Abstract
A line-like (line) laser beam flux irradiating apparatus includes a laser source which emits a divergent laser beam flux, a conversion lens which converts the divergent laser beam flux to a parallel laser beam flux, a first lens which forms a first line-like laser beam flux, a second lens which forms a second line-like laser beam flux intersecting the first line-like laser beam flux, and a reflective optical system having a first reflective surface which reflects the parallel laser beam flux toward the first lens and a second reflective surface which reflects the parallel laser beam flux toward the second lens. The parallel laser beam flux is simultaneously guided to the first and second reflective surfaces so as to form a cross-wise line-like laser beam flux on the same plane by the cooperation of the first line-like laser beam flux and the second line-like laser beam flux.
