Abstract

PROBLEM TO BE SOLVED: To provide a game machine capable of keeping constant a performance frequency by a sub board, even if the set value of a main board is different, without increasing the used amount of a memory.SOLUTION: A sub board comprises: a coefficient storage part 2003 for comparing a reference set value and a present set value and outputting, if the two values do not coincide, a predetermined coefficient on the basis of the present set value; and a performance frequency stabilization part 2004 for conducting a performance on the basis of the coefficient on a value number outputted from a performance lottery table on the basis of a winning combination received from a main board, to output an actual value number, so that the difference in the set value is adjusted with the coefficient. Even in the case where the winning probability is different for every setting, the performance frequency of the winning combination can be less varied and can be stabilized. One lottery table is used to cope with the plural set values so that a memory capacity can be prevented from increasing.

Description

  The present invention relates to a gaming machine such as a slot machine or a pachinko machine, and more particularly to a gaming machine equipped with an effect device such as a liquid crystal display device.

  2. Description of the Related Art Conventionally, a gaming machine (rotational gaming machine, slot machine) having a plurality of reels 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. Also, this type of gaming machine performs an internal lottery triggered by the player's rotation start operation and starts rotation of a plurality of reels in a mode according to the result of the internal lottery as a player's stop operation trigger. Control is performed to stop a plurality of reels. The game result is determined by the symbol combination displayed on the winning determination line in a state where the plurality of reels are stopped, and medals are paid out according to the game result.

  In the gaming machine, various effects are made to improve the interest of the game. For example, a decorative member, a monitor (screen display device, liquid crystal display device), a speaker, and an LED lamp are attached, and a visual effect, a video effect, a sound effect, a light effect, and the like are performed.

JP, 2011-004788, A In a game machine which produces an effect by a plurality of patterns, a plurality of effect patterns appear at an individual frequency as the contents of the effect at the time of occurrence of a specific event. On the other hand, when a specific condition different from the normal condition is satisfied, an equal ratio obtained by equalizing the selection ratio is applied. Thereby, a plurality of effect patterns appear at a uniform frequency. The appearance frequency can be changed for various performance patterns without increasing the data capacity required for control.

  Although details will be described later, a gaming machine such as a slot machine includes a main board including an internal lottery means for performing a predetermined lottery process, a sub board that receives a command from the main board and executes a process related to the presentation, and a sub board. And a device control board for controlling a device for producing an effect such as a liquid crystal display device.

  The sub-board selects an effect corresponding to the lottery result by the internal lottery means of the main board. That is, a lottery result (winning combination) is received from the main board, and one of a plurality of effects corresponding to the lottery is selected by lottery.

  The slot machine basically pays out medals as prizes when the symbols are arranged, but whether or not the symbols are arranged depends on the result of a lottery by an internal computer. Various prizes, such as big bonuses, regular bonuses, and small roles, also follow the results of internal computer lottery. This lottery is performed on the main board, but the contents of the lottery process can be changed within a predetermined range (hereinafter referred to as setting change), and the setting work is performed by the store in the hall where the gaming machine is installed Done. To change the setting, open the door of the gaming machine, turn on the setting key switch provided on the power supply unit, turn the power switch from off to on, enter the mode where the setting can be changed, and then press the setting change switch. This was done by setting a set value according to a predetermined operation procedure.

  The set value is stored in the main board, and based on this, one is selected from a plurality of lottery tables, and lottery is performed based on the selected lottery table. Therefore, the appearance probability of the winning combination changes according to the set value.

  However, the conventional lottery related to the production on the sub board is performed in the same way even if the setting values are different. The production frequency was changed.

  This problem will be described with reference to FIGS. 11 and 12. In addition, since the same code | symbol as what was shown by FIG.3, FIG6 and FIG.7 is attached | subjected about each element shown by these figures, please also refer to those description.

  Reference numeral 1201 in FIG. 11 denotes a lottery table used for lottery. Assuming that there are six setting values 1 to 6, the lottery table 1201 includes six tables: a setting value 1 lottery table 1201-1 to a setting value 6 lottery table 1201-6. These six lottery tables have different contents.

  A setting value storage unit 1202 stores a setting value for selecting one from a plurality of lottery tables 1201-1 to 1201-6.

  Reference numeral 1203 denotes a lottery table selection unit that selects one of a plurality of lottery tables 1201-1 to 1201-6 in accordance with the set value of the set value storage unit 1202.

  A lottery processing unit 1204 performs a lottery process based on the selected lottery table.

  An effect lottery unit 20 a performs an effect lottery on the sub-board 20.

  FIG. 12 shows a block diagram of the effect lottery means 20a.

  2001 is an effect lottery table that stores in advance the number of values corresponding to the winning combination obtained by the lottery processing of the internal lottery means 1200 of the main board 10 and outputs the number of values based on the winning combination received from the main board 10. .

  Reference numeral 2002 denotes an effect lottery processing unit that performs a lottery process related to effects based on the number of values output from the lottery table 2001.

  In addition, since the lottery process itself based on the number of values is publicly known, description of the process content is omitted.

  As can be seen from FIG. 12, the effect lottery means 20a does not receive the set value, and outputs the same lottery result (effect type) regardless of the set value.

  Here, it is assumed that the winning probability is determined based on the preset value A (A is any one of 1 to 6) in the effect lottery table 2001. Taking a bell (small role) as an example, there are five types of bell effects 1 to 5 as shown in FIG. As an example, if the random value used for the lottery is 15 bits, when the bell is won at the reference setting value (in other words, the winning combination input to the effect lottery means 20a is the bell), the bell effect 1 The probability that any one of ˜5 is selected is 500/32768.

  In the case where the reference set value is set, in the lottery of the main board 10, it is assumed that (bell winning probability of the reference set value) = 1/10.

  Under the above conditions, the production frequency by the lottery of the production lottery means 20a is (probability of selecting the bell productions 1 to 5) × (bell winning probability of the set value A) = (500/32768) × (1 / 10) = 50/32768.

  However, it is assumed that the set value is changed from A to B (B is any one of 1 to 6, where A ≠ B). As a result, for example, the probability by lottery of the main board 10 changes such that (bell winning probability of the current set value) = 1/9.

  The production frequency by the lottery of the production lottery means 20a at the set value B is (the probability that the bell productions 1 to 5 are selected) × (the bell winning probability of the setting value B) = (500/32768) × (1/9) ≈ 55.6 / 32768. This is different from the production frequency at the reference set value A (in this example, it is increased).

  Thus, in the conventional gaming machine, the production frequency has changed with the change of the set value.

  In order to make the production frequency constant even when the set values are different, it is only necessary to provide a plurality of lottery tables for each set value on the sub board as well as the main board. A corresponding memory area is required, and the amount of memory used increases. This causes an increase in cost and is not preferable.

  The present invention has been made to solve the above-described problems, and provides a gaming machine that can make the production frequency of the sub board constant even when the set value of the main board is different without increasing the amount of memory used. The purpose is to do.

The present invention provides a main board including an internal lottery means for performing a predetermined lottery process, a sub board for receiving a command from the main board and executing a process related to the stage, and a predetermined stage based on data from the sub board. In a gaming machine equipped with a directing device to perform,
The internal lottery means of the main board is:
A plurality of lottery tables each having different contents;
A set value storage unit for storing a set value for selecting one from the plurality of lottery tables;
A lottery table selection unit for selecting the lottery table according to the set value;
A lottery processing unit for performing a lottery process based on the selected lottery table,
The sub-board is
An effect lottery table that stores in advance the number of values corresponding to the winning combination obtained by the lottery process of the internal lottery means of the main board, and outputs the number of values based on the winning combination received from the main board,
A coefficient storage unit that outputs a predetermined coefficient based on the set value received from the main board (hereinafter referred to as “current set value”);
An operation is performed on the number of values output from the effect lottery table based on the winning combination received from the main board based on the coefficient output from the coefficient storage unit (value obtained as a result of the operation) Is expressed as “actual value number”), an effect frequency stabilizing unit that outputs the actual value number,
And an effect lottery processing unit that performs a lottery process related to the effect based on the actual number of values output from the effect frequency stabilizing unit.

For example, the coefficient storage unit stores, as the coefficient, a value calculated based on (winning probability at a reference setting value) / (winning probability at the current setting value) for each winning combination,
The effect frequency stabilization unit outputs a value calculated based on (the number of values output from the effect lottery table) × (the coefficient output from the coefficient storage unit) as the actual value number.

  According to this invention, the coefficient storage unit that outputs a predetermined coefficient based on the current set value to the sub-board, and the coefficient for the number of values output from the effect lottery table based on the winning combination received from the main board And a production frequency stabilization unit that outputs the actual number of values and adjusts the difference of the set values by the coefficient, so that a single lottery table is used to set a plurality of set values. It is possible to cope with this, and it is possible to stabilize and reduce the change in the effect frequency of the winning combination even if the winning probability differs for each setting while preventing an increase in memory capacity.

  FIG. 1 is a front view of the slot machine with the front door closed, and FIG. 2 is a front view of the slot machine with the front door opened 180 degrees.

  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.

  A start switch 134 for starting a game is provided at the lower left of the game display unit 131, and three stop buttons 140 are provided corresponding to the three spinning cylinders. A medal payout port 135 is provided at the center of the lower end of the front door. Above the game display unit 131, a liquid crystal display device LCD (effect device) is provided.

  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 (rotating cylinder) unit 203 including three rotating cylinders 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 (first to third drums) 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 the player can see the symbols of the rotating drums of the reel unit 203. A power supply unit 205 is provided on the left side of the hopper device 121.

  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 for performing an internal lottery in response to a player's operation, and performing processing (game processing) such as reel rotation / stop and medal payout. 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 in accordance with 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 is paid out from a bet switch BET, a start switch 134, a stop button 140, a reel unit (including a reel driving device) 203, a reel position detection circuit 71, a hopper driving unit 80, a hopper 81 and a hopper 81. A medal detection unit 82 for counting the number of medals (these constitute the hopper device 121 described above) is connected. A peripheral substrate (device control 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. The peripheral board is controlled by the sub-board 20 and produces effects mainly by video, light, and sound. In the following description, for the sake of convenience, the liquid crystal control substrate 200 and other peripheral substrates will be described separately.

  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 means 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 based on the fact that medals corresponding to the prescribed number of insertions have been inserted, A process of permitting the rotation start operation of the first reel to the third reel is performed. Note that the pressing operation of the start switch 134 is an opportunity to start rotation of the first reel to the third reel and an opportunity to execute the internal lottery. Also, a prescribed number of throws is set according to the gaming state, the prescribed number of throws is set to 3 in the normal state and the bonus establishment state, and the prescribed throw number 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 this embodiment, 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, the acquisition timing and the like are irregular. Includes a value that can 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 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 generation means 1100, and the winning determination result For example, a lottery flag setting process for setting a flag to that effect is performed (see FIG. 6 and its description).

  In the lottery table selection process, it is determined which lottery table is used for the internal lottery among a plurality of lottery tables stored in a storage means (ROM) (not shown). 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 replay lottery states.

  A set value is used to select which of a plurality of lottery tables. The set value is any one of 1 to 6, for example, and any one of six lottery tables stored in advance in the ROM of the main board 10 is selected corresponding to this numerical value.

  The set value can be set by opening the door of the gaming machine, turning on the setting key switch provided in the power supply unit 205, turning the power switch from off to on, and then entering the mode in which the setting can be changed, and then pressing the setting change switch. The predetermined operation procedure is set. The set value is stored in the main board 10.

  In the random number determination process, based on the start signal from the start switch 134, a random value (lottery random number) is obtained from the random number generating means 1100 for each game, and the obtained random number value is won by referring to the lottery table. Determine whether or not.

  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 the big bonus is won by internal lottery, the big bonus 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 a role other than the regular bonus and the big bonus (small role and replay) is used even in a game in which 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.

  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.

  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 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 about 1 / 7.3, and a replay winning probability of about 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 reel control means 1300 rotates the first to third reels by a stepping motor based on a start signal generated by the player pressing the start switch 134 (rotation start operation), and the first to third reels are driven. Control that permits the pressing operation (stop operation) of the three stop buttons 140 respectively corresponding to the rotating reels in a state in which the rotation speed of the motor reaches a predetermined speed (about 80 rpm: a rotation speed of about 80 rotations per minute). And a control to stop the first reel to the third reel, which are rotationally driven by the stepping motor, according to the lottery flag setting state (result of the internal lottery).

  In addition, the reel control means 1300 receives the reel stop signal 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 this, by stopping the supply of drive pulses (motor drive signals) to the stepping motor of the reel unit 203, control is performed to stop each of the first to third reels.

  That is, each time the three stop buttons 140 are pressed, the reel control means 1300 determines the reel stop position corresponding to the pressed button among the first to third reels. The reel is stopped at the stop position. Specifically, referring to a stop control table (not shown) stored in the storage means (ROM), the first reel according to the pressing timing, pressing order, etc. (stop operation mode) of the three stop buttons. The stop position of the third reel is determined, and the first reel to the third reel are stopped at the determined stop position.

  Here, in the stop control table, the position of the first reel to the third reel (press detection position) at the time when the stop button 140 is operated and the actual stop position (or the slip from the press detection position) of the first reel to the third reel. (Number of frames) is set. Depending on the setting state of the lottery flag, a stop control table for determining the stop positions of the first reel to the third reel may be prepared.

  In the gaming machine, the reel unit 203 includes a reel index (not shown) made of a photosensor, and the reel control means 1300 is based on a reference position signal detected by the reel index every time the reel rotates once. By determining the rotation angle (the number of rotation steps of the rotation axis of the step motor) from the reel reference position (the frame detected by the reel index), the current rotation state of the reel can be monitored. . That is, the main board 10 can obtain the position of the reel when the stop button 140 is operated by determining the rotation angle from the reference position of the reel.

  The reel control means 1300 performs so-called pull-in processing and kick-out processing as control for stopping the reel. The pull-in process is a control process for stopping the reel so that the symbol corresponding to the combination whose lottery flag is set to the winning state is stopped on the winning determination line (so that the winning combination can be won). It is. On the other hand, the kicking process means that the reel corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on the valid winning determination line (so that the non-winning combination cannot be won) This is a control process to be stopped. That is, in the gaming machine of the present embodiment, the lottery flag setting state, the stop button 140 pressing timing, the pressing order, and the stop position of the reels that have already stopped (types of display symbols) in order to realize the pull-in processing and kicking processing. ) Etc., the stop control table is set so that the stop position of each reel changes. 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 reel to the third reel so as not to stop.

  In the gaming machine of the present embodiment, the first to third reels are set to a control state in which the rotating reel corresponding to the pressed stop button is stopped within 190 ms from the time when the stop button 140 is pressed. ing. That is, in the stop control table for determining the stop position of each rotating reel, the number of frames required from when the stop button 140 is pressed until each reel stops is in the range of 0 to 4 frames (predetermined pull-in range). Is set in

  The winning determination means 1400 performs a process of determining whether or not a winning combination has been won based on the stop mode of the first reel to the third reel. Specifically, referring to the winning determination table stored in the storage means (ROM), the symbol combination displayed on the winning determination line when all of the first reel to the third reel are stopped, It is determined whether or not it 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.

  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 reels (not shown), and one stepping motor is attached to each of the three reels. 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. 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 reel of the slot machine. A plurality of windings constitute one phase. As the number of phases, for example, there are two (two phases), four (four phases), and five (five phases).

Next, game processing in the gaming machine will be described with reference to FIG.
Generally, in a gaming machine, one game is started from the insertion of medals (insertion of credits) until the end of payout (or until the increase in the number of credits is completed). There is a rule that it is not possible to proceed to the next game until one game is finished.

  First, when a prescribed number of medals are inserted, the start switch 134 is activated, and the processing of FIG. 4 is started.

  In step S1, the start switch 134 is turned on by operating the start switch 134. Then, the process proceeds to the next step S2.

  In step S2, a lottery process is performed by the main board 10. Then, the process proceeds to the next step S3.

  In step S3, the rotation of the first reel to the third reel starts. Then, the process proceeds to the next step S4.

  In step S4, when the stop button 140 is operated, the stop button 140 is turned ON. Then, the process proceeds to the next step S5.

  In step S5, rotation stop processing is performed on the reel corresponding to the pressed stop button 140 among the first to third reels. Then, the process proceeds to the next step S6.

  In step S6, it is determined whether or not the operation of the stop button 140 corresponding to the three reels has been performed. If it is determined that all three stop buttons 140 corresponding to the three reels have been operated, the process proceeds to the next step S7.

  In step S7, it is determined whether or not the winning symbols corresponding to the lottery flag are aligned on the effective winning line while the lottery flag is established, that is, whether or not the winning is confirmed. If it is determined that the winning is confirmed, the process proceeds to the next step S8. If the winning is not confirmed, no medals are paid out even if the lottery flag is established.

  In step S8, medals corresponding to winning symbols are paid out.

  The process from the insertion of the medal to the completion of the execution of step S8 is one game. When the standby process in step S8 ends, the process returns to the beginning of the flowchart. In other words, the next game is possible (transition to the next game).

  FIG. 5 is an explanatory diagram of the connection between the sub-board 20 and its peripheral board (device control board). As shown in FIG. 3, a liquid crystal control board 200, a speaker board 201, and an LED board 202 are connected to the sub board 20. These should be called peripheral substrates of the sub-substrate 20.

  The plurality of peripheral substrates are connected as shown in FIG. That is, a plurality of peripheral boards are connected to a common bus, and communicate with the sub board 20 through the bus. The signal flowing through the bus is a signal on two lines, a data line and a clock line, such as a parallel signal (for example, a signal transmitted by an 8-bit line) or a serial signal (for example, I2C (Inter-Integrated Circuit)). ). In the example of FIG. 5, the signal output from the sub-board 20 is returned to the sub-board 20, but this is an example, and the end opposite to the connection end is opened as in a general bus structure. Also good.

  Data is transmitted from the sub board 20 to the peripheral board by designating an address. For example, when data is sent to the liquid crystal control board 200 as a peripheral board, an address previously associated with the liquid crystal control board 200 is designated and the data is sent to the bus. When the liquid crystal control board 200 recognizes that the data is addressed to itself by the address, the liquid crystal control board 200 takes in the data following the address into the latch. A predetermined operation is performed according to the fetched data. If the fetched data is a command for transmitting data acquired or obtainable by the liquid crystal control board 200 to the sub-board 20, the data is sent to the sub-board 20 (after receiving predetermined data, it is determined in advance. Data can always be transmitted to the sub-board 20).

  FIG. 6 is a block diagram of the gaming machine according to the embodiment of the invention. Only parts necessary for explaining the operation of the embodiment of the present invention are shown, and other elements are omitted.

  1201 is a lottery table used for lottery. Assuming that there are six setting values 1 to 6, the lottery table 1201 includes six tables: a setting value 1 lottery table 1201-1 to a setting value 6 lottery table 1201-6. These six lottery tables have different contents.

  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.

  A setting value storage unit 1202 stores a setting value for selecting one from a plurality of lottery tables 1201-1 to 1201-6.

  Reference numeral 1203 denotes a lottery table selection unit that selects one of a plurality of lottery tables 1201-1 to 1201-6 in accordance with the set value of the set value storage unit 1202.

  A lottery processing unit 1204 performs a lottery process based on the selected lottery table.

  The lottery processing unit 1204 acquires a random number value (random number for lottery) from the random number generation unit 1100 for each game based on the start signal from the start switch 134, and the lottery table selection unit 1203 selects the acquired random number value. It is determined whether the winning combination is won with reference to the lottery table.

  An effect lottery unit 20 b performs an effect lottery on the sub-board 20. The effect lottery means 20b includes an effect frequency stabilizing means 20c for making the effect frequency constant (so as to be stabilized) even when the set value is changed. The effect frequency stabilizing unit 20c corresponds to the coefficient storage unit 2003 and the effect frequency stabilizing unit 2004 in FIG.

  FIG. 7 shows a block diagram of the effect lottery means 20b.

  2001 is an effect lottery table that stores in advance the number of values corresponding to the winning combination obtained by the lottery processing of the internal lottery means 1200 of the main board 10 and outputs the number of values based on the winning combination received from the main board 10. .

  2002 is an effect lottery processing unit that performs a lottery process related to effects based on the number of values corrected by the effect frequency stabilization unit 2004.

  In addition, since the lottery process itself based on the number of values is publicly known, description of the process content is omitted.

  2003 compares a set value serving as a predetermined reference with a set value received from the main board 10 (hereinafter referred to as “current set value”). When these do not match, a predetermined value is set based on the current set value. It is a coefficient memory | storage part which outputs the coefficient of.

  FIG. 8 is an explanatory diagram of the contents stored in the coefficient storage unit 2003. Coefficients c1 to c6 are stored corresponding to the set values 1 to 6, respectively. The coefficients c1 to c6 are for a predetermined winning combination, for example, a bell (small combination). FIG. 8 shows an example of one winning combination (bell).

  The coefficient is calculated for a predetermined winning combination based on (winning probability of a set value serving as a reference) / (winning probability of a set value other than the reference). For example, when setting value 1 is a reference setting value and setting value 2 is a setting value for which a coefficient is to be obtained, for the winning combination, coefficient c2 = (winning probability of setting value 1) / (setting value 2 Winning probability). When (the winning probability of the setting value 1 (reference)) = 1/10, (the winning probability of the setting value 2 (current)) = 1/9, the coefficient c2 = 1/10/10/9 = 9/10 Become.

  The coefficient storage unit 2003 compares the reference set value with the set value received from the main board 10 (hereinafter referred to as “current set value”), and outputs the coefficient only when these do not match (the coefficient is When output, the production frequency stabilization unit 2004 operates (see FIG. 10).

  It should be noted that the reference set value is compared with the current set value, and instead of outputting a coefficient only when they do not match, a coefficient (value is 1) is associated with the reference set value, The coefficient may be output uniformly without comparing the reference set value with the current set value.

  2004 performs an operation based on the coefficient output from the coefficient storage unit 2003 on the number of values output from the effect lottery table 2001 based on the winning combination received from the main board 10 (the value obtained as a result of the operation) Is expressed as “actual value number”), which is an effect frequency stabilization unit that outputs the actual value number.

  According to the gaming machines of FIGS. 6 and 7, the effect lottery means 20b performs correction according to the set value, so that the effect frequency is the same even if the set value changes.

  With reference to FIG. 9, the operation of the gaming machine of FIGS. 6 and 7 will be specifically described. Take the bell (small part) as an example.

  FIG. 9A shows an example of the effect lottery table 2001 in the bell win. There are five types of effects, bell effect 1 to bell effect 5, and the number of values is 100.

  It is assumed that (bell winning probability of reference setting value) = 1/10, (bell winning probability of current setting value) = 1/9. Then, from the above-described coefficient calculation formula, the coefficient = (small set winning probability of the reference set value) ÷ (small set win probability of the current set value) = 9/10. The coefficient storage unit 2003 outputs 9/10. This coefficient is common to the bell effects 1 to 6.

  The effect frequency stabilizing unit 2004 calculates the actual number of values = (number of output values of the effect lottery table 2001) × (coefficient). The effect lottery processing unit 2002 uses a value obtained by multiplying the number of values set in the effect lottery table 2001 by the coefficient calculated as described above as an “actual value number” for the lottery.

  The fact that the production frequency is constant (stabilized) by the processing of the production frequency stabilization unit 2004 will be described.

  It is assumed that the winning probability is determined based on a preset value A (for example, A = 1) in the effect lottery table 2001. In FIG. 9A, since the number of values for all five types of bell effects 1 to 5 is 100, the probability that one of the bell effects 1 to 5 wins in the effect lottery processing unit 2002 is the randomness used for the lottery. Assuming that the numerical value is 15 bits and no correction is made, 100 × 5/32768 = 500/32768.

  Assuming that the probability that the bell effects 1 to 5 are selected at the reference setting value is 500/32768 (coefficient = 1 or no correction is made), the probability of winning the bell at the reference setting value is Since it is 1/10, the production frequency at this time is (probability of selecting bell productions 1 to 5) × (bell winning probability). Therefore, the production frequency of the bell productions 1 to 5 at the reference setting value = 500/32768 × 1/10 = 50/32768 (same as the case where there is no processing of the production frequency stabilization unit 2004).

  Next, a current set value B (for example, B = 2) other than the set value A will be considered. At the current set value, the effect lottery processing unit 2002 performs the lottery based on the actual number of values = 90 corrected by the effect frequency stabilizing unit 2004 based on the coefficient = 9/10 output from the coefficient storage unit 2003. . The probability that the bell effects 1 to 5 are selected at the current set value is 90 × 5/32768 = 450/32768.

  The effect frequency at this time is (probability of selecting bell effects 1 to 5) × (bell winning probability) = 450/32768 × 1/9 = 50/32768. This is the same as the production frequency at the reference set value.

  Similarly, for other winning combinations, a coefficient is calculated from the winning setting probability of the reference setting value and the current setting value, and the same processing is performed.

  As described above, according to the embodiment of the invention, the production frequency of the reference set value and the current set value is the same. Therefore, even if the set value changes, the production frequency is the same (stabilized).

  FIG. 10 is a process flowchart according to the embodiment of the invention. FIG.

S10: The coefficient storage unit 2003 compares the current set value from the main board 10 with the reference set value.
If the two match, the process of FIG. 10 is terminated. If not, the process proceeds to S11.

S11: The coefficient storage unit 2003 acquires and outputs a coefficient based on the current set value.

S12: The effect lottery table 2001 acquires the number of values corresponding to the winning combination based on the winning combination from the main board 10.

S13: The production frequency stabilization unit 2004 multiplies the number of values from the production lottery table 2001 by the coefficient from the coefficient storage unit 2003.

S14: The production frequency stabilizing unit 2004 outputs the result of S13 as the actual number of values.
The effect lottery processing unit 2002 performs a lottery based on the actual number of values from the effect frequency stabilizing unit 2004. Since the lottery process is publicly known, a description thereof will be omitted.

  According to the embodiment of the invention, it is possible to eliminate a setting difference in performance frequency that has occurred in gaming machines having different winning probabilities for each setting. Since the same lottery table is used, an increase in memory capacity can be prevented.

  In the above description, a slot machine has been described as an example, but the embodiment of the present invention can also be applied to other gaming machines such as pachinko machines.

  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.
