  • Counter-rotating fan and image capturing device
    Patent number: 11388319
    Abstract: Sound is reduced after securing sufficient air volume. An intake side fan including a first housing, a first drive motor that functions as a drive source, a first hub that is rotated by drive force of the first drive motor, and a plurality of first impellers that is rotated along with the first hub; and an exhaust side fan including a second housing, a second drive motor that functions as a drive source, a second hub that is rotated by drive force of the second drive motor, and a plurality of second impellers that is rotated along with the second hub are provided. An axial maximum chord length of the first impellers is smaller than an axial maximum chord length of the second impellers.

  • Imaging device unit and imaging apparatus
    Patent number: 8106952
    Abstract: An imaging device unit includes: an imaging device having an imaging surface located on one side thereof in a width direction thereof and a rear surface located oppositely to the imaging surface; a heat radiating plate radiating heat generated in the imaging device, the heat radiating plate being arranged at the rear surface of the imaging device; and a signal processing substrate causing the imaging device to be operated. The heat radiating plate and the signal processing substrate are arranged opposedly to each other with a spacer being interposed therebetween and with a space portion being obtained therebetween.
