Abstract

An object of the present invention is to provide an automatic analyzer capable of generating ultrasonic waves from different piezoelectric elements without reducing the intensity of the ultrasonic waves. Therefore, the present invention provides an automatic analyzer including: a piezoelectric element configured to generate ultrasonic waves for stirring a sample and a reagent; an amplifier configured to drive the piezoelectric element; a relay switch provided between the piezoelectric element and the amplifier; and a control unit configured to control the amplifier and the relay switch. When a first piezoelectric element is driven, the control unit turns on a positive voltage-side switch and a GND-side switch in a first relay switch provided between the first piezoelectric element and the amplifier, and turns off a positive voltage-side switch and a GND-side switch in a second relay switch provided between a second piezoelectric element and the amplifier, and when the second piezoelectric element is driven, the control unit turns on the positive voltage-side switch and the GND-side switch in the second relay switch, and turns off the positive voltage-side switch and the GND-side switch in the first relay switch.
