Class 355 :: PHOTOCOPYING

Definition

GENERAL STATEMENT OF THE CLASS SUBJECT MATTERA. This class provides for apparatus and methods for photos:graphically copying information from an original or carrier that is not classified elsewhere, generally employing a concentrated source of light and an image receiving medium with a photosensitive emulsion surface.

B. Various plural and composite types of copies are included such as those involving plural projected images including multicolor and duplex.

C. Copies selective at the operator's choice are also included where one original of a group of similar originals may be selected for copying.

D. Certain combinations, subcombinations and perfecting features are included such as with film developing or severing, with temperature control, and with a viewing screen. Included also are subcombinations which are peculiar to copies such as holders for the original or photosensitive paper. The class also contains improvement in particular elements of or their relationship to the copies when the elements are claimed in combination with other photos:graphic copying structure. These improvements may be in filters, shutters, gates, reflectors, lens mounts, condensers, or means to convey the original.

E. Methods of copying are also provided for here where all the steps are for copying a sheet film strip.

LINES WITH OTHER CLASSESPHOTOCOPYING APPARATUS CLASSIFIED ELSEWHEREXerographic copying methods and apparatus which utilize invisible radiation, for infrared or thermal image document pattern copying methods or apparatus, and methods and apparatus to expose by invisible radiant energy a recording detector are classified elsewhere. Copying structure or methods including specific chemical emulsions on the photosensitive paper are classified elsewhere. Copying which includes the use of a motion picture camera or a motion picture projector is provided for elsewhere. However, this class, 355, has means for copying motion picture film which does not include such motion picture camera or projector. (See References to Other Classes, below.)PHOTOCOPYING APPARATUS COMBINED WITH OTHER STRUCTURE AND CLASSIFIED ELSEWHEREPatents which claim apparatus for photographing plural images such as an object and a carrier (e.g., an identification card) are classified elsewhere. Photocopying which includes forming a television image where a detailed cathode-ray tube is claimed; where only a nominal cathode-ray tube is set forth is classified elsewhere. The combination of a detailed register with a broadly or specifically claimed copier is classified elsewhere. (See References to Other Classes, below.)PHOTOCOPYING SUBCOMBINATIONS CLASSIFIED ELSEWHEREFilm advancing mechanisms where no more than a nominal optical or photocopying element is claimed is classified elsewhere. Photographic lights and projection lights, per se, are elsewhere. Sheet feeding or delivering means where no specific optical or photographic structure is set forth is classified elsewhere. Lenses, reflectors, and optical filters are provided for elsewhere.
