[Problem] To wire a perforating machine lead wire such that the load thereon is reduced without externally exposing a curved section. [Solution] A lead wire (50) connects a drive control circuit (12) inside of the main body (20) of this perforating machine (10) and a motor (36) inside of a perforating drive unit (30), and this lead wire is made to extend from the motor, pass through a lead wire insertion path (60) between the main body and the perforating drive unit and to continue downwards in a lead wire housing unit (70) inside of the main body; then, in the lead wire housing unit, the lead wire is then made to curve to face upwards, and the upward-facing section (52) is held in a holding unit (84) and to reach the drive control circuit. By this means, when the perforating drive unit (30) is displaced upwards relative to the main body (20), the curved section (54) comprising the part of the lead wire (50) fed out from the lead wire housing unit (70) upwards into the lead wire insertion path (60) is displaced upwards inside of the lead wire housing unit, and when the perforating drive unit has been displaced downwards relative to the main body, the lead wire moves in the opposite manner. |
