ABSTRACT:
An automatic telephone dialing apparatus wherein a plurality of telephone numbers are stored in a storage medium for rapid retrieval thereof upon the actuation of a single button to produce a complete dialing signal for a telephone system. The apparatus is designed so that information identifying successive numeral digits of each telephone number is stored in accordance with various alternative schemes such that numeral digits in corresponding digit positions of each telephone number form at least one of a plurality of separate groups each group being stored at a different region of the storage medium. Thus, in one example thereof, the digits corresponding to the first numeral of each telephone number are stored successively at a first region, the digits corresponding to the second numeral of each telephone number are stored successively at a second region, and so on, until the digits corresponding to the last numeral of each telephone number are stored at a last region of the storage medium all in the same order.
