Abstract
A mounting bed integral with a hammer bank is disposed parallel to a counter balancer composed of a counter balancer constituting member and a yoke. The mounting bed and the yoke are provided with solenoid coils opposed to a permanent magnet provided on the frame, and a pair of bearings are arranged between the mounting bed and the counter balancer constituting member. A position sensor for the mounting bed and the counter balancer is provided. A controller is provided to control a current and direction of the solenoid coil by a detection signal from the position sensor. The mounting bed integral with the hammer bank and the counter balancer are shuttle-operated in opposite directions by the controller.
