Sheetfed scanner with business card feed mechanism

Abstract

The invention relates to a sheetfed scanner with a business card feed mechanism, which is used for scanning a image of a file or a business card. The sheetfed scanner comprises a scanning module, a file paper feed tray, a file paper extraction rolling wheel, a paper out tray, a paper feed channel, a plurality of transmission rolling wheels, a business card paper feed tray and a business card paper extraction rolling wheel group; the business card paper feed tray comprises a business card supporting plate, a paper clamping button and a paper combing sheet, the business card supporting plate is used for placing the business card; the paper clamping button is connected the business card supporting plate and is pressed by a user to lead the business card supporting plate to swing; the paper combing sheet is used for providing friction force for the business card. When the business card which is placed on the business card supporting plate is fed by the business card paper extraction rolling wheel group, the paper clamping button is not pressed, and the business card paper feed tray is in a state of paper feed; when the business card which is placed on the business card supporting plate is fed by the business card paper extraction rolling wheel group and the paper clamping occurs, the business card feed tray is in a state of releasing so that the business card can be drawn out.

Description

technical field [0001] The invention relates to a scanner, in particular to a paper-fed scanner capable of feeding files and business cards. Background technique [0002] The main function of the scanner is to capture images to convert the content of paper documents into electronic documents by scanning, so that users can disseminate, organize or save them. As scanner technology matures, scanners are becoming more and more popular. [0003] The earliest scanners can only scan images on one side of a document. When users want to scan images on both sides of a document, they must manually turn over the document so that the scanner can scan the image on the other side of the document. In view of the fact that manual flipping is too cumbersome, an automatic sheet-feeding scanner that does not need to be manually flipped has been developed on the market, so that users only need to place a stack of documents on the paper tray of the sheet-fed scanner, and there is no need for man...

AI Technical Summary

Problems solved by technology

However, it is not feasible for the user to use a general sheet-fed scanner to feed and scan business cards, because the size of the business card is smaller than that of a general document, and the gap between the transmission rollers in a general sheet-fed scanner is for general documents. The file size is designed so that when a normal sheet-fed scanner is used to feed and scan a business card, the business card will be fed by the transport roller to a position where it cannot touch the next transport roller and stops between the two transport rollers

Furthermore, since business cards are thicker than ordinary documents, they cannot be bent and fed like documents in ordinary sheet-fed scanners.

[0006] In addition, scanners specially used for scanning business cards have been proposed on the market, such as the business card scanning device disclosed in US Patent No. US5604640, which only provides the function of scanning one business card at a time, and because the casing of the business card scanning device Unlike traditional paper-fed scanners with openable housing structures, it is impossible to eliminate paper jams in the above-mentioned traditional paper-fed scanners. Therefore, there is a need for a business card that can be fed and scanned and that can be removed. sheet-fed scanner
