Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a display device having a display section such as a receiving section or a viewfinder of a video camera.

(Prior art) As television receivers and video cameras are becoming more compact, the display parts of television receivers and video camera viewfinders are also using liquid crystals and small cathode ray tubes. A smaller version is now in production. However, the conventional display section 1 is not compatible with the portable television 2 shown in FIG. 13 or the video camera 3 shown in FIG.
Each was integrated into the main body. For this reason, when viewing images on the portable television 2, it is necessary to hold the image at eye level with one's hand, which imposes restrictions on the person's movements while viewing. Conventionally, the viewfinder 4 of the video camera 2 has been fixed to the end of a viewfinder holder 5 that is slidably provided on the main body of the video camera 2, as shown in FIG. For example, when looking through the viewfinder 4 with the right eye, the viewfinder holder 5 is retracted as shown in FIG. 16, and when looking through the left eye, the viewfinder holder 5 is extended as shown in FIG. For this reason, there is a problem in that when looking through the left eye, the viewfinder holder 5 covers the right eye, making it impossible to check the surroundings with the naked eye while copying.

Furthermore, when the video camera 2 is lifted up to take a picture at a high angle, the user cannot see into the viewfinder 4 and therefore cannot confirm the recorded image.

Furthermore, when shooting from an angle where the lens is placed below the eye level when standing, the user is likely to bend over, which makes the shooting process more tiring, and the angle cannot be easily changed. If you are shooting in a place where your footing is unstable, the angle may be off because you have to look at your feet when you use the lens to take the picture.
There were other problems.

(Problems to be Solved by the Invention) As described above, the present invention solves the problem that it is impossible to watch television in a comfortable posture because the display unit is integrated with the television receiver or video camera. This solves problems such as difficulty in confirming the images taken due to the angle, etc., and allows you to watch TV while walking around the pond, or to take images that are constantly taken with a video camera from the same position. The purpose is to provide a display device.

[Structure of the Invention (Means for Solving Problems)] In order to achieve the above object, the present invention separates the display section from the television receiver main body or the video camera main body via wiring, and separates the display section from the eyepiece ( It was designed to make people look dumbfounded.

(Function) According to the above configuration, you can watch the TV screen while doing other activities without using your hands, and when shooting with a video camera, there are no restrictions on the position in which you hold the video camera body, and your eyes Photographs can be taken regardless of the position of the camera and the position of the camera body.
