  A guide rail 10 is laid on the front surface of the game board 3, and a game area 3 a is formed by the guide rail 10. In addition, a variable winning device 11 as a central prize is provided in the approximate center of the game area 3a, and a plurality of special winning ports 12a and 12b are provided below the variable winning device 11. Further, the game area 3a is provided with a general winning port 14, a windmill 15 for changing the direction in which the hit ball flows and an obstacle nail 16, and the special winning ports 12a and 12b and the winning port 14 are won at the lower end of the gaming region 3a. An out port 17 for discharging the pachinko balls that have not been used is provided. The special prize openings 12a and 12b are prize openings for opening a movable piece 18 of a variable prize apparatus 11 to be described later. Each of the special prize openings 12a and 12b is provided with a detection switch 13. Is opened and closed twice, and the movable piece 18 is opened and closed once when a game ball is won in the left and right specific winning openings 12b.

  As shown in FIG. 2 to FIG. 5, the variable winning device 11 has a mounting plate 20 that is attached to the surface of the game board 3, and a window opening 21 is formed at substantially the center of the mounting plate 20, and communicates with the window opening 21. Thus, a concave chamber 27 constituting a winning area is formed. A decorative member 22 is projected along the upper portion of the window opening 21, and a lower frame 23 is projected along both side edges and the lower side of the window opening 21, so that the decorative member 22 and the lower frame 23 are projected. A pair of movable pieces 18 are provided so as to be openable and closable so that pachinko balls cannot enter the concave chamber 27 in a normal state. In the lower frame 23, a ball receiving shelf 28 for guiding the game ball received by the movable piece 18 to the rear of the concave chamber 27 so as to face the concave chamber 27 is gently inclined downwardly and provided. A specific winning area 25 is formed on the lower frame 23 located on the lower side by a pair of projecting pieces 24, and areas on both the left and right sides of the specific winning area 25 are formed as general winning areas 26. The specific winning area 25 is provided with a winning ball detector 25a. When a game ball is won in the specific winning area 25 and is detected by the winning ball detector 25a, a so-called “hit” is made, and the movable piece 18 is opened and closed to make a large amount. It becomes a gaming state where a winning ball is generated. The movable piece 18 is connected to a solenoid at the rear end of the shaft portion via a link member, and is opened and closed by driving the solenoid.

  The concave chamber 27 is provided with a ball guiding device 29 for guiding the game ball to the specific winning area 25 or the general winning area 26. As shown in FIG. 4, the ball guiding device 29 includes a plane spiral ball runway 30 and a drive unit 31 that moves up and down at least one end (the outer end 30 a in this embodiment) of the ball runway 30. ing. The ball runway 30 has a shallow groove that holds the game ball so that it does not spill in the length direction, and is formed by winding a strip plate material 32 made of a synthetic resin having substantially the same width as the game ball in a plane spiral shape. . The inner end 30b of the ball runway 30 is fixed to the shaft portion 19 protruding from the bottom of the concave chamber 27, and the height position of the outer end 30a is made higher than the height position of the inner end 30b. By making it lower, the inclination direction of the ball runway 30 changes, so that the game ball can flow down toward the outer end 30a or the inner end 30b. The spherical runway 30 is formed with a spiral gap so that the band plate material 32 does not overlap in plan view, so that the height position of the outer end 30a is positioned above or below the inner end 30b. The inclination direction of the ball runway 30 can be changed, and the whole shape of the ball runway 30 can be made into a mortar shape or a mountain shape. Then, by driving the driving means 31, the ball runway 30 is elastically bent by changing the height positions of the outer end 30 a and the inner end 30 b of the ball runway 30, and the ball runway 30 is inclined. The direction is changed so that the flow direction of the game ball changes. Further, the rear end of the ball receiving shelf 28 is provided behind the center of the ball runway 30, and a game ball falling from the ball receiving shelf 28 is received behind the center of the ball runway 30. Note that the band plate material 32 does not necessarily have the same diameter width as the game ball, but may have a width that supports the ball center of the game ball. Further, the rear side surface of the concave chamber 27 is used as a mirror surface, and a game ball rolling in the back of the ball runway 30 is projected on the mirror surface so that the player can clearly see the game ball rolling in the back. Also good. Further, the rear surface of the concave chamber 27 is a magic mirror, and a lighting device such as a lamp or LED is arranged on the rear surface thereof. Alternatively, the magic mirror may be mirror-finished so that the player can clearly see the game ball that rolls behind the ball runway 30.

  The drive means 31 includes a stepping motor 33, a link member 34, and a cam member 36 as an electrical drive source. On the motor shaft of the stepping motor 33, a cam member 36 provided with an engaging pin 35 eccentric is fixed. The link member 34 has a shaft pin 37 provided at one end engaged with a through hole 39 of an attachment piece 38 that hangs down from the lower surface of the outer end 30 a of the ball runway 30. Then, the stepping motor is engaged with the engagement pin 35 of the cam member 36 in the shaft hole 41 on the other end of the link member 34 on the lower surface side of the recess chamber 27 through the guide hole 40 opened at the bottom of the recess chamber 27. By driving 33, the outer end 30a of the ball runway 30 is moved in the vertical direction. It is preferable to provide a detection switch that detects the rotation of the cam member 36 or the vertical movement of the cam member 34 and detects the highest position and the lowest position of the outer end 30a.

  Next, the operation of the variable winning device 11 will be described. By operating the operation handle 8, the game ball of the hit ball supply tray 5 is driven into the game area 3 a, won in one of the special winning openings 12 a, 12 b and detected by the detection switch 13, thereby becoming a chain line in FIG. 2. As shown, the movable piece opens and closes once or twice. When a game ball is received by the movable piece 18 during the opening / closing operation, the game ball is guided from the ball receiving shelf 28 to the game ball guiding device 29. At this time, the outer end 30a of the ball runway 30 of the game ball guidance device 29 is always moved up and down by the driving of the stepping motor 33, and the inclination direction of the ball runway 30 is changed. The game ball guided from the movable piece 18 to the ball receiving shelf 28 is located on the rear side from the center of the ball runway 30 because the rear end of the ball receiving shelf 28 is located on the rear side from the center of the ball runway 30. It is received by falling. The flow direction of the game ball changes according to the fall timing from the ball receiving shelf 28. In other words, when the game ball falls from the ball receiving shelf 28 when the outer end 30a of the ball runway 30 is lowered below the inner end 30b as shown in FIG. The game balls received by the player flow down the ball runway 30 while rotating in the outward direction toward the outer end 30a in the direction of arrow A in FIG. 4, and are guided from the outer end 30a toward the general winning area 26. The In addition, when the game ball falls from the ball receiving shelf 28 when the outer end 30a of the ball runway 30 is raised above the inner end 30b as shown in FIG. The ball runs down the ball runway 30 while rotating inward toward the inner end 30b in the direction of arrow 4b, and is guided toward the specific winning area 25 from the inner end 30b.

  Then, when the game ball wins the specific winning area 25 and is detected by the winning ball detector 25a, it becomes a “hit” state where the player can acquire a large amount of prize balls, and the movable piece 18 repeatedly opens and closes a predetermined number of times. The game ball is guided to the winning area. A predetermined round (for example, 16) is obtained on the condition that a predetermined number (for example, 10) of game balls wins the specific winning area 25 and the general winning area 26 as one round, and on the condition that the gaming balls have won in the specific winning area 25. Round) The special game state in which the movable piece 18 opens and closes is continued. At the time of this continuation, the game ball guidance device 29 first drives the stepping motor 33 to stop the ball runway 30 with the outer end 30a moved upward, and the entire shape of the ball runway 30 is mortar-shaped. The game ball is guided toward the inner end 30b. When the winning ball detector 25a detects the winning of the game ball by being guided from the inner end 30b of the ball runway 30 to the specific winning area 25, the stepping motor 33 is driven and the outer end 30a of the ball runway 30 is detected. The ball runway 30 is made to have a mountain shape so that the game ball flows down in the outward direction and is guided from the outer end 30a of the ball runway 30 to the general winning area 26. When a predetermined number of winning balls are detected by a count sensor (not shown), the opening / closing operation of the movable piece 18 is once stopped to prevent the game balls from being received in the winning area. Then, on the condition of winning in the specific winning area 25, the opening and closing of the movable piece 18 is repeated again and the stepping motor 33 of the game ball guiding device 29 is driven to move the outer end 30a upward, It is easy to win the specific winning area 25 so that the side end 30b is lower than the outer end 30a. During the game, by moving the outer end 30a of the ball runway 30 upward so that the ball runway 30 gradually decreases inward, the ball runway 30 becomes a shallow mortar shape with the upper side expanded, The game ball received by falling on the ball runway 30 does not jump out of the ball runway 30 even if it bounces on the ball runway 30 and rolls inward. It will flow out from the end 30b. Conversely, the game led from the ball receiving shelf 28 to the ball runway 30 in a state where the outer end 30a of the ball runway 30 is lowered below the inner end 30b and the entire shape of the ball runway 30 is mountain-shaped. The ball is led to the general winning area 26 while showing various modes such as going around the ball runway 30 and flowing out from the outer end 30a, and the ball runway 30 flexing and jumping and falling.

  In this way, since the ball runway 30 is formed with elasticity, a game ball falling from the ball receiving shelf 28 jumps on the ball runway 30 or bends the ball runway 30 while being unexpected. It shows a certain movement and can increase the interest of the player. Further, when the driving means 31 is always moved to change the inclination direction of the ball runway 30, if a plurality of game balls roll on the upper surface of the ball runway 30, the stepping motor 33 drives the ball. When the inclination direction of the runway 30 is changed, the game balls on the ball runway 30 may be bumped and thrown away, or may be lifted in the opposite direction to the inclination direction. In particular, when the ball runway 30 changes from an inward slope to an outward slope, the flow velocity of the game ball flowing down the inner side of the ball runway 30 is fast, and thus the force that flows backward even if the slope direction changes suddenly. However, it may flow out from the inner end 30b as it is, and the interest of the player is improved by the unpredictable movement of the game ball. Further, in order to make the game more interesting, an obstacle that changes the flow of the game ball flowing down the ball runway 30 is provided at a position that interferes with the flow of the game ball on the strip 32 constituting the ball runway 30. You may do it. For example, as shown in FIG. 4, a slight depression 30 c is provided as an obstacle, and depending on the inclination angle of the ball runway 30, the game ball flowing down the ball runway 30 is temporarily stopped at the depression 30 c and the ball runway The flow can be resumed by being pushed by another game ball flowing down 30, the flow can be resumed due to the inclination angle of the ball runway 30 being tight, or an unexpected movement can be achieved. Further, a slight protrusion 30d is provided as an obstacle, and the flow velocity flowing down the ball runway 30 causes the protrusion 30d to flow as it is without being affected by the protrusion 30d or the flow path is changed by the protrusion 30d. Since it falls to the inside or the outside of the runway 30, the player can fully enjoy the movement of the game ball. In addition, although the said recessed part 30c and the protrusion 30d were provided in the center of the strip | belt board material 32, it shifted and provided in the width direction of the strip | belt board material 32 so that it may interfere with the flow velocity of the game ball which flows down the ball runway 30. It may be. Furthermore, the place where the obstacle is provided and the number and shape of the obstacle are not limited. Moreover, you may make it mix the hollow part 30c and the protrusion 30d on the ball runway 30. FIG.

  6 and 7 show another embodiment of the ball runway. The difference from the above embodiment is that the passage material constituting the ball runway is different. explain. In this embodiment, the ball runway 30 is formed by winding a stainless wire 42 in a spiral shape in plan view as shown in FIG. 6, and the space between adjacent wires 42 is wider than the radius of the game ball and narrower than the diameter. The game ball is supported between the adjacent wire rods 42 and flows down. According to the present embodiment, the ball runway 30 is formed by the wire 42, so that the ball runway 30 is more elastically bent than the strip plate material 32 of the above embodiment, and falls onto the ball runway 30. The game ball bounces or flows down while deflecting the ball runway 30, and the player is interested in the fun of the movement of the game ball. The driving means 31 of this embodiment is provided at the outer end 30 a of the wire 42. A shaft portion 43 bent substantially horizontally in a U shape is formed on the outer end 30 a of the wire 42, and is formed in the through hole 61 of the link member 34 through a guide hole 40 formed in the bottom of the concave chamber 27. The other end of the link member 34 is connected to the engaging pin 35 of the cam member 36 fixed to the motor shaft of the stepping motor 33, and the cam member 36 is rotated by the drive of the motor 33, via the link member 34. The inclination direction of the ball runway 30 is changed by moving the outer end 30a of the ball runway 30 up and down so that the flow direction of the game ball is changed. When the end of the ball runway 30 is always moved up and down, the electric drive source may be a normal inexpensive motor instead of a stepping motor capable of controlling rotation, and may be a solenoid.

  FIG. 8 shows another embodiment of the driving means. The driving means of this embodiment is provided with a rack 44 fixed to the outer end 30 a of the ball runway 30 slidably in the vertical direction on the side wall of the concave chamber 27, and a pinion 45 provided on the forward / reverse motor 46 on the rack 44. By engaging and driving the forward / reverse motor 46, the outer end 30a of the ball runway 30 is moved up and down to change the inclination direction of the ball runway 30 and to change the flow direction of the game ball. Also good. By adopting the configuration of the rack 44 and the pinion 45, the movement range in the vertical direction of the end of the ball runway 30 can be easily increased, so that the ball runway 30 can be made more three-dimensional. The inclination angle of the ball runway 30 changes depending on the magnitude of the change, and the flow velocity of the game ball can be changed. That is, if the height difference between the inner end 30b and the outer end 30a of the ball runway 30 is reduced, the game ball can slowly flow down the ball runway 30 inward or outward, and conversely the ball runway When the difference in height between the inner end 30b and the outer end 30a of the 30 is increased, the game ball flows down the ball runway 30 quickly. In this way, by changing the three-dimensional shape of the ball runway 30, the flow direction and the flow velocity of the game ball change, and the player is expected to win the specific winning area 25 and enhances the interest of the game. be able to.

  Further, the driving means does not necessarily tilt the ball runway 30 by driving the electric drive source, and the outer end 30a side is normally placed on the outer end 30a of the ball runway 30 as shown in FIGS. The seesaw material 47 that tilts downward may be pivotally supported on the bottom or side wall of the concave chamber 27 so as to be tiltable. One end of the seesaw material 47 is pivotally supported to the side of the outer end 30a of the ball runway 30, and a through hole 48 having a diameter smaller than the diameter of the game ball is formed at the other end as a storage portion for storing the game ball. . When the game ball falls from the ball receiving shelf 28 and the game ball fits into the through hole 48, the seesaw material 47 tilts, the outer end 30a of the ball runway 30 moves upward, and the ball runway 30 tilts. The direction can be changed, and the game ball can be directed to the inner end 30b by inward rotation and guided to the specific winning area 25. At this time, it is preferable to balance so that the seesaw material 47 tilts slowly by storing one game ball in the through hole 48. The game ball stored in the through hole 48 is detected by a sensor, and the solenoid 63 provided below the through hole 48 of the seesaw material 47 tilted after a predetermined time elapses to operate the game ball in the through hole 48 downward. The seesaw material 47 pushed out from the game ball and released from the load of the game ball is tilted back, the outer end 30a of the ball runway 30 is moved downward, and the game ball is rotated outwardly toward the outer end 30a. It flows out toward 26.

  Note that the game ball received by the movable piece 18 is dropped from the ball receiving shelf 28 as a means for guiding the game ball to the game ball guiding device 29. However, the upper wall of the concave chamber 27 is attracted by the weight of the game ball. A plurality of magnets having force are arranged up to a position beyond the center of the ball runway 30 so that the N pole and the S pole alternate along the inclination direction, and are formed on the lower surface of the upper wall of the concave chamber 27. The game ball may be guided so that it can hang. In this way, the game ball received by the movable piece 18 hangs down the upper wall lower surface of the concave chamber 27 by the magnetic force of the magnet, moves to the rear of the concave chamber 27 in a suspended state, and is released from the magnetic force. It will fall and be received on the ball runway 30. By providing the magnet on the upper wall of the concave chamber 27 as described above, the game ball moves in a hanging state, and a unique movement that has never been seen can be shown to the player. In addition, by arranging a plurality of magnets so that N poles and S poles are alternately arranged, locations with strong magnetic force can be formed at regular intervals, so that the game ball is attracted to the magnetic force and has a step-like movement. It can move and become a more specific movement. The magnet may be an electromagnet, and the game ball can be dropped to an arbitrary position on the ball runway 30 by using the electromagnet.

  In the embodiment, the driving means 31 is provided at the outer end 30a of the ball runway 30, but may be provided at the inner end 30b of the ball runway 30 as shown in FIG. At this time, the outer end 30 a of the ball runway 30 is fixed to the shaft portion 19 projecting about 1 cm from the bottom of the concave chamber 27. In this embodiment, the same reference numerals are given to the same components as those shown in the above embodiments. The link member 34 is moved up and down by the engagement pin 35 provided eccentrically by driving the stepping motor 33 as an electric drive source and rotating the cam member 36, and the inner end 30b of the ball runway 30 is moved up and down. Let Then, by making the inner end 30b of the ball runway 30 higher or lower than the outer end 30a, the inclination direction of the ball runway 30 is changed to change the flow direction of the game ball, and the ball runway 30 The upper game ball can be guided to the specific winning area 25 or the general winning area 26. Further, each of the inner end 30b and the outer end 30a of the ball runway 30 may be provided with driving means for moving the end portion up and down. The runway 30 can be in a more complicated tilted state, and the player's interest can be enhanced by unexpected movement.

  12 and 13 show another embodiment in which driving means is provided at the inner end of the ball runway. This embodiment differs from the previous embodiment in that a ball entrance 49 is provided as a winning opening so as to be connected to the inner end 30b of the ball runway 30, and a passage portion 50 communicating with the ball entrance 49 is provided. is there. In this embodiment, a planar spiral ball runway 30 is formed by a strip plate material 32, and a ball inlet 49 is opened at the inner end 30b. A ball outlet 51 is formed on the end side of the passage portion 50. A guide piece 52 for guiding the game ball to the side is provided at the ball outlet 51. An engaging portion 54 having a horizontally long hole 53 is formed at the lower end of the passage portion 50, and a clamp-like cam 55 fixed to the shaft of the motor 64 is connected. Further, an insertion piece 56 bent in an L shape is formed on the outer end 30 a of the ball runway 30, and is inserted into an insertion portion 57 formed on the bottom of the concave chamber 27 to fix the outer end 30 a. I am doing so. The game ball guidance device 29 configured as described above is mounted so as to be sandwiched between base bodies 58a and 58b which are divided into front and rear parts. The base bodies 58a and 58b are formed with a half groove that sandwiches the cylindrical passage portion 50 and a sliding groove 59 in which the engaging portion 54 slides, and the rear base body 58b includes A ball passage communicating with the ball outlet 51 is formed and a ball detection sensor is provided. Further, the front base body 58a is formed with a housing portion for the motor 64, and a guide portion for allowing the game ball to flow out to a predetermined position is formed in a concave groove shape at the front end portion of the upper surface.

  In the game ball guiding device 29 configured as described above, the motor 64 is always driven to move the inner end 30b of the ball runway 30 up and down as in the above-described embodiment, and the inner end 30b becomes the outer end 30a. A higher position or a lower position is set. When the game ball guided to the concave chamber 27 by the opening / closing timing of the movable piece 18 is guided to the inner end 30b of the ball runway 30 and wins the ball entrance 49, it becomes a “big hit”, and the movable piece 18 continues. Open and close. At this time, if the motor 64 is stopped in a state where the inner end 30b of the ball runway 30 is moved downward, the overall shape of the ball runway 30 is formed into a mortar shape that is easy to receive a game ball as shown by a solid line in FIG. Good. When a predetermined number of game balls enter the ball entrance 49 and are guided to the ball passage 65 and detected by the ball detection sensor 66, the motor 64 is once driven to move the inner end 30b of the ball runway 30 upward. Then, the motor 64 is immediately driven to move the inner end 30b downward to receive the game ball, and the predetermined number of rounds may be repeated. A game ball that has not won the ball entrance 49, such as a game ball received by the ball runway 30 at a position where the inner end 30b is moved up or a ball dropped from the ball runway 30, is a front base body. It is discharged from the front end of 58a onto the game board 3 surface.

  Next, an embodiment in which the game ball guiding device 29 is provided in the winning device A will be described. As shown in FIG. 11, the game ball guiding device 29 of this embodiment is provided with a ball entrance 49 serving as a winning opening so as to be continuous with the inner end 30b of the ball runway 30, and the outer end 30a is shown in FIGS. Driving means 31 indicated by 4 is provided. For this reason, detailed description of the drive means 31 is abbreviate | omitted. As shown in FIG. 14, the game board 3 is provided with a fluctuation display section 60 that variably displays symbols such as characters and a tulip type start winning opening 62 that fluctuates the fluctuation display section 60. Then, when the game ball wins the start winning opening 62 and is detected by the detection sensor 62a, the display of the fluctuation display section 60 is fluctuated. When the symbols of the fluctuation display section 60 are aligned with, for example, “777”, the “big hit” is obtained. The opening / closing operation is continued until a predetermined number of movable pieces 18 are won at the ball entrance 49 for a predetermined time. At this time, the ball runway 30 is in a state in which the outer end 30 a is moved upward by the driving means 31 to be inclined inward, and the game ball is guided toward the ball inlet 49. Then, the game ball received by the movable piece 18 is guided to the ball runway 30 from the ball receiving shelf 28 and flows down toward the inner end 30b while turning inward, and falls to the ball inlet 49. It flows out from the outlet 51 and is counted by the detection sensor 66. When a predetermined number (for example, 10) of winning balls is counted, the movable piece 18 is closed and the stepping motor 33 is driven to move the outer end 30 a of the ball runway 30 downward. By not winning, it is possible to prevent excessive winnings. At this time, even if a game ball is on the ball runway 30, the stepping motor 33 is driven to change the inclination direction of the ball runway 30, so that the game ball flows down toward the outer end 30a and is recessed. It is discharged from the chamber 27 to the game board 3 surface. Then, the game ball guided to the concave guiding portion 67 in a timely manner flows out toward the start winning opening 62. As described above, since the game ball is not only received by the open door plate like the conventional grand prize opening, the player goes through the ball runway 30 while turning the game ball and is guided to the ball entrance 49. Can enjoy.

  Further, as a method of using the game ball guiding device 29, it may be used as a distribution device that changes the winning probability to the start winning port 62, and the game ball guiding device 29 is provided above the start winning port 62. The game ball flowing out from the inner end 30b of the ball runway 30 is provided at a position where it flows down toward the start winning opening 62, and the drive means is driven in a normal state so that the ball runway 30 is tilted. By doing so, the game ball guided to the ball runway 30 is released from the outer end 30a of the ball runway 30 and flows down on the surface of the game board 3, or the inner end 30b of the ball runway 30. It is discharged from the vehicle and flows down toward the start winning opening 62 and wins the starting winning opening 62 with a high probability. In addition, the symbols of the fluctuation display unit 60 are aligned to become “big hit”, and after this “big hit” is finished, the so-called “probability fluctuation” state in which the next hit is certain or the fluctuation display unit 60 fluctuates a predetermined number of times (for example, 100 times). In the case of a so-called “time reduction” state in which the probability of a big hit is high during the period, the time for positioning the inner end 30b of the ball runway 30 below the outer end 30a is lengthened to win the start winning opening 62. It is preferable to increase the probability. With this configuration, it is possible to enjoy the flow-down mode of the game ball while increasing the winning probability to the start winning opening 62. Then, after the “big hit” or after the “time reduction” is completed, the driving source may be driven as in the beginning so that the inclination direction of the ball runway 30 is always changed.

  In the embodiment, the spherical runway 30 has a circular spiral that gradually increases in diameter from the inside toward the outside in plan view, but the ball runway 30 is long even if it is elliptical in plan view. There is no problem with the circular shape, and the flow velocity of the game ball changes at a gentle arc or straight line, which can change the movement of the game ball. Shows interest.
