Abstract

To solve the problem in which a charger capable of charging a wireless primer detonator in low electric power has been needed conventionally.SOLUTION: A charger 50 has a power transmission coil 51 supplying power to a power receiving coil 12 of a primer detonator 10 wirelessly. A transmission antenna 51 transmitting a signal to the primer detonator 10 wirelessly is provided. A receiving antenna 51 receiving an identification signal from the primer detonator 10 wirelessly is provided. A control circuit 53 transmitting the identification signal is provided. An attachment part 50a attached to an explosive loading machine 30 loading an explosive 2 connected to the primer detonator 10 and the primer detonator 10 into a loading hole 5 is provided. The attachment part 50a is attached to the primer detonator 30 so that the charger 50 is integrally attached to the explosive loading machine 30. The control circuit 53 transmits the identification signal to a controller 34 of the explosive loading machine 30. Thereby, the controller 34 can associate the identification signal with loading hole information regarding the loading hole 5.SELECTED DRAWING: Figure 2
