Title:
ROTATIONAL MOTION MECHANISM
Document Type and Number:
WIPO Patent Application WO/1996/032223
Kind Code:
A1
Abstract:
A rotational motion mechanism capable of securely controlling the rotational angle of a rotational body with high accuracy and effecting miniaturization of a device. In this mechanism, a moving body is able to move in a two-dimensional plane. A driving means moves the moving body. A circumferential bearing is formed into a circularly annular shape and is provided in a plane that is parallel to the two-dimensional plane. The rotational body is carried by the circumferential bearing and is able to rotate on its axis. A guide portion is provided at least on one side of the rotational body and radially relative to the axis of the rotational body. A conecting member is provided on the moving body for rotation on an axis parallel to the axis of the rotational body, and is connected to the guide portion in such a manner as to move longitudinally of the guide portion to rotate the rotational body via the guide portion as the moving body moves.
