Document scanner convenient for adjustment

Abstract

The invention relates to the technical field of a document scanner and particularly relates to a document scanner convenient for adjustment. The document scanner comprises a chassis, wherein a fixingpost is fixedly connected with the side face on the top of the chassis; a lifting rod is inserted into the top of the fixing post; a fixing frame is fixedly connected with the top of the lifting rod;a slide sleeve is in slide connection with the outer surface of the fixing frame; an electric appliance box is fixedly connected with the bottom of the slide sleeve; a light supplement lamp and a scancamera are fixedly connected with the bottom of the electric appliance box; an iron rod is fixedly connected with the bottom of the inner cavity of the fixing post; a fixing plate is fixedly connected with the bottom of the end of the lifting rod located in the inner cavity of the fixing post; a magnetic rod is inserted into the top of the fixing rod at the side away from paper; and the end of the magnetic rod located in the inner cavity of the fixing post penetrates the lifting rod and is inserted into the side face of the iron rod. According to the document scanner, the magnetic rod is separated away from the lifting rod and the iron rod by pulling a pull handle, the lifting rod is lifted or pushed down, the height of the scan camera can be adjusted conveniently, and the paper scan precision is improved.

Description

technical field [0001] The invention relates to the technical field of document scanners, in particular to an easily adjustable document scanner. Background technique [0002] A document scanner is a portable, low-carbon and environmentally friendly high-speed document scanning device. It is mainly used to scan documents. It can record our paper documents in one second and scan pictures through The OCR text recognition function quickly converts editable documents, thereby greatly improving office efficiency. [0003] In the process of converting a paper document into an editable document, a document scanner is needed to parse the document into an electronic document, but the existing document scanner generally places the document paper on the chassis during the scanning process of the document for easy scanning. The text on the paper is scanned, but for documents with large or small paper length or width, during the scanning process, because the height of the scanner is fix...
