Portable large-scale drawing scanning device

Technical Field

The utility model relates to a photoelectric technology equipment field specifically is a portable large-scale drawing scanning device.

Background

Scanners (scanners) are devices that convert graphical or image information into digital signals in a scanning manner using electro-optical technology and digital processing technology.

Scanners are commonly used in computer peripheral devices by capturing images and converting them into digitized input devices that a computer can display, edit, store, and output. The scanner can be used for scanning three-dimensional objects such as photos, text pages, drawings, art pictures, photographic negatives, film films, even textiles, label panels, printed board samples and the like, and extracting and converting original lines, graphs, characters, photos and plane real objects into devices capable of being edited and added into files. The scanner belongs to the input system in Computer Aided Design (CAD), and forms a computer processing system before screen printing through computer software, a computer and an output device (a laser printer and a laser plotter) interface, so that the scanner is suitable for Office Automation (OA) and is widely applied to label panels, printed boards, printing industries and the like.
