<p>PURPOSE:To correctly write all information by forcedly turning ON an operating power source and displaying that data are under writing regardless of the operating state of a power supply switch until it is completed to write all the information. CONSTITUTION:When the inputted information are written into an Electrically Erasable PROM (EEPROM) 109, a CPU 106 closes the switch circuit of a relay 110c in a power supply part 110. Thus, even when a power supply switch S1 is turned OFF, the operating power source is forcedly turned ON, an LEDD is turned on and it is displayed that the data are under writing, until it is completed to write all the information. Accordingly, even when the power source is turned OFF while information are written into the EEPROM 109, all the inputted information can be correctly written and an operator can know that the data are under writing.</p> |
