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 larger number of rotations of a cylinder than an analog recording, and the vibration generated there is also large. There is a problem that the sound is transmitted and recorded at the same time.

A conventional microphone mounting device will be described below with reference to the drawings. As shown in FIG. 4, a microphone 19 is attached to the upper front of the camera recorder. 5 and 6 show the detailed configuration of the mounting device.

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. The microphone holder (A) 5 is fastened to the top surface of the camera recorder by screws 21, and the microphone holder (B) 6 is rotatable around the spring pin 24 as a fulcrum.

Further, sponge cushions (A) 16 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. 6 , the rear microphone holder comprises a microphone holder (C) 7 and a microphone holder (D) 8. Both are engaged with each other and are screwed together, and are fastened to the top surface of the camera recorder on the microphone holder (C) 7 side. A connector 1 to which a microphone is connected inside the cylinder of the microphone holder (D) 8
4 is integrated with the microphone jack boss 22 by screwing, and attached by the lid 23 with the cushion (C) 18 interposed therebetween.

[0007] 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 having the above-described configuration will be described. The microphone holder screw 20 in the front is loosened, the microphone holder (B) 6 is opened, the connection terminal of the microphone is inserted into the connector 14, the microphone holder (B) 6 is closed, and the microphone is attached with the microphone holder screw 20.

[0009]

However, in the above-mentioned conventional configuration, since the microphone is firmly fixed to the camera recorder body outer portion by the microphone holder via the cushion, the cylinder rotates at a high speed like a digital VTR. Vibration is transmitted to the microphone, and is further recorded.

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

[0011]

In order to achieve this object, a microphone mounting device according to the present invention is applied to a camera recorder.
A rubber molded rubber holder attached to hold the microphone
Is arranged via a space outside the rubber holder
Together with the camera recorder, and is rigid and
And a rigid holder formed.

[0012]

With this configuration, the microphone attached to the inner rubber holder is elastically held inside the outer rigid holder, and the microphone and the rigid holder are connected to each other.
Because there is a space between them, they do not interfere with each other, so
Vibration transmitted from the camera recorder to the microphone can be greatly reduced.

[0013]

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. 1 is a rubber hol
(A), an annular ring that holds a cylindrical microphone
Microphone holder and one ring outside of the microphone holder
It has a mounting part that protrudes toward
Have been. Rubber holder (A) 1 is outer holder (A) 3
Together with the top of the camera recorder,
There is no contact except at the mounting part. Rubber holder (A) 1
The metal spacer 11 is insert-molded in the mounting portion of the above, and can be screwed. The rubber holder (A) 1 has an outer peripheral portion opened for mounting a microphone, and a magic tape 12 is affixed in the vicinity thereof to hold the microphone.

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 constituting the rigid holder are connected by a spring pin as in the conventional example, and the outer holder (B) 4 is rotatable. Also use a microphone as a handle
Excessive force on the microphone, as if lifting the
If added, the microphone and rubber holder are rigid
Because the range of movement is limited inside the holder, the microphone
Detachment from the Mera recorder or damage to the rear mounting part of the microphone
Can be prevented.

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 to the convex portion of the microphone holder (E) 9 and fixed by screwing. (See Fig. 3)
The microphone holder (E) 9 is a microphone holder (C) 7
And the microphone holder (C) 7 is fastened to the top surface of the camera recorder.

A connector 14 is mounted inside the rubber holder (B) 2 in the same manner as in the prior art. A microphone guard 10 having an inner diameter larger than the outer diameter of the rubber holder (B) 2 is attached to the microphone holder (C) 7 and does not contact each other. This microphone guard 10
Means that the outer holder (A) 3 and the outer holder (B) can be
Together with 4, protect the rubber holder.

The procedure for attaching the microphone is almost the same as that of the conventional example, and the description is omitted. As described above, according to the present embodiment, the microphone holder is formed of a rubber holder formed of rubber .
By having a through hole near the mounting portion to the camera recorder and combining a rigid holder via a space outside the rubber holder, vibration transmitted from the camera recorder to the microphone can be significantly reduced. I also need a microphone
When the camera recorder is lifted in place of a handle
Even if excessive force is applied to the microphone,
And the rubber holder can be moved inside the rigid holder
Microphone is disconnected from the camera recorder
And damage can be prevented.

In this embodiment, the microphone holder (E)
Although the method of mounting the rubber holder 9 and the rubber holder (B) 2 is screwed, the metal fitting 15 inserted into the rubber holder (B) 2 may be omitted and both may be bonded.

[0021]

As described above, the present invention has a through hole near the microphone holding portion of the rubber holder for directly holding the microphone, and the rigid holder is arranged outside the rubber holder so as not to interfere with each other. By using a double structure, a microphone mounting device capable of greatly reducing vibration transmitted to the microphone can be realized.
