Abstract:
To provide a galvanometer scanner that increases reliability by reducing burden on a mechanism unit. A galvanometer scanner converts a command for machining position on a machining target to movement commands for a rotary motor, a rotary motor, and a direct drive mechanism. If the movement command for the direct drive mechanism contains a weak direct drive component depending on the movement command for the rotary motor, and falling within an amplitude range not exceeding a predetermined amplitude and within a frequency range not falling below a predetermined frequency, the galvanometer scanner removes the weak direct drive component from the movement command for the direct drive mechanism, and then outputs control signals corresponding to the movement commands for the rotary motors and the direct drive mechanism. The galvanometer scanner controls the rotary motors and the direct drive mechanism based on the control signals.

Claim (Index 1):
A galvanometer scanner comprising a mirror for reflecting a laser beam emitted from a laser source, a rotary motor for rotating the mirror, a lens movable in a direction of the optical axis of the laser beam emitted from the laser source, and a direct drive mechanism for driving the lens, the galvanometer scanner scanning a machining target with the laser beam by reflecting the laser beam from the laser source on the mirror and passing the laser beam through the lens, the galvanometer scanner comprising:\n a conversion unit that converts a command for machining position on the machining target to movement commands for the rotary motor and the direct drive mechanism; a control filter unit that removes a weak direct drive component from the movement command for the direct drive mechanism, and then outputs control signals corresponding to the movement commands for the rotary motor and the direct drive mechanism if the movement command for the direct drive mechanism contains the weak direct drive component depending on the movement command for the rotary motor, and falling within an amplitude range not exceeding a predetermined amplitude and within a frequency range not falling below a predetermined frequency; and a control unit that controls the rotary motor and the direct drive mechanism based on the control signals output from the control filter unit.
