Abstract

PURPOSE:To measure an angle formed by two planes easily with high precision by applying light beams to two surfaces to be measured and by detecting relative positional relations of detector at which reflected lights are obtained. CONSTITUTION:Laser beams emitted from a laser transmitter-reciever 5 and reflected by a matter M to be measured are received and detected by the laser transmitter-receiver 5. A reflected beam detecting device 7 detects from detection signals that the reflected beams in the prescribed directions are received correctly and gives signals to a position measuring device 8. The position measuring device 8 measures the detection angle of a rotary angle detector 3 at the time when it receives signals from the reflected beam detecting device 7 and sends the data of angle values to an operation device 9. The operation device 9 calculates the angle formed by the two planes of the matter M and indicates the same in an indication device 10.
