Abstract
A scanner capable of quickly finding a leading edge includes a scanning module for scanning a document, a moving mechanism for moving the scanning module, a non-volatile memory for storing leading edge position data, and a control processor. The control processor enables the scanning module to start to scan the document when the scanning module is moved by a leading edge distance corresponding to the leading edge position data and thus to obtain image data of the document. The leading edge position data is generated by scanning a standard template.

A scanner capable of quickly finding a leading edge, comprising:
- a scanning module for scanning a document;
- a moving mechanism for moving the scanning module;
- a non-volatile memory for storing leading edge position data;
- and
- a control processor for enabling the scanning module to start to scan the document when the scanning module is moved by a leading edge distance corresponding to the leading edge position data and thus to obtain image data of the document.
A method of finding a leading edge in a scanner, comprising the steps of:
- moving a standard template or a scanning module;
- counting a relative moving distance between the standard template and the scanning module;
- scanning the standard template to obtain image data of the standard template and an area outside the standard template to obtain reference image data;
- comparing the image data of the standard template with the reference image data to obtain the leading edge of the image data of the standard template and obtaining leading edge position data according to the relative moving distance and the leading edge;
- and
- storing the leading edge position data in a non-volatile memory.
A method of finding a leading edge in a scanner, comprising the steps of:
- loading leading edge position data stored in a non-volatile memory;
- moving a scanning module by a leading edge distance corresponding to the leading edge position data;
- and
- starting scanning a document to obtain image data of the document.
