Copying apparatus

Claim 2

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.

Claim 3

A copying apparatus according to claim 1, further comprising: a first movable carriage driven by said first motor; first guide means for guiding said first carriage along the optical path; a second movable carriage driven by said second motor; and second guide means for guiding said second carriage. in the direction perpendicular to the direction of movement of the photosensitive medium; one of said first and second movable carriages being movably mounted on the other carriage, said lens being mounted on said one of the first and second movable carriages, and the guide means for said one of the first and second carriages being mounted on the other carriage.

Claim 4

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.

Claim 5

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.

Claim 6

A copying apparatus according to claim 3, further comprising: detecting means for detecting the position of said scanning means and generating a signal when said scanning means reaches a predetermined position in said path, wherein said detecting means detects that said scanning means reaches a position for scanning the leading edge of the original, and said variable timer means operates in response to the signal generated by said detecting means.

Claim 7

A copying apparatus according to claim 4, further comprising scanning speed changing means for changing the speed of said scanning means corresponding to said ratio.

Claim 8

A copying apparatus according to claim 5, further comprising a supporting table to support the original, said table having an edge for positioning the leading edge of the original.

Claim 9

A copying apparatus according to one of claims 4, 5 or 6, wherein said variable timer means actuates said feeding means at a time delayed by the time corresponding to said selected width of the binding margin from the time at which said sensing means produced said signal.
