Abstract:
A dust-proof mechanism for an optical reflection module of an image scanner for isolating dust from passing through an open area of the optical reflection module and attaching to a reflection mirror mounted in the optical reflection module, the dust-proof mechanism comprising:a dust-proof plate disposed at the open area of the optical reflection module;a driving unit for generating a driving force; anda transmission member connected between the driving unit and the dust-proof plate for transmitting the driving force generated by the driving unit to the dust-proof plate;wherein the dust-proof plate shields the open area of the optical reflection module when the scanner does not perform scanning operation, while when the scanner performs the scanning operation, the dust-proof plate is positioned at an opened position wherein the dust-proof plate is provided with two shaft rods pivotally mounted on the optical reflection module, the dust-proof being parallel to the mirror of the optical reflection module.
