Description

  The present invention relates to a gaming machine.

  For example, some pachinko gaming machines are equipped with a symbol display device that variably displays multiple types of symbols on the display screen, and if a special gaming state advantageous to the player such as a big hit state occurs, a specific symbol A so-called reach effect is performed as a stage before the combination is determined and displayed. As an example, in a gaming machine in which symbols of three symbol sequences are set as one set and the variable display is started and the symbols of each symbol sequence are sequentially stopped, the same symbols of the two symbol sequences stopped first are set in advance. Reach display when stopped on the activated line. Then, after reaching the reach display, various reach effects are performed as appropriate, and when a special gaming state occurs, the same symbol in the final stop symbol sequence is further stopped on the active line that has reached the reach display, and the symbol is determined. Is displayed. Then, for example, a special winning opening is opened with the occurrence of the special gaming state.

  In such a gaming machine, it is likely that the player will watch the aspect on the display screen in the hope of the occurrence of a special gaming state at the time of reach production. Will play games without expectation, and may reduce their willingness to play. Moreover, even if it is a game time in which a reach effect occurs, the aspect on the display screen until the reach effect occurs tends not to attract much attention. Therefore, in such a game situation, in order to make the player pay attention to the aspect on the display screen, in a situation where all the symbols are variably displayed, the degree of expectation as to whether or not the reach display occurs in the game times is taught. Pachinko machines that perform reach expectation effects have also been proposed (see, for example, Patent Document 1).

However, the reach expectation effect proposed here is always performed in the same manner regardless of the reach effect that occurs thereafter, so it is monotonous and has little change. In this case, the player can guess whether the reach display is performed in the game times by visually recognizing the effect, but guesses what the reach display is performed after the effect. I can't do it. Therefore, the degree of expectation felt by the player by visually recognizing the effect will always be the same, and the degree of attention to the reach expectation effect will fade as the game continues to be played. . From the above, it can be said that the conventional reach expectation effect does not sufficiently raise the player's interest in the aspect on the display screen.

In this case, since the glass door frame and the front decoration frame are integrated into the front door frame 13, the strength of the glass support structure can be improved in the front door frame 13. That is, in this pachinko machine 10, for the purpose of expanding the game area, a large glass 137 is mounted on the front door frame 13 along with the expansion of the game area. Therefore, although the frame portion around the glass becomes narrow and there is a concern about the problem of strength reduction, sufficient strength of the glass support structure can be ensured by providing a frame portion integrated with the upper plate below the glass. The vertical and horizontal dimensions of the glass 137 are generally 405 mm × 405 mm, whereas the pachinko machine 10 has 453 mm × 434 mm.

  The front door frame 13 is extended downward so as not to interfere with the game ball launching handle 18 at least when opening and closing the front door frame 13. Specifically, the dimension La from the lower end of the pachinko machine to the lower end of the front door frame 13 is, for example, about 201 mm in the existing model, whereas the present pachinko machine 10 is about 30 mm smaller, about 172 mm. It has become. In addition, along with this, the dimension Lb from the lower end of the pachinko machine to the upper end of the upper plate 23 is also reduced, which is about 298 mm in the existing model, for example, is about 261 mm in the present pachinko machine 10. Here, by lowering the position of the upper plate 23, the vertical distance from the tip of the nozzle of the ball lending device provided side by side on the left side of the pachinko machine 10 in the game hall increases, and there is concern about spilled balls. However, in the present embodiment, the rising portion 22a in which the wall surface of the bulging portion 22 is made higher than the other wall surface is formed in the left side portion that is a rental ball discharge portion from the nozzle. Thereby, even if it has the structure which lowered the position of the top plate 23, inconveniences, such as spilling of a rental ball, are eliminated. The height of the raised portion 22a may be any as long as it matches the lowered size of the upper plate 23, and the maximum height is 25 mm in the present embodiment.

  In the front door frame 13, the bulging portion 22 for forming the upper plate is provided so as to largely bulge to the near side. ) Is restricted to bulge to the near side to avoid interference with the nozzle of the ball lending device. Specifically, the dimension from the outer frame 11 toward the front side is limited to 45 to 50 mm.

  As shown in FIG. 3, the main body frame 12 is mainly composed of a resin base 25 whose outer shape is substantially the same as that of the outer frame 11. A substantially circular window hole 26 is formed at the center of the resin base 25. Is formed. A game board 30 is detachably mounted on the rear side of the resin base 25. As shown in FIG. 4, the game board 30 is made of a substantially square plywood, and is attached in a state where the peripheral edge thereof is in contact with the back side of the resin base 25. That is, the game board 30 is attached from the rear of the pachinko machine 10, and only the substantially central portion of the front part of the game board 30 is exposed to the front side of the main body frame 12 through the window hole 26 of the resin base 25. Note that the gaming board 30 has a length in the vertical direction of 476 mm and a length in the horizontal direction of 452 mm, as in the prior art.

  Next, the structure of the game board 30 is demonstrated based on FIG. The game board 30 is formed with a plurality of large and small openings penetrating in the front-rear direction by being subjected to router processing. Each opening is provided with a general winning port 31, a variable winning device 32, an operating port 33, a through gate 34, a variable display unit 35, and the like. Actually, the general winning port 31, the variable winning device 32, the operating port 33, the through gate 34, and the variable display unit 35 are attached to the surface of the game board by wood screws or the like. In the present embodiment, the variable display unit 35 is disposed substantially at the center of the game board 30, the operation port 33 is disposed below the variable display unit 35, and the variable winning device 32 is disposed further below.

The operating port 33 is additionally provided with an electric accessory that is activated (opened) under a predetermined condition. When a game ball enters the general winning port 31, the variable winning device 32, and the operating port 33, it is detected by a detection switch described later, and based on the detection result, the upper plate 23 (in some cases, the lower plate 16) is detected. A predetermined number of prize balls are paid out. In addition, an out port 36 is provided at the lowermost part of the game board 30 so that game balls that have not entered various winning ports etc. are guided through the out port 36 toward a ball discharge path (not shown). It has become. The out port 36 is formed by cutting out the substantially lower center of the game board 30 in an inverted U shape. Therefore, compared to the conventional configuration in which the out port is formed in a hole shape, the out port can be easily formed (however, in FIG. 4, the rail unit 50 is provided on the front side so that the out port 36 is closed. Is shown). The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (functions) such as a windmill 37 are disposed.

  Notches 38 as recesses are formed at a plurality of locations on the left and right sides of the game board 30 so as to avoid interference with the protruding regions from the left and right sides of the body frame 12 that is the assembly partner.

  As described above, in the pachinko machine 10, the position of the upper plate 23 is lowered, and accordingly, the position of the game ball intake port provided in the most downstream portion of the upper plate 23 is also lowered. In this case, in the conventional configuration in which the game ball inlet is at a relatively high position, the game ball inlet and the game board 30 overlap each other, and the game board 30 has a notch corresponding to the game ball inlet. In this pachinko machine 10, the game ball intake port and the game board 30 do not overlap each other by lowering the game ball intake port. No formation is necessary. Therefore, it becomes an advantageous configuration in the manufacturing process of the game board 30.

  The variable display unit 35 is provided with a first symbol display device 41 for variably displaying the first symbol (special symbol) with a winning at the operation port 33 as a trigger. A center frame 43 is disposed in the variable display unit 35 so as to surround the first symbol display device 41. On the upper part of the center frame 43, a holding lamp 44 corresponding to the first symbol display device 41 is provided.

On the first symbol display device 41, for example, the first symbols are displayed side by side in the top, middle and bottom, and these symbols are variably displayed as they are scrolled in the horizontal direction. In addition, the 1st symbol display device 41 is equipped with liquid crystal displays of 10 inches other than 8 inches, 7 inches, etc., equipped with a wide size display, or other types such as CRT, dot matrix, 7 segments, etc. A display screen may be configured.

  The 2nd symbol display apparatus 42 is provided with the display part 45 which displays 2 types of 2nd symbols, for example, "(circle)" and "x". When the game ball passes through the through gate 34, the display symbol (second symbol) of the display unit 45 fluctuates, and when the variation display stops at a predetermined symbol (for example, “◯” symbol), the operation port 33. The electric accessory attached to is configured to be open for a predetermined time. Specifically, when the game ball passes through the through gate 34, each LED built in the back of the portion marked with “O” and “X” is alternately lit, and finally “O Only “LED” corresponding to one of “X” and “X” is turned on. The display unit 45 is configured to be variably displayed by alternately lighting a plurality of lamps (LEDs), or to be variably displayed on a part of the first symbol display device 41 (liquid crystal display device). There may be.

  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 switched to a predetermined open state in which the game ball is likely to win in a special game state (hereinafter referred to as a jackpot). It has become. More specifically, when a game ball wins in the operating port 33, the first symbol display device 41 displays the first symbol in a variable manner, and when the confirmed symbol after the stop becomes a combination of specific symbols set in advance, a big hit is given. appear. The variable winning device 32 is configured to be in a predetermined open state so that the game ball can easily win. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, it is assumed that the condition for shifting to a round is satisfied, and the variable prize-winning device 32 is repeatedly opened up to a maximum of a plurality of rounds (for example, 15 rounds).

  The game board 30 is provided with a rail unit 50 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. The launched game ball is guided to a predetermined game area through the rail unit 50. The rail unit 50 is formed of a resin molded product having a ring shape, and more specifically, a fluorine-containing polycarbonate resin is used to reduce frictional resistance. The rail unit 50 includes an inner rail portion 51 and an outer rail portion 52 that are provided in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about 1/4 of the upper portion, and the outer rail portion 52 surrounds the upper open area of the inner rail portion 51 and is parallel to the left side portion of the inner rail 51. Are formed in a substantially semi-annular shape.

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

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

  An arc-shaped flange 56 projecting outward is formed on the outer periphery of the rail unit 50. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into the plurality of through holes formed in the flange 56 and the game board 30. The rail unit 50 is fastened to 30. Here, the upper and lower and left and right ends of the rail unit 50 are formed in a substantially linear shape. That is, the flanges 56 are cut off at the upper and lower and left and right ends of the rail unit 50 so that the rail diameter can be expanded in a finite area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. It has become. The rail unit 50 is disposed so that the position of the gaming area on the gaming board 30 that is the maximum width reaches the left and right end positions of the gaming board 30. Among the parts corresponding to the ball guide passages of the rail unit 50, particularly with respect to the game ball receiving part, the corresponding flange 56 is provided from others in order to firmly attach the rail unit 50 and stabilize the flight of the game ball. There are also many screws (three in this embodiment, two in the other).

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

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

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

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. It demonstrates as an area | region remove | excluding. That is, since the game area does not include the ball guide passage portion, the left limit position toward the game area is specified by the inner rail portion 51 instead of the outer rail portion 52. Further, the right limit position toward the game area is specified by the inner rail portion 51, the lower limit position of the game area is specified by the lower end position of the game board 30 in which the out port 36 is formed, and the upper limit position of the game area. Is specified by the outer rail portion 52. Therefore, in the present embodiment, the width of the 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 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. That is, the width dimension of the game area is preferably as large as possible from the viewpoint of game area expansion. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more or 480 mm or more. In other words, the height of the game area is preferably as large as possible from the viewpoint of game area expansion. In addition, about the combination of the said width | variety and height, it can be set as what combined the said numerical value arbitrarily. If the width or height of the game area exceeds a certain value, a part of the game area may exceed the board surface of the game board 30, but other members may be placed along the game board surface in the area beyond the game area. What is necessary is just to supplement by providing.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is 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 related art, so that the game board 30 having the same size as the conventional one is used as in the present embodiment. So, it can be said that the game area is considerably expanded. It should be noted that the outer 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 has to be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more. In order to secure 80% or more, it is difficult to make the shape of the game area into a substantially circular shape. Therefore, it is preferable to have a shape in which the corner (for example, the lower right corner or the upper right corner) is expanded. .

  Further, the ratio of the area of the game area to the area of the front side of the entire pachinko machine 10 is about 40%, which is a much larger area ratio than in the past. The area ratio of the game area to the area 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 connection with the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable prize-winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided in the center of the game area, the through-gate 34, the windmill 37, and a plurality of nails are provided on the left and right sides of the variable display unit 35. (Guide nails such as a triangular nail for guiding the game ball to the center) and other objects can be provided with a margin, and the flow of the game ball in the game areas on the left and right sides of the variable display unit 35 It is not monotonous and you can fully enjoy the behavior of the game ball.

  Notches 38 are formed on both the left and right sides of the game board 30 to avoid interference with the protruding areas from the left and right sides of the main body frame 12, and the maximum width of the game area on the game board 30 in the rail unit 50 It has already been described that the position reaches the left and right end positions of the game board 30, but as will be described later, reinforcing members (bearing brackets 235: FIG. 9) provided on the left and right side portions of the main body frame 12. The game board 30 is attached to the main body frame 12 so as to have a width that leaves an area for arranging the locking device (the base frame 247, the interlocking rod 248, etc .: see FIG. 9). For these reasons, the game area is being expanded.

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

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

  When the foul balls flow backward in the ball guide passage, most of them flow along the outer rail portion 52 and fall downward when reaching the lower end portion of the outer rail portion 52. Some rampage in the ball guide passage and jump to the inner rail 51 side. At this time, the splashed foul ball hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 76. Thereby, all of the foul balls are reliably guided to the foul ball passage 76, and interference between the foul balls and the game balls to be fired next is suppressed.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front door frame 13 side (ball outlet leading from the most downstream portion of the upper plate 23). At this time, since the launch position of the game ball is lowered in this embodiment, the drop from the exit of the ball on the front door frame 13 side to the launch position becomes large, Guide members 63 and 64 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front door frame 13 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device is provided with a ball striking rod that is supported so as to be rotatable about the base end portion, and a game ball is launched along with the rotation of the ball striking ball. It is rare. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to a light metal such as aluminum and reducing the size of the hitting shaft, the head portion of the hitting ball (opposite to the base end) is required to ensure sufficient firing force. A weight is provided at the tip of the side. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, the hitting ball can be easily picked or hooked, and the effect of facilitating adjustment of the hitting strength of the hitting tip can be obtained.

  In addition, a pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 10) provided on the back surface of the main body frame 12, and game balls are basically discharged from the first discharge port 66. When the passage leading to the upper plate 23 including the first outlet 66 is filled with game balls, the game balls are discharged from the second outlet 67 instead of the first outlet 66.

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

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

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

  A small window 79 is also provided in the resin base 25 at the upper left portion of the window hole 26. The small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is closed with respect to the main body frame 12, the pin is pushed in and the front door frame 13 is closed. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 5) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached for conducting the metal fittings to the main body frame 12 side and grounding them. Therefore, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

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

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

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

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 5 is a rear view of the front door frame 13.

  The front door frame 13 is formed with a window portion 101 as a viewing window so that almost the entire game area can be viewed from the front. The window portion 101 has a substantially oval shape that is nearly circular, and more specifically, a substantially central portion on the left and right sides of the window portion 101 is gently curved as compared to the upper and lower sides. The substantially central portion may have a linear shape. Above the window part 101 of the front door frame 13, the frame width of the narrowest part is about 61 mm. The frame width dimension in the present embodiment is substantially the same as the distance between the uppermost part of the outer rail portion 52 (the upper end of the game area) and the upper end of the main body frame 12 in the main body frame 12, and is 85 mm to This is significantly shorter than the conventional model having the frame width of about 95 mm. Thereby, the visibility of the upper area in the game area can be easily ensured, and the large variable display unit 35 can also be arranged relatively upward. The dimension of the frame width (narrowest part) above the window 101 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be secured, the thickness may be 50 mm or less.

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

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

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

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and confirmation of the card frequency can be performed by the ball lending operation unit 120 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. it can. That is, the ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is paid out as long as there is a remaining amount on the card or the like. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. In addition, in a pachinko machine (so-called cash machine) in which game balls are rented directly from a ball lending device or the like to a top plate without using a card unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is attached to 120 installation portions. Thereby, in the configuration of the pachinko machine 10 provided with the ball rental operation unit 120, the pachinko machine using a card unit (so-called CR machine) and the cash machine can be shared.

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 5, reinforcement plates 131, 132, 133, and 134 are respectively attached to the back side of the front door frame 13 and on the left and right and upper and lower outer sides of the window portion 101. These reinforcing plates 131 to 134 are connected in contact with each other, but resin parts 135 for avoiding direct contact are interposed at the connecting portions of the left and upper reinforcing plates 132 and 133 in the drawing. Thereby, the closed loop of the electric path by the reinforcing plates 131 to 134 is cut, and the generation of a magnetic field causing noise is prevented.

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

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

  A resin case 136 is attached to the lower reinforcing plate 134 at a position facing the firing rail 61. The resin case 136 accommodates a circuit board for the ball rental operation unit 120. The back surface of the resin case 136 (the surface visible in FIG. 5) is flat, and constitutes the side wall of the firing rail 61 when the front door frame 13 is closed. Therefore, the game ball is prevented from spilling forward from the launch rail 61.

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

  The reinforcing plates 131 to 134 described above also have a function as a metal frame for supporting the glass, and the inside of these reinforcing plates 131 to 134 is folded back to form a glass holding groove. 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, the pachinko machine 10 according to the present embodiment is designed to expand the game area. Therefore, when the front door frame 13 is closed, the ball guide formed between the inner and outer rail portions 51 and 52 is used. A part of the passage is covered with the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of getting caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers the section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 5 where the rail cover 140 is attached to the front door frame 13), the portion where the ball guide passage protrudes from the side edge portion of the glass 137 A covering portion 141 for covering the surface is provided. With the above-described configuration of the rail cover 140, when the front door frame 13 is closed, the back surface of the rail cover 140 covers almost the entire area of the ball guide passage, so that the game ball jumps out of the ball guide passage. It is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

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

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

  First, an overall outline of the rear configuration of the pachinko machine 10 will be described. On the back side of the pachinko machine 10, various control devices (various control boards) are arranged so as to be arranged in the vertical and horizontal directions or stacked in front and back, and a game ball supply device for supplying game balls (Discharge mechanism), a protective cover made of resin, and the like are attached. In the present embodiment, various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. A device 312 (launch control board) and a power supply device 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201” and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are also integrated as one unit, and the resin portion is generally referred to as a back pack, this unit is referred to as a “back pack unit 203” herein. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units, and are provided with a support shaft part in a part to form the main body frame 12. Or it has the composition which can be developed to the back of game board 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 8, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Yes. Further, the back pack unit 203 is disposed in a region partially overlapping with the first control board unit 201.

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

  The support shafts M1, M4, and M6 that rotatably support the units 201 to 203 have a hinge structure that can be easily removed while the units 201 to 203 are opened from the back surface of the pachinko machine 10. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3, rotating the unit 201 around the axis A, and expanding the unit 201. Lift in condition. Thereby, if there is no back pack unit 203, the first control board unit 201 can be removed. Further, with respect to the second control board unit 202, the fastening of the fastening portion M5 is released, the unit 202 is rotated about the axis B, is unfolded, and is lifted in that state. Thereby, the 2nd control board unit 202 can be removed. Further, with respect to the back pack unit 203, the fastening portion M7 and the locking portions M8 and M9 are unlocked, and the unit 203 is unfolded by rotating around the axis C and lifted in that state. Thereby, the back pack unit 203 can be removed.

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

  Next, the back surface structure of the main body frame 12 and the game board 30 is demonstrated. 9 is a rear view showing a configuration in which the game board 30 is assembled to the main body frame 12 and the units 201 to 203 are removed, and FIG. 10 is a perspective view of the main body frame 12 as viewed from the rear. FIG. 11 is a perspective view of the game board 30 as viewed from the rear.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 25 from the back side, and a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the main body frame 12. It is fixed so as not to fall backward. The locking fixtures 211 and 212 can be manually rotated, and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a locked state. The left and right three locking fixtures 211 are L-shaped fittings formed by bending metal pieces, and are configured not to protrude outward from the main body frame 12 when the game board 30 is fixed.

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

  The backup area 503a stores values such as a stack pointer, each register, I / O, etc. when the power is shut down (including when a power failure occurs, the same applies hereinafter) when the power is shut off due to the occurrence of a power failure or the like. The area of the pachinko machine 10 can be restored to the state before the power cut-off based on the information in the backup area 503a when the power is turned on (including power-on due to power failure cancellation). Yes. Writing to the backup area 503a is executed when the power is shut off by the NMI interrupt process (see FIG. 35), and restoration of each value written to the backup area 503a is executed in the main process (see FIG. 28) when the power is turned on. Note that the power failure signal SG1 from the power failure monitoring circuit 542 is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 501 when the power is interrupted due to the occurrence of a power failure or the like. The NMI interrupt process as a process is immediately executed.

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

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

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

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

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

  The launch control device 312 permits or prohibits the launch of the game ball by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. Specifically, the launch control signal is output from the payout control device 311, the player is detecting that the player is touching the game ball launch handle 18, and the launch for stopping the launch. On condition that the stop switch is not operated, the launch motor 229 is driven, and the game ball is launched with a strength corresponding to the operation amount of the game ball launch handle 18.

  Based on the symbol display command transmitted from the main controller 271, the display control device 214 displays the variation of the first symbol (special symbol) in the first symbol display device 41 and the second symbol in the second symbol display device 42 ( This is to control the variation display of normal symbols. However, the configuration related to the display control of the first symbol of the display control device 214 will be described later. In addition, the display control device 214 transmits a control command to the sound lamp control device 272, and the sound lamp control device 272 controls various lamps and speakers according to the control command received from the display control device 214.

  The power supply device 313 includes a power supply unit 541 for supplying power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 for monitoring power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And. The power supply unit 541 supplies necessary operating power to the main control device 271 and the payout control device 311 through a power supply path (not shown). As its outline, the power supply unit 541 takes in an AC 24 volt power supply supplied from the outside, and generates a + 12V power supply for driving various switches and motors, a + 5V power supply for logic, a backup power supply for RAM backup, and the like. Then, these + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 271 and the payout control device 311. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the CPU 501 of the main control device 271 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541. When this voltage becomes less than 22 volts, it is determined that a power failure (power shutdown) occurs. The power failure signal SG1 is output to the main controller 271 and the payout controller 311. Based on the output of the power failure signal SG1, the main control device 271 and the payout control device 311 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 541 outputs the output of 5 volts, which is the drive voltage of the control system, to a normal value for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain. Therefore, the main control device 271 and the payout control device 311 can normally execute and complete the NMI interrupt processing.

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

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

  As shown in FIG. 24, the display control device 214 includes a CPU 521, a program ROM 522, a work RAM 523, a video display processor (VDP) 524, a video RAM 525, a character ROM 526, and an input port 527. The CPU 521 of the display control device 214 receives the symbol display command (stop symbol command, variation pattern command, confirmation command, etc.) transmitted from the main control device 271 via the input port 527 and analyzes the received command or Based on the received command, predetermined arithmetic processing is performed to control the VDP 524 (specifically, generation of an internal command for the VDP 524). The program ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and also stores and holds JPEG format image data for background images. The work RAM 523 is a memory for temporarily storing work data, flags, and the like used when the CPU 521 executes various programs.

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

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

  Here, the 1st symbol displayed on the 1st symbol display apparatus 41 and the display content on the display screen in the 1st symbol display apparatus 41 are demonstrated based on FIG. 25, FIG. FIG. 25 is a drawing individually showing a plurality of symbols as the first symbol. FIG. 26 is a diagram showing the display screen G of the first symbol display device 41, in which (a) shows the area division setting and effective line setting in the display screen G, and (b) shows the actual symbols. Indicates the display contents.

  As shown in (a) to (l) of FIG. 25, the first symbol is composed of 10 types of main symbols with numbers “1” to “9” and two types of musical symbols. It consists of sub-designs. Specifically, in each main symbol, numbers “1” to “9” are attached to the right side of the rear symbol composed of nine types of cat characters to which different characteristics are given. However, there are two main symbols to which the number “4” is attached, and the main symbol is the same as the cat character that is the rear symbol, but the color of the number to which it is attached is different. Further, the differences in the characteristics of the nine types of cat characters are provided not only by the colors assigned to the cat characters but also by the outer shape (contour), the size of the eyes, and the shape. In this case, the main symbols with odd numbers (1, 3, 5, 7, 9) correspond to “high probability symbols”, and when the high probability symbols are aligned, the big game state that is a special gaming state is entered. After that, the state shifts to a state with a high probability. The main symbols with even numbers (2, 4, 6, 8) correspond to “low-probability symbols”, and when the low-probability symbols are aligned, the game shifts to a jackpot state. Does not transition to the time state. The high probability means a state in which the combination of the first symbol becomes a big hit by a predetermined combination of probability fluctuation symbols, and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state. On the other hand, the sub-symbol consists of a symbol represented by only one simple note and a symbol obtained by connecting two simple notes together.

  Next, the display screen G of the first symbol display device 41 will be described. As shown in FIG. 26 (a), the display screen G of the first symbol display device 41 is set with three symbol rows Z1, Z2, and Z3 of upper, middle, and lower, and each symbol row Z1 to Z3. In addition, the above-described first symbols are displayed in a prescribed order. Specifically, in the symbol row Z1, nine kinds of main symbols “1” to “9” are arranged in descending order of numbers, and two types of sub-designs are alternately arranged between the main symbols. . In the symbol row Z3, nine kinds of main symbols “1” to “9” are arranged in ascending order of numbers, and two types of sub-designs are alternately arranged one by one between the main symbols. On the other hand, in the symbol row Z2, nine types of main symbols “1” to “9” are arranged in ascending order of numbers, and further between the main symbol “9” and the main symbol “1”. The main symbol “4” is arranged in the box. That is, only the symbol row Z2 has two main symbols “4” arranged, and there are ten main symbols. Note that, as described above, the main symbol of “4” arranged in two has the same type of cat character as the rear symbol, but the color of the number attached is different, so that the main symbol of “3” Identify whether the symbol is “4” main symbol between the symbol and “5” main symbol or “4” main symbol between “9” main symbol and “1” main symbol It is possible. Further, the sub symbols arranged in the symbol row Z2 are alternately arranged one by one between the main symbols, like the symbol rows Z1 and Z3. On the display screen G, the plurality of first symbols arranged in the symbol rows Z1 to Z3 are displayed in a variable manner so as to scroll from right to left with periodicity. In addition, on the display screen G, the first symbols are displayed in the left, middle and right columns in each of the symbol columns Z1 to Z3, and as a result, a total of nine first symbols of 3 columns × 3 columns are displayed. It is like that. Actually, as shown in FIG. 26B, a total of nine main symbols and sub-designs of the first symbol are displayed on the display screen G.

  On the display screen G, five effective lines, that is, a left line L1, a middle line L2, a right line L3, a left rising line L4, and a right rising line L5 are set. In each game, the variable display of the first symbol is stopped in the order of the upper symbol row Z1 → the lower symbol row Z3 → the middle symbol row Z2, and when the symbol is fixed, the first symbol is a big hit on any active line. If a combination of symbols (in this embodiment, the same combination of main symbols) is arranged, a jackpot moving image is displayed as a jackpot. When the change display of the first symbol of the upper symbol row Z1 and the lower symbol row Z3 is stopped, the combination of the same main symbols is stopped on one of the effective lines, and in this state, the middle symbol row Z2 A state in which one symbol is displayed is a reach variation state, and a jackpot is basically generated through this reach variation state.

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

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information during the game to perform jackpot lottery, setting the symbol display of the first symbol display device 41, and the like. Specifically, As shown in FIG. 27, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 41, and the first symbol display device 41 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, , Upper, middle and lower out symbol counters CT, CM, CB used to set each out symbol in the upper row, middle row and lower row It is set to be there.

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

For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. 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 periodically (in this embodiment, 1 per timer interrupt).
Times) and is stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means a state in which the combination of the first symbol is a big hit by a predetermined combination of probability fluctuation symbols and the subsequent jackpot probability is increased as added value, that is, a so-called probability change, and is normal (low) (When probability) means the time when it is not such a probable state.

  The jackpot symbol counter C2 determines the symbol when the fluctuation of the first symbol display device 41 is stopped in the case of a jackpot. In the present embodiment, the first symbol display device 41 has five effective lines. Since ten specific symbols (main symbols) are set, 50 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the 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 first symbol display device 41, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. The other variation type counter CS2 is, for example, incremented by 1 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 whether or not to generate a reach expectation effect to be described later, so-called normal reach, super reach, premium reach, etc., the reach type of the first symbol, and other rough symbol variation modes. The type counter CS2 determines a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the final stop symbol (in this embodiment, the middle symbol) stops after the reach occurs. Accordingly, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by the combination of the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the first symbol display device 41 starts the variation of the first symbol.

  The upper, middle, and lower out symbol counters CT, CM, and CB are used to determine the outage stop symbol of the first symbol in the upper row, the first symbol in the middle row, and the first symbol in the lower row when the big hit lottery is lost. Is. In the upper row 1 symbol and the lower row 1 symbol, any one of 18 first symbols including the main symbol and the sub symbol is displayed, so 18 counter values (0 to 17) are prepared for each. Has been. On the other hand, in the first symbol in the middle row, any one of the 20 first symbols is displayed including the main symbol and the sub symbol, so 20 counter values (0 to 19) are prepared. Left symbol, middle symbol, right symbol in the upper symbol row is determined by the off symbol counter CT, left symbol, middle symbol, right symbol in the middle symbol column is determined by the symbol symbol counter CM, and the lower symbol column is determined by the symbol symbol counter CB. The left, middle and right symbols are determined.

  In this embodiment, the value of each counter CT, CM, CB is updated at random by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CT, CM, CB is updated, the lower 3 bits of the R register are added to the previous value, and if the addition result exceeds the maximum value, the up / down / outlier symbol counter In this case, 18 is subtracted, and in the case of the out / out symbol counter, 20 is subtracted to determine the current value. Each outlier symbol counter CT, CM, CB is updated within the normal processing so that the update times do not overlap, and the combination of these outlier symbol counters CT, CM, CB is the reach of the RAM 503 out of front / rear out symbol buffer, reach other than out of front / back out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the time of starting the variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier and the complete out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

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

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

  FIG. 33 is a flowchart showing the timer interrupt process, and this process is executed by the CPU 501 of the main controller 271 every 2 msec, for example.

  In FIG. 33, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 271 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

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

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. This start winning process will be described with reference to the flowchart of FIG. 34. In step S701, whether or not the game ball has won the start opening 33 (start winning prize) is determined based on the detection information of the operation opening switch 224. If it is determined that the game ball has won the operation port 33, in the subsequent step S702, it is determined whether or not the number N of operation reservation balls of the first symbol display device 41 is less than the upper limit value (4 in the present embodiment). Determine. The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In the subsequent step S704, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in the step S603 are stored in the first free area of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

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

  FIG. 35 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 35 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within the predetermined time.

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

  The above NMI interrupt processing is executed in the same manner in the payout control device 311, and the state of the payout control device 311 when the power is shut down due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513 by the NMI interrupt. Similarly, power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout controller 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 35 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 28 is a flowchart showing an example of a main process executed by the CPU 501 in the main control device 271, and this main process is started upon a reset when the power is turned on.

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

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

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in a hall, the power is turned on while pressing the RAM erase switch 323. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to a RAM initialization process (steps S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to the initialization process of the RAM 503 (steps S114 to S116). . 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, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S108, the stack pointer before power-off is restored, and in step S109, information on occurrence of power-off is cleared. In step S110, a command for returning the sub-side control device to the gaming state at the time of power-off is transmitted, and in step S111, the used register is returned from the backup area 503a of the RAM 503. In steps S112 and S113, the interrupt permission / non-permission is returned to the state before the power shutdown, and then the address before the power shutdown is returned.

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

  In the normal process, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, when the first symbol display device 41 displays the variation of the first symbol, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 214. In addition, after the start of the fluctuation of the first symbol, one each time in the normal process in the order of the fluctuation pattern command → stop symbol command of the upper symbol row → stop symbol command of the middle symbol row → stop symbol command of the lower symbol row The command is transmitted once every 4 msec), and the confirmation command is transmitted at the timing when the fluctuation time elapses.

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

  The update process of each outlier symbol counter CT, CM, CB will be described. As shown in FIG. 30, in step S301, it is determined whether or not it is time to update the outlier symbol counter CT in the upper symbol row. It is determined whether or not it is time to update the symbol counter CM that is out of the symbol row. If it is the time to update the upper symbol sequence (YES in step S301), the process proceeds to step S303, and the out symbol symbol CT of the upper symbol sequence 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. Furthermore, if the lower symbol row is updated (both steps S301 and S302 are NO), the process proceeds to step S305, and the lower symbol row outlier symbol counter CB is updated. In updating the outlier symbol counters CT, CM, and CB in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and when the addition result exceeds the maximum value, 20 is subtracted, The calculation result is out of sync and is used as the current value of the symbol counters CT, CM, and CB. According to the above CT, CM, and CB update processing, the off symbol counters CT, CM, and CB of the upper symbol row, the middle symbol row, and the lower symbol row 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 CT, CM, and CB is updated.

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

  After update processing of the off symbol counters CT, CM, and CB, in step S204 in FIG. 29, a prize ball counting signal and a payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed. By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

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

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

  Thereafter, in step S208, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 msec in the present embodiment) has elapsed since the start of the previous normal process. Then, the random number initial value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S209 and S210). That is, in step S209, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in the present embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In step S210, update of the variation type counters CS1 and CS2 is executed. Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS1 and CS2 are stored in the corresponding buffer area of the RAM 503.

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

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

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

  If neither the big hit or the change in the first symbol is being displayed and if the number N of activated balls is> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of active suspension balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process 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, the first symbol variation start process is executed. Here, the details of the variation start process will be described with reference to the flowchart of FIG. 32. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. “601, 661” is the winning value.

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

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

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

  If the front / rear outreach has occurred, the process proceeds to step S506, and the values of the upper, middle, and lower outreach counters CT, CM, and CB stored in the front / rear outreach symbol buffer of the RAM 503 are set as stop symbol commands. Also, in step S507, a variation pattern for front / rear out of reach display is determined, and the variation pattern is set as a variation pattern command. At this time, as in step S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503 are checked, and the reach such as normal reach and super reach is determined based on the value of the first variation type counter CS1. The type and other rough symbol variation modes are determined, and an 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, A more detailed symbol variation mode such as the number of variation symbols) is determined.

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

  If it is neither a big hit nor a reach, the process proceeds to step S510, and the respective values of the upper, middle, and lower off symbol counters CT, CM, and CB stored in the complete off symbol buffer of the RAM 503 are set in the stop symbol command. In step S511, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like. As described above, when setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, at the time of reach, or at the time of no reach, the reach expectation effect determination process for determining whether or not to perform the reach expectation effect described later is performed. Done. Specifically, when a big hit or a reach occurs, the process proceeds to S512, and a reach expectation effect determination process based on the high probability table is performed. On the other hand, when the reach is not generated, the process proceeds to S513, and the reach expectation effect determination process based on the low probability table is performed. And after performing these reach | attainment production | presentation determination processes, this process is complete | finished. The reach expectation effect determination process will be described in detail later.

  Returning to the description of FIG. 31, when step S402 is YES, that is, when the first symbol variation display is in progress, the routine proceeds to step S407, where it is determined whether or not the variation time has elapsed. At this time, the variation time of the first symbol is determined according to the variation pattern of the first symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a confirmation command set for confirming the stop symbol is set, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 36 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

  First, in step S901, an initial setting process associated with power-on is executed. Specifically, a predetermined value 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 271 is received. When the payout permission command is received, the process advances to step S903 to permit RAM access, and in step S904, an external interrupt vector is set.

  Thereafter, 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, and in subsequent step S906, it is determined whether or not the information on occurrence of power shutdown is set in the backup area 513a of the RAM 513. To do. In step S907, a RAM determination value is calculated. In subsequent step S908, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the backup. The RAM determination value is, 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 has been pressed, the process proceeds to a RAM initialization process (steps S915 to S918). Similarly, when the occurrence information of the power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to the initialization process of the RAM 513 (steps S915 to S918). . That is, in step S915, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S916, initialization processing of the RAM 513 is executed. In step S917, the CPU peripheral device is initialized, and in step S918, interrupt permission is set, and the process proceeds to a payout control process described later.

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S909, the stack pointer prior to power shutdown is restored, and in step S910, the information on occurrence of power shutdown is cleared. In step S911, the CPU peripheral device is initialized, and in step S912, the used register is restored from the backup area 513a of the RAM 513. Further, in steps S913 and S914, the 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. 37, in step S1001, a command from the main controller 271 is acquired and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 16. That is, when the lower pan 16 is 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 is full, , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch. Perform configuration.

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

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

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

  In step S1013, the 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. 38, in step S1101, the payout motor 358a is driven to execute 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 of FIG.

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

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, a stop process 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. 39, in step S1201, the payout motor 358a is driven to pay out the lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process in FIG.

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

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

  Next, a specific procedure of display control by the display control device 214 will be outlined. FIG. 40 is a flowchart showing display control processing executed by the CPU 521 in the display control device 214. The CPU 521 executes display control of the first symbol display device 41 while processing various commands provided from the main control device 271 according to the procedure shown in FIG.

  In FIG. 40, first, in step S1301, it is determined whether a display command has been received from the main controller 271 or not. When step S1301 is NO, it waits until it receives some command. When the display command is received, the process proceeds to step S1302, and the contents of the display command are stored in the work RAM 523. In step S1303, various arithmetic processes such as generating an internal command for the VDP 524 are started based on the information stored in the work RAM 523. The internal command is a command for designating a series of display effects from the start to the end of the variable display, and a necessary internal command is generated each time based on information stored in the work RAM 523. As a result, the VDP 524 performs a drawing process in response to a command (internal command) from the CPU 521, and starts the variable display of symbols on the first symbol display device 41. At this time, the CPU 521 transmits a control command for operating a control command for driving voices and lamps to the voice lamp control device 272 in synchronization with the display effect at each time. As a result, the sound lamp control device 272 drives sounds and lamps according to the control command from the CPU 521. It should be noted that the symbol variation display is continued under the cooperation of the CPU 521 and the VDP 524 until the display command is received once until the confirmation command is received thereafter. Meanwhile, the CPU 521 performs the control of the VDP 524 and the command reception process shown in FIG. 40 in parallel. The control in the sound lamp control device 272 is the same.

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

  Here, in the present embodiment, a reach expectation effect may be performed in order to teach the degree of expectation for the occurrence of reach in a situation where the first symbols of all the symbol sequences Z1 to Z3 are variably displayed. This reach expectation effect occurs when it is determined that the effect is to be performed in the reach expectation effect determination process in S512 and S513 of FIG. This reach expectation effect determination process is performed by referring to the value of the first variation type counter CS1 based on a preset table. However, the above table has a high-probability table where a reach expectation effect will occur with a relatively high probability and a low-probability table where a reach expectation effect will occur with a relatively low probability. Alternatively, in the case of reach occurrence, reach expectation effect determination processing based on the high probability table is performed in S512, and in the case of no reach occurrence, reach expectation effect determination processing based on the low probability table is performed in S513. Specifically, in the high probability table, a number from 0 to 198 is set corresponding to the range of the value of the first variation type counter CS1, and the value of the first variation type counter CS1 is from 0 to 149. Is determined to perform the reach expectation effect, and when the value of the first variation type counter CS1 is 150 to 198, it is determined that the effect is not performed. In other words, in game times in which a jackpot or reach occurs, a reach expectation effect will occur with a probability of about 3/4. On the other hand, the low probability table, like the high probability table, is set with a number from 0 to 198. When the value of the first variation type counter CS1 is 0 to 20, the decision to perform the reach expectation effect is made. When the value of the first variation type counter CS1 is 21 to 198, it is determined that the effect is not performed. That is, in game times where no jackpot or reach occurs, the reach expectation effect occurs with a probability of about 1/10. Accordingly, the reach expectation effect determination process is performed at a higher probability when the jackpot occurs and when the reach occurs than when the reach does not occur. Note that the probability of occurrence of the reach expectation effect based on the high probability table and the low probability table may not be the above probability. For example, in the case of a high probability table, the above effect may be generated at 9/10, and in the case of a low probability table, the above effect may be generated at 1/20.

  If it is determined that the reach expectation effect is to be performed, the first symbol stop symbol command and the first symbol variation pattern command in the symbol variation display process in step S1303 of FIG. By referring to the display command including “”, the type of cat character performing the reach expectation effect is selected. Specifically, when a jackpot occurs in the game time, a cat character corresponding to the main symbol that is the jackpot is selected, and when a reach occurs in the game time, the main symbol that is the reach. The cat character corresponding to is selected. When a double reach that does not result in a big hit occurs in the game times, the cat character corresponding to the main symbol that will be reached on the left rising line L4 is selected, but on the right rising line L5. The configuration may be such that a cat character corresponding to the main symbol to be reached is selected, or may be a configuration in which one is selected by lottery. When no reach occurs in the game times, a cat character corresponding to one of the main symbols stopped and displayed in the symbol row Z1 and the symbol row Z3 is selected. However, if the same type of combination exists in the main symbols stopped and displayed in the symbol row Z1 and the symbol row Z3, the cat character corresponding to the main symbol is selected. After the selection of the cat character, the variation mode of the reach expectation effect is determined. Thereby, the reach expectation effect by the combination of the selected type of cat character is performed.

  Next, the display mode of the reach expectation effect will be described below with reference to FIGS. 41 and 42. However, in FIG.41 and FIG.42, the display of a background screen is abbreviate | omitted and also the mode of the scroll fluctuation | variation of a 1st symbol is shown by the arrow. In the following description, for the sake of convenience, the above-mentioned main symbols will be described by numerical numbers assigned to them. Specifically, “1” symbol, “2” symbol, “3” symbol,. 9 ”Describe as a symbol. Further, when the main symbols once stopped in the upper and lower symbol rows Z1 and Z3 are the same, a line connecting the upper symbol and the lower symbol is described as a reach line. Further, as necessary, the terms such as the display screen G and the symbol rows Z1 to Z3 described in FIG. 26 are used.

  As shown in FIG. 41 (a), in a situation where the first symbols of all the symbol rows Z1 to Z3 are scroll-fluctuated, two identical cat characters appear as if the display screen G from the upper side of the display screen G. It appears as if it jumped out near the center. This set of cat characters has the same form as the cat character that constitutes the rear symbol of one of the main symbols (in this embodiment, “1” symbol). Further, in order to improve the visibility of a set of cat characters, the cat character is displayed slightly larger than the main symbols of the symbol rows Z1 to Z3, and the first symbol of the symbol rows Z1 to Z3 is further translucently processed. Is given. In addition, the cat characters constituting the main symbol corresponding to one set of cat characters are not displayed on the symbol row Z1 and the symbol row Z3, and only the numeric symbol is scroll-fluctuated for the main symbol. Thereby, it is possible to make the player intuition that the cat character that has been scroll-fluctuated on the symbol row Z1 and the symbol row Z3 jumps out of the symbol row Z1 and the symbol row Z3 and produces an effect.

  After that, as shown in FIG. 41 (b), a set of cat characters are displayed in a variable manner as if they were playing, without being restricted by the symbol rows Z1 to Z3 and the effective lines L1 to L5. The Even in this situation, the first symbols in the symbol rows Z1 to Z3 are scrolled while maintaining the above-described state. Then, after the endlessly variable display of a set of cat characters is performed for a predetermined time, as shown in FIG. 42 (a), on one effective line (right line L3 in the present embodiment) One cat character is moved and displayed on the symbol row Z1 and the symbol row Z3, and stopped at the corresponding position. Even in this situation, the first symbols in the symbol rows Z1 to Z3 are scrolled while maintaining the above-described state.

  After that, at the timing when the cat symbol in the symbol row Z1 is erased and the main symbol which is only the numerical symbol arrives at the position of the cat character stopped and displayed on the upper stage (on the symbol row Z1) on the active line, The first symbol of the symbol row Z1 is stopped and displayed. Then, the cat character positioned on the upper stage on the active line is reduced and displayed so as to have the same size as the main symbols in the symbol rows Z1 to Z3, and further, the state of the original main symbol, that is, the cat character and the number symbol Are displayed in a combined state. After that, the cat character in the symbol row Z3 is erased at the position of the cat character stopped and displayed in the lower row (on the symbol row Z3) on the valid line, as in the case of the upper portion on the valid line, and only the numeric symbol is displayed. The first symbol of the symbol row Z3 is stopped and displayed at the timing when the main symbol is reached. Then, the cat character located at the lower stage on the active line is displayed in a reduced size so as to have the same size as the main symbols of the symbol rows Z1 to Z3, and further, the state of the original main symbols, that is, the cat character and the number symbol Are displayed in a combined state. As a result, as shown in FIG. 42B, a reach line is formed by the main symbol corresponding to the cat character that has been variably displayed as an effect, and a reach variation state is established. At this time, the first symbol other than the main symbol on the reach line (in this embodiment, “2” symbol, “4” symbol, and sub-symbol) is still subjected to the translucent processing. Thereby, the reach line can be emphasized. Thereafter, when the first symbol of the symbol row Z2 is stopped and displayed, if the symbol that has reached the reach on the reach line is stopped and displayed, a big hit will occur.

  On the other hand, after a set of cat characters is variably displayed vertically and horizontally, each cat character may not be stopped and displayed on one effective line. For example, one cat character is stopped and displayed on the upper line on the middle line L2, and the other cat character is stopped and displayed on the lower line on the left line L1, or one cat character is stopped on the upper line on the middle line L2. In this case, the other cat character is displayed in a variable manner so as to escape from the display screen G so that it is not displayed on the display screen G. In this case, at the timing when the main symbol, which is only the number symbol and the cat character in the symbol row Z1 or the symbol row Z3 reaches the position of the cat character that is stopped and displayed, each symbol row Z1, The first symbol of Z3 is stopped and displayed. Then, the cat character that is stopped and displayed is reduced and displayed so as to have the same size as the main symbols of the symbol row Z1 to the symbol row Z3, and is further displayed in the state of the original main symbol. At this time, the translucency processing of the first symbol of the symbol rows Z1 to Z3 is canceled. In this case, since the reach line is not formed, when the first symbol of the middle symbol row Z2 is stopped and displayed, the game round is ended.

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

  In a situation where the first symbols of all the symbol rows Z1 to Z3 are scroll-fluctuated, it is possible to optimally draw out the player's sense of expectation for the occurrence of reach by adopting a configuration that achieves the reach expectation effect. Also, generally, the game situation until the upper symbol row Z1 and the lower symbol row Z3 are stopped and displayed is not so much noticed even in the game times where the reach occurs, and it is a time when the player is bored. Tend to. On the other hand, by performing the reach expectation effect, the player can be entertained even during the period until the upper symbol row Z1 and the lower symbol row Z3 are stopped and displayed, and the game entertainment can be improved. .

  In addition, by setting the reach expectation effect using a cat character that is one of the constituent symbols constituting the main symbol, it is taught which main symbol the reach occurs when a reach occurs thereafter. be able to. That is, by visually recognizing the reach expectation effect, the player can know in advance which of the main symbols the reach line will be formed when a reach occurs thereafter. In particular, when a reach expectation effect is performed by a cat character constituting a high-probability symbol, the player expects a jackpot due to the high-probability symbol, so the reach expectation effect is an effect that attracts a great deal of attention. Thus, with this configuration, the expectation level felt by the player can be changed depending on the type of cat character displayed in the reach expectation effect, so the reach expectation effect can be varied. As a result, it is possible to further enhance the interest by making the game more varied. Also, with this configuration, there are nine types of cat characters that perform the reach expectation effect, and thus the aspect of the effect can be diversified. Furthermore, with this configuration, it is not necessary to set a character or the like for performing the reach expectation effect, so that the reach expectation effect can be performed without substantially increasing the ROM capacity of the display control device 214.

  In addition, a reach expectation effect is performed using a cat character that is one of the constituent symbols constituting the main symbol, and when the effect ends, the cat character is stopped and displayed on the symbol rows Z1 and Z3. When the reach character is formed by changing the cat character to the corresponding main symbol, the game is performed when the reach expectation effect and the variation display of the first symbol in the symbol sequence Z1 to Z3 are correlated. Can be intuitive. Therefore, it is possible to visually recognize aspects such as reach fluctuation after the reach expectation effect as a series of flows without making the player feel uncomfortable. Moreover, when the reach expectation effect is performed, the above effect can be made more conspicuous by adopting a configuration in which the main symbol corresponding to the cat character is variably displayed with only the numeric symbol.

  Further, when the reach expectation effect is performed, the cat character is displayed in the symbol columns Z1 to Z3 by being displayed in a variable manner without being restricted by the symbol columns Z1 to Z3 and the effective lines L1 to L5. Since a clear difference can be provided between the variation display mode of the first symbol and the mode of reach expectation effect, the player can clearly recognize that the reach expectation effect is being performed and the mode of the effect. it can. Further, when the effect is being performed, the first symbol in the symbol row Z1 to Z3 is subjected to a translucency process, and the cat character is displayed larger than the main symbol in the symbol row Z1 to Z3. The above effects can be made more remarkable.

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

  (A) In the above embodiment, the reach expectation effect is performed by variably displaying two cat characters. However, three, four, five, or six or more cat characters are variably displayed. It is good also as a structure which performs reach expectation production by doing. For example, when four cat characters are variably displayed, two of the same type of cat character are variably displayed (for example, two are “1” symbols and two are “9”). Design). In this case, compared to the case where two cat characters are displayed, it is possible to make the player intuition that there is a chance of reach occurrence, and it is possible to increase the expectation for reach occurrence during the reach expectation effect. For example, the structure which determines by the lottery how many cat characters are displayed in a reach expectation effect may be sufficient. In this case, if the configuration is such that the more the number of cat characters is displayed, the higher the degree of expectation for the occurrence of reach or the occurrence of jackpot, the fun of reach expectation effect can be further improved.

  (B) In the above embodiment, the second design as the character that performs the reach expectation effect is a configuration set by one design constituting the main design. It is good also as a structure which sets the effect character which can associate the main symbol, and performs reach expectation effect using the said effect character. For example, a kitten character having the characteristics of each main symbol cat character may be set, and the reach expectation effect as in the above embodiment may be performed using the kitten character.

  (C) In the above embodiment, the display screen G has three symbol rows set, and the first symbol is variably displayed so as to scroll in the predetermined fluctuation direction along the symbol row. However, this may be changed. For example, a configuration may be adopted in which a display position of 3 rows and 3 columns is set on the display screen G, and a plurality of symbols are switched and displayed in a predetermined order at a total of nine display positions. Even in this case, the same effect as that of the above-described embodiment can be obtained if the reach expectation effect is configured as in the above-described embodiment.

  (D) In the above embodiment, when the reach expectation effect is being performed, the first symbol in the symbol sequence Z1 to Z3 is subjected to the translucent processing, and the cat character is displayed larger than the first symbol. However, this may be changed. For example, the first symbols in the symbol rows Z1 to Z3 may be configured to be displayed as usual without being subjected to the translucent process. For example, the 1st symbol in symbol row Z1-Z3 may be the composition on which only the outline is displayed. Further, for example, the cat character may be displayed in the same size as the first symbol. Even if it is the said structure, since the cat character is fluctuate-displayed in length and breadth without being controlled by the symbol sequence Z1-Z3 and the effective lines L1-L5, the variation display of the 1st symbol in the symbol sequence Z1-Z3 is carried out. A clear difference can be provided between the aspect of the above and the aspect of the reach expectation effect.

  (E) In the above embodiment, when the reach expectation effect is performed, the main character corresponding to the cat character in the symbol row Z1 and the symbol row Z3 is not displayed and only the numeric symbol is variably displayed. However, this may be changed. For example, the main symbols corresponding to the cat characters in the symbol row Z1 and the symbol row Z3 may be configured not to be displayed. Even in this case, the same effects as those of the above embodiment can be obtained. In addition, for example, the main symbols corresponding to the cat characters in the symbol row Z1 and the symbol row Z3 may be displayed in the same manner as in normal times.

  (F) In the above-described embodiment, the determination as to whether or not the reach expectation effect is to be performed is performed by the reach expectation effect determination process in steps S512 and S513 in FIG. 32, but this may be changed. For example, it may be configured to determine whether or not to perform the above-mentioned effects in step S503, step S507, step S509, and step S511 in FIG. Moreover, the structure which determines not the main control apparatus 271 but the display control apparatus 214 whether the said production | presentation is performed may be sufficient. In this case, the processing load on the main controller 271 can be reduced.

  (G) In the embodiment described above, the display controller 214 selects the type of cat character that performs the reach expectation effect. However, the main controller 271 may perform the selection. For example, the configuration may be such that the selection is performed in the reach expectation effect determination process in step S512 and step S513 in FIG. Even in this case, the same effects as those of the above embodiment can be obtained.

  (H) In the above embodiment, the main controller 271 is configured to determine a fine combination of stop symbols, a symbol variation pattern, and a reach effect in the symbol display device 41, but this may be changed. . For example, the main control device 271 may have a configuration in which the display control device 214 determines these without determining a fine combination of stop symbols, a symbol variation pattern, and a reach effect in the symbol display device 41. In this case, the main control device 271 gives a display command to the display control device 214 that includes information such as which one of the big hits in the probable change state, the big hit in the normal state, or no big hit occurrence occurs in the game times. It is set as the structure output to it. Then, the display control device 214 determines a fine combination of stop symbols, a symbol variation pattern, and a reach effect based on the display command from the main controller 271 and displays the symbol variation display within the range of the switching display time. To control. With this configuration, it is possible to further reduce the processing load of the main controller 271 while achieving the effects of the above-described embodiment. In the case of this configuration, it is preferable to provide a display unit that directly displays the result of the big hit lottery in the main controller 271.

  (I) In the above embodiment, the table for determining whether or not the reach expectation effect is to be performed is provided with two types of tables for high probability and low probability, but this may be changed. . For example, a configuration in which only one type of table for determining whether or not to perform the above-described effect may be set. In this case, the reach expectation effect is generated with the same probability regardless of whether or not the reach occurs in the game times. In addition, for example, three types of tables for determining whether or not to produce the above-mentioned effects are set, and the probability that the above-mentioned effects will occur when a big hit occurs, when an outreach occurs or when no reach occurs. The structure to change may be sufficient.

  (J) In the above embodiment, even if a reach expectation effect occurs, the reach may not occur. However, when the effect occurs, a reach always occurs. Good. In this case, the effect can be referred to as a reach occurrence sign effect rather than a reach expectation effect. As a result, the player expects a reach occurrence sign production to occur, so that it is possible to improve the game entertainment.

  (K) In the above embodiment, even if reach occurs after the reach expectation effect occurs, the jackpot may not occur. However, after the reach expectation effect occurs, In the case of occurrence, it may be configured that the jackpot is surely generated. In this case, during the reach expectation effect, the player expects more reach lines, and the player's attention to the reach expectation effect can be dramatically improved.

  (L) In order to diversify the aspect of the reach expectation effect, a new aspect may be added to the aspect of the reach expectation effect in the above embodiment. For example, after a cat character is variably displayed in vertical and horizontal directions, before the cat character is moved and displayed on the symbol rows Z1 and Z3, an item representing a cat jar or the like is displayed on any of the symbol rows Z1 and Z3. It is good also as a structure which displays a stop at a position. In this case, if the above items are displayed above and below the one active line, the cat character is moved and displayed at the position where the item is displayed, and the player is informed that reach may occur. It can be expected. Therefore, with this configuration, the aspect of the reach expectation effect can be diversified, and the reach expectation effect can be suppressed from becoming a monotonous effect.

  (M) It is good also as a structure which arrange | positions the display apparatus provided with the organic EL element so that the glass 137 attached to the front door frame 13 as a pair of front and back may occupy most. And it is good also as a structure which performs the reach expectation effect in the said embodiment in the said display apparatus. In this case, since the reach expectation effect can be displayed in the area larger than the display screen G of the first symbol display device 41, the reach expectation effect can be emphasized more than the above embodiment.

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

  (O) In the above-described embodiment, the pachinko machine 10 having a relatively large game area as compared with the prior art has been described. However, the present invention is not limited to this, and a game machine such as a pachinko machine having a game area, a window, or the like as in the past It can also be applied to.
