Abstract

PURPOSE:To provide a follower of a directive receiving antenna, which can accomplish orientation promptly and reliably by properly trapping the elastic waves such as optical waves, electric waves or sound waves, which are generated by a transmitter, with the use of a simple device or an electric circuit. CONSTITUTION:A plurality of shielding cylinders 3, which are equipped with sensors for optical waves, electric waves and sound waves, are fixed to the upper end of a stand 9, which has its lower end rotatably supported on a base 8, with their openings 1 directed to the outside, such that elastic waves P coming at any angle from the above pass through any of the openings 1. If the electric circuits of the respective sensors are connected, the elastic waves P enter the most any of the openings 1 to exert their actions upon the sensors. Then, in accordance with the characteristics of the receiving elements of the respective sensors, a motor is turned forward and backward by the electirc automatic control so that the shielding members 3 are allowed to freely act about the lower end of the table 9. When the energy of the elastic waves P are sensed in an average by the sensors in the cylinders 3, the motor is interrupted.
