<p>A picture apparatus includes a vacuum envelope (30) which has a phosphor screen (5) and a plurality of electron gun assemblies (7) for emitting electron beams to the phosphor screen, and a deflection device (12) for deflecting the electron beams emitted from the electron gun assemblies. The deflection device has a plate-like coupling member (11) arranged to face the vacuum envelope, and a plurality of elemental deflection units (10) for deflecting the electron beams to scan the phosphor screen dividedly. The deflection units are fixed to the coupling member and located at positions, respectively.</p> |
