Zusammenfassung:PURPOSE: It is provided with the input voltage to the fixed detonation current valence radical percussion fuse. The detonation point of time of the electrical type detonating cap regularly maintains. CONSTITUTION: A firing device comprises a current generating part(120), a control CPU(130), and a relay circuit part(110). An input voltage(A1) is provided to the current generating part. A Zener diode(121) and a transistor(122) of the current generating part are created the constant current with the input voltage. The control CPU controls the making current of the current generating part with a detonation signal(A3). The detonating cap is detonated after charge. The relay circuit part receives a message a charge signal(A2). The relay circuit part is switched in order to conduct the detonating cap and current generating part.
