Abstract

PURPOSE:To easily set a password while securing secret holding ability by sending the password specified on a cordless key unit, and receiving and registering the password by an information processor main body. CONSTITUTION:The key input of the cordless key unit is sent from a light emission unit 35 and received by the photodetection unit 21 on the information processor main body side. The main body once receiving the password and a protection item stores the password and corresponding protection item temporarily in a RAM 22 for the photodetection unit which is powered by a battery at all times. Then when the main power source of the main body is ON, the stored data are recorded in one of memory parts 15, 17, 19, and 20. When the main power source is OFF, on the other hand, the main body enters a stand-by state, but when the power source is turned ON, the data stored in the RAM 22 are recorded in the memory part by a CPU 10. Thus, the main body and key unit are separately stored to improve the maintenance, and the setting can be done without turning ON the main body power source.
