Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a camera-hanging type photographing device used for taking a photograph of, for example, a deceased terrain or a terrain from directly above, which is relatively close to the ground, regardless of an aerial photograph.

[0002]

[Prior art]

 Conventionally, as this kind of device, there is a device (Japanese Utility Model Publication No. 62-14448) related to the utility model registration application of the applicant. This invention is composed of a pair of climbing poles standing on the ground, a suspension rope that is erected on the upper ends of the pair of poles and can be loosened from the ground, and can be moved to the suspension rope. The gyro frame, which is mounted on the gyro frame with the camera facing downward, and the pair of operating ropes connected to the gyro frame are roughly configured. It is designed to move the gyro frame.

[0003]

[Problems to be solved by the device]

 By the way, the above-mentioned prior art has the following unsolved problems.

First, since the pole is not configured to be stretchable, the height of the camera is adjusted only by changing the tension of the suspension rope from the ground. Therefore, it is necessary to loosen the rope abnormally or to tighten it conversely, which puts excessive force on the pole and rope and makes height adjustment troublesome. Also, since the pole is long, it is not portable.

Secondly, since the gyro frame is not rotatable in the horizontal direction, it is impossible to change the camera horizontally or vertically depending on the object to be photographed. For this reason, it was not possible to shoot efficiently, it took time to shoot, and film was wasted.

Thirdly, since there is no means for accurately measuring the amount of movement of the camera and visual observation is performed from the ground, the efficiency of the photographing work is poor and it is difficult to photograph without waste.

Fourth, since the moving pulley is engaged with the suspension rope in advance when the device is assembled, the workability of the assembly is poor, and even if the gyro frame is replaced for some reason, It could not be replaced easily.

Fifth, since a means for easily measuring the height of the camera is not provided, the length is measured from the ground with a long measuring rod, but workability is poor and accuracy is lacking.

The present invention has been made in view of the above-mentioned problems of the prior art. The height and direction of the camera can be freely set, and the camera can be accurately moved from the ground by a desired distance. The purpose of the present invention is to provide a camera-hanging type imaging device that can be operated and is excellent in portability.

[0010]

[Means for Solving the Problems]

 The means of the present invention configured to solve the above-mentioned problems is configured to be expandable and contractable, and a pair of poles that are erected on the ground while being separated from each other by a predetermined distance and the above-mentioned poles on the upper end side of the pair of poles. A camera support having a supporting long member that is laid loosely from the ground and a camera deck that can rotate in the horizontal direction, and is movably supported by the supporting long member, and one end side of each of the camera supports. A pair of traction ropes, the other end of which is hung along the pair of poles by being connected to the camera support and being guided by a guide member provided on each of the poles, and the tension of each suspension rope. And a camera movement amount measuring unit provided on the lower side of each of the pair of poles so as to measure the movement distance of the camera support according to the amount.

Further, it is preferable that the support carriage constituting the camera support body is composed of a base and a chassis that are detachable from each other.

Further, a height measuring member made of a thin wire may be vertically installed on the camera deck with a length reaching the ground.

[0013]

[Action]

 The pole is adjusted by expanding and contracting according to the terrain to be photographed and the height of the camera, and it is installed on the ground. When suspending the camera support on a long support material, rotate the camera deck according to the shooting target and set vertical shooting or horizontal shooting. The camera can be moved in the desired direction by pulling down one of the pair of tow ropes. The pull amount of the tow rope is measured by the camera movement amount measurement unit, and the camera is accurately positioned.

Further, the chassis and the base are detachable, and the camera support is engaged with the supporting long member.

The height of the camera is measured by reading the scale at the portion where the height measuring member hung from the camera deck contacts the ground.
