Abstract

PURPOSE:To reduce the vibration of a cylinder delivered to the microphone by providing a microphone holder in which an outer shell to directly support the microphone is formed by a rubber and mounting and dismounting the microphone to/from the rubber holder. CONSTITUTION:This microphone is mounted dismounted to/from rubber holders 1, 2 by providing a microphone holder T in which an outer shell to directly support the microphone is formed by a rubber. Then the microphone holder 7 is arranged to two points at which the microphone is supported, and a throughhole 13 is provided to the mount to the camera recorder main body in the vicinity of the microphone support in a direction in parallel with the axial direction of the microphone. Moreover, a rigid holder is combined to the rubber holders 1, 2 and their outside as duplicate structure and interference is avoided at the inner and outer circumference. Thus, the microphone fitted to the inner rubber holder 1 is supported elastically in the inside of the outer rigid holder and they are not interfered at the circumferential part. Thus, the vibration of the cylinder delivered to the microphone is remarkably reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera and a camera recorder.

[0002]

2. Description of the Related Art A digital VTR developed in recent years has a large number of rotations of a cylinder and a large vibration generated there compared to analog recording. There is a problem that it is recorded at the same time as the transmitted voice.

A conventional microphone mounting device will be described below with reference to the drawings. As shown in FIG. 4, a microphone 19 is attached above the front of the camera recorder. The detailed configuration of the mounting device is shown in FIGS.

First, the front microphone holder is composed of a microphone holder (A) 5 and a microphone holder (B) 6. Both are connected to each other by a spring pin 24 via a washer 25. Further, the microphone holder (A) 5 is fastened to the top surface of the camera recorder with a screw 21, and the microphone holder (B) 6 is rotatable about a spring pin 24 as a fulcrum.

Further, cushions (A) 16 made of sponge are attached to the inner walls of the microphone holder (A) 5 and the microphone holder (B) 6, respectively. The microphone holder screw 20 is attached to the microphone holder (B) 6 and is fixed to the microphone holder (A) 5 when holding the microphone.

On the other hand, as shown in FIG. 5, the rear microphone holder comprises a microphone holder (C) 7 and a microphone holder (D) 8. Both are engaged with each other and screwed together, and are fastened to the top surface of the camera recorder on the side of the microphone holder (C) 7. A connector 1 to which a microphone is connected inside the cylinder of the microphone holder (D) 8.
The microphone 4 is integrated with the microphone jack boss 22 by screws, and is attached by the lid 23 with the cushion (C) 18 interposed therebetween.

A cushion (B) 17 is wound around the outer periphery of the connector 14 and the microphone jack boss 22 and is inscribed in the microphone holder (D) 8.

A procedure for attaching a microphone to the microphone attaching device configured as described above will be described. Loosen the front microphone holder screw 20, open the microphone holder (B) 6, insert the connection terminal of the microphone into the connector 14, close the microphone holder (B) 6, and attach the microphone with the microphone holder screw 20.

[0009]

However, in the above-mentioned conventional structure, the microphone is firmly fixed to the exterior part of the camera recorder body by the microphone holder via the cushion, so that the cylinder rotates at a high speed like a digital VTR. Had the drawback of transmitting the vibration of the to the microphone and being recorded.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a microphone mounting device capable of significantly reducing the vibration of the cylinder transmitted to the microphone.

[0011]

In order to achieve this object, a microphone mounting device of the present invention is a dual microphone in which a microphone having an outer shell for directly holding the microphone is made of rubber and a rigid holder is provided outside the microphone. The structure is such that they are arranged so as not to interfere with each other, and a through hole is provided near the microphone holding portion of the rubber holder.

[0012]

With this structure, the microphone attached to the inner rubber holder is elastically held inside the outer rigid holder, and since it does not interfere with each other in the circumferential portion, the vibration transmitted to the microphone is greatly reduced. be able to.

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

FIG. 1 is a sectional view of a front microphone mounting device according to an embodiment of the present invention. The rubber holder (A) 1 is fixed to the top surface of the camera recorder main body together with the outer holder (A) 3 and does not come into contact with anything other than the mounting portion. A metal spacer 11 is insert-molded in the mounting portion of the rubber holder (A) 1 so that it can be screwed. The rubber holder (A) 1 has an outer peripheral portion opened for attaching a microphone, and a velcro tape 12 is attached in the vicinity thereof so that the microphone can be held.

Further, a through hole 13 is provided between the microphone holding portion and the mounting portion on the top surface of the main body in a direction parallel to the microphone axis direction.

The outer holder (A) 3 and the outer holder (B) 4 are connected by a spring pin as in the conventional example, and the outer holder (B) 4 is rotatable.

FIG. 2 is a sectional view showing the rear microphone mounting device. A metal fitting 15 is insert-molded in the mounting portion of the rubber holder (B) 2, and is fitted with the convex portion of the microphone holder (E) 9 and fixed by screwing. (See Figure 3)
The microphone holder (E) 9 is a microphone holder (C) 7
The microphone holder (C) 7 is fastened to the top surface of the camera recorder.

Inside the rubber holder (B) 2, a connector 14 is attached in the same manner as in the conventional example. The microphone holders (C) 7 are provided with microphone guards 10 having an inner diameter larger than the outer diameter of the rubber holder (B) 2 and are not in contact with each other. This microphone guard 10
Is the outer holder (A) 3 and the outer holder (B) even if the camera recorder is lifted using the microphone as a handle.
4 and protect the rubber holder.

Since the procedure for attaching the microphone is almost the same as the conventional example, the description thereof will be omitted. As described above, according to the present embodiment, by virtue of having a through hole in the vicinity of the microphone holding portion of the holder in which the microphone holding portion is rubber-molded and combining the rigid holder outside the rubber holder, the vibration transmitted to the microphone can be significantly reduced. Can be reduced to

In this embodiment, the microphone holder (E)
Although the method for attaching 9 and the rubber holder (B) 2 is screw fastening, the metal fitting 15 inserted in the rubber holder (B) 2 may be eliminated and both may be bonded.

[0021]

As described above, according to the present invention, the rubber holder for directly holding the microphone has a through hole in the vicinity of the microphone holding portion, and the rigid holder is arranged outside the rubber holder so as not to interfere with each other. By adopting a double structure, it is possible to realize a microphone mounting device capable of significantly reducing vibration transmitted to the microphone.
