Abstract

A scanning test head is provided which maintains a constant speed over the scanning path with the constancy of the speed in the scanning zone being dependent solely on the drive motor characteristics. An endless belt received on a pair of spaced rollers carries a pin which, on being driven around the closed path, serves to define the head scanning path.
