PROBLEM TO BE SOLVED: To provide an optical scanner device capable of suppressing destruction due to impact such as dropping.SOLUTION: An optical scanner device 1 comprises: a laser light source 3 for oscillating a laser beam L; a lens 4 for shaping the laser beam L into a parallel beam La; an optical deflector 10 for deflecting and scanning the beams La in a prescribed direction; a laser driver 2 for driving the laser light source 3; a control circuit 5 for outputting to the optical deflector 10 a driving signal Dh for driving the optical deflector 10; an arithmetic processing circuit 7 for controlling the laser driver 2 and the control circuit 5; and an acceleration sensor 6 for outputting an acceleration detection signal Ac to the arithmetic processing circuit 7. The arithmetic processing circuit 7 controls the control circuit 5 to stop deflecting and scanning the beams La by the optical deflector 10 if a level of the acceleration detection signal Ac inputted from the acceleration sensor 6 is equal to or greater than a predetermined threshold. |
