JPH11168784A - Microphone holder mechanism for video camera - Google Patents

Abstract

PROBLEM TO BE SOLVED: To cope with multifarious microphones on the market by one microphone holder, without having to lope with them by many microphone holders in coping with them for the microphone holder of a video camera device. SOLUTION: This mechanism is constituted of a first clamping metal fitting 1, a second clamping metal fitting 2, a shaft 5, a knob 4 for moving the shaft and the knob 3 for fixing and a lower holder and the knob 4 for moving the shaft are provided with screws. Thus, the shaft 5 is vertically moved and the microphones of various diameters are fixed and held.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microphone holder for a video camera.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional microphone holder presses a shaft 5 for opening and closing fulcrum into a first clamp 1 or a second clamp 2 and opens or closes one of the clamps. It has become. At this time, the diameter of the microphone that can be supported is about ± 1 mm of the design value. To support other microphones, a new one with a different diameter (size) of the clamp is prepared as an option. It corresponds. That is, two or more types of microphone holders were prepared.

[0003]

In the above-mentioned prior art,
It is necessary to manufacture two or more types of microphone holders, which is very disadvantageous in terms of mold cost and unit cost. In addition, it takes time to replace the microphone holder after delivery to the customer. Therefore, an object of the present invention is to eliminate the above-mentioned problem and to use one type of microphone holder to accommodate microphones of various diameters.

[0004]

In order to achieve the above object, according to the present invention, a screw feed mechanism is provided in the lower holder, and a knob is provided here. When the knob is closed, the shaft for the opening / closing fulcrum moves upward. Move and clamp the larger microphone. Also, by loosening the knob, the shaft can be moved downward and a smaller microphone can be inserted and fixed.

[0005]

FIG. 1 is a view showing the structure of the present invention, in which a first clamp 1, a second clamp 2, a knob 3, a knob 4, a shaft 5, a spacer 6, a screw 7,
It consists of a microphone 8. FIG. 4 shows an enlarged cross section of a portion of the microphone holder including the knob 4, the shaft 5, the spacer 6, and the like.

An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a front view of this embodiment, showing a state in which a thin φ19 microphone 8 is installed among commercially available products. The knob 4 that penetrates the inside of the shaft 5 connecting the first clamp 1 and the second clamp 2 and engages with the screw portion provided on the second clamp 2 sandwiches the spacer 6, The screw 7 prevents the shaft 5 from coming off. With this configuration, the upper holder is opened and closed with the shaft as a fulcrum, the microphone 8 is installed, and the knob 3 is fixed and held. Here, at the shaft 5 mounting portion of the second clamp 2, the shaft 5 moves up and down, so that the shaft 5 has a U-shaped shape to guide the shaft 5. The same effect can be obtained not only in a U-shape but also in an oval shape.

In FIG. 1, the knob 4 is located below, and the thin microphone (φ19) is fixed and held. In FIG. 2, the knob 4 is moved upward, the fulcrum is moved, and the thick microphone (φ2) is moved.
5) shows the place where is fixedly held.

[0008]

According to the present invention, it is possible to deal with a variety of microphones (different diameters) with a single microphone holder, instead of using multiple microphone holders.
