  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 is a perspective view showing a state in which a front frame set 14 and a lower tray unit 13 are opened with respect to an outer frame 11 and an inner frame 12 described later. However, in FIG. 2, for convenience, a game board 42 and a glass unit 150 described later are omitted.

  As shown in FIGS. 1 and 2, a pachinko machine 10 as a gaming machine includes an outer frame 11 that forms an outer shell of the pachinko machine 10, and an inner frame 12 is provided on one side of the outer frame 11. Is supported to be openable and closable. The outer frame 11 is mainly formed of a wooden plate material in a rectangular shape as a whole, and each plate material is assembled by a detachable fastener such as a small screw. Therefore, the structure can be easily reused as compared with the conventional structure in which the plates are assembled using nails and rivets. In this embodiment, the outer dimension of the outer frame 11 is 809 mm (inner dimension 771 mm), and the outer dimension in the left-right direction is 518 mm (inner dimension 480 mm).

  Further, as shown in FIGS. 3A and 3B, the outer frame 11 mainly supports the inner frame 12 and the like, so that an upper hinge 15, a lower hinge 16, and a pair of upper and lower claw horses 17 and 18 are supported. Etc. are installed. The claw horses 17 and 18 in the present embodiment are provided with so-called folded portions 17a and 18a by bending the tip portions thereof at substantially right angles. In the case where the inner frame 12 is closed due to the presence of the folded portions 17a and 18a, the saddle members 192 and 193 described later (see FIG. 23, etc.) without increasing the length of the claw horses 17 and 18 themselves. ) Can be more reliably stabilized.

  Further, a resin curtain decoration 19 is attached to the lower part of the outer frame 11 in the present embodiment. The traditional wooden curtain 19 is made of resin, which gives a sense of unity between the resin inner frame 12, the lower dish unit 13, and the front frame set 14, and improves the appearance quality. It has been. Although not shown in FIG. 3, a pattern is given to the front surface of the molded curtain decoration 19. In addition, metal sliding members 21 and 22 are provided on the upper surface of the curtain decoration 19, thereby ensuring smooth sliding when the inner frame 12 is opened and closed. In addition, a rib 23 protruding upward is integrally formed at the back of the upper surface of the curtain decoration 19. A return portion (not shown) that is bent at the front side is integrally formed at the upper end of the rib 23, thereby making it difficult to form a gap with the inner frame 12. It has been. The height of the rib 23 is set to a predetermined height that is at least equal to or less than the radius of a game ball as a game medium. Thus, even when a game ball is on the curtain decoration 19 when the inner frame 12 is closed, the game ball is driven backward by riding on the rib 23. That is, the situation (so-called “ball biting”) in which a game ball is sandwiched between the inner frame 12 and the rib 23 is prevented.

  1 and 2, the inner frame 12, the lower dish unit 13, and the front frame set 14 are made of synthetic resin, specifically ABS (acrylonitrile-butadiene-styrene) resin. By using a synthetic resin for molding each of these members, it is possible to cope with a more complicated shape as compared with the case of using a metal material, and it is also possible to suppress an increase in production cost. Advantages of using ABS include a low production cost, strong viscosity, and high impact resistance compared to resin materials such as polycarbonate. In addition, for example, when a coating process such as plating is performed on a design surface such as the front side of the front frame set 14, the process is relatively easy to perform, and there is an advantage that a product with higher appearance quality can be manufactured.

  The opening / closing axis of the inner frame 12 is set so as to extend vertically on the left side (opposite to the position where the handle 35 to be described later) is viewed from the front of the pachinko machine 10. 12 can be opened to the front side. More specifically, the upper and lower hinges 15 and 16 of the outer frame 11 support the upper and lower portions of the inner frame 12 so that the inner frame 12 can be opened and closed.

  In the present embodiment, not only the front frame set 14 but also the lower tray unit 13 is provided so as to be openable and closable on one side with respect to the inner frame 12. Conventionally, the lower dish unit is fixedly provided at the lower part of the inner frame. In this regard, in the present embodiment, the lower plate unit 13 is provided so as to be openable and closable, and the following effects are exhibited. First, the lower tray unit 13 is opened so that at least a part of the game ball launch unit and various parts can be accommodated. Secondly, various wirings can be accommodated, and it is easy to handle electrical connection with various electrical components. More specifically, a full sensor (for detecting that the lower plate 15 is full of game balls) is stored in the housing recess 24 provided at a position corresponding to the lower plate unit 13 below the inner frame 12. In addition, a part of a game ball launching unit 70 described later is accommodated. Further, a touch sensor in the handle 35, which will be described later, electrical wiring extending from the operation amount detection means, etc., a relay board DK, and the like are also accommodated. For example, the wiring extends from the handle 35 and is led out from the through hole 25 provided on one side of the housing recess 24 via the relay board DK, and is electrically connected to various control boards and the like. Yes. Note that due to the formation of the housing recess 24, there is a concern that the strength and rigidity of the inner frame 12 may be reduced, but in the present embodiment, it extends downward from the ball discharge portion 26. In addition, a rib (not shown) is provided, and the rib functions as a support part and a reinforcement part. As a result, the concern of a decrease in strength and rigidity is eliminated, and it also serves as a holder for electrical wiring.

  In addition, because of the fact that the lower plate unit 13 is supported on one side, there is a concern about the strength and rigidity of the lower plate unit 13 itself. In this respect, in the present embodiment, a reinforcing sheet metal 28 is attached to the surface (back surface) of the lower plate unit 13 on the inner frame 12 side on almost the entire surface.

  Further, a front frame set 14 is attached to the inner frame 12 so as to be openable and closable corresponding to a range excluding the lower plate unit 13 (above the lower plate unit 13). Both the lower pan unit 13 and the front frame set 14 can be opened to the front side with an open / close axis extending vertically to the left when viewed from the front of the pachinko machine 10, as in the case of the inner frame 12. FIG. 4 is a front view showing a state in which the front frame set 14 is removed from the pachinko machine 10 (however, in FIG. 4, the configuration in the game area on the surface of the game board 42 is shown as blank for convenience). Note that a rib R1 projects from the front side of the inner frame 12 at a periphery thereof (a portion corresponding to the front frame set 14). When the front frame set 14 is closed, the front frame set 14 is fitted into the rib R1. With this configuration, it becomes difficult to allow a wire or the like to enter from the gap between the front frame set 14 and the inner frame 12 and plays a role in preventing fraud.

  The lower tray unit 13 is provided with a lower tray 31 as a ball receiving tray at a substantially central portion, and game balls discharged from the discharge port of the ball discharge portion 26 are passed through a discharge port 30 formed in the lower plate unit 13. And can be stored in the lower plate 31. Most of the lower dish unit 13 is formed of ABS resin like the inner frame 12, but among these, the surface layer forming the lower dish 31 and the front panel 32 behind the lower dish are particularly flame retardant. Molded with ABS resin. For this reason, this part is difficult to burn. Reference numeral 33 denotes a sound output port from the speaker SP, and reference numeral 34 denotes a ball release lever for discharging the game ball from the lower plate 15 downward. In the present embodiment, the speaker SP is provided on the direct back side of the sound output port 33 (see FIG. 18 and the like).

  A game ball launching handle (hereinafter simply referred to as “handle”) 35 is disposed on the right side of the lower plate 31 so as to protrude to the front side. That is, the handle 35 is positioned on the right side when viewed from the front of the pachinko machine 10 on the side opposite to the opening / closing axis of the lower tray unit 13, and a predetermined opening amount when the inner frame 12 is opened regardless of the protrusion of the handle 35. Can be secured. An ashtray 36 is provided on the left side of the lower plate 31. The handle 35 includes a touch sensor (not shown) and an operation amount detection means (not shown) for detecting the operation amount of the operation unit of the handle 35 (the amount of operation can be detected by detecting a change in electrical resistance. Is provided).

  On the other hand, as shown in FIG. 1, an upper plate 37 serving as a ball tray is provided above the lower plate 31. Here, the upper tray 37 is a ball receiving tray for temporarily storing the game balls and guiding them to the game ball launching device while aligning them in a line. The upper plate 37 is configured integrally with the glass frame portion that supports the glass in the front frame set 14. In a conventional pachinko machine, a front decorative frame that can be opened and closed with respect to an inner frame below the glass frame is provided, and an upper plate is provided on the front decorative frame. Since the upper plate 37 is provided directly and integrally, even if the width of the frame portion of the front frame set 14 is relatively narrow compared to the conventional case as described later, the front frame set 14 (glass frame portion) ) Can be ensured. Similar to the lower plate 31, the upper plate 37 has a structure in which the surface layer is formed of flame-retardant ABS resin.

  In FIG. 4, the inner frame 12 is mainly composed of a resin base 40 having a rectangular outer shape, and a substantially circular window hole 41 is formed at the center of the resin base 40. A game board 42 is detachably mounted on the rear side of the resin base 40. The game board 42 is made of a rectangular plywood, and is attached in a state in which the peripheral edge thereof is in contact with the back side of the resin base 40 (inner frame 12). Accordingly, a substantially central portion of the front surface portion of the game board 42 is exposed to the front surface side of the inner frame 12 through the window hole 41 of the resin base 40. The game board 42 has a vertical length of 476 mm and a horizontal length of 452 mm (same size as before). The resin base 40 is provided with a not-shown opening detection sensor that detects opening of the front frame set 14. Although not shown, an open detection sensor for detecting the opening of the inner frame 12 is also provided.

  Next, the configuration of the game board 42 will be described with reference to FIG. The game board 42 has a general winning port 43 as a winning means, a variable winning device 44 as a winning means, a first opportunity corresponding port (starting opening) 45 as a winning means, and a second opportunity as a winning means. A corresponding port (through gate) 46, a variable display unit 47 and the like are disposed in a through hole formed by router processing, and are attached from the front side of the game board 42 with wood screws or the like. As is well known, a game ball enters the general winning port 43, the variable winning device 44, and the first opportunity corresponding port 45, and a predetermined number of prizes are given to the upper plate 37 (or the lower plate 31) by the output of a detection switch described later. The ball is paid out. In addition, the game board 42 is provided with an out port 48, and game balls that have not entered the various winning units (winning device, winning port, first opportunity corresponding port 45, etc.) pass through the out port 48. Then, it is guided toward a ball discharge path (not shown). A number of nails are planted on the game board 42 in order to disperse and adjust the falling direction of the game balls as appropriate, and various members (functions) such as a windmill 49 are arranged.

  The variable display device unit 47 includes identification information as a second symbol display device 51 that displays the second symbol in a variable manner triggered by the passage of the second opportunity correspondence port 46, and a winning in the first opportunity correspondence port 45. A first symbol display device 52 (special symbol display device) is provided as a symbol display device for variably displaying the first symbol (special symbol). The second symbol display device 51 (ordinary symbol display device) includes a display portion 53 for a second symbol (ordinary symbol) and a holding lamp 54, and each time a game ball passes through the second opportunity corresponding port 46, for example, When the display symbol (second symbol) by the display unit 53 fluctuates and the variation display stops at a predetermined symbol, the first opportunity corresponding port 45 is configured to be in an activated state (opened) for a predetermined time. . When a game ball newly passes through the second opportunity corresponding port 46 during the second symbol variation display on the display unit 53 of the second symbol display device 51, the corresponding second symbol variation display is It is configured to be performed after the end of the variable display performed at the time. That is, the variable display is on standby (held). The maximum number of the variable display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 44. Yes. However, the maximum number of holding times is not limited to this. For example, the maximum hold count may be set to 8 in order to wait for the second symbol variation display for 8 times. Note that the display unit 53 may be configured to be variably displayed on a part of the first symbol display device 52 (liquid crystal display device) in addition to the configuration to be variably displayed by switching the lighting of a plurality of lamps. . Similarly, the hold lamp 54 may be configured to be variably displayed on a part of the first symbol display device 52.

  The first symbol display device 52 is configured as a liquid crystal display device, and the display content is controlled by a display control device 55 described later. The first symbol display device 52 displays, for example, three symbol rows of left, middle and right. Each symbol row is composed of a plurality of symbols, and these symbols are variably displayed on the first symbol display device 52 so as to be scrolled for each symbol row. In the present embodiment, the first symbol display device 52 (liquid crystal display device) includes a large liquid crystal display of 8 inches. A center frame 57 is disposed in the variable display device unit 47 so as to surround the first symbol display device 52.

  The variable winning device 44 is normally in a closed state in which a game ball cannot be won or difficult to win, and in an open state in which a game ball is likely to win in the case of a big win (occurrence of a special game state) and a normal closed state It is designed to be operated repeatedly. More specifically, when a game ball wins the first opportunity corresponding port 45, the symbols are displayed in a variable manner on the first symbol display device 52, and the confirmed symbol after the stop is a combination of specific symbols set in advance. A special gaming state occurs as a necessary condition. The large winning opening of the variable winning device 44 is in a predetermined open state, and the game ball is configured to be in a state where it is easy to win (a big hit state). Specifically, the passage of a predetermined time or a predetermined number of winnings is defined as one round, and the big winning opening of the variable winning device 44 is repeatedly opened a predetermined number of times. When a new game ball wins the first opportunity corresponding port 45 during the symbol variation display of the first symbol display device 52, the symbol variation display for that time is the end of the symbol variation display being performed at that time. The configuration is performed later. That is, the symbol variation display is waited (held, stored) (storage means). The maximum number of symbol variation display to be held is determined for each model of the pachinko machine, but in this embodiment, it is held up to 4 times, and the hold number is lit and displayed by the hold lamp 56. ing. However, the maximum number of holding times is not limited to this. For example, the maximum number of holdings may be set to 8 in order to wait for 8 symbol fluctuation displays. Note that the hold lamp 56 may be configured to be variably displayed on a part of the first symbol display device 52.

  In addition, a guide rail for guiding the game ball launched from the game ball launch unit 70 to the upper part of the game board 42 is attached to the game board 42, and the game ball launched as the handle 35 is turned. Is guided to a predetermined game area through a guide rail. In the present embodiment, the rail includes an inner rail 58 and an outer rail 59 that are arranged in a double-spaced manner with a predetermined interval. Both rails 58 and 59 are made of a metal strip made of stainless steel. The inner rail 58 is formed in a substantially annular shape except for about 1/2 of the upper side and the right side. An outer rail 59 is provided so that a part (mainly the left side) faces the inner rail 58. In this case, a guide rail is mainly constituted by the inner rail 58 and the outer rail 59, and a ball guide passage is formed by a portion (the left portion facing) where the rails 58 and 59 are parallel to each other at a predetermined interval. Yes.

  A return ball preventing member 61 is attached to the tip of the inner rail 58 (the upper left portion in FIG. 5). This prevents a situation in which the game ball once guided from the ball guide path between the inner rail 58 and the outer rail 59 to the upper part of the game board 42 returns to the ball guide path again. Yes. Further, a resin arc member is provided between the end of the inner rail 58 opposite to the return ball preventing member 61 and the tip of the outer rail 59 (the right side). 62 is attached. A return rubber 63 is attached to the upper end portion (the portion on the outer rail 59 side) of the arc member 62, that is, the position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 5). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 63 and is returned to, for example, the substantially central portion side of the game board 42. Note that the lower right corner and the lower left corner of the game board 42 are spaces for attaching a seal such as a certificate or a plate (for example, S1 in the lower right corner of FIG. 5).

  Next, the game area will be described. The game area is partitioned and formed in a substantially circular shape by the inner periphery of the rail (inner and outer rails 58 and 59). In particular, in this embodiment, the game area partitioned on the board surface of the game board 42 is far more than conventional. It is greatly configured. In this embodiment, the distance from the uppermost point of the outer rail 59 to the lower part of the game board 42 is 445 mm (about 58 mm longer than the conventional product), from the extreme left position of the outer rail 59 to the extreme right position on the inner surface of the arc member 62. The distance between is 435 mm (about 50 mm longer than the conventional product). The distance from the extreme left position of the inner rail 58 to the extreme right position of the inner surface of the arc member 62 is 418 mm.

  In the present embodiment, the game area is an area of a guide rail that is a parallel part of the inner and outer rails 58 and 59 among the areas surrounded by the inner rail 58, the outer rail 59, and the arc member 62 when viewed from the front of the pachinko machine 10. The area is excluded. 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 59 but by the inner rail 58. Similarly, the right limit position toward the game area is specified by the arc member 62. The lower limit position of the game area is specified by the lower end position of the game board 42. The upper limit position of the game area is specified by the outer rail 59.

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

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

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 42 is about 70%, which is a much larger area ratio than before. The area ratio of the game area to the surface of the game board 42 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 42 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 42 must be the same, the surface of the game board 42 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.

  Note that the second opportunity corresponding ports 46 located on both sides of the variable display device unit 47 have a guide mechanism that allows the game balls that have passed through the second opportunity corresponding port 46 to be moved toward the center. Thereby, even when the game area is expanded in the left-right direction, the game ball can be guided toward the first first opportunity corresponding port 45 and the variable prize-winning device 44. By expanding, it is possible to suppress a decrease in interest due to difficulty in winning a game ball. Furthermore, by extending the game area in the left-right direction, the second opportunity corresponding port 46, the windmill 49, a plurality of nails (guide nails for guiding the game ball to the center), and various other objects are arranged. The behavior of the game ball in the game areas on the left and right sides of the variable display unit 47 can be made more interesting. In addition, since the gaming area is also expanded in the vertical direction, the second opportunity corresponding port 46, the windmill 49, a plurality of nails, and other accessories can be arranged in various ways. The behavior of the game ball can be made even more interesting.

  Returning to the description of FIG. 4, in the resin base 40, a game ball launch unit 70 is attached below the window hole 41 (game board 42). 6 is a front view of the game ball launching unit 70, FIG. 7 is a perspective view thereof, FIG. 8 is a perspective view showing a state in which an opening / closing portion 82, which will be described later, is opened, and FIG. FIG. 10 is an exploded perspective view of the game ball launching unit 70. More specifically, the game ball launch unit 70 includes a metal base plate 71 fixed to the resin base 40, a launch device 72 attached to the base plate 71, and a tip of the launch device 72. On the side, a launching rail 73 having a substantially M-shaped cross section attached to the base plate 71 so as to extend parallel to the longitudinal direction of the launching device 72, and guiding the game balls one by one to the base end of the firing rail 73 A ball feed mechanism 74 attached to the base plate 71 for guiding, and a base plate 71 for supporting and positioning a game ball placed on the base end portion (right end portion in the figure) of the firing rail 73. Positioning member 75 (see FIGS. 8 and 9).

  The launch rail 73 is for guiding the game ball immediately after being launched from the launch device 72, and extends linearly so as to have a predetermined launch angle (launch angle). Then, the game ball launched in accordance with the turning operation of the handle 35 is first launched obliquely upward along the launch rail 73 and then guided to a predetermined game area through the ball guide passages of the rails 58 and 59 as described above. It has become so.

  In the case of this pachinko machine 10, it has already been described that the game area is greatly expanded compared to the conventional case, but under such a configuration, the curvature of the guide rail must be reduced, so that the launch ball is stabilized. Need some ingenuity. Therefore, in the present embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 73 is made somewhat larger than the existing one (that is, the launch rail 73 is raised), and the launch rail is further increased. The length of 73 is made longer than the existing one so as to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the game ball launching device can be guided to the rails 58 and 59 in a more stable state. In this case, in particular, the launch rail 73 is formed so as to extend from the launch position by the launch device 72 to a position beyond the center position (out port 48) in the left-right direction of the game area. In addition, since the launch rail 73 is configured as described above, in this embodiment, the base plate 71 is also relatively larger than the conventional one, and the number of fixing means (screws) for fixing the base plate 71 is increased compared to the conventional one. .

  In the present embodiment, a linear solenoid is employed as the launching device 72 instead of a combination of a motor and launching rod that are generally employed conventionally. That is, the launching device 72 includes a plunger 76 extending in parallel with the firing rail 73, and a hitting portion 77 for hitting a game ball is attached to the tip of the plunger 76. In this embodiment, a polyester-based thermoplastic elastomer is employed as a material constituting the hitting portion 77. Under such a configuration, the launch device 72 is repeatedly excited and de-energized every predetermined time, whereby the plunger 76 is repeatedly raised and retracted. Each time the plunger 76 protrudes, the game ball positioned at a predetermined position is launched from the launch rail 73. Note that the protruding speed of the plunger 76 is appropriately adjusted based on the operation amount of the handle 35 (the stroke amount is substantially constant), thereby adjusting the firing speed of the game ball and hence the flying amount. The firing device 72 is fixed with screws to four bosses erected on the base plate 71. In the present embodiment, the lower two bosses are fixed to the base plate 71. On the other hand, the upper two bosses can be adjusted in height (projection amount). Therefore, by appropriately adjusting the protrusion amount of the boss, the height (protrusion amount) to which the launching device 72 is attached, and consequently the tip position of the plunger 76, that is, the hitting point of the game ball can be adjusted. Yes.

  The positioning member 75 is for supporting and positioning a game ball placed on the base end portion of the firing rail 73, and has a substantially cylindrical shape. The positioning member 75 is formed with a screw hole penetrating in the vertical direction, and a screw hole is also formed at a predetermined position of the base plate 71. And the positioning member 75 is attached by screwing a screw in the state in which both screw holes are aligned. In the present embodiment, the screw hole on the positioning member 75 side is formed not at the center position but at a slightly eccentric position. Therefore, the distance between the side surface of the positioning member 75 and the base end portion of the firing rail 73 can be slightly changed by screwing the screw after the positioning member 75 is appropriately rotated. That is, by rotating the positioning member 75, the support position of the game ball, and thus the stop position immediately before the game ball can be released can be finely adjusted.

  The ball feeding mechanism 74 is for guiding the game balls guided from the upper plate 37 side one by one to the base end portion of the firing rail 73. The ball feed mechanism 74 can be opened and closed at a resin pedestal portion 81 fixed to the base plate 71 so as to cover the upper portion of the launching device 72 and one side (right side in the figure) of the pedestal portion 81. It is also provided with a resin-made opening / closing part 82 that is pivotally supported. A locking claw 83 projecting forward is integrally formed on the pedestal portion 81, and a locking hole 84 is formed on the opposite side of the opening / closing portion 82 from the support shaft. The opening / closing part 82 is always closed. That is, when the opening / closing part 82 is closed, the locking claw 83 is inevitably locked in the locking hole 84, and thus the closed state is maintained.

  An introduction port 85 for introducing a game ball guided from the upper plate 37 is provided at the front portion of the opening / closing unit 82, and the game ball is introduced downward from the introduction port 85. A lid 82a is detachably attached to the rear part of the opening / closing part 82, and an electromagnet 86 and a sending piece 87 for sending out game balls one by one are provided in the internal space of the opening / closing part 82. ing. The sending piece 87 has a corner portion (a shaft support portion 87a) at one end thereof rotatably supported with respect to the opening / closing portion 82, and can accommodate only one game ball on the opposite side to the shaft support portion 87a. The holder portion 88 is provided in a recessed manner. A metal piece 89 made of magnetic metal is attached to the upper side portion connecting the holder portion 88 and the shaft support portion 87a so as to face the electromagnet 86. With this configuration, when the electromagnet 86 is turned on, the metal piece 89 is pulled so as to stick to the electromagnet 86 and the delivery piece 87 rotates upward. Thereby, the game ball introduced from the introduction port 85 is accommodated in the holder part 88, and the downward flow of the game ball is restricted. On the other hand, when the electromagnet 86 is turned off, the delivery piece 87 rotates downward due to gravity, and the game ball accommodated in the holder portion 88 flows downward, so that the base of the launch rail 73 is reduced. Guided to the end. In addition, when the electromagnet 86 is turned off, the flow of the next game ball to the holder portion 88 is restricted by the upper portion of the delivery piece 87. Therefore, the on / off operation of the electromagnet 86 is repeatedly executed, whereby the game balls are guided to the firing start position (predetermined position) one by one. In addition, it is comprised so that on / off of the electromagnet 86 and excitation / non-excitation of the launcher 72 (solenoid) may be synchronized.

  Returning to the description of FIG. 4, there is a predetermined gap between the firing rail 73 and the rails 58 and 59 (guide rail), and a foul ball passage 91 is formed below the gap. Therefore, if the game ball fired from the launching device 72 does not reach the return ball prevention member 61 and returns to the inside of the guide rail as a foul ball, the foul ball passes to the lower plate 31 via the foul ball passage 91. Discharged. Incidentally, in the case of the present embodiment, the length of the firing rail 73 is about 170 mm, and the length of the gap on the distal end side of the firing rail 73 (the length on the extension line of the firing rail 73) is about 68 mm.

  In FIG. 4, reference numeral 92 denotes a discharge port that communicates with the upper plate 37, and the game ball is discharged to the upper plate 37 through the discharge port 92. An open / close shutter 93 is attached to the discharge port 92. Although detailed disclosure of the drawings is omitted, the shutter 93 can be rotated about the shaft portion provided along the lower side portion thereof, and the front frame set 14 is opened (state shown in FIG. 4). The shutter 93 substantially closes the discharge port 92 by a biasing force such as a spring. When the front frame set 14 is closed, the shutter 93 is pushed open by a ball passage rod 94 (see FIG. 2) provided on the back surface of the front frame set 14. Note that the game ball is discharged to the lower plate 31 in the open state of the front frame set 14. Therefore, as described above, in the pachinko machine 10 configured such that the upper plate 37 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. Can be prevented.

  The resin base 40 is provided with small rectangular windows 95 and 96 at the lower left and right sides of the window hole 41. Accordingly, a seal or the like (for example, S1 in FIG. 5) stretched at the left and right lower corners of the game board 42 can be visually recognized through the small windows 95 and 96. It is also possible to affix the above-mentioned seal or the like from the small windows 95 and 96.

  Further, the resin base 40 is provided with a substantially oval small window 97 at the upper left of the window hole 41, and a substantially oval hole 98 (see FIG. 5) in the upper left part of the game board 42 corresponding to the small window 97. Reference) is provided. Various electrical wirings (not shown) connected to an arcuate illumination part 112 of the front frame set 14 to be described later are led from the back side of the pachinko machine 10 through the small window 97 and the hole 98.

  Also, support metal fittings 101, 102, and 103 are attached to the left end of the inner frame 12 in FIG. 4 as a support mechanism for the front frame set 14 and the lower dish unit 13. The upper support bracket 101 is provided with a support hole 104 having a notch on the front side of the figure, and the middle support bracket 102 is provided with projecting shafts 105 and 106 protruding in the vertical direction, respectively. Further, the lower support fitting 103 is provided with a support hole (not shown).

  Next, the front frame set 14 will be described with reference to FIGS. FIG. 11 is a rear view of the front frame set 14. The front frame set 14 is formed with a substantially elliptical window 111 so that most of the game area can be visually recognized from the outside. Specifically, the window portion 111 has a shape in which a substantially central portion on the left and right sides is curved relatively gently as compared with the upper and lower sides. The substantially central portion may be linear. In the present embodiment, the distance between the upper end of the window portion 111 (the uppermost portion of the outer rail 59, the upper end of the game area) and the upper end of the front frame set 14 (the so-called vertical width of the upper frame portion) is about 50 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-sized variable display device unit 47 can be arranged relatively upward. The distance between the upper end of the front frame set 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

  Also, the shortest distance between the left end of the window 111 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. 11), 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 is apparent from a comparison between FIGS. 1 and 4, in the state where the front frame set 14 is closed, a part of the left end portion of the outer rail 59 is covered by the left frame portion. 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 59 and the left end position of the outer frame 11 when viewed from the front of the pachinko machine 10 is about 30 mm, the right end position of the game area (the right end position of the arc member 62) and the outer frame 11 The distance in the left-right direction from the right end position is about 44 mm.

  In addition, the front frame set 14 is provided with light emitting means such as various lamps around it (for example, a corner portion). These light emitting means play a role of enhancing the effect of the game during the game by changing and controlling the light emission mode such as lighting and blinking according to the change of the game state at the time of big hit or predetermined reach. For example, an arcuate illumination part 112 containing a large number of light emitting means such as LEDs is provided on the periphery of the window part 111. In the present pachinko machine 10, the arcuate lighting part 112 functions as an effect lamp such as a jackpot lamp, and is turned on or flashing at the time of jackpot or reach effect, etc. Inform the effect. In addition, on the left and right sides of the arcuate illumination part 112, there are provided a prize ball lamp 113 that is lit during the payout of a prize ball and an error display lamp 114 that is lit when a predetermined error occurs. Further, a small window 115 to which a transparent resin is attached is provided so as to be close to the lower end portion of the arcuate electric decoration portion 112 so that the inside can be visually recognized. In the present embodiment, chrome plating is applied in many regions on the surface side of the arcuate illumination part 112 in order to bring out more glamor. At the time of chromium plating in the present embodiment, trivalent chromium is used in consideration of the production environment and the like, instead of hexavalent chromium which has been widely used conventionally.

  In addition, a ball lending operation unit 120 is disposed below the window 111, and the ball lending operation unit 120 is provided with a ball lending button 121, a return button 122, and a frequency display unit 123. If the ball lending operation unit 120 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) arranged on the side of the pachinko machine 10, a game ball is lent according to the operation. . The ball lending button 121 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is supplied to the upper plate 37 as long as there is a remaining amount on the card or the like. Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine is achieved.

  As shown in FIG. 11, a light emitting substrate 124 for the light emitting means is attached to the upper corner portion on the back side of the front frame set 14. Further, 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 111. 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 111, respectively. The reinforcing plates 131 to 134 are connected in contact with each other, but the light emitting substrate 124 is covered so as to avoid direct contact between the light emitting substrate 124 and the reinforcing plate 131. Alternatively, a resin part 135 for preventing energization of the light emitting substrate 124 is provided. As a result, generation of noise and magnetic field in the light emitting substrate 124 is suppressed. The reinforcing plates 131 to 134 are grounded by a grounding mechanism (not shown).

  The right reinforcing plate 131 in FIG. 11 is provided with an engaging claw 131a having a hook shape at an intermediate position thereof. It is configured to be engaged with 12a (see FIG. 4 and the like). With this configuration, the front frame set 14 is configured to include the upper plate 37, and even if the upper and lower pivot support positions are extended, the front frame set 14 can be prevented from being lifted at the intermediate position. Therefore, an illegal act or the like floating the front frame set 14 is suppressed.

  Further, a pair of upper and lower front frame set flanges 14a and 14b extending to the back side of the front frame set 14 are integrally formed on the left reinforcing plate 131 in FIG.

  Furthermore, although it has been described above that chrome plating is applied in many regions on the surface side of the arcuately decorated portion 112, if the area of the plated portion is large, it tends to be easily charged accordingly. In this respect, in the present embodiment, a portion of the arcuately illuminated portion 112 that has been plated with chrome and the upper reinforcing plate 133 in FIG. Has been. As a result, it is possible to suppress problems such as charging due to frequent use of plating and noise caused by the plating.

  In addition, a resin-made rail side wall member 136 is provided on the lower reinforcing plate 134 at a position facing the firing rail 73 (see FIG. 4). The rail side wall member 136 becomes the side wall of the firing rail 73 when the front frame set 14 is closed. Therefore, the game ball is prevented from spilling from the launch rail 73.

  In addition, a ball outlet 141 is provided in the vicinity of the rail side wall member 136 so that the most downstream portion of the upper plate 37 communicates with the introduction port 85 of the game ball launch unit 70 when the front frame set 14 is closed. ing. An opening / closing member 142 is attached to the lower reinforcing plate 134 so that the ball outlet 141 can be opened and closed. As shown in FIG. 12 and the like, the opening / closing member 142 includes a housing 143 attached to the lower reinforcing plate 134 above the ball outlet 141, and an upper end accommodated in the housing 143. The portion extends downward so as to substantially follow the lower reinforcing plate 134, and is connected to the tongue piece 144 having flexibility and spring elasticity, and the tongue piece 144 within the housing 143. On the inner frame 12 side (the back side when the front frame set 14 is closed), an upper end is pivotally supported, and a rear portion includes a hard resin pressed portion 145 extending downward. When the front frame set 14 is in the open state, the pressed portion 145 has its tip side (lower end side) somewhat protruding toward the back, and the lower end of the tongue piece portion 144 is the sphere. It hangs down to a position where the upper part of the outlet 141 is blocked. That is, in this case, the flow of the game ball on the upper plate 37 is restricted by the tongue piece portion 144 and is not guided from the ball outlet 141 to the introduction port 85 side. On the other hand, when the front frame set 14 is closed, the pressed portion 145 hits and is pressed against the tip of the protrusion 146 extending forward from the inner frame 12. Then, the tongue piece 144 connected thereto is pulled upward and is slid. By this sliding, the ball outlet 141 is opened, and the game balls on the upper plate 37 are sequentially guided from the ball outlet 141 to the introduction port 85.

Furthermore, in this embodiment, the glass unit 150 including a pair of front and rear glass plates is attached on the back side of the front frame set 14. The glass unit 150 in the present embodiment is not attached to a pair of front and rear rectangular glass plates in front and back, but is attached as a whole in a round shape and assembled. It has been.
Here, the detail of the glass unit 150 and its attachment structure are demonstrated.

  FIG. 13 is a front view showing the glass unit 150, and FIG. 14 is a partially enlarged sectional view showing the glass unit 150. FIG. 15A is an enlarged cross-sectional view illustrating an example of the attachment portion, and FIG. 15B is a diagram schematically illustrating an example of the attachment portion. FIG. 16 is an enlarged cross-sectional view showing a part of the dew condensation prevention film and the like.

  As shown in these drawings, the glass unit 150 substantially corresponds to the shape of the window portion 111 and is provided so as to surround a pair of front and rear plate glasses 151 and 152 having a substantially circular shape and the periphery of the plate glasses 151 and 152. The holding frame 153 is provided. The holding frame 153 in the present embodiment is made of ABS resin. The holding frame 153 includes a holding portion main body 154 having a substantially “H” -shaped cross section, and mounting portions 155 that protrude outward from the holding portion main body 154 at a plurality of locations.

  Since the holding section main body 154 has the above-described cross-sectional shape, a pair of hook-shaped holding sections is formed (however, a portion corresponding to the mounting section 155 is partially cut away). And the said plate glass 151,152 is adhere | attached with this holding | maintenance part at predetermined intervals (it adhere | attaches with a hot-melt-adhesive etc.) and is fixed. In addition, the holding | maintenance part main body 154 is equipped with the upper and lower conductive parts 154a in order to make it electrically conductive to the conductive layer 159b of the dew condensation prevention films 151a and 152a described below.

  That is, on the opposing surfaces of the pair of glass plates 151 and 152, anti-condensation films 151a and 152a as film-like dew condensation preventing means are attached in advance to prevent condensation and fogging on the glass plates 151 and 152. ing. More specifically, after the transparent adhesives 151b and 152b are applied to the surfaces of the plate glasses 151 and 152, the dew condensation preventing films 151a and 152a are attached.

  The dew condensation preventing films 151a and 152a have an area that can cover the entire game area and have transparency. Therefore, even if the films 151a and 152a are attached to the plate glasses 151 and 152, the visibility of the game area is not hindered.

  Further, as shown in FIG. 16, the anti-condensation films 151a and 152a include a base material 159a, a conductive layer 159b located on the base material 159a, an insulating layer 159c located on the conductive layer 159b, A hydrophilic layer 159d located on the insulating layer 159c. The conductive layer 159b generates heat by being conducted to heat the hydrophilic layer 159d and the like, and is made of, for example, a composite oxide film of indium and tin. That is, in this embodiment, the conductive layer 159b constitutes a heating unit that heats the plate glasses 151 and 152.

  The hydrophilic layer 159d is made of polyethylene, polyvinyl alcohol, polyacrylic acid, or the like, and has a function of absorbing attached water droplets into the layer and a function of reducing the contact angle of the water droplets. Thereby, clouding and dew condensation can be prevented. The insulating layer 159c has a function of preventing the conductive layer 159b from coming into contact with moisture of the hydrophilic layer 159d and preventing a change in resistance value and ionization of the conductive layer 159b. However, the hydrophilic layer 159d on the insulating layer 159c is omitted at both ends on the outer peripheral side of the dew condensation preventing films 151a and 152a, and the conductive layer 159b is exposed (the left end in FIG. 16). Only the part is shown). The exposed conductive layer 159b is configured to be directly conductive through the conductive portion 154a of the holding portion main body 154.

  Specifically, as shown in FIGS. 14 and 16, the conductive portion 154 a includes an outer connection terminal 154 b disposed on the outside of the holding portion main body 154 and an electricity disposed on the inner side of the holding portion main body 154. In order to electrically connect with the connection part 154c, it is comprised so that the inside of the holding | maintenance part main body 154 may be penetrated. Then, the electrical connection portion 154c is brought into contact with the conductive layer 159b, whereby the electrical connection portion 154c is electrically connected to the conductive layer 159b.

  The electrical connection portion 154c is extended by a predetermined length along the outer peripheral direction of the glass plates 151 and 152 (the front side and the depth direction in FIG. 16). Therefore, between the electrical connecting portion 154c having a predetermined length located at the left end shown in FIG. 16 and the electrical connecting portion 154c having a predetermined length located at the opposite right end through the conductive layer 159b. Conduction is possible.

In addition, electrical wiring (not shown) is connected to the connection terminals 154b on both sides of the outer periphery, and a voltage is applied to the connection terminal 154b via the electrical wiring. As a result, when a current flows through the conductive layer 159b through the conductive portion 154a, the conductive layer 159b generates heat. The conductive layer 159b described above is provided on the entire surface of the plate glasses 151 and 152. However, for example, the conductive portion may be changed to a linear heating pattern L1 shown in FIG. The linear heat generation pattern L1 is shaped so as to follow the shape of the first symbol display device (liquid crystal display device) 52 as much as possible. Thereby, even if the heat generation pattern L1 is made of metal and is not transparent, the player is less likely to be annoying, and the aesthetic appearance of the pachinko machine 10 is not impaired.

At the time of bonding and fixing, first, the holding body 154 is bonded and fixed in a state where one plate glass 151 or 152 is placed. Next, the other plate glass 152 or 151 is bonded and fixed. At this time, the other plate glass 152 or 151 is pushed with a relatively strong force in order to make the bonding more reliable. During the pressing, the air between the pair of glass plates 151 and 152 may be compressed. If the air is compressed, there is a concern that the other glass plate 152 or 151 may be peeled off due to the expansion force. In this respect, in this embodiment, the escape hole 158 is opened along with the pressing. To the outside. In other words, air can enter and exit through the escape hole 158. Therefore, a situation in which the other plate glass 152 or 151 is peeled off does not occur. Then, after the bonding of the other plate glass 152 or 151 is completed, an adhesive is injected into the escape hole 158 and dried and hardened when the air between the plate glasses 151 and 152 becomes normal pressure. Thereby, intrusion of moisture and the like from the outside can be regulated while maintaining the normal pressure state between the plate glasses 151 and 152, and the air existing between the pair of plate glasses 151 and 152 is sealed or almost sealed. It becomes a state. The air in the space is dehumidified by the dew condensation prevention films 151a and 152a, so that the occurrence of dew condensation is prevented.

  A back frame set 215 is attached to the back surface of the game board 42 so as to surround the variable display device unit 47. 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 42, 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 game board opening of the aforementioned general winning port 43, variable winning device 44, first opportunity corresponding port 45 (see FIG. 5 respectively) and 1 on the downstream side. A collection passage 216 that collects at a place is formed. Also, below the game board 42, a discharge passage board 217 made of resin (for example, made of polycarbonate resin) is also attached to the inner frame 12, and the discharge ball is put out of the pachinko machine 10 to the discharge passage board 217. A discharge passage 218 for guiding is formed. Therefore, as illustrated in phantom lines in FIG. 28, all the game balls won in the general winning opening 31 and the like gather through the collection passage 216 of the back frame set 215, and further, the discharge passage 218 of the discharge passage board 217. Through the pachinko machine 10. In addition, the out port 48 (see FIG. 5) similarly leads to the discharge passage 218, and the game balls that have not won any winning opening are discharged to the outside of the pachinko machine 10 through the discharge passage 218.

Conventionally, since the portion corresponding to the game ball distribution unit 245 is provided on the back pack unit 203 side, the back pack unit 203 is pushed through the ball discharge port (ball passage rod 94 in FIG. 2) reaching the upper plate 37. As a result, a gap is formed between the inner frame 12 and a portion corresponding to the game ball distributing unit 245, and an illegal act of inserting a wire or the like through the gap and operating the internal device has been considered. Therefore, in the pachinko machine 10, such illegal acts are prevented by providing the game ball distribution unit 245 on the inner frame 12 side and fixing the game ball distribution unit 245 by a fixing means. Further, the upper end surface of the game ball distributing unit 245 is formed in accordance with the height position where the lower end surface of the game board 42 is installed, and is devised so as not to prevent the removal of the game board 42.

  Next, the first control board unit 201 will be described with reference to FIGS. 31 is a front view of the first control board unit 201, FIG. 32 is a perspective view of the unit 201, FIG. 33 is an exploded perspective view of the unit 201, and FIG. 34 is an exploded perspective view of the unit 201 viewed from the back. .

  The first control board unit 201 has a mounting base 251 having a substantially L shape, and a main control device 261 and an audio lamp control device 262 as control devices are mounted on the mounting base 251. Here, the main control device 261 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that stores necessary data according to the progress of the game, a port that communicates with various devices, and various lotteries. It has a main board including a random number generator used, a clock pulse generation circuit used for time counting and synchronization, and the main board is accommodated in a board box 263 made of a transparent resin material or the like. It is configured. 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 the sealing unit 264 as the sealing means, any configuration can be applied as long as it connects the box base and the box cover so that they cannot be opened. Here, as shown in FIG. 31 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 board box 263 is left in the board box 263, it can be easily found that the illegal opening has been performed by looking at the board box 263.

  However, the main board is provided with terminal portions for connecting the connectors of the cable connectors, and the terminal portions are exposed from the board box 263. The exposure of the terminal portion is the same for other substrates and substrate boxes.

  The voice lamp control device 262 is a voice lamp including a CPU that controls voice and lamp display in accordance with instructions from the main control device 261 (main board) or the display control device 55, and other ROM, RAM, various ports, and the like.

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.

  The main control device 261 (main substrate) is arranged in a landscape orientation on one substrate mounting surface 252 and the audio lamp control device 262 (audio lamp control substrate) is arranged in a portrait orientation on the other substrate mounting surface 253. It is arranged in the direction. 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. 32 and the like, the main controller 261 is arranged in a state in which a part thereof (about 1/3 in this embodiment) is floated. Therefore, the sound lamp control device 262 can be expanded to an area overlapping with the main control device 261, and the enlargement of the control board can be dealt with satisfactorily. Also, each control device can be installed efficiently. In addition, when the first control board unit 201 is mounted on the game board 42, a space is secured behind the board mounting surface 252, and the variable winning device 44 and its electric wiring can be installed without difficulty.

  As shown in FIGS. 33 and 34, the board mounting surface 252 for the main board has 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 positions on the left and right sides of the back surface. 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 in a state where it floats 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 face in FIG. 31 and the like, and by attaching the support shafts 256 to the support fitting 231 shown in FIG.

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 jam in the payout motor unit, the payout motor is rotated forward and reverse so that the ball jam is eliminated (return to the normal state). It has become.

  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 holding down the RAM erase switch 323. We are going to throw it in.

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

Further, in the present embodiment, a rotating I-type fastener is employed as the locking portion M8 in the vicinity of the tank 355 that stores a lot of game balls and is relatively loaded. For this reason, the back pack unit 203 (tank 355) can be more reliably locked as compared with the case where a fixture such as a ny latch is used. At this time, the back pack unit 203 is also fixed to the inner frame 12 by the fixtures 241 and 243 shown in FIG. The support hole portion 238 and the support shaft 385 are in the support shaft portion M6 of FIG. Equivalent to. Further, the fixture 243 corresponds to the locking portion M9 (see FIG. 27).

  The power failure monitoring circuit 542 is a circuit for outputting a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of the power failure and execute the power failure processing (NMI interrupt processing in FIG. 51).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

The

  Although not shown, the first symbol display device (liquid crystal display device) 52 has three symbol rows of left, middle and right, and the symbol (first symbol) varies for each symbol row. Is displayed. In the present embodiment, for example, the first symbol is configured so as to be given numbers “0” to “9”, respectively, and the first symbol is displayed in ascending or descending order of numbers to form a series of symbol strings. Yes. And the 1st symbol is variably displayed from top to bottom with periodicity.

  In this case, in the left symbol row, the first symbol is displayed in descending order (in the order in which the attached numbers decrease), and in the middle symbol row and the right symbol row, the first symbol is also in ascending order (the appended numbers are the same). (In increasing order). 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, the first symbol is a combination of jackpot symbols on the first symbol display device 42 (in this embodiment, the same first A special game video is displayed as a jackpot if the symbols are combined (a combination of symbols) (a jackpot state is started).

  In addition, the electricity generated by the power generation device 220c is input to the control unit 220g and is then conducted to the conductive portion 159b of the dew condensation prevention films 151a and 152a. The control unit 220g includes a power storage unit (not shown) such as a capacitor, and is configured to apply a predetermined voltage to the conductive unit 159b.

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

  In the present embodiment, the CPU 501 in the main control device 261 performs lottery (big hit lottery) of the first symbol display device 52 and symbol display setting using various counter information in the game. Specifically, 43, the jackpot random number counter C1 used for the jackpot lottery of the first symbol display device 52, the jackpot symbol counter C2 used for the selection of the jackpot symbol of the first symbol display device 52, and the first symbol Reach random number counter C3 used for reach lottery when the display device 52 fluctuates and changes, random number initial value counter CINI used for initial value setting of the big hit random number counter C1, and used for variation pattern selection of the first symbol display device 52 Variation type counters CS1 and CS2 to be used, and left, middle and right outlier symbols used for setting the outlier symbols in the left, middle and right columns Printer CL, CM, has decided to use a CR.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is periodically updated, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. In addition, the RAM 503 is provided with a holding ball storage area as a storage area composed of one execution area and four holding areas (holding first to fourth holding areas). The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in time series in accordance with the winning histories of the game balls to the one opportunity corresponding port 45.

  In detail, each of the counters is configured such that the jackpot random number counter C1 is incremented one by one within a range of, for example, 0 to 676, and returns to 0 after reaching the maximum value (that is, 676). In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding port 45. There are two types of random number values that are jackpots, low probability and high probability. In this embodiment, the number of random numbers that are jackpots at low probability is 2, and the value is “ 337, 673 ", and the number of random numbers that are jackpots at high probability is 10, and the values are" 67, 131, 199, 269, 337, 401, 463, 523, 601, 661 ". The high probability means a state where the jackpot is won by a predetermined probability variation pattern and the subsequent jackpot probability is increased as added value, that is, a so-called probable state, and the normal time (low probability) is When not in a certain state.

  The jackpot symbol counter C2 determines a symbol when the first symbol display device 52 stops changing in the case of a jackpot. In the present embodiment, the first symbol display device 52 has ten patterns of the first symbol set. Therefore, 10 (0 to 9) counter values are prepared. In other words, the jackpot symbol counter C2 is configured so that 1 is added in order within the range of 0 to 9, and after reaching the maximum value (that is, 9), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding port 45.

  Further, the reach random number counter C3 is configured to increment one by one within a range of 0 to 238, for example, and returns to 0 after reaching the maximum value (that is, 238). In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting by one by one before and after the reach symbol. “Reach other than front / rear off” that stops other than front and back and “complete out” that does not occur reach are selected by lottery. For example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 is front / back It corresponds to reach other than detachment, and C3 = 22 to 238 corresponds to complete detachment. The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 52, the number of starting and holding balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment) and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the first opportunity corresponding port 45.

  Further, one of the two variation type counters CS1 and CS2 is incremented by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. For example, the other variation type counter CS2 is incremented one by one within a range of 0 to 240, for example, and reaches the maximum value (that is, 240) and then returns to 0. In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”. The first variation type counter CS1 determines the reach type of the first symbol, such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes. The second variation type counter CS2 determines the final stop symbol ( In this embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol.

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

  The left, middle, and right out symbol counters CL, CM, CR are displayed in the left column, the first symbol, the middle column, the first symbol, and the right column, the first symbol, when the first symbol display device 52 loses the jackpot lottery. This is for determining the stop symbol (disconnected symbol), and since each of the ten first symbols is displayed in each column, ten counter values (0 to 9) are prepared for each symbol. . The stop symbol of the left symbol row is determined by the off symbol counter CL, the stop symbol of the middle symbol row is determined by the off symbol counter CM, and the stop symbol of the right symbol row is determined by the off symbol counter CR.

  In the present embodiment, the value of each counter CL, CM, CR is updated at random by using the value of the R register built in the CPU 501. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, 10 is subtracted to determine the current value. The Each outlier symbol counter CL, CM, CR is updated within the normal processing so that the update times do not overlap, and the combination of these outlier symbol counters CL, CM, CR is the reach of the RAM 503 front / rear out symbol buffer, reach other than front / rear out It is stored in either the symbol buffer or the completely off symbol buffer. Then, when determining the variation pattern at the start of variation of the first symbol, the buffer value of any one of the front and rear outreach symbol buffer, the reach symbol buffer other than front and rear outlier and the completely out symbol symbol buffer is acquired according to the value of the reach random number counter C3. The

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

  Although not shown, the second symbol random number counter C4 is used for the lottery of the second symbol display device 51. The second symbol random number counter C4 is configured as a loop counter that is incremented one by one within a range of 0 to 250, for example, and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when the game ball passes through the left or right second opportunity corresponding port 46. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 in the main controller 261 will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is broadly divided into a main process that is started when the power is turned on, a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 msec), and a stop signal to the NMI terminal (non-maskable 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. 49 is a flowchart showing the timer interrupt process. This process is executed by the CPU 501 of the main control device 261 every 2 msec, for example.

  In FIG. 49, first, in step S601, read processing of the various switches 221 to 225 and the like is executed. That is, the state of various switches 221 to 225 and the like (excluding the RAM erase switch 323) connected to the main controller 261 is read, and the state of the switches 221 to 225 and the like is determined to detect detection information (winning detection) To save the information.

  Here, at each reading, whether or not the specific area switch 222 and the count switch 223 are simultaneously turned off, whether or not the four winning port switches 221 and the two second opportunity corresponding gate (gate) switches 225 are related. At the same time, it is determined whether or not the off state is configured. If the simultaneous OFF state is determined twice in succession, it is assumed that the probability that the common connectors 414 and 434 have been removed is extremely high, an abnormal signal is output, and a warning sound is output via the audio lamp control device 262. And a lamp (which may be provided separately or a top lamp or the like) is used to notify the abnormality. At the same time, this is transmitted to the hall computer as an external output signal.

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

  Thereafter, in step S604, a start winning process associated with winning in the first opportunity corresponding port 45 is executed. The start winning process will be described with reference to the flowchart of FIG. 50. In step S701, the first trigger corresponding port (start port) switch 224 detects whether or not the game ball has won a first trigger corresponding port 45 (start port). Determine by information. If it is determined that the game ball has won the first opportunity corresponding port 45, in the subsequent step S702, whether or not the number N of starting reserved balls of the first symbol display device 52 is less than the upper limit value (4 in the present embodiment). Is determined. The process proceeds to step S703 on the condition that there is a winning at the first opportunity corresponding port 45 and the number N of starting reserved balls is smaller than 4, and the number N of starting reserved balls is incremented by one.

  In subsequent step S704, a random number related to the winning of the first symbol is acquired. Specifically, the values of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 updated in step S603 are stored in the first area among the free storage areas of the reserved ball storage area of the RAM 503. Then, after the start winning process, the CPU 501 once ends the timer interruption process.

  FIG. 51 is a flowchart showing an NMI interrupt process, and this process is executed by the CPU 501 of the main controller 261 when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like. By this NMI interruption, the state of the main controller 261 at the time of power-off is stored in the backup area 503a of the RAM 503.

  That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 501 in the main controller 261. Then, the CPU 501 interrupts the control being executed and starts the NMI interrupt process of FIG. The NMI interrupt processing in FIG. 51 is stored in the ROM 502 of the main control device 261. For a predetermined time after the power failure signal SK1 is output, current is supplied from the power supply unit 541 so that the processing of the main control device 261 can be executed, and the NMI interrupt processing is executed within the predetermined time.

  In the NMI interrupt processing of FIG. 51, first, in step S801, the used registers are saved in the backup area 503a of the RAM 503, and in the subsequent step S802, the value of the stack pointer is stored in the backup area 503a. Further, in step S803, the information on occurrence of power interruption is set in the backup area 503a, and in step S804, a power interruption notification command indicating that the power has been interrupted is transmitted to another control device.

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

  The NMI interrupt process is also executed in the payout control device 311 in the same manner, and the state of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like is stored in the backup area 513a of the RAM 513. Similarly, the power is supplied from the power supply unit 541 so that the processing of the payout control device 311 can be executed for a predetermined time after the power failure signal SK1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SK1 is output from the power failure monitoring circuit 542 to the NMI terminal of the CPU 511 in the payout control device 311 and the CPU 511 interrupts the control being executed. 51 starts the NMI interrupt processing of FIG. The contents are as described with reference to FIG. 51 (except for the transmission of the power-off notification command in step S804).

  FIG. 44 is a flowchart showing an example of a main process executed by the CPU 501 in the main controller 261, and this main process is started upon reset when the power is turned on.

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

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

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

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

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

  In FIG. 45, first, in step S201, output data such as a command updated in the previous process is transmitted to each control device on the sub side. Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of acquired game balls is transmitted to the payout control device 311. Further, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 55 when the first symbol display device 52 displays the variation of the first symbol. In addition, after the first symbol variation starts, the variation pattern command → the left symbol sequence stop symbol command → the right symbol sequence stop symbol command → the middle symbol sequence stop symbol command one by one for each normal process (ie, The command is sent once every 4 msec), and the confirmation command is sent when the fluctuation time elapses. Further, the display control device 55 that has input the stop symbol command, the variation pattern command, the confirmation command, etc. determines the display mode of the first symbol display device 52 and the second symbol display device 51 based on such various commands, The display mode is displayed on the first symbol display device 52 and the second symbol display device 51.

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

  The update process of each outlier symbol counter CL, CM, CR will be described in detail. As shown in FIG. 46, in step S301, it is determined whether or not it is time to update the outlier symbol counter CL in the left symbol row. In step S302, It is determined whether or not it is time to update the middle symbol row out of symbol counter CM. If the update timing of the left symbol sequence (YES in step S301), the process proceeds to step S303, and the outlier symbol counter CL of the left symbol sequence is updated. Further, if the update timing of the middle symbol row (YES in step S302), the process proceeds to step S304, and the out-of-middle symbol counter CM is updated. Furthermore, if the update timing of the right symbol sequence (both steps S301 and S302 are NO), the process proceeds to step S305, and the out symbol counter CR of the right symbol sequence is updated. In the update of the out-of-step symbol counters CL, CM, CR in steps S303 to S305, the lower 3 bits of the R register are added to the previous counter value, and 10 is subtracted when the addition result exceeds the maximum value. Then, the calculation result is removed, and the current values of the symbol counters CL, CM, CR are used.

  According to the CL, CM, and CR update processing, the left symbol row, middle symbol row, and right symbol row outlier symbol counters CL, CM, and CR are sequentially updated one by one in one normal process. The update times of the values do not overlap. As a result, every time the normal process is executed three times, one set of the off symbol counters CL, CM, CR is updated.

  Thereafter, in step S306, it is determined whether or not the combination of the updated out symbol counters CL, CM, and CR is a reach symbol combination. It is determined whether or not it is a missed reach. If the off symbol counters CL, CM, and CR are combinations of front and rear out of reach, the process proceeds to step S308, and the combination of out symbol symbols CL, CM, and CR at that time is stored in the front and rear out of reach symbol buffer of the RAM 503. If the out symbol counters CL, CM, CR are a combination of reach other than front / back off, the process proceeds to step S309, and the combination of the out symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / back out of RAM 503. To do.

  In the case of a combination other than the reach symbol, in step S310, it is determined whether or not the combination of the symbol symbols CL, CM, CR is a symbol combination, and if it is a symbol combination, Proceeding to step S311, the combination of the off symbol counters CL, CM, CR at that time is stored in the off symbol buffer of the RAM 503. If NO in both steps S306 and S310, the symbols are aligned on the left, middle, and right, that is, it corresponds to a jackpot state. In such a case, the off symbol counters CL, CM, CR are stored in the buffer. The process is terminated without any processing.

  After the off symbol counter update process, in step S204 in FIG. 45, the winning ball counting signal and the payout abnormality signal received from the payout control device 311 are read. Thereafter, in step S205, a first symbol variation process for performing variation display of the first symbol by the first symbol display device 52 is executed. By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. The details of the first symbol variation process will be described later.

  Thereafter, in step S206, a big prize opening / closing process for opening or closing the big prize opening of the variable prize winning device 44 in the case of the big win state is executed. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has 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.

  In step S207, display control of the second symbol by the second symbol display device 51 is executed. Briefly, on the condition that the game ball has passed through the second opportunity corresponding port 46, the second symbol random number counter C4 is acquired each time and the second symbol display device 51 of the second symbol display device 51 displays the second symbol. When the symbol lottery is performed and the second symbol hit state is reached, the first opportunity corresponding port 45 is opened for a predetermined time. Although the explanation is omitted, the second symbol random number counter C4 is also updated by the timer interruption process shown in FIG. 49, like the big hit random number counter C1, the big hit symbol counter C2, and the reach random number counter C3. Yes.

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

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

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

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

  In FIG. 47, in step S401, it is determined whether or not a big hit is currently being made. Note that the jackpot includes a special game displayed on the first symbol display device 52 and a predetermined time after the special game is ended. In a succeeding step S402, it is determined whether or not the first symbol display device 52 is displaying the variation of the first symbol. Then, if it is not a big hit and is not displaying the variation of the first symbol, the process proceeds to step S403, and it is determined whether or not the number N of starting reserved balls of the first symbol display device 52 is larger than zero. At this time, if it is a big hit or if the number N of starting reserved balls is 0, this processing is terminated as it is.

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

  Thereafter, in step S406, a change start process is executed. Here, the details of the variation start process will be described using the flowchart of FIG. 48. In step S501, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1 stored in the execution area of the reserved ball storage area. To do. Specifically, whether or not the jackpot is determined based on the relationship between the jackpot random number counter value and the mode at that time, as described above, among the numerical values 0 to 676 of the jackpot random number counter C1 at the normal low probability, "337, “673” is the winning value, and “67, 131, 199, 269, 337, 401, 463, 523, 601, 661” is the winning value when the probability is high.

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

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

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

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

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

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

  Returning to the description of FIG. 47, if step S402 is YES, that is, if the variation of the first symbol is being displayed, the process proceeds to step S407 to determine whether or not the variation time has elapsed. At this time, the variation time of the first symbol is determined according to the variation pattern of the first symbol, and when this variation time has elapsed, an affirmative determination is made in step S407. In step S408, a stop symbol set for stopping and checking the fluctuation is set as a confirmation command, and then this process is terminated.

  Next, payout control executed by the CPU 511 in the payout control device 311 will be described. FIG. 52 is a flowchart showing the main process of the payout control device 311. This main process is started upon reset when the power is turned on.

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

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

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

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

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

  In FIG. 53, in step S1001, a command from the main controller 261 is acquired, and the total number of winning balls is stored. In step S1002, the launch control apparatus 312 is set for launch permission. In step S1003, the state return switch 321 is checked, and if it is determined that the state return operation has started, the state return operation is executed.

  Thereafter, in step S1004, setting of the lower pan full tank state or the lower pan full tank release state is executed in accordance with the change in the state of the lower pan 31. That is, when the lower plate 31 is full according to the detection signal of the lower plate full switch, when the lower plate is full, the lower plate full state is set and the lower plate is not full. , Set the lower pan full release state. In step S1005, setting of a tank ball absence state or a tank ball absence release state is executed in accordance with a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and the special setting for the absence of the tank ball and the setting for the no tank ball state are executed. Perform configuration.

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

  In steps S1007 to S1009, prize ball payout processing is executed. In this case, if the prize ball is not paid out and the total number of prize balls stored in step S1001 is not 0 (both NO in steps S1007 and S1008), the process proceeds to step S1009 and a prize ball control process (described later). 54) is started. Further, if the prize ball cannot be paid out or the total number of prize balls is 0 (YES in any one of steps S1007 and S1008), the process proceeds to a lending payout process.

  Thereafter, in steps S1010 to S1012, a rental ball payout process is executed. In this case, if it is not possible to pay out the rent and if a rent-out request from the card unit has been received (NO in step S1010, YES in S1011), the process proceeds to step S1012 and a renting control process (described later). 55) is started. Further, if a rental ball cannot be paid out or a rental ball payout request has not been received (YES in step S1010 or NO in S1011), the subsequent ball removal process is executed.

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

  Here, in the prize ball control process shown in FIG. 54, in step S1101, the payout motor 358a is driven to execute the prize ball payout. In subsequent step S1102, whether the rotation of the payout motor 358a is normal is determined based on the detection result of the payout rotation sensor. If the rotation of the payout motor 358a is not normal, the process proceeds to step S1103, where the payout motor 358a is driven to execute a retry process and a stop process of the payout motor 358a, and then the process returns to the payout control process of FIG.

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

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

  In the ball lending control process shown in FIG. 55, in step S1201, the payout motor 358a is driven to pay out a lending ball. In the subsequent step S1202, it is determined from the detection result of the dispensing rotation sensor whether the rotation of the dispensing motor 358a is normal. If the rotation of the payout motor 358a is not normal, the process advances to step S1203 to drive the payout motor 358a to execute a retry process and execute a stop process of the payout motor 358a, and then return to the payout control process of FIG.

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

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

  As described above in detail, according to the present embodiment, the anti-condensation films 151a and 152a are attached to the opposing surfaces of the pair of glass plates 151 and 152, so that the glass unit 150 is configured using the glass plates 151 and 152. In doing so, even if a desiccant such as silica gel is not installed between the glass plates 151 and 152, it is possible to prevent the occurrence of adverse effects such as fogging and condensation. Therefore, it is not necessary to secure an installation space for the desiccant, and the structure can be simplified.

  In particular, when the conductive layer 159b of the anti-condensation films 151a and 152a is energized and the conductive layer 159b generates heat, the plate glasses 151 and 152 and the air in the vicinity thereof are heated, so the saturated water vapor amount of the air increases. Thus, condensation can be prevented more reliably.

  In the present embodiment, for the energization, a power generation device 90c that uses a rotating member 90a that is rotated by a game ball discharged on the back side of the game board 42 is provided, and electricity generated by this is used. It is said. Therefore, the kinetic energy possessed by the game ball can be used effectively without causing any trouble in the game.

  In addition, as a result of sticking the anti-condensation films 151a and 152a to the opposing surfaces of the pair of plate glasses 151 and 152, the mechanical strength of the plate glasses 151 and 152 is reinforced, so that a player hits the plate glass. In addition, it is possible to prevent the glass plates 151 and 152 from being damaged. Further, the anti-condensation films 151a and 152a are on the opposing surfaces of the pair of glass plates 151 and 152, and the player or game ball is not directly touched. The Further, by sticking the dew condensation prevention films 151a and 152a, it is possible to effectively prevent noise such as a sound that the game ball hits the plate glass on the game board 42 side.

In addition, on the back side of the front frame set 14, attached portions 180 are provided at a plurality of locations corresponding to the attaching portions 155, and the glass units 150 are attached by attaching the attaching portions 155 to the attached portions 180. It is fixed and detachable. Therefore, if the front frame set has the same mounted portion 180, the glass unit 150 can be reused. As a result, even if the pachinko machine is replaced in the hall, the glass unit 150 can be used for another pachinko machine, which is highly economical for the hall side.
In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, the glass unit 150 is constituted by the pair of plate glasses 151 and 152. Of course, it is also conceivable that the glass unit is constituted by using three or more plate glasses. Moreover, although plate glass 151,152 was used, what is necessary is just a transparent body which can visually recognize a game area | region, for example, using resin-made transparent bodies is also considered.

(B) In the said embodiment, it is desirable for the film for anti-condensation to have an electromagnetic wave shielding function. As the electromagnetic wave shielding function, it is desirable to provide a lattice-shaped conductive metal layer on the dew condensation prevention film from the viewpoint of achieving both a high performance electromagnetic wave shielding function and visible light transmission performance. In addition, the dew condensation preventing film is not limited to the above-described configuration including the hydrophilic layer, the insulating layer, and the conductive layer, and may be a configuration in which a film-like material having a water absorption function is simply installed on the substrate. Examples of the material having a water absorption function include a hydrophilic polymer film or a film coated with a hydrophilic polymer film.

(C) In the above embodiment, the configuration in which the anti-condensation films 151a and 152a are attached to the plate glasses 151 and 152 as the film-like dew condensation prevention means is adopted, but even if the film-like dew condensation prevention means other than the film is attached. Good. On the other hand, for example, by attaching linear dew condensation prevention means such as the heating pattern shown in FIG. 18 to the opposing surfaces of the plate glasses 151 and 152, the heating pattern is made conductive, so that the plate glass 151, You may comprise so that 152 may be heated.
The heating pattern may be a shape attached to the game board 42 and the outer shape of the symbol display device, or may be along the outer shape of a pattern such as a cell image of the game board 42. Even in the case of conducting the heat generating pattern, it is desirable to use electricity generated by the power generation device using the rotating member 220a rotated by the dropped game ball.

  (D) In addition to the power generation device 220c using the rotating member 220a rotated by the dropped game ball, for example, a piezoelectric element that receives the game ball may be used. Then, electricity generated in the piezoelectric element may be supplied to the conductive film or the heating pattern to heat the plate glass. In this case, it is desirable that the piezoelectric element is disposed in, for example, a discharge path for receiving game balls discharged from the out port or a winning port to the back side of the game board, or a tank for storing the game balls.

  (E) In the above embodiment, the heating means for heating the glass sheet is configured to heat with electricity supplied to the conductive film or the heating pattern. For example, the blowing means provided on the back side of the gaming machine And the structure which blows the warm air of the back side of a game machine on a plate glass with the wind guide pipe which connects between the said ventilation means and plate glass may be employ | adopted.

  (F) You may implement as a different type of pachinko machine etc. from the said embodiment. For example, once a big hit, a pachinko machine (commonly known as a two-time right, a three-time right, etc.) that increases the expected value of the big hit until a big hit state occurs (for example, twice or three times). May also be implemented. Further, it may be implemented as a pachinko machine that enters a special gaming state on the condition that a game ball is awarded in a predetermined area after the big hit symbol is displayed. Furthermore, the present invention can be applied to a pachinko machine called a blade. In addition to pachinko machines, the present invention can also be implemented as various game machines such as an arrangement ball machine and a similar sparrow ball.

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