  • Mobile pen computer having an integrated palm rest
    Patent number: 5657258
    Abstract: A pen computer has a double hinge connector and a first member which is rotatably connected to the connector. The first member has a pen sensitive screen. A second member, having a flat surface, is also rotatably connected to the connector. The pen computer is in a closed position when an angle between the first and second members is equal to zero degrees. The pen computer is in an open position when the angle between the first and second members is substantially equal to 180 degrees. When the pen computer is in the open position, the flat surface of the second member is substantially level with the pen sensitive screen of the first member, such that the flat surface is operable as a palm rest for facilitating the use of the pen sensitive screen.
