As described above, some gaming machines such as pachinko machines have a movable accessory or the like to improve the interest of the player. For example, a shutter accessory is provided as a movable accessory, and a part or all of the display unit (display area) of the display device is temporarily shielded by a shielding plate in conjunction with various display effects performed in a liquid crystal display device or the like. An effect etc. are performed (for example, refer patent document 1).

However, in recent gaming machines such as pachinko machines, the display device (display unit) tends to be enlarged in order to improve the interest of the player. Therefore, if the entire display portion of the display device is to be shielded with a single shielding plate, a shielding plate having a size equivalent to the size of the display portion is required. For this reason, a large space for storing the shielding plate is required at the normal time when the shielding plate is retracted from the display unit.

A gaming machine such as a pachinko machine must be provided with a large number of devices such as a display device in a limited installation space, so that the size and installation space of a shutter accessory are also limited. Therefore, it is difficult to ensure a large accommodation space for accommodating a large shielding plate.

On the other hand, when the shielding plate is divided into a plurality of parts, a plurality of drive sources (motors, etc.) that move the plurality of shielding boards, a plurality of power transmission members that are linked to this, and the like must be provided. Concerns such as an increase in the number of parts arise.

In any case, the current shutter function cannot sufficiently cope with the enlargement of the display device.

Note that the above-described problem is not limited to pachinko machines, but also applies to other gaming machines such as slot machines in which many devices are installed in a limited installation space. Further, the object to be shielded is not limited to the display unit of the display device, and may be another object such as an accessory.

The present invention has been made to solve the above-described problems, and its purpose is to suppress an increase in the number of parts such as a mechanism that shields a predetermined object such as a display unit or an accessory of a display device.

A force in a direction intersecting the driving direction of the power transmission member is applied to the set), and the first shielding member (shielding member set) is rotated. As a result, the configuration of the means 1 and the like can be realized with a relatively simple configuration, and the configuration can be further simplified.

  Note that “extending in an intersecting manner” means, for example, being formed in a straight line along the intersecting direction, and of course extending in a curved line so as to have the intersecting direction in the tangential direction. It is also included. For example, the first cam portion includes a non-interference section at the time of relative displacement extending along the horizontal direction, and an action section at the time of set rotation displacement extending obliquely upward from one end portion thereof.

  Means 5. The second cam portion includes a non-interference section at the time of set rotation displacement that does not interfere with the operation of the second operated portion accompanying the rotation displacement when the shielding member set is rotated and displaced. 5.

For example, it is possible to rotate the second shielding member with the axis near the center of the object. As a result, the problems described in the operation and effect of the means 10, that is, the limitation of the shielding area is reduced.

  Means 12. 12. The means according to claim 1, further comprising at least one third shielding member that moves following (interlocking with) the second shielding member based on an action from the second shielding member. Gaming machine.

  According to the means 12, by providing the third shielding member that moves following the second shielding member, more members can be moved by one drive source and power transmission member to shield a wider area of the object. be able to.

  Here, “moving following the second shielding member” means that, by receiving the action from the second shielding member without directly receiving the power transmission from the power transmission member like the second shielding member, Or it means that it is comprised so that it can operate | move by receiving an effect | action via the member which received the effect | action from the said 2nd shielding member.

A configuration in which a link mechanism is separately provided can be mentioned. However, if the third link mechanism is provided, the driving mechanism of the shielding device may be more complicated. A configuration in which the third shielding member is driven by the second shielding member as described above is preferable. On the other hand, when the engaging means is provided, the number of portions where the second shielding member and the third shielding member overlap or the thick portion increases. For this reason, for example, when the shielding member is made of a semi-transparent member or the like, there is a possibility that the player may visually recognize the spots on each part of the shielding member. Therefore, in such a case, it may be preferable to provide the third link mechanism.

  Means 13. The gaming machine according to any one of means 1 to 12, wherein the first cam portion and the second cam portion are formed on the power transmission member.

  According to the means 13, it is possible to simplify the configuration by providing both cam portions on the power transmission member, and it is possible to further enhance the operational effects of the means 1 and the like.

It is designed to be operated repeatedly. More specifically, when a game ball wins the first opportunity corresponding unit 33, the special display device 39 displays the three-color LEDs at a high speed, such as red → green → blue → red →. When a predetermined time elapses, it is determined and displayed in one of the colors. High-speed color change display means, for example, that red, green, and blue are displayed in order every 4 msec. At this time, a special gaming state occurs when the decision display is made in red or green (for example, when it is stopped for a few seconds), that is, when a big win lottery is won. Here, red or green is a display showing a big hit. In particular, red is a display indicating that the game mode after the jackpot ends is a high probability mode described later, and green is a display indicating that the game mode after the jackpot ends is a time reduction mode described later. For this reason, when the special display device 39 determines and displays the three-color LED in red or green, a combination of specific symbols is supplementarily displayed on the decorative symbol display device 42. The large winning opening of the variable winning device 32 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win a prize (a big hit state). More specifically, a predetermined time (for example, 29 seconds) or a predetermined number (for example, 10) of winnings is regarded as one round (special prize state), and the large winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times (a predetermined number of rounds).

  The non-interference section 781b extends along the inner peripheral edge of the ring member 720. That is, the non-interference section 781b extends along the rotation direction (drive direction) of the ring member 720. On the other hand, the action section 781a is gently curved while gradually changing the direction of the tangential direction from the end position on the counterclockwise direction side of the non-interference section 781b, and is substantially orthogonal to the outer peripheral edge of the ring member 720. So as to extend. That is, it extends so as to intersect at least the driving direction of the ring member 720. In the present embodiment, a shape is formed by connecting a plurality of arcs having different curvatures. This is because the rotational displacement amount of the shutter piece set 715 around the rotational shaft portion 745 and the rotational displacement amount of the ring member 720 are taken into account, so that the shutter piece set 715 can be more smoothly rotationally displaced. It is.

  Of the inner wall portions constituting the first cam groove 781, the inner wall portion acting on the first engagement shaft portion 760 differs depending on the driving direction of the ring member 720. Therefore, in the longitudinal direction of the first cam groove 781, the position at which the action section 781a and the non-interference section 781b are switched differs depending on the driving direction of the ring member 720, but in FIG. It is shown. Of course, the portion acting on the first engagement shaft portion 760 differs slightly depending on which position the shutter piece set 715 is engaged with as long as play is provided.

  The second cam groove 782 has an action section 782a that acts on the second engaging shaft portion 763 when the fourth shutter piece 734 is relatively rotated and displaced, and a second cam groove 782 that moves when the shutter piece set 715 is integrally rotated and displaced. A non-interference section 782b that does not interfere with the engagement shaft portion 763 (the power of the ring member 720 is not transmitted). The action section 782a corresponds to the action section during relative displacement in the present embodiment, and the non-interference section 782b corresponds to the non-interference section during pairing rotation displacement.

  The non-interference section 782b of the second cam groove 782 is curved so as to be substantially parallel to the action section 781a of the first cam groove 781. More specifically, the non-interference section 782b is formed in accordance with the locus drawn by the second engagement shaft portion 763 when the shutter piece set 715 is integrally rotated and displaced. This is because the shutter piece set 715 is more smoothly rotationally displaced as in the operation section 781a of the first cam groove 781.

  On the other hand, the action section 782a of the second cam groove 782 is formed at a position protruding from the inner peripheral edge of the ring member 720 by a rib or the like so as to be connected to the non-interference section 782b.

  The action section 782a of the second cam groove 782 is extremely shorter than the non-interference section 782b, and terminates in the vicinity of the boundary between the action section 781a and the non-interference section 781b of the first cam groove 781. This is because the relative rotation displacement operation (separation operation) of the fourth shutter piece 734 is started immediately after the integral rotation displacement of the shutter piece set 715 is completed, as will be described later.

  Similar to the first cam groove 781, among the inner wall portions constituting the second cam groove 782, the inner wall portion that acts on the second engagement shaft portion 763 differs depending on the driving direction of the ring member 720. Therefore, in the longitudinal direction of the second cam groove 782, the position at which the action section 782a and the non-interference section 782b are switched differs depending on the driving direction of the ring member 720, but in FIG. It is shown. Of course, the portion that acts on the second engagement shaft portion 763 is slightly different depending on which position the shutter piece set 715 is engaged with as long as play is provided.

  A gear portion 784 is formed on the outer peripheral edge of the ring member 720 in a predetermined section.

  On the other hand, as shown in FIG. 5 and the like, a motor unit 785 serving as a drive source is attached to the upper right portion of the casing 701 (rear frame 704). The motor unit 785 includes a step motor (not shown), a gear mechanism that transmits the driving force of the motor to the ring member 720, and the like.

  As shown in FIG. 11 and the like, a notch portion 793 is provided from the base portion 706 to the outer peripheral wall portion 708 at a corresponding portion of the rear frame 704, and the motor unit 785 has a notch 793 through the notch portion 793. The gear mechanism and the gear portion 784 of the ring member 720 are engaged with each other.

  The step motor of the motor unit 785 is rotation-controlled by the applied drive pulse, and the rotation angle changes according to the number of input pulses. That is, the amount of rotational displacement of the ring member 720 can be controlled by adjusting the drive pulse. As a result, the amount of rotational displacement of the ring member 720 from the reference position can be grasped by monitoring the number of input drive pulses.

  In addition, photosensors 795a, 795b, and 795c for grasping the rotational position of the ring member 720 are attached to the base portion 706 of the rear frame 704 at three locations. On the other hand, a light shielding portion 797 is formed on the back surface of the ring member 720 (see FIG. 16). Then, the ring member 720 is rotationally displaced, and the light shielding portion 797 is detected by the photosensors 795a to 795c at the respective positions, whereby the reference position and the rotational displacement amount of the ring member 720 are grasped.

  Also, as shown in FIG. 10 and the like, four sets of auxiliary grooves 798 are formed on the back side of the front frame 703 corresponding to each shutter piece set 715. The auxiliary groove 798 is for assisting the displacement operation of the fourth shutter piece 734, and the other end of the second engagement shaft portion 763 of the fourth shutter piece 734 is inserted. Therefore, the auxiliary groove 798 is formed in accordance with the locus drawn by the second engagement shaft portion 763. In the present embodiment, only the auxiliary groove 798 for assisting the fourth shutter piece 734 (second engagement shaft portion 763) is provided. Of course, the first shutter piece 731 (first engagement shaft) is provided. An auxiliary groove for assisting the portion 760) may be provided.

  Next, the operation of the shutter piece set 715 will be described with reference to FIGS. In FIG. 17 to FIG. 22, in order to make the operation of the shutter piece set 715 easier to understand, illustrations other than main members such as the rear frame 704, the shutter piece set 715, and the ring member 720 are omitted, and the shutter piece set 715 ( Scatter patterns are given to the portions of the shutter pieces 731 to 734).

  Normally, the shutter piece set 715 is entirely accommodated in the casing 701 in a state where the first to fourth shutter pieces 731 to 734 are superimposed (see FIG. 17). In this state, as described above, the inner peripheral wall portions 740 of the front frame 703 and the rear frame 704 are arranged so that the inner peripheral wall portion 740 of the first shutter piece 731 fills the cutout portion 770 of the inner peripheral wall portion 709 of the front frame 703. 709 and 710 are substantially flush with each other and constitute a part of the window 43 a of the shutter accessory 43. This state corresponds to the normal state (reference state) of the shutter piece set 715, and the window 43a of the shutter accessory 43 is fully opened.

  When the ring member 720 is rotated counterclockwise by the motor unit 785 from this state, the first engagement shaft portion 760 of the first shutter piece 731 located in the vicinity of the outer peripheral edge portion of the ring member 720. Is gradually moved toward the inner peripheral side of the ring member 720 while being pushed counterclockwise by the curved wall portion on the clockwise direction side of the action section 781a of the first cam groove 781 (see FIG. 18). ). Thereby, the shutter piece set 715 (shutter pieces 731 to 734) is integrally rotated and displaced in the counterclockwise direction around the rotation shaft portion 745. Then, the shutter piece set 715 protrudes to the inside of the window 43 a of the shutter accessory 43 through the notch 770 of the inner peripheral wall 709 of the front frame 703. That is, in a state where the decorative symbol display device 42 is assembled behind the shutter accessory 43, the shutter piece set 715 pops out in front of the display unit 42a of the decorative symbol display device 42. The counterclockwise direction corresponds to the first driving direction or the first direction in the present embodiment.

  At this time, the second engagement shaft portion 763 of the fourth shutter piece 734 moves along the non-interference section 782b of the second cam groove 782 so as not to interfere with the rotation operation of the shutter piece set 715. However, the second cam groove 782 does not interfere with the operation of the fourth shutter piece 734 (second engagement shaft portion 763) depending on the up / down / left / right assembling positions of the shutter piece set 715, but the fourth shutter piece 734 is not affected. It plays a role of restricting useless movement of the (second engagement shaft portion 763) or assisting rotational displacement. For example, in the shutter piece set 715 located on the lower side, the free end side (second engagement shaft portion 763 side) of the fourth shutter piece 734 is separated from the first shutter piece 731 due to its own weight when integrally displaced. However, this movement is restricted by the curved wall portion of the second cam groove 782. Similarly, useless movement of the fourth shutter piece 734 (second engagement shaft portion 763) is also restricted by the auxiliary groove 798 of the front frame 703.

  As the ring member 720 further rotates, the tips of the four shutter piece sets 715 approach each other toward the center of the window 43 a of the shutter accessory 43. Then, when the ring member 720 is rotated by a predetermined amount, the tips of the four shutter piece sets 715 are substantially in contact with each other at the central portion of the window 43a of the shutter accessory 43 (see FIG. 19). In this state, the window 43a of the shutter accessory 43 is divided into four parts, and the player can visually recognize the display part 42a of the decorative symbol display device 42 in four parts.

  Note that the angle α of the tip of each first shutter piece 731 viewed from the front of the shutter accessory 43 is 90 ° (see FIG. 19). As a result, when the tips of the first shutter pieces 731 of the four shutter piece sets 715 are substantially in contact with each other at the central portion of the window portion 43a of the shutter accessory 43, the vicinity of the central portion of the window portion 43a. Is shielded with almost no gap.

  In this state, the first engagement shaft portion 760 of the first shutter piece 731 moves to the non-interference section 781b of the first cam groove 781, and the second engagement shaft portion 763 of the fourth shutter piece 734 is , The second cam groove 782 moves to the action section 782a.

  From this point, when the ring member 720 continues to rotate in the counterclockwise direction, the second engagement shaft portion 763 of the fourth shutter piece 734 moves in the clockwise direction of the action section 782a of the second cam groove 782. Pushed in the counterclockwise direction by the end wall portion, the free end side (second engagement shaft portion 763 side) of the fourth shutter piece 734 begins to separate from the first shutter piece 731 (see FIG. 20). That is, the fourth shutter piece 734 is displaced by relative rotation with the free end side of the first shutter piece 731 as an axis.

  At this time, since the first engagement shaft portion 760 of the first shutter piece 731 is in the non-interference section 781b of the first cam groove 781, the driving force of the ring member 720 is the first shutter piece 731 (first engagement shaft portion). 760). In other words, the ring member 720 transmits a driving force to the fourth shutter piece 734 (second engagement shaft portion 763) without interfering with the first shutter piece 731 (first engagement shaft portion 760). be able to. Accordingly, the fourth shutter piece 734 is opened from the first shutter piece 731 while the first shutter pieces 731 are held in a state of being substantially in contact with each other at the central portion of the window 43a.

  The non-interference section 781b of the first cam groove 781 does not interfere with the operation of the first shutter piece 731 (first engagement shaft portion 760), but the first shutter piece 731 (first engagement shaft portion 760). Plays a role in regulating the useless movement of For example, in the radial direction of the ring member 720, the first shutter piece 731 is rotationally displaced about the rotational shaft portion 745 due to stress when the fourth shutter piece 734 is rotationally displaced (opening operation). Movement is regulated.

  Further, when the ring member 720 continues to rotate counterclockwise, the fourth shutter piece 734 continues to open from the first shutter piece 731. With this movement, the convex portion 756 of the fourth shutter piece 734 is caught by the end of the long hole 755 of the third shutter piece 733. Then, the third shutter piece 733 is pulled out from the back side of the first shutter piece 731 so as to be pulled by the fourth shutter piece 734, and the third shutter piece 733 is driven (interlocked) with the movement of the fourth shutter piece 734. Starts to open from the first shutter piece 731 (see FIG. 21). That is, the third shutter piece 733 is also relatively rotated and displaced with the free end side of the first shutter piece 731 as an axis, similarly to the fourth shutter piece 734.

  Further, when the ring member 720 continues to rotate counterclockwise, the fourth shutter piece 734 and the third shutter piece 733 continue to open from the first shutter piece 731. With this operation, the convex portion 754 of the third shutter piece 733 is caught by the end of the long hole 753 of the second shutter piece 732. Then, the second shutter piece 732 is pulled out from the back side of the first shutter piece 731 so as to be pulled by the third shutter piece 733 and is driven (interlocked) by the movement of the fourth shutter piece 734 and the third shutter piece 733. Then, the second shutter piece 732 also starts to open from the first shutter piece 731. That is, the second shutter piece 732 is also relatively rotated and displaced about the free end side of the first shutter piece 731 as an axis, similarly to the fourth shutter piece 734 and the third shutter piece 733.

  When the ring member 720 is rotated by a predetermined amount, the fourth shutter piece 734 of the predetermined shutter piece set 715 is substantially in contact with the first shutter piece 731 of another adjacent shutter piece set 715 (FIG. 22). In this state, the window portion 43a of the shutter accessory 43 is fully closed by the four shutter piece sets 715, and the player cannot visually recognize the display portion 42a of the decorative symbol display device 42.

  On the other hand, when the four shutter piece sets 715 return to the original state, the procedure reverse to the above procedure is followed. That is, when the motor unit 785 rotates in the reverse direction and the ring member 720 is rotated in the clockwise direction, the second engagement shaft portion 763 of the fourth shutter piece 734 is moved to the action section 782a of the second cam groove 782. The fourth shutter piece 734 is pushed in the clockwise direction by the curved wall portion on the counterclockwise direction, and the fourth shutter piece 734 is relatively rotated in the clockwise direction with the free end side of the first shutter piece 731 as an axis. To start. The clockwise direction corresponds to the second driving direction or the second direction in the present embodiment.

  When the ring member 720 continues to rotate in the clockwise direction, the fourth shutter piece 734 continues the collective operation to approach the first shutter piece 731, and the fourth shutter piece 734 enters to be hidden behind the third shutter piece 733. .

  And if the convex part 756 of the 4th shutter piece 734 is hooked in the edge part of the long hole 755 of the 3rd shutter piece 733, the 3rd shutter piece 733 will follow the movement of the 4th shutter piece 734, and the 3rd shutter piece 733 will be watchpiece. Start moving in the direction of rotation.

  When the ring member 720 continues to rotate in the clockwise direction, the fourth shutter piece 734 and the third shutter piece 733 approach the first shutter piece 731, and the fourth shutter piece 734 and the third shutter piece 733 are in the second direction. It enters so as to be hidden behind the shutter piece 732.

  And if the convex part 754 of the 3rd shutter piece 733 is hooked in the edge part of the long hole 753 of the 2nd shutter piece 732, it will follow to the movement of the 4th shutter piece 734 and the 3rd shutter piece 733, and will be 1st. 2 The shutter piece 732 starts to move in the clockwise direction.

  Further, when the ring member 720 continues to rotate in the clockwise direction, the second to fourth shutter pieces 732 to 734 enter so as to be hidden behind the first shutter piece 731.

  During the movement of the second to fourth shutter pieces 732 to 734 as described above, the driving force of the ring member 720 is the first shutter piece 731 (first shutter) as in the case of the opening operation. It is not transmitted to the engaging shaft portion 760). That is, the ring member 720 can transmit the driving force to the fourth shutter piece 734 (second engagement shaft portion 763) without interfering with the first shutter piece 731 (first engagement shaft portion 760). it can. Accordingly, the second to fourth shutter pieces 732 to 734 are gathered to the first shutter piece 731 while the first shutter pieces 731 are held in a state of being substantially in contact with each other at the central portion of the window portion 43a. .

  When the ring member 720 continues to rotate in the clockwise direction, the first engagement shaft portion 760 of the first shutter piece 731 moves to the action section 781a of the first cam groove 781, and the second shutter piece 734 has the second engagement portion 781a. The engagement shaft portion 763 moves to the non-interference section 782b of the second cam groove 782. Then, the first engagement shaft portion 760 of the first shutter piece 731 is gradually pushed in the clockwise direction by the counterclockwise curved wall portion of the action section 781a of the first cam groove 781 while being gradually rotated in the ring direction. It moves to the outer peripheral side of the member 720. Accordingly, the shutter piece set 715 (the shutter pieces 731 to 734) is integrally rotated and displaced in the clockwise direction around the rotation shaft portion 745. At this time, the second engagement shaft portion 763 of the fourth shutter piece 734 moves along the non-interference section 782b of the second cam groove 782 so as not to interfere with the rotation operation of the shutter piece set 715.

  In this manner, when the shutter piece set 715 is immersed in the casing 701 and the shutter piece set 715 returns to the normal state (reference state), the window 43a of the shutter accessory 43 is fully opened.

  In this embodiment, since the main control device 261 is stored in the board box 263 that is strictly sealed, it is difficult to perform an illegal act such as sending some illegal signal to the main control device 261. For this reason, it is difficult to illegally turn on the LED of the special display device 39 that is directly controlled by the main control device 261 in a “red” or “green” jackpot. Therefore, the decorative symbol display device 42 is displayed as if it was a big hit, and the big winning opening is forcibly opened using a cell or the like, so that a winning ball is obtained even if it is not a big hit. Even when such a fraudulent act is performed, such a fraudulent act can be easily found by confirming the lighting state of the special display device 39.

  Next, the electrical configuration of the pachinko machine 10 will be described. FIG. 23 is a block diagram showing an electrical configuration of the pachinko machine 10. The main control device 261 (main substrate) of the pachinko machine 10 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic device. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a RAM 503 that is a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. Various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The RAM 503 is a stack area that stores the contents of the internal registers of the CPU 501, the return address of a control program executed by the CPU 501, and a work area (work area) that stores various flags, counters, I / O values, and the like. ) And a backup area 503a.

  The RAM 503 is configured to retain (backup) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, and is stored in the stack area, work area, and backup area 503a. All data is backed up.

  In the backup area 503a, when the power is cut off due to a power failure or the like, the power of the pachinko machine 10 is restored to the state before the power is turned off when the power is turned on again. (Similarly) is an area for storing stack pointers, values of registers, I / O, and the like. Writing to the backup area 503a is executed when the power is turned off by normal processing (see FIG. 26), and conversely, returning of each value written to the backup area 503a includes turning on the power (including turning on the power due to power failure cancellation). The same processing is performed in the main process (see FIG. 25). Note that a power failure signal SK1 output from a power failure monitoring circuit 542, which will be described later, is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 501 when a power failure occurs due to the occurrence of a power failure or the like. Due to the occurrence, the power failure process (NMI interrupt process) of FIG. 28 is immediately executed.

  Note that if data stored in at least the stack area and the backup area 503a is backed up, it is not always necessary to back up data stored in all areas. For example, the data stored in the stack area and the backup area 503a may be backed up, and the data stored in the work area may not be backed up.

  An input / output port 505 is connected to the CPU 501 incorporating the ROM 502 and RAM 503 via a bus line 504 including an address bus and a data bus. A RAM erase switch circuit 543, a payout control device 311, a sub control device 262, a normal symbol display device 38, a special display device 39, and other switches (not shown) are connected to the input / output port 505. With this configuration, the normal symbol display device 38 and the special display device 39 described above are directly controlled by the main control device 261. On the other hand, the decorative symbol display device 42 is controlled via the sub-control device 262.

  The sub-control device 262 (sub-control board) includes a CPU 551 that is an arithmetic unit, various control programs executed by the CPU 551, a ROM 552 that stores fixed value data, and various control programs that are stored in the ROM 552.

Data is backed up. Note that if data stored in at least the stack area and the backup area 513a is backed up, it is not always necessary to back up data stored in all areas. For example, the data stored in the stack area and the backup area 513a may be backed up, and the data stored in the work area may not be backed up.

  The backup area 513a has a stack pointer, each register at the time of power off, each register, so that the power of the pachinko machine 10 is restored to the state before the power is turned off when the power is turned off. This is an area for storing values such as I / O. The writing to the backup area 513a is executed when the power is turned off by the main process (see FIG. 39), and the restoration of each value written in the backup area 513a is executed in the main process at the time of turning on the power (see FIG. 39). . Similarly to the CPU 501 of the main controller 261, the power failure signal SK1 is input to the NMI terminal of the CPU 511 from the power failure monitoring circuit 542 when the power is interrupted due to the occurrence of a power failure or the like. When input to the CPU 511, NMI interrupt processing as power failure processing is immediately executed.

  The payout permission flag is a flag for setting a prize ball payout permission, and is turned on when a specific command for permitting the payout of the prize ball is transmitted from the main control device 261 and received, and is initially set. It is turned off when it is restored before the process or power shutdown. In the present embodiment, the specific commands are: a payout initialization command for instructing the initial processing of the RAM 513 of the payout control device 311; There are three payout return commands to be transmitted in this case.

  The command reception flag is a flag for confirming whether or not the payout control device 311 has received a command, and is turned on when any command is received. Similar to the payout permission flag, an initial setting process or power-off is performed. It is turned off when it is returned to the front, and it is turned off when the received command is determined by a command determination process (see FIG. 41) described later.

  The command buffer is configured by a ring buffer that temporarily stores commands transmitted from the main control device 261. The ring buffer has a predetermined storage area, and commands are stored with regularity from the beginning to the end of the storage area. When commands are stored in all storage areas, the ring buffer is at the start of the storage area. The return command is configured to be updated. Therefore, when the command is stored and when the command is read, the storage pointer and the read pointer in the command buffer are updated, and the command is stored and read based on each pointer.

  An input / output port 515 is connected to the CPU 511 incorporating the ROM 512 and the RAM 513 through a bus line 514 including an address bus and a data bus. A RAM erase switch circuit 543, a main control device 261, a firing control device 312, a payout motor 358a, and the like are connected to the input / output port 515, respectively.

  The launch control device 312 permits or prohibits the launch of the gaming machine by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. Specifically, a firing permission signal is output from the payout control device 311, a sensor signal is detected that the player is touching the handle 18, and a firing stop switch that stops firing is operated. On the condition that it is not done, the launch motor 229 is driven, and the game ball is launched at an intensity corresponding to the operation amount of the handle 18.

  The display control device 45 executes the variable display of the decorative symbols on the decorative symbol display device 42 in accordance with an instruction from the sub-control device 262. The display control device 45 includes a CPU 521, a program ROM 522, a work RAM 523, a video RAM 524, a character ROM 525, a video display processor (VDP) 526, an input port 527, an output port 529, and bus lines 530 and 531. And. An input / output port 554 of the sub control device 262 is connected to the input port 527. Further, the CPU 521, the program ROM 522, the work RAM 523, and the VDP 526 are connected to the input port 527. An output port 529 is connected to the VDP 526 via a bus line 531, and a decorative symbol display device 42 as a liquid crystal display device is connected to the output port 529.

  The CPU 521 of the display control device 45 receives the display command transmitted from the sub-control device 262 via the input port 527 and analyzes the received command or performs predetermined arithmetic processing based on the received command to control the VDP 526 ( Specifically, internal command generation for VDP 526 is performed. Thereby, display control in the decorative symbol display device 42 is performed.

  The program ROM 522 is a memory that stores various control programs executed by the CPU 521 and fixed value data. The work RAM 523 is a memory that temporarily stores work data and flags used when the CPU 521 executes various programs. It is.

  The video RAM 524 is a memory for storing display data to be displayed on the decorative symbol display device 42, and the display content of the decorative symbol display device 42 is changed by rewriting the content of the video RAM 524. The character ROM 525 is a memory that stores character data such as symbols displayed on the decorative symbol display device 42.

  The VDP 526 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal driving circuit) incorporated in the decorative symbol display device 42. Since the VDP 526 is an IC chip, it is also referred to as a “drawing chip”, and the substance of the VDP 526 can be said to be a microcomputer chip with a dedicated firmware for drawing processing. The VDP 526 adjusts the respective timings of the CPU 521, the video RAM 524, etc. to intervene in reading and writing data, and reads the display data stored in the video RAM 524 at a predetermined timing and causes the decorative symbol display device 42 to display it.

  The power supply device 313 includes a power supply unit 541 that supplies power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And. The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in AC 24 volt power supplied from the outside, generates + 12V power for driving various switches and motors, + 5V power for logic, backup power for RAM backup, etc. These + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 261, the payout control device 311 and the like. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute the power failure process (NMI interrupt processing in FIG. 28).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

  The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  Next, the operation of the pachinko machine 10 configured as described above will be described.

  In the present embodiment, the CPU 501 in the main control device 261 performs lottery (big hit lottery) using various counter information in the game. Specifically, as shown in FIG. 24, the jackpot random number counter C1 as a lottery random number counter used for the jackpot lottery and the mode determination used for determining the transition to the high probability mode or the low probability mode described later when the jackpot is won. The counter C2, the fluctuation selection counter C3 used for determining the fluctuation display time of the special display device 39, the initial value random number counter CINI used for setting the initial value of the jackpot random number counter C1, and the fluctuation display time of the special display device 39 Fluctuation type counters CS1 and CS2 used for determination of the normal symbol and the normal symbol random number counter C4 used for the lottery of the normal symbol display device 38 are used. Note that the variation selection counter C3 is also used for a variation pattern and reach type lottery when the decorative symbol display device 42 is deviated and varied. The variation type counters CS1 and CS2 are also used for variation pattern selection (effect pattern selection) of the decorative symbol display device 42. Specifically, the variation time of the special display device 39 is determined by the determined variation pattern, and the variation mode and variation time in the decorative symbol display device 42, that is, the effect pattern (effect mode) are determined.

  Each of the counters C1, C2, C3, CINI, CS1, CS2, and C4 is a loop counter that adds 1 to the previous value every time it is updated and returns to the lower limit value of 0 after reaching the upper limit value. Each counter is periodically updated, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503 (except for the random number initial value counter CINI).

  The RAM 503 is provided with a first reserved ball storage area and a second reserved ball storage area as a storage area composed of one execution area and four reserved areas (first to fourth reserved areas). In each area of the first reserved ball storage area, the values of the jackpot random number counter C1, the mode determination counter C2, and the variation selection counter C3 are time-sequentially matched to the winning history of the game balls to the first opportunity corresponding unit 33. It is designed to be stored. In addition, in each area of the second reserved ball storage area, the value of the normal symbol random number counter C4 is stored in time series in accordance with the passing history of the game ball to the second opportunity corresponding port 34. Yes.

  In detail, each jackpot random number counter C1 is incremented one by one within a range of 0 to 676, for example, and after reaching an upper limit value (ie, 676) as a closing price, 0 is a lower limit value as a starting price. It is the composition which returns to. Normally, when the jackpot random number counter C1 makes one round, the value of the initial value random number counter CINI at that time is read as the next initial value of the jackpot random number counter C1. The initial value random number counter CINI is a loop counter similar to the big hit random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. On the other hand, the jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and the value of the jackpot random number counter C1 is stored in the jackpot random number counter buffer. Then, the value of the jackpot random number counter C1 stored in the jackpot random number counter buffer is stored in the first reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding unit 33. There are two types of jackpot random numbers, a low probability state (normal mode, time reduction mode, etc.) and a high probability state (high probability mode). The number of random number values to be 2 is “337, 673”, the number of random number values that are jackpots in the high probability state is 10, and the value is “67, 131, 199, 269,337,401,463,523,601,661 ".

  Here, various game modes will be described. In the present embodiment, the game mode (game state) is switched between a normal mode (normal state) and a plurality of specific modes that are more advantageous to the player than the normal mode. More specifically, as the specific mode, two modes, a high probability mode and a time reduction mode, are set. Among these, the high probability mode is a game mode that continues until the next jackpot, and the time reduction mode is a mode that shifts to the next mode after the predetermined period.

  The normal mode refers to a normal state that is not a specific mode such as the high probability mode. Therefore, in the normal mode, the jackpot probability (winning probability of the jackpot state) is a normal low probability.

  In addition, the high probability mode is a big win when the special display device 39 is stopped and displayed with “red” (the decorative design display device 42 is stopped and displayed with a predetermined probability variation symbol), and the subsequent big win A state in which the probability is higher than that in the low probability state. In the following description, the case where the decorative symbol display device 42 is a jackpot due to the probability variation symbol is referred to as “probability variation jackpot”, and the case where the jackpot is due to a normal symbol other than the probability variation symbol is referred to as “normal jackpot”.

  In the high probability mode, the jackpot probability is increased and a high probability state is obtained. In addition, in this embodiment, (1) a state in which the variable display time in the special display device 39 is shortened (time shortening state). (2) a state in which the variable display time in the normal symbol display device 38 is shortened, (3) a state in which the specified time (opening time) related to the opening / closing process of the first trigger corresponding unit 33 is longer than that in the normal mode, or A state in which the prescribed number (winning number) is increased compared to the normal mode, and (4) the first opportunity to be performed once when a winning result indicating that the “○” symbol is stopped and displayed on the normal symbol display device 38 is obtained. The number of executions of the opening / closing process of the corresponding unit 33 is larger than that in the normal mode, and (5) the probability that the symbol “○” is stopped and displayed on the normal symbol display device 38 (winning probability) High state than winning probability of time is granted. More specifically, in the high probability mode, the opening / closing member 33a of the first opportunity corresponding unit 33 is in an open state, and when a specified time (for example, 3 seconds) elapses or a specified number (for example, 3) of game balls enter. Closed when there is a ball. This opening / closing process is repeated twice. As a result, the first opportunity corresponding unit 33 is opened frequently, and lottery lotteries are continuously made, and the ball is in good condition. In addition to this, as a high probability mode, in addition to increasing the jackpot probability (winning probability of the jackpot state), any combination of the above configurations (1) to (5) (for example, (1), (2), (3), (4), (5), (1) and (2), (1) and (3), (1) and (4), (1) and (5), (2) and (3 ), (2) and (4), (2) and (5), (3) and (4), (3) and (5), (4) and (5), (1) and (2) (3), (1) and (2) and (4), (1) and (2) and (5), (1) and (3) and (4), (1) and (3) and (5 ), (1) and (4) and (5), (2) and (3) and (4), (2) and (3) and (5), (2) and (4) and (5), (3), (4) and (5), (1), (2), (3) and (4), (1), (2), (3) and (5), (1) and (2 ) And (4) (5) can be employed (1) and (3) and (4) (5), and (2) and (3) and (4) (5)). In addition, the ratio of the open state with respect to the closed state per unit time in the 1st opportunity corresponding | compatible unit 33 will be in a state higher than the ratio in the normal mode by the state of said (2)-(5). That is, such a state corresponds to the high ball entering state in the present embodiment. Therefore, the high probability mode can be paraphrased as a high probability, a time reduction, and a high pitching mode. On the other hand, a state that is not in the states (2) to (5) as in the normal mode corresponds to a low entry state.

  In addition, the time reduction mode is a big hit when the special display device 39 is stopped and displayed in “green” (the decorative symbol display device 42 is stopped and displayed with a normal symbol other than a predetermined probability variation symbol). Thereafter, the game mode is set while the variable display of the special display device 39 is performed 100 times, which means a state more advantageous to the player than the normal mode. The time reduction mode is a gaming mode in which the jackpot probability is the same low probability as in the normal mode, and the ratio of the open state to the closed state per unit time in the first opportunity corresponding unit 33 is higher than the ratio in the normal mode. . In the present embodiment, the states (1) to (5) given in the high probability mode are given in the same manner. That is, except for the difference in jackpot probability (winning probability in the jackpot state), the same state (time shortening state and high pitching state) is obtained. Of course, as in the high probability mode, any combination of the configurations (1) to (5) can be adopted. Therefore, the time shortening mode can be restated as a low probability / time shortening / high pitching mode.

  For example, the mode determination counter C2 is incremented one by one within a range of 0 to 9, for example, and after reaching the upper limit value (that is, 9), the mode determination counter C2 returns to the lower limit value of 0. In the present embodiment, the mode determination counter C2 determines whether or not to shift to the high probability mode after the big hit. Specifically, if the counter value is an odd number such as “1, 3, 5, 7, 9”, the transition to the high probability mode is determined, and if the counter value is an even number such as “0, 2, 4, 6, 8”. In this case, the transition to the time reduction mode is determined. Although the term “transition” is used here, the high probability mode is continued if the counter value is odd when originally in the high probability mode, and the counter value is even when originally in the time reduction mode. If so, the time shortening mode is continued. The mode determination counter C2 is updated periodically (once every timer interruption in this embodiment), and the value of the mode determination counter C2 is stored in the mode determination counter buffer. The value of the mode determination counter C2 stored in the mode determination counter buffer is stored in the first reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding unit 33.

  Further, the variation selection counter C3 is configured so that, for example, one by one is added in order within a range of 0 to 238, for example, and after reaching the upper limit value (that is, 238), it returns to 0 that is the lower limit value. In this embodiment, after the reach is generated with respect to the decorative symbol by the variation selection counter C3, the final stop symbol is shifted by one by one before and after the reach symbol and stopped, and the last stop after the occurrence of reach is also performed. “Reach other than front / rear detachment” where the symbol stops other than before and after the reach symbol and “completely disengagement” where reach does not occur are selected by lottery. For example, C3 = 0, 1 corresponds to front / rear outreach and C3 = 2 to 21 correspond to reach other than front / rear disengagement, and C3 = 22 to 238 corresponds to complete disengagement. The reach lottery may be individually set according to the state of the lottery probability, the number of starting reserved balls at the start of change, and the like. The fluctuation selection counter C3 is updated periodically (once every timer interruption in this embodiment), and the value of the fluctuation selection counter C3 is stored in the fluctuation selection counter buffer. Then, at the timing when the game ball wins the first opportunity corresponding unit 33, the value of the variation selection counter C3 stored in the variation selection counter buffer is stored in the first reserved ball storage area of the RAM 503.

  In addition, one of the two variation type counters CS1 and CS2 is incremented one by one within a range of 0 to 198, for example, and reaches the upper limit value (that is, 198), and then reaches the lower limit value. The other variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the upper limit value (that is, 240) and then returns to the lower limit value of 0. It has become. In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”. This is also shown in FIG. The first variation type counter CS1 determines the reach type (reach pattern) of the decorative symbol such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final after the reach occurrence. A more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the stop symbol (in this embodiment, the middle symbol) stops is determined. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode in combination by combining the first variation type counter CS1 and the stop symbol.

  In the present embodiment, when “big hit” occurs, one of normal reach, super reach, and premium reach is selected, and when “out-of-front reach” occurs, normal reach and super reach are selected. When either one is selected and “reach other than front / rear out” occurs, normal reach is selected. In addition, in the case of “completely off”, none of normal reach, super reach, and premium reach is selected.

  Further, the variation type counters CS1 and CS2 are updated once every time a normal process described later is executed once, and are repeatedly updated even within the remaining time of the normal process. Then, the buffer values of CS1 and CS2 are acquired when determining the variation pattern at the start of variation of the decorative symbol by the decorative symbol display device 42.

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, it is desirable that the big hit random number counter C1, the variation selection counter C3, and the variation type counters CS1 and CS2 are different prime numbers and are not synchronized in any case.

  Further, the normal symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and reaches the upper limit value (that is, 250) and then returns to the lower limit value of 0. The normal symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and the value of the normal symbol random number counter C4 is acquired when the game ball passes through the left or right second opportunity corresponding port 34. Is done. Normally, there are 149 random numbers to be won, and the range is “5 to 153”. On the other hand, in the high probability mode and the time reduction mode, that is, in the case where the first opportunity corresponding unit 33 is in the high pitching state, there are 224, and the range is “5-228”. That is, the probability of stopping the symbol “◯” in the normal symbol display device 38 is higher than that in the normal mode. Then, when the value of the normal symbol random number counter C4 to be won is acquired, after the variable display is performed on the normal symbol display device 38 for a predetermined time, the symbol corresponding to the winning (in this example, “◯”) is stopped and displayed. Then, the first opportunity corresponding unit 33 is activated for a predetermined time. Further, in the high probability mode and the time reduction mode, the time until the lottery result is displayed on the normal symbol display device 38 (variable display time of the normal symbol) is shortened. The ratio at which the unit 33 is in a high entrance state increases. As a result, the first opportunity corresponding unit 33 is frequently opened, and the big hit lottery is continuously performed.

  Next, each control process executed by the CPU 501 in the main controller 261 will be described with reference to a flowchart. The processing of the CPU 501 is broadly divided into a main process that is started when the power is turned on, a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 msec), and a stop signal to the NMI terminal (non-maskable terminal). For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 27 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main control device 261 every 2 msec, for example.

  In FIG. 27, first, in step S301, reading processing of various winning switches is executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  In step S302, random number initial value update processing is executed. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in the present embodiment).

  In step S303, random number update processing is executed. Specifically, the jackpot random number counter C1, the mode determination counter C2, the variation selection counter C3, and the normal symbol random number counter C4 are each incremented by 1 and their counter values are the maximum values (in this embodiment, 676, 9 respectively. , 238, 250) is cleared to 0 respectively. Then, the updated values of the counters C1, C2, C3, and C4 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S304, a start winning process associated with winning the first opportunity corresponding unit 33 is executed, and in step S305, a second opportunity corresponding port passing process accompanying the passing of the game ball to the second opportunity corresponding port 34 is performed. Run. Thereafter, the timer interrupt process is temporarily terminated.

  Here, the start winning process in step S304 will be described with reference to the flowchart of FIG. In step S501, whether or not the game ball has won the first opportunity corresponding unit 33 is determined based on the detection information of the first opportunity corresponding unit switch 224. If it is determined that the game ball has won the first opportunity corresponding unit 33, in the subsequent step S502, it is determined whether or not the number N of starting reserved balls is less than the upper limit value (4 in the present embodiment). The process proceeds to step S503 on condition that there is a winning in the first opportunity corresponding unit 33 and the number N of starting reserved balls is smaller than 4, and the number N of starting reserved balls is incremented.

  In subsequent step S504, a random number related to the success or failure is acquired. Specifically, the values of the jackpot random number counter C1, the mode determination counter C2, and the variation selection counter C3 updated by the random number update process in step S303 are used as the first free storage area in the first reserved ball storage area of the RAM 503. Store in the area. Thereafter, the start winning process is temporarily terminated. Therefore, a part of the lottery means (win / no lottery process) in the present embodiment is configured by the function of the start winning process.

  Next, the second opportunity corresponding port passing process of step S305 will be described with reference to the flowchart of FIG. In step S601, whether or not the game ball has passed through the second opportunity corresponding port 34 is determined based on the detection information of the second opportunity corresponding port switch 225. When it is determined that the game ball has passed through the second opportunity corresponding port 34, in the subsequent step S602, it is determined whether or not the number N of retained balls of the normal symbol display device 38 is less than the upper limit (4 in the present embodiment). Determine. The process proceeds to step S603 on the condition that there is a passage to the second opportunity corresponding port 34 and the number of reserved balls N <4, and the number of reserved balls N is incremented by one. In subsequent step S604, a random number related to the success or failure is acquired. Specifically, the value of the normal symbol random number counter C4 updated by the random number update process in step S303 is stored in the first area of the free storage area of the second reserved ball storage area of the RAM 503. Thereafter, the second opportunity corresponding port passing process is temporarily ended.

  FIG. 28 is a flowchart showing the NMI interrupt process, and this process is executed by the CPU 501 of the main control device 261 when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503.

  That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 261. Then, the CPU 501 interrupts the control being executed and starts the NMI interrupt process. In step S401, the CPU 501 stores the power interruption occurrence information in the backup area 503a of the RAM 503 as the setting of the power interruption occurrence information, and performs the NMI interruption process. finish.

  The above NMI interrupt processing is executed in the same manner in the payout control device 311, and information on occurrence of power interruption is stored in the backup area 513 a of the RAM 513 by the NMI interrupt. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process in FIG. 28 is started. The contents are as described above.

  Next, the flow of main processing executed by the CPU 501 in the main controller 261 will be described with reference to the flowchart of FIG. This main process is started upon reset when power is turned on.

  First, in step S101, an initial setting process associated with power-on is executed. Specifically, for example, 1 is set in order to set a predetermined value in the stack pointer and wait for the sub-side control device (sub-control device 262, payout control device 311, etc.) to become operable. Wait processing is performed for about 2 seconds. In the subsequent step S103, RAM access is permitted.

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, in step S104, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON), and if it is pressed, the process proceeds to step S113 to clear (erase) the backup data. To do. On the other hand, if the RAM erase switch 323 has not been pressed, it is determined in the subsequent step S105 whether power-off occurrence information is set in the backup area 503a of the RAM 503. Here, if it is not set, no backup data is stored. In this case as well, the process proceeds to step S113. If power failure occurrence information is set in the backup area 503a, a RAM determination value is calculated in step S106, and in the subsequent step S107, whether or not the RAM determination value matches the RAM determination value stored when the power is turned off. That is, the effectiveness of the backup is determined. If the RAM determination value calculated here does not match the RAM determination value stored when the power is turned off, the backed up data is destroyed, and the process also proceeds to step S113 in this case.

  In the process of step S113, an initialization command is transmitted in order to initialize the sub control device 262, the payout control device 311 and the like that are the sub-side control devices. Thereafter, the process proceeds to a RAM initialization process (step S114, etc.). Note that the RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Instead of the RAM determination value, it is possible to determine the effectiveness of backup based on whether or not the keyword written in a predetermined area of the RAM 503 is correctly stored.

  As described above, the pachinko machine 10 is turned on while pressing the RAM erase switch 323 when it is desired to return to the initial state when the power is turned on, for example, when the hall starts business. Therefore, if the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S114, etc.). Similarly, when the information on occurrence of power interruption is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 503 (step S114 or the like). That is, in step S114, the used area of the RAM 503 is cleared to 0, and in the subsequent step S115, the initial value of the RAM 503 is set. Thereafter, interrupt permission is set in step S112, and the routine proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed (step S104: NO), it is a condition that the information on occurrence of power interruption is set and that the RAM judgment value (checksum value etc.) is normal. In addition, the process at the time of power recovery (process at the time of power failure recovery) is executed. That is, in step S108, the stack pointer before the power interruption is restored, and in step S109, the information on the occurrence of the power interruption is cleared. In step S110, a command for returning the control device on the sub side to the gaming state at the time of power-off is transmitted, and in step S111, the used register is returned from the backup area 503a of the RAM 503. Thereafter, interrupt permission is set in step S112, and the routine proceeds to normal processing described later.

  Next, the flow of normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As its outline, the processing of steps S201 to S210 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S211 and S212 is executed with the remaining time.

  First, in step S201, a control signal based on the setting contents of the special display device 39 and the first opportunity corresponding unit 33 updated in the previous process is transmitted to each device, and output data such as a command is transmitted to each sub-side. External output processing to be transmitted to the control device is executed.

  For example, when the decorative symbol display device 42 displays the variation of the decorative symbol, a variation pattern command, a symbol command, or the like is transmitted to the sub-control device 262. That is, the variation pattern command and the symbol command are commands (command information) output to the sub-control device 262 in order to cause the decorative symbol display device 42 to perform a display effect in accordance with the display performed on the special display device 39. is there. Therefore, the function of this external output process constitutes the command information output means in this embodiment. On the other hand, the sub-control device 262 that has input the variation pattern command, the symbol command, etc. determines the variation mode of the decorative symbol display device 42 based on the various commands, and displays the variation mode on the decorative symbol display device 42. An instruction is issued to the display control device 45 so as to (variable display).

  For convenience, the variation pattern command and the like will be described here. The variation pattern command includes information for specifying the variation type of the decorative symbol such as normal reach, super reach, and premium reach. In the present embodiment, for example, in the normal mode, any one of “FF10”, “FF11”, “FF12”, “FF13”, “FF14”, “FF15”, and “FF16” is set as the variation pattern command. In the high probability mode, “FD10”, “FD11”, “FD12”, “FD13”, “FD14”, “FD15”, “FD16” are set, and in the time reduction mode, “FE10”, “FE11”. , “FE12”, “FE13”, “FE14”, “FE15”, “FE16” are set. On the other hand, the sub-control device 262 stores the relationship between these variation pattern commands and the variation types of decorative symbols in a table (see FIG. 46). Then, the sub control device 262 executes the effect pattern corresponding to the variation pattern command.

  Hereinafter, the variation type of the decorative symbol and the correspondence between the variation type and the variation pattern command will be described.

  Normal reach is a reach pattern that does not display any special effects other than the variation of the decorative design. In the variation pattern command corresponding to the normal reach, “FF11” is set in the normal mode, “FD11” is set in the high probability mode, and “FE11” is set in the time reduction mode. In this embodiment, the variable display time for which the normal reach is derived is set to “20 seconds” in the normal mode, “8 seconds” in the high probability mode, and “10 seconds” in the time reduction mode.

  Super Reach is a reach pattern in which characters and the like are displayed on the decorative symbol display device 42 in addition to the decorative symbol during the variation display of the decorative symbol (after the reach state is established), thereby giving the player a sense of expectation. is there. In this embodiment, three types (super reach SR1, SR2, SR3) of 30 second, 40 second, and 50 second patterns are prepared for the super reach in the normal mode. Note that the variable display time in the high probability mode and in the time reduction mode is shortened compared to that in the normal mode, as in the normal reach. Corresponding to each reach pattern, in the case of the super reach SR1, “FF12” in the normal mode, “FD12” in the high probability mode, and “FE12” in the time reduction mode are set as the variation pattern commands. In the case of the super reach SR2, “FF13” in the normal mode, “FD13” in the high probability mode, and “FE13” in the time reduction mode are set. In the case of the super reach SR3, “FF14” in the normal mode, “FD14” in the high probability mode, and “FE14” in the time reduction mode are set.

  Premium reach is an effect that can be derived only when a big hit state occurs. During the decorative symbol variation display (after reaching the reach state), in addition to the decorative symbol, a character with a different pattern from the super reach is displayed. This is a reach pattern that makes the player have a sense of expectation. In the premium reach of this embodiment, two types (premium reach PR1, PR2) of 60-second and 70-second patterns are prepared in the normal mode. Note that the variable display time in the high probability mode and in the time reduction mode is shortened compared to that in the normal mode, as in the normal reach. Corresponding to each reach pattern, in the premium reach PR1, “FF15” in the normal mode, “FD15” in the high probability mode, and “FE15” in the time reduction mode are set as the variation pattern command. In the premium reach PR2, “FF16” in the normal mode, “FD16” in the high probability mode, and “FE16” in the time reduction mode are set.

  In addition, the fluctuation pattern command corresponding to “complete out” that does not reach any reach state is set to “FF10” in the normal mode, “FD10” in the high probability mode, and “FE10” in the time reduction mode. The In the present embodiment, the variable display time that is completely off is set to 10 seconds in the normal mode. Of course, the variable display time in the high probability mode and the time shortening mode is shortened compared to the normal mode as in the normal reach.

  Further, the sub-control device 262 determines a stop symbol (combination of stop symbols) based on the symbol command, and displays it after the fluctuation time has elapsed. The symbol command is a command for causing the sub-control device 262 to determine a stop symbol, a combination of probability variation symbols, a normal symbol combination, a front / rear off symbol combination, a front / rear off symbol combination, a complete out symbol design combination. Five classifications are designated, which are the combinations. These divisions are indicated by “A1”, “A2”, “A3”, “A4”, “A5”, and any of these is set as a symbol command. On the other hand, the sub-control device 262 stores the relationship between these commands and stop symbols in a table. Then, the sub control device 262 displays a stop symbol corresponding to the symbol command.

  Hereinafter, the stop symbol classification and the correspondence between the stop symbol and the symbol command will be described.

  The combination of probability variation symbols is a combination of symbols composed of numbers 1, 3, 5, 7, and 9 and “A1” is set in the symbol command corresponding to the combination of probability variation symbols. Then, when “A1” indicating the probability variation symbol is set in the symbol command, the sub-control device 262 is one of the combinations of symbols consisting of the numbers 1, 3, 5, 7, and 9 in the form of a slot. Is determined as a stop symbol.

  The combination of normal symbols is a combination of symbols consisting of numbers 0, 2, 4, 6 and 8, and “A2” is set in the symbol command corresponding to the combination of normal symbols. Then, when “A2” indicating the normal symbol is set in the symbol command, the sub-control device 262 is one of the combinations of symbols consisting of the numbers 0, 2, 4, 6, and 8. Is determined as a stop symbol.

  The combination of back and forth symbols corresponds to the combination of back and forth symbols, where after reaching, the final stop symbol is stopped by one shift before and after the reach symbol. “A3” is set in the symbol command. The combination of symbols other than front / rear detachment corresponds to the “reach other than front / rear detachment” that occurs after reach occurs, and the final stop symbol stops other than before / after the reach symbol. “A4” is set in the command. The combination of complete detachment symbols corresponds to “complete detachment” in which no reach occurs, and “A5” is set in the symbol command corresponding to the combination of complete detachment symbols. As will be described in detail later, when “A3” to “A5” are set in the symbol command, the sub-control device 262 stops the combination of symbols stored in the counter buffer of the corresponding RAM 553. Determine as. In the present embodiment, three commands “A3” to “A5” are prepared for the symbol command for detachment. However, the present invention is not limited to this. For example, a configuration having only one symbol command for detachment may be used.

  Returning to FIG. 26, in step S202, update of the variation type counters CS1 and CS2 is executed. More specifically, like the other counters, the variation type counters CS1 and CS2 are incremented by 1 and cleared to 0 when the counter values reach the upper limit values (198 and 240 in this embodiment). To do. Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503.

  In the subsequent step S203, the prize ball counting signal received from the payout control device 311 is read. Next, in step S204, the payout abnormality signal received from the payout control device 311 is read.

  Thereafter, in step S205, a first display control process is executed. In this process, the control content of the special display device 39 is set as to what kind of control is performed in the special display device 39, and the jackpot determination and the decorative pattern variation pattern (effect pattern) in the decorative symbol display device 42 are performed. Settings are made. Details of the first display control process will be described later. The decorative pattern variation pattern (effect pattern) corresponds to a display effect effect mode in the present embodiment.

  In step S206, variable winning device control processing is executed. In this process, the control content of the variable winning device 32 is set as to what control is performed in the variable winning device 32. As a result, when the big win state (special game state) is reached, the opening / closing process of the big winning opening of the variable winning device 32 is repeatedly executed for a predetermined number of rounds. Details of the variable winning device control process will be described later. The special game state control means in this embodiment is configured by the function of the variable winning device control process.

  In step S207, the second display control process is executed. In this processing, the control contents of the normal symbol display device 38 are set as to what kind of control is performed in the normal symbol display device 38. Details of the second display control process will be described later.

  In step S208, an opportunity handling unit control process is executed. In this process, the control content of the first opportunity handling unit 33 is set as to what control is performed in the first opportunity handling unit 33.

  After that, in step S209, it is determined whether or not occurrence information of power interruption is set in the backup area 503a of the RAM 503. Here, if the occurrence information of power interruption is not set in the backup area 503a, it is determined in step S210 whether or not the next normal processing execution timing has been reached, that is, a predetermined time from the start of the previous normal processing (this embodiment) It is determined whether or not 4 msec) has elapsed. And if predetermined time has already passed, it will transfer to Step S201 and will repeat the processing after the above-mentioned Step S201.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal process, the random number initial value counter CINI and the variation type counters CS1 and CS2 are updated within the remaining time until the execution timing of the next normal process. Repeatedly execute (step S211, step S212).

  That is, in step S211, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in the present embodiment).

  In step S212, the variation type counters CS1 and CS2 are updated (similar to step S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the change values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S201 to S209 changes according to the state of the game, the remaining time until the next execution timing of the normal process is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time, and similarly change The type counters CS1 and CS2 can also be updated at random.

  Now, if the occurrence information of power interruption is set in the backup area 503a of the RAM 503 (step S209: YES), the power is cut off, so that the processing after step S213 is performed as a power failure process at the time of power interruption. Is called. In the power failure process, first, the generation of each interrupt process is prohibited in step S213, the contents of each register used by the CPU 501 are saved in the stack area in step S214, and the value of the stack pointer is saved in the backup area 503a in step S215. To remember. Thereafter, in step S216, a power-off notification command indicating that the power has been cut off is transmitted to other control devices (such as the payout control device 311). In step S217, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Thereafter, RAM access is prohibited in step S218, and the infinite loop is continued until the power supply is completely shut down and processing cannot be executed.

  The process of step S209 is performed at the end of a series of processes corresponding to the game state change performed at steps S201 to S208, or at the end of one cycle of the processes of steps S211 and S212 performed within the remaining time. It is executed at the timing. Therefore, in the normal process of the main controller 261, the occurrence information of the power interruption is confirmed at the end of each process, so that the amount of data stored in the backup area 503a of the RAM 503 is less than that in the middle of each process. And can be easily memorized. Further, when returning to the state before power-off, since the amount of data stored in the backup area 503a is small, it can be easily restored and the processing load of the main control device 261 can be reduced. . Further, since the interruption processing is prohibited before the data is stored (step S213), it is possible to prevent the data from being changed when the power is shut off and to reliably store the state before the power is shut off. .

  Next, the first display control process of step S205 will be described with reference to the flowchart of FIG.

  In FIG. 31, in step S801, it is determined whether or not a big hit is currently being made. The jackpot includes a jackpot state (special game state) and a predetermined time after the jackpot state ends.

  In the subsequent step S802, it is determined whether or not color change display (variable display) is being performed by the special display device 39 by looking at the setting state of the display timer. Specifically, when the display timer is set (when it is in the on state), it is regarded as a variable display, and when the display timer is released (when it is in the off state), the variable display is in a stopped state. It is considered that the stop display is in progress. If it is not a big hit and is not being displayed in a variable manner, the process proceeds to step S803, where it is determined whether or not the number N of starting reserved balls is greater than zero. At this time, if it is a big hit or if the number N of starting reserved balls is 0, this processing is terminated as it is.

  Further, if neither the big hit or the variable display is being displayed and if the number of starting reserved balls N> 0, the process proceeds to step S804. In step S804, 1 is subtracted from the number N of starting reserved balls. In step S805, processing for shifting the data stored in the first reserved ball storage area is executed. This data shift process is a process for sequentially shifting the data stored in the first to fourth areas on hold in the first holding ball storage area to the execution area side. Data in each area is shifted, such as area → holding first area, holding third area → holding second area, holding fourth area → holding third area.

  Thereafter, in step S806, a variable display setting process is executed. Here, the details of the variable display setting process will be described with reference to the flowchart of FIG.

  First, in step S901, it is determined whether or not a big hit is made based on the value of the big hit random number counter C1 stored in the execution area of the first reserved ball storage area. Specifically, whether or not the jackpot is determined is determined based on the relationship between the value of the jackpot random number counter C1 and the mode at that time, and the numerical value 0 to 676 of the jackpot random number counter C1 in the low probability state such as the normal mode as described above. Among them, “337, 673” is a winning value, and in the high probability mode, “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” is a winning value. Therefore, a part of the lottery means (win / fail lottery process) in the present embodiment is configured by the function of this process. If it is determined that the game is a big hit (step S901: YES), the process proceeds to step S902. On the other hand, when it is determined that it is not a big hit (step S901: NO), that is, when it is out of place, the process proceeds to step S909.

  In step S902, it is determined whether or not the probability variation jackpot. In the present embodiment, the system is configured to shift to the high probability mode or the time reduction mode with a probability of 1/2 in the case of a big hit. Specifically, whether or not to shift to the high probability mode is determined based on the value of the mode determination counter C2 stored in the execution area of the first reserved ball storage area. If the value of the stored mode determination counter C2 is an odd number “1, 3, 5, 7, 9” among the numerical values 0 to 9, the transition to the high probability mode is determined (probability large hit), and the even number “ If it is 0, 2, 4, 6, 8 ", the transition to the time reduction mode is determined (usually a big hit).

  Here, when it is determined that the probability variation jackpot (step S902: YES), the jackpot variation pattern is determined in step S904, and the probability variation symbol (“A1” in the present embodiment) is set to the symbol command in step S905. Then, the process proceeds to step S917.

  On the other hand, if it is determined in step S902 that it is not a probable big hit (step S902: NO), that is, if it is a normal big hit, a big hit variation pattern is determined in step S907, and a normal symbol (this embodiment) is determined in step S908. Then, “A2”) is set as the symbol command, and the process proceeds to step S917.

  In steps S904 and S907, the variation pattern at the time of the big hit is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the symbol variation mode of the decorative symbol is determined based on the values of the first and second variation type counters CS1 and CS2. . The relationship between the numerical value of the first variation type counter CS1 and the reach pattern (variation type) and the relationship between the numerical value of the second variation type counter CS2 and the variation time are defined in advance by a table or the like for each game mode. . Note that the mode determination in the present embodiment is performed by a combination of an on / off state of a high probability state flag, a time shortening state flag, and a high entry state flag, which will be described later. For example, if the high probability state flag, the time shortening state flag, and the high pitched state flag are all on (flag value “1”), it is determined that the mode is a high probability mode.

  Here, the correspondence between the numerical values of the first variation type counter CS1 and the second variation type counter CS2 and the variation type will be described. For example, at the big hit in the normal mode, the correspondence is defined by a normal mode big hit table as shown in FIG. That is, when CS1 = 0 to 9, “FF11” (normal reach) is set in the variation pattern command regardless of the value of CS2. When CS1 = 10 to 196 and CS2 = 0 to 69, “FF12” (super reach SR1) is set in the variation pattern command. When CS1 = 10 to 196 and CS2 = 70 to 149, “FF13” (super reach SR2) is set in the variation pattern command. When CS1 = 10 to 196 and CS2 = 150 to 240, “FF14” (super reach SR3) is set in the variation pattern command. When CS1 = 197, 198 and CS2 = 0-120, “FF15” (premium reach PR1) is set in the variation pattern command. When CS1 = 197, 198 and CS2 = 121-240, “FF16” (premium reach PR2) is set in the variation pattern command.

  The symbol commands in step S905 and step S908 indicate the jackpot symbol in a predetermined section, and the sub controller 262 determines the stop symbol as will be described later. Specifically, when “A1” indicating the combination of probability variation symbols is set in the symbol command (step S905), the symbol combination of any one of the first, third, fifth, seventh, and ninth slots is sub-selected. The control device 262 determines the stop symbol. On the other hand, when “A2” indicating the combination of normal symbols is set in the symbol command (step S908), any combination of symbols 0, 2, 4, 6, and 8 is changed to the sub-control device 262. Is determined as a stop symbol. After the symbol command is set in step S905 and step S908, the process proceeds to step S917.

  In step S909, which is shifted when a negative determination is made in step S901, it is determined whether or not a reach is reached. This determination is made based on the value of the variation selection counter C3 stored in the execution area of the first reserved ball storage area. As described above, in the present embodiment, the fluctuation selection counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting by one by one before and after the reach symbol, and the final stop after the occurrence of reach. “Reach other than front / rear detachment” where the symbol stops other than before and after the reach symbol and “completely disengagement” where reach does not occur are selected by lottery. For example, C3 = 0, 1 corresponds to front / rear outreach and C3 = 2 to 21 correspond to reach other than front / rear disengagement, and C3 = 22 to 238 corresponds to complete disengagement. Here, when it is determined that it is reach (step S909: YES), the process proceeds to step S910. On the other hand, if it is determined that it is not reach (step S909: NO), that is, if it is “completely out”, a dislocation variation pattern is determined in step S915, and a complete out symbol is set as a symbol command in step S916. Then, the process proceeds to step S917.

  In step S910, it is determined whether or not the front / rear reach is reached. If it is determined that the front / rear reach is out of step (step S910: YES), a deviation variation pattern is determined in step S911, the front / rear pattern is set as a symbol command in step S912, and the process proceeds to step S917. . On the other hand, when it is determined that it is not front / rear detachment (step S910: NO), that is, when it is reach other than front / rear detachment, a detachment variation pattern is determined in step S913, and symbols other than front / rear detachment are determined in step S914. The command is set, and the process proceeds to step S917.

  When the outlier variation pattern is determined in steps S911, S913, and S915, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503. And so on. In addition, the effect determination means in this embodiment is comprised by said step S904, S907, S911, S913, S915.

  Here, the correspondence between the numerical value of the first variation type counter CS1 and the variation type will be described. For example, at the time of front / rear detachment during the normal mode, the correspondence is defined by a table for front / rear detachment during the normal mode as shown in FIG. That is, when CS1 = 0 to 9, “FF11” (normal reach) is set in the variation pattern command regardless of the value of CS2. When CS1 = 10 to 198 and CS2 = 0 to 90, “FF12” (super reach SR1) is set in the variation pattern command. When CS1 = 10 to 198 and CS2 = 91 to 170, “FF13” (super reach SR2) is set in the variation pattern command. When CS1 = 10 to 198 and CS2 = 171 to 240, “FF14” (super reach SR3) is set in the variation pattern command. At the time of reach other than forward / backward deviation (C3 = 2 to 21), the reach is normal regardless of the values of the variation type counters CS1 and CS2, and “FF11” is set in the variation pattern command. Further, at the time of complete deviation (C3 = 22 to 238), “FF10” is set in the variation pattern command regardless of the values of the variation type counters CS1 and CS2.

  Further, the symbol command in step S912, step S914, and step S916 indicates a predetermined division of the combination of symbols that are out of the same manner as in step S905 and the like. Specifically, when “A3” indicating a combination of front and rear symbols is set as a symbol command (step S912), the sub-control device 262 that has received the symbol command stores it in the front and rear error symbol buffer of the RAM 553. The combination of symbols corresponding to the front / rear out of reach is determined as the stop symbol. When “A4” indicating a combination of symbols other than front / rear detachment is set in the symbol command (step S914), a combination of symbols corresponding to reach other than front / rear detachment stored in the reach symbol buffer other than front / rear detachment of RAM 553 is selected. The sub-control device 262 determines the stop symbol. When “A5” indicating the combination of completely out of symbols is set in the symbol command (step S916), the combination of symbols corresponding to the complete out of the symbol stored in the complete out of symbol buffer of the RAM 553 is sub-control unit 262. Is determined as a stop symbol.

  In step S917, a start setting process is performed to indicate that a condition for performing color change display (variation display) is satisfied on the special display device 39. In this start setting process, a display timer setting process is performed. The display timer is a means for measuring the fluctuation time, and is considered when determining whether or not a predetermined time has elapsed since the start of the fluctuation display. For example, when the variation time is 10 seconds (10000 msec), it is set to 10000 msec. As will be described later, the display timer is decremented by 4 msec every time the normal process is performed once. In addition, the value corresponding to the variation pattern of the decorative design selected by the variation type counters CS1 and CS2 is set as the variation display time of the special display device 39 in the present embodiment. Based on such setting of the display timer, when a control signal for starting color change display (variation display) is output to the special display device 39 in the next external output processing of normal processing, the special display is performed. Color change display is started in the device 39. The special display device 39 is a three-color LED as described above, and changes color to green if the lit color is red, blue if it is green, and red if it is blue. Then, after step S917 ends, the variable display setting process ends.

  Returning to the description of FIG. 31, if step S802 is YES, that is, if the variable display is being performed, the process proceeds to step S807 to perform display timer subtraction processing. Each time this process is performed, the value of the display timer is subtracted by 4 msec. For example, when a display timer of 10000 msec is set, the value of the display timer is 9996 msec in the display timer subtraction process in the next normal process for the time when the display timer is set.

  Subsequently, the process proceeds to step S808, and it is determined whether or not a predetermined fluctuation time has elapsed with reference to the value of the display timer after the subtraction. At this time, when a predetermined fluctuation time has elapsed, that is, when the value of the display timer becomes “0”, an affirmative determination is made in step S808. If an affirmative determination is made in step S808, the display timer is canceled [turned off (cleared)] in step S809, and stop display setting for performing a stop display on the special display device 39 is performed in step S810. Then, based on the setting contents of the stop display setting, a control signal for performing stop display is output to the special display device 39 in the next external output process in the normal process. In other words, if it is a promiscuous jackpot with a transition to the high probability mode, the red is stopped (for example, lighted only for a few seconds), and if it is a regular jackpot with a transition to the time reduction mode, the green is stopped and displayed. If it is off, blue is stopped and displayed. Again, such a stop display by the special display device 39 is the main display, and the display of the decorative symbols by the decorative symbol display device 42 is only auxiliary.

  In step S811, discrimination information setting processing is performed. More specifically, as shown in FIG. 33, in step S1001, it is determined whether or not the stop display corresponds to a jackpot. Here, when it corresponds to jackpot, it transfers to step S1002 and performs jackpot setting. Specifically, processing for setting a jackpot flag, a variable flag, a variable timer, and a round number counter is performed. And after completion | finish of step S1002, a discrimination | determination information setting process is complete | finished.

  The jackpot flag is state determination information for determining whether or not the jackpot state is a special gaming state, and here, “1” indicating the occurrence of the jackpot state is set as the flag value. The value of the jackpot flag is determined based on the value of the jackpot random number counter C1.

  The variable flag is determination information for determining whether or not the variable winning device 32 is in an open state.

  The variable timer is means for measuring the opening time of the variable winning device 32, and is considered when determining whether or not a specified time has elapsed since the start of opening.

  The round number counter is discriminating information for discriminating the number of rounds executed during the jackpot state (the number of special prize occurrences, that is, the number of executions of the opening / closing process of the variable winning device 32), as will be described later. “15” indicating 15 rounds is set as a value.

  If it is determined in step S1001 that the jackpot does not correspond, that is, it is determined that the game is out of place, the process proceeds to step S1003.

  In step S1003, it is determined whether or not a variation counter is set. The variation counter is a means for measuring the duration of the time-reduced state (how many variations are displayed). As will be described later, “100” is set as the counter value after the end of the normal jackpot.

  Here, when the variation counter is canceled (in the off state), this processing is terminated as it is. On the other hand, when the variation counter is set (in the ON state), it is regarded that the time reduction state is being set, and in step S1004, the value of the variation counter is decremented by 1, and the process proceeds to step S1005. To do.

  In step S1005, it is determined whether or not the value of the variation counter is zero. That is, it is determined whether or not the current variation display is the 100th variation display after the end of the normal jackpot (after the provision of the time reduction state). Here, if the remaining value of the variation counter is 0 count, a process of resetting a high pitching state flag described later in step S1006 is performed (set to “0”), and a time shortening state flag described later is set in step S1007. A process of resetting (setting “0”) is performed, a process of canceling (turning off) the variation counter is performed in step S1008, and the present process is terminated.

  On the other hand, if it is determined in step S1005 that the value of the variation counter is not 0 count, the present process is terminated.

  Returning to the description of FIG. 31, after the discrimination information setting process in step S811, the first display control process is terminated. If the determination in step S808 is negative, in step S812, the color change display setting for continuously performing the color change display (fluctuation display) of the LED of the special display device 39 is performed, and this process is terminated. To do. Based on the setting contents of the color change display setting, a control signal for performing color change display is output to the special display device 39 in the external output process in the next normal process. Specifically, it is set to change the color to green if the current lighting color is red, blue if it is green, and red if it is blue. Thereby, the color change display (variation display) of the LED of the special display device 39 is realized at the timing of the first display control process, that is, every 4 ms. In the present embodiment, the determination information setting process (step S811) is performed after the stop display setting process (step S810). However, the present invention is not limited to this. For example, the variable display setting process (step S806). It is good also as a structure performed after.

  Next, the variable winning device control process of step S206 will be described with reference to the flowchart of FIG.

  First, in step S1201, it is determined whether or not the variable flag of the variable winning device 32 is on. Here, when it is determined that the variable flag is not ON (OFF), this processing is ended as it is.

  As described above, the variable flag is determination information for determining whether or not the variable winning device 32 is in the open state, and when the variable flag is set in the determination processing of step S1201 ( When the variable flag is released (in the off state), it is regarded as being in the closed state.

  Based on the ON / OFF state of the variable flag, various control signals are output to the variable winning device 32 in the next external output process of the normal process. When the variable flag is ON, a control signal for opening the big prize opening is output to the variable winning device 32, and the variable winning device 32 is opened. On the other hand, when the variable flag is OFF, a control signal is output to the variable winning device 32 to close the big winning opening, and the variable winning device 32 is closed.

  On the other hand, if an affirmative determination is made in step S1201, that is, if the variable flag is on, the variable winning device 32 is considered to be in the open state, and variable timer subtraction processing is performed in step S1202. Each time this process is performed, the value of the variable timer is decremented by 4 msec.

  In step S1203, the value of the variable timer after the subtraction is taken into consideration to determine whether or not the specified open time has elapsed. Here, when the specified opening time has elapsed, that is, when the value of the variable timer becomes “0”, an affirmative determination is made in step S1203. If a positive determination is made in step S1203, the process proceeds to step S1204.

  If a negative determination is made in step S1203, it is determined whether or not the number of game balls won in the variable winning device 32 in step S1205 has reached a specified number. If a positive determination is made here, the process proceeds to step S1204. On the other hand, if a negative determination is made in step S1205, that is, if the number of winnings to the variable winning device 32 has not reached the prescribed number, this processing is terminated as it is. Therefore, the variable winning device 32 maintains the open state until the specified opening time elapses or until the specified number of game balls wins, and becomes the closed state when the condition is satisfied.

  Proceeding to step S1204, it is determined whether or not the number of times the variable winning device 32 has been released, that is, the number of executed rounds has reached a specified number (the value of the round number counter is 0), taking into account the value of the round number counter. . Here, if the number of rounds has not reached the specified number, in step S1206, 1 is subtracted from the value of the round number counter, and this process is terminated as it is. That is, the opening / closing process is repeated until the number of executed rounds reaches a predetermined number of times set in advance.

  On the other hand, if it is determined in step S1204 that the number of rounds has reached the specified number, an end setting process is performed in step S1207, and the process ends.

  In the end setting process of step S1207, the variable flag and variable timer reset process (cancellation process), the jackpot flag reset process, the round number counter reset process, the high probability state flag setting process, and the time reduction state flag setting process Then, a process for setting a high pitching state flag, a process for setting a variation counter, and the like are performed.

  More specifically, the variable flag and the variable timer are released (turned off) by the reset process of the variable flag and the variable timer.

  In the jackpot flag reset process, “0” indicating the end of the jackpot state is set as the flag value.

  The round number counter is canceled (off) by the reset processing of the round number counter.

  The high probability state flag is state determination information for determining whether or not the game mode is a high probability state. In the high probability state flag setting process, the high probability state flag is stored in the execution area of the first reserved ball storage area. The flag value is switched and set based on the value of the current mode determination counter C2. As a result, when the high probability mode is set after the jackpot ends (probability jackpot), “1” indicating the occurrence of a high probability state is set as the flag value, and the time reduction mode is set (normal jackpot) “0” indicating the occurrence of a low probability state is set as the flag value.

  The time reduction state flag is state determination information for determining whether or not the game mode is a time reduction state. In the time reduction state flag setting process, “1” indicating that a time reduction state is generated is set. Set as a flag value.

  The high entry state flag is state determination information for determining whether or not the game mode is a high entry state, and indicates that the high entry state is generated in the high entry state flag setting process. “1” is set as the flag value.

  The variation counter is a means for measuring the duration of the time-reduced state (how many variations are displayed) as described above. In the variation counter setting process, the high probability state flag setting process and Similarly, the change count counter is switched based on the value of the mode determination counter C2. Thus, when the high probability mode is set after the jackpot is finished (probability jackpot), the variation counter is canceled (off). On the other hand, when the time reduction mode is set (usually a big hit), “100” corresponding to 100 fluctuation displays is set as the value of the fluctuation counter.

  Next, the second display control process of step S207 will be described with reference to the flowchart of FIG.

  In FIG. 36, in step S2101, it is determined whether or not switching display (variation display) is being performed by the normal symbol display device 38 by looking at the setting state of the display timer. Specifically, when the display timer is set (when it is in the on state), it is regarded as a variable display, and when the display timer is released (when it is in the off state), the variable display is in a stopped state. It is considered that the stop display is in progress. If it is not in the variable display, the process advances to step S2102 to determine whether or not the number of reserved balls N is greater than zero. At this time, if the number of reserved balls N is 0, this processing is terminated as it is.

  On the other hand, if the variable display is not being performed and the number of held balls N> 0, the process proceeds to step S2103. In step S2103, 1 is subtracted from the number of reserved balls N. In step S2104, a process for shifting the data stored in the second reserved ball storage area is executed. This data shift process is a process for sequentially shifting the data stored in the holding first to fourth areas of the second holding ball storage area to the execution area side. The holding first area → the execution area, the holding second Data in each area is shifted, such as area → holding first area, holding third area → holding second area, holding fourth area → holding third area.

  Thereafter, in step S2105, start setting processing is executed. In this process, the normal symbol display device 38 performs a process indicating that a condition for performing switching display (variation display) is established. Specifically, the display timer setting process of the normal symbol display device 38 is performed. The display timer is a means for measuring the fluctuation time, and is considered when determining whether or not a predetermined time has elapsed since the start of the fluctuation display. It should be noted that the variable display time of the normal symbol display device 38 in the present embodiment is set in advance in each of the high entry state and the low entry state as described above. Based on such setting of the display timer, when a control signal for starting switching display (variation display) is output to the normal symbol display device 38 in the next external output processing of the normal processing, the normal symbol is output. Switching display is started on the display device 38. As described above, the normal symbol display device 38 is configured to illuminate and display “O” or “X” as an ordinary symbol. If the displayed symbol is “O”, “X”, “X” "Is switched to" ○ ". Then, after step S2105 ends, the second display control process ends.

  If step S2101 is YES, that is, if variable display is being performed, the process proceeds to step S2106 to perform display timer subtraction processing. Each time this process is performed, the value of the display timer is subtracted by 4 msec.

  Subsequently, the process proceeds to step S2107, and it is determined whether or not a predetermined fluctuation time has elapsed with reference to the value of the display timer after the subtraction. At this time, when a predetermined fluctuation time has elapsed, that is, when the value of the display timer becomes “0”, an affirmative determination is made in step S2107. If an affirmative determination is made in step S2107, the display timer is released [turned off (cleared)] in step S2108, and a stop display setting for performing stop display on the normal symbol display device 38 is performed in step S2109. Then, based on the setting contents of the stop display setting, a control signal for performing stop display is output to the normal symbol display device 38 in the external output process in the next normal process. That is, in the case of winning, the “◯” symbol (winning symbol) is stopped (for example, lit only for a few seconds), and in the case of being off, the “x” symbol is stopped.

  As described above, it is determined whether or not the winning is made based on the value of the normal symbol random number counter C4 stored in the execution area of the second reserved ball storage area. Specifically, whether or not it is won is determined based on the relationship between the value of the normal symbol random number counter C4 and the mode at that time, and as described above, the numerical value of the normal symbol random number counter C4 in the low entry state such as the normal mode. Of the 0 to 250, “5-153” is the winning value, and “5 to 228” is the winning value in a high pitched state such as the high probability mode.

  Subsequently, the process proceeds to step S2110 to perform discrimination information setting processing, and this processing is terminated. In this process, when the stop display corresponds to winning, a setting process for performing the opening / closing process of the first opportunity handling unit 33 is performed. Specifically, a setting process of a variable flag, a variable timer, and an opening number counter is performed.

  The variable flag is determination information for determining whether or not the first opportunity handling unit 33 is in an open state.

  The variable timer is a means for measuring the opening time of the first opportunity handling unit 33, and is taken into account when determining whether or not a specified time has elapsed since the start of opening.

  The opening number counter is determination information for determining the number of execution times of the opening / closing process of the first opportunity corresponding unit 33.

  On the other hand, if a negative determination is made in step S2107, in step S2111 a switching display setting for continuously performing switching display (fluctuation display) of the normal symbol display device 38 is performed, and this processing is terminated. Then, based on the setting contents of the switching display setting, a control signal for performing switching display is output to the normal symbol display device 38 in the external output processing in the next normal processing. Specifically, if the current lighting is “◯”, “×” is displayed, and if “×”, the display is switched to “◯”. Thereby, the switching display (variable display) of the normal symbol display device 38 is realized at the timing of the second display control process, that is, every 4 ms.

  Next, the opportunity handling unit control processing in step S208 will be described with reference to the flowchart in FIG.

  First, in step S2201, it is determined whether or not the variable flag of the first opportunity handling unit 33 is on. Here, when it is determined that the variable flag is not ON (OFF), this processing is ended as it is.

  As described above, the variable flag is determination information for determining whether or not the first opportunity handling unit 33 is in the open state, and the variable flag is set in the determination process of step S2201. In the case (in the on state), it is regarded as being in the open state, and in the case where the variable flag is released (in the case of the off state), it is regarded as being in the closed state.

  Based on the ON / OFF state of the variable flag, various control signals are output to the first opportunity handling unit 33 in the next external output process of the normal process. When the variable flag is on, a control signal for opening the opening / closing member 33a is output to the first trigger corresponding unit 33, and the first trigger corresponding unit 33 is opened. On the other hand, when the variable flag is off, a control signal for closing the opening / closing member 33a is output to the first trigger corresponding unit 33, and the first trigger corresponding unit 33 is closed.

  On the other hand, if an affirmative determination is made in step S2201, that is, if the variable flag is on, the first trigger handling unit 33 is considered to be in the open state, and variable timer subtraction processing is performed in step S2202. Each time this process is performed, the value of the variable timer is decremented by 4 msec.

  Subsequently, the process proceeds to step S2203, and it is determined whether or not the specified open time has elapsed by taking into account the value of the variable timer after the subtraction. Here, when the specified opening time has elapsed, that is, when the value of the variable timer becomes “0”, an affirmative determination is made in step S2203. If an affirmative determination is made in step S2203, the process advances to step S2204.

  If a negative determination is made in step S2203, it is determined whether or not the number of game balls won in the first opportunity corresponding unit 33 in step S2205 has reached a prescribed number. If an affirmative determination is made here, the process proceeds to step S2204. On the other hand, if a negative determination is made in step S2205, that is, if the number of winnings to the first opportunity handling unit 33 has not reached the specified number, this processing is terminated. Therefore, the first opportunity corresponding unit 33 maintains the open state until the specified opening time elapses or until the specified number of game balls wins, and becomes the closed state when the above condition is satisfied.

  Proceeding to step S2204, it is determined whether or not the number of times of opening of the first opportunity handling unit 33 has reached a specified number by considering the value of the number of times of opening counter (the value of the number of opening counter is 0). If the number of times of opening has not reached the specified number of times, 1 is subtracted from the value of the number of times of opening counter in step S2206, and this process is terminated. That is, the opening / closing process is repeatedly performed until a predetermined number of times set in advance is reached.

  On the other hand, if it is determined in step S2204 that the number of times of opening has reached the specified number of times, an end setting process is performed in step S2207, and this process ends.

  In the end setting process in step S2207, the variable flag and variable timer reset process (release process), the release number counter reset process, and the like are performed.

  More specifically, the variable flag and the variable timer are released (turned off) by the reset process of the variable flag and the variable timer. Further, the release number counter is released (turned off) by the reset process of the release number counter.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. For convenience of explanation, the reception interrupt process will be described first with reference to FIG. 38, and then the main process will be described with reference to FIG.

  FIG. 38 is a flowchart showing a reception interrupt process executed by the payout control apparatus 311. The reception interrupt process is a process executed by interruption when the payout control device 311 receives a command transmitted from the main control device 261. When the payout control device 311 confirms that the command transmitted from the main control device 261 has been received, the other processing executed by the CPU 511 in the payout control device 311 is temporarily waited, and the reception interrupt process is executed. When the reception interrupt process is executed, the command transmitted from the main control device 261 in step S3001 is first stored in the command buffer of the RAM 513, and the command transmitted from the main control device 261 is stored in step S3002. Turns on the command reception flag and ends this reception interrupt processing. As described above, when a command is stored in the command buffer, the storage pointer is referred to and stored in a predetermined storage area, and the storage pointer is stored in order to store the next received command in the next storage area. Is updated.

  In the present embodiment, the reception process of the command transmitted from the main control device 261 is performed by the interrupt process executed when the command is received. For example, as illustrated in FIG. In the timer interrupt process, before the command determination process (step S3201) is performed, it is confirmed whether or not a command is received. If a command is received, the command is stored in the command buffer of the RAM 513. The command reception flag may be turned on, and if no command is received, the process may proceed to command determination processing. In such a case, it is confirmed whether or not a command has been received by confirming a port corresponding to the command input of the input / output port at predetermined intervals.

  Next, main processing of the payout control apparatus 311 will be described with reference to FIG. FIG. 39 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

  First, in step S3101, an initial setting process associated with power-on is executed. Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. In step S3103, the RAM access is permitted, and in step S3104, an external interrupt vector is set.

  Thereafter, in step S3106, it is determined whether or not occurrence information of power interruption is set in the backup area 513a of the RAM 513. If the information on occurrence of power interruption is set in the backup area 513a, a RAM determination value is calculated in step S3107, and in step S3108, whether the RAM determination value matches the RAM determination value stored when the power is turned off. No, that is, the validity of the backup is determined. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. Note that it is possible to determine the validity of the backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If no power-off occurrence information is set in step S3106, or if a backup abnormality is confirmed by a RAM determination value (checksum value or the like) in step S3108, the process proceeds to initialization processing of the RAM 513 after step S3115. Transition.

  In step S3115, the entire area of the RAM 513 is cleared to 0, and in step S3116, the initial value of the RAM 513 is set. Thereafter, in step S3117, the CPU peripheral device is initialized, and the process proceeds to step S3114 to permit interruption.

  On the other hand, on the condition that the power failure occurrence information is set in step S3106 and the RAM judgment value (checksum value etc.) is normal in step S3108, the process at the time of power recovery (at the time of power failure recovery) Process). That is, in step S3109, the stack pointer before power-off is restored, power-off occurrence information is cleared in step S3110, and a payout permission flag that permits payout of prize balls is cleared in step S3111. In step S3112, the CPU peripheral device is initialized. In step S3113, the used register is restored from the backup area 513a of the RAM 513. In step S3114, an interrupt is permitted.

  After the interruption is permitted in step S3114, it is determined in the process of step S3122 whether power-off occurrence information is set in the backup area 513a. Here, if the information on occurrence of power supply interruption is set, the power supply is cut off. Therefore, the processing after step S3123 is performed as a power failure process at the time of power supply interruption. In the power failure process, first, the generation of each interrupt process is prohibited in step S3123, and a command determination process described later is executed in the next step S3124. Thereafter, the contents of each register used by the CPU 511 are saved in the stack area in step S3125, the stack pointer value is stored in the backup area 513a in step S3126, and the RAM determination value is calculated in step S3127 to calculate the backup area 513a. In step S3128, RAM access is prohibited, and the infinite loop is continued until the power supply is completely shut down and processing cannot be executed. Here, the RAM determination value is, for example, a checksum value in the stack area and work area to be backed up in the RAM 513.

  Note that since the process of step S3122 confirms the occurrence information of the power-off after the process performed at the time of turning on the power, the amount of data stored in the backup area 513a of the RAM 513 is smaller than that in the middle of each process. Less and can be easily memorized. Further, when returning to the state before power-off, since the amount of data stored in the backup area 513a is small, it can be easily restored and the processing load of the payout control device 311 can be reduced. .

  Next, timer interrupt processing of the payout control device 311 will be described with reference to the flowchart of FIG. This timer interrupt process is started periodically (in this embodiment, at a cycle of 2 msec).

  In the timer interrupt process, first, a command from the main control device 261 is acquired, and a determination process for the command is performed (step S3201). This command determination process will be described below with reference to FIG.

  FIG. 41 is a flowchart showing command determination processing performed by the payout control device 311. In the command determination process (steps S3124 and S3201), first, it is determined whether or not the command reception flag is turned on in step S3301. The command reception flag is turned on when a command transmitted from the main controller 261 is received in the above-described reception interrupt process (see FIG. 38).

  If it is determined in step S3301 that the command reception flag is OFF, a new command has not been received from the main control device 261, and thus this process is terminated. On the other hand, if it is determined in step S3301 that the command reception flag is on, the received command is read from the RAM 513 in step S3302, and the command reception flag is turned off in step S3303. By turning off the command reception flag in step S3303, the processing in steps S3302 to S3311 can be skipped until a new command is received, so that the control of the payout control device 311 can be reduced.

  The type of command read from the RAM 513 is determined in the processing of step S3304 to step S3306. In step S3304, it is determined whether or not the command transmitted from the main control device 261 is a payout initialization command. In step S3305, it is determined whether or not it is a payout return command. In step S3306, it is determined whether the command is a prize ball command. It is determined whether or not.

  If the command transmitted from the main controller 261 is a payout initialization command, it is determined in step S3307 whether or not the payout permission flag has already been turned on. If the payout permission flag has been turned off, the main power is turned on. Since the initialization of the RAM 513 is instructed from the control device 261, the work area (area) other than the stack area of the RAM 513 is cleared to 0 in step S3308, and the initial value of the RAM 513 is set in step S3309. Thereafter, in step S3311, the payout permission flag is turned on, and the payout permission for the winning ball is set.

  As described above, the main controller 261 performs initialization processing of the RAM 503 after transmitting the payout initialization command, and the payout control device 311 initializes processing of the RAM 513 after receiving the payout initialization command. Therefore, the timing at which the RAM 503 is initialized and the timing at which the RAM 513 is initialized are substantially at the same time. Therefore, even if the payout control device 311 receives a command transmitted from the main control device 261 due to a shift in the initialization timing, the RAM 513 is initialized, and control corresponding to the received command cannot be performed. The occurrence of adverse effects can be prevented. In addition, since the payout permission flag is turned on after the RAM 513 is initialized, it is possible to reliably set the payout allowance for prize balls.

  On the other hand, if the payout permission flag has already been turned on in step S3307, the command determination process is terminated without clearing the work area of the RAM 513 and the initialization process of the RAM 513. That is, the processing in step S3307 prohibits initialization of the RAM 513 with the payout permission flag set. The payout initialization command is a command that is transmitted only when the RAM erase switch 323 is turned on when the power is turned on. Therefore, the payout initialization command is not received in a state where the payout permission flag is turned on. It is conceivable that the payout control device 311 has recognized the payout initialization command due to the influence of noise or the like. Therefore, if the work area of the RAM 513 is cleared (step S3308) and the initial value setting of the RAM 513 (step S3309) is executed in a state where the payout permission flag is turned on, the payout is not made when a prize ball remains. Although an adverse effect occurs and causes a loss to the player, since the RAM 513 is prevented from being initialized while the payout permission flag is turned on, it is possible to prevent the player from being lost.

  Further, if the command transmitted from the main control device 261 is a payout return command (step S3304: NO, step S3305: YES), the main control device 261 and the payout control device 311 return to the state before the power cut-off. In order to permit the payout of the prize ball, the payout permission flag is turned on in step S3311. That is, when there is information on occurrence of power interruption and the main control device 261 and the payout control device 311 return to the state before the power interruption, the payout of the prize ball is permitted. When the payout permission flag is turned on in the process of step S3311, the process based on the command stored in the predetermined storage area of the command buffer is completed, so the read pointer is changed to the read pointer corresponding to the next storage area. Updated.

  Further, if the command transmitted from main controller 261 is a prize ball command (step S3305: NO, step S3306: YES), the received prize ball number is added to the total prize ball number and stored in step S3310. In order to permit the payout of prize balls, the payout permission flag is turned on in step S3311. At this time, the payout control device 311 sequentially reads out the prize ball commands stored in the command buffer (ring buffer), and adds the number of prize balls corresponding to the command to the total number of prize balls stored in a predetermined buffer area. And remember. Since a prize ball corresponding to the number of prize balls is paid out based on the prize ball command transmitted from the main controller 261, the prize ball command is a payout instruction command for instructing the prize ball to be paid out. . In addition, when a winning ball command is received, the payout permission is immediately set, so that the winning ball can be paid out early for winning. When the payout permission flag is turned on in the process of step S3311, the process based on the command stored in the predetermined storage area of the command buffer is completed, so the read pointer is changed to the read pointer corresponding to the next storage area. Updated.

  Note that the command transmitted from the main controller 261 is not a payout initialization command (step S3304: NO), is not a payout return command (step S3305: NO), and is not a prize ball command (step S3306: NO), The command determination process is terminated without turning on the payout permission flag.

  Returning to the flowchart of FIG. When the command determination process ends, it is determined in step S3202 whether or not the payout permission flag is turned on in the command determination process. Here, if the payout permission flag is not turned on, this processing is ended as it is. That is, it is possible to prevent award balls from being paid out before a command is transmitted from the main controller 261.

  On the other hand, if an affirmative determination is made in step S3202, the launch permission is set for the launch control device 312 in step S3203, and the state return switch 321 is checked in step S3204, and the state return operation is determined to be started. Perform a return operation. With this process, when the state return switch 321 is pressed when a payout error occurs, for example, when the payout motor is clogged, the payout motor is rotated forward and reverse to eliminate the ball clogging (return to the normal state). .

  Thereafter, in step S3205, setting of the lower plate full state or the lower plate full state is performed according to the change in the state of the lower plate 15. That is, when the lower pan 15 is detected based on the detection signal of the lower pan full switch, when the lower pan is full, the lower pan full state is set, and when the lower pan full is not reached , Set the lower pan full release state. In step S3206, setting of a tank ball absence state (out of ball state) or a tank ball absence release state (ball state) is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and the special setting for the absence of the tank ball and the setting for the no tank ball state are executed. Perform configuration.

  Thereafter, in step S3207, for example, the presence / absence of a state to be notified, such as an error state, is determined.

  Subsequently, a payout control process for prize balls and rental balls is executed. Specifically, a payout number setting process is performed in step S3208, a motor control state acquisition process is performed in step S3209, and a motor drive process is performed in step S3210.

  In step S3211, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In a succeeding step S3212, the control of the vibrator 360 (vibration motor control) is executed on condition that the ball is clogged. Thereafter, the process returns to the beginning of the timer interrupt process.

  Next, processing of the sub control device 262 will be described. The sub-control device 262 that has input the variation pattern command, the symbol command, etc. determines the display mode of the decorative symbol display device 42 based on the various commands, and the display mode is transferred to the display control device 45 in the decorative symbol display device 42. Display. Similarly, control of the shutter accessory 43, the annular illumination part 102, etc. is performed.

  Here, the normal processing of the sub-control device 262 will be described in more detail with reference to the flowchart of FIG. This normal process is started periodically (in this embodiment, at a cycle of 4 msec).

  First, in step S3901, external output processing for transmitting a control signal based on the setting content updated in the previous processing to each device is executed. For example, a display command is transmitted to the display control device 45 or a control signal is transmitted to the shutter accessory 43 when the decorative symbol display device 42 displays the variation of the decorative symbol.

  In step S3902, various counter update processes are executed. The CPU 551 of the sub-control device 262 uses various counter information when displaying decorative symbols. Specifically, as shown in FIG. 43, the jackpot decorative symbol counter C5 and the upper, middle and lower outlier counters CL, CM, used for setting the outlier symbols in the upper row, middle row and lower row, CR is used. The off symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 551, and as a result, the numerical values change randomly.

  The jackpot decorative symbol counter C5 determines the symbol when the variation of the decorative symbol display device 42 stops when the jackpot is hit (the jackpot symbol). In the present embodiment, the decorative symbol display device 42 determines the decorative symbol. There are 5 patterns and 5 normal symbols. Accordingly, five (0 to 4) counter values are prepared as the big hit decoration symbol counter C5. That is, the jackpot decoration symbol counter C5 is incremented by 1 in order within the range of 0 to 4, and reaches 0 to the upper limit value (that is, 4). When the symbol command transmitted from the main control device 261 is “A1” indicating a combination of probability variation symbols, for example, based on a table (a table that associates counter values with decorative symbols), the counter value is If it is 0, it is “1”. ) If it is 4, the combination of probability variation symbols is determined in such a manner as “9” (the flat eye). When the symbol command is “A2” indicating a combination of normal symbols, for example, if the counter value is 0, “0” (based on a table (not shown) that associates the counter value with the decorative symbol) ( 1) “2” (for the doublet), 2 for “4” (for the doublet), 3 for “6” (for the doublet), 4 for “8” ”(The doublet) and the normal symbol combination is determined. The jackpot decorative symbol counter C5 is periodically updated in the counter update process in step S3902, and is read from the counter buffer of the RAM 553 at the timing when the sub-control device 262 receives the symbol command as will be described later. In this embodiment, the jackpot decorative symbol counter C5 is stored in the jackpot decorative symbol counter buffer of the RAM 553, but is not stored in the buffer, and the counter value is referred to at the timing of receiving the symbol command. It may be.

  The upper, middle and lower off symbol counters CL, CM, CR determine the stop symbol (combination of the off symbol) of the upper row ornament symbol, middle row ornament symbol, and lower row ornament symbol when the big hit lottery is missed. Since each of 10 decorative symbols is displayed in each column, 10 (0 to 9) counter values are prepared for each column. The stop symbol of the upper symbol row is determined by the off symbol counter CL, the stop symbol of the middle symbol row is determined by the off symbol counter CM, and the stop symbol of the lower symbol row is determined by the off symbol counter CR.

  In the present embodiment, the values of the counters CL, CM, and CR are randomly updated by using the value of the R register built in the CPU 551. That is, when each outlier symbol counter CL, CM, CR is updated, the value of the lower 3 bits of the R register is added to the previous value, and when the addition result exceeds the upper limit value, 10 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the front / rear outreach symbol buffer of RAM 553, the reach symbol buffer other than front / rear out, and It is stored in one of the completely off symbol buffers.

  Here, the update process of each off symbol counter CL, CM, CR will be described in detail. As shown in FIG. 44, in step S4001, it is determined whether or not it is time to update the out symbol counter CL of the upper symbol row, and in step S4002, it is determined whether or not it is time to update the out symbol counter CM in the middle symbol row. . It should be noted that each outlier symbol counter CL, CM, CR of the upper symbol row, the middle symbol row, and the lower symbol row is configured to be updated one by one in one update process. Therefore, if the out symbol counter CR in the lower symbol row has been updated in the previous update process, an affirmative determination is made in step S4001. If the out symbol counter CL in the upper symbol row has been updated in the previous update process, an affirmative determination is made in step S4002. If the upper symbol sequence is updated (YES in step S4001), the process advances to step S4003 to update the out symbol symbol CL of the upper symbol sequence. If the middle symbol row update time (step S4002 is YES), the process proceeds to step S4004, and the middle symbol row outlier symbol counter CM is updated. Further, if the lower symbol sequence is updated (NO in steps S4001 and S4002), the process proceeds to step S4005, and the out symbol counter CR of the lower symbol sequence is updated. In updating the outlier symbol counters CL, CM, and CR in steps S4003 to S4005, the lower 3 bits of the R register are added to the previous counter value, and 10 is subtracted when the addition result exceeds the upper limit value. The calculation result is set as the current value of the off symbol counters CL, CM, CR.

  According to the above-described CL, CM, and CR update processing, the off symbol counters CL, CM, and CR of the upper symbol row, the middle symbol row, and the lower symbol row are updated one by one in a single update process. The update times of the values do not overlap. As a result, every time the update process is executed three times, the set symbol counters CL, CM, and CR are updated for one set.

  Thereafter, in step S4006, it is determined whether or not the combination of the updated out symbol counters CL, CM, and CR is a reach symbol combination, and if it is a reach symbol combination (YES in S4006), Further, in step S4007, it is determined whether or not it is a front-rear reach. If the out symbol counters CL, CM, CR are a combination of front / rear out of reach (front / rear out symbol) (YES in S4007), the process proceeds to step S4008, and the combination of the out symbol counters CL, CM, CR at that time is stored in the RAM 553. Is stored in the front / rear reach reach symbol buffer. If the out symbol counters CL, CM, CR are a combination of reach other than front / rear disengagement (design other than front / back disengagement) (NO in S4007), the process proceeds to step S4009, and the out symbol counters CL, CM, CR at that time The combination is stored in the reach symbol buffer other than the front and rear deviation of the RAM 553.

  If the combination is other than the reach symbol (NO in S4006), the process proceeds to step S4010 to determine whether or not the combination of the symbol symbols CL, CM, and CR is out of the combination, and the symbol is separated. If it is a combination of symbols (completely deviated symbols) (YES in S4010), the process proceeds to step S4011, and the combination of deviated symbol counters CL, CM, CR at that time is stored in the completely deviated symbol buffer of the RAM 553. If NO in both steps S4006 and S4010, the symbols are aligned at the top, middle, and bottom, that is, it corresponds to a combination of jackpot symbols. In this case, the off symbol counters CL, CM, CR are used as buffers. This process is terminated without storing.

  Returning to the description of FIG. 42, in step S3903, it is determined whether or not the command transmitted from the main controller 261 has been received. In this case, by confirming the port corresponding to the command input of the input / output port 554, it is confirmed whether or not the command is received. If a command has been received, the command is stored in the command buffer of the RAM 553 in step S3904. On the other hand, if no command has been received, the process proceeds to step S3905.

  The command buffer of the RAM 553 is a ring buffer that temporarily stores commands transmitted from the main control device 261. The ring buffer has a predetermined storage area, and commands are stored with regularity from the beginning to the end of the storage area. When commands are stored in all storage areas, the ring buffer is at the start of the storage area. The return command is configured to be updated. Therefore, when the command is stored and when the command is read, the storage pointer and the read pointer in the command buffer are updated, and the command is stored and read based on each pointer.

  When a command is received from the main control device 261, various setting processes according to the command are performed.

  In the effect setting process of step S3905, for example, based on information stored in the command buffer of the RAM 553, various arithmetic processes such as generating a display command to be output to the display control device 45 and command output setting are performed. Accordingly, the display mode to be displayed on the decorative symbol display device 42 is determined here, and a value corresponding to the variation time of the variation pattern command is set in the variation time measurement timer. At this time, the sub-control device 262 performs processing based on a table associating, for example, the decorative symbol variation type and variation pattern command as shown in FIG.

  The display command is, for example, a command for designating a series of display effects from the start to the end of variable display, or a command for designating a display effect during a jackpot, based on information stored in the command buffer. Each time a necessary display command is generated.

  Here, the stop symbol is also determined based on the symbol command. As described above, when “A1” is set in the symbol command, any combination of symbols 1, 3, 5, 7, and 9 is determined as a stop symbol. On the other hand, when “A2” is set in the symbol command, a combination of symbols 0, 2, 4, 6, and 8 is determined as a stop symbol. When “A3” is set in the symbol command, the combination of symbols stored in the front / rear reach reach symbol buffer (see FIG. 43) of the RAM 553 is determined as a stop symbol. When “A4” is set in the symbol command, the combination of symbols stored in the reach symbol buffer other than front / rear deviation is determined as a stop symbol. When “A5” is set in the symbol command, the combination of symbols stored in the completely off symbol buffer is determined as a stop symbol.

  Then, a display command to be output to the display control device 45 is generated based on these pieces of information. Usually, the display commands related to the variable display generated by the sub-control device 262 are roughly divided into a normal variable data group, a reach effect data group, and the like. Basically, each data constituting these data groups is the variable time timer. Are sequentially output in accordance with a predetermined time order, thereby providing display effects according to various variation patterns. For example, the normal fluctuation data group includes normal fluctuation data 1, normal fluctuation data 2,..., And normal fluctuation data m, and the reach effect data group includes reach effect data 1, reach effect data 2,. In the case of n, data output is sequentially performed in the order of normal fluctuation data 1 → 2 →... → m with the start of normal fluctuation, and subsequently reach effect data 1 → 2 → with the start of reach effect. ... → Data is sequentially output in the order of n.

  In the subsequent shutter setting process in step S3906, a setting process for driving and controlling the shutter accessory 43 is performed. For example, the shutter accessory 43 operates when a specific reach effect is performed on the decorative symbol display device 42.

  Here, the shutter setting process will be described in detail with reference to the flowchart of FIG.

  In step S4101, it is determined whether or not the shutter accessory 43 is activated. If a determination result indicating that the shutter accessory 43 is to be operated is obtained, that is, if a specific reach effect is performed, the process proceeds to step S4102. On the other hand, when a determination result indicating that the shutter accessory 43 is not operated is obtained, the present process is terminated.

  In step S4102, the operation pattern of the shutter piece set 715 is determined in accordance with the effect pattern (effect mode) of the decorative symbol display device 42. In the present embodiment, a plurality of operation patterns of the shutter piece set 715 are set. For example, a totally closed pattern (see FIG. 22) in which the display unit 42a of the decorative symbol display device 42 is invisible is set, a four-divided pattern (see FIG. 19) in which the display unit 42a is divided into four, etc. Yes. These operation patterns are stored in advance in a table as input patterns of drive pulses to the step motor of the motor unit 785. Therefore, when determining a predetermined operation pattern corresponding to the effect pattern of the decorative symbol display device 42, an operation pattern table corresponding to the predetermined operation pattern is extracted and stored in the table storage area of the RAM 553. .

  In step S4103, the rotational position of the ring member 720 is detected. The rotation position of the ring member 720 is detected by monitoring whether or not a detection signal is received from the photosensors 795a to 795c and confirming whether or not the light shielding portion 797 of the ring member 720 has been detected. By detecting the rotation position of the ring member 720, it is possible to grasp what state the shutter piece set 715 is in. For example, when the light shielding portion 797 of the ring member 720 is detected by the photosensor 795c, it can be determined that the ring member 720 is at the reference position and the shutter piece set 715 is in the fully open state (see FIG. 17). Further, when the light shielding portion 797 of the ring member 720 is detected by the photosensor 795a, it can be determined that the shutter piece set 715 is in the fully closed state (see FIG. 22).

  In the present embodiment, since the operation control of the shutter piece set 715 is performed based on the operation pattern table, by monitoring the number of drive pulses input to the step motor as long as the reference position is known in advance, The drive amount (position) of the shutter piece set 715 can be grasped and the drive control can be performed such as stopping the shutter piece set 715 in a predetermined state. However, some trouble occurs and the actual rotation position of the ring member 720 When the sub-control device 262 grasps the position grasped, the position can be corrected based on the detection signals from the photosensors 795a to 795c. For example, in the present embodiment, the photo sensor 795b is provided, and the stage immediately before the shutter piece set 715 is completely closed can be detected. Therefore, the shutter piece set 715 can be decelerated and collision with other members can be avoided. .

  In step S4104, based on the contents of the operation pattern table of the shutter piece set 715 set in step S4102, the drive pulses are sequentially output to the step motor in accordance with a time sequence determined in advance based on the variable time timer. Set up to do. Thereafter, this process is terminated.

  Based on this drive pulse output setting process, the shutter pulse 43 is operated according to the effect pattern of the decorative symbol display device 42 by sequentially outputting drive pulses to the step motor in the external output process of step S3901.

  Returning to the description of FIG. 42, in the following step S3907, control settings for driving voices and lamps are performed, and this process is terminated. The sub-control device 262 performs control settings for driving sounds and lamps, such as lamp lighting patterns and sound output patterns, in synchronization with display effects at each time.

  Then, the display control device 45 performs a drawing process in response to a command from the sub-control device 262, and starts a variable display of symbols on the decorative symbol display device. Once the variation pattern command is received from main controller 261, sub-control is performed until the variation time corresponding to the variation pattern has elapsed (until the variation time timer set in step S3905 becomes 0). Under the cooperation of the device 262 and the display control device 45, the variable display of symbols is continued. When the shutter accessory 43 operates, the shutter accessory 43 also operates in accordance with the change display.

  Then, when the main control device 261 determines the jackpot, the special display device 39 displays that effect, and the decorative symbol is supplementarily combined with the jackpot symbol on the decorative symbol display device 42, so that the special game video as the jackpot Is displayed (a jackpot is started).

  Here, the display mode of the decorative symbol display device (liquid crystal display device) 42 will be described in more detail. As shown in FIG. 47, the display unit 42a of the decorative symbol display device 42 is set with three upper, middle, and lower symbol columns (identification information columns), and a plurality of types of symbols (decoration) for each symbol column. The symbol is variably displayed. In the present embodiment, as shown in FIG. 48, symbols Z0 to Z9 are set as decorative symbols. The symbols Z0 to Z9 are configured to be given numbers “0” to “9”, respectively. The symbols Z0 to Z9 are scrolled and displayed from right to left with a periodicity in ascending or descending numerical order, thereby forming a series of symbol strings. Note that the symbol variation mode is not limited to scroll variation, and may be switching variation or the like.

  In this case, in the upper symbol row, symbols Z0 to Z9 are displayed in descending order (in the order in which the attached numbers decrease), and in the middle symbol row and lower symbol row, the symbols Z0 to Z9 are also in ascending order (numbers attached). (In order of increasing)). Then, after the predetermined time has elapsed, the variable display stops in the order of the upper symbol row → the lower symbol row → the middle symbol row, and at the time of the stop, the symbols Z0 to Z9 are combined with the jackpot symbol on the predetermined jackpot line (in this embodiment) If a combination of symbols of the same type), the jackpot video is displayed as a jackpot.

  In addition, immediately before the combination of jackpot symbols described above is displayed, a so-called reach state (a state where the reach mode is established) is obtained. However, even if it reaches a reach state, it may not reach a big hit state.

  In this embodiment, the jackpot line is composed of left, middle and right vertical lines and two diagonal lines (referred to as five lines). Therefore, in the upper, middle, and lower symbol rows, when the same type of symbols Z0 to Z9 is stopped and displayed side by side on any of the five lines (for example, “ When three "1" symbols Z1 are stopped and displayed), a big hit state occurs.

  In addition, the reach state in the present embodiment includes a state in which the symbol variation of the lower symbol row stops at the same kind of symbols as the stop symbol of the upper symbol row on the jackpot line. For example, in FIG. 49, in each of the upper and lower symbol rows, the symbol Z1 of “1” is stopped and displayed on the diagonally descending big hit line on the right side, and “9” is displayed on the diagonally descending big hit line on the left side. The case where symbol Z9 is stopped and displayed and the middle symbol row is still changing is illustrated. In this case, if the symbol Z1 or the symbol Z9 is stopped and displayed on the jackpot line in the middle symbol row, a jackpot state occurs. In addition, in the reach state, the symbols in the middle symbol row are not the same as the symbols in the upper and lower symbol rows that eventually stop at the same symbol type (big hit symbol) and become a big hit state. Stopping at a symbol (this is called “outgoing reach design”) and not being a big hit state (this is called “outgoing reach state”) are included. In FIG. 49, symbols Z0 to Z9 displayed in the middle symbol row are omitted for convenience. In the reach state, various reach effects are performed as described above.

  As described above in detail, in the present embodiment, even if the first link mechanism and the second link mechanism are provided, the motor unit 785 as a drive source and the ring member 720 as a power transmission member have only one configuration. The different operation modes such as the integral rotational displacement operation of the shutter piece set 715 (shutter pieces 731 to 734) and the relative displacement operation of the shutter piece set 715 (shutter pieces 731 to 734) are multistage without interfering with each other. Can be performed automatically. Further, the movement of one ring member 720 in the same direction causes the four shutter piece sets 715 to perform the same operation, and performs different operations such as the integral rotation displacement operation and the relative displacement operation continuously and smoothly. It can be carried out. As a result, there is no need to provide a plurality of drive sources and power transmission members corresponding to a plurality of shutter pieces (shielding members), and the parts of the drive mechanism of the shutter accessory 43 that shields the display portion 42a of the decorative symbol display device 42. An increase in the number of points can be suppressed.

  In addition, the second to fourth shutter pieces 732 to 734 are configured such that the third shutter piece 733 and the second shutter piece 732 move in accordance with the movement of the fourth shutter piece 734 by mutual engagement. . Accordingly, for example, the third shutter piece 733 and the second shutter piece 732 are driven while moving more members with one drive source and the power transmission member and shielding the display portion 42a of the decorative symbol display device 42. Compared to a configuration in which a third link mechanism or the like is separately provided, the complexity of the drive mechanism of the shutter accessory 43 can be suppressed.

  Furthermore, by providing a plurality of shutter piece sets 715, the shutter pieces 43 are dispersed, and the number of shutter pieces in each shutter piece set 715 is reduced as much as possible, so that the shutter accessory 43 can be thinned.

  In addition, the angle α of the tip of each first shutter piece 731 viewed from the front of the shutter accessory 43 is 90 °, and the tip of each first shutter piece 731 of the four shutter piece sets 715 is the shutter role. When the center portion of the window 43a of the object 43 is substantially in contact, the vicinity of the center of the window 43a is shielded with almost no gap. Further, the fourth shutter piece 734 and thus the second shutter piece with the axis centered near the center of the display part 42a of the decorative symbol display device 42 by the biaxial rotation operation by the first shutter piece 731 and the fourth shutter piece 734. 732 and the third shutter piece 733 can be rotated. As a result, a single shutter piece (shielding member) is individually arranged at a plurality of locations around the display unit 42a of the decorative symbol display device 42, and these are protruded toward the display unit 42a as necessary. Compared to a configuration that shields 42a, the entire display unit 42a can be shielded more reliably with almost no gap.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above-described embodiment, the annular shutter accessory 43 is illustrated as an example of the shutter accessory that shields the display unit 42a of the decorative symbol display device 42. May be adopted.

  For example, a shutter accessory 900 as shown in FIGS. 50 to 54 may be used. The shutter accessory 900 is provided at a position above the display unit 42 a of the decorative symbol display device 42.

  The shutter accessory 900 includes a set of shutter pieces 901 as a shielding member set, a slide member 902 as a power transmission member for driving them, and a motor unit 903 as a power source.

  The motor unit 903 includes a step motor and a gear mechanism that transmits the driving force of the motor to the slide member 902. In FIGS. 50 to 54, only the gear mechanism is shown for the sake of convenience. Further, in FIG. 50 and the like, a dotted pattern is given to the portion of the shutter piece set 901 for easy understanding of the operation of the shutter piece set 901.

  The shutter piece set 901 is composed of five shutter pieces as shielding members. More specifically, a first shutter piece 901a pivotally supported on a casing as a base frame (not shown), a second shutter piece 901b assembled so as to be relatively displaceable with respect to the first shutter piece 901a, 3 shutter pieces 901c, a fourth shutter piece 901d, and a fifth shutter piece 901e. Each of the shutter pieces 901a to 901e is formed in a substantially rectangular flat plate shape. In the present embodiment, the first shutter piece 901a corresponds to the first shielding member, the fifth shutter piece 901e corresponds to the second shielding member, and the second shutter piece 901b to the fourth shutter piece 901d serve as the third shielding member. Equivalent to.

  The shutter piece set 901 is assembled so that the shutter pieces 901a to 901e are overlapped in the front-rear direction. In normal times, the second to fifth shutter pieces 901b to 901e are on the back side of the first shutter piece 901a. (See FIG. 50).

  In the first shutter piece 901a, a rotating shaft portion 905 that is pivotally supported with respect to the casing (the front side in the drawing) is formed in the vicinity of a predetermined corner portion so as to protrude forward.

  On the other hand, the second to fifth shutter pieces 901b to 901e are slidably provided. Each of the shutter pieces 901a to 901e is provided with an engaging means for engaging with the adjacent shutter pieces. By these engagements, relative displacement of a predetermined amount or more between both adjacent shutter pieces is restricted, and the other can be operated by following (moving) one movement.

  The first shutter piece 901a is formed with a first engagement shaft portion 907 that protrudes rearward. The first engagement shaft portion 907 is loosely fitted in a first cam groove 909 described later formed in the slide member 902.

  The fifth shutter piece 901e is formed with a second engagement shaft portion 908 protruding rearward. The second engagement shaft portion 908 is loosely fitted in a second cam groove 910 described later formed in the slide member 902.

  Next, the slide member 902 for driving the shutter piece set 901 will be described in detail. The slite member 902 is formed in an elongated shape, and drives the shutter piece set 901 by a sliding operation along the horizontal direction.

  A first cam groove 909 and a second cam groove 910 are provided on the surface portion of the slide member 902.

  One end of the first engagement shaft portion 907 of the first shutter piece 901a is inserted into the first cam groove 909. One end of the second engagement shaft portion 908 of the fifth shutter piece 901e is inserted into the second cam groove 910.

  The first link mechanism configured by the first cam groove 909 and the first engagement shaft portion 907 is to integrally rotate and displace the shutter piece set 901 (shutter pieces 901a to 901e) around the rotation shaft portion 905. Mechanism. Therefore, in the present embodiment, the first cam groove 909 corresponds to the first cam portion, and the first engagement shaft portion 907 corresponds to the first acted portion.

  On the other hand, the second link mechanism constituted by the second cam groove 910 and the second engagement shaft portion 908 is configured such that the fifth shutter piece 901e and thus the second to fourth shutter pieces 901b to 901d are relative to the first shutter piece 901a. It is a mechanism for sliding displacement. Therefore, in the present embodiment, the second cam groove 910 corresponds to the second cam portion, and the second engagement shaft portion 908 corresponds to the second operated portion.

  Similarly to the above-described embodiment, the first cam groove 909 has an action section (an action section at the time of set rotation displacement) that acts on the first engagement shaft portion 907 when the shutter piece set 901 is integrally rotated and displaced. The fifth shutter piece 901e has a non-interference section (non-interference section at the time of relative displacement) that does not interfere with the first engagement shaft portion 907 (the power of the slide member 902 is not transmitted) when the fifth shutter piece 901e is relatively displaced.

  The second cam groove 910 has an action section (action section at the time of relative displacement) that acts on the second engagement shaft portion 908 when the fifth shutter piece 901e is relatively slid and displaced, and the shutter piece set 901 is integrally rotated and displaced. A non-interference section (non-interference section at the time of set rotation displacement) that does not interfere with the second engagement shaft portion 908 (the power of the slide member 902 is not transmitted).

  A gear portion 913 is formed on the upper side portion of the slide member 902 and meshes with the gear mechanism of the motor unit 903.

  Next, the operation of the shutter piece set 901 will be described. Normally, the shutter piece set 901 is held above the display portion 42a of the decorative symbol display device 42 in a state where the first to fifth shutter pieces 901a to 901e are overlapped (see FIG. 50). This state corresponds to the normal state (reference state) of the shutter piece set 901, and the display unit 42a of the decorative symbol display device 42 is fully opened.

  From this state, when the slide member 902 is slid leftward by the motor unit 903, the first engagement shaft portion 907 of the first shutter piece 901a located near the upper side of the slide member 902 is moved to the first cam. While being pushed leftward by the action section of the groove 909, it gradually moves to the lower side of the slide member 902 (see FIG. 51). As a result, the shutter piece set 901 (shutter pieces 901a to 901e) is integrally rotated and displaced in the counterclockwise direction around the rotation shaft portion 905, and jumps out to the front of the display portion 42a of the decorative symbol display device 42. It will be.

  At this time, the second engagement shaft portion 908 of the fifth shutter piece 901e moves along the non-interference section of the second cam groove 910 so as not to interfere with the rotation operation of the shutter piece set 901.

  When the slide member 902 slides by a predetermined amount, the tip of the shutter piece set 901 faces downward, and the shutter piece set 901 is in a substantially vertical state (see FIG. 52).

  In this state, the first engagement shaft portion 907 of the first shutter piece 901a moves to the non-interference section of the first cam groove 909, and the second engagement shaft portion 908 of the fifth shutter piece 901e The cam groove 910 moves to the operating section.

  From this point, when the slide member 902 continues to move leftward, the second engagement shaft portion 908 of the fifth shutter piece 901e is pushed leftward by the action section of the second cam groove 910. Then, the fifth shutter piece 901e is pulled out from the back side of the first shutter piece 901a while the first shutter piece 901a is held in the vertical state (see FIG. 53).

  When the slide member 902 continues to move in the left direction, the fourth shutter piece 901d is pulled out from the back side of the first shutter piece 901a so as to be pulled by the fifth shutter piece 901e, and is pulled by the fourth shutter piece 901d. In this way, the third shutter piece 901c is pulled out, and the second shutter piece 901b is pulled out so as to be pulled by the third shutter piece 901c (see FIG. 54). If it will be in this state, the display part 42a of the decoration symbol display apparatus 42 will be in a fully closed state.

  When the shutter piece set 901 returns to the original state, the procedure reverse to the above procedure is followed.

  (B) In the above-described embodiment, the four shutter piece sets 715 are provided. However, the present invention is not limited to this. For example, only one set may be provided. In this case, if the number of driven shutter pieces such as the second and third shutter pieces 732 and 733 in the above embodiment is increased, the entire display portion 42a of the decorative symbol display device 42 can be shielded with almost no gap. . However, if the number of shutter pieces overlapping each other in one set of shutter pieces increases, the thickness of the shutter piece set in the direction perpendicular to the display surface of the display unit 42a also increases. Accordingly, in order to reduce the thickness of the shutter accessory 43, it is preferable to disperse and provide a plurality of shutter pieces. Conversely, if the number of sets of shutter piece sets is increased too much, the length of each shutter piece must be shortened due to the relationship with the accommodation space, and there is a possibility that the vicinity of the center portion of the display portion 42a cannot be shielded. . Accordingly, the appropriate number of shutter piece sets is naturally determined by the size of the display unit 42a and the shutter accessory 43 of the decorative symbol display device 42.

  (C) In the above embodiment, the shutter controller 43 is controlled by the sub-control device 262. However, the configuration is not limited to this, and the control may be performed by another control device such as the main control device 261. Good.

  (D) In the above-described embodiment, the first link mechanism including the first cam groove 781 and the first engagement shaft portion 760 is used as the link mechanism for interlocking the ring member 720 and the shutter piece set 715 (shutter pieces 731 to 734). The second link mechanism including the second cam groove 782 and the second engagement shaft portion 763 is illustrated, but the present invention is not limited to this, and any other configuration may be used as long as an interlocking relationship between them can be obtained. May be.

  For example, in the above-described embodiment, the first cam groove 781 and the second cam groove 782 which are cam portions are provided in the ring member 720, and the first engagement shaft portion 760 serving as an operated portion that receives an action from the cam portion. The second engagement shaft portion 763 is provided in the shutter piece set 715. Instead of this, for example, the cam portion may be provided in the casing 701 or the shutter piece set 715, and the ring member 720 may be provided with the operated portion.

  Further, the relationship between the cam portion and the actuated portion is not limited to the configuration including the cam groove and the protrusion portion loosely fitted thereto, and for example, a belt-like protrusion such as a rib is provided as the cam portion and engaged therewith. It is good also as a structure which provided the concave-shaped to-be-acted part.

  (E) In the above-described embodiment, the action section 781a of the first cam groove 781 and the non-interference section 782b of the second cam groove 782 have a shape formed by connecting a plurality of arcs having different curvatures. For example, the operation section 781a of the first cam groove 781 and the non-interference section 782b of the second cam groove 782 may be formed in a concentric arc shape. Moreover, not only a curve but a linear shape may be sufficient.

  (F) In the embodiment described above, the third shutter piece 733 and the second shutter piece 732 that move following the movement of the fourth shutter piece 734 are provided, but the member that moves following the movement may be omitted.

  (G) In addition to the decorative symbol display device 42 (liquid crystal display device) of the above embodiment, the display means shielded by the shutter accessory 43 is a CRT, dot matrix, LED, electroluminescence (EL), fluorescent display tube. A rotating drum or the like may be used.

  Further, instead of shielding the decorative symbol display device 42 as a display means for auxiliary effects as in the above embodiment, the identification information is variably displayed as in the special display device 39, and the identification information is specified in a specific manner. It is good also as a structure which shields the display means which displays definitely whether it is a big hit or not by carrying out stop display by.

  (H) You may implement as a different type of pachinko machine from the said embodiment. For example, the present invention may be implemented in a pachinko machine equipped with a variable winning device having a special winning area such as a V zone. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball can be implemented. Further, as a gaming machine other than a pachinko machine, it can of course be implemented as a slot machine as a swivel type gaming machine or a gaming machine in which a pachinko machine and a slot machine are integrated.

  (I) In the above-described embodiment, the second shutter piece 732 and the third shutter piece 733 do not receive power transmission directly from the ring member 720, but directly from the fourth shutter piece 734 by engagement with a rib or the like. By receiving an indirect action, the movement of the fourth shutter piece 734 is followed. Not limited to this, the second shutter piece 732 and the like may be configured to receive power transmission directly from the ring member 720 so as to be interlocked with the movement of the fourth shutter piece 734.

  Here, the shutter accessory 950 as an example of the embodiment will be described in detail with reference to FIGS.

  The shutter accessory 950 has a ring member 952 (see FIG. 56) as a power transmission member and 4 as a shielding member set with respect to the annular casing rear frame 951 (see FIG. 55) constituting the casing (base frame). After a set of shutter pieces 955 and the like are accommodated as shown in FIG. 57, they are integrated as one unit by assembling a casing front frame (not shown).

  57 to 60, in order to make the operation of the shutter piece set 955 easier to understand, illustrations other than main members such as the casing rear frame 951, the shutter piece set 955, and the ring member 952 are omitted, and the shutter piece set 955 is also shown. A dotted pattern is attached to the part.

  First, the shutter piece set 955 will be described in detail. The four shutter piece sets 955 are arranged at equal intervals along the circumferential direction of the casing rear frame 951.

  Each shutter piece set 955 is composed of three shutter pieces as shielding members. More specifically, as shown in FIG. 60 and the like, the first shutter piece 956 that is pivotally supported with respect to the casing front frame and the free end side of the first shutter piece 956 can be rotated (relatively). The second shutter piece 957 and the third shutter piece 958 are pivotally supported. In the present embodiment, the first shutter piece 956 corresponds to the first shielding member, the third shutter piece 958 corresponds to the second shielding member, and the second shutter piece 957 corresponds to the third shielding member.

  Each shutter piece set 955 is assembled so that the respective shutter pieces 956 to 958 are overlapped in the front-rear direction, and in the normal state of being accommodated in the casing, it is almost the same as the second and third shutter pieces 957 and 958. The whole is hidden behind the first shutter piece 956 (see FIG. 57).

  The first shutter piece 956 is formed with a rotating shaft portion 961 that is pivotally supported with respect to the casing front frame so as to protrude forward. Further, the first shutter piece 956 is formed with a first engagement portion 962 that is loosely fitted in a first cam groove 971 of a ring member 952 described later.

  A second engagement portion 967 is formed on the free end side of the second shutter piece 957 (the outer peripheral side at the time of relative rotational displacement). The second engaging portion 967 is loosely fitted in an auxiliary groove 951a provided in the casing rear frame 951.

  A third engagement portion 963 that is loosely fitted in a second cam groove 972 of a ring member 952 to be described later is formed on the free end side of the third shutter piece 958 (the outer peripheral side at the time of relative rotational displacement). In addition, an action portion 964 is provided in the vicinity of the third engagement portion 963. The action portion 964 is configured to be able to contact the second shutter piece 957 (second engagement portion 967), and acts on the second shutter piece 957 during a closing operation of the second shutter piece 957 described later. Is.

  Next, the ring member 952 for driving each shutter piece set 955 will be described in detail. The ring member 952 has a gear portion (not shown) formed on the back side thereof, and is driven by a motor unit (not shown) serving as a drive source. Then, each shutter piece set 955 is driven by a rotation operation along the circumferential direction of the casing rear frame 951.

  As shown in FIG. 56, four sets of first cam grooves 971 and second cam grooves 972 are provided on the surface portion of the ring member 952 corresponding to each shutter piece set 955.

  The first engagement portion 962 of the first shutter piece 956 is inserted into the first cam groove 971. The third engagement portion 963 of the third shutter piece 958 is inserted into the second cam groove 972.

  The first link mechanism configured by the first cam groove 971 and the first engaging portion 962 is for integrally rotating and displace the shutter piece set 955 (shutter pieces 956 to 958) around the rotating shaft portion 961. Mechanism. Therefore, in the present embodiment, the first cam groove 971 corresponds to the first cam portion, and the first engagement portion 962 corresponds to the first acted portion.

  On the other hand, the second link mechanism constituted by the second cam groove 972 and the third engaging portion 963 has the third shutter piece 958 to the first shutter piece 956 around the free end side of the first shutter piece 956. This is a mechanism for relative rotational displacement. Therefore, in the present embodiment, the second cam groove 972 corresponds to the second cam portion, and the third engagement portion 963 corresponds to the second operated portion.

  Similarly to the above embodiment, the first cam groove 971 includes an action section 971a that acts on the first engagement portion 962 when the shutter piece set 955 is integrally rotated and displaced, and the second shutter piece 957 and the third shutter. A non-interference section 971b that does not interfere with the first engagement portion 962 (the power of the ring member 952 is not transmitted) when the piece 958 is relatively rotationally displaced is provided.

  As for the second cam groove 972, as in the above embodiment, the action section 972a acting on the third engagement portion 963 and the shutter piece set 955 are integrally rotated when the third shutter piece 958 is relatively rotated and displaced. A non-interference section 972b that does not interfere with the third engagement portion 963 when the dynamic displacement occurs (the power of the ring member 952 is not transmitted).

  In addition, an action protrusion 973 that protrudes toward the inner periphery is formed on the inner periphery of the ring member 952. The action protrusion 973 is configured to be able to contact the second engagement portion 967 of the second shutter piece 957, and acts on the second shutter piece 957 when the second shutter piece 957 described later is opened. Is.

  Next, the operation of the shutter piece set 955 will be described in detail with reference to FIGS.

  Normally, the shutter piece set 955 is entirely accommodated in the casing in a state where the first to third shutter pieces 956 to 958 are superimposed (see FIG. 57). This state corresponds to the normal state of the shutter piece set 955, and the window portion 950a of the shutter accessory 950 is fully opened.

  From this state, when the ring member 952 is rotated counterclockwise by the motor unit, the first engaging portion 962 of the first shutter piece 956 becomes the curved wall portion of the action section 971a of the first cam groove 971. Is gradually moved toward the inner peripheral side of the ring member 952 while being pushed counterclockwise. Accordingly, the shutter piece set 955 (shutter pieces 956 to 958) is integrally rotated and displaced in the counterclockwise direction around the rotation shaft portion 961. Then, the shutter piece set 955 protrudes inside the window portion 950a of the shutter accessory 950. The counterclockwise direction corresponds to the first driving direction or the first direction in the present embodiment.

  At this time, the third engagement portion 963 of the third shutter piece 958 moves along the non-interference section 972b of the second cam groove 972 so as not to interfere with the rotation operation of the shutter piece set 955.

  As the ring member 952 further rotates, the tips of the four shutter piece sets 955 approach each other toward the central portion of the window portion 950a of the shutter accessory 950. When the ring member 952 is rotated by a predetermined amount, the tips of the four shutter piece sets 955 are brought into substantially contact with each other at the center portion of the window portion 950a of the shutter accessory 950 (see FIG. 58).

  In this state, the first engagement portion 962 of the first shutter piece 956 moves to the non-interference section 971b of the first cam groove 971, and the third engagement portion 963 of the third shutter piece 958 moves to the second cam. It moves to the action section 972a of the groove 972.

  From this point, when the ring member 952 continues to rotate in the counterclockwise direction, the third engagement portion 963 of the third shutter piece 958 is counterclockwise by the end wall portion of the action section 972a of the second cam groove 972. The free end side (the third engagement portion 963 side) of the third shutter piece 958 moves away from the first shutter piece 956. That is, an opening operation is performed in which the third shutter piece 958 rotates and displaces relative to the first shutter piece 956 around the free end side of the first shutter piece 956 as an axis.

  At this time, since the first engagement portion 962 of the first shutter piece 956 is in the non-interference section 971b of the first cam groove 971, the driving force of the ring member 952 is the first shutter piece 956 (first engagement portion 962). Not communicated to. Accordingly, the third shutter pieces 958 are opened from the first shutter pieces 956 while the first shutter pieces 956 are held substantially in contact with each other at the center of the window 950a.

  Further, when the ring member 952 continues to rotate in the counterclockwise direction, the third shutter piece 958 continues to open, and the action protrusion 973 of the ring member 952 moves to the second engagement portion of the second shutter piece 957. 967 is caught. The second engagement portion 967 is pushed counterclockwise by the action projection portion 973, so that the free end side (second engagement portion 967 side) of the second shutter piece 957 is the back side of the first shutter piece 956. It is pushed out further (see FIG. 59). Thereafter, the second shutter piece 957 performs an opening operation in conjunction with the movement of the third shutter piece 958, similarly to the third shutter piece 958.

  Then, when the ring member 952 rotates by a predetermined amount, the third shutter piece 958 of the predetermined shutter piece set 955 is in a state of being substantially in contact with the first shutter piece 956 of another adjacent shutter piece set 955 (FIG. 60). In this state, the window portion 950a of the shutter accessory 950 is fully closed by the four shutter piece sets 955. At this time, the second engagement portion 967 of the second shutter piece 957 is sandwiched between the action projection portion 973 of the ring member 952 and the end portion of the auxiliary groove 951a of the casing rear frame 951, whereby the second shutter portion 957 is sandwiched. The piece 957 is held in an undisplaceable state.

  On the other hand, when the four sets of shutter pieces 955 return to the original state, the procedure reverse to the above procedure is followed. That is, when the ring member 952 is rotated in the clockwise direction by the motor unit, the third engagement portion 963 of the third shutter piece 958 is rotated counterclockwise in the action section 972a of the second cam groove 972. The third shutter piece 958 is pushed in the clockwise direction by the curved wall portion on the direction side, and the third shutter piece 958 starts the relative rotational displacement in the clockwise direction around the free end side of the first shutter piece 956, that is, the closing operation. To do. The clockwise direction corresponds to the second driving direction or the second direction in the present embodiment.

  When the ring member 952 continues to rotate in the clockwise direction, the third shutter piece 958 continues to close toward the first shutter piece 956, and the third shutter piece 958 enters so as to be hidden behind the second shutter piece 957. .

  Then, the action portion 964 of the third engagement portion 963 is caught near the root portion of the second engagement portion 967 of the second shutter piece 957. Then, when the second engaging portion 967 is pushed clockwise by the action portion 964, the second shutter piece 957 is interlocked with the movement of the third shutter piece 958 in the same manner as the third shutter piece 958. The closing operation will be started.

  Further, when the ring member 952 continues to rotate in the clockwise direction, the third shutter piece 958 and the second shutter piece 957 enter so as to be hidden behind the first shutter piece 956.

  During the closing operation of the third shutter piece 958 and the second shutter piece 957 as described above, the driving force of the ring member 952 is the first shutter piece 956 ( The first engagement portion 962) is not transmitted. Accordingly, the third shutter piece 958 and the second shutter piece 957 are gathered to the first shutter piece 956 while the first shutter pieces 956 are held in a state of being substantially in contact with each other at the central portion of the window portion 950a. Go.

  When the ring member 952 continues to rotate in the clockwise direction, the first engagement portion 962 of the first shutter piece 956 moves to the action section 971a of the first cam groove 971 and the third engagement of the third shutter piece 958. The joining portion 963 moves to the non-interference section 972b of the second cam groove 972. Then, the first engagement portion 962 of the first shutter piece 956 is gradually pushed clockwise by the counterclockwise curved wall portion of the action section 971a of the first cam groove 971, and gradually the ring member. It moves to the outer peripheral side of 952. Accordingly, the shutter piece set 955 (respective shutter pieces 956 to 958) is integrally rotated and displaced in the clockwise direction around the rotation shaft portion 961. At this time, the third engagement portion 963 of the third shutter piece 958 moves along the non-interference section 972b of the second cam groove 972 so as not to interfere with the rotation operation of the shutter piece set 955.

  In this way, when the shutter piece set 955 is immersed in the casing and the shutter piece set 955 returns to the normal state, the window 950a of the shutter accessory 950 is fully opened.

  (J) In the above embodiment, the angle α of the tip of each first shutter piece 731 viewed from the front of the shutter accessory 43 is 90 °, and each first shutter piece of the four shutter piece sets 715 is set. When the tip of 731 is in a substantially abutting state at the center of the window 43a of the shutter accessory 43, the vicinity of the center of the window 43a is shielded with almost no gap. Of course, the configuration is not limited to this, and the front ends of the first shutter pieces 731 of the four shutter piece sets 715 may be in contact with each other without any gap.

  Further, from the viewpoint of shielding the vicinity of the central portion of the window 43a with almost no gap, when the number of the shutter piece sets 715 is different from that of the above embodiment, the angle α of the tip of each first shutter piece 731 is set to the set. It is preferable to set the angle according to the number. For example, when three sets of shutter pieces 715 are provided, it is preferable that the angle α of the tip of each first shutter piece 731 is 120 ° (360 ° / 3). That is, when there are n sets of shutter piece sets 715 (n is a natural number of 2 or more), it is preferable that the angle α of the tip of each first shutter piece 731 is 360 ° / n.

  (K) In the above embodiment, when the first shutter piece 731 performs the rotational displacement operation, the second to fourth shutter pieces 732 to 734 do not perform the relative displacement operation, and the second to fourth shutter pieces 732 When ˜734 performs the relative displacement operation, the first shutter piece 731 is configured not to perform the rotational displacement operation. Not limited to this, a time when the first shutter piece 731 and the fourth shutter piece 734 and the like operate simultaneously may be provided. For example, the first shutter piece 731 may be displaced together with the relative displacement operation of the fourth shutter piece 734 and the like. However, in this case, the rotation shaft portion 745 that is pivotally supported by the casing 701 needs to be assembled to the casing 701 so as to be displaceable. Conversely, the fourth shutter piece 734 or the like may start a relative displacement operation while the first shutter piece 731 is rotationally displaced. Further, after the relative displacement operation of the fourth shutter piece 734 or the like is started, the rotational displacement of the shutter piece set 715 (first shutter piece 731) may be started.

  (L) In the above embodiment, the four shutter piece sets 715 are configured to perform the same operation. However, the present invention is not limited to this, and the operation of the integral rotation displacement operation and the relative displacement operation of each shutter piece set 715 is not limited thereto. It is good also as a structure from which an aspect differs. Such a configuration can be realized by changing the configuration of each link mechanism corresponding to each shutter piece set 715, in particular, the shape of the first cam groove 781 and the second cam groove 782.

  (M) The shape of the first cam groove 781 and the second cam groove 782 is not limited to the above embodiment. For example, it is good also as a structure provided with the other action area different from the action area 781a in the middle of the non-interference area 781b of the 1st cam groove 781, or a clockwise direction side edge part. With such a configuration, a further multi-stage operation mode can be realized.

  (N) In the above embodiment, as an example of the shielding device, the shutter accessory 43 that shields the display unit 42a of the decorative symbol display device 42 is illustrated, but the present invention is not limited to this, and other objects are shielded. It may be.
