  Next, the configuration of the pachinko machine 10 will be roughly divided into an outer frame 12, an inner frame 13, a game board 16, a front frame 14, a lower tray unit 15, and a glass unit 17, and then the configuration on the back side of the pachinko machine 10. Will be described. First, the configuration of the outer frame 12 will be described with reference mainly to FIGS. 2 and 4. Here, FIG. 4A is a perspective view of the outer frame 12, and FIG. 4B is an enlarged perspective view of the periphery of the receiving bracket 23 of the outer frame 12.

  As shown in FIG. 2, the pachinko machine 10 is provided with an outer frame 12 that forms an outer shell, and the inner frame 13 is supported by the outer frame 20 so as to be opened and closed. In the game hall, the outer peripheral surface of the outer frame 20 is fixed to an installation location called an island of the game hall. Since the inner frame 13, the front frame 14, and the lower dish unit 15 are configured to be openable to the front side with respect to the outer frame 12, the inner frame 13, the front frame 14, and the lower dish unit 15 are not touched from the front side of the pachinko machine 10. Inspection and adjustment are performed with the inner frame 13 and the like open to the front side with respect to the outer frame 12.

  The outer frame 12 is made of a wooden plate material that forms four sides on the top, bottom, left, and right to form a rectangular wooden frame 20 as a whole, and hinges 21 and 22 and receiving brackets 23 and 23 are attached to the wooden frame 20. is there. The joint portion of the wooden frame 20 is fixed by a detachable fastener such as a small screw, and a part of the wooden frame 20 can be easily reused as compared with a structure that is fixed using a nail or a rivet. Yes. In the present embodiment, the outer dimension of the outer frame 12 is 809 mm (inner dimension of about 710 mm), and the outer dimension of the left and right direction is 518 mm (inner dimension of about 480 mm). The outer frame 12 may be made of a light metal such as aluminum or a resin.

  As shown in FIG. 4A, metal upper hinges 21 and lower hinges 22 are attached to the outer frame 12 at two upper and lower portions on the left side when viewed from the front to support the inner frame 13. The inner frame 13 is supported to be openable and closable by using the side on which the hinges 21 and 22 are provided as an opening / closing axis.

  The metal fittings 23 of the outer frame 12 are screwed into the upper and lower two places on one side of the inner side of the wooden frame 20 and away from the hinges 21 and 22 with screws. Each receiving bracket 23 is formed by bending a metal plate, and as shown in FIG. 4B, a mounting portion 23a that is in close contact with the inner surface of the outer frame 12, and the inner surface side of the outer frame 12 from the mounting portion 23a. An engaging portion 23b that rises vertically toward the end, and a protruding portion 23c that protrudes toward the closing direction side of the inner frame 13 (upper left side in FIG. 4B) at the distal end side of the engaging portion 23b. And. The front end portion of the inner frame collar member 411 (see FIG. 23) formed so as to project from the inner frame 13 in a hook shape is caught in the engaging portion 23 b of the receiving metal 23, and the inner frame 13 is closed.

  The protruding portion 23c of the metal fitting 23 has an inner frame flange toward the inner surface side (the lower left side in FIG. 4B) of the outer frame 12 in a state where the inner frame 13 is closed with respect to the outer frame 12. It is formed so as to protrude more than the length overlapping the tip portion protruding downward of the member 411. For this reason, the movement of the distal end portion of the inner frame collar member 411 toward the inner surface side of the outer frame 12 is restricted by the protruding portion 23c, and the protruding amount of the metal fitting 23 toward the inner surface side of the outer frame 12 is reduced.

Can be manufactured, and the appearance quality of the pachinko machine 10 can be improved while effectively reusing the wooden frame 20.

  On the upper surface of the decorative plate 24, metal sliding plates 25 and 26 are provided at two locations, that is, an end portion on the side separated from the hinge 22 and a central portion. Even if the inner frame 13 in the open state falls downward with respect to the outer frame 12 due to its own weight, when the inner frame 13 is closed, its lower surface is lifted while being rubbed against the sliding plates 25 and 26, and the inner frame 13 Guided to a fixed position. For this reason, it is not necessary for the operator to perform the closing operation while lifting the inner frame 13, and the convenience of the opening / closing operation of the inner frame 13 is enhanced. In addition, compared to the case where a part that guides the inner frame 13 to a fixed position is formed by a resin or wooden part, parts are prevented from being scraped or damaged due to rubbing due to repeated opening and closing operations. The opening / closing operation of the inner frame 13 can be easily performed over a long period of time.

  One of the two sliding plates 25, 26 is provided at an end portion on the side away from the hinges 21, 22 serving as the opening / closing shaft of the inner frame 13. For this reason, both lower end sides of the inner frame 13 are supported by the metal lower hinge 22 and the sliding plate 26, and the inner frame 13 is guided to a fixed position in a more stable state. Further, the other sliding plate 25 is provided at a substantially intermediate position between the hinge 22 and the sliding plate 26, and the most easily depressed portion is guided by the support of the hinge 22 and the sliding plate 26 provided at the end. It becomes. Thus, by providing the two sliding plates 25 and 26 at the end portion and the central portion on the upper surface of the decorative plate 24 on the side away from the hinge 22, the inner frame 13 can be reliably guided at a fixed position, Even if the weight applied to the inner frame 13 increases due to a large amount of game balls entering the upper plate 201 or the lower plate 301, the opening / closing operation of the inner frame can be easily performed.

  On the back side of the upper surface of the decorative plate 24, a rib 27 is provided so as to protrude upward to a position overlapping the lower end portion of the inner frame 13 along the front-rear direction of the pachinko machine 10. In addition, a groove 27 a that is recessed toward the back side along the upper surface of the decorative plate 24 is formed at the base portion of the rib 27, and the upper end portion of the rib 27 is formed so as to protrude toward the front side of the pachinko machine 10. For pachinko machines, fraudulent acts that are performed by inserting a thin plate-like tool or the like through a gap between members are frequently reported. However, in the pachinko machine 10 according to the present embodiment, a tool from the lower side of the inner frame 13 is reported. Since the rib 27 prevents the act of inserting etc., fraudulent acts can be prevented. Further, the tool inserted from between the inner frame 13 and the decorative plate 24 is likely to be fitted into the groove 27a provided at the base portion of the rib 27, which makes it more difficult to cheat.

  The height of the ribs 27 on the upper surface of the decorative plate 24 is set lower than the radius of the game ball with respect to the upper surface of the decorative plate 24. For this reason, even if a game ball is on the upper surface of the decorative plate 24 when the inner frame 13 is closed, the game ball gets over the rib 27 after being sandwiched between the lower end portion of the inner frame 13 and the rib 27. Therefore, the provision of the rib 27 prevents illegal actions, and the game ball is not sandwiched between the rib 27 and the inner frame 13 so that the trouble of reclosing the inner frame 13 does not occur. Convenience for the opening / closing operation can be kept high.

The game balls that have not entered any of the winning openings 63, 64, 65a are guided through the out opening 66 to a ball discharge path (not shown). A number of nails are planted on the game board 16 in order to appropriately disperse and adjust the falling direction of the game ball, and various members (instruments) such as a windmill are arranged.

  The variable display device unit 80 includes a light emitting diode (hereinafter abbreviated as “LED”) that displays the second symbol (ordinary symbol) in a variable manner with the passage of the game ball at the second entrance 67 as a trigger. There are provided a two symbol display device 82 and a first symbol display device 81 for variably displaying the first symbol (special symbol) triggered by winning at the first entrance 64. The second symbol display device 82 includes a second symbol display portion 83 and a holding lamp 84, and each time a game ball passes through the second entrance 67, the display symbol 83 displays a second symbol (second symbol). As the symbol “○” and “×” symbol are alternately lit, the variable display is performed, and when the variable display stops at a predetermined symbol (in this embodiment, “○” symbol) The 1 entrance 64 is configured to be activated (opened) for a predetermined time. The number of times that the game ball passes through the second entrance 67 is held up to a maximum of 4 times, and the number of times the game ball is passed is displayed on the hold lamp 84. Note that the variation display of the second symbol is performed by switching on and off of a plurality of lamps in the display unit 83 as in the present embodiment, and a part of the first symbol display device 81 is used. May be performed. Similarly, the hold lamp 84 may be turned on by a part of the first symbol display device 81.

  In addition, when a game ball enters the first entrance 64 while the first symbol display device 81 is performing the variable display of the first symbol, the number of times that the ball has entered is suspended up to four times, The number of times of holding is displayed by the number of lighting of the holding lamp 85. Four holding lamps 85 are provided for the maximum number of holdings, and are arranged symmetrically above the first symbol display device 81. In the present embodiment, the winning entry to the first entrance 64 and the passing through the second entrance 67 are configured to be held up to 4 times each, but the maximum holding number is limited to 4 times. Instead, it may be set to 3 times or less, or 5 times or more (for example, 8 times). In addition, the hold lamp 85 is deleted, and the number of times the variable display is held based on the winning at the first entrance 64 is numerically held in a part of the first symbol display device 81, or the area divided into four is held. You may make it display in a different aspect (for example, a color and a lighting pattern) by the frequency | count.

  The display content of the first symbol display device 81 is controlled by a display control device 505, which will be described later, and for example, three symbol sequences of left, middle, and right are displayed. Each symbol row is composed of a plurality of symbols, and these symbols are vertically scrolled for each symbol row so that the first symbol is variably displayed on the display screen of the first symbol display device 81. In the present embodiment, the first symbol display device 81 is composed of a large liquid crystal display of 8 inch size, and the variable display device unit 80 surrounds the outer periphery of the first symbol display device 81 so as to surround the center frame 86. Is arranged.

  The variable winning device 65 opens and closes a specific winning port 65a formed in a horizontally long rectangular shape at the center thereof. Specifically, a horizontally long rectangular opening / closing plate that covers the specific winning opening 65a, and a solenoid for opening / closing driving the lower side of the opening / closing plate as an axis are provided. The special winning opening 65a is normally closed so that a game ball cannot win or is difficult to win. In the case of a big hit, the solenoid is driven to tilt the opening / closing plate downward and the game ball temporarily forms an open state in which the game ball is likely to win the specific winning opening 65a. It operates so that these states are repeated alternately.

  The two rails 61 and 62 provided on the game board 16 are provided for guiding the game balls launched from the ball launch unit 90 to the upper part of the game board 16. A game ball launched in accordance with the turning operation of the operation handle 310 is guided to the game area via a path sandwiched between the two rails 61 and 62. Both rails 61 and 62 are made of a stainless steel metal band, and the inner rail 61 is fixed to the base plate 60 in a state of being bent into an annular shape excluding the upper right semicircle. The outer rail 62 is fixed to the base plate 60 such that a part (mainly the left side portion) faces the inner rail 61. The inner rail 61 and the outer rail 62 mainly constitute a guide rail, and a ball that guides the game ball to the game area by a portion where the rails 61 and 62 are parallel to each other at a predetermined interval (a portion on the left side). A guide passage is formed.

  A return ball preventing member 68 is attached to the tip of the inner rail 61 (upper left portion in FIG. 3). As a result, it is possible to prevent a situation in which the game ball guided to the upper portion of the game board 16 from the ball guide passage between the inner rail 61 and the outer rail 62 once again returns to the ball guide passage. A resin arc member 70 formed by providing an arc connecting the rails on the inner surface side between the lower right end of the inner rail 61 and the upper right end of the outer rail 62 is a base. The plate 60 is driven and fixed. A return rubber 69 is attached to the front end portion of the outer rail 62 (upper right portion in FIG. 3) at a position corresponding to the maximum flying portion of the game ball. The game ball fired at a predetermined momentum or more hits the return rubber 69 and is bounced back toward the center while the momentum is attenuated.

  In the lower right corner and the lower left corner of the game board 16, there are provided adhering spaces K1, K2 for adhering seals or plates such as stamps. Since the game board 16 itself is provided with sticking spaces K1, K2 such as stamps, the game board 16 can be uniquely identified by the stamps, etc., and the replacement to the illegal game board 16 can be easily found. Can do.

  Next, the game area will be described. The game area is a substantially circular area formed on the front surface of the game board 16 and defined by the two rails 61 and 62 and the arc member 70. In this embodiment, the game area is a guide rail that is a parallel part of the inner rail 61 and the outer rail 62 in the area surrounded by the inner rail 61, the outer rail 62, and the arc member 70 when viewed from the front of the pachinko machine 10. The area is excluded. Therefore, in the case of a game area, the guide rail portion is not included, and the left limit position toward the game area is specified by the inner rail 61 instead of the outer rail 62. Similarly, the right limit position toward the game area is specified by the arc member 62. Further, the lower limit position of the game area is specified by the inner rail 61. Further, the upper limit position of the game area is specified by the outer rail 62.

  In the pachinko machine 10, the distance from the upper end of the game area (the uppermost point of the outer rail 62) to the lower end of the game area (the lowermost point of the inner rail 61) is 445 mm (about 58 mm longer than the conventional product). The distance from the left end (the extreme left position of the inner rail 61) to the right end of the game area (the extreme right position on the inner surface of the arc member 70) is 418 mm (about 50 mm longer than the conventional product). That is, the game area of the pachinko machine 10 is configured to be much larger than that of the past by extending in the left-right direction and the up-down direction. Therefore, a windmill, the second entrance 67, a plurality of nails (such as a guide nail for guiding the game ball to the center), and other accessories can be arranged in various ways, and the behavior of the game ball can be varied. You can make the ball game more interesting.

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

  In the present embodiment, the ratio of the area of the game area to the surface of the game board 16 is about 70%, which is much larger than the conventional area ratio. Since the area ratio of the game area to the surface of the game board 16 has been only about 50% in the past, it can be said that the game area is considerably expanded on the premise that the game board 16 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 16 must be the same, the surface of the game board 16 as described above. Increasing the ratio of the area of the gaming area to about 20% is very significant from the viewpoint of expanding the gaming area. Here, the ratio is preferably at least 60% or more. More preferably, it is 65% or more, More preferably, it is 70% or more. Further, if it is 75% or more exceeding the case of this embodiment, it is more desirable. Furthermore, it may be 80% or more.

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

  The second entrances 67 (through gates) located on both sides of the variable display device unit 80 have a guide mechanism for bringing the passed game ball to the center of the game area. This guide mechanism is configured by providing an inclined surface that descends toward the center of the game area below the second entrance 67. As a result, even if the game area is expanded in the left-right direction by providing a large LCD at the center of the game area in the variable display device unit 80, the game ball is moved to the first entrance 64 on the center side of the game area or variable. It is possible to guide to the winning device 65, and as a result, it is difficult to win a game ball due to the expansion of the game area, or the game ball's path is narrowed and the behavior of the game ball becomes monotonous. Can be suppressed.

  Next, the ball launch unit 90, the passage forming member 36, and the relay board 38 which are attached to the lower part on the front side of the inner frame base 30 and constitute a part of the inner frame 13 will be described mainly with reference to FIGS. To do. 6 is a front view of the ball launching unit 90, FIG. 7 is a perspective view thereof, and FIG. 8 is an exploded perspective view thereof. 9 is a perspective view of the ball launching unit 90 in a state where the opening / closing member 102 constituting the ball feeding mechanism 94 is opened, and FIG. 10 is a perspective view of the ball feeding mechanism with the lid member 103 removed from the state of FIG. FIG. 9 is a perspective view of a ball launch unit 90 showing the internal configuration of 94.

  The ball launch unit 90 includes a base plate 91 fixed to the attachment surface 30f at the lower part of the inner frame base 30 with screws, a launch solenoid 92 attached to the base plate 91, and a longitudinal direction of the launch solenoid 92 on one end side of the launch solenoid 92. A launch rail 93 having a substantially M-shaped cross section that is attached and fixed to the base plate 91 so as to extend in parallel with the base plate 91, and guides the game balls one by one to the base end portion (the end portion on the launch solenoid 92 side) of the launch rail 93 A ball feeding mechanism 94 for guiding, and a positioning member 95 (see FIG. 9) attached to the base plate 91 so as to support and position the game ball placed on the base end portion of the firing rail 93 are provided. Yes.

  The base plate 91 is formed by pressing a metal flat plate such as a zinc alloy, and is fixed by screws 96 in a state of being in close contact with the mounting surface 30 f of the inner frame base 30. As shown in FIG. 8, the base plate 91 is provided with a fastening hole for inserting the screw 96, and the boss 91a and the bolt 91b for fixing the firing solenoid 92 and the firing rail 93 are secured. The boss 91c is fixed.

  The mounting position of the base plate 91 is desired to be highly accurate so as to be stable with respect to the inner frame base 30 even when many pachinko machines 10 are manufactured. When the relative position with respect to the game board 16 changes for each pachinko machine 10, the jump amount of the game ball fired by the launch solenoid 92 differs accordingly, and the jump amount of the game ball corresponding to the turning operation of the operation handle This is because each pachinko machine 10 becomes unstable. In the pachinko machine 10 of this embodiment, the base plate 91 is made larger than the conventional one, and the relative mounting position with the inner frame base 30 is stabilized. Specifically, the lower end of the base plate 91 extends below the pivot axis (position indicated by AH in FIG. 5) of the operation handle 310, and the right end thereof is substantially the same as the right end of the game board 16, Its left end extends to the left side from the out port 66 so as to cross the center of the game area, and its upper end extends to a position close to the lower end of the game board 16. Further, the number of screws 96 for fixing the base plate 91 is increased (six) from the conventional one. Further, the fastening position of each screw 96 (see FIG. 5) is separated from the conventional one. For example, the fastening position of the lower screw 96 is below the rotation axis AH of the operation handle 310, and the mounting position is stable. We are trying to make it.

  The launch rail 93 guides the game ball immediately after being fired by the launch solenoid 92, and extends to a boss 91c fixed to the base plate 91 so as to extend linearly while maintaining a predetermined launch angle (launch angle). It is fixed with screws (not shown). A game ball that is launched in accordance with the turning operation of the operation handle 310 is first launched obliquely upward along the launch rail 93, and then through the guide rail formed between the two rails 61 and 62 as described above. Guided to the game area.

  Here, in the case of this pachinko machine 10, it has already been described that the game area is greatly expanded as compared with the conventional case, but in such a configuration, the distance between the launch position of the game ball and the game area becomes closer and the launch rail becomes shorter. It tends to be. If the launch rail 93 is short, the ball guiding distance is reduced and the variation of the launch ball is increased. Therefore, a device for stabilizing the launch ball is required. In this embodiment, the launch position of the game ball is lowered and the inclination angle (launch angle) of the launch rail 93 is made somewhat larger than that of the existing one (that is, the launch rail 93 is raised). The length of the ball is about 240 mm to ensure a sufficiently long ball guiding distance. Thereby, the game ball launched from the launching device can be guided to the guide rail in a more stable state. In this case, in particular, the launch rail 93 is formed to extend from the launch position of the game ball hit by the launch solenoid 92 to a position beyond the center position (out port 66) of the game area.

  Further, in the pachinko machine 10, as a launching device for launching a game ball, a single unit solenoid (launch solenoid) in which a linear solenoid is housed in a case member, instead of a combination of a motor and a launching rod that are generally used conventionally. 92 is adopted. The firing solenoid 92 is provided with a metal plunger 92a disposed parallel to the firing rail 93 and a longitudinal direction, and a resin cap 92b covering the tip of the plunger 92a. As the material of the cap 92b, a polyester-based thermoplastic elastomer is employed in the present embodiment. While the player is turning the operation handle 310, the firing solenoid 92 repeats excitation and de-excitation every predetermined time, and the plunger 92a is repeatedly moved up and down accordingly. When the plunger 92 a protrudes, the game ball positioned on the firing rail 93 by the positioning member 95 is launched toward an obliquely upward direction toward the firing rail 93. A variable resistor that is linked to the operation handle 310 is connected to the firing solenoid 92, and the protruding speed of the plunger 92a is adjusted based on the operation amount of the operation handle 310 (the stroke amount is substantially constant). The speed and thus the jump amount is adjusted by the rotation amount of the operation handle 310.

  As shown in FIG. 8, the firing solenoid 92 is fixed to a pair of bosses 91a and bolts 91b erected on the base plate 91 by attaching bolts 97 and nuts 98 thereto. The firing solenoid 92 is provided with a fastening hole 92c through which the bolts 91b and 97 are inserted at positions corresponding to the boss 91a and the bolt 91b. In the ball launch unit 90, the height of the launch solenoid 92 relative to the base plate 91 is made different by adjusting the tightening of the bolts 97 and nuts 98 provided above and below the launch solenoid 92, so that the plunger 92a and the launch rail 93 The relative mounting position can be adjusted, and the hitting point of the game ball can be adjusted. Even if there is a variation in manufacturing and assembling of each part at the time of manufacturing the pachinko machine 10, the ball launch unit 90 is assembled to the pachinko machine 10 and then the bolt 97 and the nut 98 are adjusted to reduce the flying amount of the game ball. Can be adjusted. The firing solenoid 92 is entirely disposed inside the outer peripheral edge of the base plate 9l. When the ball launching unit 90 is assembled to the inner frame base 30 from the base plate 91 side, the firing solenoid 92 is another component. It is prevented from being caught and damaged.

  The positioning member 95 is a member for supporting the game ball placed on the right end portion (base end portion) of the firing rail 93 and positioning the game ball at the hitting position, as shown in FIG. The base plate 91 is formed so as to protrude in a columnar shape on the surface side on which the firing rail 93 is provided. The positioning member 95 is provided with a fastening hole penetrating along the axial direction, and the positioning member 95 is screwed to the base plate 91 by inserting a screw into the fastening hole. Here, the fastening hole of the positioning member 95 is formed not at the center of the columnar shape but at an eccentric position. For this reason, it is possible to slightly change the hitting position of the game ball placed on the firing rail 93 by rotating the positioning member 95 appropriately and then tightening the screw, and at the time of manufacturing and manufacturing the pachinko machine 10 Later, it is possible to easily adjust the jump amount of the game ball.

  The ball feeding mechanism 94 feeds the game balls continuously guided from the upper plate 201 one by one to the base end portion of the firing rail 93. The ball feeding mechanism 94 is made of a resin base member 101 fixed to the base plate 91 so as to cover the upper part of the firing solenoid 92, and is pivotally supported on one side (right side in FIG. 6) of the base member 101 to open and close. And a resin opening / closing member 102 configured to be capable of being used. The base member 101 is integrally formed with a locking claw 101a toward the front side where the opening / closing member 102 is provided. The opening / closing member 102 has a locking claw 101a in a closed state overlapping the front surface of the base member 101. A locking hole 102a is formed in which is caught. Normally, the opening / closing member 102 is in a closed state in which one side is pivotally supported by the pedestal member 101 and the other side is locked to the pedestal member 101 by a locking hole 102a and overlaps and is fixed to the front surface of the pedestal member 101. This closed state is released by removing the locking claw 101 a of the base member 101 from the locking hole 102 a of the opening and closing member 102, and the opening and closing member 102 can be opened forward with respect to the base member 101. Further, the opening / closing member 102 can be slid upward to be detached from the pedestal member 101 by opening to the maximum with respect to the pedestal member 101.

  The lower part of the pedestal member 101 is formed in a shape inclined downward toward the front side of the lower dish unit 15 while covering the upper gap between the lower dish unit 15 and the mounting surface 30f of the inner frame base 30. Further, on the left side of the pedestal member 101 when viewed from the front, the passage forming member 36 covers the upper gap between the lower plate unit 15 and the mounting surface 30f of the inner frame base 30 on the left side of the pedestal member 101 and the front surface of the lower plate unit 15. It is formed in a shape that is inclined downward toward the side. For this reason, when the front frame 14 is opened, even if the game ball falls on the part of the ball launching unit 90, the game ball does not enter the back side of the lower dish unit 15 and flows out to the front side. .

  As shown in FIG. 6, an introduction port 102b for introducing a game ball guided from the upper plate 201 is provided at the front end of the opening / closing member 102 as viewed from the front, and the game ball is introduced from the introduction port 102b. Is introduced to the back side of the opening / closing member 102. As shown in FIG. 9, a lid member 103 is detachably attached to the back surface side of the opening / closing member 102, and the lid magnet 103 covers the electromagnet 104 and the delivery member 105. The electromagnet 104 and the delivery member 105 are members that operate to send out the game balls one by one. As shown in FIG. 10, the electromagnet 104 faces upward in the accommodation space recessed in the opening / closing member 102. They are arranged side by side.

  The delivery member 105 is a resin-made member that is pivotally supported by a pin so that one side of the introduction port 102b can swing up and down with respect to the opening / closing member 102, and only one game ball is provided on one side of the introduction port. A holder portion 105a that is recessed so as to be accommodated is provided. A metal piece 106 is attached to the upper side portion connecting the shaft portion through which the pin is inserted and the holder portion 105 a so as to face the electromagnet 104.

  When the electromagnet 104 is turned on (excited), the metal piece 106 is pulled so as to stick to the electromagnet 104, and the delivery member 105 rotates upward. When game balls are continuously introduced from the introduction port 102b, the top game ball is accommodated in the holder portion 105a and the vertical movement is restricted, and the subsequent game balls are supported by the game balls accommodated in the holder portion 105a. The flow is regulated.

  When the electromagnet 104 is turned off (de-energized) in a state where the game ball is accommodated in the holder portion 105a, the delivery member 105 rotates downward by its own weight, and the game ball accommodated in the holder portion 105a flows downward. To do. At this time, since the transition of the subsequent game ball to the holder portion 105 a is restricted by the upper side of the delivery member 105, only one ball accommodated in the holder portion 105 a is sent downward by the vertical movement of the delivery member 105. The game ball delivered downward is guided onto the firing rail 93 via the delivery port 102c (see FIG. 9) formed by the opening / closing member 102 and the lid member 103. Therefore, when the excitation and de-excitation of the electromagnet 104 are repeated, the game balls are guided one by one onto the launch rail 93 in synchronization with the repetition, and the launch solenoid 92 is excited in synchronization with the on / off of the electromagnet 104. Thus, the game balls on the launch rail 93 can be launched one by one toward the game area.

  Next, the passage forming member 36 provided on the front side of the inner frame 13 will be described with reference mainly to FIG. The passage forming member 36 includes a lower tray discharge passage (not shown) for discharging the game balls to the lower plate 301 when the upper plate 201 is full, and a foul ball for discharging the foul balls to the lower plate 301. It is a member for forming a passage (not shown). Here, the foul ball means a game ball that returns to the launch rail 93 side without reaching the entrance of the game area where the return ball prevention member 68 is located because the launch force (launch force) at the time of launch is weak. Yes.

  A gap of about 40 mm is formed between the launch rail 93 and the rails (guidance rails) 61 and 62 on the front surface of the game board 16, and a foul ball passage is provided below the gap. A passage forming member 36 made of a transparent resin is fixed to the mounting surface 30f of the inner frame base 30 with screws on the front surface of the inner frame 13 and on the left side of the ball launch unit 90. The passage forming member 36 is provided with a groove that opens toward the mounting surface 30 f side of the inner frame 13, and a foul ball passage is formed by the groove and the mounting surface 30 f of the inner frame base 30. The foul ball passage joins a lower tray discharge passage that guides game balls overflowing from the upper plate 201 to the lower plate 301 from the middle. A lower tray discharge port 36a that protrudes in a cylindrical shape from the mounting surface 30f toward the front side of the inner frame base 30 is provided at the most downstream portion of the lower tray discharge passage. Is discharged from the lower plate discharge port 36a to the lower plate 301.

  In the middle of the discharge passage, a full tank sensor (not shown) for detecting that the lower tray 301 is full of game balls is provided so as to form a part of the passage bottom surface. When a large amount of game balls are paid out in a short period of time, game balls start to accumulate in the lower plate 301 after the upper plate 201 is full. After that, even if the game balls continue to be paid out, if the game balls on the lower plate 301 are not pulled out, the game balls will start to collect in the discharge passage. It is stopped by the control of the payout and emission control device 611 (see FIG. 23). If the game ball continues to be paid out even if the discharge passage is full, the lower plate 301 overflows and it becomes difficult to continue the game, or the game ball gets stuck in the gear for paying out the game ball This is because problems are likely to occur. When the full tank of the discharge passage is detected by the full tank sensor, an error message “please remove the ball” is repeatedly output from the speaker SP (see FIG. 2) under the control of the payout launch control device 611. The player can be shown that the game balls have accumulated in the lower plate 301, and can be prompted to take out the game balls from the lower plate 301.

  An upper tray discharge port 36b for discharging game balls to the upper plate 201 is provided in the upper left part of the passage forming member 36, and the inner frame base 30 is used for paying out game balls to the upper plate discharge port 36b. There is a payout exit. The payout port of the inner frame base 30 connects the back surface and the front surface of the inner frame base 30 and is connected to a payout device 658 (see FIG. 20) provided on the back surface side of the inner frame 13. The payout opening and the upper tray discharge port 36b communicate with the upper plate 201 in a state in which the front frame 14 is closed, and the game ball is discharged (paid out) to the upper plate 201 through the discharge port and the upper plate discharge port 36b. . An open / close shutter 37 is attached to the upper plate discharge port 36b. When the front frame 14 is opened (the state shown in FIG. 2), the shutter 37 closes the upper plate discharge port 36b by an urging force such as a spring. . When the front frame 14 is closed, the shutter 37 is tilted toward the inner frame base 30 and pushed open by a ball passage rod 241 (see FIG. 2) provided on the back surface of the front frame 14. Therefore, in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 201 is directly provided on the front frame 14, the game ball passing through the payout opening of the inner frame base 30 is opened when the front frame 14 is opened. Inconveniences such as spilling down on the front surface of 13 can be prevented.

  On the lower side of the lower plate discharge port 36a in the passage forming member 36, a rib 36c having a length contacting the lower surface of the inner frame 13 is provided, and the mounting surface 30f of the inner frame base 30 formed in a flat plate shape is reinforced. Has been. Further, a gap through which the wiring passes is provided between the rib 36c and the mounting surface 30f, and the rib 36c is used as a holder for electric wiring.

  A relay board 38 is accommodated in the lower left corner of the front surface of the inner frame base 30. On the relay board 38, wiring of electrical components (touch sensor and variable resistor inside the operation handle 310 and the speaker SP) provided in the lower tray unit 15 and a control device (payout launch control) provided on the inner frame 13 side are provided. It is a part which connects the apparatus 611 and the audio | voice lamp control apparatus 562), and the insertion port (not shown) connected with the connector provided in the wiring cord front end by the side of the lower pan unit 13 is provided. Since the electrical connection between the lower tray unit 15 and the inner frame 13 is gathered on the relay substrate 38, the wiring work when assembling and removing the lower tray unit 15 is simplified, and the pachinko machine 10 is assembled and removed. Disassembly is easy. In addition, the relay board 38 is provided with a switch for adjusting the volume of the speaker SP in two levels, and the volume can be easily adjusted without opening the inner frame 13. The wiring from the relay board 38 to the control device provided on the back side of the inner frame 13 is arranged along the lower end of the mounting surface 30f of the inner frame base 30 and on the inner side of the rib 36c of the passage forming member 36. The inner frame base 30 is routed around the back surface of the inner frame 13 through a wiring hole 30 h formed in the lower right front corner of the front surface.

  Next, the configuration of the front frame 14 will be described with reference to FIGS. 1, 2, 11, and 12. FIG. 11A is a rear view of the front frame 14, and FIG. 11B is a cross-sectional view taken along the line RR in FIG. 11A. FIG. 12 is a cross-sectional view of the outlet portion of the upper plate 201 that sends out the game ball to the ball launching unit 90. FIG. 12 (b) shows a state in which the front frame is closed.

  The front frame 14 is mainly configured by a front frame base 200 made of ABS resin formed in a rectangular shape, and the front frame base 30 has a central portion so that most of the game area can be visually recognized from the outside. A window portion 14c having an elliptical opening is provided. Moreover, as shown in FIG. 1, the upper plate | board 201 as a ball receiving tray is integrally provided under the window part 14c. The upper plate 201 temporarily stores the game balls and guides them to the ball launch unit 90 while aligning them in a row. In the conventional pachinko machine, a front decorative frame that can be opened and closed with respect to the inner frame is provided below the front frame, and an upper plate is provided on the front decorative frame, but in this embodiment, the front decorative frame is omitted, An upper plate 201 is provided directly on the frame 14. This is because the front frame 14 of the present embodiment includes a window portion 14c that is largely oval shaped so that a game area formed larger than a conventional pachinko machine can be visually recognized from the outside. The upper plate 201 is integrally formed with the front frame 14 in order to improve the strength of the plate as much as possible. Similar to the lower plate 301, the upper plate 201 has at least a surface layer formed of a flame-retardant ABS resin.

  The window portion 14c of the front frame 14 has a vertically elongated elliptical shape in which a substantially central portion on the left and right sides thereof is curved relatively gently as compared with the upper and lower sides. Since the front frame base 30 forming the window portion 14c is longer in the vertical direction than in the horizontal direction, the front frame base 30 has a narrow width that is easily broken at the top, bottom, left and right of the front frame base 200 while opening the window portion 14c. The part which becomes can be provided comparatively widely, and it is easy to ensure intensity | strength. In addition, you may form in the linear form, without curving the substantially center part of the left-right side of the window part 14c.

  In the present embodiment, the upper end of the opening of the window portion 14c coincides with the uppermost portion of the outer rail 62 (the upper end of the game area), and the shortest distance between the upper end of the opening and the upper end of the front frame 14 (the so-called upper frame portion). The vertical width is about 50 mm. Compared to the prior art having an upper frame width of about 85 mm to 95 mm, the upper frame width is remarkably shortened, so that it is easy to secure the upper area of the game area and the large variable display device unit 80 can be disposed relatively upward. The distance from the upper end of the front frame 14 is desirably 80 mm or less, more desirably 70 mm or less, and further desirably 60 mm or less. Of course, as long as a predetermined strength can be ensured, it may be 50 mm or less.

  Further, the shortest distance between the left end of the window portion 14c and the left end of the front frame 14 when viewed from the front of the pachinko machine 10 (the left-right width of the so-called left side frame portion: shown on the right side in FIG. 11 (a)), 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 14 itself. In the state where the front frame 14 is closed, the frame width on the opening / closing axis side is set wide so that the left end portion of the outer rail 62 is covered and hidden by the frame portion on the left side of the front frame base 200. For this reason, the outer rail 62 is overlapped with the left side frame portion of the front frame 14 when viewed from the front of the pachinko machine 10, and it is difficult to visually recognize the game ball in front of the entrance of the game area. Here, since the player visually recognizes the game balls showing various behaviors in the game area and enjoys the ball game, even if it is difficult to visually recognize the game ball before entering the game area, there is nothing in the actual game. There will be no hindrance. Therefore, sufficient strength and support strength of the front frame 14 can be ensured without hindering the game. Incidentally, the distance in the left-right direction between the left end position of the outer rail 62 and the left end position of the outer frame 12 when viewed from the front of the pachinko machine 10 is about 30 mm, the right end position of the game area (the inner right end position of the arc member 70) and the outer frame. The distance in the left-right direction with respect to the right end position of 12 is about 45 mm.

  In addition, the front frame 14 is provided with light emitting means such as various lamps around the periphery (for example, a corner portion). These light-emitting means play a role of enhancing the effect of the game during the game by changing or controlling the light-emitting mode by turning on or flashing according to the change in the gaming state at the time of big hit or predetermined reach. As shown in FIG. 1, on the upper side of the window portion 14c and on both the left and right sides thereof, there are provided electric decoration portions 202 to 204 having built-in light emitting means such as LEDs along the periphery of the window portion 14c. In the pachinko machine 10, these illumination parts 202 to 204 function as effect lamps such as jackpot lamps, and each of the illumination parts 202 to 204 is turned on by lighting or blinking of the built-in LEDs at the time of jackpot or reach effect. Alternatively, it blinks to notify that the jackpot is being hit or that the reach is one step before the jackpot.

  Further, as shown in FIG. 1, a prize ball lamp 205 that is turned on while awarding a prize ball is provided in the upper right part of the front frame 14 as viewed from the front. An error display lamp 206 that is turned on when an error occurs is provided. In addition, a small window 207 is formed on the lower side of the right illumination part 204 by attaching a transparent resin from the back side of the front frame base 200 so that the back side of the front frame 14 can be seen. A stamp or the like affixed to the affixing space K1 (see FIG. 3) is visible from the front surface of the pachinko machine 10. In addition, in the pachinko machine 10, a plated member 208 made of ABS resin that is chrome-plated is attached to an area around the electric decoration parts 202 to 204 in order to bring out more gorgeousness. For this chrome plating, trivalent chrome is used in consideration of the production environment and the like, instead of hexavalent chrome which has been widely used conventionally.

  As shown in FIG. 1, a lending operation unit 210 is disposed below the window 14c. The ball lending operation unit 210 is provided with a frequency display unit 211, a ball lending button 212, and a return button 213. When the lending operation unit 210 is operated in a state where a bill or a card is inserted into a card unit (ball lending unit) (not shown) arranged on the side of the pachinko machine 10, a game ball according to the operation Is lent out. Specifically, the frequency display unit 211 is an area in which remaining amount information such as a card is displayed, and a built-in LED is lit to display the remaining amount as a remaining amount information. The ball lending button 212 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 201 as long as there is a remaining amount on the card or the like. Is done. The return button 213 is operated when requesting the return of a card or the like inserted into the card unit. 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, does not require the ball lending operation unit 210. It is also possible to add a decorative seal or the like to the installation portion of the parts so that the component configuration is common. A pachinko machine using a card unit and a cash machine can be shared.

  In the upper right corner on the back side of the front frame 14, as shown in FIG. 11A, a light emitting substrate 214 for LED as a light emitting means is attached to the back surface of the front frame base 200 with screws. In addition, various reinforcing members made of metal are provided on the back side of the front frame 14 so as to surround the window portion 14c. Specifically, metal reinforcing plates 221 to 224 are respectively attached to the back side of the front frame 14 and on the upper and lower and left and right outsides of the window portion 14c. These reinforcing plates 221 to 224 are connected in contact with each other to increase the rigidity and strength of the front frame 14 that has been reduced by the formation of the window portion 14c. Further, the right reinforcing plate 221 is disposed so as to overlap the back side of the light emitting substrate 214 described above, but in order to avoid direct contact between the two, or to prevent the light emitting substrate 214 from being energized. A transparent synthetic resin cover plate 215 is provided between the reinforcing plate 221 and the light emitting substrate 214. Even if a noise or a magnetic field is generated around the reinforcing plates 221 to 224 due to charging, the influence on the light emitting substrate 214 is reduced by the cover plate 215, and malfunctions and failures are suppressed. . A part of the reinforcing plates 221 to 224 is grounded (not shown) so that the reinforcing plates 221 to 224 are not easily charged.

  The reinforcing plate 221 on the right side of the back surface of the front frame 14 is provided with an engaging claw 221a (see FIG. 2) having a hook shape at an intermediate position. The engaging claw 221a is configured to enter a groove 30j formed in the inner frame 13 (inner frame base 30) with the front frame 14 closed. As shown in FIG. 5, a metal stop plate 39 is screwed to the inner frame base 30 so as to cover a part of the groove 30 j, and the front frame 14 is closed with respect to the inner frame 13. In this state, the tip of the engaging claw 221a enters the back side of the retaining plate 39 shown in FIG. Accordingly, the front frame 14 can be prevented from being lifted at an intermediate position on the left side when viewed from the front of the pachinko machine 10, the upper plate 201 is provided on the front frame 14, and the front frame 14 is configured to be large in the vertical direction. Even if the (positions of the support brackets 33 and 34) are largely separated from each other, an illegal act with the front frame 14 floating can be suppressed.

  On the reinforcing plate 222 on the left side of the rear surface of the front frame 14, a pair of upper and lower front frame flange portions 14 a that protrude from the rear surface side of the front frame 14 and are formed in a bowl shape are integrally formed. The front frame 14 is locked by engaging the front frame collar 14 a with the front frame collar 411 of the locking unit 410 provided on the back side of the inner frame 13. The front frame 14 in the locked state is unlocked by performing a predetermined unlocking operation on the cylinder lock 420 with a dedicated key, and is in a state where it can be opened.

  A screw hole through which the screw 225 is inserted is provided in a central portion in the left-right direction of the reinforcing plate 223 on the upper back side of the front frame 14, and a tip portion of the screw 225 is formed as shown in FIG. It is screwed to a plating member 208 provided on the front side of the front frame 14, and the plating member 208 is grounded through a screw 225 and a reinforcing plate 223. Therefore, even if the decorative plating is applied to the front side of the front frame 14, problems due to charging and noise caused by the charging can be suppressed.

  As shown in FIG. 2, a resin-made rail side wall member 226 is provided on the reinforcing plate 224 below the back surface of the front frame 14 at a position facing the firing rail 93. The rail side wall member 226 serves as a side wall of the launch rail 93 when the front frame 14 is closed, and functions so that game balls do not spill from the launch rail 93. Further, on the right side of the rail side wall member 226, a ball passage rod 241 that protrudes from the back surface side of the front frame 14 so as to be continuous with the hole connected to the upper plate 201 is fixed to the front frame base 200 with a screw. When the front frame 14 is closed, the ball passage rod 241 pushes the shutter 37 (see FIG. 2) on the inner frame 13 side to form a game ball flow path to the upper plate 201.

  On the back side of the front frame 14, on the left side of the rail side wall member 226, as shown in FIG. An opening / closing unit 230 is provided on the upper side of the ball outlet 224a. The opening / closing unit 230 closes the ball outlet 224a when the front frame 14 is opened. The ball outlet 224a is provided in the most downstream portion of the upper plate 201, and communicates the upper plate 201 and the introduction port 102b (see FIG. 7) of the ball launch unit 90 when the front frame 14 is closed. The game ball placed on the upper plate 201 is guided to the introduction port 102b of the ball launching unit 90 via the ball outlet 224a.

  Here, the structure of the opening / closing unit 230 will be described with reference to FIG. The opening / closing unit 230 includes a housing 231 as a case member screwed to the lower reinforcing plate 224, and an upper end accommodated in the housing 231 and a lower portion extending along the lower reinforcing plate 224. A thin plate-shaped shielding plate 232 that extends and a rotation lever 233 made of a hard resin that is rotatably fixed to the inner surface of the housing 231 while the upper end of the shielding plate 232 is wound and fixed. ing. The opening / closing unit 230 is integrated with the housing 231 by assembling the shielding plate 232 and the rotation lever 233, and the assembling work on the front frame 14 side is facilitated and simplified.

  The rotation lever 233 is pivotally supported by the housing 231 about a rotation shaft 231a provided on the inner surface of the housing 231 so as to be substantially parallel and substantially horizontal to the lower reinforcing plate 224. The rotation lever 233 includes a plate support portion 233a extending from the rotation shaft 231a toward the reinforcing plate 224 (left side in FIG. 12A), and extending downward from the rotation shaft 231a. In addition, a contact portion 233b that protrudes out of the housing 231 is provided so as to abut a part of the inner frame 13 when the front frame 14 is closed. The inner frame base 30 is provided with a protrusion 30k (see FIG. 5) that protrudes from the attachment surface 30f to the front surface, and the contact portion 233b is provided so as to contact the protrusion 30k. Since the contact portion 233b extends in a direction substantially perpendicular to the opening / closing direction of the front frame 14 (the left-right direction in FIG. 12A) with respect to the rotation shaft 231a, the contact portion is closed when the front frame 14 is closed. When the 233b is pressed by the inner frame 13, the rotation lever 233 is easy to rotate, and the operation over a long period of time is ensured.

  The shielding plate 232 is formed of an elastic thin plate-like metal piece (for example, a stainless steel thin plate), and one end is fixed to the plate support portion 233a (the end portion on the front frame 14 side) of the rotating lever 233, The lower end 232a which is the other end is a free end. The lower end 232a of the shielding plate 232 is formed wider than the ball outlet 224a as shown in FIG. Therefore, the ball outlet 224a is reliably covered by the lower end portion 232a of the shielding plate 232 so that the elastic deformation in the middle portion of the shielding plate 232 is facilitated and the operation resistance is lowered, so that the game ball flows out of the ball outlet 224a. The shielding plate 232 can surely prevent it. Note that the width of the lower end 232a may be narrower than the ball outlet 224a, but it is preferable to set the width to be equal to or greater than the same in order to prevent an erroneous outflow of the game ball, and the lower end of the shielding plate 232 from the ball outlet 224a. It is preferable to widen the width of 232a.

  If the lower end 232a of the shielding plate 232 is narrower than the ball outlet 224a, the shielding plate 232 enters the ball outlet 224a, the lower end of the shielding plate 232 collides with the game ball in the ball outlet 224a, and the shielding plate 232 is deformed. And damage is likely to occur. In the pachinko machine 10, the lower end portion 232a of the shielding plate 232 is wider than the ball outlet 224a. Deformation and damage are prevented.

  Here, on the lower side of the ball outlet 224a, as shown in FIG. 12 (a), a passage leading from the upper plate 201 to the lower plate 301 and a closing plate 234 for closing the passage are provided. 234 is movable to the front side of the pachinko machine 10 (left side in FIG. 12A). When the closing plate 234 moves to the front side, the upper plate 201 and the lower plate 301 communicate with each other, and the game ball flows down to the lower plate 301. In this case, if the lower end portion 232a of the shielding plate 232 is narrower than the bulb outlet 224a, the lower end portion 232a may enter the bulb outlet 224a to cause clogging. By forming the lower end 232a of the shielding plate 232 wider than the bulb outlet 224a, the communication between the upper plate 201 and the lower plate 301 can be ensured, and the occurrence of clogging of the bulb can be suppressed.

  The shielding plate 232 of the opening / closing unit 230 is supported by the reinforcing plate 224 and the plate support portion 233a of the rotating lever 233 in a state where a flat thin plate is elastically deformed and bent downward. For this reason, the shielding plate 232 is in a state of pressing the reinforcing plate 224 so as to return to the original flat state by the elastic force. When the front frame 14f is in the open state (the state shown in FIG. 12A), the ball outlet 224a is closed while being pressed by the shielding plate 232, and the game ball is prevented from flowing out.

  When the front frame 14f is in the open state, as shown in FIG. 12A, the front end side (lower end side) of the contact portion 233b of the turning lever 233 faces the back side of the front frame 14 (right side in FIG. 12A). Projecting. In this state, the rotation lever 233 is such that the contact portion 233b protrudes to the back side of the front frame 14 with the rotation shaft 231a as the center (FIG. 12 (FIG. 12). a) (counterclockwise direction), and stops at a position (first rotation position) in contact with a part of the housing 231 (stopper portion 231b).

  In the state in which the rotation lever 233 is disposed at the first rotation position, the shielding plate 232 is in a state of hanging down to a position where the lower end portion 232a closes the upper portion of the bulb outlet 224a. In this state, the flow of the game balls in the upper plate 201 is restricted by the shielding plate 232, and the game balls do not flow out from the ball outlet 224 a to the back side of the front frame 14. Therefore, even if the front frame 14 is opened while the game balls are stored in the upper plate 201, the game balls in the upper plate 201 can be prevented from flowing out by the shielding plate 232.

  Further, the housing 231 is provided with a pressing portion 231c that abuts against a portion between one end portion and the lower end portion 232a of the shielding plate 232 supported by the rotation lever 233 and presses the shielding plate 232 toward the reinforcing plate 224. It has been. For this reason, the shielding plate 232 is more strongly pressed toward the reinforcing plate 224, so that the game ball is guided to the ball outlet 224a vigorously, or there are a lot of game balls in the upper plate 201 so that the shielding plate 232 is opened. Even when the force increases, the game ball is more reliably received and the outflow of the game ball from the ball outlet 224a is surely prevented.

  When the front frame 14 is closed from the state shown in FIG. 12A, as shown in FIG. 12B, the contact portion 233b of the rotating lever 233 is pressed while being in contact with the protrusion 30k of the inner frame 13. To the front frame 14 side. Thereafter, as the front frame 14 is closed, the pivot lever 233 pivots in the direction entering the housing 231 from the first pivot position shown in FIG. 12A (clockwise direction in FIG. 12B). When the front frame 14 is completely closed (that is, the front frame collar portion 14a is engaged with the front frame collar member 412 of the locking unit 410), the position is pushed into the housing 231 to the maximum (second position). ). As the rotation lever 233 rotates, the plate support portion 233a of the rotation lever 233 moves to the side (upper side) away from the ball outlet 224a.

  In the state where the rotation lever 233 is disposed at the second rotation position, the shielding plate 232 is further distorted along the plate surface of the reinforcing plate 224 while being further distorted by the rise of the plate support portion 233a of the rotation lever 233. Slide upward. The lower end 232a of the shielding plate 232 that has covered the ball outlet 224a rises to a position where the game ball can pass through the ball outlet 224a. When there is a game ball in the upper plate 201, the game ball sequentially flows out from the ball outlet 224a toward the introduction port 102b of the ball launch unit 90. Therefore, as long as the game balls are continuously supplied to the upper plate 201, the game balls can be continuously fired toward the game area by the ball launch unit 90.

  When the front frame 14 is released from the closed state, the rotation lever 233 (contact portion 233b) is released from the pressing by the protrusion 30k of the inner frame 13, and is restored from the second rotation position by the restoring force of the shielding plate 232. It is displaced to the 1 rotational position. With the displacement of the turning lever 233, the shielding plate 232 slides down on the plate surface of the reinforcing plate 224, the ball outlet 224a is closed at the lower end 232a of the shielding plate 232, and the game ball from the ball outlet 224a Is prevented from flowing out. That is, since the ball outlet 224a is closed along with the opening of the front frame 14, the store clerk at the game hall is worried about the outflow of the game ball in the upper plate 201 when the front frame 14 is opened and the work such as inspection is performed. The front frame 14 can be easily opened without any problems.

  Next, the glass unit 17 attached to the back surface of the front frame 14 will be described with reference to FIGS. FIG. 13 is a front view of the glass unit 17. 14 is a cross-sectional view taken along line Sa-Sa in FIG. 13, FIG. 15 is a cross-sectional view taken along line Sb-Sb in FIG. 13, and FIG. 16 is a cross-sectional view taken along line Sc-Sc in FIG. It is. FIG. 17 is a partially enlarged view of the glass unit 17 as seen from the direction of arrow V in FIG.

  The glass unit 17 in the present embodiment is not formed by attaching rectangular plate glasses to the front frame separately in front and rear pairs as in the prior art, but as a whole, two plate glasses 151 having a round shape are integrated (assembled). And then attached to the front frame 14. The glass unit 17 substantially corresponds to the shape of the window portion 14c (see FIG. 1) of the front frame 14, and is provided so as to surround a pair of front and rear plate glasses 151 that are substantially circular and have the same shape, and the periphery of the plate glasses 151. The holding frame 153 is provided.

  The holding frame 153 is made of ABS resin, and is formed in an annular shape along the outer shape of the plate glass 151 with a substantially “h” -shaped cross section as shown in FIG. For this reason, on both sides of the holding frame 153 (upper and lower sides in FIG. 14), a holding portion for the plate glass 151 formed in a pair of bowl-shaped cross sections is formed, and the outer periphery of each plate glass 151 is surrounded by the holding frame 153. The outer peripheral edge on the one surface side is disposed in contact with the holding frame 153. The holding frame 153 and the plate glass 151 are respectively bonded and fixed by an adhesive (bonded with a hot-melt adhesive or the like), and the two plate glasses 151 are integrated with a predetermined interval by a holding frame 153 interposed therebetween. It becomes.

  As shown in FIG. 13, the holding frame 153 is formed in a shape that bulges outward on one side (lower left side in FIG. 13), and a part of the plate glass 151 also bulges so as to cover the bulged portion. The shape is out. This bulging portion serves as a cover that covers a part of the guide rail (the lower left portion in FIG. 3) formed by the outer rail 62 and the inner rail 61 on the surface of the game board 16, and the front surface of the game board 16 in the guide rail portion. The outflow of game balls to the side is regulated.

  In addition, the holding frame 153 is provided with a partition wall 153a that divides an area between the two glass sheets 151 in a portion that bulges outward on one side (lower left side in FIG. 13). A storage portion 154 is formed between the two plate glasses 151 by the partition wall 153 a, and a drying tool 155 that absorbs moisture is provided in the storage portion 154 to prevent moisture condensation and fogging. The drying tool 155 includes a casing that forms a storage space inside with a pair of two case members facing each other, and a desiccant on the grains that are housed in the casing. The casing is partitioned into a plurality of rooms by partition walls (not shown), and a desiccant is accommodated in each room. Examples of the desiccant include zeolite and silica gel. The casing is formed with a large number of small holes that communicate with the inside and outside of the casing, and the air in the space sealed or nearly sealed by the two glass plates 151 is efficiently dehumidified, thereby preventing the occurrence of condensation. It has become so. The partition wall 153a and the drying tool 155 of the holding frame 153 are arranged on the outer peripheral side of the opening formed by the window portion 14c of the front frame 14, and the drying tool 155 and the like unnecessary for decoration of the pachinko machine 10 are externally provided. Is not visible.

  As shown in FIG. 15, the holding frame 153 is provided with an escape hole 153 b that communicates the internal space surrounded by the two plate glasses 151 and the holding frame 153 with the outside. This escape hole 153b is provided in order to make the bonding and fixing of the plate glass 151 easy and reliable. Adhesive is injected into the entrance of the escape hole 153b, dried and hardened. Further, the inner surface of the escape hole 153b is formed in a tapered shape (conical shape) in which the inner diameter gradually decreases from the outside (the lower side in FIG. 13) to the inside of the holding frame 153, and when the adhesive is injected from the outside. The escape hole 153b is easily blocked.

  Here, the assembling process of the glass unit 17 will be described with a focus on the portion where the two glass plates 151 are bonded and fixed to the holding frame 153 in particular. One plate glass 151 is placed, and the holding frame 153 is bonded and fixed to the plate glass 151. Next, after the drying tool 155 is set in the housing portion 154, the second sheet glass 151 is bonded and fixed to the holding frame 153.

  The second sheet glass 151 is pressed with a strong force in order to make the bonding more reliable. However, the air between the two sheet glasses 151 may be compressed during the pressing. If the air is strongly compressed, there is a concern that the plate glass 151 may be peeled off from the holding frame 153 after bonding due to the expansion of the air. In this respect, in the present embodiment, since air can enter and exit between the glass plates 151 and the outside through the escape holes 153b, the air is compressed even if the second glass plate 151 is pressed during adhesion fixing. Thus, a situation in which the plate glass 151 peels from the holding frame 153 due to the expansion of air does not occur.

  After the two plate glasses 151 are bonded to the holding frame 153, an adhesive is injected into the escape hole 153b, and is dried and cured after a while. As a result, a sealed space is formed between the glass plates 151, and the intrusion of moisture, dust, etc. is restricted, and the hygroscopic effect by the drying tool 155 is enhanced to improve the visibility of the game area. it can.

  The holding frame 153 is provided with mounting portions 153c that protrude outward at a plurality of locations on the periphery thereof. Each attachment portion 153c is formed in the same shape, and each attachment portion 153c is provided with an insertion hole 153d along the surface direction of the plate glass 151 as shown in FIG. Further, a metal plate 161 as a thin washer having a small-diameter hole 161a at a position corresponding to the insertion hole 153d is held on one surface (the upper surface in FIG. 16) of the attachment portion 153c by a small screw 162. It is fixed to the frame 153. Further, an attachment screw 163 for attaching the glass unit 17 to the front frame 14 is provided so as to be inserted through the insertion hole 153 d and the small diameter hole 161 a of the metal plate 161.

It is formed by the operation part 163c provided in this. The shaft portion 163a is formed to have a smaller diameter than the small diameter hole 161a of the metal plate 161, while the operation portion 163c is formed to be larger. The male screw portion 163b has substantially the same outer diameter as the small-diameter hole 161a of the metal plate 161, and has an outer diameter larger than that of the small-diameter hole 161a and a smaller valley diameter. For this reason, the mounting screw 163 can be mounted by screwing the male screw portion 163b into the small diameter hole 161a of the metal plate 161, and can be moved through the length of the shaft portion 163a (stroke amount) through the metal plate 161. Thus, the holding frame 153 cannot be removed.

  As shown in FIG. 17, the operation portion 163c of the mounting screw 163 is formed in a cylindrical shape having a diameter larger than that of the shaft portion 163a, and its outer peripheral surface is processed to be jagged by a fine groove 163c2 extending in the axial direction. In addition, a cross-shaped groove 163c1 is provided at the center of the end surface of the operation portion 163c, and the mounting screw 163 can be rotated by a tool such as a Phillips screwdriver. For this reason, even if the outer peripheral surface of the operation part 163c is pinched with a fingertip, even if a predetermined tool is inserted into the cross-shaped groove 163c1, the attaching screw 163 can be rotated. Therefore, the attachment / detachment operation of the glass unit 17 can be performed without a tool, and can be performed more easily and reliably when there is a tool. The mounting screw 163 is configured to be screwed into the metal plate 161 so that it cannot be removed from the holding frame 153. May be easily removable. Further, a locking washer such as a spring washer may be provided between the mounting screw 163 (operation unit 163c) and the metal plate 162. Further, the outer diameter shape of the operation portion 163c is not limited to the above-described shape, and may be formed so as to be easily rotated by hand, for example, a so-called thumb screw having portions projecting in a plate shape on both sides of the shaft. good.

  On the back side of the front frame 14, as shown in FIG. 11A, there are provided attachments 227 in which female screws are formed at a plurality of locations corresponding to attachment portions 153 c provided on the glass unit 17. The attachment 227 is a metal member that is formed in a boss (cylindrical) shape and has an internal thread on which an attachment screw 163 can be screwed, and is screwed or press-fitted into a predetermined position of the front frame base 200. Each is fixed. The glass unit 17 is attached and fixed to the rear surface of the front frame 14 by fixing the attachment portions 153 c to the attachments 227 by the attachment screws 163.

  Further, on the back side of the front frame 14, as shown in FIG. 2, three ribs 200 a to 200 c that protrude to the back side along a part of the outer peripheral shape of the holding frame 153 are integrally formed with the front frame base 200. Has been. The lower ribs 200b and 200c are provided so as to protrude larger than the upper rib 200a at the two lower portions of the window portion 14c of the front frame base 200. When the glass unit 17 is attached, the lower ribs 200b and 200c are attached to support the lower side. To assist. The upper rib 200a and the lower rib 200c are integrally formed with a locking projection that protrudes toward the center of the window portion 14c at the leading end of each rib in the protruding direction. At the time of attachment, the glass projection 17 can be temporarily fixed by fitting the engaging protrusion into a recess provided on the outer peripheral edge of the holding frame 153.

  Next, returning to FIG. 11A, the configuration of the front frame 14 will be described. Support metal fittings 228 and 229 are attached at two upper and lower positions as a support mechanism of the inner frame 13 on the right side end portion of the rear surface of the front frame 14 (left end portion in front view of the pachinko machine 10). The front frame 14 is releasably attached to the inner frame 13 by assembling the support brackets 228 and 229 on the front frame 14 side to the support brackets 33 and 34 (see FIG. 5) on the inner frame 13 side.

  More specifically, the support bracket 228 on the upper side of the front frame 14 has a substantially rod shape, and is formed in a stepped columnar shape whose upper diameter is thicker than the lower diameter. As described above, the support bracket 33 on the upper side of the inner frame 13 is provided with the support hole 33a having a notch opened on the front side of the inner frame 13, and the width of the notch of the support hole 33a is set to the front frame. 14 is narrower than the upper diameter of the upper support fitting 228 and wider than the lower diameter. Therefore, when the lower portion (small diameter portion) of the upper support fitting 228 is fitted into the support hole 33a and then the support fitting 228 is slid downward, the large diameter portion of the support fitting 228 is fitted into the support hole 33a. The support fitting 228 cannot be removed from the support hole 33a.

  The lower support bracket 229 on the lower side of the front frame 14 is fixed to the back side of the front frame 14 with screws, and is bent from the back side to the lower end surface. The support fitting 229 is provided with a support hole 229a that opens upward on the lower end surface of the front frame 14, and the support hole 229a has a protruding shaft formed by the support fitting 34 on the inner frame 13 side.

  As a procedure for mounting the front frame 14 to the inner frame 13, first, the lower portion (small diameter portion) of the support fitting 228 on the upper side of the front frame 14 is inserted into the support hole 33a through the notch. Next, the front frame 14 is slid downward after the support hole 229a on the lower side of the front frame 14 is positioned on the protruding shaft 34a of the support fitting 34 on the lower side of the inner frame 13. The support metal 228 on the upper side of the front frame 14 has a large-diameter portion fitted into the support hole 33a and cannot be removed. Installation is complete.

  Next, the lower plate unit 15 will be described with reference mainly to FIGS. 18 and 19. 18 is a front view of the lower plate unit 15, and FIG. 19 is a rear view thereof. The lower plate unit 15 is obtained by attaching a lower plate 301, an operation handle 310, and the like to an ABS resin lower plate base 300 formed in a horizontally long rectangular shape.

  As shown in FIG. 18, the lower tray unit 15 is provided with a lower tray 301 as a ball receiving tray at a substantially central portion, and is discharged from the lower tray discharge port 36a (see FIG. 2) on the inner frame 13 side through the discharge port 301a. The played game balls are configured to be stored in the lower plate 301. The lower plate 301 is formed by sticking a flame retardant ABS resin formed as a separate component to the lower plate base 300 to the surface. Although it is not necessary to form all of the lower plate 301 with flame-retardant ABS resin, at least the surface portion of the lower plate 301, that is, the surface layer of the lower plate 301 and the front panel 302 at the back of the lower plate 301 are made of ABS resin. It is preferable to form. Since there is a risk that the lit cigarette will be left on the lower plate 301, it is possible to prevent damage to the pachinko machine 10 and the occurrence of fire by forming at least its surface portion with flame retardant ABS resin. It is. The front panel 302 is provided with a number of speaker holes 303 for outputting sound from the speaker SP, and the speaker SP is screwed at a position corresponding to the speaker hole 303 on the back side of the lower plate unit 15. It is fixed by.

  In the lower part of the front of the lower plate 301, a ball removal lever 304 is provided for operation when the game balls stored in the lower plate 301 are discharged downward. The ball release lever 304 is always urged to the right, and by sliding it to the left against the urge, the bottom opening formed on the bottom surface of the lower plate 301 opens, A game ball naturally falls from the bottom opening and is discharged. The operation of the ball pulling lever 304 is normally performed in a state where a box (generally referred to as “a thousand box”) for receiving the game balls discharged from the lower plate 301 is placed below the lower plate 301.

  As described above, the operation handle 310 is disposed on the right side of the lower plate 301, and the ashtray 305 is attached on the left side of the lower plate 301. The ashtray 305 is configured to be rotatable in the front and back directions together with a shaft that is rotatably attached to the lower tray base 300. A metal plate 306 is provided on the back surface side of the lower plate unit 15 so as to cover the entire back surface, and the rigidity and strength of the lower plate unit 15 itself are enhanced.

  The lower pan unit 15 is attached to the inner frame 13 so as to be openable and closable. Like the inner frame 13 and the front frame 14, the lower pan unit 15 can be opened to the front side with the left side when viewed from the front of the pachinko machine 10 as an opening / closing axis. Yes. The lower dish unit 15 is provided with a support hole 307 on the upper left side of the front view and a support shaft 308 on the lower left side of the front view. When the support hole 307 and the support shaft 308 of the lower plate unit 15 are assembled to the support brackets 34 and 35 (see FIG. 5) on the inner frame 13 side, the lower plate unit 15 is attached to the inner frame 13 so as to be opened and closed. Is done.

  The support hole 307 and the support shaft 308 will be described in more detail. The support hole 307 is configured by a hole drilled in a portion where the upper end portion of the sheet metal 306 is folded back, and protrudes downward in the support bracket 34 on the inner frame 13 side. The protruding shaft 34b to be inserted can be inserted. The support shaft 307 is composed of a substantially inverted L-shaped projection that can be projected and retracted in the vertical direction, and is always maintained in a state of projecting downward by a spring (not shown) covered by the sheet metal 306.

  As a mounting procedure for the lower plate unit 15, first, the protruding shaft 34 b on the inner frame 13 side is inserted into the support hole 307 to fix the upper side of the lower plate unit 15 to the inner frame 13. After that, the support shaft 308 is brought into an immersion state against the urging force of the spring, and then the tip of the support shaft 308 is aligned with the support hole of the support fitting 35 provided on the lower side of the inner frame 13. When the positions of the support shaft 308 and the support hole match, the support shaft 308 is fitted into the support hole by the biasing force of the spring, and the mounting of the lower dish unit 15 is completed.

  The sheet metal 306 of the lower dish unit 15 is formed with a lower dish engaging portion 15a formed in a substantially rectangular shape and arranged in two upper and lower portions on the left side of the back surface. The lower plate unit 15 is locked by engaging the lower plate engaging portion 15 a with the lower plate hook member 413 of the locking unit 410 provided on the back side of the inner frame 13. The lower plate unit 15 in the locked state is unlocked by performing a predetermined unlocking operation with the dedicated key on the cylinder lock 420 and is in a state where it can be opened.

  Here, the lower plate 301 and the operation handle 310 of the pachinko machine 10 in which the lower plate unit 15 is arranged are conventionally formed as a part of the inner frame 13 and cannot be opened to the front side. 14 is configured so as to cover the front side of the inner frame 13 up to the lower end portion of the upper plate 201 formed by 14. On the front side of the inner frame 13 covered with the front frame 14, a game board 16 that forms a game area and a ball launch unit 90 that launches a game ball toward the game area are arranged side by side, When only the front frame 14 is opened forward and the lower plate 301 and the operation handle 310 are not opened, the arrangement position of the ball launching unit 90 is limited to the lower end portion of the upper plate 201, and the game is formed on the upper side. It was difficult to enlarge the area.

  In the pachinko machine 10 according to the present embodiment, since the lower plate unit 15 is configured to be openable to the inner frame 13 in addition to the front frame 14, the ball launch unit 90 is placed on the back side of the lower plate 301 and the operation handle 310. It can be arranged on the lower side so as to overlap, and accordingly, the game area of the game board 16 can be formed larger vertically. Moreover, since the lower plate unit 15 can be opened, in addition to the back surface side at the lower end portion of the inner frame 13, various types are provided on each surface of the lower surface portion of the lower plate unit 15 and the front surface side of the inner frame 13 at the lower end portion. Components and wiring can be accommodated, and the degree of freedom in designing the components and wiring is increased. Further, when working on the lower side of the lower plate 301 or the operation handle 310, for example, when the ball clogging in the passage connecting the upper plate 201 and the lower plate 301 is eliminated, or the rear side of the lower plate 301 is positioned. In the case of checking a full tank sensor for detecting a full tank state, the lower tray unit 15 is opened, and the inner frame 13 is fixed to the outer frame 12 so that each of the inner frames 13 can be viewed from the front side. Work can be done. When the inner frame 13 is opened, it is difficult to work because the inner frame 13 swings with respect to the outer frame 12, but the work performed on the inner frame 13 by opening the lower tray unit 15 is fixed by the inner frame 13. It is simple because it can be done in the state that has been done.

  Further, the inner frame 13, the front frame 14, and the lower plate unit 15 are formed by assembling other members to the respective members (the inner frame base 30, the front frame base 200, and the lower plate base 300) as a base. In the present embodiment, the base members 30, 200, 300 are all made of synthetic resin, specifically, ABS resin. By forming each of these base members 30, 200, and 300 with a synthetic resin, it is possible to cope with a more complicated shape by forming the base member with metal, and decorations are formed by forming characters, patterns, etc. on the front surface of the pachinko machine 10. While improving the performance, an attachment part or the like of the mating part is integrally formed on the back surface side to reduce the production cost. In addition, the ABS resin is generally inexpensive and has a good paste such as plating and is excellent in decorativeness. Therefore, it is easy to form a decoration subjected to surface treatment at a low cost on the front surface of the pachinko machine 10. Furthermore, the ABS resin has an advantage of high impact resistance, so that the player falls down and collides with the front surface of the pachinko machine 10, or a player who is dissatisfied with the game result strikes the front surface of the pachinko machine 10. Even so, the ABS resin is suitable as a material for the base members 30, 200, and 300 because the resin is less likely to be damaged and the player is injured.

  The base members 30, 200, 300 and the decorative plate 24 of the outer frame 13 are all formed of ABS resin, which is the same material. For this reason, when at least two members of the base members 30, 200, 300 and the decorative plate 24 are formed in the same color, the degree of fading or discoloration is equivalent due to deterioration over time. Therefore, it is possible to reduce the difference in chromaticity of the front surface of the pachinko machine 10 constituted by a plurality of members over a long period of time and maintain a good quality appearance. In particular, it is preferable that the base members 30, 200, 300 and the decorative plate 24 of the outer frame 13 are made of the same material up to the manufacturer and material grade in order to maintain a good quality appearance.

  Next, the configuration of the back side of the pachinko machine 10 will be described with reference to FIGS. FIG. 20 is a rear view of the pachinko machine 10, and FIG. 21 is a diagram schematically showing the configuration of the control board unit and the back pack unit on the back of the pachinko machine 10. 22 is a rear view showing a state in which the game board 16 is assembled to the inner frame 13, FIG. 23 is a perspective view of the inner frame 13 viewed from the rear, and FIG. 24 is a perspective view of the game board 16 viewed from the rear.

  Here, the back side structures of the inner frame 13 and the game board 16 will be described with reference to FIGS. As shown in FIG. 22, the game board 16 is installed in a square frame-shaped installation area surrounded by the inner frame base 30, and includes three locking fixtures 511 provided on the left and right sides of the inner frame 13, It is fixed so as not to drop off by a total of four locking fixtures 511 and 512 with a resin-made locking fixture 512 provided substantially at the lower center of the frame 13. The locking fixtures 511 and 512 can be manually rotated, and can be switched between a fixed position (lock position) and a fixed release position (unlock position). FIG. 22 shows a state where the locking fixtures 511 and 512 are in the locked position. The locking fixtures 511 at the three left and right sides of the game board 16 are configured by L-shaped metal fittings formed by bending metal pieces so that the game board 16 does not protrude outward from the inner frame 13 in a state where the game board 16 is fixed. ing. The locking fixture 512 at one lower portion of the game board 16 is formed of a resin I-shaped fastener.

  A variable display device unit 80 is disposed in the center of the back surface of the game board 16. The variable display device unit 80 is provided with a frame cover 513 made of resin (for example, made of ABS) that covers the center frame 86 (see FIG. 3) from behind, and is provided at the rear end of the frame cover 513. The first symbol display device 81 as a liquid crystal display device and the display control device 505 are detachably attached in a state where they are overlapped in the front-rear direction. In the frame cover 513, an LED control board for driving LEDs and the like built in the center frame 86 is disposed.

  A back frame set 515 is attached to the back surface of the game board 16 so as to surround the variable display device unit 80. The back frame set 515 is a thin resin-molded product (for example, made of ABS) provided so as to stick to the back surface of the game board 16, and a game ball collecting mechanism for collecting game balls won in various winning openings. Is formed. Specifically, below the back frame set 515, the above-described general winning opening 63, the first winning opening 64, and the discharge opening for discharging the winning balls to the variable winning device 65 (see FIG. 3) to the back side of the game board 16. And a collection passage 516 that gathers at one location on the downstream side is formed. A discharge passage board 517 made of resin (for example, made of polycarbonate resin) is attached below the game board 16, and the discharge passage board 517 is used to guide the discharge ball to the outside of the pachinko machine 10. A discharge passage 518 is formed. Therefore, as exemplified by the phantom line in FIG. 22, all the game balls won in the general winning opening 63 and the like are gathered through the collection passage 516 of the back frame set 515, and further, the discharge passage 518 of the discharge passage board 517 is formed. Through the pachinko machine 10. In addition, the out port 66 (see FIG. 3) similarly leads to the discharge passage 518, 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 518.

  In the above configuration, with the lower end surface of the game board 16 as a boundary, a back frame set 515 (collection passage 516) is provided on the upper side, and a discharge passage board 517 (discharge passage 518) is provided on the lower side. The game board 16 is provided without overlapping (overlapping) in the front-rear direction. Therefore, when the game board 16 is removed from the inner frame 13, there is no inconvenience that the discharge passage board 517 prevents the game board 16 from being removed.

  Since the discharge passage board 517 is provided just behind the upper plate 201 on the front surface of the pachinko machine 10, a wire or the like is inserted from the ball discharge port (the upper plate discharge port 36b in FIG. 2) leading to the upper plate 201. Furthermore, an illegal act of causing the wire or the like to enter the game area side through a gap between the inner frame 13 and the discharge passage board 517 can be considered. Therefore, the discharge passage board 517 of the pachinko machine 10 is provided with a plate 519 extending in front of the pachinko machine 10 so as to almost integrally overlap the inner frame 13 around the back side of the upper plate 201. Therefore, even if a wire or the like tries to enter from the gap between the inner frame 13 and the discharge passage board 517, the wire or the like is obstructed by the plate 519, and it becomes very difficult for the wire or the like to enter the game area. As a result, an illegal act such as forcibly opening the variable winning device 65 (large opening) with a wire or the like can be prevented.

  In addition, on the back surface of the game board 16, a winning detection mechanism for detecting the entrance (passing) of a game ball to various winning openings is provided. Specifically, a prize opening switch 521 is provided at a position corresponding to the general prize opening 63 on the front side of the game board 16, and a specific area switch 522 and a count switch 523 are provided in the variable prize winning device 65. The specific area switch 522 is a switch for determining that a game ball won in the variable winning device 65 in the big hit state has entered a specific area (an area for determining whether or not to continue the big hit state), and the count switch 523 It is a switch to count. A first entrance switch 524 is provided at a position corresponding to the first entrance 64 and a second entrance switch 525 is provided at a position corresponding to the second entrance 67.

  The prize opening switch 521 and the second ball opening switch 525 are connected to the board relay board 526 via electric wiring (including a cable connector) (not shown), and the board relay board 526 is a main board (main controller) to be described later. 561) via electrical wiring. Further, the specific area switch 522 and the count switch 523 are connected to the large opening relay board 527 via electric wiring, and this large opening relay board 527 is connected to the main board via electric wiring. On the other hand, the first entrance switch 524 is directly connected to the main board without going through the relay board.

  Although not shown in the drawings, the variable winning device 65 includes a large opening solenoid for opening the specific winning opening (large opening) 65a and a winning ball sorting plate solenoid for guiding the winning ball to a specific area.

Is arranged.

  When the front frame 14 is closed, the front frame flange portion 14a enters the insertion port 415a and also enters the locking port 412a. The lower end of the locking port 412a is disposed at a position that contacts the protruding portion at the tip of the front frame flange portion 14a, and the front frame flange member 412 is pushed down by the front frame flange portion 14a and slides downward. When the protruding portion at the front end of the front frame flange portion 14a completely enters the locking port 412a, the front frame flange member 412 rises and returns to the original position by the pulling force of the coil spring, and is caught by the front frame flange portion 14a. The front frame 14 is locked so as not to be opened. Further, the front frame collar member 412 moves downward as the sliding collar 417 slides downward. The sliding rod 417 slides downward in conjunction with the counterclockwise operation with the dedicated key with respect to the cylinder lock 420, and, like the inner frame 13, the front frame 13 is locked by operating the dedicated key. Is released.

  The interlocking mechanism between the cylinder lock 420 and the sliding rod 417 will be described. As shown in FIG. 38, the lock shaft of the cylinder lock 420 has two protrusions that enter the notch of the sliding rod 417 by the rotation operation. A cam plate 420a is attached. When the dedicated key is inserted in the key hole 421 of the cylinder lock 420 and rotates clockwise (clockwise in FIG. 36), the lower projection of the cam plate 420a enters the notch of the sliding rod 417. The sliding rod 417 is pushed upward. On the other hand, when the dedicated key is rotated counterclockwise (counterclockwise in FIG. 36) with the key inserted into the keyhole of the cylinder lock 420, the upper projection of the cam plate 420a enters the notch of the sliding rod 417. Then push down the sliding rod 417 downward. In this way, the inner frame collar member 411 and the front frame collar member 412 interlocked with the sliding collar 417 can be moved by freely sliding the single sliding collar 417 up and down by rotating the dedicated key. The locked state with respect to the inner frame 13 and the front frame 14 locked for each of the flange members 411 and 412 can be released by operating. Therefore, compared with the case where a plurality of sliding rods are respectively configured to be interlocked with the lock shaft of the cylinder lock, the component configuration is simplified, and the manufacturing cost can be reduced.

  A heel member (lower plate heel member) 413 that is slidably supported by the support plate 416 while being always pulled upward by a coil spring (not shown) is disposed below the heel base 414. The lower plate cage member 413 is for engaging the lower plate engaging portion 15a (see FIG. 19) provided in the lower plate unit 15 to lock the lower plate unit 15, and is located in the center along the vertical direction. The upper and lower two flanges 413a that protrude to the front side from the upper part and the lower part and further protrude from the front end part are hooked on the lower dish engaging part 15a to restrict the opening of the lower dish unit 15.

  At the upper end of the lower plate ridge member 413, an operation portion 413b formed so as to be protruded to the front side is provided, so that the lower plate ridge member 413 can be pushed downward with a fingertip or the like. ing. The operation unit 413b of the lower dish unit 15 is always disposed at a position covered by the front frame 14, and can be exposed and operated only when the front frame 14 is opened.

  When opening the lower tray unit 13 in the closed state, first, the front frame 14 is opened so that the operation portion 413b of the lower tray unit 15 can be operated. After that, when the operation unit 413b is pressed against the biasing force of the coil spring and the lower plate cage member 413 is moved downward, the lower plate engagement unit 15a provided on the lower plate unit 15 side and the lower plate cage member The engagement state of the 413 with the flange portion 413a is released, and an unlocked state in which the lower plate unit 15 can be opened simply by pulling it forward is possible.

  The payout launch control device 611 controls the launch of the ball launch unit 90 (the launch solenoid 92 and the electromagnet 104) according to the operation of the operation handle 310 by the player. The launch solenoid 92 and the electromagnet 104 have predetermined conditions. Driving is allowed when it is in place. Specifically, it corresponds to the amount of rotation of the operation handle 310 on the condition that the touch sensor detects that the player is touching the operation handle 310 and the firing stop switch for stopping the firing is not operated. Then, the launch solenoid 92 is excited, and the game ball is launched with a strength corresponding to the operation amount of the operation handle 310.

  The backup area 713a has a stack pointer, each register, I / O, etc. at the time of power interruption when the power supply from the outside is cut off due to the occurrence of a power failure or the like, and the drive voltage supplied to the main controller 561 is cut off. The area of the pachinko machine 10 is restored to the state before power-off based on the information in the backup area 713a when the power is turned on. Writing to the backup area 713a is executed when the power is shut off by the NMI interrupt process, and restoration of each value written to the backup area 713a is performed when the drive voltage is supplied to the payout / discharge control device 611 (FIG. 52). See). As with the MPU 701 of the main controller 561, the power failure signal SG1 is input to the NMI terminal of the MPU 711 from the power failure monitoring circuit 742 when the power is interrupted due to the occurrence of a power failure or the like. When input to the MPU 711, an NMI interrupt process as a power failure process is immediately executed.

  An input / output port 715 is connected to the MPU 711 of the payout / release control device 611 via a bus line 714 composed of an address bus and a data bus. A RAM erase switch circuit 743, a main controller 561, a payout motor 658a, a firing solenoid 92, an electromagnet 104, and the like are connected to the input / output port 715, respectively.

  The display control device 505 displays a variation display of the second symbol (ordinary symbol) on the second symbol display device (LED) 82 and a variation display of the first symbol (special symbol) on the first symbol display device (LCD) 81. It is something to control. The display control device 505 includes an MPU 721, a ROM (program ROM) 722, a work RAM 723, a video RAM 724, a character ROM 725, an image controller 726, an input port 727, two output ports 728 and 729, a bus line. 730 and 731. The output side of the main controller 561 is connected to the input side of the input port 727, and the MPU 721, ROM 722, work RAM 723, and image controller 726 are connected to the output side of the input port 727 and the output port via the bus line 729. 728 is connected.

Further, an output port 729 is connected to the image controller 726 via a bus line 731, and the first symbol display device 81 is connected to the output side of the output port 729.

  The MPU 721 of the display control device 505 controls the display contents of the first symbol display device 81 and the second symbol display device 82 based on the symbol display command transmitted from the main control device 561. The ROM 722 is a memory for storing various control programs and fixed value data executed by the MPU 721, and the work RAM 723 is for temporarily storing work data and flags used when the MPU 721 executes various programs.

It is displayed on the symbol display device 81.

  The power supply unit 612 includes a power supply unit 741 for supplying a drive voltage to each part of the pachinko machine 10, a power failure monitoring circuit 742 for monitoring the interruption of the power supply from the outside due to a power failure or the like, and a RAM erase switch having a RAM erase switch 623 A circuit 743. The power supply unit 741 supplies necessary voltages to the main control device 561, the payout / discharge control device 611, and the like through a drive voltage supply path (not shown). As its outline, the power supply unit 741 takes in a voltage of 24 volts AC supplied from the outside, and a voltage of 12 volts as a driving voltage for driving various switches, solenoids, motors, etc. or 5 volts for logic. , A backup voltage for RAM backup, and the like, and supply these 12 volt voltage, 5 volt voltage, and backup voltage to the main controller 561, the payout launch controller 611, and the like.

  The power failure monitoring circuit 742 is a circuit for outputting a power failure signal SG1 to each NMI terminal of the MPU 701 of the main controller 561 and the MPU 711 of the payout launch controller 611 when the power supply from the outside is interrupted due to the occurrence of a power failure or the like. The power failure monitoring circuit 742 monitors the voltage of DC stable 24 volts, which is the maximum voltage output from the power supply unit 741, and determines that a power failure (power shutdown) occurs when this voltage is less than 22 volts. Power failure signal SG1 is output to main controller 561 and payout launch controller 611. Based on the output of the power failure signal SG1, the main controller 561 and the payout launch controller 611 recognize the occurrence of the power failure and execute the NMI interrupt process. Note that the power supply unit 741 outputs a voltage of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the NMI interrupt processing even after the voltage of 24 VDC is less than 22 volts. Is maintained at a normal value. Therefore, main controller 561 and payout launch controller 611 can normally execute and complete the NMI interrupt process.

  The RAM erase switch circuit 743 is a circuit that outputs a RAM erase signal SG2 for clearing backup data to the main control device 561 and the payout / release control device 611 when the RAM erase switch 623 is pressed. When the RAM erase signal SG2 is input when the pachinko machine 10 is turned on, the main controller 561 and the payout launch controller 611 clear the data in the respective backup areas 703a and 713a.

  Next, the configuration of the main board removal detection circuit 706 will be described with reference to FIG. FIG. 40 is an electric circuit diagram schematically showing an electrical connection state between the main board removal detection circuit 706 and the power supply device 612. In particular, the main board removal detection circuit 706 shows the configuration of electronic components. In the power supply device 612, a power supply unit 741 is schematically shown to indicate the supply state of the drive voltage and the backup voltage.

  First, the power supply unit 741 of the power supply device 612 will be described. As described above, the power supply unit 741 generates a 5V drive voltage for logic. When the power switch 682a is operated to supply external power, the drive voltage supply switch 760 that is turned on in conjunction with the operation of the power switch 682a is turned on, and the drive voltage is charged in the backup power supply capacitor 761. . The drive voltage supply switch 760 includes two switches, a switch for supplying a drive voltage of 5 V to the drive voltage supply path Vcc and a switch for supplying a drive voltage for charging to the backup power supply capacitor 761. The switch is opened and closed at substantially the same timing. The drive voltage supply switch 760 may be a relay contact that is electrically conductive when the power switch 682a is turned on and the drive voltage is normally supplied.

  In a state where the drive voltage supply switch 760 is on, a drive voltage of 5 V is supplied to the drive voltage supply path Vcc and the backup voltage supply path Vbb, and the drive voltage is supplied to the main controller 561. On the other hand, in the state where the drive voltage supply switch 760 is turned off, the supply of voltage through the drive voltage supply path Vcc is cut off, but the backup voltage charged in the backup power supply capacitor 761 is mainly transmitted via the backup voltage supply path Vbb. It is supplied to the control device 561.

  Although the backup voltage is supplied to the backup power supply capacitor 761 by charging the drive voltage and discharging the charged voltage, for example, the backup voltage is supplied by connecting a lithium battery or other batteries. It is good as a thing.

  The drive voltage supply path Vcc is electrically connected to the power supply terminal Vcc of the MPU 701 and the OR circuit 763 of the main board removal detection circuit 706 to supply the drive voltage, and is connected to one end of the reset switch 559. The backup voltage supply path Vbb is connected to the backup area 703a of the RAM 703 and the power supply terminal Vbb of the flip-flop circuit 762, and supplies the backup voltage. The power supply device 612 is connected to the main control device 561 with a connector (not shown), and each voltage is supplied from the power supply device 612 to the main control device 561 via the connector. When the main controller 561 is detached from the pachinko machine 10, it is necessary to disconnect the connector, so that the supply of each voltage to the main controller 561 is cut off.

  Next, the configuration of the main board removal detection circuit 706 will be described. The main board removal detection circuit 706 mainly includes a flip-flop circuit 762 and an OR circuit 763. The flip-flop circuit 762 is a known D-type flip-flop, and has a D terminal to which an input signal is input, a CK terminal to which a clock signal is input, a Q1 terminal and a Q2 terminal as output terminals, and a backup voltage. It consists of a supplied Vbb terminal and a GND terminal connected to the ground. The OR circuit 763 includes an A terminal and a B terminal to which an input signal is input, a Y terminal that outputs when an input signal is input to either the A terminal or the B terminal, and a Vcc to which a drive voltage is supplied. The terminal and a GND terminal connected to the ground. Note that the flip-flop circuit 762 and the OR circuit 763 are known electronic components, and thus detailed description thereof is omitted.

  Here, electrical connection between the flip-flop circuit 762 and the OR circuit 763 will be described. The CK terminal of the flip-flop circuit 762 is directly connected to the MPU 701. The signal input to the CK terminal is a clock signal that is transmitted after the initial setting and the payout permission command are transmitted (S101, S102) in the main process (see FIG. 44) performed in the main controller 561 described later. SG3, and its clock signal SG3 is a one-pulse signal that maintains the H level for a predetermined time. Since the clock signal SG3 is transmitted when a driving voltage is supplied, it is also a signal for confirming power-on. When the clock signal SG3 is input to the CK terminal, the flip-flop circuit 762 outputs a signal corresponding to the input of the D terminal from the Q1 terminal and the Q2 terminal.

  For example, when the clock signal SG3 is input to the CK terminal in a state where an input signal of 5V (H level) is input to the D terminal, output is made from the Q1 terminal and output is not made from the Q2 terminal. That is, the Q1 terminal becomes H level and the Q2 terminal becomes L level. Further, when the clock signal SG3 is input to the CK terminal in a state where there is no input to the D terminal (L level), no output is made from the Q1 terminal and an output is made from the Q2 terminal. That is, the Q1 terminal becomes L level and the Q2 terminal becomes H level.

  The Q2 terminal of the flip-flop circuit 762 is connected to the input / output port 705 and outputs a main board removal signal SG4 for notifying the display control device 505 that the main control device 561 has been removed. Upon confirming the input of the main board removal signal SG4, the display control device 505 instructs the audio lamp control device 562 to notify and causes the error display lamp 206 (see FIG. 1) to display an error. Moreover, it is good also as what alert | reports by the other electrical decoration parts 202-204 and a speaker, and it is good also as what alert | reports that the main control apparatus 561 was removed by the 1st symbol display apparatus 81. FIG. Further, the main board removal signal SG4 may be input to the MPU 701. In this case, each process performed in the main controller 561 is stopped or each process performed in the main controller 561 is stopped. It is good to do.

  The other terminal of the reset switch 559 is connected to the A terminal of the OR circuit 763, and when the reset switch 559 is operated, an input signal is input to the A terminal. The Q terminal of the flip-flop circuit 762 is connected to the B terminal of the OR circuit 763. The Y terminal of the OR circuit 763 is connected to the D terminal of the flip-flop circuit 762. The OR circuit 763 outputs from the Y terminal while a signal is input to at least one of the A terminal and the B terminal. Therefore, when the reset switch 559 is operated and from the Q1 terminal of the flip-flop circuit 762, the OR circuit 763 is at the H level. When output is performed, an H level signal is output from the Y terminal. When output is performed from the Q1 terminal of the flip-flop circuit 762, the output from the Q1 terminal is input to the D terminal via the OR circuit 763. Therefore, if the H level output is made from the Q1 terminal while the backup voltage is supplied, the flip-flop circuit 762 can maintain the H level signal to the D terminal until the backup voltage is cut off. it can.

  Although the electrical connection between the flip-flop circuit 762 and the OR circuit 763 has been described above, the prevention means for preventing the circuits 762 and 763 from being damaged and the signals input to the circuits 762 and 763 are stabilized. Stabilization means (for example, a configuration in which a resistor is inserted in front of the input terminal so that an optimum voltage is input to the circuit, or a current is connected to the ground through a resistor before the input terminal. Since the configuration is a known technique, its description and illustration are omitted.

  Next, the operation of the main board removal detection circuit 706 will be described with reference to FIG. FIG. 57 is a diagram showing the state of the input signal or output signal of each electronic component and the notification state of the error display lamp 206 corresponding to the state. The input signal and the output signal are indicated as “H” when the signal is inputted and outputted, and “L” when the signal is not inputted and outputted, and the error display lamp 206 is notified. The state where the notification is made is represented as “ON”, and the state where the notification is not performed is represented as “OFF”.

  When power is supplied to the main control board 561 and a drive voltage is supplied from the power supply device 612, the drive voltage is supplied to each electronic component. In the initial state of the flip-flop circuit 762, the input to the D terminal is L level, the output from the Q2 terminal is H level, and the output from the Q1 terminal is L level. Therefore, even if the driving voltage is supplied to the main controller 561 and the clock signal SG3 is input to the CK terminal of the flip-flop circuit 762, the input to the D terminal of the flip-flop circuit 762 is at the L level. The output state of the Q2 terminal does not change. Therefore, the main board removal signal SG4 is output from the Q2 terminal, and notification is given by the error display lamp 206 (see FIG. 1).

  When the pachinko machine 10 is installed in a pachinko hall, an external power supply is turned on while operating the reset switch 559, whereby an input is made to the A terminal of the OR circuit 763, and the H level from the Y terminal of the OR circuit 763 Is output. The output from the Y terminal of the OR circuit 763 is input to the D terminal of the flip-flop circuit 762, and the D terminal becomes H level.

  When the clock signal SG3 is input to the CK terminal of the flip-flop circuit 706 in this state (the reset switch 559 is operated), an H level signal is output from the Q1 terminal of the flip-flop circuit 762, and the OR circuit An input is made to the B terminal of 763. Since the OR circuit 763 outputs from the Y terminal when there is an input at either the A or B terminal, the input to the D terminal of the flip-flop circuit 762 is continued. Therefore, the flip-flop circuit 762 continuously outputs H level from the Q1 terminal and does not output from the Q2 terminal (L level). Therefore, since no output is made from the Q2 terminal of the flip-flop circuit 762, the error display lamp 206 is not notified (the state of the circled number 1 in FIG. 57). Even when the main control device 561 is removed due to repair of the pachinko machine 10 or the like, the notification by the error display lamp 206 can be canceled by turning on the external power while operating the reset switch 559.

  Here, a case where the main controller 561 (substrate box 563) is removed from the pachinko machine 10 will be described. As described above, when the main control board 561 is removed from the pachinko machine 10, the drive voltage supply path Vcc and the backup voltage supply path Vbb are disconnected by disconnecting the connector. The supplied backup voltage is cut off. Accordingly, the flip-flop circuit 762 is initialized, the input to the D terminal becomes L level, the output from the Q2 terminal becomes H level, and the output from the Q1 terminal becomes L level. After that, when an external power supply is turned on and a clock signal is input to the CK terminal of the flip-flop circuit 762, the D terminal of the flip-flop circuit 762 is at the L level, and thus the H level output is maintained from the Q2 terminal of the flip-flop circuit 762. Is done. As a result, notification by the error display lamp 206 is performed (the state of the circled number 2 in FIG. 57). Therefore, since the notification by the error display lamp 206 is performed, it can be easily confirmed that the main controller 561 has been removed.

  Note that when the output from the Q2 terminal of the flip-flop circuit 762 becomes L level by operating the reset switch 559, the Q2 terminal of the flip-flop circuit 762 is switched according to the timing of the clock signal SG3 input to the CK terminal. The main board removal signal SG4 may be output. Therefore, the audio control device 505 may provide a delay time for the control at the time of start-up, and may not perform notification by the error display lamp 206 even if the main board removal signal SG4 is input during the delay time.

  As described above, in the pachinko machine 10 according to the present embodiment, the backup voltage supplied to the flip-flop circuit 762 is supplied from a connector (not shown) mounted on the main board (main control device 561). Is done through. Therefore, when the backup voltage supplied to the flip-flop circuit 762 is cut off, the main control device 561 may be removed from the pachinko machine 10. When the main controller 561 is removed from the pachinko machine 10, the ROM 702 is replaced with an illegal ROM that generates a jackpot by a specific gaming method, or a device that illegally generates a jackpot is attached between the ROM 702 and the MPU 701. May have been. If the pachinko hall starts operation with the illegal ROM replaced or the illegal device attached, the illegal ROM and the illegal device generate an illegal jackpot, and the pachinko hall suffers a large loss. However, according to the present embodiment, by providing the main board removal detection circuit 706, when the main controller 561 is removed from the pachinko machine 10, the Q2 terminal of the flip-flop circuit 762 becomes H level and the main board removal is performed. Signal SG4 is output. When the voice control device 505 receives the main board removal signal SG4, the voice control device 505 notifies the error display lamp 206 so that the pachinko machine 10 from which the main control device 561 has been removed can be easily confirmed by checking the error display lamp 206. Can be confirmed. Therefore, it is possible to prevent the pachinko hall from receiving a loss.

  In addition, since a sealing unit 564 is provided in the board box 563, a trace is left in the event of fraud, so it can be confirmed that the fraud has been performed. Since hundreds of pachinko machines 10 are installed in the machine, it takes a lot of time and number of people to check all of the pachinko machines 10. However, according to the present embodiment, the pachinko machine 10 that may have been cheated can be limited, so it is only necessary to confirm the sealing unit 564 of the board box 563 of the pachinko machine 10 that has been notified. The confirmation operation of the sealing unit 563 becomes easy.

  The flip-flop circuit 762 outputs an H level from the Q1 terminal in a normal installation state (a state in which a backup voltage is supplied), and the backup voltage is cut off when the main controller 561 is removed. Based on this, the H level is output from the Q2 terminal. Therefore, when the supply of the backup voltage is cut off and the flip-flop circuit 762 is cleared, it is detected whether or not the main controller 561 has been removed, so that accurate detection can be performed.

  Here, with reference to FIG. 41 and FIG. 42, the 1st symbol displayed on the 1st symbol display apparatus 81 and the display content of the 1st symbol display apparatus 81 are demonstrated. FIG. 41 is a diagram individually showing the first symbol, FIG. 42 is a diagram for explaining a display screen of the first symbol display device 81, and FIG. FIG. 42B is a diagram schematically showing an actual display screen.

  The first symbol is composed of ten types of main symbols with numbers from “0” to “9” and one type of sub-pattern of petal shape formed smaller than this main symbol. As shown in FIG. 41 (a) to FIG. 41 (i), each main symbol is configured by attaching numbers “0” to “9” on a rear symbol made of a wooden box, of which an odd number ( In the main symbols with 1, 3, 5, 7, 9), large numbers are added almost to the front of the wooden box. On the other hand, the main symbols with even numbers (0, 2, 4, 6, 8) are attached to the front of the wooden box almost fully, and attached symbols imitating characters such as furoshiki and helmets are added. An even number on the lower right side of the attached symbol is small in green and added so as to be displayed on the front side of the attached symbol.

  Moreover, although mentioned later for details, in the pachinko machine 10 of this embodiment, it is comprised so that a big hit may generate | occur | produce when the same main symbol is prepared. In this case, the main symbol to which the odd number is added corresponds to a “high probability symbol”, and when the high probability symbols all come together and the jackpot is reached, the special winning state 65a is released a predetermined number of times over a predetermined time period. After that, it shifts to a high probability state. On the other hand, the main symbol to which an even number is added corresponds to a “low probability symbol”, and when the low probability symbols are all in a big win, the special game state is entered, but in such a case, the high probability state is not entered. . Here, the high probability state is a state in which the combination of the first symbol becomes a jackpot as a combination of the predetermined probability variation symbols, and the subsequent jackpot probability is increased as added value, that is, when so-called probability variation (probability change). Say. Further, the normal state (low probability state) refers to a time when the probability of hitting is not probable, and refers to a state where the probability of jackpot is normal, that is, a state where the probability of jackpot is lower than that during probability change.

  Next, the display screen of the first symbol display device 81 will be described. As shown in FIG. 42 (a), the display screen of the first symbol display device 81 is roughly divided into two in the vertical direction, and the lower 2/3 is the main display area Dm in which the first symbol is variably displayed. The upper third is a sub display area Ds for displaying a notice effect and a character.

  In the main display area Dm, three symbol rows Z1, Z2, and Z3 of left, middle, and right are displayed. In each of the symbol rows Z1 to Z3, the above-described first symbols are displayed in a prescribed order. That is, in each symbol row Z1 to Z3, main symbols are arranged in ascending or descending numerical order, and one sub symbol is arranged between each main symbol. For this reason, a total of 20 first symbols of 10 main symbols and 10 sub-symbols are set in each symbol row, and each symbol row Z1 to Z3 is scrolled from top to bottom with periodicity. The display is changed. In particular, the left symbol row Z1 is arranged so that the numbers of the main symbols appear in descending order, and the middle symbol row Z2 and the right symbol row Z3 are arranged so that the numbers of the main symbols appear in ascending order.

  In the main display area Dm, the first symbols are displayed in the upper, middle, and lower three rows for each symbol row Z1 to Z3. Accordingly, the first symbol display device 81 displays a total of nine first symbols of 3 rows × 3 columns. In the main display area Dm, five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5 are set. In each game, the variable display stops in the order of the left symbol row Z1 → the right symbol row Z3 → the middle symbol row Z2, and the combination of jackpot symbols on any active line at the time of the stop (in this embodiment, A jackpot moving image is displayed as a jackpot if the same combination of main symbols is arranged.

  The sub display area Ds is horizontally long above the main display area Dm, and is further equally divided into three notice areas Ds1 to Ds3 in the left-right direction. Here, the left and right notice areas Ds1, Ds3 are normally covered with a double-open opaque door that is electrically opened and closed by a solenoid, and sometimes the solenoid is excited and the door is opened to the front side. The display area is visible to the player. The center notice area Ds2 is a display area that is always visible without being covered by the door.

  On the actual display screen, as shown in FIG. 42B, a total of nine main symbols and sub-designs of the first symbol are displayed in the main display area Dm. In the sub display area Ds, the left and right doors are closed, and the left and right notice areas Ds1, Ds3 are covered and the display screen cannot be visually recognized. If either one of the left and right doors or both doors are opened during the variable display, a video is displayed in the left and right notice areas Ds1 and Ds3, and it is easy for the player to change to a big hit than usual. It is suggested. In the center notice area Ds2, a predetermined character (a boy with a bee in this embodiment) usually performs a predetermined action and sometimes performs a special action different from the predetermined action or another character appears. The announcement effect is performed by putting out. The display screen of the first symbol display device 81 is basically divided into upper and lower display areas Dm, Ds, but displays the first symbol, characters, etc. larger across the display areas Dm, Ds. A display effect can be performed.

  Next, the operation of the pachinko machine 10 configured as described above will be described. In the present embodiment, the MPU 701 in the main control device 561 uses various counter information during the game to perform jackpot lottery, setting the symbol display of the first symbol display device 81, and the like. Specifically, As shown in FIG. 43, when the jackpot random number counter C1 used for the jackpot lottery, the jackpot symbol counter C2 used for selection of the jackpot symbol of the first symbol display device 81, and the first symbol display device 81 fluctuate and change. Reach random number counter C3 used for reach lottery, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, variation type counters CS1, CS2 used for variation pattern selection of the first symbol display device 81, , Left, middle and right out symbol counters CL, CM, CR used to set each out symbol in the left, middle and right columns It is set to be there. The second symbol random number counter C4 is used for the lottery of the second symbol display device 82.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using the R register (refresh register) in the MPU 701, and as a result, the numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 703. The RAM 703 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). Each value of the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 is stored in accordance with the winning timing of the game ball.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is configured as a loop counter that is updated in the same range as the jackpot random number counter C1 (value = 0 to 676), and is updated once per timer interrupt and within the remaining time of normal processing. Will be updated repeatedly. The jackpot random number counter C1 is updated periodically (once every timer interruption in the present embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the first entrance 64. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot symbol counter C2 determines the symbol when the fluctuation of the first symbol display device 81 is stopped at the time of the jackpot. In the present embodiment, the first symbol display device 81 has five effective lines. Since 10 kinds of specific symbols (main symbols) are set, 50 (0 to 49) counter values are prepared. In other words, the jackpot symbol counter C2 is configured so that one by one is added in order within the range of 0 to 49, and after reaching the maximum value (that is, 49), it returns to 0. The jackpot symbol counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the first entrance 64.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the last stop symbol to stop after the reach has occurred by shifting the last stop symbol by only one before and after the reach symbol, and the last stop symbol after the reach has occurred. “Reach other than front / rear out” and stop “complete out” that does not occur reach. For example, the reach random number counter C3 = 0, 1 corresponds to the front / rear out of reach, the reach random number counter C3 = 2-21 corresponds to the reach other than the front / rear out, and the reach random number counter C3 = 22-238 corresponds to the complete out. The reach lottery may be set individually according to the state of the lottery probability of the first symbol display device 81, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 703 at the timing when the game ball wins the first entrance 64.

  Of the two variation type counters CS1 and CS2, one variation type counter CS1 is incremented one by one within a range of 0 to 198, for example, and reaches a maximum value (that is, 198) and then returns to 0. On the other hand, the other variation type counter CS2 is, for example, incremented one by one within a range of 0 to 240, and returns to 0 after reaching the maximum value (that is, 240). In the following description, CS1 is also referred to as “first variation type counter”, and CS2 is also referred to as “second variation type counter”.

  The first variation type counter CS1 determines the reach type of the first symbol, such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes, and the second variation type counter CS2 determines the final stop symbol ( In the present embodiment, a more detailed symbol variation mode such as an elapsed time (in other words, the number of variation symbols) until the middle symbol) stops is determined. Therefore, a variety of variation patterns can be easily realized by combining these variation type counters CS1 and CS2. It is also possible to determine the symbol variation mode only by the first variation type counter CS1, or to determine the symbol variation mode similarly by combining the first variation type counter CS1 and the stop symbol. The variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of the variation type counters CS1 and CS2 are acquired when the variation pattern is determined when the first symbol display device 81 starts the variation of the first symbol.

  The left, middle and right off symbol counters CL, CM and CR are used to determine the stop symbol of the left symbol row Z1, the middle symbol row Z2 and the right symbol row Z3 when the big hit lottery is missed. There are 20 first symbols in total, including the main symbol and the sub symbol, in each row of each column, so 20 counter values (0 to 19) are prepared for each. The left, upper, middle and lower symbols are determined by the out symbol counter CL, the upper, middle and lower symbols are determined by the out symbol counter CM, and the right symbol column is determined by the out symbol counter CR. The top, middle and bottom symbols are determined.

  In this embodiment, the values of the counters CL, CM, and CR are randomly updated by using the numerical value of the R register built in the MPU 701. That is, when each outlier symbol counter CL, CM, CR is updated, the lower 3 bits of the R register are added to the previous value, and when the addition result exceeds the maximum value, the current value is determined by subtracting 20. The Each outlier symbol counter CL, CM, CR is updated 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 703 front / rear symbol 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, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case.

  The second symbol random number counter C4 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The second symbol random number counter C4 is updated periodically (once every timer interruption in the present embodiment), and it is detected that the game ball has passed either the left or right second entrance (through gate) 67. Get when it is done. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the MPU 701 in the main controller 561 will be described with reference to the flowcharts of FIGS. 44 to 51. The MPU 701 is roughly divided into a main process that is started when the power is turned on, and a timer interrupt process that is started periodically (in this embodiment, at a cycle of 2 milliseconds (hereinafter referred to as “ms”)). And an NMI interrupt process activated by the input of the power failure signal SG1 to the NMI terminal. For convenience of explanation, the timer interrupt process and the NMI interrupt process will be described first, and then the main process will be described.

  FIG. 49 is a flowchart showing the timer interrupt process. The timer interrupt process is executed by the MPU 701 of the main controller 561 every 2 ms, for example. In the timer interruption process, first, reading process of various winning switches is executed (S601). That is, the state of various switches (except for the RAM erase switch 623) connected to the main controller 561 is read, and the state of the switch is determined and the detection information (winning detection information) is stored. Next, the random number initial value counter CINI is updated (S602). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 703.

  Further, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are updated (S603). Specifically, the jackpot random number counter C1, the jackpot symbol counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 703. After that, a start winning process is performed in accordance with winning in the first entrance 64 (S604).

  The start winning process will be described with reference to the flowchart of FIG. First, it is determined from the detection information of the operation port switch 524 whether or not the game ball has won (start winning) at the first entrance 64 (S701). If it is determined that the game ball has won the first entrance 64 (S701: Yes), is the number N of pending action balls of the first symbol display device 81 less than the upper limit (4 in the present embodiment)? It is determined whether or not (S702). If there is a winning at the first entrance 64 and the number N of activated balls is less than 4 (S702: Yes), the number N of activated balls is incremented by 1 (S703), and further updated in step S603. The values of the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3 are stored in the first area among the empty reserved areas in the reserved ball storage area of the RAM 703 (S704). On the other hand, there is no winning at the first entrance 64 (S701: No), or even if there is a winning at the first entrance 64, if the number N of operational reserves is not less than 4 (S702: No). , S703 and S704 are skipped, and the start winning process is terminated. After the start winning process is completed, the MPU 701 once ends the timer interrupt process.

  In addition, when the game ball wins the first entrance 64 (start winning), the first symbol display device 81 starts the variable display of the first symbol, but after the start winning, There is a restriction that a predetermined time (for example, 5 seconds) must elapse before the symbol changes and the symbol stops. Therefore, in the start winning process, when a start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process (S704). Specifically, since the start winning process is executed in a cycle of 2 ms, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 703 together with the values of the respective counters C1 to C3. In setting the first symbol variation pattern, which will be described later, the timer value is referred to, and a variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed).

  FIG. 51 is a flowchart showing the NMI interrupt process. The NMI interrupt process is executed by the MPU 701 of the main controller 561 when the power of the pachinko machine 10 is shut off due to the occurrence of a power failure or the like. By this NMI interrupt processing, the state of the main controller 561 at the time of power shut-off is stored in the backup area 703a of the RAM 703. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure, the power failure signal SG1 is output from the power failure monitoring circuit 742 to the NMI terminal of the MPU 701 in the main controller 561, and the MPU 701 interrupts the control being executed. NMI interrupt processing is started. The NMI interrupt processing program of FIG. 51 is stored in the ROM 702 of the main controller 561. For a predetermined time after the power failure signal SG1 is output, power is supplied from the power supply unit 741 so that the processing of the main controller 561 can be executed, and the NMI interrupt processing is executed within this predetermined time.

  In the NMI interrupt process, first, the used register is saved in the backup area 703a of the RAM 703 (S801), and the value of the stack pointer is stored in the backup area 703a (S802). Further, the occurrence information of the power shutdown is set in the backup area 703a (S803), and a power shutdown notification command indicating that the power is shut off is transmitted to another control device (S804). A RAM determination value is calculated and stored in the backup area 703a (S805). The RAM determination value is, for example, a checksum value at the work area address of the RAM 703. Thereafter, access to the RAM 703 is prohibited (S806), and the infinite loop is continued until the power supply is completely shut down and the processing cannot be executed.

  The above NMI interrupt process is executed in the same manner in the payout / release control device 611. With this NMI interrupt process, the state of the payout / release control device 611 at the time of power interruption due to the occurrence of a power failure or the like changes the backup area 713a of the RAM 713. Is remembered. Similarly, the power supply unit 741 supplies power so that the process of the payout / discharge control device 611 can be executed for a predetermined time after the power failure signal SG1 is output. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, the power failure signal SG1 is output from the power failure monitoring circuit 742 to the NMI terminal of the MPU 711 in the payout and emission control device 611, and the MPU 711 interrupts the control being executed. Then, the NMI interrupt process of FIG. 51 is started. The contents are the same as described above, except that the power-off notification command is not transmitted in step S804.

  FIG. 44 is a flowchart showing main processing executed by the MPU 701 in the main controller 561. This main process is started by a reset at power-on. In the main process, first, an initial setting process associated with power-on is executed (S101). Specifically, in order to set a predetermined value in the stack pointer and wait for the sub-side control devices (sound lamp control device 562, payout launch control device 611, etc.) to become operable. , Wait processing (for example, about 1 second) is executed. Next, a payout permission command is transmitted to the payout emission control device 611 (S102), and a pulsed clock signal SG3 is transmitted to the flip-flop circuit 762 of the main board removal detection circuit 706 (S120), and then the RAM 703. Is permitted (S103). In the process of S102, an operation permission command is transmitted also to the display control device 505, and when the operation permission command is received, the display control device 505 is in an operable state.

  The transmission of the clock signal SG3 performed in the process of S120 is performed after the initial setting process of the main control device 561, and after the operation permission command is transmitted to each of the control devices 611 and 505, and from the flip-flop circuit 762. When the main board removal signal SG4 is output, the control devices 561, 611, and 505 are operable, so that the main board removal signal SG4 can be reliably received and a reliable notification can be made. .

  Thereafter, it is determined whether or not the RAM erase switch 623 provided in the power supply device 612 is turned on (S104). If it is turned on (S104: Yes), processing is performed to clear (erase) the backup data. The process proceeds to S114. On the other hand, if the RAM erasure switch 623 is not turned on (S104: No), it is further determined whether or not the information on occurrence of power interruption is stored in the backup area 703a of the RAM 703 (S105). (S105: No), since backup data is not stored, in this case as well, the process proceeds to S114. If the occurrence information of power shutdown is stored in the backup area 703a (S105: Yes), the RAM judgment value is calculated (S106), and the calculated RAM judgment value is not normal (S107: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S114. As described above, the RAM determination value is, for example, a checksum value at the work area address of the RAM 703. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 703 is correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in a hall, the power is turned on while pressing the RAM erase switch 623. Therefore, if the RAM erase switch 623 is pressed, the process proceeds to the RAM initialization process (S114 to S116). Similarly, when the occurrence information of the power shutdown is not set, or when a backup abnormality is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (S114 to S116) of the RAM 703 in the same manner. That is, in the RAM initialization process from S114, the used area of the RAM 703 is cleared to 0 (S114), and the initial value of the RAM 703 is set (S115). Thereafter, the interrupt is permitted (S116), and the process proceeds to normal processing described later.

  On the other hand, if the RAM erase switch 623 is not turned on (S104: No), the occurrence information of power shutdown is stored (S105: Yes), and the RAM judgment value (checksum value etc.) is normal ( (S107: Yes), the process proceeds to S108, and a process at the time of power recovery (a process at the time of power-off restoration) is executed. That is, in the power recovery process, the stack pointer at the time of power interruption is restored (S108), and the information on occurrence of power interruption is cleared (S109). Next, a power-return command for returning the sub-side control device to the gaming state at the time of power-off is transmitted (S110), and the used register is returned from the backup area 703a of the RAM 703 (S111). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S112). If the interrupt is permitted (S112: Yes), the interrupt is permitted (S113), while the interrupt is prohibited when the power is turned off. If it is in the state (S112: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

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

  In the normal processing, first, output data such as a command updated in the previous processing is transmitted to each control device on the sub side (S201). Specifically, the presence / absence of winning detection information is determined, and if there is winning detection information, a winning ball payout command corresponding to the number of game balls acquired is transmitted to the payout launch control device 611. Further, when the first symbol display device 81 displays the variation of the first symbol, a stop symbol command, a variation pattern command, a confirmation command, and the like are transmitted to the display control device 505. In addition, after the start of the first symbol variation, each time normal processing is performed in the following order: variation pattern command → stop symbol command for left symbol column Z1 → stop symbol command for middle symbol column Z2 → stop symbol command for right symbol column Z3 The commands are transmitted one by one (that is, one every 4 ms), and the confirmation command is transmitted at the end of the fluctuation time.

  Next, each value of the variation type counters CS1 and CS2 is updated (S202). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 703. Further, the outlier counters CL, CM, and CR of the left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 are updated by the off symbol counter updating process (S203).

  Here, with reference to FIG. 46, the off symbol counter update process will be described. First, it is determined whether or not it is the update time of the out symbol counter CL of the left symbol row Z1 (S301), and if it is the update time (S301: Yes), the out symbol counter CL of the left symbol row Z1 is updated (S303). . Next, if it is not the update time of the left symbol row Z1 (S301: No), it is determined whether it is the update time of the out symbol counter CM of the middle symbol row Z2 (S302), and if it is the update time (S302: Yes). ), The outlier symbol counter CM of the middle symbol row Z2 is updated (S304). Furthermore, if it is not the update time of the middle symbol row Z2 (S302: No), the update symbol counter CR of the right symbol row Z3 is updated because it is the update time of the right symbol row Z3 (S305).

  In updating outlier symbol counters CL, CM, and CR in each of the processes of S303 to S305, the value of the lower 3 bits of the R register is added to the previous counter value, and 20 is added when the addition result exceeds the maximum value. Subtraction is performed, and the result of the calculation is taken as the current value of the symbol counters CL, CM, CR. According to the update process of CL, CM, CR, the outlier counters CL, CM, CR of the left symbol row Z1, the middle symbol row Z2, and the right symbol row Z3 are sequentially updated one by one in one normal process. Therefore, the update times of the counter 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, it is determined whether or not the combination of the updated off symbol counters CL, CM, and CR is a jackpot symbol combination (S306). finish. If it is not a jackpot symbol combination (S306: No), it is determined whether or not it is a reach symbol combination (S307). If it is a reach symbol combination (S307: Yes), then it is a front-rear reach. It is determined whether or not there is (S308). If it is a combination of front and rear detach reach (S308: Yes), the combination of the detachment symbol counters CL, CM and CR at that time is stored in the front and rear detach reach symbol buffer of the RAM 703 (S309). If the detachment symbol counters CL, CM, CR are a combination of reach other than front / rear detachment (S308: No), the combination of the detachment symbol counters CL, CM, CR at that time is stored in the reach symbol buffer other than front / rear detachment in the RAM 703 (S310). ). If the combination of outlier symbol counters CL, CM, CR is not a combination of jackpot symbol (S306: No) and not a combination of reach symbols (S307: No), the combination of outlier symbol counters CL, CM, CR is a reach symbol. In such a case, the combination of the off symbol counters CL, CM, CR is stored in the complete off symbol buffer of the RAM 703 (S311).

  After the off symbol counter CL, CM, CR update process (S203) is completed, the process returns to the normal process of FIG. 45, and the winning ball count signal and the payout abnormality signal received from the payout launch control device 611 are read (S204). A first symbol variation process for performing variation display of the first symbol by the one symbol display device 81 is executed (S205). By this first symbol variation process, jackpot determination, variation setting of the first symbol, and the like are performed. Details of the first symbol variation process will be described later with reference to FIG.

  After the end of the first symbol variation process, a large opening opening / closing process for opening or closing the specific winning opening (large opening) 65a of the variable winning device 32 is executed in the case of the big win state (S206). That is, the specific winning opening 65a is opened for each round of the big hit state, and it is determined whether the maximum opening time of the specific winning opening 65a has elapsed or whether a predetermined number of game balls have been won in the specific winning opening 65a. When any of these conditions is met, the specific winning opening 65a is closed. At this time, the specific winning opening 65a is allowed to be continuously opened on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Next, display control of the second symbol (for example, “◯” or “x” symbol) by the second symbol display device 82 is executed (S207). Briefly, on the condition that the game ball has passed through the second entrance (through gate) 67, the value of the second symbol random number counter C4 is acquired at the timing of passing and the second symbol display device 82. In the display unit 83, the second symbol variation display is performed. Then, the lottery of the second symbol is carried out based on the value of the second symbol random number counter C4, and when the winning state of the second symbol is reached, the electric accessory attached to the first entrance 64 is released for a predetermined time. Although not shown, the second symbol random number counter C4 is also updated by the timer interrupt process shown in FIG. 49, like the jackpot random number counter C1, the jackpot symbol counter C2, and the reach random number counter C3.

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

  On the other hand, if the predetermined time has not yet elapsed from the start of the previous normal processing (S208: No), the random number initial is within the remaining time until the predetermined time is reached, that is, until the next normal processing execution timing. The value counter CINI and the variation type counters CS1 and CS2 are repeatedly updated (S209, S210). First, the random number initial value counter CINI is updated (S209). Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 703. Next, the fluctuation type counters CS1 and CS2 are updated (S210). Specifically, the variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when the counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of the variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 703.

  Here, since the execution time of each process of S201-S207 changes according to the state of the game, the remaining time until the next normal process execution timing is not constant and varies. Therefore, it is possible to update the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) at random by repeatedly executing the update of the random number initial value counter CINI using the remaining time. The variation type counters CS1 and CS2 can also be updated at random.

  Next, the first symbol variation process (S205) will be described with reference to the flowcharts of FIGS. In the first symbol variation process, first, it is determined whether or not a big hit is currently being made (S401). The jackpot includes the jackpot game displayed on the first symbol display device 81 in the jackpot and the middle of a predetermined time after the jackpot game ends. As a result of the determination, if it is a big hit (S401: Yes), this processing is terminated as it is.

  If it is not a big hit (S401: No), it is determined whether or not the first symbol display device 81 is displaying the variation of the first symbol (S402). No), it is determined whether or not the number N of actuated balls of the first symbol display device 81 is greater than 0 (S403). If the number N of active suspension balls is 0 (S403: No), this process is ended as it is. If the number of the operation holding balls N> 0 (S403: Yes), the operation holding ball number N is decremented by 1 (S404), and the data stored in the holding ball storage area is shifted (S405). This data shift process is a process of sequentially shifting the data stored in the reserved first to fourth areas of the reserved ball storage area to the execution area side, and the reserved first area → execution area, reserved second area → The data in each area is shifted such as the first hold area, the third hold area → the second hold area, the fourth hold area → the third hold area. After the data shift process, the first symbol variation start process is executed (S406). The variation start process will be described later with reference to FIG.

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

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

  When it is determined that the game is a big hit (S501: Yes), the symbol corresponding to the value of the jackpot symbol counter C2 stored in the execution area of the reserved ball storage area, that is, the jackpot symbol is the value of the jackpot symbol counter C2 and the symbol. The symbol is obtained based on a table (not shown) representing the corresponding relationship, and the symbol is set as a stop symbol command (S502). At this time, the numbers 0 to 49 of the jackpot symbol counter C2 correspond to any of the 50 jackpot symbols on all five active lines, and any one of the 50 jackpot symbols is set in the stop symbol command. Is done. Among these jackpot symbols, when a predetermined specific symbol (in this embodiment, an odd-numbered main symbol) is arranged, the process proceeds to a probabilistic state, but a symbol that is not a specific symbol (in this embodiment, even number) When the numbers are aligned with the main symbols), the state does not shift to the probability variation state.

  Next, the variation pattern of the first symbol until it stops at the jackpot symbol is determined, and the variation pattern is set in the variation pattern command (S503). At this time, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 703 are checked, and the reach type such as normal reach, super reach, premium reach, and other rough types are determined based on the value of the first variation type counter CS1. And the elapsed time until the final stop symbol (in this embodiment, middle symbol Z2) stops after occurrence of reach based on the value of the second variation type counter CS2 (in other words, the number of variable symbols) ) Etc. to determine a finer pattern variation mode. The relationship between the numerical value of the first variation type counter CS1 and the reach pattern and the relationship between the numerical value of the second variation type counter CS2 and the stop symbol time are respectively defined in advance by a table or the like. However, the variation pattern can be set using only the value of the first variation type counter CS1 without using the value of the second variation type counter CS2. Whether to set the pattern or to set the pattern with both values of both variation type counters CS1 and CS2 is appropriately determined according to the value of the first variation type counter CS1 and the game conditions each time. The same applies to the setting of the fluctuation pattern in the case of performing front / rear out of reach display, reach display other than front / rear out, and complete out of display described later.

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

  When front / rear out of reach has occurred (S505: Yes), the left, middle, and right out of symbol counters CL, CM, CR stored in the front / rear out of reach design buffer of the RAM 703 are set as stop symbol commands ( S506). In addition, a variation pattern for displaying the front / rear out of reach is determined, and the variation pattern is set in the variation pattern command (S507). At this time, similarly to the processing of S503, the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 703 are checked, and the normal reach, super reach, and premium reach are determined based on the value of the first variation type counter CS1. The reach type (such as the middle symbol in the present embodiment) is stopped after the occurrence of the reach based on the value of the second variation type counter CS2 In other words, a more detailed symbol variation mode such as the number of variation symbols) is determined.

  When a reach other than front / rear out is generated (S505: No), each value of left, middle and right out of symbol counters CL, CM, CR stored in the reach symbol buffer other than front / rear out of RAM 703 is set as a stop symbol command. (S508). Further, a variation pattern for reach display other than front / rear deviation is determined, and the variation pattern is set in a variation pattern command (S509). At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 703, as in the process of S503.

  If neither big hit nor reach (S501: No, S504: No), the left, middle, and right out symbol counters CL, CM, and CR stored in the complete out symbol buffer of the RAM 703 are stopped. The symbol command is set (S510). Also, a variation pattern for complete out-of-range display is determined, and the variation pattern is set as a variation pattern command (S511). At this time, the variation pattern is determined based on the values of the variation type counters CS1 and CS2 stored in the counter buffer of the RAM 703, as in the process of S503. As described above, when the setting of the stop symbol command and the variation pattern command is completed in any of the big hit, the reach occurrence, and the non-reach occurrence, this processing is ended.

  Next, with reference to FIG. 52, the payout and launch control executed by the MPU 711 in the payout launch control device 611 will be described. FIG. 52 is a flowchart showing a main process of the payout / discharge control device 611, and this main process is started by a reset at power-on.

  First, initial setting processing accompanying power-on is executed (S901). Specifically, a predetermined value set in advance is set in the stack pointer, and an interrupt mode is set. Next, it waits for reception of the payout permission command transmitted from the main controller 561 (S902: No). When a payout permission command is received (S902: Yes), RAM access is permitted (S903), and an external interrupt vector is set (S904).

  Thereafter, data backup processing is executed for the RAM 713 in the MPU 711. Specifically, it is determined whether or not the RAM erase switch 623 provided in the power supply device 612 is pressed (S905). If it is turned on (S905: Yes), the backup data is cleared (erased). The process proceeds to S915. On the other hand, if the RAM erasure switch 623 is not turned on (S905: No), it is further determined whether or not the power interruption occurrence information is stored in the backup area 713a of the RAM 713 (S906). (S906: No), since the backup data is not stored, in this case as well, the process proceeds to S915. If the occurrence information of power shutdown is stored in the backup area 713a (S906: Yes), the RAM judgment value is calculated (S907), and the calculated RAM judgment value is not normal (S908: No), that is, calculated. If the RAM determination value does not match the RAM determination value stored when the power is shut off, the backed up data has been destroyed. In such a case as well, the process proceeds to S915. As described above, the RAM determination value is a checksum value at a work area address of the RAM 713, for example. Instead of the RAM determination value, the validity of the backup may be determined based on whether or not the keyword written in a predetermined area of the RAM 713 is correctly stored.

  In the RAM initialization process from S915, the used area of the RAM 713 is cleared to 0 (S915), and the initial value of the RAM 713 is set (S916). Thereafter, the MPU 711 peripheral device is initialized (S917), an interrupt is permitted (S918), and the process proceeds to a payout launch control process described later.

  On the other hand, if the RAM erase switch 623 has not been pressed (S905: No), the occurrence information of the power shutdown has been set (S906: Yes), and the RAM judgment value (checksum value etc.) is normal ( S908: Yes), processing at power recovery (processing at power-off restoration) is executed. That is, the stack pointer at the time of power shutdown is restored (S909), and the information on occurrence of power shutdown is cleared (S910). The MPU 711 peripheral device is initialized (S911), and the used register is restored from the backup area 713a of the RAM 713 (S912). Further, it is confirmed whether or not the interrupt is permitted before the power is turned off (S913). If the interrupt is permitted (S913: Yes), the interrupt is permitted (S914), while the interrupt is prohibited when the power is turned off. If it is in the state (S913: No), the processing is returned to the address before the power is shut off while the interruption is prohibited.

  Next, with reference to the flowchart of FIG. This payout launch control process is executed following the main process of the payout launch control device 611. In the payout launch control process, first, a command from the main control device 561 is acquired, and the total number of prize balls is stored (S1001). Next, the touch control of the operation handle and the state of the rotation amount are detected, and a firing control process for exciting the firing solenoid 92 and the electromagnet 104 as necessary is performed (S1002). Next, as a result of checking the state return switch 621, when it is determined that the state return operation starts, the state return operation is executed (S1003).

  Thereafter, the setting of the lower plate full state or the lower plate full state is executed according to the change in the state of the lower plate 301 (S1004). That is, when the lower pan 301 is detected based on the detection signal of the lower pan full switch, the lower pan full state is set when the lower pan is full, and when the lower pan full is not reached. , Set the lower pan full release state. Further, the setting of the tank ball absence state or the tank ball absence release state is executed according to the change in the state of the tank ball (S1005). In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration. Thereafter, the presence / absence of the state to be notified is determined, and if there is a state to be notified, the 7-segment LED provided in the payout launch control device 611 is notified (S1006).

  Next, prize ball payout processing is executed by each processing of S1007 to S1009. That is, if the prize ball is not paid out and the total number of prize balls stored in the process of S1001 is not 0 (S1007: No, S1008: No), the prize ball control process shown in FIG. 54 is started (S1009). . On the other hand, if the prize ball cannot be paid out (S1007: Yes) or if the total number of prize balls is 0 (S1008: Yes), the process proceeds to a lending payout process. The prize ball control process will be described later.

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

  In the ball removal process (S1013), the state return switch 621 is checked to execute the ball removal process by driving the dispensing motor 658a on the condition that the ball removal disabled state is not set and the ball removal operation is not started. Subsequently, the control of vibrator 660 (vibrating motor control) is executed on the condition that the ball is clogged (S1014). Thereafter, the process returns to the top of the payout / release control process, and thereafter, the process described above is repeated.

  Next, the prize ball control process shown in FIG. 54 will be described. In the winning ball control process, firstly, the payout motor 658a is driven to rotate in the forward direction to pay out the winning ball (S1101). Whether the rotation of the payout motor 658a is normal is determined based on the detection result of the payout rotation sensor (S1102). If not normal (S1102: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a. The stop process is executed (S1103), and then the process returns to the payout launch control process of FIG.

  If the rotation of the payout motor 658a is normal (S1102: Yes), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (S1104). If the game ball count is not normal (S1104: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a is stopped (S1105). Return to.

  Further, if the game ball count is normal (S1104: Yes), it is determined whether or not the game ball count by the payout count switch has reached the total number of prize balls and the payout is completed (S1106). If completed (S1106: Yes), a stop process of the payout motor 658a is executed (S1107), and then the process returns to the payout launch control process of FIG. On the other hand, if the payout is not completed (S1106: No), the process returns to the payout launch control process of FIG.

  The lending control process shown in FIG. 55 will be described. In the ball lending control process, first, the payout motor 658a is driven to rotate in the reverse direction to pay out a lending ball (S1201). Whether the rotation of the payout motor 658a is normal is determined based on the detection result of the payout rotation sensor (S1202). If not normal (S1202: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a. The stop process is executed (S1203), and then the process returns to the payout launch control process of FIG.

  If the rotation of the payout motor 658a is normal (S1202: Yes), it is determined from the detection result of the payout count switch whether or not the game ball is normally counted (S1204). If the game ball count is not normal (S1204: No), the payout motor 658a is driven to execute a retry process and the payout motor 658a is stopped (S1205). Return to.

  Further, if the game ball count is normal (S1204: Yes), it is determined whether or not the game ball count by the payout count switch has reached a predetermined number (25) and the payout is completed ( If the payout has been completed (S1206: Yes), the payout motor 658a is stopped (S1207), and the process returns to the payout launch control process of FIG. On the other hand, if the payout has not been completed (S1206: No), the process returns to the payout launch control process of FIG.

  Next, a main process executed by the MPU 721 in the display control apparatus 505 will be described with reference to FIG. FIG. 56 is a flowchart showing main processing executed by the MPU 721 in the display control device 505.

  The main processing of the display control device 505 is executed by supplying a drive voltage from the power supply device 612. First, each processing is executed (S1300). In each process, the operation of the pachinko machine 10 such as the process of making the apparatus operable when the reception of the operation permission command is confirmed and confirming the reception, the sound output of the speaker by the sound lamp control device 562, the lighting of the lamp, etc. Processing, processing for displaying a display symbol by the first symbol display device 81 and the second symbol display device 82, and the like are performed.

  When each processing is completed, it is confirmed whether or not the main board removal signal SG4 is input from the main board removal detection circuit 706 (S1301). If the main board removal signal SG4 is not input (S1301: No) ), The process returns to the process of S1300, and each process is repeatedly executed. If the main board removal signal SG4 is input (S1301: Yes), the fact that the main board on which the main controller 561 is mounted has been removed to the outside. A notification process is performed for notification (S1302), and the main process ends.

  In the notification process, the voice lamp control device 562 is instructed to notify that the main control device 561 has been removed. When the sound lamp control device 562 receives an instruction from the display control device 505, the sound lamp control device 562 notifies the error display lamp 206. The first symbol display device 81 may display a symbol or a character that recognizes that the main control device 562 has been removed. Even when the main control device 561 is removed, the display control device 505, the main control device 561, and the payout launch control device continue to perform each control, so that the notification by the error display lamp 206 can be reliably performed. it can.

  Next, a second embodiment will be described with reference to FIG. FIG. 58 is an electric circuit diagram schematically illustrating an electrical connection state between the main board removal detection device 706 and the power supply device 612 according to the second embodiment. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and the description is abbreviate | omitted.

  As shown in FIG. 58, the main board removal detection circuit 706 of the second embodiment is mounted on a main board removal detection board 764 which is a board different from the main board of the main controller 561. The drive voltage and the backup voltage are supplied to the main board removal detection board 764 via the power relay port 765 of the main controller 561.

  Therefore, when the main control device 561 is removed, the supply of the backup voltage of the flip-flop circuit 762 is cut off as in the first embodiment, so that the drive voltage is supplied and the CK of the flip-flop circuit 762 is supplied. When the clock signal SG3 is input to the terminal, an H level output is performed from the Q2 terminal of the flip-flop circuit 762. Therefore, since the main board removal signal SG4 is output from the Q2 terminal of the flip-flop circuit 762 and notification is performed by the sound lamp control device 562, a device that replaces the illegal ROM or illegally generates a jackpot is attached. It can be easily confirmed that there is a possibility.

  In addition, when an unauthorized person who replaces the illegal ROM or installs a device that illegally generates a jackpot knows that the error display lamp 206 is notified when the main control board 561 is removed. A case where the main controller 561 is crafted so as not to be notified by the error display lamp 206 can be considered. However, in the second embodiment, the main board removal detection board 764 on which the main board removal detection circuit 706 is mounted is different from the main board on which the main controller 561 is mounted. Even if it is specially crafted, since the output state of the flip-flop circuit 762 changes, the notification by the error display lamp 206 can be reliably performed.

  Since the main board removal detection board 764 on which the main board removal detection circuit 706 is mounted and the main board on which the main controller 561 is mounted are different boards, they are arranged at positions apart from each other. It is good as a thing. Here, the fraudster knows that the error display lamp 206 is notified when the main control board 561 is removed, and tried to craft the main board removal detection board 764 and the main board. In this case, it is necessary to remove the main board removal detection board 764 and the main board, which are arranged at a distant position, and perform the work. Therefore, since the work for performing an illegal act becomes complicated, the illegal act can be suppressed.

  Further, since the main board removal detection board 764 on which the main board removal detection circuit 706 is mounted is different from the main board on which the main controller 561 is mounted, the main board removal detection board 764 is used as the pachinko machine 10. It is good also as what arrange | positions in the place where it is hard to visually recognize in the back view. If the main board removal detection board 764 is disposed in a place where it is difficult to see in the back view of the pachinko machine 10, the presence of the main board removal detection circuit 706 is not known to the fraudulent person, so that the notification is made more reliably. It can be performed.

  Next, a third embodiment will be described with reference to FIG. FIG. 59 is an electric circuit diagram schematically illustrating an electrical connection state between the main board removal detection circuit 764 and the power supply device 612 according to the third embodiment. In addition, the same code | symbol is attached | subjected to the part same as 1st Embodiment, and the description is abbreviate | omitted.

  In the third embodiment, a RAM erase switch is used in place of the reset switch 559 operated to change the output state of the flip-flop circuit 762 (Q1 terminal is set to H level and Q2 terminal is set to L level). When the 623 is operated, the output state of the flip-flop circuit 762 is changed. Therefore, the RAM erase switch circuit 743 of the power supply device 612 and the A terminal of the OR circuit 763 are connected, and a signal is input to the D terminal of the flip-flop circuit 762 when the RAM erase switch 623 is operated.

  In the third embodiment, an OR circuit 766 is provided separately from the OR circuit 763. Since the RAM erase switch 623 is operated to erase the storage in the backup areas 703a and 713a of the RAMs 703 and 713, it is necessary to output the RAM erase signal SG2 to the main controller 561 and the payout / release controller 611. Therefore, the RAM erase switch circuit 743 is connected to the A terminal of the OR circuit 766, and the Y terminal of the OR circuit 766 is connected to the input / output port 705. When the RAM erase switch 623 is operated, the input / output The RAM erase signal SG2 is input to the control devices 561 and 611 via the port 705.

  When the main board removal signal SG4 is output from the Q2 terminal of the flip-flop circuit 762, the backup voltage supplied from the power supply unit 741 of the power supply device 612 is cut off. A failure, disconnection of the backup voltage supply path Vbb, a case where the main controller 561 is removed, and the like are considered, and an abnormality has occurred in the pachinko machine 10. Since normal control cannot be performed if control is started by the main controller 561 in a state where an abnormality has occurred in the pachinko machine 10, it is preferable to delete the storage in the backup areas 703a and 713a. Therefore, even when the Q2 terminal of the flip-flop circuit 762 and the B terminal of the OR circuit 766 are connected and the main circuit board removal signal SG4 is output from the Q2 terminal of the flip-flop circuit 762, the Y of the OR circuit 766 is also output. A RAM erase signal SG2 is output from the terminal.

  As described above, in the third embodiment, since the RAM erase switch 623 can change the output state of the flip-flop circuit 762 to cancel the notification by the error display lamp 206, it is necessary to newly provide a reset switch. There is no need to change the design of each board box. Therefore, it is possible to prevent the manufacturing cost of the pachinko machine 10 from increasing.

  Further, when the main controller 561 is removed, the supply of the backup voltage to the flip-flop circuit 762 is cut off as in the first embodiment, so that the main board is removed from the Q2 terminal of the flip-flop circuit 762. Since the external signal SG4 is output and the notification is performed by the sound lamp control device 562, it can be easily confirmed that the device has been replaced with an unauthorized ROM or a device that illegally generates a jackpot.

  In the third embodiment, the main board removal detection circuit 706 is mounted on the main board of the main controller 561. However, as in the second embodiment, the main board removal detection board 764 is used. In addition, a main board removal detection circuit 706 may be mounted.

  The present invention has been described above based on one embodiment. However, the present invention is not limited to the above embodiment, and various modifications and improvements can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the first embodiment, the reset switch 559 is provided in the board box 563, but the reset switch 559 may be provided in a place that is difficult to see in the back view of the pachinko machine 10. In such a configuration, even if the existence of the reset switch 559 is known, the arrangement position cannot be visually recognized, and thus it takes time to search for the reset switch 559. Therefore, since it takes time to replace the illegal ROM or to install a device that generates an illegal jackpot, it is possible to suppress an illegal act.

  In each of the above embodiments, when the main control device 561 is removed for notification, the error display lamp 206 is notified by the instruction of the audio lamp control device 562. However, the Q2 of the flip-flop circuit 762 is used. Notification may be made by connecting a light emitting diode or the like to the terminal.

  In each of the above embodiments, the flip-flop circuit 762 and the OR circuit 763 are provided, and the fact that the main controller 561 has been removed from the pachinko machine 10 based on the supply state of the backup voltage to the flip-flop circuit 762 is stored. However, the storage means for storing that the main controller 561 has been removed may be configured by various electronic components other than the flip-flop circuit 762.

  Further, in each of the above embodiments, the clock signal SG3 is transmitted from the MPU 701. However, when a predetermined time elapses after the power supply device 612 is connected to the CK terminal and the power supply device 612 supplies the drive voltage, the clock signal SG3 is transmitted. The signal SG3 may be transmitted. In this configuration, since the clock signal SG3 can be transmitted from the power supply device 612, the clock signal SG3 can be reliably transmitted after the supply of the drive voltage is completed. Accordingly, since the clock signal SG3 can be prevented from being input to the CK terminal before the flip-flops 762 and 770 rise, output corresponding to the input of the D terminal can be accurately performed.

  Further, as shown in the above embodiment, the variable display, which is a kind of dynamic display, is not limited to the one in which the symbol as identification information is scrolled in the vertical direction on the display screen of the first symbol display device 81. It may be performed by moving and displaying a symbol along a predetermined route such as a direction or an L shape. In addition, the dynamic display of the identification information is not limited to the display of variation of the symbol. The effect display etc. which are displayed are also included. In this case, one or more characters are used as identification information together with the symbols or separately from the symbols.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, the present invention may be applied to a so-called second type pachinko gaming machine having a winning device having a special area such as a V zone. Further, in addition to the pachinko machine, the game machine may be implemented as another game machine such as an alepacchi or a sparrow ball.

  You may implement this invention in the pachinko machine etc. of a type different from the said embodiment. For example, once a big hit, a pachinko machine that raises the expected value of the big hit until a big hit state occurs (for example, two times or three times) including that (for example, a two-time right item, a three-time right item) May also be implemented. Further, after the jackpot symbol is displayed, it may be implemented as a pachinko machine that generates a special game that gives a player a predetermined game value on the condition that a ball is won in a predetermined area. Further, the present invention may be implemented in a pachinko machine that has a special area such as a V-zone and has a special gaming state as a necessary condition for winning a ball in the special area. Further, in addition to the pachinko machine, the game machine may be implemented as various game machines such as an alepatchi, a sparrow ball, a slot machine, a game machine in which a so-called pachinko machine and a slot machine are integrated.

  In the slot machine, for example, a symbol is changed by operating a control lever in a state where a symbol effective line is determined by inserting coins, and a symbol is stopped and confirmed by operating a stop button. Is. Accordingly, the basic concept of the slot machine is that it is provided with a display device for confirming and displaying the identification information after variably displaying the identification information string composed of a plurality of identification information, and resulting from the operation of the starting operation means (for example, the operation lever). The variation display of the identification information is started, and the variation display of the identification information is stopped and fixedly displayed due to the operation of the operation means for stop (for example, the stop button) or when a predetermined time elapses. It is a slot machine that generates a special game that gives a player a predetermined game value on the condition that the combination of identification information at the time is a specific condition. In this case, the game medium is typically a coin, medal, etc. Take as an example.

  In addition, as a specific example of a gaming machine in which a pachinko machine and a slot machine are fused, a display device is provided that displays a symbol after a symbol string composed of a plurality of symbols is variably displayed, and has a handle for launching a ball. What is not. In this case, after throwing a predetermined amount of spheres based on a predetermined operation (button operation), for example, the change of the symbol is started due to the operation of the operation lever, for example, due to the operation of the stop button, or With the passage of time, the variation of the symbol is stopped, and a special game that gives a predetermined game value to the player is generated on the condition that the determined symbol at the time of stoppage is a so-called jackpot symbol. In this case, a large amount of balls are paid out to the lower tray.

  Below, the gaming machine and the modification of the present invention are shown. A board that controls the game and is equipped with a connector for electrical connection with other devices, and supplies the drive voltage necessary for the progress of the game, including the main board, to each part of the gaming machine A main power supply unit, a sub power supply unit capable of supplying a drive voltage to a part of the gaming machine even when the supply of the drive power by the main power supply unit is cut off, and at least the main board with respect to the sub power supply unit A power input unit to which a drive voltage is supplied by being electrically connected via a connector mounted on the first input unit, and a first input unit to which a signal is input at a timing when the supply of the drive voltage is started by the main power unit A second input unit that receives a signal separately from the first input unit, and a signal corresponding to the input signal of the second input unit at a timing when the signal is input to the first input unit. Provided that the drive voltage is supplied to A first signal output circuit in which at least a part of the signal output unit and the second input unit are electrically connected to each other. When the driving voltage is continuously supplied to the power input unit, a predetermined signal is output from the signal output unit, and after the predetermined signal is output, the supply of the driving voltage from the sub power unit to the power input unit is canceled, and then The gaming machine 1 is characterized in that when a driving voltage is supplied to the power input unit again and a signal is input to the first input unit, a signal output from the signal output unit is switched.

  According to the gaming machine 1, by confirming that the signal output from the signal output unit of the first signal output circuit has been switched, supply of the drive voltage to the power input unit of the first signal output circuit by the sub power supply unit Can be confirmed. When the supply of the driving voltage by the sub power supply unit is canceled, the connector may have been removed. Therefore, it is possible that the main board was removed from the gaming machine and an illegal act was performed. However, according to the gaming machine 1, it is possible to know that the main board may have been removed by checking the signal output from the signal output unit of the first signal output circuit. In the case where an illegal act is performed by inspecting, it is possible to easily find the illegal act.

  In the gaming machine 1, the signal output unit of the first signal output circuit may be electrically connected to at least one of a display unit that performs visual notification or an audio unit that performs audio notification. With this configuration, when the signal output from the signal output unit of the first signal output circuit is switched, the state of the display unit or the state of the audio unit is changed to change the state of the first signal output circuit. It can be confirmed that the supply of the drive voltage by the sub power supply unit to the power supply input unit has been released. Further, one of the display means may be a lamp, and the state of the lamp may be changed from off to on or flashing, and one of the display means may be a liquid crystal display device. The display mode may be changed from a display based on a normal game to a display suggesting that the supply of the driving voltage by the sub power supply unit has been released. In addition, one of the sound means may be a speaker, and the state of the speaker may be changed from silence to a sound output state. In this configuration, since the state changes visually or audibly, it can be surely known that the supply of the drive voltage by the sub power supply unit to the power input unit of the first signal output circuit has been released. Therefore, since visual or audible notification is performed, it is possible to easily find a gaming machine in which a connector may be removed and an illegal act may be performed on the main board. In addition, the lamp state may be changed from lighting or blinking to extinguishing, and the speaker state may be changed from sound output to silence. Furthermore, it is good also as what changes the state by operating the movable member with which shape change provided in the gaming machine is operated. It is also possible to check and confirm the signal output part of the first signal output circuit with a tester or the like. That is, any device connected to the signal output unit of the first signal output circuit may be used as long as it can be notified that the drive voltage by the sub power supply unit has been released by changing the state.

  In the gaming machine 1, information associated with the progress of the game performed on the main board is stored, and also stored information after the drive voltage is supplied by the sub power supply unit and the supply of the drive voltage by the main power supply unit is cut off. A gaming machine 2 comprising storage means for holding the game machine.

  According to the gaming machine 2, information associated with the progress of the game performed on the main board is stored in the storage means. The storage means is supplied with the drive voltage from the sub power supply unit, and retains the stored information even after the supply of the drive voltage from the main power supply unit is cut off. Therefore, even when the supply of the drive voltage by the main power supply unit is interrupted, the storage means stores the information before the drive voltage is interrupted. Therefore, when the drive voltage by the main power supply unit is supplied again, the drive voltage is cut off. It is possible to return to the previous state. In addition, since the driving voltage is supplied by the sub power supply unit, the power supply unit supplied to the storage unit and the first signal output circuit can be shared, and a new power supply unit is required to hold the storage unit information. There is no.

  In the gaming machine 1 or 2, the predetermined signal output from the signal output unit is input to the second input unit, and the first signal output circuit has a predetermined signal input to the second input unit. The gaming machine 3 is configured such that when a signal is input to the first input unit in a state of being, a predetermined signal is output from the signal output unit.

  According to the gaming machine 3, the predetermined signal output from the signal output unit is input to the second input unit. The first signal output circuit outputs a predetermined signal from the signal output unit when a signal is input to the first input unit while the signal is input to the second input unit. Therefore, while the supply of the driving voltage by the sub power supply unit is continued, a predetermined signal is output from the signal output unit, so that the signal output from the signal output unit is not switched. Therefore, it is possible to prevent the state of the state change unit from changing, and it is possible to improve the reliability when the state of the state change unit changes.

  In any one of the gaming machines 1 to 3, the first signal output circuit includes switch means configured to be operable from the outside and configured to input a signal to the second input unit when operated. The game machine 4 is configured such that when the switch means is operated and a signal is input to the second input unit, a predetermined signal is output from the signal output unit.

  The gaming machine 4 is provided with switch means configured to be operable from the outside and configured to input a signal to the second input unit when operated. When a signal is input to the two input units, a predetermined signal is output from the signal output unit of the first signal output circuit. For example, it may be possible to remove the main board by checking the inspection stage at the gaming machine factory or repairing the gaming machine. In such a case, the signal output from the signal output unit of the first signal output circuit is a predetermined signal. Will switch from. If the work for returning the signal output from the signal output unit is complicated, the check work and the repair work take much time and the efficiency is lowered. However, according to the gaming machine 4, since a predetermined signal is output from the signal output unit by operating the switch means, it is possible to reduce a decrease in work efficiency.

  It should be noted that the switch unit may be disposed at a location where visual recognition is difficult on the back surface of the gaming machine. In this configuration, since the switch means cannot be found unless the structure of the gaming machine is known in detail, the reset operation cannot be performed when the supply of the drive voltage by the sub power supply unit is released. Therefore, since the signal output from the signal output unit of the first signal output circuit is switched, the crime prevention property is improved.

  In the gaming machine 4, information associated with the progress of the game performed on the main board is stored, and also stored information after the driving voltage is supplied by the sub power supply unit and the driving voltage supply by the main power supply unit is cut off. The gaming machine 5 is characterized in that the gaming machine 5 includes an initialization switch operated to initialize information stored in the storage means.

  According to the gaming machine 5, the switch means is composed of an initialization switch that initializes the information held in the storage means, so that the signal output from the signal output unit of the first signal output circuit is a predetermined signal. It is possible to use both a switch for generating a signal and a switch for initializing stored information in the storage means. The initialization switch also has a role to release the abnormality when an abnormality occurs in a gaming machine, and is equipped with a general gaming machine. It is possible to reduce the increase.

  The switch means of the gaming machine 4 or 5 may be a push button type switch or a select type switch. In particular, in a select-type switch, a key switch that can be inserted and removed may be used. When a key switch is used, only a specific person owns the key, so that the switch means is operated by an unauthorized person or the like and the output from the signal output unit of the first signal output circuit is changed to a predetermined signal. Can be prevented.

  In the gaming machine 5, the signal output unit of the first signal output circuit includes a first output unit that outputs the predetermined signal and a second output unit that is different from the first output unit, and outputs from the signal output unit. When the signal to be switched is switched, the output is made from the second output unit, and when the signal is outputted from the second output unit, the main board initially stores the information held in the storage means A gaming machine 6 characterized by being controlled so as to be converted into a game machine.

  According to the gaming machine 6, the signal output unit of the first signal output circuit includes a first output unit that outputs a predetermined signal and a second output unit that is different from the first output unit. When the output signal is switched, the signal is output from the second output unit. When a signal is output from the second output unit, information held in the storage means is initialized by controlling the main board. When the signal output from the signal output section is switched, the connector may have been removed and the main board may have been removed. There is no possibility. Therefore, it is preferable to initialize information associated with the game stored in the storage means. According to the gaming machine 6, when the signal output from the signal output unit is switched, the information in the storage means is initialized by the control of the main board, so that erroneous control can be prevented. .

  In any of the gaming machines 4 to 6, the signal output section of the first signal output circuit and the switch means are connected to the input terminal, and the output terminal is connected to the second input section of the first signal output circuit. And input / output means for outputting 1 when any of the input terminals is input, and the first signal output circuit receives a signal from the output terminal of the input / output means to the second input section. The gaming machine 7 is configured such that when a signal is input to the first input unit in a state in which the signal is input, a predetermined signal is output from the signal output unit.

  According to the gaming machine 7, the signal output unit of the first signal output circuit and the switch means are connected to the input terminal of the input / output means, and the second signal of the first signal output circuit is connected to the output terminal of the input / output means. The input unit is connected. The first signal output circuit outputs a predetermined signal from the signal output unit when a signal is input to the first input unit while a signal is input from the output terminal of the input / output means to the second input unit. Therefore, since each signal for outputting a predetermined signal from the signal output unit of the first signal output circuit is input to the second input unit as one output, the electrical wiring can be reduced, and the power can be saved. Space can be achieved.

  Any one of the gaming machines 1 to 7 includes a signal output means for outputting a signal to the first input section of the first signal output circuit when a drive voltage is supplied from the main power supply section. A gaming machine 8 characterized by:

  According to the gaming machine 8, when a drive voltage is supplied from the main power supply unit, a signal is output to the first input unit of the first signal output circuit by the signal output unit. The first signal output circuit outputs a signal corresponding to the input signal of the second input unit from the signal output unit when the signal to the first input unit is input. For example, when the signal of the signal output unit is switched Is switched after the signal output by the signal output means is input to the first input unit. Therefore, it can be confirmed when the drive voltage is supplied whether or not the supply of the drive voltage to the first signal output circuit by the sub power supply unit is released. In addition, when the supply of the driving voltage to the first signal output circuit is released by removing the main board, it is possible to confirm that the main board has been removed before the installation hall starts business. Therefore, it is possible to reduce the operation of the gaming machine in which the illegal act has been performed as it is.

  In the gaming machine 8, the signal output means outputs a signal to the first input unit of the first signal output circuit after a predetermined time has elapsed after the drive voltage is supplied by the main power supply unit. A gaming machine 9 characterized by being.

  According to the gaming machine 9, the signal output means outputs a signal to the first input unit of the first signal output circuit after a predetermined time has elapsed after the drive voltage is supplied by the main power supply unit. The timing at which a signal is input to one input unit is after the drive voltage from the main power supply unit is supplied to each unit of the gaming machine. Therefore, the gaming machine can reliably cope with the signal output from the signal output unit of the first signal output circuit.

  In any one of the gaming machines 1 to 9, the first signal output circuit is mounted on the main board and the main board is encapsulated by an encapsulating member, and the sub power supply unit is external to the encapsulating member. A gaming machine 10, which is arranged in the above.

  According to the gaming machine 10, the first signal output circuit is mounted on the main board and the main board is encapsulated by the encapsulating member, and the sub power supply unit is disposed outside the encapsulating member. When the connector is removed in order to remove the encapsulating member from the gaming machine, the supply of the driving voltage to the main board by the sub power source is cut off. Accordingly, since the supply of the drive voltage to the power supply input unit of the first signal output circuit is canceled, when the drive voltage from the main power supply unit is supplied again, it is output from the signal output unit of the first signal output circuit. The signal is switched and it can be known that the main board has been removed.

  In any one of the gaming machines 1 to 9, at least the main board is encapsulated by an encapsulating member, and the first signal output circuit and the sub power supply unit are disposed outside the encapsulating member and Connected to the board by connectors, and is driven to the first signal output circuit via a connector for connecting the first signal output circuit and the main board and a connector for connecting the sub power supply unit and the main board.

  According to the gaming machine 11, the main board is encapsulated by the encapsulating member. The first signal output circuit and the sub power supply unit are disposed outside the encapsulating member and are connected to the main board by connectors. The drive voltage supplied to the first signal output circuit is supplied via a connector that connects the first signal output circuit and the main board and a connector that connects the sub power supply unit and the main board. Therefore, when removing the encapsulating member encapsulating the main board in order to perform an illegal act, it is necessary to remove the connectors, respectively, the connector for connecting the first signal output circuit and the main board, the sub power supply unit, When either one of the connectors for connecting to the board is removed, the supply of the drive voltage to the first signal output circuit is released. Therefore, when the drive voltage from the main power supply unit is supplied again, the signal output from the signal output unit of the first signal output circuit is switched, and it can be known that the main board has been removed. The drive voltage supplied to the first signal output circuit when at least one of the connector connecting the main board and the first signal output circuit and the connector connecting the main board and the sub power supply unit is removed.
