Abstract

PURPOSE: To obtain a specified alarming of a day's programs etc. when a power source is turned on by providing a clocking device which is supplied with power source constantly, and detecting and holding the concidence of the clock date with the preset program execution date.
CONSTITUTION: An internal power source 151 is built in a clocking device 15 which forms an office computer together with a keyboard 12, a CPU11, a magnetic disc 14, a CRT13, etc., and power source is constantly held supplied thereto including the time when the external power source is held interrupted. Hence, the device 15 counts the date with a clocking circuit 152 at all times, performs the comparison with the storage content of a date memory 153 in a comparator 155, detects the coincidences and has the coincidence detection signal held in an FF154 etc. According to the external power source closing of every morning, the program of that date having been stored in a disc 14 is automatically displayed and announced in a CRT13 by the coincidence output of the FF154, and the need for cumbersome work of checking the execution program to be processed on that date at the turning of the external power source is eliminated.
