PROBLEM TO BE SOLVED: To provide a laser type angle detection device which detects an angle formed with an object on a remote point easily in a noncontact way by using a laser beam.;SOLUTION: This detection device is equipped with a laser oscillation means 17 for oscillating the laser beam which is a parallel beam, and a laser beam receiving means 18 for receiving the laser beam from the laser oscillation means 17. The laser beam receiving means 18 is equipped with an optical path 46 of the laser beam provided inside, a pinhole 48 provided on one end side of the optical path 46, and a light receiving element 49 provided on the other end side of the optical path 46, for receiving the laser beam from the pinhole 48 and converting it into an electric signal.;COPYRIGHT: (C)2004,JPO
