Abstract: According to one embodiment, each of the first piece portions of a fixing ring is elastically deformed with a first bent portion to be bent toward a first surface side serving as a point of origin. In a map shape formed by projecting a plurality of broad portions and the first piece portions onto a virtual plane parallel to the first surface, each of the first bent portion intersects a straight line passing through a contact point of a circumscribed circle in contact with an outer circumferential edge of the broad portion on which the first piece portion is provided and a center point of the circumscribed circle. Each of the first piece portions is positioned between an inscribed circle in contact with an inner circumferential edge of the first piece portion and the first bent portion.

Abstract: A camera is detachably attached to the central portion of the rear end of an apparatus main body of a personal computer and positioned between a pair of hinge portions. A lens is provided at the camera main body of the camera and this camera main body is rotatably arranged about the axis of the camera main body substantially coaxial with the rotation axis of a display unit. When the camera main body is detached from the apparatus main body, the camera is connected to the apparatus main body through an extension adapter and put at a remote position from the personal computer. A shutter button is provided at each of the camera main body and the apparatus main body.

Abstract: An electronic apparatus including a first housing and a second housing. The first housing has a top wall, a left side wall, and a right side wall. The second housing is supported on the first housing. The top wall has a plurality of stepped parts at its peripheral parts that are connected to the left side wall and the right side wall. The stepped parts incline, lying at a level lower than the top wall. The second housing can be rotated from a closed position to an opened position, and vice versa. The second housing covers the top wall when in the closed position, and stands upright and exposes the top wall when in the opened position. The second housing has a plurality of extensions that cover the stepped parts when in the closed position.

Abstract: A portable electronic device comprises a main body comprising a keyboard provided on a surface thereof and incorporating a content recording section, a display comprising a display surface facing to the keyboard and rotatably mounted on the main body, and an operating button which controls reproduction of contents stored in the content recording section and is provided at a portion on the surface of the body which is not covered by the display even if the display is closed.
