PROBLEM TO BE SOLVED: To perform the marking with excellent accuracy by stably and faithfully transmitting the scanning control signal from a control unit to a scanning unit. SOLUTION: A YAG laser marker device is provided with a control unit 10, a laser beam oscillation unit 12, and a scanning unit 40, the laser oscillation unit 12 is connected to the scanning unit 40 through a first optical fiber cable 60, and the control unit 10 is connected to the scanning unit 40 through a second optical fiber cable 62. The scanning control signal from a scanning control circuit on a control circuit board in an intermediate chamber of the control unit 10 is transmitted to the scanning unit 40 through the second optical fiber cable 62 in the mode of the optical pulse signal in a synchronous manner with transmission of the laser beam for marking from a YAG laser beam oscillator in the Baser beam oscillation unit 12 to the scanning unit 40 through the first optical fiber cable 60. |
