Device for parallel justification of print head carriage guides relative to the platen in a printer, particularly in a matrix printer

摘要

In such a device with a platen (6), the print head carriage guide consists of a carriage guide shaft (5) at the rear of the printer frame (1), which is capable of being positioned parallel to the platen (6), and a front carriage guide shaft (4) opposite the platen (6) and positioned at a minimum separation distance, where each of the front and rear carriage guide shafts (4,5) is mounted in the side panels (2,3) of the printer frame (1) and the platen (6) is arranged at a different height to the front carriage guide shaft (4). …??In order to find a solution which is simple and operates precisely and which is based upon settable and measurable increments, it is proposed that the rear carriage guide shaft (5) is mounted in the side panels (2, 3) by means of cams (13) and the parallel justification between platen (6) and print head carriage guide can be accomplished by raising or lowering one side of the rear carriage guide shaft (5). …IMAGE…
