ABSTRACT:
For typewriters, disk printers or similar moveable print element devices, a carrier is provided to move the print element. The carrier acts by cooperation between a lead screw, mounted in stationary supports in a nonrotating fixture, and rotatable nut members supported in the print element carrier and threadedly engaging the lead screw. A motor is provided for rotating the nuts and the motor is arranged so that the rotor of the motor, the nuts and the lead screw are arranged in concentric fashion so that the motor, nuts and carrier assembly ride back and forth on the fixed lead screw, depending upon the direction of rotation of the motor.
