Abstract
A copying apparatus having an original carriage capable of carrying thereon an original dimensionally corresponding to the combined area of two surfaces of a desired copy size is improved so that originals carried on the two surfaces at a time can be separately copied one by one.
Claims13
A copying apparatus comprising:
- an original carrier having a surface defining first and second contiguous areas for retaining thereon an original corresponding dimensionally to the combined area of two surfaces of a desired copy size;
- a photosensitive member;
- optical scanning means for scanning the entire area of the original by sequentially scanning the portions of the original retained respectively on said first and second contiguous carrier areas as said scanning means transverses first and second portions of an elongated scanning path, wherein each of said portions extends across one of said contiguous areas;
- means for forming an electrostatic image of the original on said photosensitive member;
- means for developing the electrostatic image;
- means for transfering the portions of developed image defined by the first and second portions of the scanning path onto separate copy material surfaces;
- and
- means for feeding copy material to said transferring means.

- an original carrier having a surface defining first and second contiguous areas for retaining thereon an original corresponding in dimension to the combined area of two surfaces of a desired copy size;
- a photosensitive member;
- optical scanning means for scanning the entire area of the original by sequentially scanning the portions of the original retained respectively on said first and second contiguous carrier areas as said scanning means transverse first and second portions of an elongated scanning path, wherein each of said portions extends across one of said contiguous areas;
- means for forming an electrostatic image of that portion of the original retained on said first carrier area on one side of the photosensitive member and forming an electrostatic image of the remainder of the original on the reverse side of the photosensitive member;
- means for developing an electrostatic image;
- and
- means for feeding and conveying the photosensitive member through said image forming means and said developing means.
