Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a television camera holder that is attached to a handheld television camera that can be carried on the shoulder of a photographer to take pictures outdoors. It is something.

[Prior Art] There are two types of television cameras: those that are installed in a studio, etc., and those that can be brought into the filming location.TV cameras for filming on-site filming are also supported on a tripod, etc. There are large models and handheld models that the photographer carries on his or her shoulder. Here, a hand-held television camera is equipped with a shoulder rest at the bottom of the camera, and a grip near the tip of the camera for the photographer to hold in his hand and perform various operations. have been used traditionally. The lens can be detachably connected to the camera via a bayonet mechanism.

[Problems that the invention aims to solve] By the way, in order to improve the image quality of images and to be able to use advanced shooting techniques, the lenses attached to cameras must also be large and complex. It is necessary to use a structure. However, when such a large lens is used in a hand-held television camera, the following problems arise.

First of all, as a lens becomes larger, it inevitably becomes heavier, so if the lens is fixed to the camera using only the bayonet mechanism as described above, this puts a heavy burden on this bayonet mechanism, and during long-term use, In this case, the bayonet mechanism is deformed, causing a misalignment between the optical axis of the lens and the optical axis of the camera.

Secondly, if the lens becomes heavier, the center of gravity of the television camera will shift to the front, and for this reason, if the camera is equipped with a grip, it becomes impossible to balance the weight, and the television camera Another drawback is that a large force is applied in a direction that causes the front of the camera to tilt downward, which places an extremely large burden on the photographer.

Third, the optimal grip mounting position for a TV camera depends on the physique of the person taking the picture.
The grip differs depending on the person's preference and shooting posture, and if the grip was fixedly attached to the camera, it would not be possible to change the position of the grip depending on the photographer. It also has the disadvantage of poor operability.

The present invention was developed in view of the above points, and its purpose is to make it possible to use a large lens and to improve the operability of a television camera equipped with such a large lens. To provide a holder for a handy-type television camera that can be used to hold a TV camera.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a camera fixing part for fixing a camera, and a lens attaching part for attaching a lens, and there is a gap between the camera and the lens. It has a support plate that is installed to support the lens, and a grip that allows the photographer to hold and operate the camera while carrying the camera, and the grip can be repositioned to the support plate via a support rod. Its feature is that it is configured to be connected to.

[Function] Since the support plate is installed between the camera and the lens, and the lens can be supported by the support plate, no burden is placed on the bayonet mechanism that connects the camera and the lens. Therefore, even if a large and heavy lens is used, there will be no inconvenience such as deformation of the bayonet mechanism. Furthermore, since the position of the grip can be changed, the grip can be placed at the optimal position for photographing according to the photographer's physique, preferences, photographing posture, etc.
In particular, since this grip is attached to a support rod, by sliding the grip along the support rod, the grip can be placed in a position that provides a good weight balance between the lens and the camera. As a result, the burden on the photographer can be reduced, and the operability of the television camera is significantly improved.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

First, FIGS. 1 to 3 show the entire television camera. In the figure, 1 is a camera, 2 is a lens, and the camera 1 and lens 2 can be detachably connected by a bayonet mechanism using a bayonet ring 3. and,
A shoulder rest part 4 is formed in the camera 1 by recessing a curved part in the bottom part thereof.

Next, as is clear from FIG. 3, a support plate 10 is installed between the camera 1 and the lens 2. The support plate 10 has a camera fixing part 10 whose one end is fixed to the camera 1 with a fixing means such as a screw.
A lens mounting portion 10b is formed at the other end to which a threaded rod 12 connected to a female threaded portion 11 provided on the lens 2 is mounted. In addition, support plate 1
A locking portion 13 for mounting and locking on a tripod is provided on the lower surface of the camera fixing portion 10a at 0.

Furthermore, as shown in FIG.
A connecting plate portion 14 is erected on one side of the connector 0, and a female screw portion 14a is formed in the connecting plate portion 14. Then, with a mounting member 16 integrally provided on the support rod 15 in contact with the connecting plate portion 14, the screw 17 is inserted into the insertion hole 16a formed in the mounting member 16. By screwing into the female threaded part 14a of 14, the support rod 15
can be fixed in a connected state to the support plate 10. A slide mount 18 is inserted through the support rod 15, and the slide mount 18 has an insertion hole 19 for the support rod 15, and a split 20 in the axial direction of the insertion hole 19. Furthermore, a screw insertion hole 2 is formed in the plate thickness direction in the portion where this split 20 is formed.
1 is drilled. A grip 22 is connected to the slide mount 18 and fixed with a screw 23. Also, this screw 23
This allows the slide mount 18 to be fixed to the support rod 15. Furthermore, the grip 22 is provided with a zoom operating mechanism 24, which is connected to the camera 1 through a wiring connector 25. Note that 26 in the figure is a belly pad attached to the support plate 10.

This embodiment is constructed as described above, and its operation will be explained next.

First, to assemble the television camera, the camera 1 and the lens 2 are connected together via the bayonet ring 3. Then, the support rod 1 with the grip 22 attached to the connecting plate portion 14 of the support plate 10
5 is attached, the camera fixing part 10a of the support plate 10 is fixed to the camera 1, and the lens attaching part 10b is screwed into the threaded part 11 of the lens 2 with the threaded rod 12. A support plate 10 is installed between the lens 2 and the lens 2 to support the lens 2. This prevents the load of the lens 2 from being applied to the bayonet mechanism between the lens 2 and the camera 1, so even if a large and heavy lens 2 is used, the bayonet mechanism will not be deformed. There is nothing to do.

Here, the position of the grip 22 connected to the support plate 10 via the support rod 15 can be changed, and the position of the grip 22 can be changed as follows. become.

First, in order to change the position of the grip 22 in the height direction, it is sufficient to loosen the screw 17 and rotate the support rod 15 about the screw 17 in the direction of arrow A in FIG. Then, when the grip 22 is at a desired height position, the screw 17 is tightened again to fix the grip 22.

Next, to change the position of the grip 22 in the front-back direction, loosen the screw 23 and move the slide block 18 along the support rod 15.
can be moved in the direction of arrow B in FIG. It goes without saying that the grip 22 can be fixed in that position by tightening the screw 23. In particular, being able to move the grip 22 in the front-back direction means that the grip 22 can be moved by its weight according to the displacement of the center of gravity when the camera 1 and the lens 2 are connected or when an accessory or the like is attached. This allows you to move it to a balanced position.

Furthermore, with the height position and front and rear positions of the grip 22 changed and adjusted as described above,
To adjust the orientation of the grip 22, loosen the screw 23 and rotate the slide block 18 about the support rod 15, then move the grip 22 left and right as shown by arrow C in FIG. It can be tilted to Also, slide block 18
If the grip 22 is fixed and rotated back and forth about the screw 23, the grip 22 can be tilted back and forth as shown by arrow D in FIG. By tilting the grip 22 back and forth and left and right, the grip 22 can be held and operated most easily by the photographer.

As a result, the position of the grip 22 can be adjusted depending on the photographer's physique, preferences, shooting posture, etc., so that the grip 22 can be held in the best possible position while the shoulder rest 3 of the camera 1 is carried on the photographer's shoulder. It becomes possible to displace it to an easy position, and it becomes possible to reduce the burden on the photographer.

[Effects of the invention] As explained above, according to the invention, by installing the support plate between the camera and the lens, the weight of the lens can be supported by the support plate. Because of this structure, even when a large and heavy lens is attached, there is no problem of deforming the bayonet mechanism that connects the lens and the camera, and the position of the grip can be changed via the support rod. Since the grip is connected to the support plate, the photographer can move the grip to the position where it is most convenient to hold and operate while carrying the camera on his or her shoulder, greatly improving operability during shooting. It has various effects such as improving the condition.
