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.
Claims16
A scanner module for use in an image scanning apparatus to scan an object, comprising:
- at least one light source configured to produce the light;
- at least one 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 source, and to change a direction of the received light;
- at least one light source holder to mount the at least one light source to the at least one light guide;
- and
- at least one heat radiating member including a portion in contact with the light source to dissipate heat generated from the light source.
An image scanning apparatus, comprising:
- a scanner module,
- wherein the scanner module comprises:
- an illuminator configured to illuminate a light on an object to be scanned;
- and
- a sensor configured to detect the light reflected from the object,
- wherein the illuminator comprises:
- at least one light source configured to produce the light;
- at least one 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 source, and to change a direction of the received light;
- at least one light source holder to mount the at least one light source to the at least one light guide;
- and
- at least one heat radiating member including a portion in contact with the light source to dissipate heat generated from the light source.
