Problems solved by technology
[0009] Although the traditional automatic paper feeding device 10 can adjust the passage height of the paper feeding passage 104 by means of the passage adjustment module 106, the passage adjustment module 106 must additionally be equipped with a moving mechanism 1062, which not only occupies the space inside the casing 101 but cannot reduce the size of the traditional automatic paper feeding device. Due to the volume of the paper device 1, the moving mechanism 1062 must be connected to the driving device (generally a motor), thus increasing the load of the traditional automatic paper feeding device 10

Embodiment Construction
[0081] In view of the defects of the traditional technology, the present invention provides an automatic paper feeding device. see image 3 , which is a schematic side view of the structure of the automatic paper feeding device in a preferred embodiment of the present invention. Similar to the conventional automatic document feeding device 10 , the automatic document feeding device 20 is disposed on a flatbed scanner 22 and combined with the flatbed scanner 22 to form an automatic document feeding scanning device 2 . The automatic paper feeding device 20 includes a housing 201, a first paper tray 202, a second paper tray 203, a first paper pickup roller set 204, a second paper pickup roller set 205, and a paper feed channel 206 , a plurality of paper feeding roller sets 207, a pressing structure 208, a guide groove 209 (see Figure 4 ), a plurality of first paper guide ribs 210, a plurality of second paper guide ribs 211, a paper output roller set 212, a paper output box 213...

The invention relates to an automatic paper feeding device comprising a shell, a propping structure arranged at the bottom of the shell, a guide slot arranged on the propping structure, multiple first paper guiding ribs and multiple second paper guiding ribs. Multiple first paper guiding ribs are arranged at the downstream part of the guide slot, and multiple second paper guiding ribs are adjacent to multiple first paper guiding ribs, wherein the height of each first paper guiding rib is less than that of each second paper guiding rib. A lower first paper guiding rib is used for guiding a thicker paper sheet, and a higher second paper guiding rib is used for guiding a thinner paper sheet. In the automatic paper feeding device provided by the invention, paper sheets with different thickness are fed into a paper feeding channel by virtue of the changed structural design, the volume of the automatic paper feeding device can be reduced while a moving mechanism is not required to be arranged, and a power and moving mechanism provided by a power plant is not required to be dispersed, thus the load of the automatic paper feeding device is not increased.
Description
technical field [0001] The invention relates to an automatic paper feeding device, in particular to an automatic paper feeding device capable of feeding papers of different thicknesses. Background technique [0002] The early scanning device can only scan the image of a single document. When the user wants to scan a stack of documents, he must take out the scanned document and place the next document on the scanning device after the scanning device scans a document. Scan the next document. In view of the troublesomeness of manually replacing documents, an automatic document feeder, commonly known as the Automatic Document Feeder (ADF), has been developed on the market. It is used with a flatbed scanner and can complete a stack without manual document replacement. Scanning of documents, even double-sided scanning of documents. [0003] In the traditional automatic paper feeding device, the internal paper feeding channel is specially designed for paper with a general thickne...
