There is a case. This game ball is guided to the front side of the front and rear ball passage 631 through the upper ball passage 601. The game ball is guided to the upper side of the side ball passage 551 through the front and rear ball passages 631 descending from the front to the rear. The game ball guided to the upper side of the side ball passage 551 falls on the side ball passage 551, reaches the left and right side portions of the upper surface of the lower frame portion 610, and is led out to the stage surface FS. As described above, a convex portion is formed on the back portion of the leg portion 574a on the non-projecting side, and a concave portion 573b is formed on the LED cover 573, so that the side ball passage 551 is played. When the ball falls, the game ball comes into contact with the convex portion and the concave portion 573b so that the falling speed is reduced. As a result, the game ball dropped in the side ball passage 551 is smoothly led out to the stage surface FS. The game ball derived to the stage surface FS is derived to the game board 30 as a result of rolling as shown in FIG. In FIG. 10, the state of rolling of the game ball led out from the right side ball passage 551 to the stage surface FS is shown, but the same applies to the right side ball passage 551. Further, the rolling of the game ball is not limited to the rolling shown in FIG. 10, but naturally there are other rolling modes. However, even though there are various processes until the game ball is led out to the game board 30, the lead-out location when the game ball is led out to the game board 30 is similar to the three modes of FIG.

  In FIG. 10A, as shown by the dotted line, the game ball that has reached the left side portion of the upper surface of the lower frame portion 610 from the left side ball passage 551 is led out to the stage surface FS. Then, the game ball derived to the stage surface FS moves to the right along the stage surface FS and reaches the vicinity of the right end portion of the upper surface. The game ball that has reached the vicinity of the right end is reversed and moves to the left toward the center. Then, the game ball that has reached the rear side of the mountain portion 594a in a state where the speed in the left-right direction is substantially zero is guided to the descending ball path 593 through the rear guide path 596. The game ball guided to the ball passage 593 falls downward along the ball passage 593 and is guided to the recess 614. The game ball guided to the recess 614 is guided to the opening 613a along the guide path 614a, and is led out to the game board 30 from the opening 613a.

  In FIG. 10B, as in the case of FIG. 10A, the game ball that has reached the left side portion of the upper surface of the lower frame portion 610 from the left side ball passage 551 as shown by the dotted line is the stage surface FS. , To the right side of the upper surface, and in the vicinity of the right end of the upper surface, and reaches the front side of the peak portion 594a with the speed in the left-right direction becoming substantially zero. The game ball that has reached the front side of the mountain portion 594a descends the front guide path 595, and is led out from the notch 613b of the front base frame 600 to the game board 30.

  In FIG. 10C, as in the case of FIGS. 10A and 10B, the game ball that has reached the left side portion of the upper surface of the lower frame portion 610 from the left side ball passage 551 as shown by the dotted line is shown in FIG. Then, it moves to the right along the stage surface FS, reverses near the right end of the upper surface, and reaches the center. The game ball that has reached the central portion further moves to the left after passing the mountain portion 594a and moves to the valley portion 594b on the left side. As described above, since the valley portion 594b is inclined downward toward the front, the game ball that has reached the left valley portion 594b rolls to the left and right around the valley portion 594b. While being guided forward. Then, the game ball that has reached the drop portion 613c of the front base frame 600 is led out to the game board 30 from the drop portion 613c. In this case, the mode is derived from the left drop unit 613c to the game board 30, but there may be a mode derived from the right drop unit 613c to the game board 30.

  Among the above three modes, in the case of (a) and (b), the opening 613a and the notch 613b are positioned vertically above the operation port 33, so that the ball entering the operation port 33 is compared to the case of (c). Is likely to occur.

  The center frame 43 is provided with a pair of left and right door bodies 171 and 172 that form a substantially rectangular plate shape so as to overlap a part of the display screen of the first symbol display device 41. The door bodies 171 and 172 and members for operating the door bodies 171 and 172 will be described below with reference to FIGS. 6, 9, 11, and 12. In the following description, the right door 171 is referred to as “right door 171” and the left door 172 is referred to as “left door 172” as appropriate for convenience of description.

  As shown in FIG. 9A, the right door 171 and the left door 172 both have a substantially rectangular plate shape having the same size, and are displayed at the upper right corner on the display screen G of the first symbol display device 41. A right door 171 is provided, and a left door 172 is provided at the upper left corner. The center frame 43 has at least the upper side of the display screen G projecting forward from the game board 30 to the front of the pachinko machine, and the right door 171 and the left door 172 are arranged directly below the projecting portion (projected portion). The right door 171 and the left door 172 are spaced apart from each other by a space having substantially the same size as the doors 171 and 172. When the display screen G of the first symbol display device 41 is divided into 9 parts by dividing the display screen G vertically and horizontally, the right door 171 and the left door 172 generally have a size corresponding to one of the 9 parts. That is, at this time, the right door 171 and the left door 172 are disposed so as to overlap the display screen G of the first symbol display device 41, so that an area of about 1/9 × 2 of the display screen G is hidden. It is like that.

  The procedure for assembling the doors 171 and 172 to the center frame 43 will be described with reference to FIG.

  Solenoids 177 and 184 for operating the door bodies 171 and 172 are assembled to the left and right rear surfaces of the upper frame portion 630 of the front base frame 600, respectively. The solenoids 177 and 184 include output shafts 178 and 185 and springs 179 and 186, respectively. On the output shafts 178 and 185 of the solenoids 177 and 184, movable connecting portions 174 and 180 having two links 175, 176, 182 and 183, respectively, straddle the opening 580 a of the rear base frame 550. Assembled. This assembly is performed by connecting the first links 176 and 183 to the output shafts 178 and 185, respectively. The second links 175 and 182 of the movable connecting portions 174 and 180 are assembled to the arm portions 171b and 172b of the door bodies 171 and 172 by screws 187 on the back side of the rear base frame 550, respectively. The door bodies 171 and 172 are rotatably supported by the rear base frame 550 by supporting shafts 173 and 181 at shaft portions 171a and 172a provided at the base end portions. In addition, in order to prevent the door bodies 171 and 172 from being detached rearward, the fixing members 189 and 190 are assembled so as to cover the shaft portions 171a and 172a of the door bodies 171 and 172. The fixing members 189 and 190 are assembled in such a manner that the screws 192 and 193 are inserted into the screw insertion holes 189a and 190a provided in the fixing members 189 and 190 from the back side, and the screws 192 and 193 are moved back in this state. This is performed by screwing into a screw screw portion (not shown) provided in the base frame 550. Thereby, the door bodies 171 and 172 are disposed at the upper right corner and the upper left corner of the frame-like portion that penetrates the center frame 43 in the front-rear direction. That is, the door bodies 171 and 172 are positioned directly below the upper frame portion 580 of the rear base frame 550 and the upper frame portion 630 of the front base frame 600. Further, the shaft portions 171a and 172a, the arm portions 171b and 172b, the movable connecting portions 174 and 180 of the door bodies 171 and 172 are provided on the outside along the side wall portion 570 and the upper frame portion 580, and as a result. These are arranged so as to surround the display screen G of the first symbol display device 41. At this time, the output shafts 178 and 185 of the solenoids 177 and 184 are extended by the inelastic force of the springs 179 and 186, and in this state, the door bodies 171 and 172 face the display screen G, that is, the display screen G It is kept in a state of hiding a part.

  Next, the drive mechanism of the right door 171 and the left door 172 will be described with reference to FIGS. FIG. 11 is a view for explaining the configuration of the drive mechanism of the door bodies 171 and 172. FIG. 11 basically shows a cross section taken along line AA of FIG. 9B, but for convenience of explanation, it is shown with the peripheral wall 191 surrounding the display screen G of the first symbol display device 41 removed. Yes. The right door 171 is shown in a closed state, and the left door 172 is shown in an open state. In FIG. 11, the first symbol display device 41 is attached to the frame cover 213 behind the game board 30, and a display control device 214 described later is installed behind the first symbol display device 41.

  In the right door 171 and the left door 172 having the above-described configuration, for example, when the solenoid 184 on the left door 172 side is energized, the output shaft 185 contracts against the urging force of the spring 186, as shown in FIG. Accordingly, the links 182 and 183 are swung. Then, the left door 172 rotates about the shaft portion 172a, so that the left door 172 shifts to an upright state with respect to the display screen G (open state in the figure). Of course, the same applies to the operation of the right door 171. In addition, the 1st symbol display apparatus 41 is provided in the position somewhat behind the surface of the game board 30, and it is between the display screen G of the 1st symbol display apparatus 41, and the glass 137 of the front surface of the pachinko machine 10. A sufficient interval is secured. Therefore, when the doors 171 and 172 are operated, the forward movement can be performed without any trouble.

  As shown in FIG. 9B, a relay board 188 is provided between the drive mechanisms of the right door 171 and the left door 172. A drive signal is output to the solenoids 177 and 184 of the doors 171 and 172 via the relay substrate 188, and the solenoids 177 and 184 are energized according to the drive signal. At this time, the right door 171 and the left door 172 are independently opened and closed.

  When the right door 171 and the left door 172 shift from the closed state to the open state, the display form (size and shape of the image display area) is changed on the display screen G of the first symbol display device 41. In FIG. 12, the example of a display form in the display screen G of the 1st symbol display apparatus 41 is shown.

  12A shows a display form when both the right door 171 and the left door 172 are in the closed state. In this state, the upper right corner and the upper left corner of the display screen G of the first symbol display device 41 are hidden by the right door 171 and the left door 172, and are sandwiched between the right door 171 and the left door 172 in the upper area of the display screen G. Only the center part is exposed. At this time, about 2/9 of the entire screen area of the first symbol display device 41 is hidden by the right door 171 and the left door 172.

  (B) has shown the display form in the state which the right door 171 opened and the left door 172 closed. In this state, the upper left corner of the display screen G of the first symbol display device 41 is hidden by the left door 172, and the right 2/3 portion is exposed in the upper area of the display screen G. Further, (c) shows a display form in a state where the right door 171 is closed and the left door 172 is opened. In this state, the upper right corner of the display screen G of the first symbol display device 41 is hidden by the right door 171, and the left 2/3 portion is exposed in the upper area of the display screen G. In the states (b) and (c), about 1/9 of the entire screen area of the first symbol display device 41 is hidden by either the right door 171 or the left door 172.

  Further, (d) illustrates a display form in a state where both the right door 171 and the left door 172 are opened. In this state, since the display screen G of the first symbol display device 41 is not hidden, the image display area is maximized, and display using the entire screen area is possible.

  As described above, the display form of the display screen G of the first symbol display device 41 is changed according to the open / closed state of the right door 171 and the left door 172, but the vertical direction of the display screen G in any display form. The longest display area in the horizontal direction is left. If it demonstrates in FIG. 12, as shown to (a), the center part pinched | interposed into the right door 171 and the left door 172 will remain as a display area, without being hidden. In this case, even if the right door 171 and the left door 172 are provided so as to overlap the display screen G, the impression that the display screen G is reduced is relatively small. Therefore, a suitable display effect can be achieved while effectively using the display screen G of the first symbol display device 41.

  Returning to the description of FIG. 4, the variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and a predetermined game ball is likely to win in a special game state (hereinafter referred to as a jackpot). It can be switched to the open state. More specifically, when a game ball wins in the operating port 33, the first symbol display device 41 displays the first symbol in a variable manner, and when the confirmed symbol after the stop is a combination of specific symbols set in advance, a big hit is given. Occur. The variable winning device 32 is configured to be in a predetermined open state so that the game ball can easily win. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, it is assumed that the condition for transition to a round is satisfied, and the variable prize-winning device 32 is repeatedly opened up to a maximum of a plurality of rounds (for example, 15 rounds).

  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 ball launching handle 18 is rotated. Thus, the game balls launched are guided to a predetermined game area through the rail unit 50. The rail unit 50 is composed of a ring-shaped resin molded product, and more specifically, a fluorine-containing polycarbonate resin is used to reduce frictional resistance. The rail unit 50 includes an inner rail portion 51 and an outer rail portion 52 that are provided in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion, and the outer rail portion 52 surrounds the upper open area of the inner rail portion 51 and is parallel to the left side portion of the inner rail 51. Are formed in a substantially semi-annular shape.

  The inner rail portion 51 is integrally formed with other resin portions, and is provided to stand substantially vertically on the surface of the game board 30. Further, the outer rail portion 52 has a support portion 52a that is integrally molded with other resin portions in the same manner as the inner rail portion 51, and is provided substantially upright on the surface of the game board 30. A sliding plate 52b is attached to the inner surface of 52a to make the flight of the game ball smoother. The sliding plate 52b is made of a long metal strip made of stainless steel, and is supported by the support portion 52a at a plurality of locations. In such a case, a guide rail is constituted by the inner rail portion 51 and the outer rail portion 52, and a ball guide passage is formed by a portion where these rail portions 51 and 52 face each other with a predetermined interval. In addition, in the site | part which the inner and outer rail parts 51 and 52 oppose, each rail part 51 and 52 is connected by the contact part 53 with the game board 30, and a ball | bowl guide path is formed in the groove shape open | released to the near side. Has been.

  In the rail unit 50, a return ball prevention member 54 is attached to a portion (left upper portion in FIG. 4) from which the game ball jumps out of the ball guide passage, and a portion corresponding to the maximum flight portion of the jumped game ball (FIG. 4). In the upper right part), a return rubber 55 is attached. The return ball preventing member 54 prevents a situation in which a game ball that has once jumped from the ball guide path to the upper part of the game board 30 returns to the ball guide path. In addition, the game ball launched at a predetermined momentum or more hits the return rubber 55 and is rebounded toward the center of the game area.

  An arc-shaped flange 56 projecting outward is formed on the outer periphery 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, screws or the like are inserted into the plurality of through holes formed in the flange 56 and the game board 30. The rail unit 50 is fastened to 30. Here, the upper and lower and left and right ends of the rail unit 50 are formed in a substantially linear shape. That is, the flanges 56 are cut off at the upper and lower and left and right ends of the rail unit 50 so that 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. It has become. The rail unit 50 is disposed such that the position of the gaming area on the gaming board 30 that is the maximum width reaches the left and right end positions of the gaming board 30. Note that, among the parts corresponding to the ball guide passages of the rail unit 50, in particular, with respect to the game ball receiving part, the corresponding flange 56 is provided from others in order to firmly attach the rail unit 50 and stabilize the flight of the game ball. There are also many screws (three in this embodiment, two in the other).

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail portion 52 so as to close a part of the ball guide passage. The convex portion 57 is formed so as to extend downward from the outer peripheral portion of the inner rail portion 51, and has a function of guiding a foul ball that does not reach the game area and flows backward in the ball guide passage to the foul ball passage 76 (see FIG. 3). Have The lower right corner and the lower left corner of the game board 30 are spaces (Sa, Sb in the figure) for sticking seals and plates such as certificate stamps, and in order to secure this attachment space, the flange 56 Notches 58a and 58b are formed in the upper and lower portions. By adopting a configuration in which a sticker such as a stamp is directly pasted on the game board 30, it is difficult to improperly paste the stamp or the like.

  In the game board 30, a relay terminal hole 59 penetrating in the front-rear direction is provided in the upper left part outside the rail unit 50, and through this relay terminal hole 59, a connector for connecting a relay terminal plate installed on the back of the game board 60 is exposed to the front side of the pachinko machine 10.

  Next, the game area will be described. The board surface of the game board 30 is divided into inner and outer areas by a rail unit 50 (inner and outer rail portions 51 and 52), and an inner area divided into a substantially circular shape is a game area. In particular, in the present embodiment, the game area divided on the board surface of the game board 30 is configured to be much larger than before. In the present embodiment, the distance from the uppermost point of the outer rail portion 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the extreme left position of the inner rail portion 51 from the extreme left position of the outer rail portion 52. The distance between them is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail portion 51 to the extreme right position of the inner rail portion 51 is 418 mm.

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. It demonstrates as an area | region remove | excluding. That is, since the game area does not include the ball guide path portion, the left limit position toward the game area is specified by the inner rail portion 51, not by the outer rail portion 52. Further, the right limit position toward the game area is specified by the inner rail portion 51, the lower limit position of the game area is specified by the lower end position of the game board 30 in which the out port 36 is formed, and the upper limit position of the game area. Is specified by the outer rail portion 52. Therefore, in the present embodiment, the width of the gaming area (maximum width in the left-right direction) is 418 mm, and the height of the gaming 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 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. That is, the width dimension of the game area is preferably as large as possible from the viewpoint of game area expansion. 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 or 480 mm or more. In other words, the height of the game area is preferably as large as possible from the viewpoint of game area expansion. In addition, about the combination of the said width | variety and height, it can be set as what combined the said numerical value arbitrarily. If the width or height of the game area exceeds a certain value, a part of the game area may exceed the board surface of the game board 30, but other members may be placed along the game board surface in the area beyond the game area. What is necessary is just to supplement by providing.

  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 a much larger area ratio than before. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the related art, so that the game board 30 having the same size as the conventional one is used as in the present embodiment. So, it can be said that the game area is considerably expanded. 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. In order to secure 80% or more, it is difficult to make the shape of the game area into a substantially circular shape. Therefore, it is preferable to have a shape in which the corner (for example, the lower right corner or the upper right corner) is expanded. .

  Moreover, 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 on 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.

  In relation to the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning the game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided at the center of the game area, the through-gate 34, the windmill 37, and a plurality of nails are provided on the left and right sides of the variable display unit 35. (Guide nails such as a triangular nail for guiding the game ball to the center) and other objects can be provided with a margin, and the flow of game balls in the game areas on the left and right sides of the variable display unit 35 It is not monotonous, and you can fully enjoy the behavior of the game ball.

  Notches 38 are formed on both the left and right sides of the game board 30 to avoid interference with the protruding areas from the left and right sides of the main body frame 12, and the maximum width of the game area on the game board 30 in the rail unit 50 It has already been described that the position reaches the left and right end positions of the game board 30, but as will be described later, reinforcing members (bearing brackets 235: FIG. 17) provided on the left and right sides of the main body frame 12. The game board 30 is attached to the main body frame 12 so as to have a width that leaves an area for arranging the locking device (base frame 247, interlocking rod 248, etc .: see FIG. 17). For these reasons, the game area is being expanded.

  Returning to the description of FIG. 3, in the resin base 25, below the window hole 26 (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 25 via a 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 game ball launch handle 18 is first launched obliquely upward along the launch rail 61 and then guided to the game area through the ball guide path. As described above, since the curvature of the ball guide passage is reduced by greatly expanding the game area as compared with the conventional game area, a device for stabilizing the launch ball is required. Therefore, in the present embodiment, the launch position of the game ball is lowered so that the inclination angle (launch angle) of the launch rail 61 is somewhat larger than the existing one (that is, the launch rail 61 is raised), and By forming the launch rail 61 so as to extend from the launch position of the game ball launcher to a position beyond the center position (out port 36) of the game area, the launch rail 61 is made longer than the existing one and sufficiently long. The ball guide distance is secured. Thereby, the game ball launched from the game ball launching device can be guided to the ball guide passage in a more stable state. Further, in order to stabilize the launch ball, the metal plate 62 provided with the launch rail 61 is enlarged, and the metal plate 62 is screwed at a number of locations (15 to 20 in this embodiment). Thus, the launch rail 61 is firmly positioned with respect to the game board 30.

  There is a predetermined gap between the firing rail 61 and the ball guide passage, and a foul ball passage 76 is provided below the gap. Therefore, if the game ball launched from the game ball launching device does not reach the return ball prevention member 54 and returns as a foul ball in the ball guide passage, the foul ball passes through the foul ball passage 76 to the lower plate 16. To be discharged. Incidentally, in the case of the present embodiment, the length of the launch rail 61 is about 240 mm, and the length of the gap (the length on the extension line of the launch rail 61) leading to the foul ball passage 76 at the tip of the launch rail is about 40 mm. .

  When the foul balls flow backward in the ball guide passage, most of them flow along the outer rail portion 52 and fall downward when reaching the lower end portion of the outer rail portion 52. Some rampage in the ball guide passage and jump to the inner rail 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 76. Thereby, all of the foul balls are reliably guided to the foul ball passage 76, 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 door frame 13 side (ball outlet leading from the most downstream portion of the upper plate 23). At this time, since the launch position of the game ball is lowered in this embodiment, the drop from the exit of the ball on the front door frame 13 side to the launch position becomes large, Guide members 63 and 64 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front door frame 13 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device is provided with a ball striking rod that is supported so as to be rotatable about the base end portion, and a game ball is launched along with the rotation of the ball striking ball. It is rare. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to a light metal such as aluminum and reducing the size of the hitting shaft, the head portion of the hitting ball (opposite to the base end) is required to ensure sufficient firing force. A weight is provided at the tip of the side. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, the hitting ball can be easily picked or caught, and the effect of facilitating adjustment of the hitting strength of the hitting tip can be obtained.

  In addition, a pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 18) provided on the back surface of the main body frame 12, and game balls are basically discharged from the first discharge port 66. When the passage leading to the upper plate 23 including the first outlet 66 is filled with game balls, the game balls are discharged from the second outlet 67 instead of the first outlet 66.

  The game ball guide unit 70 is configured to be visible with a transparent resin material such as polycarbonate resin, and between the main body frame 12 and the front door frame 13 with the front door frame 13 closed with respect to the main body frame 12. It is formed so that the thickness is comparatively thin so that it can be accommodated. The game ball guide unit 70 is integrally formed with the foul ball passage 76 described above. The game ball guide unit 70 is formed with a ball discharge passage 71 for communicating the discharge ports 66 and 67 with the lower plate 16. In the game ball guide unit 70, a communication port 72 communicating with the upper plate 23 is formed on the front side of the first discharge port 66 of the main body frame 12, and an opening / closing plate 73 is attached so as to close the communication port 72. ing. The opening / closing plate 73 is rotatably supported by a support shaft 74 and is always urged to a position where the communication port 72 is closed by a spring 75 as urging means.

  According to the above configuration of the game ball guide unit 70, the open / close plate 73 rises as shown in the figure by the urging force of the spring 75 when the front door frame 13 is opened, and the communication port 72 is closed. In this state, the game ball discharged from the first discharge port 66 is guided to the lower plate 16 through the ball discharge passage 71. Therefore, when the front door frame 13 is opened in a state where game balls are stored upstream of the communication port 72, the stored balls flow down to the lower plate 16 through the ball discharge passage 71 without spilling from the communication port 72. To do. That is, even in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 23 is directly provided on the front door frame 13, the game on the upstream side of the communication port 72 when the front door frame 13 is opened. The inconvenience of spilling a ball can be prevented. On the other hand, in the state where the front door frame 13 is closed, the opening / closing plate 73 is pushed open against the biasing force of the spring 75 by the ball passage rod 138 (see FIG. 2) provided on the back surface of the front door frame 13. . In this state, the game ball discharged from the first discharge port 66 is guided to the upper plate 23 through the communication port 72. Accordingly, the game ball upstream of the communication port 72 is paid out to the upper plate 23. A lower plate full tank switch for detecting that the game ball discharged to the lower plate 16 is full (full tank) is attached to the downstream side of the ball discharge passage 71 of the game ball guide unit 70.

  The resin base 25 is provided with a substantially rectangular small window 78 at the lower right portion of the window hole 26. Accordingly, the stamp or the like attached to the lower right corner space (Sa in FIG. 4) of the game board 30 can be viewed through the small window 78. It is also possible to directly paste a stamp or the like on the game board 30 from the small window 78.

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. This small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, and through the relay terminal hole 59 and the small window 79, the relay installed on the back of the game board. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is closed with respect to the main body frame 12, the pin is pushed in and the front door frame 13 is closed. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 13) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 12 side for grounding. Therefore, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

  A pair of upper and lower support brackets 81 and 82 are attached to the left end side (opening / closing axis line side) of the main body frame 12 as a support mechanism for supporting the front door frame 13 so that it can be opened and closed. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side, and the lower support fitting 82 is provided with a protruding shaft 84 protruding upward. The specific configuration of the front door frame 13 supported by the support fittings 81 and 82 will be described later. Further, a pair of upper and lower metal fittings 155 and 156 (see FIG. 2) provided on the open end side on the back side of the front door frame 13 is inserted into the right end side (the side opposite to the opening / closing axis) of the main body frame 12. Insertion holes 87 and 88 are provided, respectively. The pachinko machine 10 is configured such that a locking device for locking the main body frame 12 and the front door frame 13 is hidden behind the main body frame 12. Therefore, the front door frame 13 is locked to the main body frame 12 so that it cannot be opened by locking the metal fittings 155 and 156 to the locking device via the insertion holes 87 and 88.

  A cylinder lock 91 as a key member for locking and unlocking the main frame 12 with respect to the outer frame 11 and locking and unlocking the front door frame 13 with respect to the main frame 12 is installed at the lower right corner of the main frame 12. Has been. The cylinder lock 91 is integrated with the locking device, and only the cylinder lock 91 of the locking device is provided in a state of protruding in front of the main body frame 12. In this case, the cylinder lock 91 is provided at a position different from the position that is the maximum width of the game area. The cylinder lock 91 has a function to cover both the locking and unlocking of the main body frame 12 and the locking and unlocking of the front door frame 13, and when the key inserted into the key hole is turned counterclockwise (counterclockwise direction) When the key is unlocked and the key is turned to the right (clockwise direction), the front door frame 13 is unlocked.

  As shown in FIG. 2, a vertically long cover member 92 is attached to the main body frame 12 so as to surround the cylinder lock 91. Although detailed illustration is omitted, the cover member 92 has locking portions (hooks) formed at the upper end portion and the lower end portion thereof. Therefore, the cover member 92 is attached to the main body frame 12 by locking the upper locking portion to the main body frame 12 side and sandwiching the lower locking portion between the main body frame 12 and the front plate 14. . The front door frame 13 is formed with a notch 145 corresponding to the shape of the cover member 92. When the front door frame 13 is closed, the cover member 92 together with the front door frame 13 constitutes the front portion of the pachinko machine. . When the front door frame 13 is closed, the flange formed on the cover member 92 is pressed by the front door frame 13 to prevent the cover member 92 from rattling.

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 13 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape that is nearly circular, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape. Above the window part 101 of the front door frame 13, the frame width of the narrowest part is about 61 mm. The frame width dimension in the present embodiment is substantially the same as the distance between the uppermost part of the outer rail portion 52 (the upper end of the game area) and the upper end of the main body frame 12 in the main body frame 12, and is 85 mm to This is significantly shorter than the conventional model having the frame width of about 95 mm. Thereby, the visibility of the upper area in the game area can be easily ensured, and the large variable display unit 35 can also be arranged relatively upward. The dimension of the frame width (narrowest part) above the window portion 101 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 secured, the thickness may be 50 mm or less.

  The left and right frame portions of the front door frame 13 are restricted in reducing the frame width, and need a width dimension sufficient to ensure the strength of the front door frame 13 itself and the glass support strength. In the present embodiment, the narrowest part of the left and right frame parts has a frame width of about 44 mm. In this case, since the game area is greatly expanded in the pachinko machine 10, the frame width of the front door frame 13 is about 44 mm as described above on the left side when viewed from the front of the pachinko machine 10, that is, on the opening / closing axis side. On the other hand, the distance between the left end position of the outer rail portion 52 of the rail unit 50 and the left end position of the main body frame 12 is about 21 mm, and the latter dimension is considerably small. That is, in this configuration, in a state where the front door frame 13 is closed, a part of the ball guide passage overlaps and is covered with the left frame portion of the front door frame 13. However, even if it becomes difficult to visually recognize the game ball in the ball guide passage, the ball guide passage is only a passing area until the game ball is guided to the game area, and the game where the player mainly enjoys the game. The game ball is not difficult to view in the area. Therefore, there is no trouble in actual game. As described above, it is possible to expand the game area without causing any trouble to the game, while ensuring sufficient strength and glass support strength of the front door frame 13.

  Small windows 107 to which a transparent resin is attached are provided on both the left and right sides of the lower end portion of the front door frame 13 so that a part of the surface of the main body frame 12 and the surface of the game board 30 (including certificate paper) can be visually recognized. The transparent resin attached to the small window 107 is formed in a flat shape so that the internal certificate paper or the like can be easily machine-read in a factory or the like. However, the small window 107 can be provided with a magnifying lens portion so that the hall operator or the like can easily see the internal certificate paper or the like.

  The front door frame 13 is provided with light emitting means such as various lamps around the periphery (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 big hit or predetermined reach. For example, an annular illumination part 102 incorporating light emitting means such as LEDs is provided symmetrically along the periphery of the window part 101, and an LED or the like is provided at the center of the annular illumination part 102 and at the top of the pachinko machine 10. There is provided a central illumination unit 103 incorporating the light emitting means. In the pachinko machine 10, the central lighting unit 103 functions as a jackpot lamp and notifies that the jackpot is being hit by performing lighting or blinking in the jackpot state. Further, around the upper plate 23, there is also provided an upper plate illumination unit 104 that also incorporates light emitting means such as LEDs. In addition, on the left and right sides of the central illumination unit 103, there are respectively provided a prize ball lamp 105 that is lit during award ball payout and an error display lamp 106 that is lit when a predetermined error occurs. The annular illumination part 102 includes an inner and outer double resin cover layer and a light emitting body (LED) with a launch plate accommodated inside the resin cover layer. The inner surface of each resin cover layer intersects with each layer vertically and horizontally. A protrusion (or a wavy protrusion) is provided in the direction to be turned. The outer resin cover layer is transparent, and the inner resin cover layer is colored. Therefore, if the annular illumination part 102 is caused to emit light, it is possible to realize the illumination in a state of being dispersed in a large number or in a state accompanied with a stereoscopic effect. A resin material containing glass powder may be used for the resin cover layer. Such a configuration of the resin cover layer can also be applied to other electric decoration parts (for example, the central electric decoration part 103 and the prize ball lamp 105).

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and a card frequency check can be performed by the lending operation unit 120 in a state where a bill or a card is inserted into a card unit (a ball lending unit) arranged on the side of the pachinko machine 10. it can. That is, 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 paid out as long as the remaining amount exists on the card or the like. 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. In a pachinko machine (so-called cash machine) in which game balls are rented directly from a ball lending device or the like to a top plate without using a card unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is attached to 120 installation portions. Thereby, in the configuration of the present pachinko machine 10 provided with the lending operation unit 120, the pachinko machine using a card unit (so-called CR machine) and the cash machine can be shared.

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 13, reinforcing plates 131, 132, 133, and 134 are respectively attached to the back side of the front door frame 13 and on the left and right and upper and lower outer 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. Thereby, the closed loop of the electric path by the reinforcing plates 131 to 134 is cut, and the generation of a magnetic field causing noise is prevented.

  As shown in FIG. 13, the mounting plate 151, 152 is attached to the upper and lower ends of the reinforcing plate 131 on the opening / closing axis side that is the right side of FIG. And the assembly | attachment metal fittings 151 and 152 by the side of the front door frame 13 are attached with respect to the support metal fittings 81 and 82 (refer FIG. 3) by the side of the main body frame 12. FIG. That is, a shaft hole that opens to the lower surface is formed in the lower mounting bracket 152, and the protruding shaft 84 of the lower support bracket 82 is inserted into the shaft hole, while the upper mounting bracket 151 By inserting the shaft portion into the support hole 83 of the upper support fitting 81, the front door frame 13 is supported to be openable and closable with respect to the main body frame 12. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, even in the pachinko machine 10 in which the front door frame 13 is configured in a form including the upper plate 23 and the upper and lower shaft support intervals are increased, the front door frame 13 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front door frame 13 is suppressed.

  A pair of upper and lower hook metal fittings 155 and 156 having a hook shape are attached to the reinforcing plate 132 opposite to the opening / closing axis line on the left side of FIG. These metal fittings 155 and 156 extend rearward and are provided so as to correspond to the insertion holes 87 and 88 (see FIG. 3) provided in the main body frame 12. When the front door frame 13 is closed with respect to the main body frame 12, the metal fittings 155 and 156 are inserted into the insertion holes 87 and 88 on the main body frame 12 side, and are locked by the locking device.

  A resin case 136 is attached to the lower reinforcing plate 134 at a position facing the firing rail 61. The resin case 136 accommodates a circuit board for the ball rental operation unit 120. The back surface of the resin case 136 (the surface visible in FIG. 13) is flat, and forms the side wall of the firing rail 61 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 61.

  A ball passage rod 138 is installed at a part of the lower reinforcing plate 134 cut out toward the back of the pachinko machine 10, and at least above the ball passage rod 138, also at the back of the pachinko machine 10. An eaves portion 139 extending toward the surface is provided. In this case, in a state where the front door frame 13 is closed on the main body frame 12 side, a ridge extending along the upper side of the communication port 72 on the main body frame 12 side enters between the ball passage rod 138 and the collar portion 139. Arranged. Therefore, even if a wire, a film, or the like is invaded from the ball passage rod 138 and an illegal act is attempted, it is very difficult to infiltrate the wire, the film, or the like into the game area. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented.

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and the inside of these reinforcing plates 131 to 134 is folded back to form a glass holding groove. Two rows of glass holding grooves are formed in the front and rear, 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 according to the present embodiment, the game area is expanded. Therefore, when the front door frame 13 is closed, the ball guide formed between the inner and outer rail portions 51 and 52 is used. A part of the passage is covered by the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near 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 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of being caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a 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 spherical guide passage, and covers a section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 13 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137. A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

  Further, on the lower back side of the rail cover 140, a ridge 142 extending in an arc shape along the inner edge and protruding rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 13 is closed. Therefore, for example, even if a wire or a film is intruded through a gap between the front door frame 13 and the main body frame 12 to carry out an illegal act, the wire or the film is intruded into a game area inside the ball guide passage. Becomes very difficult. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented. The protrusion 142 may be formed in a wider range, for example, along the entire area of the inner edge of the rail cover 140. According to such a configuration, it becomes difficult to infiltrate a wire, a film, or the like in a wider range, It is possible to more reliably prevent fraudulent acts that are performed using wires or films.

  Next, the configuration of the back surface of the pachinko machine 10 will be described. FIG. 14 is a rear view of the pachinko machine 10, and FIG.

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described.

In the present embodiment, the various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. The apparatus 312 (launch control board) and the power supply apparatus 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units, and are provided with a support shaft part in a part to form the main body frame 12. Or it has the composition which can be developed to the back of game board 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 16, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Yes. Further, the back pack unit 203 is disposed in a region partially overlapping with the first control board unit 201.

  The first control board unit 201 is provided with a support shaft part M1 at the left end as viewed from the back of the pachinko machine 10, and the first control board unit 201 can be rotated around the axis A by the support shaft part M1. ing. Further, the first control board unit 201 is provided with a fastening portion M2 made of Nylatch (registered trademark) on the right end portion thereof, that is, on the open end side opposite to the support shaft portion M1, and at the upper end portion with a locking claw. A portion M3 is provided, and the first control board unit 201 is held along the back surface of the main body of the pachinko machine 10 by the fastening portion M2 and the locking claw portion M3. Further, the second control board unit 202 is provided with a support shaft part M4 at the right end when viewed from the back of the pachinko machine 10, and the second control board unit 202 can be rotated around the axis B by the support shaft part M4. It has become. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like on the left end portion thereof, that is, the open end side opposite to the support shaft portion M4, and the second control board unit 202 performs the second control. The substrate unit 202 is held in a state along the back surface of the pachinko machine 10 main body. Further, the back pack unit 203 is provided with a support shaft portion M6 at the right end when viewed from the back of the pachinko machine 10, and the back pack unit 203 is rotatable about an axis C by the support shaft portion M6. . Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like on the left end portion thereof, that is, on the open end side opposite to the support shaft portion M6, and at the upper end portion and the lower end portion, respectively, a rotating engagement member. Stop portions M8 and M9 are provided, and the back pack unit 203 is held along the back surface of the pachinko machine 10 main body by the fastening portions M7 and the locking portions M8 and M9.

  The support shaft portions M1, M4, and M6 that rotatably support the units 201 to 203 have a hinge structure that can be easily removed while the units 201 to 203 are opened from the back surface of the pachinko machine 10. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3, rotating the unit 201 around the axis A, and expanding the unit 201. Lift in condition. Thereby, if there is no backpack unit 203, the first control board unit 201 can be removed. Further, with respect to the second control board unit 202, the fastening of the fastening portion M5 is released, the unit 202 is rotated about the axis B, is unfolded, and is lifted in that state. Thereby, the 2nd control board unit 202 can be removed.

In this case, since the first control board unit 201 is partially overlapped with the back pack unit 203, it is impossible to remove the first control board unit 201 without opening the back pack unit 203. Furthermore, since the first control board unit 201 and the back pack unit 203 are configured to expand in opposite directions, the back pack unit 203 must be opened largely beyond a predetermined angle or the unit 203 must be removed. For example, the first control board unit 201 cannot be removed. Accordingly, when attention is paid to removing the first control board unit 201, it is difficult to remove compared to the other units 202 and 203. Furthermore, since the back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation of the locking device, the first control board unit 201 is further removed. Has become difficult. A more specific configuration will be described later.

Configured. The substrate box 273 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 so as not to be unsealed by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

  As long as the sealing unit 274 is configured to connect the box base and the box cover so that they cannot be opened, any configuration can be applied. Here, as shown in FIG. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit 274 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation quickly and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. 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 274. When the substrate box 273 is opened, such as when a failure occurs in the accommodated main substrate or when the main substrate is inspected, the connection between the sealing member into which the locking claw is inserted and the other sealing member is 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 substrate box 273 is left in the substrate box 273, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 273.

  The sound lamp control device 272 includes, for example, a CPU for controlling sound and lamp display in accordance with instructions from the main control device 271 or the display control device 214, and a sound lamp control board including ROM, RAM, various ports, and the like.

  The mounting base 251 is made of a synthetic resin such as a polycarbonate resin, and is colored opaque, for example, green or blue. However, the mounting base 251 may be colorless and transparent or translucent. Two flat substrate mounting surfaces 252 and 253 are provided on the surface of the mounting base 251. These substrate mounting surfaces 252 and 253 extend in a direction orthogonal to the length and breadth, and are formed with a step in the front-rear direction. Standing portions 254 erected from the substrate mounting surface 252 are integrally formed on the upper edge portion and the lower edge portion of the substrate mounting surface 252, respectively. The main controller 271 is disposed on the horizontally long substrate mounting surface 252 and the sound lamp controller 272 is disposed on the vertically long substrate mounting surface 253. At this time, the upper and lower sides of main controller 271 are supported by upright portions 254. The sound lamp control device 172 is fixed to the board mounting surface 253 with screws or the like at a plurality of locations.

  Here, as shown in FIGS. 23 and 24, the substrate mounting surface 252 is formed with horizontally elongated through holes 256 at two positions on the left and right. On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally operable fixtures 277 at two places on the left and right sides of the back surface thereof. When the main controller 271 is mounted on the board mounting surface 252, the main control board 271 is placed so that the fixing tool 277 is inserted into the through hole 256 of the board mounting surface 252, and the fixing tool 277 is placed in this state. The main control device 271 is locked by the turning operation. Accordingly, since the main control device 271 cannot be removed unless the lock 277 is unlocked from the back side of the first control board unit 201, a deterrent effect such as board removal can be obtained.

  In addition, in the mounting base 251, a shielding portion 257 for shielding an opening leading to the back space of the substrate mounting surface 252 is provided below the substrate mounting surface 252 for the main substrate. Accordingly, it is possible to prevent a hand or the like from being inserted into the back surface of the mounting base 251 from below the substrate mounting surface 252 so that the locked state of the fixture 277 cannot be illegally released. Further, when the first control board unit 201 is mounted on the back surface of the pachinko machine 10, the upper portion of the unit 201 is covered with the back pack unit 203, so that it is also prevented that a hand or the like is inserted into the back surface of the mounting base 251. The locked state of the fixture 277 cannot be illegally released.

  As described above, the first control board unit 201 cannot be removed unless the back pack unit 203 is opened at a predetermined angle or larger, or the unit 203 is not removed. The backpack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation. That is, if the main body frame 12 cannot be opened, the first control board unit 201 cannot be rotated or removed as a result, and the main controller 271 cannot be removed. Therefore, unauthorized replacement or theft of the main controller 271 can be effectively prevented.

  The main control device 271 is arranged on the front side when viewed from the back of the pachinko machine 10, and the sound lamp control device 272 is arranged 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 271 and 272 are mounted in a state where the main controller 271 and the sound lamp controller 272 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with part of them stacked one after the other. That is, as can be seen in FIG. 22 and the like, the main controller 271 is arranged in a state where a part thereof (about １ ／ in the present embodiment) is floated. Therefore, the voice lamp control device 272 can be extended to a region overlapping the main control device 271. From another viewpoint, the main control device 271 can be extended to a region overlapping the voice lamp control device 272. Even within the limited size of the pachinko machine 10, it is possible to satisfactorily cope with the increase in size of the control boards 271 and 272, and the control devices 271 and 272 can be installed efficiently. Further, when the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252 so that the variable winning device 32 and its electric wiring can be installed without difficulty. Note that lattice-like ribs 258 are provided on the back surface of the substrate mounting surface 252 to enhance the support strength of the main control substrate 271.

  A pair of upper and lower retaining pins 261 are provided on the left end surface of the mounting base 251, and the first control board unit 201 is rotated with respect to the game board 30 by attaching the retaining pins 261 to the bearing fitting 231.

The area of the pachinko machine 10 can be restored to the state before the power cut-off based on the information in the backup area 503a when the power is turned on (including power-on due to power failure cancellation). Yes. Writing to the backup area 503a is executed when the power is shut off by the NMI interrupt process (see FIG. 43), and restoration of each value written to the backup area 503a is executed in the main process (see FIG. 36) when the power is turned on. Note that the power failure signal SG1 from the power failure monitoring circuit 542 is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 501 when the power is interrupted due to the occurrence of a power failure or the like. The NMI interrupt process as a process is immediately executed.

  An input / output port 505 is connected to the CPU 501 of the main control device 271 via a bus line 504 including an address bus and a data bus. The input / output port 505 is connected to a RAM erasing switch circuit 543, a payout control device 311, a display control device 214, and other switches not shown.

The CPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the CPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

  The RAM 513 of the payout control device 311 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 313 even after the power of the pachinko machine 10 is shut off, like the RAM 503 of the main control device 271. The RAM 513 is provided with a backup area 513a in addition to a memory and an area for temporarily storing various data.

  The backup area 513a is an area for storing the stack pointer, each register, I / O, and the like when the power is shut down when the power is shut down due to a power failure or the like. Based on the information in the backup area 513a, the state of the pachinko machine 10 can be restored to the state before the power is shut off. Writing to the backup area 513a is executed when the power is shut off by the NMI interrupt process, and restoration of each value written to the backup area 513a is executed in the main process when the power is turned on. As with the CPU 501 of the main controller 271, the power failure signal SG1 is input from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 when the power is interrupted due to the occurrence of a power failure or the like. The NMI interrupt process is immediately executed.

  An input / output port 515 is connected to the CPU 511 of the payout control device 311 via a bus line 514 including an address bus and a data bus. A RAM erase switch circuit 543, a main control device 271, a firing control device 312, a payout motor 358a, and the like are connected to the input / output port 515, respectively.

  The launch control device 312 permits or prohibits the launch of the game ball by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. 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 game ball launch handle 18, and a launch for stopping the launch. On condition that the stop switch is not operated, the launch motor 229 is driven, and the game ball is launched with a strength corresponding to the operation amount of the game ball launch handle 18.

  Based on the symbol display command transmitted from the main controller 271, the display control device 214 displays the variation of the first symbol (special symbol) on the first symbol display device 41 and the second symbol (second symbol on the second symbol display device 42). This is to control the variation display of normal symbols. However, the configuration related to the display control of the first symbol of the display control device 214 will be described later. In addition, the display control device 214 transmits a control command to the audio lamp control device 272. The audio lamp control device 272 controls various lamps and speakers according to the control command received from the display control device 214, 1 The drive of the right door 171 and the left door 172 provided on the display screen of the symbol display device 41 is controlled.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit 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 circuit 543 connected to the RAM erase switch 323. And. The power supply unit 541 supplies necessary operating power to the main control device 271 and the payout control device 311 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 271 and the payout control device 311. 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 SG1 to each NMI terminal of the CPU 501 of the main control device 271 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. When this voltage becomes less than 22 volts, it is determined that a power failure (power shutdown) occurs. The power failure signal SG1 is output to the main controller 271 and the payout controller 311. Based on the output of the power failure signal SG1, the main controller 271 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 541 outputs the output of 5 volts, which is the drive voltage of the control system, to a normal value for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain. Therefore, the main control device 271 and the payout control device 311 can normally execute and complete the NMI interrupt processing.

  The RAM erase switch circuit 543 receives a switch signal of the RAM erase switch 323, and outputs a RAM erase signal SG2 for clearing backup data of the main controller 271 and the payout controller 311 in accordance with the state of the switch 323. It is. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SG2 to the main controller 271 and the payout controller 311. Thereby, when the power of the pachinko machine 10 is turned on while the RAM erase switch 323 is pressed, the data in the backup areas 503a and 513a is cleared in the main controller 271 and the payout controller 311.

  Next, the structure concerning the display control of the first symbol (special symbol) of the display control device 214 will be described with reference to FIG.

  As shown in FIG. 32, the display control device 214 includes a CPU 521, a program ROM 522, a work RAM 523, a video display processor (VDP) 524, a video RAM 525, a character ROM 526, and an input port 527. The CPU 521 of the display control device 214 receives the symbol display command (stop symbol command, variation pattern command, confirmation command, etc.) transmitted from the main control device 271 via the input port 527 and analyzes the received command or Based on the received command, predetermined arithmetic processing is performed to control the VDP 524 (specifically, generation of an internal command for the VDP 524). The program ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and also stores and holds JPEG format image data for background images. The work RAM 523 is a memory for temporarily storing work data, flags, and the like used when the CPU 521 executes various programs.

  The VDP 524 is a kind of drawing circuit that directly operates an LCD driver (liquid crystal driving circuit) incorporated in the first symbol display device 41. Since the VDP 524 is formed as an IC chip, it is also called a “drawing chip”, and the substance of the VDP 524 can be said to be a microcomputer chip with a dedicated firmware for drawing processing. The VDP 524 adjusts the respective timings of the CPU 521, the video RAM 525, etc. to intervene in reading and writing data, and reads display data stored in the video RAM 525 from the character ROM 526 at a predetermined timing to the first symbol display device 41. Display.

  The video RAM 525 is a memory for storing display data displayed on the first symbol display device 41, and the display contents of the first symbol display device 41 are changed by rewriting the contents of the video RAM 525. The character ROM 526 plays a role as an image data library for storing character data such as symbols displayed on the first symbol display device 41. The character ROM 526 holds bitmap format image data of various display patterns, a color palette table to be referred to when determining the expression color of each dot of the bitmap image, and the like. In particular, a symbol code (symbol number) is assigned to each symbol image data in the bitmap format, and each symbol image can be managed only by the symbol code at the command level. Note that a plurality of character ROMs 526 may be provided, and image data and the like may be stored in each character ROM 526 in a shared manner. Further, it is also possible to store the JPEG format image data for the background image stored in the program ROM 522 in the character ROM 526.

  Here, the 1st symbol displayed on the 1st symbol display apparatus 41 and the display content on the display screen in the 1st symbol display apparatus 41 are demonstrated based on FIG. 33, FIG. FIG. 33 is a drawing individually showing a plurality of symbols as the first symbol. FIG. 34 is a diagram showing the display screen G of the first symbol display device 41, where (a) shows the area division setting and effective line setting in the display screen G, and (b) shows the actual symbol. Show the display contents.

  As shown in (a) to (k) of FIG. 33, the first symbol is composed of 10 types of main symbols with numbers “0” to “9” and one type of petal-shaped symbols. It consists of sub-designs. Specifically, in each main symbol, numbers “0” to “9” are attached on the rear symbol made of a wooden box, of which the odd symbols (1, 3, 5, 7, 9) Each numerical number is assigned to the front side of the wooden box. On the other hand, in the main symbols of even numbers (0, 2, 4, 6, 8), each of the main symbols beside the attached symbols such as amulet, furoshiki, helmet, bag, kettle drawn on the front side of the wooden box. Numeric numbers are relatively small. In this case, the main symbol to which the odd number (1, 3, 5, 7, 9) is attached corresponds to the “high probability symbol”, and when the high probability symbol is aligned, the big game state that is a special gaming state is entered, Thereafter, the state shifts to a state with a high probability. In addition, the main symbol with an even number (0, 2, 4, 6, 8) corresponds to a “low probability symbol”, and when the low probability symbol is aligned, it shifts to a jackpot state. It does not shift to the state at the time of high probability. The high probability means a state in which the combination of the first symbol becomes a big hit by a predetermined combination of probability fluctuation symbols and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state.

  The player plays the game with the expectation that the first symbol is aligned with a high probability symbol, that is, the number attached to the main symbol when the fluctuation of the first symbol is stopped is a high probability number (odd number). In the high-probability symbol, the numerical symbol is drawn large and it is emphasized that the probability is high. Therefore, the interest of the game is enhanced.

  Next, the display screen G of the first symbol display device 41 will be described. As shown in FIG. 34 (a), the display screen G of the first symbol display device 41 is roughly divided into two vertically, and the lower 2/3 is the main display region Rm that displays the first symbol variably, and the others. (Upper 1/3) is a sub display area Rs for displaying a notice effect and a character. The main display area Rm corresponds to the “first display area”, and the sub display area Rs corresponds to the “second display area”.

  In the main display area Rm, three symbol rows Z1, Z2, and Z3 of left, middle, and right are set, and the above-described first symbols are displayed in a prescribed order for each of the symbol rows Z1 to Z3. . That is, in each of the symbol rows Z1 to Z3, the main symbols are arranged in ascending or descending numerical order, and one sub symbol is arranged between the main symbols. At this time, a total of 20 first symbols of 10 main symbols and 10 sub symbols are set in each of the symbol rows Z1 to Z3. In the main display area Rm, 20 first symbols are variably displayed so as to scroll from top to bottom with periodicity for each symbol row Z1 to Z3. In particular, the numbers of main symbols appear in descending order in the left symbol row Z1, and the numbers of main symbols appear in ascending order in the middle symbol row Z2 and the right symbol row Z3. In the main display area Rm, the first symbols are displayed in the upper, middle, and lower three rows for each of the symbol rows Z1 to Z3. As a result, a total of nine first symbols in three rows × three rows are displayed. It has come to be.

  In the main display area Rm, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set. In each game, the variable display of the first symbol is stopped in the order of the left symbol column Z1 → the right symbol column Z3 → the middle symbol column Z2, and when the symbol is confirmed, the first symbol is a big hit on any active line. If a combination of symbols (in this embodiment, the same combination of main symbols) is arranged, a jackpot moving image is displayed as a jackpot.

  The sub display area Rs is horizontally long above the main display area Rm, and is further equally divided into three areas. In this case, of the three areas of the sub display area Rs, the right area is the first notice area Rs1, the left area is the second notice area Rs2, and the center area is the third notice area Rs3. The first warning area Rs1 and the second warning area Rs2 are areas that overlap the right door 171 and the left door 172 (see FIG. 9) described above. The first notice area Rs1 is hidden by the right door 171 and the second notice area Rs2 is hidden by the left door 172. On the other hand, the third notice area Rs3 does not overlap the right door 171 and the left door 172, and is a display area that can always be viewed by the player.

  On the actual display screen, as shown in FIG. 34B, a total of nine main symbols and sub symbols of the first symbol are displayed in the main display region Rm. The figure shows an arbitrary display state. Further, in the sub display area Rs, when the right door 171 and the left door 172 are disposed, the first notice area Rs1 and the second notice area Rs2 are hidden, and the display contents cannot be visually recognized. When the right door 171 is opened, the first notice area Rs1 appears, and a predetermined notice effect is performed in the first notice area Rs1. In addition, the second notice area Rs2 appears when the left door 172 is opened, and a predetermined notice effect is performed in the second notice area Rs2. In the third warning area Rs3, a display is normally performed so that a predetermined character (a boy character with a bee stick in the figure) performs a predetermined operation. And the notice effect by the said character etc. is performed as needed.

  As described above, the display screen G of the first symbol display device 41 is divided into the main display region Rm and the sub display region Rs in principle, but it straddles each display region Rm, Rs, or A display effect can also be performed by integrating at least a part of the main display area Rm and the sub display area Rs. For example, after a predetermined reach occurs, the display area Rm and Rs are combined into one display area by eliminating the area division of the main display area Rm and the sub display area Rs, and display effects using the display area are achieved. Done. However, the display form after the occurrence of reach will be described in detail later.

  Incidentally, in the present embodiment, the right door 171 and the left door 172 cannot be seen through the back, but for example, the right door 171 and the left door 172 are made of a translucent material, and the right door 171 and the left door 172 The image behind the door 172 may be blurred or slightly transparent. In this case, even in a state hidden behind the right door 171 and the left door 172, display effects are performed in the first notice area Rs1 and the second notice area Rs2. Then, even if the first notice area Rs1 and the second notice area Rs2 are concealed by the right door 171 and the left door 172, the player can expect the expectation to shift to the big hit state by slightly seeing the effects behind them. Can be given to

  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 271 uses various counter information during the game to perform jackpot lottery, setting the symbol display of the first symbol display device 41, and the like. Specifically, As shown in FIG. 35, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 41, and the first symbol display device 41 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, a game ball to the operation port 33 is provided. According to the winning history, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are stored in time series.

  For details of each counter, the jackpot random number counter C1 is configured so that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI is a loop counter similar to the big hit random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the values are “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot symbol counter C2 determines the symbol at the time of fluctuation stop of the first symbol display device 41 in the case of a jackpot, and in the present embodiment, the first symbol display device 41 has five effective lines, Since ten specific symbols (main symbols) are set, 50 counter values (0 to 49) are prepared. That is, the jackpot symbol counter C2 is incremented by 1 within a range of 0 to 49, and reaches a maximum value (that is, 49) and then returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by one before and after the reach symbol, and the last stop symbol after the reach has also occurred. “Reach other than front / rear out” and stop “completely out” where no reach occurs, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to the reach other than the front and rear deviation, and C3 = 22 to 238 corresponds to the complete deviation. The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 41, the number of suspended 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 operation port 33.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented one by one within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). 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 the first symbol such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the first symbol display device 41 starts the variation of the first symbol.

  The left, middle and right off symbol counters CL, CM, and CR determine the stop symbol of the left row 1st symbol, the middle row 1st symbol, the right row 1st symbol when the big hit lottery is missed. In each column, any one of the 20 first symbols in total including the main symbol and the sub symbol is displayed, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle, and lower symbols are determined by the out symbol counter CL, the upper, middle, and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The top, middle and bottom symbols are determined.

  In the present embodiment, the values of the counters CL, CM, and CR are randomly updated by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, 20 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 first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier, and the completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second symbol random number counter C4 is used for the lottery of the second symbol display device 42. The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 in the main controller 271 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is roughly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and power failure to the NMI terminal (non-maskable terminal). There is NMI interrupt processing activated by signal input. For convenience of explanation, first, timer interrupt processing and NMI interrupt processing will be described, and then main processing will be described.

  FIG. 41 is a flowchart showing timer interrupt processing. This processing is executed by the CPU 501 of the main controller 271 every 2 msec, for example.

  In FIG. 41, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 271 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in step S602, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in 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 the subsequent step S603, the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in this 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.

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. The start winning process will be described with reference to the flowchart of FIG. 42. In step S701, whether or not the game ball has won the start opening (start winning) is determined based on the detection information of the operation opening switch 224. When it is determined that the game ball has won the operating port 33, in the subsequent step S702, it is determined whether or not the number N of active reserved balls of the first symbol display device 41 is less than the upper limit value (4 in the present embodiment). Determine. The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In the subsequent step S704, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in the step S603 are stored in the first area in 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 interrupt process.

  In addition, when the game ball wins the operating port 33 (start winning prize), the first symbol display display on the first symbol display device 41 is started accordingly, but after the start winning, the first symbol changes. However, there is a restriction that a predetermined time (for example, 5 seconds) must elapse before the symbol is stopped. Therefore, in the start winning process, when the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S704). Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses). .

  FIG. 43 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power supply of the pachinko machine 10 is cut off due to the occurrence of a power failure, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 43 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt processing, in step S801, the used register is saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the information on occurrence of power interruption is set in the backup area 503a, and in step S804, a power interruption notification command indicating that the power has been interrupted is transmitted to another control device. In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. Thereafter, an infinite loop is entered in preparation for the power supply being completely shut down and the processing being impossible.

  The above NMI interrupt processing is executed in the same manner in the payout control device 311, and the state of the payout control device 311 when the power is shut down due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513 by the NMI interrupt. Similarly, 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 SG1 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 SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 43 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 36 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 271, and this main process is started with a reset at power-on.

  In the main process, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (audio lamp control device 272, payout control device 311, etc.) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311. In subsequent step S103, RAM access is permitted.

  Thereafter, data backup processing is executed for the RAM 503 in the CPU 501. That is, in step S104, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed, and in subsequent step S105, it is determined whether or not the information on occurrence of power shutdown is set in the backup area 503a of the RAM 503. To do. In step S106, a RAM determination value is calculated. In subsequent step S107, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. Note that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 323. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to a RAM initialization process (steps S114 to S116). Similarly, when the information on occurrence of power shutdown 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 (steps S114 to S116) of the RAM 503 in the same manner. . That is, in step S114, the use area of the RAM 503 is cleared to 0, and in the subsequent step S115, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when power is restored). That is, in step S108, the stack pointer before power-off is restored, and in step S109, information on occurrence of power-off is cleared. In step S110, a command for returning the sub-side control device to the gaming state at the time of power-off is transmitted, and in step S111, the used register is returned from the backup area 503a of the RAM 503. In steps S112 and S113, the interrupt permission / non-permission is returned to the state before the power shutdown, and then the address before the power shutdown is returned.

  Next, the flow of normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, the processing of steps S201 to S207 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S209 and S210 is executed with the remaining time.

  In the normal process, 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. In addition, when the first symbol display device 41 displays the variation of the first symbol, a display command such as a stop symbol command, a variation pattern command, and a confirmation command is transmitted to the display control device 214. In addition, after the start of the fluctuation of the first symbol, one each time in the normal process in order of the fluctuation pattern command → the left symbol row stop symbol command → the middle symbol row stop symbol command → the right symbol row stop symbol command The command is transmitted once every 4 msec), and the confirmation command is transmitted at the timing when the fluctuation time elapses.

  Next, in step S202, the variation type counters CS1 and CS2 are updated. Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503. In subsequent step S203, updating of each outlier symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  The update process of each outlier symbol counter CL, CM, CR will be described. As shown in FIG. 38, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. It is determined whether or not it is time to update the symbol counter CM that is out of the symbol row. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. On the other hand, if it is time to update the middle symbol sequence (YES in step S302), the process proceeds to step S304 to update the out-of-middle symbol counter CM. Further, if the update timing of the right symbol sequence (both NO in steps S301 and S302), the process proceeds to step S305, and the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR. According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, in step S306, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination. If the symbol combination is a jackpot symbol combination, the process is terminated. If it is not a jackpot symbol combination, it is determined in step S307 whether or not it is a reach symbol combination, and if it is a reach symbol combination, in step S308 it is further determined whether or not it is a front-rear reach. To do. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S309, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear outreach symbol buffer of the RAM 503. If the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step S310, 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. . If the combination of outlier symbol counters CL, CM, CR is not a jackpot symbol combination and not a reach symbol combination (when both S306 and S307 are NO), this is a combination of outlier symbol counters CL, CM, CR In this case, the process proceeds to step S 311, and the combination of the off symbol counters CL, CM, CR at that time is stored in the complete off symbol buffer of the RAM 503.

  After update processing of the off symbol counters CL, CM, CR, in step S204 in FIG. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed. By this first symbol variation process, jackpot determination, setting of a variation pattern of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

  Thereafter, in step S206, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 35 in the case of the big win state is executed. That is, it is determined whether the big winning opening is opened for each round in the big win state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, display control of the second symbol (for example, a normal symbol of “◯” or “x”) by the second symbol display device 42 is executed. Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second symbol random number counter C4 is acquired each time and the second symbol is displayed on the display unit 45 of the second symbol display device 42. Is displayed. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the operating port 33 is released for a predetermined time. Although the description is omitted, the second symbol random number counter C4 is also updated by the timer interrupt process shown in FIG. 41, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3.

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. Then, the random number initial value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in 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 step S210, update of the variation type counters CS1 and CS2 is executed. 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.

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the jackpot random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The variation type counters CS1 and CS2 can also be updated at random.

  Next, the first symbol variation process of step S205 will be described with reference to the flowcharts of FIGS.

  In the first symbol variation process, in step S401, it is determined whether or not a big hit is currently being made. Note that the jackpot includes the jackpot game displayed on the first symbol display device 41 in the jackpot and the middle of a predetermined time after the jackpot game ends. In a succeeding step S402, it is determined whether or not the first symbol display device 41 is displaying the variation of the first symbol. Then, when it is not a big hit and is not displaying the variation of the first symbol, the process proceeds to step S403, and it is determined whether or not the number N of active suspension balls of the first symbol display device 41 is larger than zero. Then, when the jackpot is being hit or the number N of operation-reserved balls is 0, this processing is terminated as it is.

  If neither the big hit or the change in the first symbol is being displayed and if the number N of activated balls is> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of active suspension balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, the first symbol variation start process is executed. Here, the details of the variation start process will be described using the flowchart of FIG. 40. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. "601, 661" is the winning value.

  If it is determined that the game is a jackpot, in step S502, a table corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (value of the jackpot symbol counter C2). And a symbol representing the corresponding relationship between the symbol and the symbol, and the symbol is set as a stop symbol command. At this time, the numbers 0 to 49 of the jackpot symbol counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. When these jackpot symbols are gathered with a predetermined specific symbol, the state changes to a probability variation state. However, when the symbols are not specific symbols (non-specific symbols), the probability variation state is not entered.

  Next, in step S503, the variation pattern of the first symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach type such as normal reach, super reach, premium reach, and other rough types are determined based on the value of the first variation type counter CS1. And the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) More detailed pattern variation modes are determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set or to set a pattern with both values of both variation type counters CS1 and CS2 is appropriately determined according to the value of the first variation type counter CS1 and the game conditions each time. The same applies to the setting of the fluctuation pattern in the case of performing front / rear out of reach display, reach display other than front / rear out, and complete out of display described later.

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

  If front / rear out of reach has occurred, the process proceeds to step S506, and the left, middle, and right out of symbol counters CL, CM, and CR stored in the front / rear out of reach design buffer of the RAM 503 are set as stop symbol commands. Also, in step S507, a variation pattern for front / rear out of reach display is determined, and the variation pattern is set as a variation pattern command. At this time, as in step S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. The reach type (such as the middle symbol in the present embodiment) is stopped after the occurrence of the reach based on the value of the second variation type counter CS2 In other words, a more detailed symbol variation mode such as the number of variation symbols) is determined.

  If a reach other than front / rear out occurs, the process proceeds to step S508, and the left, middle, and right outreach counters CL, CM, and CR stored in the reach symbol buffer other than front / rear out of RAM 503 are set as stop symbol commands. To do. In step S509, a variation pattern for reach display other than front / rear deviation is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like.

  If it is neither big hit nor reach, the process proceeds to step S510, and the left, middle, and right off symbol counters CL, CM, and CR stored in the complete off symbol buffer of the RAM 503 are set as stop symbol commands. In step S511, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like. As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, at the time of reach occurrence, or at the time of no reach occurrence, this processing is terminated.

  Returning to the description of FIG. 39, if step S402 is YES, that is, if the variation of the first symbol is being displayed, the process proceeds to step S407 to determine whether or not the variation time has elapsed. At this time, the variation time of the first symbol is determined according to the variation pattern of the first symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a confirmation command set for confirming the stop symbol is set, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 44 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, a predetermined value determined in advance is set in the stack pointer, and an interrupt mode is set. In step S902, the process waits until a payout permission command transmitted from main controller 271 is received. When the payout permission command is received, the process advances to step S903 to permit RAM access, and in step S904, an external interrupt vector is set.

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

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

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

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

  In FIG. 45, in step S1001, a command from the main controller 271 is acquired and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 16. That is, when the lower pan 16 is determined to be full 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 is full , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed 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. When there is no tank ball, the tank ball no state setting is executed. Perform configuration.

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

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not payable and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009, and a prize to be described later shown in FIG. Start the ball control process. If the prize ball is not paid out or the total number of prize balls is 0 (YES in any of steps S1007 and S1008), the process proceeds to the lending / paying process in steps S1010 to S1012.

  In the rental ball payout process, if the rental ball is not in a disabled state and a rental ball payout request is received from the card unit (NO in step S1010, YES in S1011), the process proceeds to step S1012 and is shown in FIG. The ball rental control process described later is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), subsequent ball removal processing is executed.

  In step S1013, the payout motor 358a is driven to execute the ball removal process on the condition that the state return switch 321 is checked and the ball removal disabled state is not set and the ball removal operation is not started. In subsequent step 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. 46, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, where the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

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

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

  In the ball lending control process shown in FIG. 47, in step S1201, the payout motor 358a is driven to pay out the lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 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 in FIG.

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

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

  Next, a specific procedure of display control by the display control device 214 will be outlined. FIG. 48 is a flowchart showing display control processing executed by the CPU 521 in the display control device 214. The CPU 521 executes display control of the first symbol display device 41 while processing various commands provided from the main control device 271 according to the procedure shown in FIG.

  In FIG. 48, first, in step S1301, it is determined whether or not a display command is received from the main controller 271. When step S1301 is NO, it waits until it receives some command. When the display command is received, the process proceeds to step S1302, and the contents of the display command are stored in the work RAM 523. In step S1303, various arithmetic processes such as generating an internal command for the VDP 524 are started based on the information stored in the work RAM 523. As a result, the VDP 524 performs a drawing process in response to a command (internal command) from the CPU 521 and starts the variable display of symbols on the first symbol display device 41. At this time, the CPU 521 outputs a control command for driving voices and lamps and a control command for operating the right door 171 and the left door 172 while synchronizing with the display effects at each time. Send to. As a result, the sound lamp control device 272 drives the right door 171 and the left door 172 in addition to the sounds and lamps in accordance with the control command from the CPU 521. It should be noted that the symbol variation display is continued under the cooperation of the CPU 521 and the VDP 524 until the display command is received once until the confirmation command is received thereafter. Meanwhile, the CPU 521 performs the control of the VDP 524 and the command reception process shown in FIG. 48 in parallel. The control in the sound lamp control device 272 is the same.

  Thereafter, in step S1304, it is determined whether or not a confirmation command has been received from main controller 271. Then, the process proceeds to step S1305 on the condition that the confirmation command has been received, and instructs the VDP 524 to confirm the display with the stop symbol. As a result, the VDP 524 confirms and displays the changed symbol as a stop symbol. In this way, one round of display processing is performed from the start of change of the symbol to the stop of change (definite display). The display control device 214 is controlled by the main control device 271 at the time of starting and stopping the change of the symbol, but the continuous change of the symbol during that time is a self-supporting image by the CPU 521 and the VDP 524 in the display control device 214. Secured by control.

  Next, in the display control by the display control device 214, a specific example will be given of what display is actually performed when reach occurs and how the right door 171 and the left door 172 operate on the display screen. explain. 49 to 54 show display examples showing the display screens of the first symbol display device 41 in various reach patterns. Here, six types of reach patterns from pattern 1 to pattern 6 are illustrated. Of these, pattern 1 is a reach pattern called normal reach, and patterns 2 to pattern 6 are reach patterns called super reach. is there.

  In the pattern 1 shown in FIG. 49, both the right door 171 and the left door 172 remain closed, and the main display area Rm and the sub display area Rs remain divided into two areas. In this case, the background screen in the main display area Rm is not changed from that in the normal state, and the variable display of the final stop symbol (the symbol in the middle symbol row) is performed in substantially the same manner as in the normal state.

  In the pattern 2 shown in FIG. 50, the right door 171 and the left door 172 are both closed, but the main display area Rm and the sub display area Rs are separated, and the center of the main display area Rm and the sub display area Rs is removed. The reach effect is performed using the area (the third notice area Rs3 described in FIG. 34). In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a girl character with petals in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. The final stop pattern fluctuates while repeating expansion and contraction.

  In the pattern 3 shown in FIG. 51, the right door 171 is opened and the left door 172 is closed. Also, the main display area Rm and the sub display area Rs are separated from each other, and the right display area and the central area of the main display area Rm and the sub display area Rs (first and third notice areas Rs1, Rs3 described in FIG. 34). And reach production. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character riding a crane truck in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. The final stop symbol changes while being lifted by a crane.

  In the pattern 4 shown in FIG. 52, the right door 171 is closed and the left door 172 is opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and the left area and the center area of the main display area Rm and the sub display area Rs (second and third notice areas Rs2 and Rs3 described in FIG. 34) And reach production. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character who operates the conveyor in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) appears in that display state. Is displayed. The final stop symbol fluctuates while being moved in the horizontal direction by being placed on the conveyor in the left side region and the central region (second and third notice regions Rs2, Rs3 described in FIG. 34) of the original sub display region Rs.

  In the pattern 5 shown in FIG. 53, the right door 171 and the left door 172 are both opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and a reach effect is performed using the main display area Rm and the entire sub display area Rs. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character with a mallet and a girl character staring at it) appears, and the final stop pattern is displayed in that state. The change display of (the symbol in the middle symbol row) is performed. The final stop symbol moves from top to bottom and fluctuates while being beaten one by one with a mallet.

  Finally, in the pattern 6 shown in FIG. 54, the right door 171 and the left door 172 are both opened. In addition, the main display area Rm and the sub display area Rs are separated from each other, and a reach effect is performed using the main display area Rm and the entire sub display area Rs. In this case, the background screen is changed to something different from the normal screen, and a reach effect character (a boy character with a wooden mallet in the figure) appears, and the final stop symbol (the symbol in the middle symbol row) is displayed. ) Is displayed. In particular, in such pattern 6, the number of effective lines is increased from the normal number of 5 lines, and the degree of expectation for shifting to the big hit state is increased. The final stop symbol moves from top to bottom and fluctuates while being beaten one by one with a mallet.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A front guide path 595 and a rear guide path 596 are provided on the stage surface FS of the stage member 590 provided on the game board 30, and a game ball is guided toward the operation port 33 from both the front side and the rear side of the stage surface FS. The configuration was made possible. Therefore, for example, when the pachinko machine 10 is installed in an island facility in a game hall, even if the pachinko machine 10 is inclined to some extent in the front-rear direction, the front guide path 595 or the rear guide path 596 is moved to the operation port 33. Thus, there is no inconvenience that the game ball is guided and the probability of entering the operation port 33 is remarkably lowered.

  In addition, since the front guide path 595 and the rear guide path 596 are integrally formed with the stage member 590, the front guide path 595 and the rear guide path 596 can be easily formed, and the above effect can be achieved with a relatively simple configuration. be able to. Furthermore, the game balls can be distributed in the front-rear direction on the stage surface FS.

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

  (A) In the above embodiment, as the front guide part and the rear guide part, the front guide path 595 and the rear guide path 596, which are inclined surfaces inclined downward toward the front and rear, respectively, are continuously provided. However, this may be changed. For example, as shown in FIG. 55A, a configuration in which a horizontal plane 599 exists between the rear end portion of the front guide path 595 and the front end portion of the rear guide path 596 may be employed. In this case, when the game ball sufficiently decelerated at the top of the mountain portion 594a of the stage surface FS passes through the trajectory of the dotted line A or B, the front guide path 595 or the rear guide path 596 leads to the operation port 33. However, when passing through the trajectory of the dotted line C, it is led out from the horizontal plane 599 to the valley portion 594b and is not guided toward the working port 33. Therefore, in this configuration, compared with the above-described embodiment, the ball entering the working port 33 is less likely to occur, but the behavior of the game ball at the top of the mountain portion 594a can be diversified. Moreover, as shown in FIG.55 (b), the structure which provides the front hole part 649 and the rear hole part 650 which penetrated to the up-down direction instead of the front guide path 595 and the back guide path 596 may be sufficient. Further, as illustrated, the front hole 649 may be reduced and the rear hole 650 may be increased. In this case, the game ball that has reached the holes 649 and 650 falls substantially downward without passing over the holes 649 and 650, so that the game on the stage surface FS is compared to the above embodiment. The rolling mode of the sphere is reduced. On the other hand, the proportion of game balls guided from the stage surface FS toward the operation port 33 is increased. In this configuration, since the game ball is led out from the front hole portion 649 and the rear hole portion 650 to the concave portion 614, the ball passage 593 is not necessary.

  (B) In the above embodiment, the length of the front guide path 595 is shorter than the length of the rear guide path 596, but this may be changed. For example, the front guide path 595 and the rear guide path 596 may have the same length, or the length of the front guide path 595 may be longer than the length of the rear guide path 596. In this case, the probability of entering the operation port 33 is slightly lower than that in the above embodiment.

  (C) In the above embodiment, the front guide path 595 and the rear guide path 596 are provided by being integrally formed with the stage member 590, but this may be changed. For example, the stage member 590 may be provided with a guide path mounting portion, and a guide path member including a front guide path 595 and a rear guide path 596 may be attached to the guide path mounting portion. In this case, without changing the design of the stage member 590, it is possible to change aspects such as the shapes of the front guide path 595 and the rear guide path 596 only by changing the design of the guide path member. The probability of entering the operation port 33 from the surface FS can also be changed.

  (D) In the above embodiment, the stage surface FS has a width of about two game balls. However, any structure can be used as long as it has a width of one or more game balls. May be. Therefore, for example, the width may be about 1.5 gaming balls or about 3 gaming balls.

  (E) In the above-described embodiment, the stage surface FS is a mountain portion 594a with a substantially central portion rising upward, and further, a valley portion 594b in which the left and right sides of the mountain portion 594a are recessed downward. The left and right ends have a shape positioned above the central portion, but the same effect can be obtained even in a stage surface FS that does not have this shape. For example, the stage may be provided with a stage surface that is curved along the left-right direction and has a substantially arc shape that protrudes downward at a substantially central portion. However, in this configuration, the front guide path 595, the rear guide path 596, the notch 613b, and the ball path 593 are arranged at the lowest position on the stage surface. The game balls are easily guided to the front guide path 595 or the rear guide path 596, and as a result, the ball entering the operation port 33 is easily generated.

  (F) In the above embodiment, the stage member 590 has a structure having two rolling surfaces, that is, the upper surface of the upper stage 591 and the upper surface of the lower stage 594 (stage surface FS). Also good. For example, the stage member 590 may have a configuration including three, four, five, or six or more rolling surfaces. In this case, the behavior of the game ball on the stage member 590 can be diversified, and the game entertainment can be improved. Further, the stage member 590 may have a configuration having only one rolling surface.

  (G) In the above-described embodiment, the game balls that have been driven up above the center frame 43 are guided to the stage surface FS by guiding means such as the upper ball passage 601, the front and rear ball passages 631, and the side ball passages 551. The pachinko machine 10 provided with the guiding means having a configuration other than the above may be used. For example, a configuration in which guiding means is provided only on both sides of the center frame 43 may be employed. In this case, the game ball is guided from the periphery of both sides of the center frame 43 to the stage surface FS. Moreover, the structure which is not provided with a guidance means may be sufficient. In this case, derivation of the game ball to the stage surface FS is performed by a nail or the like disposed on the game board 30. Therefore, in this configuration, the probability of derivation of the game ball to the stage surface FS is lower than in the above embodiment.

  (H) In the above embodiment, the stage member 590 is fixed to the center frame 43 and, as a result, fixed to the game board 30, but this may be changed. For example, the structure provided with the angle adjustment means which can adjust the assembly | attachment angle with respect to the game board 30 of the stage member 590 may be sufficient. In this case, when the pachinko machine 10 is assembled in the island facility of the game hall, even if a tilt in the front-rear direction or the left-right direction occurs, the influence of the tilt on the stage member 590 can be easily reduced.

  (I) Moreover, the structure which provides the angle adjustment means of the structure of said (h) so that a player can operate may be sufficient. In this case, the front guiding path 595 or the rear guiding path where the player can easily enter the operating hole 33 by operating the angle adjusting means while visually recognizing the rolling mode of the game ball on the stage surface FS. The player can guide the game ball to 596 himself. Thereby, means for operating the rolling of the game ball can be provided in addition to the conventional game ball launching handle, so that it is possible to improve the game entertainment.

  (J) In the above embodiment, the stage member 590 is provided as a part of the center frame 43, but the stage member 590 and the center frame 43 may be provided as separate members. For example, the left and right side portions and the upper portion of the center frame 43 of the above embodiment and the lower portion of the center frame 43 may be separate members. In this case, the stage member 590 can be attached to and detached from the game board 30 independently of the center frame 43. Thereby, the maintainability of the stage member 590 is improved.

  (K) In the above embodiment, the front guide path 595 and the rear guide path 596 are configured to guide the game ball toward the operation port 33, but may be changed. For example, it may be configured to guide the game ball toward the general winning award 31 or the like.

  (L) In the above embodiment, the game area is formed by the game board 30 made of a substantially rectangular plywood in which a large number of nails and windmills 37 are arranged. Any configuration may be used as long as the game area is formed by being arranged. For example, the game area may be formed by a configuration using an electronic paper or the like that can display a transparent resin or a moving image. Electronic paper is an electronic display that is thin, light, and bent like paper.

  (M) In the above embodiment, the pair of front and rear glasses 137 are attached to the front door frame 13, but any material may be adopted as long as it has predetermined transparency. For example, “resin plate” may be employed instead of “glass”.

  (N) In the above-described embodiment, the pachinko machine 10 having a relatively large game area as compared with the conventional game machine has been described. It can also be applied to. Further, the invention can be applied to other types of ball game machines different from the above-described embodiment, for example, game machines such as a pachinko machine, an arrange ball machine, and a sparrow ball provided with other objects.
