ABSTRACT:
A character applying device which is controlled by a separate signal processor can be manually moved across a writing surface while the characters are being applied. A single-tipped marking instrument is moved with a prescribed motion parallel to the surface as the device is moved across the surface to create a relatively dense array of line patterns. Simultaneously, received control signals cause the tip to move in and out of contact with the surface for, in effect, masking the array to produce characters represented by those signals.
