<Basic operation of pachinko gaming machines>
In the pachinko gaming machine PM configured as described above, the outer frame 1 is fixedly installed on the game island of the game facility, the front frame 2, the glass frame 5, etc. are closed and locked, and the pachinko machine PM is used for the game. The game is started by storing the game ball in the plate 6 and rotating the firing handle 9. When the launch handle 9 is rotated, the game balls stored in the upper ball plate 6 are sent out to the launch mechanism 27 one by one by the ball feed mechanism 26 arranged on the back side of the glass frame 5. It is launched into the game area PA by the launch mechanism 27.

When a game ball flowing down the game area PA enters any of the first starting port 51, the second starting port 52, the large winning opening 54, and the general winning opening 55 to 57, a prize is awarded according to the type of the winning opening. The ball is paid out to the upper ball plate 6 or the lower ball plate 7 by the prize ball payout unit 34. In the present embodiment, as the number of prize balls to be paid out when one game ball enters each prize opening (referred to as "unit prize ball number"), the first starting port 51 is "4" and the second. The starting opening 52 is set to "1", the general winning openings 55 to 57 are set to "3", and the large winning opening 54 is set to "15". The number of unit prize balls for each winning opening is not limited to that illustrated in the present embodiment, and other unit prize balls may be applied. For example, as the number of unit prize balls, the first starting port 51 may be "1" instead of "4". Further, the second starting port 52 may be "3" instead of "1". Further, the general winning openings 55 to 57 may be "5" instead of "3". Further, the large winning opening 54 may be "10 pieces" instead of "15 pieces".

When the game ball enters the first starting port 51 or the second starting port 52, a lottery random number value of the special symbol is acquired, and the random number value is temporarily stored as an operation holding ball of the special symbol up to a predetermined upper limit number. Then, when a predetermined start condition (a change start condition of a special symbol described later) is satisfied, a hit / fail determination, a symbol determination, and a variation pattern determination of the special symbol are performed on the lottery random number value related to the earliest operation holding ball. The special symbol is variablely displayed on the first special symbol display device 61 or the second special symbol display device 62, and the decorative symbol is variablely displayed on the effect display device 70 in an manner corresponding to this determination result. The variation display of the special symbol and the decorative symbol is synchronously stopped and displayed after the lapse of the variation time corresponding to the selected variation pattern.

When the first special symbol or the second special symbol is confirmed and displayed in a stop mode indicating a big hit, the game shifts to a special game (big hit game) that is more advantageous to the player than the normal game. In each round game (unit game) of this big hit game, an opening / closing operation is performed in which the big winning opening 54 is changed to the open state only once or a plurality of times. When a specified number of game balls enter the large winning opening 54, or when the opening time of the large winning opening 54 reaches the opening time limit, the round game being executed ends. Here, the stop mode of the decorative symbol indicating the big hit is, for example, an embodiment in which three types of symbols match. In the present embodiment, when the special symbol and the decorative symbol are confirmed and displayed in the stop mode indicating the jackpot, a plurality of round games (unit games) are executed as the jackpot game.

In the present embodiment, if a predetermined jackpot is won, the probability variation function of the special symbol may be activated from the end of the jackpot game until the number of fluctuations of the special symbol reaches the predetermined final number of times. When the probability fluctuation function of the special symbol is activated, the jackpot probability of the special symbol lottery shifts from the normal low probability state to the high probability state, so that a new jackpot (big hit game) will occur relatively early. Become. The probability fluctuation function of the special symbol may be continued until the next big hit occurs. Further, as the predetermined final number of times, "10000 times" may be set, which substantially corresponds to the number of fluctuation display times until the next big hit occurs.

In addition, after the jackpot game is completed, the function for shortening the fluctuation time of the special symbol may be activated in association with or independently of the function for changing the probability of the special symbol. When the special symbol variation time shortening function is activated, the average variation time of special symbols and decorative symbols tends to be shorter than usual, and the number of special symbol lottery per unit time is improved (big hit per unit time). Ease of acquisition can be increased).

Further, after the jackpot game is completed, the electric chew support function (also simply referred to as "electric support") may be activated in association with or independently of the function of shortening the fluctuation time of the special symbol. The electric chew support function enhances the ease of entering the second starting port 52 by operating the probability fluctuation function of the normal symbol, the fluctuation time shortening function of the normal symbol, and the opening extension function of the normal electric accessory 52c. It is a state (also referred to as a "easy-to-enter state"). When the probability fluctuation function of the normal symbol is activated, the winning probability of the normal symbol becomes higher than the normal state. When the function for shortening the fluctuation time of the normal symbol is activated, the fluctuation time of the normal symbol is shortened. When the opening extension function of the ordinary electric accessory 52c is activated, the opening time of the ordinary electric accessory 52c is extended from the normal state. In this easy-to-enter state, there is a high possibility that the number of fluctuations of the normal symbol per fixed time will increase more than usual, and the ease of entering the second starting port 52 will also increase. It also increases the possibility that the number of balls entered will increase. Therefore, by activating the electric chew support function, the chances of obtaining a prize ball by entering the second starting port 52 increase during that period, and as a result, it is possible to continue the game with almost no reduction in the number of balls held. Become. That is, the "base", which is the ratio of the number of prize balls to the number of shot balls of the game ball, becomes high. Hereinafter, the state in which the electric chew support function is operating is also referred to as a “high base state”, and the state in which the electric chew support function is not operating is also referred to as a “low base state”.

Next, the main feature configurations of the present embodiment will be described in order.

On the other hand, the hinge shaft (hinge hook 262) is used as a fulcrum to swing in the vertical direction (the front lid portion 261 can be opened and closed). By performing a two-step release operation on the lid member 260 (front lid portion 261 and rear lid portion 265) in this way, the entire lid member 260 is swung upward with respect to the unit case 201 to cause the unit case. The upper opening 202 of 201 can be opened. At this time, as shown in FIG. 21, since the lid member 260 has a two-fold structure, the rear lid portion 265 swings relative to the front lid portion 261 with the hinge 266 as a fulcrum. Since the entire lid member 260 can be displaced and opened in a desired folding posture (because the swing radius of the entire lid member 260 can be changed), the space required to open the lid member 260 is reduced. can do. Therefore, when the lid member 260 is opened (when the design sheets 281 to 283 are replaced), the lid member 260 collides with the glass frame 5 or the island equipment and cannot be opened or is damaged. Is possible. Then, by opening the lid member 260 upward in this way, the upper opening 202 of the unit case 201 is opened, and the design sheets 281 to 283 are extracted from the sheet accommodating portions 213, 221, 223 of the unit case 201. Can be done. After taking out the design sheets 281 to 283 from the unit case 201 in this way, by inserting the new design sheet into each sheet accommodating section 213,221,223, the new design sheet is inserted into each sheet accommodating section 213,221,223. It is housed and the new design sheet becomes visible from the outside through the outer window portion 211b, the inner upper window portion 220b and the inner lower window portion 220c of the unit case 201. After replacing the design sheets 281 to 283 in this way, the lid member 260 is swung downward to re-engage the lock claw 267a of the lid member 260 and the locked portion 254 of the right unit case 201. The lid member 260 is connected and fixed in a state where the upper opening 202 of the right unit case 201 is closed.

As a locking mechanism between the right unit case 201 and the lid member 260, not only the lock claw 267a is provided at the rear end of the lid member 260, but also the movable claw 263a is provided at the center of the lid member 260. When the lid member 260 has a bi-fold structure consisting of a front lid portion 261 and a rear lid portion 265, only the front end portion (hinge hook 262) and the rear end portion (lock claw 267a) of the lid member 260 are united. Just by connecting to the case 201 (only by supporting two points by both front and rear ends), the middle part of the lid member 260 (chome) with the front end and the rear end of the lid member 260 as fulcrums due to the action of the cover member 260. This is because the portion (No. 266) can be lifted upward, and there is a possibility that fraudulent acts may be performed by inserting fraudulent tools such as a piano wire or a wire through the gap generated in the lifted portion. Therefore, in the present embodiment, a locking mechanism by the movable claw 263a is also provided in the middle portion of the lid member 260, and the lid member 260 is supported by three points of the front end portion, the center portion, and the rear end portion of the lid member 260.

Next, a procedure for removing the right decorative unit 200 from the glass frame 5 will be described. First, in order to remove the right decorative unit 200 from the glass frame 5, the glass frame 5 is opened with respect to the front frame 2. Subsequently, a predetermined release operation is performed from the rear surface side of the glass frame 5, and the upper decoration unit 300 is removed from the front surface of the glass frame 5. When the upper decorative unit 300 is removed from the glass frame 5, the right unit removal lever 272 provided on the right decorative unit 200 is exposed and can be accessed. Next, the right unit removal lever 272 is operated to disengage the upper hook portion 271 from the upper hook receiving groove 516b of the glass frame 5. As a result, the locked state between the right decorative unit 200 and the glass frame 5 is released. Then, the upper portion of the right decorative unit 200 is swung (tilted) forward, and the lower mounting protrusion 231 provided at the lower end of the right decorative unit 200 is removed from the lower support groove 516a of the glass frame 5. do. As a result, the right decorative unit 200 can be removed from the front side of the glass frame 5.

As described above, according to the present embodiment, the lid member 260 is formed into a two-piece structure (bi-folding structure) in which the lid member 260 is connected by a hinge 266, and the lid member 260 is folded into a desired posture when the design sheets 281 to 283 are replaced. By making it possible to open and close the lid member 260, the space required to open and close the lid member 260 can be reduced. Therefore, when the lid member 260 is opened and closed, the lid member 260 collides with a structure such as a glass frame 5 or island equipment and is damaged. Can be prevented. In addition, the plurality of design sheets 281 to 283 are individually identified by assigning unique identification symbols according to the model (model) of the game board 20, the type of the decorative unit 12, the accommodation position, and the like. , Design sheets 281 to 283 of the wrong model (model) will not be shipped, and design sheets 281 to 283 of different models (model) will not be mixed in the decoration unit 12, and the design sheets 281 to 283 will be replaced. And can be easily managed. Furthermore, for example, when manufacturing a model that uses the same motif (character or title) but has a different jackpot probability (model with different specifications), one of the multiple design sheets is used in common and the other is redesigned. As a result, it is possible to reduce the development man-hours and manufacturing costs of design sheets (it becomes unnecessary to produce block copy of all design sheets from scratch for each model). As an example, when manufacturing a model with different specifications (so-called series machine) from this model, the first design sheet 281 and the second design sheet 282 are commonly used, and only the third design sheet 283 is used as a new design sheet. You may replace it. In the case of models (series machines) having different specifications, the above board symbols may be the same, or the board symbols may be different. Further, in the case of a model (series machine) having different specifications, the above board symbol may be used as a related symbol. For example, "PM04" may be used as a common symbol for multiple models having different specifications, and "PM04" may be used according to the specifications. Individual symbols such as "A", "B", and "C" may be added ("PM04A", "PM04B", and "PM04C" may be set for each model as the board symbols of the series machine). Further, the above sheet numbers may be set according to the arrangement of the design sheets 281 to 283. For example, the design sheet arranged on the outside (right side surface) of the right decoration unit 200 is "DY1", and the right decoration unit. By assigning "DY2" to the design sheet placed on the inner upper part (upper left side) of the 200, and "DY3" to the design sheet placed on the inner lower part (lower left side) of the right decoration unit 200, each The layout of the design sheet may be easy to understand.

[Glass frame fraud prevention structure]
Next, the fraud prevention structure of the glass frame 5 will be described with reference to FIG. 37 in addition to the above FIGS. 12, 13, 14 and the like.

It is arranged so as to surround the peripheral edge of the opening end of the operation port 517. That is, the first fraud prevention rib 518 is a peripheral wall portion that surrounds the periphery of the lever operation port 517 on the rear surface side of the door frame member 510. As described above, the lever operation port 517 is inserted with a release lever 255 provided so as to project toward the rear surface side of the right decorative unit 200, and the first fraud prevention rib 518 is provided in a state where the glass frame 5 is opened. It is possible to operate the release lever 255 from the inside of the lever operation port 517. The first fraud prevention rib 518 protrudes from the rear surface of the door frame member 510 toward the front surface side of the front frame 2 with a predetermined protrusion amount, and the glass frame 5 is closed with respect to the front frame 2. In the state, it is close to the front surface of the front frame 2. Needless to say, it is preferable that the gap between the rear end portion of the first fraud prevention rib 518 and the front end portion of the front frame 2 is as small as possible (that is, both may be in contact with each other).

The second fraud prevention rib 529 extends vertically along the right edge of the glass frame 522 and is continuously formed. The second fraud prevention rib 529 is formed so as to project from the right edge portion (right side portion) of the glass frame 522 toward the right outside, and the reinforcing sheet metal 512 fixed to the door frame member 510 is formed on the front surface side thereof. Are arranged facing each other in the front-rear direction. The reinforcing sheet metal 512 is attached along the right end portion (open end portion) on the rear surface side of the door frame member 510 to reinforce the strength of the door frame member 510 and a part of the locking device 4 (key receiving side).

On the tip surface (rear end surface) of the side sheet metal portion 514, a notch portion 514a notched (relief processed) in the plate width direction (front-back direction) of the side surface sheet metal portion 514 is formed. The front side of the second fraud prevention rib 529 is in contact with the notch 514a (or is close to the cutout portion 514a with a very small gap). Further, the second fraud prevention rib 529 protrudes to the right side (open end side of the glass frame 5) from the side sheet metal portion 514 (notch portion 514a), and the second fraud prevention rib 529 and the side sheet metal portion 514 ( The cutouts 514a) overlap (overlap) each other when viewed from the front-rear direction.

Subsequently, the operation of the fraud prevention structure of the glass frame 5 will be described. Since the gaming machine PM of the present embodiment is provided with a heavy object called a right decorative unit 200 in the upper right portion on the front side of the glass frame 5, the upper right portion of the glass frame 5 (open end of the glass frame 5) is provided by the weight. Since the upper part on the side is tilted forward, there is a possibility that an unintended gap may be generated in the connection portion or the joint of each component arranged in the upper right portion of the glass frame 5. Therefore, in order to eliminate the harmful effects of attaching the right decorative unit 200 to the upper right portion on the front side of the glass frame 5, strict fraud prevention measures (two fraud prevention ribs 518 and 529 are used) on the upper right portion of the glass frame 5. Fraud prevention measures) are in place.

First, a wire or a piano is formed from a slight gap between the rear surface of the right decorative unit 200 and the front surface of the glass frame 5, or a slight gap between the right unit case 201 of the right decorative unit 200 and the lid member 260. When an illegal tool such as a wire is inserted and the illegal tool is inserted into the lever operation port 517 of the glass frame 5 toward the inside of the game machine PM, the entire circumference of the opening end of the lever insertion port 517 is surrounded. Since the first fraud prevention rib 518 is formed in the first fraud prevention rib 518, the presence of the first fraud prevention rib 518 makes it impossible for the fraudulent tool to invade any more, and unauthorized access to the game area PA of the game board 20 is performed. become unable.

On the other hand, when an illegal tool such as a wire or a piano wire is inserted through the gap of the window portion 5a of the glass frame 5 (the gap between the window 511 of the door frame member 510 and the glass plate 521 of the glass unit 520), the glass frame 522 Since the second fraud prevention rib 529 formed along the right end edge of the glass frame 5 extends toward the open end side (locking device 4 side) of the glass frame 5, the fraudulent tool is inserted toward the locking device 4. Also, it is not possible to invade the second fraud prevention rib 529 any more, and it is possible to prevent fraudulent acts of illegally operating the locking device 4 to open the glass frame 5. In particular, in the present embodiment, the second fraud prevention rib 529 abuts on the notch 514a of the reinforcing sheet metal 512, and the second fraud prevention rib 529 is closer to the open end side than the side surface metal portion 514 of the reinforcing sheet metal 514. Since it is protruding, it is possible to cut off the intrusion route of the fraudulent tool toward the locking device 4, thereby further enhancing the fraud prevention effect.

As described above, according to the present embodiment, the fraudulent tool is inserted from the fragile portion (gap) in the upper right portion of the glass frame 5 which may be caused by attaching the right decorative unit 200 of a heavy object to the upper right portion of the front surface of the glass frame 5. Even if it does, fraud prevention ribs 518,529 are provided on the intrusion route from the gap that is the fragile part (open end around the release lever 255, right edge of the glass unit 520), which is fraudulent. Since the fraud prevention ribs 518 and 529 can prevent further intrusion of the tool, it effectively prevents unauthorized operations (illegal acts) performed on the game board 20 (game area PA) and the locking device 4. It becomes possible to do.

The front and back are separated. The wide passage 651 has a passage width equivalent to that of about two game balls in the front-rear direction, and is formed so as to incline downward from the left side to the right side. Therefore, the game ball that has fallen from the rear surface side of the game board 20 into the wide passage 651 flows down toward the first front passage 652 provided on the right side thereof.

The first front passage 652 is formed by being continuously connected to the rear row side of the right end portion of the wide passage 651. The first front passage 652 is formed at the central upper end portion of the first passage forming member 610, and the front passage wall portion 611 formed on the upper right side of the first passage forming member 610 and the second passage forming member 620. The front and rear are separated from the left rear passage wall portion 621. The first front passage 652 has a passage width equivalent to that of about one game ball in the front-rear direction, and is formed so as to incline downward from the left side to the right side. Therefore, the game ball that has reached the first front passage 652 flows down toward the connecting passage 654 provided on the right side thereof.

The second front passage 653 is formed by being continuously connected to the right end portion of the connecting passage 654. The second front passage 653 is formed at the upper right upper end of the first passage forming member 610, and is partitioned forward by the front passage wall portion 611 of the first passage forming member 610. The second front passage 653 has a passage width equivalent to that of about one game ball in the front-rear direction, and is formed so as to incline downward from the right side to the left side. Therefore, the game ball that has reached the second front passage 653 flows down toward the connecting passage 654 provided on the left side thereof.

The connecting passage 654 is formed by being continuously connected to the right end portion of the first front passage 652 and the left end portion of the second front passage 653. The connecting passage 654 is formed at the central upper end portion of the first passage forming member 610, and is partitioned forward by the front passage wall portion 611 of the first passage forming member 610, and the rear passage portion 655 is behind the front passage wall portion 611. Is facing. The connecting passage 654 has a passage width equivalent to that of about one game ball in the front-rear direction, and is formed so as to extend substantially horizontally to the left and right and to incline downward toward the rear. Therefore, the game ball that has reached the connecting passage 654 flows down toward the rear passage 655 provided behind the connecting passage 654.

The rear passage 655 is formed so as to extend to the left and right at a height position lower than those passages 651 to 654 on the rear side of the above-mentioned single row passages 651 to 654. The rear passage 655 is formed on the front side of the second passage forming member 620, and is partitioned rearward by the right rear passage wall portion 622 of the second passage forming member 620. The rear passage 655 has a passage width equivalent to that of about one game ball in the front-rear direction, and is formed so as to incline downward from the right side to the left side. Therefore, the game ball that has reached the rear passage 655 flows down toward the meandering passage 656 provided on the left side thereof.

The meandering passage 656 is formed by being continuously connected to the left end portion of the rear passage 655. The meandering passage 656 straddles between the first passage forming member 610 and the second passage forming member 620, and a front inclined surface that inclines forward and a rear inclined surface that inclines downward to the rear pass through a folded portion. It is formed in a continuous meandering shape. That is, this meandering passage 656 is a passage for coasting the game ball flowing down from the right side to the left side in the front-rear direction. A strip-shaped static electricity removing sheet metal 660 is attached to the intermediate passage portion 662 formed between the upstream portion of the meandering passage 656 and the downstream portion of the rear passage 655. The static electricity removing sheet metal 660 is made of a metal such as stainless spring steel, and is formed into a desired shape by punching and bending a thin metal flat plate. At the lower part of the static electricity removing sheet metal 660, a mounting plate portion 661 screwed to the second passage forming member 620 is formed. The upper surface of the static electricity removing sheet metal 661 forms a passage surface from the downstream portion of the rear passage 655 to the upstream portion of the meandering passage 656, and is in contact with the game ball flowing down the passage surface to charge the game ball. Remove static electricity. The static electricity removing sheet metal 660 is connected to the ground plate (not shown) of the locking device 4 via a ground wire or the like. The game ball that has reached the downstream end of the meandering passage 656 flows down to the discharge passage 683 provided below the game ball.

The discharge passage 683 is formed by being continuously connected to the rear end portion of the left side 670 of the meandering passage 656. The discharge passage 683 is formed inside a sensor cassette 670 attached to and detached from the second passage forming member 620. The details of this sensor cassette 670 will be described later. The discharge passage 683 has a passage width equivalent to that of about one game ball in the front-rear direction, and is formed so as to incline downward from the left side to the right side. At the entrance of the discharge passage 683, a gamed ball detection switch (gamed ball detection sensor) 690 for detecting a game ball (gamed ball) flowing down the discharge passage 683 is arranged. The details of the gamed ball detection switch 690 will be described later.

At the end of the discharge passage 683, a game ball discharge port 685 that opens downward is formed. Therefore, the game ball flowing down the discharge passage 683 is discharged to the outside of the machine (outside the game machine) from the game ball discharge port 685 at the downstream end thereof, and is finally collected on the game island (game hall facility).

Subsequently, the configuration of the sensor cassette 670 will be described. In FIG. 25, the sensor cassette 670 is arranged on the first passage forming member 610 side for convenience of explanation, but in reality, as shown in FIG. 24, the sensor cassette 670 is on the second passage forming member 620 side. It is attached to.

The sensor cassette 670 includes a box-shaped sensor case 680 having an L-shape in front view, and a gamed ball detection switch 690 held in the sensor case 680. The sensor cassette 670 is detachably attached to a cassette accommodating portion 630 formed in the lower center of the front surface of the second passage forming member 620. The cassette accommodating portion 630 is open forward and downward, and a partition wall for restricting the forward / backward movement of the sensor cassette 670 mounted on the cassette accommodating portion 630 by closing a part of the front opening at the upper right portion thereof. 631 is formed extending in the vertical plane. Therefore, the sensor cassette 670 can be attached to and detached from the cassette accommodating portion 630 only in the vertical direction. That is, the sensor cassette 670 is restricted from being attached / detached in the front-rear direction due to the presence of the partition wall 631 of the cassette accommodating portion 630.

The sensor case 680 is composed of a front case 681 and a rear case 682, and the above-mentioned discharge passage 683 is defined between the front case 681 and the rear case 682. A game ball introduction port 684 for introducing a game ball (gamed ball) is opened in the vertical direction at the upper end of the sensor case 680, and a game ball (gamed ball) is discharged at the lower end of the sensor case 680. The above-mentioned game ball discharge port 685 for this purpose is opened in the vertical direction. Immediately below the game ball introduction port 684 of the sensor case 680, a sensor holding groove 686 for mounting the gamed ball detection switch 690 straddles between the rear surface of the front case 681 and the front surface of the rear surface case 682. ing.

The front case 681 is formed in a substantially box shape that opens rearward using a transparent synthetic resin material. A tongue piece portion 681a projecting downward is formed in the lower portion of the front case 681, and a screw for inserting a screw for fixing the sensor case 680 to the second passage forming member 620 is inserted in the tongue piece portion 681a. The insertion hole 681b is penetrated. In addition, the front case 6
A plurality of step grooves 681c extending in the front-rear direction are recessed in the outer peripheral wall portion of 81, and a wedge-shaped outer peripheral protrusion 681d is formed on the bottom surface of the groove of the step groove 681c.

The rear case 682 is formed in a substantially box shape that opens forward using a conductive material. As the conductive material, for example, a conductive resin material mixed with carbon fiber (carbon fiber), a conductive gold-plated material, or the like is preferably used. By giving conductivity to one of the two-divided sensor cases 680 (rear surface case 682) in this way, a game ball flowing down the discharge passage 683 formed between the front case 681 and the rear surface case 682. The static electricity charged on the (gamed ball) can be effectively removed. A metal flat plate-shaped conductive plate 632 is fixed to the front wall of the cassette accommodating portion 630, and the rear case 682 and the conductive plate 632 are moved back and forth while the sensor cassette 670 is attached to the cassette accommodating portion 630. The contact is made and static electricity is discharged from the rear case 682 to the conductive plate 632. The conductive plate 632 is connected to the ground plate (not shown) of the locking device 4 in the same manner as the static electricity removing sheet metal 660 described above.

Further, on the outer peripheral wall portion of the rear surface case 682, a substantially annular outer peripheral locking portion 682a projecting forward is formed at a position corresponding to the plurality of step grooves 681c formed in the front case 681. The outer peripheral locking portion 682a is fitted in the front-rear direction with respect to the step groove 681c of the front case 681, and is further engageable with the outer peripheral protrusion 681d formed on the groove bottom surface of the step groove 681c. .. That is, the front case 681 and the rear case 682 are connected and integrated by superimposing the front case 681 and the rear case 682 in the front-rear direction and engaging the outer peripheral locking portion 682a and the outer peripheral protrusion 681d. The sensor case 680 is assembled.

The gamed ball detection switch 690 is a passage type sensor (for example, an electromagnetic induction type proximity sensor) that detects the passage of the game ball (gamed ball), and is a game ball (gamed ball) that flows down the gamed discharge passage 650. Count the real number of. When the game ball (gamed ball) passes through the detection port, the game ball detection switch 690 changes the impedance of a coil (not shown) arranged around the detection port, so that the game ball is a metal object. Detects that (gamed ball) has passed. The gamed ball detection switch 690 is attached to the sensor case 680 by being fitted into a sensor holding groove 686 formed so as to straddle between the rear surface of the front case 681 and the front surface of the rear surface case 682. The detection port of the game ball detection switch 690 is arranged so as to face the game ball introduction port 684 of the sensor case 680 in the vertical direction, and the inside of the sensor case 680 (discharge passage 683) from the game ball introduction port 684. The game ball (gamed ball) introduced in is passed through the detection port of the gamed ball detection switch 690.

In order to attach the sensor cassette 670 having such a configuration to the second passage forming member 620, the sensor cassette 670 is placed below the second passage forming member 620 with the game ball introduction port 684 of the sensor cassette 670 facing straight up. It is fitted into the cassette accommodating portion 630. Subsequently, a screw (not shown) is inserted into the screw insertion hole 681b of the cassette case 680, and this is screwed into the screw hole (not shown) of the second passage forming member 620, whereby the sensor cassette 670 is second. It is mounted in the cassette accommodating portion 630 of the passage forming member 620. When the sensor cassette 670 is attached to the cassette accommodating portion 630, the game ball introduction port 684 of the sensor cassette 630 and the downstream end of the meandering passage 656 are aligned in the vertical direction, and the game ball reaching the downstream end of the meandering passage 656 ( The gamed ball) flows down to the discharge passage 683 via the game ball introduction port 684 of the sensor cassette 670.

On the other hand, in order to remove the sensor cassette 670 from the second passage forming member 620, a screw (not shown) is removed from the screw hole (not shown) of the second passage forming member 620, and the sensor cassette 670 is lowered from the cassette accommodating portion 630. The sensor cassette 670 is removed from the second passage forming member 620 by pulling it toward. At this time, since the sensor cassette 670 is removed from the cassette accommodating portion 630 in the downward direction, even if the game ball is clogged near the detection port of the gamed ball detection switch 690, the game ball with respect to the detection port is used. Since the passing direction (downward direction) of the sensor cassette 670 coincides with the attachment / detachment direction (downward direction) of the sensor cassette 670, the sensor cassette 670 can be easily removed along the passing direction (flowing direction) of the game ball. That is, when the configuration in which the detection sensor (passing sensor) is removed in the horizontal direction is adopted as in the conventional case, the flow direction (downward direction) of the game ball and the attachment / detachment direction (horizontal direction) of the detection sensor are orthogonal to each other. Therefore, if the detection sensor is forcibly removed when the detection sensor is clogged near the detection port, the clogged game ball will be sandwiched between the detection sensor and the passage wall, so-called. Although there was a problem that ball biting occurred, in the present embodiment, the presence of the partition wall 631 of the cassette accommodating portion 630 restricts the removal of the gamed ball detection switch 690 in the horizontal direction (forward direction). , The problem that ball biting occurs when the sensor cassette 670 is removed is prevented.

Further, by providing the meandering passage 656 in front of the gamed ball detection sensor 690, the flow speed of the game ball is reduced in the process of flowing down the meandering path 656, and the game ball passes through the gamed ball detection sensor 690 on the downstream side thereof. When the game is played, the momentum (flow speed) of the game ball is sufficiently suppressed, so that false detection (detection failure) due to wear or chattering of the detection part of the game ball detection switch 690 is prevented and the game is completed. It is possible to stabilize the detection accuracy of the game ball by the ball detection sensor 690.

In addition, by forming the passage surface on the downstream side of the static eliminating sheet metal 660 as a part of the meandering passage 656, a temporary stop of the game ball occurs when flowing down the meandering passage 656, and the following is caused accordingly. Since it takes a long time for the game ball to flow down the upper surface of the static electricity removing sheet metal 660 (that is, the contact time between the game ball and the static electricity removing sheet metal 660 becomes long), the static electricity charged on the game ball is more reliably discharged to the outside. It will be possible to escape. Further, if the static electricity removing sheet metal is provided in the meandering passage 656, the shape of the static electricity removing sheet metal becomes complicated, but if the static electricity removing sheet metal is provided on the upstream side of the meandering passage 656, the shape of the static electricity removing sheet metal is simplified. Can be (easy to manufacture and install static eliminator sheet metal).

As described above, according to the present embodiment, the flow direction (downward) of the game ball when passing through the gamed ball detection switch 690 and the attachment / detachment direction (downward) of the sensor cassette 670 are the same direction. Even if the ball of the game ball is clogged near the detection port of the gamed ball detection switch 690, the sensor cassette 670 (gamed ball detection switch 690) can be easily removed from the second passage forming member 620 without biting the ball. This makes it possible to improve the maintainability of the gaming machine PM.

Since the back fixing tool 590A and the bottom surface fixing tool 590B have basically the same structure, in the following description, when it is not necessary to particularly distinguish between the back surface fixing tool 590A and the bottom surface fixing tool 590B, These are collectively collectively referred to simply as "fixture 590".

The pedestal portion 580 is formed to have a predetermined thickness in the vertical direction, and protrudes forward from the lower end of the frame main body 570. The upper surface of the pedestal portion 580 is formed as a seat surface on which the effect operation unit 700 is placed. A pair of left and right fixture holding holes (not shown) are formed through the pedestal portion 580 in the vertical direction, and the bottom fixture 590B is slid vertically in the fixture holding holes (not shown). It is mounted freely. The bottom surface fixative 590B is formed in an axial shape extending in the vertical direction, and has a predetermined reference rotation position (rotation position of 0 degrees around the axis) in a state of being inserted into a fixture holding hole (not shown). It is arranged so as to be reciprocally rotatable between and the maximum rotation position (rotation position of 90 degrees around the axis). That is, the bottom surface fixative 590B is rotatable within a range of about 90 degrees in a fixative holding hole (not shown). Further, in the fixture holding hole (not shown), a coil spring 599b (see FIG. 32) for constantly urging the bottom fixture 590B downward is arranged.

As shown in FIG. 34, a substantially flat plate-shaped movable plate 585 parallel to the upper surface is slidably attached to the upper surface side of the pedestal portion 580 in the front-rear direction. A pair of left and right lock grooves 586, which are punched in the plate thickness direction (vertical direction) and opened forward, are provided on the tip end side of the movable plate 585. Each lock groove 586 is formed in the shape of a spline groove in which irregularities (peaks and valleys) are alternately and continuously formed in the circumferential direction. The mountain portion (large diameter portion) and the valley portion (small diameter portion) of the lock groove 586 are formed at intervals of 90 degrees in the circumferential direction. The lock groove 586 has a groove shape corresponding to the outer shape of the locked shaft portion 593, which will be described later, formed in the intermediate portion in the axial direction of the fixture 590 (bottom fixture 590B), and is locked. It is configured so that it can be fitted (engaged) with the shaft portion 593 in the front-rear direction. Further, the movable plate 585 is formed with four elongated hole portions 587 that penetrate in the plate thickness direction (vertical direction) and extend in the front-rear direction, and the elongated hole portions 587 are provided in the pedestal portion 580. The cylindrical pin portion 582 is inserted.

In the present embodiment, the position where the pin portion 582 abuts on the rear end of the long hole portion 587 is the restraint position (front end position), and the position where the pin portion 582 abuts on the front end of the long hole portion 587 is the release position (rear end position). Is. Further, the movable plate 585 is mechanically connected to the slide operation portion 588 provided on the rear surface side of the glass frame 5 via a slide link mechanism (not shown), and when the slide operation portion 588 is pushed forward. The movable plate 585 is configured to slide and displace forward (locked position), and when the slide operation unit 588 is pulled back to the rear, the movable plate 585 slides and displaces rearward (unlocked position). A coil spring 589 is interposed between the slide operation portion 588 and the pedestal portion 580, and the slide operation portion 588 is constantly urged rearward by receiving the elastic force of the coil spring 589. Therefore, when the glass frame 5 is opened, the slide operation portion 588 is pushed backward by the urging force of the coil spring 588, so that the movable plate 585 slides backward and is held in the unlocked position. On the other hand, when the glass frame 5 is closed, the slide operation portion 588 abuts on the front surface portion of the front frame 2 and is pushed forward, so that the movable plate 585 slides forward and is held in the locked position. become.

On the other hand, in the frame main body 570 and the door frame member 510, as shown in FIGS. 32, 35 and 36, a pair of left and right fixture holding holes (shown) straddle the frame main body 570 and the door frame member 510. The back fixture 590A is movably attached to the fixture holding hole (not shown) in the front-rear direction in a retaining state. The back fixture 590A is formed in an axial shape extending in the front-rear direction, and has a predetermined reference rotation position (rotation position of 0 degrees around the axis) in a state of being inserted into a fixture holding hole (not shown). It is arranged so as to be reciprocally rotatable between and the maximum rotation position (rotation position of 90 degrees around the axis). That is, the back fixture 590A is rotatable within a range of about 90 degrees in a fixing holding hole (not shown). Further, a coil spring 599a (see FIG. 32) for constantly urging the back fixture 590A toward the rear is arranged in the fixture holding hole (not shown).

Here, as shown in FIGS. 35 and 36, on the rear surface side of the glass frame 5, the rear fixture 590A is placed from the rear at the arrangement position of the rear fixture 590A on the right side of the left and right rear fixtures 590A. The frame relay board unit 980 is detachably attached so as to cover it. The frame relay board unit 980 is made of a transparent resin that houses the frame relay board 981 electrically connected to the frame lamp 11 provided on the glass frame 5, the effect operation unit 700, and the like, and the frame relay board 981. It is composed of the board case 982 of the above, and is screwed to the board mounting portion 519 formed on the rear surface side of the door frame member 510. The frame relay board case 982 is composed of a case main body 983 to which the frame relay board 981 is fixed, and a case lid 984 that is detachably attached to the case main body 983 and covers the rear surface side of the frame relay board 983. When the frame relay board unit 980 is attached to the board mounting portion 519 of the glass frame 5, the right rear fixture 590A of the left and right rear fixtures 590A is concealed by the frame relay board unit 980. As a result, even if the glass frame 5 is opened, the right rear fixture 590A of the left and right rear fixtures 590A cannot be accessed unless the frame relay board unit 980 is removed.

Each fixture 590 (back surface fixture 590A, bottom surface fixture 590B) is a substantially columnar rod member extending in the axial direction. At the tip of each fixture 590 in the axial direction, a shaft tip portion 591 that can be inserted into the insertion holes 753a and 754a of the unit base 740 described later is formed. Further, a rib-shaped operation grip portion 592 that can be gripped by a finger is formed at a base end portion in the axial direction of the fixture 590. Further, a locked shaft portion 593 having a cross-sectional shape (spline shape) corresponding to the lock groove 586 of the movable plate 585 is formed in the intermediate portion in the axial direction of the fixture 590, and is formed in front of and behind the lock groove 586. It is configured so that it can be fitted (engaged) unevenly in the direction. When the locked shaft portion 593 of the fixing tool 590 (bottom fixing tool 590B) is unevenly fitted with the lock groove 586 of the movable plate 585, the fixing tool 590 (bottom fixing tool 590B) cannot rotate around the axis (bottom fixing). The rotation operation of the tool 590B is restricted). In the present embodiment, by using such four fixtures 590, the effect operation unit 700 is connected and fixed to the lower frame 560 of the glass frame 5.

As shown in FIGS. 28 and 30, the effect operation unit 700 is mainly composed of an effect lever 701 operated by a player and a unit base 740 that supports the effect lever 710 so as to be tiltable in the front-rear direction. .. The effect operation unit 700 is configured as a combined operation device that enables a player to operate a lever (tilting operation) and a button (pressing operation).

The effect lever 701 receives an input operation by the player and receives the power of the motor 731 described later to perform an effect operation (rotational operation and reciprocating operation), and the effect operation (rotational operation and reciprocating operation) of the lever accessory 710. (Reciprocating operation) It is configured to have an accessory support member 720 that supports it so as to be possible. The effect lever 701 is provided with an effect lever LED 702 (see FIG. 31) that causes the entire effect lever 710 to emit light.

As shown in FIGS. 28 and 29, the lever accessory 710 is a movable member (operation member) having a shape imitating the face of an alien. At the upper end of the lever accessory 710, an effect button 711 that can be pressed by the player is provided. The effect button 711 has a general push button structure, and is a press detection sensor 712 (see FIG. 31) that detects that the effect button 711 is pressed by a player, and an effect button LED 713 that emits light of the effect button 711. (See FIG. 31). At the lower end of the lever accessory 710, a sphere 714 constituting a ball joint described later is provided.

The accessory support member 720 is formed in the shape of a hollow jar having a circular opening above, and the lower portion of the lever accessory 710 is received and held in the hollow portion. A lever detection piece 721 for detecting the tilt position of the effect lever 710 by the initial tilt position sensor 792 and the maximum tilt position sensor 793 (see FIG. 31), which will be described later, is formed so as to protrude from the lower right side of the accessory support member 720. There is. Further, a first drive mechanism 730 for rotating the lever accessory 710 is attached to the inside of the accessory support member 720.

As shown in FIG. 29, the first drive mechanism 730 includes a motor 731 as a drive source and a gear mechanism 732 that transmits the drive force of the motor 731 to the lever accessory 710. The motor 731 can be rotationally driven in both forward and reverse directions based on the drive pulse signal from the effect control board 920. The gear mechanism 732 includes a motor gear 733 directly connected to the output shaft of the motor 731, a reduction gear 734 that meshes with the motor gear, and an output gear 735 that meshes with the reduction gear, and each gear 733 to 735 is a gear support plate. It is configured to be rotatably attached to the 739. The reduction gear 734 is a two-stage gear in which a large-diameter gear 734a and a small-diameter gear 734b are coaxially formed. The large-diameter gear 734a meshes with the motor gear 733, and the small-diameter gear 734b meshes with the output gear 735. A cylindrical portion 736 projecting upward is coaxially and integrally formed on the output gear 735. Inside the cylindrical portion 736, a ball receiving seat 737, which is a substantially spherical concave surface, is opened upward. The ball receiving seat 737 is configured to be rotatable integrally with the output shaft 735 with the center axis X of the output gear 735 as the center of rotation. A sphere 714 of the lever accessory 710 is fitted in the ball receiving seat 737, and a ball joint (spherical pair even) is formed by a combination of the sphere 714 of the lever accessory 710 and the ball receiving seat 737 of the output gear 735. As a result, the lever accessory 710 can swing in any direction (three-dimensionally) with the ball joint as a fulcrum. When the motor 731 is rotationally driven, this rotational driving force is transmitted to the lever accessory 710 via the gear mechanism 732 and the ball joint mechanism so that the lever accessory 710 draws a circle or an arc with the central axis X as the center of rotation. Rotate. At this time, by switching the rotation drive direction of the motor 731 to the forward rotation direction or the reverse rotation direction, the rotation direction of the lever accessory 710 can be switched to the clockwise direction or the counterclockwise direction in conjunction with the switching. The details of the effect operation (rotational operation, reciprocating operation) of the lever accessory 710 will be described later.

The accessory support member 720 has an upper rotation reference position sensor 791 (see FIG. 31) that detects that the rotation position of the lever accessory 710 is at the upper rotation reference position, which is the upper end position on the rotation circumference.
Is provided. As the upper rotation reference position sensor 791, for example, a photosensor having a light projecting unit that emits light and a light receiving unit that receives light from the light projecting unit is suitable. The upper rotation reference position sensor 791 is set at a position (12 o'clock position of the clock) where the lever accessory 710 is most displaced toward the game machine PM on the rotation circumference of the lever accessory 710. In the present embodiment, the lever accessory 710 can rotate in the clockwise direction or the counterclockwise direction with the upper rotation reference position (the 12 o'clock position of the clock) as the starting point. As a result, the number of rotations and the number of reciprocations (number of vibrations) in the effect operation (rotational operation and reciprocating operation) of the lever accessory 710 are detected based on the number of times the lever accessory 710 reaches or passes the upper rotation reference position. It has become so. The detection signal of the upper rotation reference position sensor 791 is input to the effect control board 920. In this embodiment, when the lever accessory 710 is in the upper rotation reference position or when the lever accessory 710 is in the lower rotation reference position, the player can tilt the effect lever 701 backward. ing. The lower rotation reference position is set to a position (6 o'clock position of the clock) in which the lever accessory 710 is most displaced toward the player on the rotation circumference of the lever accessory 710. That is, the lower rotation reference position is a position in which the lever accessory 710 is rotated 180 degrees clockwise or counterclockwise from the upper rotation reference position. In this embodiment, the lever accessory 710 is not detected at the lower rotation reference position, but the position detection sensor (lower rotation reference position sensor) for detecting that the lever accessory 710 is at the lower rotation reference position. ) May be provided.

As shown in FIG. 28, the unit base 740 includes a base body 750 that supports the effect lever 701 so as to be tiltable in the front-rear direction, and a decorative frame body 770 that is attached to the base body 750 and surrounds the effect lever 701. It is composed of.

The base body 750 has a bottom plate 751 and a standing plate 752 and is formed in a substantially L shape, and is detachably attached to the lower frame 560 of the glass frame 5. On the upper surface side of the bottom plate 751, a pair of bottom surface locking receiving portions 753 are provided so as to project upward, and a bottom surface insertion hole 753a is formed through the bottom surface locking receiving portion 753 substantially in the center in the vertical direction. .. A pair of back surface locking receiving portions 754 are provided on the front surface side of the standing plate 752 so as to project forward, and a back surface insertion hole 754a is formed through the back surface locking receiving portion 754 substantially in the center in the front-rear direction. There is. The bottom surface insertion hole 753a and the back surface insertion hole 754a are formed in the same hole shape (cross-sectional shape), and the shaft tip portion 591 of each fixture 590 is configured to be able to be inserted in the axial direction.

Further, an elongated rod-shaped support shaft portion 755 extending in the left-right direction is erected on the upper end side of the standing plate 751, and the support shaft portion 755 is fitted into the bearing portion 722 of the accessory support member 720. The effect lever 701 is supported so as to be tiltable (swingable) in the front-rear direction with respect to the base body 750 around the support shaft portion 755. The support shaft portion 755 is provided with a return spring 756 that urges the effect lever 701 upward (initial tilt position). The return spring 756 is a torsion spring (torsion spring), one end side thereof is locked to the standing plate 752, and the other end side is locked to the effect lever 701. As a result, the effect lever 701 receives an elastic force from the return spring 765 and is constantly urged upward (initial tilt position described later).

The base body 750 is provided with a second drive mechanism 760 that tilts the effect lever 701 in the front-rear direction. The second drive mechanism 760 includes a motor 761 as a drive source and a tilting mechanism 762 that transmits the driving force (rotational force) of the motor 761 to the effect lever 701. The motor 761 can be rotationally driven in both forward and reverse directions based on the drive pulse signal from the effect control board 920. The tilting mechanism 762 is configured to include mechanical parts such as gears and cams, and converts the rotational motion of the motor 761 into a tilting motion (swing motion) around the support shaft portion 755 of the effect lever 701.

The decorative frame body 770 is composed of an upper decorative portion 771 and a lower decorative portion 772, and the upper decorative portion and the lower decorative portion are combined with each other to form an annular frame body. The decorative frame 770 is provided with a lever insertion opening 773 formed in a substantially circular shape corresponding to the operating range of the effect lever 701. The decorative frame body 770 is screwed and attached to the front side of the base body 750.

The base body 750 has an initial tilt position sensor 792 (see FIG. 31) for detecting that the effect lever 701 is in the initial tilt position, which is the position tilted most forward (on the game machine side), and the effect lever 701. Is provided with a maximum tilt position sensor 793 (see FIG. 31) that detects that the lever is in the maximum tilt position, which is the position tilted to the rearmost position (player side). Each position sensor 792,793 includes a light projecting unit that emits light and a light receiving unit that receives light from the light emitting unit, and has a space into which the lever detection piece 721 of the effect lever 701 can be inserted. It is a photosensor arranged in a substantially U-shape. Each position sensor 792,793 is said to be when the lever detection piece 721 provided on the effect lever 701 is inserted between the light emitting section and the light receiving section in response to the tilt of the effect lever 701 to block the light. It is detected that the effect lever 701 is in each position (initial tilt position or maximum tilt position). The detection signals of the position sensors 792 and 793 are input to the effect control board 920.

In the effect operating device 700 having such a configuration, the player grips the effect lever 701 and applies an operating force against the urging force of the return spring 756 to tilt the effect lever 701 from the initial tilt position (game machine side) to the maximum. It can be tilted to the position (player side). When the player releases the effect lever 701, the effect lever 701 returns to the original initial tilt position (game machine side) by the restoring force of the return spring 756. Further, the effect lever 701 receives the driving force of the motor 761 and is capable of effectively tilting operation (swinging operation) between the initial tilting position and the maximum tilting position. Further, the lever accessory 710 of the effect lever 701 is capable of rotating and reciprocating (vibrating) around a predetermined central axis X by receiving the driving force of the motor 731.

Next, a procedure for attaching the effect operation unit 700 to the glass frame 5 will be described. First, the effect operation unit 700 is placed on the pedestal portion 580 of the lower frame 560 while being fitted between the right wall portion of the ball plate unit 14 and the left wall portion of the operation switch unit 15. When the effect operation unit 700 is placed on the upper surface of the pedestal portion 580 in this way, the bottom surface insertion hole 753a formed in the bottom plate 751 of the unit base 740 and the bottom surface fixing tool 590B of the pedestal portion 580 are vertically aligned and aligned with each other. The back insertion hole 754a formed in the standing plate 752 of the unit base 740 and the back fixing tool 590A of the frame main body 570 are aligned in the front-rear direction.

Subsequently, the glass frame 5 is opened with respect to the front frame 2, and the slide operation portion 588 is pushed backward by the urging force of the coil spring 589, whereby the movable plate 585 is slid backward and held in the unlocked position. (See FIG. 34 (B)).

Next, by grasping the operation knob 592 of the bottom surface fixing tool 590B from the lower surface side of the pedestal portion 580 and pushing the bottom surface fixing tool 590B upward against the urging force of the coil spring 599b, the tip of the bottom surface fixing tool 590B is used. The shaft tip portion 591 formed in the above is inserted into the bottom surface insertion hole 753a of the unit base 740 and is projected upward. Then, after rotating the bottom surface fixative 590B 90 degrees in one direction around the axis (after rotating it from the reference rotation position to the maximum rotation position), the upward pressing force on the bottom surface fixative 590B is released. Then, the bottom surface fixing tool 590B receives the urging force of the coil spring 599b and is returned downward, so that the shaft tip portion 591 of the bottom surface fixing tool 590B is locked to the upper surface of the bottom surface locking receiving portion 753. As a result, the unit base 740 of the effect operation unit 700 and the pedestal portion 580 of the glass frame 5 are connected and fixed via the bottom surface fixture 590B.

Subsequently, the operation grip portion 592 of the back fixture 590A is grasped from the rear surface side of the glass frame 5, and the back fixture 590A is pushed forward against the urging force of the coil spring 599a to push the back fixture 590A forward. The shaft tip portion 591 formed at the tip is inserted into the rear insertion hole 754a of the unit base 740 and is projected forward. Then, after rotating the back fixture 590A 90 degrees in one direction around the axis (after rotating it from the reference rotation position to the maximum rotation position), the forward pressing force on the back fixture 590A is relaxed. Then, the back fixture 590A receives the urging force of the coil spring 599a and is returned to the rear, so that the shaft tip portion 591 of the back fixture 590A is locked to the front surface of the back locking receiving portion 754. As a result, the unit base 740 of the effect operation unit 700 and the frame body 570 of the glass frame 5 are connected and fixed via the back fixture 590A. In this way, the effect operation unit is assembled to the lower frame 560 of the glass frame 5 via the four fixtures 590 (590A, 590B).

Next, by attaching the frame relay board unit 980 to the board mounting portion 519 of the glass frame 5, the rear fixture 590A on the right side is concealed by the frame relay board unit 980. After that, when the glass frame 5 is closed with respect to the front frame 2, the slide operation portion 588 is pressed forward by the front portion of the front frame 2, and the movable plate 585 is slidably displaced to the front lock position, whereby the movable plate is displaced. The lock groove 586 of the 585 and the locked shaft portion 593 of the bottom surface fixative 590B are unevenly fitted (engaged), so that the bottom surface fixative 590B cannot rotate around the axis (see FIG. 34 (A)). That is, by restricting the rotation return of the bottom surface fixative 590B from the maximum rotation position to the reference rotation position by the engagement between the two, the shaft tip portion 591 cannot be removed from the bottom surface insertion hole 753a (that is,). , The engagement between the shaft tip portion 591 and the bottom surface locking receiving portion 753 cannot be released). Therefore, unless the glass frame 5 is opened and the movable plate 585 is retracted to the rear non-locked position, the locked state of the back fixture 590B by the movable plate 585 cannot be released, and the effect operation unit 700 is removed from the glass frame 5. Therefore, it is possible to effectively prevent mischief and cheating by an outsider such as a player who intentionally tries to remove the effect operation unit 700.

Next, a procedure for removing the effect operation unit 700 from the glass frame 5 will be described. First, the glass frame 5 is opened with respect to the front frame 2, and the slide operation portion 588 is pushed backward by the urging force of the coil spring 589, whereby the movable plate 585 is slid backward and held in the unlocked position ( See FIG. 34 (B)). As a result, the uneven fitting (engagement) between the lock groove 586 of the movable plate 585 and the bottom surface fixing tool 590B is released, and the bottom surface fixing tool 590B can be rotated around the axis. Along with this, the bottom surface fixative 590B is rotated 90 degrees from the lower surface side of the pedestal portion 580 to the other direction side around the axis (by rotating from the maximum rotation position to the reference rotation position). The locking of the shaft tip portion 591 and the upper surface of the bottom surface locking receiving portion 753 is released, and the bottom surface fixture 590B slides downward due to the urging force of the coil spring 599b. As a result, the shaft tip portion 591 of the bottom surface fixative 590B is pulled downward from the bottom surface insertion hole 753a of the unit base 740, so that the connection between the pedestal portion 580 and the unit base 740 by the bottom surface fixative 590B is released.

Subsequently, the frame relay board unit 980 is removed from the rear surface side of the glass frame 5 to expose the rear fixture 590A on the right side so that the two rear fixtures 590A on the left and right can be accessed. Along with this, the back fixture 590A is rotated 90 degrees from the rear surface side of the glass frame 5 to the other direction side around the axis (by rotating from the maximum rotation position to the reference rotation position), so that the back fixture 590A The locking of the shaft tip portion 591 and the front surface of the rear locking receiving portion 754 is released, and the rear fixture 590A slides rearward due to the urging force of the coil spring 599a. As a result, the shaft tip portion 591 of the rear fixture 590A is pulled out rearward from the rear insertion hole 754a of the unit base 740, so that the connection between the frame body 570 and the unit base 740 by the rear fixture 590A is released.

In this way, the connection state between the effect operation unit 700 by the four fixtures 590 (590A, 590B) and the lower frame 560 of the glass frame 5 is released, and the effect operation unit 700 is lifted upward from the lower frame 560. , The effect operation unit 700 can be removed from the glass frame 5.

As described above, according to the present embodiment, by making the effect operation unit 700 removable by the one-touch type fixing tool 590, the work of replacement and maintenance of the effect operation unit 700 becomes easy, and the glass frame 5 is opened. By setting the effect operation unit 700 to be in a state in which the attachment / detachment operation cannot be performed (a state in which all the fixtures 590 cannot be operated), it is possible to prevent a failure or malfunction due to a mischievous act of the player.

<Main functional configuration of pachinko gaming machines>
Next, with reference to the addition of FIG. 38, various functions of the pachinko gaming machine PM (mainly the main control board 910 / effect control board 920) according to the present embodiment will be described. FIG. 38 shows the main gaming machine PM (mainly the main). It is a functional block diagram of the control board 910 / effect control board 920).

As shown in FIG. 38, the main control board 910 has a ball entry determination means 9110, a game lottery random number generation means 9120, a hold control means 9130, a preliminary determination means 9135, a special symbol lottery processing means 9140, and a normal symbol lottery processing means 9145. The special game control means 9150, the symbol display control means 9155, the electric accessory control means 9160, the game state control means 9165, the error monitoring control means 9170, the main information storage means 9180, and the command transmission / reception means 9190 are included. Each of the above-mentioned means on the main control board 910 is composed of hardware such as a main CPU 911, ROM 912, RAM 913, and an electronic circuit provided on the main control board 910, and software such as a control program stored in the ROM 912 and the like. It is a functional expression of something.

The ball entry determination means 9110 enters each winning opening based on detection signals from the first starting opening switch 51a, the second starting opening switch 52a, the operating gate switch 53a, the large winning opening switch 54a, the general winning opening switch 55a, and the like. Judge the entry of the game ball. When the ball entry determination means 9110 detects the entry of a game ball by the first start opening switch 51a, the ball entry determination means 9110 generates an effect control command (referred to as a "first start opening winning command") to that effect, and the first 2 When the entry of the game ball is detected by the start opening switch 52a, an effect control command (referred to as “the second start opening winning command”) indicating that effect is generated, and the operation gate switch 53a is used to generate the game ball. When the passage is detected, an effect control command (referred to as "operation gate winning command") is generated to indicate that fact, and when the large winning opening switch 54a detects the entry of a game ball, it indicates that fact. When a production control command (referred to as a "large winning opening winning command") is generated and a game ball entry is detected by the general winning opening switch 55a, an effect control command indicating that fact ("general winning opening winning command") is generated. ”) Is generated and temporarily stored in the command storage area of the main information storage means 9180.

The game lottery random number generation means 9120 is used for a winning / failing lottery of a special symbol by taking in a built-in random number generated by the random number generation circuit of the main control microcomputer 915 by software and adding a soft random number per special symbol described later to the built-in random number. Generate a random number per special symbol. Further, the game lottery random number generation means 9120 is provided with a random number counter for generating various software random numbers by the program processing of the main CPU 911. These random number counters play a role as a random number generation means for generating random numbers by software. As this software random number, the initial value for performing a new update after the update of one cycle of the special symbol per soft random number added to the above-mentioned built-in random number for the hit random number generation and the special symbol per soft random number is completed. Soft initial value random number per special symbol for determining, special symbol stop symbol random number used for determining the hit symbol (combination of symbols that activates the condition device) as the stop symbol of the special symbol, special symbol stop symbol random number Special symbol stop symbol initial value random number for determining the initial value for new update after one cycle of update is completed, special symbol fluctuation pattern random number for selection of special symbol variation pattern, Random number per normal symbol to be used for winning / failing lottery of normal symbol, initial value random number per normal symbol to determine the initial value for new update after one cycle update of random number per normal symbol is completed, Ordinary symbol variation pattern Random numbers for use in selecting the variation pattern of the ordinary symbol are included. These software random numbers are updated once each time a timer interrupt process occurs (increment, decrement, addition of prime numbers, etc.), and the initial value random number is not executed while the timer interrupt process is not executed (increment, decrement, addition of prime numbers, etc.). (During loop processing) is also updated using the remaining time of the interrupt cycle.

The hold control means 9130 includes a special symbol hold control means 9131 and a normal symbol hold control means 9132.

The special symbol hold control means 9131 is a lottery random number value related to the special symbol game, which is a random number value per special symbol, per special symbol, triggered by the entry of the game ball into the first start port 51 or the second start port 52. The symbol random value and the special symbol fluctuation pattern random value are acquired, and the random value is managed as the operation pending ball information of the first special symbol or the second special symbol. The special symbol holding control means 9131 is a main information storage means in which the operation holding ball information of the first special symbol or the second special symbol is combined with the entry order of the holding balls up to a predetermined upper limit number (4 pieces). Temporarily stored in the first special symbol holding storage area or the second special symbol holding storage area of 9180.

In the first special symbol hold storage area and the second special symbol hold storage area, the hold 1 storage area (first hold storage area) and the hold 2 storage area (2) are in the order of entry into the starting ports 51 and 52. A hold storage area), a hold 3 storage area (third hold storage area), and a hold 4 storage area (fourth hold storage area) are provided. Each hold storage area can store a random number per special symbol, a random number per special symbol, and a random number of special symbol variation patterns as a set of operation hold ball information. The operation hold ball information is stored in the order of hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 storage area, while hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 storage. It is digested in the order of areas (principle of first-in first-out). Further, when the reserved ball information in the reserved 1 storage area is digested, the reserved ball information stored in the reserved 2 storage area, the reserved 3 storage area, and the reserved 4 storage area is shifted to the lower numbered storage area, respectively. Hold 4 Clears the contents of the storage area to zero.

Further, the special symbol holding control means 9131 has a first special symbol holding ball number counter for counting the number of operating holding balls of the first special symbol, and a second special symbol holding ball number counter for counting the number of operating holding balls of the second special symbol. It has a special symbol reserved ball count counter. The special symbol hold control means 9131 adds 1 to the corresponding counter every time one special symbol operation hold ball is acquired as an update process of the number of operation hold balls of the special symbol, and one operation hold ball is digested. The corresponding counter is subtracted by 1 for each.

Further, when the special symbol hold control means 9131 updates (adds or subtracts) the number of operation hold balls of the first special symbol or the second special symbol, the effect control command including the update information of the hold ball number (“symbol memory”). A number command) is generated and temporarily stored in the command storage area of the main information storage means 9180. This one command includes information on both the number of reserved balls for the first special symbol and the number of reserved balls for the second special symbol. As a general rule, the operation-holding balls of each special symbol are digested in the order in which they are entered, but in the present embodiment, the variation display of the second special symbol is preferentially executed over the first special symbol. In order to adopt the so-called priority digestion, while the operation hold ball related to the second special symbol game exists, the operation hold related to the second special symbol game is held regardless of the existence of the operation hold ball related to the first special symbol game. It is configured to preferentially digest the sphere. Under this priority digestion, when the operation holding ball of the second special symbol is present, even if the operation holding ball of the first special symbol is present, the operation holding ball of the first special symbol is digested. It will be put on hold.

The normal symbol hold control means 9132 is a lottery random value related to the normal symbol game, triggered by the entry of the game ball into the operating gate 53, which is a random value per normal symbol, a symbol random value per normal symbol, and a normal symbol variation pattern. A random number value is acquired, and the random number value is managed as operation holding ball information of a normal symbol. The normal symbol hold control means 9132 stores the operation hold ball information of the normal symbol up to a predetermined upper limit number (4 pieces) in the normal symbol hold storage area of the main information storage means 9180 in the form of being combined with the entry order of the hold balls. Temporarily memorize. Further, the normal symbol holding control means 9132 has a normal symbol holding ball number counter for counting the number of operating holding balls of the normal symbol. The normal symbol hold control means 9132 adds 1 to the corresponding counter for each acquisition of one normal symbol hold ball as an update process of the number of hold balls of the normal symbol, and one action hold ball is consumed. The corresponding counter is subtracted by 1 for each.

When the pre-determination means 9135 acquires an operation-holding ball with a special symbol at a predetermined pre-determination timing, the pre-determination means 9135 executes a pre-determination for pre-reading notice for the operation-holding ball. As an example of the above-mentioned pre-judgment timing, when (1) waiting for a hit and when the operation holding ball of the first special symbol is acquired while the electric chew support function is not operating, (2) waiting for a hit and Either when the operation hold ball of the second special symbol is acquired while the electric chew support function is operating, or when the operation hold ball of the second special symbol is acquired during the big hit or the small hit. It is time to meet the conditions. The above-mentioned pre-judgment timing is an example, and the pre-judgment timing is changed according to the specifications of the gaming machine (for example, it has a start port related to the second special symbol having no ordinary electric accessory, and eight pieces are reserved at normal times. For models that can store pachinko machines, the above (1) can be applied not only to the first special symbol but also to the second special symbol, etc.), or even if a specification that makes a pre-judgment at any time without setting a pre-judgment timing is adopted. good. Further, in each game state, only the operation-holding ball of the special symbol that is the subject of the game may be the target of the preliminary determination. For example, in the normal game state, only the operation-holding ball of the first special symbol is the target of the preliminary determination. Therefore, in the time-saving game state, the latent probability change game state, and the probability change game state, it is preferable that only the operation holding ball of the second special symbol is the target of the preliminary determination. Specifically, the pre-determination means 9135 reads the random number value corresponding to the operation hold ball acquired this time from the first special symbol hold storage area or the second special symbol hold storage area of the main information storage means 9180, and determines whether or not the result is correct. Pre-judgment (pre-judgment of hit / fail), pre-judgment of symbol (pre-judgment of symbol), and pre-judgment of fluctuation pattern (pre-judgment of fluctuation pattern) are sequentially executed. Although the pre-judgment table used in each pre-judgment is not shown, the area corresponding to the total number of random numbers in each of the pass / fail pre-judgment table, the symbol pre-judgment table, and the variation pattern pre-judgment table is divided into a plurality of areas. A lottery ID (a number indicating the result of the pre-judgment (also referred to as a "pre-judgment number")) is assigned to each of these areas (determination number). Therefore, the result of this preliminary determination is based on the result of the main lottery by the special symbol lottery processing means 9140 described later (result of winning / failing determination, result of symbol determination, result of variation pattern determination). The winning / failing pre-determination table, the symbol pre-determining table, and the like may be the same as the winning / failing lottery table and the symbol lottery table used for the lottery when the fluctuation is actually started. Here, the fluctuation pattern pre-determination table may change the game status at the start of fluctuation (whether or not there is a probability change, whether or not there is a time reduction, whether or not it is during a limited frequency period that refers to a special table, the number of reserved balls, etc.). Therefore, as described above, it is desirable to determine which of the plurality of regions is included. Further, as a modification, it is configured to predetermine a random value such as a register on the main CPU 911 that is temporarily stored before being stored in the first special symbol hold storage area or the second special symbol hold storage area. You may. Then, the pre-determination means 9135 sequentially generates an effect control command (referred to as a "pre-determination command") including information on the result of the pre-determination (pre-determination number), and uses this as a command storage area of the main information storage means 9180. Store in.

The special symbol lottery processing means 9140 includes a special symbol winning / failing determination means 9141, a special symbol stop symbol determining means 9142, and a special symbol variation pattern determining means 9143. When the change start condition of the first special symbol or the second special symbol is satisfied, the special symbol lottery processing means 9140 is stored in the earliest storage area (reserved 1 storage area) of the special symbol reservation storage area in the main information storage means 9180. The stored special symbol per random value, special symbol per symbol random value, and special symbol variation pattern random value are read out and used as the special symbol hit / fail determination area, special symbol symbol determination area, and special symbol variation pattern of the main information storage means 9180. Store each in the judgment area. Here, "the condition for starting the fluctuation of the first special symbol is satisfied" means that (A1) the jackpot is not in progress, (A2) the first special symbol and the second special symbol are waiting for fluctuation, and (A3). ) When all the conditions that the operation holding ball of the first special symbol exists is satisfied. In addition, "the condition for starting the change of the second special symbol is satisfied" means that (B1) the jackpot is not in progress, (B2) the first special symbol and the second special symbol are waiting for change, and (B3). It is when all the conditions that the operation holding ball of the second special symbol exists is satisfied. When the fluctuation start condition of the first special symbol and the fluctuation start condition of the second special symbol are satisfied at the same time, the fluctuation start condition of the second special symbol is preferentially processed under the above-mentioned priority digestion. do.

The special symbol winning / failing determination means 9141 reads a random value per special symbol from the special symbol winning / failing determination area of the main information storage means 9180, executes a winning / failing determination, and the determination result corresponds to any of big hit, small hit, and miss. Decide if you want to. The result of this hit / fail judgment is temporarily stored in the special symbol judgment flag of the main information storage means 9180 (for example, big hit data "55H", small hit data "33H", miss data "00H"), and is used in the subsequent processing. After that, it is cleared when the fluctuation of the special symbol stops. The special symbol winning / failing determination means 9141 holds a special symbol winning / failing lottery table referred to at the time of this winning / failing determination. In the special symbol winning / failing lottery table, the random number range of the random number value per special symbol and the result of the winning / failing determination of the special symbol (big hit, miss) are associated with each other. In the game state (low probability state) in which the probability fluctuation function of the special symbol is not activated in the hit / fail judgment of the special symbol, for example, when the random number value per special symbol falls in the range of "0 to 204", it becomes a big hit. In the gaming state (high probability state) in which the probability fluctuation function of the special symbol is activated, a big hit is obtained when the random number value per special symbol falls in the range of "0 to 1506". That is, when the probability fluctuation function of the special symbol is activated, the winning probability of the big hit changes from the low probability "1 / 319.69" to the high probability "1 / 43.49". In this way, the jackpot winning probability changes according to the gaming state, but the jackpot winning probability is set equally between the winning / failing determination of the first special symbol and the winning / failing determination of the second special symbol. In this embodiment, "small hit" is not set as the result of the hit / fail determination of the special symbol, but "small hit" may be set as the result of the hit / miss determination of the special symbol. The winning probability of a small hit is set to the same winning probability regardless of the gaming state (low probability state, high probability state).

The special symbol stop symbol determining means 9142 determines the stop symbol of the first special symbol or the second special symbol based on the result of the winning / failing lottery of the first special symbol or the second special symbol. The special symbol stop symbol determining means 9142 has a first special symbol stop symbol table and a second special symbol stop symbol table that are referred to when determining a jackpot symbol (big hit type) of the first special symbol and the second special symbol. is doing. In each special symbol stop symbol table, a plurality of types of jackpot symbols (big hit types) are assigned to the special symbol stop symbol random value. Then, the contents of the jackpot (the number of operations of the probability fluctuation function and the fluctuation time shortening function of the special symbol, the operation pattern of the big winning opening, etc.) are associated with each jackpot symbol (big hit type). In the present embodiment, the "specific jackpot" means a jackpot (probability variable jackpot) that triggers the activation of the probability fluctuation function of the special symbol after the jackpot game ends, and the "normal jackpot" means the special symbol after the jackpot game ends. It means a big hit (non-probable variable big hit) that does not trigger the activation of the probability fluctuation function of. In this embodiment, three types of jackpots are provided: 16R specific jackpot, 8R specific jackpot, and 4R normal jackpot. The expected value of winning the prize ball (expected value of winning the prize ball) in the special game is 16R specific jackpot> 8R specific jackpot> 4R specific jackpot. Then, when a big hit is made in the winning / failing lottery of the first special symbol, a 16R specific big hit is selected with a predetermined probability, whereas when a big hit is made in the winning / failing lottery of the second special symbol, it is predetermined. By selecting the 16R specific jackpot with a higher probability than the probability, it is advantageous for the player to win a prize at the second starting opening rather than winning at the first starting opening in that a large number of balls can be obtained. ..

The special symbol variation pattern determining means 9143 determines the variation pattern of the special symbol based on the special symbol variation pattern random value. Here, the special symbol variation pattern determining means 9143 holds a plurality of types of variation pattern tables that are referred to when selecting a variation pattern of the special symbol. The special symbol variation pattern determining means 9143 selects any variation pattern table from a plurality of types of variation pattern tables based on the current variation pattern selection state and the result of the winning / failing lottery. Each variation pattern table defines a plurality of variation patterns. For each variation pattern, the variation time is set for each variation pattern as the end condition of the symbol variation, and it is premised that the symbol variation by the decorative symbol composed of a plurality of symbols is also executed at the variation time. Is defined as.

The variation effect of the decorative symbol performed in conjunction with the variation display of the special symbol is determined based on the type (variation time) of the variation pattern of the special symbol. For example, "ultra-shortening fluctuation", "shortening fluctuation", and "normal fluctuation" are effects in which the three rows of decorative symbols fluctuate, and the so-called "out of place" is achieved without going through the reach state even once. be. These non-reach deviations (ultra-shortened fluctuation, shortened fluctuation, and normal fluctuation) are mutually variable in that the fluctuation display stops in a shorter time in the shortened fluctuation than in the normal fluctuation and in the ultra-shortened fluctuation than in the shortened fluctuation. different.

"N reach (normal reach)" is a state in which the same decorative symbol is stopped in two rows (generally the left column and the right column) of the three rows of decorative symbols (reach state), and the remaining one row (general). If a different decorative symbol stops in the middle row), it will be "missing", and if the same decorative symbol stops in the remaining one row (generally, the middle row), it will be a "big hit".

"SP reach (super reach)" is a reach production with a relatively higher expectation of big hits than the above N reach, and after the reach is established, it develops from the N reach, for example, still images and live-action images such as animation and live-action. Etc. are displayed. In the variation pattern type of this embodiment, the jackpot expectation is set to be higher in the order of "non-reach" <"N reach" <"SP reach". "Pseudo-ream" means that the decorative symbol is temporarily stopped (pseudo-stop, temporarily stopped) and re-variablely displayed during one variable display of the decorative symbol, so that the variable display is performed multiple times in a pseudo manner. It is an effect that makes it look like (pseudo continuous effect, pseudo variable effect, pseudo continuous variable effect, re-variable effect). That is, the pseudo-ream is an effect of executing the pseudo-variation in which the temporary stop or the fixed stop is executed a plurality of times after all the decorative symbols in the three rows start to change or re-change. It is shown that the larger the number of pseudo-reams (the number of pseudo-variations), the higher the possibility of developing SP reach with high expectation of big hits.

After selecting the variation pattern of the special symbol, the special symbol variation pattern determining means 9143 instructs the effect control board 920 to start the variation of the decorative symbol, so that the communication with the effect control board 920 is normally performed. An effect control command (communication inspection command) for confirming whether or not it is present, an effect control command (variation addition information specification command) including a variation addition pattern of a special symbol (information for adding or subtracting a variation time), and a variation pattern of a special symbol. Generate production control commands (variable pattern specification commands) that include information, effect control commands (symbol specification commands) that include information on character production numbers (symbols and game states), etc. (hereinafter, these commands are collectively referred to as ". (Referred to as "variation start command"), which is stored in the command storage area of the main information storage means 9180.

The normal symbol lottery processing means 9145 includes a normal symbol hit / miss determination means 9146, a normal symbol stop symbol determination means 9147, and a normal symbol variation pattern determination means 9148. When the normal symbol fluctuation start condition is satisfied, the normal symbol lottery processing means 9145 reads out the normal symbol per normal symbol value and the normal symbol fluctuation pattern random value stored in the earliest storage area in the normal symbol hold storage area. It is stored in the normal symbol hit / miss determination area and the normal symbol variation pattern determination area of the main information storage means 9180, respectively. Here, the "conditions for starting the fluctuation of the normal symbol" are (1) waiting for the fluctuation of the normal symbol, and (2) the existence of an operation holding ball of the normal symbol. When all of these conditions are satisfied, it is determined that the normal symbol is in a state in which fluctuation start is possible (a state in which the fluctuation start condition is satisfied).

The normal symbol hit / fail determination means 9146 reads a random value per normal symbol from the normal symbol hit / miss determination area of the main information storage means 9180, executes a hit / fail judgment of the normal symbol, and the determination result is either "hit" or "missing". Determine if it applies to. The result of the hit / fail determination of the normal symbol is temporarily stored in the normal symbol determination flag of the main information storage means 9180, used in the subsequent processing, and then cleared when the fluctuation of the normal symbol is stopped. The ordinary symbol winning / failing determination means 9146 holds a normal symbol winning / failing lottery table (not shown) that is referred to when determining whether or not the ordinary symbol is correct. The hit probability of the normal symbol is set to "1/3001" when the electric chew support function (probability fluctuation function of the normal symbol) is not activated, and the electric chew support function (probability fluctuation function of the normal symbol) is activated. If so, it is set to "2999/3001".

The normal symbol stop symbol determination means 9147 refers to a normal symbol stop symbol table (not shown), and if the result of the hit / fail determination of the normal symbol is a hit, the predetermined hit symbol (the trigger for the operation of the normal electric accessory 52b). On the other hand, if the result of the hit / fail determination of the normal symbol is out of order, a predetermined out-of-order symbol (a stop symbol that does not trigger the operation of the ordinary electric accessory 52b) is selected. In the present embodiment, the symbol A and the symbol B are assigned as the winning symbols of the ordinary symbol, while the symbol C is assigned as the outlier symbol of the ordinary symbol.

The ordinary symbol variation pattern determining means 9148 reads the ordinary symbol variation pattern random value from the ordinary symbol variation pattern determination area of the main information storage means 9180, and also refers to the ordinary symbol variation pattern table (not shown) to refer to the ordinary symbol variation pattern table. Determine (variation time). The fluctuation time of the normal symbol is set to "0.6 seconds" when the electric chew support function (function to shorten the fluctuation time of the normal symbol) is not activated, and the electric chew support function (function to shorten the fluctuation time of the normal symbol). Is set to "0.2 seconds" when is operating. Regardless of which normal symbol variation pattern is selected, the fixed stop time (fixed display time) of the normal symbol is set to "0.1 seconds". The fixed stop time (fixed display time) of the normal symbol is the time when the normal symbol is definitively stopped and displayed (the time when the completely stopped state is maintained). In the control of the normal symbol, in order to reduce the processing load of the main control board 910, when the electric chew support function is not operating, the hit probability of the hit / fail judgment of the normal symbol is set to "0", and the normal symbol is controlled. It is also conceivable to adopt a specification in which the fluctuation time is a single one.

Further, the ordinary symbol lottery processing means 9145 determines the opening pattern (opening time) of the ordinary electric accessory 52c according to the result of the hit / fail determination of the ordinary symbol. The ordinary symbol lottery processing means 9145 holds an ordinary electric accessory opening pattern table that is referred to when determining an opening pattern (opening time) of the ordinary electric accessory 52b. The opening pattern (opening time) of the normal electric accessory 52c is set to "0.2 seconds" when the electric chew support function (opening extension function) is not operating, and the electric chew support function (opening extension function) is set. If it is operating, "5.8 seconds" is set. The opening pattern of the ordinary electric accessory 52b may be different depending on the type of the hit symbol of the ordinary symbol. For example, when the electric chew support function (opening extension function) is activated as the opening pattern of the ordinary electric accessory 52b, if the hit symbol of the ordinary symbol is symbol A, "3 seconds opening x 1 time → 2. 8 seconds open x 1 time (total open time 5.8 seconds) ", and if the hit symbol of the normal symbol is symbol B," 2.8 seconds open x 1 time → 3 seconds open x 1 time (total open time 5) .8 seconds) ".

When the result of the hit / fail determination of the special symbol is a big hit, the special game control means 9150 determines the execution time (demo time) of the big hit start demo and the big hit end demo according to the determined big hit type (symbol group). Determine the execution time (round time) of the round game. Then, the special game control means 9150 instructs the effect control board 920 side to execute the effect control command (referred to as "big hit start demo command") and the effect end demo effect. An effect control command (referred to as a “big hit end demo command”) is generated and stored in the command storage area of the main information storage means 9180. The jackpot start demo command also serves as an opportunity to determine the content of a series of jackpot middle effects (big hit start demo effect, round effect, jackpot end demo effect) developed during the jackpot game on the effect control board 920 side. Become. Further, the special game control means 9150 generates an effect control command (referred to as a “round effect designation command”) for instructing the start of the round effect corresponding to each round game in each round game during the big hit game. , This is stored in the command storage area of the main information storage means 9180. This round effect designation command includes information on the current number of rounds and information on opening and closing of the grand prize opening 54.

The symbol display control means 9155 includes a special symbol display control means 9156 and a normal symbol display control means 9157. The special symbol display control means 9156 causes the first special symbol display device 61 to variably display the first special symbol according to the fluctuation pattern (variation time) of the first special symbol, and confirms and displays the first special symbol after the fluctuation display. Let me. Further, the special symbol display control means 9156 causes the second special symbol display device 62 to variably display the second special symbol according to the fluctuation pattern (variation time) of the second special symbol, and displays the second special symbol after the variation display. Confirm display. The special symbol display control means 9156 has a special symbol game timer for managing the time (variable time, fixed display time) related to the display of the first special symbol and the second special symbol. The operating states of the first special symbol display device 61 and the second special symbol display device 62 are monitored based on the special symbol game status of the main information storage means 9180. The special symbol display control means 9156 requests the effect control board 920 to confirm the decorative symbol when the fluctuation of the special symbol is stopped (that is, at the timing when the value of the special symbol game timer becomes "0"). Generates an effect control command (referred to as "fluctuation stop command"). The normal symbol display control means 9157 causes the normal symbol display device 65 to variablely display the normal symbol according to the fluctuation pattern (variation time) of the normal symbol, and confirms and displays the normal symbol after the fluctuation display. The normal symbol display control means 9157 has a normal symbol game timer for managing the time (variable time, fixed display time) related to the display of the normal symbol. The operating state of the normal symbol display device 65 is monitored based on the normal symbol game status of the main information storage means 9180.

Further, the special symbol display control means 9156 issues an effect control command (referred to as "standby demo command") that triggers the execution of the standby demo effect (customer waiting demo effect) when the interrupted state of the game continues for a predetermined time or longer. It is generated and stored in the command storage area of the main information storage means 9180. "The suspended state of the game continues for a predetermined time or longer" means that the period in which the operation holding ball of the special symbol does not exist and the change display of the special symbol is not performed continues for a predetermined time or longer. If the period in which the game ball is not fired continues for a predetermined time or longer, or if the period in which the game ball has not entered all the winning openings continues for a predetermined time or longer, the game is interrupted for a predetermined time or longer. It may be a continuous specification.

When the result of the hit / fail determination of the special symbol is a big hit, the electric accessory control means 9160 outputs a control signal to the special electric accessory solenoid 54c as a big hit game process after the confirmation display of the special symbol, and the special electric accessory control means 9160. The object 54b is controlled to open and close according to a predetermined operation pattern. In the jackpot game, one opening / closing operation of the special electric accessory 54b is regarded as one round game (unit game), and the round game is continuously executed for a predetermined number of rounds. The electric accessory control means 9160 holds a large winning opening opening counter for storing the number of operations of the special electric accessory 54b (that is, the number of running rounds). Here, the special electric accessory 54b in the big hit game
The operation end condition (end condition of the unit game) is that a specified count number (“10” in this embodiment) of game balls has entered the large winning opening 54, or the opening time of the large winning opening 54. Has reached the maximum opening time (“29 seconds” in this embodiment).

Further, the electric accessory control means 9160 outputs a control signal to the ordinary electric accessory solenoid 52c when the result of the hit / fail determination of the ordinary symbol corresponds to the hit, and the ordinary electric accessory 52b (the first) for a predetermined opening time. 2 The opening / closing control of the starting port 52) is performed. Here, as described above, the electric accessory control means 9160 opens the normal electric accessory 52b for 0.2 seconds in the low base state in which the electric chew support function (opening extension function) is not operating. Then, in the high base state in which the electric chew support function (opening extension function) is operating, the normal electric accessory 52b is opened for 5.8 seconds. Here, the operation end condition of the ordinary electric accessory 52b is that a predetermined number of game balls (“10” in this embodiment) have entered the second starting port 52, or that the second starting port 52 has a predetermined number of game balls. The opening time has reached the maximum opening time (“0.2 seconds” or “5.8 seconds” in this embodiment).

When the result of the hit / fail determination of the first special symbol or the second special symbol is a big hit, the game state control means 9165 is based on the big hit type (type of symbol group) and the game state at the time of winning the big hit. The game state after the end of the jackpot game is determined, and the game state after the end of the big hit game is switched. In the present embodiment, a normal game state, a time-saving game state, and a probabilistic game state are set as a plurality of types of game states. As the types of the game state, (1) the game state in which the probability fluctuation function of the special symbol, the fluctuation time shortening function of the special symbol, and the electric chew support function are activated is called "probability change state" or "probability change game state", and ( 2) The gaming state in which the special symbol's fluctuation time shortening function and the electric chew support function are activated without the special symbol's probability fluctuation function operating is called the "time saving state" or "time saving gaming state", and (3) all The state in which the function is not operating is referred to as a "normal state" or a "normal gaming state". Here, it can be said that the "probability variation game state" and the "time saving game state" are more advantageous game states for the player than the "normal game state". Therefore, as a gaming state that is more advantageous to the player than the normal gaming state, the probabilistic gaming state and the time-saving gaming state are also referred to as "advantageous gaming state".

In addition, each gaming state is determined by the combination of the operating state of the probability fluctuation function of the special symbol (high probability state / low probability state) and the operating state of the electric chew support function (high base state / low base state) (1). ) Probability variable gaming state can be expressed as "high probability high base state", (2) time-saving gaming state can be expressed as "low probability high base state", and (3) normal gaming state can be expressed as "low probability low base state". In addition, the function for shortening the fluctuation time of the special symbol is such that the fluctuation time of the special symbol of the first special symbol and the second special symbol, which is at least the main player of the game in the game state, is shortened. Means. That is, in the present embodiment, when the function for shortening the variation time of the special symbol is activated, at least the variation time of the first special symbol (normal game state) in the gaming state (normal gaming state) in which the variation display of the first special symbol is the main game. In the game state (probability variation game state, latent probability game state, time-saving game state) in which the variation display of the second special symbol is the main game, the variation time of at least the second special symbol (average variation time) is shortened. Time) is shortened.

Further, the game state control means 9165 determines the variation pattern selection state after the end of the jackpot game based on the jackpot type (type of symbol group) when the jackpot game is executed, and after the end of the jackpot game. The fluctuation pattern selection state of is switched. The variation pattern selection state is one of the conditions referred to when selecting the variation pattern table of the above-mentioned special symbol. In the present embodiment, a normal selection state, a time saving selection state, and a probability variation selection state are set as a plurality of types of variation pattern selection states, depending on the determined game state, jackpot type, number of variation display times of special symbols, and the like. Therefore, one of a plurality of types of variation pattern selection states is selectively set. The switching time of the variable pattern selection state is the end of the special game or the end of the variable pattern selection state.

Further, the game state control means 9165 generates an effect control command (referred to as a “game state designation command”) including the current game state information and the variation pattern selection state information, and stores the command of the main information storage means 9180.

As the update time of these random numbers, the remaining time when the command analysis is not performed in the main process on the effect control side described later (when the effect control command is not received from the main control board 910) is used for the update. do.

The effect control means 9220 includes the effect mode control means 9221, the hold information display control means 9222, the look-ahead notice control means 9223, the variable effect control means 9224, the decorative symbol control means 9225, the notice effect control means 9226, and the special game effect control means 9227. include.

The effect mode control means 9221 is based on a game state designation command from the main control board 910, and is consistent with the game state and the variation pattern selection state managed on the main control board 910 side. Also called "game production mode"). In the present embodiment, "normal effect mode", "time saving effect mode", and "probability variation effect mode" are set as a plurality of types of effect modes, and the gaming state (or variation pattern) managed on the main control board 910 side is set. One of a plurality of types of effect modes is selectively set according to the selected state), the number of times of variation display of the special symbol, and the like, and the variation effect according to the set effect mode is executed. In the present embodiment, when the gaming state is the normal gaming state, the "normal effect mode" is set, and when the gaming state is the time-saving gaming state, the "time-saving effect mode" is set, and the gaming state is the probabilistic gaming state. At some point, the "probability change effect mode" is set. When any of the effect modes is set, as an effect (variable effect) suggesting that the user is staying in the effect mode, a background image dedicated to the effect mode (background image that is displayed on the back of the decorative pattern) is displayed on the screen. ) Is displayed, and the BGM dedicated to the effect mode is output from the speakers 8, 170, and 251. Since the background image and the BGM are set to be different from each other for each effect mode in this way, the player can recognize which effect mode is currently staying from the type of the background image or the BGM. ing.

The hold information display control means 9222 has a first hold ball number counter for counting the number of operation hold balls of the first special symbol, and a second hold ball number counter for counting the number of operation hold balls of the second special symbol. Have. When the hold information display control means 9222 receives the symbol storage number command from the main control board 910, the hold information display control means 9222 updates (adds) the value of the corresponding counter based on the information on the number of operation hold balls included in this command. On the other hand, the hold information display control means 9222 updates (subtracts) the value of the corresponding counter when the change start command from the main control board 910 is received, that is, when the operation hold ball is digested. Further, the hold information display control means 9222 has the number of operation hold balls of the first special symbol in the hold image display area 72 of the effect display device 70 based on the values of the first hold ball number counter and the second hold ball number counter. Control is performed to display the number of reserved images corresponding to the number of reserved images corresponding to the number of reserved images corresponding to the number of reserved balls for operation of the second special symbol. Further, in the hold information display control means 9222, the operation hold ball (the earliest operation hold ball) of the first special symbol or the second special symbol is digested in the changing image display area 73 of the effect display device 70. , Controls to display the changing image displayed by switching to the holding image corresponding to this operation holding ball. In the present embodiment, unless explicitly mentioned, the reserved image of the first special symbol and the reserved image of the second special symbol are not distinguished and are simply referred to as a "pending image", and are referred to as a changing image of the first special symbol. It may be simply referred to as a "changing image" without distinguishing it from the changing image of the second special symbol.

The look-ahead notice control means 9223 executes a look-ahead determination (referred to as "look-ahead lottery") for the operation holding ball that is the target of the look-ahead notice effect. The look-ahead notice effect is a so-called continuous advance notice effect that announces the possibility of a big hit or a high expectation effect (for example, reach effect) over one or more variable displays before the operation hold ball to be read ahead is digested. It occurs as one aspect. At this time, the pre-reading lottery is performed based on the information of the pre-determination result included in the pre-determination command from the main control board 910. Here, when the pre-reading advance notice control means 9223 receives the pre-determination command from the main control board 910, it distinguishes between the information of the pre-determination result of the first special symbol and the information of the pre-determination result of the second special symbol, respectively. Up to a predetermined upper limit number (4 pieces) is temporarily stored in the look-ahead information storage area of the sub-main information storage means 9260 in a form combined with the entry order of the operation holding balls. This look-ahead information storage area has the same configuration as the hold storage area of the main control board 910, and holds 1 storage area (first hold storage area) in the order of entry into the starting ports 51 and 52. A hold 2 storage area (second hold storage area), a hold 3 storage area (third hold storage area), and a hold 4 storage area (fourth hold storage area) are provided, respectively. Each reserved storage area can store information on the result of pre-determination of hit / fail, information on the result of pre-determination of symbols, and information on the result of pre-determination of fluctuation pattern as a set. The information of the preliminary determination result is stored in the order of hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 storage area, while hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 It is digested in the order of storage area (principle of first-in first-out). Further, when the information of the preliminary determination result of the reserved 1 storage area is digested, the information of the preliminary determination result stored in the reserved 2 storage area, the reserved 3 storage area, and the reserved 4 storage area is stored in the storage area of the lower number, respectively. At the same time as shifting, the contents of the reserved 4 storage area are cleared to zero.

The variation effect control means 9224 is based on the information (variation pattern information, variation addition information, etc.) included in the variation start command from the main control board 910, and the variation process from the variation start to the stop in the variation display of the decorative symbol (effect process). ) Is determined by lottery. The variation effect control means 9224 holds a plurality of types of variation effect pattern tables referred to when selecting the variation effect pattern of the decorative symbol, and the variation pattern of the special symbol from the plurality of types of variation effect pattern tables. A variable effect pattern table corresponding to (variable time) is selected. Here, while the main fluctuation pattern of the special symbol (for example, "SP reach A" or "SP reach B") is determined on the main control board 910 side, the effect control board 920 side is based on the main fluctuation pattern. Sub-variable patterns of decorative patterns (for example, "SP reach A1, A2 ...", "SP reach A2, A3 ...", etc.) that specify the scenario of the effect display process in detail are determined. The variation effect pattern of the decorative symbol defines a variation display mode of the decorative pattern, that is, a scenario of a series of effect display processes from the start of the variation of the decorative symbol to the end of the variation, and a notice is given at each stage in the display process. The timing to generate the production is also defined as the time schedule. In addition, regarding the variation effect pattern of this decorative symbol, even if the variation pattern of the special symbol is the same (even if the variation start command of the same information is received), if the effect modes during the stay are different, they are produced mutually. Variable production patterns with different contents can be selected. That is, the variable effect pattern table is prepared for each effect mode during the stay.

Further, the variation effect control means 9224 receives the standby demo command from the main control board 910, and receives the standby demo command until the variation display of the special symbol is started (the next variation start). During the customer waiting period (until the command is received), for example, a standby demo effect (customer waiting demo effect) for playing a moving image for demonstration is executed.

The decorative symbol control means 9225 is decorated based on the information (stop symbol information, game state information) included in the variation start command from the main control board 910 and the above variation effect pattern determined by the variation effect control means 9224. The final combination of stopped symbols (left symbol, middle symbol, right symbol) is determined by lottery. In this example, three symbol rows including a plurality of types of decorative symbols are configured, and the decorative symbols are formed by, for example, identification elements composed of numbers and the like. Further, the decorative symbol control means 9225 holds a plurality of types of stop symbol pattern tables that are referred to when a combination of stop symbols of decorative symbols (also referred to as "stop symbol pattern") is determined by lottery. Examples of the plurality of types of tables include a stop symbol pattern table for big hits, a stop symbol pattern table for loss of reach, and a stop symbol pattern table for non-reach loss. The stop symbol of the decorative symbol is formed as a combination of three symbols, and includes a "stop symbol indicating a big hit (big hit symbol)" and a "stop symbol indicating a missed symbol (missing symbol)". The jackpot symbol indicating the specific jackpot (probability variation jackpot) is a combination of stop modes (for example, "7, 7, 7") in which three symbols having the same odd number are arranged. The jackpot symbol indicating a normal jackpot (non-probability variable jackpot) is a combination of stop modes (for example, "2.2.2") in which three identical even-numbered symbols are aligned. The out-of-order symbol is a combination of stop modes (for example, "1 ・ 3 ・ 8") in which at least one of the three symbols is a symbol with a number different from the other numbers. Here, among the out-of-reach symbols, the out-of-reach symbol is a combination of stop modes (for example, "3.1.3") in which only the middle symbol is displaced back and forth by several frames while the left symbol and the right symbol match. Become. In the case of a small hit symbol or a 2R big hit symbol even if it is a big hit symbol, it may be a combination of predetermined stop modes such as "3, 5, 7". In addition, when the lottery result is out of reach, a specific result called a so-called "chance eye" (for example, "1 ・ 2 ・ 3" or "5, 6 ・ 7" as the order), etc. "2, 2, 3", "5, 5, 6", etc.) may be selected as the deviation. Furthermore, in the above-mentioned pseudo-continuous effect, when a temporary stop display and a re-variable display are performed before the final stop symbol is confirmed and displayed, a special symbol (a special stop symbol that suggests the occurrence of a pseudo-ream) is used. Pseudo-ream pattern) is selected. When displaying a temporary stop symbol that suggests the occurrence of a pseudo-ream, display a character such as "NEXT" for at least one stop symbol (typically a middle symbol) among the stop symbols of the three rows of decorative symbols. There is a case (for example, "2, NEXT, 3", etc.) in which a special symbol (pseudo-continuous symbol) is replaced and displayed. The stop order for stopping the decorative symbol is predetermined for each of the following variable effect patterns, and in principle, the left symbol → the right symbol → the middle symbol are stopped in this embodiment. However, if the fluctuation time is set to be extremely short, the left symbol, middle symbol, and right symbol are stopped almost at the same time, and if it is a special variation effect pattern, the right symbol → It is also possible to stop in the order of the middle symbol → the left symbol, and in this case, the jackpot expectation tends to be relatively high. In addition, regardless of the stop order, it is desirable that the left symbol, the right symbol, and the middle symbol start the fluctuation at the same time when the fluctuation starts. However, as a special variation effect pattern, the variation may be started in the order of the left symbol, the right symbol, and the middle symbol.

The advance notice effect control means 9226 draws a notice effect pattern that defines the content of the advance notice effect to be executed at each stage of the change process of the decorative symbol according to the scenario of the change effect pattern determined by the change effect control means 9224. decide. The notice effect pattern includes an effect pattern that temporarily or stepwise displays an image of a specific character, an animation, etc., an effect pattern that outputs a specific sound, an effect pattern that emits an effect lamp LP, and a movable accessory. The effect pattern for operating the effect 23 and the like, the effect pattern for operating the effect lever 701, the effect button 711, and the like by the player, and the like are included. The notice effect is executed in parallel with the variation display of the decorative symbol, and suggests that the symbol variation has a high jackpot reliability in which the symbol variation is stopped in the jackpot mode. The notice effect includes a notice effect that is executed before the reach state occurs (including the time when the reach occurs) in the process of displaying the variation of the decorative symbol, and a notice effect that is executed after the reach state occurs. Each notice effect has a different jackpot reliability, and basically, the notice effect displayed after the reach occurs has a relatively higher expectation of the jackpot than the notice effect displayed before the reach occurs. It's getting higher. The advance notice effect control means 9226 holds the advance notice lottery table referred to when selecting the advance notice effect pattern for each type of advance notice effect, and the advance notice according to the type of the advance notice effect generated according to the scenario of the variable effect pattern. The lottery table is selected. As specific types of notice effects, for example, comment notice effects, background notice effects, SU (step-up) notice effects, logo notice effects, mini character notice effects, group notice effects, character notice effects, etc. are prepared. ing. This advance notice effect is basically performed by synthesizing the display of one or a plurality of advance notice effects with the variable display of the decorative symbol on the effect display device 70. Therefore, even if the decorative pattern is variablely displayed by the same variable effect pattern, it is possible to generate various effect modes by combining with one or a plurality of advance notice effects.

The special game effect control means 9227 determines the content of the big hit medium effect (big hit effect pattern) for notifying that the big hit game is in progress. The jackpot middle production includes a jackpot start demo production that notifies the start of the jackpot game, a round production that notifies that the round game is in progress, and a jackpot end demo production that notifies the end of the jackpot game. When the special game effect control means 9227 receives the jackpot start demo command from the main control board 910, the jackpot medium effect pattern (big hit start demo effect pattern) is based on the information of the jackpot type stored in the sub-main information storage means 9260. , Round production pattern, jackpot end demo production pattern) is decided. In this jackpot production pattern, the jackpot start demo production time, the round production time (the production time according to the opening pattern of the jackpot 54), and the jackpot end demo production time are set, and along the time axis. A series of production contents are set. Further, the special game effect control means 9227 executes the jackpot start demo effect when the jackpot start demo command is received from the main control board 910 according to the jackpot effect pattern, and receives the round effect designation command as a trigger. Each round effect is executed, and the big hit end demo effect is executed when the big hit end demo command is received. In the jackpot start demo production, for example, the characters "big hit start" are displayed on the screen to announce the start of the jackpot game. Further, in the round effect, for example, the number of rounds currently being executed and the number of winning prize balls are displayed on the screen, and various images (animation images, etc.) that excite the big hit game are displayed. Then, in the big hit end demo effect, for example, the characters "big hit end" are displayed on the screen to notify the end of the big hit game, and the effect indicating the game state (mode) to be shifted to after that is displayed.

As described above, the effect controlling means 9220 generates image control commands related to images and sounds based on the determined effect contents (look-ahead effect pattern, variable effect pattern, notice effect pattern, stop symbol pattern, jackpot effect pattern, etc.). This is stored in the command storage area of the sub-main information storage means 9260.

The lamp control means 9230 controls the lighting, the emission color, and the like of the effect lamp LP according to the effect content set by the effect control means 9220. The lamp control means 9230 holds a plurality of types of lamp data (lamp pattern data) for controlling the lighting of the effect lamp LP, reads out the lamp data corresponding to the determined effect pattern, and reads the lamp control signal (the lamp control signal (). Lamp data) is transmitted to the lamp connection board 960.

The accessory control means 9240 controls the drive of the movable accessory according to the effect content set by the effect control means 9220. The accessory control means 9240 holds a plurality of types of drive data for driving and controlling the movable accessory, and transmits a drive control signal (drive data) corresponding to the determined effect pattern to the motor driver 970. Further, the accessory control means 9240 controls the effect operation unit 700 (effect lever 701, effect button 711).

The error effect control means 9250 is configured to determine an error effect pattern when an error effect designation command is received from the main control board 910, and notify the gaming machine that an error state has occurred according to the error effect pattern. There is.

The sub-main information storage means 9260 is configured to temporarily store decorative symbol information, variable effect pattern information, notice effect pattern information, control command information, and the like, and is predetermined for storing each information. It has a storage area. For example, in the command storage area, an effect control command buffer for storing an effect control command from the main control board 910, an image control command buffer for storing an image control command to the image control board 930, and an image control board 930. Contains an ACK command buffer to store ACK commands from. Each command buffer is composed of a ring buffer, and can store a predetermined number of effect control commands, image control commands, and ACK commands.

The command transmission / reception means 9270 is configured to receive the effect control command transmitted from the main control board 910 and store the effect control command in the effect control command buffer of the sub-main information storage means 9260. The command transmission / reception means 9270 generates an interrupt based on the input of the above-mentioned strobe signal from the main control board 910, executes reception interrupt processing (details will be described later) of the effect control command, and executes various effect control commands in this interrupt process. It is supposed to get. When the strobe signal is received, the command transmission / reception means 9270 preferentially performs the reception interrupt processing of this effect control command over other interrupt processing (interrupt processing of priority level 7 or less, which will be described later). ing.

Further, the command transmission / reception means 9270 is stored in the sub-main information storage means 9260 in order to indicate the execution of the effect content (variable effect pattern information, notice effect pattern information, decorative pattern information, etc.) set by the effect control means 9220. The transmitted image control command is transmitted to the image control board 930 by the serial communication method. As a general rule, the image control command is transmitted every predetermined cycle (500 μs in this example) according to the order set in the command storage area of the sub-main information storage means 9260. As a result, the image control board 930 analyzes various image control commands transmitted from the effect control board 920, and causes the effect display device 70 to variablely display the effect image including the decorative pattern according to the scenario of the variable effect pattern. , The notice effect is displayed in the form of being superimposed on the effect of the symbol variation at each stage of the variation display process. Further, the command transmission / reception means 9270 receives the ACK command transmitted from the image control board 930 and stores the ACK command in the ACK command buffer of the sub-main information storage means 9260.

[Various productions]
As described above, the pachinko gaming machine PM having such a configuration is configured so that various game effects are controlled and executed by the effect control board 920 and the image control board 930 according to the progress of the game and the like. .. In the following, among various game effects, the movable effect of the lever accessory 710 will be described with reference to FIGS. 39 and 40. FIG. 39 is a diagram for explaining an mode of the effect operation of the lever accessory 710, and FIG. 40 is a diagram schematically showing an effect operation pattern table of the lever accessory 710.

In the present specification, when comparing one number with the other number (for example, "more", "less", "different", etc.), one number or the other number is "0". It may include that there is. Also, when comparing the probability (ratio) of one execution with the probability (ratio) of the other execution (for example, "high", "low", "different", etc.), the probability (ratio) of one execution. ) Or the probability (ratio) of the other execution is "0%", and the probability (ratio) of one execution or the probability (ratio) of the other execution is 100%. Similarly, if one is more likely to be executed than the other, it includes the fact that the other is not executed at all (ie, the probability or percentage of execution of the other is 0%). Conversely, if one is less likely to be executed than the other, it includes that one is not executed at all (ie, the probability or percentage of execution of one is 0%).

The movable effect is an effect that suggests or notifies the high degree of expectation of a big hit by performing a predetermined effect operation (rotational operation, reciprocating operation) by the lever accessory 710 during the variable display of the symbol. This movable effect is performed as one of the game effects such as a notice effect or a look-ahead effect. It should be noted that this movable effect may be executed as an effect performed during a special game (big hit game, small hit game) or as an effect performed during a customer waiting demonstration.

In the present embodiment, a reciprocating motion (reciprocating motion pattern) and a rotary motion (rotating motion pattern) are set as the effect motion (effect motion pattern) of the lever accessory 710. The effect operation (reciprocating operation, rotation operation) of the lever accessory 710 is performed with the upper rotation reference position, which is the uppermost end of the rotation range (on the rotation circumference) of the lever accessory 710, as the starting point of the operation.

In the reciprocating operation, as shown in FIG. 39 (A), the lever accessory 710 alternately switches the rotation direction between the clockwise direction and the counterclockwise direction within a predetermined angle range, thereby shifting the lever accessory 710 in the left-right direction. It is a production operation to move back and forth. As the predetermined angle range, for example, a range of 30 degrees is set. As shown in FIG. 40, the reciprocating operation pattern of the lever accessory 710 includes a reciprocating operation pattern PX1 in which the lever accessory 710 reciprocates 5 times and a reciprocating operation pattern PX2 in which the lever accessory 710 reciprocates 10 times. There is.

As shown in FIG. 39B, the rotation operation is an effect operation in which the lever accessory 710 continuously rotates in a predetermined rotation direction (clockwise direction or counterclockwise direction). As shown in FIG. 40, the rotation operation patterns of the lever accessory 710 include a rotation operation pattern PY1 in which the lever accessory 710 rotates once, a rotation operation pattern PY2 in which the lever accessory 710 rotates twice, and a lever accessory 710. There are a rotation operation pattern PY3 in which the lever accessory 710 rotates 5 times, a rotation operation pattern PY4 in which the lever accessory 710 rotates 5 times, and a rotation operation pattern PY5 in which the lever accessory 710 rotates 7 times.

In the present embodiment, the larger the operating range required for the effect operation of the lever accessory 710, the higher the jackpot expectation, while the smaller the operating range required for the effect operation of the lever accessory 710, the relative the jackpot expectation. It becomes low. Specifically, the lever accessory 710 is more than the reciprocating operation patterns PX1 to PX2 in which the operation range of the lever accessory 710 is within a predetermined angle range (range of 30 degrees on the rotation circumference) on the rotation circumference. The jackpot expectation is set relatively higher in the rotation operation patterns PY1 to PY5 in which the operation range of is the entire range on the rotation circumference (the range of 360 degrees on the rotation circumference).

Further, in the present embodiment, the larger the movement amount (movement amount) of the lever accessory 710 in one production operation, the higher the expectation of big hit, while the operation amount of the lever accessory 710 in one production operation (movement amount). The smaller the amount of movement), the lower the expectation of a big hit. The operating amount (moving amount) of the lever accessory 710 is an operating distance (moving distance) at which the lever accessory 710 actually operates in one effect operation.

Specifically, in the reciprocating motion pattern, when the number of reciprocations is 5, the amount of motion is 300 degrees (30 degrees x 5 times x reciprocation), and when the number of reciprocations is 10, 600 degrees (30 degrees x). 10 times x round trip). Therefore, in the present embodiment, the expectation of a big hit increases in the order of reciprocating operation pattern PX1 (reciprocating 5 times) <reciprocating operation pattern PX2 (reciprocating 10 times).

On the other hand, in the rotation operation pattern, when the rotation number is 1 rotation, the operation amount is 360 degrees (360 degrees x 1 rotation), and when the rotation number is 2 rotations, the operation amount is 720 degrees (360 degrees x 2 rotations). ), 1080 degree movement amount (360 degrees x 3 rotations) in the case of 3 rotations, 1800 degree movement amount (360 degrees x 5 rotations) in the case of 5 rotations, 7 rotations The amount of movement is 2520 degrees (360 degrees x 7 rotations). Therefore, in the present embodiment, the rotation operation pattern PY1 (rotation 1 time) <rotation operation pattern PY2 (rotation 2 times) <rotation operation pattern PY3 (rotation 3 times) <rotation operation pattern PY4 (rotation 5 times) <rotation operation pattern The jackpot expectation increases by one step in the order of PY5 (7 rotations). When the rotation operation pattern PY5 is selected (when the effect operation of rotating the lever accessory 710 7 times is executed), the lever accessory 710 is rotated the number of times having a special meaning of "7". Based on this, the jackpot winning may be confirmed, or it may be suggested or notified that the jackpot expectation is extremely hot.

When the operating amount (moving amount) of the lever accessory 710 is the same, or when the operating amount (moving amount) of the lever accessory 710 is different, the faster the operating speed of the lever accessory 710, the higher the expectation of a big hit. On the other hand, the slower the operating speed of the lever accessory 710, the lower the expectation of a big hit. For example, when the movement amount (movement amount) of the lever accessory 710 is the operation amount for one rotation (360 degrees), the lever is more than the rotation operation pattern in which the lever accessory 710 rotates at the first rotation speed. The rotation operation pattern in which the accessory 710 rotates at the second rotation speed, which is faster than the first rotation speed, has a higher expectation of a big hit. Similarly, when the amount of movement (movement amount) of the lever accessory 710 is the amount of operation for five round trips (300 degrees), the reciprocating operation pattern in which the lever accessory 710 reciprocates at the first reciprocating speed is higher than that of the reciprocating operation pattern. The big hit expectation is higher in the reciprocating operation pattern in which the lever accessory 710 reciprocates at the second reciprocating speed faster than the first reciprocating speed.

Further, the effect operation (rotational operation, reciprocating operation) of the lever accessory 710 may be executed as a continuous effect performed over a plurality of variable displays. The continuous effect is executed over a plurality of variable displays until the operation holding ball (referred to as “trigger holding ball”) to be read ahead is digested. Whether or not this continuous effect can be executed and the execution pattern are determined by a look-ahead lottery. This look-ahead lottery is executed when a new operation hold ball is stored. This new operation-reserved ball is an operation-reserved ball with a special symbol of the person who is the main player of the game in the current game state. That is, when the current gaming state is the normal gaming state, the operation holding ball of the first special symbol is subject to the look-ahead lottery, and when the current gaming state is the time-saving gaming state or the probabilistic gaming state, the second special symbol The operation hold ball is subject to the look-ahead lottery. Here, as a condition for executing the look-ahead lottery, for example, (1) there is one or more action-holding balls (referred to as "preceding hold balls") before the action-holding ball to be read-ahead. , (2) All of the preceding reserved balls have fluctuation patterns of non-reach type (shortening fluctuation, normal fluctuation, etc.), (3) Continuous production is not already being executed (in the state where the look-ahead lottery is being won). Not) and so on. When this execution condition is satisfied, a look-ahead lottery is executed for the operation-holding ball to be read-ahead, and whether or not the continuous effect can be executed and its execution pattern (continuous effect pattern) are determined. In the present embodiment, at the start of each variation display during this continuous production, the lever accessory 710 is rotated or reciprocated, and the variation display when the operation holding ball to be read ahead is digested becomes a big hit. Expectations may be suggested or communicated. Immediately before changing the display mode of the holding image displayed in the holding image display area 71 of the screen or the changing image displayed in the changing image display area 73, the lever accessory 710 is produced (rotating operation, reciprocating). (Operation) to incite that the display mode of the hold image or the changing image changes (the hold change effect is executed) or the hold image or the changing image changes to the display mode with a high degree of expectation. You may. Regarding the degree of expectation of the hold change in this look-ahead effect (the degree of expectation that the display mode of the hold image or the changing image changes, or the degree of expectation that the hold image or the changing image changes to the display mode of a high degree of expectation). , The same configuration as the jackpot expectation suggested by the effect operation performed during the above-mentioned variation display can be applied (for example, the rotation operation has a higher expectation of pending change than the reciprocating operation, and one rotation. The expectation of pending change is higher in the two-rotation rotation operation than in the rotation operation of.

Further, as the effect operation pattern of the lever accessory 710, an effect operation pattern in which the lever accessory 710 rotates and then reciprocates, or an effect operation pattern in which the lever accessory 710 reciprocates and then rotates may be provided. When such a complex effect operation pattern is executed, the jackpot expectation is set to be higher than when the effect operation pattern in which only the rotation operation or the reciprocating operation is performed once is executed. You may.

Further, the effect lever 701 can be tilted from the initial tilt position to the maximum tilt position when the rotation position of the lever accessory 710 is in the upper rotation reference position or the lower rotation reference position. The expectation of a big hit suggested or notified when the effect lever 701 is tilted when the lever accessory 710 is in the lower rotation reference position than when the rotation position of the object 710 is in the upper rotation reference position. Is configured to be high. At this time, the lever accessory 710 operates in a direction opposite to the predetermined rotation direction (for example, counterclockwise) than when the lever accessory 710 operates from the upper rotation reference position to the lower rotation reference position in a predetermined rotation direction (for example, clockwise direction). When operating from the upper rotation reference position to the lower rotation reference position in the clockwise direction), the jackpot suggested or notified when the effect lever 701 in the state where the lever accessory 710 is in the lower rotation reference position is tilted. It may be configured so that the degree of expectation is high.

As described above, according to the present embodiment, by associating the operating range of the lever accessory 710 with the jackpot expectation, it is suggested or notified that the larger the operating range of the lever accessory 710 is, the higher the jackpot expectation is. , The player's interest can be strongly attracted to the movement of the lever accessory 710, and the effect of the two effects (reciprocating operation and rotation operation) can be further enhanced.

It may be equipped with two or more large winning openings, that is, a first large winning opening and a second large winning opening that does not have this specific area (probability fluctuation function operating area, V area). As an example of the board layout, the first large winning opening and the second large winning opening may be arranged substantially vertically or horizontally side by side in the right side area of the game area, or the first large winning opening may be arranged. The board area to be created and the board area in which the second large winning opening is arranged may be different areas. In that case, the number of prize balls (unit number of prize balls) paid out when the game ball enters the first big prize opening and the number of prize balls paid out when the game ball enters the second big winning opening. The number of prize balls (unit number of prize balls) may be the same or different. Of the two big winning openings, the first major winning opening (or the second major winning opening) is for the big winning opening for small hit games, and the second big winning opening (or the first big winning opening) is for big hit games. It may be configured as a big winning opening. In that case, even if the number of prize balls (unit prize balls) of the big prize opening for small hit games is 10, the number of prize balls (unit prize balls) of the big prize openings for big hit games is 15. good.

<Modification example 3 of a gaming machine>
In the above-described embodiment, the function for shortening the fluctuation time of the special symbol is divided into the function for shortening the fluctuation time of the first special symbol and the function for shortening the fluctuation time of the second special symbol, and the latent probability change game state is set as the probability of the special symbol. It may be defined as a gaming state in which the variation function and the variation time shortening function of the second special symbol are activated and the electric chew support function is not activated. In addition, even if the electric chew support function operates in synchronization with the special symbol fluctuation time shortening function (second special symbol fluctuation time shortening function), the special symbol fluctuation time shortening function (second special symbol fluctuation time) It may operate independently of the shortening function).

Next, in order to make it easier to clearly understand the technical significance of the embodiments and modifications, the problems corresponding to the embodiments and modifications will be outlined.
