Abstract

PURPOSE:To improve the ralation between a camera body and an outer case and to miniaturize a video camera, by forming the outer cover with a middle frame cover and a side cover at both sides, fitting the camera main body of the cover of one side and providing an adjusting window to the side cover of one side. CONSTITUTION:An outer shell member of the camera is constructed as a three- layer constitution with a left side cover 31, a right side cover 32 and a middle frame cover 33 between them and the camera main hody is fitted to the cover 31 at the left side viewed from a lens cover 34. Plural supports 312 are provided at the inside of the cover 31, a fitting hole of a barrel of the main body is screwed with a small screw to fix the main body. Further, a window 311 possible for switching is provided to the cover 31 and the cover 31 fitted with the main body is fixed with a tripod seat fitting section 313. Components on a printed board are adjusted from the window 311 to mainaturize the video camera.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video camera, and more particularly to a small video camera 5'VC in which seven improvements have been made in the relationship and configuration between the camera body and the outer shell member.

In recent years, small video cameras have been developed and become popular.
)is. A small video camera is generally symmetrical when viewed from the front of the camera, and the outer shell of the camera is formed from a molded resin member, a metal plate, a metal die-cast, or the like. When manufacturing a camera, there were many cases in which the camera body, excluding the outer shell 7, was assembled and adjusted, and then the outer shell was completed by cutting the camera body after assembly and adjustment 7. Performing assembly and adjustment with the outer shell members removed allows for assembly and adjustment from all directions of the main body, but on the other hand, it is possible to assemble and adjust the main body from all directions except for the outer shell members. It required structure and strength, and also required a holding part to hold the main body part Z for assembly and adjustment. The outer shell member has a dust-proof effect as well as the outer shell member has the same +T and FVC to prevent it from easily deforming and damaging the main body when the camera is bumped. It was necessary to do so.

An object of the present invention is to provide a video camera which has a structure that eliminates excessive strength and is convenient for assembly and adjustment. This is achieved by a video camera characterized in that the camera body is attached to one side cover.

Hereinafter, the present invention will be explained in detail with reference to FIG. 7. FIG. 1 shows the basic structure of the video camera of the present invention. In FIG. There is a variable magnification lens group that moves back and forth, consisting of the FC, the front group Ml, and the rear group V2 that follow. There is a splitting prism SP that splits the optical path. A part of the light is bent at right angles by the splitting prism 5PIC with a semi-transparent surface installed at an angle of 45''I-', and is imaged on the light receiving surface of the image pickup tube T by the rear lens group for imaging M2. The imaging optical system is -).

Further, a part of the light that is split by the splitting prism P and goes straight ahead is moved to the pupil position by the front and rear finder lens groups F, , F, forming a finder optical system that becomes a finder when placed at the pupil position [EVCIIY]. The optical axes of these optical systems coincide, and 7)
・It is necessary that the lens position is maintained, and the lens barrel member 1 is housed and integrated.

A video camera with such an optical system obtains power from outside the camera through a connector cord 21τ due to the circuit failure shown in Fig. An image signal is obtained by the image signal processing circuit and sent to the video recorder from the external output and the connector (7) to the video recorder. , are attached to the lens barrel member l mentioned above.

FIG. 3 shows that the lens barrel member 1 and the image pickup tube T are connected to the image pickup tube mounting frame 1 (η
It is attached to one body through the , and multiple pieces of pudding are attached to it)! (shown with the plate attached).

ing. The printed circuit board P1 is a base for a high voltage circuit, and is fixed near the image pickup tube T, and is built into the grip of the camera. Furthermore, the outer circle of the lens barrel 1 (SP) of the split prism 82 section has a U-shape [three printed boards P2. P3. It is installed so that P4 covers it. On the printed board P4 on the left side when viewed from the front of the lens, an electrically adjusted adjustment component is provided outside the printed board P4.

FIG. 4 shows an exploded view of the outer shell member of the camera.

The outer shell member has a three-layer structure including side covers on both sides and an intermediate frame cover in between. The left side cover 31 on the left side when viewed from the front of the lens is attached with the main body shown in Figure 3 (J
As shown in the figure, several columns 312 are provided inside the left side cup 31, and the mounting hole 12 of the lens barrel is screwed to the columns 312 using small screws. In this way, the main body shown in FIG. 3 is fixed to the left side cover 31. The left side cover 31 has a tripod mount mounting portion 313 on the bottom surface. When the tripod seat is attached to the tripod seat attachment portion 313, the left side cover 31 can be fixed with the tripod screw.

In addition, the left side cover 31 is provided with a window 311 that can be opened and closed, and the left side cover 31 has a window 311 that can be opened and closed.
is fixed with a tripod mount, and the printed board P4 is inserted from the window 311.
The adjustment parts above can be adjusted.

In the present invention, since there is an intermediate frame cup <-33, when the intermediate frame cover 33 is not attached, the main body in FIG. 3 is almost opened, increasing the effective space and allowing for free assembly and adjustment. .

The intermediate frame cover 33 is 33m+33b+3 as shown in the figure.
3't', but a release switch, an eyepiece, etc. are attached to these intermediate frame covers 33 as a unit. In addition, the electronic befinder mounting seat and tripod mount provided on the center line of the camera connect and fix the left side cover 31, intermediate frame cover 33, and right side cover 32, and the connecting pillar etc. can be omitted. The cover protects the protruding lens part that is installed last during assembly. In this way, a video camera that is easy to assemble and adjust can be obtained with a simple shell structure.

FIG. 5 is a perspective view of the external appearance of the camera, where L is the photographing lens, and the so-called release switch can be pressed while holding the four grips. Also, the v on the top surface
S is a mounting seat for the electronic viewfinder.
