Abstract: A hand-held scanning device is disclosed in which the scanning device housing window has a recessed optical portion of the window formed such that the recessed optical portion of the window does not come into contact with the object being scanned while a scan is being performed. This recessed optical portion of the window eliminates damage caused by contact with the object being scanned to the optical portion of the window. The recessed portion of the window is formed without corners in such a manner that it may easily be wiped clean by the end user without dirt, dust and the like building up in corners of the recess. The recessed portion of the window is also formed in such a manner as to maintain the object in a relatively flat position under the scan window throughout the scanning process.

Abstract: An image sensor module includes a light source unit that emits a linear light beam elongate in a primary scanning direction to an object to be read, and a lens unit including an incidence surface and an output surface oriented opposite to each other. The lens unit is configured to receive light from the object through the incidence surface and output the light through the output surface. The module also includes a sensor IC that receives the light outputted from the output surface, a housing that holds the light source unit and the lens unit, and a support member that supports the lens unit such that the incidence surface is located more distant from the sensor IC than the output surface in a secondary scanning direction. The support member includes a reflection surface that reflects the light from the object toward the incidence surface.
