Electronic memoranda device for storing, retrieving, and displaying a

Abstract

An electronic memoranda device especially suitable for the retrieval of stored data with low energy consumption is provided. In the electronic memoranda device, days, times, and schedules, and the like, are stored in a data memory. At regular intervals a key portion of these stored times is compared with a key portion of a current time signal outputted from a timekeeping circuit. When the key portion of time data read out from the data memory coincides with the corresponding portion of the currently outputted timekeeping signal, the entire data stored in memory is scanned for coincidence with the complete timekeeping signal. Coincident data is outputted for display. When the initial survey of the memory indicates that no data is stored corresponding to the key current time unit provided by the timekeeping circuit, the inspection operation of the memory is interrupted until the occurrence of the next time unit wherein inspection of the memory is repeated.
