Abstract

PURPOSE:To detect accurately the rotational position of an electron gun structure without any modification by a method in which a flat electrode used in the electron gun structure, is irradiated with a light beam, the reflected light is received by a light detector, and the relative rotational position of the structure and bulb is determined. CONSTITUTION:A light source 24, half-mirror 25, slit 26, and light detector 27 are provided in a prescribed position of the device, while those units are provided for rotationally locating at a prescribed position an electron gun structure 1 mounted on a mount pin, and when a flat plane of an outside electrode plate 2a of a convergence means 2 of the structure 1 is arranged so as to face the light source 24, a light beam transmitted through the mirror 25 is radiated perpendicularly on the electrode plate 2a, a reflected light which is deflected at the mirror 25 by a right angle is introduced into the light detector 27 through the slit 26 when the outside electrode plate 2a coincides with a rotational prescribed position. Thus the rotation of an electron gun structure is detected easily and accurately.
