Abstract

The invention relates to one book scanner with contracted scanning distance to scan one book with one first and second inner sides and one binding line. The scanner comprises one book supportive structure and one scanning module; the book supportive structure has one first part and second part with first angle and one prism line less than 180 degrees. The scanning module is to scan the first inner side with the first part.

Description

technical field [0001] The invention relates to a book scanner with shortened scanning margins, in particular to a book scanner with zero scanning margins. Background technique [0002] Traditional book scanners can be divided into two types according to the moving direction of the scanning module and the direction of the binding line of the book, one of which is that the moving direction of the scanning module is parallel to the direction of the binding line of the book, and the other is the moving direction of the scanning module Perpendicular to the direction of the book binding. The book scanners that the present invention focuses on are both. [0003] In order to scan open books (including bound documents), the book scanner usually has a beveled side and a transparent platform to support the open book, so as to obtain better scanning quality. [0004] In order to capture images close to the binding line, in addition to overcoming the lack and unevenness of the light s...

Problems solved by technology

As a result, images close to the gutter cannot be captured, or the captured quality is quite poor

For some very thick books, because they cannot be fully opened, the image data near the binding line cannot be captured by traditional book scanners, so there will be image distortion
