  • Patent number: 5719936
    Abstract: A communication device for mobile operation is equipped with a telephone as well as with a notebook with a display. Prior art devices have a housing in "pocket format" and a practically unrestricted mobility only with a greatly restricted range of functions, for example the lack of an integrated telephone part. Further, the built-in computers are usually only designed as "notepads" without a keyboard. The communication device (1) for mobile operation has a telephone and a notebook with a touch-sensitive display (3) that is accommodated in a pocket-format device housing (3) composed of two sub-sections (9,10) connected to one another at a swivelling axis (8). The telephone and the display (3) are accommodated in one sub-section (10), whereas the other sub-section (9) holds an alphanumerical keyboard (14) accessible to the user.
