An enhanced reading device which secures written material in a fixed location, and moves a video camera across the written text or images for the purpose of automatically registering the video camera at the beginning of each new line. The device uses a manually operated transmission to move the video camera across a line at a speed controlled by the user. The video camera is also stepped to the next line under control of the user. Optional embodiments permit the transmission to be powered and control by push buttons for automatic registration at the beginning of new lines. The device also has a document tray assembly to control vertical movement of the document in relation to the video camera under control of the user. The document tray assembly can also be optionally powered rather than manually operated.
