The LBS is a book scanner for use in a library. People usually go to the library to search for information to write their report, and they still use the traditional way, hard copy, to take the information home. Later on, almost everyone writes the report using a computer. If we are going to use a computer in the final stage, why don’t we get the digital data directly from the book without the hard copy process? This would be much more convenient for the user. The LBS has two scan modules, which are positioned in a 90 degree angle at the edge of the table and work simultaneously, making the process even faster. Therefore, the user just needs to place the book face down on the LBS to get digital data immediately. This way, users can take digital data with them via a USB flash drive, PDA, or notebook.
