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.
Claims17
A scanner module for use in an image scanning apparatus to scan an object, comprising:
- a light source configured to produce light emitted by the scanner module to scan the object;
- and
- a heat radiating member made of an elastically deformable material to cause the light source to come into close contact with the heat radiating member and configured to dissipate heat generated from the light source when the light source produces the light.
An image scanning apparatus, comprising:
- a scanner module,
- wherein the scanner module comprises:
- an illuminator configured to illuminate light on an object to be scanned;
- and
- a sensor configured to detect the light reflected from the object,
- wherein the illuminator comprises:
- a light source configured to produce the light illuminated on the object to scan the object;
- and
- a heat radiating member to dissipate heat generated from the light source when the light source produces the light, the heat radiating member being made of an elastically deformable material.
A scanner module for use in an image scanning apparatus to scan an object, comprising:
- a light source configured to produce light;
- a heat radiating member configured to dissipate heat generated from the light source;
- and
- 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 source, and to change a direction of the received light,
- wherein the heat radiating member is in contact with the light source.
An image scanning apparatus, comprising:
- a scanner module,
- wherein the scanner module comprises:
- an illuminator configured to illuminate light on an object to be scanned;
- and
- a sensor configured to detect the light reflected from the object,
- wherein the illuminator comprises:
- a light source 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 source, and to change a direction of the received light;
- and
- a heat radiating member to dissipate heat generated from the light source, and
- wherein the heat radiating member is in contact with light source.
