Title:
BISTABLE MOVING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/033851
Kind Code:
A1
Abstract:
A mover (1) is movable in a movable axis (Z-axis) direction and held so as to prevent rotation about the movable axis. The mover (1) is constituted by a first permanent magnet (1-1) and a second permanent magnet (1-2), and the magnetic poles of the permanent magnets (1-1, 1-2) are arranged so that different poles face each other in the movable axis direction. A ring-shaped permanent magnet is provided on the outside of the mover (1) as a rotor (4). The rotor (4) is rotatable about the movable axis and held so as to prevent movement in the movable axis direction. By rotating the rotor (4), an arrangement of the magnetic poles on the inner circumferential surface of the rotor (4) is changed between a first arrangement (S pole on the upper side, N pole on the lower side) and a second arrangement (N pole on the upper side, S pole on the lower side), so that the mover (1) is latched at movement positions on one side and the other side of the movable axis direction. This makes it possible to obtain a bistable moving device having a high safety and capable of obtaining a reliable operation.
