Abstract
An object of the present invention is to provide a battery-driven ultrasound diagnostic apparatus in which the power consumption required for lighting keys little affects an operation time. An ultrasound diagnostic apparatus with lit operation keys comprises a power supply unit that switches power to be supplied to the components of the apparatus between power fed from a battery and power fed from the mains, and a lighting adjustor that ceases or minimizes lighting of operation keys when a detected ambient brightness level exceeds a predetermined threshold.
