  "textContent": "A surveying instrument capable of irradiating a spotlight as visible light for centering toward a position below a vertical axis of a surveying instrument main body is configured such that that an irradiation shape of the spotlight is a toric shape. When visible light for centering which passes through a center point of the surveying instrument and is projected on a position right below the surveying instrument is projected in a toric shape having a hole opened at a center like a donut shape, both of an inner circle and an outer circle can be recognized, so that many guides are provided, and it is easier for a worker to align the toric shape with the target point than a point shape, so that the burden of a centering work on the worker is reduced.",
