Abstract
A fixture plate is fixed by a screw onto an optical housing of the optical head device at a portion corresponding to where a monitor signal path portion and an act signal path portion are arranged overlapping one another. The two signal path portions are portions of two types of signal paths discretely formed on a flexible wiring board. The fixture plate is composed of a conductive material. One of the monitor signal path portion and the act signal path portion is covered by the fixture plate and fixed by a screw onto the optical housing together with the fixture plate, while the other of the monitor signal path portion and the act signal path portion is hooked in place by a hook provided on the fixture plate. The fixture plate is interposed between the monitor signal path portion and the act signal path portion.
