  • Patent number: 11507136
    Abstract: An electronic apparatus includes: a chassis having lateral surfaces including a frame and a rear surface including a glass plate supported by the frame; and a display having a display surface facing a front surface of the chassis. The frame includes a frame-shaped outer wall defining the lateral surfaces of the chassis; and a glass support that protrudes from the outer wall towards in inward direction of the frame. The glass support extends along an edge of the glass plate and includes a missing part that is a divided portion. The electronic apparatus further includes a metal plate that is thinner than a portion of the glass support adjacent to the divided portion. The metal plate is fixed to the frame, supplements the divided portion, and supports the glass plate together with the glass support.

  • Patent number: 11388828
    Abstract: A chassis member is used for an electronic device, including a face plate, and a frame to be fixed to one face of the face plate and provided along at least one side of a peripheral edge of the one face. The frame is formed by laminating a plurality of layers of a prepreg containing reinforced fiber impregnated with resin. The frame has a frame body to be fixed to the one face, and a shaft supporting portion formed integrally with the frame body and formed with an insertion hole for press-fitting a shaft-like member.
