つた。BACKGROUND ART Conventionally, as a document feeder for automatically supplying documents to a copying machine or the like, there is a document feeder that is provided with a vacuum conveyance mechanism at a document exit. The vacuum transport mechanism is composed of an endless transport belt and a suction means that sucks the originals to be transported and brings them into close contact with the transport belt, and transports the originals stored in the original storage section one by one from the bottom and copies them. It is designed to be fed onto the machine's platen. However, in conventional automatic document feeders, if the leading edge of a document stored in the document storage section is curled, the leading edge of the document will rise as soon as it is ejected from the document storage section, overcoming the suction force of the suction means. There were problems with documents not being able to be fed out smoothly, such as misfeeds occurring when the paper got caught in the paper exit.

稿収納部４へ送り込まれるようになつている。Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the figure, 1 is the main body of this device placed on the platen 3 of a copying machine 2. A document storage section 4 with an open top is provided at the center of the upper part, and the document 5 to be copied is stored in this document storage section. It is housed in a stacked state of 4. Reference numeral 6 denotes a vacuum conveyance mechanism provided at the lower part of the document storage section 4 on the side of the document exit 7, which includes an endless feed belt 8 that is rotated in the direction of the arrow by a drive system (not shown), and a vacuum conveyance mechanism that sucks the document 5 and transports the document 5 to the feed belt. A suction means 9 such as a blower that presses onto the document storage section 4 sucks the documents 5 stored in the document storage section 4 one by one from below, and the feed belt 8 transfers them from the outlet 7 through the conveyance path 10 to the platen 3. , and is adapted to be sent between conveyor belts 11 provided above. The conveyor belt 11 is provided with its lower side along the upper surface of the platen 3, and conveys the imported original 5 onto the platen 3, and after copying is completed, it is discharged to the outside of the main body 1 from the discharge port 12, or is reversed. The document is then sent to the document storage section 4 again.

である。 On the other hand, an air knife 13 is installed above the document exit port 7 of the document storage section 4 . The air knife 13 is equipped with a large number of nozzles 13a that eject compressed air toward the leading edge of the original document 5, and the compressed air jetted from these nozzles 13a serves to split the leading edge of the stacked original documents 5. There is. Also, approximately triangular curl presser pieces 14 are provided horizontally at the corners on both sides of the document exit 7, and by immediately pressing the leading end corner of the document 5 from above, the document 5 can be curled. is becoming suppressed. Note that 15 is a side guide.

る。Effects of the Invention As described in detail above, the present invention is provided with curl presser pieces near both sides of the document exit port 7 of the document storage section 4 to suppress curls that occur at the leading edge of the document 5. As soon as the document 5 is carried out from the document storage section 4, curling is suppressed by the curl pressing piece A. In other words, the curled original 5
When stacking the documents and storing them in the document storage section 4, the upper document 5
Although the curl of the lower document 5 is suppressed by the weight of
When the document is carried out from the document storage section 4 by the vacuum transport means 6, the suppressing force due to the weight of the upper document is lost and the document tends to curl. Since curling is continuously suppressed, the leading edge of the document 5 does not get caught in the document exit port 7, and as a result, misfeeds and paper jams do not occur, so the document 5 can be reliably fed to a copying machine, etc. become able to.
