Description

technical field

[0001] The invention relates to a working position measuring device which rotates and irradiates a laser beam and measures the working position according to the receiving state of the laser beam. Background technique

[0002] In the prior art, a typical device for rotating and emitting a laser beam to form a reference plane includes a rotating laser device and a laser receiving device for receiving the laser beam.

[0003] The rotating laser device is a device that rotates and irradiates a laser beam in a point shape so that the beam forms a reference plane. For example, the laser beam is rotated and irradiated in the horizontal plane to form a horizontal reference plane; the laser beam is rotated and irradiated in a vertical plane to form a vertical reference plane; the laser beam is rotated and irradiated in an inclined plane to form an inclined reference plane.

[0004] The laser receiving device is a device that has a light receiving unit that receives a...
