Title:
REMOTE CONTROLLER
Document Type and Number:
Japanese Patent JPS5797115
Kind Code:
A
Abstract:
PURPOSE:To simplify the circuit constitution, by actuating alternately a transmitter part and a receiver part in a time shared wat at the side of operation and the side to be controlled and using an oscillating circuit part which produces the electric wave of transmission also for an oscillating circuit part at the receiver side to produce the local oscillation voltage. CONSTITUTION:The transmitted electric wave is received and demodulated at the side to be controlled to drive a part 34 to be operated in accordance with the control signal of the side of operation. Then the state of operation is received and demodulated at the side of operation in the form of a feedback signal, and the state of operation of the part 34 is monitored at the side of operation. Oscillating circuit parts 14 and 39 that produce the electric waves of transmission, output circuit parts 15 and 40 that transmit the outputs of the parts 14 and 39 in the form of the electric waves, receiver circuit parts 20 and 31 that receive the introduction of the output of oscillation in the form of the local oscillation voltage and receive and demodulate the received electric waves by a superheterodyne system, and transmission/reception changeover parts 19 and 37 that produce a signal to alternately switch the state between the transmission and reception are provided at the side of operation and the side to be operated respectively.
