Abstract
An automatic document conveyer for use with a photoelectric copier which copies an image of a document at a platen of the photoelectric copier onto a copying sheet. The document conveyor includes a first conveyor part for conveying the documents one by one to the platen, and a second conveyor part for conveying the documents from the platen to the outside of the photoelectric copier after a copying operation. The first conveyor part conveys the documents at either a fast speed or a slow speed, and conveys the documents at the slow speed while a forwarded document is placed at the platen.
Claims9
An automatic document conveyance apparatus for use with a photoelectric copying device for copying an image of a document, at a document copying position of said photoelectric copying device, onto a copying sheet, comprising:
- first conveyance means for conveying a plurality of documents in a sheet form one-by-one to a document waiting position in said document conveyance apparatus;
- second conveyance means for conveying said documents from said documents waiting position to said document copying position;
- third conveyance means for conveying said documents from said document copying position to a position outside of said photoelectric copying device after a copying operation of said photoelectric copying device;
- and
- means for controlling the second and third conveyance means so that a document held at said document waiting position and a document at said document copying position are automatically ejected outside of said automatic document conveyance apparatus when a copying operation is cancelled,
- wherein the second conveyance means includes means for holding one of said documents conveyed to said document waiting position thereat until said copying operation for another of said documents previously conveyed to said document copying position is ended.
An automatic document conveyance apparatus for use with a photoelectric copying device for copying an image of a document, positioned at a document copying position of said photoelectric copying device, onto a copying sheet, comprising:
- first conveyance means for conveying a plurality of document in a sheet form one-by-one to a document waiting position in said document conveyance apparatus;
- second conveyance means for conveying said documents from said document waiting position to said document copying position;
- third conveyance means for conveying said documents from said document copying position to a location outside of said photoelectric copying device, after a copying operation of said photoelectric copying device;
- and,
- means for controlling the conveyance speed of at least one of said first conveyance means, said second conveyance means, and said third conveyance means, when said copying sheet jams in said document copying device, to be a non-zero speed which is lower than that of said least one conveyance means when said document copying device operates a copying operation,
- wherein the second conveyance means includes means for holding one of said documents conveyed to said document waiting position thereat until said copying operation for another of said document previously conveyed to said document copying position is ended.
An automatic document conveyance apparatus for use with a photoelectric copying device for copying an image of a document, at a document copying position on a platen of said photoelectric copying device, onto a copying sheet, comprising:
- first means for separating and conveying a plurality of documents in a sheet form one-by-one to an intermediate position;
- second means for conveying said documents from said intermediate position to said document copying position and then conveying said documents from said document copying position to a document ejecting position, which position is not on said platen, the second means including a conveyance belt covering said platen so as to slide said document on said platen;
- said conveyance belt capable of simultaneously sliding two sheets of said documents on said platen so that, after copying the image of a first document at said document copying position, said conveyance belt ejects said first document from said document copying position to said document ejecting position while conveying a following second document from said intermediate position to said document copying position;
- and
- means for controlling said second means to move said conveyance belt at a high or low speed so that, when said conveyance belt simultaneously slides two sheets of said documents on said platen, said second means moves said conveyance belt at said high speed, and when said conveyance belt slides a single sheet of said documents on said platen, said second means moves said conveyance belt at said low speed to reduce friction between said conveyance belt and said platen.
