Electronic memoranda device for storing, retrieving, and displaying a schedule of data in records

An electronic memoranda device for storing and displaying a schedule of data in records, each of said records including a time data field and an associated event data field, comprising:

• memory means for storing said records, said memory means comprising a plurality of memory addresses;
• display means for selectively displaying data read from the memory means;
• inquiry means for generating a time related inquiry signal, said inquiry signal comprising time data;
• first coincidence circuit means coupled to the memory means and inquiry means for comparing a part of the time data field in one record with a part of the inquiry signal, said first coincidence circuit means generating a first output when coincidence is found between the part of the time data field and the part of the inquiry signal;
• second coincidence circuit means coupled to the memory means, display means, inquiry means and first coincidence circuit means for comparing the entire time data field in one record with the entire inquiry signal when the first output is received from the first coincidence circuit means, and second coincidence circuit means causing the display means to display said one record when coincidence is found between the time data and the inquiry signal;
• field and
• control means for repetitively selecting said time data fields from the memory means for comparison by said first coincidence circuit means upon receipt of said inquiry signal.
