Abstract: PURPOSE:To lighten a color image by mixing a beam of 568.2nm and a beam of 647.1nm emitted from Kr laser or Ar-Kr mixed gas laser and using the resulting laser light as the red light of an image. CONSTITUTION:A beam of 568.2nm (yellow light) and a beam of 647.1nm (red light) emitted from Kr laser or Ar-Kr mixed gas laser are mixed to obtain laser light corresponding to single-color light of about 612nm. When this laser light is used as the red light of an image, lightness is increased by laser light of 568.2nm as compared with the conventional case using only red laser light of 647.1nm and the lightness of the entire image is increased. The consumption of electric power is reduced if it is not necessary to increase the lightness of the entire image. A laser image display is reduced in size as compared with a display using dye laser.

Abstract: PURPOSE:To optically eliminate the unequal pitches of horizontal scanning lines and to obtain high image quality by paralleling the incident laser beam and reflected laser beam of a rotary polyhedral mirror. CONSTITUTION:The laser beam is repeatedly reflected by the rotary polyhedral mirror 8 and reflecting means 20a, 20b to expand the deflection angle of the laser beam by the mirror 8. The reflecting means 20a, 20b are formed to have at least a part of the reflecting surfaces intersecting orthogonally with each other to parallel the laser beam li made incident to the mirror 8 and the laser beam lo emitted therefrom with each other when viewed from the plane perpendicular to the plane inclusive of the radius around the axial center of the mirror 8. As a result, the unequal pitches of the horizontal scanning lines are optically removed and the need for the costly rotary polyhedral mirror which is extremely little in the axis misalignment is eliminated.

Abstract: PROBLEM TO BE SOLVED: To perform recording of information with high density to an optical disk and to perform stable tracking control. SOLUTION: A guide track Tg having a track interval twice as wide as a track interval Pr of a recording track Tr is provided on a reflection layer transmitting an information light beam Lb1 and reflecting a position controlling light beam Lr1 having a wavelength longer than that of the information light beam Lb1. Thereby, tracking control can be reliably performed by using the position controlling light beam Lr1 having the wavelength longer than that of the information light beam Lb1 while the recording track Tr is set in an interval according to a spot diameter of the information light beam Lb1 to enhance recording density.

Abstract: PROBLEM TO BE SOLVED: To precisely record or reproduce a hologram showing information on an optical disk. SOLUTION: When recording information on an optical disk 100, this disk drive makes the focusing point Fr follow the desired track by controlling the position of the objective lens OL1 based on the result of detecting the reflected red light beam Lr2, and moves the focusing point Fb1 of the blue light beam Lb1 to the desired mark position by the objective lens OL1. Further, it moves the focusing point Fb2 to the desired mark position by controlling the objective lens OL2 based on the result of detecting the blue light beam Lb1 through the objective lenses OL1 and OL2. Since the focusing point Fb1 of the blue light beam Lb1 and the focusing point Fb2 of the blue light beam Lb2 can be moved to the same mark position to interfere with each other, it can record the recording mark RM on the desired mark position.

Abstract: PROBLEM TO BE SOLVED: To provide a sheetlike information display/recording medium which can be mass-produced at a low price and manufactured from a material which does not cause an environmental problem even when the medium is disposed of and an information reading device which reads the recorded contents of the sheetlike information display/recording medium. SOLUTION: A postcard for notice 1A as the sheetlike information/recording medium comprises a visually recognizable information display part 10A in which visually recognizable information is loaded and an information recording part 11A from which recorded data can be optically read. The information recording part 11A whose recorded data is optically readable codes information relative to the contents loaded in the part 10A and adds an error correction code, if necessary, to cipher the information. Thus the information converted into symbolic codes such as bar code and Calra code is printed after ciphering. The symbols printed in the information recording part 11A can be visually recognized but their contents cannot be deciphered by means of a bar code reader of the POS terminal because the symbols are coded and ciphered. A flatbed scanner or the like is used for deciphering the contents.

Abstract: PROBLEM TO BE SOLVED: To enhance luminescent brightness. SOLUTION: A dielectric film 3 for reflecting an ultraviolet light and transmitting a visible light, an ultraviolet light emitting electroluminescent element 10 for radiating the ultraviolet light and a wavelength conversion film 9 for wavelength-converting the ultraviolet light and radiating the visible light in the incident direction of the ultraviolet light are stacked in this order and formed on a transparent substrate 2. Thereby, the ultraviolet light radiated from the ultraviolet light emitting electroluminescent element 10 to the dielectric film 3 side is reflected from the dielectric film 3 and enters the wavelength conversion film 9.
