    • Disclosed is an image processing method for processing an image obtained by reading a document plate on which at least one document is placed. The method includes a first detecting step of specifying a first rectangular region including all of objects included in the image to detect the coordinates of each vertex thereof, an identifying step of identifying on each object whether it is a document item, an eliminating step of eliminating the object which is not a document item from the image, a second detecting step of specifying a second rectangular region to detect the coordinates of each vertex thereof, the region including all of the objects after elimination and having a minimum area, a comparing step of comparing the coordinates of the vertices detected in the first and second detecting steps, and a determining step of determining a method of cropping the document based on the comparison result.

    • A magnetic disk apparatus includes a magnetic disk, a spindle motor for rotation of the magnetic disk, and a slider formed with a magnetic head for information reading or writing with respect to the magnetic disk. The slider is arranged to float above the surface of the magnetic disk when the disk is rotating. The magnetic disk apparatus also includes a swing arm for supporting and moving the slider above the magnetic disk, and a ramp disposed adjacent to the outer circumference of the magnetic disk for holding the slider at a withdrawal position which is spaced away from the surface of the magnetic disk. For an information leakage prevention, a hitting mechanism is provided, which is arranged to hit the slider held at the withdrawal position.

    • A disk drive includes a rotatable disk, a read/write head, a head actuator for moving the head, a suspension for connecting the head and the actuator, and a housing for accommodating the disk, the head, the actuator and the suspension. The suspension is provided with a tab, and the housing is provided with an engaging element to come into engagement with the tab. Upon application of an impact to the housing, the head is raised unduly away from the disk. The tab is caught by the engaging element, thereby preventing the head from falling to and colliding with the disk.
    • 磁盘驱动器包括可旋转盘,读/写头,用于移动头的头致动器,用于连接头和致动器的悬架,以及用于容纳盘,头,致动器和悬架的壳体。 悬架设置有突片,并且壳体设置有接合元件以与突片接合。 当对壳体施加冲击时,头部被不适当地从盘上升起。 卡舌被接合元件卡住,从而防止磁头掉落并与磁盘碰撞。
