Pin printer head for a high definition dot matrix printer

摘要

The head has twenty four pins (11) each welded to the edge (56) of a blade (44) placed in a radial plane. Each blade (44) is rigidly attached to the keeper (41) of a corresponding electromagnet (25), which is placed in a plane perpendicular to that of the corresponding blade The edge (56) is supported by an appendage which can have two different forms (53 and 54) so that the edges (56) of successive blades (44) are radially offset so reducing the distance between these edges and the axis (16) of the head. Blades (44) normally rest against an elastomeric ring (63), the position of which can be adjusted along axis (16).
