Abstract

Abstract A telephone card index, having a switch connected to the card finder for initially locking on to a memory section of a miniprocessor.[., a.]..Iadd.. .Iadd.A .Iaddend.key aligned with each name line of the card locates the exact memory address of the number to be called with pre-recorded dial signals at the memory address for an individual name line, .[.permits.]. .Iadd.permitting .Iaddend.automatic telephone dialing of the selected number. A keyboard in the circuit, with a display.Iadd., .Iaddend.permits adding, changing or recalling the recorded number at each address.

Claim 1
Independent Claim 817 words
Telephone index and combined switch arrangement for memory stored dialing data for automatic dialing telephones comprising: (a) a housing having an entry keyboard switch means thereon for entering numbers to be stored and display means for displaying the number entered by said entry keyboard.[.,.]..Iadd.; .Iaddend. (b) multiple card index means for a visual listing of names and telephone numbers, each card including individual lines for individual numbers arranged in the same position on the cards, wherein said card and lines are divided into a plurality of left-hand lines and a plurality of right-hand lines, said left-hand and right-hand lines being substantially equal in number, and further including a cover positioned over said cards and finding means on said cover for positioning an individual card for visual display of the card's content; (c) card switch means including an individual .[.contract.]. .Iadd.contact .Iaddend.associated with each card index and activated by positioning said finding means to display the particular card to thereby close said card switch means completing a circuit for said card including a common lead and a common bus bar associated with said finding means and an individual lead for each card, said card switch means being initially energized when said cover is closed; (d) selector switch means including a left-hand and a right-hand series of push buttons with one button in said left-hand series for and adjacent to each of said left-hand lines and one button in said right-hand series for and adjacent to each of said right-hand lines so that said selector switch means is activated by a push button to close a circuit for a particular line positioned on an individual card to thereby complete a first circuit associated with the card contained data and close a second circuit associated with a particular line on a card to retrieve and automatically dial a telephone number stored at a location in the memory associated with said particular line; and (e) a visual display panel means on said housing adjacent said cover for displaying the number dialed by actuating said card switch and selector switch. .Iadd. 2. In a telephone index and combined switch device for memory stored dialing data for automatic telephone dialing, the combination comprising: multiple card index means including a plurality of cards one on another for visual listing of names and telephone numbers, each card including individual lines for individual names and telephone numbers, a cover positioned over said cards, and finding means on said cover for positioning an individual card for visual display of the card's content; card switch means activated by positioning said finding means, said card switch means initially latching onto a memory block of data representing an individual card when said cover is closed, said latching being completed via said card switch means when the cover is closed whereby, with a first card selection and with said cover closed, the latching for the first card selected remains in effect until said finding means is moved to a second card selection and said cover is closed; and selector switch means including a number of pushbuttons equal to the number of lines on one of said cards, one of said pushbuttons associated with each of said lines, each said pushbutton connected in a second circuit corresponding to a particular line and a particular selected card which, upon activation of a selected pushbutton, is effective to retrieve and automatically dial a telephone number stored at a location in a memory corresponding with the telephone number of the particular line that has been selected. .Iaddend..Iadd. 3. In a telephone index and combined switch device as set forth in claim 2 wherein said card switch means has a a circuit-completing portion carried by said cover. .Iaddend..Iadd. 4. In a telephone index and combined switch device as set forth in claim 2 wherein said card switch means includes a common bus bar, a contact for each card, and a circuit-completing portion that is movable conjointly with said finding means for electrically connecting said common bus bar to successive contacts for an individual selected card according to the position of said finding means. .Iaddend. .Iadd. 5. In a telephone index and combined switch device as set forth in claim 2 including a housing having an entry keyboard switch means thereon for entering numbers to be stored and display means for displaying the number entered by said entry keyboard. .Iaddend..Iadd. 6. In a telephone index and combined swich device as set forth in claim 2 wherein each of said cards and lines are divided into a plurality of left-hand lines and a plurality of right-hand lines, said right-hand lines being substantially equal in number. .Iaddend..Iadd. 7. In a telephone index and combined switch device as set forth in claim 2 including visual display panel means on said housing adjacent said cover for displaying the number dialed by actuating said card switch means and selector switch means. .Iaddend.
