Title:
REMOTE CONTROL SIGNAL TRANSMITTER
Document Type and Number:
Japanese Patent JP2627594
Kind Code:
B2
Abstract:
PURPOSE: To operate a remote control receiver with a voltage of +VD superimposed on a signal of a transmission line.
CONSTITUTION: When a signal output section 22 generates an H level output signal, a transistor(TR) 5 is turned on and a TR 6 is turned off and a +VD is kept for a potential on a transmission line 39. Simultaneously a diode 7 is made conductive, the signal output section 22 is operated by the voltage +VD superimposed on a signal on the transmission line 39 and a storage battery 21 is charged. When the signal output section 22 generates an output signal of an L level, since the TR 5 is turned off and the TR 6 is turned on, the potential of the transmission line 39 reaches the ground potential. In this case, a diode 7 is nonconductive and the signal output section 22 is activated by a voltage from the storage battery 21.
