Problems solved by technology

But in the same way, the parts of the big roller are too bulky, the space design of the whole mechanism system has some restrictions, and the configuration of the parts is less flexible.
Moreover, the large rotational inertia of the large roller will increase the power burden of the system

Embodiment Construction

[0018] The basic structure and working principle of the automatic paper-feeding mechanism provided by the present invention will be described below in conjunction with illustrations.

[0019] see Figure 4 , the automatic paper feeding mechanism provided by the first embodiment of the present invention includes a paper input cassette 1 and a paper output cassette 2 . If the scanning area is taken as the central area, a paper feeding path 100 and a paper output path 200 are separated between the paper input tray 1 and the paper output tray 2 . Among them, the figure 1 The position shown in one of the scanning panels 6 is the scanning area.

[0020] On the paper feed path 100, at least one paper feed roller 10 and a paper feed idler 11 paired with the paper feed roller 10 are arranged, and the paper feed roller 10 and the paper feed idler 11 are kneaded to form a paper feed gap . On the paper discharge path 200, at least one paper discharge roller 20 and a paper discharge id...

Abstract

The invention relates to an automatic paper advance mechanism, mainly used in CIS type scanner. The mechanism comprises a pickup roller, a paper input path and a paper output path. The input path is equipped with a paper inputting roller and a matching idle roller to form a paper inputting gap; and the paper output path is equipped with at least one paper outputting roller and a matching idle roller to form a paper outputting gap. The invention is characterized in that: the automatic paper advance mechanism is further includes a carrying belt which is fitted onto the paper inputting roller and the paper outputting roller through the paper inputting gap and the paper outputting gap, and a driving motor which drives the paper inputting roller and the paper outputting roller.

Description

technical field [0001] The invention relates to an automatic paper-feeding mechanism, in particular to an automatic paper-feeding mechanism applied in a CIS type scanner to improve image quality. Background technique [0002] Most of the automatic paper feeding mechanism uses a roller set to feed the paper. After the paper is taken from the paper tray, it is conveyed through the scanning area through the rollers. At this time, the optical device captures the data in sections, and then organizes and combines them to obtain full image. The rollers at the front and rear of the scanning area, due to tolerance factors such as manufacturing and assembly, make the paper feeding speeds of the front and rear two sets of rollers different, resulting in unstable paper speed during the scanning process and affecting image quality. When the paper conveying speed increases upwards, the situation of unstable paper conveying speed becomes more obvious during the scanning process, which mak...
