Abstract
This invention provides a laser beam transmitting apparatus which can make the levelling work unnecessary to thereby mitigate the burden of an operator and improve work efficiency. The apparatus is provided with a base, a beam transmitter for supplying a beam of light, a housing, for holding the beam transmitter, and a levelling mechanism provided between the housing and the base, the housing being oscillatably supported on the base, and the center of oscillatory movement thereof lying above the centroid of the housing. Thus, there is achieved double bearing combined with a precise levelling mechanism, provided between the beam transmitter and the housing.
