Embodiment Construction

[0047] Hereinafter, an embodiment of the present invention will be described based on the drawings.

[0048] [1. Appearance of the projector]

[0049] figure 1 and figure 2 A projector 1 including an optical device according to the present invention is shown in, figure 1 is a perspective view from the upper front side, figure 2 It is a perspective view seen from the lower back side.

[0050] The projector 1 modulates a light beam emitted from a light source according to image information, and amplifies the optics projected on a projection surface such as a screen. The projector 1 has an outer casing 2 that accommodates a device main body including an optical device described later, and an outer casing 2 . Projection lens 3 exposed from housing 2 . The projector 1 is placed in a large store or in a public event place, and displays a projected image on a large screen to provide image information to a large number of viewers.

[0051] The projection lens 3 functions as a ...

Abstract

The invention provides an optical device and a projector capable of reducing the number of parts and manufacturing cost and realizing easy setting and posture adjustment of a reflector. The optical device has a convex camber (404A) arranged on the backside of a reflecting surface arranged inside a reflector (424) and bulging towards the outside of the reflector (424) as well as a pair of fixing parts (404C) respectively arranged on the backside of the reflecting surface arranged inside a reflector (424), wherein the convex camber (404A) is in the shape of a convex curved surface and contacts a side wall (410G) when the reflector (424) is arranged along a side wall (401G); the fixing parts (404C), which clamp the convex camber (404A), are respectively arranged and bulge towards the outside of the reflector (424); moreover, the side wall (401G) is formed into a pair of fixing slot parts (401J) which extend out in the containing direction R of the reflector (424) and guide the fixing parts (404C) to move; moreover, the fixing slot parts (401J) can realize the clearance fit of the fixing parts (404C).

Description

technical field [0001] The present invention relates to optical devices and projectors. Background technique [0002] Conventionally, there has been an optical component including a plurality of optical components arranged on the optical path of a light beam emitted from a light source, an optical component housing for setting the illumination optical axis of the light beam inside, and accommodating the plurality of optical components and arranged at a predetermined position. The projector of the installation is used. [0003] Here, as the optical components, a plurality of optical elements for changing the optical characteristics of the light beam emitted from the light source, and a plurality of optical elements for reflecting and / or transmitting the light beam emitted from the light source and guiding the light beam to a predetermined illumination optical axis are used. multiple mirrors, etc. [0004] In such a projector, in order to obtain a clearer projected image, it...
