Books and manuscripts, as a carrier of civilization and a precious record of human culture, are therefore invaluable cultural and artistic values. The establishment of the Library of Alexandria in Egypt became the center of civilization in the early days of mankind. This is the world's first database of human civilization results, and is also a university. In the most prosperous period, the library had a collection of 900,000 volumes, which was the most library in the world with the largest collection of books, the largest number of languages, and the most comprehensive bibliographic records.
However, as time goes by, these valuable materials, which play a major role in the inheritance of human culture, have suffered from paper aging corrosion and storage environment in the long river of time. Doing your best to preserve these precious cultural heritages is an important part of libraries, archives and museums. The number of games has been serving the field of digital-to-analog conversion storage systems for more than 50 years, with librarians and archive librarians around the world who trust the digital-to-digital integration and the security and superior technology of file digital devices.

Compared to other common scanners, the number of books and magazines has excellent performance, outstanding features and advantages.
1. Linear non-contact CCD scanning method:
At present, mainstream book scanners mainly use two scanning methods:
Linear CCD scanning and matrix scanning (commonly known as surface scanning) The main difference between the two scanning methods is that linear CCD scanning uses progressive scanning to scan, the details and clarity of the image are consistent, but the scanning speed is relatively slow; The matrix type CCD has a fast scanning speed, and the scanning time is usually one-fifth of that of a linear CCD scanner, but the scanning image has poor definition and severe deformation. Linear CCD scanning technology is undoubtedly the first choice for ancient books that have great scientific value and require very high definition.
2. Under the premise of ensuring image quality, the scanning efficiency is high:
At present, the number of devices in the linear CCD scanning technology, under the premise of effectively guaranteeing the scanning quality, the scanning speed is the fastest.
3, support ICC Profile full color management
The ICC Profile is simply a description of the color characteristics of a color device. It shows the correspondence between the color description of this particular device and the standard color space. Therefore, the input and output of the image are better kept consistent, and the input and output devices maintain a consistent color standard, which provides strong support for post-image printout and simulation copying. For the digital work of ancient books, the true color of ancient books can be restored to a large extent.
4 automatic white balance function
The automatic white balance setting ensures that the series of scanners has an automatic white balance function, so that there is no chromatic aberration in the image obtained by each scan. At present, many scanning devices of the same type on the market do not have an automatic white balance function, resulting in a large color deviation of images obtained after two scans.
6, semi-automatic glass press device
The semi-automatic glass-pressing device can ensure that the ancient books are protected from external damage during scanning, and the foot switch and exposure switch equipped at the same time can minimize the workload of the staff.
7, can be lifted, separated type of desk
Different from other scanners on the market, the number of scanning devices is equipped with a lifting table, which can be lifted and lowered separately. Considering the characteristics of ancient book binding, the book table can be separated from left to right, thus the ancient books. Insert the spine into the line to avoid crushing the ancient books. In addition, the desk can be locked at any position.
8, from the back to the front of the scanning method
The scanning method from the back to the front ensures that the scanner does not exhibit its own light pollution during the scanning process. At present, some book scanners on the market adopt a left-to-right scanning mode, which inevitably causes the light source to interfere with the scanning head due to refraction when the two side light sources are irradiated to the center position.
9, unique dual scanning head technology
For the ancient books, the biggest feature is the irregularity of the size. The game number scanner uses a dual scanning head technology combining stereo and plane to superimpose the stereo image and the planar image, and then correct the deviation and correct the middle seam through the Perfectbook function.
As a result of the use of shockproof protection materials, coupled with special ergonomic design and unique reinforcement production technology, very solid and durable, popular. Laptop Document Bag in addition to a special shockproof computer protection layer, there is considerable space can be used for small items such as travel luggage. Many high quality shoulders backpack is also widely used as a sports travel bag. If you need go to business and study, the canvas backpack will be your best choosing. And also you could choose our other Sports Backpack.
