FIELD: machine building.
SUBSTANCE: device consists of appliance (10 or 40, or 50) of optical check with at least one source (14 or 52) of light designed for direction of light power to container as container is rotating around its axis, and of at least one sensor (24 or 58) designed for reception of light power from source of light upon contact with container. Processor (26 or 48, or 60) of information is connected to the sensor for detection of container rotation as function of sensor output signal fluctuation. Rotation of container causes some fluctuation occurring at the output of the sensor as a result of light power interaction with the container. Absence of any detected fluctuations at the output of the sensor indicates that the container does not rotate.
EFFECT: simplified check of container during its rotation.
