Abstract

PURPOSE:To conveniently utilize a view finder at the time of taking and reproducing videos, by providing a liquid crystal displaying body and fluorescent tube and adding a rotating function which rotates around the fluorescent tube. CONSTITUTION:Part of rays of light of a fluorescent tube 1 is directly projected on a diffusing plate 3 and the other part reaches the plate 3 after it is reflected by a reflecting plate 2. The rays of light unified by the diffusing plate 3 display a video by means of a liquid crystal body 4 under optical control in accordance with video information and the video is enlarged by a lens 5. Fitting sections 7 of this view finder to a camera are provided on a case 6 at both ends of the fluorescent tube 1 and, because of the fitting sections 7, the view finder can be rotated around the fluorescent tube 1 against the camera. Since such a rotating function that the fixed part of the fluorescent tube 1 can be rotated around the axial direction of the tube 1 is given to this view finder, the view finder can be utilized conveniently when the camera is used for taking and reproducing videos.

As stated above, according to the present invention, both end portions (electrode areas and low brightness areas) of the fluorescent tube used as a backlight of a liquid crystal display, which do not contribute as a light source, are placed in the case of the vinyl finder. However, by using the protruding part of the fluorescent tube to fix the EVIF to the camera, the overall size of the KVI can be greatly reduced. This makes it possible to reduce the size of the camera as a whole, while also increasing the degree of freedom in design. Furthermore, the fixed part of the fluorescent tube part can be rotated around the axial direction of the fluorescent tube to give the EVF a rotation function, allowing the camera to take pictures.
