The process to return to the state before power-off is executed using.

(Step S200)
Next, the main CPU 200a places a bet on the medal by operating the bet button 126 in a situation where a specified number of medals are inserted from the medal insertion unit 124 or a credit exceeding the specified number is stored. Then, the operation of the start switch 128 is awaited. Further, in response to the bet operation for medals, the main CPU 200a transmits a throw command indicating that the operation has been performed to the sub-control board 202. When the operation of the start switch 128 is detected, the process proceeds to the next step S300.

(Step S300)
Next, the main CPU 200a performs an internal lottery to determine one of a plurality of winning combinations and losers based on the first internal lottery random number generated by the random number generator 256 according to the operation of the start switch 128. Do. Further, in response to the operation of the start switch 128, the main CPU 200a transmits a start command indicating that the operation has been performed to the sub-control board 202.

  In the slot machine 100, a plurality of game states are provided when the game progresses, and a plurality of lottery tables corresponding to these game states and set values are stored in the main ROM 200b. The main CPU 200a selects a corresponding lottery table according to the current gaming state and setting value stored in the main RAM 200c, and the random number corresponds to any winning combination in the lottery table based on the selected lottery table. Judge whether to do.

  Here, the winning combination extracted from each lottery table includes a replay combination, a small combination, and a bonus combination. The state in which the symbol combinations corresponding to such winning combinations are aligned on the active line is called display (winning), and the state until winning the winning combination and displaying the symbol combination corresponding to the winning combination is displayed internally. It is called winning. Of the winning combinations, the replay combination is a combination in which a medal bet is not required for the next game when the symbol combination corresponding to the replay combination is displayed on the active line. The symbol combination corresponding to is displayed on the active line, so that a predetermined number of medals can be paid out. The bonus combination is a winning combination that can shift the gaming state from the normal gaming state to the BB (big bonus) gaming state by displaying the symbol combination corresponding to the bonus combination on the active line. . Here, the normal game state is a game state using a lottery table (normal game state lottery table) in which the winning probability of the small role is set so that the medal decreases as the game progresses in determining the winning combination. is there. On the other hand, the BB gaming state is a gaming state that uses a lottery table (BB gaming state lottery table) in which the winning probabilities of small combinations are set so that medals increase in determining the winning combination.

  The above-mentioned start command includes not only the operation of the start switch 128 but also the internal lottery result (winning combination), information on the gaming state, and the like.

(Step S400)
When the lottery process is completed as described above, the main CPU 200a then drives the stepping motor 262 to rotate the rotating reels 134a, 134b, and 134c. In this reel rotation process, if a predetermined time (for example, 4.1 seconds) has passed since the rotation start time of the rotary reels 134a, 134b, 134c in the previous one game, the predetermined time has passed. Otherwise, after a predetermined time elapses, the rotation reels 134a, 134b, 134c in the game are started to rotate, and when all of the rotation reels 134a, 134b, 134c are rotated at a constant speed, a stop button switch The operation of 130a, 130b, 130c is validated.

(Step S500)
Subsequently, when the main CPU 200a receives an operation of the stop button switches 130a, 130b, and 130c by the player while the stop button switches 130a, 130b, and 130c are activated, the main CPU 200a rotates the reels 134a, Each of 134b and 134c is stopped according to a predetermined stop control. Further, the main CPU 200a transmits a stop command indicating that the operation has been performed to the sub-control board 202 in response to the operation of the stop button switches 130a, 130b, and 130c.

(Step S600)
Next, the main CPU 200a determines the symbol combination displayed on the active line, and executes various processes required for turning on / off each flag, changing the gaming state, and replaying based on the determination result. And we will prepare for the next game. When the main CPU 200a determines that the symbol combination corresponding to the small combination is displayed on the active line, the main CPU 200a executes a payout process for paying out medals corresponding to the small combination. Further, the main CPU 200a transmits a winning command indicating that the medal payout process has been performed to the sub-control board 202.

(Processing of sub-control board 202)
Hereinafter, processing of the sub-control board 202 will be described, but here, processing related to the features of the present embodiment will be described in detail, and description of configurations irrelevant to the features of the present embodiment will be omitted.

  FIG. 9 is a flowchart showing the main process of the sub control board 202.

(Step S1000)
First, when the power is turned on, the sub CPU 202a initializes the sub RAM 202c and the like, and executes an initialization process for permitting an interrupt.

(Step S1001)
Next, the sub CPU 202a monitors the input of commands from the main control board 200.

(Step S1002)
Next, the sub CPU 202a analyzes a command received from the main control board 200 and executes various processes based on the received command. Hereinafter, the command reception process S1002 will be described in detail.

  FIG. 10 is a flowchart showing the command reception process of step S1002. In the command reception process, for example, an effect based on the winning combination determined in the lottery process S300 is executed.

(Step S1101)
In FIG. 10, first, the sub CPU 202a determines whether a command is received. As a result, if a command has not been received, the command reception process is terminated. If a command has been received, the process proceeds to step S1102.

(Step S1102)
If it is determined in step S1101 that a command has been received, the sub CPU 202a determines whether the received command is a start command. As a result, if it is a start command, the process proceeds to step S1103, and if it is not a start command, the process proceeds to step S1106.

(Step S1103)
If it is determined in step S1102 that the command is a start command, the sub CPU 202a refers to an effect lottery table (not shown) and determines an effect mode performed in the game.

(Step S1104)
Based on the effect mode determined in step S1103, the sub CPU 202a determines a symbol rotation liquid crystal command, a symbol rotation voice command, and a symbol rotation illumination command for starting the variable display of the liquid crystal symbol image, and determines the determined symbol. A rotation liquid crystal command or the like is transmitted to the liquid crystal control board 204 or the like.

(Step S1105)
Based on the effect mode determined in step S1103, the sub CPU 202a determines a registered symbol liquid crystal command for designating a liquid crystal symbol number (liquid crystal symbol image) to be stopped and displays the determined registered symbol liquid crystal command on the liquid crystal control board 204. Send to. In particular, in the registered symbol liquid crystal command of this embodiment, three liquid crystal symbol numbers (liquid crystal symbol images) in the left, middle, and right columns are designated. The number of liquid crystal symbol numbers (liquid crystal symbol images) specified by the registered symbol liquid crystal command is not limited to three.

(Step S1106)
If it is determined in step S1102 that a start command has not been received, the sub CPU 202a determines whether the received command is a stop command. As a result, if it is a stop command, the process proceeds to step S1107, and if it is not a stop command, the process proceeds to step S1114.

(Step S1107)
If it is determined in step S1106 that the command is a stop command, the sub CPU 202a adds 1 to the stop counter in the sub RAM 202c and updates it. Here, the “stop counter” is for counting the number of times the stop switch 130 is pressed for one game, and the sub CPU 202a indicates the number of times the stop switch 130 is pressed by the stop counter. I can grasp it.

(Step S1108)
When the stop counter is updated by adding 1 in step S1107, the sub CPU 202a determines whether or not the stop counter is 1.

(Step S1109)
If it is determined in step S1108 that the stop counter is 1, the sub CPU 202a determines that the first pressing operation of the stop switch 130 has been performed, and the left symbol stop liquid crystal command, the left symbol stop voice command, and the left symbol stop The illumination command is determined, and the determined liquid crystal command or the like is transmitted to the liquid crystal control board 204.

(Step S1110)
If it is determined in step S1108 that the stop counter is not 1, the sub CPU 202a determines whether or not the stop counter is 2.

(Step S1111)
If it is determined in step S1110 that the stop counter is 2, the sub CPU 202a determines that the second press operation of the stop switch 130 has been performed, and the right symbol stop liquid crystal command, the right symbol stop voice command, and the right symbol stop The illumination command is determined, and the determined liquid crystal command or the like is transmitted to the liquid crystal control board 204.

(Step S1112)
If it is determined in step S1110 that the stop counter is not 2, the sub CPU 202a determines that the third pressing operation of the stop switch 130 has been performed, and the middle symbol stop liquid crystal command, the middle symbol stop voice command, and the middle symbol stop illumination. The command is determined, and the determined liquid crystal command or the like is transmitted to the liquid crystal control board 204.

(Step S1113)
When the middle symbol stop liquid crystal command or the like is transmitted to the liquid crystal control board 204 in step S1112, the sub CPU 202a clears the stop counter to zero.

(Step S1114)
If it is determined in step S1106 that a stop command has not been received, the sub CPU 202a executes processing corresponding to a command other than the start command and the stop command. For example, if it is an insertion command, a liquid crystal command for displaying the number of insertions and outputting an insertion sound is determined, and if it is a winning command, a liquid crystal command for displaying a winning combination and a medal payout number, etc. And various determined commands are transmitted to the liquid crystal control board 204 and the like.

(Processing of liquid crystal control board 204)
Hereinafter, processing of the liquid crystal control board 204 will be described, but here, processing related to the features of the present embodiment will be described in detail, and description of configurations irrelevant to the features of the present embodiment will be omitted.

  FIG. 11 is a flowchart showing the main process of the liquid crystal control board 204.

(Step S2100)
The liquid crystal CPU 204a monitors the input of a liquid crystal command from the sub-control board 202, and when a new liquid crystal command is received, performs a liquid crystal command reception process for preparing to perform image display control. The liquid crystal command reception process will be described later in detail with reference to FIG.

(Step S2200)
Then, the liquid crystal CPU 204a performs a structure analysis process on the display control table data. In the structure analysis process of the display control table data, image display control is performed based on the designated lower table data. Specifically, an image corresponding to the texture name is read from the liquid crystal ROM 204b in accordance with the lower table data designated in step S2105 or step S2109 described later, and the read image is set to the set X and Y coordinates. The image is drawn in the virtual display area 204e with the horizontal width and vertical width. If it is a wait timer value, it waits until the wait timer, and if there is a movement value, the image is moved and drawn by the movement value. If there is a call function name, the function is called.

(Step S2300)
The liquid crystal CPU 204a performs a symbol replacement process in order to update the liquid crystal symbol number. The details of this symbol replacement process will be described later with reference to FIG.

(Step S2400)
The liquid crystal CPU 204a performs a VSYNC interrupt wait process in order to update (synchronize) an image frame on the liquid crystal display unit 138. In this VSYNC interrupt wait process, the process waits until a VSYNC signal (vertical synchronization signal) is input from an oscillator (not shown) provided in the liquid crystal control board 204. When the VSYNC signal (vertical synchronization signal) is input, the wait timer value is updated.

  In the present embodiment, assuming that the generation period of the VSYNC signal is set to 30 ms, the wait timer value is updated every 30 ms. The generation period of the VSYNC signal is not limited to 30 ms, and may be configured with 1/60 s (about 16.6 ms) or 1/30 s (about 33.3 ms). Furthermore, it is not limited to waiting until the VSYNC signal is input once, but may be configured to wait until the VSYNC signal is input a predetermined number of times.

(Step S2500)
The liquid crystal CPU 204a performs character display processing in order to display an image on the liquid crystal display unit 138. In this character display process, image data (for example, RGB signals) of an image drawn in the image display area 204f of the VRAM 204d is generated, and the generated image data is output to the liquid crystal display unit 138.

  FIG. 12 is a flowchart showing the liquid crystal command reception process in step S2100.

(Step S2101)
In FIG. 12, first, the liquid crystal CPU 204a determines whether a liquid crystal command has been received. As a result, if a liquid crystal command has not been received, the liquid crystal command reception process is terminated. If a liquid crystal command has been received, the process proceeds to step S2102.

(Step S2102)
If it is determined in step S2101 that a liquid crystal command is received, the liquid crystal CPU 204a determines whether the received liquid crystal command is a registered symbol liquid crystal command. As a result, if it is a registered symbol liquid crystal command, the process proceeds to step S2103, and if it is not a registered symbol liquid crystal command, the process proceeds to step S2104.

(Step S2103)
If it is determined in step S2102 that the command is a registered symbol liquid crystal command, the liquid crystal CPU 204a uses the liquid crystal symbol numbers of the left, middle, and right columns specified by the received registered symbol liquid crystal command as the first registered symbol. And stored in the first storage area in the liquid crystal RAM 204c.

(Step S2104)
If it is determined in step S2102 that it is not a registered symbol liquid crystal command, the liquid crystal CPU 204a determines whether the received liquid crystal command is a symbol rotation liquid crystal command. As a result, if it is a symbol rotation liquid crystal command, the process proceeds to step S2105, and if it is not a symbol rotation liquid crystal command, the process proceeds to step S2106.

(Step S2105)
If it is determined in step S2104 that the command is a symbol rotation liquid crystal command, the liquid crystal CPU 204a designates display control table data (lower table data). Specifically, first, from the upper table data as shown in FIG. 6 (a), the intermediate table data shown in FIG. 6 (b) for each of the intermediate table groups based on the received liquid crystal command. Is specified. Next, lower table data as shown in FIG. 7A is specified from the specified middle table data.

(Step S2106)
If it is determined in step S2104 that the command is not a symbol rotation liquid crystal command, the liquid crystal CPU 204a determines that the received liquid crystal command is one of the left symbol stop liquid crystal command, the right symbol stop liquid crystal command, and the middle symbol stop liquid crystal command. It is determined whether it is. As a result, if it is a symbol stop liquid crystal command, the process proceeds to step S2107, and if it is not a symbol stop liquid crystal command, the process proceeds to step S2110.

(Step S2107)
If it is determined in step S2106 that the command is a symbol stop liquid crystal command, the liquid crystal CPU 204a further determines whether or not the received liquid crystal command is a middle symbol stop liquid crystal command. As a result, if it is a middle symbol stop liquid crystal command, the process proceeds to step S2108, and if it is not a middle symbol stop liquid crystal command, the process proceeds to step S2109.

(Step S2108)
When it is determined in step S2107 that the command is a middle symbol stop liquid crystal command, the liquid crystal CPU 204a secondly registers the liquid crystal symbol numbers of the left, middle, and right columns stored in the first storage area in the liquid crystal RAM 204c. The liquid crystal symbol number indicating the symbol is also stored in the second storage area in the liquid crystal RAM 204c. That is, when the middle symbol stop liquid crystal command is received, the second registered symbol is updated to the first registered symbol designated by the registered symbol liquid crystal command.

  In this way, the same registered symbol is stored in different storage areas in the first storage area and the second storage area of the liquid crystal RAM 204c, as will be described later, when starting the variable display of the liquid crystal pattern image. When the liquid crystal symbol number (second registered symbol) stored in the second storage area is referred to, the liquid crystal symbol image related to the previous stop is displayed, and when the stop display of the liquid crystal symbol image is started, the first storage area This is because the liquid crystal symbol number (first registered symbol) stored in is referred to and the liquid crystal symbol image related to the current variation display is displayed. As a result, the first liquid crystal symbol reel shown in FIG. 5A and the second liquid crystal symbol reel shown in FIG. It is possible to eliminate inconsistencies that suddenly change to different liquid crystal design images.

  For example, in the previous game, it is assumed that the second liquid crystal symbol reel shown in FIG. 5B is determined and the liquid crystal symbol image that has been stopped is an image corresponding to the liquid crystal symbol number 8. If the first liquid crystal symbol reel shown in FIG. 5A is determined in this game, the liquid crystal symbol number 8 is toggled at the start of the variation of the liquid crystal symbol image to correspond to the liquid crystal symbol number 0. After the liquid crystal design image is replaced, the variable display is started. That is, when a variable display is started when the liquid crystal symbol image imitating “sealing” corresponding to the liquid crystal symbol number 8 is stopped and displayed, “sealing” corresponding to the liquid crystal symbol number 8 is displayed as the liquid crystal symbol number 0. Instead of the liquid crystal symbol image imitating “one” corresponding to, the variable display is started. However, in the present embodiment, when the same liquid crystal symbol number is stored in a different storage area of the liquid crystal RAM 204c and the liquid crystal symbol image starts to be displayed in a variable manner, the liquid crystal symbol number stored in the second storage area (second Since the registered symbols are referred to, the display of variation can be started by taking over the previous liquid crystal symbol reel. For this reason, it is possible to eliminate the inconsistency that the liquid crystal symbol image that has been stopped and displayed is suddenly replaced with a different liquid crystal symbol image at the start of the variation of the liquid crystal symbol image.

  In this embodiment, the second registered symbol is updated to the first registered symbol when the middle symbol stopped liquid crystal command is received in step S2108. However, the left symbol stopped liquid crystal command or the right symbol stopped liquid crystal command is configured. When the command is received, the second registered symbol may be updated to the first registered symbol, and if it is after the high-speed liquid crystal symbol image display that is difficult for the player to see, the update is performed. The timing is not limited.

(Step S2109)
Next, the liquid crystal CPU 204a designates display control table data (lower table data) as in step S2105.

(Step S2110)
If it is determined in step S2106 that the symbol stop liquid crystal command has not been received, the liquid crystal CPU 204a executes processing corresponding to a liquid crystal command other than the registered symbol liquid crystal command, the symbol rotation liquid crystal command, and the symbol stop liquid crystal command. . For example, display control table data corresponding to various liquid crystal commands is designated, and data corresponding to various liquid crystal commands is generated.

  FIG. 13 is a flowchart showing the symbol replacement process in step S2300, and is a process when the symbol replacement process function is called as the call function name from the lower table data shown in FIG. 7A. Although there are various functions other than the symbol replacement function in the calling function name of the lower table data shown in FIG. 7A, in this embodiment, in order to facilitate understanding, Processing is omitted.

(Step S2301)
First, the liquid crystal CPU 204a refers to the lower table data designated in step S2105 or step S2109, and determines whether or not the symbol replacement function has been called. As a result, if it is determined that the symbol replacement processing function has been called, the process proceeds to step S2302, and if it is determined that the symbol replacement processing function has not been called, the symbol replacement processing ends.

(Step S2302)
The liquid crystal CPU 204a refers to the lower table data specified in step S2105 or step S2109, and determines whether or not a stop flag set in advance in the lower table is ON. As a result, if it is determined that the stop flag is ON, the process proceeds to step S2303. If it is determined that the stop flag is OFF, the process proceeds to step S2306. This stop flag is set to ON / OFF in the specified lower table data. When the stop flag is ON, the liquid crystal symbol image is stopped after the high-speed fluctuation display and the low-speed fluctuation display. Display is performed.

(Step S2303)
If it is determined in step S2302 that the stop flag is ON, the liquid crystal CPU 204a stores the liquid crystal symbol number (first registered symbol) of the column that is stored in the first storage area of the liquid crystal RAM 204c and is about to be stopped. Referring to, information on the liquid crystal symbol reel used in the stop display of the liquid crystal symbol image is determined.

  Specifically, whether or not the liquid crystal symbol number (first registered symbol) of the column that is stored in the first storage area of the liquid crystal RAM 204c and is intended to be stopped is the liquid crystal symbol number 8 of the special symbol ( First registration symbol = liquid crystal symbol number 8?), And if the first registration symbol = liquid crystal symbol number 8 is not determined, information on the first liquid crystal symbol reel is determined on the assumption that the first liquid crystal symbol reel is used. If the first registered symbol = liquid crystal symbol number 8, information on the second liquid crystal symbol reel is determined on the assumption that the second liquid crystal symbol reel is used. Then, as the liquid crystal symbol reel information, the maximum number of liquid crystal symbol images associated with each liquid crystal symbol reel is determined as mod. That is, in the present embodiment, mod = 8 is determined unless the first registered symbol = liquid crystal symbol number 8, and mod = 9 is determined if the first registered symbol = liquid crystal symbol number 8.

(Step S2304)
Next, the liquid crystal CPU 204a adds the difference value set in the lower table data designated in step S2105 or step S2109 to the liquid crystal symbol number (first registered symbol) stored in the first storage area of the liquid crystal RAM 204c. Then, a new liquid crystal symbol number is calculated.

(Step S2305)
The liquid crystal CPU 204a corrects the liquid crystal symbol number calculated in step S2304 so as to be within the range of the liquid crystal symbol number of the liquid crystal symbol reel determined in step S2303, and displays the corrected liquid crystal symbol number as the liquid crystal symbol of the display symbol. The number is stored in the display symbol storage area of the liquid crystal RAM 204c. As a result, when the liquid crystal symbol image is stopped from the high-speed variation variation display to the low-speed variation variation display, the liquid crystal symbol image can be replaced in accordance with the first registered symbol.

  Here, correcting the liquid crystal symbol number means dividing the liquid crystal symbol number calculated in step S2304 by the maximum number (mod) of the liquid crystal symbol images determined in step S2303, and calculating a remainder value resulting from the division. The calculation means that the calculated remainder value is corrected and stored in the display symbol storage area of the liquid crystal RAM 204c.

  For example, when the first registered symbol = 7 and the difference value = + 1, the liquid crystal symbol number = 8 is calculated as a new liquid crystal symbol number in step S2304. Here, if mod = 8 is determined in step S2303 to use the first liquid crystal symbol reel, the remainder value is 0, and the liquid crystal symbol number = 0 is determined. Further, if mod = 9 is determined to use the second liquid crystal symbol reel, the remainder value is 8, and the liquid crystal symbol number = 8 is determined. Thus, if the first liquid crystal symbol reel is determined, the symbols can be changed by toggling with the eight liquid crystal symbol numbers, and if the second liquid crystal symbol reel is determined, nine liquid crystal symbol reels can be replaced. Toggle with the number to replace the symbol.

(Step S2306)
Then, the liquid crystal CPU 204a stores in the second storage area of the liquid crystal RAM 204c and determines whether or not the liquid crystal symbol number (second registered symbol) of the column to be updated is the liquid crystal symbol number 8 of the special symbol (second registration). Design = liquid crystal design number 8?). As a result, if it is determined that the second registered symbol is a special symbol, the process proceeds to step S2307. If it is determined that the second registered symbol is not a special symbol, the process proceeds to step S2308.

(Step S2307)
If it is determined in step S2306 that the second registered symbol is a special symbol, the liquid crystal CPU 204a assumes that the second liquid crystal symbol reel has been determined, and toggles with the MAX value +1 of the liquid crystal symbol number of the first liquid crystal symbol reel. The liquid crystal symbol number stored in the display symbol storage area of the liquid crystal RAM 204c is updated.

  Specifically, as described in steps S2303 to S2305 above, a predetermined update value is added to the liquid crystal symbol number stored in the display symbol storage area of the liquid crystal RAM 204c, and the added liquid crystal symbol number is set to the second liquid crystal symbol number. Dividing by mod = 9 corresponding to the liquid crystal symbol reel, the remainder value resulting from the division is stored in the display symbol storage area of the liquid crystal RAM 204c.

(Step S2308)
If it is determined in step S2306 that the second registered symbol is not a special symbol, the liquid crystal CPU 204a assumes that the first liquid crystal symbol reel has been determined, and toggles with the MAX value of the liquid crystal symbol number of the first liquid crystal symbol reel. The liquid crystal symbol number stored in the display symbol storage area of the liquid crystal RAM 204c is updated. This process is the same as that in step S2307 except that mod = 8 corresponding to the first liquid crystal symbol reel is set.

  Here, as shown in step S2108, the second registered symbol referenced in step S2306 is updated to the first registered symbol in the current game upon reception of the middle symbol stop liquid crystal command. . Therefore, the second registered symbol before receiving the middle symbol stop liquid crystal command remains the first registered symbol in the previous game, and the second registered symbol after receiving the middle symbol stopped liquid crystal command is the current registered symbol. This is the first registered symbol in the game.

  Therefore, the previous liquid crystal symbol reel can be taken over and toggled before the start of the stop display of the liquid crystal symbol image in the middle row. On the other hand, after the start of the stop display of the liquid crystal symbol image in the middle row (at the time of the change display when the stop display is performed after the change display of the high speed change through the change display of the low speed change), the second registered symbol has already been updated. Therefore, it can be toggled corresponding to the liquid crystal symbol reel of this time.

(An example of a liquid crystal design image displayed on the liquid crystal display unit 138)
Next, an example of a liquid crystal symbol image displayed on the liquid crystal display unit 138 will be described with reference to FIGS.

  14 and 15 show the concept of a liquid crystal symbol image drawn in the image display region 204f in the virtual display region 204e of the VRAM 204d and the actual liquid crystal symbol image displayed on the liquid crystal display unit 138. FIG.

  Here, (a-1), (b-1),..., (G-1) in FIGS. 14 and 15 show the concept of the liquid crystal design image drawn in the virtual display area 204e. (A-2), (b-2),..., (G-2) of FIG. 15 show actual liquid crystal design images displayed on the liquid crystal display unit 138. In addition, the liquid crystal design image drawn in the virtual display area 204e of FIG. 14A-1 is displayed on the liquid crystal display unit 138 as shown in FIG. 14A-2. 14 (a-1) and FIG. 14 (a-2) correspond to each other. The same applies to (b-1) and (b-2),..., (G-1) and (g-2) in FIGS.

  14A-1 and 14A-2 show a state in which the liquid crystal symbol image from the previous game is stopped and displayed.

  At this time, as shown in FIG. 14 (a-1), the liquid crystal symbol images corresponding to the first symbol and the second symbol in each column are drawn below the image display region 204f in the virtual display region 204e. In the center of the display area 204f, a liquid crystal symbol image corresponding to the fourth symbol of each column is drawn.

  As a result, as shown in FIG. 14A-2, a liquid crystal symbol image corresponding to the fourth symbol of each column is displayed at the center of the liquid crystal display unit 138. Here, the liquid crystal symbol numbers of the fourth symbol in each column are “0, 2, 4” in order from the left, and therefore, the numbers “1, 3, 5” are imitated in the center of the liquid crystal display unit 138. The displayed liquid crystal design image is displayed.

  Then, as the current game, when the player operates the start lever, the liquid crystal CPU 204a receives the registered symbol liquid crystal command and the symbol rotation liquid crystal command from the sub-control board 202, and displays control table data (lower table data). Based on the above, the fluctuation display of the liquid crystal design image is performed. That is, based on the received registered symbol liquid crystal command, the first registered symbol in the current game is determined, the lower table data is specified based on the received symbol rotation liquid crystal command, and based on the specified lower table data, Variation display of the liquid crystal design image is performed.

  As shown in FIG. 14 (b-1), as an example of the present embodiment, the lower table data corresponding to the symbol of each column specified based on the symbol rotation liquid crystal command is the first table of each column at the start of fluctuation. The liquid crystal symbol images corresponding to the 4 symbols and the 5 symbols are set to be drawn on the upper part of the image display region 204f in the virtual display region 204e.

  Further, since the stop flag is turned off in the lower table data of the symbol rotation liquid crystal command, the liquid crystal symbol image is replaced by the registered symbol liquid crystal command (first registered symbol) received in the current game at this time. It is configured so that there is nothing.

  That is, when shifting from the state in which the liquid crystal symbol image is stopped to the state in which the variable display is started, regardless of the registered symbol liquid crystal command (first registered symbol) received in the current game, With reference to the liquid crystal symbol reel corresponding to the received registered symbol liquid crystal command (second registered symbol) and the liquid crystal symbol number set as the current display symbol, the liquid crystal is displayed so that the same liquid crystal symbol image is displayed. The symbol number is determined (see steps S2306 to S2308 in FIG. 13). For example, the liquid crystal symbol number of the second symbol in each column in the current game is determined to be the same number as the liquid crystal symbol number of the fourth symbol in each column in the previous game.

  As a result, as shown in FIG. 14 (b-2), in the liquid crystal display unit 138, even when the liquid crystal symbol image is shifted from the stopped display state to the state in which the variable display is started, the same. A liquid crystal design image is displayed. In particular, the liquid crystal symbol number is determined so that the same liquid crystal symbol image is displayed by taking over the liquid crystal symbol reel corresponding to the registered symbol liquid crystal command (second registered symbol) received in the previous game. It is possible to eliminate the inconsistency that the liquid crystal symbol image that has been stopped and displayed is suddenly replaced with a different liquid crystal symbol image at the start of the change.

  Thereafter, as shown in FIGS. 14C-1 and 14D-1, every time there is a predetermined wait timer (predetermined frame), the liquid crystal symbol image corresponding to each symbol in each column is displayed in the virtual display area. Drawing is performed so as to move to the lower part of the image display area 204f in 204e.

  As a result, as shown in FIGS. 14 (c-2) and (d-2), on the liquid crystal display unit 138, the liquid crystal symbol image is variably displayed so as to scroll from top to bottom.

  After FIG. 14 (d-1), the liquid crystal symbol image is replaced (the liquid crystal symbol number is updated), and the process returns to FIG. 14 (b-1) until the stop switch 130 is operated by the player. 14 (b-1) to (d-1) are repeated, and the liquid crystal symbol image is displayed in a variable manner (see steps S2306 to S2308 in FIG. 13).

  When the stop switch 130 is operated by the player, the liquid crystal CPU 204a receives the symbol stop liquid crystal command from the sub control board 202, and stops displaying the liquid crystal symbol image based on the display control table data (lower table data). I do. That is, the lower table data is designated based on the received symbol rotation liquid crystal command, and the liquid crystal design image is stopped and displayed based on the designated lower table data.

  FIG. 16 is an example of the structure of the lower table of each symbol in the middle column specified when the middle symbol stop liquid crystal command is received.

  The middle row lower table shown in FIG. 16 has a total of five lower tables of the first to fifth symbols in the middle row. The lower table 40 shown in FIG. 16A shows the lower table of the fifth symbol in the middle column, the lower table 41 shown in FIG. 16B shows the lower table of the fourth symbol in the middle column, and FIG. The lower table 42 shown in FIG. 16 shows the lower table of the third symbol in the middle column, the lower table 43 shown in FIG. 16D shows the lower table of the second symbol in the middle column, and the lower table shown in FIG. The table 44 shows the lower table of the first symbol in the middle row.

  In addition, the lower table in the middle column shown in FIG. 16 includes, as an example, the name of the texture to be drawn (liquid crystal design image), the horizontal and vertical sizes of the liquid crystal design image to be drawn, the X coordinate and Y of the liquid crystal design image to be drawn. It is composed of coordinates, a difference value from the first registered symbol, a stop flag, a call function name, a wait timer value indicating a drawing standby time, and a movement value of an image to be drawn.

  Here, regarding the lower table of each symbol in the middle row shown in FIG. 16, the X coordinate is the same as that of each symbol in the middle row (X coordinate = 256), whereas the Y coordinate is the middle row. The coordinates are different for each symbol. Regarding the movement value, the X movement value is set to 0 for each symbol in the middle row, whereas the Y movement value is set to a negative value (−32). As a result, the liquid crystal symbol image corresponding to each symbol in the middle row does not move to the left and right (X coordinate) as shown in FIGS. The image is drawn in the virtual display area 204e.

  Also, regarding the lower table of each symbol in the middle column shown in FIG. 16, the call function name “z-sasaikae” is a call function name for calling the symbol replacement function shown in FIG. Each symbol in the middle row is ON (stop flag = 01).

  15 (e-1) and 15 (e-2), after the left symbol stop liquid crystal command and the right symbol stop liquid crystal command have been received and the liquid crystal symbol images in the left and right columns are stopped and displayed, a new middle symbol stop liquid crystal is newly displayed. This shows a state when a command is received and an attempt is made to start the stop display of the liquid crystal symbol image in the middle row. Then, based on the lower table of each symbol in the middle row shown in FIG. 16 corresponding to the middle symbol stop liquid crystal command, the middle row liquid crystal symbol image is stopped and displayed.

  As shown in FIG. 15 (e-1), drawing of the symbols in the left and right columns is completed, and the liquid crystal symbol images corresponding to the first symbol and the second symbol are drawn in the lower part of the image display area 204f. Further, each symbol in the middle row receives a new symbol stop liquid crystal command, so that the display symbol of each symbol is replaced based on the first registered symbol corresponding to the current registered symbol liquid crystal command (FIG. 13 above). Steps S2301 to S2305).

  Specifically, if the liquid crystal symbol number “6, 8, 6” is designated in the order of left, middle, and right column as the liquid crystal symbol number of the first registered symbol by the registered symbol liquid crystal command, each symbol in the middle column Is added after adding the “difference value” in the lower table of the middle row shown in FIG. 16 with the liquid crystal symbol number “8” of the first registered symbol in the middle row as a reference and replacing the added design symbol number. .

  For example, according to the middle table fifth symbol lower table 40 shown in FIG. 16A, the middle row fifth symbol is the difference value “+1” to the liquid crystal symbol number “8” of the first registered symbol in the middle row. ”And the added liquid crystal symbol number“ 9 ”is replaced with the corrected (toggled) liquid crystal symbol number“ 0 ”. In addition, according to the fourth symbol lower table 41 in the middle row shown in FIG. 16B, the fourth symbol in the middle row is the difference value “0” to the liquid crystal symbol number “8” of the first registered symbol in the middle row. ”And the added liquid crystal symbol number“ 8 ”is replaced. According to the lower table 42 of the third symbol in the middle column shown in FIG. 16C, the third symbol in the middle column is the second symbol in the middle column. The difference value “−1” is added to the liquid crystal symbol number “8” of one registered symbol, and the added liquid crystal symbol number “7” is replaced. The same applies to the middle symbol second symbol lower table 43 shown in FIG. 16D and the middle symbol first symbol lower table 44 shown in FIG.

  Hereinafter, as shown in FIGS. 15 (e-1), (f-1), and (g-1), the “wait timer value” and “movement value” of the lower table in the middle column shown in FIG. 16 are referred to. Thus, the liquid crystal design image is drawn in the virtual display area 204e of the VRAM 204d from the top to the bottom (see step S2200 in FIG. 11).

  At this time, the “wait timer value” and the “movement value” in the lower table in the middle row shown in FIG. 16 are slower than the high-speed fluctuation display as shown in FIGS. 14 (b-1) to (d-1). It is set so as to be a variable display. That is, the “wait timer value” in the lower table in the middle row shown in FIG. 16 is set to a longer time than the “wait timer value” in the lower table corresponding to FIGS. 14 (b-1) to (d-1). Has been.

  As a result, as shown in FIGS. 15 (e-2), (f-2), and (g-2), on the liquid crystal display unit 138, the liquid crystal symbol image is scroll-displayed at a low speed from top to bottom. Then, as shown in FIG. 15 (g-2), stop display is performed.

  In the present embodiment, as shown in FIG. 15 (g-1), at the time of stop display, the liquid crystal symbol image corresponding to the fourth symbol in each column is finally drawn in the center of the image display area 204f. Will be. As a result, a liquid crystal symbol image corresponding to the fourth symbol is displayed at the center of the liquid crystal display unit 138 as shown in FIG. Accordingly, in the lower table 41 of the fourth symbol in the middle row shown in FIG. 16B, “difference value = 0”, and the fourth symbol is the first registered symbol in the middle row corresponding to the current registered symbol liquid crystal command. Is supposed to show.
