Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to, for example, CCTV (Cl
The present invention relates to a jig used in the inspection of a TV camera such as an oscillated circuit television.

[0002]

2. Description of the Related Art CCTV cameras are often demanded from the market to be small in size and inexpensive in comparison with television cameras used in studios for broadcasting. When a CCTV camera is sold on the market, the lens has a different standard depending on the field of view of the camera, and therefore, it is customary to sell the lens separately from the camera. In other words, when inspecting a product that has been assembled at the factory, it is usual to inspect the product each time by manually mounting the lens, connecting the connector, etc., and mounting it on the adjustment table. It has been a method.

[0003]

According to the conventional method,
Since the lens mounting, connector connection, and inspection table setting are performed manually, there is a problem in that the cost is high and the quality of the product may be non-uniform due to human variation of the inspector. there were.

In order to solve such a problem, an object of the present invention is to make the quality of products uniform and to make the TV inexpensive.
It is to provide a jig for inspecting a TV camera that can obtain a camera.

[0005]

In order to achieve the above-mentioned object, the present invention provides an angle adjusting base which is supported on a base so as to be adjustable in angle, a lens mounting member fixed on the angle adjusting base, and A camera base that is fixed on an angle adjustment base and guides the camera body so that the lens mounted on the lens mounting member is mounted on the lens mounting portion of the camera body, and the lens mounting portion on the camera mounting base on the camera mounting base. And a connector support base movably provided on the angle adjustment base so that connection means for connecting an electric signal can be attached to and detached from the connector of the camera body set in a state where It is characterized by

[0006]

According to the present invention, the mounting of the lens on the camera body and the connection of the connection means of the electric signal are uniformly performed, and the time therefor is shortened.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, FIG. 2 is a perspective view of an inspection system including this embodiment, FIG. 3 is a plan view of a main portion of this embodiment, and FIG. 4 is a front view of the same. .

1, FIG. 3 and FIG. 4, reference numeral 1 denotes a base, on which a tilt swivel base (having a tilt mechanism and a swivel mechanism as an angle adjusting base, 2 which is adjustable in angle relative to the base 1 in the vertical and horizontal planes. Reference numeral 3 denotes a lens mounting member fixed on the tilt swivel base 2, to which a C mount lens 4 having no thread portion at the mounting portion is mounted. Reference numeral 5 denotes a camera body, which has a lens mounting portion 5A on its front surface and a connector 5B on its rear surface for outputting an image and an auto iris. Reference numeral 6 denotes a camera base fixed on the tilt swivel base 2 and having a pair of parallel guide members 6A provided adjacent to the lens mounting member 3.

Reference numeral 7 denotes a connecting means supporting base, which is movably supported by two guide rails 8 provided on both sides of the camera base 6 on the tilt swivel base 2. A pin 9 for inserting an electric signal by inserting into a connector 5B on the rear surface of the camera body 5 is attached to a mounting member 7A fixed on the support base 7. Further, the support base 7 is mounted on a tilt swivel base. A lock member 10 for fixing to 2 is attached.

The pin 9 is connected to various monitors 11 to 14 and a video analyzer 15 as shown in FIG. 2, which will be described later, via a cable. The lock member 10 is fixed to the handle 10A and a screw member 10B fixed to the base of the handle 10A and attached to the support base 7 so as to vertically penetrate therethrough.
And the screw member 10B tightens the rail 16 on the tilt swivel base 2 by turning the handle 10A or loosens the tightening, thereby fixing the support base 7 to the tilt swivel base 2 or releasing the fixation. To do.

A mounting member 7 on the camera base 6 and the support base 7.
A is the size etc. so that the lens 4 on the lens mounting member 3 can be mounted on the lens mounting portion 5A on the front surface of the camera body 5 to be inspected, and the pin 9 can be inserted into the connector 5B on the rear surface. Has been decided.

With the above arrangement, the camera body 5 is inspected as follows.

First, an operator mounts the camera body 5 on the camera base 6 and presses the front surface of the camera body 5 toward the lens mounting member 3, whereby the lens mounting portion 5A of the camera body 5 is pushed.
The C-mount lens 4 is mounted on, and then the support base 7 is moved to set the pin 9 to the connector 5B on the rear surface of the camera body 5.
To insert. As a result, the lens mounting and the connection for extracting the electric signal are uniformly performed with respect to the camera body 5. The time required for this is much shorter than in the past.

Then, the power of the camera body 5 is turned on, and as shown in FIG. 2, the inspection pattern 17 at a predetermined distance from the base 1 is imaged by the camera body 5, and the image is displayed on the measurement point confirmation monitor 11. indicate. When the inspection pattern deviates from the predetermined position on the monitor 11, the deviation is corrected by the tilt swivel base 2, and then the predetermined inspection is performed using the video analyzer 15. The computer 18 can manage and store the obtained inspection data, for example. Reference numeral 12 is a visual confirmation monitor, 13 is a data output monitor, and 14 is an iris operation confirmation monitor.

The inspection items by the video analyzer are, for example, SYNC level, PED level, VIDEO.
Level, gamma characteristic, shading, AESC operation, etc. During these inspections, the inspector looks at each monitor screen and sees image quality items such as resolution, CCD scratches and dust, noise, modulation degree, F (frequency). ) It is possible to judge the quality of the characteristics and the iris operation.

[0017]

As described above, according to the present invention, T
When inspecting V-cameras, variations due to artificial skill differences are eliminated. In addition, the inspection time is only about 50% of the conventional one, and the cost can be reduced.
