Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device suitable for application to, for example, a video camera.

[0002]

2. Description of the Related Art Conventionally, in an electronic device such as a video camera, a plurality of side plates are joined by screws to assemble,
Alternatively, screws are often used for assembly by fixing the casing to the internal circuit component side using screws.

In this case, when the screw is screwed from the outside of the housing, in order to prevent the head of the screw from protruding from the housing, a recess such as a counterbore is provided around the screw insertion hole of the housing. The head of the screw was set in the recess.
For example, FIG. 5 is a diagram showing an example of assembling the side plate and the bottom plate constituting the housing by screwing with a screw, and the recess 3 is provided around the screw insertion hole 2 provided in the side plate 1. on the other hand,
The bottom plate 4 side is provided with a screw insertion hole 5 that is screwed into the screw 6.
The side plate 1 and the bottom plate 4 are fixed by screwing the screw 6 inserted from the concave portion 3 side of the side plate 1 into the screw insertion hole 5.
It is assembled as a housing. In this case, the head 7 of the screw 6
Fits in the recess 3, so the screw 6 does not protrude from the side plate 1,
The head 7 of the screw 6 does not interfere with the use of the electronic device.

[0004]

However, when the recess for accommodating the head of the screw is provided around the screw insertion hole in this manner, at least only around the screw insertion hole, the housing is higher than the height of the head of the screw. It is necessary to increase the thickness of the plate that forms the body so that the recesses can be formed satisfactorily, which disadvantageously increases the thickness of the plate that forms the housing. That is, in the case of the example of FIG. 5, it is necessary to set the thickness t of the side plate 1 to a value larger than the depth of the recess 3 at least only around the screw insertion hole 2.
With this configuration, the inside of the housing is narrowed by the amount of the recessed head portion of the screw, and the space for housing the circuit components and the like is reduced.

An object of the present invention is to provide an electronic device in which the head of the screw used when assembling the housing does not hinder the use and the space inside the housing is efficient.

[0006]

According to the present invention, as shown in FIG. 1, for example, in an electronic device assembled by inserting a screw 30 from the outside of the casing and screwing the screw 30, the screw insertion on the outside of the casing is performed. A raised portion 23 corresponding to the height of the head of the screw 30 inserted into the insertion hole is provided around the hole.

[0007]

By doing so, the raised portion on the surface of the housing covers the head of the screw 30, and only the head of the screw 30 does not project, so that the head of the screw interferes with the use. I won't.

Then, the image light formed on the face plate of the internal image pickup means via the image pickup lens 11 is converted into an electric video signal by each internal circuit, and the video signal obtained by the image pickup is converted by the camera adapter 20. The video signal is transmitted to the signal line 42 through the plug 41 attached to the connector 21, and the video signal is transmitted to the VTR device or the like through the signal line 42. In addition to the main connector 21, a plurality of sub-connectors 22 for connecting various signal lines are attached to the camera adapter 20, as shown in FIG. I / O can be done. FIG. 1 shows a state in which the plug 43 is attached to one of the plurality of sub-connectors 22.

In this case, the camera adapter 20 is separate from the main body of the video camera and can be detached from the main body of the video camera.
Instead of 0, a portable VTR device (not shown) can be attached to form a video device with a built-in camera.

In this example, the camera adapter 2
The case 0 is assembled with the screw 30. That is, the four corners of the surface of the camera adapter 20 on which the main connector 21 and the sub-connector 22 are provided are fixed to the other surface by the screws 30 to be assembled as a housing. Here, in the mounting portion of the lower right screw 30 where the signal line 42 may hit when the plug 41 is mounted to the main connector 21 and the mounting portion of the lower left screw 30 arranged beside the sub connector 22. Is a raised portion 2 on the surface of the housing.
