ABSTRACT:
In a serial recording apparatus wherein a recording head is carried on a carriage movable in the direction of a print column and the recording head is driven on the basis of printing data while scanning by the recording head, to thereby form a dot image on a sheet, piezoelectric elements are joined to a vibration plate provided on the underside of the carriage and the vibration plate is slidably urged against the surface of a fixed member by a resilient force to thereby constitute a travelling wave type ultrasonic motor. A travelling wave is generated in the vibration plate by the piezoelectric elements being driven to thereby control the movement of the carriage.
