Abstract

A scanning apparatus capable of locating a scanning starting point. The scanning apparatus includes a housing, a carriage, and a calibration paper. The housing includes a scanning platen for supporting a document to be scanned. The calibration paper is mounted on the scanning platen, adjoins one of the shorter sides of the scanning platen, and has a marked area. The marked area is defined by a set of functions and includes the scanning starting point for indicating users to locate the document to be scanned on the scanning platen according to the scanning starting point. When the carriage is moved to a scanning line, the carriage locates the scanning starting point according to the intersections of the marked area being scanned and the scanning line, and the set of functions defining the marked area.

Dependent claims

A scanning apparatus capable of locating a scanning starting point, comprising:

a housing comprising a scanning platen for supporting a document to be scanned;
a carriage placed under the scanning platen for scanning objects on the scanning platen;
and
a calibration paper mounted on the scanning platen and adjoining one of the shorter sides of the scanning platen, the calibration paper having a marked area defined by a set of functions, the marked area including the scanning starting point for indicating users to locate the document to be scanned on the scanning platen according to the scanning starting point;
wherein when the carriage is moved to a scanning line intersecting with the marked area, obtaining intersections of the carriage and the scanning line, the carriage locates the scanning starting point according to the intersections and the set of functions defining the marked area.
