Abstract:
It is desirable for light regulation devices to be configured so as to be small, to involve easy steps of assembly in a assembly task, and to allow a stable oscillating operation to be realized. This light regulation device has a start-up mechanism and an electromagnetic drive source. The start-up mechanism is configured from a rotating shaft that accommodates a magnet and has two flanges on the side peripheral surface, and a substrate on which the rotating shaft is axially mounted in a rotatable manner. The rotating shaft is fitted into a hole or notch formed in the substrate, an upper substrate is disposed so as to be sandwiched between the flanges, and the electromagnetic drive source is provided upright on the substrate with a desired tilt.
