The positional relationship among the fixed rack gear 36, the arm 85, the pinion gears 52, 54, and 56, and the movable rack gear 75 is configured as shown in FIG. That is, when the motor 81 rotates in the forward and reverse directions, the pin 83a of the rotating member 83 reciprocates in the elongated hole 85c of the arm 85, so that the arm 85 swings about the shaft support portion 85b and the first not shown in FIG. The elevating member 50 is moved up and down. At this time, the first pinion gear 52 rotatably supported by the first elevating member 50 moves up and down along the fixed side rack gear 36 fixed to the base member, thereby starting rotation. The rotation of the first pinion gear 52 is sequentially transmitted to the second pinion gear 54 and the third pinion gear 56. Since the second elevating member 70 supported by the first elevating member 50 so as to move up and down is provided with a movable rack gear 75, the second elevating member 70 is moved forward and backward by the third pinion gear 56. Can move up and down with respect to the first elevating member 50.

4 (a), 5 (a), 7 (a), and 9 (a) show the most elevated state of the telescopic mechanism, and the inner end of the arm 85 when the decorative body 31 is in the raised position. The (shaft support portion 85a) is positioned above the outer end portion (shaft support portion 85b), and the inner end edge (left end portion in front view) of the elongated hole 85c is more than the outer end edge (right end portion in front view). Located above. Further, the pin 83a is located near the outer edge of the elongated hole 85c, and the pin at this time is located on the outer side (right side) of the rotation center of the rotation member 83. In this state, since the pin and the elongated hole are in a locked state, even if the motor 81 is stopped, the entire lifting mechanism 40 is not lowered by the weight of the decorative body 31 and the expansion / contraction mechanism 45.
Next, FIG. 4 (b), FIG. 5 (b), FIG. 6 (c), FIG. 7 (b), FIG. 8 (c), FIG. 9 (b), and FIG. When the motor 81 stopped at the highest position starts to rotate in the downward direction, the pin 83a starts to move inward (left side) in the elongated hole. The arm starts to swing downward about the shaft support portion 85b, and the first elevating member 50 is lowered. For this reason, the first pinion gear 52 is rotated by the fixed rack gear 36, and this rotational force is sequentially transmitted to the second and third pinion gears 54 and 56. Since the rotation of the third pinion gear 56 is transmitted to the movable rack gear 75, the second elevating member 70 also starts to descend.

6 (d), 8 (d), and 10 (d) show the lowest state, and the distance between the first and second elevating members 50 and 70 with respect to the base member 35 is maximum. .
As shown in FIG. 11, the first elevating member 50 is lowered to a position where the first pinion gear 52 can be lowered to the maximum along the fixed rack gear 36, and the second elevating member 70 is provided with the second pinion gear. 56 descends to a position where it can descend to the maximum along the movable rack gear 75, the maximum lifting distance of the decorative body 31 fixed to the second lifting member 70 further exceeds the lifting distance of the first lifting member alone. Distance.

As described above, in the decorative body unit of the present invention, the vertical width of the expansion / contraction mechanism 45 is minimized when the decorative body 31 is raised, while the vertical mechanism is maximized when the decorative body is lowered. . In addition, since the first and second elevating members 50 and 70 are expanded and contracted in two stages with respect to the base member, the expansion / contraction mechanism is configured so that the vertical width when the expansion / contraction mechanism is extended is equal to the vertical width when the expansion / contraction mechanism is shortened. Can be more than doubled. For this reason, in the limited space called a game board surface, the extension distance of a decoration body unit can be ensured as much as possible, a presentation effect can be heightened, and the variation of game contents can be expanded.
Further, the decorative body unit is composed of a thin base member 35, first and second elevating members 50, 70, and a thin wall disposed in a compact manner on the back and front surfaces of the first elevating member. Since it is only composed of the gear groups 52, 54, 56 and the motor 81 or the like partially projecting rearward from the back surface of the base member 35, the front and rear direction dimension (thickness) of the decoration unit is made thin. The mounting space with respect to can be reduced.
Although the detailed configuration of the pachinko gaming machine is not illustrated and described, there is no doubt that the technical scope of the present invention includes a pachinko gaming machine and a game board unit (game board + decorative body unit). .
