Scanner module and image scanning apparatus employing the same

An illuminator for use in an image scanning apparatus to illuminate light on an object to be scanned, comprising:na 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; andat least one supporting protrusion, formed at the guide holder, protruding into the mounting recess in order to support a part of the light guide in at least a second direction perpendicular to the first direction,wherein the light guide comprises:nan emission face through which the light is emitted from the light guide,a pair of guide faces formed at both longitudinal sides of light guide, anda reflect face opposite the emission face of the light guide to reflect the light,wherein the at least one supporting protrusion having a plurality of supporting protrusions to support the pair of guide faces and the reflect face respectively.

A scanning module for use in an image scanning apparatus for scanning an object, comprising:nan illuminator configured to illuminate a light on the object to be scanned; anda sensor configured to detect the light reflected from the object,wherein the illuminator comprises:na 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; andat least one supporting protrusion formed at the guide holder, protruding into the mounting recess in order to a part of the light guide and restrict movement of the light guide in at least a second direction perpendicular to the first direction,wherein the light guide comprises:nan emission face through which the light is emitted from the light guide,a pair of guide faces formed at both longitudinal sides of light guide, anda reflect face opposite the emission face of the light guide to reflect the light,wherein the at least one supporting protrusion having a plurality of supporting protrusions to support the pair of guide faces and the reflect face respectively.

An image scanning apparatus, comprising:na scanner module; anda controller configured to control an operation of the scanner module,wherein the scanner module comprises:nan illuminator configured to illuminate a light on an object to be scanned; anda sensor configured to detect the light reflected from the object,wherein the illuminator comprises:na 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;a guide holder having formed thereon a mounting recess into which the light guide is received; andat 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,wherein the light guide comprises:nan emission face through which the light is emitted from the light guide,a pair of guide faces formed at both longitudinal sides of the light guide, anda reflect face opposite the emission face of the light guide to reflect the light,wherein the at least one supporting protrusion having a plurality of supporting protrusions to support the pair of guide faces and the reflect face respectively.
