Abstract

PURPOSE:To eliminate the variance in the laser light projection conditions onto a work by plurally branching the laser light projected from a piece of an optical fiber by plural mirrors and projecting on plural works simultaneously or at time difference. CONSTITUTION:The laser light 13 emitted from a laser oscillator 12 is condensed at its all energy by a condensing lens 14 and led to an optical fiber 15. The laser light 16 emitted from this optical fiber 15 spreads once but becomes of a parallel beam by the condensing lens 17 arranged at a focal point from the projection end of the optical fiber 15 and branched in three parts by a half mirror 18 and total reflection mirror 19. This branched laser light is condensed by a condensing lens 20 respectively and projected on the respective work 21. The laser light projecting angle 22 onto the work 21 is eliminated at its variance on each branch route by the effect of the condensing lens 17.
