  • Patent number: 5739744
    Abstract: A thin, portable, lightweight electronic name and address cardfile optionally including memo alarm, calendar and calculator functions, is provided with a contact and movement sensitive scrolling mechanism for sequentially advancing electronically simulated name and address cards in the style of bottom-attachable index cards. The scrolling function is accomplished by manipulating a graphic representation of a rotary actuator of the type provided on a mechanical rotary-type directory. The simulated card-flipping is accompanied by an artificial sound effect reminiscent of the expected sound of cards flipping. The device may be provided with holes positioned so as to render the device insertable within a loose-leaf ring-type binder notebook or personal organizer.
