Description

  The present invention relates to a gaming machine such as a slot machine including a rotating drum and a stepping motor that rotationally drives the rotating drum.

  2. Description of the Related Art Conventionally, a gaming machine (a spinning machine, slot machine) having a plurality of spinning cylinders having symbols arranged on an outer peripheral surface is known. This type of gaming machine gives a certain game value to a game medium (medal) and performs a game for acquiring such a game medium. In addition, this type of gaming machine has an internal lottery triggered by the player's rotation start operation and starts rotation of a plurality of spinning cylinders, and a mode according to the result of the internal lottery as a player's stop operation trigger. In order to stop multiple cylinders. The game result is determined by a combination of symbols displayed on the winning determination line in a state where a plurality of spinning cylinders are stopped, and medals are paid out according to the game result.

  Also, some slot machines move the spinning cylinder when notifying internal winnings. Normally, the spinning cylinder rotates at the start of the game by pressing the start switch, and stops when the stop button is pressed, but in a slot machine with a rendering function by the spinning cylinder, the period from the start switch pressing to the stop button pressing More precisely, during a period from when the start switch is pressed to when the rotating cylinder becomes a steady rotation, an internal winning may be notified by performing a special operation such as irregularly moving each rotating cylinder up and down. Since the movement of the spinning cylinder in a normal game is regular in one direction and at a constant speed, it can be easily distinguished from the movement of the spinning cylinder due to performance. Such an operation of the rotating cylinder is called a rotating effect.

  As a motor for rotating a spinning cylinder of a gaming machine, a stepping motor having a four-phase winding (coil) as a stator is used. A stepping motor includes a gear-shaped iron core or permanent magnet as a rotor (rotor), a plurality of windings (coils) as a stator (stator), and is rotated by switching windings through which current flows. is there. When a current is passed through each winding in turn, the motor rotates according to the winding through which the current is passed, and when a current is passed in the reverse order, the motor rotates in the reverse direction. In the following description, flowing current through the winding is referred to as “excitation”.

  The excitation procedure for rotating the motor will be described with reference to FIGS. For the way of viewing FIGS. 11 and 14, refer to the description of FIG. 5 described later.

  FIG. 14 shows an excitation procedure when starting a game by pressing a start switch, that is, an excitation procedure for rotating the spinning cylinder in a normal game. As indicated by the circles in FIG. 14, one or two of the four windings are excited in units of a predetermined time in the order from the fourth winding to the first winding. Next to the excitation of the first winding, the excitation returns to the excitation of the fourth winding. In FIG. 14, time = 1 unit time, but for example, 1 unit time = 1.5 ms. Since the rotation of the spinning cylinder in the normal game is unidirectional and at a constant speed, the excitation shown in FIG. 14 is repeated until the spinning cylinder is stopped by pressing the stop button (or when a predetermined time has elapsed).

  FIGS. 11A and 11B show an excitation procedure in the spinning effect. FIG. 11 (a) shows an excitation procedure for rotating in the opposite direction to the rotation of the spinning cylinder in the normal game, and FIG. 11 (b) is for rotation in the same direction as the rotation of the spinning cylinder in the normal game. This is the excitation procedure. 11 (a) and 11 (b), one or two of the four windings are arranged in the order from the first winding to the fourth winding, or from the fourth winding to Excitation is performed in units of a predetermined time in the order of one winding. When the excitation shown in FIG. 11A is repeated for a predetermined time, the excitation shown in FIG. 11B is repeated for a predetermined time. In the spinning effect, these excitations are repeated a predetermined number of times. In FIGS. 11A and 11B, time = 2 unit time, but for example, 2 unit time = 3 ms. If the excitation time is long, the rotation speed becomes low. In the above example, the rotation speed during the spinning effect is half of the rotation speed in the normal game.

  The movement of the rotating cylinder in the rotating effect will be described with reference to FIG. This figure is a graph measuring the speed change of one cylinder.

  The horizontal axis is time, and the width of one of the lattices is 200 ms. In FIG. 15A, t2 'is the time when 200 ms has elapsed from t1'. The same applies to t3 'and t4'. t0 'is the start timing of the spinning effect (the timing at which a current is passed through the winding to perform the spinning effect and the excitation is started). Before starting the measurement (before t0 '), a process for returning the rotating drum to the measurement position, that is, a preparation process for measurement, is performed. The movement starting from tx corresponds to the process, which is independent of the spinning effect. Hereinafter, only the operation after t0 'will be described.

  The vertical axis represents the speed of the rotating drum. The + direction (upward on the graph) corresponds to the movement in the rotating direction of the spinning cylinder in normal games, and the-direction (downward on the graph) corresponds to the movement in the opposite direction (upward as viewed from the player). .

  As can be seen from FIG. 15A, first, the excitation of FIG. 11A is performed and the rotating cylinder moves in the − direction, and then the excitation of FIG. 11B is performed and moves in the + direction. Such a rotation direction is frequently switched, that is, a movement that vibrates the rotating cylinder is one of the rotating effects. In the illustrated example, the period is about 60 ms. In addition, since the top and bottom are almost symmetrical (the + area and the − area of the graph are almost equal), the rotator vibrates around the same symbol. Since the movement of the spinning cylinder in the normal game is regular in one direction and at a constant speed, the movement of the spinning cylinder shown in FIG. 15A can be easily distinguished from the movement of the normal game.

  In order to perform the movement shown in FIG. 15A, a current is passed through each winding in an order opposite to that of the normal game for a certain period of time (for example, about 30 ms), and thereafter Current is passed through and is repeated. The rotation speed can be adjusted by changing the winding time (in other words, the time for passing a current through one winding). As described above, when the rotation speed in the spinning effect is halved in the normal game, the winding switching time in the spinning effect may be twice as long as the winding switching time in the normal game. .

JP, 2011-204, A In order to prevent a failure or malfunction associated with heat generation, when a predetermined condition that causes a rise in temperature of the driving means of the game machine is satisfied, it is more than before the predetermined condition is satisfied. An effect in which the number of operations per unit time of the movable member is reduced is executed. Various controls for reducing the temperature of the motor that drives the rotating drum may be performed based on the temperature and excitation state of the motor (paragraph 0179). JP, 2005-137475, A In order to suppress heat generation at the time of driving, the slot machine is provided with temperature detecting means for detecting the temperature of the motor that moves the rotating drum, and whether or not the temperature detected by the temperature detecting means has reached a specified value. When the specified value is reached, the drive current supplied to the motor is reduced. JP, 2003-305217, A In a game machine, such as a pachinko machine and an arrangement ball machine, in order to suppress driving of a driving body (motor) and prevent overheating of the driving body, driving of the driving body is suppressed based on temperature. Temperature management means 5 for performing Since the temperature management means suppresses or stops the driving of the driving body 2 based on the temperature before the driving body overheats, the overheating of the driving body can be prevented.

  By performing the control as described above, it is possible to perform a spinning effect as shown in FIG. 15A, but it has been found that a problem arises in a specific situation. For example, if a game is played for a long time at a relatively high ambient temperature (air temperature) and the temperature rises due to the heat generated by the motor, the motor torque will drop, causing problems such as step-out. End up.

  FIG. 15B shows a graph when the above-mentioned trouble occurs. The graphs and symbols in FIG. 15B are the same as those in FIG.

  In FIG. 15A, the upper and lower sides of the graph are almost symmetrical, and the rotating cylinder vibrates so as to draw a clean sine wave around the same pattern, but in the graph of FIG. It is irregular. Step-out occurs at a time point before t2 'in FIG. In the case of FIG. 15 (a), the player seems to vibrate in the case of FIG. 15 (a), but in the case of FIG. 15 (b), it seems that the case is slippery and slips far from the vibration operation. It has become an operation.

  As a prior art disclosing countermeasures when the motor is overheated, there are Patent Documents 1 to 3 described above.

  Patent Document 1 attempts to lower the temperature by stopping some operations when the temperature rises, and does not allow normal operation to be performed even when the temperature rises.

  Patent Documents 2 and 3 attempt to lower the temperature by lowering the drive current of the motor when the temperature rises, and do not cause normal operation even when the temperature rises.

  Moreover, although patent documents 1-3 are all disclosing the control of the rotation of a normal game, there is no description about the control of the rotation in a rotation effect.

  If the cause is heat generation of the motor, the problem is solved by natural cooling if the operation is stopped for a certain period of time. However, during that time, not only the spinning performance but also normal games can no longer be performed. Alternatively, a cooling means may be provided in the motor, but this causes an increase in cost.

  An object of the present invention is to provide a gaming machine that can solve the problem of the spinning effect caused by the heat generated by the motor without affecting the execution of the spinning effect and increasing the cost.

The present invention provides a reel unit including a plurality of spinning cylinders, a plurality of motors for rotating the plurality of spinning cylinders, a start switch for starting rotation of the plurality of spinning cylinders, and the plurality of motors, respectively.

  1 and 2, reference numeral 100 denotes a slot machine. As shown in FIG. 1, the slot machine 100 can be opened and closed by a hinge or the like on the slot machine main body 120 and one side of the front surface of the slot machine main body 120. And a front door 130 attached thereto. As shown in FIG. 1, a game display unit 131 is provided substantially in the center of the front door 130, and a medal insertion slot 132 for a player to insert medals is provided at the lower right corner of the game display unit 131. Provided below the medal insertion slot 132 is a reject button 133 for forcibly discharging a clogged medal inserted from the medal insertion slot 132 to the outside of the slot machine 100.

  Further, a start switch 134 for starting a game is provided on the lower left side of the game display unit 131, corresponding to each of the three spinning cylinders (first to third cylinders 40a to 40c). Three stop buttons 140 are provided. A medal payout port 135 is provided at the center of the lower end of the front door. A liquid crystal display device LCD is provided on the right side of the game display unit 131.

  As shown in FIG. 2, the slot machine main body 120 is fixed to the inner bottom surface, stores a plurality of medals therein, and stores the stored medals at a payout port 135 provided on the front surface of the front door 130. A hopper device 121 for paying out the sheets one by one is installed. An upper portion of the hopper device 121 is provided with a hopper tank 122 that opens upward and stores a plurality of medals therein. Inside the slot machine main body 120, a reel unit 203 including three spinning cylinders 40a, 40b, and 40c is installed at a position where the game display unit 131 comes when the front door 130 is closed. The reel unit 203 includes three spinning cylinders 40a, 40b, and 40c in which a plurality of types of symbols are arranged on the outer peripheral surface. The game display unit 131 is provided with an opening, through which a player can see the symbols of the reels 40a, 40b, and 40c of the reel unit 203. A power supply unit 205 is provided between the upper hopper unit 121 and the reel unit 203.

  As shown in FIG. 2, the medal (coin) selector 1 is attached to the back side of the front door 130 on the back side of the medal slot 132 provided on the front surface of the front door 130. This medal selector 1 rolls the medal toward the hopper device 121 while detecting the passage of the medal inserted from the medal insertion slot 132, and has a different diameter medal or iron or iron whose outer diameter is different from the predetermined dimension. This is an apparatus for selecting and removing illegal medals made of an alloy and selecting and eliminating a predetermined number or more of medals that can be inserted per game.

  Further, as shown in FIG. 2, a lead-out path 136 that covers the lower side and communicates with the payout port 135 of the front door 130 is provided below the medal selector 1. The medals distributed by the medal selector 1 are returned to the player from the payout port 135 via the derivation path 136.

FIG. 3 shows a functional block diagram of the slot machine 100 according to the embodiment of the invention.
In this figure, the display about the power supply system is omitted. Although not shown, the slot machine includes a power supply unit for generating a DC power supply (+5 V or the like) from a commercial power supply (AC 100 V).

  The slot machine 100 includes a main substrate (processing unit) 10 and a sub substrate 20 that operates in response to a command from the main substrate (processing unit) 10 as main processing devices. At least the main substrate 10 is accommodated inside the case so that it cannot be contacted from the outside, and is sealed so that traces remain when these substrates are removed.

  The main board 10 is used for performing an internal lottery in response to the player's operation, and for performing processing such as rotation / stop of the spinning cylinders 40a, 40b, and 40c and payout of medals. The main board 10 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub board 20 is for receiving a command signal from the main board 10 and notifying the result of the internal lottery and performing various effects. The sub-board 20 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  The main board 10 has a bet switch BET, a start switch 134, a stop button 140, a rotation position detector 159 of the reel unit 203, a stepping motor 155, a hopper driving unit 80, a hopper 81, and medals paid out from the hopper 81. A medal detection unit 82 for counting the number of sheets (these constitute the hopper device 121 described above) is connected. A peripheral substrate (local substrate) such as a liquid crystal control substrate 200 for controlling the liquid crystal display device, a speaker substrate 201, and an LED substrate 202 is connected to the sub substrate 20.

  Further, medal sensors S1 and S2 of the medal selector 1 are connected to the main board 10.

  The medal selector 1 is provided with medal sensors S1 and S2 for counting medals. The medal sensors S1 and S2 are provided on the downstream side (near the exit) of a medal passage (not shown) provided in the medal selector 1 (the upstream side of the medal passage communicates with the medal slot 132). The two medal sensors S1 and S2 are arranged side by side at a predetermined interval along the medal traveling direction. The medal sensors S1 and S2 are, for example, photointerrupters that have a light emitting portion and a light receiving portion that face each other, are formed in a U-shaped cross section, and are positioned so that the detection optical axis faces the medal passage from above. . Each photo interrupter detects the passage of a medal sent without being blocked on the way. The reason why two photo interrupters are adjacent is not only to detect the number of medals but also to monitor whether or not the passage of medals is normal. That is, by providing two photo interrupters adjacent to each other, it is possible to detect the passing speed and passing direction of medals, thereby detecting not only the number of medals but also an illegal act moving in the reverse direction.

  The hopper driving unit 80 rotates the hopper 81 and performs an operation of paying out medals of the payout number instructed by the main board 10. The gaming machine includes a medal detection unit 82 that operates every time a medal is paid out, and the main board 10 receives a medal actually paid out from the hopper 81 based on an input signal from the medal detection unit 82. You can manage the number.

  The insertion accepting unit 1050 receives the outputs of the medal sensors S1 and S2 of the medal selector 1, accepts the insertion of medals for each game, and determines that the medal corresponding to the specified number of insertions has been inserted. A process of permitting the rotation start operation of the first cylinder 40a to the third cylinder 40c is performed. Note that the pressing operation of the start switch 134 is an opportunity to start the rotation of the first cylinder 40a to the third cylinder 40c, and is an opportunity to execute the internal lottery. Also, a prescribed number of insertions is set according to the gaming state, the prescribed number of insertions is set to 3 in the normal state and the bonus establishment state, and the prescribed number of insertions is set to 1 in the bonus state.

  When medals are inserted, the inserted medals are set to the inserted state up to a specified number of insertions according to the gaming state. Alternatively, when the bet switch BET is pressed in a state where medals have been credited to the gaming machine, the credited medals are set to the inserted state by limiting the prescribed number of insertions according to the gaming state. The main board 10 controls whether or not to accept a medal. When it is not in a state of accepting insertion of medals (when not permitted), even if medals are inserted, they are not counted by the medal sensors S1 and S2 and are returned as they are. Similarly, the main board 10 controls the validity / invalidity of the bet switch BET. When the bet switch BET is not valid (when not permitted), even if the bet switch BET is pressed, it is ignored.

  The main board 10 incorporates random number generating means 1100. The random number generation means 1100 is a means for generating a random number for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts numerical values so as to circulate a predetermined count range). In the embodiment of the present invention, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, its acquisition timing is irregular. Includes a value that can substantially function as a random number.

  The internal lottery means 1200 performs an internal lottery in which the player determines whether or not the winning combination is based on a start signal from the start switch 134. That is, a lottery table selection process for selecting a lottery table (not shown) stored in a memory (not shown) of the main board 10, a random number determination process for determining the winning of a random number obtained from the random number generating means 1100, The lottery flag setting process for setting a flag to that effect when a big win or the like is won by the determination result is performed.

  In the lottery table selection process, a lottery table (not shown) stored in a storage unit (ROM) (not shown) is used to determine which lottery table is used for internal lottery. In the lottery table, for each of a plurality of random values (for example, 65536 random values from 0 to 65535), replay, small role (bell, cherry), regular bonus (RB: bonus), and big bonus (BB :), etc., are associated with each other. In addition, a normal state, a bonus establishment state, and a bonus state can be set as the gaming state, and a replay lottery state, a replay low probability state, and a replay high probability state can be set as the replay lottery state.

  In the random number determination process, a random value (lottery random number) is acquired from the random number generation means (not shown) for each game based on a start signal from the start switch 134, and the lottery table is referred to for the acquired random value. Then, it is determined whether or not the winning combination is won.

  In the lottery flag setting process, the lottery flag of the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state, on Status). When two or more types of winning combinations are won, a lottery flag corresponding to each of the two or more types of winning winning combinations is set to the winning state. The lottery flag setting information is stored in storage means (RAM).

  A lottery flag (possible carryover flag) that can carry over the winning state for the next game until winning, and a lottery flag that is reset to the non-winning state without bringing the winning state to the next game regardless of winning Carry-over impossible flag) may be provided. In this case, there are a regular bonus (RB) and a big bonus (BB) as a combination to which the former carry-over possible flag is associated, and other combinations (for example, small role, replay) correspond to the latter carry-over impossible flag. It is attached. In other words, in the lottery flag setting process, when a regular bonus is won by internal lottery, the winning state of the regular bonus lottery flag is carried over until the regular bonus is won, and when a big bonus is won by internal lottery, A process of carrying over the winning state of the flag until the big bonus is won is performed. At this time, the main board 10 determines whether or not the bonuses (small role and replay) other than the regular bonus and the big bonus are played even if the winning state of the regular bonus or big bonus lottery flag is carried over by the internal lottery function. An internal lottery is performed. In other words, in the lottery flag setting process, in a game in which the winning state of the regular bonus lottery flag is carried over, if a small role or replay is won in the internal lottery, the regular bonus lottery flag and the internal lottery already won In a game in which the lottery flags corresponding to two or more types of winning combinations or replay lottery flags won in the win state are set to the winning state and the winning state of the big bonus lottery flag is carried over, it is small in the internal lottery When a winning combination or replay is won, a lottery flag corresponding to two or more kinds of winning combinations including a big bonus lottery flag that has already been won and a small bonus or replay lottery flag that has been won in an internal lottery is set to a winning state. Set.

  The replay processing unit 1600 may perform control to change the winning probability of replay in the internal lottery under a predetermined condition. The replay processing unit 1600 will be described later again. The replay lottery states include a replay no lottery state in which replay is excluded from the internal lottery, a replay low probability state in which the replay winning probability is set to approximately 1 / 7.3, and a replay winning probability of approximately 1 / A plurality of lottery states such as a high replay probability state set to 6 can be set. By changing the replay lottery state, the winning probability of the replay in the internal lottery is changed.

  The spinning cylinder control means 1300 drives the first spinning cylinder 40a to the third spinning cylinder 40c by a stepping motor based on a start signal generated by the player pressing the start switch 134 (rotation start operation), and performs first driving. The three stop buttons 140 respectively corresponding to the rotating cylinder in a state where the rotation speed of the rotation cylinder 40a to the third rotation cylinder 40c has reached a predetermined speed (about 80 rpm: a rotation speed of about 80 rotations per minute). In addition to performing control to permit the pressing operation (stop operation), the first cylinder 40a to the third cylinder 40c that are rotationally driven by the stepping motor are stopped according to the setting state of the lottery flag (internal lottery result). Take control.

  In addition, when the player presses the three stop buttons 140 in a state where the pressing operation (stop operation) with respect to the three stop buttons 140 is permitted (validated), Based on the signal, the supply of the drive pulse (motor drive signal) to the stepping motor of the reel unit 203 is stopped, thereby performing control to stop each of the first cylinder 40a to the third cylinder 40c.

  That is, each time the three stop buttons 140 are pressed, the spinning cylinder control means 1300 sets the stop position of the spinning cylinder corresponding to the pressed button among the first spinning cylinder 40a to the third spinning cylinder 40c. Control is performed to stop the spinning cylinder at the determined stop position. Specifically, referring to a stop control table (not shown) stored in the storage means (ROM), the first time corresponding to the pressing timing, pressing order, etc. of the three stop buttons (mode of stop operation) The stop position of the cylinder 40a to the third cylinder 40c is determined, and control is performed to stop the first cylinder 40a to the third cylinder 40c at the determined stop position.

  Here, in the stop control table, the positions of the first cylinder 40a to the third cylinder 40c (pressing detection position) at the time when the stop button 140 is operated, and the actual stop positions of the first cylinder 40a to the third cylinder 40c. (Or the number of sliding frames from the pressed detection position) is set. Depending on the setting state of the lottery flag, a stop control table for determining the stop positions of the first cylinder 40a to the third cylinder 40c may be prepared.

  In the gaming machine, the reel unit 203 is provided with a reel index (shielding plate 160 in FIG. 7) made of a photosensor, and the spinning cylinder control means 1300 is a reference position detected by the reel index every time the spinning cylinder makes one rotation. Based on the signal, monitoring the current rotation state of the rotating cylinder by obtaining the rotation angle (number of rotation steps of the rotating shaft of the stepping motor) from the reference position of the rotating cylinder (the frame detected by the reel index) Can be done. That is, the main board 10 can obtain the position of the rotating cylinder when the stop button 140 is operated by obtaining the rotation angle from the reference position of the rotating cylinder.

  The spinning cylinder control unit 1300 performs so-called pull-in processing and kicking processing as control for stopping the spinning cylinder. The pull-in process is a control for stopping the spinning cylinder so that the symbol corresponding to the combination whose lottery flag is set to the winning state is stopped on a valid winning determination line (so that the winning combination can be won). It is processing. On the other hand, the kicking process means that the symbol corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on a valid winning determination line (so that a non-winning combination cannot be won) Is a control process for stopping the process. In other words, in the gaming machine according to the embodiment of the present invention, the lottery flag setting state, the stop button 140 pressing timing, the pressing order, and the stopping position of the already-rotated cylinder ( The stop control table is set so that the stop position of each cylinder changes according to the type of display symbol). In this way, the main board 10 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state is in the winning form. Control is performed to stop the first cylinder 40a to the third cylinder 40c so as not to stop.

  In the gaming machine according to the embodiment of the present invention, the first to the third torso 40a to the third torso 40c are rotated in response to the pressed stop button within 190 ms from the time when the stop button 140 is pressed. The control state is set to stop That is, in the stop control table for determining the stop position of each rotating cylinder, the number of frames required from when the stop button 140 is pressed until each cylinder stops is in the range of 0 to 4 frames (predetermined pull-in range).

  The rotation control means 1300 also performs control related to the rotation effect. Some slot machines move the spinning cylinder when notifying internal winnings. Normally, the spinning cylinder rotates at the start of the game by pressing the start switch, and stops when the stop button is pressed, but in a slot machine with a rendering function by the spinning cylinder, the period from the start switch pressing to the stop button pressing More precisely, during the period from when the start switch is pressed to when the spinning cylinder can be stopped by the player, the internal winnings are notified by performing special actions such as irregularly moving the spinning cylinder up and down. (Since the movement of the spinning cylinder in a normal game is regular in one direction and at a constant speed, it can be easily distinguished from the movement of the spinning cylinder due to performance). Such an operation of the rotating cylinder is called a rotating effect. It should be noted that, even in the spinning effect, the player can perform an operation of making the push operation of the stop button effective and temporarily stopping (pseudo-stopping) the spinning cylinder being produced, which is also included in the spinning effect.

  It should be noted that the above-mentioned spinning effect may be performed after all the spinning cylinders have been stopped and before the medal insertion acceptance start relating to the next game.

  Although it has been described above that the winning determination is not performed in the pseudo stop operation, the present invention is not limited to this, and the winning determination may be performed also in the spinning effect. For example, when a predetermined symbol combination (for example, “7, 7, 7”) can be aligned by pressing at the time of a pseudo stop, so-called AT (navigation of symbol combination corresponding to winning combination or navigation in pushing order), etc. May be given to the player. By doing so, it is possible to give the player motivation to perform a pseudo stop during the spinning effect, and to cause the player to smoothly perform the pseudo game (pseudo stop operation). This is particularly suitable when a time limit is set for the revolving effect (a time limit that is set when the revolving effect is started, and when the time is up, the revolving effect ends and the sequence toward steady rotation starts). It is.

  When the above-mentioned spinning effect is completed, a process (sequence) for performing steady rotation in the normal direction is started immediately after that.

  The winning determination means 1400 performs a process of determining whether or not a winning combination has been won based on the stopping modes of the first to fourth cylinders 40a to 40c. Specifically, the winning determination line is displayed on the winning determination line when all of the first cylinder 40a to the third cylinder 40c are stopped while referring to the winning determination table stored in the storage means (ROM). It is determined whether or not the symbol combination is a predetermined winning combination.

  The winning determination means 1400 executes a winning process based on the determination result. As a process at the time of winning a prize, for example, when a small role wins, the hopper 81 is driven to perform a medal payout control process, or a credit is increased (a predetermined maximum number is increased to 50, for example, When the replay is won, a replay process is performed. When a big bonus or a regular bonus is won, a game state transition control process for shifting the game state is performed.

  The payout control means 1500 performs payout control processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is determined based on a payout predetermined for each combination, and the medals corresponding to the determined number of payouts are determined by the hopper driving unit 80. Then, the hopper 81 is driven to pay out. At this time, a current flows through a motor (not shown) built in the hopper 81.

  When medal credits (internal storage) are permitted, instead of actually paying out medals by the hopper 81, the number of credits stored in a credit storage area (not shown) of the storage means (RAM) (not shown) A credit addition process for adding the number of payouts to the number of credited medals is performed to virtually pay out medals.

  When the replay is won, the replay processing means 1600 performs a replay process (regame process) for setting the same preparatory state as the previous game without requiring insertion of medals owned by the player for the next game. When a replay wins, an automatic insertion process is performed in which the same number of medals as the previous game is automatically set to the insertion state without using the player's own medals (including credit medals). The game machine is set in a state of waiting for a rotation start operation (pressing operation of the start switch 134 by the player) in the next game in a state where the same winning determination line as the previous game is validated.

  Further, the main board 10 may perform control to shift the gaming state between the normal state, the bonus establishment state, and the bonus state (gaming state transition control function). As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. When a plurality of conditions are established, transitioning the gaming state to another gaming state based on the fact that one of the plurality of conditions is satisfied or all of the plurality of conditions are satisfied Can do.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the bonus establishment state is possible. The bonus establishment state is a gaming state that shifts when a big bonus or a regular bonus is won in the internal lottery. In the bonus establishment state, when the big bonus is won in the internal lottery in the normal state, the lottery flag corresponding to the big bonus is maintained in the winning state until the big bonus is won, and the regular bonus is won in the internal lottery in the normal state Until the regular bonus is won, the lottery flag corresponding to the regular bonus is maintained in the winning state. In the bonus state, it is determined whether or not the end condition is satisfied based on the total number of medals paid out by the bonus game, and medals exceeding a predetermined payout limit number are paid out according to the type of bonus won. The bonus state is terminated and the gaming state is returned to the normal state.

  The reel unit 203 includes three spinning cylinders 40a to 40c, and one stepping motor 155a to 155c is attached to each of the three spinning cylinders 40a to 40c. The stepping motors 155a to 155c include a gear-shaped iron core or permanent magnet as a rotor (rotor), a plurality of windings (coils) as a stator (stator), and rotate by switching windings through which current flows. It is what That is, a current is passed through the windings of the stator to generate a magnetic force, and the rotor is rotated by attracting the rotor. Since the rotation axis can be stopped at a specified angle, it is used to drive the rotation of the slot machine. As the number of phases (windings), for example, there are two (two phases), four (four phases), and five (five phases).

  Stepping motors include unipolar and bipolar types.

  The unipolar type is provided with a winding provided with a center tap, and is suitable for a method in which a current is always supplied to one winding in a fixed direction (unipolar driving). This drive system has the advantage that the drive circuit is simple, but on the other hand, the use efficiency of the winding is bad (1/2 compared to the bipolar drive below) and the output torque at low speed is low. There is.

  The bipolar type is suitable for a system (bipolar drive) in which a normal winding without a center tap is provided and current is bidirectionally supplied to one winding. This driving method has a demerit that the driving circuit becomes complicated, but has an advantage that the use efficiency of the winding is good and the output torque at the time of low-speed rotation becomes high.

  The embodiment of the present invention can be applied to both unipolar and bipolar stepping motors.

  The stepping motor can change its characteristics (excitation mode changes) by changing the way of applying current to the windings of each phase. The two-phase type is as follows.

• Single-phase excitation Always allow current to flow through only one phase of the winding. Positioning accuracy is good.

・ Two-phase excitation
Current flows in two phases. An output torque approximately twice that of single-phase excitation can be obtained. The positioning accuracy is good and the stationary torque is large when stopped, so that the stop position can be held reliably.

・ One-two-phase excitation
A current is passed by alternately switching between one phase and two phases. Since the step angle can be halved in the case of one-phase excitation and two-phase excitation, smooth rotation can be obtained.

  In the slot machine, for example, a four-phase (winding) stepping motor having a basic step angle of 1.43 degrees is used, and one-two-phase excitation is adopted as a pulse output method.

  FIG. 4 is a block diagram of a drive circuit of the stepping motor 155 of the slot machine. In FIG. 4, elements such as an index for detecting the position of each cylinder are omitted.

  In the figure, reference numerals 1310-1 to 1310-3 denote drive circuits for switching on and off (whether or not current flows) of the A-phase winding and the B-phase winding of the stepping motors 155 a to 155 c. Reference numerals 1320-1 to 1320 are excitation circuits for supplying current to the A-phase winding and the B-phase winding of the stepping motors 155 a to 155 c in accordance with the outputs of the drive circuits 1310-1 to 1310-1. The A-phase winding of the stepping motor 155a is indicated by reference numeral 155a-A, and the B-phase winding is indicated by reference numeral 155a-B. The A phase winding and B phase winding of the stepping motors 155b and 155c are not shown.

  The A-phase winding includes two windings, A and / A. The B-phase winding includes two types of windings B and / B. The A-phase winding and the B-phase winding are alternately arranged, for example, A, B, / A, / B,. When excited in the order of A → B → / A → / B →..., The motor rotates in one direction, and when excited in the order of / B → / A → B → A →. If the interval for switching the excitation of each phase is shortened, the motor rotates faster, and if the interval is increased, the motor rotates slower. If the current continues to flow through the same stator without switching the exciting winding here, the rotor is fixed at the same stator position, and the motor keeps the current position.

  FIG. 5 is an explanatory diagram of a driving method of the stepping motor of the slot machine. The figure shows an example of one-two-phase excitation. A circle in the table indicates that a current is flowing through the winding. When the current is passed through the windings in the order of steps 1, 2,..., 8 in the table of the figure, the motor rotates, and in the reverse order, the motor rotates in the reverse direction.

  Next, a specific configuration of the rotating drum (reel) will be described.

  6A is a front view of the reel unit 203, and FIG. 6B is a left side view thereof.

  As shown in FIG. 6A, each of the drums 40a to 40c is configured as a reel unit 203, and is attached to the frame 151 via a bracket or the like (not shown). Further, stepping motors 155a to 155c are provided in each of the spinning cylinders 40a to 40c, and each of the spinning cylinders 40a to 40c is driven by these motors 155a to 155c to rotate.

  The frame 151 that is the main body of the reel unit 203 is a substantially U-shaped metal member (aluminum plate) whose sides are slightly larger than the diameter of the rotating drum (the rear side, that is, the back side of the gaming machine is open). The width is larger than the sum of the widths of the three cylinders 40a to 40c. The substantially U-shaped open side may be the front side.

  The front-side end of the lower surface of the frame 151 as viewed from the front of the gaming machine is bent in a small L shape downward in FIG. 7, and fixing holes for the reel unit 203 are provided at both ends of the portion. Yes. The reel unit 203 is fixed to the inside of the gaming machine by inserting the screw 161b into the screw hole of the substantially horizontal lower bar 161 connected to the frame of the gaming machine. In FIG. 6, the connection state of the lower bar 161 and the frame (not shown) of the gaming machine is not shown, but the end portions 161a of the lower bar 161 are each firmly connected to the frame of the gaming machine housing. .

  Further, in FIG. 6, the upper bar 162 is similarly provided at the upper end of the front side of the reel unit 203, and screws 162 b are respectively inserted into fixing holes provided at both ends of the upper back of the frame 151. The reel unit 203 is fixed inside the gaming machine by firmly tightening the screw hole of the upper bar 162. In FIG. 6, the connection state of the upper bar 162 and the frame (not shown) of the gaming machine is not shown, but the end portions 162a of the upper bar 162 are each firmly connected to the frame of the gaming machine.

  That is, according to FIG. 6, the reel unit 203 is fixed at both the upper end and the lower end of the front surface thereof.

  The structure of each of the spinning cylinders 40a to 40c is shown in FIG.

  Each of the spinning cylinders 40 a to 40 c is configured such that a band 154 is attached to the outer periphery of the drum 153. A pattern is drawn on the outer peripheral surface of the belt 154.

  A lamp case 156 is provided inside the drum 153 behind the belt 154, and back lamps 157a, 157b, and 157c are attached to the three rooms of the lamp case 156, respectively. These back lamps 157 a to 157 c are mounted on a substrate 158 as shown in FIG. 7B, and the substrate 158 is attached to the back of the lamp case 156. Further, a rotating drum position detector 159 is attached to the bracket 152. The rotating cylinder position detector 159 is a photo interrupter. In this case, a light emitting element (such as a light emitting diode) and a light receiving element (such as a phototransistor and a photodiode) are arranged to face each other in one case, and a detection groove is provided therebetween. It is provided to detect that an object has passed between the detection grooves in a non-contact manner. The rotation position detector 159 detects that the shielding plate 160 provided on the drum 153 passes through the rotation position detector 159 as the drum 153 rotates. The detection signal of the shielding plate 160 output from the rotation position detector 159 is also called an index detection signal and is sent to the main board 10.

  The back lamps 157a to 157c are individually controlled to be turned on by a lamp driving circuit (not shown). By turning on each of the back lamps 157a to 157c, among the symbols drawn on the belt 154, the three symbols located at the front of each back lamp 157 are individually illuminated from behind, and 3 symbols are respectively displayed on the symbol display window 13. Individual designs are projected.

  FIG. 8 shows a process flowchart of the spinning effect in the gaming machine according to the embodiment of the invention. First, with reference to the timing charts of FIG. 8 and FIG. The details of the spinning effect (especially preliminary operation) will be described later.

  The flowchart of FIG. 8 eliminates the problem of the rotating effect due to the heat generated by the motor by performing a preliminary operation before performing the rotation processing related to the conventional rotating effect.

ST10: Preliminary operation (1)
By exciting the two windings of the stepping motor 155 for a long time, the rotor is securely held. The excitation time here is the first time T1. The windings to be excited are the same, and the windings are not switched.

ST11: Preliminary operation (2)
The rotor is rotated while switching the winding to be excited. At that time, the excitation time is gradually shortened. “Slowly shortening” does not mean only a monotonous decrease, but instead of or together with this, the last excitation time is shorter than the first excitation time, and the latter half is more average than the first half. The meaning of the degree of shortening is included. The time for energizing one winding is the second time. There are a plurality of second times.

ST12: Rotation processing related to the spinning drum effect Perform operations such as moving each spinning drum up and down irregularly. Since this process is publicly known, detailed description is omitted. The time for exciting one winding is the third time.

  For the first time, the second time, and the third time, for example, a relationship of first time> second time ≧ third time is established. In addition, about the 2nd time, those average values may be calculated | required and the said relationship may be materialized.

  8 is moved as shown in FIG. FIG. 9A is a graph in which the speed change is measured for one rotating cylinder, and FIG. 9B is a diagram in which the horizontal axis is doubled.

  In FIG. 9A, the horizontal axis is time, and one of the lattices is 200 ms. In FIG. 9A, t2 is the time when 200 ms elapses from t1. The same applies to t3 and t4. t0 is the start timing of the process S10 in FIG. ta is the timing at which the processing S11 in FIG. 8 is terminated and S12 is started. That is, the period from t0 to ta is a period during which the preliminary operation consisting of S10 and S11 in FIG. 8 is executed.

  In addition, before starting the measurement (before t0), a process for returning the rotating drum to the measurement position, that is, a preparation process for measurement is performed. The movement starting from tx corresponds to the process, which is a process unrelated to the spinning effect, and the description thereof is omitted.

  The vertical axis represents the speed of the rotating drum. The + direction corresponds to the movement of the rotating cylinder in the normal game, and the − direction corresponds to the movement in the opposite direction (upward as viewed from the player).

  As can be seen from FIG. 9A, the preliminary operation is first performed, and then the spinning effect is performed. In the spinning effect, the spinning cylinder moves in the-direction and then moves in the + direction. Such a rotation direction is frequently switched, that is, a movement that vibrates the rotating cylinder is one of the rotating effects. In the illustrated example, the period is about 60 ms. Further, after time ta, the upper and lower sides are almost symmetrical (the area of + in the graph and the area of − are almost equal), so that the rotating cylinder vibrates around the same symbol. Since the movement of the spinning cylinder in the normal game is regular in one direction and at a constant speed, the movement of the spinning cylinder after the time ta shown in FIG. 9A can be easily distinguished from the movement of the normal game. it can.

  On the other hand, the period from t0 to ta during the preliminary operation is not vertically symmetrical and is not a regular movement, but its duration is relatively short (57 unit hours, about 85.5 ms), and This is a movement that is difficult for the player to notice because it is only the first action. Therefore, for the player, the spinning effect of the gaming machine according to the embodiment of the invention looks the same as the conventional spinning effect.

  In FIG. 9B, the horizontal axis is time, and one of the lattices is 100 ms. The vertical axis is the same as in FIG.

  Reference numerals t0 to t4 and ta in FIG. 9B correspond to those in FIG. 9A.

  tb is the first rotation direction switching timing of the rotation process related to the spinning effect after the preliminary operations ST10 and ST11 are completed. Similarly, tc, td, and te are timings for switching the rotation direction.

  Regardless of the influence of the heat generated by the motor, the movement is as shown in FIGS. The waveform does not become as shown in FIG. By adding the preliminary operation as in the process of FIG. 8, even if the motor generates heat and the torque decreases, the waveform and operation are almost the same as in the state where no heat is generated.

  According to the embodiment of the present invention, by performing a preliminary operation before the turning effect, even if the torque is reduced during the heat generation of the motor, a malfunction such as a step-out does not occur, and the intended turning effect is always performed. Is possible.

  Next, a specific excitation procedure according to the embodiment of the invention will be described with reference to FIGS. The first to fourth windings correspond to A, B, / A, / B in FIGS. 4 and 5. For example, the first winding = A, the second winding = B, the third winding = / A, the fourth winding = / B, or the first winding = B, the second winding = / A, 3 windings = / B, 4th winding = A,...

ST10: Preliminary operation (1)
Excitation of the first row in FIG. 10 is performed. In this example, the excitation time is the first time T1 = 35 unit times. For example, 1 unit time = 1.5 ms. Since the winding to be excited is not switched, the rotor does not rotate, but the rotor position is shifted in relation to the winding in which the rotor is excited (the first winding and the second winding in the example of FIG. 10). When you are, you may move a little to eliminate this gap.

ST11: Preliminary operation (2)
Excitations in the 2nd to 5th rows are performed. Each excitation time (second time) is 5 unit time, 8 unit time, 2 unit time, 5 unit time, and 2 unit time. Since the winding to be excited is switched, the rotor rotates. In the example of FIG. 10, the last excitation time (= 2 unit time) is shorter than the first excitation time (= 5 unit time), and the latter half is shorter than the first half on average (the average of the first half is 6.5 unit time, the average of the latter half is 3.5 unit time), so it can be said that the excitation time is gradually shortened.

  The first time of ST10 is about 8 times the average of the second time of ST11 and about 4.4 times the maximum value of the second time, which is significantly longer. The time of S10 is longer than the entire time of ST11, and the ratio thereof is 35: 22 = 1.6: 1. Such a long time is necessary to perform the holding firmly in ST10.

  In ST11, it is desirable to excite one or two windings in order from the initial position, with one of the windings excited in ST10 (first winding or second winding) as the initial position. In FIG. 10, this is the case.

  The processes of ST10 and ST11 are performed at t0 to ta in FIG.

ST12: Rotation process related to the spinning drum effect The excitation in FIG. 11A and the excitation in FIG. 11B are repeated.

  In the period from ta to tb, the excitation shown in FIG. When the rotational speed reaches a desired speed (when excitation is performed for the time required to reach the desired speed), the excitation pattern is switched. The desired speed is, for example, the maximum rotation speed in the conventional spinning effect.

  In the period from tb to tc, the excitation shown in FIG. 11B is performed for a predetermined time.

  In the period from tc to td, the excitation shown in FIG. 11A is performed for a predetermined time.

  In the period from td to te, excitation in FIG. 11B is performed for a predetermined time.

  As shown in FIG. 11, the third time, which is the time for exciting one winding, is 2 unit times.

  In ST12, it is desirable to excite one or two windings in order from the end position, with the winding last excited in ST11 of the preliminary operation process as the end position in the period from ta to tb. For example, since the last excitation in FIG. 10 is the fourth winding, excitation is performed with the fourth winding and the first winding as end positions, and thereafter the excitation is switched according to FIG.

  In ST10 of FIG. 8, any two windings were excited. When the rotation control unit 1300 stores the position of the coil that is excited when the rotation is stopped immediately before the rotation effect, the winding to be excited in ST10 may be selected based on this.

  FIG. 12 shows the processing. ST101 to ST103 in FIG. 12 correspond to ST10 in FIG. The winding position that was energized at the time of the last stop of the spinning cylinder stored in the spinning cylinder control means 1300 is defined as a “winding position at the time of stop”.

ST101: Read the information of the coil that was energized when stopped.
Reads the winding position at the time of stop from memory.

ST102: Two windings for preliminary operation are determined based on the read information.
Two windings are selected based on the read winding position when stopped.

  When the winding position at the time of stop indicates one winding, for example, it is as follows.

  When A, A and B, or / B and A. In the case of A and B, the excitation pattern is as shown in FIG.

  When B, B and / A or A and B. In the case of B and / A, the excitation pattern is as shown in FIG.

  When / A, / A and / B, or B and / A. In the case of / A and / B, the excitation pattern is as shown in FIG.

  When / B, / B and A, or / A and / B. In the case of / B and A, the excitation pattern is as shown in FIG.

ST103: Exciting the selected two windings for a long time (first time T1).

  By executing the processing of FIG. 12, the rotor can be held more reliably.

  In the above description, a stepping motor including four windings A, B, / A, and / B has been described as an example. However, the embodiment of the present invention includes five or more windings. It can be applied to a stepping motor. For example, in a four-phase stepping motor having windings of A, B, C, and D, A and B (A, B, / A, / B in the case of unipolar), B and C, C and D, or D The above-described control can be applied to the winding A. The same applies to a six-phase stepping motor having windings A to F (for example, the first winding to the fourth winding correspond to ABCD and CDEF).

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
