Abstract
An electrically conductive wire brush for use with a conductive-backed recording paper to conduct electrical energy to the conductive backing of the paper thereby heating it to develop an image, the brush making flexible contact with the paper substantially continuously throughout its width.
Claims7
Apparatus for use in a recorder having a moving conductive-backed paper to supply electrical energy to the conductive backing comprising:
- a wire brush for applying a uniform heating current to the paper, the brush including a sufficient number of wire bristles to contact the conductive backing in a substantially continuous fashion across the paper so that all portions of the paper proximate the brush are contacted, the wire bristles being fine enough to bend and make a flexible contact with the conductive backing;
- and
- means connecting the wire brush to a source of electrical energy.
