An automatic document feeder for an image processing machine. A main frame is so mounted as to be pivoted with respect to a platen glass provided on the housing of the image forming machine. A paper feeding unit is provided at one end of the main frame, and a paper discharging unit is provided at the other end. A conveyer belt mechanism is disposed between the paper feeding unit and the paper discharging unit. A document-placing table is attached to a table support means provided for the paper feeding unit, and is allowed to move in the back-and-forth direction of the image forming machine, so that its position can be adjusted, thereby permitting adjustment of any deviation between the optical axis of the image forming machine and the center line of the document fed by the automatic document feeder. The paper feeding unit is further provided with an open/close frame pivotally mounted on the main frame by at least one hollow split-bearing. An electrical wire is inserted within the hollow cylindrical portion of the split-bearing in order to eliminate the need to adjust the movement of the electrical wire with the rotation of the open/close frame.
摘要:
An automatic document feeder for an image processing machine. The document feeder includes a main frame to be pivotally mounted on the image processing machine, a paper feeding unit, a paper discharging unit, and a conveyer belt for conveying papers from the paper feeding unit, across the image processing machine for image processing, to the paper discharging unit for discharge. A document discharging tray is positioned above the conveyer belt for receipt and stacking of papers discharged from a discharge port of the paper discharging unit. In the direction of document discharge, the document discharging tray has an ascending inclination, followed by a descending inclination. The ascending inclination and the descending inclination define a vertex spaced from the discharge port in the document discharging direction by more than one-half the length of the maximum-length document to be processed by the image processing machine.

摘要:
An automatic document conveying apparatus in which a normal continuous document conveying state and a single document conveying state, suitable for a document having high importance such as an original of a design, can be selectively determined, and carrying and discharging of documents can be fully well conducted. In a document carrying passage, a restricting member and a separation roller which cooperate with a feed roller are disposed. The forward end of the restricting member approaches or contacts the feed roller, and the separation roller is driven to rotate in a direction opposite to the document conveying direction in the continuous document conveying state. In the single document conveying state, the restricting member is isolated from the feed roller, and the separation roller can be freely rotated.
摘要:
In a primary paper feeding device, a document is conveyed from a document stock section to a pair of registration rollers by a first conveying device. The document conveyed to the registration rollers is further conveyed forward in a downstream direction by the registration rollers. When the lead (downstream) edge of the document arrives at a predetermined first reference position downstream of the registration rollers, document conveying by the registration rollers terminates. In this way, the document is conveyed such that the trailing edge thereof does not pass through the registration rollers. Thereafter, when a document change signal occurs, the registration rollers again are driven so that the document advances toward a position for document reading.
