Therefore, scanners have become very popular not only for public use, but also for the home.

1. Sliding head. It resembles a sliding ruler and is located slightly above the image. During scanning, it smoothly moves from the beginning of the sheet to the end.
2. Book cradle. She can often be found on these models. In other versions, the cradle is made in the form of a pressure glass. But book scanners have a V-shaped cradle. It is needed to perfectly align the book and its size.
3. Matrices, they can also be found in digital cameras. They help speed up the scanning process. This is due to the rapid opening of the shutter. At this time, the matrix transforms the light image into an analog electrical signal.
