Field of Industrial Application) The present invention relates to a novel video camera. Specifically, by devising mounting holes for attaching components that are necessary for this type of camera to the housing, the position supported by the camera support means can be adjusted to the housing without increasing the number of components at all. It is an object of the present invention to provide a novel video camera which allows selection between a position on one of the outer walls of the present invention and a position on another outer wall.

(B. Summary of the Invention) The video camera of the present invention has a mounting hole for mounting an output terminal and a mounting hole for mounting a connecting member connected to the camera support means, which are formed separately in two outer walls of the casing. The shapes of the mounting holes are made the same, so that the positions of the output terminal and the connecting member can be exchanged between them, so that the positions supported by the camera support means can be changed without increasing the number of parts at all. can be selected between a position on the negative outer wall of the casing and a position on another outer wall.

(C. Background Art) Today, video cameras are used in various places and for various purposes.

By the way, when it is necessary to stably support a video camera or fix its position, the video camera is supported by an appropriate camera support means, especially when used as a surveillance camera for a specific location. Usually, the video camera is supported by camera support means fixed to a wall or ceiling.

Therefore, video cameras are usually provided with a coupling part for coupling with camera support means.

However, depending on the shooting direction, even if you try to support the video camera on the camera support means in an attitude that corresponds to the shooting direction, it may not be possible to support it, or it may not be possible to support it. However, it can also become extremely unstable.

Therefore, a plurality of connection parts for connection with the camera support means are provided separately on the plurality of outer walls of the casing, and the position supported by the camera support means is set among the plurality of connection parts according to the desired posture. It is possible to make it possible to select from.

However, if a plurality of connecting parts are provided, the number of parts of the video camera increases, which increases the cost and weight, and also causes various problems such as poor appearance.

The power terminal and the connecting member can be exchanged in position therebetween.

Therefore, in the video camera of the present invention, the connecting member can be selectively attached to either one of the two mounting holes, and the output terminal can be attached to the remaining one of the two mounting holes. Even if the number of holes, output terminals, and connecting members are not increased at all, the position supported by the camera support means is selected between a position on the negative outer wall of the casing and a position on the other outer wall. be able to.

In the following description, the bottom plate 4 of the chassis 3 will be referred to as a "bottom wall," and the back plate 5 will be referred to as a "rear wall."

(b, mounting hole) [Fig. 1, Fig. 2, Fig. 5] 24 and 2
5 is a mounting hole formed separately in the bottom wall 4 and the rear wall 5;
That is, the connecting member and the output terminal described later are each separately, and
This is a mounting hole for selectively mounting between these connecting members and the output terminal.

These mounting holes 24 and 25 have an abbreviated shape that is the same shape as the horizontal cross-sectional shape of a portion of the connecting member and output terminal that will be described later, which are inserted through these mounting holes 24 and 25, respectively.
That is, although it is basically circular, parts 24a and 25a of the circular outer periphery extend linearly, and both are formed to have the same size.

That is, these two mounting holes 24 and 25 are formed to have the same shape and size.

One of these two mounting holes 24 and 25 24 (
Hereinafter, it will be referred to as the "first mounting hole." ) is formed at a position near the center of the bottom wall 4 and slightly forward (this position is close to the center of gravity of the video camera 1).

Note that the output terminal 31 is rotated by having the flat portion 32a of the outer circumferential surface of the helical shaft portion 32 facing in parallel with the linearly extending portion 25a or 24a of the mounting hole 25 or 24. The nut 39 can be easily screwed together and can also be prevented from loosening.

Therefore, when the output terminal 31 is attached to the second mounting hole 25 (FIGS. 1, 3, and 4 are shown in this state), the pin jack portion 33 is pushed backward from the back wall 5. In addition, when the output terminal 31 is attached to the first mounting hole 24 (FIGS. 5 to 7 are shown in this state), the pin jack portion 33 is positioned so as to protrude from the bottom wall 4. It is positioned so as to protrude downward.

(Effects of the G0 Invention) As is clear from the above description, the video camera of the present invention includes a photographic lens provided on the front wall of the housing, and an image sensor disposed behind the photographic lens. A mounting hole for mounting an output terminal for outputting the video signal captured by the camera to the outside, and a mounting hole for mounting a connecting member connected to the camera support means are formed on each separate outer wall part of the housing other than the front wall. The video camera is characterized in that the two mounting holes have the same shape, and the positions of the output terminal and the connecting member can be exchanged between them.

Therefore, in the video camera of the present invention, the connecting member can be selectively attached to either one of the two mounting holes, and the output terminal can be attached to the remaining one of the two mounting holes. Even without increasing the number of mounting holes, output terminals, and connecting members at all, it is possible to change the position supported by the camera support means between the position on the negative outer wall of the casing and the position on the other outer wall. You can choose.

In the above embodiment, the shape of the mounting hole was made into an abbreviated shape so as to have a rotation prevention function for the output terminal and the connecting member inserted therein. The shape of the hole is not limited to such a shape, and may be any shape that corresponds to the cross-sectional shape of the attachment hole insertion portion of the output terminal and the connecting member.

In addition, in the embodiment, two mounting holes are provided separately on the bottom wall and rear wall of the casing, but if the outer wall portions where these mounting holes are provided are also on separate outer wall portions of the casing, It can be selected arbitrarily depending on the center of gravity position of the video camera and the arrangement of each member, and furthermore, in addition to the output terminal and connecting member, it can be attached to the casing through the mounting hole formed in the outer wall of the case. If the mounting hole for attaching the other member can be made the same shape as the mounting hole for attaching the connecting member and the mounting hole for attaching the output terminal, then It is also conceivable that the positions of the member, the connecting member, and the output terminal can be exchanged between these members.

It goes without saying that the technical scope of the present invention should not be interpreted as being limited by the functions of the video camera or the structure of the output terminal, connecting member, camera support means, etc. shown in the embodiments.
