Abstract
The present invention provides an image scanner comprising a housing having a transparent platform installed on it for placing a document, a calibrating area installed in the housing at a front end of the transparent platform, and a scanning module movably installed in the housing for scanning the document on the transparent platform. When performing a preview scan, the scanning module at a front end of the housing will move backward to scan the calibrating area to calibrate the scanning module and then scan the document on the transparent platform. When performing a formal scan, the scanning module that is stopped at a rear end of the housing will move forward to scan the document and stop at the front end of the housing.

An image scanner comprising:
- a housing having a transparent platform installed on it for placing a document;
- a calibrating area installed in the housing at a front end of the transparent platform;
- and
- a scanning module movably installed in the housing for scanning the document on the transparent platform;
- wherein when performing a preview scan, the scanning module at a front end of the housing will move backward to scan the calibrating area to calibrate the scanning module and then scan the document on the transparent platform, and when performing a formal scan, the scanning module stopped at a rear end of the housing will move forward to scan the document and stop at the front end of the housing.
A scanning method of an image scanner which comprises:
- a housing having a transparent platform installed on it for placing a document;
- a calibrating area installed in the housing at a front end of the transparent platform;
- and
- a scanning module movably installed in the housing for scanning the document on the transparent platform;
- the scanning method comprising:
- moving the scanning module backward from a front end of the housing to scan the calibrating area to calibrate the scanning module and then scan the document on the transparent platform to perform a preview scan;
- and
