BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variety of office equipment having an automatic document feeder for book scan. In particular, a single document image sensor can be used for automatic reading of a document and automatic reading of a document. It relates to a book scanning automatic feeder using a single close-up image sensor.

In general, a conventional automatic scanning device for book scanning, as shown in FIG. 1 and FIG. 2, a document stack 2 on which a plurality of documents 1 are stacked, and a document stacked on the document stack 2 ( 1) the feeding roller 3 for feeding paper, the friction pad 4 for contacting the feeding roller 3, and the sheet feeding paper 1, and the friction pad 4 for elastic contact with the feeding roller 3, respectively. Pressurized spring (5), guide (6) for guiding the feeding of the loaded document (1), close-up image sensor (7) for scanning an original (1), and scanning document (1) A scan roller 8 for bringing the paper into close contact with the close-up image sensor 7, an ejector 9 for ejecting the scanned document 1, a pinch roller 10, and a base 11 for supporting the paper feeder. And a cover 12 which is installed on the base 11 so as to be rotatable about the rotating shaft 12a to protect the paper feeder, the glass 14 on which the book 13 is placed, and the book 13. A book scanning contact image sensor 15 and a pinion 16 and a rack 17 for conveying the book scanning contact image sensor 15 during book scanning.

Referring to the overall operation of the conventional automatic book scanning automatic feeder configured as described above is as follows.

First, when the original 1 is scanned by the automatic document feeder, as shown in FIG. 1, when a plurality of originals 1 are placed on the original glass 2, the original 1 is placed on the paper feed roller 3. While being conveyed by the friction pad (4) and the pressure spring (5), the separated document (1) is scanned by the close image sensor (7) and the scan roller (8) for scanning the original, and the scanned document ( 1) is discharged by the eject controller 9 and the pinch roller 10.

Next, when scanning the book 13, as shown in (b) of FIG. 2, the book 13 is placed on the glass 14 while the cover 12 is rotated about the rotating shaft 12a. When the 16 is rotated, the book scanning close-up image sensor 15 is transferred by the rack 17 to perform book scanning. When the book scanning is completed, the cover 12 is again covered as shown in FIG.

However, such a conventional book scanning automatic feeder uses two close image sensors such as the close image sensor 7 for document cans and the close image sensor 15 for book scanning to perform original scan and book scan. There is a problem in that the structure is complicated, the size of the product is difficult to miniaturize, and the cost is increased due to the use of two close contact image sensors.

An object of the present invention is to reduce the cost and downsizing by simultaneously performing book scanning and document scanning automatic feeding using only one contact image sensor in order to solve the above-mentioned drawbacks. To provide a book-scan automatic feeder using a single close-up image sensor.

Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.

As shown in FIG. 3 and FIG. 4, the present invention provides a paper feed for separating and feeding the first document guide 20 on which a single document A is stacked, and the original paper stacked on the first document guide 20. Means 30, the cover 80 is installed to be rotatable to protect the paper feeding means 30, and the second document guide 90 is installed in the lower portion of the cover 80 for seating the book during book scanning And an image installed under the second document guide 90 to scan a sheet document A fed into the sheet feeding means 30 or a book seated on the second document guide 90, respectively. The sensor 50 and the pinion 100 and the rack 110 which transfer the close image sensor 50 along the second document guide 90 when the book is scanned are the basic features of the technical configuration.

Here, the feeding means 30 is a feeding roller 31 for feeding a single document A into the first document guide 20, and a friction for feeding a single sheet of paper A in contact with the feeding roller 31. The pad 32 and the pressure pad 33 which elastically contact the paper feeding roller 31 with the friction pad 32 are comprised.

Referring to the overall operating relationship of the present invention configured as described above in detail.

First, when reading the single document A by the automatic document feeder, as shown in FIG. 3, when the single document A is placed on the first document guide 20, the original A is fed into the feed roller ( 31 is separated by the friction pad 32 and the pressure spring 33 while being transported by, the separated sheet of document (A) is transported along the guide 40 while the close image sensor 50 and the scan roller 70 The original document A is read by and is discharged by the scan roller 70 and accumulated in the discharge tray 60. At this time, the scan roller 70 serves to bring the sheet (A) in close contact with the image sensor 50 in close contact with the document reader, and discharge the read document (A) to the discharge tray 60 at the same time, To perform.

Next, when reading the book B, as shown in (b) of FIG. 4, the book B is placed on the second document guide 90 while the cover 80 is rotated about the rotation shaft 81. When the pinion 100 is placed and rotated, the close image sensor 50 is transferred by the rack 110 to perform book reading, and when the book reading is completed, the cover 80 is covered again as shown in FIG.

Therefore, the present invention can perform book reading and document reading with one close-up image sensor 50, and also the jackroller and pinch roller which have been used in the conventional structure for ejecting a single sheet of paper are deleted. The simple structure has the advantage of reducing the product size and cost.

As described above, the present invention can simultaneously perform book scanning and sheet document scanning automatic feeding by using only one contact sensor, thereby reducing the cost of the book feed automatic feeding device and reducing the size thereof. That is a very useful invention.
