MATRISSKRIVARE MED AUTOMATISK REGLERING AV TRYCKHUVUDET

摘要

A matrix printer with a printing head which is displaceable along a paper guide in the line direction and which has a number of printing elements which have a first printing position for printing from left to right and a second printing position for printing from right to left. The printing head with its printing elements is automatically moved from the one printing position to the other printing position by variation of the impulse of movement of the printing head upon each movement reversal of the printing head by means of a position changer which is displaceable with respect to the printing head.
