Abstract
Abstract A handheld scanner including a housing with a top head portion and a bottom handle portion with a contoured hand rest portion therebetween. A scanner trigger is located on the top of the top head portion which can be actuated either by a thumb or finger. The angular scanner structure, the trigger location, and the transparent scanning window enables the user to intuitively aim the scanner where the user's finger is aimed. The trigger centerline mark to aid in aiming the scanner at bar codes. A "V"-shaped aiming mark on top of the scanner head also aids in aiming the scanner. The angular shape of the scanner allows it to rest comfortably in the user's hand when being held, or alternately permit it to lie securely on a table without rocking when not being held yet still allow it to be easily picked up by the user.
