  • Patent number: 5049862
    Abstract: A keyboardless portable computer simulates a foldable notepad and has a display which can be reoriented to the convenience of the user, carried in a self-protecting closed position and operated in any convenient open position. The computer has a first flat panel, a second flat panel and hinge means for joining the first panel to the second panel such that the first flat surface is juxtaposed to the second flat surface in a closed position and is disposed side by side in a common plane in one of a selection of open positions. The first flat surface comprises a first digitizer and the second flat surface comprises a second digitizer, and a stylus is provided which is connectable to at least one of the panels for interacting with at least one of the digitizers. One of the digitizers includes a flat panel display through which visual output is provided. Thus, registration of a written symbol on the surface of the panel produces a displayed symbol, preferably at the position of registration.
