Multifunctional computer printing scanner

The invention discloses a multifunctional computer printing scanner, relates to the technical field of computer printing scanners, and solves the problems that when a computer printing scanner is used, data paper subjected to double-sided scanning needs to be manually positioned and overturned, the printing scanner needs to be repeatedly opened, the operation is complex, and the efficiency is low. A multifunctional computer printing scanner comprises a printing scanner body, a rotary cover plate is arranged above the printing scanner body, a data insertion opening is formed in one end of the printing scanner body, and a data extraction plate is movably arranged below the data insertion opening. And two conveying belt mechanisms which are symmetrically distributed up and down are arranged in the middle of the data insertion port. Compared with the prior art, data paper with a scanned single face can be directly overturned, secondary positioning of the paper is not needed after overturning, repeated positioning
