直角四辺形である。The outer and inner surfaces of the front part 2, the rear part 4, the top part 6, and the bottom part 8 are provided parallel to each other or at right angles, respectively, and the cross section across the hollow hole of the target device 1 is a right quadrilateral.

For example, glossy satin finish treatment, silver coating treatment, plating treatment, etc. are performed to efficiently reflect laser light and prevent deterioration.

同一垂直面に含まれる直線を設定するものである。For example, as shown in FIG. 2, the target device 1 configured in this manner is placed at the junction between the wall 20 and the floor 22, and scans the laser beam in a vertical plane to scan the reference plane with the laser beam. The desired laser beam scanning device is used as a laser beam aiming target for the S1 wall. This is to set straight lines included in the same predetermined vertical plane on the floor and ceiling.

It is observed that it disappears at 10. In this way, whether or not the laser beam emitted from the laser beam scanning device 24 is directed in a predetermined direction in the horizontal plane can be easily and accurately determined by the presence or absence of the relatively bright laser beam spot on the target device l. be able to.
