  • Publication number: 20240140735
    Abstract: The weight of a body-to-be-conveyed constituting a conveying device is reduced, and the friction force between the sliding surface of the body-to-be-conveyed and the conveyance path is reduced. A body-to-be-conveyed that is a component of a conveying device that uses electromagnetic force as thrust and can move in a horizontal direction includes a mover in which a bottom surface is arranged so that a predetermined gap is formed in a vertical direction with respect to the sliding surface thereof, in which the mover includes a permanent magnet and a cover, a gap facing surface of the permanent magnet facing the gap includes one magnetic pole, the cover is installed on a side of the permanent magnet opposite from the gap facing surface in the vertical direction, the horizontal outermost diameter of the cover is larger than the horizontal outermost diameter of the permanent magnet, and the cover is formed of a flat plate.

  • Patent number: 9946223
    Abstract: A cooling device, which is included in an image forming apparatus, includes a cooling device including an air blower, an airflow divider, an air flowing passage, and an air exhaust opening. The air blower blows air toward a cooling target device. The airflow divider divides the air exhausted from the air blower into at least two airflows such that an air flowing direction of the air is changed to a direction perpendicular to an air exhausting direction of the air. The at least two airflows pass through the air flowing passage. A wall of the air flowing passage is disposed facing the cooling target device. The air exhaust opening is disposed on the wall of the air flowing passage to cause the air to pass through toward the cooling target device disposed in a direction intersecting the air flowing direction in the air flowing passage.
