ELECTROGRAPHY ; ELECTROPHOTOGRAPHY ; MAGNETOGRAPHY ( information storage based on relative movement between record carrier and transducer G11B; static stores with means for writing-in or reading-out information G11C; recording of television signals H04N 5/76 )
NOTE
-
This subclass covers:

- the production of permanent directly-visible pictures in
conformity with an original picture or document, using an
intermediate imagewise distribution of an electric or
magnetic quantity, such as a charge pattern, an electric
conductivity pattern, or a magnetic pattern;
- the production of permanent directly-visible pictures
using an intermediate imagewise distribution of an
electric or magnetic quantity, when the origin and the
way of generating said intermediate distribution are not
relevant.

This subclass does not cover:

- use of electric signals for the transmission of the
picture information from the original to the reproduction,
i.e. pictorial communication, which is covered by subclass
H04N;
- production of pictures by heat patterns exclusively, not
using an electrostatic or magnetic pattern, which is
covered by group B41M 5/00 ;
- production of prints by transferring ink from a printing
form to a printing surface, without physical contact and
using the force of an electrostatic field, which is
covered by subclass B41M;
- selective printing mechanisms characterised by the
selective supply of electric current, or the selective
application of magnetism or radiation, to a printing
material or impression-transfer material, which are
covered by groups B41J 2/385 , B41J 2/435 .
