Abstract
Abstract A method of reenlargement of microfilm originals stored in form of microimages includes providing a plurality of microimages on a carrier, selecting microimages from the plurality of microimages for reenlargement on a receiving medium, positioning a selected microimage in an image window suitable for the reenlargement, transferring the microimage on the receiving medium by an objective focused on the image window, during the transfer of the microimage on the carrier positioning a second microimage located on another carrier in a second image window and after the transfer of the first mentioned microimage, transferring the second microimage on the receiving medium.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
A method of reenlargement of microfilm originals stored in form of microimages, comprising the steps of providing a plurality of microimages on a carrier; selecting microimages from said plurality of microimages for reenlargement on a receiving medium; positioning a selected microimage in an image window suitable for the reenlargement; transferring the microimage on the receiving medium by an objective focused on the image window; during the transfer of the microimage on the carrier positioning a second microimage located on another carrier in a second image window; and after the transfer of the first mentioned microimage, transferring the second microimage on the receiving medium.
Claim 2
Independent Claim
103 words
A method of reenlargement of microfilm originals stored in form of microimages, comprising the steps of providing a plurality of microimages on a carrier; selecting microimages from said plurality of microimages for reenlargement on a receiving medium; positioning a selected microimage in an image window suitable for the reenlargement; transferring the microimage on the receiving medium by an objective focused on the image window; during the transfer of the microimage on the carrier positioning a second microimage located on another carrier in a second image window; and after the transfer of the first mentioned microimage, transferring the second microimage on the receiving medium.
Claim 3
Dependent Claim
32 words
The method as defined in claim 1, wherein after the transfer the first mentioned microimage a focus of the objective is adjusted from the first mentioned image window to second image window.
Claim 4
Dependent Claim
31 words
The method as defined in claim 1, wherein after transfer of the first mentioned microimage, the second image window which contains the second microimage is brought the focus of the objective.
Claim 5
Dependent Claim
45 words
The method as defined in claim 1, wherein a second objective is provided, said transferring including transferring the microimage located in said first image window through one of said objectives and transferring the microimage located in the second image window through another of said objectives.
Claim 6
Dependent Claim
90 words
The method as defined in claim 1, wherein the first mentioned carrier has a sequence of the microimages while the second carrier also has the sequence of microimages, said transferring being performed so that during the transferring of the sequence provided on the first mentioned carrier positioning of the sequence contained in the second carrier in the second image window begins, and after transferring of a last microimage of the sequence located on the first mentioned carrier the sequence located on the second carrier is transferred to the receiving medium.
Claim 7
Dependent Claim
50 words
The method as defined in claim 1, wherein more than two such carriers are provided and carry a predetermined number of microimages; and further comprising automatic exchange of the carriers and subsequent positioning of a next micro image determined for the reenlargement in a respective one of the image windows.
Claim 8
Dependent Claim
53 words
The method as defined in claim 1; and further comprising performing the reenlargement of microimages on the receiving medium in deviation from a sequence determined by the selection, and computing a new sequence in which a number or a time for adjustment of the focus and/or the exchange of the carriers is minimized.
Claim 9
Dependent Claim
117 words
An arrangement for reenlargement of microfilmed originals stored in form of microimages, comprising means for selecting a microimage for a plurality of microimages contained in a carrier for transferring the microimage to a receiving medium; a first image window in which the selected microimage can be positioned for the reenlargement; an objective focusable on said first image window for transferring the microimage to the receiving medium; a second image window arranged so that during the transferring of the microimage located on the first carrier a second microimage located on a second carrier can be positioned in said second image window, and after the transferring of first microimage the second microimage can be transferred to the receiving medium.
Claim 10
Dependent Claim
117 words
An arrangement for reenlargement of microfilmed originals stored in form of microimages, comprising means for selecting a microimage for a plurality of microimages contained in a carrier for transferring the microimage to a receiving medium; a first image window in which the selected microimage can be positioned for the reenlargement; an objective focusable on said first image window for transferring the microimage to the receiving medium; a second image window arranged so that during the transferring of the microimage located on the first carrier a second microimage located on a second carrier can be positioned in said second image window, and after the transferring of first microimage the second microimage can be transferred to the receiving medium.
Claim 11
Dependent Claim
49 words
An arrangement as defined in claim 8; and further comprising two independent positioning devices arranged to place microimages contained in the carriers in a respective one of said image windows; and means for adjusting a focus of said objective between said first image window and said second image window.
Claim 12
Dependent Claim
35 words
An arrangement as defined in claim 8; and further comprising an exchange device and a container receiving said carriers, said exchange device being operative to transport said carriers between said container and said positioning devices..
