Abstract

Since dioptric systems (1, 2) move a second laser beam group collectively along a laminating direction relative to a first laser beam group and use aligning transmission/reflection optical systems (1R, 2R, 1S, 2S), a laser beam pattern consisting of the first and second laser beam groups output from the transmission/reflection optical systems (1R, 2R, 1S, 2S) is so shaped as to be longer in a laser bar laminating direction and separate optical systems are used for moving and aligning, whereby individual optical systems have simple configurations.
