Abstract
In a vibration frame (1) for print elements (2) of a matrix line printer, the print elements (2) are furnished in the clapper armature construction. The print elements (2) form neighboring component units in line direction (3) in or, respectively, at a profile rod (7). Said component units include, in each case, a magnetic yoke (8), an electromagnetic coil (9), a clapper armature (10), a clapper armature pivoting hinge support (11), a restoring spring (12), and print elements (2) attached at the clapper armature (10). In order to create a space-saving lateral guiding for the clapper armature (10), the clapper armature (10) is, in each case, laterally guided and pivotably movable by at least one tongue (15), extending perpendicular to the longitudinal extension and engaging into a recess (16). The restoring spring (12) is formed as an arm spring (17). The arm spring (17) forms with a spring arm (18) a second lateral guide for the clapper armature (10).
