ABSTRACT:
A linear motor for a printer has stator teeth which are protected from dust and debris generated when the printing mechanism strikes the recording paper by a downward extension of the stator teeth, by a horizontal extension of the stator teeth, or by a horizontal extension of stator teeth which face away from the printing platen. The translating member of the motor to which the printing mechanism is attached has pole teeth spaced from the stator by mechanical rollers. The motor force acts close to the center of gravity of the moving members to reduce mechanical vibrations.
