Integrated pickup component and adjusting arrangement therefor

Abstract

An integrated pickup component used to support and mount thereto image pickup tubes is mounted to a color separation optical system of a multi-tube type color television camera. The integrated pickup component comprises a plurality of primary assembly retaining cylinders each housing an image pickup tube and its peripheral parts which are to be fixed to the cylinder with an adhesive in a ready-to-use manner, and a mount holder integrally formed in itself for attaching thereto the primary assembly retaining cylinders of respective image pickup tubes. Before connecting and fixing this integrated pickup component to the color separation optical system of the color television camera, the component is attached to an adjusting arrangement having an optical system with identical functions to those of the color separation optical system for the camera. The relative positions between each of the primary assembly retaining cylinders and the mount holder are adjusted by monitoring with a picture monitor the correct registration of the color separated optical images with the electron beam scanning areas in respect of their focus points, the sizes, the rotational positions and the center positions through the use of the optical system of the adjusting arrangement. Relative positions thus adjusted are then fixed with an adhesive.
