  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail with reference to the drawings. FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view showing a state in which a front frame set 14 is opened with respect to an outer frame 11 and an inner frame 12 described later. In the present embodiment, the inner frame 12 corresponds to the gaming machine main body, and the front frame set 14 corresponds to the front door.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is supported on one side of the outer frame 11 so as to be openable and closable. ing. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, the structure can be easily reused as compared with the conventional structure in which the plates are assembled using nails and rivets. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm).

  The inner frame 12 and the front frame set 14 are made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By using a synthetic resin for molding both, it is possible to cope with a more complicated shape as compared with the case of using a metal material, and it is also possible to suppress an increase in production cost. Advantages of using ABS include a low production cost, strong viscosity, and high impact resistance compared to resin materials such as polycarbonate. In addition, for example, when a coating process such as plating is performed on a design surface such as the front side of the front frame set 14, the process is relatively easy to perform, and there is an advantage that a product with higher appearance quality can be manufactured.

  The opening / closing axis of the inner frame 12 is set so as to extend vertically on the left side (opposite to the place where the handle 18 described later) is installed as viewed from the front of the pachinko machine 10, and the inner frame 12 is centered on the opening / closing axis. Can be opened forward. The outer frame 11 may be made of a light metal such as resin or aluminum.

  A lower tray unit 13 is attached to the inner frame 12 at the lowermost portion, and a front frame set 14 is attached to correspond to a range excluding the lower tray unit 13. The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. The front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 is located on the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened. FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 3, the structure in the game area on the game board 30 is shown as blank for convenience). Note that a rib R1 projects from the front side of the inner frame 12 at a periphery thereof (a portion corresponding to the front frame set 14). When the front frame set 14 is closed, the front frame set 14 is fitted into the rib R1. With this configuration, it becomes difficult to allow a wire or the like to enter from the gap between the front frame set 14 and the inner frame 12 and plays a role in preventing fraud.

  The lower tray unit 13 is provided with a lower tray 15 as a ball receiving tray at a substantially central portion, so that game balls discharged from the outlet 16 can be stored in the lower tray 15. Most of the lower dish unit 13 is molded of ABS resin like the inner frame 12, but the surface layer forming the lower dish 15 and the front panel 23 at the back of the lower dish are particularly flame retardant. Molded with ABS resin. For this reason, this part is difficult to burn. Reference numeral 24 denotes a sound output port from the speaker, and reference numeral 25 denotes a ball release lever for discharging the game ball from the lower plate 15 downward.

  A game ball launching handle (hereinafter simply referred to as “handle”) 18 is disposed on the right side of the lower plate 15 so as to protrude to the front side. That is, the handle 18 is positioned on the right side when viewed from the front of the pachinko machine 10 on the side opposite to the opening / closing axis of the inner frame 12, and a predetermined opening amount when the inner frame 12 is opened regardless of the protrusion of the handle 18. It can be secured. An ashtray 26 is provided on the left side of the lower plate 15. The ashtray 26 has a so-called cantilever structure that is rotatably supported by a shaft rod (not shown) protruding leftward from the left side of the lower tray 15.

  On the other hand, an upper plate 19 serving as a ball receiving plate is provided above the lower plate 15. Here, the upper tray 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device while aligning them in a line. In addition, the upper plate 19 is integrally formed with a glass frame portion that supports glass to be described later in the front frame set 14. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame below the glass frame is provided, and an upper plate is provided on the front decorative frame. On the other hand, since the upper plate 19 is provided directly and integrally, even if the width of the frame portion of the front frame set 14 is relatively narrow as compared with the prior art, as will be described later, the front frame set 14 (glass frame Part) can be secured. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  In FIG. 3, the inner frame 12 is mainly composed of a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20. A game board 30 is detachably mounted on the rear side of the resin base 20. The game board 30 is made of a rectangular plywood, and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The vertical length of the game board 30 is 476 mm, and the horizontal length is 452 mm (same size as before). The resin base 20 is provided with an opening detection sensor 22 that detects opening of the front frame set 14. Although not shown, an open detection switch for detecting the opening of the inner frame 12 is also provided.

  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 is formed with a general winning port 31, a variable winning device 32, a large port (starting port) 33, a small port (through gate) 34, a variable display unit 35, and the like as specific pitching means by router processing. The game board 30 is attached from the front side with a wood screw or the like. As is well known, a game ball enters the general winning port 31, the variable winning device 32, and the big port 33, and a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15) by the output of a detection switch described later. It is. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (acts) such as a windmill.

  The variable display unit 35 includes a small symbol display device 41 that displays a small symbol in a variable manner with the passage of the small accessory 34 as a trigger, and a variable display that displays a large symbol as identification information in a variable manner with a winning at the big mouth 33 as a trigger. A large symbol display device 42 as a device is provided. The accessory symbol display device 41 includes an accessory symbol display unit 43 and a holding lamp 44. Each time a game ball passes through the accessory port 34, for example, the display symbol (the accessory symbol) by the display unit 43 changes. When the variable display stops at a predetermined symbol, the big mouth 33 is configured to be activated (opened) for a predetermined time. When a game ball newly passes through the accessory mouth 34 during the accessory symbol variation display on the display unit 43 of the accessory symbol display device 41, the corresponding accessory symbol variation display is performed at that time. The configuration is performed after the end of the variable display. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. ing. However, the maximum number of holding times is not limited to this. For example, the maximum number of times of holding may be set to 8 in order to wait for the display of variation of the accessory symbol for 8 times. The display unit 43 may have a configuration in which the display is variably displayed on a part of the large symbol display device 42 (liquid crystal display device) in addition to a configuration in which the display is variably displayed by switching lighting of a plurality of lamps. Similarly, the hold lamp 44 may be configured to be variably displayed on a part of the large symbol display device 42.

The large symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device 45 described later. The large symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are variably displayed on the large symbol display device 42 so as to be scrolled for each symbol row. In the present embodiment, the large symbol display device 42 (liquid crystal display device) includes a large liquid crystal display of 8 inches. The variable display device unit 35 is provided with a center frame 47 so as to surround the large symbol display device 42.
The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated between an open state in which a game ball is easy to win and a normal closed state in the event of a big win. ing. More specifically, when a game ball wins the big game mouth 33, the big game symbol display device 42 displays the symbols in a variable manner, and the final symbol is a combination of specific symbols set in advance. A gaming state occurs. The large 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 game (a big hit state as a special game state). Specifically, the passage of a predetermined time or a predetermined number of winnings is taken as one round, and the large opening of the variable winning device 32 is repeatedly opened a predetermined number of times.

  When a game ball newly wins the big game mouth 33 during the symbol variation display of the large symbol display device 42, the corresponding symbol variation display is performed after the end of the symbol variation display being performed at that time. It has a configuration. That is, the symbol variation display is waited (held, stored) (storage means). Although the maximum number of symbol variation displays to be held is determined for each pachinko machine model, in this embodiment, up to 4 times are held, and the number of times the hold is held is displayed by the hold lamp 46. It has become. However, the maximum number of holding times is not limited to this. For example, the maximum number of holdings may be set to 8 in order to wait for 8 symbol fluctuation displays. Note that the hold lamp 46 may be configured so as to be variably displayed on a part of the large symbol display device 42.

  Further, the game board 30 is provided with a rail unit 50 for guiding the game balls launched from the game ball launching device to the upper part of the game board 30, and the game balls launched by the turning operation of the handle 18. Are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product, and includes an inner rail constituent part (inner rail part) 51 and an outer rail constituent part (outer rail mounting part) 52 that are integrally formed in an inner and outer double. Have. The inner rail constituting portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion. Further, the outer rail constituting portion 52 is formed so that a part (mainly the left side portion) faces the inner rail constituting portion 51. In such a case, the inner rail constituting portion 51 and the outer rail constituting portion 52 mainly constitute a guide rail, and each of the rail constituting portions 51 and 52 is guided by a ball by a portion (left portion toward the left) that is parallel with a predetermined interval. A passage is formed. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail constituting portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide passage between the inner rail constituting portion 51 and the outer rail constituting portion 52 to the upper portion of the game board 30 returns to the ball guide passage again. It is like that. Further, a return rubber 54 is attached to the outer rail constituting portion 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail constituting portion 52). . Therefore, the game ball launched at a predetermined momentum or more hits the return rubber 54 and is returned to, for example, the substantially central portion side of the game board 30. On the inner side surface of the outer rail constituting portion 52, a sliding plate 55 is attached as a long metal strip made of stainless steel so that the flight of the game ball is smoother. In the present embodiment, the outer rail constituting portion 52 and the sliding plate 55 constitute a so-called conventional outer rail. Then, by making the inner and outer rail components 51 and 52 and the sliding plate 55 into a unit as the rail unit 50, the mounting operation becomes easier and the workability is improved as compared with the conventional configuration in which the inner and outer rails are separately provided.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, fixing means such as screws are inserted into the plurality of through holes formed in the flange 56. Thus, the rail unit 50 can be fastened to the game board 30. Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially straight line (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50, and the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing. The lower left flange 56 uses more fixing means than the other parts (upper left, upper right and lower right flanges 56). This is for fixing the positions of the guide rail and the ball guide passage to more appropriate positions, whereby the game ball launched from the game ball launching device is more stably guided to the upper part of the game board 30. In addition, the rail unit 50 can be more firmly fixed by increasing the number of fixing means, and even if distortion occurs when the rail unit 50 is molded, there is an effect of absorbing the distortion.

  A convex portion 57 is formed at the entrance of the spherical guide passage between the inner rail constituting portion 51 and the outer rail constituting portion 52 so as to close a part of the spherical guide passage. This convex portion 57 is provided in a substantially vertical direction from the inner rail constituting portion 51 to the lower end portion of the rail unit 50, and a foul ball that does not reach the game area and flows backward in the ball guide passage is used as a foul ball passage 63 (see FIG. 3). ). Note that the lower right corner and the lower left corner of the game board 30 are spaces for attaching seals and plates (S1, S2 in FIG. 4) such as certificate stamps, etc., in order to secure this attachment space. The notches 58 and 59 are formed in the flange 56.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner peripheral part (inner and outer rail constituent parts 51 and 52) of the rail unit 50. In particular, in this embodiment, the game area is partitioned on the board surface of the game board 30. Is much larger than before. In the present embodiment, the distance from the uppermost point of the outer rail component 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the inner rail component 51 from the extreme left position of the outer rail component 52. The distance to the extreme right position is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail component 51 to the extreme right position of the inner rail component 51 is 418 mm.

  In the present embodiment, when the game area is viewed from the front of the pachinko machine 10, guidance that is a parallel part of the inner and outer rail constituting parts 51 and 52 among the area surrounded by the inner rail constituting part 51 and the outer rail constituting part 52. The area excluding the rail area. Therefore, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail component 52 but by the inner rail component 51. Similarly, the right limit position toward the game area is specified by the inner rail constituting unit 51. The lower limit position of the game area is specified by the lower end position of the game board 30. Further, the upper limit position of the game area is specified by the outer rail component 52.

  Therefore, in the present embodiment, the width of the game area (maximum width in the left-right direction) is 418 mm, and the height of the game area (maximum width in the vertical direction) is 445 mm.

  Here, the width of the gaming area is preferably at least 380 mm. More preferably, it is 390 mm or more, 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. Of course, it may be 470 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more, 480 mm or more, and 490 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. In addition, about the combination of the said width | variety and height, it is good also as what combined the said numerical value arbitrarily.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is much larger than the conventional area ratio. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the past, so it can be said that the game area is considerably expanded on the premise that the game board 30 is shared. It should be noted that the external shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 must be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more.

  Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 10 is about 40%, which is a much larger area ratio than before. The area ratio of the game area to the area of the front side of the entire pachinko machine 10 is desirably 35% or more. Of course, it may be 40% or more, 45% or more, or 50% or more.

  The accessory openings 34 located on both sides of the variable display device unit 35 have a guide mechanism that allows the game balls that have passed through the accessory opening 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central big mouth 33 or the variable winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Furthermore, by extending the game area in the left-right direction, various accessories 34, a windmill, a plurality of nails (guide nails for guiding a game ball to the center), and other accessories can be arranged. Thus, the behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. In addition, since the game area is also expanded in the vertical direction, it is possible to further arrange various accessory ports 34, windmills, a plurality of nails, and other accessories, and the game balls in the vertical direction in the game area can be arranged. The behavior can be made even more interesting.

  Returning to the description of FIG. 3, in the resin base 20, below the window hole 21 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher is attached. Yes. The firing rail 61 is fixedly attached to the resin base 20 integrally with the metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the handle 18 is first launched obliquely upward along the launch rail 61 and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It is like that.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded compared to the conventional case, but under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than that of the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launching device can be guided to the guide rail in a more stable state. Particularly in this case, the launch rail 61 is formed so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area. In addition, since the launch rail 61 has the above-described configuration, in the present embodiment, the metal plate 62 is also relatively larger than the conventional one, and the number of fixing means for fixing the metal plate 62 is larger than the conventional one.

  Further, there is a gap of a predetermined interval between the firing rail 61 and the rail unit 50 (guidance rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball fired from the game ball launching device does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate 15. To be discharged. Incidentally, in the case of the present embodiment, the length of the firing rail 61 is about 240 mm, and the length of the gap at the tip of the firing rail (the length on the extension line of the firing rail 61) is about 40 mm.

  When the foul sphere flows backward in the guide rail, most of the foul sphere flows along the outer rail constituting portion 52 and drops downward when reaching the lower end portion of the outer rail constituting portion 52. May be ramped in the guide rail and jump to the inner rail component 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. This suppresses interference between the foul ball and the next game ball to be launched.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front frame set 14 side (ball outlet leading from the most downstream portion of the upper plate 19). At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large, but in the vicinity of the base end portion of the launch rail 61, its right side and Guide members 65 and 66 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launcher is provided with a hitting ball basket, and the game ball is shot with the rotation of the hit ball bowl around the shaft portion. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to light metal such as aluminum and reducing the size of the shaft, the head portion of the hitting ball (on the side opposite to the shaft) is secured to ensure sufficient firing force. A weight is provided at the end. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, it is possible to easily pick or hit the hitting ball, and it is easy to adjust the hitting strength of the hitting tip.

  In addition, the code | symbol 67 in FIG. 3 is the discharge port connected to the upper plate 19, and a game ball is discharged to the upper plate 19 through this discharge port 67. FIG. An open / close shutter 68 is attached to the discharge port 67. Although detailed disclosure of the drawings is omitted, the shutter 68 is rotatable about the shaft portion provided along the lower side portion thereof, and is in a state where the front frame set 14 is opened (state of FIG. 3). The shutter 68 substantially closes the discharge port 67 by a biasing force such as a spring. When the front frame set 14 is closed, the shutter 68 is pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14. Note that the game ball is discharged to the lower plate 15 in the opened state of the front frame set 14. Therefore, as described above, in the pachinko machine 10 configured such that the upper plate 19 is directly provided with respect to the front frame set 14, the game balls in the payout passage and the like are spilled off when the front frame set 14 is opened. Can be prevented.

  The resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Accordingly, a seal or the like (S1 in FIG. 4) stretched at the lower right corner of the game board 30 can be viewed through the small window 71. It is also possible to affix the above-mentioned sticker or the like from this small window 71.

  Further, the resin base 20 is provided with a substantially rectangular small window 72 at the upper left of the window hole 21, and a substantially rectangular hole 73 (see FIG. 4) corresponding to the small window 72 is also formed in the upper left part of the game board 30. Reference) is provided. Various electrical wirings (not shown) connected to the electric decorations 102 and 103 of the front frame set 14 to be described later are led from the back side of the pachinko machine 10 through the small window 72 and the hole 73.

  Further, support metal fittings 81 and 82 are attached to the left end portion of the inner frame 12 in FIG. 3 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction.

  The inner frame 12 is provided with grounding metal fittings E1 and E2 (see FIG. 3). The grounding metal fittings E1 and E2 are connected to predetermined metal parts on the back side of the inner frame 12. Then, in a state where the front frame set 14 is closed, the grounding metal fittings E1 and E2 are short-circuited by coming into contact with reinforcing plates 131 and 132 described later.

  Next, the front frame set 14 will be described with reference to FIGS. FIG. 5 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear. In the present embodiment, the distance between the upper end of the window portion 101 (the uppermost portion of the outer rail constituting portion 52 and the upper end of the game area) and the upper end of the front frame set 14 (the so-called upper and lower width of the upper frame portion) is 61 mm. It is significantly shorter than the prior art with an upper frame width of about 85 mm to 95 mm. As a result, the upper area of the game area can be easily secured, and the large variable display device unit 35 can also be arranged relatively upward. The distance between the upper end of the front frame set 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

  Further, the shortest distance between the left end of the window portion 101 and the left end of the front frame set 14 when viewed from the front of the pachinko machine 10 (the left-right width of the so-called left side frame portion: shown on the right side in FIG. 5), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as apparent from comparison between FIGS. 1 and 3, in the state where the front frame set 14 is closed, not only the left end portion of the outer rail constituting portion 52 but also the left end portion of the inner rail constituting portion 51 is Covered by the left frame. That is, at least a part of the guide rail overlaps and is covered with the left frame portion of the front frame set 14 when viewed from the front of the pachinko machine 10. Even if it becomes difficult to visually recognize the game ball in this way, it is only a passing point where the game ball is guided to the game area, and it is difficult to see the game ball in the game area where the player mainly enjoys the game. It doesn't mean. Therefore, there is no trouble in actual game. Moreover, while such a trouble does not arise, sufficient intensity | strength and support strength of the front frame set 14 are securable. Incidentally, the distance in the left-right direction between the left end position of the outer rail component 52 and the left end position of the outer frame 11 when viewed from the front of the pachinko machine 10 is 21 mm, and the right end position of the game area (the right end position of the inner rail component 51). The distance in the left-right direction from the right end position of the outer frame 11 is 44 mm.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light-emitting means play a role of enhancing the effect of the game by controlling the light-emission mode such as lighting and flashing according to the change of the game state at the time of big hit or the reach as a state just before a special game It is. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks when the jackpot is informed that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. Further, a small window 107 to which a transparent resin is attached is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102. In the present embodiment, the reach state includes a state in which the symbol variation of the right symbol sequence stops at the same type of symbols as the stop symbol of the left symbol sequence.

  In the reach state, various reach state patterns (reach patterns) are set in addition to “normal reach” in which the symbols in the middle symbol row are simply scrolled as in the case of normal fluctuation. Among these reach patterns, reach patterns other than “normal reach” are so-called “super reach”. When the operation of “super reach” is started, the expected value (expected value for jackpot) at which a big hit state occurs is higher than in the case of “normal reach”. Also, in “super reach”, the jackpot expectation value may differ depending on each reach pattern. In addition, it is possible to prepare a reach pattern called “special reach” having a higher expected value than “super reach” or “premium reach” in which the occurrence of a big hit state is confirmed and displayed.

  Further, each reach pattern is weighted, and the probability that each reach pattern is selected is individually different. Specifically, the probability of selecting “super reach” is set lower than the probability of selecting “normal reach”. In addition, the probability of selecting “special reach” is set lower than “super reach”. In addition, “Premium Reach” is set so that it is hardly selected. In the present embodiment, the probability that each reach pattern is selected differs depending on whether it is a big hit or not.

  In addition, in the effect display mode of the big game symbol display device 42 that is changed in symbol, an effect other than the reach effect may be performed from the start of change of all symbol sequences to the final stop display. Productions other than the reach production include production such as slip fluctuation, re-variation, reach suggestion, super reach suggestion, and jackpot suggestion. Here, “suggestion” only needs to be able to suggest that a predetermined gaming state is likely to occur (a predetermined display mode on the large symbol display device 42 is easily displayed) depending on the performance. Alternatively, there is no problem even if there is a case where the predetermined gaming state does not occur because the effect has an influence on the occurrence of the predetermined gaming state.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. If the ball lending operation unit 120 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. . The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 19 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine is achieved.

  Various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcing plates 131, 132, 133, and 134 are respectively attached to the back side of the front frame set 14 and on the top, bottom, left, and right sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. That is, in the reinforcing plates 131 to 134, electricity is prevented from passing in an annular shape due to the insulating effect of the resin part 135. Thereby, generation | occurrence | production of the magnetic field by the loop of a noise in the reinforcement boards 131-134 and cyclic | annular electricity supply can be suppressed.

  The right reinforcing plate 131 in FIG. 5 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is a hole portion of the inner frame 12 with the front frame set 14 closed. It is comprised so that it may be engaged with 12a (refer FIG. 3). With this configuration, the front frame set 14 is configured to include the upper plate 19, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

  The lower reinforcing plate 134 is provided with a resin rail side wall member 136 at a position facing the firing rail 61 (see FIG. 3). The rail side wall member 136 becomes the side wall of the firing rail 61 when the front frame set 14 is closed. Therefore, the game ball is prevented from spilling from the launch rail 61.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and a part of the reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows on the front and rear sides, and glass 137 as a pair of front and rear transparent members having a rectangular shape is held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

  As described above, in the pachinko machine 10 of the present embodiment, the game area is expanded. Therefore, when the front frame set 14 is closed, the guide rail configured by the inner and outer rail components 51 and 52 is used. Is partially covered by the front frame set 14. Therefore, in the guide rail, a portion where the front open portion cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 53, the game ball spills out (jumps out) from the guide rail, and the outer rail component 52 There is a risk of being caught between the glass 137 and the like. Therefore, in the present embodiment, a rail cover 140 for covering the front side open portion of the guide rail is attached to the front frame set 14.

  The rail cover 140 is a substantially flat plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the guide rail, and covers the section from the base end portion of the guide rail to the vicinity of the tip end portion along the peripheral edge of the window portion 101. It is attached to the back side of the set 14. In particular, the dimensions and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail constituting portion 51. When the rail cover 140 is attached, the surface side of the rail cover 140 is in contact with the glass 137. When the front frame set 14 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide rail. Thereby, the collision of the game ball with the glass 137 can be prevented in most sections of the guide rail. Therefore, adverse effects such as breakage due to contact with the glass 137 can be suppressed.

  Further, a portion where the guide rail protrudes from the side edge portion of the glass 137 is provided at the right end portion of the rail cover 140 (that is, the portion which becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front frame set 14). A covering portion 141 for covering is provided. Thereby, it is possible to prevent the occurrence of problems such that the game ball spills out of the guide rail (jumps out) or gets caught between the outer rail component 52 and the glass 137.

  Further, on the back side of the rail cover 140, a ridge 142 is formed that extends in an arc along the inner edge of the rail cover 140 and protrudes toward the front side of FIG. The ridge 142 is configured to substantially overlap the inner rail constituting portion 51 in a state of entering the guide rail in a state where the front frame set 14 is closed. Therefore, for example, even if a wire or the like is intruded through a gap between the front frame set 14 and the inner frame 12 to perform an illegal act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. In addition, it is good also as a structure which forms the protrusion 142 in a wider range, for example along the whole region of the inner edge of the rail cover 140. According to this structure, it becomes difficult to infiltrate a wire etc. in a wider range, a wire etc. It is possible to more reliably prevent fraud performed using

  Further, support metal fittings 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Therefore, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side. It comes to be installed. Here, the support mechanism will be described in more detail based on the relationship between the support fittings 81 and 82 and the support fittings 151 and 152. The support fitting 151 has a substantially rod shape, and the upper diameter is larger than the lower diameter. The width of the cutout of the support hole 83 is narrower than the thickness of the upper portion of the support fitting 151 and wider than the thickness of the lower portion. As a mounting procedure for the front frame set 14, first, the lower portion of the support fitting 151 is inserted into the support hole 83 through the notch, and then the support fitting 152 is inserted into the protruding shaft 84 of the support fitting 82. Then, by positioning the upper portion of the support fitting 151 corresponding to the notch position, the support fitting 151 is not detached from the support hole 83, and the mounting of the front frame set 14 is completed.

  The locking mechanism of the front frame set 14 is integrated with the locking mechanism of the inner frame 12, and the main body of the integrated locking mechanism G1 (see FIG. 6) is provided on the back side of the inner frame 12. It has been. Therefore, in FIG. 3, only the locking claws T1 and T2 protruding from the locking mechanism G1 to the front side of the inner frame 12 are shown. Then, the locking claws T1 and T2 are locked to the back side of the front frame set 14, whereby the front frame set 14 is locked. The locking mechanism G1 constitutes the locking device in the present embodiment.

  Here, the configuration of the locking mechanism G1 will be described with reference to FIG. The locking mechanism G1 is provided so as to extend in the vertical direction and to be movable in the vertical direction on one side of the inner frame 12 constituting the main body of the gaming machine (right side, left side in FIGS. 6 and 8). The long interlocking member G2 and the one side part of the inner frame 12 are provided at a position different from the position that is the maximum width in the left-right direction of the game area, and the interlocking member G2 is selectively moved upward or downward. A key member G3 (see FIGS. 6, 9 and the like) to be moved, and the locking of the inner frame 12 is released by the movement of the interlocking member G2 up and down by the operation of the key member G3, and the upper and lower other of the interlocking member G2 The front frame set 14 is unlocked by the movement to.

  Next, the configuration of the back surface of the pachinko machine 10 will be described in detail. FIG. 6 is a rear view of the pachinko machine 10.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. In the pachinko machine 10, various control boards are arranged on the back side (actually the back side of the inner frame 12 and the game board 30) so as to be arranged vertically or horizontally, or to be stacked in front and back, A game ball supply device (payout mechanism) for supplying game balls, a protective cover made of resin, and the like are attached. In this embodiment, various control boards are divided into two mounting bases to form two control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. ing. In this case, the main board and the sound lamp control board are mounted on one mounting base to form a unit, and the dispensing control board, launch control board, and power supply board are mounted on the other mounting base to form a unit. Here, for convenience, the former unit is referred to as “first control board unit 201”, and the latter unit is referred to as “second control board unit 202”.

  In addition, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203”. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured so that they can be attached and detached without using any tools or the like in units of units. It is provided and can be opened and closed with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  Actually, the units 201 to 203 are arranged and attached as shown in the schematic diagram of FIG. In FIG. 7, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Further, the back pack unit 203 is arranged in a region partially overlapping the first control board unit 201.

  Specifically, the first control board unit 201 is provided with a support shaft part M1 at the left end portion when viewed from the back of the pachinko machine 10, and the first control board unit 201 is centered on the axis A by the support shaft part M1. It can be opened and closed.

Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like on the left end portion thereof (that is, on the side opposite to the support shaft portion, more specifically, on the open end side), and at the upper end portion and lower end portion, respectively The backpack unit 203 is fixedly held to the main body of the pachinko machine by the fastening part M7 and the locking parts M8, M9.

  In this case, the development directions of the units 201 to 203 are not the same, and the first control board unit 201 opens to the left when viewed from the back of the pachinko machine 10, whereas the second control board unit 202 and the back pack unit. 203 is configured to open to the right.

  On the other hand, FIG. 8 is a rear view showing the configuration of the game board 30 assembled to the inner frame 12. FIG. 9 is a perspective view of the inner frame 12 as viewed from the rear. Here, the back side structure of the inner frame 12 and the game board 30 will be described with reference to FIGS. 8 and 9.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 20 and does not fall off by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated to switch between a fixed position (lock position) and a fixed release position (unlock position). FIG. 8 shows a locked state. The locking fixtures 211 at the three left and right sides of the game board 30 are L-shaped metal fittings formed by bending metal pieces, and are configured not to protrude outwardly from the inner frame 12 when the game board 30 is fixed. Note that the locking fixture 212 at one lower portion of the game board 30 is an I-shaped fastener made of resin.

  A variable display device unit 35 is disposed in the center of the game board 30. In the variable display device unit 35, a frame cover 213 made of resin (for example, made of ABS) that covers the center frame 47 (see FIG. 3) from behind is provided to protrude rearward, and at the rear end of the frame cover 213, A large-sized symbol display device 42 as a liquid crystal display device and a display control device 45 are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 are disposed.

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, it corresponds to the game board opening of the general prize opening 31, the variable prize winning device 32, and the big prize opening 33 (see FIG. 3 respectively) described above, and gathers in one place on the downstream side. A recovery passageway 216 is formed. In addition, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is also attached to the inner frame 12 below the game board 30, and discharge balls are sent to the outside of the pachinko machine 10 in the discharge passage board 217. A discharge passage 218 for guiding is formed. Therefore, as illustrated in phantom lines in FIG. 8, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further the discharge passage 218 of the discharge passage board 217. Through the pachinko machine 10. In addition, the out port 36 (see FIG. 3) similarly communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

  In the above configuration, with the lower end surface of the game board 30 as a boundary, a back frame set 215 (collection passage 216) is provided on the upper side, and a discharge passage board 217 (discharge passage 218) is provided on the lower side. The game board 30 is provided without overlapping (overlapping) in the front-rear direction. Therefore, when removing the game board 30 from the inner frame 12, there is no inconvenience that the discharge passage board 17 prevents the game board from being removed.

  The discharge passage board 217 is provided just behind the upper plate 19 on the front surface of the pachinko machine. A wire or the like is inserted from a ball discharge port (ball passage rod 69 in FIG. 2) leading to the upper plate 19, An illegal act of causing a wire or the like to enter the game area side through a gap between the inner frame 12 and the discharge passage board 217 can be considered. Accordingly, in the pachinko machine 10, a plate 219 extending in front of the pachinko machine so as to overlap the inner frame 12 almost integrally is provided just behind the upper plate 19 of the discharge passage board 217. Therefore, even if a wire or the like tries to enter from the gap between the inner frame 12 and the discharge passage board 217, it is obstructed by the plate 219, and it becomes very difficult to make the wire or the like enter the game area. As a result, an illegal act such as forcibly opening the variable winning device 32 (large opening) using a wire or the like can be prevented.

  In addition, on the back surface of the game board 30, a winning detection mechanism for detecting the passage of game balls such as various winning holes is provided. Specifically, a prize opening switch 221 is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and a specific area switch 222 and a count switch 223 are provided in the variable prize winning device 32. The specific area switch 222 is a switch that determines that a game ball that has won the variable winning device 32 in the big hit state has entered a specific area (an area for determining whether or not to continue the big hit state), and the count switch 223 displays the winning ball. It is a switch to count.

The display control device 45 includes a CPU 521, a ROM (program ROM) 522, a work RAM 523, a video RAM 524, a character ROM 525, an image controller 526, an input port 527, two output ports 528 and 529, and a bus. Lines 530 and 531 are provided. The output of the main controller 261 is connected to the input of the input port 527, and the CPU 521, ROM 522, work RAM 523, and image controller 526 are connected to the output of the input port 527 and one output port is connected via the bus line 530. 528 is connected. An accessory symbol display device 41 (display unit 43) and an audio lamp control device 262 are connected to the output of the output port 528. An output port 529 is connected to the image controller 526 via a bus line 531, and a large symbol display device 42, which is a liquid crystal display device, is connected to the output of the output port 529.

  The CPU 521 of the display control device 45 controls the display of the large symbol display device 42 and the small symbol display device 41 based on the display command transmitted from the main control device 261. The ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 temporarily stores work data and flags used when the CPU 521 executes various programs.

It is displayed on the display device 42.

  The power supply unit 313 includes a power supply unit 541 for supplying power to each part of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch connected to the RAM erase switch 323. A circuit 543. 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 an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like. Then, 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.

  The power failure monitoring circuit 542 is a circuit for outputting 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 processing (NMI interrupt processing in FIG. 30).

  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 for taking in the switch signal of the RAM erase switch 323 and clearing 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

  By the way, the large symbol display device (liquid crystal display device) 42 has three symbol rows of left, middle, and right, and the symbols (large symbols) are variably displayed for each symbol row. In the present embodiment, large symbols are configured so as to be given numbers “0” to “9”, respectively, and large symbols are displayed in ascending or descending order of numbers to form a series of symbol strings. The large symbols are displayed in a variable manner from top to bottom with periodicity.

  In such a case, in the left symbol row, the big symbol symbols are displayed in descending order (in the order in which the attached numbers decrease), and in the middle symbol column and the right symbol column, the large symbol symbols are also in ascending order (in which the attached numbers increase). Is displayed. Then, the variable display stops in the order of the left symbol sequence → the right symbol sequence → the middle symbol sequence, and at the time of the stoppage, the large symbol symbol is a combination of the big symbol symbols on the large symbol display device 42 (in this embodiment, the same large symbol symbol) If it is arranged in combination, a special game video is displayed as a jackpot (a jackpot state is started).

  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) of the large symbol display device 42, setting of symbol display, and the like using various counter information during the game. Specifically, 22, the jackpot random number counter C1 used for the jackpot lottery of the big game symbol display device 42, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the big game symbol display device 42, and the big game symbol display device 42 Reach random number counter C3 used for reach lottery when the value fluctuates out, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, and variation type counter used for variation pattern selection of large symbol display device 42 CS1, CS2, and left, middle, and right outliers used to set the left, middle, and right outliers Counter CL, CM, has been with the use of the CR.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. 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. In addition, the RAM 503 is provided with a holding ball storage area including one execution area and four holding areas (holding first to fourth holding areas). The values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are stored in time series in accordance with the winning histories of the game balls.

  In detail, each of the counters is configured such that the jackpot random number counter C1 is incremented one by one within a range of, for example, 0 to 676, and returns to 0 after reaching the maximum value (that is, 676). In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot 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. The big hit random number counter C1 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 33. The number of random number values that are jackpots is set at two times, low probability and high probability. In this embodiment, the number of random numbers that are jackpots at low probability is 2, and the value is “337, 673”, the number of random number values that are jackpots at a high probability is 10, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means a state where the jackpot is won by a predetermined probability variation pattern and the subsequent jackpot probability is increased as added value, that is, the time of so-called probability change, and the normal time (low probability) is such It is said that it is not in a certain state.

  The jackpot symbol counter C2 determines a symbol when the fluctuation of the large symbol display device 42 is stopped at the time of a jackpot. In the present embodiment, the big symbol symbol display device 42 has 10 types of large symbol symbols set. 10 (0-9) counter values are prepared. In other words, the jackpot symbol counter C2 is configured so that 1 is added in order within the range of 0 to 9, and after reaching the maximum value (that is, 9), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 33.

  Further, the reach random number counter C3 is configured to increment one by one within a range of 0 to 238, for example, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. Note that the reach lottery may be set individually according to the state of the lottery probability of the large symbol display device 42, the number of starting and holding balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 33.

  Further, one of the two variation type counters CS1 and CS2 is incremented by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. For example, the other variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0. 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”. The first variation type counter CS1 determines the reach type of large symbols such as so-called normal reach, super reach, premium reach, and other general symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (the book) In the embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, 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 similarly by combining the first variation type counter CS1 and the stop symbol.

  The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in 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 large symbol by the large symbol display device 42.

  The left, middle and right off symbol counters CL, CM, CR are the stop symbols for the left row large symbol symbol, the middle row large symbol symbol, and the right column large symbol symbol when the large symbol display device 42 is out of the lottery lottery. Since each of the 10 large symbols is displayed in each column, 10 counter values (0 to 9) are prepared for each. The stop symbol of the left 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 right 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 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, 10 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated in the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach other than the front / rear symbol buffer of the RAM 503, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the start of the variation of the large symbol, the buffer value of any one of the front / rear reach symbol buffer, the reach symbol buffer other than front / rear out, and the completely out symbol buffer is acquired according to the value of the reach random number counter C3. .

  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 reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case.

  Although not shown, a small symbol random number counter is used for the lottery of the small symbol display device 41. The accessory symbol random number counter is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The accessory symbol random number counter is updated periodically (once every timer interruption in the present embodiment), and is acquired when the game ball passes through the accessory outlet 34 on either the left or right side. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and a stop to the NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by signal input. 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. 28 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. 28, first, in step S601, various winning switch reading processes are 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.

  Thereafter, in step S602, 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 this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In subsequent step S603, the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 9, and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S604, a start winning process associated with winning the big game mouth 33 is executed. This start winning process will be described with reference to the flowchart of FIG. 29. In step S701, whether or not the game ball has won the big game mouth 33 is determined based on the detection information of the start opening switch 224. When it is determined that the game ball has won the big game mouth 33, in the subsequent step S702, it is determined whether or not the number N of starting reserved balls of the big game symbol display device 42 is less than the upper limit value (4 in the present embodiment). To do. The process proceeds to step S703 on the condition that there is a winning at the big mouth 33 and the number of starting reserved balls N <4, and the number of starting reserved balls N is incremented by one.

  In the subsequent step S704, a random number related to the winning of the big symbol is acquired. Specifically, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area among the free storage areas of the reserved ball storage area of the RAM 503.

  Then, after the start winning process, the CPU 501 once ends the timer interruption process.

  FIG. 30 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 of FIG. The NMI interrupt processing in FIG. 30 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal SK1 is output, current is supplied from the power supply unit 541 so that the processing of the main control device 261 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt process of FIG. 30, first, in step S801, the used register is saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the information on occurrence of power interruption is set in the backup area 503a, and in step S804, a power interruption notification command indicating that the power has been interrupted is transmitted to another control device.

  In step S805, 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. In step S806, RAM access is prohibited. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The NMI interrupt process is also executed in the payout control device 311 in the same manner, and the state of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Similarly, the power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SK1 is output. 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. 30 is started. The contents are as described in FIG. 30 (however, the transmission of the power-off notification command in step S804 is excluded).

  FIG. 23 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 261. This main process is started upon reset when the power is turned on.

  First, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control device (sound lamp control device 262, payout control device 311 etc.) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311. In 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). In subsequent step S105, the information on occurrence of power interruption is set in the backup area 503a of the RAM 503. It is determined whether or not. In step S106, a RAM determination value is calculated. In subsequent step S107, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. Note that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, in the pachinko machine 10, when it is desired to return to the initial state when the power is turned on, for example, when the hall starts business, the power is turned on while the RAM erase switch 323 is pressed. 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, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal. Execute the process (process when power is restored). 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 sub-side control device 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. Further, in steps S112 and S113, the interrupt permission / non-permission is returned to the state before power-off, and then the address before power-off is returned.

  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 an outline, the processing of steps S201 to S207 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S209 and S210 is executed with the remaining time.

  In FIG. 24, first, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45 when the large symbol display device 42 displays the variation of the large symbol symbol. In addition, after the start of the movement of the big game symbol, each time the normal process is performed in the order of the variation pattern command → the left symbol sequence stop symbol command → the right symbol sequence stop symbol command → the middle symbol sequence stop symbol command The command is sent once every 4 msec), and the confirmation command is sent at the timing when the fluctuation time elapses. Further, the display control device 45 that has input the stop symbol command, the variation pattern command, the confirmation command, etc. determines the display mode of the large symbol display device 42 and the small symbol display device 41 based on the various commands, and the display mode Is displayed on the large symbol display device 42 and the small symbol display device 41.

  Next, in step S202, the variation type counters CS1 and CS2 are updated. 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 update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503. In subsequent step S203, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  The update process of each out symbol counter CL, CM, CR will be described in detail. As shown in FIG. 25, in step S301, it is determined whether or not it is time to update the out symbol counter CL in the left symbol row. In step S302, It is determined whether or not it is time to update the middle symbol row out of symbol counter CM. If the update timing of the left symbol sequence (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol sequence is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both steps S301 and S302 are NO), the process proceeds to step S305, and the out symbol counter CR of the right symbol sequence is updated. In updating the out-of-step symbol counters CL, CM, and CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 10 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR.

  According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  After that, in step S306, it is determined whether or not the combination of the updated outlier symbol counters CL, CM, and CR is a jackpot symbol combination. That is, it is determined whether or not the off symbol counters CL, CM, CR have values corresponding to the same symbol. If it is not a jackpot symbol combination, the process proceeds to step S307.

  In step S307, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a reach symbol combination. That is, it is determined whether or not the off symbol counter CL and the off symbol counter CR have values corresponding to the same symbol. If it is a reach combination, it is further determined in step S308 whether or not it is a front-rear reach. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S309, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear outreach symbol buffer of the RAM 503. When the out symbol counters CL, CM, CR are not a combination of front and rear outreach, that is, when the out symbol counters CL, CM, CR are a combination of reach other than out of front and rear, the process proceeds to step S310, and the out symbol at that time The combination of the counters CL, CM, and CR is stored in the reach symbol buffer except for the back and forth deviation of the RAM 503.

  If the combination is other than the reach symbol, the process proceeds to step S311 and the combination of the symbol symbol counters CL, CM, CR at that time is stored in the symbol symbol buffer of the RAM 503. In step S306, if the symbols are aligned on the left, middle, and right, that is, a combination of jackpot symbols, this processing is terminated without storing the off symbol counters CL, CM, CR in the buffer. To do.

  After the off symbol counter update process, in step S204 in FIG. 24, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a large symbol variation process for performing variation display of the large symbol on the large symbol display device 42 is executed. By this big game symbol variation processing, jackpot determination, large symbol variation pattern setting, and the like are performed. However, details of the large symbol variation process will be described later.

  Thereafter, in step S206, a large opening opening / closing process for opening or closing the large opening of the variable prize winning device 32 is executed in the case of a big hit state. That is, the large opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the large opening has elapsed or whether a predetermined number of game balls have been won in the large opening. And when either of these conditions is satisfied, the large opening is closed. At this time, continuous opening of the large opening is permitted on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, the accessory symbol display device 41 performs display control of the accessory symbol. Briefly, on the condition that the game ball has passed through the accessory port 34, an accessory symbol random number counter is acquired each time and the accessory symbol lottery is performed on the display unit 43 of the accessory symbol display device 41. When the small symbol is hit, the big mouth 33 is opened for a predetermined time. Although not described here, the small symbol random number counter is also updated by the timer interruption process shown in FIG. 28, like the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3.

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. Then, the random number initial value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, 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 this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503.

  In step S210, update of the variation type counters CS1 and CS2 is executed (same as 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 S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. .

  Next, the large symbol variation process of step S205 will be described with reference to the flowchart of FIG.

  In FIG. 26, in step S401, it is determined whether or not it is a big hit now. Note that the jackpot includes a special game displayed on the big symbol display device 42 and a predetermined time after the special game is ended. In a succeeding step S402, it is determined whether or not the large symbol display device 42 is displaying the variation of the large symbol. If the big symbol is not being displayed and the variation of the big symbol is not being displayed, the process proceeds to step S403 to determine whether or not the number N of starting reserved balls of the large symbol display device 42 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 it is neither a big hit nor a large symbol variation display, and if the number of starting reserved balls N> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of starting reserved balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, a change start process is executed. Here, the details of the variation start processing will be described using the flowchart of FIG. 27. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Specifically, whether or not the jackpot is determined based on the relationship between the jackpot random number counter value and the mode at that time, as described above, among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, "337, “673” is the winning value, and “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” is the winning value when the probability is high.

  If it is determined that the game is a jackpot, in step S502, a table corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (value of the jackpot symbol counter C2). And a symbol representing the correspondence between the symbol and the symbol), and the symbol is set as a stop symbol command. At this time, any of the 10 jackpot symbols corresponding to the numerical values 0 to 9 of the jackpot symbol counter C2 is set in the stop symbol command. When these jackpot symbols are gathered with a predetermined specific symbol, the state changes to the probability variation state, but when the symbols are not specific symbols (non-specific symbols), the probability variation state is not reached.

  Next, in step S503, 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 confirmed, and the reach type of a large symbol such as normal reach, super reach, premium reach, etc. is determined based on the value of the first variation type counter CS1. And other rough symbol variation modes, and the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after occurrence of reach based on the value of the second variation type counter CS2 (in other words, variation More detailed symbol variation mode is determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like.

  On the other hand, if it is determined in step S501 that it is not a big hit, it is determined in step S504 whether or not a reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area. If the reach has occurred, it is further determined in step S505 whether the reach is out of front or back based on the value of the reach random number counter C3. In the present embodiment, the value of the reach random number counter C3 is any one of 0 to 238, of which “0, 1” corresponds to the out-of-front reach and “2-21” corresponds to the reach other than the back-and-forth out- “22 to 238” corresponds to no reach (complete detachment).

  If front / rear out of reach has occurred, the process proceeds to step S506, and the left, middle, and right out of symbol counters CL, CM, CR stored in the front / rear out of reach symbol buffer of the RAM 503 are set as stop symbol commands.

  Thereafter, in step S507, a variation pattern at the time of front / rear out of reach is determined, and the variation pattern is set as a variation pattern command. At this time, as in step S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. Etc., until the reach stop type (in this embodiment, the middle symbol) is stopped after the occurrence of the reach based on the value of the second variation type counter CS2. A more detailed symbol variation mode such as the elapsed time (in other words, the number of variation symbols) is determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like.

  If it is determined in step S505 that the reach is not front / rear out of reach (reach other than front / rear out), the process proceeds to step S508, and each of the left, middle, and right stored in the reach symbol buffer other than front / rear out of RAM 503 is stored. Each value of the off symbol counters CL, CM, CR is set in the stop symbol command. Also, in step S509, a fluctuation pattern at the time of reach other than front / rear deviation is determined, and the fluctuation pattern is set as a fluctuation pattern command. At this time, 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, as in step S503 and the like.

  If it is neither big hit nor reach, the process proceeds to step S510, and the left, middle, and right out symbol counters CL, CM, and CR stored in the complete out symbol buffer of the RAM 503 are set as stop symbol commands. In step S511, the fluctuation pattern at the time of complete deviation is determined, and the fluctuation pattern is set in the fluctuation pattern command. At this time, since the reach does not occur, the player's interest is reduced, and various symbol variation modes are not required. Therefore, in the present embodiment, in step S511, the symbol variation mode is determined using only the first variation type counter CS1 (that is, without using the second variation type counter CS2). As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, when the reach occurs, and when the reach does not occur, this processing ends.

  Returning to the description of FIG. 26, if step S402 is YES, that is, if a large symbol design is being displayed, the process proceeds to step S407, where it is determined whether the variation time has elapsed. At this time, the variation time of the large symbol is determined according to the variation pattern of the large symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a confirmation command is set in order to confirm the stop of fluctuation, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 31 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

  First, in step S901, 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 S902, the process waits until a payout permission command transmitted from main controller 261 is received. When the payout permission command is received, the process advances to step S903 to permit RAM access, and in step S904, an external interrupt vector is set.

  Thereafter, a data backup process is executed for the RAM 513 in the CPU 511. That is, in step S905, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON). In subsequent step S906, the information on occurrence of power interruption is set in the backup area 513a of the RAM 513. It is determined whether or not. In step S907, a RAM determination value is calculated. In subsequent step S908, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. It should be noted that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S915, etc.). Similarly, when the occurrence information of power interruption is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (step S915 or the like). That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal. Execute the process (process when power is restored). That is, in step S909, the stack pointer before the power interruption is restored, and in step S910, the information on the occurrence of the power interruption is cleared. In step S911, CPU peripheral devices are initialized, and in step S912, the used registers are restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the interruption permission / non-permission is returned to the state before the power interruption, and then the address before the power interruption is returned.

  Next, the flow of the payout control process will be described with reference to the flowchart of FIG.

  In FIG. 32, in step S1001, a command from the main controller 261 is acquired, and the total number of winning balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 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 S1005, setting of a tank ball absence state or a tank ball absence release 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 when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration.

  Thereafter, in step S1006, the presence / absence of a state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified.

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not in a payout-disabled state and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009 and a prize ball control process (described later). FIG. 33) is started. Further, if the prize ball cannot be paid out or the total number of prize balls is 0 (YES in any one of steps S1007 and S1008), the process proceeds to a lending payout process.

  Thereafter, in steps S1010 to S1012, a rental ball payout process is executed. In this case, if it is not possible to pay out the rent and if a rent-out request from the card unit has been received (NO in step S1010, YES in S1011), the process proceeds to step S1012 and a renting control process (described later). FIG. 34) is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), the subsequent ball removal process is executed.

  In step S1013, the payout motor 368a is driven to execute the ball removal process on the condition that the state return switch 321 is checked to check that the ball removal is not disabled and the ball removal operation is not started. In subsequent step S1014, control of vibrator 360 (vibration motor control) is executed on condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  Here, in the prize ball control process shown in FIG. 33, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process in FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to step S1104, and whether or not the game ball is normally counted is determined based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1105 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then returns to the payout control process of FIG.

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, the stop process of the payout motor 358a is executed in step S1107, and then the process returns to the payout control process of FIG.

  In the ball lending control process shown in FIG. 34, in step S1201, the payout motor 358a is driven to pay out a lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1203, where the payout motor 358a is driven to execute a retry process and a stop process of the payout motor 358a, and then the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process advances to step S1204 to determine whether or not the game ball is normally counted based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1205 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

  If the game ball count is normal, the process proceeds to step S1206, where it is determined whether or not the game ball count by the payout count switch has reached a predetermined number of rented balls (25) and the payout is completed. If the payout has been completed, a stop process of the payout motor 358a is executed in step S1207, and then the process returns to the payout control process in FIG.

  As described above in detail, in the present embodiment, the cover member 402 (side wall portion 422) is provided so as to surround the outer peripheral edge of the base plate 404. The game ball flowing down along the game board surface hits the side wall portion 422 provided so as to be substantially orthogonal to the game board surface. Then, the game ball is not directed in front of the game board surface but is directed upward or to the side of the general winning award 31. Therefore, it is possible to suppress a situation in which the game ball flowing down on the game board surface collides with the end portion of the base plate 404 and jumps forward vigorously. Therefore, for example, the risk of damage to the glass 137 caused by the splashed game ball colliding with the glass 137, noise, and the like can be reduced.

  Further, since the distance between the front surface of the cover member 402 and the rear surface of the glass 137 is shorter than the diameter of the game ball, the game ball hits the upper surface of the side wall portion 422. Therefore, the possibility that the game ball collides with the front end portion of the cover member 402 (side wall portion 422) and jumps forward vigorously can be suppressed, and the above-described effects can be further ensured. Further, conventionally, since the base plate 404 is provided so as to protrude forward from the surface of the game board, the front and rear width of the area where the game ball can flow down on the front side of the base plate 404 (game area) is narrowed. There was a risk of getting caught. In this respect, in the present embodiment, since the game ball is configured so as not to pass through the front of the base member, it is possible to suppress a problem that the game ball is caught.

  Further, since the game ball cannot pass in front of the base plate 404 by the cover member 402 (side wall portion 422), it is not necessary to make the foremost part such as a wood screw flush with the front end surface of the base plate 404. The configuration of the base plate 404 can be simplified.

  Further, the front wall portion 421 makes the front screw hole 408 and the wood screw attached to the front screw hole 408 invisible from the player side. As a result, the appearance quality can be prevented from deteriorating. Furthermore, since the front wall portion 421 and the side wall portion 422 are integrally formed, the rigidity of the cover member 402 can be further increased.

  In addition, since the locking portion 424 is provided on the back surface of the front wall portion 421, the locking portion 424 is not visible from the player side. In addition, the protruding portion 409 corresponding to the locking portion 424 is also not visible from the player side. Therefore, it is possible to suppress a decrease in appearance quality.

  In addition, since the communication portion 407 is formed at the upper end edge of the base plate 404, the game ball can enter the ball receiving member 406 without straddling the base plate 404. Accordingly, the game ball collides with the base plate 404 and is repelled forward, for example, and the ball is strongly collided with a low rigidity portion of the ball receiving member 406, and the deterioration of the ball receiving member 406 is accelerated. Problems such as being unable to enter the ball receiving member 406 can be reduced.

  In addition, the upper end surface of the side wall portion 422 is configured to incline downward toward the left and right end portions, and the possibility that the game ball stays on the upper end surface of the side wall portion 422 can be suppressed.

  Further, since the front wall portion 421 is configured to close the front portion of the ball receiving member 406, it is not necessary to provide a portion for closing the front opening in the ball receiving member 406 itself, and the configuration of the ball receiving member 406 is configured. It can be simplified. In addition, it is possible to manufacture the mold relatively easily without any difficulty, and to give variations in shape with respect to the general winning opening 31.

  Furthermore, since the projecting portion 409 (the locking hole 410) and the locking portion 424 (the claw 423) are locked, the prize winning opening main body 401 and the cover member 402 are attached and fixed. Such attachment work can be performed relatively easily and quickly.

  Further, since the locking hole 410 is configured to penetrate substantially horizontally in the left-right direction, the locking direction of the locking portion 424 that locks the protruding portion 409 (locking hole 410) is substantially horizontal. Become. In general, since the game ball flows down from above, the game ball may collide with the upper surface of the side wall portion 422 with a predetermined energy. In this respect, in this example, since the locking direction is substantially horizontal, even if stress is applied from the vertical direction, it is difficult to receive stress in the locking direction, and thus in the locking release direction. Therefore, problems such as the cover member 402 being removed due to the collision of the game balls can be suppressed, and the attachment state of the cover member 402 can be more reliably maintained.

  In addition, the presence of the insertion hole 425 allows the cover member 402 to be removed from the winning opening main body 401 relatively easily and quickly. For example, when only the maintenance of the cover member 402 is desired to be performed in the general winning opening 31 that is attached to the game board 30, only the cover member 402 can be removed for maintenance. In addition, since the insertion hole 425 is provided in the side wall part 422, the insertion hole 425 becomes invisible or difficult to visually recognize from the player side, and deterioration in appearance quality can be suppressed.

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

  (A) In the above embodiment, the cover member 402 (side wall portion 422) is provided so as to cover the base plate 404. However, the present invention is not particularly limited to this configuration. It is only necessary to restrict at least collision with the upper surface and jumping forward of the base plate 404. For example, the side wall 422 may be provided so as to cover the upper surface of the base plate 404.

[Appendix]
The technical idea that can be grasped from the above embodiment will be described below.

Means 1. A game board with a game area where game balls can flow down on the front side;
A gaming machine comprising: a base member that comes into contact with and fixed to the gaming board; and a gaming member that includes a protruding member provided so as to protrude forward of the base member,
The gaming member includes a saddle member extending forward from at least the upper surface of the base member so as to be orthogonal to the gaming board surface,
A gaming machine configured to restrict a game ball from colliding with at least an upper surface of the base member and jumping forward of the base member.

  According to the means 1, the game ball flowing down along the game board surface hits the saddle member provided so as to be orthogonal to the game board surface. Then, the game ball is directed upward or to the side of the game member rather than in front of the game board surface (a direction from the front surface of the game board toward the game area). Therefore, it is possible to suppress a situation in which a game ball that has flowed down at least from above collides with the upper surface of the base member and jumps forward vigorously. Therefore, for example, it is possible to reduce the risk of damage to the transparent member due to the splashed game ball colliding with the transparent member (glass) provided on the front side of the game board surface, noise, and the like.

  Further, for example, when the gap between the front part of the bowl member and the transparent member is configured to be narrower than the diameter of the game ball, the above-described operational effect is more reliable. Moreover, the structure that the space | interval of the front part of a gutter member and a transparent member becomes narrower than the diameter of a game ball can suppress the malfunction that a game ball is pinched | interposed between a gutter member and a transparent member.

  The phrase “extending forward from the upper surface so as to be orthogonal to the game board surface” means that the lower surface of the saddle member is configured to contact the upper surface of the base member, or the saddle member This means that the game board surface side (back surface) is configured to come into contact with the game area side surface (front surface) of the base member. In other words, it is only necessary to restrict the game ball from colliding with at least the upper surface of the base member and jumping to the front of the base member. Further, the gaming member includes a heel member extending forward from the front surface of the base member so as to be orthogonal to the game board surface, and the upper surface of the heel member and the upper surface of the base member are configured to be flush with each other. At the same time, it may be configured to restrict the game ball from colliding with at least the upper surface of the base member and jumping forward of the base member. Moreover, the said base member is good also as providing the eaves member extended ahead so that it may orthogonally cross the said game board surface from an outer peripheral edge. In that case, not only the game ball flowing down from the upper side toward the base member but also the game ball moving toward the base member from the side and lower side may collide with the base member and jump forward. Can be suppressed, and the above-described effects can be made more remarkable. Further, “being orthogonal to the game board surface” may be “being orthogonal to the front surface of the base member”. In addition, the projecting member may be capable of (uniquely) guiding the game ball flowing down from above (uniquely) (the same applies to each means).

Mean 2. A game board with a game area where game balls can flow down on the front side;

The upper end portion of the protruding member and the end portion of the extending member may be configured to contact each other. In that case, the game ball inserted through the hole can be reliably guided to the protrusion. Further, the saddle member may extend forward in the direction orthogonal to the game board surface so as to surround the outer peripheral edge of the base member. In that case, not only the game ball flowing down from the upper side toward the base member but also the game ball moving from the side and lower side toward the base member may collide with the base member and jump forward. Can be suppressed. Furthermore, at least the upper end surface of the flange member may be configured to be inclined downward toward the left and right end portions. In that case, the possibility that the game ball may stay on the upper end surface of the saddle member can be suppressed. Moreover, the said communicating hole is good also as being formed in the outer periphery edge of the said base member. In that case, for example, the game ball can enter the game member that can enter the game ball without straddling the base member. Therefore, the game ball collides with the base member, for example, it is repelled forward, etc., and it collides with the projecting member vigorously, so that the deterioration of the projecting member is accelerated or the game ball cannot enter the game member. Can be reduced.

  According to the means 8, the attachment state of the base member to the game board can be kept stronger. Moreover, it can be comprised so that it may become difficult for a game ball to pass the front of an attachment hole and an attachment means with a saddle member, or to pass. In that case, it is not necessary to make the foremost part of the attachment means flush with the front end surface of the base member, and the configuration of the base member can be simplified. In addition, when the game ball is configured to be unable to pass in front of the mounting hole by, for example, configuring the heel member to extend forward from the side end portion of the base member or the outer peripheral edge of the base member, such an effect is further increased. Can be prominent.

  Means 9. 9. The gaming machine according to claim 8, wherein the saddle member includes a saddle portion extending forward so as to be orthogonal to the game board surface, and a concealing portion that conceals at least the mounting hole.

  According to the means 9, it is possible to make the attachment hole and the attachment means invisible or difficult to see from the player side. As a result, deterioration in appearance quality can be suppressed. In addition, the above-described saddle member (having the concealed portion) can be configured relatively easily. For example, the concealed portion is directed from the front edge of the saddle portion toward the mounting hole so as to be parallel to the game board surface. It may be configured to extend. Furthermore, since the hidden portion is formed integrally with the collar portion, the rigidity of the collar member can be further increased. The concealed portion may be configured to cover the base member on the parallel projection plane from the front surface in the vertical direction of the base member surface, or to make the base member invisible from the player side. Good. In that case, the above effect can be further ensured. Moreover, it is good also as information being attached | subjected to the hidden part front surface.
