Description

  The present invention relates to a gaming machine.

  For example, a gaming machine such as a pachinko gaming machine is known that includes a picture display device that displays a plurality of pictures on a display screen. In such a gaming machine, for example, when a game ball passes through an operating port, a lottery is performed as to whether or not a special gaming state advantageous to a player such as a big hit state is generated, and a variation display of a pattern is started. The When a lottery is won, a special gaming state advantageous to the player, such as a big hit state, is generated on the condition that the pattern confirmed and displayed on the display screen is a combination of specific patterns. . Then, for example, a special winning opening is opened with the occurrence of the special gaming state.

  In more detail about the change display of the pattern, first, when the pattern starts to change, and when a predetermined number of patterns stop, it becomes a combination that can generate a special gaming state, when the reach effect occurs, and when all the patterns stop A general flow is that a special gaming state occurs if a combination of specific patterns is used. For this reason, in recent years, a gaming machine has been proposed that has a plurality of types of reach productions to increase the expectation of occurrence of a special gaming state, and the degree of expectation for occurrence of a special gaming state differs for each reach production (for example, Patent Document 1).

  However, in the case where a reach effect having different degrees of expectation for occurrence of a special game state is provided, it is possible to predict to some extent whether or not a special game state is generated by the generated reach effect. As a result, there is a problem that the player may have a passive impression that the display status of the picture display device is forcibly shown in spite of being able to predict whether or not a special gaming state will occur. Also, because the process leading to the occurrence of a special gaming state is a uniform flow of starting the pattern variation, reaching production, and stopping with a specific pattern combination, it cannot wipe out that the basic progression of the game is monotonous. There is also a problem.

The above problems are not limited to pachinko machines, and a special gaming state occurs when one of the conditions is that a plurality of patterns are variably displayed on the display screen and the stopped pattern is a combination of specific patterns. This problem also applies to other gaming machines.

The front plate 14 is exposed on the front side of the pachinko machine 10, but by molding with ABS resin, it is possible to apply plating to appropriate portions of the surface for the purpose of decoration or the like. In addition, since the ashtray 21 is disposed in the vicinity, the portion constituting the lower plate 16 and the back wall panel 17 is made of flame-retardant ABS resin, so that it is difficult to burn even if cigarettes are accidentally placed. It is preferable to configure as described above.

  A front door frame 13 as a front door is provided in a range excluding the front plate 14 on the front side of the main body frame 12 so as to cover the main body frame 12. Accordingly, the entire front side of the main body frame 12 is covered by the front plate 14 and the front door frame 13. The front door frame 13 is attached to the main body frame 12 so as to be openable and closable. Like the main body frame 12, the front door frame 13 can be opened forward with an opening / closing axis extending vertically to the left when viewed from the front of the pachinko machine 10. It is like that. The front door frame 13 is formed of ABS resin, like the front plate 14. The front door frame 14 is exposed on the front side of the pachinko machine 10, but by molding it with ABS resin, it is possible to plate an appropriate portion of the surface for the purpose of decoration or the like.

  A lower portion of the front door frame 13 is provided with a bulging portion 22 that bulges to the near side above the lower plate 16, and an upper plate 23 that opens upward is provided inside the bulging portion 22. .

  In the pachinko machine 10, a glass door frame and a front decoration frame are individually provided, and these can be opened and closed with respect to the front frame (corresponding to the main body frame of the present embodiment), and an upper plate is provided on the front decoration frame. Unlike the conventional configuration, the glass door frame and the front decoration frame are integrated into a front door frame 13, and the upper plate 23 is provided integrally with the front door frame 13. 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 the present pachinko machine 10, for the purpose of extending 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 secured 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 distance in the vertical direction from the tip of the nozzle of the ball lending device arranged side by side on the left side of the pachinko machine 10 in the game hall becomes large, and there is a concern that the lending of the lending ball will be lost. 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 | hung the position of the upper plate 23, inconveniences, such as spilling of a rental ball, are eliminated. The height dimension of the rising portion 22a may be anything that matches the lowered dimension of the upper plate 23, and the maximum height dimension 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 bulge greatly toward the front side, but other portions above the upper plate 23 (annular electric decoration portion 102 and the like to be described later) ) 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, and 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 rectangular 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. Further, through gates 34 are arranged on both the left and right sides of the variable display unit 35, and a plurality of general winning holes 31 are arranged on both sides of the lower part of the game board 30. 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 which will be 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 to 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, it is easier to form the out port (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.

  On the variable display unit 35, a first symbol display that variably displays an identification symbol or a special symbol (hereinafter referred to as “first symbol” when the identification symbol and the special symbol are collectively referred to) triggered by a winning at the operation port 33. A device 41 is provided. The variable display unit 35 is provided with a center frame 43 so as to surround the first symbol display device 41. A holding lamp 44 corresponding to the first symbol display device 41 is provided on the upper portion of the center frame 43.

In addition, a second symbol display device 42 that variably displays a normal symbol (hereinafter also referred to as “second symbol”) triggered by the passage of the through gate 34 is provided in the upper center of the center frame 43. A holding lamp 46 corresponding to the second symbol display device 42 is provided below the center frame 43. The number of times that the game ball has passed through the through gate 34 is held up to a maximum of 4 times, and the number of the held balls is displayed when the hold lamp 46 is turned on. Note that the hold lamp 46 may be configured so as to be variably displayed on a part of the first symbol display device 41, similarly to the hold lamp 44.

  The 1st symbol display apparatus 41 is comprised as a liquid crystal display device provided with the comparatively large liquid crystal display of 8-inch size, and a display content is controlled by the display control apparatus mentioned later. In the first symbol display device 41, an area where the identification symbol is variably displayed and an area where the special symbol is variably displayed are set. Identification symbols are displayed side by side, and these symbols are variably displayed as they are scrolled in the left-right 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 two types of normal symbols, for example, "(circle)" and "x". When the game ball passes through the through gate 34, the display symbol (ordinary symbol) of the display unit 45 fluctuates. The accompanying electric accessory 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 “” and “×” 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 game balls cannot be won or difficult to win, and can be switched to a predetermined open state in which the game balls are likely to win in a special game state (hereinafter referred to as jackpot). It has become. More specifically, when a game ball wins at the operation port 33, the first symbol display device 41 displays the first symbol (identification symbol and special symbol) in a variable manner, and the jackpot is obtained when the display result described later is displayed at the end of the variation display. Occurs. The variable winning device 32 is configured to be in a predetermined open state so that the game ball can easily win. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, it is assumed that the condition for transition to a round is satisfied, and the variable prize-winning device 32 is repeatedly opened up to a maximum of a plurality of rounds (for example, 15 rounds).

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

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

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

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

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

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

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

  In the present embodiment, the game area is an area of a ball guide passage that is an opposite part of the inner and outer rail parts 51 and 52 among the areas surrounded by the inner rail part 51 and the outer rail part 52 when viewed from the front of the pachinko machine 10. It demonstrates as an area | region remove | excluding. That is, since the game area does not include the ball guide path portion, the left limit position toward the game area is specified by the inner rail portion 51, not by the outer rail portion 52. Further, the right limit position toward the game area is specified by the inner rail portion 51, the lower limit position of the game area is specified by the lower end position of the game board 30 in which the out port 36 is formed, and the upper limit position of the game area. Is specified by the outer rail portion 52. Therefore, in the present embodiment, the width of the gaming area (maximum width in the left-right direction) is 418 mm, and the height of the gaming area (maximum width in the vertical direction) is 445 mm.

  Here, the width of the gaming area is preferably at least 380 mm. More preferably, it is 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. That is, the width dimension of the game area is preferably as large as possible from the viewpoint of game area expansion. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more or 480 mm or more. In other words, the height of the game area is preferably as large as possible from the viewpoint of game area expansion. In addition, about the combination of the said width | variety and height, it can be set as what combined the said numerical value arbitrarily. If the width or height of the game area exceeds a certain value, a part of the game area may exceed the board surface of the game board 30, but other members may be placed along the game board surface in the area beyond the game area. What is necessary is just to supplement by providing.

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 30 is about 70%, which is a much larger area ratio than before. Note that the area ratio of the game area to the surface of the game board 30 has been only about 50% in the related art, so that the game board 30 having the same size as the conventional one is used as in the present embodiment. So, it can be said that the game area is considerably expanded. It should be noted that the external shape of the pachinko machine 10 is almost uniform among manufacturers for the convenience of installation in the game hall, and in the situation where the size of the game board 30 must be the same, the surface of the game board 30 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more. In order to secure 80% or more, it is difficult to make the shape of the game area into a substantially circular shape. Therefore, it is preferable to have a shape in which the corner (for example, the lower right corner or the upper right corner) is expanded. .

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

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

  Notches 38 are formed on both the left and right sides of the game board 30 to avoid interference with the protruding areas from the left and right sides of the main body frame 12, and the maximum width of the game area on the game board 30 in the rail unit 50 It has already been described that the position reaches the left and right end positions of the game board 30, but as will be described later, reinforcing members (bearing brackets 235: FIG. 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. Therefore, if the game ball launched from the game ball launching device does not reach the return ball prevention member 54 and returns as a foul ball in the ball guide passage, the foul ball passes through the foul ball passage 76 to the lower plate 16. To be discharged. Incidentally, in the case of the present embodiment, the length of the launch rail 61 is about 240 mm, and the length of the gap (the length on the extension line of the launch rail 61) leading to the foul ball passage 76 at the tip of the launch rail is about 40 mm. .

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

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

  In addition, a pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 61 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or A game ball guide unit 70 for guiding one of the lower dishes 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. These discharge ports 66 and 67 communicate with a game ball distribution unit 245 (see FIG. 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. This small window 79 is provided in a position corresponding to the relay terminal hole 59 of the game board 30 described in FIG. 4 in substantially the same shape as that, and through the relay terminal hole 59 and the small window 79, the relay installed on the back of the game board. The connection connector 60 of the terminal board is exposed on the front side of the main body frame 12. In such a configuration, various lamps provided on the front door frame 13 side are electrically connected via the connection connector 60 exposed from the small window 79 of the main body frame 12 (resin base 25). A front door frame opening switch 27 for detecting the open state of the front door frame 13 is provided on the top of the resin base 25. The front door frame opening switch 27 has a pin that can be projected and retracted on the front surface of the resin base 25. When the front door frame 13 is closed with respect to the main body frame 12, the pin is pushed in and the front door frame 13 is closed. When the front door frame 13 is opened with respect to the main body frame 12, the pin returns to the protruding position and the opening of the front door frame 13 is detected. When the front door frame 13 is closed with respect to the main body frame 12, the resin base 25 comes into contact with metal fittings (reinforcing plates 131 to 134 shown in FIG. 5) on the back of the front door frame 13, and Metal pieces 28a and 28b are attached to connect the metal fittings to the main body frame 12 side for grounding. Therefore, the metal fittings on the back of the front door frame 13 are conducted to the locking device and the hinge fitting on the main body frame 12 side through the metal pieces 28a and 28b, and are grounded together with the locking device and the hinge fitting.

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

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

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

  Next, the front door frame 13 will be described with reference to FIGS. FIG. 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 portion 101 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be secured, the thickness may be 50 mm or less.

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

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

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

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

  On the back side of the front door frame 13, various metal reinforcing members are provided so as to surround the window portion 101. Specifically, as shown in FIG. 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.

  As shown in FIG. 5, the mounting plates 151 and 152 are attached to the upper and lower ends of the reinforcing plate 131 on the opening / closing axis side which is the right side of FIG. And the assembly | attachment metal fittings 151 and 152 by the side of the front door frame 13 are attached with respect to the support metal fittings 81 and 82 (refer FIG. 3) by the side of the main body frame 12. FIG. That is, a shaft hole that opens to the lower surface is formed in the lower mounting bracket 152, and the protruding shaft 84 of the lower support bracket 82 is inserted into the shaft hole, while the upper mounting bracket 151 By inserting the shaft portion into the support hole 83 of the upper support fitting 81, the front door frame 13 is supported to be openable and closable with respect to the main body frame 12. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. The engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, even in the pachinko machine 10 in which the front door frame 13 is configured in a form including the upper plate 23 and the upper and lower shaft support intervals are increased, the front door frame 13 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front door frame 13 is suppressed.

  A pair of upper and lower hook metal fittings 155 and 156 having a hook shape are attached to the reinforcing plate 132 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, also at the back of the pachinko machine 10. An eaves portion 139 extending toward the surface is provided. In this case, in a state where the front door frame 13 is closed on the main body frame 12 side, a ridge extending along the upper side of the communication port 72 on the main body frame 12 side enters between the ball passage rod 138 and the collar portion 139. Arranged. Therefore, even if a wire, a film, or the like is invaded from the ball passage rod 138 and an illegal act is attempted, it is very difficult to infiltrate the wire, the film, or the like into the game area. As a result, fraudulent acts performed using a wire, a film, or the like can be prevented.

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

  As described above, in the pachinko machine 10 according to the present embodiment, the game area is expanded. Therefore, when the front door frame 13 is closed, the ball guide formed between the inner and outer rail portions 51 and 52 is used. A part of the passage is covered by the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of being caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers a section from the base end portion of the spherical guide passage to the vicinity of the distal end portion along the peripheral edge portion of the window portion 101. ing. In particular, the size and shape of the rail cover 140 on the inner diameter side substantially match those of the inner rail portion 51. Further, at the right end portion of the rail cover 140 (that is, the portion that becomes the right end in the state of FIG. 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. In addition, it is possible to prevent the occurrence of a problem such as being caught in a gap formed between the outer rail portion 52 and the glass 137.

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

  Next, the configuration of the back surface of the pachinko machine 10 will be described. 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 main 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 lined up and down, left and right, or overlapped in the front and rear, 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, the various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. The apparatus 312 (launch control board) and the power supply apparatus 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured to be detachable without using any tools or the like in units of units, and are provided with a support shaft part in a part to form the main body frame 12. Or it has the composition which can be developed to the back of game board 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 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 as viewed from the back of the pachinko machine 10, and the first control board unit 201 can be rotated around the axis A by the support shaft part M1. ing. Further, the first control board unit 201 is provided with a fastening portion M2 made of Nylatch (registered trademark) on the right end portion thereof, that is, on the open end side opposite to the support shaft portion M1, and at the upper end portion with a locking claw. A portion M3 is provided, and the first control board unit 201 is held along the back surface of the main body of the pachinko machine 10 by the fastening portion M2 and the locking claw portion M3. Further, the second control board unit 202 is provided with a support shaft part M4 at the right end when viewed from the back of the pachinko machine 10, and the second control board unit 202 can be rotated around the axis B by the support shaft part M4. It has become. Further, the second control board unit 202 is provided with a fastening portion M5 made of a ny latch or the like on the left end portion thereof, that is, the open end side opposite to the support shaft portion M4, and the second control board unit 202 performs the second control. The substrate unit 202 is held in a state along the back surface of the pachinko machine 10 main body. Further, the back pack unit 203 is provided with a support shaft portion M6 at the right end when viewed from the back of the pachinko machine 10, and the back pack unit 203 is rotatable about an axis C by the support shaft portion M6. . Further, the back pack unit 203 is provided with a fastening portion M7 made of a ny latch or the like on the left end portion thereof, that is, on the open end side opposite to the support shaft portion M6, and at the upper end portion and the lower end portion, respectively, a rotating engagement member. Stop portions M8 and M9 are provided, and the back pack unit 203 is held along the back surface of the pachinko machine 10 main body by the fastening portions M7 and the locking portions M8 and M9.

  The support shaft portions M1, M4, and M6 that rotatably support the units 201 to 203 have a hinge structure that can be easily removed while the units 201 to 203 are opened from the back surface of the pachinko machine 10. Briefly, the first control board unit 201 is developed by releasing the fastening of the fastening part M2 and the locking claw part M3, rotating the unit 201 around the axis A, and expanding the unit 201. Lift in condition. Thereby, if there is no backpack unit 203, the first control board unit 201 can be removed. Further, with respect to the second control board unit 202, the fastening of the fastening portion M5 is released, the unit 202 is rotated about the axis B, is unfolded, and is lifted in that state. Thereby, the 2nd control board unit 202 can be removed. Further, with respect to the back pack unit 203, the fastening portion M7 is fastened and the locking portions M8 and M9 are unlocked, the unit 203 is rotated about the axis C, and is unfolded, 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 configured to expand in opposite directions, the back pack unit 203 must be opened largely beyond a predetermined angle or the unit 203 must be removed. For example, the first control board unit 201 cannot be removed. Accordingly, when attention is paid to removing the first control board unit 201, it is difficult to remove compared to the other units 202 and 203. Furthermore, since the back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation of the locking device, the first control board unit 201 is further removed. Has become difficult. A more specific configuration will be described later.

Therefore, the floating at the installation site of the game ball distributing unit 245 is prevented, and an illegal act caused by entering a wire, a film, or the like from the gap can be prevented. Note that a synthetic resin speaker box 246 is attached to the lower end portion of the main body frame 12 to surround the back of the speaker 20 installed on the back side of the back wall panel 17, and the speaker box 246 transmits the speaker sound to the rear. The sound quality in the low frequency range is improved by functioning so as not to miss.

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

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 271 and the sound lamp control device 272 are mounted on the mounting base 251. The main control device 271 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port for communicating with various devices, and a random number used in various lotteries. A main substrate including a generator, a clock pulse generation circuit used for time counting and synchronization, etc. is provided, and the main substrate is accommodated in a substrate box 273 as an encapsulating means made of a transparent resin material or the like. Configured. The substrate box 273 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected so as not to be unsealed by a sealing unit 274 as sealing means, whereby the substrate box 273 is sealed.

  As long as the sealing unit 274 is configured to connect the box base and the box cover so that they cannot be opened, any configuration can be applied. Here, as shown in FIG. 14 and the like, five sealing members are connected. The box base and the box cover are connected so as not to be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit 274 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation quickly and easily even if unauthorized opening is performed. It is possible to perform the sealing process again even after it has been performed. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 274. When the substrate box 273 is opened, such as when a failure occurs in the accommodated main substrate or when the main substrate is inspected, the connection between the sealing member into which the locking claw is inserted and the other sealing member is disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 273 is left in the substrate box 273, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 273.

  The voice lamp control device 272 includes a CPU that controls voice and lamp display in accordance with instructions from the display control device 214, and a voice lamp control board including other ROM, RAM, various ports, and the like.

A power relay board 276 is mounted on the sound lamp control device 272, and the power of the power supply device 313 is supplied to the display control device 214 and the sound lamp control device 272 via the power relay board 276. .

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

  Here, as shown in FIGS. 15 and 16, the substrate mounting surface 252 is formed with horizontally elongated through holes 256 at two places on the left and right. On the other hand, the substrate box 273 of the main control device 271 is provided with rotationally operable fixtures 277 at two places on the left and right sides of the back surface thereof. When the main controller 271 is mounted on the board mounting surface 252, the main controller 271 is placed so that the fixing tool 277 is inserted into the through hole 256 of the board mounting surface 252, and the fixing tool 277 is placed in this state. The main control device 271 is locked by the turning operation. Accordingly, since the main control device 271 cannot be removed unless the lock 277 is unlocked from the back side of the first control board unit 201, a deterrent effect such as board removal can be obtained.

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

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

  The main control device 271 is arranged on the front side when viewed from the back of the pachinko machine 10, and the sound lamp control device 272 is arranged on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 271 and 272 are mounted in a state where the main controller 271 and the sound lamp controller 272 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with part of them stacked one after the other. That is, as can be seen in FIG. 14 and the like, main controller 271 is arranged in a state where a part thereof (about 1/3 in this embodiment) is floated. Therefore, the voice lamp control device 272 can be extended to a region overlapping the main control device 271. From another viewpoint, the main control device 271 can be extended to a region overlapping the voice lamp control device 272. Even within the limited size of the pachinko machine 10, it is possible to satisfactorily cope with the increase in size of the control boards 271 and 272, and the control devices 271 and 272 can be installed efficiently. Further, when the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252 so that the variable winning device 32 and its electric wiring can be installed without difficulty. Note that lattice-like ribs 258 are provided on the back surface of the substrate mounting surface 252 to increase the support strength of the main controller 271.

  A pair of upper and lower retaining pins 261 are provided on the left end surface of the mounting base 251, and the first control board unit 201 is rotated with respect to the game board 30 by attaching the retaining pins 261 to the bearing fitting 231. Cantilevered so that it can move. A pair of upper and lower nai latches 262 are provided at the right end of the mounting base 251 as fasteners to be fitted into the fastening holes 232. A long hole 263 in which the locking claw piece 233 is locked is provided at the upper end of the mounting base 251. Therefore, the first control board unit 201 is fixed to the game board 30 by fitting the nai latch 262 into the fastening hole 232 and locking the locking claw piece 233 in the long hole 263. It should be noted that the bearing fitting 231 and the latch pin 261 are in the support shaft portion M1, the fastening hole 232 and the ny latch 262 are in the fastening portion M2, and the locking claw piece 233 and the long hole 263 are in the locking claw portion M3. Each corresponds.

  Next, the configuration of the second control board unit 202 will be described with reference to FIGS. 17 is a front view of the second control board unit 202, FIG. 18 is a perspective view of the unit 202, and FIG. 19 is an exploded perspective view of the unit 202.

  The second control board unit 202 has a horizontally long mounting base 301 on which a payout control device 311, a firing control device 312, a power supply device 313 and a card unit connection board 314 are mounted.

Below the tank 355, for example, tank rails 356 having two rows (two rows) of spherical passages and gently inclined toward the downstream side are connected. The tank rails 356 extend in the vertical direction on the downstream side. A case rail 357 is connected. The payout device 358 is provided at the most downstream portion of the case rail 357, and the payout motor 358a is driven by the control of the payout control device 311 so that a required number of game balls are paid out appropriately. The game balls paid out from the payout device 358 are supplied to the upper plate 23 and the like through the payout passage 359 and the like. Although not shown, a tank ball absence sensor that detects the presence or absence of a game ball supplied from the tank 355 or the tank rail 356 is provided upstream of the case rail 357. The payout device 358 is provided with a payout rotation sensor that detects the rotation of the payout motor 358a and a payout count switch that counts the number of game balls to be paid out.

  A vibrator 360 for attaching vibration to the tank rail 356 is attached to the tank rail 356. Vibrator 360 is unitized by a vibrator motor and a synthetic resin case that accommodates the vibrator motor, and is attached to tank rail 356 by two legs 360a. Therefore, if a clogged ball occurs near the tank rail 356, the clogged ball is eliminated by driving the vibrator 360.

  The structure of the tank rail 356 will be described in detail. As shown in FIG. 22, the tank rail 356 has a rail body 361 having a long bowl shape opened upward. A spherical ball receiving portion 362 is formed in the upstream portion of the rail main body 361 so that the game ball dropped from the tank 355 by the ball receiving portion 362 is smoothly taken into the rail main body 361. The rail body 361 is provided with a partition wall 363 extending in the longitudinal direction, and the game balls are divided into two hands by the partition wall 363. The two ball passages partitioned by the partition wall 363 are slightly wider than the diameter of the game ball. On the bottom surface of each spherical passage partitioned by the partition wall 363, one or two ridges 364 are provided, and an opening 365 for dropping dust is provided on the side of the ridge 364. Yes. The rail body 361 is provided with a rectifying plate 367 so as to cover the ceiling portion of the downstream half. The rectifying plate 367 has a bow shape so as to limit the height of the ball passage in the tank rail 356 toward the downstream side, and a convex portion 368 extending in the longitudinal direction is formed on the lower surface thereof. Thereby, each game ball flowing in the tank rail 356 finally flows out downstream without being stacked up and down. Therefore, even if a large amount of game balls flow into the tank rail 356, the game balls are prevented from being bitten and the ball clogging in the tank rail 356 is difficult to occur. The rail main body 361 is formed of a black conductive polycarbonate resin to prevent electrification, while the rectifying plate 367 is formed of a transparent polycarbonate resin so that a clogging of a ball can be visually confirmed. The rectifying plate 367 is detachably provided. By removing the rectifying plate 367, maintenance in the tank rail 356 can be easily performed. A manual stopper 369 for preventing the game ball from flowing down is attached to the current plate 367.

  Returning to the description of FIGS. 20 and 21, the payout mechanism 352 is provided with a payout relay board 381 that relays a payout command signal from the payout control device 311 to the payout device 358, and takes in the main power from the outside.

And the signal regarding the state on the frame side is output to the management control device on the game hall side through these output terminals. Note that an output terminal for outputting a signal every time a predetermined number of game balls are lent out is not necessary in a so-called cash machine.

  The back pack 351 is provided with a substantially rectangular window 391 adjacent to the frame external terminal plate 390. Therefore, in a state where the back pack unit 103 is attached to the main body frame 12, the board external terminal plate 230 on the back side of the game board 30 is exposed through the window portion 391, and the board external terminal plate 230 remains attached with the back pack unit 103 attached. Can be operated. As described above, since the board external terminal plate 230 is attached to the collective board unit 215 in an easily removable state, the board external terminal board 230 is connected to the board via the window portion 391 while being connected. The external terminal plate 230 can be taken out. A main body frame opening switch 392 for detecting the open state of the main body frame 12 is provided at the upper right portion of the back pack 351. When the main body frame 12 is closed with respect to the outer frame 11, the metal of the switch 392 is provided. The contact is closed and the closing of the main body frame 12 is detected. When the main body frame 12 is opened relative to the outer frame 11, the metal contact is opened and the opening of the main body frame 12 is detected.

  The back pack 351 is provided with a pair of upper and lower latch pins 385 at the right end when viewed from the back of the pachinko machine 10. By inserting the latch pins 385 into the bearing portion 238 from above, the back pack unit 203 is mounted. The body frame 12 is cantilevered so as to be rotatable. The back pack 351 is provided with a pair of upper and lower nai latches 386 as fasteners at the left end portion, and is provided with a locking hole 387 at the upper end portion. The nai latch 386 is fitted into the tightened hole 240 and the locking hole. The back pack unit 203 is fixed to the main body frame 12 by rotating the fixing tool 242 after inserting the fixing tool 242 into 387. Further, the back pack unit 203 is also fixed to the main body frame 12 by the fixing tools 241 and 243. The bearing portion 238 and the latch pin 385 correspond to the support shaft portion M6, the fastened hole 240 and the ny latch 386 correspond to the fastening portion M7, and the fixture 242 and the locking hole 387 correspond to the locking portion M8, respectively. To do. Further, the fixture 243 corresponds to the locking portion M9.

  Next, the electrical configuration of the pachinko machine 10 will be described based on the block diagram of FIG.

  The main controller 271 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic unit. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. A RAM 503 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The RAM 503 is configured to retain (backup) data by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is powered off. The RAM 503 temporarily stores various data and the like. In addition to the memory and area for this purpose, a backup area 503a is provided.

  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 processing (see FIG. 37), and restoration of each value written in the backup area 503a is executed in the main processing (see FIG. 29) 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 payout control device 311 controls payout of prize balls and rental balls by a payout motor 358a. The CPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the CPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

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

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

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

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

  The display control device 214 controls the first symbol variation display on the first symbol display device 41 and the second symbol variation display on the second symbol display device 42. 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 controller 271 and the payout controller 311 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 541 outputs the output of 5 volts, which is the drive voltage of the control system, to a normal value for a time sufficient to execute the NMI interrupt processing even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain. Therefore, the main control device 271 and the payout control device 311 can normally execute and complete the NMI interrupt processing.

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

  Next, the structure concerning display control of the first symbol (identification symbol and 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 (variation command, variation time command, confirmation command, etc.) transmitted from the main control device 271 via the input port 527 and analyzes or receives the reception command. A predetermined calculation process is performed based on the command to control the VDP 524 (specifically, generation of an internal command for the VDP 524). The program ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and also stores and holds JPEG format image data for background images. The work RAM 523 is a memory for temporarily storing work data, flags, and the like used when the CPU 521 executes various programs.

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

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

  Here, the display content of the 1st symbol display apparatus 41 is demonstrated based on FIG.

  On the display screen G of the first symbol display device 41, three symbol rows of an upper stage, a middle stage, and a lower stage are set. Each symbol row is composed of a main symbol in which numbers “0” to “9” are respectively attached to a part of a symbol such as a fish, and a sub symbol consisting of, for example, a diamond-shaped symbol. Each main symbol and sub symbol corresponds to an identification symbol. In each symbol row, main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. That is, each symbol row is provided with a total of 20 identification symbols including 10 main symbols and 10 sub symbols. On the display screen G, the 20 identification symbols provided in each symbol row are displayed in a variable manner so as to scroll from right to left with periodicity. In particular, the numbers of the main symbols appear in descending order in the upper symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the lower symbol row. On the display screen G, three symbols of left, middle, and right are displayed in each symbol row, and a total of nine identification symbols of 3 × 3 are displayed when the symbol is stopped.

  Further, a screen area Gs divided by small areas is set at the lower right corner of the display screen G. In the following description, for the sake of convenience, the area of the display screen G excluding the screen area Gs is referred to as “main screen area Gm”, and the screen area Gs is referred to as “sub-screen area Gs”. In the sub-screen area Gs, a special symbol that varies periodically is displayed in addition to the identification symbol. Specifically, as shown in FIGS. 26A to 26C, a special symbol is formed by the ellipse symbol P1 and the straight symbol symbol P2, and these symbols are periodically switched between display and non-display. . Then, if the special symbol is changed and displayed in a state where it becomes a specific symbol, the jackpot is generated. In the present embodiment, there are a state where both the ellipse symbol P1 and the straight symbol symbol P2 are displayed (see FIG. 26A) and a state where only the ellipse symbol P1 is displayed (see FIG. 26B). It is set as a specific symbol. More specifically, if the ellipse symbol P1 and the straight symbol symbol P2 are both displayed, the probability variation jackpot will be obtained, and if only the ellipse symbol P1 is confirmed, the probability variation jackpot will be obtained. Moreover, if it confirms in the state (refer FIG.26 (c)) where only the linear symbol P2 is displayed, it will become the loss | deletion which does not generate | occur | produce a jackpot. Probabilistic jackpot is a jackpot that increases the jackpot probability in the game after the jackpot as an added value, and a non-probable jackpot is a jackpot that does not increase the jackpot probability in the game after the jackpot ends. Say.

  In the main screen area Gm, five effective lines, that is, a left line L1, a middle line L2, a right line L3, a right rising line L4, and a left rising line L5 are set. Then, the variable display stops in the order of the upper symbol row (upper symbol) → lower symbol row (lower symbol) → middle symbol row (middle symbol), and is confirmed when a big win occurs, that is, when the special symbol becomes a specific symbol When the stoppage is made, a combination of jackpot symbols (in the present embodiment, the same main symbol combination) is arranged on one of the active lines, and then the jackpot video is displayed. In addition, when the upper symbol row and the lower symbol row of the identification symbol are stopped in sequence as a big hit, the reach effect is generated when the combination of the same main symbols is displayed on one of the effective lines. In addition, the reach effect also occurs in the special symbol, but there are only two kinds of symbols, the ellipse symbol P1 and the straight symbol symbol P2, and the cycle of the switching display is different only when the reach effect occurs and when it does not occur. Therefore, it is difficult to identify whether or not it is a reach effect by switching display of special symbols.

  As described above, special symbols and identification symbols are set, and special symbols consisting of simple figures are variably displayed in a small area. On the other hand, the person involved in the inspection of the pachinko machine 10 and the like can check the presence or absence of the jackpot from the confirmed result of the special symbol, thereby reducing the inspection load.

  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, the jackpot random number counter C1 used for the jackpot lottery, the reach random number counter C2 used for the reach lottery when the variation time of the special symbol or the special symbol changes and the initial value of the jackpot random number counter C1 A random number initial value counter CINI used for value setting and a command counter CS used for lottery of whether or not to perform a command effect described later are used.

  Each of these counters C1, C2, CINI, and CS is a loop counter in which 1 is added to the previous value each time it is updated, and returns to 0 after reaching the maximum value. 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 reach random number counter C2, and the command counter CS are stored in time series in accordance with the winning history.

  For details of each counter, the jackpot random number counter C1 is configured so that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI is a loop counter similar to the big hit random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the values are “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means a state in which the jackpot probability is increased after the probability variation jackpot is ended, that is, a so-called probability variation state, and the low probability means a time that is not such a probability variation state. In the present embodiment, if the random value “337” is stored in the holding ball storage area at the low probability, a high probability state is obtained after the big hit, and any one of the random values “67, 131, 199, 269, 337” is at the high probability. If it is stored in the reserved ball storage area, the high probability state continues even after the big hit.

  For example, the reach random number counter C2 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 this embodiment, if the value of the reach random number counter C2 is “0 to 21”, the reach effect is performed with a special symbol, and if it is “22 to 238”, the reach effect is not performed with a special symbol. It is said. Note that the reach lottery may be set individually according to the state of the big hit lottery, the number of suspended balls at the start of change, or the like. The reach random number 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.

  Prior to the description of the command counter CS, an outline of the command effect will be first described here.

  The command effect is an effect that changes a condition that causes a jackpot in the identification symbol. At the time of non-command production where the command production is not performed, when the combination of the same main symbols is displayed on any of the effective lines when the upper symbol row and the lower symbol row of the identification symbol stop in order, a reach production occurs. When the middle symbol row stops, a big hit occurs on condition that the combination of the same main symbols stops. On the other hand, when a command effect is performed, for example, when a predetermined symbol of the upper symbol row stops on the active line, or when the upper symbol row and the lower symbol row stop in order, the same symbol on any active line A jackpot occurs on condition that the combination of main symbols is displayed (becomes reach). That is, at the time of command production, the fact that the combination of the same main symbols has stopped on any of the effective lines is not a requirement for generating a jackpot. This is a device for giving inflection to the progress of the game by changing the process leading to the jackpot occurrence.

  For example, the command counter CS 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 command counter CS determines the general contents of the command effect and the number of times the command effect is performed. The command counter CS is updated once every time a normal process to be described later is executed once, and is repeatedly updated even within the remaining time in the normal process. Then, the buffer value of the command counter CS is acquired at the timing when the game ball wins the operating port 33 and stored in the reserved ball storage area of the RAM 503. FIG. 28 shows the relationship between the value of the command counter and the content of the command effect table. “Command effect 1” is a command effect in which a jackpot is generated on the condition that a predetermined symbol in the upper symbol sequence has stopped on the active line, and “command effect 2” means that the upper symbol sequence and the lower symbol sequence are This is a command effect in which a big hit is generated on the condition that the same main symbol combination is displayed on one of the active lines when it stops in sequence (becomes reach). The number of rotations is the number of times that the command effect is performed. Thus, in this embodiment, if the value of the command counter CS is “0 to 19”, the command effect is performed, and if it is “20 to 198”, the command effect is not performed.

  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 sizes of the jackpot random number counter C1, the reach random number counter C2, and the command counter CS are all different prime numbers and are not synchronized in any case. Although not shown, the second symbol random number counter C3 is used for lottery of ordinary symbols. The second symbol random number counter C3 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C3 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 34. The number of random number values to be won is 149, and the range is “5 to 153”.

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

  FIG. 34 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main controller 271 every 2 msec, for example.

  In FIG. 34, in step S501, 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 S502, 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 subsequent step S503, the big hit random number counter C1 and the reach random number counter C2 are updated. Specifically, the jackpot random number counter C1 and the reach random number counter C2 are each incremented by 1, and are cleared to 0 when their counter values reach the maximum values (in the present embodiment, 676, 238, respectively). Then, the updated values of the counters C1 and C2 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, in step S504, 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. 35. In step S601, 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. When it is determined that the game ball has won the operation port 33, in the subsequent step S602, 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 S603 on the condition that there is a winning at the operation port 33 and the number N of activated balls is less than 4, and the number N of activated balls is incremented by one. In the subsequent step S604, the values of the jackpot random number counter C1 and the reach random number counter C2 updated in the step S503 and the value of the command counter CS are stored in the first free area of the reserved ball storage area of the RAM 503.

  Thereafter, in step S605, a command effect determination process for determining whether or not to perform the command effect is performed. This command effect determination process will be described with reference to the flowchart of FIG. For convenience of explanation, the description starts with step S702. In step S702, it is determined whether or not a command effect is performed. Specifically, the value of the command counter CS stored in the reserved ball storage area is confirmed, and the contents of the command effect table shown in FIG. 28 are referred to based on the value. If the value of the command counter CS is 20 to 198, the command effect is not performed, and thus this process is terminated. If the value of the command counter CS is 0 to 19, in order to perform a command effect, the process proceeds to step S703, and a command effect execution process is performed. In step S703, the type of command effect and the number of times of command effect are set in the command effect setting flag storage area and the remaining command effect counter provided in a predetermined area of the RAM 503. For example, when the value of the command counter CS is “0”, since the content of the command effect table is that the command effect 1 is performed 10 times, “1” is set in the command effect setting flag storage area and “10” is set in the remaining command effect counter. To do. Similarly, if the value of the command counter CS is “10”, the content of the command effect table is that the command effect 2 is performed 10 times, so “2” is stored in the command effect setting flag storage area and “10” is stored in the remaining command effect counter. "Is set. Thereafter, the CPU 501 once ends this timer interrupt process. In step S701, it is confirmed whether or not the value of the remaining command effect counter is zero. If the value of the remaining command effect counter is not 0, it means that the command effect is won in the start winning process performed earlier, and this effect is continued. When the value of the remaining command counter is 0, it indicates that the command effect is not continued, so that the process proceeds to step S702 to determine whether or not the command effect is performed as described above.

  In addition, when the game ball wins the operating port 33 (start winning prize), the first symbol display display on the first symbol display device 41 is started accordingly, but after the start winning, the first symbol changes. However, there is a restriction that a predetermined time (for example, 5 seconds) must elapse before the symbol is stopped. Therefore, in the start winning process, when the start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (step S604). 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, C2, and CS at that time.

  FIG. 37 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power supply of the pachinko machine 10 is cut off due to the occurrence of a power failure, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 271 and the CPU 501 interrupts the control being executed. To start NMI interrupt processing. The NMI interrupt processing program in FIG. 37 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within this predetermined time.

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

  The above NMI interrupt processing is executed in the same manner in the payout control device 311, and the state of the payout control device 311 when the power is shut down due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513 by the NMI interrupt. Similarly, power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout controller 311 and the CPU 511 interrupts the control being executed. The NMI interrupt process of FIG. 33 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 29 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 at power-on.

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

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

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch 323. Therefore, if the RAM erase switch 323 is pressed, the process proceeds to a RAM initialization process (steps S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (steps S114 to S116) of the RAM 503 in the same manner. . That is, in step S114, the use area of the RAM 503 is cleared to 0, and in the subsequent step S115, initialization processing of the RAM 503 is executed. In step S116, interrupt permission is set, and the process proceeds to normal processing described later.

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

  Next, the flow of normal processing will be described with reference to the flowchart of FIG. In this normal process, the main process of the game is executed. As an outline, the processing of steps S201 to S206 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S208 and S209 is executed with the remaining time.

  In the normal process, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. In addition, a command command, a variation command, a variation time command, a confirmation command, and the like are transmitted to the display control device 214 when the first symbol display device 41 displays the variation of the first symbol. Each of these commands is transmitted in the order of command command → variable command → variable time command for each normal process (that is, one command every 4 msec), and the command is confirmed when the variable time has elapsed. Is to be sent.

  Next, in step S202, the command counter CS is updated. Specifically, the command counter CS is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (198 in the present embodiment). Then, the update value of the command counter CS is stored in the corresponding buffer area of the RAM 503.

  In step S203, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S204, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed. By this first symbol variation process, jackpot determination, setting of variation time of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

  After that, in step S205, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 35 in the case of the big win state is executed. That is, it is determined whether the big winning opening is opened for each round in the big win state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  In step S206, 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 C3 is acquired and the normal symbol is displayed on the display unit 45 of the second symbol display device 42. Variable display is implemented. Then, when the random number lottery is performed based on the value of the second symbol random number counter C3 and the normal symbol is hit, the electric accessory attached to the operation port 33 is released for a predetermined time. Although the description is omitted, the second symbol random number counter C3 is also updated by the timer interruption process shown in FIG. 34, like the big hit random number counter C1 and the reach random number counter C2.

  Thereafter, in step S207, 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 command counter CS are repeatedly updated within the remaining time until the execution timing of the next normal process (steps S208 and S209). That is, in step S208, 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 S209, the command counter CS is updated. Specifically, the command counter CS is incremented by 1, and each counter value is cleared to 0 when it reaches the maximum value (198 in this embodiment). Then, the update value of the command counter CS is stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S201 to S206 changes according to the state of the game, the remaining time until the execution timing of the next normal process is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the jackpot random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The command counter CS can be updated at random.

  Next, the first symbol variation process of step S204 will be described with reference to the flowcharts of FIGS.

  In the first symbol variation process, in step S301, 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 S302, 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 further is not displaying the variation of the first symbol, the process proceeds to step S303, and it is determined whether or not the number N of actuated balls of the first symbol display device 41 is greater than zero. Then, when the jackpot is being hit or the number N of operation-reserved balls is 0, this processing is terminated as it is.

  If neither the big hit nor the change display of the first symbol is being displayed and if the number N of activated balls is> 0, the process proceeds to step S304. In step S304, 1 is subtracted from the number N of pending operation balls. In step S305, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process for sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side. The reserved first area → the execution area, the reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S306, the first symbol variation start process is executed. Here, the details of the variation start processing will be described using the flowchart of FIG. 32. In step S401, 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 when the probability is low, and “67, 131, 199, 269, 337, 401, 463, 523, 601 and 601 when the probability is high. “661” is the winning value.

  If it is determined that the jackpot is a jackpot, in step S402, a jackpot command is set as a variable command indicating whether the jackpot is a probabilistic jackpot that shifts to a high probability state or a non-probability jackpot that does not transition to a high probability state. In the subsequent step S403, the variation time until the first symbol stops is determined, and this variation time is set in the variation time command. At this time, the variation time of the first symbol is determined based on the value of the command effect setting flag storage area and the value of the reach random number counter C2. Note that the relationship between the value of the reach random number counter C2 and the variation time is defined in advance by the variation time table shown in FIG. FIG. 33A is a variation time table that is referred to when the command effect setting flag value is 0, that is, when the command effect setting flag is 1, and FIG. FIG. 33C is a variation time table that is referred to when the value of the command effect setting flag is 2, that is, when the command effect 2 is performed. When the command effect is not performed, the variation time is relatively long and a plurality of patterns are prepared. On the other hand, when the command effect is performed, the variation time is relatively short and the variation time is uniquely determined. . This is because it is not known whether or not it is a big hit until all the symbol sequences stop when the command production is not performed, so it is considered that various reach productions are performed with identification symbols in order to increase the expectation for the big hit occurrence It is an ingenuity. On the other hand, when performing the command effect, it is possible to know whether the upper symbol row or the upper symbol row and the lower symbol row is a big hit when it stops. It is an ingenuity. After setting the variable time command, a command command is set in step S404. Specifically, the value of the command effect setting flag is checked again and the value of the remaining command effect counter is checked. Set the command. Thereafter, the values of the command effect setting flag and the remaining command effect counter are reset to 0, and this process ends. If the command effect setting flag is 0, this process is terminated without setting the command command.

  If it is determined in step S401 that it is not a big hit, it is determined in step S405 whether or not a reach has occurred based on the value of the reach random number counter C2 stored in the execution area of the reserved ball storage area. In the present embodiment, the value of the reach random number counter C2 is any one of 0 to 238, of which “0 to 21” corresponds to reach and “22 to 238” corresponds to no reach (completely missed). If a reach has occurred, the process proceeds to step S406, where a reach command as a variation command is set. In the subsequent step S407, the variation time until the first symbol stops is determined, and this variation time is set in the variation time command. At this time, similarly to step S403, the variation time of the first symbol is determined based on the value of the command effect setting flag and the value of the reach random number counter C2. Thereafter, in step S408, a command command is set. Specifically, the value of the command effect setting flag is confirmed again and the value of the remaining command effect counter is confirmed. If the command effect setting flag is not 0, a command command corresponding to the value of the command effect setting flag and the remaining command effect counter is set, and 1 is subtracted from the value of the remaining command effect counter. As a result, when the value of the remaining command effect counter becomes 0, the value of the command effect setting flag is reset to 0, and this process ends. If the command effect setting flag is 0, the process ends without setting a command command.

  If it is neither a big hit nor a reach, the process proceeds to step S409 to set a complete out command as a variable command. In step S410, the variation time until the first symbol stops is determined, and this variation time is set in the variation time command. At this time, the variation time of the first symbol is determined based on the value of the command effect setting flag and the value of the reach random number counter C2, as in step S403. Thereafter, a command command is set in step S408, and this process is terminated.

  Returning to the description of FIG. 31, if step S302 is YES, that is, if the variation of the first symbol is being displayed, the process proceeds to step S307, and whether or not the variation time set in the variation start process of step S306 has elapsed. Is determined. When this fluctuation time has elapsed, an affirmative determination is made in step S307, and in step S308, a confirmation command set for confirming the stop symbol is set, and then this process ends.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 38 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

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

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

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

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

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

  In FIG. 39, in step S1001, a command from the main controller 271 is acquired, and the total number of winning balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

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

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

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not 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. If the prize ball is not paid out or the total number of prize balls is 0 (YES in any of steps S1007 and S1008), the process proceeds to the lending / paying process in steps S1010 to S1012.

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

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

  Here, in the prize ball control process shown in FIG. 40, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

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

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

  In the ball lending control process shown in FIG. 41, 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 proceeds to step S1203, where the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process of FIG.

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

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

  In the present embodiment, the program ROM 522 in the display control device 214 is also provided with various counters in the same manner as the CPU 501 in the main control device 271, and specifically, the variation type used for selecting the variation pattern of the special symbol. A counter HC1, a variation type counter HC2 used for selecting a variation pattern of an identification symbol, a stop symbol counter HCU, HCM, HCL, etc. used for setting a stop symbol of the identification symbol are provided. Each of these counters is a loop counter in which 1 is added to the previous value every time it is updated, and returns to 0 after reaching the maximum value. Each counter is updated at short time intervals (for example, 20 msec), and the updated value is appropriately stored in a counter buffer set in a predetermined area of the work RAM 523. In the work RAM 523, a command flag storage area used when performing the command effect and a remaining command counter for counting the number of times the command effect is performed are set in a predetermined area.

  FIG. 42 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. 42, first, in step S1301, it is determined whether or not any command is received from the main controller 271. When step S1301 is NO, it waits until a command is received. When step S1301 is YES, it progresses to step S1302, and it is discriminate | determined whether the command is a command command for performing command production. When the command command is received, command effect selection processing is performed in step S1303. The command effect selection process is a process for determining in detail the command effect roughly determined by the main control device 271. First, it is confirmed whether or not the value of the remaining command counter is 0. If the value of the remaining command counter is 0, the command command provided in the program ROM 522 is determined from the value of the variation type counter HC2 stored in the counter buffer. With reference to the corresponding table, the specific content of the command effect performed with the identification symbol is determined. FIG. 43 shows an example of a table provided in the program ROM 522. 43A is a table used when a command command based on the command effect 1 is received, and FIG. 43B is a table used when a command command based on the command effect 2 is received. . For example, if the value of the variation type counter HC2 when the command command based on the command effect 1 is received is “0”, the command effect that is a big hit if the “0” symbol in the upper symbol row stops on the active line. I do. Similarly, when the value of the variation type counter HC2 when the command command based on the command effect 2 is received is “0”, the command effect that is a big hit is performed if a reach occurs on any of the effective lines. Thereafter, in step S1304, a command flag corresponding to the selected command effect is set in the command flag storage area, and in subsequent step S1305, the number of command effects related to the remaining command counter is set based on the command command. finish. If the value of the remaining command counter is not 0 in step S1303, it means that the command effect based on the command command received before that is being continued. For this reason, after confirming that the value of the remaining command counter and the number of command effects included in the command command are the same, this processing is terminated without performing the processing of steps S1304 to S1305.

  If the command received in step S1302 is not a command command, the process advances to step S1306 to determine whether the received command is a variable command such as a jackpot command or a reach command. If the command is a variation command, the process proceeds to step S1307 to set a special symbol stop symbol corresponding to the variation command, and to change the contents of the command effect performed in the game round and the values of the stop symbol counters HCU, HCM, and HCL. Based on this, a stop symbol of the identification symbol is set, and this processing is terminated.

  If the received command is neither a command command nor a variation command, the process advances to step S1308 to determine whether the command is a variation time command. If the command is a variable time command, the received command is stored in the work RAM 523 in step S1309.

  Subsequently, in step S1310, the variation pattern of the special symbol and the identification symbol is determined based on the information stored in the work RAM 523. The variation pattern of the special symbol and the identification symbol is determined by checking the values of the variation type counters HC1 and HC2 and referring to the variation pattern table set for each variation time based on the value. As a result, various variation patterns can be set even with the same variation time. When the variation patterns of the special symbol and the identification symbol are determined, various arithmetic processes such as generating an internal command for the VDP 524 are started. The internal command is a command for designating a series of display effects from the start to the end of 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 display of the identification symbol or the special symbol on the first symbol display device 41. At this time, the CPU 521 transmits a control command for driving the voices and the lamps to the voice lamp control device 272 in synchronization with the display effect at each time. Thereby, the sound lamp control device 272 drives sounds and lamps in accordance with the control command from the CPU 521. It should be noted that once the variation time command is received, until the confirmation command is received thereafter, the variation display of the special symbol and the identification symbol is continued under the cooperation of the CPU 521 and the VDP 524. Meanwhile, the CPU 521 performs the control of the VDP 524 and the command reception process shown in FIG. 42 in parallel. The control in the sound lamp control device 272 is the same.

  If step S1308 is NO, that is, if the received command from the main control device 271 is not a command command, a fluctuation command, or a fluctuation time command, the command is considered to be a confirmed command. Therefore, in step S1311, as a fixed display process, the VDP 524 is instructed to perform fixed display with a stop symbol, and 1 is subtracted from the value of the remaining command counter. As a result, the VDP 524 confirms and displays the changed symbol as a stop symbol. In this way, a series of display processing from the start of change to the stop of change (definite display) of the special symbol and the identification symbol is performed. The display control device 214 is controlled by the main control device 271 when the change of the special symbol and the identification symbol is started and when the change is stopped. Secured by independent image control. Incidentally, when a big hit occurs at the time of command production, the values of the command flag storage area and the remaining command counter are reset to 0 while the big hit video is being displayed.

  Next, the command effects will be described in detail based on a series of display modes shown in FIGS. 44 (a) to (h) and FIGS. 44 (a) to 44 (h) show one embodiment when the command effect 1 is selected by the main controller 271. FIGS. 45 (a) to 45 (h) show that the command effect 2 is selected. One embodiment at the time is shown. In the following description, for the sake of convenience, the above main symbols are described by numerical numbers assigned thereto, for example, “0” symbol, “1” symbol, etc. In addition, the main symbol after the stop is indicated by a numerical number on the drawing. In addition, in order to facilitate understanding, the description regarding the variation of the special symbol is omitted here.

  As shown in FIG. 44 (a), when the command effect 1 occurs, when the upper symbol row, the middle symbol row, and the lower symbol row start to change, a message (book) In the example, “Take 3 up within 3 revolutions!” Is displayed, and it is taught that if the “3” symbol in the upper symbol row stops on the active line within 3 revolutions, a big hit will be taught. Thereafter, such information is displayed at the top of the display screen, and the symbols in the upper symbol row enter a stop operation. In (b), the message “3” in the upper symbol row has not stopped on the active line, so a message indicating that it will not be a big hit (“command failure” in this example) is an abbreviation of the display screen as shown in (c). The middle symbol row and the lower symbol row are stopped simultaneously while this message is displayed. In addition, when the symbols in the middle symbol row and the lower symbol row are stopped, the special symbol variation display is also ended, and the linear symbol P2 is displayed. As a result, when the message is not displayed as shown in (d), all the symbols including the special symbol are completely displayed, and the stop symbol is confirmed and displayed upon receipt of the confirmation command. The At the start of the next change, as shown in (e), when the upper symbol row, middle symbol row, and lower symbol row start to change, a message (in this example, “two rotations” is displayed again at the approximate center of the display screen. Within 3! ") Is displayed. Thereafter, such information is displayed at the top of the display screen, and the symbols in the upper symbol row enter a stop operation. In (f), since the symbol “3” in the symbol sequence above has stopped on the active line, a message indicating that a jackpot will occur (in this example, “command successful!”) Is an abbreviation for the display screen. The middle symbol row and the lower symbol row are stopped simultaneously while this message is displayed. In addition, when the symbols in the middle symbol row and the lower symbol row are stopped, the special symbol variation display is also terminated, and the ellipse symbol P1 and the straight symbol symbol P2 (or ellipse symbol P1 in the case of non-probable big hit) are displayed Is done. As a result, when the message is not displayed as shown in (h), the variable display of all symbols including the special symbol is completed. At this time, a congratulatory message indicating that a jackpot will be generated (in this example, “jacket! I did it!”) Is displayed at the top of the display screen, and the stop symbol is confirmed and displayed upon receipt of the confirmation command. In this way, at the time of the command effect 1, the reach effect does not occur even if it is a big win, and the control for stopping the combination of the same main symbols on the effective line is not performed.

  As shown in FIG. 45A, when the command effect 2 occurs, when the upper symbol row, the middle symbol row, and the lower symbol row start to change, a message (main book) In the example, “Reach within 5 revolutions!” Is displayed, and it is taught that if the same main symbol stops on any active line within 5 revolutions, it will be a big hit. After that, such information is displayed at the top of the display screen, and the symbols in each symbol row enter the stop operation in the order of the upper symbol row and the lower symbol row. In (b), since the same main symbol did not stop on the active line, a message indicating that it will not be a big hit (in this example, “command failure”) is displayed at the approximate center of the display screen as shown in (c). While the message is displayed, the symbols in the middle symbol row are stopped. In addition, when the symbols in the middle symbol row are stopped, the special symbol variation display is also terminated, and the linear symbol P2 is displayed. As a result, when the message is not displayed as shown in (d), all the symbols including the special symbol are completely displayed, and the stop symbol is confirmed and displayed upon receipt of the confirmation command. The At the beginning of the next change, as shown in (e), when the upper symbol row, middle symbol row, and lower symbol row start to change, a message (in this example, “4 rotations” is displayed again at the approximate center of the display screen. Within reach! ”) Is displayed. After that, such information is displayed at the top of the display screen, and the symbols in each symbol row enter the stop operation in the order of the upper symbol row and the lower symbol row. In (f), since the symbol “2” in the upper symbol row and the lower symbol row has stopped on the left line L1, a message indicating that a jackpot will occur (in this example, “command successful!”) Is shown in (g). Is displayed at the approximate center of the display screen, and the symbol in the middle symbol row stops while this message is displayed. In addition, when the symbols in the middle symbol row are stopped, the special symbol variation display is also ended, and an ellipse symbol P1 and a straight symbol symbol P2 (or an ellipse symbol P1 in the case of a non-probable big hit) are displayed. As a result, when the message is not displayed as shown in (h), the variable display of all symbols including the special symbol is completed. At this time, a congratulatory message indicating that a jackpot will be generated (in this example, “jacket! I did it!”) Is displayed at the top of the display screen, and the stop symbol is confirmed and displayed upon receipt of the confirmation command. In this way, at the time of the command effect 2, even if it is a big hit, the reach effect after the occurrence of reach is not performed, and the combination of the same main symbols is controlled to stop on the effective line. It never happens.

  Note that whether or not to shift to a high probability state in the case of a jackpot at the time of command production is notified on the display screen after the jackpot is finished, and more specifically when the opening of the variable winning device 32 is finished.

  As described above, the process leading to the jackpot occurrence in the identification symbol changes between the command presentation 1, the command presentation 2, and the non-command presentation, while the process leading to the jackpot occurrence in the special symbol does not change. That is, if both the ellipse symbol P1 and the straight symbol symbol P2 are confirmed and displayed, the probability variation jackpot is obtained. This also makes it possible to reduce the inspection load on the parties involved in the inspection of the pachinko machine 10 and the like.

  Next, a difference in variation time between the non-command effect and the command effect in the case of a big hit will be described based on the time chart of FIG. In the present embodiment, the time from when the symbols in each symbol row start to change until the upper symbol and the lower symbol stop is the same, but it goes without saying that the configurations may be different.

  FIG. 46 (a) shows symbol variations when the command effect is not performed. The symbols and special symbols of each symbol row of the identification symbol start to change all at once, and then the upper symbol enters a stop operation at a timing when a predetermined time t1 has elapsed. Subsequently, the lower symbol enters the stop operation at the timing (predetermined time t2) when the upper symbol stops, the reach effect starts when the reach occurs, and the middle symbol enters the stop operation at the timing when the predetermined time t4 elapses. In accordance with the timing when the change of the middle symbol ends (predetermined time t5), the special symbol also ends the change display. Thereafter, the stop symbol of each symbol is confirmed and displayed with the reception of the confirmation command (predetermined time t6).

  FIG. 46B shows symbol variation when the command effect 1 is performed. The symbols and special symbols of each symbol row of the identification symbol start to change all at once, and then the upper symbol enters a stop operation at a timing when a predetermined time t1 has elapsed. In the command effect 1, the middle symbol and the lower symbol enter the stop operation at the timing (predetermined time t2) when the upper symbol stops. At this time, a big win message (in this example, “command successful!”) Is displayed, and the middle symbol, the lower symbol, and the special symbol finish changing at a timing (predetermined time t3) when this message is not displayed. Thereafter, the stop symbol of each symbol is confirmed and displayed with the reception of the confirmation command (predetermined time t7).

  FIG. 46 (c) shows symbol variation when the command effect 2 is performed. The symbols and special symbols of each symbol row of the identification symbol start to change all at once, and then the upper symbol enters a stop operation at a timing when a predetermined time t1 has elapsed. Subsequently, the lower symbol enters the stop operation at the timing (predetermined time t2) when the upper symbol stops, and the middle symbol enters the stop operation at the timing (predetermined time t3) when the lower symbol stops in the command effect 2. At this time, a message that is a big hit (in this example, “command successful!”) Is displayed, and the middle symbol and the special symbol finish changing at a timing (predetermined time t8) when this message is not displayed. Thereafter, the stop symbol of each symbol is confirmed and displayed with the reception of the confirmation command (predetermined time t9).

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

  By performing a command effect on the first symbol display device 41, a process of starting variation → reach effect generation → stopping with a combination of the same main symbols leads to a big hit occurrence from the process of variation start → command content establishment → variation stop. It is possible to change the process, and to give an inflection to the progress of the game. That is, a general player pays attention to the final stop symbol (the symbol in the middle symbol row) after the reach effect is generated if it is a non-command effect, and if the command content is 1 time, the command content is displayed in the upper symbol string. Whether or not to stop, if it is the command effect 2 point, it will be watched whether or not it will reach when the symbol in the lower symbol sequence stops, the point to watch the symbol variation according to each effect Because changes. In addition, it is possible to clarify the difference between command and non-command effects by configuring the jackpot to occur even if the same main symbol combination is not aligned on the effective line when commanded. Thus, it is possible to enhance the interest of the game. For example, when a jackpot occurs in the command effect 1, if the symbol variation in which the symbols in the upper symbol sequence stop at the command content and then stops at the same main symbol combination through the reach effect, the combination of the same main symbols This is because the player may feel that a big hit will not occur regardless of the presence or absence of the command effect unless it is stopped at this point, and the significance of performing the command effect will be buried. Furthermore, even when the variation display of the symbol sequence that is not related to the content of the command is shortened at the time of the command production, the interest of the game is not impaired, so the variation time at the command production is shorter than the variation time at the non-command production At the time of teaching the success or failure of the command content, the player has a passive impression that the player is being forced to show the variation of the symbol by ending the variation display of the symbol sequence being varied. Can be suppressed.

  By providing a variable time table separately for commanded and non-commanded effects, it is possible to uniquely determine the variable time based on the value of the reach random number counter C2, and the control load of the main control device 271 can be determined. It becomes possible to reduce.

  A special symbol with a small number of symbols and an identification symbol with a large number of symbols are set, the main controller 271 determines the variation time of special symbols, the presence / absence of reach, etc., and the display controller 214 determines the variation pattern of special symbols and identification symbols. By adopting a configuration that determines the stop symbol and the variation pattern, it is possible to reduce the control load of the main controller 271. The main control device 271 needs to comprehensively manage main control related to the game, such as control of the payout control device 311 and the display control device 214. For this reason, the processing time which can be spent on the fluctuation display of the symbol in the main controller 271 is limited. Therefore, the main control unit 271 determines the variation time of special symbols with a small number of symbols, the presence / absence of reach, etc., and the display control unit 214 adjusts the variation pattern of special symbols and the stop symbol of the identification symbol so as to match the variation time of special symbols. By adopting the configuration for determining the variation pattern, it is possible to diversify the variation display of symbols while reducing the control load on the main control device 271.

  By displaying the command content at the time of command production on the display screen, it is possible to see the variation display of the first symbol and confirm the command content in parallel, and to immerse the player in the game Is possible. In addition, it is possible to dispel the possibility that the player will be confused by changing the conditions for generating jackpots between commanded and non-commanded effects, and to reduce the possibility of the player overlooking the command content. Is also possible.

  By providing a command effect 1 that indicates whether or not a big hit is obtained when the upper symbol row is stopped as a command effect, and a command effect 2 that indicates whether or not a big hit is obtained when the upper symbol row and the lower symbol row are stopped The process leading to the jackpot generation can be made rich in variations, and the entertainment of the game can be suitably enhanced.

  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-described embodiment, the special symbol is displayed at the lower right corner of the first symbol display device 41. However, the special symbol display unit may be provided and displayed at a predetermined portion of the game area. The predetermined figure may be turned on and off by an illumination member such as a lamp.

  (B) In the above embodiment, a special symbol is composed of the ellipse symbol P1 and the straight symbol P2, but a special symbol symbol may be composed of three or more types of symbols. However, from the viewpoint of reducing the control load on the main control device, in such a case, it is desirable that the display control device determines the stop symbol when the special symbol is out of place. Alternatively, the special symbol may be a symbol such as a character, and the character may perform a predetermined action. In this case, it is possible to produce an effect that enhances the interest of the game from the special symbol.

  (C) In the above embodiment, the display control device 214 receives various commands from the main control device 271 and determines the variation pattern of the identification symbol and the special symbol, but the sound lamp control device 272 is the main control device. A configuration may be adopted in which various commands are received from 271 to determine the variation pattern of the identification symbol and the special symbol.

  (D) In the above embodiment, the control for stopping the identification symbol with the combination of the same main symbol is not performed at the time of the command effect. However, when the jackpot is reached, the control for stopping with the combination of the same main symbol is performed. Needless to say.

  (E) In the above embodiment, in the case of a big hit, each symbol sequence is set so that the combination of the same main symbols is stopped at the time of non-command production, and the command conditions are satisfied at the time of command production. Although it is configured to perform variable display of symbols, it may be configured to be a big hit even if the command condition is not satisfied if the combination of the same main symbols stops. With such a configuration, the command production is given pleasure of watching whether or not the command condition is satisfied and pleasure of watching whether or not to stop with the same main symbol combination even if the command condition is not satisfied. It becomes possible to increase the interest of the game.

  (F) In the above embodiment, when the symbol sequence related to the command content at the time of the command effect (for example, the upper symbol sequence in the command effect 1) stops, the command success or the command failure is displayed. Although the variation display is ended, the configuration is not limited to this configuration as long as the variation time is shorter than the variation time at the time of non-command production.

  (G) In the above embodiment, the variation time at the time of the command effect is set to 7 seconds for the command effect 1 and 10 seconds for the command effect 2. However, various different time periods may be set. Needless to say. However, in this case, for example, in the case of the command effect 1, the time required for the upper symbol sequence to change is changed, and the average change time in each change time table is the average of the change time table that is referred to during the non-command effect. It is desirable to set so as to be shorter than the fluctuation time. This is because, if the variation after the success or failure of the command content is determined to be long, the player may have an impression that the symbol variation display is forcibly shown.

  (H) In the above embodiment, the command effect determination process is performed during the start winning process, but the present invention is not limited to this timing, and the command effect determination process may be performed during the variation start process. Moreover, it is good also as a structure which performs an instruction | indication effect determination process, when the random value which becomes a big hit in a start winning process is acquired, or when it is determined that it is a big win in a fluctuation start process. In such a case, it becomes possible to closely associate the command effect with the jackpot occurrence, so that it is possible to enhance the interest of the game.

  (I) In the above-described embodiment, the command effects include an effect that indicates whether or not a jackpot has occurred when the upper symbol sequence is stopped, and an effect that indicates whether or not a jackpot has occurred when the upper symbol sequence and the lower symbol sequence are stopped. Although it was set as the structure, what is necessary is just the structure which can know the presence or absence of jackpot before all the symbol sequences complete | finish a fluctuation | variation. For example, a command effect that generates a big hit when a predetermined symbol is stopped in the lower symbol row may be set, or if an identification symbol that scrolls from right to left scrolls from left to right, a big hit will occur A command effect may be set. Even if a plurality of command effects are set as described above, if the display control device 214 selects the command effect contents, there is no fear that the processing load of the main control device 271 will increase, and various progresses of the game will occur. It is possible to give inflection.

  (J) In the above embodiment, the jackpot is generated if the command content is successful once. However, the jackpot may be generated when the command content is successful a plurality of times. For example, a command effect such as “reach 3 times within 5 revolutions” may be performed. In such a case, it is possible to increase the degree of expectation for occurrence of a jackpot across a plurality of game times, and it is possible to increase the interest of the game. However, in order to perform this command effect, it is necessary that the reserved ball storage area has at least two operation opening winning memories, and further, the reach is set to 1 at the initial game time when the display control device starts the command effect. It must be generated once or twice in advance. This is because there is a possibility that the third reach may not be achieved in the game times in which the jackpot is generated.

  (K) In the above-described embodiment, the instruction content is taught on the first symbol display device 41. However, instead of or in addition to this, the instruction content may be taught by voice or the like.

  (L) In the above-described embodiment, it is configured not to teach a condition that is a big hit at the time of a non-command effect. If it is a configuration that always teaches the conditions for winning big hits, the player can immerse themselves in the game without being confused even if the process leading to the occurrence of the big hit is changed by the command effect.

  (M) In the above-described embodiment, the pachinko machine 10 having a relatively large game area compared to the prior art has been described. However, the present invention is not limited to this, and a conventional game machine such as a pachinko machine having a game area, a window, or the like. It can also be applied to. Also applicable to other types of ball game machines different from the above embodiment, such as pachinko machines equipped with a display screen and other objects, arrange ball machines equipped with a display screen, sparrow balls, etc. it can. In addition, it can also be applied to a swivel type gaming machine such as a slot machine, and a ball-type belt type gaming machine that uses a gaming ball such as a pachinko ball as a gaming medium.
