专利汇可以提供Document presentation device for use with copying machines专利检索，专利查询，专利分析的服务。并且A document presentation device which can place a series of preselected overlays into register with an original document and with the copying aperture of a document reproducing machine. The overlays form a web and are arranged in two groups separated from each other by an empty field which registers with the aperture when the machine is to make prints without images of overlays. The overlays of one group represent the first sheets and the overlays of the second group represent the second sheets of twosheet invoices, reminders, acknowledgments or the like. The operation is automatic as regards the sequence of moving selected overlays into register with the aperture, making a desired number of prints from selected overlays, counting the number of finished prints, resetting the empty field of the web into register with the aperture upon completion of printing from a sequence of overlays, and indicating the extent of completion of a sequence of selected copying operations.，下面是Document presentation device for use with copying machines专利的具体信息内容。

权利要求

1. A document presentation device for use with a document reproducing machine having a copying aperature over which an original document to be reproduced is placed, comprising means for supporting an original document in register with the copying aperture; a plurality of overlays including several groups of overlays wherein each overlay of one group is related to an overlay of another group; drive means for moving selected overlays into register with the copying aperture; selector means actuatable to select the sequence in which successive selected overlays of a group are moved into register with the copying aperture by said drive means; and counter means for determining the number of copy sheets to be made from the original document and that oVerlay which registers with the copying aperture.

2. A device as defined in claim 1, wherein said overlays together form an elongated web and said drive means comprises first and second reels each connected with a different end of said web, first motor means for rotating said first reel in a direction to draw the web from the second reel, and second motor means for rotating said second reel in a direction to draw the web from said first reel.

3. A device as defined in claim 2, wherein said selector means comprises discrete actuating elements for each overlay of one of said groups.

4. A device as defined in claim 2, wherein said web includes an empty field between said one group and said other group of overlays.

5. A device as defined in claim 4, wherein the overlays of said one group constitute the masters of the first sheets of sets of two copy sheets each and the overlays of said other group constitute the masters of the second sheets of the respective sets of two copy sheets each.

6. A device as defined in claim 4, wherein said selector means comprises a discrete actuating element for each overlay of said one group and the related overlay of said other group.

7. A device as defined in claim 6, further comprising discrete first and second starter means for said machine, one of said starter means being arranged to start said machine where said aperture registers with the first selected overlay of said one group and the other of said starter means being arranged to start said machine when said aperture registers with the first selected overlay of said other group.

8. A device as defined in claim 1, further comprising additional counter means arranged to record the number of copy sheets produced by said machine from an original document and the overlay which registers with said aperture.

9. A device as defined in claim 8, further comprising means for comparing the number of copy sheets recorded by said additional counter means with the number of copy sheets selected by said first mentioned counter means for the overlay which registers with said aperture and for arresting said machine when the recorded number of copy sheets matches the selected number.

10. A device as defined in claim 1, further comprising means for indicating the extent of completion of a selected sequence of copying operations.
