Abstract
An inspection method and an inspection apparatus for the component members of the cathode-ray tube are disclosed. An inspection apparatus composed of normal members other than an object of inspection is prepared at the time of inspecting the phosphor screen of the screen panel, the electron gun or the shadow-mask constituting the cathode-ray tube. In advanced to assembling the cathode-ray tube, the object of inspection is mounted on the inspection apparatus, so that the conformance or rejection of the object of inspection is decided from the illuminated condition of the phosphor screen by irradiating electron beams thereon.
