A method and apparatus for reducing power consumption in a display area of an electronic device such as a portable computer are provided. Such a method includes: (a) activating a mode of setting the display area to a white background screen using a first input command of a user; and (b) locating the white background screen over all windows, except for a current task window being displayed in part of the display area. Additionally, the apparatus for reducing power consumption in a display area includes an input unit receiving a first input command from a user; a mode activation unit for activating a mode of setting the display area to a white background screen according to a first input command from a user; and a location setting unit for locating the white background screen over all windows, except for a current task window being displayed in part of the display area. As a result, the lifetime of a battery of a portable computer is maximized by reducing power consumption in the portion of a display area that is not being used by a user.

Apparatus and method of processing touchpad input information are provided. The method includes mapping an input region of a touchpad to a display region as absolute coordinates, converting contact location coordinates into absolute coordinates, when a pointing tool touches the input region, and moving a mouse pointer displayed on the display region according to the converted contact location coordinates. The input region of a touchpad is mapped to a display region as absolute coordinates such that information can be directly input using the touchpad.

A belt configured to travel a continuous track may be incorporated for use in an image forming apparatus. The belt may include a guide member formed on a surface of the belt to prevent a belt from meandering off of the track, where the guide member may include a rubber sheet and a carbon black material having a primer particle diameter ranging from about 15 nm to about 35 nm. An image forming apparatus incorporating the belt with one or more guide members has an increased resistance to abrasion and mitigates belt meandering and image contamination.

A charging apparatus including a charging tube which has an outer surface contacting a photoconductive medium and electrically charges a surface of the photoconductive medium, a shaft which is disposed in the charging tube and to which a charging voltage is applied, and a conductive member which is connected to the shaft and contacts an inner surface of the charging tube. A friction coefficient between the conductive member and the inner surface of the charging tube may be less than a friction coefficient between the photoconductive medium and the outer surface of the charging tube, so that a slip phenomenon of the charging tube is prevented.

An actuator used with an optical pickup includes: a base on which a holder is fixed; a lens holder in which a plurality of installation holes are formed such that a plurality of objective lenses to record and/or reproduce optical discs having different recording densities are installed at different heights; a support member, which movably supports the lens holder, having one end coupled to the lens holder and the other end coupled to the holder; and a magnetic circuit which drives the lens holder in focusing and tracking directions. The plurality of installation holes include a first installation hole in which a first objective lens for at least one type of low density optical disc is installed, and a second installation hole in which a second objective lens for a higher density optical disc than the low density optical disc is installed. When a working distance of the first objective lens for the low density optical disc installed in the first installation hole is represented as WD1, and a working distance of the second objective lens for the high density optical disc installed in the second installation hole is represented as WD2, the first and second installation holes are provided so that the first and second objective lenses are installed to satisfy the Equation: WD1≧WD2, a separation distance between the optical disc and the second objective lens=WD2+α where, α=|WD1−WD2|×(0.1˜1.0). The second installation hole is located in a more outer circumference of the optical disc than the first installation hole.

A disk cartridge includes a case which receives a disk thereon, a cover which is installed on the case and includes an opening, and a shutter which is movably installed in the case, in a lower direction of the disk, to open and close an aperture formed on the case. The disk cartridge has guide holes formed on the case along a trace of the shutter, and support members formed on the shutter. The support members are guided along the guide holes while having ends thereof interfering with peripherals of the guide holes. Therefore, since the peripherals of the guide holes interfere with the ends of the support members, the shutter is prevented from being deformed even where an external force is applied to the shutter through the aperture, in a closed state of the shutter.

Provided is a communication adapter switching method and apparatus in a system having a plurality of communication adapters. The method includes: setting the addresses of the plurality of communication adapters equal to the address of the first of the plurality of communication adapters; setting a packet filtering mode of the communication adapters other than the first communication adapter to a mode in which all packets are accepted; and switching from one of the communication adapters to another when the one communication adapter is disconnected during communication. Accordingly, seamless handoff from the wired LAN to the wireless LAN is possible, since the TCP/IP session is maintained with the same IP address.
摘要:
A micro actuator for moving a head device in a track direction of a recording medium by a magnetic force generated between the magnetic cores. In normal use, the micro actuator is mounted on an actuator arm which pivots in a track direction across a track of the recording medium. The slider moves above the recording medium and has an accommodating portion facing the recording medium. A first magnetic core is arranged to move in the accommodating portion, for supporting the head device. A second magnetic core, separated a predetermined distance from and facing the first magnetic core, is installed in the accommodating portion such that the center of the first magnetic core in a magnetic direction, which is perpendicular to the track direction and horizontal with respect to the surface of the recording medium, is offset from the center of the first magnetic core. A first magnetic coil is wound around the first magnetic core so that the axis of the first magnetic coil runs in the vertical direction and a magnetic force in a direction perpendicular to a surface of the recording medium is generated when current is applied. Leaf springs elastically connects the first magnetic core and the inner side of the accommodating portion in the track direction. When current is applied to the first magnetic coil, the first magnetic core is moved in the track direction by a magnetic force generated between the magnetic cores.
