ABSTRACT:
Printing members comprising a mosaic printing head are driven by flexural bending elements which are electrically actuated to produce a desired printed pattern. The bending elements may take the form of piezoelectric strips or diaphragm pieces which are supported by bearings located at nodal oscillation points of the elements. The printing members when actuated protrude from a bore in one end of a printing head housing. The printing head housing is mounted for transverse movement along guide rails.
