1. In the field of compact, portable, lightweight, electronic information-processing devices suitable for storage and retrieval of information such as names, addresses, telephone numbers and personal memoranda, a simulated rotary-type directory operated by sliding contact along a visually simulated mechanical rotary actuator, comprising:

  • a thin enclosure containing upon an external face thereofa substantially rectangular LCD screen for presenting simulated directory index cards in the style of bottom-attachable rotary-type cards; and

    an alphanumeric keyboard for entering characters to be displayed upon said simulated cards;

    a simulated rotary actuator for controlling sequential advancement of said simulated cards in a first direction corresponding with simulated clockwise sequential advancement of said simulated cards and for controlling sequential advancement of said simulated cards in a second direction corresponding with simulated counterclockwise sequential advancement of said simulated cards, said simulated rotary actuator being responsive to the direction and rate of movement of a user'"'"'s thumb or another user-controlled contactor device such that a sliding movement of said user-controlled contactor device in a first direction along said simulated rotary actuator effects said simulated clockwise sequential advancement of said simulated cards at a rate which corresponds with said rate of movement of said user-controlled contactor device in said first direction and such that a sliding movement of said user-controlled contactor device along said simulated rotary actuator in a second direction opposite to said first direction effects said simulated counterclockwise sequential advancement of said simulated cards at a rate which corresponds with said rate of movement of said user-controlled contactor device in said second direction; and

    an internal microprocessor system for accepting control signal inputs from said simulated rotary actuator and said keyboard, for presenting simulated directory index cards in the style of bottom-attachable rotary-type cards on said LCD screen, and for storing and retrieving information in and from an internal memory unit; and

    a power-storage system connected to, and for powering, said LCD screen, said simulated rotary actuator, said keyboard and said microprocessor.
