Problems solved by technology

[0002] In traditional image processing devices, such as scanning devices, printing devices and multi-function machines, the paper feeding mechanism is designed with a single roller, which has the following disadvantages: a single roller cannot load a large amount of paper, such as more than 100 sheets of paper; In addition, due to possible tolerances in the manufacturing of the rollers or wear and tear after use, it may cause the paper to shift left and right during the paper feeding process, which in turn affects the results of image processing

Embodiment Construction

[0045] Please refer to Fig. 1 to Fig. 3 at the same time. Fig. 1, Fig. 2 and Fig. 3 are respectively side, top and front schematic diagrams of the paper feeding mechanism 100 according to the present invention, wherein the paper feeding mechanism 100 of the present invention is used To feed the paper P and apply it to the image processing device. The paper feeding mechanism 100 includes: an upper casing 110 and a lower casing 112 opposite to the upper casing 110 , a paper feeder 114 , a main roller 120 , a paper separating device 130 , a first auxiliary lower roller 140 , and a first pressing element 142 , the second auxiliary lower roller 150 and the second pressing element 152 . Wherein, a paper feeding channel 170 is formed between the upper housing 110 and the lower housing 112 , and the paper feeder 114 is connected to the lower housing 112 for storing paper P to be fed. The main roller 120 is disposed on the lower casing 112 for feeding the paper P from the paper tray 1...

Description

technical field [0001] The invention relates to a paper feeding mechanism of a bottom feeding type and an image processing device using the paper feeding mechanism. The image processing device is, for example, a scanning device, a printing device, or a multifunction machine. Background technique [0002] In traditional image processing devices, such as scanning devices, printing devices and multi-function machines, the paper feeding mechanism is designed with a single roller, which has the following disadvantages: a single roller cannot load a large amount of paper, such as more than 100 sheets of paper; In addition, due to possible tolerances in the manufacture of the rollers or wear and tear after use, the paper may be shifted left and right during the paper feeding process, thereby affecting the image processing result. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a paper feeding mechanism, which is used to fe...
