つた小型のビデオカメラに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video camera, and more particularly to a small-sized video camera in which the relationship and structure between the camera body and the outer shell member are improved.

に、ビデオカメラは、コンパクトに構成する事が
出来ないという欠点を有していた。 In recent years, small video cameras have been developed and become popular. In a conventional video camera, a camera body consisting of a lens barrel and a board is attached to a chassis, and an exterior side cover is attached to the chassis.
As a result, the chassis is assembled first, the lens barrel and circuit board are adjusted, and then the exterior cover is attached, which has the advantage that the camera body can be adjusted from all directions. The advantage is that even if the side cover of the camera breaks, the camera body will not break due to the rigidity of the chassis. On the other hand, since the above configuration has a built-in chassis, the video camera has the disadvantage that it cannot be configured compactly.

いう欠点を有していた。 In addition, as a different method, attempts have been made to make the entire video camera more compact by omitting the chassis by making the exterior side cover stronger and attaching the lens barrel and board directly to the exterior side cover. However, this configuration has the disadvantage that when assembling the video camera, the lens barrel and the board can only be adjusted from one side cover side.

ラにより達成された。 The object of the present invention is to provide a video camera having a structure that eliminates excessive strength and is convenient for assembly and adjustment. This has been achieved with a video camera configured such that another side cover is attached to the side cover while covering the camera body, and the side cover serves as an exterior.
以下、図面を用いて本発明の詳細な説明を行な
う。 Hereinafter, the present invention will be explained in detail using the drawings.

撮像光学系となつている。 FIG. 1 shows the optical system of a video camera according to the present invention. In the figure, there is a focus lens group FC that moves back and forth for focusing, and a variable power lens group that moves back and forth, consisting of a front group V1 and a rear group V2 . Next, there is a front group lens M1 for imaging, and a splitting prism SP that divides the optical path into an imaging system and a finder system. A part of the light is bent at right angles by the splitting prism SP with a semi-transparent surface set at an angle of 45 degrees, and the image is formed on the light-receiving surface of the image pickup tube T by the imaging rear group lens M2 . It serves as an imaging optical system.

ている。 Further, a part of the light that is split by the splitting prism P and goes straight ahead is formed into a finder optical system in which the front and rear finder lens groups F 1 and F 2 act as a finder when the eye is placed at the pupil position E. These optical systems require that their optical axes coincide and that the relative lens positions are maintained, and are housed in the lens barrel member 1 and integrated.
