駆動制御装置。[Claims for Utility Model Registration] (1) A motor that is supplied with a DC power supply of a predetermined polarity and rotates forward or backward, and means that uses the rotational force of the motor to extend or contract a telescoping antenna element. , a displacement body provided to be displaced as the telescopic antenna element is extended or contracted by this means, and the displacement body is displaced to a position corresponding to the extension completion position or contraction completion position of the antenna element. and a switching circuit that cuts off the power supply to the motor in accordance with the ON or OFF operation of the magnetically sensitive element. Electric telescopic antenna drive control device. (2) In the device according to claim 1, the magnetically sensitive element is composed of a Hall element or a reed switch, and is set to be in an ON state at all times, and is turned OFF when the set state is released by the displacement body that has been displaced to a predetermined position. The electric telescoping device is operable, and the switching circuit is composed of a circuit including a Darlington connection circuit of transistors, and is configured to turn off when the magnetically sensitive element turns off. Antenna drive control device.
