摘要： A key switch of a keyboard of the present invention includes a key cap and an elastic body which supports and allows the key cap to elastically move up and down. The elastic body is a band shaped structure and includes end portions which are pivotally supported above a substrate, a central portion bulged to contact a bottom surface of the key cap, and curved portions having a curvature opposite to that of the central portion disposed between corresponding ones of the end portions and the central portion. The curved portions of the elastic body are deformed at a position lower than an upper surface of the substrate. Therefore, the overall height of the key switch can be reduced, allowing for the manufacture of a slimmer keyboard unit.

摘要： A color laser printer producing a color image using a single laser scanning unit includes a lighting unit including first and second laser diodes emitting beams of one polarization, a polarization prism transmitting or reflecting incident beams depending on a direction of polarization, and third and fourth laser diodes disposed in a different direction from the first and second laser diodes with respect to the polarization prism, a rotary polygon mirror that reflects the beam emitted along the same path from the lighting unit, an f-θ lens that focuses the beam reflected by the rotary polygon mirror, first and second polarization beam splitters, each of which transmits or reflects the beam passing through the f-θ lens depending on the direction of the polarization, and first through fourth photoconductive units on which the beams reflected and transmitted through the first and second polarization beam splitters are incident. In the color laser printer, lengths of optical paths between the f-θ lens and each of the first through fourth photoconductive units are equal. The color laser printer is constructed such that a plurality of light sources emitting the beams of one polarization are arranged separately and the beams emitted from the light sources are combined by the polarization prism to enter the f-θ lens, thereby reducing a thickness of the f-θ lens.

摘要： An optical pickup device includes a light unit for irradiating a light beam having a wavelength longer than 650 nm onto a recording medium and receiving and detecting a light beam reflected by the recording medium, and an objective tens formed of a single lens having an NA of 0.7 or more to form a light spot on the recording medium by condensing an incident light beam emitted from the light unit. A recording medium has a recording density of a DVD family or more and is formed of a material suitable for a long wavelength of 700 nm or more so that a reproduction signal by a reflectance of a recording surface is optimized. Thus, a compact high density optical recording/reproducing apparatus which is inexpensive and has high performance can be realized.

摘要： An actuator loading/unloading device includes a block unit disposed at a base of a disc drive to be positioned outside a disc, a lamp member positioned on the block unit so that the lamp member is lifted from or lowered down on the block unit, an actuator being parked on the loading/unloading device by constraining a side end portion of a swing arm of the actuator during loading/unloading of the actuator, a stopper to restrict a lifting range of the lamp member, and a lifting/lowering unit to lift or lower the lamp member between the block unit and the stopper. The lifting/lowering unit includes a magnet inserted into a bottom surface of the lamp member, and an electromagnet inserted into a top surface of the block unit, facing the magnet. As a result, the actuator is stably parked on the disc drive having a compact structure where the actuator cannot be completely escaped from the disc during unloading of the actuator.

摘要： A recording/reproducing apparatus having an optical pickup device which is efficient in light use having little spherical aberration. The recording and/or reproducing apparatus includes an optical pickup having an objective lens, disposed opposite a disk, having a light passing region divided into central, intermediate and periphery regions corresponding to a near axis area, an intermediate axis area and a far axis area of incident light, where the curvature of the central and peripheral regions is optimized for a thin disk and that of the intermediate region is optimized for a thick disk, a light source irradiating light toward a disk through the objective lens; a photo detector for detecting light reflected from the disk, and a beam splitter, disposed between the objective lens and the light source, for transmitting light from the light source toward the objective lens and for diffracting light reflected from the disks toward the photo detector; and a processing unit to process an information signal to control the incident light generated by the light source, and to process the detected light from the photodetector. Therefore, the optical pickup device can be used for both compact disks (CDs) that are thick using light beam passing the near and intermediate regions of said objective lens, and digital video disks (DVDs) that are thin using light beam passing the near and far axis regions of said objective lens, and detect signals without picking up noise regardless of the thickness of the disk.
