Further, according to the disclosed embodiment, the opening / closing suppression piece 630 (opening / closing suppression member) is provided at the left side position of the opening / closing door 601, that is, in the vicinity of the left side plate portion 606 l in the game privilege granting apparatus.

  The open / close door 601 shown in FIGS. 5 and 6 is in an open state (first state) in which a player can enter the big winning device entrance 603 of the big winning device 60. The open / close door 601 shown in FIGS. The closed state (second state) in which it is difficult or impossible to enter the big winning device entrance 603 of the big winning device 60. The opening / closing suppression piece 630 (opening / closing suppression member) rotates about the opening / closing suppression piece shaft portion 631 as a central axis. The rotation of the opening / closing restraining piece 630 is unlocked that enables the opening / closing door 601 to change from the second state to the first state when the opening condition of the opening / closing door 601 associated with the big hit game (special game) transition is established. It is performed between the position (see FIG. 6) and the lock position (see FIG. 11) that prevents the opening / closing door 601 from changing from the second state to the first state.

  Specifically, as understood from the enlarged front view of FIG. 6, when the open / close door 601 is in the first state, the game ball P flowing down on the game area 6 contacts the receiving surface 602 of the open / close door 601 and wins a big prize. It is guided into the device entrance 603 and passes through a winning ball count switch (count sensor) 604. On the other hand, the game ball P flowing down the game area 6 collides with the open / close restraining piece 630 in the unlocked position, and is directed to the open / close door 601 (big winning device entrance 603). In other words, the presence / absence of the opening / closing suppression piece 630 causes difficulty in entering the big winning device entrance 603, and the fun of selecting the flow path of the game ball increases.

  The positional relationship between the open / close door 601 and the large winning device opening solenoid 620 can be shown as shown in the left side view of the main part in FIG. In the large winning device 60 of the embodiment, a large winning device opening solenoid 620 is provided as an operating member in order to open and close the opening / closing door 601. The plunger 621 inserted through the large winning device opening solenoid 620 retreats against the biasing spring 623 simultaneously with energization (excitation) of the solenoid 620, and a plunger plate formed at the end portion of the plunger 621. The body 622 is also retracted simultaneously. Since the opening / closing door movable member 640 is provided with rod-like plunger clamping protrusions 644 and 644 (see FIGS. 5 and 8), the plunger clamping protrusions 644 and 644 are also attracted to the plunger plate 622 of the plunger 621. fall back. Then, the open / close door movable member 640 rotates with the movable member shaft portion 641 as a rotation axis. In the figure, reference numeral 645 denotes a movable protrusion.

  As can also be seen from FIG. 7, the left side plate portion 606 l is integrated with the opening / closing door upper arm portion 613, and the opening / closing door lower arm portion 614 is provided below the opening / closing door upper arm portion 613. ing. As the opening / closing door movable member 640 is turned upward, the movable rod portion 642 is also lifted (raised). As a result, the open / close door 601 opens as shown in the drawing using the open / close door shaft 611 on the one end side 608 of the opening edge 609 as a rotation axis by the dead weights of the left and right weight portions 616l and 616r (that is, the first state). ). At this time, when the opening / closing door 601 opens to the maximum amount, the distal end portion of the opening / closing door lower arm 614 and the movable rod engaging portion 643 are engaged. In the drawing, reference numeral 617 denotes an upper arm engaging surface of the upper arm portion of the opening / closing door, and 618 denotes an engaging surface of the lower arm portion of the lower arm portion of the opening / closing door.

  Next, the position and operation of the opening / closing suppression piece 630 will be described with reference to FIGS. The opening / closing suppression piece 630 is connected to the interlocking member 650 via an opening / closing suppression piece shaft portion 631 that penetrates the mounting base 605. The interlocking member 650 has a substantially d-shape (a shape similar to d) when viewed from the rear of the prize winning device 60 (see FIG. 8). The pivoting movement of the open / close door movable member 640 accompanying the operation of the large winning device opening solenoid 620 is as described above. In this case, according to the movement of the movable rod portion 642, the movable protrusion piece 645 located at the tip thereof is also lifted (raised). Therefore, the passive contact portion 651 of the interlocking member 650 is pushed up upon receiving the contact of the movable protrusion piece 645. As a result, the interlocking member 650 is rotated about the opening / closing suppression piece shaft portion 631 as a rotation axis, and the opening / closing suppression piece 630 is also rotated upward. In this way, the open / close suppression piece 630 can be shifted to the unlocked position (see FIGS. 5 and 6). That is, the open / close door 601 does not receive the resistance of the open / close suppression piece 630. The sign arrows d11, d12, d13, d14, d15, d16, d17 in FIG. 9 indicate the direction of operation in each part.

  Next, as can be understood from the perspective view of FIG. 10 and the front view of FIG. 11, the open / close door 601 of the big prize device 60 is difficult to enter the game ball into the big prize device entrance 603. It is in the second state where it is impossible to sphere. As shown in FIG. 11, the game ball P flowing down the game area flows down the front portion 612 of the open / close door 601 as it is. Moreover, the opening / closing suppression piece 630 has shifted to the lock position that prevents the opening / closing door 601 from being changed from the second state to the first state. As can be seen from the drawing, the blocking portion 632 of the opening / closing suppression piece 630 is in contact with the left weight portion 616 l of the opening / closing door 601. Therefore, the opening / closing restraining piece 630 acts as a restraint and prevents the opening / closing of the opening / closing door 601 (variable to the first state).

  The positional relationship between the opening / closing door 601 and the special winning device opening solenoid 620 in the second state can be shown as the left side view of the main part of FIG. When the plunger 621 inserted through the large winning device opening solenoid 620 is de-energized (excited), the plunger 621 and the plunger plate 622 formed at the end thereof are also urged by the urging force of the urging spring 623. Move forward at the same time. As the plunger 621 advances, the plunger plate 622 presses the plunger clamping protrusions 644 and 644 (see FIGS. 5 and 8) of the open / close door movable member 640. Then, the open / close door movable member 640 rotates in the direction opposite to the case of FIG. 7 using the movable member shaft portion 641 as a rotation axis.

  As the opening / closing door movable member 640 is rotated downward, the movable rod portion 642 is also lowered (lowered). Therefore, as shown in FIG. 12, the movable rod engaging portion 643 at the tip of the movable rod portion 642 contacts the lower arm engaging surface 618 of the opening / closing door lower arm 614. Using this contact, the opening / closing door 601 is closed as shown in the figure using the opening / closing door shaft 611 on one end side 608 of the opening edge 609 as a rotation axis (becomes the second state).

  The position and operation of the opening / closing suppression piece 630 when the opening / closing door shaft 611 is in the second state will be described with reference to FIG. The pivoting movement of the open / close door movable member 640 accompanying the operation of the large winning device opening solenoid 620 is as described in FIG. In this case, according to the movement of the movable rod portion 642, the movable protrusion piece 645 located at the tip of the movable rod portion 642 is also lowered (lowered). Therefore, the passive contact portion 651 of the interlocking member 650 is lowered together by the lowering due to the rotation of the movable protrusion piece 645. As a result, the interlocking member 650 is rotated about the opening / closing suppression piece shaft portion 631 as the rotation axis, and the opening / closing suppression piece 630 is also rotated downward. In this way, the opening / closing suppression piece 630 can be shifted to the locked position (see FIGS. 10 and 11). That is, the open / close door 601 receives the resistance of the open / close suppression piece 630 (blocking portion 632). The sign arrows d21, d22, d23, d24, d25, d26, and d27 in FIG.

  In the first prize winning device (game privilege granting apparatus) of the first embodiment, the opening / closing suppression piece changes in conjunction with the operation of the first prize winning device opening solenoid, so that the open / close door of the first prize winning device is in the original closed state ( An unnatural opening when in the second state) can be prevented, and an unauthorized opening or the like with respect to the big winning device can be suppressed. In addition, depending on the position state of the opening / closing restraining piece, a difference occurs in the ease of entering into the big winning device entrance, and the fun of the game increases.

  The big prize device 60A disclosed in FIGS. 14 to 22 is a second embodiment, and includes two solenoids, a big prize device opening solenoid 620 and an opening / closing restraining piece solenoid 625 as operating members. Portions common to the above-described big winning device 60 of the first embodiment are denoted by the same reference numerals and description thereof is omitted. As can be understood from the perspective view of FIG. 14 and the front view of FIG. 15, the open / close door 601 is in a first state in which it is possible to enter the big winning device entrance 603 of the big winning device 60A. The variable opening / closing door 601 is common to the case of the big prize device 60 of the first embodiment. Reference numeral 626 denotes a plunger of an opening / closing restraining piece solenoid, 627 denotes a plunger plate, 631a denotes an opening / closing restraining piece shaft portion, 635 denotes a hard guide surface, 660 denotes a transmission rod, and 662 denotes a holding ring.

  The open / close restraining piece 630A provided in the grand prize winning device 60A is in a position where the easy guide surface 634 faces the game area 6 above. The position of the opening / closing restraining piece 630A indicates that the opening / closing door 601 changes from the second state (see FIG. 19 and the like) to the first state when the opening condition of the opening / closing door 601 associated with the big hit game (special game) transition is established. It hits the unlocked position that is possible. At the same time, as shown in FIG. 15, the game ball P flowing down the game area 6 comes into contact with the easy guide surface 634 of the open / close restraining piece 630A, and the receiving surface 602 of the open / close door 601 (that is, the big prize winning device entrance 603). A first guiding state that can be guided to the position is also formed. That is, when the opening / closing restraining piece 630A is in the first guiding state, the receiving surface of the opening / closing door is substantially expanded, and more game balls can be received by the grand prize winning device (game privilege granting device). ) That is, high induction efficiency into the special winning device can be obtained.

  As shown in the perspective view of FIG. 16, the open / close suppression piece 630A provided in the big prize device 60A has a substantially wedge shape (or teardrop shape) when viewed from the front, and an easy guide surface 634 and a hard guide surface 635 are formed. The The change between the first state and the second state of the opening / closing suppression piece 630A is rotation about the opening / closing suppression piece shaft portion 631a. Reference numeral 633 denotes a passive pin.

  The position and operation of the opening / closing suppression piece 630A will be described with reference to FIGS. The drive of the solenoid 625 for opening / closing suppression piece is transmitted to the opening / closing suppression piece 630A via the transmission rod 660. A sandwiching ring 662 that receives a biasing force of a biasing spring 628 is interposed between the plunger plate 627 and the plunger 626 of the solenoid 625 for opening / closing suppression piece. The transmission rod 660 is substantially L-shaped, and two rod-like plunger passive protrusions 664 and 664 are provided at one end.

  The plunger 626 retreats against the urging spring 628 simultaneously with energization (excitation) to the solenoid 625 for opening / closing suppression piece, and the plunger plate 622 formed at the end portion of the plunger 626 also retreats simultaneously. Since the plunger plate 627 (clamping ring 662) is clamped by the two plunger passive protrusions 664 and 664, the retreating operation of the open / close suppression piece solenoid 625 is accurately transmitted to the transmission rod 660. Then, the transmission rod 660 rotates about the rod shaft portion 661 as a rotation axis, and the substantially U-shaped rod engaging portion 663 is lifted (raised) in conjunction with this movement. The passive pin 633 protruding from the open / close restraining piece 630A is gently engaged with the rod engaging portions 663 and 663 (see FIG. 17). Of course, the passive pin 633 also rises in accordance with the rotation of the transmission rod 660. As a result, the opening / closing suppression piece 630A is rotated with the opening / closing suppression piece shaft portion 631a as the center of rotation, and the easy guide surface 634 is directed upward as shown in FIG. The opening / closing suppression piece 630A is in the unlocked position and in the first guiding state. The sign arrows d31, d32, d33, d34, d35, d36 in FIG. 18 indicate the direction of operation in each part.

  Next, as can be seen from the perspective view of FIG. 19 and the front view of FIG. 20, the open / close door 601 of the big prize device 60A is difficult to enter the game ball into the big prize device entrance 603. It is in the second state where it is impossible to sphere. As shown in FIG. 20, the game ball P flowing down the game area flows down the front part 612 of the open / close door 601 as it is. In addition, the opening / closing suppression piece 630A has shifted to the lock position that prevents the opening / closing door 601 from being changed from the second state to the first state. As can be seen from the drawing, the blocking portion 632 of the opening / closing suppression piece 630A is in contact with the left weight portion 616l of the opening / closing door 601. Therefore, the opening / closing restraining piece 630A is restrained and prevents the opening / closing of the opening / closing door 601 (variable to the first state). In addition, as shown in FIG. 20, the open / close restraining piece 630 </ b> A in the illustrated lock position is in a position with its hard guide surface 635 facing upward. Accordingly, the game ball P flowing down the game area 6 abuts on the hard guidance surface 635, and a second guidance state is formed in which guidance to the big winning device 60A (large winning device entrance 603) is impossible. That is, when the opening / closing suppression piece 630A is in the second induction state, the induction into the big winning device is inhibited.

  Further, a mode in which the opening / closing suppression piece 630A is changed from the first guidance state to the second guidance state (lock position) will be described with reference to FIGS. When energization (excitation) to the solenoid 625 for opening / closing suppression piece is lost, the plunger 626 and the plunger plate body 627 (holding ring 662) formed at the end portion thereof advance simultaneously by the urging force of the urging spring 628. Thus, the plunger passive protrusions 664 and 664 of the transmission rod 660 are pressed and rotate around the rod shaft portion 661 as a rotation axis. In conjunction with this movement, the substantially U-shaped rod engaging portions 663 and 663 are also pushed down (lowered). Contrary to the case of FIGS. 17 and 18, the passive pin 633 also descends in accordance with the rotation of the transmission rod 660. As a result, the opening / closing suppression piece 630A rotates about the opening / closing suppression piece shaft portion 631a, and the hard-to-guide surface 635 faces upward as shown in FIG. The sign arrows d41, d42, d43, d44, and d45 in FIG.

  Even in the big winning device (game privilege granting device) of the second embodiment, similarly, it is possible to prevent an unnatural opening when the open / close door of the big winning device is in the original closed state (second state). . In addition, since the opening / closing suppression piece is variable independently of the operation of the large winning device opening solenoid, even in the open state (first state) of the open / close door, depending on the position state of the opening / closing suppression piece, Differences in the ease of entering the ball, making the game more interesting.

  FIG. 23 and FIG. 24 disclose the main configuration of the big winning device of the third embodiment. According to this embodiment, the operation member has one solenoid (large winning device opening solenoid 620), and includes a stepping motor 670 instead of the open / close suppression piece solenoid 625 of the large winning device 60A of the second embodiment. The opening / closing suppression piece 630 </ b> B is connected to the stepping motor 670 by the motor shaft 671 and is subjected to rotation and angle control of the motor 670. In FIG. 23, the opening / closing suppression piece 630B is in the first guiding state with the easy guide surface 634 facing upward, and in FIG. 24, the opening / closing suppression piece 630B is in the second guiding state with the difficult guiding surface 635 facing upward.

  In the case of the opening / closing suppression piece 630B in the large winning device 60A of the second embodiment, the variable operation of the opening / closing suppression piece 630B itself tends to be monotonous because the solenoid for the opening / closing suppression piece is driven. However, although not particularly illustrated, it is possible to form an induction state between the first induction state and the second induction state, for example, by the angle control function of the stepping motor. With regard to entering a game ball into the big winning device entrance using the opening / closing restraining piece, it is possible to set the level of the game ball guiding efficiency such as ease and difficulty in detail. For this reason, depending on the position state of the opening / closing restraining piece, the ease of entering the big winning device entrance is changed, and the fun of the game is further increased. In each of the detailed examples, the first guiding state is a state in which the guiding efficiency of the game ball to the prize winning device entrance is higher than that in the second guiding state.

  Subsequently, a control system in the main control circuit 121 of the ball game machine 1 will be described. The main counters of the CPU of the main control circuit 121 shown in FIG. 4 include counters such as a jackpot determination random number counter, a jackpot symbol random number counter, a reach random number counter, a special symbol data random number counter, and an effect random number counter. is there. Up to four numerical values acquired at predetermined times of each counter are stored in the RAM of the main control circuit 121. The numerical value of each counter stored in the RAM is cleared after a series of game operation processes based on the counter. The operation of each counter is shown below.

  The jackpot determination random number counter is a random number counter for determining whether or not the game is a big hit and miss, and has a random number range of 0 to 314. This counter is equivalent to the success / failure determination means in the ball game machine 1 and is a counter for lottery determination based on the detection of the game ball. This starts from “0” when the gaming machine 1 is powered on, and is incremented by 1 for each main random number update process described later. When the numerical value reaches “314”, it returns to “0” again and repeats the addition. The numerical value of the counter is acquired when the game ball wins (enters) the starting winning opening 10 and is detected by the starting winning opening detecting switch, and is a jackpot value determined in advance, which is a normal symbol combination in this embodiment. It is contrasted with '7' during normal time (low probability state) and '7', '57', '107', '157' when the probability variation state (high probability state) is a probability variable symbol combination. , '207', '257', and '307', it is determined whether or not it is a big hit.

  In addition, since the game ball may win (enter a ball) at the start winning opening 10 and the counter value may be acquired again until the determination of whether or not is completed, the stored value of the counter (updated acquisition value) ) Is temporarily stored in the RAM of the main control circuit 121 for each of the starting winning openings 10 without including the acquired value currently being determined, and is used for sequential determination.

  The jackpot symbol random number counter is a counter that determines a special symbol combination for deterministic stoppage jackpot that is confirmed and stopped on the image display unit 50 when the above-described determination result is successful, and the random number range is 0 to 11. This counter starts from “0” when the power of the ball game machine 1 is turned on, and is incremented by 1 for each main random number update process described later. When the numerical value reaches “11”, it returns to “0” again and is incremented. repeat. The value of the counter is acquired when a game ball wins (enters) the start winning opening 10 and is detected by the start winning opening detecting switch, and does not include the symbol for the variable display and the start winning opening 10 A maximum of four for each ball is stored in the special symbol random number storage area of the RAM of the main control circuit 121. The jackpot symbol random number counter is assigned a predetermined jackpot stop symbol combination corresponding to each number in advance. In the embodiment, when the obtained numerical value of the counter is “0”, the left, middle, and right special symbols are “0, 0, 0” in order, and similarly when the value is “1, 1, 1”. , '2, 2, 2' for '2', '3, 3, 3' for '3', '4, 4, 4' for '4', '5' for '5' “5, 5, 5”, “6”, “6, 6, 6”, “7”, “7, 7, 7”, “8”, “8, 8, 8”, “ “9,9,9” for 9 ”,“ 10,10,10 ”for“ 10 ”,“ 11,11,11 ”for“ 11 ”(all special symbols are the same) Is finally displayed as a confirmed stoppage as a confirmed jackpot stop symbol combination.

  In the present embodiment, the jackpot symbol random number counter is determined by the obtained numerical value, in addition to setting a bonus special symbol, whether or not the probability variation state is set, etc. The game produced by the gaming machine acts as a game control means in the main control circuit 121. Further, in the case of the third embodiment, it is also used for controlling the guidance state of the opening / closing suppression piece 630B.

  The reach random number counter is a counter that determines whether or not the reach state is reached when the jackpot determination result by the jackpot determination random number is out of reach, and the random number range is 0 to 126. This counter starts from ‘0’ when the gaming machine 1 is powered on, and is incremented by 1 for each main random number update process described later. When the value reaches ‘126’, it returns to ‘0’ again and repeats the addition. The value of the counter is acquired when the game ball wins (enters) the start winning opening 10 and is detected by the start winning opening detection switch. If the result of the determination is wrong, the numerical value is determined in advance. Whether or not the reach state is established is determined by comparing with the reach establishment value.

  In this embodiment, the reach establishment values are “5”, “17”, “28”, “40”, “51”, “63”, “74”, “86”, “97”, “109”, When the obtained value of the reach random number counter becomes “120”, the reach state is established. A predetermined number of numerical values acquired by the reach random number counter is stored in the RAM of the main control circuit 121, and in this example, a maximum of four numerical values are stored for each of the starting winning holes 10 without including the numerical value being determined. In the embodiment, when the jackpot winning determination result by the jackpot determination random number counter is a jackpot, the reach state is always established, and therefore the reach random number counter is not used.

  The special symbol data random number counter is used to determine a special symbol combination for losing the symbol to be confirmed and stopped on the image display unit 50 when the result of the big hit / failure determination result by the jackpot determination random number counter is lost. This special symbol data random number counter includes a random number counter for special symbol data 1 for determining the left special symbol to be confirmed and stopped displayed on the image display unit 50, a random number counter for special symbol data 2 for determining the middle special symbol, It is composed of a counter for random numbers of special symbol data 3 for determining the right special symbol, and any special symbol data random number counter has a random number range: 0 to 11.

  The random number counter of the special symbol data 1 starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each main random number update process described later. When the numerical value becomes “11”, it is set to “0” again. Return and repeat addition. The random number counter for special symbol data 2 starts from “0” when the gaming machine 1 is turned on, and is incremented by one when the random number counter for special symbol data 1 is updated to “0”. When it reaches 11, it returns to “0” again and repeats addition. The random number counter of special symbol data 3 starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 when the random number counter of special symbol data 2 is updated to “0”. When it reaches 11, it returns to “0” again and repeats addition. The number acquired by each counter is stored in a predetermined number in the RAM of the main control circuit 121. In this example, up to four numbers are stored for each ball of the start winning opening 10 without including the numerical value being determined. For this reason, even if each random number range of the random number counter of each special symbol data is the same, it is possible to avoid that each counter is synchronized (added in the same combination).

  A symbol corresponding to each numerical value is assigned in advance to the numerical value of the random number counter of each special symbol data. In the embodiment, for each acquired numerical value of each counter, “0” when the acquired numerical value is “0”, “1” when “1”, “2” when “2”, “3” “3” for “4”, “4” for “4”, “5” for “5”, “6” for “6”, “7” for “7”, “8” A special symbol “8” is assigned for “9”, “9” for “9”, “10” for “10”, and “11” for “11”. In this way, the left special symbol, middle special symbol, and right special symbol combination to be confirmed and stopped on the image display unit 50 at the time of detachment is determined.

  The effect random number counter is a counter for selecting a variation pattern of special symbol variation from the first table pattern in Table 1 and the second table pattern in Table 2, and the random number range is 0 to 198. The effect random number counter starts from “0” when the gaming machine 1 is turned on, and is incremented by 1 for each main random number update process described later. When the numerical value becomes “198”, it returns to “0” again and increments. repeat. The number obtained for the effect random number counter is stored in the RAM of the main control circuit 121 in a predetermined number, and in the embodiment, up to four numbers are stored for each of the starting winning holes 10 without including the numerical value being determined. If the jackpot winning / not determining result by the jackpot winning random number is winning, the variation patterns 11, 12, and 13 of the first table pattern are used. If the same winning / failing determination result is out of the range, if the reach is determined from the second table pattern, the variation occurs. Patterns 21, 22, and 23 are used, and if there is no reach, variation patterns 24, 25, and 26 are used. According to this example, the production variation time is also selected.

  Flags provided in the main control circuit 121 include a jackpot flag, a jackpot end flag, a start winning slot prize flag, a special game running flag, a probability change (probability change) flag, a reach flag, a time reduction flag, and a normal symbol (small hit) Various flags, such as a flag, are mentioned. These flags are all set to OFF at the time of initial setting.

  Processing executed by the main control circuit 121 of the gaming machine 1 according to the embodiment will be described with reference to the following flowchart. The CPU of the main control circuit 121 executes the main process M according to various programs stored in the ROM of the same circuit. In the main process M, as understood from the flowchart of FIG. 25, initial setting (S1), interrupt prohibition process (S2), main random number update process (S3), interrupt permission process (S4), interrupt process (S10). Is done.

  In the initial setting (S1), stack setting, constant setting, CPU setting, interrupt time setting, SIO, PIO, CTC setting and the like are performed. The main process M is repeatedly performed at every interruption time, but the initial setting (S1) is required only when the power is turned on, so only the first order is executed, and not thereafter. In the interrupt prohibition process (S2), in the case of the embodiment, even if the interrupt process (S10) is entered every 4 msec, the interrupt is prohibited until a predetermined interrupt permission condition is satisfied. In the main random number update process (S3), the random number value of each counter is incremented and updated by 1 every time the update process (S3) is performed, and returns to '0' when reaching the upper limit value of the corresponding random number, The addition starts again. Each updated random number is stored in the RAM of the main control circuit 121. In the interrupt permission process (S4), permission is given to the interrupt process (S10) that enters every 4 msec.

  In the interruption process (S10), as can be understood from the flowchart of FIG. 26, the output process (S100), the input process (S200), the main random number update process (S300), the start winning a prize opening switch detection process (S400), the normal Operation processing (S500), special operation processing (S1000), reserved ball number processing (S1500), and other processing (S1600) are performed.

  In the output process (S100), the presence or absence of output data is confirmed in the RAM command buffer of the main control circuit 121 by each process. If there is output data, the output data in the output buffer is sent to each control circuit. Is output. If there is no output data, no data is output and the process ends. The output data includes commands for various game states such as a special game state, a bonus game state, and a probability variation state.

  In the input process (S200), signal input is performed when there are detection signals from various sensors (detection switches) provided in the ball game machine 1.

  In the main random number update process (S300), the same process as the main random number update process (S3) performed in the main process M is performed.

  In the start winning opening switch detection process (S400), as understood from the flowchart of FIG. 27, whether the game ball has won the start winning opening 10, that is, the game ball has entered the start winning opening 10 is the start winning prize. It is confirmed whether or not it has been detected by the mouth detection switch (S401). If there is no confirmation of winning at the start winning opening, the start winning end switch detection process (S400) ends. When there is a winning game ball at the start winning opening, it is confirmed whether or not the number of reserved balls for special symbols stored in the RAM (corresponding to the detected number storage means) of the main control circuit 121 is 4 or more. (S402). Here, when the number of reserved balls is four or more, since the set limit of the number of reserved balls is exceeded, the start winning a prize opening switch detection process (S400) ends.

  When the number of reserved balls is not 4 or more (less than 4), the number of game balls detected by the start winning port detection switch is added to the number of reserved balls for the special symbol (S403). Subsequently, a random number value related to a special symbol stored in the RAM of the main control circuit 121 is acquired, and the acquired random number is saved (stored) in a RAM address corresponding to the current number of reserved balls ( S404). The random numbers acquired in S404 are jackpot winning / no-go determining random numbers, jackpot symbol random numbers, reach random numbers, special symbol data random numbers, production random numbers, and the like. The acquired random number is saved in the RAM address corresponding to the current number of reserved balls. For example, when the current number of reserved balls is 1, the random number value is saved in the RAM address corresponding to the number of reserved balls 1 It is saved in the same manner according to the number of reserved balls.

  In the normal operation process (S500), whether or not the normal symbol is determined and random numbers related to the symbol setting are acquired, the normal symbol per unit (small hit) is determined, the normal symbol fluctuates or stops, and the start winning opening 10 is opened and closed. The process related to the normal symbol is performed. In the description of the present invention, the details of the normal symbol processing are omitted.

  In the special operation process (S1000), as understood from the flowchart of FIG. 28, a special symbol creation process (S1010) is performed to determine whether the special operation status is 1 (S1020) or whether the special operation status is 2. No (S1030), it is confirmed whether the special operation status is 3 (S1030). When the special operation status corresponds to each predetermined value, the process proceeds to a special symbol standby process (S1100), a special symbol change process (S1200), and a special symbol confirmation process (S1300). When the special operation status does not correspond to any one of 1, 2, and 3, that is, when the special operation status is 4, special electric accessory processing (S1400) is performed.

  In the off-special symbol creation process (S1010), as can be understood from the flowchart of FIG. 29, the address value of the special symbol data 1 acquired in the start winning opening switch detection process (S400) and stored in the RAM. Is set as the storage source address value (S1011), and the special symbol data 3 acquired in the start winning a prize opening switch detection process (S400) and stored in the RAM is loaded (read out) as a determination value (S1012). Next, it is confirmed whether or not the random number of the special symbol data 3 as the determination value and the random number of the special symbol data 1 stored in the storage source address value match each other (S1013). If the two random numbers match, the off special symbol creation process (S1010) ends, and the off special symbol data is not updated. If the two random numbers do not match, the data storage destination address value of the special symbol for outage in the RAM of the main control circuit 121 and the address value of the special symbol data 1, 2, 3 transferred as the special symbol for outage are set ( S1014). Random values of special symbol data 1, 2, and 3 are transferred to the special symbol data storage destination and stored as out-of-band special symbols 1 (left special symbol), 2 (middle special symbol), and 3 (right special symbol) ( S1015), the process (S1010) ends. The special symbols 1, 2, and 3 are off special symbols that are confirmed and stopped on the image display unit 50.

  In the special symbol standby process (S1100) when the special action status is 1 in S1020, as understood from the flowchart of FIG. 30, the presence / absence of the number of reserved balls is confirmed (S1101), and the number of reserved balls is 0. In this case, it is confirmed whether or not the image display unit 50 is changing the special symbol (whether or not it is in the standby screen) (S1102). If it is not in the standby screen, standby screen setting processing for setting the image display unit 50 to the standby screen is performed (S1103), and if it is in the standby screen, the special symbol standby processing (S1100) is ended as it is. When the number of reserved balls is not 0 in the confirmation of the number of reserved balls (S1101), a special symbol jackpot determination process (S1110), a special symbol selection process (S1120), a special symbol variation pattern creation process (S1130), a special symbol Symbol random number shift processing (S1140) and special symbol variation start setting (S1150) are executed.

  In the special symbol jackpot determination process (S1110), as understood from the flowchart of FIG. 31, the jackpot determination random number stored in the RAM of the main control circuit 121 is loaded as a determination value (S1111), and the probability variation state The address of the RAM in which the jackpot determination value table that defines the jackpot value in the time (high probability state) and the normal gaming state (low probability state) is stored is set (S1112). Subsequently, it is confirmed whether or not the current probability change state (high probability state), that is, whether or not the probability change is in progress (S1113). The confirmation during the probability change is performed depending on whether the probability change flag provided in the main control circuit 121 is ON (high probability state) or OFF (low probability state). When the probability change is in progress, whether or not the jackpot is established is confirmed based on whether or not the jackpot winning value in the high probability state matches the jackpot winning determination random number loaded in S1111 (S1114). If it is not under certainty, whether or not the jackpot is established is confirmed based on whether or not the jackpot value in the low probability state matches the jackpot determination random number loaded in S1111 (S1115). In any case, when the match of the jackpot determination random number is confirmed, the jackpot is established, and the jackpot flag is set to ON (S1116). When the jackpot is not established in S1114 and S1115, the special symbol jackpot determination process (S1110) ends.

  In the special symbol selection process (S1120), as understood from the flowchart of FIG. 32, it is confirmed whether or not the jackpot flag is ON (S1121). If the jackpot flag is ON (the jackpot is established), the jackpot symbol is selected. The symbol based on the random number is set as a special jackpot symbol combination that is confirmed and stopped on the image display unit 50 (S1122).

  If the jackpot flag is not ON in S1121 (that is, if it is off), the reach random number obtained in the start winning opening switch detection process (S400) and stored in the RAM of the main control circuit is loaded, and the above reach is established. It is confirmed whether or not it matches the numerical value (S1123). If both values match, reach is established, and the special symbol data 1 acquired in the start winning a prize opening switch detection process (S400) and stored in the RAM is confirmed and stopped on the image display unit 50. It is set as a special symbol (S1124), 1 is added to the special symbol data 1 (S1125), and the data after the addition is set as a middle special symbol displayed on the image display unit 50 in a fixed stop (S1126).

  When the reach random number loaded in S1123 does not coincide with the reach establishment value, that is, when there is no reach, the extra special symbols 1, 2, and 3 created in the extra special symbol creation processing (S1010) are stored (set). The address value is set as the storage source address value (S1127), and then the addresses of the stop special symbols 1, 2, and 3 are set as the storage destination address value (S1128). Then, data is transferred from each storage source address to the storage destination address (S1129). The special symbol selection process (S1120) ends with the above processes. Stop special symbols 1, 2, and 3 are, in order, a stop left special symbol, a stop special symbol, and a stop right special symbol that are fixedly displayed on the image display unit 50.

  In the special symbol variation pattern creation process (S1130), as understood from the flowchart of FIG. 33, it is confirmed whether or not the jackpot flag is ON (S1131), and when the jackpot flag is ON (the jackpot is established) Any variation pattern is selected from the first table pattern of Table 1 (S1132). If the jackpot flag is not ON (that is, if it is off), one of the variation patterns is selected from the second table pattern of Table 2 (S1133). In any case, after the variation pattern is selected, other necessary processing is performed (S1134), and the special symbol variation pattern creation processing (S1130) ends.

  In selecting a variation pattern in each table pattern in the special symbol variation pattern creation process, an effect random number acquired in the start winning a prize opening switch detection process (S400) and stored in the RAM of the main control circuit is loaded. The variation pattern is selected by comparing this random number value with the effect random number value set for each variation pattern of each table pattern.

  In the special symbol random number shift process (S1140), in the data storage area of the reserved ball number in the RAM in the main control circuit, the data of the reserved ball number stored in the storage area of the load rank (reading rank) first address is Due to the fact that the seats are loaded and vacant due to the above-described processing, the data of the number of reserved balls stored in the address of the second or lower load order is shifted by one to increase the load order by one. As can be understood from the flowchart of FIG. 34, first, 1 is subtracted from the number of reserved balls stored in the RAM of the main control circuit (S1141). Specifically, if the number of reserved balls is 3, it becomes 2. Next, the data corresponding to each number of reserved balls is shifted to the RAM address of the number of reserved balls obtained by subtracting 1 from each number of reserved balls (S1142). Subsequently, 0 is set to the RAM address corresponding to the highest number of balls held (the last in the loading order, the fourth in the embodiment) (S1143).

  In the special symbol variation start setting (S1150), the special operation status is set to 2, and at the same time, necessary processing relating to the special symbol variation start is performed. After this process (S1150), the special symbol standby process (S1100) ends.

  As understood from the special operation process (S1000) of FIG. 28, the special symbol variation process (S1200) performed when the special operation status is 2 in S1030, as understood from the flowchart of FIG. First, special operation timer determination processing (S1201) is performed. In this process, a special operation timer corresponding to the variation time (msec) of the variation pattern selected from each table pattern (see Tables 1 and 2) is set and this subtraction is performed. Therefore, it is confirmed whether or not the special operation timer = 0, that is, whether or not the variation time of the variation pattern has ended (S1202). If the special operation timer is not 0, that is, if there is a remaining variation time, the special symbol variation processing ( S1200) ends. When the special operation timer is 0, that is, when the variable time is over, the address of the variable stop symbol table is set (S1203), the variable stop symbol data is stored (S1204), and the special operation status is set to 3. (S1205), other necessary processing (S1206) is executed, and the special symbol variation processing (S1200) ends.

  Similarly, as understood from the special operation process (S1000) of FIG. 28, in the special symbol confirmation process (S1300) performed when the special operation status is 3 in S1040, as understood from the flowchart of FIG. It is confirmed whether or not the jackpot flag is ON (S1301). If the jackpot flag is ON (successful jackpot is established), the round counter is set (S1302) and the special operation status is set to 4 (S1303). When the jackpot flag is not ON (that is, when it is off), the special operation status is set to 1 (S1304). After each special operation status is set, the special symbol confirmation process (S1300) ends. In the embodiment, the round counter is set to 15 times.

  Further, as understood from the special operation process (S1000) of FIG. 28, when the special operation status does not correspond to any of 1, 2, 3 in S1020, S1030, S1040, that is, when the special operation status is 4. In the special electric accessory processing (S1400) to be performed, as is understood from the flowcharts of FIG. 37 and FIG. 38, is the probability variation flag set to OFF (S1401) and whether the big hit end flag is ON (big hit game end)? It is confirmed whether or not (S1402). If the jackpot end flag is not ON, that is, if the jackpot game is not ended, it is confirmed whether the open / close door 601 of the big winning device 60 is currently open (S1403), and the big winning device 60 is not open (closed). In this case, it is confirmed whether or not it is the opening time of the big winning device 60, that is, whether or not the big hit operation timer is 0 (S1404). Here, when the jackpot operation timer is 0, the winning device 60 is released (S1410), and when the jackpot operation timer is not 0, the special electric accessory processing (S1400) is terminated.

  If the open / close door 601 of the grand prize winning device 60 is currently open in S1403, whether the number of winning balls detected in the big prize winning device 60 (winning ball count switch) has reached 10 (S1420), round It is confirmed whether the time (29.5 seconds in the embodiment) has elapsed (S1421) or not, and if not, the special electric accessory processing (S1400) is terminated. On the other hand, when any of the ten winnings and the round time has been satisfied, the opening / closing door 601 of the big winning device 60 is closed (S1430), and one is subtracted from the value of the round counter. (S1440). In the special winning device closing process (S1430), a command for closing the special winning device is set in the output buffer so as to be transmitted to the display control circuit 161 as well. Subsequently, whether or not the round counter is 0, that is, the end of the special game (big hit game) state is confirmed (S1441), and if the round counter is not 0, the special electric accessory processing (S1400) is ended as it is. . When the round counter is 0, the jackpot end processing is performed (S1442), and the jackpot random number data stored in the reserved symbol number storage area for special symbols in the main control circuit RAM is displayed together with the jackpot end command. It is set in the output buffer so that it can be transmitted to the circuit 161. Thereafter, the jackpot end flag is set to ON (S1443), and the special electric accessory processing (S1400) ends.

  In S1402, if the jackpot end flag is ON (that is, the jackpot game end), the jackpot end flag is set OFF (S1444), and the jackpot flag is also set OFF (S1445). Next, it is confirmed whether or not the confirmed stop symbol is a probability variation symbol (an odd number in the embodiment) (S1446). If it is a probability variation symbol, the probability variation flag is set to ON (S1447), and the special operation status is set. Is set to 1 (S1448), and the special electric accessory processing (S1400) ends. If the confirmed stop symbol is a symbol different from the probability variation symbol, the special operation status is set to 1 as it is (S1448), and the special electric accessory processing (S1400) ends.

  In the special winning equipment opening process (S1410) executed in the special electric accessory process (S1400), as can be understood from the flowchart of FIG. 39, the open / close suppression piece 630 is changed to the unlocked position, and the open / close door 601 is In the first state, the special winning device 60 is opened (S1411). Reference is made to FIGS. 5, 6, etc. disclosed as the first embodiment for the variable mode of the opening / closing suppression piece 630.

  Similarly, in the special winning device closing process (S1430) executed in the special electric accessory process (S1400), as can be understood from the flowchart of FIG. 40, the opening / closing suppression piece 630 is changed to the locked position, and at the same time the opening / closing door 601 is opened. Is in the second state, and the special winning device 60 is closed (S1431). Reference is made to FIGS. 10 and 11 disclosed as the first embodiment for the variable mode of the opening / closing suppression piece 630.

  In the interrupt process (S10) disclosed in FIG. 26, in the reserved ball number process (S1500) subsequent to the special operation process (S1000), as is understood from the flowchart of FIG. Loaded (S1501), the loaded number of reserved balls is set in the output buffer (S1502), and this process (S1500) ends.

  In other processing (S1600), processing necessary for other games is properly performed. As described above, the interrupt process (S10) is completed through the disclosed processes.

  The disclosed series of control and processing is processing related to the big winning device 60 of the first embodiment. Therefore, when the big prize device 60A disclosed in FIG. 14 to FIG. 22 is adapted to the second embodiment, the big prize device opening process (S1410) and the big prize device closing process (S1430) are performed next. The prize winning device opening process (S′1410) and the prize winning device closing process (S′1430) are changed as shown. Since other processes are common, specific description is omitted.

  In the special winning device opening process (S′1410) of the second embodiment executed in the special electric accessory process (S1400), as can be understood from the flowchart of FIG. 42, the open / close suppression piece 630A is changed to the unlocked position. (S'1411). Subsequently, the opening / closing door 601 is opened (variable to the first state) (S′1412). Reference is made to FIGS. 14 and 15 disclosed as the second embodiment for the variable mode of the opening / closing suppression piece 630A.

  Similarly, in the special winning device closing process (S′1430) of the second embodiment executed in the special electric accessory process (S1400), as understood from the flowchart of FIG. 43, the open / close suppression piece 630A is moved to the locked position. Variable (S'1431). Subsequently, the opening / closing door 601 is closed (variable to the second state) (S′1432). Reference is made to FIGS. 19 and 20 disclosed as the second embodiment for the variable mode of the opening / closing suppression piece 630A.

  The operation of the open / close door and the open / close restraining piece will be described with respect to the large winning device including the configuration of the third embodiment disclosed in FIGS. In the third embodiment, a special electric accessory process (S ″ 1400) shown in the flowchart of FIG. 44 is executed instead of the special electric accessory process (S1400) of the first and second embodiments. In the special electric accessory processing (S ″ 1400), the probability variation flag is set to OFF (S ″ 1401), and it is confirmed whether or not the jackpot end flag is ON (jackpot game end) (S ″ 1402). If the jackpot end flag is not ON, that is, if the jackpot game is not ended, it is confirmed whether or not the open / close door 601 of the big winning device 60 is currently open (S "1403), and the big winning device 60 is not open (closed). Middle), it is confirmed whether or not it is the opening time of the big winning device 60, that is, whether or not the big hit operation timer is 0 (S "1404). Here, when the jackpot operation timer is 0, the winning device 60 is released (S ″ 1410), and when the jackpot operation timer is not 0, the special electric accessory processing (S ″ 1400) is performed as it is. finish.

  In S "1403, when the open / close door 601 of the grand prize winning device 60 is currently open, it is confirmed whether or not five game balls have been entered by the winning ball count switch 604 in the big prize winning device (S" 1415). ) When five balls are confirmed, the opening / closing suppression piece 630B is changed to the second guidance state (see FIG. 24) (S ″ 1416), and the special electric accessory processing (S ″ 1400) is terminated. Subsequently, in the case where five balls have not been confirmed in the large winning device (in the case of less than five balls), the number of winning balls detected in the large winning device 60 (winning ball count switch). Whether it has reached 10 (S ″ 1420) or the round time (29.5 seconds in the embodiment) has passed (S ″ 1421). The special electric accessory processing (S "1400) is terminated. On the other hand, when either of the ten winnings or the round time has been satisfied, the closing process of the open / close door 601 of the large winning device 60 is performed. (S ″ 1430), 1 is subtracted from the value of the round counter (S ″ 1440). In the big prize device closing process (S ″ 1430), the command for closing the big prize device is a display control circuit 161. Can also send to output buffer It is set. Subsequently, whether or not the round counter is 0, that is, the end of the special game (big hit game) state is confirmed (S "1441). If the round counter is not 0, the special electric accessory processing (S" 1400) is performed as it is. ) Ends. When the round counter is 0, the jackpot end process is performed (S "1442), and the jackpot random number data stored in the reserved ball number storage area for the special symbol in the main control circuit RAM is displayed together with the jackpot end command. It is set in the output buffer so that it can be transmitted to the display control circuit 161. Thereafter, the jackpot end flag is set to ON (S ″ 1443), and the special electric accessory processing (S ″ 1400) ends.

  In S ″ 1402, the process when the jackpot end flag is ON (the jackpot game end), that is, when the jackpot game is ended is the same as S1444 to S1448 of the first embodiment disclosed in FIG. Omitted.

  In the special winning equipment release process (S "1400) executed in the third embodiment, as shown in the flowchart of FIG. 45, the big winning device opening process (S" 1410) is a jackpot symbol? (S ”1411) Specifically, the acquired value of the jackpot symbol random number counter is“ 1 ”,“ 3 ”,“ 5 ”,“ 7 ”,“ 9 ”,“ 11 ”. If the jackpot symbol is a probability variation symbol, the opening / closing suppression variation 630B is changed to the first induction state (see FIG. 23) (S "1412), and the jackpot symbol is certain variation. If it is not a symbol, the opening / closing restraining change 630B is changed to the second guiding state (S ″ 1412), so that the opening / closing door 601 is opened (S ″ 1414).

  In the second guiding state in S ″ 1413, in addition to the state in which the game ball cannot be entered as disclosed in FIG. It is possible to set the position state in which the level of ease (difficulty of entering the ball) is set high and low, so that the easy guidance state, the middle guidance state, the difficult guidance state, and the second guidance state in order from the first guidance state. It is also possible to swing between the easy guidance state and the difficult guidance state at a predetermined cycle.

  In the special winning equipment closing process (S ″ 1430) executed in the special electric accessory process (S ″ 1400) of the third embodiment, as shown in the flowchart of FIG. 46, the open / close door 601 is closed. (S ″ 1431), the opening / closing suppression piece 630B is changed to the second guiding state (S ″ 1432).

  In addition to the special symbol jackpot determination process (S1110) described above, the special electric accessory process (S "1400), the big prize device opening process (S" 1410) incorporated therein, and the big prize device closing process (S ") 1430), the opening condition of the open / close door 601 depends on the game determination result, and is established by becoming a game mode in which a game privilege including a case where it is a win can be given. When the opening condition of the door 601 is satisfied, the opening / closing inhibiting member 630B can operate without being hindered from changing from the second state (closed) to the first state (opening) of the opening / closing door. 630B is in the first induction state of Fig. 23. Alternatively, the open / close suppression member 630B can be in any one of the second induction states including between the easy induction state and the difficult induction state. . Thus, at the time the jackpot, is performed opening of door of the special winning device, it is possible to prevent illegal for round state when special game execution.

  Further, the open / close restraining member 630B shifts to the second guidance state due to a predetermined number (5 in the embodiment) of entering the entrance of the winning device 60 (the winning device entering entrance 603). Therefore, excessive entry of game balls into the big winning device is suppressed. For this reason, even when the grand prize winning device is opened, the ease of entering the ball changes, and the fun of demonstrating the skill of entering the ball during the jackpot game (special game) is created. Further, in addition to the predetermined number of balls, the opening / closing suppression member 630B can be shifted to the second guiding state due to the elapse of a predetermined time from the opening of the big winning device. In this case, a timer for measuring the round time used in S ″ 1421 can be used, for example, to shift to the second induction state after 15 seconds. In addition, in the embodiment, in the first and second induction states, The variable is set based on whether or not the jackpot symbol is a probabilistic symbol.In addition to this, the first and the second due to the occurrence of a small jackpot (per normal symbol) during the jackpot game (special game) It is also possible to change the two-lead state.

  The present invention is not limited to the above-described embodiments, and a part of the configuration can be changed as appropriate without departing from the spirit of the invention. Although the embodiment has been described using the large winning device as the gaming privilege granting device, it is of course applicable to other winning devices. Further, the number of opening / closing restraining members (opening / closing restraining pieces) is not limited to one, and for example, two or more can be provided on the left and right of the big winning device. Furthermore, the installation position of the opening / closing suppression member (opening / closing suppression piece) is appropriate as long as the locking position and the non-locking position can be taken with respect to the opening / closing door (opening / closing member) of the prize winning device. In addition, it is not always necessary to use the base for attaching the big winning device, and it can be directly installed on the game board. The shape of the opening / closing restraining member (opening / closing restraining piece) is not limited to the illustrated embodiment.
