AUTOMATIC COUNTER OF STATED INTERVAL OF LENGTH WITH THE AID OF NONIUS Russian patent published in 2005 - IPC

FIELD: the invention refers to measuring technique particularly to devices for linear measurements and may be used in machine-tool construction.

SUBSTANCE: the arrangement has a bed, a movable mechanism of a mobile carriage, a main and a nonius scale of a measuring ruler, optical units of a main and a nonius scale of a measuring ruler, a unit of photo , elements, units of coincidence of the stated number of the mark of the main and the nonius scale and exact linear meaning of the stated number of the mark of the main and the nonius scale, a stop unit of the mobile carriage, a unit of algebraical summation, a correction memory unit. At that the main and the nonius scales of the measuring ruler are reduced relatively to the minimum interval of length of 0,5 mm with the aid of photographing in 10 and 40 times.

EFFECT: the invention provides increased accuracy at measuring linear distance.
