There is. The phosphorescent spots are deposited, for example, by photochemical treatment, and the position of the phosphorescent spots on the screen plate is precisely formed with respect to the axis of the electron gun corresponding to each phosphorescent spot. The arrival point of the electron beam on the screen plate must exactly match the position of the phosphorescent spot corresponding to each electron beam.

によって整合可能となる。German Patent Application No. 2 354 338 discloses a method, according to which the electron gun unit has a reference that includes the center points of at least two passage holes for the electron beam provided in an acceleration and focusing grid. The direction is used for alignment. This groove is composed of two groove-shaped parts with their bottoms facing each other. The bottoms of these are provided with electron beam passage holes. Grid gear used in in-line picture tubes,! The fall portion has, for example, a flat side surface extending parallel to a plane containing the central axis of the electron gun. The two mechanical measuring rods formed by displaceable apertures are arranged in the above-mentioned apertures when the electron gun unit and picture tube are arranged separately from each other in a sealed structure of glass and metal. , is adapted to make contact with one of the flat sides of the do. These measuring rods measure the distance between the reference plane representing the ideal position of the electron gun unit relative to the screen plate and the contact point of the measuring rod between the grid flat gaps. Alignment is made possible by rotating the electron gun unit about its central longitudinal axis to equalize the two measured travel distances while monitoring the comparator.

によっては電子銃ユ°二、トを傷つけることさえある。In order to perform accurate measurements, the two measuring rods must be spaced apart from each other as much as possible in the lateral direction.The space and the electron gun unit may deviate parallel to each other during assembly. So one of the measuring sticks is Guri, P
It is easy for the electron beam to come into contact with the edge portion of the flat side surface of the electron gun and even to cross over the flat side surface of the electron gun.
