Abstract
An optical scanning device with a dustproof function includes a shell defining a first receiving room and a second receiving room communicating with the first receiving room through an open window defined on the shell for scanning light beams passing therethrough. An optical scanning module is mounted in the first receiving room. A glass platform is located on the second receiving room at a position facing the open window for insulating the first receiving room from the outside of the shell. A correcting plate is stuck on the bottom of the glass platform. Such structure of the optical scanning device enables the glass platform to be firstly assembled with the shell in a dustless chamber, which prevents the suspending dust from falling in the first receiving room and attaching to the optical scanning module during the subsequent assembly process and ensures the scanning quality of the optical scanning device.
