Abstract

PURPOSE: To obtain a timer that can prevent information on an electronic equipment with an incorporated volatile memory from being erased, by connecting an input-side electric power source through a timer switch and derectly.
CONSTITUTION: Through switch SW that turns on a fixed time time later through clocking method 2, output terminal OUT1 of timer 1 is connected to an input-side electric power source so as to actuate an electronic equpment with an incorporated volatile memory at a desired time. Output terminal OUT2 of timer 1, on the other hand, is connected direct to the input-side electric power source at any time and the volatile memory is supplied invariably with electric power without reference to the timer time, so that memory contents of the memory will never disapper. Therefore, the timer which can prevent information on the electronic equpment with the incorporated volatile memory from being erased can be obtained.
