Abstract
In sample transporting devices, the operation sound of a belt conveyor and the driving sound of a drive motor are caused by operating a transporting line when transporting samples, and reducing the driving sound and operation sound is required. In the present invention, a detection signal of the detection sensoris detected by a detection unit, and a control unitperforms controlling to change the current value and the driving frequency of a belt driving motorof a transporting lineand change the driving torque and the driving rotary speed of the transporting line on the basis of the amount and number of samples transported by a belt, wherein the amount and number of samples transported by the belt can be obtained by the detection signal or a sample amount measured by a sample transporting system. Accordingly, noise reduction is achieved by driving the belt driving motor under suitable conditions according to the amount and number of the samples transported by the transporting line, and reducing the operation sound of the belt driving motor or mechanisms and the like.
