Title:
ACTIVE GUIDE ROLLER AND ELEVATOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/198197
Kind Code:
A1
Abstract:
In this active guide roller and elevator device, one among an actuator movable unit and an actuator fixed unit is provided with: a yoke that is configured in a closed magnetic path and that has a middle leg part and a pair of side leg parts disposed facing each other with the middle leg part interposed therebetween; and a pair of magnets that are respectively provided on the middle leg part-facing surfaces of the pair of side leg parts, and that generate magnetic fields that cross a rocking surface of a guide lever. The other among the actuator movable unit and the actuator fixed unit is provided with a bobbin that has a winding barrel part into which the middle leg part is inserted, and a coil wound around the winding barrel part and disposed inside the magnetic field. When the actuator movable part is displaced in a direction at a right angle to the rocking surface, the bobbin and the magnets or the bobbin and the yoke come into contact so that contact between the coil and the magnets can be avoided.
