  Note that most of the lower dish unit 13 is molded of ABS resin in the same manner as the inner frame 12. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost. In particular, the surface layer forming the lower plate 15 and the front panel portion at the back of the lower plate are formed of flame retardant ABS resin. For this reason, this part is difficult to burn.

  As shown in FIG. 2, the front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 has an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It can be opened to the front side with an axial center. Moreover, the front frame set 14 is attached so as to fit into the outer wall (rib) 12b (see FIG. 3) of the inner frame 12. That is, since at least a part of the side surface of the front frame set 14 is attached so as to fit into the outer wall (rib) 12b of the inner frame 12, foreign matter (from the gap between the inner frame 12 and the front frame set 14) Such as a needle or thin plate) can be prevented. Further, since the front frame set 14 is made of a synthetic resin, specifically, an ABS resin, like the inner frame 12, the front frame set 14 is highly viscous and strong against impact, and can be manufactured at low cost.

  On the other hand, an upper plate 19 as a receiving tray for game balls is integrally provided below the front frame set 14 (above the lower plate 15). Here, the upper plate 19 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device 38 while aligning them in a line. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame set, and an upper plate is provided on the front decorative frame. The upper plate 19 is provided directly to the front frame set 14 and is omitted. Similar to the lower plate 15, the upper plate 19 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  Here, the front frame set 14 is provided below the pachinko machine 10 so as not to interfere with at least the game ball launching handle 18. The dimension (H1 in FIG. 1) to the lower end of the front frame set 14 is, for example, about 201 mm in one existing model, but is about 172 mm, which is about 30 mm smaller in the pachinko machine 10. In addition, along with this, the dimension from the lower end of the pachinko machine 10 to the upper plate 19 (H2 in FIG. 1) is also reduced, and in the existing model, for example, it is about 298 mm, whereas in this pachinko machine 10, it is 261 mm. It has become. In such a configuration, there is a concern that the distance between the nozzle portion of the ball lending device and the upper plate 19 will increase due to the lowering of the position of the upper plate 19, and the spilled gaming balls will be rented. A part of the peripheral wall of the upper plate 19 was raised at a portion (left side portion) that receives the game ball from the nozzle portion (the high wall portion 19a in FIG. 1). Thereby, even if it has the structure which lowered the position of the top plate 19, inconveniences, such as spilling out of a rental game ball, are eliminated. In addition, the height dimension of the high wall part 19a should just be commensurate with the down dimension of the upper plate 19, and was 25 mm in the present Example.

  As shown in FIG. 3, the inner frame 12 is mainly composed of a resin base 20 having a rectangular outer shape, and a substantially circular window hole 21 is formed at the center of the resin base 20. A game board 30 is detachably mounted on the rear side of the resin base 20. The game board 30 is made of a rectangular plywood and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, the substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The game board 30 has a vertical length of 476 mm and a horizontal length of 452 mm (same size as before).

  Next, the configuration of the game board 30 will be described with reference to FIG. FIG. 4 is a front view showing the configuration of the game board 30. The game board 30 includes a general winning port 31, a variable winning device 32, a first starting port 33 (for example, an operation chucker), a second starting port 34 (for example, a through gate), a variable display unit 35, and the like. These general winning port 31, variable winning device 32, first starting port 33 (for example, operation chucker), second starting port 34 (for example, through gate), variable display unit 35, etc. It is arranged in each through hole formed by machining, and is attached from the front side of the game board 30 with wood screws or the like. A game ball enters the above-described general winning port 31, variable winning device 32, and first starting port 33, and the detected balls are described later (a winning port switch 221, a count switch 223, an operating port switch 224, etc.). Based on the output of the detection switch, a predetermined number of prize balls are paid out to the upper plate 19 (or the lower plate 15). In addition, the game board 30 is provided with an out port 36, so that game balls that have not entered the various winning devices etc. are guided through the out port 36 toward a ball discharge path (not shown). It has become. A number of nails are planted in the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display device unit 35 variably displays a first symbol (for example, a special symbol) as identification information on the first symbol display unit 43a of the display screen 43 by using a winning at the first start port 33 as a trigger. A display device 42 that variably displays a second symbol (for example, a normal symbol) on the second symbol display unit 43 b of the display screen 43 using the passage of the two start ports 34 as a trigger is provided.

  The display device 42 is configured as a liquid crystal display device, and display contents (various display contents including the first symbol and the second symbol) are controlled by a display control device 45 described later. In the second symbol display section 43b of the display screen 43 of the display device 42, as shown in FIG. 4, for example, the second symbols represented by “◯” and “x” are variably displayed. Further, the center frame 47 includes a plurality of (four in this embodiment) hold lamps 44 indicating the hold of the variation display of the second symbol. Each time the game ball passes through the second start opening 34, for example, the second symbol (ordinary symbol) of the second symbol display unit 43b of the display device 42 fluctuates, and the first symbol is displayed when the variation display stops at a predetermined symbol. The starting port 33 is configured to be activated (opened) for a predetermined time. The number of times that the game ball has passed through the second start opening 34 is held up to a maximum of 4 times, and the number of times the game ball is held is lit and displayed by the hold lamp 44. The hold lamp 44 may be configured to be variably displayed on a part of the display device 42 in addition to a configuration that is variably displayed by switching lighting of a plurality of lamps. In addition, the 2nd symbol display part 43b of the display apparatus 42 mentioned above corresponds to the normal identification information fluctuation | variation display means in this invention.

  In addition, in the first symbol display portion 43a of the display screen 43 of the display device 42, for example, three symbol rows of left, middle, and right are displayed. Each symbol row is composed of a plurality of symbols, and these symbols are variably displayed on the display device 42 so as to be scrolled for each symbol row. In the present embodiment, the display device 42 (liquid crystal display device) includes a large liquid crystal display having an 8-inch size. A center frame 47 is disposed in the variable display device unit 35 so as to surround the display device 42. The display device 42 described above corresponds to the fluctuation display means in the present invention, the first symbol display portion 43a of the display device 42 described above corresponds to the identification information fluctuation display means in the present invention, and the display control device 45 described above is provided. This corresponds to the display control means in the present invention.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is repeatedly operated between an open state in which a game ball is easy to win and a normal closed state in a big win. ing. More specifically, when a game ball wins the first start port 33, the display device 42 displays the first symbol in a variable manner, and the final symbol after the stop needs to be a combination of specific symbols set in advance. A special gaming state occurs in the condition. The large winning opening of the variable winning device 32 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win a prize (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times. The number of times that the game ball has passed through the first start port 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 46. Note that the hold lamp 46 may be configured to be variably displayed on a part of the display device 42.

  In addition, the 1st symbol is for granting a profit for the player in a special gaming state, and the 2nd symbol is a profit smaller than the 1st symbol (a benefit of opening the first start port 33). It is for granting.

  The game board 30 is also provided with a rail unit 50 for guiding the game ball launched from the game ball launching device 38 to the upper part of the game board 30, and is released in accordance with the turning operation of the game ball launch handle 18. The played game balls are guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a product molded by adding a fluororesin), and has an inner rail 51 and an outer rail 52 integrally formed in an inner and outer double. . In addition, since the rail unit 50 is shape | molded by adding a fluororesin, it can reduce the frictional resistance of the game ball about the back surface 50a shown in FIG. The inner rail 51 is formed in a substantially annular shape except for about ¼ of the upper part, and the outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a spherical guide passage is formed by a portion (the left portion facing) where the rails 51 and 52 are parallel to each other at a predetermined interval. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 51 and the outer rail 52 to the upper part of the game board 30 returns to the ball guide path again. Yes. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail 52). Accordingly, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner surface of the outer rail 52, there is a sliding plate 55 as a long metal strip made of stainless steel in order to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is attached.

  An arc-shaped flange 56 projecting outward is formed on the outer peripheral portion of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, 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. In this embodiment, in order to firmly fasten at least the left side of the rail unit 50 to the game board 30, the left side of the rail unit 50 is fastened to the game board 30 with more screws than the right side. Adhesiveness to the game board 30 on the left side can be improved, and a game ball can be improved. This is because if the left side of the rail unit 50 is wobbled with respect to the game board 30, the momentum of the game ball emitted to the rail unit 50 is absorbed by the wobble.

  Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially straight line (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50, and the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and a foul ball that does not reach the game area and flows backward in the ball guide passage is used as a foul ball passage 63 (see FIG. 3). Play a role in guiding. Note that the lower right corner and the lower left corner of the game board 30 are spaces for attaching stickers (for example, S1 and S2 in FIG. 4) and plates such as stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 4) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

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

  In the present embodiment, the game area is a region surrounded by the inner rail 51 and the outer rail 52 as viewed from the front of the pachinko machine 10, except for a guide rail region that is a parallel part of the inner and outer rails 51 and 52. As an area. Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail 52 but by the inner rail 51. Similarly, the right limit position toward the game area is specified by the inner rail 51. The lower limit position of the game area is specified by the lower end position of the game board 30. The upper limit position of the game area is specified by the outer rail 52.

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

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

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

  Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 10 is about 40%, which is a much larger area ratio than in the past. 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 addition, the 2nd starting port 34 located in the both sides of the variable display apparatus unit 35 has a guide mechanism in which the game ball which passed this 2nd starting port 34 is approached toward the center. Thereby, even when the game area is expanded in the left-right direction, the game ball can be guided toward the center first starting port 33 and the variable prize-winning device 32. By expanding, it is possible to suppress a decrease in interest due to difficulty in winning game balls. Furthermore, by extending the game area in the left-right direction, various arrangements of the windmill 37, the second start port 34, a plurality of nails (guide nails for guiding the game ball to the center), and other accessories are arranged. Thus, the behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. In addition, since the game area is also expanded in the vertical direction, various windmills 37, second start ports 34, a plurality of nails, and other accessories can be further arranged in the vertical direction in the game area. The behavior of the game ball can be made even more interesting.

  Returning to the description of FIG. 3, in the resin base 20, below the window hole 21 (game board 30), a launch rail 61 for guiding the game ball immediately after being launched from the game ball launcher 38 is attached. ing. The firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (injection angle). Accordingly, a game ball that is launched in accordance with the turning operation of the game ball launching handle 18 is first launched obliquely upward along the launch rail 61, and thereafter, into the predetermined game area through the ball guide passage of the rail unit 50 as described above. Guided.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded as compared with the prior art, but under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered, and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than that of the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launcher 38 can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 61 is formed to extend from the launch position of the game ball launcher 38 to a position beyond the center position (out port 36) of the game area.

  In addition, there is a predetermined gap between the firing rail 61 and the rail unit 50 (guide rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball launched from the game ball launching device 38 does not reach the return ball prevention member 53 and returns to the inside of the guide rail as a foul ball, the foul ball passes through the foul ball passage 63 to the lower plate. 15 is discharged. Incidentally, in the case of the present embodiment, the length of the firing rail 61 is about 240 mm, and the length of the gap at the tip of the firing rail (the length on the extension line of the firing rail 61) is about 40 mm.

  When the foul spheres flow backward in the guide rail, most of them flow along the outer rail 52 and fall downward when reaching the lower end of the outer rail 52. There is also a thing that jumps 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 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. This suppresses interference between the foul ball and the next game ball to be launched.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). . At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large. Guide members 65 and 66 were installed on the front side. Thereby, the game ball supplied from the ball exit on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device 38 is provided with an electromagnetic game ball launching unit 228 to be described later so that the game ball is launched with a strength corresponding to the amount of operation of the game ball launching handle 18.

  In addition, the code | symbol 67 in FIG. 3 is the discharge port connected to the upper plate 19, and a game ball is discharged to the upper plate 19 through this discharge port 67. FIG. The discharge port 67 is provided with an openable / closable shutter 68 that is displaced between a substantially horizontal state and a substantially vertical state with a substantially horizontal rotation axis as an axis. When the front frame set 14 is released from the inner frame 12 (the state shown in FIG. 3), the shutter 68 is changed from a substantially horizontal state to a substantially vertical state by an urging force of a spring or the like. The discharge port 67 is closed. When the front frame set 14 is closed, the shutter 68 is pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14 to be in a substantially horizontal state. The game ball discharged toward the direction passes through the ball passage ridge 69 and is discharged to the upper plate 19 without any leakage. Therefore, in the pachinko machine 10 in which the front decorative frame is omitted and the upper plate 19 is directly provided to the front frame set 14, the game balls in the payout passage and the like are outside the pachinko machine 10 when the front frame set 14 is opened. Inconveniences such as spilling out can be prevented.

  The resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Therefore, a sticker such as a stamp (S1 in FIG. 4) stretched at the lower right corner of the game board 30 can be seen through the small window 71. Further, a sticker or the like can be pasted from the small window 71.

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

  As shown in FIG. 3, a front frame set open detection switch 90 that detects that the front frame set 14 is opened with respect to the inner frame 12 is provided above the inner frame 12. When the front frame set 14 is opened, it is output from the front frame set open detection switch 90 to the computer for the hall (in the pachinko parlor). When the front frame set 14 is closed, the metal reinforcing plates 132 and 131 of the front frame set 14 shown in FIG. 5 come into contact with the pair of metal fittings 92 of the inner frame 12 shown in FIG. The grounding of the front frame set 14 is secured.

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

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

  In addition, the front frame set 14 is provided with light emitting means such as various lamps in the periphery (for example, 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, at the periphery of the window portion 101, an annular illumination portion 102 containing light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks when the jackpot is informed that the jackpot is being hit. Further, an upper plate illumination part 104 that also includes a light emitting means such as an LED is provided around the upper plate 19. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. In addition, a small window 107 made of a transparent resin is provided so as to be adjacent to the lower end portion of the annular illumination portion 102 so that a part of the inner frame 12 surface, the game board 30 surface, or the like can be visually recognized. Since the predetermined portion of the small window 107 is flat, the certificate paper or the like attached to the lower right corner of the game board 30 can be suitably read from the flat portion of the small window 107 by a machine.

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

  Further, as shown in FIG. 1, the vicinity of the small window 107 on the left side of the front frame set 14 is prevented from protruding more than necessary to the front side (the front side of the paper in FIG. 1). Thus, when a game ball is lent directly to the upper plate 19 from the card sand ball lending device provided on the left side of the pachinko machine 10, the tip of the nose portion of the ball lending device (so-called elephant nose) is discharged. An exit can be suitably located in the upper position of the top plate 19, and the game ball lent from the nose part of the said ball lending apparatus can be received by the top plate 19. FIG.

  Various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcing plates 131, 132, 133, and 134 are attached to the back side of the front frame set 14 and on the top, bottom, left and right sides of the window portion 101, respectively. 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. Thus, since the resin part 135 is interposed in the connection part of the reinforcement boards 132 and 133, it can prevent that a noise loops with the reinforcement boards 131-134. Further, the right reinforcing plate 131 in FIG. 5 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is formed on the inner frame 12 with the front frame set 14 closed. It is configured to be engaged with the hole 12a (see FIG. 3). With this configuration, the front frame set 14 is configured to include the upper plate 19, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

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

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

  As described above, in the pachinko machine 10 according to the present embodiment, the game area is expanded. The part is covered with the front frame set 14. Therefore, in the guide rail, a portion where the open side on the front side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device 38 returns without reaching the return ball prevention member 53, the game ball spills (jumps out) from the guide rail, the outer rail 52 and the glass. 137. Therefore, in the present embodiment, the rail cover 140 for covering the front side open portion of the guide rail is attached to the front frame set 14.

  The rail cover 140 is a substantially flat plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has a circular arc shape corresponding to the shape of the guide rail, and covers the section from the base end portion of the guide rail to the vicinity of the tip end portion along the peripheral edge of the window portion 101. It is attached to the back side of the set 14. In particular, the dimensions and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail 52. When the rail cover 140 is attached, the surface side of the rail cover 140 is in contact with the glass 137. In a state where the front frame set 14 is closed, the back surface of the rail cover 140 covers almost the entire area of the guide rail. Thereby, the collision of the game ball with the glass 137 can be prevented in most sections of the guide rail. Therefore, adverse effects such as breakage due to contact with the glass 137 can be suppressed.

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

  Further, on the back side of the rail cover 140, a ridge 142 is formed that extends in an arc shape along the inner edge of the rail cover 140 and protrudes toward the front side of FIG. The ridge 142 is configured to overlap the inner rail 52 almost integrally with the rim 142 in a state of entering the guide rail when the front frame set 14 is closed. Therefore, for example, even if a wire or the like is invaded through the gap between the front frame set 14 and the inner frame 12 to perform a fraudulent act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. In addition, it is good also as a structure which forms the protrusion 142 in a wider range, for example along the whole region of the inner edge of the rail cover 140. According to this structure, it becomes difficult to infiltrate a wire etc. in a wider range, a wire etc. It is possible to more reliably prevent fraudulent acts that are performed using.

  Further, support brackets 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Therefore, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side. It comes to be installed.

  Next, the configuration of the back surface of the pachinko machine 10 will be described in detail. FIG. 6 is a rear view of the pachinko machine 10, and FIG. 7 is an exploded perspective view showing the rear structure of the pachinko machine 10 for each major part.

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

  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. It is configured to be openable and closable with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  Actually, as shown in the schematic diagram of FIG. 8, the units 201 to 203 are arranged and attached. In FIG. 8, 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.

The first control board unit 201 is fixedly held to the main body of the pachinko machine by the fastening part M2 and the locking claw part 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 opens and closes around the axis B by the support shaft part M4. It is possible. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like at the left end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side). 2 The control board unit 202 is fixedly held to the pachinko machine 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 can be opened and closed around an axis C by the support shaft portion M6. Yes. Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like at the left end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side), and the upper end portion and the lower end portion are respectively rotatable. , And the back pack unit 203 is fixedly held to the main body of the pachinko machine by the fastening part M7 and the locking parts M8, M9.

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

  On the other hand, FIG. 9 is a rear view showing the configuration in a state where the game board 30 is assembled to the inner frame 12. FIG. 10 is a perspective view of the inner frame 12 as viewed from the rear, and FIG. 11 is a perspective view of the game board 30 as viewed from the rear. Here, the back side structure of the inner frame 12 and the game board 30 will be described with reference to FIGS.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 20 and is not dropped by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated to switch between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a locked state. The locking fixtures 211 at the three left and right sides of the game board 30 are L-shaped brackets formed by bending metal pieces, and are configured not to protrude outward from the inner frame when the game board 30 is fixed. Note that the locking fixture 212 at one lower portion of the game board 30 is an I-shaped fastener made of resin.

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

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, corresponding to the above-described game board opening of the general winning opening 31, the variable winning apparatus 32, and the first starting opening 33 (see FIG. 3 respectively), and 1 on the downstream side. A collection passage 216 that collects at a place is formed. Further, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is attached to the inner frame 12 below the game board 30, and a discharge ball is sent to the outside of the pachinko machine 10 in the discharge passage board 217. A discharge passage 218 for guiding is formed. Therefore, as illustrated in phantom lines in FIG. 9, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further the discharge passage 218 of the discharge passage board 217. Through the pachinko machine 10. In addition, the out port 36 (see FIG. 3) similarly communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

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

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

  In addition, on the back side of the game board 30, a winning detection mechanism for detecting the passage of gaming balls such as various winning holes is provided. Specifically, a prize opening switch 221 is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and a specific area switch 222 and a count switch 223 are provided in the variable prize winning device 32. The specific area switch 222 is a switch for determining that a game ball won in the variable winning device 32 in the big hit state has entered a specific area (an area for determining whether or not to continue the big hit state), and the count switch 223 displays the winning ball. It is a switch that counts. An operation port switch 224 is provided at a position corresponding to the first start port 33, and a gate switch 225 is provided at a position corresponding to the second start port 34. The operating port switch 224 described above corresponds to the winning detection means in the present invention.

  The prize opening switch 221 and the gate switch 225 are connected to the board relay board 226 through electric wiring (not shown), and this board relay board 226 is connected to a main board (main control device) described later. Further, the specific area switch 222 and the count switch 223 are connected to the special winning opening relay board 227, and the special winning opening relay board 227 is also connected to the main board. On the other hand, the operation port switch 224 is directly connected to the main board without passing through the relay board.

  Although not shown in the drawings, the variable winning device 32 is provided with a large winning opening solenoid for opening the large winning opening and a winning ball sorting plate solenoid for guiding the winning ball to a specific area. The start port 33 is provided with an operation port solenoid for opening the electric accessory. In FIG. 9, reference numeral 228 denotes an electromagnetic game ball launcher.

  The detection results detected by the winning detection mechanism are taken into the main board, which will be described later, and a payout command (the number of game balls to be paid out) corresponding to the winning situation is sent from the main board to the payout control board. The Then, a predetermined number of game balls are paid out by the output of the payout control board. In such a case, a conventional method (so-called evidence ball method) in which game balls won at various winning openings are once collected in a winning ball processing device, and the winning ball processing device confirms the presence of the winning balls one by one and then pays out one by one. Unlike the above, the pachinko machine 10 according to the present embodiment electrically senses the winning of a game ball at each winning opening and immediately pays out (that is, the pachinko machine 10 abolishes the winning ball processing device). doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

  The back frame set 215 is provided with an attachment mechanism for attaching the first control board unit 201. Specifically, as this attachment mechanism, a support bracket 231 extending in the vertical direction is provided at the lower left corner when viewed from the back surface of the game board 30, and the support bracket 231 has a pair of upper and lower support holes 231a on the same axis.

  Further, an attachment mechanism for attaching the second control board unit 202 and the back pack unit 203 is provided on the back surface of the inner frame 12. Specifically, a long support fitting 235 is attached to the inner frame 12 at its right end, and its configuration is shown in FIG. As shown in FIG. 12, the support metal fitting 235 has a long plate-like metal fitting body 236, and the support hole 237 for the second control board unit is formed at two lower positions so as to stand up from the metal fitting body 236. At the same time, support hole portions 238 for the back pack unit are formed at two locations above. Coaxial support holes are formed in the support hole portions 237 and 238, respectively. In addition, as an attachment mechanism for the second control board unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (ny latch holes) 239 at the left end below the game board installation area. In addition, as an attachment mechanism for the back pack unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (ny latch holes) 240 at the left end portion of the game board installation area. However, the support bracket for the second control board unit and the support bracket for the back pack unit can be provided as separate members. Reference numerals 241, 242, and 243 denote rotational fixtures for sandwiching and supporting the back pack unit 203 with the game board 30.

  In addition, in the rear configuration of the inner frame 12, a game ball paid out from a payout mechanism 352 described later is distributed to any one of the upper plate 19, the lower plate 15, and the discharge passage 218 in the lower right portion of the game board 30. A game ball distribution unit 245 is provided. That is, the opening 245 a of the game ball distribution unit 245 communicates with the upper plate 19, the opening 245 b communicates with the lower plate 15, and the opening 245 c communicates with the discharge passage 218. As shown in FIGS. 10 and 20, the game ball distribution unit 245 is separated from a later-described payout mechanism unit 352 located above the game ball distribution unit 245. As shown in FIG. 10, the game ball distributing unit 245 is fastened and fixed to the inner frame 12 with screws, and inserts foreign objects from the discharge port 67 (see FIG. 3) of the upper plate 19 of the pachinko machine 10. Even if the game ball distribution unit 245 is pushed to the back side, there is no gap between the game ball distribution unit 245 and the inner frame 12, and a foreign object is inserted into the gap. It can prevent fraud.

  In addition, a resin speaker box 246 for enclosing the back of the speaker 24 installed on the lower plate 15 is attached to the lower end portion of the inner frame 12. It has been.

  Next, the first control board unit 201 will be described with reference to FIGS. 13 is a front view of the first control board unit 201, FIG. 14 is a perspective view of the unit 201, FIG. 15 is an exploded perspective view of the unit 201, and FIG. 16 is an exploded perspective view of the unit 201 viewed from the back. .

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

  As the sealing unit 264 as the sealing means, any configuration can be applied as long as the box base and the box cover are connected so as not to be opened, but here, as shown in FIG. 14 and the like, five sealing members are connected. The box base and the box cover are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 263 is left in the substrate box 263, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 263.

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

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

  The main control device 261 (main substrate) is arranged in a landscape orientation on one board mounting surface 252 and the audio lamp control device 262 (audio lamp control board) is arranged in a portrait orientation on the other substrate mounting surface 253. It is arranged in the direction. In particular, the main control device 261 is disposed on the near side as viewed from the back of the pachinko machine 10, and the sound lamp control device 262 is disposed on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 261 and 262 are mounted with the main controller 261 and the sound lamp controller 262 mounted on the substrate mounting surfaces 252 and 253. Are arranged with a part of them stacked one after the other. That is, as can be seen in FIG. 14 and the like, the main controller 261 is arranged in a state where a part thereof (about １ ／ in the present embodiment) is floated. Therefore, the sound lamp control device 262 can be extended to an area overlapping with the main control device 261, and the enlargement of the control board can be dealt with satisfactorily. In addition, each control device 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.

  As shown in FIGS. 15 and 16, the board mounting surface 252 for the main board is formed with horizontally elongated through holes 254 at two places on the left and right. Correspondingly, the substrate box 263 of the main control device 261 is provided with rotational fixing tools 267 at two places on the left and right sides of the back surface thereof. When the main controller 261 is mounted on the board mounting surface 252, the fixing tool 267 is passed through the through hole 254 of the board mounting surface 252, and the fixing tool 267 is rotated in this state to lock the main control apparatus 261. The Therefore, even if the main control device 261 is arranged in a state where it floats as described above, inconveniences such as dropping off of the main control device 261 can be avoided. The main controller 261 opens the back pack unit 203 with the axis C as the axis and opens the first control board unit 201 with the axis A as the axis, and then the first control board unit 201 (the board mounting surface 252). ) Cannot be removed unless the lock 267 is unlocked from the back surface side, and therefore a deterrent effect can be expected for illegal actions such as board removal. A grid-like rib 255 is provided on the back surface of the substrate mounting surface 252 for the main substrate.

  The mounting base 251 is provided with a pair of upper and lower support shafts 256 on the left end surface of FIG. 14 and the like.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal S1 to each NMl terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the voltage of AC 5 volts in the power supply unit 541, and determines that a power failure (power failure) has occurred when the time when this voltage has become less than 5 volts exceeds, for example, 20 milliseconds. The power failure signal S1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal S1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute the power failure processing (NMI interrupt processing in FIG. 33).

  In addition, even after the time when the AC 5 volts monitored by the power supply unit 541 becomes less than 5 volts exceeds 20 milliseconds, the power supply unit 541 has a sufficient time to execute the power failure process. The control system is configured to maintain the output of 5 volts, which is the drive voltage of the control system, at a normal value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal S2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 613 are cleared in the main controller 261 and the payout controller 311. The

  By the way, as shown in FIG. 24, the display device (liquid crystal display device) 42 is provided with three symbol rows L, M, and R of left, middle, and right. Three symbols of the upper symbol, the middle symbol, and the lower symbol (the first symbol: for example, a special symbol) are variably displayed. In the present embodiment, the series of symbols is composed of a main symbol with numbers “0” to “9” and a sub-pattern consisting of rhombus-shaped symbols, in ascending or descending order of the numbers. A main symbol is displayed, and a sub-symbol is arranged between the main symbols to form a series of symbol rows L, M, and R. The main symbol and the sub symbol are variably displayed from top to bottom with periodicity.

  In this case, in the left symbol row L, the series of symbols is displayed in descending order (that is, in the order of decreasing the number of the main symbol), and in the middle symbol row M and the right symbol row R, the series of symbols is also in ascending order. (That is, in order of increasing main symbol numbers). Then, the variable display stops in the order of the left symbol row L → the right symbol row R → the middle symbol row M, and at the time of the stop, five effective lines on the first symbol display raid 42, that is, the upper line L1, the middle line L2, A special game video is displayed as a jackpot if the main symbol is aligned with a jackpot symbol combination (in this embodiment, the same main symbol combination) in any of the lower line L3, the rightward rising line L4, and the leftward rising line L5. It is like that.

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

  In this embodiment, the CPU 501 in the main control device 261 performs lottery (big hit lottery) of the display device 42 and setting of symbol display using various counter information in the game. 25, the jackpot random number counter C1 used for the jackpot lottery of the display device 42, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the display device 42, and the reach lottery when the display device 42 changes and changes Reach random number counter C3 used for initial value, 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 display device 42, left column, middle column And the left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the right column; To have. Each counter described above is constituted by a program executed by the CPU 501.

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

  For details of each counter, the jackpot random number counter C1 is, for example, sequentially incremented by “1” within a range of “0” to “676” and returns to “0” after reaching the maximum value (that is, “676”). It has become. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the big hit random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and updated repeatedly within the remaining time of normal processing. . The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first start port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random number values that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 289, 337, 401, 463, 523, 601, 661”. High probability means a state where the jackpot is won by a predetermined probability variation pattern and the subsequent jackpot probability is increased as added value, so-called “probability”, and normal time (low probability) is This is the time when it is not in a probable state.

  The jackpot symbol counter C2 determines the symbol at the time when the fluctuation of the display device 42 is stopped in the case of a jackpot. In the present embodiment, the display device 42 has five effective lines, and a specific symbol (main symbol). Since 10 are set, 50 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first start port 33.

  Further, the reach random number counter C3 is configured to increment one by one within a range of 0 to 238, for example, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach drawing may be set individually according to the state of the lottery probability of the display device 42, the number of operation suspension balls at the start of the 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 first start port 33.

  Further, one of the two variation type counters CS1 and CS2 is incremented by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. For example, the other variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0. In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”. The first variation type counter CS1 determines the reach type of the first symbol, such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes. 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 CS1 and CS2 are acquired when the display device 42 determines the variation pattern when the first symbol variation starts.

  The left, middle, and right out symbol counters CL, CM, and CR are stopped symbols (the first symbol in the left column, the first symbol in the middle column, and the first symbol in the right column when the big win lottery of the display device 42 is lost. Since each of the main symbols and sub-designs is displayed in each column, one of the 20 first symbols is displayed in each column, so 20 counter values (0 to 19) each. Is prepared. 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 added result exceeds the maximum value, 20 is subtracted to determine the current value. Is done. 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 start of 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

  The size and range of each counter is only an example and can be arbitrarily changed. However, it is desirable that the big hit random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case.

  Although not shown, the second symbol random number counter C4 is used for the lottery of the second symbol of the second symbol display unit 43b of the 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 the game ball passes through the second start port 34 on either the left or right side. The number of random number values to be won is 149, and the range is “5 to 153”.

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

  FIG. 31 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 261 every 2 msec, for example.

  In FIG. 31, first, in step S601, reading processing of various winning switches is executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in step S602, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In subsequent step S603, the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in this embodiment, 676, 49, and 238, respectively). Clear to 0 each. 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 first start port 33 is executed. This start winning process will be described with reference to the flowchart of FIG. 32. In step S701, whether or not the game ball has won the first start opening 33 is determined based on the detection information of the operation opening switch 224. When it is determined that the game ball has won the first start opening 33, in the subsequent step S702, it is determined whether or not the number N of operation pending balls of the display device 42 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 first start port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one.

  In subsequent step S704, a random number related to the winning of the first symbol is acquired. Specifically, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area of the free storage area of the reserved ball storage area of the RAM 503. After performing the start winning process in this way, the CPU 501 once ends the timer interrupt process.

  FIG. 33 is a flowchart showing the NMI interrupt process, and this process is executed by the CPU 501 of the main control device 261 when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503.

  That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal S1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 261. Then, the CPU 501 interrupts the control being executed and starts the NMI interrupt process of FIG. 33 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal S1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 261 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing of FIG. 33, first, in step S801, the used registers are 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 the 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 rapidly interrupted is transmitted to another control device.

  In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The NMI interrupt process is also executed in the payout control device 311 in the same manner, and the state of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Similarly, the power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal S1 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 S1 is output from the power failure monitoring circuit 542 to the NMl 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. 33 is started. The contents are as described with reference to FIG. 33 (however, the NMI interrupt processing of the payout control device 311 does not transmit the power-off notification command in step S804).

  Next, the main process will be described.

  FIG. 26 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 261. This main process is started upon reset when power is turned on.

  First, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (such as the sound lamp control device 262 and the payout control device 311) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311. In subsequent step S103, RAM access is permitted.

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

  As described above, the pachinko machine 10 is turned on while pressing the RAM erase switch 323 when it is desired to return to the initial state when the power is turned on, for example, when the hall starts business. Therefore, if the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S114, etc.). Similarly, when the information on occurrence of power interruption is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 503 (step S114 or the like). That is, in step S114, the used area of the RAM 503 is cleared to 0, and in the subsequent step S115, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal. Execute the process (process when power is restored). That is, in step S108, the stack pointer before the power interruption is restored, and in step S109, the information on the occurrence of the power interruption is cleared. In step S110, a command for causing the sub control device to return to the gaming state at the time of power-off is transmitted, and in step S111, the used register is restored from the backup area 503a of the RAM 503. Further, in steps S112 and S113, the interrupt permission / non-permission is returned to the state before the power is turned off, then the address is returned to the address before the power is turned off, and then the normal processing (see FIG. 27) described later is performed. For example, when the power is cut off after executing up to step S202 of the normal process, the process returns to the address before the power is cut off, and the process is executed from step S203 of the normal process.

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

  In FIG. 27, first, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45 when the display device 42 displays the variation of the first symbol. In addition, after the first symbol variation starts, the variable pattern command → the left symbol sequence stop symbol command → the right symbol sequence stop symbol command → the middle symbol sequence stop symbol command one by one in the order of normal processing ( In other words, one command is sent every 4 msec), and the confirmation command is sent 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 out symbol counter CL, CM, CR will be described in detail. As shown in FIG. 28, in step S301, it is determined whether or not it is time to update the out symbol counter CL in the left symbol row. In step S302, It is determined whether or not it is time to update the middle symbol row out of symbol counter CM. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both steps S301 and S302 are NO), the process proceeds to step S305, and the off symbol counter CR of the right symbol example 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 out symbol counters CL, CM, and CR is a reach symbol combination. If it is a reach symbol combination, then in step S307, it is changed back and forth. It is determined whether or not it is a missed reach. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S306, 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 symbol CL, CM, CR is a combination of reach other than front / back off, the process proceeds to step S309, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. .

  In the case of a combination other than the reach symbol, in step S310, it is determined whether or not the combination of the symbol symbols CL, CM, CR is a symbol combination, and if it is a symbol combination, Proceeding to step S311, the combination of the off symbol counters CL, CM, and CR at that time is stored in the off symbol buffer of the RAM 503. If NO in both steps S306 and S310, the symbols are aligned on the left, middle, and right, that is, it corresponds to a jackpot state. In such a case, the off symbol counters CL, CM, and CR are stored in the buffer. The process is terminated without any processing.

  After the removal symbol counter update process, in step S204 in FIG. 27, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display unit 43a of the display device 42 is executed. By this first symbol variation process, jackpot determination, variation setting 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 of the big hit 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, the second symbol variation process (variation display control) is executed by the second symbol display unit 43b of the display device. Briefly, on the condition that the game ball has passed through the second starting port 34, the second symbol random number counter C4 is acquired and the second symbol display unit 43b of the display device 42 performs the second operation. Symbol variation display is performed. Specifically, in this embodiment, “◯” and “×” as the second symbol of the display device 42 shown in FIG. 4 are alternately lit to enter the second symbol fluctuation state. Then, when the second symbol lottery is carried out based on the value of the second symbol random number counter C4 and the second symbol is hit, that is, when the symbol “○” is lit, the first start port 33 is determined. Is opened for a predetermined time. Although the description is omitted, the second symbol random number counter C4 is also updated by the timer interrupt processing shown in FIG. 31, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3. Yes.

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. Then, the random number initial value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503.

  In step S210, update of the variation type counters CS1 and CS2 is executed (same as step S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the 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, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. .

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

  In FIG. 29, in step S401, it is determined whether or not it is currently a big hit. Note that the jackpot includes a special game displayed on the display device 42 in the case of the jackpot and a predetermined time after the special game ends. In a succeeding step S402, it is determined whether or not the first symbol display unit 43a of the display device 42 is displaying the variation of the first symbol. Then, when it is not a big hit and the first symbol variation display is not in progress, the process proceeds to step S403, where it is determined whether or not the number N of active suspension balls of the first symbol display unit 43a of the display device 42 is greater than zero. At this time, if the jackpot is being hit or if the number N of working suspension balls is 0, this processing is terminated as it is.

  Further, if it is neither a big hit nor a change display of the first symbol, and if the number of operation hold balls N> 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 of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted, such as the hold first area, the hold third area → the hold second urea, the hold fourth area → the hold third area.

  Thereafter, in step S406, a fluctuation start process is executed, and thereafter, a process of calculating an average fluctuation seconds AVE (step S406A) is performed as will be described later, and this process (first symbol fluctuation process) is terminated. Here, the details of the variation start processing will be described with reference to the flowchart of FIG. 30. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Specifically, whether or not the jackpot is determined based on the relationship between the jackpot random number counter value and the mode at that time, as described above, among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, "337, “673” is the winning value, and “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” is the winning value when the probability is high.

  If it is determined that the game is a jackpot, in step S502, a table corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, a table not showing the jackpot symbol (value of the jackpot symbol counter C2). And a symbol representing the correspondence between the symbol and the symbol), and the symbol is set as a stop symbol command. At this time, 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 at the time of the big hit is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach of the first symbol such as normal reach, super reach, premium reach, etc. based on the value of the first variation type counter CS1. The type and other rough symbol variation modes are determined, and the elapsed time until the final stop symbol (in this embodiment, middle symbol) stops after the occurrence of reach based on the value of the second variation type counter CS2 (in other words, The pattern variation mode is determined in more detail, etc. 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 Are previously defined by a table or the like.

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

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

  If a reach other than front / rear out occurs, the process proceeds to step S508, and the left, middle, and right out-of-line counters CL, CM, CR stored in the reach symbol buffer other than front / rear out of RAM 503 are stopped. Set to. Also, in step S509, a fluctuation pattern at the time of reach other than front / rear deviation is determined, and the fluctuation pattern is set as a fluctuation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like.

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

  Returning to the description of FIG. 29, 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 change stop command is set as a confirmation command, and then this process ends.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 34 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. In step S902, the process waits until a payout permission command transmitted from main controller 261 is received. When the payout permission command is received, the process advances to step S903 to permit RAM access, and in step S904, an external interrupt vector is set.

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

  If the RAM erase switch 523 is ON, the process proceeds to a RAM initialization process (step S915 and the like). Similarly, when the occurrence information of power interruption is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing of the RAM 513 (step S915 or the like). That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

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

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

  In FIG. 35, in step S1001, a command from the main control device 261 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 15. That is, when the lower pan 15 is detected based on the detection signal of the lower pan full switch, when the lower pan is full, the lower pan full state is set, and when the lower pan full is not reached , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration.

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

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if it is not possible to pay out the balls and the total number of winning balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009, and a winning ball control process (described later). FIG. 36) is started. Further, if the prize ball cannot be paid out or the total number of prize balls is 0 (YES in any of steps S1007 and S1008), the process proceeds to a lending payout process.

  Thereafter, in steps S1010 to S1012, a rental ball payout process is executed. In this case, if it is not possible to pay out the rent and if a rent-out request from the card unit has been received (NO in step S1010, YES in S1011), the process proceeds to step S1012 and a renting control process (described later). FIG. 37) is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), the subsequent ball removal process is executed.

  In step S1013, the state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In subsequent step S1014, control of vibrator 360 (vibration motor control) is executed on condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  Here, in the prize ball control process shown in FIG. 36, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the dispensing motor 358a is normal is determined based on the detection result of the dispensing 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 proceeds to step S1105, where the payout motor 358a is driven to execute a retry process and the payout motor 358a is stopped, and then the process returns to the payout control process of FIG.

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, 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. 37, in step S1201, the payout motor 358a is driven to pay out a lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1203, 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 advances to step S1204 to determine whether or not the game ball is normally counted based on the detection result of the payout count switch. If the game ball count is not normal, the process advances to step S1205 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

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

  Next, the structure of the further characteristic part of the pachinko machine 10 of a present Example is demonstrated using FIG. FIG. 38 is a block diagram showing the configuration of the main controller 261 and the game ball launcher 38.

  As described above, as shown in FIG. 38, the main control device 261 requires that the variation display result of the first symbol on the display device 42 is a predetermined combination of symbols (big hit symbol). It has a function of generating a special game state. In short, the main controller 261 is based on the value (first random number) of the jackpot random number counter C1 (first random number group for determining whether or not to enter the special gaming state) that can take a value from 0 to 676. A special gaming state is generated.

  Specifically, as shown in FIG. 38, the CPU 501 of the main control device 261 has a first random number generator 400 (first random number group generation function) that generates a jackpot random number counter C1. Further, the main control device 261 stores the value of the big hit random number counter C1 in the reserved ball storage area of the RAM 503 (first random number storage unit 402) every time a game ball wins the first start port 33. It has. Further, the CPU 501 of the main control device 261 also has a first determination unit 404 (determination function) that determines whether or not the value of the big hit random number counter C1 stored in the reserved ball storage area is a win value. .

  Note that the value (first random number) of the big hit random number counter C1 in the first random number generator 400 is held in the RAM 503 at the timing of detecting the winning of the game ball by the operation port switch 224 provided in the first start port 33. It is stored in the sphere storage area (first random number storage unit 402). When the probability is low, the first determination unit 404 is a big hit if the value (first random number) of the big hit random number counter C1 stored in the first random number storage unit 402 is two values “337, 673”. If not, it is determined that it is off. Further, at the time of high probability, the first determination unit 404 determines that the value of the big hit random number counter C1 (first random number) stored in the first random number storage unit 402 has ten values “67, 131, 199, 289, 337, 401, 463, 523, 601 and 661 ", it is determined that it is a big hit, otherwise it is determined that it is off. The first random number generator 400 and the first determination unit 404 described above are realized by causing the CPU 501 to execute a predetermined program.

  When the CPU 501 determines that the value of the big hit random number counter C1 is a win value, the main control device 261 outputs a signal for setting the special gaming state to the variable winning device 32. Based on the instruction from the main control device 261, the variable winning device 32 executes a jackpot operation in which the game ball repeatedly operates in an open state and a normal closed state in which the game ball is easy to win.

  As shown in FIG. 38, the pachinko machine 10 according to the present embodiment has a game ball launch handle 18 that receives an operation related to the launch of the game ball by the player, and a game ball according to the player's operation on the game ball launch handle 18. And a game board 30 (see FIG. 4) having a game area into which the game balls launched by the game ball launching apparatus 38 are driven.

  The game ball launch handle 18 includes a handle operation signal output unit 406 that outputs an electrical signal corresponding to the player's operation amount with respect to the game ball launch handle 18 when an operation related to the game ball launch is received by the player. .

  For example, when the player rotates the game ball launch handle 18 greatly (turns it to the right), the operation angle of the game ball launch handle 18 (a state in which the handle is returned to the right from the initial handle position when the handle is returned) A pulse signal having an amplitude value corresponding to the angle up to) is output from the handle operation signal output unit 406, and when the player turns the game ball launch handle 18 small (turns it to the right), the game ball launch A pulse signal having an amplitude value (a value smaller than the amplitude when the handlebar 18 is rotated to the right) according to the operation angle of the handlebar 18 (the angle from the handle initial position when the handlebar is returned to a state where the handlebar 18 is rotated to the right). Output from the handle operation signal output unit 406. In this way, the game ball can be driven into the game board 30 with the strength desired by the player. That is, the game ball launching device 38 launches a game ball with a launch output corresponding to the electrical signal (pulse signal) from the handle operation signal output unit 406.

  Further, the game ball launching device 38 is not of a type that strikes the game ball with a hammer driven by a motor or the like and launches it on the game board 30, but an electromagnetic game ball launching unit 228 that ejects the game ball in an electromagnetic manner. It has. Here, the configuration of the electromagnetic game ball launcher 228 and the principle of injection by the electromagnetic method will be described with reference to the drawings. FIG. 39 is a diagram showing a configuration of the electromagnetic game ball launching unit 228. As shown in FIG.

  As shown in FIG. 39, an electromagnetic game ball launcher 228 (electromagnetic ball launcher) includes a yoke 408 facing different magnetic poles with a slightly larger interval than the diameter of the game ball Ba, and the yoke 408. And a firing rail 61 as a launching path provided so as to penetrate between the magnetic poles of the yoke 408. The coil 410 of the electromagnetic game ball launcher 228 is supplied with an electric signal (pulsed current: pulse signal) from the handle operation signal output unit 406 described above. An example of the handle operation signal output unit 406 includes a handle operation signal output unit 406 (drive pulse generation circuit) that generates and outputs a pulse signal having an amplitude corresponding to the operation amount of the game ball launch handle 18. One end of the launch rail 61 is a launch ball standby position 412, and the game balls Ba stored in the upper plate 19 are supplied to the launch ball standby position 412 one after another.

  When the game ball Ba is fired, the coil 410 is energized until the game ball Ba that has been in the shot ball standby position 412 reaches the position 414 between the opposing magnetic poles, and the game ball Ba just reaches the position 414 between the magnetic poles. When the power is turned off, the power supply is stopped. The game ball Ba that has been in the firing ball standby position 412 is attracted by the magnetic force generated by the start of energization of the coil 410, and moves vigorously toward the inter-magnetic pole position 414. Is stopped, it is fired on the game board 30 through the launch rail 61 and the rail unit 50 as it is.

  For example, the drive pulse (pulse signal) in the normal firing mode is output at a maximum of 100 pulses per second as shown by the waveform HA in the figure, and in the high-speed firing mode, the pulse interval is as shown in the waveform HB. It becomes almost half, and a maximum of 200 pulses are output per second.

  By using such an electromagnetic game ball launching unit 228, the upper limit number of game balls Ba to be fired per unit time can be easily changed by adjusting the pulse period, and the game ball Ba can be changed by magnetic force. Since it is fired, the upper limit of the number of fires per unit time can be further increased.

  Further, since the distance between the magnetic poles is narrow on the side of the firing ball standby position 412 and is tapered near the tip of the magnetic pole so as to increase as the distance from the firing ball standby position 412 increases, the point where the magnetic flux density is highest is launched. It approaches the ball standby position 412. That is, the distance between the portion having the highest magnetic flux density between the magnetic poles and the firing ball standby position 412 is shortened, and the energization time to the coil 410 is shortened. As a result, the upper limit number of firings per unit time can be further increased.

  Note that the firing speed of the game ball Ba is adjusted by the amplitude of the pulse, that is, the value of the current flowing through the coil 410. Further, instead of immediately stopping the energization of the coil 410 after passing through the inter-magnetic pole position 414, an alternating magnetic field that gradually attenuates may be applied to demagnetize the flying sphere.

  That is, the game ball launching device 38 is located on the base end side of the rail unit 50 as a game ball launch path for introducing the game ball Ba into the game board 30 (see FIG. 4), and the game ball Ba to be launched. Is placed in the ball waiting position 412 (corresponding to the game ball arrangement means of the present invention), and the game ball Ba placed in the ball waiting position 412 is driven to the other end side of the rail unit 50 (to be driven into the game board 30). Coil 410 and yoke 408 (corresponding to the magnetic field generating means of the present invention) for generating a magnetic field, and the coil 410 and yoke according to the player's operation on the game ball launching handle 18 so that thrust is generated toward the side). Handle operation signal output unit 406 (corresponding to the magnetic field generation control means of the present invention) that controls the magnetic force generated by 408 and controls the magnetic field to be generated intermittently. That) and a.

Next, the principle of injection by the electromagnetic method will be described with reference to FIGS. FIG. 40A is a diagram for explaining the principle of the iron ball injection device by the solenoid 418, and FIG. 40B shows the trajectory of the iron ball injected by the injection device shown in FIG. FIG. 40C is a characteristic diagram showing the relationship between the initial speed v ₀ and the height h. FIG. 41A is a schematic circuit diagram showing a driving circuit of an iron ball injection device using a solenoid 418. FIG. 41B shows a case where the capacitor capacity is changed in the case of the driving circuit of FIG. It is a figure which shows the experimental result of the flying height of the iron ball at the time. FIG. 42A is a schematic circuit diagram showing a drive circuit of an example of an iron ball injection device using a solenoid 418, and FIG. 42B changes the voltage in the case of the drive circuit of FIG. It is a figure which shows the experimental result of the flying height of the iron ball at the time.

  As shown in FIG. 40 (a), when an iron ball (game ball Ba) is placed at the end of the solenoid 418 and a pulse current is passed through the solenoid 418, the iron ball (game ball Ba) is moved by the electromagnetic attraction force of the solenoid 418. Move to the center. In this case, if the magnitude of the pulse current and the pulse width are appropriate, the iron ball (game ball Ba) can be ejected from the solenoid 418 as indicated by the solid line arrow. Note that lines of magnetic force generated by applying a pulse current to the solenoid 418 are indicated by broken-line arrows.

For example, when an iron ball is thrown in any direction on the ground, its trajectory draws a parabola as shown in FIG. 40 (b), and the height h at the highest point is expressed by the following equation (1). The Where v ₀ is the initial velocity, θ is the radiation angle, and g is the gravitational acceleration.

h = v ₀ sin ² θ / 2g (1)
The range R is expressed by the following equation (2).

R = v ₀ ² sin 2θ / g (2)
In equation (1), when θ = 90 °, h = v ₀ ² / 2g is the highest, and the relationship between v ₀ and h is as shown in FIG. Further, the angle at which R is maximized from the equation (2) is θ = 45 °. If the mass of the iron ball is m and the acting force is F, the acceleration a of the iron ball is expressed by the following equation (3) and is proportional to the attractive force acting on the iron ball.

a = F / m (3)
The drive circuit of the injection device is a capacitor charge / discharge circuit as shown in FIG. 41A, and in particular, the discharge circuit has a small time constant so that a large current flows in a short time.

  As shown in FIG. 41A, the flying height of the iron ball has the highest point due to the capacitance of the capacitor C of the drive circuit. This is because a reverse force acts on the iron ball if the discharge time constant is too large. Further, since the acceleration of the iron ball increases when the power supply voltage is increased, the highest point moves to the smaller capacitor capacity (the smaller discharge time constant). In the solenoid 418, the discharge time constant is suitably 7 to 4.2 ms (milliseconds).

  In the injection device of pachinko, the injection speed is currently 100 pieces / min. Therefore, if the period is 0.6 seconds and the discharge time is 50 ms (10τd), 550 ms is the charge time, and charging is performed during this period. A time constant may be set. However, in this case, the peak value is large, and considering the fact that many units operate at the same time, the influence on the power supply is large, and because there is an influence of power supply fluctuation, it is better to charge at a constant current, and the range control is The current value can be controlled.

  Here, as shown in FIG. 42 (a), an example of a driving circuit of an iron ball injection device using a solenoid 418 used in a pachinko machine and a voltage-flight height relationship when the driving circuit is used will be described. To do.

  As shown in FIG. 42 (a), the drive circuit is supplied with a peak value of 28.3V at a power supply voltage (referred to as V in FIG. 42 (a)) 20V (volt) AC (alternating current), and the solenoid winding is φ1.0, 255t at 0.37Ω (ohms) is used, and a capacitor of 15000 μF (microfarad) for 30V is used.

The charging current (peak value) is I ₁ = 28.3 / 5 = 5.65 A (ampere). The charging current (average value) is I ₁ ′ = CE / t = 15000 × 10 ⁻⁶ × 28.3 / 0.45 = 0.94 A (120 pcs / min), and the charging current (average value) is I ₁ ′ = CE / t = 15000 × 10 ⁻⁶ × 28.3 / 0.55 = 0.78 A (100 / min). The charge time constant is T ₁ = 15000 × 10 ⁻⁶ × 5 = 75 ms, the discharge current (peak value) is I ₂ = 28.3 / 0.37 = 76.5 A (ampere), and the discharge time constant is Constant T ₂ = 15000 × 10 ⁻⁶ × 0.37 = 5.5 ms.

  As shown in FIG. 42B, when the voltage of the drive circuit is 19 V (volts), the flying height of the iron ball at that time is 70 cm, which can be said to be optimal for a pachinko machine. If the voltage of the drive circuit is 17.4V, the flying height of the iron ball at that time is 60 cm, which satisfies the minimum necessary flying height. If the voltage of the driving circuit is 21.4V, The flying height of the iron ball at that time is 80 cm, which satisfies the maximum necessary flying height.

  Returning to FIG. 38, a further configuration of the pachinko machine 10 of the present embodiment will be described. As shown in FIG. 38, the pachinko machine 10 according to the present embodiment has a forced change condition for forcibly changing the game ball launch output in the game ball launch device 38 without depending on the operation change of the game ball launch handle 18. Based on the condition establishment detection unit 440 that detects the establishment of the condition and the forced change condition establishment detection by the condition establishment detection unit 440, the game ball launch output in the game ball launch device 38 is changed to a predetermined launch output. And a control unit 450 that controls the game ball launching device 38 so as to forcibly change the operation without depending on the operation change of the handle 18.

  The control unit 450 includes a signal generator 452 that generates and outputs a predetermined electrical signal that uses the game ball launch output from the game ball launching device 38 as a predetermined launch output, and the forced change condition in the condition establishment detection unit 440. Based on the establishment detection, the signal generator 452 is preferentially selected over the handle operation signal output unit 406 so as to forcibly change the game ball launch output in the game ball launch device 38 to a predetermined launch output. The electric signal from the signal generator 452 is preferentially output to the electromagnetic game ball launching unit 228 of the game ball launching device 38.

  The condition establishment detection unit 440 includes an advantageous game state detection unit 442 that detects a game state advantageous to the player, and a start instruction detection unit 446 that detects the start instruction for the start instruction button 444 that receives a start instruction from the player. In addition, when the advantageous game state is detected by the advantageous game state detection unit 442 and the start instruction is detected by the start instruction detection unit 446, it is detected that the forced change condition is satisfied. The start instruction button 444 is disposed at a predetermined position of the pachinko machine 10 (for example, a predetermined position of the upper plate 19 (a predetermined position on the side or upper surface thereof)), and a start instruction from the player is input. ing. The condition establishment detection unit 440 corresponds to, for example, one of the functions of the CPU 501 of the main control device 261, and is realized by causing the CPU 501 to execute a predetermined program.

  As shown in FIG. 4, the game board 30 includes a specific entry portion 448 capable of entering a game ball at a predetermined place (in this embodiment, a place on the left end side of the game board 30). Yes. As the specific entry portion 448, various items such as a entrance and a winning entrance may be adopted. Ejected by the electromagnetic game ball launching section 228 with a launch output that is about to be driven into the game board 30, that is, with a strength enough to pass through the return ball prevention member 53 provided on the output port side of the rail unit 50. The game ball is easy to go to the specific ball entering portion 448 located on the left end side of the game board 30.

  Based on the forced change condition establishment detection by the condition establishment detection unit 440, the control unit 450 sends the game ball launch output in the game ball launch device 38 to the specific entrance unit 448 as a predetermined launch output. The electromagnetic game ball launching unit 228 is controlled so as to forcibly change the launch output that is easy to enter without depending on the operation change of the game ball launch handle 18. That is, based on the forced change condition establishment detection by the condition establishment detection unit 440, the control unit 450 sends the game ball launch output in the game ball launch device 38 to the specific ball entry unit 448 as the predetermined launch output. The signal generator 452 is preferentially selected over the handle operation signal output unit 406 so as to force the game ball to be easily changed without depending on the operation change of the game ball launch handle 18, The electric signal from the signal generator 452 is preferentially output to the electromagnetic game ball launcher 228.

  The control unit 450 receives the electrical signal from the handle operation signal output unit 406 and the electrical signal from the signal generator 452, mixes and outputs the mixed signal, and the condition satisfaction detection unit 440 forcibly. Based on the detection of change condition establishment, the electric signal from the handle operation signal output unit 406 is made non-input to the mixer circuit 454, and based on the detection of the forced change condition not established in the condition establishment detection unit 440, the signal from the signal generator 452 And a switching unit 456 for inputting an electric signal to the mixer circuit 454.

  The switching unit 456 may be any unit that can prevent the electrical signal from the handle operation signal output unit 406 from being input to the mixer circuit 454 when the condition change detection unit 440 detects the forced change condition being satisfied. There are various switches such as relays.

  The signal generator 452 generates and outputs a pulse signal having an amplitude corresponding to a launch output in which a game ball is likely to enter the specific ball entry portion 448 of the game board 30. Extremely speaking, it generates and outputs a pulse signal having an amplitude corresponding to the minimum emission output to the extent that the game board 30 is driven to the last minute. That is, when only the electrical signal from the signal generator 452 is input to the mixer circuit 454 without the electrical signal from the handle operation signal output unit 406 being input to the mixer circuit 454, the mixer circuit 454 generates the signal. The electromagnetic game ball launching unit emits a game ball with a launch output corresponding to the output from the device 452 and is driven to the left end side of the game board 30 at the last minute. You can hit a game ball with "Strike".

  Here, the forced change operation of the game ball launch output in the pachinko machine 10 will be described below.

  First, a description will be given of the game ball launch output in the normal case, that is, when the player can manipulate the game ball launch handle 18 to manipulate the launch of the game ball. That is, the normal case corresponds to a case where the forced change condition is not satisfied in the condition satisfaction detection unit 440.

  As shown in FIG. 38, when the game ball launching handle 18 is greatly rotated to the right by the player, a pulse signal having an amplitude level corresponding to the rotation angle (operation angle) is output from the handle operation signal output unit 406. When the game ball launching handle 18 is rotated to the right by a small angle, a pulse signal having an amplitude level corresponding to the rotation angle (operation angle) (a pulse signal having a smaller amplitude level than that of the previous rotation) Is output from the handle operation signal output unit 406.

  Since the condition change detection unit 440 does not satisfy the forced change condition, the switch 456a of the switching unit 456 is in the ON (connected) state, and the electrical signal (pulse signal) from the handle operation signal output unit 406 is the switching unit 456. Through the mixer circuit 454. At this time, an electric signal from the signal generator 452 is also input to the mixer circuit 454, and the mixer circuit 454 outputs an electric signal (pulse signal) from the handle operation signal output unit 406 and an electric signal (from the signal generator 452). Pulse signal) and output.

  The electrical signal (pulse signal) from the handle operation signal output unit 406 and the electrical signal (pulse signal) from the signal generator 452 are mixed in synchronization, The electric signal (pulse signal) and the electric signal (pulse signal) from the signal generator 452 are not mixed and shifted. That is, the pulse signals from the handle operation signal output unit 406 and the pulse signals from the signal generator 452 are overlapped, and the pulse width of the pulse signals is not increased by the pulse signal synthesis. . For example, based on the reference pulse signal, a pulse signal from the handle operation signal output unit 406 and a pulse signal from the signal generator 452 are generated at the same time.

  The pulse signal mixed by the mixer circuit 454 is output to the electromagnetic game ball launcher 228, and the electromagnetic game ball launcher 228 launches and outputs the game ball to the game board 30 with a launch output corresponding to the pulse signal. That is, the game ball is launched onto the game board 30 with a launch output in accordance with the operation of the game ball launch handle 18 by the player.

  In many cases, the player operates the game ball launch handle 18 (turns it to the right by a desired amount) so as to aim the game ball at a desired position on the game board 30 and hit the game board 30. In many cases, a game ball is shot into the left region when divided vertically. In general, the game ball launching handle 18 is operated so as to maintain the game ball being shot aiming at a target location slightly to the left of the center of the game board 30.

  Next, a case where the forcible change condition is satisfied, that is, a case where a predetermined firing output is forcibly replaced with the operation of the game ball launching handle 18 by the player will be described. That is, the case corresponds to the case where the condition change detection unit 440 detects that the forced change condition is satisfied.

  As shown in FIG. 38, the advantageous game state detection unit 442 of the condition establishment detection unit 440 determines that the first determination unit 404 is a big hit, thereby giving the player an advantageous game state (for example, a big win state). It detects that. In this advantageous game state, a predetermined game value is given to the player in accordance with the entry of the game ball into the specific entry portion 448 shown in FIG. 4, and the player is in the advantageous game state. Then, the player wishes to enter the game ball into the specific ball entry portion 448 at the left end of the game board 30. As the predetermined game value by entering the game ball into the specific ball entry unit 448, the jackpot state is made more advantageous, and the state where the number of game ball shots in the game ball launch device 38 is increased for a predetermined period is maintained. Alternatively, various game values such as a probability change state may be adopted.

  When the first symbol display device 42 displays that the first symbol is a big hit, the player can know the occurrence of an advantageous gaming state (a big hit state), and when the big hit state occurs, the player gives a start instruction The button 444 is operated to instruct the game ball launch output to be a predetermined output (a short shot output). The start instruction detection unit 446 detects an operation (start instruction) of the start instruction button 444 by the player. If the start instruction detection unit 446 detects a start instruction after the advantageous game state detection unit 442 detects an advantageous game state (for example, a big win state), the condition establishment detection unit 440 turns off the switch 456a of the switching unit 456 ( The electrical signal from the handle operation signal output unit 406 is not input to the mixer circuit 454 (one input terminal). At this time, the electric signal from the signal generator 452 is input to the mixer circuit 454 (the other input terminal), and the mixer circuit 454 outputs only the electric signal from the signal generator 452 and launches an electromagnetic game ball. The unit 228 launches a game ball with a launch output based only on the electrical signal from the signal generator 452.

  At this time, the electromagnetic game ball launching unit 228 launches the game ball with a launch output based only on the electrical signal from the signal generator 452, and thus the game ball is launched with a launch output such that the game ball 30 is driven to the last minute. The game ball is driven into the game board 30 at the last minute. The game ball that has been hit in this way is hit so that it can be easily put into the specific pitch portion 448 shown in FIG. At this time, whether or not the player operates (turns) the game ball launch handle 18, only the electric signal from the signal generator 452 is valid, and the game is based on only the electric signal from the signal generator 452. It can be seen that the launch power of the sphere has been determined.

  As described above, according to the pachinko machine 10 of the present embodiment, the game ball launching handle 18 that receives an operation related to the launching of the game ball by the player, and the game ball according to the player's operation on the game ball launching handle 18 is received. A game ball launching device 38 to be launched, a game board 30 having a game area into which a game ball launched by the game ball launching device 38 is driven, and a game ball launching device without changing the operation of the game ball launching handle 18 Based on the condition establishment detection unit 440 that detects the establishment of a forced change condition for forcibly changing the game ball launch output at 38 and the forced change condition establishment detection by the condition establishment detection unit 440, The game ball launching device 38 is controlled so as to forcibly change the launch output of the game ball in the device 38 to a predetermined launch output without depending on the operation change of the game ball launching handle 18. And the control unit 450, so that when the forced change condition is established, the game ball launching device 38 outputs the game ball launch output to a predetermined value without depending on the operation change of the game ball launch handle 18. It can be forcibly changed to the firing power. That is, when the forcible change condition is satisfied, the game ball launch output can be forcibly changed to a predetermined launch output without requiring any change in the operation of the game ball launch handle 18 by the player. The game ball can be driven quickly and appropriately into the game board 30 with a predetermined launch output. That is, it is possible to eliminate the delay time until the player changes to the predetermined launch output, which occurs when the player changes the operation of the game ball launch handle 18. As a result, it is possible to provide a gaming machine (pachinko machine) that can improve a decrease in the interest of the game due to the delay in handling the operation change of the game ball launching handle 18.

  In addition, the game ball launching handle 18 includes a handle operation signal output unit 406 that outputs an electrical signal corresponding to the amount of operation of the player with respect to the game ball launching handle 18 when the player receives an operation related to launching the game ball. The game ball launching device 38 launches a game ball with a launch output corresponding to the electrical signal from the handle operation signal output unit 406, and the control unit 450 outputs the game ball launch output from the game ball launching device 38. And a signal generator 452 that generates and outputs a predetermined electric signal with a predetermined launch output, and based on the forced change condition establishment detection by the condition establishment detection unit 440, the game ball launch output in the game ball launch device 38 The signal generator 452 is preferentially selected over the handle operation signal output unit 406 so as to forcibly change the output to a predetermined firing output, and the electric power from the signal generator 452 is selected. The game ball launching device 38 is output to the game ball launching device 38 preferentially, so that when the forced change condition is established, the game ball launching device 38 is not relied upon to change the operation of the game ball launching handle 18. The game ball launch output at can be forcibly changed to a predetermined launch output. That is, when the forced change condition is satisfied, the signal generator 452 is preferentially selected over the handle operation signal output unit 406 without requiring any change in the operation of the game ball launching handle 18 by the player. It is controlled to preferentially output the electric signal from the signal generator 452 to the game ball launching device 38, and the launch output of the game ball can be forcibly changed to a predetermined launch output, quickly and appropriately. The game ball can be driven into the game board with a predetermined launch output. That is, it is possible to eliminate the delay time until the player changes to the predetermined launch output, which occurs when the player changes the operation of the game ball launch handle 18. As a result, it is possible to provide a gaming machine that can improve a decrease in the interest of the game due to a delay in the operation change of the game ball launch handle 18.

  In addition, the condition establishment detection unit 440 detects an advantageous game state detection unit 442 that detects a game state advantageous to the player, and a start instruction detection unit 446 that detects the start instruction for the start instruction button 444 that receives a start instruction from the player. When the advantageous game state is detected by the advantageous game state detection unit 442 and the start instruction is detected by the start instruction detection unit 446, it is detected that the forcible change condition is satisfied. When the player enters an advantageous game state and receives a start instruction from the player, the game ball launch device 38 forces the game ball launch output to a predetermined launch output without changing the operation of the game ball launch handle 18. Can be changed. That is, when an advantageous gaming state is established and a start instruction is received from the player, the game ball launch output is output without requiring any change in the operation of the game ball launch handle 18 by the player. It is possible to forcibly change to a predetermined launch output, and it is possible to quickly and appropriately drive a game ball into the game board with a predetermined launch output. That is, it is possible to eliminate the delay time until the player changes to the predetermined launch output, which occurs when the player changes the operation of the game ball launch handle 18. As a result, it is possible to provide a gaming machine that can improve a decrease in the interest of the game due to a delay in the operation change of the game ball launch handle 18.

  In addition, the game board 30 includes a specific ball entry portion 448 capable of entering a game ball at a predetermined location, and the control unit 450 is based on the forced change condition establishment detection by the condition establishment detection unit 440. Forcing the game ball launch output in the game ball launch device 38 to a launch output in which the game ball is likely to enter the specific entrance portion 448 as a predetermined launch output without depending on the operation change of the game ball launch handle 18 The game ball launching device 38 is controlled so as to change automatically. Therefore, in the case where the forcible change condition is satisfied, the game ball is likely to be entered into the specific entrance portion 448 as the game ball launch output without requiring any change in the operation of the game ball launch handle 18 by the player. The launch output can be forcibly and automatically changed, and the game ball can be driven into the game board 30 with a launch output that allows the game ball to easily enter the specific entrance portion 448 quickly and appropriately. That is, it is possible to eliminate the delay time until the player changes to the predetermined launch output, which occurs when the player changes the operation of the game ball launch handle 18. As a result, it is possible to provide a gaming machine that can improve a decrease in the interest of the game due to a delay in the operation change of the game ball launch handle 18.

  Specifically, the control unit 450, based on the forced change condition establishment detection in the condition establishment detection unit 440, the game ball launch output in the game ball launch device 38 as a specific launch unit as a predetermined launch output The signal generator 452 is preferentially selected over the handle operation signal output unit 406 so as to forcibly change the output of the game ball to be easily entered at 448 without depending on the operation change of the game ball launch handle 18. Since the electric signal from the signal generator 452 is preferentially output to the game ball launching device 38, the operation change of the game ball launching handle 18 by the player is not required when the forced change condition is satisfied. Without changing the game ball launch output, the game ball can be forcibly and automatically changed to a launch output at which the game ball is likely to enter the specific ball entry portion 448. Entered 448 It can be implanted game balls on the game board 30 in an easy firing output. That is, it is possible to eliminate the delay time until the player changes to the predetermined launch output, which occurs when the player changes the operation of the game ball launch handle 18. As a result, it is possible to provide a gaming machine that can improve a decrease in the interest of the game due to a delay in the operation change of the game ball launch handle 18.

  The control unit 450 receives an electrical signal from the handle operation signal output unit 406 and an electrical signal from the signal generator 452, and mixes and outputs them, and a condition establishment detection unit 440 An electric signal from the handle operation signal output unit 406 is not input to the mixer circuit 454 based on the detection of the forced change condition being established, and a handle operation signal is output based on the detection of the forced change condition not being satisfied by the condition establishment detection unit 440. And a switching unit 456 for inputting the electric signal from the unit 406 to the mixer circuit 454. Therefore, when the forcible change condition is satisfied, the electric signal from the handle operation signal output unit 406 is not transmitted to the mixer circuit 454. Only the electric signal from the handle operation signal output unit 406 can be input to the mixer circuit 454, and the mixer circuit 54, that is, only the electric signal from the signal generator 452 can be output to the game ball launcher 38, and the game ball launcher 18 can be output without changing the operation of the game ball launcher handle 18. The game ball launch output at 38 can be forcibly and automatically changed to a predetermined launch output based solely on the electrical signal from the signal generator 452. In short, when the forcible change condition is satisfied, the game ball can be launched with the launch output based only on the electric signal from the signal generator 452, and therefore the amount of operation of the game ball launch handle 18 by the player is not reflected. The game ball can be launched with a constant launch output based only on the electrical signal from the signal generator 452.

  The game ball launching device 38 is located on the base end side of the rail unit 50 for introducing the game ball into the game board 30, and a launch ball standby position 412 where the game ball to be launched is placed, and the launch ball A coil 410 and a yoke 408 that generate a magnetic field so that a game ball placed at the standby position 412 generates a thrust toward the other end of the rail unit 50, and a coil according to a player's operation on the game ball launching handle 18. 410, a handle operation signal output unit 406 for controlling the magnetic force generated by the yoke 408 and controlling the magnetic field to be generated intermittently. Further, the handle operation signal output unit 406 is a condition establishment detection unit 440. When the forcible change condition is detected, the magnetic force generated by the coil 410 and the yoke 408 is changed according to the predetermined output from the control unit 450. Control and control to generate the magnetic field intermittently. Therefore, even when an electromagnetic game ball launching device (electromagnetic injection device) that launches a game ball with the generated magnetic field is adopted, It is possible to provide a gaming machine that can improve a decrease in the interest of the game due to a delay in handling the operation change of the firing handle 18. In addition, the electromagnetic game ball launcher 38 (electromagnetic injection device) described above does not require a hammer, motor, or the like that strikes the game ball, so that it can be made more compact than a launch game ball launcher. , Space merit arises. Moreover, since the magnetic field is generated based on the electric signal (pulse signal), the launch output of the game ball can be adjusted only by controlling only the electric signal (pulse signal) that generates the magnetic field. Mechanical adjustment elements (elements for adjusting the mechanical configuration such as a hammer or a motor that strikes the game ball) can be eliminated, and the launch of the game ball can be adjusted accurately.

  The present invention is not limited to the above embodiment, and can be modified as follows.

  (1) In the embodiment described above, as shown in FIG. 39, a game ball is launched onto the game board 30 using the electromagnetic game ball launcher 38 (electromagnetic game ball launcher 228). In addition to the electromagnetic game ball launching device 38, various game ball launching devices such as a launching type game ball launching device may be adopted. For example, a launch-type game ball launching device includes a hitting ball spear and launches a game ball with the rotation of the hitting ball centering around a shaft portion.

  (2) In the embodiment described above, the condition establishment detection unit 440 starts when the advantageous game state (big hit state) is detected by the advantageous game state detection unit 442 and when the player presses the start instruction button 444. The fact that the forcible change condition has been detected is detected because the instruction is detected by the start instruction detection unit 446, but only by the advantageous gaming state (big hit state) being detected by the advantageous gaming state detection unit 442, You may make it detect as establishment of forced change conditions. In addition, the condition establishment detection means is a detection member such as a winning device, a winning component, a winning device, a winning component, or the like, which is disposed at a predetermined location on the game board 30 to detect the entry or passage of a game ball, If there is detection by the detection member, the forced change condition may be satisfied.

  (3) In the above-described embodiment, the control unit 450 switches only to the electric signal of the signal generator 452 when the forced change condition is satisfied, but when the forced change condition is satisfied, The electrical signal from the handle operation signal output unit 406 is attenuated by a predetermined amount and input to the mixer circuit 454 (mixing output means), and the attenuated electrical signal and the electrical signal of the signal generator 452 are mixed into the mixer circuit 454 (mixed output). And the like may be mixed and output. The “predetermined amount of attenuation” includes attenuating the electrical signal from the handle operation signal output unit 406 to such an extent that the electrical signal from the signal generator 452 becomes dominant. In this case, when the forcible change condition is satisfied, the electric signal from the handle operation signal output unit 406 is attenuated to such an extent that the electric signal from the signal generator 452 becomes dominant, and the mixer circuit 454 is obtained. Therefore, the electric signal from the signal generator 452 that becomes dominant when compared with the electric signal output from the mixer circuit 454, that is, the electric signal from the handle operation signal output unit 406, is used as a game ball. The output of the game ball in the game ball launch device 38 can be output to the launch device 38 without changing the operation of the game ball launch handle 18. Can be forcibly and automatically changed to a predetermined firing power. In addition, since the electrical signal from the handle operation signal output unit 406 is attenuated and input to the mixer circuit 454, the game ball launch output 18 by the player can be finely adjusted.

  (4) In the above-described embodiment, when the forcible change condition is established, the minimum output of the game ball is output (to the extent that it finally reaches the game board 30, that is, from the return ball prevention member 53 of the game board 30). It is set to the extent that the game board 30 is driven out into the game area. In other words, the electric signal (pulse signal) of the signal generator 452 is an electric signal having an amplitude such that the minimum emission output is obtained, but the electric signal enters the specific ball entry portion 448 provided at an arbitrary position of the game board 30. You may make it the output of the grade which is easy to ball. For example, a specific entry portion 448 is provided on the right end side of the game board 30 and the electric signal of the signal generator 452 is changed so that it is easy to enter the specific entry portion 448 when a forced change condition is satisfied. In addition, the switch 456a of the switching unit 456 may be turned off (disconnected) so that the switching unit 456 does not input the electrical signal (pulse signal) from the handle operation signal output unit 406 to the mixer circuit 454. By so doing, so-called “right-handed” can be forcibly and automatically performed when the forcible change condition is satisfied.

  (5) In the above-described embodiments, the present invention may be implemented in various (for example, first type, third type, etc.) gaming machines, or in a different type of pachinko machine from the above embodiments. Also good. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Moreover, after a jackpot symbol is displayed, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a ball is won in a predetermined area. Moreover, you may implement as a pachinko machine which will be in a special game state when a ball enters a predetermined winning opening. Further, in addition to pachinko machines, various game machines such as an arrangement ball type pachinko machine, a sparrow ball, a game machine in which a so-called pachinko machine and a slot machine are integrated may be used.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a variable display means for displaying a fixed symbol after a variable symbol row consisting of a plurality of symbols is provided, and a handle for launching a ball is provided. What is not provided. In this case, after inserting a predetermined amount of game balls based on a predetermined operation (button operation), for example, the variation of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or the predetermined amount With the passage of time, the fluctuation of the symbol is stopped, and a jackpot state that is advantageous to the player is generated on the condition that the fixed symbol at the time of stoppage is a so-called jackpot symbol. A lot of balls are paid out.

  As described above, the present invention is suitable for gaming machines such as pachinko machines and slot machines.
