PURPOSE: A common circuit is provided to prevent noises generated during oscillation of a magnetron by outputting key scan pulses only in the non-oscillation section of the magnetron. CONSTITUTION: A microwave oven comprises a magnetron for generating microwave as a main heating source; a display; a touch sensor panel connected to a certain part of display exclusive output ports; and a micro computer for outputting key scan pulses of the touch sensor panel only in the non-oscillation section of the magnetron. The micro computer outputs one or more key scan pulses in the non-oscillation section of the magnetron.
