Here, description of various components (not shown) other than the game board 14, the spacer 31, and the liquid crystal display device 32 is omitted to facilitate understanding.

  The game board 14 is a transparent game board, and is entirely formed of a plate-shaped resin material (a member having permeability) having transparency. Examples of the transparent member include various materials such as acrylic resin, polycarbonate resin, and methacrylic resin. In addition, the game board 14 has a game area 15 on the front side thereof in which the launched game ball can roll. The game area 15 is an area surrounded by the guide rail 30 and allowing the game ball to roll. In addition, a plurality of game nails 13 are driven into the game area 15 of the game board 14.

  The liquid crystal display device 32 is provided behind the game board 14 with the spacer 31 interposed therebetween. In other words, the liquid crystal display device 32 is disposed behind the transparent member of the game board 14. The liquid crystal display device 32 has a display area 32a that enables display of an image relating to a game. The display area 32a is disposed so as to overlap the whole or a part of the game board 14 from the back side with the spacer 31 interposed therebetween. Specifically, the liquid crystal display device 32 is disposed behind the game board 14 so that the display area 32 a overlaps all or part of the game area 15 and all or part of the game area outer area 16. . Various images such as effect images and decoration images are displayed in the display area 32 a of the liquid crystal display device 32.

  Further, by providing the liquid crystal display device 32 behind the transmissive area in the game board 14, for example, the area for providing the game member such as an obstacle nail planting area, an accessory, or a decorative member is increased, and the degree of freedom in layout is also increased. It can be made even larger.

  The spacer 31 is disposed on the rear side (back side) of the game board 14 and on the front side (front side) of the liquid crystal display device 32. The spacer 31 is made of a permeable material, and has a large through hole 31a at the center. An electrical decoration unit 53 to be described later is provided on the upper portion of the through hole 31a.

  As described above, the gaming board 14 is disposed inside the opening 12a of the gaming machine frame 12, but in the above-described configuration, in the present embodiment, the gaming machine frame 12 moves the gaming board 14 to the gaming board frame 12. A holding means that is movably held and a detection means that detects the movement of the game board 14 are provided, and based on the detection result by the detection means, an illegal act placed on the game board 14 can be detected.

  FIG. 3 is a schematic explanatory view showing the structure of the holding structure of the game board 14 and the detection means. As shown in FIG. 3, sensor housing recesses Q are formed at four locations on the inner surface of the rectangular gaming machine frame 12, and one ends of the sensor housing recesses Q are fixed to the gaming machine frame 12 side. Pressure sensors 27a, b, 28a, b also serving as game board holders are arranged via coil springs S, and the game board 14 is fixedly supported by the pressure sensors 27a, b, 28a, b also serving as game board holders. It is supported in a floating state.

  With this configuration, the game board 14 is elastically held so that it can be moved minutely up and down, left and right, and the total weight of the game board 14 and an external load can be detected by 27a, b, 28a, b. It becomes. Further, there are cases where the weight of the game board 14 changes depending on the game ball launched during the game, and the fluctuation can be detected at any time.

  In this embodiment, the pressure sensors 27a, b, 28a, and b are employed as the detection means. However, any type may be used as long as it is a sensor for detecting the movement of the game board 14 held movably. For example, an acceleration sensor that can detect the movement of the game board 14 may be used.

  In addition, the movement data of the game board 14 acquired by the pressure sensors 27a, b, 28a, b becomes a reference in a predetermined storage area such as a main ROM 68 (see FIG. 6) provided in the main control circuit 60 described later. Usually stored as motion data. Note that the current normal motion data is measured and acquired in such a manner that the current normal motion data is sequentially taken into a predetermined storage area such as the main RAM 70 (see FIG. 6) provided in the main control circuit 60 at every time determined by the built-in timer. The current movement data of the game board 14 may be stored as the latest data.

  As will be described in detail later, the main control circuit 60 compares the data relating to the detection results by the pressure sensors 27a, b, 28a, b with the normal motion data that is stored in advance as a reference, and the main control circuit 60 It is determined whether or not there is an abnormality in a change in movement (appears as a change in weight or pressure), and the determination result is given to the liquid crystal display device 32 described above, decorative lamps 133a and 133b described later, speakers 46L and 46R, or the like. As notification means, they are used to notify the outside.

  Next, the special symbol display 33, the normal symbol display 35, the special symbol hold lamps 34a to 34d, and the normal symbol hold lamps 50a to 50d will be described with reference to an enlarged view of the illumination unit 53 shown in FIG.

  As shown in FIG. 4, the special symbol display 33 accommodated in the display unit case 37 is composed of a 7-segment LED 41, and is repeatedly turned on and off when a predetermined special symbol variable display start condition is satisfied. Thus, 10 numeric symbols from “0” to “9” are variably displayed as special symbols.

  The gaming state of the pachinko gaming machine 10 according to the present embodiment can be broadly classified into a general gaming state (a game ball is consumed while performing a lottery lottery, a so-called disadvantageous state for a player) and a jackpot gaming state (a short time for the player). Thus, a large amount of game balls can be expected, which is a so-called advantageous state for players.

  Furthermore, according to a specific numerical symbol that is randomly displayed in the special symbol display 33, which is selected in the special symbol control process described later, the 15R probability variable big hit gaming state, the 2R probability variable big hit gaming state, or the 15R normal big hit gaming state, Three types of jackpot gaming states are determined. And after each jackpot game state is complete | finished, the said general game state also transfers to the general game state of a state different from probability change mode or time-shortening mode.

  In other words, when a specific numeric symbol (for example, a numeric symbol of “7”) is stopped and displayed as the special symbol, a round game advantageous to the player from the general gaming state is continuously performed up to 15 times. Transition to jackpot gaming state. In addition, when a specific numerical symbol (for example, a numerical symbol of “3”) is stopped and displayed, the 2R probability variable big hit gaming state in which the round game advantageous to the player is continuously performed twice at maximum from the general gaming state. Transition. Then, after the end of the big hit gaming state, the mode shifts to a probability change mode, which is a general gaming state in which the probability of changing to the big hit gaming state is higher than usual. When a specific numerical symbol (for example, a numerical symbol of “5”) is stopped and displayed, a transition is made from the general gaming state to a 15R normal jackpot gaming state in which a round game advantageous to the player is continuously performed up to 15 times. . Then, after the big hit gaming state ends, the mode shifts to the time saving mode which is the general gaming state. At this time, the short mode is shifted to the normal mode (the most basic general game state in the pachinko gaming machine 10), which is a general game state, when the number of changes (for example, 100 times) of the special symbol is digested.

  On the other hand, as a special symbol, if a numeric symbol other than a specific numeric symbol (for example, a numeric symbol other than “3”, “5”, or “7”) is stopped and displayed, the general gaming state basically shifts. do not do. However, the details will be described in the special symbol control process described later. When the general gaming state is the short-time mode, the general gaming state is determined when the number of variations of the special symbol has reached a predetermined variation number (for example, 100 times). Is switched from the short-time mode to the normal mode. As described above, a game in which a special symbol is variably displayed and then stopped and the game state is shifted or maintained depending on the result is called a “special symbol game”.

  Further, on both the left and right sides of the display case 37, special symbol holding lamps 34a to 34d are provided. The special symbol hold lamps 34a to 34d display the number of executions of the special symbol variation display held by turning on or off (so-called “number of special symbols on hold ball”). Here, the upper limit of the number of reserved balls is four.

  A normal symbol display 35 is provided on the right side of the special symbol display 33. The normal symbol display 35 is composed of two display lamps (not shown). When these display lamps are alternately turned on and off, symbols such as “O” and “X” are displayed. Fluctuated display as a normal symbol.

  Under the display case 37, normal symbol holding lamps 50a to 50d are provided. The normal symbol hold lamps 50a to 50d display the number of executions of the normal symbol variation display held by turning on or off (so-called “normal symbol hold ball number”). Again, the upper limit of the number of reserved balls is four.

  The description of the overview of the pachinko gaming machine 10 using FIG. 1 and FIG. 2 is continued. Decorative lamps 133a and 133b as light emitting display means are arranged outside the transmissive area of the game board 14, and display a predetermined light emission mode according to the gaming state. As described above, the decorative lamps 133a and 133b may function as notification means for notifying that an illegal act has been performed.

  A protective plate 19 having transparency is disposed on the door 11. The protection plate 19 is disposed so as to face the front surface of the game board 14 with the door 11 closed.

  The launch handle 26 is provided so as to be rotatable with respect to the gaming machine frame 12. A firing solenoid (not shown) as a driving device is provided on the back side of the firing handle 26. Further, a touch sensor is provided on the peripheral edge of the firing handle 26. When the touch sensor is touched by the player, it is detected that the firing handle 26 is gripped by the player. When the firing handle 26 is gripped by the player and is rotated in the clockwise direction, power is supplied to the firing solenoid according to the rotational angle, and the game ball stored in the upper plate 20 is played. It is fired sequentially on the board 14 and the game proceeds.

  In the display area 32a of the liquid crystal display device 32 disposed behind (on the back side of) the game board 14, an effect image related to the special symbol displayed on the special symbol display 33 is displayed.

  For example, during the variable display of the special symbol displayed on the special symbol display device 33, in the display area 32a of the liquid crystal display device 32, a decorative symbol (even identification information for production) is formed of a single symbol row in a single symbol row. For example, “0” to “9” are displayed in a variable manner. In addition, the special symbol that has been variably displayed on the special symbol display 33 is stopped and displayed, and the decorative symbol for effect is also stopped and displayed on the display area 32 a of the liquid crystal display device 32.

  When a special numerical symbol is stopped and displayed as a special symbol on the special symbol display 33, an effect image that allows the player to grasp that it is a big hit is displayed in the display area 32a of the liquid crystal display device 32. Specifically, when a specific numeric symbol is stopped and displayed as a special symbol on the special symbol display 33, a combination of effect decorative symbols displayed in the display area 32a of the liquid crystal display device 32 is a specific display. This is a mode (for example, a mode in which all of “1” to “9” are stopped and displayed).

  As a combination of the decorative symbols for performance, when the specific “odd” number symbols are all stopped and displayed (for example, “111” to “999” number symbols), the game is started from the general gaming state. The game shifts to a 15R probable big hit game state in which a round game advantageous to the user is continuously performed up to 15 times. In this case, the specific symbol displayed on the special symbol display 33 is “7”. In addition, when a specific numerical symbol is stopped and displayed with a serial number (for example, a numerical symbol of “1”, “2”, “3”), a round game advantageous to the player from the general gaming state continues at most twice. The 2R probability variation big hit gaming state is performed. In this case, the specific symbol displayed on the special symbol display 33 is “3”. Furthermore, when a specific “even” number symbol is all displayed and stopped (for example, “222” to “888” number symbol), the round game that is advantageous to the player from the general gaming state is the largest. Transition to the 15R normal jackpot gaming state, which is continuously performed 15 times. In this case, the specific symbol displayed on the special symbol display 33 is “5”. As described above, the combination of the decorative symbols corresponding to the specific symbols stopped and displayed on the special symbol display 33 is stopped and displayed in the display area 32 a of the liquid crystal display device 32.

  In addition, when the combination of effect decorative symbols displayed in the display area 32a of the liquid crystal display device 32 is in a specific display mode, a character that is more than happy with a character image such as “big hit!”. An image is displayed in the display area 32 a of the liquid crystal display device 32.

  As described above, in the pachinko gaming machine 10 according to the present embodiment, when a game ball enters the start port 25, a lottery is performed as to whether or not to shift to a game advantageous to the player, and a special symbol display is performed. The display unit 33 displays a variation of the identification symbol, and the liquid crystal display device 32 performs a variation display of the decorative symbol as an effect and an accompanying effect display.

  Next, with reference to FIG. 5, the overview of the pachinko gaming machine 10 will be further described.

  The pachinko gaming machine 10 according to the present embodiment has the above-described configuration, and can detect fraudulent acts performed on the game board 14 and notify them of this. In the following, a description will be given of how the game board 14 is detected and notified when an illegal act is actually made.

  FIG. 16 is a comparative explanatory view of normal motion data of the game board 14 and data indicating abnormality, and FIG. 17 is an explanatory view showing a notification mode for fraud.

  The data shown in FIG. 16A is stored in advance in the main ROM 68 of the main control circuit 60 when the pachinko gaming machine 10 is shipped from the factory, and the pressure value σx loaded in the normal state in the horizontal direction of the game board 14. Is shown. Also, the data shown in FIG. 16C is stored in advance in the main ROM 68 of the main control circuit 60 when the pachinko gaming machine 10 is shipped from the factory, and is loaded in the normal state in the vertical direction of the game board 14. The pressure value σy is shown.

  On the other hand, the data shown in FIG. 16 (b) is obtained by using the pressure sensors 27a and 27b that detect the movement of the gaming board 14 in the horizontal direction in the horizontal direction. It is data indicating movement. In addition, the data shown in FIG. 16 (d) is obtained by using the pressure sensors 28a and 28b that detect the vertical movement of the game board 14 in the vertical direction of the latest game board 14 obtained at any given time. It is data indicating movement. As described above, the time series data of the pressure values σx, σy at the time t is stored in the main RAM 70 of the main control circuit 60 by the pressure sensors 27a, b, 28a, b.

  For example, a player may attempt to bend a game nail by intruding a fraudulent tool in which a wire or a flexible longitudinal thin plate is processed into the game board 14 or force the shutter 40 of the prize winning port 39. When it is intended to be opened, a corresponding pressure is applied to the game board 14. Then, the game board 14 held in the floating state moves in the direction in which the pressure is applied.

  As a detection result of the pressure sensors (27a, b, 28a, b) in that case, as shown in FIG. 16 (b) and FIG. 16 (d), data (Ex, Ey) appears.

  The data (Ex, Ey) indicating the abnormal movement appearing as the measurement results of σx and σy is determined by the pressure determination circuit 65 in the main control circuit 60 (see FIG. 6) serving as the pressure determination means, and the determination result is abnormal. If it is determined, as shown in FIG. 17, a notification image 92 is displayed on the display area 32 a of the liquid crystal display device 32 to notify that an abnormality has occurred in the game board 14. Alternatively, as shown in the drawing, an alarm sound, a siren, or the like may be output from the speakers 46L and 46R, or the decorative lamps 133a and 133b may be caused to emit light with a special color or may be caused to emit light with a special blink.

  Note that the notification image 92 indicating the abnormality shown in FIG. 17 may be set as appropriate, and for example, a caption such as “Detecting fraudulent activity!” May be displayed by text. Further, output sounds from the speakers 46L and 46R, light emission patterns of the decoration lamps 133a and 133b, and the like may be determined as appropriate.

  By making such a notification mode, even if a fraudulent act is performed in any of the pachinko gaming machines 10 installed in the game hall or the like, it will be immediately revealed, so that a quick response is possible. It becomes possible. In addition, fraudulent acts are less likely to be performed on the pachinko gaming machine 10 having such a configuration, and an effect of preventing the fraudulent acts is also caused.

  Further, the pachinko gaming machine 10 according to the present embodiment includes an output terminal as output means for outputting the determination result by the pressure determination circuit 65 to the outside of the gaming machine, and the main control circuit 60 and the output terminal via the output terminal. The hall computer H of the amusement hall is connected (see FIG. 6). With this configuration, when the determination result by the pressure determination circuit 65 indicates that the movement of the game board 14 is different from the normal state, or when it is determined that a predetermined pressure is applied, the hall computer H has an abnormality in the game board 14. A signal indicating the occurrence is output, and a display indicating abnormality is displayed on the monitor screen of the hall computer H to notify the game hall manager. The signal output from the output terminal may be wireless or wired.

  As described above, in this embodiment, the pachinko gaming machines 10 arranged in a large number in the hall can be centrally managed via the signals from the respective output terminals on the game hall side, and the occurrence of fraud and gaming machines can be performed. It is possible to respond promptly and accurately to malfunctions.

  By the way, when the pressure sensors 27 and 28 detect the measurement values of the abnormal pressure values σx and σy, the pressure determination circuit 65 exceeds the threshold value stored in the main ROM 68 (see FIG. 6). If it is determined that the movement of the game board 14 is different from the normal movement, the liquid crystal display device 32, the speakers 46L and 46R, the decoration lamp 133a, 133b is used for notification and a signal indicating the occurrence of abnormality is output to the hall computer H.

  Note that the threshold value serving as a determination criterion can be set as normal data by statistically calculating, for example, the average value or deviation of the pressure values σx and σy within a predetermined measurement period regarded as a normal operating state. Based on the average value and deviation of σx and σy within the specified measurement time, it can be determined by hypothesis testing with a predetermined significance level whether it differs from that of normal data, or a normal level that is simply a threshold value Whether or not there is an abnormality can be determined depending on whether the range is exceeded. In addition, a correlation coefficient serving as an index of the strength of the relationship between the pressure values σx and σy in the vertical and horizontal directions may be calculated so that it can be detected as a specific fraud pattern.

Thus, when an abnormal load is applied to the game board 14 due to an illegal act, a caption for notifying the abnormality is displayed largely on the front surface of the display area 32a. Can be found. In addition, it is possible to prevent the occurrence of losses due to fraudulent activity by raising alertness to the player who intends to perform fraudulent activity and making execution of the fraudulent activity difficult.

  First, as shown in FIG. 9, the main CPU 66 executes a random number update process so as to increase the count values of the big hit determination random number counter, the big hit symbol determination random number counter, and the like by “1” (step S21). Then, the main CPU 66 executes an input detection process for detecting a winning of a game ball by various detection sensors such as the start port 25 (step S22). In this processing, the main CPU 66 stores in the predetermined area of the main RAM 70 data for paying out the game balls (winning the game balls) on the condition that the game balls have won the various winning ports. Various types of timers such as a waiting time timer for synchronizing the main control circuit 60 and the sub control circuit 200, a big prize opening timer for measuring the opening time of the big prize opening 39 that is opened when a big hit occurs, etc. The timer update process is executed (step S23). Then, an output process is executed in order to supply a signal for drive control based on various variables to a solenoid, a motor or the like (step S24). If this process ends, the process moves to a step S25.

  In step S25, command output processing is executed. In this processing, the main CPU 66 supplies various commands to the sub control circuit 200 and the like. Specifically, these various commands include a demo display command, a derived symbol designation command indicating the type of special symbol derived and displayed, a weight change of the game board 14 and an abnormal state accompanying detection of a falling nail. Game state notification commands and the like. If this process ends, the process moves to a step S26.

In step S26, the main CPU 66 executes a payout process such as transmitting a prize ball control command for causing the payout device 128 to perform a prize ball to the payout / firing control circuit 126. Specifically, the main CPU 66 supplies to the payout / launch control circuit 126 a prize ball control command for paying out a predetermined number of prize balls as a result of the game balls winning in various winning holes. When this process is finished, this subroutine is finished, the address is returned to the address before the occurrence of the interrupt, and the main process is executed.
[Special symbol control processing]
The special symbol control process executed in step S12 of FIG. 8 will be described with reference to FIG.

  First, in the process of step S31, the main CPU 66 loads a special symbol control flag. In this process, the main CPU 66 reads the special symbol control flag and moves the process to step S32.

  In step S32, the main CPU 66 determines whether or not the special symbol control flag is (00). If the special symbol control flag is not (00), the main CPU 66 proceeds to step S34. If the special symbol control flag is (00), the process proceeds to step S33 to perform a special symbol storage check process. As will be described in detail later, in this special symbol memory check process, the number of reserved special symbols is checked, and if there is a reserved number, a “big hit” lottery, special symbol variation start, special symbol variation timer is set, etc. Then, (01) which is the processing request for the next step is set in the special symbol control flag, and the processing is terminated.

  In step S34, the main CPU 66 determines whether or not the special symbol control flag is (01). If the special symbol control flag is not (01), the main CPU 66 shifts the processing to step S40. When the special symbol control flag is (01), special symbol variation time monitoring processing is performed. That is, in step S35, it is determined whether or not the special symbol variation timer is up (that is, “0”). If the time is not up, the process is terminated. When the time is up, the main CPU 66 performs a special symbol stop process in step S36 and updates the special symbol holding number stored in the main RAM 70 so as to decrease by "1". Further, the main CPU 66 determines whether or not the game state flag is in the time reduction mode. If the game time flag is in the time reduction mode, the main CPU 66 updates the memory so that the number of time reductions stored in the main RAM 70 is decreased by “1”. When it becomes 0 "(that is, the end of the time reduction mode), the gaming state flag is set to the normal mode, and the time reduction mode is ended.

  Next, the main CPU 66 determines whether or not the special symbol is a big hit in step S37. If not, the main CPU 66 clears the special symbol control flag in step S39 (that is, the value (00) for requesting the special symbol storage check process). Set) to finish the process. If the special symbol is a big hit, a special winning opening release waiting process in step S38 is performed. In the special winning opening release waiting process, the main CPU 66 sets a value (02) indicating waiting for the special winning opening to the special symbol control flag, and sets a waiting time (for example, 1 second) in the special winning opening release waiting timer. End the process.

  In step S40, the main CPU 66 determines whether or not the special symbol control flag is (02). If the special symbol control flag is not (02), the process proceeds to step S43. When the special symbol control flag is (02), a special winning opening release process is performed. In the special prize opening process, first, the main CPU 66 determines in step S41 whether the special prize opening waiting timer is timed up (that is, “0”). If the time is not up, the process is terminated. If the time is up, a special winning opening opening process is performed in step S42. In this special winning opening opening process, the main CPU 66 first sets the opening of the special winning opening (stores the opening instruction of the special winning opening solenoid 120 by the shutter 40 in a predetermined area of the main RAM 70), and then the big win. Depending on the type, the opening time of the big prize opening is set in the big prize opening timer (for example, 30 seconds if the jackpot is 15R probability variation jackpot, or 15R normal jackpot, or 1 second if 2R probability variation jackpot). Then, the special symbol control flag is set to a value (03) indicating the special winning opening release monitoring process, and the process ends.

  In step S43, the main CPU 66 determines whether or not the special symbol control flag is (03). If the special symbol control flag is not (03), the main CPU 66 proceeds to step S50. When the special symbol control flag is (03), a special winning opening opening monitoring process is performed. In the big prize opening monitoring process, first, the main CPU 66 determines whether or not the big prize opening timer has timed out (that is, “0”) in step S44 or whether or not a predetermined number of game balls have won the big prize opening. Determine whether. Then, the time of the grand prize opening timer expires, and at the same time, if the prescribed number of game balls have not won the big prize opening, the process is terminated. Then, the process proceeds to step S45 when the winning opening timer expires or when a prescribed number of game balls satisfy the winning condition.

  In step S45, the main CPU 66 executes a special winning opening closing process (stores a closing instruction of the special winning opening solenoid 120 by the shutter 40 in a predetermined area of the main RAM 70), and moves the process to step S46.

  In step S46, the main CPU 66 counts the number of times that the special winning opening is opened (the so-called number of rounds), and whether or not the specified number of times (15 times for the 15R normal jackpot or 15R probability variation jackpot, 2 times for the 2R probability variation jackpot) has been reached. In step S49, the special symbol control flag is set to a value (04) for requesting the jackpot end process, and the process ends. On the other hand, if the number of times of opening of the big winning opening has not reached the prescribed number, the main CPU 66 determines whether or not the game ball that won the big winning opening has passed a predetermined specific area in step S47. If the game ball that has won the winning opening does not pass through the predetermined specific area (when the V / count sensor 102 does not detect the passing of the game ball), the special symbol control flag is subjected to jackpot end processing in step S49. The requested value (04) is set and the process is terminated. On the other hand, the main CPU 66 moves the process to step S48 when the game ball that has won the special winning opening passes a predetermined specific area (that is, the V / count sensor 102 detects the passage of the game ball).

  In step S48, the main CPU 66 performs a special winning opening opening waiting process. In the special winning opening release waiting process, the special symbol control flag is again set to the value (02) for requesting the opening of the special winning opening, and the waiting time (for example, 1 second) is set in the special winning opening release waiting timer. finish.

In step S50, the main CPU 66 performs jackpot end processing. In the jackpot end process, when the jackpot symbol is 15R probability variation jackpot or 2R probability variation jackpot, the gaming state flag is set to the probability variation mode, and when the jackpot symbol is 15R regular jackpot, the gaming state flag is set to the time reduction mode, and further in the time reduction mode. The upper limit (for example, 100 times) of the variation number of the special symbol is stored in a predetermined area of the main RAM 70. Finally, the main CPU 66 clears the special symbol control flag (that is, sets a value (00) for requesting the special symbol storage check process), and ends the special symbol control process.
[Special symbol memory check processing]
The special symbol memory check process executed in step S33 in FIG. 10 will be described with reference to FIG.

  First, in step S61, the main CPU 66 determines whether or not the number of special symbol reservations is “0”. If the number of special symbol reservations is “0”, the main CPU 66 moves the process to step S62. If the number of symbols held is not “0” (that is, if there is a special symbol variation), the process proceeds to step S63.

  In step S62, a demonstration display process is executed. In this process, the main CPU 66 stores data for supplying a demo display command to the sub-control circuit 200 in a predetermined area of the main RAM 70 in order to perform a demo display. As a result, the sub-control circuit 200 can recognize that the customer waiting state (predetermined waiting state) has been reached. When this process ends, the special symbol storage check process ends.

  In step S63, the main CPU 66 sets a value (01) for requesting special symbol variation time management to the special symbol control flag, and moves the process to step S64.

  In step S64, a jackpot lottery process is executed. In this process, the main CPU 66 reads out the game state flag, and selects one lottery table from the jackpot lottery table (see FIG. 7) including a plurality of lottery tables having different jackpot lottery values based on the read game state flag. To do. Then, the jackpot lottery is executed from the random number value for the jackpot lottery extracted when the game ball wins the start opening 25 and the selected lottery table (15R probability variable jackpot, 2R probability variable jackpot, 15R normal jackpot or “ Decide one of the "out of the way").

  Here, as shown in the jackpot lottery table of FIG. 7, in the lottery table in the normal mode or the short time mode and the lottery table in the probability variation mode, the jackpot lottery value is 7/400 (15R normal jackpot, 70/400 (the sum of all jackpot lottery values per 15R normal jackpot, 15R probability jackpot and 2R probability jackpot) in the probability variation mode, while it is set to 15R probability jackpot and 2R probability jackpot Is set. That is, by selecting the lottery table based on the gaming state flag, the probability of shifting to the big hit gaming state varies depending on the gaming mode. If this process ends, the process moves to a step S65.

  In step S65, the main CPU 66 determines whether or not it is a big hit. In this process, the main CPU 66 moves the process to step S66 if the lottery result in the jackpot lottery process in step S64 described above is a big win, and moves the process to step S67 if not the big win.

  In step S66, a specific symbol determination process is executed. In this process, the main CPU 66 determines a specific symbol to be displayed corresponding to the jackpot type determined in step S64. For example, for the 15R probability variable jackpot, the specific symbol is determined as “7”, for the 2R probability variable jackpot, the specific symbol is “3”, or for the 15R normal jackpot, the specific symbol is “5”. As such, a specific symbol is determined corresponding to each jackpot. Then, the determined specific symbol is stored in a predetermined area of the main RAM 70. As a result, the special symbol corresponding to the jackpot is derived and displayed on the special symbol display 33. If this process ends, the process moves to a step S68.

  In step S67, a missing symbol determination process is executed. In this process, the main CPU 66 determines a specific symbol (for example, a number other than “7”, “3”, “5”) corresponding to the off symbol and stores it in a predetermined area of the main RAM 70. As a result, a special symbol corresponding to the deviation is derived and displayed on the special symbol display 33. If this process ends, the process moves to a step S68.

  In step S68, a gaming state determination process is performed. In this gaming state determination process, when the main CPU 66 determines that the current gaming state flag is in the probability variation mode or the short time mode, the main CPU 66 proceeds to step S70 and determines that the current gaming state flag is in the normal mode. If it is determined, in step S69, the special symbol variation time in the normal mode (for example, 10 seconds) is set in the special symbol variation timer and stored in a predetermined area of the main RAM 70. Then, the process proceeds to step S71.

  In step S70, the main CPU 66 sets a special symbol variation time in the probability variation mode or the short time mode (a time shorter than the special symbol variation time in the normal mode, for example, 5 seconds) in the special symbol variation timer. Store in the area. Then, the process proceeds to step S71.

  In step S71, the main CPU 66 stores a request for starting the variable display to the special symbol display 33 (see FIG. 4) in a predetermined area of the main RAM 70, and moves the process to step S72. By this processing, the special symbol display 33 displays the variation of the special symbol in accordance with the variation time set in the special symbol variation timer in the steps S69 and S70, and after the predetermined time has elapsed (the special symbol variation). After the timer expires, the special symbol “big hit” or “lost” determined in step S66 and step S67 is stopped and displayed.

In step S72, the decoration pattern displayed in the display area 32a of the liquid crystal display device 32 and the effect time determination process are performed. In this process, the main CPU 66 uses the “big hit” or “out of place” data stored in step S66 or step S67 and the special symbol variation time data stored in step S69 or step S70 as the step of FIG. By the command output process of S25, the main CPU 66 of the main control circuit 60 supplies the sub CPU 206 of the sub control circuit 200 as a derived symbol designation command. Thereby, in the sub control circuit 200, the decorative symbol is derived and displayed on the display area 32a of the liquid crystal display device 32, and the variation time of the decorative symbol is also determined. As a result, the variation time of the special symbol derived and displayed on the special symbol display 33 and the variation time of the decorative symbol derived and displayed on the liquid crystal display device 32 are synchronized.
[Normal symbol control processing]
The subroutine executed in step S13 in FIG. 8 will be described with reference to FIG. As shown in FIG. 12, first, the main CPU 66 loads a normal symbol control flag in step S101. In this process, the main CPU 66 reads the normal symbol control flag. If this process ends, the process moves to a step S102.

  In step S102, the main CPU 66 determines whether or not the normal symbol control flag is a value (00) indicating a normal symbol storage check request. If the normal symbol control flag is not (00), the process proceeds to step S104. . If the normal symbol control flag is (00), the normal symbol storage check process in step 103 is performed. This normal symbol storage check process will be described in detail with reference to FIG. 13, but the main CPU 66 checks the number of reserved normal symbols, and when there is a number of reserved symbols, the main CPU 66 determines whether the normal symbol is hit, starts changing the normal symbol, The normal symbol variation timer is set, etc., and (01) which is the processing request for the next step is set in the normal symbol control flag, and the processing is terminated.

  In step S104, the main CPU 66 determines whether or not the normal symbol control flag is (01). If the normal symbol control flag is not (01), the process proceeds to step S107. If the normal symbol control flag is (01), it is determined in step S105 whether the normal symbol variation timer has timed up (that is, “0”). If the time has not expired, the process ends. . On the other hand, when the normal symbol variation timer expires, the main CPU 66 performs a normal symbol stop process in step S106. In this normal symbol stop process, the main CPU 66 sets a request to stop the fluctuation to the normal symbol display 35 and stores it in a predetermined area of the main RAM 70. As a result, the normal symbol display 35 displays the determination result of “success” or “displacement” of the normal symbol determined in the normal symbol storage check process. When this process is completed, the stored number of normal symbols stored in a predetermined area of the main RAM 70 is updated so as to decrease by “1”. Then, (02) is set in the normal symbol control flag and the process is terminated.

  In step S107, the main CPU 66 determines whether or not the normal symbol control flag is (02). If the normal symbol control flag is not (02), the process proceeds to step S111. If the normal symbol control flag is (02), the process proceeds to step S108 to determine whether or not the normal symbol is a hit. If the main CPU 66 determines that the normal symbol is a winning symbol, the main CPU 66 shifts the processing to the normal electric character releasing process in step S109. On the other hand, when determining that the normal symbol is not a hit, the main CPU 66 sets a value (00) for requesting the normal symbol storage check to the normal symbol control flag and ends the processing in step S110.

  In the ordinary electric accessory release process in step S109, the main CPU 66 performs an opening process of the blade member 23 of the ordinary electric accessory (stores the release of the ordinary electric accessory in a predetermined area of the main RAM 70). Furthermore, the opening time of the blade member 23 of the ordinary electric accessory (for example, 3 seconds when the game state is the probability change mode or the short time mode, 0.2 seconds when the game mode is the normal mode) according to the game state of the game table is normal. The electric accessory release timer is set, the normal symbol control flag is set to (03), and the process ends.

  In step S111, the main CPU 66 determines whether or not the normal symbol control flag is (03). If the normal symbol control flag is not (03), the process proceeds to step S114. If the normal symbol control flag is (03), the process proceeds to step S112 to determine whether the normal electric accessory release timer has timed up (that is, “0”). Then, when the normal electric accessory release timer has not expired, the process is terminated. On the other hand, when it is determined that the normal electric accessory release timer has timed out, in the normal electric accessory closing process of step S113, the blade member 23, which is an ordinary electric accessory, is closed (normally in a predetermined area of the main RAM 70). Memorize the closing of the electric accessory). Then, (04) is set in the normal symbol control flag and the process is terminated.

In step S114, the main CPU 66 clears the normal symbol control flag (that is, sets the value “00” for requesting the normal symbol storage check) and ends the process.
[Normal symbol memory check processing]
The subroutine executed in step S103 in FIG. 12 will be described with reference to FIG.

  First, in step S121, the main CPU 66 determines whether or not the normal symbol holding number is “0”. If it is determined that the normal symbol holding number is “0”, the normal symbol storage check is performed. The process ends. This normal symbol holding number is stored in a predetermined area of the main RAM 70. When it is detected that a game ball has passed through the passing gate 54, the normal symbol holding number increases by "1" with the predetermined number (for example, "4") as an upper limit. When the variable display of the normal symbol in the normal symbol game is completed, “1” is subtracted and the memory is updated. On the other hand, if the main CPU 66 determines that the number of retained normal symbols is not “0”, in step S122, the main CPU 66 sets the value “01” of the normal symbol variation timer monitoring request to the normal symbol control flag, and then proceeds to step S123. Move processing.

  In step S123, a normal symbol hit determination process is executed. In this processing, the main CPU 66 determines the normal symbol per-determining random number extracted when the normal symbol starting area is passed (by passing the game ball through the passing gate 54) and the normal symbol per-unit determination stored in the main ROM 68. Refers to the value. Then, as a result of the reference, when the random value for determination per ordinary symbol matches the determination value per ordinary symbol as a result of the reference, the main CPU 66 stores data indicating the winning symbol (for example, “◯” symbol) in a predetermined area of the main RAM 70. To remember. On the other hand, as a result of the reference, if the random value for determination per normal symbol does not match the determination value per normal symbol as a result of the reference, the main CPU 66 stores data indicating an off symbol (for example, “×” symbol) in a predetermined area of the main RAM 70. To remember. The winning symbol and the off symbol stored in this manner are supplied to the normal symbol display 35 as a derived normal symbol designation command. As a result, the normal symbol display 35 starts normal symbol variation display (for example, “◯” and “x” symbols are alternately blinked). Thereafter, the process proceeds to step S124.

  In step S124, the main CPU 66 determines whether or not the game state flag is in the probability change mode or the time reduction mode. If the game state flag is in the probability change mode or the time reduction mode, in step S126, the main CPU 66 The normal symbol variation stop time (for example, 5 seconds) shorter than that in the normal mode is set in the normal symbol variation timer, and the processing is terminated. On the other hand, if the gaming state is not the probability variation mode or the time reduction mode (that is, the normal mode), in step S125, the main CPU 66 sets the normal symbol variation stop time (for example, 30 seconds) longer than the probability variation mode or the time reduction mode to the normal symbol variation timer. Set to ending.

  Here, the gaming state flag of the pachinko gaming machine 10 in the present embodiment will be described. As described above, any one of the normal mode, the probability variation mode, and the time reduction mode is set in the gaming state flag in the pachinko gaming machine 10. Here, as shown in the jackpot lottery table in FIG. 6, when the game state flag is in the probability variation mode, the lottery value is 70/400 (15R normal jackpot, 2R probability jackpot, all 15R probability variation jackpot values). In contrast, when the game state flag is in the normal mode or the short-time mode, the numerical value for drawing the jackpot is 7/400 (15R normal jackpot, 2R probability variable jackpot, 15R probability variable jackpot all numbers) Total)). In other words, when the gaming state flag is in the probability variation mode, it is possible to expect winning of the jackpot gaming state with a 10 times higher probability than in the normal mode or the short time mode. In other words, the probability variation mode can be said to be a very advantageous game mode with a large expected value for the next jackpot for the player.

Furthermore, also in the variation time of the special symbol and the normal symbol, as described above, when the gaming state flag is in the probability variation mode or the time reduction mode and in the normal mode, the gaming state flag is in the probability variation mode or the time reduction mode, The variation time of special symbols and normal symbols is set short. Further, since the opening time of the blade member 23 attached to the start port 25 when the normal state is hit is set longer than the normal mode when the game state flag is in the probability variation mode or the time reduction mode, the blade member 23 As a result, the opportunity for a game ball to win the start opening 25 increases. In other words, when the game state flag is in the probability variation mode and the short time mode, the number of special symbol lotteries per unit time increases compared to the normal mode, which is also an advantageous state for the player.
[Sub control circuit main processing]
On the other hand, the sub-control circuit 200 executes the sub-control circuit main process. The sub control circuit main process will be described with reference to FIG. The sub-control circuit main process is a process that starts when the power is turned on.

  First, in step S201, the sub CPU 206 executes initial setting processing such as RAM access permission and work area initialization. That is, the sub CPU 206 performs a predetermined initial setting for normally playing the game based on the power being turned on. In the present embodiment, the sub CPU 206 that executes step S201 corresponds to an example of an initial setting unit. If this process ends, the process moves to a step S202.

  In step S202, the sub CPU 206 executes random number update processing. In this process, the sub CPU 206 updates various random number values positioned in a predetermined area of the work RAM 210. If this process ends, the process moves to a step S203.

  In step S203, the sub CPU 206 executes command analysis processing. In this process, the sub CPU 206 analyzes a command sent from the main CPU 66 of the main control circuit 60 and executes a process according to the analyzed command. If this process ends, the process moves to a step S204.

  In step S204, the sub CPU 206 executes display control processing. In this process, when the sub CPU 206 receives a derived symbol designation command from the main CPU 66 of the main control circuit 60 in the command analysis process, the sub CPU 206 performs image display control such as a decorative symbol according to the derived symbol designation command. This is performed in the display area 32 a of the liquid crystal display device 32.

  Then, the sub CPU 206 executes a sound control process for controlling sound generated from the speaker 46 (step S205) and a lamp control process for controlling light emission of the various lamps 133a and 133b (step S206). If this process ends, the process moves to a step S202.

Thus, in the sub-control circuit main process, after the initial setting process in step S201 is completed, the processes from step S202 to step S206 are repeatedly executed.
[Pressure judgment notification process]
FIG. 15 is a flowchart of the pressure determination notification process (step S14) executed in the main process of FIG. Hereinafter, the pressure determination notification processing according to the present invention will be described with reference to FIG.

  First, in step S301, the main CPU 66 uses the current determination data of the game board 14 detected by the pressure sensors 27a, 27b, 28a and 28b as game information in the pachinko gaming machine 10 as the pressure determination circuit 65 (FIG. 6). Read out) and store it in a predetermined area of the main RAM 70. In the present embodiment, the pressure sensors 27a, 27b, 28a, 28b for detecting the movement data of the game board 14 are installed on the top, bottom, left and right of the game board 14 (see FIGS. 2 and 3). The movement data of the game board 14 is also acquired as four movement data of the game board 14 up and down and left and right. When this process ends, the process moves to a step S302.

  Next, in step S302, the main CPU 66 determines whether it is already informing that an abnormality has been detected in the motion data of the game board 14, and if it is informing, the process ends. On the other hand, if it is determined that notification is not being performed, the process proceeds to step S303.

  In step S303, the main CPU 66 compares the current motion data of the game board 14 acquired in step S301 with the normal motion data (see FIG. 16) of the game board 14 stored in advance in the main ROM 68. . In the present embodiment, the normal motion data of the game board 14 stored in advance in the main ROM 68 corresponds to 4 corresponding to the pressure sensors 27a, 27b, 28a, 28b installed on the top, bottom, left and right of the game board 14, respectively. The type of normal motion data is stored. Then, the main CPU 66 compares and determines the acquired current motion data of the game board 14 and the corresponding normal motion data, determines the presence or absence of abnormality, and moves the process to step S304.

  Here, in the motion data determination process for the game board 14 in step S303, a change in the motion data on the lower side of the game board 14, for example, a plurality of game balls stay in the game board 14 in the game. Therefore, it is expected that fluctuations in motion data on the lower side of the game board 14 are detected. For example, the number of game balls staying on the game board 14 based on the firing speed of the game balls launched on the game board 14 and the average time taken for the game balls to naturally fall from the top to the bottom on the game board 14. Is calculated, the stay of about 5 to 6 game balls is calculated. Since the weight of one game ball is about 6 grams, motion data of about 30 to 40 grams is changed on the game board 14 during the game. Furthermore, since the falling speed is added to the game ball, the change of the motion data instantaneously applied to the game board 14 is expected to be about 40 grams or more. That is, since the change in the motion data of the game board 14 during the game changes considerably depending on the game state, the normal motion data as a reference for comparison is set in advance as normal storage data corresponding thereto. However, even if a game is in progress, there can be no situation in which hundreds of grams of motion data changes on the game board 14. For example, when a change in motion data of 100 grams or more is detected, the game board 14 It is assumed that a malfunction or some sort of fraud has occurred, and the game board 14 will be notified of an abnormality.

  In step S304, the main CPU 66 determines whether or not an abnormality is detected in the current movement data of the game board 14 in the up, down, left, and right directions. If no abnormality is detected, the main CPU 66 ends the process. On the other hand, if an abnormality is detected, the main CPU 66 stores the movement abnormality detection of the game board 14 in a predetermined area of the main RAM 70 in step S305 and ends the process.

  It should be noted that an abnormality in the motion data of the game board 14 detected in this subroutine and stored in a predetermined area of the main RAM 70 is detected in the command output process in step S25 of the system timer interrupt process (see FIG. 9). By being sent as a gaming state notification command from the main control circuit 60 to the sub-control circuit 200, after being analyzed in the command analysis process in step S203 of the sub-control circuit main process (see FIG. 14), the display control process in step S204 It will be displayed on the liquid crystal display device 32 as an abnormality notification image. Moreover, you may perform the alerting | reporting by the audio | voice from the speakers 46L and 46R and the alerting | reporting by the light emission by the decoration lamps 133a and 133b as needed (refer FIG. 17).
