Abstract
The present invention relates to a curvilinear scanner including a main unit, a transmission mechanism, a curvilinear transmission shaft, a curviform document stand and an optical sensing module. During the scanning process, the optical sensing module conducts a curvilineal movement. Since the motion vector on the horizontal axis is shorter, it reduces the volume of the scanning device. By the curvilinear scanning way, it can scan an article with curve surface.
Claims20
A scanning device comprising:
- a main unit;
- a curviform document stand connected with the main unit and configured to hold a document to be scanned, wherein the document stand has a continuously curved scanning surface;
- and
- an optical sensing module driven by a transmission mechanism along a curved shaft generally corresponding to the continuously curved scanning surface for scanning the document.
1 more element
A scanner, comprising:
- a housing;
- a document support member carried by the housing, wherein the document support member has a generally arched, non-planar shape;
- and
- a scanning module positioned beneath the support member and driven along a transmission shaft having a curvature generally corresponding to the arched document support member, wherein the scanning module is configured to scan portions of a document positioned on the arched document support member.
1 more element
A scanner, comprising:
- a housing;
- means for supporting a document to be scanned, wherein the means for supporting includes a continuously curved support surface carried by the housing;
- and
- means for scanning the document through at least a portion of the continuously curved support surface, wherein the means for scanning includes a curved transmission shaft generally corresponding to the curved support surface.
