Description

  The present invention relates to gaming machines such as pachinko machines and slot machines.

  Conventionally, there is a pachinko machine, for example, as a representative example of a gaming machine. This pachinko machine includes, for example, a housing having a game board inside, and a front door having a transparent member that covers a predetermined location on the front side of the game board, and the front door is open to the housing. It can be opened and closed freely. In other words, the front door can be freely opened and closed so that one side of the front door is rotated about an axis and only the other side is opened and closed (see, for example, Patent Document 1).

JP-A-9-75530 (page 12, FIG. 9)

However, the conventional example having such a configuration has the following problems.
That is, as a conventional pachinko machine, for example, when the pachinko machine is viewed from the front so that the front door as an example of an opening / closing body can be opened and detached with respect to a housing as an example of a main body Some pachinko machines have a plurality of (for example, two) pulling hinges disposed at one end side (for example, the left end side) at intervals along the left end side. That is, the pulling hinge is composed of a hinge piece having a core bar (insertion core) and a hinge piece having a tube into which the core bar is inserted, and one hinge piece is located above the left end side of the housing. The other hinge piece corresponding to the hinge piece is attached to the upper part on the left end side of the front door, and similarly, one hinge piece is attached to the lower part on the left end side of the housing. The other hinge piece corresponding to the piece is attached to a lower portion on the left end side of the front door. Thus, in a pachinko machine having a plurality of (for example, two) pulling hinges, there is a problem that the front door cannot be easily attached to the housing. In other words, the front door must be attached to the housing so that the respective hinges are simultaneously fitted at the upper and lower positions on the left end side of the pachinko machine, and the upper and lower positions on the left end side of the pachinko machine. This is because even if the hinge is fitted, the pulling hinge does not fit in the lower part, or the reverse state is reached, which is not easy.

  In addition, the workability of attaching the front door to the housing can be improved a little by making the lengths of the upper and lower insert hinges different from each other. The core metal of the other hinge piece needs to be inserted, and the size of the core metal and the pipe is substantially the same. Therefore, it is difficult to say that it can be easily attached. In addition, it may be possible to make it easier to attach the front door to the housing by increasing the play when the cored bar is inserted into the tube. Since the door is not in a relaxed state with respect to the housing, the core metal and the tube must be made approximately the same size.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the gaming machine which can attach an opening / closing body to a main body easily.

  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as a “pachinko machine”) will be described in detail with reference to the drawings. FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 is a perspective view showing a state in which the inner frame 12 and the front frame set 14 are opened with respect to the outer frame 11. However, FIG. 2 shows a state in which the lower plate unit 13 is removed from the inner frame 12 for convenience.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 that is supported on one side of the outer frame 11 so as to be opened and closed. ing. Below, the structure of the outer frame 11 and the inner frame 12 is demonstrated in detail separately.

  The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm). The outer frame 11 may be made of a light metal such as resin or aluminum.

  The opening / closing axis of the inner frame 12 is set so as to extend vertically on the opposite side (left side of the pachinko machine 10 in FIG. 1) from the position where the handle (game ball launching handle 18 described later) is installed as viewed from the front of the pachinko machine 10. The inner frame 12 can be sufficiently opened to the front side with the opening / closing axis as an axis. For example, assuming that the opening / closing axis of the inner frame 12 is in the vertical direction on the handle installation location side (the right side of the pachinko machine 10 in FIG. 1), the head of the game ball launching handle 18 is adjacent when the inner frame 12 is opened. Will interfere with the pachinko machine or card unit (ball lending unit), and the inner frame 12 cannot be fully opened. The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile-butadiene-styrene) resin. By doing so, it is highly viscous and resistant to impact, and can be manufactured at low cost.

  The configuration of the inner frame 12 will be described in detail with reference to FIG. FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 3, the configuration in the game area on the surface of the game board 30 is shown as blank for convenience).

  The inner frame 12 is roughly divided into a lower tray unit 13 attached to the lowermost portion thereof, and an opening / closing axis on the left and right sides of the inner frame 12 in the upper range of the lower tray unit 13 as an axis. A front frame set 14 that is freely attached, a resin base 20 to be described later, and a game board 30 that is attached to the rear side of the resin base 20 are provided. Each of these configurations will be described in detail below.

  The lower plate unit 13 is fixed to the inner frame 12 with a fastener such as a screw. On the front side of the lower tray unit 13, a lower tray 15, a ball release lever 17, a game ball launching handle 18, an ashtray 22, and a sound output port 24 are provided. The lower tray 15 as a ball receiving tray is provided at the substantially central portion of the lower tray unit 13, and the game balls discharged from the discharge port 16 can be stored in the lower tray 15. The ball removal lever 17 is for removing a game ball in the lower plate 15. By moving the ball removal lever 17 to the left in FIG. 1, a predetermined position on the bottom surface of the lower plate 15 is opened, The game balls stored in the dish 15 can be pulled out downward through the opening on the bottom surface of the lower dish 15. The game ball launching handle 18 is disposed so as to protrude to the front side on the right side of the lower plate 15. In accordance with the operation of the game ball launching handle 18 by the player, the game ball launching device 38 drives the game ball toward a game board 30 described later. The game ball launching device 38 includes a game ball launching handle 18, a set handle 228, which will be described later, a launching motor 229 (see FIG. 6), and the like. The game ball launching device 38 described above corresponds to the game ball launching means in the present invention. The sound output port 24 is an output port for outputting sound from a speaker provided in the lower plate unit 13 or on the back surface. The ashtray 22 is provided on the left side of the lower plate 15. The right side of the ashtray 22 is cantilevered by the lower plate 15 so that the ashtray 22 rotates about the axis in the left-right direction (horizontal direction).

  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 behind 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 resistant to 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 the upper decorative frame 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 to be extended below the pachinko machine 10 so as not to interfere with at least the game ball launching handle 18. The dimension to the lower end of the front frame set 14 (H1 in FIG. 1) 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 part 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 out game balls that are lent out in this embodiment, 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, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The vertical length of the game board 30 is 476 mm, and the horizontal length is 452 mm (same size as before).

  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 arrange | positions at each through-hole formed by processing, respectively, and is attached with the wood screw etc. from the game board 30 front side. A game ball enters the above-described general winning port 31, variable winning device 32, and first start 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, and game balls that have not entered the various winning devices etc. are guided through the out port 36 to a ball discharge path (not shown). It has become. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display unit 35 has a first symbol display device 42 for variably displaying a first symbol (for example, a special symbol) as identification information with a winning at the first starting port 33 as a trigger, and a second starting port 34. And a second symbol display device 41 for variably displaying a second symbol (for example, a normal symbol).

  The second symbol display device 41 has a second symbol display unit 43 and a holding lamp 44, and each time a game ball passes through the second starting port 34, for example, a display symbol (ordinary symbol) by the display unit 43 is displayed. The first start port 33 is configured to be in an activated state (opened) for a predetermined time when the fluctuation display stops at a predetermined symbol. 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 lighted and displayed by the hold lamp 44. The display unit 43 may be configured to be variably displayed by a part of the first symbol display device 42 (liquid crystal display device) in addition to the configuration to be variably displayed by switching lighting of a plurality of lamps. . Similarly, the hold lamp 44 may be configured to be variably displayed on a part of the first symbol display device 42. The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The first symbol display device 42 is configured as a liquid crystal display device, and the display content is controlled by a display control device 45 described later. The first symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are variably displayed on the first symbol display device 42 so as to be scrolled for each symbol row. In the present embodiment, the first symbol display device 42 (liquid crystal display device) includes a large liquid crystal display of 8 inches. The variable display device unit 35 is provided with a center frame 47 so as to surround the first symbol display device 42. The first symbol display device 42 described above corresponds to the identification information variation display means in the present invention, and the display control device 45 described above 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 the event of a big win. ing. More specifically, when a game ball wins at the first start opening 33, the symbols are displayed in a variable manner on the first symbol display device 42, and the confirmed symbol after the stop is a combination of specific symbols set in advance. A special gaming state occurs as a necessary 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 so as to be variably displayed on a part of the first symbol display device 42.

  Further, the game board 30 is 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 launched 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 molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are 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 1/4 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 this 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 toward the left) where the rails 51 and 52 are parallel to each other with 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 of the inner rail 51 (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). Therefore, 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 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 a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30. In this embodiment, in order to 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. The adhesion to the game board 30 with respect to the left side can be improved, and the ball flying of the 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. The lower right corner and the lower left corner of the game board 30 are spaces for sticking stickers (S1, 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 seal 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 portion (inner and outer rails) of the rail unit 50. In particular, in this embodiment, the game area partitioned on the board surface of the game board 30 is far more than conventional. It is greatly configured. 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 the guide rail region which is a parallel part of the inner and outer rails 51 and 52. As an area. Therefore, when it is referred to as a game area, the guide rail portion is not included, and 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. Further, 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 more preferably 460 mm or more. Of course, it is good also as 470 mm or more, 480 mm or more, and 490 mm or more. 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 much larger than the conventional area ratio. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the past, so it can be said that the game area is considerably expanded on the premise that the game board 30 is shared. It should be noted that the external shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 must be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more.

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

  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 start 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 a game ball. 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. 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 (launch angle). Accordingly, the 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 path 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 compared to the conventional case, but under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 61 is made somewhat larger than that of the existing one (that is, the launch rail 61 is raised) to further launch. The length of the rail 61 is made longer than the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launcher 38 can be guided to the guide rail in a more stable state. Particularly in this case, the launch rail 61 is formed so as to extend from the launch position of the game ball launcher 38 to a position beyond the center position (out port 36) of the game area.

  Further, there is a gap of a predetermined interval between the firing rail 61 and the rail unit 50 (guidance rail), and a foul ball passage 63 is formed below the gap. Therefore, if the game ball launched from the game ball launching device 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 drop downward when reaching the lower end of the outer rail 52. However, some foul spheres fall inside the guide rail. 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, but in the vicinity of the base end portion of the launch rail 61, its right side and 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. Further, the game ball launching device 38 is provided with a ball striking ball, and a game ball is launched with the rotation of the ball striking center around the shaft portion. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to light metal such as aluminum and reducing the size of the shaft, the head portion of the hitting ball (on the side opposite to the shaft) is secured to ensure sufficient firing force. A weight is provided at the end. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, it is possible to easily pick or hit the hitting ball, and it is easy to adjust the hitting strength of the hitting tip.

  In addition, the code | symbol 67 in FIG. 3 is the discharge port connected to the upper plate 19, and a game ball is discharged to the upper plate 19 through this discharge port 67. FIG. 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. In a state where 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, so that the game ball does not fall out from the discharge port 67. 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 this 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 inside 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 attached from the small window 71.

  As shown in FIG. 3, support metal fittings 81 and 82 are attached to the left end portion of the inner frame 12 as a support mechanism that supports the front frame set 14 so that it can be opened in one side. The structure of the support fittings 81 and 82 will be described in detail later.

  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 visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear. In the present embodiment, the distance between the upper end of the window portion 101 (the uppermost portion of the outer rail 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 with an upper frame width of about 85 mm to 95 mm. As a result, the upper area of the game area can be easily secured, and the large variable display device unit 35 can also be arranged relatively upward. The distance between the upper end of the front frame set 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

  Further, the shortest distance between the left end of the window portion 101 and the left end of the front frame set 14 when viewed from the front of the pachinko machine 10 (the left-right width of the so-called left side frame portion: shown on the right side in FIG. 5), The frame width on the opening / closing axis side is set to be relatively large in order to increase the strength and support strength of the front frame set 14 itself. In this case, as is apparent from a 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 around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks when the jackpot is informed that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 having a built-in light emitting means such as an LED. In addition, on the left and right sides of the central illumination unit 103, there are provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs. Further, a small window 107 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.

  In addition, a ball lending operation unit 120 is disposed below the window unit 101, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. 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 not protruded more than necessary to the front side (the front side 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 (so-called elephant nose) of the ball lending device 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 respectively attached to the back side of the front frame set 14 and on the top, bottom, left, and right sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. 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 of FIG. 5 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof, and this 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 reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and a part of the reinforcing plates 131 to 134 is folded back to form a glass holding groove. The glass holding grooves are formed in two rows in the front and rear, and a pair of front and rear glasses 137 having a rectangular shape are held in each glass holding groove. Thereby, the two glass 137 is attached to the front and back at a predetermined interval.

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

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

  Further, a portion where the guide rail protrudes from the side edge portion of the glass 137 is provided at the right end portion of the rail cover 140 (that is, the portion which becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front frame set 14). A covering portion 141 for covering is provided. As a result, it is possible to prevent the occurrence of problems such as game balls spilling out of the guide rail (jumping out) or being 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 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 substantially 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 intruded through a gap between the front frame set 14 and the inner frame 12 to perform an illegal act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. In addition, it is good also as a structure which forms the protrusion 142 in a wider range, for example along the whole region of the inner edge of the rail cover 140. According to this structure, it becomes difficult to infiltrate a wire etc. in a wider range, a wire etc. It is possible to more reliably prevent fraud performed using

  Further, on 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), mounting plates 151 and 152 that are detachable from the support fittings 81 and 82 (see FIG. 3) of the inner frame 12 are provided. Is attached. Therefore, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the mounting plates 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 on the inner frame 12 side (see FIG. 3) It comes to be attached to. The structure and the like of the mounting plates 151 and 152 will be described in detail later.

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

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

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

  Actually, the units 201 to 203 are arranged and attached as shown in the schematic diagram of FIG. In FIG. 8, the first control board unit 201 having a substantially L shape is arranged in the approximate center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Further, the back pack unit 203 is arranged in a region partially overlapping the first control board unit 201.

  Specifically, the first control board unit 201 is provided with a support shaft part M1 at the left end portion when viewed from the back of the pachinko machine 10, and the first control board unit 201 is centered on the axis A by the support shaft part M1. It can be opened and closed. Further, the first control board unit 201 is provided with a fastening portion M2 made of a ny latch or the like at the right end portion thereof (that is, the side opposite to the support shaft portion, more specifically, the open end side), and the locking claw portion M3 at the upper end portion. The first control board unit 201 is fixed and 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 the 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 on the left end portion thereof (that is, on the side opposite to the support shaft portion, more specifically, on the open end side), and at the upper end portion and the lower end portion, respectively. The backpack unit 203 is fixedly held to the main body of the pachinko machine by the fastening part M7 and the locking parts M8, M9.

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

  On the other hand, FIG. 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 does not fall off by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated and can be switched 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 metal fittings formed by bending metal pieces, and are configured not to protrude outward from the inner frame when the game board 30 is fixed.

(Similar) is an area for storing stack pointers, values of registers, I / O, and the like. Writing to the backup area 503a is executed when the power is turned off by NMI interrupt processing (see FIG. 33). Conversely, returning of each value written to the backup area 503a includes turning on the power (including turning on the power due to power failure cancellation). The same applies to the following power recovery process.

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

Lines 530 and 531 are provided. The output of the main controller 261 is connected to the input of the input port 527, and the CPU 521, ROM 522, work RAM 523, and image controller 526 are connected to the output of the input port 527 and one output port is connected via the bus line 530. 528 is connected. The output of the output port 528 is connected to the second symbol display device 41 (display unit 43) and the sound lamp control device 262. Further, an output port 529 is connected to the image controller 526 via a bus line 531, and a first symbol display device 42 which is a liquid crystal display device is connected to an output of the output port 529.

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

  The video RAM 524 is a memory for storing display data displayed on the first symbol display device 42, and the display contents of the first symbol display device 42 are changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as symbols displayed on the first symbol display device 42. The image controller 526 adjusts the timings of the CPU 521, the video RAM 524, and the output port 529 to intervene in reading and writing data, and also reads display data stored in the video RAM 524 from the character ROM 525 at a predetermined timing. It is displayed on the symbol display device 42.

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

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal 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 DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal 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).

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

  The RAM erase switch circuit 543 is a circuit for taking in the switch signal of the RAM erase switch 323 and clearing backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal 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, in the first symbol display device (liquid crystal display device) 42, as shown in FIG. 24, three symbol rows L, M, and R of left, middle, and right are set. For each R, three symbols of the upper symbol, the middle symbol, and the lower symbol (first symbol: for example, 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 the present embodiment, the CPU 501 in the main control device 261 performs lottery (big hit lottery) of the first symbol display device 42, setting of symbol display, and the like using various counter information in the game. Specifically, 25, the jackpot random number counter C1 used for the jackpot lottery of the first symbol display device 42, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 42, and the first Reach random number counter C3 used for reach lottery when the symbol display device 42 fluctuates and changes, random number initial value counter CINI used for initial value setting of the jackpot random number counter C1, and variation pattern selection of the first symbol display device 42 Fluctuation type counters CS1 and CS2 to be used, and left, middle and right outliers used for setting left out, middle and right outliers Counter CL, CM, has been with the use of the CR. 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 certain state.

  The jackpot symbol counter C2 determines a symbol when the fluctuation of the first symbol display device 42 is stopped in the case of a jackpot. In the present embodiment, the first symbol display device 42 has five effective lines. Since ten specific symbols (main symbols) 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 is also reached. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. Note that the reach drawing may be set individually according to the state of the lottery probability of the first symbol display device 42, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the 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, and the second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol.

  The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of CS1 and CS2 are acquired when the first symbol display device 42 determines the variation pattern at the start of variation of the first symbol.

  The left, middle, and right out symbol counters CL, CM, and CR indicate that the first symbol in the left column, the first symbol in the middle column, and the first symbol in the right column when the jackpot lottery of the first symbol display device 42 is lost. This is for determining the stop symbol (disconnected symbol). In each column, any one of the 20 first symbols including the main symbol and the sub symbol is displayed, so 20 (0 to 19) each. Counter values are provided. 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 processing 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 out 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 display device 41. 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 the present embodiment, 676, 49 and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  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. If it is determined that the game ball has won the first start opening 33, in the subsequent step S702, is the number N of active suspension balls of the first symbol display device 42 less than the upper limit value (4 in the present embodiment)? Determine whether or not. 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 controller 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, in the NMI interrupt processing of the payout control device 311, the power-off notification command in step S 804 is not transmitted).

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 turned 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, when the first symbol display device 42 displays the variation of the first symbol, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45. 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 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 permitted on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, display control of the second symbol by the second symbol display device 41 is executed. 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 device 41 of the second symbol display device 41 receives the second symbol. Symbol variation display is performed. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and the first starting port 33 is opened for a predetermined time when the winning state of the second symbol is reached. 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. The jackpot includes a special game displayed on the first symbol display device 42 and a predetermined time after the special game is ended. In a succeeding step S402, it is determined whether or not the first symbol display device 42 is displaying the variation of the first symbol. Then, if it is not a big hit and further is not displaying the variation of the first symbol, the process proceeds to step S403, and it is determined whether or not the number N of actuated balls of the first symbol display device 42 is greater than zero. At this time, if the jackpot is being hit or if the number N of operation-reserved 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 change start process is executed. 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. “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 is generated, the process proceeds to step S508, and the left, middle, and right outreach 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 S611, a fluctuation pattern at the time of complete deviation is determined, and the fluctuation pattern is set as a 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, for example, a checksum value at a work area address in the RAM 513. It should be noted that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  If the RAM erase switch 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, the interrupt permission is set.

  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. 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, and the ball motor processing is executed by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball game 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 winning ball control process shown in FIG. 36, in step S1101, the payout motor 358a is driven to execute payout of the winning ball. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, where the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal, the process proceeds to step S1104, and whether or not the game ball is normally counted is determined based on the detection result of the payout count switch. If the game ball count is not normal, the process 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.

A member 164 is provided.

  As shown in FIGS. 46 to 48, the guide member 164 is a notch portion 165 that guides the distal end portion 480 b of the variable link pin 480 to the insertion hole 162 through a notch passage connected to the insertion hole 162. . As shown in FIG. 48, the shape of the notch 165, that is, the shape of the notch passage is an arc. Specifically, a straight line segment connecting the center of the slide link pin 470 to the center of the insertion hole 162 is defined with the center of the slide link pin 470 as the rotation center axis and the insertion hole 162 as the rotation end. An arc shape is generated by rotating the insertion hole 162 closer to the insertion hole 162. The width of the notch 165, that is, the width of the notch passage is larger than the diameter of the distal end portion 480b of the variable link pin 480 and smaller than the diameter of the base end portion 480a. The size of the insertion hole 162 is such that at least the base end portion 480a of the variable link pin 480 can be inserted.

  The guide member 164 brings the mounting plate 151 close to the variable link pin 480 with the slide link pin 470 as the axis while the outer fitting notch 160 is fitted on the outer periphery of the slide link pin 470. By rotating in the direction, the distal end portion 480b of the variable link pin 480 is guided to the insertion hole 162.

  Since the mounting plate 152 has substantially the same configuration as that of the mounting plate 151 described above, the following description will focus on components that are different from the mounting plate 151 in the mounting plate 152.

  As shown in FIG. 46 (d), the mounting plate 152 has a “U” shape on the lower side, for example, when viewed from the side, and includes a two-stage mounting plate 152 a. The lower mounting plate 151a of the two stages is provided with an external fitting notch 160 that is externally fitted to the outer periphery of the slide link pin 470 disposed on the attachment / detachment connection plate 450 of the support fitting 82. It has been. An insertion hole 162 into which the base end portion 480a of the variable link pin 480 is inserted into the upper mounting plate 152a of the two steps, and a guide for guiding the distal end portion 480a of the variable link pin 480 into the insertion hole 162. A member 164 is provided.

It corresponds to a transition part.

  Here, the operation of attaching the front frame set 14 to the inner frame 12 will be described with reference to FIG. As shown by the broken line arrow in FIG. 47 (a), the notch 160 for external fitting of the mounting plate 151 of the front frame set 14 is externally fitted to the slide link pin 470 of the detachable connecting plate 450, The front frame set 14 is positioned at an attachment start position that is laid on the inner frame 12. In other words, the outer fitting notch 160 is fitted so as to be in horizontal contact with the outer peripheral portion of the slide link pin 470, so that the front frame set 14 is positioned at the attachment start position so as to be horizontal to the inner frame 12. Similarly to this, the notch 160 for external fitting of the mounting plate 151 of the front frame set 14 is externally fitted to the slide link pin 470 of the detachable connecting plate 450.

  The mounting plate 151 of the front frame set 14 and the notch 160 for external fitting of the mounting plate 152 may be simultaneously externally fitted to the slide link pins 470 of the respective support fittings 81 and 82. The external fitting cutout portion 160 of the mounting plate 151 is externally fitted to the slide link pin 470 before the mounting plate 152, and then the external fitting cutout portion 160 of the placement plate 152 is inserted into the slide link pin. It may be fitted on 470 or vice versa.

  47 (b) and FIG. 48 (b), the front frame set 14 is slid while maintaining the state in which the outer fitting notch 160 is brought into contact with the slide link pin 470, as indicated by broken line arrows. Using the link pin 470 as a rotation axis, the insertion hole 162 is rotated so as to approach the variable link pin 480. At this time, the distal end portion 480 b of the variable link pin 480 is guided to the insertion hole 162 through the notch portion 165.

  47 (c), when the variable link pin 480 is positioned in the insertion hole 162, the operator loosens the force of gripping the front frame set 14, and the weight of the front frame set 14 causes the weight of FIG. The front frame set 14 is lowered in the depth direction perpendicular to the paper surface, and the base end portion 480 a of the variable link pin 480 is inserted and fitted into the insertion hole 162. When the front frame set 14 is lowered in a state where the axis of the variable link pin 480 and the center of the insertion hole 162 are not completely coincident with each other, the front frame set 14 is smoothly guided by the taper portion 480c, and the variable link is inserted into the insertion hole 162. The base end portion 480a of the working pin 480 is inserted and fitted.

  As described above, according to the pachinko machine 10 of this embodiment, one end side of the front frame set 14 is rotated about the rotation axis J, and the other end side of the front frame set 14 is opened and closed with respect to the inner frame 12. The single-opening mechanism unit 400 further includes a plurality of attachment / detachment mechanism units 500 in the direction of the rotation axis J that allow the front frame set 14 to be attached to and detached from the inner frame 12. 500 includes support brackets 81 and 82 provided on the inner frame 12, and mounting plates 151 and 152 which are detachably attached to the support brackets 81 and 82 and provided on the front frame set 14. Provided is a variable link pin 480 that has a distal end portion 480b having a smaller diameter than a base end portion 480a and is disposed such that its longitudinal direction is in the direction of the rotation axis J. The mounting plates 151 and 152 are variable. Link pin 4 Since the insertion hole 162 into which the base end portion 480a of 0 is inserted and the guide member 164 for guiding the distal end portion 480b of the variable link pin 480 to the insertion hole 162 are provided, the distal end portion of the variable link pin 480 Since 480b is guided toward the insertion hole 162 by the guide member 164, the distal end portion 480b of the variable link pin 480 can be easily guided to the insertion hole 162. That is, the front frame set 14 can be easily attached to the inner frame 12. Further, the base end portion 480a of the variable link pin 480 is inserted into the insertion hole 162 by inserting the variable link pin 480 into the insertion hole 162 with the distal end portion 480b of the variable link pin 480 positioned in the insertion hole 162. So that the front frame set 14 is not detached from the inner frame 12 when the front frame set 14 is opened or closed. Can be opened and closed.

  Further, since the notch 165 guides the tip end portion 480b of the variable link pin 480 to the insertion hole 162 through the notch passage, the tip end portion 480b of the variable link pin 480 is moved through the notch passage. As a result, the distal end portion 480b of the variable link pin 480 can be directed directly to the insertion hole 162, and the distal end portion 480b of the variable link pin 480 can be efficiently guided to the insertion hole 162. The distal end portion 480 b of the link pin 480 can be easily positioned in the insertion hole 162. Therefore, the variable link pin 480 can be efficiently and easily guided to the insertion hole 162.

  Further, in the taper portion 480c, the span of the narrow portion between the distal end portion 480b and the base end portion 480a of the variable link pin 480 is changed from the span of the distal end portion 480b to the diameter of the base end portion 480a. It is what. Therefore, when the distal end portion 480b of the variable link pin 480 is inserted into the insertion hole 162, the base end portion 480a of the variable link pin 480 is fitted into the insertion hole 162 via the taper portion 480c of the variable link pin 480. The base end portion 480a of the variable link pin 480 can be smoothly inserted into the insertion hole 162. Further, the operator does not need to align the base end portion 480a of the variable link pin 480 and the insertion hole 162, and the workability is excellent.

  Further, when the front frame set 14 is opened with respect to the inner frame 12, the rotation axis J of the one-side opening mechanism 400 is set to the first position when the front frame set 14 is closed with respect to the inner frame 12. Since the rotary shaft displacement mechanism 420 that displaces to the second position P2 moved by a predetermined distance from the front side of the inner frame 12 to the other end side of the inner frame 12 from P1, the front frame set 14 is provided. When it becomes necessary to work with the inner frame 12 in a single-open state, the front frame set 14 has its rotational axis J on the front side of the inner frame 12 and on the other end side of the inner frame 12. It is opened from the inner frame 12 so as to move by a predetermined distance. In other words, one end side of the front frame set 14 (the rotation axis J of the single opening mechanism 400) is moved by a predetermined distance toward the front side and the other end side of the inner frame 12, so that the front frame set 14 is a piece. The amount of protrusion of the front frame set 14 with respect to another gaming machine (pachinko machine) adjacent to the rotating shaft J side can be suppressed. For the player who plays with the other pachinko machine, the open front frame set 14 is prevented from interfering with or intimidating the game, and the front frame set 14 is opened. It is possible to suppress the decline in the fun of playing games.

  Specifically, as shown by a broken line in FIG. 38, in the case of the single opening with the conventional fixed rotating shaft method, the front frame set with respect to the other adjacent pachinko machine 10 (the left pachinko machine 10 in FIG. 38). The amount of protrusion 14 is indicated by a broken line in FIG. On the other hand, in the pachinko machine 10 of the present embodiment, the protrusion amount of the front frame set 14 relative to the other adjacent pachinko machine 10 (left pachinko machine 10 in FIG. 38) is shown by a solid line in FIG. As shown, it is suppressed by the length of the distance d. Therefore, for the player who plays with the other pachinko machine 10, the open front frame set 14 is prevented from interfering with the game or intimidating, and the front frame set 14 is opened. It is possible to suppress a decrease in the fun of the game due to the fact. This is also beneficial when the front frame set 14 has a shape protruding to the front side. In other words, the amount of projection on the front side of the front frame set 14 with respect to another game machine (pachinko machine) adjacent to the rotation axis J side can be suppressed, and for a player who plays with the other pachinko machine. It is possible to prevent the protruding portion of the opened front frame set 14 from interfering with the game or giving an intimidating feeling.

  In addition, since one end side of the front frame set 14 (the rotation axis J of the one-side opening mechanism 400) has been moved by a predetermined distance toward the front side and the other end side of the inner frame 12, the front frame set 14 can be opened sufficiently, and the poor working environment due to insufficient opening of the front frame set 14 can be improved.

  In addition, a rectangular card unit (also called a ball lending unit or card sand) that is vertically long in front view may be disposed on the side (left end side) of the pachinko machine 10. In this card unit, a card (recording medium) storing balance information (for example, balance amount) data is inserted, the balance information (for example, balance amount) data of the inserted card is read, and based on this balance information One for renting game balls. Thus, in the case where the card unit is provided on the side of the pachinko machine 10, in the conventional pachinko machine, the front side of the front door that protrudes from the card unit hits the card unit, and the front door that has a shape protruding to the front side is opened. However, the pachinko machine 10 according to the present embodiment can reduce such a problem. That is, one end side of the front frame set 14 (the rotation axis J of the one-side opening mechanism 400) is moved by a predetermined distance toward the front side of the inner frame 12 and toward the other end side. 14 can be opened sufficiently, and it can be reduced that the opening of the front frame set 14 having a shape protruding to the front side is restricted by the card unit.

  In addition, the rotation axis displacement mechanism unit 420 moves the rotation axis J of the inner frame 12 in a predetermined section of the trajectory that displaces the rotation axis J of the single opening mechanism unit 400 from the first position P1 to the second position P2. Since it is displaced in an oblique direction inclined to the other end on the front side, the front frame set 14 can be pulled out in the oblique direction to be in a one-open state.

  In addition, since the inner frame 12 is provided with a game board 30 at a predetermined location inside, the front frame set 14 can be used when work needs to be performed on the game board 30 inside the inner frame 12. Although the inner frame 12 is in a single-opened state, the same effect as described above is obtained even when the front frame set 14 is opened in this manner and the game board 30 is operated.

  Further, the front frame set 14 includes an upper plate 19 for storing game balls at a position below the glass 137, so that it is necessary to work on the game board 30 inside the inner frame 12 or the like. In this case, the front frame set 14 is set in a state of being opened one side with respect to the inner frame 12. Have Moreover, it is still useful when the top plate 19 of the front frame set 14 has a shape protruding to the front side.

  Further, the front frame set 14 is detachable from the inner frame 12, and the rotary shaft displacement mechanism unit 420 of the single opening mechanism unit 400 is in a state where the front frame set 14 is detached from the inner frame 12. Since the rotation axis J is configured to be returned and held from the second position P2 to the first position P1, the front frame set 14 is opened to the inner frame 12 in a single-open state. Is removed from the inner frame 12, the rotational axis J of the single opening mechanism 400 is not left protruding in the second position P2, but the rotational axis J of the single opening mechanism 400 is moved to the first position. The state can be returned to P1, and the state returned to the first position P1 can be maintained. As a result, it is possible to solve the problem that the rotation axis J of the one-side opening mechanism portion 400 remains in the state of protruding to the second position P2. Further, the rotation axis J of the single opening mechanism 400 is returned to the first position P1, that is, the single opening mechanism 400 can be accommodated toward the inner frame 12, so that the pachinko machine with the front frame set 14 removed is provided. When the machine is moved, the rotating shaft J of the single-opening mechanism unit 400 protrudes to the second position P2, and the protruding single-opening mechanism unit 400 is caught on something during the movement, so that the single-opening mechanism unit 400 or It is possible to prevent the other party from being damaged. Further, since the single opening mechanism 400 can be stored toward the inner frame 12, when the pachinko machine with the front frame set 14 removed is stored in the storage box, the protruding single opening mechanism 400 is It does not become difficult to be stored by being caught in the box, can be easily stored in the storage box, and the single-opening mechanism 400 is not damaged during transportation.

  Further, the single opening mechanism 400 has a plurality of (this embodiment) arranged side by side on the rotation axis J at one end side (left end side in FIG. 3) of the front frame set 14 as the rotation axis J. In this case, the front frame set 14 is supported by one rotation with two rotation support shafts. Therefore, the front frame set 14 is supported by one opening at one end of the front frame set 14 as compared with the case where the front frame set 14 is supported by one opening. The distortion at the time of 14 one-sided opening can be reduced.

  Further, since the spring 490 is provided to urge the rotating shaft J of the one-side opening mechanism 400 in the state displaced to the second position P2 to be held at the second position P2, the front frame set 14 is attached to the inner frame 12. When the front frame set 14 is removed from the inner frame 12 in a single-open state, the rotary shaft J of the single-open mechanism 400 can be held in a state of protruding to the second position P2. That is, the rotation axis J of the one-side opening mechanism 400 can be held so as not to fluctuate, and the one end side of the front frame set 14 can be easily positioned and attached to the rotation axis J of the one-side opening mechanism 400. The front frame set 14 can be easily attached to the inner frame 12.

  In addition, since the plurality of springs 490 (two in the present embodiment) are provided for each of the rotation support shafts, the front frame set 14 is set in a single-open state with respect to the inner frame 12. When 14 is removed from the inner frame 12, each rotation support shaft of the single opening mechanism 400 can be held in a state of protruding to the second position P2. In other words, each rotation support shaft of the single opening mechanism 400 can be held at the second position P2 (held on the rotation axis J line), and the front frame set 14 is placed on each rotation support shaft of the single opening mechanism 400. Therefore, the front frame set 14 can be easily attached to the inner frame 12.

  The rotating shaft displacement mechanism 420 also includes a first guide hole 431 that connects a third position P3 that is a specific distance away from the first position P1 and a fourth position P4 that is a specific distance away from the second position P2 as described above.

The mounting substrate 430, the first sliding portion 441 that slides in the first guide hole 431 from the first position P1 to the second position P2, and the second guide hole 432 are close to the first guide hole 431. A second sliding portion 442 that slides away from the side, and is provided so as to be located at both ends of the line segment, and closer to one end on the front side of the inner frame 12 from the first sliding portion 441 A movable link 440 having an extended portion 443 that is extended, and rotating with respect to the extended portion 443 A demounting connection plate 450 having a rotation shaft portion 451 attached to the function and a protrusion 452 protruding in a predetermined direction from the rotation shaft portion 451, and one end at the protrusion 452 of the desorption connection plate 450. A variable link 460 that is pivotably attached and the other end of which is pivotally attached to a predetermined portion of an end portion of the mounting substrate 430 near the second guide hole 432, and pivoting of the detachable connecting plate 450 And a slide link pin 470 corresponding to an axis for opening and closing the front frame set 14 provided on the shaft portion 451, and the support fittings 81 and 82 have a longitudinal direction in the rotation axis J direction. The mounting plate 151 and 152 are provided with a variable link pin 480 provided on the protruding portion 452 of the detachable connecting plate 450, and the mounting plates 151 and 152 are externally fitted with a notch 160 for external fitting on the outer peripheral portion of the slide link pin 470. , Variable phosphorus The mounting plates 151 and 152 are slid in a state where the insertion hole 162 fitted to the base end portion 480a of the pin 480 for use and the outer notch 160 are fitted on the outer periphery of the slide link pin 470. And a guide member 164 for guiding the distal end portion 480b of the variable link pin 480 to the insertion hole 162 by rotating the link pin 470 in the direction approaching the variable link pin 480.

  Therefore, when an operator pulls the front frame set 14 forward so that the front frame set 14 is in a single-opened state with respect to the inner frame 12, first, the fixed link is rotated around the other end of the variable link 460. One end of the moving shaft starts to rotate counterclockwise. As the variable link 460 rotates, the protruding portion 452 of the detachable connecting plate 450 starts to rotate clockwise while being pulled out toward the front side, and the rotating shaft portion 451 of the detachable connecting plate 450 further rotates. Is pulled out toward one end of the variable link 460 while rotating clockwise. Further, the first sliding portion 441 of the movable link 440 slides from the third position P3 to the fourth position P4 in the first guide portion in accordance with the withdrawal of the detachable connecting plate 450, and the second of the movable link 440 is moved. The sliding portion 442 slides in the second guide hole 432 from the side closer to the first guide hole 431 to the side farther from the side closer to the first guide hole 431. As the movable link 440, the end near the second sliding portion 442 is provided. While sliding in the width direction of the inner frame 12, it slides in an oblique direction (a direction closer to the other end on the front side of the inner frame 12) such that the end close to the first sliding portion 441 moves toward the fourth position P <b> 4. The posture is changed. Moreover, while the 1st sliding part 441 of the movable link 440 slides from the 3rd position P3 of the 1st guide hole 431 to the 4th position P4, the attachment / detachment connection plate 450 is rotating clockwise, The attachment / detachment connecting plate 450 is rotated clockwise to an angle at which the front frame set 14 is in a single-open state with respect to the inner frame 12. Accordingly, the front frame set 14 is opened from the inner frame 12 so that the rotation axis J is moved by a predetermined distance toward the front side of the inner frame 12 and toward the other end side of the inner frame 12. In other words, one end side of the front frame set 14 (the rotation axis J of the single opening mechanism 400) is moved by a predetermined distance toward the front side and the other end side of the inner frame 12, so that the front frame set 14 is a piece. It is open. More specifically, the first sliding portion 441 of the movable link 440 is slid from the third position P3 to the fourth position P4, and the front frame set 14 is single-opened. From this, one structure which can suppress the protrusion amount of the front frame set 14 with respect to the other pachinko machine 10 adjacent to the rotation axis J side can be specifically realized.

  Furthermore, in a state where the outer fitting cutout portion 160 of the mounting plates 151 and 152 is externally fitted to the outer peripheral portion of the slide link pin 470 of the detachable connecting plate 450, the mounting plates 151 and 152 are moved to the slide link.
