  • Patent number: 4206986
    Abstract: In an exposure apparatus used for manufacture of color cathode-ray tube phosphor screen, a coupling section of an exposure light source to be coupled with a light source receiving portion of a light source housing has a function to previously align a predetermined portion of a light emitting section of the light source positionally in relation to the light source receiving portion. The coupling section of the light source may include an adjustment mechanism which is operatively connected with the light emitting section so as to move it or a member which is rigidly secured to the light emitting section and a predetermined portion of which is aligned with the predetermined portion of the light emitting section. The light source having the adjustment mechanism may be coupled with the light source housing of the exposure apparatus after a desired adjustment has been effected.
