Scanner module and image scanning apparatus employing the same

A scanning module for use in an image scanning apparatus for scanning an object, comprising:

• an illuminator configured to illuminate a light on the 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 emit 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;
• a guide holder having formed thereon a mounting recess into which the light guide is received;
• and
• at least one supporting protrusion, formed at the guide holder, protruding into the mounting recess in order to support a part of the light guide and restrict movement of the light guide in at least a second direction perpendicular to the first direction.

An image scanning apparatus, comprising:

• a scanner module;
• and
• a controller configured to control an operation of the 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:
• a light source configured to emit 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;
• a guide holder having formed thereon a mounting recess into which the light guide is received;
• and
