Two-page high-speed scanner with multiple sizes of formats

Abstract

The invention discloses a two-page high-speed scanner with multiple sizes of formats. The scanner is characterized by comprising a stand, two scanning assemblies, a light source and a composite scanning data bracket assembly, wherein the two scanning assemblies are arranged on the stand and comprise one fixed large-format scanning assembly and one movable small-format scanning assembly. The large-format scanning assembly comprises two groups of scanning element units which are fixed on the stand. The small-format scanning assembly comprises two movable parts and two format type scanning units, wherein the movable parts can synchronously move, and the format type scanning units are respectively arranged on the movable parts. The composite scanning data bracket assembly is arranged under the two scanning assemblies and comprises a V-shaped data bracket, a V-shaped transparent press plate and a lifting part, wherein the V-shaped transparent press plate can be pressed on the data bracket; the lifting part can drive the data bracket to lift and comprises a main bracket lifting part and a movable V-shaped lifting part. The invention can carry out two-page synchronous scanning on multiple sizes of newspapers and magazines and has the advantages of high scanning quality and high speed.

Description

technical field [0001] The invention relates to a scanner, in particular to a double-page high-speed scanner with multiple specifications. Background technique [0002] With the development of science and technology, scanners have become a necessary auxiliary tool for enterprises and institutions in office work, drawing, or paper data preservation. Especially for a large number of newspapers and books in libraries and archives, including some collected historical newspapers and books, in order to preserve the integrity of the materials, they are generally scanned into electronic files for readers to read. At present, the scanners used in libraries and archives to scan newspapers are generally imported linear scanners. Although they can scan large-format materials, there are the following problems: [0003] 1. The scanning speed is slow and the scanner is expensive. [0004] 2. In particular, this type of scanner adopts a single scanning method. Among them, large-scale pape...

AI Technical Summary

Problems solved by technology

[0003] 1. The scanning speed is slow and the scanner is expensive

[0004] 2. In particular, this type of scanner adopts a single scanning method, among which large-scale paper-feeding scanners are not suitable for scanning bound materials; small-scale book scanning can only be scanned with zero-margin linear scanners

If a double-page book scanner is used, it cannot be directly used for scanning large-format bound newspapers and periodicals due to the limited scanning format

At present, there is no multi-format scanner suitable for all kinds of books and archives

[0005] 3. The document bracket adopts a flat plate, and the bound newspapers and books must be disassembled before scanning, which increases the trouble for the operator
