Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic document feeder having a stitching means for stitching copied documents.

Prior Art Conventionally, when copying documents that have been stapled together using staples or the like, it is necessary to first remove the staples, separate the documents, and then stitch them together again after copying, which is a troublesome operation.

Purpose of the Invention The present invention has been made with the aim of improving the above-mentioned problems, and is an automatic method that automatically stitches the originals after copying by means of a stitching means that is provided in the original storage section of the main body so as to be freely removable. By providing a document feeding device, troublesome binding operations after copying are unnecessary.

Structure of the Invention A part of the document storage section that stores the document to be copied is provided with a part that protrudes into the document storage section when copying is completed.
An automatic document feeder is provided with a stitching means for stitching together documents stacked in a document storage unit after copying, so that documents separated during copying can be automatically stitched after copying.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the figure, reference numeral 1 denotes a main body of this apparatus installed above the platen 3 of a copying machine 2, and a document storage for storing a document 4 to be copied. It has part 5. A vacuum feeder 7 is provided below the document exit 6 of the document storage section 5, and above the vacuum feeder 7, the leading edge of the document 4 stored in the document storage section 5 is moved through the vacuum feeder by air pressure. An air knife 8 that presses against Ida 7 is installed. The vacuum feeder 7 has a plurality of endless field belts 1 wound around a plurality of rollers 9, for example, four rollers 9.
0, and a suction means 11 that sucks the original 4 located at the bottom of the original 4 stored in the original storage section 5 and presses it onto the field belt 10. As the field belt 10 rotates, the original document 4 is carried through the conveyance path 12 between the platen 3 and a conveyance belt 13 provided on the platen 3. The conveyor belt 13 is wound between rollers 14 provided on both ends of the platen 3, and conveys the carried original 4 along the upper surface of the platen 3 to a copying position, and after copying, carries it out from above the platen 3. It's becoming like that. The document 4 carried out from the platen 3 is circulated by the roller group 15 through the conveyance path 16 to the document storage section 5, and is stacked on top of the documents 4 stored in the document storage section 5.

On the other hand, a document guide 17 is provided in the document storage section 5 and is movable according to the size of the document.
The document guide 17 and the resist side plate 5a of the document storage section 5 regulate the conveyance position of the document 4, and the resist side plate 4a is provided with a through hole 5b. The binding means 18 is designed to protrude freely. The stitching means 18 is, for example, an automatic stapler, which projects into the document storage section 5 through the through hole 5b in response to a copy completion signal for all documents 4, and the plurality of sheets stacked in the document storage section 5 after copying is completed. The document 4 is configured to be automatically bound at the binding position of the manuscript 4, for example, the upper left corner of the manuscript 4.

Effects of the Invention As described in detail above, the present invention has a through hole in the side plate facing the document guide provided in the document storage section that accommodates the document to be copied, and a passage through the through hole toward the document storage section. Since the stitching means is provided so as to be freely retractable, the documents stacked in the document storage section after copying can be automatically stitched together by the stitching means.

This eliminates the need for a troublesome document binding operation after copying, resulting in a significant improvement in operability.

In addition, since the stitching means is recessed into the side plate except when stitching, it may get in the way when loading and unloading documents into the document storage section, and the stitching means may interfere with document feeding when loading and unloading documents. In addition, since the binding means is provided on the side plate facing the document guide,
To make it possible to always stitch documents at a predetermined position even if the sizes of the documents vary.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention, with FIG. 1 being an overall schematic sectional view and FIG. 2 being a perspective view of the main parts. 4 is a document, 5 is a document storage section, and 18 is a binding means.
