Abstract
A color-selecting apparatus of a color display device which can effectively suppress vibration generated in a color-selecting electrode system, wherein one side of a supporting plate spring is fixed to a frame via a holder, and the other side of the supporting plate spring is fixed to the frame. The supporting plate spring is constituted by laminating flat plate springs, and the flat plate springs relatively move by deformation accompanying the vibration from the outside. The vibrational energy is consumed by the frictional energy generated between them.
Claims12
A cathode ray tube comprising:
- a fluorescent glass panel;
- a plurality of pins provided on a surface of said fluorescent glass panel;
- a frame member;
- a color selection electrode system supported by said frame member;
- and
- a plurality of supporting members, each supporting member having a first end fixed to a portion of said frame member and a second end fixed by a first of said plurality of pins to support said frame member and said color selection electrode system to said surface of said fluorescent glass panel,
- each of said plurality of supporting members comprising a first plate spring member and a second plate spring member having an outer shape substantially equal to an outer shape of said first plate spring member, said first plate spring member and said second plate spring member having predetermined spring characteristics for supporting said color selection electrode system to said surface of said fluorescent glass panel at a predetermined spring force,
- said first plate spring member having a first opening into which said first pin is fittingly inserted,
- said second plate spring member having a second opening larger than said first opening, into which said first pin is inserted,
- said first end of each supporting member comprising first ends of both said first and second plate spring members, said first pin fittingly inserted into said first opening of said first spring member and inserted into said second opening of said second spring member at second ends of both said first and second plate spring members.
A color selecting apparatus for a cathode ray tube including a fluorescent glass panel having a plurality of pins, comprising:
- a frame member;
- a color section electrode system supported by said frame member;
- and
- a plurality of supporting members, each supporting member having a first end fixed to a portion of said frame member and a second end fixed by a first of said plurality of pins to support said frame member and said color selection electrode system to said surface of said fluorescent glass panel,
- each of said plurality of supporting members comprising a first plate spring member and a second plate spring member having an outer shape substantially equal to an outer shape of said first plate spring member, said first plate spring member and said second plate spring member having predetermined spring characteristics for supporting said color selection electrode system to said surface of said fluorescent glass panel at a predetermined spring force,
- said first plate spring member having a first opening into which said first pin is fittingly inserted,
- said second plate spring member having a second opening larger than said first opening, into which said first pin is inserted,
- said first end of each supporting member comprising first ends of both said first and second plate spring members, said first pin fittingly inserted into said first opening of said first spring member and inserted into said second opening of said second spring member at second ends of both said first and second plate spring members.
