Abstract

(57) [Summary] [Object] An object of the present invention is to allow a relative position variable member connecting a video camera body and a viewfinder to be housed inside the video camera body. [Structure] A relative position variable member 1 that connects a video camera body 4 and a viewfinder 3 and is composed of a plurality of hollow rod-shaped members, which are extendable and contractible. Pass the wire rod 7 inside,
By arranging the relative position variable members 1 and 2 in the empty space of the video camera body 4, the relative position variable members 1 and 2 can be housed inside the video camera body 4. [Effect] According to the present invention, a relative position variable member, which is not desirable in appearance, can be housed in the video camera body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a viewfinder used in a video camera, and more particularly in a shoulder type video camera.

[0002]

2. Description of the Related Art As a conventional technique, for example, SAIKAI Sho 62
There is an example of the structure of the viewfinder described in Japanese Patent No. 181072. According to the conventional example, the relative position variable member is attached to the outside of the video camera body, and this method tends to be subject to design restrictions. Particularly in recent years, the size of the video camera body has been reduced, and it is not preferable in terms of design that the relative position variable member is externally attached.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a viewfinder structure which is excellent in design and function even for a miniaturized video camera body. It is in.

[0004]

According to the present invention, a relative position variable member in a viewfinder is constructed so that a plurality of hollow rods can extend and contract, and the relative position variable member is an empty space inside a video camera body. It is achieved by arranging in.

[0005]

By connecting the viewfinder and the video camera with the relative position varying member described above, the wire rod is passed through the inside of the hollow rod, and the relative position of the viewfinder with respect to the video camera main body can be changed. The purpose is achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view showing an embodiment of a video camera using the viewfinder structure according to the present invention. In this figure, the viewfinder 3 is located closest to the video camera body 4, and the relative position variable members (hereinafter abbreviated as variable members) 1 and 2 are housed inside the video camera body 4. At this time, the first variable member 1 and the second variable member 2 connecting the video camera body 4 and the viewfinder 3 are inside the video camera body 4 and cannot be seen from the outside.

FIG. 2 is an external perspective view showing a state in which the viewfinder 3 is most pulled out from the state of FIG. At this time, the viewfinder 3 and the video camera body 4 are fixed by the variable members 1 and 2 housed inside the video camera body 4 in FIG.

FIGS. 3 and 4 are views showing the states of FIGS. 1 and 2 seen from the front side, respectively.

FIG. 5 is a perspective view centering on the viewfinder 3 and the variable members 1 and 2 of FIG. Variable member 1,
2 has a hollow inside, and the variable member 2 is housed in the variable member 1 with a slight gap left between it and the variable member 1, and both members are housed inside the video camera body 4.

FIG. 6 is a perspective view of FIG. 5 is a state in which the variable members 1 and 2 of FIG. Is represented.

FIG. 7 shows the variable members 1 and 2. Both the variable members 1 and 2 are thin and hollow inside. Since the inner diameter of the variable member 1 is larger than the outer diameter of the variable member 2, the variable member 2 can be housed in the variable member 1. Further, the variable member 1 is provided with the concave portion 5 and the variable member 2 is provided with the convex portion 6 so that the variable member 2 does not come out from the variable member 1.

As shown in FIG. 8, the concave portion 5 of the variable member 1 is caught by the convex portion 6 of the variable member 2, and the variable member 2 is changed.
I can't get out of it.

As shown in FIG. 9, a wire rod 9 connecting the CRT 7 and the substrate 8 in the viewfinder 3 to the video camera main body passes through the variable members 1 and 2. Further, the fixed piece A10 is attached to the variable member 1, and the convex portion 11 that is caught by the video camera body 4 is provided on the fixed piece A10 so that the variable member 1 does not come out of the video camera body 4.

FIG. 10 shows how the mechanism shown in FIG. 11 rotates. The rotation angle is based on the horizontal state −
It is possible from 90 degrees to +180 degrees.

The variable member 1 is connected by the fixed piece B12 shown in FIG. 11, and the viewfinder 3 is stopped by the moderation plate 13 and the plate spring 14 at an interval of 45 degrees. Further, the viewfinder 3 and the moderation plate 13 are fixed via the fixing piece C15.

[0017]

According to the present invention, the relative position variable member connecting the video camera body 4 and the viewfinder 3 can be housed inside the video camera body 4, which is disadvantageous in appearance. The relative position variable member can be prevented from appearing on the external surface except when necessary.
