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 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, 2010-197142, A In the case where error notification based on another error command has already been performed, a predetermined priority order between the received error command and the error command 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). JP, 2010-207262, A When a reach is performed, it is memorized as a history of reach. At that time, it is described that when the reach number exceeding the limit number is to be stored, the reach with the lower priority order is deleted. When the creation of the liquid crystal image of the next frame is not completed even when the frame update time is reached, a so-called processing failure occurs in which the update time is delayed by that time. With respect to the image of the next frame in which the processing failure has occurred, the portion where the processing failure has occurred is recovered by not drawing a sheet having a low priority.

  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.

  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 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 (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 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 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.

  A command generation unit 20a generates a command for performing a predetermined effect based on a command from the main board 10 (specifically, reads a command from the ROM).

  The command generated by the command generation unit 20a indicates a command body (corresponding to a conventional command itself) for controlling the liquid crystal control board 200 and other peripheral boards 205 (device control board) in FIG. 5 and a group of the commands. Group identification information. 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 group 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 represents a group. A group is identification information predetermined for each of a plurality of commands. In the following description, it is assumed that three groups (first group, second group, and third group) 0001, 0002, and 0003 are designated in advance for each command. In addition, the number of three types of groups is an exemplification, and an arbitrary number of groups such as two types, four types, five types,... Can be set. Since the example of FIG. 7 is hexadecimal notation, the first part (left half, first half) of the command is 16 bits. A maximum of 16 groups can be defined by using one digit. Note that the number of bits and the number of digits of the first portion can be arbitrarily determined. If necessary, you can increase the number of groups that can be specified by increasing the number of bits and digits.

  Which group is assigned to a specific command is arbitrary. Hereinafter, explanation will be added by taking a liquid crystal command as an example.

  There are various types of image-related commands generated by the command generation unit 20a. For example, a command A for changing a part of a screen that has already been generated / displayed, such as changing a character image (inserting an image), a command B for newly generating the entire screen to change to a completely different screen, There is a command C for setting the default screen. If the group of commands for changing a part of the screen is 0001, the group of commands for newly generating the entire screen is 0002, and the group of commands for setting the default screen is 0003, the groups of commands A, B, and C are They are 0001, 0002, and 0003, respectively.

  In this way, commands can be grouped by paying attention to command functions. Thereby, even if the same command is deleted by the process described later, the influence on the production can be reduced. For example, since the commands of group = 0002 and 0003 both rewrite the entire screen, compatibility may occur in a scene such as a scene change. In such a case, when a command of group = 0002 is received, group = 0003 can be deleted.

  Note that commands having similar functions may be merged into a single unit, and a group may be assigned thereto. In the above example, the command B group and the command C group can be combined into one group = 0002. This is possible because both command B and command C update the entire screen.

  Or, conversely, the group may be subdivided by paying attention to the difference in function details. For example, regarding the command A for changing a part of the screen, the groups are classified into 0001a and 0001b according to the difference in the change position (for example, the left side or the right side of the screen) and the type of image to be inserted (for example, character X or character Y). Can be divided into

  If the number of groups is reduced, the number of commands stored in the buffer can be reduced, and buffer overflow can be reliably prevented, and the deterioration of the quality of production due to the transmission of a large number of commands can be more effectively prevented. be able to. On the other hand, detailed production becomes difficult due to the decrease in the number of groups. When emphasizing the quality of production, it is considered preferable to increase the number of groups within an allowable range.

  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 205 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 setting unit 20b according to the embodiment of the 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 205 (hereinafter “device control board”).

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

  2004 obtains the group identification information (hereinafter, “generated command group identification information”) of the command received by the command reception unit 2001, and compares it with the saved command group identification information obtained by the command search unit 2003. It is a group comparison part which identifies the group to delete based on a rule.

Reference numeral 2004a denotes an erasure rule storage unit that stores the predetermined rule. The stored rules are as follows, for example.
(Rule 1) When a command of the first group (0001) is received, an untransmitted command of the second group (0002) may be deleted.
(Rule 2) When a command of the second group (0002) is received, an untransmitted command of the third group (0003) may be deleted.
(Rule 3) When a command of the third group (0003) is received, an untransmitted command of the first group (0001) may be deleted.

  The above rules can be determined as appropriate. Any one or only two of the above rules 1 to 3 may be adopted.

  Referring to the example in which the group of commands for changing a part of the screen is 0001, the group of commands for newly generating the entire screen is 0002, and the group of commands for setting the default screen is 0003, the above rule 1 Corresponds to not updating the entire screen when a part of the screen is changed. Since the command of group = 0001 changes part of the screen, this rule 1 can be used.

  The rule 2 means that the default screen is not set when the screen is updated. Both can be said to perform almost the same function, and it is only necessary to make a new screen that is not the default screen.

In addition, once the screen is returned to the default, the meaningless group = 0001 can be deleted by adopting the above rule 3 (particularly, in order to return to the default screen, the image is inserted into the current screen). Etc.). In this case, since it is considered that group = 0002 is also unnecessary, two groups may be deleted at the same time. That is, the following rule 3 ′ is adopted instead of rule 3.
(Rule 3 ′) When a command of the third group (0003) is received, unsent commands of both the first group (0001) and the second group (0002) may be deleted.

  Further, although it is an example different from the above-mentioned example, the above (Rule 3 ′) is also applied when the group = 0001 is inserted into the image, the group = 0002 is changed in the background, and the group = 0003 is updated in the full screen. Can be adopted. Since the third group (0003) is an overwriting of the screen, the drawing by the command of another group is overwritten, so that the drawing is not presented to the player and has no meaning. Unnecessary commands can be deleted by the above (Rule 3 ').

In summary, for example, the rules are generally as follows.
(1) Delete a command of a specific group previously associated with a newly generated command group. This is a case where one of a plurality of commands is selected. For example, this is a case in which either the production α of the group A or the production β of the group B is executed alternatively.
For example, when the production α is “the character X in black clothes crosses the screen” and the production β is “the character X in yellow clothes crosses the screen”, the command of the production α and the command of the production β This is the case where either one is selected.
(2) When a newly generated command invalidates a command of a specific group (overwriting, updating immediately, etc., the presentation by the command is substantially presented to the player. Delete the command of the group.
For example, when the production γ is “displaying a black crow” and the production δ is “the background is dark night”, the production γ cannot be seen on the screen, so the command of the production γ is deleted. .
(3) When a newly generated command also fulfills the function of a command of a specific group (for example, there is upward compatibility), the command of the group is deleted.
For example, when the effect ε is “display the starry sky” and the effect φ is “the background is the night sky (you can see stars in a clear sky)”, the effect φ alone is sufficient, so the command for the effect ε is deleted. To do.
(4) When a newly generated command is substantially the same as a command of a specific group (eg, functionally the same), the command of the group is deleted.
For example, the production λ is “the owl flies and stops at the top of the tree”, and the production μ is “the owl flies and stops at the middle branch of the tree”. When there is no difference (when there is no such thing as notifying the presence or absence of a bonus or AT according to the position where the owl stops), one of the production commands is deleted.

  The above rules are realized, for example, by a program (combination of comparison command, conditional branch command, deletion execution command, etc.). Alternatively, it is also realized by a combination of logic circuits or a table (memory) that stores a truth table equivalent to the logic circuit. In such a case, it can be said that the erasure rule storage unit 2004a is a part of the memory used by the CPU.

  A command deletion unit 2005 receives the comparison result of the group comparison unit 2004 and deletes the command specified by the group comparison unit 2004 from the buffer 2002. Specifically, which command is deleted follows the above rules.

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

  FIG. 10 is a diagram for explaining the operation of the transmission command setting unit 20b and shows the contents of the buffer 2002. This figure shows a state in which commands (a) to (c) are stacked in order in the buffer. Commands are transmitted in order from the top (that is, they are transmitted in the order of (a) (b) (c)). The figure shows a state in which there are at least three groups and three commands of different groups are present in the buffer 2002 without being transmitted. (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, for example, (a) (b) (c) (note that the stacking order is not limited to this).

  FIG. 11 is an explanatory diagram of command deletion in the buffer 2002. FIG. 11 is almost the same as FIG. 10, except that the XXX of the command body is AAAA for convenience. This is done only to distinguish it from the added command BBBB. FIG. 11A shows that (d) is newly generated and the command 0x0002BBBB is added to the buffer 2002. There is no substantial difference between XXXXXX, AAAA, and BBBB in performing the processing according to the embodiment of the invention.

  FIG. 11B shows an example of the contents of the buffer 2002 after command deletion.

FIG. 9 is a process flowchart of the transmission command setting unit 20b according to the embodiment of the invention.
Next, the operation will be described with reference to the flowchart of FIG.

S10: A command to be transmitted is received.
The command receiving unit 2001 receives a command from the command generating unit 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 three untransmitted commands (a) to (c).

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

S12: The group of untransmitted commands in the buffer 2002 is confirmed.
The command search unit 2003 searches the buffer 2002 to acquire each command group. In the example of FIG. 11, for (a) to (c), the respective groups are 0001, 0002, and 0003.

S13: The group comparison unit 2004 identifies an erasable group based on the erasure rule.
In accordance with the rules of the erasure rule storage unit 2004a, based on the command group received in S10, whether there is an erasable group for the group acquired in S12, and if it is erasable, specify which command is to be erased ( For example, the address of the corresponding command in the buffer 2002 is acquired). In the example of FIG. 11A, since the newly generated command (d) group is 0002, it is assumed that group = 0003 is deleted according to the above-mentioned rule 2. That is, the command (c) is designated for deletion.

S14: The group comparison unit 2004 determines whether there is an erasable group.
A command corresponding to the group specified in S13 is searched. In the example of FIG. 11A, since the command (c) corresponds, the determination result is set to YES and the address of the command is acquired. If there is no corresponding, NO is determined and the process proceeds to S16.

S15: The command deletion unit 2005 deletes the command of the group specified in S13.
In the example of FIG. 11A, (c) is deleted. When there are a plurality of commands corresponding to (c), they are all deleted.

  Alternatively, a total of X commands may be deleted using a predetermined number of X as parameters. For example, if X = 4, delete up to 4 commands from the beginning (all of the commands received this time are not included and if the number of commands is less than 4), or up to 4 commands from the end Delete all commands if there are less than 4 commands received this time, or 2 commands counted from the beginning and 2 commands counted from the last (not including the command received this time, If there are less than 4 in total, delete all). If a plurality of groups are designated as deletion targets, X is the number of deletions for each group.

S16: The received command is registered in the buffer 2002 as a command to be transmitted.
There are two ways to register at this time.

(1) Add to the end of the buffer 2002. In most cases, a first-in first-out memory (FIFO) is used as the buffer 2002. In this case, it is a normal method to add the buffer 2002 at the end. In this case, the transmission order of the added command is last. According to this method, the state of the buffer after the processing of FIG. 9 is as shown in FIG.

(2) Write a newly generated command at the position of the deleted command. In other words, the newly generated command is overwritten (replaced) in the command of the same group. If the command to be deleted in FIG. 11A is (A), a new command (D) is written at this position. Then, the transmission order of the command (d) is second.

In order to explain the example of (1) above, the following commands (a) to (d) in FIG. 11 are considered.
In a scene where the current background is in a school classroom,
(A1) The hero stands up (stands up)
(I 1) The screen is on the way home (scene from walking out of the classroom with luggage)
(C) Update to default screen (represents the possibility that the previous screen display may be reset)
(D) Scene where the main character is at home

  In (A1) to (D1), when (c) is deleted and (D) is added as shown in FIG. 11, either (1) or (2) is used. Either one can be used because the same result is obtained.

  However, in the cases (a1) to (d1) above, when (b1) is deleted and (d1) is added, (a1) (c1) (d Even if the commands are executed in the order of 1), it is not unnatural to show that the main character gets up and goes home, but in the manner of (2) above, (a1) (d1) (c1 If the commands are executed in the order of), it will appear unnatural as if the main character just sits down and gets home.

  If you want to use the sense of incongruity effectively, such as when the protagonist's expression is unnatural, such as when he / she gets home, the expectation of bonuses and ART increases. The method of (2) above can also be adopted.

In order to explain the example of (2) above, the following commands (a) to (d) in FIG. 11 are considered.
In a scene where the current background is in a school classroom,
(A2) The hero stands with his luggage and leaves the classroom
(B) Scene where the main character enters the cram school from the cram school entrance and studies at the cram school
(C) Update to default screen (representing the possibility that the previous screen display may be reset)
(D2) The scene where the hero enters from the entrance and is at home

  In (A2) to (D2) above, when (D) is deleted and (D) is added as shown in FIG. 11, either (1) or (2) is used. Either one can be used because the same result is obtained.

  However, in cases (a2) to (d2) above, when (b2) is deleted and (d2) is added, (a2) (d2) (c) Even if the commands are executed in the order of 2), it is not unnatural to show that the main character leaves the classroom after leaving the seat, so the method of (2) above can be adopted.

  Of course, even if the commands are executed in the order of (A), (C), (E), and (E) in the manner of (1) above, the scene may change after the protagonist leaves the classroom after leaving the seat. Since it becomes a scene at home after displaying that there is no indication, the method of (2) is suitable when it is not unnatural, but it is not desired to give an impression that does not frustrate by developing the scene at an early stage. In addition, in the case of adopting the above (2), it is suggested that the scene may be changed by executing the command (c), but the command executed next to the command (c) The command for updating the entire screen (category 0002 or category 0003) may be prevented from being registered.

  However, the scene changes continuously ((b2) and (d2) occur consecutively (with (u2) in between, but it is thought that the scene changed even if (u2) was executed) In the case of using a sense of incongruity that effectively increases the expectation of bonuses and ART when a non-obtrusive performance is expressed, the method of (1) above can also be adopted. .

  Another processing example will be described. In FIG. 12, the contents of the buffer become as shown in FIG. 11B by the processing of FIG. 9, and then, as shown in FIG. 12A, a new command (e) is generated before the command (a) is transmitted. An example of processing in the case of

  In this case, since the group of the generated command (e) is 0001, the group = 0002 is deleted according to the rule 1 described above. Therefore, only two commands (A) and (O) are left in the buffer by the processing of FIG. 9 as shown in FIG. 11B.

  With the above processing, the commands in the buffer are deleted as appropriate, so the possibility of exceeding the capacity of the buffer is reduced.

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

  Note that the same group as the newly generated command may be deleted. In this case, only the newly generated command is present in the buffer for the group.

For reference, the case where the 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 be waiting when the operation is fast. 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.

  Further, buffer overflow may occur, and there is a demerit that the cost increases if the memory capacity is increased so as not to occur.

  On the other hand, according to the embodiment of the invention, the above disadvantageous situation does not occur.

  The above description has been given by taking the liquid crystal display device as an example for the sake of convenience, but can also be applied to commands for other devices. For example, for the arch lamp 130, the three areas of the left lamp (up, down, left and right, the direction when the player faces directly), the center (upper) lamp, and the right lamp are different commands. Can be divided into commands belonging to the left lamp category, commands belonging to the central lamp category, and commands belonging to the right lamp category. Can be applied. In addition, the speakers are also divided into four categories according to the arrangement of upper left, upper right, lower left, and lower right, and the embodiment of the present invention can be applied to this.

  Next, a modification according to the embodiment of the present invention will be described.

  FIG. 13 shows an example of commands according to the modification. As described above, the command according to the embodiment of the present invention is divided into the first part (left half, first half part) and the second part (right half, second half part), and these are integrated into one. Configure the command.

  The first part is, for example, 2 bytes. In the above description, the first digit is used to define the first to third groups. In the modification of FIG. 13A, the group to be deleted is directly specified using one of the remaining three digits. That is, the lowest digit of the first part indicates its own group, and the second digit from the bottom designates the deletion group. In FIG. 13B, a group to be deleted also from the third digit from the bottom is specified.

  Thus, by including the designation of the group to be deleted in the first part of the command, it becomes possible to freely designate the group to be deleted for each command. As a result, more various command deletion processes can be performed.

  14 and 15 show an operation flowchart according to this modification. The process in FIG. 14 is executed after, for example, S15 in FIG. 9 (the process jumps to S20 in FIG. 14 after S15 in FIG. 9, S16 is not executed). FIG. 15 executes only the processing according to this modification independently of FIG. 9.

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

S20: The group comparison unit 2004 checks whether there is a deletion group setting in the received command.
If the predetermined digit of the first part of the command is not 0 (zero), the deletion group is set (YES). If there is no deletion group setting (NO), the processing in FIG. 14 is terminated.

S21: The group comparison unit 2004 identifies a deletion group based on the received command.
This process is different from the process of S13 of FIG.
In the upper row of 0x0031XXXX in FIG. 13A, since group = 1 and deletion group = 3, the deletion group is the third group. Since 0x0032XXXX in the middle of FIGS. 13A and 13B has group = 2 and deletion group = 3, the deletion group is the third group. In the lower part of 0x0003XXXX in FIGS. 13A and 13B, group = 3, but no deletion group is specified. Therefore, this command is NO in S20, and the processing of S21 to S23 is not performed. Since 0x0231XXXX in the upper part of FIG. 13B is group = 1 and deletion group = 2 and 3, the deletion group is both the second group and the third group.

  In addition, you may make it perform the same process as S14 of FIG. 9 between S21 and S22.

S22: The command deletion unit 2005 deletes the command of the group specified in S21.
According to 0x0032XXXX in the middle of FIG. 13A, the third group is deleted by the process of FIG. Note that what is deleted in the process of FIG. 9 by the rule 2 is the third group, and in this case, the same result is obtained by the processes of FIG. 9 and FIG. On the other hand, according to 0x0031XXXX in the upper part of FIG. 13A, the third group is deleted by the process of FIG. 14 and the second group is deleted by the process of FIG. There will be only one group of commands. In this case, the command is further narrowed down by the processing of FIG.

S23: The received command is registered in the buffer 2002 as a command to be transmitted.
This is the same as S16 in FIG.
However, since the process of FIG. 14 is not performed for the command registered in the buffer 2002, the information related to the designation of the deletion group does not need to be stored in the buffer 2002 (the information can be stored).

  Since the processing of FIG. 15 is the same, the description thereof is omitted. In FIG. 15, the same reference numerals are given to the same equivalent parts as in FIGS. 9 and 14.

  The above description has been given by taking the liquid crystal display device as an example for the sake of convenience, but can also be applied to commands for other devices. For example, for the arch lamp 130, the three areas of the left lamp (up, down, left and right, the direction when the player faces directly), the center (upper) lamp, and the right lamp are different commands. Can be divided into commands belonging to the left lamp category, commands belonging to the central lamp category, and commands belonging to the right lamp category. Can be applied. In addition, the speakers are also divided into four categories according to the arrangement of upper left, upper right, lower left, and lower right, and the embodiment of the present invention can be applied to this.

  In the above description, the slot machine is taken as an example as a gaming machine, but the embodiment of the present invention is not limited to this, and can be applied to other gaming machines such as a pachinko machine.

  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.
