A laser measuring instrument comprises a light emitter, a driver, a scanning unit, a light receiving signal processing module for detecting a reciprocating time per pulsed light of a distance measuring light and performing a distance measurement, and a timing generating circuit for issuing a timing signal, wherein the timing generating circuit is configured to issue a timing signal for making the light emitter pulse-emit in a short cycle and a timing signal for pausing a light emission, the driver is configured to make the light emitter pulse-emit according to the timing signals, a light emission time interval in the short cycle is set such that a measuring point is multiply irradiated with the pulsed light by two or more times within a time when the pulsed light passes the measuring point, and the light receiving signal processing module is configured to integrate acquired light receiving signals and to carry out the distance measurement.
