Abstract
A hand-held image scanner according to this invention comprises a light source, a transparent cover through which a light emitted from the light source passes to illuminate a script, and an optical system into which light reflected from the script is input, wherein the transparent cover is integrally comprised of a light gathering lens and a transparent area. Additionally, the transparent cover is bent in such a manner as to minimize the angles of incidence of light passing through the light gathering lens and the transparent area.
