Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a viewfinder for a video camera.

<Prior Art> A viewfinder of a conventional video camera will be described with reference to FIGS. 7 and 8.

FIG. 7 is a front view of a viewfinder of a conventional video camera, and FIG. 8 is a sectional view taken along the line B--B in FIG.

The viewfinder is used by the user to check the video being recorded by the video camera, and is movable to accommodate shooting conditions (1) such as the physique and angle of the photographer. ing.

This viewfinder includes a microphone section 120 provided with a microphone 121, a monitor section 220 rotatably supported by the microphone section 120, an eyepiece section 230 connected to the monitor section 220, and an eyepiece section 230 connected to the microphone section 120. The slider 110 attached to the section 120, the monitor section 220, and the eyepiece section 23
0, and a holding part 300 that rotatably holds a substantially cylindrical neck part 210 formed between the holding part 300 and the holding part 300.

It is slidably attached to a guide rail 410 provided on the video camera body 400 so that it can be moved laterally, and it can be freely rotated in the vertical direction between the microphone section 120 and the monitor section 220.

The holding part 300 is provided for reinforcement in view of the fact that the point of effort (corresponding to the eyepiece part 230) and the fulcrum (corresponding to the space between the microphone part 120 and the monitor part 220) are far apart during rotation. It is made up of a holder 310 that holds the neck portion 210 from below, and a substantially semicircular ring 320 that holds the holder 310 from above.

The holder 310 has a curved recess 3 for receiving the neck 210.
11 is formed, and a screw 31 is attached to the slider 110.
It can be installed in 5. On the other hand, at both ends of the ring 320,
A mounting portion 322 is formed, and a screw 3 is inserted so as to hold the neck portion 210 received in the curved recess 311 from above.
It is attached to the holder 310 at 23.

Therefore, the monitor section 220 and the eyepiece section 230 are connected to the neck section 21.
It is held at 0.

<Problems to be Solved by the Invention> However, the above-mentioned video camera viewfinder has the following problems.

That is, the ring 320 and the holder 310 connect the neck 210.
A jig must be used to hold the
Work efficiency is poor. Furthermore, the screws 323 at the attachment portion between the ring 320 and the holder 310 are visible from the front, which is unsightly.

The present invention was devised in view of the above circumstances, and an object of the present invention is to provide a viewfinder for a video camera that is efficient in holding the neck and has an excellent design.

Means for Solving the Problems> The viewfinder of a video camera according to the present invention includes a slide portion that can freely slide with respect to the video camera body, and a rotating portion that is rotatably supported by the slide portion. ,
A viewfinder for a video camera having a holding part that rotatably holds a neck formed on the rotating part, wherein the sliding part is a slider that is slidably fitted into a guide rail provided on the video camera body. The holding portion is attached to the slider and has a holder formed with a curved recess for receiving the neck, and a substantially Ω-shaped ring for holding the neck received in the curved recess, A claw portion corresponding to the engaging portion formed in the curved recess is formed at one end of the ring, and the neck portion is held by engaging the claw portion with the engaging portion.

<Effect> The holder of the holding section is attached to the slider with screws.

At this time, the curved concave portion of the holder receives the neck portion of the rotating portion from below. Attach the ring from above the neck received in the curved recessed part.

In other words, attach the mounting part of the ring to the holder with screws,
The claw portion of the ring is engaged with the engaging portion.

The neck is now rotatably held by the holding section consisting of the holder and the ring.

<Example> Hereinafter, an example according to the present invention will be described with reference to the drawings.

Fig. 1 is an exploded perspective view of a viewfinder of a video camera according to an embodiment of the present invention, Fig. 2 is a perspective view of a holder, Fig. 3 is a side view of the video camera to which this viewfinder is attached, and Fig. 4 The figure is a front view of the video camera, FIG. 5 is a sectional view taken along line AA in FIG. 4, and FIG. 6 is a perspective view of the viewfinder from the rear.

The viewfinder of the video camera according to the present embodiment includes a slide portion I00 that is slidable with respect to the video camera body 400, a rotating portion 200 that is rotatably supported by the slide portion 100, and a rotating portion I00 that is rotatably supported by the slide portion 100. The slide section 100 has a holding section 300 that rotatably holds a neck section 210 formed on the section 200, and the slide section 100 has a slider 110 that is slidably fitted into a guide rail 410 provided on a video camera body 400. and the holding part 30
