    • An image processing apparatus that enables to prolong lives of device parts of which lives are limited by preventing unnecessary returns from the power saving mode, and reduce unnecessary power consumption. A first living body detection unit detects a living body that approaches the apparatus to input a trigger. A second living body detection unit detects a living body that approaches the apparatus for other purposes. A switching unit switches a mode from a first electric power mode to a second electric power mode when the first living body detection unit detects the living body and when the second living body detection unit does not detect the living body, and maintains the first electric power mode when the first living body detection unit detects the living body and when the second living body detection unit detects the living body.
    • 通过防止来自省电模式的不必要的返回,能够延长寿命的设备部件的寿命的图像处理装置受到限制,并且减少不必要的功率消耗。 第一生物体检测单元检测接近装置的生物体以输入触发。 第二生物体检测单元检测靠近该装置的生物体用于其他目的。 当第一生物体检测单元检测到生物体并且当第二生物体检测单元不检测生物体时,切换单元将模式从第一电力模式切换到第二电力模式,并且保持第一电力 模式,当第一生物体检测单元检测到生物体时,以及当第二生物体检测单元检测到生物体时。

    • Embodiments of the present invention relate to retracting a magnetic head of a disk drive device to a retract position in accordance with a fall state, and to suppressing the performance degradation due to erroneous fall determinations as well as occurrence of damage by a head-disk crash. According to one embodiment of the present invention, in a Hard Disk Drive (HDD), a servo controller moves a head slider to a cylinder at the side of a ramp at a predetermined timing that a fall determiner determines that it is falling and an unload controller starts an unload process. This shortens the time between determination by the fall determiner that it is falling to retraction of the head slider to the retract position. Furthermore, it prevents increase of the erroneous determinations by relaxing the fall determination condition for safety. Also, it shortens the time that the head slider returns to the initial position before the seek in case that it is not determined that it is falling.
    • 本发明的实施例涉及根据跌倒状态将盘驱动装置的磁头回缩到缩回位置,并且抑制由于错误的下降判定引起的性能下降以及头盘崩溃的损坏的发生 。 根据本发明的一个实施例,在硬盘驱动器(HDD)中,伺服控制器在预定定时将磁头滑块移动到斜坡侧的气缸,以便下降确定器确定其正在下降并且卸载 控制器启动卸载过程。 这缩短了下降确定器确定其下降到头部滑块缩回到缩回位置之间的时间。 此外,通过放松用于安全的跌倒判定条件,防止了错误判定的增加。 而且,如果没有确定它正在下降,它会缩短磁头滑块在搜索之前返回到初始位置的时间。
