Title:
CONTROL CIRCUIT FOR RADIO CONTROL
Document Type and Number:
Japanese Patent JP3882662
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control circuit for radio control that can be used easily, without misoperations or wasteful power consumption, even though it has a simple construction of a single switch for two power sources.
SOLUTION: The circuit has a receiver 1 that generates control signals based on signals from the transmitter, a servo 8 controlled by the control signals, a controller 2 that receives the control signals, a motor 3 that is controlled by the controller, a first power supply 4, a switch 21 connecting the first power supply to the receiver and the motor, a second power supply 7, and a power supply unit 20 connected to the receiver, the controller, and the second power supply. The power supply unit 20 operates when a control signal is sent from the receiver, which has become operable through a switching operation, compares the first power supply and the second power supply and provides the higher power supply voltage to the receiver, the controller, and the servo. The unit maneuvered can continue to be maneuvered, without problems, even if one of the power supplies runs low by switching to the auxiliary power supply, so that it can be safely recovered without causing any accident.
