  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 a pachinko machine 10, and FIG. 2 shows a lower plate unit in which a front frame set 14 serving as a front door is opened with respect to an outer frame 11 described later and an inner frame 12 serving as a support frame. It is a perspective view showing the state where 13 was removed. However, in FIG. 2, for the sake of convenience, a configuration in a game area on the surface of the game board 30 to be described later is shown in blank.

  As shown in FIG. 6, 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 at one side of the outer frame 11 so as to be openable and closable. . 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 position where the handle 18 described later) is viewed from the front of the pachinko machine 10, and the inner frame is centered on the opening / closing axis. 12 can be opened to the front side. 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.

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 formed 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 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 portion 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. The upper plate 19 is integrally formed with the glass frame portion that supports the glass 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 described later, the front frame set 14 (glass frame Part) can be ensured. 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 includes a general winning port 31, a special device 32, a variable display unit 35, a start winning unit 461, a large opening unit 462, and the like arranged in through holes formed by router processing. It is attached from the side with wood screws. A normal symbol operating port 33 is provided above the central portion of the special device 32, and a specific winning port 400 is provided immediately below the normal symbol operating port 33. In addition, the game board 30 is provided with an out-port 36 so that game balls that have not entered the various prize-winning portions are guided through the out-port 36 toward a ball discharge path (not shown). It has become. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (functions) such as the windmill 27 are arranged.

  The variable display device unit 35 is provided with a normal symbol display device 42 that variably displays a normal symbol as identification information with a winning at the normal symbol operating port 33 as a trigger.

  The normal 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 normal 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 normal symbol display device 42 so as to be scrolled for each symbol row. In the present embodiment, the normal 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 normal symbol display device 42.

  The special winning opening 400 of the special device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which the game ball is easy to win in the case of “winning”. More specifically, it is a necessary condition that when the game ball wins the normal symbol operating port 33, the normal symbol display device 42 displays the symbols in a variable manner, and the confirmed symbol after the stop is a combination of specific symbols set in advance. Will be open. When the confirmed symbol is a combination of specific symbols set in advance, the symbol is opened for a predetermined time (4.0 seconds or 5.8 seconds in this embodiment). When a new game ball wins the normal symbol operating port 33 during the symbol variation display of the normal symbol display device 42, the corresponding symbol variation display is performed after the symbol variation display performed at that time ends. It is the composition that is called. That is, the symbol variation display is waited (held, stored). 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 suspensions may be set to 8 in order to wait for 8 symbol fluctuation displays. The hold lamp 46 may be configured to be displayed on a part of the normal symbol display device 42.

  The special winning opening 400 of the special device 32 is kept open for a predetermined time when the confirmed symbol is a combination of specific symbols set in advance. At this time, the game ball that has entered is stopped at the stopping portion. A structure in which game balls can be stopped at the stop portion, and when a required number of game balls enter the specific winning opening 400, one of the game balls passes through the special device operation area. It has become. Then, on condition that the game ball passes through the special device operation area, a state (game state) for transition to the special game state is generated. The configuration of the special device 32 will be described later.

  Further, a start winning unit 461 is provided on the right side of the variable display device unit 35, and a large opening unit 462 is provided below the start winning unit 461.

  The start winning unit 461 is for operating the large opening unit 462, and includes a rotating body 464 housed inside the outer frame portion and a special winning port 465 at the lower portion of the outer frame portion.

  The outer frame portion is intermittent at its upper end. The rotating body 464 has a ball receiving portion 466 as a holding portion and is rotatable. The rotating body 464 normally rotates in a predetermined direction (for example, clockwise) at a constant speed (a period of about 5 seconds in the present embodiment). When the game ball is guided to the upper end portion of the start winning unit 461 by a nail or the like, if the ball receiving portion 466 is not directed upward, the game ball is stopped at the intermittent portion of the outer frame portion, When the portion 466 is directed upward, the game ball enters the ball receiving portion 466.

  Then, the game ball is carried downward along with the rotation of the rotating body 464, and when the ball receiving portion 466 reaches the position of the special prize opening 465, the game ball wins the special prize opening 465. When the game ball is awarded to the special prize opening 465, when the state for shifting to the special game state is generated as described above, the large opening mouth unit 462 operates. Note that the game ball that has won the special prize opening 465 is detected by a prize detection mechanism described later, and then discharged to a ball discharge unit (not shown). In normal times, the rotation cycle time of the rotating body 464 is substantially the same as a single opening operation time of the large opening unit 462 described later. This is to suppress a problem that, while the large opening unit 462 is being opened, a transition is made to the next round despite being in the middle of the round.

  The large opening unit 462 includes a large opening 471 and an electric accessory 472 that opens or closes the large opening 471. The electric accessory 472 is pivotally supported so that it can be opened and closed to the left and right, and is driven to open and close by a solenoid provided on the back side of the large opening 471. The electric accessory 472 is in an open state for a predetermined opening time (about 5 seconds in the present embodiment) with respect to one winning at the special winning opening 465 of the game ball. A game ball that has won a prize in the large opening 471 is detected by a prize detection mechanism described later, and then discharged to a ball discharge unit (not shown).

  As described above, when a state for shifting to the special game state occurs, a special game state in which the large opening unit 462 is activated by entering the start winning unit 461 is entered. In this special game state, the large opening unit 462 operates for a predetermined round by entering the start winning unit 461, and it becomes possible to acquire more game balls than usual.

  In addition, a rail unit 50 is attached to the game board 30 as a rail member for guiding the game ball launched from the game ball launching device to the upper part of the game board 30, and the game board 30 is launched as the handle 18 rotates. The played game balls 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 is attached to the front end 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 NJ are inserted into the plurality of through holes formed in the flange 56. Thus, the rail unit 50 is 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 the figure) such as certificate stamps, in order to secure this attachment space. 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.

  By extending the game area in the left-right direction, the wind turbine 27, a plurality of nails (guide nails for guiding the game ball to the center), and other accessories can be arranged in various ways. The behavior of the game ball in the game areas on the left and right sides of 35 can be made more interesting. Further, since the game area is also expanded in the vertical direction, the windmill 27, a plurality of nails and other accessories can be arranged in various ways, and the behavior of the game ball in the vertical direction in the game area is further enhanced. It can be 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. In this case, in particular, 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) in the left-right direction 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 launched from the game ball launching device does not reach the return ball prevention member and returns as a foul ball in the guide rail, the foul ball passes through the foul ball passage 63 to the lower plate 15. 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. As a result, all of the foul balls are reliably guided to the foul ball path 63, and interference between the foul balls and the game balls to be fired next is suppressed.

  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.

  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. 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 side 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 during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of hitting or predetermined reach. 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 winning lamp, and lights up or blinks when hitting to notify that it is hitting. 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 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. 12a (refer FIG. 3 etc.) is comprised. 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 a pair of front and rear glasses 137 having a rectangular shape are 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 open side on the front side 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 invaded through the gap between the front frame set 14 and the inner frame 12 to perform a fraudulent 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.

Conventionally, since a portion corresponding to the game ball distributing unit 245 is provided on the back pack unit 203 side, the back pack unit 203 is pushed through the ball discharge port (ball passage wall 69 in FIG. 2) reaching the upper plate 19. As a result, a gap is formed between the inner frame 12 and a portion corresponding to the game ball distributing unit 245, and an illegal act of inserting a wire or the like through the gap and operating the internal device has been considered. Therefore, in the pachinko machine 10, such illegal acts are prevented by providing the game ball distribution unit 245 on the inner frame 12 side and fixing the game ball distribution unit 245 by a fixing means. Further, the upper end surface of the game ball distributing unit 245 is formed in accordance with the height position where the lower end surface of the game board 30 is installed, and is devised so as not to prevent the game board 30 from being removed.

  In addition, a resin speaker box 246 is attached to the lower end of the inner frame 12 so as to surround the back of the speaker 249 installed toward the lower plate 15. Improvements are being made.

  Next, the first control board unit 201 will be described with reference to FIGS. 11 is a front view of the first control board unit 201, FIG. 12 is a perspective view of the unit 201, FIG. 13 is an exploded perspective view of the unit 201, and FIG. 14 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 includes a mounting base 251 having a substantially L shape, and the main control device 261 and the sound lamp control device 262 are mounted on the mounting base 251. Here, the main control device 261 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and various lotteries. A main board including a random number generator used, a clock pulse generation circuit used for time counting and synchronization, etc., and the main board is made of a transparent resin material or the like; ). The substrate box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected to each other by a sealing unit 264 (sealing means) so that the substrate box 263 is sealed.

  As the sealing unit 264 as the sealing means, any configuration can be applied as long as the box base and the box cover are connected so as not to be opened, but here, as shown in FIG. 11 and the like, five sealing members are connected. The box base and the box cover are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the board box 263 is left in the board box 263, it can be easily found that the illegal opening has been performed by looking at the board box 263.

  The voice lamp control device 262 is a voice lamp including, for example, a CPU that controls voice and lamp display in accordance with instructions from the main control device 261 (main board) or the display control device 45, and other ROM, RAM, various ports, and the like. The audio lamp control board is housed in a board box 265 made of a transparent resin material or the like. A power relay board 266 is mounted on the sound lamp control device 262, and power supplied from a power board described later is output to the display control device 45 and the sound lamp control device 262 via the power relay board 266. It is like that.

  The mounting base 251 is formed of a colored (for example, green, blue, etc.) resin material (for example, made of polycarbonate resin), and has two substrate mounting surfaces 252 and 253 that are flat on the surface. These substrate mounting surfaces 252 and 253 extend in a direction perpendicular to each other, and are formed with a step in the front-rear direction. However, the mounting base 251 may be a colorless transparent or translucent resin molded product.

  The main control device 261 (main substrate) is arranged in a landscape orientation on one substrate mounting surface 252 and the audio lamp control device 262 (audio lamp control substrate) is arranged in a portrait orientation on the other substrate mounting surface 253. It is arranged in the direction. In particular, the main control device 261 is disposed on the near side as viewed from the back of the pachinko machine 10, and the sound lamp control device 262 is disposed on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 261 and 262 are mounted in a state where the main controller 261 and the sound lamp controller 262 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with a part of them stacked one after the other. That is, as can be seen in FIG. 12 and the like, the main controller 261 is arranged in a state where a part thereof (about 1/3 in the present embodiment) is floated. Therefore, the sound lamp control device 262 can be expanded to an area overlapping with the main control device 261, and the enlargement of the control board can be dealt with satisfactorily. Also, each control device can be installed efficiently. In addition, when the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252, and the special device 32 and its electric wiring can be installed without difficulty.

  As shown in FIGS. 13 and 14, the board mounting surface 252 for the main board has horizontally elongated through holes 254 at two positions on the left and right. Correspondingly, the substrate box 263 of the main control device 261 is provided with rotational fixing tools 267 at two places on the left and right sides of the back surface thereof. When the main controller 261 is mounted on the board mounting surface 252, the fixing tool 267 is passed through the through hole 254 of the board mounting surface 252, and the fixing tool 267 is rotated in this state to lock the main control apparatus 261. The Therefore, even if the main control device 261 is arranged in a state where it floats as described above, inconveniences such as dropping off of the main control device 261 can be avoided. In addition, since the main control device 261 cannot be removed unless the fixture 267 is unlocked from the back side of the first control board unit 201 (board mounting surface 252), it is expected to have a deterrent effect against illegal acts such as board removal. it can. A grid-like rib 255 is provided on the back surface of the substrate mounting surface 252 for the main substrate.

  The mounting base 251 is provided with a pair of upper and lower support shafts 256 on the left end surface in FIG. 11 and the like.

  The payout control device 311, the firing control device 312, the power supply device 313, and the card unit connection substrate 314 are respectively configured to be accommodated in substrate boxes 315, 316, 317, and 318 made of a transparent resin material or the like. In particular, in the dispensing control device 311, similarly to the main control device 261 described above, the box base and the box cover constituting the substrate box 315 (encapsulating means) are connected by the sealing unit 319 (sealing means) so that they cannot be opened. Thus, the substrate box 315 is sealed.

  The payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball jam in the payout motor unit, the payout motor is rotated forward and reverse so that the ball jam is eliminated (return to the normal state). It has become.

  The power supply device 313 is provided with a RAM erase switch 323. This pachinko machine 10 has a backup function, so that even if a power failure occurs, it maintains the state at the time of a power failure, and can be restored to the state at the time of a power failure when returning from a power failure (power recovery) It has become. Therefore, if the power is turned off in the normal procedure (for example, when the hall is closed), the state before the power is turned off is stored. If you want to return to the initial state when the power is turned on, turn on the power while holding down the RAM erase switch 323. We are going to throw it in.

  The mounting base 301 is made of, for example, a colorless and transparent resin molded product, and a flat substrate mounting surface 302 is provided on the surface thereof.

  Next, the configuration of the special device 32 will be described with reference to FIGS. The present embodiment is characterized by the stopping portion of the special device 32. Therefore, the structure of the stop part in the special apparatus 32 is demonstrated in detail here.

  21 is a front view of the special device 32, and FIG. 22 is a cross-sectional view taken along line AA of FIG.

  The special device 32 has a normal symbol operating port 33 at the uppermost part in the center. A special winning opening 400 is provided immediately below the normal symbol operating port 33, and an open state in which a game ball can be entered and an inability to enter the game ball by an electric accessory 402 provided on both left and right sides. It can change to the closed state. A plate-like front decoration member 401 is provided at the center of the front side of the special device 32. The front decoration member 401 has a transparent resin window 401a, and a player can visually recognize a stop portion of a game ball, which will be described later.

  The electric accessory 402 is driven to open and close by a specific prize opening solenoid 421. Specifically, when the specific prize opening solenoid 421 is energized, the movable member 422 moves to the front side and pushes the electric accessory 402 left and right. Further, a count switch 403 for counting winning balls is provided on the back side of the front decorative member 401.

  The special device 32 of the present embodiment is configured as a stopping device having a stopping portion. However, as shown in FIGS. 23 and 24, a ball receiving portion 404a having a U-shaped cross section is provided behind the front decorative member 401. , 404b.

  In the present embodiment, a first stoppable state and a second stoppable state are prepared as the stoppable states of the ball receiving portions 404a and 404b. In the 1st stoppage possible state, it arrange | positions so that the opening part may face inward upper direction. Accordingly, the first game ball that has entered the specific winning opening 400 is stopped at one of the ball receiving portions 404a or 404b. Next, the second game ball is stopped at the other ball receiving portion 404b or 404a. Then, the third game ball is stopped so as to be stacked in the middle of the two game balls stopped at the ball receiving portions 404a and 404b. On the other hand, in the 2nd stop possible state, it arrange | positions so that the opening part may face right above. In this case, the first game ball that has entered the specific winning opening 400 is supported by the inner ends of the ball receiving portions 404a and 404b and is stopped at the central portion.

  In addition, in the first stoppable state, when the entry of three game balls is detected, the specific winning opening 400 changes to the closed state, but the fourth and subsequent game balls entered before that time. Is configured to be discharged to the back side of the game board 30 from a discharge passage 406 formed on the back side of the central portion. This is as indicated by the symbol J in FIGS. In addition, in the second stoppable state, when the entry of one game ball is detected, the specific winning opening 400 changes to the closed state (FIG. 24 shows the closed state), but before that The second and subsequent game balls that have entered the ball are discharged to the back side of the game board 30 from a discharge passage 406 formed on the back side of the central portion. Therefore, the stopping part of this embodiment has a configuration capable of stopping three or one game ball.

  As shown in FIG. 25, the ball receiving portions 404a and 404b are connected to one end of shafts 414a and 414b extending in the front-rear direction. The other ends of the shafts 414a and 414b are connected to the cranks 413a and 413b. The cranks 413a and 413b are supported so as to be rotatable about the shafts 414a and 414b as center axes, and the end portions arranged on the inner side of the shafts 414a and 414b are supported by the motor hook 412. Yes. The motor hook 412 moves in the vertical direction in conjunction with the stopping motor 411. A rotary encoder and a photo sensor (not shown) are provided below the stopping motor 411 so that the vertical position of the motor hook 412 can be adjusted.

  With such a configuration, in the first stoppable state, as shown in FIG. 25 (a), the ball receiving portions 404a and 404b are arranged such that the opening portions thereof face inward and upward. In this state, it is possible to stop three game balls. Further, in the second stoppable state, as shown in FIG. 25 (b), the ball receiving portions 404a and 404b are arranged so that the opening portions thereof face directly upward. In this state, it is possible to stop one game ball. When the motor hook 412 moves upward as indicated by the symbol K in FIG. 25C from such a first or second stoppage possible state, the shafts 414a and 414b rotate by the action of the cranks 413a and 413b, respectively. (Denoted by symbols L and M). Thereby, the ball receiving portions 404a and 404b are arranged so that the opening portions thereof face outward and upward. Specifically, the ball receivers 404a and 404b rotate to a position where a gap slightly larger than the diameter of the game ball is formed between the ball receivers 404a and 404b.

  As shown in FIG. 26, discharge paths 405a and 405b are formed on the inner side of the ball receiving portions 404a and 404b in correspondence with the rotational positions of the ball receiving portions 404a and 404b. Further, a special device operation area 407 is formed between the discharge paths 405a and 405b. Therefore, when the stoppage state is changed from the first stoppable state, the two game balls stopped in the ball receiving portions 404a and 404b pass through the discharge paths 405a and 405b and are discharged to the back side of the game board 30. (Denoted by the symbol N). On the other hand, since the game ball to be supported moves outward by the rotation of the ball receiving portions 404a and 404b, the third game ball falls downward and passes through the special device operation area 407. As indicated by the symbol O. In addition, as shown in FIG. 27, when the second stoppable state is set to the stop release state, the first game ball moves downward and the ball receiving portions 404a and 404b themselves move downward, so that the special Pass through the device operating area 407. As indicated by the symbol O.

  Therefore, in the present embodiment, three game balls are stopped in the first stoppable state, and one game ball is stopped in the second stoppable state. The game ball will pass through. Note that a special device switch 408 is provided in the special device operation area 407 so that the passage of the game ball can be detected.

Specifically, it is detected by a sensor signal that a firing permission signal is output from the payout control device 311, the player is touching the handle 18, and a firing stop switch for stopping the firing. On the condition that is not operated, the launch motor 229 is driven, and a game ball is launched with an intensity corresponding to the operation amount of the handle 18 (see FIG. 9).

  The display control device 45 controls the normal symbol variation display in the normal symbol display device 42. 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 audio lamp control device 262 is connected to the output of the output port 528. Further, an output port 529 is connected to the image controller 526 via a bus line 531.

  The CPU 521 of the display control device 45 controls the display of the normal symbol display device 42 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 a memory for.

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. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit 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 process (NMI interrupt processing in FIG. 44).

  The power supply unit 541 normally outputs an output of 5 volts, which is the drive voltage of the control system, for a time sufficient for the execution of the power failure process even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main controller 261 and the payout controller 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 normal symbol display device 42 is set with three symbol rows of left, middle and right, and the symbols (ordinary symbols) are variably displayed for each symbol row. In the present embodiment, the normal symbols are each configured with numbers “0” to “9”, and the normal symbols are displayed in ascending or descending order of the numbers to form a series of symbol strings. The normal symbol is displayed in a variable manner from top to bottom with periodicity.

  In such a case, in the left symbol row, the normal symbols are displayed in descending order (in the order in which the attached numbers decrease), and in the middle symbol row and right symbol row, the normal symbols are also in ascending order (in the order in which the attached numbers increase). Is displayed. Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, the normal symbol is hit on the normal symbol display device 42 and a combination of symbols (in this embodiment, the same normal symbol sequence) If it is arranged in combination, it will be “win”.

  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 (winning lottery) of the normal symbol display device 42, setting of symbol display, and the like using various counter information in the game. Specifically, 29, the winning random number counter C1 used for the lottery of the normal symbol display device 42, the winning symbol counter C2 used for the selection of the winning symbol of the normal symbol display device 42, and the normal 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 hit random number counter C1, and variation type counter used for variation pattern selection of normal symbol display device 42 CS1, CS2, and left / middle / right out symbol counter CL used to set each out symbol in the left, middle and right columns CM, it has been with the use of the CR.

  Among these counters, 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. Further, the RAM 503 is provided with a holding ball storage area as a storage area composed of one execution area and four holding areas (holding first to holding fourth areas). Each value of the winning random number counter C1, the winning symbol counter C2, and the reach random number counter C3 is stored in time series in accordance with the winning history of the game balls to the symbol operating port 33.

  The respective counters will be described in detail. The hit random number counter C1 is incremented by 1 in the range of 0 to 676, for example, and reaches a maximum value (that is, 676) and then returns to 0. In particular, when the winning random number counter C1 makes one round, the value of the initial random number counter CINI at that time is read as the initial value of the winning random number counter C1. The random number initial value counter CINI is a loop counter similar to the winning random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and repeatedly within the remaining time of normal processing. The hit random number counter C1 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 normal symbol operating port 33. The number of random number values to be won is set to two types at low probability and high probability. In this embodiment, the number of random number values to be hit at low probability is 2, and the value is “337, 673”, and the number of random number values to be hit at the time of high probability is 10, and the value is “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability is a state in which the probability of winning is increased as a value added and the subsequent probability of winning is increased, so-called probable change. Normal time (low probability) is such a state. It is said that it is not in a certain state.

  The winning symbol counter C2 determines the symbol when the normal symbol display device 42 is stopped when winning, and in the present embodiment, the normal symbol display device 42 has 10 normal symbols set. 10 (0-9) counter values are prepared. That is, the winning symbol counter C2 is incremented by 1 in order within the range of 0 to 9, and after reaching the maximum value (that is, 9), it returns to 0. The winning 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 normal symbol operating port 33.

  In addition, the reach random number counter C3 is configured to increment one by one within a range of, for example, 0 to 238 and return 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. Reach lottery may be individually set according to the state of the lottery probability of the normal symbol display device 42, the number of starting reserved balls at the start of change, and the like. The reach random number counter C3 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 normal symbol operating port 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 normal 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 (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. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode 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 the normal symbol display device 42 determines the fluctuation pattern at the start of the fluctuation of the normal symbol.

  The left, middle, and right off symbol counters CL, CM, and CR are displayed when the normal symbol display device 42 loses the winning lottery, and the left column normal symbol, the middle column normal symbol, and the right column normal symbol stop symbol (off) Since each of the 10 normal symbols is displayed in each column, 10 (0 to 9) counter values are prepared for each column. 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 this embodiment, the value of each counter CL, CM, CR is updated at random by using the value of the built-in R register 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 within 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 of the RAM 503 front / rear reach symbol buffer, 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 time of starting the variation of the normal symbol, the buffer value of any one of the front / rear out of reach symbol buffer, the reach symbol buffer other than front / rear out of symbol and the complete out of 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 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.

  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. 42 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 261 every 2 msec, for example.

  In FIG. 42, first, in step 601 (hereinafter, the step is simply indicated by symbol S), reading processing of various winning switches is executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in S602, the switch detection information is stored. Various switches are provided on the back surface of the game board 30, and these switch detection information is stored in a corresponding buffer area of the RAM 503.

  In subsequent S603, the random number is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in the present embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. Further, the winning random number counter C1, the winning symbol counter C2, and the reach random number counter C3 are updated. Specifically, the winning random number counter C1, the winning symbol counter C2, and the reach random number counter C3 are each incremented by 1 and their counter values have reached the maximum values (in the present embodiment, 676, 49, 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.

  After that, in S604, a start winning process associated with winning the normal symbol operating port 33 is executed. This start winning process will be described with reference to the flowchart of FIG. 43. In S701, whether or not the game ball has won the normal symbol operating port 33 is determined based on the detection information of the normal symbol operating port switch 225. When it is determined that the game ball has won the normal symbol operating port 33, in subsequent S702, it is determined whether or not the number N of starting reserved balls of the normal symbol display device 42 is less than the upper limit value (4 in the present embodiment). Determine. The process proceeds to S703 on the condition that there is a winning in the normal symbol operation port 33 and the number N of starting reserved balls is smaller than 4, and the number N of starting reserved balls is incremented by one.

  In subsequent S704, a random number related to the winning of the normal symbol is acquired. Specifically, each value of the winning random number counter C1, the winning symbol counter C2, and the reach random number counter C3 updated in S603 is stored in the first area of the free storage area 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. 44 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. 44 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 processing of FIG. 44, first, in S801, the used registers are saved in the backup area 503a of the RAM 503, and in the subsequent S802, the value of the stack pointer is stored in the backup area 503a. In step S803, the information on the occurrence of power interruption is set in the backup area 503a. In step S804, a power interruption notification command indicating that the power has been interrupted is transmitted to another control apparatus.

  In 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 S806, RAM access is prohibited. Thereafter, an infinite loop is entered in preparation for the power supply being completely shut down and the processing being impossible.

  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. 44 starts the NMI interrupt processing shown in FIG. The contents are as described with reference to FIG. 44 (however, the transmission of the power-off notification command in S804 is excluded).

  FIG. 30 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 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 S102, a payout permission command is transmitted to the payout control device 311. In S103, RAM access is permitted.

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, in S104, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON), and in subsequent S105, whether or not power-off occurrence information is set in the backup area 503a of the RAM 503 is determined. Is determined. In S106, a RAM determination value is calculated. In subsequent 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, the pachinko machine 10 is turned on while pressing the RAM erase switch 323 when it is desired to return to the initial state when the power is turned on. Therefore, if the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (S114, etc.). Similarly, when the information on occurrence 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 (S114 or the like) of the RAM 503 in the same manner. That is, in S114, the used area of the RAM 503 is cleared to 0, and in the subsequent S115, initialization processing of the RAM 503 is executed. In 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 S108, the stack pointer before power-off is restored, and in S109, information on occurrence of power-off is cleared. In S110, a command for restoring the sub-side control device to the gaming state at the time of power-off is transmitted, and in S111, the used register is restored from the backup area 503a of the RAM 503. Further, in S112 and S113, after the interruption permission / non-permission is returned to the state before the power interruption, the process returns to the address before the power interruption.

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

  In FIG. 31, 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 normal symbol display device 42 displays the variation of the normal symbol. In addition, after the start of the change of the normal symbol, the change pattern command → the stop symbol command of the left symbol sequence → the stop symbol command of the right symbol sequence → the stop symbol command of the middle symbol sequence one by one in the order of normal processing (that is, 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 a stop symbol command, a variation pattern command, a confirmation command, etc. determines the display mode of the normal symbol display device 42 based on the various commands, and the display mode is determined as the normal symbol display device 42. Is displayed.

  Next, in 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 the subsequent S203, the outlier counters CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row are updated.

  The update process of each out symbol counter CL, CM, CR will be described in detail. As shown in FIG. 32, in S301, it is determined whether or not it is time to update the out symbol counter CL in the left symbol row. In S302, the medium symbol is determined. It is determined whether or not it is time to update the out-of-row symbol counter CM. If the update timing of the left symbol row (S301 is YES), the process proceeds to S303, and the left symbol row outlier symbol counter CL is updated. Further, if the update timing of the middle symbol row (YES in S302), the process proceeds to S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both S301 and S302 are NO), the process proceeds to S305 to update the off symbol counter CR of the right symbol sequence. In updating the outlier symbol counters CL, CM, and CR in S303 to S305, the lower 3 bits of the R register are added to the previous counter value, and 10 is subtracted when the addition result exceeds the maximum value. The calculation result is the current value of the outlier 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 S306, it is determined whether or not the combination of the updated out symbol counters CL, CM, and CR is a reach symbol combination. It is determined whether or not. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to S308, 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 a combination of reach other than front / back off, the process proceeds to S309, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. .

In the case of a combination other than the reach symbol, in S310, it is determined whether or not the combination of the deviating symbol counters CL, CM, CR is a combination of deviating symbols. Then, the combination of the off symbol counters CL, CM, and CR at that time is stored in the off symbol buffer of the RAM 503. If both S306 and S310 are NO, the symbols are aligned on the left, middle, and right, that is, it corresponds to a winning state. In such a case, the out symbol counters CL, CM, CR are stored in the buffer. This process is finished as it is.

  After the off symbol counter update process, in S204 of FIG. 31, the prize ball counting signal and the payout abnormality signal received from the payout control device 311 are read. After that, in S205, a normal symbol variation process for performing a normal symbol variation display by the normal symbol display device 42 is executed. By this normal symbol variation processing, a hit determination, a variation pattern of a normal symbol, etc. are set. However, details of the normal symbol variation process will be described later.

  Thereafter, in S206, an electric accessory process is executed. This process is a process for opening or closing the specific winning port 400 of the special device 32 when the “winning” state is reached. However, details of the electric accessory processing will be described later. In S207, special game processing is executed. This process is a process for generating a special gaming state generated by the operation of the large opening unit 462 based on the winning to the start winning unit 461. However, details of the special game process will be described later.

  Thereafter, in S208, it is determined whether or not the execution timing of the next normal process 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 execution timing of the next normal process (S209, S210). That is, in 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 the present 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 S210, update of the variation type counters CS1 and CS2 is executed (similar to 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 S201-S207 changes according to the state of the game, the remaining time until the next normal process execution timing is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. .

  Next, the normal symbol variation process of S205 in FIG. 31 will be described with reference to the flowcharts of FIGS.

  First, in S401, it is determined whether or not a winning is made to the normal symbol operating port 33. This processing is usually performed based on the detection result of the symbol operating port switch 225 (see FIG. 8). Here, when it is determined that the normal symbol operating port 33 has been won (S401: YES), the process proceeds to S402. On the other hand, if it is determined that the normal symbol operating port 33 has not been won (S401: NO), the process proceeds to S404.

  In S402, it is determined whether or not the number of the operation reservation balls of the normal symbol display device 42 is 4 or more. Here, when the number of holdings ≧ 4 (S402: YES), the process proceeds to S404. On the other hand, if the number of holds <4 (S403: NO), the process proceeds to S403.

  In S403, a random number is stored. This process stores various random values in the reserved ball storage area (see FIG. 29). Specifically, the winning random number counter C1, the winning symbol counter C2, and the reach random number counter C3 are stored.

  In S404, it is determined whether the electric accessory 402 of the special device 32 is operating. When the electric accessory 402 is in operation, a hit state has occurred. If it is determined that the electric accessory 402 is operating (S404: YES), the normal symbol variation process is terminated. On the other hand, when it is determined that the electric accessory 402 is not in operation (S404: NO), the process proceeds to S405.

  In S405, it is determined whether or not the number of operation suspensions of the normal symbol display device 42 is zero. If the number of holds is 0 (S405: YES), the normal symbol variation process is terminated. On the other hand, when the number of holdings is not 0 (S405: NO), the process proceeds to S406.

  In S406, it is determined whether or not the normal symbol is changing. When it is determined that the normal symbol is changing (S406: YES), the process proceeds to S407 in FIG. On the other hand, if it is determined that it is not changing (S406: NO), the process proceeds to S416 in FIG.

  In S407 of FIG. 34, which is shifted to when the normal symbol is not changing, it is determined whether or not the time for changing the display time is set. In the case of the probability variation mode, which will be described later, the variation display time reduction is set. If it is determined that there is a shortening (S407: YES), a shortening command is transmitted to the display control device 45 in S408, and the process proceeds to S409. On the other hand, when it is determined that there is no shortening (S407: NO), the process of S408 is not executed, and the process proceeds to S409.

  In S409, it is determined whether or not the variation time that is the variation display time has elapsed. If it is determined that the variation time has elapsed (S409: YES), a stop command is transmitted to the display control device 45 in S410, the display time is set in S411, and the process proceeds to S412. When the stop command is transmitted, the normal symbol display device 42 performs a fixed stop display of the normal symbol. In S411, the time for this fixed stop display is set. On the other hand, when it is determined that the variation time has not elapsed (S409: NO), the subsequent symbol variation processing is terminated without executing the subsequent processing.

  In S412, it is determined whether the display time of the fixed stop display has elapsed. If it is determined that the display time has elapsed (S412: YES), the process proceeds to S413. On the other hand, when it is determined that the display time has not elapsed (S412: NO), the subsequent process is not executed and the normal symbol variation process is terminated.

  In S413, it is determined whether or not it is a winning symbol. In this process, it is determined whether or not the normal symbols displayed in a fixed stop state are in a specific combination. If it is determined that the symbol is a winning symbol (S413: YES), the electric accessory 402 is operated in S414, and the normal symbol variation process is terminated. On the other hand, when it is determined that the symbol is not a winning symbol (S413: NO), the processing of S414 is not executed, and the normal symbol variation process is terminated.

  In S415 of FIG. 35, which is shifted when a negative determination is made in S406 in FIG. 33, it is determined whether or not it is during the display time. This display time is the display time of a regular symbol that has been confirmed and stopped, and is set in S411 in FIG. 34 as described above. If it is determined that the display time is being reached (S415: YES), the process proceeds to S412 in FIG. On the other hand, if it is determined that the display time is not being reached (S415: NO), that is, if a variable display is being made, the process proceeds to S416.

  In S416, it is determined whether or not there is a probability change state. In the present embodiment, when the predetermined symbols among the winning symbols are arranged, the probability changing state is subsequently performed. When a pattern that is not a specific symbol (non-specific symbol) is prepared, it does not shift to the probability variation state. If it is determined that the state is in the probability variation state (S416: YES), a hit determination in the probability variation state is performed in S417, and the process proceeds to S419. In the probability variation state, “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” among the numerical values 0 to 676 of the winning random number counter C1 is the winning value. On the other hand, if it is determined that the state is not the probability variation state (S416: NO), a hit determination in the non-probability variation state is performed in S418, and the process proceeds to S419. In the non-probable variation state, “337, 673” is a winning value among the numerical values 0 to 676 of the winning random number counter C1.

  In S419, a variation time that is a time for displaying a variation of a normal symbol is set. In step S420, a change start command is transmitted to the display control device 45. As a result, the normal symbol display device 42 starts the variable symbol normal display.

  Next, the electric accessory processing in S206 in FIG. 31 will be described with reference to the flowcharts in FIGS.

  First, in S501, it is determined whether or not the electric accessory 402 of the special device 32 is in operation. If it is determined that the electric accessory 402 is in operation (S501: YES), the process proceeds to S502. On the other hand, when it is determined that the electric accessory 402 is not in operation (S501: NO), the electric accessory process is terminated.

  In S502, it is determined whether or not the specific winning opening 400 is open. If it is determined that the specific winning opening 400 is open (S502: YES), the process proceeds to S503. On the other hand, when it is determined that the specific winning opening 400 is not open (S502: NO), the process proceeds to S506 in FIG.

  In S503, it is determined whether or not the opening time of the specific winning opening 400 has elapsed. In the present embodiment, the opening time of the specific winning opening 400 is 4.0 seconds or 5.8 seconds. If it is determined that the opening time has elapsed (S503: YES), the process proceeds to S505. On the other hand, when it is determined that the opening time has not elapsed (S503: NO), the process proceeds to S504.

  In S504, it is determined whether the required number of winnings has been won. The number of game balls won in the specific winning opening 400 is counted by the specific winning opening switch 403. Here, when it is determined that the required number of winnings has been won (S504: YES), the specific winning opening 400 is closed in S505, and the electric utility process is terminated. On the other hand, when it is determined that the required number of winnings has not been won (S504: NO), the process of S505 is not executed and the electric accessory process is terminated.

  In S506 of FIG. 37 that is shifted to when the negative determination is made in S502, it is determined whether or not the remaining ball processing time has elapsed. The remaining ball processing time is the time until the game ball that has won the specific winning opening 400 and is stopped at the stopping portion is discharged from the predetermined passage after being released from the stopping state. If it is determined that the remaining sphere processing time has elapsed (S506: YES), the process proceeds to S510 in FIG. On the other hand, when it is determined that the remaining sphere processing time has not elapsed (S506: NO), the process proceeds to S507.

  In S507, it is determined whether or not it is a stop ball release timing. If it is determined that it is the stop ball release timing (S507: YES), the stop ball is released in S508, the passing information of the special device operation area 407 is stored in S509, and the electric machine processing Exit. The stop ball is released by driving a stop motor 411 (see FIG. 8). Further, the passage of the special device operation area 407 is detected by a special device operation area switch 408.

  In S510 of FIG. 38, which is shifted when an affirmative determination is made in S506 of FIG. 37, the operation of the electric accessory is stopped. In this process, the winning opening solenoid 421 is turned off and the electric accessory 402 is closed.

  In subsequent S511, it is determined whether or not the special device 32 is in operation. Here, when it is determined that the special device 32 is in operation (S511: YES), the subsequent processing is not executed and the electric accessory processing is terminated. On the other hand, when it is determined that the special device 32 is not in operation (S511: NO), the process proceeds to S512.

  In S512, it is determined whether or not the game ball has passed through the special device operation area 407. This determination is made based on the passage information stored in S509 in FIG. Here, when it is determined that the game ball has passed through the special device operation area 407 (S512: YES), the electric accessory processing is terminated. On the other hand, if it is determined that it has not passed (S512: NO), the process proceeds to S513.

  In S513, it is determined whether or not the winning pattern is a specific symbol. Here, when it is determined that the winning is based on the specific symbol (S513: YES), the process shifts to the probability changing state in S515, and the electric utility process is terminated. On the other hand, when it is determined that the winning is not based on the specific symbol (S513: NO), the process proceeds to S514.

  In S514, it is determined whether or not the state is a probability variation state. Here, when it is determined that the state is a certain variation state (S514: YES), the certain variation state is canceled in S516, a transition to the normal state is performed, and the electric accessory processing is terminated. On the other hand, when it is determined that the state is not a certain change state (S514: NO), the process of S516 is not executed, and the electric accessory process is terminated.

  Next, the special game process of S207 in FIG. 31 will be described with reference to the flowcharts of FIGS.

  First, in S1301, it is determined whether or not the special device 32 is in operation. If it is determined that the special device 32 is in operation (S1301: YES), the process proceeds to S1302. On the other hand, if it is determined that it is not operating (S1301: NO), the process proceeds to S1307 in FIG.

  In S1302, it is determined whether or not the game ball has passed through the special device operation area 407. This determination is made based on the passage information stored in S509 in FIG. If it is determined that the game ball has passed through the special device operation area 407 (S1302: YES), the process proceeds to S1303. On the other hand, if it is determined that it has not passed (S1302: NO), the process proceeds to S1311 in FIG.

  In S1303, the operation of the special device 32 is stopped. In subsequent S1304, it is determined whether or not the large opening 471 of the large opening unit 462 is closed. Here, when it is determined that the large opening 471 is in the closed state (S1304: YES), the process proceeds to S1305. On the other hand, when it is determined that the large opening 471 is not closed (S1304: NO), the special game process is terminated.

  In S1305, it is determined whether or not the special device 32 is activated with a specific symbol. If the special device 32 is operated with a specific symbol (S1305: YES), the process proceeds to the probability change state in S1306, and the special game process is terminated. On the other hand, when it is not the operation of the special device 32 by the specific symbol (S1305: NO), the process of S1306 is not executed and this special game process is terminated.

  In S1307 of FIG. 40, which is shifted when a negative determination is made in S1301, it is determined whether or not the game ball has passed through the special device operation area 407. This determination is made based on the passage information stored in S509 in FIG. If it is determined that the game ball has passed through the special device operation area 407 (S1307: YES), the special device 32 is operated in S1308, and the process proceeds to S1309. On the other hand, if it is determined that it has not passed (S1307: NO), the process proceeds to S1315 in FIG.

  In S1309, it is determined whether or not there is a probability variation state. If it is determined that the state is in the probability variation state (S1309: YES), the probability variation state is canceled in S1310, and the process proceeds to S1311. On the other hand, when it is determined that the state is not in the certain change state (S1309: NO), the process of S1310 is not executed and the process proceeds to S1311.

  When a negative determination is made in S1302 of FIG. 39, a negative determination is made in S1309, or in S1311 that moves from S1310, it is determined whether or not a game ball has won a special start opening 465 of the start winning unit 461. To do. If it is determined that the game ball has won the special starting port 465 (S1311: YES), the large opening 471 of the large opening unit 462 is opened in S1312, and the process proceeds to S1313. On the other hand, if it is determined that no winning is made (S1311: NO), the process proceeds to S1315 in FIG.

  In S1313, it is determined whether or not a specified number of game balls have won the special start opening 465. If it is determined that a predetermined number of game balls have been won (S1313: YES), the operation of the special device 32 is stopped in S1314, and the process proceeds to S1315 in FIG. On the other hand, when it is determined that the prescribed number of game balls have not won (S1313: NO), the processing of S1314 is not executed, and the process proceeds to S1315 of FIG.

  When a negative determination is made in S1307, S1311, or S1313 in FIG. 40, or in S1315 that moves from S1314, it is determined whether or not the large opening 471 is in a closed state. If it is determined that the large opening 471 is in the closed state (S1315: YES), the special game process is terminated. On the other hand, if it is determined that it is not in the closed state (S1315: NO), that is, if it is in the open state, the process proceeds to S1316.

  In S1316, it is determined whether or not the opening time of the large opening 471 has elapsed. In this embodiment, the one opening time of the large opening 471 is 5 seconds. If it is determined that the opening time has elapsed (S1316: YES), the process proceeds to S1318 without executing the process in S1317. On the other hand, when it is determined that the opening time has not elapsed (S1316: NO), the process proceeds to S1317.

  In S1317, it is determined whether or not a prescribed number of game balls have won the large opening 471. Here, when it is determined that a prescribed number of game balls have won (S1317: YES), the process proceeds to S1318. On the other hand, if it is determined that no winning is made (S1317: NO), the special game process is terminated.

  In S1318, the large opening 471 is closed. In this process, the large opening solenoid 226 is deenergized, and the electric accessory 472 corresponding to the large opening 462 is closed. In subsequent S1319, it is determined whether or not the special device 32 is in operation. If it is determined that the special device 32 is in operation (S1319: YES), the special game process is terminated. On the other hand, when it is determined that the special device 32 is not in operation (S1319: NO), the process proceeds to S1320.

  In S1320, it is determined whether or not the operation of the special device 32 is based on a specific symbol. Here, when it is determined that the symbol is based on the specific symbol (S1320: YES), a transition to the probability change state is performed in S1321, and then the special game process is terminated. On the other hand, when it is determined that it is not based on the specific symbol (S1320: NO), the process of S1321 is not executed, and this special game process is terminated.

  The details of the normal symbol variation process, the electric accessory process, and the special game process have been described above. In the present embodiment, whether or not the winning symbol is determined in the normal symbol changing process (S413 in FIG. 34), depending on the winning symbol, the state where the special device 32 can be stopped, the opening time of the electric accessory 402, It is characterized by making different. The opening time of the electric winning combination means that after the electric winning combination 402 is operated in S414 in FIG. 34 and the specific winning opening 400 is opened, the specific winning opening 400 is closed in S505 in FIG. 36, and in S510 in FIG. Is the processing time ("opening processing") until the operation of the electric accessory 402 is stopped.

  Specifically, the normal symbols are configured to be given numbers “0” to “9”, respectively. However, when the numbers given to the normal symbols are “3” and “7” in the case of a big hit, A second stopping state in which the required number of stops is one is set, and the opening time is 5.8 seconds. In addition, if the number attached to the normal symbol is “1”, “5”, “9” in the case of a big win, the second stoppable state with one required stop is set and the opening time is 4 .0 seconds. Furthermore, in the case of “2”, “8”, “0”, the first stop state where the required number of stops is 3, and the release time is 5.8 seconds. In the case of “4” and “6”, the first stop possible state where the required number of stops is 3, and the release time is 4.0 seconds.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 45 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

  First, in 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 the main control device 261 is received. When the payout permission command is received, the process proceeds to S903 to permit the RAM access, and the external interrupt vector is set in S904.

  Thereafter, a data backup process is executed for the RAM 513 in the CPU 511. That is, in S905, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (ON), and in subsequent S906, whether or not power-off occurrence information is set in the backup area 513a of the RAM 513 is determined. Is determined. In step S907, a RAM determination value is calculated. In the subsequent step S908, it is determined whether 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 RAM initialization processing (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 (S915 or the like) of the RAM 513 in the same manner. That is, in S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent S916, initialization processing of the RAM 513 is executed. In S917, the CPU peripheral device is initialized, and in S918, the 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 S909, the stack pointer before the power interruption is restored, and in S910, the information on the occurrence of the power interruption is cleared. In S911, the CPU peripheral device is initialized, and in S912, the used register is restored from the backup area 513a of the RAM 513. Furthermore, in S913 and S914, after returning the interruption permission / non-permission to the state before the power interruption, the process returns to the address before the power interruption.

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

  In FIG. 46, in S1001, a command from the main controller 261 is acquired and the total number of prize balls is stored. In step S <b> 1002, the launch permission is set for the launch control device 312. In 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 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 S1005, setting of a tank ball absence state or a tank ball absence release state is executed according to a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and the special setting for the absence of the tank ball and the setting for the no tank ball state are executed. Perform configuration.

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

  In S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not payable and the total number of prize balls stored in S1001 is not 0 (both S1007 and S1008 are NO), the process proceeds to S1009 and a prize ball control process (FIG. 47 described later). To start. Further, if the prize ball cannot be paid out or if the total number of prize balls is 0 (YES in either S1007 or S1008), the process proceeds to a lending payout process.

  After that, in S1010 to S1012, a rental ball payout process is executed. In this case, if it is not possible to pay out the rented ball and if a rented ball payout request from the card unit has been received (NO in S1010, YES in S1011), the process proceeds to S1012 and the renting control process (FIG. 48 described later). ). Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in S1010 or NO in S1011), a subsequent ball removal process is executed.

  In S1013, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal is not disabled and the ball removal operation is not started. In subsequent S1014, control of vibrator 360 (vibration motor control) is executed on the 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. 47, in S1101, the payout motor 358a is driven to execute prize ball payout. In subsequent 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 S1103, the payout motor 358a is driven to execute a retry process, and the stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

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

  If the game ball count is normal, the process proceeds to S1106, where 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, a stop process of the payout motor 358a is executed in S1107, and then the process returns to the payout control process of FIG.

  In the ball lending control process shown in FIG. 48, in S1201, the payout motor 358a is driven to execute lending of a lending ball. In subsequent S1202, 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 S1203, the payout motor 358a is driven to execute a retry process, and the stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to S1204, 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 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.

  Further, if the game ball count is normal, the process proceeds to 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, the stop process of the payout motor 358a is executed in S1207, and then the process returns to the payout control process of FIG.

  In addition, the ball receiving portions 404a and 404b in the present embodiment correspond to “stop units”, and the special device 32 corresponds to “stop device”. In addition, the normal symbol display device 42 of the present embodiment corresponds to “identification information display device”, the specific winning opening 400 corresponds to “variable ball entry means”, and the special device operation area 407 corresponds to “specific ball entry means”. Equivalent to.

  As described in detail above, in the present embodiment, the necessary number of stops in the stop portion of the special device 32 can be changed. Specifically, the required number of stops can be three or one. Accordingly, it is necessary to stop three game balls under a certain situation, but it is possible to give a wide range of games so that it is sufficient to stop only one game ball under another situation. As a result, the interest of the game can be improved.

  As a change method, a first stoppable state and a second stoppable state are prepared as the stoppable states of the ball receiving portions 404a and 404b. In the 1st stoppage possible state, it arrange | positions so that the opening part may face inward upper direction. Accordingly, the first game ball that has entered the specific winning opening 400 is stopped at one of the ball receiving portions 404a or 404b. Next, the second game ball is stopped at the other ball receiving portion 404b or 404a. Then, the third game ball is stopped so as to be stacked in the middle of the two game balls stopped at the ball receiving portions 404a and 404b. In this case, the required number of stops is three. On the other hand, in the 2nd stop possible state, it arrange | positions so that the opening part may face right above. In this case, the first game ball that has entered the specific winning opening 400 is supported by the inner ends of the ball receiving portions 404a and 404b and is stopped at the central portion. In this case, the required number of stops is one. In this way, the required number of stops can be changed easily.

  Further, in the present embodiment, such setting of the required number of stops, that is, the transition to the first or second stoppable state is performed when the normal symbol variation process determines that it is a winning symbol (S413 in FIG. 34). ), Depending on the type of winning symbol. Therefore, the possibility that the game played after the determination of the winning symbol (after the specific condition is established) becomes monotonous is reduced. As a result, the game can be widened and the interest of the game can be improved.

  Furthermore, in this embodiment, the opening time of the electric accessory 402 can be changed. The opening time of the electric winning combination means that after the electric winning combination 402 is operated in S414 in FIG. 34 and the specific winning opening 400 is opened, the specific winning opening 400 is closed in S505 in FIG. 36, and in S510 in FIG. Is the processing time ("opening processing") until the operation of the electric accessory 402 is stopped. Thereby, coupled with the fact that the required number of stops can be changed, the game can be further widened, and the fun of the game can be improved.

  Such setting of the opening time is also made according to the type of winning symbol when it is determined that it is a winning symbol in the normal symbol changing process (S413 in FIG. 34). Therefore, the possibility that the game played after the determination of the winning symbol (after the specific condition is established) becomes monotonous is reduced. As a result, the game can be widened and the interest of the game can be improved.

  In addition, it is not limited to the description content of the said embodiment, A various embodiment can be employ | adopted unless it deviates from the meaning of this invention.

  (A) For example, in the above-described embodiment, when the number assigned to the normal symbol in the case of winning is “3”, “7”, the second stoppable state where the required number of stops is one, The opening time was 5.8 seconds. In addition, if the number attached to the normal symbol is “1”, “5”, “9” in the case of a big win, the second stoppable state with one required stop is set and the opening time is 4 0 seconds. Furthermore, in the case of “2”, “8”, “0”, the first stop state in which the required number of stops is 3, and the release time is 5.8 seconds. In the case of “4” and “6”, the first stop possible state where the required number of stops is 3, and the release time was 4.0 seconds.

  On the other hand, such a correspondence relationship may be set from the outside. In this case, a symbol with a number that is advantageous to the player can be set on the hall side as a so-called lucky number symbol, so that the range of the game can be widened and the interest of the game can be improved.

  (B) Further, for example, in the above-described embodiment, the required number of stops and the opening time are selectively set by the numbers attached to the normal symbols. On the other hand, the required number of stops and the opening time may be set according to the lottery result when winning is determined.

  Further, the required number of stops may be set according to the type of normal symbol, and the opening time may be set based on the lottery result. Of course, on the contrary, the opening time may be set according to the normal symbol type, and the required number of stops may be set based on the lottery result.

  Further, the pachinko machine 10 may have a plurality of modes as an internal state, and in addition to or instead of the normal symbol type, the required number of stops and the opening time may be set in accordance with the transition of this mode. For example, it may be possible to prepare a heaven mode with a small required number of stops and a long open time, a hell mode with a large number of required stops and a short open time, and the like.

  (C) In the above embodiment, the required number of stops and the opening time are changed during the game, but it is also possible to adopt a configuration that can be fixedly set from the outside. For example, in setting 1, the second stoppable state where the required number of stops is one and the release time is 5.8 seconds. Further, in setting 2, the second stoppable state where the required number of stops is one and the release time is 4.0 seconds. Furthermore, in setting 3, the first stop state in which the required number of stops is three and the release time is 5.8 seconds. Also, in setting 4, the first stop possible state where the required number of stops is 3, and the release time is 4.0 seconds. In this way, even if it is the same model, the game can be widened by the setting. Therefore, for example, different game characteristics can be derived for each hole.

  (D) In the above embodiment, both the required number of stops and the opening time can be changed. However, if at least the required number of stops can be changed, the range of games can be expanded and the interest of the game is improved. be able to.
