<p><P>PROBLEM TO BE SOLVED: To surely record that the instantaneous interruption of an input power source has occurred from the outside. <P>SOLUTION: This power source instantaneous interruption storage device includes: a detection means 2 for, when the voltage level of an input terminal 1 to which an external power is supplied is less than a predetermined threshold Vx, creating a detection signal which continues in a period when the voltage level is less than the threshold Vx; a decision means 3 for receiving the detection signal, and for, when the duration of the detection signal is less than a prescribed period t, creating an instantaneous interruption information; a storage means 5 for storing the instantaneous interruption information; and a control means 4 for creating verification information for verifying the instantaneous interruption information, and for successively repeatedly storing the instantaneous interruption information and the verification information in the different storage areas of the storage means 5. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
