    • An image forming apparatus and a fixing unit thereof are disclosed. The fixing unit includes a heating roller, a press roller mounted in close contact with the heating roller to apply heat and pressure to the printable medium with the heating roller, a press lever to press the press roller toward the heating roller, a press spring connected to the press lever, a release device to operate the press lever to release pressing force exerted on the press roller, and a power conversion device to transmit driving power generated from a main driving source to drive the heating roller to the release device. Accordingly, since the press lever pressing the press roller to closely contact the heating roller can be operated by the driving power of the main driving source, the jammed printable medium can be easily removed.
    • 公开了一种图像形成装置及其固定单元。 定影单元包括加热辊,与加热辊紧密接触的加压辊,用加热辊对可印刷介质施加热和压力;压力杆将加压辊压向加热辊;压力弹簧连接 向压力杆施加释放装置,以操作压力杆以释放施加在压辊上的压力;以及电力转换装置,用于传递从主驱动源产生的驱动力,以将加热辊驱动到释放装置。 因此,由于按压压辊以紧密接触加热辊的压杆可以通过主驱动源的驱动力来操作,所以可以容易地去除可卡住的可打印介质。

    • A method and apparatus for transmitting data to an Access Point (AP) and a Mobile Station (MS) in a Time Division Duplex (TDD) optical repeater. A main donor generates a control frame for controlling a remote, upon receipt of data from the AP, and transmits the control frame to the remote during a non-downlink transmission period. The remote analyzes the control frame received from the main donor, detects sync information about a downlink signal and an uplink signal, and remote control information from the analyzed control frame, performs a control operation according to the detected remote control information, and generates a status frame for notifying the main donor of the status of the remote upon receipt of data from the MS. The status frame is transmitted from the remote to the main donor during a non-uplink transmission period.
