally, as disclosed in Patent Document 1 and the like, stepping motors are often used for the driving means of the spinning cylinder of this type of gaming machine. A stepping motor has a large rotational torque and an excellent stopping performance, and is suitable for a gaming machine. For example, in a swivel-type game machine, the rotation of a stepping motor is started by depressing a rotation start operation lever, and then accelerated and shifted to a constant speed rotation state. In a game machine equipped with a spinning cylinder, if the time to shift to the constant speed rotation state after the activation of the spinning cylinder becomes slow, it will be delayed and hinder the promotion of continued games. In order to promote continuous games, it is important to make a transition to the constant speed rotation state immediately after the turning cylinder is started.

In general, the 1-2 phase excitation method is adopted for driving the stepping motor. Conventionally, for acceleration after startup, a drive current is supplied via a motor driver circuit based on the excitation output time data table shown in FIG. 24 (24B). The timer value (excitation time) in the excitation output time data table is sequentially output to the motor driver circuit by changing the number of interrupts while updating the index value by timer interrupt processing. Index numbers 0 and even correspond to 1-phase excitation drive, and odd numbers correspond to 2-phase excitation drive. In the acceleration process using indexes “0” to “18” of the excitation output time data table, a large timer value is set at the initial stage of acceleration, and the excitation time is gradually reduced.

In this embodiment, since the reel makes one turn by applying 504 excitation pulses, the angle change per excitation pulse is about 0.714 °.

  Excitation output data shown in (17B) is given to the motor drive circuit 115 as a drive signal (drive signal data) for the stepping motor. The output data table of the excitation sequence (17B) is stored in the main R0M 103, and excitation data is output by timer interrupt processing. An excitation phase for each stepping motor is determined by the excitation data, and an excitation pulse current is supplied to and supplied to the excitation phase.

  (25B) of FIG. 25 shows an example of drive control of the rotating speed of the rotating drum from the start to the stop of the stepping motor. From the start to the stop of the stepping motor, the rotation of the rotating cylinder rotation start lever 15 is operated to turn on the rotating cylinder rotation start switch 15a and the rotation of the stepping motor starts. The period t1, the constant speed rotation period t2 in which the constant speed rotation is maintained, and the depression of the rotation rotation stop buttons 16a to 16c are detected by the rotation rotation stop switches 16e to 16g, respectively, and related to the internal lottery result. A stop control period t3 for stopping the reel is included. The stop control period t3 includes a sliding movement time for adjusting the stop symbol position during the turning stop control.

  At the time of acceleration, excitation control is executed based on indexes 0 to 24 in (24A) of FIG. In the case of normal rotation, the value of the excitation output counter at the start of rotation is set to one of 1, 3, 5, and 7. For example, if the excitation output counter value at the start is 1, the state of 1-phase excitation is held until one timer interrupt is generated by index 0. In this embodiment, a timer interrupt is generated at a frequency of once every 1.5 ms. The next index 1 holds the two-phase excitation state until 31 timer interruptions occur. Hereinafter, in the acceleration period up to the index 24, the timer value in the two-phase excitation state is gradually decreased. When the normal rotation is performed, the excitation output counter is updated (+1) every time the number of occurrences of the timer interrupt reaches the set timer value (24A), so that the rotation speed gradually increases. When the value of the excitation output counter is other than 0 at the start of driving of the rotating drum, the excitation control at the time of acceleration similar to the above is performed by sequentially switching from the excitation state. During reverse rotation, excitation control is executed (see step S206 in FIG. 19) with the order of switching the excitation state reversed from that in normal rotation (see step S222 in FIG. 20).

  The main CPU 102 acquires the random number value generated by the random number generation circuit according to the processing state as an internal lottery random number value, and the internal lottery random number value is mainly used for lottery processing relating to a combination. The lottery processing is executed with reference to the above-mentioned lottery table every time the microcomputer 101 (main CPU 102) constituting the main control unit executes the unit spinning game (one game) by the rotation of the reels 8a to 8c.

As shown in FIG. 4, the main control board 100 includes a spinning cylinder rotation start switch 15 a for detecting the operation of the spinning cylinder rotation start lever 15 and the rotation rotation stop buttons 16 a to 16 c via a game relay board 150.

Thus, the player can be notified of the validity or invalidity of the lever operation or button operation by the light emission mode (for example, light emission color) of the LED. In addition to the lever, a push button can be used as the operating means of the rotating cylinder rotation start switch 15a.

  Stepping motors (251, 252, 253) for rotationally driving the reels 8a to 8c are connected to the main control board 100 via the rotating relay board 250, and the rotating cylinders arranged for the respective reels. The rotational position detection sensors 254, 255, and 256 are connected. As the stepping motor, for example, a pulse motor that rotates once by supplying a drive signal (excitation pulse signal) of 504 pulses (hereinafter also referred to as the number of steps) can be used. The rotational position of the stepping motors (251, 252, 253) can be controlled by applying an excitation pulse. Since 21 symbols are drawn on the reels 8a to 8c, it is necessary to apply excitation pulses of 24 (504 ÷ 21) steps to switch one frame from the symbol at a predetermined position to the next symbol. And The reels 8 a to 8 c are accommodated in a reel unit case and installed in the housing 1. The rotating rotation position detection sensors 254, 255, and 256 are reel index sensors each composed of a pair of light emitting elements and light receiving elements held at predetermined intervals. A light-shielding piece that can pass between the light-emitting element and the light-receiving element is provided at a predetermined reference position in the circumference of each reel. Each time each reel makes one revolution, the light shielding piece passes between the light emitting element and the light receiving element, so that the rotation position detection sensors 254 to 256 detect the reference position of the reel, and each time the reference position is detected, The detection signal is output to the main control board 100. Under the control of the main control board 100, it is possible to perform stop control at a predetermined position according to the lottery result and stop operation timing by receiving detection signals from these turn position detection sensors after the turn rotation. It has become.

  FIG. 6 shows the internal configuration of the spinning cylinder gaming machine A. The housing 1 is a box formed by a top plate 1a, side plates 1b and 1c, and a bottom plate 1d. Inside, a reel 8a to 8c, a medal hopper 305, a power supply device 400a, and the like are stored. The power supply device 400a is provided with a power switch (not shown) for power-on operation. A main board box 100 a that houses the main control board 100 is attached above the reel 8. Sub-boards such as the effect control board 200 are also arranged around the main board box 100a. The medal hopper 305 is a game medium payout device that is driven by the hopper motor 302 and discharges the medal stored in the tank toward a discharge passage (not shown) communicating with the medal payout port 21 through the medal discharge port 305b.

  A hopper motor 302, a medal payout sensor 303, and a full detection device 304 are connected to the main control board 100 via a payout relay board 301 and a payout control board 300. The payout control board 300 receives the payout control command from the main control board 100 via the payout relay board 301 and drives and controls the hopper motor 302. The medal payout sensor 303 is installed in the discharge passage, detects a game medal paid out from the medal hopper 305, and gives a detection signal to the main control board 100 via the payout relay board 301. The main control board 100 can transmit a payout control command for designating the payout number to the payout control board 300 when it is necessary to pay out a game medal by winning. The payout control board 300 receives the payout control command and controls the hopper motor 302 to perform payout processing of a specified number of game medals. The paid-out game medals are detected by the medal payout sensor 303, and the detection signal is input to the main control board 100 and used for the determination of payout completion.

  Next to the medal hopper 305, an auxiliary tank 306 for storing game medals overflowing from the overflow medal 305a overflowing from the medal hopper 305 is disposed. The auxiliary tank 306 is provided with a full detection device 304 that monitors the full state of the auxiliary tank 306, and the main control board 100 can receive a detection signal from the full detection device 304 via the dispensing relay board 301. ing.

FIG. 7 shows a schematic configuration of the effect control board 200.
The effect control board 200 includes a microcomputer having a sub CPU 206 and a microcomputer 205 having a sub ROM 207 and a sub RAM 208, and constitutes a sub control unit of the present invention. The microcomputer 205 is provided with an interrupt controller circuit 210 that applies an interrupt signal to the CTC 209 and the sub CPU 206. In addition, the effect control board 200 is provided with an I / O port circuit 211 and a counter circuit 212 for inputting / outputting signals to / from the effect I / F board 201.

The sub-RAM 208 is formed with a work area for storing data necessary for performing an effect such as an effect lottery random value used for effect-related lottery and game control (effect state) information on the effect control side. Yes. The sub RAM 208 stores an AT flag that is set in accordance with the transition to the AT mode.

Similarly to the counter circuit 114, the counter circuit 212 includes a random number generation circuit and a sampling circuit. The sub CPU 206 acquires the numerical value generated by the random number generation circuit as an effect random number value by sending an instruction to the sampling circuit according to the effect processing state (for example, the timing at which the effect control command is received). The random number for use is mainly used for a lottery for production.
The effect control board 200 has a function of receiving an effect control command from the main control board 100 and performing an effect process on light and sound, and outputs music and audio through the upper speaker 4 and the lower speakers 22a and 22b. An acoustic control signal is output to the acoustic generator 213. In addition, an LED board 204 on which an LED group constituting the decorative lamp unit 6 is mounted is attached to the inner side of the front door 5, and the effect control board 200 outputs an LED drive control signal to the LED board 204.

  The effect control board 200 transmits the liquid crystal control command associated with the effect control command to the liquid crystal control board 203 that performs image control of the liquid crystal display device 3 at a timing when image reproduction to be displayed on the liquid crystal display device 3 is necessary. The effect control board 200 is determined by lottery or uniquely from a plurality of types of effect contents prepared in advance based on the effect control command sent from the main control board 100, and a control signal for instructing execution of the determined contents Is transmitted to the liquid crystal control board 203, the sound generator 213, and the LED board 204 at a necessary timing, and the reproduction of the sound effect and the decoration lamp unit together with the effect image of the liquid crystal display device 3 corresponding to various effect contents. 6 LED lighting / flashing drive is realized. Therefore, under the control of the sub-control unit having the sub CPU 206 as a main component, various contents of effects are developed in time series according to the effect scenario based on the motif set for the revolving game of the revolving game machine A. You can excite the excitement of the spinning game.

  The sub ROM 207 of the effect control board 200 is executed under the sub control of the sub CPU 206, and determines the setting contents of the ART condition determination and the AT condition determination processing program for determining whether or not to grant the ART game by the ART grant lottery. AT setting content determination processing program, AT push order notification control program for notifying the push order of an AT role or a 6-choice replay winning role in RT gaming state, and adding the number of games to the game based on the lottery table An add-on determination program and an ART game period change processing program for changing the game period in the ART game state by adding the number of games added to the add-on when the add-on is determined are stored. In the above-mentioned ART grant determination processing program, an ART grant determination processing program for a small role selection opportunity in which an ART grant lottery is performed when a special small role (cherry, etc.) is elected in the normal gaming state, and an ART game grant is determined by the win And an ART grant determination process program during the bonus game by the ART grant lottery performed during the bonus game, and the number of games from the start of operation by turning on the power is counted. When the preset number of games is reached, the ART grant lottery is performed, An ART grant determination processing program for a set game count arrival opportunity to determine ART game grant by winning is included. The effect control board 200 constitutes an ART game execution means for performing the push order notification of the winning combination during an ART game by executing control of the AT push order notification control program.

  As shown in FIG. 4, a hall computer HC (a computer that comprehensively manages pachinko hall gaming machines) is connected to the main control board 100 via an external concentrated terminal board 401. Game information can be externally output to the hall computer HC. Further, the main control board 100 is connected to a rotating drum setting board 402 so that a detection signal from the rotating drum setting board 402 can be received. The rotation setting board 402 has a setting switch (not shown) for changing the “6-step setting” for setting the payout rate to one of six levels, and a reset switch (not shown) for canceling the game operation error. Etc., and the operation detection signal of each switch on the rotating drum setting board 402 is given to the main control board 100.

A processing procedure of main processing in the main control board 100 will be described with reference to the drawings. This processing procedure includes a series of flows necessary for one game. In addition, each process in this embodiment is shown with the step number, and the process in each step comprises the control means by a main control part or a sub-control part.
FIG. 8 shows main processing by the main control unit. This main process is executed under the control of the main CPU 102, and the main body of the process execution will be described as a main control board (main control unit) 100.

  When power is turned on to the revolving game machine A, a power-on signal is sent from the power board 400, and the main control board 100 receives the power-on signal and starts main processing. After the initial setting process (step S1) is performed when the power is turned on, the normal operation process (steps S2 to S15) is performed. First, a RAM initialization process (step S2) is performed. In the RAM initialization process, predetermined data used at the end of the previous game is cleared, and a work area necessary for the current game is secured.

  Next, a game state flag generation process is performed (step S3). In the game state flag generation process, a game state flag corresponding to the game state is set. For example, a general game flag is set for the normal game state. An internal winning flag is set when the internal lottery state where the bonus game is won in the internal lottery. In the bonus gaming state, a bonus gaming flag is set. Based on the game state flag set in the game state flag generation process, a main process corresponding to the game state is executed.

  A game medal insertion process (step S4) is performed. In the game medal insertion process, detection of game medals inserted into the main body of the gaming machine, management of credits, and automatic game medals when there is a request for re-games. In addition to performing insertion setting processing, etc., it is monitored whether or not a predetermined number of game medals required for starting the game have been inserted. When the prescribed number of game medals are inserted or the credit setting is confirmed, the game start condition is established, and the player performs the depressing operation of the rotation-rotation start lever 15 while maintaining this condition, that is, the rotation It waits for an operation detection signal from the rotation start switch 15a to be sent. By receiving the operation detection signal from the rotation rotation start switch 15a, the main control board 100 acquires the random number for internal lottery based on the counter value of the counter circuit 114 (step S5).

  An internal lottery process based on the acquired random number for internal lottery is performed (step S6). In the internal lottery process, an internal lottery based on the acquired random number for internal lottery and the role lottery table (general game lottery table or bonus game lottery table) corresponding to the current gaming state is performed, corresponding to the lottery result. Winning combination information (winning flag) is set and stored in the main RAM 104.

  FIG. 11 shows a lottery probability table (general game lottery table, RT lottery table and bonus game lottery table) of the general winning combination and bonus combination (big bonus game BB). The internal lottery is executed based on the combination lottery table of FIG. In the role lottery table, lottery probabilities are set so that the payout rate differs according to each of the six stages, and FIG. 11 shows an example of them. FIG. 11 shows the lottery probabilities calculated by the range of the lottery value assigned to each winning combination for the random number range (0 to 65535). The winning random number range is set so that a small role such as a cherry and a bonus combination can be drawn at the same time. In FIG. Indicates the probability value. In this embodiment, there are five types of RTs, RT1 to RT5, but the replay probability is substantially improved from RT3 to RT5, and the replay probability of the normal gaming state is about 1/100 in RT1 and RT2. It only improves. During RT3 to RT5 games, a lottery table during RT in which the replay lottery probability is set to 1 / 1.3, which is a higher probability than 1 / 7.3 during RT1 and RT2 games, is used.

  In the present embodiment, a big bonus game BB can be awarded as a special game. The prescribed number of big bonus game ends is 299. The big bonus game BB has two types of special symbol combinations (blue 7-blue 7-blue 7 or red 7-red 7-red 7) established by different winning flags, and the lottery probability combining them Is 1 /327.7 (however, the above-mentioned simultaneous lottery probability is excluded). In an internal winning state in which different big bonus winning flags are set, if any special symbol combination is stopped on any of the four active winning lines, it is possible to shift to a big bonus game. The bonus combination is a so-called zero-sheet combination, and no prize medal is paid out when winning. When winning a bell, watermelon, or cherry, nine, six, or one award medal is paid out. The cherry win is established only by stopping at the effective winning position of the left-handed cylinder.

  The bell role is a combination of the stop order of the reels 8a to 8c (left turning cylinder → middle turning cylinder → right turning cylinder, left turning cylinder → right turning cylinder → middle turning cylinder, middle turning cylinder → left turning cylinder → right turning cylinder, There are six types of general small roles: medium turning drum → right turning cylinder → left turning cylinder, right turning cylinder → middle turning cylinder → left turning cylinder, right turning cylinder → left turning cylinder → middle turning cylinder). In the normal gaming state, the combined lottery probability of the bell role is 1 / 8.2, but during the bonus game, it becomes a so-called JAC role that can be won regardless of the stop order and becomes a high of 1/1. Win with probability. When the Bell as JAC wins, 13 prize medals are paid out. The six types of bell roles distinguished by the pressing order are AT roles (pushing order bell roles) that can be won by stopping each spinning cylinder in accordance with the pressing order notification by the sub-control unit in the ART game. In the normal gaming state, each of the six selected bell roles is drawn based on a 1 / 32.8 lottery probability (combined lottery probability 6 / 32.8 of all bell roles), and any of the bell roles can be won. However, in the normal gaming state, since the push order is not notified, generally, when a so-called forward push stop operation is performed in which the stop is performed in the order of the left turn cylinder to the middle / right turn cylinder, the push order is incorrect. In many cases, no winning will occur. In the ART gaming state, the winning combination probability of the AT combination is improved by a factor of six when the push order is notified by navigation.

  The replay is a combination of replay symbols RP1 and RP2 (RP1 or 2-RP2-RP1 or 2), and there are six types of replays in which the combinations of the stop orders of the reels 8a to 8c are different as in the case of the bell. These replays with different combinations of stop orders are used in a selection game based on the push order for transition to RT2 at RT1. Note that the small role of cherry and watermelon is a chance role that triggers an ART grant lottery when winning.

  In the ART gaming state, a push order notification of the AT small role (AT role: 6 types of bell roles) is performed in the AT navigation control mode by the sub-control unit, and the winning AT role is surely stopped, The frequency of occurrence of replays increases and consumption of medals is small, and it becomes possible to gradually increase the number of medals held during ART games by acquiring small roles such as AT roles. In other words, in the push order notification ART, when the bell role is elected, the stop order of the left, middle and right cylinders for aligning the bell role with the active line is determined, and unless stopped according to the determined order, Spindle stop control is performed so as not to stop at the effective line. The same push order is determined even when the 6-option replay is won, and stop control is executed so that replay does not occur in stop operations other than the determined order.

  In the internal winning state of the bonus combination, the bonus winning flag is set as a carryover combination that can be carried over to the next and subsequent games. For this reason, at the time of winning the bonus combination, the winning period is maintained during the game period until the bonus combination is won. On the other hand, the winning combination other than the bonus combination is set as a carry-over impossible combination in which the winning flag cannot be carried over to the next game. Even during bonus carryover games, lotteries are drawn as usual, but whether or not to win a combination of symbols corresponding to the winning small combination at this time is determined based on a predetermined pull-in priority order. . In the present embodiment, stop control is performed so as to preferentially draw in the order of “(replay or small combination)> bonus combination”.

  Subsequently, a rotation effect lottery process (step S6) for determining the type (rotation effect pattern) of the special rotation effect according to the rotation mode of the reel (reel) by lottery, and a rotation rotation start setting for setting the rotation mode of the rotor Processing (step S7) is performed. Details of the spinning effect lottery process and the spinning rotation start setting process will be described later.

  After the setting process at the time of rotation rotation start (rotation rotation start setting process) is performed, the reel rotation start is performed and the reels 8a to 8c are shifted to the rotation state. After the reel rotation, when detection signals from the rotation rotation stop switches 16e, 16f, and 16g by the rotation operation of the rotation rotation rotation stop buttons 16a to 16c are output, the rotation cylinder to be stopped is stopped and controlled. Is performed (step S8). In the rotation stop processing, the number of sliding symbols is calculated from the stop control table based on the winning information and the stop operation procedure (stop operation timing) of the rotation, and the stop control of the rotation based on this is performed.

  The spinning stop process refers to a stop control position stored in the ROM 103 based on the stop operation position where each reel is stopped and the lottery result of the lottery process. This is done by stopping the rotation. The reel stop position is determined so as to be drawn and stopped within a predetermined number of symbols (4 frames stipulated in the game rules) from the position of the stop operation timing. When there are symbols corresponding to the lottery result within 4 frames from the position of the stop operation timing, the stop control is performed so that the winning combination symbols are aligned on the active line. In particular, in the re-game stop control process, when a re-game is won even in a normal game state or a bonus flag carry-over state, priority pull-in control is performed so that the re-game is always aligned on the active line. .

  In this embodiment, a push order navigation ART game using both a stop order notification game (push order navigation AT game) and an RT game is given as a privilege game, and in the spinning stop process during the push order navigation ART game, Stop control is executed with reference to the stopping sequence of the rotating drum. You may make it give the ART game which alert | reports the classification of AT symbol as a privilege game.

  When it is confirmed that all reels have stopped rotating, a winning determination process is performed (step S9). In the winning judgment process, it is checked whether or not the symbol combination corresponding to the winning combination has stopped on the effective winning line, that is, whether or not a winning has occurred. Based on the above, the number of game medals to be paid out is set. When a winning occurs, the medal payout number monitoring process is performed (step S10). In the medal payout number monitoring process, the medal hopper 305 is driven and controlled based on the payout information set in the winning determination process, and the game medal payout process and the credit addition process for the payout number are performed.

  Further, a re-game RT setting process for setting a re-game (replay) and setting a transition of the RT game state is performed (step S11). In the re-game RT setting process, it is determined whether the RT game establishment condition (when the symbol stop for RT establishment occurs) is established based on the winning information, and if the RT game establishment condition is established, RT Set transition to gaming state.

  In the re-game RT setting process (step S11), a re-game setting process for performing a re-game when the replay combination is established is performed. That is, it is determined whether or not the replay is stopped on the effective pay line, and when the replay is stopped, a setting process for giving a regame is performed, and the process proceeds to step S12.

  After the re-game RT setting process, it is determined whether or not a bonus game is in progress (step S12). If the bonus game is in progress, processing during bonus game operation is performed (step S14). In the bonus game operating process, a setting process required for continuing and ending the bonus game is performed. When the above processes and settings are completed, the process returns to the RAM initialization process (step S2).

  If it is not during the bonus game, it is determined whether or not the symbol combination of the bonus combination (special winning combination) has stopped on the effective winning line (step S13). If the bonus symbol has not stopped, the routine proceeds to RAM initialization processing (step S2). On the other hand, when the bonus combination is stopped, bonus game operation start processing is performed (steps S13 and S15). When the bonus game operation start process is completed, the process proceeds to a RAM initialization process in step S2.

  An outline of the operation at the time of the game in the rotary gaming machine A executed based on the main process will be described. First, when a player plays a game, after inserting a predetermined number of medals from the medal slot 10 or setting a BET from the credit amount, the player operates the rotation start start lever 15. This spinning start operation triggers a lottery performed inside the gaming machine. The game is started by the rotation start operation, and the reels 8a to 8c rotate, and after the normal rotation of the reels is confirmed, the operation of the rotation rotation stop buttons 16a to 16c becomes effective. Based on the timing of each stop operation, each reel is controlled to stop at a position corresponding to the internal lottery result. When any winning combination other than replay is won, when a symbol combination of the winning combination is established on the active line, a predetermined number of medals are paid out.

  FIG. 9 is a flowchart showing timer interrupt processing on the main control side activated by interruption every predetermined time based on the time count of the CTC 105. With reference to FIG. 9, a timer interrupt process executed every 1.5 ms (milliseconds) in the main control board (main control unit) will be described.

  When a timer interrupt occurs, the main control board 100 performs a saving process for saving the register to a predetermined stack area (step S20), and then performs a port input process (step S21). In the port input process, detection information from switches and sensors provided in the gaming machine is managed. Next, a rotation rotation control process is performed (step S22). In the rotation rotation control process, activation, rotation, and stop of the rotation are performed according to the rotation control flag. In the following description, it is assumed that the rotating cylinder rotation start lever 15 is operated and the rotating state is activated before the rotation of the rotating cylinder is started. Details of the rotation control process will be described later with reference to FIGS. After the rotating rotation control process, a periodic update process is performed (step S23).

(10A) of FIG. 10 shows a periodic update process.
In the periodic update process, 1 is added to the counter value of the interrupt counter provided in the main RAM 104 (step S100), and 1 is further subtracted from the values of the 1-byte timer and 2-byte timer provided in the microcomputer 101 of the main control unit 100 ( Steps S101 and S102). This interrupt counter is a counter for counting the number of interrupts that is updated by +1 for each interrupt. The counter value of the interrupt counter is updated in the order of “00” → “01” → “02” →... → “FE” → “FF” → “00” → “01” →. The 1-byte timer is a timer composed of 1 byte, such as a medal insertion sensor ON timer, a credit medal insertion interval timer, a stop button stop interval timer, a door open sensor (not shown) monitoring timer provided on the front door 5, etc. including. The 2-byte timer is a 2-byte timer, and includes a minimum game time (game interval time: for example, 4.1 seconds) timing wait timer, an extinguishing time timing timer, and the like.

  Next, a command output process is performed (step S24), and an effect control command that is set according to the processing state accompanying the progress of the game is transmitted to the effect control board 200. The main control board 100 outputs an effect control command for one byte for each interruption. Since one effect control command is 2 bytes long, one effect control command is transmitted by two successive timer interruptions.

  Next, display output processing (step S25) and abnormality monitoring processing (step S26) are performed. In the display output process, a control signal for performing light emission control and the like of LEDs and 7 segments provided in the gaming machine is output. In the abnormality monitoring process, for example, gaming machine abnormality (game operation error) such as an error at the time of medal payout by monitoring of the medal payout sensor 303 or a door opening error by monitoring of the door opening sensor is monitored.

  Further, external information signal output processing (step S27) is performed. In the external information signal output processing, a game medal insertion signal, a medal payout signal at the time of game medal payout, an error signal, and the like are output. These output signals are transmitted to the hall computer HC via the external concentration terminal board 401.

  After the processing of step S20 to step S27 is completed, it is determined whether or not the operation of the MAX bet button 11 is valid. When the MAXBET button valid flag is on and the operation is valid, the MAX bet button 11 is operated. If it does, a MAXBET operation command is set (steps S28 to S30). The MAXBET button valid flag is normally turned on after the turning rotation start lever 15 is turned on and turned off after all reels are stopped. Therefore, when the MAX bet button 11 is operated during the game, a MAXBET operation command is transmitted to the effect control board 200, and the effect control board 200 that receives the command can execute a predetermined game effect / notification. . After setting the MAXBET operation command, the contents of the register are restored (step S31), and the timer interrupt process is terminated. Even when the MAX bet button 11 is not operated or when the MAXBET button valid flag is OFF, the contents of the register are restored (step S31), and the timer interrupt process is terminated.

FIG. 12 shows the details of the above-mentioned spinning drum lottery process (step S6).
Based on the result of the internal lottery, whether or not to execute the spinning effect (special rotation effect) is determined according to the winning combination, and the spinning effect pattern (a type of reel rotation effect pattern, hereinafter referred to as a rotation effect pattern). Is determined (step S40).

FIG. 16 shows a rotation effect pattern lottery table (16A), a reel effect setting table (16B), and a reel activation timer setting table (16C). These tables are stored in the main ROM 103. The rotation effect pattern is composed of seven types (PTN1 to 7). Each rotation effect pattern is drawn in a row when BB winning, simultaneous winning with BB (BB + Bell, BB + Watermelon, BB + Cherry), or a small combination of Bell, Watermelon and Cherry are won. The rotation effect pattern PTN1 includes only so-called freeze effect contents that cause a game progress stop state (freeze effect) in which the progress of the spinning game is stopped for 5 seconds. The rotation effect pattern PTN2 includes a composite reverse rotation effect content (composite reverse rotation effect mode) in which a spinning cylinder reverse rotation effect that reversely rotates the reel for 10 seconds appears in addition to a freeze for 5 seconds. The rotation effect pattern PTN3 includes a composite reverse rotation effect content in which a spinning cylinder reverse rotation effect that reversely rotates the reel for 20 seconds appears in addition to the freeze for 5 seconds. The rotation effect pattern PTN4 is made up of the contents of a single freeze effect for 30 seconds.
In the case of the rotation effect pattern PTN1, a lottery is performed at the time of winning excluding the BB winning among the above-mentioned seven kinds of opportunities, for example, a lottery with a probability of 1 / 32.0 at the time of cherry winning. In the case of the rotation effect pattern PTN2, a lottery is performed when one of the seven types is won, and, for example, a lottery probability is 1 / 18.0 when the bell is won. In the case of the rotation effect pattern PTN3, lottery is performed at the time of winning five types except the simultaneous winning (BB + Bell) and the bell role winning. For example, at the cherry winning, the lottery is drawn with a lottery probability 1 / 16.0. In the case of the rotation effect pattern PTN4, the lottery is performed only when BB is won, and the lottery is performed with the lottery probability 1 / 5.8.

  The rotation effect patterns PTN5 to PTN5 have delayed start effect contents for starting any one of the reels 8a to 8c with a delay from the normal rotation at the time of starting the reel. Reel 8a (left-hand drum) and reel 8b (medium-turn drum), respectively. ), Corresponding to the delayed start of the reel 8c (right cylinder). In the case of the rotation effect pattern PTN5, lottery is performed only at the time of simultaneous winning (BB + cherry) and cherry winning, for example, when the cherry is winning, the lottery is drawn with a probability of 1 / 18.0. In the case of the rotation effect pattern PTN6, a lottery is performed only at the time of simultaneous winning (BB + Bell) and a bell winning, for example, a lottery with a lottery probability of 1 / 18.0 when winning a bell. In the case of the rotation effect pattern PTN7, lottery is performed only at the time of simultaneous winning (BB + watermelon) and watermelon winning. For example, at the time of watermelon winning, the lottery is drawn with a lottery probability of 1 / 18.0. The rotation effect pattern is not limited to the reverse rotation, and a rotation mode such as a slow rotation and a frame feed rotation that are normally rotated at a lower speed than the normal rotation can be used.

  When either the spinning effect execution or the spinning effect pattern is determined according to the winning combination (step S41), the spinning effect pattern data is stored and set in the main RAM 104 (step S42). By setting the spinning effect pattern, the game lock index (reel effect type PTN1 to PTN7) corresponding to the lottery result of the rotation effect pattern in (16A) of FIG. 16 is set and the game lock command is set in the main RAM 104. (Step S42). Next, it is determined whether or not the freeze effect has been won. When the freeze effect is won, the freeze time (waiting time) corresponding to the game lock index is set in a predetermined register (BC register) with reference to the setting table (16B). Then, the process proceeds to the designated number interrupt waiting process (steps S43 to S45). The value set as the waiting time is, for example, “3334” in the case of a 5-second freeze. When the freeze effect is not won, the waiting time is not set, and the process proceeds to a designated number interruption waiting process (steps S43 and S45).

(10B) of FIG. 10 shows a designated number interrupt waiting process (step S45).
First, the counter value of the interrupt counter shown in the periodic update process (10A) is acquired (step S110). The acquired value is compared with the counter value of the interrupt counter (step S111). This comparison continues until the two do not match, and one interrupt process is completed. When the comparison results do not match, the comparison ends (step S112), and the process proceeds to step S113. In the BC register of the main CPU 102, a designated number of interrupt wait times is preset. In step S113, 1 is subtracted from the BC register. The above steps S110 to S113 are repeated a specified number of times. When the value of the BC register becomes 0, the specified number interrupt waiting process is terminated (step S114). If “3334” is set in the BC register as the 5-second freeze standby time, the processing of steps S110 to S114 is looped 3334 times, and the time required for this is about 5 seconds (1.5 ms × 3334). = 5001 ms).

FIG. 13 shows the rotation rotation start setting process (step S7).
In the rotation rotation start setting process, a weight process is first performed. In the wait process, a predetermined time (for example, 4.1 seconds) is counted by a weight timer from the start of the reel rotation in the previous spinning game, and the current spinning game is performed until the predetermined time (wait time) elapses. This is a process for waiting without starting the rotation of the reel.

  In the wait process, the timer value of the wait timer is acquired (step S50), and the time is counted until the wait timer reaches 0, that is, the wait time is consumed (steps S51 and S52). When the wait time is consumed (step S52), the wait time (4.1 seconds) until the next game start is newly set in the wait timer (step S53), and the process proceeds to the rotation starting process (step S54). This wait timer is subtracted by the above-described regular update process. In the rotation activation process, the rotation activation condition according to the rotation activation pattern and the rotation effect pattern at the time of normal rotation is set, and details thereof will be described later.

  When the rotation starting process is finished, a rotation state flag indicating that all reels are rotating is turned on (step S55). Further, a rotation start command is set (step S56), and the rotation rotation start setting process is terminated.

FIG. 14 shows the rotation starting process (step S54).
First, the game lock index (see step S42) set at the time of setting the spinning effect pattern is acquired (step S60), and the startup data corresponding to the acquired game lock index is stored in the startup data area provided in the main RAM 104. It is set (step S61).

  The start-up data according to the acquired game lock index is set based on the reel effect-specific setting table and the reel start timer setting table shown in (16B) and (16C) of FIG. Rotation effect patterns PTN1 to PTN4 are independent freeze effect contents or composite reverse rotation effect contents, and the start-up data of reverse rotation presence / absence, reverse rotation time, and rotation order of the third cylinder are set according to the contents of each effect. . The rotation effect patterns PTN5 to PTN5 are the contents of the delayed start effect of the spinning cylinder, and start time data of the start delay time (300 ms) for the delay target cylinder is set according to the contents of each effect.

  In the case of the rotation effect patterns PTN1 to PTN4, the rotation order at the time of starting the rotating cylinder causes all reels to be simultaneously started to rotate so that no starting delay occurs. The rotation order “123” shown in (16B) represents the order in which the reels are activated. Since each of the rotation effect patterns PTN5 to PTN5 is the delayed start effect content, the rotation order is set. In the case of the rotation effect pattern PTN5, as shown in the rotation order “231” of (16B), the rotation is started in the order of right, left, and middle rotation. In the case of the rotation effect pattern PTN6, as shown in the rotation order “132” of (16B), the rotation is started in the order of left, right, and middle rotation. In the case of the rotation effect pattern PTN7, as shown in the rotation order “123” of (16B), the rotation is started in the order of left, middle, and right spinning.

  During normal rotation, the three cylinders are simultaneously activated in the normal rotation (forward rotation) direction without causing a start delay. Also during the reverse rotation effect, the three cylinders are activated in the reverse rotation direction opposite to the normal rotation almost simultaneously without causing a start delay. At the time of delayed start production that delays the start of the left, middle, and right cylinders, the first two cylinders are activated almost simultaneously in the normal rotation direction, and the remaining delays after the rotation delay time (300 ms) has elapsed since the activation. The target cylinder is activated in the normal direction of rotation. At the time of reverse rotation effect, after the reverse rotation effect of the rotating drum is finished, the first rotating drum is activated after the rotation delay time (38 seconds) has elapsed, and the next rotation after the rotation delay time (500 ms) has elapsed since the activation. The cylinder is activated, and after the activation, the last cylinder is activated after the rotation delay time (500 ms) has elapsed. As described above, according to the game state, that is, based on the game lock index, the spinning delay time shown in (16C) is set for the reel start timer (step S62).

After setting the start time data and the rotation delay time, after performing the first rotation start setting (steps S63 to S68) corresponding to the start time data, when the start time data is reverse rotation, the reverse rotation to the normal rotation The second rotation activation setting (steps S70 to S76) is performed.
In the first rotation activation setting, data setting (steps S63, S65, and S67) and activation setting processing (steps S64, S66, and S68) for each rotation cylinder are performed for the three rotation cylinders. Is called. In the second rotation activation setting, the rotation delay time data setting (steps S71, S73, S75) and the activation setting process (steps S72, S74, S76) are performed for each of the three rotation cylinders. Is called. The activation setting process (steps S64, S66, S68) and the activation setting process (steps S72, S74, S76) are executed by a common activation setting process to reduce the capacity burden on the main CPU 102.

  In the first rotation activation setting, a rotation delay time “0” is set in the BC register for one of the two rotation cylinders other than the delay target (step S63), and activation setting processing for the rotation cylinder is performed. (Step S64) is performed. After setting the rotation delay time “0” and starting setting processing for the next rotation cylinder (steps S65 and S66), the rotation delay time for the last rotation cylinder is set (step S67). . When the start delay effect is included, 300 ms is set as the rotation delay time (the value set in the BC register is 200, and 300 (1.5 ms × 200) ms is set). At the time of reverse rotation effect, a rotation delay time “0” is set for each rotation. The rotation delay time set in step S67 is consumed by the designated number interruption waiting process (step S80 in FIG. 15), and appears as a start delay rotation effect in which the start of reel rotation is delayed from the normal time.

FIG. 15 shows the activation setting process (steps S64, S66, S68, S72, S74, S76).
In the startup setting process, first, the designated number interrupt waiting process (step S80) shown in (10B) of FIG. 10 is performed, and after the delay time set in the BC register is consumed, the process shifts to the interrupt disabled state ( Step S81). Next, the reel of the target cylinder corresponding to the rotation start order is specified (step S82), and a control flag corresponding to the specified target reel is set (step S83). At this time, if a reverse rotation effect is included, the reverse rotation flag is set. After step S83, the interrupt disabled state is released, the interrupt is permitted, and the process ends (step S84).

  Here, various swivel control flags used in the main control unit are shown in FIG. (17A) of FIG. 17 is a data table of each cylinder control flag. In addition to the control flag and the reverse rotation flag, the rotation control flag includes a rotation sensor ON flag, a stop command flag, a stop signal detection flag, a rotation start flag, a rotation start flag, and a rotation stop flag. It is.

FIG. 18 schematically shows the generation timing of each cylinder control flag. FIG. 18 shows the turn-on state of each spinning cylinder control flag in the period rising from the lower line, and shows an example of rotation timing including a reverse rotation effect.
The control flag is a flag indicating that the rotation control of the rotation (normal rotation) of the rotating drum is being performed. As shown in (18A) of FIG. 18, the control flag is turned on at time T8 when the rotating cylinder rotates from the first start setting (steps S64, S66, S68) T1 and completes the stop operation. Corresponds to the period up to.
The reverse rotation flag is a flag indicating that the reverse rotation control is being performed in the reverse rotation effect of the rotating drum. As shown in (18B), the reverse rotation flag is turned on at a time T2 at which the rotating cylinder reversely rotates for a predetermined period from the first activation setting time T1 and shifts to normal rotation (steps S72, S74, S76). Corresponds to the period up to.

  The rotation sensor ON flag is a flag indicating that the reference position of each rotation is detected by the rotation position detection sensors 254 to 256. (18C) As shown in (18C), the turn-on sensor ON flag is in the on-rotation state detection sensor after time T3 when the reel rotation reaches the rotation state at the steady speed (steady rotation state) after the rotation is started. This corresponds to the period from the time T4 when the detection signal of the reference position of the reels 254 to 256 is received to the time T8 at which the full rotation of the reel is stopped.

The stop command flag is a flag indicating that a stop command has been generated as a result of a stop operation performed by the spinning cylinder rotation stop buttons 16a to 16c. As shown in (18D), the on-state of the stop command flag corresponds to a period from time T6 when the number of sliding pieces becomes 0 by stop control to time T8 of complete rotation stop.
The stop signal detection flag is a flag indicating that a stop signal generated by a stop operation by the spinning cylinder rotation stop buttons 16a to 16c is detected. As shown in (18E), the on state of the stop signal detection flag corresponds to the period from the time T5 when the stop signal is detected in the steady rotation state of the rotating cylinder to detect the stop signal until the rotating cylinder complete stop time T8. .

The rotating cylinder activated flag is a flag indicating that the rotation of the rotating cylinder has reached a steady rotation state. As shown in (18F), the turning-on activated flag on state corresponds to the period from the time T3 when the steady rotation state is reached to the time when the turning complete stop T8.
The spinning cylinder start flag is a flag indicating that the engine is starting up from the start in the normal rotation state to the steady rotation state. As shown in (18G), the turn-on activation flag ON state corresponds to the period from the reverse rotation end time T2 to the steady rotation state arrival time T3. When reverse rotation is not performed, it is turned on at T1 to T3.
The spinning cylinder stop flag is a flag that indicates a transition to the complete rotation control of the spinning cylinder after the number of sliding pieces becomes zero. As shown in (18H), the turning-turn-stop flag on state corresponds to the period from the time T7 when the reel moves to a position where the reel can stop after the sliding piece becomes 0 to the time when the reel complete stop T8. To do.

  The data setting of the rotation delay time (steps S63, S65, S67) and the start setting process (steps S64, S66, S68) are executed for each rotation, and for example, the left reel start delay effect is determined by lottery. When it is set, the data setting and activation setting processing of the rotation delay time is performed in the order of the middle, right, and left rotation, and the delayed rotation of the left rotation is executed.

  When the rotation activation setting at the normal rotation is finished (steps S63 to S68), it is determined whether or not the reverse rotation effect is determined by lottery. When the reverse rotation effect has not been determined, the rotation starting process is performed only during normal rotation and the process ends (step S69).

  When the reverse rotation effect is determined, the reverse rotation data is cleared after the reverse rotation time set in step S61 has elapsed (step S70). In the case of reverse rotation in the previous step S61, since the rotation order is set to 123, the order of switching from reverse rotation to forward rotation is in the order of left middle right, but the rotation order data should be set at this timing. The switching order can be changed as appropriate. As shown in (16C) above, a value corresponding to the reverse rotation time of 38 seconds is set in the BC register (step S71), and the activation setting process (step S72) for the rotating drum is performed. After waiting for the reverse rotation time of 38 seconds to elapse in S80, the data cleared in step S70 is set in the reverse rotation flag (memory area) corresponding to the first spinning cylinder (step S83). At this timing, the first cylinder shifts to the normal rotation. A rotation delay time (500 ms) after activation of the first rotation is set for the next rotation (step S73), and activation setting processing (step S74) for the rotation is performed. Further, a rotation delay time (500 ms) after activation of the second rotation cylinder is set for the last rotation cylinder (step S75), and activation setting processing (step S76) for the rotation cylinder is performed.

  With the above rotation activation process, the rotation activation condition necessary for normal rotation activation to activate the rotation stepping motor and the rotation rotation condition corresponding to the rotation effect pattern at the time of the reverse rotation effect are set. When there is no reverse rotation effect, the rotation start process of steps S60 to S69 for forward rotation drive is executed without turning on the reverse rotation flag in the first rotation start setting process. When there is a reverse rotation effect, the reverse rotation flag is turned on in the first rotation activation setting process, the rotation activation process of steps S60 to S69 for the reverse rotation drive is executed, and the normal rotation drive after the reverse rotation is performed. The second rotation start setting process in steps S70 to S76 is executed. Therefore, when performing the setting for starting to rotate the rotating cylinder forward only (normal rotation) and forward rotating through the reverse rotation effect, the startup setting means (steps S80 to S85) in FIG. The reverse rotation effect control of the rotating drum can be smoothly executed without giving a burden of program capacity to the main control unit.

In this embodiment, since the rotation effect pattern includes a rotation start delay in addition to the reverse rotation effect, in this embodiment, in the case of only forward rotation and when performing the reverse rotation effect, each rotation Although the rotation delay time is set and the activation setting process is performed, when the rotation delay effect is not performed, steps S63, S65, S67, S71, S73, S75, and S80 are not necessary, so only forward rotation is performed. In the case of the above and in the case of performing the reverse rotation effect, the common start-up setting for setting the control flag and the reverse rotation flag corresponding to all the cylinders may be performed once at the time of normal rotation start and reverse rotation start. The program processing can be simplified.
Therefore, under the restrictions of the game rules in which the lottery process and the spinning cylinder rotation process are performed in the main control unit, it is related to the game information based on the lottery result of the main control unit by the effect display device such as a liquid crystal display device and various lamps. The related control notification control can be executed in the sub-control unit, but the special rotation effect of the rotating cylinder such as reverse rotation needs to be under the control of the main control unit. The rotation effect pattern is selected by lottery, and according to the content of the determination, the start time setting means (steps S80 to S85) is shared, and the start time setting is performed for each rotating drum, and the main control is performed. It is possible to smoothly execute the rotation effect control of the rotating cylinder without giving a burden of program capacity to the section, and to further improve the interest of the rotating game.

  Further, in this embodiment, in addition to the reverse rotation effect, the rotation effect pattern includes the rotation start delay, the reel rotation order, and the freeze effect. In particular, the rotation start delay time setting and start setting processing are performed. Since each rotation is performed, even if a plurality of types of rotation effect patterns are used, the rotation effect control of the rotation can be smoothly executed without giving a burden of program capacity to the main control unit.

The spinning cylinder rotation control process (step S22) executed in the timer interrupt process (FIG. 9) will be described in detail below.
19 to 23 show the rotating cylinder rotation control process (step S22).
In the rotation rotation control process, a process in the rotation control process in which the control flag is on is performed. When the reverse rotation flag is on, the reverse rotation control processing from step S203 (see FIG. 19) is performed. When the in-rotating flag is on, the in-rotating stop control process in step S208 (see FIG. 19) and subsequent steps is performed. When the rotation activation flag is on, the rotation rotation acceleration control process after step S215 (see FIG. 20) is performed. At the start of rotation of the rotating cylinder, the rotation rotation start control process in step S227 (see FIG. 21) and subsequent steps is performed. During the steady rotation state, the rotating cylinder steady rotation control process in step S232 (see FIG. 22) and subsequent steps is performed. After the stop signal detection flag is turned on, the stop slip control process until the stop command flag is turned on is performed after step S240 (see FIG. 23). When the stop command flag is turned on, step S247 (see FIG. 23) is performed. After that, the process proceeds to the control process while the rotating cylinder is stopped. In FIG. 19 to FIG. 23, the flag on / off setting is expressed as “1” and “0”, respectively.

  First, the first spinning cylinder control flag is checked to confirm the flag contents (step S200). When the control flag is off (step S201), the process proceeds to step S225 to determine whether or not the processing for three reels is finished. If the processing for three reels is not finished, the process returns to step S200, and the next Check reel control flags. When the rotation control of all three reels has been completed, the rotating cylinder rotation control process ends. When the control flag is on based on the detection of the rotation of the rotating cylinder rotation start switch 15a, it is determined whether or not the reverse rotation flag is on (steps S201 and S202). When the reverse rotation flag is on, the motor output timer is decremented by 1 to activate reverse rotation (step S203). The main RAM 104 is provided with a counter memory area for an excitation output counter for specifying an excitation pulse for performing motor drive current supply control by the motor drive circuit 115. Hereinafter, the output data of the excitation output counter is referred to as excitation output data. The motor output timer is a timer provided in the main control unit for updating the excitation output counter. When the rotation of the stepping motor (left cylinder drive motor 251, middle cylinder drive motor 252, right cylinder drive motor 253) is accelerated, the excitation output counter is updated by the motor output timer when the count value of the excitation output counter becomes zero. In addition, when the stepping motor is stopped, the time during which all phases are turned on is managed by the motor output timer.

  Next, it is determined whether or not the value of the motor output timer is a negative value, that is, whether or not the timer of the motor output timer is being measured (step S204). If the value of the motor output timer is a negative value, the motor output timer Is set to "5" (step S205), and the excitation output counter is decremented by 1 (step S206). As described above, the motor output timer is decremented by 1 for each timer interrupt, and when the negative value is obtained, the excitation output counter is decremented by 1. Therefore, when “5” is set in step S205, six timer interrupts are generated. The excitation output counter is updated every time (1.5 ms × 6). In the present embodiment, by subtracting 1 in S206, a reverse rotation drive in which the excitation output counter rotates in the direction opposite to the normal rotation can appear. As described above, the reel effect is not limited to the reverse rotation, and may be forward rotation such as slow rotation and frame feed rotation, and the rotation direction and rotation speed can be arbitrarily set. When the value of the motor output timer is positive or 0, the process proceeds to step S223 described later.

  When the reverse rotation flag and the rotating cylinder stop flag are both off, it is determined whether or not the rotation start flag is on (step S214). When the rotation activation flag is off, the process proceeds to the turning-on activation flag on / off determination process (step S226). When the control flag is on and the rotation activation flag and the rotation activated flag are off, the state immediately after the rotation rotation start lever 15 is operated, and the rotation rotation start control process is performed.

In the rotation rotation start control process, excitation control start correction is performed (step S227). Excitation control start correction is required for the following reasons.
When the rotary rotation stop switches 16e to 16 are pressed, even if brake braking (all phase excitation for exciting all four phases) is applied to the reels 8a to 8c, the reels do not stop immediately. That is, until the reel actually stops, it slides by one or two step angles and stops. When slipping and stopping, it is necessary to perform a new acceleration process while absorbing the deviation of this angle, and it is preferable that the electromagnetic attractive force (torque) in the initial excitation is as small as possible. When the initial excitation is two-phase, rattling is noticeable because the torque is strong. If the phase is weak, the shift can be absorbed slowly so that the backlash is not noticeable. For this reason, the start correction is performed by clearing the excitation output counter bit 0. By clearing the excitation output counter bit 0, the excitation output counter becomes one of “0”, “2”, “4”, “6”, and then the excitation output counter is incremented by 1 in step S222 described later. Is one of “1”, “3”, “5”, and “7”. Accordingly, as is apparent from the excitation output table of (17B) in FIG. 17, excitation control can be forcibly started from one-phase excitation.

  After the excitation control start correction is performed, the rotation start flag is turned on to start the rotation (step S228). By turning on the spinning cylinder start flag, the spinning cylinder rotation acceleration control process is performed in the next interruption process. At this time, the rotation sensor ON flag is turned off in order to detect steady rotation. Next, since the rotational movement of one symbol requires the application of excitation pulses of 24 steps, the symbol step number counter is initialized, that is, the initial value (24) of the excitation pulse in one symbol unit is set ( Step S229). After setting the initial value of the number of symbol steps, initialization at the time of reel activation is performed (step S230). In this initialization, an error timer (timer count memory area provided in the main RAM 104) for monitoring the rotating rotation abnormality of the timer is cleared, and a symbol counter for counting the total number of 21 reel symbols is cleared. Further, the output timer table index value in the output timer index memory area is set to 0, and further, 1 is set to the motor output timer value. The number of symbol steps is decremented by 1 for each excitation output of the motor, and when it becomes 0, it is set and updated to 24. The symbol counter is incremented by 1 every time the number of symbol steps becomes 0, and when 21 is reached, 0 is set and updated. The output timer index memory area is provided in the main RAM 104, and the index value in the output timer index memory area is updated each time a timer value corresponding to the index is acquired from the excitation output time data table (24A). The symbol counter and motor output timer described above are also provided in the main RAM 104. After step S230, the process proceeds to step S215 due to turning-on activation flag ON (step S228).

  When the rotation activation flag is turned on (step S214), the rotation rotation acceleration control process in step S215 and subsequent steps is performed. First, 1 is subtracted from the value of the motor output timer to determine whether or not the value of the motor output timer is 0 (steps S215 and S216). Since 1 is set in the motor output timer in the initialization setting at the start of rotation of the rotating cylinder, the motor output timer becomes 0 in the first acceleration control. When the value of the motor output timer is 0, motor excitation output update processing (step S217) is performed. In the motor excitation output update process, the timer value corresponding to the output timer table index value stored in the main RAM 104 is acquired with reference to the excitation output time data table of (24A). For example, if it is immediately after activation, as shown in (24A), since the index value is 0, “1” is acquired as the timer value. The acquired timer value is set in the motor output timer, and 1 is added to the index value stored in the output timer index memory area (steps S218 and S219).

  After adding the index value, it is determined whether or not the acceleration period has ended. The end of the acceleration period can be determined based on whether the index value exceeds 25 or whether the timer value set in the motor output timer is 150. When the acceleration period ends, the reel rotation acceleration process ends (step S220). An index 25 is set at the end of the acceleration period, and the number of interruptions for 150 times used for counting the all-phase hold time for holding (holding) the all-phase ON state when the rotation is stopped can be set. In the conventional case shown in (24B), the all-phase hold time can be set by the index 19 in (24B).

  The above-described rotation rotation acceleration control process is executed based on the excitation output time data table (24A). In the present embodiment, as shown in (24A), when performing the rotational drive control of the stepping motor by the 1-2 phase excitation method, the excitation time of the two-phase excitation is longer than the one-phase excitation during the acceleration period. The two-phase excitation time is gradually shortened step by step. Moreover, the one-phase excitation during the acceleration period is set to the minimum unit time (time required for one interrupt process). That is, the timer values are assigned to indexes 1, 31, 1, 10,.

  In the rotation rotation acceleration control process after step S215, the timer value corresponding to the one-phase excitation period with a weak torque is set to “1” to shorten the time as much as possible, and the two-phase excitation period with a strong torque is lengthened. Since it is set and gradually shortened step by step, a smooth spinning game can be promoted by quickly shifting to a constant speed rotation state in the acceleration process after starting the spinning cylinder. In particular, from the viewpoint of long-term operation, the load on the stepping motor can be reduced, which contributes to extending the life of the revolving motor. In the present embodiment, the acceleration period ends in 24 steps. However, the acceleration period may be increased or decreased from 24 steps.

  At the end of the reel rotation acceleration process, the turn-starting flag is turned off and the turning-starting flag is turned on (step S221). As a result, in the next interrupt process, the rotating cylinder steady rotation control process is performed.

  When the cumulative index value has not reached 24, the reel rotation acceleration process is continued (step S220). While the reel rotation acceleration process is continuing and when it is finished, 1 is added to the excitation output counter (step S222). Next, the excitation data corresponding to the counter value of the excitation output counter is acquired with reference to the excitation output table of (17B) of FIG. 17 (step S223). The acquired excitation data is stored in the output buffer corresponding to the reel (step S224). The excitation data stored in the output buffer is output to the motor drive circuit 115 together with the output of the LED or the like, for example, in a later display output process (step S25). The above excitation pulse output to the stepping motor is executed for all three reels (step S225). On the other hand, when the value of the motor output timer is not 0 in step S216, the index value, excitation output counter, and excitation output data are not updated, so that the previous excitation data is kept in the motor drive circuit until the motor output timer value becomes 0. The output continues to 115.

  During the steady rotation state, the normal rotation state is monitored and maintained until the stop signal detection flag based on the stop operation is turned on. During the constant speed rotation period t2 (during steady rotation), one phase and two phases are alternately excited based on the excitation output table of (17B) in FIG. Is maintained. When the steady rotation state is entered and the stop signal detection flag is not turned on (step S231), the reel rotation is monitored for normality / abnormality according to the counter value of the excitation output counter. When bit 0 of the counter value of the excitation output counter is 0 (step S232), it is determined that the two-phase excitation state is present, and the error timer is incremented by 1 (step S233). This error timer is a timer that measures the time of one pulse for each pulse of drive signal (excitation pulse signal) applied to the stepping motor. Since the stepping motor makes one rotation by giving a drive signal (excitation pulse signal) of 504 pulses, if the stepping motor one rotation time is monitored by the timer monitoring of the 504 pulse time by the error timer, the timer capacity is stored for 504 pulses. Requires capacity. In the present embodiment, in order to reduce the capacity burden on the main controller, the time required only for the two-phase excitation state is counted, and the capacity required for the error timer is reduced. Specifically, since the reel one round time corresponds to 504 pulse time, the time may be increased by 252 pulse time, but the error timer has some margin (256 (= 252 + 4) pulse time (> reel). The time is up in a time equivalent to one lap). Therefore, normally, when monitoring the 504 pulse time with a timer, a capacity of 2 bytes is required. However, by counting the timer only during the two-phase excitation state, a storage capacity of 1 byte is sufficient, and the storage capacity is reduced Is possible. When bit 0 of the counter value of the excitation output counter is 1 (step S232), and it is determined that the one-phase excitation state is present, the error timer is not incremented by 1 (step S233), and the process proceeds to step S235. In FIG. 22, the time-up of the error timer is represented as “0” in the sense of the subtraction count value 0. Further, in this embodiment, the rotation of the rotating cylinder is detected based on the detection of the two-phase excitation state for 256 steps. However, the abnormality of the rotation of the rotating cylinder is detected based on the detection of the one-phase excitation state for 256 steps. Detection can be performed.

  When the error timer is not 0 (step S234), it is determined whether the reel position detection sensor is on or off (step S235). When the reel position detection sensor (rotor rotation position detection sensors 254 to 256) is detected to be turned on due to the passage of the light shielding piece of the reel, it is determined that the rotation is normal and the error timer is cleared (steps S235 and S236). After confirming that normal forward rotation is being performed by turning on the reel position detection sensor, the rotation sensor ON flag is turned on (step S237), and the pressing operation of the rotation rotation stop buttons 16a to 16c is effective. Move to the stop control state. The rotational shift movement of each reel symbol in the steady forward rotation state from the time point when the reel position detection sensor is turned on is strictly controlled. Since the reel rotation reference position is detected by turning on the reel position detection sensor, 24 is set in the symbol step number counter and the symbol counter is also set to 0, and the reel position initialization process is performed (step S238). ). Next, the process proceeds to step S222, where 1 is added to the excitation output counter, excitation data corresponding to the counter value of the excitation output counter is acquired based on the excitation output table, and the excitation output data set in the output buffer is updated. Is performed (steps S223 to S225).

  If the reel position detection sensor is off in step S235, the process proceeds to step S240 in FIG. In steps S240 to S245, a reel position update process is executed. The counter value of the symbol step number counter is decremented by 1 (step S240), and it is determined whether or not the value of the symbol step number counter is 0 (step S241). When the value of the symbol step number counter is not 0, the process proceeds to step S222, and the above-described processing for updating the excitation output data is performed (steps S222 to S225).

  When the value of the symbol step number counter is 0, it is determined that the reel has rotated by one symbol, and 24 is set in the symbol step number counter (step S242). Next, 1 is added to the symbol counter (step S243). It is determined whether or not the value of the symbol counter has reached 21 (step S244). When 21 has been reached, it is determined that the reel has made one revolution, the symbol counter is set to 0 (step S245), and step S222. Then, the excitation output data update process is performed (steps S222 to S225). When the value of the symbol counter has not reached 21 (step S244), the symbol counter value is not initialized, and the process proceeds to step S222 to perform excitation output data update processing (steps S222 to S225).

  As a result of determining that the two-phase excitation state is obtained from the counter value of the excitation output counter in step S233 and adding the error timer (step S234), the error timer is set to 0 without detecting the reel position detection sensor ON (step S235). When the time is reached (time is up), that is, when the 256-phase two-phase excitation state is detected, the reel rotation reference position is not detected even though the reel makes one rotation. In this case, there is a possibility that a rotation error state in which the rotation of the rotating drum is locked for some reason and the rotation becomes impossible is generated. At this time, the process proceeds from step S234 to step S227, and the rotation rotation start control process is executed again to restart. If the error is not resolved even after restarting several times, an error notification may be issued.

  When the spinning cylinder steady rotation state is continued by turning on the spinning cylinder sensor ON flag (step S237), when the spinning cylinder rotation stop buttons 16a to 16c are pressed, the stop signal detection flag for each reel that has been stopped is displayed. Turn on. When the stop signal detection flag is turned on (step S231), the process proceeds to step S239 in FIG. Even if the rotation rotation stop buttons 16a to 16c are pressed, the rotation rotation is not stopped immediately, but the stop symbol based on the stop control table is determined according to the internal lottery result, and the stop symbol slips to the stop position. The number of sliding pieces to go is determined. After the stop operation, the stop command flag is turned on when the stop symbol slips to a predetermined stop position. When the stop signal detection flag is turned on, the rotation abnormality detection process after step S232 is not performed, and the reel position update process after step S240 is continuously performed until the stop command flag is turned on. The generation of the stop signal detection flag and the stop command flag is performed in the spinning cylinder stop process (step S8 in FIG. 8).

  FIG. 26 shows details of the rotating cylinder stop process (step S8). FIG. 27 shows a symbol stop control process in the rotating cylinder stop process. The rotating cylinder stop process will be described in detail below with reference to FIGS.

  In the loop processing of steps S301 to S304, it is determined whether or not the rotating reel is in a normal spinning rotation state in which a stop operation can be performed. The number of loops “3” for three times of the body is set (step S300). Next, it is determined whether or not the rotation state flag is turned on for the first spinning cylinder (step S301), and when it is on, it is judged whether or not the spinning sensor ON flag is turned on (step S302). The rotation state flag is turned on in step S55 in the above-described rotating drum rotation start setting process. When the reference position of the rotating reel is not detected by the reel position detection sensor, the rotation sensor ON flag is not turned on. Therefore, when the rotation sensor flag is on, the rotation sensor ON flag is not turned on. The process returns to step S300.

  When the rotation state flag and the rotation sensor ON flag are on, the loop number is subtracted by 1 (step S303). When the turning sensor ON flag is detected, the turning device can be stopped. After the subtraction, it is determined whether or not there is a remaining number of loops (step S304). If there is a remaining number, the loop processing of steps S301 to S304 is repeated. When there is no remaining number of loops, the loop process is finished (step S304), and the process proceeds to step S305. When the loop process ends, it is determined that all the reels that are rotating are rotating normally.

  After the end of the loop process, it is determined whether or not an invalid stop operation has been performed (step S305) before the presence / absence of an effective stop operation by the rotation rotation stop buttons 16a to 16c is determined (step S306). The invalid stop operation content is, for example, an irregular stop operation in which the reel rotation stop button corresponding to the reel is pressed many times even though the reel is stopped. When an invalid stop operation is performed, the process returns to step S300, and it is determined again whether all the rotating reels are rotating normally. When an invalid stop operation is not performed, the presence / absence of an effective stop operation is determined (step S306). If an operation of the rotating drum rotation stop button corresponding to the reel being rotated is performed, it is determined that an effective stop operation has been performed, and the stop signal detection flag is turned on (step S307).

  Next, stop order data for three reels, number of symbol stops, stop target reel number, and stop interval time (211 ms) between reels of the stop interval timer are set (step S308). The stop order data is data indicating the pressing order of the stop operation, and is used for stop control. The symbol stop number is data indicating the number of reels that are stopped, and is used for stop control and determination in step S311. The stop target reel number is data indicating the current stop target reel, and corresponds to “2” when the middle reel stops this time, “1” when it is left, and “3” when it is right. Used in rotation control. The stop interval timer is a timer for managing the time until the next stop operation becomes valid, and is used in the determination in step S310. Stop order data, symbol stop count, stop target reel number, and stop interval time data are set in the stop order data memory area, symbol stop count memory area, stop target reel number memory area, and stop interval timer area of the main RAM 104, respectively. The After these data settings, the symbol stop control process (step S309) is executed. The stop order data is provided to the sub-control unit as push order data for the stop operation.

  In the present embodiment, among the number of symbol steps for one symbol, 11 to 24 are stop processable positions, and 1 to 10 are stop process impossible positions. Therefore, in the symbol stop control process (step S309), first, when stop control is started (when a stop operation is detected) in order to make the symbol position in the reel window at the time of stop constant during the stop process. Then, it is confirmed whether the number of symbol steps is 11 or more (step S350).

  When the number of symbol steps is less than 11, it waits until the symbol counter is updated to the next symbol. Since the number of symbol steps becomes 24 for the next symbol, the condition of 11 or more is satisfied, and the number of sliding symbols is calculated (steps S350 and S351).

  In the sliding piece number calculation process, the number of sliding pieces corresponding to the winning combination, stop order data, etc. is determined based on a stop control table (not shown) stored in the main ROM 103. The number of sliding frames is selected in the range of 0 to 4 (within the 4-frame limit area). The number of sliding symbols selected in the number of sliding symbols calculation process is acquired (step S352), and if the number of sliding symbols is not zero, the symbol counter is monitored until it becomes zero (steps S353 to S355). When the number of sliding pieces becomes 0, the stop command flag is turned on (steps S353 and S356).

  After performing the symbol stop control process (step S309) of FIG. 27, the stop interval time is measured by the stop interval timer, and the elapse of the set stop interval time is monitored (step S310). It is determined whether or not (step S311). When all the reels are stopped, the rotation stopping process is finished.

  The process during the rotation stop will be described below. It is determined whether or not the spinning cylinder stopping flag is turned on. If the rotating cylinder suspension flag is set (step S207), it is determined whether or not the value of the motor output timer is 0 (step S208). The motor output timer is set to “150” based on the excitation output time data table when the acceleration process is completed. For this reason, since the motor output timer is not 0 in the first turning cylinder stop process, the processes after step S209 are executed. When the value of the motor output timer is not 0, 1 is subtracted from the value of the motor output timer, and the excitation output data is set to “0F” (steps S209 and S210). By setting the excitation output data to “0F”, the stepping motor is turned on for all phases. Next, it is determined whether or not the value of the motor output timer is 0 (step S211). If the value of the motor output timer is not 0, excitation output data “0F” is stored in the output buffer corresponding to the reel (step S224). Further, if the reel rotation control process for all reels has not been completed (step S225), the process returns to step S200. Since the motor output timer becomes 0 when the interrupt processing is performed 150 times, the all-phase on state is continued for 150 × 1.5 ms (all-phase holding time), and the rotation is stopped. When it is determined in step S208 and step S211 that the value of the motor output timer is 0, it is determined that the stop control is completed, and “00” is set in the excitation output data (step S212). By setting the excitation output data to “00”, the stepping motor is turned off in all phases (non-driving state) and is completely stopped. With the complete stop of the stepping motor, the spinning cylinder control flag is turned off (step S213).

  The reel position update process is continued (steps S240 to S245, S222 to S225) until the stop command flag is turned on (step S356) by the spinning stop process. Even if the number of sliding pieces to the predetermined stop position slips and the stop command flag is turned on (step S239), the reel position update process is continued until the stop position is reached (steps S239 and S246). ). The stoppable position is determined by determining whether the counter value of the number of symbol steps is less than 9 and whether the two-phase excitation state is present (step S246). If it is less than 9 (8) and the one-phase excitation state is set, the next position with the number of symbol steps of 7 becomes the stoppable position. When the stoppable position is reached, the spinning cylinder stop flag is turned on (step S247).

  The present invention is not limited to the above-described embodiments and modifications, and includes various modifications and design changes within the technical scope without departing from the technical idea of the present invention. Needless to say.
