Abstract
An ID card-controlled system drive having reduced power consumption includes an ID card in which a fixed user ID is stored, an ID card reader for outputting an appropriate signal by reading data stored in the ID card, a power supply control section for outputting an operation signal to permit a user to use the system drive after comparing the data from the ID card with the stored data and determining that the data corresponds, an auxiliary power-supply for providing power to operate the ID card reader and the power supply control section, and a main power supply for supplying the driving power source to operate system, which is variable according to the driving signals output from the power supply control section. Using this ID card-controlled system can reduce power consumption for reading the ID card, keep important information secret, and supply main power to the system only when the ID card coincides with a registered user ID.
