Apparatus for photolithographic exposure of cathode ray tube

An apparatus for exposing an inner surface of a color cathode ray tube during manufacturing of the cathode ray tube, the apparatus comprising:

• a light source for exposing an inner surface of a color cathode ray tube;
• continuous light-emitting circuit means electrically connected to said light source for causing said light source to emit light continuously;
• a slit arranged close to said light source for adjusting the size of an exposure pattern produced by said light source;
• supporting means for supporting and fixedly holding said light source;
• moving means coupled to said supporting means for moving said supporting means in first and second orthogonal directions, said moving means comprising a cam assembly including a first cam coupled to said supporting means for moving said supporting means in the first direction, a cam supporting member supporting said first cam, and a second cam coupled to said cam supporting member for moving said supporting means in the second direction.
