Scanner module and image scanning apparatus employing the same

摘要

A scanner module and an image scanning apparatus employing the same include a light source to generate light, a light guide member to guide the light toward an object, a sensor configured to detect the light reflected by the object, at least one reflecting mirror to reflect the light reflected by the object to the sensor, and a focusing lens to focus the reflected light redirected by the at least one reflecting mirror on the sensor. The light guiding member includes an incident surface to receive the light, a reflective surface to reflect the light received through the incident surface, a plurality of guide surfaces to guide the light received through the incident surface, and an exit surface to allow light reflected by the reflective surface to exit. An interval between reflective linear elements increases from a center of the light guide member towards the incident surface.

主权项

1. A scanner module movably mounted below a document bed comprising:
a light source to generate light to be irradiated onto an object; a light guide member to guide the light generated from the light source toward the object; a sensor configured to detect the light reflected by the object; at least one reflecting mirror to reflect the light reflected by the object in a horizontal direction to guide the light to the sensor; and a focusing lens disposed between the at least one reflecting mirror and the sensor to focus the reflected light redirected by the at least one reflecting mirror on the sensor, and wherein the light guide member comprises:
an incident surface through which the light generated by the light source is received;a reflective surface provided with a plurality of reflective linear elements extending in a widthwise direction of the reflective surface to reflect the light received through the incident surface;a plurality of guide surfaces to guide the light received through the incident surface; andan exit surface opposite to the reflective surface to allow light reflected by the reflective surface to exit, wherein the reflective surface is defined by a plurality of first reflective grooves and a plurality of second reflective grooves and, wherein an inclination angle of the first and second reflective grooves with respect to the widthwise direction of the light guide member are gradually increased from a center to both longitudinal ends of the light guide member.
