Field of the Invention The present invention relates to a projector device such as a liquid crystal projector, and more particularly to a projector device having an improved adjusting mechanism for a plate member such as a mirror that reflects light emitted from a lamp.

Description of the Related Art Since there is an increasing demand for displaying an image on a large screen, projector apparatuses for projecting an image on the screen are gradually becoming popular. FIG. 7 is a diagram showing a general configuration of a projector device. Here, the configuration of the liquid crystal projector will be shown and its operation will be described.

して液晶パネル１２に入射される。In FIG. 7, light emitted from a lamp 1 is condensed by condenser lenses 2 and 3 and is incident on a cold mirror 4. The light reflected by the cold mirror 4 is incident on the color separation mirror 5. Of the light incident on the color separation mirror 5, red (R) light passes through the color separation mirror 5 and is incident on the mirror 6. This R light is reflected by the mirror 6 and enters the liquid crystal panel 12.

Of the light entering the color separation mirror 7, G light is reflected by the color separation mirror 7 and enters the liquid crystal panel 13. Of the light incident on the color separation mirror 7, the B light is passed through the relay lens 8, the mirror 9, the relay lens 10, and the mirror 11 to adjust the optical path length of the R light and the G light to the liquid crystal panel 14. Is incident on.

される。As is well known, the liquid crystal panels 12 to 14 are supplied with R, G, and R to which a voltage corresponding to an image is applied.
Each of the B lights is modulated. The lights of the respective colors output from the liquid crystal panels 12 to 14 are combined by the combining prism 15 and projected on the screen 17 by the projection lens 16. In this way, the image is displayed on the screen 17.

囲をできる限り小さくする必要がある。By the way, in the projector device of this type, even if the dimensional accuracy of the optical components varies to some extent, or if the optical components are slightly displaced, the image displayed on the screen 17 is not displayed. The light from the lamp 1 is radiated in a range that is about 10% larger than the effective range of the liquid crystal panels 12 to 14 so as not to chip. On the other hand, in order to increase the brightness of the lamp 1, it is necessary to reduce the light irradiation range of the lamp 1 as much as possible.

置を調整するのが一般的である。When the irradiation range of the light from the lamp 1 is reduced, for example, the optical parts are precisely processed or the optical parts are attached to a highly rigid optical base so as not to cause image defects. Therefore, the dimensional accuracy and mounting accuracy of the optical component must be increased. Then, the cost increases and it is not possible to provide an inexpensive projector device. Therefore, it is general to provide an angle adjusting mechanism on a mirror such as the cold mirror 4 and adjust the irradiation position of the light from the lamp 1.

The present invention is not limited to such mirrors, and can be applied to all adjustment mechanisms for adjusting the position and angle of a plate-shaped member arranged in the optical path of light emitted to display an image on a screen. . Although the frame-shaped member 31 having the opening 31a is used in this embodiment, the opening 31a is provided for the mirror that does not need to transmit light, that is, the cold mirror 4 and the mirrors 6, 9 and 11 in FIG.

However, since the cold mirror 4 reflects visible light and transmits infrared rays, the frame member 31 having the opening 31a is provided in order to improve heat dissipation and prevent the cold mirror 4 from being affected by heat. It is more preferable to use.
