As shown in FIG. 1, a guide rail 12 is attached to the front surface of the game board 11, and a game ball can flow down in a circular game area R <b> 1 surrounded by the guide rail 12. A display device 13 is provided almost at the center of the game area R1, and below the display device 13 is a start winning section 14, a big winning opening 103 (corresponding to the “winning opening” of the present invention) and an out opening 16. These are arranged side by side in order from the top. A ramp windmill 17, a start gate 18, and a windmill 19 are provided in order from the top on both the left and right sides of the display area 13 in the game area R1. In addition, a pair of side prize winning portions 20 and 20 are provided on both the left and right sides of the grand prize winning opening 103. Further, in addition to these winning holes and the like, a plurality of nails (not shown) stand up in the game area R1.

Each required part of the game board 11 will be described.
The side winning portions 20 and 20 have a so-called pocket structure, and are opened upward in such a size that only one game ball can enter. When the player enters the side winning units 20 and 20, the game ball is taken into the back side of the game board 11, and a predetermined number (for example, five) of the prize balls are paid out to the upper plate 27A instead.

  The start gate 18 has a gate-like structure through which game balls can pass through, and the passed game balls are detected by a detection switch built in the start gate 18. Based on the detection signal, the normal symbol is variably displayed on the display device 13.

  The start winning portion 14 has a so-called pocket structure and is opened upward, and movable wing pieces 14C and 14C are provided on both sides of the opening. Both the movable wing pieces 14C, 14C are always in an upright state, and the opening sandwiched between the two movable wing pieces 14C, 14C is sized to accommodate just one game ball. When a predetermined condition is established and a solenoid (not shown) provided on the back of the game board 11 is driven, the movable wing pieces 14C and 14C are tilted sideways for a predetermined period (for example, 0.4 seconds) ( The state of FIG. Then, the game ball flowing down in the vicinity of the start winning portion 14 is received by the movable wing piece 14C and guided to the opening, so that the game ball can easily win the start winning portion 14.

  A game ball won in the start winning section 14 is detected by a detection switch provided in the start winning section 14. Then, for example, ten game balls are paid out to the upper plate 27A as prize balls, and special symbols are displayed in a variable manner on the display device 13.

  The grand prize winning opening 103 has a horizontally long rectangular shape and is opened forward, and is always closed by the rotating door 120. When the game is in the “hit state”, the door solenoid 134 (corresponding to the “operating means” according to the present invention) provided on the back of the game board 11 is driven, and the turning door 120 is set to the big prize opening 103. It is turned around the lower side and is in an open posture that falls to the front side over a predetermined period (state of FIGS. 9 and 11). As a result, the grand prize winning opening 103 is opened, and the game ball is received by the rotating door 120 protruding in front of the game board 11 and can enter the grand prize winning opening 103.

  The game balls won in the big prize opening 103 are detected by a detection switch 132C (see FIG. 8) provided in the big prize opening 103, and for example, 15 game balls are paid out as a prize ball for each prize. It is. When the predetermined condition is satisfied (for example, whether the opening time of the revolving door 120 has reached 30 seconds or 10 game balls have been won in the big winning opening 103), the revolving door 120 is turned on the game board 11. It turns to the closed position, and the big winning opening 103 is closed, so that the game ball cannot enter (state shown in FIGS. 8 and 10).

  As shown in FIGS. 8 and 9, in the pachinko gaming machine 10 of the present embodiment, a protective plate member 110 is provided between the game board 11 and the glass plate 150 in front of the special winning opening 103. The protection plate member 110 is entirely made of a transparent synthetic resin, and covers the special winning opening 103 and the rotary door 120 so as to be visible from the front. The pivot door 120 pivots between an open posture and a closed posture inside the protective plate member 110, receives the game ball that has entered the protective plate member 110, and guides it to the big prize opening 103. The protection plate member 110 prevents the game ball from being caught between the front end portion of the revolving door 120 (see FIG. 9) and the glass plate 150 in the open posture. In addition, since the space | interval of the protection board member 110 and the front-end | tip part of the rotation door 120 in an open attitude | position is less than the radius of a game ball (for example, 1-2 mm), the rotation door which became an open attitude | position A game ball is not bitten between the front end portion of 120 and the protection plate member 110.

  Further, the protection plate member 110 is disposed at a position near the glass plate 150 between the glass plate 150 and the game board 11. Specifically, the distance S1 (see FIG. 8) between the glass plate 150 and the inner surface of the protection plate member 110 is less than the radius (5.5 mm) of the game ball. This prevents the game ball from entering between the glass plate 150 and the protection plate member 110, and even if the game ball falls on the protection plate member 110, the center of gravity of the game ball is the protection plate member. Since it is located on the game board 11 side from the inner surface of 110, the game ball surely falls inside the protection plate member 110. That is, the game ball does not stop while being placed on the protection plate member 110.

  The display device 13 has a frame-shaped decorative frame 23 (see FIG. 1) attached from the front side of the game board 11 to an opening K1 (see FIG. 4) penetratingly formed in the center of the game board 11. And a liquid crystal module (not shown) (in detail, a TFT-LCD module) attached from the rear side of the game board 11. As shown in FIG. 1, the player can view the display screen 24 of the liquid crystal module through the display window 23 </ b> W formed in the decorative frame 23.

  Here, the display screen 24 is divided into a special symbol display area 24A for displaying special symbols and a normal symbol display area 24B for displaying normal symbols. Specifically, as shown in FIG. 1, the normal symbol display area 24B is provided in the lower left corner of the display screen 24, and the other part of the display screen 24 is a special symbol display area 24A.

  In the normal symbol display area 24B, for example, a plurality of types of normal symbols representing numbers “0” to “9” are displayed, and usually a predetermined type is stopped and displayed. When the detection switch provided in the start gate 18 detects the passing of the game ball, for example, after the normal symbol is variably displayed over a predetermined period, the predetermined normal symbol is stopped and displayed. Then, when the normal symbol stopped and displayed is a predetermined winning symbol (for example, an odd symbol), the movable wing pieces 14C and 14C provided in the start winning portion 14 are tilted sideways. The normal symbols displayed in the normal symbol display area 24B are not limited to numbers, and may be alphabets or symbols.

  On the other hand, normally, three special symbols 13A, 13B, and 13C are displayed side by side in the special symbol display area 24A. Each of these special symbols 13A, 13B, and 13C is composed of, for example, a plurality of types that express numbers from “0” to “11”. Usually, each special symbol 13A, 13B, and 13C has a predetermined value. Various types are stopped and displayed in the special symbol display area 24A. Then, when a game ball wins the start winning portion 14, each special symbol 13A, 13B, 13C is scrolled up and down, and after a predetermined time, for example, the left special symbol 13A, the right special symbol 13C, and the middle special symbol 13B. Are displayed in order of stop. At this time, for example, when the three special symbols 13A, 13B, and 13C are all the same symbol, that is, when they are all in a rough state, the game is in a “hit state”, the big winning opening 103 is opened, and the game ball is released. Winning is possible.

  When the special symbols 13A, 13B, and 13C are displayed in a varying manner in the special symbol display unit 24A or when the game is in the “hit state”, when the winning prize is received in the starting winning unit 14, the special symbols 13A, The variable display of 13B and 13C is not started immediately but is temporarily suspended. Then, after the special symbols 13A, 13B, and 13C are stopped or displayed, or after the “hit state” is finished, the variable display for the suspended amount is started. In the present embodiment, the maximum number of hold times is four. This completes the description of the overall configuration of the game board assembly.

  By the way, in the pachinko gaming machine 10 of the present embodiment, the present invention is applied to the big winning device 100 having the big winning opening 103.

As shown in FIG. 5, the back wall 132F facing the winning prize opening 103 side in the ball passage 132A is inclined obliquely toward the ball discharge port 132B, and as shown in FIG. The bottom surface 132D of 132A is inclined so as to descend toward the ball discharge port 132B. Thereby, the game ball that has entered the ball passage 132A can be smoothly guided to the rear side and discharged from the ball discharge port 132B. Here, the game balls discharged from the ball discharge port 132B to the outside of the winning device main body 130 are collected to the game hall side through a ball collection duct (not shown).

  In the ball passing structure 130 </ b> A, the front door opening 132 </ b> E facing the prize winning opening 103 is provided with a pivot door 120 so as to be pivotable. The revolving door 120 is formed of, for example, a transparent synthetic resin and has a horizontally long rectangular plate 123 having substantially the same shape as the winning prize opening 103, and side plates 121 integrally formed at both ends in the longitudinal direction. 121. In addition, for example, an opaque seal SL on which an effect design is printed is affixed to the outer surface 123G of the long plate portion 123 that faces forward when the rotary door 120 is in the closed position ( See FIG.

  As shown in FIG. 12, an arm 121 </ b> A extends from the lower end portion of the side plate portions 121, 121 in the rotary door 120. As shown in FIG. 10, shafts 131 and 131 that are horizontally fixed to the ball passage structure 130 </ b> A pass through the arm 121 </ b> A, and the pivot door 120 can be rotated by the shafts 131 and 131. Is pivotally supported.

  As shown in FIG. 11, of the side plate parts 121, 121 provided in the rotary door 120, one side plate part 121 (for example, the right side plate part 121) has a stopper that stops the rotary door 120 in an open posture. The part 120S is integrally formed. The stopper portion 120S protrudes laterally from the side plate portion 121, and abuts against the opening edge of the grand prize winning opening 103 when the rotating door 120 falls forward by a predetermined angle (for example, about 50 degrees) from the closed posture. It is like that. As a result, when the pivot door 120 is in the open posture, the inner surface 123N of the long plate portion 123 is held in an inclined posture so that the inner surface 123N faces upward and goes down toward the grand prize winning opening 103. Then, the game ball that has dropped onto the inner surface 123N of the long plate portion 123 flows smoothly toward the back side (the ball passage 132A) of the special winning opening 103 due to the inclination.

  Of the side plate portions 121, 121, the portion protruding to the inner surface 123N side of the long plate portion 123 is the door protrusion 121C of the present invention. As shown in FIG. 11, the door protrusion 121 </ b> C stands upright at a right angle to the inner surface 123 </ b> N of the long plate portion 123. An inclined surface 121D that is inclined toward the center side in the left-right direction of the rotary door 120 is formed at the upper edge of the door protrusion 121C. The inclined surface 121 </ b> D is inclined so as to descend toward the grand prize winning opening 103 when the rotating door 120 is in the open posture. By this inclined surface 121D, the game ball that has dropped onto the revolving door 120 in the open posture can be guided to the center side in the left-right direction of the revolving door 120 and to the winning prize opening 103 side.

  The pivot door 120 is pivoted between the closed posture and the open posture by the door solenoid 134 described above. That is, when the exciting coil 134A provided in the door solenoid 134 is energized, the plunger 134B is attracted by the exciting coil 134A and moves rearward while compressing and compressing the compression coil spring 134C. The linear motion of the plunger 134B is converted into a rotational motion by a motion conversion mechanism (not shown) connected to the plunger 134B, and is transmitted to the rotary door 120 that opens and closes the big prize opening 103. Then, the turning door 120 is turned around the shaft bodies 131 and 131 to be in an open posture, and the special winning opening 103 is opened (the state shown in FIGS. 9 and 11). Further, the light of the LED 133B mounted on the circuit board 133A can be visually recognized by the player through the protective plate member 110, the opened large winning opening 103, and the ball passing structure 130A on the back side.

  On the other hand, when the energization to the exciting coil 134A is stopped, the plunger 134B moves away from the exciting coil 134A, that is, the front side by the elastic force of the compression coil spring 134C. The linear motion of the plunger 134B is converted into a rotational motion by a motion conversion mechanism (not shown) and transmitted to the rotary door 120. Then, the turning door 120 is turned around the shaft bodies 131 and 131 to be in a closed posture, and the special winning opening 103 is closed (the state shown in FIGS. 8 and 10). At this time, the long plate portion 123 of the pivot door 120 is retracted to the inside of the big prize opening 103 (see FIG. 8) and does not come into contact with the game ball flowing down the front side of the big prize opening 103. Further, the light of the LED 133B is blocked by the seal SL attached to the long plate portion 123, and cannot be visually recognized by the player.

  As shown in FIG. 14, the protection plate member 110 provided in front of the grand prize winning opening 103 has a horizontally long flat plate shape. Specifically, the upper side 110J central portion and the lower side 110K of the protective plate member 110 extend in parallel and horizontally with each other, and the upper side 110J central portion is directed toward the rear surface (the surface facing the big prize opening 103). A tapered surface 114 that is inclined downward is formed. Further, both end portions of the upper side 110J are inclined downward toward the side, and both sides 110S and 110S are inclined and gently curved so as to approach each other toward the lower side.

  A concavo-convex pattern having a predetermined design is formed on the front surface of the protection plate member 110, that is, on the peripheral edge of the surface facing the front of the pachinko gaming machine 10. The central portion is a smooth flat surface, through which the grand prize winning opening 103 and the rotary door 120 can be visually recognized.

  On the other hand, fixed support columns 111 and 111 for fixing the protective plate member 110 are integrally formed on the rear surface of the protective plate member 110, that is, on both ends in the left-right direction of the surface facing the winning prize opening 103. The fixed column 111 has a cylindrical structure and stands upright at a right angle to the protective plate member 110. A female thread is formed on the inner peripheral surface of the tip of the fixed support 111.

  On the rear surface of the protective plate member 110, a pair of intrusion prevention walls 112 and 112 (corresponding to the “entry prevention member” of the present invention) are formed to project from the fixed support columns 111 and 111 in the center side portion in the left-right direction. These intrusion prevention walls 112 stand perpendicular to the rear surface of the protective plate member 110. Further, the upper edge portion 112 </ b> B of the entry preventing wall 112 is perpendicular to the protective plate member 110, and the lower edge portion 112 </ b> A is inclined with respect to the protective plate member 110. In addition, projecting portions 113, 113 are formed so as to protrude above the intrusion prevention wall 112 on both ends of the protective plate member 110.

  A pair of side wall portions 140 and 140 are provided between the protection plate member 110 and the special winning opening 103. As shown in FIG. 10, the side wall portions 140 and 140 are provided at both left and right ends of the big winning opening 103 in the front unit 101 and project forward from the front surface of the laying plate 101F. And the protection board member 110 is passed between the front surfaces 140Z of this side wall part 140,140. Here, the side wall portions 140 and 140 restrict the inflow of game balls from both ends of the big winning opening 103 in the left-right direction.

  Of the side walls 140, the vertical surfaces 140T that face each other across the prize winning opening 103 form a flat surface that is perpendicular to and parallel to the game board 11 surface, and the front surface 140Z is a flat surface that is parallel to the game board 11 surface. It has a surface. Further, the outward surface 140S opposite to the vertical surface 140T of the side wall portion 140 is inclined so as to approach each other as it goes downward, and the upper surface 140J is inclined so as to be lowered as it is away from the grand prize winning opening 103. ing.

  Further, as shown in FIG. 10, so-called bowl-shaped upper wall portions 145 and 145 are integrally formed at the upper ends of the side wall portions 140 and 140. That is, the upper wall portion 145 has an upper wall 146 that extends from the upper end portion of the side wall portion 140 so as to approach each other (in other words, toward the central portion in the left-right direction of the prize winning opening 103), and the upper wall The vertical wall 147 extends vertically downward from the front end portion of the 146 and reaches the upper edge of the prize winning opening 103. The interval between the vertical walls 147 of the upper wall portions 145 and 145 is narrower than the width dimension in the left-right direction of the special winning opening 103 (the interval between the vertical surfaces 140T of the side wall portions 140 and 140). Specifically, while the width dimension of the special winning opening 103 is about 69 mm, the interval between the vertical walls 147 is about 54 mm. These upper wall portions 145 cover both end portions of the winning prize opening 103 from above and cover both side plate portions 121 of the rotary door 120 from above (see FIG. 11). Further, the upper surface 145J of the upper wall portion 145 is inclined so as to be lowered as it is away from the prize winning opening 103, and is flush with the upper surface 140J of the side wall portion 140 and has substantially the same gradient. Accordingly, the game ball that has dropped onto the upper surface 145J of the upper wall portion 145 rolls toward the side away from the grand prize winning opening 103 due to its inclination, and passes to the side of the big winning prize opening 103 through the upper surface 140J of the side wall 140. Flow down. By adopting such a configuration, the number of game balls flowing into the side wall portions 140, 140, that is, the inside of the protective plate member 110, can be suppressed as compared with the case where the upper wall portion 145 is not provided. ing.

  Here, the protection plate member 110 is fixed to the side wall portions 140 and 140 as follows. That is, the fixed columns 111 and 111 of the protection plate member 110 are inserted into the circular holes 141 and 141 opened to the front surfaces 140Z of the side wall portions 140 and 140, and the rear surface of the protection plate member 110 is inserted into the side wall portions 140 and 140. The protection plate member is formed by engaging screws (not shown) that pass through the laying plate 101F from the rear surface side of the front unit 101 to the front ends of the fixed columns 111 and 111 in this state. 110 is passed between the front surfaces 140Z of the side wall portions 140. At this time, a pair of protrusions 113 and 113 formed on the rear surface of the protection plate member 110 are spaces 145K and 145K surrounded by the upper wall 146 and the vertical wall 147 of the upper wall portions 145 and 145 (see FIG. 10). ).

  Now, in a state where the protection plate member 110 is attached to the side wall portions 140, 140, the positional relationship between the entry preventing wall 120, the rotary door 120, and the upper wall portion 145 is as follows. That is, as shown in FIG. 6, the entry preventing wall 112 is disposed directly below the vertical wall 147 of the upper wall portion 145, and protrudes toward the grand prize winning opening 103 as shown in FIGS. 8 and 9. Further, both side surfaces in the thickness direction of the vertical wall 147 and both side surfaces in the thickness direction of the entry preventing wall 112 are flush with each other. Further, the entrance prevention wall 112 is disposed on the center side in the left-right direction of the big prize opening 103 with respect to the door projection 121C of the rotary door 120, and the interval S2 between the entry prevention wall 112 and the door projection 121C (see FIG. 6). ) Is smaller than the diameter (11 mm) of the game ball. Therefore, the game ball is not sandwiched between the entry preventing wall 112 and the door protrusion 121C. Further, as shown in FIG. 13, the intrusion prevention wall 112 is disposed outside the rotation range of the rotation door 120. Specifically, the lower edge portion 112A of the ingress prevention wall 112 facing the revolving door 120 side is rotated when the front end of the revolving door 120 rotates between the closed posture and the open posture. The arc shape is concentric with the locus Q1 and has a slightly larger diameter than the turning locus Q1 of the turning door 120. With such a configuration, it is possible to make the approach prevention wall 112 and the pivot door 120 as close as possible while avoiding mutual interference between the approach prevention wall 112 and the pivot door 120. In addition, the distance between the edge of the door protrusion 121C facing the entry prevention wall 112 in the open posture and the lower edge 112A of the entry prevention wall 112 is smaller than the diameter (11 mm) of the game ball at the maximum. A game ball does not enter between the portion 121C and the entry prevention wall 112.

The configuration of the pachinko gaming machine 10 of the present embodiment is as described above, and the operation will be described next.
When the player operates the operation knob 28, the game ball is ejected to the upper portion of the game area R1 of the game board 11. The game ball is changed in direction by hitting an accessory (the ramp windmill 17, the windmill 19, the display device 13, etc.) provided in the game area R1, a obstacle nail, and the like, and travels below the game area R1 through a random route.

  When the game ball passes through the start gate 18 in the middle of flowing down the game area R1, the normal symbol variation display is started in the normal symbol display area 24B of the display screen 24. Ordinary symbols are displayed in a stopped state after being variably displayed over a predetermined time. Then, when the normal symbol is stopped with an odd number, the movable wing pieces 14C, 14C provided in the start winning portion 14 fall sideways. Then, a part of the game ball flowing down the game area R1 is received by the movable wing pieces 14C and 14C and guided to the opening of the start winning portion 14. That is, it becomes easier for a game ball to enter the start winning portion 14 than in the normal case.

  When the player enters the start winning portion 14, the game ball is taken into the back side of the game board 11, and instead, for example, 10 game balls are paid out to the upper plate 27A, and in the special symbol display area 24A of the display screen 24. Scroll display of special symbols 13A, 13B, 13C is started.

  The special symbols 13A, 13B and 13C are scrolled and displayed for a predetermined time, and then stopped and displayed one by one. Then, when the three special symbols 13A, 13B, and 13C that are stopped and displayed are all the same (bottle), the revolving door 120 provided in the large winning device 100 is held in an open posture for a predetermined period and is awarded a big prize. The mouth 15 opens. At this time, the game ball that has entered the inside of the protection plate member 110 is received by the revolving door 120 in the open posture and guided to the special winning opening 103. When a game ball enters the big prize opening 103, the game ball is taken into the back side of the game board 11, and 15 prize balls are paid out to the upper plate 27A instead.

  Here, in the open position, the revolving door 120 is held in an inclined position so that the inner surface 123N of the long plate portion 123 that receives the game ball is lowered toward the prize winning opening 103, so that the received game ball can be smoothly received. It is possible to guide to the back side (the ball passage 132A) of the grand prize winning opening 103.

  Now, a part of the game ball flowing down the game area R1 collides with the side wall portion 140 or the upper wall portion 145, and flows down without flowing into the protective plate member 110. Specifically, as shown in FIG. 15, the game ball that has dropped on the upper surface 140J of the side wall 140 rolls away from the big prize opening 103 due to the inclination of the upper surface 140J, and the side of the side wall 140 It flows down toward the direction. In addition, the game ball that has fallen on the upper surface 145J of the upper wall portion 145 also passes through the upper surface 140J of the rolling side wall portion 140 so as to move away from the winning prize opening 103 due to the inclination of the upper surface 145J, to the side of the side wall portion 140. It flows down toward. Thereby, the number of game balls entering the inside of the protection plate member 110 can be reliably suppressed. In FIG. 15, the protective plate member 110 is indicated by a broken line for convenience of explanation.

  Here, as shown in FIG. 15, the upper wall portion 145 covers both ends of the big prize opening 103 and both ends of the rotary door 120 from above, so that the entrance (inward to the inside of the protection plate member 110 ( The laterally long rectangular opening surrounded by the protective plate member 110, the upper wall portions 145 and 145, and the laying plate 101F and opened upward is the inner side of the protective plate member 110 (the protective plate member 110 and the side wall portions 140 and 140). It is narrowed with respect to the enclosed part). Thereby, compared with the case where the upper wall part 145 is not provided, the number of game balls flowing into the inner side of the protective plate member 110 is suppressed, and a margin can be made inside the protective plate member 110. As a result, the game balls that have entered the inside of the protection plate member 110 smoothly flow to the back side of the special winning opening 103.

  By the way, most of the game balls received by the rotary door 120 roll from the dropped position to the prize winning opening 103 as they are. Some roll to the end side in the left-right direction. Here, the game ball that has rolled to the end side of the revolving door 120 when the revolving door 120 is in the open posture is an entry prevention wall disposed between both ends of the revolving door 120 and the upper wall portion 145. 112 or any of the door protrusions 121 </ b> C facing the upper wall 145. Thereby, a game ball does not enter between the upper wall portion 145 and the end portion of the revolving door 120 in the open posture.

  As described above, according to the pachinko gaming machine 10 of the present embodiment, the upper wall portions 145 disposed on both ends in the left-right direction of the large winning opening 103, the both ends of the large winning opening 103 and the rotary door 120 are arranged. By covering both ends from above, the entrance to the inside of the protection plate member 110 becomes narrower than the inside of the protection plate member 110. As a result, the game balls that have entered the inside of the protective plate member 110 smoothly flow toward the back side of the special winning opening 103, and it becomes possible to prevent clogging of the balls inside the protective plate member 110. In addition, the protective plate member 110 is provided with an entry preventing wall 112 that prevents the game ball from entering between the upper wall portion 145 and both ends of the revolving door 120 in the open posture. Occurrence of a problem that a game ball is sandwiched between the upper wall portion 145 and the rotary door 120 can be prevented.
