Hereinafter, a combination of symbols that is aligned with any of the invalid lines LM1 to LM4 when a predetermined symbol combination is aligned with the winning line LN is referred to as a symbol combination serving as an index, and constitutes a symbol combination serving as an index. The symbol is called an index symbol.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L, 2C, and 2R rotate, and the symbols of the reels 2L, 2C, and 2R continuously vary. When any one of the stop switches 8L, 8C, 8R is operated in this state, the rotation of the corresponding reels 2L, 2C, 2R is stopped, and the display result is derived and displayed on the fluoroscopic window 3.

  Then, when all the reels 2L, 2C, 2R are stopped, one game is completed, and a predetermined symbol combination (hereinafter also referred to as a winning combination) is displayed on the reels 2L, 2C, 2R on the winning line LN. If the game stops as a result, a winning occurs, and a predetermined number of medals are given to the player and added to the credit. Further, when the credit reaches the upper limit number (50 in this embodiment), medals are paid out directly from the medal payout opening 9 (see FIG. 1). In addition, when the combination of symbols accompanying the transition of the gaming state on the winning line LN is stopped as a display result of each reel 2L, 2C, 2R, the gaming state according to the combination of symbols is shifted. .

  In this embodiment, the game starts when the operation of the start switch 7 is detected in a state where the operation of the start switch 7 is valid, and the game ends when all the reels are stopped. Further, one unit of control (game control) for executing a game starts when all the controls associated with the end of the previous game are completed, and when all the controls associated with the end of the game are completed. finish.

  In this embodiment, a configuration using three reels is illustrated, but a configuration using only one reel, a configuration using two reels, a configuration using four or more reels may be used. In the configuration using two or more reels, a winning determination may be made based on a combination of display results derived for all two or more reels. In this embodiment, the variable display device is configured by physical reels. However, the variable display device may be configured by an image display device such as a liquid crystal display.

  In the slot machine 1 according to the present embodiment, after the game is started and the reels 2L, 2C, and 2R are rotated and the symbols start to change, any one of the stop switches 8L, 8C, and 8R is operated. When this is done, the rotation of the reels corresponding to the stop switches 8L, 8C, 8R is stopped, and the symbols are stopped and displayed. When the gaming state is a gaming state other than CT (challenge time), which will be described later, from when the stop switches 8L, 8C, 8R are operated until the corresponding reels 2L, 2C, 2R stop rotating. The maximum stop delay time is 190 ms (milliseconds). On the other hand, when the gaming state is CT, for a specific reel, the maximum stop delay time from when the stop switch corresponding to the reel is operated until the rotation is stopped is 75 ms (milliseconds). Limited. Even if the gaming state is CT, except for the specific reel, the operation of the stop switches 8L, 8C, 8R is performed in the same manner as in the gaming state other than CT, and the corresponding reels 2L, 2C, 2R The maximum stop delay time until the rotation is stopped is 190 ms (milliseconds).

  The reels 2L, 2C, and 2R are rotated 80 times per minute, and 80 × 20 (the number of symbols per reel) = 1600 frames is changed, so that the gaming state is a gaming state other than CT. During the maximum stop delay time (190 ms) and the maximum stop delay time (190 ms) other than the specific reel when the gaming state is CT, a maximum of four symbols can be drawn. In other words, the symbols that can be selected as the stop symbols are the symbols that are displayed when the stop switches 8L, 8C, and 8R are operated, and the symbols that are four frames ahead of them, for a total of five symbols. On the other hand, a symbol of one frame can be drawn at maximum during the maximum stop delay time (75 ms) of the specific reel when the gaming state is CT. In other words, the symbols that can be selected as the stop symbol are the symbol that is displayed when the stop switch is operated, and the symbol that is one frame ahead, that is, a total of two symbols.

  For this reason, for example, when any of the stop switches 8L, 8C, 8R is operated, it is based on the symbol displayed on the lower stage of the reel corresponding to the stop switch, and the gaming state is other than CT. In the gaming state, except for the specific reel when the gaming state is CT, the symbols from the reference symbol up to 4 frames ahead can be displayed in the lower stage, so that each reel 2L, 2C, 2R When any of the stop switches 8L and 8R is operated, the symbols arranged within 5 frames including the symbols displayed on the winning line of the reel corresponding to the stop switch are displayed on the winning line. Can be displayed. On the other hand, when the gaming state is CT, for a specific reel, the maximum stop delay time from when the stop switch is operated until the rotation is stopped is limited to 75 ms (milliseconds). For a specific reel, when the stop switch is operated, the symbols arranged within one frame including the symbols displayed on the winning line of the reel corresponding to the stop switch are displayed on the winning line. The reels other than the specific reel are displayed on the winning line of the reel corresponding to the stop switch when the stop switch is operated, as in the case where the gaming state is a gaming state other than CT. The symbols arranged within 5 frames including the symbols can be displayed on the winning line.

  Hereinafter, the reels 2L, 2C, and 2R may be simply referred to as reels unless it is necessary to distinguish between them. Further, the reel 2L may be referred to as a left reel, the reel 2C as a middle reel, and the reel 2R as a right reel. Further, an operation for stopping the reels 2L, 2C, 2R by operating the stop switches 8L, 8C, 8R may be referred to as a stop operation.

  An effect switch 56 is connected to the effect control board 90, and a detection signal of the effect switch 56 is input. In addition, presentation devices such as a liquid crystal display 51, presentation effect LEDs 52, speakers 53 and 54, and reel LEDs 55 are connected, and these presentation devices are controlled by a later-described sub-control unit 91 mounted on the presentation control board 90. It is driven based on this. In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to the set value in a lottery that affects the advantage to the player, such as an internal lottery, a navigation stock lottery, and an extra lottery to be described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the changed state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the set value display 24 is updated one by one (when the set value 6 is further operated, the set value 1 is set. Return). When the start switch 7 is operated, the display value is determined as the set value. When the setting key switch 37 is turned off, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In the slot machine 1 of the present embodiment, a prescribed number of bets that can be set according to the gaming state is determined, and the game is performed on the condition that the prescribed number of bets determined according to the gaming state is set. Can be started. In the present embodiment, the winning line LN is activated when a specified number of bets according to the gaming state are set.

  In this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line is activated (in the present embodiment, all the pay lines LN are always activated. An activated winning line is simply referred to as a winning line). The combination may be a combination of the same symbols or a combination including different symbols.

  The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition to a game state advantageous to the player. Below, a small role and a re-playing role are collectively called a general role. In order to win each winning combination determined according to the gaming state, it is necessary to win the internal lottery and set the winning flag of the winning combination in the RAM 41c. In the internal lottery, whether or not the main control unit 41 allows the winning of each combination described above before the display results of all the reels 2L, 2C, and 2R are derived (specifically, the start switch 7 Is determined using a random number. Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is invalid in the next game. It is valid until a combination of combinations permitted by the flag is completed, and is invalid in a game having a combination of combinations permitted. In other words, once the special combination winning flag is won, even if the combination of the combinations permitted by the flag cannot be made, the winning flag is not invalidated and is carried over to the next game. It becomes.

  The main control unit 41 of this embodiment can control the CB as a gaming state advantageous to the player by winning a special role. During CB, each game CT is controlled until the CB termination condition is satisfied.

  When the gaming state is CT, winnings of all small roles are allowed, but for a predetermined specific reel, from the timing when the stop switch is operated to the timing when the reel is controlled to stop. The maximum delay time is shortened to be limited to a prescribed time (in this embodiment, 75 milliseconds). That is, in CT, although all small combinations are allowed, the number of frames drawn when a stop operation is performed on a specific reel is limited to a predetermined number. Demands high technical intervention.

  Next, stop control of the reels 2L, 2C, 2R will be described. The main control unit 41 displays the winning number, the table index stored in the ROM 41b, and the table creation data when the rotation of the reel starts and when the reel stops and the reel that is still rotating still remains. Referring to this, a stop control table is created for each reel that is rotating. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In this embodiment, when the gaming state is a gaming state other than CT, a value of 0 to 4 is determined as the number of sliding symbols for a specific reel when the gaming state is CT, and a stop operation is detected. It is possible to stop the reel by drawing up to 4 symbols. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In this embodiment, when the gaming state is a gaming state other than CT, and any of the winning combinations is won, a maximum of four frames on the winning line will be displayed when the stop operation is performed. If the winning combination in the drawing range can be aligned and stopped, control is performed to align and stop the winning combination, and the unselected winning combination is controlled to stop without aligning in the drawing range of up to 4 frames. Will be.

  On the other hand, when the gaming state is CT, regardless of the result of the internal lottery, when a stop operation is performed, for a specific reel, one of the small roles in the drawing range of up to two frames on the winning line If it can be stopped by aligning them, control is performed to align and stop them. For reels other than the specified reels, any small part must be aligned and stopped on the winning line within a maximum of 4 frames. If it is possible, control is performed to stop them together. If a re-gamer is won in the internal lottery, as with the small role, for the specified reel, the re-gamer won in the draw line of up to 2 frames on the winning line will be stopped. If it is possible, control is performed to align and stop the reels. For reels other than the specific reel, if the re-games can be aligned and stopped within the maximum draw range of 4 frames on the winning line, they are aligned and stopped. The re-gamer who is not elected is controlled to stop without aligning within a maximum 2 frame pull-in range for specific reels, and up to 4 frame pulls for reels other than the specific reels. Control to stop without aligning in the range will be performed. In this embodiment, when the gaming state is CT, the special combination is not won, and the special combination is controlled so that the specific reel is stopped without being aligned within the drawing range of a maximum of two frames. For reels other than the reels, control is performed to stop the reels without aligning them in the drawing range of a maximum of 4 frames.

  In this embodiment, the reel stop control is performed by using a stop control table that can specify the number of sliding frames for each timing at which the stop operation is performed. A configuration that performs stop control by specifying the stop position from the table and stopping the reel at the specified stop position, and searching for a stop position that can be stopped when the stop operation is performed without using the stop control table or the stop position table. A configuration that performs stop control that identifies and stops the reel at the specified stop position, stop control using the stop control table, stop control using the stop position table, and can be stopped without using the stop control table or the stop position table A configuration that uses stop control by searching and specifying the stop position together, and a configuration that performs stop control by partially changing the stop control table and stop position table. It may be.

  Next, the configuration of the reel motors 32L, 32C, and 32R and a control method for exciting the reel motor will be described with reference to FIGS.

  FIG. 4 is a diagram illustrating a configuration of the reel motors 32L, 32C, and 32R. The reel motors 32L, 32C, and 32R are hybrid type stepping motors, and include a stator 32b and a rotor 32a facing the stator 32b. The rotor 32a has a large number of gear-shaped salient poles (not shown), and permanent magnets magnetized in the same direction as the rotation shaft are incorporated therein. These reel motors 32L, 32C, and 32R receive a pulse signal output from the motor drive circuit 45 based on the control of the main control unit 41, and the excitation phases φ1 to φ4 of the stator 32b are excited according to a predetermined procedure. Every time one pulse is received, the rotor 32a rotates by a predetermined angle (one step).

  FIG. 5A is a timing chart showing a control method when starting the reel motors 32L, 32C, and 32R. In the figure, φ1 to φ4 indicate each excitation phase, “ON” indicates an excitation state, and “OFF” indicates a demagnetization state. When starting the reel motors 32L, 32C, 32R, the main control unit 41 starts excitation in the rotational direction by a 1-2 phase excitation method, which will be described later, starting from the state where only the stop phase is excited. Specifically, for example, when the stop phase is (φ3, φ4), φ1 in the order of (φ4), (φ4, φ1), (φ1)... From the state where (φ3, φ4) is excited. ˜φ4 is excited alternately with one phase, two phases, and one phase.

  If the excitation is started with a phase different from the stop phase as a starting point, the permanent magnet of the rotor 32a is suddenly attracted to the excitation phase, and the reel vibrates at the start of rotation. In the present embodiment, since the excitation is started from the stop phase as a starting point, the reel integrally coupled with the rotor 32a starts smoothly.

  FIG. 5B is a timing chart showing a control method during rotation and stop of the reel motors 32L, 32C, 32R.

  First, during the rotation, that is, until the condition for stopping the reel is satisfied, the reel motor is driven by the 1-2 phase excitation method to rotate the reels 2L, 2C, and 2R. For example, a pulse signal indicating excitation of φ1 to φ4 is turned ON / OFF at the timing shown in FIG. 5B, and (φ4, φ1), (φ1), (φ1,. (φ2), (φ2), (φ2, φ3), (φ3), (φ3, φ4), (φ4), (φ4, φ1)... in this order, two phases, one phase, two phases, one phase The reels 2L, 2C, and 2R are rotated by rotating the rotor 32a by exciting [phi] 1 to [phi] 4 alternately every two phases.

  Next, when the condition for stopping the rotating reel is satisfied, the process proceeds to reel stop control. For example, when the condition for stopping the reel is established in the period shown in FIG. 5B as the stop condition establishment step, until the point Ta when the phase shifts to the state where the two-phase excitation method is excited in the 1-2 phase excitation method. Wait and shift to stop control.

  The reel stop control is performed by the all-phase excitation stop control as shown in FIG. In the all-phase excitation stop control, when the reel motor is driven by the 1-2 phase excitation method, it starts from the point Ta when the state is excited from the state in which one phase is excited to the state in which two phases are excited. In this control, the state to be held is held for a predetermined hold time (T1 + T2). For example, as shown in FIG. 5B, the state in which (φ1, φ2, φ3, φ4) is excited is held from the time when (φ1, φ2) is excited to the state where (φ1, φ2) is excited. Hold for time T1 + T2. As a result, rapid braking is applied to the rotor 32a of each reel motor that has been rotating at a high speed. Thereafter, the rotor 32a of the reel motor rotates by several steps (in this embodiment, 4 steps) by the inertia force and stops. Note that the number of steps required for the reel motor rotor 32a to stop varies depending on the characteristics of the reel and reel motor (weight, size, electromechanical properties). It is preferable to perform all-phase excitation stop control with a corresponding number of steps.

  After all-phase excitation stop control is executed for T1 + T2 (Tc), φ1 and φ2 are demagnetized, and the voltage applied to the reel motor is maintained at the normal value (high state) while the excitation states of stop phases φ3 and φ4 are maintained. (Low state). Even after the rotor 32a is stopped, the excitation state of the stop phases φ3 and φ4 is maintained at a voltage that is lower than the normal value because the rotor 32a has a phase difference between the holding torque and the detent torque and a shift due to the influence of friction. This is to prevent the stop phases φ3 and φ4 from deviating from the holding torque stable point. As a result, it is possible to prevent the reel from moving finely after being temporarily stopped and the angular position of the rotor 32a when starting the reel motor next time from being deviated from the angular position at the time of stopping.

  The excitation states of the stop phases φ3 and φ4 that are maintained even after the rotor 32a is stopped are a predetermined time (30 seconds in this embodiment) without performing the next game start operation, and shift to a standby state (demonstration effect). Is released when the same timing has elapsed (Td). That is, after the rotor 32a is stopped, when a predetermined time has passed without the start operation of the next game being performed, all of φ1 to φ4 are demagnetized. For this reason, for example, there is no burden on the components and the like constituting the stepping motor due to the heat generated when the excitation phase is continuously excited for a long time, so that deterioration of these components can be prevented. Further, in this embodiment, the excited state is released at the timing when the state in which the next game start operation is not performed continues for a predetermined time and shifts to the standby state (demonstration effect), so that while the player is playing Can maintain a state in which the symbols arranged on the reels are not easily displaced, while it is possible to reduce the load on the components of the stepping motor in a state where the possibility that the player is playing is low.

  Next, a main process executed by the main control unit 41 as a basic process and a reel control process executed in the main process will be described with reference to FIGS. The main process is repeatedly executed for each unit of game. One period of the main process corresponds to one unit of the game.

  As shown in FIG. 6, in the main process, a game start waiting process (Sa1) that waits until a game is started, an internal lottery process (Sa2) that performs an internal lottery as the game starts, a reel 2L, Reel control process (Sa3) for performing control to rotate and stop 2C, 2R, and game end setting process (Sa4) for performing various settings when all the reels 2L, 2C, 2R are stopped and the game is ended Are sequentially repeated.

  The reel control process executed in the main process includes the reel rotation start process for starting the rotation of each reel 2L, 2C, 2R and the corresponding reels 2L, 2C, 2R in response to the operation of the stop switches 8L, 8C, 8R. Including a reel rotation stop process for stopping the process, and is executed after the internal lottery process in the main process. FIG. 7 is a flowchart showing the control content of the reel control process executed by the main control unit 41, and FIG. 8 is a flowchart showing the control content of the reel rotation stop process executed by the main control unit 41 in the reel control process. 9 is a diagram for explaining the relationship between the allocation of the number of symbol steps and the determination range in the reel rotation stop process. FIG. 10 is a stop control table setting process executed by the main control unit 41 in the reel control process. It is a flowchart which shows the control content of.

  As shown in FIG. 7, in the reel control process, first, a reel rotation start process is executed (Sb1), the reels 2L, 2C, and 2R are started to proceed to the step of Sb4. In step Sb4, a timer interruption waiting process is executed. In the timer interruption waiting process, the timer interruption is set to be permitted, and the process waits until the timer interruption process (main) is performed once.

  When it is determined that a rotation error has occurred in the reel after the timer interruption waiting process in step Sb4 is completed (Sb12), the reel stop operation during the rotation control is set invalid (Sb13). Then, error processing is executed (Sb17). In the error processing, all the reels are stopped from rotating and controlled to an error state that disables the game from proceeding and waits. Thereafter, the error state is canceled by a reset operation, and the error process is terminated, and the acceleration process is performed again to accelerate the reel again (Sb19).

  If it is not specified that a rotation error has occurred (Sb12), the timer interrupt is disabled (Sb21), and then updated by a timer interrupt process (main), which will be described later, in a predetermined area of the RAM 41c. (Sb22), based on the reel speed state flag, it is determined for each reel whether or not the rotation state of the reel under rotation control is a constant speed state. It is determined whether or not all reels under rotation control are rotated at a constant speed (Sb23). If it is determined in step Sb23 that at least one of the reels is not rotating at a constant speed and all reels under rotation control are not rotating at a constant speed, Sb4 Returning to the step, the steps Sb4 to Sd23 are repeatedly executed, and the process waits until all reels under rotation control are rotated at a constant speed. Note that the reel speed state flag is updated in a timer interrupt process (main) described later, and each reel motor under rotation control at the time when the timer interrupt process (main) is performed rotates in a constant speed state. It is the information that can specify whether or not.

  After returning to the step of Sb4 and repeatedly executing the steps of Sb4 to Sd23 and waiting, the timer interruption process (main) executed in the timer interruption waiting process of the step of Sb4 is performed for all reels under rotation control. By updating the reel speed state flag so that it can be specified that the rotation state is a constant speed state, all the reels that are under rotation control are rotated at a constant speed rotation in the subsequent step Sb23. It will be determined.

  On the other hand, if it is determined in step Sb23 that all the reels under rotation control that have not been stopped are rotated at a constant speed, the predetermined time is determined based on the valid timer set in the RAM 41c. When it is determined that the time has elapsed (Sb27), the acceptance of the stop operation is set to be valid for all the reels for which the rotation control is performed (Sb28). In addition, when the acceptance of the stop operation is already set to be valid for the reel that is performing the rotation control, the valid state is maintained. If it is determined in step Sb27 that the predetermined time has not elapsed based on the valid timer, steps Sb4 to Sb27 are repeatedly executed, and the process waits until the predetermined time elapses.

  Then, after the acceptance of the stop operation is set to be valid in the step of Sb28, it is determined whether or not an effective stop operation has been detected in a state where the acceptance of the stop operation is valid for the reel under rotation control (Sb29). . That is, when the port input data of the stop switch is in the same state in the timer interruption process (main) for a predetermined number of times (in this embodiment, twice), it is set in a predetermined area of the RAM 41c, and the current and previous input data Referring to the history of confirmed data indicating that the same state is present, if there is a stop switch in rotation control where the confirmed data has changed from the off state to the on state, the confirmed data from the off state It is determined that an effective stop operation has been detected for the stop switch that has changed to the on state. As a result, an effective operation for the stop switch is detected on the condition that the on-state of the stop switch has been continuously detected for a certain period (at least about 2.24 ms) or longer. It is possible to prevent the ON state from being erroneously detected due to noise.

  In this embodiment, it is detected that the fixed data of the stop switch is changed from the off state to the on state in a state where the stop operation is valid for the reels under rotation control, that is, a predetermined number of consecutive times. In the timer interrupt process (main), it is determined that a valid stop operation has been detected for the reel under rotation control by detecting the on state of the port input data, but one timer interrupt process ( A configuration may be adopted in which it is determined that a valid stop operation has been detected by detecting the on state of the port input data of the stop switch in the main).

  If it is determined in step Sb29 that an effective stop operation has not been detected, the process returns to step Sb4, and steps Sb4 to Sb29 are repeatedly executed until a valid stop operation is detected. After that, if a valid stop operation is detected in step Sb29, the stop operation-related process 1 is executed in the state where the timer interrupt is prohibited in step Sb21 (Sb30), and then the timer interrupt is permitted. (Sb31) and stop operation related processing 2 is executed (Sb32). In the stop operation related process 1, the stop valid LED corresponding to the stop switch for which the stop operation has been performed is set to be extinguished, the valid timer set in a predetermined area of the RAM 41c is initialized, and effective in the step of Sb28. Processing for starting measurement of the elapsed time after the stop operation is detected is performed. In the stop operation related process 2, a process of setting the reception of the reel stop operation corresponding to the valid stop operation detected in step Sb29 to be invalid is performed. When the timer interrupt is set to enable in the step Sb31, the original timer interrupt timing is included in the period in which the timer interrupt is disabled over the steps Sb21 to Sb30. If the timer interrupt is enabled in the step Sb31, the timer interrupt process (main) is executed, while the original timer interrupt timing is included in the period. If not, then the timer interrupt process (main) is executed at the timing of the timer interrupt.

  Then, after the stop operation related process 2 is completed in the step of Sb32, a reel rotation stop process described later is executed (Sb33), and the reel corresponding to the effective stop operation detected in the step of Sb29 is stopped. Take control. Thereafter, a stop control table setting process to be described later is executed (Sb34), and a stop control table is set for the remaining reels under rotation control. After executing the stop control table setting process, it is determined whether or not the reel for which the stop operation has been detected is stopped in step Sb29 (Sb35), and if it is determined that the reel is not stopped, It waits until the reel stops, and when it is determined that the reel is stopped, it is determined whether or not an effective stop operation has been performed for all the reels 2L, 2C, 2R (Sb36). If all the reels 2L, 2C, and 2R are not stopped, the process returns to the step Sb2, and the control of the steps Sb2 to Sb36 is executed for the remaining reels that are not stopped.

  Then, if an effective stop operation is performed for all the reels 2L, 2C, and 2R, and it is determined in step Sb35 that all the reels 2L, 2C, and 2R are stopped, after executing the timer interruption waiting process (Sb37), it is determined whether or not the stop switch of the third stop is being operated, that is, whether or not the pressing of the stop switch of the third stop is terminated and the confirmed data of the stop switch is in the off state. (Sb41) If the stop switch is being operated, the system waits until the operation is completed. Then, after the determination data of the stop switch is in the off state and it is determined that the stop switch is not being operated, the reel control process is terminated and the process returns to the main process. In this embodiment, the confirmed data of the third stop switch is in the off state, that is, the off state of the port input data is detected in a predetermined number of consecutive timer interrupt processes (main). In this configuration, it is determined that the stop switch of the third stop is not in operation. However, when the off state of the port input data of the stop switch is detected in one timer interrupt process (main), the stop switch The configuration may be such that it is determined that the operation is finished.

  Next, the reel rotation stop process executed by the main control unit 41 in the reel control process will be described.

  As shown in FIG. 8, in the reel rotation stop process, first, the timer interrupt is disabled (Sd1), and then the reel control process is performed based on the symbol step number counter set in a predetermined area of the RAM 41c. The number of symbol steps of the reel in which the stop operation is detected in step Sb28 is acquired (Sd2), and a predetermined determination range (0 to 11 steps or 0 to 12 steps) in which the number of symbol steps is set in a predetermined area of the RAM 41c. ) Is determined (Sd3).

  As shown in FIGS. 9A and 9B, the number of symbol steps is the number of steps corresponding to one symbol out of the number of steps of one revolution of the reel motor (336 steps in this embodiment). In this embodiment, 16 steps are assigned to 4 symbols out of 20 symbols arranged on one reel, and 17 steps are assigned to 16 symbols out of 20 symbols.

  As shown in FIG. 9A, for a symbol to which 16 steps are assigned, the lower end of one symbol is 0 step (first step) and the upper end is 15 steps (16th step). Further, as shown in FIG. 9B, for a symbol to which 17 steps are assigned, the lower end of one symbol is 0 step (first step) and the upper end is 16 steps (17th step). . The symbol step number counter is a predetermined determination position of the reel (in this embodiment, the position of the uppermost end of the symbol area corresponding to the symbol located in the middle stage when each reel 2L, 2C, 2R is stopped, FIG. The counter corresponding to each reel is set in a predetermined area of the RAM 41c, and any of the symbol step counters is a timer interrupt process (main). It is updated by an update process such as the number of reel steps executed in. This symbol step number counter is incremented by 1 each time a timer interrupt process is performed, and on the basis of a symbol number counter described later, a symbol to which 16 steps are assigned passes the determination position. When specified, it is initialized to 0 when the value of the symbol step counter becomes 16 steps, and when it is specified that the symbol to which 17 steps are assigned passes the judgment position. When the value of the symbol step counter becomes 17 steps, it is initialized to 0, and 0 to 15 steps or 0 to 16 steps can be counted for each symbol.

  Further, as shown in FIGS. 9A and 9B, a determination range and a non-determination range are set for the number of symbol steps. The determination range is that a symbol with a symbol number specified based on the value of the symbol number counter at the time when the value of the symbol step counter is acquired is a predetermined stop position (in this embodiment, a reel In the present embodiment, for symbols assigned with 16 steps, the reel rotation direction front side of the 16 steps assigned to one symbol in this embodiment. 0 to 11 (first to twelfth steps) of steps, and for symbols to which 17 steps are assigned, among the 17 steps to be assigned to one symbol, 0 to 12 ( 1st to 13th steps) The range of steps. On the other hand, the non-determination range is a symbol with a symbol number specified based on the value of the symbol number counter at the time when the symbol step number counter value is acquired. Is the range of the number of symbol steps that cannot be stopped at the middle position of the reel. In this embodiment, for symbols to which 16 steps are allocated, the rotation direction of the 16 steps allocated to one symbol For the symbols in the rear 12 to 15 steps (13th to 16th steps) to which 17 steps are assigned, among the 17 steps assigned to one symbol, 13 to 16 on the rear side in the rotational direction. This is a range of steps (14th to 17th steps).

  In the reel rotation stop process, it is determined in step Sd3 that the number of symbol steps is not within a predetermined determination range (0 to 11 steps for 16-step symbols, 0 to 12 steps for 17-step symbols). In this case, once the timer interrupt (main) is set to be permitted (Sb4), the process returns to the step Sb1, and the steps Sd1 to Sd4 are repeatedly executed so that the number of symbol steps is within the predetermined determination range. Wait until it is determined. Note that after the timer interrupt (main) is disabled in the step Sd1, the timer interrupt is disabled in the steps Sd1 to Sd4 by setting the timer interrupt in the Sb4 step. If the original timer interrupt timing is included in the period during which the timer is interrupted, the timer interrupt processing (main) is executed when the timer interrupt is enabled in step Sd4. Thus, the symbol step number counter is updated in the reel step number updating process in the timer interruption process (main). On the other hand, if the original timer interrupt timing is not included in the period, the timer interrupt process (main) is executed when the timer interrupt is set to permit again, and the symbol step Update the number counter.

  On the other hand, if it is determined in step Sd3 that the number of symbol steps is within the predetermined determination range, the state in which the timer interrupt is disabled in step Sd1 is maintained, and the process proceeds to step Sd5, where RAM 41c The value of the symbol number counter set in the predetermined area is acquired, and the value of the symbol number counter is stored in the predetermined area of the RAM 41c as the symbol number when the stop operation is performed (hereinafter referred to as the symbol number during operation). Set (Sd6).

  Here, in this embodiment, each of the 20 symbols arranged on one reel is assigned in advance a symbol number (0 to 19) based on the symbol at the reel reference position as a symbol number. Is the symbol number of the symbol located at the predetermined determination position described above (in this embodiment, the position of the uppermost end of the region corresponding to the middle stage of each reel 2L, 2C, 2R in the see-through window 3, see FIG. 12). It is a counter for counting. One symbol number counter is set in a predetermined area of the RAM 41c for each of the reels 2L, 2C, 2R, and all the symbol number counters are updated by the reel step number updating process executed in the timer interrupt process (main). The Specifically, in the timer interrupt process, each symbol number counter is updated to be incremented by 1 when the symbol step number counter is initialized, and when the symbol number counter value reaches 21 The symbol number of the symbol located at the above-mentioned predetermined determination position matches the value of the symbol number counter. Thereby, the symbol number of the symbol which has passed the predetermined determination position based on the symbol number counter can be specified. In addition, each time the symbol number counter is updated, the timer interrupt process (main) specifies whether the symbol number is a 16-step symbol number or a 17-step symbol number based on the symbol number counter. And a determination range referred to in the reel stop rotation process (step Sb3) according to the specified symbol number (0 to 11 in the case of 16 step symbols, and 1 to 12 in the case of 17 step symbols). Is set in a predetermined area of the RAM 41c.

  Thereafter, a sliding frame number setting process for setting the number of sliding frames when stopping the corresponding reel is executed (Sd7). In the sliding frame number setting process, it is determined whether or not the gaming state is CT. If the gaming state is CT, it is determined whether or not the reel to be stopped is a specific reel. When the gaming state is CT and the reel to be stopped is a specific reel, from the stop control table set in the predetermined area of the RAM 41c by the stop control table setting process, the step Sb28 of the reel control process is performed. The stop control table for CT is specified among the stop control tables corresponding to the reel in which the stop operation is detected. On the other hand, if the gaming state is not CT, or the gaming state is CT, but the reel to be stopped is not a specific reel, a stop control table for non-CT is specified from the stop control table. Then, referring to the specified stop control table, the number of sliding symbols corresponding to the timing at which the stopping operation is performed is specified based on the operating symbol number, and the number of sliding symbols is set in a predetermined area of the RAM 41c. Further, in order to stop the corresponding reel at the position corresponding to the number of sliding symbols, that is, the symbol of the symbol number corresponding to the number of sliding symbols, a stop request is set in a predetermined area of the RAM 41c, and the corresponding reel is decelerated. The braking control to be stopped is started.

  Further, in the sliding frame number setting process, it is specified whether the number of steps assigned to the symbol of the symbol number corresponding to the sliding frame number is 16 steps or 17 steps. In the reel stop control, the all-phase excitation stop control starts the all-phase excitation of the reel motor at the number of symbol steps of 12 steps (the 13th step, and in the case of 16-step symbols, the step 4 steps before the final step). 1 is set in a predetermined area of the RAM 41c. On the other hand, if it is a 17-step symbol, it is determined whether or not the gaming state is CT. If the gaming state is not CT, the number of symbol steps is 13 steps (14th step) in the reel stop control. In the case of a 17-step design, a stop control flag B indicating that the all-phase excitation stop control 2 for starting the all-phase excitation of the reel motor is performed in a predetermined area of the RAM 41c in a step 4 steps before the final step). Set. When the gaming state is CT, the symbol number corresponding to the number of sliding symbols refers to either the all-phase excitation stop control 1 or the all-phase excitation stop control 2 with reference to the CT stop control table. Specify whether it is a symbol number. In the case of the symbol number for which the all-phase excitation stop control 1 is performed, in the reel stop control, the number of symbol steps is 12 steps (the 13th step, and in the case of 17 step symbols, 5 steps before the final step). When the stop control flag A indicating that the all-phase excitation stop control 1 for starting the all-phase excitation of the reel motor is performed is set in a predetermined area of the RAM 41c and the all-phase excitation stop control 2 is performed. In the reel stop control, the number of symbol steps is 13 steps (in the 14th step, and in the case of 17 step symbols, all phases that start the all phase excitation of the reel motor at the step 4 steps before the final step). A stop control flag B indicating that the excitation stop control 2 is performed is set in a predetermined area of the RAM 41c.

  As described above, the stop control flag A and the stop control flag B are set, and the symbol number corresponding to the number of sliding symbols is 16 step symbols by being referred to in the reel rotation control processing of the timer interrupt processing (main) described later. The reel motor drive signal is output so that all-phase excitation is started in the step four steps before the end of the symbol, regardless of whether the gaming state is CT or not. The Rukoto. In addition, when the symbol number corresponding to the number of sliding symbols is a symbol number of a 17-step symbol and the gaming state is a gaming state other than CT, all steps are performed four steps before the end of the symbol. A reel motor drive signal is output so that phase excitation is started. On the other hand, when the gaming state is CT, it is specified that the all-phase excitation stop control 1 is performed based on the CT stop control table, that is, one frame from the design when the stop switch is operated. If two frames of 17-step symbols are included in the pull-in range when the reels are pulled and stopped by sliding, and a specific condition described later can be satisfied, all-phase excitation stop control 1 is performed, so that the gaming state The reel motor drive signal is output so that all-phase excitation is started at a step five steps before the end of the symbol one step earlier than when the game state is other than CT. Further, even when the gaming state is CT, if it is specified that the all-phase excitation stop control 2 is to be performed based on the CT stop control table, that is, 1 from the pattern when the stop switch is operated. If the 17-step symbol included in the pull-in range when the reel is pulled and stopped by frame sliding is one frame and the specific condition described later cannot be satisfied, all-phase excitation stop control 2 is performed, As in the case where the gaming state is a gaming state other than CT, a reel motor drive signal is output so that all-phase excitation is started at a step four steps before the end of the symbol.

  The number of sliding symbols set in the predetermined area of the RAM 41c and the stop request are then referred to in the processing related to the rotation control of the reel motor in the timer interrupt processing (reel rotation control processing described later). When the symbol with the corresponding symbol number is located at the reel stop position and the symbol step number of the symbol reaches a predetermined number of steps (11 steps in this embodiment), the reel motor is energized in all phases. The reel is stopped at the symbol corresponding to the number of sliding symbols. In this embodiment, the symbol number of the symbol to be stopped on the reel can be specified based on the number of sliding symbols, and the symbol step number for the symbol to which the symbol number is assigned becomes a predetermined step number. The reel motor is energized in all phases, and the reel is stopped at a symbol corresponding to the number of sliding frames. The reel step number can be specified based on the number of sliding frames. The reel motor may be stopped at a stop position corresponding to the number of sliding frames by exciting all phases of the reel motor with a predetermined number of steps according to the number.

  After the sliding frame number setting process is executed in step Sd7, the timer interrupt is set to permit (Sd11). By setting the timer interrupt to enabled in the step of Sd11, the original timer interrupt timing is included in the period in which the timer interrupt is disabled over the steps of Sd1 to Sd9 or Sb10. If the timer interrupt is set to enable in step Sd11, the timer interrupt process (main) is executed, and the slip frame number setting process (Sb7) is performed in the timer interrupt process (main). The brake control for decelerating and stopping the corresponding reel is started based on the number of sliding symbols and the stop control flag set in (1). On the other hand, if the original timer interrupt timing is not included in the period, timer interrupt processing (main) is executed at the timer interrupt timing, and the corresponding reel braking control is started. To do.

  Then, after the timer interrupt is set to be permitted in step Sd8, stop position setting processing is executed (Sd9). In the stop position setting process, the symbol number of the position at which the reel is stopped based on the number of sliding symbols specified in the sliding frame number setting process of Sd6 and the symbol number at the time of operation (hereinafter referred to as stop position symbol), a predetermined number It is possible to specify a reel that is controlled to stop with the number of sliding frames, specify the symbol number of the reel and stop position symbol, and specify the number of sliding symbols specified in the sliding frame number setting process The command for the number of sliding frames is set in the command queue, and these commands are transmitted at the next timer interrupt.

  After executing the stop position setting process in step Sd9, refer to the reel control state flag that is set in a predetermined area of the RAM 41c in the reel rotation control process in the timer interrupt process (main) and that can specify the reel control state. (Sd10), it is determined whether or not the braking control for decelerating and stopping the reel for which the stop control is being performed is performed (Sd11). If the braking control is being performed, the reel rotation is performed. The stop process is terminated and the process returns to the reel control process. If it is determined that the braking control is not executed, the process waits until the braking control is executed. When it is determined that the braking control is executed, the reel rotation stop process is terminated and the reel control process is performed. Return.

  Next, the stop control table setting process executed by the main control unit 41 in the reel control process will be described.

  As shown in FIG. 10, in the stop control table setting process, first, it is determined whether or not there is an unstopped reel, that is, whether or not there is a reel for which rotation control has been continued without an effective stop operation. Is determined (Se1). Then, if there is an unstopped reel, the timer interrupt wait process is executed (Se2), the timer interrupt is set to enable, and after waiting until the timer interrupt process (main) is performed once Then, after setting the timer interrupt to be prohibited (Se3), the stop control table setting process is performed for one reel for which the rotation control is continued (Se4), and the number of sliding symbols for each timing at which the stop operation is performed is calculated. An identifiable stop control table is set in a predetermined area of the RAM 41c.

  Then, after the stop control table setting process for one reel is completed, it is determined whether or not the stop control table setting process has been performed for all unstopped reels (Se5), and the stop control table setting process is performed. If there are no unstopped reels, the process returns to the step of Se2, and after executing the timer interruption waiting process, the stop control table is set for the remaining reel in the step of Se4 through the step of Se3. Perform processing to set the stop control table.

  Then, when it is determined that the stop control table has been set for all the unstopped reels at the step Se5, or when it is determined that there are no unstopped reels at the step Se1, the stop control table setting process is performed. End and return to the reel control process.

  Next, a timer interrupt process (main) executed by the main control unit 41 by interrupting the start process and the game process at predetermined intervals will be described with reference to FIG.

  As shown in FIG. 11, in the timer interrupt process (main), first, the timer interrupt is disabled (Sf1), and the register in use is saved in the stack area (Sf2). In addition, other interrupts are automatically prohibited during the execution period of the timer interrupt process (main), and other interrupts are also prohibited by executing the program in step Sf1. Since other interrupts are prohibited twice, it is possible to prevent other interrupts from being executed redundantly during execution of the timer interrupt process (main).

  After the register is saved in step Sf2, a power failure determination process is executed (Sf3). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in the step of Sf3, it is determined whether or not the power interruption flag is set (Sf4). If the power interruption flag is not set, the process proceeds to Sf5, and the power interruption flag is set The power interruption process (main) is executed. In the power interruption process (main), a process for setting destruction diagnosis data (5A (H) in the present embodiment), a process for initializing all output ports, and all storage areas (unused areas and unused areas) of the RAM 41c. The RAM parity adjustment data is calculated and set so that the exclusive OR of the stack area (including the used stack area) becomes 0, and processing for prohibiting access to the RAM 41c is executed. Then, the voltage drops and the main CPU 41a Wait until it stops.

  If it is determined in step Sf4 that the power interruption flag has not been set, port input processing (Sf5) for inputting detection data of various switches from the input port, whether or not the detection state of the switches has changed A switch input determination process (Sf21) for making a determination, a request for transmitting an operation detection command, and the like is executed.

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) from the four types of timer interrupts 1 to 4 is updated to advance by 1 (Sf7). In step Sf7, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process (main) is executed. The value of the branch counter is referred to in each process executed in the timer interrupt process (main). For example, a predetermined control is executed when the branch counter reaches a predetermined value. This control is branched.

  After updating the timer interrupt branching counter in step Sf7, time counter update processing for updating various time counters (Sf8), setting and transmitting a lighting signal for dynamically lighting various indicators such as LEDs LED dynamic display processing (Sf9) for performing the above, external output signal update processing (Sf10) for updating and transmitting the output setting of the external output signal, various commands such as door commands and operation end commands set in the command queue Command transmission processing (Sf11) for performing transmission and the like is sequentially executed.

Thereafter, a reel rotation control process for controlling the rotation of the reels is performed by setting the excitation patterns of the reel motors 32L, 32C, and 32R according to the progress of the game and the like (Sf12). In the reel rotation control process, an address of a specific area of the ROM 41b is designated based on various requests such as an acceleration request set in the reel control process of the main process described above according to the progress of the game. The address of a specific area of the ROM 41b includes an excitation pattern for sequentially exciting the excitation phases (φ1, φ2, φ3, φ4) of the reel motor in accordance with the reel control mode (acceleration, constant speed rotation, stop, etc.). And the update timing of the excitation pattern is stored. Then, when it is specified that the update timing has been reached based on the reel step number counter and the symbol step number counter updated by the reel step number update process described later, the address of the specific area to be designated is stored in the RAM 41c. Set to a predetermined area. An excitation pattern specified from the address specified and set by the reel rotation control process is referred to in motor phase signal output control described later, and a drive signal corresponding to the excitation pattern is supplied to each reel motor 32L, 32C, 32R. By outputting, each reel motor 32L, 32C, 32R is rotated, stopped, etc. in a predetermined control mode. For example, when a stop request is set in a predetermined area of the RAM 41c in the reel rotation stop process described above, the predetermined area in the RAM 41c is referred to based on the setting of the stop request. The number of sliding frames when the reel is stopped is specified, and the number of steps for starting full-phase excitation of the reel motor based on the stop control flag set in the above-described sliding frame number setting process is 12 steps or 13 steps It is specified whether it is. Then, based on the number of sliding symbols, the symbol number of the symbol to be stopped at a predetermined stop position (in this embodiment, the middle position of the reel) is specified, the value of the symbol number counter becomes the symbol number, and the symbol step Start step of predetermined all-phase excitation stop control in which the value of the number counter is specified based on the stop control flag (in this embodiment, when the gaming state is a gaming state other than CT, Steps (13th step) and 17-step symbols are 13 steps (14th step). If the gaming state is CT, whether or not a specific condition can be satisfied for 16-step symbols For the 12-step (13th step) and 17-step symbols, if the specific condition cannot be established, the 13-step (14th step) If the conditions can be satisfied, a 12 step (13 th step).)
Then, the address of a specific area designated in response to the stop request is set in a predetermined area of the RAM 41c. Thereafter, the address is referred to in the motor phase signal output control, and the drive signal corresponding to the excitation pattern specified from the address is output to the corresponding reel motor, so that the reel motor is stopped.

  In the reel rotation control process, a reel step number counter (for each reel 2L, 2C, 2R, which is set in a predetermined area of the RAM 41c) In this embodiment, 0 to 400 steps can be counted, and the counter is set to a value larger than 336 steps required for the reel to make one turn. .), A symbol step counter (a counter that counts symbol steps at the time of the timer interruption at a later-described determination position; 0 to 16 steps for 16 symbols; 0 to 17 steps for 17 symbols; Is set to a value larger than the number of steps per symbol of the reel (16 steps in this embodiment). The symbol number counter (counter that counts the symbol number of the symbol located on the winning line LN at the time of the timer interruption) is updated, and the reel rotation state is constant speed. A reel speed state flag that can specify whether or not is set in a predetermined area of the RAM 41c.

  After the reel rotation control process is executed in step Sf12, a port output process for performing a process such as transmitting a control signal to the solenoid drive circuit 46 (Sf13), in the reel rotation control process in step Sf12 described above A motor phase signal output process for outputting a motor phase signal for exciting each excitation phase of each reel motor to each reel motor 32L, 32C, 32 with the designated excitation pattern is executed (Sf14).

  Thereafter, the register saved in step Sf2 is restored to the state at the start of the timer interrupt process (main) (Sf15), the timer interrupt is set to enable (Sf16), and the timer interrupt process (main ) To return to the main process when the timer interrupt process (main) is started.

  As described above, the main control unit 41 according to the present embodiment performs the timer interrupt process (main) in the reel rotation stop process of the main process when an effective stop switch operation is detected for the reel under rotation control. Based on the reel symbol step counter updated by the reel step number updating process, the symbol number that is the stop operation position is acquired, and the corresponding reel is stopped. When the symbol number that becomes the stop operation position is acquired in the reel rotation stop processing, the value of the symbol step number counter is within the determination range (in this embodiment, in the case of 16 step symbols, 0 to 11 steps, 17 steps). In the case of symbols, 0-12 steps) and not in the non-determined range (in this embodiment, in the case of 16-step symbols, 12-15 steps, in the case of 17-step symbols, 13-16 steps), That is, the symbol number is acquired on condition that the value of the symbol step number counter is not within a predetermined range, that is, if the symbol step number counter value is not within the specific range, the symbol number at that time is On the other hand, if the value of the symbol step number counter is not within a specific range, the symbol step number counter value may be out of the specific range. The waiting, so as to obtain the symbol number when the value of the symbol step counter is out of a specific range.

  The non-determination range, which is the range of the number of symbol steps in which the main control unit 41 does not acquire the symbol number, started the control of all-phase excitation for the corresponding reel when the reel motor was stopped by exciting all the phases. After that, the reel motor of the reel has a width of the number of steps equal to or larger than the number of steps rotated by the inertial force until the rotor stops, and in this embodiment, the non-determination range is defined as 16 step symbols. The symbol step number counter has a range of 4 to 15 steps. In the case of a 17 step symbol, the symbol step number counter has a range of 13 to 16 steps.

  Specifically, as shown in FIG. 12 (a), with the position of the uppermost end of the region corresponding to the middle stage of each reel 2L, 2C, 2R in the see-through window 3 as the determination position, the symbol step for the symbol positioned at the determination position The number is counted by the symbol step number counter, and the symbol number of the symbol located at the judgment position is counted by the symbol number counter, and when the stop switch is operated, the value of the symbol step number counter is in the non-determination range. Is within a specific range (in this embodiment, in the case of a 16-step symbol, 12 to 15 steps, in the case of a 17-step symbol, 12 to 16 steps) and not in the determination range (in this embodiment, the 16-step symbol In the case of 0 to 11 steps in the case of 17 steps and 0 to 12 steps in the case of 17 steps), the value of the symbol number counter at that time is set to the stop operation position. To get as become the symbol number. On the other hand, as shown in FIG. 12B, when the stop switch is operated, the value of the symbol step number counter is within a specific range that is a non-determination range (in this embodiment, in the case of 16 step symbols). In the case of 12 to 15 steps and 17 steps, 13 to 16 steps), the value of the symbol number counter at that time is not acquired as the stop operation position, and the number of symbol steps at the determination position is specified. By waiting until it is out of range (0 to 11 steps in the case of 16 step symbols, 0 to 12 steps in the case of 17 step symbols in this embodiment), and then the reel is further rotated, The symbol that passes the determination position becomes the next symbol, the symbol number counter is updated, and the value of the symbol step number counter is out of a specific range and the value within the determination range (in this embodiment, When a step), to obtain the value of the symbol number counter at that time for the symbol number, to stop operation position.

  As described above, in this embodiment, since the reel motor is rotated by four steps with the inertial force after starting the all-phase excitation stop control, the reel motor is stopped at the determination position (FIGS. 12A and 12B). The value of the symbol step counter for the symbol passing through the reference is within the range from the maximum value of the counter to 4 steps before the maximum value (in the case of 16 step symbols, 12 to 15 steps, 17 step symbols) In the case of step 13 to 16), when starting the all-phase excitation stop control and stopping the reel motor, the value of the symbol number counter when starting the all-phase excitation stop control The symbol specified on the basis of the symbol cannot be stopped at the position of the middle stage of the reel with zero sliding frames. For example, as shown in FIG. 12B, the value of the symbol number counter is 10 which is the symbol number of a 16-step symbol, the value of the symbol step number counter is 12 to 15, and the symbol step at the determination position When the stop operation is performed when the number is the 13th to 16th steps, if the all-phase excitation stop control is started at any timing within the range of the number of symbol steps, the symbol step The reel stops at a position where the value of the number counter reaches 0 or more across 15, that is, a position where at least a part of the symbol area of symbol number 11 straddles the middle area of the reel. The symbol of symbol number 10 specified based on the value of the symbol number counter when performed cannot be stopped at the middle position of the reel. That is, at least one frame is set as the number of sliding frames for the symbol of the symbol number specified based on the value of the symbol number counter when the stop operation is performed, and the symbol of the symbol number next to the symbol number is set to the reel. It will be stopped at the middle position.

  For example, when the stop operation is performed when the value of the symbol number counter is the symbol number of the 17-step symbol and the value of the symbol step number counter is 13 to 16 included in the non-determination range, If all-phase excitation stop control is started at any timing within the range of the number of symbol steps, at least a part of the symbol area of the symbol number next to the symbol number where the stop operation has been performed is reel. As in the case of stopping the 16-step symbol described above, the symbol of the symbol number when the stop operation is performed can be stopped at the middle position of the reel. Since the number of sliding frames is at least one frame, the symbol of the symbol number next to the symbol number is stopped at the middle position of the reel.

  On the other hand, when the value of the symbol step number counter for the symbol passing through the determination position (see FIGS. 12A and 12B) is within the determination range, that is, outside the specific range, the all-phase excitation stop control is started. When the reel motor is to be stopped, the symbol specified based on the value of the symbol number counter when starting the all-phase excitation stop control is stopped at the position of the middle stage of the reel with zero sliding frames. be able to. For example, as shown in FIG. 12 (a), the symbol number of a 16-step symbol is 10, the value of the symbol step number counter is 0 to 11, and the symbol step number at the determination position is 1 to 12. When the stop operation is performed, the value of the symbol step number counter is set to a predetermined all-phase excitation stop control start step after the number of symbol steps in which the stop operation is performed (in this embodiment, 16 steps). 12 steps in the case of step symbols), by starting the all-phase excitation stop control, the symbol number counter value becomes 15, that is, the symbol with symbol number 10 is placed at the middle position of the reel. The reel can be stopped. That is, the symbol of the symbol number specified based on the value of the symbol number counter when the stop operation is performed can be stopped at the middle position of the reel with zero sliding frames. For example, when the stop operation is performed when the value of the symbol number counter is the symbol number of the 17-step symbol and the value of the symbol step number counter is outside the non-determination range, When the value of the symbol step number counter is a predetermined all-phase excitation stop control start step after the number of symbol steps for which stop operation has been performed (in this embodiment, 13 steps in the case of 17 step symbols), By starting the excitation stop control, the reel can be stopped at the position where the value of the symbol step counter becomes 16, that is, the symbol of the symbol number when the stop operation is performed at the middle position of the reel. .

  As described above, the symbol number acquired when the value of the symbol step number counter is within the determination range, that is, outside the specific range, is set as the stop operation position, so that it stops at the middle position of the reel based on the symbol number. When specifying a symbol that can be used, it is possible to stop the symbol number at the middle position of the reel, in which range the symbol step number is obtained, that is, the symbol number is acquired. The symbol number can be used to specify the stop position of the reel without considering whether or not.

  In a conventional slot machine, it is possible to rotate and stop a reel using a stepping motor as a reel motor. The number of symbol steps assigned to each symbol arranged on the reel is counted and the number of symbol steps is counted. The symbol number is updated based on this, and the number of sliding symbols is determined according to the symbol number when the reel is stopped, and the reel cannot be stopped immediately after the stop operation is detected. If the number of symbol steps when the stop operation is detected is within a certain range of steps that cannot be stopped with the symbol, the value obtained by adding 1 to the symbol number when the reel is stopped Is acquired as a symbol number when a stop operation is detected.

  In such a configuration, according to the number of symbol steps when the stop operation is detected, the symbol number needs to be obtained by adding 1 to the symbol number when the stop operation is detected. In order to specify the symbol number at that time, extra processing will be required.

  On the other hand, the slot machine 1 of the present embodiment includes a stepping motor as the reel motors 32L, 32C, and 32R, and is configured to be able to rotate and stop the reels 2L, 2C, and 2R. The main control unit 41 includes a symbol step number counter (or reel step number counter) updated at a predetermined update timing determined according to an excitation pattern for changing the excitation state of the stepping motor, and the symbol step number. A symbol number counter that is updated each time a predetermined number of steps (16 steps and 17 steps in this embodiment) assigned per symbol of the reel by the counter is counted. When a stop operation is performed, the stop operation is performed based on the symbol number acquired from the symbol number counter. A corresponding rotation position is specified, and a reel rotation stop process is executed to stop the corresponding reel at the stop position. In the reel rotation stop process, the value of the symbol step number counter is within a specific range (in this embodiment, In the case of a 16-step symbol, the range is 12 to 15, and in the case of a 17-step symbol, the range is 13 to 16. When the symbol is out of a specific range without acquiring the symbol number (this embodiment) Then, when the value becomes 0), the value of the symbol number counter is acquired as the symbol number. Therefore, an extra process for specifying the symbol number according to the number of symbol steps when the reel is stopped, for example, When the value of the symbol step number counter is in a specific range, the symbol number counter value can be obtained in a simple procedure without performing a process such as obtaining a value obtained by adding 1 to the symbol number counter value as a symbol number. It is possible to get.

  In the present embodiment, the reel motors 32L, 32C, and 32R are used to rotate the reels 2L, 2C, and 2R having a plurality of symbols arranged on the outer peripheral surface, whereby a plurality of symbols that can be visually recognized by the player are obtained. Although it is a configuration that can display a variation display to move, means for performing a variation display to move a plurality of symbols may be other than the reel, for example, a belt having a plurality of symbols arranged on the outer peripheral surface The structure etc. which can perform a fluctuation | variation display by making it move may be sufficient.

  In the present embodiment, the main control unit 41 executes an update process such as the number of reel steps at every predetermined update timing determined according to the excitation pattern for changing the excitation state of the stepping motor, The step number counter is updated, and the symbol number counter is updated every time a predetermined number of steps (16 steps and 17 steps in this embodiment) allocated per symbol of the reel is counted. Reel step number counter for counting the number of steps from the reel reference position, which is updated at a predetermined update timing determined according to the excitation pattern for changing the excitation state of the stepping motor. Thus, a predetermined number of steps allocated per symbol of the reel (in this embodiment, 16 steps). , 17 steps) may be configured to update the symbol number counter each time it is counted.

  Also, in this embodiment, the design judgment range to which 16 steps are assigned and the design judgment range to which 17 steps are assigned are different ranges depending on the number of steps assigned to the design. There may be a configuration in which the determination range is a common range for the symbols to which 16 steps are assigned and the symbols to which 17 steps are assigned. In such a configuration, as a common determination range, the narrower one of the determination range of the 16-step symbol and the determination range of the 17-step symbol is applied, so that the stop control of either the 16-step symbol or the 17-step symbol is performed. However, the symbol number can be acquired by a simple procedure, and the symbol with the corresponding symbol number can be stopped on the reel.

  In the reel rotation stop process, the main control unit 41 according to the present embodiment has a value of the symbol step counter within a specific range (in this embodiment, within the range of 12 to 15 in the case of 16 steps, 17 steps In the case of the range of 13 to 16), the symbol number is not obtained from the symbol number counter. The specific range is when the value of the symbol step number counter is within the range. Since the symbol with the symbol number specified based on the symbol number counter cannot be stopped at the predetermined stop position, the symbol number acquired in the reel rotation stop process is used when the stop operation is performed. Thus, since the symbol specified by the symbol number cannot be stopped at the stop position, it is not necessary to perform the process of correcting the acquired symbol number.

  In the present embodiment, the main control unit 41 determines that the value of the symbol step counter is in a specific range (in the present embodiment, in the range of 12 to 15 in the case of 16 steps, 17 steps in the reel rotation stop process). In the case of symbols, the range of 13 to 16), the symbol number is not acquired, and when the symbol number is out of a specific range (in this embodiment, it is 0), the symbol number counter value is The main control unit 41 is configured to acquire the value of the symbol number counter as the symbol number when the value of the symbol step number counter is at least outside a specific range in the reel rotation stop process. If the value of the symbol step number counter becomes a specific value out of the specific range (for example, 11 out of 0 to 11), the value of the symbol number counter is displayed. It may be configured to acquire as a number. In such a configuration, when the symbol number is acquired in accordance with the stop operation, the symbol number counter value is acquired as the symbol number when the symbol step number is a specific value. Extra processing for specifying the symbol number according to the number of symbol steps, for example, processing for obtaining a value obtained by adding 1 to the symbol number counter as the symbol number when the value of the symbol step counter is within a predetermined range The symbol number can be acquired by a simple procedure without performing the above.

  Further, in such a configuration, the specific value out of the range where the symbol step number counter is outside the specific range is the symbol number specified from the current symbol number counter when the symbol step number counter is updated next time. The number of symbol steps at which the reel cannot be stopped in the symbol area, that is, a value within the range of symbol step numbers at which the symbol with the symbol number specified based on the symbol number counter can be stopped at a predetermined stop position. When the value of the symbol step number counter becomes the specific value one step before being updated from the outside of the specific range to the value within the specific range. Since the symbol number is obtained from the counter, the symbol number is not obtained from the symbol number counter at that time when the value of the symbol step counter is outside one specific range. , It does not wait until the symbol step number counter is out of the next specified range to acquire the next symbol number, and prevents the timing of the stop operation and the area of the symbol to be stopped from deviating greatly. it can.

  The main control unit 41 of this embodiment is configured to identify a symbol number based on a symbol step number counter when a reel is operated to be stopped, and is updated by a reel step number update process in the reel rotation control process. When it is determined whether a drive signal for stopping the reel is to be output based on the symbol step counter, and based on the symbol step counter, it is determined that the reel motor excitation pattern update timing has come Since the drive signal for stopping the reel on which the stop operation has been performed is output, whether or not the drive signal for stopping the reel motor is output even when the symbol number is specified when the stop operation is performed Also in the case of determination, since the number of symbol steps updated by the update process such as the common number of reel steps is used, the step used for the process It is possible to reduce the processing and area for storing the number of the steps to update the.

  In the present embodiment, the main control unit 41 is configured to identify a symbol number based on the symbol step number counter and determine whether to output a reel motor drive signal based on the symbol step number counter. The symbol number may be specified based on the reel step number counter updated by the reel step number updating process, and it may be determined whether to output a reel motor drive signal. Even in such a configuration, similarly to the configuration of the present embodiment, even when the symbol number is specified when the stop operation is performed, it is determined whether or not to output a drive signal for stopping the reel motor. Even in this case, by using the number of reel steps updated by the update processing such as the common number of reel steps, the processing for updating the number of steps used for the processing and the area for storing the number of steps can be reduced.

  The main control unit 41 according to the present embodiment includes reel sensors 33L, 33C, and 33R that detect the reel reference position for each of the reels 2L, 2C, and 2R. Since the symbol step number counter is set to the initial value in response to detection of the reel reference position by 33L, 33C, and 33R, the actual position of the reels 2L, 2C, and 2R and the number of steps of the reel are updated. The value of the symbol step number counter can be matched.

  In the present embodiment, the main control unit 41 sets the reel step number counter to an initial value in response to the reel reference position being detected by the reel sensors 33L, 33C, and 33R in the reel step number updating process. Therefore, the actual position of the reels 2L, 2C, and 2R can be matched with the value of the reel step number counter updated by the updating process such as the number of reel steps.

  The main control unit 41 according to the present embodiment determines whether or not an input / output error, a change in the output state of the door opening detection switch 25, and a reel rotation error have occurred as specific events that may have occurred. Error check processing, door opening check processing, and rotation error check processing can be executed. In the reel control processing, at least after the effective operation of the stop switches 8L, 8C, and 8R is detected, the symbol number in the reel rotation stop processing is detected. Since it is not determined whether or not a specific event has occurred in the period until the counter value is acquired, the processing load until the symbol number counter value is acquired after the stop operation can be reduced. it can.

  In this embodiment, the number of symbols arranged on one reel is 20 symbols, and the reel motor requires 336 steps to make one round, and 16 steps or 17 steps per symbol for all 20 symbols on one reel. By assigning, it is possible to make one cycle of 20 symbols when the reel makes one turn. Since the reel motor is rotated by four steps with the inertial force after the all-phase excitation stop control is started and stopped, the game state is set to stop the predetermined number of steps of the reel motor at a predetermined position. When the gaming state is other than CT, the all-phase excitation stop control is started four steps before the last step number among the number of symbol steps assigned to the symbol.

  In this way, in a configuration in which one cycle of 20 symbols can be performed when the reel makes one turn, as in this embodiment, the main control unit 41 performs an effective reel stop operation. When the reel rotation stop process is executed and the value of the symbol step number counter is within a specific range (non-determination range), the symbol number is not acquired and when the value is outside the specific range (determination range) In the configuration in which the value of the number counter is acquired as the symbol number, for one symbol of the symbols having different number of steps assigned to one symbol, the value of the symbol step number counter corresponds to the symbol corresponding to the symbol. When it is within one specific range (first non-determination range), the symbol number counter is not acquired, and when it is outside the first specific range (first determination range), the value of the symbol number counter is Get as a symbol number On the other hand, for other symbols having different numbers of steps assigned to one symbol, the value of the symbol step number counter is set to a second specific range (a value obtained by correcting the first specific range by an operation such as addition or subtraction ( When it is the second non-determination range), the symbol number is not acquired, and when it is outside the second specific range (second non-determination range), the value of the symbol number counter is acquired as the symbol number. With the configuration, even if the symbol number counter value when the stop operation is performed is the symbol number corresponding to the first specific range, the symbol number corresponding to the second specific range is not. However, the value of the symbol number counter can be acquired when the value of the symbol step number counter is outside the common specific range (specific range consisting of the common step number).

  Specifically, for example, as shown in FIG. 13 (a), a 20-design reel that cannot equally divide the number of steps required to make one revolution of the reel, and a design to which 16 steps are assigned, In the configuration in which the symbols to which the steps are assigned are arranged, the symbols to which the 16 steps are assigned are, as in the present embodiment (see FIG. 9), the first specific range (12 ~ 15) as the non-determination range and outside the first specific range (0-11) as the determination range, for symbols assigned with 18 steps, the first specific range (12-15) ) By adding 2 steps (difference between 16 steps and 18 steps) and correcting the second specific range (14-17) as a non-determination range, and out of the second specific range (0-13) ) Judgment range With this configuration, the symbol number counter value is common within a specific range (stop operation) regardless of whether the symbol is assigned with 16 steps or the symbol is assigned with 18 steps. The value of the symbol number counter can be acquired when it is outside of a specific range of four steps in which the reel cannot be stopped at the symbol corresponding to the symbol number counter value when

  Further, as shown in FIG. 13 (b), for example, in a configuration in which a reel of 20 symbols and a symbol to which 16 steps are allocated and a symbol to which 18 steps are allocated are arranged, 18 steps are allocated. For the symbols to which 16 steps are assigned while the third specific range (14 to 17) is set as the non-determination range and the outside of the third specific range (0 to 13) is set as the determination range. The fourth specific range (12 to 15) corrected by subtracting the difference between the 16th step and the 18th step from the third specific range is set as a non-determination range, and outside the fourth specific range (0 ˜13) is also used as the determination range, and in the same manner as in the above-described example, a specific range in which the value of the symbol number counter is the same for all symbols (the symbol number when the stop operation is performed). Cow It is possible to obtain the value of the symbol number counter when is other than a specific range) of four steps that can not be stopped reel symbols corresponding to the value of the data.

  In the above-described example, a specific range (a symbol number counter when the stop operation is performed) of one of the symbols to which 16 steps are assigned as the number of symbol steps or the symbols to which 18 steps are assigned. (A specific range consisting of 4 steps in which the reel cannot be stopped with a symbol corresponding to the value of 1) is added or subtracted to make a specific range for the other symbol. A configuration in which a specific range for a symbol with a smaller number of symbol steps assigned to is applied as a specific range for another symbol without correction, for example, even with a 16-step symbol, Even in the case of a step pattern, a specific range (12 to 15 or 12 to 170) with 11 as a specific step common to both, Outside the range of (0 to 11) may be configured to set. In such a configuration, for a symbol assigned 16 steps as a symbol step number and a symbol assigned 18 steps, the value of the symbol step number counter is outside a common specific range (0 to 11). Stop control for acquiring the symbol number value and stopping the reel can be performed by a common process. The common specific step is a step in which the symbol can be stopped at a predetermined position when the number of sliding symbols is 0 in any symbol having a different number of steps assigned to one symbol. Is the last value of the symbol determination range (steps before the subsequent four steps) having the smallest number of steps assigned to.

  As described above, for a symbol having a number of symbols in which the number of steps required to make one reel make one turn cannot be divided evenly and having a different number of steps assigned to one symbol, When the value of the number counter is the first specific range (first non-determination range) corresponding to the symbol, the symbol number is not acquired and is outside the first specific range (first determination range). The symbol number counter value is acquired as the symbol number when the symbol number is reached, while the symbol number counter value is the first specific range for other symbols with different number of steps assigned to one symbol. If it is the second specific range (second non-determination range) corrected by adding or subtracting or the like, the symbol number is not acquired and it is outside the second specific range (second non-determination range). When the symbol number Is a structure to obtain the value of the pointer for the symbol number, the value of the symbol number of steps the counter, based on whether a specific value, may be to obtain the symbol number, or do not get configured.

  As such a configuration, for example, for one symbol (for example, a symbol to which 16 steps are allocated) of symbols having different number of steps allocated to one symbol, the value of the symbol step number counter is Is a first specific value (first determination value, for example, 11 steps), the value of the symbol step number counter is acquired as a symbol number, and a value other than the first specific value (for example, 0 to 10 steps and 12 to 15 steps), the symbol number counter value at that time is not acquired, and the symbol number counter value is acquired as the symbol number when the first specific value is reached thereafter. On the other hand, for other symbols (for example, symbols to which 18 steps are allocated) among symbols having different numbers of steps allocated to one symbol, the number of symbol steps is not counted. Is the second specific value corrected by adding or subtracting the first specific value (for example, 13 steps obtained by adding two steps of the difference between 16 steps and 18 steps) The value of the symbol step number counter is acquired as a symbol number, and when the value is a value other than the second specific value (for example, 0 to 12 steps and 14 to 17 steps), the symbol counter value at that time is not acquired. In addition, when it becomes the second specific value after that, it may be configured to acquire the value of the symbol number counter as the symbol number, and with such a configuration, when the stop operation is performed Whether the symbol number counter value is the symbol number corresponding to the first specific value or the symbol number corresponding to the second specific value, the symbol number counter value is commonly specified Range (at that time When the symbol specified based on the value of the symbol number counter at is immediately before the last four steps of the symbol step number), the symbol number 0 cannot be stopped at the predetermined position with the number of sliding frames. The value of the counter can be acquired.

  In addition, for example, for any symbol having a different number of steps allocated to one symbol, the symbol can be stopped at a predetermined position with the number of sliding symbols 0, and the step allocated to one symbol The last value (0 to 11 steps in a design to which 16 steps are assigned in a configuration including a design to which 18 steps are assigned and a design to which 16 steps are assigned in the design determination range of the symbol having the smallest number ( For example, 11 steps) is a common specific value, and when the common specific value is the common specific value, the value of the symbol step number counter is acquired as the symbol number, and when it is a value other than the common specific value, The symbol number counter value is not acquired and the symbol number counter value is used as the symbol number. It is possible to obtain a configuration, and with such a configuration, a symbol number counter when a common determination range stop operation is performed for any symbol with a different number of steps assigned to one symbol. When the value of is a common specific value, the value of the symbol number counter can be acquired.

  Next, the specific reel stop control performed by the main control unit 41 when the gaming state is CT will be described with reference to FIGS.

  In a conventional slot machine, the number of symbols arranged on one reel is generally 21 symbols, and a stepping motor for 21 symbols that requires 336 steps to complete a round, that is, a multiple of 21 symbols, rotates the reel. It is used as a reel motor, and by assigning 16 steps per symbol evenly to all 21 symbols of one reel, it is possible to make a round of 21 symbols when the reel makes one turn. Yes. On the other hand, in the slot machine 1 of this embodiment, a reel motor that makes one round in 336 steps used in the conventional slot machine in which 21 symbols are arranged on one reel is used, and each reel 2L, 2C, 2R is used. In the configuration, 20 symbols are arranged per reel. In such a configuration, the number of steps of the reel motor cannot be assigned equally per symbol for all 20 symbols of one reel, and there is one symbol with a different number of steps allocated per symbol. In this embodiment, a symbol to which 16 steps are allocated (hereinafter referred to as 16 step symbols) and a symbol to which 17 steps are allocated (hereinafter referred to as 17 step symbols) are mixed. . In the present embodiment, the 16-step symbol and the 17-step symbol are mixed, but the symbol to which a different number of steps (for example, 18 steps, 19 steps, etc.) other than these steps is allocated is mixed. There may be.

  In this embodiment, as described above, when the gaming state is CT, the maximum delay time from the timing at which the stop switch is operated to the timing at which stop control of the reel is performed for a predetermined specific reel. The time is shortened and limited to a prescribed time (75 milliseconds in this embodiment).

  For example, as shown in FIG. 14A, in a specific reel in which the gaming state is CT and the maximum delay time is limited to a specified time, a symbol (19) that is a 17-step symbol, a symbol (0) that is a 16-step symbol (0) ), The 17-step symbol (1) is continuously arranged, and in the above-described reel stop control process, the symbol number of the symbol (0) is acquired based on the symbol number counter. When stopping the reel at the timing at which the 13th step (14th step) of the lowermost symbol (19) is positioned at the reference position, when the number of sliding frames is stopped, The main control unit 41 starts the all-phase excitation stop control in 12 steps (13th step) of the symbol (1), and as shown in FIG. Step th) That the upper end, and stops controlling the reel so as to stop so as to be located at the reference position (hereinafter sometimes referred to a stop control to stop the number of sliding symbols as 1 frame and stop control 1).

  At this time, the reel is moved over a total of 33 steps from 13 steps of symbol (19) to 12 steps of symbol (1) from when the stop operation is performed to when all-phase excitation stop control is performed. The Since a reel rotated at a constant speed requires about 2.24 milliseconds to move per step, it takes about 73.9 milliseconds to move 33 steps.

  On the other hand, for example, as shown in FIG. 15 (a), a 16-step symbol (0), a 17-step symbol (1), and a symbol (2) are continuously arranged in one reel. In the reel stop control process described above, the 12th step (13th step) of the symbol (0), which is the lowest end of the range of the number of steps in which the symbol number of the symbol (1) is acquired based on the symbol number counter, is the reference position. In the case of performing stop control 1 in which the number of sliding frames is one frame when the reel is operated at the timing positioned at, the main control unit 41 performs 12 steps (13) of the symbol (2). In step (5), all-phase excitation stop control is started, and as shown in FIG. 15 (b), 15th step (16th step) of symbol (2), that is, the upper end is stopped so as to be positioned at the reference position. To To stop control Le.

  At this time, the reel is moved over a total of 34 steps from 13 steps of symbol (0) to 12 steps of symbol (2) from when the stop operation is performed to when all-phase excitation stop control is performed. , It takes about 76.2 milliseconds to move 34 steps.

  As described above, in the reel stop control, when pulling in and stopping by one-frame sliding, when the 16-step symbol and the 17-step symbol are included in the pull-in range, that is, the number of steps in the pull-in range is 33 steps or less. In some cases, the delay time from the timing when the stop switch is operated to the timing when the reel stop control is performed is about 73.9 milliseconds, and the gaming state is CT, so that the reel from the timing when the stop switch is operated. Even when the maximum delay time until the timing for performing the stop control is limited to a specified time (75 milliseconds in this embodiment), the reel can be stopped by pulling in one frame slip. On the other hand, when pulling in one frame slip and stopping, if two 17-step symbols are included in the pull-in range, that is, if the number of steps in the pull-in range exceeds 33 steps, the stop switch was operated. The delay time from the timing to the timing to perform the reel stop control is about 76.2 milliseconds or more, and the maximum delay from the timing at which the stop switch is operated to the timing to perform the reel stop control because the gaming state is CT When the time is limited to a specified time (75 milliseconds in this embodiment), the reel cannot be stopped by pulling in one frame slip.

  On the other hand, when the gaming state is CT, the main control unit 41 according to the present embodiment is configured to stop the 17-step symbol at the reference position with the number of sliding symbols as one frame in the specific reel stop control. Is the 13th step of the 17-step symbol, that is, the all-phase excitation stop control 1 that starts the all-phase excitation stop control 5 steps before the end of the symbol, or the 14th step of the 17-step symbol, that is, 4 steps before the end of the symbol. All-phase excitation stop control 2 for starting all-phase excitation can be selected and performed.

  For example, as shown in FIG. 16 (a), when the gaming state is CT, the symbol is a 17-step symbol on a specific reel whose maximum delay time is limited to a specified time (75 milliseconds in this embodiment). (1), symbol (2), symbol (3) are arranged in succession, and in the reel stop control process described above, the number of steps in which the symbol number of symbol (2) is acquired based on the symbol number counter In the case where the stop operation of the reel is performed at the timing when the 13th step (14th step) of the symbol (1), which is the lowest end of the range, is positioned at the reference position, and stop control is performed so that the number of sliding frames is one frame. If the gaming state is CT, all phases are displayed in 12 steps (13th step) of the symbol (3) based on the fact that the stop control flag A is set in the above-described sliding piece number setting process. excitation Performing all phase excitation stop control 1 to start.

  As shown in FIG. 16B, when the all-phase excitation stop control 1 is performed based on the stop control flag A, the 13th step (14th step) of the symbol (1) is positioned at the reference position. In the period from when the stop operation is performed until the design is slid by one frame until the all-phase excitation stop control 1 is performed in the 12 steps (13th step) of the design (3), the reel Will move 33 steps over about 73.9 mm. Then, by moving 4 steps after the start of all-phase excitation stop control 1 and stopping, 15 steps one step before the last step of symbol (3) are stopped at the reference position.

  On the other hand, when the gaming state is a gaming state other than CT, the 13th step (14th step) of the symbol (3) based on the fact that the stop control flag B is set in the above-described sliding piece number setting process. Perform all-phase excitation stop control 2 to start all-phase excitation.

  As shown in FIG. 16C, when the all-phase excitation stop control 2 is performed based on the stop control flag B, the 13th step (14th step) of the symbol (1) is positioned at the reference position. After the stop operation is performed, the design is slid by one frame, and then during the 13-step (14th step) of the design (3) until the all-phase excitation stop control 2 is performed, The reel will move 34 steps over approximately 76.2 mm. Then, after the all-phase excitation stop control 2 is started, it is moved and stopped by 4 steps, so that the last step of the symbol (3), that is, 16 steps stops at the reference position.

  Thus, in the reel stop control of a specific reel when the gaming state is CT, the delay time from the timing at which the reel stop operation is performed until the all-phase excitation is performed is a specified time (75 in this embodiment). When a specific condition exceeding (milliseconds) is satisfied, the all-phase excitation stop control 1 for starting all-phase excitation from the 12th step (13th step) is performed, that is, the gaming state is a gaming state other than CT. A delay from the timing when the stop operation is performed until the all-phase excitation is performed by starting the all-phase excitation one step earlier than the all-phase excitation start step performed in the reel stop control of a specific reel in a certain case. The reel stop control is performed within a specified time (75 milliseconds in this embodiment).

  Further, when the gaming state is CT, all-phase excitation stop control 1 is performed on the specific reel, and all steps from a step earlier than the starting step of all-phase excitation in a gaming state other than CT are performed. By starting phase excitation, the position one step before the position where the game state is stopped when the game state is a game state other than CT is stopped at the reference position, and the stop position of the symbol on the specific reel and the specific reel A deviation of one step may occur between the stop positions of symbols on the other reels.

  When the gaming state is a gaming state other than CT, the maximum delay time from the timing when the stop switch is operated to the timing when the reel stop control is performed is not shortened, and the timing when the stop switch is operated Therefore, it is sufficient to stop all phases from the timing when the stop operation is performed by performing all-phase excitation stop control 2 that starts all-phase excitation from the 13th step (14th step). The reel stop control is performed by setting the delay time until the start to within a specified time (in this embodiment, 75 milliseconds).

  As shown in FIG. 17, 20 symbols of symbol numbers 0 to 19 are arranged on a specific reel in which the maximum delay time is limited to a specified time when the gaming state is CT in the slot machine 1 of the present embodiment. 16 symbols out of 336 steps of the reel motor are assigned to the symbols of symbol numbers 0, 5, 10, and 15, and symbols 1 to 4, 6 to 9, 11 to 14, and 16 to 19 are assigned. Each symbol is assigned 17 steps. As described above, in a reel in which a 16-step symbol and a 17-step symbol are mixed, the positions on the reel from which the symbol numbers 0, 4, 5, 9, 10, 14, 15, 19 are acquired in the reel stop control process described above. Is a position (“OK” position in FIG. 17) where the reel can be stopped by sliding one frame within a specified time (75 milliseconds) even if all-phase excitation stop control 2 is performed. The positions on the reels from which numbers 1 to 3, 6 to 8, 11 to 13, and 16 to 18 are acquired are shown in a single frame slip within a specified time (75 milliseconds) when all-phase excitation stop control 2 is performed. This is a position that cannot be stopped (position “NG” in FIG. 17).

  In contrast, in the present embodiment, in the CT stop control table, the reel can be stopped by sliding one frame within a specified time (75 milliseconds) by performing all-phase excitation stop control 2 ( 17 is set to perform all-phase excitation stop control 2. When all-phase excitation stop control 2 is performed, the reel can be slipped by one frame within a specified time (75 milliseconds). It is set to perform the all-phase excitation stop control 1 at a position where it cannot be stopped (a position “NG” in FIG. 17). Thus, in the above-described slip frame number setting process in the reel stop control, all-phase excitation is performed according to the symbol number of the symbol to be stopped at the reference position by one frame slip by referring to the CT stop control table. Either stop control 1 or all-phase excitation stop control 2 can be specified. In the reel stop control when the gaming state is CT, the all-phase excitation stop control 1 or the all-phase excitation stop control 2 is performed according to the symbol number of the symbol to be stopped at the reference position based on the CT stop control table. The reel stop control is selected and the symbol is controlled. Even when the symbol of any symbol number is stopped by sliding one frame, within the specified time (75 milliseconds in this embodiment) from the timing when the stop switch is operated. The reel can be stopped.

  Next, an example of symbol arrangement on a specific reel whose maximum delay time is limited to a specified time when the gaming state is CT will be described with reference to FIGS.

  As shown in FIG. 18, for example, when the left reel is applied as a specific reel, the all-phase excitation stop control 2 is performed when the symbol number is 2, 7, 12, 17 or the game state is CT. By placing the “bell” symbol two positions above the symbol position to be performed, within the range of slipping up to one frame, regardless of when the specific reel is stopped at any timing in the game The “bell” symbol can be stopped at a position on the winning line, that is, in the middle of the reel. Then, as shown in FIG. 19 (a), when the “bell” symbol is stopped at the middle stage of the reel by sliding one frame, the “bell” symbol is applied by applying the all-phase excitation stop control 2. Since all-phase excitation is started at a step four steps before the end of the signal and stopped at four steps, the terminal of the “bell” symbol can be stopped at the same reference position as the reel.

  As a result, for example, in a configuration in which a winning combination of a small role accompanied by paying out medals occurs when the symbol combination of “Bell-Bell-Bell” stops on the winning line LN, it is specified when the gaming state is CT. Even when the “Bell” symbol is stopped on the winning line by sliding one frame on the reel, the “Bell” symbol can be stopped by aligning the end of the “Bell” symbol with the reference position of the reel. The stop position of the “bell” symbol stopped on the LN and the stop position of the “bell” symbol stopped on the winning line in the middle reel and the right reel other than the specific reel are shifted by one step. You can avoid that.

  Also, as shown in FIG. 18, for example, when the left reel is applied as a specific reel, all-phase excitation stop control is performed when the symbol number is 4, 9, 14, 19 or the gaming state is CT. By placing the “cherry” symbol two positions above the symbol position where 1 is performed, when a stop operation is performed at a position two frames before the “cherry” symbol, The symbol “cherry” can be stopped on the winning line LN. Then, as shown in FIG. 19B, when stopping the “cherry” symbol on the winning line LN by one-frame sliding, all-phase excitation stop control 1 is applied, so that “cherry” Since all-phase excitation is performed at a step five steps before the end of the symbol, the step “step” one step before the end of the symbol “cherry” is stopped at the reference position of the reel.

  In this way, by applying the all-phase excitation stop control 1 to a specific reel, the specific symbol that is stopped on the winning line by one frame slip is set to the reel reference position at a step one step before the end. In the configuration to be stopped, when the specific symbol to which the all-phase excitation stop control 1 is applied and stopped on the winning line is included as a constituent symbol of the winning combination symbol combination, the winning combination symbol combination is selected. The same symbol is not aligned on the winning line, and a combination of symbols in which a winning occurs, for example, “Cherry-any-any” (any indicates that any symbol may be used) on the winning line on a specific reel. Stopping all-phase excitation in a specific reel by making the symbols stopped on the winning line in the reels other than the specific reel different from the symbols Recognizing the deviation between the stop position of the symbol on the specific reel and the stop position of the symbols on the reels other than the specific reel, which is caused when all phases are excited in the step 5 steps before the end of the symbol when the control 1 is applied It can be difficult.

  In addition, as shown in FIG. 20, for example, as symbols arranged on the reels 2L, 2C, 2R, an area per symbol on the reel (in this embodiment, an area for 16 steps, an area for 17 steps). The first symbol and the second symbol (for example, the symbol “7” in FIG. 20 and the symbol “Replay” occupying a region smaller than the symbol “7”), which have different symbol areas, In the configuration including the first combination in which a winning occurs when the symbols are aligned on the winning line and the second combination in which a winning occurs when the second symbols are aligned on the winning line, the first reel Among the symbols and the second symbol occupying an area smaller than the first symbol, the first symbol is two positions above the symbol position where the all-phase excitation stop control 2 is performed when the gaming state is CT. Place in the position, the second symbol, the game state In the case of CT, all-phase excitation stop control 1 is arranged at a position two above the position of the symbol where the first-phase excitation stop control 1 is performed. Control 2 is applied and the end of the first symbol is stopped at the reel reference position. When the second symbol is stopped on the reel by one command slip, all-phase excitation stop control 1 is applied. Thus, the step immediately before the end of the second symbol is stopped at the reference position of the reel.

  Thus, when stopping the first symbol, all-phase excitation stop control 2 is applied, while when stopping the second symbol that occupies a smaller area than the first symbol, By arranging the first symbol and the second symbol on the specific reel so that the phase excitation stop control 1 is applied, the all-phase excitation stop control 1 is applied and stopped on the reel as described above. When the step immediately before the end of the symbol is stopped at the reference position of the reel, there is a deviation between the symbol stop position on the reel and the symbol stop position on another reel. Since the second symbol region to which the all-phase excitation stop control 1 is applied is smaller than the first symbol region, the shift of the stop position that occurs in the second symbol is assumed to be entirely in the first symbol. Stop position generated by applying phase excitation stop control 1 It was difficult relative recognized compared to Les.

  Further, as shown in FIG. 21, for example, in a configuration in which a winning can be recognized by aligning a predetermined symbol (a symbol of “Bell” in FIG. 21) on the predetermined line on the winning line, the predetermined line is: In a configuration that is set to a line other than the line that straddles the upper stage of each reel, the line that straddles the middle stage of each reel, and the line that straddles the lower stage of each reel, a predetermined symbol is set to 1 for a specific reel. When stopping the reel by command slip, all-phase excitation stop control 1 may be applied, and the step immediately before the end of the predetermined symbol may be stopped at the reference position of the reel.

  For example, as shown in FIG. 21 (a), the winning combination is recognized when the symbol combination “Bell-Bell-Bell” stops on the V-shaped line extending over the upper stage of the left reel, the middle stage of the middle reel, and the upper stage of the right reel. In this configuration, for example, when the “bell” symbol is stopped on the reel by one command slide with the right reel as the CT control reel, the all-phase excitation stop control 1 is applied and stopped. There is a discrepancy between the stop position of the “bell” symbol on the reel and the stop position of the symbol on the other reels. This deviation width is determined by the stop position of the “bell” symbol on the V-shaped line in the adjacent reel. All-phase excitation stop control 1 is applied to the CT control target reel because it is smaller than the deviation width of the middle stage of the reel and the upper stage of the reel that is the stop position of the “bell” symbol of the specific reel. Stop position caused by Shift can be to difficult to recognize the of.

  Also, as shown in FIG. 21 (a), the winning combination is recognized when the symbol combination “Bell-Bell-Bell” stops at the lower right line across the upper stage of the left reel, the middle stage of the middle reel, and the lower stage of the right reel. In the configuration, the winning combination is recognized by stopping the “Bell-Bell-Bell” symbol combination on the V-shaped line, for example, the “Bell” symbol with the right reel as the specific reel, for example. When the reel is stopped by one command slip, all-phase excitation stop control 1 is applied and stopped, so that the stop position of the “bell” symbol on the reel and the stop position of the symbol on the other reel The width of this shift is that the stop position of the “bell” symbol on the right-down line in the adjacent reel is the middle stage of the reel, and the reel that is the stop position of the “bell” symbol of the specific reel Deviation of being in the lower row Is smaller than the can hardly recognize the deviation of the stopping position caused by being applied the full phase excitation stop control 1 in a particular reel.

  It should be noted that the predetermined line is set to a predetermined line other than the line over the top of each reel, the line over the middle of each reel, and the line over the bottom of each reel. In the configuration in which a winning can be recognized by stopping the predetermined symbols of the same type all together, the above-described example can be applied to the configuration in which the all-phase excitation stop control 1 is applied in the stop control of the predetermined symbol stopped on the predetermined line. Has the same effect as.

  Conventional slot machines generally have 21 symbols arranged on a reel, and a stepping motor that makes one turn at a multiple of 21 so that the number of steps required to move one symbol is equal. Is used.

  In recent years, slot machines with 20 reel symbols have been developed, and when a slotting machine with 20 symbols is used with a stepping motor that makes one round with a multiple of 21 steps, Two or more steps (for example, 16 steps and 17 steps) required to move are required. As a result, depending on the position where the stop operation was performed, even if the number of symbols moving from the stop operation until the target symbol stops is the same, the time from when the stop operation is performed until the target symbol stops As a result, there is a problem that the reels cannot be stopped within a specified time after the stop operation is performed at some positions.

  On the other hand, the slot machine 1 of the embodiment includes reels 2L, 2C, and 2R on which a plurality of types of symbols that can be identified are arranged, and the main control unit 41 uses the reels 2L, 2C, and 2R as reel motors. 32L, 32C, and 32R are moved, and the stop switches 8L, 8C, and 8R are operated to stop the reel, and the symbols move as a plurality of types of symbols arranged on the reel. A 16-step symbol, which is a first symbol assigned with 16 steps, which is the first step number, and a second step in which the number of steps required for the symbol to move is greater than the first step number. 17 steps, which is the second symbol assigned 17 steps, which is the number of steps, and the main control unit 41 has a gaming state of CT. In particular, in the stop control of a specific reel, the range from when the stop switch is operated until the number of sliding frames is set to one frame and stopping the reel includes 17 step symbols. As a result, the reel stops after the stop operation is performed. The stop switch is operated by performing different reel stop control depending on whether or not the specific condition that the predetermined time (75 milliseconds in the present embodiment) exceeds a predetermined time (in this embodiment) is satisfied. Since the specific reel is stopped within a specified time after the operation, the time from when the stop switch is operated until the reel stops can be prevented from exceeding the specified time.

  The specific condition is that the reel is stopped after the stop switch is operated as a result of the second symbol being included in the range from when the stop switch is operated until the reel is stopped by a one-frame slip as a specific fluctuation amount. It is a condition that the time until the start time exceeds a specified time (75 milliseconds in this embodiment), and is within a range from when the stop switch is operated to when the reel stops with one frame slip as a specific fluctuation amount. Even if the second symbol is included, the specific condition is not satisfied if the time from when the stop switch is operated until the reel stops at a specific fluctuation amount does not exceed the specified time.

  In addition, the main control unit 41 of the present embodiment has a specific gaming state in which the maximum delay time from when the stop switch is operated until the reel is stopped is limited to a specified time (in this embodiment, 75 milliseconds). If the gaming state is CT, the reel stop control is different depending on whether or not the specific condition is satisfied. However, in other cases than the specific gaming state, Different reel stop control may be performed depending on whether the specific condition is satisfied or not.

  The main control unit 41 according to the present embodiment includes a 17 step symbol in the range from the time when the stop switch is operated until the number of sliding frames is set to 1 frame in the stop control of the specific reel. If the specific condition that the predetermined time (in this embodiment, 75 milliseconds) exceeds the predetermined time from when the reel is stopped is not satisfied, the number of sliding frames is set as one frame. While stopping the reel, while performing the all-phase excitation stop control 1 for outputting the control signal of the reel motor so as to start the all-phase excitation from the step four steps before the end of the symbol to be stopped at the predetermined reference position. If the specific condition is satisfied, is the step 5 steps before the end of the symbol that is the step before the game state is a game state other than CT? By performing all-phase excitation stop control 2 for outputting a reel motor control signal so as to start all-phase excitation, the time from when the stop switch is operated until the specific reel is stopped exceeds the specified time. Can be prevented.

  In the present embodiment, the main control unit 41 is configured to perform reel stop control that differs depending on whether or not the specific condition is satisfied in the specific reel stop control when the gaming state is CT. When the specific condition is not satisfied, all-phase excitation stop control 1 is applied to stop the specific reel, while when the specific condition is satisfied, all-phase excitation stop control 2 is applied to stop the specific reel. It is the structure to make. In such a configuration, in the all-phase excitation stop control 1 and the all-phase excitation stop control 2, the drive signals of the same mode (the same mode of voltage value, current value, change speed, etc.) are used as the drive signals of the reel motors in different steps. It may be configured to output in a number (13 steps for all-phase excitation stop control 1 and 12 steps for all-phase excitation stop control 2). The number of steps in the all-phase excitation stop control 2 may be output before the step of the all-phase excitation stop control 1).

  As a configuration for outputting a drive signal of a different mode as a drive signal of a reel motor with a different number of steps (at least the number of steps in the all-phase excitation stop control 2 is before the step of the all-phase excitation stop control 1), for example, Compared with the drive signal output by the all-phase excitation stop control 2, the drive signal output by the all-phase excitation stop control 2 is a drive signal having a low voltage value or current value, and the rising change speed is By using a low drive signal, the torque when the reel motor is braked by the all-phase excitation stop control 2 becomes smaller than the torque by the all-phase excitation stop control 1, so when performing the all-phase excitation stop control 2 Even when starting all-phase excitation of a specific reel in a step prior to the step for performing all-phase excitation stop control 1, the reel is stopped at the same stop position as when performing all-phase excitation stop control 1. It is possible to allow. Further, for example, all-phase excitation is performed by the drive signal of all-phase excitation stop control 1, whereas the drive signal of all-phase excitation stop control 2 has a smaller number of excitation phases, for example, two phases, than the all-phase excitation. As a result, the torque when braking the reel motor by the all-phase excitation stop control 2 can be made smaller than the torque by the all-phase excitation stop control 1.

  The main control unit 41 according to the present embodiment performs all-phase excitation stop control 1 when the specific condition is not satisfied in the stop control of the specific reel, and stops all-phase excitation when the specific condition is satisfied. In such a configuration, the all-phase excitation stop control 2 is performed, and the all-phase excitation stop control 2 is performed so that the stop position of the symbol on the specific reel and the other There will be a slight deviation from the stop position of the symbols on the reel, but the first prize (e.g., “ "Bell-Bell-Bell" symbol combination) and a second winning combination (for example, "Cherry-any-any" symbol combination that recognizes that a winning has occurred only when a predetermined symbol stops on a specific reel) ) Including prizes In the case of a configuration that can be produced, in the reel stop control of a specific reel, when the second winning occurs and the specific condition is satisfied, the all-phase excitation stop control 2 is performed, In the case of generating a second prize that can be recognized only with the symbols stopped on the specific reel, it is difficult to recognize the deviation of the stop position between the symbols on the specific reel and the symbols on the other reels.

  The main control unit 41 according to the present embodiment performs all-phase excitation stop control 1 when the specific condition is not satisfied in the stop control of the specific reel, and stops all-phase excitation when the specific condition is satisfied. In such a configuration, the all-phase excitation stop control 2 is performed, and the all-phase excitation stop control 2 is performed so that the stop position of the symbol on the specific reel and the other There will be a slight deviation from the stop position of the symbols on the reel, but a specific symbol (for example, “7”) on a predetermined line (for example, a winning line LN, etc.) straddling the specific reel and other reels. Specific winnings (for example, a role composed of a symbol combination of “7-7-7”) that can be recognized when the symbols are aligned, and on a predetermined line straddling the specific reel and other reels. Specific symbols (for example, "7" Including a predetermined prize (for example, a role constituted by a symbol combination of “Replay-Replay-Replay”) that can be recognized when a predetermined symbol (for example, “Replay” symbol) is aligned. In a configuration in which a winning can be generated, in the reel stop control of a specific reel, when a predetermined winning is generated and a specific condition is satisfied, the all-phase excitation stop control 2 is performed. When a predetermined winning that becomes recognizable when a predetermined symbol smaller than a specific symbol is aligned on a predetermined line is generated, the deviation of the stop position between the symbol of the specific reel and the symbol of another reel is recognized. It can be difficult.

  The main control unit 41 according to the present embodiment performs all-phase excitation stop control 1 when the specific condition is not satisfied in the stop control of the specific reel, and stops all-phase excitation when the specific condition is satisfied. The control 2 can be performed, and either one of the all-phase excitation stop control 1 or the all-phase excitation stop control 2 is selected according to the symbol number of the symbol to be stopped based on the CT stop control table. In such a configuration, by performing the all-phase excitation stop control 2, the all-phase excitation stop control 2 is performed, so that the stop position of the symbol of the specific reel and the stop position of the symbols of the other reels are slightly different. However, in the stop control table for CT, when stopping a specific symbol combination on the specific reel and other reels (for example, a symbol combination constituting a winning combination), 0 If the reels are stopped with priority on sliding and the combination of specific symbols is not stopped, the number of sliding frames is set so that the reel is stopped with priority on one-frame sliding. If the specific symbol combination is not stopped on the reel, the specific condition is more easily established than when the specific symbol combination is stopped. This makes it possible to suppress the deviation of the stop position between the symbols of and the symbols of other reels.

  In this embodiment, the reel stop control is performed using a stop control table that can specify the number of sliding frames for each timing at which the stop operation is performed. When a combination of symbols (for example, a symbol combination constituting a winning combination) is to be stopped, the reel is stopped with priority to zero frame slip, and when a specific symbol combination is not to be stopped, one frame slip is performed. Set the number of sliding frames to stop the reels with priority, and search and specify the stop position that can be stopped at the timing when the stop operation is performed without using the stop control table or stop position table. Configuration to perform stop control to stop the reel at the stop position, stop control using the stop position table, search and specify stop positions that can be stopped without using the stop control table or stop position table In a configuration where stop control is performed in combination, or where stop control is performed by partially changing the stop control table or stop position table, the slip set when the stop switch is operated at a position where a specific condition can be satisfied The number of frames may be set, and even in such a configuration, when the number of sliding symbols is set for a specific reel when the gaming state is CT, a combination of specific symbols (for example, specific reels and other reels) When a combination of symbols that make up a winning combination) is stopped, the reel is stopped with priority on zero frame slip, and when a specific symbol combination is not stopped, priority is given to one frame slip. If you set the number of sliding frames to stop the reels and do not stop the specific symbol combination on the specific reel and other reels, the specific symbol combination The than stopping, when a particular condition is easily obtained, when a combination of specific symbols are stopped, it is possible to suppress the deviation of the stop position for the symbol of the symbol and the other reel particular reel.
