Abstract
PURPOSE:To eliminate the burning of a motor and wasteful consumption of a power source by interrupting a power source circuit when a current flows in the motor even after the prescribed time corresponding to the prescribed operation amount is elapsed at the time of operating a control switch. CONSTITUTION:When a radio switch 19 is, in case that an ignition switch 2 is closed ON, closed ON, a transistor 7 is conducted, and a contact 8a is thus closed. Since the contact 15a is switched to the contact 15b simultaneously, an antenna motor 17 is forwardly rotated. On the other hand, an arithmetic amplifier 12 detects a motor current and hence charges a capacitor 14. When a limit switch 16 is not interrupted even after the prescribed time is elapsed, a transistor 6 is conducted ON, and the transistor 7 is interrupted OFF, and the contact 8a is opened. When a switch 2 or 19 is opened, the transistor 7 is conducted by the discharge current of the capacitor 4, and the antenna motor 17 is reversely rotated.
