Title:
SIGNAL TRANSMITTER
Document Type and Number:
Japanese Patent JP3534458
Kind Code:
B2
Abstract:
PURPOSE: To prevent a voltage drop disadvantageous for a signal level generated in an electronic switch by providing a means which can obtain a signal that interrupts the receiving operation of a transmitter-receiver in transmitting signals from signals received by a transmitter-receiver during receiving operation.
CONSTITUTION: In the route of a signal transmission line 3 between transmitter- receivers 1 and 2, a common conduction interrupter 4 is provided. A signal transmitter is also provided with other transmitter-receivers 5 and 6, and, for example, the transmitters-receivers 5 and 6 are interposed where the transmitter- receiver 2 operates as a transmitter and the transmitter-receiver 1 operates as a receiver. A received signal generated from the transmitting signals of the transmitter-receiver 6 is outputted to the output terminal of an AND gate 8 of an electronic control section 7, and introduced to the receiving input terminal 12 of the transmitter-receiver 5. The output signal reaches the input terminal of another AND gate 9 and interrupts the gate 9. Therefore, no signal is outputted to the output terminal of the gate 9 and the feedback action to the transmitter-receiver 6 is inhibited. Thus a voltage drop disadvantageous for the signal level generated in an electronic switch is prevented.
