    摘要: A projector has an image generating device for generating an image, and a housing, having the image generating device disposed therein and having an opening defined therein for emitting therethrough projection light representing the image from the image generating device. A projection mirror is mounted on an outer surface of the housing for reflecting the projection light to project the image onto a projection surface. An optical system is disposed in the opening for applying the projection light to the projection mirror. The projector also has a foreign matter detector for detecting foreign matter which enters a light path of the projection light between the optical system and the projection mirror.

    摘要: A reflecting mirror 4d has a rotation axis 7 which is inserted into a bearing 8 of a case 1. Accordingly, the reflecting mirror 4d is capable of rotating with respect to the case 1 and only the reflecting mirror 4d is capable of adjusting the set up angle α made with the case 1. When the set up angle is changed, the reflecting angle of the projected ray on the reflecting mirror 4d is also changed. Therefore, the launching angle of the projected ray 5 with respect to the case 1 can be adjusted.
