PURPOSE: A delay time control device using a D flip flop is provided, which improves delay of an input signal using the flip flop. CONSTITUTION: The first D flip flop(10) detects a signal being output by being varied according to switch operation of a user, and has a fixed output value using the detection signal as a clock signal. A filter circuit(20) detects a signal being output by being varied according to the switch operation of the user, and removes a noise signal included in the detection signal and then outputs it. An inverter(30) inverts a signal being output by being filtered in the filter circuit. And the second D flip flop(40) uses the signal inverted by the inverter as a clock signal, and applies a signal being output by the clock signal as a reset signal of the first D flip flop.
