ABSTRACT:
A supporting mechanism for scanning module comprises a supporting bracket for mounting a scanning module thereof Two end portions of the top surface of the supporting bracket are provided with a roller respectively. When the supporting bracket moves longitudinally, the rollers rolls along a bottom surface of a glass plate when a biasing force is exerted to the supporting bracket. The supporting mechanism further includes a biasing device moveably supported by a supporting runway at one end. The biasing device provides a horizontal and a vertical biasing force to the supporting bracket respectively. The supporting bracket is in close contact with a longitudinal reference surface due to the horizontal biasing force exerted thereon as the supporting bracket moves longitudinally. The clearance between the scanning module and the bottom surface of the glass plate is kept substantial constant by the vertical biasing force exerted to the supporting bracket when it moves longitudinally.
