Scanner module and image scanning apparatus employing the same

摘要

A scanner module and an image scanning apparatus employing the same. The scanner module comprises an illuminator for illuminating light on an object to be scanned. The illuminator includes a light emitting diode, a light guide extending in a main scanning direction to change a direction of the light received from the light emitting diode, and at least one elastic member to elastically support at least one longitudinal end of the light guide. As the light guide is elastically supported by the elastic member, convex deformation or bowing of an emission face of the light guide due to thermal expansion can be reduced.

主权项

1. A light guide unit for an image forming apparatus, the light guide unit comprising:
a light guide configured to receive a light from at least one light source, and to change a direction of the received light; at least one elastic member configured to support at least one part of the light guide; a light guide mounting portion including at least one spacer, the light guide mounting portion configured to mount the light guide so the at least one part of the mounted light guide is elastically supported by the at least one elastic member and at least one part of the mounted light guide is supported by the at least one spacer; and a holder capable of mounting the at least one light source to the light guide.
