Abstract

PURPOSE:To measure promptly and accurately an inserting inclination of an electron gun by rotatably attaching on a stem pin guide a measuring instrument for an eccentric degree of the outer wall of the neck tube of a picture tube. CONSTITUTION:When a rotary lever 11 is turned, a measuring instrument 12 is also turned about a stem-pin guide 10, namely, using the stem-pin 7 as its reference. Thus, the eccentric degree of the outer wall of the neck tube of a picture tube is measured relative to the pin 7 so that the eccentric valve is indicated on a digital indicator 15 through an eccentric valve calculator 14. Thereby, the inserting inclination of an electron gun can be measured promptly and accurately.
