摘要

To provide a device capable of grasping the state of each head unit while discriminating between underground work machines in which the transmitting device is attached to the head units of a plurality of underground work machines that are enlarged drilling machines.SOLUTION: The present invention is a transmitting/receiving device 4 used for an enlarged drilling machine 2 performing an enlarged drilling operation. In the transmitting/receiving device 4 provided with a transmitting device 6 attached to an enlarged drilling head 30 and transmitting radio waves of a predetermined frequency to the ground when the enlarged drilling head 30 is in a slightly open state, a middle open state or a fully open state, and a receiving device 8 for receiving the radio wave and generating an output signal corresponding to each state of the enlarged drilling head 30. The transmitting device 6 is configured to signal the unique identification information possessed by the transmitting device 6 and place it on a radio wave for transmission. The receiving device 8 identifies the transmitting device 6 having the identification information based on the identification information of the transmitting device 6 obtained from the received signal, and outputs an output signal together with the signal representing the identified transmitting device 6.SELECTED DRAWING: Figure 1
