Abstract

PURPOSE:To prevent accessory parts from being bulky, and to make a video camera easy to carry by providing a grip attached to the lower part of a video camera main body with a driving device for the panning and the tilting operations of the video camera main body. CONSTITUTION:The video camera whose grip part 16 is made vertical is fixed to a tripod 66 through the revolving shaft 60 of the grip part 16, and in this state, the video camera main body 10 is panning-operated by a panning device 20 in the grip part 16, and tilting-operated by a tilting device 18 in a mount 14. Accordingly, the video camera is panning-operated or tilting-operated as being fitted directly on the tripod 66 through the grip part 16, and it is unnecessary to carry a motored universal head. Besides, since the panning device 20 and the tilting device 18 are built in the grip 12, the volume of the video camera main body 10 and the grip 12 is the same as before. Thus, the video camera can be easily carried without making it bulky.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video camera, and particularly to a video camera provided with a grip for improved operability.

[Conventional technology]

Video cameras have traditionally been equipped with grips to improve operability during shooting. Additionally, most grips are foldable and can also be used as handles when carrying.

By the way, conventional video cameras are panned or tilted by an electric panhead device mounted on a tripod. In a video camera having a grip, a mounting portion for the electric pan head device is formed on the grip, and the video camera is structured to be fixed to the electric pan head device via the grip.

[Problem that the invention seeks to solve]

However, in such conventional video cameras, it is necessary to carry accessories such as an electric pan head device, a tripod, and a tripod, so there is a problem that the camera is bulky when carried.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a video camera that does not require bulky accessories when carried.

[Means for solving problems]

In order to achieve the above object, the present invention is a video camera having a grip, and is characterized in that a drive device for at least panning or tilting the video camera body is provided in the grip.

[For f]

According to the video camera according to the present invention, a drive device for panning or tilting the video camera body is provided within the grip to improve the operability of the video camera. Conventional video cameras had hollow interiors within their grips, but with this type of device, the capacity of the video camera and grip remain the same, and the accessory electric pan head device is no longer required, making the video camera less bulky. You can carry it around without having to worry about it.

〔Example〕

Preferred embodiments of the video camera according to the present invention will be described in detail below with reference to the accompanying drawings.

FIGS. 1A and 1B are side views of a video camera according to the present invention. As shown in Figure 1, the video camera body l
A grip 12 is attached to the bottom surface of O.
is composed of a mounting base 14 and a grip portion 16. Grip part 1
6 is rotatably attached to the shaft 17 of the mount 12, and when operating the video camera, the longitudinal direction of the grip 16 is placed slightly tilted forward as shown in FIG. 1(A). When stored, the longitudinal direction of the grip portion 16 is arranged along the lower surface of the main body 10, as shown in FIG. 1(B).

As shown in FIG. 2, the mount 14 is formed of a casing, and a tilt device 18 for tilting the camera body 10 is provided inside. A drive motor 20 of the tilt device 18 transmits rotation to a pulley 24 via a belt 22. The rotation of the pulley 24 is transmitted to the gear 38 fixed to the shaft 17 via the worm 26, gear 28, gear 30, small gear 32, gear 34, and small gear 36. Further, when the grip portion 16 is placed in a state substantially perpendicular to the main body 10 (the grip portion state shown in FIG. 2), the grip portion 16 is fixed to the shaft 17 in a non-rotatable manner. Therefore, when the grip portion 16 is fixed and the motor 20 is driven, the mounting base 14 and the video camera body 10 rotate about the shaft 17. The rotation of the motor 20 and its rotation direction are controlled by a control switch (not shown).

The grip portion 16 is formed to have a hollow interior, and the bread device 40 is disposed inside the grip portion 16 . Drive motor 42 of the pan device 40
rotates the pulley 46 via the transmission belt 44. The rotation of the pulley 46 is controlled by gears 48 to 50. small gear 5
2, and the gear 54. The coaxial worm 56 of the gear 54 meshes with a gear 58, and the gear 58 is fixed to a rotating shaft 60, which is rotatably attached to a bottom opening 62 of the grip portion 16. A mounting hole 6 is provided on the bottom of the rotation shaft 60.
4 is formed, and a fixing screw for a tripod or the like is screwed into the mounting hole 64. Therefore, the rotating wheel 60 is fixed to a fixing screw of a tripod or the like, and when the drive motor 42 of the pan device 40 is driven, the worm 56 rotates and the grip portion 16 rotates about the rotating shaft 60. As a result, the mounting base 14 and the video camera main body lO are rotated. Note that the drive motor 42 of the pan device 40
The rotation and direction of rotation are controlled by a control switch (not shown).

According to the video camera configured as described above, during shooting, the grip portion 16 is operated while being tilted forward at a predetermined angle with respect to the camera body 10, as shown in FIG. 1(A). Further, when the video camera is stored, the grip portion 16 is placed along the video camera body 10 as shown in FIG. 1(B).

Next, when the video camera is to be panned or tilted, the grip portion 16 of the video camera is made vertical, and the video camera is fixed to a tripod 66 via the pivot shaft 60 of the abutment portion 16, as shown in FIG. In this state, the video camera body 10 is held at the grip portion 16.
Panning is performed by a panning device 20 within the mount 14, and tilting is performed by a tilting device 18 within the mount 14.

Therefore, the video camera is directly connected to the tripod 6 via the grip 16.
6 for panning or tilting operation, and there is no need to carry an electric pan head device like in the past. Further, since the panning device 20 and the tilting device 18 are built into the grip 12, the capacities of the video camera body 10 and the grip 12 are the same as in the conventional case.
