Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image pickup tube mounting device, and is designed to easily adjust the mounting position of the image pickup tube.

The following will be explained with reference to an embodiment of the drawings. 1 is an image pickup tube; 2
For example, the camera base has a bent portion 3 at one end, a screw hole 6 to which a camera lens 4 and a flange adjustment ring 5 correspond.

I is a coil assembly, 8 is an engaging part 10 that engages with the recess 9 of the coil assembly 7, and a horizontal view angle adjustment ring having a long hole 11 on the outer periphery, 12 is a ring for fixing the horizontal adjustment ring, and 13 is a flange adjustment ring. A spring 14 is a screw for fixing the horizontal angle of view and a flange back guide, and 15 is a coil assembly support stand which is fixed to the camera base 2 with screws 16.

17 is a long hole.

Next, the assembly order of this device will be explained.

1. Insert the image pickup tube 1 into the coil assembly T, fix it with a clamp screw (not shown), and then screw it into the screw hole 6 in advance.
One end of the coil assembly 1 is joined to the flange adjustment ring 5 adapted to the above, and then the spring 13 and the fixing IJ ring 12 are connected to the other end of the coil assembly T through the elongated hole 11 of the ring 8 and the elongated hole 11 of the support base 15. The recess 9 of the coil assembly 7 and the engagement part of the ring 8 are matched to the support base 15 which has been temporarily attached through the screws 16, and the support base 15 is fixed to the camera base 2 with screws 16.

(This step may be performed using another method.

) Next, take out the output from the image pickup tube 1 and adjust the horizontal angle by rotating the coil assembly 1 while looking at the monitor screen (at this time, the ring 8 follows the coil I, but the fixed ring 12 has a long hole). It is fixed with screws 16 via 7.

) The ring 8 and the fixing ring 12 are locked by locking the screw 14 temporarily fastened to the ring 12 through the elongated hole 17.11.
The horizontal angle of view of the coil assembly 1 is fixed due to the relationship between the elongated hole 17 and the screw 14.

After that, by fine-tuning the guide 5 by 1,
Since the screw 14 moves using the 1T long hole as a guide, it is possible to prevent the coil assembly 7 from becoming stuck.

The present invention has been described above, and with this configuration, the screw 14 or a substitute thereof fixes the horizontal angle of view of the coil assembly T and the image pickup tube 1, while
Since it serves as a guide for 7-flange adjustment, there is no need to separately provide a guide means for anchoring in conjunction with flange adjustment, and various purposes can be achieved with a simple configuration.
