Description

  The present invention relates to a close-up assisting tool that enables close-up photography of a distant subject with a photographing apparatus.

  For example, some power facilities such as balancers and transformers are installed at high places such as the upper part of a power pole. In order to investigate the nameplates of power equipment installed in high places and to check details, we used binoculars from the ground or climbed to a power pole to check.

  However, when confirming with binoculars from the ground, it is necessary to use high-magnification binoculars, which may not be clearly visible due to camera shake. In addition, since confirmation is performed by looking upward from the ground, the field of view is blocked and it is difficult to visually recognize the position depending on the position of the confirmation target. In addition, when confirming by ascending a tower to a utility pole or the like, it takes time and labor, so that the places that can be confirmed within a predetermined time have been limited. Furthermore, since training is required to climb the tower to the utility pole, the number of workers has been limited.

  By the way, some of the work related to the electric power equipment being energized is performed by an indirect hot wire method using an electric insulating rod called a common operation rod. Various tools can be attached to the tip of the common operation rod, and the tool to be attached can be changed according to work. According to this indirect hot wire construction method, it is possible to safely work from the ground even if the power facility is energized attached to a high place such as a utility pole or electric wire.

  In addition, a technique related to a camera support suitable for fixing a camera to a pipe material is known (see Patent Document 1).

  However, since the nameplate is a small part in order to check the details of a high place with a camera, it is necessary to photograph the nameplate sufficiently close to the nameplate as a subject. Further, the close-up possible distance varies from camera to camera. When the distance is too close, the focus is not achieved. When the distance is too far, the characters on the nameplate are unclear. Furthermore, if the camera cannot be held in a stable posture, the image becomes unclear due to camera shake. That is, even if a camera is installed on a long pole material (number of meters in height) by the camera support tool described in Patent Document 1, the tip of the pole is supported while the long pole material is supported. It was very difficult to keep supporting the camera at close-up distance.
