[First Embodiment]
Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail with reference to the drawings. FIG. 1 is a front view of a pachinko machine 10, and FIG. 2 shows a lower plate unit in which a front frame set 14 serving as a front door is opened with respect to an outer frame 11 described later and an inner frame 12 serving as a support frame. It is a perspective view showing the state where 13 was removed. However, in FIG. 2, for the sake of convenience, a configuration in a game area on the surface of the game board 30 to be described later is shown in blank.

  As shown in FIG. 6, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is supported at one side of the outer frame 11 so as to be openable and closable. . The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, the structure can be easily reused as compared with the conventional structure in which the plates are assembled using nails and rivets. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm).

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

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

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

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

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

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

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

  Next, the configuration of the game board 30 will be described with reference to FIG. In the game board 30, a general winning port 31, a variable winning device 32, a first opportunity corresponding port (starting port) 33, a second opportunity corresponding port (through gate) 34, a variable display unit 35 and the like are formed by router processing. The game board 30 is attached from the front side with a wood screw or the like. As is well known, a game ball enters the general winning opening 31, the variable winning apparatus 32, and the first opportunity corresponding opening 33, and a predetermined number of prizes are given to the upper plate 19 (or the lower plate 15) by the output of a detection switch described later. The ball is paid out. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning units (winning device, winning port, first opportunity corresponding port 33, etc.) pass through the out port 36. Then, it is guided toward a ball discharge path (not shown). A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (functions) such as the windmill 27 are arranged.

  The variable display device unit 35 includes a normal symbol display device 41 that variably displays a normal symbol with the passage of the second trigger corresponding port 34 as a trigger, and a special symbol as identification information with a winning at the first trigger corresponding port 33 as a trigger. And a special symbol display device 42 as a symbol display device for variably displaying.

  The normal symbol display device 41 includes a normal symbol display unit 43 and a holding lamp 44, and the display symbol (ordinary symbol) by the display unit 43 changes each time the game ball passes through the second opportunity corresponding port 34, for example. However, the first opportunity corresponding port 33 is configured to be activated (opened) for a predetermined time when the change display stops at a predetermined symbol. When a game ball newly passes through the second opportunity corresponding port 34 during the normal symbol fluctuation display on the display unit 43 of the normal symbol display device 41, the normal symbol fluctuation display for that time is displayed at that time. The configuration is performed after the end of the variable display. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. ing. However, the maximum number of holding times is not limited to this. For example, the maximum number of holdings may be set to 8 in order to wait for the normal symbol variation display for 8 times. The display unit 43 may be configured to be variably displayed on a part of the special symbol display device 42 (liquid crystal display device) in addition to a configuration that is variably displayed by switching lighting of a plurality of lamps. Similarly, the hold lamp 44 may be configured to be displayed on a part of the special symbol display device 42.

  The special 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 special 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 special symbol display device 42 so as to be scrolled for each symbol row. In the present embodiment, the special symbol display device 42 (liquid crystal display device) includes a large liquid crystal display of 8 inches size. The variable display device unit 35 is provided with a center frame 47 so as to surround the special symbol display device 42.

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is likely to win in a big hit (occurrence of a special game state) and a normal closed state. It is designed to be operated repeatedly. More specifically, when the game ball wins the first opportunity corresponding port 33, the special symbol display device 42 displays the symbols in a variable manner, and the confirmed symbol after the stop needs to be a combination of specific symbols set in advance. A special gaming state occurs in the condition. The large winning opening of the variable winning device 32 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win a prize (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times. When a new game ball wins the first opportunity corresponding port 33 during the symbol variation display of the special symbol display device 42, the corresponding symbol variation display is performed after the symbol variation display being performed at that time ends. It is configured to be performed. That is, the symbol variation display is waited (held, stored). Although the maximum number of symbol variation displays to be held is determined for each pachinko machine model, in this embodiment, up to 4 times are held, and the number of times the hold is held is displayed by the hold lamp 46. It has become. However, the maximum number of holding times is not limited to this. For example, the maximum number of suspensions may be set to 8 in order to wait for 8 symbol fluctuation displays. The hold lamp 46 may be configured to be displayed on a part of the special symbol display device 42.

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

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

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

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

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

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

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

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

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

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

  In addition, the 2nd opportunity corresponding | compatible opening 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 opportunity corresponding | compatible opening 34 is approached toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the first first opportunity corresponding port 33 and the variable winning device 32. By expanding, it is possible to suppress a decrease in interest due to difficulty in winning a game ball. Furthermore, the game area is expanded in the left-right direction, so that the second opportunity corresponding port 34, the windmill 27, a plurality of nails (guide nails for guiding the game ball to the center), and various other objects 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 gaming area is also expanded in the vertical direction, the second opportunity corresponding port 34, the windmill 27, a plurality of nails, and other accessories can be arranged in various ways. 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 is attached. Yes. The firing rail 61 is fixedly attached to the resin base 20 integrally with the metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball that is launched in accordance with the turning operation of the handle 18 is first launched obliquely upward along the launch rail 61 and then guided to a predetermined game area through the ball guide passage of the rail unit 50 as described above. It is like that.

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

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

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

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

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

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

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

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

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

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

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

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game 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 to which a transparent resin is attached is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102.

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

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

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

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

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

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

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

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

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

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

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

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

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. In the pachinko machine 10, various control boards are arranged on the back side (actually the back side of the inner frame 12 and the game board 30) so as to be arranged vertically or horizontally, or to be stacked in front and back, A game ball supply device (payout mechanism) for supplying game balls, a protective cover made of resin, and the like are attached.

The backpack unit 203 is fixedly held to the main body of the pachinko machine by the fastening part M7 and the locking parts M8, M9.

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

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

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

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

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, corresponding to the game board opening of the above-described general winning opening 31, variable winning apparatus 32, first opportunity corresponding opening 33 (see FIG. 3 respectively) and 1 on the downstream side. A collection passage 216 that collects at a place is formed. In addition, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is also attached to the inner frame 12 below the game board 30, and discharge balls are sent to the outside of the pachinko machine 10 in the discharge passage board 217. A discharge passage 218 for guiding is formed. Therefore, as illustrated in phantom lines in FIG. 8, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further the discharge passage 218 of the discharge passage board 217. Through the pachinko machine 10. In addition, the out port 36 (see FIG. 3) similarly communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

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

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

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

  The prize opening switch 221 and the second opportunity corresponding gate (gate) switch 225 are connected to the board relay board 226 through electric wiring (not shown), and this board relay board 226 is further connected to a main board (main controller 261) described later. ing. Further, the specific area switch 222 and the count switch 223 are connected to the special winning opening relay board 227, and the special winning opening relay board 227 is also connected to the main board. On the other hand, the first opportunity corresponding port (starting port) switch 224 is directly connected to the main board without passing through the relay board.

  Although not shown in the drawings, the variable winning device 32 is provided with a large winning opening solenoid for opening the large winning opening and a winning ball distribution plate solenoid for guiding the winning ball to a specific area. The corresponding port 33 is provided with a first opportunity corresponding port (starting port) solenoid for opening the electric accessory. In FIGS. 8 and 9, reference numeral 228 denotes a set handle including a hitting ball and the like, and reference numeral 229 denotes a firing motor.

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

  The back frame set 215 is provided with an attachment mechanism for attaching the first control board unit 201. Specifically, as this attachment mechanism, a support bracket 231 extending in the vertical direction is provided at the lower left corner when viewed from the back of the game board 30, and the support bracket 231 has a pair of upper and lower support holes on the same axis. Is formed. In addition, in the lower right part of the game board 30, reference numeral 232 is a pair of upper and lower fastening holes (ny latch holes), and in the upper left part, reference numeral 233 is a locking claw piece.

  An attachment mechanism for attaching the second control board unit 202 and the back pack unit 203 is provided on the back surface of the inner frame 12. Specifically, a long support fitting 235 is attached to the inner frame 12 at its right end, and its configuration is shown in FIG. As shown in FIG. 10, the support metal fitting 235 has a long plate-like metal fitting main body 236, and the support hole 237 for the second control board unit is formed at two lower positions so as to stand up from the metal fitting main body 236. At the same time, support hole portions 238 for the back pack unit are formed at two upper positions. Coaxial support holes are formed in the support hole portions 237 and 238, respectively. In addition, as an attachment mechanism for the second control board unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (ny latch holes) 239 at the left end below the game board installation area. As a mounting mechanism for the back pack unit, the inner frame 12 is provided with a pair of upper and lower fastening holes (nylatching holes) 240 at the left end of the game board installation area. However, the support bracket for the second control board unit and the support bracket for the back pack unit can be provided as separate members. Reference numerals 241, 242, and 243 denote rotational fixtures for sandwiching and supporting the back pack unit 203 with the game board 30.

  In addition, in the rear configuration of the inner frame 12, a game ball for distributing a game ball paid out from a payout mechanism, which will be described later, to either the upper plate 19, the lower plate 15, or the discharge passage 218, at the lower right portion of the game board 30. A distribution unit 245 is provided. That is, the opening 245a of the game ball distributing unit 245 communicates with the upper plate 19, the opening 245b communicates with the lower plate 15, and the opening 245c communicates with the discharge passage 218 (see FIG. 9). Conventionally, since a portion corresponding to the game ball distributing unit 245 is provided on the back pack unit 203 side, the back pack unit 203 is pushed through the ball discharge port (ball passage wall 69 in FIG. 2) reaching the upper plate 19. As a result, a gap is formed between the inner frame 12 and a portion corresponding to the game ball distributing unit 245, and an illegal act of inserting a wire or the like through the gap and operating the internal device has been considered. Therefore, in the pachinko machine 10, such illegal acts are prevented by providing the game ball distribution unit 245 on the inner frame 12 side and fixing the game ball distribution unit 245 by a fixing means. Further, the upper end surface of the game ball distributing unit 245 is formed in accordance with the height position where the lower end surface of the game board 30 is installed, and is devised so as not to prevent the game board 30 from being removed.

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

  Next, the first control board unit 201 will be described with reference to FIGS. FIG. 11 is a front view of the first control board unit 201, and FIG. 12 is a perspective view of the unit 201.

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 261 and the sound lamp control device 262 are mounted on the mounting base 251. Here, the main control device 261 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and various lotteries. A main board including a random number generator used, a clock pulse generation circuit used for time counting and synchronization, etc., and the main board is made of a transparent resin material or the like; ). The structure of the substrate box 263 includes a box base 411 having a substantially rectangular parallelepiped shape and a box cover 410 that covers an opening of the box base 411. The box base 411 and the box cover 410 are connected to each other by a sealing unit 264 (sealing means) so that the substrate box 263 is sealed.

  As the sealing unit 264 as the sealing means, any configuration can be applied as long as it connects the box base 411 and the box cover 410 so that they cannot be opened, but here, as shown in FIG. The box base 411 and the box cover 410 are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the board box 263 is left in the board box 263, it can be easily found that the illegal opening has been performed by looking at the board box 263.

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

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

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

  By the way, when the board box 263 is mounted on the board mounting surface of the mounting base 251, the fitting part of the board box 263 provided correspondingly is fitted into the mounting part 460 provided above the board mounting surface. It is. This fitting structure is a characteristic part of the present embodiment. First, the structure of the fitting portion will be described below.

  Fig.13 (a) is explanatory drawing which shows the schematic partial cross section in the AA of FIG. Moreover, FIG.13 (b) is a decomposition explanatory drawing for showing the structure of the fitting part 412 of Fig.13 (a). As described above, the substrate box 263 includes the box base 411 and the box cover 410, and accommodates the main substrate. The main board is accommodated at the position indicated by the symbol H, but the main board itself is omitted. Further, in order to explain the structure on the board box 263 side, the mounting portion 460 of the mounting base 251 is also omitted.

  The fitting portion 412 has a width in the left-right direction slightly smaller than that of the mounting portion 460. The fitting front portion 420 protrudes upward from the box base 411 and a screw 440 on the back side of the box base. And a fitted rear portion 430 to be fixed. The fitting front part 420 and the fitting rear part 430 are arranged apart from each other in the front-rear direction.

  The fitting front portion 420 includes a flat surface 421 on the front surface side, and the upper portion of the flat surface 421 is inclined to the back surface side by about 45 degrees, and a groove portion 422 is formed. Further, a ridge portion 423 that protrudes toward the front side with respect to the groove portion 422 is formed immediately above the groove portion 422. On the other hand, a recess 424 and a groove 425 are formed on the back side of the fitting front part 420. The recessed part 424 and the groove part 425 are provided in the back side part just corresponding to the flat surface 421, the recessed part 424 is provided in the upper position, and the groove part 425 is provided in the lower position. On the other hand, a concave portion 431 is formed in the mating rear portion 430 at a position facing the concave portion 424 of the mating front portion 420.

  As will be described later, a dedicated key 470 (see FIG. 14D) is inserted from the front side of the mating front portion 420 to release the mated state. Therefore, a through hole is formed in the recess 424, and a key hole is formed in the recess 431. In the drawing, in order to avoid complication, the through holes and the key holes are omitted. In addition, a coil spring 450 is disposed between the recesses 424 and 431, and urges the engagement front portion 420 and the engagement rear portion 430 to be spaced apart from each other at a predetermined position. Further, a cavity 426 is provided on the front side of the recess 424. In the flat surface 421, an insertion hole for inserting the dedicated key 470 is formed corresponding to the hollow portion 426. The insertion hole is a long hole that is long in the vertical direction.

  The fitting portion 412 formed in this way is fitted into the mounting portion 460 of the mounting base 251 as described above, and the board box 263 is mounted on the board mounting surface of the mounting base 251.

  Then, next, the fitting to the attachment part 460 and the cancellation | release of a fitting are demonstrated using FIG.

  As shown in FIG. 14A, the attachment portion 460 has a substantially U-shaped cross section with the lower portion opened, and the attachment portion 460 is attached by inserting the fitting portion 412 from the opened lower portion. Performed (sliding in the direction indicated by symbol J).

  In addition, an inclined surface 461 that is inclined at about 45 degrees toward the back side is provided on the inner wall on the front surface side of the attachment portion 460, and the ridge portion 462 that follows the inclined surface 461, and the ridge portion 462. A groove 463 is formed immediately above.

  Therefore, as shown in FIG. 14B, the protrusion 423 of the fitting front part 420 abuts on the inclined part 461, and the fitting front part 420 becomes the fitting rear part 430 due to the reaction force from the inclined surface 461. Move to the side (move in the direction indicated by symbol K). This movement is caused by the fitting front portion 420 being bent by the concave portion 435 formed in the lower portion of the fitting front portion 420.

  Further, when the fitting portion 412 is further inserted upward, as shown in FIG. 14C, the protrusion 423 of the fitting front portion 420 is fitted into the groove portion 463 of the attachment portion 460, and the protrusion of the attachment portion 460 is projected. The strip portion 462 is fitted into the groove portion 422 of the fitting front portion 420, and the fitting portion 412 is fitted and fixed. At this time, the mating front part 420 and the mating rear part 430 are biased to be separated from each other by the coil spring 450 (biased in the direction indicated by the symbol L if the mating rear part 430 is used as a reference). The fitting state is maintained. In this fitted state, the downward movement of the fitting portion 412 is restricted, and it is not always possible to remove it. Although not shown, since the attachment portion 460 has a structure that covers the back side of the rear portion 430 to the lower side, the above-described screw 440 (see FIG. 13) cannot be removed.

  On the other hand, when the board box 263 is removed from the mounting base 251, the dedicated key 470 is used as shown in FIG. The dedicated key 470 has a handle part 471, a notch part 472, a locking end part 473, and a key part 474.

And the key part 474 is provided through the latching end part 473 which protrudes in an up-down direction.

  A through hole 464 is formed on the front surface side of the attachment portion 460 so as to correspond to the insertion hole of the fitting front portion 420. As shown in FIG. 14 (d), when the operator inserts the dedicated key 470 from the through hole 464 (when inserted in the direction indicated by the symbol M), the locking end 473 is formed in the cavity portion of the fitting front portion 420. 426 is entered, and this locking end 473 acts on the mating front part 420, and the mating front part 420 moves to the back side. In this state, the key portion 474 is inserted into the key hole of the fitting rear portion 430, and the dedicated key 470 can be rotated to a predetermined position.

  When the dedicated key 470 is rotated to a predetermined position, the engaging end portion 473 protruding in the vertical direction forms a predetermined angle with respect to the vertical direction. When the dedicated key 470 is further rotated, the dedicated key 470 is cut into two at the notch 472. As a result, the distal end side member closer to the distal end than the locking end portion 473 is locked by the fitting portion 412 and cannot be taken out. For example, the key part 474 is locked in the key hole of the fitting rear part 430. At this time, the mating front part 420 and the mating rear part 430 are brought into close proximity to each other and the mating is released. Therefore, the board box 263 can be removed from the mounting base 251.

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

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

  Further, the reach random number counter C3 is configured to increment one by one within a range of 0 to 238, for example, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach lottery may be set individually according to the state of the lottery probability of the special symbol display device 42, the number of starting reserved balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding 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 special symbols 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 (book) In the embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol.

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

  The left, middle and right off symbol counters CL, CM, CR are the stop symbols of the left column special symbol, the middle column special symbol, and the right column special symbol when the special symbol display device 42 is not selected. Since any one of 10 special symbols is displayed in each column, 10 counter values (0 to 9) are prepared for each. The stop symbol of the left symbol row is determined by the off symbol counter CL, the stop symbol of the middle symbol row is determined by the off symbol counter CM, and the stop symbol of the right symbol row is determined by the off symbol counter CR.

  In this embodiment, the value of each counter CL, CM, CR is updated at random by using the value of the built-in R register in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, 10 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated within the normal 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 the variation of the special symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear out, and the complete out symbol symbol buffer is acquired according to the value of the reach random number counter C3. .

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

  Although not shown, the normal symbol random number counter C4 is used for the lottery of the normal symbol display device 41. The normal 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 normal symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and is acquired when the game ball passes through the left or right second opportunity corresponding port 34. The number of random number values to be won is 149, and the range is “5 to 153”.

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

  FIG. 28 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 261 every 2 msec, for example.

  In FIG. 28, first, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

  Thereafter, in step S602, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In subsequent step S603, the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in this embodiment, 676, 49, and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

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

  In the subsequent step S704, a random number related to the special symbol winning 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. Then, after the start winning process, the CPU 501 once ends the timer interruption process.

  FIG. 30 is a flowchart showing the NMI interrupt processing. This processing is executed by the CPU 501 of the main control device 261 when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503.

  That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 261. Then, the CPU 501 interrupts the control being executed and starts the NMI interrupt process of FIG. The NMI interrupt processing in FIG. 30 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal SK1 is output, current is supplied from the power supply unit 541 so that the processing of the main control device 261 can be executed, and the NMI interrupt processing is executed within the predetermined time.

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

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

  The NMI interrupt process is also executed in the payout control device 311 in the same manner, and the state of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Similarly, the power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SK1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process in FIG. 30 is started. The contents are as described in FIG. 30 (however, the transmission of the power-off notification command in step S804 is excluded).

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

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

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

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

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

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

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

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

  The update process of each out symbol counter CL, CM, CR will be described in detail. As shown in FIG. 25, in step S301, it is determined whether or not it is time to update the out symbol counter CL in the left symbol row. In step S302, It is determined whether or not it is time to update the middle symbol row out of symbol counter CM. If the update timing of the left symbol 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 out symbol counter CR of the right symbol sequence is updated. In updating the out-of-step symbol counters CL, CM, and CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 10 is subtracted when the addition result exceeds the maximum value, The calculation result is set as the current value of the off 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 out of reach, the process proceeds to step S308, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear out of reach symbol buffer of the RAM 503. If the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step 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. To do.

  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, 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, CR are stored in the buffer. The process is terminated without any processing.

  After the off symbol counter updating process, in step S204 in FIG. 24, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. After that, in step S205, special symbol variation processing for performing special symbol variation display by the special symbol display device 42 is executed. With this special symbol variation processing, jackpot determination, special symbol variation pattern setting, and the like are performed. However, details of the special 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 32 is executed in the case of a big win state. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S207, normal symbol display control by the normal symbol display device 41 is executed. Briefly, on the condition that the game ball has passed through the second opportunity corresponding port 34, the normal symbol random number counter C4 is acquired and the normal symbol lottery is performed on the display unit 43 of the normal symbol display device 41. When the normal symbol is hit, the first opportunity corresponding port 33 is opened for a predetermined time. Although explanation is omitted, the normal symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 28, like the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3. .

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

  In step S210, update of the variation type counters CS1 and CS2 is executed (same as step S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the change values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503.

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

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

  In FIG. 26, in step S401, it is determined whether or not it is a big hit now. Note that the jackpot includes a special game displayed on the special 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 special symbol display device 42 is displaying the variation of the special symbol. If the special symbol display is not being changed and the variation is not being displayed, the process proceeds to step S403, where it is determined whether or not the number N of starting reserved balls of the special symbol display device 42 is greater than zero. At this time, if it is a big hit or if the number N of starting reserved balls is 0, this processing is terminated as it is.

  Further, if it is neither a big hit nor a special symbol variation display, and if the number of starting reserved balls N> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of starting reserved balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

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

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

  Next, in step S503, the variation pattern at the time of the big hit is determined, and the variation pattern is set in the variation pattern command. At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are confirmed, and the reach type of a special symbol such as normal reach, super reach, premium reach, etc. based on the value of the first variation type counter CS1. And other rough symbol variation modes, and the elapsed time until the final stop symbol (in this embodiment, the middle symbol) stops after occurrence of reach based on the value of the second variation type counter CS2 (in other words, variation More detailed symbol variation mode is determined. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like.

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

  If front / rear out of reach has occurred, the process proceeds to step S506, and the left, middle, and right out of symbol counters CL, CM, 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. The reach type of the special symbol and other rough symbol variation modes are determined, and the final stop symbol (the middle symbol in the present embodiment) is stopped after the reach occurs based on the value of the second variation type counter CS2. A more detailed symbol variation mode such as the elapsed time (in other words, the number of variation symbols) is determined.

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

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

  Returning to the description of FIG. 26, if step S402 is YES, that is, if the special symbol is being fluctuated, the process proceeds to step S407 to determine whether or not the fluctuating time has elapsed. At this time, the variation time of the special symbol is determined according to the variation pattern of the special symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a stop symbol set for stopping and checking the fluctuation is set as a confirmation command, and then this process is terminated.

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

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

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

  If the RAM erase switch 323 is ON, the process proceeds to a RAM initialization process (step S915, etc.). Similarly, when the occurrence information of power interruption is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process similarly 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, CPU peripheral devices are initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

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

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

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

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 15. That is, when the lower pan 15 is detected based on the detection signal of the lower pan full switch, when the lower pan is full, the lower pan full state is set, and when the lower pan full is not reached , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and the special setting for the absence of the tank ball and the setting for the no tank ball state are executed. Perform configuration.

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

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

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

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

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

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

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

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

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

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

  Next, the effect which the pachinko machine 10 of this Embodiment exhibits is demonstrated.

  As described above, the present embodiment is characterized in that the fitting portion 412 is provided in the substrate box 253 and the attachment portion 460 is provided in the attachment base 251.

  Specifically, the fitting portion 412 includes a fitting front portion 420 and a fitting rear portion 430, and the fitting portion 412 is inserted from the lower portion into the mounting portion 460 whose lower portion is opened, whereby the board box 253 is inserted. Is completed (see FIGS. 14A to 14C). At this time, the mating front part 420 and the mating rear part 430 are urged to be separated from each other by the coil spring 450, and the mating state is maintained. As a result, a tool is not required at the attachment stage, and there is no possibility that the work efficiency of attaching the board box 253 will be reduced. Further, the coil spring 450 appropriately holds the fitting state. In this fitted state, the downward movement of the fitting part 412 is restricted, and it is not always possible to remove it.

  Then, when removing the board box 263 from the mounting base 251, it is necessary to use the dedicated key 470, as shown in FIG. 14 (d). Can be suppressed.

  Further, in the present embodiment, the dedicated key 470 is locked inside the mounting portion 460 by the insertion and rotation of the dedicated key 470, and at this time, the proximity of the fitting front portion 420 moving to the fitting rear portion 430 side. It will be in a state and a fitting state will be canceled. Therefore, it becomes difficult to remove without the rotatable dedicated key 470 following the insertion. In addition, the dedicated key 470 needs to have a structure that is locked inside the mounting portion 460. Also in this respect, it is difficult to remove the dedicated key 470 without the dedicated key 470. As a result, it is possible to effectively suppress malicious acts related to the main board.

  Furthermore, in the present embodiment, the dedicated key 470 is further rotated from the rotatable position, thereby being cut at the notch portion 472 and the front end side member being locked to the fitting portion 412. Therefore, even if the dedicated key 470 is configured to be locked inside the attachment portion 460, only the dedicated key 470 may be used, and it is not necessary to use a specific tool.

  Further, in the present embodiment, when the tip side member of the dedicated key 470 is locked to the fitting portion 412 of the board box 263, the locking end portion 473 remains in the cavity portion 426 of the fitting front portion 420. Therefore, it cannot be removed from the fitting portion 412. For this reason, when the board box 263 is once removed, the board box 263 itself must be replaced. Therefore, even if the dedicated key 470 is obtained, the board box 263 cannot be reattached, so that malicious actions related to the main board can be suppressed.

Furthermore, in the present embodiment, since the dedicated key 470 is provided with the key portion 474, malicious actions related to the main board can be effectively suppressed by changing the key shape. For example, if the key shape is different for each model, the effect is outstanding.
[Second Embodiment]
In the above embodiment, the dedicated key 470 is employed. On the other hand, in the second embodiment, a dedicated screw is used.

For example, as shown in FIG. 36, it is conceivable that the fitting front part 491 moves to the fitting rear part 492 side by fastening a dedicated screw 480 to the fitting rear part 492 with a tool, for example. In this case, an internal thread may be formed in the mating rear portion 492, and it is not necessary to form a key hole, which is advantageous in that the configuration is simplified. Even if the coil spring 493 is strong, the fitting state can be easily released by rotating the dedicated screw 480 and moving it forward.
[Third Embodiment]
In the above embodiment, the fitting portion 412 is provided on the upper portion of the substrate box 263 (see FIG. 11). On the other hand, in the third embodiment, the fitting portion 412 is provided on the left side portion of the board box, and the mounting portion of the corresponding mounting base accommodates the sealing unit 264 as well.

  As a result, in order to open the board box 263, it is necessary to remove the board box 253 from the mounting base 251. At this time, the dedicated key 470 is required, so that malicious actions related to the main board can be effectively suppressed.

  As mentioned above, this invention is not limited to the said embodiment at all, and it cannot be overemphasized that it can implement with a various form, unless it deviates from the meaning of this invention.

  For example, in the above embodiment, the substrate box 263 that accommodates the main substrate is targeted, but the present invention can be similarly applied to a substrate box that accommodates another control substrate.

  Further, in the above embodiment, the two fitting portions 412 are provided in the board box 263 so as to correspond to the mounting portion 460 of the mounting base 251. On the other hand, a plurality of fitting parts 412 such as two or four may be provided side by side so as to correspond to the attachment part 460 by shifting the board box 263 in the left-right direction. In this case, when the board box 263 is removed, the board box 263 can be attached using another fitting portion 412 by shifting the board box 263 in the left-right direction. The tip side member of the dedicated key 470 is locked by the fitting portion 412 and cannot be taken out, and remains as a history of removal of the board box 263, so that unauthorized removal of the board box 263 can be immediately found.

  For example, you may implement as a pachinko machine of a different type from the said embodiment. In addition to pachinko machines, the present invention can also be implemented as various gaming machines such as a slot machine as a revolving game machine, an arrange ball machine, and similar sparrow balls. The slot machine is a known machine in which, for example, a symbol is stopped and fixed by operating a control lever while inserting a coin and determining a symbol effective line. In this case, examples of the game medium include coins and medals. Moreover, you may implement as a game machine which the pachinko machine and the slot machine united. As a specific example, an identification information string composed of a plurality of identification information (specifically, a reel and identification information is a symbol attached to the reel) is variably displayed (specifically, a rotation of the reel). After that, variable display means for confirming and stopping the identification information is provided, and the fluctuation of the identification information is started due to the operation of the start operation means (for example, the operation lever), and the stop operation means (for example, the stop button) is operated. The special gaming state that causes the special gaming state advantageous to the player on the condition that the variation of the identification information is stopped due to or after a predetermined time elapses, and the confirmed identification information at the time of stopping is the specific identification information Generating means, using a game ball as a game medium, requiring a predetermined number of game balls at the start of variation of the identification information, and generating a large number of games at the occurrence of a special game state. One in which the ball is paid out.
