Abstract

According to Fig. 1, a print head movable in line direction H (forward) with electrodes El to E5 arranged on a slope generates in position I a corresponding print. At the end of the line, the head - without there having to be a paper advance - is rotated from position I to position II in order to produce a corresponding print during line return R. Fig. 2 shows details of the rotating device. Print head 1 is guided by two guide rods 2 and 3. It moves via a continuous cable line (not shown). The assumed slope with the electrodes is provided on a disk 10 rotatable around axis A. For convenience of illustration, positions I and II (see, also, Fig. 1) of this slope are indicated by a line only. Also provided on the print head is a disk 20 rotatable round axis B. In its upper part 21, it is positively connected to disk 10.

Rotating Device for Bidirectional Writing Print Heads of Metal Paper Printers With Electrodes Arranged on a Slope

According to Fig. 1, a print head movable in line direction H (forward) with electrodes El to E5 arranged on a slope generates in position I a corresponding print. At the end of the line, the head - without there having to be a paper advance - is rotated from position I to position II in order to produce a corresponding print during line return R. Fig. 2 shows details of the rotating device. Print head 1 is guided by two guide rods 2 and 3. It moves via a continuous cable line (not shown). The assumed slope with the electrodes is provided on a disk 10 rotatable around axis A. For convenience of illustration, positions I and II (see, also, Fig. 1) of this slope are indicated by a line only. Also provided on the print head is a disk 20 rotatable round axis B. In its upper part 21, it is positively connected to disk 10. Behind disk 20, two angle brackets 22 and 23, having two arms each, are rotatably supported on axis B. At the outer end of the lower angle arms, pressure rollers 26, 27 are arranged in front of disk 20 which, by springs 24 and 25, respectively, are pushed onto a guide rail 28. At the end of the line, the guiding plane rises in part 28E. As soon as the print head reaches this area in arrow direction H, disk 20 rotates in direction C: roller 26, which has mounted slope 28E, effects a partial disk rotation which is made possible by the fact...
