The present dot printer comprises a suspension spring and frame element (1) constituted by two identical E-shaped plate spring elements (2, 3), having each a stile (10), and an upper (11), a central (12) and a lower (13) legs. A member (7) supporting the dot printing elements (22) is connected to the upper pair of legs (10) and positioned in front of and parallely to a platen (26). The central pair of legs (11) are connected to a frame piece (9) which is rigdly affixed to the printer frame. The upper and lower pairs of legs (10, 12) are connected together through a bar (6). Both stiles (10) of both E-shaped elements (2, 3) are also connected together. Driving means (14, 15, 16) connected to the free ends of both the upper and lower pairs of legs (10, 12), imparts a reciprocating motion, thereto, with a substantial linear velocity, in a direction parallel to a print line. The linear velocity is obtained either through electronic or mechanical means. |
