摘要： A surveying instrument having an AF apparatus, provided with a focusing lens and a collimation telescope, includes a focus detector for detecting a focus state through the collimation telescope, and a controller for moving the focusing lens of the collimation telescope to a focal position, based on the focus state detected by the focus detector. The surveying instrument includes a single focus mode at which only one detection of the output of the focus detector and only one control operation of the controller based on the detected output are carried out, and a continuous focus mode at which a plurality of detections of the output of the focus detector and a plurality of control operations of the controller based on the detected outputs are sequentially carried out, the single focus mode and the continuous mode being selectively performed.

摘要： A surveying instrument includes a sighting telescope optical system, a distance measuring system which outputs first data, a phase detection autofocus system which and outputs second data, and an AF driver which moves a focusing lens of the sighting telescope optical system to bring the sighting object into focus in accordance with one of the first data and the second data. A surveying instrument is also disclosed, which includes a sighting telescope and an AF drive unit which is provided separately from the sighting telescope, wherein the AF drive unit can be mounted to and dismounted from a body of the surveying instrument.
