<p><P>PROBLEM TO BE SOLVED: To provide a device for detecting an obstacle which accurately detects the obstacle by improving a transmitting system of obstacle detecting information and further realizes cost reduction by reducing a working time for securing. <P>SOLUTION: In the device for detecting the obstacle which selectively drives leak electric wire paths 21 to 23 for transmitting within information transmitting means via a transmitting/receiving circuit, radiates electric wave in response to a signal for detecting from the leak electric wire path 21 to 23 for transmitting toward leak electric wire paths 31 to 33 for receiving, and obtains detected information transmitted via the transmitting/receiving circuit and the leak electric wire paths for transmitting, the transmitting/receiving circuit automatically carries out detecting of breaking of wire and securing of a transmitting path, by switching function of each leak transmitting path 21 to 23 for transmitting whose breaking of wire is detected to each leak transmitting path for receiving when the breaking of the wire of the leak electric wire paths 21 to 23 for transmitting which are connected to itself within the information transmitting means is detected. <P>COPYRIGHT: (C)2004,JPO</p> |
