る。In other words, during marking work in surveying, the device of the present invention installs a laser beam irradiation device in front of the wall surface that requires marking, and irradiates a laser beam in two-dimensional directions vertically and horizontally with a laser beam irradiation gun via an encoder-equipped motor. The marking operator holds a wireless transmitter at a position close to the wall surface to be surveyed, and the signal from the wireless transmitter is input via the receiver as an operator signal to the microcomputer. Then, the microcomputer outputs rotation angles corresponding to the light projecting points of the marking wall surface stored in the microcomputer to the vertical rotation motor with an encoder and the horizontal rotation motor with an encoder, respectively. That is, as shown in FIG. 3, if the distance between the wall surface (a) and the laser beam irradiation gun (1) is L, then from the base point P to L
The marking points P° that are l apart are obtained by rotating the laser beam irradiation gun (1) by a displacement angle f) = jan-1", and the displacement angle (θ) is obtained by rotating the motor with an encoder on the vertical or horizontal side. In this case, the worker waits at a position near the projected laser beam spot, and by marking the spot position, the worker can continue marking the wall surface one by one.
