The present invention relates to a portable scanner and a data scanning method using the same.

In general, a scanner is a device that reads a form such as a picture or a character, and then transmits the result to a connected computer so that the result can be displayed on a monitor or stored in a computer. In this case, the characters read by the scanner are converted into information that can be processed by the computer by software that recognizes the characters on the computer. In this way, even if a scanner is used to scan a photograph or a document, a computer is indispensable for checking the result and performing the subsequent processing. Therefore, the conventional scanner is difficult to operate independently.

The conventional scanner uses a contact image sensor (CIS). The CIS is a compact image input device that scans an object adhering to a glass surface to produce data, and has a self-lens-based structure The thickness of the scanner is limited to several tens of mm or more.
