Abstract: An electronic device of the present disclosure includes: a first housing that includes a first outer surface including a keyboard and includes a second outer surface opposite to the first outer surface; a second housing that houses a display and is connected to the first housing; and a speaker unit disposed inside the first housing. The second outer surface includes a recess. A recess includes a through hole in at least a part of a surface of the recess. At least a part of the speaker unit faces at least a part of a back surface of the surface of the recess including the through hole.

Abstract: A battery pack includes: a battery case; a battery that is housed in the battery case and configured of a pouch type cell having a first plane and a second plane disposed on an opposite side of the first plane; and an adhesive layer that is arranged between at least one of the first plane and the second plane of the battery and an inner surface of the battery case in a shape of a frame along an outer edge of the battery.

Abstract: An electronic device includes a housing, a covering member that covers the housing, and an attachment part that detachably attaches the covering member to the housing. The attachment part includes a one-side attachment part and at least one other-side attachment part. The one-side attachment part includes a first projection of the covering member extending from a first member toward a second member, a first accommodation part of the housing that accommodates the first projection, and a first movement restriction part that restricts movement of the first projection. The other-side attachment part includes a protrusion of the covering member extending from a second member toward a third surface of the housing, a second projection extending from the protrusion in a direction away from the first member, a second accommodation part of the housing that accommodates the second projection, and a second movement restriction part that restricts movement of the second projection.

Abstract: An electronic device includes a first housing including a display unit, and a second housing that includes an input unit and an antenna unit, is rotatably connected to the first housing via a connection part, and is made of a metal material. The first housing includes a support plate that constitutes a back surface of the first housing, supports the display, and is made of a metal material, and a communication path member that is provided on the support plate and is made of a resin material. The communication path member is disposed in a region facing at least a part of the antenna unit of the second housing in a closed state where the first housing and the second housing are disposed to face each other.

Abstract: The present invention provides a process cartridge includes a first unit and a second unit separable (detachable) from the first unit. The first unit includes a photosensitive member, a developing unit that forms an image on the photosensitive member, and a cleaning unit that collects residual toner from the photosensitive member. The second unit includes a toner hopper unit that supplies toner on the photosensitive member, and a waste toner box that stores the collected residual toner. The developing unit engages with the toner hopper unit so as to engage the first unit with the second unit.
