Abstract

The invention is a kind of retractable scanner, which applies to scan files of different size, the scanner is made up of the first shell, the second shell, a fixing board, a rolling device, a transparent thin board and a scanning model. The second shell has two side boards and a bottom board, all the side board and the bottom are connected to the first shell with shaft, and they are suitable rotate to the surface of the first shell, obtains the aim that decreases the scanner size. The fixing board is connected to the first shell or the second shell with demountable mode. The rolling device is configured in the first shell, the transparent thin board is rolled in the rolling device, and the transparent thin board is suitable to be extracted out form the rolling device and connected to the fixing board. The scanning model is configured in the first shell, and the model is suitable to move flatly and in reverse under the transparent thin board.

Description

technical field [0001] The present invention relates to a scanner, and more particularly to a scanner with telescoping function for scanning documents of different sizes. Background technique [0002] With the substantial improvement of computer performance, and the high development of Internet and multimedia technology, in addition to using digital cameras (Digital Camera, DC) to directly capture image patterns, other image input operations related to documents or pictures require optical scanning. Optical Scanner to capture analog images of text or patterns and convert them into digital signal output, which helps users display, identify, edit, store and output image files on computers or other electronic products action. [0003] According to the input method of document images, optical scanners can be divided into hand scanners, sheet feed scanners, drum scanners and flatbed scanners ( Flatbed Scanner) and so on. It is worth noting that since the flatbed scanner has a ...

Problems solved by technology

[0005] However, commonly used scanners are all in a single size (usually suitable for scanning A4 paper), which is bulky and extremely inconvenient to carry. If the size of the scanner is reduced, it is easy to carry and can scan business cards or photos. Such as small-sized documents, but large-sized documents cannot be scanned. In this way, the overall functions of commonly used scanners will be limited, resulting in poor practicability
