Claims
- 1. A coloring device comprising:
- a filter assembly including color filter sections of at least three colors; and
- a driving unit for rotating said filter assembly such that said color filter sections pass a predetermined position as said filter assembly is rotated;
- wherein
- said driving unit includes a rotary motor further including a stator and a rotor for rotating said filter assembly; and
- said filter assembly is directly mounted to said rotor of said motor and wherein neither said filter assembly nor said rotor of said motor includes an output shaft.
- 2. The color device according to claim 1,
- wherein said filter assembly further includes a rotary filter having said color filter sections, and a connection member fixed to said rotary filter and fixed to said rotor of said motor.
- 3. The coloring device according to claim 2, wherein
- said rotary filter has a truncated cone shape with a smaller-diameter end; and
- said connection member is fixed to the smaller-diameter end.
- 4. The coloring device according to claim 3, wherein
- said stator and said rotor have a disk-shape and stator and said rotor have first surfaces confronting each other; and
- said connection member fixes said rotary filter to said rotor.
- 5. The coloring device according to claim 4, wherein
- said connection member has a first surface to which the smaller-diameter end of said rotary filter is connected and a second surface in contact with a second surface of said disk-shaped rotor.
- 6. A color image display system comprising:
- a monochromatic image display device including a screen for displaying images;
- a filter assembly including color filter sections of at least three colors;
- a rotary driving unit for rotating said filter assembly such that said color filter sections pass over said screen as said filter assembly is rotated; and
- a signal supplying device for supplying said monochromatic display device with color image signals of the at least three colors in a predefined sequence;
- wherein said rotary driving unit including a rotary motor further including a stator and a rotor for rotating said filter assembly;
- wherein said filter assembly is directly mounted to said rotor of said motor and wherein neither said filter assembly nor said rotor of said motor includes an output shaft.
- 7. The color image display system according to claim 6,
- wherein said filter assembly further includes a rotary filter having said color filter sections, and a connection member fixed to said rotary filter and fixed to said rotor of said motor.
- 8. The color image display system according to claim 7, wherein
- said rotary filter has a truncated cone shape with a smaller-diameter end; and
- said connection member is fixed to the smaller-diameter end.
- 9. The color image display system according to claim 8, wherein
- said stator and said rotor have a disk-shape and said stator and said rotor have first surfaces confronting each other; and
- said connection member fixes said rotary filter to said rotor.
- 10. The color image display system according to claim 9, wherein
- said connection member has a first surface to which the smaller-diameter end of said rotary filter is connected and a second surface in contact with a second surface of said disk-shaped rotor.
- 11. A rotary filter of a coloring device comprising:
- color filter sections of at least three colors;
- wherein
- said rotary filter has a truncated cone shape; and
- each of said color filter sections is formed of a transparent base provided with one of a filter sheet attached to each of said color filter sections and a coating having a transparency only to light of one of the at least three colors.
