Abstract:
A projector is provided with a radiation source adapted to radiate an electromagnetic wave during an operation and an exterior housing adapted to house the radiation source inside, wherein the exterior housing includes a first housing made of synthetic resin, and a second housing including a shield material adapted to block the electromagnetic wave, and disposed at a position for covering the radiation source in a plan view.
Abstract:
A projector includes a light source device and an exterior casing, wherein an engagement moving portion slant surface is formed at an engagement moving portion, the engagement moving portion slant surface abutting on an engaging protrusion in a sliding manner when the engagement moving portion is moved to a not-engaging position to press the engaging protrusion toward a top portion.
Abstract:
