摘要

PROBLEM TO BE SOLVED: To provide a radio primer detonator unit that can much more reduce working hours in a vicinity of a cutting edge, a master die, a radio denotation system, and a radio denotation method.;SOLUTION: In a radio primer detonator unit 10, which includes a denotation part 10A, a control part 10B that is connected with the denotation part and ignites the same, and an antenna part 10C having a detonation part side antenna 30 in which the control part is an antenna uses by radio communication and a conductive wire 31 whose one end is connected with the control part and the other end to the detonation part side antenna, the control part 10B receives a transmission signal whose operation frequency is 100 KHz or more and 500 KHz or less via the detonation part side antenna 30 and conductive wire 31. The detonation part side antenna 30 has a loop form whose diameter is 30 cm or less.;COPYRIGHT: (C)2013,JPO&INPIT
