Title:
揺れ補正機能付きアンテナ装置
Document Type and Number:
Japanese Patent JP6942572
Kind Code:
B2
Abstract:
The invention provides a small and inexpensive antenna device with a wobble correction function that can control the attitude of the antenna according to the swing. The antenna device is provided witha swinging support mechanism that supports the movable member on the fixing member and that swings the movable member freely around the swinging fulcrum on the central axis of the antenna; and a swinging drive mechanism enabling the movable member to swing based on a detecting result of a posture detecting sensor of the antenna, and a connection mechanism for connecting a driven part moving alonga direction crossing a central axis and a part of the support part of the antenna away from the swinging post through the swinging drive mechanism and allowing the relative shift of the different based on the movement direction. The swinging drive mechanism is provided with at least two actuators so as to enable the driven part to move along different directions crossing the central axis. Each actuator and the driven member are configured as that a connection part connected with one actuator, when being driven by another actuator, can move a movement direction of a driven part moving due to driving of the actuator.
