<p><P>PROBLEM TO BE SOLVED: To provide a rotary display device of a game machine realizing the rotary drive of a rotary body rotated around two crossing axes by simple constitution. <P>SOLUTION: The rotary body 38 is supported rotatably around the axis H by a support arm 32 via a rotary shaft 40. The support arm 32 is supported rotatably around the axis V crossing the axis H by a bearing member 22 via a support arm rotary shaft 28 and is rotationally driven around the axis V by a stepping motor 50. Also, by providing the rotary shaft 40 with a bevel gear 46 and engaging it with the bevel gear 26 provided on the bearing member 22, the bevel gear 46 is rotated via the bevel gear 26 accompanying the rotation around the axis V of the rotary body 38 by the rotation of the support arm 32, and the rotary body 38 is rotated around the axis H. <P>COPYRIGHT: (C)2004,JPO</p> |
