Abstract
PURPOSE: To secure the steady operation of the remote-control apparatus for a long time by controlling the power supply to the power motor by the internal resistance of the power source part and via the switching transistor in accordance with the power consumption of the power motor.
CONSTITUTION: The power is supplied to reception part 12 and control part 16 from power source part 30 via stabilizing circuit 31, and capacitor C1 is connected in parallel to part 30 via diode D1 to secure charging for the load of part 30. In this case, the power supply is reduced to power motor 21 by switching transistor TrQ1 when the voltage between the both terminals of C1 lowers down to the fixed level, thus C1 being charged. At the same time, the power supply to motor 21 is reduced properly by switching transistor TrQ2 and according to the power consumption of motor 21 as well as the internal resistance of part 30 when the power is supplied simultaneously to both motor 21 and the servo motor. Thus the power is supplied to motor 22 in preference for a fixed time. In this way, the steady operation can be secured for a long time for the remote-control apparatus.
