<p>PURPOSE:To accomplish high speed switching and irradiation of light having different wavelength and to perform high speed multicolor recording in which the high speed switching and irradiation of the light is used with simple structure by providing a rotor having plural phosphors, a mounting member, a supporting member, a light source and a driving means. CONSTITUTION:Three kinds of phosphors A-C are applied to the inner surface of the rotor 3a consisting of a glass cylinder in stripes of 120 deg.. The mounting members 3b are mounted on both ends of the rotor 3a through tapered parts and the outer peripheral parts of the members 3b are attached to the supporting members(housing) 3d through ball bearings 3c. The light source 3g is disposed in the rotor 3a and the respective phosphors A-C are allowed to emit the light by turning on the light source 3g. When a light source motor 3f is driven and the light source 3g emits the light, the phosphors A-C are excited to emit the light and three kinds of light respectively having different peak wavelengths pass through a slit 3h and are alternately switched to irradiate an object to be irradiated. The control of a rotating speed and a phase is performed with the signal of a rotation detecting sensor 3j. Therefore, the high speed multicolor recording is performed by arranging a recording device whose structure is simple on a slit side.</p> |
