I try to let them.

  As shown in FIG. 3, when the effect member 90 is assembled, the overall appearance of the effect member 90 can be grasped when the outer periphery of the effect member 90 is hidden by the inner periphery of the decorative body 31. This is not possible and the decorativeness will be reduced. In addition, when the entire outer periphery of the effect member 90 is exposed, a gap is formed between the outer peripheral surface of the effect member 90 and the inner peripheral surface of the decorative body 31, and in this case also, the decorativeness is deteriorated. Become.

  In order to improve the decorativeness, the upper left portion of the effect member 90 is disposed so as to overlap the inner peripheral portion of the decorative body 31 in the front and rear, and a gap that allows the effect member 90 to swing is provided in the overlapping portion. Further, a semi-annular gap is formed between the outer peripheral surface A of the right half of the effect member 90 and the inner peripheral surface B of the decorative body 31, and the gap is shielded by the shielding member 110.

  As shown in FIGS. 4 and 15, the shielding member 110 has a curved portion 111 having a translucency in which the inner peripheral portion extends along the outer periphery of the effect member 90 and the outer peripheral portion overlaps with the inner peripheral portion of the decorative body 31 in the front-rear direction. The head portion 112 is shaped like a snake with an inward head portion 112 provided at one end thereof, and a plurality of attachment pieces 113 are formed on the outer periphery of the head portion 112. In addition, a substrate 114 is provided on the back side of the head 112 and has substantially the same shape as the head 112, and an upper end projecting above the head 112. The substrate 114 illuminates the head 112 from the inside. A light emitting diode 115 is mounted.

  The shielding member 110 is attached by screwing the upper portion of the attachment piece 113 and the substrate 114 covered by the decorative body 31 to the upper portion of the back cover 34. At this time, the head 112 as the fixed-side end portion is accommodated in the recess 93 of the effect member 90, the inner periphery of the bending portion 111 is along the outer periphery of the effect member 90, and the outer periphery of the bending portion 111 is the decorative body. 31. The effect member 90 can be swung between the inner periphery of the bending portion 111 and the outer periphery of the effect member 90 in the attached state. The interval is secured.

  By attaching the shielding member 110 as described above, the boundary between the effect member 90 and the decorative body 31 is eliminated, and the decorativeness of the pachinko machine can be improved.

  Here, since the upper part of the shielding member 110 is attached to the back cover 34 by screwing, the end of the curved part 111 approaches the effect member 90 due to deformation or bending of the attachment part due to a temperature change or the like. It is assumed that the swing of the effect member 90 is inhibited.

  In order to eliminate such problems, as shown in FIGS. 5, 8, and 9, on the front surface of the seat plate 66 provided in the casing 51, forward from the window 95 formed in the upper part of the effect member 90. A bar-like support member 67 that extends and has a tip surface that contacts or slightly contacts the back surface of the substrate 114 of the shielding member 110 is provided.

  As described above, by providing the support member 67 on the seat plate 66, it is possible to prevent the end portion of the curved portion 111 from approaching the effect member 90 due to deformation or deflection of the attachment portion of the shielding member 110, and the effect member. The space | interval which enables the production | generation member 90 to rock | fluctuate between 90 can always be ensured.

  Here, as shown in FIG. 3, the surface of the curved portion 111 of the shielding member 110 has a configuration in which the concavo-convex portion 116 is continuous in the length direction, while the effect member 90 has the surface as described above. Since the mirror surface is finished, the uneven portion 116 and the pattern portion 33 of the decorative body 31 are projected with distortion on the outer peripheral portion of the surface of the effect member 90. At this time, the effect member 90 is swung around the fulcrum shaft 92 by the swing driving device 100, and thus the projected image changes variously. Even when the swing amount of the effect member 90 is small, the effect member 90 is dynamic. You can give the impression that you are moving.

  As shown in FIG. 4, inside the back cover 34, a position facing the pattern portion 33 of the decorative body 31, a position facing the transparent portion 99 of the effect member 90, and a position facing the curved portion 111 of the shielding member 110. Each of the substrates 120 is provided with a light emitting diode 121 that illuminates the decorative body 31, the transparent portion 99, and the curved portion 111 from the inner surface side.

  The pachinko machine shown in the embodiment has the above structure, and an example of its operation will be described next.

  Now, when the game ball thrown into the game area 11 by the operation of the launch lever 9 shown in FIG. 1 falls and wins the start winning opening 16, the change in the symbol on the display panel 41 of the symbol display device 40 shown in FIG. 2. Display is performed.

  When a plurality of special symbols are stopped and displayed on the display panel 41 of the symbol display device 40, a special gaming state is generated, and the characters “right-handed” are displayed on the display panel 41.

  When the player hits the right according to the above display and the game ball passes through the second gate 18 or the first gate 15, the first grand prize opening 17 is opened with the passage of the gate as a trigger. When winning a prize, the second big prize opening 19 and the third big prize opening 20 are opened.

  When a predetermined number of game balls have won in the second grand prize opening 19 and the third big prize opening 20, or when the set time has elapsed, the second big prize opening 19 and the third big prize opening 20 The special game state is closed, and at the same time, the stepping motor 72 of the first gear drive mechanism 70 and the stepping motor 83 of the second gear drive mechanism 80 shown in FIG. 6 are started. Further, the swing drive device 100 shown in FIG.

  When the stepping motor 83 of the second gear drive mechanism 80 is started, the shielding reel 60 rotates, and when the opening 61 of the shielding reel 60 faces the opening 55 of the reel accommodating space 52, the stepping motor 83 stops.

  In addition, when the stepping motor 72 of the first gear drive mechanism 70 is started, the pair of display reels 56 are rotated, and the variation display of the symbol 58 is started. When the display reel 56 rotates, the effect driving member 100 repeatedly performs the swinging motion around the fulcrum shaft 92 by the operation of the swing driving device 100.

  The effect member 90 stops immediately before the display reel 56 rotates by a set angle or immediately before the stop, and when a plurality of special symbols are stopped and displayed on the display window 91 of the effect member 90, a big hit gaming state occurs. .

  When the game ball passes through the second gate 18 in the jackpot game state, the first grand prize opening 17 is opened as described above, and when the game ball wins the first big prize opening 17, the second grand prize is won. The mouth 19 and the third grand prize opening 20 are opened.

  When a predetermined number of game balls have won in the second grand prize opening 19 and the third big prize opening 20, or when the set time has elapsed, the second big prize opening 19 and the third big prize opening 20 Close.

  The opening of the first grand prize opening 17 by passing the game ball to the second gate 18 and the second big prize opening 19 and the third big prize opening 20 by winning the game ball to the first big prize opening 17 The opening is repeated for a preset number of times. When the set number of times is reached, the jackpot gaming state ends.

  When the big hit gaming state is finished, the shielding reel 60 is rotated by restarting the stepping motor 83 of the second gear drive mechanism 80, and the lid 62 of the shielding reel 60 faces the opening 55 of the reel accommodating space 52. The stepping motor 83 is stopped and the opening 55 is closed by the lid portion 62.

  As described above, the effect member 90 repeats the rocking motion when displaying the variation of the symbols due to the rotation of the pair of display reels 56 of the rotary display device 50, so that the player seems to be a big hit sign. As a result, the user has a sense of expectation, and the fun is doubled as compared with the case where the display reel 56 is simply rotated.

  Here, when the effect member 90 stops, the effect member 90 has a center of gravity located on the front side portion of the fulcrum shaft 92, and the effect member 90 swings in the direction in which the upper part moves forward due to the weight acting on the position of the center of gravity. As shown in FIGS. 5 and 8, the rib 98 at the lower end of the projecting portion 96 is supported on the upper surface of the seat plate 66.

  At this time, the effect member 90 is in a three-point support state in which the pair of fulcrum shafts 92 provided on both side surfaces and the protrusion 96 provided at the upper center of the back surface of the effect member 90 are supported. The member 90 stops stably and always stops in a constant and good state.

  As shown in the embodiment, when the gap formed between the inner peripheral surface of the frame-shaped decorative body 31 and the outer peripheral surface of the effect member 90 is shielded by the shielding member 110, the boundary between the effect member 90 and the decorative body 31 disappears. Moreover, since the shielding member 110 exhibits a decorative effect as a decoration, a pachinko machine having excellent decorativeness can be obtained.
