Abstract

PURPOSE:To make possible high speed printing by a method wherein through the expansion of substantial magnetic path of a leaf spring, the attractive energy of a magnet is used efficiently for the attraction of the leaf spring, the spring constant of the leaf spring is enhanced and the natural frequency of the leaf spring is increased. CONSTITUTION:Into both sides of each leaf spring 16 are inserted lateral york 26 which is parallel to each leaf spring 16 with a small gap and alternately comblike to each leaf spring 16. The root of the lateral york fixes the root of each leaf spring between the root of the lateral york and a base 24. The magnetic flux 27 radiated from a permanent magnet 17 is divided into that for the leaf spring 16 and that for the lateral york 26 at the edges of the leaf springs 16. Accordingly, half the width of the leaf spring 16 may be sufficient for the thickness of the attractive part of the leaf spring, the mass thereof can be decreased, therefore the natural frequency of the leaf spring will increase substantially and a printer of high speed and excellent energyefficiency can be abtained.
