摘要： PROBLEM TO BE SOLVED: To enhance the reliability of the optical transmitter-receiver by covering a transmission reception unit with a dome shaped light shield cover so as to effectively interrupt other lights than a communication light thereby avoiding a light reflected in the light shield cover from reaching a receiver side lens and eliminating external disturbance of the signal light. SOLUTION: Part of light passing through a transmission lens 12 may be inverted (reflected) by the inner face of a light shield cover 3 as shown in the arrow 4 and go to a light receiving element 14, then the light shown in the arrow 4 is shut by a barrier 66. Furthermore, the light passing through a point apart from a center of the transmission lens 12 goes as shown in the arrow 5 due to distortion, may be reflected in the inner face and go to the light receiving element 14, then the light shown in the arrow 5 is shut by the barrier 66. Moreover, the barrier 66 plays a roll of attenuating external disturbance light by reflecting the light in a wall face of an integrated visor 65 including the barrier 66 repetitively.

摘要： PROBLEM TO BE SOLVED: To lighten in weight and miniaturize a device and to improve tracking speed by cantilever-supporting a first axis rotation mechanism held by a first supporting member so that it rotates a light transmission/reception unit around a first axis and the optical transmission/reception unit by means of a second supporting member so that they rotate around a second axis orthogonal to the first axis and rotating them by means of a second rotation mechanism. SOLUTION: An optical transmission/reception unit 10 emits the transmission light of light emitting element through a transmission lens 12 and received light collected through a reception lens 13 by a light-receiving element. A first axis rotation mechanism 30 is supported by the first feed forked first supporting member 20 so that it can be rotated with the first axes 15 and 15 supporting the optical transmission/reception unit 10. A second axis rotation mechanism 50 is fitted to a second supporting member 40 so that it cantilever-supports a first supporting member 20 through a second axis 24 orthogonal to the first axis 15 and it rotates the second axis 24. The optical transmission/reception unit 10 can be rotated with the first axes 15 and 15 as centers or the second axis 24 as a center and tracking can satisfactorily be executed.

摘要： PROBLEM TO BE SOLVED: To attain the miniaturization and light weighting as well as increasing the follow-up rate by a method wherein the distance from the first axis to the top of a transmitting side lens is set up to be shorter than that of a receiving side lens. SOLUTION: Within a comparison embodiment (a) wherein the top of a transmitting side lens 120 is equalized with the top of a receiving side lens 130, the diameter of a virtual circle encircling a block 160 is assumed to be D1. When another transmitting side lens 12 is lowered by h from another receiving side lens 13 so as to set up the distance from the first axis 15 to be shorter than that of the receiving side lens 13 (b), the diameter D2 of the virtual circle encircling another block 16 can be made shorter than the D1. Resultantly, a light transmitting unit 10 can be made compact so as to reduce the torque required for turning around the first axis thereby enabling the load of the first motor to be reduced.

摘要： PURPOSE:To provide the color image display device which is simple in constitution and is good in superposition. CONSTITUTION:Writing of image information is executed by imaging the luminous flux optically deflected by one oscillating mirror Mg1 of two oscillating mirrors Mg1, Mg2 mounted apart a prescribed spacing at a driving shaft 3 oscillated and driven by one driving section 4 on a photoconductive member of a spatial optical modulation element SLM1 of an optical writing type by imaging lens L1, L2. The luminous fluxes modulated in intensity by the time-division signals of the time base compression signals of the image signal of a red original image and a blue original image to deflection with the oscillating reflection mirror Mg2 are imaged on the photoconductive layer member of the spatial optical modulation element SLM2 of the optical writing type by imaging lenses L3, L4, by which the writing of the image information is executed. The reading out light of the wavelength region corresponding to the respective specific original colors generated by decomposing the light radiated from a light source LS for reading out light is applied to the spatial optical modulation elements SLM1, SLM2 of the optical writing type, by which the reading out of the image information is executed. The light modulated by respective the image information read out respectively discretely is projected by a common projecting lens Lp to a screen S.

摘要： PURPOSE:To set optimization state of a write optical system by roughly adjusting the positions of an array and an optical system so as to make the light of a light emitting element reach the center of a reference image. CONSTITUTION:A galvanomirror GM and lenses L1 and L2 can perform each necessary one of those actions including the displacements carried out in the directions of three axes X, Y and Z and the rotations carried out around these axes as an adjustment drive action. This drive action is automatically or manually carried out by the control signal which is supplied to an adjustment drive mechanism from a control part 6 of a control device CTA. The placement mode of each optical member of the component elements of a write optical system is calculated based on the parameter of the optical member and then repetitively changed by the adjustment drive mechanism of each optical member. Thus the optimization state is secured for the write optical system.

摘要： PURPOSE:To prevent the invasion of dust in a fine interval by providing a fan-shaped air bearing plate which has a surface to show satisfactory flatness on a substrate and providing the thin liner of unwoven fabric in the other part of the substrate. CONSTITUTION:In the part of a liner 12 provided in the part excepting for a fan-shaped air bearing plate 11 in a substrate 9, a thin layer air current flowing from the inner circumference of a flexible recording medium disk 17 to an outer circumference flows to the interval of fiber (f) which constitutes the liner 12. Thus, the dust included in the air is removed by the fiber (f) which constitutes the liner 12. The upper part of the fiber (f) contacts the surface of the disk 17 and removes the dust which is attached on the disk 17 and an electrostatic charge is not charged in the disk 17. Thus, even when the disk 17 is rotated at a high speed, charging is generated in the disk 17 and electrostatic attraction is not generated in the interval with the plate 11.
