Description

  The present invention relates to a gaming machine having a plurality of different display times for different display of symbols.

  Conventionally, in gaming machines that display symbols on a display device, for example, pachinko machines, the number of occurrences of events can be stored as the number of reserves, and the number of holds can be reduced by sequentially changing the number of occurrences. Has been done. In such gaming machines, the number of revolutions per hour, that is, the so-called “start” is ascertained by the gaming store for each gaming machine, and used for calculating profits and the like for each gaming machine.

  However, in a conventional gaming machine, the symbol variable display time is determined by the internal lottery of the gaming machine itself, and the game store cannot adjust the length of the variable display time. Therefore, the amusement store side does not adjust the variable display time when the variable display time is selected continuously or when the variable display time is selected continuously. It has been extremely difficult to maintain the number of display times per hour desired by the game machine developer.

In recent years, a gaming machine has been proposed in which the length of the symbol variable display time is changed according to the number of the reserved numbers. However, in a gaming machine that changes the length of the symbol variable display time depending on the number of holds, even if the symbol variable display time for each number of holds is adjusted, the number of times of variable display per hour cannot be adjusted. There was a case. For example, when a state with a small number of holds lasts for a long time or a state with a large number of holds lasts for a long time, the variation display time is biased, and it is difficult to adjust the number of times of change display per hour as a whole. Met.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a gaming machine capable of reducing fluctuations related to the number of times of display change of symbols per hour.

The invention of claim 1 is a display device that can display and stop displaying symbols, and a storage means that stores a plurality of variable display times that are preset for the symbol variation display in the display device. Selecting means for selecting a variable display time from a plurality of variable display times of the storage means due to the occurrence of a trigger, a symbol fluctuation control means for changing a symbol on the display device for the selected variable display time, An occurrence trigger counting unit that counts the number of occurrences of the trigger and subtracts the number of times the symbol has been changed from the count of occurrences of the trigger to calculate the remaining number of occurrence triggers. In a gaming machine in which the fluctuation control means changes the symbol by the number of occurrence trigger remaining times, a reference fluctuation display time is preset as the symbol fluctuation display time, and the plurality of variables are changed. The display time includes a short fluctuation display time whose fluctuation display time is shorter than the reference fluctuation display time, and a long fluctuation display time whose fluctuation display time is longer than the reference fluctuation display time. A variation display continuous determination means for determining whether the symbol is interrupted , and the variation display time of the symbol when the variation display of the symbol is determined to be continuous by the variation display continuous determination means, and the counted count The reference variation display time is subtracted from the time by the subtracting means for each symbol variation display, and the variation display time of the symbol is counted until it is determined that the variation display of the symbol is interrupted by the variation display continuous judging means. a variable display continuous time count means repeating the updating the count time is added to the counting time which is subtracted by the subtraction means for each display variations of the symbol and the previous A variable display continuous time comparison means for comparing the counting time which is updated with the reference variable display time, when selecting the variable display time by the selecting means, the result of comparison by the variable display continuous time comparison means, said reference When the updated counting time is longer than the variable display time, the probability of selecting the short variable display time from the plurality of variable display times is set higher than the probability of selecting the long variable display time. When the updated counting time is shorter than the reference variation display time, the probability of selecting the long variation display time from the plurality of variation display times is compared with the probability of selecting the short variation display time. A variable display time selection rate switching means for setting a high value, and when the variable display continuous determination means determines that the variable display of the symbol is interrupted, the counting time Is returned to the initial value .

  According to a second aspect of the present invention, in the first aspect of the present invention, the variation display continuation determining means determines whether the occurrence trigger remaining number value is '1' or more, or at least one state in which the symbol is currently variably displayed. It is determined that the display is continuous, and it is determined that the change display of the symbol is interrupted when the occurrence opportunity remaining number value is “0” and the symbol is not currently displayed in a variable manner. .

  According to the first aspect of the present invention, when the variable display time is selected by the selection means, as a result of the comparison by the variable display continuous time comparison means, the continuous display time of the variable display is longer than the reference fluctuation display time. The probability of selecting a short variation display time with a variation display time shorter than the reference variation display time from a plurality of variation display times compared to the probability of selecting a long variation display time with a variation display time longer than the reference variation display time When the setting is high and the continuous display time of the fluctuation display is shorter than the reference fluctuation display time, the probability of selecting the long fluctuation display time from multiple fluctuation display times is compared to the probability of selecting the short fluctuation display time. The variable display time selection rate switching means is set to a high value, so that the change display time of the entire continuous display can be corrected, and the average change table is displayed at the preset reference change display time. It is possible to approximate the time. As a result, it is possible to keep the number of times of variable display per time constant.

According to the first aspect of the present invention, when the variation display continuous determination means determines that the variation display of the symbol is interrupted, the variation display is performed by returning the counting time of the time during which the variation display is continued to the initial value. It is possible to prevent counting of extra time that is not performed.

  According to the second aspect of the present invention, the variation display continuous determination means determines that at least one state where the occurrence trigger remaining number value is '1' or more or the symbol is currently in the variable display, the symbol variation display is continuous. It is possible to accurately grasp the discontinuity of the fluctuation display by judging that the fluctuation display of the symbol is interrupted in the state where the occurrence opportunity remaining number value is “0” and the symbol is not currently displayed. It becomes.

Hereinafter, each required part will be further described in detail.

  The display device 9 is capable of displaying at least a design, and is composed of a liquid crystal, a dot matrix, an LED display device, or the like. A symbol display unit 45 is incorporated, and most of the other is a special symbol display unit 42. The special symbol display unit 42 corresponds to a display device that can display and stop displaying symbols in the present invention.

  The special symbol display unit 42 performs a variation display of a symbol for one variation display time selected from a plurality of variation display times set in advance, and then determines a determination result by a determination unit that determines whether or not a game is missed. The player is notified in a stop mode after the symbol variation is displayed. The special symbol display unit 42 of this embodiment includes a left display region, a central display region, and a right display region that are divided into three display regions arranged side by side. The left special symbol is displayed in the central display region in the left display region. The middle special symbol and the right special symbol in the right display area can be displayed in a variable manner and stopped as a special symbol (determination symbol) for notifying the success / failure determination result for the jackpot. The special symbol corresponds to the symbol of the present invention. The special symbol display unit 42 may display a background image (including characters, background, characters, etc.) in addition to the special symbol. Variation display may be possible due to conditions. In this embodiment, the special symbols that are changed and stopped in the left display area, the central display area, and the right display area are “0, 1, 2, 3, 4, 5, 6, 7, 8, 9”. , 10, 11 ”. In the present embodiment, the special symbols stopped in the left display area, the central display area, and the right display area are formed in a stop pattern (a state in which the same numbers are arranged like '7, 7, 7'). When the jackpot symbol is stopped and displayed, it is a jackpot and the game shifts to a special game (bonus game) that gives a privilege to the player. In the case of the special game, the open / close plate 16 of the grand prize opening 15 is opened so that the game ball falling on the surface of the gaming area 6 can be easily received, and the big prize opening 15 can be won (entered). When there is a prize at the prize opening 15, a predetermined number of game balls are paid out as prize balls.

  The variation display time of the special symbol is a variation mode together with a method of variation of the special symbol (for example, variation direction, variation speed, scaling / rotation of the symbol, presence / absence of reach, presence / absence of symbol different from the special symbol, etc.) Is set. In this embodiment, variation modes 1 to 17 having different variation display times and variation methods are set in advance and stored in the storage unit. Table 1 shows the variation display time and variation method (variation content, presence / absence of reach) of the variation modes 1 to 17.

  In Table 1, “the pattern fluctuates from top to bottom” indicates that the left, middle, and right special symbols fluctuate from top to bottom as shown by 17-A in FIG. Indicates that the special symbol fluctuates from top to bottom while emitting light, as shown by 17-B in FIG. 17, and “varies while wavy” indicates that the special symbol is changed as indicated by 17-C in FIG. It shows that it fluctuates from top to bottom while wavy from side to side. Further, the plurality of fluctuation display times include a short fluctuation display time shorter than the reference fluctuation display time and a long fluctuation display time longer than the reference fluctuation display time. In this embodiment, the reference fluctuation display time is set to 5 seconds.

  In this embodiment, the variation mode is divided into a short variation display time high selection rate selection table, a long variation display time high selection rate selection table, and a big hit time selection table and stored in the storage means. One selection table is selected when the variation mode is selected, and one variation mode is selected from the selected selection table. The short variation display time high selection rate selection table and the long variation display time high selection rate selection table are selected when the determination result by the determination means is out of place. For the short variation display time high selection rate selection table, the probability that the variation mode having the short variation display time is selected is set higher than the probability that the variation mode having the long variation display time is selected. On the other hand, for the long variation display time high selection rate selection table, the probability that the variation mode having the long variation display time is selected is higher than the probability that the variation mode having the short variation display time is selected. It is set high. On the other hand, the selection table for jackpot time is selected when the determination result for the jackpot is a win.

  In Table 1, the variation modes 1 to 6 of the short variation display time high selection rate table and the variation modes 7 to 12 of the long variation display time high selection rate table that are selected when the jackpot determination result is out of place. The selection is determined by the combination of the presence / absence of reach and the obtained random number value of the variation mode selection counter (numerical value range 0 to 35). For example, with respect to the variation mode 1, the obtained random number value of the variation mode selection counter is the value shown in the range column of the selection random number (0 to 35) in Table 1, The selection probability at that time is 96.0%, which is the result of the product of 48/50 preset as the ratio without reach and the selection ratio 36/36 in the variation mode selection counter, The variation mode 2 is selected when there is a reach and the obtained random number value of the variation mode selection counter is 0 to 15, and the selection probability at that time is preset as a ratio with reach. The result of the product of 2/50 and the selection ratio 16/36 in the variation mode selection counter is about 1.8%. The reach presence / absence selection and variation mode selection counter will be described in detail later.

  On the other hand, when the jackpot success / failure determination result is a win, since there is always reach, the variation modes 13 to 17 of the jackpot hour selection table selected when the jackpot hit / fail determination result is a win The selection is determined by the obtained random number value of the variation mode selection counter. For example, the variation mode 13 is selected when the obtained random number value of the variation mode selection counter is 0 to 15, and the selection probability at that time is about 44 obtained from the selection ratio 16/36 in the variation mode selection counter. The variation mode 14 is selected when the obtained random number value of the variation mode selection counter is 16 to 25, and the selection probability at that time is selected from the selection ratio 10/36 in the variation mode selection counter. About 27.8% obtained.

  The reach is in a variable display mode in which a special symbol mode, that is, a jackpot symbol combination is easily displayed in a stage before the fixed symbol is displayed in a fixed stop state after the special symbol is displayed on the special symbol display unit 42. A state reminiscent of a player. As one of the reach, only the display area for displaying the final stop symbol is left among the display areas of the special symbol display unit 42, and the special symbols are combined in a specific combination (for example, the same symbol in the remaining two display areas). ) Can be given as a stop display. In this example, after the special symbol display unit 42 starts variably displaying in the special symbol display unit 42, in a stage before the fixed stop display is performed, only the central display region is left, and the symbols are displayed in a specific combination in the remaining two display regions ( For example, the case where the display is stopped so as to be the same symbol) is set as reach.

  The normal symbol display unit 45 variably displays and stops a normal symbol for determining a small hit such as a symbol or a picture (character). The normal symbols that are changed and stopped on the normal symbol display unit 45 in the present embodiment are ten patterns of “0, 1, 2, 3, 4, 5, 6, 7, 8, 9”. .

  The start winning opening 10 is provided directly below the special symbol display section 42, and the two movable pieces 10a and 10b are in a narrow open state (normal state) in which it is difficult to win (enter) a ball substantially vertically by a starting start opening opening solenoid. And a substantially V-shaped (reverse C-shaped) shape that is easy to win (enter a ball) and is controlled so as to be changeable. The opening and opening of the start winning opening 10 is performed when a normal symbol is changed on the normal symbol display unit 45 and then a fixed stop is displayed at a specific normal symbol and a small hit (per normal symbol) is established.

  Further, on the back of the game board 3, a start winning port detection switch (start winning port sensor) for detecting a game ball won (entered) in the start winning port 10 is provided in the winning ball passage, In the present embodiment, detection of a winning ball by the start winning opening detection switch is set to the occurrence of an opportunity, and the change display of the special symbol is set to start due to the occurrence of the opportunity. It is set so that the success or failure of the jackpot is determined. Further, even when a special symbol is displayed on the special symbol display unit 42, even if a winning ball is detected by winning at the start winning opening 10, that is, even if an opportunity occurs, a new special symbol is displayed. Since the start winning port detection switch counts the detection of the winning ball by the generation timing counting means, the number of special symbol fluctuation hold (every time the present winning ball detection by the starting winning port detection switch) 1 is added to the number of special symbol fluctuation hold (the number of times of occurrence of the trigger) and the number of special symbol fluctuation hold (the occurrence trigger of the present invention) (Remaining number of times value) is calculated (corresponding to the occurrence trigger remaining number value calculation of the present invention), and the special symbol fluctuation suspension number (occurrence number remaining number value after the addition or subtraction) is stored and the special number is stored. While it holds temporarily variable display start handle, displaying the number of the special symbol variation hold a special symbol variation number of holding storage indicator 51 provided on the lower right of the special symbol display unit 42. In the present embodiment, the maximum value of the special symbol fluctuation suspension number is set to four.

  The normal symbol variation start left gate 19 and the normal symbol variation start right gate 21 detect a game ball passing through both gates 19, 21 by a normal symbol variation start switch provided on the back of the game board 3. Due to this, the normal symbol display unit 45 starts to change the normal symbol. In addition, during the normal symbol variation display, the number of normal symbol variation suspensions generated by the game ball passing through the normal symbol variation start left gate 19 and the normal symbol variation start right gate 21 is a maximum of four times. It is stored as the number of normal symbol fluctuation hold, and the number of normal symbol fluctuation hold is reduced by starting the fluctuation of the normal symbol. Furthermore, a left sleeve winning port detection switch and a right sleeve winning port detection switch for detecting the winning balls of the left sleeve winning port 23 and the right sleeve winning port 25, and the left dropping winning port 27 and the right dropping winning port 29 are detected. A left drop winning opening detection switch and a right drop winning opening detection switch for detecting a winning ball are respectively provided on the back of the corresponding game board.

  The big prize opening 15 is provided below the start prize opening 10 and includes an opening / closing plate 16 that is opened and closed by a big prize opening opening solenoid provided on the back surface of the game board 3. The special winning opening 15 is normally in a state in which the opening / closing plate 16 is closed, and a part of the special winning opening 15 has a specific area that is opened when the special winning opening 15 is opened to allow a winning. A winning opening 52 is provided. Further, the specific area winning opening 52 is provided with an open / close door that is opened and closed by a specific area opening solenoid in a predetermined condition. The specific area winning opening 52 is provided with a specific winning ball detection switch (specific area sensor) for detecting a specific winning ball so that the right to continue opening the large winning opening 15 is established by detecting the winning ball. Has been. In addition, a winning ball count switch (count sensor) for detecting a winning ball that has won the big winning port 15 and has not won the specific area winning port 52 is provided in the approximate center of the big winning port 15. It has been.

  The launching device 53 has a launching motor that is driven by the operation of the operation lever 54 on the back side, and the game ball is ejected by the driving of the launching motor. The launch ball fired by the launch device 53 is guided to the game area 6 through a launch ball guide path formed between the outer guide rail 4 and the inner guide rail 5 erected on the game board surface. The game ball guided to the game area 6 rolls downward and rolls down and wins the respective devices and the winning holes, or if no winning is made anywhere, from the out port 17 of the game board 3. It is discharged to the back side.

  A game performed by the gaming machine 1 will be briefly described. In the gaming machine 1, when game balls launched toward the game area 6 by the launching device 53 win a variety of winning holes in the game area 6, a predetermined number of game balls are awarded as prize balls, which will be described later. It is paid out to the upper ball receiving tray 36 from the apparatus. Further, when a game ball passes through the normal symbol change start left gate 19 and the normal symbol change start right gate 21, and the game ball is detected by the normal symbol change start switch, the main control circuit 120A described later is sent to. When a detection signal is sent and the number of normal symbol fluctuation hold is less than 4, a random number for determining a small hit / stop normal symbol is acquired, and the acquired random number value is stored in a normal symbol numerical value in the RAM of the main control circuit 120A. Once stored in the area. Then, the stored small hit determination / stop normal symbol determination random number value is sequentially read out, and whether or not the small hit (ordinary symbol) is determined based on the read random number value, the normal symbol display unit At 45, normal symbol variation starts and stops after a predetermined time variation. At this time, if the small hit determination result is a small hit, the small hit normal symbol, in this example, stops at an odd number, the start winning opening 10 is opened and opened, and the game ball wins (wins) It becomes easy to do. When a game ball wins (enters) the start winning port 10, a predetermined number (5 in this example) of game balls are paid out from the prize ball payout device as prize balls.

  When a game ball is won at the start winning opening 10 and a winning ball is detected by the start winning opening detecting switch, a detection signal is sent to the main control circuit 120A, and the number of special symbol fluctuation hold is less than 4. For example, various random number values such as a jackpot winning / not determining random number value and a jackpot symbol determining random number value are acquired, and the acquired numerical values are temporarily stored in a corresponding storage area of the RAM of the main control circuit 120A. Then, the stored jackpot winner determination random number value is sequentially read out, the jackpot winner determination is performed based on the read jackpot winner determination random number value, and a special symbol display unit based on the winner determination result The symbol to be stopped and displayed is determined. In addition, before the start of the variation of the special symbol, one variation mode (variation display time and variation method) is selected and determined from a plurality of variation modes (variation display time and variation method), and according to the determined variation mode, The special symbol starts to change in the special symbol display unit 42. In the present embodiment, 1 is subtracted from the number of special symbol variation suspensions after the variation mode selection decision.

The selection of the variation mode is performed by counting the time that the variation display of the special symbol is continued and using the counted value ( counting time) . That is, in the gaming machine 1, it is determined by the variable display continuous determination means whether the special symbol variable display is continuous or interrupted, and if the variable display is continuous according to the determination result, the variable display is continuous. The continuous display time, that is, the variable display continuous time is counted by the variable display continuous time counting means. In the present embodiment, whether or not the variation display is continuous or interrupted is determined when the number of special symbol variation suspension is “1” or more, or at least one of the special symbols is currently variably displayed in the special symbol display unit 42. In the other case, that is, when the special symbol variation holding number is “0” and the special symbol display unit 42 is not currently displaying the special symbol in a variable manner. It is determined that the variable display is interrupted, and the count value (counting time) during the variable display that has been counted up to that time is returned to the initial value. Thereafter, the variation display continuous time starts counting from the initial value. In addition, the counting time of the variation display continuous time is updated by subtracting the reference variation display time by the subtracting means for each variation display.

  When the determination of success / failure for the jackpot is missed, the counting time (initial value or updated value if updated) of the variation display continuous time is calculated as the reference variation display time by the variation display continuous time comparison means. If the comparison result shows that the counting time is longer than the reference variation display time, the variation display time selection rate switching means selects the short variation display time that is shorter than the reference variation display time. The probability of performing is set higher than the probability of selecting the long variation display time having a variation display time longer than the reference variation display time. Specifically, a short variation display time high selection rate table is selected from the three types of selection tables shown in Table 1, and one variation mode is selected from the short variation display time high selection rate table. As a result, there is a high possibility that a variation mode having a short variation display time shorter than the reference variation display time will be selected, and the average variation per variation display for the entire continuous variation display time. The display time can be corrected so as to approach the value of the reference variation display time.

  On the other hand, as a result of the comparison, if the counting time is shorter than the reference variation display time, a long variation display time longer than the reference variation display time is set by the variation display time selection rate switching means. The probability of selection is set higher than the probability of selecting a short variation display time with a variation display time shorter than the reference variation display time. Specifically, a long variation display time / high selectivity selection table is selected from the three types of selection tables shown in Table 1, and one variation mode is selected from the selected long variation display time / high selection ratio table. . This increases the possibility that a variation mode having a long variation display time that is longer than the reference variation display time is selected, and the average variation per variation display for the entire continuous variation display time. The display time can be corrected so as to approach the value of the reference variation display time.

  After the special symbol is variably displayed in the special symbol display section 42 for the variation display time of the selected variation mode, it is stopped and displayed as an outlier symbol (a combination that does not result in a state where the same numbers are arranged), It is notified by the stop mode that the determination result is unacceptable. In the case of detachment, the special winning opening 15 is not opened but remains closed.

  On the other hand, if the determination result of the jackpot winning is a winning, the variable display time selection rate switching means is disabled, the jackpot hour selection table is selected from the three types of selection table of Table 1, and the selected One variation mode is selected and determined from the jackpot selection table. Then, after the special symbol is variably displayed on the special symbol display unit 42 for the variation display time of the selected variation mode, the jackpot symbol, which is the same as in the example ('7, 7, 7') In the state where the numbers are arranged), the display is stopped, and a special jackpot is notified by a special symbol stop mode. After the jackpot notification, a special game (bonus game) that gives a privilege to the player is started. In the special gaming state, the open / close plate 16 of the grand prize opening 15 is opened to make it easy to receive the game balls falling on the surface of the gaming area 6 so that the big prize opening 15 can be won (entered). When there is a winning (winning) in the winning opening 15, a predetermined number of game balls are paid out as prize balls by the winning ball payout device. The opening / closing plate 16 has a predetermined number (for example, 10) of winning balls detected after elapse of a predetermined time (for example, 29.5 seconds) or by the specific winning ball detection switch and the winning ball count switch. It is supposed to close at the moment.

If the specific winning ball detection switch detects a winning ball to the specific area winning port 52 while the big winning port 15 is open or within about 2 seconds after the big winning port 15 is closed, the right to repeat the jackpot again And the opening / closing plate 16 is repeatedly opened up to a predetermined maximum number of rounds (number of times), for example, up to 16 rounds (times). During the execution of the special game, the special symbol display unit 42 does not display the variation of the special symbol. At the end of the special game, the count value ( counting time) by the variable display continuous time counting means is returned to the initial value.

  As a plurality of random number counters (random numbers) provided in the main control circuit 120A, there are those shown in Table 2 in this embodiment. The random number counter is not limited to that in Table 2, and an appropriate random number counter may be provided. The contents of the random number counter in Table 2 are as follows.

  The label-TRND-A is used as a jackpot determination unit (determination unit in the present invention) that determines a jackpot that is a transition to a special game (bonus game) that gives a privilege to the player. The numerical value Q1 of the label-TRND-A starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every predetermined time (in this example, 2.0 msec), and when the numerical value reaches “629”. Then, it is rewritten to “0” and the addition is repeated. The numerical value Q1 of the label-TRND-A indicates the occurrence of an opportunity in the present invention when a game ball enters the start winning opening 10 and is detected by the start winning opening detection switch (when an opportunity occurs). It is determined whether or not the jackpot value is acquired as a cause and compared with a jackpot value determined in advance, which is “5” or “500” in this embodiment.

  The label-TRND-R1 is for determining whether or not to reach the reach when the jackpot determination result by the label-TRND-A is out of reach. The label-TRND-R1 starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every predetermined time (2.0 msec). The above addition is repeated. The numerical value Q2 of the label-TRND-R1 is acquired when a ball entering the starting winning port 10 is detected by the starting winning port detection switch, and when the jackpot determination result is out, the numerical value Q2 is determined in advance. Whether or not a reach is determined is compared with the reach establishment value. In this embodiment, when the jackpot determination result by the label-TRND-A is a jackpot, the reach state is always established.

  The label-TRND-T1 is used to select a variation mode that determines a variation display time, a variation method, and the like of the special symbol in the special symbol display unit 42. The value Q3 of the label-TRND-T1 starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 every predetermined time (2.0 msec). It is rewritten to “0” and the addition is repeated again. The numerical value of the label-TRND-T1 is acquired when a ball entering the start winning opening 10 is detected by the start winning opening detecting switch.

  The label-TRND-AZ1 determines a jackpot symbol that is determined and stopped on the special symbol display unit 42 when the jackpot is established. The numerical value Q4 of the label -TRND-AZ1 starts from “0” when the power is turned on and is incremented by “1” every predetermined time (2.0 msec). The above addition is repeated. The numerical value of the label -TRND-AZ1 is acquired when a ball entering the start winning opening 10 is detected by the start winning opening detecting switch. A jackpot symbol corresponding to each numerical value is assigned in advance to the numerical value of the label-TRND-AZ1. In the embodiment, when the numerical value of the label-TRND-AZ1 is “0”, it is “0, 0, 0” which is “0, 0, 0”, and when it is “1”, “1, 1, 1”. 1 slot, 2 for 2 and 2 for 2; 3 for 3, 3 for 3, 3 Like the eyes, each of the numbers is a big hit symbol.

  Labels-TRND-B1 to B3 are used to determine a symbol to be confirmed (disappearing display mode) to be confirmed and stopped on the special symbol display unit 42 when the jackpot determination result by the label-TRND-A is out. Is. The numerical value Q5 of the label-TRND-B1 corresponds to the left special symbol, the numerical value Q6 of the label-TRND-B2 corresponds to the right special symbol, and the numerical value Q7 of the label-TRND-B3 corresponds to the middle special symbol (final stop special symbol).

  The numerical value of the label-TRND-B1 starts from “0” when the power is turned on and is incremented by “1” every predetermined time (2.0 msec). When reaching “11”, it is rewritten to “0”. The addition is repeated again. The value of the label-TRND-B2 starts from “0” when the power is turned on, and is incremented by “1” when the value of the label-TRND-B1 is rewritten to “0”. Then, it is rewritten to “0” and the addition is repeated again. Further, the label-TRND-B3 starts from “0” when the power is turned on, and is incremented by “1” when the numerical value of the label-TRND-B2 is rewritten to “0”, and reaches “11”. Then, it is rewritten to “0” and the addition is repeated again. Thereby, even if the numerical ranges of the labels -TRND-B1 to B3 are the same, it is possible to avoid that the numerical values of the labels -TRND-B1 to B3 are synchronized (added in the same combination).

  The labels -TRND-B1 to B3 are 0 when each numerical value of the labels -TRND-B1 to B3 is "0", 1 is "1", and 2 is "2". Are set as a fixed stop display symbol composed of a left special symbol, a middle special symbol, and a right special symbol displayed on the special symbol display unit 42 when the game is off. The left special symbol displayed on the special symbol display unit 42 at the time of detachment by a combination of numerical values acquired from the labels -TRND-B1 to B3 every time a winning ball is detected by the start winning port detection switch, A fixed stop display symbol consisting of a special symbol and a right special symbol is determined.

  The obtained random number values of Q1 to Q7 are each stored in the corresponding area in the RAM of the main control circuit 120A, and are used sequentially.

  The label -TRND-H is for determining a normal symbol (small hit determination symbol) to be stopped and displayed on the normal symbol display unit 45 and determining a small hit (normal symbol hit). When the gaming machine 1 is turned on, , “1” is added every predetermined time (2.0 msec) starting from “0”, and when “9” is reached, it is rewritten to “0” and the addition is repeated again. The numerical value Q8 of this label-TRND-H is obtained every time the game ball that has passed through the normal symbol variation start left gate 19 or the normal symbol variation start right gate 21 is detected by the normal symbol variation start switch, Up to four are stored in the normal symbol value storage area of the RAM of the main control circuit 120A.

  In addition, a normal symbol (small hit determination symbol) corresponding to each numerical value is assigned in advance to the numerical value Q8 of the label-TRND-H. In the embodiment, when the obtained random number value of the label -TRND-H is “1”, the normal symbol (small hit determination symbol) to be stopped and displayed on the normal symbol display unit 45 becomes “1”, etc. The acquired random number value of H is assigned as a normal symbol (small hit determination symbol) to be stopped and displayed on the normal symbol display unit 45 as it is.

  In this embodiment, the probability of winning a normal symbol is ½. Specifically, when the acquired random number Q8 of the label-TRND-H is an odd number, a small hit is formed, The symbol is also stopped at the winning symbol, and in the normal game state, the start winning opening 10 is opened and opened once for 0.5 seconds. In addition, the acquired random number Q8 of the label-TRND-H is not a small hit in other cases, the normal symbol is also stopped and the start winning port 10 remains in the narrow open state where it is difficult to win. Is done.

  As main flags provided in the main control circuit 120A, in this embodiment, a big hit flag A1, a big hit medium flag A2, a reach flag R1, a changing flag C1, a changing stop flag D1, and the like can be mentioned. These flags are all set to 0 at the initial setting.

  Next, control processing in the gaming machine 1 will be described. First, processing executed by the main control circuit 120A will be described. The CPU of the main control circuit 120A performs the main processing M every predetermined interrupt time (in this example, 2.0 msec) in accordance with each program stored in the ROM of the main control circuit 120A. FIG. 4 is a flowchart of the main process M.

  In the main process M, it is first determined whether or not the current power is turned on (S11). If the power is turned on this time, an initial setting process (S12) is performed.

  In the initial setting process (S12), stack setting, interrupt time setting (2.0 msec in this example), CPU setting, SIO, PIO, CTC setting and the like are performed. The initial setting process (S12) is a process that is necessary only when the power is turned on, and is executed only in the first round, and thereafter, the process proceeds to the next command output process (S13) without being executed.

  In the command output process (S13), when there is an output command in the command buffer (not shown) of the computer in the main control circuit 120A, the output command is output to the corresponding control circuit (display control circuit 130A, etc.). . Examples of commands include a change mode determination command, a symbol stop command, and a stop symbol command.

  In the sensor input process (S14), an input process is performed when various sensors detect signals. The sensor received a normal symbol variation start switch (normal symbol gate sensor) for detecting the passing of the game ball of the normal symbol variation start left gate 19 and the normal symbol variation start right gate 21, and the start winning opening 10 was won. Starting winning port detection switch (start winning port sensor) for detecting a ball, winning ball count switch (count sensor) for detecting a winning ball at the large winning port 15, a specific winning ball detection switch (specific area sensor), and the like. be able to.

  In the random number update process (S15), each numerical value Q1 of the label-TRND-A, label-TRND-R1, label-TRND-T1, label-TRND-AZ1, label-TRND-B1 to B3, label-TRND-H Update is repeated for ~ Q8. FIG. 5 is a flowchart of the random number update process (S15). In this random number update process (S15), first, each numerical value Rn (n = 1 to 5, 8) of each counter (excluding labels-TRND-B2 to B3) is incremented by 1 every time the random number update process is executed. (S15-1) When each numerical value Rn reaches the predetermined maximum value X, it repeats to return to “0” again (S15-2, S15-3). Then, the updated numerical value of each counter is temporarily stored in a random number storage area corresponding to each counter of the RAM of the main control circuit 120A (S15-4). “Rn ′” in FIG. 5 means the value of each counter before addition. As described above, for label-TRND-B2 and label-TRND-B3, numerical values are added at the timing associated with label-TRND-B1, as described above, and the random number storage area of the RAM of main control circuit 120A Is stored in each.

In the start timer update process (S16), the start timer is updated (counted) according to the presence / absence of the special symbol fluctuation hold count and whether or not the special symbol is changing. The start timer is provided in the main control circuit 120A, and counts the time during which the special symbol variation display in the special symbol display unit 42 is continued. This start timer update process (S16) corresponds to the process of the fluctuation display continuous time counting means and the process of the fluctuation display continuous judgment means in the present invention. In this start timer update process (S16), as shown in FIG. 6, it is first determined whether or not the number of special symbol fluctuation hold is greater than “0”, and if it is not greater than “0”, ie, “0”. In addition, it is determined whether or not the changing flag is “1”, that is, whether or not the special symbol is currently in the variable display. If it is determined that the variable symbol is not in the variable display, the special symbol fluctuation display is interrupted. The start timer is cleared, that is, the count value ( counting time) of the variable display continuous time counting means is returned to the initial value ('0' in this embodiment) (S16-3), and this start timer update process ( S16) ends. On the other hand, when the changing flag C1 is 1 in S16-2, that is, it is determined that the current change is being displayed, or in S16-1, the number of special symbol fluctuation hold is larger than “0”, that is, “1” or more. If it is determined that the special symbol fluctuation display is continued, the start timer value is incremented by 1 and updated (S16-4), and the start timer update process (S16) is completed. To do. In addition, in the update of the start timer, since the time when the main process M is repeated (for example, 2 msec) is added as “1”, the update value is an integer value of “1”, “2”, and so on. It is represented by Further, the update value (corresponding to the counting time) of the start timer is used after being converted into time (second unit) when used as a specific variable display continuous time.

  Next, whether the signal input in the sensor input process (S14) is a detection signal by the start winning port detection switch (start winning port sensor) (that is, whether or not the start winning port 10 has been won) and the special symbol variation holding number is 4. It is confirmed whether both of the following are satisfied (S17). If both are satisfied, the special symbol variation holding number is incremented by 1 (S18), followed by random number acquisition processing (S19), and the various updated random number values stored in the RAM of the main control circuit 120A. Q1 to Q7 are read and acquired, and stored in a storage area for acquired random values in the RAM of the main control circuit 120A. If it is determined in S17 that at least one of the detection signal detected by the start winning port detection switch (start winning port sensor) and the special symbol variation holding number 4 is not satisfied, the random number acquisition process (S18). Is not performed, and the process jumps to the next determination condition satisfaction determination (S20). The numerical value Q8 of the label-TRND-H for determining the small hit / stop normal symbol is that the game symbol passes through the normal symbol variation start left gate 19 or the normal symbol variation start right gate 21 and the normal symbol. Acquired when detected by the fluctuation start switch.

  In the determination of whether or not the determination condition is satisfied (S20), it is confirmed whether or not the big hit determination condition is satisfied. The fact that the jackpot winning / failing determination condition is satisfied means that the special game is not currently being executed or the special symbol is not changing, and that the special symbol change hold number is 1 or more. When it is determined that the jackpot winning / failing determination condition is satisfied, the jackpot winning / failing determination process (S21), the reach presence / absence determination process (S22), the fixed stop special symbol determination process (S23), the variation mode determination process (S24), A special symbol fluctuation hold count subtraction process (S25) and a fluctuation process (S26) are executed. On the other hand, if it is determined in S20 that the jackpot determination condition is not satisfied, the process jumps to the changing process (S26).

  In the jackpot determination process (S21), as shown in FIG. 7, the acquired random number value Q1 of the label -TRND-A is compared with the jackpot value “5”, “500” (S21-1), and the acquisition If the random value Q1 is any of the jackpot values, the jackpot is set, the jackpot flag A1 is set to 1, and the jackpot flag A1 (= 1) is stored in the RAM of the main control circuit 120A (S21- 2).

  In the reach presence / absence determination process (S22), it is determined whether or not the special symbol display unit 42 is in a reach state. As shown in FIG. 8, in this reach presence / absence determination process (S22), it is confirmed whether the jackpot flag A1 is 1 (S22-1). If the jackpot flag A1 is not 1 but 0, that is, if the jackpot is not established, the label- The stored acquired random number value Q2 of TRND-R1 is read, and it is determined whether or not the acquired random number value Q2 is '24' or '49' (S22-2). If the acquired random value Q2 is not '24' or '49', it is determined that there is no reach. On the other hand, when the acquired random value Q2 is '24' or '49', it is determined that there is a reach, the reach flag R1 is set to 1, and the reach flag R1 (= 1) is set in the main control circuit 120A. It is stored in the RAM (S22-3). Further, when the jackpot flag A1 is 1 in S22-1, that is, when the jackpot (special game execution is possible), it is determined that there is a reach, the reach flag R1 is set to 1, and the The reach flag R1 (= 1) is stored in the RAM of the main control circuit 120A (S22-3).

  In the fixed stop special symbol determination process (S23), a special symbol to be fixed and stopped on the special symbol display unit 42 is determined based on the jackpot winning / failing determination process (S26). As shown in FIG. 9, in the fixed stop special symbol determination process (S23), first, it is confirmed whether the value of the jackpot flag A1 is 1 (S23-1). When the value of A1 is determined to be 1, that is, when the jackpot (special game execution is possible), the stored acquired random number value Q4 of the label -TRND-AZ1 is read and predetermined with respect to the acquired random number value Q4 The combination of the displayed symbols is determined as the jackpot symbol that is confirmed and stopped on the special symbol display unit 42 (S23-2).

  On the other hand, if the value of the jackpot flag A1 is not 1 in S23-1, that is, if the value is confirmed to be 0 and determined to be out, the stored and acquired random value Q5 of the labels -TRND-B1 to B3 -Q7 are read out, and it is determined whether or not the obtained random numbers Q5 to Q7 match (S23-3). If the acquired random numbers Q5 to Q7 match, it is subsequently determined whether or not there is a reach (unreach). Here, it is confirmed whether or not the reach flag R1 is 1 (S23-4). If it is determined that there is no reach, the obtained random number value Q6 of the label-TRND-B2 (for right special symbol) is incremented by 1, and the obtained value and the obtained random number values Q5, Q7 of the labels-TRND-B1, B3 are added. On the other hand, a predetermined symbol is determined as an off symbol composed of a left special symbol, a middle special symbol, and a right special symbol that are confirmed and stopped displayed on the special symbol display unit 42 (S23-5). On the other hand, if it is determined in S23-4 that there is a reach, the obtained random number Q7 of the label-TRND-B3 (for medium special symbol) is incremented by 1, and the value and the labels-TRND-B1, B2 are obtained. A predetermined symbol for the random number values Q5 and Q6 is determined as a deviated symbol to be confirmed and stopped (S23-6).

  If at least one of the obtained random number values Q5 to Q7 of the labels -TRND-B1 to B3 is a different numerical value in S23-3, the obtained random number value Q5 of the label -TRND-B1 and the label -TRND It is determined whether or not the acquired random value Q6 of -B2 matches (S23-7), and if both values match, it is further determined whether or not there is a reach (S23-8). When there is no reach, the obtained random number value Q6 of the label-TRND-B2 is incremented by 1, and the predetermined pattern for the obtained random number values Q5, Q7 of the labels-TRND-B1, B3 is It is determined as an off symbol to be confirmed and stopped (S23-5). On the other hand, if there is a reach, a predetermined symbol for the acquired random number values Q5 to Q7 of labels -TRND-B1 to B3 is determined as an out symbol to be displayed in a fixed stop (S23-9).

  Further, if the acquired random value Q5 of label-TRND-B1 and the acquired random value Q6 of label-TRND-B2 do not match in S23-7, it is subsequently determined whether or not there is a reach (S23-10). When it is determined that there is a reach, the acquired random value Q6 of the label -TRND-B2 is forcibly changed to the same numerical value as the acquired random value Q5 of the label -TRND-B1, and the label -TRND-B3 The acquired random number value Q7 is forcibly changed to a value obtained by adding 1 to the acquired random number value Q5 of the label-TRND-B1, and these numerical values and the acquired random value Q5 of the label-TRND-B1 are determined in advance. The symbol is determined as an off symbol to be confirmed and stopped (S23-11). On the other hand, if it is determined in S23-10 that there is no reach, the symbols predetermined for the acquired random numbers Q5 to Q7 of labels -TRND-B1 to B3 are confirmed and stopped in each display area. It is determined as a symbol (S23-9). The symbols determined as described above are stored in the command buffer of the main control circuit 120A (S23-12).

  In the variation mode determination process (S24), the selection process of the variation mode (variation display time) of the special symbol is performed using the time during which the variation display of the special symbol in the special symbol display unit 42 continues as a determination material. In this case, the reference variation display time is subtracted from the start timer. This variation mode determination process (S24) corresponds to the processing of the selection unit, the variation display continuous time comparison unit, the subtraction unit, and the variation display time selection rate switching unit in the present invention.

  In the variation mode determination process (S24), as shown in FIG. 10, it is first confirmed whether the jackpot flag A1 is 1 (S24-1). When the jackpot flag flag A1 is 1, that is, when the jackpot is a jackpot variable display time selection process (S24-2). In the jackpot variation display time selection process (S24-2), the jackpot hour selection table shown in Table 1 is selected, and the value of the obtained random number value Q3 of the variation mode selection label -TRND-T1 is selected. Thus, one variation mode is selected from the variation modes 13 to 17 of the jackpot time selection table. That is, when the acquired random number value Q3 of the label -TRND-T1 is' 0 to 15 ', the variation mode 13 having a variable display time of 10 seconds is selected, and when the acquired random number value Q3 is '16 to 25'. When the variation mode 14 with a variation display time of 11 seconds is selected, and when the acquired random number value Q3 is '26 to 30 ', the variation mode 15 with a variation display time of 11.5 seconds is selected, and the acquired random number value Q3 is' In the case of 31 to 34 ', the variation mode 16 with a variation display time of 3 seconds is selected, and when the obtained random number Q3 is' 35', the variation mode 17 with a variation display time of 15 seconds is selected. In the jackpot variation display time selection process, a variation mode determination command for designating the selected variation mode (variation display time and variation method) is set in the command buffer of the main control circuit 120A, and the special control mode is selected. The variation timer for counting the variation display elapsed time of the special symbol in the symbol display unit 42 is set to start counting. Thereafter, the big hit flag A1 and the reach flag R1 are set to 0 (S24-8), and the changing flag C1 is set to 1 (S24-9), and the changing mode determination process (S24) is completed.

  On the other hand, when the jackpot flag A1 is 0 instead of 1, that is, when it is off, the value of the start timer and the reference fluctuation display time, that is, the fluctuation display continuous time (counting by the fluctuation display continuous counting means in the present invention) Time) and the reference variation display time (5 seconds in this embodiment) are compared, and it is determined whether the value of the start timer is equal to or shorter than the reference variation display time (5 seconds in this embodiment) (S24-3).

  When the value of the start timer is not less than or equal to the reference variation display time, that is, when the counting time of the variation display continuous time is longer than the reference variation display time (5 seconds in this embodiment), the short variation display time is selected. (S24-4). In the short variation display time selection process (S24-4), the short variation display time high selection ratio selection table shown in Table 1 is selected, and the presence / absence of reach and the variation mode selection label -TRND-T1 are selected. One variation mode is selected from the variation modes 1 to 6 in the short variation display time high selection rate selection table according to the combination of the acquired random value Q3. That is, when the reach flag R1 is 0 (no reach), the variation mode 1 having a variation display time of 2 seconds is selected regardless of the value of the acquired random value Q3 of the label -TRND-T1, and the reach flag R1 is In the case of 1 (with reach), when the value of the acquired random value Q3 of the label -TRND-T1 is '0 to 15', the variation mode 2 with a variation display time of 3 seconds is selected, and the acquired random value Q3 When the value is '16 to 25 ', the variation mode 3 with a variation display time of 3.5 seconds is selected, and when the value of the obtained random number Q3 is '26 to 30', the variation mode 4 with a variation display time of 4 seconds. Is selected, the variation mode 5 with a variable display time of 5 seconds is selected when the value of the acquired random value Q3 is '31 to 34 ', and the variable display time is when the value of the acquired random number Q3 is' 35'. The variation mode 6 of 10 seconds is selected, and the selected variation state A variation mode determination command for designating (variable display time and variation method) is set in the command buffer of the main control circuit 120A, and a variation timer for counting variation display elapsed time of the special symbol in the special symbol display unit 42 Is set to start counting.

  When the value of the start timer is equal to or shorter than the reference fluctuation display time, that is, when the counting time of the fluctuation display continuous time is equal to or shorter than the reference fluctuation display time (5 seconds in this embodiment), the long fluctuation display time Is selected (S24-6). In the long variation display time selection process (S24-6), the long variation display time high selection ratio selection table shown in Table 1 is selected, and the presence / absence of reach and the variation mode selection label -TRND-T1 are selected. One variation mode is selected from the variation modes 7 to 12 in the selection table for the long variation display time high selection rate according to the combination of the acquired random value Q3. That is, when the reach flag R1 is 0 (no reach), the variation mode 7 with the variation display time of 8 seconds is selected regardless of the value of the acquired random number Q3 of the label -TRND-T1, and the reach flag R1 is In the case of 1 (with reach), when the value of the acquired random value Q3 of the label -TRND-T1 is '0 to 15', the variation mode 8 with a variation display time of 9 seconds is selected, and the acquired random value Q3 When the value is '16 to 25 ', the variation mode 9 with the variation display time of 11 seconds is selected, and when the value of the obtained random number Q3 is '26 to 30', the variation mode 10 with the variation display time of 11.5 seconds is selected. Is selected, the variation mode 11 having a variation display time of 12 seconds is selected when the value of the obtained random number Q3 is '31 to 34 ', and the variation display time is obtained when the value of the acquired random number Q3 is' 35'. The 3 second variation mode 12 is selected and selected. A variation mode determination command for designating a variation mode (a variation display time and a variation method) is set in the command buffer of the main control circuit 120A, and the special symbol display unit 42 is used for counting the variation display elapsed time of the special symbol. The variable timer is set to start counting.

  After the short variation display time selection process (S24-4) and the long variation display time selection process (S24-6), the reference variation display time is subtracted from the value of the start timer, that is, the variation display continuous time The reference fluctuation display time is subtracted from the counting time to update the counting time of the fluctuation display continuous time (S24-5, S24-7), and then the big hit flag A1 and the reach flag R1 are set to 0 (S24-8). ) And the changing flag C1 are set to 1 (S24-9), and the changing mode determining process (S24) is completed.

  After the variation mode determination process (S24), a special symbol variation suspension number subtraction process is performed (S25) in which 1 is subtracted from the special symbol variation suspension number.

  In the changing process (S26), a process when the special symbol is changing is performed. In the changing process (S26), as shown in FIG. 11, it is first determined whether the changing flag C1 is 1, that is, whether the current special symbol is changing (S26-1), and the changing flag C1 is not 1. That is, if the special symbol is not currently being displayed in a changing manner, the changing processing (S26) is terminated. On the other hand, if the changing flag C1 is 1, that is, if the current special symbol is being changed, the change timer is greater than 0, that is, the change indication of the change mode selected in the change mode determination process (S24). It is determined whether the time has expired (S26-2). If the variation timer is greater than 0, that is, if the variation display time has not expired, 1 is subtracted from the variation timer to update the variation timer (S26-3), and this variation processing (S26) is terminated. . On the other hand, when the variation timer is not greater than 0, that is, when the variation display time has expired, the variation flag C1 is set to 0 (S26-4), and the variation stop flag D1 is further set to 1. (S26-5), and this in-fluctuation processing (S26) ends.

As shown in FIG. 12, in the fluctuation stop process (S27), first, it is determined whether the fluctuation stop flag D1 is 1 (S27-1). If the fluctuation stop flag D1 is not 1, that is, the fluctuation display time ends. If not, the fluctuation stop process (S27) ends. On the other hand, when the variation stop flag D1 is 1, that is, when the variation display time has ended (elapsed), processing for setting variation stop data such as a stop symbol command for stopping the variation of the special symbol or a symbol stop command (S27) -2) is performed, and the variable stop flag D1 is set to 0 (S27-3), and then it is determined whether the stop symbol of the special symbol is a jackpot symbol (in the present embodiment, a rough eye) (S27-). 4). When the stop symbol is a big hit symbol, the big hit middle flag A2 is set to 1 (S27-5), and this variation stop processing (S27) is ended. If it is determined that the stop symbol is not a jackpot symbol, the variation stop processing (S27) ends at that time.

  In the jackpot process (S28), a process related to the control of the gaming machine in the jackpot is performed. As shown in FIG. 13, in the jackpot processing (S28), it is first determined whether the jackpot flag A2 is 1, that is, whether the jackpot is being hit (S28-1), and the jackpot flag A2 is not 1, that is, the jackpot is not being hit. In this case, the jackpot process (S28) ends.

  On the other hand, when the big hit flag A2 is 1, that is, the big hit, it is confirmed whether 10 game balls have entered the big winning opening 15 (S28-2), and 10 game balls have not entered. In this case, it is determined whether the opening state of the open / close plate 16 of the special winning opening 15 has passed a preset opening time (for example, 29.5 seconds) (S28-3), and the opening time has not elapsed. In this case, the jackpot process (S28) is completed, and when the opening time has elapsed, the big prize closing process (S28-4) is performed next. If 10 game balls have entered the winning prize opening 15 in S28-2, the determination of the elapse of the opening time (S28-3) is jumped to the next winning prize closing process (S28-4). ) Is performed.

  In the display control process (S30), it is first determined whether or not the power is turned on this time (S31). If the power is turned on this time, an initial setting process (S32) is performed.

  In the initial setting process (S32), stack setting, interrupt time setting (2.0 msec in this example), CPU setting, SIO, PIO, CTC setting and the like are performed. The initial setting process (S32) is a process that is necessary only when the power is turned on, and is executed only in the first round, and thereafter, the process proceeds to the next command reception process (S33) without being executed.

  In the command reception process (S33), as shown in FIG. 15, it is confirmed whether or not the command transmitted from the main control circuit 120A has been received (S33-1).

  When the confirmation flag is 1, a process of creating image data at the time of symbol confirmation stopped and displayed on the special symbol display unit 42 is performed (S34-4), and the confirmation flag is set to 0 (S34). -5) After that, the created image data is stored in the buffer of the display control circuit 130A (S34-11), and then the image data creation process (S34) ends.

  On the other hand, if the variable display flag is 1, it is further confirmed whether the image data counter is the final value (S34-3). The image data counter is provided in the display control circuit 130A, and is used to display an image corresponding to the counter value on the special symbol display unit 42 as a changing image. ), The final image at the time of change is displayed. If the image data counter is not the final value, the image data that is changing is created (S34-6), and 1 is added to the value of the image data counter (S34-7), and then the created image data is displayed. The data is stored in the buffer of the control circuit 130A (S34-11), and then the image data creation process (S34) ends. On the other hand, if the image data counter is the final value, the final image data that is changing is created (S34-8), and the changing flag is set to 0 (S34-9). The data is stored in the buffer of the display control circuit 130A (S34-11), and then the image data creation process (S34) ends.

  If neither the confirmation flag nor the changing flag is set to “1”, other data is created (S34-10), and the created image data is stored in the buffer of the display control circuit 130A. (S34-11), and then the image data creation process (S34) ends.
