Abstract

PURPOSE:To easily perform the positional alignment of a video camera. CONSTITUTION:A video camera 25 is formed with projection parts 35 and 36 on both sides of the front face of a U-shaped part 31. The tips of these projection parts 35 and 36 indicate the end and position of a camera optical part 28 and used as a mark for the positional alignment in integrating a camera fitting 24 and the video camera 25. At the time of mounting the camera fitting 24 on an upper case 22, the video camera 25 slides forward or backward with respect to the camera fitting 24 based on the projection parts 35 and 36 of the camera fitting 24 to perform the positional alignment of a video camera 27, and then the camera fitting 24 is mounted on either the upper case 22 or a lower case 23. Thus, the positional alignment of the video camera 25 can be performed easily.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera device such as a security camera in which a video camera is housed in a case, and more particularly, a video camera which facilitates positioning of the video camera in the case Regarding the device.

[0002]

2. Description of the Related Art In recent years, stationary video camera devices such as security cameras have become popular not only in financial institutions but also in general small stores. In such a stationary video camera device, the video camera is housed in a case in order to protect the video camera from dust and dirt in the atmosphere.

FIGS. 10 and 11 show such a conventional video camera device, FIG. 10 is a perspective view, and FIG. 11 is a sectional view.

In FIG. 10, reference numeral 1 is a rectangular cylindrical case. The case 1 is provided with a transparent plate 2 such as a windshield on the front surface thereof, and a video camera 3 is housed inside.

As shown in FIG. 11, the case 1 includes an upper case 1a formed by bending a metal plate in a U shape when viewed from the front and a lower side formed by bending the metal plate in a U shape when viewed from the side. It is composed of a case 1b. Lower case 1
A camera attachment 4 is attached to the inside of b, and a video camera 3 is attached to the camera attachment 4 with a camera screw 5.

The video camera 3 includes a video camera controller 6
And the camera optical unit 7. The video camera control unit 6 has a camera unit and a signal processing unit (not shown) inside. The video camera control unit 6 includes a camera optical unit 7 on its front surface, and a power cord 8 and an imaging cable 9 from the rear surface side.
Has been derived. The power cord 8 and the imaging cable 9 extend to the outside of the case 1 via bushings 10 and 11, respectively.

FIG. 12 is a bottom view of the video camera 3 with the camera fixture 4 attached.

In FIG. 12, the camera mount 4 includes
Two slits 12, 12 are formed in the front-rear direction. The camera screws 5 and 5 are inserted into the two slits 12 and 12, and are screwed into the screw holes formed in the video camera control unit 6 so that the video camera 3 can be attached to the camera attachment 4. There is.

In such a conventional video camera device, in order to secure the field of view of the video camera 3, the camera optical section 7 must be disposed close to the light transmitting plate 2. In general, the size of the optical system and the like of the video camera differs depending on the type. Therefore, when assembling the video camera device of FIG. 11, the upper case 1a is removed and the two camera screws 5 and 5 are attached. The video camera 3 is attached to the camera fixture 4 by inserting it into the rear of the slits 12 and 12 and screwing it into the screw hole formed in the video camera control unit 6 while being loosened to some extent. Attach to the lower case 1b. After that, the video camera 7 is slid with respect to the camera attachment 4, and the camera optical unit 7 is slid to the position immediately before the translucent plate 2. In this state, the camera screws 5 and 5 are completely tightened to fix the video camera 3 to the camera mount 4. This prevents the camera optical unit 7 from hitting the transparent plate 2 and damaging the transparent plate 2.

However, in such a video camera device, when the device is assembled or the video camera is replaced, the translucent plate 2 is attached with the video camera 3 attached to the lower case 1b via the camera attachment 4. Since the position adjustment is performed by sliding the video camera 3 on the basis of, the workability is very poor. This poor workability is especially
This has been a problem when performing maintenance and inspection while the lower case 1b is installed on an installation member such as a pole. This also applies to a video camera device in which the video camera is directly attached to the camera case.

[0011]

In the above-mentioned conventional video camera device, the size of the video camera varies depending on the type. Therefore, with the video camera mounted in the case, the video camera of the video camera can be used as a reference with the translucent plate. The workability was very poor because the slide had to be adjusted for alignment.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a video camera device which can eliminate the above-mentioned problems and can adjust the alignment of the video camera by a simple method.

[0013]

According to the present invention, there is provided a video camera including an upper case, a lower case assembled with the upper case, an optical section and a control section, and a state in which the video camera can be slid back and forth. And a camera mount that is attached to one of the upper case and the lower case and that has a protrusion that indicates the tip position of the optical part of the video camera on the front surface. A transparent plate attached to the front surface of one of the inner sides and guiding external light to the optical part of the video camera.

[0014]

According to this structure, the video camera is slid back and forth with respect to the camera mount with respect to the protrusion of the camera mount to adjust the position of the video camera, and then the camera mount is adjusted. Since the can be attached to one of the upper case and the lower case, the position adjustment of the video camera can be easily performed.
