Book scanning instrument with homogeneous light source structure

Abstract

The book scanner includes one main body with glass window, and one optical bench set inside the main body. The glass window set on the main body has angled structure for the scanned file to be set on, and the optical bench is provided with one bar light source corresponding to the glass window. Especially, the light source has its stronger light part far from the glass window and weaker light part near the glass window, so that the scan lines generated via irradiating the light source to the scanned matter have stable and homogeneous brightness.

Description

technical field [0001] The invention relates to a scanner light source structure and a scanner glass window structure, wherein the scanner mainly refers to a book scanner, and the glass window has an included angle structure so that two adjacent pages of a book can be flat when the book is opened. Attached to the surface of the glass window. As for the light source, it is a strip light source, and can move along the direction of the ridge line formed on the glass window of the folding angle structure, so as to provide the light required for scanning the book. Background technique [0002] The main components of a general scanner include a body, a glass window, an optical machine module and a light source. Wherein, the glass window is assembled on the top of the main body, and the optical-mechanical module is movably assembled in the main body, and the light source is assembled on the optical-mechanical module corresponding to the glass window...

Problems solved by technology

In other words, in the application of the book scanner 10, the image scanning is performed on the binding side 182 of the book 18 and its peripheral parts with the part where the light intensity of the light source 168 is weak and unstable, so it is predictable to scan The resulting image information will be prone to unclear or incorrect situations
