Abstract:
1. A detachable document-holding-device for holding a document at a substantially fixated distance from a lens ( 20 ) disposed at a back surface ( 12 ) of a portable imaging apparatus, the lens having an optical axis, the document-holding-device ( 100 ) comprising: (a) a document-tray ( (b) a sliding interface ( (c) a mounting-structure ( (d) a base ( (e) an attachment/detachment configuration, wherein said base ( 140 ) is securely attached to said back surface ( 12 ) of said portable imaging apparatus; wherein said attachment/detachment configuration is adapted to attach said attachment panel ( 134 ) to said base ( 140 ), and wherein said mounting-structure ( 130 ) is operatively mounted onto said base ( 140 ); wherein said document-tray ( 110 ) and said sliding interface ( 120 ) are pivotally interconnected, wherein said pivotal motion is facilitated by a second cylindrical shaft ( 155 ); wherein said hollow passage ( 122 ) is preconfigured to fittingly accommodate said sliding panel ( 132 ), facilitating said sliding panel ( 132 ) to slide through said hollow passage ( 122 ), when moved by the user, to thereby set the distance between said document-tray ( 110 ) and the lens; wherein when in operational state, said document-tray ( 110 ) is substantially perpendicular to said optical axis of the lens, and wherein said upper surface ( 112 ) of said document-tray ( 110 ) is facing the lens; and wherein an optical path, having a fixated optical distance, is formed such that when a document ( 30 ) is placed onto said upper surface ( 112 ) of said document-tray ( 110 ), an image of said document ( 30 ) is reflected towards the lens of said portable imaging apparatus.
