Description

[Detailed Description of the Invention] The present invention relates to a microphone holding mechanism suitable for use when a microphone is integrally attached to the main body of a cine camera or the like.

Conventionally, in simultaneous recording type cine cameras, the microphone was separated from the camera body to prevent the microphone from picking up mechanical noise such as film feeding sound and motor drive sound generated by the camera during shooting, and to prevent the microphone from picking up camera vibration sound. A method in which it is installed separately and connected to the camera body using a jack connection.However, with this method, it is troublesome to handle, and it is difficult to avoid losing or misplacing it, so it is necessary to eliminate such problems. For this reason, recent efforts have been made to add anti-vibration holding mechanisms to microphones so that camera vibrations are not directly transmitted to the microphone, and technical ideas have emerged to mount the camera body and microphone as one unit.

As a vibration-proof holding structure for a microphone, for example, a pipe with a microphone at its tip is fitted into a cylindrical elastic body.
There is a method in which the pipe is fixed using a retaining ring, but this type of structure has the drawbacks of being complicated, expensive, and difficult to assemble.

In view of these points, it is an object of the present invention to provide a holding mechanism for a microphone in a cine camera, etc., which is inexpensive and can prevent vibrations of the camera body from being transmitted to the microphone.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a microphone including a built-in rod microphone (not shown), and 2 is a pipe.

The pipe 2 is made up of a plurality of pipes with different diameters and moderate lengths, which are joined together with moderate loose fit one after another, one after another, from one pipe with a narrow diameter to the next thinner pipe, and the microphone 1 is attached to the tip of the pipe 2. By expanding and contracting the pipe 2, it is possible to approach the camera body and to separate it appropriately.

Reference numeral 3 denotes a microphone case that mainly houses the pipe 2, contact pin 4, etc. described above, and is formed by screwing a microphone case cover 6 to a microphone case base 5 with screws 7 or the like.

Spaces are provided in the case to accommodate cushion members 8, 8 such as sponges at locations located near the front and rear ends of the pipe 2 housed in the microphone case 3, and the cushion members 8, 8 disposed at the locations are provided in the case. The pipe 2 is held through the pipe 8.

Near the rear end of the pipe 2 inside the microphone case 3,
A board 9 is provided which also serves as a panel to which the wiring between the contact pin 4 electrically connected to the camera body and the microphone 1 is soldered.

Further, a fitting hole 2a is provided in the rear end of the pipe 2 in the radial direction of the pipe 2, and a pin 10 is fixed to the fitting hole 2a by press fitting or the like.

On the other hand, the aforementioned substrate 9 is provided with a hole 9a, and the pin 10 is passed through the hole 9a via an elastic body 11 such as rubber, as shown in FIG.

Furthermore, a groove 12 is provided at the bottom of the microphone case 3 for integrally attaching the camera and the microphone.

At this time, the ends 12b, 12 of the groove are attached to the central part 12a of the groove.
Make the groove width slightly narrower than b.

This is to improve the tightness of the fit between the camera body and the microphone and to eliminate looseness between the two.

Note that 13 is a microphone cover. The above is the configuration of the present invention. When the microphone with the holding mechanism of the present invention is attached to a cine camera, etc., the pipe with the microphone at the tip is held in the microphone case via the cushioning material, so the vibrations of the cine camera are transmitted to the microphone. It is possible to prevent the information from being transmitted.

In addition, a pin is provided on the pipe in the radial direction of the pipe, and the pin is passed through a hole in the board inside the microphone case via an elastic body, which prevents the microphone from coming off, and at the same time prevents vibrations from cine cameras, etc. It serves the function of making it possible.

Furthermore, since the shape of the groove of the retaining part that is integrally attached to a cine camera, etc. is made slightly narrower in the center than on both ends, the microphone is firmly attached to the cine camera, and the microphone does not fall out from the cine camera, etc.
