SCANNER MODULE AND IMAGE SCANNING APPARATUS EMPLOYING THE SAME
First Claim
1. An illuminator for use in an image scanning apparatus to illuminate light on an object to be scanned, comprising:
- a light emitting diode configured to produce the light;
a light guide having an elongated shape with its length extending along a first direction, the light guide being configured to receive the light from the light emitting diode, and to change a direction of the received light;
a light source holder to mount the light emitting diode to the light guide; and
at least one elastic member elastically supporting at least one of longitudinal ends of the light guide.

Abstract
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.
