  • Patent number: 9665062
    Abstract: A housing structure includes an exterior cover having an opening through which an interior of the exterior cover communicates with an exterior of the exterior cover, an interior cover disposed inside the exterior cover and facing the exterior cover with a clearance secured therebetween, an inward projection projecting from the exterior cover to the interior cover, and an outward projection projecting from the interior cover to the exterior cover. The inward projection and the outward projection define an airflow passage in the clearance between the exterior cover and the interior cover, and the airflow passage includes multiple bent portions. The outward projection is greater in width than the inward projection in an airflow direction toward the opening, and the airflow direction perpendicular to a direction in which the interior cover faces the exterior cover.

  • Publication number: 20160182756
    Abstract: An image forming apparatus includes a first human body detector, a second human body detector, and a controller. The first human body detector has a first detection span to detect a human body to output a signal. The second human body detector has a second detection span to detect a human body to output a signal. The controller changes a state of the image forming apparatus from a standby state to an operation state in accordance with the output signal from each of the first human body detector and the second human body detector. A first center line of the first detection span intersects with a second center line of the second detection span at a portion where the first detection span and the second detection span overlap with each other in a planar view.

  • Patent number: 9229420
    Abstract: A cover open/close mechanism, which is included in an image forming apparatus, includes a cover having a free end and disposed movable between a closed state that a part of the apparatus body is covered and an open state that the covered part is exposed, a cover rotating shaft about which the cover rotates in a receding direction when the cover moves from the closed state to the open state, a support member rotating shaft disposed parallel to the cover rotating shaft, a cover rotating shaft support member to support the cover rotating shaft and to change a position of the cover rotating shaft with respect to the apparatus body by rotating about the support member rotating shaft, and a biasing member to bias the cover rotating shaft support member in a manner in which the cover rotating shaft support member rotates in an approaching direction.
