Scanning apparatus with calibrating function

摘要

A sheet-feeding type scanning apparatus with a calibrating function is provided. The sheet-feeding type scanning apparatus is configured for feeding a document in a first direction and scanning the document, thereby acquiring an image of the document. The sheet-feeding type scanning apparatus includes a calibration plate, a scanning module, and a transmission module. The transmission module is connected with the scanning module for moving the scanning module in a second direction perpendicular to the first direction. In such way, the scanning module is movable within the limited space of the sheet-feeding type scanning apparatus, so that the scanning module is dynamically calibrated.

1. A sheet-feeding type scanning apparatus with a calibrating function, said sheet-feeding type scanning apparatus being configured for feeding a document, moving said document in a first direction and reading an image of said document, said sheet-feeding type scanning apparatus comprising:
a sheet transfer channel for allowing said document to go through; a scanning module disposed in said sheet transfer channel for scanning a first side of said document, thereby acquiring a first side image of said document; a calibration plate disposed over said scanning module, wherein said scanning module is calibrated according to said calibration plate; and a transmission module connected with said scanning module for moving said scanning module in a second direction perpendicular to said first direction, so that said scanning module is calibrated while said scanning module is moved, wherein said transmission module comprises:
a push gear located at a first side of said scanning module, wherein upon rotation of said push gear, said scanning module is moved in said second direction; andan elastic element located at a second side of said scanning module for providing an elastic force to said scanning module, wherein in response to said elastic force, said scanning module is moved in a third direction opposite to said second direction and returned to an original position.
