ABSTRACT:
A device for graphic recording, using a plurality of stacked electrode blocks. The electrode tip projects from the block obliquely with respect to the transport direction of the paper. Each block has an internal opening communicating with the others, so that one channel which extends through the entire stack of blocks is produced. Compressed air can be blown through this opening to scavenge paper particles.
