  • Patent number: 6643474
    Abstract: It is an object of the invention to enable a maintenance work to be executed with appropriate timing. When jam occurrence is detected by jam sensors placed in a plurality of positions in a sheet transporting path, a control section changes a display state such as a shape and a blinking period of a mark in a display section, in accordance with history information which is stored in a storage section. When the display contents of the display section is visually checked, the part where the jam has occurred can be identified from the display position of the mark, and the jam occurrence history in the part can be known from the shape and the blinking period of the mark. Therefore, it is possible to correctly judge the necessity of a maintenance work.

  • Patent number: 6490123
    Abstract: A magnetic disk drive has a housing for a 3.5 inch form factor and disk media of a diameter for a 2.5 inch form factor. The smaller disk media rotate at a high speed while consuming low electric lower and generating less heat while providing for quick access speeds. Usually, when the magnetic disk media are rotated at a higher speed, the electric power consumption and heat generation are increased because of the load increase. This problem is avoided with the use of cooling fins placed about the periphery of the disk media. Further, the smaller size disk media enable a decrease in torque loss during on-load rotation with the media, and a decrease of electric current to the spindle motor during rotation.
