  Hereinafter, an embodiment of a pachinko gaming machine (hereinafter simply referred to as “pachinko machine”) will be described in detail with reference to the drawings. FIG. 1 is a front view of the pachinko machine 10, and FIG. 2 (a) is a perspective view showing a state in which an inner frame 12 and a front frame set 14 are opened with respect to an outer frame 11 described later. FIG. 2B is a perspective view showing a part of the lower dish unit 13 when viewed in the direction of the arrow Va in FIG.

  As shown in FIGS. 1 and 2, the pachinko machine 10 includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is supported on one side of the outer frame 11 so that the inner frame 12 can be opened and closed. Has been. The outer frame 11 is formed in a rectangular shape as a whole by a wooden plate material, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, compared with the conventional structure which assembled | attached each board | plate material using the nail and the rivet, the reuse of a structural member is made easy. In the present embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left and right direction is 518 mm (inner dimension 480 mm). In addition, you may make it comprise the outer frame 11 with light metals, such as resin and aluminum.

  The inner frame 12 is made of a synthetic resin, specifically, ABS (acrylonitrile butadiene styrene) resin. ABS resin is suitable as a constituent material of the inner frame 12 because it has a low material cost, has a good paste such as plating, has a good decorative property, and has a high impact resistance. The opening / closing axis of the inner frame 12 extends vertically from the front of the pachinko machine 10 to the opposite side of the place where the game ball launching handle 18 is installed, and the inner frame 12 is directed forward with the opening / closing axis as the axis. It can be opened. Since the opening / closing axis is provided on the opposite side of the game ball launching handle 18, the inner frame 12 can be greatly opened. Normally, in the pachinko hall, the pachinko machines 10 are arranged adjacent to each other. Therefore, when the opening / closing axis is provided on the game ball launching handle 18 side, the game ball launching handle 18 that is opened together with the inner frame 12 is opened. This is because the amount of opening is reduced due to contact.

  A lower tray unit 13 is attached to the inner frame 12 at the lowermost portion, and a front frame set 14 is attached so as to cover the inner frame 12 in a range excluding the lower tray unit 13. The front frame set 14 is attached to the inner frame 12 so as to be openable and closable. Like the inner frame 12, the front frame set 14 can be opened forward with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10. It is like that. An outer peripheral wall projecting toward the front side is formed on the outer periphery of the inner frame 12, and a front frame set 14 is disposed inside the outer peripheral wall. That is, when the front frame set 14 is attached to the inner frame 12, the outer periphery of the side surface of the front frame set 14 is surrounded by the outer peripheral wall of the inner frame 12. It is possible to suppress illegal acts by making it difficult to insert a wire or the like. Further, a front frame collar member 412 for closing and locking the front frame set 14 is provided at two locations on the right and left sides when viewed from the front of the inner frame 12, and the front frame is disposed on the back side of the front frame set 14. A receiving metal fitting 402 that engages with the barbed member 412 is provided. The locking of the front frame set 14 by the front frame collar member 412 and the receiving metal fitting 402 will be described later with reference to FIG.

  Similar to the front frame set 14, the lower dish unit 13 is attached to the inner frame 12 so as to be openable and closable, and is arranged so as to cover the inner frame 12 along the lower side of the front frame set 14. Similarly to the inner frame 12 and the front frame set 14, the lower dish unit 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. The upper end portion of the lower plate unit 13 is provided with a protruding portion 13a that is located on the back side of the front frame set 14 and partially overlaps when the lower plate unit 13 and the front frame set 14 are closed. If the set 14 is not opened, the lower plate unit 13 cannot be opened. In addition, a lower plate frame collar member 413 for closing and locking the lower plate unit 13 is provided on the lower right side when viewed from the front of the inner frame 12, and FIG. As shown in b), a receiving metal fitting 403 that engages with the lower plate ridge member 413 is provided. The locking of the front frame set 14 by the lower plate cage member 413 and the receiving metal fitting 403 will also be described later with reference to FIG.

  A volume adjustment substrate 271 having a switch for adjusting the volume output from the speaker on the left side when viewed from the front is provided at the lower part of the inner frame 12 covered with the lower dish unit 13. In general, the volume control switch is provided on the back side of the inner frame 12, and the volume cannot be adjusted unless the operator opens the inner frame 12, but in the pachinko machine 10, the part covered by the lower dish unit 13. Since the switch for adjusting the volume is provided in the operator, the operator can easily adjust the volume simply by opening the lower tray unit 13.

  A laterally long rectangular wiring hole 272 is formed in the lower right end of the inner frame 12, and wiring connected to a speaker or the like provided in the lower dish unit 13 is connected to the back side of the inner frame 12 through the wiring hole 272. Connected to the sound lamp control board. In addition, on the lower right side of the lower tray unit 13, a launching solenoid 229 for launching a game ball is disposed. In the pachinko machine 10, the firing solenoid 229 is disposed so as to overlap the lower dish unit 13 when viewed from the front. Even if the position of the firing solenoid 229 is arranged close to the lower side of the front view of the pachinko machine 10, by opening the lower pan unit 13, it is possible to facilitate the work at the time of failure or inspection. Therefore, it is possible to improve the workability of the inspection with respect to the game ball launching device while arranging the device necessary for game ball launching on the lower side and expanding the game area related to the game formed on the upper side. it can.

  On the upper part of the inner frame 12, a push button type opening / closing switch 25 protruding in a columnar shape is provided. The open / close switch 25 is a switch for detecting the open / closed state of the front frame set 14. When the front frame set 14 is closed with respect to the inner frame 12, the open / close switch 25 is pressed, and conversely, when the front frame set 14 is open with respect to the inner frame 12, the open / close switch 25. Is in a non-pressing protruding state and detects the open / closed state of the front frame set 14. A wiring hole 26 is formed in the upper left portion of the inner frame 12 (see FIG. 2). The wiring hole 26 is a hole for wiring the wiring of the front frame set 14 through the inner frame 12 to the back surface of the game board 30. R is formed at the corner of the wiring hole 26 so that each cord wired in the wiring hole 26 is not damaged at the corner. As shown in FIG. 4, a wiring hole 37 is also formed in the upper left part of the game board 30 corresponding to the wiring hole 26.

  FIG. 3 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10. In FIG. 3, for the sake of convenience, the configuration in the game area on the surface of the game board 30 is shown as blank. As shown in FIG. 3, the lower tray unit 13 is provided with a lower tray 15 as a ball receiving tray at a substantially central portion so that game balls discharged from the outlet 16 can be stored in the lower tray 15. Yes. Similar to the inner frame 12, the lower plate 15 is formed of flame retardant ABS resin. It is not always necessary to form all of the lower plate 15 with ABS resin, but at least the surface portion of the lower plate 15, that is, the surface layer of the lower plate 15 and the front panel behind the lower plate 15 are formed with ABS resin. It is preferable. Since there is a danger that the lit cigarette will be left in the lower plate 15, it is possible to prevent damage to the pachinko machine 10 and the occurrence of fire by forming at least the surface portion thereof with flame retardant ABS resin. It is. The front panel has a large number of speaker holes 24 for outputting sound from the speakers.

  In the lower part of the front of the lower plate 15, a ball removal lever 17 is provided for operating when the game balls stored in the lower plate 15 are discharged downward. The ball release lever 17 is always urged to the right, and by sliding it to the left against the urge, the bottom opening formed on the bottom surface of the lower plate 15 opens, A game ball naturally falls from the bottom opening and is discharged. The operation of the ball pulling lever 17 is usually performed in a state where a box (generally referred to as “thousand box”) for receiving game balls discharged from the lower plate 15 is placed below the lower plate 15. In addition, a game ball launching handle 18 is disposed on the right side of the lower plate 15 in a state of protruding from the lower plate unit 13 toward the front side, and an ashtray is mounted in a cantilevered manner on the left side of the lower plate 15. It is worn. The ashtray is rotatable in the front and back directions together with a shaft rotatably attached to the lower plate 15. Thus, by arranging the game ball launch handle 18 on one side of the lower plate 15 and the ashtray on the other side, the decorativeness of the pachinko machine 10 is improved while maintaining the aesthetic balance of the left and right of the lower plate unit 13. ing.

  On the other hand, as shown in FIG. 1, the front frame set 14 above the lower plate 15 is integrally provided with an upper plate 19 as a ball receiving plate. Here, the upper plate 19 is for temporarily storing the game balls and guiding them to the game ball launching device while aligning them in a line. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame set, and an upper plate is provided on the front decorative frame, but in this embodiment, the front decorative frame is omitted. The upper plate 19 is provided directly on the front frame set 14. This is because the front frame set 14 of the present embodiment includes a window portion 101 that is largely cut out in a substantially elliptical shape so that a game area formed larger than a conventional pachinko machine can be viewed from the outside. Therefore, in order to improve the strength of the front frame set 14 as much as possible, the upper plate 19 is integrally formed with the front frame set 14. Similar to the lower plate 15, the upper plate 19 has at least a surface layer formed of a flame-retardant ABS resin. Note that how the game area is formed larger than that of a conventional pachinko machine will be described later.

The game board 30 is composed of a rectangular plywood and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 20 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 30 is exposed to the front surface side of the inner frame 12 through the window hole 21 of the resin base 20. The vertical length of the game board 30 is 476 mm, and the horizontal length is 452 mm (same size as before). That is, the game board 30 is formed in the same size as the conventional pachinko machine, and the game area is formed larger than the conventional pachinko machine.

  Next, the configuration of the game board 30 will be described with reference to FIG. In the game board 30, a general winning port 31, a variable winning device 32, a large port (starting port) 33, a small gate (through gate) 34, a variable display unit 35, etc. are arranged in a through hole formed by router processing. It is attached from the front side of the game board 30 with wood screws or the like. As is well known, when a game ball enters the general winning port 31, the variable winning device 32, and the big game port 33 and a predetermined output is output from a detection switch described later, a predetermined number is supplied to the upper plate 19 (or the lower plate 15). The prize balls will be paid out. In addition, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like are guided through the out port 36 to a ball discharge path (not shown). The game board 30 is provided with a large number of nails for appropriately dispersing and adjusting the falling direction of the game balls, and various members (acts) such as a windmill.

  The variable display device unit 35 includes a small symbol display device 41 that variably displays small symbols (ordinary symbols) triggered by the passage of a game ball through the small gate 34, and a big symbol symbol triggered by winning a game ball at the big mouth 33. There is provided a large symbol display device 42 as a symbol display device for variably displaying (special symbols). The accessory symbol display device 41 includes an accessory symbol display unit 43 and a holding lamp 44. Each time a game ball passes through the accessory gate 34, the display symbol (the accessory symbol) fluctuates in the display unit 43. When the variable display stops at a predetermined symbol, the big mouth 33 is configured to be activated (opened) for a predetermined time. The number of times that the game ball passes through the accessory gate 34 is held up to a maximum of four times, and the number of times of holding is displayed on the hold lamp 44. Note that the small symbol display is changed by switching the lighting of a plurality of lamps on the display unit 43 as in the present embodiment, and a part of the large symbol display device 42 (liquid crystal display device) is used. May be performed. Similarly, the hold lamp 44 may be turned on by a part of the large symbol display device 42.

  The large symbol display device 42 is composed of a liquid crystal display device, and the display content is controlled by a display control device 45 described later. The large symbol display device 42 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are scrolled vertically for each symbol row and are variably displayed on the large symbol display device 42. In the present embodiment, the large symbol display device 42 is constituted by a large liquid crystal display of 8 inch size, and the variable display device unit 35 is provided with a center frame 47 so as to surround the large symbol display device 42. Has been.

  The variable winning device 32 is provided with a large winning opening formed in a horizontally long rectangular shape at the center thereof. The big winning opening is normally in a closed state where the game ball cannot be won or difficult to win, and the open state in which the game ball is likely to win in the case of a big win and the closed state in the normal state alternately Operates to repeat. Specifically, when a game ball wins in the big game mouth 33, the special game is based on the requirement that the symbols are variably displayed on the big game symbol display device 42, and the confirmed symbols after the stop are a combination of specific symbols set in advance. A condition occurs. When the special gaming state occurs, the large winning opening of the variable winning device 32 is configured to be in a state where the game ball is likely to win, that is, a predetermined open state. Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the large winning opening of the variable winning device 32 is repeatedly opened a predetermined number of times (becomes open).

  The number of times that the game ball has passed through the big mouth 33 is held up to a maximum of 4 times, and the number of times that the game ball is held is displayed on the hold lamp 46. The reserve lamps 46 are provided for the maximum number of reserves, and are arranged above the large symbol display device 42 in a well-balanced manner. Note that the hold lamp 46 may be deleted and turned on by a part of the large symbol display device 42.

  The game board 30 is provided with a rail unit 50 for guiding the game ball launched from the game ball launching device to the upper part of the game board 30 and is fired as the game ball launching handle 18 is rotated. The game balls are guided to the game area through the rail unit 50. The rail unit 50 is formed of a resin molded product having a ring shape, and includes an inner rail portion 51 and an outer rail mounting portion 52 that are integrally formed in an inner and outer double. The inner rail portion 51 is formed in a substantially annular shape except for about ¼ of the upper portion, and the outer rail mounting portion 52 has a part (mainly the left side portion) facing the inner rail portion 51. Is formed. The inner rail portion 51 and the outer rail mounting portion 52 constitute a guide rail, and the inner rail portion 51 and the outer rail mounting portion 52 are parallel to each other with a predetermined interval (the left portion toward the game). A ball guide passage for guiding the ball to the game area is formed. The ball guide passage is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip of the inner rail portion 51 (the upper left portion in FIG. 4). This prevents a situation in which the game ball once guided from the ball guide passage between the inner rail portion 51 and the outer rail attachment portion 52 to the upper portion of the game board 30 returns to the ball guide passage again.

  A return rubber 54 is attached to the outer rail mounting portion 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 4: a portion corresponding to the tip portion of the outer rail mounting portion 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back with the momentum attenuated. A sliding plate 55 as a long stainless steel metal strip is attached to the inner side surface of the outer rail mounting portion 52 in order to make the flight of the game ball smoother.

  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. Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially linear shape (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50 so that the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area on the game board 30 can be expanded. ing.

  A convex portion 57 is formed at the entrance of the ball guide passage between the inner rail portion 51 and the outer rail mounting portion 52 so as to close a part of the ball guide passage. The convex portion 57 is provided in a substantially vertical direction from the inner rail portion 51 to the lower end portion of the rail unit 50, and a foul ball that flows backward in the ball guide passage without reaching the game area is a foul ball passage 63 (see FIG. 3). It is to lead to. Note that the lower right corner and the lower left corner of the game board 30 are provided with adhering spaces K1, K2 for adhering seals and plates such as stamps and the like to secure the adhering spaces K1, K2. In addition, notches 58 and 59 are formed in the flange 56. As described above, since the game board 30 is provided with the adhering spaces K1, K2 such as a certificate, the game board 30 can be uniquely specified by directly attaching the certificate to the game board 30. it can. That is, it is possible to easily find an illegal exchange of game boards.

  In conventional pachinko machines, the rail is driven directly into the game board. However, as described above, in the pachinko machine 10 according to the present embodiment, the rail unit 50 is fastened to the game board 30 with screws or the like inserted through the flange 56. That is, in this embodiment, the game board 30 is formed in the same size as the conventional pachinko machine, and the game area is formed larger than the conventional pachinko machine, so the rail cannot be driven directly into the game board. The rail unit 50 is integrally formed with resin together with the flange 56, and the flange 56 is fastened to the game board 30 with screws or the like. According to the present embodiment employing such a configuration, the rail unit 50 can be easily detached from the game board 30 at the time of disposal, and therefore the rail unit 50 that is resin-molded can be easily recycled. In order to stably launch the game ball, the rail unit 50 on the game ball launch side is more firmly fixed than the other rail unit 50 with more screws. As the resin material constituting the rail unit 50, a fluorine-containing polycarbonate having a low frictional resistance is suitable.

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape on the inner periphery of the rail unit 50. 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. ing. In the present embodiment, the distance from the uppermost point of the outer rail mounting portion 52 to the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and the inner rail portion 51 extends from the extreme left position of the outer rail mounting portion 52. The distance to the extreme right position is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail portion 51 to the extreme right position of the inner rail portion 51 is 418 mm.

  In the present embodiment, the game area is a parallel part of the inner rail part 51 and the outer rail attachment part 52 in the area surrounded by the inner rail part 51 and the outer rail attachment part 52 when viewed from the front of the pachinko machine 10. The area excluding the area of a certain guide rail. Accordingly, since the game area does not include the guide rail portion, the left limit position toward the game area is specified not by the outer rail mounting portion 52 but by the inner rail portion 51. Similarly, 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. Further, the upper limit position of the game area is specified by the outer rail mounting 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 desirably at least 380 mm. More preferably, it is 390 mm or more, 400 mm or more, 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and further 460 mm or more. Of course, it may be 470 mm or more. That is, the width of the game area is preferably as large as possible from the viewpoint of expanding the game area. The height of the game area is preferably at least 400 mm. More preferably, it is 410 mm or more, 420 mm or more, 430 mm or more, 440 mm or more, 450 mm or more, and more preferably 460 mm or more. Of course, it is good also as 470 mm or more, 480 mm or more, and 490 mm or more. That is, the height of the game area is preferably as large as possible from the viewpoint of expanding the game area. In addition, about the combination of the said width | variety and height, it is good also as what combined the said numerical value arbitrarily.

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

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

  The accessory gates 34 located on both sides of the variable display device unit 35 have a guide mechanism that allows the game balls that have passed through the accessory gate 34 to be moved toward the center of the game area. As a result, even in a configuration in which the game area is expanded in the left-right direction, the game ball can be guided toward the big game mouth 33 and the variable winning device 32 in the center of the game area, and as a result, the game area is expanded. It is possible to suppress a decrease in interest due to difficulty in winning a game ball. Furthermore, since the game area is expanded in the left-right direction, a windmill, a small gate 34, a plurality of nails (guide nails for guiding the game ball to the center), and other accessories can be arranged. The behavior of the game ball in the game areas on the left and right sides of the variable display device unit 35 can be made more interesting. Further, since the game area is also expanded in the vertical direction, various windmills, accessory gates 34, a plurality of nails, and other accessories can be arranged, and the behavior of the game balls in the vertical direction in the game area. Can be made even more interesting.

  Returning to FIG. In the resin base 20, a launch rail 61 for guiding a game ball immediately after being launched from the game ball launcher is attached below the window hole 21 (below the game board 30). The firing rail 61 is fixedly attached to the resin base 20 via a metal plate 62 behind the firing rail 61, and is configured to extend linearly at a predetermined firing angle (launch angle). Accordingly, the game ball 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 of the rail unit 50 as described above. Is done.

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

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

  When the foul sphere flows backward in the guide rail, most of the foul sphere flows along the outer rail mounting portion 52 and drops downward when reaching the lower end of the outer rail mounting portion 52. May be ramped in the guide rail and jump to the inner rail 51 side. The foul ball that has jumped up hits the convex portion 57 at the entrance of the ball guide passage and is guided to the foul ball passage 63. Thereby, all of the foul balls are surely guided to the foul ball passage 63. Therefore, it is possible to suppress interference between the foul ball and the next-launched game ball.

  Although detailed disclosure of the drawings is omitted, one game ball is supplied to the game ball launching device one by one from the ball outlet on the front frame set 14 side (ball outlet leading from the most downstream portion of the upper plate 19). At this time, since the launch position of the game ball is lowered in the present embodiment, the drop from the exit of the ball on the front frame set 14 side to the launch position becomes large, but in the vicinity of the base end portion of the launch rail 61, its right side and Since the guide members 65 and 66 are installed on the front side, the game ball supplied from the ball outlet on the front frame set 14 side is always set at a predetermined launch position, and a stable launch operation can be realized.

  Further, the game ball launching device is provided with a hitting ball basket, and is configured such that the hit ball basket slides by the operation of a launching solenoid 229 constituting the game ball launching device. A game ball is fired as the hitting ball slides. Since it is desired to reduce the weight of the hitting ball, the weight of the hitting ball is reduced by changing the material to a light metal such as aluminum or reducing the size of the shaft portion. Note that it is not always necessary to slide the hitting ball by the solenoid to cause the game ball to be fired. good.

  The discharge port 67 communicates with the upper plate 19, and the game ball is discharged (dispensed) to the upper plate 19 through the discharge port 67. An open / close shutter 68 is attached to the discharge port 67, and the shutter 68 is configured to close the discharge port 67 by an urging force of a spring or the like when the front frame set 14 is opened (the state in FIG. 3). ing. Further, when the front frame set 14 is closed, the shutter 68 is configured to be pushed open by a ball passage rod 69 (see FIG. 2) provided on the back surface of the front frame set 14. Accordingly, in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 19 is directly provided to the front frame set 14, the game balls in the payout passage and the like are spilled off when the front frame set 14 is opened. Inconvenience can be prevented.

  As shown in FIG. 3, the resin base 20 is provided with a substantially rectangular small window 71 at the lower right portion of the window hole 21. Therefore, a seal or the like stretched in the adhering space K1 at the lower right corner of the game board 30 can be viewed through the small window 71. Further, a sticker or the like can be attached from the small window 71.

  Support metal fittings 81 and 82 are attached to the left end portion of the inner frame 12 in FIG. 3 as a support mechanism for the front frame set 14. The upper support fitting 81 is provided with a support hole 83 having a notch on the front side of the figure, and the lower support fitting 82 is provided with a protruding shaft 84 protruding in the vertical direction. Further, support metal fittings 151 and 152 are attached to the right end portion of the front frame set 14 in FIG. 5 (left end portion when viewed from the front of the pachinko machine 10) as a support mechanism for the inner frame 12. Accordingly, the front frame set 14 can be opened and closed with respect to the inner frame 12 by assembling the support brackets 151 and 152 on the front frame set 14 side to the support brackets 81 and 82 (see FIG. 3) on the inner frame 12 side. Can be installed. Further, since the support hole 83 of the support fitting 81 has a notch and the lower end portion of the support fitting 151 is formed thin as shown in FIG. 5, the support fitting 151 does not have to be completely removed from the support hole 83. The front frame set 14 can be easily detached from the inner frame 12 (the pachinko machine 10) by passing the thin part of the support fitting 151 through the notch of the support hole 83. The structure in which the lower plate unit 13 is supported by the inner frame 12 so as to be opened and closed may be the same as the structure in which the front frame set 14 is supported by the inner frame 12 so as to be opened and closed, or may be a different structure. . The support structure that supports the lower tray unit 13 and the like so as to be openable and closable is known, and various known structures can be used as the structure.

  Next, the front frame set 14 will be described with reference to FIGS. 1 and 5. FIG. 5 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 101 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 101 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. You may form the approximate center part of this window part 101 linearly. In the present embodiment, the distance between the upper end of the window portion 101 (the uppermost portion of the outer rail mounting portion 52 and the upper end of the game area) and the upper end of the front frame set 14 (the so-called upper and lower width of the upper frame portion) is 61 mm. It is significantly shorter than the prior art with an upper frame width of about 85 mm to 95 mm. As a result, the upper area of the game area can be easily secured, and the large variable display device unit 35 can be disposed relatively upward. The distance from the upper end of the front frame set 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

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

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light-emitting means play a role of enhancing the effect of the game during the game by changing or controlling the light-emitting mode by turning on or flashing according to the change in the gaming state at the time of big hit or predetermined reach. For example, at the periphery of the window portion 101, an annular illumination portion 102 containing a light emitting means such as an LED is provided symmetrically, and at the center of the annular illumination portion 102 and at the top of the pachinko machine 10, Similarly, a central illumination unit 103 having a built-in light emitting means such as an LED is provided. In the pachinko machine 10, the central illumination unit 103 functions as a jackpot lamp, and lights and blinks at the time of jackpot to notify that the jackpot is being hit. Further, the upper plate 19 is also provided around the upper plate 19 with an upper plate illumination unit 104 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 provided a prize ball lamp 105 that is lit during the payout of a prize ball and an error display lamp 106 that is lit when a predetermined error occurs.

  Further, a small window 107 to which a transparent resin is attached is provided so as to be able to visually recognize a part of the inner frame 12 surface, the game board 30 surface, and the like so as to be adjacent to the lower end portion of the annular illumination portion 102. The annular illumination part 102 is formed in a convex shape toward the front, whereas the small window 107 is formed flat. As described above, since the sticking space K1 and K2 for sticking seals and plates such as certificate stamps are provided on the back of the small window 107, the contents of the stickers and the like attached thereto are displayed on the scanner. It is flattened so that it can be optically read by a reading device. In addition, by forming the small window 107 flat, a rental ball rail of a ball lending machine (not shown) disposed between the two pachinko machines 10 does not protrude from the pachinko machine 10 to the player side. Thus, a ball lending machine can be provided.

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

  As shown in FIG. 5, various reinforcing members made of metal are provided on the back side of the front frame set 14 so as to surround the window portion 101. Specifically, reinforcing plates 131, 132, 133, and 134 are attached to the back side of the front frame set 14 and on the upper, lower, left, and right sides of the window portion 101, respectively. 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 FIG. . The resin parts 135 prevent the metal reinforcing plates 131 to 134 from being loop-connected by the front frame set 14. When the metal reinforcing plates 131 to 134 are connected in a loop, the electromagnetic noise associated with the launching operation of the game ball loops around the front frame set 14 disposed on the front surface of the game board 30, and the game board 30 has an adverse effect on the pachinko machine 10 and causes a malfunction, but in the pachinko machine 10 according to the present embodiment, the resin parts 135 avoid the annular connection of the metal reinforcing plates 131 to 134. The adverse effect of such noise can be suppressed. In addition, the strength reduction by using the resin part 135 for a part of the metal reinforcing plates 131 to 134 is compensated by providing the resin part 135 with a rib or increasing the thickness of the resin part 135. .

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

  The lower reinforcing plate 134 is provided with a resin rail side wall member 136 at a position facing the firing rail 61 (see FIG. 3). The rail side wall member 136 functions as a side wall of the launch rail 61 when the front frame set 14 is closed, and functions so that game balls do not spill from the launch rail 61.

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

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

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

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

  Further, the rail cover 140 is formed with a ridge 142 extending in an arc shape along the inner edge thereof and projecting toward the front side of FIG. When the front frame set 14 is closed, the protrusion 142 is configured to overlap the inner rail portion 51 substantially integrally with the protrusion 142 entering the guide rail. Therefore, for example, even if a wire or the like is intruded through a gap between the front frame set 14 and the inner frame 12 to perform an illegal act, it is very difficult to infiltrate the wire or the like into the game area inside the guide rail. Become. As a result, fraudulent acts performed using a wire or the like can be prevented. Note that the protrusion 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 or the like to enter in a wider range, and it is possible to more surely prevent an illegal act performed using the wire or the like.

  Next, the configuration of the back surface of the pachinko machine 10 will be described in detail with reference to FIGS. FIG. 6 is a rear view of the pachinko machine 10, and FIG. 7 is an exploded perspective view showing the rear structure of the pachinko machine 10 exploded for each main part.

In this embodiment, various control boards are divided into two mounting bases to form two control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. ing. In this case, the main board and the sound lamp control board are mounted on one mounting base to form a unit, and the dispensing control board, launch control board, and power supply board are mounted on the other mounting base to form a unit. Here, for convenience, the former unit is referred to as “first control board unit 201”, and the latter unit is referred to as “second control board unit 202”. In addition, since the dispensing mechanism and the protective cover are integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203”. The detailed configuration of each unit 201 to 203 will be described later.

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

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

  The first control board unit 201 is provided with a support shaft part M1 at the left end when viewed from the back of the pachinko machine 10, and the first control board unit 201 can be opened and closed around the axis A of the support shaft part M1.

The back pack unit 203 is fixedly held to the main body of the pachinko machine 10 by these fastening portions M7 and the locking portions M8, M9.

  The development 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 are It is configured to open on the right.

  On the other hand, FIG. 9 is a rear view showing a state in which the game board 30 is assembled to the inner frame 12. FIG. 10 is a perspective view of the inner frame 12 as viewed from the rear, and FIG. 11 is a perspective view of the game board 30 as viewed from the rear. Here, the back side structure of the inner frame 12 and the game board 30 will be described with reference to FIGS.

  The game board 30 is installed in a square frame-shaped installation area surrounded by the resin base 20 and does not fall off by a plurality of (four in this embodiment) locking fixtures 211 and 212 provided on the inner frame 12. So that it is fixed. The locking fixtures 211 and 212 can be manually rotated, and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 9 shows a state where the locking fixtures 211 and 212 are in the locked position. The locking fixtures 211 at the three left and right sides of the game board 30 are configured by L-shaped metal fittings formed by bending metal pieces, and are configured so as not to protrude outward from the inner frame 12 in a state where the game board 30 is fixed. ing. The locking fixture 212 at one lower portion of the game board 30 is formed of a resin I-type fastener.

  A variable display device unit 35 is disposed in the center of the game board 30. In the variable display device unit 35, a frame cover 213 made of resin (for example, made of ABS) that covers the center frame 47 (see FIG. 4) from behind is provided to protrude rearward, and at the rear end of the frame cover 213, A large-sized symbol display device 42 as a liquid crystal display device and a display control device 45 are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 213, an LED control board for driving LEDs and the like built in the center frame 47 are disposed.

  A back frame set 215 is attached to the back surface of the game board 30 so as to surround the variable display device unit 35. The back frame set 215 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 30, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 215, it corresponds to the opening portion of the game board 30 of the general prize opening 31, the variable prize winning device 32, and the big prize opening 33 (see FIG. 4 respectively) described above, and at one place on the downstream side. A collecting passage 216 is formed. Also, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is attached below the game board 30, and the discharge passage board 217 is used for guiding the discharge ball to the outside of the pachinko machine 10. A discharge passage 218 is formed. Therefore, as illustrated in phantom lines in FIG. 9, all the game balls won in the general winning opening 31 etc. gather through the collection passage 216 of the back frame set 215, and further, the discharge passage 218 of the discharge passage board 217 is formed. Through the pachinko machine 10. Similarly, the out port 36 (see FIG. 3) communicates with the discharge passage 218, and the game balls that have not won any prize opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

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

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

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

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

  Although not shown in the drawings, the variable winning device 32 is provided with a large winning opening solenoid for opening the large winning opening and a winning ball sorting plate solenoid for guiding the winning ball to a specific area. Is provided with an operating port solenoid for opening the electric accessory. In FIG. 9, a launch unit 228 including a hitting ball basket or the like is disposed on the lower left portion of the back surface of the pachinko machine 10, and a launch solenoid 229 is connected to the launch unit 228.

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

  The back frame set 215 is provided with an attachment mechanism for attaching the first control board unit 201. Specifically, as shown in FIG. 11, as the attachment mechanism, a support fitting 231 extending in the vertical direction is provided at the lower left corner when viewed from the back of the game board 30, and the support fitting 231 is on the same axis.

In addition, as an attachment mechanism for the back pack unit 203, the inner frame 12 is provided with a pair of upper and lower fastening holes (ny latch holes) 240 at the left end of the game board installation area. However, the support bracket for the second control board unit 202 and the support bracket for the back pack unit 203 can be provided as separate members. In addition, as a mounting mechanism for the back pack unit 203, three rotary fixtures 241, 242, and 243 are provided on the inner frame 12, and between these fixtures 241, 242, and 243 and the game board 30 are provided. The back pack unit 203 is sandwiched and supported.

  In addition, in the rear configuration of the inner frame 12, a game ball for distributing a game ball paid out from a payout mechanism, which will be described later, to either the upper plate 19, the lower plate 15, or the discharge passage 218, at the lower right portion of the game board 30. A distribution unit 245 is provided. That is, the opening 245a of the game ball distribution unit 245 shown in FIG. 10 is configured to communicate with the upper plate 19, the opening 245b communicates with the lower plate 15, and the opening 245c communicates with the discharge passage 218. Further, a resin speaker box 246 surrounding the back of the speaker hole 24 formed in the lower plate 15 is attached to the lower end portion of the inner frame 12, and the speaker is installed in the speaker box 246. The speaker box 246 improves the sound quality in the low sound range.

  Next, a locking device for locking the inner frame 12 to the outer frame 11 and locking the front frame set 14 and the lower tray unit 13 to the inner frame 12 will be described with reference to FIGS. The locking device includes a locking unit 410 (see FIG. 1) that is vertically disposed on the back surface of the inner frame 12 and on the right side of the pachinko machine 10 when viewed from the front, and a hook member 411 that is slidably provided on the locking unit 410. To 413, and the receiving frame 401-403 (refer FIG. 2) which maintains the state which closed the inner frame 12, the front frame set 14, etc. is comprised.

  FIG. 13A is a diagram showing the locking unit 410 viewed from the right side when the pachinko machine 10 is attached, and FIG. 13B shows the locking unit 410 when viewed from the rear when the pachinko machine 10 is installed. It is a figure. In order to avoid complication of the drawings, some of the coil springs 421 to 424 are simplified in the drawings after FIG.

  When the inner frame 12 is closed, the locking unit 410 has the inner frame collar member 411 that closes the inner frame 12 with respect to the outer frame 11 and restricts movement in the opening direction, and the front frame set 14 is closed. And the lower frame unit 412 for closing the lower plate unit 13 and closing the lower plate unit 13 to restrict the movement of the lower plate unit 13 in the opening direction. The hook member 413, the coil springs 421 to 423 for biasing the hook members 411 to 413 to one side, and the hook members 411 to 413 and the coil springs 421 to 423 formed to extend in the vertical direction when attached to the pachinko machine 10. It includes a collar base 414 that is integrally supported, and a cylinder lock 450 that operates in response to an operation with a dedicated key K. In addition, two inner frame collar members 411 and two front frame collar members 412 are provided, and two coil springs 421 and 422 for biasing them to one side are also provided. Supported in two places.

  The base 414 is formed by bending a long metal plate substantially at a right angle into a L-shaped cross section, and a main plate 414a formed substantially parallel to the surface of the game board 30 and a substantially orthogonal to the main plate 414a. Side plate 414b. A plurality of mounting holes are formed in the main plate 414a, and screws are inserted into the mounting holes, and the locking unit 410 is attached to the back side of the inner frame 12. A cylinder lock 450 is screwed to the main plate 414a with two screws 455, and an operating member 415, two upper and lower inner frame collar members 411, and two upper and lower front frame collars are coupled to the side plate 414b. The member 412 and the lower plate bowl member 413 are supported to be slidable with respect to the bowl base 414 (inner frame 12). Note that the flange members 411 to 413 and the operating member 415 do not necessarily have to be slidably supported with respect to the flange base 414, and may be anything that supports to be slidable with respect to the flange base 414. For example, the rod base 414 may be configured so that the rod member or the actuating member supports the rod member or the actuating member so that the rod member oscillates or pivots, and swings or pivots with the sliding member. You may comprise so that a collar member or an action | operation member may slide with the some member linked with the member.

  The actuating member 415 is a long plate-like member extending along the longitudinal direction of the saddle base 414, and is supported on the side plate 414b by two guide pins 431 at two upper and lower portions thereof. The operation member 415 slides along the side plate 414b in conjunction with the operation of the cylinder lock 450 by the dedicated key K formed in a specific shape, and this operation will be described later.

  A hook member (an inner frame hook member) 411 that can be engaged with the upper receiving metal fitting 401 fixed to the outer frame 11 is provided at the upper end of the operating member 415 so as to protrude to the back side of the pachinko machine 10. The lower end portion of the operating member 30 is provided with a lower inner frame flange member 411 formed to protrude in the same shape as the upper side. These two inner frame hook members 411 are involved in locking or unlocking the inner frame 12, and are supported by the guide pins 431 on the side plate 414b of the rod base 414 and slide along the longitudinal direction of the side plate 414b. It is provided as possible.

  The side plate 414b of the heel base 414 has an inner frame heel member at the front end in the width direction at the portion where the inner frame ridge member 411 is disposed (the end on the front side in the direction perpendicular to the sheet of FIG. 13B). The rib 414c is formed by being bent toward the 411 side. The rib 414c restricts the inner frame collar member 411 from moving to the back side of the pachinko machine 10, and the inner frame collar member 411 moves up and down while being sandwiched between the rib 414c and the main plate 414a. Further, as shown in FIG. 13B, the ribs 414c are formed intermittently except for the vicinity of the inner frame collar member 411 and the cylinder lock 450, and the actuating member 415 is formed on the pachinko machine 10 by the rib 414c. The back side is covered.

  Here, with reference to FIGS. 14 and 15, the structure of the locking unit 410 will be described in detail, focusing on the operating member 415, the lower inner frame collar member 411, and the front frame collar member 412. 14 and 15 are enlarged views of the vicinity of the cylinder lock 450 of the locking unit 410 in FIGS. 13 (a) and 13 (b). A guide pin 431 protrudes from one side surface of the inner frame collar member 411, and the guide pin 431 is engaged in a guide groove 414b1 that is elongated along the longitudinal direction of the side plate 414b. The guide pin 431 includes a shaft portion formed narrower than the width of the guide groove 414b1 (the width in the left-right direction in FIG. 14) and a head having a diameter larger than the width of the guide groove 414b1, and the diameter of the guide pin 431 is increased. The head slides while contacting the outer side surface of the side plate 414b. Therefore, the inner frame collar member 411 can slide within a range in which the guide pin 431 can move along the longitudinal direction of the guide groove 414b1 (vertical direction in FIG. 14) while maintaining a parallel state with respect to the side plate 414b. It has become.

  The inner frame collar member 411 has a coil spring 421 supported at one end by a hook portion 411a projecting from one side thereof and supported at the other end by a hook portion 414a1 projecting from a main plate 414a of the collar base 414. It is erected. The coil spring 421 is stretched so as to constantly urge the inner frame collar member 411 toward the lower side of the inner frame 12 (the lower side in FIG. 14), and the guide pin 431 has a lower end of the guide groove 414b1. The movement of the inner frame collar member 411 is restricted by contacting the portion (the lower end portion of the guide groove 414b1 in FIG. 14). In a state in which this movement is restricted, the inner frame collar member 411 engages with the receiving metal fitting 401 attached to the outer frame 11 to close the outer frame 11 (solid line position in FIG. 14). Positioned.

  Further, the inner frame collar member 411 is normally biased downward (lower side in FIG. 13) by a coil spring 421 provided in each, and the guide pin 431 comes into contact with the lower end portion of the guide groove 414b1. Arranged in the closed position. When a force is applied to the inner frame collar member 411 itself and pulled upward, the inner frame collar member 411 moves upward alone while the coil spring 421 is stretched, and the release position where the engagement with the metal fitting 401 is released. It is possible to move to (two-dot chain line position in FIG. 14). At this time, the guide pin 431 fixed to the inner frame collar member 411 relatively moves in the escape groove 415a of the operating member 415, and the operating member 415 remains in the closed position. For this reason, even if one of the upper and lower inner frame collar members 411 is pushed up with a special tool to perform an illegal act, the other inner frame collar member 411 is kept in the closed position, and the inner frame 12 is opened. I can't. In order to open the inner frame 12 illegally, it is necessary to push up both the upper and lower inner frame collar members 411 to the open position at the same time, making it difficult to execute the illegal acts and improving crime prevention. Yes.

  As shown in FIG. 15, an operation member 415 is disposed between the side plate 414 b and the inner frame collar member 411. In the operating member 415, a relief groove 415 a that is formed wider than the shaft portion of the guide pin 431 is formed in a vertically long shape along the longitudinal direction of the flange base 414. When the inner frame collar member 411 is in the closed position, the guide pin 431 is disposed in contact with the lower end portion (lower end portion in FIG. 15) of the escape groove 31.

  When the actuating member 415 moves downward from the closed position shown in FIG. 15 (see FIG. 18B), the front frame collar member 412 is actuated by the actuating member 415 from the closed position to the open position. At this time, the guide pin 431 is maintained in contact with and supported by the lower end portion of the guide groove 414b1 of the base 414, and the actuating member 415 is lowered along the direction in which the escape groove 415a is formed with respect to the guide pin 431. Move. For this reason, even if the guide pin 431 moves along the escape groove 414b1 and the operating member 415 moves downward from the closed position, the inner frame collar member 411 does not move downward, and the inner frame collar member 411 and the receiving metal 401 The engagement state is not released.

  On the other hand, when the operating member 415 moves upward from the closed position shown in FIG. 15 (see FIG. 18A), the inner frame collar member 411 is operated by the operating member 415 from the closed position to the open position. That is, the inner frame flange member 411 is moved upward (moved upward in FIG. 15) while the lower end portion of the escape groove 415a presses the guide pin 431 upward. When the actuating member 415 is pulled upward by a force that resists the elastic force of the coil spring 421, the inner frame collar member 411 is lifted upward together with the guide pin 431.

  The upper inner frame collar member 411 is attached to the side plate 414b with the same structure as the lower inner frame collar member 411. For this reason, when the operating member 415 moves downward from the closed position in FIGS. 14 and 15, the upper and lower inner frame collar members 411 maintain a stationary state without engaging with the operating member 415. When the actuating member 415 moves upward, it moves together with the actuating member 30 and slides from the closed position to the open position (see FIG. 18A). Is disengaged. That is, the state of locking and unlocking of the inner frame 12 with respect to the outer frame 11 is switched by the position change of the inner frame collar member 411 accompanying the upward movement of the operating member 415. Note that the inner frame 12 of the pachinko machine 10 is not opened forward just by being unlocked, as in a general pachinko machine, but the operator who performed the unlocking operation intentionally on the near side. As long as the opening operation is not performed, the closed state is maintained.

  Here, the receiving metal fitting 401 that engages with the inner frame collar member 411 will be described with reference to FIG. FIG. 16 is a perspective view showing the receiving metal fitting 401 fixed to the outer frame 11 when viewed in the direction of the arrow Vb in FIG. The metal fitting 401 is screwed to the inner surface side of the outer frame 11 formed in a frame shape with screws, and the inner frame collar member 411 is fixed at two upper and lower positions located at the time of closing. The metal fitting 401 is formed by bending a metal, and the tip of the inner frame hook member 401 is hooked on a portion protruding toward the inner surface side (lower right side in FIG. 16) of the outer frame 11. 12 is closed. Here, a protruding portion 401a that is bent so as to protrude in the direction in which the distal end portion of the inner frame collar member 411 enters (the lower left side in FIG. 16) is formed at the distal end portion on the inner surface side. The protruding portion 401a is formed long so as to overlap the tip portion protruding downward of the inner frame collar member 411 in a side view when the inner frame 12 is closed. It is possible to prevent the inner frame collar member 411 from being accidentally detached from the receiving metal fitting 401 due to rattling or the like. In the pachinko machine 10, the inner frame ridge member 411, the front frame ridge member 412, and the lower dish ridge member 413 are all slid along the vertical direction of the pachinko machine 10. The direction does not need to be configured to move in any direction, and may be any direction as long as the direction intersects the opening / closing direction of the inner frame 12 and the front frame set 14 such as the left-right direction and the diagonal direction of the pachinko machine 10.

  Returning to FIG. As shown in FIG. 13 (b), front frame flange members 412 for closing the front frame set 14 with respect to the inner frame 12 are provided at two locations above and below the operating member 415. The front frame collar member 412 is formed in a vertically long shape facing the main plate 414a of the collar base 414, and an engagement hole 412a formed in a substantially rectangular shape in the front view is provided at the upper center of the front frame. A first guide groove 412b formed in a vertically long shape is provided below the hole 412a. Further, the urging member 412 for the front frame is given an urging force to be pulled upward with respect to the heel base 414 by the coil spring 422 that is extended and installed. In the pachinko machine 10, the coil spring 422 is stretched to apply the urging force to the flange members 411 to 413. However, it is not always necessary to apply the urging force by the coil spring 422, and other force such as a torsion spring or a leaf spring is used. Even if it is an elastic body, what is necessary is just to provide the urging | biasing force which urges | biases the collar members 411-413 to the one side with respect to the collar base 414. FIG.

  A guide pin 432a fixed to the main plate 414a is inserted through the first guide groove 412b. The front frame flange member 412 is slidable downward relative to the flange base 414 by the amount that the first guide groove 412b is formed above the guide pin 432a.

  Further, the front frame flange member 412 is formed by bending a flat plate so that both edges along the left-right direction of the pachinko machine 10 protrude rearward and have a U-shaped cross section. A second guide groove 412c formed in a vertically long oval shape is provided on a plane parallel to the side plate 414b of the saddle base 414 in order to engage the guide pin 432b installed on the base plate 414. By adopting a U-shaped cross section, it is easier to ensure high strength while reducing the space on the side of the locking unit 410 in the width direction than in the case of a flat plate shape. A guide pin 432b fixed to the operating member 415 is inserted into the second guide groove 412c, and the second guide groove 412c is formed above the guide pin 432b. The member 412 is slidable downward.

  The rib 414c formed at the tip of the side plate 414b of the heel base 414 is formed by being bent at a position covering the front frame heel member 412, and a part of the front frame ridge member 412 is covered by the rib 414c. . The rib 414c restricts the front frame collar member 412 from moving to the back side of the pachinko machine 10, and the front frame collar member 412 moves up and down while being sandwiched between the rib 414c and the main plate 414a.

  The engagement hole 412a of the front frame flange member 412 is a part that engages with a receiving metal fitting 402 (see FIG. 10) provided in the front frame set 14 to restrict the opening of the front frame set 14, and is an engagement hole. The front metal frame set 14 is closed by catching the receiving metal fitting 402 whose tip portion protrudes downward on the lower edge of 412a. Here, the front frame flange member 412 may be formed to protrude to the front surface side of the pachinko machine 10 and the tip portion protrudes upward or downward. However, the front frame flange member 412 has an engagement hole 412a. It is preferable that the hook member 412 is formed so as not to protrude to the front side, and the receiving metal fitting 402 protruding to the front frame set 14 side is formed. In the pachinko machine 10, game balls may be clogged or caught on the game board 30 on which nails, windmills, etc. are arranged. In order to remove this, the front frame set 14 may be opened to perform work. Many. At this time, if there is a metal member protruding forward from the inner frame 12 side, it is dangerous because it is caught by the operator's hand or body protruding part. By projecting the receiving metal fitting 402 on the front frame set 14 side, even if a hand is caught on the projecting portion, the amount of opening of the front frame set 14 is increased and there is less danger, and the safety of work can be improved.

  The upper and lower two front frame collar members 412 slide simultaneously when the operation member 415 operates in a predetermined direction, like the inner frame collar member 411 described above. That is, when the operating member 415 moves upward while the front frame collar member 412 is stationary, the guide pin 432b provided on the operating member 415 moves along the guide groove 412c shown in FIG. The scissor member 412 continues to be placed in the closed position without engaging the actuating member 415. On the other hand, when the actuating member 415 moves downward, the guide pin 432b of the actuating member 415 pushes down the front frame collar member 412 while abutting against the lower end of the guide groove 412c. When the operating member 415 moves downward, the front frame collar member 412 also moves downward. The front frame flange member 412 has a lower edge of the engagement hole 412a from the closed position where the lower edge of the engagement hole 412a is engaged with the reception metal fitting 402, and the engagement hole 412a and the reception metal fitting 402 are lowered. It moves to the open position where the engaged state is released, and the front frame set 14 becomes openable. That is, locking or unlocking of the front frame set 14 is switched according to a change in the position of the front frame flange member 412 accompanying the downward movement of the operation member 415.

  In addition, the front frame flange member 412 is normally biased upward (upper side in FIG. 13) by a coil spring 422 provided on each of the front frame flange members 412, and the lower end portion of the guide groove 412 b comes into contact with the guide pin 432 a and is stationary. It has become. When a force is applied to the front frame collar member 412 itself to pull it down, the front frame collar member 412 moves downward alone while the coil spring 422 is stretched. For this reason, as with the inner frame collar member 411, even if the front frame collar member 412 is pushed down with a special tool in order to perform an illegal act, the front frame set 14 cannot be opened, and the illegal act The security is improved by making it difficult to execute.

  The actuating member 415 transmits the operating force applied to the dedicated key K to the cylinder lock 450 to the upper and lower two of the inner frame collar member 411 or the front frame collar member 412 to transmit the inner frame 12 and the front frame set 14. It is a member for unlocking. The operating member 415 is maintained in the closed position shown in FIGS. 13 to 15 in a state where the operation with the dedicated key K is not performed on the cylinder lock 450. That is, the coil spring 421 installed on the inner frame collar member 411 urges the guide pin 431 fixed to the inner frame collar member 411 downward, so that the operating member 415 moves upward from the closed position. Is regulated. On the other hand, when the coil spring 422 installed on the front frame collar member 412 biases the guide pin 432b fixed to the operating member 432b upward, the operating member 415 moves downward from the closed position. Is regulated. Thereby, if the operation by the exclusive key K is not performed, the operation member 415 is maintained in the closed position.

  Further, the inner frame collar member 411 (guide pin 431) is arranged to oppose the upper side of the operating member 415 so as to be interlocked with the upward movement of the operating member 415, while on the front surface so as to be interlocked with the downward movement of the operating member 415. The frame collar member 412 is disposed to face the lower side of a part of the operating member 415 (guide pin 432b fixed to the operating member 415). For this reason, the inner frame collar member 411 and the front frame collar member 412 can be switched and operated in accordance with the operating direction of the single actuation member 415, and the structure of the actuation member 415 is simplified. The contents of the operation member 415 interlocking with the operation of the dedicated key K will be described later.

  As shown in FIGS. 13 and 14, the cylinder lock 450 is provided below the center of the main plate 414 a of the saddle base 414. A pair of mounting holes for the cylinder lock 450 are provided in the main plate 414a of the rod base 414, and both upper and lower ends of the cylinder lock 450 are screwed into the mounting holes with screws 455. The cylinder lock 450 is attached by being inserted into an opening hole 414e formed in the main plate 414a, and the saddle base 414 is formed in a shape that surrounds the left and right sides of the cylinder lock 450 by the side plate 414b and the rib 414d. ing.

  FIG. 17 is a cross-sectional view of the locking unit 410 taken along the line Sa-Sa in FIG. The base 414 is provided with an opening hole 414e through which the cylinder lock 450 is inserted, and both end portions thereof are bent into a U-shaped cross section so as to sandwich the end portion on the back side of the cylinder lock 450. Yes. A load is frequently applied to the cylinder lock 450 by locking and unlocking operations, and from the viewpoint of crime prevention, it is preferable that the cylinder lock 450 and its peripheral part have high strength and rigidity to be strong. If an opening hole is formed in the heel base 414 in order to insert the lock 450, the strength and rigidity of the peripheral portion thereof are lowered. Although the strength reduction can be compensated by forming the base 414 widely, the width of the locking unit 410 in the left-right direction in the front view of the pachinko machine 10 is increased correspondingly, and the game board 30 surface and the back surface of the pachinko machine 10 are increased accordingly. The layout space for parts is reduced, and the degree of freedom in design layout is reduced. Since the saddle base 414 of the pachinko machine 10 is formed to be bent in a U-shaped cross section so as to sandwich the end of the cylinder lock 450, the width of the locking unit 410 in the left-right direction (vertical direction in FIG. 16) is increased. While reducing the strength, the strength around the opening hole 414e can be secured, the locking unit 410 can be formed in a compact manner, and the degree of freedom of other component layout can be increased.

  Further, since the rib base 414 is bent and formed in a U-shaped cross section so as to sandwich the end portion of the cylinder lock 450, and a rib 414d is formed, the wire is directed toward the back side of the cylinder lock 450 (the right side in FIG. 17). Even if a tool such as the above is inserted, the progress is prevented by the rib 414d. For this reason, it is possible to increase the security against fraud by making it difficult to illegally operate the cam 452 on the back side of the cylinder lock 450 without using the dedicated key K.

  The cylinder lock 450 has a built-in lock shaft that is uniquely linked to the rotation operation of the dedicated key K, and a plurality of protrusions projecting to the upper right side and the lower right side in the rear view of the pachinko machine 10 on the back side of the cylinder lock 450. The cam 452 having the arm portions 452a and 452b is screwed with screws. In addition, since the internal structure of the cylinder lock 450 is general, the description thereof is omitted.

  As shown in FIG. 15, the operating member 415 protrudes to the upper right side of the cam 452 and the first engagement groove 415 b that can be engaged with the first arm portion 452 a that protrudes to the lower right side of the cam 452. A second engagement groove 415c that can be engaged with the second arm portion 452b is formed. When the dedicated key K is rotated in a state where the dedicated key K is inserted into the cylinder lock 450, the cam 452 moves in the counterclockwise direction (see FIG. 18A) in FIG. 15 or the clockwise direction (see FIG. 18). (See (b)). When the cam 452 rotates in either direction, the first arm portion 452a or the second arm portion 452b enters the corresponding first engagement groove 415b or the second engagement groove 415c and enters the grooves 415b and 415c, respectively. When the operating member 415 is pushed upward or downward by engaging with one end of the operating member 415, the operating member 415 moves (downward or upward). As the actuating member 415 moves, the inner frame collar member 411 or the front frame collar member 412 is moved from the closed position to the open position, and the closed inner frame 12 or front frame set 14 can be opened. Locking and unlocking can be performed by operating the dedicated key K.

  Here, the actuating member 415 is formed of a single member in which a guide pin 432b is fixed to a metal plate, and a relief groove 415a that abuts against the inner frame collar member 411 and a guide pin that abuts against the front frame collar member 412. 432b and engagement grooves 415b and 415c that contact the cam 452 of the cylinder lock 450 are formed side by side along the longitudinal direction of the operating member 415. For this reason, the number of parts of the locking unit 410 can be reduced as compared with the case where the actuating member for actuating the inner frame collar member 411 and the actuating member for actuating the front frame collar member 412 are provided separately. The manufacturing cost can be reduced, and the locking unit 410 can be formed in a light weight. Further, since the portions that contact the inner frame collar member 411, the front frame collar member 412 and the cam 452 of the cylinder lock 450 are formed side by side along the longitudinal direction of the actuation member 415, the actuation member is formed. The width of 415 can be formed linearly with a small width, and the locking member 410 can be made compact by forming the operating member 415 compactly.

  Next, the unlocking operation of the locking unit 410 using the dedicated key K will be described with reference to FIGS. 15 and 18. 18A is a diagram showing the vicinity of the cylinder lock 450 of the locking unit 410 in a state where the inner frame 12 is unlocked, and FIG. 18B is a diagram showing the front frame set 14 unlocked. It is the figure which looked at the cylinder lock 450 vicinity of the locking unit 410 in a state by the back view.

  In the locked state where the inner frame 12 and the front frame set 14 are closed and the dedicated key K is not inserted into the keyhole of the cylinder lock 450 and operated, as shown in FIG. 415 is disposed at the neutral closed position without engaging with the arm portions 452a and 452b of the cam 452. In a state where the actuating member 415 is disposed at the neutral closed position, the inner frame collar member 411 and the front frame collar member 412 are disposed at the closed positions where the inner frame collar members 411 and 402 are engaged with the corresponding metal fittings 401 and 402, respectively. The locked state in which the frame 12 and the front frame set 14 cannot be opened is maintained.

  When the inner frame 12 is unlocked from the locked state (the state shown in FIG. 15), the dedicated key K is inserted into the keyhole of the cylinder lock 450, and the dedicated key K is viewed from the front of the pachinko machine 10 (see FIG. 1). To rotate clockwise (clockwise in FIG. 1). In the state shown in FIG. 15 when the pachinko machine 10 is viewed from the back, the cam 452 rotates counterclockwise (counterclockwise in FIG. 15) in conjunction with the rotation operation of the dedicated key K. By this rotation, the first arm portion 452a of the cam 452 enters the first engagement groove 415b of the operating member 415 and comes into contact with the upper end portion thereof, and then the cam 452 rotates counterclockwise as the cam 452 rotates counterclockwise. The first arm portion 452a pushes up the operating member 415 to move the operating member 415 upward. When the actuating member 415 moves upward, the lower end portion of the relief groove 415a formed in the actuating member 415 engages with the guide pin 431 projecting from the inner frame flange member 411, and the guide pin 431 is moved upward. The frame collar member 411 moves up. The inner frame collar member 411 is moved upward and downward at two locations, and when the operating member 415 is moved upward, the two inner frame collar members 411 provided at the upper and lower locations are moved upward.

  Further, when the dedicated key K is rotated clockwise in the front view of the pachinko machine 10 and the amount of rotation reaches about 60 degrees, the cam 452 is rotated about 60 degrees counterclockwise in FIG. 15 from the locked state. The state shown in FIG. 18A (the unlocked state of the inner frame 12) is obtained. In this state, the inner frame flange member 411 is moved up by a certain distance together with the operating member 415 by the rotation of the cam 452, and the inner frame flange member 411 and the corresponding metal fitting 401 (see FIG. 2). The engagement is released. By releasing the engagement between the inner frame collar member 411 and the metal fitting 401, the inner frame 12 is in an unlocked state in which the movement restriction in the opening direction is released, and the inner frame 12 can be opened to the front side.

  On the other hand, when the front frame set 14 is unlocked from the locked state (the state shown in FIG. 15), the dedicated key K is inserted into the key hole of the cylinder lock 450, and the dedicated key K is inserted into the front of the pachinko machine 10 (see FIG. 1). ) To rotate counterclockwise (counterclockwise in FIG. 1). In the state shown in FIG. 15 when the pachinko machine 10 is viewed from the back, the cam 452 rotates clockwise (clockwise in FIG. 15) in conjunction with the rotation operation of the dedicated key K. By this rotation, the second arm portion 452b of the cam 452 enters the second engagement groove 415c of the operating member 415 and contacts the lower end portion of the second engagement groove 415c, and then the cam 452 rotates clockwise. Accordingly, the second arm portion 452a of the cam 452 pushes down the operating member 415 to move the operating member 415 downward.

  Further, when the dedicated key K is rotated counterclockwise in the front view of the pachinko machine 10 and the amount of rotation reaches about 60 degrees, the cam 452 is rotated about 60 degrees clockwise from the locked state in FIG. The state shown in FIG. 18B (the unlocked state of the front frame set 14) is obtained. In this state, the rotation of the cam 452 causes the front frame flange member 412 to move downward by a predetermined distance together with the operating member 415, and the front frame flange member 412 and the corresponding receiving metal piece 402 (see FIG. 9). The engagement is released. By releasing the engagement between the front frame collar member 412 and the receiving metal fitting 402, the front frame set 14 is unlocked in which the movement restriction in the opening direction is released, and the front frame set 14 can be opened to the front side. it can.

  Next, a stopper mechanism for restricting the opening of the inner frame 12 will be described with reference mainly to FIGS. 13 and 19. This stopper mechanism is a mechanism provided in order to improve the security against the opening of the inner frame 12.

  The stopper mechanism is composed of a stopper member 460 for restricting the upward movement of the operating member 415 and a coil spring 461 as an urging means for urging the stopper member 460 to one side. As shown in FIG. 13, the coil spring 461 is provided at the upper end portion of the saddle base 414.

  FIG. 19 is a view showing a state where the stopper mechanism of the locking unit 410 is operated. In FIG. 19, the coil spring 461 is omitted for easy understanding of the drawing. 19 (a) and 19 (b) show a state in which the upward movement of the operating member 415 is restricted by the stopper mechanism, and FIGS. 19 (c) and 19 (d) show the state above the operating member 415 by the stopper mechanism. It shows a state where the restriction of movement is released. 19 (a) and 19 (c) schematically show a cross section of the locking unit 410 at a position where the stopper member 460 is disposed, and in FIGS. 19 (b) and 19 (d), the locking unit is shown. 410 is a side view.

  As shown in FIG. 19B, the upper end portion of the actuating member 415 is lower on the front side (left side in FIG. 19B) of the pachinko machine 10 in the side view and higher on the rear side of the pachinko machine 10. It is formed in a shape protruding. The front-side upper end 415g that protrudes low is a part that abuts against the middle plate 460a of the stopper member 460 when the upward movement of the operating member 415 is restricted. Further, a groove 415h formed on the back side of the pachinko machine 10 from the front side upper end 415g is a portion into which the intermediate plate 460a enters when the upward movement of the operating member 415 is allowed.

  The stopper member 460 is a member formed by bending a metal plate, and has a front plate 460b extending from the heel base 414 to the front side of the pachinko machine 10 (the left side in FIG. 19B) when viewed from above, and one end Is connected to the front plate 460b and extends from one end of the front plate 460b toward the side plate 414b of the flange base 414, and the rear plate extends rearward from the other end of the intermediate plate 460a along the side plate 414b of the flange base 414. 460c and a spring mounting portion 460d formed on the back side of the plate 460c thereafter are provided.

  The stopper member 460 is arranged so that the middle plate 460a intersects the upper end 415g of the front side of the operating member 415, and the front side of the pachinko machine 10, that is, the coil spring 461 installed on the spring mounting portion 460d. The operation member 415 is maintained at a position intersecting the front side upper end 415g. In this state, the upward movement of the operating member 415 is restricted, and the inner frame collar member 411 interlocked with the upward movement of the operating member 415 cannot move from the closed position to the open position. For this reason, even if the operator inserts the dedicated key K into the keyhole and attempts to rotate the pachinko machine 10 clockwise as viewed from the front, the operating member 415 and the stopper member 460 come into contact with each other to prevent the rotation.

  When the stopper member 460 moves to the back side of the pachinko machine 10 and the middle plate 460a is disposed at a position overlapping the groove 415h of the operating member 415 when viewed from above (see FIG. 19C), the front side of the operating member 415 The upper end 415g and the middle plate 460a do not come into contact with each other, and the upward movement of the operating member 415 is allowed. The groove 415h of the operating member 415 is formed so deep that the inner frame collar member 411 interlocked with the upward movement of the operating member 415 can be moved from the closed position to the open position. The interlocking inner frame collar member 411 can move from the closed position to the open position. Therefore, with the stopper member 460 moved to the back side of the pachinko machine 10, the operator inserts the dedicated key K into the keyhole and rotates the pachinko machine 10 clockwise as viewed from the front, whereby the inner frame collar member 411 moves from the closed position to the open position, and the operator can open the inner frame 12.

  As shown in FIG. 2, the stopper member 460 is disposed so as to protrude to the front side of the inner frame 12, and is operated by inserting the dedicated key K into the key hole of the cylinder lock 450 while pushing the stopper member 460 to the rear side. Without this, the inner frame 12 cannot be unlocked. For this reason, the unlocking operation of the inner frame 12 is an operation performed using both hands, and the unlocking operation becomes more complicated than the unlocking of the inner frame 12 just by rotating the dedicated key K with one hand, and the unauthorized unlocking. Operation can be made difficult.

  Here, conventionally, since the inner frame 12 is unlocked and opened by rotating the dedicated key K, a criminal who has illegally obtained the dedicated key K inserts the dedicated key K into the key hole and inserts it into the inner frame. Even if 12 was opened illegally, it was inconspicuous. For this reason, there are cases in which the main control device 261 and the payout control device 311 arranged on the back side of the inner frame 12 are exchanged for illegal ones, or crimes for illegally operating to obtain unfair profits. .

  According to the pachinko machine 10, the stopper member 460 is provided on the upper side of the pachinko machine 10, and further requires the operation of both hands to rotate the dedicated key K while pressing the stopper member 460. Therefore, an unauthorized opening operation can be easily found by monitoring a camera, a store clerk, and the like, leading to a suppression of the willingness to commit a crime, and the security of the pachinko machine 10 can be improved.

  Also, the inner frame 12 hardly needs to be opened during the game. On the other hand, if the inner frame 12 is inadvertently opened, there is a possibility that the back side of the inner frame 12 can be seen, resulting in an illegal motive or an illegal act. It is not desirable to occur. According to the pachinko machine 10, the unlocking operation of the inner frame 12 cannot be performed unless the front frame set 14 is unlocked and opened and the stopper member 460 is operable. As compared with the pachinko machine 10 in which the inner frame 12 is unlocked and opened, the inner frame 12 is less likely to be opened and fraud is difficult.

  Since the stopper mechanism can improve crime prevention performance while reducing workability, the stopper member 460 and the coil spring 461 may be omitted to improve workability, and the pachinko machine may be configured without the stopper mechanism. .

  Next, the arrangement position of the locking unit 20 attached to the inner frame 12 will be described with reference to FIG. FIG. 20 is an enlarged view of the vicinity of the locking unit 20 when the pachinko machine 10 is viewed in cross section along the Sb-Sb line in FIG. 6.

  The operating member 415 for operating the inner frame collar member 411 and the front frame collar member 412 is folded back to the side where the central portion in the longitudinal direction intersects the sliding direction of the operating member 415. An operation portion 415d is provided so as to protrude so that a person can operate the operating member 415 with his bare hands. By applying a finger to the operation portion 415d and pushing it down, the operating member 415 is operated without operating the dedicated key K, and the front frame collar member 412 is simply moved from the closed position to the open position. It can be in an unlocked state.

  In addition, the inner frame 12 is in a closed state and comes into contact with (or in close proximity to) one end (front end) 11a of the outer frame 11, and faces the outer frame 11 from the facing portion 12b. Thus, a protrusion 12c formed with a step is provided, and the heel base 414 is attached to the protrusion 12c. Since the protruding portion 12c is formed to protrude to the outer frame 11 side from the facing portion 12b in a state in which the inner frame 12 is closed, the flange base 414 is located outside the position where the outer frame 11 and the facing portion 12b face each other. It is shifted and arranged on the frame 11 side. For this reason, even if a special tool is inserted into the locking unit 410 from the gap between the facing portion 12b of the inner frame 12 and the outer frame 11, a special tool is inserted into the locking unit 410 disposed at a position deviated from the gap. Makes it difficult for tools to reach, and can improve security against fraud.

  Further, the outer frame 11 is formed in a rectangular frame shape with an inner side (right side in FIG. 20) opened, and the operating member 415 is directed toward the front end side in the closing direction (arrow C direction in FIG. 20) of the inner frame 12. And a convex portion 11b protruding inward. This convex portion is formed so as to protrude in the direction of approaching the rib 414c of the heel base 414. The projection 11b covers the exposure member 415 on the back side of the pachinko machine 10 so that the exposed portion is reduced, and the operation member 415 is illegally operated from the back side of the pachinko machine 10 when the inner frame 12 is closed. It is possible to prevent fraudulent acts by inserting tools or hands.

  In addition, the outer frame 11 has its operation portion 415d facing the operation portion 415d together with the heel base 414 in the sliding direction view of the operating member 415 in a state where the inner frame 12 is closed (perpendicular to the plane of FIG. 20). It is formed in a surrounding shape. For this reason, when the inner frame 12 is opened with respect to the outer frame 11, the diagonally rear side (lower left side in FIG. 20) of the operation unit 415 d that the inner frame 12 is facing is located between the inner frame 12 and the outer frame 11. The operator can operate the operation member 415 by operating the operation unit 415d. Therefore, when the inner frame 12 is opened, the operating member 415 can be easily operated to open the front frame set 14. Further, in the state where the inner frame 12 is closed (the state shown in FIG. 20), the operation portion 415d is surrounded by the outer frame 11 and the collar base 414 when viewed in the sliding direction of the operating member 415. The part where the part 415d is exposed is reduced, and an illegal act on the operating member 415 can be prevented. Note that the gap between the tip of the rib 415c of the operating member 415 and the convex portion 11b of the outer frame 11 is a part caused by dimensional variation in manufacturing the parts, and is not necessarily required, and is not necessary at the tip of the rib 415c of the operating member 415. The protrusion 11b of the outer frame 11 may abut or the tip of the rib 415c of the actuating member 415 and the protrusion 11b of the outer frame 11 may overlap each other.

  Further, as described above, the heel base 414 is formed by bending a metal plate, and extends in a direction perpendicular to the main plate 414a attached to the inner frame 12 and one end side of the main plate 414a. A side plate 414b and a rib 414c that protrudes in parallel with the main plate 414a in the same direction from the tip of the side plate 414b and surrounds the operating member 415 are provided. By this rib 414c, the part where the operating member 415 is exposed on the back side of the pachinko machine 10 is reduced, and it is possible to further prevent unauthorized operation on the operating member 415. In addition, it is preferable that the rib 414c is provided in the site | part in which the operation part 415d of the action | operation member 415 is formed at least. Since the operation unit 415d is a part formed to facilitate the operation of the operating member 415, the operation part 415 is made difficult to touch, thereby effectively preventing an illegal act while improving workability for the operating member 415. be able to.

  Here, as shown in FIG. 15, the lower end portion 415b1 of the first engagement groove 415b of the operating member 415 protrudes so as to contact the first arm portion 452a of the cam 452 when the operating member 415 moves upward. Is formed. Therefore, when the cam 452 is not rotated, that is, when the dedicated key K is not operated, the actuating member 415 does not move upward by a certain amount and the inner frame collar member 411 is opened. In order to move to the position, it is necessary to operate the dedicated key K. If the inner frame 12 is opened in a state where the pachinko machine 10 is installed in the amusement hall, a fraudulent act that is difficult to detect later, such as illegally replacing a board or the like disposed on the back side of the pachinko machine 10 However, since the dedicated key K is always required for the operation of the inner frame collar member 411, the security can be improved.

  Next, an operation example of the operation member 415 with respect to the operation unit 415d will be described. If the pachinko machine 10 breaks down during the game, the player calls a store clerk and requests a return to the normal state. An operator such as a store clerk opens the front frame set 14 provided with the glass 137 to check the abnormal state, and if it still cannot return to the normal state, the inner frame 12 is opened to the front side to open the pachinko machine 10. Check the backside of the board for missing connectors, etc., game ball outlets and clogged balls around the winning hole.

  When working on the back side of the inner frame 12, if the front frame set 14 is left open with respect to the inner frame 12, the front frame set 14 can be used even if the operator works while supporting the inner frame 12. It can swing freely. Since a plurality of pachinko machines 10 are installed side by side in the amusement hall, an accident may occur in which the front frame set 14 collides with a player who is playing a game next to the inner frame 12 with the momentum. If there is such an accident, the player will feel uncomfortable and the reputation of the playground will be reduced. It is preferable to carry out. In addition, when the worker is distracted by the work on the back side of the inner frame 12, it is possible that the winning is easily generated by changing the arrangement of the nails placed on the gaming board 30 illegally. . For this reason, it is also preferable to ensure safety and crime prevention by keeping the front frame set 14 closed while the worker is working on the back side of the inner frame 12. In addition, it is preferable for the operator to thoroughly work so that the dedicated key K is extracted every time the front frame set 14 is opened or the inner frame 12 is opened, so that the dedicated key K is stolen. In other words, it is possible to prevent fraudulent acts such as an illegal key K being produced by taking the type of the dedicated key K.

  For the above reasons, the inner frame 12 may be opened and work may be performed on the back side thereof with the front frame set 14 closed and the dedicated key K removed. In this case, after the work on the back side of the inner frame 12 is completed, the operator opens the front frame set 14 again to confirm that it has returned to the normal state, and confirms the operation for winning a prize at the winning opening. The confirmation work is performed. At this time, when the front frame set 14 is closed, it is troublesome to insert the dedicated key K again into the key hole and perform the opening operation. According to the pachinko machine 10, since the operation unit 415d of the work member 415 is not covered with the outer frame 11 in a state where the inner frame 12 is opened, the operation with the dedicated key K is performed by operating the operation unit 415d. The front frame set 14 can be opened without the need. Therefore, by providing the operation unit 415d, the confirmation work after the inspection work can be performed easily and quickly.

  Next, the lower plate cage member 413 for closing the lower plate unit 13 will be described with reference to FIGS. 13, 21, and 22. FIG. 21 is a side view of the lower plate ridge member 413, and FIG. 22 is a cross-sectional view of the locking unit 410 taken along the line Sc-Sc in FIG. In FIG. 22, only the main members related to the operation of the lower plate bowl member 413 are shown, and the others are omitted.

  As described above, the locking unit 410 engages with a receiving metal fitting 403 (see FIG. 2) provided on the lower plate unit 13 in order to lock the lower plate unit 13, and opens the lower plate unit 13 in the opening direction. A lower plate ridge member 413 that restricts the movement and closes is provided. As shown in FIG. 21, the lower plate ridge member 413 has a base 413c provided with two support holes 413b that are substantially the same width as the side plate 414b of the ridge substrate 414 and are formed long along the longitudinal direction of the ridge substrate 414. An engaging claw 413a that protrudes from the base portion 413c to the front side of the pachinko machine 10 and engages the receiving metal fitting 403, and a mounted portion 413d that protrudes from the base portion 413c to the back side of the pachinko machine 10 and has a coil spring 423 installed thereon And an operating portion 413e that is formed in a longitudinal direction of the support hole 413b and intersects with the sliding direction of the lower plate bowl member 413 and protrudes to the front side of the pachinko machine 10.

  As shown in FIG. 13, the lower plate bowl member 413 is stretched and urged upward by a coil spring 423 installed on the installation portion 413d. The position that is biased upward and engages with the receiving metal fitting 403 is the closing position of the lower plate cage member 413, and moves downward with respect to the receiving metal fitting 403 to release the engagement with the receiving metal fitting 403. The position becomes the open position.

  Here, the inner frame 12 includes an opening 12d that is an area overlapping the front frame set 14 and communicates from the front side of the inner frame 12 where the front frame set 14 is disposed to the back side of the inner frame 12 ( 3), the saddle base 414 is attached to a position where the operation portion 413e protrudes from the opening 12d, and the operation portion 413e can be operated by pressing through the opening 12d. Since the eaves base 414 is provided not on the front side where the front frame set 14 is provided but on the back side thereof, the front frame set 14 and the inner frame 12 are used to close the eaves base 414 when the front frame set 14 is closed. Is covered. Therefore, the eaves members 411 to 413 and the like supported by the eaves base 414 can be made difficult to touch illegally, and crime prevention against illegal acts can be improved. In addition, since the operation portion 413e of the lower plate cage member 413 can be operated through the opening 12d of the inner frame 12, the operator operates the operation portion 413e to close the lower plate cage member 413. To the open position side. In addition, since the operation portion 413e of the lower plate ridge member 413 is formed to protrude to the front side of the pachinko machine 10 that intersects the slide direction, the lower plate ridge member 413 can be easily placed on the operator and moved to the open position. Can be moved easily.

  Further, the operation portion 413e of the lower plate ridge member 413 is formed at a position on the front side of the inner frame 12 so as to overlap the front frame set 14 in a state closed by the interlocking ridge member. For this reason, in the state where the front frame set 14 is closed, the operation unit 413e of the lower plate ridge member 413 is covered with the front frame set 14, and the operator cannot operate the operation unit 413e. When the front frame set 14 is opened, the operation unit 413e is exposed, so that the operator can easily see the operation unit 413e and can operate the operation unit 413e. Therefore, after the front frame set 14 is opened, the lower plate unit 13 can be easily opened using the operation unit 413e without performing a special operation using the dedicated key K for the cylinder lock 450. Can do. Therefore, the operator can easily perform the opening operation of the front frame set 14 using the dedicated key K and the opening operation of the lower plate unit 13 performed without using the dedicated key K. It is possible to improve the workability at the time of inspection work requiring opening of the door.

  Further, the operation portion 413e of the lower plate ridge member 413 is formed to protrude from the support hole 413b supported by the side plate 414b of the ridge base 414 to the front side of the inner frame 12. For this reason, the operation unit 413e is disposed close to the front side of the inner frame 12 where the front frame set 14 is disposed, and the operation unit 413e can be easily operated when the front frame set 14 is opened. .

  In addition, the inner frame 12 is provided with a game board 30 that forms a game area on which the game ball flows down on one surface side of the inner frame 12, and the front frame set 14 is disposed so as to overlap the game area. The lower tray unit 13 is disposed at a position that does not overlap the game area. In the game area, even after the pachinko machine 10 is installed in the game hall, it is necessary to perform work when the game ball is caught or when the arrangement position of a nail, a windmill, or the like that forms the flow path of the game ball is adjusted. The front frame set 14 that overlaps the game area can be opened by the unlocking operation with the dedicated key K, while the lower plate unit 13 cannot be opened without the front frame set 14 being opened. The opening operation of the part which needs to be performed can be simplified.

  At the upper end of the lower plate unit 13, there is a protruding portion 13 a (see FIG. 2) that is located on the back side of the front frame set 14 and partially overlaps when the lower plate unit 13 and the front frame set 14 are closed. Provided. For this reason, as described above, a part of the lower tray unit 13 is arranged to face each other while overlapping the closing direction side in the closed state of the front frame set 14, and the opening of the front frame set 14 is the lower tray. This is a necessary condition for opening the unit 13. Here, when the operation portion 413e of the lower plate ridge member 413 is exposed, the front frame set 14 is opened. For this reason, in a state where the operation unit 413e is exposed, the front frame set 14 moves to the opening direction side and the movement of the lower pan unit 13 to the opening direction side is not prevented, and the operation unit 413e can be operated. In this case, it is not necessary for the operator to be aware of the engagement between the lower plate unit 13 and the front frame set 14, and workability such as inspection work performed by opening the lower plate unit 13 can be improved.

  In addition, the front frame collar member 412 for closing the front frame set 14 is provided at two positions, upper and lower, and each front frame collar member 412 is configured to be separately slidable from the closed position to the open position. The bowl member 413 is formed of a single member in which engaging claws (ridge portions) 413 a that engage with the receiving metal fitting 403 of the lower plate unit 13 are formed at two upper and lower portions. For this reason, it is difficult to illegally open the front frame set 14 closed by the front frame flange member 412. On the other hand, since the lower plate unit 13 closed by the lower plate ridge member 413 is a single member having a plurality of ridge portions engaged therewith, a plurality of lower plate ridge members 413 are provided. The structure is simplified compared to the above, and the manufacturing cost of the lower plate ridge member 413 is reduced. Here, the operation unit 413e that is operated by the operator when the lower plate unit 13 is opened is provided in a portion exposed by opening the front frame set 14, and therefore, a plurality of front frame ridge members 412 are illegal. The operation unit 413e is disposed at a position where it is difficult to open the screen. Therefore, it is possible to reduce the manufacturing cost of the lower plate ridge member 413 while making an illegal act to open the lower plate unit 13 difficult.

  Further, the cylinder lock 450 and the lower plate bowl member 413 (the engaging claw 413a thereof) protrude outward from the main plate 414a of the bowl base 414 (left side of FIG. 13A) as shown in FIG. 13A. Is formed. The inner frame 12 is provided with an opening (not shown) through which the projecting portion is inserted, and the operation portion 413e of the lower plate bowl member 413 is connected to the main plate 414a of the bowl base 414. The cylinder lock 450 and the engaging claw 413a of the lower plate bowl member 413 are formed at a position overlapping the front side of the pachinko machine 10 (the rear side in the direction perpendicular to the paper surface in FIG. 13B). For this reason, the assembly space required for assembling the locking unit 410 unitized by the heel base 414 straightly from the back side to the front side of the pachinko machine 10 to the inner frame 12 is the assembly of the main plate 414a of the heel base 414. Overlap with space. Therefore, as compared with the case where the operation portion 413e is formed so as to protrude to the side deviated from the front side of the main plate 414a (for example, the right side in FIG. 13B), the assembly space associated with the setting of the operation portion 413e is increased. Can be suppressed. Thereby, while being able to make other component layout with respect to the back surface side of the inner frame 12 easy, workability | operativity when attaching the locking unit 410 to the inner frame 12 can be improved. The operation portion 413e is preferably formed so that at least a part thereof overlaps the main plate 414a of the base body 414 on the side from which the cylinder lock 450 or the lower plate collar member 413 protrudes. It is preferable that the flange member 413 is formed so as to overlap with the protruding side.

  The lower tray unit 13 is provided with a game ball launching handle 18 on which an operation related to the game is performed by the player. The game area where game balls flow down and the storage area where game balls for payout are stored are areas where game balls are likely to be clogged and frequently require inspection work. There are few occurrences, and the number of inspection work etc. is small. The lower plate unit 13 of the pachinko machine 10 is provided with a game ball launching handle 18 so that the front frame set 14 can be opened while the lower plate unit 13 is closed. The front frame set 14 can be opened without opening the vicinity of the handle 18. Therefore, even if the front frame set 14 covers a game area where the frequency of inspection work is high, the area opened on the front side of the inner frame 12 can be reduced and the size of the front frame set 14 can be reduced. The workability of the work involving the opening can be improved.

  As shown in FIG. 22, the coil spring 423 installed on the lower plate bowl member 413 is disposed on the distal end side (right side in FIG. 22) of the side plate 414 b of the bowl base 414. For this reason, when attaching the saddle base to the inner frame 12 along the surface direction of the main plate 414a, the coil spring 423 is positioned on the rear end side along the attachment direction, and other members than those on the front end side. Thus, the coil spring 423 is less likely to come into contact with the coil spring 423 and can be less likely to be damaged during assembly.

  The coil spring 423 is disposed so as to protrude to the outside (upper side in FIG. 22) of the side plate 414b of the bowl base 414. The lower plate bowl member 413 has one end side (right side in FIG. 22) of its base 413c. A return portion 413f that is bent so as to largely protrude from the coil spring 423 to the outside of the side plate 414b is provided. For this reason, when attaching the saddle base 414 to the inner frame 12, the return portion 413f easily collides with other members before the coil spring 423 collides, and the return portion 413f further prevents damage to the non-interlocking saddle biasing means. it can.

  The mounted portion 413d and the return portion 413f of the lower plate bowl member 413 are formed so as to protrude from the back side of the pachinko machine 10 with respect to the base portion 413c. For this reason, compared with the case where it is formed to protrude in different directions, it is easy to bring the necessary part closer, the yield of the material can be improved, and the part cost can be reduced. Further, since the mounted portion 413d is formed so as to protrude from the base portion 413c, the size of the base portion 413c can be reduced as compared with the case where the mounted portion is formed by cutting out the base portion 413c. While increasing the strength, the size is made compact to increase the freedom of design layout.

  Further, the lower plate ridge member 413 is slidably supported by a guide pin 433 that slidably supports one end part of the ridge base 414 to slidably support the other part, and a support through which the guide pin 433 is inserted. Both ends of the hole 412a are stoppers that contact the guide pin 433. For this reason, the hole formed for inserting the guide pin 433 into the bowl base 414 or the lower dish bowl member 413 can be made to a minimum length, and the strength reduction accompanying the formation of the hole can be reduced. A part to be unitized by the base body 414 can be reduced in size to increase the degree of freedom in design layout.

  Similarly to the inner frame ridge member 411, the front frame ridge member 412, and the operating member 414, the lower plate ridge member 413 slides along the longitudinal direction of the ridge base 414, that is, the vertical direction of the pachinko machine 10. It is supported movably. For this reason, the flange base 414 can support the flange members 411 to 413 and the like while narrowing the lateral width intersecting the longitudinal direction. Therefore, the space required for attaching the saddle base can be reduced, the design layout around the locking unit 410 integrated by the saddle base 414 can be facilitated, and the degree of freedom with respect to the arrangement of peripheral components can be increased.

  Next, an assembling operation for attaching the locking unit 410 to the inner frame 12 will be described. First, the inner frame eaves member 411, the front frame eaves member 412, the lower plate eaves member 413, the coil spring, and other members are sequentially assembled to the eaves base 414, and these are integrated (unitized) into the eaves base 414. Thus, the locking unit 410 shown in FIG. 13 is manufactured. Thereafter, the heel base 414 is brought close to the back surface side of the inner frame 12, the locking unit 410 is aligned with a fixed position on the back surface of the inner frame 12, and screws are inserted into a plurality of holes provided in the heel base 414. The locking unit 410 is attached to the back side of the.

  As described above, in the pachinko machine 10, before the assembly work is performed, the inner frame ridge member 411, the front frame ridge member 412, the lower plate ridge member 413, and the coil spring are set to a relative position corresponding to a predetermined assembly position. The inner frame 12 may be simply attached to the inner frame 12 at a fixed position. Therefore, as compared with the case where the flange members 411 to 413 are separately attached to the inner frame 12, the locking unit 410 is manufactured in a place where the work space is sufficient, and the work to be performed on the back side of the inner frame 12 is reduced. Therefore, the assembly workability can be improved and the manufacturing cost can be reduced.

  Next, the first control board unit 201 will be described with reference to FIGS. FIG. 23 is a front view of the first control board unit 201, FIG. 24 is a perspective view of the unit 201, FIG. 25 is an exploded perspective view of the unit 201, and FIG. FIG.

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and the main control device 261 and the sound lamp control device 262 are mounted on the mounting base 251. Here, the main control device 261 is an MPU 501 (see FIG. 33) as a one-chip microcomputer for controlling the main game, a port for communicating with various devices, a random number generator used for various lotteries, a time count, It has a main board including a clock pulse generating circuit used for synchronization, etc., and this main board is housed in a board box 263 (encapsulating means) made of a transparent resin material or the like. . The substrate box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected to each other by a sealing unit 264 (sealing means) so that the substrate box 263 is sealed.

  As long as the sealing unit 264 is configured to connect the box base and the box cover so that they cannot be unsealed, any configuration can be applied. Here, as shown in FIG. 24 and the like, five sealing members are connected. The box base and the box cover are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. The sealing process by the sealing unit 264 prevents unauthorized opening after the sealing, and makes it possible to detect such a situation early and easily even if the unauthorized opening is performed. It is possible to perform the opening / sealing process again even after the operation. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit 264. And when opening the board | substrate box 263 by the malfunction of the accommodated main board | substrate etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, a locking claw is inserted into the long hole of another sealing member. If the history of opening the substrate box 263 is left in the substrate box 263, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 263.

  The sound lamp control device 262 includes an MPU as a one-chip microcomputer for controlling sound and lamp display according to instructions from the main control device 261 or the display control device 45, and a sound lamp control board including various ports. The sound lamp control board is housed in a board box 265 made of a transparent resin material or the like. A power relay board 266 is mounted on the sound lamp control device 262, and power supplied from a power board described later is output to the display control device 45 and the sound lamp control device 262 via the power relay board 266. .

  The mounting base 251 is formed of a colored (for example, green, blue, etc.) resin material (for example, made of polycarbonate resin), and has two substrate mounting surfaces 252 and 253 that are flat on the surface. These substrate mounting surfaces 252 and 253 extend in a direction orthogonal to each other and are formed with a step in the front-rear direction. However, the mounting base 251 may be a colorless transparent or translucent resin molded product.

  On one board mounting surface 252, the main control device 261 is arranged in a landscape orientation, and on the other board mounting surface 253, an audio lamp control device 262 (audio lamp control board) is oriented in a portrait orientation. Be placed. In particular, the main control device 261 is disposed on the near side when viewed from the back of the pachinko machine 10, and the sound lamp control device 262 is disposed on the back side. In this case, since the substrate mounting surfaces 252 and 253 are formed with steps in the front-rear direction, the control devices 261 and 262 are mounted in a state where the main controller 261 and the sound lamp controller 262 are mounted on the substrate mounting surfaces 252 and 253. Are arranged with a part of them stacked one after the other. That is, as can be seen in FIG. 24 and the like, the main controller 261 is arranged in a state where a part thereof (about 1/3 in the present embodiment) is floated. Therefore, the sound lamp control device 262 can be expanded to an area overlapping with the main control device 261, and it is possible to cope with an increase in the size of the control board and to install each control device efficiently. Further, in a state where the first control board unit 201 is mounted on the game board 30, a space is secured behind the board mounting surface 252, and the variable winning device 32 and its electric wiring can be installed without difficulty.

  As shown in FIGS. 25 and 26, the board mounting surface 252 for the main board is formed with horizontally elongated through holes 254 at two places on the left and right. Correspondingly, the substrate box 263 of the main control device 261 is provided with rotating fixtures 267 at two places on the left and right sides of the back surface thereof. When the main controller 261 is mounted on the board mounting surface 252, the fixing tool 267 is passed through the through hole 254 of the board mounting surface 252, and the fixing tool 267 is rotated in this state to lock the main control apparatus 261. The Therefore, even if the main control device 261 is arranged with a part thereof floating as described above, inconveniences such as dropping off of the main control device 261 can be avoided. Further, since the main control device 261 cannot be removed unless the fixture 267 is unlocked from the back side of the first control board unit 201 (board mounting surface 252), it is expected to have a deterrent effect against illegal acts such as board removal. it can. A grid-like rib 255 is provided on the back surface of the substrate mounting surface 252 for the main substrate.

  The mounting base 251 is provided with a pair of upper and lower support shafts 256 on the left end surface of FIG. 24 and the like.

The payout control device 311, the launch control device 312, and the power supply device 313 have a control board including an MPU as a one-chip microcomputer that forms the center of control, various ports, and the like, as is well known. Thus, the payout of prize balls and rental balls is controlled. The launch control board of the launch control apparatus 312 controls the launch solenoid 229 in accordance with the operation of the game ball launch handle 18 by the player, and the power board of the power supply apparatus 313 provides a predetermined power source required for various control apparatuses and the like. A voltage is generated and output. The card unit connection board 314 is electrically connected to the ball lending operation unit 120 on the front surface of the pachinko machine 10 and a card unit (not shown). Is. Note that the card unit connection board 314 is not necessary in a cash machine in which game balls are rented directly from the ball lending device or the like to the upper plate without using a card unit.

  The payout control device 311, the firing control device 312, the power supply device 313, and the card unit connection substrate 314 are respectively configured to be accommodated in substrate boxes 315, 316, 317, and 318 made of a transparent resin material or the like. In particular, in the dispensing control device 311, similarly to the main control device 261 described above, the box base and the box cover constituting the substrate box 315 (encapsulating means) are connected by the sealing unit 319 (sealing means) so that they cannot be opened. Thus, the substrate box 315 is sealed.

  The payout control device 311 is provided with a state return switch 321. For example, when the state return switch 321 is pressed when a payout error occurs, such as a ball clogged in the payout motor 358a, the payout motor 358a rotates forward and backward to eliminate the ball clogging (return to the normal state). It is like that.

  The power supply device 313 is provided with a RAM erase switch 323. This pachinko machine 10 has a backup function, so that even if a power failure occurs, it maintains the state at the time of a power failure, and can be restored to the state at the time of a power failure when returning from a power failure (power recovery) It has become. Therefore, if the power is turned off in the normal procedure (for example, when the hall is closed), the state before the power is turned off is stored. If you want to return to the initial state when the power is turned on, turn on the power while pressing the RAM erase switch 323. To do.

  The mounting base 301 is made of, for example, a colorless and transparent resin molded product, and a flat board mounting surface 302 is provided on the surface thereof.

It is fixed to the frame 12 so that it cannot be opened and closed. The support hole 237 and the support shaft 305 correspond to the support shaft portion M4 in FIG. 8, and the fastened hole 239 and the ny latch 306 correspond to the fastening portion M5, respectively.

  Next, the configuration of the back pack unit 203 will be described with reference to FIGS. 30 and 31. The back pack unit 203 is formed by integrating a resin-molded back pack 351 and a game ball payout mechanism 352. FIG. FIG. 31 shows an exploded perspective view thereof.

  The back pack 351 is integrally formed of, for example, ABS resin, and includes a substantially flat base portion 353 and a protective cover portion 354 that protrudes rearward from the pachinko machine 10 and has a horizontally long substantially rectangular parallelepiped shape. The protective cover portion 354 has a shape in which the left and right side surfaces and the upper surface are closed and only the lower surface is opened, and has a size sufficient to surround at least the variable display device unit 35. The lamp control device 262 is also enclosed. A large number of ventilation holes 354 a are provided on the back surface of the protective cover portion 354. Each of the air holes 354a has a long hole shape, and the air holes 354a are adjacent to each other at a relatively close position. Therefore, the back surface of the back pack 351 can be easily opened by cutting the resin portion between the adjacent vent holes 354a. That is, a predetermined test or the like can be easily performed by cutting the resin portion between the vent holes 354a to expose the display control device 45 and the like inside.

  In addition, a payout mechanism portion 352 is disposed on the base portion 353 so as to bypass the protective cover portion 354. That is, a tank 355 opened upward is provided at the uppermost portion of the back pack 351, and game balls supplied from the island equipment of the game hall are sequentially replenished to the tank 355. Below the tank 355, for example, a tank rail 356 having two rows (two rows) of spherical passages and gently inclined toward the downstream side is connected. Further, the tank rail 356 is vertically oriented downstream of the tank rail 356. A case rail 357 is connected.

  Here, with reference to FIG. 34, the display content of the large symbol display apparatus 42 is demonstrated. The large symbol display device 42 displays three symbol rows of left, middle, and right. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-pattern made up of, for example, rhombus-shaped symbols. Each of the main symbols and sub-designs represents a large symbol. It is composed. In each symbol row, main symbols are arranged in ascending or descending numerical order, and sub-designs are arranged between the main symbols. That is, each symbol row is provided with a total of 20 large symbols of 10 main symbols and 10 sub symbols, and 20 large symbols scroll periodically from top to bottom for each symbol row. It is displayed in a variable manner. In particular, the numbers of the main symbols are arranged so that they 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 large symbol display device 42 displays large symbols in three stages of upper, middle, and lower for each symbol row. Accordingly, the large symbol display device 42 displays a total of nine large symbols in 3 rows × 3 columns. The large symbol display device 42 has 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. 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) A big hit video will be displayed as a big hit if you align.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 501 in the main control device 261 uses various counter information during the game to perform a jackpot lottery, a symbol display setting of the large symbol display device 42, and the like. As shown in FIG. 35, 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 big game symbol display device 42, and the reach lottery when the big symbol symbol display device 42 changes and changes. Reach random number counter C3 used for the initial value setting, random number initial value counter CINI used for initial value setting of the jackpot random number counter C1, variation type counters CS1 and CS2 used for variation pattern selection of the large symbol display device 42, the left column, The left, middle, and right out symbol counters CL, CM, and CR used to set each out symbol in the middle and right columns It is set to be there. A small symbol random number counter C4 is used for the lottery of the small symbol display device 41.

  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 the R register (refresh register) in the MPU 501, and as a result, the 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), and in each of these areas, game balls to the big game mouth 33 are provided. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in accordance with the winning timing.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated within the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once every timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The big hit random number counter C1 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 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”. High probability means a state in which the combination of large symbols becomes a big hit by a predetermined combination of probability fluctuation symbols and the subsequent jackpot probability is increased as added value, so-called probability change. (Time) means a time when such a state of probability is not met.

  The jackpot symbol counter C2 determines a symbol when the fluctuation of the large symbol display device 42 is stopped in the case of a jackpot. In the present embodiment, the large symbol symbol display device 42 has five effective lines, and a specific symbol is selected. Since 10 types of (main symbols) are set, 50 counter values (0 to 49) are prepared. In other words, the jackpot symbol counter C2 is incremented one by one within the range of 0 to 49, and after reaching the maximum value (ie 49), returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 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 out” and stop “complete out” that does not occur reach. For example, the reach random number counter C3 = 0, 1 corresponds to the front / rear out of reach, the reach random number counter C3 = 2-21 corresponds to the reach other than the front / rear out, and the reach random number counter C3 = 22-238 corresponds to the complete out. Note that the reach lottery may be set individually according to the state of the lottery probability of the big symbol display device 42, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the big game mouth 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 returns to 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 large symbols such as so-called normal reach, super reach, premium reach, and other general symbol variation modes, and the second variation type counter CS2 determines the final stop symbol (the book) In the embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. The buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the variation of the large symbol is started by the large symbol display device 42.

  The left, middle and right off symbol counters CL, CM, and CR are used to determine the left column large symbol symbol, middle column large symbol symbol, and right column large symbol symbol when the big hit lottery is off. Yes, in each column, any of the 20 large symbols including the main symbol and the sub symbol is displayed, 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 numerical value of the R register built in the MPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, the current value is determined by subtracting 20. 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 the variation of the large symbol, the buffer value of any one of the front / rear reach symbol buffer, the reach symbol buffer other than front / rear out, and the completely out symbol buffer is acquired according to the value of the reach random number counter C3. .

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, 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.

  The accessory 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 accessory symbol random number counter C4 is periodically updated (once every timer interruption in this embodiment), and is acquired when it is detected that the game ball has passed through the accessory gate (through gate) 34 on either the left or right side. Is done. 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 MPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. 36 to 43. The MPU 501 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 milliseconds (hereinafter referred to as “ms”)). And an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 41 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 501 of the main controller 261 every 2 ms, for example. In the timer interruption process, first, reading process of various winning switches is executed (S601). That is, the state of various switches (except for the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI is updated (S602). 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.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are updated (S603). 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. After that, a start winning process is performed in accordance with winning in the big mouth 33 (S604).

  This start winning process will be described with reference to the flowchart of FIG. First, it is determined from the detection information of the operation port switch 224 whether or not the game ball has won the big game mouth 33 (start winning prize) (S701). When it is determined that the game ball has won the big game mouth 33 (S701: Yes), it is determined whether or not the number N of active reserved balls of the big game symbol display device 42 is less than the upper limit value (4 in the present embodiment). (S702). If there is a prize at the big mouth 33 and the number N of activated balls is less than 4 (S702: Yes), the number N of activated balls is incremented by 1 (S703), and the jackpot random number counter updated in step S603 is further added. The respective values of C1, jackpot symbol counter C2 and reach random number counter C3 are stored in the first area among the empty reserved areas in the reserved ball storage area of RAM 503 (S704). On the other hand, if there is no winning at the big mouth 33 (S701: No), or even if there is a winning at the big mouth 33, if the operation holding ball number N <4 is not satisfied (S702: No), each of S703 and S704 The process is skipped and the start winning process is terminated. After the start winning process is completed, the MPU 501 once ends this timer interrupt process.

  When the game ball wins the big game mouth 33 (start winning prize), the big game symbol display device 42 starts to display the fluctuation of the big game symbol, but after the winning prize, the big game symbol changes and the symbol stops. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before reaching. 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 (S704). Specifically, since the start winning process is executed at a cycle of 2 ms, 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 a variation pattern of a large symbol, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time elapses).

  FIG. 43 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 501 of the main controller 261 when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. By this NMI interruption process, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the MPU 501 in the main controller 261, and the MPU 501 interrupts the control being executed. NMI interrupt processing is started. The NMI interrupt processing program in FIG. 43 is stored in the ROM 502 of the main controller 261. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 541 so that the processing of the main controller 261 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt process, first, the used register is saved in the backup area 503a of the RAM 503 (S801), and the value of the stack pointer is stored in the backup area 503a (S802). Further, the occurrence information of the power shutdown is set in the backup area 503a (S803), and a power shutdown notification command indicating that the power is shut off is transmitted to another control device (S804). A RAM determination value is calculated and stored in the backup area 503a (S805). The RAM determination value is, for example, a checksum value at the work area address of the RAM 503. Thereafter, access to the RAM 503 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and processing cannot be executed.

  The above NMI interrupt process is executed in the same manner in the payout control apparatus 311. With this NMI interrupt process, the state of the payout control apparatus 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Is done. Similarly, power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 542 to the NMI terminal of the MPU 511 in the payout controller 311 and the MPU 511 interrupts the control being executed. Then, the NMI interrupt process of FIG. 43 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 36 is a flowchart showing a main process executed by the MPU 501 in the main controller 261. This main process is started by a reset at power-on. In the main process, first, an initial setting process associated with power-on is executed (S101). Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (audio lamp control device 262, payout control device 311, etc.) to become operable, Wait processing (for example, about 1 second) is executed. After a payout permission command is transmitted to the payout control device 311 (S102), access to the RAM 503 is permitted (S103).

  Thereafter, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is turned on (S104), and if it is turned on (S104: Yes), processing is performed to clear (erase) the backup data. The process proceeds to S114. On the other hand, if the RAM erasing switch 323 is not turned on (S104: No), it is further determined whether or not the information on the occurrence of power interruption is stored in the backup area 503a of the RAM 503 (S105). (S105: No), since backup data is not stored, in this case as well, the process proceeds to S114. If the occurrence information of power shutdown is stored in the backup area 503a (S105: Yes), a RAM judgment value is calculated (S106), and if the calculated RAM judgment value is not normal (S107: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S114. As described above, the RAM determination value is a checksum value at a work area address of the RAM 503, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 503 is 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 RAM initialization processing (S114 to S116). Similarly, when the information on occurrence of power shutdown is not set, or when a backup abnormality is confirmed by a RAM determination value (checksum value or the like), the process proceeds to initialization processing (S114 to S116) of the RAM 503 in the same manner. That is, in the RAM initialization process from S114, the used area of the RAM 503 is cleared to 0 (S114), and the initial value of the RAM 503 is set (S115). Thereafter, the interrupt is permitted (S116), and the process proceeds to normal processing described later.

  On the other hand, if the RAM erasure switch 323 is not turned on (S104: No), the information on the occurrence of power shutdown is stored (S105: Yes), and the RAM judgment value (checksum value etc.) is normal ( (S107: Yes), the process proceeds to S108, and a process at the time of power recovery (a process at the time of power-off restoration) is executed. That is, in the power recovery process, the stack pointer at the time of power interruption is restored (S108), and the information on occurrence of power interruption is cleared (S109). Next, a power-return command for returning the sub-side control device to the gaming state at the time of power-off is transmitted (S110), and the used register is returned from the backup area 503a of the RAM 503 (S111). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S112). If the interrupt is permitted (S112: Yes), the interrupt is permitted (S113), while the interrupt is prohibited when the power is turned off. If it is in the state (S112: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, 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, each process of S201 to S207 is executed as a periodic process with a period of 4 ms, and the counter update process of S209 and S210 is executed in the remaining time.

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 45 when the large symbol display device 42 displays the variation of the large symbol symbol. In addition, after the start of large symbol variation, one each time in the normal process in the order of variation pattern command → stop symbol command of the left symbol sequence → stop symbol command of middle symbol sequence → stop symbol command of the right symbol sequence (that is, one each in the order of normal processing) The command is transmitted once every 4 ms), and the confirmation command is transmitted at the end of the fluctuation time.

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

  Here, with reference to FIG. 38, the off symbol counter update process will be described. First, it is determined whether or not it is time to update the left symbol row out symbol counter CL (S301). If it is the update time (S301: Yes), the out symbol symbol CL out of the left symbol row is updated (S303). Next, if it is not the update time of the left symbol row (S301: No), it is determined whether or not it is the update time of the out-of-middle symbol row symbol counter CM (S302), and if it is the update time (S302: Yes), The out symbol counter CM of the middle symbol row is updated (S304). Furthermore, if it is not the update time of the middle symbol row (S302: No), it is the update timing of the right symbol row, so the outlier symbol counter CR of the right symbol row is updated (S305).

  In updating outlier symbol counters CL, CM, and CR in each of the processes of S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is added when the addition result exceeds the maximum value. Subtraction is performed, and the result of the calculation is taken as the current value of the symbol counters CL, CM, CR. According to the update process of CL, CM, CR, the outlier counters CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row are sequentially updated one by one in one normal process. The update time of each counter value does not overlap. Thus, every time the normal process is executed three times, the set symbol counters CL, CM, and CR are updated for one set.

  Thereafter, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination (S306). If the symbol combination is a jackpot symbol combination (S306: Yes), this processing is performed as it is. finish. If it is not a jackpot symbol combination (S306: No), it is determined whether it is a reach symbol combination (S307). It is determined whether or not there is (S308). If it is a combination of front and rear detach reach (S308: Yes), the combination of the detachment symbol counters CL, CM and CR at that time is stored in the front and rear detach reach symbol buffer of the RAM 503 (S309). If the out symbol counters CL, CM, CR are combinations other than front / rear out of reach (S308: No), the combination of out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer except for front / rear out of RAM 503 (S310). ). If the combination of the off symbol counters CL, CM, CR is not a jackpot symbol combination (S306: No) and is not a reach symbol combination (S307: No), the combination of the off symbol counters CL, CM, CR is an off symbol. In such a case, the combination of the off symbol counters CL, CM, CR is stored in the complete off symbol buffer of the RAM 503 (S311).

  After the off symbol counter CL, CM, CR update process (S203) is completed, the process returns to the normal process of FIG. 37, and the prize ball counting signal and the payout abnormality signal received from the payout control device 311 are read (S204). A large symbol variation process for performing variation display of a large symbol on the display device 42 is executed (S205). By this big game symbol variation processing, jackpot determination, large symbol variation pattern setting, and the like are performed. Details of the large symbol variation process will be described later with reference to FIG.

  After the big symbol variation process is completed, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 32 is executed in the case of the big hit state (S206). That is, the big winning opening is opened for each round of the big hit state, and it is determined whether the maximum opening time of the big winning opening has elapsed 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.

  Next, display control of the accessory symbol (eg, “O” or “X” accessory symbol) by the accessory symbol display device 41 is executed (S207). Briefly, on the condition that the game ball has passed the accessory gate (through gate) 34, the value of the accessory symbol random number counter C4 is acquired each time and the accessory 43 is displayed on the accessory symbol display device 41. Symbol variation display is performed. Then, a small symbol drawing is performed according to the value of the small symbol random number counter C4, and when the small symbol wins, the electric accessory associated with the big mouth 33 is released for a predetermined time. Although illustration is omitted, the small symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 41, like the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3.

  Thereafter, it is determined whether or not the next normal process execution timing has been reached, that is, whether or not a predetermined time (4 ms in the present embodiment) has elapsed since the start of the previous normal process (S208). If (S208: Yes), the process proceeds to S201, and the processes after S201 described above are repeatedly executed.

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal processing (S208: No), the random number initial is within the remaining time until the predetermined time is reached, that is, until the next normal processing execution timing. The value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated (S209, S210). First, the random number initial value counter CINI is updated (S209). 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. Next, the fluctuation type counters CS1 and CS2 are updated (S210). 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 S201-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 large symbol variation process (S205) will be described with reference to the flowcharts of FIGS. In the large symbol variation process, first, it is determined whether or not a big hit is currently being made (S401). The jackpot includes a jackpot game displayed on the big symbol display device 42 when a jackpot is won and a predetermined time after the jackpot game is over. As a result of the determination, if it is a big hit (S401: Yes), this processing is terminated as it is.

  If it is not during the big hit (S401: No), it is determined whether or not the large symbol display is being displayed by the large symbol display device 42 (S402), and if it is not during the large symbol variation display (S402: No), It is determined whether or not the number N of active suspension balls of the large symbol display device 42 is greater than 0 (S403). If the number N of active suspension balls is 0 (S403: No), this process is ended as it is. If the number of the operation holding balls N> 0 (S403: Yes), the operation holding ball number N is decremented by 1 (S404), and the data stored in the holding ball storage area is shifted (S405). 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. After the data shift processing, large symbol variation start processing is executed (S406). The variation start process will be described later with reference to FIG.

  In the process of S402, when the large symbol design is being displayed (S402: Yes), it is determined whether or not the variation time has elapsed (S407). The variation time of the large symbol is determined according to the variation pattern of the large symbol, and the execution of the process of S408 is skipped until the variation time elapses (S407: No). On the other hand, if the fluctuation time of the large symbol has elapsed (S407: Yes), a confirmation command set for the confirmation of the stop symbol is set (S408), and this process is terminated.

  Next, the variation start process will be described with reference to the flowchart of FIG. In the fluctuation start process (S406), first, it is determined whether or not a big hit is made based on the value of the big hit random number counter C1 stored in the execution area of the reserved ball storage area (S501). 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 the 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.

  When it is determined that the game is a big hit (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol is obtained based on a table (not shown) representing the corresponding relationship, and the symbol is set as a stop symbol command (S502). 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. Of these jackpot symbols, if they are arranged with a predetermined specific symbol (probability variation symbol), they will shift to the probability variation state. However, if they are arranged with a predetermined symbol (non-probability variation symbol), the probability change will occur. Does not transition to the state.

  Next, the variation pattern of the big game symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command (S503). 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) Etc., to determine a finer pattern variation mode. 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 the pattern or to set the 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 (S501: No), it is determined whether or not a reach has occurred based on the value of the reach random number counter C3 stored in the execution area of the reserved ball storage area ( If a reach has occurred (S504: Yes), it is also determined whether or not the front / rear reach has been reached based on the value of the reach random number counter C3 (S505). 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).

  When the front / rear outreach occurs (S505: Yes), the left, middle and right outreach symbol counters CL, CM, CR stored in the front / rear outreach symbol buffer of the RAM 503 are set as stop symbol commands ( S506). In addition, a fluctuation pattern for front / rear out of reach display is determined and the fluctuation pattern is set in a fluctuation pattern command (S507). At this time, similarly to the processing of 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.

  When a reach other than front / rear out is generated (S505: No), the values of 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. (S508). Further, a variation pattern for reach display other than front / rear deviation is determined, and the variation pattern is set in a variation pattern command (S509). 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 the process of S503.

  If neither big hit nor reach (S501: No, S504: No), the left, middle, and right outlier counters CL, CM, and CR stored in the RAM503 complete out symbol buffer are stopped. The symbol command is set (S510). Also, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command (S511). 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 the process of S503. As described above, when the setting of the stop symbol command and the variation pattern command is completed in any of the big hit, the reach occurrence, and the non-reach occurrence, this processing is ended.

  Next, payout control executed by the MPU 511 in the payout control device 311 will be described with reference to FIG. FIG. 44 is a flowchart showing a main process of the payout control apparatus 311. This main process is started by a reset at power-on.

  First, initial setting processing accompanying power-on is executed (S901). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Next, it waits for reception of the payout permission command transmitted from the main controller 261 (S902: No). When a payout permission command is received (S902: Yes), RAM access is permitted (S903), and an external interrupt vector is set (S904).

  Thereafter, a data backup process is executed for the RAM 513 in the MPU 511. Specifically, it is determined whether or not the RAM erase switch 323 provided in the power supply device 313 is pressed (S905). If it is turned on (S905: Yes), the backup data is cleared (erased). The process proceeds to S915. On the other hand, if the RAM erasure switch 323 is not turned on (S905: No), it is further determined whether or not the information on occurrence of power interruption is stored in the backup area 513a of the RAM 513 (S906). (S906: No), since the backup data is not stored, in this case as well, the process proceeds to S915. If the occurrence information of the power shutdown is stored in the backup area 513a (S906: Yes), the RAM judgment value is calculated (S907), and the calculated RAM judgment value is not normal (S908: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S915. As described above, the RAM determination value is a checksum value at a work area address of the RAM 513, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 513 is correctly stored.

  In the RAM initialization processing from S915, the used area of the RAM 513 is cleared to 0 (S915), and the initial value of the RAM 513 is set (S916). Thereafter, the MPU 511 peripheral device is initialized (S917), an interrupt is permitted (S918), 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 (S905: No), the occurrence information of the power shutdown has been set (S906: Yes), and the RAM judgment value (checksum value etc.) is normal ( S908: Yes), processing at power recovery (processing at power-off restoration) is executed. That is, the stack pointer at the time of power shutdown is restored (S909), and the information on occurrence of power shutdown is cleared (S910). Also, the MPU 511 peripheral device is initialized (S911), and the used registers are restored from the backup area 513a of the RAM 513 (S912). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S913). If the interrupt is permitted (S913: Yes), the interrupt is permitted (S914), while the interrupt is prohibited when the power is turned off. If it is in the state (S913: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, payout control processing will be described with reference to the flowchart of FIG. This payout control process is executed following the main process of the payout control device 311. In the payout control process, first, a command from the main control device 261 is acquired, and the total number of winning balls is stored (S1001). A launch permission is set for the launch controller 312 (S1002), and when the state return switch 321 is checked, if it is determined that the state return operation is started, the state return operation is executed (S1003).

  Thereafter, the setting of the lower plate full tank state or the lower plate full tank release state is executed according to the change in the state of the lower plate 15 (S1004). That is, when the lower plate 15 is full based on the detection signal of the lower plate full switch, when the lower plate is full, the setting of the lower plate full state is executed. , Set the lower pan full release state. Further, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change in the state of the tank ball (S1005). 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, the presence / absence of a notification state is determined, and if there is a notification state, notification is made by a 7-segment LED provided in the payout control device 311 (S1006).

  Next, prize ball payout processing is executed by each processing of S1007 to S1009. That is, if the prize ball is not paid out and the total number of prize balls stored in S1001 is not 0 (S1007: No, S1008: No), the prize ball control process shown in FIG. 46 is started (S1009). . On the other hand, if the prize ball cannot be paid out (S1007: Yes) or if the total number of prize balls is 0 (S1008: Yes), the process proceeds to the lending and payout process. The prize ball control process will be described later.

  In the rental ball payout processing of S1010 to S1012, if the ball payout is not possible and a ball ball payout request is received from the card unit (S1010: No, S1011: Yes), the ball rental shown in FIG. Control processing is started. On the other hand, if the rental ball cannot be dispensed (S1010: Yes) or if a rental ball dispensing request has not been received (S1011: No), the subsequent ball removal process is executed (S1013). The ball rental control process will be described later.

  In the ball removal process (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 is not disabled and the ball removal operation is not started. Subsequently, the control of the vibrator 360 (vibration motor control) is executed on the condition that the ball is clogged (S1014). Thereafter, the process returns to the top of the payout control process, and thereafter the above-described process is repeated.

  The prize ball control process shown in FIG. 46 will be described. In the winning ball control process, firstly, the payout motor 358a is driven to rotate in the forward direction to pay out the winning ball (S1101). Whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor (S1102). If not normal (S1102: No), the payout motor 358a is driven to execute a retry process and the payout motor 358a. The stop process is executed (S1103), and then the process returns to the payout control process of FIG.

  If the rotation of the payout motor 358a is normal (S1102: Yes), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (S1104). If the game ball count is not normal (S1104: No), the payout motor 358a is driven to execute the retry process and the payout motor 358a is stopped (S1105). Thereafter, the payout control process of FIG. 45 is executed. Return.

  Further, if the game ball count is normal (S1104: Yes), 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 is completed (S1106). If completed (S1106: Yes), a stop process of the payout motor 358a is executed (S1107), and then the process returns to the payout control process of FIG. On the other hand, if the payout has not been completed (S1106: No), the process returns to the payout control process of FIG.

  The lending control process shown in FIG. 47 will be described. In the ball lending control process, firstly, the payout motor 358a is driven to rotate in the reverse direction to execute lending of a lending ball (S1201).
