Abstract
A copying apparatus provides that the magnification of a copy image of an original is reduced correspondingly to the width of a binding margin, so that when the formation of the binding margin on one edge portion of a transfer medium has been instructed, a part of the copy image does not extend beyond the other edge portion of the transfer medium, that is, all the area of the original is copied on an area of the transfer medium other than the binding margin.
Claims7
A copying apparatus capable of forming a binding margin at an edge portion of a transfer medium, the width of said binding margin being variable, said apparatus comprising:
- a movable photosensitive medium;
- a variable magnification projection optical system having a lens for projecting the optical image of an original to be copied onto said photsensitive medium;
- transfer means for transferring the image of the original to the transfer medium at a transfer station;
- instructing means for instructing the formation of a binding margin on a side edge portion of the transfer medium and the width of the binding margin to be formed;
- a first motor responsive to the instruction of said instructing means for displacing said lens in a magnification direction so as to change the magnification of the image of the original in accordance with the selected width of the binding margin;
- and
- a second motor responsive to the instruction of said instructing means for displacing said lens in a direction perpendicular to direction of movement of the photosensitive medium by a distance corresponding to the selected width of the binding margin.
A copying apparatus capable of forming a binding margin at an edge portion of a transfer medium, the width of said binding margin being variable, said apparatus comprising:
- a movable photosensitive medium;
- scanning means movable along a path for scanning an original, said path including a preparatory scanning section and an original scanning section;
- a lens for projecting the optical image of the scanned original onto said photosensitive medium;
- transfer means for transferring the image of the original onto the transfer medium at a transfer station;
- feeding means for feeding the transfer medium to the transfer station;
- instructing means for instructing the formation of a binding margin on the leading edge portion of the transfer medium and the width of the binding margin to be formed;
- variable timer means for controlling the operation of said feeding means, said variable timer means changing the time interval from when the leading edge of the original has been scanned until the leading edge of the transfer medium arrives at the transfer station in accordance with the selected width of the binding margin;
- and
- lens displacing means responsive to the instruction of said instructing means for displacing said lens in a magnification direction so as to cause the magnification of the optical image of the original projected onto said photosensitive medium to correspond to the selected width of the binding margin.
