Description

Paper path switching mechanism of scanner Technical Field The utility model relates to the technical field of scanners, in particular to a paper path switching mechanism of a scanner. Background The automatic printing mark is that the homework or the examination paper of the student is electronized through the scanner, the electronized homework or examination paper is subjected to data comparison operation through the operation module, and finally, the operation result is printed on the homework or examination paper through the printer, so that the workload of a teacher for correcting the examination paper is reduced, and the read mark can be left on the original paper, thereby being convenient for the explanation of the subsequent teacher and the review of the student. The existing automatic printing mark-remaining system mainly scans a file through a scanner, then the file is conveyed to a printer through a transfer channel, and finally the printer prints according to an operation result. In order to increase the independent scanning function, a paper outlet channel can be added on a scanner of the printing mark-remaining system, so that a user can conveniently and independently use the scanning function. However, when the user switches the scanning mode and the scanning printing mode, how to freely switch the paper path, so that the scanning channel is communicated with the paper outlet channel or the transfer channel, which is an urgent problem to be solved at present. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide the scanner paper path switching mechanism capable of freely switching paper paths according to requirements.
