In the example of FIG. 1, on the front of the pachislot machine 1, a main reel unit 30, a display 35 such as a liquid crystal panel, a medal insertion unit 11, a 1-bed button 201, a 3-bed button 203, a start lever 205, a left stop button 207L, a middle stop button 207M, and a right stop button 207R are disposed.
The display 35 is an example of the display unit in the present invention.

The main reel portion 30 has three reels (main reels) each having a plurality of types of symbols applied on the circumferential surface, and a reel rotation portion 17 (FIG. 2) that rotationally drives the three main reels. For example, 21 symbols are drawn side by side on the circumferential surface of each main reel. Three adjacent symbols of each reel are displayed through a transparent display window provided on the front of the pachislot machine. When all the main reels are stopped, nine symbols arranged in three rows and three columns are displayed on the display window.
The medal insertion unit 11 includes a mechanism for inserting and storing medals in a pachislot machine and a sensor for detecting the insertion of the medals.

The 1-bet button 201 and the 3-bet button 203 are input devices for setting the number of medals to be bet in one game. One medal is used for one game by pressing the one-bed button 201, and three medals are used for one game when the three-bed button 203 is pressed. When the bet number of medals is one, the presence or absence of a prize is determined according to the combination of symbols (progress) in one line in the horizontal direction in the middle of the three-row, three-column symbols described above. When the bet number of medals is 3, the combination of the symbols in the three lines in the upper, middle, and lower horizontal directions and the two lines in the lower right and upper left directions in the above-described three-row, three-column pattern The presence or absence of a prize is determined according to the eye). The line in which the presence or absence of a prize is determined in the arrangement of symbols in three rows and three columns is called a "winning line".
The number of medals to be bet in one game is not limited to the above example, and may be, for example, only one, or the player may freely select from among 1, 2, 3 or so. Further, the number of pay lines is also arbitrary. For example, only one middle line may be used, or five lines in the upper, middle, lower, and diagonal directions may be used.

  The start lever 205 is an input device for inputting an instruction to start the rotation of the main reel unit 30. When the start lever 205 is hit in a state where the medal is inserted from the medal insertion portion 11 and the number of medals is set by the single sheet bet button 201 or the three sheet bet button 203, rotation of the main reel in the main reel portion 30 starts .

  The left stop button 207L, the middle stop button 207M, and the right stop button 207R are input devices for inputting a stop instruction of each main reel of the main reel unit 30, and correspond to the instruction input unit in the present invention. When the left stop button 207 is pressed, the left main reel is stopped, when the middle stop button 207M is pressed, the center main reel is stopped, and when the right stop button 207R is pressed, the right main reel is stopped.

  The display 35 is a display device for displaying an effect video, and includes, for example, a liquid crystal display panel, an EL display panel, and the like. As described later, the display 35 displays an image in which a reel (virtual reel) for effect simulating the main reel rotates and stops, an animation image of a character or the like, and the like.

  The pachi-slot machine also has a touch sensor 33 for detecting an object (such as a player's finger or the like) on the screen of the display 35. The touch sensor 33 detects an object in a detection area covering the image display surface of the display 35, and generates data indicating the position of the detected object.

FIG. 2 is a view showing an example of the configuration of the pachi-slot machine 1 according to the present embodiment.
For example, as shown in FIG. 2, the pachi-slot machine 1 according to the present embodiment has a main control unit 3, a sub main control unit 5, and a sub sub control unit 7.

[Main control unit 3]
The main control unit 3 is a circuit block that generally controls the overall progress of the game, and includes, for example, a processor that executes processing in accordance with a program and a memory. The main control unit 3 sets, for example, the number of bet medals, starts to rotate the main reel according to the operation of the start lever 205, and determines the combination of symbols on the pay line of the main reel (lottery). A series of operations such as stopping the reel according to the result of the internal lottery, judging the winning result according to the appearance on the winning line, and paying out medals are controlled.

  In the example of FIG. 2, the main control unit 3 includes the medal insertion unit 11, the medal payout unit 13, the lottery unit 15, the reel rotation unit 17, and the operation button group 20 (201, 203, 205, 207L, 207M, 207R). Is connected. The display 35 and the speaker 37 are connected to the sub-sub control unit 7.

  The main control unit 3 monitors a medal insertion detection signal from the medal insertion unit 11 and records the number of medals stored for use in a game. When the start lever 205 is hit in a state where the appropriate number of medals are inserted in the medal insertion section 11 and the bet number of medals is set by the bet buttons (201, 203), the main control section 3 selects the lottery section 15 At the same time, the lottery of the main lottery is carried out to obtain the lottery, and the reel rotating unit 17 of the main reel unit 30 is controlled to start the rotation of the three main reels.

The lottery lottery unit 15 generates a random number according to the control of the main control unit 3, and performs a lottery based on the generated random number to determine a main lottery. The main lottery indicates one game use selected from among a plurality of predetermined game use by lottery. The gaming role is a role associated with giving a gaming value such as a medal, and mainly determines a combination of symbols on the pay line (progress). For example, a small winning combination in which medals are paid out for each game, a bonus combination in which medals are repeatedly paid out repeatedly in a plurality of games, and medals are inserted in games There is a role such as a replay role that becomes unnecessary. The lottery lottery unit 15 randomly selects one gaming combination as a main lottery from such a plurality of predetermined gaming combinations.
Note that, in the present embodiment, the gaming combination that the lottery lottery section 15 selects as a lottery result also includes a “off hand” in which no gaming value is given (a medal is not paid out).

  After the main control unit 3 starts the rotation of the main reel according to the instruction of the start lever 205, the reel rotation stop instruction is given by pressing any of the three reel stop buttons (207L, 207M, 207R). When input, the left, middle or right main reel corresponding to the pressed reel stop button is stopped.

  When stopping the main reel, the main control unit 3 stops the main reel stop position so that the main reel to be stopped is stopped at the symbol according to the game combination indicated by the main lot drawn by the lot drawing section 15 ( Control the rotation angle). For example, when the game combination indicated by the main lottery is a bonus combination, the main control unit 3 sets a predetermined sliding piece from the reference position of the reel (for example, the lower position in the display window of the main reel) when the reel stop button is pressed. If there is a bonus combination symbol within the number range, the reel rotation unit 17 is controlled (pull-in control) such that this symbol stops on the pay line. In addition, when the game combination indicated by the main lottery is a cancellation combination, the main control unit 3 applies the game value (to pay out the medals) at a position (rotation angle) at which the combination (progress) is not established. The reel rotation unit 17 is controlled (kick control) so that the rotation of the reel is stopped.

  When the three main reels are stopped in response to the operation of the player, the main control unit 3 determines the winning result based on the combination of the symbols on the winning line. The main control unit 3 controls the medal payout unit 13 so as to pay out the number of medals according to the number of predetermined medals on the pay line when the predetermined number of medals to be paid out is aligned with the pay line.

  Further, the main control unit 3 sequentially outputs to the sub main control unit 5 data (commands) relating to the progress of the game, such as start and stop of rotation of the main reel, lottery results of the lottery lottery unit 15, insertion and payout of medals, etc. .

  For example, when a medal is inserted in the medal insertion portion 11, the main control portion 3 is a sub main control portion showing data indicating the number of inserted medals, the number of medals stored in the medal insertion portion 11, and the like. Output to 5

  When the bet button (201, 203) is pressed, the main control unit 3 outputs data indicating the press to the sub main control unit 5.

  When the start lever 205 is hit with the bet number of medals set by the bet button (201, 203), the main control unit 3 indicates that the start lever 205 has been hit (the start of rotation of the main reel) The data indicating the operation is output to the sub main control unit 5.

  When the lottery unit 15 performs a lottery of the main lottery in response to the start lever 205 being hit, the main control unit 3 subdivides the data (main lottery data) indicating the main lottery that the lottery unit 15 has drawn. Output to the main control unit 5.

  When the reel stop button (207L, 207M, 207R) is pressed while any of the main reels is rotating in the main reel unit 30, the main control unit 3 confirms that the corresponding reel stop button is pressed. The data (data indicating the rotation stop operation of the corresponding main reel) is output to the sub main control unit 5. Further, the main control unit 3 outputs, to the sub-main control unit 5, data on a symbol (stop symbol) indicated by the main reel stopped by the pull-in control or the kicking control.

  When the stop symbols of the three main reels are determined, the main control unit 3 outputs to the sub main control unit 5 data of the winning result indicated by the combination of the symbols on the pay line (progress). Further, when medals are paid out from the medal payout unit 13 according to the winning result, the main control unit 3 outputs data indicating the number of medals paid out to the sub main control unit 5.

[Sub main control unit 5]
Next, the sub main control unit 5 will be described.
The sub main control unit 5 is a circuit block which inputs data (command) relating to the progress of the game from the main control unit 3 and determines the contents of the effect in the effect section (display 35, speaker 37, etc.) according to the input data. For example, it is configured to include a processor that executes processing in accordance with a program and a memory.

  The sub main control unit 5 selects one effect pattern from a plurality of predetermined effect patterns according to the main lot data output from the main control unit 3. Then, every time the sub main control unit 5 inputs data relating to the progress of the game from the main control unit 3, the sub main control unit 5 designates the contents of the effect (the image of the display 35 and the sound of the speaker 37) based on the determined effect pattern. Data is generated and output to the sub-sub control unit 7.

For example, the sub main control unit 5 is data serving as a trigger for outputting an effect in data relating to game progression input from the main control unit 3, and data regarding the content of an effect to be output according to this data And a plurality of trigger tables associated with each other are stored in the storage device.
When the main lottery data is input from the main control unit 3, the sub main control unit 5 selects one trigger table from a plurality of trigger tables stored in the storage device according to the gaming combination indicated by the main lottery data. . Then, whenever the sub main control unit 5 inputs data relating to the progress of the game from the main control unit 3, the sub main control unit 5 refers to the selected trigger table to generate data for designating the contents of the effect, and the sub sub control unit 7 Output.

  Furthermore, when the sub main control unit 5 detects an object (such as a player's hand or the like) near the screen of the display 35 by the touch sensor 33 and data indicating the position is generated, the object is detected based on the generated data. The coordinate data indicating the position of is acquired, and information on the state of the object such as whether or not a plurality of objects are detected near the screen, the movement distance of the object per predetermined time, the movement direction of the object, etc. is acquired. When the information regarding the position or state of the object is obtained based on the input data from the touch sensor 33, the sub main control unit 5 triggers the content of the effect to be output as a trigger for obtaining the information. And the data specifying the content of the determined effect is generated and output to the sub-sub control unit 7.

  FIG. 3 is a functional block diagram of the sub main control unit.

The sub main control unit 5 indicates that the main lottery is displayed when data relating to the progress of the game is input from the main control unit 3 or when coordinate data etc. of an object in the vicinity of the screen is obtained based on the detection output of the touch sensor 33. With reference to the effect pattern (trigger table) determined according to the game use role, data (command) for specifying the effect contents to be output as these data as a trigger (trigger) is generated, and the sub-sub control unit 7 Output to
For example, the sub main control unit 5 outputs, to the sub sub control unit 7, data specifying an image such as animation to be displayed on the display 35, data specifying a sound to be reproduced by the speaker 37, and the like. Further, the sub main control unit 5 outputs, to the sub sub control unit 7, data related to control of a virtual reel to be displayed as a video on the display 35. Furthermore, the sub-main control unit 5 performs blinking control of the notification lamp 31 as part of the effect.

  When the sub-sub control unit 7 inputs data (command) specifying the contents of the effect from the sub main control unit 5, the display of an image such as animation on the display 35 or the sound effect in the speaker 37 according to the input data (command) Play and so on. In addition, when the sub main control unit 7 receives data relating to control of the virtual reel from the sub main control unit 5, it controls an image of the virtual reel to be displayed on the display 35 according to the input data. When the rotation of the virtual reel of the display 35 is stopped, the sub-sub control unit 7 outputs, to the sub main control unit 5, data (stop result data) related to the combination of the symbols of the stopped virtual reel (progress).

  When the sub main control unit 5 receives from the sub sub control unit 7 stop result data related to the outcome of the stopped virtual reel, the sub main control unit 5 changes the effect contents determined according to the main lot according to the stop result data. That is, the sub main control unit 5 selects a new trigger table from the plurality of trigger tables stored in the storage device according to the appearance of the stopped virtual reel.

  Examples of commands output from the sub main control unit 5 to the sub sub control unit 7 include a basic common display command (error, setting change, stop button request, command for setting confirmation), timing instruction command (main control unit 3 side) Commands related to the operation of, for example, bet, start of main reel rotation, commands for stopping left, middle and right main reels), medal related commands (credit number, input number, payout number related command), sound related commands (sound generation) And commands to control stop, virtual reel related commands (virtual reel rotation start instruction data, left virtual reel rotation stop instruction data, middle virtual reel rotation stop instruction data, right virtual reel rotation stop instruction data, for presentation) Combination data, random number data to select stop pattern Stop order data related to the stop order of reels, effect commands of different models (commands for managing different effects for different models), special operation commands (commands for external input for menu display, for example, external input button operation commands, touch panel operation There are commands (system commands) and system commands (a command to change stop reels of virtual reels, a command to enlarge reels, etc.). The sub-sub control unit 7 controls the screen display on the display 35 and the output of sound effects on the speaker 37 according to these commands.

  On the other hand, as commands output from the sub-sub control unit 7 to the sub-main control unit 5, for example, a command related to bi-directional communication (a system command for performing communication), a state command of effect of model type (result of effect , Command to issue what kind of state), virtual reel result command (for example, information on combination of symbols arranged in virtual reel, for example, command to send information on winning symbol combination and symbol combination established) is there.

  Here, data to be output from the sub main control unit 5 to the sub sub control unit 7 regarding control of the virtual reel of the display 35 (effect combination data and random number data, stop order determination data, virtual reel rotation start instruction data, virtual reel stop instruction Data) will be described in detail.

  The system storage unit 76 stores a program for executing a process in the processing unit 70, data used for the process, and data temporarily held in the process of the process. For example, the system storage unit 76 stores a table including data such as the number of sliding symbols used for control of the stop position of the virtual reel (pull-in control, kick control).

  The processing unit 70 is a circuit that controls the overall processing of the sub-sub control unit 7 and processes the video displayed on the display 35 and the sound output from the speaker 37 according to the instructions of the program stored in the system storage unit 76. I do.

The processing unit 70 displays, on the display 35, an image of a virtual reel in which a plurality of types of symbols are applied to the circumferential surface as in the main reel. For example, the processing unit 70 does not perform three-dimensional graphics processing including processing such as coordinate conversion / texture mapping as in the prior art, and the I-frame configuring rotating movie data and stopped movie data as in the prior art The virtual reels are rotated or stopped according to the virtual reel control data (virtual reel rotation start instruction data, virtual reel stop instruction data, etc.) input from the sub main control unit 5 using Is displayed on the display 35.
Here, the I frame is a frame that can be decoded without referring to the previous and subsequent frames.

  That is, when the processing unit 70 receives virtual reel rotation start instruction data from the sub main control unit 5, the virtual reel starts rotating from the stopped state and gradually increases its rotation speed, and the rotation speed reaches a predetermined maximum rotation speed. Then, an image rotating at the maximum rotational speed (that is, at a constant speed) is displayed on the display 35.

  Specifically, the processing unit 70 configures an image including virtual reels on the frame buffer 75 every predetermined frame period, and in parallel with this, the image configured on the frame buffer 75 includes predetermined frames. It is displayed on the display 35 as one frame every period.

  In constructing the image of the virtual reel, the processing unit 70 first calculates the rotation angle of the virtual reel for each frame. For example, when the virtual reel is stopped, the processing unit 70 keeps the rotation angle of the virtual reel constant even when the frame is switched, and when the virtual reel is rotated, the rotation angle changes every time the frame is switched. Let In addition, when the rotation speed is accelerating immediately after the start of rotation, the processing unit 70 calculates the rotation angle so that the change amount of the angle becomes larger each time the frame is switched. When the rotation speed becomes constant at a predetermined maximum rotation speed, the processing unit 70 calculates the rotation angle such that the amount of change in angle at the time of frame switching is kept constant.

  When the rotation angle of the virtual reel is obtained, the processing unit 70 positions the plurality of types of symbols on the surface based on the image data of the plurality of types of symbols stored in the video / sound storage unit 74 and the rotation angle. An image of the reel body (left, middle, right) is generated and written to the frame buffer 75.

  When virtual reel stop instruction data on the left, center or right is inputted from the sub main control unit 5 while the virtual reel rotates at a constant speed, the processing unit 70 corresponds to the virtual reel on the left, center or right. The display 35 displays an image at which the rotation of the image is stopped.

When stopping the virtual reel, the processing unit 70 selects the rotation angle (the position of the symbol) of the virtual reel at the timing when the virtual reel stop instruction data is input and the stop pattern specified by the effect combination data and the random number data. Based on the rotation angle at which the virtual reel stops (the position of the symbol) is controlled.
That is, when the processing unit 70 receives virtual reel stop instruction data from the sub main control unit 5 while the rotating image of the virtual reel is displayed, the virtual reel stop virtual at the timing when the virtual reel stop instruction data is input. Based on the rotation angle of the reel (the position of the symbol) and the stop pattern specified by the effect combination data and random number data input from the sub main control unit 5, the rotation angle for stopping the virtual reel to be stopped (symbol Position is determined, and an image in which the virtual reel to be stopped is stopped is displayed on the display 35 at the rotation angle (the position of the symbol).

For example, based on the effect combination data and random number data input from the sub main control unit 5, the processing unit 70 specifies a specific table from a plurality of virtual reel stop position control tables stored in advance in the system storage unit 76. select. This table includes, for example, data that associates the rotation angle (the position of the symbol) of the virtual reel at the timing when the virtual reel stop instruction data is input and the rotation angle at which the rotation of the virtual reel stops. In the data registered in the table, the symbol which the stop pattern specified by the effect combination data and the random number data allows is stopped on the pay line (draw-in control), and the symbol prohibited by the effect combination is not stopped on the pay line It is adjusted in advance as (kick-off control).
When virtual reel stop instruction data is input from the sub main control unit 5, the processing unit 70 refers to the above table selected based on the effect combination data and the random number data, and the rotation angle at which the rotation of the virtual reel is stopped. The position of the symbol is determined, and an image in which the rotation of the virtual reel is stopped at the determined rotation angle is displayed on the display 35.

The processing unit 70 displays the sub reels using movie data.
The processing unit 70 switches and uses rotating movie data for each of the three sub reels and stopped movie data for each of the three sub reels to realize a rotating and stopping video. The six movie data are loopable movie data in which the head and the end are seamlessly connected.
In the present embodiment, the rotating movie data is configured of a plurality of frames for displaying a rotating image for at least one rotation of the corresponding virtual reel. Also, the in-stop movie data is configured of a plurality of frames for displaying the in-stop video for at least one rotation of the corresponding virtual reel.

The processing unit 70 also performs index value calculation processing for calculating a frame value which is an index value used to specify a frame to be drawn next based on the rotation speed of the virtual reel.
Further, the processing unit 70 determines whether the rotation state of the virtual reel is in a blur state (first state) exceeding a predetermined rotation speed (blur speed) or in a non-blur state (second state) not exceeding the predetermined rotation speed (blur speed). The rotational speed determination process is performed.

Further, when it is determined that the processing unit 70 is in the blur state, the processing unit 70 decodes the I frame specified based on the frame value calculated by the index value calculation processing among the I frames configuring the movie data during rotation. And perform a first drawing process to draw.
Further, when it is determined that the processing unit 70 is in the non-blurring state, the processing unit 70 determines, of the I frames constituting the in-stop movie data, the I frame specified based on the frame value calculated by the index value calculation process. A second drawing process of decoding and drawing is performed.

Hereinafter, the bound process of step ST34 shown in FIG. 7 will be described with reference to FIG.
In FIG. 11, the bound angle is used to express a sway by adding it to the rotation angle. The bounding process is a process of calculating the bounding angle and the bounding frame for expressing the swing of the reel by adding to the movie frame after stopping.

  The processing unit 70 sequentially reduces the rotational speed when the rotational speed of the virtual reel is outside the predetermined range including the rotational stop in the bound process, and reduces the bound angle by a size according to the rotational speed. Processing is performed to determine the next frame to be subjected to drawing processing from movie data in accordance with the bound angle.

The processing unit 70 determines whether the rotation angle of the virtual reel is less than a predetermined first threshold (for example, 0.5) (ST81), and in the case of a positive determination, the bound angle is 0 It is determined whether or not it is less than (ST82), and in the case of a positive determination, a value obtained by subtracting the bound width from the rotation angle is set as a new rotation angle (ST83), and the process proceeds to step ST88.
On the other hand, if the determination in step ST82 is negative, the processing unit 70 proceeds to step ST88.
Further, in the case of a negative determination in step ST81, the processing unit 70 proceeds to step ST84.

The processing unit 70 determines whether the rotation angle of the virtual reel is less than a predetermined second threshold (for example, -0.5) having the opposite sign to the first threshold (ST84). In the case of positive determination, it is determined whether the bound angle exceeds 0 (ST 86), and in the case of positive determination, a value obtained by subtracting the bound width from the rotation angle is set as a new rotation angle (ST 87). The process proceeds to step ST88.
On the other hand, in the case of a negative determination in step ST86, the processing unit 70 proceeds to step ST88.
Further, in the case of a negative determination in step ST84, the processing unit 70 sets the rotational speed to "0", sets the state STS to "in idle", and proceeds to step ST88.

In step ST88, the processing unit 70 sets "bounce angle-rotational speed / velocity scale value" as a new bounce angle.

On the other hand, in the case of a negative determination, the processing unit 70 sets “maximum frame * bound angle / 360” as a new bound frame value (ST90).
Here, the bound frame value is “a value obtained by calculating the width of a frame value corresponding to the bound angle when the maximum frame is 360 degrees”.
