A light pipe is mounted to a support structure along a length of the light pipe. The light pipe has an end at which light enters the light pipe. Light exits the light pipe at an emissive surface of the light pipe. A reflective backing is positioned at a surface of the light pipe opposite the emissive surface. A compliant member between the reflective backing and the support structure maintains the reflective backing flush against the surface of the light pipe.

Scanning device light guide assembly having compliant member

An example image scanning apparatus includes a lighting unit to irradiate light onto a manuscript using an LED light source, a scan unit to generate a scan image by scanning image information of manuscript using light reflected by the manuscript, and a processor to control the lighting unit to irradiate light on each unit pixel by a predetermined duty during a movement process of the manuscript in a sub-scan direction.
