Problems solved by technology

The scanner mainly uses the internal image to capture the graphics, images, and text of the document, and converts it into a digital signal and then sends it to the computer for processing. The scanning head of the traditional double-drum scanner is located at the bottom of the scanner, so when scanning The scanning surface of the paper is punched down, which is not convenient for the user to operate. When the scanning head is placed on the upper part of the scanner, the user can intuitively see the scanning surface of the scanning medium, so a new transmission device needs to be proposed

Abstract

The invention discloses a transmission device of a scanner. The transmission device comprises a scanner shell. A synchronous wheel is arranged in the scanner shell. The synchronous wheel is cooperated and connected with a first driving wheel and a second driving wheel. The second driving wheel is cooperated and connected with a driven wheel. The driven wheel is arranged between the first driving wheel and the second driving wheel. A first roller and a second roller are respectively arranged on the first driving wheel and the second driving wheel. A pressure roller is arranged on the first roller and the second roller. By using the transmission device of the invention, more accurate scanning image can be acquired. Operation is convenient.

Description

technical field [0001] The invention relates to the field of scanners, in particular to a transmission device of a scanner. Background technique [0002] With the development of digital image technology, scanners have become a common computer interface device, and even built-in scanners in multi-function business machines provide document functions. The scanner mainly uses the internal image to capture the graphics, images, and text of the document, and converts it into a digital signal and then sends it to the computer for processing. The scanning head of the traditional double-drum scanner is located at the bottom of the scanner, so when scanning The scanning surface of the paper is punched down, which is not convenient for the user to operate. When the scanning head is placed on the upper part of the scanner, the user can directly see the scanning surface of the scanning medium. Therefore, a new transmission device needs to be proposed. Contents of the invention [000...
