TIME SETTING SYSTEM & METHOD USING PERSONAL COMPUTER

摘要

A device which inputs the present time and the reserved time to the device according to the key signal of the key matrix that informs the present time and reserved time, using personal computer that outputs selectively the present time and the reserved time data and address signal that controls input and output. The device consists of : a decoder which outputs the input signal by decoding the personal computer's address signal ; a latch circuit latches in other and outputs the present time and the reserved time data inputted from the personal computer according to the input signal of the decoder ; a driving circuit which approves selectively to the device key signals corresponding to the present time and the reserved time data that approved from the latch circuit connected to the keys of key matrix in parallel.
