Therefore, the point designating direction of the marking point designating member can be moved and positioned horizontally so that the marking point is designated. Therefore,
In the same way as before, the surveying operator's hand was used to attach the surveying pole 19.
By positioning just above the marking point,
The marking point can be designated with much higher accuracy than when the marking point is designated. Therefore, marking can be performed with high accuracy by marking the marking point designated by the point designated direction. In the present invention, the marking point indicating member is a laser oscillating means such as a laser pointer 20 capable of oscillating and emitting a laser beam such as a laser beam 20a.
