Abstract

PURPOSE:To secure the sure writing time to a nonvolatile memory and also to decrease the writing frequency by performing the control so that a 2nd open/ close means connected in parallel to a 1st open/close means for a fixed period of time after the 1st one/close means is opened. CONSTITUTION:When an open/close switch 2 is turned off, a commercial power supply is applied via a contact of a relay 3. Thus the supply of power is never interrupted. A contact open/close detecting means 6-1 outputs a signal of a high or low level to a circuit route 6-3 and at the same time detects said signal out of a circuit route 6-4 to monitor the open/close state of the switch 2. When an open state of the switch 2 is detected, this detecting information is transmitted to a microcomputer 6 and the operating state set right before the switch 2 is turned off is written into a nonvolatile memory 7. When this write program is carried out, the information on the end of execution of said program is transmitted to a relay open/close means 6-2. Then the contact of relay 3 is turned off and the commercial power supply is not completely applied.
