  • Patent number: 11943529
    Abstract: An imaging apparatus, not including a display that displays setting information for operation setting in the imaging apparatus, includes: an image sensor that captures a subject image to generate image data; an output interface connected to an external apparatus to output the image data; and a controller that controls an output setting for outputting the image data in a predetermined format from the output interface to the external apparatus. In a state where the output setting is applied, no setting information for canceling the output setting is displayed on the external apparatus serving as an output destination of the image data in the predetermined format by the output interface. The imaging apparatus further comprises an input interface that receives an instruction to cancel the output setting from the state where the output setting is applied.

  • Publication number: 20230207235
    Abstract: Provided herein is a keyboard assembly that includes a keyboard substrate, a plurality of keycaps, and a plurality of lifting supports. Each keycap is connected to the keyboard substrate by using a lifting support. The keyboard substrate is connected to a bottom plate and a top plate, with the bottom plate including a key accommodation groove that further includes a concave slope. The lifting support is located in the key accommodation groove, with one end abutting against the concave slope and being capable of sliding on the concave slope. In a process in which the top plate rotates to a first specified location, the keyboard substrate is driven to move, the lifting support descends, and the keycap descends. In a process in which the top plate rotates to a second specified location, the keyboard substrate is driven to move.

  • Patent number: 10088873
    Abstract: A chassis structure is disclosed. A chassis includes a plate-like body in which a foam layer is located between a pair of fiber-reinforced resin plates, and a frame body formed of a thermoplastic resin and joined to a peripheral portion of the plate-like body. The plate-like body is configured such that its peripheral portion is formed by an ear-like joint portion where the pair of fiber-reinforced resin plates are joined together without the foam layer located therebetween, thereby sealing the foam layer inside the pair of fiber-reinforced resin plates. The frame body is joined to the plate-like body in a state where the frame body is in contact with the joint portion.
