Description

  The present invention relates to a handy type video camera device that is reduced in size and weight, and relates to a handy type video camera device that has good weight balance adjustment and good camera operability.

  A handy type video camera device for broadcasting business is a device used by a photographer on his / her shoulder, and miniaturization and weight reduction are important items for evaluating operability and mobility. While the camera body of the video camera device is becoming smaller and lighter, the imaging lens is required to have higher functions such as a high magnification and wide-angle lens, and the weight ratio of the imaging lens increases with the weight reduction of the camera body. When the imaging lens is attached to the part, the center of gravity as the camera device tends to be biased toward the imaging lens, the balance when the photographer carries the video camera device is extremely bad, and problems arise in operability and stability Yes.

  In the conventional video camera apparatus, as shown in FIGS. 4A and 4B, the imaging lens 2 is mounted on the camera body 1 of the video camera apparatus, and a grip 6 is provided on the upper part of the camera body 1. There is one in which the viewfinder 3 and the shoulder pad 4 provided in the camera body 1 can be moved and adjusted in the optical axis direction (the direction indicated by the arrow). For example, in FIG. 4 is fixed and includes a sliding mechanism that slides the leg frame 7 back and forth with respect to the camera body 1.
