Abstract
The present invention provides a surface-reading apparatus that includes a subject-flexing mechanism and a surface-reading component. The subject-flexing mechanism causes a subject to flex in one of a convex form and a concave form. The surface-reading component reads a characteristic of a surface condition of the subject that has been flexed by the subject-flexing mechanism. The surface-reading component can includes an optical reading component that optically reads the characteristic of the surface condition of the subject. The optical reading component may be a reflected light-reading component that reads the characteristic of the surface condition of the subject with reflected light or may be a transmitted light-reading component that reads the characteristic of the surface condition of the subject with transmitted light.
