Abstract

PURPOSE:To make it possible to realize the driving system of each antenna by an independent servo mechanism by fitting the motor, which drives the upper side antenna, and a deceleractor to the same fitting base as the motor for driving the lower side antenna, etc. CONSTITUTION:Double-structure transmission path 2 is coupled with antennas 3 and 5 by couplers 4 and 6 respectively. Antenna 3 is fitted to rotary support material 8, and support material 8 is rotated freely while being stopped by servo-motor 10, output gear 12 of decelerator 11 and gear 9 which are fitted to base 1. Antenna 5 is fitted to rotary support material 14 supported by the bearing which is fitted to support material 8, and servo-motor 16 and decelerator 17 are fitted to base 1, and output gear 18 is stopped to gear 21. The rotation of motor 16 is propagated through gears 18, 21, 22, 25 and 15 to rotate antenna 5. Gears 22 and 15 have the same number of teeth. As a result, antenna 5 maintains a stop state in case that antenna 5 is stopped to rotate antenna 3. Similarly, antenna 3 maintains a stop state in case that antenna 3 is stopped to rotate antenna 5.
