Abstract
An oscillatory driving mechanism for use with a scanning transducer includes a configured magnet structure having an associated torque coil cooperating therewith. The torque coil is mounted on a pivoting armature which, in turn, carries the scanning transducer through the predetermined arcuate path. A split pole piece magnetic structure is also positioned adjacent the armature. The armature carries a permanent magnet into an adjustable position relative to the split pole piece members. Hall plate sensors are positioned with respect to the pole piece members to detect the position of the armature at any instant.
