Description

Document guide structure for automatic document feeder {Structure for guiding document of ADF}

The present invention relates to a structure for guiding a document at the time of feeding and discharging the document in an automatic document feeder (ADF; Auto Document Feeder) of the document reading machine. A document guide structure of an automatic document feeder for implementation.

In a scanner that is a document reading device, a sheet-feed type scrnner in which an optical unit is fixed and a document is scanned while the document is moved has a U-turn paper path. An automatic paper feeder (hereinafter referred to as ADF) is applied, and an example of such a scanner will be described with reference to FIGS. 1 and 2.

The sheet feed type scanner includes a scanner main body 10, an ADF 20 provided in front of the upper surface of the scanner main body 10, a paper feeder 30 and a discharge tray 40 installed at the rear of the ADF 20. Consists of

An optical unit 11 for scanning originals is provided on the inside of the scanner main body 10, and the ADF 20 feeds the feed roller 21 and the originals fed into the apparatus by the feed roller 21. White roller 23 to be in close contact with the optical unit 11, a feed roller 25 for U-turning the scanned document by the optical unit 11, and a document U-turned by the feed roller 25 Discharge roller 27 for discharging the discharge is provided, the manual guide 31 for aligning the feeding support is provided on the paper tray 30 so as to be movable to the left and right.

In the operation of the sheet feed type scanner configured as described above, the documents are fed by the ADF 20 after the plurality of documents to be scanned on the tray 30 are aligned using the manual guide 31. The document fed into the ADF 20 by the paper feed roller 21 is scanned while passing in close contact with the optical unit 11 by the white roller 23, and the scanned document continues to be scanned. It is U-turned by the feed roller 25 and is conveyed to the discharge roller 27 side, and is discharged to the outside of the ADF 20 by the discharge roller 27. Originals discharged from the ADF 20 are sequentially stacked on the upper surface of the discharge tray 40.

However, the document guide structure of the conventional automatic document feeder as described above is used because the manual guide 31 of the feeder is located under the discharge tray 40 and is not exposed to the outside. There is a problem that it is inconvenient to operate the manual guide 31 to align the.

In addition, since the paper tray and the discharge tray are in a separated state, the size of the structure for feeding and discharging the document by the ADF 20 apparatus becomes large as a whole, which makes it difficult to reduce the size of the entire apparatus.

The object of the present invention devised in view of the above problems is to provide a document guide structure of an automatic document feeder that facilitates the alignment of the originals loaded on the tray, and the alignment of the discharged originals. have.

Another object of the present invention is to provide a document guide structure of an automatic document feeder, which simplifies and reduces the size of the entire machine by simplifying the feeding and discharging structure of the ADF.

The document guide structure of the automatic document feeder for achieving the object of the present invention as described above is a feeder on which a document before scanning is loaded on the rear side of the ADF provided on the upper surface of the document reader, and both sides of the feeder. The manual guide is provided to be movable in the width direction in the manual guide, characterized in that for forming the discharge portion is loaded with the document discharged after scanning.

It is preferable that the guide part is formed so that the originals stacked on top of the discharge part are aligned.

Preferably, the discharge portion and the guide portion are formed integrally with the manual guide.

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail based on the accompanying drawings.

Figure 3 is a cross-sectional view of the document guide structure of the automatic document feeder according to the present invention, Figure 4 is a side view of FIG.

As shown in the drawing, the preferred embodiment of the present invention excludes the configuration of the discharge bin on the upper side of the tray, and plays a role of the discharge zone on the manual guide 50 installed to be movable from the upper side of the tray 30 to the left and right sides. The discharge part 51 to be performed is integrally formed in parallel with the document discharge direction, and the guide part 53 which guides the discharged document is guided and is automatically formed on the upper side.

Guide portion 53 of the manual guide is preferably formed to be inclined to the outside with a predetermined inclination angle as in the embodiment.

The configuration of the sheet feed type scanner to which the document guide structure of the automatic document feeder is applied, that is, the scanner main body 10, the ADF 20 provided in front of the upper surface of the scanner main body 10, and the ADF 20. It consists of a feed tray 30 and a discharge tray 40 which is installed at the rear, the optical unit 11 for scanning an original is provided on the upper inside of the scanner main body 10, the ADF 20 has a paper feed roller ( 21), the white roller 23 which closely adheres the document fed into the apparatus by the feed roller 21 to the optical unit 11, and the document scanned by the optical unit 11 in a U-turn. The feed roller 25 and the discharge roller 27 for discharging the document U-turned by the feed roller 25 are the same as in the prior art, and the same parts have the same reference numerals.

The operation of the scanner to which the inventive device configured as described above is applied will be described.

First, the original to be scanned is placed on the tray 30, and then the original is aligned by appropriately moving the manual guide 50 to the left or the right. At this time, the originals placed on the tray 30 by the manual guide 50 are aligned, and the position of the discharge unit 51 of the manual guide is set, and the position of the guide unit 53 integrally formed with the discharge unit is set. do.

In this state, the document placed on the paper tray is sequentially fed by the paper feed roller 21 of the ADF 20 and scanned by the white roller 23 in close contact with the optical unit 11. The scanned document is then U-turned by the feed roller 25 to be fed to the discharge roller 27 side, and discharged to the outside of the ADF 20 by the discharge roller 27.

Originals discharged from the ADF 20 are sequentially stacked on the discharge unit 51 of the manual guide, and the originals are loaded in an aligned state by the guide unit 53 of the manual guide.

As described above, according to the document guide structure of the automatic document feeder according to the present invention, the discharge tray is excluded, and the manual guide provided in the tray serves as the discharge tray, and the alignment of the discharged documents is performed. As a structure, there is an effect that the operation of the manual guide can be easily performed, and there is an advantage that the structure can be simplified and the size of the entire apparatus can be made light and small.
