PRINTING HEAD AND BRUSH CONFIGURATION FOR A MAGNETIC PRINTER

摘要

RD 9814 A magnetic printer includes an elongated comblike printing head disposed opposite a magnetizable-oxide-bearing surface of a selectively magnetizable moving belt. The printing head is adapted to magnetize regions of the belt in a direction transverse to the direction of belt movement. The magnetic printer also includes a magnetic brush for depositing magnetic ink upon the oxide-bearing remaining surface of the belt. The magnetic brush is positioned beneath the printing head, whereby the printing head provides a bearing surface along which the magnetic belt slides. The brush is designed for minimum field at the inking position, while the head is designed to have its field direction transverse to the direction of the field of the brush, for minimum field interaction.
