G03
Note(s)
In this class, the following terms are used with the meaning indicated:
"records" means photographs or any other kind of latent, directly-visible or permanent storage of pictorial information, which consist of an imagewise distribution of a quantity, e.g. an electric charge pattern, recorded on a carrier member;
"optical" applies not only to visible light but also to ultra-violet or infra-red radiations.
This subclass covers the production of permanent directly-visible pictures in conformity with an original picture or document, using an imagewise distribution of an electric or magnetic quantity, such as a charge pattern, an electric conductivity pattern, or a magnetic pattern.
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 Fulltext... Hierarchy... Expanded...H04N;
production of pictures by heat patterns exclusively, not using an electrostatic or magnetic pattern, which is covered by group Fulltext... Hierarchy... Expanded...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 Fulltext... Hierarchy... Expanded...B41M.
