<p>PROBLEM TO BE SOLVED: To easily specify a position without necessitating a measuring means by preparing plural light emitting bodies in which at least two optical axes turned on with a power source are provided so as to cross and indicating a position at a crossing point of the optical axes. SOLUTION: Two LED pointers 43 are electrically energized, and a position of a laser oscillator 3 is adjusted together with a scanning part 4 so that a work is positioned in a place where irradiating lights are crossed. In a laser controller 2, an input result by an input indicator 1 is stored in a memory of a microcomputer 21, printing signals based on a stored frequency and a duty factor are imparted to the laser oscillator 3 and scanning signals are imparted to the scanning part 4 based on a pattern stored in the memory. In the scanning part 4, a total reflection mirror which is provided in the output shaft of a galvano motor provided in a scanner 41 is moved by the scanning signals of the microcomputer 21, and laser beams are deflected and scanned. The work W is irradiated by the laser beams via a fθlens 42 and marked.</p> |
