Background

In order to repeatedly record and edit paper and other materials, the paper and other materials are generally scanned by a scanner, stored in a computer, and then edited. The data bracket in the common scanner has a good scanning effect on single-thin flat data, but for thick books, font deformation is easily generated between double pages of the books during scanning, so that the recognition effect of a computer host is influenced, and the subsequent editing work is difficult. In order to solve the problem, a scanner specially used for scanning books has been designed, which uses a planar sensor assembly to capture information of the books, and designs a book scanning bracket assembly in a V-shape to match the shape of the opened books. However, the existing book scanning bracket assemblies are only composed of a V-shaped transparent scanning platen and a rigid V-shaped plate, and although the deformation of the characters of the double-page scanning of the book can be reduced, the book scanning bracket assemblies still have the following disadvantages due to the structure:

1. when scanning and turning pages, a user lifts the V-shaped light-transmitting scanning pressing plate and turns pages, so that the structure can be only applied to scanning occasions of small book data. In the scanning occasion of large-format book data, if the V-shaped light-transmitting scanning pressing plate is lifted manually, the operation difficulty is brought;

2. the book scanning bracket assembly only comprises a V-shaped transparent scanning pressing plate and a hard V-shaped plate, when in use, a book to be scanned is directly placed on the V-shaped plate, and the V-shaped transparent scanning pressing plate is pressed upwards. If the thickness of the two sides of the book to be scanned is greatly different after the book to be scanned is turned over, the pressed V-shaped light-transmitting scanning pressing plate can incline to one side, and the scanning quality can be influenced.

3. By adopting the bracket type structure, the scanning light source with high scanning intensity directly influences the watching of an operator during working, and the operator directly operates in the scanning space, thus the labor intensity is high.
