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 including a substrate (peripheral substrate, device control substrate) for controlling a display 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. 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, 2010-179142, A When the error notification based on other error commands has already been performed, a predetermined priority order between the received error command and the error command that is currently being executed for error notification If the received error command has a lower priority than the error command that is being executed for error notification, and if the notification based on the error command that is being executed is finished, the received error command is in the notification time , Start notification based on the reception error command, and continuously perform display notification based on the reception error command during the notification time (when the notification period has already ended at the end of notification of the error command with a higher priority) The error command received later is not notified).

  In order to display a predetermined image on the liquid crystal display device, a command is transmitted from the sub-board. When performing an effect by animation or the like, it is necessary to transmit a large number of commands successively one after another.

By the way, in such a situation, the screen of the liquid crystal display device may appear to flicker. This is because although a large number of commands are generated on the sub-board, it takes time to transmit the commands, and the screen may not be updated uniformly and appropriately in the liquid crystal display device. If the command transmission interval is long and the screen update interval is long, the movement seems to stop for a moment and it becomes awkward, and if multiple commands are sent at short intervals, the screen will be frequently updated and the screen will flicker .
The above can also occur for other devices related to production.

  Also, if the command generation rate is higher than the command transmission rate, the capacity of the buffer for temporarily storing the command becomes insufficient (buffer overflow), and thus a part of the command may be lost. If the lost command is important for the production, the production may become unnatural and the quality of the command may deteriorate.

  Therefore, the present invention has been made to improve the above situation, and an object of the present invention is to provide a gaming machine that can prevent the occurrence of screen flickering and avoid buffer overflow.

The present invention includes a main board that executes control related to a game including an internal lottery process, a sub board that receives a command from the main board and executes a process related to an effect, a device for performing the effect, and the sub In a gaming machine comprising a device control board that controls the device based on a command from the board,
The command includes a command main body for controlling the device control board and priority order identification information indicating a priority order of the command,
The sub-board is
A command generator for generating the command;
A buffer for storing the command to be transmitted to the device control board;
A command search unit that acquires the priority order identification information (hereinafter referred to as “stored command priority order identification information”) of the command stored in the buffer;
The priority order identification information (hereinafter referred to as “generated command priority order identification information”) of the command generated by the command generation unit is acquired and compared with the stored command priority order identification information acquired by the command search unit A priority comparison unit to
A command deletion unit that deletes the command related to the saved command priority identification information having a lower priority than the generated command priority identification information from the buffer;
A command registration unit for storing the command generated by the command generation unit in the buffer.

  The command deletion unit receives a specification of a priority to be deleted in advance, and deletes the command having a priority lower than the generated command priority identification information and having the specified priority from the buffer. You may do it.

Furthermore, a command counting unit for obtaining the number of commands stored in the buffer is provided,
The command search unit, the priority order comparison unit, and the command deletion unit may not operate when the number of commands by the command counting unit does not exceed a predetermined threshold.

As the predetermined threshold value, a first command number threshold value and a second command number threshold value different from the first command number threshold value are predetermined,
Corresponding to each of the first command number threshold and the second command number threshold, a first priority and a second priority to be deleted are predetermined,
When the command search unit, the priority order comparison unit, and the command deletion unit operate exceeding the first command number threshold, the command deletion unit has a lower priority than the generated command priority order identification information. And deleting the command of the first priority from the buffer,
When the command search unit, the priority order comparison unit, and the command deletion unit operate exceeding the second command number threshold, the command deletion unit has a lower priority than the generated command priority order identification information. The command having the second priority order may be deleted from the buffer.

Furthermore, a command frequency calculation unit for obtaining the command generation frequency by the command generation unit is provided,
The command search unit, the priority order comparison unit, and the command deletion unit may not operate when the frequency of occurrence of the command by the command frequency calculation unit does not exceed a predetermined threshold.

As the predetermined threshold, a first command reception frequency threshold and a second command reception frequency threshold different from the first command reception frequency threshold are predetermined,
Corresponding to each of the first command reception frequency threshold and the second command reception frequency threshold, a first priority and a second priority to be deleted are determined in advance,
When the command search unit, the priority order comparison unit, and the command deletion unit operate above the first command reception frequency threshold, the command deletion unit has a lower priority than the generated command priority order identification information. And deletes the command of the first priority from the buffer;
When the command search unit, the priority order comparison unit, and the command deletion unit operate above the second command reception frequency threshold, the command deletion unit has a lower priority than the generated command priority order identification information. In addition, the command having the second priority may be deleted from the buffer.

The threshold value may change according to a processing load on the sub-board.
Although the threshold value is given in advance, it can be changed according to the load status of the CPU of the sub-board. For example, when the CPU load is high, the threshold value is increased (which leads to a reduction in processing load), and when the CPU load is low, the threshold value is decreased (occurrence of the above-described problems can be effectively suppressed).

The command registration unit registers the command generated by the command generation unit in the buffer as a command to be transmitted last to the device control board regardless of the comparison result by the priority comparison unit.
By always adding the received command to the buffer, the received command is not lost. For example, even if the received command has the lowest priority, it is added to the end of the buffer, and thereafter, the command in the buffer is valid unless a command with a higher priority is received. According to this method, there is an advantage that the possibility that the latest command is lost is lower than the method of determining whether or not to write the received command according to the priority.

  According to the present invention, when a command with a high priority is received, a command with a low priority in the buffer is deleted, so that an overflow of the buffer can be prevented and the quality of production by sending a large number of commands can be prevented. A decrease can be prevented.

Embodiment 1 of the Invention
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.

  Further, a start switch 134 for starting a game is provided at the lower left of the game display unit 131, and three stop switches 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. A liquid crystal display device LCD is provided above 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 (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 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 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 established state, and the prescribed number of throws 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 a numerical value 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 (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 generation means 1050, 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 replay lottery states.

  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 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.

  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 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 switch 140 is operated by obtaining 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.

  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 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 boards are connected as shown in FIG. 5 (the display of the speaker board 201 is omitted). 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 subsequent to 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 shows a block diagram of the sub-board 20. This figure is a block diagram of a command transmission function of the sub-board 20, that is, a function of generating a command, registering the generated command in a transmission buffer, and transmitting a command in the buffer.

  Reference numeral 20 a denotes a command generation unit that generates a command for performing a predetermined effect based on a command from the main board 10.

  The command generated by the command generation unit 20a includes a command body (corresponding to a conventional command itself) for controlling the liquid crystal control board 200 and other peripheral boards 202 (device control board) in FIG. The priority order identification information shown is included. An example is shown in FIG.

  The command according to the embodiment of the present invention is divided into a first part (left half, first half part) and a second part (right half, second half part), and these constitute a single command. Yes. The first part (0001, 0002, 0003 in FIG. 7) corresponds to priority order identification information, and the second part (XXXX) corresponds to a command body. The second part (XXXX) shows the control contents of the device control board such as designating the display contents of the liquid crystal control board 200. In FIG. 7, all are XXX, but this means that an arbitrary command enters here, and actually different commands are entered. The content of the latter half (XXXX) is the same as the conventional one.

  Each first part indicates a priority order. In the example of FIG. 7, 0001 has a low priority, 0003 has a high priority, and 0002 is between these. The priority is a reference for the order in which the command is transmitted and executed, and the higher priority is assigned to a command (for example, the image of the main character on the screen) that is more important in terms of production. A low priority is assigned to a less important command (eg, background on the screen). The priority order is predetermined for each command.

  Except for the fact that priority order identification information is added to the command, the command generation itself is the same as in the case of a conventional gaming machine, and the description thereof is omitted.

  A transmission command setting unit 20b registers the command generated by the command generation unit 20a in a transmission buffer. This will be described in detail later (see FIG. 8 and the like).

  Reference numeral 20c denotes a command transmission unit 20c that transmits a command registered in the buffer to the liquid crystal control board 200 and other peripheral boards 202 in FIG. Since the command transmission itself is the same as that of the conventional gaming machine, the description thereof is omitted.

  FIG. 8 shows a block diagram of transmission command generation unit 20b according to Embodiment 1 of the present invention. More specifically, the apparatus shown in the figure is realized by a CPU provided on the sub-board 20 executing a program stored in advance in a memory (ROM).

  Reference numeral 2001 denotes a command receiving unit that receives a command generated by the command generating unit 20a.

  A buffer 2002 temporarily stores commands to be transmitted to the liquid crystal control board 200 and other peripheral boards 202 (hereinafter “device control board”).

  Reference numeral 2003 denotes a command search unit that acquires priority order identification information (hereinafter, “stored command priority order identification information”) of the stored command when even one command is stored in the buffer 2002.

  2004 obtains the priority order identification information (hereinafter, “generated command priority order identification information”) of the command received by the command receiving unit 2001 and compares it with the saved command priority order identification information obtained by the command search unit 2003. It is a comparison part.

  Reference numeral 2005 denotes a command deletion unit that receives a result of the comparison of the command search unit 2004 and deletes a command related to the saved command priority order identification information having a lower priority than the generated command priority order identification information from the buffer 2002.

  A command registration unit 2006 stores the command received by the command reception unit 2001 in the buffer 2002.

  FIG. 9 is a process flowchart of the transmission command generation unit 20b according to Embodiment 1 of the present invention.

  FIG. 10 is an explanatory diagram of the operation of the transmission command generation unit 20b and shows the contents of the buffer 2002. This figure shows a state in which commands (a) to (f) are stacked in order in the buffer. Commands are transmitted in order from the top (that is, transmitted in the order of (A) to (F)), and a newly received command is added to the lowest level. (F) is a command added (to be added) this time. This figure shows a state in which six commands are present in the buffer 2002 without being transmitted, including the latest command added this time. (A) is a command that is most recently stacked in the buffer 2002 and is transmitted first (at the next transmission opportunity). The stacking order is (a) (b) (c) (d) (e).

  Regarding priorities, there is a relationship of (a)> (b) = (c)> (d) = (e). Since the priority is lowered in the stack order, all the commands (a) to (e) are not deleted by the processing of FIG. 9 executed before receiving (f), but are stored in the buffer 2002. It remains. However, since (f) command with high priority is received, (b) to (v) are deleted as will be described later.

FIG. 11 is an explanatory diagram of command deletion in the buffer 2002.
FIG. 12 shows the contents of the buffer 2002 after command deletion.

  Next, the operation will be described with reference to the flowchart of FIG.

S10: A command to be transmitted is received.
A command is received from the command generator 20a.

S11: It is checked whether there is an untransmitted command in the buffer 2002.
The command search unit 2003 searches the buffer 2002 for a command. The command in the buffer 2002 is an untransmitted command. In the example of FIG. 10, there are five untransmitted commands (A) to (E).

  If there is an untransmitted command (YES), the processing after S12 is performed. If not (NO), the process of S16 is performed.

S12: The priority order of untransmitted commands in the buffer 2002 is confirmed.
The command search unit 2003 searches the buffer 2002 to obtain the priority order of each command. In the example of FIG. 10, (a) to (e) are 0003 (priority level = high), 0002,0002 (priority level = medium), and 0001,0001 (priority level = low), respectively.

S13: The priority of the untransmitted command is compared with the priority of the received command.
The priority comparison unit 2004 compares the priority of the command received in S10 with the priority acquired in S12. In the example of FIG. 10, (F) has a priority of 0003, and (A) to (E) have a lower priority than (F).

S14: The priority order comparison unit 2004 determines whether there is any unsent command that is lower than the priority order of the received command.

  In the example of FIG. 10, (A) to (E) correspond (YES), and the process proceeds to S15.

S15: The command deletion unit 2005 deletes an unsent command that is lower than the priority order of the received command.
In the example of FIG. 10, (A) to (E) are deleted. This is shown in FIG.

S16: The received command is registered in the buffer 2002 as a command to be transmitted last.
The command registration unit 2006 adds (f) to the bottom of the buffer. Then, as shown in FIG. 12, only two commands (A) and (F) remain in the buffer 2002.

  Through the above processing, a command related to control having a high priority, that is, control that must be executed can be transmitted quickly, and the quality of production is improved.

  According to the first embodiment of the invention, it is possible to suppress flickering of the screen and the like, to prevent deterioration in quality of production, and to avoid overflow of the buffer.

For reference, a case where a low priority command is not deleted will be described.
Since the timing (speed) of the stop operation of the slot machine of the slot machine is different for each person, a large number of commands may wait as shown in FIG. In such a case, the command may be transmitted at a very short interval. As a result, the command is executed in a short time on the received device control board, and the effect may be frequently switched. Such a situation makes it impossible for the player's eyes to follow, and the situation cannot be followed. It will give the impression of flickering.

  According to the first embodiment of the invention, such a situation does not occur.

There are also the following advantages.
According to the processing of FIG. 9, the received command is always added to the buffer 2002 regardless of its priority. Therefore, the received command is not deleted by the process when it is received. For this reason, commands are not lost carelessly. For example, even if the received command has the lowest priority, it is added to the end of the buffer 2002, and thereafter, the command in the buffer is valid unless a command with a higher priority is received. The process of FIG. 9 has an advantage that the possibility of losing the latest command is low as compared with the method of determining whether or not to write the received command according to its priority. This is very effective in improving the quality of the production, as it leads to surely executing the command generated after that when the frequency of generation of the command decreases after waiting for a large number of commands.
If the latest command is allowed to be lost, the received command may be a candidate for deletion.

When a command is received, only those with a predetermined priority or lower are deleted (for example, only those with priority = 1 (low) are deleted, or both priority = 1 (low) and 2 (medium) are deleted. The command may be selectively deleted according to the priority.
For example, the following processing is performed in S15 of FIG.

S15: The command deletion unit 2005 deletes an unsent command that has a priority lower than the priority of the received command and has a priority specified in advance.
It is assumed that a command having a priority order to be deleted is designated in advance (for example, designated for each gaming machine. As will be described later, the designated priority order is changed according to the number of commands and the frequency of command reception. You may do it).
For example, when it is specified that only those with priority = 1 (low) are deleted, only (D) and (E) in FIG. 10 are deleted.
For example, when it is specified that both priority = 1 (low) and 2 (medium) are to be deleted, (a) to (e) in FIG. 10 are deleted.

  In this way, it is possible to designate a command to be deleted, and fine adjustment is possible such that both a command having a high priority and a command having a priority next to the command are left.

Embodiment 2 of the Invention
In the first embodiment of the invention, each time a command is received, the priority is checked and compared, and the command is deleted according to the result. By assigning the processing capacity of the CPU to these processes, the load on the CPU increases, and the processing of other processes may be affected. On the other hand, if the capacity of the buffer 2002 is sufficiently large, it will not overflow even if the number of commands increases slightly. Therefore, the accumulation of commands may be allowed within a range in which the buffer 2002 does not overflow and no malfunction occurs. In this way, in addition to the same effects as those of the first embodiment, there is an effect that the load on the CPU can be reduced.

  FIG. 13 shows a block diagram of an apparatus according to Embodiment 2 of the invention. The same or corresponding parts as those in FIG. 8 are denoted by the same reference numerals, and the description thereof is omitted.

  Reference numeral 2007 denotes a command counting unit stored in the buffer 2002. The command counting unit 2007 instructs the command searching unit 2003 to perform an operation when the number of counted commands exceeds a threshold value. In other words, when the number of counted commands does not exceed the threshold, the command search unit 2003 to the command deletion unit 2005 do not operate.

  FIG. 14 is a process flowchart according to the second embodiment of the present invention. The same or corresponding parts as those in FIG. 9 are denoted by the same reference numerals, and the description thereof is omitted.

S11b: The command counting unit 2007 obtains the number of untransmitted commands.
When there is an untransmitted command in the buffer 2002, the number is obtained. In the example of FIG. 10, there are five commands (A) to (E) ((F) is excluded because it is a command to be added this time).

S11c: The command counting unit 2007 determines whether or not the number of untransmitted commands exceeds a predetermined threshold.
Although the threshold value is given in advance, it can be changed according to the load condition of the CPU of the sub-board 20. For example, when the CPU load is high, the threshold value is increased (the probability that the processes of S12 to S15 are performed is reduced, which reduces the processing load), and when the CPU load is low, the threshold value is decreased (processing load). In this respect, it is acceptable to increase the probability of performing the processing of S12 to S15).
When emphasizing on reducing the number of unsent commands, on the contrary, the threshold value may be lowered when the CPU load is high, and the threshold value may be raised when the CPU load is low.
For example, if the threshold value is 5, and (the number of untransmitted commands) ≧ (threshold value), if YES in S11c, the processing of S12 to S15 is executed in the example of FIG.

  According to the second embodiment of the invention, there is an effect that the load on the CPU can be further reduced.

Note that the priority order to be deleted may be changed according to the number of unsent commands. For example, when the number of unsent commands is large, many priorities are targeted for deletion (for example, both priority = 1 (low) and 2 (medium) are deleted), and when the number of unsent commands is small. A low priority is selected as a deletion target (for example, only those with priority = 1 (low) are deleted). You may make it delete a command selectively according to the number of unsent commands.
For example, the following processing is performed in S11c and S15 of FIG.

S11c: The command counting unit 2007 determines whether or not the number of untransmitted commands exceeds a predetermined threshold.
For example, the first command number threshold (for example, 3) is used when the CPU load is low, and the second command number threshold (for example, 5) is used when the CPU load is high.

S15: The command deletion unit 2005 deletes an unsent command that has a priority lower than the priority of the received command and has a specified priority.
For example, with respect to the first command number threshold (for example, 3) and the second command number threshold (for example, 5), the first priority to be deleted (for example, deletion of only those with priority = 1 (low)) and The second priority order (for example, priority = 1 (low) and 2 (medium) are deleted) is predetermined.
When the first command number threshold is met, the first priority command is deleted, and when the second command number threshold is met, the second priority command is deleted.

  In this way, it is possible to specify the priority order to be deleted by changing the priority order to be deleted according to the number of unsent commands, and when the number of commands is small, the command with the highest priority is followed by the command. Fine adjustment is possible, such as leaving both commands of priority.

Embodiment 3 of the Invention
In the second embodiment of the invention, the process of checking and comparing the priorities according to the number of untransmitted commands in the buffer 2002 and deleting the commands according to the result is turned on / off. In addition, the processing can be turned on / off according to the frequency of command reception.

  Assuming that the transmission frequency of commands from the buffer 2002 to the device control board is substantially constant, the number of untransmitted commands accumulated in the buffer 2002 is generally determined by the reception frequency of commands. Therefore, when the command reception frequency exceeds the threshold, the priority order is confirmed and compared, and the command is deleted according to the result.

  FIG. 15 shows a block diagram of an apparatus according to Embodiment 2 of the invention. 8 that are the same as or equivalent to the elements in FIG.

Reference numeral 2008 denotes a command frequency calculation unit that calculates a command reception frequency. For example, the command frequency calculation unit 2008 performs one of the following (1) and (2).
(1) The number of command receptions is counted, and the number of command receptions per unit time is defined as the reception frequency.
(2) A timer (not shown) is activated when a command is received, and the value of the timer when this command is received next (this value corresponds to the command reception interval) is used as the reception frequency. In this case, S10c of FIG. 16 described later determines that “the reception frequency (command reception interval) has fallen below the threshold”. Alternatively, the inverse of (command reception interval) is used as the reception frequency (corresponding to the command reception frequency). In this case, S10c in FIG. 16 may remain the process that “the reception frequency has exceeded the threshold”.

  The command frequency calculation unit 2008 instructs the command search unit 2003 to operate when the reception frequency exceeds the threshold. In other words, when the reception frequency does not exceed the threshold, the command search unit 2003 to the command deletion unit 2005 do not operate.

  FIG. 16 is a process flowchart according to the second embodiment of the present invention. The same or corresponding parts as those in FIG. 9 are denoted by the same reference numerals, and the description thereof is omitted.

S10b: A command reception frequency is obtained.
The command frequency calculation unit 2008 obtains the reception frequency by the method (1) or (2). In addition, you may make it obtain | require by both methods of (1) (2).

S10c: It is determined whether the reception frequency exceeds a predetermined threshold.
Although the threshold value is given in advance, it can be changed according to the load condition of the CPU of the sub-board 20. For example, when the CPU load is high, the threshold value is increased (the probability that the processes of S12 to S15 are performed is reduced, which reduces the processing load), and when the CPU load is low, the threshold value is decreased (processing load). In this respect, it is acceptable to increase the probability of performing the processing of S12 to S15).
When emphasizing on reducing the number of unsent commands, on the contrary, the threshold value may be lowered when the CPU load is high, and the threshold value may be raised when the CPU load is low.

  The third embodiment of the present invention has the same effect as the second embodiment of the present invention.

  Furthermore, since the third embodiment of the invention does not require access to the buffer 2002 when determining whether to skip the processing of S12 to S15, there is no access conflict with the command transmission unit 20c (command transmission unit 20c). Does not interfere with access by For this reason, it can be expected that the command transmission frequency of the command transmission unit 20c can be increased and the overflow of the buffer 2002 is less likely to occur.

The priority order to be deleted may be changed according to the command reception frequency. For example, when the command reception frequency is high, many priorities are set as deletion targets (for example, both priority = 1 (low) and 2 (medium) are deleted), and when the command reception frequency is low, a low priority is set. It is a deletion target (for example, only those with priority = 1 (low) are deleted).
For example, the following processing is performed in S10c and S15 of FIG.

S10c: The command frequency calculation unit 2008 determines whether the reception frequency exceeds a predetermined threshold.
For example, the first command reception frequency threshold (for example, 3) is used when the CPU load is low, and the second command reception frequency threshold (for example, 5) is used when the CPU load is high.

S15: The command deletion unit 2005 deletes an unsent command that has a priority lower than the priority of the received command and has a specified priority.
For example, with respect to the first command reception frequency threshold (for example, 3) and the second command reception frequency threshold (for example, 5), only the first priority (for example, priority = 1 (low)) to be deleted is deleted. ) And the second priority order (for example, both priority = 1 (low) and 2 (medium) are deleted) are predetermined.
When the first command reception frequency threshold is met, the first priority command is deleted, and when the second command reception frequency threshold is met, the second priority command is deleted.

  In this way, by changing the priority order to be deleted according to the command reception frequency, it is possible to specify the priority order to be deleted. When the command reception frequency is low, the command with the highest priority and the priority next to it are given. Fine adjustments are possible, such as leaving both commands.

  Embodiment 1 of the above invention can be combined with either Embodiment 2 or 3 of the above invention. Alternatively, the first embodiment of the present invention can be combined with both the second and third embodiments of the present invention.

  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.
