Abstract
Abstract A photographic roller copier apparatus for photographing original copies having different side lengths onto a ribbon form copier material, the ribbon width corresponding to a desired copy size. The original copies have various formats and are provided in ribbon form, one format lying lengthwise in the ribbon direction and the other format perpendicular thereto. The apparatus consisting of a lens having an adjustable focal length so that from both formats of originals it is possible to make copies that are equal in size and that fill the width of the copier material ribbon, and that in the area of a picture gate the ribbon of originals is provided in a plane parallel to the lens axis. Between the picture gate end of the lens is provided a deflecting part which deflects the beams of light from the picture gate through 90° into a lens. The picture gate with the ribbon of originals, the illuminating apparatus and corresponding film rollers is rotatable around the lens axis through 90° to a smaller format position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
200 words
Photographic roller copier apparatus for photographing originals having different side lengths onto a ribbon shaped copier material, the ribbon width corresponding to a desired copy size, the originals being arranged in a ribbon form and having varying formats, one format lying in the lengthwise ribbon direction and the other format lying transverse thereto, said roller copier apparatus comprising: an illuminating device; lens means having an axis and a variable focal length, said focal length being variable to the extent that copies of equal size that fully fill the width of the copier material ribbon can be made from both original formats; a picture gate in the area of which the ribbon of originals is led in a plane parallel to said lens axis; a deflecting part located between said picture gate and said lens which deflects a path of flight from said picture gate through 90° into said lens; and a plurality of transport roller pairs for guiding said ribbon of originals, said picture gate, said deflecting part, said illuminating device, the ribbon of originals and said transport roller pairs being rotatable together through 90° about said lens axis to provide a smaller format position and a larger format position.
Claim 2
Dependent Claim

Photographic roller copier apparatus for photographing originals having different side lengths onto a ribbon shaped copier material, the ribbon width corresponding to a desired copy size, the originals being arranged in a ribbon form and having varying formats, one format lying in the lengthwise ribbon direction and the other format lying transverse thereto, said roller copier apparatus comprising: an illuminating device; lens means having an axis and a variable focal length, said focal length being variable to the extent that copies of equal size that fully fill the width of the copier material ribbon can be made from both original formats; a picture gate in the area of which the ribbon of originals is led in a plane parallel to said lens axis; a deflecting part located between said picture gate and said lens which deflects a path of flight from said picture gate through 90° into said lens; and a plurality of transport roller pairs for guiding said ribbon of originals, said picture gate, said deflecting part, said illuminating device, the ribbon of originals and said transport roller pairs being rotatable together through 90° about said lens axis to provide a smaller format position and a larger format position.
Claim 3
Dependent Claim
20 words
Roller copier apparatus as defined in claim 1, wherein said lens means includes two exchangeable lenses having different focal lengths.
Claim 4
Dependent Claim
20 words
Roller copier apparatus as defined in claim 1, wherein said lens means is a lens having an adjustable focal length.
Claim 5
Dependent Claim
39 words
Roller copier apparatus as defined in claim 1, wherein said illuminating device includes a lamp housing parallel to said lens axis and a deflecting element located so that it deflects light from said lamp housing into said picture gate.
Claim 6
Dependent Claim
15 words
Roller copier apparatus as defined in claim 4, wherein said deflecting element is a mirror.
Claim 7
Dependent Claim
15 words
Roller copier apparatus as defined in claim 4, wherein said deflecting element is a prism.
Claim 8
Dependent Claim
96 words
Roller copier apparatus as defined in claim 4, wherein said lamp housing is a supplemental unit oriented on said lens axis and further has an exit face; and further comprising a prismatic light conducting body located between said lamp housing exit face and said picture gate, said light conducting body being rotatable with said picture gate, said light conducting body being formed to transfer light from said lamp housing around the position of the plane of the ribbon of originals and opposite to said lens axis, and to further deflect the light into said picture gate.
Claim 9
Dependent Claim
42 words
Roller copier apparatus as defined in claim 1, wherein one said film roller pair is located before said picture gate and another said film roller pair is located after said picture gate, said film roller pairs being rotatable with said picture gate.
Claim 10
Dependent Claim
52 words
Roller copier apparatus as defined in claim 1; and further comprising at least one pusher located on said picture gate, and wherein said picture gate has a predetermined opening, said pusher being settable to produce the size of said opening to accommodate the smaller format when rotated into said smaller format position.
Claim 11
Dependent Claim
58 words
Roller copier apparatus as defined in claim 9; and further comprising a format mark located on said ribbon of originals, and a sensing device which senses said format mark and thereby controls the setting of said pusher and the rotation of said picture gate along with said illuminating device in accordance with the respective format of the original.
Claim 12
Dependent Claim
64 words
Roller copier apparatus as defined in claim 9, wherein said ribbon of originals has an edge having notches at fixed distances; and further comprising a sensing device for sensing the distances between said notches and thereby controlling the setting of said pusher and the pivoting motion of said picture gate along with said illuminating device in accordance with the respective format of an original.
