Abstract: A control device controls a scanning unit and a drive unit to scan laser light. In addition, the control device controls a focal point adjustment unit and a drive unit to adjust the focal position of the laser light. In a display mode in which a processing subject is irradiated with visible light, the control device controls the scanning unit and the drive unit to scan the visible light. The control device does not change an inter-lens distance of lenses of the focal point adjustment unit.

Abstract: A focal length adjusting device is provided with: a retention unit for retaining a first lens; a guide unit for supporting the retention unit so as to allow movement along an optical axis of laser light; a stepper motor that has a shaft body and is arranged so that the central axis of the shaft body is orthogonal to the optical axis; and a conversion unit that is interposed between the shaft body and the retention unit and converts rotational movement of the shaft body into linear movement of the retention unit. The conversion unit comprises, between itself and the retention unit, a coupling unit that transmits kinetic force from the conversion unit to the retention unit in a direction parallel to the optical axis but does not transmit same in a direction parallel to the central axis of the shaft body.
