Although a specific illustration is omitted, a support shaft for cantilevering the ashtray 21 in a rotatable state is provided on the right side surface of the ashtray 21, and the ashtray 21 is located upward on the back as shown in the figure. A locking portion that is locked to the base portion 15 is provided at a position that is open to the bottom. Most of the front plate 14 is formed of ABS resin in the same manner as the main body frame 12. The front plate 14 is exposed on the front side of the pachinko machine 10, but by molding it with ABS resin, it is possible to plate appropriate portions of the surface for the purpose of decoration or the like. In addition, since the ashtray 21 is disposed in the vicinity, a flame retardant ABS resin is used for the parts constituting the lower plate 16 and the back wall panel 17, so that it is difficult to burn even if cigarettes are mistakenly 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. In the present embodiment, the opening / closing member is configured by the front door frame 13 along with 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. .

A ball removal lever 24 for the upper plate 23 is provided on the front surface side of the bulging portion 22, and when this ball removal lever 24 is operated, a ball removal passage (not shown) provided near the most downstream portion of the upper plate 23. Is opened, and the stored balls in the upper plate 23 are discharged to the lower plate 16. In addition, the upper plate 23 can also be comprised with a flame-retardant ABS resin similarly to the lower plate 16 grade | etc.,.

  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 this pachinko machine 10, for the purpose of expanding the game area, a large glass 137 is mounted on the front door frame 13 along with the expansion of the game area. Therefore, although the frame portion around the glass becomes narrow and there is a concern about the problem of strength reduction, sufficient strength of the glass support structure can be ensured by providing a frame portion integrated with the upper plate below the glass. The vertical and horizontal dimensions of the glass 137 are generally 405 mm × 405 mm, whereas the pachinko machine 10 has a size of 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 one existing model, whereas in this pachinko machine 10, it is about 30 mm smaller, about 172 mm. It has become. 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, about 261 mm in the present pachinko machine 10. Here, by lowering the position of the upper plate 23, the vertical distance from the tip of the nozzle of the ball lending device arranged side by side on the left side of the pachinko machine 10 in the game hall is increased, and there is a concern that the lending of the lending ball may be lost. However, in the present embodiment, the rising portion 22a in which the wall surface of the bulging portion 22 is higher than the other wall surface is formed in the left side portion that is the rental ball discharge portion from the nozzle. Thereby, even if it has the structure which lowered the position of the top plate 23, inconveniences, such as spilling of a rental ball, are eliminated. The height of the raised portion 22a may be any as long as it matches the lowered size of the upper plate 23, and the maximum height is 25 mm in the present embodiment.

In addition, the 1st symbol display device 41 is equipped with liquid crystal displays of 10 inches other than 8 inches, 7 inches, etc., equipped with a wide size display, or other types such as CRT, dot matrix, 7 segments, etc. A display screen may be configured.

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

  The variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which the game ball is likely to win in a special game state (hereinafter referred to as a jackpot). It has become. More specifically, when a game ball wins in the operating port 33, the first symbol display device 41 displays the first symbol in a variable manner, and when the confirmed symbol after the stop becomes a combination of specific symbols set in advance, a big hit is given. Occur. The variable winning device 32 is configured to be in a predetermined open state so that the game ball can easily win. As an opening mode of the variable prize winning device 32, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that a winning is made to a continuous prize opening in the variable prize winning device 32. In general, it is assumed that the condition for shifting to a round is satisfied, and the variable prize-winning device 32 is repeatedly opened up to a maximum of a plurality of rounds (for example, 15 rounds).

  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 formed 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. The outer rail portion 52 has a support portion 52a that is integrally formed with other resin portions in the same manner as the inner rail portion 51, and is provided upright substantially vertically 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 channel | path is formed in the groove shape opened to the near side. Has been.

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

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

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

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

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

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

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

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

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

  In connection with the expansion of the game area, the through gates 34 located on both sides of the variable display unit 35 have a guide mechanism that allows the game balls that have passed through the gate 34 to be moved toward the center. As a result, even when the game area is expanded in the left-right direction, the game ball can be guided toward the central operation port 33 and the variable prize-winning device 32, and thus the game area is expanded. As a result, a decrease in interest due to the difficulty of winning a game ball is suppressed. Further, since the game area is expanded in the left-right direction, even if a relatively large variable display unit 35 is provided 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 the game ball in the game areas on the left and right sides of the variable display unit 35 It is not monotonous and you can fully enjoy the behavior of the game ball.

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

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

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

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

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front door frame 13 side (ball outlet leading from the most downstream portion of the upper plate 23). At this time, since the launch position of the game ball is lowered in this embodiment, the drop from the exit of the ball on the front door frame 13 side to the launch position becomes large, Guide members 63 and 64 are installed on the front side. Thereby, the game ball supplied from the ball exit on the front door frame 13 side is always set at a predetermined launch position, and a stable launch operation can be realized. In addition, the game ball launching device is provided with a ball striking rod that is supported so as to be rotatable about the base end portion, and a game ball is launched along with the rotation of the ball striking ball. It is rare. Therefore, while aiming to reduce the weight of the hitting ball by changing the material to a light metal such as aluminum and reducing the size of the hitting shaft, the head portion of the hitting ball (opposite to the base end) is required to ensure sufficient firing force. A weight is provided at the tip of the side. Thereby, sufficient and stable launch of the game ball can be realized. By providing the weight portion of the hitting ball projecting upward, the hitting ball can be easily picked or 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. In other words, 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, when the front door frame 13 is closed, the opening / closing plate 73 is pushed open against the biasing force of the spring 75 by a 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 (downward position) different from the position that is the maximum width of the game area. The cylinder lock 91 has a function to cover both the locking and unlocking of the main body frame 12 and the locking and unlocking of the front door frame 13, and when the key inserted into the key hole is turned counterclockwise (counterclockwise direction) When the key is unlocked and the key is turned to the right (clockwise direction), the front door frame 13 is unlocked.

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

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

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

  The left and right frame portions of the front door frame 13 are restricted in reducing the frame width, and need a sufficient width dimension 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 see 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. A protrusion (or a wavy protrusion) is provided in the direction of the protrusion. The outer resin cover layer is transparent, and the inner resin cover layer is colored. Therefore, if the annular illumination part 102 is caused to emit light, it is possible to realize the illumination in a state of being dispersed in a large number or in a state accompanied with a stereoscopic effect. A resin material containing glass powder may be used for the resin cover layer. Such a configuration of the resin cover layer can also be applied to other electric decoration parts (for example, the central electric decoration part 103 and the prize ball lamp 105).

  The front door frame 13 is provided with a ball rental operation portion 120 at a position below the window portion 101. The ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. A ball lending operation, a card return operation, and 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 (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 addition, in a pachinko machine (so-called cash machine) in which game balls are lent out directly from a ball lending device or the like without using a card unit, the ball lending operation unit 120 is unnecessary. A decorative sticker or the like is attached to 120 installation portions. Thereby, in the configuration of the pachinko machine 10 provided with the ball rental operation unit 120, the pachinko machine using a card unit (so-called CR machine) and the cash machine can be shared.

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

  Assembling mechanisms for the main body frame 12 are attached to the upper and lower ends of the reinforcing plate 131 on the opening / closing axis line on the right side of FIG. Then, the mounting brackets 151 and 152 on the front door frame 13 side are attached to the support brackets 81 and 82 (see FIG. 3) on the main body frame 12 side. That is, a shaft hole that opens to the lower surface is formed in the lower mounting bracket 152, and the protruding shaft 84 of the lower support bracket 82 is inserted into the shaft hole, while the upper mounting bracket 151 By inserting the shaft portion into the support hole 83 of the upper support fitting 81, the front door frame 13 is supported to be openable and closable with respect to the main body frame 12. Further, the reinforcing plate 131 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof, and the engaging claw 131a is formed in the hole 12a ( (See FIG. 3). Thereby, even in the pachinko machine 10 in which the front door frame 13 is configured in a form including the upper plate 23 and the upper and lower shaft support intervals 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 opening / closing axis line on the left side of FIG. These metal fittings 155 and 156 extend rearward and are provided so as to correspond to the insertion holes 87 and 88 (see FIG. 3) provided in the main body frame 12. When the front door frame 13 is closed with respect to the main body frame 12, the metal fittings 155 and 156 are inserted into the insertion holes 87 and 88 on the main body frame 12 side and are locked by the locking device.

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

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

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

  As described above, 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 with the front door frame 13. Therefore, in the ball guide passage, a portion where the opening portion on the near side cannot be covered with the glass 137 is formed. In such a case, for example, when the game ball launched from the game ball launching device returns without reaching the return ball prevention member 54, the game ball jumps out of the ball guide passage or between the outer rail portion 52 and the glass 137. There is a risk of getting caught in a gap that can be made. Therefore, in the present embodiment, a rail cover 140 is attached to the front door frame 13 so as to cover the front side opening portion of the ball guide passage. The rail cover 140 is a plate having a substantially arc shape, and is formed of a transparent resin. The rail cover 140 has an arc shape corresponding to the shape of the spherical guide passage, and covers 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 shown in FIG. 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 that extends in an arc shape along the inner edge and protrudes rearward is formed. The protrusion 142 is disposed so as to overlap the inner rail portion 51 in a state of entering the ball guide passage when the front door frame 13 is closed. Therefore, for example, even if a wire or a film is intruded through 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 ridge 142 may be formed in a wider range, for example, along the entire inner edge of the rail cover 140. According to such a configuration, it becomes difficult for a wire, a film, or the like to enter in a wider range, It is possible to more reliably prevent fraudulent acts performed using a wire, a film, or the like.

  Next, the configuration of the back surface of the pachinko machine 10 will be described. 6 is a rear view of the pachinko machine 10, and FIG. 7 is an exploded perspective view showing the rear structure of the pachinko machine 10 for each 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 stacked in front and back, and a game ball supply device for supplying game balls (Discharge mechanism), a protective cover made of resin, and the like are attached. In the present embodiment, various control devices are separately mounted on two mounting bases to form two control board units, and these control board units are individually attached to the main body frame 12 or the back of the game board 30. ing. In this case, the main controller 271 (main board) and the audio lamp controller 272 (audio lamp control board) are mounted on one mounting base to form a unit, and the payout controller 311 (payout control board) and launch control. A device 312 (launch control board) and a power supply device 313 (power supply board) are mounted on the other mounting base to form a unit. Hereinafter, for the sake of convenience, the former unit is referred to as a “first control board unit 201”, and the latter unit is referred to as a “second control board unit 202”. Further, since the dispensing mechanism and the protective cover are 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 so that the main body frame 12 Or it has the composition which can be developed to the back of game board 30. This is also a device for making it possible to easily check a hidden portion when the units 201 to 203 and other components are arranged one behind the other. Actually, as shown in the schematic diagram of FIG. 8, the first control board unit 201 having a substantially L-shape is arranged at substantially the center of the pachinko machine 10, and the second control board unit 202 is arranged therebelow. Yes. Further, the back pack unit 203 is disposed in a region partially overlapping with the first control board unit 201.

  The first control board unit 201 is provided with a support shaft part M1 at the left end portion when viewed from the back of the pachinko machine 10, and the first control board unit 201 can be rotated around 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 with a locking claw at the upper end portion. 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 at 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 part 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 part 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 in a state where 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 and rotating the unit 201 around the axis A, 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. 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 left when viewed from the back of the pachinko machine 10, whereas the second control board unit 202 and the back pack unit. 203 is configured to open to the right. In this case, since the first control board unit 201 is partially overlapped with the back pack unit 203, it is impossible to remove the first control board unit 201 without opening the back pack unit 203. Furthermore, since the first control board unit 201 and the back pack unit 203 are each configured to expand in the opposite direction, the back pack unit 203 must be opened largely beyond a predetermined angle or removed. For example, the first control board unit 201 cannot be removed. Accordingly, when attention is paid to removing the first control board unit 201, the removal is difficult compared to the other units 202 and 203. Furthermore, since the back pack unit 203 cannot be opened unless the main body frame 12 is opened with respect to the outer frame 11 by key operation of the locking device, the first control board unit 201 is further removed. Has become difficult. A more specific configuration will be described later.

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

A part of is exposed.

  Here, the configuration of the locking device according to the present embodiment will be described with reference to FIGS. FIG. 23 is a front view of the locking device, FIG. 24 is a rear view thereof, FIG. 25 is a right side view thereof, and FIG. 26 is a left side view thereof. Further, FIG. 27 is an exploded rear view of the locking device, FIG. 28 is an exploded right side view of the locking device, FIG. 29 is a rear view showing a state when the front door frame 13 is unlocked, and FIG. Each right side view is shown.

  The vertically long base frame 247 constituting the locking device includes a mounting plate 2 and a support plate 3, which are integrally formed in a substantially L-shaped cross section. As shown in FIGS. 9, 10, and 30, the locking plate according to the present embodiment has the attachment plate 2 attached to the back side of the main body frame 12 in the vertical direction.

  As shown in FIGS. 23, 27, and 29, the mounting plate 2 has a plurality of mounting holes, and rectangular insertion holes 158 and 159 are formed at the upper and lower portions thereof. When the front door frame 13 is closed, door frame flange portions 155 and 156, which will be described later, enter the insertion holes 158 and 159. Further, as shown in FIG. 29, guide pins 2a and 2b for guiding sliding of door frame locking members 161 and 162, which will be described later, are mounted on the mounting plate 2 below the insertion holes 158 and 159. It has been.

  Inside the support plate 3, a sliding rod 248 as a moving member is slidably arranged up and down. The flange members 4 and 5 as the locking members (first locking members) provided on the upper and lower portions of the base frame 247 come to slide in conjunction only when the sliding rod 248 moves upward. Yes. As shown in FIG. 30, receiving metal fittings 164 and 165 are fixed inside the outer frame 11 so as to correspond to the flange members 4 and 5. The sliding rod 248 is formed in a band shape from a metal plate.

  As shown in FIG. 28, guide holes 248e and 248f are provided at the upper and lower portions of the sliding rod 248, and an operation portion 248g for manual operation is provided at the intermediate portion, and above the lower guide hole 248f. Are formed with two rectangular engaging portions 248c and 248d with which a cam plate 8 described later can be engaged. When the main body frame 12 is unlocked, when the key K is inserted and the key operation is performed clockwise with respect to the cylinder lock 91, a first engagement convex portion 8a of the cam plate 8 described later is engaged with the engagement portion 248d. Match. Further, when the front door frame 13 is unlocked, the second engaging convex portion 8b of the cam plate 8 is engaged with the engaging portion 248c when a key operation is performed counterclockwise with respect to the cylinder lock 91. The key K and the cylinder lock 91 constitute an external operation means.

  The upper and lower flange members 4 and 5 have triangular heads, and the lower ends of the tips are engaging portions. 26 and 27, guide pins 4a and 5a are respectively fixed to the upper and lower flange members 4 and 5, and the guide pins 4a and 5a are provided on the upper and lower portions of the support plate 3, respectively. The oval guide holes 3a and 3b are inserted in an engaged state. Further, the eaves members 4 and 5 are guided by guide portions 3 c and 3 d provided on the upper and lower portions of the support plate 3. That is, the flange members 4 and 5 are supported by the guide pins 4a and 5a and the guide portions 3c and 3d so as to be slidable up and down within a predetermined range.

  The guide pins 4a and 5a are inserted into the guide holes 248e and 248f of the sliding rod 248, and coil springs 9b and 9d are hung between the flange members 4 and 5 and the mounting plate 2, and the flange member 4 and 5 are always pulled downward. The guide pins 4 a and 5 a are in contact with the lower edges of the guide holes 248 e and 248 f of the sliding rod 248 and the guide holes 3 a and 3 b of the support plate 3.

  Accordingly, as the sliding rod 248 slides upward, the flange members 4 and 5 also move upward in conjunction with each other. On the other hand, each of the eaves members 4 and 5 is independently movable upward, and when the upper and lower eaves members 4 and 5 are moved upward with a wire or the like (when an illegal act is performed) The wire must be hooked on both hook members 4 and 5 and pulled up. That is, since it is configured such that only one hook member 4 or 5 can be hooked and pulled upward, unlocking cannot be performed in practice.

  The door frame locking members 161 and 162 as the locking members (second locking members) constituting the door frame locking mechanism are formed by bending a metal plate into a U-shaped cross section as shown in FIGS. Yes. Rectangular locking holes 167 and 168 are formed on the surface of the door frame locking members 161 and 162 on the mounting plate 2 side, and the locking holes 167 and 168 are formed in the mounting plate 2. 159 is disposed opposite to 159.

  The door frame locking members 161 and 162 are provided with guide holes 161a, 161b, 162a, and 162b, respectively. Is engaged. Guide pins 2a and 2b fixed to the upper and lower portions of the mounting plate 2 are engaged with the guide holes 161b and 162b. Coil springs 9 a and 9 c are hung between the door frame locking members 161 and 162 and the mounting plate 2.

  Under such a configuration, the door frame locking members 161 and 162 are always pulled upward, the guide pins 2a and 2b abut on the lower edges of the guide holes 161b and 162b of the door frame locking members 161 and 162, and the guides The pins 248a and 248b stop in a state where they are in contact with the lower edges of the guide holes 161a and 162a of the door frame locking members 161 and 162. In such a stop position of the door frame locking members 161 and 162, the locking holes 167 and 168 are positioned relative to the upper portions of the insertion holes 158 and 159 on the mounting plate 2 side.

  When the front door frame 13 is closed, the door frame flanges 155 and 156 (see FIGS. 29 and 30) provided on the front door frame 13 side enter the locking holes 167 and 168, respectively. At this time, the door frame locking members 161 and 162 are pushed by the flange portions 155 and 156 and slide downward against the tensile force of the coil springs 9a and 9c, and then the tension of the coil springs 9a and 9c. Returning to the original position by force, the door frame flanges 155 and 156 are locked. Further, the door frame locking members 161 and 162 slide downward as the sliding rod 248 slides downward during unlocking. As a result, the engagement between the door frame flange portions 155 and 156 and the locking holes 167 and 168 is released.

  A deformed hole for mounting the cylinder lock 91 is formed in the widened portion at the lower portion of the mounting plate 2, and a mounting bracket portion 170 is formed corresponding to the deformed hole. The mounting bracket portion 170 is formed by notching a part of the mounting plate 2 and bending the upper and lower notch pieces inwardly in a hook shape. The tip of the cylinder lock 91 is fixed to the mounting bracket 170 while being inserted into the deformed hole of the base frame 247. More specifically, the cylinder lock 91 has a flange 91 a at the tip portion thereof, and the flange 91 a is attached to the mounting bracket portion 170 in a state where a part of the main body of the cylinder lock 91 is inserted inside the base frame 247. It is fixed with screws.

  A cam plate 8 having a first engagement convex portion 8 a and a second engagement convex portion 8 b is fixed to the lock shaft of the cylinder lock 91. When the cam plate 8 is rotated counterclockwise in FIG. 24 by the key operation, the first engagement convex portion 8a of the cam plate 8 is engaged with the engagement portion 248d of the slide rod 248, and the slide rod 248 is engaged. Slides upward. Thereby, the eaves members 4 and 5 slide upward. At this time, the engagement between the flange members 4 and 5 and the metal fittings 164 and 165 on the outer frame 11 side is released, and the main body frame 12 is unlocked. Therefore, the locking / unlocking mechanism of the main body frame 12 with respect to the outer frame 11 is formed by the flange members 4 and 5, the sliding rod 248, the cam plate 8, the cylinder lock 91, and the like.

  On the other hand, when the cam plate 8 is rotated in the clockwise direction of FIG. 248 slides downward, and the door frame locking members 161 and 162 slide downward. At this time, the engagement between the door frame locking members 161 and 162 and the door frame flange portions 155 and 156 on the front door frame 13 side is released, and the front door frame 13 is unlocked. Therefore, a locking / unlocking mechanism for the front door frame 13 is formed by the door frame locking members 161 and 162, the sliding rod 248, the cam plate 8, the cylinder lock 91, and the like.

  Here, in this type of conventional locking device, the upper and lower door frame locking members are integrally formed and are relatively large. However, in this locking device, the door frame locking members 161 and 162 are separately provided. In addition to being formed in a small size, the unlocking operation is performed in conjunction with the sliding rod 248 of the unlocking mechanism for the front door frame. For this reason, the locking device can be reduced in weight, and the structure can be remarkably simplified.

  25 and 28, a stopper 171 is provided below the engaging portion 248d of the sliding rod 248 so as to protrude toward the cam plate 8 side. The stopper 171 prevents the sliding rod 248 from sliding upward. Even when the sliding rod 248 moves illegally with a wire or the like in the locked state, the stoppers 171 shown in FIGS. The stopper 171 contacts the first engagement convex portion 8a of the cam plate 8 in the normal position, thereby preventing the sliding rod 248 and the rod members 4 and 5 from moving to the unlocked position.

  Next, a description will be given of the operational effects related to locking of the pachinko machine 10 of the present embodiment configured as described above.

  When the main body frame 12 in the pachinko machine 10 is closed with respect to the outer frame 11, as shown in FIG. 10, the upper and lower hook members 4 and 5 of the locking device independently resist the tensile force of the coil springs 9b and 9d. Then, it moves upward while hitting the receiving metal fittings 164 and 165 on the outer frame 11 side, and then returned by the tensile force of the coil springs 9b and 9d to be locked to the receiving metal fittings 164 and 165 to be locked (FIG. 2 dot-dash line at 30).

  When unlocking it, the cam plate 8 is rotated by turning the lock shaft of the cylinder lock 91 counterclockwise when viewed from the back surface with the key K inserted into the key hole of the cylinder lock 91. Then, the first engagement convex portion 8a of the cam plate 8 engages with the engagement portion 248d of the slide rod 248, and the slide rod 248 slides upward. Then, the upper and lower flange members 4 and 5 that are interlocked only when the sliding rod 248 is raised are moved upward, whereby the engagement of the outer frame 11 with the receiving brackets 164 and 165 is released, and the main body frame 12 can be opened. It becomes a state.

  On the other hand, when the front door frame 13 in the main body frame 12 is closed with respect to the main body frame 12, the door frame flange portions 155 and 156 protruding rearward of the front door frame 13 are inserted into the main body frame 12, as shown in FIG. After passing through the holes 87 and 88 (see FIG. 3), it enters into the base frame 247 from the insertion holes 158 and 159 formed in the mounting plate 2, and enters the locking holes 167 and 168 of the door frame locking members 161 and 162. enter. And after sliding the door frame locking members 161 and 162 against the tensile force of the coil springs 9a and 9c, the door frame locking members 161 and 162 are returned upward by the tensile force of the coil springs 9a and 9c. . As a result, the door frame flanges 155 and 156 are locked to the edges of the locking holes 167 and 168, and the front door frame 13 is locked.

  When unlocking the front door frame 13, when the key K is inserted into the key hole of the cylinder lock 91, the lock shaft of the cylinder lock 91 is turned clockwise as viewed from the back surface, and the cam plate 8 is rotated. 8 is engaged with the engagement portion 248c of the sliding rod 248, and the sliding rod 248 slides downward against the tensile force of the coil springs 9a, 9c. Then, the upper and lower door frame locking members 161 and 162 that are interlocked only when the sliding rod 248 slides downward slides downward, whereby the door frame flange portions 155 and 156 of the front door frame 13 and the locking holes are engaged. The edge portions of 167 and 168 are disengaged, and the front door frame 13 is opened.

  On the other hand, even when the wire or the like is inserted from the gap of the pachinko machine 10 in the locked state and is hooked on the hook member 4 or 5, and the hook member 4 or 5 is pulled upward, both the hook members 4, 5 Exist independently of each other, one of the flange members 4 or 5 moves upward, but the other flange member 5 or 4 does not move. For this reason, even if a fraudulent person moves one hook member 4 or 5 in the unlocking direction with a wire or the like, the locked state is held by the other hook member 5 or 4 to prevent unauthorized opening of the main body frame 12. Is done.

  Further, when an attempt is made to unlock the wire by hooking a wire or the like on the sliding rod 248 and sliding it upward, the stopper 171 provided on the cam plate 8 side of the sliding rod 248 is provided with the cam plate 8. When the first engaging projection 8a hits, the movement of the sliding rod 248 toward the unlocking side is prevented, and the unauthorized unlocking of the main body frame 12 is similarly prevented.

  Furthermore, since the door frame locking members 161 and 162 are also formed so as to be movable downward independently of the sliding rod 248, similarly to the case where the unlocking of the main body frame 12 is prevented, Unauthorized unlocking can be prevented.

  Next, with regard to the locking device described above, a more excellent configuration from the viewpoint of unauthorized unlocking, that is, a first example of a structure for preventing unauthorized unlocking will be described with reference to FIGS. 31 and 32. FIG. 31 is a perspective view showing the rear configuration of the main body frame 12 similar to FIG. 10 described above, and FIG. 32 is a right side view showing the use situation of the locking device similar to FIG. 30 described above. However, FIG. 31 and FIG. 32 differ from FIG. 10 and FIG. 30 in that a special configuration is provided in the main body frame 12 so that the mounting position of the locking device (mounting plate 2) is different.

  As shown in FIGS. 31 and 32, in order to move the position where the mounting plate 2 is installed to the part where the locking device of the main body frame 12 is attached, that is, the part where the mounting plate 2 of the base frame 247 is attached. The base portion 181 is provided. The pedestal 181 is formed to have substantially the same shape as the mounting plate 2 in the present embodiment. The back surface (mounting surface) of the pedestal portion 18 is rearward by a length D in the depth direction from the boundary position with the outer frame 11 when the main body frame 12 is closed with respect to the outer frame 11 due to the thickness of the pedestal portion 18. It is arranged at the position. Note that the shape of the pedestal portion 18 is not necessarily the same as that of the mounting plate 2, and may be any shape as long as it has a strength that can be stably fixed in a situation where the mounting plate 2 is disposed rearward. The number is arbitrary. The pedestal portion 18 may be formed integrally with the main body frame 12, may be prepared separately from the main body frame 12, and may be retrofitted, or further once attached to the main body frame 12 together with the mounting plate 2. It may be attached to.

  Now, by providing the pedestal 18 in the main body frame 12 in this way, the same effects as those described with reference to FIGS. 23 to 30 can be obtained, and as shown in FIG. In the state where the main body frame 12 is closed, when a wire or the like is inserted through a gap at the boundary position between the main body frame 12 and the outer frame 11 to perform unauthorized unlocking, the wire or the like is placed on the right side surface of the base portion 18. And the frame members 4 and 5 for unlocking the main body frame 12, the door frame locking members 161 and 162 for opening the front door frame 13, the frame members 4 and 5, and the door frame locking The sliding rod 248 for moving the members 161 and 162 cannot be reached. Therefore, unauthorized unlocking of the main body frame 12 and the front door frame 13 can be prevented in advance.

  In particular, when the pedestal portion 181 is not provided, a wire is inserted through the gap between the main body frame 12 and the outer frame 11 to move both the collar members 4 and 5 at a time, or both door frame locking members 161, It is theoretically possible to move 162 at a time. Of course, such fraud is very difficult. However, by providing the pedestal 181 as described above, even if the wire is inserted, the wire etc. is the hook members 4 and 5 and the door frame locking member. Since 161, 162 and the sliding rod 248 are not reached, unauthorized unlocking can be prevented almost certainly. In addition, since foreign matters such as wires do not reach the eave members 4 and 5, door frame locking members 161 and 162, sliding eaves 248, etc., they are also prevented from being damaged, which is excellent from the viewpoint of protecting the locking device. It will be. Further, when the pedestal portion 181 is provided, it is not always necessary to operate the eave members 4 and 5 independently or to operate the door frame locking members 161 and 162 independently. Even if a locking device is used, there is an advantage that unauthorized unlocking can be prevented.

  Next, a second example of an unauthorized unlocking prevention structure will be described with reference to FIGS. 33 is a perspective view of the front and rear of the blocking member 190, and FIGS. 34 to 36 are views corresponding to FIGS. 10, 29, and 30 described above, respectively, and the blocking member 190 is mounted. It shows the state.

  In the second example of the unauthorized unlocking prevention structure, the blocking member 190 shown in FIG. 33 is prepared as a separate body in the locking device described up to FIG. 30, and the blocking member 190 is shown in FIG. 34 to FIG. This is realized by retrofitting the machine 10.

  As shown in FIG. 33, in this embodiment, the blocking member 190 is integrally formed by bending and cutting a metal plate. The configuration of each part of the blocking member 190 will be described. The blocking member 190 includes a plate-shaped blocking wall portion 191 extending in the vertical direction, an upper piece 192 formed by bending the upper end of the blocking wall portion 191 in the horizontal direction, and an upper portion thereof. And a hanging piece 193 formed by bending the tip of the piece 192 downward. A pair of projecting pieces 194 extending to the back side are formed at an intermediate position of the blocking wall portion 191 so as to extend along the plate surface of the blocking wall portion 191 and have an upper piece 192 and a hanging piece 193. Projection pieces 195 and 196 extending inward are formed on the inner side. A support piece 197 extending in parallel with the upper piece 192 is formed on the back side of the lower end of the blocking wall 191, and a U-shaped recess 198 opening downward is formed on the support piece 197.

  The blocking member 190 configured in this manner is attached to the upper end of the locking device. That is, as shown in FIGS. 34 to 36, the plate surface of the upper piece 192 is disposed along the upper surface of the base frame 247, and the plate surface of the hanging piece 193 is the outer surface of the support piece 3 (right side surface of FIG. 35). It is arranged along. Then, the projecting piece 195 provided on the upper piece 192 and the projecting piece 196 of the hanging piece 193 are inserted into the gaps between the back surface of the mounting plate 2 and the main body frame 12, respectively. Further, as shown in FIG. 34, a large number of ribs 199 project from the back side of the main body frame 12, and the projecting pieces 194 of the blocking wall 191 are inserted into the recesses between the ribs 199. Further, the recess 198 of the support piece 197 is provided in correspondence with the screw hole 200 formed in the mounting plate 2, and when the mounting plate 2 of the blocking member 190 is fixed to the main body frame 12, The blocking member 190 is attached and fixed by being screwed into the main body frame 12 through the screw hole 200. The blocking member 190 is attached by inserting the projecting pieces 195 and 196 from above the base frame 247, then inserting the projecting piece 194 into the recess, and finally with the recess 198 corresponding to the screw hole 200. It is done in the order of stopping.

  And in the attachment state of the interruption | blocking member 190, the interruption | blocking wall part 191 will be arrange | positioned on the side opposite to the support plate 3 of the upper collar member 4 and the upper door frame locking member 161 of a locking device. . As a result, as shown in FIG. 34 to FIG. The wire or the like hits the blocking wall 191 when attempting to perform, and the upper brim member 4 for releasing the lock of the main body frame 12 or the upper door for opening the front door frame 13 The frame locking member 161 cannot be reached. Therefore, unauthorized unlocking of the main body frame 12 and the front door frame 13 can be prevented in advance.

  In particular, in the present embodiment, the upper and lower hook members 4 and 5 operate independently, and the upper and lower door frame locking members 161 and 162 operate independently, so that the upper hook member 4 and the door frame locking member It is only necessary to prevent fraud 161, and the blocking member 190 can be very small.

  In addition, since the blocking member 190 can be retrofitted to the pachinko machine 10, it can also be used for unauthorized unlocking performed by inserting a wire or the like into the existing pachinko machine from the gap at the boundary between the main body frame 12 and the outer frame 11. It is possible to take measures against it.

  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, and I / O when the power is shut down (including when a power failure occurs, the same applies hereinafter) when the power is shut down due to the occurrence of a power failure or the like. The area of the pachinko machine 10 can be restored to the state before the power cut-off based on the information in the backup area 503a when the power is turned on (including power-on due to power failure cancellation). Yes. Writing to the backup area 503a is executed when the power is shut off by the NMI interrupt process (see FIG. 48), and restoration of each value written in the backup area 503a is executed in the main process (see FIG. 41) 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 RAM 513 of the payout control device 311 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 313 even after the power of the pachinko machine 10 is shut off, like the RAM 503 of the main control device 271. The RAM 513 is provided with a backup area 513a in addition to a memory and an area for temporarily storing various data.

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

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

  The launch control device 312 permits or prohibits the launch of the game ball by the launch motor 229, and the launch motor 229 is permitted to drive when a predetermined condition is met. Specifically, it is detected by a sensor signal that a firing permission signal is output from the payout control device 311, a 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 variation display of the first symbol (special symbol) on the first symbol display device 41 and the variation display of the second symbol (ordinary symbol) on the second symbol display device 42. The display control device 214 includes a CPU 521, a ROM (program ROM) 522, a work RAM 523, a video RAM 524, a character ROM 525, an image controller 526, an input port 527, two output ports 528 and 529, and a bus line. 530 and 531. The input side of the input port 527 is connected to the output side of the main controller 271, and the output side of the input port 527 is connected to the CPU 521, ROM 522, work RAM 523, image controller 526, and output port via the bus line 530. 528 is connected. A second symbol display device 42 (display unit 45) and an audio lamp control device 272 are connected to the output side of the output port 528. Further, an output port 529 is connected to the image controller 526 via a bus line 531, and the first symbol display device 41 is connected to the output side of the output port 529.

  The CPU 521 of the display control device 214 controls the display of the first symbol display device 41 and the second symbol display device 42 based on the symbol display command transmitted from the main control device 271. The ROM 522 is a memory for storing various control programs executed by the CPU 521 and fixed value data, and the work RAM 523 is for temporarily storing work data and flags used when the CPU 521 executes various programs. Memory.

  The video RAM 524 is a memory for storing display data displayed on the first symbol display device 41, and the display content of the first symbol display device 41 is changed by rewriting the contents of the video RAM 524. The character ROM 525 is a memory for storing character data such as symbols displayed on the first symbol display device 41. The image controller 526 adjusts the timings of the CPU 521, the video RAM 524, and the output port 529 to intervene in reading and writing data, and also reads display data stored in the video RAM 524 from the character ROM 525 at a predetermined timing. It is displayed on the symbol display device 41.

  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 operation 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, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. The power failure signal SG1 is output to the main controller 271 and the payout controller 311. By 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. 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 respective backup areas 503a and 513a is cleared in the main controller 271 and the payout controller 311.

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

  In the first symbol display device, three symbol sequences of left, middle, and right are set. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-symbol made of, for example, a diamond-shaped picture. Each main symbol and sub-design constitute a first 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 first symbols of 10 main symbols and 10 sub symbols. On the first symbol display device 41, 20 first symbols for each symbol row are variably displayed so as to scroll from top to bottom with periodicity. In particular, the numbers of the main symbols appear in descending order in the left symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the right symbol row. The first symbol display device 41 is configured to display first, middle, and lower three first symbols for each symbol row. Accordingly, the first symbol display device 41 displays a total of nine first symbols of 3 rows × 3 columns. In the first symbol display device 41, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set. Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, it is a combination of jackpot symbols on any active line (in this embodiment, the same main symbol combination) If you arrange it, a big hit video will be displayed as a big hit.

  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 of symbol display of the first symbol display device 41, and the like. Specifically, As shown in FIG. 40, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 41, and the first symbol display device 41 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the first symbol display device 41, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is 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). The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in time series in accordance with the winning history.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. Note that the random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interrupt 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 operating port 33. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”. The high probability means a state in which the combination of the first symbol is a big hit by a predetermined combination of probability variation symbols, and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state.

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

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 41, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 33.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented one by one within a range of 0 to 240 and reaches 0 after reaching the maximum value (that is, 240). In the following description, CS1 is also referred to as “first variation type counter” and CS2 is also referred to as “second variation type counter”. The first variation type counter CS1 determines the reach type of the first symbol, such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes. The second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the first symbol display device 41 starts the variation of the first symbol.

  The left, middle and right off symbol counters CL, CM, CR determine the stop symbol of the left row 1 symbol, the middle row 1 symbol, and the right row 1 symbol when the big hit lottery is missed. In each column, any one of the 20 first symbols is displayed in combination with the main symbol and the sub symbol, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle and lower symbols are determined by the out symbol counter CL, the upper, middle and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The top, middle and bottom symbols are determined.

  In the present embodiment, the values of the counters CL, CM, and CR are randomly updated by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the value of the lower 3 bits of the R register is added to the previous value, and when the addition result exceeds the maximum value, 20 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated in the normal process so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach other than the front / rear symbol buffer of the RAM 503, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the start of variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier and the completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second symbol random number counter C4 is used for the lottery of the second symbol display device 42. The second symbol random number counter C4 is configured, 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 C4 is updated periodically (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. 46 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. 46, in step S601, various winning switch reading processes are executed. That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 271 is read, and the state of the switch is determined and the detection information (winning detection information) is stored.

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

  Thereafter, in step S604, a start winning process associated with winning in the operating port 33 is executed. The start winning process will be described with reference to the flowchart of FIG. 47. In step S701, whether or not the game ball has won a prize (start prize) is determined based on the detection information of the operating port switch 224. If it is determined that the game ball has won the operation port 33, in the subsequent step S702, it is determined whether or not the number N of operation reservation balls of the first symbol display device 41 is less than the upper limit value (4 in the present embodiment). Determine. The process proceeds to step S703 on the condition that there is a winning at the operation port 33 and the number N of activated balls is <4, and the number N of activated balls is incremented by one. In the subsequent step S704, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in the step S603 are stored in the first area of the free storage area of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interrupt process.

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

  FIG. 48 is a flowchart showing the NMI interrupt process. This process is executed by the CPU 501 of the main controller 271 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 271 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG2 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. 48 is stored in the ROM 502 of the main controller 271. For a predetermined time after the power failure signal SG2 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 271 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing, in step S801, the used register is saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the power-off occurrence information is set in the backup area 503a, and in step S804, a power-off notification command indicating that the power has been cut off is transmitted to another control device. In step S805, a RAM determination value is calculated and stored in the backup area 503a. The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. In step S806, RAM access is prohibited. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed.

  The above NMI interrupt processing is similarly executed 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 513 a 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 SG2 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 SG2 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. 48 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 41 is a flowchart showing an example of a main process executed by the CPU 501 in the main controller 271. This main process is started upon a reset when the power is turned on.

  In the main process, in step S101, an initial setting process associated with power-on is executed. Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (audio lamp control device 272, payout control device 311, etc.) to become operable, for example, Wait processing is performed for about 1 second. In step S102, a payout permission command is transmitted to the payout control device 311. 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, for example, a checksum value at the work area address of the RAM 503. Note that it is possible to determine the effectiveness of backup based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

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

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

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

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

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

  The update process of each outlier symbol counter CL, CM, CR will be described. As shown in FIG. 43, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. It is determined whether or not it is time to update the symbol counter CM symbol symbol CM. If the update timing of the left symbol row (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol row is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Further, if the update timing of the right symbol sequence (both NO in steps S301 and S302), the process proceeds to step S305, and the outlier symbol counter CR of the right symbol sequence is updated. In updating the outlier symbol counters CL, CM, CR in steps S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is subtracted when the addition result exceeds the maximum value, The result of the calculation is out of sync and is used as the current value of the symbol counters CL, CM, CR. According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, in step S306, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination. If the symbol combination is a jackpot symbol combination, the process is terminated. If it is not a jackpot symbol combination, it is determined in step S07 whether or not it is a reach symbol combination, and if it is a reach symbol combination, in step S308 it is further determined whether or not it is an out-of-front / reach reach. To do. If the off symbol counters CL, CM, and CR are combinations of front and rear outreach, the process proceeds to step S309, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear outreach symbol buffer of the RAM 503. If the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step S310, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. . If the combination of outlier symbol counters CL, CM, CR is not a jackpot symbol combination and not a reach symbol combination (when both steps S306 and S307 are NO), this is a combination of outlier symbol counters CL, CM, CR In this case, the process proceeds to step S 311, and the combination of the off symbol counters CL, CM, and CR at that time is stored in the complete off symbol buffer of the RAM 503.

  After update processing of the off symbol counters CL, CM, and CR, in step S204 in FIG. 42, a prize ball counting signal and a payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 41 is executed. By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

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

  In step S207, display control of the second symbol (for example, a normal symbol of “◯” or “x”) by the second symbol display device 42 is executed. Briefly, on the condition that the game ball has passed through the through gate 34, the value of the second symbol random number counter C4 is acquired and the second symbol is displayed on the display unit 45 of the second symbol display device 42. Is displayed. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the operating port 33 is released for a predetermined time. Although not described, the second symbol random number counter C4 is also updated by the timer interrupt process shown in FIG. 46, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3.

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

  Here, since the execution time of each process of steps S201 to S207 changes according to the state of the game, the remaining time until the next normal process execution timing 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 big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The variation type counters CS1 and CS2 can also be updated at random.

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

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

  If neither the big hit or the change in the first symbol is being displayed and if the number N of activated balls is> 0, the process proceeds to step S404. In step S404, 1 is subtracted from the number N of active suspension balls. In step S405, a process for shifting the data stored in the reserved ball storage area is executed. This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area.

  Thereafter, in step S406, the first symbol variation start process is executed. Here, the details of the variation start process will be described with reference to the flowchart of FIG. 45. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Whether or not the jackpot is determined is based on the relationship between the jackpot random number counter value and the mode at that time. As described above, “337,673” is a winning value among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, and “67, 131, 199, 269, 337, 401, 463, 523” at the high probability. “601, 661” is the winning value.

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

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

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

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

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

  If it is neither big hit nor reach, the process proceeds to step S510, and the left, middle, and right off symbol counters CL, CM, and CR stored in the complete off symbol buffer of the RAM 503 are set as stop symbol commands. In step S511, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command. At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 503, as in step S503 and the like. As described above, when the setting of the symbol stop command and the variation pattern command is completed at the time of jackpot, when the reach occurs, or when the reach does not occur, this processing is terminated.

  Returning to the description of FIG. 44, if step S402 is YES, that is, if the variation of the first symbol is being displayed, the process proceeds to step S407 to determine whether or not the variation time has elapsed. At this time, the variation time of the first symbol is determined according to the variation pattern of the first symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a confirmation command set for confirming the stop symbol is set, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 49 is a flowchart showing the main process of the payout control apparatus 311. This main process is started upon reset when the power is turned on.

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

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

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

  On the other hand, if the RAM erase switch 323 has not been pressed, the power-off occurrence information is set, and the RAM judgment value (checksum value, etc.) is normal, the condition at the time of power recovery Execute the process (process when the power supply is restored). That is, in step S909, the stack pointer prior to power shutdown is restored, and in step S910, 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. 50, in step S1001, a command from the main controller 271 is acquired, and the total number of prize balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

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

  Thereafter, in step S1006, the presence / absence of a state to be notified is determined.

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not paid out and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009, and the 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 state return switch 321 is checked to execute the ball removal process by driving the payout motor 358a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In subsequent step S1014, control of vibrator 360 (vibration motor control) is executed on condition that the ball is clogged. Thereafter, the process returns to the top of the payout control process.

  Here, in the winning ball control process shown in FIG. 51, in step S1101, the payout motor 358a is driven to execute payout of the winning ball. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, the payout motor 358a is driven to execute a retry process, and a stop process of the payout motor 358a is executed. Thereafter, the process returns to the payout control process in FIG.

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

  Further, if the game ball count is normal, the process proceeds to step S1106, and it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout has been completed. If the payout has been completed, 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. 52, in step S1201, the payout motor 358a is driven to pay out the lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

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

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

  According to the present embodiment described in detail above, the main body frame 12 and the outer frame can be provided in a state in which the main body frame 12 is closed with respect to the outer frame 11 by providing the pedestal portion 18 to which the mounting plate 2 of the locking device is attached. 11, when a wire or the like is inserted through a gap between the boundary position with the wire 11 and an unauthorized unlocking is attempted, the wire or the like hits the right side surface of the pedestal portion 18, and a hook for unlocking the main body frame 12. The members 4 and 5 and the door frame locking members 10 and 11 for opening the front door frame 13 and the sliding rod 248 for moving the rod members 4 and 5 and the door frame locking members 10 and 11 are reached. Can not. Therefore, unauthorized unlocking of the main body frame 12 and the front door frame 13 can be prevented in advance. Further, since foreign matters such as wires do not reach the eave members 4 and 5, the door frame locking members 10 and 11, the sliding eaves 248, etc., they are also prevented from being damaged, which is excellent from the viewpoint of protecting the locking device. It will be. Further, when the pedestal portion 181 is provided, it is not always necessary to operate the eave members 4 and 5 independently or to operate the door frame locking members 10 and 11 independently. Even if a locking device is used, there is an advantage that unauthorized unlocking can be prevented.

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

  (A) As a second example of the structure for preventing unauthorized unlocking, the blocking member 190 may be configured as shown in FIG. 37A is a perspective view of the blocking member 190 corresponding to FIG. 33B, and FIG. 37B is a cross-sectional view taken along line XX of FIG. The blocking member 190 shown in FIG. 37 is different from that described above in that a bent piece 187 is formed that is bent along the side portion of the blocking wall 191. Accordingly, when the blocking member 190 is attached, the bent piece 187 is bent so as to incline toward the fixed end side of the main body frame 12. In addition, it is difficult to catch the wire between the main body frame 12 and the outer frame 11 due to fraud.

  (B) Although the blocking member 190 in the second example of the unauthorized unlocking prevention structure is integrally formed by bending and cutting a metal plate, a plurality of members may be connected or synthesized other than metal. You may form by a resin material etc.

  (C) In the second example of the structure for preventing unauthorized unlocking, the upper and lower hook members 4 and 5 operate independently, and the lock of the main body frame 12 cannot be unlocked unless both hook members 4 and 5 are released simultaneously. Since the upper and lower door frame locking members 161 and 162 operate independently and both locking members 161 and 162 are not released at the same time, the front door frame 13 cannot be unlocked. No. 4 and the door frame locking member 161 were taken. On the other hand, the blocking member 190 may be arranged at the lower part of the locking device so as to take measures only for the lower flange member 5 and the lower door frame locking member 162.

  (D) In the second example of the structure for preventing unauthorized unlocking, in addition to the blocking member 190 taking measures against the upper flange member 4 and the door frame locking member 161, the lower flange member 5 and the lower door frame locking member 162 are provided. You may make it take measures about. Specifically, a pair of upper and lower blocking members 190 can be provided. In addition to providing a pair of upper and lower blocking members 190, the blocking member 190 is extended to the same height as the vertical length of the base frame 247, and the upper and lower both-side members 4 and 5 and the upper and lower doors are formed by one blocking member 190. The frame locking members 161 and 162 may be prevented from being illegally unlocked. In this manner, the main body frame 12 and the outer frame can be obtained even in the conventional type of locking device in which the upper and lower both-side flange members 4 and 5 do not operate independently and the upper and lower door frame locking members 161 and 162 do not operate independently. Unauthorized unlocking from between 11 and 11 can be prevented beforehand.

  (E) In the second structure for preventing unauthorized unlocking, the blocking member 190 is attached to the main body frame 12 by using a screw for attaching the base frame 247 (attachment plate 2). It may be. Further, when there is no reason for retrofitting the blocking member 190 to an existing pachinko machine, the blocking member 190 may be integrally provided on a part of the base frame 247.

  (F) It is also possible to combine the second unauthorized unlocking prevention structure example provided with the blocking member 190 and the first unauthorized unlocking prevention structure example provided with the base 181. This is useful for preventing further unauthorized unlocking.

  (G) In the first example of the unauthorized unlocking prevention structure, in order to prevent unauthorized unlocking of the main body frame 12 and the front door frame 13, a base portion 181 for offsetting the base frame 247 (mounting plate 2) rearward. However, a recess such as a groove that opens toward the gap between the main body frame 12 and the outer frame 11 is formed near the boundary position between the main body frame 12 and the outer frame 11 of the pedestal portion 181. Also good. Due to the presence of such a recess, even if a wire or the like is inserted for unauthorized unlocking from the gap between the main body frame 12 and the outer frame 11, the tip of the wire or the like enters the recess and bypasses from there. The possibility that a wire or the like may enter the base frame 247 side can be avoided.

  (H) In the first example of the structure for preventing unauthorized unlocking, in order to prevent unauthorized unlocking of the main body frame 12 and the front door frame 13, a base 181 for offsetting the base frame 247 (mounting plate 2) rearward. However, a plurality of bosses for fixing the mounting plate 2 to the main body frame 12 at various places are extended to the rear, and the base frame 247 (mounting plate 2) is offset rearward depending on the height of the boss. May be.

  (I) In the first example of the structure for preventing unauthorized unlocking, a base 181 for offsetting the base frame 247 (mounting plate 2) rearward in order to prevent unauthorized unlocking of the main body frame 12 and the front door frame 13. However, instead of this, or in addition to this, a protective wall for preventing the entry of a wire or the like may be provided closer to the open end than the base frame 247 of the main body frame 12. In this case, a space for providing a defense wall is required on the open end side (right side when viewed from the front) with respect to the base frame 247. As a simple alternative to such a defense wall, the open end side of the mounting plate 2 can be configured to be bent backward, and the bent portion can have a function of a defense wall. Care must be taken because the wall height tends to be insufficient.

  (J) 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, other types of pachinko machines different from the above embodiment, for example, pachinko machines without the variable display unit 35, pachinko machines with other accessories, arrange ball machines, sparrow balls, and other gaming machines Is also applicable. It can also be applied to slot machines and the like. Slot machines generally have an outer shell formed from a housing (game machine body) containing a reel, a hopper, and a control device, and a front panel (opening / closing member) that covers the front of the housing. However, if the locking device and the related configuration described above are applied, it is possible to prevent the front panel from being illegally unlocked with respect to the housing.
