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.
