FIELD: physics, measurement.
SUBSTANCE: device includes sampling needle for sample taking and driving device for translation movement of the needle. Sampling needle is mounted on swinging arm tilted against sampling needle and rotating around its own axis. Driving device for sampling needle includes slides and chain spanned in radial direction between guiding and idle pulleys. One of the pulleys serves as joint on swinging arm. Slides can perform translation movement against swinging arm.
EFFECT: simplified sampler construction.
