Abstract

Print head 1 is guided by two guiding rods 2 and 3. Its electrodes 4 produce a corresponding print during the forward movement in direction H. When the end of the line is reached, the electrode part of the head pivots by 2a, and the head prints subsequently during the return movement in direction R. It is only then that there follows a two-line paper transport, and the above described process is repeated. Electrode part 5 of head 1 is fixedly connected to a shaft 6 extending through carriage 7. At that end of shaft 6 which is away from electrode part 5, a pivotal lever 8 is provided having a coupling pin 9 arranged at its end. Coupling pin 9 engages in an element 10 attached to a continuous rotating belt 11. This belt moves over two circulation rollers (not shown).

Device for the Forward and Backward Movement of Bidirectionally Writing Print Heads of Metal Paper Printers With Electrodes Arranged on a Slope

Print head 1 is guided by two guiding rods 2 and 3. Its electrodes 4 produce a corresponding print during the forward movement in direction H. When the end of the line is reached, the electrode part of the head pivots by 2a, and the head prints subsequently during the return movement in direction R. It is only then that there follows a two-line paper transport, and the above described process is repeated. Electrode part 5 of head 1 is fixedly connected to a shaft 6 extending through carriage 7. At that end of shaft 6 which is away from electrode part 5, a pivotal lever 8 is provided having a coupling pin 9 arranged at its end. Coupling pin 9 engages in an element 10 attached to a continuous rotating belt 11. This belt moves over two circulation rollers (not shown). (For convenience of illustration, construction details excluding a mutual obstruction of element 10 and the circulation rollers are not shown.) Distance d between the belt paths is to be maintained by a corresponding support to ensure an equal angle position a of lever 8 during the forward movement in direction H, and the backward movement in direction R. During the forward movement, print head 1 is pulled (Z) by element 10, and pushed (S) during the backward movement.
