Description

  The present invention relates to a gaming machine.

  A pachinko gaming machine, which is a type of gaming machine, includes a gaming board, and a game ball is launched into a gaming area configured in front of the gaming board. Then, when a game ball is won in various winning holes provided in the game area, a predetermined number of game balls are paid out. In addition, in the gaming machine, there is one in which a symbol display device for displaying a variable display of symbols and various effects is installed in the approximate center of the game board (for example, see Patent Document 1).

  In such a gaming machine, the variable display of the symbols on the symbol display device is started with the winning of the predetermined winning opening as a trigger, and then stopped after the variable display by the predetermined pattern. Various effects are displayed during variable display of the symbol. As this effect, there is a reach effect displayed when the variably displayed symbol becomes reach display. Then, according to the stop symbol, a special game state (a big hit state) or the like is entered, and a privilege such as payout of a large amount of game balls is given.

  In recent years, instead of installing a symbol display device at the approximate center of the game board, the game board and the symbol display device are arranged side by side so that the symbol display device is on the back side, and the display area of the symbol display device There is known a pachinko gaming machine that can be visually recognized through a game board (for example, see Patent Document 2). In such a gaming machine, the display area of the symbol display device can be secured wider than, for example, a gaming area, and the display area can be greatly expanded as compared with a conventional gaming machine. Thereby, various effects can be displayed dynamically.

  However, if the game machine is configured such that the variable display of symbols is always performed over the entire display area, it is necessary for the player to always visually recognize the entire display area, and the visibility may deteriorate. In addition, for example, when the variable display of the symbol is a normal display, it is displayed in a part of the display region, and when the variable display of the symbol is a reach display, the reach effect is displayed in the entire display region. It is thought that the reach production is emphasized and the player's attention can be increased.

  However, in the configuration in which the design variable display area in the display area is increased or decreased, it is necessary to divide the display area in the reduced display so that the player can clearly be instructed to the player. In this case, since the division becomes unnecessary in the enlarged display, it is not preferable to attach a division line or the like to the display screen of the game board or the symbol display device.

  Hereinafter, effective means for solving the above-described problems will be described while showing effects and the like as necessary. In the following, for easy understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses, but is not limited to the specific configuration shown in parentheses.

Means 1. A game board (game board unit 100) provided at a position visible from the front of the gaming machine;
A plurality of nails (nails 120) are provided on the front surface of the game board, which are partitioned and provided by rails (inner rail member 101, outer rail member 102) for guiding game balls, and change the flow direction of the game balls guided by the rails. An arranged game area (game area 103);
A display device (symbol display device 160) provided on the back side of the game board and having a display area (display screen 161) in a position aligned with the game area in the front-rear direction;
Display control means (display control board 278) for controlling the display device so as to start variable display of a picture in the display area when a predetermined start condition is satisfied;
In a gaming machine configured such that the display area is visible through the gaming board,
The display control means enlarges the display mode in the display area from a reduced display that variably displays the pattern in a part of the display area to a variable display of the pattern in an area wider than the reduced display. Display mode switching means for switching to display (enlarged display processing S703 of the display control board 278),
Furthermore, the game board
A gaming area forming board (game area forming board 110) having the gaming area formed and having transparency;
A light guide plate (light guide plate 150) provided on the back side of the game area forming plate and having transparency;
A light emitter (LED 154 for light guide plate) provided on at least a part of the outer periphery of the light guide plate and introducing light into the light guide plate;
The light guide plate is provided on at least one of a front surface or a back surface of the light guide plate so as to partition a region where the reduced display is performed in the display region, and transmits light that is introduced from the light emitter and reflected inside. A light emission region (uneven portion 157) that radiates by irregular reflection is provided,
A gaming machine comprising: a light emission control means (audio lamp control board 272a) for switching the light emitter from an on state to an off state when the display mode is switched by the display mode switching unit.

  In the gaming machine, a gaming board is provided at a position that can be viewed from the front of the gaming machine, and the gaming board is partitioned by rails to form a gaming area. The game ball guided by the rail collides with the nail and flows down the game area while changing direction. There is a display device on the back side of the game board, and the display content in the display area of the display device is visible through the game board. In such a configuration in which the game board and the display device are arranged side by side in front and back, the display area can be expanded as compared with the conventional case. As this expansion, for example, the display area can be expanded to be equal to or greater than the game area. Thereby, the display contents in the display area become dynamic.

  In this case, according to the means 1, since the display mode in the display area is switched from the reduced display to the enlarged display, for example, in the normal variable display of the picture, the reduced display is performed and the specific reach effect is performed. By adopting a configuration in which enlarged display is performed, the display mode can be improved in a configuration in which the display area is expanded.

  In addition, the game board includes a light guide plate on the back side of the game area forming plate, and a light emission area is formed on the light guide plate so as to partition an area where reduced display is performed. And the light irradiated from the light-emitting body and introduced into the light guide plate reaches the light emission region and is emitted from the light guide plate. As a result, a partition line is displayed so as to partition the reduced display area, and the area can be clearly taught. In particular, in this configuration, the dividing line is not represented in the display area, but is represented by the light emitted from the light guide plate, so that the effect taught above can be made more remarkable. This is because the visibility of the player is different between the pattern displayed in the display area and the light emitted from the light guide plate.

  When the display mode in the display area is switched from the reduced display to the enlarged display, the light emitter is switched from the on state to the off state. Thus, the division line disappears while the enlarged display is being performed, and the enlarged display is not disturbed by the division line in the configuration in which the area that is reduced and displayed as described above is clearly taught.

  In addition, the above effect can be suitably achieved by forming the game area on the game area forming plate instead of forming the game area on the light guide plate. That is, in the configuration in which the game area is formed on the light guide plate, it is necessary to dispose the nail on the front surface of the light guide plate. In this case, light may leak out from the position where the nail is disposed, and the amount of light reaching the light emitting area may be reduced. On the other hand, such a disadvantage does not occur by forming the game area on the game area forming plate as described above.

  In addition, it is preferable that the “light emission region” is formed by unevenness. In this case, when the light reflected in the light guide plate reaches the light emission region, the incident angle becomes smaller than the critical angle so that the light is transmitted through the light emission region or diffusely reflected in the light emission region. As a result, light is emitted from the light guide plate to the front of the gaming machine. With this configuration, the light emission region can be formed relatively easily and at a relatively low cost. In addition, by adopting a configuration in which the unevenness is mechanically formed, the light emission region can be formed more easily.

  In the “reduced display”, a background image or the like may be displayed outside the region where the variable display of the pattern is performed. Moreover, it is good also as a structure which displays a character etc. in this background image.

  In addition, the “light emission region” is “formed in a frame shape so as to divide the region where the reduced display is performed in the display region”, whereby the region where the reduced display is performed can be taught more clearly.

Mean 2. In means 1, the game board includes a stage for rolling a game ball (stage 144), and a guide path for guiding the game ball flowing down the upper part of the game area to the stage (front side ball path 132, rear side). A center frame (center frame 130) having a ball passage 143);
The center frame is formed of a transparent material so as to partition an area where the reduced display is performed in the display area,
A gaming machine, wherein the light emitting area is formed along the center frame.

  In the gaming machine of the means 2, when the game ball flowing down the upper part of the game area enters the guide passage, the game ball is guided to the stage, and after rolling on the stage, is discharged to the game area. Thereby, the behavior of the game ball in the game area is diversified. In such a configuration, since the center frame is formed of a transparent material, it is possible to prevent the pattern displayed in the display area from being visually recognized by the center frame in the configuration provided with the center frame.

  Further, the center frame is formed so as to partition an area where the reduced display is performed in the display area. As a result, in a situation where the reduced display is performed, since the variable display of the pattern is performed within the area partitioned by the center frame, the display mode in the conventional gaming machine is reproduced. In other words, a conventional gaming machine generally has a configuration in which a picture display device is installed at the approximate center of the game board, and a center frame is installed so as to surround the picture display device. In this case, by performing the reduced display within the area partitioned by the center frame as described above, the player who is used to the conventional game machine can visually recognize the variable display of the pattern during the reduced display without a sense of incongruity. it can. On the other hand, in the enlarged display, the pattern is displayed beyond the area partitioned by the center frame. Therefore, the enlarged display can be emphasized more.

  The light emitting area is formed along the center frame. Thereby, the division line is expressed along the center frame, and in the configuration in which the center frame is formed of the transparent material, it is possible to clearly teach the reduced display displayed in the area partitioned by the center frame. . Further, the dividing line is represented by the light emitted from the light guide plate (light emitting area) on the back side of the game area forming plate, so that the dividing line is located at a position near the center frame in the front-rear direction. The occurrence of inconvenience that the center frame and the partition line are shifted depending on the viewing angle can be suppressed.

  Means 3. In the means 1 or 2, the gaming machine is characterized in that the light guide plate is arranged on the back side of the game area forming plate so as to overlap or be close to the game area forming plate.

  According to the means 3, the thickness dimension of the game board can be made as small as possible, and the space required for providing the game board can be reduced. Moreover, a lane marking is represented at a position where the distance in the front-rear direction is close to the game area. For example, in a configuration in which the game area forming plate and the light guide plate are largely separated from each other, the dividing line and the game area are separated from each other. In particular, in the configuration provided with the means 2 described above, the lane marking can be expressed at a position where the distance in the front-rear direction is close to the center frame, and the center frame and the lane marking may be shifted depending on the viewing angle. Occurrence can be suppressed.

  Means 4. A game machine according to any one of means 1 to 3, wherein the light emitting area is formed on a surface of the light guide plate facing the game area forming plate.

  According to the means 4, the division line is represented at a position where the distance in the front-rear direction is closer to the game area. For example, in the configuration in which the light emitting area is formed on the surface opposite to the surface facing the game area forming plate, the dividing line and the game area are at least separated by the thickness of the light guide plate. In particular, in the configuration provided with the means 2 described above, the lane marking can be expressed at a position where the distance in the front-rear direction is close to the center frame, and the center frame and the lane marking may be shifted depending on the viewing angle. Occurrence can be suppressed.

Means 5. In any one of means 1 to means 4, the game board is provided with a ball entering portion (general winning port 113, variable winning device 114, operating port 115) into which a game ball flowing down the game area enters,
The game area forming plate and the light guide plate are provided with through holes (through holes 152a to 152i) that allow the game balls that have entered the ball-entry portion to pass to the back side of the game board,
A gaming machine, wherein a discharge passage (discharge passage 171) for discharging the game ball that has passed through the through hole to the outside of the gaming machine is provided between the game board and the display device.

  In the gaming machine of the means 5, the game ball that has entered the entrance portion passes through the through holes formed in the game area forming plate and the light guide plate and reaches the back side of the game board. The game ball is discharged to the outside of the gaming machine via a discharge passage provided between the game board and the display device. By adopting such a configuration, it is possible to smoothly discharge the game balls that have entered the entrance portion without complicating the shape of the display device.

  However, in this configuration, the game board and the display device are separated forward and backward. Therefore, in the configuration provided with the means 2 described above, if it is intended to represent the lane markings for reduced display in the display area, it is difficult to display the lane markings along the center frame. This is because a player who plays a game on this gaming machine has various positions of eyes with respect to the game area, and if the center frame and the dividing line are separated from each other in the front and rear, they do not match depending on the viewing angle. On the other hand, the above-mentioned inconvenience is caused by having the configuration of the above-described means 1 and the dividing line being represented by the light emitted from the light guide plate (light emission region) on the back side of the game region forming plate. Will not occur.

Means 6. In any one of the means 1 to 5, the game board enters a game ball that flows down the game area at a position near a lower end of the game area and below the light emission area. A plurality of sections (general winning port 113, variable winning device 114, operating port 115),
The game area forming plate and the light guide plate are provided with through holes (through holes 152a to 152i) that allow the game balls that have entered the ball entry portion to pass to the back side of the game machine,
A gaming machine, wherein the light emitter is provided so as to introduce light into the light guide plate from a position above the through hole.

  In the gaming machine of the means 6, since a plurality of ball entering portions are provided at positions near the lower end of the game area, the ball entering the ball entering portion occurs as a result of flowing down the game area. Then, the game ball that has entered the entrance portion passes through the through holes formed in the game area forming plate and the light guide plate and reaches the back side of the game board. Then, the game ball is discharged to the outside of the gaming machine through a discharge passage or the like.

  In this case, the light emitter is provided so as to introduce light into the light guide plate from a position above the through hole. Thereby, the light introduced into the light guide plate reaches the light emission region without being obstructed by the through hole or the like. Therefore, in the above configuration, the light emission from the light emission region can be improved.

  Mean 7 A gaming machine, wherein means 5 or means 6 is provided with light reflecting means (light reflecting tape 158) so as to cover a peripheral wall portion of a through hole provided in the light guide plate.

  According to the means 7, the light reaching the peripheral wall portion of the through hole is reflected by the light reflecting means and travels through the light guide plate. Therefore, in the configuration in which the through hole is provided in the light guide plate, it is possible to suppress the amount of light reaching the light emission region from being reduced.

  Further, in a configuration in which the peripheral wall portion of the through hole is not covered by the light reflecting means, the light reflected inside the light guide plate is irradiated to the game ball passing through the through hole, and the reflected light on the surface of the game ball is reflected in the light emission region It is conceivable that it is confused with the light emitted through the. In this case, there is a possibility that inconveniences such as blurring of lane markings or deterioration of the visibility of the pattern displayed in a reduced size may occur. On the other hand, since the peripheral wall portion of the through hole is covered with the light reflecting means, it is possible to suppress the occurrence of the above inconvenience.

  Means 8. In any one of the means 1 to 7, a peripheral surface light reflecting means (light reflecting tape 159) is provided so as to cover an area of the outer periphery of the light guide plate excluding a portion where the light emitter is provided. A gaming machine characterized by

  According to the means 8, the light that has reached the outer periphery of the light guide plate is reflected by the peripheral surface light reflecting means and travels through the light guide plate. Therefore, it is possible to prevent light reaching the outer periphery of the light guide plate from leaking from the light guide plate, and to reduce the amount of light reaching the light emission region.

  Means 9. A gaming machine according to any one of means 1 to 8, wherein a thickness dimension of the light guide plate is made smaller than that of the game area forming plate.

  Since a game area is formed and a nail is disposed on the game area forming plate, it is necessary to ensure a sufficient thickness dimension of the game area forming plate so that the nail can be supported in a stable state. On the other hand, the light guide plate is not provided with nails. In such a case, according to the means 9, since the thickness dimension of the light guide plate is smaller than that of the game area forming plate, the thickness dimension of the game board can be reduced as much as possible, and the space required for providing the game board can be reduced. Is achieved.

  Means 10. A gaming machine according to any one of means 1 to 9, wherein a fixture (screw 112) for fixing the game area forming plate and the light guide plate is provided on the outer peripheral side of both.

  According to the means 10, the game area forming plate and the light guide plate are fixed by the fixtures, and these are unitized to form a game board. In this case, since it is the structure which provides a fixing tool in each outer peripheral side of a game area | region formation board and a light-guide plate, the said unitization can be performed favorably. For example, in the configuration in which an adhesive is applied to the opposing surfaces of the game area forming plate and the light guide plate and fixed, bubbles or the like may be generated inside and the defect rate may increase.

Means 11. In any one of the means 1 to 10, the display control means includes display mode return means (reduced display processing S705 in the display control board 278) for returning the display mode from the enlarged display to the reduced display.
The light emission control means switches the light emitter from an off state to an on state when the display form is restored by the display form restoration means.

  According to the means 11, when the display mode in the display area is returned from the enlarged display to the reduced display, the illuminator is switched on and the dividing line appears again. Therefore, when returning from the enlarged display to the reduced display, the reduced display is clearly taught.

In particular, in this configuration, the dividing line is not represented in the display area, but is represented by the light emitted from the light guide plate, so that the effect taught above can be made more remarkable. This is because the visibility of the player is different between the pattern displayed in the display area and the light emitted from the light guide plate.

  In addition, the above effect can be suitably achieved by forming the game area on the game area forming plate instead of forming the game area on the light guide plate. That is, in the configuration in which the game area is formed on the light guide plate, it is necessary to dispose the nail on the front surface of the light guide plate. In this case, light may leak out from the position where the nail is disposed, and the amount of light reaching the light emitting area may be reduced. On the other hand, such a disadvantage does not occur by forming the game area on the game area forming plate as described above.

  In addition, it is preferable that the “light emission region” is formed by unevenness. In this case, when the light reflected in the light guide plate reaches the light emission region, the incident angle becomes smaller than the critical angle so that the light is transmitted through the light emission region or diffusely reflected in the light emission region. As a result, light is emitted from the light guide plate to the front of the gaming machine. With this configuration, the light emission region can be formed relatively easily and at a relatively low cost. In addition, by adopting a configuration in which the unevenness is mechanically formed, the light emission region can be formed more easily.

  In the “reduced display”, a background image or the like may be displayed outside the region where the variable display of the pattern is performed. Moreover, it is good also as a structure which displays a character etc. in this background image.

  In addition, the “light emission region” is “formed in a frame shape so as to divide the region where the reduced display is performed in the display region”, whereby the region where the reduced display is performed can be taught more clearly.

  Moreover, the effect of each means can be exhibited by applying any one of the means 2 to 12 to the means 14, and the present invention can be made more suitable.

In addition, on the left and right sides of the central illumination unit 34, a prize ball lamp 36 that is turned on during the payout of a prize ball and an error display lamp 37 that is turned on at a predetermined error are provided.

  The front door frame 13 is provided with a ball rental operating portion 40 at a position below the window portion 31. The ball lending operation unit 40 is provided with a ball lending button 41, a return button 42, and a frequency display unit 43. The ball lending operation, the card return operation, and the card frequency can be confirmed by the ball lending operation unit 40 in a state where bills or cards are inserted into the CR unit disposed on the side of the pachinko machine 10. That is, the ball lending button 41 is operated to obtain a lending ball based on information recorded on a card or the like (recording medium), and the lending ball is paid out as long as there is a remaining amount on the card or the like. The return button 42 is operated when requesting the return of a card or the like inserted into the CR unit. The frequency display unit 43 displays remaining amount information such as a card. In a pachinko machine (so-called cash machine) in which game balls are lent out directly from a ball lending device or the like without using a CR unit, the ball lending operation unit 40 is not necessary. A decorative sticker or the like is attached to 40 installation parts. Thereby, in the configuration of the present pachinko machine 10 provided with the lending operation unit 40, the pachinko machine using the CR unit (so-called CR machine) and the cash machine can be shared.

  The main body frame 12 includes a resin base 25 whose outer shape is substantially the same as that of the outer frame 11, and a game ball launching mechanism 50 is attached to the lower portion of the resin base 25. The game ball launching mechanism 50 includes a metal plate 51 as a base member, and an electromagnetic solenoid 52 and a launch rail 53 are attached to the metal plate 51.

In this case, the solenoid 52 is arranged so that the output shaft protrudes obliquely upward to the left when energized, and the game ball launched by the solenoid 52 moves on the firing rail 53 and reaches a game area described later.

  A pair of left and right discharge ports 66 and 67 are formed on the left side of the launch rail 53 on the front surface of the main body frame 12, and the game balls discharged from the discharge ports 66 and 67 are placed in front of the upper plate 23 or the lower plate. A game ball guide unit 70 for guiding to any one of 16 is attached. For convenience, in the following description, the discharge port 66 is also referred to as a first discharge port, and the discharge port 67 is also referred to as a second discharge port. Basically, the game balls are discharged from the first discharge port 66, and when the passage leading to the upper plate 23 including the first discharge port 66 is filled with game balls, the second discharge port 66 is used instead of the first discharge port 66. The game balls are discharged from the outlet 67.

  The game ball guide unit 70 is formed with a ball discharge passage 71 for communicating the discharge ports 66 and 67 with the lower plate 16. In the game ball guide unit 70, a communication port 72 communicating with the upper plate 23 is formed on the front side of the first discharge port 66 of the main body frame 12, and an opening / closing plate 73 is attached so as to close the communication port 72. ing. The opening / closing plate 73 is rotatably supported by a support shaft 74 and is always urged to a position where the communication port 72 is closed by a spring 75 as urging means.

  According to the above configuration of the game ball guide unit 70, the open / close plate 73 rises as shown in the figure by the urging force of the spring 75 when the front door frame 13 is opened, and the communication port 72 is closed. In this state, the game ball discharged from the first discharge port 66 is guided to the lower plate 16 through the ball discharge passage 71. Therefore, when the front door frame 13 is opened in a state where game balls are stored upstream of the communication port 72, the stored balls flow down to the lower plate 16 through the ball discharge passage 71 without spilling from the communication port 72. To do. In other words, even in the present pachinko machine 10 in which the front decorative frame is omitted and the upper plate 23 is directly provided on the front door frame 13, the game on the upstream side of the communication port 72 when the front door frame 13 is opened. The inconvenience of spilling a ball can be prevented. On the other hand, when the front door frame 13 is closed, the opening / closing plate 73 is pushed open against the biasing force of the spring 75 by a ball passage rod 76 (see FIG. 2) provided on the back surface of the front door frame 13. . In this state, the game ball discharged from the first discharge port 66 is guided to the upper plate 23 through the communication port 72. Accordingly, the game ball upstream of the communication port 72 is paid out to the upper plate 23. A lower plate full tank switch for detecting that the game ball discharged to the lower plate 16 is full (full tank) is attached to the downstream side of the ball discharge passage 71 of the game ball guide unit 70.

  A substantially circular window hole 26 is formed in a central portion of the resin base 25 and at a position aligned with the transparent panel 32 in the front-rear direction. The game board unit 100 is attached to the resin base 25 from the rear so that a part is exposed from the window hole 26. In addition, a symbol display device 160 is mounted on the resin base 25 so as to be positioned behind the game board unit 100.

  Next, the game board unit 100 and the symbol display device 160 will be described. 4 is a perspective view of the game board unit 100 and the symbol display device 160, and FIG. 5 is a front view of the game board unit 100.

  An inner rail member 101 and an outer rail member 102 for guiding the game balls launched from the game ball launching mechanism 50 to the upper part of the game board unit 100 are attached to the front surface of the game board unit 100. The front surface of the game board unit 100 is partitioned by inner and outer rail members 101 and 102, and a game area 103 is formed in an inner area partitioned in a substantially circular shape. And as above-mentioned, this game area 103 can be visually recognized from the front via the transparent panel 32 from the front.

  The symbol display device 160 is disposed on the back side of the game board unit 100 and is separated from the game board unit 100. Thereby, a predetermined space is secured between the game board unit 100 and the symbol display device 160, and various members to be described later are arranged on the back side of the game board unit 100 using the space (see FIG. 9). ). The symbol display device 160 is composed of a liquid crystal display device, and has a display screen 161 that displays variable display of symbols and various effects. The display screen 161 has a larger area than the game area 103, and the symbol display device 160 is arranged so that the entire game area 103 is included in the display screen 161 when viewed from the front. This display screen 161 is visible through the game board unit 100.

  Here, the game board unit 100 will be described in detail. 6 is a perspective view of the game board unit 100 as viewed from the rear, FIGS. 7 and 8 are exploded perspective views of the game board unit 100, and FIG. 9 is a longitudinal sectional view of the game board unit 100.

  As shown in FIG. 8, the game board unit 100 includes a game area forming plate 110 and a light guide plate 150. The game area forming plate 110 and the light guide plate 150 have substantially the same substantially rectangular shape, and are fixed so that their opposing surfaces come into contact with each other. Specifically, openings 111 and 151 are formed on the same axis at the four corners of each of the plates 110 and 150, and screws 112 are inserted into and fixed to the respective openings 111 and 151 communicated. .

  The game area forming plate 110 is made of a colorless and transparent polycarbonate resin, and the above-described game area 103 is formed on the front surface thereof. The light guide plate 150 is made of a colorless and transparent acrylic resin. The game area forming plate 110 and the light guide plate 150 are formed with a plurality of large and small through holes (the light guide plate 150 is indicated by reference numerals 152a to 152i) penetrating in the front-rear direction at corresponding positions (FIG. 8). Each of the through holes is provided with a general winning port 113, a variable winning device 114, an operating port 115, a through gate 116, and a center frame 130, respectively.

  In detail, the center frame 130 is disposed at the approximate center of the game area 103, the operation port 115 is disposed below the center frame 130, and the variable winning device 114 is disposed below the operation hole 115. In addition, through gates 116 are arranged on both the left and right sides of the center frame 130, and general winning holes 113 are arranged on both lower sides of the game area 103 (three on the left side and one on the right side). ). When a game ball enters the general winning port 113, the variable winning device 114, and the operation port 115, it is detected by a detection switch, and a predetermined number of prize balls are placed on the upper plate 23 (in some cases, the lower plate 16) based on the detection result. To be paid out.

  In addition, a first specific ramp portion 117 and a second specific ramp portion 118 are provided on the upper right side of the game area 103, and an out port 119 is provided at the lower end of the game area 103. The game balls that have not entered the various winning openings etc. are guided to the ball discharge path (not shown) through the out opening 119. In the game area 103, a large number of nails 120 are planted and a windmill 121 and the like are arranged in order to appropriately distribute and adjust the falling direction of the game balls. In this case, since the polycarbonate resin forming the game area forming plate 110 has a relatively high elasticity, when the game ball collides with the nail 120 or the like driven on the surface, the angle of the nail 120 is adjusted. In such a case, the game area forming plate 110 is not easily cracked. In addition, the length of a screw for fixing the variable winning device 114, the operation port 115, etc. to the game area forming plate 110, and the length of the nail 120 driven into the game area forming plate 110 are game area formation. The thickness is smaller than the thickness of the plate 110, and these screws and nails 120 do not reach the light guide plate 150 (see FIG. 9).

  The first specific lamp unit 117 is provided with red, green, and blue three-color emission type LED lamps on the inner side thereof. Then, the emission color is switched in a predetermined order using a winning at the operation port 115 as a trigger. Specifically, red light is turned on with a winning at the operation port 115 as a trigger, and the emission color is switched to green light when a predetermined time elapses in this state. Then, when the predetermined time elapses with the green light turned on, the emission color is switched to blue light. Thereafter, the emission color is repeatedly switched in the order of red, green, and blue until the emission color switching stop time comes. Thereby, red, green, and blue are repeatedly displayed in this order on the first specific lamp unit 117. And finally, when red or green is stopped and displayed, a big hit is generated, and when blue is stopped and displayed, no big win is generated. In addition, the type of jackpot is different between the case where the stop is finally displayed in red and the case where the stop is finally displayed in green, and the former has a jackpot that is more advantageous to the player.

  On the other hand, the second specific lamp unit 118 is provided with a red and green two-color light emission type LED lamp inside thereof. In the second specific lamp unit 118, the emission color is switched in a predetermined order with the passage of the game ball of the through gate 116 as a trigger. Specifically, when the game ball passes through the through gate 116, lighting of red light and lighting of green light are alternately performed. As a result, red and green are alternately displayed on the second specific lamp unit 118. And when red is stopped and displayed, it is comprised so that the electrically-driven accessory which accompanies the operating port 115 will be in an open state only for the predetermined time.

  The variable winning device 114 is normally in a closed state in which a game ball cannot be won or difficult to win, and is switched to a predetermined open state in which a game ball is easy to win in the case of a big win. More specifically, when the jackpot is generated, the variable winning device 114 is in a predetermined open state, and the game ball is easily won. As an opening mode of the variable prize winning device 114, a predetermined time (for example, 30 seconds) or a predetermined number (for example, ten) of winnings is defined as one round, and the following is performed on condition that the winning in the continuous prize winning opening in the variable prize winning device 114 is performed In general, the variable winning device 114 is repeatedly opened with a condition for transition to a round established, with a maximum of a plurality of rounds (for example, 15 rounds).

  The center frame 130 includes a roof frame 131 that forms an upper portion of the center frame 130 and a stage frame 140 that forms a lower portion of the center frame 130. The roof frame 131 and the stage frame 140 are made of a transparent material such as acrylic resin. By connecting these frames 131 and 140, the center frame 130 has a frame shape as a whole.

  The entire roof frame 131 has a groove shape that is opened rearward, and is fixed to the game area forming plate 110 so that the rearward opening portion is closed and a front-side ball passage 132 is formed. The front-side sphere passage 132 is formed on the left and right with an opening 133 formed in the upper part of the roof frame 131 as an entrance. Further, the left and right lower end portions 134 of the roof frame 131 extend rearward and pass through the through holes formed in the game area forming plate 110. These lower end portions 134 are connected to the stage frame 140, whereby the near-side ball passage 132 is communicated with the stage frame 140.

  The stage frame 140 includes a front stage member 141 and a rear stage member 142, both of which are assembled via through holes formed in the game area forming plate 110 and the light guide plate 150. The front stage member 141 is opened in the front-rear direction, whereas the rear stage member 142 has a groove shape that is entirely opened forward. Open portions of the left and right side portions of the rear stage member 142 are closed by the back surface of the light guide plate 150 to form a back side spherical passage 143. The back side ball passage 143 communicates with the front side ball passage 132. Further, the front stage member 141 and the rear stage member 142 form a stage 144 on which the game ball that has passed through the back side ball passage 143 rolls in the left-right direction.

  A rear guide portion 145 is formed at the center of the stage 144, and a front guide portion 146 is formed so as to sandwich the rear guide portion 145. The game ball that has been sufficiently decelerated to reach the rear guide portion 145 is guided to the guide passage 147 formed in the rear stage member 142 and is discharged from the guide passage 147 into the game area 103. In this case, the outlet of the guide passage 147 is positioned vertically above the operation port 115, and no obstructing member such as the nail 120 is disposed between them. Therefore, the game ball that has passed through the guide passage 147 can easily enter the operation port 115. On the other hand, the game ball that has been sufficiently decelerated to reach the front guide portion 146 is discharged into the game area 103 as it is.

  The movement of the game ball in the center frame 130 will be briefly described. The game ball that has entered the opening 133 of the roof frame 131 passes through either the left or right front side ball passage 132 and reaches the back side ball passage 143. The game ball that has reached the back side ball passage 143 passes through the back side ball passage 143 and reaches the stage 144. The game ball that has reached the stage 144 rolls left and right on the stage 144. As a result of the rolling, the game ball that has reached the rear guide portion 145 passes through the guide passage 147 and is guided toward the operation port 115. On the other hand, the game ball that has reached the front guide portion 146 is discharged into the game area 103 without being guided toward the operation port 115.

  In the above configuration, as shown in FIG. 6, the variable winning device 114, the operation opening 115, and the stage frame 140 of the center frame 130 protrude rearward from the back surface of the light guide plate 150. In this case, as described above, a predetermined space is secured between the game board unit 100 and the symbol display device 160, and the variable winning device 114 and the like protruding rearward do not come into contact with the symbol display device 160. Yes. In addition, the game balls that are launched into the game area 103 and enter the general prize opening 113, the variable prize winning device 114, and the operation opening 115 pass through through holes formed in the game area forming plate 110 and the light guide plate 150. It is led to the back side of 100. In this case, as shown in FIG. 9, a discharge passage unit 170 is provided between the game board unit 100 and the symbol display device 160, and the game ball guided to the back side is the discharge passage unit 170. It is discharged to the outside of the gaming machine through the discharge passage 171 formed in the above.

  Next, the light guide plate 150 will be described in detail. FIG. 10 is a front view of the light guide plate 150, and FIG. 11 is an explanatory diagram for explaining a light path in the light guide plate 150.

  On the upper edge of the light guide plate 150, a plurality of recesses 153 that are recessed downward and penetrate in the thickness direction are formed at predetermined intervals over the entire upper edge. The element substrate 155 is disposed so that the light emitting diodes 154 (hereinafter referred to as light guide plate LEDs 154) are positioned in the recesses 153. Specifically, the element substrate 155 has a long shape so as to be located over the entire upper edge of the light guide plate 150, and a plurality of light guide plate LEDs 154 are formed at predetermined intervals in the longitudinal direction. This predetermined interval corresponds to the interval between the recesses 153.

  The light guide plate LED 154 emits colored (for example, blue) visible light, and the irradiated light is introduced into the light guide plate 150. In this case, a light reflecting tape 156 is attached to the upper edge of the light guide plate 150 so as to cover the recess 153 penetrating in the thickness direction. Thereby, the light of the LED 154 for the light guide plate is surely introduced into the light guide plate 150. The introduced light basically repeats total reflection in the light guide plate 150. That is, the introduced light is incident on the outer surface of the light guide plate 150 at an incident angle larger than the critical angle with respect to the normal line of the outer surface of the light guide plate 150 and repeats total reflection.

  On the front surface of the light guide plate 150, fine linear irregularities (uneven portions 157) are formed by mechanical etching, and the uneven portions 157 form a frame-like pattern as shown in FIG. Has been. This pattern is formed along the inner peripheral portion of the frame-shaped center frame 130. As described above, the light that is introduced from the LED 154 for the light guide plate and totally reflected in the light guide plate 150 reaches the concavo-convex portion 157 to change the incident angle as shown in FIG. A part of the light whose incident angle has changed is emitted from the front side. The emitted light passes through the game area forming plate 110. Thereby, the frame-shaped pattern corresponding to the uneven part 157 appears to shine in color. In FIG. 11, the dimension of the concavo-convex part 157 with respect to the thickness dimension of the light guide plate 150 is shown larger than the actual size. 8 and 10 show a state where light is introduced from the LED 154 for the light guide plate.

  As shown in FIG. 10, the peripheral wall portions of the plurality of through holes 152 a to 152 i formed in the light guide plate 150 are covered with the light reflecting tape 158. Further, the lower and left and right peripheral surfaces of the light guide plate 150 where the element substrate 155 is not provided are also covered with the light reflecting tape 159. Thereby, even if the light totally reflected in the light guide plate 150 reaches the peripheral wall portions of the through holes 152a to 152i and the peripheral surface of the light guide plate 150, the light reflection tape 158, 159 does not leak out so much. It will be reflected. Therefore, light easily reaches the uneven portion 157, and the amount of light emitted from the uneven portion 157 increases.

  In the pachinko machine 10 described above, on the back side of the main body frame 12, the main control device 271 that controls and manages the game, the sound lamp control device 272 that controls the speaker 20, the LED 154 for the light guide plate, etc., and the symbol display device 160 are controlled. The display control board 278, the payout control device 311 for controlling the payout of the game ball, the power supply and operation control device 313 for controlling the supply of operation power and the launch of the game ball, and the payout control device 311 are controlled so as to pay out the game ball. A payout mechanism 352 to be executed, a relay terminal plate 276, and various connection boards 314 and 381 are provided. Therefore, the electrical configuration of these pachinko machines 10 will be described below based on the block diagram of FIG. In FIG. 12, a power supply line is indicated by a double line arrow, and a signal line is indicated by a solid line arrow.

  A main control board 271a provided in the main control device 271 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic device. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. A RAM 503 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  Even after the power of the pachinko machine 10 is shut off, the RAM 503 is supplied with the data storage holding power (data storage holding voltage) from the power supply and the launch control board 313a provided in the launch control device 313 and holds the data. It is the composition which becomes. Specifically, the power and firing control board 313a is provided with a data storage holding capacitor, and the data storage holding power is supplied from the capacitor.

  An input / output port is connected to the CPU 501 of the main control board 271a via a bus line including an address bus and a data bus. Connected to the input side of the main control board 271a are a power supply monitoring board 271b provided in the main control apparatus 271, a payout control board 311a provided in the payout control apparatus 311 and other switch groups (not shown). In this case, a power supply and launch control board 313a is connected to the power supply monitoring board 271b, and power is supplied to the main control board 271a via the power supply monitoring board 271b.

  On the other hand, a power monitoring board 271b and a payout control board 311a are connected to the output side of the main control board 271a. Various commands such as a prize ball command are output to the payout control board 311a. In such a case, the various commands are output by one-way communication via the harness HL (that is, information indicating that the command has been input is not output from the payout control board 311a to the main control board 271a). A relay terminal plate 276 is connected to the output side of the main control board 271a. Various commands and the like are output from the main control board 271a to the voice lamp control board 272a provided in the voice lamp control device 272 via the relay terminal board 276. Furthermore, an LED lamp switch disposed in the first specific lamp unit 117 and an LED lamp switch disposed in the second specific lamp unit 118 are also connected. Thus, the first specific lamp unit 117 and the second specific lamp unit 118 are directly controlled by the main control board 271a.

  The power monitoring board 271b relays between the main control board 271a and the power and launch control board 313a, and monitors a DC stable 24 volt power that is the maximum power output from the power and launch control board 313a.

  The payout control board 311a performs payout control of prize balls and rental balls by a payout motor. The CPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the CPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

  Similarly to the RAM 503 of the main control board 271a, the RAM 513 of the payout control board 311a can hold data by supplying data storage holding power from the power supply and launch control board 313a even after the pachinko machine 10 is powered off. It has become. In addition, in the work area where various counters and the like in the RAM 513 are stored, a command buffer 513a for storing commands output from the main control board 271a is provided together with various flag storage areas such as a command input flag storage area. Yes.

  The command buffer 513a is a ring buffer that temporarily stores commands output from the main control board 271a. The ring buffer has a predetermined storage area, and commands are stored with regularity from the beginning to the end of the storage area. When commands are stored in all the storage areas, the ring buffer is The return command is configured to be updated. Therefore, when the command is stored and when the command is read, the storage pointer and the read pointer in the command buffer 513a are updated, and the command is stored and read based on each pointer.

  An input / output port is connected to the CPU 511 of the payout control board 311a via a bus line including an address bus and a data bus. On the input side of the payout control board 311a, a main control board 271a (via the above-described harness HL), a power source and launch control board 313a, and a payout mechanism unit connection board 381 are connected. The main control board 271a and the payout mechanism connection board 381 are connected to the output side of the payout control board 311a. In such a case, a payout mechanism portion 352 including a payout device 358 and the like is connected via a payout mechanism portion connection board 381.

  The power supply and launch control board 313a includes a power supply unit and a launch control unit. The power supply unit supplies necessary operation power to each of the main control board 271a, the payout control board 311a, and the like through a path indicated by a double line arrow. As its outline, the power supply unit takes in the AC 24 volt power supplied via the payout mechanism unit connection board 381, +12 V power for driving various switches, motors, etc., +5 V power for logic, RAM data A memory holding power source or the like is generated, and these + 12V power source, + 5V power source and data memory holding power source are supplied to the main control board 271a, the payout control board 311a and the like. Note that generating the data storage holding power supply means charging the data storage holding capacitor.

  The launch control unit is responsible for launch control of the launch solenoid 52 in accordance with the operation of the game ball launch handle 18 by the player, and the launch solenoid 52 is driven when a predetermined launch condition is satisfied. Specifically, a launch switch 331, a touch sensor 332, and a stop switch 333 provided on the game ball launch handle 18 are connected to the launch controller, and the launch switch 331 and the touch sensor 332 are turned on and the stop switch Only when 333 is turned off, the emission permission signal is output to the main control board 271a (via the power supply monitoring board 271b). The main control board 271a outputs a firing control signal of a predetermined cycle to the firing control unit (via the power monitoring board 271b) based on the input of the firing permission signal. Thereby, the firing control unit drives the firing solenoid 52 according to the input period of the firing control signal. In this case, the game ball launching handle 18 is provided with a dial variable resistor for determining the amount of handle operation, and the firing control unit launches by the firing solenoid 52 based on a change in resistance value in the dial variable resistor. Determine the speed.

  Note that a RAM erase switch circuit is provided in the power supply unit, which takes in a switch signal of the RAM erase switch and clears data stored in the RAM 503 of the main control board 271a according to the state of the switch 323. A RAM erase signal is output. That is, when the RAM erase switch is pressed, the RAM erase switch circuit outputs a RAM erase signal to the main control board 271a. Thereby, when the power of the pachinko machine 10 is turned on while the RAM erase switch is pressed, the data in the RAM 503 is cleared on the main control board 271a. At this time, a payout initialization command is output from the main control board 271a to the payout control board 311a, and the data in the RAM 513 is also cleared in the payout control board 311a.

  The sound lamp control board 272a controls the display control board 278 and the LED 154 for the light guide plate provided in the game board unit 100. The sound lamp control board 272a includes a CPU, a ROM, a RAM, and the like, and an input / output port is connected to the CPU via a bus line including an address bus and a data bus. The main control board 271a is connected to the input side of the sound lamp control board 272a through the relay terminal board 276 and connected to the display control board 278 and the light guide plate based on various commands output from the main control board 271a. The LED 154 is controlled. The display control board 278 controls the symbol display device 160 based on a display command input from the sound lamp control board 272a.

  Next, basic display contents in the symbol display device 160 will be described with reference to FIG.

  The symbol display device 160 is set with three symbol columns, left, middle, and right. Each symbol row is composed of, for example, a main symbol with numbers “0” to “9” and a sub-symbol made of, for example, a diamond-shaped picture. Each main symbol and sub-design constitute a first symbol. In each symbol row, main symbols are arranged in ascending or descending order of numbers, and sub symbols are arranged between the main symbols. That is, each symbol row is provided with a total of 20 first symbols of 10 main symbols and 10 sub symbols. In this case, the main symbols with odd numbers (1, 3, 5, 7, 9) correspond to “high probability symbols”, and when the high probability symbols are aligned, the big game state that is a special gaming state is entered. After that, the state shifts to a state with a high probability. The main symbols with even numbers (2, 4, 6, 8) correspond to “low-probability symbols”. When the low-probability symbols are aligned, the game shifts to a jackpot state. Does not transition to the time state. The high probability means a state where the combination of the first symbol is a big hit by a predetermined combination of probability fluctuation symbols and the subsequent big hit probability is increased as added value, that is, a so-called probable change. (When probability) means the time when it is not such a probable state. Further, in the first specific lamp unit 117, red is displayed at the big hit when the probability change state is reached, and green is displayed at the big hit at the normal state.

  On the symbol display device 160, 20 first symbols for each symbol row are variably displayed so as to scroll from top to bottom with periodicity. In particular, the numbers of the main symbols appear in descending order in the left symbol row, and the numbers of the main symbols appear in ascending order in the middle symbol row and the right symbol row. The symbol display device 160 displays the first symbol of the upper, middle, and lower levels for each symbol row. Therefore, the symbol display device 160 displays a total of nine first symbols of 3 rows × 3 columns. The symbol display device 160 has five effective lines, that is, an upper line L1, a middle line L2, a lower line L3, a right rising line L4, and a left rising line L5. Then, the variable display stops in the order of left symbol sequence → right symbol sequence → middle symbol sequence, and at the time of the stop, it is a combination of jackpot symbols on any active line (in this embodiment, the same main symbol combination) If you arrange it, a big hit video will be displayed as a big hit.

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

  In the present embodiment, the CPU 501 in the main control device 271 uses various counter information at the time of game to make a jackpot lottery, set the emission color of the first specific lamp unit 117, set the symbol display of the symbol display device 160, etc. Specifically, as shown in FIG. 14, the jackpot random number counter C1 used for the jackpot lottery, the jackpot type counter C2 used for determining the jackpot type, and the symbol display device 160 Reach random number counter C3 used for reach lottery when out-of-range changes, random number initial value counter CINI used for initial value setting of jackpot random number counter C1, and first variation type counter used for variation pattern selection of symbol display device 160 CS1 and the second variation type cow that determines the period for switching the color displayed on the first specific lamp unit 117 A motor CS2, is set to be used left column, the middle column and the right column the off each off symbol counters in the left-and right to use the setting symbol CL of, CM, and CR.

  Among these, the counters C1 to C3, CINI, CS1, and CS2 are loop counters that each add 1 to the previous value and return to 0 after reaching the maximum value. Further, the out symbol counters CL, CM, CR are configured such that register values are added using an R register (refresh register) in the CPU 501, and as a result, numerical values change randomly. Each counter is updated at short time intervals, and the updated value is appropriately stored in a counter buffer set in a predetermined area of the RAM 503. The RAM 503 is provided with a holding ball storage area composed of one execution area and four holding areas (holding first to fourth areas). In each of these areas, game balls to the operation port 115 are provided. The values of the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are stored in time series according to the winning history.

  For details of each counter, the jackpot random number counter C1 is configured such that, for example, 1 is sequentially added within a range of 0 to 676, and after reaching the maximum value (that is, 676), it returns to 0. In particular, when the jackpot random number counter C1 makes one round, the value of the random number initial value counter CINI at that time is read as the initial value of the jackpot random number counter C1. The random number initial value counter CINI is a loop counter similar to the jackpot random number counter C1 (value = 0 to 676), and is updated once for each timer interruption and is repeatedly updated within the remaining time of normal processing. The jackpot random number counter C1 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 115. The number of random number values that are jackpots is set at low probability and high probability, and the number of random numbers that are jackpots at low probability is 2, and the value is “337,673”. There are 10 random numbers that are big hits at high probability, and the values are “67, 131, 199, 269, 337, 401, 463, 523, 601, 661”.

  The jackpot type counter C2 is incremented by 1 within a range of 0 to 49, and reaches a maximum value (that is, 49) and then returns to 0. In the present embodiment, the jackpot type counter C2 determines whether the probability change state or the normal state is set after the jackpot is finished. For example, the jackpot that C2 = 0 to 24 becomes the probability change state. In this case, C2 = 25 to 49 corresponds to a jackpot that is in a normal state. The jackpot type counter C2 also determines the symbol combination when the symbol display device 160 stops changing and the position where the symbol combination is stopped. In other words, in the present embodiment, there are five effective lines in the symbol display device 160 and ten specific symbols (main symbols) are set, so that all patterns are set by 50 counter values. Will be. Then, when C2 = 0 to 24, that is, when the jackpot is in a probable variation state, the combination of the odd-numbered symbols and the position at which the symbol combination is stopped are determined. On the other hand, when C2 = 25 to 49, that is, when the jackpot is a normal state, the combination of the even-numbered symbols and the position at which the symbol combination is stopped are determined. The big hit type counter C2 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 115.

  For example, the reach random number counter C3 is incremented one by one within a range of 0 to 238, for example, and reaches a maximum value (that is, 238) and then returns to 0. In the present embodiment, the reach random number counter C3 causes the final stop symbol after the occurrence of reach to stop by shifting the last stop symbol by one before and after the reach symbol, and the final stop symbol after the occurrence of reach also reaches the reach symbol. “Reach other than front / rear off” that stops other than before and “completely out” that does not generate reach, for example, C3 = 0, 1 corresponds to front / rear reach, and C3 = 2-21 It corresponds to reach other than front / rear detachment, and C3 = 22 to 238 corresponds to complete detachment. Reach lottery may be individually set according to the state of the lottery probability of the symbol display device 160, the number of suspended balls at the start of change, and the like. The reach random number counter C3 is updated periodically (once every timer interruption in this embodiment), and stored in the reserved ball storage area of the RAM 503 at the timing when the game ball wins the operation port 115.

  The first variation type counter CS1 is, for example, incremented by 1 within a range of 0 to 198, and reaches a maximum value (that is, 198) and then returns to 0. The second variation type counter CS2 includes, for example, Within the range of 0 to 240, 1 is added in order, and after reaching the maximum value (that is, 240), it returns to 0. The first variation type counter CS1 determines the display mode of the symbol display device 160, such as the reach type of the first symbol such as so-called normal reach, super reach, premium reach, and other rough symbol variation modes. In this case, an enlarged display reach described later is included as a kind of super reach or premium reach. The switching display time as a period for switching the color displayed on the first specific lamp unit 117 is determined by the second variation type counter CS2. The switching display time corresponds to the symbol variation time of the symbol display device 160. Therefore, by the second variation type counter CS2, the elapsed time (in other words, the number of variation symbols) until the final stop symbol (in this embodiment, the middle symbol) stops after the reach is generated in the symbol display device 160, etc. A detailed design variation mode is also determined. That is, regarding the symbol display device 160, a variety of variation patterns can be easily realized by combining both the variation type counters CS1 and CS2. Both variation type counters CS1 and CS2 are updated once every time a normal process to be described later is executed once, and are repeatedly updated even within the remaining time in the normal process. Then, the buffer values of both variation type counters CS1 and CS2 are acquired when switching the color displayed on the first specific lamp unit 117 and determining the variation pattern at the beginning of variation of the first symbol by the symbol display device 160.

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

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

  In addition, the magnitude | size and range of each counter are only examples, and can be changed arbitrarily. However, if importance is attached to irregularity, it is desirable that the jackpot random number counter C1, the reach random number counter C3, and the variation type counters CS1 and CS2 are all different prime numbers and are not synchronized in any case. Although not shown, the second specific lamp random number counter C4 is used for the lottery of the second specific lamp unit 118. The second symbol random number counter C4 is configured, for example, as a loop counter that increments one by one within a range of 0 to 250 and returns to 0 after reaching the maximum value (that is, 250). The second specific ramp random number counter C4 is periodically updated (once every timer interruption in the present embodiment), and is acquired when it is detected that the game ball has passed through either the left or right through gate 116. The number of random number values to be won is 149, and the range is “5 to 153”.

  Next, each control process executed by the CPU 501 of the main control board 271a will be described with reference to the flowcharts of FIGS. The processing of the CPU 501 is broadly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and power failure to the NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by signal input. For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  The NMI interrupt process is executed when the power of the pachinko machine 10 is shut down due to the occurrence of a power failure or the like. That is, when the power of the pachinko machine 10 is cut off due to the occurrence of a power failure or the like, a power failure signal is output from the power monitoring board 271b to the NMI terminal of the CPU 501, and the CPU 501 interrupts the control being executed and starts NMI interrupt processing. . In the NMI interrupt processing, the power failure flag is set in the power failure flag storage area provided in the RAM 503, and this processing is terminated. Thereafter, when it is confirmed that the power failure flag is set in the normal processing described later, the power failure processing is executed. This process will be described later in detail.

  Next, timer interrupt processing executed by the CPU 501 of the main control board 271a, for example, every 2 msec will be described with reference to the flowchart of FIG.

  First, in step S101, signal reading processing from various winning switches, payout control board 311a, and the like is executed. That is, the state of various switches connected to the main control board 271a and the signal from the payout control board 311a are read, and the detection information is stored by determining the state of the switch and the signal (however, the RAM erase switch Excluding status and power failure signal). The detection information is saved by setting a flag in a flag storage area corresponding to each detection information set in the RAM 503.

  Thereafter, in step S102, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In the subsequent step S103, the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3 are updated. Specifically, the jackpot random number counter C1, the jackpot type counter C2 and the reach random number counter C3 are each incremented by 1 and their counter values reach the maximum values (in the present embodiment, 676, 49 and 238, respectively). Each time it is cleared to 0. Then, the updated values of the counters C1 to C3 are stored in the corresponding buffer area of the RAM 503.

  Thereafter, the start winning process is executed in step S104, and then this process is terminated. In the start winning process, it is determined based on the detection information of the operation port switch whether or not the game ball has won the operation port 115 (start prize). When it is determined that the game ball has won the operation opening 115, it is determined whether or not the number of operation hold balls of the first specific lamp unit 117 and the symbol display device 160 is less than the upper limit value (4 in the present embodiment). To do. On the condition that there is a winning at the operation port 115 and the number of operation holding balls is less than 4, the number of operation holding balls is incremented by 1, and the updated jackpot random number counter C1, jackpot type counter C2 and reach random number counter C3 Are stored in the first area of the free storage area of the reserved ball storage area of the RAM 503.

  In addition, when the game ball wins the operation opening 115 (start winning prize), the display of the first symbol on the symbol display device 160 is started accordingly, but after the winning winning, the first symbol changes and the symbol is changed. There is a restriction that a predetermined time (for example, 5 seconds) must elapse before stopping. Therefore, in the start winning process, when a start winning is confirmed, a timer for measuring the elapsed time after the start winning is set after each counter value storing process. Specifically, since the start winning process is executed at a cycle of 2 msec, for example, in order to measure an elapsed time of 5 seconds, a numerical value “2500” is set in the timer, and the timer value is incremented by 1 for each start winning process. Subtract. This timer value is stored and managed in the reserved ball storage area of the RAM 503 together with the values of the respective counters C1 to C3. Then, when setting the variation pattern of the first symbol, which will be described later, the timer value is referred to, and the variation pattern is set according to the remaining time (so that the symbol variation is stopped after a predetermined time has elapsed). .

  Next, the main process that is started upon reset at power-on will be described with reference to the flowchart of FIG.

  First, in step S201, an initial setting process associated with power-on is executed. Specifically, a wait process is executed, for example, for about 1 second in order to wait for the slave control board (such as the payout control board 311a) to become operable. In the subsequent step S202, access to the RAM 503 is permitted.

  Thereafter, in step S203, it is determined whether or not the RAM erase switch provided in the power supply and launch control device 313 is turned on. In subsequent step S204, it is determined whether or not the power failure flag is set in the power failure flag storage area of the RAM 503. Determine. In step S205, a RAM determination value is calculated. In subsequent step S206, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is a checksum value at a work area address of the RAM 503, for example. It is possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 503 are correctly stored.

  As described above, in the pachinko machine 10, when RAM data is initialized when the power is turned on, for example, at the start of business in the hall, the power is turned on while pressing the RAM erase switch. Therefore, if the RAM erase switch is pressed, the process proceeds to steps S209 to S211. Similarly, when the information on occurrence of power shut-off is not set, or when an abnormality of data stored and held by the RAM determination value (checksum value or the like) is confirmed, the process proceeds to steps S209 to S211.

  In step S209, in order to initialize the payout control board 311a (and the sound lamp control board 272a and the like) which is the slave control board, a payout initialization command (and a display initialization command and the like) is output. In subsequent step S210, the used area of the RAM 503 is cleared to 0, and in step S211, initialization processing of the RAM 503 is executed. Thereafter, interrupt permission is set in step S212, and the routine proceeds to normal processing to be described later.

  On the other hand, if the RAM erase switch has not been pressed, the power failure flag storage area is set in step S207 on the condition that the power failure flag is set and that the RAM judgment value (checksum value, etc.) is normal. Clear the power failure flag stored in. After that, in step S208, a power recovery command for returning the slave control board (such as the payout control board 311a and the sound lamp control board 272a) to the gaming state before the power-off is output. Thereafter, interrupt permission is set in step S212, and the routine proceeds to normal processing to be described later. Thereby, it returns to the state before power-off.

  Next, normal processing will be described using the flowchart of FIG. In this normal process, the main process of the game is executed. As its outline, the processing of steps S301 to S309 is executed as a periodic processing with a period of 4 msec, and the counter update processing of steps S310 and S311 is executed with the remaining time.

  In the normal process, in step S301, output data such as a command updated in the previous process is output to each control board on the slave side. Specifically, the command set in the command setting process described later is output to the sound lamp control board 272a and the payout control board 311a. In addition, a stop symbol command, a variation mode command, etc. are output to the sound lamp control board 272a (display control board 278) when the symbol display device 160 displays the fluctuation of the first symbol.

  Next, in step S302, update of both variation type counters CS1 and CS2 is executed. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503. In the subsequent step S303, updating of each off symbol counter CL, CM, CR of the left symbol row, the middle symbol row, and the right symbol row is executed.

  In the update process of the out symbol counters CL, CM, CR, it is determined whether or not it is the update timing of any of the left, middle, and right symbol sequences, and the out symbol counters CL, CM, CR of the symbol sequence that has reached the update timing are determined. Update. Each out symbol counter CL, CM, CR is updated one by one in one normal process without duplication, and every time the normal processing is executed three times, one set of out symbol counters CL, CM, CR is obtained. It has been updated. And, when the combination of the updated out symbol counters CL, CM, CR is a combination of outreach symbols that are front / rear out of reach, a combination of reach symbols other than front / rear out of reach, a combination of completely out symbols that do not become reach In some cases, the combination is stored in a corresponding buffer. If the combination of the updated off symbol counters CL, CM, and CR is a combination of jackpot symbols, the update process is terminated as it is.

  After the process of updating the off symbol counters CL, CM, CR, command setting processing is executed in step S304. In this command setting process, a prize ball command and an error command are set. That is, when a game ball has won a prize in any of the general prize opening 113, the variable prize winning device 114, or the operation slot 115, a prize ball command corresponding to the winning place is set, and there is an abnormality in the payout mechanism unit 352. If an abnormal signal is input from the payout control board 311a due to the occurrence, an error command is set. The set prize ball command is output to the payout control board 311a in the external output process described above, whereby the prize ball is paid out. Further, the set error command is output to the sound lamp control board 272a by the above-described external output process, so that the error display lamp 37 is controlled to blink in a predetermined manner.

  After the command setting process, a first specific lamp unit control process for switching the color displayed on the first specific lamp unit 117 is executed in step S305. In the first specific lamp unit control process, jackpot determination, on / off control of a light source switch of an LED lamp disposed in the first specific lamp unit 117, and the like are performed. In the first specific lamp unit control process, the symbol display device 160 also sets the first symbol variation display.

  Specifically, it is determined whether or not the jackpot is based on the value of the jackpot random number counter C1, and further determines the type of jackpot based on the value of the jackpot type counter C2 (determines whether or not it is a so-called probabilistic jackpot). . At this time, the type of jackpot symbol in the first symbol and the stop line for the combination of jackpot symbols are also determined and set as a stop symbol command. If it is determined that no jackpot will occur, the combination of outlier symbols in the first symbol is determined based on the value of the reach random number counter C3. In such a case, the combination of symbols updated in the outlier symbol counter updating process and stored in the buffer is set as a stop symbol command. Further, based on the value of the second variation type counter CS2, the color switching display time displayed on the first specific lamp unit 117 and the variation display time of the first symbol are determined. Further, the reach type in the first symbol and its rough symbol variation mode are determined based on the value of the first variation type counter CS1, and set as a variation mode command. Each time the on / off control of the first specific lamp unit 117 is started in the first specific lamp unit control process, the number N of the operation-reserved balls is decremented by 1 and when the operation-reserved ball number N is 0, the on / off control is performed. Does not start.

  After the first specific lamp unit control process, a special winning opening opening / closing process is executed in step S306. In the big prize opening / closing process, the big prize opening of the variable prize winning device 114 is opened or closed in the case of a big hit state. That is, it is determined whether the big winning opening is opened for each round of the big hit state, and whether the maximum opening time of the big winning opening has passed or whether a predetermined number of game balls have been won in the big winning opening. When either of these conditions is satisfied, the special winning opening is closed. At this time, the continuous winning opening is allowed on condition that the game ball has passed the specific area, and this is repeatedly executed for a predetermined number of rounds.

  Thereafter, in step S307, a second specific lamp unit control process for switching the color displayed on the second specific lamp unit 118 is executed. Briefly, on the condition that the game ball has passed through the through gate 116, the value of the second specific lamp random number counter C4 is acquired and the color switching process displayed on the second specific lamp unit 118 is acquired each time. Is implemented. Then, when the lottery of the color displayed by the value of the second specific lamp random number counter C4 is performed and the red color is selected, the electric accessory attached to the operation port 115 is opened for a predetermined time. Although the description is omitted, the second specific ramp random number counter C4 is also updated by the timer interrupt process shown in FIG. 15, similarly to the big hit random number counter C1, the big hit type counter C2, and the reach random number counter C3. .

  After step S307, a game ball launch control process is executed in step S308. In the game ball launch control process, on the condition that a launch permission signal is input from the power source and launch control board 313a, the launch control signal is output to the power source and launch control board 313a at a cycle of 0.6 seconds. The power supply and launch control board 313a excites the launch solenoid 52 once every time a launch control signal is input. That is, when a player operates the game ball launch handle 18 under a situation where sufficient game balls are stored in the upper plate 23, 100 game balls are launched per minute.

  After the game ball launch control process, in step S309, it is determined whether or not a power failure flag is set in a power failure flag storage area provided in the RAM 503. When the power failure flag is not set, the last process of the plurality of processes that are repeatedly executed is completed, so whether or not the execution timing of the next normal process is reached in step S310, that is, the previous normal process It is determined whether or not a predetermined time (4 msec in this embodiment) has elapsed since the start of the process. Then, the random number initial value counter CINI and both variation type counters CS1 and CS2 are repeatedly updated within the remaining time until the next normal processing execution timing (steps S311 and S312). That is, in step S311, the random number initial value counter CINI is updated. Specifically, the random number initial value counter CINI is incremented by 1 and cleared to 0 when the counter value reaches the maximum value (676 in this embodiment). Then, the update value of the random number initial value counter CINI is stored in the corresponding buffer area of the RAM 503. In step S312, updating of both variation type counters CS1 and CS2 is executed. Specifically, both variation type counters CS1 and CS2 are incremented by 1, and are cleared to 0 when their counter values reach the maximum values (198 and 240 in this embodiment). Then, the update values of both variation type counters CS 1 and CS 2 are stored in the corresponding buffer area of the RAM 503.

  Here, since the execution time of each process of steps S301 to S309 changes according to the state of the game, the remaining time until the next normal process execution timing is not constant and varies. Therefore, by repeatedly updating the random number initial value counter CINI using the remaining time, the random number initial value counter CINI (that is, the initial value of the big hit random number counter C1) can be updated at random. Similarly, Both variation type counters CS1 and CS2 can be updated at random.

  On the other hand, if it is determined in step S309 that the power failure flag is set, the power supply is shut off due to the power failure, so the power failure processing from step S313 is executed. That is, in step S313, the generation of each interrupt process is prohibited, and then, in step S314, a power failure command indicating that the power has been cut off is sent to another control board (such as the payout control board 311a and the voice lamp control board 272a). Output. In step S315, the RAM determination value is calculated and stored, and after the access to the RAM 503 is prohibited in step S316, the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power supply is completely shut down, the data storage holding power of the RAM is supplied from the power supply and the launch control board 313a. Therefore, the information stored in the RAM 503 before the power shuts down as it is. It is held within a period (for example, 1 day or 2 days).

  Next, each control process executed by the CPU 511 of the payout control board 311a will be described with reference to the flowcharts of FIGS. The processing of the CPU 511 is roughly divided into main processing that is started when the power is turned on, timer interrupt processing that is started periodically (in this embodiment, at a cycle of 2 msec), and commands that are output from the main control board 271a. For convenience of explanation, the input interrupt process will be described first, and then the main process and timer interrupt process will be described.

  In the interrupt process at the time of input, the command output from the main control board 271a is stored in the command buffer 513a of the RAM 513, and a command input flag is set in a command input flag storage area provided in the RAM 513. As described above, when a command is stored in the command buffer 513a, the storage pointer is referred to and stored in a predetermined storage area, and the next input command is stored to be stored in the next storage area. The pointer is updated.

  Next, the main process of the payout control board 311a will be described with reference to the flowchart of FIG. This main process is started upon reset at power-on.

  First, in step S401, an initial setting process associated with power-on is executed. Specifically, the interrupt mode is set. In step S402, RAM access is permitted, and in step S403, an external interrupt vector is set.

  Thereafter, in step S404, it is determined whether or not a power failure flag is set in the power failure flag storage area of the RAM 513. In step S405, a RAM determination value is calculated. In subsequent step S406, it is determined whether or not the RAM determination value matches the RAM determination value stored when the power is turned off, that is, the validity of the stored data. The RAM determination value is, for example, a checksum value at a work area address in the RAM 513. It is also possible to determine the validity of the stored data based on whether or not the keywords written in a predetermined area of the RAM 513 are correctly stored.

  When the power failure flag is not set, or when an abnormality of data stored and held is confirmed by the RAM determination value (checksum value or the like), the process proceeds to initialization processing (steps S411 to S413) of the RAM 513. That is, in step S411, the entire area of the RAM 513 is cleared to 0, and in the subsequent step S412, initialization processing of the RAM 513 is executed. In step S413, the CPU peripheral device is initialized.

  On the other hand, when the power failure flag is set and the RAM determination value (checksum value or the like) is normal, processing at power recovery (processing at recovery after power interruption due to power failure) is executed. That is, in step S407, the power failure flag is cleared, and in step S408, the payout permission flag for permitting the payout of prize balls is cleared. In step S409, the CPU peripheral device is initialized. The RAM determination value is, for example, a checksum value at the work area address of the RAM 513.

  After the process of step S409 or step S413, the interruption is permitted in step S410, and it is determined whether or not the power failure flag is set in the power failure flag storage area of the RAM 513 in step S414, and the power failure flag is set. If not, wait until the power failure flag is set.

  On the other hand, if the power failure flag is set, it means that a power failure has occurred, and therefore the process of step S415 is executed as a power failure process. In the power failure process, first, in step S415, the generation of each interrupt process is prohibited. Thereafter, the RAM determination value is calculated and stored in step S416, and access to the RAM 513 is prohibited in step S417, and the infinite loop is continued until the power supply is completely shut down and the process cannot be executed. Even after the power is completely shut off, the data stored in the RAM 513 is supplied from the power and launch control board 313a, so that the information stored in the RAM 513 before the power is shut off is within a predetermined period (for example, 1 or 2 days).

  Next, timer interrupt processing executed by the CPU 511 of the payout control board 311a, for example, every 2 msec will be described with reference to the flowchart of FIG.

  First, in step S501, command determination processing for determining a command input from the main control board 271a is executed. In this command determination process, as shown in FIG. 20, it is determined whether or not a command input flag is set in the command input flag storage area of the RAM 513 in step S601. If the command input flag is not set, a new command has not been output from the main control board 271a, so this process is terminated. On the other hand, if the command input flag is set, command read processing is executed in step S602. In the command read process, the input command is read from the command buffer 513a of the RAM 513, and the command input flag is cleared.

  Thereafter, the type of the read command is determined in each process of step S603, step S605, step S610, and step S611, and a process corresponding to each command is executed. That is, in step S603, it is determined whether or not the command is a power failure command. If the command is the command, the power failure flag is set in the power failure flag storage area of the RAM 513 in step S604, and the process is terminated. When this power failure flag is set, the power failure process described above is executed.

  In step S605, it is determined whether the command is a payout initialization command. If the command is the command, initialization of the RAM 513 is instructed from the main control board 271a when the power is turned on. After executing the process of step S609, the present process is terminated. In step S606, it is determined whether or not a payout permission flag is set in a payout permission flag storage area provided in the RAM 513. If the flag is not set, the work area of the RAM 513 is set to 0 in step S607. Then, the initial value of the RAM 513 is set in step S608. Thereafter, in step S609, a payout permission flag is set to permit the payout of the winning ball.

  If the payout permission flag is set in step S606, the process ends without performing the processes in steps S607 and S608. With this configuration, even if the input of the payout initialization command is recognized due to noise or the like even though the RAM erasure switch is not pressed, the remaining prize balls are paid out to the player. Can be prevented without being erased.

  In step S610, it is determined whether or not the command is a power recovery command. If the command is the command, the payout control board 311a returns to the state before the power cut-off due to a power failure, so the payout permission flag is set in step S609. After setting, this process is terminated. With such a configuration, when a prize ball remains before the power is turned off, the prize ball can be paid out immediately.

  In step S611, it is determined whether or not the command is a prize ball command. If the command is the command, the number of prize balls corresponding to the prize ball command is added to the total number of prize balls in step S612, and then in step S609. The payout permission flag is set and the process is terminated.

  If the command read from the command buffer 513a is not a power failure command, a payout initialization command, a power recovery command, or a prize ball command, the command is recognized as a command caused by noise or the like, and the command buffer 513a This process is ended without performing other processes only by updating the read pointer.

  Returning to the description of the timer interrupt process (FIG. 19), after executing the command determination process, it is determined whether or not the payout permission flag is set in step S502. If the payout permission flag is not set, the process is terminated. On the other hand, if the payout permission flag is set, the state return switch is checked in step S503, and the state return operation is executed when it is determined that the state return operation starts.

  In step S504, setting of a tank ball absence state or a tank ball absence release state is executed according to a change in the state of the tank ball. In other words, the tank ball no switch state is determined based on the detection signal of the tank ball no switch, and when there is no tank ball, the setting of the tank ball no state is executed. Perform configuration. In such a case, an abnormal signal is output to the main control board 271a when setting the tank ball absence state.

  Thereafter, in step S505, the presence / absence of the state to be notified is determined. If there is a state to be notified, the 7-segment LED provided in the payout control device 311 is notified.

  In steps S506 to S508, prize ball payout processing is executed. In this case, if the prize ball is not paid out and the total number of prize balls stored in the command determination process in step S501 is not 0 (both NO in steps S506 and S507), the process proceeds to step S508 and the prize ball control process is performed. To start. In other words, the payout device of the payout mechanism 352 is driven to pay out the prize balls. If the prize ball is not paid out or the total number of prize balls is 0 (YES in any of steps S506 and S507), the process proceeds to the rental payout process in steps S509 to S511.

  In the lending payout process, if the lending is not disabled and a lending payout request is received from the CR unit (NO in step S509, YES in S510), the process proceeds to step S511, and the lending control process To start. That is, the payout device of the payout mechanism unit 352 is driven and controlled to pay out the rental balls. Further, if a rental ball cannot be paid out or a rental ball payout request is not received (YES in step S509 or NO in S510), a subsequent ball removal process is executed.

  In step S512, the state return switch is checked to execute the ball removal process by driving the payout motor on the condition that the ball removal disabled state is not set and the ball removal operation is not started. In the subsequent step S513, vibrator control (vibrating motor control) is executed on condition that the ball is clogged. Thereafter, this process is terminated.

  Next, a display mode switching process executed by the CPU of the display control board 278 at a predetermined cycle (for example, 2 msec) will be described with reference to FIG. Here, the display mode switching process will be briefly described. In the present embodiment, the display screen 161 having a larger area than the game area 103 is provided. Reach production is performed. In such a configuration, when the variable display of symbols is performed, it is basically performed on a part of the display screen 161 (hereinafter also referred to as reduced display). In this case, a predetermined background image or the like is displayed in an area other than the area displayed in a reduced size on the display screen 161. On the other hand, when performing a predetermined reach effect or displaying a jackpot video in the jackpot state, the display is performed at least in an area wider than the game area 103 (hereinafter also referred to as an enlarged display). Then, the display area is switched between the reduced display and the enlarged display in the display mode switching process.

  In step S701, it is determined whether or not enlarged display is performed on the display screen 161 of the symbol display device 160. If the enlarged display is not performed, it is determined in step S702 whether or not the enlarged display start timing has come. Such a determination is made with reference to a timer value provided on the display control board 278. Specifically, the display control board 278 controls the symbol display device 160 based on the display command input from the sound lamp control board 272a. If the input display command includes information indicating that the enlarged display reach is to be performed, a predetermined value for start determination is set in the timer. This value corresponds to the time from the start of variable display of symbols to the start of enlarged display reach. Each time a negative determination is made in step S701, 1 is subtracted from the set value. When the value becomes 0, an affirmative determination is made in step S702. When the timer value is 0, such subtraction is not performed.

  If an affirmative determination is made in step S702, the display mode on the display screen 161 is switched from reduced display to enlarged display in step S703. If a negative determination is made, this processing is terminated as it is, and the display mode on the display screen 161 is continuously reduced.

  On the other hand, if it is determined in step S701 that the enlarged display is being performed, it is determined in step S704 whether the enlarged display end timing has come. Such determination is performed with reference to the timer value. Specifically, a predetermined value for determining termination is set in the timer at the timing when enlarged display is started as described above. This value corresponds to the time from the start to the end of the enlarged display reach. Further, when the gaming state shifts to the jackpot state, it corresponds to the time until the jackpot state ends. Each time an affirmative determination is made in step S701, 1 is subtracted from the set value. When the value becomes 0, an affirmative determination is made in step S704.

  If an affirmative determination is made in step S704, the display mode on the display screen 161 is switched from enlarged display to reduced display in step S705. If a negative determination is made, this process is terminated as it is, and the display mode on the display screen 161 continues to be enlarged.

  Next, the light guide plate LED control process executed by the CPU of the sound lamp control board 272a at a predetermined cycle (for example, 2 msec) will be described with reference to FIG. Here, the LED control process for the light guide plate will be briefly described. In the present embodiment, the reduced display and the enlarged display are performed on the display screen 161 of the symbol display device 160 as described above. In this case, the division line of the area where the reduced display is performed on the display screen 161 by the light irradiated forward from the light guide plate 150 of the game board unit 100 is configured. As a result, it is possible to clearly teach the reduced display area. On the other hand, when the enlarged display is performed, it is necessary to stop the light irradiation from the light guide plate 150 and turn off the dividing line. Therefore, on / off control of the light guide plate LED 154 according to the display mode of the display screen 161 is performed in the light guide plate LED control processing. The light guide plate LED control process is performed substantially in synchronization with the display mode switching process on the display control board 278.

  In step S801, it is determined whether or not the enlarged display is performed on the display screen 161 of the symbol display device 160. If the enlarged display is not performed, it is determined in step S802 whether or not the enlarged display start timing has come. Such a determination is made with reference to a timer value provided on the sound lamp control board 272a. Specifically, the sound lamp control board 272a controls the light guide plate LED 154 based on the display command input from the main control board 271a. When the input display command includes information indicating that the enlarged display is performed on the display screen 161, a predetermined value is set in the timer. This value corresponds to the time from the start of variable display of symbols on the display screen 161 to the start of enlarged display. That is, this value is the same value as the predetermined value for determining the start of the timer on the display control board 278. Each time a negative determination is made in step S801, 1 is subtracted from the set value. When the value becomes 0, an affirmative determination is made in step S802. When the timer value is 0, such subtraction is not performed.

  If an affirmative determination is made in step S802, the control of the light guide plate LED 154 is switched from on control to off control in step S803. As a result, the introduction of light into the light guide plate 150 is stopped and the lane marking disappears. If a negative determination is made, the process is terminated as it is, and the introduction of light into the light guide plate 150 is continued. Thereby, the state where the lane markings are represented is continued.

  On the other hand, if it is determined in step S801 that enlarged display is being performed, it is determined in step S804 whether or not the enlarged display end timing has come. Such determination is performed with reference to the timer value. Specifically, a predetermined value for determining the end is set in the timer at the timing when the OFF control of the LED 154 for the light guide plate is started as described above. This value corresponds to the time from when the enlarged display reach is started on the display screen 161 to the end thereof. Further, when the gaming state shifts to the jackpot state, it corresponds to the time until the jackpot state ends. That is, this value is the same value as the predetermined value for determining the end of the timer on the display control board 278. Each time an affirmative determination is made in step S801, 1 is subtracted from the set value. When the value becomes 0, an affirmative determination is made in step S804.

  If an affirmative determination is made in step S804, the control of the light guide plate LED 154 is switched from off control to on control in step S805. Thereby, the introduction of light into the light guide plate 150 is resumed, and a lane marking appears. If a negative determination is made, the present process is terminated as it is, and the state where the introduction of light into the light guide plate 150 is stopped is continued. Thereby, the state where the lane markings disappeared is continued.

  Next, a display mode visually recognized through the game area 103 will be described with reference to FIG. FIG. 23A shows a state where the image is displayed in a reduced size, and FIG. 23B shows a state where the image is displayed in an enlarged manner.

  In FIG. 23A, the variable display of symbols is performed in a reduced display on the display screen 161 in the symbol display device 160. Such reduced display is performed inside the frame-shaped center frame 130. In this case, since light is introduced from the light guide plate LED 154 to the light guide plate 150 of the game board unit 100, the partition line DL is represented by colored light on the outer edge of the reduced display. Note that a uniform background image is displayed outside the area of the display screen 161 that is displayed in a reduced size.

  In FIG. 23B, the reach effect is performed on the display screen 161 in an enlarged display. Such enlarged display is performed so as to be displayed in a large area in the gaming area 103 which is wider than the area where the division line DL is displayed. In this case, the introduction of light from the light guide plate LED 154 to the light guide plate 150 of the game board unit 100 is stopped, and the partition line DL disappears.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  A game display board 160 is provided on the back side of the game board unit 100, and the game area forming plate constituting the unit 100 is configured so that the display contents on the display screen 161 of the game display unit 160 can be visually recognized through the game board unit 100. 110 and the light guide plate 150 are formed of a transparent material. Thereby, the display screen 161 can be expanded as compared with the conventional pachinko machine 10, and a dynamic reach effect can be performed on the display screen 161.

  In this case, the display mode on the display screen 161 is switched from the reduced display to the enlarged display at a specific timing in the variable display of symbols. In other words, the normal symbol variable display is reduced and the enlarged display is performed when a specific reach effect is performed. Thereby, in the structure which expanded the display screen 161, the display mode can be made favorable. For example, if it is configured to always perform an enlarged display, it is necessary for the player to always visually recognize the entire game area 103, and the visibility may be deteriorated. Further, when the specific reach effect is performed, the enlarged display is performed, so that the specific reach effect is emphasized and the player's attention can be increased.

  Further, a light guide plate 150 is provided on the back side of the game area forming plate 110 as the game board unit 100, and the light guide plate 150 has a concavo-convex portion as a light emission area that forms a frame so as to partition an area where reduced display is performed. 157 was formed. As a result, the light emitted from the LED 154 for the light guide plate and introduced into the light guide plate 150 reaches the concavo-convex portion 157, and part of the light is transmitted through the light guide plate 150 and emitted toward the game area forming plate 110 side. . As a result, the division line DL is displayed so as to divide the area that is reduced and displayed, and the area can be clearly taught. In particular, in the present configuration, the partition line DL is not represented on the display screen 161 but is represented by the light emitted from the light guide plate 150, so that the effect taught above may be more remarkable. it can. This is because the visibility of the player is different between the pattern displayed on the display screen 161 and the light emitted from the light guide plate 150.

  When the display mode on the display screen 161 is switched from the reduced display to the enlarged display, the light guide plate LED 154 is switched from the on state to the off state. As a result, the division line DL disappears while the enlarged display is performed, and the enlarged display is not disturbed by the division line DL in the configuration in which the reduced display area is clearly taught as described above. .

  In addition, since the game area 103 is formed on the game area forming plate 110 instead of forming the game area 103 on the light guide plate 150, the above effects can be suitably achieved. That is, in the configuration in which the game area 103 is formed on the light guide plate 150, the nail 120 needs to be disposed on the front surface of the light guide plate 150. In this case, light may leak out from the position where the nail 120 is disposed, and the amount of light reaching the uneven portion 157 may be reduced. On the other hand, by forming the game area 103 on the game area forming plate 110 as described above, such inconvenience does not occur.

  Note that the light emission region is formed by the uneven portion 157. Thereby, the light emission region can be formed relatively easily and at a relatively low cost. In addition, the uneven portion 157 is mechanically formed. Thereby, formation of a light emission area | region can be performed more easily.

  The center frame 130 is formed in a frame shape so as to divide an area on the display screen 161 where the reduced display is performed. As a result, in a situation where the reduced display is performed, since the symbols are variably displayed within the area partitioned by the center frame, the display mode in the conventional pachinko machine is reproduced. In other words, a conventional pachinko machine generally has a configuration in which a symbol display device is installed in the approximate center of the game board, and a center frame is installed so as to surround the symbol display device. In this case, by performing the reduced display within the area partitioned by the center frame 130 as described above, the reduced display can be visually recognized without a sense of incongruity for a player accustomed to a conventional pachinko machine. On the other hand, in the enlarged display, symbols and the like are displayed beyond the area partitioned by the center frame 130. Therefore, the enlarged display can be emphasized more.

  Further, the uneven portion 157 was formed along the center frame 130. As a result, the division line DL is represented along the center frame 130, and in the configuration in which the center frame 130 is formed of a transparent material, the reduced display displayed in the area partitioned by the center frame 130 is clearly taught. can do.

  Further, the partition line DL is represented by the light emitted from the light guide plate 150 (uneven portion 157) on the back side of the game area forming plate 110, so that the distance in the front-rear direction is close to the center frame 130. A lane marking DL is represented. Therefore, the dividing line DL can be expressed along the center frame 130. In particular, in this configuration, the game board unit 100 and the symbol display device 160 are separated from each other in the front-rear direction, and the discharge passage unit 170 is disposed using the separated space. Further, the stage frame 140 of the center frame 130, the variable winning device 114, and the like are disposed so as to protrude to the back side of the game board unit 100 by using this separated space. In this case, if an attempt is made to display the lane marking DL on the display screen 161, it is difficult to display the lane marking DL along the center frame 130. A player who plays a game on the pachinko machine 10 has various positions of eyes with respect to the game area 103, and if the center frame 130 and the lane marking DL are separated from each other in the front and rear, they do not match depending on the viewing angle. It is. On the other hand, as described above, the partition line DL is represented by the light emitted from the light guide plate 150 on the back side of the game area forming plate 110, so that the above-described disadvantage does not occur.

  The uneven portion 157 was formed on the surface of the light guide plate 150 facing the game area forming plate 110. Thereby, the lane marking DL can be represented at a position where the distance in the front-rear direction is close to the center frame 130. For example, in the configuration in which the concavo-convex portion 157 is formed on the surface opposite to the surface facing the game area forming plate 110, the partition line DL and the center frame 130 are separated at least by the thickness of the light guide plate 150. is there.

  Further, the light guide plate 150 is disposed so as to overlap the game area forming plate 110 on the back side of the game area forming plate 110. Thereby, the lane marking DL can be represented at a position where the distance in the front-rear direction is close to the center frame 130. For example, in the configuration in which the game area forming plate 110 and the light guide plate 150 are largely separated, the partition line DL and the center frame 130 are separated from each other. Further, according to this configuration, the thickness dimension of the game board unit 100 can be made as small as possible, and the space required for providing the game board unit 100 can be reduced.

  An element substrate 155 provided with a light guide plate LED 154 as a light emitter is provided on the upper peripheral surface of the light guide plate 150. As a result, in the configuration in which the general winning opening 113 and the variable winning device 114 are provided near the lower end of the gaming area 103, the light introduced into the light guide plate 150 is not obstructed by the through holes 152a to 152i. It can reach the uneven portion 157, and light emission from the uneven portion 157 can be made favorable.

  A light reflecting tape 158 was provided so as to cover the peripheral wall portions of the through holes 152a to 152i. As a result, the light reaching the peripheral wall portions of the through holes 152 a to 152 i is reflected by the light reflecting tape 158 and travels through the light guide plate 150. Therefore, in the configuration in which the through holes 152a to 152i are provided in the light guide plate 150, it is possible to suppress the amount of light reaching the uneven portion 157 from decreasing. In addition, in a configuration in which the peripheral wall portions of the through holes 152a to 152i are not covered with the light reflecting tape 158, the light that totally reflects inside the light guide plate 150 is irradiated to the game balls that pass through the through holes 152a to 152i, and the game balls It is conceivable that the reflected light on the surface is visually confused with the light emitted through the concavo-convex portion 157. In this case, there is a possibility that inconveniences such as blurring of the division line DL or deterioration of the visibility of the symbol displayed in a reduced size may occur. On the other hand, since the peripheral wall portions of the through holes 152a to 152i are covered with the light reflecting tape 158, the occurrence of the inconveniences as described above can be suppressed.

  A light reflecting tape 159 is provided so as to cover a region excluding a portion where the element substrate 155 is provided on the peripheral surface of the light guide plate 150. As a result, the light reaching the peripheral surface of the light guide plate 150 is reflected by the light reflecting tape 159 and travels through the light guide plate 150. Therefore, the light reaching the peripheral surface of the light guide plate 150 is prevented from leaking from the light guide plate 150, and the amount of light reaching the uneven portion 157 can be suppressed from decreasing.

  The thickness dimension of the light guide plate 150 is reduced with respect to the game area forming plate 110 on which the nail is disposed. Thereby, the thickness dimension of the game board unit 100 can be made as small as possible, and the space required for providing the game board unit 100 can be reduced.

  The game area forming plate 110 and the light guide plate 150 are fixed on the outer peripheral side thereof. Thereby, the game board unit 100 can be provided suitably. For example, in a configuration in which an adhesive is applied and fixed to the opposing surfaces of the game area forming plate 110 and the light guide plate 150, bubbles and the like may be generated inside, which may increase the defect rate. .

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

  (1) The display mode of the lane markings DL in the game board unit 100 may be different from the above embodiment. An example of the change will be described with reference to FIGS. In the following description, only parts different from the above embodiment will be described.

  In FIG. 24, the partition line DL is not represented along the inner peripheral edge of the center frame 130 as in the above embodiment, but the partition line DL is represented so as to include the entire center frame 130. Yes. Also in this configuration, the region partitioned by the center frame 130 can be clearly taught by the partition line DL. Further, in this configuration, the game balls rolling on the ball passages 132 and 143 and the stage 144 of the center frame 130 are illuminated by the light from the light guide plate 150, and the visibility can be improved. Furthermore, the decorative effect can be enhanced.

  In FIG. 25, a plurality of (here, four) partition lines DL1 to DL4 are shown. Thereby, the mode of reduction display can be diversified. As such a mode, a mode in which reduced display is simultaneously performed in a region partitioned by the partition lines DL1 to DL4 can be considered. In this case, it is good also as a structure which transfers to a jackpot state, when the same symbol is prepared in all the areas. Moreover, it is good also as a structure by which reduction display is sequentially performed in the area | region divided by each division line DL1-DL4. In this case, a reduced display may be performed in the order of DL1, DL2, DL3, and DL4, and the degree of expectation for occurrence of a big hit state may be increased as the reduced display is developed in a later order. However, in order to sequentially reduce the display in this way, it is necessary to provide a combination of a light guide plate and a light emitter corresponding to each partition line DL1 to DL4.

  (2) The light guide plate 150 may not have the same shape and size as the game area forming plate 110. For example, a light guide plate smaller than the game area forming plate 110 may be provided. However, it is set to a size that can include a reduced display area. Even in such a configuration, it is possible to clearly teach the area to be reduced and displayed by forming the light emission area on the light guide plate.

  (3) The center frame 130 may be omitted. Even in such a configuration, the area to be reduced can be clearly taught by dividing the area by the division line DL.

  (4) In the above-described embodiment, the symbol display device 160 is attached to the resin base 25, but the configuration of such attachment is not limited to this. For example, in a configuration in which a rear cover member to which the main controller 271 and the like are attached is provided on the back side of the main body frame 12, a configuration in which the symbol display device 160 is attached to the rear cover member may be employed. Moreover, it is good also as a structure which provides the attachment frame for attaching the symbol display apparatus 160 in the back | inner side of the game board unit 100. FIG.

  (5) In the above embodiment, the game area forming plate 110 and the light guide plate 150 are provided so as to overlap each other, but they may be provided apart from each other. However, since it is not preferable that the center frame 130 and the dividing line DL are separated greatly, it is preferable that the game area forming plate 110 and the light guide plate 150 are provided close to each other.

  (6) The material for forming the game area forming plate 110 is not limited to polycarbonate resin, and any material can be used as long as it has transparency. For example, the game area forming plate 110 may be formed of an acrylic resin having better light transmission than polycarbonate resin. However, since the acrylic resin is generally less elastic than the polycarbonate resin, the game area forming plate 110 may be damaged by the impact when the game ball repeatedly hits the nail 120 or the like disposed. Further, even if the angle adjustment of the nail 120 is repeatedly performed, there is a possibility that the game area forming plate 110 may be damaged due to distortion generated at that time. Therefore, in a structure formed of acrylic resin, it is preferable to add a predetermined amount of synthetic rubber such as butadiene to the acrylic resin. Further, the addition amount of the synthetic rubber is more preferably 20 to 30%. In this case, the elasticity can be increased while suppressing the light transmittance from being extremely lowered.

  (7) The material forming the light guide plate 150 is not limited to acrylic resin, and any material having transparency can be used. Therefore, the light guide plate 150 may be formed of polycarbonate resin. However, it is preferable that the light guide plate 150 is formed of an acrylic resin in order to improve light transmission.

  (8) In the above embodiment, the uneven portion 157 as the light emission region is formed on the front surface of the light guide plate 150. Instead, the uneven portion 157 may be formed on the back surface of the light guide plate 150. In this case, the edge of the partition line DL can be made sharper than in the above embodiment. Further, the uneven portion 157 may be formed on the front surface and the back surface of the light guide plate 150.

  (9) It is good also as a structure which provides other than LED as a light-emitting body. For example, it is good also as a structure which provides a fluorescent tube. In this case, by making the length of the fluorescent tube approximately the same as the length of the upper peripheral surface of the light guide plate 150, light can be introduced into the light guide plate 150 from the entire one peripheral surface.

  (10) Although the light emitter is provided only on the upper peripheral surface of the light guide plate 150 in the above embodiment, this may be changed. For example, it is good also as a structure which provides a light-emitting body in the left or right end surface. Moreover, it is good also as a structure which provides a light-emitting body in the surrounding surface of all directions.

  (11) You may use LED of a multicolor light emission type as LED154 for light-guide plates. In this case, the color of the lane marking DL can be changed, and an effect based on the color of the light can be performed on the lane marking DL.

  (12) In the above embodiment, the openings 111 and 151 are formed at the four corners of the game area forming plate 110 and the light guide plate 150, respectively, and the screw 112 is inserted and fixed to each of the connected openings 111 and 151. However, this may be changed. For example, it is good also as a structure which provides and fixes a game area formation board 110 and the light-guide plate 150 so that it may be clamped forward and backward.

  (13) In the above embodiment, the light reflecting tapes 158 and 159 are provided as light reflecting means on the peripheral wall portions of the through holes 152a to 152i formed in the light guide plate 150 and the peripheral surface of the light guide plate 150. This may be changed. For example, a metal-added paste such as a silver paste may be applied instead of the light reflecting tapes 158 and 159.

  (14) In the above embodiment, the thickness dimension of the light guide plate 150 is made smaller than that of the game area forming plate 110. However, the present invention is not limited to this, and the thickness dimension of the light guide plate 150 is the same as that of the game area forming plate 110. The game area forming plate 110 may be larger.

  (15) The formation method of the concavo-convex portion 157 is not limited to the mechanical etching method, and for example, the concavo-convex portion 157 may be chemically patterned using a chemical solution or the like.

  Further, a reflecting member having a refractive index different from that of the light guide plate 150 may be embedded in the light guide plate 150. In this case, the light is irregularly reflected at the boundary surface between the reflecting member and the light guide plate 150, so that the light can be emitted toward the front of the pachinko machine 10. In addition, if it is set as the structure which embeds many comparatively small diameter beads as a member for reflection, the boundary surface between the member for reflection and the light-guide plate 150 can be ensured as much as possible, and the pachinko machine 10 is interposed via the member for reflection. The amount of light emitted toward the front can be increased.

  (16) In the above embodiment, the sound lamp control board 272a controls the LED 154 for the light guide plate, but this may be changed. For example, the main control board 271a and the display control board 278 may be configured to control the light guide plate LEDs 154.

  (17) In the above embodiment, the partition line DL is displayed by the light emitted from the light guide plate 150. However, this may be changed. For example, the light may be rendered by the light emitted from the light guide plate 150. Thereby, it can produce with the light radiated | emitted from the light guide plate 150 according to the display content on the display screen 161, and can raise the attention degree to a game.

  (18) In the above embodiment, the continuous light emitting region is formed by forming the series of concave and convex portions 157, but this may be changed. For example, a discontinuous light emission region may be provided by intermittently forming the uneven portion 157.

  (19) In the above embodiment, the symbol display device 160 having the display screen 161 having a larger area than the game area 103 is provided, but this may be changed. For example, a symbol display device 160 having a display screen 161 having a slightly smaller area than the game region 103 may be provided, or a symbol display device 160 having a display screen 161 having substantially the same area as the game region 103 may be provided. . In addition, in the configuration in which the symbol display device 160 having the display screen 161 having the same area as the game area 103 or wider than the game area 103 is provided, a part of the outer periphery side of the game area 103 is located in the front area of the display screen 161. You may arrange | position the symbol display apparatus 160 so that it may not enter.

  (20) In the above embodiment, when the reach effect is performed on the display screen 161 in an enlarged display, the enlarged display is performed so as to be represented in most areas in the game area 103. If the display area is wider than the area where the partition line DL is displayed, the enlarged display may be performed in an area narrower than the above embodiment. That is, as long as the variable display area of the symbol is enlarged and reduced in enlarged display and reduced display, the size of the area in each display is arbitrary.

  (21) In the above embodiment, when the reduced display is performed on the display screen 161, the background image of the uniform color is displayed outside the area where the reduced display is performed. Also good. For example, it may be configured to display a character related to the model of the pachinko machine 10 outside the area where the reduced display is performed, or may be configured to display a landscape or the like. Further, the displayed content is not limited to a still image, and a moving image by a character or the like may be displayed.

  (22) In the above embodiment, the main control board 271a is configured to determine a fine combination of stop symbols, a symbol variation pattern, and a reach effect in the symbol display device 160, but this may be changed. For example, the sound lamp control board 272a and the display control board 278 may be configured to determine a fine combination of stop symbols, a pattern variation pattern, a reach effect, and the like. In this case, the main control board 271a displays information indicating whether a jackpot that is in a probable change state, a jackpot that is in a normal state or no jackpot occurrence, and a color switching display that is displayed on the first specific lamp unit 117. A display command including time information is output to the sound lamp control board 272a or the display control board 278. The board 272a or the control device 278 that has received the display command determines a fine combination of stop symbols, a symbol variation pattern, and a reach effect based on the display command, and the symbol variation within the range of the switching display time. Control the display. With this configuration, the processing load on the main control board 271a can be reduced.

  (23) Although the first and second specific lamp portions 117 and 118 are provided in the above embodiment, these may not be provided. Moreover, in the structure which provides the 1st, 2nd specific lamp parts 117 and 118, the arrangement position is not limited to the position in the said embodiment, It is arbitrary.

  (24) In the above embodiment, the sound lamp control board 272a controls the display control board 278 based on the command from the main control board 271a, but instead of this, the command from the main control board 271a is changed to the command. Based on this, the display control board 278 may control the sound lamp control board 272a. Further, instead of providing the display control board 278 and the sound lamp control board 272a separately, the functions of both boards may be provided on one board. In this case, the board controls the symbol display device 160 and the light guide plate LED 154 based on a command from the main control board 271a.
