ABSTRACT:
A lid and lid drive mechanism for a portable, hand held device pivots a flat cover on the device in a predetermined controlled manner between a first position covering at least portion of the front of the device and a second position in which the cover extends towards the rear of the device. The drive mechanism comprises a spring/damper mechanism which pivots the cover of the device in a predetermined controlled manner between the first position and the second, thus forming a stand raising the top end of the device above a horizontal support surface upon which it rests. The top end of the device frame has left and right inwardly facing extension which enclose a first and second cylindrical hollow cavities. A coiled drive spring is located in one hollow cavity which a damping mechanism utilizing a damping drum and a viscous fluid is located in the second hollow cavity.
