Problems solved by technology

The main problem is that the design of the mechanism disclosed in the previous case is quite complicated, and there are many moving parts, which will make it difficult to maintain in the future, and the product is also relatively large.
In addition, it should be emphasized that too many active components can easily cause paper jams, especially when scanning and printing on the other side of the paper, there will also be wrinkles, resulting in troubles in use

Abstract

The invention relates to a document feeder and the method for turning over paper. It contains document feed roller, which is connected to one end of brake component. Paper pressing component is on the other end of the brake component that could rotate driven by the brake component. The paper turning over method includes the following steps: putting the paper into the first paper feed path, pressing the paper into the second paper feed path while the paper leaving the first paper feed path, the paper would be turned over after coming into the first paper feed path again. The invention is simple structure, and could effectively reduce paper block phenomena.

Description

【Technical field】 [0001] The invention relates to a paper conveying mechanism, which is applied to a scanning and printing device, especially a paper conveying device with double-sided paper conveying performance. 【Background technique】 [0002] Scanning and printing devices have generally appeared in the daily life of the general public, especially in major enterprises and even general company lines, copying and archiving of documents and related printing and scanning operations. This device plays a pivotal role. [0003] Scanning and printing devices such as fax machines, printers, scanners or Multi Function Printers (MFPs), if there are data on both sides of the paper and need to be read, copied or printed, except In addition to manually turning over the materials to be printed, there are also many technologies that have been published and known to the public by setting mechanisms in the product to perform paper double-sided printing and scanning. For example, US Patent ...
