Title:
PROJECTOR DEVICE
Document Type and Number:
Japanese Patent JP3838983
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a projector device consisting of components capable of dealing with an environmental temperature change.
SOLUTION: The projector device has a light source device, an image forming element and an imaging optical system, in which the imaging optical system is comprised of a plate fixed to a casing and a reflecting mirror attached to the plate by means of a holding member. The device is provided with a bushing 10 acting as a sliding mechanism between the plate 6 for fixing the holding member mounted with the reflecting mirror and the casing 9 for fixing the plate 6 so that the positional change of the reflecting mirror is eliminated by allowing temperature deformation to release.
