Claims

[Scope of utility model registration request]

The antenna element group which is to be expanded and retracted in a multi-stage manner is expanded and retracted by a motor in a motor mechanism section, which causes a rotor wound with an expansion and contraction operation wire connected to the antenna element layer to be rotated forward or reversed, and the antenna element group to be expanded and contracted in a multi-stage manner. An interlocking relay switch that interlocks with a receiving state switching operation section provided in the receiving mechanism is provided in the motor circuit for the motor to start the motor, and the motor is set at 180 degrees with respect to its rotor when the brushes are opposed to each other. A two-brush type motor is provided, and an extension degree selection section for switching between full extension and contraction is provided in a circuit leading from the interlocking relay switch to one brush of the motor, and the extension degree selection section is provided. A 1-circuit 3-contact type switch is incorporated in the circuit from the motor i to the motor i to stop the rotation of the motor with the antenna half-extended, and the other brush of the motor is switched between forward and reverse rotation by relay operation. A cam rotating body linked to the rotor is provided in the antenna operating section, and the cam rotating body opens and closes a full extension limit switch and a storage limit switch provided in the monitor circuit. An antenna automatic expansion/contraction operation mechanism, characterized in that a cam-shaped operation section for opening and closing the one-circuit, three-contact type switch is formed together with the operation section.
