Problems solved by technology

The current double-sided scanning device uses a whiteboard as the basis for the brightness correction of the image scanning module and also as the scanning background when the image scanning module scans the image. However, the edge of the object is usually white, so it is impossible to distinguish the object image from the scanned image. Scanning the background makes it difficult to crop out an image of the object that is consistent with the actual size of the object

Abstract

A dual-face scanning device includes a first image scanning module, a second image scanning module, a first scanning background assembly, a first luminance correcting assembly, a second scanning background assembly, and a second luminance correcting assembly; when the second image scanning module moves to a scanning position with respect to the first image scanning module, the second image scanning module can drive the first scanning background module to move with respect to the first image scanning module, the first scanning background assembly and the second scanning background assembly are aligned with the first image scanning module and the second image scanning module respectively, and use as scanning backgrounds of the first image scanning module and the second scanning module respectively, and then an object image matching the actual size of an object is cut.

Description

technical field [0001] The invention relates to a double-sided scanning device and a business machine, in particular to a double-sided scanning device and a business machine with a brightness correction component and a scanning background component. Background technique [0002] Thanks to digital technology, business machines (such as scanners or copiers, etc.) have been widely used in today's life to improve work efficiency. Generally speaking, a business machine with double-sided scanning function includes an automatic feeder and a double-sided scanning device. When the user wants to scan the opposite sides of the object at the same time, the automatic feeder can drive the object to be scanned (such as paper) Through the double-sided scanning device, to achieve the purpose of double-sided scanning. The current double-sided scanning device uses a whiteboard as the basis for the brightness correction of the image scanning module and also as the scanning background when the ...
