Scanner with automatic paper feeding function

Abstract

The invention provides a scanner with an automatic paper feeding function, being used for scanning files. The scanner comprises a body, a transmission mechanism and an optical module, wherein the transmission mechanism is arranged in the body and used for sequentially transferring the files to a first position and a second position; and the optical module is provided with an image catching region,and can be rotationally arranged in the body to be used for scanning the files passing through the image catching region. When the transmission mechanism transfers the files to the first position, the image catching region of the optical module faces the first position and scans the first surface of the files. When the optical module scans the second surface of the files, the transmission mechanism transfers the files to the second position, and the optical module rotates to enable the image catching region to face the second position and scan the second surface of the files.

Description

technical field [0001] The invention relates to a scanner with the function of automatic paper feeding, and in particular to a scanner with the functions of double-sided scanning and automatic paper feeding. Background technique [0002] Nowadays, scanners play a very important role in both home and business use. After scanning the content of the paper document, the scanner stores the content of the scanned paper document in the form of electronic data. [0003] In order to save paper, many documents have information on both sides, and many scanners on the market also provide the function of double-sided scanning. One of the technologies to achieve double-sided scanning is to configure a set of optical modules in the scanner, and to use a complex paper feeding path and a complex transmission control system to scan documents on both sides. Another technique is that two sets of optical modules opposite to each other are arranged in the scanner, and when the document passes t...

Problems solved by technology

[0004] However, both techniques mentioned above, no matter which one has its disadvantages

Let’s take the above-mentioned first technology first. The complex paper feeding path requires multiple sensors to sense the position of the document to be scanned, so that the transmission control system can correctly control multiple sets of rollers to transport the document to be scanned. so the cost is very high

Moreover, the design of the transmission control system is quite complicated due to the complicated paper feeding path inside the scanner.

Although the above-mentioned second technology does not require a complicated paper feeding path, it requires two sets of optical modules, so the cost also increases a lot
